[0020] As Figure 1 shown, the present utility model provides a roller turning plate mechanism, including a placement rack 1, a roller plate 2 symmetrically arranged at the middle position inside the placement rack 1, and the roller plate 2 is connected by a connecting rod 8. A plurality of brackets 4 are evenly distributed around the axis of the roller plate 2. The brackets 4 are installed inside the placement rack 1. The rotating rollers 5 are movably installed on the brackets 4. A groove is provided on each rotating roller 5. The roller plate 2 is placed in the groove. A chain 9 is installed on the inner wall of one side of the roller plate 2. The chain 9 is meshed and driven with the gear 10. The gear 10 is movably installed inside the placement rack 1 through the motor 11. A plate conveying assembly 3 is installed at the middle position of the roller plate 2.

[0021] When the motor 11 is turned on, the motor 11 drives the gear 10 to rotate along the chain 9, thereby driving the drum plate 2 to rotate. As a result, the plate conveying assembly 3 can be driven to rotate around the drum plate 2. The plate transportation assembly 3 is used to transport workpieces. Thus, the drum plate 2 can drive the workpieces to rotate to any angle and stop, so as to meet the requirements of various angles in subsequent processes.

[0022] Furthermore, a positioning block 6 is installed on the drum plate 2. At the same time, the positioning pin 7 is installed on the placement rack 1 through a support frame. The positioning pin 7 is used to position the initial position of the drum plate 2, so as to ensure accurate control of the position of the workpiece.

[0023] Specifically, please refer to Figure 2 , the plate conveying assembly 3 includes fixed plates 313 symmetrically installed inside the drum plate 2, a front plate 302, a middle plate 303 and a rear plate 304 sequentially arranged movably between the fixed plates 313. The front plate 302 and the rear plate 304 are movably installed at both ends of the lead screw. The middle plate 303 is threadedly installed on the lead screw. At the same time, the front plate 302 and the rear plate 304 are connected by a guide rod 301, and the guide rod 301 passes through the middle plate 303. At the same time, a motor one is installed at one end of the lead screw in a driving manner. Thus, when the motor one is turned on, the middle plate 303 moves back and forth along the guide rod 301; on the side of the front plate 302 close to the middle plate 303 and on the side of the middle plate 303 close to the front plate 302, driving wheels and a conveyor belt 311 are symmetrically arranged in a driving connection. A motor two is installed on the driving wheel. In order to guide the movement of the workpiece, limiting plates 312 are symmetrically installed on the inner walls of the front plate 302 and the middle plate 303. One side of the conveyor belt 311 is placed on the limiting plate 312, so that the workpiece is clamped between the conveyor belts 311 and conveyed.

[0024] When the motor two is turned on, the motor two drives the driving wheel to rotate, thereby driving the conveyor belt 311 to transport the workpiece. And in order to adapt to workpieces of different models, the distance between the middle plate 303 and the front plate 302 can be adjusted by turning on the motor one, so that the plate transportation assembly 3 can adapt to transporting workpieces of different models.

[0025] Furthermore, in order to limit the movement position of the workpiece, a stop block 305 is installed at the output end of the middle plate 303 through a cylinder one 306. Thus, when the workpiece is transported to the end point position, the cylinder one 306 is turned on, and the stop block 305 is pushed by the cylinder one 306 to block the workpiece from moving forward continuously. And when the angle rotation is over, the cylinder one 306 retracts the stop block 305, so that the workpiece can continue to move to the next working station.

[0026] Please refer to Figure 2-3, in order to cooperate with the stopper 305 to further limit the workpiece, a pressing block 307 is movably installed on both the front plate 302 and the middle plate 303 through the second cylinder 308. A number of protrusions 309 are provided on the pressing block 307, and the protrusions 309 pass through the front plate 302 and the middle plate 303. When the second cylinder 308 is opened, the protrusions 309 move downward, thereby pressing the workpiece onto the limiting plate 312, further restricting the movement of the workpiece; in order to prevent the pressing block 307 from affecting the transportation of the workpiece by the conveyor belt 311 when it is in the non-working state, please refer to Figure 4 , it is designed that the conveyor belt 311 cooperates with the conveyor wheel 310 to bypass the protrusion 309. The conveyor wheel 310 is movably installed on the front plate 302 and the middle plate 303. Therefore, the conveyor belt 311 will not be stretched due to the frequent movement of the pressing block 307, resulting in a reduction in the service life of the conveyor belt 311, nor will it affect the normal transportation of the workpiece by the conveyor belt 311 when the pressing block 307 is not working.

[0027] The motor 11, the first motor, the second motor, the first cylinder 306 and the second cylinder 308 are communicatively coupled to the control panel.

[0028] The control panel contains a PLC controller, which is a programmable numerical control system. As the central control system, the PLC uses a touch screen to realize the program input and operation control of the whole machine, realizing the full automation of the transportation process. The control system can be used as a system that connects each actuator to move according to a logical trajectory, and controls the actuator to operate according to the required operation steps through programming.

[0029] This device can drive the workpiece to rotate to any angle and stop, thus meeting the requirements of various angles in subsequent processes; at the same time, it can adapt to the transportation of workpieces of different models.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
