DETAILED DESCRIPTION

[0023] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. It should be understood by those skilled in the art that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0024] like Figures 1 to 3 As shown, a high-precision annular grasping, positioning and stripping mechanism includes: a front-end limiting block 1, a left-end limiting block 2, a rear-end limiting block 3, a right-end limiting block 4, a limiting stripping substrate 5, a rotating hook 6, a cam roller 7, a cam roller mounting block 8, a hook cylinder connecting block 9, a hook opening and closing cylinder 10, a stripping rod 11, a stripping cylinder 12 and a frame 13; the stripping cylinder 12 is arranged on the inner rear side of the frame 13; the hook opening and closing cylinder 10 is arranged at the upper end of the stripping cylinder 12; the hook cylinder connecting block 9 is arranged at the front end of the inner part of the frame 13; the cam roller mounting block 8 is arranged at the front end of the hook cylinder connecting block 9; the cam roller 7 is connected to the hook opening and closing cylinder 10 through the cam roller mounting block 8 and the hook cylinder connecting block 9; a limiting stripping substrate 5 is arranged at the front end of the frame 13; A rear end limit block 3 is set in the middle, and a front end limit block 1 is correspondingly set in six directions around the rear end limit block 3; a left end limit block 2 and a right end limit block 4 are respectively set on the left and right sides of the center of the front end limit block 1 and the rear end limit block 3; a stripping rod 11 is set on the front and back sides of the center of the front end limit block 1 and the rear end limit block 3; the stripping rod 11 slides up and down in the sliding circular hole of the limiting stripping substrate 5, and the stripping rod 11 and the stripping cylinder 12 are floatingly connected through an up and down sliding mechanism, and the stripping cylinder 12 moves up and down to realize the stripping action of the target object; the rotating hook 6 is set in the middle of the front end limit block 1, and the bottom end passes through the limiting stripping substrate 5 and is slidably connected with the cam rotor 7. At this time, the rotating hook 6 is connected to the rotatable opening and closing positioning cavity through a hinge pin to grab and open and close the target object.

[0025] Furthermore, the device also includes a positioning column 14; there are two positioning columns 14, which are respectively installed on both sides of the limiting stripping substrate 5 and connected as a whole to form a precise limiting and positioning cavity for the target.

[0026] Furthermore, the limiting stripping substrate 5 is elliptical.

[0027] Furthermore, the limiting stripping substrate 5 is made of metal material.

[0028] Furthermore, the stripping cylinder 12 is fixed to the frame 13 by screws.

[0032] The device is guided by the positioning column 14 and moves downward to achieve precise positioning with the material removal seat. The entrance of the positioning cavity is chamfered, and the target is guided to enter the positioning cavity. The target object on the positioning seat can be roughly positioned, and the claw is opened before taking the target object; after the target object enters the precise positioning cavity, the claw is closed and hooks the bottom of the target object, so that the target object is positioned and removed without falling; then the device is moved to the stripping position, and precise positioning is achieved with the positioning column 14 and the target carrier / mold. The claw is opened, and the stripping rod 11 strips the target object to the carrier / mold, achieving precise and stable stripping.
