The layer-by-layer polishing observation device for the composite board sample block is further described with reference to the following embodiments:

the working process of the device is realized as follows:

firstly, an operator places and fixes the composite plate sample block on the suction cup 103 of the conveying assembly 1, the asynchronous motor 106 drives the driving chain wheel 109 connected with the asynchronous motor to rotate, the driving chain wheel 109 drives the driven chain wheel 107 to rotate through the chain 105, the driven chain wheel 107 drives the other driven chain wheels 107 to rotate through the chain 105, so that the conveying table 104 moves, and the composite plate sample block moves to a proper position along with the conveying table 104 to prepare for subsequent processes.

Then, the first servo motor 201 and the second servo motor 212 in the feeding assembly 2 respectively drive the transverse screw rod 211 and the longitudinal screw rod 208 to rotate, and the clamp bottom plate 301 in the clamp assembly 3 moves transversely and longitudinally along with the rotation of the screw rods, so that the clamp assembly 3 moves to the position where the composite plate sample block is placed.

When the feeding assembly 2 moves the clamp assembly 3 to the position above the suction cup 103 in the conveying assembly 1, the clamp assembly 3 moves downwards under the action of the hydraulic cylinder 302, the hydraulic cylinder push rod 303 transmits power to the fixing frame 304, the clamp support frame 307 is kept still, the fixing frame 304 slides downwards while the clamp connecting rod 308 moves inwards to drive the clamp 305 to clamp the composite plate sample block, the sensor 309 detects the clamping force at the same time, the composite plate sample block is prevented from being damaged by clamping due to overlarge clamping force, the clamping action of the composite plate sample block is realized, meanwhile, the hydraulic cylinder 302 rotates around the clamp bottom plate 301 in a 90-degree direction, and the transition of the polishing direction in the later period is facilitated.
