Description

Technical Field

[0001] The utility model belongs to the technical field of UV curing, and particularly relates to a UV curing device applicable to a robot-wound gas cylinder. Background Art

[0002] Although the existing hot curing technology for wound gas cylinders has certain advantages, it also has many disadvantages. The entire hot curing process requires precise temperature control. If the temperature control is uneven, it will cause the resin at local positions of the product to be incompletely cured, or over-cured at local positions, resulting in a polymerization explosion phenomenon, leading to uneven curing of the wound gas cylinder and affecting the quality stability; the hot curing process requires high temperature to complete the curing process, which leads to high energy consumption, and a large amount of energy is used to heat the air in the internal working environment during the whole process, resulting in energy waste and further increasing the energy demand;

[0003] The entire hot curing process includes four stages: preheating, temperature rising, heat preservation, and temperature dropping. The rapid temperature rise will cause the resin to overheat and trigger a polymerization explosion phenomenon, while the rapid temperature drop will cause internal stress to be generated after the resin is cured, resulting in thermal deformation and cracking of the wound gas cylinder; the entire hot curing process takes a long time, generally at least 12 hours or more, greatly increasing the production cycle and manufacturing cost of the wound gas cylinder and affecting the production efficiency. Summary of the Invention

[0006] Preferably, the positions and angles of the front head UV lamp, the straight section UV lamp, and the rear head UV lamp can be adjusted by adjusting the distance and angle between the UV light source and the wound gas cylinder.

[0007] Preferably, the UV curing box is pulled or pushed out by a cylinder piston to drive a pull rod seat, so that the box door rotates around a rotating shaft seat to realize the opening and closing states of the box door. When the cylinder piston extends, the box door closes, and after being buffered by a buffer, the box door is limited and closed by a limit bar, which is used to realize the curing process of the wound gas cylinder. When the cylinder piston retracts, the box door opens for placing and removing the wound gas cylinder.

[0008] Preferably, the glue receiving groove is located at the bottom of the UV curing box.

[0009] Preferably, a light-shielding brush is arranged at the gap between the UV curing box and the connecting rod of the wound gas cylinder, which can effectively intercept the leakage of the UV light source inside the curing box body and avoid harm to the surrounding environment and personnel.

[0010] The utility model has the following beneficial effects: curing the wound gas cylinder by using a UV light source realizes the rapid room-temperature curing of the wound gas cylinder. At the same time, during the curing process, almost no volatile organic compounds are generated. Compared with the traditional thermal curing technology, it has the advantages of low energy consumption, safe working environment and no dangerous materials.
