During the rotation of the pulley 206, the connecting belt 207 slides along it, thereby realizing the adjustment of the height of the lifting frame 200.

[0056] Example 3

[0057] Based on Embodiment 1, the door panel quality inspection mechanism 4 includes a sleeve column 400, the bottom of which is slidably connected to a slide rail 401. An electric drive gear 402 is rotatably connected to the bottom of the sleeve column 400. A fixed rack 403 is provided on the inner wall of the slide rail 401.

[0060] The working principle and beneficial effects of the above technical solution are as follows: In use, the door panel on the conveying unit 1 is clamped and flipped to achieve all-round image acquisition of the door panel. Specifically, the lifting cylinder 405 shortens and drives the square column 404 to move downward until the mounting plate 4071 descends to the same horizontal line as the door panel. Then, the hydraulic cylinder 4070 extends and clamps the door panel between the two mounting plates 4071. Then, the miniature bidirectional electric screw 4072 rotates and drives the clamping nut 4073 to move in opposite directions, so that the upper and lower surfaces of the door panel contact the two clamping plates 4074 respectively. Then, the lifting cylinder 405 extends and drives the clamped door panel to move upward, leaving space for flipping. Then, the rotating motor 407 starts and drives the mounting plate 4071 to rotate to achieve the flipping of the door panel. During the flipping process, the image acquisition component performs all-round image acquisition.

[0061] Example 4

[0062] Based on Example 3, the door panel quality inspection and evaluation module includes:

[0063] The manual inspection unit is used to perform preliminary inspections on the door panels, including size inspection, appearance quality assessment and cleanliness assessment, to obtain the sum of several sets of size errors of the door panels (the difference between the preset size and the actual size of the door panel length, width and height), appearance quality coefficient and cleanliness coefficient.

[0064] The evaluation value acquisition unit is used to obtain several door panel size evaluation values, door panel appearance evaluation values, and door panel cleanliness evaluation values ​​based on several sets of results acquired by the image acquisition component and the trained size evaluation model, appearance evaluation model, and cleanliness evaluation model.

[0065] The matrix construction unit is used to construct a door panel quality assessment matrix based on the detection and acquisition results of the manual inspection unit and the evaluation value acquisition unit.

[0066] X= (1);

[0067] Y= (2);

[0068] (3); among which, Here is the door panel quality assessment matrix, where X is the first matrix and Y is the second matrix. This is the sum of the first dimensional errors obtained based on the manual inspection unit. This is the sum of the second dimensional errors obtained based on the manual inspection unit. Based on the sum of the nth dimensional errors obtained by the manual inspection unit, The first appearance quality coefficient is obtained based on the manual inspection unit. The second appearance quality coefficient is obtained based on the manual inspection unit. This is the nth appearance quality coefficient obtained based on the manual inspection unit. The first cleanliness coefficient is obtained based on the manual detection unit. This is the second cleanliness coefficient obtained based on the manual detection unit. The nth cleanliness coefficient is obtained based on the manual detection unit. This is the first door panel size assessment value output by the size assessment model. This is the second door panel size assessment value output by the size assessment model. This is the nth door panel size evaluation value output by the size evaluation model. This is the first door panel appearance evaluation value output by the appearance evaluation model. This is the second door panel appearance evaluation value output by the appearance evaluation model. This is the nth door panel appearance evaluation value output by the appearance evaluation model. This is the first door panel cleanliness assessment value output by the cleanliness assessment model. This is the second door panel cleanliness assessment value output by the cleanliness assessment model. This is the cleanliness assessment value of the nth door panel output by the cleanliness assessment model.

[0069] The comprehensive quality coefficient determination unit is used to determine the comprehensive quality coefficient of the door panel based on the door panel quality assessment matrix.

[0070] In the door panel quality assessment matrix, delete each row element in each first matrix and each column element in the corresponding second matrix to obtain 3 intermediate matrices. Calculate the rank of the 3 intermediate matrices and delete the rank of the 3 intermediate matrices that deviates the most from the average of the rank of the 3 intermediate matrices. Use the average of the ranks of the remaining two matrices as the comprehensive quality coefficient of the door panel.

[0071] The working principle and beneficial effects of the above technical solution: The design of the door panel quality inspection and evaluation module can realize the comprehensive evaluation of the door panel quality. When the comprehensive quality coefficient of the door panel is less than the preset comprehensive quality coefficient of the door panel, it proves that the door panel is unqualified. Otherwise, the door panel is qualified. When the unqualified door panel passes through the mechanical sorting mechanism 5, it is rejected by the mechanical sorting mechanism 5, thereby ensuring the quality of the door panel leaving the factory.

[0072] Example 5

[0073] Based on Embodiment 1, the movable stacking unit 3 includes a stacking frame 300, and a micro electric gear 301 is rotatably connected inside the stacking frame 300. The micro electric gear 301 meshes with the bottom of the partition 302.

[0074] The partition 302 is slidably connected to the stacking frame 300. The partition 302 includes a back plate 303 and a rack plate 304 and a trapezoidal plate 305 installed on the back plate 303. The trapezoidal plate 305 is provided with a negative pressure component 306.

[0075] Preferably, the assembly also includes a stacking and bundling component. The stacking and bundling component includes two symmetrically arranged electric height adjusting screws 307, which are rotatably connected to the stacking frame 300. A height adjusting nut 3070 is threaded onto the electric height adjusting screw 307. An L-shaped mounting plate 3071 is fixedly connected between the two height adjusting nuts 3070. An inlet 3072 is provided on the L-shaped mounting plate 3071. A toggle clamping element 3073 is rotatably connected to the L-shaped mounting plate 3071. A clamping rod 3074 is slidably connected to the L-shaped mounting plate 3071. A clamping elastic element 3075 is sleeved on the clamping rod 3074. A clamping roller 3076 is rotatably connected to the bottom of the clamping rod 3074. A strapping take-up and release component 3077 is installed on the L-shaped mounting plate 3071. The strapping take-up and release component 3077 is used to take up and release straps 3078. Straps 3078 are used to bundle the door panels.

[0076] The working principle and beneficial effects of the above technical solution are as follows: When in use, the electric height adjustment screw 307 rotates and drives the height adjustment nut 3070 to move up and down, so that the bottom of the L-shaped mounting plate 3071 is attached to the rack plate 304 on which the partition 302 is to be placed, so that the door panel slides onto the trapezoidal plate 305 after sliding through the inlet 3072.

[0077] When the next door panel slides into the inlet 3072, the trapezoidal plate 305 causes the next door panel to push the previous door panel upward, thus achieving self-stacking of the door panels. During the stacking process, the clamping rod 3074 gradually moves upward under the push of the door panel. During this process, the clamping elastic element 3075 continuously shortens. Under the action of the clamping rod 3074, the stacked door panels can maintain their position. When the door panel gets stuck or the left side of the door panel is not aligned during the pushing process, the aligning element 3073 is rotated to push the door panel forward or align the left side of the door panel.

[0078] Before the door panels are stacked, the strapping release and take-up assembly 3077 releases the strapping 3078, and at the same time the negative pressure assembly 306 is activated to attract the strapping 3078 onto the trapezoidal plate 305. When the door panels are stacked, the first door panel passes through the strapping 3078. After the last door panel is successfully stacked, the strapping release and take-up assembly 3077 tightens the strapping 3078 and cuts the tightened opening, thereby realizing the automatic stacking and bundling of the door panels.

[0079] The partition 302 can be pushed out or disassembled according to design and usage requirements. Before stacking the partition 302, the stacking and bundling assembly moves upward to directly above the corresponding partition 302.

[0080] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
