Abstract

The invention relates to the technical field of voice coil motor production equipment, in particular to a levelness and height measuring instrument for voice coil motor lens module production. A light source cavity, a glass base, a vertical tube and a lens holder are vertically connected in turn. A cross line calibration target is installed between the light source cavity and the glass base. A CCD connector is horizontally arranged at the side of the glass base. A glass plate is installed in the glass base. The glass plate is disposed right below the cross line calibration target, and tilts towards the CCD connector. The included angle between the glass plate and the horizontal line is 45 degrees. An altimeter is installed in the vertical tube. A lens is horizontally installed in the lens holder. The lens has a through hole in the middle. The altimeter is installed vertically, and passes through the through hole. The lower end of the lens holder is connected with a contact block fixing base. A contact block is placed in the contact block fixing base. The contact block has a protruding part at the bottom which protrudes out of the contact block fixing base. The bottom end of the altimeter is in contact with the top surface of the contact block. An object to be measured is in contact with the contact block. The levelness and height can be judged quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of voice coil motor production equipment, in particular to a level measuring instrument for production of voice coil motor lens modules. Background technique [0002] In the production of voice coil motors, the relative level of the lens and the sensor, and the relative height (focal length) of the lens and the sensor affect the imaging quality of the product. At present, there are few companies that can accurately measure the level and height of the lens when assembling. The measuring instrument, and the deviation of the level and height of the lens assembly may be very, very small, so that a large number of substandard products will be produced due to undetectable, affecting product quality. [0003] Therefore, based on the above defects in the production of the existing voice coil motor lens module, it is necessary to improve the production of the existing voice coil motor lens module. Contents of the i...
