[0034] The working principle of the printed circuit flattening device for a vehicle-mounted laser radar provided by the utility model is as follows:

[0035] By letting the No. 2 electric push rod 16 drive the fixed plate 17 to move downward, the printing screen 18 equipped with the No. 3 spring 19 can print silver paste on the circuit board body 26 to improve the printing flatness effect, then start the No. 1 electric push rod 13, the No. 1 electric push rod 13 will extend and drive the pressure plate 14 to squeeze the sliding plate 4 equipped with the No. 2 spring 11, so that the elastic sliding plate 4 moves downward along the two vertical rods 3, which will drive the mounting seat 8 equipped with the No. 1 spring 10 on the sliding plate 4 to adjust to a suitable height, and then use the flattening roller 9 at the mounting seat 8 to elastically flatten the circuit board body 26 on the rubber placement plate 25, so as to protect the circuit board body 26, and use the double flattening method to improve the flattening effect of the flattening device and avoid the situation that it is easy to warp;

[0036] By placing multiple circuit board bodies 26 respectively on the rubber placement plate 25 at the tooling plate 24, the circuit board bodies 26 can be installed with the first cross plate 28 and the second cross plate 29 with the No. 4 spring 31. Then, the elastic force of the No. 4 spring 31 can be used to allow the two rubber clamps 30 to adaptively clamp and fix circuit board bodies 26 of different specifications. The use of the rubber placement plate 25 can increase the friction with the circuit board body 26 and improve the stability of the circuit board body 26 when it is fixed. Then, the output shaft of the servo motor 37 drives the active gear rotating rod 36 to rotate. The active gear rotating rod 36 will also drive the meshing threaded gear rotating rod 21, so that the connecting plate 23 on the threaded gear rotating rod 21 can move to the right. In this way, multiple circuit board bodies 26 can be moved in sequence and multiple leveling operations can be performed to improve the leveling quality of the circuit board body 26.

Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
