Description
Technical Field
The utility model relates to a feeding device of equipment for completing exhaust packaging of a pressure bag in the same furnace chamber, and belongs to the technical field of vacuum packaging.
Background
The film vacuum gauge is an instrument for measuring vacuum degree, and its principle is to measure vacuum degree by utilizing the motion rule of gas molecules in vacuum, and it has a key component-pressure bag, and the exterior of the pressure bag has an exhaust tail pipe for evacuating, an external connection pipe for external connection of detection object and two positive and negative electrode wire connectors for connecting instrument.
According to the measurement principle, the film vacuum gauge can be divided into a plurality of types, and the measurement range of the vacuum degree is 1.33×10 5—1.33x10-2 Pa.
The film vacuum gauge has a very wide application range and can be applied to various fields of aerospace, electronics, chemical industry, medical treatment and the like. For example, in the electronics field, thin film vacuum gauges can be used to test vacuum tubes, semiconductor devices, to ensure their normal use and lifetime.
The film vacuum gauge pressure package is a main component of the whole film vacuum gauge, and how to vacuumize and package the pressure package more standard, simpler, more economical and more efficient is always a problem discussed in the field. There are two conventional solutions:
firstly, placing the sample in a high-temperature high-vacuum environment, and sealing by adopting a high-temperature eutectic welding method, a brazing method or a glass sintering method and the like. However, the vacuum welding void ratio is high, so that the sealing performance of a sealing area is affected, and the maintenance of the vacuum degree in the reference cavity can be affected.
And secondly, adopting oxygen-free copper as a sealing material, and performing clamping by using a clamping device under the condition of continuous vacuumizing. However, the degassing step before sealing is insufficient, and the vacuum degree in the reference cavity is difficult to improve.
In order to solve the above-mentioned problems, various solutions are proposed in the prior art, and the following two patent documents disclose more typical solutions:
The application number is 202211376858.9, the name is a sealing and arranging table for an active electric vacuum device and an integrated twice sealing and arranging method, and the sealing and arranging table disclosed in the document comprises an outer vacuum system, an inner vacuum system, a control system, a heating system, a high-voltage power supply and a mechanical lifting system; the external vacuum system is used for providing a high vacuum environment in an external vacuum cavity in the furnace body and providing a vacuum working environment for the outside of the active electric vacuum device; the inner vacuum system is used for exhausting the active electric vacuum device in the furnace body and providing an ultrahigh vacuum environment for the active electric vacuum device; the heating system is used for electrifying the heating body and heating an active electric vacuum device in the furnace body; and the high-voltage power supply is used for driving the active electric vacuum device to work and generating X rays. The invention realizes the high-quality integrated ultrahigh vacuum sealing and discharging of the metal ceramic X-ray tube on the premise of improving the efficiency, saving energy and reducing emission, and improves the production efficiency and the production yield. The general manner of packaging is disclosed in the specification, and the word "pinch-off" is disclosed in fig. 7.
The application number 202211282013.3 is a reference chamber forming device and a reference chamber forming method for a film vacuum gauge, and the reference chamber forming device for the film vacuum gauge disclosed in the document comprises: the degassing module comprises a baking chamber and a first vacuum pump set for vacuumizing the baking chamber; the clamping module comprises a main cavity, a clamping mechanism arranged in the main cavity and a second vacuum pump set for vacuumizing the main cavity; the main chamber is arranged at the downstream of the baking chamber and is communicated with the baking chamber through a first valve capable of controlling opening and closing; the conveying module is used for enabling the sample to be processed to be conveyed in a sealing mode between the degassing module and the clamping module; the gas backfill module is provided with a plurality of backfill branches capable of controlling on-off, is connected with the degassing module and the clamping module and is used for backfilling gas into the degassing module and the clamping module. The problems of high vacuum welding temperature and large void ratio are avoided, and the sealing performance of a sealing area is ensured; and before sealing, baking and degassing are adopted to accelerate the outgassing of the sample material to be processed, so that the vacuum degree in the reference chamber is improved.
The two technical schemes relate to the vacuum pumping and packaging operation of the vacuum part of the film vacuum gauge in the vacuum environment of the vacuum chamber, the idea of the invention is only focused on how to reach the quality standard of the product, and a specific creative technical scheme is not provided for how to solve the problems of vacuum pumping and packaging of the vacuum part by means of simpler, more economical and more efficient measures.

A conveying mechanism for accurately clamping and pushing the workpiece is also required to be arranged between the two vacuum chambers.
2. The process is complex. After one chamber completes high-temperature vacuumizing on the pressure bag, the pressure bag needs to be pushed to the other chamber for tail cutting and packaging.
