Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to the field of IPC A61C13, and more particularly relates to an omnidirectional UV LED curing system with a 360-degree angle on the outer surface of a tubular object.
Background
Some medical devices require a hydrophilic coating on the outer surface, ultraviolet light curing of the hydrophilic coating is a widely used technique. If the surface of the medical device coated with the hydrophilic coating cannot be completely irradiated by ultraviolet light in the curing process or the ultraviolet light energy absorbed by the surface is uneven, the adhesive strength between the hydrophilic coating and the substrate material can be affected, and the product is poor. The more light energy from the light source is irradiated to the surface of the equipment during the irradiation curing process, the higher the efficiency of the light source, the higher the curing efficiency and the faster the curing speed.
However, the conventional surface light source irradiation method can cause great waste of energy for equipment with smaller surface area. The single-sided area light source irradiates, the equipment faces one side of the light source, and the absorbed light energy is far more than one side facing away from the light source. Under the condition, to ensure uniform irradiation, only the irradiated object can be rotated, or the light source can be rotated around the irradiated object, so that the difficulty of operation can be increased, and the cost of manpower and material resources is increased.
Patent document CN201720362782.2 discloses a stepless electronic ultraviolet curing machine for super-smooth hydrophilic coating of medical catheter, which is cured by rotating the catheter, but the equipment is complex and the cost is high.
Patent document with application number of CN202110639494.8 discloses an auxiliary mechanism and a photo-curing machine for photo-curing, and by designing the auxiliary mechanism, a plurality of guide pipes can be rotated simultaneously, and photo-curing efficiency is improved.
