Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0053] Please refer to Figure 1 and Figure 2The laser processing device provided in the embodiments of the present application can be used in the welding process of a battery. The laser processing device comprises a rack 200, a laser processing head 300, and two or more dust removal mechanisms 100, for example, two or more dust removal mechanisms 100.

[0054] The laser processing head 300 is movably mounted on the rack 200 in a first direction to process workpieces located at different processing stations (not shown in the figure).

[0055] Each dust removal mechanism 100 comprises a dust removal cover 10 and a dust removal pipe 20. One end of the dust removal pipe 20 is in communication with the dust removal cover 10, and the other end is in communication with an external negative pressure device (not shown in the figure). The dust removal cover 10 of each dust removal mechanism 100 is arranged on the rack 200 and corresponds to each processing station. When the laser processing head 300 processes the workpiece of the processing station, the corresponding dust removal cover 10 can suck away the dust to avoid the pollution of the workpiece by the dust. The dust removal pipe 20 is a hard pipe. Specifically, the hard pipe can be a stainless steel pipe. By arranging the dust removal pipe 20 as a hard pipe, the dust removal pipe 20 made of hard material can reduce dust accumulation, improve dust removal effect, and is not easy to break.

[0056] In the embodiments of the present application, Figure 1 the first direction can be represented by the X-axis, the second direction can be represented by the Z-axis, and the third direction can be represented by the Y-axis.

[0057] The laser processing device provided in the embodiments of the present application is movably mounted on the rack 200 by the laser processing head 300, can process workpieces at different processing stations, and is arranged in cooperation with two or more dust removal mechanisms 100. Each dust removal mechanism 100 comprises a dust removal cover 10 and a dust removal pipe 20. The dust removal cover 10 is arranged on the rack 200 and corresponds to each processing station, so that each dust removal cover 10 can suck away the dust generated at the corresponding processing station. The dust removal pipe 20 can be a hard pipe. Compared with the related art which arranges the dust removal cover on the laser processing head 300 and uses a soft pipe to suck dust, the dust accumulation can be reduced, the dust removal effect can be improved, and the hard pipe is not easy to break.

[0058] Referring to Figures 3-4 , the dust removal mechanism 100 can further comprise a dust removal switching assembly 30, which comprises a sealing piece 31 and a driving piece 32. The sealing piece 31 is rotatably mounted in the dust removal pipe 20. The sealing piece 31 comprises an open position and a sealing position. When the sealing piece 31 is located at the open position, the dust removal pipe 20 is in communication with the external negative pressure device, and at this time, the dust can be sucked away. When the sealing piece 31 is located at the sealing position, the dust removal pipe 20 is disconnected from the external negative pressure device.

[0059] The driving member 32 is in transmission connection with the sealing member 31, and is used to drive the sealing member 31 to rotate relative to the dust removal pipe 20 to switch between the open position and the sealing position. By arranging the sealing member 31 in the dust removal pipe 20 and arranging the driving member 32 to drive the sealing member 31 to rotate relative to the dust removal pipe 20 to switch between the open position and the sealing position, the opening or closing of the dust removal pipe is realized. When the workpiece of the corresponding processing station needs to be processed, only the corresponding dust removal pipe 20 needs to be opened, which can improve the dust removal effect, reduce the dust removal consumption, and thus reduce the dust removal cost.

[0060] Specifically, the sealing member 31 can be made of rubber. When the sealing member 31 is in the sealing position, the outer contour of the sealing member 31 is matched with the inner contour of the dust removal pipe 20, so that the sealing member 31 completely seals the dust removal pipe 20.

[0061] Please refer to Figures 3-4 The dust removal switching assembly 30 can further include a rotating member 33, a connecting rod 34, a sensor 35, and a sensing member 36. The rotating member 33 is rotatably installed in the dust removal pipe 20, and one end of the rotating member 33 extends out of the dust removal pipe 20 and is connected with one end of the connecting rod 34. The sensor 35 is arranged on the rack 200, and the sensing member 36 is arranged on the other end of the connecting rod 34, and is used to cooperate with the sensor 35 to detect the movement position of the connecting rod 34. The driving member 32 is in transmission connection with the connecting rod 34, and the sealing member 31 is installed on the rotating member 33. Specifically, the driving member 32 can be a pneumatic cylinder. The pneumatic cylinder drives the connecting rod 34 to swing, and then drives the rotating member 33 to rotate, so as to realize the rotation of the sealing member 31. The structure is simple, the volume is small, and it is beneficial to reduce the volume. The mutual cooperation of the sensor 35 and the sensing member 36 can detect the movement position of the connecting rod 34.

The dust removal cover 10 is installed on the adjusting seat 40. When it is necessary to adjust the position of the dust removal cover 10, the adjusting assembly 50 is first separated from the rack 200, and then the adjusting seat 40 can be moved along the first direction. When the adjusting seat 40 is moved to the preset position, the adjusting assembly 50 is connected with the rack 200 to fix the adjusting seat 40. Through the cooperation of the adjusting seat 40 and the adjusting assembly 50, the position of the dust removal cover 10 can be adjusted, and thus the dust removal for processing workpieces of different sizes can be realized.

[0064] When it is necessary to adjust the position of the adjusting seat 40, first, the first adjusting member 52 is pulled to move away from the plug-in hole 210, so that the first adjusting member 52 moves away from the plug-in hole 210 against the elastic pushing force of the elastic member, at this time, the first adjusting member 52 is separated from the plug-in hole 210, at this time, the position of the adjusting seat 40 along the first direction can be adjusted. When the adjustment is completed, it is only necessary to release the first adjusting member 52, at this time, under the action of the elastic pushing force of the elastic member, the first adjusting member 52 moves towards the plug-in hole 210 and extends into the corresponding plug-in hole 210 to be fixed, so that the fixing of the adjusting seat 40 is realized.
