Description

Application of dispensing device

The present invention relates to a method of dispensing a dispensing device.

With the continuous development of technology, portable electronic devices, such as mobile phones, are becoming more and more widely used, and at the same time, they are becoming lighter, more beautiful, and more multifunctional. Among them, the camera function is an additional function of the popular mobile phone in recent years. The digital camera module used in mobile phones not only needs to meet the requirements of lightness and thinness, but also has high photographic performance, and the digital camera lens module assembly method is one of the main factors determining the photographic performance in the digital camera lens mode. In the assembly process, a dispensing device is used to glue the camera components. Therefore, improving the dispensing device will help improve the assembly capability and product yield.

A previous dispenser includes a tube, a needle, and a power source. The needle is connected to the pipe. The pipe is used to hold the glue and is connected to the power source. The needle is used to dispense the glue and the power source is used to allow the glue to flow out of the needle.

There is only one needle in the dispenser. In the process of dispensing, if the relative position of the needle and the dispensing position are deviated, there will be a phenomenon of uneven glue. Therefore, in the previous process, the glue filling process will be increased, resulting in Process time increases, which reduces assembly capacity and increases manufacturing costs.

In view of this, it is necessary to provide a method for dispensing a dispensing device that can improve product yield and reduce process.

A dispensing method comprising the steps of: providing a dispensing device comprising a dispenser and a holding mechanism connected to the dispenser, the holding mechanism for fixing and controlling the dispenser to perform a dispensing operation, the point The gluer includes: a first needle and a second needle, wherein the first needle and the second needle are used for dispensing glue; and a syringe, the syringe is connected to the first and second needles; a second needle is disposed on the same side of the syringe; and at least one of the first and second needles has a dispensing direction at an acute angle or a right angle to the axis of the needle; and a lens module to be dispensed is provided. The lens module includes a plurality of assembled optical components and a lens barrel for accommodating the optical components; the dispensing device is inserted into the lens barrel of the lens module to be dispensed; and the first needle is fixed to the lens The first dispensing position of the first needle, the second needle is fixed at the second dispensing position of the second needle; and the glue is applied to the first and second dispensing positions.

Since the dispensing method of the above dispensing device has the cooperation of the first and second needles, the rubberizing process is omitted, thereby simplifying the process, improving the assembly capability, and reducing the manufacturing cost.

1 is a schematic structural view of a dispensing device according to an embodiment of the present invention; and FIG. 2 is a structural schematic view of the dispensing device of FIG. 1 in a dispensing state of a camera lens to be assembled.

In order to further illustrate the present invention, a preferred embodiment will be described in detail below with reference to the drawings.

Referring to FIG. 1, a dispensing device according to an embodiment of the present invention includes a dispenser 10 and a holding mechanism 20. The dispenser 10 includes a first needle 11 for dispensing glue, a second needle 12, and a syringe 13 in communication with the first and second needles 11, 12. The syringe 13 is connected to the holding mechanism 20.

The first needle 11 and the second needle 12 are provided with flow passages 111, 121 for flowing the glue and placed on the same side of the syringe 13.

The direction in which the first needle 11 and the second needle 12 have at least one needle is at an acute or right angle to the axis of the barrel 13, and the angle of the acute angle is set as needed. For example, the direction of the first needle 11 is parallel to the axis of the barrel 13, the second needle 12 is at an acute angle or a right angle to the axis of the barrel 13, or the direction of the second needle 12 is parallel to the axis of the barrel 13, A needle 11 is at an acute or right angle to the axis of the syringe 13.

It can be understood that both the first needle 11 and the second needle 12 can be disposed at an acute angle or a right angle to the axis of the syringe 13.

The holding mechanism 20 can be a three-axis controller for fixing and controlling points The glue 10 is adapted to perform a dispensing operation.

Referring to FIG. 2, a dispensing device can be used to dispense a lens module 30 to be dispensed to facilitate assembly of components to be assembled. The lens module 30 includes a lens barrel 31 and a plurality of assembled optical elements 32.

Taking the lens module 30 to be dispensed as an example, the dispensing method includes the following steps: Step 1: providing a dispensing device as described above; Step 2: providing a lens module 30 to be dispensed, including a lens barrel 31 and a plurality of assembled optical components 32; Step 3: extending the first needle 11 and the second needle 12 of the dispensing device into the lens barrel 31; Step 4: fixing the first needle 11 to the first needle The first dispensing position of the second dispensing head 12 is fixed to the second dispensing position of the second needle 12; Step 5: After the dispensing device is fixed, the dispensing device is evenly rotated while the lens module 30 is rotating Pressing an appropriate amount of glue on the first and second dispensing positions; Step 6: taking out the dispensing device to complete the dispensing operation.

If you want to glue multiple components to be dispensed, repeat steps three to seven above.

The glue of the first needle 11 at the first dispensing position and the glue of the second needle 12 at the second dispensing position are brought together to achieve the purpose of fixing the optical component to be assembled.

The first dispensing position of the first needle 11 may be such that the outer side wall of the first needle 11 contacts the inner side wall of the lens barrel 31 and is close to a fixed position determined by the upper surface of the optical element 32 facing the first needle 11. This fixed position is set as needed.

The second dispensing position of the second needle 12 may be adjacent to the side wall of the lens barrel 31, and a fixed side of the outer surface of the second needle 12 is adjacent to the upper surface of the optical element 32 facing the second needle 12. Position, and the fixed position can be set as needed.

The dispensing device can uniformly apply the adhesive to the first and second dispensing positions under the joint action of the first needle 11 and the second needle 12, thereby ensuring sufficient between the components to be assembled. The lamination process is omitted, and the refining process is omitted, thereby simplifying the process and shortening the assembly time and improving the assembly capability.
