[0026] like Figure 1-4As shown, the utility model provides a technical solution: a laser welding workstation, comprising a welding machine cabinet 1, an XYZ module 2 is installed inside the welding machine cabinet 1, a fixed plate 3 is fixed to the front of the XYZ module 2 and located inside the welding machine cabinet 1, a galvanometer welding head 4 is fixed to the front of the fixed plate 3 near the top, a collimator 5 is fixed to the left side of the galvanometer welding head 4 near the top, a pressure head 6 is fixed to the bottom of the collimator 5, a field lens 7 is fixed to the bottom of the galvanometer welding head 4, a wind knife 8 is installed below the field lens 7, an altimeter 9 is installed on the right side of the wind knife 8, and the altimeter 9 is fixed to the fixed plate 3, a visual camera 10 is fixed to the right side of the galvanometer welding head 4 near the top, a light source 11 is fixed to the right side of the galvanometer welding head 4 and located below the visual camera 10, which can effectively provide light for the visual camera 10. Example

[0027] like Figure 1-4 As shown, a pneumatic door 101 is fixedly connected to the front of the welding machine cabinet 1, and an industrial control computer 102 is fixedly connected to the front of the welding machine cabinet 1 near the right side, so that the equipment can be conveniently controlled through the industrial control computer 102.

[0028] A chiller 103 is installed on the left side of the welding machine cabinet 1, and a dust collector 104 is installed on the right side of the welding machine cabinet 1, so that dust removal work can be carried out conveniently through the dust collector 104.

[0029] A dust extraction pipe 105 is installed on the front of the collimator 5 , and the dust extraction pipe 105 is connected to the dust collector 104 , so that the dust collector 104 can extract dust from the inside of the welding machine cabinet 1 .

[0030] The XYZ module 2 includes a double Y-axis 21 symmetrically fixed inside the welding machine cabinet 1. The top of the double Y-axis 21 is laterally slidably connected to the X-axis 22, and the top of the X-axis 22 is slidably connected to the Z-axis 23. The fixing plate 3 is fixed to the Z-axis 23 to facilitate welding positioning.

[0031] The welding machine cabinet 1 is laterally passed through by the lithium battery assembly line, and the lithium battery assembly line is located below the altimeter 9 .

[0032] The working process of the present invention is as follows: when using a laser welding workstation for laser welding, first, when the lithium battery aluminum bar to be welded passes through the assembly line tray and enters the interior of the welding machine cabinet 1, after entering, the tray stops moving when it reaches the position. At this time, the pneumatic door 101 is closed to prevent the laser from injuring people. Then the lifting mechanism of the assembly line lifts the tray. After lifting, the light source 11 is turned on, and the visual camera 10 captures the welding points on the aluminum bar and measures the distance through the altimeter 9. The industrial control computer 102 controls the XYZ module 2 to move into position according to the captured coordinates.
