Figure 1 As shown, the glass tempering furnace 1 provided by the present invention may include a frame 11, on which a first furnace body 12, a picking mechanism 13, a second furnace body 14, a third furnace body 15, a transport mechanism 16 and a corresponding control system (not shown) are provided, wherein the first furnace body 12 is used to complete the glass cover plate preheating step and the slow cooling step in the glass tempering process; the picking mechanism 13 is used to pick up and place the tempering cage loaded with the glass cover plate; the second furnace body 14 and the third furnace body 15 are both used to temper the glass cover plate; the transport mechanism 16 is used to carry the first furnace body 12, so as to realize the transport of the tempering cage in the first furnace body 12 to the positions of the second furnace body 14 and the third furnace body 15 respectively.

[0037] It is understandable that, in actual production, a tempered cage can be loaded with thirty to forty tempered racks, and each tempered rack can be loaded with one hundred glass cover plates. Here, the glass cover plate can be specifically a mobile phone glass cover plate.

[0038] The control system provided by the present invention is used to control the first furnace body 12, the picking mechanism 13, the second furnace body 14, the third furnace body 15, and the carrying mechanism 16 accordingly. The specific control may include:

[0039] Action 1: After the temperature inside the first furnace body 12 reaches the first preset temperature, the first set of tempering cages is placed into the first furnace body for preheating by using the pickup mechanism 13. Here, the first preset temperature may be 90 degrees Celsius.

[0040] Action 2: After the temperature inside the first furnace body 12 reaches the second preset temperature and the temperature inside the second furnace body 12 reaches the third preset temperature, the first furnace body 12 is transported to the second furnace body 14 by the transport mechanism 16, and the first set of tempering cages in the first furnace body 12 is placed in the second furnace body 14 by the pick-up mechanism 13 so as to perform tempering treatment on the glass cover plates in the first set of tempering cages by the second furnace body 14. Here, the second preset temperature may be 370 degrees Celsius, and the third preset temperature may be 420 degrees Celsius.

[0041] Action 3: After the temperature in the first furnace body 12 drops to the first preset temperature, the second set of tempered cages loaded with glass cover plates are placed into the first furnace body 12 by using the picking mechanism 13 for preheating.

[0042] Action 4: After the temperature inside the first furnace body 12 reaches the second preset temperature and the temperature inside the third furnace body 15 reaches the third preset temperature, the first furnace body 12 is transported to the third furnace body 15 by the transport mechanism 16, and the picking mechanism 13 places the second group of tempering cages in the first furnace body 12 into the third furnace body 15.

[0043] Action 5: After the second furnace body 15 performs tempering treatment on the glass cover plates in the first group of tempering cages, the first furnace body 12 is transported to the second furnace body 14 by the transport mechanism 16, and the first group of tempering cages in the second furnace body 14 is placed into the first furnace body 12 by the picking mechanism 13 to perform slow cooling treatment on the glass cover plates in the first group of tempering cages.

[0044] Action 6: The first furnace body 12 performs a slow cooling treatment on the glass cover plates in the second group of tempered cages, and after the first group of tempered cages are placed at a preset position by the picking mechanism 13, the first furnace body 12 is transported to the position of the third furnace body 15 by the transport mechanism 16, and the second group of tempered cages in the third furnace body 15 is placed into the first furnace body 12 by the picking mechanism 13 to perform a slow cooling treatment on the glass cover plates in the second group of tempered cages.

[0045] The glass tempering furnace and corresponding action execution provided by the present invention, compared with the traditional method of using two furnace bodies separately to cause the problem of occupying space and more idle time in the tempering process, the present invention uses the first furnace body to realize preheating treatment and slow cooling treatment of the glass cover plate loaded in the tempering cage while meeting normal production requirements to reduce the space occupied by the equipment, and controls the processing coordination between the first furnace body, the second furnace body, and the third furnace body to reduce the idle time of the furnace body, thereby improving the utilization rate of equipment resources.

[0046] In this embodiment, the control system is also used to control:

[0047] Action 7: After the first set of tempered cages are placed at the preset position by the picking mechanism 13, and before the picking mechanism 13 places the second set of tempered cages in the third furnace body 15 into the first furnace body to perform a slow cooling treatment on the glass cover plate, the picking mechanism is used to place the third set of tempered cages into the first furnace body for preheating treatment;

[0048] After the temperature inside the first furnace body 12 reaches the second preset temperature and the temperature inside the second furnace body 14 reaches the third preset temperature, the first furnace body 12 is transported to the position of the second furnace body 14 by the transport mechanism 16, and the third group of tempered cages in the first furnace body 12 is placed in the second furnace body 14 by the picking mechanism 13 so that the glass cover plates in the third group of tempered cages are tempered by the second furnace body 14, thereby realizing the reuse of the first furnace body 12 for preheating treatment and slow cooling treatment, and at the same time, using the time gap of the third furnace body 15 for tempering the glass cover plates in the second group of tempered cages, using the first furnace body 12 to preheat the third group of tempered cages, thereby further reducing the idle time of the first furnace body 12.

[0049] It should be understood that, during the tempering process of the third group of tempering cages in the second furnace body 14, the first furnace body can be brought to the third furnace body by the transport mechanism, and the second group of tempering cages in the third furnace body can be picked up by the picking mechanism to perform a slow cooling process on the glass cover plates in the second group of tempering cages in the first furnace body. Similarly, after the slow cooling, the second group of tempering cages is placed at a preset position, and during the tempering process of the third group of tempering cages in the second furnace body 14, the first furnace body 12 can be used to preheat the fourth group of tempering cages, and so on and so forth for the tempering process of the subsequent groups of tempering cages.

[0050] In this embodiment, the first furnace body 12 may specifically include a first accommodating cavity for placing the tempered cage and a first opening and closing door structure of the first accommodating cavity. The picking mechanism 13 may specifically include a fixing portion provided on the first furnace body 12 and a picker connected to the fixing portion, and the picker is used to pick up the tempered cage or place the picked up tempered cage at a designated position. The second furnace body 14 may specifically include a second accommodating cavity for placing the tempered cage and a second opening and closing door structure of the second accommodating cavity, and the third furnace body 15 may include a third accommodating cavity for placing the tempered cage and a third opening and closing door structure of the third accommodating cavity.

[0051] The transport mechanism 16 includes a guide rail 161 and a carrier 162 disposed on the guide rail 161. The first furnace body 12 is disposed on the carrier 162. The initial transport position of the carrier 162 is located between the second furnace body 14 and the third furnace body 15. Here, the initial transport position is located above the material placement table, and the initial transport position and the material placement table can be further located at the middle position between the second furnace body 14 and the third furnace body 15. Therefore, during the initial operation, the picking mechanism 13 uses a picker to pick up the tempered cage placed on the material placement table and places it into the first accommodating cavity of the first furnace body 12.

[0052] The aforementioned preset position may coincide with the material placement table, or may be arranged below the guide rail outside the material placement table.

[0053] Here, the guide rail 161 includes a first slide rail and a second slide rail arranged in parallel, and the carrier 16 includes a first carrier part arranged on the first slide rail and a second carrier part arranged on the second slide rail. The first carrier part and the second carrier part are fixedly connected to the outer wall of the first furnace body 12, so when the first carrier part and the second carrier part move on the corresponding slide rails, they can drive the first furnace body 12 to achieve displacement.

[0054] It can be understood that when implementing specific actions, the control system can also control the opening and closing of the corresponding opening and closing door structure and the tempering time and temperature. The corresponding control basis, such as the opening and closing of the corresponding opening and closing door structure, can be an electrical signal including position information emitted by a position sensor signal, such as an electrical signal emitted by an optical position sensor or a limit switch; the corresponding tempering time can be an electrical signal including time information emitted by a timing circuit, such as an electrical signal emitted by a timing unit; the corresponding temperature can be an electrical signal including temperature information emitted by a temperature sensor, such as an electrical signal emitted by an electronic thermometer.

[0055] In the actual production process, the controller can simultaneously control the first furnace body 12, the second furnace body 14 and the third furnace body 15 to start heating up. When the temperature inside the first furnace body 12 rises to 90°C, the first opening and closing door structure of the first furnace body 12 opens, and the picking mechanism 13 hoists the mobile phone glass cover plates in the first group of tempered cages into the first furnace body 12. The first opening and closing door structure of the first furnace body 12 is closed to start preheating the mobile phone glass cover plates in the first group of tempered cages.

[0056] After 0.5 hours, the temperature in the first furnace body 12 rises to 370°C, and the preheating treatment is completed after 1 hour. At the same time, if the temperature of the molten salt in the second furnace body 14 and the third furnace body 15 is 420°C, the first furnace body 12 is driven to move toward the second furnace body 14 by the carrier mechanism 16, and stops moving when it moves directly above the second furnace body 14. The second opening and closing door structure of the second furnace body 14 is opened to allow the first group of tempered cages in the first furnace body 12 to be placed in the second accommodating cavity of the second furnace body 14. Thereafter, the second opening and closing door structure of the second furnace body 14 is closed, and the second furnace body 14 performs tempering treatment on the mobile phone glass cover in the first group of tempered cages.

[0057] Afterwards, the transport mechanism 16 drives the first furnace body 12 to move back to the middle position (initial transport position) and starts cooling. After 1 hour, the temperature inside the first furnace body 12 drops to 90°C. The first opening and closing door structure of the first furnace body 12 is opened, and the picking mechanism 13 hoists the second set of tempered cages (which also have mobile phone glass cover plates loaded thereon) into the first accommodating cavity of the first furnace body 12. The first opening and closing door structure of the first furnace body 12 is closed to start preheating the mobile phone glass cover plates in the second set of tempered cages.

[0058] After 0.5 hours, the temperature inside the first furnace body 14 rises to 370°C, and the preheating treatment is completed after 1 hour. The transport mechanism 16 drives the first furnace body 12 to move toward the third furnace body 15, and stops moving when it moves directly above the third furnace body 15. The third opening and closing door structure of the third furnace body 15 is opened to allow the second tempered cage in the first furnace body 12 to be placed in the third accommodating cavity of the third furnace body 15. Thereafter, the third opening and closing door structure of the third furnace body 15 is closed, and the third furnace body 15 tempers the mobile phone glass cover plates in the second group of tempered cages. At this time, the mobile phone glass cover plates in the first group of tempered cages in the second furnace body 14 are tempered for 2.5 hours, as shown in Table 1, tempering parameter table for conventional material products:

[0059]

[0060] It can be seen from the table that the time required for tempering is 4 hours, so after 1.5 hours, the mobile phone glass cover plates in the first group of tempered cages in the second furnace body 14 are tempered. After that, the transport mechanism 16 drives the first furnace body 12 to move toward the second furnace body 14, and stops moving when it moves to the top of the second furnace body 14. The second opening and closing door structure of the second furnace body 14 is opened, and the picking mechanism 13 hoists the tempered cage loaded with the mobile phone glass cover plates in the first group of tempered cages in the second furnace body 14 into the first furnace body 12 to perform a slow cooling treatment on the mobile phone glass cover plates.

[0061] The transport mechanism 16 drives the second furnace body 12 to move, and stops moving when it moves to the initial transport position, and the first opening and closing door structure of the first furnace body 12 is closed, and the slow cooling treatment is completed after 1 hour. After the slow cooling treatment is completed, the first opening and closing door structure of the first furnace body 12 is opened, and the first group of tempered cages with mobile phone glass cover plates after the slow cooling treatment are placed on the material placement table by the picker 13, completing the tempering process of the mobile phone glass cover plates in the first group of tempered cages.

[0062] Afterwards, the picking mechanism 13 hoists the third set of tempered cages loaded with the mobile phone glass cover plate into the first furnace body 12 to perform the same tempering steps as the preheating treatment in the first furnace body 12, the tempering treatment in the second furnace body 14, and the slow cooling treatment in the first furnace body 12, and when the third set of tempered cages is placed in the second furnace body 14 to temper the mobile phone glass cover plate loaded on the second set of tempered cages, the mobile phone glass cover plate in the third furnace body 15 is tempered for 4 hours, and the tempering treatment is completed. Thereafter, the transport mechanism 16 drives the first furnace body 12 to move toward the third furnace body 15, and stops moving when it moves to the top of the third furnace body 15. The third opening and closing door structure of the third furnace body 15 is opened, and the picking mechanism 13 hoists the second set of tempered cages loaded with the mobile phone glass cover plate in the third furnace body 15 into the first furnace body 12 to perform slow cooling treatment on the mobile phone glass cover plate, and the slow cooling treatment is completed after 1 hour. Afterwards, the first opening and closing door structure of the first furnace body 12 is opened, and the second set of tempered cages equipped with mobile phone glass cover plates after slow cooling are placed on the loading platform by the picker 13, completing the tempering process of the mobile phone glass cover plates in the second set of tempered cages. It can be seen that the first furnace body 12 is effectively reused according to the time of each treatment to implement the preheating and slow cooling steps, while still meeting the production requirements, reducing the idle time of the equipment, improving the utilization rate of equipment resources, and reducing the space occupied by the equipment.

[0063] In the glass tempering furnace provided by the present invention, an air flow passage for connecting with the air delivery channel of the gas delivery device is opened on the wall of the first accommodating chamber of the first furnace body, and the air flow passage is used to input heat-conducting gas of a first preset temperature into the first accommodating chamber during preheating treatment, and to input heat-conducting gas of a second preset temperature into the first accommodating chamber during slow cooling treatment.

[0064] Among them, the gas supply device is used to provide heat-conducting gas at a preset temperature. By inputting heat-conducting gas of corresponding temperature, the temperature effect on the glass cover plate can be enhanced, effectively shortening the processing time of preheating and slow cooling of the first furnace body, and improving production efficiency.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
