[0037] It should be noted that the connecting plate 10 is a plate structure, the connecting cylinder 20 is a cylindrical structure, and the sliding block 30 can be slidably connected to the connecting plate 10 through a structure such as a sliding groove, for example, four sliding blocks 30 are slidably connected to one connecting plate 10, one connecting plate 10, one connecting cylinder 20 and four sliding blocks 30 constitute a structural unit of the rope-driven parallel robot end platform, as Figure 2As shown, when two structural units are connected to form a structural configuration of the rope-driven parallel robot end platform, two connecting barrels 20 are connected, and the lower connecting plate 10 is used to connect the load 40, and as shown Figure 3 As shown, the rope-driven parallel robot can include a frame 01, a driving mechanism 90 is arranged on the frame 01, and eight ropes 50 are respectively connected to eight sliders 30 in two structural units and correspondingly connected to the driving mechanism 90; further, as shown Figure 4 As shown, two structural units can be respectively connected at both ends of a load structure, such as a receiving plate 70 for receiving a load, to form another structural configuration of the end platform, and as shown Figure 5 As shown, eight ropes 50 can also be used to connect eight sliders 30 in two structural units to drive and control the end platform. In addition, for the planning of the motion trajectory and path of the rope-driven parallel robot end platform, the shape, mass, and center of mass of the actual load 40, as well as the requirements of the task, can be planned, and specifically, the spatial position of the slider 30 relative to the connecting plate 10, that is, the knot point of the driving rope 50 and the end platform, and the position of the structural unit connecting the load 40, and the structural configuration of the end platform formed by the combination of the structural units, can be calculated in advance by computer algorithm combined with spatial kinematics model, and after adjusting and fixing according to the calculation results, the operation is more accurate and reliable. More specifically, by slidingly connecting a plurality of sliders 30, such as four, on the connecting plate 10, that is, the end platform connected and driven by eight ropes 50 has more degrees of freedom, the motion trajectory is more abundant, the control is more agile and accurate, and thus it can adapt to more types of loads 40 and task requirements.
[0038] In this embodiment, the rope-driven parallel robot end platform provided by the present embodiment can be applied to a rope-driven parallel robot, and by setting the structural form of the connecting plate 10 connecting the connecting barrel 20, one connecting plate 10 and one connecting barrel 20 can form a structural unit, and different end platform structural configurations can be formed by the combination and connection of structural units, for example, as shown Figure 2 As shown, two structural units are connected, which can be connected by two connecting barrels 20, and then one connecting plate 10 is used to connect the load 40, or as shown Figure 4As shown, two structural units are connected to the load 40, such as being connected at opposite ends of the load 40, etc. The load 40 can be connected through the connecting barrel 20, which can adapt to different requirements of different masses, mass centers and shapes of different loads 40, etc. Meanwhile, a plurality of sliders 30 are slidably connected to the connecting plate 10, and are connected and positioned through the first connecting part 121 and the second connecting part 31. In use, the positions of the sliders 30 relative to the connecting plate 10 can be adjusted according to actual needs, that is, the positions of the plurality of ropes 50 and the knotting points of the end platform are adjusted, different motion trajectories and paths can be adapted and planned, and the combination forms of the spatial positions of the knotting points of the ropes 50 are further expanded through different combinations between the above structural units, thereby expanding the application range of the end platform of the rope-driven parallel robot, so that different characteristics of different loads 40 and a variety of operation requirements of different operation tasks can be adapted, and the use is convenient. The cost waste caused by the need to redesign and manufacture the end platform when dealing with different operation tasks and different loads 40 is avoided, resources are saved, and operation efficiency is improved.
[0039] Optionally, as shown in Figure 2 and Figure 3 The end platform of the rope-driven parallel robot further comprises a receiving frame 60, two ends of each of the two connecting barrels 20 away from the connecting plate 10 are connected to each other, and the two connecting plates 10 are located at opposite ends of the two connecting barrels 20. The receiving frame 60 is connected to the lower connecting plate 10 and is used for receiving the load 40.
[0040] Specifically, the receiving frame 60 comprises a connecting column and a flat plate. The connecting column is used for connecting the lower connecting plate 10 and is connected to the lower end of the connecting plate 10. The flat plate is connected to the lower end of the connecting column and is used for receiving the load 40. The end platform with this structure is suitable for receiving loads 40 with small mass or small shape, and the two groups of sliders 30, that is, the two groups of sliders 30 slidably connected to the two connecting plates 10 have initial positions at the upper and lower ends and have more degrees of freedom for planning and adjusting.
[0041] In this embodiment, the receiving frame 60 is provided, and the two structural units are connected to each other, that is, the two connecting barrels 20 are connected to each other to form the end platform, which has two groups of sliders 30 and is located at, for example, the upper and lower ends, so as to form more planning and combinations of knotting point positions, thereby enriching the motion trajectories of the end platform of the rope-driven parallel robot and expanding the application range. Meanwhile, the receiving frame 60 is connected to the lower connecting plate 10, so as to stably receive the load 40 and run more stably.
[0042] Optionally, as shown in Figure 3 and Figure 4As shown, the rope-driven parallel robot end platform further comprises a receiving plate 70, two connection barrels 20 are connected to opposite ends of the receiving plate 70 respectively, and the connection plate 10 and the receiving plate 70 are located at opposite ends of the connection barrel 20 respectively, and the receiving plate 70 is used for receiving the load 40.
[0043] Specifically, the receiving plate 70 is a plate structure, and the positions of the two connection barrels 20 connected to the receiving plate 70 can be adjusted according to actual needs, and it should be noted that the specific structures of the above-mentioned receiving frame 60 and the receiving plate 70 can be adaptively designed according to different shapes, masses and mass center positions of the actual load 40, and the specific structures are not limited here.
[0044] In this embodiment, by arranging the receiving plate 70 and connecting the two connection barrels 20 to opposite ends of the receiving plate 70, on the one hand, the receiving plate 70 can be stably connected, that is, the load 40 is stably connected, and on the other hand, the two groups of sliders 30 on the two connection plates 10 are located at opposite ends of the receiving plate 70 at the same time, so that the ropes 50 do not interfere with each other, which is more convenient for planning the motion trajectory of the load 40, and also enriches the types of motion trajectory of the load 40, and further expands the application range of the rope-driven parallel robot end platform.
[0045] Optionally, as shown in Figure 1 , Figure 6 and Figure 7 , the connection plate 10 comprises a main plate 11, opposite four corners of the main plate 11 extend in a direction away from the main plate 11 and have a sub-plate 12 respectively, the slider 30 is slidingly connected to the sub-plate 12, and the first connecting part 121 is arranged on the sub-plate 12.
[0046] Specifically, the main plate 11 is a circular plate structure and is used for being connected with the connection barrel 20, which is reasonable in structure and stable in connection, and the sub-plate 12 is a long strip plate structure and is arranged in pairs of symmetry and integrally formed with the main plate 11, which is more firm in structure.
[0047] In this embodiment, by arranging the connection plate 10 in the form of the main plate 11 and the four sub-plates 12, on the one hand, the opposite four sub-plates 12 can more conveniently slidingly connect the sliders 30, and can slidingly adjust the relative positions on the sub-plates 12, that is, adjust the positions of the rope connecting points, so that the adjustment of the rope connecting points of the rope-driven parallel robot end platform is more regular and does not interfere with each other, which is convenient for planning and calculating the overall motion trajectory, and on the other hand, the four sub-plates 12 are arranged in the direction away from the main plate 11, so that the overall structure of the connection plate 10 is more symmetrical and stable, that is, the connection of the load 40 is more stable and reliable.
[0048] Optionally, as shown inFigure 1 , Figure 6 and Figure 7 As shown, a slide rail 122 is provided on the sub-plate 12 along its extension direction. One end of the slider 30 is provided with a sliding part adapted to the slide rail 122. The other end of the slider 30 is provided with a third connecting part 32, which is used to connect with the rope 50.
[0049] Specifically, the slide rail 122 can be a long groove structure, and correspondingly, the sliding part on the slider 30 can be a long protrusion structure. Of course, it should be noted that the surface connecting the slider 30 and the slide rail 122 can be a smooth plane as the sliding part to achieve a sliding connection, and no specific limitation is made here. At the same time, the third connecting part 32 can be a connecting post, connecting ring, or other structures, used to connect the rope 50 and serve as a knotting point. Its specific structure is also not specifically limited here, as long as it can stably connect the rope 50.
[0050] In this embodiment, by setting a slide rail 122 on the sub-plate 12, the slider 30 can be connected more stably. Furthermore, a sliding part adapted to the slide rail 122 is set on the slider 30, making the structure fit more tightly, the adjustment smoother, and the adjustment path more precise. In addition, by setting a third connecting part 32 on the slider 30, the rope 50 can be connected, which means that the adjustment of the knot point position is more regular and facilitates the advance calculation and planning of the movement trajectory.
[0051] Optionally, such as Figure 1 , Figure 6 , Figure 7 and Figure 10 As shown, the end effector platform of the rope-driven parallel robot also includes a positioning component. The first connecting part 121 is an elongated hole structure, and the second connecting part 31 is a hole structure. The positioning component is used to connect with the first connecting part 121 and the second connecting part 31.
[0052] Specifically, the positioning component can be a threaded component, not shown in the figure, such as a structure using a screw and a nut. The screw passes through the hole structure of the second connecting part 31 on the slider 30, and then through the elongated hole structure of the first connecting part 121 on the connecting plate 10. After that, the nut is tightened to fix the positioning, that is, the relative position of the slider 30 and the connecting plate 10 is fixed. Furthermore, the length direction of the elongated hole of the first connecting part 121 is consistent with the direction of the slide rail 122, which facilitates position adjustment and precise positioning.
[0053] In the embodiment, the positioning member is arranged to stably connect and position the sliding block 30 and the connecting plate 10, that is, to stably limit the position of the knot tying point, and the overall structure is more stable and reliable. Meanwhile, the first connecting portion 121 on the connecting plate 10 is arranged as a long hole structure, and the second connecting portion 31 on the sliding block 30 is arranged as a hole structure. On one hand, the positioning member is more convenient to connect and fix. On the other hand, when the position of the sliding block 30 is adjusted, the sliding block 30 can be adjusted and positioned along the length direction of the long hole, and the adjustment is more accurate and reliable.
[0054] Optionally, as shown in Figure 1 、 Figure 8 and Figure 9 , one end of the connecting cylinder 20 is provided with a first flange plate 21, and the other end is provided with a second flange plate 22. The first flange plate 21 is connected with the connecting plate 10, and the second flange plate 22 is used to be connected with the load 40, or the two second flange plates 22 on the two connecting cylinders 20 are used to be connected with each other.
[0055] Specifically, the first flange plate 21 and the second flange plate 22 are both extended outward from the cylinder wall of the connecting cylinder 20, and a plurality of connecting holes are formed on them, which facilitates connection and positioning, and the integrated structure is more firm and reliable.
[0056] In the embodiment, the first flange plate 21 and the second flange plate 22 are arranged at opposite ends of the connecting cylinder 20, which is more convenient and stable to connect the load 40 and the connecting plate 10, or to connect the two connecting cylinders 20 with each other. It should be noted that when the end platform of the rope-driven parallel robot is a structure in which two structural units are connected with each other as shown in Figure 2 and 3 , the two second flange plates 22 of the two connecting cylinders 20 are connected with each other. When the end platform of the rope-driven parallel robot is a structure in which two structural units are connected at opposite ends of the load 40 as shown in Figure 4 and 5 , the two second flange plates 22 of the two connecting cylinders 20 are connected with, for example, the receiving plate 70. Meanwhile, the structures of the first flange plate 21 and the second flange plate 22 are more convenient for connection and positioning after the rotation angle between the structural members is adjusted, so that the overall adjustable range is further expanded, the application range is wider, and the overall work efficiency is further improved.
[0057] Optionally, as shown in Figure 1 、 Figure 8 and Figure 9As shown, the second flange plate 22 is provided with arc-shaped holes 221, and the arc shape of the arc-shaped holes 221 is arranged along the circumference of the second flange plate 22. The arc-shaped holes 221 are used to connect the load 40 or another second flange plate 22 through screw cooperation.
[0058] Specifically, the number of arc-shaped holes 221 can be multiple, and the arc-shaped holes 221 are arranged along the circumference of the second flange plate 22. The arc-shaped holes 221 are long holes with arc-shaped long edges, that is, the long edges are arc-shaped edges, and the arc-shaped edges are circular arc edges. The center of the circular arc is concentric with the center of the connecting cylinder 20 and the second flange plate 22, which facilitates rotation adjustment.
[0059] In this embodiment, by providing arc-shaped holes 221 on the second flange plate 22, the arc-shaped holes 221 and the screw cooperation can be used to connect the load 40 or another second flange plate 22. Specifically, when the end platform of the rope-driven parallel robot is a structure as shown in Figure 2 and 3 , two structure units are connected in opposite directions, and the two second flange plates 22 of the two connecting cylinders 20 are connected through the arc-shaped holes 221 and the screw cooperation. When the end platform of the rope-driven parallel robot is a structure as shown in Figure 4 and 5 , two structure units are connected at opposite ends of the load 40, such as a receiving plate 70 that receives the load 40. The two second flange plates 22 of the two connecting cylinders 20 are connected through the arc-shaped holes 221 and the screw cooperation, such as the receiving plate 70. By rotating the connecting cylinder 20 and adjusting the connection position of the screw relative to the arc-shaped hole 221, the connecting plate 10 can be adjusted in rotation relative to the load 40, that is, the connection point is adjusted in rotation relative to the load 40. This achieves angle adjustment, further enriches the adjustment range of the movement trajectory and action path of the load 40, and makes adjustment convenient and fast, further improving the overall work efficiency.
[0060] Alternatively, as shown in Figure 1 , Figure 8 , Figure 9 and Figure 11 , the rope-driven parallel robot end platform further comprises a positioning shaft 80. The connecting plate 10 is provided with a positioning hole 111, and the connecting cylinder 20 is provided with a positioning cylinder 23 along its axis. The positioning hole 111 and the positioning cylinder 23 are matched with the positioning shaft 80. The positioning shaft 80 is arranged in the positioning hole 111 and the positioning cylinder 23. The connecting cylinder 20 is provided with a support plate 24 connected between the cylinder wall of the connecting cylinder 20 and the cylinder wall of the positioning cylinder 23.
[0061] Specifically, the positioning hole 111 is arranged on the connecting plate 10, as shown inFigure 6 and Figure 7 As shown in the figure, the positioning hole is opened at the center position of the main plate 11 of the connecting plate 10, that is, the center part of the connecting plate 10, which is more accurate in positioning and convenient for rotation adjustment, and meanwhile, the support plates 24 provided in the connecting cylinder 20 are vertical plate structures provided along the axial direction, and there are four of them, which are symmetrically and evenly distributed, and the structure is more stable and firm, and preferably, the cylinder wall of the connecting cylinder 20, the support plates 24 and the positioning cylinder 23 are integrally formed.
[0062] In the embodiment, by providing the positioning shaft 80, and opening the corresponding positioning hole 111 on the connecting plate 10, and providing the corresponding positioning cylinder 23 in the connecting cylinder 20, when the connecting plate 10 is connected with the connecting cylinder 20, the positioning shaft 80 can be further used for axial positioning, and the connection precision is higher, and meanwhile, when the angle is adjusted, the positioning shaft 80 can also be used as the rotation center shaft for positioning during the adjustment process, so that the rotation adjustment is more accurate and reliable, and by providing the support plates 24 to support, position, connect and fix the positioning cylinder 23 in the connecting cylinder 20, the stability of the overall structure is further improved.
[0063] In addition, as shown in the figures, Figure 3 and Figure 5 Another embodiment of the present application provides a rope-driven parallel robot, which comprises the above-mentioned rope-driven parallel robot end platform.
