[0002] This application claims priority to Chinese Patent Application No. 202010651516.8, filed on July 8, 2020, entitled "Prism Assembly, Periscope Camera Module and Method for Assembling Prism Assembly", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of camera module technology, and more specifically, to a prism assembly that fixes a prism and a lens together, a corresponding periscope camera module, and a corresponding assembly method. Background Technology

[0004] As living standards rise, consumers have increasingly higher demands for the camera functions of mobile phones, tablets, and other terminal devices. They not only require effects such as background blur and night shooting, but also demand telephoto capabilities, needing devices that can clearly capture distant scenes. To capture distant scenes, a longer focal length is typically needed for the camera module. For vertical modules, increasing the focal length inevitably increases height; however, due to the size limitations of terminal devices (such as mobile phones), especially the thickness, vertical telephoto modules can only achieve an equivalent focal length of 2x-3x compared to the main camera. Periscope camera modules, on the other hand, offer a higher magnification focal length than the main camera, therefore, periscope camera modules are typically used for long-distance or ultra-long-distance shooting. Periscopes use prisms to fold the light path, changing the module's height from along the incident direction to perpendicular to it, thus avoiding an increase in the thickness of the phone (or other terminal device) due to the increased magnification. Currently, periscope camera modules in mobile phones can achieve an equivalent focal length of 5x-10x compared to main camera / wide-angle modules. Therefore, periscope camera modules are the best choice for mobile phone manufacturers to achieve telephoto capabilities without increasing the thickness of the phone.

[0005] Periscope modules typically include prisms and multiple lenses. The prisms have the ability to fold light, and the light reflected from the prisms needs to pass through each lens as stably as possible to form a relatively clear image on the chip. In addition, due to the long focal length and the large proportion of the subject in the frame, periscope modules are often equipped with an OIS mechanism to reduce the impact of image shake, enabling the periscope module to achieve image stabilization.

[0006] In existing technologies, for schemes where a lens is placed at the front end of a prism (the end closest to the object), the lens and prism are usually assembled into a single module. However, lenses are often circular, while the facets of a prism are generally polygonal; their shapes are not identical, which increases the difficulty of assembly. Since a camera module is a high-precision optical system, even a slight misalignment of the optical components can cause a decrease in image quality or even prevent imaging. Therefore, achieving high-precision assembly of the prism and lens to obtain a prism assembly and camera module with better production yield and consistency is crucial.

[0007] Therefore, there is a current need for a new solution for the assembly structure and method of prisms and lenses in order to improve the production yield and consistency of prism components and periscope camera modules. Summary of the Invention

[0061] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0062] Figure 1 A perspective view of a periscope camera module according to one embodiment of this application is shown. (Reference) Figure 1 In this embodiment, the periscope optical lens includes a prism assembly 100, a second lens assembly 200, and a photosensitive assembly 300. The prism assembly 100 includes a first lens group, a reflecting prism, and a composite lens barrel 103 for assembling the first lens group and the reflecting prism. Figure 1 The drawing actually only shows the compound lens tube 103 and the first lens group 102. The reflecting prism is located below the first lens group 102. For the sake of simplicity, the drawing is omitted. Figure 1 The reflecting prism is not directly shown. Additionally, the first lens group 102 may include one or more first lenses and other auxiliary optical elements (such as light-blocking plates or spacers). For clarity, Figure 1 The first lens group 102 is represented only by the first lens. Furthermore, Figure 2a A schematic diagram of the optical path of the first lens group and the reflecting prism in one embodiment of this application is shown. (Reference) Figure 2a The first lens group 102 includes at least one lens located at the incident end of the reflecting prism 101. In this embodiment, the top surface 101a of the reflecting prism 101 is the incident surface, and the first lens group 102 is located at the top of the reflecting prism 101. In this embodiment, the first lens group 102 has positive refractive power, which can converge the light from the object before it enters the top surface 101a of the prism 101. This design can reduce the area of ​​the incident surface of the prism 101, thereby ensuring that the size of the prism is basically no more than the size of the first lens group (or in other words, the size of the top surface of the prism is no more than the size of the largest lens in the first lens group). Here, the size of the prism and the lens refer to the size from a top-down angle. Generally speaking, the lens is circular, and its size is its diameter. The surface of the prism is square (or rectangular), and its size can be the length of its diagonal. By setting the first lens group with positive refractive power at the front end of the reflecting prism 101, the aperture of the imaging channel can be reduced, thereby reducing the area of ​​the incident surface, reflecting surface, and emitting surface of the prism 101 located at its rear end. Because the aperture of the imaging channel required inside prism 101 is reduced, the height of the periscope camera module (the dimension in the direction of light incidence, i.e., the dimension in the direction normal to the prism's incident surface) can be reduced by designing a smaller prism. Conversely, in contrast, Figure 2b A schematic diagram of the optical path of the first lens group and the reflecting prism is shown, where the first lens has negative refractive power. It can be seen that... Figure 2b In the comparative example shown, because the first lens group has negative refractive power, the aperture of the imaging channel is enlarged. Therefore, prism 101 needs to provide an imaging channel with a larger aperture, thus requiring prism 101 to have a larger volume, which is detrimental to reducing the height and volume of the periscope camera module. Further, still referring to... Figure 1In this embodiment, a second lens group 202 is provided at the exit end of the prism (i.e., the rear end of the prism). The second lens group 202 can be installed in the second lens barrel 201 to form the second lens assembly 200. In this embodiment, since the prism optical path is folded, the height of the periscope camera module (or periscope optical lens) is not determined by the length of the optical path. At this time, by controlling the aperture of each lens in the second lens group, the height of the periscope camera module can be maintained without increasing it. For example, the maximum height of the second lens assembly 200 is denoted as L2, and the height of the prism assembly 100 is denoted as L1, so that L2≤L1. In actual design, as long as the diameter of the lens with the largest aperture in the second lens group and the wall thickness of the corresponding section of the second lens barrel are controlled, L2≤L1 can be ensured. In the above embodiment, by using a lens group with positive refractive power at the front end of the prism, the height of the prism can be reduced by about 2-3mm, thereby reducing the height of the periscope module. Furthermore, in this embodiment, the photosensitive component 300 is located at the rear end of the second lens assembly 200. The photosensitive component 300 includes a photosensitive chip, which is used to receive light passing through the optical lens and output image data after imaging.

[0063] Furthermore, Figure 3 A perspective view of a prism assembly according to one embodiment of this application is shown. (Reference) Figure 3 In this embodiment, the prism assembly 100 has a component for assembling the first lens group 102 and the reflecting prism 101 (see reference). Figure 2a The composite lens barrel 103 is used in a camera module. In a camera module, multiple optical elements need to be assembled according to their positional relationships determined by their optical design to achieve the desired imaging quality and camera function. Typical vertical camera modules use a cylindrical lens barrel to assemble multiple lenses together. However, for periscope modules, the addition of a prism as a special optical element increases the assembly difficulty. In some existing solutions, a separate housing is fabricated for the prism as a structural component, and then this housing is assembled with the lens barrel. In this embodiment, both the incident and emitting sides of the prism have lenses. If the prism, the incident lens group (i.e., the first lens group), and the emitting lens group (i.e., the second lens group) are each fabricated independently, it may result in too many structural components. Furthermore, assembling multiple structural components together can easily introduce larger tolerances during the assembly process. This accumulation of assembly tolerances may lead to a decrease in the consistency of the periscope lens or module finished product and may also lead to a reduction in production yield. This embodiment provides a composite lens barrel for assembling the first lens group and the reflecting prism together. Figure 4 A longitudinal sectional perspective view of a composite lens barrel according to one embodiment of this application is shown. (Referring to reference...) Figure 3 and Figure 4In this embodiment, the composite lens barrel 103 is generally rectangular and has a composite mounting hole 106 inside. The composite mounting hole 106 has an upper segment 106a and a lower segment 106b. Figure 4 The first depth D1 indicates the depth of the upper segment 106a, and the second depth D2 indicates the depth of the lower segment 106b. That is, in the composite mounting hole 106, the segment corresponding to the first depth D1 is the upper segment 106a, and the segment corresponding to the second depth D2 is the lower segment 106b. Further, the upper segment 106a of the composite mounting hole 106 is used to support and fix the first lens group 102. The lower segment 106b of the composite mounting hole 106 is used to support and fix the prism 101 (refer to reference). Figure 2a Specifically, the upper segment 106a has steps for mounting the individual lenses of the first lens group 102. The steps may include a horizontal step surface and a vertical surface. When the first lens group 102 includes multiple lenses, the upper segment 106a may have multiple steps. Figure 5 A longitudinal sectional perspective view of a composite lens barrel with multi-steps according to an embodiment of this application is shown. (Reference) Figure 5 In this embodiment, the upper segment 106a of the composite lens barrel 106 has multiple steps, each step including a step surface and a vertical surface. For example, the first step may have a first step surface 107b and a first vertical surface 107a, the second step may have a second step surface 108b and a second vertical surface 108a, and the third step may have a third step surface 109b and a third vertical surface 109a. Still referring to... Figure 3 From a top view, the upper segment 106a may include a first mounting groove 104 and a second mounting groove 105. The second mounting groove 105 is similar to the mounting groove on the inner side of a typical circular lens barrel, and its shape can be a roughly circular through-hole. The first mounting groove 104 is a clearance groove, which is disposed through the four corners of the circular through-hole of the second mounting groove 105, allowing the top surface of the square (or rectangular) prism 101 to pass through the upper segment 106a and enter the lower segment 106b. It should be noted that since the first mounting groove 104 is through-hole, it may not have a step (i.e., the first mounting groove 104 may not have a stepped surface). Further, in this embodiment, the first mounting groove 104 is approximately right-angled from a top view, and this right angle can fit with the four corners of the top surface of the prism 101. The depth of the first mounting groove 104 is 1-1.6 mm. In one embodiment, the depth of the first mounting groove is preferably 1.3 mm to ensure that two lenses can be disposed at the front end of the prism. The depth of the first mounting groove 104 refers to the distance from the upper surface of the compound lens barrel 103 to the interface between the upper segment 106a and the lower segment 106b. The interface between the upper segment 106a and the lower segment 106b can be a stepped surface used to support the bottommost first lens (e.g., Figure 5The third step surface 109b in the middle). In other embodiments, the interface between the upper segment 106a and the lower segment 106b may also be lower than the step surface of the bottom first lens, for example, the position of the top surface of the prism can be regarded as the interface. Further, in order to ensure that the prism is not easily interfered with when assembled into the lens barrel, in one embodiment, the distance between the sidewall of the first mounting groove and the edge of the top surface of the prism is at least 3 μm (that is, at the position of any protrusion, there is a gap of at least 3 μm between the sidewall of the first mounting groove and the edge of the top surface of the prism). In other words, the side length of the rectangular profile formed by the first mounting groove is at least 6 μm longer than the corresponding side of the top surface of the prism (each side of the rectangular profile formed by the first mounting groove corresponds to two protrusions, and at the position of each protrusion, the distance between the sidewall of the first mounting groove and the edge of the top surface of the prism is at least 3 μm, so the side length of the rectangular profile is at least 6 μm longer than the corresponding side of the top surface of the prism). In this embodiment, to prevent the lens size of the first lens group from increasing further, the outer diameter of the lens is chosen to interfere with the rectangular mounting hole of the prism, thus eliminating the need to enlarge the outer diameter of the lens to allow the prism to pass through. This further controls the size of the lens.

[0064] In the above embodiments, the prism can be a triangular prism with two right-angled faces and an inclined plane, or it can be a deformed triangular prism formed by cutting off the corner portion of the prism. Generally, the two right-angled faces are perpendicular to each other, serving as the incident and exiting surfaces respectively, and the inclined plane can serve as the reflecting surface.

[0065] Furthermore, in one embodiment of this application, the first lens group may include a light-shielding sheet (e.g., SOMA) or a spacer. Figure 6a A top view schematic diagram of a light-shielding sheet or spacer in one embodiment of this application is shown. Figure 6b A perspective view of a light-shielding sheet or spacer according to one embodiment of this application is shown. (Reference) Figure 6a and Figure 6bIn this embodiment, the top view shape of the light-shielding plate or spacer is an annular shape with four protrusions. The outer contours of the four protrusions form a rectangle that matches the top surface shape of the prism. The shape of the through-hole formed by the contours of the four first mounting slots is adapted to the shape of the through-hole. In this way, the four protrusions can be positioned in the positions of the four first mounting slots. This design can prevent glue leakage during the dispensing step of the assembly process. Specifically, due to the SOMA with protrusions, glue will not leak directly from the first mounting slots to the lower part (e.g., from the upper segment to the lower segment of the composite through-hole) during the dispensing step, thereby avoiding stains or other problems on the prism surface. It should be noted that in this application, the shape of the light-shielding plate and spacer matches the top view contour of the upper segment of the composite lens barrel. The top view contour of the upper segment is actually a composite shape formed by the fusion of the first mounting slot and the second mounting slot. Specifically, this composite shape is a shape formed by partial outward protrusion of a circle. Therefore, this composite shape is sometimes referred to as a circle with protrusions in this document. In this embodiment, since the top surface of the prism is rectangular, the composite shape includes four protrusions, each with a right angle, and the four protrusions can form a discontinuous rectangular outline so that the top surface of the prism can pass through. It should be noted that the top surface of the prism in this application is not limited to a rectangle. For example, in other embodiments of this application, the top surface of the prism can be a deformed rectangle, such as a polygon formed by cutting off the four corner sections of a rectangle, or a rounded rectangle formed by chamfering a rectangle. In this case, the top view profile of the upper segment of the composite lens tube can also be adjusted accordingly. Simultaneously, the top view profile of the light-shielding plate or spacer can also be adjusted accordingly; that is, the top view profile of the light-shielding plate or spacer can be a composite shape matching the shape of the upper segment (e.g., a circle with protrusions).

[0066] Furthermore, in one embodiment of this application, the first lens group includes at least one irregularly shaped first lens. Figure 7 A top view schematic diagram of an irregularly shaped first lens according to one embodiment of this application is shown. (Reference) Figure 7In this embodiment, the top view of the irregularly shaped first lens is generally an annular shape with four protrusions. These four protrusions form four right angles, and the outer contours of the four protrusions can generally form a rectangle. This rectangle can be adapted to the shape of the top surface of the prism, that is, to the shape of the through square clearance hole formed by the contours of the four first mounting slots. In this way, the four protrusions can be positioned in the positions of the four first mounting slots. This irregularly shaped first lens design can also prevent glue leakage during the dispensing step of the assembly process. That is, due to the first lens with protrusions, during the dispensing step, glue will not directly leak from the first mounting slots to the bottom (e.g., from the upper segment to the lower segment of the composite through hole), thereby avoiding stains or other problems on the prism surface. It should be noted that the top surface of the prism described in this application is not limited to a rectangle. For example, in other embodiments of this application, the top surface of the prism can be a deformed rectangle, such as a polygon formed by cutting off the four corner sections of a rectangle, or a rounded rectangle formed by chamfering a rectangle. At this time, the top view profile of the upper segment of the composite lens barrel can also be adjusted accordingly. Simultaneously, the top view profile of the irregularly shaped first lens can also be adjusted accordingly; that is, the top view profile of the irregularly shaped first lens can be a composite shape (e.g., a circle with protrusions) that matches the shape of the upper segment.

[0067] Furthermore, in one embodiment of this application, in the prism assembly, the longitudinal section of the first mounting groove of the composite lens tube has an inclined edge. Figure 8 A cross-sectional schematic diagram of a composite lens barrel and a prism to be assembled according to one embodiment of this application is shown. (Reference) Figure 8 In this embodiment, the tilt angle of the inclined edge C is 30-45°. The tilt angle of the inclined edge C refers to the angle between the inclined edge and the vertical direction. In this embodiment, the inclined edge can be used to guide the prism during assembly, improving the prism's assemblability. Specifically, during assembly, when the prism passes through the upper segment, even if it encounters the inclined edge (or inclined surface) causing interference between the prism and the lens barrel, it will guide the prism to move obliquely downwards or form a downward movement tendency, thus facilitating assembly. Furthermore, the inclined edge design also helps improve the demolding ability of the composite lens barrel. Specifically, the composite lens barrel can be manufactured using plastic molding processes such as molding or injection molding. When the top of the composite lens barrel has an inclined edge, it can help demold the molded lens barrel, avoiding rough demolding surfaces caused by poor demolding.

[0068] Further, in one embodiment of this application, the second mounting groove of the composite lens barrel of the prism assembly has three steps. The first step, located near the object side, is used to mount a light-shielding element; the second step is used to mount a first first lens; and the third step is used to mount a second first lens. A spacer (or SOMA) may be present between the first and second first lenses to prevent stray light generated by the first first lens from passing through the second first lens. In this embodiment, the first lens can be understood as a lens located on the light-incident side of the prism, also called a light-incident side lens. In this embodiment, there are two light-incident side lenses. The first and second first lenses refer to the light-incident side lens near the object side and the light-incident side lens near the image side (i.e., the prism's incident surface), respectively. A second lens group can be provided at the prism's exit end (i.e., the prism's rear end), and the second lens group may include at least one second lens. The second lens can also be called an exit-side lens. Multiple exit-side lenses may also be present. In this embodiment, a spacer (or SOMA) is provided on the first lens near the object side to prevent stray light risks caused by the lack of an aperture stop on the first lens. Furthermore, in this embodiment, the adhesive material can be arranged on the spacer (or SOMA), and the surface of the spacer or SOMA can be rough, which can reduce stray light and increase the bonding strength.

[0069] In another embodiment of this application, the second mounting groove may have only one step for mounting the first lens, which is the only lens in the first lens group. The upper surface of the first lens may be coated with ink to form an aperture. In modified embodiments, it can also be directly connected to the lens using a sleeve or SOMA (Single-Sleeve-Mask), thus reducing the number of steps in the second mounting groove and reducing the design difficulty and cost of the composite lens barrel. Additionally, it helps to reduce the increase in height of the first lens group positioned in front of the prism. In other words, the number of steps in the second mounting groove at the front end of the prism in this invention is not limited to the three-step scheme described above; those skilled in the art can flexibly adjust it according to actual conditions.

[0070] Furthermore, in conjunction with references Figure 4 and Figure 8 In one embodiment of this application, the lower segment 106b of the composite lens barrel 103 forms a prism mounting groove. The prism mounting groove is square (or rectangular) in a top view. The bottom of the prism mounting groove forms a 45° inclined surface 110. This 45° inclined surface 110 can be a continuous, solid support surface, or it can be a strip-shaped support surface formed by multiple grooves 110b (see reference). Figure 4The supporting surface may have a protruding edge 110a, the top surface of which is 10-20 μm higher than the surface of the supporting surface (here, the surface of the supporting surface refers to the surface of the area in the supporting surface where the protruding edge is not located). During actual installation, the prism's inclined surface is supported by the protruding edge 110a, thereby preventing the prism's inclined surface from contacting the supporting surface of the composite lens barrel too tightly. In this embodiment, the prism's inclined surface is a reflecting surface, which needs to achieve the reversal of the light path based on the principle of total internal reflection. If the prism's inclined surface contacts the bottom supporting surface of the composite lens barrel too tightly, i.e., there is no dielectric layer (e.g., an air gap) between the prism's inclined surface and the bottom supporting surface of the lens barrel, then the refractive index of the lens barrel material will directly affect the total internal reflection function of the prism's inclined surface, and may even cause the total internal reflection function to fail. Therefore, in this embodiment, a raised edge is provided on the 45° bearing surface of the lens barrel to prevent the inclined surface of the prism from contacting the bearing surface of the composite lens barrel too tightly, thereby avoiding the failure of the prism's total internal reflection function. There can be two, three, or more raised edges, as long as they can support the prism and ensure a dielectric layer between the inclined surface of the prism and the bottom bearing surface of the composite lens barrel. (Reference) Figure 4 In one embodiment, the protruding edge 110a can be disposed near the side wall 111 of the composite lens barrel 103, thereby forming an adhesive groove between the side wall 111 of the composite lens barrel 103 and the protruding edge 110a. This allows adhesive to be applied between the protruding edge 110a and the side wall 111 of the composite lens barrel 103 during assembly, facilitating the bonding of the bottom surface of the prism (i.e., the inclined surface of the prism) to the composite lens barrel 103.

[0071] Furthermore, Figure 9 A three-dimensional schematic diagram of the composite lens tube in one embodiment of this application is shown from an approximate top-down perspective. (Reference) Figure 9 In this embodiment, a set of grooves 110b are provided on the bottom bearing surface (i.e., inclined surface 110) of the prism mounting groove of the composite lens barrel 103. That is, the bottom bearing surface of the prism mounting groove is a strip-shaped bearing surface formed by multiple strip-shaped grooves (meaning it appears as a strip when viewed from above). This grooved design can reduce shape deformation caused by shrinkage of the molding or injection molding material during the molding of the lens barrel.

[0072] Furthermore, still referencing Figure 9In one embodiment of this application, the spacing between the grooves 110b on the bottom bearing surface of the prism mounting groove is 0.5-0.8 mm, and the width of a single groove 110b is 0.5-0.8 mm. Furthermore, the grooves 110b are isosceles right triangles in longitudinal section, and the side length of the right-angled side of the isosceles right triangle is preferably 5.5-6 mm. In a preferred embodiment, the bottom bearing surface can be provided with three grooves 110b. This design avoids insufficient strength of the lens barrel due to too many grooves and also solves the problem of easy deformation during lens barrel molding.

[0073] Furthermore, Figure 10 A perspective view of a compound lens barrel according to one embodiment of this application is shown, taken at an approximate side view. Here, the side view refers to the view from the light side. (Refer to the reference...) Figure 9 and Figure 10 In this embodiment, a light window 112 is provided on the light-emitting side of the composite lens barrel 103 to allow light reflected from the prism to exit. Support members 112a suitable for supporting the prism's emitting surface can be provided at the four corners (or other positions on the edge of the light window) of the light window 112. These support members 112a can be integrally formed with the main body of the composite lens barrel 103. Viewed from the side (i.e., from the light-emitting side), each support member 112a can be approximately triangular, which can avoid the light emitted from the prism and prevent vignetting caused by the support members blocking the light. In this embodiment, there are four support members 112a, each located at one corner of the light window. In this embodiment, the lower segment of the composite lens barrel 103 also has two closed sidewalls 111, which correspond to the two sides of the prism. The inner surfaces 111a of the two sidewalls 111 can be provided with grooves 111b to reduce dimensional changes caused by shrinkage of the molding material during the molding of the composite lens barrel 103. On the other hand, the grooves 111b can also accommodate adhesive material so that the two parallel sides of the prism can be bonded and fixed to the two sidewalls 111 of the composite lens barrel 103.

[0074] Furthermore, in one embodiment, the sidewall 111 of the composite lens barrel 103 also has a light-emitting side surface 111c facing the light-emitting side. The light-emitting side surface 111c is the surface connecting the inner side surface 111a and the outer side surface 111d of the sidewall 111. In this embodiment, the light-emitting side surface 111c has an inclination angle, that is, the light-emitting side surface 111c is a slope or at least includes an inclination section (refer to the reference). Figure 9 and Figure 10One end of the groove 111b can be connected to the light-emitting side surface 111c. This design facilitates the demolding and molding of the composite lens barrel and also facilitates the placement of the adhesive material (also known as glue). Specifically, the composite lens barrel 103 can be rotated 90 degrees so that the light-emitting side surface 111c faces upward, and then the adhesive material can be placed on the light-emitting side surface 111c. The adhesive material can flow along the inclined direction of the light-emitting side surface 111c to the inner side surface 111a, and then enter the groove 111b.

[0075] Furthermore, in one embodiment of this application, the reflecting prism can be made of glass, and the first and second lenses can be made of plastic. The height S1 of the prism assembly is less than 8.5 mm, and preferably, the height S1 of the prism assembly can be 6.5-8.5 mm.

[0076] Furthermore, still referencing Figure 1 In one embodiment of this application, a second lens assembly 200 is further provided at the rear end (i.e., the light-emitting side) of the prism. The second lens assembly 200 includes a second lens barrel 201 and at least one second lens installed within the second lens barrel 201. The second lens barrel 201 may include a first barrel 201a and a second barrel 201b. The inner diameter of the first barrel 201a may be larger than that of the second barrel 201b to accommodate a second lens with a larger outer diameter in the second lens group 202. The second barrel 201b may be cylindrical, and the first barrel 201a may be a cut-cylinder shape. The first barrel 201a and the second barrel 201b may be integrally formed. The cut-cylinder shape involves cutting the top and / or bottom of the barrel to form a cut surface shape at the top and / or bottom. This design can reduce the height of the second lens assembly 200, thereby helping to reduce the thickness of the terminal device (e.g., a mobile phone). Furthermore, the second lens disposed in the first barrel may also be a cut-circle shape. The cut portion can be the non-effective diameter of the second lens, or it can include both the non-effective diameter and a portion of the effective diameter.

[0077] Furthermore, in one embodiment of this application, the periscope camera module may include a motor. The second lens assembly may be mounted inside the motor carrier, and the second lens assembly may be movable relative to the motor housing, thereby achieving functions such as autofocus or optical image stabilization. Further, in one embodiment of this application, the photosensitive component may also have chip-based image stabilization (e.g., an OIS chip structure may be used), meaning the photosensitive chip may be movable relative to the housing (e.g., the housing of the camera module) to compensate for camera module shake.

[0078] In one embodiment of this application, a method for assembling a prism assembly is also provided, which includes the following steps S1-S4.

[0079] Step S1: Prepare the composite lens tube and prism, which are separated from each other. The structure and shape of the composite lens tube and prism can be referred to the descriptions of the previous embodiments, and will not be repeated here.

[0080] Step S2 involves taking in the prism (e.g., using a suction nozzle) so that the prism enters the interior of the composite lens barrel from its top surface, passes through the upper section of the composite lens barrel, and is then adhered to the lower section of the composite lens barrel. Adhesive can be applied to the lower section of the composite lens barrel beforehand; the adhesive can be a UV adhesive (or UV glue) for pre-fixation. This UV adhesive can be applied to the 45° support surface of the composite lens barrel. Specifically... Figure 11 The diagram illustrates the glue placement during the assembly process of a prism assembly in one embodiment of this application, for reference only. Figure 11 The UV adhesive 191 (also referred to as pre-fixing adhesive) can be placed in the gap 190 (approximately strip-shaped) between the protruding edge 110a of the bearing surface (also referred to as the inclined bearing surface) and the side wall 111 of the composite lens barrel. After the UV adhesive 191 (i.e., pre-fixing adhesive) is placed, the prism can be inserted from the top surface of the composite lens barrel, then pass through the upper segment of the composite lens barrel and enter the lower segment, with the inclined surface of the prism resting against the 45° bearing surface of the lower segment of the composite lens barrel. At this time, the UV adhesive 191 is cured by UV light irradiation, thereby fixing the prism to the composite lens barrel. The UV light can be emitted from the light-emitting side of the prism. In this step, the UV adhesive 191 (i.e., pre-fixing adhesive) placed between the convex edge 110a and the side wall 111 of the composite lens barrel has a width of 100μm-300μm, and the adhesive width is less than the distance from the convex edge to the side wall of the composite lens barrel to prevent adhesive overflow. The top surface of the convex edge 110a is 10-20μm higher than the surface of the supporting surface (here, the surface of the supporting surface refers to the surface of the area in the supporting surface where the convex edge is not located). In actual installation, the inclined surface of the prism is supported by the convex edge, thereby preventing the inclined surface of the prism from contacting the supporting surface of the composite lens barrel too tightly. In this embodiment, the inclined surface of the prism is a reflective surface, and this reflective surface needs to achieve the reversal of the light path based on the principle of total internal reflection. If the bevel of the prism is in too close contact with the bottom bearing surface of the composite lens tube, resulting in no dielectric layer (e.g., an air gap) between them, the refractive index of the lens tube material will directly affect the total internal reflection function of the prism's bevel, and may even cause it to fail. Therefore, in this embodiment, a convex edge is provided on the 45° bearing surface of the lens tube to prevent the bevel of the prism from being in too close contact with the bearing surface of the composite lens tube (e.g., to create an air gap between them), thereby avoiding the failure of the prism's total internal reflection function.

[0081] Step S3: After installing the prism into the composite lens barrel, lenses and other optical elements are sequentially installed in the second mounting slot of the composite lens barrel. The lenses refer to the incident light side lenses (or first lenses). After the last lens is installed, a rear sleeve is installed to ensure that the first lens group is not affected by stray light. The second mounting slot of the composite lens barrel may have multiple steps. In this step, the multiple first lenses of the first lens group can be installed sequentially according to their outer diameter from smallest to largest.

[0082] Step S4: Apply a fixing adhesive to the light-emitting side of the prism. This adhesive is preferably placed in a groove on the inner side of the composite lens barrel, where the groove prevents the adhesive from overflowing. Additionally, the groove reduces shape changes caused by shrinkage during the molding process of the lens barrel sidewall. In step S2, UV adhesive is used to bond the bottom surface of the prism (i.e., the inclined surface of the prism) to the supporting surface of the composite lens barrel. However, UV adhesive has insufficient bonding reliability and strength. In this step, the composite lens barrel 103 can be rotated 90 degrees so that the light-emitting side surface 111c faces upwards (the position of the light-emitting side surface 111c can be referenced). Figure 9 , Figure 10 and Figure 11 However, it should be noted that Figure 9 , Figure 10 and Figure 11 The composite lens barrel 103 is not actually rotated to the position where the light-emitting side surface 111c faces upward. Reinforcing adhesive 192 is then applied to the light-emitting side surface 111c. The reinforcing adhesive 192 can flow along the inclined direction of the light-emitting side surface 111c to the inner side surface 111a, and then enter the groove 111b, that is, the reinforcing adhesive 192 can enter the channel formed by the groove 111b and the prism sidewall. After the reinforcing adhesive 192 cures, the prism and the composite lens barrel are completely fixed. In this step, the reinforcing adhesive placed in the groove on the inner side of the composite lens barrel can also be called fixing adhesive. It is used to reinforce the adhesion of the pre-fixing adhesive (e.g., the UV adhesive placed on the inclined bearing surface of the composite lens barrel in step S1), so that the prism and the composite lens barrel are completely fixed, thereby improving the reliability and robustness of the prism assembly. In this embodiment, the reinforcing adhesive can also be UV adhesive, which can be cured by exposure. Step S4 is executed after step S2. Specifically, steps S2 and S3 can be executed first, followed by step S4, or step S4 can be executed between steps S2 and S3. When step S4 is executed between steps S2 and S3, the prism can be firmly bonded to the composite lens barrel first, and then the more complex assembly of the first lens group can be carried out (that is, the optical elements of the first lens group are sequentially installed into the composite lens barrel).
