Problems solved by technology

[0004] When this dispensing equipment is in use, its starting position is still judged by the human eye, so human errors will occur, resulting in the inability to accurately locate the dispensing position
In addition, due to the difference in the dispensing position after each adjustment, the dispensing amount of the dispensing device is not easy to control, and it is easy to cause glue overflow or insufficient glue, thereby affecting the imaging quality of the entire lens; on the other hand, it is easy to The amount of glue dispensing is uneven, resulting in stress at the bonding point between the lens, the lens barrel and the spacer ring. Under long-term use, the lens barrel and the spacer ring are likely to fall off and the camera lens module cannot be used.

Embodiment Construction

[0012] Please refer to FIG. 1 , the dispensing device 10 of this embodiment has a needle 11 , a syringe 12 , a range finder 14 and a three-axis controller 30 . The needle 11 is connected with the syringe 12 , and the range finder 14 is arranged on the syringe 12 and closely combined with the outer wall of the syringe 12 . The syringe 12 is fixed on the three-axis controller 30 .

[0013] The needle 11 can be in the shape of a hollow cylinder, and a flow channel 111 for flowing viscose is arranged therein, and the end of the flow channel 111 away from the syringe 12 is used for flowing out the viscose.

[0014] The syringe 12 can be in the shape of a hollow cylinder, and an inner chamber 121 for pre-storing glue is arranged in it, and the inner chamber 121 communicates with the flow channel 111 .

[0015] The three-axis controller 30 can control the glue dispensing device 10 to move freely in the directions of X, Y, and Z axes, so as to adjust the needle head 11 to a predeterm...

Abstract

The present invention provides glue applying device and method. The glue applying device includes one injector with one glue flow channel, one cylinder connected to the injector and with one glue holding cavity communicated to the glue flow channel in the injector, and one triaxial controller for the cylinder to be fixed on. The glue applying device has also one range finder connected electrically to the triaxial controller. The range finder detects the distance between the injector and the glue applying site and transfers the detected distance to the triaxial controller, so that the triaxial controller can regulate the injector to proper location.

Description

technical field [0001] The present invention relates to a glue dispensing device and a glue dispensing method, in particular to a glue dispensing device and a glue dispensing method suitable for camera lens assembly. Background technique [0002] With the continuous development of science and 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 high photographic performance. The digital camera lens module assembly method is a major factor that determines the photographic performance. In the digital camera lens module assembly process, a dispensing device is used to glue the camera components. Therefore, improving the dispensing device will help improve its performance. as...
