Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a roller cleaning device. Background Technology

[0002] In lithium battery manufacturing, cleaning the rollers is a crucial step in ensuring electrode quality and production efficiency. Traditional manual wiping methods have several problems, such as frequent machine shutdowns, inconsistent cleaning results, and the potential for mechanical damage to the roller surface. Furthermore, while existing roller wiping devices have addressed these issues to some extent, they still have shortcomings. For example, some devices only use a damp cloth, which can leave liquid residue that may react with the materials, affecting product quality. Other devices tend to leave ring-shaped or S-shaped streaks on the roller surface during wiping, affecting its normal use.

[0003] To overcome these shortcomings, several improved wiping roller devices have been proposed. For example, a nonwoven fabric-impregnated wiping roller device improves cleaning efficiency by wrapping nonwoven fabric around the wiping roller, first wiping the roller surface with the wet nonwoven fabric, and then wiping it a second time with a dry nonwoven fabric. However, this device still has some limitations, such as the lack of automation in the nonwoven fabric winding and changing process, and the inability to dynamically adjust the cleaning range according to the electrode size.

[0004] Therefore, a more efficient, automated, and adaptable roller cleaning device is needed to meet the stringent requirements for roller cleaning in the lithium battery production process. Utility Model Content

[0005] The purpose of this utility model is to provide a roller cleaning device, which sets a roller surface cleaning mechanism on one side of the roller. The roller surface is dynamically wiped by the wiping cloth driven by the take-up roller and the unwind roller, thereby improving the degree of cleaning automation. In addition, the cleaning range can be adjusted by adjusting the lateral displacement of the roller cleaning mechanism to meet the wiping work of roller surfaces of different sizes, and it has strong versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a roller cleaning device, comprising:

[0008] A roller surface cleaning mechanism includes a take-up roller and an unwind roller that are parallel to each other, and a wiping cloth wound between the take-up roller and the unwind roller;

[0009] The support includes a guide rod parallel to the guide roller and a suspension rod slidably connected to the guide rod; the end of the suspension rod is connected to the end of the take-up roller and the unwind roller.

[0010] A further embodiment: the number of roller surface cleaning mechanisms is two; the two roller surface cleaning mechanisms are arranged in a staggered manner, and in the direction of the roller axis, the edges of the unwinding rollers of the two roller surface cleaning mechanisms overlap each other.

[0011] A further embodiment: the number of roller surface cleaning mechanisms is three; one roller surface cleaning mechanism is located below the middle position of the other two roller surface cleaning mechanisms, and in the direction of the roller axis, the edges of the unwinding rollers of adjacent roller surface cleaning mechanisms overlap each other.

[0012] A further option includes a spray mechanism located below the roller surface cleaning mechanism.

[0013] A further option includes a dust collection mechanism located below the roller cleaning mechanism.

[0014] A further option includes a CCD vision mechanism located below the roller cleaning mechanism.

[0015] A further embodiment: The spraying mechanism includes a spray pipe parallel to the roller, a plurality of spray nozzles spaced apart on the spray pipe, and a cleaning agent supply unit connected to the spray pipe.

[0016] A further solution: Each spray nozzle has an independent switch.

[0017] A further option: the boom is a telescopic boom.

[0018] A further embodiment: the direction of movement of the wiping roller cloth is set opposite to the direction of the tangent of the roller movement.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention features a roller surface cleaning mechanism on one side of the roller. The wiping cloth dynamically wipes the roller surface via a take-up and unwound roller, improving the automation of the cleaning process. Furthermore, the cleaning range can be adjusted by regulating the lateral displacement of the cleaning mechanism, accommodating roller surfaces of different sizes and offering high versatility. In addition, the dynamic winding design of the wiping cloth ensures that the contact surface with the roller surface remains dry, preventing the wiped roller surface from becoming excessively damp and simplifying the drying process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0027] Please see Figure 1-3 In this embodiment, a roller cleaning device includes a roller surface cleaning mechanism 1 and a support 2, wherein:

[0028] The roller surface cleaning mechanism 1 includes a take-up roller 11 and an unwind roller 12 that are parallel to each other, and a wiping cloth 13 wound between the take-up roller 11 and the unwind roller 12; the wiping cloth 13 is dynamically wiped on the roller surface of the roller 3 during the winding process by the coordinated operation of the take-up roller 11 and the unwind roller 12.

[0029] The support 2 includes a guide rod 21 parallel to the guide roller 3 and a suspension rod 22 slidably connected to the guide rod 21; the end of the suspension rod 22 is connected to the ends of the take-up roller 11 and the unwind roller 12. The suspension rod 22 can slide freely on the guide rod 21. By adjusting the horizontal displacement of the suspension rod 22, the relative position of the wiping cloth 13 and the guide roller 3 can be adjusted, thereby adjusting the cleaning range. The winding design of the wiping cloth 13 ensures that the contact surface with the roller surface remains dry, and the roller surface will not be too damp after wiping, simplifying the drying process, which only requires simple air drying.

[0030] Furthermore, there are three roller surface cleaning mechanisms 1; one roller surface cleaning mechanism 1 is located below and in the middle position of the other two roller surface cleaning mechanisms 1, and in the direction of the axis of the roller 1, the edges of the unwinding rollers 12 of adjacent roller surface cleaning mechanisms 1 overlap each other, ensuring continuous coverage of the wiping cloth 13 on the roller surface and avoiding cleaning dead corners caused by the gaps between the wiping cloths. The three roller surface cleaning mechanisms 1 are arranged vertically in a staggered manner, which on the one hand facilitates continuous coverage of adjacent wiping cloths 13 on the roller surface, and on the other hand, avoids mutual interference between the cleaning rollers.

[0031] In other embodiments, the number of roller surface cleaning mechanisms 1 can also be set to two; the two roller surface cleaning mechanisms 1 are arranged one above the other in a staggered manner, and the edges of the unwinding rollers 12 of the two roller surface cleaning mechanisms 1 overlap each other in the axial direction of the roller 1.

[0032] Furthermore, this device also includes a spraying mechanism 4 located below the roller surface cleaning mechanism 1. The spraying mechanism 4 can evenly spray liquid onto the roller surface, wetting foreign objects (such as powder, dust, sticky substances, etc.) on the roller surface. This helps to reduce the adhesion between foreign objects and the roller surface, making it easier for the foreign objects to be removed by the roller surface cleaning mechanism 1.

[0033] Furthermore, the spraying mechanism 4 includes a spray pipe 41 parallel to the roller 3, a plurality of spray nozzles 42 spaced apart on the spray pipe 41, and a cleaning agent supply unit 43 connected to the spray pipe 41. The cleaning agent supply unit 43 stores cleaning agent or water and sprays an appropriate amount onto the roller surface through the spray nozzles 42. Each spray nozzle 42 has an independent switch. Depending on the roller surface size, the spraying area can be selected to avoid unnecessary waste.

[0034] Furthermore, the device also includes a dust collection mechanism 5 located below the roller surface cleaning mechanism 1. The dust collection mechanism 5 is installed below the spraying mechanism 4 and can efficiently remove larger floating dust and powder from the roller surface, performing preliminary cleaning of the roller surface.

[0035] Furthermore, the device also includes a CCD vision mechanism 6 located below the roller surface cleaning mechanism 1. The CCD vision mechanism 6 is used to monitor the presence of foreign objects on the roller surface. If an abnormality is found, a signal is transmitted to the host computer to stop the machine for maintenance.

[0036] Furthermore, the suspension rod 22 is a telescopic rod. It is used to adjust the height of the roller surface cleaning mechanism 1, so that the wiping cloth 13 is closer to the roller surface for effective cleaning.

[0037] When this utility model is in operation, the roller surface rotation direction is as follows: Figure 2As indicated by the arrow, the roller surface moves upward. First, the dust extraction mechanism 5 removes larger floating dust, powder particles, and other foreign objects from its surface. Then, under the action of the spraying mechanism 4, the foreign objects on the roller surface are moistened. The moistened roller surface continues to move upward and comes into contact with the wiping cloth 13. The wiping cloth 13 moves in the opposite direction to the roller surface under the drive of the take-up roller 11 and the unwind roller 13, wiping away the foreign objects on the roller surface. The roller surface condition is monitored by the CCD vision mechanism 6. If the roller surface cleanliness meets the standard (based on the size and number of foreign objects detected by the CCD vision mechanism 6), the wiping stops, and preparations are made for the winding electrode process. If the roller surface cleanliness does not meet the standard, the wiping continues until the roller surface is clean. When the wiping stops, the suspension rod 22 retracts upward, moving the roller surface cleaning mechanism 1 (mainly the wiping cloth 13) away from the roller surface to avoid affecting the subsequent winding process.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
