[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] A lithium-ion battery dust cleaning device comprises a cross support plate 11, a hollow support plate 12, an extrusion convex plate 13, a bearing seat 31 and a bidirectional lead screw 32; the upper end of each support plate of the cross support plate 11 is fixedly connected to the corresponding hollow support plate 12 by welding, and a bearing seat 31 is provided in the middle of the upper surface of the cross support plate 11 by welding, and the bearing seat 31 and the middle parts of two vertically arranged bidirectional lead screws 32 are rotatably connected through bearing holes, and the two ends of each bidirectional lead screw 32 are respectively screwed with the corresponding extrusion convex plate 13, and each extrusion convex plate 13 is slidably connected to the corresponding hollow support plate 12 through a straight groove.

[0026] The cross support plate 11 plays a supporting and fixing role. The lithium-ion battery is placed on the four hollow support plates 12, and the sliding of the four extrusion convex plates 13 is utilized to realize the extrusion and fixing processing of the lithium-ion battery. When the lithium-ion battery is fixed, the wind blows onto the lithium-ion battery to blow away the dust on the lithium-ion battery, thereby completing the dust cleaning processing of the lithium-ion battery and reducing the workload of the workers.

[0027] The bearing seat 31 can provide rotation space for the two bidirectional screws 32. The threads at both ends of the bidirectional screws 32 have opposite rotation directions. After rotating the bidirectional screws 32, the extrusion convex plates 13 thereon can be driven to move inward or outward at the same time, thereby ensuring that the four extrusion convex plates 13 can all contact with the lithium-ion battery, thereby completing the fixation of the lithium-ion battery.

[0028] The two bidirectional lead screws 32 have a height difference to ensure that the two bidirectional lead screws 32 rotate normally.

[0029] The contact surface between each of the extrusion convex plate 13 and the lithium-ion battery is fixed with a rubber pad by glue, which can prevent the extrusion convex plate 13 from directly contacting the lithium-ion battery and play a role in protecting the lithium-ion battery.

[0030] The cross support plate 11 is rotatably arranged on the upper end of the rotating support circular plate 21 via a central axis.

[0031] The rotating support circular plate 21 plays a role of bearing and fixing. When the cross support plate 11 rotates, it can drive the lithium-ion battery to rotate, allowing wind to act on the rotating lithium-ion battery, thereby ensuring the cleaning efficiency of the lithium-ion battery.

[0032] The lower end of the rotating support circular plate 21 is fixedly connected to the vertically arranged reduction motor 41 through a flange plate, and the output shaft of the reduction motor 41 is fixedly connected to the middle part of the cross support plate 11 through a keyway and a retaining spring.

[0033] The cross support plate 11 is driven to rotate by the reduction motor 41, and finally the lithium-ion battery is driven to rotate.

[0034] The lower end of the rotating support circular plate 21 is fixedly connected to a plurality of supporting vertical legs 51 arranged in an array by welding.

[0035] The plurality of supporting vertical legs 51 are used to place the rotating circular plate 21 firmly on the ground. Only when the rotating circular plate 21 is fixed can the lithium-ion battery be cleaned.

[0036] The lower end of each of the supporting vertical legs 51 is fixedly connected to the corresponding circular anchor plate 61 by welding, and each of the circular anchor plates 61 is provided with a plurality of mounting circular holes.

[0037] A plurality of bolts are passed through a plurality of mounting circular holes and connected to the ground, so that the plurality of supporting vertical legs 51 are firmly fixed on the ground, and finally the device is firmly fixed.

[0038] The lower end of the transfer circular plate 21 is fixedly connected to the upper end of the vertically arranged circular tube 71 by welding, and the lower end of the circular tube 71 is slidingly sleeved on the outer side of the vertically arranged supporting slide column 72 by a plurality of keys and key grooves, and the lower end of the supporting slide column 72 is fixedly connected to one end of the horizontally arranged supporting plate 73 by welding, and the other end of the supporting plate 73 is fixedly connected to the lower end of the air transfer pipe 74 by welding, and the outer wall of the air transfer pipe 74 is provided with a plurality of ventilation holes penetrating its wall thickness.

[0039] The circular tube 71 provides a sliding space for the supporting sliding column 72 , the supporting sliding column 72 provides a fixed space for the supporting plate 73 , and the supporting plate 73 provides a fixed space for the air transmission pipe 74 .

[0040] The top of the air transfer duct 74 is connected to the blower through a duct, and the gas entering the air transfer duct 74 is discharged through a plurality of vents, and the discharged gas can act on the rotating lithium-ion battery. In addition, the relative positions of the circular tube 71 and the supporting slide column 72 can be changed according to the different heights of the lithium-ion batteries, so that the height of the air transfer duct 74 can be changed through the supporting plate 73, and the distance between the air transfer duct 74 and the upper surface of the lithium-ion battery can be changed, so as to complete the thorough cleaning of the upper surfaces of lithium-ion batteries of different thicknesses, because the closer the distance, the better the cleaning effect, and most of the dust on the lithium-ion battery is located on the upper surface of the lithium-ion battery, so it is very necessary to thoroughly clean the upper surface of the lithium-ion battery.

[0041] The supporting slide column 72 is screwed onto the outer side of the lifting screw 81 , and the upper end of the lifting screw 81 is arranged inside the round tube 71 . The upper end of the lifting screw 81 is rotatably connected to the transfer circular plate 21 through a bearing hole.

[0042] After the lifting screw 81 is rotated, the supporting slide column 72 can be driven to slide in the circular tube 71, thereby driving the air transmission pipe 74 to change height through the supporting plate 73, so as to achieve the cleaning process of the upper surface of lithium-ion batteries with different thicknesses.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent conditions of the claims are included in the present invention.
