Technical Field

Background

With the popularization of mobile electronic devices, technologies related to camera modules applied to mobile electronic devices for assisting users in acquiring images (e.g., videos or images) have been rapidly developed and advanced.

For example, in an image pickup module having an autofocus function, a motor is configured to drive an optical lens to move along an optical axis to perform autofocus.

In the existing packaging process of the camera module, a module factory purchases components such as a motor, an optical lens, a photosensitive chip and the like from different suppliers respectively, and packages the components to obtain a complete camera module. That is, in the existing packaging process of the camera module, the components such as the motor, the optical lens, and the photosensitive chip are provided by different suppliers, but the technical fields to which the components belong are different, the production environments are different, the requirements for the components are different, and the components need to be matched with each other to reduce the mutual interference. These reasons have led to the fact that the packaging process of current camera modules is relatively complicated, the industry chain length involved, and the cost of camera modules increase because of unnecessary assembly processes and parts.

Therefore, an optimized assembly method for a camera module is required.

Detailed Description

Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein.

Summary of the application

As described above, in the conventional process for packaging a camera module, a module factory purchases components such as a motor, an optical lens, and a photo sensor chip from different suppliers, and packages the components to obtain a complete camera module. That is, in the existing packaging process of the camera module, the components such as the motor, the optical lens and the photo sensor chip are provided by different suppliers, but because the technical fields to which the components belong are different, the production environments are different, the requirements for the components are different, the components need to be matched with each other, and the interference between the components is reduced, which results in that the existing packaging process of the camera module is relatively complicated, the related industrial chain length is long, and the cost of the camera module is increased due to redundant assembly processes and parts.

More specifically, the motor is a relatively complex component of the various components of the camera module, but the manufacturing environment requires relatively low components. The dust-free class requirements of motor manufacturing plants are relatively low, with the environment of the plant having much more dust than the manufacturing plant of the optical lens or the light-sensitive chip. Therefore, when the module factory adopts the traditional packaging technology, namely, the assembled motor is purchased from the motor factory for packaging the camera module, the dust carried on the motor can cause serious dust pollution of the camera module.

Moreover, even if the motor is cleaned after being packaged as a standard component in a motor factory, dust may still be hidden inside the motor due to the complexity of the internal structure of the motor, and may escape from the inside of the motor and fall on the lens of the optical lens or the photosensitive surface of the photosensitive chip during the subsequent assembly process or the use process of the camera module, so that a black spot may exist in an image formed by the camera module, which may affect the imaging quality of the camera module.

In addition, with the development of mobile electronic devices, the camera module is increasingly developed towards large pixels, large apertures, light weight and thin thickness, which makes the requirements on the size and structure of the camera module higher and higher. However, since the motor exists in the form of a complete module in the camera module, which is an almost unchangeable variable in the size and structural design of the camera module, there are few module factories trying to optimize the structural and dimensional design of the camera module from the technical idea of optimizing the motor structure and assembly process.

In view of the above technical problems, the technical idea of the present application is that the assembly of the motor is integrated in the assembly scheme of the camera module, and the assembly process of the motor becomes a part of the module packaging process, so that the assembly process of the camera module can be optimized from the perspective of a longer industrial chain, and the assembly integration level and the assembly efficiency of the camera module are improved. That is, in splitting the motor into a plurality of sub-modules and participating in the assembly scheme of the camera module, the number of the whole assembly processes of the camera module is reduced in such a way, and the productivity and the efficiency are improved. Accordingly, under such a technical concept, the internal structure of the motor may also be heterogeneous through a packaging process to optimize the layout of components inside the motor.

Based on this, the present application provides a motor prepared by an integrated assembly process, comprising: a motor base including a base main body and a first elastic member integrally extending inward from an upper end portion of the base main body; a second elastic member mounted at a lower end portion of the base main body; a motor carrier mounted in a suspended manner between the first elastic element and the second elastic element, the motor carrier having a mounting cavity, the lens group being mounted in the mounting cavity; and a coil and a magnet which are used for driving the motor carrier to move and are oppositely arranged.

Based on this, the application provides a module of making a video recording that is prepared by integrated form assembly process, and it includes: a photosensitive assembly; a motor mounted to the photosensitive assembly; and a lens group held on a photosensitive path of the photosensitive assembly in a manner of being mounted on the motor, wherein the lens group includes at least one optical lens; wherein, the motor includes: a motor base including a base main body and a first elastic member integrally extending inward from an upper end portion of the base main body; a second elastic member mounted at a lower end portion of the base main body; a motor carrier mounted in a suspended manner between the first elastic element and the second elastic element, the motor carrier having a mounting cavity, the lens group being mounted in the mounting cavity; and a coil and a magnet which are used for driving the motor carrier to move and are oppositely arranged.

Based on this, this application still provides the method of assembling of a camera module, and it includes: providing a photosensitive assembly; forming a motor base, wherein the motor base includes a base main body and a first elastic member integrally extending inward from an upper end portion of the base main body; mounting the motor base on the photosensitive assembly; mounting a motor carrier mounted with a lens group and a coil in the motor base in a flip-chip manner, wherein the upper end of the motor carrier abuts against the first elastic element; mounting a second elastic element at a lower end of the motor base, wherein the lower end of the motor carrier abuts against the second elastic element, so that the motor carrier is suspended and clamped between the first elastic element and the second elastic element; mounting a magnet corresponding to the coil on the motor base; and a motor housing is externally sleeved to encapsulate the magnet, the coil and the motor carrier in an encapsulation cavity formed by the motor housing and the motor base.

Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.

Exemplary Camera Module

As shown in fig. 1 and 2, a camera module according to an embodiment of the present application is illustrated, wherein the camera module is prepared based on an integrated assembly process (i.e., an assembly process of a motor is integrated in an assembly process of the camera module). Correspondingly, the camera module includes: the image sensor comprises a photosensitive assembly 10, a motor 20 mounted on the photosensitive assembly 10, and a lens group 30 held on a photosensitive path of the photosensitive assembly 10 in a manner of being mounted in the motor 20, wherein the motor 20 is used for driving the lens group 30 to move so as to adjust optical performance, such as automatic focusing, optical anti-shake, optical zooming, and the like.

Accordingly, as shown in fig. 1 and 2, in the embodiment of the present application, the photosensitive assembly 10 includes: the device comprises a circuit board 11, a photosensitive chip 12, a lens base 13 and a filter element 14, wherein the circuit board 11 is used as a mounting substrate of the photosensitive assembly 10. Specifically, the light sensing chip 12 is electrically connected to the circuit board 11 (for example, in an example, the light sensing chip 12 is mounted on the upper surface of the circuit board 11 and electrically connected to the circuit board 11 by a gold wire), so as to provide the control circuit and the electric energy required by the operation of the light sensing chip 12 through the circuit board 11.

The lens holder 13 is formed on the circuit board 11 for supporting other components, wherein the lens holder 13 has an optical window corresponding to at least a light sensing area of the light sensing chip 12. For example, in one particular example of the present application, the lens holder 13 is implemented as a separately molded plastic bracket that is attached to the surface of the circuit board 11 by an adhesive and is used to support other components. Of course, in other examples of the present application, the mirror base 13 can also be formed on the circuit board 11 in other manners, for example, the mirror base 13 is implemented as a molded mirror base 13 which is integrally formed on a predetermined position of the circuit board 11 through a molding process.

Further, in some specific examples of the present application, the filter element 14 may be mounted on the lens base 13, so that the filter element 14 is maintained on a photosensitive path of the photosensitive chip 12, so that, in a process that external light passes through the filter element 14 to reach the photosensitive chip 12, stray light in the external light can be filtered by the filter element 14 to improve imaging quality. It is worth mentioning that in other examples of the present application, the filter element 14 can also be mounted on the mirror base 13 in other ways, for example, a filter element holder is first provided on the mirror base 13, and then the filter element 14 is mounted on the filter element holder, that is, in this example, the filter element 14 can be indirectly mounted on the mirror base 13 through other supports. Of course, in other examples of the present application, the filter element 14 can also be installed at other positions of the image capturing module, for example, the filter element 14 is formed in the lens group 30 (for example, attached as a layer of filter film on a surface of one of the optical lenses of the lens group 30), and the present application is not limited thereto.

In order to increase the bottom strength of the photosensitive assembly 10, in some examples of the present application, the photosensitive assembly 10 further includes a reinforcing plate (not shown) disposed on the lower surface of the circuit board 11, for example, a steel plate may be disposed on the lower surface of the circuit board 11 to reinforce the strength of the circuit board 11 by the steel plate. Accordingly, the reinforcing plate may be configured to have a shape and a size conforming to the wiring board 11 to reinforce the entirety of the wiring board 11 after being stacked on the lower surface of the wiring board 11.

Further, in the example shown in fig. 1 and 2, the motor 20 is mounted on the upper surface of the mirror base 13, and it should be understood that in other examples of the present application, the motor 20 may also be mounted on other positions of the photosensitive assembly 10, for example, on the circuit board 11 or the reinforcing plate, which is not limited by the present application. In particular, in the embodiment of the present application, the assembly process of the motor 20 is completed during the assembly process of the camera module, that is, the motor 20 is disassembled into a plurality of parts and participates in the assembly process of the camera module, so that the overall structure and size of the motor 20 and the camera module are optimized. It will be appreciated that integrating the assembly process of the motor 20 into the assembly process of the camera module provides space and new possibilities for adjustment and optimization of the internal structure of the motor 20.

In the example illustrated in fig. 1 and 2, the motor 20 is implemented as an electromagnetic motor comprising a motor base 21 mounted to the mirror base 13. In particular, in the present embodiment, the structure of the motor base 21 is made heterogeneous. Specifically, as shown in fig. 3A, in this embodiment, the motor base 21 includes a base main body 211 and a first elastic member 22 integrally extending inward from an upper end portion of the base main body 211. That is, in the present embodiment, the base main body 211 and the first elastic member 22 have an integrated structure, so that the relative positional relationship between the base main body 211 and the first elastic member 22 can be fixed after being molded during the packaging of the motor 20.

As shown in fig. 1 to 3A, the motor 20 further includes: and a second elastic member 23 installed at a lower end portion of the base main body 211. That is, compared to the conventional motor, in the embodiment of the present application, the first elastic element 22 and the second elastic element 23 are simultaneously mounted on the motor base 21, or the first elastic element 22 and the second elastic element 23 are simultaneously mounted with reference to the motor base 21, so that the structural configuration is advantageous for improving the mounting uniformity between the first elastic element 22 and the second elastic element 23.

More specifically, in this embodiment, the base body 211 has a mounting surface at a lower end portion thereof, wherein the second elastic member 23 may be fixed to the mounting surface by means of heat staking or glue bonding, or the like.

In the process of manufacturing the camera module, the base main body 211 may be provided, wherein the base main body 211 has a main body portion 212 and at least two positioning pillars 213 extending upward from a corner region of the main body portion 212. Then, the first elastic element 22 is disposed on the at least two positioning pillars 213 such that the height position of the first elastic element 22 on the at least two positioning pillars 213 is determined, so that after the first elastic element 22 is integrally combined with the at least two positioning pillars 213 through an injection molding process, the relative position relationship between the base main body 211 and the first elastic element 22 can be fixed after being molded.

In a specific example, the substrate body 211 may be formed through an injection molding process, that is, the substrate body 211 is an injection molded part, so that a corresponding portion of an outer surface of the substrate body 211 may be implemented as a plane having a relatively high flatness. Preferably, in this specific example, the base body 211 may provide a flat mounting surface for the second elastic element 23 and simultaneously provide a flat mounting surface for the first elastic element 22, so that after the first elastic element 22 is integrally formed with the base body 211 through an injection molding process and the second elastic element 23 is fixed to the mounting surface through a hot riveting or bonding process, the first elastic element 22 and the second elastic element 23 have relatively high parallelism and consistency. That is, preferably, the upper surfaces of the at least two positioning pillars 213 are flat surfaces, and the mounting surface is a flat surface.

It should be noted that, in other examples of the present application, the first elastic element 22 may also be integrally formed with the base main body 211 in other manners, for example, the first elastic element 22 is directly integrally formed with the motor base 21 through an insert injection molding process, which is not limited by the present application. It should be noted that, in other examples of the present application, the motor base 21 and the mirror base 13 of the photosensitive assembly 10 may also have an integrated structure, for example, the motor base 21 and the mirror base 13 are integrally formed and attached to the upper surface of the circuit board 11 through an injection molding process, which is not limited in the present application.

Further, as shown in fig. 3A, the motor 20 further includes: a motor carrier 24 mounted in a suspended manner between the first elastic element 22 and the second elastic element 23; and a coil 25 and a magnet 26 which are used for driving the motor carrier 24 to move and are oppositely arranged, wherein the motor carrier 24 is provided with a mounting cavity 240, and the lens group 30 is mounted in the mounting cavity 240. In order to prevent the interior of the motor 20 from being contaminated and electromagnetically shielded, the motor 20 further includes a motor housing 27 for enclosing the motor base 21, the motor carrier 24 and the coil 25-magnet 26 pair, wherein the motor housing 27 has an opening corresponding to the lens group 30 to allow external imaging light to enter the interior of the camera module through the opening.

In the example illustrated in fig. 1 and 2, the coil 25 is formed by winding an enameled wire, and the coil 25 is shaped by hot air baking in the winding process. In a specific implementation, the coil 25 may be wound directly onto the motor carrier 24 or, alternatively, may be mounted to the carrier after being pre-formed. The magnet 26 is opposed to the coil 25, and provides a permanent magnetic field to the coil 25. In a specific implementation, the magnet 26 may be mounted on the motor base 21 or mounted on the outer housing, and the magnet 26 is disposed opposite to the coil 25.

It should be understood that, in other examples of the present application, the installation position relationship between the coil 25 and the magnet 26 may be adjusted, and the installation positions of the coil 25 and the magnet 26 may be interchanged, that is, the magnet 26 is installed on the motor carrier 24 and the coil 25 is installed on the motor base 21 or the motor housing 27, which is not limited by the present application.

More specifically, as shown in fig. 1 to 4, in the embodiment of the present application, the first elastic element 22 integrally formed with the motor base 21 through an injection molding process includes a positioning portion for positioning and a deformable portion capable of being deformed, wherein the deformable portion and the positioning portion are integrally formed and elastically connected, so that the deformable portion is deformable relative to the positioning portion when an external force is applied to the deformable portion. It should be understood that in the embodiment of the present application, the motor carrier 24 is suspended on the first elastic element 22, so that when the motor carrier 24 is displaced upward by the coil 25 and the magnet 26, the first elastic element 22 generates a reactive damping force to balance the electromagnetic force, so that the movement of the motor carrier 24 is smoother.

Accordingly, the second elastic element 23 mounted at the lower end of the base main body 211 includes a positioning portion for positioning and a deformable portion capable of being deformed, wherein the positioning portion is integrally formed with the deformable portion and is elastically connected to the deformable portion, so that the deformable portion can be deformed relative to the positioning portion when an external force is applied to the deformable portion.
