[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] This embodiment describes the specific structure of a PCB board riveting and clamping device. See details below. Figures 1-5 As shown, a PCB board rivet clamping device includes:

[0026] Lifting mechanism 1, the lifting mechanism 1 drives the lead screw to rotate by the motor, the lead screw drives the sliding block to move up and down, the sliding block drives the connecting block 2 to lift up and down, the bottom of the connecting block 2 is fixed with a connecting frame 3, and the bottom sides of the connecting frame 3 are provided with clamping mechanisms that can clamp the PCB board.

[0027] The auxiliary mechanism is located at the bottom of the connecting plate 5 and is used to cooperate with the clamping mechanism to clamp the PCB board.

[0028] Currently, after PCBs are riveted together by a riveting machine, they are usually transported to the next workstation by traditional manual handling. Prolonged handling can lead to decreased physical strength among workers, reducing efficiency. It can also cause misalignment between the transported and stacked PCBs, potentially resulting in the collapse of stacked PCBs, damage upon contact with the ground, and the generation of waste.

[0029] When it is necessary to clamp the PCB board, the clamping mechanism includes two symmetrically arranged electric push rods 7. The two electric push rods 7 are respectively fixed on both sides of the bottom of the connecting frame 3. The output end of the electric push rod 7 is fixed with a connecting plate 5. The top of the connecting plate 5 is slidably connected to the bottom of the connecting frame 3 through a sliding groove. The bottom of the two connecting plates 5 is fixed with a fixing rod 4. The opposing surfaces of the two fixing rods 4 are fixed with a fixing plate 8. The bottom of the fixing plate 8 is fixed with an L-shaped plate 9. The electric push rod 7 can drive the connecting plate 5 to slide at the bottom of the connecting frame. The connecting plate 5 drives the L-shaped plate 9 to move through the fixing block. The L-shaped plate 9 can clamp the PCB board after riveting.

[0030] Furthermore, a cylinder 12 is fixed on the fixed plate 8, and a pressure block 11 is fixed to the output end of the cylinder 12. An anti-slip pad is fixed to the bottom of the pressure block 11. The cylinder 12 drives the pressure block 11 to move downward, and the pressure block 11, together with the L-shaped plate 9, clamps the PCB board.

[0031] In addition, the L-shaped plate 9 has a slot 10 that can accommodate rivets, so that the slot 10 on the L-shaped plate 9 can be aligned with the rivet for insertion, thereby limiting the rivet and thus limiting the PCB board.

[0032] While the clamping mechanism clamps the PCB board, the auxiliary mechanism includes a hydraulic rod 6 fixed to the bottom of the connecting frame 3. A top plate 15 is fixed to the output end of the hydraulic rod 6. The hydraulic rod 6 drives the top plate 15 to move downward, facilitating the re-clamping of the PCB board with the L-shaped plate 9, thus improving the stability of the PCB board when clamped. A guide post 17 runs through the top plate 15. A baffle 13 is fixed to the top of the guide post 17, and a bottom plate 14 is fixed to the bottom of the guide post 17. A spring 16 is sleeved on the outside of the guide post 17 between the top plate 15 and the bottom plate 14. The top plate 15 drives the bottom plate 14 to move downward. The bottom plate 14 will contact the PCB board first, and the bottom plate 14 will drive the guide post 17 to slide on the top plate 15. At the same time, the top plate 15 and the bottom plate 14 compress the spring 16. The spring 16 gives the bottom plate 14 a reverse force, preventing the bottom plate 14 from putting too much pressure on the PCB board and causing damage.

[0033] It is worth noting that a soft pad 18 is fixed to the bottom of the base plate 14. The size of the soft pad 18 is the same as that of the base plate 14 to prevent the base plate 14 from making hard contact with the PCB board and causing damage to the PCB board.

[0034] During operation, when the PCB board needs to be moved, first control the electric push rod 7 to move the two fixed rods 4 in opposite directions. Then control the lifting mechanism 1 to move the fixed rods 4 to the same height as the PCB board, so that the L-shaped plate 9 is lower than the PCB board. Then control the electric push rod 7 to move the fixed rods 4 inward, so that the rivets are inserted into the slots 10 on the L-shaped plate 9, thereby clamping and limiting the PCB board. Finally, control the cylinder 12 to drive the clamping block to clamp the top of the PCB board, preventing the PCB board from moving up and down. The hydraulic rod 6 is controlled to move the top plate 15 downward, which in turn moves the bottom plate 14 downward. The bottom plate 14 will first contact the PCB board, and then the bottom plate 14 will drive the guide column 17 to slide on the top plate 15. At the same time, the top plate 15 and the bottom plate 14 work together to compress the spring 16. The spring 16 gives the bottom plate 14 a reverse force, which, together with the clamping mechanism, better clamps the PCB board. Then, the lifting mechanism 1 is controlled to move upward, and the device is moved to the designated position by the mobile device. The PCB board can be lowered by reversing the operation.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
