Description

Technical Field

[0001] This utility model relates to magnet assembly technology, and in particular to a lifting and feeding 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 process of assembling magnets, each magnet block needs to be placed into the assembly fixture according to the requirements. The existing magnet block feeding device cannot feed from bottom to top, which limits the structural design and module layout of the magnet assembly equipment. Utility Model Content

[0004] The purpose of this invention is to provide a lifting and feeding device for magnet assembly, which solves the problem that existing magnet feeding devices for magnet assembly cannot feed materials from bottom to top.

[0005] To address the aforementioned problems, this utility model provides a lifting and feeding device for magnet assembly, comprising a base plate and a magazine. The magazine is mounted on the base plate and contains elongated magnets. The magazine has a magnet receiving groove arranged vertically, and multiple magnets are filled in the magnet receiving groove. The magnets can slide upward within the magnet receiving groove. The magazine also has a lifting slide groove corresponding to the magnet receiving groove, with an opening at the lower side. A lifting plate is also mounted on the base plate, and the lifting plate has a pusher plate that can be inserted into the lifting slide groove through the lower opening. When the lifting plate moves upward, the pusher plate pushes the magnets in the magnet receiving groove upward.

[0006] The lifting and feeding device for magnet assembly provided by this utility model also has the following technical features: Furthermore, the lifting plate is provided with mounting holes, and the pusher plate is provided with guide vertical holes corresponding to the mounting holes. The pusher plate is connected to the lifting plate through a positioning pin passing through the guide vertical hole. A buffer spring is also installed between the pusher plate and the lifting plate to make the pusher plate and the lifting plate elastically connected.

[0007] Furthermore, the magazine is provided with two or more magnet receiving slots arranged in the front-back direction, and the pusher plate passes through the lifting slide along the front-back direction of the magazine and can simultaneously push the magnets in the magnet receiving slots arranged in the front-back direction upward.

[0008] Furthermore, the magazine is provided with a plurality of magnet receiving slots arranged in the left-right direction, and the lifting plate is equipped with a plurality of pusher plates arranged in the left-right direction.

[0009] Furthermore, the lifting plate is also provided with a vertical through hole that is adapted to the bottom of the magazine.

[0010] Furthermore, a magazine fixing plate is installed on the upper side of the base plate, and the top of the magazine is connected to the magazine fixing plate.

[0011] Furthermore, a lifting assembly for driving the lifting plate to move up and down is also installed on the base plate.

[0012] Furthermore, the lifting assembly shown is installed on the underside of the base plate, and a lifting horizontal plate is installed on the lifting slider of the lifting assembly. The lifting horizontal plate is connected and fixed to the lifting plate through two lifting vertical plates. The base plate is provided with through holes corresponding to the lifting vertical plates, and the lifting vertical plates pass through the through holes and are connected to the lifting plate at their upper ends.

[0013] Furthermore, a guide plate corresponding to the lifting plate is also installed on the base plate, a slide rail is installed on the guide plate, and a slider adapted to the slide rail is installed on the lifting plate.

[0014] The present invention has the following advantages: By ingeniously setting a lifting groove with a lower opening on the lower side of the magazine, and setting a pusher plate that can be inserted into the lifting groove on the lifting plate, the magnets in the magazine can be pushed upward in a reliable and stable manner to supply materials for magnet assembly.

Detailed Implementation

[0016] 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.

[0017] like Figures 1 to 10 In the embodiment of the magnet assembly lifting and feeding device of this utility model shown, the magnet assembly lifting and feeding device includes a base plate 10 and a spring clip 20. The spring clip 20 is mounted on the base plate 10 and is filled with elongated magnets 201. The spring clip 20 is provided with a magnet receiving groove 21 arranged vertically. The magnet receiving groove 21 is filled with a plurality of magnets 201. Specifically, the plurality of magnets 201 are stacked sequentially in the magnet receiving groove 21 and can slide upward in the magnet receiving groove 21. The spring clip 20 is also provided with a part arranged along the front-back direction of the spring clip 20 and opposite to the magnet receiving groove 21. The corresponding lifting chute 22 has a lower opening, and a lifting plate 30 is also installed on the base plate 10. The lifting plate 30 is provided with a pusher plate 31 that can be inserted into the lifting chute 22 through the lower opening. When the lifting plate 30 moves upward, the pusher plate 31 pushes the magnet 201 in the magnet receiving groove 21 upward. This application, by cleverly setting a lifting chute 22 with a lower opening on the lower side of the magazine and setting a pusher plate 31 that can be inserted into the lifting chute 22 on the lifting plate 30, can reliably and stably push the magnet 201 in the magazine 20 upward in sequence, thus supplying materials for magnet assembly.

[0018] In one embodiment of this application, preferably, as shown below, Figure 9 , Figure 10 As shown, the lifting plate 30 is provided with mounting holes 301, and the pusher plate 31 is provided with guide vertical holes corresponding to the mounting holes 301. The pusher plate 31 is connected to the lifting plate 30 through a positioning pin 311 passing through the guide vertical hole. A buffer spring 312 is also installed between the pusher plate 31 and the lifting plate 30 to make the pusher plate 31 and the lifting plate 30 elastically connected. Figure 10As shown, the buffer spring 312 is a compression spring. The lower side of the pusher plate 31 and the upper side of the lifting plate 30 are respectively provided with spring mounting holes. The buffer spring 312 is installed in the spring mounting holes. When the upper surface of the pusher plate 31 does not contact the magnet 201 in the magnet receiving groove 21, the upper surface of the pusher plate 31 contacts the pin of the positioning pin 311 under the action of the buffer spring 312. When the upper surface of the pusher plate 31 contacts the magnet 201 in the magnet receiving groove 21, the buffer spring 312 can be compressed. This elastic connection structure of the pusher plate 31 can prevent the pusher plate 31 from excessively squeezing the magnet 201 and causing the magnet to break.

[0019] In one embodiment of this application, preferably, as shown below, Figures 4 to 6 As shown, the magazine 20 is provided with two or more magnet receiving slots 21 arranged in the front-to-back direction, such as... Figure 1 As shown, the pusher plate 31 is inserted into the lifting slide groove 22 along the front-back direction of the magazine 20, and can simultaneously push the magnets in the magnet receiving groove 21 arranged along the front-back direction upward. Thus, one pusher plate 31 can simultaneously push the magnets 201 in the magnet receiving groove 21 arranged along the front-back direction of the magazine 20 upward.

[0020] In one embodiment of this application, preferably, as shown below, Figures 4 to 6 As shown, the magazine 20 is provided with multiple sets of magnet receiving slots 21 arranged in the left and right directions. Each set of magnet receiving slots 21 is provided with a lifting slide 22. The lifting plate 30 is equipped with multiple push plates 31 arranged in the left and right directions. Each push plate 31 is provided with a lifting slide 22. Thus, when the lifting plate 31 moves upward, it can push the magnets in the multiple sets of magnet receiving slots 21 upward at the same time.

[0021] In one embodiment of this application, preferably, as shown below, Figures 4 to 6 As shown, the magazine 20 includes a magazine base plate 23 located in the middle, and magazine cover plates 24 located on the front and rear sides of the magazine base plate 23. Magnet receiving slots 21 are opened on the front and rear sides of the magazine base plate 23 to facilitate magazine manufacturing and assembly.

[0022] In one embodiment of this application, preferably, as shown below, Figures 7 to 9 As shown, the lifting plate 30 is also provided with a vertical through hole 302 that is adapted to the bottom of the magazine 20, so that the lifting plate 30 can reliably move upward relative to the magazine 20.

[0023] In one embodiment of this application, preferably, as shown below, Figure 1 As shown, a magazine fixing plate 11 is installed on the upper side of the base plate 10, and the top of the magazine 20 is connected to the magazine fixing plate 11.

[0024] In one embodiment of this application, preferably, as shown below, Figures 1 to 3 , Figure 7 , Figure 8As shown, a lifting assembly 40 for driving the lifting plate 30 to move up and down is also installed on the base plate; specifically, the lifting assembly 40 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 40 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.

[0025] In one embodiment of this application, preferably, as shown below, Figures 1 to 3 , Figure 7 , Figure 8 As shown, the lifting assembly 40 is hidden on the lower side of the base plate 10, and the magazine 20 is installed on the upper side of the base plate 10, making the equipment layout reasonable and the appearance simple. The lifting slider of the lifting assembly 40 is equipped with a lifting horizontal plate 41. The lifting horizontal plate 41 is connected and fixed to the lifting plate 30 through two lifting vertical plates 42. The base plate 10 is provided with through holes corresponding to the lifting vertical plates 42. The lifting vertical plates 42 are inserted into the through holes and their upper ends are connected to the lifting plate 30, so that the lifting assembly 40 can drive the lifting plate 30 to move up and down.

[0026] In one embodiment of this application, preferably, as shown below, Figures 1 to 3 , Figure 7 , Figure 8 As shown, a guide plate 12 corresponding to the lifting plate 42 is also installed on the base plate 10. A slide rail is installed on the guide plate 12, and a slider adapted to the slide rail is installed on the lifting plate 42, so that the lifting plate 30 can move up and down reliably.

[0027] 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.
