Description

Technical Field

[0001] This utility model relates to the field of plasma processing technology, and in particular to a rotating atmospheric plasma processing auxiliary device. Background Technology

[0002] The peripheral balloon dilation catheter is quite long and cannot be further processed in low-pressure plasma treatment equipment with limited capacity. Therefore, a rotating atmospheric plasma treatment equipment was selected for localized treatment of the bonding area. This process requires manual operation, which wastes labor costs and workflow time to some extent. Furthermore, the variability introduced by manual processing poses a certain risk to the bonding effect.

[0003] Patent CN201811388664.4 from Nanjing Perspet Electronics Technology Co., Ltd. discloses a direct-drive atmospheric low-temperature rotary plasma treatment machine and its operating method. This machine allows adjustment of the height and angle of the corresponding low-temperature plasma nozzle according to the shape of the polymer material workpiece, positioning the material processing surface at an appropriate distance from the nozzle. However, this patent focuses on the self-adjustment of the plasma equipment, neglecting the human intervention during workpiece processing.

[0004] Xi'an University of Electronic Science and Technology's patent CN202410638144.3 discloses a device for cleaning stainless steel electrodes using atmospheric pressure plasma, comprising a plasma generator and a cleaning platform. The cleaning platform is a movable base with guide rails, used to support either the plasma generator or the stainless steel electrode to be cleaned. The cleaning platform 5, being a movable base with guide rails, possesses certain high-temperature resistance. Its function is to enable relative movement between the plasma generator and the stainless steel electrode to be cleaned. However, this device can only mount either the plasma generator or the stainless steel electrode to be cleaned onto the movable base.

[0005] Therefore, in order to uniformly process tubes of different sizes, there is an urgent need for an auxiliary device for a rotating atmospheric plasma treatment equipment that saves manpower, allows for the replacement of mandrels of different sizes, has adjustable distance and processing range, and avoids processing differences.
