[0002] Power batteries are the power sources that provide power to tools. They generally refer to power lithium batteries, which have advantages such as long service life, high temperature resistance, large capacity, and light weight. Therefore, they are widely used in the field of new energy technology. Most existing power lithium batteries have a square structure. In the production process of power lithium batteries, barcodes, trademarks, QR codes and other information markings need to be printed on their cells.
[0003] A patent, CN219564531 U, discloses a battery cell information coding device, comprising: a frame, two or more conveying components, a guiding component, and a coding component. The conveying components are arranged in the frame, horizontally connected sequentially, with the speed of the preceding conveying component greater than that of the following one. The guiding component is positioned on the frame above the conveying components and guides the battery cells. The coding component is also positioned on the frame above the conveying components and prints information onto the surface of the battery cells. When a battery cell is placed on the conveying components, the differential speed transmission of the conveying components quickly increases the conveying distance between the cells. Guided by the guiding component, each battery cell passes under the coding component, which then codes the cell, printing the information onto its surface. This battery cell information coding device can replace manual operation of each battery cell individually, thereby improving battery cell production efficiency.
[0004] However, in this existing technology, the dust on the surface of the battery cell cannot be cleaned before printing, and dust is easily attached to the printing position before printing, thus affecting the printing quality.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0024] like Figures 1 to 4As shown, this utility model discloses a battery cell surface inkjet printing mechanism, comprising: a machine base 1; a rotary table 2 rotatably mounted on the machine base 1; placement slots 201 formed on the rotary table 2, with four placement slots 201 equidistantly spaced along the circumference of the rotary table 2; a motor 202 that drives the rotary table 2 to rotate, the motor 202 being fixedly mounted on the machine base 1, and preferably a stepper motor, which rotates 90 degrees each time by adjusting its parameters; an inkjet printing assembly 4 disposed on the machine base 1; and a curing lamp disposed on the machine base 1 for drying the ink after inkjet printing.
[0025] The printing assembly 4 includes: a bracket 401; an electric push rod 402 fixedly mounted on the bracket 401; a printer 403 fixedly mounted on the output end of the electric push rod 402; and a cleaning assembly 5 disposed on the bracket 401 for cleaning dust from the surface of the battery cells on the placement slot 201.
[0026] When printing on the cells of a power lithium battery, the cells are placed in the placement slot 201. The motor 202 drives the rotary table 2 to rotate 90 degrees each time. When the cells rotate to the bottom of the printing assembly 4, the electric push rod 402 is activated. The output end of the electric push rod 402 pushes the printer 403 to descend, so that the printer 403 prints on the surface of the cells on the placement slot 201. After printing is completed, the printed cells are rotated to the curing lamp for ink drying.
[0027] The cleaning assembly 5 includes: a movable plate 501 fixedly mounted on the printer 403, with one end of the movable plate 501 slidably mounted on the bracket 401; a movable part 502 fixedly mounted on the movable plate 501; a fixed part 503 fitted onto the movable part 502, with one side of the fixed part 503 fixedly mounted on the bracket 401; a piston 504 fixedly mounted on the movable part 502; an air blowing pipe 505 communicating with the fixed part 503; and an alignment assembly 3 for aligning the battery cells inside the placement slot 201.
[0028] As the printer 403 descends, the movable plate 501 fixed on the printer 403 drives the moving part 502 at the bottom to move down, causing the piston 504 fixed on the surface of the moving part 502 to squeeze the air inside the fixed part 503, so that the air is ejected through the air blowing pipe 505, blowing away the dust on the surface of the battery cell, thereby removing the dust from the battery cell and further ensuring the quality of the printing.
[0029] It should be added here that a sealing ring is provided between the opening of the fixing member 503 and the surface of the moving member 502, and the inner ring of the sealing ring is attached to the surface of the moving member 502, while the outer ring of the sealing ring is fixedly installed at the opening of the fixing member 503. By setting the sealing ring, the sealing performance between the fixing member 503 and the moving member 502 is improved, and when the piston 504 on the moving member 502 compresses the air inside the fixing member 503, the compressed air is reduced from flowing out from the gap between the moving member 502 and the fixing member 503.
[0030] To ensure that the printing position is centered, the code pattern is consistent, and the printing is not tilted during battery cell printing;
[0031] The centering component 3 includes: two clamping plates 301 symmetrically slidably mounted on the placement groove 201; a hinge rod 302 hinged to the bottom of the clamping plates 301; a push rod 303 hinged between the two hinge rods 302; an extrusion block 304 fixedly mounted on one end of the push rod 303; a guide sleeve 305 for guiding the movement of the push rod 303, with the top of the guide sleeve 305 fixedly mounted on the bottom of the rotary table 2; and a spring 306 fitted on the push rod 303, with one end of the spring 306 fixedly connected to the surface of the guide sleeve 305 and the other end of the spring 306 fixedly connected to the surface of the extrusion block 304.
[0032] As the moving part 502 descends, its circular bottom presses against the inclined surface of the corresponding pressing block 304, causing the pressing block 304 to move the push rod 303. At this time, the two hinged rods 302 symmetrically hinged on the push rod 303 move the corresponding clamping plate 301, causing the two clamping plates 301 to move closer to each other simultaneously, thus centering and clamping the battery cell on the placement slot 201. This ensures that the battery cell's printing position is centered and the code pattern is consistent, thereby improving the printing quality.
[0033] It should be noted that the top of the extrusion block 304 is set as an inclined surface, and the bottom of the moving part 502 is set as a circle that matches the inclined surface of the top of the extrusion block 304. When the printer 403 drives the moving part 502 fixed on the movable plate 501 to descend, the moving part 502 presses against the inclined surface of the extrusion block 304 directly below, thereby causing the extrusion block 304 to drive the push rod 303 to move. This causes the hinge rod 302 symmetrically hinged on the push rod 303 to drive the clamping plate 301 to move, which can automatically center the battery cell.
[0034] It should be added that the surface of the machine base 1 is provided with a through groove 6, and the through groove 6 is located directly below the moving part 502; the through groove 6 is provided to prevent the moving part 502 from descending and contacting the surface of the machine base 1, thus preventing interference.
[0035] Working principle: When the power is turned on, the battery cell of the power lithium battery is placed in the placement slot 201. The motor 202 drives the rotary table 2 to rotate 90 degrees each time. When the battery cell rotates to the bottom of the printing assembly 4, the electric push rod 402 is activated. The output end of the electric push rod 402 pushes the printer 403 to descend, so that the printer 403 prints on the surface of the battery cell in the placement slot 201. During the descent of the printer 403, the movable plate 501 fixed on the printer 403 drives the bottom moving part 502 to move down, so that the piston 504 fixed on the surface of the moving part 502 presses against the inside of the fixed part 503. Air is blown out through the air pipe 505 to blow away dust from the surface of the battery cell. In addition, as the moving part 502 descends, its circular bottom presses against the inclined surface of the corresponding pressing block 304, causing the pressing block 304 to move the push rod 303. At this time, the two hinged rods 302 symmetrically hinged on the push rod 303 move the corresponding clamping plate 301, so that the two clamping plates 301 move closer to each other at the same time, and center and clamp the battery cell on the placement slot 201. This ensures that the printing position of the battery cell is centered and the code is consistent. Finally, after the printing is completed, the printed battery cell is rotated to the curing lamp for ink drying.
