Description

Technical Field

[0001] This utility model relates to magnet assembly technology, and in particular to a magnet assembly pushing mechanism. Background Technology

[0002] With the development of technology, magnetic materials have been widely used in industries such as motors, electroacoustics, automobiles, and electronics. In the production and processing of electronic products, diaphragms (microphones, headphones, speaker diaphragms, etc.), and electroacoustic equipment, some equipment requires magnets that are not conventionally rectangular or circular shapes. Magnets need to be combined into a designed shape and size according to the product's design requirements. Among these, the Halbach array is a composite magnetic structure, an approximately ideal engineering structure. Permanent magnets with different magnetization directions are arranged in a specific order, resulting in a significantly stronger magnetic field on one side and a significantly weaker magnetic field on the other. The goal is to generate the strongest magnetic field in the working area using the minimum number of magnets.

[0003] In the manufacturing process of Hellbeck array magnets, the pre-magnetized magnets are first placed into the assembly fixture according to requirements. After applying adhesive to the sides of the magnets to be assembled, the magnets are pushed and pressed together by a magnet assembly pushing mechanism. For extremely small magnets, the existing magnet assembly pushing mechanism cannot reliably and accurately push and press them together, and the magnets are easily damaged during the pushing process. Utility Model Content

[0004] The purpose of this invention is to provide a magnet assembly and pushing mechanism to solve the problem that existing magnet assembly and pushing mechanisms cannot reliably and accurately push and press together extremely small magnets.

[0005] To address the aforementioned problems, this utility model provides a magnet assembly and pushing mechanism. A jig plate is mounted on a base, and the jig plate has multiple magnet receiving slots. Magnets to be assembled are placed in these slots according to preset positions. The magnets to be assembled are elongated magnets. Each magnet receiving slot on the jig plate has a pushing slot located below the magnet at its bottom. The base also has a pushing assembly corresponding to the jig plate. The pushing assembly includes two pushing plates located on either side of the jig plate, and a third component that drives the two pushing plates to simultaneously move closer to or away from the jig plate. A driving assembly includes a plurality of push-joining plates slidably mounted on the push-joining plate, which can be inserted into the push-joining slots and push the magnets in the magnet receiving slots toward the central axis of the fixture plate; a push-joining vertical plate is provided on the upper side of the push-joining plate, and a push-joining buffer spring is also installed between the push-joining vertical plate and the push-joining insert plate. When the two push-joining plates approach the fixture plate at the same time, the push-joining insert plate moves toward the fixture plate with the push-joining plate and inserts into the push-joining slot. When the push-joining plate moves to a preset position, the push-joining vertical plate pushes and presses the magnets to be assembled onto the fixture plate through the push-joining buffer spring and the push-joining insert plate.

[0006] The magnet assembly and pushing mechanism provided by this utility model also has the following technical features: Furthermore, the first drive assembly adopts a parallel gripper-type pneumatic finger, and the two push plates are respectively fixedly connected to the two movable claws of the parallel gripper-type pneumatic finger.

[0007] Furthermore, the pushing plate is fixedly connected to the movable claw via a mounting vertical plate and a mounting horizontal plate. A limiting rod is also provided on the inner side of the mounting vertical plate, and a limiting plate corresponding to the limiting rod is also provided on the base.

[0008] Furthermore, the upper side of the push-together plate is provided with a push-together slide rail corresponding to each of the push-together inserts, and a push-together slider corresponding to the push-together slide rail is fixed on the push-together insert. Furthermore, the push-together vertical plate is provided with connecting holes corresponding to each of the push-together insert plates. The push-together connecting post passes through the connecting holes and is fixedly connected to the push-together insert plate. The push-together buffer spring is sleeved on the push-together connecting post. One end of the push-together buffer spring abuts against the push-together vertical plate and the other end abuts against the end of the push-together insert plate.

[0009] Furthermore, each of the magnet receiving slots has two pushing slots on both sides, and the two pushing slots are parallel and spaced apart; the end of the pushing plate has two pushing vertical plates corresponding to the pushing slots; the top surface of the pushing vertical plate is flush with the top surface of the magnet in the magnet receiving slot, or the top surface of the pushing vertical plate is higher than the top surface of the magnet in the magnet receiving slot.

[0010] Furthermore, each of the magnet receiving slots has a connecting slot on both sides that connects to the bottom ends of the two pushing slots, and the end of the pushing plate has a pushing connecting plate that connects to the bottom ends of the two pushing vertical plates and corresponds to the connecting slot.

[0011] The present invention has the following beneficial effects: The magnet assembly and pushing mechanism of this application has a pushing slot at the bottom of the magnet receiving groove on the jig plate. After the pushing plate is inserted into the pushing slot, it can reliably push the magnet in the magnet receiving groove to move towards the center of the jig plate. For magnets with extremely small size, especially magnets with extremely small thickness, the pushing plate can reliably abut and push the magnet to move, so that multiple magnets to be assembled can be reliably and accurately pushed and pressed together.

Detailed Implementation

[0013] 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.

[0014] like Figures 1 to 8 In the embodiment of the magnet assembly and pushing mechanism of this utility model shown, a jig plate 10 is installed on the base 100 of the magnet assembly and pushing mechanism. The jig plate 10 is provided with a plurality of magnet receiving slots 11. Magnets 101 to be pushed and assembled can be placed in the magnet receiving slots 11 according to preset positions, such as... Figure 1 , Figure 7 , Figure 8 As shown, the magnet 101 to be assembled is a long strip magnet. Three magnets 101 are placed at intervals in each magnet receiving slot 11. All three magnets 101 are long strips with the same height and length. The magnets 101 on both sides have the same width, while the magnet 101 in the middle has a slightly smaller width. All three magnets 101 are magnetized and the adjacent sides are glued. After the three magnets 101 are pushed together and pressed, the glue cures, which can bond and fix the three magnetized magnets 101 together. Specifically, the width of the magnet 101 is 0.4mm-0.7mm, the thickness (height) is 0.3mm-0.8mm, and the length is 8mm-10mm. That is, the magnet 101 is a very small long strip magnetic block that is already magnetized.

[0015] In the above embodiments of this application, each magnet receiving slot 11 on the jig plate 10 is further provided with a push-and-close slot 12 located below the magnet 101 at its bottom. The base 100 is also equipped with a push-and-close assembly 20 corresponding to the jig plate. The push-and-close assembly 20 includes two push-and-close plates 21 located on both sides of the jig plate 10, and a first drive assembly 22 that drives the two push-and-close plates 21 to move closer to or away from the jig plate 10 at the same time. Multiple push-and-close inserts 23 are slidably mounted on the push-and-close plates 21, which can be inserted into the push-and-close slots 12 and push the magnets 101 in the magnet receiving slots 11 toward the central axis of the jig plate 10. A push-and-close vertical push-and-close section is provided on the upper side of the push-and-close plate 21. A push-and-close buffer spring 25 is also installed between the plate 24, the push-and-close vertical plate 24 and the push-and-close insert plate 23. When the two push-and-close plates 21 on both sides of the fixture plate 10 move towards the fixture plate 10 at the same time, the push-and-close insert plate 23 moves towards the fixture plate 10 with the push-and-close plate 21 and inserts into the push-and-close slot 12. During the process of the push-and-close plate 21 moving towards the fixture plate, the push-and-close insert plate 23 pushes the magnets 101 on both sides towards the magnet 101 in the center. When the push-and-close plate 21 moves to the preset position, the push-and-close vertical plate 24 pushes and presses the multiple magnets 101 to be assembled onto the fixture plate 10 through the push-and-close buffer spring 25 and the push-and-close insert plate 23. After the glue cures, the three magnets 101 are bonded and fixed together.

[0016] In the above embodiment, the upper side of the jig plate 10 is also provided with an upper cover plate (not shown in the figure) to prevent the magnets 101 on both sides from flipping when they move toward the magnet 101 in the center, and to ensure that the magnets 101 on both sides can reliably slide toward the magnet 101 in the center under the push of the push-in plate 23. It can be understood that the upper cover plate only needs to prevent the magnets 101 from flipping during the movement, and its structure can be designed as needed, which will not be described in detail here.

[0017] The magnet assembly and pushing mechanism of this application has a pushing slot at the bottom of the magnet receiving groove on the jig plate. After the pushing plate is inserted into the pushing slot, it can reliably push the magnet in the magnet receiving groove to move towards the center of the jig plate. For magnets with extremely small size, especially magnets with extremely small thickness, the pushing plate can reliably abut and push the magnet to move, so that multiple magnets to be assembled can be reliably and accurately pushed and pressed together.

[0018] In one embodiment of this application, preferably, the first drive assembly 22 adopts a parallel gripper-type pneumatic finger, and two push plates 21 are respectively fixedly connected to the two movable claws of the parallel gripper-type pneumatic finger, thereby driving the two push plates 21 to move synchronously toward or away from the fixture plate 10. In one embodiment of this application, the parallel gripper-type pneumatic finger is selected as: finger cylinder HFD16X30 HFD16X30 (AirTAC).

[0019] In one embodiment of this application, preferably, the push plate 21 is fixedly connected to the movable claw by mounting vertical plate 221 and mounting horizontal plate 222. The inner side of the mounting vertical plate 221 is also provided with a limiting rod 223, and the base 100 is also provided with a limiting plate (not shown in the figure) corresponding to the limiting rod 223. This can limit the extreme position of the push plate 21 when it approaches the fixture plate 10, and prevent damage to the magnet when the control fails.

[0020] In one embodiment of this application, preferably, the upper side of the push-closing plate 21 is provided with a push-closing slide rail 211 corresponding to each push-closing insert plate 23, and a push-closing slider 212 corresponding to the push-closing slide rail 211 is fixed on the bottom surface of the push-closing insert plate 23, thereby enabling the push-closing insert plate 23 to reliably slide relative to the push-closing plate 21.

[0021] In one embodiment of this application, preferably, the push-closing vertical plate 24 is provided with connecting holes corresponding to each push-closing insert plate 23, the push-closing connecting post 241 passes through the connecting holes and is fixedly connected to the push-closing insert plate 23, and the push-closing buffer spring 25 is sleeved on the push-closing connecting post 241. One end of the push-closing buffer spring 25 abuts against the push-closing vertical plate 24 and the other end abuts against the end of the push-closing insert plate 23, thereby making the push-closing insert plate 23 and the push-closing plate 21 elastically connected. The pushing force of the push-closing plate 21 acting on the push-closing insert plate 23 is buffered by the push-closing buffer spring 25, which can effectively prevent damage to the magnet during the pushing process.

[0022] In one embodiment of this application, preferably, as shown below, Figure 7 , Figure 8 As shown, each magnet receiving slot 11 has two pushing slots 12 on each side, and the two pushing slots 12 are parallel and spaced apart; Figure 3 , Figure 4As shown, the end of the push-to-close plate 23 is provided with two push-to-close vertical plates 231, each corresponding to the push-to-close slot 12. That is, the two spaced-apart push-to-close vertical plates 231 simultaneously push one magnet 101 to move, so that the magnet is subjected to uniform force and moves smoothly. Preferably, the top surface of the push-to-close vertical plate 231 is flush with the top surface of the magnet to be assembled in the magnet receiving groove 11, or the top surface of the push-to-close vertical plate 231 is higher than the top surface of the magnet to be assembled in the magnet receiving groove 11. That is, the lower side of the push-to-close vertical plate 231 is inserted into the push-to-close slot 12, and the upper side of the push-to-close vertical plate 231 protrudes from the push-to-close slot 12 to push the magnet to be assembled in the magnet receiving groove 11 to move. For magnets with extremely small size, especially magnets with extremely small thickness, the push-to-close plates can reliably abut and push the magnet to move, so that multiple magnets to be assembled can be reliably and accurately pushed and pressed together.

[0023] In one embodiment of this application, preferably, each magnet receiving groove 11 has a connecting slot 13 on both sides that connects to the bottom of the two pushing slots 12, and the end of the pushing insert 23 is provided with a pushing connecting insert 232 that connects to the bottom of the two pushing vertical inserts 231 and corresponds to the connecting slot 13; thereby improving the structural strength of the pushing vertical insert 231 and making the pushing vertical insert 231 less prone to deformation and damage.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
