Description

Technical Field

[0001] The present invention relates to the technical field of magnetic tile processing, and in particular to an automatic feeding device for magnetic tile grinding processing and a use method thereof. Background Art

[0002] A magnetic tile is a permanent magnet designed in a tile (arc) shape. It is a core magnetic component in modern high-efficiency motors and generators. Its unique arc-shaped structure allows it to fit tightly against the cylindrical surface of a motor's rotor or stator, generating a stable, uniform, and strong magnetic field in the air gap. The core value of the magnetic tile lies in its ability to provide a long-lasting magnetic field without the need for external power, significantly improving the motor's efficiency, power density, and reliability while simplifying its structure. It is widely used in a variety of applications, from permanent magnet DC motors in automotive window motors, power tools, and household appliances (such as vacuum cleaners and fans) to permanent magnet synchronous motors in industrial drives, new energy vehicle drives, and air conditioning compressors. Depending on performance requirements and cost considerations, magnetic tiles can be made of different materials. Common materials include economical and durable ferrite, high-performance but more expensive neodymium iron boron (sintered or bonded), and high-temperature-resistant samarium cobalt. Key performance indicators include magnetic strength (remanence), resistance to demagnetization (coercivity), and maximum operating temperature.

[0003] Some defective products often appear during the processing of magnetic tiles. In order to avoid ineffective processing of magnetic tiles, they need to be inspected during the loading process to identify defective products. Most existing inspection methods require stopping or slowing down the machine to sort out defective products after inspection, resulting in the accumulation of magnetic tiles at the inspection station, friction and collision with each other, and dust attached to the good magnetic tile mountain, which may lead to a decrease in the yield of later processing.

10. The method for using the automatic feeding device for magnetic tile grinding according to any one of claims 1 to 9, characterized in that: include: S1, the magnetic tile is placed in the storage box (102), and then the magnetic tile at the bottom is pushed outward in sequence by the control of the electric telescopic rod (103), so that the magnetic tile falls into the storage slot (105), and the magnetic tile is turned over by the electric turntable (104), and the two sides of the magnetic tile are inspected by the upper and lower first detection cameras (107) and the second detection camera (108); S2, the fan (208a) extracts gas from the outer box (207a), and the extracted gas is transported to the gas collecting cylinder (208d) through the second connecting pipe (208b) for storage, so that a high-pressure environment is formed in the gas collecting cylinder (208d), and at the same time, debris generated by the discarded magnetic tiles in the filter (207b) is adsorbed on the filter (207b); S3. When unqualified magnetic tiles are detected, the information is transmitted to the external computer, and the computer sends a command to the solenoid valve (306b), which opens it so that the high-pressure gas below the partition (306a) rushes upward, squeezing the second piston plate, causing the sleeve rod (306c) to move upward, and the sleeve rod (306c) is driven to rotate through the cooperation of the slide groove (306d) and the clamping rod (306e), so that the vertical rod (205) rotates a certain angle, driving the material distribution plate (204) to rotate to one side, so that the second unloading chute (202) is closed and the third unloading chute (203) is opened; S4.
