Description

Technical Field

[0001] The present application relates to the technical field of battery production, and in particular to a dust collection device and a battery production jig. Background Art

[0002] Laser welding uses high-energy laser pulses to locally heat a small area of ​​the material. The energy of the laser radiation diffuses into the material through heat conduction, melting the material to form a specific molten pool. Auxiliary shielding gas is a key process in laser welding. On the one hand, it is to prevent the metal material from sputtering and contaminating the focusing lens; on the other hand, it is to prevent the plasma generated during the welding process from being over-focused and blocking the laser from reaching the material surface.

[0003] There are three common ways to control welding fumes: overall workshop ventilation, welding station ventilation, and welding area ventilation. The welding area ventilation method integrates the welding gun and the absorption tube together. When welding, the absorption tube can absorb the smoke before it overflows, so the overall smoke absorption effect is better. However, the protective gas is usually blown from one or both sides during welding. The quality of the products welded by this method cannot be guaranteed. Usually, one side will turn white and the other side will turn black, or both sides will turn white and the middle will turn black, which affects the quality of the battery after welding. In addition, the general dust suction structure is directly fixed by bolts or clamps, so it is impossible to flexibly adjust the dust suction angle, resulting in incomplete absorption of smoke, increasing its production cost and reducing production efficiency.

[0047] The blowing assembly 110 is used to perform annular blowing on the welding part of the battery 101 to prevent oxidation of the welding part of the battery 101. Specifically, the dust collecting assembly 120 is arranged on a side of the blowing assembly 110 away from the battery 101.

[0048] The dust suction assembly 120 includes a first adjusting portion 122 and a first dust suction portion 123 , and the first dust suction portion 123 is installed on the first adjusting portion 122 .

[0050] In the related art, the shielding gas is usually blown from one or both sides during welding. The quality of the product produced by this method of blowing to assist welding cannot be guaranteed. Usually, one side will be white and the other side will be black, or both sides will be white and the middle will be black, which affects the quality of the battery after welding. In addition, the general dust suction structure is directly fixed by bolts or clamps, so it is impossible to flexibly adjust its dust suction angle, resulting in incomplete absorption of smoke, increasing its production cost and reducing production efficiency.

[0051] In this embodiment, the dust suction device 100 includes a blowing assembly 110 and a dust suction assembly 120. In this embodiment, the blowing assembly 110 performs annular blowing on the welding part of the battery 101, thereby improving the quality of the battery 101 after welding the sealing nail 102. In addition, in this embodiment, the first dust suction part 123 is adjusted to adjust the dust suction angle by the first adjustment part 122, so that the first dust suction part 123 can fully absorb the smoke or dust generated when welding the sealing nail 102, thereby reducing its production cost and improving the productivity of the battery 101.

[0052] Alternatively, if Figure 3 As shown, the dust suction assembly 120 further includes a support portion 121 . The support portion 121 is disposed on a side of the dust suction assembly 120 close to the blowing assembly 110 . The support portion 121 has a first through hole 126 .

[0055] like Figure 4 As shown, the support portion 121 includes a first support plate 1211 and a second support plate 1212 .

[0056] The first support plate 1211 is disposed on a side of the support portion 121 close to the blowing assembly 110 , and the first support plate 1211 is used to support the first adjusting portion 122 and the first dust collecting portion 123 .

[0057] Among them, Figure 6 As shown, the first support plate 1211 has a first through hole 126 . In this embodiment, the smoke or dust generated when the battery 101 is welded can reach the first dust suction part 123 from the first through hole 126 , so that the smoke or dust is sucked away by the first dust suction part 123 .

[0058] In addition, the second support plate 1212 is disposed on a side of the first support plate 1211 away from the blowing assembly 110 , and the second support plate 1212 is located on one side of the first support plate 1211 , and the second support plate 1212 is used to install the entire dust collection assembly 120 on an external device.

[0062] Specifically, the first adjustment seat is disposed on a side of the first support plate 1211 away from the blowing assembly 110 , and the second adjustment seat is also disposed on a side of the first support plate 1211 away from the blowing assembly 110 .

[0063] The first adjustment seat and the first support plate 1211 are connected to each other in a relatively slidable manner, that is, the first adjustment seat can slide on the first support plate 1211 in a direction parallel to the first support plate 1211 .

[0064] When the first adjustment seat slides on the first support plate 1211, the first adjustment seat can drive the second adjustment seat and the first dust suction part 123 to move in a direction parallel to the first support plate 1211, thereby realizing the position adjustment of the first dust suction part 123 in a direction parallel to the first support plate 1211.

[0065] Alternatively, if Figure 4 and Figure 5 As shown, the first adjustment seat includes a first adjustment plate 1221 and a second adjustment plate 1222 .

[0067] Optionally, the first adjustment hole 1221a is, for example, an oblong hole, and the axis of the first adjustment hole 1221a is perpendicular to the first support plate 1211, and in this embodiment, when the first adjustment plate 1221 slides on the first support plate 1211, the first adjustment plate 1221 slides along the length direction of the oblong hole.

[0068] In this embodiment, when the first adjustment plate 1221 slides to a suitable position, the first adjustment plate 1221 can be fixed on the first support plate 1211 by means of locking screws passing through the first adjustment holes 1221a.

[0069] Optionally, when the first support plate 1211 is placed horizontally, when the first adjustment plate 1221 slides in the horizontal direction on the first support plate 1211, the first dust suction part 123 can be driven to slide in the horizontal direction relative to the first support plate 1211, thereby realizing the sliding adjustment of the first dust suction part 123 forward, backward, left or right relative to the first support plate 1211, thereby improving the flexibility of the dust suction device 100 described in this embodiment.

[0070] Optionally, the second adjustment plate 1222 is disposed at one end of the first adjustment plate 1221 close to the second adjustment seat. The second adjustment seat and the second adjustment plate 1222 are rotatably connected.

[0071] Specifically, the second adjustment seat is connected to the second adjustment plate 1222 via a locking screw, that is, the second adjustment seat can rotate around the locking screw.

[0072] Alternatively, if Figure 6 As shown, the second adjustment plate 1222 has a second adjustment hole 1222 a , which is, for example, an arc-shaped hole, and an axis of the second adjustment hole 1222 a is parallel to the first support plate 1211 .

[0073] In this embodiment, when the second adjustment seat rotates relative to the second adjustment plate 1222 , the second adjustment seat can drive the first dust suction part 123 to rotate, thereby achieving the adjustment of the dust suction angle of the first dust suction part 123 .

[0074] When the second adjustment seat is rotated to a certain angle on the second adjustment plate 1222, for example, a locking screw is used to pass through the second adjustment hole 1222a to fix the second adjustment seat and the second adjustment plate 1222, so that the first dust suction part 123 can maintain the adjusted angle to perform dust suction work, thereby improving the dust suction flexibility of the dust suction device 100 described in this embodiment.

[0075] Alternatively, if Figure 4 and Figure 5 As shown, the second adjustment seat includes a third adjustment plate 1223 and a fourth adjustment plate 1224 .

[0076] The third adjustment plate 1223 is disposed on a side of the second adjustment plate 1222 away from the first adjustment plate 1221 .

[0077] Specifically, the third adjustment plate 1223 is rotatably connected to the second adjustment plate 1222. Figure 3 As shown, the third adjustment plate 1223 has a third adjustment hole 1223a, and the axis of the third adjustment hole 1223a is parallel to the axis of the second adjustment hole 1222a.

[0078] Optionally, in this embodiment, the dust suction angle of the first dust suction part 123 is adjusted by the third adjustment plate 1223 .

[0079] Specifically, the third adjustment plate 1223 is connected to the second adjustment plate 1222 by a locking screw, and the third adjustment plate 1223 rotates around the locking screw, thereby driving the entire first adjustment part 122 to rotate, thereby realizing the adjustment of the dust suction angle of the first dust suction part 123, that is, realizing the rotatable function of the first dust suction part 123.

[0080] In this embodiment, when the third adjustment plate 1223 is rotated to a certain angle on the second adjustment plate 1222 and needs to be fixed to the second adjustment plate 1222, for example, a locking screw can be used to pass through the second adjustment hole 1222a and the third adjustment hole 1223a in sequence to fix the third adjustment plate 1223 to the second adjustment plate 1222, thereby fixing the entire first adjustment part 122 at the rotated angle, so that the first dust suction part 123 can maintain the adjusted angle for dust suction work, thereby improving the dust suction flexibility of the dust suction device 100 described in this embodiment.
