the circuit board is contacted with the conveying unit after entering one end of the clamping groove, the circuit board is conveyed into the clamping area by the conveying unit, the movable clamp of the lower side linkage clamp in the clamping area is driven by the reversing assembly to approach the circuit board to clamp and fix the circuit board, meanwhile, the linkage clamp at the upper side is driven by the clamp moving device to adjust the approach of the linkage clamp to the circuit board, when the linkage clamp moves to a position where the fixed clamp is attached to one side of the circuit board, starting the reversing component, the connecting pin in the reversing component slides relative to the connecting groove in the moving process of the transmission plate, so that the movable clamp approaches to the fixed clamp, so as to clamp and fix the upper side of the circuit board, thereby completing the fixation of the upper side and the lower side of the circuit board in the horizontal direction, and adjusting the positions of the clamping handles of the clamping jaws and the circuit board according to the actual requirement of the circuit board to complete the fixation of the two sides of the circuit board in the vertical direction.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
