AI Technical Summary
During transformer production, excessive impact force caused by the contact between the needle and the workpiece surface during multi-station dispensing can lead to dispensing position deviation and workpiece tipping, resulting in wear of the needle and mechanical parts. At the same time, the workpiece is prone to falling off the worktable.
The device employs a buffer assembly and a fixing assembly. The buffer assembly uses a spring to buffer the contact pressure between the needle and the workpiece, while the fixing assembly uses a clamp and a positioning template to fix the workpiece, thus preventing excessive impact and workpiece movement.
It effectively avoids dispensing position deviation and workpiece tilting, reduces wear on needles and mechanical parts, improves dispensing accuracy and workpiece fixation stability, and enhances the reliability of multi-station dispensing.
