Description

Capturing lens of image sensor and assembly and manufacturing method thereof

technical field

The invention relates to a capture lens of an image sensor and a manufacturing method thereof, especially to a lens in which a lens barrel and a lens group can be assembled in advance, and then assembled with a matching lens barrel seat and lens seat, and the lens Lens assembly manufacturing method.

Background technique

As shown in Figure 3, the common image sensor capture lens has a lens holder 81, and the lens holder 81 is arranged on an image sensing chipset 9, and the lens holder 81 is connected with a lens holder 82, and the lens holder 82 has a The accommodating portion 821 is embedded with a lens group 83 inside the accommodating portion 821 .

Since the appearance of the lens holder 81 and the lens holder 82 will change due to the image sensors being installed in different devices (such as: network cameras, digital cameras, etc.), for image sensor manufacturers, the image sensors of the same specification Chip set 9 and lens set 83 often need to be combined with lens holder 81 and lens holder 82 of different shapes. Furthermore, after the lens group 83 is embedded in the lens seat 82 , it is necessary to perform detection and adjustment of optical characteristics, and this detection and adjustment procedure is relatively cumbersome.

Therefore, when manufacturing the image sensor, the manufacturer of the image sensor needs to assemble the lens holder 82 and the lens group 83 one by one according to the required quantity after receiving the order from the customer, and then carry out the detection and adjustment of the optical characteristics. The lens holder 82 is combined with the lens holder 81 together. The structure of the existing image sensor capture lens determines that its manufacturing and assembly process can only start after the customer places an order. This will lead to problems such as prolonging the process time and prolonging the delivery time. , and it is difficult to improve the manufacturing efficiency, so it is necessary to improve it.

Contents of the invention

In order to solve the problems of existing image sensor capture lens manufacturing, long assembly time, and cumbersome detection and adjustment procedures, the main purpose of the present invention is to provide an image sensor capture lens and its assembly and manufacturing method. The capture lens assembly is simple, the time is short, and the efficiency is high.

In order to achieve the above object, the present invention adopts the following technical solutions: a pickup lens of an image sensor, the lens includes a lens mount, the lens mount is connected with a hollow lens barrel seat, and the lens barrel seat can be displaced in the lens mount; A section of the lens barrel seat adjacent to the lens seat has a joint part, and a lens barrel is arranged in the joint part, and a lens group is embedded in the lens barrel; Capture footage.

The central part of the lens holder has a hollow accommodating part for accommodating the image sensing chip; a connecting part for connecting with the lens barrel holder is provided at the end of the lens holder away from the image sensing chip.

An end of the joint portion of the lens barrel seat away from the lens seat has a blocking portion for positioning when the lens barrel is assembled.

The lens barrel has an inwardly convex retaining edge for lens assembly and positioning.

The method for assembling the above-mentioned image sensor capture lens includes the following steps:

a. Embed the lens group in a lens barrel, and perform detection and adjustment of optical characteristics;

b. setting the lens barrel assembly completed in step a in the joint of a lens barrel seat;

c. Connect the lens barrel base completed in step b with the lens base to complete the assembly process of the lens.

Because the present invention has a joint part designed in the lens barrel seat, the lens barrel assembly with the lens group embedded inside is arranged therein, so that the lens barrel and the lens group can be assembled in advance, and the detection and adjustment of optical characteristics can be carried out . In other words, for image sensor manufacturers, the assembly work of the lens barrel and the lens group can be pre-assembled before the customer places an order, and the detection and adjustment of optical characteristics can be performed. According to the needs, select the appropriate lens holder and lens barrel holder, combine with the lens group and lens barrel that have been assembled, tested and adjusted, and then the assembly of the image sensor and the lens can be completed. Compared with the previous technology, all assembly work is easy It needs to be carried out after the customer places an order, and the invention can obviously improve the manufacturing efficiency effectively.

Detailed ways

Please refer to Fig. 1 and Fig. 2, the image sensor capture lens disclosed by the invention includes a lens mount 1, and the central part of the lens mount 1 has a hollow accommodating part 11 for accommodating the image sensor chipset 2 and connecting with it combined. A connecting portion 12 is provided at the end of the lens mount 1 away from the image sensor chip 2 for connecting with a hollow lens barrel base 3 , and the lens barrel base 3 can be displaced in the lens mount 1 . A section of the lens barrel base 3 adjacent to the lens base 1 has a joint portion 31 for a lens barrel 4 to be assembled therein. The joint portion 31 of the lens barrel base 3 has a stop portion 32 at the end far away from the lens base 1 for positioning against the lens barrel 4 when it is assembled, and a lens group 5 is embedded in the lens barrel 4, and the lens barrel 4 It has an inwardly convex retaining edge 41 for positioning when the lens group 5 is embedded. The above-mentioned lens holder 1, lens barrel holder 3, lens barrel 4, and lens group 5 together form an image sensor capture lens.

Accordingly, the manufacture of the image sensor capture lens assembly of the present invention includes the following steps:

a. Embed the lens group in a lens barrel, and perform detection and adjustment of optical characteristics;

b. setting the lens barrel assembly completed in step a in the joint of a lens barrel seat;

c. Connect the lens barrel base completed in step b with the lens base to complete the assembly process of the lens.

Because the present invention is designed with the joint portion 31 in the lens barrel seat 3, the lens barrel 4 with the lens group 5 embedded therein is assembled therein, so that the lens barrel 4 and the lens group 5 can be pre-assembled and completed, and optical Characteristic detection and adjustment.
