Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device with a coated diaphragm wound. Background Technology

[0002] The separator is one of the four essential materials in lithium-ion batteries. It effectively prevents short circuits caused by direct contact between the positive and negative electrodes. The performance of the separator determines the battery's internal resistance and interface structure, directly affecting the battery's electrochemical performance and safety.

[0003] Currently, the mainstream commercially available separators are polyolefin microporous membranes. Because these polyolefin microporous membranes have low melting points, they can shrink or even melt when the battery temperature rises, potentially leading to a short circuit, fire, or even explosion. Furthermore, these polyolefin separators have insufficient wettability with the electrolyte, resulting in poor electrolyte absorption and retention capacity, thus affecting the battery's charge and discharge performance.

[0004] In the production process of energy storage devices such as lithium-ion batteries, the separator is a key component, and its surface cleanliness and electrostatic state directly affect the battery's performance, safety, and cycle life. In traditional processes, the coated separator is often cleaned manually by wiping or simply blowing before winding. This method has several drawbacks: firstly, the cleaning efficiency is low, making it difficult to completely remove the tiny dust particles adhering to the separator surface; secondly, manual operation can easily introduce new sources of pollution, increasing the risk of secondary contamination. Therefore, a cleaning device for coated separator winding is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device with a coated diaphragm winding to solve the problems mentioned in the background art.

[0030] Example

[0031] Please see Figure 1-5 This utility model provides a technical solution: a cleaning device for coating and winding a diaphragm, including a diaphragm body 1 suitable for coating processing, with support frames 4 on both sides of the diaphragm body 1, and a rotating roller 3 rotatably connected to one side of the support frame 4 via a bearing. After the diaphragm body 1 is coated with alumina, the heat resistance and electrolyte wettability of the diaphragm body 1 can be improved to a certain extent. However, due to the poor adhesion between the alumina coating and the polyolefin microporous membrane, the alumina coating is easy to fall off. The diaphragm body 1 is a polymer material, and its internal molecular chains precipitate white "dust" on the surface of the diaphragm body 1 due to different cooling rates during the drying process. During the winding process of the diaphragm body 1, these precipitated white "dust" may puncture the diaphragm body 1, causing a safety hazard of short circuit between the positive and negative electrodes.

[0032] A fixing frame 8 is provided on one side of the diaphragm body 1. Two suction nozzles 5, a brush plate 6 and an antistatic bar 7 are respectively installed on one side of the fixing frame 8. A collection box 9 is installed on one side of the fixing frame 8. The suction nozzle 5 has an air suction groove inside, which is connected to the hose 14.

[0033] The fixing frame 8 is provided with a connecting component 2 for disassembling and assembling the brush plate 6 on one side. This device is located between the automatic optical inspection and winding and turning mechanism in the diaphragm body 1 production line.

[0034] The connecting component 2 includes a limiting frame 21 and a connecting rod 22. The limiting frame 21 has a limiting groove 25 and a sliding groove 27 on its inner side. The connecting rod 22 has a locking groove 24 on one side. A sliding plate 29 is slidably connected to the inner side of the sliding groove 27. A locking rod 23 is fixed to one side of the sliding plate 29. Pulling the pull rod 26 to one side causes the pull rod 26 to drive the sliding plate 29 to slide inside the sliding groove 27. At this time, the sliding plate 29 drives the locking rod 23 away from the inner side of the locking groove 24. Several brush bristles are fixedly inserted into one side of the two brush plates 6. One side of the brush bristles is slidably connected to one side of the diaphragm body 1. Pulling the brush plate 6 downwards allows the worn brush plate 6 to be removed. Then, a new brush plate 6 is taken and the connecting rod 22 at the top of the brush plate 6 is aligned with the limiting groove 25.

[0035] A pull rod 26 is fixed to the side of the slide plate 29 away from the locking rod 23. The outer side of the pull rod 26 passes through one side of the limiting frame 21. A spring 28 is sleeved on the outer side of the pull rod 26. The two sides of the spring 28 are respectively connected to the slide groove 27 and one side of the slide plate 29. One side of the limiting frame 21 is fixed to one side of the fixing frame 8. One side of the connecting rod 22 is fixed to one side of the brush plate 6. Pulling the pull rod 26 to one side compresses the spring 28 on the slide plate 29 and continues to insert the connecting rod 22 into the bottom of the limiting groove 25. Then, the pulling force of the pull rod 26 is released. At this time, under the elastic force of the spring 28, the locking rod 23 is pushed into the inner side of the locking groove 24.

[0036] The suction nozzle 5 and the antistatic rod 7 are located on both sides of the brush plate 6. The two brush plates 6 are located on both sides of the diaphragm body 1. The antistatic rod 7 is 2 cm away from the diaphragm body 1. A door 12 is bolted to one side of the collection box 9. A baffle 11 is bolted to the top of the collection box 9. A filter screen 13 inserted into the inside of the collection box 9 is fixed at the bottom of the baffle 11. Sealing rings are glued to one side of the baffle 11 and the door 12 to prevent air and dust leakage. A centrifugal fan 10 is connected to the air outlet of the collection box 9. A hose 14 is fixed to one end of the collection box 9. The air inlet of the hose 14 is connected to the air outlet of the suction nozzle 5. The suction force generated by the centrifugal fan 10 draws the dust into the collection box 9 through the suction nozzle 5, ensuring that the dust is removed quickly and efficiently, avoiding dust residue on the surface of the diaphragm body 1 and possible secondary pollution.

[0037] The model number of the antistatic bar 7 is Q5008B.

[0038] The model of centrifugal fan 10 is CY180. Since the internal structure and operating principle of the antistatic bar 7 and centrifugal fan 10 of this model are existing technologies, they will not be described in detail here.

[0039] Working principle: When the diaphragm body 1 is conveyed from left to right under the action of the rotating roller 3, the centrifugal fan 10 is started, and the diaphragm body 1 comes into contact with the bristles on one side of the brush plate 6. The bristles brush off the dust on the surface of the diaphragm body 1.

[0040] When the centrifugal fan 10 generates suction at the air inlet, the suction is transmitted to the inside of the hose 14 through the collection box 9, so that the suction nozzle 5 connected to the hose 14 generates suction. The suction nozzle 5 sucks the dust brushed off by the brush plate 6 into the inside of the suction nozzle 5, and under the action of the hose 14, the dust is transported to the inside of the collection box 9. Under the blocking effect of the filter screen 13, the dust is collected inside the collection box 9, avoiding secondary pollution caused by residual powder on the surface of the diaphragm body 1.

[0041] The diaphragm body 1, after being brushed to remove powder, passes under the antistatic bar 7. The antistatic bar 7 removes static electricity from the surface of the diaphragm body 1. Then, the diaphragm body 1 is wound up under the action of the winding and turning mechanism (not shown in the figure).

[0042] When the bristles on the surface of the brush plate 6 are worn, simply pull the lever 26 to one side, causing the lever 26 to slide the slide plate 29 inside the groove 27. At this time, the slide plate 29 will cause the locking rod 23 to move away from the inside of the locking groove 24. Then pull the brush plate 6 down to remove the worn brush plate 6. Then take a new brush plate 6, align the connecting rod 22 at the top of the brush plate 6 with the limiting groove 25, and pull the lever 26 to one side. At this time, the slide plate 29 will compress the spring 28 and continue to insert the connecting rod 22 into the bottom of the limiting groove 25. Then release the pulling force of the lever 26. At this time, under the elastic force of the spring 28, the locking rod 23 will be pushed into the inside of the locking groove 24. At this time, the replacement of the brush plate 6 is completed.

[0043] In summary, the contact between the brush bristles and the diaphragm body 1 effectively removes dust from its surface. Simultaneously, the suction generated by the centrifugal fan 10 draws the dust into the collection box 9 through the nozzle 5, ensuring that the dust is removed quickly and efficiently, avoiding dust residue on the surface of the diaphragm body 1 and potential secondary pollution. The antistatic bar 7 removes static electricity from the surface of the diaphragm body 1. The entire cleaning and antistatic process is automated, requiring no manual intervention, which greatly improves production efficiency, reduces labor costs, and also reduces errors and safety issues that may arise from human operation.

[0044] By pulling the lever 26, the slide plate 29 slides and drives the locking lever 23 away from the locking groove 24, so that the brush plate 6 can be easily removed from the limit frame 21. This greatly simplifies the replacement process of the brush plate 6, reduces the time and labor required for replacement, and allows equipment maintenance personnel to replace worn brush plates 6 more quickly, thereby reducing equipment downtime and improving overall production efficiency.
