[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present invention. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise stated, the orientation words such as "upper" and "lower" generally refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; and "inner" and "outer" refer to the outline of the device.

[0044] Referring to Figure 1 As shown in the figure, an embodiment of the present application provides a welding dust removal mechanism 100, including a frame 110, a welding assembly 120 and a dust removal assembly 130. The welding assembly 120 is movably connected to the frame 110 and is used for welding the battery; and at least part of the dust removal assembly 130 is connected to the welding assembly 120 and is used for removing dust.

[0045] During the process of welding the battery through the welding assembly 120, since at least part of the dust removal assembly 130 is connected to the welding assembly 120, the dust removal assembly 130 can move simultaneously with the welding assembly 120. While the welding assembly 120 is performing welding, the dust removal assembly 130 can synchronously remove dust, and the dust removal effect is good.

[0046] In this embodiment, by arranging at least part of the dust removal assembly 130 on the welding assembly 120, it is possible to remove dust while welding, thereby improving the technical problem that it is difficult to absorb the welding slag and soot generated during the welding process.

[0047] In some embodiments, referring to Figures 2 to 5 As shown, the dust removal assembly 130 includes a dust collection box 131 and a suction hood 132. The dust collection box 131 is connected to the frame 110 and is located below the welding assembly 120, and is used to collect the dust that falls onto the frame 110. The suction hood 132 is connected to the welding assembly 120 and is used to suck the dust around the welding assembly 120. Therefore, in this embodiment, during the process of the welding assembly 120 welding the battery, large particles of dust are likely to fall on the frame 110, and small particles of dust are likely to float around the welding assembly 120. At this time, the dust collection box 131 can collect the dust that falls on the frame 110, and the suction hood 132 can suck the dust that floats around the welding assembly 120. The dust collection box 131 and the suction hood 132 play a cooperative role to ensure that both the fallen large particles of dust and the floating small particles of dust can be removed, and the dust removal efficiency is high.

[0048] It should be further noted that in this embodiment, the dust collection box 131 can collect large particles of dust that fall on the frame 110, while the suction hood 132 can suck the fine dust that floats around the battery during welding. Therefore, the welding dust removal mechanism 100 of this embodiment can remove large particles of dust and fine dust respectively, avoiding the influence on the welding efficiency caused by the excessive suction capacity of the suction hood 132, preventing the decrease of the welding efficiency, reducing energy consumption and cost; at the same time, it can also avoid the insufficient adsorption capacity of the dust due to the too small suction capacity of the suction hood 132, prevent the decrease of the dust removal efficiency, and ensure the product quality of battery welding.

[0049] In some embodiments, referring to Figure 3As shown, the welding assembly 120 includes a welding head 121. A dust suction hole 133 is provided on the dust suction hood 132, and the welding head 121 and the dust suction hole 133 are arranged adjacent to each other. Accordingly, the dust suction hole 133 can be closer to the welding point of the battery, reducing the diffusion path of dust and spatter generated during welding in the air, so that they can be more efficiently sucked into the dust suction hole 133, that is, it can ensure that the dust suction hole 133 can suck the dust floating near the welding head 121 during welding, prevent the dust from falling back onto the surface of the battery, ensure the dust removal efficiency, reduce the adverse effects on the battery and the equipment, and ensure the product quality.

[0050] It should be further noted that, in this embodiment, the welding assembly 120 is a laser welding assembly 120, and the welding head 121 is a laser welding head 121. There is less welding smoke, spatter and harmful gases generated during laser welding. Moreover, during the welding process of the laser welding head 121, the laser beam has no physical contact with the battery, avoiding mechanical wear and physical damage to the battery. In addition, the weld formed by laser welding is smooth and flat, usually without subsequent grinding or trimming, reducing the processing time and cost, and ensuring the product quality of battery welding.

[0051] In some embodiments, referring to Figures 3 to 5 As shown, the dust suction hood 132 is arranged around the welding head 121. The dust suction hood 132 is provided with a plurality of dust suction holes 133, and the plurality of dust suction holes 133 are arranged around the welding head 121. In this embodiment, the plurality of dust suction hoods 132 surround the welding head 121 inside, enabling full coverage of the welding area, effectively capturing the dust and spatter generated during welding, and preventing them from spreading to the surrounding environment. In addition, the design of the plurality of dust suction holes 133 increases the dust suction area, allowing the dust to be quickly sucked from multiple directions, thus significantly improving the dust suction efficiency.

[0052] It can be understood that arranging the dust suction hood 132 around the welding head 121 can also ensure the synchronous movement of the dust suction hood 132 and the welding head 121, without interfering with the welding operation of the welding head 121, and ensuring the welding efficiency of the battery.

[0053] In some embodiments, referring to Figures 3 to 5 As shown, the dust suction hole 133 is a strip-shaped hole, and the extending direction of the dust suction hole 133 is the same as the extending direction of the welding head 121. The strip-shaped hole has a larger dust suction area and can more effectively capture the dust and spatter generated during welding. When the extending direction of the dust suction hole 133 is set to be the same as the extending direction of the welding head 121, it can better cover the welding area, reduce dust diffusion, thus ensuring the dust removal effect of the dust suction hole 133 during welding, avoiding adverse effects on the battery and the equipment, and ensuring the product quality.

[0054] In some embodiments, the dust suction hole 133 is a square hole, and the length of the dust suction hole 133 is 340 mm to 360 mm; the width of the dust suction hole 133 is 10 mm to 30 mm; specifically, the length of the dust suction hole 133 is 350 mm, and the width of the dust suction hole 133 is 20 mm.

[0055] In some embodiments, the dust suction hole 133 is a circular hole, the diameter of the dust suction hole 133 is 90 mm to 130 mm; the depth of the dust suction hole 133 is 25 mm to 65 mm; specifically, the diameter of the dust suction hole 133 is 110 mm, and the depth of the dust suction hole 133 is 45 mm.

[0056] Through the setting of the above parameters, the size of the dust suction hole 133 can be made appropriate, avoiding the situation that dust cannot be fully sucked into the dust suction hood 132 due to the small size of the dust suction hole 133, and at the same time avoiding the situation that dust cannot be contained in the dust suction hood 132 due to the large size of the dust suction hole 133, so as to ensure that the suction capacity of the dust suction hole 133 is concentrated in the welding area, ensure the dust removal efficiency of the dust suction hood 132, avoid adverse effects on the battery and equipment, and ensure the product quality of battery welding.

[0057] At the same time, by setting the length and width of the dust suction hole 133, it can be matched with the size of the welding head 121 and the range of the welding area, so as to more accurately cover the welding points, which helps to capture dust and spatter in time during the welding process and reduce the possibility of dust spreading to the surrounding environment.

[0058] In some embodiments, the dust removal assembly 130 further includes a first dust removal pipeline. One end of the first dust removal pipeline is communicated with the dust suction hole 133, and the other end of the first dust removal pipeline is used to connect a first air extraction device. During the welding process, the first air extraction device is turned on, and the first air extraction device extracts air at the dust suction hood 132 through the first dust removal pipeline, so that the dust floating around the battery can be smoothly adsorbed into the dust suction hood 132 and discharged through the first dust removal pipeline.

[0059] In some embodiments, both ends of the first dust removal pipeline are detachably connected to the dust suction hood 132 and the first air extraction device respectively. The disassembly is simple and convenient for maintenance and cleaning. When the first dust removal pipeline fails, the damaged parts can be quickly replaced without large-scale repair or replacement of the entire welding dust removal mechanism 100, thus significantly reducing the maintenance cost and downtime.

[0060] It should also be noted that, in the present embodiment, the two ends of the first dust removal pipe are respectively locked to the dust hood 132 and the first exhaust device by means of buckles, which facilitates disassembly and assembly, and can also quickly replace damaged parts without the need for large-scale maintenance or replacement of the entire welding dust removal mechanism 100, thereby significantly reducing maintenance costs and downtime.

[0061] In some embodiments, the first dust removal duct is provided in plurality, and the plurality of the first dust removal ducts are evenly distributed along the outer periphery of the dust hood 132. Accordingly, it can be ensured that the adsorption force of each first exhaust device in each direction on the dust hood is uniform, thereby ensuring that the dust hood 132 can remove the dust around the welding head 121 and ensure the dust removal rate.

[0062] In some embodiments, reference Figures 3 to 5 As shown, a dust removal chamber 1321 is provided in the dust hood 132, and a plurality of dust collection holes 133 are respectively connected to the dust removal chamber 1321. A plurality of first dust removal pipes are provided and are all connected to the dust removal chamber 1321, and the plurality of first dust removal pipes are evenly distributed along the outer periphery of the dust hood 132. In this embodiment, the dust removal chamber 1321 is arranged to pass through the dust hood 132, and a plurality of first dust removal pipes are evenly distributed along the outer periphery of the dust hood 132, which can ensure that the adsorption capacity of the dust hood 132 is uniform, so that the airflow is evenly distributed in the dust removal chamber 1321, avoiding excessive or weak local airflow, thereby improving the dust removal efficiency and reducing the system energy consumption, and the dust can be smoothly discharged through the first dust removal pipe after being adsorbed to the dust removal chamber 1321, reducing the accumulation of dust in the dust hood 132, avoiding clogging of the dust collection holes 133, and ensuring the dust removal efficiency.

[0063] It should be further explained that, in the present embodiment, four first dust removal pipes are provided, and the four first dust removal pipes are evenly spaced. In other embodiments, different numbers of first dust removal pipes may be provided according to specific dust removal needs.

[0064] In some embodiments, the dust removal assembly 130 further includes a second dust removal pipe, one end of which is connected to the dust collection box 131, and the other end of which is used to connect to a second exhaust device. In this embodiment, the dust collection box 131 extends along the length direction of the welding track of the battery, so when dust falls on the rack 110 and is collected by the dust collection box 131, the dust in the dust collection box 131 can be removed through the second dust removal pipe to prevent dust from accumulating in the dust collection box 131.

[0065] It can be understood that, in the present embodiment, a plurality of the second dust removal pipes are provided, and the plurality of the second dust removal pipes are evenly spaced apart, and different numbers of second dust removal pipes can be provided according to specific dust removal needs.

[0066] It should be further noted that during the welding process of the welding assembly 120, the second air extraction device can also be opened simultaneously. Therefore, all the dust falling on the frame 110 can be adsorbed into the dust collection box 131 and finally discharged through the second dust removal pipeline, thereby ensuring the dust removal efficiency.

[0067] In some embodiments, both ends of the second dust removal pipeline are detachably connected to the dust collection box 131 and the second air extraction device respectively, which is simple to disassemble and convenient for maintenance and cleaning.

[0068] It should also be noted that in this embodiment, the second dust removal pipeline is locked on the dust collection box 131 and the second air extraction device respectively through buckles, which is convenient for disassembly and assembly. When the second dust removal pipeline fails, the damaged components can be quickly replaced without large-scale repair or replacement of the entire welding dust removal mechanism 100, thus significantly reducing the maintenance cost and downtime.

[0069] In some embodiments, referring to Figure 1 As shown, a first moving component 140 is further connected to the frame 110. The first moving component 140 is connected to the welding component 120 and drives the welding component 120 to move to realize the welding of the battery. During the welding process, by driving the welding component 120 to move through the first moving component 140, the welding component 120 can be smoothly moved to the part of the battery that needs to be welded, ensuring the welding work of the battery.

[0070] It can be understood that referring to Figure 1 and Figure 3 As shown, in this embodiment, the first moving component 140 includes an X-axis moving component 141, a Y-axis moving component 142, and a Z-axis moving component 143. Therefore, it can be ensured that the welding component 120 can move into place in all directions, ensuring the welding effect of the welding component 120 on the battery.

[0071] In some embodiments, a welding dust removal mechanism 100 further includes a second moving component 150. The second moving component 150 is used to move the battery to transfer the battery to the frame 110. In this embodiment, through the second moving component 150, the battery can be transferred from the previous process to the frame 110 to facilitate the welding work and the dust removal work.

[0072] In some embodiments, referring to Figure 1As shown, a fixing component 160 is further connected to the frame 110, and the fixing component 160 is used to fix the battery. In order to avoid affecting the welding effect due to the displacement of the battery during the welding process, in this embodiment, the battery is fixed by the fixing component 160, thereby preventing the phenomenon of battery displacement.

[0073] It should be further noted that, referring to Figure 1 As shown, in this embodiment, there are multiple groups of the welding components 120, which can simultaneously perform welding and dust removal operations on multiple batteries. Correspondingly, there are also multiple fixing components 160.

[0074] In some embodiments, referring to Figure 1 As shown, the fixing component 160 includes two first clamping plates 161 and two first driving members 162. The first clamping plates 161 are movably connected to the frame 110. The first driving members 162 are connected to the first clamping plates 161 and drive the first clamping plates 161 to move. Among them, the first driving members 162 can drive the two first clamping plates 161 to move towards or away from each other to clamp or release the battery in the first direction of the battery. When the battery moves to an appropriate position following the second moving component 150, the first driving members 162 drive the first clamping plates 161 to move, and the two first clamping plates 161 move towards each other, thereby clamping the first direction of the battery and realizing the fixation of the battery in the first direction.

[0075] In some embodiments, at least one of the first clamping plates 161 is provided with a sensor for detecting the in-place situation of the battery. When the sensor detects that the battery is in place, the first driving members 162 drive the two first clamping plates 161 to move towards each other, thereby clamping the first direction of the battery and realizing the fixation of the battery in the first direction.

[0076] In some embodiments, referring to Figure 1 As shown, the fixing component 160 includes two second clamping plates 163 and two second driving members 164. The second clamping plates 163 are movably connected to the frame 110. The second driving members 164 are connected to the second clamping plates 163 and drive the second clamping plates 163 to move. Among them, the second driving members 164 can drive the two second clamping plates 163 to move towards or away from each other to clamp or release the battery in the second direction of the battery. When the battery moves to an appropriate position following the second moving component 150, the second driving members 164 drive the second clamping plates 163 to move, and the two second clamping plates 163 move towards each other, thereby clamping the second direction of the battery and realizing the fixation of the battery in the second direction.

[0077] In some embodiments, at least one of the second clamping plates 163 is provided with a sensor for detecting the in-place condition of the battery. When the sensor detects that the battery is in place, the second driving member 164 drives the two second clamping plates 163 to move towards each other, thereby clamping the second direction of the battery to achieve fixation of the battery in the second direction.

[0078] It should be further noted that, in this embodiment, the two first clamping plates 161 are used for clamping and fixing the battery in the left and right directions, and the two second clamping plates 163 are used for clamping and fixing the battery in the up and down directions.

[0079] In summary, in this embodiment, when the battery moves to the rack 110 from the previous step following the second moving component 150, the sensor can detect that the battery has moved in place and drive the first driving member 162 and the second driving member 164, so that the two first clamping plates 161 move towards each other to clamp the first direction of the battery to achieve fixation of the battery in the first direction, and the two second clamping plates 163 move towards each other to clamp the second direction of the battery to achieve fixation of the battery in the second direction.

[0080] The first moving component 140 drives the welding component 120 to move. The first moving component 140 includes an X-axis moving component 141, a Y-axis moving component 142, and a Z-axis moving component 143. Therefore, the welding head 121 can accurately align with the welding part of the battery; the welding head 121 is started, and at the same time, the first air extraction device and the second air extraction device are turned on; the welding head 121 moves along the X-axis moving component 141 to achieve welding of the bipolar column cover plate of the battery; during the moving process, large particles of dust fall into the dust collection box 131 and are then sucked away through the second dust removal pipeline, while fine dust is sucked away by the dust suction hood 132, and four first dust removal pipelines are connected to the dust suction hood 132. Accordingly, the four first dust removal pipelines can suck fine dust from all directions.

[0081] After the welding of the battery is completed, the X-axis moving component 141, the Y-axis moving component 142, and the Z-axis moving component 143 all move back to their original positions, driving the welding component 120 to move to the initial position, and driving the first driving member 162 and the second driving member 164, so that the two first clamping plates 161 move away from each other to achieve release of the battery in the first direction, and the two second clamping plates 163 move away from each other to achieve release of the battery in the second direction; driven by the second moving component 150, the battery rotates and moves to the next station to complete the welding and dust removal processes.

[0082] The above has introduced the embodiments of the present invention in detail. Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
