(Summary description)Measures to maintain SMT mounters 1. Strengthen the daily maintenance of the machine Mounting machine is a very complex high-tech high-precision machine, requires a constant temperature, humidity and very clean environment. Must be strictly in accordance with the requirements of the equipment to adhere to the daily, weekly, monthly, semi-annually, annually maintenance measures for routine maintenance. 2. Requirements for equipment operators (1) The operator should receive certain SMT professional knowledge and technical training. (2) Strictly in accordance with the operating procedures of the machine. Do not allow equipment operation with disease. Faults should be found in a timely manner to stop, and to the technical personnel responsible for or equipment maintenance personnel to report, remove before use. (3) require operators to concentrate on the operation process, to do eye, ear, hand hard. Eye diligence - to observe the machine operation process with or without abnormal phenomena. For example, the tape reel does not move, the plastic tape is broken, do not play INDEL mounting position is not correct. Ear diligence - ear to listen to the machine operation process there is no abnormal sound. For example, the abnormal sound of the mounting head, the loss of components abnormal sound, the abnormal sound of the transmitter, the abnormal sound of the scissors and so on. Hand hard - found anomalies in a timely manner to solve some of the minor problems operators can solve their own, such as picking up the plastic tape, reassemble the feeder, correct the placement position, play INDEX and so on. Mechanical and electrical problems, we must ask the maintenance staff to overhaul. 3. Develop measures to reduce or avoid errors In the mounting process, the most likely and most frequently occurring errors and defects is the wrong components and mounting position. Therefore, the following measures to prevent. (1) feeder programming, there must be a person to check and verify the feeder frame number position. Component value and programming table corresponding to the feeder number of component value is consistent. If inconsistent, must be corrected. (2) for the tape feeder, paste and install each plate of material and then on the material, there must be a person to check and verify the value of the new material on the plate is correct. (3) patch programming, must be edited once, check each placement step of the component number, mounting head rotation angle and mounting position is correct. (4) each batch of products mounted after the appropriate number of PCB, there must be a person to check. Problems found should be corrected in a timely manner by modifying the program and other methods. (5) mounting process, often check the mounting position is not correct; lost components more or less. Problems found in a timely manner to find the cause, and be excluded. (6) set up pre-soldering detection station, (artificial or AOI) In short, the mounting machine mounting speed and mounting accuracy is certain. How to play the role of the machine should be. The human factor is very important. To develop effective regulations and management measures to ensure the normal operation of the machine to ensure that the placement of quality and efficiency.
