Description

Technical Field

[0001] This application relates to the field of manufacturing, and specifically to drying equipment and a drying method for drying equipment.

Background Art

[0002] When performing a drying process on an object to be dried with conventional drying equipment, if the drying effect is poor, it will affect the yield rate of the product.

[0003] Taking a solar cell as an example, a solar cell is generally manufactured on glass coated with a transparent conductive film, where most of the organic layers are generally formed by a coating method. The organic sol to be coated is generally a liquid compounding solution, and after the coating is completed, it is necessary to volatilize the excess organic solution by drying to form an organic film layer. After drying the organic sol with conventional drying equipment, the drying effect is poor and the formed organic film layer becomes uneven. Therefore, the prior art should be improved urgently.

Summary of the Invention

[0004] In view of the above problems, this application provides a drying equipment and a drying method for drying equipment that can solve the problems of conventional drying equipment, such as poor drying effect and uneven film layer formed after drying.

[0005] According to a first aspect, the present application provides a drying apparatus comprising a cavity having a housing cavity, the housing cavity having a drying waiting area, a heat source installed in the housing cavity, the heating area of ​​the heat source covering the drying waiting area, a morphology detection device installed in the housing cavity, the collection area of ​​the morphology detection device covering the drying waiting area, and a control unit connected to the heat source and the morphology detection device. Specifically, with the above installation, the control unit can control the operating state of the heat source (position, power, on or off, etc.) based on the morphology of the film surface of the object to be dried in the drying waiting area detected by the morphology detection device, which is advantageous in improving the uniformity of drying for the object to be dried.

[0006] In some embodiments, the number of heat sources is multiple, and the heating regions of the multiple heat sources cover different areas of the drying waiting area. By installing multiple heat sources and covering different areas of the drying waiting area, it is possible to dry the area in sections, and it is advantageous to further improve the uniformity of drying for the items to be dried.

[0007] In some embodiments, the drying apparatus further includes a temperature detection device installed in the containment cavity, and the temperature detection device is communicated to the control unit. By installing the temperature detection device in the containment cavity, the control unit can adjust the drying rate by adjusting the radiant intensity of the heat source based on the detected temperature, which is advantageous for achieving uniform drying of the object to be dried.

[0008] In some embodiments, the number of temperature detection devices is multiple, and each of the multiple temperature detection devices is communicated to the control unit. By installing multiple temperature detection devices, the multiple temperature detection devices may be arranged in separate areas, which is advantageous in improving detection accuracy and achieving uniform drying of the object awaiting drying.

[0009] In some embodiments, the number of heat sources is multiple, and at least one temperature detection device is installed in conjunction with each heat source. By installing at least one temperature detection device in conjunction with each heat source, accurate temperature measurement can be achieved, and it is also advantageous for achieving uniform drying of the object awaiting drying.

[0010] In some embodiments, the heat source is fixedly installed within the housing cavity, or it is slidably installed within the housing cavity. Specifically, different connection relationships between the heat source and the housing cavity are advantageous in selecting the appropriate type according to actual needs, thereby reducing equipment costs or improving equipment performance.

[0011] In some embodiments, the heat sources are fixedly installed within the containment cavity, and there are multiple heat sources. Here, the multiple heat sources are uniformly distributed at the top of the containment cavity, or the multiple heat sources form multiple heat source areas with different distribution densities at the top of the containment cavity. Designing the arrangement of multiple heat sources according to actual needs and achieving uniform drying of the items awaiting drying is advantageous in reducing equipment costs.

[0012] In some embodiments, the morphological detection device includes a morphological collection assembly, which is slidably connected to the cavity, or fixedly connected to the cavity. Specifically, different connection relationships between the morphological collection assembly and the cavity are advantageous in making appropriate type selections as required by practical needs, thereby simplifying the device structure or improving device performance.

[0013] In some embodiments, the morphology detection device includes a plurality of morphology collection assemblies, which are arranged in an array within the housing cavity. Arranging the plurality of morphology collection assemblies in an array is advantageous for collecting the morphology of the film surface awaiting drying by the morphology collection assemblies.

[0014] In some embodiments, multiple morphology collection assemblies are installed in a one-to-one correspondence with multiple temperature detection devices, and one morphology collection assembly is integrated with one temperature detection device. By integrating the morphology collection assemblies and temperature detection devices in a one-to-one correspondence, the degree of integration of the equipment can be improved, making the assembly of the equipment easier and contributing to a reduction in equipment costs.

[0015] In some embodiments, the heat source includes one or more of the following: an infrared heat source, an incandescent lamp, a tungsten halogen lamp, a hot plate, and a microwave generator. Based on the selection of different types of heat sources, it is advantageous to select the appropriate heat source according to the actual needs, thereby reducing equipment costs or improving equipment performance and thus enhancing market competitiveness.

[0016] In some embodiments, the temperature detection device includes one or more types of thermocouple temperature sensors and thermal resistance temperature sensors. This facilitates the selection of the type of temperature detection device.

[0017] In some embodiments, the cavity further includes an airflow passage that connects the cavity to the outside. By providing an airflow passage, the passage may be used to connect external equipment, and the external equipment may further realize the corresponding cavity environment. For example, the inside of the cavity may be evacuated, which is advantageous for drying items awaiting drying.

[0018] In some embodiments, the configuration further includes a mounting device installed in the drying waiting area. Here, the heat source and the mounting device are spaced apart, the mounting device is located at the bottom of the housing cavity, the heat source is located at the top of the housing cavity, and the morph detection device is located between the mounting device and the heat source. Specifically, the mounting device is used to mount the object to be dried, and the relative positions of the heat source, mounting device, and morph detection device are arranged to optimize the arrangement of each assembly within the housing cavity so that each assembly does not interfere with one another when operating.

[0019] According to a second aspect, the present application provides a drying method for a drying apparatus used in any one of the above-described drying apparatuses, the drying method comprising acquiring the surface morphology of a film awaiting drying detected by a morphology detection device, and controlling the operating state of a heat source based on the surface morphology of the film awaiting drying. Specifically, this drying method can control the operating state of a heat source based on the surface morphology of a film awaiting drying in a drying area detected by a morphology detection device, which is advantageous in improving the uniformity of drying for the film awaiting drying.

[0020] In some embodiments, controlling the operating state of the heat source based on the film surface morphology includes obtaining film surface differentiation information by comparing it with a stored, uniformly dried standard film surface morphology based on the film surface morphology, and adjusting the operating state of the heat source based on the film surface differentiation information. Specifically, obtaining film surface differentiation information by comparing it with a pre-stored standard film surface morphology is advantageous for targeting the heat source to dry the object awaiting drying, thereby improving the uniformity of drying.

[0021] In some embodiments, adjusting the operating state of the heat source based on the film surface differentiation information includes adjusting the radiant intensity of the heat source corresponding to different regions of the object awaiting drying based on the film surface differentiation information. Specifically, by precisely adjusting the radiant intensity of the heat source corresponding to different regions of the object awaiting drying based on the film surface differentiation information, it is advantageous to dry different regions of the object awaiting drying in a targeted manner and to improve the uniformity of drying for the object awaiting drying.

[0022] In some embodiments, the number of heat sources is multiple, and controlling the operating state of the heat sources based on the film surface morphology includes controlling the heat sources in the region corresponding to the object awaiting drying to heat the object awaiting drying, and controlling the heat sources in regions other than those corresponding to the object awaiting drying to stop operating. In this way, not only can uniform drying be achieved for the object awaiting drying, but costs can also be reduced by stopping the operation of the heat sources in regions other than those corresponding to the object awaiting drying.

[0023] In some embodiments, acquiring the surface morphology of the object awaiting drying detected by the morphology detection device includes acquiring an image and / or contour of the object awaiting drying detected by the morphology detection device. Specifically, by detecting an image and / or contour of the object awaiting drying, the control unit can determine the shape boundaries and / or degree of drying of the object awaiting drying, thereby enabling targeted control of the operating state of multiple heat sources, which helps to dry the object awaiting drying uniformly.

[0024] In some embodiments, the method further includes controlling the heat source to move within the containment cavity based on the film surface morphology. Specifically, this method controls the heat source to move within the containment cavity based on the film surface morphology and adjusts the positions of multiple heat sources based on the film surface morphology of the object awaiting drying to achieve an optimal heat source arrangement, which is advantageous for achieving uniform drying of the object awaiting drying.

[0034] Solar cells are a type of device that uses the photoelectric conversion principle to convert solar radiation into electrical energy using semiconductor materials. This photoelectric conversion process is generally called the "photoelectron emission effect," and therefore solar cells are also called "photovoltaic batteries." Currently, given the development of the market, the applications of solar cells are expanding more and more. They are not only used in power systems for energy storage, but are also widely applied in electric vehicles and other electric transportation tools, as well as in many fields such as military equipment and aerospace. With the continuous expansion of solar cell applications, the market demand is also constantly increasing.

[0035] Here, the manufacturing of solar cells generally involves the step of applying an organic sol-based solution to glass plated with a transparent conductive film to form an organic film layer. The organic film layer formed with the organic sol-based solution needs to be dried to volatilize any excess organic solution, and the drying and volatilization process requires that the formed organic film layer be very uniform.

[0036] However, the inventors of this application have found the following:

[0037] 1. Due to the large scale of industrial solar cells, most conventional drying equipment employs an airflow field for drying, making it difficult to achieve uniform drying.

[0038] 2. Considering the application to the specifications of various solar cell products, when the battery size changes, it is difficult to meet the conditions for uniform drying in a single heat field.

[0039] Conventional drying equipment typically includes a device capable of generating radiant heat and / or an airflow device, achieving drying of the object to be dried through radiant heat and airflow. This equipment is widely applied in manufacturing fields such as display panel manufacturing and solar cell manufacturing.

[0040] To address the problem of uneven drying of materials awaiting drying using conventional drying equipment, the applicant conducted research and discovered the following: It is possible to control the heat field in different regions within the drying equipment and obtain the surface morphology of the material awaiting drying. Based on the surface morphology of the material awaiting drying, the drying of the material with the corresponding heat field can be controlled, thereby achieving the objective of uniform drying.

[0041] Based on the above considerations, in order to solve the problem of uneven drying of items awaiting drying using conventional drying equipment, the inventor conducted diligent research and proposed the following technical solution.

[0042] Referring to Figures 1 to 7, Figure 1 is a schematic diagram of the structure of one embodiment of the drying apparatus according to the present application, Figure 2 is a schematic diagram of the structure of another embodiment of the drying apparatus according to the present application, Figure 3 is a plan view of one embodiment of the interior cavity of the drying apparatus according to the present application, Figure 4 is a plan view of another embodiment of the interior cavity of the drying apparatus according to the present application, Figure 5 is a plan view of another embodiment of the interior cavity of the drying apparatus according to the present application, Figure 6 is a plan view of another embodiment of the interior cavity of the drying apparatus according to the present application, and Figure 7 is a plan view of another embodiment of the interior cavity of the drying apparatus according to the present application.

[0043] This application describes the design of a drying apparatus 100, which includes a cavity 10, a heat source 30, a morphology detection device 40, and a control unit 50. Here, the cavity 10 has a housing cavity 101, which has a drying waiting area, the heat source 30 is installed in the housing cavity 101, the heating area of ​​the heat source 30 covers the drying waiting area and is used to dissipate heat under operating conditions to dry the drying waiting objects 200 located in the drying waiting area. The morphology detection device 40 is installed in the housing cavity 101, the collection area of ​​the morphology detection device 40 covers the drying waiting area and is used to detect the film surface morphology of the drying waiting objects 200 located in the drying waiting area. The control unit 50 is connected to the heat source 30 and the shape detection device 40, respectively. Based on the film surface morphology of the object 200 awaiting drying detected by the shape detection device 40, the control unit 50 controls the operating state of the heat source 30 to form a targeted heat field, thereby achieving uniform drying of the object 200 awaiting drying.

[0044] Here, cavity 10 refers to the casing of the equipment in which a housing space is formed. In this application, a housing cavity 101 is formed in cavity 10, and the housing cavity 101 is used to house a heat source 30, a shape detection device 40, and an object 200 awaiting drying. The shape and size of cavity 10 are not limited and may be designed as needed. In this application, cavity 10 is a metal casing.

[0045] Here, the heat source 30 refers to an element capable of releasing thermal energy under operating conditions, such as a thermal radiating light fixture, an infrared light source, and a microwave generator. The number of heat sources 30 may be multiple, and the multiple heat sources 30 may be multiple heat sources 30 installed independently and spaced apart or without spacing. The multiple heat sources 30 may be a single heat source device including multiple independently controllable heat dissipation regions, and the multiple heat dissipation regions characterize the multiple heat sources 30. Alternatively, the number of heat sources 30 may be one, and the one heat source 30 is slidably connected to the cavity 10, thereby the one heat source 30 is movably installed in the housing cavity 101.

[0046] Here, the drying waiting area is the region covered by the thermal energy released by the heat source 30 under operating conditions, and the drying waiting area is used to accommodate the items 200 awaiting drying and to dry the items 200 when the heat source 30 is operating.

[0047] Here, the object awaiting drying 200 is a substance to be dried, such as a film layer awaiting curing, a liquid, a semi-solid, or a solid substance containing a certain amount of liquid. The object awaiting drying 200 includes, but is not limited to, the organic sol-containing solution of this application. Here, when the object awaiting drying 200 is located in the drying area, it needs to have a certain degree of support, for example, the object awaiting drying 200 may be placed on a substrate (such as a glass substrate), and the substrate may be placed in the drying area. In this application, the object awaiting drying 200 is a transparent conductive glass coated with an organic sol-containing solution.

[0048] Here, the morphology detection device 40 refers to a device that acquires the surface morphology of the object 200 awaiting drying using methods such as scanning or photography. Specifically, the morphology detection device 40 detects the surface morphology of the object 200 awaiting drying, and the control unit 50 obtains the shape and / or degree of drying of the object 200 awaiting drying. Furthermore, based on this surface morphology, the operating state of the heat source 30 can be precisely controlled, which helps to uniformly dry the object 200 awaiting drying.

[0049] Here, the control unit 50 generally includes a processor and memory, and the processor may be called a CPU (Central Processing Unit). The processor may be an integrated circuit chip having signal processing capabilities. The processor may further be a general-purpose processor, a digital signal processor (DSP), an application-designed integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware assembly. The general-purpose processor may be a microprocessor, or this processor may be any general-purpose processor, etc. The memory may be a memory strip, a TF card, etc., and can store all information in the device, and the input raw data, computer programs, intermediate operation results and final operation results are all stored in the memory. It retrieves and retrieves information based on a location specified by the processor. Only when memory is present can the control unit 50 have a storage function and guarantee normal operation. In this application, the control unit 50 may be installed on the outer surface of the cavity 10, installed outside the cavity 10 and spaced apart from the cavity 10, but is not limited thereto.

[0050] Specifically, when drying an object 200 awaiting drying in the drying equipment 100, it is first necessary to transport the object 200 awaiting drying to the drying waiting area in the housing cavity 101 using a mechanical arm or conveyor belt, and then to seal the housing cavity 101. The morphology detection device 40 detects the film surface morphology of the object 200 awaiting drying, and the control unit 50 controls the operating state of one or more heat sources 30 based on the film surface morphology detected by the morphology detection device 40. Alternatively, the control unit 50 obtains film surface differentiation information by comparing it with a stored, uniformly dried standard film surface morphology based on the film surface morphology detected by the morphology detection device 40, and further controls the operating state of one or more heat sources 30 based on the film surface differentiation information. Here, the control unit 50 controlling the operating state of one heat source 30 includes controlling the heat source 30 to move within the housing cavity 101 to a target position, adjusting the operating power of the one heat source 30, and thereby drying the object 200 awaiting drying. The control unit 50 controls the operating state of the multiple heat sources 30, which includes turning some of the heat sources 30 on and off and adjusting the radiant intensity of the multiple heat sources 30, and after the drying process is completed for a certain period of time, a uniformly dried film surface is obtained, and finally the uniformly dried drying object 200 is removed from the housing cavity 101 and prepared for use.Here, the control unit 50 controls the operating state of the multiple heat sources 30, which includes turning some of the heat sources 30 on and off and adjusting the operating power of the multiple heat sources 30, and by forming corresponding hot field regions within the housing cavity 101, the drying object 200 is dried, after the drying process is completed for a certain period of time, a uniformly dried film surface is obtained, and finally the uniformly dried drying object 200 is removed from the housing cavity 101 and prepared for use.

[0051] To make it easier to understand, this application uses a morphology detection device 40 to detect the film surface morphology of the object awaiting drying 200, and a control unit 50 controls the operating state of the heat source 30 based on the film surface information detected by the morphology detection device 40, thereby forming a targeted heat field based on the film surface morphology of the object awaiting drying 200 and achieving uniform drying of the object awaiting drying 200. Therefore, when faced with the problem of uneven drying of large-sized and / or different specification sizes of solar cells, the drying equipment 100 according to this application can detect the film surface morphology in real time using the morphology detection device 40, compare it with a standard and uniform dried film surface morphology, and, for differentiated morphologies, control the operating state of the heat source 30 using the control unit 50, for example, by adjusting the operating power of the heat source 30 in the corresponding area, thereby achieving uniform drying of the entire film surface. The object awaiting drying 200 in this application is a two-dimensional film with a small thickness, so the uniformity of drying of the object awaiting drying 200 is mainly in the film direction parallel to the object awaiting drying 200, i.e., the horizontal direction. Therefore, this application divides the housing cavity 101 into multiple drying regions along the horizontal direction, with one or more heat sources 30 installed corresponding to each drying region, or a single movable heat source 30 dries different drying regions.

[0052] In some embodiments, the number of heat sources 30 is selectively multiple, and the control unit 50 controls the heat sources 30 in the region corresponding to the drying target 200 to heat the drying target 200, and controls the heat sources 30 in the region other than the drying target 200 to stop operating.

[0053] Here, the amount of heat released by each heat source 30 during operation covers a certain area of ​​the object awaiting drying 200, and this area is the corresponding area between the heat source 30 and the object awaiting drying 200. The heat source 30 in the area corresponding to the object awaiting drying 200 refers to all heat sources 30 whose amount of heat released during operation covers the object awaiting drying 200.

[0054] Specifically, the initial state of the multiple heat sources 30 may be all on, all off, or some on and some off. When the object to be dried 200 is placed on the placement device 20, the morphology detection device 40 detects the film surface morphology of the object to be dried 200. The control unit 50 obtains the contour of the object to be dried 200 based on the film surface morphology detected by the morphology detection device 40, and dries the object to be dried 200 by controlling the heat sources 30 in the region corresponding to the object to be dried 200 to heat it. Furthermore, the heat sources 30 other than the region corresponding to the object to be dried 200 are controlled to stop operating, that is, the heat sources 30 other than the region corresponding to the object to be dried 200 are controlled to stop operating. In this way, it is possible to not only achieve uniform drying of the object to be dried 200 in a targeted manner, but also to reduce drying costs.

[0055] Here, the initial state of the multiple heat sources 30 may all be on, that is, when the item to be dried 200 is not located in the drying waiting area, or when it has just arrived in the drying waiting area, all of the multiple heat sources 30 are in operation. This allows the drying process to start immediately after the item to be dried 200 enters the storage cavity 101, thereby increasing drying efficiency.

[0056] Here, the initial state of all the heat sources 30 may be off; that is, when the item to be dried 200 is not located in the drying area, or when it has just arrived in the drying area, none of the heat sources 30 operate. This way, costs can be saved and energy waste can be reduced.

[0057] Here, the initial state of the multiple heat sources 30 may be partially on and partially off. For example, the initial state of the multiple heat sources 30 is the last state at the end of the previous drying cycle. Alternatively, based on the shape of the object 200 awaiting drying, some of the heat sources 30 may be turned on or off in advance, and the control unit 50 may adjust by turning on or off some of the heat sources 30 after obtaining the film surface shape of the object 200 awaiting drying. This increases drying efficiency and saves costs.

[0058] Here, when there is only one heat source 30, if this heat source 30 is located outside the area corresponding to the drying object 200, the control unit 50 controls this heat source 30 to move from outside the area corresponding to the drying object 200 to the area corresponding to the drying object 200, and also turns on this heat source 30 to dry the drying object 200 uniformly. If this heat source 30 is located in the area corresponding to the drying object 200, the control unit 50 controls this heat source 30 to turn on in order to dry the drying object 200 uniformly.

[0059] To simplify the explanation, the following describes the case where there are multiple heat sources 30.

[0060] In some embodiments, the control unit 50 selectively adjusts the radiant intensity of the heat source 30 in the region corresponding to the object awaiting drying 200 to dry the object awaiting drying.

[0061] Specifically, there is a positive correlation between the radiant intensity of the heat source 30 and the operating power of the heat source 30. That is, the greater the operating power of the heat source 30, the greater the radiant intensity and the higher the temperature generated by the released thermal energy. Conversely, the smaller the operating power of the heat source 30, the smaller the radiant intensity and the lower the temperature generated by the released thermal energy.

[0062] In this application, the control unit 50 adjusts the radiation intensity of the heat source 30 in the region corresponding to the object awaiting drying 200 based on the film surface morphology detected by the morphology detection device 40 or the film surface differentiation information obtained by comparison, thereby targeting the drying of the object awaiting drying 200 and further improving the uniformity of drying for the object awaiting drying 200.

[0063] To make it clear, when drying the object awaiting drying 200, the drying conditions (e.g., temperature) at different stages may differ, or there may be differences in the degree of drying of different areas of the same object awaiting drying 200. Therefore, the control unit 50 adjusts the radiant intensity of the heat source 30 in the area corresponding to the object awaiting drying 200, based on the film surface morphology detected by the morphology detection device 40, or the film surface differentiation information obtained by comparison, to form a targeted heat field and change the drying temperature for the object awaiting drying at different stages. Alternatively, different drying temperatures may be provided to different areas of the same object awaiting drying 200. This improves the uniformity of drying for the object awaiting drying 200.

[0064] In some embodiments, the film surface morphology selectively includes an image and / or contour of the object awaiting drying.

[0065] Here, the image refers to the surface morphology of the object 200 awaiting drying, and may be a two-dimensional or three-dimensional image. For example, the image can reflect the degree of drying, in-plane texture, in-plane wrinkles, in-plane unevenness, etc. of the object 200 awaiting drying.

[0066] Here, the contour is the boundary or outline that constitutes any single shape.

[0067] In this application, by detecting the shape and / or contour of the object 200 awaiting drying using the shape detection device 40, the control unit 50 can precisely control the operating state of multiple heat sources 30 by determining the shape boundary and / or degree of drying of the object awaiting drying. For example, the control unit 50 can save drying costs by controlling multiple heat sources 30 within the shape boundary of the object 200 awaiting drying based on the contour of the object 200 to activate, and controlling multiple heat sources 30 outside the shape boundary of the object 200 awaiting drying to not activate. Alternatively, the control unit 50 can adjust the radiant intensity of the heat sources 30 corresponding to different drying regions of the object 200 awaiting drying based on the shape of the object 200 awaiting drying, thereby forming a targeted heat field for regions with different degrees of drying, which helps to dry the object 200 awaiting drying uniformly.

[0068] In some embodiments, selectively referring to Figure 2, the drying apparatus 100 further includes a mounting device 20 installed in the drying waiting area, where the heat source 30 and the mounting device 20 are spaced apart, the mounting device 20 is located at the bottom of the housing cavity 101, the heat source 30 is located at the top of the housing cavity 101, and the morphological detection device 40 is located between the mounting device 20 and the heat source 30.

[0069] Here, the mounting device 20 is used to provide a stable mounting surface for the object 200 awaiting drying. Specifically, the mounting device 20 may be an object having a mounting surface, or it may be composed of multiple mounting columns forming the mounting surface, as long as the object 200 awaiting drying can be stably mounted on the mounting device 20.

[0070] Specifically, the mounting device 20 is used to place the object to be dried 200 on it and to position the object to be dried 200 in the drying area when drying is performed. Multiple heat sources 30 are installed on the surface of the mounting device 20 for placing the object to be dried 200, and may be in contact with the object to be dried 200, or installed inside the mounting device 20, in order to increase the drying rate. The material of the mounting device 20 may be a material with excellent thermal conductivity, and the heat sources 30 indirectly transfer heat to the object to be dried 200 by heating the mounting device 20. In the above installation method, the amount of heat released by the heat sources 30 has a high rate of heat transfer to the object to be dried 200, thereby increasing the drying efficiency, and the multiple heat sources 30 can be installed inside the mounting device 20 or on the surface of the mounting device 20, improving the degree of integration of the device, and it is possible to avoid affecting the mounting space of other components (e.g., morphology detection device 40).

[0071] Here, being installed with a gap means that there is a certain distance between the heat source 30 and the mounting device 20 without them coming into contact. Here, the structure of the mounting device 20 is not limited and may include a stage or bracket, the stage or bracket having a mounting surface. Specifically, the heat source 30 and the mounting device 20 are installed with a gap between them to facilitate the independent installation or replacement of the heat source 30 or the mounting device 20.

[0072] Here, the top and bottom of the containment cavity 101 are two opposing regions within the containment cavity 101, with the bottom being the region of the interior space closer to the ground and the top being the region of the interior space further away from the ground. By installing the mounting device 20 at the bottom of the containment cavity 101, the mounting of the drying object 200 can be easily done. By installing the heat source 30 at the top of the containment cavity 101 and positioning it opposite the mounting device 20 at a distance, the heat source 30 does not affect the drying of the drying object 200 placed on the mounting device 20. The morphology detection device 40 is installed between the mounting device 20 and the heat source 30, and when the morphology detection device 40 detects the film surface morphology of the drying object 200 placed on the mounting device 20 below it, the heat source 30 does not affect the detection. For example, when the morphology detection device 40 employs a slide scanning detection method, the heat source 30 and the mounting device 20 do not obstruct the sliding path when the morphology detection device 40 slides. Furthermore, when the heat source 30 dries the object 200 awaiting drying, the morphology detection device 40 can slide closer to the side wall of the housing cavity 101, and the morphology detection device 40 does not obstruct the heat source 30.

[0073] Specifically, by optimizing the arrangement of the heat source 30, the shape detection device 40, and the mounting device 20 within the housing cavity 101, each assembly does not interfere with one another when in operation.

[0074] In some embodiments, the number of heat sources 30 is selectively multiple, and the heating regions of the multiple heat sources 30 cover different areas of the drying waiting area.

[0075] Specifically, by installing multiple heat sources 30, and having the multiple heat sources 30 cover different areas of the drying waiting area, it is possible to dry the area separately, which is advantageous in improving the uniformity of drying for the object awaiting drying. For example, if different areas of the same object awaiting drying 200 have different degrees of drying, the control unit 50 adjusts the radiant intensity of the heat sources 30 corresponding to the different areas of the film surface of the object awaiting drying 200, thereby creating a targeted heat field and improving the uniformity of drying.

[0076] In some embodiments, selectively referring to Figure 1, the drying apparatus 100 further includes a temperature detection device 60 installed in the containment cavity 101, and the temperature detection device 60 is further connected to a control unit 50.

[0077] Here, the temperature detection device 60 refers to a device for detecting the temperature of the environment awaiting detection or the object awaiting detection. In this application, the temperature detection device 60 is used to detect the temperature inside the containment cavity 101 and / or the film surface temperature of the object awaiting drying 200, and to output the detection result to the control unit 50 by wired transmission or wireless communication.

[0078] In this application, a temperature detection device 60 is installed in a housing cavity 101, and the temperature detection device 60 may be installed in the housing cavity 101 via a bracket or suspension rod. For example, a lifting rod is attached to the top wall of the housing cavity 101, and the temperature detection device 60 is fixed to the bottom end of the lifting rod, and the lifting rod can position the temperature detection device 60 in areas of different heights. As can be understood, the closer the temperature detection device 60 is to the object to be dried 200, the closer the detected temperature is to the film surface temperature of the object to be dried 200. Here, the temperature detection device 60 is used to sense the temperature in its area and convert it into a usable output signal which is provided to the control unit 50. The control unit 50 then adjusts the radiant intensity of the corresponding heat source 30 based on the temperature of the area detected by the temperature detection device 60 to bring the temperature in the area within a preset temperature range, thereby achieving uniform drying.

[0079] In some embodiments, the number of temperature detection devices 60 is selectively multiple, and each of the multiple temperature detection devices 60 is communicated to the control unit 50.

[0080] Specifically, during the drying process of the object 200 awaiting drying, the sensitivity of different film surface regions of the object 200 awaiting drying may differ. For example, under the same operating power of the heat source 30, the drying rate may be faster in some regions and slower in others. Therefore, in order to achieve uniform drying, this application provides for the installation of multiple temperature detection devices 60, which may be installed in separate regions, and at least one temperature detection device 60 may be installed in each drying region to improve the accuracy of temperature detection. Based on the film surface morphology detected by the morphology detection device 40, the control unit 50 obtains film surface differentiation information by comparing it with a stored standard film surface morphology of a uniformly dried film, and can adjust the operating power of the heat source 30 in the corresponding region in relation to the differentiation information and the temperature detected by the temperature detection device 60 in the corresponding region. For example, uniform drying can be achieved by increasing the radiant intensity of the heat source 30 in areas with a slow drying rate to raise the drying temperature and speed up the drying rate, or by decreasing the radiant intensity of the heat source 30 in areas with a fast drying rate to lower the drying temperature and slow down the drying rate. To make it clearer, "uniform drying" in this application does not mean that the temperatures within each area are all the same. Rather, assuming that the overall drying temperature is the same, it means adjusting the temperature of local areas to make the drying effect on the entire object 200 more uniform, given that different film surface areas of the object 200 awaiting drying have different sensitivities.

[0081] Specifically, the drying apparatus 100 according to this application is equipped with a morphology detection device 40, a plurality of heat sources 30, and a plurality of temperature detection devices 60. The control unit 50 controls the operating state of the plurality of heat sources 30 and adjusts the radiant intensity of each of the plurality of heat sources 30 based on the relevant information detected by the morphology detection device 40 and the plurality of temperature detection devices 60, thereby achieving a uniform drying rate and ultimately obtaining a uniformly dried film layer.

[0082] In some embodiments, the number of heat sources 30 is selectively multiple, and at least one temperature detection device 60 is installed correspondingly on the side of each heat source 30 closest to the mounting device 20.

[0083] Specifically, since each heat source 30 has a certain light-emitting area, the amount of heat released by each heat source 30 when operating covers a certain area. In this application, by installing at least one temperature detection device 60 on the side of each heat source 30 closest to the mounting device 20, the temperature within the heat-dissipating area of ​​each heat source 30 can be detected more accurately, which is advantageous for the control unit 50 to more precisely control the operating power of the heat sources 30 and achieve uniform drying.

[0084] In some embodiments, the heat source 30 is selectively fixed within the housing cavity 101, or the heat source 30 is slidably installed within the housing cavity 101.

[0085] Specifically, the different connection relationships between the heat source 30 and the housing cavity 101 are advantageous in that the appropriate type can be selected according to actual needs, thereby reducing equipment costs or improving equipment performance.

[0086] Here, multiple heat sources 30 are installed so that they can slide within the containment cavity 101. The control unit 50 controls the multiple heat sources 30 to move within the containment cavity 101 based on the film surface morphology of the drying target 200 detected by the morphology detection device 40, thereby adjusting the position of the multiple heat sources 30 within the containment cavity 101, achieving an optimal heat source 30 arrangement and improving equipment performance. Furthermore, the control unit 50 controls the operating state of the multiple heat sources 30 to form a targeted heat field, thereby achieving uniform drying of the drying target 200.

[0087] For example, the control unit 50 can increase or decrease the drying rate in a corresponding region by controlling multiple heat sources 30 to move based on the different sensitivities of different film surface regions, thereby forming heat sources 30 with different distribution densities in different film surface regions. As can be understood, the higher the distribution density of the heat sources 30, the higher the drying rate, and the lower the distribution density of the heat sources 30, the lower the drying rate.

[0088] Alternatively, the control unit 50 may control the multiple heat sources 30 to move based on the image and / or contour of the object to be dried 200, thereby forming a distributed shape corresponding to the image and / or contour of the object to be dried 200. For example, if the object to be dried 200 is circular, the control unit 50 controls the multiple heat sources 30 to move to form a corresponding circular drying area. Or, if the object to be dried 200 is rectangular, the control unit 50 controls the multiple heat sources 30 to move to form a corresponding rectangular drying area.

[0089] Specifically, the control unit 50 can improve equipment performance by changing the arrangement density of the multiple heat sources 30 in different regions and / or controlling the movement of the multiple heat sources 30 to form a distribution pattern corresponding to the surface morphology of the film to be dried, thereby contributing to achieving uniform drying of the film to be dried 200.

[0090] Here, as an implementation where the control unit 50 controls the movement of the heat source 30, a slide groove may be installed at the top of the housing cavity 101, the heat source 30 may be connected to the slide groove via a pulley, and the control unit 50 controls the movement of the pulley to control the movement of the heat source 30 within the housing cavity 101. Alternatively, a transport mechanism that is movable relative to the top of the housing cavity 101 may be installed at the top of the housing cavity 101, the heat source 30 may be suspended on the transport mechanism, and the control unit 50 moves multiple heat sources within the housing cavity 101 by controlling the movement of the transport mechanism. Specifically, the implementation where the control unit 50 controls the movement of the heat source 30 is not limited, and prior art may be applied as long as the above objective is achieved.

[0091] Alternatively, for example, multiple heat sources 30 can be installed and fixed within the housing cavity 101, forming a fixed heat field region with the multiple heat sources 30. This device has a simple structure and is advantageous for cost reduction.

[0092] In some embodiments, the heat sources 30 are selectively fixed within the containment cavity 101, and there are multiple heat sources 30. Here, the multiple heat sources 30 are uniformly distributed at the top of the containment cavity 101, or the multiple heat sources 30 form multiple heat source areas with different distribution densities at the top of the containment cavity 101.

[0093] Specifically, referring to Figure 3, the multiple heat sources 30 are fixed to the top of the containment cavity 101 and are uniformly distributed at the top of the containment cavity 101, which improves temperature uniformity and is advantageous for uniform drying. In this embodiment, the temperature detection device 60 is circular and the heat sources 30 are rectangular. The multiple heat sources 30 are arranged in a two-dimensional array, and the multiple temperature detection devices 60 are also arranged in a two-dimensional array, with multiple rows of heat sources 30 and multiple rows of temperature detection devices 60 being installed alternately, and multiple columns of heat sources 30 and multiple columns of temperature detection devices 60 being installed alternately, and one temperature detection device 60 is installed at each of the four corners of each heat source 30.

[0094] Specifically, referring to Figure 4, assuming uniform drying is ensured based on the sensitivity of the object 200 (film layer) awaiting drying, multiple heat sources 30 may be installed and fixed to the top of the housing cavity 101. Furthermore, the multiple heat sources 30 form multiple heat source areas with different distribution densities at the top of the housing cavity 101, forming different drying regions and thus creating different temperature fields when the drying operation is performed. As can be understood, the greater the distribution density of the heat sources 30, the faster the drying speed of the object 200 awaiting drying, and vice versa. If different regions within the same object have different sensitivities, and if the drying speeds of those with different sensitivities differ at the same temperature, installing multiple heat source areas with different distribution densities creates different temperature fields for regions with different sensitivities when the drying operation is performed, thereby achieving a uniform drying speed for regions with different sensitivities. In this way, assuming uniform drying is ensured, the complexity of the equipment can be significantly reduced, ultimately reducing equipment costs.

[0095] In some embodiments, selectively, the light-emitting areas of multiple heat sources 30 differ in their orthographic projection area at the bottom of the housing cavity 101.

[0096] Here, the light-emitting area can characterize the size of the heat source 30, and different light-emitting areas represent heat sources 30 of different sizes. As can be understood, when heat sources 30 with different light-emitting areas are in operation, or when heat sources 30 with the same light-emitting area are in operation, the heat dissipation areas formed on the drying object 200 will be different due to the different arrangement methods (inclined installation), and the area of ​​the drying object 200 that can be dried will be different. Furthermore, the larger the orthographic projection area of ​​the light-emitting area of ​​a single heat source 30 at the bottom of the housing cavity 101, the larger the heat dissipation area formed on the drying object 200, and the less precise the temperature control of this corresponding area becomes. The smaller the orthographic projection area of ​​the light-emitting area of ​​a single heat source 30 at the bottom of the housing cavity 101, the smaller the heat dissipation area formed on the drying object 200, and the finer the temperature control of this corresponding area becomes. When the drying awaiting film layer of the object 200 is a patterned film layer and has figures of different shapes and areas, the heat sources 30 corresponding to each figure of the drying awaiting film layer can also employ different arrangement methods and / or light emission areas, and furthermore, each figure of the drying awaiting film layer can be dried uniformly.

[0097] Here, the size of each heat source 30 may be as small as 1cm*1cm or as large. Furthermore, the shape of the heat source 30 may be designed according to actual needs, and may be, for example, a rectangle, a circle, a rhombus, or other polygon, and is not limited thereto.

[0098] Specifically, referring to Figure 5, the light-emitting surface of the heat source 30 shown in Figure 5 is installed parallel to the object 200 awaiting drying, and the size of the light-emitting area of ​​the heat source 30 can be set by the user, based on the sensitivity of the object 200 (film layer) awaiting drying, while ensuring uniform drying. For example, the drying temperature can be adjusted by reducing the size of multiple heat sources 30 in a localized area and more precisely adjusting the operating power of the heat sources 30 in that area, or the size of multiple heat sources 30 in areas where the corresponding temperature is not precisely required can be increased. In this way, while ensuring uniform drying, the complexity of the equipment can be significantly reduced, ultimately reducing equipment costs.

[0099] In some embodiments, the morphological detection device 40 selectively includes a morphological collection assembly 41, which is slidably connected to the cavity 10, or fixedly connected to the cavity 10.

[0100] Here, the slidable connection means that the morph collection assembly 41 can move relative to the cavity 10 on the inner surface of the cavity 10 by control of the control unit 50 or other external force.

[0101] Specifically, the different connection relationships between the morphological collection assembly 41 and the cavity 10 are advantageous in selecting the appropriate type according to actual needs, thereby reducing equipment costs or improving equipment performance.

[0102] Referring to Figures 3 to 6, the morphology acquisition assembly 41 and the inner surface of the cavity 10 are slidable, which is advantageous for acquiring the film surface morphology of the object 200 awaiting drying. Here, the morphology acquisition assembly 41 may be a scanning type morphology acquisition assembly 41, such as a scanner, or an imaging type morphology acquisition assembly 41, such as a camera. When the morphology detection device 40 detects the film surface morphology of the object 200 awaiting drying, the morphology acquisition assembly 41 can acquire the film surface morphology of the object 200 awaiting drying in real time by sliding the object 200 awaiting drying or scanning it back and forth and taking an image, thereby improving the acquisition performance of the device and transmitting the data to the control unit 50 to perform the corresponding operation.

[0103] In some feasible configurations, a slide rail (not shown) is provided on either the morphology collection assembly 41 or the inner surface of the cavity 10, and a slide groove (not shown) is provided on the other, so that the morphology collection assembly 41 and the cavity 10 are slidably connected via the slide rail and slide groove. Alternatively, a transport mechanism (not shown) that is movable relative to the cavity 10 is provided on the inner surface of the cavity 10, and the morphology collection assembly 41 is connected to the transport mechanism, so that the morphology collection assembly 41 and the cavity 10 are slidably connected via the transport mechanism. Specifically, the slidable connection method between the morphology collection assembly 41 and the cavity 10 provided above is structurally simple and easy to implement.

[0104] In several other feasible configurations, the morphology collection assembly 41 is fixedly connected to the cavity 10, and the morphology collection assembly 41 collects the surface morphology of the object 200 awaiting drying at a fixed angle. As can be seen, the morphology collection assembly 41 is fixedly connected to the cavity 10, eliminating the need to install a complex sliding mechanism within the cavity 10 and simplifying the instrument structure.

[0105] In some embodiments, the morphological detection device 40 selectively includes a plurality of morphological collection assemblies 41, which are arranged in an array within a housing cavity 101.

[0106] Specifically, referring to Figure 7, the multiple morphology acquisition assemblies 41 arranged in an array may be cameras, and the multiple morphology acquisition assemblies 41 may be fixedly installed to acquire real-time film surface morphology of the object 200 awaiting drying, and further transmit the data to a control unit 50 to perform the corresponding operation.

[0107] Specifically, the morphology collection assembly 41 is slidably installed within the housing cavity 101, or multiple morphology collection assemblies 41 are installed in an array within the housing cavity 101, making it easier to select the type of morphology detection device 40.

[0108] In some embodiments, multiple morphology collection assemblies 41 are selectively installed in a one-to-one correspondence with multiple temperature detection devices 60, and one morphology collection assembly 41 is integrated with one temperature detection device 60. By integrating the morphology collection assemblies 41 and temperature detection devices 60 in a one-to-one manner, the degree of integration of the equipment can be improved, making the assembly of the equipment easier and further contributing to a reduction in equipment costs.

[0109] Specifically, referring to Figure 7, the multiple morphology collection assemblies 41 and the multiple temperature detection devices 60 are all designed in a distributed manner within the housing cavity 101, and one morphology collection assembly 41 and one temperature detection device 60 are integrated into a single device. This device can not only detect the morphology of a portion of the film surface of the object 200 awaiting drying below it, but can also detect the temperature of the corresponding area, improving the degree of integration of the equipment and contributing to a reduction in equipment costs.

[0110] In some embodiments, the heat source 30 selectively includes one or more of the following: an infrared heat source, an incandescent lamp, a tungsten halogen lamp, a hot plate, and a microwave generator.

[0111] Here, the heat transfer method of the infrared heat source is radiant heat transfer, and energy is transmitted by electromagnetic waves. When infrared radiation is shone onto the object 200 awaiting drying, some of the radiation is reflected back, and some is transmitted. When the wavelength of the emitted infrared radiation matches the absorption wavelength of the object 200 awaiting drying, the object 200 awaiting drying absorbs the infrared radiation. At this time, "resonance" occurs in the molecules and atoms inside the object, causing intense vibrations and rotations. These vibrations and rotations raise the temperature of the object, achieving the goal of drying.

[0112] Here, an incandescent lamp is an electric light source that emits visible light by passing an electric current through a filament to heat it to an incandescent state and utilizing thermal radiation. Therefore, an incandescent lamp emits light using thermal radiation, has a certain heat dissipation effect, and can be used as a heat source 30.

[0113] Here, a tungsten halogen lamp is a gas-filled incandescent lamp in which some halogen elements or halides are contained in the filling gas. In order to keep the halides generated in the lamp wall in a gaseous state, the temperature of the tube wall of a tungsten halogen lamp is much higher than that of an ordinary incandescent lamp. Therefore, a tungsten halogen lamp has a certain heat dissipation effect and can be used as a heat source 30.

[0114] Here, the microwave generator can achieve a heat dissipation effect by converting electrical energy into microwave energy at its rated frequency.

[0115] Here, the hot plate may be a heat source structure formed in a plate shape using the above-mentioned infrared heat source, incandescent lamp, tungsten halogen lamp, and microwave generator, or the hot plate may be an electrical resistance plate, and is used to generate heat under energized conditions to achieve a heat dissipation function.

[0116] Specifically, the multiple types of heat sources 30 described above make it easy for users to select the type according to their actual needs, which is advantageous in selecting the appropriate heat source according to actual needs, thereby reducing equipment costs or improving equipment performance and thus enhancing market competitiveness.

[0117] In some embodiments, the temperature detection device 60 selectively includes one or more of a thermocouple temperature sensor and a thermal resistance temperature sensor.

[0118] Here, thermocouple temperature sensors are used to directly measure temperature, convert the temperature signal into a thermoelectric voltage signal, and then convert that into the temperature of the medium being measured by an electrical instrument (secondary instrument). The basic principle of temperature measurement using a thermocouple temperature sensor is as follows: A closed circuit is formed with conductors of two different materials, and when there is a temperature gradient across both ends, a current is generated passing through the circuit. At this time, an electromotive force (thermoelectric voltage) exists between the two ends, which is the so-called Seebeck effect.

[0119] A thermal resistance temperature sensor is a type of sensor thermometer that measures temperature by utilizing the principle that the resistance value of a conductor or semiconductor changes with temperature. Thermal resistance temperature sensors are broadly classified into two types: metal thermal resistors and semiconductor thermistors. Thermal resistors are widely used for temperature measurement in the range of -200 to +850°C, and in rare cases, can measure temperatures down to 1K at low temperatures and up to 1000°C at high temperatures. A thermal resistance sensor consists of a thermal resistor, connecting wires, and a display instrument. The thermal resistor may be connected to a temperature transmitter to convert the temperature into a standard current signal for output.

[0120] Specifically, the various types of temperature detection devices 60 described above make it easy for the user to select the type according to their actual needs, thereby achieving the objective of measuring the temperature of different areas within the containment cavity 101.

[0121] In some embodiments, the cavity 10 optionally further includes an airflow passage 102 that connects the cavity 101 to the outside.

[0122] Here, the airflow passage 102 refers to a passage that can be used for the flow of gas. The airflow passage may also be used to connect external equipment, and the corresponding cavity environment is realized by the external equipment.

[0123] For example, the external equipment may be a vacuum pump, which is used to create a vacuum environment by vacuuming the containment cavity 101. Here, vacuuming is the extraction of gas from inside a specific space, where the pressure is less than 1 atmosphere relative to the atmosphere, and this specific space is generally called a vacuum. The equipment used for vacuuming is called a vacuum pump, for example, a vacuum pump.

[0124] Specifically, the cavity 10 in the drying apparatus 100 according to this application further includes an airflow passage 102 that connects the outside with the housing cavity 101, and when performing drying work, the appropriate cavity 10 environment can be realized as needed. For example, it is advantageous to evacuate the housing cavity 101 to place the drying apparatus 100 under vacuum conditions and then dry the object 200 awaiting drying.

[0125] Compared to the prior art, the beneficial effects of this application are as follows. The drying apparatus 100 according to this application includes a cavity 10, a heat source 30, a morphology detection device 40, and a control unit 50. Here, the cavity 10 has a housing cavity 101, and the housing cavity 101 has a drying waiting area. The heat source 30 and the morphology detection device 40 are installed in the housing cavity 101, and when the object to be dried 200 is housed in the drying waiting area, the morphology detection device 40 detects the film surface morphology of the object to be dried 200. The control unit 50 is connected to the heat source 30 and the morphology detection device 40, respectively, and the control unit 50 controls the operating state of the heat source 30 based on the film surface morphology of the object to be dried 200 detected by the morphology detection device 40, thereby achieving uniform drying of the object to be dried 200. Furthermore, the drying apparatus 100 further includes a temperature detection device 60 installed in the containment cavity 101 and connected to the control unit 50, which is used to detect the temperature of different areas within the containment cavity 101 during the drying process. The control unit 50 then adjusts the radiant intensity of the heat source 30 in a given area based on the current temperature of that area detected by the temperature detection device 60, thereby bringing the temperature in that area within a preset temperature range and achieving uniform drying.

[0126] Referring to Figure 8, Figure 8 is a flowchart of one embodiment of the drying method for the drying apparatus according to the present application. Specifically, the present application further provides a drying method for the drying apparatus 100 used in any one of the above embodiments, which includes the following:

[0127] In step S11, the film surface morphology of the drying target 200 detected by the morphology detection device 40 is obtained.

[0128] Specifically, the control unit 50 is connected to the morphology detection device 40, and when the object to be dried 200 is placed on the placement device 20, the control unit 50 acquires the film surface morphology of the object to be dried 200 as detected by the morphology detection device 40.

[0129] In step S12, the operating state of the heat source 30 is controlled based on the film surface morphology.

[0130] Specifically, the control unit 50 is further connected to the heat source 30, and the control unit 50 controls the operating state of the heat source 30 based on the film surface morphology of the object 200 awaiting drying detected by the morphology detection device 40, thereby controlling the heat source 30 to form a targeted heat field and achieving uniform drying of the object 200 awaiting drying. Here, the number of heat sources 30 may be one or more, and the control unit 50 controlling the operating state of multiple heat sources 30 includes turning some of the heat sources 30 on and off, adjusting the radiant intensity of the multiple heat sources 30, etc. The control unit 50 controlling the operating state of one heat source 30 includes controlling this heat source 30 to move within the housing cavity 101 to the target position, adjusting the radiant intensity of this heat source 30, etc.

[0131] Specifically, this drying method allows for control of the operating state of the heat source 30 based on the film surface morphology of the drying target 200 housed in the drying waiting area, as detected by the morphology detection device 40, which is advantageous in improving the uniformity of drying for the drying target.

[0132] To simplify the explanation, the following describes the case where there are multiple heat sources 30.

[0133] In some embodiments, step S12 selectively includes obtaining film surface differentiation information based on the film surface morphology by comparing it with a stored, uniformly dried standard film surface morphology, and adjusting the operating state of the heat source 30 based on the film surface differentiation information.

[0134] Specifically, the control unit 50 may pre-store a standard film surface morphology obtained by uniformly drying the object 200 awaiting drying, and then compare it with the film surface morphology of the object 200 awaiting drying detected by the morphology detection device 40 to obtain film surface differentiation information between this film surface morphology and the standard film surface morphology, thereby controlling the operating state of the multiple heat sources 30.

[0135] Specifically, by comparing the film surface morphology with a pre-stored standard film surface morphology to obtain film surface differentiation information, it is advantageous to precisely control multiple heat sources 30 to dry the drying target 200, thereby improving the uniformity of drying.

[0136] In some embodiments, selectively adjusting the operating state of the heat source based on film surface differentiation information includes adjusting the radiant intensity of the heat source 30 corresponding to different regions of the object 200 awaiting drying based on the film surface differentiation information.

[0137] Here, there is a positive correlation between the radiant intensity of the heat source 30 and the operating power of the heat source 30. That is, the greater the operating power of the heat source 30, the greater the radiant intensity and the higher the temperature generated by the released thermal energy. Conversely, the smaller the operating power of the heat source 30, the smaller the radiant intensity and the lower the temperature generated by the released thermal energy.

[0138] Here, a heat source 30 whose amount of heat released during operation can cover a portion of the drying object 200 is the heat source 30 corresponding to this portion of the drying object 200. Here, the orthographic projection of the light-emitting surface of a heat source 30 corresponding to a different portion of the drying object 200 may completely overlap with this portion. For example, the heat source 30 may be located directly above or directly below a different portion of the drying object 200, and the orthographic projection of the light-emitting surface of the heat source 30 corresponding to a different portion of the drying object 200 may partially overlap with this portion or not overlap at all. For example, the heat source 30 may be located diagonally above or diagonally below a different portion of the drying object 200, and if the amount of heat released by the heat source 30 during operation can cover a portion of the drying object 200, then it will be the heat source 30 corresponding to this portion, and this is not limited here.

[0139] In this application, the control unit 50 adjusts the radiation intensity of the heat source 30 corresponding to different regions of the drying target 200 based on the film surface morphology detected by the morphology detection device 40 or the film surface differentiation information obtained by comparison, thereby targeting and drying different regions of the drying target 200 based on the film surface morphology of the different regions, and further improving the uniformity of drying for the drying target 200.

[0140] To understand this, when drying the object 200 awaiting drying, the drying conditions (e.g., temperature) at different stages may differ, or there may be differences in the degree of drying of different areas of the same object 200 awaiting drying. Therefore, the control unit 50 may, based on the film surface morphology detected by the morphology detection device 40, or the film surface differentiation information obtained by comparison, adjust the radiant intensity of the heat source 30 corresponding to different areas of the object 200 awaiting drying to form a targeted heat field, thereby changing the drying temperature for the object at different stages, or providing different drying temperatures to different areas of the same object 200 awaiting drying. This improves the uniformity of drying for the object 200 awaiting drying.

[0141] In some embodiments, the number of heat sources 30 is selectively multiple, and controlling the operating state of the heat sources 30 based on the film surface morphology includes controlling the heat sources 30 in the region corresponding to the object to be dried 200 to heat the object to be dried, and controlling the heat sources 30 in the region other than the object to be dried 200 to stop operating.

[0142] Specifically, the initial state of the multiple heat sources 30 may be all on, all off, or some on and some off. When the object to be dried 200 is placed on the placement device 20, the shape detection device 40 detects the film surface shape of the object to be dried 200, and the control unit 50 obtains the contour of the object to be dried 200 based on the film surface shape detected by the shape detection device 40.

[0143] The initial state of the multiple heat sources 30 may all be on, in which case the control unit 50 controls the heat sources 30 other than those in the area corresponding to the drying target 200 to stop operating.

[0144] The initial state of the multiple heat sources 30 may all be off, in which case the control unit 50 heats the drying object 200 by controlling the heat sources 30 in the area corresponding to the drying object 200 to activate.

[0145] The initial state of the multiple heat sources 30 may be partially on and partially off. In this case, the control unit 50 controls the heat sources 30 in the region corresponding to the drying target 200 to heat the drying target 200 so that they are operational, and controls the heat sources 30 other than those in the region corresponding to the drying target 200 to stop their operation.

[0146] Specifically, the control unit 50 controls the heat source 30 in the area corresponding to the drying target 200 to enable operation, thereby drying the drying target 200, and controls the heat source 30 outside the area corresponding to the drying target 200 to disable operation. In this way, it is possible to achieve uniform drying of the drying target in a targeted manner, and at the same time reduce drying costs.

[0147] In some embodiments, step S11 selectively includes obtaining an image and / or contour of the drying target 200 detected by the morphology detection device 40.

[0148] Specifically, the image refers to the surface morphology of the object 200 awaiting drying, and may be a two-dimensional or three-dimensional image. For example, the image can reflect the degree of drying, in-plane texture, in-plane wrinkles, in-plane unevenness, etc. of the object 200 awaiting drying. The contour is the boundary or outline that constitutes any single shape.

[0149] In this application, the control unit 50 acquires the shape and / or contour of the object awaiting drying 200 using the shape detection device 40, and by determining the shape boundary and / or degree of drying of the object awaiting drying, the control unit 50 can precisely control the operating state of multiple heat sources 30. For example, based on the contour of the object awaiting drying 200, the control unit 50 saves drying costs by controlling multiple heat sources 30 within the shape boundary of the object awaiting drying 200 to operate and multiple heat sources 30 outside the shape boundary of the object awaiting drying 200 to not operate. Alternatively, the control unit 50 helps to uniformly dry the object awaiting drying 200 by controlling the operating power of the heat sources 30 corresponding to different drying regions of the object awaiting drying 200 based on the shape of the object awaiting drying 200, thereby creating a targeted heat field for regions with different degrees of drying.

[0150] In some embodiments, the drying method selectively further includes controlling a plurality of heat sources 30 to move within the containment cavity 101 based on the film surface morphology.

[0151] In this application, multiple heat sources 30 are installed so that they can move within the containment cavity 101. The control unit 50 controls the multiple heat sources 30 to move within the containment cavity 101 based on the film surface morphology of the object 200 awaiting drying detected by the morphology detection device 40, thereby adjusting the position of the multiple heat sources 30 within the containment cavity 101 and realizing an optimal heat source 30 arrangement. Furthermore, by controlling the operating state of the multiple heat sources 30, the heat sources 30 are controlled to form a targeted heat field, thereby achieving uniform drying of the object 200 awaiting drying.

[0152] For example, the control unit 50 can increase or decrease the drying rate in a corresponding region by controlling multiple heat sources 30 to move based on the different sensitivities of different film surface regions, thereby forming heat sources 30 with different distribution densities in different film surface regions. As can be understood, the higher the distribution density of the heat sources 30, the higher the drying rate, and the lower the distribution density of the heat sources 30, the lower the drying rate.

[0153] Alternatively, the control unit 50 may control the multiple heat sources 30 to move based on the image and / or contour of the object to be dried 200, thereby forming a distributed shape corresponding to the image and / or contour of the object to be dried 200. For example, if the object to be dried 200 is circular, the control unit 50 controls the multiple heat sources 30 to move to form a corresponding circular drying area. Or, if the object to be dried 200 is rectangular, the control unit 50 controls the multiple heat sources 30 to move to form a corresponding rectangular drying area.

[0154] Specifically, the control unit 50 is advantageous in achieving uniform drying of the object 200 awaiting drying by changing the arrangement density of the multiple heat sources 30 in different regions and / or controlling the movement of the multiple heat sources 30 to form a distribution pattern corresponding to the surface morphology of the film to be dried.

[0155] Compared to the prior art, the beneficial effects of this application are as follows: In the drying method according to this application, the control unit 50 acquires the film surface morphology of the object awaiting drying 200 detected by the morphology detection device 40, and controls the operating state of the heat source 30 based on the film surface morphology. For example, by turning some of the heat source 30 on and off, and adjusting the operating power of the heat source 30, uniform drying of the object awaiting drying 200 is achieved by forming corresponding hot field regions within the containment cavity 101.

[0156] In one specific embodiment of this application, the drying apparatus 100 includes the cavity 10, a mounting device 20, a plurality of heat sources 30, a shape detection device 40, a temperature detection device 60, and a control unit 50. Referring to Figure 9, Figure 9 is a drying logic diagram of a drying apparatus according to one embodiment of this application, and the drying logic of the drying apparatus 100 includes the following.

[0157] Step S21: The items awaiting drying are placed on the mounting device, the storage cavity is closed, and a vacuum is applied.

[0158] In step S22, the morphology detection device detects the real-time morphology of the film surface of the object awaiting drying.

[0159] In step S23, the control unit compares the real-time film surface morphology with the stored, uniformly dried standard film surface morphology to obtain local film surface differentiation information.

[0160] In step S24, the control unit controls the heat source in the region corresponding to the object awaiting drying to activate based on local film surface differentiation information, thereby drying the object awaiting drying placed on the mounting device, and controls the heat sources other than the region corresponding to the object awaiting drying to disable them.

[0161] In step S25, the temperature detection device detects the temperature inside the containment cavity.

[0162] In step S26, the control unit acquires a preset temperature range corresponding to a certain area to be dried, and adjusts the drying speed of the area by adjusting the operating power of the heat source within the area based on the current temperature of the area detected by the temperature detection device, thereby bringing the temperature within the area within the preset temperature range.

[0163] In step S27, a uniformly dried standard film surface morphology is obtained based on detection by the morphology detection device, and a vacuum rupture is performed on the containment cavity to remove the uniformly dried object awaiting drying.
