Description

Technical Field

[0001] The utility model relates to a tray mechanism, in particular to a floating orientation mechanism for a robot loading tray. Background Art

[0002] With the acceleration of industrialization, automated production technologies are becoming increasingly prevalent, aiming to reduce the burden of manual labor and improve efficiency. Companies are gradually moving towards reducing manual intervention and even achieving unmanned operations. This trend has led to the development of numerous automated auxiliary equipment to meet production needs. However, the loading process for some columnar products still relies on manual positioning and loading, which is not only inefficient but can also affect the continuity and stability of the production process. Therefore, improving this process and implementing automated loading is crucial for improving overall production efficiency and reducing costs.

[0003] A Chinese patent discloses a rotary floating loader with an application number of CN202121710326.5, which includes a loader body bracket, on which a number of drive sprockets and driven sprockets are provided, and on which a transmission chain is correspondingly provided, a number of loading trays are provided, and the loader body bracket is provided with a gantry-type coarse positioning mechanism, a fine positioning mechanism, a floating loading mechanism, and a chip liquid recovery bucket for recovering the chip liquid corresponding to the loading tray in sequence, and the chip liquid recovery bucket is connected to a chip liquid return channel connected to the material processing water circulation system, which can better integrate the general loader with a separate fine positioning table. Although this design can accurately position the loader, the chip liquid needs to be recovered, which is prone to leakage during recovery, and at the same time increases the cost of use.
