[0028] See also Figure 1 An embodiment of the present application provides a robot load device 100 and a robot 200. The robot load device 100 can be applied to the robot 200 and is used to adjust the weight and center of mass position of the load of the robot 200 according to the test requirements of the robot 200.
[0029] This specification does not limit the specific type of the robot 200. For example, the robot 200 may be an industrial robot arm robot or a collaborative robot. In this embodiment, the robot 200 is an industrial robot. The robot 200 may include the robot load device 100, a body 201, and a load end 203. The load end 203 is connected to the body 201. The robot load device 100 is detachably connected to the load end 203, for example, detachably connected to the load end 203 via a flange.
[0030] Please also see Figure 1 and Figure 2 In this embodiment, the robot loading device 100 may include a mounting seat 10, at least one load plate 20, and a locking member 30. The mounting seat 10 is connected to the load end 203, and the mounting seat 10 may include a mounting member 12 and a rotating shaft 14, and the rotating shaft 14 is connected to the mounting member 12. The load plate 20 is rotatably connected to the mounting member 12 through the rotating shaft 14, and the load plate 20 has a geometric center G, and the geometric center G is spaced apart from the rotating shaft 14. The locking member 30 is disposed between the rotating shaft 14 and the load plate 20, and is used to lock the load plate 20 to the mounting seat 10.
[0031] The above-mentioned “geometric center” is understood to be the most central position of an object with a certain symmetry. In this embodiment, the geometric center is the most central position of the load disk 20. If the load disk 20 is a disk, the load center is located on the axis of the load disk 20. If the load disk 20 is a sphere, the load center is located at the center of the sphere.
[0032] In the robot loading device 100 provided in the embodiment of the present application, the number of load discs 20 is adjustable. When in use, the load discs 20 can be increased according to the test requirements of the robot 200 to make it close to the required load weight. The load disc 20 can rotate around the rotating shaft 14 relative to the mounting member 12, and the geometric center G of the load disc 20 is spaced from the rotating shaft 14. The load disc 20 is eccentrically arranged, and when the load disc 20 rotates relative to the mounting member 12, the position of its center of mass will change. After the load disc 20 is installed, the center of mass can be adjusted by rotation. After the adjustment is completed, it is fixed to the mounting seat 10 by the locking member 30, which can ensure stability during the test. The inertia and center of mass position of the robot loading device 100 provided in the embodiment of the present application can be adjusted, which can quickly meet the load adjustment requirements, is suitable for load testing of various robots 200, improves test efficiency, and reduces test costs.
[0033] In this application, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be internal communication between two elements, or it can be only surface contact. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0034] In this embodiment, the robot load device 100 may further include a connecting member 40, which is connected to the load end 203 of the robot 200. The connecting member 40 is movably connected to the mounting member 12, and the mounting member 12 can move relative to the connecting member 40 along the first direction X. The load plate 20 is connected to the mounting member 12, and the center of mass of the entire robot load device 100 can be changed when the mounting member 12 moves relative to the connecting member 40 along the first direction X. The cooperation between the connecting member 40 and the mounting member 12 increases the direction of center of mass adjustment and increases the applicable range of the robot load device 100.
[0035] The connecting member 40 may include a translational matching portion 41 and a rotating disk 43, wherein the translational matching portion 41 is connected between the rotating disk 43 and the mounting member 12. The rotating disk 43 is used to be connected to the load end 203, and the rotating disk 43 is generally in the shape of a disk. The rotating disk 43 is provided with a plurality of positioning portions 432, and the plurality of positioning portions 432 are used to be detachably connected to the load end of the robot 203, and the plurality of positioning portions 432 are arranged around the axis of the rotating disk 43.
[0036] When the rotating disk 43 is installed, it can be connected to the load end 203 through a plurality of positioning parts 432. If the position of the center of mass needs to be adjusted, the rotating disk 43 can be first removed from the load end 203, and the rotating disk 43 can be rotated around the axis of the rotating disk 43 to rotate relative to the load end 203, and then the rotating disk 43 can be fixed to the load end 203 again. When the rotating disk 43 rotates relative to the load end 203, the load disk 20 is driven to rotate together through the translation matching part 41 to achieve the adjustment of the center of mass position.
[0037] This specification does not limit the specific structure of the positioning portion 432. The positioning portion 432 can be a mounting bolt installed on the rotating disk 43, or the positioning portion 432 can also be a positioning hole formed on the rotating disk 43. In this embodiment, the positioning portion 432 is a positioning groove formed on the rotating disk 43, and multiple positioning grooves are evenly spaced around the axis of the rotating disk 43. As an example, a flange can be provided on the load end 203, and the rotating disk 43 can be connected to the flange on the load end 203 by fasteners such as screws, bolts, and pins. There can be multiple fasteners, and multiple fasteners are inserted into multiple positioning grooves and connected to the flange on the load end 203. In other embodiments, the positioning portion 432 is a waist-shaped groove, and the shapes and sizes of multiple positioning portions 432 are the same, and the angles of the central angles corresponding to the two ends of each positioning portion 432 are equal.
[0038] In order to facilitate the control of the rotation angle of the rotating disk 43 relative to the load end 203, in this embodiment, the load end 203 may be provided with a reference scale, which may be a groove opened on the flange of the load end 203, the groove extending along the radial direction of the rotating disk 43, and the reference scale may be marked as 0. The rotating disk 43 is provided with a first indexing groove 434, and the first indexing groove 434 is arranged around the axis of the rotating disk 43. The first indexing groove 434 is suitable for cooperating with the reference scale of the load end 203 to represent the rotation angle of the rotating disk 43 relative to the load end 203. When the rotating disk 43 rotates to different positions relative to the load end 203, the first indexing groove 434 corresponding to the reference scale of the load end 203 is different.
[0039] The first indexing groove 434 may include a plurality of grooves radially opened on the rotating disk 43. The present specification does not limit the specific arrangement of the first indexing groove 434. For example, the angle between two adjacent grooves of the first indexing groove 434 is 10°. The rotating disk 43 may also be provided with a digital mark corresponding to the first indexing groove 434 for easy identification. For example, the digital mark on the rotating disk 43 may include 0, 10, 20, 30, 330, 340, 350, etc. Before use, the rotating disk 43 is in the initial position, and the first indexing groove 434 marked as 0 on the rotating disk 43 is aligned with the reference scale of the load end 203. When adjusting the center of mass, first calculate the value to be adjusted, then rotate the rotating disk 43 relative to the load end 203 by a predetermined angle, and then fix the rotating disk 43 to the load end 203 through the positioning portion 432.
[0040] In order to facilitate observation of the first dividing groove 434, in the present embodiment, the first dividing groove 434 is formed on the end surface of the rotating disk 43 at one end close to the translational matching portion 41, and extends to the peripheral wall of the rotating disk 43, so that the operator can clearly distinguish the relative position between the first dividing groove 434 and the reference scale of the load end 203.
[0041] Please also see Figure 2 and Figure 3 The translational matching portion 41 is fixedly connected to the rotating disk 43 and is roughly in the shape of a cube. In order to facilitate the connection between the rotating disk 43 and the load end 203, in this embodiment, the connecting member 40 may further include a connecting portion 45, which is connected between the translational matching portion 41 and the rotating disk 43. The connecting portion 45 is roughly in the shape of a cylinder, the axis of the connecting portion 45 coincides with the axis of the rotating disk 43, and the outer diameter of the connecting portion 45 is smaller than the outer diameter of the rotating disk 43, so that fasteners such as bolts can be inserted from the positioning portion 432 and connected to the load end 203.
[0042] In this embodiment, the translational matching part 41 is slidably connected to the mounting member 12. This specification does not limit the direction of relative sliding between the translational matching part 41 and the mounting member 12. For example, the direction of relative sliding between the translational matching part 41 and the mounting member 12 is parallel to the first direction X, or intersects with the first direction X (for example, perpendicular). In this embodiment, the translational matching part 41 slides along the first direction X relative to the mounting member 12. The translational matching part 41 has a first marking surface 412, and the mounting member 12 has a second marking surface 121. The first marking surface 412 and the second marking surface 121 are flush. The first marking surface 412 is provided with a first scale 4121, and the second marking surface 121 is provided with a second scale 1212. The first scale 4121 and the second scale 1212 are used for matching readings. The first scale 4121 is arranged along the first direction X, and the second scale 1212 is arranged along the first direction X. When the translational matching portion 41 and the mounting member 12 move relatively to different positions, the readings of the first scale 4121 and the second scale 1212 are different.
[0043] The mounting member 12 moves relative to the translational matching portion 41 along the first direction X, which can change the center of mass position of the robot load device 100. The first scale 4121 and the second scale 1212 facilitate the operator to accurately adjust the center of mass position, thereby improving the convenience and applicability of the robot load device 100. When adjusting the center of mass, the value to be adjusted is first calculated, and then the mounting member 12 is moved relative to the translational matching portion 41 along the first direction X by a predetermined distance.
[0044] In this embodiment, the first marking surface 412 can be understood as a side surface of the translation matching portion 41, and the second marking surface 121 is a side surface of the mounting member 12. For the convenience of comparison, the first scale 4121 is arranged on a side of the first marking surface 412 close to the second marking surface 121, and the second scale 1212 is arranged on a side of the second marking surface 121 close to the first marking surface 412, so that the first scale 4121 and the second scale 1212 can be connected when the translation matching portion 41 and the mounting member 12 move relative to each other.
[0045] This specification does not limit the specific connection method between the translational matching part 41 and the mounting part 12. For example, the translational matching part 41 and the mounting part 12 can be connected by sliding grooves or slide rails, or the translational matching part 41 and the mounting part 12 can also be connected by sliding sleeves. In this embodiment, a slide rail is provided on the mounting part 12. Specifically, a strip-shaped protrusion is formed at the end of the mounting part 12. A step surface is formed between the strip-shaped protrusion and the end surface of the mounting part 12. The protrusion and the step surface extend along the first direction X to form a slide rail on the mounting part 12. The translational matching part 41 is provided with a slide groove, which passes through the translational matching part 41 along the first direction X. The translational matching part 41 is slidably sleeved on the slide rail of the mounting part 12 through the slide groove.
[0046] In order to facilitate the fixing of the translational matching part 41 and the mounting part 12, in this embodiment, the robot load device 100 further includes a positioning member 50, which can be movably inserted into the translational matching part 41. The mounting part 12 is provided with a positioning hole 123, and the positioning member 50 can be movably limited in the positioning hole 123 to limit the relative position of the translational matching part 41 and the mounting part 12. The positioning member 50 is inserted into the translational matching part 41 and limited in the positioning hole 123, thereby improving the connection stability between the translational matching part 41 and the mounting part 12. This specification does not limit the specific type of the positioning member 50, and the positioning member 50 may include at least one of fasteners such as a pin, a screw, and a bolt.
[0047] In this embodiment, in order to adapt to the change in position between the translational matching portion 41 and the mounting member 12 during relative movement, please refer to Figure 4 , the number of the positioning holes 123 is set to be multiple, and the multiple positioning holes 123 are arranged along the first direction X. The translational matching part 41 is provided with a clearance groove 414, which passes through both sides of the translational matching part 41 and is connected with the positioning holes 123. The clearance groove 414 passes through the translational matching part 41 along the second direction Z and extends along the first direction X, wherein the second direction Z is perpendicular to the first direction X. The positioning member 50 is movably inserted into the clearance groove 414 and can move in the clearance groove 414 along the first direction X. As an example, the positioning member 50 includes a bolt, the bolt is inserted into the clearance groove 414, the bolt head is clamped outside the clearance groove 414, and the other end of the bolt extends into the positioning hole 123 and is threadedly connected with the positioning hole 123. When the relative position between the translational matching part 41 and the mounting member 12 changes, the positioning member 50 is moved in the clearance groove 414 along the first direction X, and inserted into other positioning holes 123 for fixing. In this embodiment, a plurality of positioning members 50 may be provided, so as to further improve the connection stability between the translational matching portion 41 and the mounting member 12 .
[0048] The mounting member 12 is generally in the shape of a rectangular plate, and a plurality of mounting through holes 125 are provided on the mounting member 12, and the mounting through holes 125 are arranged at intervals along the second direction Z. The rotating shaft 14 can be selectively disposed in one of the mounting through holes 125, and the second direction Z is perpendicular to the direction of the axis 14. The load plate 20 is mounted on the mounting member 12 via the rotating shaft 14, and the rotating shaft 14 can be mounted on any of the mounting through holes 125. The plurality of mounting through holes 125 are arranged at intervals along the second direction Z, and the center of mass position of the robot load device 100 can be greatly adjusted by adjusting the position of the rotating shaft 14.
[0049] This specification does not limit the specific direction of the axial direction of the rotating shaft 14. For example, the axial direction of the rotating shaft 14 can be parallel to the first direction X, or can intersect with the first direction X (for example, disposed). In this embodiment, the axial direction of the rotating shaft 14 is arranged along the third direction Y, and the third direction Y, the first direction X, and the second direction Z are perpendicular to each other. The rotating shaft 14 is penetrated by the mounting member 12, and both ends of the rotating shaft 14 protrude from the mounting member 12 to carry the load plate 20. The number of load plates 20 can be provided in plurality, and the plurality of load plates 20 can be detachably arranged on the rotating shaft 14. By increasing or decreasing the number of load plates 20, the weight of the robot load device 100 can be matched according to a certain adjustment step.
[0050] Please also see Figure 2 and Figure 5 In this embodiment, the load disk 20 is a disk, and the side wall surface of the load disk 20 is a cylindrical surface 21. The geometric center G of the load disk 20 is in the same straight line with the center of mass of the load disk 20, and the center of mass of the load disk 20 is located on the axis P2P of the cylindrical surface 21, and the axis P2 of the cylindrical surface 21 is parallel to the axis P1 of the rotating shaft 14. Among them, the center of mass is the abbreviation of the center of mass, which refers to an imaginary point on the material system where the mass is considered to be concentrated. The load disk 20 is a disk, and its center of mass is on the axis of the load disk 20. The end face of the complex USB flash drive 20 and the center of each section are located on the axis of the load disk 20, that is, on the axis P2 of the cylindrical surface 21.
[0051] The load plate 20 is provided with a mounting hole 23, through which the load plate 20 is sleeved on the rotating shaft 14. The hole axis of the mounting hole 23 is parallel to and spaced from the geometric center G, so that the load plate 20 is eccentrically mounted on the rotating shaft 14. When the rotating shaft 14 drives the load plate 20 to rotate relative to the mounting member 12, the center of mass position of the load plate 20 can be changed.
[0052] This specification does not limit the specific connection method between the locking member 30 and the rotating shaft 14. For example, in this embodiment, the rotating shaft 14 can be a screw, the locking member 30 is a nut, the rotating shaft 14 is inserted into the installation through hole 125, the load disc 20 is sleeved on the rotating shaft 14, the locking member 30 is threadedly connected to the rotating shaft 14, and is tightened to abut against the load disc 20 to fix the load disc 20 to the mounting member 12. In other embodiments, the locking member 30 can also be inserted into the load disc 20 and directly connected to the mounting member 12.
[0053] In order to facilitate the control of the rotation angle of the load disc 20 relative to the mounting member 12, in this embodiment, a third scale 127 is provided on the side wall of the mounting member 12, and the third scale 127 is arranged in a direction perpendicular to the axis P2 of the cylindrical surface 21.

The side wall surface of the load disc 20 is provided with a second indexing groove 25, and the second indexing groove 25 is arranged along the circumference of the load disc 20. The second indexing groove 25 and the third scale 127 are used to cooperate to represent the rotation angle of the load disc 20 relative to the mounting member 12. When the load disc 20 rotates to different positions relative to the mounting member 12, the second indexing groove 25 corresponding to the third scale 127 is different.
[0054] The second indexing groove 25 may include a plurality of grooves radially extending along the load disk 20. The present specification does not limit the specific arrangement of the second indexing groove 25. For example, the angle between two adjacent grooves of the second indexing groove 25 is 10°. The load disk 20 may also be provided with digital labels corresponding to the second indexing groove 25 for easy identification. For example, the digital labels on the load disk 20 may include 0, 10, 20, 30, 330, 340, 350, etc. Before use, the load disk 20 is in the initial position, and the second indexing groove 25 marked as 0 on the load disk 20 is aligned with the reference scale of the load end 203. Please refer to Figure 6 When adjusting the center of mass, the value to be adjusted is first calculated, and then the load plate 20 is rotated by a predetermined angle relative to the load end 203 , and then the load plate 20 is fixed to the mounting member 12 by the positioning member 50 .
[0055] In order to facilitate observation of the second indexing groove 25, in the present embodiment, the second indexing groove 25 is formed on the end surface of the load disk 20 close to the end away from the mounting member 12, and extends to the peripheral wall of the load disk 20, so that the operator can clearly distinguish the relative position between the second indexing groove 25 and the reference scale of the load end 203.
[0056] In summary, in the robot load device 100 provided in the embodiment of the present application, the number of load plates 20 is adjustable. When in use, the load plates 20 can be increased according to the test requirements of the robot 200 to make it close to the required load weight. The load plate 20 is eccentrically arranged. When the load plate 20 rotates relative to the mounting member 12, the position of its center of mass will change. When the rotating disk 43 rotates relative to the load end 203, the load plate 20 is driven to rotate together through the translation matching portion 41 to adjust the center of mass position. The mounting member 12 moves along the first direction X relative to the translation matching portion 41, which can change the center of mass position of the robot load device 100. The first scale 4121 and the second scale 1212 facilitate the operator to accurately adjust the center of mass position, thereby improving the convenience and applicability of the robot load device 100. The inertia and center of mass position of the robot load device 100 provided in the embodiment of the present application can be adjusted, which can quickly meet the load adjustment requirements, and is suitable for load testing of various robots 200, thereby improving the test efficiency and reducing the test cost.
