A plate suction robot

By using a linear module to drive the aluminum profile to adjust the suction cup distance, and by setting up an independent air extraction network and clamping mechanism, the problem of vacuum leakage and board drop in traditional board picking devices on PCBs with multiple through holes and heavy weights is solved, achieving stable picking and preventing board drop.

AI Technical Summary

Technical Problem

Traditional board pick-up devices suffer from large vacuum leakage when dealing with PCBs with multiple through holes and heavy weights, resulting in insufficient suction force and easy board dropping. Furthermore, it is difficult to adjust the suction cup distance to accommodate boards of different sizes.

Method used

A board-picking robot was designed, which uses a linear module to drive the aluminum profile to adjust the distance of the suction cups. An independent air extraction network and edge clamping mechanism are set up to ensure that each set of suction cups has an independent vacuum source, and the edges of the board are clamped by pneumatic grippers to prevent the board from falling off.

Benefits of technology

It achieves stable pick-up on PCBs with multiple through holes and heavy weight, reduces fluctuations in pick-up force, prevents boards from falling off, and adapts to the needs of boards of different sizes.

Abstract

This utility model relates to a sheet metal suction robot, comprising a linear module, an aluminum profile I mounted on the slider of the linear module, two sets of clamping mechanisms I mounted in the middle of the aluminum profile I, a profile support mounted at the tail of the linear module, an aluminum profile II mounted at the bottom of the tail of the profile support, and a set of clamping mechanisms II mounted in the middle of the aluminum profile II. Multiple suction cup sets are mounted on both aluminum profile I and aluminum profile II, and each suction cup set is connected to the vacuum port of a vacuum generator through a set of suction pipes. The advantages are: since each suction cup set is connected to the vacuum port of a vacuum generator through a set of suction pipes, even if some suction cup sets have through holes at their suction positions on the sheet metal, it will not affect the normal suction of the sheet metal by other suction cup sets; the clamping mechanisms I and II clamp the edges of the sheet metal during handling to prevent the sheet metal from falling off due to its weight or vibration during handling.
