Description

Technical Field

[0001] The invention relates to the technical field of PCB detection, in particular to an automatic flipping PCB etching circuit detection device. Background Art

[0002] With the rapid development of the electronics industry and the rapid development of PCB manufacturing technology, the quality and performance of PCB boards, as the core components of electronic products, directly affect the stability and competitiveness of the final products. In this context, the importance of PCB board etching circuit detection body as a key link in the PCB manufacturing process is self-evident. The detection body can perform comprehensive and detailed detection of the etching circuits on the PCB board, providing a solid quality guarantee for PCB manufacturing companies.

[0003] However, in the existing automatic flip PCB board inspection machine, since the existing clamping devices often sacrifice the flexible protection of the PCB board and the sensitive components thereon while pursuing stable clamping, these devices usually adopt high-strength clamping force to ensure that the PCB board does not move or fall off in the complex and changeable inspection environment. However, this high-strength clamping method is very likely to cause unnecessary physical damage to the PCB board when facing mechanical shock or vibration, especially for those delicate circuits and fragile components, which is a potential risk source. In addition, long-term excessive clamping also causes deformation of the PCB board, further affecting its performance and life;

[0004] Secondly, although the existing PCB board flipping mechanism has made some breakthroughs in achieving automation, the stability and continuity of the flipping process still need to be improved. The automated flipping equipment is designed to reduce manual intervention and improve production efficiency. However, in actual operation, due to minor collisions or imbalances in the flipping process, it is often difficult to ensure the absolute stability of the PCB board during the flipping process. At the same time, in order to maintain stability, some equipment adopts an over-clamping strategy, which limits the displacement space of the PCB board during the flipping process. This not only increases the difficulty of flipping, but also causes the PCB board to be unable to quickly return to a position suitable for the next test after flipping, thereby reducing the continuity and smoothness of the flipping operation;

[0005] Therefore, an automatic flipping PCB etching circuit detection device is proposed. Summary of the invention

[0048] The driver 1 23 , the driver 2 34 , the driver 3 43 , the detection body 52 , and the connection module 63 are all electrically connected to the external controller.

[0049] The working principle of the present invention in combination with the above is as follows:

[0050] In the initial state: the electric telescopic rod 31 is in a retracted state, the transport cylinder 33 is slidably connected to the outer surface of the transport platform 32 and close to one end of the driver 2 34, the transport cylinder 33 is located directly below the conveying module 24, the connecting module 63 is located at the lowest position inside the sliding groove 62, the connecting block 1 67 is close to the connecting block 2 610, the return spring 611 is not deformed, the compression spring 616 is not compressed, and the two adjacent extrusion blocks 617 are in contact with each other.

[0051] When working:

[0052] Picking and placing of PCB boards:

[0053] The operator places the PCB board on the upper surface of the conveying module 24, and then the operator electrically drives the driver 1 23 to start through the external controller. The driver 1 23 starts to drive the conveying module 24 to transmit inside the conveying table 22. At this time, the PCB board located on the upper surface of the conveying module 24 will move toward the end close to the transport cylinder 33 along with the transmission of the conveying module 24. When the PCB board moves to the bottom of the driver 2 34, the operator electrically controls the driver 2 34 to start through the external controller. The driver 2 34 starts to electrically drive the transport cylinder 33 to start. The start of the transport cylinder 33 relies on The PCB board is pneumatically sucked, and then the operator electrically controls the driver 2 34 to start through the external controller. The driver 2 34 starts to drive the transport cylinder 33 to slide on the outer surface of the transport platform 32 toward the end close to the inside of the detection box 1. At this time, the PCB board will enter the inside of the detection box 1 with the sliding of the transport cylinder 33. At this time, the operator electrically drives the electric telescopic rod 31 to extend through the external controller. The extension of the electric telescopic rod 31 drives the transport platform 32 to move toward the end close to the connecting rod 614. As the transport platform 32 moves, the PCB board will move between the two extrusion blocks 617.

[0054] PCB clamping:

[0055] In the above, the PCB board is smoothly guided into the interior of the detection box 1 by the movement of the transmission component 2 and the transportation component 3. In this process, a key step is to accurately place the edge of the PCB board between the two extrusion blocks 617. As the electric telescopic rod 31 and the transportation cylinder 33 move in coordination, the edge of the PCB board will gently squeeze the extrusion blocks 617 on both sides. After being squeezed, the two extrusion blocks 617 will slide toward the two ends close to the inner cavity surface of the adapter groove 615. As the extrusion blocks 617 move, the compression springs 616 are gradually compressed. The compression springs 616 are compressed to store elastic potential energy. At the same time, the extrusion blocks 617 tend to approach each other under the influence of the elastic force released by the compression springs 616. This tendency is to tightly clamp the edge of the PCB board to provide a stable clamping force, thereby achieving a stable clamping of the PCB board, ensuring that the extrusion blocks 617 can fit closely to the edge or specific position of the PCB board, effectively reducing the detection error caused by movement or offset, significantly improving the accuracy and reliability of the detection data, and providing a solid foundation for the subsequent detection of the PCB board.

[0056] Detection of the lateral and longitudinal movement of the body 52:

[0057] When the PCB board is clamped, the operator electrically controls the detection body 52 to start through the external drive device, and the detection body 52 starts to detect the surface of the PCB board. At this time, the operator can electrically control the driver three 43 to start through the external controller. The driver three 43 can electrically control the X-axis sliding module 42 to slide inside the X-axis limit frame 41. The sliding of the X-axis sliding module 42 drives the moving platform unit 45 to slide, and the sliding of the moving platform unit 45 drives the positioning frame 51 to slide. The sliding of the positioning frame 51 drives the detection body 52 to slide, thereby realizing the lateral movement of the detection body 52. ​​At the same time, the operator can electrically control the driver three 43 to start through the external controller. The driver three 43 can electrically control the moving platform unit 45 to slide on the upper surface of the Y-axis sliding rod 44, and the sliding of the moving platform unit 45 drives the positioning frame 51 to slide. The sliding of the positioning frame 51 drives the detection body 52 to slide, thereby realizing the longitudinal sliding of the detection body 52, and the lateral and longitudinal movement of the detection body 52, thereby realizing comprehensive detection of the PCB board.

[0058] Flipping of PCB board:

[0059] When the inspection of one side of the PCB board is completed, the operator electrically controls the connection module 63 to move upward inside the sliding groove 62 through the external controller, and the connection module 63 moves upward to drive the positioning block 64 to move upward, and the positioning block 64 moves upward to drive the rotating column 65 to move upward, and the rotating column 65 moves upward to drive the rotating disk 612 to move upward, and the rotating disk 612 moves upward to drive the connecting rod 614 to move upward, and the connecting rod 614 moves upward to drive the extrusion block 617 to move upward, and the extrusion block 617 moves upward to drive the PCB board to move upward. At the same time, the rotating disk 612 moves upward to drive the resistance column 613 to move upward. When the resistance column 613 moves upward, the resistance column 613 will conflict with the resistance rod of the resistance sliding frame 72. When the connection module 63 continues to move upward, the resistance column 613 is subjected to the resistance force, and the resistance column 613 drives the rotating disk 612 to rotate, and the rotating disk 612 rotates to drive the connecting rod 614 to rotate, and the connecting rod 614 rotates to drive the extrusion block 617 to rotate, and the extrusion block 617 rotates to drive the PCB board to rotate;

[0060] At the same time, the rotation of the rotating disk 612 drives the rotating column 65 to rotate, and the rotation of the rotating column 65 drives the linkage rod 66 to rotate with the center of the rotating column 65 as the axis, and the rotation of the linkage rod 66 drives the connecting block 1 67 to rotate. Since the connecting block 2 610 is fixedly connected to the connecting block 1 67 and the reset spring 611 respectively, the reset spring 611 does not rotate, and the rotation of the connecting block 1 67 changes the initial position of the connecting block 1 67, and the connecting block 1 67 will move away from the connecting block 2 610, and then the rotation of the connecting block 1 67 will drive the reset spring 611 to deform, that is, stretch. At this time, since the reset spring 611 is stretched, under the elastic contraction force of the reset spring 611, the rotating connecting block The first 67 is rotated again to fit with the second connection block 610, and the limiting posts 68 are set on both sides of the outer surface of the positioning block 64. The setting of the limiting posts 68 limits the rotation angle of the linkage rod 66, thereby allowing the connection block 1 67 to rotate 180 degrees, thereby realizing the 180-degree rotation of the linkage rod 66, and the 180-degree rotation of the linkage rod 66 drives the rotating post 65 to rotate 180 degrees, and the rotation of the rotating post 65 drives the rotating disk 612 to rotate 180 degrees. From the above, it can be seen that the rotation of the rotating disk 612 will affect the rotation of the PCB board, that is, the 180-degree rotation of the PCB board is realized. The automated process of flipping the PCB board reduces manual intervention and improves production efficiency.

[0061] When the PCB board is flipped, the operator electrically controls the connection module 63 to move downward in the sliding groove 62 through the external controller. The connection module 63 moves downward, driving the positioning block 64 to move downward. The positioning block 64 moves downward, driving the rotating column 65 to move downward. The rotating column 65 moves downward, driving the rotating disk 612 to move downward. The rotating disk 612 moves downward, driving the connecting rod 614 to move downward. The connecting rod 614 moves downward, driving the extruding block 617 to move downward. The extruding block 617 moves downward, driving the PCB board to move downward. The PCB board moves downward and returns to the initial position to be detected. In the process of the downward movement of the interference column 613, it will conflict with the inclined surface of the interference slider 73. As the interference column 613 descends, the interference slider 73 moves along the inclined surface it conflicts with. The movement of the interference slider 73 drives the interference slide frame 72 to slide between the two limit brackets 71, thereby preparing for the next interference flipping, thereby ensuring the continuity and smoothness of the flipping operation and improving the overall operation efficiency.
