Multi-band LED UV curing apparatus

Abstract

The invention discloses a multi-band LED UV curing apparatus. The multi-band LED UV curing apparatus includes a three-dimensional copper substrate, a plurality of LED light emitting modules uniformly distributed on the surface of the substrate, a control module for controlling the light emission of the LED light emitting modules, a graphite connecting piece fixed to one side of the substrate, and a heat dissipation unit connected with the substrate through the graphite connecting piece; each LED light emitting module comprises at least two kinds of LED light emitting chips, and the wavelengths of light emitted by different kinds of LED light emitting chips are different; the control module includes a control circuit for controlling the light emission intensity and light emission time of the LED light emitting chips; the heat dissipating unit includes a heat dissipation structure, and a fan assisting the heat dissipation structure to perform heat dissipation; and the surface of the heat dissipation structure is coated with grapheme. The multi-band LED UV curing apparatus of the invention adopted, curing under a single band can be realized independently, and curing under a plurality of bands can be also realized. The multi-band LED UV curing apparatus has the advantages of multiple-purposed performance and high heat dissipation efficiency.

Description

technical field [0001] The invention relates to multi-band LED UV curing equipment. Background technique [0002] In recent years, LED UV curing equipment is emerging and developing vigorously, especially with the continuous innovation and development of LED technology, LED chips with a wavelength of 365 nanometers have appeared, and the power has continued to increase. This makes it possible to use LED chips as a new type of LED UV curing equipment as a light source. LED UV curing equipment has just started in my country. Due to the asymmetry of equipment manufacturers' information on the needs of customers in different industries and the products to be cured, the current existing equipment uses single-band LED chips as light sources. There are still There is no UV curing equipment with multi-band LED mixed light. So that the real needs of customers can not be completely met. [0003] Existing discharge-type UV mercury lamps are characterized by a wide luminous spectrum, ...

AI Technical Summary

Problems solved by technology

[0013] 1. Single-band LED UV curing equipment cannot achieve versatility for different curing products;

[0014] 2. The curing efficiency of single-band LED UV curing equipment is not high;

[0015] 3. Single-band LED UV curing equipment often makes the curing effect unsatisfactory (for example, the surface of UV glue is not dry, and the real curing effect is not achieved, etc.);

[0016] 4. The single-band LED UV curing equipment has the risk of users buying the wrong equipment, so that the purchased equipment cannot match the product to be cured;

[0017] 5. The luminous efficiency of the LED chip is directly related to the life and temperature. As the LED emits light, the temperature around the chip increases, and the luminous efficiency of the chip decreases, resulting in a decrease in the light intensity. Within a working cycle, the light intensity is not constant
