[0002] PCBA, or printed circuit board assembly, is the provider of electrical connections for electronic components. It uses electronic printing technology to print circuit graphics, component connection lines and insulating substrates on the board to achieve electrical connections between electronic components. PCBA circuit boards are an indispensable part of electronic equipment and are widely used in various electronic products.

[0003] The production process of PCBA circuit boards mainly includes the following steps: board preparation, pattern transfer, etching, solder mask production, silk screen marking, SMT patch welding, testing and quality inspection, assembly and packaging.

[0004] In the production of PCBA circuit boards, the circuit boards need to be transported many times.

[0032] Working principle: During operation, the circuit board is fed into the gap between adjacent clamping plates 15. During the movement of the circuit board, the circuit board will come into contact with the rotating wheel 19. When the rotating wheel 19 and the circuit board rub against each other, the rotating wheel 19 will rotate and will slide along the fixing hole 16 under the pressure of the circuit board. When the rotating wheel 19 moves, it will drive the connecting rod 18 to move together. When the connecting rod 18 moves, the arc-shaped piece 17 will bend until the rotating wheel 19 completely enters the fixing hole 16. At this time, the surface of the circuit board will come into contact with the clamping plate 15, and at the same time, one side of the circuit board will come into contact with the fixing plate 14. Then, another set of connecting plates 13 will be slid to drive another fixing plate 14 to approach the circuit board. During the approaching process, the other fixing plate 14 The other side of the circuit board will enter the gap between the clamping plates 15, and finally the two sides of the circuit board will abut against the two fixing plates 14. At this time, the device completes the clamping and fixing of the circuit board, and then the device body 1 can be pushed to transport the circuit board to the next work surface; when the circuit board moves in the gap between the clamping plates 15, the angle of the arc-shaped piece 17 will change, and when the angle of the arc-shaped piece 17 changes, the rotating rod 2 will slide along the clamping plates 15, and when the rotating rod 2 slides, it will drive the pressing plate 22 to move together. When the pressing plate 22 moves, it will reach the surface of the circuit board and come into contact with the circuit board, thereby increasing the contact area between the device and the circuit board; when the pressing plate 22 moves toward the circuit board, it will come into contact with the circuit board, and the rubber pad 3 will be between the pressing plate 22 and Before the circuit board contacts, it will first come into contact with the circuit board. Because the friction coefficient on the surface of the rubber pad 3 is larger, the friction between the device and the circuit board will be increased. At the same time, because the rubber pad 3 is a flexible material, it will absorb the impact generated when the pressure plate 22 and the circuit board come into contact, reducing the impact on the circuit board. When the circuit board enters the gap between the clamping plates 15, it will come into contact with the buffer plate 42. After the buffer plate 42 is squeezed by the circuit board, it will transfer the pressure to the damping spring 4. After the damping spring 4 is pressed, it will absorb the pressure and be in a compressed state. Then the damping spring 4 will release the elastic potential energy and apply elastic force to the buffer plate 42, and then the buffer plate 42 will squeeze the circuit board. When the circuit board and the buffer plate 42 come into contact When the electronic components on the surface of the circuit board come into contact with the suction cup 5, the air in the suction cup 5 will be discharged, and the suction cup 5 will adsorb the surface of the circuit board under the action of atmospheric pressure; when the connecting plate 13 is moved, the scraper 6 will also move with the connecting plate 13, and the scraper 6 will rub against the sliding rod 12 when moving. During the friction, the scraper 6 will remove the impurities attached to the surface of the sliding rod 12, thereby improving the smoothness of the surface of the sliding rod 12; the oil bag 7 is injected with lubricating oil, and when the scraper 6 slides, the elastic cloth 62 will bend, and when the elastic cloth 62 bends, the oil bag 7 will also be squeezed, and the lubricating oil in the oil bag 7 will flow out from the round hole 72 and reach the surface of the sliding rod 12, thereby improving the smoothness of the surface of the sliding rod 12.
