[0032] In actual application of the embodiment of the present invention, the frame body 204 is placed on the pre-stored conveyor belt 203 by controlling the operation of the pre-stored conveyor belt 203, and then the pre-stored conveyor belt 203 will transport the frame body 204 to the processing table 3. Since the height of the processing table 3 is higher than the pre-stored rack 2, the frame body 204 closest to the processing table 3 will be attached to the surface of the processing table 3.

At this time, the first connecting rod 502 is controlled to slide in the first inclined groove 501, thereby driving the positioning frame 503 to move inward at the same time. The positioning frame 503 will contact the raised frame body 204, thereby pushing the frame body 204 to move, so that the frame bodies 204 gradually move closer to each other, and under the positioning effect of the positioning frame 503, the two ends of the frame body 204 can be connected to each other, so that the four frame bodies 204 form a rectangle and are positioned, and then the pressing block 80 is controlled. 2 is moved downward to press down the connection of the frame body 204 so that the connection of the frame body 204 is flush. At this time, the welding mechanism 6 can be controlled to operate. Since there are four groups of welding guns 604, the four connections of the frame body 204 can be welded at the same time. The welding guns 604 in each group of welding guns 604 are symmetrically arranged up and down, so that the connection of the frame body 204 is located between the welding guns 604, and then the upper and lower sides of the connection of the frame body 204 can be welded at the same time, thereby achieving the effect of quickly welding the connection of the frame body 204.

When the lifted frame body 204 is positioned on the processing table 3, the lifting block 401 is controlled to reset, and then the frame body 204 pre-stored on the conveyor belt 203 will fill the vacant position, so that the next frame body 204 is in contact with the surface of the processing table 3, preparing for subsequent processing and welding. At the same time, as the processing proceeds, the frame body 204 pre-stored on the conveyor belt 203 will gradually decrease.

When in the spread and moved position, by controlling the welding gun 604 to turn on, the welding gun 604 will move along the connection of the frame body 204, thereby achieving the effect of welding the connection of the frame body 204. Since four groups of welding guns 604 are provided, not only can multiple connections be welded at the same time, but also each group of welding guns 604 is symmetrically arranged up and down, so that the upper and lower sides of the connection can be welded at the same time, thereby making the welding efficiency higher.
