Description

Automatic storage system for electronic device trays

Technical Field

The application relates to the technical field of electronic device storage, in particular to an automatic storage system for an electronic device tray.

Background

Traditional electronic product manufacturers, electronic device trays are usually managed by warehouse material personnel, and when material is taken or fed, personnel are required to take and place on the shelf of the electronic device tray. After the electronic device warehouse is introduced into the warehouse management system, the electronic device warehouse is in butt joint with the electronic device tray automatic material cabinet, and the electronic device tray automatic material cabinet automatically completes the material taking and storing processes according to the received tray information to be accessed. The automatic material cabinet for the electronic device material trays solves the problem of automatic taking and placing of the material trays, replaces manual material taking and material storing of a warehouse, improves the management efficiency to a certain extent, and does not complete automation.

The interior of an electronic device tray automation cabinet is generally composed of a shelf and a mechanical storage device. A shelf is arranged in the cabinet and used for storing the material tray, and the material tray is directly transversely placed on a storage position of the shelf. In order to save space, the distance between the upper storage position and the lower storage position of the goods shelf is usually smaller, and meanwhile, the storage positions have a certain depth, so that a plurality of trays can be placed in one storage position. The cabinet is internally provided with a channel of a mechanical access device, the mechanical access device has the capability of moving up and down and back and forth in the channel, and can move to the position of a designated storage position of a goods shelf to take and place the material tray.

The existing storage mode of the electronic device stock disc has the following problems:

1. a plurality of trays are arranged side by side on one storage position, and when the electronic device trays are arranged outside the storage position, the mechanical access device cannot directly take and put the trays positioned on the inner side. In order to take out the innermost electronic device trays, the mechanical access device needs to lift and take out the outer trays together, the innermost trays are taken out and put into the discharge position, the inner trays are put back into the original storage position together, then the outer trays are put deep by performing a motion again, the outer trays are emptied, and then new trays can be stored. Therefore, the material taking process is complex in action, the moving distance of the mechanical access device is long, and the material taking and placing efficiency is low.

2. Because the depth of the storage position is deeper, the upper space and the lower space are smaller, and the hand claw for taking and placing needs to extend into the storage position to take materials, the hand claw also needs to be of a flat structure. When deviation occurs in the walking position of the mechanical access device, the situation that the paw stamps the tray in the storage position is easy to cause.

3. When taking the charging tray, the clamping jaw of the mechanical access device can not fix the charging tray, but only hold the charging tray. In order to prevent the tray from falling, the mechanical access device cannot move rapidly, so that the material taking efficiency is affected. And when the material tray is placed on the storage position for a long time, deformation easily occurs, and interference and clamping easily occur with a goods shelf structure after the material tray is deformed, so that the taking and placing failure is caused.

There is therefore a need for improvements in existing electronic component inventory storage devices and approaches.

In the grabbing process, when the claw body 2321 at the tail end of the rotating arm 2322 rotates to the position above the electronic device tray, the lifting cylinder 2324 controls the rotating arm 2322 and the claw body to descend to the electronic device tray.

In other embodiments, the lifting cylinder may be disposed at the end of the rotating arm 2322, and then the claw body is directly disposed on the lifting cylinder, so that the lifting cylinder only drives the claw body to lift, and does not need to drive the rotating arm and the rotation driving mechanism to lift together. In other embodiments, a lift motor or other lift drive mechanism may be used in place of the lift cylinder.

As shown in fig. 9, the electronic device tray is in a circular disc shape, and includes two opposite panels 41, a clamping slot 43 between the two panels 41 is used for winding the electronic device, and a central hole is provided in the middle of the panels 41 to fixedly connect the two panels. In the above embodiment, the claw body 2321 of the tray claw 232 may be an insertion type claw body, where the claw body 2321 includes a plurality of claw pieces capable of gathering and spreading toward the center, and the claw body 2321 is inserted into the center hole 42 and spreads outward to clamp the tray. In other embodiments, the gripper body of the tray gripper may also be a suction-type gripper body, or a gripper body similar to the gripper mechanism 2311 described above. In this embodiment, the claw body 2321 of the tray claw 232 is an insertion-type claw body, so that the volume of the claw body can be reduced, and the stability of the tray clamping can be improved.

As shown in fig. 4 and 5, in some embodiments, the upper surface of the tray is provided with more than two storage slots along the depth direction; the tray gripper 231 pulls the distance corresponding to the tray according to the position of the target storage slot corresponding to the electronic device tray to be taken out on the tray, so that the target storage slot is placed outside the storage position. That is, the tray gripper 231 does not pull the entire tray out of the storage place every time, for example, when the electronic component trays in the outermost storage slot of the tray are to be fetched and placed, the tray gripper only needs to pull the tray out of the storage slot of the outermost storage slot beyond the shelf.

Finally, it should be noted that, although the foregoing embodiments have been described in the text and the accompanying drawings of the present application, the scope of the patent protection of the present application is not limited thereby. All technical schemes generated by replacing or modifying equivalent structures or equivalent flows based on the essential idea of the application and by utilizing the contents recorded in the text and the drawings of the application, and the technical schemes of the embodiments are directly or indirectly implemented in other related technical fields, and the like, are included in the patent protection scope of the application.
