Seal test device for metal housing of photoelectronic device

Abstract

The invention discloses a seal test device for a metal housing of a photoelectronic device. The seal test device comprises a base, a seal detection box, a controller, a placement frame, a metal housing body, an air pressure sensor and a vacuum pump; the seal detection box is mounted at the upper part of the base; a controller is mounted on the outer wall of the seal detection box; the placement frame is placed inside the seal detection box; the metal housing body is placed on the placement frame; the air pressure sensor is arranged inside the metal housing body; a box cover is mounted at the upper part of the seal detection box; an exhaust tube is mounted on the seal detection box; the vacuum pump is mounted on the exhaust tube; an air inlet pipe is mounted on the box wall of the seal detection box; and an electromagnetic valve is mounted on the air inlet pipe. By the arranged base, seal detection box, controller, placement frame, metal housing body, air pressure sensor and vacuum pump, the seal test device disclosed by the invention solves problems of low detection speed and low efficiency when the metal housings of the photoelectronic devices are manually detected one by one.

Description

technical field [0001] The invention relates to the technical field of sealing testing, in particular to a sealing testing device for metal casings of optoelectronic devices. Background technique [0002] Optoelectronic devices mainly include: photoconductive devices that use the photosensitive properties of semiconductors, photocells and semiconductor light-emitting devices that use semiconductor photovoltaic effects to work. Semiconductor optoelectronic devices such as light pipes, photocells, photodiodes, phototransistors, etc.; semiconductor thermoelectric devices such as thermistors, thermoelectric generators, and thermoelectric coolers. Among them, when the optoelectronic device is used, a metal casing will be installed on the outside of the carrier gas. Before the metal casing is used, it needs to be tested to detect the sealing performance of the metal casing. [0003] However, the prior art has the following disadvantages: the metal shells are manually detected one...
