Problems solved by technology
[0004] 1) The currently used o-ring side pressure heat wrapping process has problems such as o-ring being pressed, fluff, twisting, etc., which may lead to poor airtightness of the lens, and lacks 100% effective in the production process means of early detection;
[0005] 2) For lenses with poor airtightness, since they have been heat-pressed, there is no room for rework, especially for lens barrels with poor airtightness that have been heat-pressed, they need to be 100% scrapped;
[0006] 3) According to the production demand, the production line needs to be equipped with 2 hot-pressing hemming machines and 1 air-tight equipment. Each machine needs 1 person to operate, and the personnel and equipment are not streamlined enough.

The invention discloses an air tightness detection and hot-pressing edge covering device which comprises an air tightness detection assembly and a hot-pressing edge covering assembly. The air tightness detection assembly is provided with a cavity for containing a workpiece to be detected, and one side of the cavity is open; on the open side of the cavity, the inner wall of the cavity makes sealingcontact with the workpiece to be detected; and the workpiece to be detected is pressed by a pre-pressing rod to prevent testing gas from entering the cavity and then moving the workpiece to be detected. The hot-pressing edge covering assembly comprises an edge covering heat with a through hole, and the through hole allows the pre-pressing rod to penetrate through.
Description
technical field [0001] The present application relates to the field of automatic production and testing of optical lenses, and more specifically, the present application relates to an integrated device for air tightness testing and hot-pressing hemming and a processing method using the device. Background technique [0002] The air tightness test is to detect the sealing performance of the lens, and it is a necessary test item for the lens of the model with waterproof requirements. Hot pressing is the main process used to fix the lens, and it is an important link in the lens production process. [0003] In the existing production process, the lens is usually hot-pressed and edged first, and then the airtightness test is performed afterwards. However, the existing technology has the following defects: [0004] 1) The currently used o-ring side pressure heat wrapping process has problems such as o-ring being pressed, fluff, twisting, etc., which may lead to poor airtightness ...
