Description

Technical Field

[0001] The invention relates to the technical field of earphone shell cleaning, and in particular to an earphone shell cleaning device. Background Art

[0002] The headphone shell consists of a hard part and a soft part. The hard part is a frame made of plastic or metal, and the soft part is made of sponge wrapped in flexible material, which is used to fit the human ear. Therefore, the soft part of the headphone shell is also called the headphone cover.

[0003] The existing Chinese public patent CN116689348B discloses a surface wiping and cleaning device for the production of circular earphone covers. The wind force is used to firmly adsorb the earphone cover on the moving block, and then the bristles rotate and wipe and clean the earphone cover passing below, thereby removing small impurities on the surface of the earphone cover and substances adsorbed by static electricity, ensuring the cleanliness of the surface of the earphone cover, thereby ensuring the production quality of the product. When the earphone cover moves between two sets of belts, the flip panel will shovel towards the earphone cover and turn it over. After turning over, the earphone cover will be cleaned by the bristles to avoid dead corners in the wiping of the earphone cover, thereby achieving comprehensive wiping and cleaning of the earphone cover. When the above device flips the headphone cover, the flip panel is inserted between the headphone cover and the moving block, and the moving block continues to move through the two sets of rack plates to drive the second gear to rotate, so that the second gear drives the first gear and the flip panel to rotate. However, during the rotation of the flip panel, the headphone cover will slide along the surface of the flip panel and separate from the flip panel. After the headphone cover slides off the flip panel, it may be in a flipped state or remain in its original state, so that the device cannot control the flipping state of the headphone cover when turning the headphone cover over, and it needs to be improved.

The left end of the screw 2 11 is fixedly connected to a long connecting rod 13, and an electric push rod 14 is fixedly installed at the center of the lower end of the moving plate 9.

[0024] The clamping assembly includes a hollow seat 15 fixedly installed on the lower end of the electric push rod 14, the lower end of the hollow seat 15 is fixedly connected with a pressure plate 16, the lower end of the pressure plate 16 is movably embedded with an embedding rod 17 at the center of the lower end, the lower end of the embedding rod 17 is fixedly connected with a pressure plate 2 18, an annular airbag 19 is movably sleeved on the outer side of the embedding rod 17, and the two ends of the annular airbag 19 are respectively fixedly connected to the pressure plate 16 and the pressure plate 2 18, and the pressure plate 16 and the pressure plate 2 18 are used to squeeze the annular airbag 19.

[0025] The upper end of the embedded rod 17 is fixedly connected to a spline seat 20, and the spline seat 20 can move up and down inside the hollow seat 15, and the spline seat 20 cannot rotate inside the hollow seat 15. A spring 21 is movably abutted against the side of the spline seat 20 away from the embedded rod 17.

A plug-in hole 26 is opened on the side wall of the hollow seat 15, and the pin rod 23 is movably plugged into the hollow seat 15 through the plug-in hole 26.

[0027] Working principle: When cleaning the finished earphone cover 8, the robot places the earphone cover 8 at the center of the upper end of the moving seat 4, and makes the side of the earphone cover 8 with the concave portion face upwards. Since the other side of the earphone cover 8 is relatively flat and has a larger contact surface with the moving seat 4, the moving seat 4 can adsorb the earphone cover 8 through negative pressure. During the process of the screw 6 rotating to drive the moving seat 4 to move to the right, the conveyor belt 2 on the left side conveys multiple cleaning brushes 3, and the cleaning brushes 3 sweep away impurities on the surface of the earphone cover 8 during the movement; When the moving seat 4 drives the earphone cover 8 to move to the center of the chassis 1, the electric push rod 14 is just above the moving seat 4, and then the electric push rod 14 drives the clamping assembly to move downward. In the process of the clamping assembly pressing against the earphone cover 8 and continuing to move, the position of the pressure plate 2 18 remains unchanged, and the pressure plate 1 16 continues to move downward to squeeze the annular airbag 19. After the annular airbag 19 is compressed, the diameter of the outer wall of the annular airbag 19 changes until the outer wall of the annular airbag 19 presses against the inner wall of the earphone cover 8. At the same time, the spline seat 20 in the locking assembly drives the pin rod 23 to move to the plug hole At 26, the pin rod 23 is driven by the V-shaped spring piece 25 to be embedded in the plug-in hole 26 to position the pressure plate 18. At this time, the electric push rod 14 can drive the earphone cover 8 to move upward through the annular airbag 19. In the process of the screw 11 rotating to drive the electric push rod 14 and the earphone cover 8 to move to the right, the multiple cleaning brushes 3 located on the right conveyor belt 2 move to remove impurities on the lower end surface of the earphone cover 8, thereby realizing double-sided cleaning of the earphone cover 8 without turning the earphone cover 8 over, effectively improving the controllability of the cleaning work of the earphone cover 8.

[0028] Example 2: Please refer to Figure 2 , Figure 6-Figure 8 The present embodiment further explains the first embodiment, the unlocking assembly includes a sleeve 27 fixedly mounted on the outside of the hollow seat 15, a push rod 28 is passed through the inside of the sleeve 27, both ends of the push rod 28 are movably embedded with ball 1 29, and a ball 1 29 close to the spline seat 20 is movably abutted against the hemispherical portion of the pin 23, the push rod 28 is used to drive the pin 23 to move out of the plug hole 26, and a gasket 2 30 is fixedly sleeved on the outside of the push rod 28 corresponding to the inside of the sleeve 27.

[0029] A spring 2 31 is movably sleeved on the outer side of the push rod 28, and the two ends of the spring 2 31 are movably abutted against the sleeve 27 and the gasket 2 30 respectively. Two symmetrically distributed baffles 32 are fixedly installed inside the chassis 1, and the two baffles 32 are close to the right end of the chassis 1. The two baffles 32 are close to each other. One end is provided with a bevel portion 33. The push rod 28 is in rolling contact with the baffle 32 through the ball 1 29 and the bevel portion 33. The baffle 32 can drive the push rod 28 to move toward the spline seat 20 through the bevel portion 33.

[0030] In this embodiment: when the electric push rod 14 and the earphone cover 8 move to the baffle 32 and continue to move, the ball 29 at the end of the push rod 28 away from the hollow seat 15 will roll along the bevel portion 33 of the baffle 32, that is, the baffle 32 drives the push rod 28 to move into the sleeve 27 through the bevel portion 33. In the process of moving into the sleeve 27, the push rod 28 is supported by the pin rod 23 through the ball 29 and moves into the sleeve 22. After the pin rod 23 moves a certain distance, the spline seat 20 will move down and reset under the drive of the compression elastic force of the spring 21. In this process, the outer wall diameter of the annular airbag 19 is reduced, and the earphone cover 8 can automatically detach from the clamping assembly and fall into the collection frame, which is convenient for automatic discharging.

[0034] In this embodiment, the plurality of cleaning brushes 3 will contact the plurality of tooth comb rods 36 in the dust removal mechanism during the rotation process, and the impurities attached to the cleaning brushes 3 will be sucked into the conduit 1 34 or the conduit 2 35 through the suction grooves 37 on the tooth comb rods 36, and preferably sent into the gas purifier, which is conducive to removing the dust and impurities attached to the cleaning brushes 3 and can effectively prevent the dust and impurities from accumulating inside the cleaning brushes 3; During the cleaning process of the earphone cover 8, when the triangular top block 42 moves to the bending connecting rod 39 with the movable seat 4, the triangular top block 42 drives the bending connecting rod 39, the conduit 1 34 and the multiple suction tubes 43 to move downward through the ball 2 41. When the earphone cover 8 moves to directly below the multiple suction tubes 43, the triangular top block 42 drives the suction tubes 43 to move downward to the lowest point through the bending connecting rod 39, so that the multiple suction tubes 43 are located in the recessed portion of the earphone cover 8, which is conducive to the suction tubes 43 to absorb impurities in the recessed portion of the earphone cover 8, and can further improve the cleaning effect of the earphone cover 8.
