Description

Technical Field

[0001] The utility model relates to the technical field of ultra-thin glass preparation, in particular to an ultra-thin glass temperature control device. Background Art

[0002] Generally speaking, mobile phones, navigation, televisions, monitors and other electronic products are suitable for glass panels. With the development of technology, display materials are also moving towards lighter and thinner. At present, some folding display screens use ultra-thin glass below 100μm, which is lighter and thinner than previous glass panels.

[0003] In the process of preparing ultra-thin glass, an ion replacement chemical strengthening process is carried out to reduce the possibility of scratches and breakage on the surface of the ultra-thin glass.

[0004] The ion replacement chemical strengthening process mainly involves preheating the original glass, then immersing the preheated original glass in molten potassium nitrate at about 400°C, replacing the sodium ions in the original glass with the potassium ions in potassium nitrate, performing ion replacement chemical strengthening treatment, then cooling the replaced strengthened glass, and then washing away the potassium nitrate remaining on the surface of the strengthened glass.

[0005] In the above process, the original glass needs to be preheated before being soaked in molten potassium nitrate to prevent the circular plate glass from being damaged due to the balance between surface compressive stress and internal tensile stress caused by thermal shock during the ionization expansion strengthening process.

[0006] In addition, the original glass is immersed in molten potassium nitrate at about 400°C for ion chemical strengthening treatment, and then goes through a cooling process before being washed with hot water at about 80°C to prevent the strengthened glass from being damaged by thermal shock during hot water washing.

[0007] In the prior art, when the ultra-thin glass is loaded inside a preheating furnace equipped with a heater, a fan is used to circulate the air heated in the heater inside the preheating furnace to preheat the ultra-thin glass. However, the disadvantage of the prior art is that the heated air cannot flow smoothly between the loaded ultra-thin glasses, causing thermal deviation between the middle part and the frame part of the loaded ultra-thin glass, thereby causing stress deviation in the ultra-thin glass and reducing product quality. It is worth mentioning that the thinner the ultra-thin glass is, the more serious the stress deviation caused by thermal deviation during preheating. Utility Model Content

[0030] The air heating injection unit 20 includes an injection plate 21, a cover plate 22 and a heating unit 24. The heating unit 24 is vertically arranged inside the first side wall 11.

[0031] An airflow guide plate 25 is vertically installed in the middle of the lower part of the cover plate 22 in the heating space 26. A gap is set between the bottom of the airflow guide plate 25 and the engineering chamber 10. The airflow guide plate 25 divides the heating space 26 into a downward flow channel 2 and an upward flow channel 3.

[0032] The longitudinal injection holes 1 arranged in the vertical direction are located between two adjacent ultra-thin glasses G, and the size of the injection holes 1 located at the lower part of the injection plate 21 is smaller than the size of the injection holes 1 located at the upper part of the injection plate 21 .

A plurality of suction holes 4 are arranged in an array on the front panel 31. The vertically arranged longitudinal suction holes 4 are located between two adjacent ultra-thin glasses G.

[0034] The air circulation unit 40 includes a circulating air duct 41, a circulating fan 42 and a filter unit 43. The circulating air duct 41 includes a main air duct portion 5 and a branch air duct portion 6. There are two groups of branch air duct portions 6, which are respectively arranged on both sides of the bottom of the engineering room 10. One end of the two groups of branch air duct portions 6 are respectively connected to the two sides of the side shell 33, and the other end of the two groups of branch air duct portions 6 are connected to the bottom of the main air duct portion 5. The main air duct portion 5 is arranged in the engineering room 10, and the top is connected to the connecting hole 23. The circulating fan 42 and the air intake filter unit 43 are sequentially arranged inside the main air duct portion 5 along the air flow direction.

[0035] The exhaust unit 50 is arranged outside the second side wall 12 above the suction member 30, and the exhaust unit 50 includes an exhaust duct 51, an exhaust fan 52 and an exhaust filter unit 53.

[0036] The heating unit 24 includes a plurality of rod heaters, which are disposed between the first side wall 11 and the airflow guide plate 25 , and the rod heaters can achieve temperature control.

[0037] The working principle of the utility model is as follows: first, ultra-thin glasses G are loaded in the loading space A of the engineering chamber 10. These ultra-thin glasses G are loaded on the loading tool and are located in the loading space A. At this time, adjacent ultra-thin glasses G are spaced a certain distance apart in the horizontal direction, and each ultra-thin glass G is positioned in a direction perpendicular to the bottom surface of the loading space A, and the horizontal length direction of each ultra-thin glass G is in the direction of the first and second side walls of the engineering chamber 10, that is, both ends are facing the direction of the air heating injection unit 20 and the suction component 30.

[0038] When the loading space A of the engineering room 10 is loaded with ultra-thin glass G, the air heating spray unit 20, the exhaust unit 50, and the air circulation unit 40 can work separately, or the ultra-thin glass H can be loaded in the loading space A of the engineering room 10 when the air heating spray unit 20, the exhaust unit 50, and the air circulation unit 40 are working separately.

[0039] When the air heating injection unit 20, the exhaust unit 50 and the air circulation unit 40 are working respectively, the air heated to the set temperature by the air heating injection unit 20 is horizontally injected into the loading space A of the engineering room 10, and the heated air injected into the loading space A passes through the ultra-thin glass G placed in the loading space A. Part of the air passing through the ultra-thin glass G is discharged to the outside of the engineering room 10 by the exhaust unit 50, and the remaining air passing through the ultra-thin glass G is sucked into the component 30. The air sucked into the component 30 circulates through the air circulation unit 40 and flows into the air heating injection unit 20. The air flowing into the air heating injection unit 20 is heated to the set temperature from the air heating injection unit 20 and is injected into the loading space A for repeated operation.

[0040] When the ultra-thin glass G entering the engineering chamber 10 needs to be preheated at about 400°C for ion replacement chemical strengthening, the temperature of the heating unit 24 is increased to the set preheating temperature, and then the ultra-thin glass G is heated. After the ultra-thin glass G put into the engineering chamber 10 completes the ion replacement chemical strengthening, the ultra-thin glass needs to be placed in hot water for cleaning. At this time, the temperature of the heating unit 24 needs to be lowered to the set cleaning temperature of about 80°C, and the ultra-thin glass G is cooled at the same time.

[0041] The utility model sprays the air heated in the air heating spray unit in a horizontal direction, so that the airflow flows between the ultra-thin glasses located in the bearing space, thereby heating or cooling the ultra-thin glasses. The airflow flows more smoothly, so that the middle part and the edge part of the ultra-thin glasses are evenly heated or cooled, thereby minimizing the thermal deviation of the ultra-thin glasses. The air suction port located on the opposite side absorbs the airflow sprayed by the heating spray unit, and sends it into the air heating spray unit again through the circulation system, so that the air is heated again and sprayed out again after heating, thereby forming an internal circulation with air heating, which greatly improves the quality of thermal strengthening of the ultra-thin glasses.

[0042] When the utility model cools the ultra-thin glass, the air heated in the air heating injection unit is injected horizontally to flow between the ultra-thin glasses located in the bearing space, so that after the ultra-thin glass is cooled, relatively high-temperature air is discharged through the exhaust unit, and relatively low-temperature air is sucked in through the air suction unit, and then the ultra-thin glass is cooled by the injection-circulation system. The above glass cooling operation mode is external circulation, which can effectively prevent the collision of high-temperature airflow and low-temperature airflow, prevent the loss of ultra-thin glass caused by eddy current, improve energy efficiency, and shorten production time.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
