Example

[0024] See also Figures 1-4The present invention provides the following technical solutions: a material classification management rack based on RFID, comprising a material classification rack 1, with a reader / writer 3 on one side of the material classification rack 1, the reader / writer 3 being used to identify material information with RFID tags, thereby realizing automatic reading and recording of the material information. A post-classification window 4 is provided on the back of the reader / writer 3 and located on the back side of each compartment. The post-classification window 4 is provided on the back side of each compartment of the material classification rack 1, and is used to display or confirm the status of the classified materials, so as to facilitate inspection by operators. A three-axis mobile module 5 is provided at the rear of the material classification rack 1, a support seat 16 is provided at the terminal end of the three-axis mobile module 5, a material classification and transfer mechanism 12 is provided at the free end of the support seat 16, the material classification and transfer mechanism 12 having two relatively movable clamping claws 11 at one end away from the support seat 16, the two clamping claws 11 clamping the goods in the material classification rack 1, the material classification and transfer mechanism 12 including a drive motor 15 installed on the outer wall of the support seat 16, and an L-shaped anti-shake support plate 17 on both sides of the outer wall of the clamping cylinder 13 behind the clamping claw 11. The three-axis moving module 5 can realize the precise movement of the material classification and moving mechanism 12 in three-dimensional space, thereby improving the efficiency and accuracy of material classification.

[0025] In this embodiment, the output shaft of the drive motor 15 is connected to a turntable 14, which is fixedly connected to one end of the clamping cylinder 13. The clamping claw 11 is connected to the clamping cylinder 13, and two L-shaped anti-shake support plates 17 are positioned opposite each other. The clamping claw 11 is used to grasp and release materials. The clamping cylinder 13 provides power. The turntable 14 and the drive motor 15 work together to enable the clamping claw 11 to rotate within a certain angle range to accommodate materials of different shapes and sizes.

[0026] In this embodiment, multiple air cushion springs 23 are symmetrically mounted on the inner wall of each L-shaped anti-shake support plate 17. Each air cushion spring 23's end, facing away from the L-shaped anti-shake support plate 17, elastically abuts against the outer wall of the clamping cylinder 13. The L-shaped anti-shake support plates 17 and air cushion springs 23 work together to reduce vibration during the movement of the material sorting and moving mechanism 12, protecting the materials from damage while ensuring accurate movement.

[0027] In this embodiment, the three-axis moving module 5 includes two symmetrically arranged Z-axis guide rails 8, a Y-axis guide rail 6 longitudinally slidably connected between the two Z-axis guide rails 8, and an X-axis hydraulic telescopic column 10 slidably connected to the Y-axis guide rail 6. A support base 9 is welded to the bottom end of each Z-axis guide rail 8.

[0028] In this embodiment, the surface of the Y-axis guide rail member 6 is slidably connected to the Y-axis slider member 7 , and the tail end of the X-axis hydraulic telescopic column 10 is fixedly installed on the outer wall of the Y-axis slider member 7 .

[0029] In this embodiment, the telescopic free end of the X-axis hydraulic telescopic column 10 is fixedly connected to the tail end of the support seat 16 .

[0030] In this embodiment: the top surfaces of the support seat 16 and the Y-axis slider 7 are both welded with fixed blocks 18, and the outer wall of the fixed block 18 of the support seat 16 is welded with a telescopic positioning rod 19, and the free end of the telescopic positioning rod 19 extends through and extends to the outside of the fixed block 18 of the Y-axis slider 7.

[0031] In this embodiment: the telescopic positioning rod 19 is located on the outer side of the fixed block 18 of the Y-axis slider 7 and is sleeved with an extrusion spring 20 , and the end of the telescopic positioning rod 19 away from the fixed block 18 is connected to the limit plate 21 through a locking bolt 22 .

[0032] In this embodiment, a power distribution control cabinet 2 is mounted on the outer wall of a material sorting rack 1. A reader / writer 3 is mounted on the surface of the power distribution control cabinet 2, which also features a display screen and buttons. The power distribution control cabinet 2 houses a programmable logic controller (PLC) for controlling the on / off functions of various electrical components. All electrical components described herein are electrically connected to an external main controller and 220V mains power. The main controller can be a conventional, known device such as a computer.

[0033] The working principle and usage process of this utility model are as follows: When using this RFID-based material classification and management rack, the power distribution control cabinet 2 is first turned on to power the entire system and ensure that all electrical components are in normal working order. The operator places materials with RFID tags in designated locations on the material classification rack 1. The reader / writer 3 reads the RFID tag information on the materials and transmits the information to the programmable logic controller (PLC) in the power distribution control cabinet 2. Based on this information, the PLC determines the material's category and specific storage location, and plans the movement path of the material classification and movement mechanism 12.

[0034] Following the instructions from the PLC, the three-axis movement module 5 begins operation. The X-axis hydraulic telescopic column 10 first moves the material sorting and moving mechanism 12 to the designated X-axis position. Then, through the coordination of the Y-axis guide 6 and the Y-axis slider 7, the material sorting and moving mechanism 12 is moved to the target Y-axis position. Finally, the Z-axis guide 8 adjusts the Z-axis height to ensure that the clamping claw 11 can accurately reach the target material. The clamping claw 11 opens under the action of the clamping cylinder 13 and closes after approaching the target material, completing the material grabbing. During this process, the L-shaped anti-shake support plate 17 and the air buffer spring 23 work together to reduce vibration during the movement of the clamping claw 11, ensuring the safety of the material.

[0035] The material sorting and transfer mechanism 12 moves the materials from their current location to the corresponding position in the sorting window 4, following a path pre-set by the PLC. Upon reaching the target location, the gripping claws 11 release, placing the materials in the designated position. If necessary, the turntable 14 and drive motor 15 coordinate to adjust the angle of the materials to ensure proper placement.

[0036] After the materials are placed, the system reads the material information again through reader / writer 3 to confirm whether the materials have been placed correctly. If the materials are placed correctly, the system displays a success message on the display screen of distribution control cabinet 2. If there is an error, the system issues an alarm and prompts the operator to intervene manually. The system saves the relevant information of this operation in the database for subsequent query and management.

[0037] After completing one classification operation, the material classification and movement mechanism 12 returns to the initial position and prepares for the next operation.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
