Description

A drawer-type intelligent material tower storage Technical Field

[0001] This invention relates to the field of material storage tower technology, and in particular to a drawer-type intelligent material tower storage system. Background Technology

[0002] Currently, intelligent material storage towers in warehouses are usually arranged side by side. This means that it takes time for robotic arms to move to the corresponding storage unit, resulting in slow efficiency. Drawers are pulled out from the front of the tower, requiring significant space between rows, leading to low space utilization. For storing different goods, previously each product type used a separate drawer, with a near one-to-one correspondence between drawers and products. Therefore, storing different products usually required replacing the entire drawer, wasting costs and time. Traditionally, clamping was used for material handling, which can damage products. While some structures use suction cups, suction cups suffer from inaccurate positioning. Summary of the Invention

Both the left and right sides have magnetic suction components 3342-3. The storage drawer 22 has positioning holes 2201 that mate with positioning rods 3342-35. Positioning is achieved by inserting the positioning rods 3342-35 of the magnetic suction components 3342-3 into the positioning holes 2201 of the storage drawer 22, and by using electromagnets 3342-34 to magnetically attract the storage drawer 22. Combined with the X-axis drive device 3341 controlling the left and right movement of the sliding frame 3342-1, the storage drawer can be moved... When drawer 22 is pulled out from frame 21, the push rod 3342-32 contacts the storage drawer 22, and the third spring 3342-33 is compressed. When the storage drawer 22 retracts, the electromagnet 3342-34 is de-energized, and the fourth spring 3342-36 pushes the push rod 3342-32 outward, separating the storage drawer 22 from the electromagnet 3342-34. This prevents residual magnetism from attracting the storage drawer 22 and continuing to drive its movement. The third spring 3342-33 also prevents the electromagnet 3342-34 from impacting the storage drawer 22, acting as a buffer.

[0054] The carriage 31 includes a frame 311, a slide rail 312, a lower connecting seat 313, an upper connecting seat 314, and a first lead screw 315. The frame 311 is vertically fixed above the base frame 1. Two slide rails 312 are provided and installed on adjacent sides of the frame 311 respectively. The upper connecting seat 314 and the lower connecting seat 313 are respectively installed at the upper and lower ends of the frame 311 and extend forward. The upper and lower ends of the first lead screw 315 are rotatably connected to the upper connecting seat 314 and the lower connecting seat 313. The first lifting drive device 322 and the second lifting drive device 332 are respectively connected to the first lead screw 315. Both the first lifting drive device 322 and the second lifting drive device 332 use motor-driven gear sets to drive the first lead screw nut to rotate. The first lead screw nut cooperates with the first lead screw 315 to realize lifting control. In addition, the lifting control can also be realized by synchronous belt or gear rack transmission.

[0055] The above description is not intended to limit the scope of the present invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the present invention.
