[0031] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can also be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] The utility model embodiment discloses a heating mechanism, referring to Figure 1 , which shows a schematic diagram of the structure of the heating mechanism of an embodiment of the utility model, the heating mechanism is used to provide heat to the heating and drying device. Among them, a drying chamber 41 is provided in the heating and drying device.

[0033] Reference Figure 1 , Figure 2 and Figure 4 As shown, the heating mechanism is used to provide heat to the drying chamber 41, and the heating mechanism includes a heat source component 10, an adjustment component 20 and an air guide component 30; the heat source component 10 includes a shell 11, a heat pump and a heating element, and an installation cavity is provided in the shell 11, and the heat pump and the heating element are both arranged in the installation cavity; the adjustment component 20 is respectively connected to the heat pump and the heating element, and the adjustment component 20 is used to control at least one of the heat pump and the heating element to generate heat; the air guide component 30 is connected to the installation cavity, and the air guide component 30 is used to export the heat in the installation cavity to the drying chamber 41.

[0034] Specifically, the heat pump and the heating element are both arranged in the installation cavity of the housing 11, and the heat generated by the heat pump and the heat generated by the heating element are both located in the installation cavity.

[0035] In the embodiment of the present application, the regulating component 20 is used to control at least one of the heat pump and the heating element to generate heat. When the regulating component 20 controls the heat pump to generate heat, the air guide component 30 exports the heat generated by the heat pump in the installation cavity to the drying chamber 41. When the regulating component 20 controls the heating element to generate heat, the air guide component 30 exports the heat generated by the heating element in the installation cavity to the drying chamber 41. When the regulating component 20 controls the heat pump and the heating element to generate heat together, the air guide component 30 exports the heat generated by the heat pump and the heating element in the installation cavity to the drying chamber 41.

[0036] The working principle of the heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle net work to obtain a large amount of heat supply, and can effectively utilize the low-grade heat energy that is difficult to use to achieve energy saving. The heat pump is a highly efficient energy-saving device that fully utilizes low-grade heat energy.

[0037] In the heating mechanism of the embodiment of the present application, the regulating component 20 can control the operation of the heat source component 10 according to the temperature demand in the drying chamber 41, for example, control the heat pump and the heating element to generate heat at the same time, or control one of the heat pump and the heating element to generate heat. When the regulating component 20 controls the heat pump and the heating element to work at the same time, a higher amount of heat can be generated, and the air guide component 30 exports the higher amount of heat to the drying chamber 41, which can quickly increase the temperature in the drying chamber 41, so that the drying chamber 41 quickly enters the working state, and the heating mechanism can shorten the heating time in the drying chamber 41 to improve the drying efficiency in the drying chamber 41 and increase the production capacity in the drying chamber 41. When less heat is required in the drying chamber 41, the regulating component 20 controls one of the heat pump and the heating element to generate heat. Compared with the heat pump and the heating element generating heat at the same time, the heat pump and the heating element generating heat can save energy consumption; moreover, the heat pump is an efficient energy-saving device that utilizes low-grade thermal energy, and has low working energy consumption. Therefore, the heating mechanism of the embodiment of the present application can achieve rapid heating to avoid affecting production capacity; moreover, it also has the advantages of energy saving and high efficiency.

[0038] Optional, see Figure 1 , Figure 2 and Figure 4 As shown, the regulating component 20 includes a temperature detection unit 21 and a control unit; the temperature detection unit 21 is arranged in the drying chamber 41, and is used to detect the temperature in the drying chamber 41; the control unit is respectively connected to the temperature detection unit 21, the heat pump and the heating element, and the control unit is used to control at least one of the heat pump and the heating element to generate heat based on the temperature.

[0039] Among them, the temperature detection unit 21 is used to detect the temperature in the drying chamber 41, and the control unit is used to control at least one of the heat pump and the heating element to generate heat based on the temperature detected by the temperature detection unit 21, so as to adjust the heat generated by the heat source component 10 according to the temperature in the drying chamber 41, realize rapid adjustment of the temperature in the drying chamber 41, and achieve the purpose of energy saving.

[0040] Optionally, the rated power of the heating element is greater than the rated power of the heat pump. In this case, when a large amount of heat is needed in the drying chamber 41, the heating element and the heat pump work simultaneously, which can provide a large amount of heat to the drying chamber 41, so that the temperature in the drying chamber 41 rises rapidly. When the baked object 50 is normally baked in the drying chamber 41, when less heat is needed, the heat can be provided by the heat pump alone, and since the rated power of the heat pump is relatively small and the energy consumption is relatively low, the heat provided by the heat pump alone can save energy.

[0041] The rated power of the heating element and the rated power of the heat pump can be set according to the usage requirements, and the embodiment of the present application does not specifically limit this. For example, the total power of the heat source component 10 is 187.8KW, of which the rated power of the heat pump is 43.8KW, the rated power of the heating element is 144KW, and the temperature of the output gas of the heat source component 10 can reach up to 70°C.

[0042] Optional, see Figure 2 As shown, the drying chamber 41 is provided with a baked object 50; Figure 1 As shown, the air guide assembly 30 includes a first air guide duct 31 and a second air guide duct 32, the air inlet of the first air guide duct 31 and the air inlet of the second air guide duct 32 are respectively connected to the installation cavity, the air outlet of the first air guide duct 31 is connected to the drying chamber 41, the second air guide duct 32 extends into the drying chamber 41, and the air outlet of the second air guide duct 32 faces the baked object 50.

[0043] Specifically, the air inlet of the first air guide duct 31 is communicated with the installation cavity, and the air outlet of the first air guide duct 31 is communicated with the drying chamber 41. The heat generated by at least one of the heat pump and the heating element in the installation cavity is transmitted to the drying chamber 41 through the first air guide duct 31, so that the temperature of the drying chamber 41 increases. The air inlet of the second air guide duct 32 is communicated with the installation cavity, and the second air guide duct 32 extends into the drying chamber 41, and the air outlet of the second air guide duct 32 faces the baked object 50. The heat generated by at least one of the heat pump and the heating element in the installation cavity is directly transmitted to the baked object 50 through the second air guide duct 32, so that the baked object 50 can be directly baked.

[0044] In the heating mechanism of the embodiment of the present application, the air guide component 30 includes a first air guide duct 31 and a second air guide duct 32. While providing heat to the drying chamber 41, the air guide component 30 can directly bake the baked parts 50, accelerate the drying and curing of glue and the like in the baked parts 50, and effectively improve the drying efficiency of the baked parts 50.

[0045] Optional, see Figure 1 and Figure 2As shown, the second air guide duct 32 includes a main duct 33 and at least two sub-ducts 34, the at least two sub-ducts 34 are respectively laid in the drying chamber 41, the air inlet of the main duct 33 is communicated with the installation cavity, and the air outlet of the main duct 33 is respectively communicated with the at least two sub-ducts 34. In the above structure of the embodiment of the present application, at least two sub-ducts 34 are respectively laid in the drying chamber 41, the air outlet area of ​​the sub-ducts 34 is relatively large, and the number of baked objects 50 directly baked by the sub-ducts 34 is large, which effectively improves the drying efficiency of the baked objects 50.

[0046] Optionally, the sub-air duct 34 is provided with a sub-air duct outlet extending along the moving direction of the baked object 50. At this time, when the baked object 50 is moving, hot air is always blown toward the baked object 50 through the sub-air duct outlet, which can effectively improve the drying efficiency of the baked object 50.

[0047] Furthermore, the air outlet of the sub-air duct is a long strip structure, extending along the moving direction of the baked object 50. Figure 1 As shown, the sub-air duct 34 and the sub-air duct outlet are arranged parallel to the conveying line 42 , wherein the baked parts 50 move along the conveying line 42 .

[0048] Optionally, the air guide assembly 30 is made of metal material.

[0049] When the air guide component 30 is made of metal material, the air guide component 30 has sufficient strength. The embodiment of the present application does not specifically limit the material of the air guide component 30. The air guide component 30 is, for example, a cold-rolled carbon steel sheet.

[0050] Optionally, the drying chamber 41 is used to bake the baked object 50. According to the temperature of the baked object 50, the heat generated by the heat source assembly 10 is adjusted to match the drying temperature required by the baked object 50, which can better meet the baking temperature requirements of the baked object 50. Figure 2 and Figure 3 As shown, the temperature detection unit 21 can be arranged near the air outlet of the second air duct 32. The temperature detection unit 21 is used to detect the temperature near the baked component 50. The control unit controls at least one of the heat pump and the heating element to generate heat based on the temperature. The heating mechanism meets the baking temperature requirements of the baked component 50 while being energy-saving and efficient.

[0051] Optionally, the heating mechanism further includes a fan, which is disposed between the installation cavity and the air inlet of the air guide assembly 30 and is used to guide the heat in the installation cavity into the air guide assembly 30 .

[0052] In the embodiment of the present application, the fan can accelerate the flow of heat in the installation cavity into the air guide component 30, thereby improving the efficiency of the heat flow in the installation cavity into the air guide component 30.

[0053] Optionally, the heat pump is a variable frequency heat pump, and the regulating component 20 can make the variable frequency heat pump generate corresponding heat according to the heat generation demand, thereby avoiding energy waste. Therefore, the heating mechanism has the advantage of energy saving.

[0054] Optionally, the heating element is an electric heating tube. The electric heating tube is a tubular electric heating element, which has excellent overall performance, ultra-long life and easy maintenance. When current passes through the resistance wire of the electric heating tube, the heat generated by the resistance wire diffuses through the surface of the metal tube and then transfers to the air to achieve the purpose of heating.

[0055] Optionally, the embodiment of the present application does not specifically limit the baked component 50, for example, the baked component 50 is a battery module. The heat provided by the heating mechanism can be used to heat and bake the battery module, and during the manufacturing process of the battery module, the glue of the battery module is solidified.

[0056] The working process of the heating mechanism of the embodiment of the present application is as follows, wherein the baked component 50 is a battery module as an example for explanation, and reference is made to Figures 1 to 3 As shown:

[0057] When the temperature detection unit 21 detects that the temperature in the drying chamber 41 is lower than the first preset temperature, the drying chamber 41 needs to be heated up quickly, the regulating component 20 controls the heat pump and the heating element to generate heat at the same time, and the fan guides a large amount of heat in the installation cavity to the air guide component 30, and the air guide component 30 guides the heat to the drying chamber 41, and quickly increases the temperature in the drying chamber 41. Among them, when the temperature in the drying chamber 41 is lower than the first preset temperature, the drying chamber 41 is in the preheating stage, and the heating mechanism needs to quickly increase the temperature in the drying chamber 41.

[0058] When the temperature detection unit 21 detects that the temperature in the drying chamber 41 reaches the use requirement, the adjustment component 20 controls the heating element to stop working, and controls the heat pump to work alone to generate heat, and the fan guides the heat generated by the heat pump working alone in the installation cavity to the air guide component 30, and the air guide component 30 guides the heat to the drying chamber 41, so that the temperature in the drying chamber 41 is maintained at the use requirement. Among them, when the temperature in the drying chamber 41 reaches the use requirement, the drying chamber 41 can be used to dry the battery module.

[0059] The battery module has an optimal baking temperature. When the temperature in the drying chamber 41 reaches the use requirement and the temperature in the drying chamber 41 is higher than the optimal baking temperature, the regulating component 20 controls the heat pump to reduce the power to reduce the heat generated, thereby achieving the purpose of lowering the temperature in the drying chamber 41. When the temperature in the drying chamber 41 reaches the use requirement and the temperature in the drying chamber 41 is lower than the optimal baking temperature, the regulating component 20 controls the heat pump to increase the power to increase the heat generated, thereby achieving the purpose of raising the temperature in the drying chamber 41.

[0060] When the temperature detection unit 21 detects that the temperature in the drying chamber 41 is too high, the regulating component 20 controls the heating element and the heat pump to stop working at the same time, the fan stops working, and the heat supply to the drying chamber 41 stops.

[0061] The heating device of the heating mechanism of the embodiment of the present application uses a heat source assembly 10 as a heat source. The heat source assembly 10 includes a housing 11 and a heat pump and a heating element arranged in the housing 11. The heat provided by the heat source assembly 10 is mainly provided by the heat pump, supplemented by the heating element, and the heat pump and the heating element cooperate to adjust the heat output to the drying chamber 41. Specifically, the heat generated by the heat pump and the heating element will heat the air in the installation cavity, and the fan will guide the hot air in the installation cavity into the air guide assembly 30 to achieve baking of the battery module through the hot air.

[0062] Furthermore, the heat in the shell 11 of the heat source assembly 10 is exported to the drying chamber 41 through the air guide assembly 30. The air guide assembly 30 includes a first air guide duct 31 and a second air guide duct 32. A portion of the heat in the shell 11 is exported to the drying chamber 41 through the first air guide duct 31, and another portion of the heat in the shell 11 is directly blown to the battery module through the second air guide duct 32, thereby accelerating the curing of the glue in the battery module, improving the production rhythm, and improving the production efficiency.

[0063] The heating mechanism of the embodiment of the present application uses the heat source component 10 as the heat source. The heat source component 10 includes a heat pump and a heating element. The heating mechanism is in the preheating stage. A large amount of heat is required in the drying chamber 41. The heat pump and the heating element work at the same time, which can provide a large amount of heat energy, so that the drying chamber 41 can quickly enter the working state, and the production efficiency of the drying chamber 41 can be improved. When the temperature in the drying chamber 41 reaches the use requirement, only the heat pump works alone to generate heat, and the power of the heat pump can be adjusted intelligently by frequency conversion. The energy consumption of the heating mechanism is low, and the temperature requirements for battery module drying can be met. Moreover, the heat pump is an efficient energy-saving device that utilizes low-grade thermal energy, and has low working energy consumption. Therefore, the heating mechanism of the embodiment of the present application can achieve rapid heating, and also has the advantages of energy saving and high efficiency.

[0064] The utility model also discloses a heating and drying device, referring to Figure 4 As shown, it includes an equipment body 40, a conveyor line 42 and the above-mentioned heating mechanism. A drying chamber 41 is provided in the equipment body 40, and the conveyor line 42 is provided in the drying chamber 41 for transmitting the baked parts 50; the heating mechanism is used to provide heat to the drying chamber 41 to dry the baked parts 50.

[0065] A heating mechanism is used in the heating and drying equipment, and the heating mechanism includes a heat source component 10, an adjustment component 20 and an air guide component 30. The adjustment component 20 can control the heat generated by the heat source component 10 according to the temperature demand in the drying chamber 41. When the heating and drying equipment is in the preheating stage, the adjustment component 20 controls the heat pump and the heating element to work at the same time, which can generate a high amount of heat. The air guide component 30 exports the high amount of heat to the drying chamber 41, which can quickly increase the temperature in the drying chamber 41, so that the drying chamber 41 quickly enters the working state. The heating mechanism can shorten the heating time in the drying chamber 41 to improve the drying efficiency of the baked parts 50 located on the conveyor line 42 in the drying chamber 41, and increase the production capacity in the heating and drying equipment. When the heating and drying equipment is in normal production, the adjustment component 20 controls the heat pump to generate heat; compared with the heat pump and the heating element generating heat at the same time, the heat pump generating heat can save energy consumption; and the heat pump is an efficient energy-saving device that uses low-grade thermal energy, and has low working energy consumption. Therefore, the heating and drying equipment of the embodiment of the present application can achieve rapid heating and effectively improve production capacity; and it also has the advantages of energy saving and high efficiency.

[0066] Optional, see Figure 1 and Figure 2 As shown, the air guide assembly 30 of the heating mechanism includes a sub-air duct 34, which is arranged in the drying chamber 41. The sub-air duct 34 is provided with an air outlet facing the conveying line 42, and the air outlet of the sub-air duct 34 extends along the moving direction of the baked object 50. When the baked object 50 moves, the hot air is always blown toward the baked object 50 through the air outlet of the sub-air duct 34, which can effectively improve the drying efficiency of the baked object 50.

[0067] Optional, see Figure 1 As shown, the extension direction of the air outlet of the sub-air duct 34 and the extension direction of the sub-air duct 34 are parallel to the extension direction of the conveyor line 42, so that when the baked workpiece 50 moves along the conveyor line 42, the hot air blown out of the air outlet of the sub-air duct 34 always blows towards the baked workpiece 50, so that the baked workpiece 50 is in a baked state during the movement.
