Light guide plate cooling equipment provided with storing device

Abstract

The invention discloses light guide plate cooling equipment provided with a storing device. The light guide plate cooling equipment comprises a conveying device, upper wind drums, lower wind drums, light guide plate cooling jigs and the cooling jig storing device. The light guide plate cooling jigs carry light guide plates and run on the conveying device; the cooling jig storing device is located at the output end of the conveying device and comprises a storing box, lifting mechanisms and lifting assemblies; the storing device is used for storing the cooling jigs from the conveying device, the lifting mechanisms and the lifting assemblies are matched to gradually lift the storing box, and the cooling jigs are stored on laminated plates of the storing box. Accordingly, workers can take away the cooling jigs in the storing box at a time, so that production efficiency is improved.

Description

Technical field: [0001] The invention relates to the light guide plate industry, in particular to a light guide plate cooling device. Background technique: [0002] With the development of the LCD TV industry, in order to show the trend of thinner thickness and lighter weight, the thickness of the light guide plate, one of the LCD TV parts, has been reduced from the original 6mm to 2-3mm. [0003] The process of screen printing light guide plate is to squeeze the ink onto the surface of the acrylic through the screen, and then dry it by infrared heating technology, and then it can be used for assembling LCD TV. In order to completely dry the ink on the light guide plate, the temperature in the infrared heating furnace in the industry is generally set at 85-90°C. Because the thickness of the light guide plate in the early stage is 6mm, after direct drying, the light guide plate will not appear due to the temperature. any functional changes. When the thickness of the light g...

Problems solved by technology

[0004] In order to improve the abnormal deformation of the light guide plate of the 2-3mm plate due to heating, the current industry is improving by reducing the baking transmission speed and lengthening the length of the infrared heating furnace in the early stage. This part of the improvement will cause a decline in manufacturing capacity, and the same also increases the cost

Now a cooling line has been added to the rear of the equipment, and fans are added to the cooling line to dissipate heat, but the wind from the fan is blown from point to surface, which will greatly lose the air volume and cannot effectively cool down. Effect
