Description

Technical Field

[0002] The camera module is an electronic device that is crucial for image capture. The camera module is generally composed of a lens mount and a lens. As an assembly and testing industry, the camera module industry has complex production processes and large production capacity. A large number of defective products are also generated during the production of camera modules, which need to be repaired. The lens for module repair needs to go through a locking process, that is, locking the lens into the lens mount.

[0003] For example, a camera module lens locking fixture (Announcement No.: CN217669201U) includes a handle, a focusing head, an air pipe joint, an air pipe and a vacuum generator. The utility model is provided with a handle, a focusing head, an air pipe joint, an air pipe and a vacuum generator. The air pipe joint is connected to the vacuum generator through the air pipe. The vacuum generator is used to suck the air in the handle to form a negative pressure in the handle. When the person holds the handle and presses the vacuum button, the focusing head will suck up and fix the lens. After the lens is installed on the camera, the focusing head is rotated by the handle to lock the lens. The utility model designs a manual locking fixture to lock the repair module lens to reach the OK height. The focusing head is rotated. Due to the setting of the contraction amount, the module height will not change, thereby maintaining the consistent locking height of the module and the consistent repair height, thereby improving the repair yield rate and simultaneously reducing the movement of the focusing test, saving productivity and improving production efficiency.

At the same time, the control panel 13 will also configure the communication protocol and interface with the CCD camera 9 to ensure stable and fast data transmission between the two. When the lens enters the field of view of the CCD camera 9, the camera begins to capture the image, and the CCD image sensor inside it converts the optical signal into an electrical signal and generates image data. Since the CCD camera 9 has the characteristics of high resolution and high sensitivity, it can capture the precise position and details of the lens. The captured image data is transmitted to the control panel 13 through the preset communication interface. The control panel 13 receives the data and sends it to the control panel 13. Afterwards, the image is pre-processed using image processing software, such as noise reduction and contrast enhancement, to improve image quality. The control panel 13 applies visual positioning algorithms to analyze the pre-processed image. These algorithms can identify information such as the position, shape and size of the lens in the image. By matching with a preset template or model, the algorithm can determine the precise position of the lens. According to the results of the visual positioning algorithm, the control panel sends instructions to the translation component 2, the adjustment component 4 and the electric push rod 6, and then moves the positioning component 8 to the top of the lens to adsorb it. It can quickly identify the lens and automatically complete the locking process, greatly reducing the time and cost of manual operation, reducing manual intervention, and improving production efficiency.
