Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a PCBA board splitting device based on machine vision. Background Art

[0002] The PCBA board is a key electronic component used to support and connect electronic components to form a complete functional circuit. It plays an important role in electronic manufacturing, and the quality of its design and manufacturing directly affects the performance and reliability of electronic products. And the PCBA board needs to be split during the production and processing process.

[0003] After retrieval, a Chinese patent with the publication number of CN216760055U discloses a PCBA multi-connected board splitting device, which relates to the field of circuit board production. Aiming at the problems that the existing device causes the board material to deform or damage the PCBA electrical circuit, components, and tin tracks due to uneven force of manual folding and differences in the folding angle position, and it is also unable to split the PCBA board with multiple modules combined together, the following solution is proposed. It includes a housing, a pushing mechanism, and a clamping mechanism. A bracket is installed on the housing, and a sliding groove is opened on one side of the bracket. The structure of the utility model is novel. The PCBA multi-connected board is split by a cutting machine, effectively avoiding the problems of uneven force and differences in the folding angle position caused by manual splitting, resulting in board material deformation or damage to the PCBA electrical circuit, components, and tin tracks. At the same time, it can split the PCBA board with multiple modules combined.

[0004] The above patent mentions in the specification that "the PCBA board 8 to be split is clamped on the clamping mechanism 5 by the clamping plate 503. The clamping plate 503 only clamps the edge of the PCBA board 8. The pushing mechanism 4 pushes the clamping mechanism 5 forward through the telescopic rod 401, and the clamping plate 503 moves along the limiting groove 502." Although the above patent can clamp the PCBA board, it can only limit and fix the PCBA board with the same length and style, resulting in ineffective processing when facing different PCBA boards, thus reducing the flexibility of the device.

[0026] Refer to Figure 1 and Figure 4The through holes on both sides of the support platform 10 are slidably connected with sliding columns 11, and the outer sleeve of the sliding column 11 is provided with a spring 12. The bottom of the sliding column 11 is fixedly connected with a support frame 13. One end of the spring 12 is fixedly connected to one side of the support platform 10, and the other end of the spring 12 is fixedly connected to one side of the support frame 13. The sliding column 11 is pushed to move by the support frame 13 so that the spring 12 can be squeezed and deformed. The inner walls on both sides of the support frame 13 are rotatably connected with limiting rods 14. The outer coupling of the two limiting rods 14 is connected with limiting belts 15, and the plate is restricted by the limiting belts 15. Restriction, the outside of the limiting belt 15 contacts the inner wall of the support frame 13, the top of the sliding column 11 is fixedly connected to the limiting block 16, the bottom of the limiting block 16 contacts the top of the support platform 10, and the sliding column 11 is restricted by the limiting block 16 to prevent the sliding column 11 from falling.

[0027] The disassembly assembly includes two control rods 20, which are slidably connected to the two sides of the support platform 10 respectively. Under the sliding of the control rods 20, the disassembly of the cutting head 17 can be controlled. The far sides of the two control rods 20 are fixedly connected with pulling blocks, and the control rods 20 are convenient to pull through the pulling blocks. The outside of the control rods 20 is provided with a slot hole 21, and the inner wall of the slot hole 21 is engaged with the inner wall of the special-shaped block 19, so that the cutting head 17 is fixed. The left end of the control rod 20 is fixedly connected with a pushing plate 22, and when the control rod 20 moves, the pushing plate 22 can be moved with it. The outside of the pushing plate 22 is slidably connected to the inner wall of the support platform 10. The left and right sides of the control rod 20 are provided with a spring 23, one end of the spring 23 is fixedly connected to one side of the pushing plate 22, and the other end of the spring 23 is fixedly connected to the inner wall of one side of the support platform 10.

Table legs are fixedly connected to the four corners of the bottom of the housing 1.

[0028] Working principle: When the device needs to be used, place the plate to be cut on the top of the conveyor belt 24 for transportation. When the plate reaches the appropriate position, start the hydraulic cylinder 9. Under the activation of the hydraulic cylinder 9, it will drive the support platform 10 to lift and lower. Through the lifting and lowering of the support platform 10, it can push the sliding column 11 to drive the support frame 13 to descend. At this time, during the continuous descent process, the limiting belt 15 will first contact the top surface of the plate. After the limiting belt 15 abuts against the plate, it will push the support frame 13, causing the support frame 13 to push the sliding column 11 to slide at the through hole of the support platform 10. At this time, the first spring 12 will be compressed and deformed to generate elastic potential energy. Through the elastic potential energy of the first spring 12, it can push the support frame 13 to make the limiting belt 15 tightly adhere to the plate, improving the limiting effect of the limiting belt 15 on the plate. Then, cut the plate with the cutting head 17. During the cutting process, start the motor 6. Under the activation of the motor 6, it will drive the threaded rod 7 to rotate, and the rotation of the threaded rod 7 can make the threaded block 8 move. Thus, under the movement of the threaded block 8, it can drive the hydraulic cylinder 9 to move, so that the cutting head 17 moves to cut the plate. At this time, under the movement of the cutting head 17, the limiting belt 15 will also move to limit the plate. When it is necessary to repair and replace the cutting head 17, slide the sliding block 4 at the bottom of the electric slide rail 3 to bring the cutting head 17 close to the side of the housing 1. At this time, pull the control rod 20. Under the pulling of the control rod 20, the slot hole 21 will move. When it moves to the appropriate position, the special-shaped block 19 can pass through the inner wall of the slot hole 21, so as to disassemble the cutting head 17 for maintenance. When installation is required, pull the control rod 20. The pulling of the control rod 20 will drive the push plate 22 to push the second spring 23. At this time, insert the special-shaped block 19 into the bottom of the support platform 10 and pass through the inner wall of the slot hole 21. Then release the control rod 20. The elastic potential energy stored in the second spring 23 will push the push plate 22 to drive the control rod 20 to reset, so that the slot hole 21 and the special-shaped block 19 are engaged to complete the installation.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
