The embodiments of the present application will be described in detail below with reference to the accompanying drawings by means of specific embodiments and application scenarios thereof.

Referring to fig. 1 to 6, an embodiment of the present application discloses a material taking mechanism 100 for picking up an annular material piece 600, where the annular material piece 600 may be deformed, and an elastic material, such as rubber, plastic, etc. may be used for the annular material piece 600, and of course, other materials may be used, which is not limited herein. In a more specific embodiment, the annular material 600 may be a rubber ring, but may be other components. The disclosed take out mechanism 100 includes a take out head 110, and during the take out process, at least a portion of the take out head 110 may be introduced into the interior of the annular part 600 to effect take out, so as to facilitate movement of the annular part 600 to effect transfer of the part.

Referring to fig. 4 and 5, in some embodiments, the pick head 110 may be connected to the moving seat 120, so that the pick head 110 is driven to move by the moving seat 120; of course, the pick-up head 110 and the movable base 120 may be integrally formed.

One end of the pick-up head 110 is provided with an inclined surface 111, and in a first direction parallel to the center line of the pick-up head 110, the inclined surface 111 gradually extends obliquely towards the direction of the center line, that is, along the first direction, the upstream end of the inclined surface 111 has a larger size from the center line, the upstream end is a larger end, the downstream section has a smaller size from the center line, and the downstream end is a smaller end, so that the pick-up head 110 is convenient to be introduced into the annular material 600.

Illustratively, the annular shaped charge 600 may be picked up in a vertical direction, and correspondingly, the first direction may be downward, in which case the pick head 110 may be moved downward closer to the annular shaped charge 600 and the small end of the pick head 110 passed into the inside of the annular shaped charge 600. Of course, the annular material 600 may be picked up in other directions, and the first direction may be changed accordingly, so long as the annular material 600 can be picked up, and the specific pick-up direction is not limited.

In some embodiments, one end of the material taking head 110 may be provided with a conical inclined surface 111, and of course, the inclined surface 111 may also be conical, so that the material taking head 110 can smoothly transfer into the annular material 600, and at the same time, the size of the annular material 600 may also be enlarged by the inclined surface 111, so as to facilitate material picking. Of course, the inclined surface 111 may be an intermittent circular table surface or a conical surface, or other forms, which are not particularly limited herein.

To achieve the limitation of the annular material 600, the sidewall of the material taking head 110 may be provided with an arc groove 112 extending along the circumferential direction of the material taking head 110, as shown in fig. 5, the arc groove 112 is disposed adjacent to one end of the inclined surface 111 farthest from the center line, that is, the arc groove 112 is disposed adjacent to the large end of the inclined surface 111, so that the annular material 600 supported by the large end of the inclined surface 111 may move into the arc groove 112 and limit the annular material 600 by the sidewall of the arc groove 112 to prevent the annular material 600 from being separated from the material taking head 110.

The arcuate slot 112 may be a complete circular slot, or an intermittent circular slot, etc., as examples, but may be in other forms, as well, without limitation.

To alleviate the problem that the annular material 600 is not easy to fall off when being sleeved on the inclined surface 111, in the embodiment of the present application, the inner diameter dimension D1 of the annular material 600 is greater than the distance D2 between two intersection points of the inclined surface 111 and a straight line passing through the center of the annular material 600, as shown in fig. 6. With this arrangement, it is ensured that the annular material 600 is not carried up by the inclined surface 111.

Here, considering that there is a friction force between the annular material 600 and the inclined surface 111, the magnitude of the friction force depends on the extrusion force between the annular material 600 and the inclined surface 111 and the friction coefficient, and in addition, the annular material 600 itself has gravity, so that in order to ensure that the annular material 600 can be separated from the inclined surface 111, the component force of the friction force between the annular material 600 and the inclined surface 111 in the vertical direction needs to be smaller than the gravity. Thus, in the case where the gravity of the annular material 600 and the friction coefficient of the contact surface are unchanged, the inclination angle of the inclined surface 111 with respect to the center line can be obtained, and when the component force of the friction force in the vertical direction is equal to the gravity, the minimum inclination angle is obtained, so that the specific parameters of the head 110 can be designed based on the minimum inclination angle.

In the case where the inner diameter dimension of the annular material 600 is larger than the distance between the two intersections of the straight line passing through the center of the annular material 600 and the inclined surface 111, it is possible to ensure that the angle between the inclined surface 111 and the center line is larger than the minimum inclination angle, so that it is possible to effectively prevent the annular material 600 from staying on the inclined surface 111 and moving with the head 110. Therefore, the problem that the material taking head 110 takes a plurality of annular material pieces 600 at one time can be effectively relieved, and only one annular material piece 600 positioned in the arc-shaped groove 112 is ensured to move at one time.

For example, the minimum inclination angle may be 45 °, and the included angle between the inclined surface 111 and the center line need only be greater than 45 ° and less than 90 °, and of course, the lowest inclination angle may be other degrees, such as 50 °, 60 °, and the like, which is not limited herein.

In this embodiment, the annular material 600 may be picked up by the material picking head 110, specifically, the annular material 600 may be extruded by providing the inclined surface 111, so as to deform the annular material 600, and further facilitate the annular material 600 to move toward the arc-shaped slot 112; the annular material piece 600 can be accommodated through the arc-shaped groove 112, so that the condition that the annular material piece 600 falls off in the moving process is prevented, and the annular material piece 600 can be ensured to be taken by the material taking head 110 each time; through the design to the inclination of inclined plane 111 for the internal diameter size of annular material piece 600 is greater than the distance between two intersection points of straight line and inclined plane 111 through the center of annular material piece 600, thereby can make preceding annular material piece 600 can follow inclined plane 111 and remove to arc wall 112 in, and then the unable being carried up by inclined plane 111 of annular material piece 600, thereby can effectively prevent that taking off the condition emergence of a plurality of annular material pieces 600 of stub bar 110 disposable pickup.

By means of the arrangement, a certain gap is reserved between the inner wall of the annular material piece 600 positioned in the arc-shaped groove 112 and the bottom wall of the strip-shaped groove 113, so that a tool can be conveniently transmitted in, the annular material piece 600 positioned in the arc-shaped groove 112 can be conveniently separated from the arc-shaped groove 112, and the assembly efficiency of the annular material piece 600 is improved.

Illustratively, the tool may include a plurality of support claws, each of which may be threaded into a corresponding elongated slot 113 and then each of which may be moved in a direction away from the centerline of the pick head 110, i.e., each of which may be flared so as to facilitate expanding the inner diameter of the annular material 600 so that the inner diameter of the annular material 600 is greater than the slot size of the arcuate slot 112, so that the annular material 600 may be assembled or disassembled from the arcuate slot 112.
