Description

Technical Field

[0001] The invention belongs to the technical field of vacuum glass manufacturing, and in particular relates to a full-tempered vacuum glass production line without an air extraction port. Background Art

[0002] At present, the well-known "one-step, no exhaust port" vacuum glass adopts a single-tank production form of multiple large vacuum tanks in terms of production. The interior of the vacuum tank adopts a multi-layer drawer-type shelf structure. The heat required for the edge sealing welding material of the vacuum glass adopts a contact heating method. Glass fiber cloth or high-silica cloth is used as an insulating material between the heater and the glass being produced, and ceramic plates or ceramic tiles are used as insulating materials. The large vacuum tank is first evacuated to a high vacuum, and then the solder used for edge sealing between the glass and the glass is melted through contact heating to play a role in edge sealing. After the edge metal is sealed, the heating and vacuuming are stopped. After a certain period of time, the vacuum is broken by inflating. After the pressure inside and outside the tank is balanced, after a certain period of time (if the shelf is moved out of the tank too early, the glass will crack due to the temperature difference between the inside and outside of the tank), the entire shelf together with the glass and accessories inside is moved out of the tank.

[0003] However, it is difficult to control the temperature consistency of the processed glass on each shelf during the manufacturing process. If the temperature consistency cannot be guaranteed, the product qualification rate will decrease, the output will decrease, and the manufacturing cost will increase. In addition, since a lot of insulating materials are used in the manufacturing process, the material is prone to linting during the production process due to its own material properties. The linting material can easily contaminate the glass vacuum cavity of the processed vacuum glass in a vacuum environment, affecting the product quality. Summary of the invention

[0050] The vacuum glass production line of the present invention adopts a single-piece assembly line production form. Before starting work, according to requirements, one of the tempered glass original sheets that has been tempered is first printed with a liquid phase or a flow-loaded transparent material in an array manner on the upper surface of the tempered glass original sheet by screen printing, and is used as a support after subsequent solidification; the tempered glass original sheet with the printed support is transported to a soldering material distribution platform along a transmission roller, and the soldering material distribution platform computer inputs a nozzle running trajectory according to the known size of the tempered glass original sheet, and sprays the solder through the nozzle on the four sides of the plane of the tempered glass original sheet, so as to be used as a peripheral sealing strip for two tempered glass original sheets in the future; then the tempered glass original sheet with the arranged support and solder is entered into a curing furnace along a transmission roller, and the support and the solder are solidified together on the surface of the tempered glass original sheet.

[0051] The solidified tempered glass original sheet is transported to another platform along the transmission roller through the cooling air duct, and a robot is used to transfer the strip getter in the special strip getter box to the specified position of the solidified tempered glass original sheet and let it fall. Then, another robot is used to transfer another tempered glass original sheet to be combined to the top of the solidified tempered glass original sheet and let it fall. After the two tempered glass original sheets overlap, the robot removes the upper metal frame from the professional tool rack, lays the frame flat on the top of the upper tempered glass original sheet, and makes the edge of the frame overlap with the edge of the tempered glass original sheet. Another special robot is used to clamp the two tempered glass original sheets with ceramic clamps 13 according to the layout requirements, thereby forming a glass assembly 1.

[0052] During operation, the robot grips the glass assembly 1 and places it on the conveying roller 2. Then the glass assembly 1 first moves along the conveying roller 2 to the preheating box 4 for overall preheating. The preheating box uses a heating tube and a fan to circulate air to heat the glass in the glass assembly to the required temperature.

[0053] Specifically, the preheating box 4 includes a first box body 40; a plurality of heating tubes 41 are arranged inside the first box 40, and the plurality of heating tubes 41 are staggered and distributed above and below the glass assembly 1, and there are seven heating tubes 41 located above and below the glass assembly 1, and the heating tubes 41 are used to preheat the tempered glass sheet in the glass assembly 1 as a whole. At the same time, two infrared thermometers 42 for measuring the temperature of the tempered glass sheet are installed above the glass assembly 1; wherein, the number of heating tubes of the heating tubes 41 is set according to the length of the glass running direction, and the heating temperature of the heating tubes is set according to the needs.

[0054] Next, the preheated glass assembly 1 enters the low vacuum degassing box along with the transmission roller 2 through the vacuum valve 3. After the glass assembly passes through the vacuum valve, the vacuum valve is immediately closed, and the low vacuum degassing box is evacuated for standby use; wherein, the low vacuum degassing box includes a second box body 50; a plurality of heating tubes 41 for heating the tempered glass original sheet are arranged in the second box body 50, the heating tubes 41 below the glass assembly are installed between the rollers, the heating tubes above the glass assembly are distributed above the glass assembly, and are installed in a staggered manner with the heating tubes below the glass assembly, and two infrared thermometers 42 for measuring the temperature of the tempered glass original sheet are also arranged above the glass assembly; a vacuum pump 51 and a vacuum gauge 52 are also arranged in the second box body 50; a pneumatic baffle valve 53 is arranged between the vacuum pump 51 and the second box body 50.

[0055] During operation, when the glass components enter the low vacuum degassing box, when the temperature of the glass components reaches the set value through the heating tube, the vacuum equipment of the low vacuum degassing box is turned on to evacuate the box to the set vacuum value, and degas the surface of the glass components under low vacuum. After the initial stage of degassing, the glass components run through the vacuum valve along the transmission roller to the subsequent high vacuum degassing box without breaking the vacuum.

[0056] The low vacuum degassing box 5 and the high vacuum degassing box 6 have the same structure.

[0057] When the glass component 1 enters the high vacuum degassing box 6, the corresponding vacuum valve is immediately closed. Before the glass component enters the high vacuum degassing box, the high vacuum degassing box has been evacuated to a set high vacuum value by the vacuum equipment. The number of heating tubes in the high vacuum degassing box is set according to the length of the glass running direction. The number of tubes that need to be heated is set, and the heating temperature of the heating tube is set according to the needs. When the temperature reaches the set value, the surface of the glass component is continuously degassed under high vacuum. After the high vacuum degassing is completed, the glass component runs through the vacuum valve along the transmission roller to the designated position in the subsequent high vacuum combining box without breaking the vacuum.

[0058] Specifically, the high vacuum sheet-combining box 7 includes a third box body 70; a heating tube 41 for heating the tempered glass original sheet is provided in the third box body 70, and the temperature of the glass is measured by an infrared thermometer 42; an eddy current coil plate 71 located above the glass assembly 1 is provided in the third box body 70; a high vacuum pump group 72 and a compound vacuum gauge 73 are also provided outside the third box body; a pneumatic baffle valve 53 is also provided between the high vacuum pump group 72 and the third box body 70.

[0059] During operation, before the glass components enter the high vacuum combining box, the high vacuum combining box has been evacuated to a set high vacuum value by the vacuum equipment. An eddy current coil plate 71 is installed at a specified position above the transmission roller in the high vacuum combining box, and a heating tube 41 is installed between the rollers. The number of heating tubes of the heat pipe is set according to the length of the tempered glass original sheet in the running direction, and the heating temperature of the heating tube is set according to the needs. The first purpose is to heat the transmission roller to prevent the glass components from contacting the cold transmission roller, and to prevent the glass from cracking due to the temperature difference between the roller and the glass components. The second purpose is to wait for the heated glass component to come over and heat the lower tempered glass original sheet of the glass component to another set temperature, and wait for the glass After the assembly is fully degassed in the high vacuum laminating box, the eddy current coil plate 71 is started, and the magnetic cutting line generated by the eddy current coil plate 71 makes the upper metal frame 12 between the glass and the ceramic clamp fully heated. The heated upper metal frame 12 melts the solder between the two tempered glass original sheets through heat transfer through the glass. During the melting process, combined with the external force of the ceramic clamp, the solder and the two tempered glass original sheets are fully in contact, and the two tempered glass original sheets are combined together; when the temperature on the upper metal frame 12 reaches the set value, the eddy current coil plate 71 stops heating, and the heating tube below stops heating at the same time, and the glass assembly after laminating runs along the transmission roller through the vacuum valve to the specified position in the subsequent vacuum transition cooling box 8.

[0060] As a further preferred embodiment, the vacuum transition cooling box 8 includes a fourth box body 80; a heating tube 41 for heating the tempered glass original sheet is provided in the fourth box body 80, and the temperature of the tempered glass original sheet is measured by an infrared thermometer 42; a high vacuum pump group 72 and a compound vacuum gauge 73 are also provided outside the fourth box body 80; a pneumatic baffle valve 74 is provided between the high vacuum pump group 72 and the fourth box body 80; a cooling water jacket 81 communicating with the interior of the fourth box body 80 is also provided on the outer wall of the fourth box body 80.

[0061] During operation, before the glass components enter the vacuum transition cooling box, the box has been evacuated to a set high vacuum value by vacuum equipment. The box also has heating tubes installed between the rollers and the roller intervals. The number of heating tubes is set according to the length of the glass in the running direction. The number of tubes that need to be heated is set, and the heating temperature of the heating tubes is set according to the needs. The purpose is to heat the rollers to prevent the hot glass components from coming over to contact the cold rollers, thereby preventing the glass from cracking due to temperature differences.

[0062] When the combined glass components enter the vacuum transition cooling box, the pressure in the box is gradually reduced to normal pressure according to the pressure setting value. After the pressure inside and outside the box is balanced, the box continuously extracts the heat generated by the hot air in the box from the box through the cooling water jacket 81 on the outer wall of the box, so that the temperature of the combined glass components gradually decreases. When the temperature of the combined glass components drops to a certain set temperature value, the combined glass components with a certain temperature are run along the conveying roller through the vacuum valve to the designated position of the subsequent normal pressure internal circulation hot air cooling box.

[0063] As a further preferred embodiment, the normal pressure internal circulation hot air cooling box 9 includes a fifth box body 91 with an insulation shell 90; the fifth box body 91 is provided with a heating tube 41 for heating the glass assembly after assembly, and the temperature of the glass assembly after assembly is measured by an infrared thermometer 42; the fifth box body 91 is provided with two air ducts 92 arranged up and down; the two air ducts 92 are communicated with a high temperature resistant axial flow fan 93 arranged outside the fifth box body 91, and the high temperature resistant axial flow fan 93 provides hot air via a hot air generator 94; a high temperature resistant metal butterfly valve 95 is provided between the two air ducts 92 and the high temperature resistant axial flow fan 93.

[0064] During operation, after the glass assembly passes through the vacuum valve, the vacuum valve is immediately closed, and the front box is evacuated and put into standby use. The box is a normal pressure box, and a hot air generator and a high temperature resistant axial flow fan 93 are connected outside the box. When the glass assembly enters the box, the high temperature resistant axial flow fan 93 controls the hot air generator 94 to blow hot air lower than the temperature of the glass assembly into the box, so that the glass assembly is cooled to the set temperature value, and the glass assembly with a certain temperature is run along the transmission roller through the vacuum valve to the designated position in the subsequent normal pressure external circulation air cooling box.

[0065] As a further preferred embodiment, the normal pressure external circulation air cooling box 10 includes a sixth box body 100; the sixth box body 100 is provided with a heating tube 41 for heating the tempered glass original sheet, and the temperature of the glass is measured by an infrared thermometer 42; the sixth box body 100 is provided with two air ducts 92 arranged up and down; the two air ducts 92 are connected to the axial flow fan 101; and an air filter 102 is provided at the air inlet of the axial flow fan 101.

[0066] During operation, after the glass component passes through the vacuum valve, the vacuum valve is immediately closed. The atmospheric pressure external circulation air cooling box 10 is an open atmospheric pressure box, and an axial flow fan 101 is connected outside the box. When the glass component enters the box, the axial flow fan 101 blows air at atmospheric pressure temperature into the box to cool the glass component to the set low temperature value. After the low temperature value is reached, the glass component moves the processed finished vacuum glass to the subsequent platform along the transmission roller, waiting for inspection, packaging and shipment.

In addition, since insulating and heat-insulating materials such as insulating cloth and ceramic plates are not used in this production line, the processed vacuum glass cavity will not be polluted and the equipment will not be damaged during the production process, which greatly improves the overall quality of the product. At the same time, it has the characteristics of simple process, strong operability, energy saving and environmental protection.
