Description

Technical Field

[0002] With the continuous advancement and innovation of science and technology, various product styles are becoming more and more diverse and electronic products are becoming more miniaturized. The spacing between products is becoming closer and closer. The demand for mutual coordination between components is increasing sharply. The space utilization between products has also reached an unprecedented level of closeness. Since the tray has become an indispensable core component to ensure the accurate storage and positioning of various products, its role in the efficient production process is becoming increasingly prominent. Therefore, a simple and reliable tray unloading mechanism has become the key to ensure the smooth operation of the production line;

[0003] The existing tray unloading system is constrained by its huge structural framework, too many mechanical components and the complexity of the internal structure. These features not only reduce the stability of the system, but also pose a challenge to the accuracy of the tray positioning, and are not flexible and convenient in adjustment and setting. The most prominent problem is that most of these devices cannot effectively cope with the diverse positioning needs of multiple trays. Once the tray needs to be switched between multiple positions, accurate positioning becomes a problem, and it has to rely on multi-step coordinated operations to gradually approach the goal. In summary, the current tray unloading mechanism is relatively redundant and lacks universal compatibility. Not only is the assembly process cumbersome, but the debugging process is also particularly time-consuming and labor-intensive. This model is not only inefficient, but also consumes a lot of resources, including human resources and material costs. Utility Model Content
