Recently, a screening conveyor has been put into use in the SMT production lines of several electronic manufacturing enterprises. This equipment, with its features of precise sorting, continuous conveying and high degree of automation, has effectively solved the problem of automatic separation of OK boards and NG boards (qualified products and defective products) in the production lines, and has become an important tool for improving quality control efficiency and reducing manual intervention. What is a screening conveyor?The screening conveyor is a specialized peripheral equipment for the SMT surface mount production line. Its main function is to automatically screen and sort PCB circuit boards during the production process. It uses sensors or receives signals from upstream equipment (such as AOI, SPI) to automatically send qualified boards to the main water line and direct defective boards into separate channels or designated storage boxes, achieving real-time control of production line yield and automatic material diversion.This equipment adopts a classic gray-green color industrial design. The upper part is equipped with multiple layers of Magazine storage racks, which can accommodate multiple PCBs simultaneously; the middle part is a green anti-static conveyor belt, and the lower part is equipped with a storage cabinet. The overall structure is compact and easy to move. Main features Precise filtering function: Supports automatic diversion of OK/NG signals, and can be connected to AOI, 3D inspection and other equipment signals.Multi-layer Magazine storage: The top stainless steel rack can store multiple circuit boards, enabling continuous operation.Green anti-static conveyor belt: The surface has moderate friction, protecting the PCB from being scratched or sliding.Intelligent control system: Equipped with a touch screen and button panel, supporting manual/automatic/online multiple modes.Stable structure: Bottom-mounted high-strength swivel wheels and fixed base cups ensure flexible movement and reliable positioning.User-friendly design: Lower double-door storage cabinet for convenient storage of common tools and spare parts. Core advantageCompared with traditional manual sorting, the screening conveyor significantly reduces the risk of human error and improves sorting efficiency and accuracy. It can effectively prevent defective plates from flowing into the downstream process, reduces repetitive labor, and simultaneously enhances the automation level of the entire line. According to the feedback from the using enterprises, after introducing this equipment, the manual configuration at the rear end of the production line can be reduced by 1-2 people, and the quality traceability is also more convenient. Typical application scenarios Automatic sorting at the end of AOI and SPI inspection equipment in the SMT production lineQuality control links in production lines for consumer electronics, automotive electronics, communication equipment, etc.Normal delivery of OK boards and isolation and buffering of NG boardsFlexible diversion requirements for small-batch, multi-variety mixed production lines The wide application of this screening conveyor demonstrates that the peripheral equipment of SMT is continuously evolving towards the direction of "intelligence and automation", providing a practical and efficient solution for electronic manufacturing enterprises to promote the construction of intelligent factories.

What is a Parallel Transfer Machine? The parallel transfer machine is a type of peripheral auxiliary equipment for SMT. Its main function is to horizontally transfer PCB boards between two parallel or adjacent conveying tracks. It can smoothly and accurately transfer the circuit boards output from the previous process to another parallel production line, achieving horizontal connection, avoidance or diversion of the production lines, without the need for large-scale layout adjustments of the entire workshop.Compared with traditional long-distance conveying lines, the parallel transfer machine has a smaller footprint. It usually adopts a modular design and can be easily moved and connected to different equipment, making it particularly suitable for modern SMT workshops with limited space. Main features  Precise lateral transfer: Utilizing high-precision rails and positioning systems, it ensures the PCB is transferred smoothly without any shaking, with low positioning errors, and effectively protects the components on the board.Intelligent control: Equipped with an industrial touch screen, it supports manual, automatic and online modes, and can be connected to the MES system to achieve real-time data interaction.Compact structure: The entire machine adopts a white industrial painted body, with multiple storage cabinets set below for convenient storage of common tools and spare parts; the bottom is equipped with swivel wheels for easy movement, and ground feet cups are used for stability when fixed.Safe and reliable: Equipped with three-color warning lights, emergency stop buttons, and anti-static transfer mechanisms, it complies with the safety and static protection requirements of the electronic manufacturing industry.High compatibility: Supports various PCB size ranges, and can quickly adjust the track width to meet the production needs of different products. Core advantage The most significant feature of this parallel transfer machine lies in enhancing the flexibility of the production line. When two soldering lines or inspection lines are arranged in parallel, it can quickly achieve the lateral transfer of the board pieces, avoiding the problems of space waste and excessively long transportation distances caused by traditional U-shaped or L-shaped return circuits. At the same time, it can also be used as a buffer zone, temporarily storing parts when the production line cycle times of the preceding and subsequent equipment do not match, thereby improving the overall production line utilization rate.According to feedback from the user, after introducing the parallel transfer machine, the adjustment time for the production line layout has been significantly shortened, and the space utilization rate has improved significantly. It is particularly suitable for mixed production modes of small and medium-sized board cards in fields such as mobile phones, automotive electronics, and medical equipment. Typical application scenarios Transferring boards laterally between multiple parallel SMT production linesFlexible connection between AOI inspection equipment, surface mounters and reflow soldering furnacesSituations where the material flow needs to be changed in the line optimization and renovation projectIntelligent scheduling in the high-mix production environment The launch of this parallel transfer machine provides electronic manufacturing enterprises with a cost-effective and high-return solution for optimizing production lines. As the construction of intelligent factories progresses, the flexible application of similar SMT peripheral auxiliary equipment is becoming an important direction for enhancing manufacturing efficiency.
