Sealing equipment for vacuum display device

Abstract

The invention discloses sealing equipment for a vacuum display device. The sealing equipment structurally comprises a sealing equipment main body, a motor box and a material taking window, wherein the motor box is installed on the bottom side of the right end of the sealing equipment main body, the material taking window is formed in the rear side of the right end of the sealing equipment main body, a sliding rod slides downwards to extrude a lower pressing plate, an electric heating wire is used for heating to enable the lower pressing plate to conduct hot-press sealing on the display device, a pressing wheel downwards slides to press the sealing position before hot-press sealing so that the flatness of the sealing position is better, cooling oil flows into the cooling pipe through a circulating cooling box, the cooling oil is circulated through an oil return pipe, the hot-press sealing position can be rapidly cooled conveniently such that the sealing effect is improved, a cooling roller is pressed downwards, through circular flowing of cooling oil in an oil storage bin, the cooling roller is ensured to be in a stable temperature state, the cooling effect is improved, a push rod is pressed downwards to drive a rotating rod to rotate, a connection rod slides rightwards on the bottom side of the push rod, a flattening roller is evenly and stably pressed downwards, and the flattening quality of the hot-pressing sealing position is improved.

Description

technical field [0001] The invention relates to the field of flat panel display devices, and more specifically, relates to a sealing device for vacuum display devices. Background technique [0002] Vacuum fluorescent display devices are widely accepted for their advantages such as self-illumination, high brightness, small size, pleasing colors, and low power consumption. Triode screens are currently the most widely used and most diverse types. The displayed content generally includes graphics and dots. Characters composed of arrays or strokes, in the process of product manufacturing, the vacuum display device needs to be sealed, but the sealing equipment will generate a lot of heat if the sealing device is sealed by heat, and the sealing of the display device cannot be cooled and strengthened in time, which will lead to The sealing of the display device is not tight, and the heat-pressed sealing part is difficult to be in a relatively flat state, thereby reducing the sealing...

[0002] Vacuum fluorescent display devices are widely accepted for their advantages such as self-illumination, high brightness, small size, pleasing colors, and low power consumption. Triode screens are currently the most widely used and most diverse types. The displayed content generally includes graphics and dots. Characters composed of arrays or strokes, in the process of product manufacturing, the vacuum display device needs to be sealed, but the sealing equipment will generate a lot of heat if the sealing device is sealed by heat, and the sealing of the display device cannot be cooled and strengthened in time, which will lead to The sealing of the display device is not tight, and the heat-pressed sealing part is difficult to be in a relatively flat state, thereby reducing the sealing quality of the display device, making the inside of the display unable to meet the required vacuum degree for use, and not cooling down the sealing equipment in time, It will make the cooling roller unable to be in a relatively stable working state, reduce the rapid and efficient cooling and reinforcement effect of the cooling roller on the heat-pressed seal, and long-term overheating will also reduce the service life of the sealing equipment
