Description

Variable-pitch grabbing mechanism for simultaneously grabbing multiple products

Technical Field

The utility model relates to a variable-pitch grabbing mechanism for grabbing a plurality of products simultaneously.

Background

At present, in the laser processing industry, occasions with full-automatic feeding and discharging requirements are frequently met. When the small products are fed by the plastic sucking tray, the products are required to be carried to a processing carrier by a material taking mechanism, and then are subjected to engraving, corrosion, cutting, repairing and other processing by a vibrating mirror and a field lens of a laser.

In the semiconductor industry, the requirements on intelligent equipment are higher and higher, most of the semiconductor equipment is manually taken and placed, then a door is manually closed, a start key is pressed, and the equipment starts to be automatically processed. The mode of once grabbing 4pcs products can only grab each piece and can finish the process after four grabbing processes; if the four-sucker equidistant product grabbing mode is designed, the product interval of the carrier is different from the product interval of the incoming tray, so that each piece can be grabbed only, and the situation that an expensive laser processing area waits for loading and unloading is caused, so that cost is wasted. The traditional material taking mechanism has the advantages of low efficiency, low yield and large space waste when grabbing each piece.
