Description

Technical Field

[0001] This utility model relates to the field of diaphragm processing technology, and in particular to a movable scraping device for diaphragm coating. Background Technology

[0002] A separator is a thin film used to separate the positive and negative electrodes during electrolysis to prevent direct reaction and energy loss in the electrolytic cell. In the structure of a lithium battery, the separator is one of the key internal components. The performance of the separator determines the battery's interface structure, internal resistance, etc., and directly affects the battery's capacity, cycle life, and safety performance. A high-performance separator plays an important role in improving the overall performance of the battery.

[0003] When applying adhesive to the diaphragm, the edges need to be scraped. For example, a diaphragm coating moving scraping device provided in the prior art consists of two rollers fixedly installed between two bases, arranged parallel to each other, with a support moving groove between them. The two ends of the support moving groove are fixedly connected between the two bases, and two vertically arranged supports are slidably installed inside the support moving groove. On the sides of the two supports near the upper end, away from the bases, a scraper and an edge detection sensor are installed side-by-side. In this invention, the scraper always moves with the displacement of the diaphragm substrate, preventing excessive squeezing force on the edges of the diaphragm substrate, thus avoiding uneven edge winding and ensuring the production quality of the diaphragm. The two tension rollers provide good tension to the diaphragm substrate, ensuring that the diaphragm substrate passes smoothly through the two rollers for adhesive application, thereby improving the coating effect. This device is worthy of promotion and widespread adoption.

[0004] However, after the scraping device removes the glue from both sides of the diaphragm, the glue flows along the side of the scraper blade into the inner side of the support moving groove, making it inconvenient for workers to collect and dispose of the glue, thus affecting the working environment.

[0005] Therefore, it is necessary to provide a movable scraping device for diaphragm coating to solve the above-mentioned technical problems. Utility Model Content

Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. A movable scraping device for diaphragm coating includes: a base plate 1;

[0029] Two application rollers 2 are fixedly installed on the top of the base plate 1;

[0030] Mounting frame 4 is located between the two applicator rollers 2. The top of the mounting frame 4 has grooves 5 at both ends and a mounting groove 6 at the top. The inner side of the mounting groove 6 is provided with a storage frame 7.

[0031] Two drive telescopic rods 8 are fixedly installed on the inner sides of the two slide grooves 5 respectively. A moving plate 9 is fixedly installed on the moving end of each of the two drive telescopic rods 8. A scraper 10 is provided on one side of the moving plate 9, and a detection sensor 11 is provided on one side of the scraper 10.

[0032] A collection component 12 is disposed at the bottom of the scraper 10. The collection component 12 includes a collection frame 121 and a conveying pipe 122. The collection frame 121 is disposed at the bottom of the scraper 10, and the conveying pipe 122 is fixedly installed on one side of the collection frame 121. The output end of the conveying pipe 122 is disposed at the top of the storage frame 7.

[0033] Tensioning components 3 are fixedly installed at both ends of the top of the base plate 1.

[0034] The bottom of the movable plate 9 is slidably connected to the inner side of the slide groove 5, and the detection sensor 11 is fixedly installed on the side of the movable plate 9.

[0035] The collection frame 121 is provided with mounting components 13 on both sides. The mounting components 13 include a plug plate 131, a connecting frame 132, and a plug groove 133. The plug plate 131 is fixedly installed on both sides of the collection frame 121, the connecting frame 132 is fixedly installed on the front and back of the movable plate 9, and the plug groove 133 is opened on the top of the connecting frame 132. The plug plate 131 is inserted into the inner side of the plug groove 133.

[0036] The coating roller 2 is a rotating roller with an externally fitted adhesive plate, and the rotating roller is driven to rotate by a motor;

[0037] The tensioning assembly 3 consists of a support frame, a moving groove, a slide bar, a tensioning spring, and a tensioning roller.

The tensioning spring is sleeved on the outer side of the slide bar. The two ends of the tensioning roller are slidably connected to the outer side of the slide bar and are located on the outer side of the tensioning spring. When in use, the diaphragm is pressed on the top of the tensioning roller and passes through the bottom of the coating roller 2.

[0038] The detection sensor 11 is a distance detection sensor. When in use, it can detect the distance between the scraper 10 and the edge of the diaphragm, and then adjust the scraper 10 by driving the telescopic rod 8 so that the side of the scraper 10 is always in contact with the edge of the diaphragm.

[0039] The storage box 7 is placed on the inner side of the mounting slot 6, so that it can be removed from the inner side of the mounting slot 6 for cleaning when needed.

[0040] The working principle of the movable scraping device for diaphragm coating provided by this utility model is as follows:

[0041] During use, the position of the diaphragm edge is detected by the detection sensor 11, and then the extension rod 8 is controlled to extend and retract, so that the side of the scraper 10 is always in contact with the edge of the diaphragm to scrape off the paint in the diaphragm. At this time, the scraped paint will flow down along the side of the scraper 10 until it flows to the inner side of the collection frame 121, and then be transported to the inner side of the storage frame 7 through the conveying pipe 122, so that the storage frame 7 collects the scraped paint.

[0042] Compared with related technologies, the movable scraping device for diaphragm coating provided by this utility model has the following beneficial effects:

[0043] By cooperating with the collection component 12 and the storage box 7, the collection box 121 can collect the scraped paint during use, and then transport it to the inner side of the storage box 7 through the delivery pipe 122. This makes it convenient for workers to collect and process the scraped glue, preventing the glue from flowing into other parts and keeping the working environment clean.
