Description

Technical Field

[0001] This utility model relates to the technical field of electrode processing equipment, and in particular to an online roller wiping device for roller pressing. Background Technology

[0002] Rolling is a crucial step in the battery electrode manufacturing process, typically performed after coating and before loading, and is completed by a twin-roll mill. Among the challenges, the problem of negative electrode material sticking to the rolls has always been a major issue in lithium battery production. During the rolling process, some electrode material often sticks to the rolls, which not only wastes time and reduces efficiency but also renders the electrodes unusable, resulting in economic losses.

[0003] To solve the problem of the rolling mill rolls, existing technologies use a scraper or similar mechanism to remove the coating material that sticks to the rolls. However, due to reasons such as improper scraper angle adjustment or scraper wear, it is easy to cause incomplete scraping and localized particles sticking to the rolls. Utility Model Content

[0004] The purpose of this invention is to provide an online roller cleaning device that can improve the cleaning effect of coating materials on rollers. It replaces the scraper mechanism with a laser cleaning device, which is placed below the lower roller and above the upper roller to perform laser cleaning on the rollers in real time. The protective cover protects the workers while facilitating dust collection and cleaning. By adjusting the laser energy, the coating material adhering to the rollers can be removed without damaging them.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A roller-pressing online wiping device includes a frame, in which an upper roller and a lower roller for pressing electrode sheets are provided. A laser cleaning component and a protective cover are also connected to the frame. The laser cleaning component cleans the coating material on the corresponding roller with a laser. A slit is opened on the protective cover to allow the laser to pass through. The protective cover is slidably connected to the frame in a direction parallel to the laser irradiation. One side of the protective cover covers the outside of the corresponding roller, and the sliding path of the axis of symmetry on this side is arranged radially along the corresponding roller.

[0007] By adopting the above technical solution, the protective cover protects the staff while facilitating dust collection and cleaning. The protective cover has a slit for the laser to pass through. By adjusting the laser energy, the coating on the roller can be removed without damaging the roller, reducing the waste of water or auxiliary materials such as scrapers and improving the cleaning effect.

[0008] Furthermore, a sliding drive component is connected to the outside of the protective cover to drive its sliding movement.

[0009] By adopting the above technical solution, the sliding drive component drives the protective cover to slide along the direction parallel to the laser irradiation, which makes it easy for the slit on it to always allow the laser to pass through before and after sliding. Moreover, the sliding path of the symmetrical axis of the opening side of the protective cover is set along the radial direction of the corresponding roll, which ensures that the protective cover can be adapted to rolls of different sizes and improves the versatility of the device for rolls of different outer diameters.

[0010] Furthermore, the sliding drive component includes a lead screw and several parallel guide rods. The lead screw is driven to rotate by a motor and is threadedly connected to the protective cover. The guide rods pass through the protective cover and guide its sliding.

[0011] By adopting the above technical solution, the protective cover is moved by a lead screw and guided by a guide rod, making the movement of the protective cover more precise and allowing for accurate adjustment according to the different outer diameters of the rolls.

[0012] Furthermore, the protective cover is connected to a vacuum suction pipe.

[0013] By adopting the above technical solution, it is convenient to collect dust and other impurities generated during the laser cleaning process, avoiding the spread of pollution, improving the cleanliness of the environment, and protecting the health of the staff.

[0014] Furthermore, the irradiation direction of the laser cleaning component is located on one side of the protective cover's axis of symmetry.

[0015] By adopting the above technical solution, the irradiation direction is not in the same position as the axis of symmetry of the protective cover, which facilitates the reflection of the laser inside the protective cover, improves the cleaning effect, and also facilitates laser irradiation on one side of the protective cover while connecting the sliding drive component on the other side, reducing interference between the two components.

[0016] Furthermore, the protective cover includes end plates detachably connected to both ends, with the end plates located outside the corresponding ends of the upper or lower rolls, and the protective cover is provided with slots for inserting the end plates into different positions.

[0017] By adopting the above technical solution, the end plate can be detachably connected to both ends of the protective cover, and slots at different positions are provided in the protective cover for the end plate to be inserted into different positions, which facilitates the adjustment of the end plate position according to the different lengths of the rolls, and further improves the versatility for rolls of different specifications.

[0018] Furthermore, a limiting shaft perpendicular to the end plate is connected to the outer side of the end plate. The limiting shaft slides along its own length direction and is connected to the end plate. A limiting hole adapted to the limiting shaft is provided in the protective cover.

[0019] By adopting the above technical solution, the limiting shaft is inserted into the protective cover in a direction perpendicular to the end plate, which further improves the strength of the connection between the end plate and the protective cover and prevents the end plate from falling off if the slot becomes loose.

[0020] Furthermore, the laser cleaning component includes a laser output head and a linear module that drives the laser output head to move along the axial direction of the corresponding roll.

[0021] By adopting the above technical solution, the linear module drives the laser output head to move along the axial direction of the corresponding roll, which facilitates the laser output head to clean different positions of the roll, so that it can clean back and forth between the positions of the roll that are prone to sticking, or perform positioning cleaning according to remote control or visual sensing.

[0022] In summary, this utility model has the following beneficial effects:

[0023] The frame is connected to a laser cleaning component and a protective cover. The protective cover protects the workers while facilitating dust collection and cleaning. The protective cover has a slit for the laser to pass through. The laser cleaning component cleans the coating material on the corresponding roller with the laser. By adjusting the laser energy, the coating material stuck to the roller can be removed without damaging the roller, reducing the waste of auxiliary materials such as water or scrapers and improving the cleaning effect.

[0024] The sliding drive component drives the protective cover to slide along a direction parallel to the laser irradiation, ensuring that the slits on it can always allow the laser to pass through correspondingly before and after sliding. Furthermore, the sliding path of the protective cover's opening side symmetry axis is set along the radial direction of the corresponding roll, ensuring that the protective cover can adapt to rolls of different sizes and improving the device's versatility for rolls of different outer diameters. The end plates are detachably connected to both ends of the protective cover, and slots at different positions are provided in the protective cover for the end plates to be inserted into different positions, facilitating the adjustment of the end plate position according to the different lengths of the rolls, further improving the versatility for rolls of different specifications.

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0029] A roller pressing online wiping device, such as Figure 1 and Figure 2 As shown, the machine includes a frame 1, in which an upper roll 2 and a lower roll 3 are provided for rolling the electrode sheets. Two pairs of laser cleaning components 4 and a protective cover 5 are also connected to the frame 1. The laser cleaning components 4 clean the coating material on the corresponding rolls with laser. The protective cover 5 has a slit 51 for the laser to pass through. By adjusting the laser energy of the laser cleaning components 4, the coating material adhering to the rolls can be removed without damaging the rolls.

[0030] In this embodiment, the laser cleaning component 4 includes a laser output head 41 and a linear module 42 that drives the laser output head 41 to move along the axial direction of the corresponding roll, thereby realizing the axial displacement of the laser output head 41 and facilitating the cleaning of different positions of the roll by the laser output head 41. The laser spot is rectangular or circular. In other embodiments, it is used in conjunction with visual sensing and other methods for positioning, movement and cleaning.

[0031] like Figure 1 and Figure 2 As shown, the protective cover 5 is slidably connected to the frame 1 along the direction parallel to the laser irradiation, so that the slit 51 on it can always allow the laser to pass through before and after sliding; one side of the protective cover 5 is covered outside the corresponding roll (1-2mm or less away from the outer circumference of the roll), and the sliding path of the axis of symmetry on this side is set along the radial direction of the corresponding roll, which ensures that the protective cover 5 can be adapted to rolls of different sizes, and that the protective cover 5 can always irradiate the outside of the roll with the corresponding outer diameter before and after sliding.

[0032] In this embodiment, the movement of the protective cover 5 is driven by an electric motor. In other embodiments, it can also be replaced by manual disassembly. The protective cover 5 is externally connected to a sliding drive component that drives its sliding movement. The sliding drive component includes a lead screw 52 and several parallel guide rods 53. The lead screw 52 is driven to rotate by a motor and is threadedly connected to a displacement block on the outside of the protective cover 5. The guide rods 53 pass through the displacement block on the outside of the protective cover 5 and guide the sliding movement of the protective cover 5. The motor and lead screw 52 can also be replaced by other devices that drive linear displacement, such as an electric cylinder.

[0033] like Figure 1 and Figure 2As shown, in order to further improve the versatility of rolls of different specifications, the protective cover 5 includes end plates 55 detachably connected to both ends. The end plates 55 are located outside the corresponding ends of the upper roll 2 or the lower roll 3. They are set in a trapezoidal shape to fit the flared shape of the protective cover 5 and to ensure the blocking of the corresponding ends of rolls of different lengths.

[0034] Specifically, the protective cover 5 is provided with a number of slots 56 for the end plates 55 to be inserted into at different positions, corresponding to the corresponding end positions of rolls of different lengths. The slots 56 are distributed on different inner surfaces of the protective cover 5 and can be set independently or as a whole.

[0035] To improve the stability of the connection between the end plate 55 and the slot 56, the end plate 55 includes a rotating disk 6 rotatably connected to its outer side. A limiting shaft 61 perpendicular to the end plate 55 is connected to the outside of the rotating disk 6. The limiting shaft 61 includes limiting protrusions fixedly connected at both ends, so that the limiting shaft 61 slides along its own length direction and is connected to the rotating disk 6 and cannot be disengaged from it. The outer side of the slot 56 of the protective cover 5 is provided with a limiting hole that matches the limiting protrusion. After the end plate 55 is installed, it is rotated into place by the rotating disk 6 and then the limiting shaft 61 is inserted into the side of the slot 56 at the corresponding position to achieve fixation. Only after the limiting shaft 61 is pulled out can the end plate 55 be pulled out of the slot 56.

[0036] like Figure 1 As shown, the protective cover 5 is connected to the flexible dust suction pipe 54. In this embodiment, the protective cover 5 is installed on the right side of the roll, and the roll at this installation position rolls to the left. The dust suction pipe 54 is connected to the right side of the protective cover 5. Dust enters the dust suction pipe 54 under the action of suction and its own weight. The irradiation direction of the laser cleaning component 4 is located on the left side of the axis of symmetry of the protective cover 5. The laser cleaning is on the left side, and the sliding drive component and the dust suction pipe 54 are on the right side, which facilitates cleaning and dust suction. The inner surface of the protective cover 5 can be set as a reflective surface so that the laser can be reflected between the roll and the reflective surface. The reflection path can be adjusted by the shape of the inner wall of the protective cover 5.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
