Description

Technical Field

[0001] This utility model relates to the field of PCBA circuit board pressing technology, specifically to a PCBA circuit board pressing equipment. Background Technology

[0002] PCBA (Printed Circuit Board Assembly) is a key process in electronics manufacturing. It is mainly used to precisely mount electronic components such as chips, resistors, and capacitors onto a PCB (Printed Circuit Board), ensuring the robustness of the components and the reliability of the electrical connections. PCBA assembly uses mechanical or pneumatic equipment to press electronic components onto designated positions on the PCB, ensuring close contact with pads or pins for subsequent soldering or fixing. This ensures precise alignment between the components and the PCB, improves the mounting stability of the components, and prevents loosening or detachment. PCBA assembly equipment is widely used in the electronics manufacturing industry, such as consumer electronics, automotive electronics, communication equipment, and industrial control.

[0003] In existing PCBA press-fitting equipment, the circuit board directly bears the impact force of the press-fitting head during the press-fitting process, lacking a buffering mechanism. Excessive impact force may cause the circuit board to deform, the pads to fall off, or the internal circuits to break. Brittle components such as ceramic capacitors and glass-packaged chips are easily damaged by impact during the press-fitting process. The lack of buffering may lead to inaccurate alignment between components and pads, affecting the soldering quality. Therefore, a novel PCBA circuit board press-fitting equipment is needed.

Figures 1 to 4As shown, the system includes a base 1, a pressing machine 2 fixedly connected to the top of the base 1, a guardrail 3 fixedly connected to the top edge of the base 1, a moving component 4 at the bottom of the base 1, and a buffer component 5 at the top of the moving component 4. The buffer component 5 includes a support plate 501, a placement box 502 fixedly connected to the top of the support plate 501, a guide rod 503 fixedly connected inside the placement box 502, a spring 504 sleeved on the outer wall of the guide rod 503, and a sliding sleeve 505 fixedly connected to one end of the spring 504. The sliding sleeve 505 is connected to the placement box 502 via the guide rod 503. The sliding structure is formed, and the outer diameter of the guide rod 503 matches the inner diameter of the sliding sleeve 505. The outer wall of the guide rod 503 is fitted against the inner wall of the sliding sleeve 505, strengthening the connection between the sliding sleeve 505 and the guide rod 503. This allows the sliding sleeve 505 to slide along the outer wall of the guide rod 503. The placement box 502 forms an elastic structure with the sliding sleeve 505 via a spring 504. The spring 504 is positioned between the placement box 502 and the sliding sleeve 505, further strengthening the connection between the placement box 502 and the spring 504. This allows the spring 504 to slide within the placement box. Supported by the box 502, the sliding sleeve 505 is supported. A connecting rod 506 is movably connected to the top of the sliding sleeve 505, and a placement plate 507 is movably connected to the top of the connecting rod 506. A second electric push rod 508 is fixedly connected to the top of the placement plate 507. The sliding sleeve 505 and the placement plate 507 form a support structure through the connecting rod 506 and the placement plate 507. The connecting rod 506 is positioned between the sliding sleeve 505 and the placement plate 507 to enhance the connection between the connecting rod 506 and the sliding sleeve 505. This allows the placement plate 507 to push the sliding sleeve on the connecting rod 506 when subjected to force. 505 slides, and the circuit board is positioned by the second electric push rod 508. In addition, during the downward movement of the press machine 2, the press machine 2 can apply pressure to the circuit board, which can push the placement plate 507 downward. The placement plate 507 can push the bottom connecting rod 506, which can push the sliding sleeve 505 to slide along the outer wall of the guide rod 503. The sliding sleeve 505 can apply pressure to the spring 504. With the support of the spring 504, the support and buffering effect of the circuit board can be improved.

[0022] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the movable component 4 includes a mounting box 401. A motor 402 is fixedly connected to one side of the mounting box 401. A screw 403 is fixedly connected to the output end of the motor 402. A threaded sleeve 404 is threadedly connected to the outer wall of the screw 403. The motor 402 forms a threaded structure with the screw 403 and the threaded sleeve 404. The outer diameter of the screw 403 matches the inner diameter of the threaded sleeve 404, and the outer wall of the screw 403 fits snugly against the inner wall of the threaded sleeve 404, enhancing the connection between the motor 402 and the screw 403. This allows the motor 402 to rotate within the threaded sleeve 404 by driving the screw 403. A movable frame 405 is fixedly connected to the outer wall of the threaded sleeve 404. A first electric push rod 406 is fixedly connected to one side of the movable frame 405. A sliding plate 407 is fixedly connected to one end of the first electric push rod 406. The movable frame 405 forms a sliding structure with the slide plate 407 via the first electric push rod 406, and one end of the first electric push rod 406 passes through the movable frame 405 and the slide plate 407 to connect them, which strengthens the connection between the movable frame 405 and the first electric push rod 406. With the support of the movable frame 405, the first electric push rod 406 can drive the slide plate 407 to move. By starting the motor 402, the motor 402 can drive the screw 403 to rotate in the threaded sleeve 404, which allows the movable frame 405 to move horizontally along the threaded sleeve 404. At the same time, starting the first electric push rod 406 on the movable frame 405 can push the slide plate 407 to move, which in turn causes the placement box 502 to move laterally, thereby achieving the pressing and mounting of the circuit board at different positions.

[0023] The working principle of this utility model is as follows: During use, the circuit board can be placed on the placement plate 507, and the circuit board can be positioned by the second electric push rod 508. Furthermore, during the downward movement of the pressing machine 2, pressure can be applied to the circuit board, causing the circuit board to push the placement plate 507 downwards. This causes the placement plate 507 to push the bottom connecting rod 506, which in turn pushes the sliding sleeve 505 to slide along the outer wall of the guide rod 503. The sliding sleeve 505 then applies pressure to the spring 504. With the support of spring 504, the support and buffering effect on the circuit board can be improved. In addition, by starting motor 402, motor 402 can drive screw 403 to rotate in threaded sleeve 404, which can make moving frame 405 move horizontally along threaded sleeve 404. At the same time, starting the first electric push rod 406 on moving frame 405 can push slide plate 407 to move, which can make slide plate 407 drive placement box 502 to move laterally, thereby achieving the pressing treatment of circuit board at different positions.
