[0061] See also Figure 1 As shown, in some embodiments of the present application, this embodiment provides an oven device for LED packaging, including:

[0062] Outer shell 100;

[0063] A baking chamber 110 is located inside the outer shell 100. The baking chamber 110 is used to dry the LED packaging material. An observation window is provided on the side of the baking chamber 110.

[0064] The drying components are arranged at intervals along the circumferential direction of the baking chamber 110;

[0065] An air inlet assembly is located on the side of the baking chamber 110 and close to the bottom of the baking chamber 110, and the air inlet assembly is connected to the drying assembly;

[0066] The heat-insulating layer 140 is located between the outer shell 100 and the baking chamber 110, and two sides of the heat-insulating layer 140 are connected to the outer shell 100 and the baking chamber 110;

[0067] There are several image sensors, located at positions corresponding to the observation window on the thermal insulation layer 140, and the image sensors are evenly arranged in sequence from top to bottom along the vertical direction, and the image sensors are used to capture image data in the observation window;

[0068] A support component is located inside the baking cavity 110 and is used to hold LED packaging materials;

[0069] There are several temperature sensors, which are respectively located inside the baking chamber 110 and on the drying component;

[0070] The control device is used to control the drying temperature and time of the drying component. The control device is also used to control the air intake rate of the air intake component.

[0071] It can be seen that the outer shell 100 is the protective structure of the entire oven equipment, which is used to protect the structure inside the outer shell 100, ensuring the stability of the internal environment of the entire equipment and the stable operation of the entire equipment; the baking chamber 110 provides a drying space for the LED packaging material, ensuring the smooth progress of the drying process; the drying component is responsible for providing the heat required for drying to ensure that the LED packaging material can be evenly heated; the air intake component is responsible for adjusting the airflow in the baking chamber 110 to ensure the temperature and humidity control during the drying process; the insulation layer 140 effectively isolates the influence of the external temperature on the baking chamber 110 and maintains a constant temperature environment in the baking chamber 110; the image sensor is used to monitor the drying state of the LED packaging material in real time and provide accurate data support for the control device; the support component provides a stable placement platform for the LED packaging material to ensure the uniformity of the drying process; the temperature sensor is used to monitor the temperature in the baking chamber 110 in real time and provide temperature feedback for the control device; the control device is used to integrate the operating status of each component to achieve accurate control of the entire drying process. By real-time monitoring and adjusting the drying temperature, time and air intake rate, the control device can ensure that the LED packaging material is dried under the best conditions, thereby improving the packaging quality and production efficiency.

[0072] Specifically, the drying components include:

[0073] The first heating plates 121 are arranged at intervals along the circumferential direction of the baking chamber 110, and the first heating plates 121 are located on the inner wall of the baking chamber 110;

[0074] The second heating plate 122 is located on the inner bottom wall and the inner top wall of the baking chamber 110;

[0075] Air inlet holes 123 : The side walls of the baking chamber 110 are evenly provided with air inlet holes 123 , and the air inlet holes 123 are spaced apart from the first heating plate 121 .

[0076] It can be seen that the drying assembly includes a first heating plate 121 and a second heating plate 122, which can quickly increase the ambient temperature inside the drying chamber, and ensure temperature uniformity through evenly distributed heating plates, so that the LED packaging material can obtain uniform heat supply during the drying process; the first heating plate 121 is located on the inner wall of the baking chamber 110, ensuring that heat can be evenly transferred to the LED packaging material from all directions; the second heating plate 122 is located on the inner bottom wall and the inner top wall of the baking chamber 110, further enhancing the heating effect of the bottom and top, avoiding temperature gradients during the drying process, and ensuring the uniformity of the drying effect; the uniform opening of the air inlet holes 123 helps to adjust the air flow distribution in the baking chamber 110, so that the hot air can flow more evenly, thereby improving the drying efficiency; the air inlet holes 123 are spaced apart from the first heating plate 121, which can prevent hot air from blowing directly to the heating plate, thereby extending the service life of the heating plate.

[0077] Specifically, the air inlet components include:

[0078] The air inlet device 131 is located on the side of the baking cavity 110 and close to the bottom of the baking cavity 110;

[0079] There are several air inlet nozzles, and the several air inlet nozzles are located at the air inlet end of the air inlet device 131, and an air inlet valve is arranged inside the air inlet nozzle;

[0080] The air outlet nozzles include a plurality of air outlet nozzles, and the plurality of air outlet nozzles are connected to the air inlet hole 123 .

[0081] It can be seen that the air inlet assembly ensures the uniform distribution of airflow in the baking chamber 110, and realizes precise control of the drying process of the LED packaging material; the air inlet device 131 is located on the side of the baking chamber 110 and close to the bottom, which helps to introduce normal temperature air from the bottom and evenly deliver it into the baking chamber 110 through the air inlet nozzle; the air inlet valve arranged inside the air inlet nozzle can adjust the amount of air entering the baking chamber 110, ensuring the stability of temperature and humidity during the drying process; the air outlet nozzle is connected to the air inlet hole 123, so that normal temperature air can enter through the air inlet hole 123, thereby forming a uniform airflow distribution in the baking chamber 110, further improving the drying efficiency.

[0082] It is understandable that a ventilation hole is also provided on the top of the baking chamber 110, which can be opened when needed and closed when not needed.

[0083] Specifically, the support components include:

[0084] The rotating shaft 151 is vertically arranged inside the baking chamber 110, one end of the rotating shaft 151 passes through the bottom of the baking chamber 110 and is connected to the output end of the driving motor, and the other end of the rotating shaft 151 faces the inner top wall of the baking chamber 110;

[0085] A plurality of connecting rods 152 are evenly arranged in a spiral shape from top to bottom along the circumferential direction of the rotating shaft 151, and one end of the connecting rod 152 is connected to the rotating shaft 151;

[0086] The support plate 153 is connected to the other end of the connecting rod 152 , and is used for holding LED packaging materials.

[0087] It can be seen that the design of the support assembly enables the LED packaging material to be heated evenly during the drying process, while ensuring the stability and uniformity of the material; the rotating shaft 151 can enable the support plate 153 to rotate in the baking chamber 110, thereby avoiding the problems of uneven temperature and uneven heating of the material that may occur during the drying process; the spiral uniform setting of the connecting rod 152 ensures that the support plate 153 can remain stable during the rotation process, avoiding the influence of vibration caused by the rotation on the drying effect; the support plate 153 is connected to the connecting rod 152, so that the LED packaging material can be evenly distributed on the support plate 153, thereby achieving the purpose of uniform drying.

[0088] Specifically, the control device includes:

[0089] The acquisition unit is configured to acquire first image data of the observation window through an image sensor, acquire the drying degree of the LED packaging material according to the first image data, and determine whether to turn on the air inlet device 131 according to the drying degree; when the acquisition unit determines to turn on the air inlet device 131, the acquisition unit is further configured to acquire temperature data inside the baking chamber 110, and determine whether to heat the air charged into the baking chamber 110 according to the temperature data;

[0090] The adjustment unit is configured to collect second image data of the observation window after the air inlet component runs for a first preset time after determining whether to heat the air charged into the baking chamber 110, obtain a change rate of the drying degree according to the second image data and the first image data, and determine whether to adjust the air inlet rate according to the change rate;

[0091] a judgment unit configured to collect third image data of the observation window after determining whether to adjust the air intake rate and when a second preset time is satisfied, and judge whether the drying is complete according to the third image data;

[0092] If the judging unit determines that the drying is complete, a command to stop drying is issued to control the drying component and the air inlet component to stop working.

[0093] It can be seen that the control device realizes precise control of the drying process of the LED packaging material through the coordinated work of the acquisition unit, the adjustment unit and the judgment unit; the acquisition unit monitors the drying state in real time through the image sensor, obtains the drying degree of the LED packaging material, and judges whether it is necessary to turn on the air inlet device 131 according to the drying degree. When it is judged that the air inlet device 131 needs to be turned on, the acquisition unit will also collect the temperature data inside the baking chamber 110 to judge whether it is necessary to heat the air charged into the baking chamber 110; after judging whether to heat the air charged into the baking chamber 110, the adjustment unit will run the air inlet component for a period of time. Then, the second image data of the observation window is collected. According to the drying degree change rate obtained from the second image data and the first image data, the adjustment unit can determine whether the air intake rate needs to be adjusted to ensure the uniformity and efficiency of the drying process. After determining whether to adjust the air intake rate, the judgment unit will collect the third image data of the observation window after a period of time. According to the third image data, the judgment unit can determine whether the LED packaging material has been completely dried. If the judgment unit determines that it has been completely dried, it will issue an instruction to stop drying and control the drying component and the air intake component to stop working, thereby ensuring that the LED packaging material completes the drying process under optimal conditions.

[0094] It is understandable that through this precise control, the drying quality and production efficiency of LED packaging materials can be effectively improved, while reducing energy consumption and production costs; the design of the entire drying system fully considers the temperature, humidity, air flow distribution and time control during the drying process, ensuring the stability and reliability of the drying process. By real-time monitoring and adjustment of drying parameters, defects and problems in the drying process can be effectively avoided, thereby improving the overall performance and service life of LED packaging materials.

[0095] Specifically, the acquisition unit acquires the first image data of the observation window through the image sensor, acquires the drying degree of the LED packaging material according to the first image data, and determines whether to open the air inlet device 131 according to the drying degree, including:

[0096] Analyze image data through image recognition algorithms to identify the surface features of LED packaging materials to determine their drying degree;

[0097] Preset a drying degree threshold, compare the drying degree with the drying degree threshold, and determine whether to open the air inlet device 131 according to the comparison result;

[0098] When the drying degree does not reach the drying degree threshold, the air inlet device 131 is not turned on;

[0099] If the drying degree has reached or exceeded the drying degree threshold, the air inlet device 131 is started.

[0100] It can be seen that the acquisition unit analyzes the surface features of the LED packaging material through the image recognition algorithm and can accurately determine the drying degree of the material. The image recognition algorithm can identify subtle changes on the surface of the material, thereby accurately reflecting the actual state of the drying process; by setting the drying degree threshold, the system can automatically determine whether it is necessary to turn on the air inlet device 131, thereby realizing automatic control of the drying process; when the drying degree does not reach the threshold, the system will not turn on the air inlet device 131 to avoid unnecessary impact on the LED packaging material. When the drying degree reaches or exceeds the threshold, the system will automatically start the air inlet device 131 and introduce an appropriate amount of room temperature air to ensure the smooth progress of the drying process. This precise control method not only improves the drying efficiency, but also ensures the quality of the LED packaging material.

[0101] Specifically, when the acquisition unit determines to turn on the air inlet device 131, the acquisition unit collects temperature data inside the baking chamber 110, and determines whether to heat the air charged into the baking chamber 110 according to the temperature data, including:

[0102] The acquisition unit compares the temperature data with a preset temperature data threshold, and determines whether to heat the air charged into the baking chamber 110 according to the comparison result;

[0103] Under the first temperature comparison result, the acquisition unit determines to heat the air charged into the baking chamber 110;

[0104] Under the second temperature comparison result, the acquisition unit determines not to heat the air charged into the baking chamber 110;

[0105] The first temperature comparison result is that the temperature data is less than the temperature data threshold, and the second temperature comparison result is that the temperature data is greater than or equal to the temperature data threshold.

[0106] It is understandable that the acquisition unit ensures that the temperature of the drying process is controlled within a reasonable range by real-time monitoring the temperature inside the baking chamber 110. When the temperature data is lower than the preset temperature threshold, it indicates that the temperature inside the baking chamber 110 is low, and the charged air needs to be heated to maintain the temperature conditions required for drying; if the temperature data is higher than or equal to the preset temperature threshold, it indicates that the temperature inside the baking chamber 110 is sufficient and no additional heating is required. In this case, the acquisition unit will determine not to heat the charged air to avoid excessive temperature causing damage to the LED packaging material or over-drying; through real-time monitoring and comparison of such temperature data, the control device can flexibly adjust the heating strategy to ensure that the temperature of the drying process is always in the best state, which not only improves the drying efficiency, but also ensures the quality and performance of the LED packaging material.

[0107] Specifically, when heating the air charged into the baking chamber 110, the steps include:

[0108] The acquisition unit acquires a temperature difference between the temperature data and a temperature data threshold;

[0109] The heating power of the wind that the air inlet device 131 controls to be filled into the baking chamber 110 is positively correlated with the temperature difference.

[0110] It is understandable that when it is necessary to heat the air charged into the baking chamber 110, the acquisition unit will adjust the heating power according to the temperature difference to ensure that the temperature of the drying process is controlled within the optimal range. The acquisition unit first calculates the difference between the temperature data and the temperature data threshold, which reflects the difference between the current temperature inside the baking chamber 110 and the set target temperature; if the difference is large, it means that the temperature inside the baking chamber 110 is low and more heat is needed to increase the temperature; on the contrary, if the difference is small, it means that the temperature inside the baking chamber 110 is close to the target temperature and the heating power can be appropriately reduced; according to this temperature difference, the acquisition unit will control the heating power of the air inlet device 131 so that it is positively correlated with the temperature difference, which means that the larger the temperature difference, the higher the heating power, and the smaller the temperature difference, the lower the heating power. By dynamically adjusting the heating power, it can be ensured that the temperature inside the baking chamber 110 is always stable near the set target temperature, thereby achieving precise control of the LED packaging material drying process.

[0111] Specifically, obtaining the change rate of the drying degree according to the second image data and the first image data, and determining whether to adjust the air intake rate according to the change rate, includes:

[0112] The change rate is compared with a preset change rate threshold, and whether the air inlet rate is adjusted is determined according to the comparison result;

[0113] When the change rate is less than the change rate threshold, the air inlet rate is not adjusted;

[0114] When the change rate is greater than or equal to the change rate threshold, the air intake rate is adjusted, and the air intake rate is inversely proportional to the change rate.

[0115] It is understandable that the acquisition unit can detect abnormal conditions in the drying process and make corresponding adjustments in real time by monitoring the rate of change of the drying degree of the LED packaging material. When the rate of change is lower than the preset rate of change threshold, it indicates that the drying process is proceeding normally and there is no need to adjust the air intake rate; and when the rate of change is higher than or equal to the preset rate of change threshold, it indicates that the drying process may be too fast or too slow and the air intake rate needs to be adjusted to ensure the drying effect.

[0116] Specifically, after determining whether to adjust the air intake rate, the judging unit collects the third image data of the observation window after the second preset time, and judges whether the drying is complete according to the third image data, including:

[0117] The judging unit acquires the final drying degree of the LED packaging material according to the third image data;

[0118] The judgment unit compares the final drying degree with a preset complete drying threshold;

[0119] If the final drying degree reaches or exceeds the complete drying threshold, it is determined that the LED packaging material is completely dried;

[0120] If the final drying degree does not reach the complete drying threshold, it is determined that the LED packaging material is not completely dried.

[0121] It can be seen that in the final stage of the drying process, the judgment unit evaluates the final drying degree of the LED packaging material by collecting the third image data of the observation window. This process ensures the accuracy and reliability of the drying process and avoids material quality problems caused by incomplete drying.

[0122] It is understandable that the judgment unit first obtains the final drying degree of the LED packaging material based on the third image data. Through the image recognition algorithm, the judgment unit can identify subtle changes on the surface of the material, thereby accurately reflecting the actual state of the drying process. Next, the judgment unit compares the final drying degree with the pre-set complete drying threshold to determine whether the drying has achieved the expected effect. If the final drying degree reaches or exceeds the complete drying threshold, the judgment unit determines that the LED packaging material is completely dried, which means that the material has reached the expected goal of the drying process and can proceed to the next step of packaging or packaging; on the contrary, if the final drying degree does not reach the complete drying threshold, the judgment unit determines that the LED packaging material is not completely dried and requires further drying treatment.

[0123] In summary, the oven equipment for LED packaging provided in this embodiment can achieve precise control of the drying process of LED packaging materials, thereby improving the drying efficiency and material quality; by real-time monitoring of the temperature inside the baking chamber 110, the temperature is ensured to be controlled within a reasonable range, thereby avoiding damage to the LED packaging materials caused by excessively high or low temperatures; by adjusting the heating power to be positively correlated with the temperature difference, dynamic adjustment of the drying process is achieved, thereby ensuring that the temperature is always stable near the set target temperature.
