[0039] The present invention provides a single degree of freedom mechanism for arranging rings, restoring ring shape and placing rings, such as Figures 1-8 As shown, it includes a support frame 100, a rotating disk 200 and a plurality of limiting plates 300.

[0040] A rotating shaft 400 capable of rotating relative to the supporting frame 100 is passed through the middle of the supporting frame 100 , and a plurality of first sliding grooves 103 are distributed in an annular shape on the outer side. The first sliding grooves 103 are rectangular and radially arranged relative to the rotating shaft 400 .

[0041] The rotating disk 200 is fixed on the rotating shaft 400 and is provided with a plurality of second sliding grooves 201 relative to the rotating shaft 400. The second sliding grooves 201 are arc-shaped and the curvature gradually increases from close to the rotating shaft 400 to away from the rotating shaft 400.

[0042] A plurality of limit plates 300 are distributed in a ring on the outside of the support frame 100, and each limit plate 300 corresponds to a first slide groove 103 and a second slide groove 201 respectively. A moving module is provided on the inside of the limit plate 300, and the moving module includes a first slider 301 slidingly connected to the first slide groove 103 and a second slider 302 slidingly connected to the second slide groove 201 respectively. The first slider 301 can slide on the first slide groove 103, and the second slider 302 can slide on the second slide groove 201. A supporting protrusion 303 is provided at the bottom of the limit plate 300. The ring is placed by the supporting protrusion 303 to prevent the ring from falling when the ring is transferred.

[0043] The number of the first sliding grooves 103 , the number of the second sliding grooves 201 and the number of the limiting plates 300 are the same.

[0044] The present invention provides a single-degree-of-freedom mechanism for arranging rings, restoring the shape of rings and placing rings. The mechanism has a simple structure, is easy to operate and is easy for users to use. It can quickly arrange and restore the shape of the rings and can realize rapid workstation arrangement of ring parts. The present invention is designed with a support frame 100, a rotating shaft 400, a rotating disk 200 and multiple limit plates 300 to control the movement of the limit plates 300. When the limit plates 300 are fully extended, the multiple limit plates 300 can limit the shape of the rings, restore the shape of the rings, and ensure the stability of the rings during the arrangement and placement process. The present invention can allow the limit plates 300 to accommodate several rings from bottom to top at the same time, thereby improving the capacity and efficiency of the mechanism and greatly shortening the time for arranging and placing the rings.

[0045] The present invention provides a single-degree-of-freedom tidying ring, ring shape restoration and ring placement mechanism, and a method of using the mechanism includes the following steps:

[0046] Step 1: Rotate the rotating shaft 400 to open the multiple fully limiting plates 300;

[0047] Step 2: Place multiple rings from bottom to top on the outside of multiple limiting plates 300 and on the supporting protrusions 303 to stack the rings, sort out the disordered rings, and define the shape of the rings with the limiting plates 300 to restore the ring shape;

[0048] Step 3: Lift the rotating shaft 400 and transfer it to the designated position;

[0049] Step 4: Rotate the rotating shaft 400 in the opposite direction to retract the plurality of limiting plates 300 so that the plurality of rings are placed at designated positions.

[0050] In the present invention, in order to maintain a certain stability of the mechanism, as Figure 1 and Figure 5 As shown, the support frame 100 includes a top plate 101 and a bottom plate 102 which are arranged at a certain distance from each other. The top plate 101 and the bottom plate 102 are connected by a plurality of annularly distributed support columns 104. The top ends of the support columns 104 are fixed to the top plate 101, and the bottom ends of the support columns 104 are fixed to the bottom plate 102. A plurality of first slide grooves 103 are annularly distributed on the outer sides of the top plate 101 and the bottom plate 102.

[0051] In the present invention, in order to further maintain a certain stability of the mechanism, as Figures 1-8As shown, the two rotating disks 200 are fixed on the rotating shaft 400 at a certain distance, and the two rotating disks 200 are arranged in the support frame 100, one of the rotating disks 200 is arranged below the top plate 101, and the other rotating disk 200 is arranged above the bottom plate 102. The two rotating disks 200 are driven to move simultaneously by rotating the rotating shaft 400, and two groups of moving modules are provided on the inner side of the limiting plate 300, one group of moving modules corresponds to the top plate 101 and one rotating disk 200, and the other moving module corresponds to the bottom plate 102 and the other rotating disk 200. In the moving module, the first slider 301 can slide on the first slide groove 103 on the top plate 101 or the bottom plate 102, and the second slider 302 can slide on the second slide groove 201 on the rotating disk 200.

[0052] Specifically, the moving module includes a fixed plate 305 , a first slider 301 and a second slider 302 . The fixed plate 305 is fixed inside the limiting plate 300 . The first slider 301 is located at the top of the fixed plate 305 , and the second slider 302 is located at the bottom of the fixed plate 305 .

[0053] The present invention provides a single-degree-of-freedom arranging ring, ring shape restoration and ring placement mechanism, which can arrange rings of various shapes. According to the shape of the ring, by changing the length of the first slide groove 103 and the second slide groove 201, the number of the first slide groove 103, the second slide groove 201 and the limit plate 300, and the cross-sectional shape of the limit plate 300, rings of different shapes can be arranged.

[0054] For example, in one embodiment of the present invention, Figures 1-4 As shown, when the ring is arc-shaped, the cross-section of the limit plate 300 is arc-shaped, and the number of the first slide groove 103, the second slide groove 201 and the limit plate 300 is 3. The top plate 101 and the bottom plate 102 of the support frame 100 are both triangular plate structures. The three first slide grooves 103 are respectively arranged on the three sides of the triangular plate structure. The angle between two adjacent first slide grooves 103 is 120 degrees, and the three limit plates 300 are respectively arranged on the outside of the three first slide grooves 103.

[0055] In one embodiment of the present invention, Figure 5-Figure 8 As shown, when the ring is a regular polygon, the number of the first sliding grooves 103, the second sliding grooves 201 and the limiting plates 300 is the same as the number of the sides of the polygon, and the cross section of the limiting plate 300 is a rectangle.

[0056] In the present invention, in order to fully restore the shape of the ring, the distance from the limiting plate 300 to the rotating shaft 400 is determined according to the inner size of the ring.

[0057] In the present invention, when the ring is a symmetrical structure, the plurality of first chutes 103 are evenly distributed in a ring shape on the support frame 100 about the rotating shaft 400 , and the plurality of second chutes 201 are centrally symmetrically distributed relative to the rotating disk 200 .

[0058] For example, Figure 2 As shown, when the ring is arc-shaped, the distance from the limiting plate 300 to the rotating shaft 400 is the inner radius of the ring.

[0059] In the present invention, in order to facilitate the rotation of the rotating shaft 400, a handle 401 is provided on the top of the rotating shaft 400.

[0060] In the present invention, Figure 3 and Figure 7 As shown, in order to facilitate the placement of the ring, an inward-bent arc hook 304 is provided on the top of the limiting plate 300. The ring can slide to the outside of the limiting plate 300 through the arc hook 304, making it easier to place the ring from top to bottom and ensuring that the limiting plate 300 will not scrape the ring during this process.

[0061] Specifically, in the present invention, a plurality of arc-shaped hooks 304 are provided on the top of each limiting plate 300 and are evenly distributed at a certain distance.

[0062] In the present invention, the support frame 100 is rotatably connected to the rotating shaft 400 via a retaining bearing.

[0063] In the present invention, Figure 4 and Figure 8 As shown, a locking protrusion 202 is provided in the second chute 201. The locking protrusion 202 is located at the end of the second chute 201 away from the rotating shaft 400. The locking protrusion 202 is arc-shaped and serves to lock the limit plate 300. When locked, the limit plate 300 can only be moved by pulling the rotating shaft 400. The provision of the locking protrusion 202 prevents the limit plate 300 from rotating when the entire mechanism is lifted, which could cause the ring to fall off.

[0064] In the present invention, Figure 1 and Figure 5 As shown, the support protrusion 303 is a downwardly inclined slope, which not only ensures that the ring will not fall off from under the entire mechanism when placing or transferring the ring, but also when multiple limit plates 300 are retracted to place multiple rings in specified positions, the slope will not affect the placed rings.

[0065] In the present invention, Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, the second slide groove 201 is a through groove structure, and the second slider 302 is rotatably connected to the bottom of the fixed plate 305 on the limit plate 300. The second slider 302 is a cylindrical structure with a smooth outer surface, which converts sliding friction into rolling friction, greatly reducing friction. For example, the second slider 302 can be set as a bearing, and the inner ring of the bearing is fixed to the bottom of the fixed plate 305. The outer ring of the bearing can rotate relative to the inner ring of the bearing. Baffles are provided at both ends of the bearing to prevent the bearing from falling off from the second slide groove 201.

[0066] Correspondingly, the first sliding block 301 is fixed on the top of the fixing plate 305 .

[0067] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
