[0036] like Figures 1 to 5 As shown, the present application provides an 8-shaped tendon grabbing device for grabbing and placing 8-shaped tendons and Figure 5The butterfly tendon 5 composed of 8-shaped tendons is shown. The 8-shaped tendon grasping device includes a clamping jaw assembly 1, a reversing assembly 2 and a moving assembly 3. The two groups of clamping jaw assemblies 1 are arranged at intervals. Each clamping jaw assembly 1 includes a clamping drive 11. The output end of the clamping drive 11 is provided with two clamping jaws 12. The clamping drive 11 drives the two clamping jaws 12 to move closer to or away from each other; the reversing assembly 2 includes a flipping drive 21 and a rotating drive 22. The two groups of clamping jaw assemblies 1 are provided at the output end of the flipping drive 21. The flipping drive 21 drives the clamping jaw assembly 1 to flip; the flipping drive 21 is provided at the output end of the rotating drive 22. The driving member 22 drives the clamping jaw assembly 1 to rotate; the moving assembly 3 includes a first driving member 31, a second driving member 32 and a third driving member 33. The rotating driving member 22 is arranged at the output end of the first driving member 31, and the first driving member 31 drives the rotating driving member 22 to move along the first direction; the first driving member 31 is arranged at the output end of the second driving member 32, and the second driving member 32 drives the first driving member 31 to move along the second direction; the second driving member 32 is arranged at the output end of the third driving member 33, and the third driving member 33 drives the second driving member 32 to move along the third direction; the first direction, the second direction and the third direction are perpendicular to each other.

[0037] In the current embodiment, the third direction refers to the vertical direction ( Figure 1 The first direction and the second direction refer to the horizontal direction perpendicular to the vertical direction ( Figure 1 in the X and Y directions).

[0038] When taking and placing the 8-shaped rib or butterfly rib 5, the first driving member 31, the second driving member 32 and the third driving member 33 drive the clamping jaw assembly 1 to be placed in the placement position of the 8-shaped rib or the butterfly rib 5, so that the clamping jaw 12 in the clamping jaw assembly 1 corresponds to the two annular positions of the 8-shaped rib, and then the clamping driving member 11 drives the clamping jaws 12 to approach each other to clamp the two annular positions in the 8-shaped rib; after being adjusted to the placement position again by the first driving member 31, the second driving member 32 and the third driving member 33, the rotating driving member 22 and the flipping driving member 21 rotate and / or flip it according to the direction in which the 8-shaped rib or butterfly rib 5 needs to be placed, and then the clamping driving member 11 drives the clamping jaw 12 away, so that the 8-shaped rib or butterfly rib 5 can be placed according to different positions, reducing labor intensity and improving production efficiency.

[0039] For example, the first driving member 31 , the second driving member 32 and the third driving member 33 may be, but are not limited to, linear modules.

[0040] like Figure 2 and Figure 3As shown, in order to be able to install the clamping jaw assembly 1 on the output end of the flipping drive 21, the 8-shaped rib grasping device also includes a mounting seat 4, and two groups of clamping jaw assemblies 1 are arranged on the mounting seat 4 at intervals, so as to be able to clamp the two annular positions of the 8-shaped rib, and the mounting seat 4 is arranged at the output end of the flipping drive 21. The flipping drive 21 drives the mounting seat 4 to flip, thereby driving the clamping jaw assembly 1 to flip. Specifically, the clamping jaw assembly 1 includes a clamping jaw seat 13, which is detachably connected to the mounting seat 4, and the clamping drive 11 is fixed to the clamping jaw seat 13. Exemplarily, the clamping jaw seat 13 and the mounting seat 4 can be connected to each other by bolts, but is not limited to bolts. In the current embodiment, the clamping drive 11 adopts a single-head cylinder, and the output end of the single-head cylinder is connected to a connecting rod group 14, so that the two opposite clamping jaws 12 are connected by the connecting rod group 14.

[0041] like Figure 2 As shown, specifically, the connecting rod assembly 14 has two first rods 141, the first ends of the two first rods 141 are hinged to the clamping jaw seat 13 at intervals, and the two clamping jaws 12 are respectively connected to the second ends of the two first rods 141, so that the two clamping jaws 12 are opposite each other. The connecting rod assembly 14 also includes a second rod 142 and a third rod 143, wherein the second rod 142 is disposed at the output end of the clamping drive 11, and the clamping drive 11 drives the second rod 142 toward or away from the clamping jaw seat 13. Both ends of the second rod 142 are hinged to the first end of the third rod 143, and the second end of the third rod 143 is hinged between the first end of the first rod 141 and the second end of the first rod 141. In the current embodiment, both ends of each second rod 142 are hinged to two third rods 143, the first end of the third rod 143 is hinged to opposite sides of the second rod 142, and the second end of the third rod 143 is hinged to opposite sides of the first rod 141. Thus, through the above-mentioned connecting rod group 14, when the clamping driver 11 drives the second rod 142 away from the clamping jaw seat 13, the two opposing clamping jaws 12 move away from each other; when the clamping driver 11 drives the second rod 142 toward the clamping jaw seat 13, the two opposing clamping jaws 12 move toward each other to clamp the 8-shaped rib. Furthermore, to ensure the stability of the clamping jaws 12, each clamping driver 11 corresponds to two connecting rod groups 14, and the output end of the clamping driver 11 is connected to the two second rods 142, driving the two second rods 142 to move synchronously, that is, the two first rods 141 are connected to the clamping jaws 12. In some alternative embodiments, the clamping driver 11 can adopt a double-headed cylinder, and the two clamping jaws 12 are respectively arranged at the output end of the double-headed cylinder.

[0042] In some embodiments, the clamping jaw 12 is provided with a clamping groove 121, and when the clamping jaw 12 clamps the 8-shaped rib, it is embedded in the clamping groove 121 to ensure stable clamping. It is understood that an anti-slip layer can also be provided in the clamping groove 121 to further improve stability.

[0043] like Figures 2 to 4As shown, in some embodiments, the flipping drive member 21 includes a linear cylinder 211, which is arranged at the output end of the rotating drive member 22, and the rotating drive member 22 drives the linear cylinder 211 to rotate. Two opposite first mounting plates 212 are provided on the linear cylinder 211, and a gear 214 is provided between the two first mounting plates 212. The gear 214 is connected to the first mounting plate 212 through a rotating shaft, and a rack 213 is provided at the output end of the linear cylinder 211. The rack 213 is engaged with the gear 214, and a second mounting plate 215 is fixed on the side of the gear 214 away from the rack 213. The mounting seat 4 is detachably connected to the second mounting plate 215, so that when the linear cylinder 211 drives the rack 213 to move, it can drive the gear 214 to rotate, and then drive the mounting seat 4 to flip. Furthermore, to ensure meshing of the rack 213 and the gear 214, a push rod 216 is provided between the first mounting plate 212. The push rod 216 pushes against the side of the rack 213 facing away from the gear 214 to prevent the rack 213 from disengaging from the gear 214. The flip drive mode in which the rack 213 and the gear 214 are meshed can make the flipping more precise.

[0044] In the current embodiment, the rotary driving member 22 may be, but is not limited to, a rotary cylinder.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
