Description

Dust removal device Technical Field

[0001] The present application relates to the technical field of dust removal, and more specifically, to a dust removal device. Background Art

[0002] Pre-spot welding is a key step in the production of blade batteries. After the battery is compressed using a jig, lasers are used to pre-spot weld the blade battery's four edges. This process involves rotating the battery while welding, completing the spot welding of all four edges. During the welding process, dust and debris are easily deposited on the battery surface. Failure to clean the battery promptly can compromise battery quality.

[0003] The current dust removal mechanism typically extends the dust removal head after the battery is rotated to one side, then descends a preset distance and approaches the battery shell opening to remove dust. After welding, the dust removal head retracts to its initial position. The battery is then rotated to the other side, and the dust removal head repeats its extension and dust removal process, then retracts again, until the welding cycle is complete. This dust removal method not only affects dust removal efficiency and significantly reduces the timing of the workstation, but also affects the dust removal effect, resulting in suboptimal dust removal results, resulting in residual welding slag on the jig, and affecting subsequent welding results.

[0030] The dust removal device 100 according to an embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0031] As shown in Figures 1 to 3, the dust removal device 100 according to an embodiment of the present application includes a fixed dust removal pipe 10, a follow-up dust removal pipe 20, a connecting assembly 30 and a dust suction pipe 40.

[0033] In other words, the dust removal device 100 according to the embodiment of the present application can be used to perform real-time dust removal on the part to be dusted 200. The part to be dusted 200 can be a battery that needs to be welded. When the part to be dusted 200 is welded, it needs to be rotated to adjust the welding position. The dust removal device 100 can move synchronously with the part to be dusted 200, thereby performing real-time dust removal on it when the part to be dusted 200 is welded.

[0034] The dust removal device 100 according to the embodiment of the present application can be mainly composed of a fixed dust removal pipe 10, a follower dust removal pipe 20, a connecting assembly 30 and a dust suction pipe 40, wherein the fixed dust removal pipe 10 is formed as a fixed pipeline connected to the negative pressure interface of the negative pressure generating device. The fixed dust removal pipe 10 is fixedly arranged to ensure the stability of the connection with the negative pressure interface. The follower dust removal pipe 20 is movably connected to the fixed dust removal pipe 10, that is, the follower dust removal pipe 20 is rotatable relative to the fixed dust removal pipe 10, so that the follower dust removal pipe 20 can move synchronously with the dust removal part 200 along with the connecting assembly 30.

[0035] The connecting assembly 30 is provided on the follow-up dust removal pipe 20 and can be fixedly connected to the follow-up dust removal pipe 20. The connecting assembly 30 is simultaneously matched with the dust-removed part 200 and can move synchronously with the dust-removed part 200, thereby driving the follow-up dust removal pipe 20 connected thereto to move synchronously. There are many ways for the connecting assembly 30 to cooperate with the dust-removed part 200, as long as the connecting assembly 30 is matched with the dust-removed part 200 and can move synchronously with the dust-removed part 200. The dust suction pipe 40 can be provided on the connecting assembly 30, and the dust suction pipe 40 moves synchronously with the connecting assembly 30. One end of the dust suction pipe 40 with an air outlet 42 is connected to the fixed dust removal pipe 10 through the connecting assembly 30 or the follow-up dust removal pipe 20, thereby achieving connection with the negative pressure interface. The air intake 41 of the dust suction pipe 40 is close to the position where the dust-removed part 200 is assembled, so that when the dust-removed part 200 is welded, the welding position thereof can be suctioned and dusted in real time.

[0036] Therefore, according to the dust removal device 100 of the embodiment of the present application, by providing a fixed dust removal pipe 10 that can be connected to the negative pressure interface and a follow-up dust removal pipe 20 that can rotate relative to the fixed dust removal pipe 10, the fixed dust removal pipe 10 can be used to connect the dust removal device to the negative pressure interface, and the follow-up dust removal pipe 20 can cooperate with the connecting component 30 to rotate synchronously with the dust removal part 200, so that the dust suction pipe 40 can dust the dust removal part 200 in real time, effectively improving the dust removal efficiency and ensuring the dust removal effect.

[0037] According to one embodiment of the present application, the follow-up dust removal pipe 20 is coaxially arranged with the second end of the fixed dust removal pipe 10 , and the follow-up dust removal pipe 20 is sleeved on the second end of the fixed dust removal pipe 10 .

[0038] Specifically, as shown in Figures 1 and 2, in this embodiment, the fixed dust removal pipe 10 can be formed into a long tube structure to meet the connection requirements with the negative pressure interface and the assembly requirements with the follow-up dust removal pipe 20. The follow-up dust removal pipe 20 can be formed into a hollow columnar structure, and its length can be reasonably selected according to actual needs. The follow-up dust removal pipe 20 is mounted on the fixed dust removal pipe 10 and can rotate around the fixed dust removal pipe 10.

[0039] Therefore, on the basis of realizing the movable connection between the follow-up dust removal pipe 20 and the fixed dust removal pipe 10, the structure is easy to assemble and simple to operate.

The outer ring of the bearing 50 abuts against the follow-up dust removal tube 20, and the inner ring of the bearing 50 is assembled on the fixed dust removal tube 10. The seal 60 is arranged between the follow-up dust removal tube 20 and the fixed dust removal tube 10, and can be used to seal the gap between the follow-up dust removal tube 20 and the fixed dust removal tube 10. On the basis of ensuring that the follow-up dust removal tube 20 and the fixed dust removal tube 10 can rotate relative to each other, the air tightness between the follow-up dust removal tube 20 and the fixed dust removal tube 10 can also be ensured.

[0043] According to one embodiment of the present application, there are two bearings 50, and the two bearings 50 are arranged at both ends of the follow-up dust removal pipe 20 at intervals along the axial direction of the follow-up dust removal pipe 20, and the seal 60 is arranged between one bearing 50 and the connecting assembly 30.

[0044] Therefore, by arranging bearings 50 at both ends of the follow-up dust removal pipe 20, the follow-up dust removal pipe 20 can be effectively supported, and the seal 60 is arranged at one end of the follow-up dust removal pipe 20 close to the connecting assembly 30, which can effectively prevent air leakage between the follow-up dust removal pipe 20 and the fixed dust removal pipe 10.

[0045] Furthermore, a transition chamber connected to the fixed dust collection pipe 10 is defined between the connecting assembly 30, the inner wall of the mobile dust collection pipe 20, the outer wall of the fixed dust collection pipe 10, and the seal 60. An air outlet 42 is provided in the connecting assembly 30 and communicates with the transition chamber. The connecting assembly 30 seals the open end of the mobile dust collection pipe 20 but remains unconnected to the fixed dust collection pipe 10, allowing the connecting assembly 30 and the mobile dust collection pipe 20 to rotate. Furthermore, the enclosed transition chamber communicates with the fixed dust collection pipe 10. The connecting assembly 30 is provided with a through hole connected to the transition chamber, and the air outlet 42 of the dust collection pipe 40 is connected to this through hole. Clearly, the air outlet 42 communicates with the fixed dust collection pipe 10 via the connecting assembly 30. Of course, the mobile dust collection pipe 20 can also be provided with a through hole connected to the transition chamber, and the air outlet 42 of the dust collection pipe 40 can also be connected to the through hole in the mobile dust collection pipe 20, thereby achieving communication with the transition chamber and the fixed dust collection pipe 10.

[0046] In some specific embodiments of the present application, the connection assembly 30 includes: a connection plate 31 , a support member 32 and a fixing plate 33 .

[0047] Specifically, the connecting plate 31 is connected to the follow-up dust removal pipe 20 and moves synchronously with the follow-up dust removal pipe 20, the dust suction pipe 40 is arranged on the connecting plate 31, the first end of the support member 32 is connected to the connecting plate 31, the fixed plate 33 is arranged at the second end of the support member 32, the fixed plate 33 is suitable for connecting to the dust removal part 200, and the air intake 41 is arranged close to the fixed plate 33.

[0048] As shown in Figures 1 and 2, in this embodiment, the connecting assembly 30 can be composed of a connecting plate 31, a support member 32, and a fixed plate 33, wherein the connecting plate 31 is fixedly connected to the follow-up dust removal pipe 20, and the support member 32 and the fixed plate 33 both achieve synchronous movement with the follow-up dust removal pipe 20 through the connecting plate 31. The connecting plate 31 is provided with a through hole that communicates with the fixed dust removal pipe 10, and the air outlet 42 of the dust suction pipe 40 is connected to the fixed dust removal pipe 10 through the through hole. The fixed plate 33 is used to cooperate with the dust removal part 200 to achieve synchronous movement with the dust removal part 200, and the support member 32 can connect the fixed plate 33 and the connecting plate 31, thereby achieving synchronous movement of the dust removal part 200 and the connecting plate 31.

[0049] Therefore, this structure can realize the connection between the dust-removed part 200 and the follow-up dust-removal pipe 20, and after the two are connected, the dust-removed part 200 can drive the follow-up dust-removal pipe 20 to move synchronously, thereby realizing real-time dust removal of the dust-removed part 200.

[0050] Optionally, according to some embodiments of the present application, there are two support members 32 , the two support members 32 are arranged opposite to each other, and the dust suction pipe 40 is arranged between the two support members 32 .

[0051] Specifically, the connecting plate 31 can be formed into a circular or other shaped plate structure, and the two support members 32 can be provided on opposite sides of the same side of the connecting plate 31, and the fixed plate 32 is connected to the connecting plate 31 via the two support members 32. Thus, this structure can ensure the stability of the connection between the dust removal part 200 and the follower dust removal pipe 20.

[0052] In some specific embodiments of the present application, the dust suction pipe 40 includes an upper pipe body 43 and a lower pipe body 44 .

[0055] That is, the dust suction pipe 40 is a single tube structure, or it can be composed of multiple tubes, such as an upper tube 43 and a lower tube 44. As shown in Figures 1 and 3, the upper tube 43 and the lower tube 44 are respectively provided with an air intake 41, and the air intake 41 is provided on opposite sides of the dust removal part 200.

[0057] According to some embodiments of the present application, the air inlet 41 of the upper tube 43 and the air inlet 41 of the lower tube 44 are respectively extended obliquely toward a position suitable for installing the dust removal part 200.
