In the production process of automotive window film, testing equipment is needed to test the heat insulation performance and light blocking performance of the window film. However, the testing instruments currently on the market only test the transmitted light and cannot adjust the light angle and position, which cannot meet the testing requirements.

The moving guide rail assembly is horizontally arranged in the middle of the frame, and includes two parallel linear guide rails. The two linear guide rails are connected to the window film fixing frame via the electric travel slider. Stepper motors are installed at the connection points between the window film fixing frame and the electric travel slider on both the front and rear sides of the frame. An ultraviolet heat lamp is installed on the upper part of the frame, and a temperature sensor and a light sensor are installed on the lower part of the frame, directly opposite the ultraviolet heat lamp. A control center is located on the side of the frame, and the control center is connected to the electric travel slider, the stepper motor, the ultraviolet heat lamp, the temperature sensor, and the light sensor, respectively.
