Description

Technical Field

[0001] This invention relates to magnet assembly technology, and more particularly to a magnetizing device for magnet assembly. 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 (such as those for microphones, headphones, and speakers), and electroacoustic equipment, some equipment requires magnets that are not conventionally rectangular or circular in shape. Magnets need to be assembled 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 Hellbeck array combined magnets, the magnetized magnetic blocks are first placed into the assembly fixture as required, and then the magnetic blocks are pushed and bonded on the assembly fixture. For magnetized and small magnetic blocks, the existing magnetic block transfer / transfer device cannot reliably and accurately transfer the magnetic blocks, which can easily lead to problems such as magnetic block slippage and falling off. Summary of the Invention

Detailed Implementation

[0025] 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.

[0026] like Figures 1 to 33In the embodiment of the magnet assembly magnetization device of the present invention shown, a magazine 10, a jig plate 110, and a magnet transfer device 20 are mounted on the worktable 100 of the magnet assembly magnetization device. The magnet transfer device 20 is used to transfer the magnet 101 in the magazine 10 to the jig plate 110. The jig plate 110 is made of ferromagnetic material and has an assembly slot 111 for arranging and placing the magnets 101 to be assembled. The magnet transfer device 20 includes a transfer base plate 21 and a transfer slide plate 22. The transfer slide plate 22 is slidably mounted on the transfer base plate 21. A transfer translation push rod 23 (pneumatic push rod or electric push rod) is also mounted on the transfer base plate 21 to drive the transfer slide plate 22 to slide relative to the transfer base plate 21. The transfer slide plate 22 is slidably mounted on the transfer base plate 21. A groove 221 for accommodating a magnetic suction plate is provided on one side of the base plate 21. The magnetic suction plate is made of ferromagnetic material. A transfer plate 24 that closes the groove is also installed on the side of the transfer slide plate 22 opposite to the transfer base plate 21. A transfer block 241 corresponding to the magnet receiving groove on the magazine 10 is protruding on the bottom surface of the transfer plate 241. An opening groove 242 adapted to the shape of the elongated magnet is provided on the transfer block 241. The magnetic suction plate is used to attract the magnetized magnet in the magazine 10 to the opening groove 242 at the bottom of the transfer plate 24. The transfer translation push rod 23 (pneumatic push rod or electric push rod) can drive the transfer plate 24 to move towards the opening of the opening groove 242 so that the magnet 101 attracted to the bottom of the transfer plate 24 is separated from the magnet 101 in the magazine 10.

[0027] In one embodiment of this application, such as Figure 1 , Figure 3 As shown, the workbench 100 is equipped with two magazines 10, one magazine 10 is arranged vertically and the other magazine 10 is arranged horizontally. The workbench 100 is also equipped with two magnet transfer devices 20, which are used to transfer the magnets in the two magazines 10 to the assembly slots 111 of the jig plate 110.

[0028] In one embodiment of this application, such as Figure 2 As shown, three elongated magnets to be assembled need to be placed in the assembly slot 111 of the jig plate 110 according to the position shown in the figure. The middle magnet is fed by the horizontally arranged magazine 10, and the magnets on both sides are fed by the vertically arranged magazine 10. The following describes the working process of the magnet transfer device 20 by taking the magnet transfer device 20 transferring the magnet 101 in the vertically arranged magazine 10 to the assembly slot 111 of the jig plate 110 as an example: like Figure 4As shown, the transfer plate 24 of the magnet transfer device 20 moves to the upper side of the magazine 10 filled with magnets, and the horizontal movement of the transfer base plate 21 aligns the opening slot 242 on the transfer block 241 with the protruding magnet 101 on the top of the magazine 10. Then, the transfer base plate 21 moves downward, causing the transfer block 242 to move downward with the transfer plate 24, so that the magnet 101 to be transferred enters the opening slot 242. Since the groove 221 of the transfer slide plate 22 is equipped with a magnetic suction plate (iron plate or magnet), the top of the magnet 101 to be transferred can be attracted by the magnetic suction plate to the lower surface of the transfer plate 24 and located in the opening slot 242; Figure 4 As shown, the depth of the opening slot 242 in the vertical direction is less than or equal to the thickness of the magnet 101 to be transferred, meaning that only one magnet 101 to be transferred can be inserted into the opening slot 242. Specifically, only the magnet 101 protruding from the top of the magazine 10 enters the opening slot 242; the other magnets 101 remain inside the magazine 10. Because the magnets 101 to be transferred are magnetized, they attract each other. After the magnet 101 protruding from the top of the magazine 10 enters the opening slot 242, it is then transferred horizontally. The push rod 23 (pneumatic push rod or electric push rod) drives the transfer plate 24 to move towards the opening direction of the opening slot 242, so that the magnet 101 in the opening slot 242 moves horizontally with the transfer plate 24, so that the magnet 101 in the opening slot 242 is separated from the other magnets 101 to be transferred in the magazine 10. Thus, the magnets 101 to be transferred can be reliably separated from the magazine 10. During the transfer process, the position of the magnet 10 will not move and the attitude will not change. The magnet can be reliably attracted to the opening slot at the bottom of the transfer plate 24 and will not fall off.

[0029] In the above embodiments of this application, the magnetic suction plate installed in the groove 221 of the transfer slide plate 22 is an iron plate, and the transfer base plate 21, transfer slide plate 22, transfer plate 24, etc. are all made of non-ferromagnetic materials that cannot be attracted by magnets, such as aluminum alloy; the fixture plate 110 is also made of iron plate of the same material as the magnetic suction plate; when the magnet transfer device 20 transfers the magnet 101 to the fixture plate 110 and the transfer plate 24 is aligned with the fixture plate 110, the transfer base plate 21 is moved downward so that the bottom of the transfer block 241 on the lower side of the transfer plate 24 approaches the upper surface of the fixture plate 110. At this time, the magnetic suction plate in the groove 221 of the fixture plate 110 is attracted by the magnetic suction plate 221. The suction plate magnetically attracts the magnet in the opening slot 242. However, because the lower surface of the magnet 101 in the opening slot 242 is in direct contact with the upper surface of the fixture plate 110, the upper surface of the magnet 101 in the opening slot 242 is attracted to the lower surface of the transfer plate 24, and the distance between the magnet 101 and the magnetic suction plate in the groove 221 is the thickness of the transfer plate 24, the attraction force of the fixture plate 110 on the magnet 101 is greater than the attraction force of the magnetic suction plate on the magnet 101. Thus, the magnet 101 to be transferred in the opening slot 252 is transferred and attracted to the assembly groove 111 on the fixture plate 110, realizing the reliable transfer of the magnet 101.

[0030] In one embodiment of this application, preferably, as shown below, Figure 8 As shown, a transfer slide rail 211 is also installed on the transfer base plate 21, and a transfer slider 221 adapted to the transfer slide rail 211 is provided on the transfer slide plate 22, so that the transfer slide plate 22 can reliably slide relative to the transfer base plate 21. Preferably, as shown... Figure 9 , Figure 10 As shown, a plurality of transfer blocks 241 are protruding on the bottom surface of the transfer plate 24, and each transfer block 241 is provided with an opening slot 242, the opening directions of the opening slots 242 being the same; the number of transfer blocks 251 is the same as the number of magnet receiving slots on the magazine 10, thereby allowing multiple magnets 101 provided by the magazine 10 to be transferred simultaneously. Preferably, the lower inner edge of the opening slot 242 is also provided with a feeding guide slope, so that the magnet 101 can accurately enter the opening slot 242. The transfer plate 24 at the bottom of the opening slot 242 is also provided with a vent hole, so that the air in the slot can be discharged in time when the magnet 101 enters the opening slot 242, and the magnet 101 can be prevented from being attracted to the opening slot 242 by negative pressure, which would affect the magnet 101 detaching from the transfer plate 24 during material release.

[0031] In one embodiment of this application, preferably, as shown below, Figures 9 to 12 As shown, a downwardly extending limiting plate 212 is also installed at the end of the transfer base plate 21 away from the transfer translation push rod 23. The limiting plate 212 is provided with a limiting hole. The end of the transfer slide plate 22 is provided with a connecting hole corresponding to the limiting hole. A limiting pin 213 is installed in the connecting hole of the transfer slide plate 22 and passes through the limiting hole. A compression spring is also sleeved on the limiting pin 213 between the limiting plate 212 and the transfer slide plate 22. The limiting plate 213 makes the transfer slide plate 22 reliably positioned at the left end of the transfer base plate 21. The compression spring can play a buffering role between the limiting plate 213 and the transfer slide plate 22.

[0032] In one embodiment of this application, preferably, as shown below, Figure 6 As shown, the magnet transfer device 20 also includes a mounting vertical plate 251 and a vertical sliding plate 252. The vertical sliding plate 252 is slidably mounted on the mounting vertical plate 251. The mounting vertical plate 251 is also provided with a transfer lifting push rod 253 (pneumatic push rod or electric push rod) that drives the vertical sliding plate 252 to slide up and down. The transfer base plate 21 is mounted on the bottom end of the vertical sliding plate 252, thereby driving the transfer base plate 21 to move up and down.

[0033] In one embodiment of this application, preferably, the mounting vertical plate 251 is further provided with a vertical slide rail 254, and the vertical slide plate 252 is provided with a vertical slider 255 adapted to the vertical slide rail 254, so that the vertical slide plate 252 can reliably slide up and down relative to the mounting vertical plate 251. Preferably, as Figure 6 , Figure 11As shown, a vertical buffer spring 256 is also provided between the mounting plate 251 and the vertical slide plate 252.

[0034] In one embodiment of this application, preferably, as shown below, Figure 4 , Figure 5 As shown, the magnet transfer device 20 also includes a transfer base 26, on which a transfer feeding slide plate 27 is slidably mounted. A mounting vertical plate 251 is connected to the transfer feeding slide plate 27 via a connecting horizontal plate 271. A transfer feeding assembly for driving the transfer feeding slide plate 27 to move horizontally on the transfer base 26 is also mounted on the transfer base 26. Preferably, the transfer feeding assembly includes a transfer mounting plate 28, a motor 281, a drive pulley 282, a driven pulley 283, and a belt 284. The motor 281 is mounted on the transfer mounting plate 28, the drive pulley 282 is mounted on the output shaft of the motor 281, and the driven pulley 283 is rotatably mounted on the transfer mounting plate 28. A belt 284 is provided between the drive pulley 282 and the driven pulley 283. The belt 284 is preferably a synchronous belt. The transfer feeding slide plate 27 is fixedly connected to the belt 284 via a connecting plate 272, thereby driving the transfer feeding slide plate 27 to move back and forth.

[0035] In one embodiment of this application, preferably, as shown below, Figure 1 As shown, two magazines 10 are mounted on the worktable 100, one magazine 10 arranged vertically and the other magazine 10 arranged horizontally. Figure 13 , Figure 16 , Figure 17 As shown, a magazine 10 arranged vertically is installed on the workbench 100. The magazine 10 is provided with a magnet receiving groove 11 arranged vertically and open at the top. The magnet receiving groove 11 is filled with a long strip magnet 101 to be assembled that can slide upward. The magazine 10 is also provided with a lifting slide groove 12 corresponding to the magnet receiving groove 11. The lower end of the lifting slide groove 12 is open. A lifting plate 31 is also installed on the workbench 100. The lifting plate 31 is provided with a pusher plate 32 that can be inserted into the lifting slide groove 12 through the lower end opening of the lifting slide groove 12. When the lifting plate 31 moves upward, the pusher plate 32 pushes the magnet 101 in the magnet receiving groove 11 upward. This application cleverly provides a lifting groove 22 with an opening at the bottom on the lower side of the magazine, and a pusher plate 32 that can be inserted into the lifting groove 22 on the lifting plate 31, which can reliably and stably push the magnets 101 in the magazine 10 upward in sequence to supply materials for magnet assembly.

[0036] In one embodiment of this application, preferably, as shown below, Figure 21 , Figure 22As shown, the lifting plate 31 has mounting holes 311, and the pusher plate 32 has guide vertical holes corresponding to the mounting holes 311. The pusher plate 32 is connected to the lifting plate 31 through a positioning pin 321 passing through the guide vertical holes. A buffer spring 322 is also installed between the pusher plate 32 and the lifting plate 31 to make the pusher plate 32 and the lifting plate 31 elastically connected. Figure 22 As shown, the buffer spring 322 is a compression spring. The lower side of the pusher plate 32 and the upper side of the lifting plate 31 are respectively provided with spring mounting holes. The buffer spring 322 is installed in the spring mounting holes. When the upper surface of the pusher plate 32 does not contact the magnet 101 in the magnet receiving groove 11, the upper surface of the pusher plate 32 contacts the pin of the positioning pin 321 under the action of the buffer spring 322. When the upper surface of the pusher plate 32 contacts the magnet 101 in the magnet receiving groove 11, the buffer spring 322 can be compressed. This elastic connection structure of the pusher plate 32 can prevent the pusher plate 32 from excessively squeezing the magnet 101 and causing the magnet to break.

[0037] In one embodiment of this application, preferably, as shown below, Figures 16 to 18 As shown, the magazine 10 is provided with two magnet receiving slots 11 arranged in the front-back direction. The pusher plate 31 passes through the lifting slide 12 in the front-back direction of the magazine 10 and can simultaneously push the magnets 101 in the two magnet receiving slots 11 arranged in the front-back direction upward. Thus, one pusher plate 32 can simultaneously push the magnets 101 in the magnet receiving slots 11 arranged in the front-back direction of the magazine 10 upward. The magazine 10 is provided with multiple sets of magnet receiving slots 11 arranged in the left-right direction. Each set of magnet receiving slots 11 is provided with one lifting slide 12. Multiple pusher plates 32 are installed on the lifting plate 31 arranged in the left-right direction. Each pusher plate 32 corresponds to one lifting slide 12. Thus, when the lifting plate 31 moves upward, it can simultaneously push the magnets in multiple sets of magnet receiving slots 11 upward.

[0038] In one embodiment of this application, preferably, as shown below, Figures 16 to 18 As shown, the magazine 10 includes a magazine base plate 13 located in the middle and magazine cover plates 14 located on the front and rear sides of the magazine base plate 13. Magnet receiving slots 11 are opened on the front and rear sides of the magazine base plate 13. The magazine cover plate 14 is a flat plate, which facilitates the manufacture and assembly of the magazine.

[0039] In one embodiment of this application, preferably, as shown below, Figures 19 to 21 As shown, the lifting plate 31 is also provided with a vertical through hole 312 that is adapted to the bottom of the magazine 10, so that the lifting plate 31 can reliably move upward relative to the magazine 10.

[0040] In one embodiment of this application, preferably, as shown below, Figure 13As shown, a magazine fixing plate 15 is installed on the upper side of the workbench 100, and the top of the magazine 10 is connected to the magazine fixing plate 15.

[0041] In one embodiment of this application, preferably, as shown below, Figures 13 to 15 , Figure 19 , Figure 20 As shown, a lifting assembly for driving the lifting plate 31 to move up and down is also installed on the worktable 100; specifically, the lifting assembly can adopt a linear lifting mechanism such as a linear stepper motor or an electric push rod. In one embodiment of this application, the lifting assembly adopts a combination structure of a servo motor and a linear slide module, using a Panasonic 100W servo motor MSMF012L1U2M and a HIWIN KK40-200A1-F0 linear slide module. The linear slide module converts the rotational motion of the servo motor into linear motion. This combination can accurately control the upward movement distance of the lifting plate each time according to the thickness of the magnet, especially for feeding and pushing magnets with smaller thicknesses.

[0042] In one embodiment of this application, preferably, as shown below, Figures 13 to 15 , Figure 19 , Figure 20 As shown, the lifting assembly is hidden on the lower side of the workbench 100, and the magazine 10 is installed on the upper side of the workbench 100, making the equipment layout reasonable and the appearance simple. The lifting slider of the lifting assembly is equipped with a lifting horizontal plate 33, which is connected and fixed to the lifting plate 31 through two lifting vertical plates 34. The workbench 100 is provided with through holes corresponding to the lifting vertical plates 34. The lifting vertical plates 34 pass through the through holes and their upper ends are connected to the lifting plate 31, thereby enabling the lifting assembly to drive the lifting plate 31 to move up and down.

[0043] In one embodiment of this application, preferably, as shown below, Figures 13 to 15 , Figure 19 , Figure 20 As shown, a guide plate 35 corresponding to the lifting plate 34 is also installed on the worktable 100. A slide rail is installed on the guide plate 35, and a slider adapted to the slide rail is installed on the lifting plate 34, so that the lifting plate 31 can move up and down reliably.

[0044] In one embodiment of this application, preferably, as shown below, Figure 1 As shown, two magazines 10 are mounted on the worktable 100, one magazine 10 arranged vertically and the other magazine 10 arranged horizontally. Figure 3 , Figure 23 , Figure 25As shown, a magazine 10 arranged horizontally is mounted on the workbench 100. The magazine 10 is filled with elongated magnets 101. The magazine 10 has a horizontally arranged magnet receiving slot, which contains multiple magnets 101, allowing the magnets 101 to slide horizontally within the slot. The magazine 10 also has a translational slide 16 corresponding to the magnet receiving slot, with a feeding plate 41 inserted into the translational slide 16 to horizontally push the magnets 101. Figure 23 , Figure 25 As shown, when the feeding plate 41 moves from left to right in the translation chute 16, it can push the magnet 101 filled in the magnet receiving slot to the right; a vertical distribution plate 50 is also installed at the discharge end on the right side of the magazine 10. The vertical distribution plate 50 is provided with a vertical distribution slot 501 corresponding to the outlet of the magnet receiving slot. When the feeding plate 41 moves towards the vertical distribution plate 50 in the translation chute 16, it can push the magnet 101 in the magnet receiving slot towards the vertical distribution slot 501; a distribution and pushing vertical plate 61 is also installed on the vertical distribution plate 50 to push the magnet 101 in the vertical distribution slot 501 upward along the vertical distribution slot 501.

[0045] In the above embodiments of this application, the elongated magnets filling the magnet receiving slots of the magazine 10 are magnetized, and each magnet 101 is sequentially loaded into the magnet receiving slots according to a predetermined posture and can attract each other, such as... Figure 23 , Figure 25 As shown, the feeding plate 41 pushes all the magnets in the magnet receiving groove to the right, so that the rightmost magnet leaves the magnet receiving groove and enters the vertical distribution groove 501 on the vertical distribution plate 50. Then, the distribution pushing vertical plate 61 pushes the magnet 101 that has entered the vertical distribution groove 501 upward. It can be understood that the width of the vertical distribution groove 501 is greater than the width of the magnet 101 but less than 1.5 times the width of the magnet 101, so that only one magnet 101 can slide up and down in the vertical distribution groove 501. The width of the vertical distribution groove 501 also needs to ensure that the magnet 101 will not flip over during the upward movement. Under the lifting action of the material distribution and pushing vertical plate 61, the magnet 101 in the vertical material distribution groove 501 is separated from the magnet 101 in the magnet receiving groove and moves upward along the vertical material distribution groove 501. The material distribution and pushing vertical plate 61 can push the magnet 101 in the vertical material distribution groove 501 upward out of the vertical material distribution plate 50, thereby efficiently and reliably supplying materials for magnet assembly.

[0046] like Figure 29 As shown in the figure, two magnets 101 are displayed in the same vertical material distribution groove 501. The position of the magnet 101 located on the lower side is the position when the magnet 101 enters the vertical material distribution groove 501 and has not yet been pushed upward; the position of the magnet 101 located on the upper side is the position after the magnet 101 is lifted and pushed by the material distribution pushing vertical plate 61.

[0047] In one embodiment of this application, preferably, the vertical distribution plate 50 is further provided with a magnetic suction block 53 corresponding to the vertical distribution groove 501. The magnetic suction block 53 is used to draw the magnet 101 in the magnet receiving groove of the magazine 10 into the vertical distribution groove 501. Specifically, when using the horizontally arranged magazine 10 for feeding, firstly, the magnet 101 to be assembled is filled into the magnet receiving groove of the magazine 10 and the magazine 10 is installed and fixed. Then, the magnet 101 filled in the magnet receiving groove is pushed together towards the outlet end of the magazine by the feeding plate 41. Figure 25 As shown, when the magnet 101 filled in the magnet receiving tank moves to the right and approaches the vertical distribution plate 50, the magnetic attracting block 53 attracts the magnet 101 filled in the magnet receiving tank into the vertical distribution tank 501; as Figure 23 , Figure 24 As shown, the magnetic block 53 is a long cylindrical shape. The magnetic block 53 is a magnet, and its polarity is arranged to attract the magnet 101. Alternatively, the magnetic block 53 may be made of ferromagnetic materials such as iron blocks. The magnet 101 has a width of 0.4mm-0.7mm, a thickness of 0.3mm-0.8mm, and a length of 8mm-10mm. That is, the magnet 101 is a very small, elongated magnetic block and is already magnetized. When feeding begins, the feeding plate 41 moves the magnet 101 filled in the magnet receiving groove to the right, closer to and vertically aligned with the distributing plate 50. Then, the magnetic block 53 pulls the magnet 101 into the vertical distributing groove 501. It can be understood that the magnet receiving groove... The magnets 101 filled in the storage tank move to the right together under the magnetic attraction of the magnetic block 53, and the rightmost magnet 101 enters the vertical material distribution tank 501. Then, the material distribution and pushing vertical plate 61 pushes the magnets 101 in the vertical material distribution tank 501 upward. After the material distribution and pushing vertical plate 61 moves upward to complete the material distribution and pushing, the material distribution and pushing vertical plate 61 moves up and down to reset. Under the magnetic attraction of the magnetic block 53, the magnets 101 filled in the magnet receiving tank move to the right again, and the rightmost magnet 101 enters the vertical material distribution tank 501. This cycle repeats to realize the horizontal feeding, vertical distribution, and vertical pushing of the magnets 101.

[0048] In one embodiment of this application, preferably, the horizontally arranged magazine 10 is provided with a plurality of parallel magnet receiving slots, each of the magnet receiving slots is respectively provided with a translation slide 16, each translation slide 16 is respectively inserted into the feeding plate 41, and each feeding plate 41 is fixedly connected to the translation push plate 42.

[0049] In one embodiment of this application, preferably, as shown below, Figure 25 , Figure 26As shown, the lower end of each feeding plate 41 is fixedly connected to the translation push plate 42. The translation push plate 42 is mounted on the translation slider of the translation cylinder 43 (pneumatic push rod or electric push rod), thereby driving the feeding plate 41 to move within the translation groove 16 via the translation cylinder 43. Preferably, a lifting cylinder 44 (pneumatic push rod or electric push rod) is also mounted on the translation slider of the translation cylinder 43 (pneumatic push rod or electric push rod), and the translation push plate 42 is fixedly connected to the lifting slider of the lifting cylinder 44. In this design, the translation cylinder can push the lifting cylinder and the translation push plate to move horizontally, and the lifting cylinder can push the translation push plate to move up and down, so that the translation push plate can be inserted upward into the translation groove or disengaged downward from the translation groove.

[0050] In one embodiment of this application, a plurality of vertical material distribution slots 501 are provided on the vertical material distribution plate 50 corresponding to each of the magnet receiving slots. Each vertical material distribution slot 501 is respectively provided with a material distribution pushing vertical plate 61. The bottom end of each material distribution pushing vertical plate 61 is fixedly connected to a material distribution pushing horizontal plate 62. The material distribution pushing horizontal plate 62 is installed on the lifting slider of the material distribution pushing cylinder 63 (pneumatic push rod or electric push rod). Thus, the material distribution pushing vertical plate 61 can be driven to move up and down by the material distribution pushing cylinder 63.

[0051] In one embodiment of this application, preferably, the vertical dividing plate 50 includes a first dividing plate 51 and a second dividing plate 52 arranged along the moving direction of the feeding plate 16. The first dividing plate 51 is provided with a first opening groove 511 corresponding to the magnet receiving groove. The first opening groove 511 penetrates the first dividing plate 51 in the vertical direction. The second dividing plate 52 is provided with an insert block 521 for inserting into the first opening groove 511 on the side near the first dividing plate 51. After the first dividing plate 51 and the second dividing plate 52 are assembled, a vertical dividing groove 501 is formed between the end of the insert block 521 and the first opening groove 511, thereby facilitating the processing and manufacturing of the vertical dividing plate 50. As mentioned above, the width of the magnet 101 is 0.4mm-0.7mm, and the width of the vertical dividing groove 501 is slightly larger than the width of the magnet 101. The vertical dividing plate 50 is set as a split structure to facilitate the processing and formation of the above-mentioned vertical dividing groove 501.

[0052] In one embodiment of this application, preferably, the insert block 521 is further provided with a lifting opening slide groove 522 that extends vertically through the second material distribution plate 52. The lifting opening slide groove 522 is perpendicular to and communicates with the vertical material distribution groove 501. The material distribution pushing vertical plate 61 is inserted into the lifting guide groove 522 and extends to the vertical material distribution groove 501 on the side near the first material distribution plate 51 to push the magnet in the vertical material distribution groove 501 upward. This structure can be designed according to the requirements of the thickness of the material distribution pushing vertical plate 50 and the width of the lifting guide groove 522, so that the material distribution pushing vertical plate 61 has sufficient structural strength and avoids deformation and wear of the material distribution pushing vertical plate 61.

[0053] In one embodiment of this application, such as Figure 31 , Figure 32 As shown, the insert block 521 also has two parallel and spaced lifting opening slides 522. Each lifting opening slide 522 is equipped with a material distribution and pushing vertical plate 61. The material distribution and pushing vertical plates 61 in the two lifting opening slides 522 move upward synchronously to push the magnet in the vertical material distribution groove 501 upward. The magnet 101 in the vertical material distribution groove 501 is pushed upward synchronously, stably and reliably by the two material distribution and pushing vertical plates 61.

[0054] In one embodiment of this application, preferably, as shown below, Figures 23 to 29 As shown, a vertical dividing plate 50 is mounted on a dividing base 54. The dividing base 54 is provided with a vertical slide rail 55, and the vertical dividing plate 50 is provided with a slider 56 adapted to the vertical slide rail 55. The vertical dividing plate 50 is also provided with a connecting vertical hole. The vertical dividing plate 50 is connected to the dividing base 54 through a connecting limiting pin 57 passing through the connecting vertical hole to prevent the vertical dividing plate 50 from detaching from the dividing base 54 upwards. A dividing spring 58 is also provided between the vertical dividing plate 50 and the dividing base 54. The bottom end of the dividing spring 58 abuts against the upper side of the dividing base 54, and the top end of the dividing spring 58 abuts against the lower side of the vertical dividing plate 50, so that the upper side of the vertical dividing plate 50 abuts against the pin cap of the connecting limiting pin 57. This elastic mounting structure of the vertical dividing plate 50 allows the vertical dividing plate 50 to move downwards relative to the dividing base 54 when it is pressed downwards. Specifically, as described above, the magnet 101 in this application is magnetized and has magnetic properties, the magnetic block 53 is a magnet or a ferromagnetic material that can be attracted by a magnet, and other components are made of non-ferromagnetic materials that cannot be attracted by a magnet, such as aluminum alloy. In this embodiment of the application, when the material distribution and pushing vertical plate 61 moves upward, it can push the magnet 101 in the vertical material distribution groove 501 upward, and push the magnet 101 upward until its upper surface is flush with the upper surface of the vertical material distribution plate 50, so that the magnet 101 is still located in the vertical material distribution groove 501 and its bottom is supported by the material distribution and pushing vertical plate 61, thereby ensuring that the magnet 101 will not shake, slide, or flip. When the robotic arm (transfer plate) with the ability to attract and move the magnet 101 moves to the upper side of the vertical distribution trough 501 and aligns with the magnet 101 in the vertical distribution trough 501, the robotic arm (transfer plate) first moves downward to contact the upper surface of the vertical distribution plate 50, so that the upper surface of the magnet 101 is attracted to the transfer plate. Then, it presses the vertical distribution plate 50 to move downward. Since the bottom of the magnet 101 is supported by the distribution push vertical plate 30, the magnet 101 will not move downward with the vertical distribution plate 20, so that the magnet 101 is separated from the vertical distribution trough 501 of the vertical distribution plate 50. This makes the positioning of the magnet 101 accurate during the transfer process.
