Problems solved by technology

However, in the process of dispensing, the lens barrel 30a often rotates away from the axis. Since the dispensing syringe 12a is fixedly installed on the holding device 11a, the dispensing needle 13a cannot be retracted, and the lens barrel 30a and the When the above-mentioned dispensing needle 13a is touched hard, the phenomenon of hitting the needle will occur, resulting in a production stop and a decrease in production efficiency

[0011] Please also see figure 2 and image 3 The dispensing device 100 of this embodiment includes a base 10, a dispensing syringe barrel 20, at least one holding collar 30 sleeved on the dispensing syringe barrel 20 and fixed on the base 10, at least An action portion 21 and at least one elastic element 40 are provided on the outer wall of the dispensing syringe 20 . One end of the dispensing syringe barrel 20 is provided with a dispensing needle 22 . The elastic element 40 is installed between the action portion 21 and a retaining collar 30 adjacent to the action portion 21 . Each elastic element 40 is used for exerting an elastic action on a corresponding action portion 21 so that the dispensing syringe barrel 20 is in an elastic equilibrium state.

[0012] The dispensing device 100 of this embodiment includes two retaining collars 30 , two elastic elements 40 and one action portion 21 . The two elastic elements 40 are located between the two retaining collars 30 and a...

[0022] see Figure 4 The difference between the dispensing device 200 of the second embodiment of the present invention and the dispensing device 100 of the first embodiment lies in the difference in the number and arrangement of the holding collar, the elastic element and the action part. The dispensing device 200 of this embodiment includes an active part 21 , an elastic element 40 and a retaining collar 30 sequentially from top to bottom. The elastic element 40 adopts a spring, and the two ends of the spring are respectively connected with the retaining collar 30 and the action part 21 , which is the same as the first embodiment, and this embodiment also adopts an adhesive connection method. The principle is the same as that of the first embodiment, since the holding collar 30 is fixed on the base 10 , the active part 21 can move with the syringe barrel 20 . It can be seen that the end of the spring 40 in contact with the holding collar 30 is the fixed end of the spring, a...

Abstract

The present invention provides a dispensing device, which includes a base, a dispensing syringe, at least one holding collar sleeved on the dispensing syringe and fixed on the base, at least one The active part of the outer wall of the dispensing syringe and at least one elastic element. One end of the dispensing syringe is provided with a dispensing needle. The elastic element is installed between the action part and the holding collar adjacent to the action part. Each elastic element is used for exerting an elastic action on the corresponding action part so that the dispensing syringe is in an elastic equilibrium state. Since the dispensing syringe is in an elastic equilibrium state, when the needle is touched, the dispensing syringe can be quickly retracted under the buffering action of the elastic element, so as to prevent the needle from hitting the needle due to hard contact.

Description

technical field [0001] The invention relates to a glue dispensing device, in particular to a glue dispensing device which can be used for lens module assembly. Background technique [0002] In the assembly process of mobile phone camera lens, in order to fix small parts such as lenses, gaskets, spacers and filters in the lens barrel, a glue dispensing process is usually carried out after the aforementioned small parts are loaded into the lens barrel to fix the small parts on the inside the barrel. see figure 1 , The glue dispensing process is completed by the glue dispensing device 10a cooperating with the rotating platform 20a. The traditional dispensing device 10a includes a holding device 11a and a dispensing syringe 12a fixedly installed on the holding device 11a. One end of the dispensing syringe barrel 12a is provided with a dispensing needle 13a for dispensing glue. When dispensing glue, the glue dispensing lens barrel 30a is set on the rotating platform 20a, the ...
