[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, an embodiment of the present application provides a vibrating feeder, including a base 1 , on which a tray 3 and two vibrating components 2 are provided. The two vibrating components 2 are symmetrically mounted on the base 1 , and the tray 3 is mounted on the two vibrating components 2 .

[0020] like Figure 2 As shown, the vibration assembly 2 includes a voice coil motor 21, an elastic assembly 22 and a connecting plate 23. The driving end of the voice coil motor 21 is connected to the connecting plate 23. The elastic assembly 22 is sleeved on the voice coil motor 21. One end of the elastic assembly 22 is connected to the bottom of the voice coil motor 21, and the other end of the elastic assembly 22 is connected to the bottom of the connecting plate 23. The two ends of the bottom of the tray 3 are respectively connected to the top of the connecting plates 23 of the two vibration assemblies 2.

[0021] Specifically, the elastic component 22 is mounted on the voice coil motor 21. The stator 211 of the voice coil motor 21 is connected to the base 1, and the mover 212 is connected to the connecting plate 23. One end of the elastic component 22 is connected to the bottom of the stator 211, and the other end of the elastic component 22 is connected to the connecting plate 23. The elastic component 22 supports the mover 212 and the connecting plate 23, so that the mover 212 and the connecting plate 23 are located at the middle equilibrium point. The tray 3 is mounted on the connecting plates 23 of the two voice coil motors 21. The voice coil motors 21 drive the mover 212 to move the tray 3 up and down, and the tray 3 vibrates up and down to feed the product.

[0022] In the above structure, the voice coil motor 21, the elastic component 22 and the tray 3 cooperate with each other to realize the sequential and orderly feeding of products. The vibration feeder is not only simple in structure, easy to operate and takes up little space, but also improves feeding efficiency and reduces operating noise.

[0023] like Figure 2 As shown in one embodiment, the voice coil motor 21 of the vibrating feeder includes a stator 211, a mover 212, and a coil 213. The stator 211 is mounted on the base 1. The elastic component 22 is sleeved on the stator 211 and connected to the bottom of the stator 211. The inner wall of the stator 211 is circumferentially provided with a permanent magnet 214. The coil 213 is wound around the mover 212. The end of the mover 212 away from the coil 213 is connected to the connecting plate 23. The stator 211 is provided with a through hole for the mover 212 and the coil 213 to slide. The coil 213 and the permanent magnet 214 do not contact each other. When current passes through the coil 213, the coil 213 generates a magnetic field. This magnetic field interacts with the magnetic fields generated by the two permanent magnets 214, causing the coil 213 to drive the mover 212 in an upward and downward linear motion. The configuration of the voice coil motor 211 achieves high-frequency vibration of the tray 3, improving product feeding efficiency and reducing noise.

[0024] like Figure 2 As shown in one embodiment, the stator 211 and the mover 212 of the vibration feeder are both cylindrical structures. The voice coil motor 21 of this structure is compact and occupies a small area.

[0025] like Figure 2 As shown, in one embodiment, the elastic component 22 of the vibration feeder is a spring. The setting of the spring not only provides support for the mover 212 and the connecting plate 23, but also improves the vibration efficiency of the equipment.

[0026] like Figure 1 As shown, in one embodiment, the tray 3 of the vibration feeder is provided with a plurality of troughs for the products to pass through in sequence. This arrangement facilitates the orderly and sequential feeding of the products.

[0027] like Figure 1 As shown, in one embodiment, the base 1 and tray 3 of the vibrating feeder are rectangular structures. This arrangement facilitates improving the stability of equipment operation and feeding.

[0028] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
