Abstract

A rear cover air tightness detection device is characterized in that the device comprises a cover plate, an air inlet pipe and a cable jack shell; connecting holes are formed in the circumference of the cover plate and used for being connected with positioning holes in a rear cover; a center hole is formed in the cover plate, and one end of the air inlet pipe is connected with the center hole of the cover plate; and the cable jack shell is used for sealing a cable hole of the rear cover. When the rear cover air tightness detection device provided by the invention is used for detecting the air tightness of the rear cover, the device only needs to be mounted on the rear cover, then the whole device sinks into water, compressed air is introduced, and the air pressure of the compressed air is adjusted to a set value; whether bubbles emerge from a rear cover welding seam or not is observed, and the air leakage condition within 10 minutes is measured; and if the welding seam of the rear cover does not have bubbles or the air leakage in 10 minutes does not exceed 0.1 atmospheric pressure, the air tightness of the rear cover is qualified.

Description

technical field [0001] The invention relates to the technical field of airtightness detection, in particular to an airtightness detection device for a rear cover and a method for using the same. Background technique [0002] Such as figure 1 The rear cover in the structure shown is an important part of a certain type of radio controller. It is used to place the radio controller after being combined with the front cover, and is filled with nitrogen. The main reason is that the internal radio controller products play a protective role, and shock resistance must be required. Waterproof and airtight. [0003] Therefore, each component of the back cover is welded by argon arc welding. In order to ensure the sealing performance of the back cover, a 100% airtight test is performed on the weld seam after welding. At present, the commonly used air tightness detection method is to seal the mouth of the back cover and then rush into the compressed air, sink into the water, and Obse...
