[0032] The specific configuration and function of the flip structure 8 and the supporting structure 9 will be described in detail below.

[0033] like Figure 2 and Figure 3As shown, the flip structure 8 includes a fixed plate 801, the fixed plate 801 is fixedly connected to the detection platform 1, a rotating frame 802 is rotatably connected inside the fixed plate 801, two second electric push rods 803 are fixedly connected to the surface of the rotating frame 802, the output end of the second electric push rod 803 is fixedly connected to the clamping plate 804, the surface of the detection platform 1 is fixedly connected to the third electric push rod 805, the output end of the third electric push rod 805 is fixedly connected to the rack 807, the surface of the rotating frame 802 is fixedly connected to the gear 806, the rack 807 is meshed with the gear 806, and the surface of the detection platform 1 is fixedly connected There is a guide plate 808, which is slidably connected to the rack 807. The guide plate 808 guides the sliding path of the rack 807. The surface of the splint 804 is fixedly connected to a support rod 809, which passes through the rotating frame 802. The movement of the splint 804 will drive the support rod 809 to slide along the rotating frame 802, and the support rod 809 supports the splint 804. The surface of the splint 804 is fixedly connected to a rubber pad 810, which prevents the rigid contact between the splint 804 and the workpiece from causing damage to the workpiece.

[0034] like Figure 4 As shown, the support structure 9 includes a U-shaped plate 91, which is fixedly connected to the detection table 1. A second motor 92 is fixedly connected to the surface of the U-shaped plate 91. A threaded rod 93 is fixedly connected to the output end of the second motor 92. The threaded rod 93 is rotatably connected to the U-shaped plate 91. The arc surface of the threaded rod 93 is threadedly connected to a threaded tube 94. The upper end of the threaded tube 94 is rotatably connected to a support plate 95. The lower surface of the support plate 95 is rotatably connected to two rotating plates 96. The lower end of the rotating plate 96 abuts against the surface of the U-shaped plate 91. Four strip plates 97 are fixedly connected to the surface of the U-shaped plate 91. The strip plates 97 are slidably connected to the rotating plates 96. The strip plates 97 limit the moving path of the rotating plates 96, thereby preventing the support plate 95 from rotating with the threaded tube 94. A leaf spring 98 is fixedly connected to the surface of the support plate 95. One end of the leaf spring 98 is fixedly connected to the rotating plate 96.

When the support plate 95 moves to a suitable position, the workpiece is placed on the support plate 95, and then the output end of the second electric push rod 803 is controlled to extend, and the clamping plate 804 will drive the rubber pad 810 to move. When the rubber pad 810 is against the surface of the workpiece, the clamping plate 804 can clamp the workpiece, and the rubber pad 810 prevents the rigid contact between the clamping plate 804 and the workpiece from causing damage to the workpiece. The movement of the clamping plate 804 will drive the support rod 809 to slide along the rotating frame 802, and the support rod 809 can support the clamping plate 804. The output end of the second motor 92 is controlled to rotate in the opposite direction, so that the support plate 95 moves downward and disengages from the workpiece, so as to avoid the support plate 95 interfering with the subsequent turning of the workpiece. Then, the pneumatic slide table 3 is used to drive the bracket 4 to move, and the first motor 6 drives the lead screw 5 to rotate and drive the connecting block 7 to move. The output end of the first electric push rod 10 is extended and retracted to drive the detection head 11 to move. The detection head 11 can be used to perform three-dimensional detection on the workpiece. After the detection is completed, the output end of the third electric push rod 805 is controlled to extend, and the rack 807 slides along the surface of the guide plate 808 to drive the gear 806 to rotate. The guide plate 808 guides the sliding path of the rack 807. The rotation of the gear 806 drives the rotating frame 802 to rotate, and the rotation of the rotating frame 802 drives the second electric push rod 803 and the clamping plate 804 to rotate, and finally drives the workpiece to rotate, so that the workpiece can be turned over without removing the workpiece, thereby facilitating the subsequent detection of the other side of the workpiece, thereby greatly improving the detection efficiency.
