Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automatic product loading and unloading mechanism. Background Technology

[0002] In the automated production of various electronic components, electronic components are placed on trays. Loading involves retrieving components from the trays, while unloading involves placing the processed electronic components onto the trays. Currently, some feeding devices only have one loading / unloading station, and all loading and unloading are done through this single station. Each time, the loading / unloading trolley must return the empty tray to the storage bin before a new tray with components can be retrieved and delivered to the same station for the next step of processing. Tray buffering or alternation is not possible, or manual loading and unloading is required during the transfer process. Furthermore, the loading / unloading trolley will be idle for a portion of the subsequent processing time, resulting in resource waste and low overall loading / unloading efficiency, which in turn leads to low overall processing efficiency of the automated equipment.

The fourth drive cylinder 886 is started, and the fourth drive cylinder 886 drives the movable pull plate 883 to move, thereby driving the elastic clamping member 94 to extend and retract. The workpiece is released from the clamping and fixing of the elastic clamping member 94, which facilitates the second picking robot 62 to pick up the workpiece.

[0064] It should be noted that in this invention, the feeding device, the picking device 60, the cutting device 70, the product conveying line 80, and the feeding fixture 90 are all equipped with position sensors.
