The specific structure of the support assembly 5 is assembled from two long support profiles 52 and two short support profiles 52 to form a rectangular frame. After assembly, the two long support profiles 52 are parallel, and the two short support profiles 52 are parallel. The connection between them is fixed by bolts or welding. The mounting profile 51 is installed in the middle of the frame structure. The mounting profile 51 is parallel to the short support profile 52.

The specific structure of the read-write head component 54 is a cylinder 14, which is fixed on the bracket. The read-write head mounting plate 16 is fixed on the output end of the cylinder 14. The output end of the cylinder 14 drives the read-write head mounting plate 16 to move, and the read-write head 13 is fixed on the read-write head mounting plate 16. This read-write head 13 is used to read the RFID chip on the tray 35 to determine whether it is a sub-board tooling material or a tool material.

[0038] The servo module 11 is bolted on the slide mounting assembly 4, and its movement direction is from one opening to another, that is, it moves along the length of the carrier plate 41. Its structure and principle are conventional means and will not be described in detail here.

[0039] The information reading component 12 is mounted on the servo module 11 and is driven to move by the servo module 11. The specific structure is that the slider connecting plate 121 is connected to the servo module 11, and is configured so that the slider in the servo module 11 drives the slider connecting plate 121 to move back and forth.

[0042] During the use of the AGV material handling information reading device, the AGV trolley 31 drives the tray 35 to move to the bottom of the slide mounting assembly 4 in a lifted state, and then lowers the tray 35 so that the groove on the tray 35 is aligned with the protrusion of the positioning pin fixed end 8 to form a limit. At this time, the fixed read-write head 13 located at the bottom is used to read the RFID chip on the tray 35 to determine whether it is a sub-board tooling material or a tool material, and then start the servo module 11 to drive the information reading assembly 12 to move. At this time, the read-write head 13 on the information reading assembly 12 reads the RFID chip information of each workstation tooling on the tray 35 to obtain the quantity of materials on the tray 35 and the detailed information of the materials at each workstation. After the information is obtained, the AGV trolley 31 lifts the tray 35 to separate it from the protrusion of the positioning pin fixed end 8 and transport it to the loading end of the production line. The robot can directly grab the material, saving a lot of time.
