Description

Technical Field

[0001] This utility model relates to magnet assembly technology, and in particular to a transfer 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. Depending on the product design requirements, magnets need to be combined into a specific shape and size. 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, when placing the magnetized magnetic blocks into the assembly fixture as required, the magnetic blocks first need to be transferred from the feeding spring to 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. Utility Model Content

[0004] The purpose of this invention is to provide a transfer device for assembling magnets, which solves the problem that magnets are prone to sliding or falling off during the transfer of existing magnets.

[0005] To address the aforementioned problems, this utility model provides a magnet assembly transfer device, comprising a transfer base plate and a transfer slide plate. The transfer slide plate is slidably mounted on the transfer base plate. A first pneumatic push rod is also mounted on the transfer base plate to drive the transfer slide plate to slide relative to the transfer base plate. A groove for accommodating a magnetic suction plate is formed on the side of the transfer slide plate opposite to the transfer base plate. The magnetic suction plate is made of ferromagnetic material. A transfer plate that closes the groove is also mounted on the side of the transfer slide plate opposite to the transfer base plate. A transfer block is protruding on the bottom surface of the transfer plate, and an opening groove adapted to the shape of a long strip magnet is formed on the transfer block. The magnetic suction plate is used to attract the magnetized magnet into the opening groove at the bottom of the transfer plate. The first pneumatic push rod can drive the transfer plate to move towards the opening of the opening groove, thereby separating the magnet attracted to the transfer plate from adjacent magnets.

[0006] The magnet assembly transfer device provided by this utility model also has the following technical features:

[0007] Furthermore, a transfer slide rail is also installed on the transfer base plate, and a transfer slider adapted to the transfer slide rail is provided on the transfer slide plate.

[0008] Furthermore, a plurality of transfer blocks are protruding on the bottom surface of the transfer plate, and each transfer block is provided with an opening groove; the opening direction of each opening groove is the same.

[0009] Furthermore, a downwardly extending limiting plate is installed at the end of the transfer base plate opposite to the first pneumatic push rod. The limiting plate is provided with a limiting hole, and the end of the transfer slide plate is provided with a connecting hole corresponding to the limiting hole. A limiting pin is installed in the connecting hole of the transfer slide plate and passes through the limiting hole. A compression spring located between the limiting plate and the transfer slide plate is also sleeved on the limiting pin.

[0010] Furthermore, it also includes a mounting vertical plate and a vertical sliding plate, the vertical sliding plate being slidably mounted on the mounting vertical plate, the mounting vertical plate being provided with a second pneumatic push rod for driving the vertical sliding plate to slide up and down, and the transfer base plate being mounted on the bottom end of the vertical sliding plate.

[0011] Furthermore, the mounting plate is also provided with a vertical slide rail, and the vertical slide plate is provided with a vertical slider that is adapted to the vertical slide rail.

[0012] Furthermore, a vertical buffer spring is provided between the mounting plate and the vertical sliding plate.

[0013] Furthermore, it also includes a base, on which a feeding slide is slidably mounted. The mounting vertical plate is connected to the feeding slide via a connecting horizontal plate. The base is also equipped with a feeding assembly that drives the feeding slide to move horizontally on the base.

[0014] Furthermore, the feeding assembly includes a mounting plate, a motor, a drive pulley, a driven pulley, and a belt. The motor is mounted on the mounting plate, the drive pulley is mounted on the output shaft of the motor, the driven pulley is rotatably mounted on the mounting plate, the belt is provided between the drive pulley and the driven pulley, and the feeding slide is fixedly connected to the belt.

[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 in the embodiments of the present invention can be combined with each other.

[0026] like Figures 1 to 9 In the embodiment of the magnet assembly transfer device of this utility model shown, the magnet assembly transfer device includes a transfer base plate 11 and a transfer slide plate 12. The transfer slide plate 12 is slidably mounted on the transfer base plate 11. A first pneumatic push rod 13 is also mounted on the transfer base plate 11 to drive the transfer slide plate 12 to slide relative to the transfer base plate 11. A groove 121 for accommodating a magnetic suction plate is formed on the side of the transfer slide plate 12 away from the transfer base plate 11. The magnetic suction plate is made of ferromagnetic material. A transfer plate 14 with a closed groove 121 is also installed on the side opposite to the transfer base plate 11. A transfer block 15 is protruding on the bottom surface of the transfer plate 14. An opening groove 151 adapted to the shape of the elongated magnet is opened on the transfer block 15. The magnetic suction plate is used to attract the magnetized magnet into the opening groove 151 at the bottom of the transfer plate 14. The first pneumatic push rod 13 can drive the transfer plate 14 to move in the direction of the opening of the opening groove 151 so that the magnet attracted on the transfer plate 14 is separated from the adjacent magnet.

[0027] like Figure 1 As shown, the transfer plate 14 of the magnet assembly transfer device moves to the upper side of the magazine 110 filled with magnets, and the horizontal movement of the transfer base plate 11 aligns the opening slot 151 on the transfer block 15 with the protruding magnet 111 on the top of the magazine 110. Then, the transfer base plate 11 moves downward so that the transfer block 15 moves downward with the transfer plate 14, allowing the magnet to be transferred to enter the opening slot 151. Since the groove 121 of the transfer slide plate 12 is equipped with a magnetic suction plate (iron plate or magnet), the top of the magnet to be transferred can be attracted to the lower surface of the transfer plate 14 by the magnetic suction plate; Figure 1 As shown, the depth of the opening slot 151 in the vertical direction is less than or equal to the thickness of the magnet to be transferred, meaning that only one magnet to be transferred can be inserted into the opening slot 151. That is, only the magnet to be transferred protruding from the top of the magazine 110 enters the opening slot 151, while the other magnets to be transferred remain in the magazine. Because the magnets to be transferred are magnetized, they attract each other. After the magnet to be transferred 111 protruding from the top of the magazine 110 enters the opening slot 151, the transfer plate 14 is driven by the first pneumatic push rod 13 to move towards the opening of the opening slot 151. This causes the magnet in the opening slot 151 to move horizontally with the transfer plate 14, separating the magnet in the opening slot 151 from the other magnets to be transferred in the magazine 110. This reliably separates the magnet to be transferred from the magazine. During the transfer process, the position and attitude of the magnet will not move, and the magnet can be reliably adsorbed in the opening slot at the bottom of the transfer plate without falling off.

[0028] In one embodiment of this application, the magnetic suction plate installed in the groove 121 of the transfer slide plate 12 is an iron plate. The transfer base plate 11, transfer slide plate 12, transfer plate 14, etc., are all made of non-ferromagnetic materials that cannot be attracted by magnets, such as aluminum alloy. The assembly fixture (assembly plate) is also made of iron plate of the same material as the magnetic suction plate. When the magnet is transferred to the assembly fixture (assembly plate) using the magnet assembly transfer device, the transfer base plate 11 is moved so that the opening groove 151 at the bottom of the transfer plate 14 is aligned with the assembly fixture. Then, the transfer slide plate 12 is moved downward so that the bottom of the transfer block 15 on the lower side of the transfer plate 14 is close to the assembly fixture. On the upper surface of the assembly fixture (assembly plate), the magnetic suction plate in the groove 121 of the assembly fixture magnetically attracts the magnet in the opening slot 151. However, because the lower surface of the magnet in the opening slot 151 is in direct contact with the assembly fixture, the upper surface of the magnet in the opening slot 151 is attracted to the lower surface of the transfer plate 14, and the distance between the magnet and the magnetic suction plate in the groove 121 is the thickness of the transfer plate 14. The attraction force of the assembly fixture on the magnet is greater than the attraction force of the magnetic suction plate on the magnet. Thus, the magnet to be transferred in the opening slot 151 is transferred and attracted to the assembly fixture, realizing the reliable transfer of the magnet.

[0029] In one embodiment of this application, preferably, as shown below, Figure 5As shown, a transfer slide rail 122 is also installed on the transfer base plate 11, and a transfer slider 121 adapted to the transfer slide rail 122 is provided on the transfer slide plate 12, so that the transfer slide plate 12 can reliably slide relative to the transfer base plate 11.

[0030] In one embodiment of this application, preferably, as shown below, Figure 6 , Figure 7 As shown, a plurality of transfer blocks 15 are protruding from the bottom surface of the transfer plate 14, and each transfer block 15 is provided with an opening groove 151; the opening direction of each opening groove 151 is the same; thus, multiple magnets can be transferred simultaneously. Preferably, the lower inner edge of the opening groove 151 is also provided with a feeding guide slope, so that the magnet can accurately enter the opening groove 151. The transfer plate 14 at the bottom of the opening groove 151 is also provided with a vent hole to prevent the magnet from being attracted into the opening groove 151 due to negative pressure, which would affect the magnet's detachment during material discharge.

[0031] In one embodiment of this application, preferably, as shown below, Figures 6 to 9 As shown, a downwardly extending limiting plate 16 is also installed at the end of the transfer base plate 11 opposite to the first pneumatic push rod 13. The limiting plate 16 is provided with a limiting hole, and the end of the transfer slide plate 12 is provided with a connecting hole corresponding to the limiting hole. A limiting pin 161 is installed in the connecting hole of the transfer slide plate 12 and passes through the limiting hole. A compression spring is also sleeved on the limiting pin 161 between the limiting plate and the transfer slide plate. The limiting plate 16 makes the transfer slide plate 12 reliably positioned at the left end of the transfer base plate 11, and the compression spring can play a buffering role between the limiting plate 16 and the transfer slide plate 12.

[0032] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the magnet assembly transfer device also includes a mounting vertical plate 21 and a vertical sliding plate 22. The vertical sliding plate 22 is slidably mounted on the mounting vertical plate 21. The mounting vertical plate 21 is also provided with a second pneumatic push rod 23 that drives the vertical sliding plate 22 to slide up and down. The transfer base plate 11 is mounted on the bottom end of the vertical sliding plate 22, thereby driving the transfer base plate 11 to move up and down.

[0033] In one embodiment of this application, preferably, the mounting plate 21 is further provided with a vertical slide rail 211, and the vertical slide plate 22 is provided with a vertical slider 221 adapted to the vertical slide rail 211, so that the vertical slide plate 22 can reliably slide relative to the mounting plate 21.

[0034] In one embodiment of this application, preferably, as shown below, Figure 3 , Figure 8 As shown, a vertical buffer spring 24 is also provided between the mounting plate 21 and the vertical slide plate 22.

[0035] In one embodiment of this application, preferably, as shown below, Figure 1 , Figure 2As shown, the magnet assembly transfer device also includes a base 30, on which a feeding slide plate 31 is slidably mounted. A mounting vertical plate 21 is connected to the feeding slide plate 31 via a connecting horizontal plate 32. A feeding assembly for driving the feeding slide plate 31 to move horizontally on the base 30 is also mounted on the base 30. Preferably, the feeding assembly includes a mounting plate 33, a motor 41, a driving pulley 42, a driven pulley 43, and a belt 44. The motor 41 is mounted on the mounting plate 33, the driving pulley 42 is mounted on the output shaft of the motor 41, and the driven pulley 43 is rotatably mounted on the mounting plate 33. A belt 44 is provided between the driving pulley 42 and the driven pulley 43. The belt 44 is preferably a synchronous belt. The feeding slide plate 31 is fixedly connected to the belt 44, thereby driving the feeding slide plate 31 to move back and forth.
