[0030] Referring to Figure 1 , an embodiment of the present application provides a cleaning device for a lithium battery logistics tray, including: a dust removal cover and a pallet 7. The pallet 7 is arranged on the lower side of the dust removal cover. The pallet 7 is driven by a cylinder 8 to automatically lift the logistics tray 15, lift the logistics tray 15 below the dust removal cover, and the dust removal cover covers at least a part of the surface of the logistics tray 15.

[0031] Specifically, as Figure 1 shown, the dust removal cover includes a cover body. The cover body includes a dust outlet 2 and a dust suction port 3. The dust suction port 3 is arranged to cover at least a part of the surface of the logistics tray 15, so that a sealed environment is formed among the cover body, the logistics tray 15, and the pallet 7. The dust outlet 2 is connected to an external dust removal pipeline to discharge dust and other foreign matters outside the dust suction port 3.

[0032] In a possible embodiment, the dust outlet 2 is arranged at the top of the hood body, the dust suction port 3 is arranged at the bottom of the hood body, the dust outlet 2 and the dust suction port 3 are integrally formed, and the dust outlet 2 is a vacuum dust outlet.

[0033] In a possible embodiment, a connecting pipe 1 is provided between the dust outlet 2 and an external dust removal pipeline. One end of the connecting pipe 1 is connected to the dust outlet 2, and the other end is connected to the external dust removal pipeline.

[0034] In order to make the connection between the connecting pipe 1 and the dust outlet 2 tighter and prevent foreign matters such as dust from escaping from the connection between the connecting pipe 1 and the dust outlet 2, a fastener 14 is provided on the outer surface of the connection between the connecting pipe 1 and the dust outlet 2 for locking the connecting pipe 1 and the dust outlet 2 and sealing the connection between the two.

[0035] The inside of the dust suction port 3 is hollow, and at least one air blowing port is provided in the dust suction port 3. The at least one air blowing port can blow air towards the surface of the logistics tray 15 to clean the surface of the logistics tray 15, and the at least one air blowing port is communicated with an external air duct 4.

[0036] In a possible embodiment, the external air duct 4 is connected to the dust suction port 3 and is arranged outside the dust suction port 3. The air blowing port is provided with an air knife 5. One end of the external air duct 4 is communicated with an air source, and the other end is communicated with the air knife 5. The air knife 5 includes an air inlet, an air duct and an air outlet. The air inlet is connected to the external air duct 4, and the air outlet points to the logistics tray 15, so as to blow and clean foreign matters such as dust on the surface of the logistics tray 15.

[0037] In order to improve the cleaning strength, the air outlet of the air knife 5 is arranged close to the bottom of the dust suction port 3, and the air outlet of the air knife 5 can be adjusted at different angles to adjust the wind direction so as to achieve comprehensive cleaning of the logistics tray 15.

[0038] The lithium battery logistics tray cleaning device is at least connected to one external air duct 4, and the at least one external air duct 4 can be arranged at any position outside the dust suction port 3. In a possible embodiment, two external air ducts 4 are provided outside the dust suction port 3, and the two external air ducts 4 are arranged on opposite sides of the dust suction port 3.

[0039] The lithium battery logistics tray cleaning device is provided with at least one air knife 5. The at least one air knife 5 can be arranged at any position within the dust suction port 3. When two or more air knives 5 are provided, the two or more air knives 5 are arranged oppositely at any position within the dust suction port 3. In a possible embodiment, two air knives 5 are arranged within the dust suction port 3. The two air knives 5 are connected to the inner wall of the dust suction port 3, and the two air knives 5 are arranged oppositely on the inner side of the dust suction port 3. As Figure 1 shown, the present application shows a position setting diagram of an external air duct 4 and an air knife 5.

[0040] As Figure 1 shown, the logistics tray 15 is lifted by a pallet 7. The pallet 7 is driven by a cylinder 8 to move upward, lifting the logistics tray 15 upward until the dust suction port 3 covers at least a part of the surface of the logistics tray 15, so as to form a sealed cleaning environment between the cover body and the logistics tray 15 or the pallet 7, improving the cleaning strength.

[0041] The cylinder 8 includes a piston rod 9 arranged inside the cylinder 8 and extending to the outside of the cylinder 8, a guide rod 10 arranged outside the cylinder 8, and an air inlet pipe 11 and an air outlet pipe 12 communicated with an external air source outside the cylinder.

[0042] The pallet 7 is arranged at the top of the cylinder 8 and is connected to the piston rod 9 and the guide rod 10. In a possible embodiment, the pallet 7 is connected to the piston rod 9 and the guide rod 10 by hexagon head screws.

[0043] The air inlet pipe 11 is arranged near the bottom of the cylinder 8, the air outlet pipe 12 is arranged near the top of the cylinder 8, and a pneumatic pressure regulating valve 12 is connected to the air inlet pipe 11.

[0044] The working principle of the lithium battery logistics tray cleaning device in the above embodiment is as follows: The logistics tray 15 is placed on the pallet 7. The air inlet pipe 11 is connected to an air source to allow gas to enter the cylinder 8. The air pressure is adjusted through the pneumatic pressure regulating valve 12 to apply pressure to the piston. The piston will push the piston rod 9 to move outward from the cylinder 8, thereby realizing the jacking of the pallet 7, so that the pallet 7 rises until at least a part of the surface of the logistics tray 15 is covered by the dust suction port 3 to form a sealed environment. After sealing, the air knife 5 starts to work, and at the same time, the external dust removal pipeline connected to the dust outlet 2 is synchronously turned on for dust suction, and the dust suction wind speed is greater than the air outlet wind speed of the air knife 5.

[0045] Referring to Figure 2 , in order to further improve the sealing performance of the dust suction port 3 covering the logistics tray 15, in a possible embodiment, a sealing strip is arranged at the bottom of the dust suction port 3. As Figure 2As shown, the sealing strip 6 is provided at the bottom edge inside the dust suction port 3, and there are various connection methods between the dust suction port 3 and the sealing strip 6. In a possible embodiment, the sealing strip 6 is connected to the dust suction port 3 by glue. By applying glue to the bottom edge of the dust suction port 3, the sealing strip 6 can be bonded and fixed to the dust suction port 3. The fixing method is simple and the cost is low.

[0046] The sealing strip 6 is used to connect with the logistics tray 15, so as to seal the cleaning environment when cleaning the logistics tray 15. The shape of the sealing strip 6 is set according to the shape and size of the bottom of the dust suction port 3. As Figure 2 shown, the dust suction port 3 is generally in an inverted conical shape, and the bottom of the dust suction port 3 is square. Then the shape of the sealing strip 6 can be set as square or other shapes. Preferably, the sealing strip 6 is set as a U-shaped structure, which can achieve sealing and the installation method is simple.

[0047] It should be noted that the thickness and width of the sealing strip 6 are set in combination with the actual sizes of the cover body and the logistics tray 15 to ensure that the sealing strip 6 fits the logistics tray 15 to achieve sealing. Since the sizes of different cover bodies and logistics trays 15 are different, the thickness and width of the sealing strip 6 will necessarily be different. Technicians can set according to the actual situation, and this application does not make specific limitations here. Since the sealing strip 6 is used to connect with the logistics tray 15 to form a sealed cleaning environment, compared with the method of directly cleaning the tray inside the cover body, it can avoid the escape of dust and foreign objects due to gaps in the dust removal environment, reduce the risk of dust and foreign objects adhering to the air again and falling into the logistics tray, and further improve the cleaning strength.

[0048] The working principle of the lithium battery logistics tray cleaning device in the above embodiment is as follows: The logistics tray 15 is placed on the pallet 7. The air inlet pipe 11 is connected to the air source to make gas enter the cylinder 8. The air pressure is adjusted by the air pressure regulating valve 12 to apply pressure to the piston. The piston will push the piston rod 9 to move outside the cylinder 8, so as to realize the jacking of the pallet 7, so that the pallet 7 rises until at least part of the logistics tray 15 is connected to the sealing strip 6 to achieve sealing. After sealing, the air knife 5 starts to work, and at the same time, the external dust removal pipeline connected to the dust outlet 2 is synchronously opened for dust suction, and the dust suction wind speed is greater than the air outlet wind speed of the air knife 5.

[0049] In the present utility model, specific embodiments are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
