Technical Field

The utility model relates to a conveyer's technical field specifically is an automatic feeding device.

Background

A plurality of processes are involved in the production and processing processes of the notebook computer, the most indispensable process in the plurality of processes is a feeding process, and the workpieces are fed to realize the subsequent corresponding processing of the workpieces. For smaller workpieces, multiple workpieces are typically placed on the same fixture or fixture, such as a long spindle, a spindle cover, a key, etc. in a notebook. Traditional material loading process is artifical material loading, moves anchor clamps or tool to the assigned position through the manual work, adds man-hour, places the processing station with the work piece through the manual work on, processes the work piece on a pair of anchor clamps or tool one by one, treats that the whole back that finish of processing of work piece on anchor clamps or the tool moves out empty anchor clamps or tool through the manual work.

However, the adoption of such a feeding mode has a great disadvantage: the reciprocating transportation of the clamp or the jig and the taking and placing of the clamp or the jig from the designated position all need to be operated manually, and the efficiency is low. Meanwhile, the feeding of the workpieces also needs to be manually operated, and the workpieces need to be accurately placed at a processing station to accurately process the workpieces, so that the time spent on a single workpiece when the workpieces are manually placed is long, the workload is large, the labor cost is high, and the efficiency is low.
