Problems solved by technology

However, if the lamination parameters of the lamination device are changed due to various reasons during the lamination process, since it cannot be known and adjusted in time, more unqualified lenses will be produced, and this unqualified can only be known in subsequent tests
Therefore, the production yield of the lens will be extremely low, and many useless operations will be performed, causing great waste and increasing production costs

Abstract

An assembling and testing apparatus for the lens which is used to assemble and test the lens is disclosed. The lens includes a drawtube and a lens array. The apparatus contains a stitching device, a testing device and a rotating disc. The stitching device presses the lens array in the drawtube, and the testing device tests the lens. The drawtube of the lens is mounted on the rotating disc which can rotate relatively to the stitching device and the testing device to make the drawtube over against the stitching device and the testing device. Said assembling and testing apparatus for the lens could assemble and test the lens at the same time, monitor and adjust the parameters of the machine being assembled at any moment, reduce or eliminate useless operation, improve the production efficiency, ensure the excellent ratio of the assembly, and two steps of assembling and testing can be finished just by one action to improve the production efficiency further.

Description

【Technical field】 [0001] The invention relates to a lens assembly and testing device. 【Background technique】 [0002] With the development of multimedia technology, digital imaging products such as digital cameras and digital video cameras have been widely used by people and have a large market demand. In addition, in recent years, mobile phones are also rapidly developing in the direction of high performance and multi-function, and mobile multimedia devices that combine digital cameras with mobile phones, PDAs and other portable electronic devices are also widely used, so the demand for digital camera lenses is also increasing. bigger. However, due to factors such as the manufacture of lens components and the yield rate of lens assembly, the price of the lens is still relatively high, thus causing the high price of digital cameras and digital video cameras to a certain extent. [0003] The general method of camera lens assembly is to press the lens, spacer ring, aperture ...
