TECHNICAL FIELD

[0002] On a micro-assembly automatic production line, a meandering flow body track is widely used for circulating conveying of carriers between stations. Such a system is often used in the assembly process of high-density, multi-tact electronic devices, precision components or sensing components, and has the characteristics of small carrier size, fast conveying tact, and compact track layout. Since the carriers continuously run on the track, it is easy to cause rear-end accumulation at the turning section, control node or station, especially when the carrier passes through the control structure such as the baffle and the positioner, the rear carrier often closely adheres to the front carrier due to inertia or out-of-control scheduling, causing problems such as carrier interconnection, positioning failure, tact disorder and even hardware collision.
[0003] To solve the above problems, the existing technology usually adopts a "multi-section short belt + photoelectric sensor" structure to divide the track into multiple control sections, and to start or stop the corresponding belt section by detecting the carrier position, so as to realize physical separation control. However, this scheme has the following disadvantages: first, the structure is complex and the cost is high: each belt section needs to be independently configured with a drive motor, a sensor and a control module, and the overall investment is large; second, poor adaptability: this structure is not suitable for micro systems with closed tracks or limited space, and is difficult to deploy flexibly; third, large maintenance amount and high risk of misjudgment: the sensor is easily disturbed by light, and troubleshooting and replacement are tedious, which easily affects the tact; fourth, rigid control strategy: the separation control depends on the sensor judgment, and there is no intelligent linkage or action foresight, and the response is lagging.
