The control of the product is not strict enough, which affects the firmness of the packaging. Especially when the window sticker box is used for food packaging, there are problems such as missing stickers, crooked stickers, and poor firmness of stickers. Therefore, the firmness of the window sticker needs to be tested.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 3 The utility model provides a technical solution: a window sticker box quality inspection device, comprising a conveying platform 10 for conveying the window sticker box, and a detection frame 20 mounted on the unloading end of the conveying platform 10, and the detection frame 20 is inclined. The inclined structure allows the window sticker box to slide freely on the detection frame 20, thereby realizing automatic loading and unloading. A detection port 21 for detecting the firmness of the window sticker box is provided at the center of the detection frame 20, and a movable upper detection cover 22 is provided on the detection frame 20 and above the detection port 21, and the upper detection cover 22 is parallel to the cardboard of the window sticker box and A transparent film encloses a first sealed chamber, an upper detection cover 22 is connected to an output end of a first drive assembly 30 mounted on the detection frame 20, and a first air pressure sensor 23 is provided on the top of the upper detection cover 22; a lower detection cover 24 capable of cooperating with the upper detection cover 22 is provided on the detection frame 20 and below the detection port 21, the lower detection cover 24 and the detection frame 20 and the transparent film on the window box enclose a second sealed chamber, the lower detection cover 24 is connected to an output end of a second drive assembly 40 mounted on the detection frame 20, and a gas injection assembly 50 is provided on the lower detection cover 24.

[0030] An infrared sensor 25 is provided at one end of the top of the detection frame 20 close to the conveying platform 10. The infrared sensor 25 is used to sense the window box, thereby sending a signal to the control system. The infrared sensor 25 is a prior art, and the specific working process is not repeated here. The first drive component 30 and the second drive component 40 are controlled by the control system.

[0031] In some embodiments of the utility model, the gas injection assembly 50 includes an air inlet 51 opened at the bottom of the lower detection cover 24, an air inlet nozzle 52 is fixedly embedded inside the air inlet 51, and the air inlet nozzle 52 is equipped with a pressure regulating valve 53. The air inlet nozzle 52 is connected to a gas storage tank (not shown in the figure) through a soft air pipe, and an air injection hole 54 is built into the lower detection cover 24. The air injection hole 54 is fixedly connected to the air inlet nozzle 52. A second air pressure sensor 55 is provided on the lower detection cover 24. The second sealed chamber is filled with gas through the air injection hole 54. After the air injection is completed, the pressure regulating valve 53 is closed.

[0032] Exemplarily, pressurized gas is injected into the second sealed chamber through the gas injection assembly 50, and the gas pressure in the second sealed chamber is greater than the gas pressure in the first sealed chamber. The pressure difference should not be too large to avoid separation of the transparent film and the cardboard of the window box. If the transparent film and the cardboard of the window box are not firmly pasted, crookedly pasted or not pasted, the pressure in the first sealed chamber will increase and the pressure in the second sealed chamber will decrease in a short time. The pressures of the first sealed chamber and the second sealed chamber can be detected by the first air pressure sensor 23 and the second air pressure sensor 55 respectively, so as to determine the bonding quality between the transparent film and the cardboard of the window box.

[0033] In some embodiments of the present invention, the area of ​​the detection port 21 is smaller than the area of ​​the window box cardboard, the bottom edge of the upper detection cover 22 is pressed on the window box cardboard outside the transparent film, and the area of ​​the bottom of the upper detection cover 22 is larger than the area of ​​the transparent film attached to the window box.

[0034] Through the above technical solution, the upper detection cover 22 can be used to better press and fix the window box, so as to avoid the upper detection cover 22 being too large and unable to press the window box around, resulting in leakage of the two closed chambers during gas injection, affecting the accuracy of the detection.

[0035] In some embodiments of the present invention, the first driving assembly 30 includes a first support frame 31 installed on one side of the detection frame 20, a first hydraulic cylinder 32 is connected below the first support frame 31, and an output end of the first hydraulic cylinder 32 is connected to the top of the upper detection cover 22.

[0036] The upper detection cover 22 is driven to move up and down by the output shaft of the first hydraulic cylinder 32, so as to press and fix the window sticker box.

[0037] In some embodiments of the present invention, the second driving assembly 40 includes a second support frame 41 installed below the detection frame 20 , and a second hydraulic cylinder 42 is provided on the second support frame 41 . The output end of the second hydraulic cylinder 42 is connected to the top of the lower detection cover 24 .

[0038] The lower detection cover 24 is driven to move by the second hydraulic cylinder 42 , so as to facilitate the matching of the lower detection cover 24 with the upper detection cover 23 .

[0039] In some embodiments of the present invention, sealing strips are provided at the bottom of the upper detection cover 22 and the top of the lower detection cover 24. The provided sealing strips make it difficult for outside air to enter during the firmness test, thereby improving the firmness between the upper detection cover 22 and the lower detection cover 24 and the window box.

[0040] In some embodiments of the present invention, leak-proof rubber rings are glued on the inner and outer sides of the air inlet 51 to enhance the sealing effect of the lower detection cover 24 .

[0041] In some embodiments of the present invention, an electric telescopic rod 26 is provided at one end of the detection frame 20 away from the infrared sensor 25 , a push plate 27 is provided at the output end of the electric telescopic rod 26 , and a notch 28 is provided on one side of the detection frame 20 opposite to the electric telescopic rod 26 .

[0042] When the test data exceeds the set range, that is, the posting firmness test does not meet the standard, a signal is sent to the control system, and the control system starts the electric telescopic rod 26. The push plate 27 on the electric telescopic rod 26 pushes the unqualified window sticker box out of the notch 28 for unloading without manual operation, which greatly improves the detection efficiency.

[0043] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
