The electric fan structure includes an electric blind installed on the casing. The electric blind includes a frame, which is fixedly connected to the casing by a fixing rod. A number of blades evenly spaced and parallel to the horizontal plane are installed in the frame through bearings. A driving motor is fixedly provided on the back of the frame.

[0012] A processing method for a car roof production line, characterized in that it comprises the following steps:

[0013] S1, loading stage: the lower nail frame is placed on the loading table through operation, and then the production materials are placed on the lower nail frame. After the placement is completed, the upper nail frame is placed on the lower nail frame accordingly, so that the production materials are located between the upper nail frame and the lower nail frame. Finally, the material pressing structure is controlled to fix the production materials on the nail frame and reset;

[0014] S2, heating stage: after the pressing structure fixes the production raw materials on the nail frame, the driving motor in the transmission mechanism is controlled to operate, so that the driving motor drives the active synchronous wheel to rotate, and the active synchronous wheel rotates to drive the synchronous belt to move the nail frame into the heating mechanism. When the nail frame moves between the heating components, the transmission mechanism is controlled to stop running, and then the production raw materials on the nail frame are heated by controlling the heating components;

[0015] S3, stamping stage: when the heating mechanism finishes heating the raw materials on the nail frame, the driving motor in the transmission mechanism is controlled to operate, so that the driving motor drives the active synchronous wheel to rotate, and the active synchronous wheel rotates to drive the synchronous belt to move the nail frame into the stamping mechanism. When the nail frame moves to the stamping table, the transmission mechanism is controlled to stop operating, and then the heating component is controlled to stop heating. Then, the hydraulic press is controlled to drive the hydraulic rod to drive the stamping mold to stamp and form the raw materials on the nail frame and reset it. While controlling the hydraulic press to operate, the electric air guide plate structure away from the electric fan structure is controlled to operate, so that the stepper motor drives the air guide plate to open, so that the wind irregularly enters the casing and is discharged through the air guide plate to achieve the effect of rapid heat dissipation;

[0016] S4, heat dissipation stage: when the stamping is completed, the driving motor in the transmission mechanism is controlled to operate, so that the driving motor drives the active synchronous wheel to rotate, and the rotation of the active synchronous wheel drives the synchronous belt to transmit the nail frame to the outside of the device body. After the transmission is completed, the transmission mechanism is controlled to stop running, and at the same time, the electric air guide plate structure on both sides is controlled to operate, so that the stepper motors on both sides drive the air guide plates to close, and finally the electric fan structure is controlled to stop running;

[0017] S5, cooling stage: after the conveying mechanism conveys the nail frame to the outside of the device body, the operator controls the manipulator to place the nail frame at a designated position for cooling. After cooling, the operator uses special tools to disassemble the nail frame and take out the finished product.

[0018] The present invention is further configured as follows: in S2, a temperature detection device is further provided in the housing, the temperature detection device comprises a temperature detection module for detecting the temperature of the production raw material on the nail frame and a receiving control module for receiving detection data of the temperature detection module and controlling the heating mechanism, and the detection method of the temperature detection device comprises the following steps:

[0019] S21, heating the production materials fixed by the nail frame by controlling the heating component on the casing, and controlling the electric air guide plate structure and the electric air fan structure on the side close to the electric air fan structure to operate, so that the stepping motor on the side close to the electric air fan structure drives the air guide plate to open, and the fan drives the fan blades to rotate and discharge air, and the driving motor drives the blades to flip up and down through the connecting rod mechanism, so that the wind irregularly enters the casing to achieve the effect of turbulence and rapid temperature rise;

[0020] S22, preset the threshold value of the heating temperature required for the production raw material as T, and detect the current production raw material temperature T1 at the same time. If T1≥T, it is determined that the production raw material has been heated and can enter the stamping stage. If T1<T, it is determined that the production raw material is not heated sufficiently, and the production raw material continues to be heated for a heating time of A, and the process goes to S23 to continue detection;

[0021] S23, after the A time period, detect the temperature T2 of the production raw materials. If T2 ≥ T, it is determined that the production raw materials have been heated and can enter the stamping stage. If T2 < T, go to S22 for another detection.

[0022] The beneficial effects of the present invention are:

[0023] 1. Compared with the prior art, the automobile roof production line and processing method of the present invention configure the heating component as double-sheet far-infrared heating, so that the production materials on the nail frame are heated between the double-sheet far-infrared heating. This makes the heating speed of the production materials fast and the heating more uniform, ensuring that the subsequent stamping and forming of the production materials will not be affected, thereby improving production efficiency.

[0024] 2. The automobile roof production line and processing method of the present invention can further quickly and evenly heat the production materials on the nail frame through the electric air guide plate structure and the electric fan structure. When heating is needed, the stepper motor in the electric air guide plate structure close to the electric fan structure is controlled to open the air guide plate, and then the drive motor and fan in the electric fan structure are started to allow wind to enter the casing irregularly through the up and down swinging blades through the opened air guide plate, and then cooperate with the heating component to achieve rapid and uniform heating. When the heating is completed and heat is required, it is only necessary to control and drive the stepper motor in the electric air guide plate structure away from the electric fan structure to open the air guide plate, so that the hot air is blown out of the casing, and the heat is also fast. When all is completed, the stepper motors in the electric air guide plate structures on both sides are driven to close the air guide plates, and then the electric fan structure is stopped. The electric air guide plate structure can also play a dust-proof role when it is not used for a long time.

[0025] 3. In the present invention, by setting up a conveying mechanism, it is convenient to load, heat and punch the nail frame from the nail frame feeding mechanism to the heating mechanism and finally to the punching mechanism, thereby realizing automation.

[0026] 4. The present invention has a reasonable structure, is easy to manufacture, and is simple to operate. It avoids the defects of the prior art and is suitable for popularization and application. BRIEF DESCRIPTION OF THE DRAWINGS
