Automatic glue dispensing device for imaging lens

Abstract

The invention provides an automatic glue dispensing device for an imaging lens, and the automatic glue dispensing device is characterized by comprising a workpiece locating device, a workpiece detecting device, a glue dispensing device, a glue curing device and a control system which are all arranged on a working platform, wherein as the detecting equipments with various functions is arranged on the one working platform on which the workpiece locating device, the workpiece detecting device, the glue dispensing device, the glue curing device and the control system for the imaging lens are arranged, thereby reducing more and complex steps for the traditional lens assembling process, increasing the production efficiency and improving the quality of products. In addition, the automatic glue dispensing device for the imaging lens has the advantages of low disposable equipment cost investment, high degree of automation, simplicity and convenience for operation in production, labor cost reduction, production efficiency increment, reduction of interference from personal factors and improvement on product quality.

Description

technical field [0001] The invention relates to imaging lens processing equipment, in particular to a detection, adjustment, glue dispensing and curing device suitable for micro-projection imaging lenses. [0002] Assembly machine. Background technique [0003] At present, the main structure of the miniature projection imaging lens includes a lens barrel, several lenses or lens groups, a pressure ring, and a spacer. When the lens is loaded into the lens barrel, the optical axis must be parallel to the axis of the lens barrel, and the optical axes of all lenses must coincide. The first lens at the end face of the lens barrel is pressed into the lens barrel with a pressure ring through threads or glue. The lenses in the middle are some in direct contact and some are separated by spacers. On the connecting surface between the edge of the lens and the spacer and the lens barrel, inject UV glue and cure it to fix the lens. [0004] In the production process of micro-projectio...

Problems solved by technology

In the process of sending the glue to the UV curing machine after dispensing, it must be ensured that the relative position of the lens and the lens barrel cannot be changed, otherwise it may cause defective products

[0005] At present, the industry generally adopts a manual method to assemble this kind of miniature projection imaging lens, which requires very high processing precision of the lens barrel and lens, and very high technical requirements for assembly. Such a manual production method is difficult to assemble and low in efficiency. The quality of the product is not high, and the consistency of the product is difficult to guarantee, which increases the manufacturing cost
