[0025] The electric telescopic rod 4 is set to model ZC01A, the mounting plate 5, the flipping mechanism 6, the robot arm clamping mechanism 7 is model AHVG, the positioning plate 8, and the limit rod 9. The electric telescopic rod 4 can be controlled to adjust the distance between the left and right robot arm clamping mechanisms 7, so that the robot arm clamping mechanism 7 can clamp and fix molds or workpieces of different sizes. After clamping, the flipping mechanism 6 is controlled to flip the robot arm clamping mechanism 7 according to the operating angle.

[0026] like Figure 2 As shown, the utility model provides a technical solution for a robot arm flipping device: the flipping mechanism 6 includes a driving motor 61, the output shaft of the driving motor 61 passes through one end of the mounting plate 5 and is fixedly connected to a gear 62, a driven gear 63 is arranged above the gear 62, and the driven gear 63 is rotatably connected to a bearing 64 at one end away from the robot arm clamping mechanism 7, and the other end of the bearing 64 is fixedly connected to the surface of the mounting plate 5, and the driven gear 63 is fixedly connected to a fixing sleeve 65 at one end away from the bearing 64, and the mounting plate 5 and the robot arm clamping mechanism 7 are connected through the cooperation between the bearing 64 and the fixing sleeve 65, and the bottom of the driving motor 61 is fixedly connected to the top of the connecting plate 11.

[0027] like Figure 3-4As shown, the utility model provides a technical solution for a robot hand turning device: the latch teeth on the gear 62 mesh with the latch teeth on the driven gear 63, and the gear 62 meshes with the driven gear 63, so that the driven gear 63 is driven to rotate while the gear 62 rotates. The mounting plate 5 is fixedly connected to the front and rear sides of the driven gear 63, and the ends of the two latch plates 51 away from the mounting plate 5 are fixedly connected to the arc plate 52. The middle side of the end of the robot hand clamping mechanism 7 close to the mounting plate 5 is fixedly connected to the connecting column 72, and the outer wall of the connecting column 72 is fixedly connected to the annular plate 71, an annular groove 710 is formed at one end of the annular plate 71 away from the robot arm clamping mechanism 7, and the end of the connecting column 72 away from the robot arm clamping mechanism 7 is fixedly connected to the inner wall of the fixed sleeve 65, and the driven gear 63 and the robot arm clamping mechanism 7 are fixedly connected through the fixed sleeve 65 and the connecting column 72, so that the driven gear 63 can drive the robot arm clamping mechanism 7 to rotate, and the inner wall of the annular groove 710 is slidably connected to the outer wall of the arc plate 52, and the arc plate 52 moves along the inner circumference of the annular groove 710, thereby improving the stability of the flipping work of the robot arm clamping mechanism 7.

[0030] like Figure 1-5 As shown, when in use, first, the control panel 10 is operated to start the left and right electric telescopic rods 4, so that the output end of the electric telescopic rod 4 drives the mounting plate 5 to telescopically move. During the movement, the sliding sleeve 54 on the mounting plate 5 slides along the outer wall of the limit rod 9, thereby improving the displacement stability of the robot arm clamping mechanism 7, adjusting the distance between the left and right robot arm clamping mechanisms 7, and controlling the robot arm clamping mechanism 7 to clamp and fix molds or workpieces of different sizes. After the fixation is completed, by starting the drive motor 61, the output shaft of the drive motor 61 drives the gear 62 to rotate. Since the latch teeth on the gear 62 are engaged with the latch teeth on the driven gear 63, the gear 62 drives the driven gear 63 to rotate while rotating, so that the driven gear 63 drives the robot arm clamping mechanism 7 to flip through the fixing sleeve 65. During the rotation, the arc plate 52 on the clamping plate 51 performs a circular motion along the annular groove 710 in the annular plate 71, thereby making the overall structure compact and improving the stability of the flipping work.
