[0045] The translation assembly 5 includes two No. 1 guide rails 51, and the two No. 1 guide rails 51 are both installed on the workbench 1 and are parallel to the transmission direction of the transmission belt 8. A No. 1 slider 52 is slidably provided on the two No. 1 guide rails 51, and a No. 1 translation plate 53 is fixedly connected to the two No. 1 sliders 52. A No. 1 motor 54 is installed under the No. 1 translation plate 53 through a fixing part, and a No. 1 gear 55 is fixedly connected to the output shaft of the No. 1 motor 54. A No. 1 rack 56 meshing with the No. 1 gear 55 is provided under the No. 1 gear 55, and the No. 1 rack 56 is installed on the workbench 1.

[0048] During operation, the existing patch processing detection device needs to separate the clamping blocks to both sides and then place the patch between the two for fixation, which makes the detection operation cumbersome. When the number of patches to be inspected is large, the detection time will be long, affecting the detection efficiency. In this solution, in the initial state, the spring 39 will always push the closing plate 34 toward the through groove 32, so that the closing plate 34 is extended and set outside the through groove 32, and the end of the closing plate 34 with the blanking port 35 is against the limit plate 11.

When the closing plate 34 moves, it will slide on the limit rod 38 and squeeze the spring 39 toward the inner wall of the protective shell 33 to make it contract. When the blanking port 35 opened on the closing plate 34 moves into the placement cylinder 31, the patch at the bottom layer of the placement cylinder 31 will fall into the blanking port 35 and fall on the surface of the workbench 1. Then the handle 36 is released. At this time, under the action of the spring 39, the closing plate 34 will return to its original position, so that the closing plate 34 will be against the side of the limiting plate 11 again. At this time, the patch in the blanking port 35 will be pushed out of the placement cylinder 31 through the through slot 32, and when the blanking port 35 is When the material trough 2 is used, the patch located in the material outlet 35 will fall onto the transmission belt 8 through the material trough 2. As the transmission belt 8 is driven, the patch falling thereon will be transported to the bottom of the detection port 4. In the transmission process, the two guide plates 10 will guide and center the patch so that the patch can accurately move to the bottom of the detection port 4. The orientation of the detection probe 6 is adjusted by controlling the translation component 5 and the electric telescopic rod 12. When adjusting, the No. 1 motor 54 is controlled to operate. When the No. 1 motor 54 is operated, the No. 1 gear 55 is driven to rotate. When the No. 1 gear 55 rotates, it will drive the No. 1 translation plate 53 to translate on the No. 1 guide rail 51 through engagement with the No. 1 rack 56. When the No. 2 motor 510 is controlled to operate, it will drive the No. 2 gear 511 to rotate, and the No. 2 gear 5 When 11 rotates, it will drive the second translation plate 59 to translate on the No. 1 translation plate 53 through the engagement with the No. 2 rack 512, and the translation direction of the No. 2 translation plate 59 is perpendicular to the translation direction of the No. 1 translation plate 53. The height of the detection probe 6 can be adjusted by controlling the extension and contraction of the electric telescopic rod 12, so as to adjust the detection and measurement position of the detection probe 6, so as to fully measure the patch through the detection probe 6. The patch measured by the detection probe 6 will fall from the transmission end of the transmission belt 8 as it is conveyed by the transmission belt 8. By pulling the handle 36 again, the patch located at the bottom layer of the placement tube 31 can be discharged from the placement tube 31 for measurement. The cooperation achieves the effect of continuous detection and measurement.
