[0026] Example 2

[0027] like Figure 1-Figure 3 As shown, a device for automatically putting wound battery cells into a box includes all the contents of Example 1. In addition, the dust removal device includes a side plate 11, and the side plate 11 is fixedly installed on one side of the side plate 12 away from the side of the end of the inclined plate 16 that is inclined downward. A partition 22 is fixedly installed between the side plates 11 on both sides, and the partition 22 is arranged in the middle of the upper end of the side plate 11. The dust removal device includes a rotating shaft 25, and the rotating shaft 25 is arranged on the side of the partition 22 close to the inclined plate 16. The rotating shaft 25 is rotatably installed between the side plates 11 on both sides. A motor 24 is fixedly installed on the outer side of the side plate 11. The rotating shaft One end of the rotating shaft 25 passes through the side plate 11 and is fixedly connected to the output end of the motor 24. The dust removal device includes a connecting rod 26, which is fixedly mounted on the two ends of the outer wall of the rotating shaft 25. A feeding trough 27 is provided at one end away from the rotating shaft 25 between the connecting rods 26 at both ends of the rotating shaft 25. The feeding trough 27 is rotatably connected to the connecting rods 26 at both ends. The dust removal device includes a loading plate 21, which is fixedly mounted between the side plates 11 on both sides. The loading plate 21 is arranged at the upper end of the side of the side plate 11 away from the inclined plate 16, and the loading plate 21 is arranged directly below the battery cell 33 wound on the winding machine 32.

[0028] In the above embodiment, it should be noted that the feed trough 27 is a cylindrical structure with an opening on the top surface. The feed trough 27 can accommodate one battery cell 33. The side of the inclined plate 16 close to the partition 22 protrudes slightly. In the initial state, the motor 24 drives the shaft 25 to drive the connecting rod 26 to swing, so that the feed trough 27 stays between the loading plate 21 and the partition 22. After the winding machine 32 automatically disengages the battery cell 33, the battery cell 33 falls to the loading plate 21 and slides into the feed trough 27. By starting the motor 24 again, the shaft 25 drives the connecting rod 26 to swing, so that the feed trough 27 rotates from the lower side of the partition 22 to the side of the inclined plate 16 close to the partition 22. The slightly protruding end of the inclined plate 16 blocks the outer edge of one side of the feed trough 27, so that the connecting rod 26 swings to drive the feed trough 27 to flip to one side, so as to achieve the effect of dumping the battery cell 33 onto the inclined plate 16.

[0029] Example 3

[0030] like Figure 1-Figure 4 As shown, a device for automatically putting wound battery cells into boxes includes all the contents of Example 2. In addition, the dust removal device includes a permanent magnet 23, which is fixedly installed directly below the partition 22 and extends to one side between the rotating shaft 25 and the feeding trough 27. A bellows 28 is fixedly installed on the bottom surface of the inclined plate 16, and a fan 29 is installed in the bellows 28. The fan 29 can blow air between the side panels 11 on both sides.

[0031] In the above embodiment, it should be noted that when the connecting rod 26 drives the feeding trough 27 to rotate and pass through the lower side of the partition 22, the magnetic metal particles on the surface of the battery core 33 are adsorbed by the permanent magnet 23, and then the fan 29 is started to blow air between the side panels 11 on both sides to achieve the effect of blowing away the metal particles and dust.

[0032] Example 4

[0033] like Figure 1-Figure 5As shown, a device for automatically inserting wound battery cells into boxes includes all the contents of Example 1. In addition, the box loading device includes a side plate three 13, and the side plate three 13 is fixedly installed on one side of the side plate two 12 close to the end of the inclined plate 16 that is inclined downward. The end of the side plates three 13 on both sides away from the side plate two 12 is fixedly installed with an end plate 18. A rotating plate 17 is arranged between the side plates three 13 on both sides. The rotating plate 17 is rotatably connected to the side plate three 13 on one side through a spring shaft 20. A plurality of circular holes are arranged on the surface of the side plate three 13 on the other side, and the circular holes on the surface of the side plate three 13 on the other side are arranged below the rotating plate 17. The box loading device includes a slide 19, which is fixedly installed on the outer side of one of the side panels 13 that is not connected to the rotating plate 17, one end of the slide 19 is fixedly connected to the circular hole on the surface of the side panel 13, and the other end of the slide 19 is tilted downward. The top surface of the slide 19 is provided with a groove corresponding to the circular hole on the surface of the side panel 13, and the packaging box 31 is arranged on the lower side of the downwardly tilted end of the slide 19, the side panel 2 12, the side panel 3 13 and the end plate 18 are all arranged below the dust cover 14 and fixedly connected to the outer edge of the bottom surface of the dust cover 14, and the dust cover 2 15 is fixedly installed on the top surface of the slide 19.

[0034] In the above embodiment, it should be noted that the spring shaft 20 has a certain elastic force. The spring shaft 20 can drive the rotating plate 17 to bear the total weight of the same number of battery cells 33 as the number of slide grooves on the surface of the slide 19. After the battery cells 33 fall onto the inclined plate 16, they slide along the surface of the inclined plate 16 to the rotating plate 17. When the weight of the battery cells 33 on the rotating plate 17 exceeds the elastic limit of the spring shaft 20, the spring shaft 20 contracts, and the battery cells 33 drive the rotating plate 17 to tilt downward and enter the slide 19 along the circular hole on the surface of the side plate three 13, and then slide into the packaging box 31 along the slide groove on the surface of the slide 19, so as to achieve the effect of completing the boxing of the battery cells 33. The dust cover 2 15 can protect the isolation slide 19 from dust, and the dust cover 1 14 can protect the isolation inclined plate 16 and the rotating plate 17 from dust.

[0035] The use process of the utility model is as follows: a person skilled in the art operates the winding machine 32 to automatically take out the battery cell 33, and the battery cell 33 falls to the loading plate 21 and slides into the feeding trough 27. By starting the motor 24 again to drive the rotating shaft 25 to drive the connecting rod 26 to swing, the feeding trough 27 is rotated from the lower side of the partition 22 to the side of the inclined plate 16 close to the partition 22, and the slightly protruding end of the inclined plate 16 blocks the outer edge of one side of the feeding trough 27, so that the connecting rod 26 swings to drive the feeding trough 27 to flip to one side, and the battery cell 33 is dumped on the inclined plate 16, and the connecting rod 26 drives the feeding trough 27 from the partition When the lower side of the plate 22 rotates and passes by, the permanent magnet 23 absorbs the magnetic metal particles on the surface of the battery core 33, and at the same time starts the fan 29 to blow air between the side plates 11 on both sides to blow away the metal particles and dust on the surface of the battery core 33. After the battery core 33 falls on the inclined plate 16, it slides along the surface of the inclined plate 16 to the rotating plate 17. When the weight of the battery core 33 on the rotating plate 17 exceeds the elastic limit of the spring shaft 20, the spring shaft 20 contracts, and the battery core 33 drives the rotating plate 17 to tilt downward and enter the slide 19 along the circular hole on the surface of the side plate 13, and then slides into the packaging box 31 along the slide groove on the surface of the slide 19.

[0036] The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
