Problems solved by technology

[0004] However, in the dispensing process, there will be some offset between the glue coating position and the position where glue needs to be coated due to lens module assembly errors, machine base errors, rotation coaxiality errors, dispensing needle movement errors, etc. This will lead to uneven dispensing, which will affect the assembly effect of the lens module

Abstract

The present invention provides a method for measuring the distribution of the glue-pointing volume, and includes the following procedures: A. providing a glue-pointing device and a component to be glue-pointed; B. using the glue-pointing device to point glue on the component to be glue-pointed; C. determining a datum mark on the axes of a lens module; D. controlling the pinhead to move to the first edge point of gluewater, and recording the coordinate values of the three axes; E. controlling the pinpoint to move from the first edge point to the second edge point, and recording the coordinate values of the three axes of the second edge point, ensuring that the first edge point, the second edge point, and the axes of the lens module are in a same plane; F. according to the coordinate values of the three axes of the first edge point and the second edge point, calculating the distribution volume of gluewater on the parallel direction to the axes and the distribution volume of gluewater on the perpendicular direction to the axes; G. rotating the glue-pointed component, repeating the procedures of the D-F, obtaining a plurality of distribution volume of gluewater on the parallel direction to the axes and on the perpendicular direction to the axes, and then evaluating the distribution state of gluewater. The method uses the prior glue-pointing device to measure the distribution of the glue-pointing volume, and is simpler and rapider.

Description

technical field [0001] The invention relates to the glue dispensing technology in the lens module assembly process, in particular to a method for measuring the distribution of glue dispensing. Background technique [0002] A lens module applied to a camera or an optical instrument usually includes a lens mount, a lens barrel, a lens group, a spacer ring and a filter, wherein the lens group, the spacer ring and the filter are sequentially fixed in the lens barrel along the optical axis , the spacer ring and the filter are tightly fixed together. [0003] During the assembly process of the lens module, the optical filter and the spacer ring are generally fixed through a dispensing process. The glue dispensing process is completed by the glue dispensing device and the rotating platform, which can drive the lens module to rotate. The dispensing device includes a controller and a dispensing syringe with a dispensing needle at one end, and the controller can control the dispensi...
