Description

Technical Field

[0001] The utility model relates to the technical field of actuators, in particular to a voice coil linear rotary actuator. Background Art

[0002] At present, there are some ZR actuators with adsorption function. The output shaft of this type of actuator can not only perform translational and rotational movements, but can also be connected to a vacuum device through an air pipe, so that the vacuum device can provide adsorption force for the output shaft, enabling the output shaft to adsorb and release the carried object.

[0003] However, in the existing ZR actuator with adsorption function, the air channel of the output shaft is directly connected to the vacuum device through an external air pipe. During the operation of the ZR actuator, the output shaft will move, causing the external air pipe connected to the output shaft to be easily swung and pulled by the output shaft. The external air pipe is generally long, and during the process of being swung and pulled, it is easy to have problems of excessive local force, which makes the external air pipe easily damaged, affecting the normal use of the ZR actuator.

[0004] A utility model disclosed in Chinese Patent Publication No. CN219866128U proposes a ZR actuator in which the external vacuum device is connected to an air port on the housing. During operation, the housing does not move or rotate, preventing the external air pipe from being swung or pulled. This reduces damage to the external vacuum device, extending its service life. Furthermore, the distance between the air port on the housing and the output shaft is relatively short. The internal air pipe, newly added within the housing in this embodiment, is less susceptible to significant localized pulling forces during output shaft movement, thus minimizing damage. Inspired by this, the present utility model addresses the issue of external air pipe damage, which can affect the normal operation of the ZR actuator. By providing a voice coil linear-rotary actuator, this invention addresses the issue of easily damaged external air pipes. Utility Model Content
