Description

Technical Field

[0001] This invention relates to the field of PCB board processing, and in particular to a PCB board flipping device. Background Technology

[0002] PCBs, also known as printed circuit boards, are important electronic components. They serve as the support for electronic components and the carrier for their electrical interconnections. Due to their advantages such as high density, high reliability, designability, manufacturability, and maintainability, they are increasingly widely used. Existing flipping mechanisms cannot hold different types of PCBs, requiring the disassembly and replacement of different positioning and clamping devices. This entire replacement process is time-consuming, labor-intensive, and cumbersome.

[0003] To address this, a PCB flipping machine with an adjustable limiting structure was developed, such as patent number CN221688901U. While solving the aforementioned problems, this equipment has the following drawbacks: when fixing or disassembling a PCB board, it requires sequential adjustment of the first, second, and third lead screws, which is time-consuming and labor-intensive, and also seriously affects work efficiency. Furthermore, when fixing PCB boards with long front and rear sections, its mounting and fixing components can only fix the rear half of the PCB board, resulting in a large area of ​​the PCB board in front of the two sets of components being suspended in the air, which is not conducive to improving the safety and stability of the PCB board. Summary of the Invention

[0004] The purpose of this invention is to provide a PCB board flipping device.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A PCB board flipping device includes a bracket mounted on a base. A C-shaped plate driven by a motor is mounted on one side of the top of the bracket. A mounting plate is mounted at the open end of the C-shaped plate. Both horizontal ends of the C-shaped plate have strip-shaped openings to accommodate push rods. A screw rod is screwed onto the push rod, the end of which is fixed to the mounting plate by a bearing. A slide rod penetrating the mounting plate is also provided at the end of the push rod. A C-shaped rod with both ends penetrating its sidewall is provided on one side of the slide rod. Both ends of the C-shaped rod are connected to a strip seat. A spring is sleeved on the C-shaped rod between the strip seat and the slide rod. A slot is provided on one end face of the strip seat. An elastic clamping member with an Ω-shaped cross-section is provided on the outer side of the strip seat, one end of which extends into the slot. Elastic elements are provided between the upper and lower end faces of the clamping member and the sidewalls corresponding to the slot.

[0007] Preferably, the elastic element is made of rubber, and the upper and lower end faces of the elastic element are respectively bonded and fixed to the outer wall of the corresponding clamping member and the inner wall of the slot. The sealing end of the clamping member extends into the slot and is bonded and fixed to its corresponding inner wall.

[0008] Preferably, the push rod is provided with a screw hole for screwing with the screw rod, the end of the screw rod is provided with a protrusion, and the screw rod is provided on the push rod on the outside of the C-shaped plate.

[0009] Preferably, the mounting plate is provided with through holes that are adapted to the size of the slide rods, the slide rods pass through the corresponding through holes, and the U-shaped plate is located between the two sets of slide rods.

[0010] Preferably, the U-shaped plate and the strip seat are respectively disposed on both sides of the mounting plate, wherein the two sets of strip seats are located between the two sets of slide rods.

[0011] Preferably, the slide bar is provided with a sliding hole for the U-shaped rod to pass through.

[0012] The beneficial effects of this invention are: this invention facilitates the clamping and fixing of PCB boards, and also makes it convenient to remove the processed PCB boards. When encountering PCB boards with a long front and back length, by moving the strip seat forward, the clamping parts on the strip seat can clamp and fix the middle of both ends of the PCB board, reducing the suspended area at both ends and preventing the large area of ​​the front end of the PCB board from being suspended, which would lead to insufficient stability or affect its safety.

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] A PCB board flipping device includes a bracket 1 mounted on a base. A U-shaped plate 3 driven by a motor 2 is mounted on one side of the top of the bracket 1. A mounting plate 4 is mounted at the open end of the U-shaped plate 3. Both horizontal ends of the U-shaped plate 3 are provided with strip-shaped openings 5 ​​for accommodating push rods 6. A screw rod 7 is screwed onto the push rod 6, the end of which is fixed to the mounting plate 4 by a bearing. The push rod 6 is provided with a screw hole for screwing into the screw rod 7. A protrusion is provided at the end of the screw rod 7. The screw rod 7 is mounted on the push rod 6 on the outside of the U-shaped plate 3.

[0017] like Figure 1As shown, the end of the push rod 6 is provided with a slide rod 8 that passes through the mounting plate 4. One side of the slide rod 8 is provided with an incline rod 9 with both ends passing through sliding holes on its side wall. The two ends of the incline rod 9 are connected to the strip seat 10. A spring 11 is sleeved on the incline rod 9 between the strip seat 10 and the slide rod 8. A slot 12 is provided on one end face of the strip seat 10. An elastic clamping member 13 with one end extending into the slot 12 and having an Ω-shaped cross-section is provided on the outside of the strip seat 10. An elastic member 14 is provided between the upper and lower end faces of the clamping member 13 and the side wall corresponding to the slot 12.

[0018] In this embodiment, the elastic element 14 is made of rubber. The upper and lower end faces of the elastic element 14 are respectively bonded and fixed to the outer wall of the corresponding clamping member 13 and the inner wall of the slot 12. The sealing end of the clamping member 13 extends into the slot 12 and is bonded and fixed to its corresponding inner wall.

[0019] In this embodiment, the mounting plate 4 is provided with through holes that are adapted to the size of the slide rod 8. The slide rod 8 passes through the corresponding through holes, and the U-shaped plate 3 is located between the two sets of slide rods 8.

[0020] like Figure 1 As shown, the C-shaped plate 3 and the strip seat 10 are respectively arranged on both sides of the mounting plate 4, wherein the two sets of strip seats 10 are located between the two sets of slide rods 8.

[0021] The method of using this invention is as follows: By pulling the U-shaped rod 9 outward, its body slides outward within the sliding hole on the slide rod 8, thereby driving the two sets of strip seats 10 to move outward and simultaneously widening the distance between the two sets of strip seats 10. At this time, the strip seats 10 will compress the spring 11. Then, the PCB board is placed between the two sets of clamping members 13. When the U-shaped rod 9 is slowly released, the strip seats 10 are pushed by the stretching force of the spring 11, thereby narrowing the distance between the two sets of strip seats 10. When the strip seats 10 drive the clamping members... After component 13 moves to a certain position, it will cause the open end of clamping component 13 to lock onto the corresponding end of the PCB board. Then, as the end of the PCB board slides into the clamping component 13, it will open the opening of the clamping component 13. At the same time as the opening of the clamping component 13 opens, it will compress the corresponding elastic component 14. When the end of the PCB board slides into the opening of the clamping component 13, the elastic component 14 expands and the side wall of the opening end of the clamping component 13 contracts and rebounds, so that the above components can lock and fix the end of the PCB board well.

[0022] The motor 2 drives the C-shaped plate 3 to rotate the mounting plate 4, push rod 6, slide rod 8, C-shaped rod 9, and strip seat 10, thereby causing the PCB board fixed by the clamping member 13 to perform end face flipping, so as to achieve the purpose of flipping the PCB board. When encountering a batch of PCB boards with long front and rear lengths, multiple sets of screws 7 are rotated simultaneously in the same direction and at the same speed, so that they rotate in the corresponding screw holes and bearings. This pushes the two ends of the push rod 6 to move forward at the same speed in the sliding opening 5. At the same time, the push rod 6 also drives the slide rod 8 to move forward in the through hole on the mounting plate 4. At this time, the forward-moving slide rod 8 drives the strip seat 10 and clamping member 13 to move forward through the C-shaped rod 9. When the PCB board is fixed by the strip seat 10, the clamping member 13 on the strip seat 10 can clamp and fix the middle part between the front and rear ends of the PCB board, reducing the suspended area of ​​the PCB board at the front and rear ends, and preventing the front end of the PCB board from being suspended in a large area, which would lead to insufficient stability or affect its safety.

[0023] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
