[0046] Please refer to Figure 5 The welding machine proposed in this embodiment has the following main working process: (1) The spring piece is fed by the feeder at the feeding station a, and then the third conveying assembly 32 vacuum-absorbs the spring piece. Then, the third conveying assembly 32 drives the absorbed spring piece to move to the top of the lower camera 7 under the drive of the servo motor to take a picture and determine the position of the spring piece; (2) For flat welding, wait for the shell to enter the welding station d; for side welding, the third conveying assembly 32 places the spring piece on the transfer fixture 6, and the suction cup on the transfer fixture 6 vacuum sucks the spring piece. The fixture structure on the transfer fixture 6 also performs mechanical secondary positioning on the spring piece. At this time, wait for the shell to move to the welding station d; (3) When (1) and (2) occur, the shell flows to the shell loading station b through the loading conveyor line 8. For flat welding, the shell is transported to the first conveying assembly 12 by the shell loading mechanism 5, and the first conveying assembly 12 directly transports the shell to the welding station d. For side welding, the shell is transported to the second conveying assembly 22 by the shell loading mechanism 5, and the second conveying assembly 22 rotates a certain angle to make the shell stand sideways and transports the shell to the welding station d at the same time. The first conveying assembly 12 and the second conveying assembly 22 belong to Figure 5 "Mobile Vehicle" in (4) When the shell is transported to the welding station d, for flat welding, the third conveying assembly 32 will place the spring piece at a designated fixed position on the shell before welding; for side welding, the transfer fixture 6 will fit the spring piece to the fixed position of the shell, and when the spring piece is in place, the pressing tool of the transfer fixture 6 will press the spring piece, and then welding will be carried out. After welding is completed, the transfer fixture 6 will remove the pressing tool; (5) After the welding is completed, the shell is transported to the shell unloading station c by the first conveying assembly 12 or the second conveying assembly 22, and then the shell loading mechanism 5 moves the shell with the shrapnel welding to the unloading conveying line 9 to complete the unloading.

[0047] In the welding machine proposed in the embodiment of the present invention, the shrapnel conveying mechanism 3 cooperates with the first conveying mechanism 1 of the shell to realize fully automatic flat welding of the shell, and the shrapnel conveying mechanism 3 cooperates with the second conveying mechanism 2 of the shell to realize fully automatic side welding of the shell, thereby solving the problem that the shrapnel welding machine can realize fully automatic welding of shrapnel and is compatible with flat welding and side welding. During the welding process, the laser welder 43 and the moving third conveying assembly 32 and the moving first conveying assembly 12 and the second conveying assembly 22 are at different heights, so this solution will not have the risk of mutual collision during operation, and there is no need to wait, thereby improving production efficiency.

[0048] In other embodiments of the present invention, please refer to Figure 6 The above-mentioned transfer fixture 6 is also set at one end of the first guide rail 111 close to the shrapnel conveying mechanism 3, and the first conveying component 12 and the second conveying component 22 can be used for side welding, and the shells on the first conveying component 12 and the second conveying component 22 can be rotated to present different side postures; or the transfer fixture 6 can be disabled and ignored, and the first conveying component 12 and the second conveying component 22 can be used for flat welding.
