[0032] The utility model discloses a laser heating device, which can emit lasers of different wavebands, so as to heat different materials at the same time. The target object heated by the laser heating device is heated evenly, the temperature of each part of the target object is the same, the overall temperature rise rate of the target object is fast, and the heating efficiency is high.

[0033] Please also read Figure 1 to Figure 2 , is a structural schematic diagram of a laser heating device 100 provided in an embodiment of the utility model, the laser heating device 100 includes a shell 10, a driving module 20 and a plurality of laser modules 30, the driving module 20 is arranged in the shell 10, the plurality of laser modules 30 are arranged on one side of the shell 10, and the plurality of laser modules 30 are electrically connected to the driving module 20, and the plurality of laser modules 30 are used to emit lasers of different wavelength bands.

[0034] In this embodiment, a driving module 20 is provided through a housing 10, and a plurality of laser modules 30 are provided on one side of the housing 10. The driving module 20 is electrically connected to the plurality of laser modules 30, so as to drive the plurality of laser modules 30. The plurality of laser modules 30 can emit lasers of different wavelength bands, and the driving module 20 can adjust the laser power and power density emitted by the laser module 30. In this way, when heating different materials, lasers of different wavelength bands can be emitted for different materials, and wavelength bands with higher absorption rates can be matched for different materials, so as to improve the heating efficiency. Based on this, when the laser heating device 100 is used to heat the target object, lasers of different wavelength bands are used to heat different parts of the target object, and different parts of the target object will not be heated unevenly due to different materials. On the contrary, by utilizing the characteristic that the laser heating device 100 can emit lasers of different wavelength bands, the target object heated by the laser heating device 100 is heated evenly, the temperature of each part of the target object is the same, the overall temperature rise rate of the target object is fast, and the heating efficiency is high.

[0035] For example, Figure 2As shown, the housing 10 includes a base 11, a top shell, a front end plate 13 and a rear end plate 14 which are enclosed and connected to form a second accommodating cavity (not shown), the driving module 20 is arranged in the second accommodating cavity, and a plurality of laser modules 30 are arranged on the side of the base 11 away from the second accommodating cavity. In this way, the driving module 20 is arranged by enclosing the second accommodating cavity, and the driving module 20 can be protected by the base 11, the top shell, the front end plate 13 and the rear end plate 14. In addition, the driving module 20 can be exposed by detaching the top shell, the front end plate 13 and / or the rear end plate 14, so that the driving module 20 can be inspected or replaced, and the operation difficulty is relatively low.

[0036] For example, when a component suspected to be located at the front end of the driving module 20 fails, the front end plate 13 can be detached for inspection. When a component suspected to be located at the rear end of the driving module 20 fails, the rear end plate 14 can be detached for inspection, and so on. Exposing only the faulty part can reduce the difficulty of inspection.

[0037] In some embodiments, such as Figure 3 As shown, each laser module 30 includes a flexible circuit board 31, a plurality of light-emitting elements 32 and a light-transmitting member 33. The flexible circuit board 31 is arranged on one side of the housing 10 and is electrically connected to the driving module 20. The plurality of light-emitting elements 32 are arranged in an array on the flexible circuit board 31, and the light-transmitting member 33 is arranged on the light-emitting side of the plurality of light-emitting elements 32. In this way, the driving module 20 can drive the plurality of light-emitting elements 32 arranged on the flexible circuit board 31 to emit light through the electrical connection between the flexible circuit board 31 and the driving module 20, and the light is emitted through the light-transmitting member 33, which can avoid the situation of blocking the light. At the same time, a light-transmitting member 33 is used to separate the plurality of light-emitting elements 32 and provide a light-transmitting area, thereby reducing the number of components and extending the service life of the laser heating device 100.

[0038] Exemplarily, each laser module 30 further includes a light guide 34, which is disposed between the light emitting element 32 and the light-transmitting element 33, and is used to perform homogenization on the light emitted by the light emitting element 32. In this way, by integrating a plurality of light emitting elements 32 on the flexible circuit board 31, the light emitted by the light emitting element 32 is homogenized by the light guide 34 to form a light spot with uniform intensity, so that the laser emitted by the laser module 30 has a better heating effect, a higher heating efficiency, and can shorten the heating time.

[0039] In addition, the output power of the light emitting elements 32 in different areas among the multiple light emitting elements 32 can be controlled by adjusting the current through the driving module 20, so that the power curve of the light spot output by the laser module 30 can be controlled, so that when the multiple laser modules 30 emit lasers to heat the target object, all parts of the target object can be heated evenly.

[0040] For example, when the laser heating device 100 is used to heat and cure the packaging glue of the perovskite cell panel, the use of multiple array-arranged light-emitting elements 32 can meet the larger area size of the perovskite cell panel, and the light emitted by the light-emitting element 32 is uniformly treated to form a light spot with uniform intensity, which quickly cures the packaging glue with a short curing time and high efficiency.

[0041] Exemplarily, the light guide 34 includes a light homogenizing channel 34a, a first open end 34b, and a second open end 34c, wherein the first open end 34b is connected to the light homogenizing channel 34a, the first open end 34b is arranged toward the light emitting side of the light emitting element 32, the second open end 34c is connected to the light homogenizing channel 34a, and the light-transmitting element 33 is arranged at the second open end 34c. In this way, through the first open end 34b toward the light emitting element 32, the light emitted by the light emitting element 32 can enter the light homogenizing channel 34a through the first open end 34b, and be emitted from the light-transmitting element 33 at the second open end 34c, thereby achieving light homogenization processing of the light.

[0042] Optionally, the shape of the light guide 34 is configured as a trapezoid, a cube, or a cylinder. In this way, the present embodiment provides a plurality of light guides 34 of different shapes, which can be selected according to actual conditions, and the present embodiment does not specifically limit this. In some other embodiments, the light guide 34 can also be other shapes, not limited to the shapes listed in the present embodiment.

[0043] In some embodiments, such as Figure 1 and Figure 4 As shown, the housing 10 is provided with a water inlet 10a and a plurality of water outlets 10b, and each laser module 30 includes a heat exchanger 35, and the heat exchanger 35 has a first accommodating chamber (not shown), the first accommodating chamber is connected to the water inlet 10a and the water outlet 10b, and the plurality of first accommodating chambers correspond to the plurality of water outlets 10b one by one. In this way, the first accommodating chamber of the heat exchanger 35 is connected to the water inlet 10a and the water outlet 10b, and the water inlet 10a can pass the coolant into the first accommodating chamber and discharge it from the water outlet 10b, so that the coolant can exchange heat with the laser module 30, remove the heat generated by the laser module 30, realize the heat dissipation of the laser module 30, and avoid the occurrence of heat accumulation affecting the normal operation of the laser module 30. In addition, the coolant passed through the water inlet 10a can flow to the plurality of first accommodating chambers, and be discharged from the plurality of first accommodating chambers to the plurality of corresponding water outlets 10b, which can simplify the pipeline of the coolant and has a relatively simple structure.

[0044] Specifically, the heat exchanger is disposed on a side of the flexible circuit board 31 away from the light emitting element 32 .

[0045] Exemplarily, the heat exchanger 35 is provided with a water inlet 35a and a water outlet 35b connected to the first accommodating chamber, the water inlet 35a is connected to the water inlet 10a, the water outlet 35b is connected to the water outlet 10b, and the multiple water outlets 35b correspond to the multiple water outlets 10b one by one. In this way, the coolant introduced into the water inlet 10a can enter the first accommodating chamber from the water inlet 35a through the water inlet 35a, and after heat exchange, the coolant can flow from the water outlet 35b to the corresponding water outlet 10b, thereby being discharged from the first accommodating chamber. In addition, the multiple water outlets 35b discharge the coolant through the multiple water outlets 10b respectively, which can improve the drainage efficiency, thereby improving the heat exchange efficiency of the heat exchanger 35, and the heat dissipation effect is better.

[0046] In some embodiments, such as Figure 4 and Figure 5 As shown, the laser heating device 100 also includes a blowing module 40, which is arranged on one side of the housing 10. The blowing module 40 is used to blow air toward the target object irradiated by the laser emitted by the laser module 30. In this way, by blowing air toward the target object through the blowing module 40, impurities such as dust on the surface of the target object can be removed, and the surface of the target object can be kept smooth. When the laser emitted by the laser module 30 irradiates the surface of the target object, the absorption effect of the laser by the target object can be improved, thereby improving the heating efficiency. In addition, when the target object is heated and heated, it usually emits water vapor or other evaporation, which is easy to adhere to the light emitting position (such as the light-transmitting member 33, the light-emitting element 32) of the laser module 30 as the hot air flow rises. The blowing module 40 of this embodiment can blow the water vapor or other evaporation emitted by the target object away from the light emitting position of the laser module 30 to avoid attachment to the light emitting position to cause pollution and affect the normal light emitting of the laser module 30.

[0047] Exemplarily, the blowing module 40 includes an air supply port 40a and an air outlet member 41, wherein the air outlet member 41 is provided with an air inlet 41a and a plurality of air outlets 41b, wherein the air inlet 41a is connected to the air supply port 40a for receiving the gas provided by the air supply port 40a, and the plurality of air outlets 41b are connected to the air inlet 41a for discharging the gas received by the air inlet 41a. In this way, the gas is introduced through the air supply port 40a, the gas can enter the air outlet member 41 through the air inlet 41a, and be discharged through the plurality of air outlets 41b, and the gas discharged has a wide distribution range, and can be blown to the entire surface of the target object.

[0048] Optionally, the gas outlet direction of the gas outlet 41b is arranged to intersect with the laser emission direction of the laser module 30. In this way, by intersecting the gas outlet direction of the gas outlet 41b with the laser emission direction of the laser module 30, the gas discharged from the gas outlet 41b can pass through the optical path of the laser emitted by the laser module 30, thereby removing impurities such as dust floating on the optical path, and avoiding the laser being scattered and refracted due to interference from impurities, resulting in the laser being unable to efficiently irradiate the target object.

[0049] In some embodiments, the junction and Figure 1 As shown, the plurality of laser modules 30 include a first laser module 30a and a second laser module 30b, and the first laser module 30a and the second laser module 30b are arranged at intervals. The air blowing module 40 also includes a first baffle 42 and a second baffle 43, and the first baffle 42 and the second baffle 43 are respectively arranged at the two ends of the air outlet 41, and are located between the first laser module 30a and the second laser module 30b, and are enclosed with the housing 10, the first laser module 30a, the second laser module 30b and the air outlet 41 to form a cavity, and an air pipe (not shown) is arranged in the cavity, and the two ends of the air pipe are respectively connected to the air inlet 41a and the air supply port 40a, and the air supply port is arranged at the first baffle or the second baffle, and the air supply port 40a is arranged at the first baffle 42 or the second baffle 43. In this way, by arranging the first laser module 30a and the second laser module 30b at intervals, the first laser module 30a and the second laser module 30b emit lasers of different wavelengths, and different positions of the target object can be heated. In addition, the first baffle 42 and the second baffle 43 are used to cooperate with the shell 10, the first laser module 30a, the second laser module 30b and the air outlet piece 41 to form a cavity, and an air pipe is arranged in the cavity to connect the air supply port 40a and the air inlet 41a. The gas introduced into the air supply port 40a can pass from the air inlet 41a to the air outlet piece 41 through the air pipe.
