[0028] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs.

[0029] Example 1

[0030] like Figure 1 , Figure 2 As shown, this embodiment proposes a brush cleaning mechanism 28, including a mounting plate 29, a cleaning transverse movement assembly, a cleaning lifting assembly and a cleaning plate 7; the cleaning transverse movement assembly includes a transverse movement cylinder 4, a transverse movement rail 14 and a transverse movement plate 31, the transverse movement cylinder 4 is installed on the end surface of the fixed plate, the transverse movement rail 14 is installed on the side of the mounting plate 29, the transverse movement plate 31 is slidably installed on the transverse movement rail 14 and connected to the transverse movement cylinder 4; the cleaning lifting assembly includes a lifting cylinder 12 and a connecting block 15, the lifting cylinder 12 is installed on the transverse movement plate 31, and the connecting block 15 is installed at the bottom of the lifting cylinder 12; the cleaning plate 7 is installed on the connecting block 15, and the top surface of the cleaning plate 7 is provided with a cleaning groove for cleaning the brush.

[0031] The brush cleaning mechanism 28 is fixed to the device base plate through the mounting plate 29 to realize the positioning of the overall structure. The cleaning transverse movement assembly is driven by the transverse movement cylinder 4 to drive the transverse movement plate 31 to move linearly along the transverse movement track 14, forming a horizontal movement functional unit. The cleaning lifting assembly drives the connecting block 15 to move vertically through the lifting cylinder 12, driving the cleaning plate 7 to form a three-dimensional motion trajectory. The cleaning groove set on the top surface of the cleaning plate 7 forms a geometric matching relationship with the cleaning brush 10, and the pollutant removal is realized by immersion and rotation.

[0032] By designing a rotating wiping cleaning station cleaning slot 20 mechanism for the liquid injection equipment, the grinding head is cleaned regularly to ensure that the grinding head is not contaminated when cleaning the liquid injection port of the battery cell 9, thereby ensuring the efficiency of automatic cleaning of the equipment, improving efficiency, replacing manual wiping, reducing manpower at the unloading end, and saving costs.

[0033] There are multiple cleaning grooves, which are distributed in a linear array along the length direction of the cleaning plate 7. The interior of the cleaning plate 7 has a flow channel, which is connected to each cleaning groove.

[0034] The cleaning plate 7 adopts a multi-cavity parallel design, and multiple cleaning slots are linearly distributed to form a cleaning station array to achieve batch processing capabilities. The multi-station structure can clean multiple brushes at the same time, significantly improving the cleaning efficiency and avoiding the equipment waiting time caused by a single station. Multiple cleaning slots are connected through flow channels to ensure that the cleaning liquid can evenly cover each cleaning slot, thereby improving the cleaning effect of the brush.

[0035] A fixing frame 37 is installed on the side of the connecting block 15 , a first liquid level gauge 24 is disposed at the outer end of the fixing frame 37 , a detection port 23 is disposed at one end of the cleaning plate 7 , and the first liquid level gauge 24 is connected to the detection port 23 of the cleaning plate 7 .

[0036] The fixed frame 37 adopts a cantilever installation structure, and the first liquid level sensor 24 is connected to the detection port 23 through a flexible conduit to form a non-contact liquid level detection system, which can monitor the liquid level of the cleaning liquid in the cleaning plate 7 in real time. When the liquid level reaches the set value, the liquid intake can be automatically stopped to ensure that the immersion depth of the brush meets the process requirements, ensure the smooth progress of the cleaning process, avoid incomplete cleaning due to insufficient liquid level, and improve the intelligence level of the entire cleaning mechanism.

[0037] The end surface of the mounting plate 29 is mounted with a support rod 5 , the outer end of the support rod 5 is mounted with an end plate 32 , and the outer end of the traverse cylinder 4 is mounted on the end plate 32 .

[0038] The lateral cylinder 4 is fixed at both ends, with one end connected to the end plate 32 and the other end fixed to the mounting plate 29 through an L-shaped reinforcement rib to form a torsion-resistant structure. This support system can effectively offset the inertia moment generated by the lateral movement, making the installation of the lateral cylinder 4 more stable, ensuring that the cleaning lateral movement assembly runs smoothly during the left and right movement, thereby improving the accuracy and reliability of brush cleaning.

[0039] A first liquid inlet valve 21 and a first liquid discharge valve 22 are provided on the outer side of the end plate 32, and an inlet and outlet liquid joint 35 is provided on the side of the cleaning plate 7. The inlet and outlet liquid joint 35 is connected to the flow channel, and the first liquid inlet valve 21 and the first liquid discharge valve 22 are connected to the inlet and outlet liquid joint 35, thereby realizing the recycling of the cleaning liquid. When cleaning is required, the cleaning liquid enters the cleaning plate 7 through the first liquid inlet valve 21. After cleaning is completed, the waste liquid is discharged through the first liquid discharge valve 22, thereby reducing the production cost and improving the degree of automation of the cleaning process.

[0040] like Figure 4 , Figure 5 As shown, the brush cleaning mechanism 28 also includes a liquid storage tank 8, on which a second liquid inlet valve 13, an air inlet connector 16 and a second liquid level gauge 27 are provided. The second liquid level gauge 27 is installed on the side of the liquid storage tank 8 and is connected to the interior of the liquid storage tank 8. The second liquid inlet valve 13 is connected to the first liquid inlet valve 21 through a pipeline.

[0041] The liquid storage tank 8 adopts a pressure vessel structure as a storage container for the cleaning liquid. The air inlet connector 16 is connected to the compressed air source. The liquid level in the liquid storage tank 8 is monitored in real time through the second liquid level sensor 27 to ensure a stable supply of cleaning liquid. When the liquid level is insufficient, it can be replenished in time to ensure the continuous operation of the entire cleaning system.

[0042] like Figure 3 As shown, the brush cleaning mechanism 28 also includes a recovery tank 3, on which a liquid inlet pneumatic valve 25, a third liquid level sensor 26 and a negative pressure joint 43 are provided. The third liquid level sensor 26 is installed on the side of the recovery tank 3 and is connected to the inside of the recovery tank 3. The liquid inlet pneumatic valve 25 is connected to the first liquid discharge valve 22 through a pipeline.

[0043] The recovery tank 3 is used to recover the cleaned waste liquid. The negative pressure joint 43 is connected to the vacuum pump to form a suction power source, which improves the recovery efficiency of the waste liquid and reduces production costs. At the same time, the third liquid level device 26 can monitor the liquid level in the recovery tank 3 in real time to avoid waste liquid overflow.

[0044] The DMC cleaning liquid in the liquid storage tank 8 is pressed out from the liquid outlet of the liquid storage tank 8 by pressure, enters the pneumatic valve through the liquid inlet connector of the first liquid inlet valve 21, and then exits from the liquid outlet connector of the first liquid inlet valve 21, connected to the liquid inlet and outlet connector 35, and enters the cleaning tank 20 of the cleaning plate 7 through the liquid inlet and outlet connector 35. The liquid level is controlled by the first liquid level device 24. After the cleaning times are reached, it also passes through the liquid inlet and outlet connector 35 to the liquid inlet connector of the first liquid discharge valve 22, through the pneumatic valve, and from the liquid outlet connector of the first liquid discharge valve 22 to the liquid inlet pneumatic valve 25, and finally recovered to the recovery tank 3. The recovery tank 3 provides negative pressure through the negative pressure connector 43 to absorb the DMC.

[0045] Example 2

[0046] This embodiment provides a cleaning device for the liquid injection port of a battery cell 9, such as Figure 3 As shown, it includes a moving mechanism, a wiping mechanism and a brush cleaning mechanism 28. The moving mechanism includes a blocking mechanism 1, a blocking lifting cylinder 2 and a logistics line 6. The battery cell 9 is transported on the logistics line 6. The blocking lifting cylinder 2 lifts the blocking mechanism 1 to transport the battery cell 9 backward. The brush cleaning mechanism 28 is installed on the device substrate to clean the brush. The device enables the battery cell 9 to automatically clean the injection port during transportation, improves cleaning efficiency and quality, reduces manual intervention, realizes uninterrupted continuous operation, and improves the automation level of the entire production process.

[0047] like Figure 5 , Figure 6 As shown, the wiping mechanism includes a cleaning brush 10, a rotating motor 11, a brush lifting cylinder 17, a lifting guide rail 18 and a fixed block 19. The lifting guide rail 18 is installed on the device substrate, and the fixed block 19 is installed on the lifting guide rail 18. The brush lifting cylinder 17 drives the fixed block 19 to rise and fall. The rotating motor 11 is installed on the fixed block 19. The cleaning brush 10 is installed at the bottom of the rotating motor 11 to achieve the lifting and lowering adjustment of the cleaning brush 10 in the vertical direction, and the rotating motor 11 is used to achieve rotary wiping, so as to effectively clean the liquid filling port of the battery cell 9 and improve the cleaning effect.

[0048] Example 3

[0049] This embodiment provides a working method of the brush cleaning mechanism 28 as described in Embodiment 1, including:

[0050] When the battery cell 9 flows into the wiping mechanism, the blocking lifting cylinder 2 descends, the logistics line 6 stops rotating, the brush lifting cylinder 17 descends, and the rotating motor 11, driven by the fixed block 19, descends and starts to rotate to grind the liquid injection port of the battery cell 9. After cleaning, the rotating motor 11 stops rotating, the brush lifting cylinder 17 rises, the blocking lifting cylinder 2 rises, and the battery cell 9 continues to flow downward.

[0051] According to the actual grinding effect, the upper limit of the cleaning times is verified and set. When the cleaning times reach the set value, the cleaning plate 7 is pushed to the right by the lateral cylinder 4 to reach the upper limit of the cleaning times. Figure 5 The lifting cylinder 12 moves upward to drive the cleaning plate 7 to move upward, and ensures that the cleaning brush 10 is placed in the cleaning tank 20 (there is DMC cleaning liquid in the tank) for immersion and rotation cleaning. After the cleaning is completed, the lifting cylinder 12 moves downward, and the cleaning plate 7 returns to its original position under the action of the transverse cylinder 4, and the DMC liquid in the cleaning tank 20 is discharged.

[0052] The workflow adopts a timing control strategy, and the traverse cylinder 4 and the lifting cylinder 12 work together according to the preset program. The cleaning stage includes a three-step cycle: the traverse cylinder 4 drives the cleaning plate 7 to move directly under the brush during the positioning stage; the lifting cylinder 12 lifts the cleaning tank to wrap the brush during the immersion stage, and the rotary motor 11 starts at the same time; the cleaning plate 7 is reset and the drainage program is triggered during the drainage stage. This working method realizes the automatic cleaning of the brush, ensures its cleaning effect, avoids incomplete cleaning due to dirty brushes, improves the operating efficiency and reliability of the equipment, and reduces manual maintenance costs.

[0053] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
