Technical Field

[0001] The utility model relates to the technical field of assembly machines, in particular to an automatic valve assembly machine. Background Art

[0002] The valve automatic assembly machine is a mechanical equipment, which is mainly used to automatically assemble and assemble the various components of valve products, such as valve body, valve disc, valve stem, handle, etc., according to the predetermined process flow and assembly sequence, through automated mechanisms and systems, to finally form a complete valve product. The valve automatic assembly machine usually adopts advanced technologies such as robot technology, sensor technology, and automatic control technology to realize an automated, efficient, and high-quality valve assembly process. It can greatly improve production efficiency, reduce labor costs, reduce production costs, and ensure product quality and consistency. At the same time, the valve automatic assembly machine can also effectively avoid the influence of human factors on product quality and improve product reliability and safety.

[0003] At present, the automatic valve assembly machines on the market usually include a multi-station turntable. The multi-station turntable is a mechanism in the automatic valve assembly machine. It can complete multiple assembly steps or actions at the same time during a working process. By concentrating multiple assembly stations on the same turntable, the multi-station turntable can realize efficient and fast valve assembly. Specifically, the multi-station turntable can include multiple assembly stations, feeding mechanisms, detection mechanisms, operating mechanisms, etc., and can be equipped with other auxiliary mechanisms as needed. During the assembly process, the turntable will rotate according to a preset program, and each assembly station will be coordinated with the operating mechanism, feeding mechanism, etc. in sequence to complete a series of assembly actions. The application of the multi-station turntable can improve the efficiency and accuracy of valve assembly, reduce manual intervention and operation time, and reduce production costs. When the multi-station turntable in the prior art rotates, the valve body placed on the turntable will shake slightly, which will cause the valve body to deviate to a certain extent, making it impossible for other operating mechanisms to align the valve body with other parts.
