And the conveyor assembly 212 includes a first conveyor belt 2121, a first driven wheel 2122, a second conveyor belt 2123, a second driven wheel 2124, a first drive motor 2125, and a second drive motor 2126. Wherein a first transmission belt 2121 and a first driven pulley 2122 are correspondingly fitted to an upper portion of the first body 2111, and a second transmission belt 2123 and a second driven pulley 2124 are correspondingly fitted to an upper portion of the second body 2112. Eight first driven wheels 2122 are arranged at intervals along the first direction on the upper portion of the first main body 2111 and on a side corresponding to the second main body 2112; the second driven wheels 2124 include eight second driven wheels 2124, and the eight second driven wheels 2124 are arranged at intervals along the first direction at an upper portion of the second main body 2112 and correspond to a side close to the first main body 2111.

The present embodiment can synchronously drive the first and second conveyor belts 2121 and 2123 to run by the first and second drive motors 2125 and 2126, thereby conveying the glass cover plate 100 in the first direction.
In addition, in this embodiment, the cross-sectional shapes of the first conveyor belt 2121 and the second conveyor belt 2123 are cylindrical strips, and when the glass cover plate 100 is loaded on the first conveyor belt 2121 and the second conveyor belt 2123, the first conveyor belt 2121 and the second conveyor belt 2123 are respectively in line contact with the glass cover plate 100, compared with the surface contact manner, in this embodiment, the large-area contact between the first conveyor belt 2121 and the second conveyor belt 2123 and the glass cover plate 100 is avoided as much as possible, so that the problems of pollution and the like to the glass cover plate 100 due to the large-area contact are avoided, and the cleanness of the glass cover plate 100 is ensured. Meanwhile, by matching with the design structure that the first main body 2111 and the second main body 2112 are relatively parallel and spaced along the first direction, in the actual conveying process, the position right below the glass cover plate 100 is in an empty state, so that the pollution of foreign matters existing on the first main body 2111 and the second main body 2112 to the glass cover plate 100 is further reduced.
As shown in fig. 1 to 3, the glass cover plate 100 is conveyed through the feeding channel 2, and the appearance detection of the two short sides, the two flat sides and the two long sides of the glass cover plate 100 is successively completed. Wherein, glass apron 100 is placed when pay-off passageway 2, certain off normal can take place for the unavoidable position, in this embodiment, glass apron 100's off normal can not cause too big influence to two minor faces and planar outward appearance detection of glass apron 100, but the outward appearance that corresponds two long limits of glass apron 100 detects then can cause great interference, the reason is that glass apron 100's off normal leads to two long limits of the unable accurate shooting of long limit detection mechanism 5 to glass apron 100, and then can't carry out accurate judgement and detect.
In order to solve this problem, as shown in fig. 3, a positioning mechanism 6 is provided in the present embodiment upstream of the long-side appearance detection mechanism 5 on the feed path 2 before the long-side appearance detection is performed. The positioning mechanism 6 is used for readjusting the position of the glass cover plate 100 on the feeding channel 2, so that the glass cover plate 100 is conveyed through the long-edge detection mechanism 5 according to the set position to perform long-edge appearance detection on the glass cover plate 100, and then long-edge appearance detection is accurately completed. The positioning mechanism 6 includes a positioning block 61, a positioning slide block 62, a slide driving motor 63, a slide guiding assembly 64, a first position calibration block 65, and a second position calibration block 66. Specifically, as shown in fig. 3, the first position correcting block 65 is bolted to the first body 2111, the second position correcting block 66 is bolted to the second body 2112, the first and second conveyor belts 2121 and 2123 are located between the first and second position correcting blocks 65 and 66, and the opening between the first and second position correcting blocks 65 and 66 is gradually reduced in the first direction. When the glass cover plate 100 passes between the first position calibration block 65 and the second position calibration block 66, both sides of the glass cover plate 100 may abut against the first position calibration block 65 and the second position calibration block 66, and thus an initial position calibration may be performed.
Further, as shown in fig. 3, waist-shaped holes extending along the second direction are respectively formed in the first position calibration block 65 and the second position calibration block 66, and a fixing bolt is inserted into each waist-shaped hole to fix the positions of the first position calibration block 65 and the second position calibration block 66. Each waist type hole extends along the second direction for during actual assembly, first position calibration piece 65 and second position calibration piece 66 can suitably adjust the fixed position along the second direction respectively, and then change the size of the opening between first position calibration piece 65 and the second position calibration piece 66, can just pass through between first position calibration piece 65 and the second position calibration piece 66 with the glass apron 100 that has different minor face size width.
As shown in fig. 3, downstream of the first position alignment block 65 and the second position alignment block 66 in the first direction, a positioning block 61 and a positioning slide block 62 are further provided. Specifically, the positioning block 61 is bolted to the first body 2111, the positioning slider 62 is slidably disposed on the second body 2112 along the second direction relatively close to or away from the positioning block 61, the positioning slider 62 is fixedly connected to a slider (not shown) of the sliding guide assembly 64, a slide rail (not shown) of the sliding guide assembly 64 is fixedly mounted on the second body 2112 along the second direction, the positioning slider 62 is fixedly connected to an output end of the sliding driving motor 63, and the sliding driving motor 63 can drive the positioning slider 62 to move close to or away from the positioning block 61. After the glass cover plate 100 is subjected to the primary position calibration by the first position calibration block 65 and the second position calibration block 66, and then conveyed between the positioning block 61 and the positioning slide block 62, the glass cover plate 100 triggers a calibration position sensor (not shown) disposed therein, and then a controller (not shown) electrically connected with the calibration position sensor controls the sliding driving motor 63 to drive the positioning slide block 62 to perform a positioning motion which is close to the positioning block 61 and then far away from the positioning block 61, so that the glass cover plate 100 is repositioned by using the side edge of the positioning slide block 62, which is directly opposite to the positioning block 61, as a positioning edge. The displacement stroke of the sliding driving motor 63 can be set by a controller according to the conditions of the glass cover plates 100 with different sizes and widths, so as to adapt to the accurate positioning of the glass cover plates 100 with different sizes and widths.
In addition, in order to avoid the positioning of the positioning block 61 and the positioning slide block 62, the friction force of the positioning block 61 and the positioning slide block 62 against the side of the glass cover plate 100 is too large, which causes scratches. As shown in fig. 3, four positioning block pulleys 611 are rotatably and side by side along the first direction on the side of the positioning block 62 facing the positioning block 61, and four sliding block pulleys 621 are rotatably and side by side along the first direction on the side of the positioning block 62 facing the positioning block 61, so that the positioning block 61 and the positioning sliding block 62 are in rolling contact with the glass cover plate 100, thereby avoiding the influence caused by excessive friction force, finally realizing accurate positioning of the glass cover plate 100, and protecting the quality of the glass cover plate 100.

And the second short edge detection assembly 322 includes a second short edge detection support 3221 and a second short edge detection camera 3222. The bottom end bolt of the second short edge detection support frame 3221 is fixedly mounted on the second short edge detection slider 313, the second short edge detection camera 3222 is mounted on the second short edge detection support frame 3221, and the second short edge detection camera 3222 is aligned to the feeding channel 2 along the third direction to shoot another short edge of the glass cover plate 100. The embodiment realizes the targeted appearance detection of two short sides of the glass cover plate 100 through the first short side detection camera 3212 and the second short side detection camera 3222. Specifically, a short-edge detection position sensor (not shown in the figure) is disposed at a position of the feeding channel 2 where the short edge detection is located, when the glass cover plate 100 moves in the first direction and passes through the position of the short-edge detection position sensor, which indicates that the glass cover plate 100 has reached the position where the short edge detection is performed, the short-edge detection position sensor transmits a signal to the controller, and then the first short-edge detection camera 3212 is controlled to complete appearance detection of one short edge which enters the detection position of the short-edge detection mechanism 3 most recently, and the second short-edge detection camera 3222 is controlled to complete appearance detection of the other short edge of the glass cover plate 100 at the same time.
