[0040] The specific working process of this utility model:

[0041] When in use, start the conveying device 2, so that the ceramic sheet 9 is conveyed on the conveying device until the ceramic sheet 9 passes through the positioning component 22, and the ceramic sheet 9 contacts the photoelectric sensor 221 of the positioning component 22, and the positioning component 22 is started, that is, the photoelectric sensor 221 sends a signal to the blocking cylinder 222, and the blocking cylinder 222 rises to block the ceramic sheet 9. At this time, the ceramic sheet 9 is just under the detection camera 21, and the detection camera 21 is used to detect one side of the ceramic sheet 9. After the ceramic sheet 9 passes the detection camera 21, if it is qualified, the blocking cylinder 222 of the positioning component 22 descends, and the conveying device 2 continues to drive the ceramic sheet 9 until the ceramic sheet 9 passes through the positioning component 3 24, and the positioning component 3 24 senses The ceramic sheet 9 is started to block the movement of the ceramic sheet 9, and the ceramic sheet flipping device 4 is started. The flipping motor 41 drives the vacuum suction cup 2 44 to engage with the ceramic sheet 9 through the flipping arm 42, and then the ceramic sheet 9 is flipped to the top of the conveying device 2 3 by flipping the flipping motor 41. The vacuum suction cup 2 44 releases the ceramic sheet 9 and conveys it on the conveying device 2 3. Then the flipping motor 41 resets the flipping arm 42 to the side close to the conveying device 1 2. When the ceramic sheet 9 is conveyed to pass through the positioning component 4 33, the positioning component 4 33 starts to block the movement of the ceramic sheet 9, and then the detection camera 2 31 detects the other side of the ceramic sheet 9. If the other side of the ceramic sheet 9 is qualified, the conveying device 2 3 continues to convey the ceramic sheet 9 to the finished product area.

[0042] If the ceramic sheet 9 on the conveying device 2 is unqualified after being detected by the detection camera 21, when the ceramic sheet 9 passes through the positioning component 23, the positioning component 23 blocks the movement of the ceramic sheet 9, and the lifting cylinder 62 drives the vacuum suction cup 1 64 on the suction cup mounting plate 1 63 to suck the ceramic sheet 9, and then the linear module 61 is started, and the linear module 61 drives the lifting cylinder 62 to slide to the top of the waste box 5, and the lifting cylinder 62 descends, and the vacuum suction cup 1 64 releases the ceramic sheet 9 to the waste box 5, and then the rejection device 6 is reset to the top of the conveying device 2 to complete the rejection of the unqualified ceramic sheet 9;

[0043] If the other side of the ceramic sheet 9 on the conveying device 2 3 fails the inspection after being inspected by the inspection camera 2 31, the unqualified ceramic sheet 9 will be removed, and the alarm indicator light 7 will be set with different colors to indicate whether the inspected ceramic sheet 9 is qualified. The LCD screen 8 will be set to facilitate the operation and observation of the inspection of the ceramic sheet 9.

[0044] By setting a detection camera 1 21 on the conveying device 1 2, setting a detection camera 2 31 on the conveying device 2 3, and setting a ceramic sheet flipping device 4 between the conveying device 1 2 and the conveying device 2 3, the detection and flipping of the ceramic sheet 9 are automatically completed, and the unqualified ceramic sheet 9 is transported to the waste box 5 through the setting of the rejection device 6. The detection of both sides of the ceramic sheet 9 and the rejection of the unqualified ceramic sheet 9 do not require manual operation, and the detection efficiency of the ceramic sheet 9 is high;

[0045] By setting the positioning component 1 22 on the conveying device 1 2 and the positioning component 4 33 on the conveying device 2 3, the positioning of the ceramic sheet 9 is more accurate, and the detection accuracy of the detection camera 1 21 and the detection camera 2 31 on the ceramic sheet 9 is improved, and the detection effect of the ceramic sheet 9 is better;

[0046] The linear module 61 of the rejection device 6 drives the lifting cylinder 62 to move through the slider, and the unqualified ceramic pieces 9 are transported to the waste box 5 through the vacuum suction cup 64 on the lifting cylinder 62. In conjunction with the positioning component 23 on the conveying device 2, the rejection efficiency of the unqualified ceramic pieces 9 is high, thereby improving the detection efficiency of the ceramic pieces 9.
