When the battery cell is incoming, the turntable 5 can be switched to the corresponding module, and then the turntable 5 is driven downward by the lifting component, so that each module is pressed onto the surface of the battery cell injection port, and the cleaning action is performed in sequence. By diversifying the cleaning steps into steps, the cleaning of the injection port can be better achieved, and the cost of manual wiping can be greatly saved.

[0050] The above is the first embodiment of a battery cell liquid injection port cleaning device provided in the embodiment of the present application. The following is the second embodiment of a battery cell liquid injection port cleaning device provided in the embodiment of the present application. For details, please refer to Figures 1 to 7 .

[0051] The battery cell filling port cleaning device in this embodiment includes: a lifting component and a turntable 5 that is rotatably arranged on the lifting component in a horizontal direction, and a detergent dripping module 6 for dripping detergent to the battery cell filling port, a wiping module 7 for cleaning the battery cell filling port, a cleaning module 8 for cleaning electrolyte crystal residues, and a negative pressure cleaning module 9 for sucking away foreign matter cleaned by the cleaning module 8 are fixed in sequence along the circumferential direction on the turntable 5.

[0052] The lifting assembly includes a slide rail 1 arranged along the vertical direction, a linear motor 2 and a slide seat 3 are arranged on the slide rail 1, the linear motor 2 is fixedly connected to the slide rail 1, the slide seat 3 is slidably connected to the slide rail 1, and the linear motor 2 is driven to connect the slide seat 3; a turntable 5 is rotatably arranged at the bottom of the slide seat 3, and a first driving motor 4 for driving the turntable 5 to rotate is arranged on the slide seat 3.

[0053] It also includes: a controller, which is electrically connected to the linear motor 2, the first drive motor 4, the detergent dripping module 6, the wiping module 7, the cleaning module 8 and the negative pressure cleaning module 9 respectively.

[0054] It should be noted that: by using a controller to uniformly control the operation of each component, automated cleaning can be achieved, which is more convenient to use and greatly improves cleaning efficiency while saving labor costs.

[0055] like Figure 2 As shown, the detergent dripping module 6 includes a detergent pipe 61 and a drip nozzle 62 arranged at the lower end of the detergent pipe 61, a valve is arranged on the drip nozzle 62, and the upper end of the detergent pipe 61 is connected to a detergent storage tank, and the detergent stored in the detergent storage tank can be DMC.

[0056] like Figure 3 As shown, the wiping module 7 includes a cleaning member and a second driving motor 71 for driving the cleaning member to rotate. Specifically, the cleaning member includes a first connecting member 73 and a cleaning head 72; the second driving motor 71 is driven to connect the first connecting member 73; the cleaning head 72 is detachably mounted on the bottom of the first connecting member 73. The first connecting member 73 is rotatably arranged on the turntable 5 through a first fixing seat 74; the cleaning head 72 is provided with a liquid absorbing component, and the material of the liquid absorbing component can be sponge, non-woven fabric, adsorption resin, etc.

[0057] like Figure 4 and Figure 5 As shown, the cleaning module 8 includes a cleaning member and a third driving motor 81 for driving the cleaning member to rotate. The bottom of the cleaning member is connected to a first blocking head 83 for closing the liquid injection port during the cleaning process through a bearing 84. Since the first blocking head 83 and the cleaning member are assembled through the bearing 84, the first blocking head 83 will not rotate during the rotation of the cleaning member. Specifically, the cleaning member includes a second connecting member 85 and a cleaning head 82; the third driving motor 81 drives and connects the second connecting member 85; the cleaning head 82 is detachably mounted on the bottom of the second connecting member 85; the first blocking head 83 is mounted at the bottom center of the second connecting member 85 through a bearing 84; the second connecting member 85 is rotatably set on the turntable 5 through a second fixing seat 86; the cleaning head 82 can be a brush cleaning head.

[0058] It can be understood that the second drive motor 71 and the third drive motor 81 are both small motors.

[0059] like Figure 6 and Figure 7 As shown, the negative pressure cleaning module 9 includes a negative pressure pipeline 91 and a negative pressure device connected to the upper end of the negative pressure pipeline 91, and a second blocking head 92 for closing the injection port during the negative pressure cleaning process is fixed to the lower end of the negative pressure pipeline 91 through a fixing plate 93. Specifically, the negative pressure device can be a vacuum pump.

[0060] It can be understood that the first blocking head 83 and the second blocking head 92 can both be rubber nails.

[0061] The fixing plate 93 is a disc-shaped structure, and a dust suction hole is opened on the fixing plate 93 ; the second blocking head 92 is located at the center of the fixing plate 93 .

[0062] During the specific implementation, the first step is to first move the detergent dripping module 6 to the top of the battery cell injection port through the turntable 5. At this time, the drip nozzle 62 is not concentric with the injection port to avoid dripping directly into the battery cell, and then a small amount of detergent is dripped into the battery cell injection port through the detergent dripping module 6; the second step is to switch the wiping module 7 to the top of the battery cell injection port through the turntable 5, and then drive the slide 3 to move downward through the linear motor 2, so that the wiping module 7 is pressed to the position of the injection port, and then drive the cleaning head 72 to rotate through the second drive motor 71, so as to clean the battery cell injection port; the third step is to switch the cleaning module 8 to the top of the battery cell injection port through the turntable 5, and then drive the slide 3 to move downward through the linear motor 2, so that the cleaning module 8 is pressed to the position of the liquid injection port. At this time, the first blocking head 83 at the bottom of the cleaning module 8 will close the liquid injection port to prevent the battery cell from being contaminated during the cleaning process. Then, the cleaning head 82 is driven to rotate by the third driving motor 81 to clean the battery cell liquid injection port and clean out the electrolyte crystal residue in the dead corner of the previous cleaning step; Step 4: Switch the negative pressure cleaning module 9 to the top of the battery cell liquid injection port through the turntable 5, and then drive the slide 3 to move downward through the linear motor 2, so that the negative pressure cleaning module 9 is pressed to the position of the liquid injection port. At this time, the second blocking head 92 will close the liquid injection port to prevent the electrolyte from being sucked out during the negative pressure cleaning process. Then, the foreign matter cleaned out by the cleaning head 82 in the previous step is sucked away by the negative pressure cleaning module 9. It should be noted that after the entire device completes a process, each module will be reset to the origin to prevent the pipeline from being entangled.

[0063] The device has an excellent cleaning effect and can save manual wiping costs. At the same time, the device can be used in a state where the battery core is not nailed, and is more convenient to use.
