Description

Technical Field

[0001] This utility model relates to the technical field of CRT pipe diameter cutting devices, and in particular to a CRT pipe diameter cutting device. Background Technology

[0002] In the fields of electronic equipment manufacturing and waste electronic and electrical appliance recycling, CRT applications and subsequent processing have always occupied an important position. Although flat panel display technology has become mainstream, CRT is still used in specific scenarios, and the recycling and dismantling of a large number of waste CRT devices is urgent. In this process, the cutting of CRT tubes faces many challenges, and high-performance cutting equipment is urgently needed to meet industry needs. In the early production of CRT monitors and television equipment, it was necessary to precisely cut and process CRT tubes of different specifications to adapt to the installation and connection of various electronic components. The tubes needed to be precisely connected with electron guns and fluorescent screen components. This required that the cut tube ends be flat and the dimensions accurate, with deviations controlled within a very small range. Generally, the diameter deviation needed to be controlled within one centimeter; otherwise, it would affect the overall performance of the electronic equipment, such as unstable electronic signal transmission and image display defects.

[0003] Currently, pipe cutting devices on the market mainly consist of a cutting execution module and a tool drive system. Traditional CRT pipe cutting often uses manual sawing, which is labor-intensive and slow. For example, a skilled worker can only cut five to eight ordinary CRT pipes per hour, and the cutting accuracy depends on the worker's experience, making it difficult to guarantee consistency. The cut pipe ends often have unevenness and serrations, requiring extensive grinding processes, which is not only time-consuming but also prone to damaging the pipes, affecting subsequent recycling and disposal. In large-scale production and recycling operations, manual cutting simply cannot meet the efficiency requirements. At the same time, there is a lack of cutting devices specifically designed for the characteristics of CRT pipes. CRT pipes are made of special materials, mostly leaded glass, which has different hardness and brittleness than ordinary glass, making it difficult for ordinary cutting equipment to adapt. Although laser cutting equipment has high precision, when used for CRT pipe cutting, the laser energy can easily cause stress concentration inside the leaded glass, leading to pipe breakage. Utility Model Content
