Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a camera module, an electronic device, and a method for manufacturing the camera module. Background Art

[0002] As people's demand for electronic devices (such as mobile phones, tablets, etc.) grows year by year, electronic devices have more functions. For example, electronic devices generally have photography and video functions, which require camera modules for image acquisition. Camera modules include lenses and lenses. At present, most lenses on the market are matched with lenses through a series of tolerance chains, and many components rely on manual assembly by production line employees. Therefore, the material tolerance plus the assembly tolerance causes a deviation between the light transmission center on some lenses and the center of the lens. Summary of the invention

[0003] The embodiments of the present application provide a camera module, an electronic device, and a method for manufacturing the camera module, which are used to solve the problem of deviation between the light transmission center on the lens and the center of the lens.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] In a first aspect, a camera module is provided. The camera module includes a lens and a lens. The lens includes a body and a first ink layer and a second ink layer located on the body. The body has a first light-transmitting area and a light-blocking area. The first ink layer and the second ink layer are both located in the light-blocking area, the second ink layer is arranged around at least part of the edge of the first light-transmitting area, and the second ink layer covers the edge of the first ink layer close to the first light-transmitting area. The lens includes a boss, the boss surrounds a second light-transmitting area, and the second light-transmitting area is arranged opposite to the first light-transmitting area.

[0006] The second ink layer covers the edge of the first ink layer near the first light-transmitting area, that is, the second ink layer includes a first part and a second part, the second ink layer covers the inner edge of the first ink layer, so that the first part overlaps with the first ink layer, and the second part extends from the inner edge of the first ink layer to the direction away from the outer edge of the first ink layer, that is, extends to the center close to the first light-transmitting area. By forming the first part by covering the inner edge of the first ink layer with the second ink layer, it is avoided that the gap between the first ink layer and the second ink layer causes a light-transmitting gap, so that the first ink layer and the second ink layer can be seamlessly connected, and the first ink layer and the second ink layer are no different in the direction from the lens body to the lens. The second part increases the area of ​​the ink covering the body to form the first light-transmitting area. The second light-transmitting area is arranged relative to the first light-transmitting area, so that the light-transmitting center of the lens coincides with the center of the lens, solves the eccentricity problem of the camera module, and improves the aesthetics of the camera module.

[0007] In a possible implementation of the first aspect, the boss includes a mounting surface facing the main body, and a first side surface and a second side surface respectively connected to opposite sides of the mounting surface. The orthographic projection of the mounting surface on the main body coincides with the orthographic projection of the second ink layer on the main body, and the first side surface and the second side surface are arranged at an angle and approach each other in a direction away from the mounting surface. In this way, when too much ink is applied to the mounting surface, the excess ink flows downward along the first side surface or the second side surface by its own gravity and adheres to the first side surface or the second side surface to achieve visual hiding. By arranging the first side surface and the second side surface at an angle, compared with the first side surface and the second side surface extending directly in a direction perpendicular to the mounting surface, the area will be larger and more ink can be hidden.

[0008] In a possible implementation of the first aspect, a third ink layer is provided on the mounting surface. The orthographic projection of the third ink layer on the body is located within the orthographic projection region of the second ink layer on the body. Some ink will remain on the mounting surface, and the ink remaining on the mounting surface is the third ink layer, and the orthographic projection of the third ink layer on the body is located within the orthographic projection region of the second ink layer on the body.

[0009] In a possible implementation of the first aspect, a deinking layer is provided on the mounting surface, and the deinking layer includes a plurality of deinking structures. The cross-sectional area of ​​each deinking structure on the side away from the boss is smaller than the cross-sectional area on the side close to the boss. The cross-sectional area of ​​the upper end of the deinking structure is smaller than the cross-sectional area of ​​the lower end, thereby reducing the contact area between the deinking layer and the ink, so that the ink can be more easily separated from the mounting surface and transferred to the lens, thereby improving the success rate of transfer.

[0010] In a possible implementation of the first aspect, the camera module further includes a bracket. The bracket is formed with a through hole and a protrusion located on the wall of the through hole. The protrusion divides the through hole into a first connecting section and a second connecting section that are connected. The lens is installed in the first connecting section, and the lens is at least partially installed in the second connecting section. In this way, by setting the first connecting section to install the lens and setting the second connecting section to install the lens, the bracket can fix the relative position of the lens and the lens, so that the deviation between the lens and the lens is reduced.

[0011] In a possible implementation of the first aspect, the camera module further includes a pasting structure, which is located between the protrusion and the lens. The pasting structure includes a compressible layer and a pasting layer. The pasting layer is located between the compressible layer and the lens, and is pasted to the compressible layer and the lens respectively. The compressible layer is provided in the pasting structure, and the compressible layer can push the lens to move upward, thereby improving the efficiency of transfer.

[0012] In a possible implementation of the first aspect, there are multiple through holes, which are arranged at intervals, and there are multiple lenses, which are consistent in number and arranged one-to-one with the lenses. In this way, one bracket can fix multiple lenses.

[0013] In a possible implementation of the first aspect, an adhesive is disposed between the first ink layer and the second ink layer. The adhesive is disposed on the surface of the second ink layer so that the second ink layer can be more easily connected to the lens, thereby improving the success rate of transfer.

[0014] In a possible implementation of the first aspect, a first magnet is disposed in the boss, and a second magnet is disposed in the second ink layer. The first magnet and the second magnet have the same polarity. In this way, the first magnet and the second magnet repel each other, and the force of the mutual repulsion between the first magnet and the second magnet makes it easier for the second ink layer to detach from the boss and transfer to the lens, thereby improving the success rate of transfer.

[0015] In a second aspect, an electronic device is provided, the electronic device comprising a housing and a camera module, the camera module being a camera module according to any technical solution of the first aspect. The housing has a third light-transmitting area, and the first light-transmitting area and the third light-transmitting area are at least partially arranged opposite to each other.

[0016] Since the electronic device provided in the present application includes a camera module of any technical solution of the first aspect above, the two can solve the same technical problem and achieve the same effect.

[0017] In a third aspect, a method for manufacturing a camera module is also provided, the manufacturing method comprising the following steps: providing a lens, the lens comprising a boss. Applying ink on the boss to form an ink layer to be transferred on the boss. Providing a lens, the lens comprising a body and a first ink layer located on the body, the body having an initial light-transmitting area and an initial light-blocking area, and the first ink layer is located in the initial light-blocking area. At least part of the ink layer to be transferred is transferred to the body to form a second ink layer on the lens, the initial light-transmitting area is reduced and the first light-transmitting area is formed. The second ink layer covers the edge of the first ink layer close to the initial light-transmitting area.

[0018] Transfer is a printing technology that transfers the image and text on the intermediate carrier to the substrate using corresponding pressure. That is, a certain pressure is applied so that the lower surface of the body contacts the ink layer to be transferred, and the ink layer to be transferred can be separated from the boss and transferred to the body. The ink layer to be transferred is transferred to the body to form a second ink layer, and the second ink layer covers the inner edge of the first ink layer. That is, the second ink layer includes a first part and a second part, and the second ink layer covers the inner edge of the first ink layer, so that the first part overlaps with the first ink layer, and the second part extends from the inner edge of the first ink layer to the direction away from the outer edge of the first ink layer, that is, extends to the center of the first light-transmitting area. By covering the inner edge of the first ink layer with the second ink layer to form the first part, the light-transmitting gap caused by the interval between the first ink layer and the second ink layer is avoided, so that the first ink layer and the second ink layer can be seamlessly connected, and there is no difference between the first ink layer and the second ink layer when looking from the lens body to the lens. The initial light-blocking area is enlarged by the second part, and the initial light-transmitting area is reduced to form a first light-transmitting area. At this time, the second light-transmitting area is arranged relative to the first light-transmitting area, so that the light-transmitting center of the lens coincides with the center of the lens, thereby solving the eccentricity problem of the camera module and improving the aesthetics of the camera module.

Figure 1 restrictions.

[0046] See also Figure 2 , the electronic device 100 may include a screen 10, a housing 20, a camera module 30, a mainboard 40 and a camera decorative cover 50. In some other examples, the electronic device 100 may also not include the camera decorative cover 50.

[0047] The screen 10 can be used to display images, videos, etc. The screen 10 may include a transparent cover plate 11 and a display screen 12. The transparent cover plate 11 and the display screen 12 are stacked. The transparent cover plate 11 is mainly used to protect the display screen 12 and prevent dust. The material of the transparent cover plate 11 includes but is not limited to glass. The display screen 12 can be a flexible display screen or a rigid display screen.

[0048] The housing 20 may be used to protect the internal electronic components of the electronic device 100. The housing 20 may include a back cover 21 and a frame 22. The back cover 21 may be located on a side of the display screen 12 away from the light-transmitting cover plate 11, the frame 22 may be located between the back cover 21 and the light-transmitting cover plate 11, and the frame 22 may be fixed to the back cover 21.

[0049] Exemplarily, the frame 22 can be fixedly connected to the back cover 21 by adhesive. The frame 22 can also be an integrally formed structure with the back cover 21, that is, the frame 22 and the back cover 21 are an integral structure.

The internal accommodation space can accommodate the display screen 12.

[0050] In some embodiments, see Figure 2 The electronic device 100 may further include a middle plate 23. The middle plate 23 is fixed to the inner surface of the frame 22. For example, the middle plate 23 and the frame 22 may be made of metal materials, and the middle plate 23 may be fixed to the frame 22 by welding. The middle plate 23 may also be an integrally formed structure with the frame 22. The middle plate 23 is used as the structural "skeleton" of the electronic device 100, and the camera module 30 may be fixed and supported on the middle plate 23 by means of threaded connection, clamping, welding, etc.

[0051] The camera module 30 can be used to take photos / videos.

[0052] The camera module 30 can be used as a rear camera module or a front camera module.

[0053] The camera module 30 may be a periscope camera module or a vertical camera module.

[0054] In some embodiments, see Figure 2 The camera module 30 can be fixed on the surface of the middle plate 23 close to the back cover 21. The light incident surface of the camera module 30 faces the back cover 21. The back cover 21 has a third light-transmitting area 24. The third light-transmitting area 24 is at least partially arranged opposite to the camera module 30. The light can pass through the third light-transmitting area 24 and enter the camera module 30, so that the camera module 30 can collect images.

[0055] The camera decorative cover 50 covers and is fixed to the third light-transmitting area 24. The camera decorative cover 50 can be used to protect the camera module 30. In this embodiment, the camera module 30 can be used as a rear camera module 30 of the electronic device 100. The camera decorative cover 50 has a light-transmitting hole 51, which is used to allow light to pass through the camera decorative cover 50 and then enter the light-incident surface of the camera module 30.

[0056] In some other embodiments, the camera module 30 can be fixed to the surface of the middle plate 23 close to the light-transmitting cover plate 11. The light-entering surface of the camera module 30 faces the light-transmitting cover plate 11. A light path avoidance hole can be provided on the display screen 12. The light path avoidance hole allows the scene light to pass through the light-transmitting cover plate 11 and then enter the light-entering surface of the camera module 30. In this way, the camera module 30 can be used as a front camera module 30 of the electronic device 100.

[0057] For example, the main board 40 can be fixed to the middle board 23 by means of threaded connection, snap connection, etc.

[0058] See also Figure 3 , Figure 3 for Figure 1 and Figure 2 The internal circuit diagram of the electronic device 100 is shown. The electronic device 100 also includes a computing control unit 41. For example, the computing control unit 41 can be arranged on the mainboard 40. The computing control unit 41 can also be arranged on other circuit boards in the electronic device 100, such as on a circuit board where a universal serial bus (USB) device is located. In some embodiments, the computing control unit 41 is an application processor (AP). The computing control unit 41 is electrically connected to the camera module 30. The computing control unit 41 is used to receive and process electrical signals containing image information from the camera module 30.

[0059] In some embodiments, see Figure 4 The camera module 30 includes a lens 31 and a lens 32. An ink layer is usually provided on the lens 31 by silk screen printing, and the ink layer divides the lens 31 into a light-transmitting area and a non-light-transmitting area, and the area where the ink layer is located is the non-light-transmitting area. Silk screen printing is screen printing, which refers to using a silk screen as a base and making a silk screen printing plate with images through a photosensitive platemaking method, and printing is performed based on the basic principle that the mesh holes of the image part of the silk screen printing plate can pass the ink, while the mesh holes of the non-image part cannot pass the ink. When printing, ink is poured into one end of the silk screen printing plate, and a certain pressure is applied to the ink part on the silk screen printing plate with a scraper, and the scraper moves at a constant speed toward the other end of the silk screen printing plate. During the movement, the ink is squeezed from the mesh holes of the image part to the substrate by the scraper.

[0060] See also Figure 4 , the assembly relationship between the lens 31 and the lens 32. Figure 4As shown, the camera module 30 also includes a first fixing frame 36 and a second fixing frame 37. The lens 32 is positioned and fixed by the first fixing frame 36. The first fixing frame 36 is provided with a first fixing hole 361 that penetrates through it, and the lens 32 is at least partially installed in the first fixing hole 361. The lens 31 is positioned and fixed by the second fixing frame 37. The second fixing frame 37 is provided with a second fixing hole 372 that penetrates through it. The second fixing hole 372 is connected to the first fixing hole 361, and the lens 31 is installed in the second fixing hole 372. The first fixing frame 36 includes a positioning column 362, and the second fixing frame 37 is provided with a third fixing hole 373, and the third fixing hole 373 can be a blind hole. The positioning column 362 is inserted into the third fixing hole 373, so as to realize the positioning connection between the first fixing frame 36 and the second fixing frame 37.

[0061] The assembly process of the lens 31 and the lens 32 is as follows: the lens 32 is at least partially installed in the first fixing hole 361, so that the lens 32 is positioned and fixed by the first fixing frame 36. Then, the positioning column 362 is inserted into the third fixing hole 373, so as to achieve the positioning connection between the first fixing frame 36 and the second fixing frame 37. Then, the lens 31 is installed in the second fixing hole 372, so that the lens 31 is positioned and fixed by the second fixing frame 37.

[0062] The minimum tolerance chain between the light transmission center of the lens 31 and the center of the lens 32 is mainly composed of: ① The dimension from the center of the lens 32 to its edge, the material tolerance is ±0.05mm. ② The lens 32 is at least partially installed in the first fixing hole 361, and the gap dimension from the edge of the lens 32 to the hole wall of the first fixing hole 361, the assembly tolerance is ±0.07mm. ③ The dimension from the hole wall of the first fixing hole 361 to the center of the positioning column 362, the material tolerance is ±0.05mm. ④ The dimension from the center of the positioning column 362 to the edge of the positioning column 362, the material tolerance is ±0.05mm. ⑤ The positioning column 362 is inserted into the third fixing hole 373, and the gap dimension from the edge of the positioning column 362 to the hole wall of the third fixing hole 373, the assembly tolerance is ±0.05mm. ⑥ The dimension from the hole wall of the third fixing hole 373 to the hole wall of the second fixing hole 372, the material tolerance is ±0.05mm. ⑦ The lens 31 is installed in the second fixing hole 372. The gap size from the hole wall of the second fixing hole 372 to the edge of the lens 31 has an assembly tolerance of ±0.05mm. ⑧ The size from the edge of the lens 31 to the light-transmitting hollow of the lens 31 has a material tolerance of ±0.05mm.

[0063] See also Figure 5, the above material tolerance and assembly tolerance are brought into the two-dimensional tolerance analysis framework, and the statistical tolerance is ±0.3mm. The light transmission center of the lens 31 and the center of the lens 32 have a large deviation, which is easy to produce eccentricity. In addition, in order to meet the characteristics of appearance, easy assembly, and disassembly, the tolerance chain of the current mobile phone projects of various manufacturers is constantly lengthening.

[0064] In view of the assembly tolerance mentioned above, the working logic of the automatic assembly equipment of lens 31 is as follows: photograph lens 32 and lens 31 respectively to obtain the contour trajectories corresponding to lens 32 and lens 31; while keeping the position of lens 32 fixed, control the movement of lens 31 according to the center distance between lens 32 and lens 31, so that the light transmission center on lens 31 coincides with the center of lens 32 as much as possible. However, the automatic assembly process will be affected by the tolerance chain mentioned above, resulting in a deviation between the light transmission center of lens 31 and the center of lens 32. When the light transmission area of ​​lens 31 is circular and the cross section of lens 32 is circular, the light transmission center of lens 31 deviates from the center of lens 32, which can be understood as an eccentricity between lens 31 and lens 32.

[0065] See also Figure 6 In a camera module 30 provided in the present application, the camera module 30 may include a lens 31 and a lens 32. The lens 31 is arranged opposite to the lens 32. In this embodiment, the light-transmitting area of ​​the lens 31 is circular for example.

[0066] The lens 31 includes a main body 311 and a first ink layer 312 and a second ink layer 313 located on the main body 311. The main body 311 has a first light-transmitting area 315 and a light-blocking area 316. The first ink layer 312 and the second ink layer 313 are both located in the light-blocking area 316, and the second ink layer 313 is arranged around at least part of the edge of the first light-transmitting area 315. The second ink layer 313 covers the edge of the first ink layer 312 close to the first light-transmitting area 315.

[0067] The lens 31 includes a body 311, a first ink layer 312, and a second ink layer 313, wherein the first ink layer 312 and the second ink layer 313 are both located on the body 311. The body 311 has a first light-transmitting area 315 and a light-blocking area 316, and the first ink layer 312 and the second ink layer 313 are both located in the light-blocking area 316. The first ink layer 312 and the second ink layer 313 are both made of opaque ink materials, and therefore, the areas of the first ink layer 312 and the second ink layer 313 corresponding to the body 311 are opaque, and are the light-blocking area 316.

[0068] Exemplarily, the first light-transmitting area 315 may be arranged in a circular shape, and the second ink layer 313 is arranged around at least a portion of the edge of the first light-transmitting area 315 , that is, the second ink layer 313 forms a circle in the middle.

[0069] In some embodiments, an adhesive (not shown) is disposed between the first ink layer 312 and the second ink layer 313. The adhesive is disposed on the surface of the second ink layer 313 so that the second ink layer 313 can be more easily connected to the lens 31 and transferred from the boss 321 to the lens 31, thereby improving the success rate of the transfer.

[0070] In some embodiments, the surface of the lens 31 is moderately oxidized, and a SiO2 film is coated on the surface of the second ink layer 313. The moderately oxidized surface of the lens 31 and the SiO2 film coated on the surface of the second ink layer 313 undergo a condensation reaction to generate Si-O-Si bonds to form chemical bonding, thereby enhancing the adhesion between the lens 31 and the second ink layer 313 and ensuring the success rate of picking up.

[0071] The lens 32 includes a boss 321, which is surrounded by a second light-transmitting area 322, and the second light-transmitting area 322 is arranged opposite to the first light-transmitting area 315. The boss 321 is annular, and the middle of the boss 321 is surrounded by the second light-transmitting area 322. The orthographic projection of the boss 321 on the body 311 coincides with the orthographic projection of the second ink layer 313 on the body 311.

[0072] The second ink layer 313 is formed by applying ink on the boss 321, and transferring the ink to the body 311 through the boss 321. Transfer is a printing technology that transfers the image on the intermediate carrier to the substrate using corresponding pressure. In other words, a certain pressure is applied so that the lower surface of the body 311 contacts the ink, and the ink can be separated from the boss 321 and transferred to the body 311, thereby forming the second ink layer 313.

[0073] The second ink layer 313 covers the edge of the first ink layer 312 on the side close to the first light-transmitting area 315, that is, the second ink layer 313 covers the inner edge of the first ink layer 312. Moreover, the orthographic projection of the inner edge of the first ink layer 312 on the body 311 is located within the orthographic projection area of ​​the second ink layer 313 on the body 311. That is, the second ink layer 313 includes a first portion and a second portion, the second ink layer 313 covers the inner edge of the first ink layer 312, so that the first portion and the first ink layer 312 are overlapped along the Z-axis direction, and the second portion extends from the inner edge of the first ink layer 312 to a direction away from the outer edge of the first ink layer 312, that is, extends to the center close to the first light-transmitting area 315. By covering the inner edge of the first ink layer 312 with the second ink layer 313 to form the first part, the gap between the first ink layer 312 and the second ink layer 313 is avoided to cause a light-transmitting gap, so that the first ink layer 312 and the second ink layer 313 can be seamlessly connected, and the first ink layer 312 and the second ink layer 313 are indistinguishable from each other in the direction from the lens body 311 to the lens 32. The area covered by the ink on the body 311 is enlarged by the second part to form the first light-transmitting area 315. At this time, the second light-transmitting area 322 is arranged opposite to the first light-transmitting area 315, so that the light-transmitting center of the lens 31 coincides with the center of the lens 32, thereby solving the eccentricity problem of the camera module 30 and improving the aesthetics of the camera module 30.

[0074] See also Figure 7 In the camera module 30 of this embodiment, the second ink layer 313 is arranged around at least a portion of the edge of the first light-transmitting area 315, so that the second light-transmitting area 322 is arranged relative to the first light-transmitting area 315, thereby achieving the coincidence of the light-transmitting center of the lens 31 and the center of the lens 32.

[0075] In other embodiments, the outer contours of the second light-transmitting area 322 and the first light-transmitting area 315 may be other shapes, such as square, triangle, pentagon or other polygons, and the present application does not limit the outer contours of the second light-transmitting area 322 and the first light-transmitting area 315. Accordingly, the shape of the second ink layer 313 may be a square frame, a triangle frame, a pentagon frame or other polygonal frame.

[0076] See also Figure 8 In some embodiments, a third ink layer 323 is disposed on the mounting surface 3211 , and an orthographic projection of the third ink layer 323 on the body 311 is located within an orthographic projection region of the second ink layer 313 on the body 311 .

[0077] During the process of transferring the ink to the main body 311, the ink may not be completely transferred to the main body 311, that is, some ink will remain on the mounting surface 3211, and the ink remaining on the mounting surface 3211 is the third ink layer 323. The orthographic projection of the third ink layer 323 on the main body 311 is located within the orthographic projection area of ​​the second ink layer 313 on the main body 311.

[0078] See also Fig. 9 In some embodiments, the boss 321 includes a mounting surface 3211 facing the main body 311, and a first side surface 3212 and a second side surface 3213 respectively connected to the opposite sides of the mounting surface 3211, the orthographic projection of the mounting surface 3211 on the main body 311 coincides with the orthographic projection of the second ink layer 313 on the main body 311, and the first side surface 3212 and the second side surface 3213 are inclined and approach each other in a direction away from the mounting surface 3211.

[0079] The first side surface 3212, the mounting surface 3211, and the second side surface 3213 are connected in sequence, the mounting surface 3211 faces the body 311, and the first side surface 3212 and the second side surface 3213 are respectively connected to two opposite sides of the mounting surface 3211. The orthographic projection of the mounting surface 3211 on the body 311 coincides with the orthographic projection of the second ink layer 313 on the body 311, and the mounting surface 3211 is in a circular shape. The ink is applied to the mounting surface 3211, and then the ink is transferred to the body 311, so that the second ink layer 313 is formed on the body 311.

[0080] The first side surface 3212 and the second side surface 3213 are both arranged at an angle, and the first side surface 3212 and the second side surface 3213 are close to each other in a direction away from the mounting surface 3211. In the case where too much ink is applied on the mounting surface 3211, the excess ink flows downward along the first side surface 3212 or the second side surface 3213 by its own gravity and adheres to the first side surface 3212 or the second side surface 3213 to achieve visual concealment. By arranging the first side surface 3212 and the second side surface 3213 at an angle, compared with the first side surface 3212 and the second side surface 3213 extending directly in a direction perpendicular to the mounting surface 3211, the area will be larger, more ink can be hidden, and the second light-transmitting area 322 will not be reduced.

[0081] In some embodiments, the lens 32 further includes a main body 328, which is connected to the boss 321. The first side 3212 and the second side 3213 can be planes to facilitate the downward flow of ink. The first side 3212 and the second side 3213 can also be curved surfaces, such as cambered surfaces, to further increase the area of ​​the first side 3212 and the second side 3213, so that more ink can be hidden. The first side 3212 and the second side 3213 can be symmetrically arranged, so that the structure of the boss 321 is more stable and the force is more uniform. When too much ink is applied to the mounting surface 3211, the flow rate of the excess ink on the first side 3212 and the second side 3213 can be kept consistent. The first side 3212 and the second side 3213 can also be asymmetrically arranged, and adjusted according to the amount of ink so that the areas of the first side 3212 and the second side 3213 are different.

[0082] In some embodiments, the first side surface 3212 and the second side surface 3213 are both planes, and the first side surface 3212 and the second side surface 3213 are symmetrically arranged, and the angle between the first side surface 3212 and the mounting surface 3211 is A, A is an acute angle, and A can be 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70° or 80°. In the case of 30°≤A≤70°, the contact area between the boss 321 and the main body 328 of the lens 32 is moderate, and a certain connection strength can be achieved between the boss 321 and the main body 328. The smaller A is, the larger the area of ​​the first side surface 3212 and the second side surface 3213 is, and more area for hiding ink can be provided. The larger A is, the larger the contact area between the boss 321 and the main body 328 is, and the stronger the connection strength between the boss 321 and the main body 328 is.

[0083] See also Fig.10 The mounting surface 3211 is in a circular shape. Ink is applied to the mounting surface 3211 , and then the ink is transferred to the body 311 , so that a second ink layer 313 is formed on the body 311 .

[0084] See also Fig.11 As shown in (a), (b) and (c) of the drawings, in some embodiments, a deinking layer 324 is provided on the mounting surface 3211, and the deinking layer 324 includes a plurality of deinking structures 3241, wherein the cross-sectional area of ​​each deinking structure 3241 on the side away from the boss 321 is smaller than the cross-sectional area on the side close to the boss 321.

[0085] The deinking layer 324 is disposed on the mounting surface 3211, and the deinking layer 324 and the mounting surface 3211 can be connected by gluing. The deinking layer 324 includes a plurality of deinking structures 3241, and the plurality of deinking structures 3241 are disposed at intervals or adjacent to each other. The cross-sectional area of ​​each deinking structure 3241 on the side away from the boss 321 is smaller than the cross-sectional area on the side close to the boss 321. The ink contacts the upper end of the deinking structure 3241, and the cross-sectional area of ​​the deinking structure 3241 on the side away from the boss 321 is smaller than the cross-sectional area on the side close to the boss 321, thereby reducing the contact area between the deinking layer 324 and the ink, so that the ink can be more easily separated from the mounting surface 3211 and transferred to the lens 31, thereby improving the success rate of the transfer.

[0086] See also Fig.11 In (a), in some embodiments, the deinking structure 3241 is tilted, and the angle between the deinking structure 3241 and the mounting surface 3211 is B, which is an acute angle, and B can be 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70° or 80°. The deinking structure 3241 is a gecko-like tilted bristle, and the tilted bristle of the gecko has the characteristics of strong adhesion, easy debonding, reusability, and strong adaptability to the substrate. The larger the tilt angle of the tilted bristle, the smaller the rigidity, and the softer the contact between the tilted bristle and the contact surface. Under the action of external forces of the same magnitude, more tilted bristles can be brought into contact with the contact surface, and the tilted bristles show stronger adaptability.

[0087] In some embodiments, the de-inking structure 3241 is made of an elastically restorable material. During transfer, a certain pressure needs to be applied to the lens 31 so that the body 311 of the lens 31 is in full contact with the second ink layer 313 on the boss 321. The de-inking structure 3241 is made of an elastically restorable material. When the lens 31 is pressed downward, pressure is applied to the de-inking structure 3241 so that the de-inking structure 3241 is deformed. When the lens 31 moves upward, the de-inking structure 3241 has an elastic force to restore upward, so that the second ink layer 313 is easier to separate from the mounting surface 3211 and transfer to the lens 31, thereby improving the success rate of transfer.

[0088] See also Fig.11 In (b) and (c) of the figure, in some embodiments, the deinking structure 3241 can be in a pyramid-like shape, or a hemispherical shape, so that the cross-sectional area of ​​the deinking structure 3241 gradually decreases from the side close to the boss 321 to the side away from the boss 321, thereby achieving structural stability and uniform force on the deinking structure 3241.

[0089] See also Fig.12In some embodiments, the camera module 30 further includes a bracket 33, which is formed with a through hole 331 and a protrusion 332 located on the wall of the through hole 331, and the protrusion 332 divides the through hole 331 into a first connecting section 3311 and a second connecting section 3312 that are connected.

[0090] The bracket 33 is formed with a through hole 331, which penetrates the bracket 33 along the Z-axis direction. The protrusion 332 is located on the hole wall of the through hole 331, and the protrusion 332 divides the through hole 331 into a first connecting section 3311 and a second connecting section 3312 which are connected. The first connecting section 3311 and the second connecting section 3312 are distributed along the Z-axis direction.

[0091] See also Fig.13 By setting the first connecting section 3311 to mount the lens 31 and setting the second connecting section 3312 to mount the lens 32, the bracket 33 can fix the relative position of the lens 32 and the lens 31. Figure 4 The solution of fixing the lens 32 by the first fixing frame 36, fixing the lens 31 by the second fixing frame 37, and then realizing the positioning connection between the first fixing frame 36 and the second fixing frame 37 by the positioning column 362 can reduce the material tolerance and assembly tolerance, shorten the tolerance chain, and reduce the deviation between the lens 31 and the lens 32. In addition, by setting a bracket 33, the relative position of the lens 32 and the lens 31 can be fixed, which can reduce the process steps and assembly steps, improve work efficiency, and save costs.

[0092] In some embodiments, the hole wall of the first connecting section 3311 and the protrusion 332 together form a first step surface 333, and the first step surface 333 includes a first surface 3331 and a second surface 3332. The first surface 3331 extends along the direction of the plane where the X-axis and the Y-axis are located, and the second surface 3332 extends along the Z-axis direction. The first ink layer 312 is connected to the first surface 3331, and the first surface 3331 supports the lens 31. The side of the body 311 is connected to the second surface 3332. By setting the second surface 3332 and the first surface 3331 to cooperate, the body 311 is limited in the direction where the X-axis and the Y-axis are located, so that the position of the lens 31 is fixed.

[0093] The lens 32 is at least partially installed in the second connecting section 3312. The hole wall of the second connecting section 3312 limits the direction of the lens 32 in the plane where the X-axis and the Y-axis are located, so that the position of the lens 32 and the lens 31 is relatively fixed, which facilitates the accurate transfer of ink to the main body 311, so that the orthographic projection of the second light-transmitting area 322 on the main body 311 coincides with the first light-transmitting area 315.

[0094] The hole wall of the second connecting section 3312 and the protrusion 332 together form a second step surface 334. The lens 32 also includes a main body 328 connected to the boss 321. The main body 328 forms a third step surface 326. The second step surface 334 and the third step surface 326 abut against each other.

[0095] The main body 328 is connected to the end of the boss 321 away from the lens 31, and a third step surface 326 is formed on the main body 328. A second step surface 334 is formed on the second connecting section 3312, and the second step surface 334 matches the shape of the third step surface 326. The second step surface 334 and the third step surface 326 abut against each other, and the second step surface 334 and the third step surface 326 cooperate with each other to achieve the limitation of the main body 328 in the X-axis and Z-axis directions. Specifically, the second step surface 334 and the third step surface 326 both have a third surface extending along the plane where the X-axis and the Y-axis are located and a fourth surface extending along the Z-axis direction. The third surfaces of the second step surface 334 and the third step surface 326 cooperate with each other to limit the main body 328 in the Z-axis direction to prevent the main body 328 from shaking in the Z-axis direction. The fourth surfaces of the second step surface 334 and the third step surface 326 cooperate with each other to limit the main body 328 in the direction of the plane where the X-axis and the Y-axis are located.

[0096] See also Fig.13 In some embodiments, the camera module 30 further includes a bonding structure 34 , and the bonding structure 34 is located between the protrusion 332 and the lens 31 .

[0097] One side of the adhesive structure 34 is connected to the lens 31, and the other side of the adhesive structure 34 is connected to the protrusion 332. The lens 31 is connected to the bracket 33 by setting the adhesive structure 34. In some embodiments of the present application, the adhesive structure 34 is a double-sided tape, and the adhesive structure 34 is respectively bonded to the protrusion 332 and the lens 31. In this way, by setting the adhesive structure 34 as a double-sided tape, it is helpful to simplify the connection process between the adhesive structure 34 and the protrusion 332 and between the adhesive structure 34 and the lens 31, thereby reducing costs.

[0098] See also Fig.13 In some embodiments, the adhesive structure 34 includes a compressible layer 341 and an adhesive layer 342. The adhesive layer 342 is located between the compressible layer 341 and the lens 31, and is adhered to the compressible layer 341 and the lens 31 respectively.

[0099] The pasting structure 34 is pasted to the lens 31 by providing a pasting layer 342. In addition, the pasting structure 34 also includes a compressible layer 341, which can be compressed and restored. The compressible layer 341 can push the lens 31 to move upward, thereby improving the efficiency of transfer.

[0100] In some embodiments, the adhesive structure 34 can be a foam double-sided adhesive. The foam double-sided adhesive refers to a double-sided adhesive formed by coating adhesive on both sides of a foam cotton substrate and then covering one side with release paper or release film. The foam cotton substrate in the foam double-sided adhesive can be compressed to form a compressible layer 341. Adhesive is coated on both sides of the foam cotton substrate, and one side of the foam double-sided adhesive is covered with release paper or release film. The release paper or release film mainly serves to isolate sticky objects and facilitate the installation of the foam double-sided adhesive. The foam double-sided adhesive has the characteristics of strong adhesion, good retention, good waterproof performance, and strong temperature resistance.

[0101] In some other embodiments, the adhesive structure 34 may be formed by applying glue on both sides of a compressible material, and the compressible material forms a compressible layer 341 . The compressible material may be foam, sponge, polymer foam material or other compressible material.

[0102] In some embodiments, the dimension of the adhesive structure 34 along the Z-axis direction is X, 0.1 mm ≤ X ≤ 0.3 mm, and X can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm or 0.3 mm. The adhesive structure 34 has a certain thickness, and the restoring force generated by the compression of the compressible layer 341 can push the lens 31 to move upward, and does not occupy too much space.

[0103] See also Fig.14 In some embodiments, for the rear camera, there may be multiple lenses 32, and the multiple lenses 32 are arranged at intervals. The bracket 33 has multiple through holes 331, and the multiple through holes 331 are arranged at intervals. The number of through holes 331 is consistent with that of the lenses 32 and they are arranged one by one. Each through hole 331 is used to install a lens 32. Fig.14 , Fig.14 The number of the middle lens 32 is four, and the four lenses 32 are arranged at intervals. Fig.15 , Fig.15 The number of the middle lenses 32 is three, and the three lenses 32 are arranged at intervals.

[0104] See also Fig.16 , there are multiple through holes 331, multiple through holes 331 are arranged at intervals, there are multiple lenses 32, and the number of through holes 331 and lenses 32 are consistent and arranged one by one. A protrusion 332 is provided on the hole wall of each through hole 331, and the protrusion 332 divides the corresponding through hole 331 into a first connecting section 3311 and a second connecting section 3312 that are connected, so that one bracket 33 can fix multiple lenses 32. When the number of lenses 31 is one, multiple first connecting sections 3311 are connected to each other, and multiple second connecting sections 3312 are separated from each other. The lens 31 is installed in the first connecting section 3311. After one transfer, the eccentricity problem of multiple lenses 32 can be improved at the same time, thereby improving work efficiency.

[0105] When there are multiple lenses 31 , the number of lenses 31 and the number of through holes 331 are consistent and arranged in one-to-one correspondence, and the lenses 31 are installed in the corresponding first connecting sections 3311 .

[0106] See also Fig.17 In some embodiments, a first magnet 325 is disposed in the boss 321 , and a second magnet 314 is disposed in the second ink layer 313 . The first magnet 325 and the second magnet 314 have the same polarity.

[0107] The first magnet 325 is disposed in the boss 321, and the second magnet 314 is disposed in the second ink layer 313. The second magnet 314 can be added in the second ink layer 313 in the form of particles. The first magnet 325 and the second magnet 314 have the same polarity, so that the first magnet 325 and the second magnet 314 repel each other. The mutual repulsive force of the first magnet 325 and the second magnet 314 makes it easier for the second ink layer 313 to be separated from the boss 321 and transferred to the lens 31, thereby improving the success rate of transfer.

[0108] See also Fig.18 In some embodiments, a first magnet 325 is disposed in the boss 321 , and a third magnet 35 is disposed on a side of the lens 31 away from the lens 32 . The first magnet 325 and the third magnet 35 have the same polarity.

[0109] By arranging the third magnet 35 on the side of the lens 31 away from the lens 32, the first magnet 325 and the third magnet 35 have the same polarity, so that the first magnet 325 and the third magnet 35 repel each other, and the mutual repulsion force between the first magnet 325 and the third magnet 35 makes it easier for the second ink layer 313 to detach from the boss 321 and transfer to the lens 31, thereby improving the success rate of transfer. Compared with the method of arranging the second magnet 314 in the second ink layer 313, arranging the third magnet 35 on the side of the lens 31 away from the lens 32 does not change the structure of the second ink layer 313, ensuring that the second ink layer 313 and the first ink layer 312 have the same structure, and achieving no difference between the first ink layer 312 and the second ink layer 313 in the direction from the lens 31 body 311 to the lens 32.

[0110] In addition, the present application embodiment provides a method for manufacturing a camera module 30, please refer to Fig.19 Figures (a), (b), (c) and (d) in Fig.19 This is a flowchart of a method for manufacturing a camera module according to some embodiments of the present application.

[0111] The method for manufacturing the camera module 30 includes steps S10 to S40.

[0112] Step S10 , providing a lens 32 , wherein the lens 32 includes a boss 321 .

[0113] See also Fig.19 In FIG. 8( a ), the boss 321 is located at the upper end of the lens 32 .

[0114] In step S20 , ink is applied to the boss 321 to form an ink layer 327 to be transferred on the boss 321 .

[0115] See also Fig.19 In FIG. (b), the lens 32 includes a boss 321, and the cross section of the boss 321 is annular. The middle of the boss 321 forms a second light-transmitting area 322. Ink is applied to the upper surface of the boss 321, and specifically, the ink is a delayed curing ink, so that an ink layer 327 to be transferred is formed on the upper surface of the boss 321, and the ink layer 327 to be transferred is annular.

[0116] Step S30 , providing a lens 31 , the lens 31 comprises a body 311 and a first ink layer 312 located on the body 311 , the body 311 has an initial light-transmitting area 317 and an initial light-blocking area 318 , and the first ink layer 312 is located in the initial light-blocking area 318 .

[0117] See also Fig.19 In Figure (c), the lens 31 includes a body 311 and a first ink layer 312. The first ink layer 312 is located on the body 311. The first ink layer 312 and the second ink layer 313 can be the same ink or different inks. Regardless of whether the first ink layer 312 and the second ink layer 313 are the same ink, they need to be opaque ink. The body 311 has an initial light-transmitting area 317 and an initial light-blocking area 318. The first ink layer 312 is an opaque ink. Therefore, the area of ​​the first ink layer 312 corresponding to the body 311 is opaque, which is the initial light-blocking area 318. The area on the body 311 where the first ink layer 312 is not provided can be light-transmitting, which is the initial light-transmitting area 317.

[0118] The edge of the first ink layer 312 close to the initial light-transmitting area 317 is the inner edge, and the edge of the first ink layer 312 away from the initial light-transmitting area 317 is the outer edge. The lens 31 and the lens 32 are aligned, and the lens 31 is moved so that the lens 31 and the lens 32 are arranged opposite to each other, and the orthographic projection of the inner edge of the first ink layer 312 on the body 311 is located within the orthographic projection area of ​​the second ink layer 313 on the body 311. At this time, the orthographic projection of the outer contour of the initial light-transmitting area 317 and the second light-transmitting area 322 of the lens 32 on the lens 31 partially overlap, and the center of the initial light-transmitting area 317 is eccentric to the center of the second light-transmitting area 322. In addition, the orthographic projection of the outer contour of the second light-transmitting area 322 on the lens 31 is located within the initial light-transmitting area 317, that is, the area of ​​the initial light-transmitting area 317 is larger than the area of ​​the orthographic projection of the outer contour of the second light-transmitting area 322 on the lens 31.

[0119] In step S40, at least a portion of the ink layer 327 to be transferred is transferred to the main body 311 to form a second ink layer 313 on the lens 31, shrinking the initial light-transmitting area 317 and forming a first light-transmitting area 315; the second ink layer 313 covers the edge of the first ink layer 312 close to the initial light-transmitting area 317.

[0120] See also Fig.19 As shown in Figure (d), transfer printing is a printing technology that transfers the image and text on the intermediate carrier to the substrate by using corresponding pressure. That is, a certain pressure is applied so that the surface of the body 311 close to the boss 321 contacts the transfer ink layer, and at least part of the transfer ink layer can be separated from the boss 321 and transferred to the body 311, thereby forming a second ink layer 313 on the lens 31.

[0121] In some embodiments, the orthographic projection of the inner edge of the first ink layer 312 on the body 311 is located within the orthographic projection area of ​​the second ink layer 313 on the body 311, and the initial light-transmitting area 317 partially overlaps with the orthographic projection of the outer contour of the second light-transmitting area 322 of the lens 32 on the lens 31. The lens 31 is moved toward the direction close to the lens 32, so that the lens 31 contacts the ink layer 327 to be transferred on the boss 321, and pressure is applied to the lens 31 and kept for a certain period of time, and the lens 31 is moved away from the lens 32, so that the ink layer 327 to be transferred is separated from the boss 321 and transferred to the lens 31, and the second ink layer 313 is formed on the lens 31, thereby completing the transfer.

[0122] The ink layer 327 to be transferred is transferred onto the body 311, so that a second ink layer 313 is formed on the lens 31, and the second ink layer 313 covers the inner edge of the first ink layer 312. That is, the second ink layer 313 includes a first portion and a second portion, and the second ink layer 313 covers the inner edge of the first ink layer 312, so that the first portion and the first ink layer 312 are overlapped along the Z-axis direction, and the second portion extends from the inner edge of the first ink layer 312 in a direction away from the outer edge of the first ink layer 312, that is, extends toward the center of the first light-transmitting area 315. By covering the inner edge of the first ink layer 312 with the second ink layer 313 to form the first portion, a light-transmitting gap caused by the interval between the first ink layer 312 and the second ink layer 313 is avoided, so that the first ink layer 312 and the second ink layer 313 can be seamlessly connected, and there is no difference between the first ink layer 312 and the second ink layer 313 in the direction from the body 311 of the lens 31 to the lens 32. The initial light blocking area 318 is enlarged by the second part, and the initial light transmitting area 317 is reduced to form the first light transmitting area 315. At this time, the second light transmitting area 322 is arranged relative to the first light transmitting area 315 and the centers coincide with each other, so that the light transmitting center of the lens 31 coincides with the center of the lens 32, thereby solving the eccentricity problem of the camera module 30 and improving the aesthetics of the camera module 30.

[0123] After the transfer ink layer 327 is transferred to the body 311, the second ink layer 313 can be cured. By curing the second ink layer 313, the second ink layer 313 can be more stably and firmly located on the body 311, avoiding the displacement of the uncured second ink layer 313 on the body 311. Specifically, the second ink layer 313 can be cured by heating or ultraviolet light.

[0124] In some embodiments, see Fig. 20 In (a) and (b) of the drawings, the camera module 30 further comprises a bracket 33, the bracket 33 is formed with a through hole 331, and a protrusion 332 located on the hole wall of the through hole 331, the protrusion 332 divides the through hole 331 into a first connecting section 3311 and a second connecting section 3312 which are connected. By setting the first connecting section 3311 to mount the lens 31, and setting the second connecting section 3312 to mount the lens 32, the bracket 33 can fix the relative position of the lens 32 and the lens 31.

[0125] The camera module 30 further includes an adhesive structure 34, which is located between the protrusion 332 and the lens 31. The adhesive structure 34 is attached to the lens 31 by providing an adhesive layer 342. In addition, the adhesive structure 34 further includes a compressible layer 341, which can be compressed and restored. The compressible layer 341 can push the lens 31 to move upward, thereby improving the efficiency of transfer.

[0126] See also Fig. 20 As shown in FIG. (a), the protrusion 332 of the adhesive structure 34 is connected, thereby fixing the adhesive structure 34, so that the adhesive structure 34 is stably and reliably mounted on the bracket 33. The lens 31 is pressed toward the direction close to the lens 32, so that the lens 31 contacts the adhesive layer 342 of the adhesive structure 34, and the lens 31 and the adhesive structure 34 are bonded. Then, the lens 31 is pressed toward the direction close to the lens 32, so that the compressible layer 341 is compressed, and the first ink layer 312 on the lens 31 contacts the ink layer 327 to be transferred on the protrusion 321, and the ink layer 327 to be transferred is transferred to the lens 31.

[0127] See also Fig. 20 In (b), the lens 31 is released, the compressible layer 341 is restored, and the lens 31 is pushed upward, so that the lens 31 is out of contact with the boss 321, and the transfer of the ink layer 327 to be transferred is completed to form the second ink layer 313. The compressible layer 341 is provided in the adhesive structure 34, and the compressible layer 341 can push the lens 31 to move upward, thereby improving the efficiency of the transfer.
