Description

Technical Field

[0001] This invention pertains to auxiliary production equipment for circuit boards, specifically relating to an intelligent flexible production line for electronic component repair. Background Technology

[0002] After long-term operation, the number of faulty components on traditional subway vehicle circuit boards increases with the vehicle's age and operational intensity, typically ranging from a few to dozens per circuit board. Currently, the traditional desoldering and soldering methods for these faulty components mainly rely on manual operation, which has several drawbacks: First, it requires highly skilled operators, necessitating extensive professional training and practical experience to master the desoldering techniques, and skill differences can lead to inconsistent repair quality. Second, manual desoldering and soldering is inefficient and time-consuming, making it difficult to meet the demands of large-scale maintenance tasks, especially when dealing with a large number of faulty components, severely impacting vehicle maintenance progress. Third, manual desoldering and soldering is prone to quality problems such as incomplete soldering, missing solder, and uneven soldering, which can pose safety hazards and affect vehicle operational safety and reliability. Fourth, manual desoldering and soldering is physically demanding, requiring operators to work in confined spaces for extended periods, leading to fatigue. This traditional method is not only inefficient but also places high demands on the physical health and skills of the operators. Therefore, there is an urgent need to develop an intelligent and flexible production line for electronic component repair that can automate the desoldering and soldering of components, adapt to the repair needs of different types of circuit boards and faulty components, and improve the adaptability and flexibility of repair work.

[0041] Based on the above structure, the working principle of this embodiment is as follows: The electronic component to be repaired is aligned with the front clamping frame 1081 of the front-end electronic component quick clamping device 1080. After initial positioning by manual or mechanical means, the loading program is started via the front-end disassembly control display 1011. At this time, the built-in PLC control system receives the instruction and precisely controls the front-end positioning photoelectric sensor 1040 to emit a detection beam. When the sensor captures the signal that the electronic component has arrived at the loading area, it feeds back to the PLC. The PLC then drives the front-end conveyor belt servo motor 1035, whose rotational power is transmitted through the coupling, driving the front-end conveyor belt 1033 to smoothly transport the component to the large-view imaging station. After reaching the designated position, the PLC triggers the front-end large-view camera positioning device 1050, and the front-end large-view camera 1056 starts taking pictures under the stable support of the front-end large-view camera mounting bracket 1051. The front-end large-view camera plane supplement light 1052 lights up simultaneously, providing uniform and sufficient light to the shooting area, ensuring that the front-end large-view camera 1056 can obtain clear and accurate image information of the electronic component. After the image is captured, the image data is transmitted to the PLC in real time for analysis and processing to determine key data such as the precise location, shape, and size of the components to be disassembled on the electronic board. Based on the analysis results, the PLC precisely controls the front-end disassembly integrated robot 1070. The front-end robot 1072, supported by the front-end robot support column 1071, moves to the target position via its built-in six-axis movement, driving the front-end lead screw transmission device 1073. Simultaneously, the front-end pneumatic slider 1076 of the front-end lead screw transmission device 1073, guided by the front-end pneumatic slider fixing part 1075, carries the front-end telescopic cylinder connector 1170 and various actuators (such as the front-end vacuum suction device 1171, the front-end miniature electric gripper 1172, etc.) precisely to the disassembly point. The front-end small camera, fixed by the front-end small camera mounting bracket 1077, works with the front-end small camera planar fill light 1079 for precise local positioning, further confirming the component position and ensuring the accuracy of the disassembly operation. After precise local positioning is achieved via a front-end small camera planar fill light 1079 and fed back to the PLC, the upper and lower hot air guns automatically start after temperature adjustment according to the process temperature required for the corresponding board disassembly. Once the solder melts, the front-end vacuum suction device 1171 or the front-end miniature electric gripper 1172 is quickly switched to disassemble the designated components. After disassembly, the electronic board is simultaneously cleaned of residual solder paste in the holes by the front-end lower heating and desoldering device 1200. The front-end X-axis servo motor 1204 drives the front-end X-axis conveyor belt 1205, which, together with the front-end Y-axis servo motor 1203 driving the front-end Y-axis conveyor belt 1202, transports the board to the intermediate quality inspection station 2. At the intermediate quality inspection station 2, manual re-inspection is performed and the board is tested using a circuit board testing instrument 2002. The results are displayed in real time on the quality inspection status display 2003.Qualified boards enter the downstream electronic board quick clamping device 3060. The downstream disassembly control display 3011 starts the welding program. The PLC controls the downstream positioning photoelectric sensor 3040 to detect the board position. After feedback to the PLC, it drives the downstream conveyor belt servo motor 3035. The downstream conveyor belt 3033 is driven by the coupling to transport the board to the imaging station. The downstream wide-view camera 3056 takes pictures and positions the board under the support of the downstream wide-view camera mounting bracket 3051. The downstream wide-view camera plane supplement light 3052 provides supplementary lighting. The image data is transmitted to the PLC for analysis and processing to determine the welding point position. The PLC controls the integrated welding robot 3080 for the rear section. The rear robot 3082 moves the rear robot flange 3084 and the rear ball screw drive device 3083 to the target position. The rear pneumatic slider 3089, guided by the rear pneumatic slider fixing part 3085, carries the rear small vacuum suction device 3180, the rear pneumatic solder extruder 3181, the rear hot air gun 3182 and other components to the welding point. After the solder paste is automatically applied, the PLC controls the integrated welding robot 3080 to retrieve the required components from the rear electronic component material storage rack 3090. After returning to the designated position to place the components, the robot quickly cuts the rear hot air gun 3182 for curing. Subsequently, the rear flip drive motor 3072 drives the rear flip drive device 3070 to flip the plate to 180° with the rear clamp fixing frame connector 3071. The rear horizontal moving flip device 3030 adjusts the position to ensure precise docking of the welded components. After the welding of the components on both sides of the electronic board is completed, it is finally transported to the finished product area via the rear conveyor belt 3033.

[0042] In summary, this embodiment offers advantages in efficiency, precision, and convenience compared to traditional manual desoldering and soldering methods. In traditional repair models, the desoldering and soldering of electronic components primarily rely on manual operation, resulting in low efficiency, inconsistent quality, high labor intensity, and risks such as incomplete soldering and missed soldering. However, the structure of this embodiment, utilizing high-resolution vision systems at both the front and rear ends, can quickly and accurately locate components, guiding the robot to automate disassembly and soldering operations, effectively shortening the repair cycle and improving production efficiency. Simultaneously, the equipment is easy to operate, requiring only simple training to master, significantly reducing labor costs and intensity, minimizing human error, and enhancing the stability and safety of repair work. This provides a new intelligent and automated solution for the electronic component repair field, powerfully driving technological progress in the industry.
