Description

Technical Field

[0001] This utility model relates to the field of automatic loading and unloading technology, and in particular to a loading and unloading tray device for laser engraving equipment. Background Technology

[0002] During the mass production of PLC modules, laser engraving (such as QR codes, logos, characters, and patterns) is required on their outer casing to achieve traceability and brand recognition. On existing production lines, trays typically handle batch loading, turnover, and positioning, but they generally have the following shortcomings: 1) The loading / unloading path does not form a closed loop, and empty material trays often rely on manual recycling and return, increasing the risk of line stoppage and tray mixing; 2) Using only simple side stops or limiting posts for positioning, a stable benchmark cannot be established at the corner of the material tray, resulting in insufficient repeatability of laser engraving station positioning accuracy and fluctuation in yield. 3) The loading and unloading mechanisms are on the same line or in the same area, occupying a large space and interfering with each other, which affects the production cycle. Utility Model Content
