Description

Technical Field

[0001] The utility model relates to the technical field of laser dust removal equipment, in particular to a roller surface laser mobile dust removal equipment. Background Art

[0002] In the field of battery manufacturing technology, pole pieces are generally loaded by rolling rollers (also called nip rollers). Due to the stickiness of dust on the surface of the pole pieces, the dust easily adheres to the rollers during rolling, affecting the positioning accuracy of the roller surface or causing secondary contamination to the pole pieces.

[0003] To mitigate the effects of dust, a device is now available on the market that uses lasers to remove dust from the roller surface. Laser light is irradiated onto the roller surface, ablating and vaporizing the dust. The dust and gas are then removed through a dust hood, effectively removing dust from the roller surface. However, because rollers are often large, a single laser dust removal pass is insufficient to cover the entire roller surface. Therefore, the laser must be moved via a transverse mechanism, employing multiple, intermittent dust removal operations to achieve full coverage. However, this method cannot continuously move the laser during dust removal, requiring it to complete dust removal in one area before moving to the next. This long laser transverse movement time makes laser dust removal inefficient for high-speed production. Furthermore, the laser dust removal speed is slower than the speed of the roller sticking. Therefore, while maintaining effective dust removal, it is necessary to expand the single dust removal pass and reduce the number of laser transverse passes to increase speed. This necessitates a larger dust hood, which, however, requires a high-powered dust collector to meet these requirements. This results in poor airflow uniformity, low wind speed, high flow rate, high energy consumption, and high cost. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0036] See also Figures 1 to 9This embodiment provides a roller surface laser mobile dust removal device 200, which includes: a linear motion module 1, a laser component 2 and a dust removal component 3 connected to the moving end of the linear motion module 1; the dust removal component 3 includes a dust removal cover 31, the laser component 2 includes a beam movement control unit 22, the beam movement control unit 22 controls the swing amplitude of the laser beam emitted by the laser component 2 to always be located within the dust removal cover 31, and the laser component 2 and the dust removal cover 31 are controlled by the linear motion module 1 to move back and forth synchronously. That is, in the roller surface laser mobile dust removal equipment 200 of the present embodiment, the dust removal component 3 only removes dust within the laser beam scanning width range of the laser component 2 that is currently performing regional dust removal. When the laser component 2 moves, the dust removal component 3 is synchronously controlled by the linear drive module 1 to move, so that the laser component 2 and the dust removal component 3 always maintain synchronous linear movement, thereby keeping the moving path of the laser beam controlled beam movement control unit 22 of the laser component 2 always located inside the dust removal cover 31, so that the dust removal cover 31 always only performs dust removal on the current laser scanning width range, and there is no need to perform large-scale dust removal on the entire larger area of the roller surface. Compared with the existing equipment that uses a large wind hood for dust removal, its dust removal cover 31 is smaller in size, so the power of its blowing unit and suction unit can be smaller, corresponding to smaller power consumption, and its wind field uniformity is also better. In addition, compared with the existing large wind hood dust removal equipment, the laser component 2 removes dust according to block areas. After completing the dust removal of the current block area, it is controlled by the linear drive module 1 to move once to carry out dust removal of the next adjacent block area. It does not need to control the laser component 2 to move back and forth continuously in the large wind hood like the existing large wind hood dust removal equipment. It reduces the number of lateral movements of the laser component 2, so its dust removal efficiency is also significantly improved.

[0037] Please refer again Figure 7 The dust cover 31 has an opening 310 at its front end. The edge of this opening 310 is provided with a contoured edge 311 that corresponds to the roller surface being dusted. In this embodiment, the roller surface of the roller 100 being dusted is cylindrical. Therefore, the contoured edge 311 has straight lines on its top and bottom edges and arc-shaped edges on its front and back sides. When the dust cover 31 is close to the roller surface of the roller 100, the contoured edge 311 fits snugly against the roller surface. In other embodiments, the contoured edge 311 may be configured to correspond to the shape of the dust removal surface of the object being dusted.

[0038] Furthermore, the dust removal assembly 3 also includes an air blowing unit 32 and an air suction unit 33 connected to the dust removal cover 31. The air blowing unit 32 and the air suction unit 33 are respectively arranged on the side walls of the cavity of the dust removal cover 31. In other words, the air blowing unit 32 and the air suction unit 33 are both connected to the cavity of the dust removal cover 31, and the air blowing unit 32 and the air suction unit 33 are arranged relative to each other to form a one-way airflow in the cavity, thereby quickly removing the dust vaporized by laser ablation from the roller surface.

[0039] In this embodiment, the blowing unit 32 is an air supply device with linear air outlets such as an air knife, and the linear air outlets act on the roller surface. The suction unit 33 is an air suction device such as an air pump, and only the air pipe connected to the air pump is shown in the figure.

[0040] The dust removal assembly 3 further includes at least two sets of rollers (not shown), which are respectively arranged on the upper and lower sides of the contoured edge 311. The first set of rollers is arranged on the upper side of the contoured edge 311, and the second set of rollers is arranged on the lower side of the contoured edge 311. When the dust removal assembly 3 approaches the roller surface of the roller 100, the roller 100 needs to rotate to achieve dust removal in multiple radial block areas. In order to prevent the roller surface from being scratched by the contoured edge 311 of the dust cover 31, the rollers are provided to prevent the two from contacting and scratching the roller surface. During dust removal, the rollers abut against the roller surface of the roller 100.

[0041] Please refer again Figure 2 The linear drive module 1 and the dust removal component 3 are also provided with a dust cover transverse drive module 5. The movable end of the dust cover transverse drive module 5 is connected to the dust removal component 3, specifically connected to the bottom of the dust cover 31. The movable end of the linear moving module 1 is also connected to the dust cover transverse drive module 5, that is, the linear moving module 1 can synchronously drive the laser component 2 and the dust cover transverse drive module 5 to move back and forth, and the dust removal component 3 is connected to the movable end of the dust cover transverse drive module 5, so that the dust removal component 3 and the linear drive module 1 move synchronously in the same direction. Among them, the moving direction of the dust cover transverse drive module 5 is the same as that of the linear drive module 1. In this embodiment, the size of the dust cover 31 can be made smaller, and the dust cover 31 only needs to perform dust removal on the area where the laser beam emitted by the laser component 2 is acting. The specific dust removal process is that the linear drive module 1 drives the laser assembly 2 and the dust removal assembly 3 to move once and then stops, and then starts the laser assembly 2 to emit laser, and synchronously starts the dust removal hood transverse movement drive module 5, so that the dust removal hood 31 always follows the movement of the laser beam. Therefore, in this embodiment, the size of the dust removal hood 31 can be made smaller, so that the blowing unit 32 and the suction unit 33 have smaller power, better airflow stability, and better dust removal effect.

[0042] See also Figure 5The dust cover transverse movement drive module 5 includes: a linear guide rail assembly 51, a connecting plate 52 connected to the linear guide rail assembly 51, and a servo motor 53 that drives the connecting plate 52 to move back and forth along the linear guide rail assembly 51.

[0043] Please refer again Figure 2 and Figure 3 A drive member 6 is also provided between the dust removal assembly 3 and the dust cover transverse drive module 5. The movable end of the drive member 6 is connected to the dust removal hood 31, and the driving direction of the drive member 6 is perpendicular to the moving direction of the dust cover transverse drive module 5. The moving direction of the dust cover transverse drive module 5 is the same as that of the linear drive module 1. Assuming that the linear drive module 1 drives the laser assembly 2 and the dust removal assembly 3 to move synchronously along the X direction, the drive member 6 can drive the dust removal assembly 3 to move along the Y direction relative to the laser assembly 2. The X and Y directions are the X-axis and Y-axis directions of the Cartesian coordinate system. Because the diameter of the roller 100 and the thickness of the dust on the roller surface will affect the laser focal length of the laser assembly 2, the drive member 6 is provided between the dust removal assembly 3 and the linear drive module 1. Before dust removal begins, the drive member 6 drives the dust removal assembly 3 away from the roller surface of the roller 100. When dust removal begins, the drive member 6 drives the dust removal assembly 3 closer to the roller surface.

[0044] The laser assembly 2 includes a laser generator 21 and a beam output control unit, including a beam movement control unit 22, for controlling the scanning movement of the laser beam emitted by the laser generator 21. When removing dust from a single block-shaped area, the laser generator 21 is stationary, and the beam movement control unit 22 controls the laser beam to scan within a certain width, thereby completing the dust removal of the block-shaped area. During this process, the scanning width of the laser beam is always located within the dust removal cover 31, so the dust removal cover 31 can be small in size, and the laser generator 21 does not need to continuously reciprocate over a long stroke. In this embodiment, the beam movement control unit 22 includes a galvanometer and a field lens.

[0045] Please refer again Figure 6 The linear drive module 1 includes: a drive module body 11 and a left adjustment plate 13 and a right adjustment plate 14 connected to the two ends of the drive module body 11 in the longitudinal direction, and the left adjustment plate 13 and the right adjustment plate 14 are both provided with waist-shaped holes. A movable plate 12 is provided at the movable end of the drive module body 11, and the drive module body 11 includes a connecting seat and a screw assembly and a drive motor connected to the connecting seat. The linear drive module 1 is supported or connected to the machine base or support frame, and the left adjustment plate 13 and the right adjustment plate 14 are connected to the machine base or support frame by bolts, and the bolts are passed through the waist-shaped holes. According to the focal length of the laser assembly 2 and the roller 100, the bolts are adjusted so that the roller surface laser mobile dust removal equipment 200 is adjusted to a suitable distance position from the roller 100.

[0046] Please refer again Figure 7 In this embodiment, in order to make the laser assembly 2 compatible with the roller surface dust treatment of more rollers 100 or fine-tune the focal length of the laser beam, a focusing screw assembly 4 is further provided between the laser assembly 2 and the linear drive module 1. The focusing screw assembly 4 is connected to the moving end of the linear drive module 1, and the moving end of the focusing screw assembly 4 is connected to the laser assembly 2. The adjustment direction of the focusing screw assembly 4 is perpendicular to the moving direction of the linear drive module 1, that is, the focusing screw assembly 4 is used to adjust the distance between the laser assembly 2 and the roller 100 to adjust the laser focal length. For roller surfaces of rollers 100 with different diameters, the roller surface laser scanning of the current roller 100 can be compatible by fine-tuning the focusing screw assembly 4.

[0047] Specifically, the focusing screw assembly 4 includes: a mounting plate 41, two guide rails 42 connected to the surface of the mounting plate 41, a slider 43 slidably connected to the guide rails 42, and a screw module that drives the slider 43 to move along the guide rails 42. The screw module includes: an articulated seat 46 connected to the mounting plate 41, a screw 44 movably connected to the articulated seat 46, and a screw block 45 screwed to the screw 44. The screw block 45 is also connected to the slider 43, and the slider 43 is connected to the bottom of the laser generator 21. By rotating the screw 44, the slider 43 can be adjusted, synchronously driving the distance between the relative rollers 100 of the laser assembly 2. To facilitate manual adjustment of the screw 44, a handle or turntable 47 is also connected to one end of the screw 44 located on the articulated seat 46.

[0048] The driving member 6 is a cylinder, which is connected to the movable plate 12, and the movable plate 12 is also connected to the slide 43, so that the linear drive module 1 can synchronously drive the laser assembly 2 and the dust removal assembly 3 to move synchronously laterally, and the dust removal assembly 3 is controlled by the longitudinal movement of the driving member 6, and the focusing screw assembly 4 controls the longitudinal movement of the laser assembly 2.

[0049] It should be noted that the roller surface laser mobile dust removal equipment 200 of this embodiment also includes a controller, such as a CPU or PLC, which stores program instructions for controlling the linear drive module 1, the laser assembly 2, the dust removal assembly 3, the dust removal hood transverse drive module 5 and the drive member 6 to perform corresponding actions according to the preset logic to complete the laser removal of dust on the roller surface.

[0050] See also Figure 9 In this embodiment, a single laser assembly 2 is used to remove laser dust from the surface of the roller 100. Since the roller surface of the roller 100 is large, a single laser assembly 2 can only clean a small block area 10 at a time. Figure 9As shown, the block area 10 is the part that has been cleaned, and the remaining roller surface is the uncleaned part 20. The working process of the roller surface laser mobile dust removal device 200 of this embodiment is as follows:

[0051] According to the diameter of the roller 100, the linear drive module 1 is adjusted so that the laser assembly 2 is located at a suitable focal length position;

[0052] The driving member 6 drives the dust removal assembly 3 close to the roller surface to the set position;

[0053] The laser assembly 2, the dust cover transverse drive module 5, and the dust removal assembly 3 are started to perform laser ablation and vaporization treatment on the block area 10. In this step, the dust cover 31 is controlled by the dust cover transverse drive module 5 to follow the movement of the laser beam to quickly and timely discharge the vaporized dust. The dust removal cavity of the dust cover 31 is a relatively narrow and long cavity.

[0054] After the current block area 10 is processed, the roller 100 rotates a certain angle so that the laser width of the laser assembly 2 is just adjacent to the block area 10 that has been processed previously, and so on, so that the entire axially uniformly wide annular roller surface is processed.

[0055] The linear drive module 1 drives the laser assembly 2 and the dust removal assembly 3 to move a certain distance again, so that in the axial direction of the roller 100, the beam scanning width of the laser assembly 2 is adjacent to one of the block areas 10 that have completed surface cleaning in the axial direction of the roller surface, and then repeats the above steps until the entire roller surface of the roller 100 is finally cleaned.

[0056] The roller surface laser mobile dust removal equipment of this embodiment controls the dust removal component and the laser component to be moved synchronously by a linear drive module, and the dust removal component is driven to move synchronously by a dust cover transverse drive module. The dust removal hood of the dust removal component only needs to perform wind knife dust removal on the laser beam dust removal path of the laser component at a time, and there is no need to use a large wind hood to remove dust from the entire roller surface. The wind field has good uniformity, low energy consumption, low cost, and reduces the number of transverse movements of the laser component, thereby improving the dust removal efficiency.

[0057] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader. However, they do not limit the implementation of the present invention to these examples. Any technical extension or reinvention based on the present invention is protected by the present invention. The scope of protection of the present invention shall be determined by the claims.
