[0001] This application relates to the field of laser processing, and in particular to a dust removal component and a laser cleaning device. Background Technology

[0002] In the production process of new energy lithium batteries, cleaning the surface of the electrode sheets is a crucial step. Among related technologies, laser cleaning devices are used to clean the electrode sheets, but this process easily generates dust.

[0003] In related technologies, some dust removal components are used to remove dust from the cleaning area while laser cleaning the electrode plates. However, with current dust removal technologies, dust can easily escape from the cleaning area. Summary of the Invention

[0004] This application provides a dust removal component and a laser cleaning device to reduce the possibility of dust escaping.

[0005] In a first aspect, embodiments of this application provide a dust removal assembly for a laser cleaning device. The dust removal assembly includes: a first base having a first surface and a first side surface located on one side of the first surface; a second base including a first mounting portion and a second mounting portion connected to each other, the first mounting portion being connected to the first side surface such that the second mounting portion is erected on one side of the first surface, the second mounting portion having a dust suction port that can be connected to a negative pressure generating device; and a cover connected to the second mounting portion, the cover being configured to semi-circle to form an accommodating space on one side facing the first surface, the cover being spaced apart from the first surface, the end of the cover facing the second mounting portion having a first opening that connects the accommodating space to the dust suction port, and the surface of the cover opposite to the first surface having a light-transmitting window that allows laser light to pass through.

[0006] According to an embodiment of this application, a dust removal assembly is used in a laser cleaning device. The assembly includes a first base, a second base, and a cover. The second base includes a first mounting portion and a second mounting portion connected to each other. After the first mounting portion is connected to a first side of the first base, the second mounting portion can stand upright on one side of the first surface, providing a stable mounting position for the cover. After the cover is connected to the second mounting portion standing upright on one side of the first surface, a gap is created between the cover and the first surface, facilitating the passage of material to be laser-cleaned through the gap between the cover and the first surface. This facilitates continuous laser cleaning operations on the production line. In this embodiment, the cover is configured to semi-enclose a receiving space on the side facing the first surface, and a light-transmitting window is provided on the surface of the cover opposite to the first surface, allowing the laser to pass through. Therefore, the semi-enclosed design of the cover helps to concentrate dust within the receiving space formed by the semi-enclosed portion of the cover, improving control over dust flow, reducing interference from the external environment, and minimizing dust escape from the cover. The light-transmitting window ensures that the laser can properly clean the material to be laser-cleaned within the receiving space. In this embodiment, the end of the cover facing the second mounting part is provided with a first opening. The first opening connects the accommodating space with the dust suction port. The dust suction port can be connected to a negative pressure generating device, so that the dust generated by laser cleaning can be sucked out through the dust suction port in a timely manner, reducing the amount of dust retained in the accommodating space and facilitating the improvement of the laser cleaning effect.

[0007] According to any of the foregoing embodiments of the first aspect of this application, the light-transmitting window includes a second opening extending through the cover. In the above embodiments, the second opening extending through the cover ensures that the laser can pass through the light-transmitting window without damage, greatly reducing the attenuation or loss of the laser when passing through the light-transmitting window.

[0008] According to any of the foregoing embodiments of the first aspect of this application, the light-transmitting window includes: a second opening extending through the cover; and a light-transmitting element sealed to the edge of the second opening. In the above embodiments, the light-transmitting element is sealed to the edge of the second opening. This light-transmitting window ensures minimal attenuation or loss when laser light passes through, while further enhancing the cover's control over dust within the containment space and further preventing dust from escaping outwards.

[0009] According to any of the foregoing embodiments of the first aspect of this application, the end of the cover away from the second mounting portion is provided with a third opening. The dust removal assembly further includes: a blower located on the side of the cover away from the second mounting portion, the blower being connectable to a gas conveying device, the blower including a blower nozzle, the blower nozzle being opposite to the third opening and facing the receiving space. In the above embodiments, the dust removal assembly further includes a blower, which is connectable to a gas conveying device and blows air into the receiving space from the third opening through the blower nozzle. When dust is generated in the receiving space, the blower provides a positive pressure airflow from the third opening towards the first opening, while the suction port is connected to a negative pressure generating device to generate negative pressure, making it easier to efficiently draw dust out of the receiving space from the suction port, further improving dust removal efficiency.

[0010] According to any of the foregoing embodiments of the first aspect of this application, the dust removal assembly further includes: an adjustment frame connecting the blower to the cover, wherein at least a portion of the structure of the adjustment frame is movable relative to the cover to drive the blower to move, thereby adjusting the orientation of the blower nozzle. In the above embodiments, the dust removal assembly further includes an adjustment frame capable of driving the blower to move, thereby adjusting the orientation of the blower nozzle. When dust is generated in the containing space, by adjusting the orientation of the blower nozzle, the dust in different areas of the containing space can be flexibly guided, thereby improving the dust removal effect on certain dust accumulation areas within the containing space.

[0011] According to any of the foregoing embodiments of the first aspect of this application, the cover includes a top wall disposed opposite to the first surface and side walls located on both sides of the top wall. The side walls extend from the top wall toward the first surface, and there is a gap between the side walls and the first surface. The adjusting frame includes: a connecting member fixedly connected to the side wall of the cover and extending outward relative to the cover in a direction away from the second mounting portion; and a rotating member fixedly connected to the blowing member, the rotating member being rotatably connected to the connecting member, the axis of rotation of the rotating member relative to the connecting member being parallel to the first surface. In the above embodiments, by providing the connecting member and the rotating member, the orientation of the blowing nozzle is adjustable with a simplified, stable, and reliable structure. The axis of rotation of the rotating member relative to the connecting member is parallel to the first surface, making the angle between the air outlet direction and the first surface adjustable. This facilitates the comprehensive guidance of dust in the containing space by adjusting the orientation of the blowing nozzle, thereby improving the dust removal effect.

[0012] According to any of the foregoing embodiments of the first aspect of this application, the air outlet is a flat air outlet extending parallel to the first surface. In the above embodiments, when the wind speed generated by the gas conveying device remains constant, the flat air outlet can significantly increase the wind speed at the air outlet compared to air outlets of other shapes, thereby facilitating further improvement of dust removal efficiency.

[0013] According to any of the foregoing embodiments of the first aspect of this application, the cover includes a top wall, side walls, and a bent wall. The top wall is disposed opposite to the first surface, the side walls are located on both sides of the top wall, the side walls extend from the top wall toward the first surface, and a gap exists between the side walls and the first surface. The bent wall bends and extends from one end of the side wall toward the first surface in a direction away from the receiving space and away from the first surface. In the above embodiments, the cover includes a bent wall that bends and extends from one end of the side wall toward the first surface in a direction away from the receiving space and away from the first surface. When the material to be laser-cleaned enters the receiving space from outside the cover through the gap between the side wall and the first surface, the bent wall can provide guidance and smoothing function, ensuring that the material to be laser-cleaned smoothly enters the receiving space.

[0014] According to any of the foregoing embodiments of the first aspect of this application, the end of the cover facing the second mounting portion is provided with a connecting ear, and the connecting ear is provided with a connecting hole having a predetermined length in a direction perpendicular to the first surface. In the above embodiments, the connecting ear of the cover is provided with a connecting hole, and the connecting hole has a predetermined length in a direction perpendicular to the first surface. When the cover is connected to the second mounting portion through the connecting hole, the distance between the cover and the first surface can be adjusted, thereby adjusting the size of the distance between the cover and the first surface, making it convenient for the dust removal assembly to be used with materials of various thicknesses to be laser cleaned.

[0015] Secondly, embodiments of this application provide a laser cleaning apparatus, the laser cleaning apparatus comprising: a laser component; and a dust removal component according to any of the foregoing embodiments of the first aspect of this application, wherein the laser generated by the laser component can pass through the light-transmitting window of the dust removal component.

[0016] According to an embodiment of this application, a laser cleaning apparatus includes a laser component and a dust removal component. The dust removal component includes a first base, a second base, and a cover. The second base includes a first mounting portion and a second mounting portion connected to each other. After the first mounting portion is connected to a first side of the first base, the second mounting portion can be erected on one side of the first surface, providing a stable mounting position for the cover. After the cover is connected to the second mounting portion erected on one side of the first surface, a gap can be formed between the cover and the first surface, facilitating the passage of the material to be laser cleaned through the gap between the cover and the first surface, thus enabling continuous laser cleaning operation of the laser cleaning apparatus on the production line. In this embodiment, the cover is configured to semi-enclose a receiving space on the side facing the first surface, and the surface of the cover opposite to the first surface has a light-transmitting window that allows the laser to pass through. Therefore, the semi-enclosed design of the cover helps to concentrate dust in the receiving space formed by the semi-enclosed cover, improving the control of dust flow, reducing interference from the external environment, and reducing dust escape from the cover. The light-transmitting window ensures that the laser can properly laser clean the material to be laser cleaned in the receiving space. In this embodiment, the end of the cover facing the second mounting part is provided with a first opening. The first opening connects the accommodating space with the dust suction port. The dust suction port can be connected to a negative pressure generating device, so that the dust generated by laser cleaning can be sucked out through the dust suction port in a timely manner, reducing the amount of dust retained in the accommodating space and facilitating the improvement of the laser cleaning effect.

Figure 2 This is a three-dimensional schematic diagram from another perspective of one embodiment of the dust removal component of this application.

[0036] The dust removal assembly 100 includes a first base 110, a second base 120, and a cover 130. The first base 110 has a first surface S1 and a first side surface S2 located on one side of the first surface S1. The second base 120 includes a first mounting portion 121 and a second mounting portion 122 connected to each other. The first mounting portion 121 is connected to the first side surface S2, such that the second mounting portion 122 stands upright on one side of the first surface S1. The second mounting portion 122 is provided with a suction port 122a, which can be connected to a negative pressure generating device.

[0037] The cover 130 is connected to the second mounting portion 122. The cover 130 is configured to semi-circle and form a receiving space on the side facing the first surface S1, with a gap between the cover 130 and the first surface S1. The end of the cover 130 facing the second mounting portion 122 has a first opening K1, which connects the receiving space to the suction port 122a. The surface of the cover 130 opposite to the first surface S1 has a light-transmitting window T1, which allows laser light to pass through.

[0038] According to an embodiment of this application, a dust removal assembly 100 is used in a laser cleaning device. The assembly includes a first base 110, a second base 120, and a cover 130. The second base 120 includes a first mounting portion 121 and a second mounting portion 122 connected to each other. After the first mounting portion 121 is connected to a first side surface S2 of the first base 110, the second mounting portion 122 can be erected on one side of the first surface S1, providing a stable mounting position for the cover 130. After the cover 130 is connected to the second mounting portion 122 erected on one side of the first surface S1, a gap is created between the cover 130 and the first surface S1, facilitating the passage of material to be laser cleaned through the gap between the cover 130 and the first surface S1, thus enabling continuous laser cleaning operation of the laser cleaning device on the production line. In this embodiment, the cover 130 is configured to semi-enclose the first surface S1 to form a receiving space, and the surface of the cover 130 opposite to the first surface S1 is provided with a light-transmitting window T1, which allows the laser to pass through. Therefore, the semi-enclosed design of the cover 130 helps to concentrate dust in the receiving space formed by the semi-enclosed cover 130, improves the control of dust flow, reduces interference from the external environment, and reduces the escape of dust from the cover 130. The light-transmitting window T1 ensures that the laser can properly clean the material to be laser cleaned in the receiving space. In this embodiment, the end of the cover 130 facing the second mounting part 122 is provided with a first opening K1, which connects the receiving space to the suction port 122a. The suction port 122a can be connected to a negative pressure generating device, so that the dust generated by laser cleaning can be sucked out through the suction port 122a in a timely manner, reducing the amount of dust retained in the receiving space and improving the laser cleaning effect.

[0039] Figure 3 This is a perspective view of the cover in one embodiment of the dust removal component of this application. In some embodiments, the light-transmitting window T1 includes a second opening K2 that penetrates the cover 130.

[0040] In the above embodiment, the second opening K2, which penetrates the cover 130, ensures that the laser can pass through the light-transmitting window T1 without damage, greatly reducing the attenuation or loss of the laser when passing through the light-transmitting window T1. In other embodiments, the light-transmitting window T1 can be other structures.

[0041] Figure 4 This is a perspective view of the cover in an alternative embodiment of the dust removal component of this application. In this alternative embodiment, the light-transmitting window T1 includes a second opening K2 that penetrates the cover 130 and a light-transmitting element 139, the light-transmitting element 139 being sealed to the edge of the second opening K2.

[0042] In the above alternative embodiment, the light-transmitting element 139 is sealed to the edge of the second opening K2. The light-transmitting window T1 ensures minimal attenuation or loss when the laser passes through, while further enhancing the control of dust in the containment space by the cover 130, and further preventing dust from escaping outward.

[0043] like Figures 1 to 3 In some embodiments, the end of the cover 130 away from the second mounting portion 122 is provided with a third opening K3. In some embodiments, the dust removal assembly 100 further includes a blower 140. The blower 140 is located on the side of the cover 130 away from the second mounting portion 122. The blower 140 is capable of being connected to a gas delivery device. The blower 140 includes a blower nozzle 141, which is opposite to the third opening K3 and faces the receiving space.

[0044] In the above embodiment, the dust removal assembly 100 further includes a blower 140, which is connected to a gas delivery device and blows air into the accommodating space from the third opening K3 through the blower port 141. When dust is generated in the accommodating space, the blower 140 provides a positive pressure airflow from the third opening K3 to the first opening K1, while the suction port 122a is connected to a negative pressure generating device to generate negative pressure, which makes it easier for the dust in the accommodating space to be efficiently sucked out from the suction port 122a, further improving the dust removal efficiency.

[0045] like Figure 1 , Figure 2 In some embodiments, the dust removal assembly 100 further includes an adjustment frame 150 that connects the blower 140 to the cover 130. At least a portion of the structure of the adjustment frame 150 is movable relative to the cover 130 to move the blower 140, thereby adjusting the orientation of the air outlet 141. This adjustment frame 150, by moving the blower 140 and adjusting the orientation of the air outlet 141, allows for flexible and assisted guidance of dust in different areas of the containment space when dust is generated within the containment space, thus improving the dust removal effect on certain dust-accumulating areas within the containment space.

[0046] like Figure 3 In some embodiments, the cover 130 includes a top wall 131 disposed opposite to the first surface S1 and side walls 132 located on both sides of the top wall 131. The side walls 132 extend from the top wall 131 toward the first surface S1 and have a gap between the side walls 132 and the first surface S1.

[0047] Figure 5This is a perspective view of the cover, adjusting frame, and blowing component in one embodiment of the dust removal assembly of this application. In some embodiments, the adjusting frame 150 includes a connecting member 151 and a rotating member 152. The connecting member 151 is fixedly connected to the side wall 132 of the cover 130 and extends outward relative to the cover 130 in a direction away from the second mounting portion 122. The rotating member 152 is fixedly connected to the blowing component 140 and rotatably connected to the connecting member 151. The axis of rotation of the rotating member 152 relative to the connecting member 151 is parallel to the first surface S1.

[0048] In the above embodiment, by setting the connector 151 and the rotating member 152, the orientation of the air outlet 141 is adjustable with a simplified, stable and reliable structure. The rotation axis of the rotating member 152 relative to the connector 151 is parallel to the first surface S1, so that the angle between the air outlet direction of the air outlet 141 and the first surface S1 is adjustable. This facilitates the auxiliary guidance of dust in the containing space by adjusting the orientation of the air outlet 141, thereby improving the dust removal effect.

[0049] In some embodiments, the air outlet 141 is a flat air outlet extending parallel to the first surface S1. When the wind speed generated by the gas conveying device remains constant, this flat air outlet can significantly increase the wind speed at the air outlet 141 compared to air outlets of other shapes, thereby facilitating further improvement of dust removal efficiency.

[0050] like Figure 3 In some embodiments, the cover 130 includes a top wall 131, side walls 132, and a bent wall 133. The top wall 131 is disposed opposite to the first surface S1. The side walls 132 are located on both sides of the top wall 131, extending from the top wall 131 toward the first surface S1, with a gap between the side walls 132 and the first surface S1. The bent wall 133 extends from one end of the side wall 132 toward the first surface S1 in a direction away from the receiving space and away from the first surface S1.

[0051] In the above embodiment, the cover 130 includes a bent wall 133. The bent wall 133 bends and extends from one end of the side wall 132 toward the first surface S1 in a direction away from the receiving space and away from the first surface S1. When the material to be laser cleaned enters the receiving space from outside the cover 130 through the gap between the side wall 132 and the first surface S1, the bent wall 133 can provide guidance and have a smoothing function to ensure that the material to be laser cleaned enters the receiving space smoothly.

[0052] In some embodiments, the end of the cover 130 facing the second mounting portion 122 is provided with a connecting ear 134, and the connecting ear 134 is provided with a connecting hole H1 having a preset length in a direction perpendicular to the first surface S1. By providing a connecting hole H1 in the connecting ear 134 of the cover 130, and the connecting hole H1 having a preset length in a direction perpendicular to the first surface S1, when the cover 130 is connected to the second mounting portion 122 through the connecting hole H1, the distance between the cover 130 and the first surface S1 can be adjusted, thereby adjusting the size of the distance between the cover 130 and the first surface S1, making it easier for the dust removal assembly 100 to be used with materials of various thicknesses to be laser cleaned.

[0053] This invention also provides a laser cleaning device, which includes a laser component and a dust removal component 100 of any of the foregoing embodiments.

[0054] The laser component can generate laser light, which can clean specific contaminants from the surface of the material to be treated.

[0055] The dust removal assembly 100 includes a first base 110, a second base 120, and a cover 130. The first base 110 has a first surface S1 and a first side surface S2 located on one side of the first surface S1. The second base 120 includes a first mounting portion 121 and a second mounting portion 122 connected to each other. The first mounting portion 121 is connected to the first side surface S2, such that the second mounting portion 122 stands upright on one side of the first surface S1. The second mounting portion 122 has a suction port 122a, which can be connected to a negative pressure generating device. The cover 130 is connected to the second mounting portion 122. The cover 130 is configured to semi-circle a receiving space on the side facing the first surface S1, and the cover 130 is spaced apart from the first surface S1. The end of the cover 130 facing the second mounting portion 122 has a first opening K1, which connects the receiving space to the suction port 122a. The surface of the cover 130 opposite to the first surface S1 is provided with a light-transmitting window T1, which allows laser light to pass through. The laser light generated by the laser assembly can pass through the light-transmitting window T1 of the dust removal assembly 100.

The second base 120 includes a first mounting portion 121 and a second mounting portion 122 connected to each other. After the first mounting portion 121 is connected to a first side surface S2 of the first base 110, the second mounting portion 122 can be erected on one side of the first surface S1, providing a stable mounting position for the cover 130. After the cover 130 is connected to the second mounting portion 122 erected on one side of the first surface S1, a spaced-out arrangement is achieved between the cover 130 and the first surface S1, facilitating the passage of materials to be laser cleaned through the space between the cover 130 and the first surface S1, thus enabling continuous laser cleaning operation of the laser cleaning apparatus on the production line. In this embodiment, the cover 130 is configured to semi-enclose the first surface S1 to form a receiving space, and the surface of the cover 130 opposite to the first surface S1 is provided with a light-transmitting window T1, which allows the laser to pass through. Therefore, the semi-enclosed design of the cover 130 helps to concentrate dust in the receiving space formed by the semi-enclosed cover 130, improves the control of dust flow, reduces interference from the external environment, and reduces the escape of dust from the cover 130. The light-transmitting window T1 ensures that the laser can properly clean the material to be laser cleaned in the receiving space. In this embodiment, the end of the cover 130 facing the second mounting part 122 is provided with a first opening K1, which connects the receiving space to the suction port 122a. The suction port 122a can be connected to a negative pressure generating device, so that the dust generated by laser cleaning can be sucked out through the suction port 122a in a timely manner, reducing the amount of dust retained in the receiving space and improving the laser cleaning effect.

[0057] In some embodiments, the laser cleaning apparatus further includes a laser control system, which includes an image acquisition device and a laser controller. The image acquisition device and the laser controller are electrically connected to the laser component. Through image recognition by the image acquisition device and feedback control by the laser controller, the focusing position and power of the laser generated by the laser component can be monitored in real time, thereby facilitating adaptation to different cleaning or drilling requirements. In other embodiments, the laser generated by the laser component is controlled by preset timing logic.
