Usage tester for electronic tube of electronic component

Abstract

The invention discloses a use tester for an electronic tube of an electronic component, and relates to the technical field of air tightness detection. The device comprises a base, a water tank is installed on the upper surface of the base, connecting plates are installed on the two sides of the water tank, first electric push rods are fixedly installed on the upper surfaces of the connecting plates, supporting plates are fixedly installed at the upper ends of the first electric push rods, supports are fixedly connected to the front and rear portions of the supporting plates, and a detection plate is fixedly connected between the supports. A fixing frame is installed in the middle of the upper surface of the detection plate, an upper clamping plate is movably connected below the fixing frame, a lower clamping plate is fixedly installed below the upper clamping plate, and a square air pipe is arranged on one side of the lower clamping plate. An electronic tube is placed between the upper clamping plate and the lower clamping plate, one end of the electronic tube is inflated, the first electric push rod drives the detection plate to move downwards into the water tank, whether bubbles are generated on the surface or not is observed, the welding airtightness of the electronic tube is detected, multiple electronic tubes can be detected at the same time, and the detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of air tightness detection, in particular to a use tester for electron tubes of electronic components. Background technique [0002] The electron tube is one of the earliest electrical signal amplification devices. The cathode electron emission part, the control grid, the acceleration grid, and the anode (screen electrode) leads that are enclosed in a container (usually a glass tube) are welded on the tube base. The electric field is used to inject electronic modulation signals to the control grid in vacuum, and the signal data of different parameters after signal amplification or feedback oscillation are obtained at the anode. [0003] At present, the electronic tube is usually a metal tube. During the production process, one end needs to be welded and sealed. The verification of the welding effect requires an air tightness test. Generally, the worker inflates one end of the electronic tube and then soaks ...

Problems solved by technology

[0003] At present, the electronic tube is usually a metal tube. During the production process, one end needs to be welded and sealed. The verification of the welding effect requires an air tightness test. Generally, the worker inflates one end of the electronic tube and then soaks it in water to check the air tightness of the electronic tube. For detection, the detection efficiency is low, and it does not have security
