The production process of skylights involves curing resin-impregnated glass fibers in an oven to form a panel structure. Existing publication number CN102037871A discloses an anti-fogging polycarbonate sheet, comprising a polycarbonate sheet body with a hollow structure, characterized in that an anti-fogging layer to prevent condensation is provided on the surface of the polycarbonate sheet body. A method for preparing the anti-fogging polycarbonate sheet is as follows: PC material is melt-extruded into a mold at a high temperature of 265℃~285℃ using an extruder; then cooled and shaped at 40℃~90℃ using a sizing device; annealed at 110℃~125℃ for 1~5 minutes; coated with an anti-fogging agent; and dried at 80℃~100℃ for 1~3 minutes. The anti-fogging layer on the surface of the polycarbonate sheet body solves the fogging problem present in existing hollow polycarbonate sheets. The process is simple and easy to operate. In the process of realizing this application, the inventors discovered the following problems with the prior art: In existing multi-segment molding processes for daylighting panels, there are issues with light transmittance defects caused by excessive length and uneven local temperatures.

This can easily cause localized overcooling or overheating of the daylighting panel, resulting in problems such as fluctuations in light transmittance and inconsistent molding. Therefore, an intelligent temperature control system for multi-segment molding of light-transmitting panels is proposed to address the above problems. Summary of the Invention

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example 1 As attached Figures 1 to 12The intelligent temperature control system for multi-segment molding of light-transmitting panels shown includes a light-transmitting panel production line 1, a heating box 10, and a defect handling box 11. The light-transmitting panel production line 1 includes a light-transmitting panel assembly structure 42. A first conveyor 8 is placed below the light-transmitting panel assembly structure 42. The heating box 10 is placed on one side of the light-transmitting panel body 14 assembly structure on the first conveyor 8. The defect handling box 11 is placed on the side of the heating box 10. A curing box 12 is placed on the side of the defect handling box 11. A trimming box 13 is placed on the side of the curing box 12. A controller 15 is placed on the side of the trimming box 13. The light-transmitting panel body 14 is placed above the first conveyor 8. The temperature inside the heating chamber 10 and the temperature of the light-transmitting panel body 14 are monitored in real time. Based on the light transmittance test results of the light-transmitting panel body 14, the light transmission defects caused by abnormal temperature are determined, and the defective parts are repaired by cutting, pressurizing and micro-vibration. At the same time, the temperature closed-loop correction of the heating chamber 10 is performed.

[0021] During the production of the light-transmitting panel body 14, after the light-transmitting panel body 14 enters the heating chamber 10, due to the length of the heating chamber 10 itself, temperature changes are prone to occur in some areas during operation, causing problems with the light transmittance of the light-transmitting panel body 14 in those areas. Therefore, the material of the light-transmitting panel body 14 is processed by the light-transmitting panel assembly mechanism 42 and sent into the heating chamber 10. Then, the heating chamber 10 heat-treats the light-transmitting panel body 14 inside. The first temperature monitoring platform 31 inside the heating chamber 10 monitors the heating platform 34 by moving it periodically to confirm the temperature changes inside the heating chamber 10, instead of using a fixed-point temperature probe to confirm the ambient temperature. Then, the light-transmitting panel temperature monitoring component 37 monitors the temperature of the light-transmitting panel body 14 itself by moving it periodically to confirm the heating temperature inside the heating chamber 10. In case of temperature changes... When the light transmittance of the main body 14 of the light-transmitting panel is detected by the defect handling box 11, the first temperature monitoring platform 31 and the temperature monitoring component 37 of the light-transmitting panel begin to move to confirm the location of the temperature change. The temperature change at the location is monitored in real time. Then, the inclined cutting machine 17 in the defect handling box 11 cuts the light-transmittance problem of the main body 14 of the light-transmitting panel. The rear light-transmitting panel 14 continues to move, contacts the front light-transmitting panel 14 and pushes the front light-transmitting panel 14 to continue moving. When it moves into the heating and pressing box 18, the heating and pressing box 18 aligns the divided light-transmitting panel 14 and heats the surrounding temperature to make the temperature consistent, allowing the two sets of light-transmitting panel 14 to re-fuse. Then, the fused and connected light-transmitting panel 14 enters the micro-vibration pressure box 19, where ultrasonic vibration is applied to the gaps to allow the molecules between the gaps of the light-transmitting panel 14 to complete molecular interpenetration, thereby solving the light transmittance problem of the seam and completing the repair of the light transmittance problem.

[0030] As a preferred embodiment, an intelligent temperature control system for multi-segment molding of light-transmitting panels is provided, wherein the intelligent temperature control system executes the following temperature control and defect repair algorithm: The temperature deviation of heating chamber 10 meets the following requirements: ; The set temperature of the heating platform 34; Real-time temperature monitoring of heating platform 34; Temperature deviation of heating chamber 10; Temperature deviation of the main body 14 of the light-transmitting panel meets the following requirements: ; : The set process temperature of the main body 14 of the light-transmitting panel; Real-time monitoring temperature of the main body 14 of the light-transmitting panel; Temperature deviation of the main body 14 of the light-transmitting panel; The overall temperature anomaly indicators meet the following requirements: ; when At that time, the system determined that the temperature was abnormal; Weighting coefficients; Temperature anomaly threshold; Comprehensive temperature anomaly indicators; Transmittance deviation satisfies: ; Standard light transmittance; Measured transmittance; Transmittance deviation; when When this happens, the system determines that the light transmittance is abnormal; : Permissible deviation threshold for light transmittance; When both temperature anomaly and light transmittance anomaly are met simultaneously, the system determines that the light transmittance defect is caused by the temperature anomaly; the system determines the cutting coordinates based on the defect location. ; Location for detecting light transmission defects; The moving speed of the main body 14 of the light-transmitting panel; System response delay; : Actual laser cutting location; And output repair pressure; ; Basic repair pressure; Pressure regulation coefficient; Actual output repair pressure; And the frequency of micro-vibrations; ; : Basic vibration frequency; Frequency adjustment coefficient; Actual output vibration frequency; Repair the defective areas of the main body 14 of the light-transmitting panel; At the same time, the temperature control system performs closed-loop temperature compensation; ; Temperature compensation coefficient; : Transmittance feedback compensation coefficient; The final output temperature of the heating platform 34; Achieve adaptive correction of heating temperature.

[0031] The working process of this application is as follows: First, during the production of the light-transmitting panel body 14, after the light-transmitting panel body 14 enters the heating box 10, due to the influence of the length of the heating box 10, local temperature fluctuations are likely to occur during continuous operation, which in turn leads to abnormal light transmittance of the light-transmitting panel body 14 in the area. Therefore, this system completes the composite and molding process of the raw materials of the light-transmitting panel body 14 through the light-transmitting panel assembly mechanism 42, and then sends the molded light-transmitting panel body 14 into the heating box 10 for heat treatment; the first temperature monitoring platform 31 in the heating box 10 adopts a timed movement method to monitor the temperature of the heating platform 34 throughout the entire area, rather than relying solely on a fixed-point temperature probe to detect the local ambient temperature. At the same time, the light-transmitting panel temperature monitoring component 37 moves to measure the temperature of the light-transmitting panel body 14 itself, and obtains the actual heated temperature of the light-transmitting panel body 14 in real time, thereby providing feedback on the true temperature distribution inside the heating box 10. When abnormal temperature changes cause light transmittance defects in the main body 14 of the light-transmitting panel, the light transmittance detection mechanism in the defect handling box 11 can promptly identify the defect location. At this time, the first temperature monitoring platform 31 and the light-transmitting panel temperature monitoring component 37 move synchronously to determine the specific area where the temperature anomaly occurs, thus tracing the source of the temperature anomaly. Subsequently, the inclined cutting machine 17 in the defect handling box 11 cuts the part of the main body 14 of the light-transmittance panel with the light transmittance defect, removing the defective section. The continuously conveyed main body 14 of the light-transmitting panel continues to move forward, contacting the end of the cut main body 14 of the light-transmitting panel and pushing it forward synchronously. When the two sections of the main body 14 of the light-transmitting panel are... After entering the heating and extrusion chamber 18, the heating and extrusion chamber 18 aligns and positions the two sections of the light-transmitting panel body 14, and provides auxiliary heating to the cut end face and surrounding area to make the end face temperature more uniform, providing temperature conditions for the re-fusion of the two sections of the light-transmitting panel body 14. After the light-transmitting panel body 14 has been heated and aligned, it continues to enter the micro-vibration pressure chamber 19. Through the action of ultrasonic micro-vibration, the molecules on the cut end face of the two sections of the light-transmitting panel body 14 produce a molecular interpenetration effect. Under the combined action of pressure and vibration, a seamless joint is achieved, eliminating the problem of uneven light transmittance at the joint, completing the online remedy for light transmittance defects, and ensuring the overall forming quality of the light-transmitting panel body 14.
