In the production of smart watch PCBA boards In the operation of producing the patch, since the smart watch PCBA board has been fixed, the smart watch PCBA board is then pressed, and a plurality of sleeve cylinders 405, patch pressing blocks 406 and patch placement blocks 409 are provided. The materials that need the patch are placed inside the patch placement block 409, and then under the action of the horizontal pusher 403, the connecting horizontal plate 404 can be driven to move, and the sleeve moving plate 408 plays a telescopic role. The sleeve cylinder 405, patch pressing block 406 and patch placement block 409 at the bottom of the fixed connecting plate 402, and the sleeve cylinder 405, patch pressing block 406 and patch placement block 409 at the bottom of the connecting horizontal plate 404 can all move relatively, and patches can be pressed at different positions.It can deliver materials to precise positions for patching. When the designated position is reached, downward pressure is applied to the fixed connecting plate 402 through the telescopic hydraulic cylinder C401. At the same time, the fixed connecting plate 402 and the lateral pusher 403 are fixedly connected to the connecting horizontal plate 404. The bottom surface of the connecting horizontal plate 404 also has downward pressure. The sleeve cylinder 405 at the bottom of the connecting horizontal plate 404 and the fixed connecting plate 402 drives the patch pressing block 406 to move downward to complete the material patching operation of the smart watch PCBA board. When in use, it can be fixed in multiple positions, and can be fixed for smart watch PCBA boards of different specifications and shapes.
