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, components such as the motor, the optical lens, the photosensitive chip, and the like are provided by different suppliers, but since the technical fields to which the components belong are different, the production environments are different, and the requirements on the components are different, the components need to be matched with each other, so as to reduce mutual interference, 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 structure 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 photo chip. Therefore, when the module factory adopts the traditional packaging technology, namely, the motor which is assembled and purchased from the motor factory is used for packaging the camera module, the dust carried on the motor can cause the 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 attempting to optimize the structural and dimensional design of the camera module from the technical idea of optimizing the motor structure and the 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 body, a first elastic element extending inward from an upper end of the base body, and a second elastic element integrally extending inward from a lower end of the base body, wherein the second elastic element includes a second entire outer profile, a second entire inner profile, and at least one second spring wire extending between the second entire inner profile and the second entire outer profile, wherein at least a portion of the second entire outer profile is integrally engaged with the lower end of the base body, and the second spring wire extends from a circumferential direction of the second entire outer profile and is bent to the second entire inner profile; 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 for mounting a lens assembly including at least one optical lens therein; 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 such a manner as to be mounted to the motor, wherein the lens group includes at least one optical lens; wherein, the motor includes: a motor base including a base body, a first elastic element extending inward from an upper end of the base body, and a second elastic element integrally extending inward from a lower end of the base body, wherein the second elastic element includes a second entire outer profile, a second entire inner profile, and at least one second spring wire extending between the second entire inner profile and the second entire outer profile, wherein at least a portion of the second entire outer profile is integrally engaged with the lower end of the base body, and the second spring wire extends from a circumferential direction of the second entire outer profile and is bent to the second entire inner profile; 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 for mounting a lens assembly including at least one optical lens therein; 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 substrate, wherein the motor substrate comprises a substrate main body, a first elastic element integrally extending inwards from the upper end of the substrate main body, and a second elastic element extending inwards from the lower end of the substrate main body, wherein the first elastic element comprises a first whole outline, and at least one first spring wire extending between the first whole outline and the first whole outline, at least one part of the first whole outline is integrally embedded in the upper end of the substrate main body, and the first spring wire extends out from the circumference of the first whole outline and bends to extend to the first whole outline; mounting the motor base on the photosensitive assembly; installing a motor carrier with a lens group and a coil installed therein in the motor base, wherein 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 optical lens system 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 fig. 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 mirror 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 photosensitive chip 12 is electrically connected to the circuit board 11 (for example, in an example, the photosensitive chip 12 is mounted on the upper surface of the circuit board 11 and electrically connected to the circuit board 11 by means of gold wire bonding), so as to provide the circuit board 11 with a control circuit and electric energy required by the operation of the photosensitive chip 12.

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 photosensitive region of the photosensitive 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, a second elastic element 23 integrally extending from a lower end of the base main body 211 inward, and a first elastic element 22 attached to an upper end of the base main body 211. More specifically, in the embodiment of the present application, the base main body 211 has a main body portion 212 and at least two positioning pillars 213 extending upward from corner regions of the main body portion 212, wherein the second elastic element 23 is integrally combined with the main body portion 212, and the first elastic element 22 is attached to the at least two positioning pillars 213.

That is, in the present embodiment, the base main body 211 and the second elastic member 23 have an integrated structure, so that the relative positional relationship between the base main body 211 and the second elastic member 23 can be fixed after being molded during the packaging of the motor 20. Also, in this embodiment, the first elastic member 22 is attached as a separate member to the upper end portion of the base main body 211. That is, compared to the conventional motor, in the embodiment of the present application, the second elastic element 23 and the first elastic element 22 are simultaneously mounted on the motor base 21, or the second elastic element 23 and the first elastic element 22 are simultaneously mounted with reference to the motor base 21, so that the structural configuration is advantageous for improving the mounting uniformity between the second elastic element 23 and the first elastic element 22.

In the assembly process of the camera module, the substrate body 211 may be provided first, for example, the substrate body 211 is formed by an injection molding process; then, the second elastic member 23 is integrally coupled to the base main body 211 through an injection molding process. Preferably, a portion of the upper surface of the base main body 211 for mounting the second elastic element 23 has a relatively high flatness, so as to improve the relative positional accuracy of the base main body 211 and the second elastic element 23 after being molded. Accordingly, by adjusting the molding surface of the injection mold, the portion of the upper surface of the base main body 211 for mounting the second elastic element 23 can be made to have relatively high flatness.

Fig. 3B illustrates a schematic diagram of a variant implementation of the motor 20 of the camera module according to an embodiment of the present application. In this modified embodiment, the structure of the motor base 21 is also made heterogeneous. Specifically, as shown in fig. 3B, in this modified 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 embodiment of the present application, 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. Also, in this modified embodiment, the second elastic member 23 is attached to the lower end portion of the base main body 211 as a separate component, for example, the base main body 211 has an attachment surface at the lower end portion thereof, and the second elastic member 23 may be fixed to the attachment surface by means of heat staking, glue bonding, or the like.

Accordingly, compared to the conventional motor, in this modified embodiment, 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 the motor base 21 as a reference, which is advantageous for improving the mounting consistency between the first elastic element 22 and the second elastic element 23.

Fig. 3C illustrates a schematic diagram of another variant implementation of the motor 20 of the camera module according to the embodiment of the present application, wherein in the variant embodiment as illustrated in fig. 3C, the structure of the motor base 21 is also heterogeneous. Specifically, as shown in fig. 3C, in this modified embodiment, the motor base 21 includes a base main body 211, a first elastic member 22 integrally extending inward from an upper end portion of the base main body 211, and a second elastic member 23 integrally extending inward from a lower end portion of the base main body 211. In the embodiment of the present application, the base main body 211 has a main body portion 212 and at least two positioning pillars 213 extending upward from corner regions of the main body portion 212, wherein the second elastic element 23 is integrally combined with the main body portion 212, and the first elastic element 22 is integrally combined with the at least two positioning pillars 213. That is, in this modified embodiment, the base main body 211, the first elastic member 22, and the second elastic member 23 have an integrated structure, so that the relative positional relationship among the base main body 211, the first elastic member 22, and the second elastic member 23 can be fixed after being molded in the packaging process of the motor 20.

Meanwhile, it should be understood that, compared to the conventional motor, in the embodiment of the present application, the first elastic element 22 and the second elastic element 23 are integrally formed on the motor base 21 at the same time, or the first elastic element 22 and the second elastic element 23 are installed on the basis of the motor base 21 at the same time, by such a structural configuration, it is beneficial to improve the installation consistency between the first elastic element 22 and the second elastic element 23, for example, it is beneficial to improve the parallelism between the first elastic element 22 and the second elastic element 23.

Accordingly, in the modified embodiment as illustrated in fig. 3C, the first elastic element 22 is integrally coupled to the at least two positioning pillars 213 through an injection molding process, and the second elastic element 23 is integrally coupled to the main body portion 212 through an injection molding process, in such a manner that the first elastic element 22 integrally extends inward from the upper end portion of the base main body 211 and the second elastic element 23 integrally extends inward from the lower end portion of the base main body 211.

In this modified embodiment, in a specific example of the manufacturing process of the camera module, the main body portion 212 may be provided first, and the main body portion 212 may be formed, for example, by an injection molding process. It should be noted that when the main body portion 212 is formed by injection molding, the main body portion 212 is an injection molded part, so that it can provide a flat surface for mounting the second elastic element 23, that is, when the main body portion 212 is an injection molded part, a second mounting surface of the upper surface of the main body portion 212 for mounting the second elastic element 23 is a flat surface. Next, the second elastic element 23 is disposed on a second mounting surface of the main body portion 212 (for example, attached to the second mounting surface by an adhesive) and the second elastic element 23 is integrally bonded to the upper surface of the main body portion 212 by an injection molding process to obtain an intermediate product. Then, at least two positioning pillars 213 extending upwards are formed in the corner regions of the intermediate product through an injection molding process. Then, the first elastic element 22 is disposed on the upper surfaces of the at least two positioning pillars 213, and the first elastic element 22 is integrally combined with the upper surfaces of the at least two positioning pillars 213 through an injection molding process to form the motor base 21.

It should be noted that, in this specific example, both the main body portion 212 and the at least two positioning posts 213 may be formed by an injection molding process, so that a first mounting surface of the positioning post 213 for mounting the first elastic element 22 is a flat surface, and a second mounting surface of the main body portion 212 for mounting the second elastic element 23 is a flat surface, in this way, not only the accuracy of the relative positional relationship between the second elastic element 23 and the main body portion 212 and the accuracy of the relative positional relationship between the first elastic element 22 and the at least two positioning posts 213, but also the relatively high parallelism and consistency between the first elastic element 22 and the second elastic element 23 can be ensured.

In this modified embodiment, the first elastic element 22 and the second elastic element 23 may also be integrally formed with the base main body 211 by other means, for example, the first elastic element 22 and the second elastic element 23 are directly integrally formed with the motor base 21 by an insert molding process. Specifically, in a specific example of the manufacturing process of the camera module, the first elastic element 22 and the second elastic element 23 may be first fixed at preset positions of an injection mold; then, the motor base 21 is formed through an injection molding process in which the first elastic member 22 integrally extends inward from the upper end portion of the base main body 211 and the second elastic member 23 integrally extends inward from the lower end portion of the base main body 211. That is, in this particular example, the first elastic element 22 and the second elastic element 23 are first provided and put and fixed in place in an injection mold, and then injection molded with plastic. Accordingly, the first elastic member 22 and the second elastic member 23 are embedded therein by the cooling-solidified plastic to obtain the motor base 21.

Accordingly, the first spring wire 223 includes at least a first circumferential section extending along the circumferential direction of the first entire profile 221 and at least a first radial section extending along the radial direction of the first entire profile 221, so that the overall length of the first spring wire 223 can be maintained or even increased in a limited space by changing the extending manner of the first spring wire 223 (first extending from the circumferential direction of the first entire profile 221 and then extending along the radial direction of the first entire profile 221).

Accordingly, the first spring wire 223 has a limited degree of deformation, wherein the degree of deformation of the first spring wire 223 is smaller as the length of the first spring wire 223 is longer, under the same stroke. That is, as the length of the first spring wire 223 is longer, the stroke of the motor 20 can be made longer with the same degree of deformation.

Fig. 6B illustrates a schematic diagram of another implementation of a variation of the first elastic element 22 or the second elastic element 23 of the motor 20 according to an embodiment of the present application. It should be noted that, in the embodiment of the present application, if the first elastic element 22 and the second elastic element 23 are integrally formed with the motor base 21 through an injection molding process, at least a portion of the entire outer contour of the first elastic element 22 or the second elastic element 23 is embedded in the motor base 21, in this case, the space between the entire outer contour of the first elastic element 22 and the entire outer contour for disposing the spring wire is reduced without increasing the molding size.

In order to solve the technical problem, the inventor of the present application provides a novel spring wire arrangement method. Specifically, taking the elastic element as the second elastic element 23 and the second elastic element 23 having a split structure as an example, as shown in fig. 6B, in this modified embodiment, the second elastic element 23 includes a second entire outer contour 231, a second entire inner contour 232, and at least one second spring wire 233 extending between the second entire inner contour 231 and the second entire outer contour 232, wherein particularly, the second spring wire 233 extends from the circumferential direction of the second entire outer contour 231 and extends to the second entire inner contour 232 in a bending manner. Correspondingly, the second spring wire 233 comprises at least one second circumferential section extending in the circumferential direction of the second complete contour 231 and at least one second radial section extending in the radial direction of the second complete contour 231

Thus, by changing the extension of the second spring wire 233, the overall length of the second spring wire 233 can be maintained or even increased within a limited space. Accordingly, the degree of deformation of the second spring wire 233 is limited, wherein the degree of deformation of the second spring wire 233 is smaller as the length of the second spring wire 233 is longer, under the same stroke. That is, as the length of the second spring wire 233 is longer, the stroke of the motor 20 can be made longer with the same degree of deformation.

Fig. 6C illustrates a schematic view of yet another variant implementation of the first elastic element 22 or the second elastic element 23 of the motor 20 according to an embodiment of the present application. When the first elastic member 22 or the second elastic member 23 has a split structure, for example, in the example illustrated in fig. 1 and 2, the second elastic member 23 includes a third elastic part 234 and a fourth elastic part 235 separated from each other, a bridge 236 may be further provided between the third elastic part 234 and the fourth elastic part 235, as illustrated in fig. 6C, wherein the bridge 236 and a third half inner profile 2342 of the third elastic part 234 and a fourth half inner profile 2352 of the fourth elastic part 235 are integrally formed to connect the third elastic part 234 and the fourth elastic part 235, so that the uniformity during the installation of the second elastic member 23 may be improved.
