A numeric keyboard 803 electrically connected to the single chip microcomputer 801 is arranged on the side of the function button 805 .

[0022] Specifically, the support frame 3 is a height-adjustable hydraulic support seat, and the support frame 3 is fixed on the ground. This arrangement facilitates the adjustment of the height of the conveyor belt 1 of the production line, so as to adapt to gantries 5 and darkrooms 4 of different sizes.

[0023] Specifically, the photoelectric signal processor 9 is connected to the photoelectric detector 12 via a commutation joint 11. This arrangement facilitates adjusting the receiving angle of the photoelectric detector 12 via the commutation joint 11 when necessary, so that the photoelectric detector 12 can receive the laser signal reflected by the steering arm 2 of the vehicle to be detected.

[0024] Specifically, two blackout cloths 16 are arranged on the side of the darkroom 4. The conveyor belt 1 of the production line drives the steering arm 2 of the car to be inspected to pass through a blackout cloth 16 and enter the darkroom 4 for inspection, and then drives the steering arm 2 of the car to be inspected to be transported out through another blackout cloth 16.

[0027] Working principle: When using this device, first, the microprocessor 6 is electrically connected to the external power grid, and the external power grid is used to power this device, and the frequency of the WIFI communication module 7 is coordinated with the frequency of the remote control end of the staff, and the automobile steering arm 2 to be tested is placed above the conveyor belt 1 of the production line. The conveyor belt 1 of the production line controls the automobile steering arm 2 to be tested to pass through the blackout cloth 16 and enter the darkroom 4. Under the control of the microprocessor 6, the photoelectric signal processor 9 generates a laser through the laser transmitter 10, and after irradiating it on the automobile steering arm 2 to be tested, it is reflected out, and the reflected laser is received by the photoelectric detector 12. The photoelectric detector 12 feeds back the received laser signal information to the photoelectric signal processor 9 for processing, and the processed result is fed back to the microprocessor 6. The microprocessor 6 compares the detected photoelectric signal with the feedback signal of the standard part, and detects the flatness and bending angle of the automobile steering arm production surface by laser reflection measurement. The detection result is stored in the microprocessor 6. When the detection result does not meet the standard, a wireless signal is sent through the WIFI communication module 7 to prompt the staff to pick up the automobile steering arm 2 to be tested and collect it for recycling and reprocessing.
