Description

Technical Field

[0001] The utility model relates to the technical field of roller cleaning, in particular to a cleaning device and equipment. Background Art

[0002] In the manufacturing process of negative electrode sheets of lithium-ion batteries, water solvent is usually used, so the sheets contain a large number of polar groups, which causes the active material on the current collector to easily adhere to the roller surface when rolling the sheets, resulting in a sticking phenomenon. In severe cases, the active material coating on the current collector will fall off, causing safety hazards.

[0003] At present, when rolling the negative electrode material of the battery, scrapers and wet wiping roller devices are usually used to clean the roller surface to solve the problem of sticking to the roller. When cleaning with a scraper, since plastic scrapers are usually thicker and the blade is less sharp, it is easy to not scrape cleanly. When a stainless steel scraper is scraped closely, it is easy to damage the roller surface and form a dust source, making it difficult to completely solve the problem of sticking to the roller. When cleaning with a wet wiping roller, a spray wiping roller is generally used. The liquid detergent is easy to evaporate during the process of spraying the non-woven fabric, causing serious waste. When wiping the roller surface, the liquid of the detergent is easy to remain, causing the electrode to become damp, affecting product quality, and it is difficult for the non-woven fabric to stick to the roller surface to thoroughly clean the roller surface.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0028] The embodiment of the utility model provides a cleaning device and equipment, which can clean the adhered objects on the roller surface without damaging the roller surface.

[0029] like Figures 1 to 3 As shown, in the first embodiment of the utility model, the cleaning device 100 includes: a spray assembly 110, a transmission assembly 120 and a drive assembly 130. The spray assembly 110 can spray a granular cleaning medium 170 onto the roller surface. The spray assembly 110 includes at least one movable spray head 111 and at least one dust box 112. The spray head 111 can spray the cleaning medium 170. The dust box 112 is arranged around the spray head 111 and can apply an adsorption force to the roller surface. The spray assembly 110 is arranged on the transmission assembly 120. The drive assembly 130 is connected to the transmission assembly 120. The drive assembly 130 can drive the transmission assembly 120 to drive the spray assembly 110 to reciprocate along the axial direction of the roller 300.

[0030] In the first embodiment of the utility model, the driving assembly 130 can drive the spray assembly 110 to aim at the roller surface of the roller 300, and the spray head 111 of the spray assembly 110 can spray the granular cleaning medium 170 to the roller surface to bombard the adherents on the roller surface at high speed, and at the same time, the cleaning efficiency of the spray head 111 is ensured by adjusting the angle of the spray head 111 relative to the roller surface. While the roller 300 rotates, the spray assembly 110 is controlled to spray the cleaning medium 170 to the roller surface, so that the spray assembly 110 can clean the outer peripheral surface of the roller 300, and by controlling the spray assembly 110 to reciprocate along the axial direction of the roller 300, the spray assembly 110 can fully clean the roller 300.

[0031] like Figures 1 to 3 As shown, in the first embodiment of the utility model, a dust box 112 is provided around the nozzle 111. When the nozzle 111 sprays the cleaning medium 170 onto the roller surface, the dust box 112 can absorb the adhered matter and the cleaning medium 170 falling off the roller surface, collect and clean the impurities 180 after cleaning, and ensure that the roller 300 is clean after cleaning.

[0032] In the first embodiment of the utility model, the number of the nozzle 111 and the dust box 112 can be one or more, and a plurality of dust boxes 112 can be arranged around the nozzle 111 to absorb impurities 180 generated during the cleaning process, or the nozzle 111 can be arranged in the dust box 112, that is, the dust box 112 is covered on the nozzle 111, and the opening of the dust box 112 faces the roller surface, so that the nozzle 111 can spray the cleaning medium 170 onto the roller surface. When the nozzle 111 sprays the cleaning medium 170 onto the roller surface, the dust box 112 generates an adsorption force around the nozzle 111 to absorb the impurities 180 generated during the cleaning process.

[0033] Optionally, the cleaning medium 170 in the embodiment of the utility model includes dry ice or other solid substances that are volatile at room temperature. By making the dry ice into fine particles, when the nozzle 111 sprays the dry ice at high speed onto the roller surface, the adherents on the roller surface can be bombarded by a large number of fine particles at high speed, so that the adherents can be shaken off from the roller surface, and the dust box 112 can absorb the detached adherents and the sprayed dry ice particles to achieve cleaning of the roller surface.

[0034] By using solid substances that are volatile at room temperature, such as dry ice, as the cleaning medium 170, it is possible to avoid damage to the roller 300 or the pole piece by conventional cleaning methods, such as easily scratching the roller surface when cleaning the roller surface with a scraper, and easily leaving residual liquid when cleaning the roller surface with a liquid medium, causing the pole piece to become damp. The cleaning device 100 of the utility model uses dry ice particles to clean the adhesion on the roller surface, thereby achieving efficient cleaning while avoiding the defects of conventional cleaning methods.

[0035] The spray assembly 110 of the cleaning device 100 of the embodiment of the utility model can spray a granular cleaning medium 170 onto the roller surface of the roller 300. The cleaning medium 170 bombards the local adhesion of the roller surface at high speed, so that the adhesion of the roller surface can be shaken off and peeled off, and at the same time, the problem of the electrode being damp due to the residue of the liquid cleaning medium can be avoided. By adjusting the angle of the nozzle 111, the spray assembly 110 can be compatible with rollers 300 of different sizes. The drive assembly 130 can drive the spray assembly 110 to move along the axial direction of the roller 300 through the transmission assembly 120, so that the spray assembly 110 can move from one end of the roller 300 to the other end. During the movement of the spray assembly 110, the rotation speed of the roller 300 is controlled to match the spray cleaning speed of the spray assembly 110, so as to achieve comprehensive cleaning of the roller surface of the roller 300.

[0036] Optionally, the transmission assembly 120 includes a transmission rod 121 , both ends of which extend along the axial direction of the roller 300 , the transmission rod 121 is transmission-connected to the driving assembly 130 , and the injection assembly 110 is slidably disposed on the transmission rod 121 .

[0037] In the first embodiment of the utility model, the transmission rod 121 is a screw rod. When the driving assembly 130 drives the screw rod to rotate, the rotating screw rod drives the spray assembly 110 to reciprocate along the axial direction of the screw rod. By changing the rotation direction of the screw rod, the movement direction of the spray assembly 110 can be adjusted. Since both ends of the transmission rod 121 extend along the axial direction of the roller 300, that is, the transmission rod 121 is arranged parallel to the roller 300, the spray assembly 110 can reciprocate along the axial direction of the roller 300, so that the spray assembly 110 can achieve comprehensive cleaning of the roller surface of the roller 300 through reciprocating motion.

[0038] Furthermore, the transmission assembly 120 also includes a guide rod 122 and a slider 123. The two ends of the guide rod 122 extend along the axial direction of the roller 300 and are arranged on one side of the transmission rod 121. The transmission rod 121 and the guide rod 122 are passed through the slider 123. When the transmission rod 121 rotates, it can drive the slider 123 to reciprocate along the axial direction of the roller 300. The injection assembly 110 is connected to the slider 123.

[0039] In the first embodiment of the present invention, the guide rod 122 is arranged in parallel with the transmission rod 121, and both the guide rod 122 and the transmission rod 121 are penetrated through the slider 123, and the transmission rod 121 and the slider 123 are connected by a threaded structure, so that when the transmission rod 121 rotates, the slider 123 can reciprocate along the axial direction of the transmission rod 121. The guide rod 122 is used to fix the slider 123 to prevent the slider 123 from deflecting when reciprocating on the transmission rod 121, thereby ensuring the stability of the injection assembly 110.

[0040] Optionally, the injection assembly 110 is movably connected to the slider 123, and the injection assembly 110 can move closer to or farther away from the roller surface of the roller 300 relative to the slider 123, or the injection assembly 110 can rotate relative to the slider 123 to adjust the angle relative to the roller surface of the roller 300.

[0041] In the first embodiment of the present invention, the dust box 112 of the spray assembly 110 is connected to the slider 123 via a movable connection member, and the movable connection member can be a guide rail or a rotating shaft structure. When the dust box 112 is slidably connected to the slider 123 via the guide rail, the dust box 112 can slide relative to the slider 123 to get closer to or away from the roller surface; when the dust box 112 is rotatably connected to the slider 123 via the rotating shaft, the dust box 112 can rotate relative to the slider 123 to adjust the angle relative to the roller surface of the roller 300.

[0042] like Figure 3 As shown, optionally, the driving assembly 130 includes a first driving member 131, which is in driving connection with the transmission rod 121, and the first driving member 131 can drive the transmission rod 121 to rotate to drive the injection assembly 110 to reciprocate along the axial direction of the roller 300.

[0043] The first driving member 131 in the first embodiment of the utility model includes a driving motor. The combination of the transmission rod 121 and the slider 123 can also be replaced by a ball screw. By arranging the injection assembly 110 on the ball screw, the driving motor can drive the injection assembly 110 to reciprocate along the axial direction of the roller 300 by driving the ball screw to rotate.

[0044] Optionally, the cleaning device 100 further includes a limiting component, which is disposed on the periphery of the spraying component 110 , and the limiting component can limit the spraying component 110 so that the spraying component 110 is spaced apart from the roller surface.

[0045] like Figures 1 to 3 As shown, the shape of the end of the dust box 112 facing the roller surface is an arc shape that matches the roller surface, so as to ensure that the dust box 112 can absorb the impurities 180 generated during the cleaning process to the maximum extent. When the nozzle 111 sprays the cleaning medium 170 onto the roller surface of the roller 300, the cleaning efficiency of the nozzle 111 on the roller surface can be adjusted by controlling the angle of the nozzle 111 relative to the roller surface and the distance of the nozzle 111 relative to the roller surface. During the adjustment process, the spray assembly 110 needs to be limited to prevent the nozzle 111 from colliding with the roller surface or the dust box 112 from scratching the roller surface.

[0046] Optionally, the dust box 112 is movably connected to the slider 123 , and the dust box 112 can move away from or close to the end surface of the roller 300 relative to the slider 123 .

[0047] Figure 41 is a schematic diagram of the structure of the second embodiment of the cleaning device 100 of the present invention. Part of the structure of the second embodiment is the same as that of the first embodiment, and the differences between the two will be described below, and the similarities will not be described in detail.

[0048] like Figure 4 As shown, in the second embodiment of the utility model, the limiting assembly includes at least one detector 150, which is arranged at the end of the injection assembly 110 close to the roller surface. The detector 150 can detect the distance between the injection assembly 110 and the roller surface and control the interval between the injection assembly 110 and the roller surface.

[0049] Furthermore, the detector 150 includes at least one sensor and a processor, and the sensor and the processor are communicatively connected. The sensor may be a laser sensor, an infrared sensor, an ultrasonic sensor, a temperature sensor, a visual sensor or a ranging radar, etc. The sensor can detect the distance between the injection assembly 110 and the roller surface of the roller 300 and generate ranging information. The processor can control the angle of the nozzle 111 relative to the roller surface and the distance between the dust box 112 and the roller surface according to the ranging information to prevent the nozzle 111 from colliding with the roller surface or the dust box 112 from scratching the roller surface.

[0050] The detector 150 can also detect the surface temperature of the roller 300 after cleaning and whether there is any residual adhesive on the roller surface of the roller 300 through the sensor, and generate corresponding temperature information and repeated cleaning information. The temperature information is the surface temperature of the roller 300 after cleaning, and the repeated cleaning information is to clean the area on the roller surface where the adhesive remains again.

Part of the structure of the third embodiment is the same as that of the first embodiment, and the differences between the two will be described below, and the similarities will not be described in detail.

A stopper is provided on the side of the stopper 160 facing the roller surface, and the stopper is opposite to the opening of the dust box 112. When the dust box 112 moves toward the roller surface of the roller 300, the stopper can block the dust box 112 to prevent the nozzle 111 from colliding with the roller surface or the dust box 112 from scratching the roller surface.

[0054] Optionally, the driving component 130 also includes a second driving member 132 and a dust collection duct 133.

[0055] The second driving member 132 includes a fan, which can drive the dust box 112 to generate adsorption force on the roller surface, so that the dust box 112 can collect impurities 180 generated after the spray assembly 110 cleans the roller surface, and transport the impurities 180 to the outside through the dust pipe 133.

[0056] Furthermore, a filter is provided in the second driving member 132 or the dust collection pipe 133 to filter the impurities 180 collected by the dust collection box 112 during the adsorption process.
