Description

Technical Field

[0001] The present invention relates to the technical field of camera modules, and in particular to an auto-focus camera module structure with variable shading and windowing. Background Art

[0002] Camera modules are crucial electronic components for image capture. Simply put, they convert optical signals from objects into digital signals that can be read and stored. They primarily consist of components such as a lens, image sensor, drive motor / base, IR filter, and circuit board. While the lens focuses light onto the image sensor, the IR filter removes unwanted light. However, once light enters the module, it still strikes other reflective surfaces, such as gold bonding wires and components. Currently, the conventional method is to apply light-shielding ink to the IR filter to control the window size. However, due to tolerances in the IR filter's screen printing ink, base assembly mounting tolerances, image sensor mounting tolerances, and outward lens movement during close-up focusing, stray light is a common problem.

[0003] With the increasing number of camera modules, large-display sensors, and ultra-high-pixel image sensors, the requirements for light shielding dimensions are becoming increasingly stringent. Some manufacturers have adopted a method of increasing the silkscreen size on one side of the IR filter after optical path simulation. However, solutions that rely on a fixed light shielding dimension require multiple verifications when stray light occurs, which is time-consuming and labor-intensive. Summary of the Invention

[0004] Based on this, it is necessary to provide an autofocus camera module structure with variable shading window opening to address the above technical problems. A movable window opening component is added inside the camera module, and the movable window opening component is installed between the image sensor and the IR filter. There is no need to add silk screen printing on the IR filter. When the motor drives the optical lens to focus, the movable window opening component receives the signal to synchronously adjust the size of the window opening to prevent light from irradiating the gold wire.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0020] As described in the background technology, existing camera modules use a single-side IR filter size that is additionally enlarged by the silk-screen size after optical path simulation to control the window size. However, this solution, which relies on a fixed shading size, requires multiple verifications when stray light occurs, which is time-consuming and labor-intensive.

[0021] In order to solve this technical problem, the present invention provides an automatic focus camera module structure with variable shading window. By adding a movable window assembly 7 inside the camera module and installing the movable window assembly 7 between the image sensor 2 and the IR filter 3, there is no need to add silk screen printing on the IR filter 3. When focusing, the movable window assembly 7 receives a signal to synchronously adjust the size of the window 9 to prevent light from irradiating the gold wire 10. Then the image sensor 2 receives the light introduced from the lens assembly 5 and filtered through the IR filter 3. Since the movable window assembly 7 is adjusted in real time to a window size without dark corners and stray light according to the photosensitive area of ​​the image sensor 2, excess reflected light can be reduced to avoid dark corners or stray light.

When the lens assembly 5 is focused, the movable window assembly 7 receives a signal to synchronously adjust the size of the window 9.

[0023] The variable shading window auto-focus camera module structure provided by the present invention adds a movable window assembly 7 inside the camera module, and installs the movable window assembly 7 between the image sensor 2 and the IR filter 3. There is no need to add silk screen printing on the IR filter 3. When focusing, the movable window assembly 7 receives a signal to synchronously adjust the size of the window 9 to prevent light from irradiating the gold wire 10. Then the image sensor 2 receives the light introduced from the lens assembly 5 and filtered by the IR filter 3. Since the movable window assembly 7 is adjusted in real time to a window size without dark corners and stray light according to the photosensitive area of ​​the image sensor 2, it can reduce excess reflected light, avoid dark corners or stray light, and improve the imaging effect.

[0027] Example 1 Please refer to Figure 1-7 A variable light-shielding windowed autofocus camera module structure includes a circuit board 1, an image sensor 2, an IR filter 3, a base 4, and a lens assembly 5. The image sensor 2 and base 4 are mounted on the upper surface of the circuit board 1, the IR filter 3 and the lens assembly 5 are mounted on the upper surface of the base 4, and a light window 6 is formed on the base 4. The light window 6 is used to direct light in the lens assembly 5 toward the photosensitive area of ​​the image sensor 2. Movable window assembly 7, metal lead 8 and gold wire 10, the movable window assembly 7 is installed between the image sensor 2 and the IR filter 3, the two ends of the metal lead 8 are electrically connected to the movable window assembly 7 and the circuit board 1 respectively, the two ends of the gold wire 10 are electrically connected to the image sensor 2 and the circuit board 1 respectively, a window 9 is provided on the movable window assembly 7, when the lens assembly 5 is focused, the movable window assembly 7 receives the signal to synchronously adjust the size of the window 9, the gold wire 10 is located on the lower side of the movable window assembly 7, and the size of the window 9 is reduced to prevent light from shining on the gold wire 10.

[0028] The variable shading window auto-focus camera module structure provided in this embodiment adds a movable window assembly 7 inside the camera module and installs the movable window assembly 7 between the image sensor 2 and the IR filter 3. There is no need to add silk screen printing on the IR filter 3. When in use, the driver chip on the circuit board 1 transmits a signal to the motor 502 through the circuit. The motor 502 drives the optical lens 501 to focus and transmits the signal to the first piezoelectric motor 703 and the two second piezoelectric motors 704 of the movable window assembly 7 at the same time. At this time, the first piezoelectric motor 703 and the second piezoelectric motor 704 The first movable light-shielding component 705 and the second movable light-shielding component 706 are respectively moved to adjust the size of the window 9, so that when the motor 502 drives the optical lens 501 to focus, the movable window assembly 7 receives the signal and synchronously adjusts the size of the window 9 to prevent light from irradiating the gold wire 10. Then the image sensor 2 receives the light introduced from the lens assembly 5 and filtered by the IR filter 3. Since the movable window assembly 7 is adjusted in real time to a window size without dark corners and stray light according to the photosensitive area of ​​the image sensor 2, it can reduce unnecessary reflected light, avoid dark corners or stray light, and improve the imaging effect.

[0029] Example 2 The structure of the variable shading and windowed auto-focus camera module provided in Example 1 is further optimized. Specifically, Figure 3-6As shown, the movable window opening assembly 7 includes an annular fixed frame 701, two first piezoelectric motors 703 and two second piezoelectric motors 704, the two first piezoelectric motors 703 are respectively fixedly connected to the left and right sides of the lower surface of the annular fixed frame 701, and the two second piezoelectric motors 704 are respectively fixedly connected to the front and back sides of the lower surface of the annular fixed frame 701, the output end of the first piezoelectric motor 703 is fixedly connected to the first moving light-shielding component 705, and the output end of the second piezoelectric motor 704 is fixedly connected to the second moving light-shielding component 706, the first piezoelectric motor 703 and the second piezoelectric motor 704 are respectively used to drive the first moving light-shielding component 705 and the second moving light-shielding component 706 to move and adjust the size of the window 9; The first piezoelectric motor 703 and the second piezoelectric motor 704 are stick-slip piezoelectric motors with adjustable voltage. The working principle of the stick-slip piezoelectric motor is as follows: it consists of a piezoelectric stack of piezoelectric materials fixed on one side to generate greater displacement and force, a contact, a moving part and a bearing; In the sticking stage, due to the slow increase in voltage, the piezoelectric material slowly extends, and due to the friction between the contact point and the slider, the slider moves with the contact point. Then, by applying a rapidly decreasing voltage, the piezoelectric actuator is quickly retracted. The slider remains stationary due to inertia, while the contact point slides back to its original position. By repeating these two steps, macroscopic motion can be achieved. When it stretches slowly, the friction force drives the slider to move together, and the piezoelectric material quickly retracts. The slider does not move due to inertia, and the piezoelectric material continues to stretch slowly, driving the slider to continue moving. like Figure 6 As shown, avoidance grooves 707 are provided on the left and right sides of the upper surface of the second moving light-shielding component 706, and the front and rear ends of the first moving light-shielding component 705 extend into the interior of the avoidance grooves 707. The upper surfaces of the annular fixed frame 701, the first moving light-shielding component 705 and the second moving light-shielding component 706 are flush; in this way, the two first moving light-shielding components 705 and the two second moving light-shielding components 706 form a rectangular structure. When the size of the window 9 is adjusted, the first moving light-shielding component 705 slides in the avoidance grooves 707 of the second moving light-shielding component 706. At this time, the first moving light-shielding component 705 and the second moving light-shielding component 706 move toward the middle of the annular fixed frame 701, and the size of the window 9 is adjusted by blocking by the first moving light-shielding component 705 and the second moving light-shielding component 706. like Figure 6As shown, there are eight metal leads 8, which are divided into four groups. The four groups of metal leads 8 are respectively installed on the front and rear sides and the left and right sides of the annular fixing frame 701. One end of the metal lead 8 extends to the outside of the base 4. The annular fixing frame 701 is provided with metal pins connected to the first piezoelectric motor 703 and the second piezoelectric motor 704. The base 4 is provided with metal pins connected to the circuit board 1. The metal leads 8 are connected to the metal pins on the base 4 and the metal pins of the movable window assembly 7 by ACF glue. When in use, the opening window 9 of the movable window assembly 7 is initially sized after optical path simulation or directly preset parameters on the machine. When the camera module is powered on, the window size is adjusted in real time according to the photosensitive area of ​​the image sensor 2 to a size without dark corners and stray light. When the movable window assembly 7 is powered off, the size of the opening window 9 will not change.

[0030] Example 3 The structure of the variable shading and windowed auto-focus camera module provided in Example 1 or 2 is further optimized, such as Figure 3-5 As shown, a first groove 401 is provided on the lower surface of the base 4, and the movable window assembly 7 is installed on the inner wall of the first groove 401. An annular light shielding plate 702 is installed between the annular fixed frame 701 and the inner wall of the first groove 401. The annular light shielding plate 702 is used to block the gap between the annular fixed frame 701 and the first movable light shielding component 705 and the second movable light shielding component 706; a second groove 402 is provided on the upper surface of the base 4, and the IR filter 3 is installed in the inner cover of the second groove 402 through the first adhesive 403; the annular fixed frame 701 and the annular light shielding plate 702 are fixedly connected to the inner wall of the first groove 401 to prevent light from passing through the gap. When the two first movable light shielding components 705 and the two second movable light shielding components 706 move, the gap between them and the annular fixed frame 701 can be blocked by the annular light shielding plate 702 to prevent light leakage.

[0031] Example 4 The structure of the variable shading and windowed auto-focus camera module provided in the above embodiments is further optimized, such as Figure 1 and Figure 3 As shown, the circuit board 1 includes a PCB board 101, a module FPC 102 and a connector 103. A capacitor and a driver chip are installed on the PCB board 101. One end of the module FPC 102 is electrically connected to the PCB board 101, and the other end of the module FPC 102 is electrically connected to the connector 103. A second adhesive member 104 is installed between the lower surface of the base 4 and the PCB board 101; the driver chip transmits a signal to the motor 502 through the circuit, and the motor 502 drives the optical lens 501 to focus. At the same time, the signal is transmitted to the first piezoelectric motor 703 and the two second piezoelectric motors 704 of the movable window assembly 7, thereby controlling the size of the window; like Figure 1 and Figure 3 As shown, the lens assembly 5 includes an optical lens 501 and a motor 502. The optical lens 501 is used to converge or disperse incident light, and the motor 502 is used to drive the optical lens 501 to focus. A third adhesive 503 is installed between the lower surface of the motor 502 and the base 4; the first adhesive 403, the second adhesive 104 and the third adhesive 503 are all annular structures; the light entering the optical lens 501 is incident on the inside of the module, and then the image sensor 2 receives the light introduced from the lens assembly 5 and filtered by the IR filter 3. The first adhesive 403, the second adhesive 104 and the third adhesive 503 improve the sealing to prevent light from entering the inside of the module.

[0032] The use process of the variable shading and windowed auto-focus camera module structure provided by the present invention is as follows: By adding a movable window assembly 7 inside the camera module and installing the movable window assembly 7 between the image sensor 2 and the IR filter 3, there is no need to add silk screen printing on the IR filter 3. When in use, the driver chip on the circuit board 1 transmits a signal to the motor 502 through the circuit. The motor 502 drives the optical lens 501 to focus and transmits the signal to the first piezoelectric motor 703 and the two second piezoelectric motors 704 of the movable window assembly 7. At this time, the first piezoelectric motor 703 and the second piezoelectric motor 704 respectively make the first moving light shielding component 70 5 and the second movable light-shielding component 706 move to adjust the size of the window 9, so that when the motor 502 drives the optical lens 501 to focus, the movable window assembly 7 receives the signal and synchronously adjusts the size of the window 9 to prevent light from irradiating the gold wire 10. Then, the image sensor 2 receives the light introduced from the lens assembly 5 and filtered by the IR filter 3. Since the movable window assembly 7 is adjusted in real time to a window size without vignetting and stray light according to the photosensitive area of ​​the image sensor 2, it can reduce unnecessary reflected light, avoid vignetting or stray light, and improve the imaging effect.
