[0002] Magnets are widely used basic electronic and electrical components, primarily found in computers, mobile phones, televisions, communications, toys, audio equipment, automation equipment, and MRI. Currently, neodymium iron boron magnets are widely used as high-performance permanent magnets. In the production and processing of electronic products, diaphragms (microphone, earphone, speaker, etc.), and electroacoustic equipment, some equipment requires magnets that are not conventionally rectangular or circular. Depending on the product processing requirements, magnets need to be assembled into a shape and size suitable for the equipment. Existing magnet assembly press-fitting fixtures suffer from poor positioning accuracy and low press-fitting efficiency, failing to meet the demands of mass production. Utility Model Content

[0010] Furthermore, the guide plate is provided with more than five magnet grooves.

[0011] Furthermore, the lever is rectangular, and the height of the lever is less than the thickness of the guide plate, but greater than two-thirds of the thickness of the guide plate.

[0012] This utility model has the following beneficial effects: by setting the magnet slide groove on the guide plate as an upper slide groove and a lower slide groove, setting the first magnet positioning block on the base, and setting the positioning slot at the connection of the upper slide groove and the lower slide groove, the magnet blocks can be conveniently positioned. By moving the guide plate and the cover plate, the push-fitting operation can be completed quickly. The positioning is accurate, the push-fitting is convenient, and the operation is simple during the push-fitting of the magnet blocks. Attached Figure Description

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0020] like Figures 1 to 6In the embodiment of the magnet pushing and arranging fixture of this utility model shown, the magnet pushing and arranging fixture includes a base 10, a guide plate 20, and a cover plate 30; the guide plate 20 is slidably mounted on the base 10, and the cover plate 30 is slidably mounted on the guide plate 20; the guide plate 20 is provided with a plurality of parallel magnet sliding grooves 21, each magnet sliding groove 21 including an upper sliding groove 211 and a lower sliding groove 212; the base 10 is provided with a first magnet positioning block 11 corresponding to the upper end of the upper sliding groove 211, the first magnet positioning block 11 can be positioned in the upper sliding groove The lower end of the first magnet positioning block 11 is adapted to the shape of the first magnet 41. The connection between the upper sliding groove 211 and the lower sliding groove 212 is provided with a positioning slot 213 adapted to the shape of the second magnet 42. The second magnet 42 is placed in the positioning slot 213 and slides on the base 10 with the guide plate 20. The cover plate 30 is provided with a lever 31 that is inserted into the lower sliding groove 212. The lever 31 is used to drive the third magnet 43 in the lower sliding groove 212 to move upward along the lower sliding groove 212.

[0021] When using the above-mentioned magnet pushing and arranging fixture, such as Figure 2 The first magnetic block 41, the second magnetic block 42, and the third magnetic block 43 are placed in the second magnetic groove 21 from right to left. Magnetic blocks to be pushed together are placed sequentially in each magnetic groove 21. After applying adhesive to the bonding surfaces of each magnetic block, the cover plate 30 is fastened onto the guide plate 20, ensuring that the pusher block 31 is inserted into the lower end of the lower groove 212 (the end furthest from the upper groove). After the cover plate is fastened, the cover plate and guide plate are moved together towards the upper edge of the base (the side with the first magnetic positioning block 11). At this time, the second magnetic block 42 and the third magnetic block 43 move upwards on the base along with the guide plate 20. The first magnetic block 41 is in the first magnetic groove 21. Under the blocking action of the positioning block 11, the second magnetic block 42 moves with the guide plate 20 and abuts against the first magnetic block 41. The guide plate and cover plate stop moving, so that the first magnetic block 41 and the second magnetic block 42 are bonded. Keeping the base and guide plate still, the cover plate 30 is moved again. The push block 31 drives the third magnetic block 43 to move upward in the sliding groove 212 and abut against the second magnetic block 42, so that the third magnetic block 43 and the second magnetic block 42 are bonded. Thus, the push-fit bonding of the three magnetic blocks is completed. The magnetic block push-fit bonding process is accurate in positioning, convenient in pushing and fitting, and simple in operation, and can quickly complete the push-fit bonding operation.

[0022] In one embodiment of this application, preferably, the base 10 is provided with baffles 12 on both sides, and the guide plate 20 is installed between the two baffles 12 and slides relative to the base 10 along the baffles 12, so that the guide plate 20 is easy to install on the base and slides reliably.

[0023] In one embodiment of this application, preferably, the guide plate 20 is provided with guide grooves 22 on both sides, and the magnet slide groove 21 is located between the two guide grooves 22; the base 10 is provided with guide posts 13 that are inserted into the guide grooves 22; preferably, the guide posts are cylinders, so that the guide plate can reliably slide up and down on the base.

[0024] In one embodiment of this application, preferably, the length of the guide groove 22 is greater than the length of the magnet slide groove 21, such as... Figure 2 As shown, when the guide plate 20 is aligned with the base 10, the guide post 13 is located in the middle of the guide groove 22.

[0025] In one embodiment of this application, preferably, the guide plate 20 is provided with five or more magnet grooves 21, which can complete the pushing and bonding of multiple sets of magnets at one time.

[0026] In one embodiment of this application, preferably, the toggle block 31 is rectangular, and the height of the toggle block 31 is less than the thickness of the guide plate 20 and greater than two-thirds of the thickness of the guide plate 20; so that the toggle block 31 does not contact the base and can reliably move the third magnetic block.
