[0053] Reference Figure 1 and Figure 2 The battery welding positioning dust removal device according to the embodiment of the present invention includes a first dust removal module 1, a second dust removal module 2, a module driving component 6 and an air blowing dust removal module 242.

[0054] The first dust removal module 1 includes a frame 11 , a first driving assembly 12 and a first positioning dust removal assembly 13 . The first positioning dust removal assembly 13 is slidably disposed on the frame 11 , and the first driving assembly 12 is connected to the first positioning dust removal assembly 13 .

[0055] The second dust removal module 2 includes a base 26, a second positioning dust removal assembly and a driving device; the second positioning dust removal assembly is slidably connected to the base 26, and the second positioning dust removal assembly and the first positioning dust removal assembly 13 can be mutually enclosed to form an accommodating cavity; the driving device is connected to the second positioning dust removal assembly, and the driving device and the first driving assembly 12 are used to drive the first positioning dust removal assembly 13 and the second positioning dust removal assembly to move closer to or away from the middle of the accommodating cavity.

[0056] The air blowing dust removal module 242 includes a plurality of air blowing dust removal components, and the plurality of air blowing dust removal components are respectively arranged on the first positioning dust removal component 13 and the second positioning dust removal component, and the air blowing dust removal components each include a dust removal device 2423 and an air blowing device 2422 .

[0057] The module driving assembly 6 is used to drive the first dust removal module 1 and the second dust removal module 2 to move closer to or away from each other.

[0058] When the battery moves between the first dust removal module 1 and the second dust removal module, the module driving component first drives the first dust removal module 1 and the second dust removal module 2 to approach each other, and makes the second dust removal module 2 and the first dust removal module 1 surround each other to form an accommodating chamber. At this time, the battery is located in the accommodating chamber, and then the first driving component 12 and the driving device respectively drive the first positioning dust removal component 13 and the second positioning dust removal component to approach the middle of the accommodating chamber, so that the first positioning dust removal component 13 and the second positioning dust removal component clamp the battery on all sides, thereby positioning the battery to ensure the accuracy of the welding process; at the same time, since the first positioning dust removal component 13 and the second positioning dust removal component are both provided with an air blowing dust removal module 242, with the help of the dust removal device 2423 and the air blowing device 2422, the dust and welding slag generated during welding can be removed during welding, and protective gas is provided to protect the battery, thereby further reducing the impact on welding to improve the welding yield rate.

[0059] In some embodiments of the present invention, specifically, the module driving assembly 6 is used to drive the second dust removal module 2 to move closer to or away from the first dust removal module 1; of course, according to actual conditions, in some other embodiments of the present invention, it is also possible to choose to drive the first dust removal module 1 to move, or to drive the first dust removal module 1 and the second dust removal module 2 to move together at the same time.

[0060] In some examples of the present invention, the first driving component 12 includes a first cylinder 121 and a first guide block 122; the first guide block 122 is slidably connected to the frame 11, and the first cylinder 121 is used to drive the first guide block 122 to slide. The first positioning and dust removal component 13 is provided with a first roller 133, and the first roller 133 is tangent to the first guide block 122, and a protrusion is provided on the side of the first guide block 122 tangent to the first roller 133.

[0061] For example, refer to Figure 2, the first cylinder 121 and the first guide block 122 are arranged along the Y-axis direction, and the first cylinder 121 drives the first guide block 122 to reciprocate in the Y-axis direction. A first slide rail assembly 123 is arranged on the frame 11 along the X-axis direction, and the first positioning dust removal assembly 13 is slidably arranged on the first slide rail assembly 123; a first roller 133 is arranged on the bottom surface of the first positioning dust removal assembly 13, and the first roller 133 is tangent to the first guide block 122, and a protrusion is arranged on the side of the first guide block 122 tangent to the first roller 133. When the first cylinder 121 drives the first guide block 122 to move in the Y-axis direction, the protrusion on the side of the first guide block 122 tangent to the first roller 133 pushes the first roller 133 to move in the X-axis direction, thereby indirectly pushing the first positioning dust removal assembly 13 to slide on the first slide rail assembly 123 to approach the accommodating cavity. In addition, a first reset device 14 is provided between the frame 11 and the first positioning dust removal assembly 13. The first reset device 14 can be selected from elastic parts such as springs. When the first cylinder 121 drives the first guide block 122 to return to its original position, the first guide block 122 cannot drive the first roller 133 to move on the X-axis, and cannot drive the first positioning dust removal assembly 13 to move on the X-axis. Therefore, the first reset device 14 is required to pop out the first positioning dust removal assembly 13 to ensure that the first roller 133 is always close to the first guide block 122.

[0062] In some examples of the present invention, the first positioning dust removal component 13 includes a first connecting plate 131, the air blowing dust removal module 242 includes a first air blowing dust removal component 132, the first air blowing dust removal component 132 is slidably connected to the first connecting plate 131 along the Y-axis, the first positioning dust removal component 13 is slidably connected to the frame 11 along the X-axis, and a first fine-tuning device 1311 is provided on the first connecting plate 131, and the first fine-tuning device 1311 is used to adjust the Y-axis position of the first air blowing dust removal component 132.

[0063] For example, refer to Figure 2, a second slide rail assembly 1312 is arranged on the top surface of the first connecting plate 131 along the Y-axis direction; the first air blowing and dust removal assembly 132 is slidably connected to the first connecting plate 131 through the second slide rail assembly 1312. The first fine-tuning device 1311 is arranged on the first connecting plate 131, and includes a first protrusion 13111, a second protrusion 13112, a first adjusting bolt 13113, a first elastic member 13114 and a first abutting block 13115. The first protrusion 13111 and the second protrusion 13112 are arranged on the first connecting plate 131, the first adjusting bolt 13113 is arranged on the first protrusion 13111, the first elastic member 13114 is arranged on the second protrusion 13112, and the first abutting block 13115 is arranged on the bottom surface of the first air blowing and dust removal assembly 132, and abuts against the first adjusting bolt 13113 and the first elastic member 13114 respectively. The first adjusting bolt 13113 is rotated and adjusted so that the first adjusting bolt 13113 pushes the first abutting block 13115 to compress the first elastic member 13114, thereby adjusting the Y-axis position of the first air blowing dust removal assembly 132 on the second slide rail assembly 1312. When the first driving assembly 12 drives the first positioning dust removal assembly 13 to approach the battery to be welded in the accommodating cavity, if the first positioning dust removal assembly 13 is slightly misaligned on the Y-axis relative to the welding edge of the battery to be welded, the first fine-tuning device 1311 can be adjusted to ensure accurate positioning.

[0064] In some embodiments of the present invention, the second positioning dust removal assembly includes a first short side positioning dust removal assembly 21, a second short side positioning dust removal assembly 22 and a long side positioning dust removal assembly 23, and they are arranged in a U shape, and the first positioning dust removal assembly 13 is directly opposite to the position of the U-shaped opening. Figure 1 and Figure 2 In this embodiment, for a rectangular battery, the first short-side positioning dust removal component 21, the second short-side positioning dust removal component 22 and the long-side positioning dust removal component 23 correspond to the two short sides of the rectangular battery and the long side sandwiched between the two short sides respectively; the second positioning dust removal component is driven by the module driving component 6 to approach the battery to be welded, and can cover the three welding edges of the welded battery at one time; the first positioning dust removal component 13 is driven by the first driving device 12 to approach the battery to be welded, so as to seal the U-shaped opening and position the battery to be welded in the accommodating cavity.

[0065] In some examples of the present invention, the second short side positioning dust removal assembly 22 includes a second cylinder 221, a second guide block 222, a sliding plate 241 and a second roller 223, the sliding plate 241 is slidably connected to the base 26, the air blowing dust removal module 242 includes a second air blowing dust removal assembly, the second air blowing dust removal assembly and the second roller 223 are arranged on the sliding plate 241, the second cylinder 221 is used to drive the second guide block 222 to slide, the second roller 223 is tangent to the second guide block 222, and a protrusion is arranged on the side where the second guide block 222 is tangent to the second roller 223.

[0066] For example, refer to Figure 4 , the second cylinder 221 and the second guide block 222 are arranged along the X-axis direction; the second cylinder 221 drives the second guide block 222 to reciprocate in the X-axis direction. A third slide rail assembly 224 is arranged on the base 26 along the Y-axis direction, and the sliding plate 241 is slidably connected to the third slide rail assembly 224. A second roller 223 is arranged on the sliding plate 241, and the second roller 223 is tangent to the second guide block 222. A protrusion is arranged on the side of the second guide block 222 that is tangent to the second roller 223. When the second cylinder 221 pushes the second guide block 222 to move in the X-axis direction, the protrusion of the second guide block 222 pushes the second roller 223 to move in the Y-axis direction, and then indirectly pushes the sliding plate 241 to slide on the third slide rail assembly 224, so that the second air blowing dust removal assembly is close to the accommodating chamber; the second cylinder 221 and the second guide block 222 are arranged along the X-axis direction, which can save installation space. A second reset device 226 is also provided between the sliding plate 241 and the base 26. The second reset device 226 is provided along the Y-axis direction. The second reset device 226 can be selected from elastic members such as springs. When the second cylinder 221 drives the second guide block 222 to return to its original position, the second guide block 222 cannot drive the second roller 223 to move on the X-axis, and thus cannot drive the sliding plate 241 to move on the X-axis. Therefore, the second reset device 226 is required to eject the sliding plate 241 to ensure that the second roller 223 is always in close contact with the second guide block 222 to ensure the accuracy of the movement. In addition, a third roller 225 is also provided on the base 26. The third roller 225 is in close contact with the long straight edge of the second guide block 222 to ensure that when the second cylinder 221 pushes the second guide block 222 to move, the direction of the second guide block 222 will not deviate to ensure the accuracy of the movement.

[0067] In some embodiments of the present invention, the second positioning dust removal assembly includes a sliding plate 241, and is slidably connected to the base 26 through the sliding plate 241. The sliding plate 241 is provided with a positioning block 244 and a micrometer 245. The micrometer 245 is connected to the positioning block 244 and is used to fine-tune the position of the positioning block 244. Figure 4 In this embodiment, when the positioning block 244 is not parallel to the welding edge of the battery to be welded, the micrometer 245 can be rotated to adjust the positioning block 244 to ensure that the positioning block 244 and the welding edge of the battery to be welded are parallel to each other.

[0068] In some examples of the present invention, the air blowing dust removal module 242 of the first short side positioning dust removal assembly 21 includes a fourth air blowing dust removal assembly, which is arranged on the sliding plate 241, and a cylinder driving device is arranged at one end of the sliding plate 241 away from the accommodating chamber, and the cylinder driving device pushes the sliding plate 241 to approach or move away from the accommodating chamber. The air blowing dust removal module 242 of the long side positioning dust removal assembly 23 includes a third air blowing dust removal assembly, which is arranged on the sliding plate 241, and a cylinder driving device is arranged at one end of the sliding plate 241 away from the accommodating chamber, and the cylinder driving device pushes the sliding plate 241 to approach or move away from the accommodating chamber.

[0069] In some examples of the present invention, the blowing device 2422 includes an air intake pipe and an air intake plate, wherein the air intake pipe connects the air intake plate and an external air source, and the air intake plate is provided with an air blowing port on the side facing the accommodating cavity; the dust removal device 2423 includes a dust removal pipe and an air suction plate, wherein the dust removal pipe connects the air suction plate and an external negative pressure generating device, and the air suction plate is provided with a dust suction port on the side facing the accommodating cavity.

[0070] In some embodiments of the present invention, the module driving assembly 6 includes a moving plate 62 and a horizontal driving module 61 driving the moving plate 62 to slide along the X-axis, the base 26 is connected to the moving plate 62 along the Y-axis, and a second fine-tuning device 27 is provided between the moving plate 62 and the second dust removal module, and the second fine-tuning device 27 is used to adjust the Y-axis position of the second dust removal module. Figure 3 and Figure 5 A fourth slide rail assembly 25 is arranged on the moving plate 62 along the Y-axis direction, and the base 26 is slidably connected to the fourth slide rail assembly 25; the second fine-tuning device 27 connects the base 26 and the moving plate 62, and can fine-tune the Y-axis position of the base 26 on the fourth slide rail assembly 25. When the module driving assembly 6 drives the second dust removal module 2 to approach the battery to be welded, if the second dust removal module 2 as a whole is slightly misaligned relative to the battery to be welded, the second fine-tuning device 27 can be used to adjust the position of the second dust removal module 2 as a whole relative to the battery to be welded.

[0071] In some embodiments of the present invention, the second fine-tuning device 27 includes a second adjusting bolt 273, a second elastic member 274, two first fixing blocks 271 and two second fixing blocks 272, wherein the two first fixing blocks 271 are fixedly connected to the base 26, the two second fixing blocks 272 are fixedly connected to the moving plate 62, the second adjusting bolt 273 is threadedly connected to one of the first fixing blocks 272, and one end of the second adjusting bolt 273 abuts against one of the second fixing blocks 271, and the two ends of the second elastic member 274 abut against another first fixing block 272 and another second fixing block 271, respectively. Figure 3By simply rotating the second adjusting bolt 273, the second dust removal module 2 can be driven to move along the Y-axis as a whole, thereby achieving fine adjustment of the second dust removal module 2 on the Y-axis, wherein the maximum adjustable distance is equal to the maximum deformation compression range of the second elastic member 274.
