[0036] Start the second adjusting motor 133 to drive the second adjusting double-headed threaded screw rod 132 to rotate, so that the two adjusting slides 128 move toward each other or away from each other, and then the two positioning short strips 112 move toward each other or away from each other. Start the second limiting motor 131 to drive the second limiting double-headed threaded screw rod 130 to rotate, so that the two limiting strips 129 move toward each other or away from each other.

[0037] The protection component also includes a cross slide 123, an unlocking electric cylinder 122 is fixedly installed on the base plate 101, the cross slide 123 is fixedly installed on the piston rod end of the unlocking electric cylinder 122, two limiting long ratchet bars 125 and two limiting long ratchet bars 2 134 are fixedly provided on the cross slide 123, and a positioning ratchet bar 124 is fixedly installed on the limiting strip plate 114.

Under the action of the limiting strip 114 and the limiting strip 2 129, the positioning long strip 111 and the positioning short strip 112 are prevented from causing deformation of the plate. Under the action of the positioning ratchet 124, the limiting long ratchet 125, the limiting long ratchet 2 134, and the positioning ratchet 2 135, the positions of the limiting strip 114 and the limiting strip 2 129 are locked.

[0054] The bottom plate 101 is provided with a bending assembly, which includes a bending upper mold 109 and a bending lower mold 127. The bending upper mold 109 and the bending lower mold 127 are used to bend the plate. An L-shaped lower pressing plate 102 is slidably installed on the bottom plate 101, a lower pressing motor 106 is fixedly installed on the bottom plate 101, and a lower pressing screw rod 107 is rotatably installed on the bottom plate 101. The output shaft of the lower pressing motor 106 is fixedly connected to the lower pressing screw rod 107, and the lower pressing screw rod 107 and the L-shaped lower pressing plate 102 form a spiral pair. A mounting base 108 is fixedly provided on the lower end surface of the L-shaped lower pressing plate 102. The mounting base 108 and the bending upper mold 127 are fixedly provided. Bolt one is symmetrically arranged between the molds 109, and the mounting base plate 108 and the bending upper mold 109 are fixedly connected by bolt one. A mounting base plate 2 126 is also slidably installed on the base plate 101, and a supporting electric cylinder 121 is symmetrically fixedly installed on the base plate 101. The piston rod end of the supporting electric cylinder 121 is fixedly connected to the mounting base plate 2 126, and bolt two is symmetrically arranged between the mounting base plate 2 126 and the bending lower mold 127. The mounting base plate 2 126 and the bending lower mold 127 are fixedly connected by bolt two. The bending upper mold 109 and the bending lower mold 127 can be easily replaced by bolt one and bolt two.

[0055] After the auxiliary component completes the welding of the superimposed plates, the auxiliary plate returns to its initial position, and the positioning long strip plate 111 and the positioning short strip plate 112 are re-fixed on the plates, and then the yield motor 118 is started to make the two supporting slides 110 move in the direction away from each other, and finally make the distance between the two supporting slides 110 equal to the width of the bending lower mold 127, and then start the supporting electric cylinder 121 to make the mounting base 2 126 move upward, and the bending lower mold 127 moves upward synchronously, and finally make the upper surface of the bending lower mold 127 and the upper surface of the supporting slide 110 in the same plane, and then start the pressing motor 106 to drive the pressing screw 107 to rotate, that is, make the L-shaped lower pressing plate 102 move downward, and the mounting base 108 and the bending upper mold 109 move downward synchronously, under the action of the bending upper mold 109 and the bending lower mold 127, the plate between the positioning long strip plate 111 and the positioning short strip plate 112 is pressed and bent, that is, the plate is bent.

[0056] Working principle: Place the plate on the supporting plane, and then adjust the position of the plate through the positioning component so that the plate is located in the center of the supporting plane. Under the action of the protection component, the plate is prevented from being deformed under the action of the positioning long strip 111 and the positioning short strip 112. The plate is then leveled by the leveling component. After the leveling of the plate is completed, the positioning component is used to adjust the position of the plate again.

[0057] Then the positioning long strips 111 and the positioning short strips 112 are returned to their initial positions, and the plates to be stacked are placed on the plates. The above steps are repeated to process the plates to be stacked in sequence. After the plates to be stacked are processed, the plates are positioned by the positioning assembly, and then the auxiliary assembly is used to first press the long strips 157 to fix the two sides of the plates, and then the positioning long strips 111 and the positioning short strips 112 are returned to their initial positions, and then the welding gun 156 is used to weld the joint positions of the stacked plates. After the welding of the plates is completed, the positioning long strips 111 and the positioning short strips 112 are fixed to the plates again, and then the two supporting slides 110 are moved away from each other, that is, the lower bending mold 127 is moved to the bottom of the stacked plates, and then the bending process of the plates is realized under the action of the bending assembly.

[0058] The present invention is not limited to the above-mentioned specific embodiments. Various modifications made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
