Detailed Description

As shown in fig. 1, the present embodiment provides a clamping mechanism for a PCB board, which includes two sets of symmetrically arranged clamping structures 2.

Specifically, each clamping structure 2 comprises a chain 21, two first gears 22, a second gear 23 and a plurality of clamping pieces 24, the two first gears 22 are located inside two ends of the chain 21, the second gear 23 is located outside the chain 21, the first gears 22 and the second gears 23 are in meshing fit, the two second gears 23 are in meshing fit, a motor 25 is arranged at the top of one of the gears, and the clamping pieces 24 are fixedly connected to the bottom of the chain 21 and used for clamping the PCB in a vertical state.

More specifically, the motor 25 is fixedly connected to the support plate 1, an output shaft of the motor 25 is connected to one of the second gears 23, the other second gear 23 is movably connected to the support plate 1, the second gear 23 is in rotating fit with the support plate 1, and the first gear 22 is fixedly connected to the support plate 1 through the arched rod 221.

More specifically, as shown in fig. 3, in this embodiment, the bottom of each chain 21 is provided with 18 clamping members 24, 9 clamping members 24 on two sides of the chain 21 are respectively corresponding to the clamping members 24 on two sides of the central axis of the clamping mechanism, and the two corresponding clamping members 24 are in a group and used for clamping the same PCB, so that there are 9 groups of clamping members 24 on the innermost side, which can clamp 9 PCBs, and when the clamping member 24 on the outer side moves to the innermost side, 9 groups of clamping members 24 can be formed.

More specifically, as shown in fig. 2, each clamping member 24 includes a lifting rod 241 and two flexible clamping jaws 242, a power source of the lifting rod 241 may be an air cylinder, etc., the top of the lifting rod 241 is connected to the chain 21, the lifting rod 241 is used for regulating and controlling the lifting of the flexible clamping jaws 242, the two flexible clamping jaws 242 clamp the PCB board in an inflation or deflation manner, and when the flexible clamping jaws 242 are in a natural state, the two flexible clamping jaws 242 are kept vertical with a certain interval in between; when the flexible clamping jaws 242 are in an inflated state, due to gas expansion, the two flexible clamping jaws 242 are bent, the middle portions of the two flexible clamping jaws are convex, the bottom ends of the two flexible clamping jaws are close to each other, so that the PCB is firmly fixed, and meanwhile, the PCB cannot be damaged due to clamping acting force.

In the above manner, when the clamping member 24 moves to the preset position, that is, above the PCB, the lifting rod 241 descends to move the two flexible clamping jaws 242 down to the preset position, and then the flexible clamping jaws 242 start to inflate to clamp the PCB; because the chains 21, the first gear 22, the second gear 23 are meshed and matched in the same clamping mechanism 2, and the two second gears 23 are also meshed and matched, after one of the second gears 23 is driven by the motor 25 to rotate clockwise, the two chains 21 start to rotate anticlockwise, and the clamping piece 24 located at the innermost side sequentially moves from one end of the clamping mechanism to the other end.

In summary, the flexible clamping jaw is used for clamping the PCB, so as to prevent the PCB from being damaged by the clamping force; in addition, through the meshing fit of the chain 21, the first gear 22 and the second gear 23, the present embodiment can clamp a plurality of PCB boards at one time for transfer, or clamp one PCB board after another from one end point for transfer, thereby greatly improving the transfer rate of the PCB boards.
