Utility Model Content

[0005] The purpose of this utility model is to provide a fixing fixture for PCB bracket processing, so as to solve the technical problem in the prior art that when the fixture clamps the two sides of the PCB, improper operation by the operator causes friction between the two sides of the PCB and the fixture, which leads to scratches at the connection between the two sides of the PCB and the fixture, and may even damage the two sides of the PCB, thereby affecting the fixing effect of the fixture on the PCB.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0016] The beneficial effects of this utility model are:

[0017] 1. Place both sides of the PCB on the pads fixed to the inner wall of the clamping plate. The pads are plastic. Then, the slide slides on the inner wall of the slide groove.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-7 As shown, a fixing fixture for PCB bracket processing includes: a worktable 1, a vertical plate 7, and a clamping plate 9.

[0030] The workbench 1 has a slide groove 6 along its length. Two sets of slide blocks 3 are fitted and slidably connected to the inner wall of the slide groove 6. The bottom end of the vertical plate 7 is fixedly connected to the slide blocks 3. A tilting mechanism 8 is fixedly connected to the side end of the vertical plate 7. A rotating hole is formed through the vertical plate 7, and a rotating shaft 14 is rotatably connected to the inner wall of the rotating hole. The side end of the rotating shaft 14 is fixedly connected to the tilting mechanism 8. The side end of the clamping plate 9 is fixedly connected to the rotating shaft 14. A telescopic actuator 10 is fixedly connected to the top of the clamping plate 9. A pad 17 is fixedly connected to the inner wall of the clamping plate 9. A positioning hole is formed through the pad 17 at the top of the clamping plate 9. A telescopic rod 15 is fixedly connected to the bottom end of the telescopic actuator 10. The telescopic rod 15 is slidably connected to the positioning hole. A support seat 16 is fixedly connected to the bottom end of the telescopic rod 15. The PCB is placed on the pads 17 fixed to the inner wall of the clamping plate 9 on both sides. The pads 17 are plastic. Then the slide 3 slides on the inner wall of the slide groove 6. The slide 3 moves the flipping machine 8 and the rotating shaft 14 through the vertical plate 7. The rotating shaft 14 and the clamping plate 9 support the two sides of the PCB. At this time, the telescopic driver 10 is running. The telescopic driver 10 drives the telescopic rod 15 to move the support seat 16 downward. The support seat 16 supports the top of the two sides of the PCB, thereby preventing the PCB from warping during processing. The pads 17 and the support seat 16 are both plastic, which can protect the two sides of the PCB and prevent scratches on the two sides of the PCB caused by improper operation by the staff.

[0031] When PCB processing requires flipping, the flipping machine 8 operates, and the flipping machine 8 drives the rotating shaft 14 to rotate in the rotating hole. The rotating shaft 14 carries the clamping plate 9 to rotate, thereby achieving the effect of flipping the PCB. The sliding block 3 and the inner wall of the slide groove 6 are locked together to ensure that the sliding block 3 has stability on the inner wall of the slide groove 6, avoiding the phenomenon of the sliding block 3 shifting and overturning, and ensuring that the sliding block 3 provides stable support for the vertical plate 7.

[0032] In some specific implementations, both sets of slides 3 are provided with threaded holes 12, and the threaded holes 12 of the two sets of slides 3 are in opposite directions. A threaded rod 4 is threadedly connected to the inner wall of the threaded hole 12. A servo motor 5 is fixedly connected to the side end of the threaded rod 4. The end of the threaded rod 4 away from the servo motor 5 is rotatably connected to the inner wall of the slide groove 6. In order to ensure that the clamping plate 9 can clamp both sides of PCBs of different sizes, the servo motor 5 is running. The servo motor 5 drives the threaded rod 4 to rotate. Since the threaded holes 12 are in opposite directions, the threaded rod 4 drives the two sets of slides 3 to move in opposite or the same direction through the threaded connection with the threaded hole 12, so as to support and fix PCBs of different sizes.

[0033] In some specific implementations, a rangefinder 13 is fixedly connected to the side of the vertical plate 7. In order to ensure that the clamping plate 9 accurately supports and fixes both sides of the PCB, when the slide 3 moves with the vertical plate 7, the rangefinder 13 fixed to the side of the vertical plate 7 can perform laser distance measurement on the distance between the two sets of clamping plates 9.

[0034] In some specific implementations, a support base 11 is provided between the two sets of clamping plates 9. The top end of the support base 11 is at the same horizontal plane as the bottom end of the pad 17. A support frame 2 is provided at the bottom of the support base 11. The two ends of the support frame 2 are fixedly connected to the inner wall of the slide 6. A hinge seat 20 is fixedly connected to the top end of the support frame 2. A hinge plate 21 is hinged to the inner wall of the hinge seat 20. The hinge plate 21 is located at the center of the bottom of the support base 11 and is fixedly connected to the support base 11. When the PCB is subjected to force during processing, only the two sides of the PCB are supported by the clamping plates 9, and the center of the PCB does not receive support. To avoid the center of the PCB being subjected to force... The impact force caused damage to both sides of the PCB. The support seat 11 is located at the bottom center of the PCB. The support seat 11 can support the PCB and buffer the impact force on the PCB. The support seat 11 is plastic, which can prevent wear between the support seat 11 and the PCB. When the clamping plate 9 flips the PCB, the support seat 11 flips synchronously with the clamping plate 9. When the support seat 11 rotates, the support seat 11 and the hinge plate 21 rotate along the inner wall of the hinge seat 20. The support frame 2 provides support for the support seat 11 through the hinge connection between the hinge seat 20 and the hinge plate 21.

[0035] In some specific implementations, a transfer plate 22 is fixedly connected to both ends of the support base 11, and a connecting rod 19 is fixedly connected to the side end of the transfer plate 22. A connecting seat 18 is fixedly connected to both ends of the clamping plate 9. The connecting seat 18 is located at the bottom of the clamping plate 9 and has a limit hole. The connecting rod 19 is slidably connected to the inner wall of the limit hole. In order to realize that the clamping plate 9 drives the support base 11 to rotate synchronously, when the clamping plate 9 rotates, the connecting seat 18 fixed to the clamping plate 9 rotates. The connecting seat 18 is supported by the limit hole and the inner wall of the connecting rod 19, thereby transmitting the rotation action to the support base 11 through the transfer plate 22, thereby driving the support base 11 to rotate synchronously. When the clamping plate 9 moves, the inner wall of the limit hole slides along the connecting rod 19. The connecting rod 19 realizes the function of transmitting the rotation action of the clamping plate 9.

[0036] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
