技术领域technical field
本申请涉及成像技术领域,尤其涉及一种摄像模组和电子设备。The present application relates to the field of imaging technologies, and in particular, to a camera module and an electronic device.
背景技术Background technique
目前,摄像模组是手机和电脑等电子设备不可或缺的核心部件之一。然而,在摄像模组的组装或使用过程中,镜头基座受到的外力会经支架传递至滤光片,滤光片极易在外力作用下发生碎裂,降低了摄像模组的可靠性。At present, the camera module is one of the indispensable core components of electronic equipment such as mobile phones and computers. However, during the assembly or use of the camera module, the external force on the lens base will be transmitted to the filter through the bracket, and the filter is easily broken under the action of the external force, which reduces the reliability of the camera module.
发明内容SUMMARY OF THE INVENTION
本申请提供一种摄像模组和电子设备,避免滤光片因受外力而发生碎裂的问题,提高摄像模组的可靠性。The present application provides a camera module and an electronic device, which can avoid the problem that the filter is broken due to external force, and improve the reliability of the camera module.
第一方面,本申请提供一种摄像模组,包括电路板、图像传感器、第一支架、滤光片、第二支架和镜头基座,图像传感器安装于电路板,第一支架安装于电路板的顶侧,第一支架设有对应于图像传感器的通光孔,滤光片安装于第一支架,且覆盖第一支架的通光孔,第二支架安装于电路板的顶侧,且环绕第一支架设置,第二支架的内边缘位于第一支架的外边缘的顶侧,镜头基座安装于第二支架的顶侧。In a first aspect, the present application provides a camera module, comprising a circuit board, an image sensor, a first bracket, a filter, a second bracket and a lens base, the image sensor is mounted on the circuit board, and the first bracket is mounted on the circuit board On the top side of the circuit board, the first bracket is provided with a light-through hole corresponding to the image sensor, the filter is installed on the first bracket and covers the light-through hole of the first bracket, and the second bracket is installed on the top side of the circuit board and surrounds the The first bracket is arranged, the inner edge of the second bracket is located on the top side of the outer edge of the first bracket, and the lens base is mounted on the top side of the second bracket.
本申请所示摄像模组采用分离式的第一支架和第二支架分别支撑滤光片和镜头基座,在摄像模组受到外力作用时,比如镜头基座的侧边受到挤压时,第二支架无法将这些作用力直接传递至滤光片,可有效减少滤光片受外力的影响,即滤光片不会在外力作用下受压或者发生弯曲变形,降低了滤光片因外力作用而失效的风险,提高了摄像模组的可靠性。The camera module shown in this application adopts a separate first bracket and a second bracket to support the filter and the lens base, respectively. When the camera module is subjected to external force, such as when the side of the lens base is squeezed, the The two brackets cannot directly transmit these forces to the filter, which can effectively reduce the influence of the filter by external forces, that is, the filter will not be compressed or deformed under the action of external force, which reduces the effect of external force on the filter. And the risk of failure improves the reliability of the camera module.
此外,由于第二支架的内边缘位于第一支架的外边缘,第一支架和第二支架可复用摄像模组在长度空间上的尺寸,有利于减小摄像模组的长度,实现摄像模组的小型化设计。In addition, since the inner edge of the second bracket is located at the outer edge of the first bracket, the first bracket and the second bracket can reuse the size of the camera module in the length space, which is beneficial to reduce the length of the camera module and realize the camera module. Set of miniaturized designs.
一种实施方式中,摄像模组包括粘接层,粘接层粘接于第一支架的外边缘和第二支架的内边缘之间。即第一支架和第二支架通过粘接层彼此固接,第一支架也可辅助支撑镜头基座,有利于提高第二支架支撑镜头基座的稳定性,进而有助于提高摄像模组的结构稳定性,保证摄像模组的使用可靠性。In one embodiment, the camera module includes an adhesive layer, and the adhesive layer is adhered between the outer edge of the first bracket and the inner edge of the second bracket. That is, the first bracket and the second bracket are fixed to each other through the adhesive layer, and the first bracket can also assist in supporting the lens base, which is beneficial to improve the stability of the second bracket supporting the lens base, thereby helping to improve the stability of the camera module. Structural stability ensures the reliability of the camera module.
一种实施方式中,第二支架设有对应于滤光片的透光孔,第一支架、滤光片和第二支架围合形成间隙。In one embodiment, the second bracket is provided with a light-transmitting hole corresponding to the filter, and the first bracket, the filter and the second bracket are enclosed to form a gap.
一种实施方式中,摄像模组包括捕尘胶部,捕尘胶部填充于间隙。In one embodiment, the camera module includes a dust-catching glue part, and the dust-catching glue part is filled in the gap.
可以理解的是,由于捕尘胶的弹性模量较小,在摄像模组受到外力作用时,比如镜头基座的侧边受到挤压时,捕尘胶部可类似于“海绵体”起到缓冲作用,减缓第二支架传递至第一支架的作用力,进而减缓了传递至滤光片的作用力,降低了滤光片在外力作用下发生破裂而失效的风险。It can be understood that due to the small elastic modulus of the dust-catching glue, when the camera module is subjected to external force, such as when the side of the lens base is squeezed, the dust-catching glue can act like a "sponge". The buffering function slows down the force transmitted from the second bracket to the first bracket, thereby slowing down the force transmitted to the optical filter, and reducing the risk of the optical filter breaking and failing under the action of external force.
其中,捕尘胶部可完全填充于间隙,以完全密封间隙,防止外界的灰尘或水分等杂质通过间隙进入第二支架的内部,避免图像传感器被污染,提高摄像模组的成像品质。Among them, the dust-catching glue part can be completely filled in the gap to completely seal the gap, prevent impurities such as external dust or moisture from entering the inside of the second bracket through the gap, prevent the image sensor from being polluted, and improve the imaging quality of the camera module.
另一种实施方式中,摄像模组包括防水透气膜,所述防水透气膜覆盖间隙的开口。In another embodiment, the camera module includes a waterproof and breathable membrane, and the waterproof and breathable membrane covers the opening of the gap.
在摄像模组的组装或使用过程中,防水透气膜不仅可以防止水分通过间隙进入第二支架的内部,避免图像传感器被水分污染,而且在滤光片的顶侧和底侧之间存在气压差时,顶侧和底侧的空气均可通过防水透气膜和间隙实现空气交换,避免滤光片因气压差而发生碎裂,提高摄像模组的生产良率或使用可靠性。During the assembly or use of the camera module, the waterproof and breathable membrane can not only prevent moisture from entering the inside of the second bracket through the gap and prevent the image sensor from being contaminated by moisture, but also there is a difference in air pressure between the top side and the bottom side of the filter.

Specifically, the dust-catching glue portion 39 completely fills the gap 301 . That is, the dust-catching glue portion 39 has a continuous annular shape, and completely covers the peripheral surface of the optical filter 34 . Wherein, the dust collecting glue part 39 is bonded between the filter 34 and the second bracket 35 . At this time, the dust-catching glue part 39 is bonded between the peripheral surface of the optical filter 34 and the hole wall of the light-transmitting hole 354 of the second bracket 35 to completely seal the gap 301 and prevent impurities such as external dust or moisture from passing through the gap. 301 and the air escape hole (not shown) enter the inside of the second bracket 35 to prevent the image sensor 32 from being polluted and improve the imaging quality of the image sensor 32 . In addition, the dust-catching glue portion 39 can also be adhered to the top surface 331 of the first bracket 33 .
在其他一些实施例中,捕尘胶部39也可以部分填充于间隙301。即捕尘胶部39呈断续环状,且部分覆盖滤光片34的周面。此时,未被填充间隙301的部分可与逃气孔连通。在摄像模组30的后续组装或使用过程中,当滤光片34的顶侧和底侧之间存在气压差时,顶侧和底侧的空气均可通过间隙301和逃气孔进行空气交换,避免滤光片34因气压差而发生碎裂,提高摄像模组30的生产良率或使用可靠性。In some other embodiments, the dust-catching glue part 39 can also be partially filled in the gap 301 . That is, the dust-catching glue portion 39 has an intermittent annular shape, and partially covers the peripheral surface of the optical filter 34 . At this time, the portion of the unfilled gap 301 may communicate with the escape hole. During the subsequent assembly or use of the camera module 30, when there is an air pressure difference between the top side and the bottom side of the filter 34, the air on the top side and the bottom side can be exchanged through the gap 301 and the air escape hole, The filter 34 is prevented from being broken due to air pressure difference, and the production yield or use reliability of the camera module 30 is improved.
在本实施例所示摄像模组30中组装过程中,先利用粘接层60将滤光片34固定于第一支 架33的顶面,再利用粘接层70将第一支架33和第二支架35彼此固定,随后采用粘接层80和粘接层90分别将第一支架33和第二支架35分别固定于电路板31的顶面311,最后在滤光片34的周面和第二支架35的透光孔354的孔壁之间点捕尘胶以形成捕尘胶部39。During the assembly process of the camera module 30 shown in this embodiment, the filter 34 is first fixed on the top surface of the first bracket 33 by the adhesive layer 60 , and then the first bracket 33 and the second bracket 33 are fixed by the adhesive layer 70 . The brackets 35 are fixed to each other, and then the first bracket 33 and the second bracket 35 are respectively fixed to the top surface 311 of the circuit board 31 by the adhesive layer 80 and the adhesive layer 90, and finally the peripheral surface of the filter 34 and the second bracket 35 are respectively fixed. Dust-catching glue is dotted between the walls of the light-transmitting holes 354 of the bracket 35 to form the dust-catching glue portion 39 .
需要说明的是,在安装第一支架33和第二支架35的过程中,由于第一支架33和第二支架35之间逃气孔的存在,滤光片34的顶侧和底侧之间始终可实现气体流动,即滤光片34的顶侧和底侧之间的气体可以进行交流,也即滤光片34的顶侧和底侧之间无气压差,滤光片34不会因顶侧和底侧之间存在气压差而发生碎裂,有助于提高摄像模组30的生产良率。随后在点捕尘胶的过程中,捕尘胶可密封逃气孔,隔绝滤光片34的顶侧和底侧之间的气体流动,实现图像传感器32的有效密封。It should be noted that, in the process of installing the first bracket 33 and the second bracket 35, due to the existence of the air escape hole between the first bracket 33 and the second bracket 35, the top side and the bottom side of the optical filter 34 are always between the top side and the bottom side. The gas flow can be realized, that is, the gas between the top side and the bottom side of the optical filter 34 can be exchanged, that is, there is no air pressure difference between the top side and the bottom side of the optical filter 34, and the optical filter 34 will not be affected by the top side and the bottom side of the optical filter 34. There is an air pressure difference between the side and the bottom side to cause the chipping, which helps to improve the production yield of the camera module 30 . Then, during the process of spotting the dust-catching glue, the dust-catching glue can seal the air escape hole, isolate the gas flow between the top side and the bottom side of the optical filter 34 , and realize the effective sealing of the image sensor 32 .
换言之,本实施例所示摄像模组30的设计,不仅取消了现有支架中逃气孔,还取消了密封逃气孔的工序。本实施例所示摄像模组30可直接利用粘接层70在第一支架33和第二支架35之间形成逃气孔,并将封逃气孔和点捕尘胶工序合为一体,不仅节省了摄像模组30的成本,还简化了摄像模组30的工序,有助于提高摄像模组30的生产效率。In other words, the design of the camera module 30 shown in this embodiment not only cancels the air escape hole in the existing bracket, but also cancels the process of sealing the air escape hole. The camera module 30 shown in this embodiment can directly use the adhesive layer 70 to form an air escape hole between the first bracket 33 and the second support 35, and integrate the air escape hole sealing and dust-catching glue processes into one, which not only saves money The cost of the camera module 30 also simplifies the process of the camera module 30 , which helps to improve the production efficiency of the camera module 30 .

The lens base 36 includes a mounting slot 363 , and the opening of the mounting slot 363 is located in the middle area of the top surface 361 . The mounting groove 363 extends from the top surface 361 of the lens base 36 toward the bottom surface 362 , and penetrates through the bottom surface 362 of the lens base 36 . That is, the mounting groove 363 penetrates the lens base 36 from the height direction of the lens base 36 . Specifically, the installation groove 363 corresponds to the light-transmitting hole 354 of the second bracket 35 . That is, the mounting groove 363 corresponds to the optical filter 34 . The light outside the camera module 30 can enter the filter 34 from the installation slot 363 and the light-transmitting hole 354 of the second bracket 35 , and is filtered by the filter 34 before being received by the image sensor 32 .
镜头37安装于镜头基座36的内侧。具体的,镜头37安装于镜头基座36的安装槽363,用以会聚摄像模组30外部的光线。也即,镜头37能够会聚外部的光线,并将会聚后的外部光线自滤光片34投射至图像传感器32。示例性的,镜头37可通过粘接的方式与镜头基座36相互固定。比如,摄像模组30可包括粘接层92,粘接层92粘接于镜头37和镜头基座36之间。其中,镜头37可以包括镜筒和固定在镜筒内侧的透镜组。此时,透镜组的透镜数量可以是多片,比如5片、或6片、或7片、或8片等。The lens 37 is attached to the inner side of the lens base 36 . Specifically, the lens 37 is installed in the installation groove 363 of the lens base 36 for condensing the light outside the camera module 30 . That is, the lens 37 can condense the external light, and project the condensed external light from the filter 34 to the image sensor 32 . Exemplarily, the lens 37 may be fixed to the lens base 36 by means of bonding. For example, the camera module 30 may include an adhesive layer 92 , and the adhesive layer 92 is adhered between the lens 37 and the lens base 36 . The lens 37 may include a lens barrel and a lens group fixed inside the lens barrel. At this time, the number of lenses in the lens group may be multiple, such as 5, or 6, or 7, or 8, and so on.

Exemplarily, the motor can be an auto-focus motor, and the auto-focus motor can drive the lens group to move in a direction parallel to the optical axis of the lens 37 . Alternatively, the motor may be an optical anti-shake motor, which can drive the lens group to move on a plane perpendicular to the optical axis of the lens 37 , or drive the lens group to flip to tilt relative to the optical axis of the lens 37 . Alternatively, the motors may be autofocus and optical image stabilization motors. Exemplarily, the motor may be a voice coil motor (VCM), or a memory alloy motor or the like. This application does not strictly limit the specific function and type of the motor. In some other embodiments, the lens base 36 can also be a bracket structure. At this time, the camera module 30 is a fixed-focus module.
本实施例所示摄像模组30采用分离式的第一支架33和第二支架35分别支撑滤光片34 和镜头基座36,在摄像模组30受到外力作用时,比如镜头基座36的侧边受到挤压或者沿Z轴方向受到挤压时,第二支架35无法将这些作用力直接传递至滤光片34,可有效减少滤光片34受外力的影响,即滤光片34不会在外力作用下受压或者发生弯曲变形,降低了滤光片34因外力作用而失效的风险。The camera module 30 shown in this embodiment adopts a separate first bracket 33 and a second bracket 35 to support the filter 34 and the lens base 36 respectively. When the camera module 30 is subjected to an external force, such as the lens base 36 When the side is squeezed or squeezed along the Z-axis direction, the second bracket 35 cannot directly transmit these forces to the filter 34, which can effectively reduce the influence of the filter 34 by external forces, that is, the filter 34 does not Under the action of external force, it will be compressed or deformed by bending, which reduces the risk of failure of the optical filter 34 due to the action of external force.
此外,第二支架35与滤光片34之间通过捕尘胶部39连接,由于捕尘胶部39的弹性模量非常低,还可以类似于“海绵体”起到缓冲作用,减缓第二支架35传递至第一支架33的作用力,进而减缓了传递至滤光片34的作用力,降低了滤光片34在外力作用下发生破裂而失效的风险。In addition, the second bracket 35 and the filter 34 are connected by the dust-catching glue part 39. Since the elastic modulus of the dust-catching glue part 39 is very low, it can also play a buffering role similar to the "sponge body" and slow down the second bracket 35. The force transmitted by the bracket 35 to the first bracket 33 further reduces the force transmitted to the optical filter 34 and reduces the risk of rupture and failure of the optical filter 34 under the action of external force.

Specifically, the first bracket 33 is installed in the second installation groove 315 . A part of the first bracket 33 is located in the second installation groove 315 , and the legs 337 of the first bracket 33 are fixed to the substrate 31 b of the circuit board 31 .

此外,摄像模组30还包括第二导热胶层51,第二导热胶层51连接于第一支架33和衬底31b之间。即第一支架33可通过第二导热胶层51固接于衬底31,以通过第二导热胶层51接收来自衬底31b的热量,实现对衬底31b的快速散热。其中,第二导热胶层51包括两个子导热胶层(图未标),每一子导热胶层连接于一个子支脚337a和衬底31b之间。In addition, the camera module 30 further includes a second thermally conductive adhesive layer 51, and the second thermally conductive adhesive layer 51 is connected between the first bracket 33 and the substrate 31b. That is, the first bracket 33 can be fixed to the substrate 31 through the second thermally conductive adhesive layer 51 , so as to receive heat from the substrate 31 b through the second thermally conductive adhesive layer 51 , so as to achieve rapid heat dissipation to the substrate 31 b . The second thermally conductive adhesive layer 51 includes two sub-thermally conductive adhesive layers (not shown), and each sub-thermally conductive adhesive layer is connected between one of the sub-legs 337a and the substrate 31b.
本实施例所示摄像模组30中,图像传感器32工作时的热量可经第一导热胶层50传递至衬底31b,部分热量可经衬底31b的底面和周面传递至外界环境中,部分热量可经第二导热胶层51传递至第一支架33,经第一支架33传递至外界环境,相当于增加了图像传感器32 的散热通道,提高了图像传感器32的散热效率,避免了图像传感器32因高温而故障的问题,提高了摄像模组30的可靠性。In the camera module 30 shown in this embodiment, the heat of the image sensor 32 during operation can be transferred to the substrate 31b through the first thermally conductive adhesive layer 50, and part of the heat can be transferred to the external environment through the bottom surface and the peripheral surface of the substrate 31b, Part of the heat can be transferred to the first bracket 33 through the second thermal conductive adhesive layer 51, and transferred to the external environment through the first bracket 33, which is equivalent to increasing the heat dissipation channel of the image sensor 32, improving the heat dissipation efficiency of the image sensor 32, and avoiding the image sensor 32. The problem that the sensor 32 fails due to high temperature improves the reliability of the camera module 30 .
滤光片34安装于第一支架33且覆盖通光孔334。具体的,滤光片34安装于第一支架33的顶面331,且位于固定部336的两个子固定部336a(如图25所示)之间。其中,滤光片34与固定部336的两个子固定部336a彼此间隔。The filter 34 is mounted on the first bracket 33 and covers the light-transmitting hole 334 . Specifically, the filter 34 is mounted on the top surface 331 of the first bracket 33 and is located between the two sub-fixing portions 336 a of the fixing portion 336 (as shown in FIG. 25 ).

At this time, each sub-fixing portion 336a is spaced apart from the side wall of the sub-mounting slot, and the gap between the two is equal to or greater than 0.1 mm.
此时,第一支架33、滤光片34和第二支架35围合形成间隙301,捕尘胶部39填充于间隙301内。可以理解的是,由于固定部336的存在,在点捕尘胶的过程中,捕尘胶的流动路径更为曲折,因而不易经第一支架33和第二支架35之间的逃气孔(图未示)进入第二支架35的内部,避免了捕尘胶影响图像传感器32正常工作的问题。At this time, the first bracket 33 , the filter 34 and the second bracket 35 are enclosed to form a gap 301 , and the dust-catching glue portion 39 is filled in the gap 301 . It can be understood that due to the existence of the fixing portion 336, the flow path of the dust-catching glue is more tortuous in the process of spotting the dust-catching glue, so it is not easy to pass through the air escape hole between the first bracket 33 and the second bracket 35 (Fig. (not shown) into the inside of the second bracket 35 to avoid the problem that the dust-catching glue affects the normal operation of the image sensor 32 .
