In the production and processing of electronic products, diaphragms (microphone, headphone, speaker, etc.), and electroacoustic equipment, some equipment requires magnets that are not conventionally rectangular or circular shapes. Depending on the product processing requirements, magnets need to be assembled into a shape and size suitable for the specific equipment.

[0003] For example, the magnetic ring assembly disclosed in the Chinese utility model patent document "CN202222384665.X A magnetic component and a magnetic ring assembly having the magnetic component" has multiple fan-shaped magnetic blocks arranged in a ring structure. When assembling such a ring-shaped combined magnet, multiple fan-shaped magnetic blocks need to be placed on the assembly table according to the preset position. The manual operation is inefficient and the positioning accuracy of the magnetic blocks is poor. Since the fan-shaped magnetic blocks are small in size, the magnetic blocks are easy to fall off during the placement process when using a robotic arm. The robotic arm occupies a lot of space and has a high cost. Utility Model Content

[0018] 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.

[0019] like Figures 1 to 4 In the embodiment of the magnet assembly feeding mechanism of this utility model shown, the magnet assembly feeding mechanism includes a support 10 and a feeding box 20. The feeding box 20 is fixed on the upper side of the support 10. A feeding head 21 extending out of the feeding box 20 is installed inside the feeding box 20. A suction nozzle 201 capable of adsorbing / releasing magnetic blocks is installed on the feeding head 20. A drive mechanism for driving the feeding head 21 to reciprocate between the suction station and the discharge station is installed inside the feeding box 20. The drive mechanism includes a slider mounting plate 22 and a swing arm 23 connected to the motor output shaft. A horizontal slide rail 24 is provided inside the feeding box 20. A horizontal slider 221 adapted to the horizontal slide rail 24 is provided on the slider mounting plate 22. Plate 22 can slide horizontally within the feeding box 20 along the horizontal slide rail 24; a vertical slider 222 that moves with the slider mounting plate 22 is also installed on the slider mounting plate 22; a vertical slide rail 25 that passes through the vertical slider 222 is also installed inside the feeding box 20; a vertical connecting plate 26 is fixed to the upper end of the vertical slide rail 25; the feeding head 21 is fixed on the vertical slide rail 25 and moves with the vertical slide rail 25; a lever 261 is installed on the vertical connecting plate 26; a socket 231 is provided on the swing arm 23; the lever 261 passes through the socket 231; when the motor 27 drives the swing arm 23 to swing, the swing arm 23 drives the vertical slide rail 25 to move within the feeding box 20 through the lever 261 and the vertical connecting plate 26.

[0020] Specifically, in the above embodiment, the insertion hole 231 can be a circular hole, the outer diameter of the lever 261 is adapted to the inner diameter of the insertion hole 231, and the movement trajectory of the lever 261 under the action of the swing arm 23 is an arc; inside the loading box 20, the slider mounting plate 22 can only slide horizontally along the horizontal slide rail 24 within the loading box 20, the vertical slider 222 can only slide horizontally with the slider mounting plate 22 within the loading box 20, and the vertical slide rail 25 can move horizontally with the slider mounting plate 22 and can move up and down relative to the slider mounting plate 22. Under the drive of the lever 261 and the vertical connecting plate 26, the movement trajectory of the vertical slide rail 25 within the loading box 20 is an arc. The feed head 21 is fixed on the vertical slide rail 25 and moves with the vertical slide rail 25. The suction nozzle 201 is installed on the feed head 21, so that the movement trajectory of the suction nozzle 201 is synchronized with the movement trajectory of the lever 261, so that the suction nozzle 201 can reliably move back and forth between the suction station and the discharge station according to the preset trajectory, and transfer the fan-shaped magnetic block from the suction station to the discharge station for release. The feed mechanism for the above-mentioned magnet assembly in this application has a drive mechanism whose size can be designed as needed, has a compact structure, and occupies little space. Each component can be made or purchased as needed. The slider, guide rail, motor and other components have high versatility, are easy to purchase, and have low cost.

[0021] like Figure 1 The diagram shown is a schematic of the use of the magnet assembly feeding mechanism of this application. The worktable 100 is provided with a magnet assembly disc 110 and a vibrating feeding disc 120. The magnet assembly feeding mechanism of this application is used to transfer the magnetic blocks at the outlet of the vibrating feeding disc 120 to the magnet assembly disc 110.

[0022] In one embodiment of this application, preferably, the upper end of the suction nozzle 201 is also connected to a vent tube that moves with the suction nozzle 201, and the suction nozzle 201 uses the principle of negative pressure adsorption to adsorb the magnetic block.

[0023] In one embodiment of this application, preferably, the feeding head 21 includes a vertical connecting plate 211 and a horizontal bar 212. The vertical connecting plate 211 is fixedly connected to the vertical slide rail 25. A suction nozzle 201 is installed at one end of the horizontal bar 212 that extends out of the feeding box 20. The side wall of the feeding box 20 is also provided with a notch for the horizontal bar 212 to move up and down, so that most of the structure of the feeding head 21 is hidden inside the feeding box, making the feeding mechanism for magnet assembly compact and the box can also protect the internal structure.

[0024] In one embodiment of this application, preferably, the insertion hole 231 is an elongated hole, the width of which is equal to the outer diameter of the lever 261; a guide plate 28 is also fixed inside the loading box 20, the guide plate 28 is provided with a guide groove 281 corresponding to the lever 261, the width of which is equal to the outer diameter of the lever 261; the lever 261 passes through the insertion hole 231 on the swing arm 23 and extends into the guide groove 281; when the motor 27 drives the swing arm 23 to swing, the vertical connecting plate 26 moves along the trajectory defined by the guide groove 281 within the loading box 20 with the lever 261; specifically In other words, by setting the insertion hole 231 as an elongated hole, when the swing arm 23 swings, the lever 261 can slide relative to the swing arm 23 within the insertion hole 231. The swing arm 23 can drive the lever 261 to move within the guide groove 281. That is, the guide groove 281 limits the movement trajectory of the lever 261, so that the suction nozzle 201 moves synchronously with the movement trajectory of the lever 261. The movement trajectory of the suction nozzle 201 can be limited by the guide groove 281, that is, the movement trajectory of the suction nozzle 201 is controllable. This allows the suction nozzle to reliably reciprocate between the suction station and the discharge station according to a preset trajectory.

[0025] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the guide groove 281 includes two vertical guide grooves and one horizontal guide groove. The upper ends of the two vertical guide grooves are respectively connected to the two ends of the horizontal guide groove, and the connection is provided with a transition fillet. The lever 261 can rise and fall within the two vertical guide grooves and move horizontally back and forth within the horizontal guide groove, so that the movement path of the suction nozzle is: vertical rise after suction -- horizontal movement -- vertical fall -- discharge -- vertical rise after discharge -- horizontal movement -- vertical fall; in addition, as Figure 3 The drive mechanism shown uses motor 27 as a power component to drive swing arm 23 to swing. The rotation speed of swing arm 23 remains constant during the swing. The guide groove 281 in this application allows the lever 261 to move slowly in the two guide grooves. In particular, the suction nozzle 201 moves slowly when it is close to the suction station and the discharge station, which can effectively reduce the impact caused by excessive speed and prevent the magnetic block adsorbed by the suction nozzle 201 from falling off accidentally.

[0026] In one embodiment of this application, preferably, the top of the vertical connecting plate 26 is also provided with a horizontal positioning piece 262, and a plurality of position detection sensors 263 corresponding to the horizontal positioning piece 262 are installed in the feeding box 20 to detect the position of the vertical connecting plate 26, so as to ensure that the suction nozzle 201 moves reliably under the action of the driving mechanism.

[0027] In one embodiment of this application, preferably, the motor 27 is installed outside the loading box 20, and a reducer 271 is also connected to the output shaft of the motor 27. The output shaft of the reducer 271 extends into the loading box 20 and is fixedly connected to the swing arm 23, so that the loading mechanism for magnet assembly has a compact structure.

[0028] 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.
