[0004] To achieve the above object, the utility model provides a rib cutting knife, which is installed at the end of the robotic arm of a livestock cutting robot. The rib cutting knife includes:

[0005] A knife body, which is a U-shaped structure, with two ends being parallel knife handles. Between the knife handles is a knife back. A cutting edge is arranged on the front side or both the front and back sides of the knife back. The knife back is an arc structure along the length direction.

[0006] A knife handle, which includes a connecting part and a fixing part. The connecting part is arranged at both ends of the fixing part and is respectively connected to the knife handle. And

[0007] A connecting flange, which includes a flange body. A positioning groove, a first positioning hole and a second positioning hole are arranged on the flange body. The positioning groove corresponds to the width of the knife handle. The first positioning hole is located in the positioning groove. The knife handle is installed in the positioning groove and is connected to the fixing part through the first positioning hole. The second positioning hole is connected to the end of the robotic arm for positioning.

[0008] In the above rib cutting knife, the radian of the knife body and the width of the cutting edge are adapted to the ribs to be cut.

[0050] The structural principle and working principle of the present invention will be specifically described below with reference to the accompanying drawings:

[0051] See Figures 1 - 3 , Figure 1 which is a schematic structural diagram of a livestock segmentation robot according to an embodiment of the present utility model, Figure 2 which is a schematic structural diagram of the rib cut-off mechanism 3 according to an embodiment of the present utility model, Figure 3 which is an installation schematic diagram of the rib cut-off mechanism 3 according to an embodiment of the present utility model.

[0052] During operation, the middle section of the livestock carcass is placed on the conveying device according to certain position and direction requirements and moves together with the conveyor belt. When the middle section of the livestock carcass reaches the designated position in front of the robot, the robot performs segmentation through motion tracking technology. During segmentation, the pressing claws with hooks at the front of the chain press the front end part of the middle section of the livestock carcass to fix it. The robotic arm 2 drives the rib cut-off knife 32 to move to the starting point of the knife feed. Then, according to the three-dimensional coordinates and attitude information of the pre-determined segmentation points, the robotic arm 2 drives the rib cut-off knife 32 to move quickly along each point in sequence to achieve the cutting operation, realizing the separation of the fine ribs from the streaky pork layer and dividing them into two products: fine ribs and streaky pork. Since the composition, structure, mutual position relationship, connection relationship and functions of other parts of the livestock segmentation robot and the rib cut-off mechanism 3 are all relatively mature existing technologies, they will not be elaborated here. Only the rib cut-off knife 32 of the present utility model will be described in detail below.

Among them, preferably, the length of the tool is 423 mm, the thickness of the knife body 321 is 3 mm, the width is 20 mm, the width of the cutting edge 3213 is 12 mm, the edge inclination angle is 14°, and the width of the back of the knife is 8 mm.

[0057] The present utility model can meet the requirement of automatically cutting fine ribs by the robotic arm 2. Threaded holes are provided on both sides of the knife handle 322 and the knife body 321, and the knife handle 322 can be firmly fixed, so that it will not shake during operation. Since the knife body 321 is worn during operation, the cutting edge 3213 will become blunt and need to be sharpened frequently; and the knife body 321 needs to be disinfected regularly, so the tool needs to replace the knife body 321 frequently. The rib cutting knife 32 of the present utility model can install a new knife body 321 on the knife handle 322 by screws, without replacing the knife handle 322, which simplifies the replacement operation, shortens the replacement time, and reduces the maintenance cost.
