AI Technical Summary

Technical Problem

Existing microscope sleeve cutting equipment has uncontrollable cutting quality, poses a risk of burns from residual heat, lacks status perception, and has poor applicability to materials and thicknesses.

Method used

A microscope film cutting system based on tension mutation feedback is adopted. By combining a gripping and stretching module, a thermal cutting module and a mechanical sensing module, a vacuum suction cup and an electric heating wire are used to achieve instantaneous cutting and power cut-off under constant tension, combined with real-time control by a main control microprocessor.

Benefits of technology

It achieves a perfect cut with zero burrs and no wrinkles, avoids the risk of microscopic burns, has wide material applicability and adaptive cutting capabilities, and lowers the operating threshold.

Abstract

The application discloses a surgery room microscope cover film cutting system and method based on tension mutation feedback, which comprises a grabbing and stretching module, a heat cutting module and a mechanical sensing module. The grabbing and stretching module comprises a suction cup and a vacuum source, the vacuum source is connected with the suction cup through a control valve, the suction cup is used for adsorbing and dragging the film backward, and the vacuum source provides adsorption force for the suction cup. The heat cutting module comprises an electric heating wire and a power supply control loop, the electric heating wire is arranged around the periphery of the suction cup and forms a ring, the suction cup adsorbs the film and drags the film backward to the electric heating wire, and the film is attached to the electric heating wire. The mechanical sensing module is connected in series in the transmission or stress path of the grabbing and stretching module, and is used for acquiring the tension F(t) of the film in real time. The main control microprocessor is electrically connected with the control valve, the electric heating wire and the mechanical sensing module. The electric heating wire is instantaneously turned on only when the current F(t) of the film is greater than or equal to the preset optimal cutting tension threshold value, and the high-tension film is cut by heat melting.
