[0068] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0069] like Figures 1 to 3 As shown, the cleaning mechanism 10 in the embodiment of the present application includes an air block 1, an air blowing connector 2 and an air extraction connector 3, wherein:

[0070] An air blowing cavity 4 and an air pumping cavity 5 are provided in the air block 1 .

[0071] An air blowing path 6 is also provided in the air block 1 , and the air blowing path 6 is communicated with the air blowing cavity 4 . The air blowing path 6 has an air blowing port 61 located at the bottom of the air block.

[0072] An air suction path 7 is also provided in the gas block 1 . The air suction path 7 is connected to the air suction cavity 5 . The air suction path 7 has an air suction port 71 located at the bottom of the gas block 1 .

[0073] The blowing connector 2 is installed on the gas block 1 and communicated with the blowing cavity 4. The blowing connector 2 is used to pass gas into the blowing cavity 4 so that the blowing port 61 blows toward the target table surface to blow away impurities on the target table surface.

[0074] The air extraction joint 3 is installed on the gas block 1 and communicated with the air extraction cavity 5. The air extraction joint 3 is used to evacuate the air extraction cavity 5 so that the air suction port 71 absorbs impurities blown away from the target table by the air blowing port.

[0075] The cleaning mechanism 10 provided in the present application can be conveniently integrated into a cell printing device, and can blow away impurities on the printing table (i.e., the target table) from the printing table, and promptly absorb the blown impurities, thereby ensuring the cleaning effect of the printing table. Of course, the cleaning mechanism 10 provided in the present application can also be used to clean other tables.

[0076] like Figure 3 As shown, optionally, the straight lines of the airflow directions of the blowing port 61 and the air inlet 71 intersect at one point, and the width of the air inlet 71 is greater than the width of the blowing port 61. The air inlet 71 is set to be wider to ensure that the air inlet 71 can absorb all impurities blown away from the target table surface and prevent the impurities from escaping and falling back onto the target table surface. If the blowing port 61 is set to be narrower, the high-speed airflow blown out of the blowing port 61 can form a sharp wind knife, thereby improving the effect of blowing away impurities.

[0077] like Figure 3 As shown, optionally, the air extraction path 7 is arranged in the vertical direction, so that the air suction port 71 extracts air vertically upward. The air blowing path 6 is inclined toward the air extraction path, so that the air blowing port 61 is inclined to blow toward the target table. The air extraction path of the air suction port 71 and the air blowing path of the air blowing port 61 intersect in a strip area, and the strip area is located on the target table.

[0078] Since the suction path of the air inlet 71 and the blowing path of the air inlet 61 intersect on the target table, the impurities blown away from the target table by the air inlet 61 are immediately sucked away by the air inlet 71, thereby further improving the cleaning effect. Optionally, the target table is controlled to pass slowly from the bottom of the cleaning mechanism 10, and the extension direction of the strip area is perpendicular to the moving direction of the target table, so that the strip area can sweep the entire target table, thereby completing the comprehensive cleaning of the target table. Of course, the cleaning mechanism 10 can also be controlled to pass slowly from the top of the target table.

[0079] Continue to refer Figures 1 to 3 As shown, optionally, the gas block 1 includes a top plate 11, a first side plate 12, a second side plate 13, a partition plate 14, a first end plate 15 and a second end plate 16, wherein: the first side plate 12 and the second side plate 13 are connected side by side on the bottom surface of the top plate 11 along a first horizontal direction, the partition plate 14 is arranged between the lower part of the first side plate 12 and the lower part of the second side plate 13, the first end plate 15 is arranged at the first end of the first side plate 12, the second side plate 13 and the partition plate 14, and the second end plate 16 is arranged at the second end of the first side plate 12, the second side plate 13 and the partition plate 14.

[0080] The bottom surface of the top plate 11, the inner surface of the first side plate 12, the inner surface of the second side plate 13, the upper surface of the partition plate 14, the inner surface of the first end plate 15 and the inner surface of the second end plate 16 together form the suction cavity 5. The suction air path 7 is located between the second side surface of the partition plate 14 and the inner surface of the second side plate 13. The blowing cavity 4 and the blowing air path 6 are located between the first side surface of the partition plate 14 and the inner surface of the first side plate 12.

[0081] The gas block 1 is configured as a split structure composed of a top plate 11, a first side plate 12, a second side plate 13, a partition plate 14, a first end plate 15 and a second end plate 16, which facilitates the production and molding of the vacuum chamber, the vacuum air path, the blowing chamber and the blowing air path, and is easy to install and maintain.

[0082] like Figure 3 to Figure 4 As shown, optionally, the second side surface of the partition 14 and the inner surface of the lower portion of the second side plate 13 are both vertical surfaces, and a gap is maintained between the second side surface of the partition 14 and the inner surface of the lower portion of the second side plate 13, thereby forming a vertical exhaust air path 7.

[0083] like Figures 3 to 9As shown, optionally, a groove 141 is provided on the first side surface of the partition 14, and the inner surface of the first side plate 12, the inner surface of the first end plate 15 and the inner surface of the second end plate 16 block the groove 141, thereby forming the blowing cavity 4. A first inclined surface 142 inclined toward the second side plate is formed at the lower end of the first side surface of the partition 14, and a second inclined surface 121 abutting against the first inclined surface 142 is formed at the lower end of the inner surface of the first side plate 12, and a blowing air path 6 is formed between the first inclined surface 142 and the second inclined surface 121.

[0084] Optionally, the cleaning mechanism 10 in the embodiment of the present application further includes a filter element 8 disposed in the air extraction chamber, the air extraction connector 3 is connected to the filter element 8 , and the air extraction connector 3 extracts air from the air extraction chamber 5 through the filter element 8 .

[0085] The air extraction joint 3 extracts air from the air extraction chamber 5 through the filter element 8 , so that the impurities sucked into the air extraction chamber 5 are trapped in the filter element 8 , thereby preventing the impurities from entering the air extraction device through the air extraction joint 3 .

[0086] Optionally, the filter element 8 includes at least one of the following options: hollow PP filter element, polyester fiber filter paper, high-density metal filter. Using at least one of the above filter elements can effectively prevent dust and impurities from entering the exhaust pipeline, and has low cost, good effect, and is easy to replace.

[0087] The present application also provides a battery sheet printing device, such as Fig.10 As shown, the cell printing device in the embodiment of the present application includes an input mechanism 20, a printing machine 30, a printing mechanism 40, an output mechanism 50 and a cleaning mechanism 10 provided in any of the above embodiments, wherein:

[0088] The input mechanism 20 is located in front of the printing machine 30 and is used to input the battery cells to be printed.

[0089] The printing station is arranged between the input mechanism 20 and the output mechanism 50. The printing station 30 includes a mounting bracket and at least one group of printing stations connected to the mounting bracket. Each group of printing stations includes a first printing station 31 and a second printing station 32. The first printing station 31 is arranged close to the input mechanism 20, and the second printing station 32 is arranged close to the output mechanism 50. The first printing station 31 and the second printing station 32 are configured to receive the battery cells to be printed from the input mechanism 20, respectively, and to transport the received battery cells to be printed to the printing station. The first printing station 31 and the second printing station 32 are also configured to transport the printed battery cells from the printing station to the output mechanism 50, respectively.

[0090] The printing mechanism 40 is disposed above the printing station, wherein the printing mechanism 40 is configured to print the battery cells on the first printing stage 31 moved to the printing station, and to print the battery cells on the second printing stage 32 moved to the printing station.

[0091] An input avoidance space A is provided below the output end of the input mechanism 20. When the second printing table 32 receives the battery cells to be printed from the output end of the input mechanism 20, the first printing table 31 is configured to move into the input avoidance space B to avoid the second printing table 32. When the second printing table 32 moves the received battery cells to be printed toward the printing station, the first printing table 31 leaves the input avoidance space A and receives the battery cells to be printed from the discharge end of the input mechanism 20.

[0092] An output avoidance space B is provided below the input end of the output mechanism 50. After the second printing table 32 delivers the printed battery cells to the input end of the output mechanism 50, the second printing table 32 moves into the output avoidance space B to avoid the first printing table 31, so that the first printing table 31 delivers the printed battery cells to the input end of the output mechanism 50.

[0093] A cleaning mechanism 10 is provided at least at one of the output end of the input mechanism 20 and the input end of the output mechanism 30 . The cleaning mechanism 10 is used to clean the first printing table 31 and the second printing table 32 .

[0094] The cell printing device in the embodiment of the present application is provided with a cleaning mechanism 10 at least at one of the output end of the input mechanism 20 and the input end of the output mechanism 50. During each round of printing, the cleaning mechanism 10 can automatically clean the first printing table 31 and the second printing table 32, thereby ensuring that the table surfaces of the first printing table 31 and the second printing table 32 remain clean.

[0095] Optionally, a cleaning mechanism 10 is provided at both the output end of the input mechanism 20 and the input end of the output mechanism 50. Specifically, the cleaning mechanism 10 provided at the output end of the input mechanism 20 is located above the input avoidance space A. When the first printing table 31 enters and exits the input avoidance space A, the cleaning mechanism 10 cleans the first printing table 31. The cleaning mechanism 10 provided at the input end of the output mechanism 50 is located above the output avoidance space B. When the second printing table 32 enters and exits the input avoidance space B, the cleaning mechanism 10 cleans the second printing table 32.

[0096] Optionally, the first printing table 31 and the second printing table 32 have the same structure. Taking the first printing table 31 as an example, it includes a translation drive mechanism 311, a lifting drive mechanism 312 and a carrier 313, wherein: the translation drive mechanism 311 is installed on the mounting bracket, the lifting drive mechanism 312 is connected to the driving end of the translation drive mechanism 311, and the carrier 313 is connected to the driving end of the lifting drive mechanism 312. The carrier 313 is used to carry the battery cells, the translation drive mechanism 311 is used to drive the carrier 313 to translate, and the lifting drive mechanism 312 is used to drive the carrier 313 to lift.

[0097] Through the cooperative driving of the translation drive mechanism 311 and the lifting drive mechanism 312 , the carrier platform 313 transports the battery cells to be printed from the input mechanism 20 to the printing station for printing, and transports the printed battery cells to the output mechanism 50 .

[0098] Both the translation drive mechanism 311 and the lifting drive mechanism 312 can adopt various existing linear drive modules, such as a cylinder drive module, a screw motor drive module, etc.

[0099] Continue to refer Fig.10 As shown, optionally, the output end of the input mechanism 20 includes a first export conveyor belt 21 and a second export conveyor belt 22 arranged side by side for carrying battery cells, and the input end of the output mechanism 50 includes a first import conveyor belt 51 and a second import conveyor belt 52 arranged side by side for carrying battery cells.

[0100] The first and second grooves are provided on the carriers 313 of the first printing station 31 and the second printing station 32. When the lifting drive mechanism 312 drives the carrier 313 to rise to a first predetermined height toward the output end of the input mechanism 20, the first and second output conveyor belts 21 and 22 sink into the first and second grooves respectively, so that the battery cells on the output end of the input mechanism 20 are lifted onto the carrier 313.

[0101] When the lifting drive mechanism 312 drives the supporting platform 313 to descend to a second predetermined height away from the input end of the output mechanism 50, the first import conveyor belt 51 and the second import conveyor belt 52 float upward out of the first groove and the second groove respectively, so that the battery cells on the supporting platform 313 fall onto the input end of the output mechanism 50.

[0102] Taking the first printing table 31 as an example, when the first printing table 31 needs to receive the battery cells to be printed from the output end of the input mechanism 20, the lifting drive mechanism 312 first drives the carrier 313 to descend to a low position, and then the translation drive mechanism 311 drives the carrier 313 to translate toward the output end of the input mechanism 20 until the carrier 313 translates to the bottom of the output end of the input mechanism 20. Then, the lifting drive mechanism 312 drives the carrier 313 to rise to a first predetermined height. During this process, the first output conveyor belt 21 and the second output conveyor belt 22 at the output end of the input mechanism 20 respectively sink downward into the first groove and the second groove of the carrier 313, and the two battery cells carried on the output end of the input mechanism 20 are lifted away from the output end of the input mechanism 20 by the carrier 313, that is, the two battery cells to be printed are transferred from the output end of the input mechanism 20 to the carrier 313 of the first printing table 31.

[0103] Still taking the first printing table 31 as an example, after the printing mechanism 40 completes printing on the battery cell on the first printing table 31, the lifting drive mechanism 312 first drives the carrier 313 to descend and return to its original position, so that the first groove and the second groove on the carrier 313 are at the same height as the first introduction conveyor belt 51 and the second introduction conveyor belt 52 at the input end of the output mechanism 50. Then, the translation drive mechanism 311 drives the carrier 313 to move toward the input end of the output mechanism 50. During this process, the first introduction conveyor belt 51 and the second introduction conveyor belt 52 at the input end of the output mechanism 50 are respectively inserted into the first groove and the second groove of the carrier 313.
