[0012] Compared with the prior art, the present invention has the following beneficial technical effects:
[0013] In use, this utility model has conveying mechanisms on both sides of the device. The packaging boxes are conveyed one by one to the bottom of the conveying component through common structures such as conveyor belts. Then, multiple clamping components clamp the upper half of the packaging box one by one, allowing the detection component to detect the lower half of the packaging box from below. Another conveying component clamps the lower half of the packaging box, and the detection component detects the upper half of the packaging box, realizing the detection of the outer surface of the packaging box, which facilitates the subsequent sorting of the packaging boxes.

[0019] Example 1
[0020] like Figures 1-4 As shown, the defective product packaging box sorting device proposed in this embodiment includes a frame 1, a conveying assembly, and a detection assembly. The frame 1 is provided with a top frame 2, a mounting plate a8, and a mounting plate b9. The top frame 2 is provided with a hydraulic cylinder a3, and a lifting frame 4 is provided at the output end of the hydraulic cylinder a3. One conveying assembly is provided on the lifting frame 4 and one on the frame 1, and the two conveying assemblies are distributed opposite to each other. The conveying assembly includes a hydraulic cylinder b10, two rotating frames 5 arranged side by side, two chains 6 arranged side by side on the two rotating frames 5, a plurality of clamping assemblies 7 evenly arranged on the two chains 6, and a bending plate 11 provided at the output end of the hydraulic cylinder b10. The plurality of clamping assemblies 7 all abut against the bending plate 11. One detection assembly is provided on the mounting plate a8 and one on the mounting plate b9, and the two detection assemblies are distributed opposite to each other. The projection surfaces of the two conveying assemblies partially overlap.
[0021] In this embodiment, conveying mechanisms are set on both sides of the device. The packaging boxes are conveyed one by one to the bottom of the conveying component through common structures such as conveyor belts. Then, multiple clamping components 7 clamp the upper half of the packaging box one by one, allowing the detection component to detect the lower half of the packaging box from below. Another conveying component clamps the lower half of the packaging box, and the detection component detects the upper half of the packaging box, realizing the detection of the outer surface of the packaging box, which facilitates the subsequent sorting of the packaging boxes. The rotation frequency of the rotating frame 5 is distributed by alternating rotation and stop to avoid the influence of inertia on the movement of the packaging box. The hydraulic cylinder a3 can drive one of the conveying components to rise, allowing the device to adapt to packaging boxes of different heights.
[0022] Example 2
[0023] like Figure 4 As shown, this embodiment proposes a sorting device for non-conforming packaging boxes. Compared with Embodiment 1, in this embodiment, the clamping assembly 7 includes a connecting frame 71 disposed on two chains 6, a pushing frame 72 slidably disposed on the connecting frame 71, a roller 73 rotatably disposed on the pushing frame 72, two bending frames 74 rotatably disposed on the connecting frame 71, a clamping frame 75 rotatably disposed on each of the two bending frames 74, and a counterweight 76 disposed on each of the two clamping frames 75. The counterweight 76 is always distributed below the clamping frame 75, so that the end face of the clamping frame 75 is always perpendicular to the ground. The two pushing frames 72 are also provided with abutment frames. When the packaging box is clamped, the abutment frames will contact the upper or lower end of the packaging box to prevent the packaging box from contacting and being damaged by the bending frame 74 during the inspection process.
[0024] The pusher frame 72 has two drive rods arranged side by side. The two drive rods slide in contact with the two bending frames 74 respectively. When the roller 73 drives the pusher frame 72 to rise and fall, the pusher frame 72 drives the bending frames 74 to rotate.
[0025] In this embodiment, when the packaging box moves between the two bending frames 74, the roller 73 drives the bending frames 74 to rotate by pushing the frame 72, so that the clamping frames 75 on the two bending frames 74 rub against the sides of the packaging box, and the device limits the packaging box from both sides to prevent the packaging box from moving randomly and improve the detection accuracy of the packaging box.
[0026] Example 3
[0027] like Figures 1-3 As shown, the defective product packaging box sorting device proposed in this embodiment, compared with the first embodiment, in this embodiment, the rotating frame 5 includes a rotating rod part and two sprocket parts coaxially arranged on the rotating rod part; the clamping assembly 7 is distributed between the two sprocket parts, and the rotating frames 5 of the two conveying components are connected to chain sprocket assemblies. A single drive source drives the two rotating frames 5 to rotate synchronously through the chain sprocket assemblies, thereby improving the conveying accuracy of the device.
[0028] The monitoring component consists of multiple high-resolution cameras facing different directions. These cameras are evenly distributed and photograph the packaging box from multiple angles. The cameras are connected to a central control unit, and the captured images are compared with a normal packaging box model by the central control unit. This allows for the detection of the outer surface of the packaging box, thereby identifying defective boxes and improving the yield rate of sorted packaging boxes.
[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
