Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-4 The rotating device based on PLC control shown includes a base 1, a protective shell 2 fixedly connected to the top surface of the base 1, a PLC control module on one side of the protective shell 2, a rotating rod 3 rotatably connected to the top surface of the base 1, a support plate 4 fixedly connected to the top surface of the rotating rod 3, a plurality of fastening screws 20 on the top surface of the support plate 4, a turntable 5 on the top surface of the support plate 4, the bottom of the fastening screws 20 passing through the turntable 5 and threadedly connected to the support plate 4, four tracks on the bottom surface of the turntable 5, a track 1 51 at the center of the turntable 5, a track 2 52 on the turntable 5 surrounding the track 1 51, a track 3 53 on the turntable 5 surrounding the track 2 52, and a track 4 54 on the turntable 5 surrounding the track 3 53.

[0034] A sensor trigger block 68 is threaded along the 315° direction of the center line of turntable 5, and this sensor trigger block 68 is located on track 54. Sensor trigger blocks 61, 62, 63, 64, 65, 66, 67, and 68 constitute a sensor trigger module. One side of the protective shell 2 is provided with a horizontal plate 7 that moves along the outer wall of the protective shell 2. A mounting plate 8 is fixedly connected to one side of the horizontal plate 7. Four detachable sensors 9 are inserted into the mounting plate 8. The spacing between the four sensors 9 is the same as the spacing between adjacent tracks. A drive device is provided inside the protective shell 2.

[0035] By setting four tracks at the bottom of turntable 5, and installing different numbers of sensor trigger modules or different track sensor trigger modules at different angles along the tracks at the bottom of turntable 5, the rotation angle of turntable 5 can be controlled simply by the sensor trigger module corresponding to the sensor 9 signal when turntable 5 needs to rotate by a corresponding angle.

[0036] like Figure 1 As shown, the outer wall of the sensor 9 is threaded with two fastening nuts 10. The two fastening nuts 10 are located on both sides of the mounting plate 8, and the fastening nuts 10 facilitate the fixing of the sensor 9 to the mounting plate 8.

[0037] like Figure 1As shown, two handles 18 are fixedly connected to the top surface of the base 1, and mounting screws 19 are fixedly connected to the four corners of the top surface of the base 1. The handles 18 facilitate the movement after the mounting screws 19 are removed.

[0038] like Figure 2 As shown, the drive device includes a servo motor 14 fixedly connected to one side of the protective shell 2. The output end of the servo motor 14 is fixedly connected to a synchronous pulley 15. A worm gear 171 is rotatably connected inside the protective shell 2. One end of the worm gear 171 is fixedly connected to a synchronous pulley 17. A synchronous belt 16 is rotatably connected between the synchronous pulley 17 and the synchronous pulley 15. A turbine 31 is fixedly connected to the outer wall of the rotating rod 3. The turbine 31 is meshed with the worm gear 171.

[0039] like Figure 1 and Figure 3 As shown, two grooves 11 are provided on one side of the protective shell 2. A slider 71 is slidably connected inside each groove 11. The two sliders 71 are fixedly connected to one side of the horizontal plate 7. Two connecting rods 72 are fixedly connected to the bottom surface of the horizontal plate 7. A locking device 13 is fixedly connected to the bottom end of the two connecting rods 72.

[0040] like Figure 3 As shown, the locking device 13 includes two U-shaped plates 131 fixed to one side of two connecting rods 72. One end of the two U-shaped plates 131 is fixedly connected to a top plate. A through groove 132 is opened inside the U-shaped plate 131. A slide rod 133 is slidably connected inside the through groove 132. Insert rods 134 are fixedly connected to both ends of the slide rod 133. Insert holes 12 that are adapted to the insert rods 134 are opened on the inner wall of the slide groove 11. A pull rod 135 is fixedly connected to one side of the slide rod 133. The pull rod 135 passes through the top plate. A spring 136 is fixedly connected between the top plate and the slide rod 133.

[0041] When the pull rod 135 is pulled, the slide rod 133 moves in the through groove 132. The movement of the slide rod 133 causes the insertion rod 134 to move, making it easier for the insertion rod 134 to separate from the insertion hole 12. At this time, the locking device 13, the connecting rod 72, and the horizontal plate 7 can be pushed to move up and down. Thus, when facing sensors 9 of different sizes, the vertical distance between the sensor 9 and the sensor trigger module can be adjusted to avoid collision between the sensor 9 and the sensor trigger module.

[0042] The working principle of this utility model is as follows: In use, the PLC first sends a pulse signal to the driver of the servo motor 14, causing the servo motor 14 to drive the synchronous pulley 15 to rotate. Then, the synchronous pulley 15 drives the synchronous belt 16 to rotate, the synchronous belt 16 drives the synchronous pulley 17 to rotate, the synchronous pulley 17 drives the worm gear 171 to rotate, the worm gear 171 drives the turbine 31 to rotate, the turbine 31 drives the rotating rod 3 to rotate, the rotating rod 3 drives the support plate 4 to rotate, and the support plate 4 drives the turntable 5 to rotate. When the sensor trigger module below the turntable 5 rotates to the top of the sensor 9, the sensor 9 is in the on state. The PLC receives the signal from the sensor 9 and then adjusts the servo motor 14 according to the signal from the sensor 9, causing the servo motor 14 to stop moving and the turntable 5 to stop rotating.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
