Description

Technical Field

[0001] The utility model relates to the field of loading and unloading equipment, in particular to a tray loading and unloading system. Background Art

[0002] The material tray is an auxiliary equipment used in automatic assembly machinery, which is used to arrange products in an orderly manner so that the automatic assembly machinery can perform assembly operations or the automatic inspection machinery can perform inspection operations. For example, on the inspection production line of the battery cell, the loading end of the loading and unloading equipment will lift the material tray containing the product layer by layer so that the subsequent manipulator can grab the product, and the empty tray will be collected and unloaded from the unloading end. The loading and unloading equipment is often used in conjunction with the AGV trolley. The AGV trolley transports the vertically stacked material trays to the loading end, and the loading end lifts the material tray on the AGV trolley and loads it. However, the products in the current batch of material trays have not been taken out, and the AGV trolley has transported a new batch of material trays to the loading end. At this time, the AGV trolley needs to wait temporarily, waiting for the loading end to complete the loading of the previous batch of products. It can be seen that the long standby time of the AGV trolley will obviously reduce the actual use time of the AGV trolley, resulting in an increase in the number of AGV trolleys purchased, and the manufacturing cost will also increase accordingly. Therefore, it is necessary to produce a material tray loading and unloading system to solve the above-mentioned problems. Utility Model Content
