Description

Technical Field

[0001] The utility model relates to the technical field of camera modules, and more specifically, to a camera module for optimizing the coding level of two-dimensional codes. Background Art

[0002] In the field of production and manufacturing of camera modules, with the continuous progress of technology and the increasing maturity of production processes, market competition has become increasingly fierce. In order to ensure the stability of product quality and the improvement of production efficiency, major enterprises have been committed to optimizing production processes, reducing production costs, and increasing the qualified rate of products. In this context, it has become a standard practice in the industry to upload a two-dimensional code marking system for each camera module to achieve full-process tracking and monitoring. The two-dimensional code marking is usually arranged in the first position of the production process for subsequent production management and quality control. In most camera module designs, the two-dimensional code area is set at the position of the connector reinforcement plate because of its stable structure and easy identification. However, in the actual operation process, the two-dimensional code marking process at this position often faces challenges.

[0003] The traditional two-dimensional code marking area usually adopts a single-layer white ink structure design. The two-dimensional code information is engraved on the white oil on the reinforcement plate through laser engraving technology. However, this method has obvious limitations. On the one hand, when the laser power is too small or the engraving position is not flat, the two-dimensional code trace will be light, and the color difference is not obvious, which makes it difficult for the barcode scanner to accurately identify, affecting the scanning time and recognition success rate. On the other hand, too high laser power may cause the white oil to burn black, resulting in the two-dimensional code being completely unrecognizable. These problems not only increase the uncertainty in the production process but also seriously affect the production progress and product quality. Therefore, we make improvements and propose a camera module for optimizing the coding level of two-dimensional codes. Summary of the Utility Model

[0004] The technical problem to be solved by the embodiments of the utility model is that the two-dimensional code marking area usually adopts a single-layer white ink structure, which easily leads to the problem that the two-dimensional code laser engraving trace is light and difficult to identify.

[0005] To solve the above technical problem, the utility model adopts the following technical scheme:

[0006] A camera module for optimizing the coding level of two-dimensional codes includes: an FPC main body and an FPC reinforcement plate arranged on the FPC main body. A two-dimensional code marking area is arranged on the FPC reinforcement plate.

The black oil layer is used for laser engraving two-dimensional codes.

[0007] As an improved way of the utility model, an FPC connector is further arranged on the FPC main body.

[0008] As an improved form of the present utility model, a camera module body is provided on the FPC body. The camera module body includes a support frame and a chip mounted on the FPC body, and the chip is located inside the support frame.

[0016] Compared with the prior art, the embodiments of the present utility model mainly have the following beneficial effects:

[0017] To solve the problem that in the prior art, the QR code marking area usually adopts a single-layer white ink structure, which easily leads to light laser engraving traces of the QR code and difficulty in recognition, this application changes the original single-layer white oil structure to a double-layer ink structure design with white oil at the bottom and black oil on the surface.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this utility model. References to "embodiments" in this text mean that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this utility model. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] As described in the background art, the traditional two-dimensional code marking area usually adopts a single-layer white ink structure design. The two-dimensional code information is engraved on the white ink on the reinforcement board through laser engraving technology. However, this method has obvious limitations. On the one hand, when the laser power is too small or the engraving position is not flat, the trace of the two-dimensional code will be relatively light and the color difference will not be obvious, which will make it difficult for the barcode scanner to accurately identify, affecting the scanning time and recognition success rate. On the other hand, too high laser power may cause the white ink to burn black, resulting in the two-dimensional code being completely unrecognizable. These problems not only increase the uncertainty in the production process, but also seriously affect the production progress and product quality.

[0029] To solve this technical problem, the present utility model provides a camera module for optimizing the two-dimensional code marking level.

[0030] Specifically, please refer to Figures 1-4 , the camera module for optimizing the two-dimensional code marking level specifically includes:

[0031] An FPC main body 1 and an FPC reinforcement board 102 arranged on the FPC main body 1. A two-dimensional code marking area is arranged on the FPC reinforcement board 102. The two-dimensional code marking area adopts a double-layer ink, wherein the bottom layer of the double-layer ink is a white oil layer 2, and the surface layer is a black oil layer 201. The black oil layer 201 is used for laser engraving the two-dimensional code.

[0032] For the camera module for optimizing the two-dimensional code marking level provided by the present utility model, in this application, the original single-layer white oil structure is changed to a double-layer ink structure design with a white oil layer at the bottom and a black oil layer at the surface. Through this design, during the laser engraving process, the two-dimensional code is displayed in the color of the white oil in the black oil area, forming an obvious black and white contrast. This design not only reduces the requirements for the laser parameters and the flatness of the engraving position, improves the engraving trace of the two-dimensional code, but also significantly improves the level of the two-dimensional code, thereby shortening the scanning time and increasing the recognition success rate. In addition, this design also facilitates the tracking and analysis of defective modules, further improving the production efficiency and product quality.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0036] Embodiment 1 of the camera module for optimizing the QR code marking level of the utility model

[0037] Please refer to Figures 1-4 , the camera module for optimizing the QR code marking level of the utility model includes: an FPC main body 1 and an FPC reinforcing plate 102 arranged on the FPC main body 1. A QR code marking area is arranged on the FPC reinforcing plate 102, and the QR code marking area adopts double-layer ink. The bottom layer of the double-layer ink is a white oil layer 2, and the surface layer is a black oil layer 201. The black oil layer 201 is used for laser engraving the QR code; during the laser engraving process, the pattern of the QR code is engraved through the black oil layer 201 where the QR code is installed, and the QR code is displayed in the area of the black oil layer 201 in the color of the white oil layer 2, with an obvious black-and-white contrast, which well solves the problems of low QR code marking level and difficult scanning;

[0038] This application changes the original single-layer white oil structure to a double-layer ink structure design with a white oil layer at the bottom and a black oil layer on the surface. Through this design, during the laser engraving process, the QR code is displayed in the black oil area in the color of the white oil, forming an obvious black-and-white contrast. This design not only reduces the requirements for laser parameters and the flatness of the laser engraving position, improves the QR code laser engraving trace, but also significantly improves the level of the QR code, thereby shortening the scanning time and increasing the recognition success rate. In addition, this design also facilitates the tracking and analysis of defective modules, further improving production efficiency and product quality;

[0039] On the one hand, it reduces the requirements for laser parameters and the flatness of the laser engraving position, making the production process more stable and efficient. In actual production, there is no need to strictly control the laser parameters anymore, reducing the difficulty and time cost of equipment debugging. At the same time, the reduced requirement for the flatness of the laser engraving position also reduces the QR code quality problems caused by uneven laser engraving positions, improving the production yield. On the other hand, it improves the QR code laser engraving trace, making the QR code clearer and more durable. The obvious laser engraving trace is not only more eye-catching visually but also not easily worn and blurred during long-term use, ensuring the reliability of the QR code. In addition, it significantly improves the level of the QR code, shortens the scanning time, and increases the recognition success rate, bringing a more convenient and efficient use experience to users.

[0040] Furthermore, as Figure 4 shown, an FPC connector 101 is also arranged on the FPC main body 1, which greatly facilitates the connection with other devices. The setting of the FPC connector 101 enables the camera module to be quickly and stably connected to various devices without a complex wiring process, improving the convenience and flexibility of use.

[0041] Embodiment 2 of the camera module for optimizing the QR code marking level of the utility model

[0042] The camera module of the present utility model for optimizing the QR code coding level further, as Figure 3 shown, a camera module main body 3 is arranged on an FPC main body 1. The camera module main body 3 includes a support frame 301 and a chip 302 mounted on the FPC main body 1. The chip 302 is located inside the support frame 301. The support frame 301 is used for protecting the chip 302, effectively protecting the chip 302 from being damaged. The existence of the support frame 301 provides a stable installation environment for the chip 302, avoiding damage to the chip 302 due to external force extrusion, friction or other factors during use, and also extending the service life of the chip 302 and reducing the maintenance and replacement costs.

[0043] Further, as Figure 3 and Figure 4 shown, a double-sided adhesive 303 is pasted on the support frame 301. One side of the double-sided adhesive 303 away from the support frame 301 is connected to a lens holder 304. The double-sided adhesive 303 can connect the support frame 301 and the lens holder 304 together, providing a simple, fast and effective way for the connection between the support frame 301 and the lens holder 304. The double-sided adhesive 303 has good adhesiveness and adaptability, and can quickly and firmly connect the support frame 301 and the lens holder 304 together without using complex mechanical connection methods, saving assembly time and cost. At the same time, the softness of the double-sided adhesive 303 can also absorb vibrations and impacts to a certain extent, improving the seismic performance of the camera module.

[0044] Further, as Figures 2-4 shown, a threaded port 305 is opened on the lens holder 304. The inner wall of the threaded port 305 is threadedly connected to a lens main body 306. The lens main body 306 is connected to the lens holder 304 through the threaded port 305. By using threaded connection, focusing can be performed when the lens main body 306 is rotated to meet the requirements of different shooting distances and scenes. Threaded connection has high precision and stability, which can ensure the accuracy and reliability of focal length adjustment. At the same time, this connection method also makes the lens main body 306 not easy to loosen or shift during use, ensuring the stability of the shooting quality.

[0045] Further, as Figure 3 and Figure 4As shown, a protective cover 307 is connected to the side of the lens mount 304 away from the double-sided tape 303. The protective cover 307 can protect the lens body 306, extending the service life of the lens body 306. The protective cover 307 can effectively prevent the lens body 306 from being damaged by external factors such as dust, scratches, and collisions. During daily use, the protective cover 307 can block dust and impurities from entering the lens body 306, keeping the lens clean and improving the shooting quality. At the same time, in case of accidental collision or scratch, the protective cover 307 can play a buffering and protective role, reducing the risk of lens damage.

[0046] Further, as Figure 3 shown, a reinforcing member is provided between the support frame 301 and the FPC main body 1. The reinforcing member can achieve the firmness of the connection between the support frame 301 and the FPC main body 1.

[0047] Further, as Figures 1-3 shown, the reinforcing member is a reinforcing glue 308. The reinforcing glue 308 is connected between the FPC main body 1 and the support frame 301, and the reinforcing glue 308 can reinforce the connection between the FPC main body 1 and the support frame 301.

[0048] Embodiment Three of the Camera Module for Optimizing the QR Code Coding Level of the Present Utility Model

[0049] Further, a limiting member is provided between the FPC main body 1, the support frame 301, and the lens mount 304. The limiting member is used to limit the connection between the FPC main body 1, the support frame 301, and the lens mount 304, improving the stability of the connection between the FPC main body 1, the support frame 301, and the lens mount 304.

[0050] Further, as Figures 1-4 shown, the limiting member includes a first limiting plate 4 installed on the side of the FPC main body 1 away from the support frame 301. A plurality of second limiting plates 401 are fixedly installed on the top of the first limiting plate 4. The second limiting plates 401 are in contact with the sides of the support frame 301 and the lens mount 304. The first limiting plate 4 and the second limiting plates 401 cooperate with each other to limit the connection between the FPC main body 1, the support frame 301, and the lens mount 304, improving the stability of the connection between the FPC main body 1, the support frame 301, and the lens mount 304. The first limiting plate 4 and the second limiting plates 401 can limit the three components from different directions, ensuring that they do not displace in all directions. This precise limiting method can effectively resist the influence of external forces, improving the seismic performance and anti-impact performance of the camera module; at the same time, it also makes the assembly of the camera module more standardized and improves the production efficiency and product quality.
