[0002] This disclosure relates to a temperature control device and a welding light box. Background Technology

[0003] In the production of photovoltaic cells, multiple cells need to be connected in series using welding ribbons. During welding, the welding ribbons and cells are placed on a welding platform under a welding lamp box. Under the high temperature generated by the lamp box and the action of flux, they react and are welded together.

[0004] During the welding process, a large amount of heat is generated inside the welding lamp box. If heat cannot be effectively dissipated, it will not only affect the welding quality but also pose a safety hazard to the operators. Traditional heat dissipation methods mostly use fixed ventilation designs, which cannot be flexibly adjusted according to the actual temperature changes inside the welding lamp box, resulting in poor heat dissipation.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0033] This disclosure provides a temperature control device that can be used inside a welding lamp box.

[0034] As shown in Figures 1 to 3, the temperature control device provided in this disclosure includes:

[0035] The system comprises an adjustment unit 1, a control unit, and a sensing unit 2. The adjustment unit 1 is located inside the ventilation duct 100 of the welding lamp box. The sensing unit 2 and the control unit are respectively located inside the welding lamp box. The adjustment unit 1 and the sensing unit 2 are respectively connected to the control unit. The sensing unit 2 can detect the real-time temperature inside the welding lamp box, so that the control unit can control the adjustment unit 1 to adjust the air intake of the ventilation duct 100.

[0036] Specifically, the regulating unit 1 is typically installed inside the ventilation duct 100 of the welding light box's air outlet structure. For example, the regulating unit 1 can be an adjustable valve, a moving stop, etc., used to adjust the air intake volume inside the ventilation duct 100 according to control commands. The air outlet structure of the welding light box includes, but is not limited to, air conditioners and fans.

[0037] The control unit can be located inside or near the welding lamp box. It can be a central processing unit (CPU) or a microcontroller (MCU) or other intelligent control unit, responsible for receiving signals detected by the sensor unit 2, analyzing and processing them, and issuing adjustment commands. The sensor unit 2 can be located inside the welding lamp box. It can be a high-precision temperature sensor, such as a thermistor, thermocouple, or digital temperature sensor, used to detect the temperature inside the welding lamp box in real time.

[0038] In this way, sensor 2 can continuously monitor the temperature inside the welding lamp box and transmit the temperature data to the control unit via wired or wireless means. After receiving the temperature data, the control unit compares it with a preset temperature range. If the actual temperature exceeds the preset range, the control unit calculates the required airflow adjustment and controls the regulating unit 1 to make the adjustment. If the temperature is too high, the airflow is increased to enhance heat dissipation; if the temperature is too low, the airflow is reduced to prevent overcooling.

[0039] The regulating unit 1 can be an electrically adjustable damper, which is driven by a stepper motor to open at an angle, thereby achieving precise control of the air intake. The control unit can be a microcontroller with a built-in PID control algorithm, which automatically adjusts the opening of the electrically adjustable damper according to the temperature deviation, ensuring that the temperature can quickly stabilize to the preset range.

[0040] The ventilation duct 100 can be designed to be detachable, facilitating the installation and maintenance of the adjustment unit 1. Additionally, a dustproof screen can be installed inside the ventilation duct 100 to prevent external impurities from entering the welding light box.

[0041] Therefore, based on the real-time temperature data transmitted by the sensor unit 2, the control unit can intelligently adjust the working state of the regulating unit 1 through a built-in control algorithm, thereby achieving precise adjustment of the air intake of the ventilation duct 100. This intelligent adjustment method can quickly respond to temperature changes, ensuring that the internal temperature of the welding lamp box remains within a preset range, avoiding a decline in welding quality due to excessively high or low temperatures. Furthermore, a stable temperature environment also helps to improve the strength and reliability of the welded joint, thereby improving the welding quality.

[0042] Furthermore, excessively high temperatures during welding can lead to safety accidents such as fires or burns. The temperature control device provided in this disclosure can monitor and control the temperature inside the welding lamp box in real time, effectively reducing these safety risks and providing operators with a safer working environment.

[0043] Furthermore, by precisely adjusting the air intake of the ventilation duct 100 through the adjustment unit 1, the temperature control device provided in this disclosure can adjust the heat dissipation according to actual needs, avoiding unnecessary energy waste and helping to reduce the operating costs of welding equipment, while also conforming to environmental protection principles. Moreover, by controlling the temperature inside the welding lamp box, the generation and emission of pollutants such as exhaust gas and fumes during the welding process can be reduced, contributing to environmental protection.

[0044] Optionally, the regulating unit 1 includes a regulating valve, and the control unit is capable of controlling the regulating valve to adjust the valve opening.

[0045] Specifically, the regulating unit 1 may include regulating valves such as butterfly valves and ball valves. Based on the temperature data transmitted by the sensing unit 2, the control unit can intelligently adjust the valve opening of the regulating valve through a built-in control algorithm, thereby adjusting the air intake of the ventilation duct 100 to ensure that the internal temperature of the welding lamp box is maintained within a preset range, thus avoiding a decrease in welding quality due to excessively high or low temperatures.

[0046] Optionally, the adjustment unit 1 includes an adjustment block, one end of which is connected to the inner wall of the ventilation duct 100 of the welding light box. The control unit can control the movement of the adjustment block to adjust the air intake of the ventilation duct 100.

[0047] Specifically, an adjusting block can be provided, with one end of the adjusting block fixedly connected to the inner wall of the ventilation duct 100 of the welding lamp box, and the adjusting block can rotate along this fixed end. During the rotation of the adjusting block, it can shield and avoid the air intake of the ventilation duct 100, thereby adjusting the air intake of the ventilation duct 100 to ensure that the internal temperature of the welding lamp box is maintained within a preset range, avoiding a decrease in welding quality due to excessively high or low temperatures.

[0048] In another embodiment, an adjusting block can be provided that extends and retracts along the inner wall of the ventilation duct 100 of the welding lamp box, with the extension and retraction direction of the adjusting block perpendicular to the air intake direction. When the adjusting block extends, it can shield the air intake of the ventilation duct 100; when the adjusting block retracts, it can avoid the air intake of the ventilation duct 100, and can also adjust the air intake of the ventilation duct 100 to ensure that the internal temperature of the welding lamp box is maintained within a preset range, avoiding a decrease in welding quality due to excessively high or low temperatures.

[0049] Optionally, during the movement of the adjusting block, the shielding area of ​​the adjusting block on the ventilation duct 100 changes.

[0050] Specifically, when the adjusting block is rotated to the shielding position, its shielding area on the ventilation duct 100 is at its maximum; when the adjusting block is rotated to the clearance position, its shielding area on the ventilation duct 100 is at its minimum. Alternatively, when the adjusting block is moved to the extended position, its shielding area on the ventilation duct 100 is at its maximum; when the adjusting block is moved to the retracted position, its shielding area on the ventilation duct 100 is at its minimum. In this way, the air intake of the ventilation duct 100 can be adjusted to ensure that the internal temperature of the welding lamp box is maintained within a preset range, avoiding a decrease in welding quality due to excessively high or low temperatures.

[0051] Optionally, the adjustment unit 1 includes a driving member 11 and an adjustment member 12. The driving end of the driving member 11 is connected to the adjustment member 12. Under the drive of the driving member 11, the adjustment member 12 can adjust the air intake of the ventilation duct 100.

[0052] As shown in Figure 3, the driving component 11 can drive the adjusting component 12 to adjust the air intake of the ventilation duct 100, thereby ensuring that the internal temperature of the welding lamp box is maintained within a preset range and avoiding a decrease in welding quality due to excessively high or low temperatures. The driving component 1 includes, but is not limited to, a servo motor and a reducer.

[0053] Optionally, the welding light box is equipped with a fan 200 and a fan controller. The control unit is used for communication connection with the fan controller, and the control unit can control the fan controller to adjust the speed of the fan 200.

[0054] Specifically, based on the temperature data transmitted by the sensor unit 2, the control unit can intelligently adjust the speed of the fan 200 via the fan controller through a built-in control algorithm. For example, when the temperature is high, the speed of the fan 200 is increased; when the temperature is low, the speed of the fan 200 is decreased. In this way, the fan 200 can work in conjunction with the adjustment unit 1 to adjust the air intake of the ventilation duct 100, thereby ensuring that the internal temperature of the welding lamp box is kept stable within a preset range, avoiding a decrease in welding quality due to excessively high or low temperatures.

[0055] Optionally, the ventilation duct 100 includes an air outlet duct, and the adjusting part 1 is located on the air outlet duct. In this way, the airflow directed towards the lamp tube 300 can be adjusted using the adjusting part 1, thereby ensuring that the internal temperature of the welding lamp box remains within a preset range, avoiding a decrease in welding quality due to excessively high or low temperatures.

[0056] Optionally, the ventilation duct 100 further includes two air inlet pipes, one end of each air inlet pipe being connected to a fan 200, and the other end of each air inlet pipe being connected to the air outlet pipe.

[0057] Specifically, the ventilation duct 100 can be a three-way duct, which includes two exhaust ducts and one blower duct. The exhaust ducts are also known as air inlets, and the blower duct is also known as air outlets. Each air inlet duct is connected to a fan 200 to collect the air blown out by the fan 200 and blow it to the lamp tube 300 through the air outlet duct, thereby enabling flexible adjustment of the internal temperature of the welding lamp box.

[0058] Optionally, the sensing unit 2 includes at least one temperature sensor.

[0059] Specifically, the sensing unit 2 can employ a high-precision temperature sensor, capable of detecting temperature changes inside the welding lamp box in real time and accurately, providing reliable data support to the control unit, thus making temperature control more precise. One, two, or even multiple temperature sensors can be used to enhance the reliability of temperature detection. Multiple temperature sensors can also serve as backups for each other, preventing sensor failure due to a single sensor malfunction.

[0060] In addition, the sensing unit 2 can be equipped with a humidity sensor. The humidity sensor and the temperature sensor work together to provide the control unit with more comprehensive environmental parameters and achieve more precise temperature and humidity control.

[0061] This disclosure also provides a welding light box, including the aforementioned temperature control device.

[0062] The control unit, based on real-time temperature data transmitted from the sensor unit 2, intelligently adjusts the operating state of the regulating unit 1 using a built-in control algorithm, thereby achieving precise adjustment of the air intake of the ventilation duct 100. This intelligent adjustment method can quickly respond to temperature changes, ensuring that the internal temperature of the welding lamp box remains within a preset range, avoiding a decline in welding quality due to excessively high or low temperatures. Furthermore, a stable temperature environment also helps improve the strength and reliability of the welded joint, thus enhancing welding quality and stability.

[0063] Optionally, it also includes a ventilation duct 100 and two fans 200. The ventilation duct 100 includes an air outlet duct and two air inlet ducts. One end of each air inlet duct is connected to one of the fans 200, and the other end of each air inlet duct is connected to the air outlet duct. The air outlet duct faces the lamp tube 300.

The exhaust ducts are also known as air inlets, and the blower duct is also known as air outlets. Each air inlet duct is connected to a fan 200 to collect the air blown out by the fan 200 and blow it to the lamp tube 300 through the air outlet duct, thereby enabling flexible adjustment of the internal temperature of the welding lamp box.
