[0037] Please refer to Figure 1 , a production system for welding the body of an iron can, including a three-dimensional warehouse, a can lid and bottom material taking machine 200, a can body material taking machine 300, a conveyor belt unit, a loading robot, a rolling machine 600, a clamping robot 700, a welding robot 800, a feeding cart 900, and a canning workbench 1000. Among them, the three-dimensional warehouse includes a first material warehouse 110 and a second material warehouse 120. The processed can bottoms and can lids are placed on the first material warehouse 110, and the unprocessed can bodies, that is, rectangular sheets, are placed on the second material warehouse 120. After being curled, the rectangular sheets become cylindrical can bodies.

[0038] There is a spacing between the first material warehouse 110 and the second material warehouse 120, and a can lid and bottom material taking machine 200 and a can body material taking machine 300 are provided between them. Among them, the can lid and bottom material taking machine 200 is arranged beside the first material warehouse 110, and the can body material taking machine 300 is arranged beside the second material warehouse 120.

[0039] The conveyor belt unit includes multiple conveyor belts. Among them, there are a can body conveyor belt 410, a can bottom conveyor belt 420, a can lid conveyor belt 430, a can filling conveyor belt 440, and a finished product conveyor belt 450. The can body conveyor belt 410, the can bottom conveyor belt 420, and the can lid conveyor belt 430 are arranged in parallel. One end of the can body conveyor belt 410 faces the can body material taking machine 300; one end of the can bottom conveyor belt 420 faces the can lid and can bottom material taking machine 200. The can filling conveyor belt 440 and the can bottom conveyor belt 420 are on the same straight line and are far from the end of the can bottom conveyor belt 420 close to the stereoscopic warehouse, and there is a distance between their ends.

[0040] The finished product conveyor belt 440 is perpendicular to the can bottom conveyor belt 420 and is located at the end far from the stereoscopic warehouse.

[0041] There are two loading robots. Among them, the first loading robot 510 is located between the can body conveyor belt 410 and the can bottom conveyor belt 420 and is close to the ends of both respectively, and is used to grab the can body on the can body conveyor belt 410 or the can bottom on the can bottom conveyor belt 420. The second loading robot 520 is located between the can lid conveyor belt 430 and the can filling conveyor belt 440 and is close to the ends of both respectively. The second loading robot 520 is used to grab the can lids on the can lid conveyor belt 430.

[0042] The rolling machine 600, the clamping robot 700, and the welding robot 800 are respectively arranged beside the first loading robot 510 and are arranged at intervals.

[0043] See Figure 2 , the first material warehouse 110 has multiple layers, and each layer is provided with multiple can lid and can bottom storage units. Each can lid and can bottom storage unit is used to store the processed circular can lids and can bottoms. See Figure 2 B and Figure 2 C. Each can lid and can bottom storage unit includes a large groove 111, and a small groove 112 is further provided at the bottom of the large groove 111. That is, the opening of the small groove 112 is provided at the bottom of the large groove 111, and the opening width of the small groove 112 is about half of the bottom width of the large groove 111. The diameters of the can lids and can bottoms are slightly smaller than the bottom width of the large groove. In this way, the can lids and can bottoms are placed on the bottom of the large groove 111. When taking materials, the material taking mechanism can insert into the bottoms of the can bottoms and can lids from the small groove.

[0044] The structure of the second material warehouse 120 is similar to that of the first material warehouse 110. The difference is that since the unprocessed can body is rectangular, the width of the large groove needs to be widened.

[0045] See Figures 3 to 7The tank cover and bottom reclaiming machine 200 includes an AGV walking trolley 210. The AGV walking trolley 210 is provided with a bracket 220 vertically upward, and a lifting platform 230 is provided on the bracket 220 and can move up and down along the bracket 220 and be positioned. A sliding seat 250 is provided on the lifting platform 230, and the sliding seat 250 is fixed to a gas rod 240. The movement of the gas rod can make the sliding seat 250 slide horizontally relative to the upper surface of the lifting platform 230. A tank cover and bottom magnetic suction cup 260 is provided at one end of the sliding seat 250. Figure 6 The tank cover and tank bottom magnetic suction cup 260 includes an electromagnetic unit 261 and an electromagnetic disk box 262 .

[0046] See also Figure 7 The structure of the can body picker 300 is basically similar to that of the can cover and bottom picker 200, except that the can cover and bottom magnetic suction cup 260 is replaced by a can body magnetic suction cup 360, and the can body magnetic suction cup 360 includes an electromagnetic unit 361 and an electromagnetic disk box 362, and the size of the electromagnetic unit 361 is larger than the electromagnetic unit 261.

[0047] See also Figures 8 to 12 The clamping robot 700 includes a base 710 and a mechanical arm 720, and a clamping tool 730 is fixed at the end of the mechanical arm 720. The clamping tool 730 includes two clamping rollers, each of which is composed of two inferior arcs 731 and two arc-shaped sliders 732 to form a ring, wherein the two arc-shaped sliders 732 are respectively arranged at the two ends of the same diameter of the circle. The two clamping rollers are connected by a connecting pipe 734, and the two ends of the connecting pipe 734 pass through the center of the two clamping rollers, and two branch pipes 735 are extended at the center of the circle in the direction of the two arc-shaped sliders 732, and two connecting rods 733 are extended to the middle points of the two inferior arcs. It also includes two dumbbell-shaped sliders 736, wherein one end of each dumbbell-shaped slider 736 is fixedly connected to the arc-shaped slider 732, and the other end is inserted into the branch pipe 735 and fixedly connected to the rack 739. A micro electric roller 737 is provided in the connecting tube 734 , and a gear 738 is connected to the outer circumferential surface of the end of the cylinder of the micro electric roller 737 through a key connection, etc., and racks 739 on both sides are respectively meshed with the gear 738 on the gear electric roller 737 .

[0048] The front shaft 737-1 and the rear shaft 737-2 at both ends of the gear electric roller 737 are fixed to the inner surface of the connecting tube 734 through connecting parts such as bearings and bearing seats. The electric roller body rotates clockwise to make the rack meshing with the gear 738 on the outer surface of its end translate inward at the same time, thereby driving the double dumbbell-shaped connecting piece and the arc-shaped electromagnetic slider 734 connected to the other end of the rack to retract slightly inward, thereby realizing the separation of the welded iron can body and the fixture; the electric roller body rotates counterclockwise to make the rack meshing with the gear 738 on the outer surface of its end translate outward at the same time, thereby driving the double dumbbell-shaped connecting piece and the arc-shaped electromagnetic slider 734 connected to the other end of the rack to translate slightly outward, reaching the same circumference as the adjacent inferior arc slider 731, thereby realizing the iron can body rolled out on the rolling machine by magnetic adsorption. Acceptance, positioning, and rolling are prepared for the next step of iron can body welding.

[0049] The micro electric roller has the advantages of compact structure, high transmission efficiency, low noise, long service life, stable operation, reliable operation, good sealing, small space occupation, easy installation, etc., and can be purchased commercially.

[0050] The number of miniature electric rollers 737 is preferably two, one being provided at each clamping roller.

[0051] See also Figure 13 and Figure 14 The charging cart 900 includes an AGV traveling trolley 910 located at the bottom and a load-bearing rod 920 arranged on the AGV traveling trolley. A barrel fixing frame 930 is provided at the upper end of the load-bearing rod 920, and a barrel 940 is provided in the barrel fixing frame 930.

[0052] The use of the utility model is as follows:

[0053] The rectangular can body plates stored in the second material warehouse 120 are placed in the can body conveyor belt 410 through the can body picker 300, and then sent to the plate rolling machine 600 through the first loading robot 510. The arc sliders 732 in the two clamping rollers of the clamping robot 700 are both electromagnets. After the plate rolling machine 600 rolls the can body plate, the arc slider 732 will immediately suck one end of the plate, and make the connecting tube rotate to drive the clamping roller to follow the frequency of the curling machine to roll the plate on the clamping roller. After the clamping roller rotates one circle to wrap the curled plate one circle, the energized moving slider will re-adsorb the other end of the plate and make the two ends of the plate overlap, forming the overlap area required for roller welding and preparing for the welding process. The robot arm can drive the connecting tube to rotate in various existing ways. For example, the end of the connecting tube is square, and the robot arm has a corresponding square output shaft end.

[0054] The adsorbed and lapped coiled sheet is then welded by the welding robot 800. The tank bottom stored in the first material warehouse 110 is sent to the tank bottom conveyor belt 420 by the tank lid and bottom feeder 200, and then grabbed by the first loading robot 510 and assembled with the welded tank body (at this time, the tank body is still fixed on the clamping robot 700). After the tank bottom and the tank body are assembled, the arc-shaped slider 732 on the clamping roller drives the gear to rotate under the rotation of the micro electric roller, and then drives the rack 739 to move. The arc-shaped slider 732 contracts towards the center of the clamping roller and separates from the lapped welding joint, so that the fixture can easily detach from the tank body and return to the production of the next tank body.

[0055] After the tank body and the tank bottom are assembled, they enter under the canning workbench 1000 for canning the product. After canning, the second loading robot 520 grabs the tank lid on the tank lid conveyor belt 430 to seal the top of the can. The tank lids on the tank lid conveyor belt 430 are also sent from the first material warehouse 110 to the tank lid conveyor belt 430 by the tank lid and bottom feeder 200.

[0056] As mentioned above, it is only a preferred embodiment of the present utility model, so the scope of implementation of the present utility model cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present utility model patent and the content of the specification should still fall within the scope covered by the present utility model.
