In particular, it relates to a method for preparing mercury in a small lamp. 5 [Prior art] All the gas discharge lamps or fluorescent lamps currently used are provided with mercury inside the lamp tube. According to the current manufacturing method, the method of making mercury in the lamp tube can be divided into two. Species. The first is the direct drip method. This method is to drop the required amount of liquid mercury directly into the lamp. Although this method seems simple and convenient, there is a hidden problem, which is because of the mercury. The cohesive force is very large, so when the droplets of liquid mercury are dropped, the droplets must be large enough to drip, so this manufacturing method can only be applied to lamps with larger tube diameters. The second is to mix mercury with other metals to make granular solid mercury. 15 Then put the required amount of solid mercury particles in the lamp, and then heat the lamp to achieve the proper amount of mercury solution. Purpose, this method has the disadvantage that mercury must be mixed with other metals to make alloy particles, so its preparation is more complicated and the cost is higher. In addition, because the alloy particles contain other kinds of metals, the temperature required for heating during the process of vaporizing mercury by heating is relatively high, and the cost of other metals will affect the inner wall of the rear lamp tube. Coating quality. Therefore, there is still room for improvement in these two methods.

The syringe includes 5 receiving portions, and one of the receiving portions is provided at one end. There is an injection part at the other end of a pressing part, the containing part is filled with liquid mercury, the injection part is a needle-like body, the glass tube is placed in front of the syringe and the injection part is extended into and close to The inner wall surface of the glass pipe can inject the required amount of liquid mercury into the glass pipe through the injection part, and the glass pipe containing the liquid mercury is placed from the open end of a lamp to be processed into the to-be-processed Inside the lamp tube, then the open end of the lamp tube to be processed is closed, and one end of the glass tube to be processed is heated and cold wind is blown to the other end to cool the liquid in the lamp tube to be processed. Mercury vaporizes and is heated by the end The diffused cooling is performed toward the cooling end. At the same time, the glass tube section of the lamp tube to be processed is cut off after being attached to the inner wall surface of the lamp tube to be processed, and the cut-off lamp tube is sealed to form a desired finished product. [Embodiment] In order to explain the features and effects of the present invention in detail, an embodiment is described in detail below in conjunction with the drawings. 20 The first figure is a schematic view of a glass pipe used in the present invention. The second figure is a schematic view of the glass tube of the present invention placed in front of a syringe. The third figure is a schematic view of the injection part of the syringe projecting into the glass tube in the present invention.

The sixth figure is a schematic view of the lamp tube to be heated in the present invention after being sealed. The seventh diagram is a schematic diagram after the lamp tube of the present invention is completed. In the method for making mercury in a small lamp tube provided by the present invention, please refer to the first to third drawings when manufacturing a lamp. First, a glass tube 10 is taken. The outside diameter of the glass tube is smaller than the inside diameter of the lamp tube. The glass tube is placed in front of a syringe 20, which includes an accommodating portion 21, one end of which is provided with a pressing portion 22, and the other end is provided with an injection portion 23, which is filled with liquid 10 State mercury, the injection portion is a needle-shaped body, the glass tube is placed in front of the syringe and the injection portion is extended into and close to the inner wall surface of the glass tube, and the pressing portion can be connected to an electric motor Automatic control mechanism or stepping mechanism 24, so that the amount of liquid mercury can be automatically controlled more accurately. The pushing portion 22 of the syringe is pushed, so that the liquid mercury 15 in the containing portion 21 can be injected into the glass tube 10 through the injection portion 23, and because the injection portion of the syringe is close to The inner wall surface of the glass tube is attached to the inner wall surface of the glass tube when liquid mercury is squeezed out of the injection part, so there is no problem that the mercury droplets are too small to drip. Then, a lamp tube 30 to be processed is taken. The lamp tube has a closed 20 end 31 and an open end 32. The lamp tube to be processed is provided with a convex portion protruding into the tube at a predetermined distance from the open port thereof. 33. The open end of the lamp tube to be processed is placed in a temperature control tube 40. The temperature control tube has an air extraction end 41. The air extraction end can be connected to an air extraction device, and the air can be continuously extracted to make the object to be processed. The open end 32 of the lamp tube is maintained in a temperature stable state, so that it is contained in the glass tube. 6-200533245 Invention Description Liquid mercury in the stomach will not evaporate in advance due to changes in external environmental temperature. Place a glass tube containing liquid mercury into the tube to be processed from the open end of the tube to be processed. At this time, the glass tube will fall into the tube to be processed and be caught on the convex portion. Will continue to fall. 5 Close the open end 32 of the lamp tube to be processed, and then heat one end 32 of the glass tube containing the lamp tube to be processed, and blow cold air to the other end 31 of the lamp tube to be cooled. Once, the liquid mercury in the lamp tube to be processed will be vaporized by the heating, and the heated end diffuses and cools toward the cooled end, and adheres to the inner wall surface of the lamp tube to be processed. 10) After heating for a predetermined time, cut off the glass tube section from the convex portion of the lamp tube to be processed, and seal the lamp tube to be processed after cutting to form a desired finished product. When the mercury is added in the manufacturing method of the present invention, it is not necessary to make mercury into granules in advance, nor will liquid mercury droplets be too small, cohesive force is too large, and there is no 15 method of dripping, which can clearly improve the past manufacturing This problem is especially true for products with smaller tube diameters, such as PL lamps or cold-cathode tubes. The lamp tube diameter of these products is calculated in mm. With such a small size, it is manufactured according to the present invention. The method is particularly effective in improving such products. 200533245 __ Description of the invention ft stomach [Brief description of the drawings] The first figure is a schematic diagram of a glass tube used in the present invention.
