Description

Technical Field

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

[0002] In the production process of blade batteries, the pre-spot welding process is one of the key processes. Generally, after the battery is pressed by a fixture, a laser is used to pre-spot weld the blade battery around the edges. The spot welding is completed while rotating the blade battery. During the welding process, dust and debris are easily generated and fall on the surface of the battery. If not cleaned in time, it will affect the quality of the battery.

[0003] The dust removal mechanism currently used usually extends the dust removal head after the battery rotates one side, descends a preset distance, and then approaches the battery shell opening for dust removal. After welding, it retracts to the initial position, and then rotates the battery to the other side. The dust removal head repeatedly extends to remove dust, and then retracts until the welding is completed. This dust removal method not only affects the dust removal efficiency and greatly reduces the timing of the workstation, but also affects the dust removal effect, making the dust removal effect unsatisfactory, resulting in welding slag remaining on the fixture, affecting the subsequent welding effect.

[0036] In other words, the dust removal device 100 according to the embodiment of the utility model can be used to perform real-time dust removal on the part 200 to be dust removed. The part 200 to be dust removed can be a battery that needs to be welded. When the part 200 to be dust removed is welded, it needs to be rotated to adjust the welding position. The dust removal device 200 can move synchronously with the part 200 to be dust removed, so as to perform real-time dust removal on the part 200 to be dust removed when it is welded.

[0037] The dust removal device 100 according to the embodiment of the utility model 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, and the fixed dust removal pipe 10 is fixedly arranged to ensure the connection stability with the negative pressure interface.

[0051] 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.

[0052] Optionally, according to some embodiments of the present invention, 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 .
