The utility model relates to a kind of hanging device, belong to safety belt hanging technical field, specifically a kind of sliding type safety belt hanging device, including H-shaped steel, further including clamping assembly and fixed component;The clamping assembly includes the U-shaped card of being arranged in H-shaped steel bottom one side, the L-shaped card is arranged in H-shaped steel bottom other side;The fixed component includes the adjusting hole of being opened in U-shaped card one end, the adjusting hole is opened with multiple;The utility model reaches the effect of convenient installation and disassembly, high security, solves the device directly in the existing device between steel column and sets up safety rope, can cause damage to steel surface, increase welding and cutting process;And safety belt hanging is mostly fixed point, when on the steel beam, cannot satisfy the demand of hanging set;If directly using the mode of safety belt around beam, around column, then lead to structure and safety belt wear seriously, security risk is big, not comply with green environmental protection concept problem.

The invention provides a wafer cutting depth control method, a wafer cutting depth control system and a wafer scribing machine, which are used for solving the problem of insufficient cutting depth precision caused by uneven wafer thickness and uneven cutting table surface. The method comprises the following steps: firstly, establishing a fixed compensation relation value between a height measurement value of a cutting knife body and a laser distance measurement value through calibration; secondly, multiple points on the surface of the wafer are scanned through a laser range finder before cutting, and a curved surface model of the surface appearance of the wafer is fitted through an interpolation algorithm; and finally, in the cutting process, the predicted height is obtained from the curved surface model according to the coordinates of the current cutting point, and the position of the cutter body is calculated and adjusted in real time in combination with the fixed compensation relation value and the preset cutting depth. The system comprises corresponding hardware and a control module. According to the method, constant control over the cutting depth is achieved through dynamic compensation, and the precision and consistency of the cutting technology are greatly improved.
