Description
The present invention relates to a discharge tube joining apparatus for an excimer lamp, and more particularly, to an apparatus for joining a discharge tube of an excimer lamp, To a discharge tube joining apparatus of an excimer lamp having a coaxial double tube structure capable of joining a lamp tube and a lamp tube.
Excimer is an abbreviation of excited state of dimer or extremely short excited dimer. It is also called hetero excimer or exciplex. That is, it refers to a dimer present in the excited state.
For example, when xenon (Xe) gas is subjected to a high-energy impact, the excited electrons are excited in the ground state, and after releasing energy in the excited state, the xenon atoms return to the ground state, . When xenon gas is excited, it becomes a dimer, a two-atom molecule with two atoms in a monomolecular molecule. This xenon dimer does not exist as a dimer, but it returns to its monomer state after one billionth of a second. In general, low-pressure UV light is emitted at wavelengths of 253.7 nm and 184.9 nm, and 184.9 nm decomposes organic impurities at an energy of 154.7 kcal / mol.
However, a liquid crystal display (LCD) substrate, a wafer surface, a polyvinyl chloride (PVC), a polypropylene (PP), a polyethylene (PE), a polyethylene terephthalate (PET), a polystyrene Impurities having a double bond or a triple bond are distributed on the surface of the light-emitting layer, and a C = C bond having a binding energy of 140.5 kcal / mol or a C = O bond having a binding energy of 190 kcal / mol It is impossible. Accordingly, excimer lamps capable of intensively irradiating ultraviolet (UV) rays having a shorter energy than the general UV lamps can be applied to display industries such as liquid crystal displays, wafers, organic light emitting diodes (OLEDs) , And is used in the engineering plastics industry.
In the excimer lamp, an inner tube made of synthetic quartz glass and an outer tube are coaxially arranged to form a discharge tube with a double tube structure. Both ends of the inner tube and the outer tube are closed to be sealed, and a discharge space is formed therebetween And a discharge gas is sealed in the discharge space.
The inner tube and the outer tube are joined to each other by opening both ends of the inner tube outward.
However, when the length of the discharge tube is prolonged, a member is applied between the inner and outer tubes to prevent the shaft from being fixed and the inner tube to rupture, and then the bonding process is performed. Thus, There is a disadvantage that the manufacturing process of the semiconductor device becomes complicated and difficult.
SUMMARY OF THE INVENTION [0008] Accordingly, it is an object of the present invention to solve the above-mentioned problems, and it is therefore an object of the present invention to provide a chuck which is clamped at both ends of an inner tube by two chucks disposed on both sides using three coaxial chucks, Wherein the outer tube is contracted while both ends of the outer tube are clamped, so that the outer tube is joined together.
According to an aspect of the present invention, there is provided a discharge tube joining apparatus for an excimer lamp which clamps an inner tube and an outer tube constituting a discharge tube in a state coaxial with each other and joins both ends of the inner tube and the outer tube, A first inner tube fixture having a first chuck for clamping one end thereof, a second chuck for clamping the other end of the inner tube in a state of being coaxial with the first chuck, And an outer tube holder which is provided between the first and second inner tube holders and clamps the outer diameter of the outer tube in a state of being coaxial with the first and second holders.
The present invention is characterized in that all three chucks are coaxially arranged so that both ends of the inner tube are clamped on two chucks disposed on both sides and one chuck disposed in the center is connected to an outer tube The inner and outer pipes can be fixed while maintaining the coaxial state without using a separate member so that the inner and outer pipes can be joined to each other, There is no reason to consider the additional process, and the manufacturing process of the discharge tube can be simplified.
1 is a view showing a discharge tube structure of an excimer lamp manufactured by a discharge tube joining apparatus of an excimer lamp of the present invention.
2 is a view showing the structure of a double tube welding apparatus of an excimer lamp according to the present invention.
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following detailed description, only two embodiments of the present invention will be described in order to achieve the above-mentioned technical problems. And other embodiments which may be presented by the present invention are replaced by descriptions in the constitution of the present invention.
In the present invention, three coaxial chucks are arranged, and both ends of the inner tube are clamped on the two chucks disposed on both sides of the chucks, and one chuck disposed in the center is arranged on the outer side It is possible to keep the inner and outer pipes in a fixed state while coaxially arranging them without using a separate member. In this state, both ends of the outer pipe are contracted and joined to the outer surfaces of both ends of the inner pipe, Which is capable of manufacturing a discharge tube of an excimer lamp having a structure of an excimer lamp.
The discharge tube of the excimer lamp manufactured through the above bonding apparatus does not need to use a separate member as mentioned above, so there is no reason to consider the process of separating the member after the inner and outer pipes are joined, Can be simplified.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
