Description

Drying device and drying method thereof Technical Field

[0001] The present application relates to the field of manufacturing, and in particular to a drying device and a drying method for the drying device. Background Art

[0002] The existing drying equipment has poor drying effect when drying the objects to be dried, which affects the product yield.

[0003] Taking solar cells as an example, solar cells are often prepared on glass coated with a transparent conductive film, wherein most of the organic layers are often applied by coating. The applied organic sol is often a liquid formula solution. After coating, it needs to be dried to evaporate the excess organic solution to form an organic film layer. However, the existing organic sol has a poor drying effect after being dried by drying equipment, resulting in an uneven organic film layer. Therefore, the existing technology urgently needs to be improved.

[0004] Summary of the Invention

[0005] In view of the above problems, the present application provides a drying device and a drying method for the drying device, which can solve the problem that the existing drying equipment has poor drying effect and causes uneven film layer formed after drying.

[0006] In a first aspect, the present application provides a drying device, comprising: a cavity having a receiving chamber; the receiving chamber having an area to be dried; a heat source disposed in the receiving chamber; the heating area of ​​the heat source covering the area to be dried; a morphology detection device disposed in the receiving chamber; the collection area of ​​the morphology detection device covering the area to be dried; and a control unit connecting the heat source and the morphology detection device. Specifically, through the above-mentioned configuration, the control unit can control the working state (position, power, on or off, etc.) of the heat source based on the film surface morphology of the object to be dried in the area to be dried detected by the morphology detection device, thereby improving the drying uniformity of the object to be dried.

[0007] In some embodiments, the number of heat sources is multiple, and the heating areas of the multiple heat sources cover different areas of the area to be dried. By providing multiple heat sources and covering different areas of the area to be dried, regional drying is achieved, which is conducive to improving the drying uniformity of the object to be dried.

[0008] In some embodiments, the drying apparatus further comprises a temperature detection device disposed within the accommodating chamber, the temperature detection device being communicatively connected to the control unit. By disposing the temperature detection device within the accommodating chamber, the control unit can adjust the radiation intensity of the heat source based on the detected temperature, thereby adjusting the drying speed, thereby facilitating uniform drying of the object to be dried.

[0009] In some embodiments, the temperature detection devices are multiple and are each communicatively connected to the control unit.

[0012] In some embodiments, the heat source is fixedly disposed within the chamber, and there are multiple heat sources; the multiple heat sources are evenly distributed across the top of the chamber; or the multiple heat sources form multiple heat source zones with varying densities across the top of the chamber. Designing the arrangement of the multiple heat sources based on actual needs can help reduce equipment costs while achieving uniform drying of the object to be dried.

[0013] In some embodiments, the topography detection device includes a topography acquisition assembly; wherein the topography acquisition assembly is slidably connected to the cavity; or, alternatively, the topography acquisition assembly is fixedly connected to the cavity.

[0015] In some embodiments, multiple profile acquisition assemblies are provided in a one-to-one correspondence with multiple temperature detection devices, and one profile acquisition assembly is integrated with one temperature detection device.

[0018] In some embodiments, the cavity further includes an airflow channel connecting the outside world and the accommodating cavity.

For example, the cavity can be vacuumed to facilitate drying of the object to be dried.

[0019] In some embodiments, the system further includes a supporting device disposed within the drying area; wherein the heat source and the supporting device are spaced apart, the supporting device being located at the bottom of the accommodating chamber; the heat source being located at the top of the accommodating chamber; and the topography detection device being located between the supporting device and the heat source. Specifically, the supporting device is used to support the object to be dried, and by arranging the relative positions of the heat source, the supporting device, and the topography detection device, the arrangement of the components within the accommodating chamber is optimized so that the components do not interfere with each other during operation.

[0020] In a second aspect, the present application provides a drying method for a drying apparatus, applicable to any of the aforementioned drying apparatuses, the drying method comprising: obtaining a film surface topography of an object to be dried as detected by a topography detection device; and controlling the operating state of a heat source based on the film surface topography. Specifically, the drying method can control the operating state of the heat source based on the film surface topography of the object to be dried within the drying area as detected by the topography detection device, thereby facilitating improved drying uniformity of the object to be dried.

[0021] In some embodiments, controlling the operating state of the heat source based on the membrane surface topography includes: obtaining membrane surface differentiation information based on the membrane surface topography compared with a stored standard membrane surface topography for uniform drying; and adjusting the operating state of the heat source based on the membrane surface differentiation information. Specifically, obtaining the membrane surface differentiation information by comparing the membrane surface topography with the stored standard membrane surface topography facilitates targeted control of the heat source to dry the object to be dried, thereby improving drying uniformity.

[0022] In some embodiments, adjusting the operating state of the heat source based on the membrane surface differentiation information includes adjusting the radiation intensity of the heat source corresponding to different regions of the object to be dried based on the membrane surface differentiation information. Specifically, the radiation intensity of the heat source corresponding to different regions of the object to be dried is adjusted based on the membrane surface differentiation information to achieve targeted drying of different regions of the object to be dried, thereby improving drying uniformity of the object to be dried.

[0023] In some embodiments, there are multiple heat sources; controlling the operating state of the heat sources based on the film surface topography includes: controlling the heat sources in the area corresponding to the object to be dried to heat the object to be dried; and controlling the heat sources outside the area corresponding to the object to be dried to stop operating. This not only ensures uniform drying of the object to be dried, but also reduces costs by stopping the heat sources outside the area corresponding to the object to be dried.

[0024] In some embodiments, acquiring the film surface topography of the object to be dried as detected by the topography detection device includes acquiring an image and / or outline of the object to be dried as detected by the topography detection device. Specifically, by detecting the image and / or outline of the object to be dried, the control unit can determine the shape boundary and / or dryness level of the object to be dried, thereby specifically controlling the operating states of the multiple heat sources to facilitate uniform drying of the object to be dried.

[0025] In some embodiments, the method further includes controlling the movement of the heat source within the accommodating chamber based on the membrane surface topography. Specifically, the method controls the movement of the heat source within the accommodating chamber based on the membrane surface topography, and can adjust the positions of the multiple heat sources according to the membrane surface topography of the object to be dried, thereby achieving an optimal heat source arrangement, thereby facilitating uniform drying of the object to be dried.

[0044] Solar cells utilize the principle of photoelectric conversion, converting solar radiation into electrical energy through a semiconductor material. This photoelectric conversion process is often called the "photovoltaic effect," and hence, solar cells are also known as "photovoltaic cells." Currently, market developments indicate that solar cells are increasingly being used. They are not only used in energy storage power systems, but also in electric vehicles such as electric vehicles, as well as in military equipment and aerospace applications. As the application areas of solar cells continue to expand, market demand is also growing.

[0045] Among them, the preparation of solar cells usually includes the step of coating an organic sol formula solution on glass coated with a transparent conductive film to form an organic film layer. The organic sol formula solution forming the organic film layer needs to be dried to volatilize the excess organic solution, and the drying and volatilization process requires that the formed organic film layer is very uniform.

[0046] However, the inventors of the present application discovered that:

[0047] 1. The industrialized size of solar cells is large, and existing drying equipment mostly uses air flow field drying, which makes it difficult to achieve uniform drying.

[0048] 2. Considering the need to adapt to different solar cell product specifications, when the battery size changes, the heat field in a single area is difficult to meet uniform drying conditions.

[0049] Among them, existing drying equipment generally includes devices that can generate radiant heat and / or devices that generate airflow, and dries the objects to be dried through radiant heat and flowing airflow. It is widely used in manufacturing fields, such as display panel manufacturing, solar cell preparation, etc.

[0050] In order to solve the problem of uneven drying of the objects to be dried by existing drying equipment, the applicant has discovered that the thermal field in different areas of the drying equipment can be controlled, and the membrane surface morphology of the object to be dried can be obtained. Based on the membrane surface morphology of the object to be dried, the corresponding thermal field can be controlled to dry the object to be dried, thereby achieving the purpose of uniform drying.

[0051] Based on the above considerations, in order to solve the problem of uneven drying of the objects to be dried by existing drying equipment, the inventors have proposed the following technical solutions after in-depth research.

[0052] Please refer to Figures 1 to 7, Figure 1 is a structural schematic diagram of an embodiment of the drying equipment provided by the present application; Figure 2 is a structural schematic diagram of another embodiment of the drying equipment provided by the present application; Figure 3 is a top view of an embodiment of the drying equipment provided by the present application within the accommodating chamber; Figure 4 is a top view of another embodiment of the drying equipment provided by the present application within the accommodating chamber; Figure 5 is a top view of another embodiment of the drying equipment provided by the present application within the accommodating chamber; Figure 6 is a top view of another embodiment of the drying equipment provided by the present application within the accommodating chamber; Figure 7 is a top view of another embodiment of the drying equipment provided by the present application within the accommodating chamber.

[0053] The present application designs a drying device 100, including a cavity 10, a heat source 30, a morphology detection device 40 and a control unit 50; wherein the cavity 10 has a accommodating cavity 101, and the accommodating cavity 101 has an area to be dried; the heat source 30 is arranged in the accommodating cavity 101, and the heating area of ​​the heat source 30 covers the area to be dried, and is used to release heat under working conditions to dry the object to be dried 200 located in the area to be dried; the morphology detection device 40 is arranged in the accommodating cavity 101, and the collection area of ​​the morphology detection device 40 covers the area to be dried, and is used to detect the film surface morphology of the object to be dried 200 located in the area to be dried; the control unit 50 is connected to the heat source 30 and the morphology detection device 40 respectively; the control unit 50 controls the working 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 controlling the heat source 30 to form a targeted thermal field to achieve uniform drying of the object to be dried.

[0054] The cavity 10 is a housing of a device that includes a storage space. In this application, the cavity 10 includes a storage chamber 101, which is used to accommodate the heat source 30, the shape detection device 40, and the object to be dried 200. The shape and size of the cavity 10 are not limited and can be designed as needed. In this application, the cavity 10 is a metal housing.

[0055] The heat source 30 refers to a component capable of releasing heat energy under operating conditions, such as a heat-radiating lamp, infrared light source, microwave generator, etc. There can be multiple heat sources 30. These multiple heat sources 30 can be independent and spaced or arranged in a non-spaced manner. Alternatively, a single heat source device can include multiple independently controllable heat-releasing regions, with the multiple heat-releasing regions representing multiple heat sources 30. Alternatively, there can be only one heat source 30, slidably connected to the cavity 10, allowing the heat source 30 to be movably disposed within the accommodating cavity 101.

[0056] The area to be dried is the area covered by the heat energy released by the heat source 30 under working conditions. The area to be dried is used to accommodate the object to be dried 200 so that the object to be dried 200 can be dried by the heat source 30 when working.

[0057] The object to be dried 200 is a substance that needs to be dried, such as a film layer to be solidified, a liquid, a semi-solid, or a solid substance containing a certain liquid content. The object to be dried 200 includes but is not limited to the organosol formula solution described above in this application. When the object to be dried 200 is located in the area to be dried, the object to be dried 200 needs to have a certain degree of support. For example, the object to be dried 200 can be supported by a substrate (glass substrate, etc.), and then the substrate can be placed in the area to be dried. In this application, the object to be dried 200 is a transparent conductive glass coated with an organosol formula solution.

[0058] The topography detection device 40 is a device that uses scanning, video recording, or other methods to obtain the topography of the film surface of the object to be dried 200. Specifically, by detecting the topography of the film surface of the object to be dried 200 through the topography detection device 40, the control unit 50 can determine the shape and / or dryness of the object to be dried 200. Based on this topography, the control unit 50 can then specifically control the operating state of the heat source 30 to facilitate uniform drying of the object to be dried 200.

[0059] Among them, the control unit 50 generally includes a processor and a memory, and the processor can also be called a CPU (Central Processing Unit). The processor may be an integrated circuit chip with signal processing capabilities. The processor can also be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc. The memory can be a memory stick, a TF card, etc., which can store all the information in the device, including the input raw data, computer programs, intermediate operation results and final operation results, all of which are stored in the memory. It stores and retrieves information according to the location specified by the processor. With the memory, the control unit 50 has a memory function and can ensure normal operation. In the present application, the control unit 50 is arranged on the outer side of the cavity 10, and can also be arranged on the outside of the cavity 10 and spaced apart from the cavity 10, which is not limited here.

[0060] Specifically, when the drying equipment 100 dries the object to be dried 200, it is necessary to first transfer the object to be dried 200 to the drying area in the accommodating chamber 101 through a mechanical grabber, a conveyor belt, etc., and then close the accommodating chamber 101. The morphology detection device 40 detects the film surface morphology of the object to be dried 200, and the control unit 50 controls the working state of one / multiple heat sources 30 according to the film surface morphology detected by the morphology detection device 40; or the control unit 50 compares the film surface morphology detected by the morphology detection device 40 with the stored standard film surface morphology of uniform drying, and then obtains the film surface differentiation information, and then controls the working state of one / multiple heat sources 30 according to the film surface differentiation information. The control unit 50 controls the working state of one heat source 30, including controlling the heat source 30 to move to a target position in the accommodating chamber 101, adjusting the working power of one heat source 30, etc., thereby drying the object 200 to be dried. The control unit 50 controls the working state of multiple heat sources 30, including turning on and off some of the heat sources 30, adjusting the radiation intensity of the multiple heat sources 30, etc. After a period of drying, a uniformly dried film surface is obtained, and finally the uniformly dried object 200 to be dried is removed from the accommodating chamber 101 for use. The control unit 50 controls the working state of multiple heat sources 30, including turning on and off some of the heat sources 30, adjusting the working power of the multiple heat sources 30, etc., so that corresponding thermal field areas are formed in the accommodating chamber 101, thereby drying the object 200 to be dried. After a period of drying, a uniformly dried film surface is obtained, and finally the uniformly dried object 200 to be dried is removed from the accommodating chamber 101 for use.

[0061] It can be understood that the present application detects the film surface morphology of the object to be dried 200 through the morphology detection device 40, and the control unit 50 controls the working state of the heat source 30 based on the film surface information detected by the morphology detection device 40, thereby forming a targeted thermal field according to the film surface morphology of the object to be dried 200, and achieving uniform drying of the object to be dried 200. Therefore, when facing the problem of uneven drying of large-sized and / or different-sized solar cells, the drying device 100 provided by the present application can detect the film surface morphology in real time through the morphology detection device 40 and compare it with the standard uniform drying film surface morphology. According to the differentiated morphology, the control unit 50 controls the working state of the heat source 30, for example, adjusting the working power of the heat source 30 in the corresponding area, thereby achieving uniform drying of the entire film surface. Since the object to be dried 200 of the present application is a two-dimensional thin film with a small thickness, the drying uniformity of the object to be dried 200 is mainly in the film direction parallel to the object to be dried 200, that is, the horizontal direction. Therefore, the present application divides the accommodating chamber 101 into a plurality of drying areas along the horizontal direction, and one or more heat sources 30 are correspondingly provided in each drying area, or a movable heat source 30 is used to dry different drying areas.

[0062] In some embodiments, optionally, there are multiple heat sources 30 , and the control unit 50 controls the heat sources 30 in the area corresponding to the object 200 to heat the object 200 to be dried, and controls the heat sources 30 outside the area corresponding to the object 200 to stop working.

[0063] The heat released by each heat source 30 during operation covers a certain area of ​​the object 200 to be dried, which is the area corresponding to the heat source 30 and the object 200 to be dried. The heat source 30 corresponding to the area of ​​the object 200 to be dried refers to all heat sources 30 that release heat covering the object 200 to be dried during operation.

[0064] Specifically, the initial states of the multiple heat sources 30 can be all on, all off, or partially on and partially off. When the object 200 to be dried is carried on the carrying device 20, the topography detection device 40 detects the film surface topography of the object 200 to be dried. The control unit 50 determines the contour of the object 200 based on the film surface topography detected by the topography detection device 40. The control unit 50 then controls the heat sources 30 in the area corresponding to the object 200 to heat the object 200 to dry it, and controls the heat sources 30 outside the area corresponding to the object 200 to stop operating. In other words, the heat sources 30 outside the area corresponding to the object 200 are controlled to be inoperative. This not only achieves targeted and uniform drying of the object 200 to be dried, but also reduces drying costs.

[0065] Among them, the initial state of multiple heat sources 30 can be all turned on, that is, when the object to be dried 200 is not in the drying area, or just in the drying area, the multiple heat sources 30 are all in working state, so that the drying operation can be started when the object to be dried 200 enters the accommodating chamber 101, thereby improving the drying efficiency.

[0066] The initial state of the multiple heat sources 30 can be all closed, that is, when the object 200 to be dried is not in the drying area, or just in the drying area, the multiple heat sources 30 are not working, which can save costs and reduce energy waste.

[0067] The initial states of the multiple heat sources 30 can be partially on and partially off. For example, the initial states of the multiple heat sources 30 can be the final states at the end of the previous drying cycle. Alternatively, the shape of the object 200 to be dried can be estimated, and some of the heat sources 30 can be turned on or off in advance. After the control unit 50 obtains the film surface morphology of the object 200 to be dried, some of the heat sources 30 can be turned on or off to adjust the state. This improves drying efficiency while saving costs.

[0068] When there is only one heat source 30, if the heat source 30 is located outside the area corresponding to the object 200 to be dried, the control unit 50 controls the heat source 30 to move from outside the area corresponding to the object 200 to the area corresponding to the object 200 to be dried, and turns on the heat source 30 to evenly dry the object 200. If the heat source 30 is located in the area corresponding to the object 200 to be dried, the control unit 50 controls the heat source 30 to turn on to evenly dry the object 200.

[0069] For the convenience of description, the following description will be made based on the case where there are multiple heat sources 30 .

[0070] In some embodiments, optionally, the control unit 50 adjusts the radiation intensity of the heat source 30 in the area corresponding to the object 200 to be dried to dry the object.

[0071] Specifically, the radiation intensity of the heat source 30 is positively correlated with the working power of the heat source 30 , that is, the greater the working power of the heat source 30 , the greater the radiation intensity, the higher the temperature generated by the released heat energy, and vice versa.

[0072] In the present application, the control unit 50 adjusts the radiation intensity of the heat source 30 in the area corresponding to the object to be dried 200 according to the film surface morphology detected by the morphology detection device 40, or the film surface differentiation information obtained through comparison, so as to dry the object to be dried 200 in a targeted manner, thereby improving the drying uniformity of the object to be dried 200.

[0073] It is understandable that when the object to be dried 200 is dried, the drying conditions (such as temperature) may be different at different stages, or the degree of drying in different areas of the same object to be dried 200 may also be different. Therefore, the control unit 50 adjusts the radiation intensity of the heat source 30 in the area corresponding to the object to be dried 200 according to the film surface morphology detected by the morphology detection device 40, or the film surface differentiation information obtained through comparison, thereby forming a targeted thermal field, so as to change the drying temperature of the object to be dried at different stages, or provide different drying temperatures for different areas of the same object to be dried 200, so as to improve the drying uniformity of the object to be dried 200.

[0074] In some embodiments, optionally, the film surface topography includes an image and / or outline of the object to be dried.

[0075] The image refers to the surface morphology of the object to be dried 200 and can be a two-dimensional or three-dimensional image. For example, the image can reflect the dryness, surface texture, surface wrinkles, surface unevenness, etc. of the object to be dried 200.

[0076] Among them, the outline is the boundary or outline that constitutes any shape.

[0077] In the present application, the shape and / or contour of the object 200 to be dried is detected by the shape detection device 40, so that the control unit 50 can determine the shape boundary and / or dryness degree of the object to be dried, thereby controlling the operating states of the multiple heat sources 30 in a targeted manner. For example, the control unit 50 controls the multiple heat sources 30 within the shape boundary of the object to be dried 200 to operate based on the contour of the object to be dried 200, and controls the multiple heat sources 30 outside the shape boundary of the object to be dried to not operate, thereby saving drying costs; or the control unit 50 adjusts the radiation intensity of the heat sources 30 corresponding to different drying areas of the object to be dried 200 based on the shape of the object to be dried 200, so as to form targeted thermal fields for areas with different dryness degrees, thereby facilitating uniform drying of the object to be dried 200.

[0078] In some embodiments, optionally, referring to Figure 2, the drying equipment 100 further includes a carrying device 20, which is arranged in the area to be dried; wherein the heat source 30 and the carrying device 20 are spaced apart, and the carrying device 20 is located at the bottom of the accommodating cavity 101; the heat source 30 is located at the top of the accommodating cavity 101; and the morphology detection device 40 is located between the carrying device 20 and the heat source 30.

[0079] The carrying device 20 is used to provide a stable carrying surface for the object 200 to be dried. Specifically, the carrying device 20 can be an object with a carrying surface, or the carrying surface can be composed of multiple carrying columns, as long as the object 200 to be dried can be stably carried on the carrying device 20.

[0080] Specifically, the carrier device 20 is used to support the object 200 to be dried. During the drying process, the object 200 is positioned in the drying area. Multiple heat sources 30 can be disposed on the surface of the carrier device 20 supporting the object 200, in contact with the object 200 to increase the drying rate. Alternatively, the heat sources 30 can be disposed within the carrier device 20. The carrier device 20 can be made of a material with good thermal conductivity, and the heat sources 30 can indirectly transfer heat to the object 200 by heating the carrier device 20. This arrangement allows for a rapid heat transfer rate from the heat sources 30 to the object 200, thereby improving drying efficiency. Furthermore, the presence of multiple heat sources 30 within or on the surface of the carrier device 20 improves the device's integration and does not affect the installation space for other components (such as the topography detection device 40).

[0081] The term "separated arrangement" refers to a certain distance between the heat source 30 and the carrier device 20, without contact. The carrier device 20 can be structured in any manner and may include a platform or a bracket having a support surface. Specifically, the separation between the heat source 30 and the carrier device 20 facilitates the separate installation and replacement of the heat source 30 or the carrier device 20.

[0082] The top and bottom of the accommodating chamber 101 are two opposing areas within the accommodating chamber 101. The bottom is the area of ​​the chamber space closer to the ground, and the top is the area of ​​the chamber space farther from the ground. Placing the carrier 20 at the bottom of the accommodating chamber 101 facilitates the loading of the object 200 to be dried. Placing the heat source 30 at the top of the accommodating chamber 101, opposite and spaced from the carrier 20, does not affect the heat source 30's ability to dry the object 200 carried on the carrier 20. The topography detection device 40 is disposed between the carrier 20 and the heat source 30. When the topography detection device 40 detects the film surface topography of the object 200 carried on the carrier 20 below it, the heat source 30 does not interfere with the detection. For example, when the topography detection device 40 employs a sliding scanning detection method, the heat source 30 and the carrier 20 do not obstruct the sliding path of the topography detection device 40 as it slides. When the heat source 30 dries the object 200 to be dried, the shape detection device 40 can slide close to the side wall of the accommodating cavity 101 , and the shape detection device 40 will not block the heat source 30 .

[0083] Specifically, by optimizing the arrangement of the heat source 30 , the shape detection device 40 , and the carrying device 20 in the accommodating cavity 101 , the components do not affect each other during operation.

[0084] In some embodiments, optionally, there are multiple heat sources 30, and the heating areas of the multiple heat sources 30 cover different areas of the area to be dried.

[0085] Specifically, by providing multiple heat sources 30 covering different areas of the drying area, regional drying is achieved, thereby improving the uniformity of drying the object being dried. For example, if the drying degree varies across different areas of the membrane surface of the same object 200, the control unit 50 adjusts the radiation intensity of the corresponding heat sources 30 based on the different membrane surface areas of the object 200, forming a targeted thermal field and thus improving drying uniformity.

[0086] In some embodiments, optionally, please continue to refer to FIG. 1 , the drying device 100 further includes a temperature detection device 60 , which is disposed in the accommodating cavity 101 , and the temperature detection device 60 is further communicatively connected to the control unit 50 .

[0087] Among them, the temperature detection device 60 refers to a device for detecting the temperature of the environment to be tested, the object to be tested, etc. In this application, the temperature detection device 60 is used to detect the temperature in the accommodating cavity 101 and / or the membrane surface temperature of the object to be dried 200, and output the detection results to the control unit 50 by wired transmission or wireless communication.

[0088] In the present application, by setting a temperature detection device 60 in the accommodating chamber 101, the temperature detection device 60 can be set in the accommodating chamber 101 through a bracket or a hanger. For example, a lifting rod is installed on the top wall of the accommodating chamber 101, and the temperature detection device 60 is fixed to the bottom end of the lifting rod. The lifting rod can place the temperature detection device 60 in different height areas. It can be understood that 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. Among them, the temperature detection device 60 is used to sense the temperature in the area and convert it into a usable output signal to the control unit 50, so that the control unit 50 adjusts the radiation intensity of the corresponding heat source 30 based on the temperature of the area detected by the temperature detection device 60, so that the temperature in the area is within the preset temperature range, thereby achieving uniform drying.

[0089] In some embodiments, optionally, there are multiple temperature detection devices 60; the multiple temperature detection devices 60 are respectively communicatively connected to the control unit 50.

[0090] Specifically, during the drying process of the object to be dried 200, different film surface areas of the object to be dried 200 may have different sensitivities. For example, under the same working power of the heat source 30, some areas may dry quickly while other areas dry slowly. Therefore, in order to achieve uniform drying, the present application sets a plurality of temperature detection devices 60, and the plurality of temperature detection devices 60 can be set in different areas. At least one temperature detection device 60 can be set in each drying area to improve the accuracy of temperature detection. The control unit 50 can compare the film surface morphology detected by the morphology detection device 40 with the stored standard film surface morphology for uniform drying, and then obtain differentiated information of the film surface. Based on the differentiated information and the temperature detected by the temperature detection device 60 in the corresponding area, the working power of the heat source 30 in the corresponding area is adjusted, such as increasing the radiation intensity of the heat source 30 in the area with a slower drying speed to increase the drying temperature and speed up the drying rate; or reducing the radiation intensity of the heat source 30 in the area with a faster drying speed to reduce the drying temperature and slow down the drying rate, thereby achieving uniform drying. It can be understood that the "uniform drying" of the present application does not mean making the temperature in each area consistent, but under the premise of consistent overall drying temperature, the temperature of the local area is adjusted according to the different sensitivities of different membrane surface areas of the object to be dried 200, so that the drying effect of the entire object to be dried 200 is more uniform.

[0091] Specifically, the drying equipment 100 provided in the present application is provided with a morphology detection device 40, multiple heat sources 30 and multiple temperature detection devices 60. The control unit 50 can control the working status of the multiple heat sources 30 based on the relevant information detected by the morphology detection device 40 and the multiple temperature detection devices 60, and adjust the radiation intensity of the multiple heat sources 30 respectively, so as to achieve uniform drying speed and finally obtain a uniformly dried film layer.

[0092] In some embodiments, optionally, there are multiple heat sources 30 , and at least one temperature detection device 60 is correspondingly provided on a side of each heat source 30 close to the carrier device 20 .

[0093] Specifically, since each heat source 30 has a certain light-emitting area, the heat released by each heat source 30 when working covers a certain area. In the present application, by setting at least one temperature detection device 60 on the side of each heat source 30 close to the supporting device 20, the temperature within the heat-releasing area of ​​each heat source 30 can be detected more accurately, which is conducive to the control unit 50 to more accurately control the working power of the heat source 30 and achieve uniform drying.

[0094] In some embodiments, optionally, the heat source 30 is fixedly disposed in the accommodating cavity 101 , or the heat source 30 is slidably disposed in the accommodating cavity 101 .

[0095] Specifically, different connection relationships between the heat source 30 and the accommodating cavity 101 are conducive to appropriate selection based on actual needs, thereby reducing equipment costs or improving equipment performance.

[0096] Specifically, multiple heat sources 30 are arranged to slide within the accommodating chamber 101. The control unit 50 can control the movement of the multiple heat sources 30 within the accommodating chamber 101 based on the film surface morphology of the object 200 to be dried detected by the morphology detection device 40, thereby adjusting the position of the multiple heat sources 30 within the accommodating chamber 101 to achieve an optimal arrangement of the heat sources 30 and improve equipment performance. The control unit 50 can further control the operating status of the multiple heat sources 30, thereby controlling the heat sources 30 to form a targeted thermal field and achieve uniform drying of the object to be dried.

[0097] For example, the control unit 50 can control the movement of multiple heat sources 30 to form different distribution densities of heat sources 30 in different film surface areas based on the different sensitivities of different film surface areas, thereby correspondingly increasing or decreasing the drying rate in the corresponding areas. It is understood that a greater distribution density of heat sources 30 results in a higher drying rate, while a smaller distribution density of heat sources 30 results in a lower drying rate.

[0098] Alternatively, the control unit 50 may control the movement of the multiple heat sources 30 based on the image and / or outline of the object 200 to be dried so that the multiple heat sources 30 form a distribution pattern corresponding to the image and / or outline of the object 200 to be dried. For example, if the object 200 to be dried is circular, the control unit 50 controls the movement of the multiple heat sources 30 to form a corresponding circular drying area. Alternatively, if the object 200 to be dried is rectangular, the control unit 50 controls the movement of the multiple heat sources 30 to form a corresponding rectangular drying area.

[0099] Specifically, the control unit 50 controls the movement of multiple heat sources 30 to change the arrangement density of the multiple heat sources 30 in different areas, and / or forms a distribution pattern corresponding to the film surface morphology of the object to be dried, which can improve the equipment performance and thus facilitate the uniform drying of the object to be dried 200.

[0100] The control unit 50 may control the movement of the heat source 30 by providing a chute at the top of the accommodating chamber 101, with the heat source 30 connected to the chute via a pulley, and the control unit 50 controlling the movement of the pulley to control the movement of the heat source 30 within the accommodating chamber 101. Alternatively, a transport mechanism movable relative to the top of the accommodating chamber 101 may be provided at the top of the accommodating chamber 101, with the heat source 30 suspended on the transport mechanism, and the control unit 50 controlling the movement of the transport mechanism to move multiple heat sources within the accommodating chamber 101. Specifically, the control unit 50 is not limited to any specific method for controlling the movement of the heat source 30, and existing technologies may be applied as long as the aforementioned purpose can be achieved.

[0101] For another example, multiple heat sources 30 are fixed in the accommodating cavity 101 , and the multiple heat sources 30 form a fixed thermal field area. This device has a simple structure and is conducive to reducing costs.

[0102] In some embodiments, optionally, the heat source 30 is fixedly arranged in the accommodating cavity 101, and the number of heat sources 30 is multiple; wherein, the multiple heat sources 30 are evenly distributed on the top of the accommodating cavity 101; or, the multiple heat sources 30 form multiple heat source areas with different distribution densities on the top of the accommodating cavity 101.

[0103] Specifically, referring to Figure 3 , multiple heat sources 30 are fixed to the top of the accommodating chamber 101 and evenly distributed across the top of the accommodating chamber 101, which can improve temperature uniformity and facilitate uniform drying. In this embodiment, the temperature detection device 60 is circular and the heat source 30 is 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. Multiple rows of heat sources 30 are alternately arranged with multiple rows of temperature detection devices 60, and multiple columns of heat sources 30 are alternately arranged with multiple columns of temperature detection devices 60. A temperature detection device 60 is provided at each of the four corners of each heat source 30.

[0104] Specifically, referring to FIG4 , it is also possible to set a plurality of heat sources 30 fixed to the top of the accommodating chamber 101 based on the sensitivity of the object 200 (film layer) to be dried, while ensuring uniform drying, and the plurality of heat sources 30 form a plurality of heat source zones with different distribution densities at the top of the accommodating chamber 101 to form different drying areas, thereby forming different temperature fields during the drying operation. It is understandable that the greater the distribution density of the heat source 30, the faster the drying rate of the object 200 to be dried, and vice versa. If the sensitivity of different areas within the same drying object is different, and the drying rates of different sensitivities are different at the same temperature, by setting a plurality of heat source zones with different distribution densities, different temperature fields can be formed for different sensitive areas during the drying operation, achieving consistent drying rates for different sensitive areas. In this way, while ensuring uniform drying, the complexity of the equipment can be significantly reduced, and ultimately the equipment cost can be reduced.

[0105] In some embodiments, optionally, the light emitting areas of the plurality of heat sources 30 have different orthographic projection areas on the bottom of the accommodating cavity 101 .

[0106] Among them, the light emitting area can represent the size of the heat source 30, and different light emitting areas represent heat sources 30 of different sizes. It can be understood that when the heat sources 30 with different light emitting areas are working, or the heat sources 30 with the same light emitting area have different arrangements (tilted settings), the heat release areas formed on the object to be dried 200 are different, and the areas that can dry the object to be dried 200 are different. And the larger the area of ​​the orthographic projection of the light emitting area of ​​a single heat source 30 on the bottom of the accommodating cavity 101, the larger the heat release area formed on the object to be dried 200, and the less precise the temperature regulation of the corresponding area; the smaller the area of ​​the orthographic projection of the light emitting area of ​​a single heat source 30 on the bottom of the accommodating cavity 101, the smaller the heat release area formed on the object to be dried 200, and the more precise the temperature regulation of the corresponding area. When the film layer to be dried of the object to be dried 200 is a patterned film layer having patterns of different shapes and areas, the heat sources 30 corresponding to each pattern of the film layer to be dried also adopt different arrangements and / or light output areas, thereby enabling each pattern of the film layer to be dried to be evenly dried.

[0107] The size of each heat source 30 can be as small as 1 cm*1 cm or as large as 1 cm. The shape of the heat source 30 can be designed according to actual needs, for example, it can be rectangular, circular, diamond or other polygonal, etc., which is not limited here.

[0108] Specifically, please refer to Figure 5. The light-emitting surface of the heat source 30 in Figure 5 is arranged parallel to the object to be dried 200. According to the sensitivity of the object to be dried 200 (film layer), the size of the light-emitting area of ​​the heat source 30 can be set independently while ensuring uniform drying. For example, the sizes of multiple heat sources 30 in a local area are smaller to more accurately adjust the working power of the heat source 30 in the area and thus adjust the drying temperature. In addition, the sizes of multiple heat sources 30 in areas with less precise temperature requirements can be larger. In this way, while ensuring uniform drying, the complexity of the equipment can be significantly reduced, and ultimately the equipment cost can be reduced.

[0109] In some embodiments, optionally, the shape detection device 40 includes a shape acquisition component 41 , wherein the shape acquisition component 41 and the cavity 10 are slidably connected; or, the shape acquisition component 41 and the cavity 10 are fixedly connected.

[0110] The slidable connection means that the shape acquisition component 41 can move relative to the cavity 10 on the inner surface of the cavity 10 under the control of the control unit 50 or other external forces.

[0111] Specifically, different connection relationships between the topography acquisition component 41 and the cavity 10 are conducive to appropriate selection based on actual needs, thereby reducing equipment costs or improving equipment performance.

[0112] Referring to Figures 3-6 , the topography acquisition component 41 slides along the inner surface of the chamber 10, facilitating the acquisition of the membrane surface topography of the object 200 to be dried. Specifically, the topography acquisition component 41 can be a scanning component 41, such as a scanner, or a video component 41, such as a camera. When the topography detection device 40 detects the membrane surface topography of the object 200 to be dried, the topography acquisition component 41 can slide to acquire or reciprocally scan and photograph the object 200, thereby obtaining a real-time image of the membrane surface topography of the object 200 to be dried, improving the device's acquisition performance, and then transmitting the image to the control unit 50 for appropriate operation.

[0113] In some embodiments, one of the inner surfaces of the profile collection assembly 41 and the cavity 10 is provided with a slide rail (not shown), and the other is provided with a slide groove (not shown), and the profile collection assembly 41 and the cavity 10 are slidably connected via the slide rail and the slide groove. Alternatively, the inner surface of the cavity 10 is provided with a transmission mechanism (not shown) that is movable relative to the cavity 10, and the profile collection assembly 41 is connected to the transmission mechanism, and the profile collection assembly 41 and the cavity 10 are slidably connected via the transmission mechanism. Specifically, the slidable connection between the profile collection assembly 41 and the cavity 10 provided above is simple in structure and easy to implement.

[0114] In other embodiments, the topography collection assembly 41 is fixedly connected to the chamber 10, and the topography collection assembly 41 collects the film surface topography of the object to be dried 200 at a fixed angle. It will be appreciated that the fixed connection between the topography collection assembly 41 and the chamber 10 eliminates the need for a complex sliding mechanism within the chamber 10, thereby simplifying the device structure.

[0115] In some embodiments, optionally, the shape detection device 40 includes a plurality of shape acquisition components 41 , and the plurality of shape acquisition components 41 are arranged in an array in the accommodating cavity 101 .

[0116] Specifically, referring to FIG. 7 , the multiple morphology acquisition components 41 arranged in an array may be cameras, and the multiple morphology acquisition components 41 may be fixedly arranged to acquire the real-time film surface morphology of the object to be dried 200 , and then transmit the real-time morphology to the control unit 50 for corresponding operation.

[0117] Specifically, the shape acquisition component 41 can be slidably disposed in the accommodating cavity 101 , or a plurality of shape acquisition components 41 can be arranged in an array in the accommodating cavity 101 , which can facilitate the selection of the shape detection device 40 .

[0118] In some embodiments, optionally, multiple profile acquisition components 41 are provided in a one-to-one correspondence with multiple temperature detection devices 60, and one profile acquisition component 41 is integrated with one temperature detection device 60. By integrating the profile acquisition component 41 with the temperature detection device 60 one-to-one, the integration of the device can be improved, the device assembly is facilitated, and the device cost is reduced.

[0119] Specifically, please continue to refer to Figure 7. Multiple morphology acquisition components 41 and multiple temperature detection devices 60 are all distributed in the accommodating cavity 101, and one morphology acquisition component 41 and one temperature detection device 60 are integrated into one device. The device can not only detect the partial membrane surface morphology of the object to be dried 200 thereunder, but also detect the temperature of the corresponding area, which can improve the integration of the equipment and help reduce the equipment cost.

[0120] In some embodiments, optionally, the heat source 30 includes one or more of an infrared heat source, an incandescent lamp, a halogen lamp, a hot plate, and a microwave generator.

[0121] Infrared heat sources transfer heat through radiation, transferring energy via electromagnetic waves. When infrared radiation strikes the object 200 to be dried, some of the radiation is reflected, while some penetrates. When the wavelength of the emitted infrared radiation matches the absorption wavelength of the object 200, the object absorbs the infrared radiation. This causes the molecules and atoms within the object to resonate, generating intense vibration and rotation. These vibrations and rotations raise the object's temperature, achieving the desired drying effect.

[0122] Among them, the incandescent lamp is an electric light source that heats the filament to an incandescent state by electricity and emits visible light by thermal radiation. Therefore, since the incandescent lamp emits light by thermal radiation, it has a certain heat release effect and can be used as the heat source 30.

[0123] Halogen lamps are gas-filled incandescent lamps whose gas contains some halogen elements or halides. To keep the halides generated at the lamp wall in a gaseous state, the wall temperature of halogen lamps is much higher than that of ordinary incandescent lamps. Therefore, halogen lamps have a certain heat release effect and can be used as a heat source 30.

[0124] Among them, the microwave generator can convert electrical energy into microwave energy of rated frequency, thereby achieving a heat release effect.

[0125] The hot plate may be a heat source structure formed in a plate form by the above-mentioned infrared heat source, incandescent lamp, halogen tungsten lamp, microwave generator, or a resistance plate for generating heat when powered on to achieve the heat release function.

[0126] Specifically, the above-mentioned multiple types of heat sources 30 can facilitate users to select according to actual needs, which is conducive to selecting a suitable heat source according to actual needs, thereby reducing equipment costs or improving equipment performance, thereby improving market competitiveness.

[0127] In some embodiments, optionally, the temperature detection device 60 includes one or more of a thermocouple temperature sensor and a thermal resistor temperature sensor.

[0128] Thermocouple temperature sensors are used to directly measure temperature and convert the temperature signal into a thermoelectromotive force (EMF) signal, which is then converted to the temperature of the measured medium via an electrical instrument (secondary instrument). The basic principle of thermocouple temperature sensors is that two conductors of different compositions form a closed circuit. When a temperature gradient exists between the two ends, a current flows through the circuit, generating an electromotive force (EMF) between the two ends. This is known as the Seebeck effect.

[0129] A thermal resistor temperature sensor is a type of sensor thermometer that measures temperature based on the principle that the resistance of a conductor or semiconductor changes with temperature. Thermal resistor temperature sensors are categorized into two main types: metal thermistors and semiconductor thermistors. They are widely used to measure temperatures within the -200°C to +850°C range, with some applications allowing temperatures as low as 1K and as high as 1000°C. A thermal resistor sensor consists of a thermistor, connecting wires, and a display instrument. Thermistors can also be connected to temperature transmitters to convert temperature signals into standard current outputs.

[0130] Specifically, the different types of temperature detection devices 60 described above can facilitate users to select according to actual needs, thereby achieving the purpose of measuring the temperatures of different areas in the accommodating cavity 101.

[0131] In some embodiments, optionally, the cavity 10 further includes an air flow channel 102 communicating with the outside and the accommodating cavity 101 .

[0132] The air flow channel 102 is a channel for gas circulation, and can be used to connect external devices to achieve a corresponding cavity environment through the external devices.

[0133] For example, the external device can be a vacuum pump, used to evacuate the interior of the accommodating chamber 101 to achieve a vacuum environment. Vacuuming is the process of extracting and discharging gases from a specific space. The space is typically referred to as a vacuum when its pressure is less than one atmosphere relative to the atmosphere. The device used for vacuuming is called a vacuum pump, for example a vacuum pump.

[0134] Specifically, the cavity 10 in the drying device 100 provided in the present application also includes an air flow channel 102 for connecting the outside world and the accommodating cavity 101, so that when performing the drying operation, the corresponding cavity 10 environment can be achieved according to actual needs, for example, the accommodating cavity 101 is vacuumed to place the drying device 100 under vacuum conditions, which is beneficial to drying the object 200 to be dried.

[0135] Different from the prior art, the beneficial effect of the present application lies in that the drying equipment 100 provided by the present application includes a cavity 10, a heat source 30, a morphology detection device 40 and a control unit 50; wherein, the cavity 10 has a accommodating cavity 101, and the accommodating cavity 101 has an area to be dried; the heat source 30 and the morphology detection device 40 are arranged in the accommodating cavity 101, and when the object to be dried 200 is accommodated in the area to be dried, the morphology detection device 40 detects the film surface morphology of the object to be dried 200; the control unit 50 is respectively connected to the heat source 30 and the morphology detection device 40; the control unit 50 controls the working 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, so as to achieve uniform drying of the object to be dried 200. Furthermore, the drying equipment 100 also includes a temperature detection device 60 arranged in the accommodating chamber 101 and connected to the control unit 50, which is used to detect the temperature of different areas in the accommodating chamber 101 during the drying process, so that the control unit 50 adjusts the radiation intensity of the heat source 30 in a certain area based on the current temperature of the area detected by the temperature detection device 60, so that the temperature in the area is within a preset temperature range, thereby achieving the purpose of uniform drying.

[0136] Refer to Figure 8, which is a flow chart of an embodiment of a drying method for a drying device provided in the present application. Specifically, the present application also provides a drying method for a drying device 100, which is applied to the drying device 100 provided in any of the above embodiments, and the drying method includes:

[0137] Step S11 : obtaining the film surface morphology of the object to be dried 200 detected by the morphology detection device 40 .

[0138] Specifically, the control unit 50 is connected to the morphology detection device 40 ; when the object to be dried 200 is carried on the carrying device 20 , the control unit 50 obtains the film surface morphology of the object to be dried 200 detected by the morphology detection device 40 .

[0139] Step S12: controlling the working state of the heat source 30 based on the film surface morphology.

[0140] Specifically, the control unit 50 is also connected to the heat source 30; the control unit 50 controls the working 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 controlling the heat source 30 to form a targeted thermal field to achieve uniform drying of the object to be dried.

[0141] The number of heat sources 30 may be one or more, and the control unit 50 controls the working states of the multiple heat sources 30, including turning on and off some of the heat sources 30, adjusting the radiation intensity of the multiple heat sources 30, etc. The control unit 50 controls the working state of a heat source 30, controls the heat source 30 to move to a target position in the accommodating cavity 101, and adjusts the radiation intensity of the heat source 30, etc.

[0142] Specifically, the drying method can control the working state of the heat source 30 based on the film surface morphology of the object to be dried 200 contained in the drying area detected by the morphology detection device 40, which is beneficial to improving the drying uniformity of the object to be dried.

[0143] For the convenience of description, the following description will be made based on the case where there are multiple heat sources 30 .

[0144] In some embodiments, optionally, step S12 includes: obtaining membrane surface differentiation information based on the comparison of the membrane surface morphology with the stored standard uniformly dried membrane surface morphology; and adjusting the working state of the heat source 30 according to the membrane surface differentiation information.

[0145] Specifically, the control unit 50 can also pre-store the standard membrane surface morphology of the object to be dried 200 for uniform drying, and then compare it with the membrane surface morphology of the object to be dried 200 detected by the morphology detection device 40 to obtain the membrane surface difference information between the membrane surface morphology and the standard membrane surface morphology, thereby controlling the working status of multiple heat sources 30.

[0146] Specifically, by comparing the membrane surface morphology with a pre-stored standard membrane surface morphology, the membrane surface differentiation information is obtained, which is beneficial for targetedly controlling the multiple heat sources 30 to dry the object 200 to be dried, thereby improving the drying uniformity.

[0147] In some embodiments, optionally, adjusting the working state of the heat source according to the differential information of the film surface includes: adjusting the radiation intensity of the heat source 30 corresponding to different areas of the object to be dried 200 according to the differential information of the film surface.

[0148] The radiation intensity of the heat source 30 is positively correlated with the working power of the heat source 30 , that is, the greater the working power of the heat source 30 , the greater the radiation intensity, the higher the temperature generated by the released heat energy, and vice versa.

[0149] The heat source 30 that releases heat during operation and can cover a portion of the object 200 to be dried is the heat source 30 corresponding to that portion of the object 200 to be dried. The orthographic projections of the light-emitting surfaces of the heat sources 30 corresponding to different regions of the object 200 to be dried may completely overlap with those regions, for example, the heat source 30 may be located directly above or directly below those regions of the object 200 to be dried. The orthographic projections of the light-emitting surfaces of the heat sources 30 corresponding to different regions of the object 200 to be dried may also partially overlap with or not overlap with those regions, for example, the heat source 30 may be located diagonally above or diagonally below those regions of the object 200 to be dried. As long as the heat released by the heat source 30 during operation and can cover a portion of the object 200 to be dried, it is the heat source 30 corresponding to that region, and this is not limited to this.

[0150] In the present application, the control unit 50 adjusts the radiation intensity of the heat source 30 corresponding to different areas of the object to be dried 200 according to the film surface morphology detected by the morphology detection device 40, or the film surface differentiation information obtained through comparison, so as to dry different areas of the object to be dried 200 in a targeted manner based on the film surface morphology of different areas, thereby improving the drying uniformity of the object to be dried 200.

[0151] It is understandable that when the object to be dried 200 is dried, the drying conditions (such as temperature) may be different at different stages, or the degree of drying in different areas of the same object to be dried 200 may also be different. Therefore, the control unit 50 adjusts the radiation intensity of the heat source 30 corresponding to different areas of the object to be dried 200 according to the film surface morphology detected by the morphology detection device 40, or the film surface differentiation information obtained through comparison, thereby forming a targeted thermal field, so as to change the drying temperature of the object to be dried at different stages, or provide different drying temperatures for different areas of the same object to be dried 200, so as to improve the drying uniformity of the object to be dried 200.

[0152] In some embodiments, optionally, there are multiple heat sources 30; controlling the working state of the heat source 30 based on the membrane surface morphology includes: controlling the heat source 30 in the area corresponding to the object to be dried 200 to heat the object to be dried; and controlling the heat source 30 outside the area corresponding to the object to be dried 200 to stop working.

[0153] Specifically, the initial states of the multiple heat sources 30 can be all on, all off, or partially on and partially off. When the object 200 to be dried is carried on the carrying device 20, the topography detection device 40 detects the film surface topography of the object 200 to be dried, and the control unit 50 obtains the contour of the object 200 to be dried based on the film surface topography detected by the topography detection device 40.

[0154] If the initial states of the plurality of heat sources 30 are all turned on, the control unit 50 controls the heat sources 30 outside the area corresponding to the object 200 to be dried to stop working.

[0155] If the initial states of the plurality of heat sources 30 are all turned off, the control unit 50 controls the heat sources 30 in the areas corresponding to the objects to be dried 200 to operate so as to heat the objects to be dried 200 .

[0156] If the initial states of the multiple heat sources 30 can be partially open and partially closed, the control unit 50 controls the heat sources 30 in the area corresponding to the object 200 to work to heat the object 200 to be dried; and controls the heat sources 30 outside the area corresponding to the object 200 to stop working.

[0157] Specifically, the control unit 50 controls the heat source 30 in the area corresponding to the object to be dried 200 to work so as to dry the object to be dried 200; and controls the heat source 30 outside the area corresponding to the object to be dried 200 to stop working, thereby not only achieving targeted and uniform drying of the object to be dried, but also reducing the drying cost.

[0158] In some embodiments, optionally, step S11 includes: acquiring an image and / or contour of the object to be dried 200 detected by the shape detection device 40 .

[0159] Specifically, the image refers to the surface morphology of the object 200 to be dried, and can be a two-dimensional or three-dimensional image. For example, the image can reflect the dryness, in-surface texture, in-surface wrinkles, in-surface unevenness, etc. of the object 200 to be dried. A contour is the boundary or outline that constitutes any shape.

[0160] In the present application, the control unit 50 obtains the morphology and / or contour of the object to be dried 200 detected by the morphology detection device 40, so that the control unit 50 can judge the shape boundary and / or dryness degree of the object to be dried, thereby controlling the working status of multiple heat sources 30 in a targeted manner. For example, the control unit 50 controls the multiple heat sources 30 within the shape boundary of the object to be dried 200 to work based on the contour of the object to be dried 200, and controls the multiple heat sources 30 outside the shape boundary of the object to be dried not to work, so as to save drying costs; or the control unit 50 controls the working power of the heat sources 30 corresponding to different drying areas of the object to be dried 200 based on the morphology of the object to be dried 200, so as to form a targeted thermal field for areas with different dryness degrees, so as to facilitate uniform drying of the object to be dried 200.

[0161] In some embodiments, optionally, the drying method further includes: controlling the movement of the plurality of heat sources 30 in the accommodating cavity 101 based on the film surface morphology.

[0162] In the present application, a plurality of heat sources 30 are arranged to be movable within the accommodating chamber 101. The control unit 50 can control the movement of the plurality of heat sources 30 within the accommodating chamber 101 based on the membrane surface morphology of the object to be dried 200 detected by the morphology detection device 40, so as to adjust the positions of the plurality of heat sources 30 within the accommodating chamber 101 to achieve the optimal arrangement of the heat sources 30, and then control the working states of the plurality of heat sources 30, thereby controlling the heat sources 30 to form a targeted thermal field and achieve uniform drying of the object to be dried.

[0163] For example, the control unit 50 can control the movement of multiple heat sources 30 to form different distribution densities of heat sources 30 in different film surface areas based on the different sensitivities of different film surface areas, thereby correspondingly increasing or decreasing the drying rate in the corresponding areas. It is understood that a greater distribution density of heat sources 30 results in a higher drying rate, while a smaller distribution density of heat sources 30 results in a lower drying rate.

[0164] Alternatively, the control unit 50 may control the movement of the multiple heat sources 30 based on the image and / or outline of the object 200 to be dried so that the multiple heat sources 30 form a distribution pattern corresponding to the image and / or outline of the object 200 to be dried. For example, if the object 200 to be dried is circular, the control unit 50 controls the movement of the multiple heat sources 30 to form a corresponding circular drying area. Alternatively, if the object 200 to be dried is rectangular, the control unit 50 controls the movement of the multiple heat sources 30 to form a corresponding rectangular drying area.

[0165] Specifically, the control unit 50 controls the movement of the multiple heat sources 30 to change the arrangement density of the multiple heat sources 30 in different areas, and / or form a distribution pattern corresponding to the film surface morphology of the object to be dried, thereby facilitating uniform drying of the object to be dried 200.

[0166] Different from the prior art, the beneficial effect of the present application lies in that, in the drying method provided by the present application, the control unit 50 obtains the membrane surface morphology of the object to be dried 200 detected by the morphology detection device 40, and controls the working state of the heat source 30 based on the membrane surface morphology, such as turning on and off part of the heat source 30, adjusting the working power of the heat source 30, etc., so that a corresponding thermal field area is formed in the accommodating cavity 101, thereby achieving uniform drying of the object to be dried 200.

[0167] In a specific embodiment of the present application, the drying device 100 includes the above-mentioned chamber 10, a carrying device 20, multiple heat sources 30, a shape detection device 40, a temperature detection device 60, and a control unit 50. Referring to FIG9 , FIG9 is a drying logic diagram of the drying device provided in an embodiment of the present application. The drying logic of the drying device 100 includes:

[0168] Step S21: Place the object to be dried on the carrying device, close the accommodating chamber and evacuate the chamber.

[0169] Step S22: The morphology detection device detects the real-time film surface morphology of the object to be dried.

[0170] Step S23: The control unit compares the real-time membrane surface morphology with the stored uniformly dried standard membrane surface morphology to obtain local membrane surface differentiation information.

[0171] Step S24: The control unit controls the heat source in the area corresponding to the object to be dried to operate based on the local film surface differentiation information to dry the object to be dried carried on the carrying device, and controls the heat source outside the area corresponding to the object to be dried to not operate.

[0172] Step S25: The temperature detection device detects the temperature in the accommodating cavity.

[0173] Step S26: The control unit obtains a preset temperature range corresponding to a certain area of ​​the object to be dried, and adjusts the working power of the heat source in the certain area based on the current temperature of the certain area detected by the temperature detection device, so that the temperature in the certain area is within the preset temperature range, thereby achieving adjustment of the drying speed of the certain area.

[0174] Step S27: Based on the uniformly dried standard film surface morphology detected by the morphology detection device, the vacuum of the accommodating cavity is broken, and the uniformly dried object to be dried is taken out.
