Abstract

The invention relates to a camera airtightness testing device, which belongs to the technical field of airtightness detection equipment, and comprises a bracket, a testing mechanism, a linear guide rail and a circular pen-shaped cylinder, the testing mechanism comprises a pressing cylinder, an upper cavity and a lower cavity; the pressing cylinder is mounted on the bracket; a piston rod of the pressing air cylinder penetrates through the top of the support, then the end of the piston rod is connected with the top of the upper cavity, a vent hole for detection is formed in the upper cavity, a set of linear guide rails are arranged under the upper cavity, a lower cavity capable of being buckled with the upper cavity is installed on the linear guide rails, and the lower cavity is fixedly connected with the end of the piston rod of the round pen-shaped air cylinder. According to the invention, the upper cavity and the lower cavity of the test mechanism are separately arranged, and the lower cavity can move, so that the camera is moved from the previous station to the detection station, and the work of manually carrying the camera is avoided; Meanwhile, the camera is detected after theupper cavity and the lower cavity are buckled in a closed manner, so that the test precision is high.

Description

technical field [0001] The invention belongs to the technical field of air tightness testing equipment, and in particular relates to a camera air tightness testing device. Background technique [0002] When the camera is assembled, the shell and the end cover are usually welded to each other by welding technology, and the sealing performance of the welding seam is directly related to the sealing performance of the camera as a whole. [0003] Now it is necessary to make a camera assembly line to realize automatic assembly and testing of multiple stations, one of which is to conduct air tightness testing. However, the currently used camera air tightness testing device cannot realize automatic detection, and it is necessary to manually put the camera into the detection device for detection. [0004] In order to eliminate manual operations and improve the consistency rate of test conditions, the present application provides a device capable of automatically testing camera airti...
