Then, starting the second electric hydraulic device 47 to automatically control the extension and contraction of the second hydraulic rod 471, which is located outside the movable shaft 472 through the sleeve 473 and is then moved and adjusted.

After the cutting is completed, the electric push rod device 34 of the cut output mechanism 3 is started to automatically control the extension and retraction adjustment of the push rod 341, so that the shaft plate 335 drives the shaft rod 333 to adjust the height. The shaft plate 1 332 and the telescopic rod 334 assist the shaft rod 333 in the lifting and lowering adjustment, so that the roller 2 33 contacts the cut InSb single crystal rod downward. At the same time, the rotation motor 331 is started to automatically control the rotation of the roller 2 33 to output the cut InSb single crystal rod.

[0025] Three-stage height control: The electric push rod device 34 adopts a segmented control algorithm. In the initial stage, it quickly descends at a speed of 20mm / s to 5mm from the surface of the crystal rod. In the second stage, it switches to a low-speed contact of 0.5mm / s. In the third stage, the micro-motion compensation of the telescopic rod 334 is coordinated to ensure zero damage to the crystal after cutting.

Their structures and principles are known to those skilled in the art through technical manuals or conventional experimental methods. The problem solved by the present invention is that the manual pushing method has problems such as large positioning error and easy damage to the surface of the crystal rod. The traditional cutting equipment has defects such as uncontrollable cutting depth and fast blade wear. After cutting, it is difficult to quickly contact the top of the indium antimonide single crystal rod for output, and the processing efficiency is low. The present invention combines the above components with each other. The indium antimonide single crystal rod input mechanism 2 adopts a screw drive and a hydraulic lifting structure to form a lateral precision displacement, synchronous Vertical lifting can realize automatic adaptation to crystal rods of different specifications with high positioning accuracy. The surface of roller 227 is wrapped with a high-elasticity silicone layer. Cooperating with the torque sensing system of drive motor 228, it can automatically adjust the speed and contact pressure according to the diameter of the crystal rod, effectively avoiding scratches on the surface of hard and brittle materials, and making the crystal rod input stable. The cutting processing mechanism 4 is integrated with the lifting adjustment structure and the driving structure to realize automatic flip adjustment and high-speed cutting above the crystal rod. The output mechanism 3 after cutting is automatically controlled by the lifting adjustment drive to control the output of the cut crystal rod, which greatly improves its processing efficiency and has significant technical demonstration value and industrial promotion potential.
