Cutter special for mercury emission getter sleeve

Abstract

The invention discloses a special cutting machine used for a mercury releasing getter sleeve. The special cutting machine includes a pedestal. The special cutting machine is characterized in that a hitch feed mechanism, a main shaft clamping mechanism and a lift-out cutting mechanism are sequentially arranged on the pedestal; the main shaft clamping mechanism clamps the sent sleeves for cutting; the lift-out cutting mechanism cuts the sleeves into mercury releasing getter finished products; the special cutting machine can adopt the combination of machine, electricity and gas, and realize automation under the program control; the cutting speed thereof is high, and the cut and formed mercury releasing getter has good quality.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a special cutting machine used for mercury releasing getter sleeves. Background technique [0002] Various fluorescent lamps, energy-saving lamps and cold cathodes are more and more widely used, especially in a large number of backlight sources such as LCD TVs, LCD computer monitors and mobile phone LCD screens. In the traditional production process, it is necessary to inject liquid mercury into the lamp tube. In the traditional production process, liquid mercury is dripped into the tube when the lamp tube is exhausted. There are some disadvantages in this manual mercury injection method, because the weight of each drop of mercury ranges from tens of milligrams to one hundred milligrams, which not only makes the accuracy of the control of the amount of mercury dripped relatively poor, but also consumes a lot of mercury, and it will cause argon filling. Fluctuations in pressure have an adver...

Problems solved by technology

There are some disadvantages in this manual mercury injection method, because the weight of each drop of mercury ranges from tens of milligrams to one hundred milligrams, which not only makes the accuracy of the control of the amount of mercury dripped relatively poor, but also consumes a lot of mercury, and it will cause argon filling. Fluctuations in pressure adversely affect lamp performance and life

The more serious problem is that it will cause environmental pollution and directly endanger the health of operators. After the lamp life ends, a large amount of mercury will remain, which is also an important pollutant that endangers the environment.

With the increasingly stringent environmental protection awareness and requirements at home and abroad, the domestic light source manufacturing processes will successively eliminate the liquid mercury drop technology and replace it with solid amalgam powder. A new type of mercury release getter has emerged. The process flow is: Put the amalgam powder into the metal casing first, and then make the finished product through the cutting process. In the process of cutting the finished product of the casing filled with the amalgam powder, there is currently no relevant special equipment
