Description

Technical Field

[0001] This utility model relates to a surface treatment device, and more particularly to a magnet surface treatment device. Background Technology

[0002] Magnets are objects that can generate magnetic fields and attract magnetic materials such as iron, nickel, and cobalt. Magnet manufacturing mainly involves the following steps: smelting → powder preparation → pressing → sintering → surface finishing → electroplating → magnetization. The sintering process is generally carried out in a sintering furnace. Through sintering, the density and magnetic properties of the material are improved, thus enhancing the quality of the magnet.

[0003] After the magnet is sintered, its surface needs to undergo processes such as polishing, alkaline washing, acid washing, and electroplating. Burrs and oxide layers on the magnet surface can affect its performance, so the end faces of the magnet need to be polished. Existing polishing machines usually polish one end of the magnet, then remove the magnet to polish the other end, which is inefficient. Utility Model Content

[0006] In the aforementioned magnet surface treatment equipment, the upper end of the machine body is provided with a fan-shaped opening corresponding to the material inlet and outlet areas, and vertically arranged baffles are provided on both sides of the fan-shaped opening.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0014] Example. A magnet surface treatment apparatus, configured as follows: Figure 1-2 As shown, the device includes a body 1, a rotating shaft 2 in the middle of the body 1, an mounting cylinder 3 on the rotating shaft 2, and evenly distributed clamping grooves 4 on the mounting cylinder 3. Inside the body 1, there are a feeding / discharging area 5, an upper end face grinding area 6, an upper end face cleaning area 7, a lower end face grinding area 8, and a lower end face cleaning area 9 arranged sequentially in the direction of rotation of the rotating shaft 2. The upper end face grinding area 6 has multiple sets of upper electric grinding machines 10 on the upper side of the mounting cylinder 3, corresponding to the positions of the clamping grooves 4. The lower end face grinding area 8 has a lower end face grinding machine 11 on the lower side of the mounting cylinder 3. The upper end face cleaning area 7 and the lower end face cleaning area 9 are equipped with cleaning brushes 12 for cleaning the end face of the magnets.

[0015] The upper end of the machine body 1 is provided with a fan-shaped opening 13 corresponding to the material inlet and outlet area 5, and vertically arranged baffles 14 are provided on both sides of the fan-shaped opening 13.

[0016] The clamping groove 4 is provided with multiple sets of clamping blocks 15 with protruding structures.

[0017] The placement tray 6 has a limiting block 14 on its lower side that corresponds to the limiting groove 13, and a mating block 15 on both sides of the placement tray 6, with a mating groove 16 in the mating block 15.

[0018] The lower side of the feed and discharge area (5) is provided with a collection hopper 16 for collecting the finished products after processing. The collection hopper 16 is provided with a guide plate 17 corresponding to the clamping groove 4 in the mounting cylinder 3.

[0019] The principle of this utility model: This application mainly addresses the problem of low processing efficiency in existing grinding machines, which require processing one end before processing the other. This application divides the internal space of the machine into five parts: a feeding / discharging area, an upper surface grinding area, an upper surface cleaning area, a lower surface grinding area, and a lower surface cleaning area. This application uses a limit switch to detect the movement position, thereby controlling the rotation angle of the mounting cylinder 3. During the movement of the mounting cylinder driven by the rotating shaft 2, magnets can be manually added and removed in the feeding / discharging area, improving processing efficiency. The magnets are placed from the feeding / discharging area into the clamping groove 4 of the mounting cylinder 3. The clamping groove 4 has a raised clamping block 15 made of flexible or magnetic material to fix the magnets. Then, the rotating shaft 2 is driven by a motor, and the magnets enter the next stage, namely the upper surface grinding area 6, while the previously placed magnets also enter... Moving to the next stage, the magnet undergoes grinding and cleaning of the lower end face in sequence to complete the cycle. At this point, the worker removes the magnet that has just been cleaned in the lower end face cleaning area 9, puts in a new magnet, and completes the processing. The baffle 14 can reduce the harm to workers caused by flying impurities and debris, ensuring good safety. Since the exposed part of the magnet relative to the clamping groove 4 is relatively small during processing, it is difficult for workers to remove it directly. Therefore, this application can press the magnet to make it fall. In order to avoid serious impact during the fall, this application further sets a guide plate 17 to guide the magnet. In order to reduce the impact of impurities and debris on the finished product, a baffle can also be set on the lower side of the mounting cylinder 3 in the inlet and outlet area to block impurities.
