Automatic exhausting machine of electrodeless lamp

Abstract

An automatic exhausting machine of an electrodeless lamp comprises: a rack, a center disc installed on the rack, an oven and an air pump. Several automatic sealed devices are uniformly distributed on a circle edge of the center disc. A lower end is connected with a collector. A bottom of the collector is communicated with an air hole in an upper sealed plate body through an air tube. The periphery bottom of the upper sealed plate body is connected with a support. A lower part of the support is connected with a dial position plate. Shifting forks are distributed on a circle of the dial position plate. Pins are arranged on the rack and are matched with the shifting forks. The lower part of the upper sealed plate body is provided with a lower sealed plate body. The air holes, which are matched in the positions, are arranged on a contact surface between the upper sealed plate body and the lower sealed plate body. A gas seal structure is arranged between the upper sealed plate body and the lower sealed plate body. The lower sealed plate body is fixedly installed on a support platform. The air holes of the lower sealed plate body are communicated with a roughing pump, a molecular pump or a diffusion pump, and an argon gas pipe. The molecular pump or the diffusion pump is connected with a fine drawing pump through a pipeline. The machine is high efficient and energy saving. A production speed is fast. The machine has an active role in development of the electrodeless lamp.

AI Technical Summary

Problems solved by technology

[0002] The long row car used in the existing electrodeless lamp exhaust process was developed due to low efficiency, high energy consumption and poor consistency. The long row car is to connect several or more than a dozen electrodeless bulbs to be exhausted in a row. On the pipe, there is a heating oven to cover the heating and degassing. The system uses a suction pipe to connect a group of fine pumps (a vacuum pump and a diffusion pump), a rough pump, and an inflation system.

[0003] When leak detection and air extraction, a few dozen bulbs are exhausted with a rough pump. The internal volume of the pumped device is very large, and the miscellaneous air cannot be discharged in time. At this time, the oven is heated to remove the air. Absorbed and adsorbed impurity gases are released together, and many bulbs are pumped directly from a pumping hole and a rough pump, which is difficult to discharge in time, and the impurity gases released from the heated inner surface will make the internal components and inner parts of the bulbs at high temperature. Surface Coating Contamination Affects Luminous Efficiency of Phosphors

[0004] A group of fine pumping pumps vacuumize more than a dozen light bulbs. To achieve a higher vacuum degree, the pumping time will inevitably be lengthened and affect production efficiency, and it is difficult to achieve the ideal vacuum degree due to the large volume of the pumped device.

[0005] The electric power of each long-row car heating oven is nearly 25kw, and the exhaust of each car takes 40-50 minutes to complete, so the long heating time and long pumping time result in high energy consumption

It takes 40-50 minutes per car to produce more than a dozen bulbs, which is low in production efficiency

[0006] The number of bulbs installed in each car is far or near from the air inlet and the air inlet, and the airflow is early or late. Each shift has several cars and each person operates one, resulting in differences between each car, each set, and each person, thus affecting the bulbs. Consistency, increasing the difficulty of matching the whole lamp power supply
