CO2 laser light path lens temperature detection and temperature differential overrun alarm system

Abstract

In order to solve problems of reduction of laser outputting power and stability caused by the pollution of the laser lens or burning of the lens, CO(SUB)2( / SUB) laser optical path lens temperature detection and temperature difference over limit alarming system are provided, which are composed of a computer temperature detection and temperature difference over limit alarming module in the signal processing component, an ADAM-4520 module, an ADAM-4018 module and a group of thermoelectricity component and each lens of the laser by electrical connection. The gorge line communication cable transmits the collected temperature signal to computer temperature detection and temperature difference over limit alarming module for calculation and process, and displays water temperature signal of the lens component on the monitor in-real time way. When the temperature difference is over-limit, the sound is alarming. Effects: real-time, rapid, precise detection for working state in the lens of the laser optical path; timely and accurately processing laser polluting alarming. The lens working state is improved and using age is enhanced. Function is stable and suitable for long and continuous detection. The data transmission has long distance, strong resisting disturbance ability, which is easy to operate, friendly interface, convenient to integrate and control the system.

Description

Technical field: [0001] The present invention relates to a CO 2 The lens temperature detection system in the optical path of the laser processing system, especially involving a high-power CO 2 Laser optical path lens temperature detection and temperature difference alarm system. Background technique: [0002] Laser is one of the great inventions of natural science in the 20th century. Since the birth of the world's first laser in 1960, in the past 50 years, laser technology has been widely used in almost all fields of national defense, science and technology, industry, agriculture, medicine, and daily life with its unique characteristics and strong vitality. rapid development and wide application. [0003] On the one hand, the development of lasers is developing in the direction of various types of lasers, such as from the initial Rugby Laser, He-Ne Laser to the current Diode Laser, Carbon Dioxide Laser (CO 2 Laser), argon ion laser (Argon IonLaser), neodymium aluminum ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problem that the above-mentioned laser lens is polluted, the laser output power and stability are reduced and even the lens is burned, the present invention provides a high-power CO 2 A laser optical path lens temperature detection and temperature difference alarm system, the system includes a laser rear reflector assembly (1), a laser resonator (2), a laser output mirror assembly (3), a first-stage right-angle reflector assembly (5), The reflective focusing mirror assembly (6), the second-level right-angle mirror assembly (7) and the electrical connection between them, the system also includes a signal processing assembly (8), and the signal processing assembly (8) is mainly detected by a computer temperature and a temperature difference overrun alarm module (16), an ADAM-4520 module (17), an ADAM-4018 module (18) and a group of thermocouple assemblies (11); the computer temperature detection and a temperature difference overrun alarm module (16) The thermocouple assembly (11) is electrically connected to each lens assembly; and after the water temperature signal collected by the thermocouple assembly (11) is converted to an analog / digital signal by the ADAM-4018 module (18), it is then passed through the ADAM-4520 module ( 17) Carry out RS-323 / RS-485 signal conversion, and then pass the serial port communication cable into the computer temperature detection and temperature difference overrun alarm module (16), and the data is in the computer temperature detection and temperature difference overrun alarm module (16) Perform calculation and processing, and display the water temperature signal on each lens assembly on the monitor in real time, and alarm when the temperature difference exceeds the limit
