Description

Technical Field

[0001] This utility model relates to the field of solder inspection technology, and in particular to an integrated visual solder inspection machine. Background Technology

[0002] With the continuous development of the electronics manufacturing industry, especially with the popularization of smart hardware and consumer electronics products, the demand for circuit board soldering is increasing. As a key connection method in electronic products, the accuracy and efficiency of soldering directly affect the quality of products and production costs. In the traditional soldering process, especially when soldering circuit boards of different sizes and shapes, the adaptability of soldering equipment and the flexibility of operation are particularly important. In order to improve production efficiency and ensure soldering quality, modern soldering equipment is gradually developing towards automation and intelligence. Among them, the vision soldering inspection integrated machine has emerged. By integrating soldering functions and inspection mechanisms, combined with high-precision cameras and lighting equipment, it can not only achieve precise soldering of circuit boards, but also perform efficient quality inspection of circuit boards after soldering, meeting the production needs of circuit boards of different sizes, and at the same time greatly improving the automation level of the production line.

[0003] Existing solder testing equipment typically employs independent soldering and testing devices. These devices generally consist of independent mechanical and control structures. In the soldering section, traditional techniques often use robotic arms in conjunction with customized fixtures to fix the circuit board, and drive the solder head via pneumatic drive or servo motor to perform the soldering operation.

[0004] A prominent problem with existing technologies is that when circuit board sizes are inconsistent, existing equipment often struggles to perform precise soldering. Different sized circuit boards require different solder supports and solder head positions. Traditional soldering equipment typically requires manual adjustment of relevant parameters or replacement of equipment components when handling circuit boards of various sizes, resulting in low production efficiency and a high risk of misoperation. This problem is particularly severe when dealing with large-scale production and multiple circuit board models, affecting soldering accuracy and reducing the automation level of the equipment, making it difficult to achieve efficient and precise soldering. To address this issue, a vision-based solder inspection integrated machine is proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 4 An embodiment of this utility model is provided: a visual soldering inspection integrated machine includes a chassis 1, a controller 6 is fixedly connected inside the chassis 1, a soldering device 7 is fixedly connected inside the controller 6, and a soldering component is provided at the bottom of the controller 6. The soldering component is used to perform soldering operations on the circuit board.

[0026] The soldering assembly includes a solder bracket 8 and a solder head 5. The solder bracket 8 is slidably connected to the bottom of the controller 6, providing flexible soldering operation space. The solder head 5 is fixedly connected to the bottom of the solder bracket 8, responsible for precise soldering to ensure solder joint quality. A desoldering box 4 is fixedly connected inside the chassis 1 for drying after soldering, ensuring solder solidification and removing excess residue. A slide rail 3 is fixedly connected to the top of the chassis 1, and a sliding plate 21 is slidably connected to the slide rail 3. The movement of the sliding plate 21 allows the circuit board to be positioned in the soldering area. A display screen 2 is fixedly connected to the outer wall of the chassis 1 to display the real-time working status of the equipment and the soldering process, facilitating operator monitoring. A bracket frame 15 is fixedly connected inside the controller 6, and a camera component is installed inside the bracket frame 15. The camera component is used to automatically detect the soldering quality of the circuit board after soldering. The camera component captures images of the circuit board surface and transmits them to a data terminal for analysis, thereby ensuring that the soldering meets quality standards.

[0027] Specifically, when using the integrated visual soldering inspection machine, the circuit board to be soldered is first placed on the sliding plate 21 to ensure accurate positioning. Then, by starting the drive device, the belt drive wheel 11 is rotated. The belt drive wheel 11 drives the solder support 8 to move smoothly. The movement of the solder support 8 then drives the solder head 5 to precisely solder the pads on the circuit board, ensuring the quality and precision of each solder joint. After soldering is completed, the device automatically starts the tin blowing box 4 to dry the soldered circuit board, helping to accelerate solder solidification and prevent overheating or excessive residue. The entire process is achieved through the linkage of the above structures, transforming circuit board soldering from manual operation to an automated process. The device has a high degree of automation and strong adaptability, and can quickly process circuit boards of different specifications and sizes. It not only improves production efficiency but also effectively reduces errors caused by manual operation. By precisely controlling factors such as temperature, time, and pressure during the soldering process, the quality of the solder and the stability of the solder joints are ensured, greatly improving the precision and reliability of the soldering, thereby meeting the needs of modern electronic products for high-precision and high-efficiency soldering processes.

[0028] Reference Figure 1 - Figure 4The imaging assembly includes a camera 18 and a lens 13. The side wall of the camera 18 is fixedly connected to the side wall of the bracket frame 15 to ensure the stability of the camera 18 and to effectively capture images of the circuit board surface. The top of the lens 13 is fixedly connected to the bottom of the camera 18, providing a clear imaging angle for precise imaging of the soldering area. A belt drive pulley 11 is provided on the top of the controller 6. A lead screw 9 is fixedly connected to the output end of the belt drive pulley 11. The lead screw 9 is used to drive the rotation of the belt drive pulley 16, thereby controlling the precise positioning of the imaging assembly and ensuring that the shooting angle and position of the camera 18 meet the requirements. One end of the lead screw 9 is fixedly connected to the output end of the belt drive pulley 16 to achieve precise camera adjustment. A solder feeder 19 is fixedly connected to the outer wall of the controller 6. The solder feeder 19 is used to accurately deliver solder to the soldering point to ensure appropriate and even distribution of solder. A motor protective cover 20 is fixedly connected to the outer wall of the controller 6 to provide motor protection, preventing dust and other external substances from entering and ensuring normal motor operation. A camera displacement cylinder 17 is installed inside the controller 6. This cylinder achieves precise displacement of the camera 18, ensuring accurate alignment of the shooting angle and the circuit board. A spotlight 14 is fixedly connected to the controller 6. The spotlight 14 is used to provide uniform illumination, improve the visibility of solder and circuit board surfaces, and ensure clear images. A fan 22 is installed inside the controller 6. The fan 22 is used to dissipate heat from the inside of the chassis 1, maintain a stable operating temperature of the equipment, and prevent overheating. A servo motor 10 is fixedly connected to the side wall of the controller 6. The servo motor 10 drives various mechanical components to ensure precise operation and movement. A connecting column 12 is slidably connected inside the controller 6. The connecting column 12 is used to connect and support other mechanical components inside the controller 6, enhancing the overall structural stability of the equipment.

[0029] Specifically, after the circuit board soldering is completed, to ensure soldering quality, the first step is to turn on the lighting lamp 14, using its strong light source to project uniform light onto the circuit board surface, providing comprehensive illumination for the solder quality. The light from the lighting lamp 14 not only effectively eliminates shadows on the circuit board surface but also highlights the details of the solder joints, making the soldering area more clearly visible. Next, the camera displacement cylinder 17 is activated, driving it to precisely move the camera 18. Through the meticulous adjustment of the camera displacement cylinder 17, the camera 18 can be precisely aligned vertically with the circuit board surface, ensuring that the captured image accurately reflects the surface condition of the circuit board. After the camera 18 takes the picture, the image information is quickly transmitted to the data terminal for processing and analysis. Through this series of precise automated steps, the solder quality on the circuit board can be efficiently and error-free, ensuring that the quality of each solder joint meets the predetermined standards. This inspection process not only improves the efficiency of inspection but also significantly reduces human error, ensuring the stability and reliability of the soldering process, thereby providing a strong guarantee for the final product quality of the circuit board.

[0030] Working principle: When using the integrated visual soldering inspection machine, the circuit board to be soldered is first placed on the sliding plate 21. Then, the drive belt pulley 11 is activated, which moves the soldering bracket 8. The movement of the soldering bracket 8 in turn drives the soldering head 5 to solder the solder board placed on the sliding plate 21. Finally, the desoldering tube 4 is activated to dry the soldered solder board. Through the linkage of the above structure, the circuit board is soldered. The above process automates the circuit board soldering process, making it highly adaptable. The process is fast and efficient, mainly using automated equipment, and has high precision in soldering. After the circuit board is soldered, the light from the light lamp 14 is turned on and projected onto the circuit board. Then, the camera displacement cylinder 17 is activated to move the camera 18 so that the camera 18 is aligned with the circuit board. Then, the camera displacement cylinder 17 takes a picture and transmits the image information to the data terminal, thereby achieving the purpose of inspecting the soldered circuit board and meeting the required standards.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
