The pinhole detection unit can detect whether the aluminum foil lunch box has pinholes, so as to prevent the aluminum foil lunch box from leaking during use and affecting normal use; an appearance detection unit, which is arranged on the conveying frame 1 and is used to detect the appearance of the aluminum foil lunch box. The inner and outer walls of the aluminum foil lunch box can be inspected to find out whether there are bulges or grooves on the appearance of the aluminum foil lunch box, or the presence of other debris, which helps to improve the quality of the aluminum foil lunch box; a dividing plate 2 is rotatably arranged on the conveying frame 1, and when the conveying frame is A first motor for driving the indexing plate 2 to rotate is fixedly provided at the bottom of the frame 1. A plurality of placement slots 201 are evenly arranged on the indexing plate 2. The placement slots 201 are arranged in two to ten groups. Here, we prefer six groups, which correspond to the loading area 101, the first detection area 102, the first discharge trough 103, the second detection area 104, the second discharge trough 105 and the discharge trough 106. That is to say, the indexing plate 2 rotates 60 degrees in a fixed direction and stops for a certain period of time. At this time, the stamped aluminum foil lunch box will first fall into the placement slot 201 in the loading area 101. In this process, it is necessary to ensure that the lunch box The mouth of the box faces downward and enters the placement slot 201 to cover the loading area 101, and then the dividing plate 2 rotates 60 degrees. At this time, the current lunch box will be transferred from the loading area 101 to the first detection area 102 for pinhole detection. After the detection is completed, it continues to rotate 60 degrees in the same direction, and so on. During the feeding process, the material is detected, rejected and stacked, which can ensure product quality and help improve packaging efficiency; a limit frame 8 is fixedly set on the conveying frame 1, and a discharge chute 106 is opened on the conveying frame 1. The top of the limit frame 8 is connected to the discharge chute 106, and a lifting device is set in the limit frame 8. The receiving plate 801 is provided with a cylinder or a fourth motor in the limit frame 8 for driving the receiving plate 801 to rise and fall. Here, we prefer the fourth motor, and a third screw is fixedly provided at the output end of the third motor to thread the receiving plate 801 to the third screw. When in use, products that have passed two tests will enter the discharge chute 106, and then fall from the discharge chute 106 onto the receiving plate 801 in the limit frame 8. When a product is piled on the receiving plate 801, the receiving plate 801 moves downward a certain distance to realize the stacking of the products from bottom to top, which is convenient for subsequent packaging and improves the use effect.

[0025] During use, by fixing a detection box 3 on the conveying rack 1, fixing a first detection camera 301 in the detection box 3, and fixing an illumination lamp 302 at the first detection area 102, the aluminum foil lunch box can be detected for pinholes to prevent the presence of small holes in the aluminum foil lunch box, which affects the product quality; by fixing a second bracket 5 on the conveying rack 1, and fixing a second detection camera 501 on the second bracket 5, the appearance of the aluminum foil lunch box can be easily inspected, and the rotating cylinder 701 is used to drive the aluminum foil lunch box to flip, so that the outer wall and inner wall of the aluminum foil lunch box can be inspected in turn, thereby improving the inspection effect and ensuring product quality.

[0026] Reference Figure 1 A loading area 101, a first inspection area 102 and a second inspection area 104 are fixedly provided on the conveyor frame 1, the pinhole detection part is fixedly provided at the first inspection area 102, the appearance detection part is fixedly provided at the second inspection area 104, and a first discharge trough 103 is provided between the first inspection area 102 and the second inspection area 104, and a second discharge trough 105 is provided between the second inspection area 104 and the discharge trough 106. The loading area 101, the first inspection area 102, the first discharge trough 103, the second inspection area 104, the second discharge trough 105 and the discharge trough 106 are equidistantly distributed in a clockwise direction.

[0027] Reference Figure 1 , baffles 402 are slidably provided in the first discharge trough 103 and the second discharge trough 105, and a first bracket 4 is fixedly provided on the conveying rack 1, and two groups of first brackets 4 are correspondingly provided. First cylinders 401 for driving the baffles 402 to slide are respectively fixedly provided on the two groups of first brackets 4. When in use, baffles 402 are slidably provided in the first discharge trough 103 and the second discharge trough 105, and then the first cylinder 401 is used to drive the corresponding baffles 402 to slide. When the product is unqualified after inspection and enters the first discharge trough 103 or the second discharge trough 105, the first cylinder 401 can drive the corresponding baffle 402 to slide, so that it slides out of the first discharge trough 103 or the second discharge trough 105. At this time, the lunch box loses the support of the baffle 402 and will enter the unqualified product frame below the conveying rack 1. The unqualified products can be removed in time, thereby improving the use effect.

[0028] Reference Figure 2The pinhole detection unit can use airtight detection or water test to detect whether the aluminum foil lunch box has pinholes. Here, we design the pinhole detection unit according to actual usage: a detection box 3 is fixedly provided on the conveying rack 1, and an irradiation lamp 302 is fixedly provided at the first detection area 102. A first detection camera 301 is fixedly provided on the inner top of the detection box 3, and a rubber pad 303 is fixedly provided on the bottom of the detection box 3. The end face of the rubber pad 303 away from the detection box 3 is against the top of the dividing plate 2. When in use, the aluminum foil lunch box enters the first detection area 102. At this time, the irradiation lamp 302 can be turned on to irradiate the inner wall of the lunch box. The first detection camera 301 is turned on to observe whether there is a bright light spot on the outer wall of the aluminum foil lunch box. If it exists, it means there is a pinhole. Otherwise, there is no pinhole. The detection is convenient and fast, and will not cause pollution to the aluminum foil lunch box, thereby improving the use effect.

[0029] Reference Figure 1 and Figure 3 , the appearance inspection part can be observed by human eyes. Here we design the appearance inspection part as follows: a second bracket 5 is fixedly provided on the conveying frame 1, wherein a second inspection camera 501 is fixedly provided on the second bracket 5, a fixing plate 6 is fixedly provided on the conveying frame 1, a mounting seat 601 is slidingly provided on the fixing plate 6, a connecting seat 7 is lifted and lowered on the mounting seat 601, and a rotating cylinder 701 is fixedly provided on the connecting seat 7, and the rotation angle of the output end of the rotating cylinder 701 is selected to be 180 degrees, which can drive the aluminum foil lunch box to rotate 180 degrees, so that the second inspection camera 501 can inspect the outer wall and the inner wall of the lunch box in turn, and a suction cup 702 is fixedly provided at the output end of the rotating cylinder 701, and the suction cup 702 is tilted at a certain angle for easy suction on the inclined surface at one end of the lunch box. When in use, When the lunch box moves to the second detection area 104, the second detection camera 501 is turned on to detect the outer wall of the lunch box. After the outer wall detection is completed, the mounting base 601 slides toward the lunch box, so that the suction cup 702 sucks the lunch box, and then the connecting base 7 brings the rotating cylinder 701 and the suction cup 702 to rise along the mounting base 601, so that the lunch box is away from the placement slot 201. Then the rotating cylinder 701 is started to rotate its output end 180 degrees, which can turn the lunch box over. At this time, the mouth of the lunch box is facing up, and then the connecting base 7 slides downward to place the lunch box in the placement slot 201 in the second detection area 104. The mounting base 601 slides away from the lunch box. At this time, due to the obstruction of the conveying rack 1, the lunch box is separated from the adsorption of the suction cup 702. At this time, the second detection camera 501 can detect the inner wall of the lunch box to improve the use effect.

[0030] Reference Figure 4A second cylinder 9 is fixedly provided on the limit frame 8, and a push plate 901 is slidably provided in the limit frame 8. The push plate 901 is fixedly connected to the output end of the second cylinder 9. When in use, when it is detected that the number of lunch boxes stacked on the receiving plate 801 reaches the requirement, the second cylinder 9 drives the push plate 901 to extend, and the lunch boxes stacked on the receiving plate 801 can be pushed out, which is convenient for workers to pack them and improves the use effect.
