TECHNICAL FIELD

[0001] The application relates to the field of neodymium-iron-boron magnet spraying, in particular to a surface spraying device for neodymium-iron-boron magnet production. BACKGROUND

[0002] Neodymium-iron-boron magnet, also known as neodymium-iron-boron magnet, is an intermetallic compound formed by rare earth element neodymium (Nd) and iron (Fe) and boron (B), and its chemical formula is Nd2Fe14B. Neodymium-iron-boron magnet spraying is a surface treatment technology aimed at improving the corrosion resistance, oxidation resistance and service life of neodymium-iron-boron magnet. Commonly used spraying materials include epoxy resin, polyester resin, acrylate, etc. These materials can form chemical bonding with the surface of neodymium-iron-boron magnet, improve the adhesion of the coating, and at the same time have good corrosion resistance and oxidation resistance.

[0003] At present, when spraying epoxy resin on the surface of neodymium-iron-boron magnet, the neodymium-iron-boron magnet is placed on the clamping assembly for fixation (the surface spraying device for neodymium-iron-boron magnet production is disclosed in CN210628085U), only the clamping assembly is used to fix the neodymium-iron-boron magnet, and then the surface of the magnet is sprayed by the spraying equipment. The clamping assembly does not have a turnover mechanism, and after the surface of the magnet is sprayed, the magnet needs to be turned over one by one to spray the other side, so it still needs to be improved. CONTENT OF THE UTILITY MODEL

[0004] By installing a turnover mechanism on the placing assembly of the neodymium-iron-boron magnet, the magnet can be turned over during clamping. After the surface of the neodymium-iron-boron magnet is sprayed, all the magnets can be quickly sprayed, which is convenient and fast to operate. The application provides a surface spraying device for neodymium-iron-boron magnet production.

[0005] The application provides a surface spraying device for neodymium-iron-boron magnet production, which adopts the following technical scheme:

[0006] A surface coating device for producing neodymium iron boron magnets includes a base frame and a drive mechanism mounted on the base frame. A coating mechanism is mounted on the drive mechanism. The drive mechanism includes a fixed frame, which is fixedly connected to the base frame. A flipping mechanism is mounted on the fixed frame, which includes a third motor. The third motor is mounted on the side of the fixed frame, and its output end passes through the fixed frame. A fixed frame is fixedly connected to the output end of the third motor. The inner wall of the fixed frame has a convex cross-section. A cover plate is fastened to the top and bottom of the fixed frame. Placement plates that fit against the inner wall of the fixed frame are adhered to the opposite surfaces of the two cover plates. The inner wall of the fixed frame has symmetrically formed movable grooves about the center of the two placement plates. Four rotating shafts extending into the movable grooves are rotatably connected to the four corners of the top and bottom of the fixed frame. Each of the eight rotating shafts has a pulley fixedly mounted on it. A belt is installed between the four pulleys inside the two movable grooves. Limiting plates that abut against the two cover plates are fixedly connected to the side walls of the eight rotating shafts.

[0007] By adopting the above technical solution, only one placement plate needs to be installed when spraying one side of the magnet. During installation, the cover plate is fastened to the fixed frame, and the rotating shaft on the fixed frame is rotated to make the pulley rotate and the limiting plate rotate out of the movable groove. The cover plate is then fixed, thus providing a placement platform for the magnet. The magnet is placed on the surface of the placement plate and sprayed by the spraying component. When spraying the other side, another cover plate is fastened to the fixed frame and fixed by the limiting plate. At this time, the magnet is clamped. The fixed frame is rotated 180 degrees by the third motor to realize the position swap of the two cover plates. Then the unsprayed magnet is facing the spraying component, and the top cover plate is removed to expose the magnet to complete the spraying. There is no need to flip the magnets one by one.

[0008] Optionally, the flipping mechanism further includes a steering wheel, with two of the rotating shafts at the top and bottom of the fixed frame protruding, and the ends of the two protruding rotating shafts are fixedly connected to the steering wheel.

[0009] By adopting the above technical solution, it is easy to rotate the rudder to drive the four pulleys simultaneously, thereby controlling the four limit plates to clamp and limit the cover plate at one time.

[0010] Optionally, the surfaces of the placement plate and the cover plate are provided with holes at equal intervals, and the cross-sections of the cover plate and the placement plate are convex.

[0011] By adopting the above technical solution, it is easier for the paint to be exposed through the holes during spraying.

[0012] Optionally, both cover plates are threaded with handles that are rotatably connected to the placement plate. The handles have an I-shaped cross-section and are located at the center of the cover plate.

[0013] By adopting the above technical scheme, the cover plate and the placing plate are convenient to take, and the placing plate slides on the inner wall of the fixed frame by rotating the handle, which is beneficial to clamping the magnets with different thicknesses.

[0014] Optionally, the fixed frame has a rectangular structure in cross section, and the area of the fixed frame is smaller than the opening area of the fixed frame.

[0015] By adopting the above technical scheme, the fixed frame rotates at the internal opening of the fixed frame, and the rotation of the fixed frame is not blocked.

[0016] Optionally, the driving mechanism further comprises a first motor, the fixed frame is provided with the first motor on both sides, the output ends of the two first motors are fixedly connected with lead screws through couplings, the lead screws are rotatably connected with the fixed frame, the fixed frame is fixedly connected with two groups of guide rods parallel to the lead screws, the guide rods are slidably connected with sliding seats, the sliding seats are threadedly connected with the lead screws, and the top portions of the sliding seats are fixedly connected with support frames.

[0017] By adopting the above technical scheme, the sliding seat is moved on the lead screw by the rotation of the first motor after the magnet is placed, and the movement of the spraying mechanism is completed, so that the magnet is conveniently sprayed in all directions.

[0018] Optionally, the spraying mechanism comprises a screw rod and a slide rod, the screw rod is rotatably connected between the support frames, the slide rod is fixedly connected between the support frames, a spraying assembly is slidably connected with the slide rod and threadedly connected with the screw rod, a nozzle is mounted at the bottom of the spraying assembly, and a second motor is fixedly connected with the screw rod and mounted on the side wall of one of the support frames.

[0019] By adopting the above technical scheme, the second motor is started to realize the movement of the spraying assembly transversely to the nozzle during spraying.

[0020] Optionally, the limiting plates have a cuboid structure, and the four limiting plates at the top of the cover plate are diagonally distributed.

[0021] By adopting the above technical scheme, the cover plate is stably limited at multiple points.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. When spraying one side of the magnet, only one placement plate needs to be installed. During installation, the cover plate is fastened to the fixed frame. Further rotation of the rotating shaft on the fixed frame enables the four pulleys to rotate in conjunction with the belt, rotating the four limiting plates out of the movable groove, thereby fixing the cover plate. This provides a placement platform for the magnet.

[0024] 2. During spraying, place the magnet on the prepared placement plate and spray it through the spraying assembly. When spraying the other side of the magnet, fasten another cover plate on the fixed frame and fix it with the limiting plate. At this time, the magnet is clamped. The third motor drives the fixed frame to rotate 180 degrees, so that the positions of the two cover plates are swapped. Then the unsprayed magnet is opposite the spraying mechanism. Remove the top cover plate to expose the magnet and complete the spraying. There is no need to flip the magnet over one by one. Attached Figure Description
