Description

Technical Field

[0001] The present invention belongs to the technical field of substrate glass manufacturing, and particularly relates to an equipment and method for controlling crystallization during the forming of a glass substrate for an exposure machine. Background Art

[0002] The accuracy of an exposure machine during manufacturing directly affects the resolution and quality of a display screen. Therefore, the performance of the exposure machine, the stability of the light source, and the quality of the glass substrate are all key factors in manufacturing high-quality display screens.

[0003] Glass raw materials are melted in a melting furnace, and then the molten glass overflows and falls to form. If cold air enters the melting furnace through the bottom opening, it may indeed affect the properties of the molten glass and may cause abnormal crystallization; Temperature fluctuation: The entry of cold air will cause changes in the temperature distribution inside the melting furnace, thereby affecting the temperature uniformity of the molten glass. The sudden change in temperature may cause the formation or growth of crystal nuclei in the molten glass, affecting the uniformity and quality of the glass; Thermal stress: Cold air may cause an increase in the temperature difference between the molten glass and the inside of the melting furnace, thereby generating thermal stress. These thermal stresses may cause the generation of bubbles, cracks, or other defects in the molten glass; Chemical reaction: If the cold air contains moisture or other gases, these gases may react with the components in the molten glass, affecting the chemical composition and properties of the glass; Crystallization: The crystallization behavior in the molten glass is affected by various factors such as temperature, chemical composition, and supercooling degree. The entry of cold air may cause the molten glass to be supercooled, thereby promoting the crystallization process and making the crystals grow faster or form in a different way.

[0004] Based on this, the present invention designs an equipment and method for controlling crystallization during the forming of a glass substrate for an exposure machine to solve the above problems. Summary of the Invention

[0024] A method for controlling crystallization in the forming of a glass substrate of an exposure machine. The control method includes the following steps:

[0025] After melting raw materials into molten glass liquid in a melting furnace, the glass liquid flows into the overflow frame. When the liquid level position of the glass liquid is higher than the overflow port, the glass liquid flows out of the overflow frame through the overflow port and falls into the confluence frame. The glass liquid flows down along the inclined wall in the confluence frame. At this time, the inclined surface in the confluence frame will be covered with glass liquid, making the confluence frame have a considerable weight. The weight of the confluence frame will control the downward movement of the sliding plate and the guide sleeve. At the same time, the elastic component is squeezed and contracted. The confluence frame controls the downward movement of the squeezing column. At this time, the sliding plate controls the separation of the extending extrusion block from the control switch. When the squeezing column moves downward, by squeezing the inclined section in the squeezing hole, it controls the movement of the sliding rod in the sliding hole, realizing the control of the mutual separation movement of the left baffle and the right baffle. The left baffle and the right baffle move towards the corresponding placement grooves until the squeezing column moves to the straight section of the squeezing hole. The left baffle and the right baffle remain stationary. At the same time, the connection hole presents an open state;

[0026] After the control switch loses the press, it controls the operation of the fan assembly. When the fan assembly operates, it sucks the gas in the protective cylinder through the intermediate pipe. The gas in the protective cylinder is guided by the spiral channel formed by the spiral guide plate. At the same time, the gas flowing through the spiral channel is heated by the heat dissipated from the assembled furnace body. The heated gas passes through the intermediate pipe, the fan assembly, and the connecting pipe. The high-temperature gas in the connecting pipe enters the assembled furnace body through the upper air hole. The amount of gas in the assembled furnace body increases, and it will present a situation where the high-temperature gas is squeezed and discharged downward through the connecting hole. At the same time, the high-temperature gas in the connecting pipe is discharged downward through the lower air hole. The molten glass in the converging frame flows downward in a thin sheet through the forming material hole. The gas will blow downward along both sides of the glass formed by the overflow and downward pull of the molten glass, preventing cold air from entering the assembled furnace body through the connecting hole and contacting the just-flowed molten glass. After the molten glass flows out of the assembled furnace body downward, the pulling speed is controlled by a pulling machine.

[0027] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0028] 1. In the present invention, a protective cylinder, a spiral guide plate, a fan assembly, a control switch, a left baffle, a right baffle, a connecting pipe, an upper air hole, and a lower air hole are adopted. When the fan assembly works, it sucks the gas in the protective cylinder through the intermediate pipe. The space between the protective cylinder and the assembled furnace body is separated by the spiral guide plate to form a spiral channel. The gas enters the spiral channel from the outside and is heated by the heat dissipated from the assembled furnace body to the outside. Moreover, the path that the gas flows through is relatively long, and the gas is fully heated before reaching the fan assembly. The gas passes through the connecting pipe and exits through the upper air hole and the lower air hole respectively. The upper air hole introduces the heated gas into the assembled furnace body and will not cause the temperature in the assembled furnace body to drop rapidly. The increase in the internal gas of the assembled furnace body will cause the gas to overflow downward through the connecting hole. The gas blown downward cooperates with the gas flowing out of the furnace body to prevent external cold air from entering the assembled furnace body. It can reuse the heat dissipated by the assembled furnace body itself and actively heat the air flowing through the protective cylinder, so that the process of overflowing and downward pulling forming of the glass substrate in the assembled furnace body will not have abnormal crystallization, nor will it cause an obvious temperature difference in the assembled furnace body after the molten glass overflows.

[0029] 2. In the present invention, an overflow frame, a confluence frame, an overflow port, an elastic component, an extrusion column, an extrusion hole, a sliding rod, a left baffle, and a right baffle are adopted. When the molten glass in the overflow frame falls into the confluence frame through the overflow port, the molten glass will flow through the inclined surface in the confluence frame and cover it. At this time, the confluence frame has a considerable weight, which controls the sliding plate and the guide sleeve to slide downward along the guide rod, and simultaneously squeezes the elastic component. The extrusion column will slide along the inclined section of the extrusion hole during the downward movement of the confluence frame. By using the inclined setting, the sliding rod and the left baffle are controlled to move. The left baffle and the right baffle move toward the inside of the placement groove respectively, and the left baffle and the right baffle move away from each other, and the connection hole is opened. At this time, the molten glass in the confluence frame will flow out smoothly downward into the assembled melting furnace body. After the molten glass in the confluence frame has completely flowed out, the left baffle and the right baffle are controlled to automatically merge, avoiding random entry of sundries and dust into the assembled melting furnace body when the molten glass is not pulled and formed.

[0030] 3. In the present invention, an extension rod, a control switch, and an extension extrusion block are adopted. Before the molten glass accumulates in the confluence frame and has not flowed downward through the forming hole, the weight of the confluence frame will drive the sliding plate and the extension extrusion block to move downward. The extension extrusion block is separated from the control switch. At this time, the control switch is turned on and automatically controls the start of the fan assembly. The start of the fan and the opening of the connection hole are controlled by the weight of the molten glass in the confluence frame when the molten glass is about to flow out and form.

[0045] The adopted fan assembly 14 can suck the gas inside the protective cylinder 4 and discharge it through the connection pipe 13;

[0046] The gas inside the protective cylinder 4 is guided by the spiral channel formed by the spiral guide plate 5, and at the same time, the gas flowing through the spiral channel is heated by the heat dissipated from the assembled melting furnace body 1;

[0047] With the confluence frame 18, the molten glass flows downward along the inclined wall inside the confluence frame 18. At this time, the inclined surface inside the confluence frame 18 will be covered with molten glass, making the confluence frame 18 have a considerable weight;

[0048] With the connection pipe 13, upper air holes 27 and lower air holes 28, the high-temperature gas inside the connection pipe 13 enters the assembled melting furnace body 1 through the upper air holes 27. The amount of gas inside the assembled melting furnace body 1 increases, and the situation will occur that the high-temperature gas is squeezed and discharged downward through the connection hole 7. The gas passing through the lower air holes 28 will blow downward;

[0049] The fan assembly 14 is arranged inside the assembled melting furnace body 1. An intermediate pipe 15 is connected to the fan assembly 14.

An upper air hole 27 is provided on the upper side of the protrusion 26. A lower air hole 28 is provided on the lower side of the protrusion 26. The connecting pipe 13 penetrates through the moving and adjusting device 12 and enters the left baffle 10 and the right baffle 11. The connecting pipe 13 is communicated with the upper air hole 27 and the lower air hole 28.

[0054] The left baffle 10 and the right baffle 11 cooperate to block the connecting hole 7, preventing external sundries and dust from randomly entering the interior of the assembled furnace body 1 through the connecting hole 7.

[0055] The moving and adjusting device 12 includes a plurality of sliding rods 121. The bottom ends of different sliding rods 121 are respectively connected to the left baffle 10 or the right baffle 11. The sliding rods 121 are slidably connected in the sliding holes 9. The sliding rods 121 are rectangular. The top ends of the sliding rods 121 are connected with a moving frame 122.

[0056] The sliding rod 121 and the sliding hole 9 cooperate to guide the movement of the sliding rod 121 and the left baffle 10.

[0057] An extrusion hole 123 is provided through the front surface of the moving frame 122. The extrusion hole 123 is composed of an inclined section and a vertical section. An extrusion column 124 is slidably arranged in the extrusion hole 123. One end of the extrusion column 124 is connected to the confluence frame 18. The extrusion column 124 is cylindrical. The connecting pipe 13 penetrates through the sliding rod 121 and enters the left baffle 10 and the right baffle 11. The interiors of both the left baffle 10 and the right baffle 11 are hollow.

[0058] By using the cooperation of the extrusion column 124 and the extrusion hole 123, when the extrusion column 124 moves along the inclined section of the extrusion hole 123, it will control the sliding rod 121 to perform a horizontal movement, so as to use the up and down movement of the confluence frame 18 to control the left baffle 10 to perform a horizontal movement.

[0059] The elastic support device 21 includes a horizontal plate 211 which is connected inside the assembly furnace body. A guide rod 212 is connected to the horizontal plate 211. A limit plate 215 is connected to the top end of the guide rod 212. A guide sleeve 213 is slidably arranged outside the guide rod 212. A sliding plate 214 is connected to the outer arc surface of the guide sleeve 213. The sliding plate 214 is connected to the current collecting frame 18.

[0060] The adopted guide rod 212 guides and positions the guide sleeve 213, the sliding plate 214 and the current collecting frame 18, enabling the current collecting frame 18 to perform stable actions in the vertical direction.

[0061] An elastic component 216 is sleeved outside the guide rod 212.

The extending extrusion block 24 is connected to the sliding plate 214, and the extending rod 22 is connected to the limit plate 215.

[0062] By adopting the elastic component 216, an upward acting force is applied to the guide sleeve 213. When the glass liquid accumulates in the current collecting frame 18 and the sum of its weights is greater than the elastic force, it will squeeze the elastic component 216 and the current collecting frame 18 will move downward. When there is no glass liquid in the current collecting frame 18, the elastic force of the elastic component 216 keeps the current collecting frame 18 stable and in the upper state.

[0063] By adopting the control switch 23, after the control switch 23 loses the extrusion of the extending extrusion block 24, it will control the automatic opening of the fan assembly 14.

[0064] An exposure machine glass substrate forming and crystallization control method, the control method includes the following steps:

[0065] After the raw materials are melted into molten glass liquid in the melting furnace, the glass liquid flows into the overflow frame 16. When the liquid level position of the glass liquid is higher than the overflow port 17, the glass liquid flows out of the overflow frame 16 through the overflow port 17 and falls into the current collecting frame 18. The glass liquid flows down along the inclined wall inside the current collecting frame 18. At this time, the inclined surface inside the current collecting frame 18 will be covered with glass liquid, making the current collecting frame 18 have a considerable weight. The weight of the current collecting frame 18 will control the downward movement of the sliding plate 214 and the guide sleeve 213. At the same time, the elastic component 216 is squeezed and contracted. The current collecting frame 18 controls the extrusion column 124 to move downward. At this time, the sliding plate 214 controls the extending extrusion block 24 to separate from the control switch 23. When the extrusion column 124 moves downward, by squeezing the inclined section inside the extrusion hole 123, it controls the sliding rod 121 to move in the sliding hole 9, realizing the control of the left baffle 10 and the right baffle 11 to move away from each other. The left baffle 10 and the right baffle 11 move towards the corresponding placement grooves 8 until the extrusion column 124 moves to the straight section of the extrusion hole 123, and the left baffle 10 and the right baffle 11 remain stationary. At the same time, the connection hole 7 is in an open state.

[0066] After the control switch 23 loses the pressing, it controls the operation of the fan assembly 14. When the fan assembly 14 operates, it sucks the gas in the protective cylinder 4 through the intermediate pipe 15. The gas in the protective cylinder 4 is guided by the spiral channel formed by the spiral guide plate 5. At the same time, the gas flowing through the spiral channel is heated by the heat dissipated from the assembled furnace body 1. The heated gas passes through the intermediate pipe 15, the fan assembly 14, and the connecting pipe 13. The high-temperature gas in the connecting pipe 13 enters the assembled furnace body 1 through the upper air hole 27. The amount of gas in the assembled furnace body 1 increases, and the high-temperature gas will be squeezed and discharged downward through the connecting hole 7. At the same time, the high-temperature gas in the connecting pipe 13 is discharged downward through the lower air hole 28. The glass liquid in the confluence frame 18 flows down in a thin sheet through the forming material hole 19. The gas will blow downward along both sides of the glass formed by the overflow and downward pull of the glass liquid, preventing cold air from entering the assembled furnace body 1 through the connecting hole 7 and contacting the just-flowed glass liquid. After the glass liquid flows out of the assembled furnace body 1 downward, a pulling machine is used to control its downward pulling speed.

8. A method for controlling the crystallization of a glass substrate of an exposure machine, according to the device for controlling the crystallization of a glass substrate of an exposure machine according to claim 7, characterized in that: The control method comprises the following steps: After the raw materials are melted into molten glass in the furnace, the molten glass flows into the overflow frame (16). When the liquid level of the molten glass is higher than the overflow port (17), the molten glass flows out of the overflow frame (16) through the overflow port (17) and falls into the confluence frame (18). The molten glass flows down along the inclined wall in the confluence frame (18). At this time, the inclined surface in the confluence frame (18) is covered with molten glass, so that the confluence frame (18) has a considerable weight. The weight of the confluence frame (18) controls the sliding plate (214) and the guide sleeve (213) to move downward, and at the same time, the elastic component (216) is squeezed and contracted. The confluence frame (18) controls the extrusion column (124) to move downward. ) moves downward, at which time the sliding plate (214) controls the extended extrusion block (24) to separate from the control switch (23), and when the extrusion column (124) moves downward, it controls the sliding rod (121) to move in the sliding hole (9) by squeezing the inclined section in the extrusion hole (123), thereby controlling the left baffle plate (10) and the right baffle plate (11) to move away from each other, and the left baffle plate (10) and the right baffle plate (11) to move toward the corresponding placement groove (8), until the extrusion column (124) moves to the straight section of the extrusion hole (123), the left baffle plate (10) and the right baffle plate (11) remain stationary, and at the same time the connecting hole (7) is in an open state; When the control switch (23) is no longer pressed, the fan assembly (14) is controlled to operate. When the fan assembly (14) is in operation, the gas in the protective tube (4) is sucked through the intermediate tube (15). The gas in the protective tube (4) is guided by the spiral channel formed by the spiral guide plate (5). At the same time, the gas flowing through the spiral channel is heated by the heat dissipated from the assembled furnace body (1). The heated gas passes through the intermediate tube (15), the fan assembly (14), and the connecting tube (13). The high-temperature gas in the connecting tube (13) enters the assembled furnace body (1) through the upper air hole (27). As the amount of gas in the assembled furnace body (1) increases, the high-temperature gas will be squeezed and discharged downward through the connecting hole (7). At the same time, the high-temperature gas in the connecting pipe (13) is discharged downward through the lower gas hole (28). The molten glass in the confluence frame (18) flows downward in the form of a thin sheet through the molding material hole (19). The gas will blow downward along the two sides of the glass formed by the overflow and downward drawing of the molten glass, preventing cold air from entering the assembled furnace body (1) through the connecting hole (7) and contacting the molten glass that has just flowed down. After the molten glass flows downward out of the assembled furnace body (1), a side drawing machine is used to control its downward drawing speed.
