Detailed implementation manners

[0021] As Figures 1-3 shown, the present utility model provides an automatic flipping mechanism, including a support frame 100, a fixed frame 200 and a flipping assembly 300. A notch 101 is provided on the upper surface of the support frame 100. The flipping assembly 300 is arranged inside the notch 101, and the fixed frame 200 is arranged inside the flipping assembly 300. The flipping assembly 300 includes a drive motor 301, a rotating rod 302, a connecting column 303, a flipping rod 305, a connecting rod 307 and a suction cup 306. The drive motor 301 is arranged inside the fixed frame 200. The rotating rod 302 is arranged at the output end of the motor. The connecting column 303 is sleeved outside the rotating rod 302. The flipping rod 305 is arranged at the end of the connecting column 303. The connecting rod 307 is arranged between the flipping rod 305 and the connecting column 303. The suction cup 306 is arranged on the surface of the flipping rod 305.

[0022] Furthermore, in this embodiment, a speed reducer 309 is arranged between the drive motor 301 and the rotating rod 302. The speed reducer 309 is a double-shaft speed reducer 309. The output end of the drive motor 301 is in transmission connection with the speed reducer 309. Rotating rods 302 are arranged on both the left and right sides of the upper end of the speed reducer 309. The speed reducer 309 is in transmission connection with the rotating rods 302. Fixed seats 304 are arranged outside the rotating rods 302. The fixed seats 304 are screwed to the inside of the fixed frame 200. The drive motor 301 drives the speed reducer 309, and the speed reducer 309 controls the rotation of the rotating rods 302 at both ends. The position of the rotating rods 302 is stabilized by the fixed seats 304.

[0023] In this embodiment, at least two connecting columns 303 are equidistantly arranged on the outer side of the rotating rod 302. The connecting columns 303 are screwed to the rotating rod 302. The rotating rod 302 is rotatably connected to the fixed seat 304, and the connecting columns 303 are driven to rotate together by the rotating rod 302.

[0024] In this embodiment, the front end of the connecting column 303 is sleeved with the rear end of the flipping rod 305. The connecting rod 307 horizontally penetrates through the connection part of the connecting column 303 and the flipping rod 305. The flipping rod 305 is connected to the rotating rod 302 through the connecting column 303, and the flipping rod 305 is connected to the connecting column 303 through the connecting rod 307 and horizontally passes through the connection parts of all the flipping rods 305 and the connecting columns 303, so as to realize the synchronous rotation of all the flipping rods 305.

[0025] In addition, the numbers of the flipping rods 305 and the connecting columns 303 are adjusted individually according to the size of the steel plate, so as to improve the flexibility of the mechanism.

[0026] In this embodiment, the suction cup 306 is a vacuum suction cup 306. A connecting head 308 is fixed to the bottom end of the suction cup 306. The connecting head 308 is in threaded fit with the flipping rod 305. At least three suction cups 306 are equidistantly arranged on the flipping rod 305. The suction cup 306 is conveniently connected to the vacuum pumping device through the connecting head 308, and the number of the suction cups 306 is set according to the size of the steel plate to ensure that the suction cups 306 can hold the steel plate.

[0027] In this embodiment, a notch 101 for the flipping assembly 300 to flip is formed on the outer side of the fixed frame 200. The flipping assembly 300 is movably connected to the support frame 100 and the fixed frame 200 respectively through the notch 101. The flipping assembly 300 is facilitated to flip through the notch 101, and the flipping assembly 300 can be placed when not in use.

[0028] In this embodiment, a proximity switch is embedded on the surface of the flipping rod 305, and the distance signal between the suction cup 306 and the steel plate is detected through the proximity switch.

[0029] Specifically, the automatic flipping mechanism is used in conjunction with the existing automatic feeding mechanism. The control of the flipping mechanism is set and controlled together by the controller of the existing automatic feeding mechanism. After the automatic feeding is completed, the driving motor 301 is driven by the preset signal of the feeding mechanism controller to drive the reducer 309 to rotate. The reducer 309 controls the synchronous rotation of the flipping rod 305 connected to the rotating rod 302 through the connecting column 303, thereby controlling the flipping of the suction cup 306 towards the steel plate. A proximity switch is set on the flipping rod 305. When the suction cup 306 approaches the steel plate, it sends a in-place signal to the controller. The controller controls the vacuum pumping device to perform vacuum adsorption using the suction cup 306 until the suction cup 306 adsorbs the steel plate. The proximity switch sends a signal to the controller, and the controller controls the driving motor 301 and the reducer 309 to reverse, rotates the flipping rod 305 back to its original position, and drives the adsorbed steel plate together to complete the flipping action;

[0030] The signal principle of the proximity switch is that when an object approaches the sensor, the capacitance between it and the sensor will change, and this change is converted into a voltage signal to trigger the switch to act.

[0031] It should be noted that the control method of this application document is automatically controlled through the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the art. This application will not explain the control method and circuit connection in detail.
