The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, a schematic structure of an optical filter assembly 100 according to an embodiment of the disclosure is shown. The filter assembly 100 may be applied in a camera assembly of a mobile terminal, or in a camera assembly of an Ipad, or in a wearable device. The filter assembly 100 includes a base 10 and a filter 20 coupled to the base 10.
Specifically, at least a portion of two opposite sides of the optical filter 20 is embedded in the base 10, and is integrally formed with the base 10. The portion where the optical filter 20 and the base 10 are integrally formed is the joint portion 12.
To better illustrate the improvement points of the present application, reference is now made to fig. 2, which is a schematic diagram of a prior art filter assembly 100 a. The end of the optical filter 20a of the related art is adhered to the base 10a by an adhesive layer 80 coated on the base. Since the contact portion between the optical filter 20a and the chassis 10a is limited and is generally only a general area of the end portion of the optical filter 20a, the optical filter 20a is easily broken due to poor adhesion and easy detachment. Further, the length b1 of the joint between the filter 20a and the base 10a is small, and the bonding strength is not strong.
In the application, because the end 22 of the optical filter 20 and the base 10 adopt an integrally formed structure, compared with the prior art, the ring Zhou Jun of the end 22 of the optical filter 20 is tightly engaged by the inner wall of the base 10 by adopting the integrally formed structure, compared with the prior art, the bonding force between the end 22 of the optical filter 20 and the base 10 can be well enhanced by the way of pasting the adhesive layer 80, and the probability that the optical filter 20 falls off or breaks due to small bonding force is greatly reduced.
Further, the length of the end portion of the filter 20 located in the chassis 10 is 0.25mm or more. By adopting the structure, the length of the optical filter 20 and the length of the optical filter positioned in the base 10 is far longer than the combination length of the prior art, and the combination strength of the optical filter and the optical filter can be further ensured.
The filter 20 functions to filter light waves. Specifically, the filter 20 may be one of blue glass, white glass, and a resin sheet.
In one embodiment, the thickness of one side of the joint 12 is 0.15-0.18mm. Referring to fig. 2, in the prior art, the thickness a1 of the side of the joint portion 12a corresponding to the present application is generally 0.3-0.38mm. With such an arrangement, the filter assembly 100 can be thinned as a whole, and thus the apparatus employing the filter assembly 100 can be made thinner as a whole, or space can be made free for other components. Specifically, the thickness of one side of the joint 12 may be 0.15mm or 0.18mm.
In an embodiment, the optical filter 20 is rectangular, and at least two opposite ends of the optical filter 20 are embedded in the base 10, or three or four ends of the optical filter may be embedded in the base 10, so as to enhance the bonding force between the two.
In another embodiment, the optical filter 20 is circular or elliptical, and the peripheral portion of the optical filter 20 is embedded in the base 10. Since all the end portions on the circumference of the optical filter 20 are embedded in the base 10 and tightly engaged by the inner wall of the base 10, the coupling force of the optical filter 20 and the base 10 can be well ensured.
Referring to fig. 3, the present application also provides a camera module 200 including the filter assembly 100 described in the above embodiments. The camera module 200 further includes a lens 30, and the lens 30 is disposed opposite to the optical filter 20. The filter 20 and the base 10 are integrally formed, so that the durability of the camera projection module 200 can be improved. In one embodiment, the camera module 200 further includes a motor 70 connected to the lens 30. The motor 70 is used for driving the lens 30 to move in a telescopic manner in the thickness direction of the optical filter 20, for example, during photographing of the camera module 200 or focusing of a photographed video.
Referring to fig. 4, in an embodiment, the camera projection module 200a further includes a chip 40 and a substrate 50 stacked together, and conductive pins 60 are disposed at the end of the chip 40 connected to the substrate 50 to realize electrical connection. The specific conductive pins 60 need to protrude toward the lens 30, where the end surface 24 of the combining portion 12 of the optical filter 20 and the base 10, which is far away from the lens 30, is far away from the center of the optical filter 20, so as to form the avoidance space 26. The relief space 26 is configured to receive the conductive pin 60. With such a structure, since the length of the combining portion 12 near the lens 30 is not reduced, the length of the combining portion 12 far away from the lens 30 is properly reduced, and the avoiding space 26 is set for accommodating the protruding portion of the conductive pin 60 toward the lens 30 on the premise that the combining strength of the optical filter 20 and the base 10 is strong. Therefore, the camera module 200a can be made thinner as a whole by adopting the structure. The specific conductive pins 60 may be gold wires or wires made of other materials.
In another embodiment, referring to fig. 5, the thickness of the bonding portion 12 of the camera module 200b near the chip 40 gradually increases from the end surface 24 near the center of the optical filter 20 toward the direction away from the center of the optical filter 20. With such a structure, a certain accommodating space 28 can be formed for the conductive pins 60 without reducing the bonding area between the optical filter 20 and the base 10. That is, the whole camera module 200b is made thinner on the premise of ensuring stronger bonding force between the optical filter 20 and the base 10.
Referring to fig. 6, the present application also provides a terminal 300, where the terminal 300 includes the camera modules described in the above embodiments, such as 200, 200a, and 200b. The terminal 300 may be a mobile phone, ipad, or a wearable device.
Referring to fig. 7, the present application further provides a method for manufacturing the optical filter assembly. The method comprises the following steps:
101: the end of the filter is placed into a mold.
102: and forming a base integrally formed with the end part of the optical filter in the mold by injection molding.
In one embodiment, the end portion of the optical filter is placed in the mold with a length greater than 0.25mm, so as to ensure that the length of the end portion of the optical filter, which is integrally formed after the base is formed, is greater than or equal to 0.25mm.
The structure of the filter assembly prepared by the method is identical to that of the filter assembly described in each embodiment.
Referring to fig. 8, the present application further provides a method for manufacturing a camera module. The method comprises the following steps:
201: the end of the filter is placed into a mold.
202: and forming a base integrally formed with the end part of the optical filter in the mold by injection molding.
203: and a lens is arranged on the opposite side of the optical filter.
The structure of the camera module prepared by the method is identical to that of the camera module described in each embodiment.
The filter assembly or the camera module manufactured by the method can ensure the bonding force between the filter and the base by adopting an integrated design, and greatly reduces the probability of falling and crushing the filter from the base.
The foregoing description is only of embodiments of the present application, and is not intended to limit the scope of the patent application, and all equivalent structures or equivalent processes using the descriptions and the contents of the present application or other related technical fields are included in the scope of the patent application.
