Description

Technical Field

[0001] The utility model relates to the technical field of UVA curing, in particular to a UVA industrial curing module. Background Art

[0002] UV curing means that under the irradiation of ultraviolet light, the photoinitiator absorbs photons of a specific wavelength, is excited to an excited state, forms free radicals or cations, and then through the transfer of intermolecular energy, the polymerizable prepolymer and photosensitive monomer become excited states, generating charge transfer complexes, which are continuously cross-linked and polymerized, and produce high molecular polymers that are cured into a three-dimensional network structure in a very short time. Among them, absorbing radiation energy and initiating the cross-linking and curing of unsaturated double bonds of monomers and oligomers is a key part of the UV curing system. UV (UVled) curing has the advantages of short time, good performance, high efficiency, no pollution and harmlessness to the human body.

[0003] At present, urban pipeline repair is mainly done by excavation, which is time-consuming, labor-intensive, costly, and easily causes traffic jams. For this reason, we propose a UVA industrial curing module. Utility Model Content

[0004] The purpose of the utility model is to provide a UVA industrial curing module, which has the advantages of non-excavation pipeline repair and time-saving, labor-saving and low cost, and solves the problem that current urban pipeline repair is mainly excavation-type repair, which is time-consuming, labor-intensive, costly, and easily causes road traffic congestion.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a UVA industrial curing module, comprising a circuit layer, a thermally conductive and heat-dissipating copper substrate, a dam layer, a circuit layer, a UVled chip and an optical lens, wherein the circuit layer on the thermally conductive and heat-dissipating copper substrate has six evenly distributed light-emitting areas, and four symmetrically distributed UVled chips are arranged in the light-emitting areas. A dam layer is arranged on the top of the circuit layer, and the dam layer includes three evenly distributed dam components. Optical lenses are arranged in the upper and lower corresponding areas of the dam component and the light-emitting areas. A circuit layer is arranged at the right end of the circuit layer, and external wiring pads are symmetrically arranged on the surface of the circuit layer.

[0006] Preferably, the circuit layer, the heat-conducting and heat-dissipating copper substrate and the front and rear ends of the dam component are provided with mounting holes, and the diameter of the mounting holes is between 2 mm and 8 mm.

[0007] Preferably, the wattage of a single UVled chip is three watts, and the UVled chip is installed in the light-emitting area by means of silver glue.

[0008] Preferably, the UVled chips in the light-emitting area are six 2*2 series arrays, and the electrodes and wire pins of the chips are connected by gold wires to form a 2-in-parallel and 12-in-series series-parallel circuit.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] 1. The utility model fixes 24 UVled chips on the circuit layer by Die-bonding with silver glue, and then uses gold wire to connect the electrodes and wire pins of the UVled chip by Wire-Bonding to form 6 2*2 LEDs in series, and an optical lens is installed above the UVled chip to change the focal length. The heat generated by the light-emitting UVled chip is conducted to the radiator through the thermally conductive and heat-dissipating copper substrate below, and the UV light emitted by the UVled chip can be used to cure the photosensitive material. Since the curing time of light curing is short, a one-meter pipeline can be repaired in a few minutes, which can greatly reduce the engineering time and cost compared to several hours of excavation repair.
