Air tightness detection device

Abstract

The invention belongs to the technical field of detection of assembling air tightness of a plastic electronic product and discloses an air tightness detection device. The air tightness detection device comprises a sealing device, a product clamping fixing and testing device and a product testing and identifying device. The air tightness detection device has the following advantages that 1, the sealing device, the product clamping fixing and testing device and the product testing and identifying device are reasonably integrated and can be widely embedded into various types of assembling testing equipment and are seamlessly joined with all assembling measuring procedures, so that the field area of the equipment is reduced, and the field cost is effectively reduced; 2, continuous and batch product detection can be rapidly carried out, and the detection period is shortened; the labor cost is reduced, and the product detection efficiency is effectively improved; 3, the production detection can be accurately carried out and the quality of outgoing products is improved, so as to guarantee the market competitiveness of enterprise products. To sum up, the difficulty in a detection aspect of assembly line products of existing enterprises is solved, the requirements on rapid and accurate detection of the products are realized, and the investment of enterprise production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of plastic electronic product assembly air tightness detection, in particular to an air tightness detection device for irregular products. Background technique [0002] As we all know, the products produced by enterprises need to be tested for air tightness, and the airtightness of their products directly affects the product qualification rate and use safety. However, in view of the current production line production requirements of enterprises, the detection device must achieve fast and accurate Conduct product testing. [0003] At present, the commonly used methods for air tightness testing often use the bubble method, smear method, chemical gas tracer leak detection method and differential pressure method. Among them, the traditional leak detection methods mostly use the bubble method and the smear method. The bubble method is to immerse the workpiece in water, fill it with compressed air, and then colle...

Problems solved by technology

Among them, the traditional leak detection methods mostly use the bubble method and the smear method. The bubble method is to immerse the workpiece in water, fill it with compressed air, and then collect the air bubbles leaking out of it within a certain period of time to measure the leakage; the smear method is internal The surface of the workpiece filled with a certain air pressure is smeared with soapy water and other liquids that are prone to bubbles, and the bubbles are observed to detect the size of the leakage. The above two methods are simple to operate and can directly observe the location and situation of the leakage, but Since the location and several leaks of the workpiece are not known in advance, on the one hand, it is difficult to collect all the air bubbles, which affects the accuracy of the measurement; Difficult to observe

After the test, the workpiece needs to be cleaned and dried, and automatic and quantitative leak detection cannot be realized. Therefore, these two methods are unable to meet the production requirements of high precision and high efficiency.
