AI Technical Summary
Existing corner-cutting fixtures cannot rotate the workpiece, requiring re-clamping when adjusting the corner position. Furthermore, they cannot fix the circuit board left and right, making it prone to displacement during the corner-cutting process and affecting the quality of the circuit board.
A corner-cutting fixture was designed, comprising a left clamping plate, a right clamping plate, a front-to-back moving device, a lateral moving device, and a pressing device. The clamping plate is moved by a lead screw driven by a servo motor to achieve stable fixation of the circuit board, and the mounting plate is rotated by a drive device to adjust the corner-cutting position.
This achieves stable fixation of the circuit board, avoids offset during the corner cutting process, improves corner cutting accuracy and work efficiency, and reduces repetitive clamping work.
