Problems solved by technology

However, it uses detection sensors to detect air tightness. The existing sensors still have the problem of low precision in air tightness detection, and there are still large errors, which cannot meet the requirements of the application.
At the same time, during the detection process of the device, the switching cycle between the execution units is long, and the accuracy of the movement of the lower mold cannot be adjusted, which is easy to damage the product
[0004] Therefore, the development of a device for detecting airtightness between glass and metal parts in the lens can solve the problems of low detection accuracy and low efficiency of existing airtightness detection equipment, so as to further improve detection efficiency, Obviously has practical practical significance

Embodiment 1

[0067] Such as Figure 1-Figure 7 As shown, a kind of airtightness testing equipment is used to detect the airtightness between the glass in the lens 11 and the metal parts, including a chassis 1, a product feeding device 2, a material shifting device 3 and a detection device 4, said The product feeding device 2, the material shifting device 3 and the detection device 4 are all arranged above the cabinet 1;

[0068] The detection device includes several second product carriers 5, several pressing devices 6 and several leak testers 7, and the number of the pressing devices is the same as that of the second product carriers, and the pressing devices arranged above the second product carrier and corresponding to the second product carrier;

[0069] Each of the second product carriers 5 includes a positioning device 51 and several product positioning devices 52 arranged on the positioning device 51. Each of the product positioning devices is a hollow structure, and each of the pr...

Embodiment 2

[0108] This embodiment is carried out on the basis of the first embodiment above, and the similarities with the above embodiment will not be repeated.

[0109] In this embodiment, a cavity is provided inside the compact.

[0110] Further, the third ventilation pipeline is provided with a three-way leakage hole, and the third ventilation pipeline connected to the leak tester is divided into two branches after passing through the three-way leakage hole, and one branch is connected to the briquette. communicate with the second air duct on the top, and another branch communicate with the cavity inside the briquetting block. Before the test is carried out, it is necessary to close the branch in the tee leak hole that communicates with the cavity in the briquetting block, and then test; when the test data of the lens is abnormal, open the branch in the tee leak hole that is connected to the cavity The branch circuit communicating with the cavity inside the briquetting block is closed...

Abstract

The invention discloses an airtightness detection device and a detection method thereof, which are used for detecting the airtightness between glass and metal parts in a lens, including a chassis, a product feeding device, a material moving device and a detection device. The detection device includes several second product carriers, several pressing devices and several leak testers, and the pressing device is arranged above the second product carrier and connected to the second product carrier one by one. Correspondingly; the present invention forms a test cavity by using the cooperation between the second product carrier and the pressing device, inputs air into the lens through the air input device, and detects the amount of air flowing from the lens to the test cavity through a leak tester And the leak rate of the lens is calculated by the leak rate formula, and the leak tester is calibrated by the standard test block before the leak tester test, to avoid the detection error caused by the leak tester itself, the detection error is small, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of non-standard automation equipment, in particular to an air tightness detection device and a detection method thereof. Background technique [0002] At present, there are metal sheets and glass lenses on the periphery of the mobile phone camera. After the metal and glass lenses are assembled, the firmness and airtightness of the assembled products need to be tested. The traditional detection method is to detect one by one by manual hand-held detection instruments, and the detection efficiency is low; and the product is small in size, and the hand-held detection instrument can directly detect whether the air leakage can not identify the small air leakage, so there are large detection errors, In the case of poor precision, therefore, hand-held testing instruments are not suitable for lenses that require high-precision testing. In addition, when there are many products, the labor intensity of the staff is hi...
