[0062] The top of the horizontal rod of the structural frame 1 is fixedly connected with a bottom plate placing seat 11.

[0063] Wherein, the bottom plate placing seat 11 can place multiple workpiece bottom plates, so that the continuous feeding of the workpiece bottom plate is not required.

[0064] Working principle:

[0065] The user sets the device control unit program, sets a group of material guiding mechanisms 3 below the discharging groove 615, then places the workpiece barrel above the driving chain 307 and the driven chain 308, and places the bottom plate above the bottom plate placing seat 11;

[0066] The material guiding motor 305 is powered on to drive the driving shaft 309 to rotate, the two groups of driving gears 311 on the driving shaft 309 are engaged with the driving chain 307 and the driven chain 308, so that the driving chain 307 and the driven chain 308 can be moved, and the driven shaft 310 on the other side ensures the stability when the two groups of chains move, the workpiece barrel is guided by the two groups of limiting rods 313 and continuously transported into the limiting half ring 601 above the processing plate 4 for limiting, so that the feeding of the workpiece barrel is realized;

[0067] The electromagnetic power supply in the electromagnetic fixing disc 703 will generate a magnetic force to fix the workpiece barrel body. The X-axis displacement motor 805 is powered on to drive the X-axis drive screw 806 to rotate on the drive bearing seat 807. The two groups of X-axis screw nuts 808 on the Z-axis displacement seat 803 are connected with the X-axis drive screw 806, and drive the positioning mechanism 9 to move along the X-axis guide rail 802 through the X-axis guide slider 809. The Z-axis displacement motor 813 is powered on to drive the Z-axis drive screw 814 to rotate. The Z-axis screw nut 815 is connected with the Z-axis drive screw 814 to drive the positioning mechanism 9 to move along the Z-axis. The Y-axis displacement motor 818 is powered on to drive the Y-axis drive screw 819 to rotate. The Y-axis screw nut 820 is connected with the Y-axis drive screw 819 to drive the positioning mechanism 9 to move along the Y-axis. Thus, the Y-axis displacement slide plate 817 can be moved above the bottom plate placing seat 11. Then, a group of electric telescopic rods 901 is powered on. The electric telescopic rod 901 drives the rubber suction cup 910 to tightly contact the workpiece bottom plate on the top of the bottom plate placing seat 11 to squeeze out the air in the suction cup, and further extracts the air in the suction cup by powering on the dual-purpose air pump 907. Thus, the workpiece bottom plate is fixed by the air pressure difference between the inside and outside. When the electromagnetic wire 920 in the electromagnetic seat 917 is powered on, a magnetic field is formed and the electromagnet 919 is given a magnetic force. Thus, the workpiece bottom plate is further fixed by the magnetic force. After the fixing is completed, the workpiece bottom plate is moved above the limiting half ring 601, i.e., the workpiece barrel body, by the displacement mechanism 8 again. When the positioning mechanism 9 moves the workpiece bottom plate to the specified position above the electromagnetic fixing disc 703, the position sensor 704 receives the signal and transmits the signal to the control unit. The control unit analyzes the signal and transmits the instruction to the electromagnetic seat 917 and the dual-purpose air pump 907 through the control end 921. The electromagnetic wire 920 in the electromagnetic seat 917 is powered off, and the dual-purpose air pump 907 inflates the rubber suction cup 910 through the air guide pipe 911. The electromagnet 919 is powered off to release the fixation of the workpiece bottom plate. When the air pressure inside and outside the rubber suction cup 910 is consistent, the workpiece bottom plate will be released, and the bottom plate is placed above the workpiece barrel body after being turned over. Thus, the bottom plate of the barrel body is loaded;

[0068] The welding equipment head 10 is moved to the connection between the barrel body and the bottom plate by the displacement mechanism 8 again after the positioning mechanism 9 is recovered, and welding is performed. The rotary motor 702 is powered on to drive the electromagnetic fixing disc 703 and the workpiece to rotate as a whole to realize continuous welding;

[0069] After the welding is completed, the blanking motor 603 is powered on to drive the blanking driving gear 605 to rotate through the blanking coupling 606. The blanking driving gear 605 and the blanking driven gear 609 drive the transmission rack 610 and the transmission belt 611 to engage, so that the blanking driving gear 605 can drive the movable inner block 607 on the blanking driven gear 609 to rotate through the transmission belt 611 when rotating, and further drive the limiting half ring 601 and the workpiece to move. The workpiece is limited by the arc-shaped limiting plate 613 and the multiple sets of limiting columns 614, and can be moved as a whole to the blanking groove 615, and then falls from the blanking groove 615 to another set of material guiding mechanism 3 to guide the workpiece as a whole, so as to realize the welding function of the production line.

[0070] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
