[0002] The robot's repeatability refers to the robot's ability to repeatedly position its hand (end effector) at the same target position, that is, whether the robot can accurately return to the predetermined position during positioning and moving operations to achieve stable and reliable execution of tasks. The robot's repeatability directly determines whether the robot can maintain a stable operating state during long-term operation. At present, laser trackers are usually used to detect the robot's repeatability.

[0029] Embodiment 1:

[0030] The utility model provides a robot repeated positioning accuracy detection device.

[0031] In one embodiment of the utility model, a robot repeatable positioning accuracy detection device includes a mounting frame 1, a telescopic column 2, a transmission assembly, an adjustment assembly and a detection assembly. The mounting frame 1 is used to be detachably connected to an external fixed structure. A transmission assembly is provided at the top of the telescopic column 2, and the transmission assembly is located in the mounting frame 1. The transmission assembly includes a rotating shaft, a rack 3 vertically arranged on the telescopic column 2, and a gear 4 meshing with the rack 3. The gear 4 is penetrated at one end of the rotating shaft, and the rotating shaft is penetrated on the mounting frame 1. The end of the rotating shaft away from the gear 4 is detachably connected to the adjustment assembly.

[0032] The adjustment component includes a mounting seat 5, a slide rail 6 arranged on the mounting seat 5, and two sliders 7 that are in sliding contact with the slide rail 6. The two sliders 7 can move closer to or farther away from each other and are respectively rotatably installed with extension rods 8. The detection component is communicatively connected to the external control module and is used to measure the precise displacement of the robot end effector during repeated positioning. The detection component includes a first measuring meter 9 that is movably arranged on the mounting seat 5 with a limit position, and two second measuring meters 10 that are respectively movably installed on the extension rods 8 with a limit position.

[0033] The utility model provides a robot repetitive positioning accuracy detection device. When in use, the utility model is set at a preset position to perform repetitive positioning accuracy detection on the robot. Specifically, Figures 1 to 5 As shown, by detachably connecting the mounting frame 1 to the external fixed structure at the preset position, the detachable connection method can be a threaded connection, which is convenient for assembly and disassembly and can ensure the stability of the connection between the mounting frame 1 and the external fixed structure; when the utility model is not in use or needs to be transported, since a transmission assembly is provided at the top of the telescopic column 2, the rack 3 in the transmission assembly is vertically arranged at the top of the telescopic column 2, so that the rack 3 can be driven by the telescopic column 2 to move up and down synchronously, at this time, the gear 4 meshing with the rack 3 rotates, and the adjusting assembly is driven to rotate synchronously through the rotating shaft passing through the gear 4, and the adjusting assembly is provided with a detection assembly that is communicatively connected to the external control module and is used to measure the precise displacement of the robot end effector during repeated positioning, so that the utility model can rotate and store the detection assembly when it is not in use, thereby not only reducing the occupied space of the utility model, facilitating transportation and handling, but also storing and protecting the detection assembly, reducing the probability of the detection assembly being bumped and damaged during transportation.

[0034] Furthermore, since a slide rail 6 and two sliders 7 that are respectively in sliding contact with the slide rail 6 are provided on the mounting seat 5 in the adjustment assembly, and the two sliders 7 can be moved closer to or farther away from each other, the driving mode for the two sliders 7 to slide relative to the slide rail 6 can be respectively driven by a hydraulic cylinder or a mechanism that can drive the two sliders 7 to make linear reciprocating movements. The two sliders 7 are rotatably mounted with extension rods 8, and the two extension rods 8 are respectively mounted with second measuring gauges 10 in a limited and movable manner, so that the two second measuring gauges 10 can be moved closer to or farther from each other under the drive of the two sliders 7, so as to adapt to and detect robot end effectors of different lengths, and are flexible to use; at the same time, the two second measuring gauges 10 and the two extension rods 8 can be limited and movable in a threaded connection, and specific reference can be made to the thread locking method of the vernier in the vernier caliper, that is, by respectively sleeved the two second measuring gauges 10 on the two extension rods 8, the two second measuring gauges 10 can be respectively moved relative to the two extension rods 8, so as to adapt to and detect robot end effectors of different widths, thereby improving applicability and expanding the detection range; when the two second measuring gauges 10 are respectively moved and adjusted into place, the two second measuring gauges 10 can be respectively firmly pressed against the two extension rods 8 by tightening the screws, thereby realizing the limiting of the two second measuring gauges 10, and the two second measuring gauges 10 can be quickly disassembled and assembled by only screwing the screws, which is convenient for inspection and maintenance. In addition, the limiting movement of the first measuring meter 9 and the mounting seat 5 in the detection assembly can be achieved by threaded connection or snap-on connection, thereby facilitating quick disassembly and assembly of the first measuring meter 9 and facilitating inspection and maintenance.

[0035] It can be understood that when the present invention is actually used, by setting scales on the extension rod 8, the relative positions of the two second measuring scales 10 can be easily adjusted to ensure the consistency of the moving distances of the two second measuring scales 10 on the two extension rods 8; at the same time, when the present invention is not in use or needs to be carried, since the two extension rods 8 are respectively rotatably mounted on the two sliders 7, the two second measuring scales 10 can be stored by relatively rotating the two extension rods 8, thereby further reducing the space occupied by the present invention and the probability of the two second measuring scales 10 being bumped and damaged, and the use is reliable.

[0036] It should be noted that the first measuring gauge 9 and the two second measuring gauges 10 can be electronic micrometers in the prior art, and the first measuring gauge 9 and the two second measuring gauges 10 are both connected to the external control module in communication, and the communication connection method can be wireless transmission technology in the prior art. At the same time, the measurement principle of detecting the robot end effector by the electronic micrometer is also a mature prior art, which will not be described in detail here. The utility model is only aimed at solving the problem that the existing robot repeatable positioning accuracy detection device cannot perform adaptability detection on robot end effectors of different sizes, which reduces the applicability, and at the same time cannot store the detection unit, so that the overall space occupied is large and it is not convenient for transportation and handling.

[0037] In one embodiment, a connecting ear 11 is provided on one side of the first measuring meter 9 opposite to the instrument panel, and positioning notches 12 are provided on opposite sides of the connecting ear 11. A limit seat 13 is detachably installed on one side of the mounting seat 5. The limit seat 13 is located between the two sliders 7, and a groove 14 is provided on the limit seat 13 for the connecting ear 11 to extend into. Protrusions 15 are formed on the groove walls on opposite sides of the groove 14 at positions corresponding to the positioning notches 12. It can be understood that, if Figures 1 to 5 As shown, when the first measuring meter 9 needs to be installed, the staff can directly insert the connecting ear 11 on the first measuring meter 9 into the groove 14, so that the protrusion 15 on the side wall of the groove 14 is snapped into the positioning notch 12 on the connecting ear 11, thereby realizing the quick installation of the first measuring meter 9, which is simple and convenient to use; similarly, the staff can also pull the first measuring meter 9 upward and disengage the protrusion 15 from the positioning notch 12, thereby realizing the quick disassembly of the first measuring meter 9, which is convenient for inspection and maintenance.

[0038] In one embodiment, the adjustment component also includes two connecting seats 16, on which two second measuring scales 10 are detachably mounted, and the two connecting seats 16 are respectively slidably mounted on two extension rods 8, and one end of the two extension rods 8 is rotatably mounted with a hinge seat 17, and any hinge seat 17 is detachably connected to the corresponding slider 7, and a limit block 18 is detachably mounted on one end of any extension rod 8 away from the hinge seat 17, and an anti-slip pattern is formed on the outer wall of the limit block 18.

[0039] Specifically, Figures 1 to 3As shown, since two second measuring meters 10 are detachably mounted on the two connecting seats 16, the two second measuring meters 10 can be detachably connected to the two connecting seats 16 by threaded connection, so as to facilitate the disassembly and assembly of the two second measuring meters 10. Furthermore, since the two limiting seats 13 are respectively installed on the two extension rods 8 in a limited sliding manner, the limited sliding manner can also be threaded connection, that is, by setting screws on the connecting seats 16, and tightening or loosening the connecting seats 16 and the extension rods 8 by screwing the screws, the movement adjustment and fixed limit of the second measuring meter 10 relative to the extension rod 8 are realized, which is convenient to use. It can be understood that since one end of the two extension rods 8 is rotatably mounted with an articulated seat 17, and any articulated seat 17 is detachably connected to the corresponding slider 7, it is convenient to disassemble and replace the two extension rods 8, which is conducive to the maintenance of the second measuring meter 10, and the overall assembly is more convenient, and the structural design is simple and reasonable. In addition, by detachably installing a limit block 18 at one end of the two extension rods 8 away from the hinge seat 17, the second measuring meter 10 can be effectively prevented from falling off the extension rod 8 when moving and adjusting, and the limit block 18 can be detachably installed by a threaded connection, and the anti-slip grooves on the outer wall of the limit block 18 make it easy for the staff to screw and disassemble the limit block 18.

[0040] In one embodiment, any hinge seat 17 includes two ribs 19, the extension rod 8 is rotatably mounted between the two ribs 19 through a locking member, and a stopper 20 for abutting against the extension rod 8 is formed on one side between the two ribs 19 away from the limiting seat 13. Specifically, Figures 1 to 3 As shown, the baffle plate allows the extension rod 8 to rotate only within a range of 0 to 90 degrees relative to the slider 7, thereby preventing the two second measuring meters 10 from rotating at too large an angle to affect detection, and the use is reliable.

[0041] In one embodiment, the extension direction of the slide rail 6 is consistent with the extension direction of the mounting seat 5. The slide rail 6 is provided with a through slot 21, and an adjusting screw is inserted into the through slot 21. The adjusting screw is formed with two threaded sections with opposite rotation directions, and both ends of the adjusting screw extend out of the slide rail 6 and are detachably connected to a hand wheel 22. The two sliders 7 are respectively threadedly engaged with the two threaded sections through the through slot 21. It can be understood that, if Figures 1 to 3 As shown, when it is necessary to adjust the distance between the two second measuring gauges 10, the staff can rotate the hand wheel 22 to make the adjusting screw rotate synchronously. Since the two sliders 7 are respectively engaged with the two threaded sections through the through grooves 21, the two sliders 7 can move closer to or farther away from each other relative to the slide rail 6 under the action of the adjusting screw, so as to adapt to robot end effectors of different lengths. The structural design is simple and reasonable.

[0042] In one embodiment, specifically, Figures 1 to 4As shown, the transmission assembly also includes a vertical plate 23, a guide rail 24 and a guide block 25. The vertical plate 23 is vertically arranged at the top of the telescopic column 2. The guide rail 24 and the rack 3 are detachably installed on the opposite sides of the vertical plate 23, and the extension direction of the guide rail 24 is consistent with the extension direction of the vertical plate 23. The guide block 25 is arranged on the mounting frame 1 and is used for sliding contact with the guide rail 24. The sliding contact between the guide block 25 and the guide rail 24 can guide the rack 3 to ensure the stability of the rack 3 when it moves up and down.

[0043] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
