Abstract
Description
[Technical Field]
[0001] This invention relates to a warehouse-type automatic board feeding device and a multilayer board pre-stacking machine, and more particularly to a design that automatically and correctly feeds boards to avoid errors in multilayer board pre-stacking. [Previous Technology]
[0002] Note that circuit boards typically consist of multiple layers, such as stacked PP sheets and core boards. The production process of circuit boards requires pre-stacking of the PP sheets and core boards before pressing. The pre-stacking process is usually done manually. During the pre-stacking process, workers need to pick up and place each layer of boards in the order of the layers. Each layer of boards is stacked on different shelves on different trolleys or shelves. If the workers are negligent, it is easy to pick up the wrong boards, resulting in an error in the order of the pre-stacked layers and the occurrence of scrap boards. The higher the number of layers in the pre-stacking, the higher the error rate. [Summary of the Invention]

The storage box drive power unit 32 is provided with a transmission wheel 321 on each of the pair of storage box drive screws 31, and a storage box lifting motor 322 and several idler wheels 323 are provided on the frame 10. The drive shaft of the storage box lifting motor 322 is provided with a drive wheel 324, and a transmission belt 325 is wound around the transmission wheels 321, the idler wheels 323 and the drive wheel 324. A drawer opening and closing drive unit 40 is provided, with a pair of forward and backward power sources 41 on both sides of the frame 10, and a pair of drawer drive power groups (the drawer drive power group is a combination of a drawer opening and closing motor 421 and a gear set 422) at the actuating end of the pair of forward and backward power sources 41. The pair of forward and backward power sources 41 control the power connection state between the pair of drawer drive power groups and the pair of gear racks 221. The pair of forward and backward power sources 41 can be pneumatic cylinders. When the pair of forward and backward power sources 41 are pushed forward, the gear set 422 and the gear rack 221 are engaged. When the pair of forward and backward power sources 41 are pulled back, the gear set 422 and the gear rack 221 are not engaged. The gear set 422 will not interfere with the lifting and lowering of the storage box 20. A human-machine interface 50 is provided on the frame 10 to input and control the operation program of the storage box lifting drive unit 30 and the drawer opening and closing drive unit 40.
[0012] The automatic pallet feeding device of the present invention further includes a drawer locking unit 60. The drawer locking unit 60 is provided with a pair of unlocking power sources 61 on both sides of the frame 10, and a pair of drawer locking groups 62 on both sides of each drawer 22. The pair of drawer locking groups 62 normally locks the pair of toothed racks 221 to keep each drawer in a closed state.
