Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0030] In the field of battery manufacturing technology, due to the stickiness of dust on the surface of the pole piece, dust, adhesives, etc. are easily adhered to the roller during rolling, affecting the shape and position accuracy of the roller surface, or causing secondary pollution to the pole piece. In order to avoid the influence of dust, a metal scraper is usually used in the prior art to scrape off the dust adhering to the roller surface, but in the process of scraping off the dust on the roller surface, the metal scraper is likely to scratch the surface of the roller, and when the metal scraper is used to scrape off the surface of the roller, when the coating on the surface of the roller becomes thinner, it is easy to cause the hardness of the roller surface to change, shortening the service life of the roller. At the same time, when the metal scraper is scraping off the dust on the roller surface, it is easy for metal dust to fall on the pole piece, causing the pole piece to puncture the diaphragm due to lithium deposition, causing the battery to short-circuit and catch fire, or even cause the battery to explode.
[0031] The embodiment of the utility model provides a roller surface cleaning device, which can melt or gasify the dust on the surface of the pressure roller through the high temperature of the laser without affecting the product process requirements, which is beneficial to reduce the risk of dust falling during the production process and increase the service life of the pressure roller, while also improving the production safety of the equipment.
[0032] like Figures 1 to 5 As shown, an embodiment of the utility model provides a roller surface cleaning device, which is used to clean the surface of a pressure roller 100. The roller surface cleaning device includes: a first cleaning component 200 and a second cleaning component 300. The first cleaning component 200 is arranged on one side of the pressure roller 100.

The laser cleaning part 210 can emit a laser and irradiate the surface of the pressure roller 100 so that the dust on the surface of the pressure roller 100 is separated from the surface of the pressure roller 100 under high temperature. The second cleaning component 300 is arranged on the other side of the pressure roller 100 and is arranged opposite to the first cleaning component 200. The second cleaning component 300 can clean and collect dust on the surface of the pressure roller 100.
[0033] The technical solution of the utility model adopts the provision of a first cleaning component 200. The laser cleaning part 210 in the first cleaning component 200 can emit a laser, and the dust on the surface of the pressure roller 100 melts or vaporizes under the high temperature state of laser irradiation, so that the dust can be separated from the surface of the pressure roller 100 under the thermal effect, which is conducive to reducing the risk of dust falling during the production process without affecting the product process requirements, and improving the service life of the pressure roller 100, and at the same time can also improve the safety of equipment production. In the technical solution of the utility model, by providing a second cleaning component 300, the second cleaning component 300 can assist in removing the floating powder remaining after the laser cleaning of the first cleaning component 200, which is conducive to improving the removal effect of the dust on the surface of the pressure roller 100.
[0034] In the embodiment of the utility model, the pole piece 500 is squeezed by two rollers 100 arranged in parallel up and down to achieve the compaction of the surface material of the pole piece 500. In the process of squeezing the pole piece 500, some dust on the surface of the pole piece 500 will adhere to the surface of the roller 100. When the two rollers 100 rotate to the laser irradiation area of the laser cleaning unit 210, the laser emitted by the laser cleaning unit 210 irradiates the surface of the roller 100, and the surface material on the roller 100 can be melted or gasified by the high temperature of the laser without affecting the product process requirements. The adhesive of the adhered particles fails due to the high temperature, and the adhesive force is eliminated, so that the adhered objects are easily separated from the surface of the roller 100, so as to remove the dust adhered to the surface of the roller 100. In the process of cleaning the surface of the roller 100 by laser, the roller 100 is not directly contacted, so the risk of metal dust falling on the surface of the roller 100 is reduced, which is conducive to improving safety.

The technical solution of the utility model adopts the provision of the first collecting portion 220, and the first collecting portion 220 can clean and collect the dust separated from the surface of the pressure roller 100, and avoid the dust from adhering to the surface of the pressure roller 100, which is conducive to improving the cleaning effect, reducing the risk of dust falling during the production process, and increasing the service life of the pressure roller 100, and at the same time can also improve the production safety of the equipment.
