[0033] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] See also Figures 1 to 12 As shown, this utility model provides a dust removal device, including a dust removal box 1. A cutting bottom plate 5 is provided inside the dust removal box 1. The cutting bottom plate 5 divides the dust removal box 1 to form a first dust removal chamber 128. A first partition 131 is horizontally provided in the first dust removal chamber 128. The first partition 131 divides the first dust removal chamber 128 into multiple dust removal channels. A dust removal channel is provided on the cutting bottom plate 5, and the dust removal channel connects to the dust removal channels.

[0035] In the above technical solution, the dust collection box 1 mainly provides installation space for the various components of the cutting equipment, while forming a cutting area inside the box to ensure that the cutting and dust removal processes are carried out within a limited space. The cutting base plate 5 is used to divide the dust collection box 1 to form a first dust collection chamber 128, and also provides support for the electrode sheet to be cut. A dust removal channel is provided on the cutting base plate 5, which connects the cutting area and the dust collection chamber, allowing the dust generated during the cutting process to flow from the cutting area to the dust collection chamber, reducing dust accumulation in the cutting area and improving the overall dust removal efficiency. The function of the first partition 131 is to divide the first dust collection chamber 128 into multiple dust collection channels. A large amount of dust generated during cutting flows into the first dust collection chamber 128 through the dust removal channel. By setting the first partition 131 to divide the outward flow path of the dust, the outward flow trajectory of the dust is lengthened, and the multiple dust collection channels formed by the partition allow the dust to be retained in the channels as much as possible, thereby reducing the escape of dust and improving the dust removal efficiency and effect of the dust collection equipment.

[0036] In one embodiment of the present invention, the dust removal box 1 includes a first dust removal component 11 and a second dust removal component 12. The first dust removal component 11 and the second dust removal component 12 are arranged opposite to each other along the X-axis. The first dust removal component 11 includes a first side plate 111. A first partition 131 is disposed on the inner wall of the first side plate 111 and extends toward the second dust removal component 12. A cutting bottom plate 5 is installed on the end face of the first partition 131 facing the second dust removal component 12.

[0037] In the above technical solution, the first dust removal component 11 and the second dust removal component 12 are arranged opposite each other along the X-axis, and the two are combined to form a dust removal box 1, thereby effectively limiting the diffusion range of dust. The first dust removal component 11 is used to provide an installation base for the first partition 131 and the cutting base plate 5. The cutting base plate 5 is installed on the end face of the first partition 131 facing the second dust removal component 12, dividing the dust removal box 1 to form a first dust removal chamber 128. The first partition 131 is used to divide the first dust removal chamber 128 into multiple dust removal channels. Designing the dust removal box 1 as a split structure composed of the first dust removal component 11 and the second dust removal component 12 allows the equipment to adjust the spacing between the first dust removal component 11 and the second dust removal component 12 according to the size of the electrode to be cut and specific production requirements, thereby enhancing the flexibility of the equipment and ensuring the cutting quality of electrode sheets under different sizes or cutting conditions.

[0038] In one embodiment of the present invention, the internal chamber of the first dust removal component 11 is a first dust removal chamber 128, and two first partitions 131 are spaced apart along the Z-axis on the inner wall of the first side plate 111. The two first partitions 131 divide the first dust removal chamber 128 into a middle dust collection area and a dust blocking area located on the upper and lower sides of the dust collection area. The dust removal channel connects to the dust collection area.

[0039] In the above technical solution, the first partition 131 is used to separate the first dust removal chamber 128 to form a dust collection area and a dust blocking area. The two first partitions 131 are arranged at intervals along the Z-axis on the inner wall of the first side plate 111 to separate and form a dust collection area located in the middle of the first dust removal chamber 128 and a dust blocking area located on the upper and lower sides of the dust collection area. The dust collection area is connected to the cutting area through the dust removal channel. The dust generated during cutting is diffused to the dust collection area through the dust removal channel, reducing the accumulation of dust in the cutting area and improving the overall dust removal efficiency. When dust escapes from the dust collection area, it first passes through the gap between the first partition 131 and the cutting base plate 5. During this process, the first partition 131 provides initial obstruction for the dust. Then, the dust escaping from the dust collection area flows into the dust blocking area, which further obstructs and retains the dust. A small amount of dust escaping into the dust blocking area is also sucked away by the negative pressure of the suction components, thereby further reducing the amount of dust escaping to the outside of the dust removal equipment. By setting the first partition 131, the path length of dust overflowing from the dust collection area to the external environment is significantly increased. At the same time, the first partition 131 and the dust collection area and dust blocking area formed in the first dust removal chamber 128 also further obstruct and retain the dust, thereby reducing the escape of dust and improving the dust removal efficiency and effect of the dust removal equipment.

[0040] In one embodiment of the present invention, the dust removal device further includes an installation part 132, which is disposed in the second dust removal component 12. The installation part 132 divides the second dust removal component 12 to form a cutting chamber 121 and a second dust removal chamber 122. The cutting chamber 121 is the chamber between the installation part 132 and the cutting base plate 5.

[0041] In the above technical solution, the mounting part 132 can further subdivide the internal space of the second dust removal component 12 to form a cutting chamber 121 and a second dust removal chamber 122. The cutting chamber 121 is located between the mounting part 132 and the cutting base plate 5. It is the main working area for laser cutting electrodes and also the main area for generating cutting dust. A large amount of dust is concentrated in the cutting chamber 121 during the cutting process and diffuses into other chambers. The second dust removal chamber 122 can retain the dust diffused into the cutting chamber 121. In conjunction with other dust removal equipment installed in the second dust removal chamber 122, the dust removal effect and efficiency of the dust removal equipment can be further improved, and the amount of dust escaping from the second dust removal chamber 122 to the outside of the equipment can be reduced.

[0042] In one embodiment of the present invention, the dust removal equipment includes a pressure roller 14 and a mounting part 132. The pressure roller 14 includes a first pressure roller 141. The first pressure rollers 141 are arranged in pairs, one of which is rotatably mounted on the first dust removal assembly 11, and the other is rotatably mounted on the mounting part 132.

[0043] In the above technical solution, the mounting part 132 is used to mount the pressure roller 14, which is used to press and limit the electrode sheet and provide tension to the electrode sheet. The pressure roller 14 includes a pair of first pressure rollers 141, each of which is a pressure roller of equal diameter. One of the rollers is rotatably mounted on the first dust removal assembly 11, and the other is rotatably mounted on the mounting part 132. Before cutting, the electrode sheet to be cut is conveyed along the Z-axis. The first dust removal assembly 11 and the second dust removal assembly 12 of the dust removal equipment are respectively mounted on both sides of the electrode sheet. The first dust removal assembly 11 and the second dust removal assembly 12 can move relative to each other along the X-axis, so that the first pressure rollers 141 mounted on the first dust removal assembly 11 and the mounting part 132 respectively come into contact with the surfaces on both sides of the electrode sheet. During the cutting process, the first pressure rollers 141 on both sides of the electrode sheet limit the electrode sheet and keep the electrode sheet in a taut state, thereby reducing the swing or shaking of the electrode sheet during the cutting process and keeping the electrode sheet flat during the cutting process, thereby improving the cutting accuracy and stability.

[0044] In one embodiment of the present invention, the pressure roller 14 further includes a second pressure roller 142. The second pressure rollers 142 are arranged in pairs, one of which is rotatably disposed on the first dust removal assembly 11 and the other is rotatably disposed on the mounting part 132. The first pressure roller 141 is disposed above the second pressure roller 142. The second pressure roller 142 includes a narrow diameter section located in the middle of the second pressure roller 142 and a wide diameter section located at both ends.

[0045] In the above technical solution, two second pressure rollers 142 are respectively disposed on the first dust removal assembly 11 and the mounting part 132. The two second pressure rollers 142 contact the electrode surface from both sides of the electrode sheet. The second pressure rollers 142 are disposed below the first pressure roller 141 and are mainly used to limit the electrode sheet that has been cut and to ensure that the electrode sheet can still maintain tension after cutting. After cutting, the main cutting area of ​​the electrode sheet is concentrated in the middle of the electrode sheet width direction, while the two ends of the electrode sheet width direction are still uncut electrode sheets. The second pressure rollers 142 are pressure rollers with different diameters. The middle of the second pressure roller 142 is a thinner diameter section, and the two ends are thicker diameter sections. The thicker diameter sections contact the uncut electrode sheets at both ends of the electrode sheet width direction, so that the electrode sheet can still maintain sufficient tension and ensure the stability of electrode sheet transmission and cutting. The narrow section ensures that there is a gap between the roller body of the second pressure roller 142 and the cutting area on the electrode plate, preventing the second pressure roller 142 from directly pressing over the cut electrode tab, reducing the contact and pressure of the second pressure roller 142 on the cutting area, thereby avoiding the cutting-related problems caused by the electrode tab not being able to completely separate from the electrode plate in time after the cutting is completed.

[0046] In one embodiment of the present invention, the two first pressure rollers 141 on the first dust removal assembly 11 and the mounting part 132 are offset along the Z-axis direction, and the two second pressure rollers 142 on the first dust removal assembly 11 and the mounting part 132 are also offset along the Z-axis direction.

[0047] In the above scheme, the dust removal box 1 is designed as a split structure composed of a first dust removal component 11 and a second dust removal component 12. Two first pressure rollers 141 are respectively set on the first dust removal component 11 and the second dust removal component 12. When it is necessary to install and adjust the two first pressure rollers 141, separating the first dust removal component 11 and the second dust removal component 12 can provide sufficient space for the installation and adjustment of the first pressure rollers 141. The two first pressure rollers 141 are staggered along the Z-axis direction. When the first dust removal component 11 and the second dust removal component 12 are assembled along the X-axis direction, the two first pressure rollers 141 respectively set on the first dust removal component 11 and the second dust removal component 12 begin to contact the electrode and push the electrode to shift along the X-axis direction. Simultaneously, two second pressure rollers 142 are respectively disposed on the first dust removal assembly 11 and the second dust removal assembly 12. When it is necessary to install and adjust the two second pressure rollers 142, separating the first dust removal assembly 11 and the second dust removal assembly 12 provides sufficient space for the installation and adjustment of the second pressure rollers 142. The two second pressure rollers 142 are staggered along the Z-axis. When the first dust removal assembly 11 and the second dust removal assembly 12 are joined along the X-axis, the two second pressure rollers 142 disposed on these two assemblies also begin to contact the electrode sheet and push the electrode sheet to shift along the X-axis. The first pressure roller 141 and the second pressure roller 142 cooperate to push the electrode sheet entering the cutting area to shift along the X-axis, thereby tensioning the electrode sheet, reducing bending or shaking of the electrode sheet during the cutting process, and thus improving the cutting quality.

[0048] In one embodiment of this utility model, the dust removal equipment further includes an air knife assembly 3, which is disposed on the dust removal box 1. The air knife assembly 3 includes an air inlet connector 31 and an air delivery pipe 32. One end of the air delivery pipe 32 is threadedly connected to the air inlet connector 31, and the other end of the air delivery pipe 32 is sealed. The air delivery pipe 32 has a blowing groove 33 in the radial direction, and the blowing groove 33 extends in the axial direction. The blowing groove 33 communicates with the air delivery pipe 32, and the air delivery pipe 32 extends into the dust removal box 1.

[0049] In the above technical solution, the air inlet connector 31 is the airflow inlet of the air knife assembly, used to connect to an external air source such as a positive pressure fan or compressed air system, thereby providing high-speed airflow to the air knife assembly. The air delivery pipe 32 is mainly used to transport airflow. One end of the air delivery pipe 32 is threadedly connected to the air inlet connector 31, and the other end is sealed. The sealed end prevents gas leakage and ensures that the gas is only ejected through the blowing groove 33. The air delivery pipe 32 extends into the dust collector housing 1, allowing the air knife assembly to directly act on the internal space of the dust collector housing 1, improving dust removal efficiency. The blowing groove 33 is a radially opened through groove on the air delivery pipe 32, extending axially along the air delivery pipe 32. By setting the blowing groove 33, the outflow of airflow in the air delivery pipe 32 is guided, allowing the airflow to be concentrated and blown out in one direction, thereby ensuring that the airflow is ejected at high speed and in a straight line to form an air wall. The wind wall can blow the dust generated during the cutting process toward the dust collection component, improving dust removal efficiency. At the same time, the wind wall can act as a physical barrier to block the dust, preventing the dust from leaking to the outside through the holes or gaps in the dust collection box 1 after passing through the wind wall.

[0050] In one embodiment of this utility model, two air blowing grooves 33 are provided on the air supply pipe 32. The two air blowing grooves 33 are arranged opposite to each other along the Y-axis and are connected to the air supply pipe 32.

[0051] In the above technical solution, the two air blowing slots 33 arranged opposite each other along the Y-axis can generate high-speed airflow on both sides of the air knife assembly at the same time, forming a bidirectional air wall along the Y-axis inside the dust collector 1, ensuring that the airflow distribution on both sides of the air knife assembly is more uniform. When using an air knife assembly with a single-sided air-blowing groove 33, the air knife assembly needs to be placed at one end of the dust collector 1 along the Y-axis, and the air-blowing groove 33 needs to be directed towards the other end of the dust collector 1 along the Y-axis to spray airflow to form an air wall, thereby blocking dust and preventing dust from escaping. However, as the spray distance increases, the wind force will decrease rapidly. Therefore, the wind force at the end of the air wall away from the air knife assembly is weaker, which may lead to a decrease in the dust blocking effect. However, when using the air knife assembly with two opposing air-blowing grooves 33 in the above technical solution, the air knife assembly is placed in the middle of the dust collector 1 along the Y-axis, and the two air-blowing grooves 33 are arranged opposite each other along the Y-axis. This shortens the length of the air wall that needs to be formed on one side of the air knife assembly, thereby reducing the impact of wind force attenuation on the dust blocking effect at the end of the air wall, and thus improving the dust blocking effect of the air wall.

[0052] In one embodiment of the present invention, the air knife assembly 3 includes a first air knife 35, which is disposed on the first dust removal assembly 11, and the air blowing groove 33 of the first air knife 35 faces the dust suction hood 21.

[0053] In the above technical solution, the first air knife 35 is mounted on the first dust removal assembly 11, the air supply pipe 32 of the first air knife 35 extends into the first dust removal chamber 128, and the air blowing groove 33 of the first air knife 35 faces the dust collection hood 21, so that the dust in the first dust removal chamber 128 is blown towards the dust collection assembly 2 under the action of high-speed airflow, thereby improving the dust removal efficiency and effect in the first dust removal chamber 128. At the same time, since the cutting base plate 5 is provided with a dust removal channel connecting the cutting area and the dust removal chamber, the airflow blown into the first dust removal chamber 128 by the first air knife 35 will also flow to the cutting area through the dust removal channel, thereby forming an air film between the electrode sheet and the cutting base plate 5 in the cutting area, so that the electrode sheet is in a suspended state, thereby supporting the electrode sheet to complete the electrode tab cutting and avoiding the problem of welding slag on the cutting base plate 5 scratching the electrode sheet.

[0054] In one embodiment of the present invention, the air knife assembly 3 further includes a second air knife 36, which is disposed on the second dust removal assembly 12 and extends into the cutting chamber 121, with the air blowing groove 33 of the second air knife 36 facing the dust suction hood 21.

[0055] In the above technical solution, the cutting chamber 121 is the main chamber for electrode cutting. Most of the dust generated during the cutting process accumulates in the cutting chamber 121. The second air knife 36 is mounted on the second dust removal assembly 12 and extends into the cutting chamber 121. The air blowing groove 33 of the second air knife 36 faces the dust collection hood 21, ensuring that the dust and waste generated during the cutting process can be directly and quickly blown towards the dust collection assembly, reducing the residence time of dust in the cutting chamber 121 and significantly improving dust removal efficiency and effect. At the same time, the air blowing groove 33 of the second air knife 36 faces the dust collection hood 21, forming an air wall along the Y-axis direction of the dust collection box 1 on the side of the second cutting opening 126 facing the cutting chamber 121, thereby blocking the dust in the cutting chamber 121 and preventing dust from leaking from the second cutting opening 126 to the second dust removal chamber 122.

[0056] In one embodiment of the present invention, the air knife assembly 3 further includes a third air knife 37, which is disposed on the second dust removal assembly 12 and extends into the second dust removal chamber 122. The air blowing groove 33 of the third air knife 37 faces the dust suction hood 21.

[0057] In the above technical solution, the third air knife 37 is used to blow the dust and waste in the second dust removal chamber 122 toward the dust collection component, thereby improving the dust removal efficiency and effect of the dust removal equipment. At the same time, the air blowing groove 33 of the third air knife 37 faces the dust collection hood 21, and high-speed airflow is blown out from the air blowing groove 33 to form an air wall along the Y-axis direction of the dust collection box 1 on the side of the first cutting opening 125 facing the second dust removal chamber 122, thereby blocking the dust in the second dust removal chamber 122 and preventing the dust from leaking to the outside of the dust removal equipment through the first cutting opening 125.

[0058] In one embodiment of the present invention, the air knife assembly 3 further includes an adjustment part 34, which is fixed on the air supply pipe 32. The adjustment part 34 is rotatably disposed outside the dust collection box 1 and can drive the air supply pipe 32 to rotate inside the dust collection box 1.

[0059] In the above technical solution, the adjustment part 34 is fixed on the air supply pipe 32. By rotating the adjustment part 34 outside the dust collection box 1, the operator can adjust the angle and orientation of the air supply pipe 32 and the air blowing groove 33 on it inside the dust collection box 1 from the outside, thereby accurately controlling the airflow direction and enhancing the dust removal effect.

[0060] In one embodiment of the present invention, the dust removal device further includes a dust collection component 2, which includes a dust collection hood 21 and a dust collection pipe 22. The dust collection hood 21 covers the side of the dust removal box 1 in the Y-axis direction, and the dust collection pipe 22 is disposed on the dust collection hood 21 and communicates with the internal cavity of the dust removal box 1.

[0061] In the above technical solution, the dust collection component 2 is used to capture and remove dust and waste generated during the cutting process. The dust collection hood 21 covers the side of the dust collection box 1 in the Y-axis direction, forming a tight seal with the dust collection box 1 to prevent dust from escaping into the external environment through the gap between the dust collection hood 21 and the dust collection box 1. The internal design of the dust collection hood 21 includes structures that optimize airflow, such as baffles, which can improve airflow guidance efficiency, ensuring that dust is efficiently captured and guided to the suction pipe 22, thereby improving dust removal efficiency.
