Problems solved by technology

The main purpose of the full inspection is to ensure that the quality of each shipped product is qualified. However, in the existing motor testing device, due to the manual assembly of the motor and the lens to be tested, the test efficiency is low, the controllability is poor, and the production cost is high. Assembly It is easy to introduce foreign matter into the motor during the process, which will affect the later use of the product
In addition, manual assembly may cause secondary damage to the motor, resulting in inconsistent product quality

Abstract

The invention discloses a VCM (Voice Coil Motor) testing mechanism, a testing system comprising the VCM testing mechanism and a testing method. The VCM testing mechanism comprises a testing fixture for mounting a motor, a lens capable of self positioning, and a lens taking and placing assembly of the motor, wherein the lens taking and placing assembly is used for mounting the lens into or taking the lens out of the testing fixture and at least comprises a pressing plate which can be used for selectively clamping or loosening the lens, and a positioning assembly for resetting the lens. By arranging the positioning assembly, the position consistency of the lens after the lens is mounted into or taken out each time can be guaranteed; compared with the traditional technology, the scheme provided by the invention has the advantages that the full automation is realized, and the batch testing work becomes possible. The testing system comprises the VCM testing mechanism and a material taking mechanism for mounting the lens into or taking the motor out of the testing fixture; the material taking mechanism comprises a motor nozzle; a positioning structure for positioning the motor is arranged on the motor nozzle. The positioning structure is arranged for accurately positioning the position of the motor.

Description

technical field [0001] The invention relates to the technical field of VCM testing, in particular to a VCM motor testing mechanism and a testing system including it, and also relates to a testing method for automatically testing a VCM by using the testing system. Background technique [0002] VCM (Voice Coil Motor Chinese: voice coil motor) is named for its structure similar to the voice coil of the speaker. It is called the voice coil linear motor. The structure is divided into two parts: the voice coil and the magnet. When passing through the magnetic field, a force perpendicular to the magnetic field line will be generated. The magnitude of this force depends on the length of the conductor passing through the magnetic field, the strength of the magnetic field and the current. The voice coil motor converts the actual current into linear thrust or torque. Their The magnitude is proportional to the magnitude of the actual passing current. [0003] The camera modules of high...
