s3, after the sub-box 12 is welded, the clip frame 14 is placed in a medium-sized limiting cavity, the third cylinder 310 drives the sliding plate 313 to move along the fourth linear guide rail 312, the sliding plate 313 moves to enable the third limiting block 311 to abut against and limit the side edge of the clip frame 14, the clip frame 14 abuts against and then places the welded mother box 13 in the medium-sized limiting cavity, the rotary cylinder 302 drives the first gear 303 to rotate, the first gear 303 and the second gear 304 are in tooth joint and match to enable the rotating shaft 307 to rotate, the rotating shaft 307 rotates to drive the turning press plate 305 to overlap around the clip frame 14, after the turning press plate 305 abuts against the clip frame 14, the spring pin 309 is inserted into the slot on the rotating shaft 307 to achieve the positioning of the turning press plate 305, then the PC computer cabinet 11 controls the second clamp 3 to move along the first linear guide rail 101 and move to the lower part of the welding box 6, and after the welding box 6 detects the second laser clamp 3, the laser welding box 6 is controlled by the PC computer cabinet 11 to realize back-and-forth laser welding along the third linear guide rail 5, and the baking box is taken out after the welding of the gap between the rectangular frame 14 and the female box 13 is finished.

By utilizing the baking box forming method, the plurality of sub-boxes 12 are fixed by the first clamp 2 and then are sent to the lower part of the laser welding box for welding operation, the feeding and welding of the sub-boxes 12 are synchronously carried out, the welding efficiency of the sub-boxes 12 is improved, and the flanged edges of the sub-boxes 12 in the same row and the same column and the sub-boxes 12 in the adjacent rows and columns are in the same plane, so that the straight splicing seams 15 are obtained. During welding, the welding is only needed to be carried out on the straight splicing seam 15, and the welding efficiency of the sub-box 12 is improved.

The plurality of sub-boxes 12 are welded together to form a welded mother box 13, then the welded mother box 13 is placed in the square frame 14, the whole square frame 14 and the mother box are placed on the second fixture 3 and conveyed to the lower part of the laser welding box by the second fixture 3, the laser welding box is used for carrying out laser welding on the side seams of the square frame 14 and the mother box 13, (the square frame is a square frame, the edge of the mother box is lapped at the upper edge of the square frame, the lap joint of the edge of the mother box and the upper edge of the square frame is welded), the laser welding box is used for carrying out laser welding on the side seams of the square frame 14 and the mother box 13, the feeding and welding of the square frame 14 and the mother box 13 are carried out synchronously, the efficiency of the side seam welding between the square frame 14 and the mother box 13 is effectively improved, the process of forming the baking box is reduced, the automatic welding can be realized, and the welding seams are uniform, no grinding is required before spraying. The front and rear double stations are adopted, four stations are totally adopted, the front end is welded in a medium-sized mode, the rear end is welded with the rectangular frame 14, during working, feeding and welding time are overlapped, light-emitting time of a laser is shortened, efficiency is improved, laser welding speed is up to 100mm/s, one-plate product manufacturing can be completed within 90 seconds basically, and manufacturing time is shortened in multiples. A plurality of sub boxes are welded into a main box 13, and then the main box is welded with the clip-shaped frame 14 for forming, so that materials can be greatly saved. Because of the automated production, the number of operators can be reduced. In addition, compared with the traditional process, the box holes are punched on the flat plate firstly, and then the punched boxes are punched and riveted into the flat plate with the box holes, the punching is needed for multiple times, the forming efficiency of the baking box is low, the obtained baking box has a large gap at the punched and riveted position after a long time, and some boxes can directly fall off. The baking box welded and formed by the method has high strength, and can not loosen and fall off even being beaten by long-time vibration, so that the service life is prolonged. In addition, the baking box obtained by welding has a flat surface, does not have concave-convex steps, is not easy to stick ash, is easy to clean, can be repeatedly used, and ensures the safety of cake food.
