Description

Multiple groups of lenses and camera modules

technical field

This application relates to the field of camera modules, in particular, to multi-group lenses, multi-group lens camera modules and electronic equipment.

Background technique

As an important part of the camera module, the lens directly affects the imaging quality of the camera module. With the continuous development of intelligence, the requirements for camera modules continue to increase. For example, there are higher and higher requirements for high pixels in imaging, which also makes the number of lenses in the lens of camera modules continue to increase, such as reaching 5 to 6 piece.

In traditional lenses, multiple lenses are usually assembled in a lens barrel one by one. During the assembly process, there is inevitably a certain tolerance when each lens is assembled with the lens barrel, and finally the lens is assembled with the lens barrel to form a cumulative tolerance. , which is the assembly tolerance of a single lens. Therefore, the higher the number of lenses, the greater the cumulative tolerance, the lower the overall quality of the lens, and the lower the yield rate in the lens production process.

On the other hand, for traditional lenses, multiple lenses are assembled in the same lens barrel, and the relative positions of the lenses are fixed and cannot be adjusted. Once the lens is assembled in the lens barrel, the quality of the lens is determined, which also requires higher processing accuracy for the lens barrel and lens.

It is worth mentioning that for lenses with a small number of elements, the assembly tolerance of the elements has less influence. However, when the number of lenses increases, due to the incoming materials and assembly tolerances of each lens, lens barrel, spacer, etc., the assembly yield decreases while the imaging quality decreases, and the difficulty of lens assembly increases. Therefore, how to ensure good performance in the multi-element lens structure Imaging quality and the yield rate in the production process are an important aspect that needs to be studied.

It is also worth mentioning that the lens of the lens and the assembly relationship between the lens and the lens barrel directly affect the quality of the lens, and the camera module, especially the camera module used in some smart devices, such as smart phones, has a relatively small size. Therefore, how to combine the existing equipment requirements, make full use of the structure of the lens, and study the lens suitable for actual production and application are also aspects that need to be considered.

It should be understood that the first group unit 11 and the second group unit 12 can be assembled together in various ways. In one embodiment, the first group unit 11 and the second group unit 12 may be arranged sequentially along the same optical axis. In one embodiment, when the group units are assembled, the optical axis direction of the lenses in the first group unit 11 may be parallel to the optical axis direction of the lenses in the second group unit 12 .

In one embodiment, after the first group unit 11 and the second group unit 12 are assembled, the central axis of the first group unit 11 and the central axis of the second group unit 12 may be offset from each other by 0-15 μm. Herein, with reference to FIG. 1, for the convenience of measurement, the central axis of the first group unit 11 can be understood as the central axis of the optical surface 1101 closest to the second group unit 12 in the first group unit 11; It is understood as the central axis defined by the structural surface 1102 of the lens 1113 closest to the second group unit 12 . When the lowermost lens 1113 of the first group unit 11 and the first carrying body 1121 (such as the lens barrel) are tightly fitted, the central axis of the first group unit 11 can also be understood as the center defined by the inner surface of the first carrying body. axis.

Referring again to FIG. 1 , the first group unit 11 may further include an extension portion 1122 extending outward from the first carrying body 1121 . The extension part 1122 can extend from the outside of the first carrying body 1121 to the outside, so as to overlap the receiving part 1222 of the second group unit 12 . The extension portion 1122 integrally extends outward from the outside of the first bearing body 1121 . In some embodiments, the extension part 1122 can be a ring around the first bearing body 1121, extending outward from the first bearing body 1121 to form a ring-shaped visor structure, so as to overlap the second group unit through the ring-shaped brim structure. The receiving portion 1222 of 12 provides stable support for the first group unit 11 .

Referring to FIG. 1 , there may be an adjustable gap S2 between the bottom surface of the extension portion 1122 of the first group unit 11 and the top surface of the receiving portion 1222 of the second group unit 12 (see the enlarged schematic diagram of the dotted line in FIG. 1 ) .

It should be understood that the first group unit 11 and the second group unit 12 may be fixed in other ways, such as heat welding, ultrasonic welding, laser welding, etc., and the present application is not limited thereto.

Referring again to FIG. 1 , the first group unit 11 may include at least one spacer 113 . The spacer 113 cooperates with each first lens 111 to restrict the light passing through the first lens 111 and provide a predetermined light path. The uppermost lens 1111 , the middle lens 1112 and the lowermost lens 1113 of the first lens 111 are arranged in the first carrying body 1121 along the light path from top to bottom. In this embodiment, the first group unit 11 is provided with two spacers 113 , respectively disposed between the uppermost mirror 1111 and the middle mirror 1112 , and between the middle mirror 1112 and the lowermost mirror 1113 . The spacer 113 can also be disposed on the first lens 111 in the form of a coating.

In one embodiment, the spacer 113 can be arranged on the lower part of the lowermost lens 1113 of the first lens 111, so that when the first group unit and the second group unit are assembled, the bottom surface of the spacer 113 is in contact with the second group unit.

In this application, the adjustable gap is set according to the optical characteristics of the first lens and the second lens. By setting and reserving an adjustable gap before assembly, the adjustment of six degrees of freedom can be realized in the case of assembling the first group unit and the second group unit. When each group unit is assembled to form a multi-group lens, the overall optical performance of each lens in the multi-group lens can be adjusted by active calibration, so that the adjustable gap is formed into a solidified gap. When multi-group lenses are mass-produced, the curing gap can be different for each product.

In one embodiment, the size of the curing gap is such that the angle at which the first group unit can be inclined relative to the second group unit is less than or equal to 0.5°. It should be understood that the aforementioned inclination angle may include an inclination angle of six degrees of freedom of the first group unit relative to the second group unit in three-dimensional space. The six degrees of freedom refer to the degrees of freedom of movement along the three coordinate axes of x, y, and z and the degrees of freedom of rotation around these three coordinate axes in three-dimensional space.

In one embodiment, the reinforcing fixing groove 112112 may correspond to the outermost first lens 111 . For example, when there are two lenses in the first carrying body 1121 (for example, an upper lens and a lower lens), the reinforcing and fixing groove 112112 can reinforce and fix the lower lens. In the case that there are four lenses inside the first carrying body 1121 , the reinforcement fixing groove 112112 can reinforce and fix the fourth lens at the bottom.

Preferably, in some embodiments, the reinforcement fixing grooves 112112 are symmetrically distributed on the lower end of the first carrier body 1121, so as to provide a uniform force for the corresponding first lens 111, and prevent the bonding medium 13 from being subjected to the environment. When changes occur due to influence, the force acting on the first lens 111 is not uniform, for example, the force acting on the bonding medium 13 is not uniform when thermally expanded.

The reinforcing fixing groove 112112 can be designed in different shapes according to requirements, and its cross-sectional shape is, for example, wedge-shaped, triangular, trapezoidal, or rectangular. The reinforcing and fixing grooves 112112 can be arranged separately at intervals, or can be connected grooves, that is to say, form an integral annular groove, and the cross-section of the annular groove can be in different shapes.

Preferably, the depth of the reinforcing fixing groove 112112 is smaller than the thickness of the edge of the corresponding lowermost lens, so as to prevent a gap between the reinforcing fixing groove 112112 and the edge of the top surface of the lens, allowing glue to enter the lens through the gap.

In this embodiment and FIG. 1 , the reinforcing and fixing grooves 112112 have a trapezoidal structure, and the four reinforcing and fixing grooves 112112 are distributed symmetrically. Certainly, in other embodiments of the present application, the reinforcing fixing grooves 112112 may also be of other shapes and other numbers, such as three, five, or more than five, etc., and the present application is not limited thereto.

In one embodiment, the reinforcing fixing groove 112112 can also be an annular structure (not shown), and the inner wall of the ring is inclined, so as to facilitate the application of the adhesive medium 13 . That is to say, the reinforcing fixing groove 112112 can provide a larger opening, so that it is convenient to add the bonding medium 13 through, for example, a needle to avoid contaminating the surface of the corresponding first lens 111, and the bonding medium 13 can flow along the inclined ring structure to the corresponding side edge of the first lens 111, so as to be stably fixed from the side edge of the first lens 111.

In one embodiment, the depth of the reinforcing fixing groove may be greater than or equal to 0.15 mm. In one embodiment, the opening width of the reinforcing fixing groove may be greater than or equal to 0.2 mm. In one embodiment, the corresponding wall thickness of the reinforcing fixing groove may be greater than or equal to 0.1 mm.

In one embodiment, the first carrier body 1121 of the first group unit 11 may include a reinforced fixing area (not shown) penetrating through the sidewall of the first carrier body 1121 for accommodating the bonding medium 13, Thus, the first lens 111 is reinforced and fixed.

The second group unit 12 may include a second carrying body 1221 and at least one second lens 121 accommodated in the second carrying body 1221 . The first lens 121 may include three lenses, namely, an uppermost lens 1211 , a middle lens 1212 and a lowermost lens 1213 .

The second group unit 12 can also include a receiving portion 1222 connected to the second carrier body 1221, so as to cooperate with the first carrier body 1121 of the first group unit 11, and to receive the first load of the first group unit 11.

The first group unit 11 may further include an extension portion 1122 extending outward from the first carrying body 1121 so as to overlap the receiving portion 1222 of the second group unit 12 .

Except for the extension part 1122 and the receiving part 1222 , the multi-group lens 100 shown in FIG. 3 is basically the same as the multi-group lens 100 shown in FIG. 1 , so the description of other components is omitted.

As shown in FIG. 3 and FIG. 4 , the extension portion 1122 of the first bearing body 1121 may include a protruding portion 11222 protruding downward, and the receiving portion 1222 of the second group unit 12 may include a matching groove 12221 recessed downward.
