DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0025] The laminating furnace is a device that bonds two or more pieces of glass together by means of high-temperature extrusion. In current laminating furnace devices, the heating components are usually arranged in the center of the furnace. However, this will result in uneven heat distribution in the heating area inside the furnace, which will further cause excessive temperature differences in different areas of the product during processing in the furnace, seriously affecting the product quality.

[0026] Based on the above problems, please refer to Figure 1 , an embodiment of the present application provides a laminating processing device 1, which may include: a furnace body 10, a heating module 20, a pumping module 30, a processing platform 40, a heat convection module 50, and a controller (not shown in the figure).

[0027] Specifically, please continue to refer to Figure 1 , the furnace body 10 may serve as the base of the laminating processing device 1. A processing cavity 140 may be formed inside the furnace body 10, and the processing cavity 140 may be used for heating and processing workpieces. The processing cavity 140 has an inner wall, and the inner wall may include: a top wall 110, a bottom wall 120, and a side wall 130. The top wall 110 and the bottom wall 120 are oppositely arranged, and the side wall 130 is annular, such as a circular ring or a square ring, etc., which is not limited herein and may be specifically set according to actual situations.

[0028] In this embodiment, the furnace body 10 may be supported by materials with certain strength and heat insulation properties, such as: refractory fiber, ceramic fiber, and stainless steel, etc. Refractory fiber has the characteristics of light weight, high strength, high fire resistance, and good heat insulation performance, and can effectively maintain the temperature inside the furnace body 10. Ceramic fiber has excellent heat insulation performance and fire resistance, can withstand high temperatures, and can effectively prevent heat dissipation. Stainless steel has high strength, good heat insulation performance and fire resistance, can withstand high temperatures, and can effectively prevent heat dissipation, which can be specifically selected according to actual situations and is not limited herein.

[0029] Please continue to refer to Figure 1, in the embodiments of the present application, taking the side wall 130 as a square ring as an example for illustration, the side wall 130 may include a first side wall 131 and a second side wall 132. The first side wall 131 and the second side wall 132 are arranged opposite to each other, and the heights of the first side wall 131 and the second side wall 132 are the same. The top wall 110 and the bottom wall 120 are respectively connected to the opposite ends of the first side wall 131 and the second side wall 132. Both the first side wall 131 and the second side wall 132 are perpendicular to the top wall 110, and both the first side wall 131 and the second side wall 132 are perpendicular to the bottom wall 120. The top wall 110, the bottom wall 120, and the side wall 130 enclose a processing chamber 140.

[0030] The heating module 20 may be disposed in the processing chamber 140 for heating the processing chamber 140. The embodiments of the present application do not limit the specific position of the heating module 20. For example, as Figure 1 shown, the heating module 20 may be disposed on the inner wall of the processing chamber 140.

[0031] Furthermore, the heating module 20 may include a heating tube 210 and a temperature sensor 220. The heating tube 210 may be disposed on the inner wall of the processing chamber 140. Specifically, the heating tube 210 and the temperature sensor 220 may be provided on the top wall 110, the bottom wall 120, the first side wall 131, and the second side wall 132. After being powered on, the heating tube 210 can generate heat to process the workpiece. The temperature sensor 220 can be used to monitor the temperature in the processing chamber 140, so that it is convenient for the user to more intuitively understand the temperature situation in the processing chamber 140 and can control the temperature in the processing chamber 140 according to the above temperature situation. If the user detects that the temperature in the processing chamber 140 is too high, the heating tube 210 can be turned off for cooling, etc.

[0032] Please also refer to Figure 1 and Figure 2 , in some embodiments, the heating tube 210 may be configured into multiple heating regions. For example, the heating tube 210 disposed on the top wall 110 may be configured as a top wall region 71, the heating tube 210 disposed on the first side wall 131 may be configured as a first side wall region 72, the heating tube 210 disposed on the second side wall 132 may be configured as a second side wall region 73, and the heating tube 210 disposed on the bottom wall 120 may be configured as a bottom wall region 74.

[0033] The temperature sensor 220 disposed on the top wall 110 is used to obtain the temperature of the top wall region 71 and its vicinity. The temperature sensor 220 disposed on the first side wall 131 is used to obtain the temperature of the first side wall region 72 and its vicinity. The temperature sensor 220 disposed on the second side wall 132 is used to obtain the temperature of the second side wall region 73 and its vicinity. The temperature sensor 220 disposed on the bottom wall 120 is used to obtain the temperature of the bottom wall region 74 and its vicinity.

[0034] In this embodiment, the heating tubes 210 located in different heating regions can be respectively connected to the controller. That is to say, in this embodiment, the controller can independently control the heating tubes 210 in multiple heating regions to adjust the output power according to the temperatures near the multiple heating regions. This can further facilitate the user to control the temperature in the processing chamber 140, and then can more easily adjust the temperature in the processing chamber 140, so that the temperature in the processing chamber 140 is in an average state.

[0035] In some embodiments, the controller can also set multiple different partitions. The user can perform zonal modular control on the controllers set in different regions according to the different positions where the heating tubes 210 and the temperature sensors 220 are located. Specifically, when the temperature in a certain heating region is too low or too high, the heating tubes 210 in that region can be adjusted separately. In this way, it will not affect the whole, and thus can effectively ensure the temperature uniformity, and at the same time save electricity costs.

[0036] Please refer to again Figure 1 , the processing platform 40 can be arranged in the processing chamber 140. The processing platform has a placement cavity 421. The processing platform 40 can be used to carry workpieces and provide support for the processing of workpieces. Specifically, the processing platform 40 has a placement cavity 421, and the placement cavity 421 can be used to load workpieces.

[0037] In this embodiment, the processing platform 40 can include: a slide rail 410 and a placement bag 420.

[0038] The slide rail 410 can be arranged on the inner wall of the processing chamber 140, specifically on the bottom wall 120. The placement bag 420 can be slidably arranged on the slide rail 410. The interior of the placement bag forms a placement cavity 421. The user can place the workpiece in the placement cavity 421, and then the placement cavity 421 can enter the designated position in the processing chamber 140 through the slide rail 410 to process the workpiece. When the workpiece is processed, the placement bag 420 can slide out through the slide rail 410 to facilitate the user to replace the workpiece. The arrangement of the slide rail 410 can make it more convenient for the user to load and unload workpieces.

[0039] In this embodiment, the placement bag 420 can be composed of a silica gel bag and an internal grid fiberglass cloth. In this embodiment of the application, taking the placement bag 420 as a silica gel bag as an example, the workpiece is placed in the placement cavity 421 in the placement bag 420. The placement bag 420 has good elasticity. Under the action of negative pressure, the placement bag 420 can promote the shaping of the workpiece. In some other embodiments, the placement bag 420 can also be made of other high-temperature resistant materials, such as ceramic fiber, etc., which are not limited here and can be specifically selected according to the actual situation.

[0040] Please refer to simultaneously Figure 1 andFigure 3 The air extraction module 30 can be used to provide negative pressure to the placement cavity 421 to facilitate shaping of the workpiece. In this embodiment, the air extraction module 30 can include: an air extraction pipeline 310 and an air extraction pump 320.

[0041] One end of the air extraction pipeline 310 can be communicated with the inside of the placement cavity 421, and the other end extends outside the processing cavity 140 to conduct the inside and outside of the placement cavity 421. The specific shape and material of the air extraction pipeline 310 are not limited in the embodiments of the present application. The air extraction pipeline 310 can be made of the same material as the furnace body 10. For specific details, reference can be made to the relevant description of the furnace body 10, which will not be elaborated here.

[0042] The air extraction pump 320 is connected to the air extraction pipeline 310. The air extraction pump 320 is arranged on one side of the furnace body 10. The air extraction pump 320 can be used to extract air from the air extraction pipeline 310 to reduce the air pressure in the processing cavity 140.

[0043] Further, in some embodiments, the air extraction module 30 can further include: a throttle valve 330. The throttle valve 330 is arranged on the air extraction pipeline 310. The throttle valve 330 is used to control the flow rate of the air extraction pipeline 310, which can facilitate the user to adjust the air pressure in the processing cavity 140. In addition, the setting of the throttle valve 330 can affect the air density passing through the air extraction pipeline 310 per unit time.

[0044] In this embodiment, the user can control the rotation speed of the air extraction pump 320 through the controller, thereby affecting the air flow rate in the air extraction pipeline 310, so as to adjust the speed of the air extraction rate. At the same time, the user can also control the throttle valve 330 through the controller to change the air density passing through the air extraction pipeline 310 per unit time. In this way, the dual control of the throttle valve 330 and the air extraction pump 320 can be used to change the effect of the air extraction rate, so that the air pressure in the processing cavity 140 is more suitable for processing the workpiece, and thus it is beneficial to improve the quality of the workpiece.

[0045] Please also refer to Figure 4 and Figure 5 The heat convection module 50 can be arranged on the inner wall of the furnace body 10 and located in the processing cavity 140. The perpendicular direction of the air outlet direction of the heat convection module 50 and the inner wall where the heat convection module 50 is arranged has an angle greater than 0° and less than 90°.

[0046] It should be noted that the air outlet direction of the above heat convection module 50 refers to the main flow direction of the air flow generated by the heat convection module 50. For specific details, reference can be made to Figure 4 and Figure 5 the direction pointed by the solid arrows in the processing cavity 140.

[0047] This can make the temperature of each area of the product on the processing platform 40 in the processing chamber 140 more uniform and meet the requirement of ±3°C. Furthermore, it can make the temperature received by the workpiece arranged on the processing platform 40 more uniform. Finally, the quality of the workpiece can be controlled, improving the quality of the workpiece.

[0048] It should be noted that the specific structure of the heat convection module 50 is not limited in the embodiments of the present application. For example, it can be a fan or the like to provide air flow. In this embodiment, the heat convection module 50 can be arranged on the first side wall 131, and the height of the heat convection module 50 is greater than the height of the processing platform 40. In this way, the obstruction effect of the processing platform 40 on the air flow provided by the heat convection module 50 can also be reduced, which is beneficial to promoting the air flow in the processing chamber 140.

[0049] It can be understood that according to the convective heat transfer quantity Q = convective heat transfer coefficient α × convective heat transfer area F × (wall temperature Tw - fluid temperature Tf), the larger the convective heat transfer area F, the larger the convective heat transfer quantity Q. Therefore, in this embodiment, the convective heat transfer quantity Q can be increased by increasing the convective heat transfer area F.

[0050] Specifically, please refer to Figure 4 and Figure 5 , in this embodiment, the included angle between the perpendicular direction of the air outlet direction of the heat convection module 50 and the inner wall where the heat convection module 50 is arranged is defined as a, and the height of the side wall 130 is defined as H 1 , the height of the setting point of the heat convection module 50 is defined as H 2 , specifically, in this embodiment, the heat convection module 50 is arranged on the first side wall 131 of the side wall 130. Therefore, the height of the first side wall 131 is also H 1 , the length of the top wall 110 is defined as L, where a, H1, H2, and L satisfy: tan a = (H 1 -H 2 ) / L / 2. This can ensure the maximum convective heat area F, and further ensure the temperature uniformity of each position of the workpiece.

[0051] In addition, according to the convective heat transfer coefficient of air hc = empirical coefficient B × air flow velocity V ^ velocity exponent n, the faster the air flow velocity V, the larger the convective heat transfer coefficient of air hc, and the overall temperature difference will be smaller, which can better achieve the effect of heat circulation.

[0052] Please continue to refer to Figure 4 and Figure 5 , therefore, in some embodiments, the heat convection module 50 can include: a heat convection wind power system 510 and a flow guide member 520. The flow guide member 520 has a heat circulation curved surface 521, and the heat circulation curved surface 521 can be used to reduce wind resistance and increase the flow velocity of the wind.

[0053] Specifically, the flow guide member 520 can be disposed at the connection between the top wall 110 and the first side wall 131 and at the connection between the second side wall 132 and the bottom wall 120. The center of the thermal circulation curved surface 521 is located on the side of the flow guide member 520 close to the geometric center of the processing chamber 140. When the air flow reaches the thermal circulation curved surface 521 under the guiding action of the thermal convection wind power system 510, the air flow will turn. The specific turning direction of the air flow can be referred to Figure 4 as shown by the dashed circular arrow in the processing chamber 140 in the figure. The structure of the above-mentioned thermal circulation curved surface 521 can conform to the turning direction of the air flow, which can play a role in reducing wind resistance and increasing the flow velocity of the wind.

[0054] Furthermore, in some embodiments, the thermal convection wind power system 510 may include: a first convection module 511 and a second convection module 512. Both the first convection module 511 and the second convection module 512 are disposed on the side wall 130. Specifically, the first convection module 511 can be disposed on the first side wall 131, and the second convection module 512 can be disposed on the second side wall 132, and the air outlet directions of the first convection module 511 and the second convection module 512 are opposite. Specifically, please refer to Figure 4 as shown in the figure. The air outlet direction of the first convection module 511 can be an obliquely upward direction and point to the direction of the top wall 110 and the second side wall 132. The air outlet direction of the second convection module can be an obliquely downward direction and point to the direction of the bottom wall 120 and the first side wall 131. This can make the air outlet direction of the second convection module 512 the same as the air flow direction passing through this place, thereby further increasing the flow velocity of the wind, and further better achieving the effect of thermal circulation. Finally, it can reduce the temperature difference in the processing chamber 140, make the temperature in the processing chamber 140 more uniform, and facilitate the processing of workpieces.

[0055] Furthermore, the first convection module 511 and the second convection module 512 are centrosymmetric with respect to the geometric center of the processing chamber 140, which can further promote the air flow in the processing chamber 140, make the air flow velocities at various places in the processing chamber 140 tend to be the same, and further better achieve the effect of thermal circulation. Finally, it can reduce the temperature difference in the processing chamber 140, make the temperature in the processing chamber 140 more uniform, and facilitate the processing of workpieces.

[0056] In summary, for the laminated processing device 1 provided by the embodiment of the present application, by arranging a heating module 20 and an air extraction module 30 in the processing cavity 140 of the furnace body 10, the controller controls the heating module 20 and the air extraction module 30 to work to process the workpiece placed in the placement cavity 421, and a heat convection module 50 is arranged to adjust the temperature distribution in the processing cavity 140, and an included angle greater than 0° and less than 90° is formed between the air outlet direction of the heat convection module 50 and the inner wall where the heat convection module 50 is arranged. The controller controls the heat convection module 50 to work to make the temperatures at various places in the processing cavity 140 more uniform, avoiding too large a temperature difference between different regions in the processing cavity 140, and thus the workpiece can be heated more uniformly in each region, improving the quality of the workpiece.
