In this utility model, the temperature sensor is used to detect the temperature inside the upper cavity to avoid overheating, and the humidity sensor is used to measure the humidity inside the upper cavity, so as to determine whether the drying is sufficient based on the internal humidity. Excess hot air enters the lower cavity through the perforated plate. The PCB printed circuit board to be dried is placed on the grid plate.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1 , Figure 2 , Figure 3A PCB (Printed Circuit Board) drying device includes a housing 1. The interior of the housing 1 is divided into an upper cavity and a lower cavity by a perforated plate 7. An electrically driven rotating gripper 9 is installed on the inner side wall of the upper cavity of the housing 1. The electrically driven rotating gripper 9 is used to clamp the PCB and can rotate the PCB while clamping it, thereby ensuring that the PCB is heated more evenly by the infrared heating tube 12 and the hot air assembly, avoiding uneven heating, reducing damage to the PCB, and preventing incomplete drying. An infrared heating tube 12 and a hot air assembly that blows hot air into the upper cavity are installed at the top of the interior of the upper cavity of the housing 1. The simultaneous use of the infrared heating tube 12 and the hot air assembly improves drying efficiency. A grid plate 8 is fixed inside the lower cavity by a bracket 15. A first door 5 for sealing the upper cavity is installed on the side of the chamber 1, and a second door 6 for sealing the lower cavity is installed on the side of the chamber 1. A temperature sensor 13 and a humidity sensor 14 are installed on the inner wall of the upper cavity of the chamber 1. The temperature sensor 13 is used to detect the temperature inside the upper cavity to avoid overheating, and the humidity sensor 14 is used to measure the humidity inside the upper cavity, so that the drying can be judged based on the internal humidity. A touch screen 4 is installed on the side of the chamber 1. An exhaust mesh 2 is opened on the side of the lower cavity of the chamber 1. Excess hot air enters the lower cavity through the perforated plate 7. The PCB printed circuit board to be dried is placed on the mesh plate 8. The incoming hot air can preheat the PCB printed circuit board, so as to better realize the subsequent rapid drying of the PCB printed circuit board. Finally, the exhaust gas is discharged through the exhaust mesh 2.

[0015] Reference Figure 3 The hot air assembly includes a hot air blower 3, an air duct 11, and a main air pipe 10. The hot air blower 3 is installed on the top of the housing 1. The outlet of the hot air blower 3 is connected to the main air pipe 10 through the air duct 11. The main air pipe 10 is fixed to the top of the inner cavity of the housing 1. The main air pipe 10 has nozzles. The hot air generated by the hot air blower 3 enters the main air pipe 10 through the air duct 11 and is finally sprayed into the lower cavity through the nozzles on the main air pipe 10.

[0016] Working principle: During use, the simultaneous heating of infrared heating tube 12 and hot air assembly improves drying efficiency. The electric rotating gripper 9 holds the PCB printed circuit board and rotates it simultaneously, ensuring more even heating by the infrared heating tube 12 and hot air assembly, preventing uneven heating, reducing damage, and ensuring thorough drying. Temperature sensor 13 detects the temperature inside the upper cavity to prevent overheating, while humidity sensor 14 measures the humidity inside the upper cavity to determine if drying is sufficient. Excess hot air enters the lower cavity through perforated plate 7. The PCB printed circuit board to be dried is placed on the grid plate 8, and the incoming hot air preheats it, facilitating faster drying. Finally, exhaust gas is discharged through exhaust mesh 2.

[0017] The operating principle of the hot air assembly is as follows: the hot air generated by the hot air blower 3 enters the main air pipe 10 through the air guide pipe 11, and finally is sprayed into the lower cavity through the nozzle on the main air pipe 10.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
