I. Preparation of power ;
1. DEK is a single-phase power supply, with ordinary plugboard.
2. as the power of JUKI KE2000 series is 3KW, the power of HELLER is 33KW, so it needs a 10KVA and a voltage regulator of more than 40KVA.
3. HELLER's power supply is 3-phase fire wire + 1 ground wire with a wire diameter of 25mm2.
4. JUKI's power supply for the 3-phase fire + 1 ground wire, the wire diameter of 6mm2.
Second, the workshop preparation.
1. add a layer of transparent diaphragm adhesive before entering the SMT workshop, or make a locker room.
2. treat the ceiling accordingly to reduce the consumption of cold air.
3. According to the size of the equipment and the planning of the production line, calculate the area required for the workshop.
Third, the preparation of air pressure

Problems that should be noted when dispensing glue

Problems that should be noted when dispensing glue
Products are prone to many defects in dispensing: substandard glue dot specifications, glue dipping, pulling, bad curing strength easy to fall off and other problems. To solve these problems, the overall study of its technical parameters should be.
1、Needle specifications
In the actual operation, the inner diameter of the needle specification should be about 1/2 of the diameter of the dispensing glue point, dispensing process, according to the industry specifications to select the dispensing needle. In the process of dispensing, the dispensing needle should be selected according to the industry specifications. Different needles should be selected for industries with different specifications, so as to ensure the quality of the glue dot and improve the production efficiency.
2、Dispensing pressure
The dispensing equipment provides a certain pressure to the syringe (glue gun) to ensure the glue supply, and the pressure specification determines the glue supply volume and glue flow rate. Too much pressure may cause glue overflow and too much glue; too little pressure may lead to intermittent glue dispensing and leakage, thus causing industrial defects. The pressure should be selected according to the nature of the glue and the operating temperature. High peripheral degree Celsius will make the glue viscosity smaller and fluidity better, then the pressure value should be adjusted down, and vice versa.
3、Specification of dispensing volume
According to the operation experience, the specification of glue dot diameter should be half of the industrial spacing. This will ensure that there is sufficient glue to bond the components and avoid too much glue. The amount of glue dispensed is determined by the length of time, and in practice, the dispensing time should be selected according to the production situation (room temperature, viscosity of the glue, etc.).
4、Viscosity of glue
The viscosity of glue directly affects the quality of dispensing. If the viscosity is large, the glue point will become smaller, even pulling; if the viscosity is small, the glue point will become larger, and then it may bleed into the industry. In the process of dispensing, the glue with different viscosity should be selected with reasonable pressure and dispensing speed.
5、The distance between the needle and the operating surface
Different dispensing machines use different needles, and some needles have a certain stopping degree. The calibration of the distance between the needle and the operating surface should be done before each operation starts, i.e. Z-axis height calibration.
6、Curing degree Celsius curve
For the curing of the glue, the manufacturer has generally given the Celsius curve. In practice, a higher degree Celsius should be used as far as possible to cure, so that the glue cured with sufficient strength.
7、Bubbles
The glue must not have bubbles. A small bubble will cause many industries without glue; every time when replacing the hose midway should empty the air at the connection to prevent the phenomenon of empty play.
8、Glue Celsius degree
The general epoxy resin glue should be kept in the refrigerator at 0~5℃, and taken out half an hour in advance when applying, so that the glue Celsius degree is consistent with the operation surrounding. The application degree of glue should be 23℃~25℃; the peripheral degree of Celsius has great influence on the viscosity of glue, the degree of Celsius decreases and the viscosity increases, the flow of glue becomes smaller accordingly, and the phenomenon of drawing is more likely to appear. The difference of 5℃ in the peripheral degree Celsius under the same condition will cause a 50% change of the glue output specification, so the peripheral degree Celsius should be controlled. At the same time, the surrounding temperature should also be given to ensure that the temperature is too high glue point easy to dry, affecting the bonding force.
9、The fluid instant glue which needs special setting: for water-based instant glue, apply **type piston and Teflon lined metal needle, for thick instant glue, apply conical slanting needle, if need flexible, apply PP needle.
Anaerobic glue: apply 10CC syringe and white PE general purpose piston.
UV glue: apply amber syringe, white piston and oblique needle (can cover UV) If you apply other kinds of needles, please order the needle that can cover UV.
Light-curing glue: Apply black opaque syringe to avoid light sensitivity.
Sealant and paste fluid: if the application of white piston rebound serious, please change to ** type live type, the application of oblique needle.
10、 Needle selection concise comparison table
In production should be adjusted in accordance with the actual situation of each parameter, both to ensure the quality of production, but also to improve production efficiency. For the adjustment of each parameter, should be adjusted by point and

AOI automatic optical inspection instrument
Automated Optical Inspection (AOI, Automated Optical Inspection)
I. Definition
Using high speed and high precision vision processing technology to automatically detect different kinds of mounting errors and soldering defects on PCB boards.
PCB boards can range from fine pitch high density boards to low density large size boards, and can provide in-line inspection solutions to improve production efficiency and solder quality.
