Technical Field

The invention relates to the technical field of LCD preparation, in particular to an LCD pin curing device.

Background

The pin curing mode of common LCD products is mercury lamp UV light curing, and because the UV light wavelength of the mercury lamp is relatively dispersed, a plurality of high-power mercury lamps with power within the range of 3000W-6000W are required to work simultaneously to obtain the light accumulation with a certain wavelength. When the mercury lamp emits light, a large amount of heat is generated at the same time, so that the temperature of the UV adhesive is relatively high during curing, and the curing rate of the UV adhesive is low during photochemical reaction such as high ambient temperature, so that the product quality is affected, and longer equipment is required for installing the mercury lamp, so that the field is increased, and the energy consumption is increased.

Disclosure of Invention

The invention aims to solve the problems that a large field is needed for carrying out pin curing by adopting UV light of a mercury lamp, and the product quality is difficult to ensure, and provides an LCD pin curing device.

In order to solve the problems, the invention is realized by the following technical scheme:

An LCD pin curing device comprises a conveyor belt and a UV light source; placing the LCD to be cured on a conveyor belt; the UV light source is positioned right above the conveyor belt, and the light emitting direction of the UV light source faces downwards to the conveyor belt; the UV light source consists of a plurality of LED UV light sources and a plurality of mercury lamp UV light sources; the LED UV light source was located opposite the mercury lamp UV light source in the direction of travel of the conveyor belt.

In the scheme, the LED UV light sources and the mercury lamp UV light sources are arranged in a clustering mode, namely all the LED UV light sources are uniformly arranged at the front part of the transmission direction of the conveyor belt, and all the mercury lamp UV light sources are uniformly arranged at the rear part of the transmission direction of the conveyor belt.

In the above scheme, LED UV light source and mercury lamp UV light source adopt the interval mode of setting up, and LED UV light source and mercury lamp UV light source alternate each other promptly, and to every group alternating LED UV light source and mercury lamp UV light source, in the direction of transmission of conveyer belt, LED UV light source is located mercury lamp UV light source's relative place ahead.

In the scheme, the power of the mercury lamp UV light source (3-2) is between 500W and 1000W.

Compared with the prior art, the UV glue is deeply cured by using the LED UV light source, and then the surface of the UV glue is cured by using the mercury lamp UV light source, so that the characteristics of strong light intensity, concentrated UV light wavelength, long service life, low energy and suitability for deep curing of the UV glue are utilized, and the characteristic of suitability for surface curing of the UV glue by using the mercury lamp UV light source is utilized, and the existing LCD pin UV glue material and process can be continued; the simple transformation of equipment utilizes LED UV light source to replace partial mercury lamp UV light source among the current LCD pin solidification equipment promptly to reduce mercury lamp UV light source's power, equipment temperature and energy consumption when reducing the UV glue solidification reduce equipment and place, can improve the requirement for quality of product simultaneously.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings in conjunction with specific examples. It should be noted that directional terms such as "upper", "lower", "middle", "left", "right", "front", "rear", and the like, referred to in the examples, refer only to the direction of the drawings. Accordingly, the directions used are for illustration only and are not intended to limit the scope of the present invention.

referring to fig. 1, an LCD pin curing apparatus is mainly composed of a conveyor belt 1 and a UV light source. The LCD to be cured 2 is placed on the conveyor belt 1 and moved from front to back carrying the LCD to be cured 2. The UV light source is located directly above the conveyor belt 1 with its light emitting direction facing downward toward the conveyor belt 1 and irradiates the LCD2 to be cured on the conveyor belt 1.

In order to reduce the amount of light sources used and the energy consumption, the UV light source is composed of a plurality of LED UV light sources 3-1 and a plurality of mercury lamp UV light sources 3-2. Because the LED UV light source 3-1 has strong light intensity, concentrated wavelength of UV light, long service life and low energy, the LED UV light source is more suitable for curing the inner part of UV glue on a pin of the LCD2 to be cured, but the surface curing of the UV glue is relatively slow, and the surface curing of the mercury lamp UV light source 3-2 on a pin of the LCD2 to be cured is faster and better, so that the LED UV light source 3-1 is positioned in front of the mercury lamp UV light source 3-2 in the transmission direction of the conveyor belt 1, and the specific implementation modes thereof are two types:

The first method is as follows: the LED UV light sources 3-1 and the mercury lamp UV light sources 3-2 adopt a clustering arrangement mode, namely all the LED UV light sources 3-1 are uniformly arranged at the front part of the transmission direction of the conveyor belt 1, and all the mercury lamp UV light sources 3-2 are uniformly arranged at the rear part of the transmission direction of the conveyor belt 1. This way, the pin UV glue of the LCD2 to be cured can be internally cured first, and the pin UV glue of the LCD2 to be cured can be surface cured.

The second method comprises the following steps: the LED UV light source 3-1 and the mercury lamp UV light source 3-2 are arranged at intervals, namely the LED UV light source 3-1 and the mercury lamp UV light source 3-2 are alternately arranged, and for each group of the LED UV light source 3-1 and the mercury lamp UV light source 3-2 which alternate, the LED UV light source 3-1 is positioned in front of the mercury lamp UV light source 3-2 in the transmission direction of the conveyor belt 1. Specifically, the method comprises the following steps: the LED UV light source 3-1 and the mercury lamp UV light source 3-2 can adopt a one-to-one interval mode, namely one LED UV light source 3-1 is separated by one mercury lamp UV light source 3-2; a one-to-many interval mode can also be adopted, namely one LED UV light source 3-1 is provided with a plurality of mercury lamp UV light sources 3-2 at intervals; a many-to-one spacing mode can also be adopted, namely a plurality of LED UV light sources 3-1 are spaced by one mercury lamp UV light source 3-2; a many-to-many spacing approach may also be employed, i.e., multiple LED UV light sources 3-1 spaced by multiple mercury lamp UV light sources 3-2. This way the curing can be cycled inside and outside the pin UV glue of the LCD2 to be cured.

In addition, the LED UV light source 3-1 completes the internal curing of the UV glue, and high-intensity irradiation of the high-power mercury lamp UV light source 3-2 is not needed to penetrate through the inside of the UV glue, so that the surface of the UV glue can be cured only by selecting the mercury lamp UV light source 3-2 with smaller power, and the temperature and the energy consumption of the whole device during the curing of the UV glue can be reduced. In the invention, the mercury lamp UV light source 3-2 is a low-power mercury lamp UV light source 3-2 with power between 500W and 1000W.

The working process of the invention is as follows: coating UV glue on pins of the LCD2 to be cured, and placing the pins on the conveyor belt 1 one by one; under the driving of the conveyor belt 1, the LCD2 to be cured sequentially passes through the LED UV light source 3-1 and the mercury lamp UV light source 3-2, under the combined action of the LED UV light source 3-1 and the mercury lamp UV light source 3-2, namely, the pin UV glue of the LCD2 to be cured is internally cured through the LED UV lamp, and the pin UV glue of the LCD2 to be cured is subjected to surface curing through the mercury lamp UV light source 3-2, so that the surface curing of the UV glue of the pin of the LCD2 to be cured is realized.

Other embodiments, which can be made by those skilled in the art in light of the teachings of the present invention, are considered to be within the scope of the present invention without departing from its principles.
