[0013] Compared with the prior art, the present invention provides an outer shell welding device for a food vending machine, which has the following beneficial effects:

[0014] 1. The outer shell welding equipment of a food vending machine sets instructions for the welding mechanism, and when the second cylinder is started, the second rotating rod is pushed to rotate upward around the rotating block six, and the connecting block is pulled by the first rotating rod to flip the through-core plate from a horizontal state to a vertical state, and then the first motor is started to flip the through-core plate from a vertical state to a horizontal state. At this time, the side panel and the rear cover are under the through-core plate, and the flipping of the side panel and the rear cover after inner welding is completed. With the cooperation of the welding mechanism, it is convenient to weld the inner and outer sides of the joint of the side panel and the rear cover, and when the side panel and the rear cover are flipped and ready for outer welding, the gravity of the rear cover itself can be used to detect whether the rear cover after inner welding will fall off the side panel, or whether there is a gap at the joint with the side panel, so as to judge whether the inner welding is reliable, thereby controlling the welding quality.

[0015] 2. The outer shell welding equipment of this food vending machine fixes the rear cover plate to the lower end of the movable plate under the joint clamping of multiple groups of first splints, starts the first cylinder so that its output end pushes the first fixed rod to rotate. During the process, the first connecting rod and the second connecting rod are driven to flip toward the core plate through the connection with the mounting block. After the first connecting rod flips toward the core plate to be parallel to the ground, the movable plate uses its own gravity to make the single-stage electric push rod and the first splint always face downward. At this time, the movable plate carries the rear cover plate to press on the upper end of the side plate, and the first splint is also on the outside of the side plate at the same time, ensuring accurate docking. The splicing of the rear cover plate and the side plate can be quickly completed through the loading mechanism, which saves manpower and improves the splicing accuracy and welding production efficiency.

[0016] 3. In the outer shell welding equipment of the food vending machine, after the movable plate moves the rear cover to the upper end of the side plate through the first clamping plate, when the inner joint of the side plate and the rear cover is welded by the welding mechanism, the movable plate is still pressed on the upper part of the rear cover. The clamping and fixing of the movable plate and the first clamping plate can make the side plate and the rear cover more stable and tight when the inner side is welded first by the welding gun, thereby improving the welding quality and ensuring the welding pass rate of the outer shell of the food vending machine.

[0033] Specifically, the connection through the connecting plate 514 will drive the support rod 515 and the movable plate 518 to move toward the upper end of the storage platform 2.

[0034] In this embodiment, a support rod 515 is commonly provided between the two groups of connecting plates 514, and the outer side of the support rod 515 is rotatably connected to the third rotating ring 516, and the outer side of the third rotating ring 516 is fixedly connected to two groups of fixed plates 517, and the lower ends of the two groups of fixed plates 517 are commonly fixedly connected to a movable plate 518, and the lower end of the movable plate 518 is provided with multiple groups of single-stage electric push rods 519, and the output end of the single-stage electric push rod 519 is fixedly connected to the first clamping plate 520.

[0035] Specifically, the single-stage electric push rod 519 is started to push the first clamping plate 520 to move toward the rear cover plate, and under the joint clamping of multiple groups of first clamping plates 520, the rear cover plate is fixed to the lower end of the movable plate 518, and then the first cylinder 54 is started so that its output end pushes the first fixed rod 57 to rotate.

When the movable plate 518 carries the rear cover plate and presses on the upper end of the side plate, the first clamping plate 520 is also on the outside of the side plate at the same time, thereby ensuring that the rear cover plate and the side plate are accurately docked.

[0036] In this embodiment, the flip mechanism 7 includes two groups of second support plates 71, and the two groups of second support plates 71 are symmetrical to each other. The lower end of the second support plate 71 is fixedly connected to the second bottom plate 6, and the other side of the second support plate 71 is fixedly connected to the first extension plate 72. The inner side of the first extension plate 72 is rotatably connected to the rotating block 3 73, and the front end of the rotating block 3 73 is fixedly connected to the first rotating rod 74. The inner side of the first rotating rod 74 is rotatably connected to the rotating block 4 75. The rear end of the rotating block 4 75 is fixedly connected to the connecting block 76, and the front end of the connecting block 76 is fixedly connected to the rotating block 5 77.

[0037] Specifically, start the second cylinder 713, and under the connection of the fifth rotating ring 714 and the fourth extension plate 716, push the second rotating rod 78 to rotate upward around the rotating block six 79, and at the same time drive the connecting block 76 to move under the connection of the rotating block five 77. At this time, through the pulling of the first rotating rod 74, the connecting block 76 will cause the core plate 718 to flip from a horizontal state to a vertical state, and the side plate and the rear cover plate will also rotate accordingly. Then, just start the first motor 717 to make the core plate 718 continue to flip from a vertical state to a horizontal state.

The upper end of the fourth extension plate 716 is fixedly connected to the second rotating rod 78. The inner side of the connecting block 76 is provided with a first motor 717. The output ends of the two groups of first motors 717 are commonly fixedly connected to a core plate 718. A connecting groove is provided at the upper end of the core plate 718.

[0039] Specifically, starting the single-stage electric push rod 2 719 can make the second clamping plate 720 clamp the side panel, and the flipping mechanism 7 can complete the flipping of the side panel and the rear cover panel after the inner side welding. With the cooperation of the welding mechanism 8, it is convenient to weld the inner and outer sides of the joints of the side panel and the rear cover panel. When the side panel and the rear cover panel are flipped and ready for outer side welding, the gravity of the rear cover panel itself can be used to detect whether the rear cover panel that has been welded on the inner side will fall off the side panel, so as to judge whether the inner welding is reliable.

[0040] In this embodiment, the welding mechanism 8 includes a first threaded rod 81 and a slide rod 82. Both ends of the first threaded rod 81 are fixedly connected to a rotating shaft 1. The outer side of the rotating shaft 1 is rotatably connected to a second fixed block 83. The lower end of the second fixed block 83 is fixedly connected to the second base plate 6. The upper end of the second base plate 6 is provided with a second motor 84. The output end of the second motor 84 is fixedly connected to the rotating shaft 1. Both ends of the slide rod 82 are fixedly connected to a third fixed block 85. The lower end of the third fixed block 85 is fixedly connected to the second base plate 6. The first threaded rod 81 and the outer side of the slide rod 82 are movably connected to a movable box 86. The inner side of the movable box 86 is provided with an opening 1 87 and an opening 2 88. The opening 1 87 and the opening 2 88 are connected to each other. 8 are interconnected, and a second threaded rod 810 is provided on the inner side of the opening 1 87. The front and rear ends of the second threaded rod 810 are fixedly connected with the rotating shaft 2, and the rotating shaft 2 is rotatably connected to the moving box 86. A third motor 89 is installed on the outer side of the moving box 86, and the output end of the third motor 89 is fixedly connected to the rotating shaft 2. The outer side of the second threaded rod 810 is threadedly connected with a moving block 811, and the other side of the moving block 811 is fixedly connected with a sliding rod 2 812, and the sliding rod 2 812 is slidably connected to the inner side of the opening 2 88. A fourth motor 813 is provided on the upper end of the moving block 811, and the output end of the fourth motor 813 is fixedly connected to a multi-stage electric push rod 814, and the output end of the multi-stage electric push rod 814 is provided with a welding gun 815.

[0041] Specifically, the first threaded rod 81 is rotated by starting the second motor 84, and the movable box 86 with the welding gun 815 is moved to the bottom of the side panel by the action of the screw principle. The welding gun 815 is moved upward to the inner junction of the side panel and the rear cover by starting the multi-stage electric push rod 814. Then the third motor 89 is started to rotate the second threaded rod 810, and the movable block 811 is continued to carry the welding gun 815 from front to back at the inner junction of the side panel and the rear cover by the screw principle. Under the basic operation of this principle, the welding mechanism 8 enables the welding gun 815 to move along the inner and outer sides of the side panel, thereby completing the inner and outer welding of the side panel and the rear cover.

[0042] When in use, under the output of the first cylinder 54, the first connecting rod 510 and the second connecting rod 513 are first placed in a state perpendicular to the ground, the rear cover is placed on the upper end of the storage table 2, and the rear cover is placed between the multiple groups of enclosures 4, and then the side panels are placed in the connecting grooves opened on the core plate 718, and then the splicing operation of the rear cover and the side panels is started, and the first cylinder 54 is started to shrink the output end of the first cylinder 54. When the output end of the first cylinder 54 shrinks, the first fixing rod 57 can be pulled to rotate around the rotating block 2 58 through the connection between the second swivel 55 and the rotating block 1 56. At the same time, under the rotation connection of the second fixing rod 59 and the mounting block 511, the first connecting rod 510 and the second connecting rod 513 are pulled together toward the storage table 2. The direction is flipped. At this time, the connection through the connecting plate 514 will drive the support rod 515 and the movable plate 518 to move toward the upper end of the storage platform 2. During the transfer process, the movable plate 518 is rotated and connected to the support rod 515 under the action of the third rotating ring 516, and through its own gravity, the single-stage electric push rod 1 519 and the first clamping plate 520 are always facing downwards, and when the first connecting rod 510 is flipped toward the direction of the storage platform 2 to be parallel to the ground, the movable plate 518 moves to the upper end of the rear cover, and the first clamping plate 520 moves to one side of the rear cover, and then the single-stage electric push rod 1 519 is started to push the first clamping plate 520 to move toward the rear cover, and under the joint clamping of multiple groups of first clamping plates 520, the rear cover is fixed to the lower end of the movable plate 518. Then, the first cylinder 54 is started to make its output end push the first fixing rod 57 to rotate. The first fixing rod 57 is subjected to the thrust and rotates around the rotating block 2 58 in the direction of the core plate 718. During the process, the second fixing rod 59 is connected to the mounting block 511, and the first connecting rod 510 and the second connecting rod 513 are driven to flip in the direction of the core plate 718. After the first connecting rod 510 flips in the direction of the core plate 718 to be parallel to the ground, the movable plate 518 brings the rear cover to be pressed on the upper end of the side plate, and the first clamping plate 520 is also at the outer side of the side plate at the same time. Then, the single-stage electric push rod 2 719 is started to make the second clamping plate 720 clamp the side plate, and then the welding of the inner side of the junction of the rear cover and the side plate can be carried out. By starting the second The second motor 84 rotates the first threaded rod 81, and under the action of the screw principle, the movable box 86 moves with the welding gun 815 to the bottom of the side panel, and by starting the multi-stage electric push rod 814, the welding gun 815 moves upward to the inner junction of the side panel and the rear cover, and then the third motor 89 is started to rotate the second threaded rod 810, and the movable block 811 continues to carry the welding gun 815 from front to back at the inner junction of the side panel and the rear cover through the screw principle. Under the basic operation of this principle, the welding mechanism 8 moves the welding gun 815 along the inner side of the side panel to complete the inner welding of the side panel and the rear cover. When it is necessary to weld the outer junction of the side panel and the rear cover, the movable plate 518 is transferred to the upper end of the storage table 2, and then the second cylinder 713 is started.Under the connection between the fifth rotating ring 714 and the fourth extension plate 716, the second rotating rod 78 is pushed to rotate upward around the rotating block 6 79. At the same time, under the connection with the rotating block 5 77, the connecting block 76 is moved. At this time, the pulling of the first rotating rod 74 causes the connecting block 76 to flip the core plate 718 from a horizontal position to a vertical position, and the side panels and rear cover also rotate accordingly. Then, it is only necessary to start the first motor 717 to make the core plate 718 continue to flip from a vertical position to a horizontal position. At this time, the side panels and rear cover are located below the core plate 718. Then, it is only necessary to continue to input commands to the second motor 84 and the third motor 89 to make the welding gun 815 weld around the outer connection between the side panels and the rear cover.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
