Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, and particularly relates to a novel cleaning device for liquid injection sleeve cups. Background Art

[0002] In the process of manufacturing lithium batteries, injecting electrolyte into the battery is a very important step. During the liquid injection process, a liquid injection machine is required, and the liquid injection machine uses a liquid injection sleeve cup to inject electrolyte into the battery. During the liquid injection process, electrolyte will remain on the liquid injection sleeve cup. When the accumulated residual electrolyte on the liquid injection sleeve cup reaches a certain amount, it will affect the next liquid injection effect. Therefore, after being used for a period of time, the liquid injection sleeve cup in the liquid injection machine needs to be cleaned.

[0003] Currently, the following method is usually adopted to clean the liquid injection sleeve cup: First, a large square open cleaning tank is used and a large amount of DMC liquid is filled in the cleaning tank. Then, the liquid injection sleeve cup is driven to descend and immersed in the DMC liquid by a translation and lifting mechanism; after immersion is completed, the liquid injection sleeve cup is driven to rise by the translation and lifting mechanism to complete the cleaning action. When the above cleaning method is adopted, due to the large volume of the cleaning tank, the amount of DMC liquid used is large and the cost is high; secondly, due to the large amount of DMC liquid, the DMC liquid is easily exposed to the air for a long time, which will cause great pollution to the air in the surrounding environment; finally, when the liquid injection sleeve cup is removed after immersion, the residual DMC liquid on the liquid injection sleeve cup will drip onto other components, causing pollution and being troublesome to clean.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0038] Refer to Figures 1-5The utility model provides a novel liquid injection cup cleaning device, including a base 1 and at least one cleaning mechanism 2 arranged on the base 1, the cleaning mechanism 2 includes a first support 21 and a second support 22 arranged close to the first support 21, the first support 21 and the second support 22 are both long strips and extend in the left and right directions. Among them, the first support 21 is provided with a groove 211 which is also in the shape of a long strip and has an open top. The groove 211 is filled with DMC (DimethylCarbonat, liquid dimethyl carbonate) liquid. A plurality of injection cups (not shown in the figure) arranged in rows and spaced apart can be inserted into the groove 211 and immersed in the DMC liquid for cleaning; in addition, the second support 22 is provided with a plurality of negative pressure suction nozzles 23 corresponding to the rows of injection cups. The negative pressure suction nozzles 23 are provided with a through groove 231 for the injection cups to be inserted into. The second support 22 is provided with an air suction cavity 221 connecting the plurality of through grooves 231. Under the suction force of the air suction cavity 221, the residual liquid in the injection cup can be sucked away to ensure the dryness of the injection cup.

[0039] Therefore, when the liquid injection cups need to be cleaned, the cleaning mechanism is first driven to move forward and backward so that the first support 21 is located below the row of liquid injection cups, and then the row of liquid injection cups are driven to descend so that they extend into the groove 211 and are immersed in the DMC liquid; when the immersion is completed, the row of liquid injection cups can be driven to rise to separate from the first support 21, and then the cleaning mechanism is driven to continue to move forward and backward again so that the second support 22 is located below the row of liquid injection cups, and then the row of liquid injection cups are driven to descend so that they extend into the through groove 231 of the negative pressure suction nozzle 23, and then the residual liquid in the liquid injection cups can be sucked away under the action of suction, thereby completing the cleaning of the liquid injection cups.

[0040] Among them, by setting the groove 211 in a long strip shape, it is not only ensured that the rows of injection cups can be smoothly inserted into the groove 211 and immersed in the DMC liquid, but also the volume of the groove 211 is reduced, thereby effectively reducing the amount of DMC liquid used and reducing costs; in addition, reducing the amount of DMC liquid used can also reduce its volatilization to reduce the pollution to the air. In addition, by setting a plurality of negative pressure suction nozzles 23, when the injection cup is immersed and inserted into the negative pressure suction nozzle 23, the residual liquid in the injection cup can be sucked away under the action of suction, thereby ensuring the dryness of the injection cup and preventing the residual liquid from dripping onto other components and causing pollution, thereby ensuring the cleanliness and hygiene of the equipment.

[0041] Furthermore, a sealing ring 24 is also provided on the top of the negative pressure suction nozzle 23. Preferably, the sealing ring 24 is a sealing ring. When the injection cup is extended into the through groove 231 of the negative pressure suction nozzle 23, the sealing ring 24 can be tightly sleeved on the outer peripheral side of the injection cup to achieve a waterproof seal, thereby preventing residual liquid from splashing around under the action of suction and causing pollution, thereby ensuring that the equipment is clean and hygienic.

[0042] Preferably, the sealing ring 24 is made of EPDM rubber, which can not only undergo elastic deformation to a certain extent, but also be resistant to electrolyte corrosion, thereby increasing its service life.

[0043] In addition, in order to realize the simultaneous cleaning of multiple rows of injection cups, the cleaning mechanism 2 is also correspondingly provided with multiple groups, and the multiple groups of cleaning mechanisms 2 are arranged on the base 1 at intervals along the front-to-back direction. Among them, in order to realize the synchronous driving of the multiple groups of cleaning mechanisms 2 to move forward and backward, the base 1 is also provided with a translation mechanism 3. Specifically, the translation mechanism 3 includes a driving device 31 arranged on the base 1, two slide rails 32 arranged on the left and right sides of the base 1, and two sliding seats 33 respectively slidably arranged on the two slide rails 32. One end of the multiple groups of cleaning mechanisms 2 is connected to a sliding seat 33, and the other end is connected to the other sliding seat 33; the driving device 31 is connected to the cleaning mechanism 2 close to it. Therefore, under the action of the driving device 31, a group of cleaning mechanisms 2 can be driven to move forward and backward, and the sliding cooperation between the sliding seat 33 and the slide rail 32 can be used to drive the multiple groups of cleaning mechanisms 2 to move forward and backward at the same time.

[0044] Specifically, the cleaning mechanism 2 also includes two mounting seats 25 spaced apart from each other on the left and the left end of the first support 21 and the left end of the second support 22 are both mounted on the mounting seat 25 on the left, and are connected to the sliding seat 33 on the left through the mounting seat 25; the right end of the first support 21 and the right end of the second support 22 are both mounted on the mounting seat 25 on the right, and are connected to the sliding seat 33 on the right through the mounting seat 25, thereby realizing the connection between multiple groups of cleaning mechanisms 2 and the sliding seats 33.

[0045] In this embodiment, the driving device 31 is a cylinder, and the telescopic rod of the cylinder is connected to the second support 22 in the cleaning mechanism 2 close to it, so as to drive the cleaning mechanism 2 to move forward and backward.

[0046] Furthermore, a residual liquid collection chamber 11 is provided on the base 1, and multiple groups of cleaning mechanisms 2 are connected to the residual liquid collection chamber 11 and are located at the top of the residual liquid collection chamber 11. Therefore, when the rows of liquid injection cups are soaked and rise to separate from the first support 21, the translation mechanism 3 needs to drive the cleaning mechanism 2 to move forward and backward so that the second support 22 is located below the liquid injection cups. During the movement, the residual liquid on the liquid injection cups will fall to the bottom of the base 1 and cause pollution. To this end, the present application sets a residual liquid collection chamber 11 on the base 1, so that the dripping residual liquid can be collected to prevent it from polluting other components, and at the same time facilitate its recycling.

[0047] Further, both the left and right sides of the bottom of the residual liquid collection chamber 11 are inclined to form a diversion slope. A liquid discharge hole 111 is opened at the center of the bottom of the residual liquid collection chamber 11, and a liquid discharge nozzle 6 communicating with the liquid discharge hole 111 is provided at the center of the bottom of the base 1. Thus, when the residual liquid drips onto the bottom of the residual liquid collection chamber 11, it can slide along the slope of the diversion slope to the middle area at the bottom, and then flows out through the liquid discharge hole 111 and the liquid discharge nozzle 6 for recovery.

[0048] Further, it further includes a liquid injection joint 4 penetrating through the bottom of the base 1. A liquid injection nozzle 26 communicating with the groove 211 is provided at the bottom of the first support 21. One end of the liquid injection joint 4 is communicated with the liquid injection nozzle 26 through a pipeline, the other end of the liquid injection joint 4 is communicated with a water pump through a pipeline, and the other end of the water pump is communicated with a DMC tank. Thus, under the action of the water pump, the DMC liquid in the DMC tank can be pumped out and enter the groove 211 of the first support 21 through the pipeline. In addition, it further includes a suction joint 5 penetrating through the bottom of the base 1 and arranged near the liquid injection joint 4. A suction nozzle 27 communicating with the suction chamber is provided at the bottom of the second support 22. One end of the suction joint 5 is communicated with the suction nozzle 27 through a pipeline, the other end of the suction joint 5 is communicated with a suction pump through a pipeline, and the other end of the suction pump is communicated with a collection tank. Thus, under the action of the suction pump, the residual liquid in the liquid injection sleeve cup can be pumped out through the through groove 231, the suction chamber 221 and the pipeline in sequence and enter the collection tank.

[0049] In this embodiment, a plurality of the liquid injection joints 4 and the suction joints 5 are provided and arranged in the front - rear direction, so as to correspond to a plurality of cleaning mechanisms 2.
