[0031] The grinding assembly 31 includes a moving frame 311, on which the output end of the linear driving member c306 is installed. A driving rod 312 and two rotating rods 313 are rotatably provided on the moving frame 311. A grinding belt 314 is sleeved on the outer sides of the driving rod 312 and the two rotating rods 313. A rotating driving member d315 is installed on the moving frame 311. The output end of the rotating driving member d315 and the driving rod 312 are connected by a fourth belt 316. A plurality of third card slots 3141 are provided in the grinding belt 314. A card block 300 is installed on the driving rod 312 and the rotating rod 313. The card block 300 is inserted into the third card slot 3141. The rotation of the driving rod 312 drives the card block 300 to rotate, thereby driving the grinding belt 314 to move.

When the concave welding area ( Fig.14 When grinding in the c state), the linear drive member d317 drives the driving wheel 319 to move forward, squeezing the grinding belt 314 into the concave welding area. The movement of the grinding belt 314 can grind the concave welding area, thereby realizing the grinding of straight, convex and concave welding areas.

[0035] like Figure 1-Figure 16As shown, the laser welding mechanism 5 includes: a fixed plate 501, which is installed on the workbench 100; a second guide rail 502, which is installed on the fixed plate 501; a sliding block 503, which is slidably arranged on the second guide rail 502; a rotating driving member e504, which is installed on the sliding block 503; a U-shaped frame 505, which is installed on the output end of the rotating driving member e504; and a laser welding assembly 51, which is installed on the U-shaped frame 505.

[0038] The coating mechanism 4 includes: a linear driving member f401, which is mounted on the U-shaped frame 505; and a coating nozzle 402, which is mounted on the output end of the linear driving member f401.

[0039] In this embodiment, the rotary drive member e504 drives the U-shaped frame 505 to rotate, driving the coating nozzle 402 toward the lower shell 802 and the upper shell 801, and the linear drive member f401 drives the coating nozzle 402 to contact the welding gap between the lower shell 802 and the upper shell 801. The coating nozzle 402 applies the anti-transmittance agent to the welding gap between the lower shell 802 and the upper shell 801, and cooperates with the rotation of the lower shell 802 and the upper shell 801 to further apply the anti-transmittance agent to the welding gap around the lower shell 802 and the upper shell 801. The polished welding gap area is conducive to absorbing the anti-transmittance agent. It should be noted that the coating nozzle 402 is connected to the liquid supply device through a hose. The liquid supply device is a prior art and will not be described in detail here. The liquid supply device injects the permeability enhancer into the coating nozzle 402 through the hose to realize the supply of the permeability enhancer.

Similarly, laser welding is performed on the second straight edges, the third straight edges, and the fourth straight edges.

[0042] It should be noted that the welding gap alignment (adsorption correction) of the lower shell 802 and the upper shell 801 is aimed at the straight welding area. When the sliding block 503 slides on the second guide rail 502, the moving belt 523 slides along the groove 5211, and the moving belt 523 area corresponding to the square groove 5212 always performs adsorption correction on the welding edges of the lower shell 802 and the upper shell 801.

At this time, the lower shell 802 and the upper shell 801 are both located in the receiving groove 1011. Due to the peripheral limit of the receiving groove 1011, the positions of the lower shell 802 and the upper shell 801 are aligned; Step 2, clamping process: the linear drive component b203 drives the moving rod b204 to move downward, driving the second clamping plate 205 to move and press on the upper shell 801.

The coating nozzle 402 coats the anti-permeability agent on the welding gap between the lower shell 802 and the upper shell 801, and cooperates with the rotation of the lower shell 802 and the upper shell 801 to further coat the anti-permeability agent on the welding gap around the lower shell 802 and the upper shell 801. The polished welding gap area is conducive to absorbing the anti-permeability agent; Step 5, first welding process: drive the lower shell 802 and the upper shell 801 to rotate so that the first straight edge corresponds to the position of the laser welding mechanism 5, the linear drive member e511 drives the moving belt 523 of the adsorption assembly 52 to contact the first straight edge of the lower shell 802 and the upper shell 801, and the pipeline 524 introduces negative pressure into the square groove 5212, and the negative pressure passes through the through hole 5231 to adsorb the first straight edge of the lower shell 802 and the upper shell 801, and adsorb and correct the welding edge of the lower shell 802 and the upper shell 801, so that the welding gap of the lower shell 802 and the upper shell 801 is aligned, and the welding edge of the lower shell 802 and the upper shell 801 is prevented from bending and deforming inward (slightly), resulting in uneven welds during welding; The laser welding head 517 performs laser welding on the gap between the lower shell 802 and the upper shell 801. The sliding block 503 slides on the second guide rail 502, and the moving belt 523 slides along the groove 5211. The first straight edge of the lower shell 802 and the upper shell 801 is laser welded. Similarly, the second straight edge, the third straight edge, and the fourth straight edge are laser welded.
