Problems solved by technology

However, when this method is used for automatic dispensing, the dispensing needle needs to be positioned multiple times, which greatly wastes time
In addition, the dispensing method is likely to lead to inaccurate alignment of the dispensing needle, making dispensing invalid and affecting the quality of dispensing
Because one of the reasons for the failure of the lens module during use is that the filter in the lens module falls off, which will directly affect the quality of the lens module
During the assembly process of the lens module, especially when fixing the optical filter on the spacer ring, if there are dispensing quality problems such as uneven dispensing and insufficient dispensing amount, it will seriously affect the distance between the filter and the spacer ring. Adhesion
Due to the weak adhesion between the optical filter and the spacer ring, the probability of lens module failure due to the detachment of the optical filter during use will be greatly increased

Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] Please refer to FIG. 1 and FIG. 2 , the dispenser 100 for lens module assembly provided by the first embodiment of the present invention includes a base 10 having a groove 20 and a channel 30 inside. , the groove 20 is used for accommodating the component 40 to be dispensed.

[0013] The shape of the groove 20 can be made according to the shape of the component 40 to be glued. In this embodiment, the groove 20 is a cylindrical groove. The groove 20 has a groove bottom 21 , the groove bottom 21 includes a non-glue area 211 and a glue area 212 , and the glue area 212 is provided with a plurality of glue outlets 2121 . In this embodiment, the non-glue-discharging area 211 is located at the central area of ​​the groove bottom 21 , and the glue-discharging area 212 is located at the edge area of ​​the groove bottom 21 . Preferably, the glue outlets 2121 a...

Abstract

A glue-setter used in assembly of lens module is prepared for setting a groove being used to contain element to be glue-set and a channel on base, arranging glue non-outgoing region and glue outgoing region on bottom of said groove, setting multiple glue outgoing-opening at glue outgoing region, using said channel to store glue and connecting said channel to glue outgoing-opening.

Description

technical field [0001] The invention relates to a glue dispenser, in particular to a glue dispenser used for lens module assembly. Background technique [0002] With the continuous development of technology, portable electronic devices, such as mobile phones, are widely used and tend to be light, beautiful and multi-functional. The camera function is an additional function of the popular mobile phones in recent years. A digital camera module used in a mobile phone must not only meet the requirements of thinness, lightness and compactness, but also have better photographic performance. And digital camera lens module assembly device and method are a main factor of determining photographic performance. [0003] During the assembly process of the lens module, the optical filter and the spacer ring are generally fixed by a dispensing process. The specific method is to use a small glue dispenser to apply glue drop by drop on the junction of the optical filter and the spacer ring...
