[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

Embodiment 1

[0022] as attached figure 1 To attach Figure 5 Shown:

[0023] A sealing device for a vacuum display device according to the present invention, its structure includes an observation window 1, a sealing device main body 2, a tool box 3, feet 4, an operation panel 5, a motor box 6, and a material retrieving window 7, and the observation window 1 is set On the left side of the front end of the sealing device main body 2, the tool box 3 is embedded and installed on the bottom of the sealing device main body 2, the foot 4 is welded on the bottom of the tool box 3, and the operation panel 5 is arranged on the sealing device main body 2 On the right side of the front end, the motor box 6 is installed on the right bottom side of the sealing equipment main body 2, and the right end rear side of the sealing equipment main body 2 is provided with a material taking window 7, and the sealing equipment main body 2 includes a box body 21, a vacuum Air pump 22, conveyer belt 23, cooling de...

Embodiment 2

[0030] as attached Figure 6 to attach Figure 7 Shown:

[0031] Wherein, the cooling structure 26 includes an oil storage bin 261, a cooling roller 262, a connecting shaft 263, a tap inlet pipe 264, and a tap outlet pipe 265, and the oil storage bin 261 is embedded and installed inside the cooling roller 262. The left end of the connecting shaft 263 is embedded and connected with the right end of the cooling roller 262, and the upper and lower sides of the opening of the right end of the oil storage bin 261 are respectively cooled by the tap inlet pipe 264 and tap outlet pipe 265 and the bottom end of the oil storage bin 261. The device 24 is connected. The material of the cooling roller 262 is aluminum, and the heat conduction efficiency is good, so that the temperature of the heat-pressed seal of the display device is rapidly cooled. The branch inlet pipe 264 flows the cooling oil into the cooling roller 262, and cooperates with the tap outlet 265 flows out the cooling oi...
