As shown in Figures 1, 2, 3, 4, and 5, the specific steps of the working method of a three-screen rotating and translational advertising display device of the present invention are as follows:

The initial position is set when the left, middle and right screens are all in the vertical position and the distance between the borders of two adjacent screens is 830mm. The left and right screens can rotate around their own axes and translate horizontally, and the middle screen can only rotate around their own axes. According to the instructions sent by the motion control card of the industrial computer to the servo motor driver, the first servo motors 9 of the three rotary drive devices III and the second servo motors 18 of the two translation drive devices IV operate. The first servo motor 9 is equipped with a reducer 8 to increase the torque, and the first coupling 6 drives the main connecting shaft 3 and then drives the screen clamping device II connected to the end flange and the liquid crystal screen I to rotate Rotational motion around its own axis.

At the same time, the output power of the second servo motor 18 of the translation drive device IV on the left and right sides is transmitted by the second coupling 17 through the rotation of the ball screw, driving the ball nut pair 11 to translate horizontally, and then through the connecting plates of the slide rails on both sides. 10 and the rotating device mounting plate 16 drive the rotating drive device III to translate in the horizontal direction along the two guide rails 14 equipped with the guide rail slider 12 . In this way, the left and right screens can be rotated and translated, and the middle screen can only be rotated.

Set the origin for the servo motor driver through the RS485 communication protocol, and read the position information of the servo motor encoder in real time through the ModBus communication protocol during the movement to prevent the horizontal direction from exceeding the limit or the rotation angle. After the device action is completed and the screen display is completed, the value read through the ModBus communication protocol is converted to the motion control card, and the motion control card sends it to five servo motors. For safety reasons, ensure that the left and right screens are returned first in the horizontal direction. The distance between the two screens is 830mm zero point, three screens rotate to their own vertical zero point at the same time. In the case that the adjacent screens do not collide with each other through Blender software motion tracking, the motion control card can be programmed to realize different changing patterns of screens moving with the screen. During the movement, if the three screens rotate 45 degrees clockwise at the same time and the left and right screens move 200mm to the middle, the images displayed on the three screens also rotate 45 degrees clockwise, and the entire screen moves 200mm to the middle, that is, the display screens at different times change with each other. Adapt to changes in the state of motion.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
