The working principle of the invention is as follows:

the double-station fragment blanking machine 2 firstly conveys the end plate single sheet with the opening to the end plate bearing platform 1, wherein the specific blanking operation of the double-station fragment blanking machine 2 is as follows: a piston rod of the first air cylinder 214 extends out to enable the first turnover frame 213 and each fragment blanking platform to keep an inclined shape which gradually inclines upwards from back to front, then the horizontal pushing air cylinder 219 acts to drive the first moving frame 212 to move left and right along the first track 211, one fragment blanking platform on the first moving frame 212 is enabled to be butted with the end plate bearing platform 1 through the corresponding guide plate 218, then the blanking air cylinder 217 corresponding to the fragment blanking platform acts, the corresponding material pushing backup plate 216 is pushed to move forwards along the corresponding first guide rod 215 until the end plate with the opening is pushed out of the corresponding fragment blanking platform, and the end plate which pushes out the fragment blanking platform can slide onto the end plate bearing platform 1 along the corresponding guide plate 218;

after the end plate accepting platform 1 accepts an end plate, the action of the feeding mechanism 4 causes the end plate to accept the end plate propelling movement on the platform 1 to the reversing roller conveyor 3, and the specific feeding operation of the feeding mechanism 4 is as follows: the feeding air cylinder 412 acts to move the first feeding wedge block 416 backwards to the rear of the end plate, and then the feeding air cylinder 412 acts again to drive the first feeding wedge block 416 to move forwards and push the end plate to move forwards on the reversing roller conveyor 3 synchronously;

then the reversing roller conveyor 3 conveys the connected end plates at the left end and the right end respectively, then the seam searching and pushing mechanisms 6 at the two sides push the end plates conveyed to the two ends of the reversing roller conveyor 3 forwards to the seam searching mechanism 5 in front respectively, and then the seam searching mechanism 5 acts to place the connected end plates in a state that the openings of the connected end plates face forwards; the specific seam searching operation of the seam searching mechanism 5 is as follows: in an initial state, the lifting plate 514 is flush with the seam searching rotary table 512, after the end plate reaches the seam searching rotary table 512, the seam searching lifting cylinder 515 lowers the lifting plate 514 below the seam searching rotary table 512, so that the edge of the end plate on the seam searching rotary table 512 is just exposed out of the seam searching rotary table 512, then the seam searching motor 5 drives the seam searching rotary table 512 to rotate, the end plate on the seam searching rotary table 512 is synchronously driven to rotate, in the process that the end plate rotates along with the seam searching rotary table 512, the laser sensor 517 can detect the opening position of the end plate in real time, when the laser sensor 517 detects the opening of the end plate, the seam searching motor 5 stops acting, and at the moment, the end plate is placed in a state that the opening faces forwards;

then the stepping translation turnover mechanism 11 can take out the end plate on the seam searching mechanism 5 and place the end plate on the first bracket 7, then the edge pressing machine 8 acts to tightly press and fix the end plate on the first bracket 7, and then the welding robot 10 at the first bracket 7 acts to weld the opening on the front surface of the end plate; after the welding is finished, the edge pressing machine releases the end plate, then the stepping translation turnover mechanism 11 takes out the end plate on the first bracket 7, turns over the end plate by 180 degrees and then places the end plate on the second bracket 9; then the welding robot 10 at the second bracket 9 acts to weld the opening of the reverse side of the end plate, at the moment, the opening of the end plate is welded and closed, but the front side and the reverse side of the end plate are not flat, and then the front side and the reverse side of the end plate are leveled;

then the end plate on the second bracket 9 is hooked to the first roller conveyor 12 by the hooking device 13, the first roller conveyor 12 conveys the end plate from two sides to the middle to the second roller conveyor 14, the second roller conveyor 14 conveys the received end plate to the first flattening machine 15, when the end plate reaches the output end of the second roller conveyor 14, the first lifting device 16 lifts the end plate conveyed to the output end of the second roller conveyor 14 up to be opposite to the inlet of the first flattening machine 15, and then the first pushing device 17 pushes the end plate lifted by the first lifting device 16 to the first flattening machine 15;

then, the first flattening machine 15 flattens the entered end plate for one time, the flattened end plate is conveyed forwards to the third roller conveyor 18, the third roller conveyor 18 conveys the end plate forwards to the turnover device 20, the turnover device turns the end plate 180 degrees and then places the end plate on the fourth roller conveyor 19, then the fourth roller conveyor 19 continues to convey the end plate forwards, and when the end plate reaches the output end of the fourth roller conveyor 19, the second pushing device 22 pushes the end plate conveyed to the output end of the fourth roller conveyor 19 into the second flattening machine 21;

then, the second flattening machine 21 performs secondary flattening on the entered end plate, and then the flattened end plate is conveyed forwards to a fifth roller conveyor 23, at this time, the end plate which completes the secondary flattening is a finished end plate, and the fifth roller conveyor 23 receives the finished end plate and then conveys the end plate forwards to a double-station unloader 24 for storage;

the specific discharging operation of the double-station discharger 24 is as follows: the second air cylinder 249 operates to drive the fourth moving frame 242 to move horizontally along the fifth rail 241, so that one of the discharging guide frames 246 on the fourth moving frame 242 is butted with the output end of the fifth roller conveyor 23, after the end plate output by the fifth roller conveyor 23 slides down to the butted discharging guide frame 246, the upper discharging air cylinder 247 and the lower discharging air cylinder 248 corresponding to the discharging guide frame 246 operate, the upper discharging air cylinder 247 and the lower discharging air cylinder 248 push the received end plate forward to the stack 244 corresponding to the front, then the translation air cylinder 245 corresponding to the discharging guide frame 246 operates to drive the stack 244 corresponding to the discharging guide frame 246 to move forward by one body position, the above operations are repeated until the stack is full of end plates, then the second air cylinder 249 is started again to drive the fourth moving frame 242 to move horizontally along the fifth rail 241, so that the other discharging guide frame 246 on the fourth moving frame 242 is butted with the output end of the fifth roller conveyor 23, the end plates are stored by another empty rack, and the end plates on the rack full of end plates are taken away by workers at the same time.
