TECHNICAL FIELD
[0001] The present application relates to magnet assembly technology, in particular to a magnet assembly into magnet device. BACKGROUND
[0002] With the development of science and technology, magnetic materials have been widely used in motor, electroacoustic, automobile, electronic and other related industries. In the production and processing of electronic products, diaphragms (vibrating diaphragms of microphones, earphones, loudspeakers, etc.), electroacoustic equipment, some equipment requires magnets that are not rectangular or circular in shape, and the magnets need to be combined into the designed shape and size according to the design requirements of the product. Among them, the Halbach array is a combined magnet structure, which is an approximate ideal structure in engineering. Permanent magnets with different magnetization directions are arranged in a certain order, so that the magnetic field on one side of the array is significantly enhanced, while the magnetic field on the other side is significantly weakened. The goal is to generate the strongest magnetic field in the working area with the least amount of magnets.
[0003] In the processing of the Halbach array combined magnet, first, the already magnetized magnetic blocks are placed in the assembly jig according to the requirements. After the side of the magnetic block to be assembled is glued, the magnetic blocks are pushed together and pressed tightly together by the magnet assembly pushing mechanism. After the glue is cured, the magnetic blocks are bonded and fixed together to form a combined magnet.
[0004] For long strip-shaped magnets, when the magnets are pushed together and pressed, the magnets to be assembled need to be pushed together and close to each other along the width direction of the magnet first, and then pushed sideways along the length direction of the magnet to make the ends of the magnets flush. The top of the magnet is then pressed tightly, and after the glue is cured for a predetermined time, the assembled combined magnet is removed from the jig plate. The existing magnet assembly equipment cannot reliably and accurately push and press the small size magnets together during the above assembly operation, and the magnets are easily damaged during assembly. SUMMARY
[0005] The purpose of the present application is to provide a magnet assembly jig to solve the problem that the existing assembly jig cannot reliably and accurately push and press small size magnets together and bond and fix them.
[0006] To address the aforementioned problems, this invention provides a magnet assembly fixture. A fixture plate is mounted on a base, and the fixture plate has multiple magnet receiving slots. Magnets to be assembled, which are elongated magnets, can be placed in these slots according to preset positions. Each magnet receiving slot on the fixture plate has a push-and-close slot located below the magnet. A push-and-close assembly corresponding to the fixture plate is also mounted on the base. The push-and-close assembly includes two push-and-close plates located on opposite sides of the fixture plate, and a first drive assembly that drives the two push-and-close plates to simultaneously move closer to or away from the fixture plate.

The two push-and-close plates simultaneously push towards the central axis of the fixture plate. When the jig plate approaches, the push-close plate moves towards the jig plate and inserts into the push-close slot. When the push-close plate moves to a preset position, the push-close vertical plate pushes and presses the magnet to be assembled onto the jig plate through the push-close buffer spring and the push-close plate.

Furthermore, the side-push main shaft is provided with multiple annular grooves spaced axially, and a limiting snap ring is fitted in the annular groove. The side-push cross seat is installed between two of the limiting snap rings and can move between the two limiting snap rings. The side-push main shaft is also fitted with a side-push compression spring corresponding to each of the side-push cross seats. One end of the side-push compression spring abuts against the limiting snap ring, and the other end abuts against the side-push cross seat, so that the side-push vertical plate moves toward the magnet to be assembled.
[0013] Furthermore, the side-push assembly also includes a side-push base plate, on which a side-push slide rail parallel to the side-push main shaft is provided, and a side-push slider corresponding to the side-push slide rail is installed at the bottom of the side-push cross seat.

Detailed Implementation
[0023] 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 described in the embodiments of the present invention can be combined with each other.
[0024] like Figures 1 to 24 In the embodiment of the magnet assembly fixture of the present invention shown, a fixture plate 10 is mounted on the base 100 of the magnet assembly fixture. The fixture plate 10 is provided with a plurality of magnet receiving slots 11, in which magnets 101 to be assembled can be placed according to preset positions. Figure 3 , Figure 4 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.
[0025] 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.
[0026] The pushing assembly in 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 toward 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.
[0027] 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).
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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 4 As 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.
[0032] 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 plate 23 has a pushing connecting plate 232 that connects to the bottom of the two pushing vertical plates 231 and corresponds to the connecting slot 13; thereby improving the structural strength of the pushing vertical plates 231 and making the pushing vertical plates 231 less prone to deformation and damage.
[0033] In one embodiment of this application, one end of the magnet 101 abuts against the side wall of the magnet receiving groove 11. The bottom of each magnet receiving groove 11 on the jig plate 10 is also provided with a side push vertical hole 14 corresponding to the other end of the magnet 101. The side push vertical hole 14 penetrates through the jig plate 10. A side push assembly 30 corresponding to the jig plate 10 is also installed on the base 100. The side push assembly 30 includes a side push main shaft 31 installed on the base 100 and located on the lower side of the jig plate 10. A plurality of side push heads 32 corresponding to the side push vertical holes 14 are installed on the side push main shaft 31. The side push head 32 is provided with a side push vertical plate 321 that passes upward through the side push vertical hole 14. When the side push main shaft 31 moves axially, the side push vertical plate 321 can move with the side push main shaft 31 in the side push vertical hole 14 and abut against the end of the magnet 101 to be assembled.
[0034] In the above embodiments of this application, three magnets 101 are placed at intervals in the magnet receiving groove 11 on the jig plate 10. First, the magnets 101 on both sides are pushed and pressed together by the pushing assembly. After the three magnets 101 are pushed and pressed together, the side pushing main shaft 31 in the above embodiments of the magnet assembly side pushing mechanism of this application drives each side pushing vertical plate 321 to push and align the ends of the three magnets 101.
[0035] The magnet assembly side-push mechanism of this application has a side-push vertical hole corresponding to the end of the magnet in the bottom of the magnet receiving groove on the jig plate. The side-push vertical plate on the side-push head passes through the side-push vertical hole from bottom to top. When the side-push main shaft moves axially, each side-push vertical plate can move with the side-push main shaft in the side-push vertical hole and abut against the end of the magnet to be assembled. It can reliably and accurately push the magnet to be assembled into the magnet receiving groove, so that the ends of each magnet to be assembled are aligned.
[0036] In one embodiment of this application, preferably, the side push head 32 further includes a side push horizontal seat 322, and a side push vertical plate 321 is disposed at the top of the side push horizontal seat 322; the side push horizontal seat 322 is provided with a connecting horizontal hole, and the side push main shaft 31 passes through the connecting horizontal hole. The side push head 32 is connected to the side push main shaft 31 through the side push horizontal seat 322, so that the side push head 32 can move with the side push main shaft 31.
[0037] In one embodiment of this application, preferably, as shown below, Figure 5 , Figure 6As shown, the side-push main shaft 31 is provided with multiple annular grooves spaced axially. Limiting springs 311 are fitted into these grooves. A side-push cross seat 322 is installed between two limiting springs 311 and can move between them. The side-push main shaft 31 is also fitted with side-push compression springs 312 corresponding to each side-push cross seat 322. One end of each compression spring 312 abuts against a limiting spring 311, and the other end abuts against a side-push cross seat 322, causing the side-push vertical plate 321 to move towards the magnet to be assembled. Specifically, as... Figure 5 , Figure 6 As described above, a side-push compression spring 312 is sleeved on the side-push main shaft 31 on the right side of the side-push horizontal seat 322. The side-push compression spring 312 presses the left end of the side-push horizontal seat 322 against the limiting spring 311 on the left side. When the side-push main shaft 31 moves to the left, the side-push horizontal seat 322 moves to the left with the side-push main shaft 31. When the side-push vertical plate 321 at the top of the side-push horizontal seat 322 moves to the left and abuts against the right end of the magnet to be assembled, the side-push horizontal seat 322 no longer moves to the left with the side-push main shaft 31, and the side-push compression spring 312 is compressed. When the side-push main shaft 31 moves to the left to the preset position, the compressed side-push compression spring 312 presses the side-push vertical plate 321 against the right end of the magnet to be assembled. That is, the side-push pressing force at the end of the magnet to be assembled is provided by the side-push compression spring 312, which can reliably and accurately press the magnet to be assembled and avoid excessive pressure that could damage the magnet.
[0038] In one embodiment of this application, preferably, as shown below, Figures 2 to 4 As shown, the side push assembly 30 also includes a side push base plate 33, on which a side push slide rail 331 parallel to the side push main shaft 31 is provided. A side push slider 332 corresponding to the side push slide rail 331 is installed at the bottom of the side push cross seat 322, so that the side push head 32 can reliably move with the side push main shaft 31.
[0039] In one embodiment of this application, preferably, the side push base plate 33 is provided with two parallel side push slide rails 331, and the bottom of each side push cross seat 322 is equipped with two corresponding side push sliders 332, so that the side push head 32 can reliably move with the side push main shaft 31.
[0040] In one embodiment of this application, preferably, the side thrust assembly 30 further includes a side thrust cylinder 34 connected to one end of the side thrust main shaft 31, and the telescopic rod of the side thrust cylinder 34 is connected to the end of the side thrust main shaft 31 to drive the side thrust main shaft 31 to move axially.
[0041] In one embodiment of this application, a clamping assembly 40 corresponding to the fixture plate is also installed on the base 100. The clamping assembly 40 includes a top pressure plate 41 installed on the base 100 and located on the upper side of the fixture plate 10. The top pressure plate 41 is provided with a plurality of top pressure holes corresponding to the magnet receiving groove 11. A top pressure block 42 that can move up and down is installed in the top pressure hole. The lower end of the top pressure block 42 is provided with a top pressure head 43 that can protrude downward from the lower surface of the top pressure plate 41. The top pressure head 43 is also provided with a push-close groove 431 corresponding to the push-close insert plate and a side push groove 432 corresponding to the side push vertical plate. A top pressure horizontal plate 44 is also installed on the upper side of the top pressure plate 41. A top pressure spring 45 is installed between the upper side of each top pressure block 42 and the top pressure horizontal plate 44. The base 100 is also provided with a clamp 46 for pressing the top pressure plate 41 against the upper side of the fixture plate 10.
[0042] In the above-mentioned magnet assembly and clamping mechanism of this application, the jig plate 10 on which the magnets to be assembled are placed is first installed on the base 100, and then the pushing assembly 20, the side pushing assembly 30 and the clamping assembly 40 are installed on the base. During the pushing operation of the pushing assembly 20 and the side pushing operation of the side pushing assembly 30, the top pressure head 43 of the clamping assembly 40 abuts against the upper surface of the magnets to be assembled in each magnet receiving groove 11. At this time, the clamp 46 has not yet locked the top pressure plate 41 on the upper side of the jig plate. The pressure of the top pressure head 43 on the upper surface of the magnets to be assembled is the weight of the clamping assembly 40. The weight of the clamping assembly 40 is evenly distributed by each top pressure head 43 and acts on the upper surface of the magnets to be assembled in each magnet receiving groove 11 to prevent the magnets to be assembled from flipping during the pushing operation and the side pushing operation.
[0043] After the magnets to be assembled in the magnet receiving groove 11 of the jig plate 10 have completed the pushing and side-pushing operations, the pressing clamp 46 causes the top pressure plate 41 to move downward and stick to the jig plate 10 and hold it. After the bottom end of the top pressure head 43 touches the top surface of the magnet in the magnet receiving groove 11, the top pressure block 42 and the top pressure head 43 no longer move downward with the top pressure plate 41. The top pressure plate 44 moves downward with the top pressure plate 41, causing each top pressure spring 45 to be compressed. Each top pressure spring 45 provides pressure on the top surface of the magnet to be assembled by each top pressure block 42 and the top pressure head 43, which can reliably press the magnet to be assembled and avoid excessive pressure that could damage the magnet.
