Description

Technical Field

[0001] This utility model relates to the field of magnetic tile production, and in particular to a magnetic tile grinding device. Background Technology

[0002] Magnet tiles are permanent magnet materials with magnetic properties. They are an important type of magnetic component and are now widely used in various electronic devices, mechanical transmission systems, medical devices, the automotive industry, and other fields.

[0003] During the production of magnetic tiles, the surface usually needs to be polished to improve the overall quality of the tiles and ensure the reliability and stability of the products. Existing polishing devices, such as the grinding equipment and method for magnetic tile production disclosed in Chinese Patent CN117718852A, include a processing table, with sliding frames fixed on both the front and back sides of the center of the processing table. A polishing cam is rotatably installed between the lower outer walls of the two sliding frames. The device also includes a positioning mechanism. The positioning mechanism includes a through-groove frame, a slide rod, a screw rod, a U-shaped slide plate, two telescopic plates, and two L-shaped plates. The through-groove frame is fixed to the top of the processing table, and the slide rod is fixed to the top front of the through-groove frame.

[0004] However, in practical applications, the aforementioned magnetic tile grinding devices still have the following drawbacks:

[0005] Firstly, it lacks a screening function and can only perform batch uniform polishing, resulting in high energy consumption;

[0006] Secondly, the lack of a drying function necessitates an additional drying process for the magnetic tiles, which severely restricts the production efficiency of the magnetic tiles.

[0130] Working principle and usage:

[0131] Step 1, Pre-setting:

[0132] Press the start switch to perform a no-load test.

[0133] Adjust the grinding wheel 407, polishing wheel 414, and arc-shaped limit block according to the size of the magnetic tile, i.e., replace them with different models (size, curvature, etc.) to fit the magnetic tile. By pressing the adjustment switch one, the PLC controller outputs a signal to the screw jack 301, and the moving end of the screw jack 301 moves in an orderly manner, thereby controlling the position of the arc-shaped limit block.

[0134] By pressing the adjustment switch 2, the PLC controller outputs a signal to the screw jack 2 405, and the moving end of the screw jack 2 405 moves in an orderly manner, thereby controlling the position of the grinding wheel 407.

[0135] By pressing the adjustment switch three, the PLC controller outputs a signal to the screw jack three 412, and the moving end of the screw jack three 412 moves in an orderly manner, thereby controlling the position of the grinding wheel 414.

[0136] The second step is polishing:

[0137] Place the magnetic tile to be processed into the vibratory feeder 201; press the grinding switch, and the PLC controller outputs a signal to the vibratory feeder 201 and the conveyor belt 202.

[0138] The vibratory feeder 201 and conveyor belt 202 are started, transmitting the magnetic tiles to the area below the distance sensor module 1; the distance sensor module 1 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the push rod motor 203, push rod motor 204, electromagnet 1, and electric lifting device 303.

[0139] Push rod motor 204 drives the electromagnet to move downwards, grasping the magnetic tile, and under the action of push rod motor 203, moves it onto the detection tray 304. Electric lifting device 303, after a delay, drives the detection tray 304 upwards.

[0140] The distance sensor module 2 at the preset position outputs a signal to the PLC controller, which in turn outputs a signal to the push rod motor 203, push rod motor 204, and electromagnet 1. The push rod motors 203, 204, and electromagnet 1 work together to transfer the magnetic tile to conveyor belt 408 (i.e., a standard-compliant magnetic tile).

[0141] When the distance sensor module 2 below the preset position outputs a signal to the PLC controller, the PLC controller outputs a signal to the lead screw stepper motor 305, the push rod motor 306, the stepper motor 307, and the electromagnet 2 (i.e., the magnetic tile that needs to be polished).

[0142] The push rod motor 306 drives the stepper motor 307 to move downwards, the stepper motor 307 drives the "T" shaped mounting rod to rotate, the electromagnet 2 is activated, and the magnetic tile is grasped and transferred to the conveyor belt 401 under the action of the lead screw stepper motor 305.

[0143] The distance sensor module outputs a signal to the PLC controller, and the PLC controller outputs a signal to the conveyor belt 2 (401), the push rod motor 4 (403), and the servo motor 1 (406).

[0144] Conveyor belt 2 401 starts, servo motor 1 406 starts, grinding wheel 407 starts working, and then push rod motor 403 drives stop lever 1 404 to move to the left in an orderly manner.

[0145] After being polished, the magnetic tile enters the connecting ramp 402; then, it reaches the area below the distance sensor module 4. The distance sensor module 4 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the lead screw stepper motor 410, the electric telescopic rod 411, and the electromagnet 3.

[0146] The electric telescopic pole 2 (411) and the electromagnet 3 start to grab the magnetic tile. The lead screw stepper motor 2 (410) then transfers the magnetic tile to the conveyor belt 3 (408) after a delay.

[0147] The PLC controller outputs signals to conveyor belt 3 (408) and servo motor 2 (413). Conveyor belt 3 (408) starts, and servo motor 2 (413) drives the grinding wheel 414 to rotate, grinding the magnetic tiles. The ground magnetic tiles then enter the mesh conveyor belt 501.

[0148] The third step is drying:

[0149] The PLC controller outputs a delayed signal to the mesh conveyor belt 501, heating wire 502, and circulating fan; the mesh conveyor belt 501, heating wire 502, and circulating fan start to dry the magnetic tiles.

[0150] Step 4, repeat:

[0151] During the grinding process, when the grinding wheel 407 and the polishing wheel 414 are started, the supply pump and solenoid valve are activated, and the high-pressure nozzle cools down the grinding wheel 407 and the polishing wheel 414.

[0152] The ground mixture enters sedimentation tank 602, and then circulates through a filter membrane into storage tank 601. During this process, a magnetic rod recovers magnetic materials from the mixture.

[0153] Example 2, based on Example 1, adds an electric lifting device 2 between the vibratory feeder 201 and the base 101.
