Vision Alignment System for Laminating Machine
The performance of CCD hardware currently used in chip machine lenses is of a comparable level. In the CCD hardware development earlier developed "Back-Lighting" (Back-Lighting) and "Front-Lighting" (Front-Lighting) technology and programmable lighting control to better cope with different component placement needs.
Light" (Front-Lighting) technology, as well as programmable lighting control, to better cope with a variety of different component placement needs. For example, simple components such as resistors and capacitors are illuminated from behind, and the vision system can reliably align them by simply recognizing the body outline. Conversely, dense-pin components such as QFPs* are better illuminated from the front, showing the complete distribution of pins around the package so that the vision system can reliably identify the alignment. Some BGAs have visible alignments on the bottom side of the component that can confuse the vision system, and these components require a side lighting system. It will illuminate the solder balls from the side instead of the alignment on the bottom side, so the vision system can check the solder ball distribution and correctly identify the component.
The highly** optical unit, flexible illumination and high resolution camera integrate the *optimal* image of the circuit and device, so that the feedback needed to correct board, component and feeder changes can be obtained by modern algorithms that are vital. Vision systems play an important role in successful placement equipment. By using advanced vision technology devices, higher levels of placement rates can be achieved. Defects occurring in pick-up are reduced, thus contributing to increased production on the entire production line and increased economic efficiency.
Vision systems are generally classified as overhead, elevation, head or laser aligned, depending on the location or type of camera.
(1) elevation camera is used to detect components in a fixed position, generally using CCD technology, before installation, the components must be moved over the camera in order to do visual alignment process. Roughly speaking, it seems to be a bit time-consuming. However, since the mounting head must be moved to the feeder to collect the components, if the camera is mounted between the pick-up position (from the feeder) and the mounting position (on the board), the vision acquisition and processing can be done simultaneously during the movement of the mounting head, thus shortening the mounting time.
(2) The overhead camera is mounted on the mounting head and is used to search for targets (called references) on the board in order to place the board in the correct position prior to placement.
(3) Laser alignment is to generate a moderate beam from a light source and shine it on the component to measure the impact of component projection. This method measures the size and shape of the component as well as the deviation of the center axis of the nozzle. This method is fast, because it does not require walking over the camera. However, its main drawback is that it can not pin and dense-pin components for pin inspection, for sheet components is a good choice. 90's laser alignment technology was introduced only to deal with 7´7mm components, the current ** generation of laser alignment system introduced by Anbion to deal with component size increased to 18´18mm, the laser technology can identify more shapes, the accuracy has also improved significantly.
(4) the head camera is installed directly in the mount head, generally uses the line-sensor technology, in the process of picking up the component to move to the designated position to complete the detection of the component, this technology is also called "the flight alignment technology", it can greatly improve the mount efficiency. The system is composed of two modules: one module is the light source module composed of light source and lens. The light source adopts LED light-emitting diode and scattering lens, and the light source lens forms the light source module. Another module is accepting module, using LineCCD and a set of optical lens to form accepting module. These two modules are installed on both sides of the chip head spindle, with the spindle and other components to form the chip head, the chip machine has several chip head, there will be a corresponding set of several systems.

SMT equipment analysis
Looking ahead, "flexible", multi-tube arch mount equipment will be the choice of small to mid-size, order-based assembly manufacturers. The ideal equipment to meet this market is one that has the ability to place a wide range of devices from 0201 to large Quad Flat pack (QFP) devices at high speeds. Purchasing a device with much more functionality than is currently required can often avoid future business opportunities that may be missed. Upgrading an existing machine is much more economical than purchasing a new one. Based on the above, many** placement equipment manufacturers have introduced machines with multiple placement heads in various configurations, such as Universal's GC60, Panasonic's CM602, Hitachi's GHX-1, Siemens' HS60, Fuji's NXT, etc., and are gradually replacing turret machines in the dominant position in the high-speed machine market.
*In the last five years, more and more companies are preferring placement equipment with flexible features, an "eclectic" solution that combines high placement speed and a large number of feed positions compared to conventional high **degree modules. These platforms are still capable of meeting the full range of placement needs of most components, from *small passive devices to *large active devices. For example, the Siplace device from Siemens uses a unique flexible means of pick-and-place system for placement, while the vertical rotary head system can be used to pick up to 12 components. Many other types of arch-mounted, pick-and-place devices use a multi-pipe workhead. Simultaneous "swarm" pickups can be used to achieve high placement speeds. However, this type of simultaneous pickup does not handle small components well because it requires extremely neat alignment between the nozzle and the feeder. It is not possible to do it extremely neatly on these devices. The alternative is to pick up the components individually, which inevitably increases the time spent on placement considerably. In this way, the machine with multiple mounting head frame will be greatly popular, including multi-arm type, compound type, large parallel system, etc. These models are also called "module machine", because it can flexibly add different types of mounting unit according to the future demand, to meet the future flexible production demand, when the product has changed, can promptly improve The ability to adapt the work of the equipment is very important, because the new package and circuit board brings new requirements.
At present with the placement equipment market continues to mature, from one platform to another platform the difference becomes smaller and smaller. Because of this, the purchaser of placement equipment should focus on more than the manual, the evaluation of the equipment is **, not only look at the hardware but also should focus on the software and consider the following key factors: machine type, imaging, and flexibility, with this understanding, it is possible to identify the advantages and disadvantages of different equipment and make an informed choice.

Used SMT equipment market analysis
I. Overview
The used SMT equipment we are talking about is the used SMT equipment. In Europe and the United States, it is customary to call "Used SMTMachines" and generally do not say "SecondHandMachines", Taiwan and Hong Kong are used to call "used SMT equipment". ", in mainland China used to be called "used SMT equipment".
SMT industry after more than 40 years of development, in 40 years, SMT equipment demand and market ownership are increasing at an annual growth rate of 10%-20%. In these 40 years, some SMT factories began to replace the old with new or close down, which has a source of supply of used SMT equipment; at the same time, some SMT companies began to look for used SMT equipment in order to save cost investment, which has a potential market demand. After 30 years of development, used SMT equipment has become an important branch of SMT equipment and is increasingly active in the SMT equipment market as a necessary supplement to the new SMT equipment market.
With the development of the SMT industry, due to the obvious price advantage of used equipment, although the used SMT equipment market is unlikely to become the dominant market, but will certainly increasingly occupy the entire SMT equipment market share.
II. The development of used SMT equipment in the country
After more than 30 years of development, the domestic SMT industry has now become the country with more SMT equipment* in the world. In terms of the nature of enterprises, over the past 30 years, there have been many SMT enterprises from Europe, America, Taiwan and Hong Kong investing in the mainland, and these enterprises are also the main demanders of SMT equipment; at the same time, the number of SMT equipment owned by numerous mainland enterprises and research institutions is increasing day by day, and is estimated to account for about a quarter of the market share. In terms of geographical distribution, the Pearl River Delta region still dominates, followed by the Yangtze River Delta region, and again by various electronic enterprises and research institutions distributed in other provinces in China.
Used SMT equipment in the domestic development has been more than ten years of history, the last decade is also the domestic SMT * for the active decade. It is estimated that the current annual demand for used SMT equipment, including automatic printing machines, dispensing machines, placement machines and reflow soldering and other major equipment in more than 3,000 units, the market amount is estimated at about 500 million. If you look at the number of units traded, used equipment transactions are estimated to account for about one-third of the SMT equipment market share; if you look at the transaction amount, it is estimated that the transaction amount of used equipment will also account for about 15%.
Currently, due to the impact of the global financial crisis, many enterprises are increasingly rational investment, in order to save costs, have begun to examine the evaluation and favor used SMT equipment, which brings new opportunities for the development of the used SMT equipment market.
III. The source of used SMT equipment and supply channels
If the quality of used equipment to be divided, usually from Europe and the United States and Japan equipment is superior, Southeast Asian equipment is the middle class, domestic equipment for the lower class. The reason is simple, Europe and the United States and Japan equipment on the one hand, the use of short time, the mechanical wear and tear of the equipment is small; on the other hand, the maintenance of strict norms, so that the use of equipment in good condition. Although the use of Southeast Asian equipment is not short, but mainly from large enterprises, maintenance is relatively good domestic enterprises, so it is the middle class. Domestic equipment, many cases of 24-hour continuous operation, and generally in order to save costs and do not pay much attention to the regular maintenance required by the equipment. In the case of domestic equipment, the equipment of large enterprises is usually better than the used equipment of small and medium-sized enterprises, which is mainly caused by equipment management.
How does used equipment come about? There are several aspects that form the rich source of used SMT equipment. One is the normal retirement of enterprises, in many large foreign companies, the use of new equipment set for about five years, regardless of the condition of the equipment, all out of the old for the new. Some are the formation of a certain system within the enterprise, due to replace; some are from the finance company loans to buy the machine, to a certain time to the finance company loans to buy new machines and the old machine will be handed over to the finance company to deal with. Second, the company's transformation or multinational relocation, with the professional EMS companies have become an independent branch of incr
