[0003] Chinese utility model patent application number CN201821440887.6 discloses an electromagnetic flexible material selector, comprising a connecting plate, a storage bin, and a feed chute. The feed chute is located at the lower end of the storage bin. A first spring leaf is provided at the upper end of the connecting plate, the upper end of which is fixedly connected to a rotating conveyor platform. The lower end of the rotating conveyor platform is connected to the first electromagnet via a first electromagnetic armature.

[0036] See also Figure 1 、 Figure 2This embodiment provides a single voice coil motor automatic feeding bin, comprising a feeding bin 1, a base plate 2, and a feeding drive mechanism disposed between the feeding bin 1 and the base plate 2. The feeding drive mechanism comprises a voice coil motor 3, a first elastic component 4, and a second elastic component 5. The mover of the voice coil motor 3 and the first elastic component 4 are disposed at the bottom rear end of the feeding bin 1, and the first elastic component 4 is sleeved on the outside of the first voice coil motor 3. The second elastic component 5 is disposed at the bottom front end of the feeding bin 1. The stator of the voice coil motor 3, the upper end of the first elastic component 4, and the upper end of the second elastic component 5 are all fixed to the bottom of the feeding bin 1. The lower end of the voice coil motor 3, the lower end of the first elastic component 4, and the lower end of the second elastic component 5 are all fixed to the top of the base plate 2. In addition, a material stop assembly 6 for controlling the feeding speed is provided at the front discharge port of the feeding bin 1.

[0037] This embodiment adopts a voice coil motor 3 as the feeding drive source of the feeding bin 1, which can accurately control the conveying speed and direction of the material, ensure that the material is smoothly and continuously conveyed forward to the next process, and improve the feeding efficiency and stability. At the same time, combined with the first elastic component 4 and the second elastic component 5, the equipment has higher flexibility in the feeding process and can better adapt to different material characteristics and feeding requirements; the structure is simple, fewer parts are required, which reduces the manufacturing cost, simplifies the maintenance and servicing process, and further reduces the overall operating cost; at the same time, when material accumulates or gets stuck at the discharge port and no material is output for a long time, the voice coil motor 3 can automatically increase the up and down jumping amplitude according to the material jamming feedback signal of the next process, drive the material at the discharge port to jump and convey forward and vibrate the accumulated material, thereby effectively solving the problem of material jamming that is easy to occur at the discharge baffle of the traditional feeder and improves the reliability and automation level of the equipment.

[0038] See also Figure 1 、 Figure 2 In one embodiment, the baffle assembly 6 includes a fixed plate 61, a baffle plate 62, and an adjusting screw 63. The ends of the fixed plate 61 are respectively fixed to the upper ends of the two side plates of the feed bin 1, and the baffle plate 62 is locked to the fixed plate 61 by the adjusting screw 63. Specifically, the fixed plate 61 is provided with a screw hole 611 that cooperates with the adjusting screw 63, and the baffle plate 62 is provided with an elongated hole 621 for the adjusting screw 63 to slide up and down. The adjusting screw 63 passes through the elongated hole 621 and is threadedly connected to the screw hole 611 to lock the baffle plate 62 to the fixed plate 61. By adjusting the position of the adjusting screw 63 in the elongated hole 621 on the baffle plate 62, the gap between the baffle plate 62 and the discharge port of the feed bin 1 can be flexibly adjusted, thereby achieving effective control of the feeding speed. When it is necessary to adjust the feeding speed or replace the baffle plate 62, it is only necessary to loosen the adjusting screw 63, adjust the position of the baffle plate 62 and then re-tighten it. There is no need for complicated disassembly and reassembly processes, which reduces the difficulty and cost of maintenance and adjustment.

[0039] See also Figures 3 to 5 In one embodiment, the voice coil motor 3 includes a mover bracket 31 and a stator bracket 32, which are arranged in an upper and lower position relative to each other. The mover bracket 31 is fixed to the bottom of the feed bin 1, while the stator bracket 32 is fixed to the top of the base plate 2. A magnetic sleeve 33 and a magnetic assembly 34 are provided at the bottom of the mover bracket 31. The magnetic assembly 34 is disposed within the magnetic sleeve 33. A coil bobbin 35 is provided at the top of the stator bracket 32. A coil winding 36 is disposed around the coil bobbin 35. The coil bobbin 35 is vertically movable between the magnetic sleeve 33 and the magnetic assembly 34. A first elastic component 4 is disposed between the mover bracket 31 and the stator bracket 32, and is mounted outside the magnetic sleeve 33 and the coil bobbin 35. By adjusting the current and voltage of the coil winding 36, the output force and vibration amplitude of the voice coil motor 3 can be flexibly controlled, allowing the feed bin 1 to adapt to different types and properties of materials and different production requirements.

[0040] Of course, in another embodiment, a coil skeleton 35 may also be provided at the bottom of the mover bracket 31, and a coil winding 36 may be provided on the outer sleeve of the coil skeleton 35. A magnetic steel sleeve 33 and a magnetic steel assembly 34 may also be provided on the top of the stator bracket 32. The magnetic steel assembly 34 is arranged inside the magnetic steel sleeve 33, and the coil skeleton 35 can be movably arranged between the magnetic steel sleeve 33 and the magnetic steel assembly 34 in the vertical direction.

[0041] See also Figures 3 to 5 In one embodiment, the mover support 31 is provided with a plurality of first heat dissipation holes 311 communicating with the magnetic sleeve 33, and the stator support 32 is provided with a plurality of second heat dissipation holes 321 communicating with the coil bobbin 35. The provision of the plurality of first heat dissipation holes 311 communicating with the magnetic sleeve 33 on the mover support 31 effectively dissipates heat generated by the coil windings 36 within the voice coil motor 3, preventing heat accumulation within the magnetic sleeve 33 and thereby reducing the operating temperature of the motor. This effective heat dissipation reduces the thermal impact on the first elastic component 4 and prevents the attenuation of the first elastic component 4's spring force due to prolonged high-load operation, thereby maintaining the stability and longevity of the motor. Furthermore, because the second heat dissipation holes 321 communicate with the coil bobbin 35, heat generated by the coil windings 36 can be dissipated not only through the first heat dissipation holes 311 to the external environment but also from within the coil bobbin 35 through the second heat dissipation holes 321. This increases the surface area for heat dissipation and accelerates heat dissipation.

[0042] See also Figures 3 to 5In one embodiment, a first heat dissipation groove 312 is provided on the top of the mover bracket 31, one end of the first heat dissipation groove 312 extends to a certain edge of the mover bracket 31, and a first heat dissipation hole 311 is provided at the bottom of the first heat dissipation groove 312. The above-mentioned first heat dissipation groove 312 effectively avoids the problem that the feed bin 1 may block the first heat dissipation hole 311 when the mover bracket 31 is connected to the feed bin 1, ensures that the first heat dissipation hole 311 is unobstructed, and ensures that the heat dissipation effect is not affected. If the top of the mover bracket 31 fits the feed bin 1, the heat inside the magnetic steel sleeve 33 can be conducted along the groove of the first heat dissipation groove 312 after passing through the first heat dissipation hole 311, and dissipated to the external environment at the end of the groove.

[0043] In one embodiment, the material of the magnetic steel sleeve 33 is copper / aluminum / steel, wherein the magnetic steel sleeve 33 made of copper has the best heat dissipation effect, and the magnetic steel sleeve 33 made of aluminum is second.

[0044] See also Figure 6 、 Figure 7 In another embodiment, the first elastic component 4 can be set on the outside of the voice coil motor 3, such as the front side or the rear side, etc., in addition to being set on the outside of the voice coil motor 3. The present invention does not limit this.

[0045] In another embodiment, the voice coil motor 3 includes a mover bracket 31 and a stator bracket 32, which are arranged in an upper and lower relationship. The mover bracket 31 is fixed to the bottom of the feed bin 1, and the stator bracket 32 is fixed to the top of the base plate 2. A magnetic steel assembly 34 is disposed at the bottom of the mover bracket 31, and a coil bobbin 35 is disposed at the top of the stator bracket 32. The coil bobbin 35 is sheathed with a coil winding 36. The coil bobbin 35 is vertically movable around the outside of the magnetic steel assembly 34. The first elastic component 4 is disposed between the mover bracket 31 and the stator bracket 32 and sheathed around the coil bobbin 35. In this embodiment, by eliminating the steel sheathing around the coil winding 36, heat generated by the coil winding 36 can be dissipated promptly, preventing heat accumulation within the steel sheath, thereby reducing the operating temperature of the motor. This effective internal heat dissipation reduces the thermal impact on the first elastic component 4, preventing thermal attenuation of the first elastic component 4's spring force due to prolonged high-load operation, thereby maintaining the stability and longevity of the motor.

[0046] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.

[0047] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
