[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without 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" usually 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.

[0046] Referring to Figure 1 As shown, the present application provides a dust removal mechanism 100, including a frame 110, a fixing component 120, and a vacuum adsorption component 140. The fixing component 120 is connected to the frame 110 and is used for clamping and fixing the battery 300; the roller component 130 is movably connected to the frame 110 and is used for sticking and removing the dust on the surface of the battery 300; and the vacuum adsorption component 140 is used for adsorbing the dust on the battery 300 and / or for adsorbing the dust around the battery 300.

[0047] When the battery 300 is completed in welding and is transferred to the frame 110 of this embodiment from the previous steps, after the battery 300 moves to an appropriate position, the fixing component 120 can clamp and fix the battery 300, and the roller component 130 can move on the frame 110 and roll over the welded edge of the battery 300 to stick and remove the dust on the surface of the battery 300; at the same time, the vacuum adsorption component 140 can adsorb the dust on the surface of the battery 300. Therefore, through the combined action of the roller component 130 and the vacuum adsorption component 140, while the roller component 130 sticks away the surface debris and residues of the battery 300, it will not damage the battery 300. Finally, the debris and residues are sucked away by the vacuum dust removal method, with high roller pressing accuracy, good weld cleaning effect, and high dust removal efficiency.

[0048] In some embodiments, referring to Figure 2As shown, the roller assembly 130 includes a base plate 131, a first driving member 132, and a roller 133. The base plate 131 is movably connected to the frame 110, and the roller 133 is movably connected to the base plate 131. The roller 133 is used to remove the dust on the surface of the battery 300. The first driving member 132 is fixed on the base plate 131 and is connected to the roller 133 to drive the roller 133 to move relative to the base plate 131. Wherein, the moving direction of the base plate 131 is perpendicular to the moving direction of the roller 133. When the battery 300 moves to an appropriate position, by moving the base plate 131 and the roller 133, the roller 133 contacts the battery 300, and the first driving member 132 makes the roller 133 move along the welding edge of the cover plate and the side aluminum shell of the battery 300 to remove the dust on the surface of the battery 300. While quickly removing the dust on the surface of the battery 300, it will not cause damage to the battery 300.

[0049] In some embodiments, referring to Figure 1 As shown, the roller assembly 130 further includes an angle meter 134. The roller 133 is connected to the first driving member 132 through the angle meter 134 to adjust the inclination angle of the roller 133 relative to the base plate 131. When the roller 133 contacts the surface of the battery 300, the inclination angle of the roller 133 relative to the base plate 131 can be adjusted through the angle meter 134, so as to ensure that the surface of the roller 133 can be completely in contact with the surface of the battery 300, and further ensure the dust removal effect of the battery 300.

[0050] In some embodiments, referring to Figure 1 As shown, at least two sets of the roller assemblies 130 are provided, and the two sets of the roller assemblies 130 are arranged oppositely to remove the dust on the opposite two surfaces of the battery 300. Therefore, through the two oppositely arranged roller assemblies 130, the dust on the two opposite surfaces of a battery 300 can be removed simultaneously, improving the dust removal efficiency.

[0051] It can be understood that in this embodiment, the dust removal operation after welding can also be performed on multiple batteries 300 at the same time, and only need to set the paired roller assemblies 130 according to the actual number of batteries 300.

[0052] In some embodiments, referring to Figure 1 and Figure 3As shown, the fixing component 120 includes a first clamp 121 and a second clamp 122. The battery 300 includes at least two relatively arranged first sides. The first clamp 121 and the second clamp 122 are arranged oppositely and can clamp and fix the two first sides of the battery 300. When the battery 300 moves to an appropriate position, the two first sides of the battery 300 are clamped by the first clamp 121 and the second clamp 122, which can ensure the fixation of the battery 300, avoid the displacement of the battery 300 during the movement of the roller 133, and ensure the close contact between the roller 133 and the battery 300, thereby ensuring the dust removal effect of the battery 300.

[0053] In addition, the third clamp 123 and the fourth clamp 124 can play a supplementary role for the first clamp 121 and the second clamp 122, so as to ensure the stability of the battery 300 in four directions through the four clamps, avoid the displacement of the battery 300 during the dust removal process, and ensure the dust removal effect.

[0054] In some embodiments, referring to Figure 1 and Figure 3 As shown, both the first clamp 121 and the second clamp 122 include a second driving member 1211 and a first clamping plate 1212. The first clamping plate 1212 is movably connected to the frame 110. The second driving member 1211 is connected to the first clamping plate 1212 to drive the first clamping plate 1212 to move. Among them, the second driving member 1211 can drive the two first clamping plates 1212 to move towards or away from each other to clamp or release the battery 300 in the direction of the two first sides of the battery 300.

[0055] In this embodiment, when the battery 300 moves between the two first clamping plates 1212, the second driving member 1211 drives the two first clamping plates 1212 to move towards each other to clamp the two first sides of the battery 300. When the dust removal operation of the battery 300 is completed, the second driving member 1211 drives the two first clamping plates 1212 to move away from each other to release the battery 300 in the direction of the two first sides, which is convenient for the battery 300 to continue to move to the next process.

[0056] In some embodiments, referring to Figure 1 and Figure 3As shown, the fixing component 120 further includes a third clamp 123 and a fourth clamp 124. The battery 300 further includes two relatively arranged second sides. The third clamp 123 and the fourth clamp 124 are arranged relatively and can clamp and fix the two second sides of the battery 300. When the battery 300 moves to an appropriate position, the clamping of the two second sides of the battery 300 is realized through the third clamp 123 and the fourth clamp 124, which can ensure the fixation of the battery 300, avoid the displacement of the battery 300 during the movement of the roller 133, and ensure the close contact between the roller 133 and the battery 300, thereby ensuring the dust removal effect of the battery 300.

[0057] In some embodiments, referring to Figure 1 and Figure 3 As shown, at least one of the first clamp 121 and the second clamp 122 is provided with a sensor for detecting the in-place situation of the battery 300.

[0058] By arranging a sensor on the first clamp 121 or the second clamp 122, when the sensor detects that the battery 300 has moved in place, the second driving member 1211 drives the two first clamping plates 1212 to move towards each other to realize the clamping in the direction of the two first sides of the battery 300; when the battery 300 completes the dust removal operation, the second driving member 1211 drives the two first clamping plates 1212 to move away from each other to realize the release in the direction of the two first sides of the battery 300, facilitating the battery 300 to continue to move to the next process.

[0059] In some embodiments, referring to Figure 1 and Figure 3 As shown, at least one of the third clamp 123 and the fourth clamp 124 is provided with a sensor for detecting the in-place situation of the battery 300.

[0060] By arranging a sensor on the third clamp 123 or the fourth clamp 124, when the sensor detects that the battery 300 has moved in place, the third driving member 1231 drives the two second clamping plates 1232 to move towards each other to realize the clamping in the direction of the two second sides of the battery 300; when the battery 300 completes the dust removal operation, the third driving member 1231 drives the two second clamping plates 1232 to move away from each other to realize the release in the direction of the two second sides of the battery 300, facilitating the battery 300 to continue to move to the next process.

[0061] In some embodiments, referring to Figure 1 and Figure 3As shown, both the third fixture 123 and the fourth fixture 124 include a third driving member 1231 and a second clamping plate 1232. The second clamping plate 1232 is movably connected to the frame 110, and the third driving member 1231 is connected to the second clamping plate 1232 to drive the second clamping plate 1232 to move. Among them, the third driving member 1231 can drive the two second clamping plates 1232 to move towards or away from each other, so as to clamp or release the battery 300 in the directions of the two second sides of the battery 300.

[0062] In this embodiment, when the battery 300 moves between the two second clamping plates 1232, the third driving member 1231 is used to drive the two second clamping plates 1232 to move towards each other, so as to clamp the battery 300 in the directions of the two second sides of the battery 300. When the dust removal operation of the battery 300 is completed, the third driving member 1231 is used to drive the two second clamping plates 1232 to move away from each other, so as to release the battery 300 in the directions of the two second sides of the battery 300, which is convenient for the battery 300 to continue to move to the next process.

[0063] It can be understood that in this embodiment, the first fixture 121 and the second fixture 122 respectively clamp the battery 300 in the left-right direction, and the third fixture 123 and the fourth fixture 124 respectively clamp the battery 300 in the up-down direction. Among them, the first fixture 121 is located on the left side of the battery 300, the second fixture 122 is located on the right side of the battery 300, the third fixture 123 is located on the lower side of the battery 300, and the fourth fixture 124 is located on the upper side of the battery 300.

[0064] In some embodiments, referring to Figure 2 As shown, the vacuum adsorption assembly 140 includes an adsorption pipe 141 and a pumping device. The adsorption pipe 141 is arranged on the roller assembly 130. The adsorption pipe 141 is connected to the pumping device and is used to adsorb the dust on the battery 300 and / or the dust around the battery 300. In this embodiment, by using the pumping device to adsorb the dust on the surface and around the battery 300, it can supplement the function of the roller 133, ensure the dust removal effect on the battery 300, and the dust removal effect is good.

[0065] Referring to Figure 4 and Figure 5 As shown, in a second aspect, the present application further provides a dust removal system 1000, which includes a transfer device 200 and the dust removal mechanism 100 described above. The transfer device 200 is used to transfer the battery 300 to the frame 110.

[0066] The independent claim of this dust removal system 1000 has all the beneficial effects of the above dust removal mechanism 100:

[0067] When the battery 300 is welded and transferred to the frame 110 of this embodiment from the previous step, after the battery 300 moves to an appropriate position, the fixing assembly 120 can clamp and fix the battery 300. The roller assembly 130 can move on the frame 110 and roll over the welded edge of the battery 300 to remove the dust on the surface of the battery 300. At the same time, the vacuum adsorption assembly 140 can adsorb the surface dust of the battery 300. Therefore, through the combined action of the roller assembly 130 and the vacuum adsorption assembly 140, while using the roller assembly 130 to stick away the surface debris and residues of the battery 300, the battery 300 will not be damaged. Finally, the debris and residues are sucked away by the vacuum dust removal method, with high roller pressing accuracy, good weld cleaning effect, and high dust removal efficiency.

[0068] In some embodiments, referring to Figure 5 As shown, the transfer device 200 includes a fixing frame 210, a first cover plate 220, and a second cover plate 230. The battery 300 is inserted into the fixing frame 210, and the first cover plate 220 and the second cover plate 230 are rotatably connected to both sides of the fixing frame 210. When the first cover plate 220 and the second cover plate 230 are in the first position, the first cover plate 220 and the second cover plate 230 are both in contact with the battery 300 to lock the battery 300. When the first cover plate 220 and the second cover plate 230 are in the second position, the first cover plate 220 and the second cover plate 230 are both separated from the battery 300 to unlock the battery 300. Therefore, during the process of transferring the battery 300 from the previous step to the dust removal mechanism 100, the first cover plate 220 and the second cover plate 230 remain in contact with the surface of the battery 300, so as to ensure that the battery 300 can be stably transferred to the dust removal mechanism 100 and prevent the battery 300 from being damaged during the transfer process.

[0069] In some embodiments, referring to Figure 4 As shown, the dust removal mechanism 100 further includes a fourth driving member 240 and an unlocking block 250. There are two fourth driving members 240 and two unlocking blocks 250, which are connected one by one. The unlocking block 250 is movably connected to the frame 110. The fourth driving member 240 is connected to the unlocking block 250 to drive the two unlocking blocks 250 to move towards the first cover plate 220 and the second cover plate 230 respectively, so that the first cover plate 220 and the second cover plate 230 both rotate from the first position to the second position.

[0070] It can be understood that in this embodiment, when the battery 300 is transferred from a previous step to the dust removal mechanism 100 by the transfer device 200, both the first cover plate 220 and the second cover plate 230 are in the first position, that is, the battery 300 is in a locked state, which can avoid the detachment of the battery 300 during the transfer process; after the battery 300 is transferred to the dust removal mechanism 100, the unlocking block 250 is driven to move by the fourth driving member 240, so that both the first cover plate 220 and the second cover plate 230 rotate from the first position to the second position, that is, the battery 300 is converted from the locked state to the unlocked state, facilitating the subsequent dust removal operation of the battery 300.

[0071] In some embodiments, referring to Figure 4 As shown, a sensor for detecting the in-place situation of the battery 300 is provided on the unlocking block 250. When the sensor detects that the battery 300 has moved in place, it can drive the fourth driving member 240, so that the fourth driving member 240 drives the unlocking block 250 to move, thereby causing both the first cover plate 220 and the second cover plate 230 to rotate from the first position to the second position, that is, causing the battery 300 to be converted from the locked state to the unlocked state, with a high degree of automation and also capable of improving the dust removal efficiency.

[0072] In summary, in this embodiment, the battery 300 is transferred on the transfer device 200 to the rack 110. When the battery 300 reaches between the first fixture 121 and the second fixture 122, the sensor detects that the battery 300 is in place. At this time, the fourth driving member 240 drives the unlocking block 250 to move, so that both the first cover plate 220 and the second cover plate 230 rotate from the first position to the second position, causing the battery 300 to be converted to the unlocked state; the third driving member 1231 of the third fixture 123 drives the second clamping plate 1232 to extend upward and jacks up the battery 300 by a fixed distance, and the fourth driving member 240 of the fourth fixture 124 drives the second clamping plate 1232 to extend downward by a fixed distance and presses the battery 300 downward; the first clamping plates 1212 of the first fixture 121 and the second fixture 122 move towards each other to achieve the locking of the battery 300 in the left-right direction, clamping the battery 300 so that the battery 300 is fixed and does not shake.

[0073] After the battery 300 is fixed, under the action of the first driving member 132, the roller 133 is driven to move and move along the welded edge of the cover plate and the side aluminum shell of the battery 300, and the inclination angle of the roller 133 is controlled by the angle gauge 134 to ensure the fitting of the roller 133 with the welded edge. The roller 133 rolls over the welded edge to stick away dust and cooperate with the suction pipe to suck away welding slag.

[0074] After dust removal, the roller 133 is retracted by the first driving member 132, and the first fixture 121 and the second fixture 122 move away from each other, and the third fixture 123 and the fourth fixture 124 move away from each other to release the battery 300; the fourth driving member 240 drives the unlocking block 250 to move, so that both the first cover plate 220 and the second cover plate 230 rotate from the second position to the first position, converting the battery 300 into a locked state. The battery 300 can be fixed on the mobile device and transferred to the next station along with the mobile device, completing the dust removal operation of the battery 300.

[0075] Thus, by using the dust removal system 1000 of this embodiment, the positions of the battery 300 and the roller 133 can be accurately positioned. While the roller 133 rolls the debris and residues on the weld of the battery 300, the battery 300 will not be damaged. Finally, the debris and residues are sucked away by vacuum dust removal, with high rolling accuracy, clean welds, and high working efficiency.

[0076] The embodiments of the present invention have been introduced in detail above. Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention. The descriptions of the above embodiments are 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.
