Description

Technical Field

[0001] This invention relates to the field of glass manufacturing technology, specifically to a method for manufacturing 3D display glass and the 3D display glass thereof. Background Technology

[0002] 3D curved glass is a three-dimensional glass that forms a continuous curved surface in the X / Y / Z axis directions. It has the characteristics of being thin, light and resistant to fingerprints. The product uses a hot bending forming process to soften and shape flat glass. It is mainly used in the fields of waterfall screens for smartphones, tablet computers, smartwatch faces, car center console screens and architectural decoration.

[0003] The patent application with application number CN202110454522.9 mentions a "display device and 3D curved glass processing method". This patent uses hot bending to bend the curved part to a first bending angle, and then uses the glass cooling and springback to fix the bending angle of the curved part to the bending angle to obtain 3D curved glass. Hot bending process has low equipment requirements, the structure of the glass plate is simple during the cooling process, no hot pressing mold is required, the cost is low, and the adjustment is flexible.

[0004] In the prior art, a stable float glass bending device according to Chinese patent application number 202121629354.4 also uses a servo motor to drive the active threaded rod and the driven threaded rod to rotate in conjunction with a belt, thereby driving the connecting end plate to move downward at a uniform speed. This allows the bending assembly to achieve stable bending of the glass. The limiting wall groove and pulley can limit the up and down movement of the connecting end plate to improve its stability.

[0005] However, existing technologies for processing 3D curved glass rely solely on direct hot bending, requiring secondary shaping using the self-rebound ability of the cooled 3D curved glass. This results in ineffective control over the shape of the 3D curved glass during processing. Furthermore, directly using pneumatic hot bending and gravity-based hot bending makes it impossible to precisely control the bending position of the glass. Consequently, actual production requires a lengthy shaping process, compromising product quality and impacting yield and production efficiency. Summary of the Invention

[0006] This invention provides a method for manufacturing 3D display glass and its curved display glass, which can effectively solve the problem mentioned in the background art that the existing technology for processing 3D curved glass only uses direct hot bending and requires secondary shaping by utilizing the self-springback ability of the cooled 3D curved glass, resulting in the inability to effectively control the shape of the 3D curved glass during processing.

[0009] S2. Thermogravimetric gas setting: The pre-treated glass substrate is placed on the top of the shaping mold in the multi-temperature control frame. The glass substrate is heated by an electric heating processor. The glass substrate is then subjected to bending treatment by its own weight and micro-airflow through the alignment spray tube to achieve the initial shaping treatment of the glass substrate.

[0010] S3. Hot pressing and shaping: The pre-shaped and softened glass substrate is pressed and shaped by the shaping bottom mold and the shaping top mold. The softened glass substrate is then precisely aligned and pressed and shaped again with the positioning universal joint and the forming pressure plate to achieve the forming process of the glass substrate.

[0011] S4. Post-cooling treatment: The display glass is cooled through the gas injection pipe, the inlet and outlet straight blowing pipe and the return spray bend pipe to practice the curing and shaping treatment of the display glass.

[0060] A 3D display glass, comprising curved display glass;

[0061] The curved display glass is a four-curved edge glass.

[0062] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0063] 1. Equipped with a pressure-distributing flow control component, the entire control multi-section temperature control frame is separated by an insulated upper spray separation frame. With the top and bottom temperature control, an internal air pressure difference is formed. Combined with the lower punch fixing sleeve and the alignment lower spray treatment pipe, a slow airflow is formed to perform multi-position pneumatic bending and synchronous self-weight bending dual treatment on the softened glass base material. With the mold support, the initial control shaping is achieved. The shaping bottom mold and shaping top mold are pressed together by the equalizing hydraulic cylinder, the processing hydraulic cylinder and the processing pressing plate to achieve the glass base material shaping treatment. The shaping hydraulic cylinder, the separating hydraulic cylinder, the positioning universal joint and the forming pressure plate are used to perform secondary center pressing shaping and tertiary edge pressing shaping on the shaping top mold to achieve the hot pressing shaping treatment of the softened flat glass base material edge. The three-stage separation extrusion shaping is used to ensure the shape accuracy of the glass forming and improve product quality.

[0064] Protective gas is injected into multiple locations inside the mold through the injection operation pipe, inlet and outlet straight-blowing inclined pipe, return spray bend pipe, and protective gas tank. The airflow speed is controlled by the guide fan and inlet and outlet straight-blowing inclined pipe. The mold and finished product are slowly cooled by the low-temperature airflow. The internal airflow is also interconnected to achieve slow cooling while recycling the high-temperature protective gas, ensuring continuous and stable heating and cooling during production. The temperature inside the multi-chamber temperature control frame is controlled to different degrees by the electric heating processor and isolation limiting plate, realizing different levels of heating and cooling treatment in the internal multi-chamber. The feeding speed of the heat-resistant protective conveyor belt is controlled by the linkage gear and multi-tooth conveyor belt. Through continuous switching and multi-chamber level heating and cooling treatment, the entire process of preheating, softening, shaping and cooling of the mold and glass substrate is processed simultaneously, reducing the occurrence of thermal stress damage to the material caused by rapid heating and cooling.

[0065] By combining hot bending and hot pressing, and utilizing coordinated heating and cooling, along with uniform processing throughout the softening and curing process, this technology effectively solves the problem in existing technologies where the shape of curved glass cannot be precisely controlled solely through hot bending and subsequent springback after cooling. By employing pneumatic hot bending, gravity-fed hot bending, shaping hot pressing, and edge-correcting hot pressing, along with slow heating and cooling, and mold control, the shape of the curved glass can be effectively controlled. Simultaneous pretreatment and forming processes reduce waiting time during production, ensuring both product quality and production efficiency. Furthermore, the controllable production process improves the actual yield rate, guaranteeing the quality of automotive curved display glass.

[0066] 2. Equipped with a dual-movement slag removal component, the material feeding electric push rod, material feeding fixed clamp, electric pick-and-place device, elastic pressing plate and suction plate are used to handle the loading and unloading of the shaping bottom mold and glass substrate. The feeding motor drives the double support fixed clamp to change position, realizing the simultaneous operation of material loading and unloading. The simultaneous placement of the mold and glass substrate increases the feeding speed. The material picking electric push rod drives the material picking fixed clamp to move. The pressing cylinder, suction plate, external electric push rod and electric pick-and-place device are used to handle the material loading and unloading of the mold and glass. The waste collection fixed box is used for waste collection. The pick-and-place cylinder drives the pick-and-place fixed transfer frame to move. The lifting cylinder drives the electric pick-and-place device to clamp the shaping top mold. The conveying preheating box heats the shaping top mold, realizing the mold loading and preheating process.

[0067] The system utilizes electric sliding rails to move the sliding frame, inserting the top mold into the clamping frame for feeding. By coordinating feeding preheating with moving feeding and clamping feeding, and employing bidirectional feeding and unloading, alignment angle correction, rotary waste removal, and bidirectional moving mold placement in the middle, the system achieves rapid feeding and unloading operations, improving overall processing speed. This reduces the problem of equipment temperature drop and increased energy consumption caused by prolonged opening and closing, which affects actual processing efficiency.

[0068] In summary, by combining the pressure-distributing flow control component and the dual-movement slag removal component, and utilizing bidirectional rapid feeding and mold feeding preheating synchronous processing, along with multi-stage hot bending and hot pressing shaping processes, rapid and accurate alignment processing can be achieved during the forming of curved display glass, improving product quality and production efficiency. At the same time, the use of multi-stage serial circulation processing ensures stable temperature during equipment processing and reduces energy consumption. Attached Figure Description

[0134] like Figure 11 As shown, the present invention provides a technical solution, a 3D display glass, including a curved display glass 4;

[0135] Curved display glass 4 is a four-curved edge glass.

[0136] The working principle and usage process of this invention are as follows: When manufacturing curved display glass 4, the workers use an external cutting device to cut the flat glass base material of curved display glass 4 according to the required size. After cutting, the cut flat glass base material is surface treated by CNC precision engraving, surface polishing and fine grinding, and ultrasonic cleaning. After treatment, the flat glass base material is collected by the workers and transported to the loading position on the side of the multi-temperature control rack 1. At the same time, the workers place the shaping bottom mold 207 on the loading position on the side of the multi-temperature control rack 1 to realize the pre-production preparation of curved display glass 4.

[0137] After preparation, the feeding electric push rod 303 drives the feeding fixed clamp 304 to move to the feeding position. The electric pick-and-place device 318 clamps and picks up the shaping bottom mold 207. At this time, the feeding electric push rod 303 drives the feeding fixed clamp 304 to reset. The feeding motor 301 drives the double support fixed clamp 302 to rotate, realizing the switching of the two sets of feeding fixed clamps 304. After the switching is completed, the pressure cylinder 311 drives the elastic pressing sheet 312 to move down, so that the bottom of the elastic pressing sheet 312 and the adsorption plate 313 contact the top of the processed flat glass substrate. The air between the adsorption plate 313 and the flat glass substrate is extracted by the pressure pump 315 and the processing air pipe 314. The flat glass substrate is adsorbed to the bottom of the adsorption plate 313 through the negative pressure environment, realizing the fixing of the flat glass substrate. When the flat glass substrate is adsorbed and fixed, the above picking operation of the shaping bottom mold 207 is repeated to realize the switching of feeding process.

[0138] When a set of double-support fixed clamping frames 302 picks up material, the pneumatic partition cover 325 is driven by the closed-pressure pneumatic slide rail 324 to open the overall control multi-division temperature control frame 1. Another set of material feeding fixed clamping frames 304 holding the shaping bottom mold 207 is driven into the inside of the overall control multi-division temperature control frame 1 by the material feeding electric push rod 303, so that the material feeding fixed clamping frame 304 moves to the side end of the heat-resistant protective conveyor belt 205, inserts the shaping bottom mold 207 into the side end of the clamping limit sleeve 206, and realizes the fixing of the shaping bottom mold 207. After the fixing is completed, the pneumatic partition cover 325 is driven by the closed-pressure pneumatic slide rail 324 to close the overall control multi-division temperature control frame 1. The electric heating processor 224 is used to perform electric heating treatment on the inside of the overall control multi-division temperature control frame 1 to realize the alignment feeding and preheating treatment of the shaping bottom mold 207. At the same time, multiple sets of electric heating processors 224 control the temperature of each position of the overall control multi-division temperature control frame 1.

[0139] During the preheating process, the closed-isolation hydraulic cylinder 225 drives the isolation limiting plate 226 to connect the entire multi-isolation temperature control frame 1. After connection, the hydraulic motor 203 drives the linkage gear 202 and the conveyor roller 201 to rotate along the entire multi-isolation temperature control frame 1. The linkage gear 202 meshes with the multi-tooth conveyor belt 204, and the rotating linkage gear 202 drives the multi-tooth conveyor belt 204 to rotate. The rotating multi-tooth conveyor belt 204 drives the heat-resistant protective conveyor belt 205 to rotate along the entire multi-isolation temperature control frame 1, thereby driving the placement of a fixed... The positioning and limiting sleeve 206 of the bottom mold 207 is rotated and repositioned. After the first set of bottom molds 207 is rotated and repositioned, the feeding operation of the feeding bracket 304 is repeated. During the feeding process, the flat glass base material at the bottom of the feeding bracket 304 is moved down by the pressing cylinder 311, which drives the elastic pressing sheet 312 and the adsorption plate 313 to place the flat glass base material on the top of the bottom mold 207. At the same time, the second set of bottom molds 207 is clamped to the side of the positioning and limiting sleeve 206, realizing the simultaneous feeding of the flat glass base material and the bottom mold 207.

[0140] After the material is fed, the pneumatic partition cover 325 is used again to close the temperature control frame 1. The flat glass base material and the shaping bottom mold 207 are preheated simultaneously by the electric heat processor 224. After the preheating is completed, the process of conveying by the heat-resistant protective conveyor belt 205 is repeated to move the flat glass base material and the shaping bottom mold 207 to the second heating chamber. Then the feeding process is repeated to realize the continuous feeding and preheating of the flat glass base material. After the preheating is completed, the flat glass base material is continuously heated by the second heating chamber and the third heating chamber. During the movement, the flat glass base material gradually rises from room temperature to 700°C. Then the heat-resistant protective conveyor belt 205 is used to transport the flat glass base material to the fourth heating chamber. At this time, the electric heat processor 224 located at the bottom of the heat-insulating spray separation frame 220 in the fourth heating chamber heats the temperature inside the chamber to 730°C.

[0141] Meanwhile, the electric heating processor 224 located at the top of the thermal insulation spray separation frame 220 inside the fourth heating chamber heats the internal temperature of the chamber to 725°C, creating a temperature difference inside. This temperature difference creates a pressure difference, causing the hot airflow at the top to spray down along the downward fixing sleeve 222 and the alignment downward spray treatment pipe 221 to spray protective gas. The slow protective gas blows directly downwards and bends the softened flat glass substrate. At this time, the self-weight exhaust sliding block 223 opens and closes the thermal insulation spray separation frame 220 to control the air pressure inside the fourth heating chamber. Through heating and softening and slow airflow, the flat glass substrate is softened uniformly. After the fourth heating chamber has softened for a certain period of time, the flat glass substrate with the initial edge bending is moved to the fifth heating chamber for heating, gravity bending and airflow direct spray bending treatment, realizing the secondary softening and bending treatment of the flat glass substrate.

[0142] During the softening and shaping process of the flat glass substrate, the worker places the shaping mold 215 inside the conveying preheating box 208. At this time, the shaping mold 215 is preheated to 400°C by the conveying preheating box 208. Then, the isolation limiting plate 226 is driven by the closed hydraulic cylinder 225 to connect the two chambers inside the conveying preheating box 208. After the connection is completed, the pick-and-place transfer frame 322 is moved to the position of the shaping mold 215 inside the conveying preheating box 208 by the pick-and-place cylinder 321. Then, the lifting cylinder is used to... 323 drives the electric pick-and-place device 318 to move to the top of the shaping mold 215. The electric pick-and-place device 318 clamps and fixes the shaping mold 215. After clamping, the lifting cylinder 323 and the pick-and-place cylinder 321 drive the shaping mold 215 to move to one side of the inside of the conveying preheating box 208. Then, the isolation hydraulic cylinder 225 drives the isolation limiting plate 226 to separate the conveying preheating box 208. At this time, the shaping mold 215 is heated to 750°C to realize the material picking and repeated preheating treatment of the shaping mold 215.

[0143] The pressure equalizing hydraulic cylinder 209 drives the pressure limiting fixing frame 210 to rise, and the inlet and outlet electric slide rail 211 drives the inlet and outlet sliding frame 212 to enter the inside of the conveying preheating box 208 along the pressure limiting fixing frame 210. The inlet and outlet sliding frame 212 is moved to the bottom of the shaping top mold 215. At this time, the lifting cylinder 323 drives the electric pick-and-place device 318 to move down, and the shaping top mold 215 is placed inside the clamping and fixing frame 214 to realize the feeding process of the shaping top mold 215. After the feeding is completed, the pressure equalizing hydraulic cylinder 209 and the inlet and outlet electric slide rail 211 drive the shaping top mold 215 to move into the inside of the whole control multi-division temperature control frame 1 to realize the feeding process of the shaping top mold 215.

[0144] After initial softening and shaping, the flat glass substrate and the shaping bottom mold 207 are moved to the shaping top mold 215. The pressure equalizing hydraulic cylinder 209 drives the pressure limiting fixing frame 210, the sliding frame 212, and the clamping fixing frame 214 to move downward, so that the shaping top mold 215 and the shaping bottom mold 207 are fitted together. After the fitting is completed, the processing hydraulic cylinder 234 drives the processing pressing plate 235 to move downward. The processing pressing plate 235 pushes downward, so that the shaping bottom mold 207 and the shaping top mold 215 are fitted together. After the fitting is completed, the pressure equalizing hydraulic cylinder 209 pushes the pressure limiting fixing frame 210 to move downward, so that the shaping bottom mold 207 and the shaping top mold 215 perform initial hot pressing and shaping treatment on the softened flat glass substrate.

[0145] After the initial hot pressing and shaping is completed, the heat-resistant protective conveyor belt 205 drives the shaping bottom mold 207 and shaping top mold 215 to move and reposition to the position of the forming pressure plate 219. The forming hydraulic cylinder 216 drives the forming pressure plate 219 to move downward, and performs a second pressing process on the center position of the shaping bottom mold 207 and shaping top mold 215 to achieve a second hot pressing and shaping process. After hot pressing, it moves again to the split positioning hydraulic cylinder 217. At this time, the multi-part split positioning hydraulic cylinder 217 pushes the positioning universal joint 218 and the forming pressure plate 219 downward to press them to the top of the shaping top mold 215. The split positioning hydraulic cylinder 217 and the positioning universal joint 218 adjust the downward pressure point of the forming pressure plate 219, thereby squeezing the edge of the shaping top mold 215. By using edge pressure correction, the edge hot pressing and shaping process of the softened flat glass base material is achieved. The three-stage split extrusion shaping process ensures the steady processing of the 3D bending shaping of the flat glass base material.

[0146] After the flat glass substrate, the shaping bottom mold 207, and the shaping top mold 215 are completed, they are moved to the cooling position of the multi-chamber temperature control frame 1. At this time, the gas injection operation pipe 227, the inlet / outlet direct-blowing inclined pipe 229, and the return spray bend pipe 230 are opened through the processing restriction valve 231, so that the multiple chambers inside the multi-chamber temperature control frame 1 are interconnected. After the interconnection is completed, the protective gas in the protective gas tank 228 enters the material outlet position inside the multi-chamber temperature control frame 1 through the gas injection operation pipe 227. At this time, the protective gas enters the position near the heat-resistant protective conveyor belt 205, and is then drawn by the extraction guide fan 233 and the inlet / outlet direct-blowing inclined pipe 229. 9. The protective gas is extracted and flows along the inlet and outlet of the direct blowing inclined pipe 229 and the direct spray treatment bucket 232, and performs surface direct blowing cooling treatment on the shaped bottom mold 207 and the shaped top mold 215. Through multi-stage direct blowing cooling, the shaped curved display glass 4, the shaped bottom mold 207 and the shaped top mold 215 are gradually cooled, and the temperature is slowly reduced from 730℃ to 100℃. In addition, the high temperature protective gas is extracted and injected into the feeding preheating position inside the whole control multi-partition temperature control rack 1 in conjunction with the return spray bend pipe 230, so as to realize the recycling of high temperature protective gas and rapid preheating treatment, and ensure the continuity and stability of its temperature rise.

[0147] After cooling, the curved display glass 4, the shaping bottom mold 207, and the shaping top mold 215 are moved to the discharge position. The pneumatic sliding rail 324 drives the pneumatic partition cover 325 to open the multi-partition temperature control frame 1. The material-picking electric push rod 307 moves the material-picking clamp 308 to the material-picking position. The correction motor 309 drives the correction clamp 310 to rotate, adjusting the position of the correction clamp 310 according to the positions of the curved display glass 4, the shaping bottom mold 207, and the shaping top mold 215. The pressure cylinder 311 drives the elastic pressure plate 312 and the adsorption plate 313 to adsorb the shaping top mold 215. After adsorption, the material-picking electric push rod 307 resets the material-picking clamp 308, and the material-picking motor 305 drives the multi-partition clamp 308 to rotate. 6. Rotate and switch the material picking fixture 308. After switching, the material picking fixture 308 is moved to the material picking position by the material picking electric push rod 307. After the material picking is completed, the qualified curved display glass 4 is picked up by the elastic pressing sheet 312 and the adsorption plate 313. After the picking is completed, the waste collection fixing box 320 is moved to the discharge position by the interlocking pneumatic slide rail 319. Then, the heat-resistant protective conveyor belt 205 rotates and the unqualified curved display glass 4 is rotated and dropped into the inside of the waste collection fixing box 320 to achieve waste collection. The shaping bottom mold 207 is rotated to the demolding position. The electric picker and placer 318 is driven by the external electric push rod 317 to clamp the shaping bottom mold 207 and remove the shaping bottom mold 207 from the clamping limit sleeve 206 to achieve the unloading process.
