[0002] Currently, a one-way sheet is welded to the foaming agent injection hole on the refrigerator bottom steel. This sheet covers the hole after the foaming agent is injected by the foaming agent injection gun, preventing the foaming agent from escaping the hole. Currently, the one-way sheet is manually placed over the foaming agent injection hole on the refrigerator bottom steel. One side of the sheet is then welded to the bottom steel on a welding machine to cover the hole. This process requires manual handling of the refrigerator bottom steel and the one-way sheet, which is not only time-consuming and labor-intensive, but also prone to inaccurate welding. Therefore, a device is needed that can automatically weld the refrigerator bottom steel and the one-way sheet. Utility Model Content

[0019] The present invention will be described in detail below with reference to the accompanying drawings:

[0020] Combine Figures 1 to 5 A device for welding one-way sheets to the bottom steel of a refrigerator comprises a main body 1, the top of the main body being a work surface 2, a first bracket 3 being provided at the rear of the work surface, a second bracket 4 being provided at the middle of the work surface, a bottom steel placement rack being provided at the front of the work surface, a laser welding mechanism 5 being provided on the first bracket, a one-way sheet taking mechanism and a one-way sheet stacking mechanism being provided on the second bracket, and the bottom steel 6 being placed on the bottom steel placement rack.

[0021] Among them, the bottom steel placement rack includes a front placement rack 7 and a rear placement rack 8. The top of the front placement rack 7 is provided with a front placement plate 9, and the top of the rear placement rack 8 is provided with a rear placement plate 10.

[0022] After the bottom steel 6 is stamped and formed on the production line, it can be taken by a robot and placed on the bottom steel placement rack. The front plate of the bottom steel is placed on the front placement plate 9, and the rear plate of the bottom steel is placed on the rear placement plate 10. The foaming agent injection hole 11 is in the center of the front plate of the bottom steel.

[0023] The laser welding mechanism includes a hand-cranked screw lifting frame 12 fixedly connected to the first bracket 3, and a movable plate 13 is slidably connected to the hand-cranked screw lifting frame 12. The hand-cranked screw lifting frame can drive the movable plate to move up and down. The hand-cranked screw lifting frame 12 drives the movable plate to move up and down, which is an existing technology.

[0024] A transverse support plate 14 is fixedly connected to the movable plate 13 , and a laser welding module 15 is fixedly connected to the front of the transverse support plate. The laser welding module 15 is a prior art.

[0025] The one-way sheet picking mechanism includes a support platform 16, on which a first slide cylinder 17 is horizontally fixedly connected, and a second slide cylinder 18 is vertically fixedly connected to the slider of the first slide cylinder 17. Specifically, a cylinder fixing plate 19 is fixedly connected to the slider of the first slide cylinder 17, and the second slide cylinder 18 is vertically fixedly connected to the cylinder fixing plate 19. The first slide cylinder can drive the second slide cylinder to move forward and backward.

[0026] An L-shaped fixing plate 20 is fixedly connected to the slider of the second slide cylinder 18 , a pressing plate 21 is fixedly connected to the bottom of the fixing plate 20 , a suction cup 22 is provided at the bottom of the pressing plate, and a long strip opening 23 is opened at the rear of the pressing plate.

[0027] The one-way sheet stacking mechanism is used to place the stacked one-way sheets 24. The one-way sheet stacking mechanism includes a lifting motor 25, a left vertical plate 26, a front vertical plate 27, and a rear vertical plate 28. The left vertical plate, the front vertical plate, and the rear vertical plate form a one-way sheet stacking position. Two vertical slide rails 29 are provided on the right side of the one-way sheet stacking position. A connecting plate 30 is slidably connected to the vertical slide rails. A lifting plate 31 is fixedly connected horizontally to the connecting plate. The left side of the lifting plate 31 is located in the one-way sheet stacking position, and the stacked one-way sheets are placed on the lifting plate 31. The lifting motor 25 is located at the lower right side of the lifting plate. A lead screw 32 is connected to the lifting motor. The lead screw is slidably connected to the right side of the lifting plate. The lifting motor drives the lifting plate up and down through the lead screw, thereby driving the stacked one-way sheets to move, ensuring that the suction cup can smoothly absorb the one-way sheets.

[0028] The welding process of one-way sheet is roughly as follows:

[0029] The robot takes the bottom steel and places it on the bottom steel placement rack. The first slide cylinder 17 drives the second slide cylinder 18 to move above the one-way sheet stacking position. There are one-way sheets 24 stacked together in the one-way sheet stacking position. The second slide cylinder 18 drives the pressure plate to move downward. After sucking a one-way sheet through the suction cup, the second slide cylinder 18 drives the pressure plate to move upward. The first slide cylinder 17 drives the second slide cylinder 18 to move, so that the one-way sheet moves to above the foaming agent injection hole 11. The second slide cylinder 18 drives the pressure plate to move downward. The pressure plate presses the one-way sheet on the bottom steel to cover the foaming agent injection hole 11. The laser welding module 15 welds the one-way sheet through the long strip opening 23, welds one side of the one-way sheet to the bottom steel, covers the foaming agent injection hole 11, and the welded bottom steel is taken away by the robot. The above process is repeated to realize automatic welding of the bottom steel and the one-way sheet. After the suction cup absorbs a plurality of one-way sheets, the lifting motor 25 drives the lifting plate to move up via the lead screw, and lifts the stacked one-way sheets 24 so that the suction cup can smoothly absorb the one-way sheets.

[0030] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
