[0002] Vibrating feeders are common feeding devices. They can efficiently and stably feed materials that are regularly shaped, of average size, and do not require error-proofing in either direction. However, for irregularly shaped, miniature materials that require error-proofing in either direction, ordinary vibrating feeders, due to their simple structure and limited functionality, cannot achieve orderly feeding. They require a sorting mechanism at the rear end, which is costly and complex. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1-7 As shown, embodiments of the present invention include:

[0023] A miniature automatic material feeding device includes a platform 1, a hopper 2, a side baffle 3, a storage pipe 4, a notch 5, a recycling box 7, a pneumatic pusher block, a compressed air nozzle 9, a vertical vibrator 10, and a cutting device 11. The hopper 2 is vertically arranged on the platform 1. The side baffle 3 is longitudinally arranged along the outer edge of the hopper 2. Several storage pipes 4, which are matched and limited by the side baffle 3, are stacked and stored in the hopper 2. The side baffle 3 has a notch 5 at its lower end to form an outlet. The storage pipes 4 are stacked to form a material wall 402. The recycling box 7 is arranged at the front of the material wall 402 with equal length. The pneumatic pusher block with a positive inlet outlet is arranged at the rear of the material wall 402. The two ends of the storage pipe 4 that is inlet are respectively connected to the compressed air nozzle 9 and the vertical vibrator 10. The cutting device 11 is connected to the lower part of the vertical vibrator 10.

[0024] The hopper 2 is composed of a pair of upright square grooves 201, and the spacing between the square grooves 201 corresponds to the length of the storage pipe 4.

[0025] Furthermore, a plurality of anti-rotation baffles 401 are provided inside the storage pipe 4 along the pipe diameter direction, and the anti-rotation baffles 401 form a gas pressurization channel with a comb-shaped cavity structure.

[0026] Furthermore, the material wall 402 is constructed by stacking storage pipes 4 in a single-row, single-pipe structure.

[0027] Furthermore, the pneumatic push block consists of a cylinder 801 and a push rod 802. The cylinder 801 is vertically connected to the push rod 802. The height of the push rod 802 is lower than the thickness of the storage tube 4, and the push rod 802 is parallel to the storage tube 4.

[0028] Furthermore, a vertical through hole 202 is provided at the lower part of the square channel 201 corresponding to the position of the second layer storage pipe 4 in the hopper 2. A slide rail 203 is vertically provided on the outer wall of the square channel 201, and a pneumatic bearing seat 204 is provided on the slide rail 203. The pneumatic bearing seat 204 is connected to an L-arm 205. A driven pulley is provided in the middle of the L-arm 205. A directional track 206 is provided on the outer wall of the square channel 201, and the driven pulley is fitted in the directional track 206. A damping block 207 is integrated at the lower end of the L-arm 205 and faces the vertical through hole 202. Driven by the pneumatic bearing seat 204, the L-arm 205 swings along the directional track 206 and passes through the vertical through hole 202 at appropriate times to extend into the opening of the storage pipe 4, thereby connecting and lifting the second layer storage pipe 4 in the hopper 2.

[0029] Furthermore, a detection photoelectric sensor 1111 is embedded in the lower part of the square groove 201 at the position corresponding to the first layer of the storage pipe 4 of the hopper 2, facing the inner cavity of the storage pipe 4.

[0030] Furthermore, the cutting device 11 consists of a cutting table 1101, a fine-tuning slide, a single-piece cavity 1102, a material shortage detection photoelectric sensor 1112, and a mistake-proof detection photoelectric sensor 1113. The cutting table 1101 is provided with a fine-tuning slide, and the surface edge of the fine-tuning slide is provided with a single-piece cavity 1102. The single-piece cavity 1102 is connected to the direct vibrator 10. The outer periphery of the single-piece cavity 1102 is provided with a material shortage detection photoelectric sensor 1112 and a mistake-proof detection photoelectric sensor 1113.

[0031] like Figure 3 As shown, the storage tube 4 is filled with a large number of miniature Hall sensor components. Due to the irregular shape and miniature size of these components, feeding them with a regular vibratory feeder will result in skewed orientation. To solve the feeding problem of these miniature components, a specially designed storage tube 4 is used for preliminary sorting. The sorted individual storage tubes 4 are then stacked and stored in the hopper 2. During production, the equipment pushes the storage tubes 4 out of the hopper 2 one by one. The opening of the storage tube 4 in the hopper 2 is matched with a compressed air nozzle 9. Since the storage tube 4 is hollow, it naturally forms a unidirectional compressed air flow channel. When the compressed air nozzle 9 injects compressed air into the tube, the compressed air can push the miniature components out from the other end of the storage tube 4. The pushed-out components enter the vertical vibrator 10 and are then sent to the cutting device 11 for shaping.

[0032] In order to prevent the miniature parts inside the storage tube 4 from being disturbed by the compressed air and the air cyclone, a baffle is added inside the storage tube 4. This not only suppresses the spinning of the parts, but also helps to regulate the air pressure and direction in the flow channel, thereby improving the stability of the tube.

[0033] The material cutting device 11 has an external orientation sensor installed in the material cavity, which can detect whether the material is stuck or whether the material is placed in the correct orientation, thus preventing mistaken identification.

[0034] like Figure 5 , 6 As shown, the storage pipe 4 at the bottom of the hopper 2 in the first layer will be pushed out, and the storage pipe 4 in the second layer will be hooked and lifted by the L-arm 205, which can reduce the damping of the pushing process.

[0035] In summary, the present invention provides an automatic feeding device for micro-components, which feeds micro-components in batches by pushing them out horizontally through a stacked hopper 2, and uses a storage tube 4 with cyclone suppression function to stack and store micro-components. The components in the storage tube 4 are fed into the direct vibrator 10 by compressed air drive, which solves the problem of orderly feeding of micro-components and improves feeding efficiency and stability.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
