Description

Assembling the parallelism detection device and its system

This creation is about lens assembly, especially an assembly parallelism detection device and its system.

With the development of technology, mobile phones have been widely used in people's daily life, and most of the mobile phones are equipped with camera lenses for taking pictures or fingerprint recognition.

When assembling the lens, the parallelism between the lens assembly suction nozzle and the lens barrel placement platform determines the parallelism of the lens assembly, and the higher the resolution of the lens, the smaller the parallelism requirement for lens stacking, the better. Therefore, it is extremely important to adjust the parallelism between the nozzle and the platform. The current adjustment method is usually to use the gauge head to touch the suction nozzle first and move the gauge. Adjusting the movement amount to the minimum indicates that the level adjustment is completed, and then moving the gauge probe to the platform and moving it also adjusts the movement amount to the minimum. After the adjustment is completed, it means that the parallelism between the two is in the best state. However, the currently used contact gauge is a single-point contact, and the measurement is a line. If the area is large, it needs to be measured multiple times.

In view of this, this creation proposes a lens assembly parallelism adjustment system, which generates a parallel light through an optical collimator to correct the parallelism between the assembly nozzle and the platform. This creation is an optical non-contact adjustment system. The lens assembly parallelism adjustment system proposed by this creation has higher accuracy than the method of using a contact scale.

The second reflective element is arranged on the second assembly element, and has a second reflective surface to reflect the second incident light to generate second reflected light, and the first reflective surface faces the second reflective surface. The collimator is disposed between the first reflective element and the second reflective element. The collimator includes a light entrance, a beam splitter, a first light exit, a second light exit and an observation window. The light entrance receives the specified light. The beam splitter divides the specified light into the first incident light and the second incident light. The first light outlet is used for emitting the first incident light to the first reflection element and receiving the first reflected light. The second light outlet is used for emitting the second incident light to the second reflection element and receiving the second reflected light, and the light output direction of the first light output port is opposite to the light output direction of the second light output port.
