DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The laminating machine is often used to attach the strip material to the film-attached part in the photovoltaic module. In some process requirements, before attaching the strip material, the laminating machine needs to quickly heat the strip material to a desired temperature range.

[0029] In the prior art, the film laminating machine often uses a hot air gun to heat the strip material. During the film laminating process, the hot air gun blows hot air to the strip material while the film laminating machine attaches the heated strip material to the object to be filmed. When the film is attached to the end, the hot air gun stops blowing, the film laminating machine stops attaching, and the cutting device cuts the strip material. Then, the hot air gun continues to blow hot air to the end of the cut unheated strip material, and the film laminating machine finishes attaching the end of the strip material.

[0030] However, when the cutting device cuts the strip material, the hot wire of the hot air gun is still at a high temperature, and the gas in the hot air gun continues to heat up. Therefore, after the strip material is cut, when the hot air gun continues to blow hot air to the strip material, the temperature of the hot air often exceeds the desired temperature range, causing the strip material to overheat. When the film is applied, bubbles are likely to appear at the end of the strip material, resulting in poor film application and affecting the quality of film application.

[0031] In view of the above problems, the present application provides a hot air device and a film laminating machine. The specific structures of the hot air device and the film laminating machine are described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Figure 1 Shown is a schematic structural diagram of a film laminating machine provided in one embodiment of the present application. Figure 2 The present invention provides an embodiment of the present invention. Figure 1 The cross-sectional structural schematic diagram of the film laminating machine along AA is shown. Figure 3 Shown is a schematic structural diagram of a film laminating machine provided in another embodiment of the present application. Figure 4 The present invention provides an embodiment of the present invention. Figure 1 The cross-sectional structure diagram of the film laminating machine along line BB is shown in FIG. Figures 1 to 4 As shown, the hot air device 10 is applied to the film laminating machine 1. The film laminating machine 1 includes the hot air device 10 and the film laminating device 20. The film laminating device 20 includes a film laminating head 21. The film laminating device 20 is used to attach the strip material 40 passing through the film laminating head 21 to the object to be film-laminated. The hot air device 10 includes: a first air channel 11, a second air channel 12 and a heating component 13.

[0033] The first air channel 11 has a first air inlet 110 and a first air outlet 111, and includes a first air channel section 112 and a second air channel section 113 that are connected in sequence along the direction from the first air inlet 110 to the first air outlet 111. The first air inlet 110 is configured to receive the first gas. The first air outlet 110 is used to blow air toward the film laminating head 21.

[0034] The second gas channel 12 has a second gas inlet 120 and a second gas outlet 121. The second gas inlet 120 is configured to receive the second gas. The second gas outlet 121 is in communication with the second gas channel section 113.

[0035] The heating assembly 13 is configured to heat the first gas flowing through the first gas channel segment 112 .

[0036] Exemplarily, the first air passage 11 and the second air passage 12 may be two parts of the same component, or may be formed by different components.

[0037] Exemplarily, the first air duct 11 can be integrally formed or composed of multiple parts. The first air duct section 112 and the second air duct section 113 can be two parts of the same part, or can be formed by different parts. In this embodiment, the first air duct 11 is formed by splicing multiple tubular parts, and the first air duct section 112 and the second air duct section 113 are formed by different tubular parts, so that the heating component 13 can heat the first gas flowing through the first air duct section 112 separately.

[0038] The second air duct 12 can be integrally formed or composed of multiple parts. In this embodiment, the second air duct 12 and the second air duct segment 113 are integrally formed, thereby avoiding the need for the second air duct 12 to be assembled separately.

[0039] Exemplarily, the heating component 13 can be any structure capable of heating the first gas flowing through the first air duct section 112. Exemplarily, the heating component 13 can heat the first gas flowing through the first air duct section 112 by heating the first air duct section 112. Exemplarily, the heating component 13 can also directly contact the gas flowing through the first air duct section 112 to heat the gas. For example, the heating component 13 extends into the first air duct section 112. In this way, the first gas can fully contact the heating component 13 to quickly heat the first gas. The heating component 13 can include a resistance wire heating component or a ceramic heating component, etc. For example, the ceramic heating component can include a ceramic heating rod or a ceramic heating tube.

[0040] The types and temperatures of the first gas and the second gas can be set according to actual needs. The second gas can be any gas that can cool the heated first gas. For example, the first gas and the second gas can both be air at room temperature.

[0041] Specifically, the film laminating head 21 can be used as a specific actuator for attaching the strip material 40 to the object to be film-laminated. Exemplarily, the film laminating head 21 can include a roller or other pressure device for applying a certain pressure during the film laminating process to ensure that the strip material 40 is in full contact with the object to be film-laminated to achieve a flat effect. Exemplarily, the film laminating head 21 is disposed on a side of the hot air device 10 having the first air outlet 110, so that the first air outlet 110 can blow air toward the film laminating head 21.

[0042] Exemplarily, the strip material 40 may include a strip film or a film strip. For example, the strip material 40 may include a reflective film. Exemplarily, the part to be filmed may include a component for a photovoltaic module or a semi-finished product for forming a photovoltaic module. For example, the part to be filmed may include glass, a frame, etc. for forming a photovoltaic module. The part to be filmed may be specifically arranged according to actual needs.

[0043] In some application scenarios, when the film laminating machine 1 attaches the strip material 40 to the object to be film-laminated, the hot air device 10 blows hot air to the strip material 40 while the film laminating device 20 attaches the heated strip material 40 to the object to be film-laminated. When the film is laminating to the end, the hot air device 10 stops blowing air, the film laminating device 20 stops laminating, and the strip material 40 is cut. Exemplarily, before the strip material 40 is cut, the second gas is not introduced into the second air channel 12. After the first gas flows through the first air channel section 112 and is heated by the heating component 13, it flows through the second air channel section 113 alone and flows out from the first air outlet 111, blowing toward the strip material 40. After the strip material 40 is cut, when the hot air device 10 continues to blow hot air to the strip material 40 to heat the end of the strip material 40, the second gas is introduced into the second air channel 12, and the second gas flows into the second air channel section 113 from the second air outlet 121. The first gas flows through the first air channel section 112 and is heated by the heating component 13. The second gas and the heated first gas are mixed in the second air channel section 113 to form a mixed gas. The mixed gas flows out from the first air outlet 111. The second gas can cool down the heated first gas, which can prevent the temperature of the gas blown out by the hot air device 10 from being too high, thereby preventing the strip material 40 from overheating.

[0044] In some application scenarios, a temperature sensor is provided at the gas outlet of the first gas channel section 112 to detect the temperature of the heated first gas. When the temperature of the heated first gas is too high, the second gas can be introduced into the second gas channel 12 to reduce the temperature of the heated first gas, thereby preventing the temperature of the gas blown out by the hot air device 10 from being too high, thereby preventing the strip material 40 from overheating. The timing of introducing the second gas into the second gas channel 12 can be set according to actual needs, and this embodiment does not specifically limit it.

[0045] The hot air device 10 provided in this embodiment includes a first air duct 11, a second air duct 12 and a heating component 13. The first air duct 11 includes a first air duct section 112 and a second air duct section 113 that are connected in sequence along the direction from the first air inlet 110 to the first air outlet 111. The heating component 13 is used to heat the gas flowing through the first air duct section 112. The second air outlet 121 of the second air duct 12 is connected to the second air duct section 113. The first gas is heated by the heating component 13 when flowing through the first air duct section 112. The heated first gas can flow into the second air duct section 113, and the second gas can also flow into the second air duct section 113 and mix with the heated first gas. The temperature of the introduced second gas can be lower than the temperature of the third gas, so that the second gas can cool the heated first gas quickly to prevent the temperature of the gas blown out by the hot air device 10 from being too high, thereby avoiding overheating of the strip material 40, which is beneficial to improving the film pasting effect and film pasting quality.

[0046] In addition, such a configuration can also prevent the heated first gas from being overheated, causing thermal damage to the structure after the first airway section 112 along the flow path of the heated first gas, which is beneficial to extending the service life of the hot air device 10.

[0047] In some embodiments, the first gas can enter the first air channel section 112 from the first air inlet 110, and the first gas flowing through the first air channel section 112 is heated by the heating component 13 to form a third gas. The third gas flows into the second air channel section 113, and the second gas can enter the second air channel 12 from the second air inlet 120 and flow into the second air channel section 113 from the second air outlet 121, so that the second gas and the third gas are mixed to form a fourth gas. The fourth gas flows out from the first air outlet 111. The temperature of the second gas is lower than that of the third gas.

[0048] Specifically, when the first gas flows through the first air channel section 112, it is heated by the heating component 13 to form a third gas, and the third gas can flow into the second air channel section 113, and the second gas can also flow into the second air channel section 113 and mix with the third gas. Since the temperature of the second gas introduced can be lower than the temperature of the third gas, the second gas can quickly cool the third gas to form a fourth gas, so as to prevent the temperature of the gas blown out by the hot air device 10 from being too high, thereby avoiding overheating of the strip material 40, which is conducive to improving the film pasting effect and film pasting quality.

[0049] Figure 5 Shown is a schematic structural diagram of a hot air device provided in one embodiment of the present application.

[0050] In some embodiments, the hot air device 10 further includes: a first control valve 14 and a second control valve 15 .

[0051] The first control valve 14 is connected to the first air passage section 112 and is configured to close or open the first air passage section 112. The second control valve 15 is connected to the second air passage 12 and is configured to close or open the second air passage 12.

[0052] The second control valve 15 is further configured to open the second air passage 12 when the first air passage section 112 is opened.

[0053] Exemplarily, the first control valve 14 and the second control valve 15 can be any valve capable of closing or opening the airway. Exemplarily, the first control valve 14 and the second control valve 15 can be a combination of one or more of a solenoid valve, a proportional valve, a stop valve, a ball valve, a butterfly valve, a plug valve and a check valve.

[0054] Exemplarily, the valve of the first control valve 14 is disposed at the air inlet of the first air passage section 112. The valve of the second control valve 15 may be disposed at the second air inlet 120 of the second air passage 12.

[0055] Exemplarily, the second control valve 15 can change the opening degree of the second gas channel 12 to control the flow rate of the second gas, so as to control the temperature of the mixed gas formed by the second gas and the heated first gas.

[0056] The hot air device 10 provided in this embodiment also includes a first control valve 14 and a second control valve 15. The first control valve 14 is used to close or open the first air duct section 112, and the second control valve 15 is used to close or open the second air duct 12. When the first air duct section 112 is opened, the second control valve 15 opens the second air duct 12, so that after the first gas is heated, the second gas can pass through the second control valve 15 and pass into the second air duct section 113 from the second air outlet 121 of the second air duct 12, and mix with the heated first gas, so as to quickly cool the heated first gas and form a mixed gas with a suitable temperature.

[0057] In some embodiments, Figure 5 As shown, the hot air device 10 further includes: a flow meter 16. The flow meter 16 is connected to the second air channel 12 and is configured to detect the amount of the second gas flowing through the second air channel 12. By setting the flow meter 16, when the second gas is introduced into the second air channel 12, the amount of the second gas flowing through the second air channel 12 can be detected, so as to more accurately control the degree of cooling of the heated first gas by the second gas, thereby preventing the temperature of the mixed gas blown out by the hot air device 10 from being too high or too low, thereby preventing the strip material 40 from being overheated or not being heated to the desired temperature, which is beneficial to improving the film pasting effect and film pasting quality.

[0058] For example, the flow meter 16 may include one or a combination of a differential pressure flow meter, a turbine flow meter, an ultrasonic flow meter, and a positive displacement flow meter.

[0059] In some embodiments, Figure 2 As shown, the air inlet 1130 of the second air duct section is close to the first air duct section 112, and the air outlet 1131 of the second air duct section is close to the first air outlet 111. The cross-sectional area of ​​the air inlet 1130 of the second air duct section is larger than the cross-sectional area of ​​the air outlet 1131 of the second air duct section. The cross-sectional area of ​​the air inlet 1130 of the second air duct section is larger, which is conducive to the heated first gas entering the second air duct section 113, and the cross-sectional area of ​​the air outlet 1131 of the second air duct section is smaller, which is conducive to the third gas or the mixed gas formed by the second gas and the heated first gas to flow out more concentratedly, so that the heat is more concentrated, avoiding heating of unnecessary areas, and is conducive to improving heating efficiency.

[0060] In some embodiments, Figure 2As shown, the first airway segment 112 and the second airway segment 113 are assembled and connected to form the first airway 11. The first airway segment 112 and the second airway segment 113 can be connected by plugging, snapping, screwing, bonding or welding. Exemplarily, a sealing ring 17 is provided at the connection between the first airway segment 112 and the second airway segment 113 to improve the sealing of the connection between the first airway segment 112 and the second airway segment 113.

[0061] In some embodiments, Figure 2 As shown, along the direction from the air inlet 1130 of the second air duct segment to the air outlet 1131 of the second air duct segment, the second air duct segment 113 sequentially includes: a constant diameter segment 1132 and a variable diameter segment 1133 .

[0062] The equal diameter section 1132 is connected to the first airway section 112. The air inlet of the equal diameter section 1132 is connected to the first airway section 112. The air inlet of the variable diameter section 1133 is connected to the air outlet of the equal diameter section 1132. The cross-sectional area of ​​the air inlet of the variable diameter section 1133 is greater than the cross-sectional area of ​​the air outlet of the variable diameter section. By providing the equal diameter section 1132, the second airway section 113 and the first airway section 112 are easily connected or assembled, and the variable diameter section 1133 is used to realize the centralized outflow of the heated first gas or mixed gas.

[0063] In some embodiments, the second gas outlet 121 of the second gas channel 12 is connected to the equal diameter section 1132 to fully mix the second gas and the heated first gas in a larger space, and the mixed gas formed by the two flows out more concentratedly from the variable diameter section 1133.

[0064] In some embodiments, the hot air device 10 further includes an air outlet 18 .

[0065] The air outlet head 18 is detachably connected to the second air duct section 113. The air outlet head 18 has a first air duct 180 that runs through the air outlet head 18. One end of the first air duct 180 is in communication with the air outlet 1131 of the second air duct section, and the other end of the first air duct 180 is configured to blow air toward the film laminating head 21. By providing a detachable air outlet head 18, it is convenient for the hot air device 10 to replace the air outlet head 18 with different sizes of the first air duct 180, so that the hot air device 10 can be used to heat strip materials 40 of various widths, thereby improving the convenience and applicability of the hot air device 10.

[0066] Exemplarily, a second sealing ring 19 is provided at the connection between the air outlet head 18 and the second air duct section 113 to improve the sealing performance of the connection between the air outlet head 18 and the second air duct section 113 .

[0067] In some embodiments, the fourth gas flows out from the other end of the first air duct 180 .

[0068] In some embodiments, the first air duct 180 of the air outlet 18 is smaller in size. In this case, the cross-sectional area of ​​the air inlet 1130 of the second air duct section can be larger than the cross-sectional area of ​​the air outlet 1131 of the second air duct section. In this way, the mixed gas is more easily gathered into the first air duct 180 and blown out.

[0069] In some embodiments, the second airway segment 113 includes a first sub-airway segment 1134 and a second sub-airway segment 1135 .

[0070] The first sub-air duct segment 1134 is connected to the first air duct segment 112. The second sub-air duct segment 1135 is connected to the first sub-air duct segment 112 and the first air duct 180. The extension direction of the first sub-air duct segment 1134 is arranged crosswise with the extension direction of the second sub-air duct segment 1135. In other words, the extension direction of a section of the second air duct segment 113 connected to the first air duct segment 112 and the extension direction of a section of the second air duct segment 113 connected to the first air duct 180 are arranged crosswise, so that the second air duct segment 113 can be in a zigzag shape, so that the length of the second air duct segment 113 along the extension direction of the first sub-air duct segment 1134 can be designed to be shorter, which is conducive to reducing the space occupied by the hot air device 10 along the extension direction of the first sub-air duct segment 1134.

[0071] For example, Figure 2 As shown, the extension direction of the first sub-airway segment 1134 is set at 90° to the extension direction of the second sub-airway segment 1135. Exemplarily, the extension direction of a section of the first air duct 180 located at the air outlet of the air outlet head 18 is the same as the extension direction of the first sub-airway segment 1134.

[0072] In some embodiments, the first gas and the second gas are provided by a gas source assembly ( Figures 1 to 5 The hot air device 10 may further include: a first joint 30.

The first heat insulation board 32 is arranged between the heating component 13 and the film sticking device 20, and there is a gap a between the first heat insulation board 32 and the heating component 13. This arrangement allows the first heat insulation board 32 to separate the film sticking device 20 and the heating component 13 that generates heat, and because there is a gap a between the first heat insulation board 32 and the heating component 13, air insulation can be used between the first heat insulation board 32 and the heating component 13 to prevent the heat emitted by the heating component 13 from damaging the film sticking device 20, which is beneficial to extending the service life of the film sticking device 20, and is beneficial to heat preservation of the hot air device 10 and reducing energy loss.

[0080] In some embodiments, the hot air device 10 further includes: at least one second heat insulation board 33. The second heat insulation board 33 is arranged above the heating assembly 13.

[0082] The above describes in detail the embodiment of the hot air device 10 of the present application, and the following describes in detail the embodiment of the film laminating machine 1 of the present application. It should be understood that the description of the embodiment of the hot air device 10 corresponds to the description of the embodiment of the film laminating machine 1, so the parts not described in detail can refer to the previous embodiment of the hot air device 10.

[0083] like Figure 1 As shown, an embodiment of the present application provides a film laminating machine 1. The film laminating machine 1 includes a film laminating device 20 and a hot air device 10 mentioned in any of the above embodiments.

[0084] The film sticking device 20 includes a film sticking head 21. The film sticking device 20 is configured to stick the strip material 40 passing through the film sticking head 21 to the object to be stuck. The first air outlet 111 of the hot air device 10 is configured to blow air toward the film sticking head 21.

[0085] Specifically, the first air outlet 111 blows hot air toward the film laminating head 21 to heat the strip material 40 passing through the film laminating head 21. Exemplarily, the first air outlet 111 may also be configured to blow air toward the strip material 40 passing through the film laminating head 21.

[0086] The film laminating machine 1 can be used to laminat film on a film-laminating object. Exemplarily, the hot air device 10 is arranged on the film laminating device 20.

The first gas is heated by the heating component 13 when flowing through the first air duct section 112. The heated first gas can flow into the second air duct section 113, and the second gas can also flow into the second air duct section 113 and mix with the heated first gas. The temperature of the introduced second gas can be lower than the temperature of the third gas, so that the second gas can cool the heated first gas faster to prevent the temperature of the gas blown out by the hot air device 10 from being too high, thereby avoiding overheating of the strip material 40, which is beneficial to improving the film laminating effect and film laminating quality.

[0088] In some embodiments, the first gas can enter the first air channel section 112 from the first air inlet 110, and the first gas flowing through the first air channel section 112 is heated by the heating component 13 to form a third gas. The third gas flows into the second air channel section 113, and the second gas can enter the second air channel 12 from the second air inlet 120 and flow into the second air channel section 113 from the second air outlet 121, so that the second gas and the third gas are mixed to form a fourth gas. The fourth gas flows out from the first air outlet 111. The temperature of the second gas is lower than that of the third gas.

[0089] The hot air device 10 is configured to output the third gas or the fourth gas to the film laminating head 21. The temperature of the outputted third gas or the fourth gas is greater than a preset temperature. The temperature of the fourth gas is lower than the temperature of the third gas.

[0090] Exemplarily, the preset temperature may be any value less than the expected temperature of the gas output by the hot air device 10. Exemplarily, the preset temperature may be the air temperature.
