[0031] AA equipment (Active Alignment Equipment) is a high-precision automated device mainly used for the assembly and calibration of optical modules (such as camera modules, lens modules, etc.). Through active alignment technology, the device ensures the precise alignment between optical elements and image sensors, thereby improving imaging quality and optical performance. AA equipment mainly includes a machine table, an optical debugging system, a motion control module, high-precision motors and transmission devices, and an electrical connection module. Among them, the machine table provides overall support for the device and carries various motion platforms and fixed clamps. The optical debugging system includes a light source, an image sensor, and analysis software for real-time monitoring and analysis of alignment effects. The motion control module is used to control the movement and angle adjustment of the module. High-precision motors power the camera module through probes or other means to achieve functional debugging. The software control system is the core of automated control, and precise alignment and calibration operations are achieved through programming.

[0032] To improve the shooting performance of the camera module, precise adjustment of the deviation between its optical center and the image sensor is required, which is called AA process (Active Alignment). In the AA process, the camera module needs to be powered on with the AA equipment to ensure that the optical elements or actuators (such as voice coil motor VCM, optical image stabilization OIS, etc.) inside the camera module can work normally. In the powered-on state, the AA equipment realizes high-precision optical alignment by real-time electric control and adjustment of the camera module.

[0033] Please refer to Figures 1 to 2 The utility model embodiment provides a kind of camera module power device, for electrically connecting camera module 3 with AA equipment, this power device includes two oppositely arranged clamping components 1, limiting component 2 and drive component. Among them, limiting component 2 is vertically arranged between two clamping components 1, drive component is transmission connection with clamping component 1 and limiting component 2, for driving two clamping and pressing camera module 3 in AA process, avoid camera module 3 from shaking due to voice coil motor vibration, to cause probe contact badly.

[0034] Specifically, the clamping assembly 1 comprises a clamping part 11 and a first connecting part 12, the first connecting part 12 is arranged at one end of the clamping part 11 and below the clamping part 11, the limiting assembly 2 comprises a pressing part 21 and a second connecting part 22, the second connecting part 22 is arranged below the pressing part 21. In the working process of the camera module power-on device of the embodiment, first, the pressing part 21 is driven by the driving assembly to approach the camera module 3 and press the camera module 3, then the clamping part 11 and the first connecting part 12 are simultaneously driven by the driving assembly to approach the camera module 3. In this process, the clamping part 11 will contact the second connecting part 22 and further drive the second connecting part 22 to approach the camera module 3. When the clamping part 11 completes the clamping action, the probes of the first connecting part 12 and the second connecting part 22 respectively contact the electrical contact points (pin feet of the voice coil motor) at both ends and the side of the camera module 3, thereby realizing the multi-point power-on of the camera module 3, solving the problems of insufficient power-on contact points and unstable electrical contact in the prior art, and improving the stability of the camera module 3 in the AA process.

[0035] In order to ensure that the clamping action can stably and accurately drive the second connecting part 22 to electrically contact with the camera module 3, Figure 2 and Figure 3As shown, in this embodiment, the clamping portion 11 is provided with a driving block 111, and the second connecting portion 22 is provided with a guide surface 221 at both ends, which can provide stable path guidance for the movement of the driving block 111. Specifically, the driving block 111 can be wedge-shaped, and the corresponding guide surface 221 can also be a wedge-shaped chamfer structure. When the clamping portion 11 performs the clamping action under the driving of the driving assembly, the inclined surface of the driving block 111 and the inclined surface of the guide surface 221 are in contact with each other and produce a sliding action. During the contact process, when the clamping portion 11 is driven by the driving assembly to approach the camera module 3, the driving block 111 first starts to move along the guide surface 221 on the second connecting portion 22. Since the driving block 111 and the guide surface 221 are both wedge-shaped, the inclined surfaces thereof will produce close fitting and sliding action, which can ensure that the driving block 111 is always guided by the guide surface 221 during movement, avoiding the occurrence of deviation or irregular motion. Specifically, after the wedge-shaped inclined surface of the driving block 111 contacts the inclined surface of the guide surface 221, the movement of the driving block 111 gradually converts the horizontal clamping action displacement into a pushing force in the direction of the guide surface 221. The pushing force is stably transmitted to the second connecting portion 22 through the step-by-step contact of the wedge-shaped inclined surface. As the driving block 111 further slides, the second connecting portion 22 approaches the side electrical contact point of the camera module 3 along the predetermined path under the guidance of the guide surface 221. In this process, the contact area of the wedge-shaped inclined surface gradually increases with the movement of the driving block 111, ensuring uniform distribution of the pushing force. At the same time, the chamfer design of the guide surface 221 effectively reduces the frictional resistance of the driving block 111 during sliding, making the movement of the second connecting portion 22 more stable. When the driving block 111 completes the entire sliding stroke, the probe of the second connecting portion 22 is in precise contact with the electrical contact point (pin of the voice coil motor) on the side of the camera module 3, realizing electrical connection.

[0036] In the above embodiment, although the electrical connection between the second connecting portion 22 and the camera module 3 is achieved by arranging the driving block 111 and the guide surface 221, the connection between the second connecting portion 22 and the camera module 3 needs to be manually disconnected after the AA process is completed, which is complicated and not suitable for mass production. To solve this problem, in the present embodiment, a cavity 211 for accommodating the second connecting portion 22 is arranged on the pressing portion 21, and a guide rod 212 and a reset member are arranged in the cavity 211. The reset member is elastic, and its two ends are respectively in abutment with the cavity 211 and the second connecting portion 22. When the AA process is completed, the driving block 111 returns to the initial position under the control of the driving assembly, at which time the reset member releases the elastic restoring force and pushes the second connecting portion 22 back to the initial position along the direction of the guide rod 212, thereby automatically disconnecting the electrical connection with the camera module 3. Through the above structure, the automatic reset of the second connecting portion 22 is achieved, which meets the production requirements of automation and continuity in the AA process. At the same time, the guide rod 212 can provide stable movement guidance for the second connecting portion 22 during the reset process, thereby ensuring smooth and accurate movement during the reset process.

[0037] As shown in Figure 5 , the limiting assembly 2 further includes a second connecting probe 24 arranged on the second connecting portion 22. When the driving block 111 pushes the second connecting portion 22 to move along the guide surface 221 towards the camera module 3, the second connecting probe 24 contacts the electrical contact point (pin foot of the voice coil motor) of the camera module 3, thereby completing the electrical connection. In addition, the clamping assembly 1 further includes a first connecting probe 14 arranged on the first connecting portion 12. When the clamping portion 11 performs the clamping action, the first connecting probe 14 is driven by the clamping portion 11 to realize electrical connection with the corresponding electrical contact point (pin foot of the voice coil motor) of the camera module 3, thereby forming a stable multi-point power supply path.

[0038] In order to further improve the clamping stability of the clamping portion 11 to the camera module 3 and effectively limit the radial displacement of the camera module 3 during the clamping process, as shown in Figure 4 , in the present embodiment, the clamping portion 11 includes a main bonding portion 112 and a sub-bonding portion 113 arranged at both ends of the main bonding portion 112. The main bonding portion 112 and the sub-bonding portion 113 are arranged perpendicularly and together form a limiting area for limiting the radial displacement of the camera module 3. In actual operation, when the driving assembly drives the clamping portion 11 to clamp the camera module 3, one end of the camera module 3 is bonded to the main bonding portion 112, and the sub-bonding portion 113 contacts the two side surfaces of the camera module 3, thereby forming a three-point limiting structure. The limiting area effectively limits the radial displacement of the camera module 3 during the clamping process, ensures that the camera module 3 remains stable in the clamped state, and avoids the problem of poor electrical contact caused by radial displacement.

[0039] Preferably, the clamping assembly 1 comprises a first driving arm 13 connected to the clamping part 11 for transmitting the pushing force generated by the driving assembly to the clamping part 11 so as to drive the clamping part 11 to perform the clamping action; the limiting assembly 2 comprises a second driving arm 23 connected to the pressing part 21 for transmitting the pressing force generated by the driving assembly to the pressing part 21 so as to drive the pressing part 21 to apply the pressing force to the camera module 3. The driving assembly is in transmission connection with the first driving arm 13 and the second driving arm 23. When the driving assembly works, the pushing force is transmitted to the clamping part 11 through the first driving arm 13, so that the clamping part 11 clamps the camera module 3 and drives the first connecting part 12 to be electrically connected with the camera module 3. At the same time, the driving assembly transmits the pressing force to the pressing part 21 through the second driving arm 23, so that the pressing part 21 applies the pressing force to the camera module 3, thereby driving the second connecting part 22 to be electrically connected with the camera module 3, and realizing the multi-point electrical connection of the camera module 3.

[0040] In the embodiment, the first connecting probe 14 penetrates through the first connecting part 12 at both ends, so that one end of the first connecting probe 14 is in electrical contact with the electrical contact point (pin foot of the voice coil motor) of the camera module 3, and the other end is electrically connected with the AA device, thereby electrically connecting the camera module 3 with the AA device. At the same time, the second connecting probe 24 penetrates through the second connecting part 22 at both ends, so that one end of the second connecting probe 24 is in electrical contact with the electrical contact point (pin foot of the voice coil motor) of the camera module 3, and the other end is electrically connected with the AA device, thereby realizing the electrical connection between the second connecting part 22 and the camera module 3 and the AA device. In addition, in order to avoid current short circuit or miscontact, an insulating spacer 5 is arranged between the first connecting probe 14 and the first connecting part 12 and between the second connecting probe 24 and the second connecting part 22, so as to ensure that the electrical contact between the camera module 3 and the AA device is limited to the probe contact point, and the current does not flow to the first connecting part 12 and the second connecting part 22, thereby avoiding the risk of electric shock when the operator contacts the live device.

[0041] The utility model embodiment further provides an AA device, including machine table, connector and above -mentioned camera module live device, AA device passes through the connector 4 and is electrically connected with first connecting probe 14 and second connecting probe 24, and the connector can be led out from the machine table through wiring, and is not limited by distance, and is convenient to connect. Through the wiring, the connector can ensure the stable electrical connection between the first connecting probe 14 and the second connecting probe 24, thereby providing a reliable live path for the camera module 3.

[0042] Specifically, the driving assembly of the camera module live device is installed on the machine table. The machine table provides support and fixing effect, and ensures that the driving assembly can stably drive the clamping part 11 and the limiting assembly 2 when working, thereby clamping the camera module 3 and realizing electrical connection.

[0043] It should be noted that each embodiment in the specification adopts a progressive manner for description, and each embodiment focuses on the difference from other embodiments, and the same and similar parts between each embodiment can be referred to each other.

[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
