Description

Film exposure table for glass production

Technical field

The invention relates to an exposure table, in particular to a film exposure table for glass production.

Background technique

Exposure is to cover the mask on the photoresist-coated glass surface and irradiate it with an exposure lamp; the photoresist in the light-receiving part undergoes a chemical reaction to change the solubility of this part of the photoresist in the developing solution. Therefore, after development, the photoresist film Shows a pattern consistent with the mask. In the prior art, film is mainly used as the mask. The main problems are as follows: First, the light is uneven, so that the degree of light received on the coated glass is not uniform. The degree of chemical reaction of the photoresist in the light-receiving part is also inconsistent. Second, when the exposure lamp is operating, there is a situation in which electrical energy is converted into thermal energy, which causes the temperature of the exposure chamber and the exposure table to rise. A cooling device is required to perform the exposure chamber and the exposure table. Cooling, the existing cooling device is fixed, unable to uniformly cool each area of the exposure chamber and the exposure table, resulting in uneven heating of the original on the exposure table, distortion of the image on the film, and the quality of the exposure process cannot be guaranteed; Therefore, in order to solve the above problems, it is necessary to develop a film exposure table for glass production.

The purpose of the present invention is achieved as follows: a film exposure table for glass production, including a frame, a conical light box, an exposure lamp, an exposure platform, a cover plate, a vacuum pump, a vacuum air pipe, a cooler, a cooling pipe and an air outlet device, Wherein, the frame is provided with a conical light box, the exposure light is provided in the conical light box, the frame is provided with an exposure platform above the conical light box, and the exposure platform is provided with a cover plate, One side of the cover plate and one side of the exposure platform are hinged together, the exposure platform and the cover plate surround a cavity containing the exposed object, the cover plate is covered with a sealing cloth, and the inside of the cover plate A sealing strip is provided at the edge, and a vacuum pump is provided on the frame. The vacuum pump is connected to a sealed cavity formed by the cover plate and the exposure voucher through a vacuum air pipe. A cooling machine is also provided on the frame. The cooler is connected to an air outlet device through a cooling pipe. The air outlet device is provided on the upper sides of the two sides of the inside of the conical light box, a connection plate is provided in the conical light box, and a connection shaft is provided at both ends of the air outlet device. The connecting shaft is rotatably connected to the connecting plate, and a rotating electric machine is also provided on the connecting shaft.

There are three exposure lamps.

The conical light box is also provided with a conventional lighting lamp.

An exhaust fan is arranged on the conical light box.

After the cover plate is covered with a sealing cloth, the cavity formed by the cover plate is in contact with the exposure platform through the sealing strip, and the cavity formed by the cover plate is airtight.

The beneficial effects of the present invention are: through the setting of the conical light box in the present invention, the light of the exposure lamp is better reflected, the light is more uniform, the waste of light energy is reduced, and the exposure efficiency is improved; through the cooling device and the air outlet device The setting can better cool the exposure chamber and the exposure table. At the same time, the rotating device of the air outlet device can adjust the temperature of each area of the exposure chamber and the exposure table evenly, making the exposure efficiency higher. Overall, the The invention has the advantages of uniform illumination, uniform and comprehensive cooling, small energy loss, and high exposure efficiency.
