In an embodiment, the second clamping plate 2 remains stationary, and the distance between the initial position of the first clamping plate 1 and the second clamping plate 2 is the maximum distance that the clamp can be opened. On this basis, minus the distance that the first plywood 1 moves to the second plywood 2 is the distance between the two end points of the material held by the fixture. If the material is square, the side length of the material is obtained. If it is a circle, find the diameter of the material. This solution can determine the size of the material during the process of clamping the material for feeding.

Further, the driving assembly 5 includes: a driving member 51 , a first sliding rail 52 and a first sliding block 53 , the first sliding rail 52 is arranged on the fixed seat 3 , and the first clamping plate 1 is slidably arranged on the first sliding block 53 through the first sliding block 53 .

This solution can precisely control the relationship between the first clamping plate 1 and the first clamping plate 1 along the direction of the sliding rail. The second clamping plate 2 is close to or away from each other to prevent the first clamping plate 1 from being dislocated during the moving process, which leads to an increase in the error of the detection result of the sensor assembly 4 .

Through the ratio of the tooth pitch of the guide rack 56 and the driven rack 58, the movement distance of the second clamp plate 2 can be determined during the process of detecting the movement distance of the first clamp plate 1, and the first clamp plate 1 and the second clamp plate 2 can be combined. Calculate the initial distance between the first clamping plate 1 and the second clamping plate 2 at the end of the clamping process, so as to determine the size of the material to be clamped. In the setting of the guide rack 56 and the driven rack 58, preferably, the tooth spacing between the guide rack 56 and the driven rack 58 is set to 1:1, then the movement of the first clamping plate 1 and the second clamping plate 2 the same distance. The advantage of this solution is to increase the working state of the clamping structure while accurately calculating the size of the material to be clamped.
