[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0029] As described in the background technology, in actual applications, the camera module often has the problem of gold line glare. Improper size control of blue glass will cause gold line glare. Therefore, the silk screen printing size design of blue glass will become an important issue. A large size will lead to dark edges, and a small size will lead to gold line glare. We often use silk screen printing on blue glass to reduce light scattering and reflection, thereby improving image clarity and image quality, but too much silk screen printing will affect the problem of dark corners and dark edges of the camera module.
[0030] Blue glass is a transparent glass material that appears blue. Color formation principle: Blue glass appears blue because it can transmit blue light and absorb or block light of other colors. Unlike opaque objects, the color of transparent objects is determined by the color of the light transmitted through them. Blue glass appears blue by transmitting only blue light and filtering out light of other colors.
[0031] Blue glass screen printing of camera modules is a process technology, which is mainly used for the decoration and protection of smartphone camera modules.
[0032] In order to solve this technical problem, the utility model provides an attachment base for a camera module.
[0033] Specifically, please refer to Figure 1-Figure 4 , the attachment base of the camera module includes:
[0034] A base body 1, with a base groove 2 on its surface;
[0035] A multi-layer defining portion 3, which is disposed at the bottom of the base groove 2 and can be connected to the blue glass 4;
[0036] When the light passes through the blue glass 4 and reaches the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of the light inside the base.
[0037] The utility model can reduce the reflection and refraction of light inside the base by the cooperation of the multi-layer limiting part 3 and the blue glass 4. Specifically, the blue glass 4 is directly placed on the multi-layer limiting part 3. When the light passes through the blue glass 4 and is transmitted to the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of light inside the base.
[0038] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0041] Please refer to Figure 1-Figure 3 , the attachment base of the camera module includes:
[0042] A base body 1, with a base groove 2 on its surface;
[0043] A multi-layer defining portion 3, which is disposed at the bottom of the base groove 2 and can be connected to the blue glass 4;
[0044] When the light passes through the blue glass 4 and reaches the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of the light inside the base.
[0045] The utility model can reduce the reflection and refraction of light inside the base by the cooperation of the multi-layer limiting part 3 and the blue glass 4. Specifically, the blue glass 4 is directly placed on the multi-layer limiting part 3. When the light passes through the blue glass 4 and is transmitted to the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of light inside the base.
[0046] The attachment base of the camera module provided in Example 1 is further optimized, and the attachment base of the camera module includes:
[0047] A base body 1, with a base groove 2 on its surface;
[0048] A multi-layer defining portion 3, which is disposed at the bottom of the base groove 2 and can be connected to the blue glass 4;
[0049] When the light passes through the blue glass 4 and reaches the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of the light inside the base.
[0050] The utility model can reduce the reflection and refraction of light inside the base through the cooperation of the multi-layer defining part 3 and the blue glass 4. Specifically, the blue glass 4 is directly placed on the multi-layer defining part 3. When the light passes through the blue glass 4 and is transmitted to the bottom of the base groove 2, the multi-layer defining part 3 can change the propagation path of the light and reduce the reflection and refraction of light inside the base. The multi-layer defining part 3 includes a plurality of grooves 5, all of which are arranged at the bottom of the base groove 2 and the depth is arranged to decrease from the inside to the outside.
[0051] In some specific embodiments, the spacing between adjacent grooves 5 in the length direction is smaller than the spacing between adjacent grooves 5 in the width direction.
[0052] In some specific embodiments, the corners of each groove 5 are arc-shaped.
[0053] In some specific implementations, the edge of the base groove 2 adopts an arc transition to reduce the scattering of light at the edge.
[0054] For details, please refer to Figure 1 and Figure 2 , the multi-layer limiting part 3 can choose two A and B. The base body 1 adopts a two-layer structure design, and each layer is arranged with a specific spacing. The blue glass 4 is placed in the appropriate area. The A groove and the B groove are two-layer designs. The depth of the B groove is 0.2mm, and the X and Y directions (length direction and width direction) are 0.08 and 0.1mm away from the A groove respectively. This design can effectively change the propagation path of light and reduce the reflection and refraction of light inside the base. For example, after the specified blue glass 4 is attached to the A groove, the glare problem exists because the silk screen size of the blue glass 4 is too small. At this time, the B groove can solve the problem of glare in the camera module caused by the small silk screen. That is, by attaching it to the A groove, the B groove can block the glare. Similarly, the B groove is attached, and the C groove (set in the A groove) can block the glare caused by the small silk screen.
[0055] The edge of the base groove 2 adopts an arc transition to reduce the scattering of light at the edge and further reduce the generation of gold line glare.
[0056] The attachment base of the camera module provided in Example 1 or 2 is further optimized, and the attachment base of the camera module includes:
[0057] A base body 1, with a base groove 2 on its surface;
[0058] A multi-layer defining portion 3, which is disposed at the bottom of the base groove 2 and can be connected to the blue glass 4;
[0059] When the light passes through the blue glass 4 and reaches the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of the light inside the base.
[0060] The utility model can reduce the reflection and refraction of light inside the base through the cooperation of the multi-layer limiting part 3 and the blue glass 4. Specifically, the blue glass 4 is directly placed on the multi-layer limiting part 3. When the light passes through the blue glass 4 and is transmitted to the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of light inside the base. A limiting part is provided on the base body 1 to limit the position of the blue glass 4.
[0061] When the blue glass 4 is placed, it is easy to be misplaced due to the size of the groove 5 , so the position of the blue glass 4 can be limited by setting a limiting portion.
[0062] In some specific embodiments, the limiting portion includes a plurality of scale marking strips 6 disposed at the bottom of the base groove 2 , and all scale marking strips 6 are distributed around the multi-layer limiting portion 3 according to a set number.
[0063] In some specific implementations, the scale mark 6 is a line segment or a quadrilateral frame.
[0064] Specifically, when the scale bar 6 is a line segment, you can choose Figure 3 As shown in the arrangement, when the blue glass 4 is attached to the groove A, the position can be limited by the position of the top projection of the blue glass 4 on the scale strip 6.
[0065] When the scale marking strip 6 is a quadrilateral frame, the position of the blue glass 4 can be determined by the overlap between the top projection of the blue glass 4 and the quadrilateral frame.
[0066] The attachment base of the camera module provided in the above embodiments is further optimized, and the attachment base of the camera module includes:
[0067] A base body 1, with a base groove 2 on its surface;
[0068] A multi-layer defining portion 3, which is disposed at the bottom of the base groove 2 and can be connected to the blue glass 4;
[0069] When the light passes through the blue glass 4 and reaches the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of the light inside the base.
[0070] The utility model can reduce the reflection and refraction of light inside the base through the cooperation of the multi-layer limiting part 3 and the blue glass 4.

When the light passes through the blue glass 4 and is transmitted to the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of light inside the base. The base body 1 is provided with a limiting part for limiting the position of the blue glass 4. When the blue glass 4 is placed, due to the size of the groove 5, the blue glass 4 is prone to misalignment. Therefore, the position of the blue glass 4 can be limited by the provided limiting part.
[0071] The limiting portion further includes a release film 7 disposed on the other side surface of the base body 1 to further assist in positioning the blue glass 4 .
[0072] The release film 7 can be torn open, and a line segment or a quadrilateral frame can also be provided on the release film 7 to further assist in positioning the blue glass 4 .
[0073] In some specific embodiments, the top projection area of the release film 7 is not less than the top projection area of the base body 1 , and a plurality of positioning frames 8 arranged from the inside to the outside are provided on the surface of the release film 7 .
[0074] When the blue glass 4 is being bonded, the position of the blue glass 4 can be determined by the top view projection of the blue glass 4 on the release film 7 .
[0075] The use process of the attachment base of the camera module provided by the utility model is as follows:
[0076] The utility model can reduce the reflection and refraction of light inside the base by the cooperation of the multi-layer limiting part 3 and the blue glass 4. Specifically, the blue glass 4 is directly placed on the multi-layer limiting part 3. When the light passes through the blue glass 4 and is transmitted to the bottom of the base groove 2, the multi-layer limiting part 3 can change the propagation path of the light and reduce the reflection and refraction of light inside the base.
