Lens seat testing device and method

Abstract

The invention relates to a lens base testing device and a testing method. The lens base testing device comprises: a fixing and retaining unit used for fixing and retaining the lens base; a testing unit used for testing the resistance of a coating for preventing electromagnetic interference on the surface of the lens base fixed and retained by the fixing and retaining unit; at least one clamping unit used for clamping and transmitting the lens base; and a control unit used for controlling the distance between the testing unit and the lens base to keep a certain value when the testing unit teststhe lens base, simultaneously receiving and processing the test value of the testing unit to detect whether the lens base is quality goods and controlling at least one clamping unit to clamp and movethe lens base. Moreover, the invention also relates to the lens base testing method adopting the lens base testing device. By arranging the control unit to control the distance between the testing unit and the lens base in the process of testing, the lens base testing device and the testing method not only realize the automation of the lens base testing, but also achieve better testing quality.

Description

Technical field [0001] The invention relates to a testing device and a testing method for testing the surface resistance of a lens base of a lens module. Background technique [0002] With the development of camera technology, lens modules have been widely used in camera devices for various purposes. The combination of lens modules with various portable electronic devices such as mobile phones and computers has been favored by many consumers. [0003] However, with the development of portable electronic devices in the direction of diversified functions, their components have become more and more complex, and most of the components need to be energized to work, which causes the portable electronic devices to be easily affected by electromagnetic interference normal work. [0004] Lens modules are generally used as components of imaging devices and are widely used in portable electronic devices. They generally include lenses, lens holders, filters, and spacers for separating lenses an...

Problems solved by technology

The usual practice is to directly test the resistance value of the coating by holding the probe of the electrometer by hand. However, because the tip of the probe is very sharp, it is easy to scratch the coating and cause test errors. Therefore, the probe must follow the The surface of the coating is kept at a certain distance to ensure the quality of the test. It is understandable that it will be difficult to meet the above test requirements by manual operation.
