Detailed Implementation Modes

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, the utility model provides a technical solution: an automatic electrical sorting device for lithium batteries, which includes a workbench 1. On both sides of the top of the workbench 1, a screening machine 11 and a support frame 12 are respectively installed. On the upper side of the support frame 12, a placement box 13 is fixedly installed. At the bottom of the placement box 13, a dispersion component 2 is provided. The dispersion component 2 includes a connecting cylinder 21. The connecting cylinder 21 is fixedly connected to the bottom of the placement box 13. An electric motor 22 is installed on the outer wall of the connecting cylinder 21, and the output end of the electric motor 22 extends into the connecting cylinder 21 and is connected to a rotating rod 23. On the surface of the rotating rod 23, partition plates 24 are equidistantly connected. A transportation component 3 is arranged at the bottom of the dispersion component 2. By placing all the lithium batteries in the placement box 13, then starting the electric motor 22 to drive the rotating rod 23 to rotate, the rotating rod 23 drives the partition plates 24 to rotate, so that the lithium batteries enter the connecting cylinder 21 from the placement box 13 and are separated by the partition plates 24 and placed one by one, making the feeding of the lithium batteries smoother and not prone to congestion.

[0023] As an implementation manner in this embodiment, as Figure 3 and Figure 4 shown, at the bottom of the dispersion component 2, a cleaning mechanism for cleaning the batteries is provided. The cleaning mechanism includes a transportation component 3 for transporting the batteries and two cleaning components 5 for wiping the dust off the batteries. The transportation component 3 includes a connecting frame 31 and a transmission component 4. The connecting frame 31 is fixedly connected to the bottom of the connecting cylinder 21. On both sides inside the connecting frame 31, a first transmission wheel 32 and a second transmission wheel 33 are rotatably installed. On the surface of each group of the first transmission wheel 32 and the second transmission wheel 33, a conveyor belt 34 is sleeved, and on the surface of the conveyor belt 34, support plates 35 are equidistantly connected. The transmission component 4 is installed on the outer wall of the connecting frame 31. Both groups of cleaning components 5 are arranged on the lower side of the connecting frame 31. The transmission component 4 includes a housing 41. The housing 41 is installed on the outer wall of the connecting frame 31. On one side of the outer wall of the housing 41, an electric motor 42 is installed. The output end of the electric motor 42 extends into the housing 41 and is connected to a main gear 43. On one side of the housing 41 close to the main gear 43, a secondary gear 44 is rotatably installed, and the secondary gear 44 meshes with the main gear 43. On the mutually remote sides of the main gear 43 and the secondary gear 44, two transmission gears 45 are meshed. Both groups of transmission gears 45 are connected to the two first transmission wheels 32 through rotating shafts. With this structure, by starting the electric motor 42, the electric motor 42 drives the main gear 43 to rotate. The main gear 43 drives the secondary gear 44 to rotate. The main gear 43 and the secondary gear 44 simultaneously drive the two transmission gears 45 to rotate. The transmission gears 45 drive the first transmission wheels 32 to rotate. In this way, the first transmission wheels 32 can drive the second transmission wheels 33 to rotate through the conveyor belt 34, so that the conveyor belt 34 drives the support plates 35 to rotate. In this way, the support plates 35 can drive the lithium batteries to be transported downward, enabling the lithium batteries to be slowly moved and fall into the screening machine 11, which is more convenient for cooperating with the cleaning components 5 to clean both ends of the lithium batteries.

[0024] It should be noted that the secondary gear 44 enables the two sets of transmission gears 45 to rotate in opposite directions, so as to drive the two sets of conveyor belts 34 to rotate relatively, so that the support plates 35 between the two sets of conveyor belts 34 all move downward simultaneously, so that the lithium battery can be transported. Moreover, when the support plates 35 between the two sets of conveyor belts 34 are flush, the gap between the two support plates 35 is smaller than the diameter of the lithium battery, so that the lithium battery is not likely to fall out from the gap between the two support plates 35.

[0025] As an implementation manner in this embodiment, as Figure 5 shown, each cleaning assembly 5 includes a through hole 51 and two fixing rods 52. The through hole 51 is opened on the lower side of the connecting frame 31. The two fixing rods 52 are connected to one side of the outer wall of the connecting frame 31 close to the through hole 51. An installation block 54 is arranged between the two fixing rods 52. And a sponge wipe 55 is adhered to one end of the installation block 54 close to the support plate 35. The sponge wipe 55 passes through the through hole 51 and is inserted into the connecting frame 31. This structure enables the two ends of the lithium battery to contact the sponge wipe 55 during transportation. In this way, the downward moving lithium battery can wipe both ends through the sponge wipe 55, greatly reducing the adhesion of dust at both ends of the lithium battery, making the result more accurate when the lithium battery finally falls into the screening machine 11 for detection and sorting, and greatly increasing the practicability of the device. A clamping groove 53 is opened at one end of each of the two fixing rods 52. Both ends of the installation block 54 are connected with clamping blocks 56, and the clamping blocks 56 are inserted into the clamping grooves 53. This structure enables the sponge wipe 55 to be disassembled, so as to better maintain the cleaning effect of the sponge wipe 55 on both ends of the battery, greatly increasing the convenience of the device. The inner diameter of the clamping groove 53 is adapted to the outer diameter of the clamping block 56, making the installation of the installation block 54 and the sponge wipe 55 more stable.

[0026] Working principle: If it is necessary to conduct electrical sorting on lithium batteries, just place all the lithium batteries in the placement box 13, and then start the first motor 22 to drive the rotating rod 23 to rotate. The rotating rod 23 drives the partition plate 24 to rotate, so that the lithium batteries enter the connecting cylinder 21 from the placement box 13 and are separated by the partition plate 24 and placed one by one. When the partition plate 24 rotates the lithium battery to the lower opening of the connecting cylinder 21, the lithium battery will fall onto the two groups of flush support plates 35. In this way, the support plates 35 can support the lithium batteries. At the same time, start the second motor 42. The second motor 42 drives the main gear 43 to rotate, drives the driven gear 44 to rotate through the main gear 43. The main gear 43 and the driven gear 44 drive the two groups of transmission gears 45 to rotate at the same time. The transmission gears 45 drive the first transmission wheel 32 to rotate. In this way, the first transmission wheel 32 can drive the second transmission wheel 33 to rotate through the conveyor belt 34, so that the conveyor belt 34 drives the support plates 35 to rotate. In this way, the support plates 35 can drive the lithium batteries to be transported downward. During the transportation, both ends of the lithium battery will contact the sponge wipes 55. In this way, the lithium battery moving downward can wipe both ends through the sponge wipes 55, greatly reducing the adhesion of dust at both ends of the lithium battery, making the result more accurate when the lithium battery finally falls into the screening machine 11 for detection and sorting, and greatly increasing the practicability of the device;

[0027] In addition, if it is necessary to replace the sponge wipes 55, just pull the installation block 54 outward. The installation block 54 drives the clamping block 56 and the sponge wipes 55 to move outward until the clamping block 56 is pulled out of the clamping groove 53, and the sponge wipes 55 can be disassembled and replaced. In this way, the cleaning effect of the sponge wipes 55 on both ends of the battery can be better maintained, and the convenience of the device is greatly increased.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
