A magnet assembly side-pushing mechanism

Abstract

This utility model relates to a magnet assembly side-push mechanism. A jig plate is mounted on a base, and the jig plate has multiple magnet receiving slots. Each magnet receiving slot on the jig plate has a side-push vertical hole at its bottom, corresponding to the end of the magnet, which penetrates the jig plate. A side-push assembly corresponding to the jig plate is also mounted on the base. The side-push assembly includes a side-push main shaft, on which multiple side-push heads are mounted. Each side-push head has a side-push vertical plate that extends upward through the side-push vertical hole. The magnet assembly side-push mechanism of this application, by having side-push vertical holes corresponding to the ends of the magnets at the bottom of the magnet receiving slots on the jig plate, allows the side-push vertical plates on the side-push heads to pass through the side-push vertical holes 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 within the side-push vertical hole and abut against the end of the magnet to be assembled. This reliably and accurately pushes the magnet to be assembled into the magnet receiving slot, aligning the ends of each magnet.

Description

Technical Field

[0001] This utility model relates to magnet assembly technology, and in particular to a magnet assembly side-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 processing of the Hellbeck array combined magnet, the magnetized blocks are first placed into the assembly fixture as required. After applying glue to the side of the blocks to be assembled, the magnetic fields are pushed and pressed together by the magnet assembly pushing mechanism. After the glue cures, the blocks are bonded together to form a combined magnet.

[0004] For long, strip-shaped magnets, when pushing and pressing the magnets together, the magnets to be assembled need to be pushed close together first, and then pushed laterally along the length of the magnets to make the ends of each magnet flush. Existing magnet assembly equipment cannot reliably and accurately push the ends of the magnets to be assembled laterally. Utility Model Content

[0005] The purpose of this invention is to provide a magnet assembly side-pushing mechanism to solve the problem that existing magnet assembly equipment cannot reliably and accurately push the end of the magnet to be assembled.

[0006] To solve the above problems, this utility model provides a magnet assembly side-push mechanism. A jig plate is installed on the base, and the jig plate is provided with multiple magnet receiving slots. Magnets to be assembled can be placed in the magnet receiving slots according to preset positions. The magnets to be assembled are elongated magnets. One end of the magnet abuts against the side wall of the magnet receiving slot. The bottom of each magnet receiving slot on the jig plate is also provided with a side-push vertical hole corresponding to the other end of the magnet. The side-push vertical hole penetrates the jig plate. The base is also equipped with a side-push assembly corresponding to the jig plate. The side-push assembly includes a side-push spindle installed on the lower side of the jig plate. The side-push spindle is equipped with a plurality of side-push heads that correspond to the side-push vertical holes respectively. The side-push heads are provided with side-push vertical plates that pass upward through the side-push vertical holes. When the side-push spindle moves axially, the side-push vertical plates can move with the side-push spindle in the side-push vertical holes and abut against the end of the magnet to be assembled.

[0007] The magnet assembly side-pushing mechanism provided by this utility model also has the following technical features: Furthermore, the side push head also includes a side push horizontal seat, and the side push vertical plate is disposed at the top of the side push horizontal seat; the side push horizontal seat is provided with a connecting horizontal hole, the side push main shaft passes through the connecting horizontal hole, and the side push head is connected to the side push main shaft through the side push horizontal seat. 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.

[0008] 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.

[0009] Furthermore, the side push base plate is provided with two parallel side push slide rails, and the bottom of each side push cross seat is equipped with two corresponding side push sliders.

[0010] Furthermore, the side thrust assembly also includes a side thrust cylinder connected to one end of the side thrust main shaft, and the telescopic rod of the side thrust cylinder is connected to the end of the side thrust main shaft.

[0011] The present invention has the following beneficial effects: The magnet assembly side-push mechanism of this application opens a side-push vertical hole corresponding to the end of the magnet at 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. Attached Figure Description

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 9 In the embodiment of the magnet assembly side-pushing mechanism of this utility model shown, a jig plate 10 is installed on the base 100 of the magnet assembly side-pushing mechanism. The jig plate 10 is provided with multiple magnet receiving slots 11. Magnets 101 to be pushed and assembled can be placed in the magnet receiving slots 11 according to preset positions. The magnets to be assembled are elongated magnets, such as... Figure 1 , Figure 8 , Figure 9 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, 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. The base 100 is also equipped with a side push assembly 30 corresponding to the jig plate 10. 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. The side push main shaft 31 is equipped with a plurality of side push heads 32 respectively corresponding to the side push vertical holes 14. 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.

[0016] 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 (not shown in the figure). It can be understood that the structure of the pushing assembly that pushes and presses the three magnets 101 together can be designed as needed, and will not be described in detail here. 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.

[0017] 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.

[0018] 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.

[0019] In one embodiment of this application, preferably, as 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.

[0020] In one embodiment of this application, preferably, as 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.

[0021] 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.

[0022] 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.

[0023] 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.
