In some embodiments, the workpiece 500 has an arcuate surface, and the detection part 520 in the workpiece 500 that needs to be inspected is just located on the arcuate surface , so when the workpiece 500 is placed on the jig assembly 400 , the normal direction of the geometric center of the detection part 520 is inclined to the bearing surface of the jig assembly 400 . Therefore, in order to enable the first detection part 210 to better acquire the image of the detection part 520 and the second detection part 220 to accurately measure the height difference between the detection part 520 and other parts, in some embodiments, the first detection part 520 A detection part 210 and a second detection part 220 are arranged parallel to the normal direction of the geometric center of the detection part 520 , and a detection part and a second detection part 220 are opposite to the detection part 520 , which can be understood as the first detection part 210 and the second detection part 220 . When the second detection part 220 detects the detection part 520 , it is arranged coaxially with the detection part 520 , so that the first detection part 210 can always keep the normal direction of the geometric center of the detection part 520 under the action of the first driving part 230 . The second detection part 220 can always move in a direction perpendicular to the normal direction of the geometric center of the detection part 520 under the action of the first driving part 230 and the second driving part 240 .

Further, in the process of driving the second detection member 220 to move along the second direction 620 by the second driving member 240 , in order to improve the detection accuracy of the second detection member 220 , the second direction 620 should be perpendicular to the geometry of the detection part 520 .

The two driving members 240 can drive the second moving base 290 to drive the second detecting member 220 to move relative to the second base 280 along the second direction 620 .

It can be understood that when the first detection component 210 is a CCD detection camera, the field of view that it can detect is relatively large, so the CCD detection camera can still acquire the image of the detection part 520 completely without moving in the second direction 620 . However, in some embodiments, in order to make the detection assembly 200 more compact, the first detection member 210 can also be disposed on the second base 280, that is, arranged in parallel with the second detection member 220, and the second detection member 220 can be driven synchronously The first detection member 210 and the second detection member 220 move.

On the sliding rail 443 , when the second driving member 240 works, the second moving base 290 slides along the sliding rail 443 . The movement of the second moving base 290 along the sliding rail 443 under the driving of the second driving member 240 can improve the stability of the movement of the second moving base 290 , which is beneficial to improve the detection accuracy of the second detecting member 220 .

In addition, in this application, in order to precisely control the position where the second driving member 240 drives the second detecting member 220 to move, the second driving member 240 may use a screw motor.

The detection part 520 is detected, and the first detection part 210 and the second detection part 220 are arranged parallel to the normal direction of the geometric center of the detection part 520, but each time the workpiece 500 is carried on the jig assembly 400, it cannot be guaranteed The normal direction of the geometric center of the detection part 520 of each workpiece 500 is parallel to the first detection part 210 and the second detection part 220, so it is necessary to obtain the image of the workpiece 500 again through the third detection part 310.

Preferably, the third detection member 310 and the bearing surface of the fixture assembly 400 are arranged parallel to each other, that is, the third detection member 310 is arranged in parallel with the workpiece 500 body, and the image of the workpiece 500 obtained by the third detection member 310 is compared with the preset The amount of displacement of the workpiece 500 can be obtained by comparing the images of the workpiece 500 , and then the image of the detection portion 520 acquired by the first detection member 210 is compensated by the control component.

Further, the detection assembly 200 further includes a third driving member 320 , the third driving member 320 is drivingly connected with the third detection member 310 , and is used for driving the third detection member 310 to move along the third direction 630 to make the third detection member 310 The workpiece 500 can be approached or moved away.

Specifically, the image of the workpiece 500 acquired by the third detection part 310 is used to compensate the image of the workpiece 500 acquired by the first detection part 210, so the image of the workpiece 500 acquired by the third detection part 310 has higher accuracy requirements, Therefore, the third detection member 310 needs to be driven by the third driving member 320 to move along the third direction 630 , so that the third detection member 310 can acquire one or more images of the workpiece 500 with higher precision.
