Description

Technical Field

[0001] The present invention belongs to the technical field of robot performance testing, and specifically refers to a performance testing device for intelligent manufacturing of industrial robots. Background Art

[0002] As an important part of intelligent manufacturing, industrial robots are mechanical equipment with the ability to learn and perform tasks autonomously. They can replace humans to complete repetitive, high-risk and tedious tasks. Industrial robots usually use advanced sensors and control systems, which can sense the surrounding environment and respond accordingly, thereby achieving efficient automated production.

[0003] The existing performance testing devices have the following problems:

[0004] The existing performance testing equipment for industrial robot intelligent manufacturing does not have the function of testing the positioning performance of the power sliding system of the robot arm under no-load movement and load movement, and is also unable to detect the deviation in the positioning accuracy of the power system caused by the potential energy generated when the robot arm transports objects from a high place to a low place. Therefore, it cannot meet the existing demand for the use of performance testing equipment for industrial robot intelligent manufacturing. Summary of the invention

[0006] The technical solution adopted in this scheme is as follows: This scheme proposes a performance testing equipment for industrial robot intelligent manufacturing, including a robot sliding seat, a guide slide rail, a driving rack, a potential energy height difference type load mechanism and a safety limit mechanism. The guide slide rails are symmetrically arranged on the upper walls at both ends of the robot sliding seat, and the driving racks are symmetrically arranged on the upper wall and bottom wall of the robot sliding seat in a group of two. The potential energy height difference type load mechanism is arranged on the guide slide rail, and the safety limit mechanism is arranged on the upper walls at both ends of the robot sliding seat. The potential energy height difference type load mechanism includes a driving mechanism, a differential potential mechanism, a weight increasing mechanism, a positioning mechanism and a distance measuring mechanism. The driving mechanism is arranged on the upper wall of the robot sliding seat, the differential potential mechanism is arranged on the upper wall of the driving mechanism, the weight increasing mechanism is arranged on the differential potential mechanism, the positioning mechanism is arranged at one end of the differential potential mechanism away from the driving mechanism, and the distance measuring mechanism is arranged on the side wall of the robot sliding seat.

[0007] As a further preferred embodiment of the present invention, the driving mechanism includes a load platform, a motor seat, a driving motor, a reducer, a driving gear set, a proximity switch and a sensing block. The load platform is slidably arranged on the upper wall of the guide rail, the motor seat is symmetrically arranged on the bottom walls at both ends of the load platform, the driving motor is arranged inside the motor seat, the reducer is arranged on the side of the motor seat away from the load platform, the power end of the driving motor passes through the motor seat and is connected to the power input end of the reducer, the driving gear set is arranged at the power output end of the reducer, the driving gear set is meshed with the driving rack, the proximity switch is passed through the upper walls at both ends of the guide rail, and the sensing blocks are symmetrically arranged on the bottom walls at both ends of the load platform in groups of two; the differential mechanism includes differential columns, differential slides and extension springs, the differential columns are symmetrically arranged on the upper wall of the load platform, the differential slides are slidably arranged between the differential columns, and the extension spring is arranged on the differential slide outside the differential columns. The weight-increasing mechanism comprises a gravity ball cylinder, an iron plug and a cast iron weight, wherein the gravity ball cylinder is arranged on the inner wall of the potential difference slide plate, the iron plug is arranged through the upper wall and the bottom wall of the gravity ball cylinder, the iron plug is threadedly connected to the gravity ball cylinder, and the cast iron weight is arranged inside the gravity ball cylinder; the positioning mechanism comprises a positioning plate and a positioning electromagnet, wherein the positioning plate is arranged at the end of the potential difference column away from the load platform, and the positioning electromagnet is arranged on the bottom wall of the positioning plate; the distance measuring mechanism comprises a distance measuring sensor, a distance measuring groove and a distance measuring plate, wherein the distance measuring sensor is symmetrically arranged on both sides of the robot sliding seat, the distance measuring groove is arranged on the upper wall of the robot sliding seat between the driving racks, the distance measuring groove is through-arranged, the distance measuring plates are symmetrically arranged on both sides of the load platform, the end of the distance measuring plate away from the load platform is located inside the distance measuring groove, the distance measuring plate is slidably arranged on the inner wall of the distance measuring groove, and the distance measuring end of the distance measuring sensor is arranged through inside the distance measuring groove.

[0008] When in use, in the initial state, the extension spring is set to an extension setting. The extension of the extension spring drives the differential slide plate to slide and descend along the differential column. The differential column drives the gravity ball cylinder to be located on the upper wall of the load platform. The driving motor drives the reducer to rotate through the power end, and the reducer drives the driving gear set to rotate. The driving gear set is meshed with the driving rack. The driving gear set drives the load platform to slide along the guide rail. After the load platform drives the sensing block to reach the position of the proximity switch, the proximity switch senses the sensing block, so that the power end of the driving motor stops driving the reducer to rotate, and the reducer reduces the output speed of the driving motor. At this time, the sensing block and the proximity switch are arranged opposite to each other, and the distance measuring sensor measures the distance measuring plate on the side of the load platform close to it through the distance measuring end, and records the distance between the distance measuring sensor and the distance measuring plate, which is the positioning distance of the reducer when the driving motor stops under no-load;

[0009] When testing the safety performance of the power system of the robot sliding base, rotate the iron plug, the iron plug is screwed out from the upper wall of the gravity ball cylinder, add the cast iron weights required by the user into the gravity ball cylinder, and then screw the iron plug into the upper wall of the gravity ball cylinder. At this time, the gravity ball cylinder is located on the upper wall of the load platform, and the drive motor drives the load platform to one end of the guide slide rail through the power end. The distance measuring plates arranged on both sides of the load platform are respectively at the farthest and closest distances to the distance measuring sensor. The induction blocks and proximity switches at the closest distance between the distance measuring plate and the distance measuring sensor are arranged relative to each other, driving the load platform to move to the farthest side between the distance measuring sensor and the distance measuring plate, so as to facilitate the test of the load platform at Positioning accuracy under load, the power end of the driving motor rotates, and the speed of the power end of the driving motor is adjusted to the speed required by the user. The driving motor drives the reducer to rotate through the power end, and the reducer drives the driving gear set to roll along the driving rack. The driving gear set drives the load platform to slide along the guide rail at a certain speed. When the sensing block on the farthest side of the distance measuring plate and the distance measuring sensor in the initial state reaches the position of the proximity switch, the power end of the driving motor stops rotating, and then the distance between the distance measuring sensor and the distance measuring plate is compared with the distance of the load platform under no-load, so as to obtain the positioning accuracy deviation of the load platform under load and no-load;

[0010] The driving motor drives the load platform to move, and the load platform drives the distance measuring sensor at the current position to move the induction block on the side of the distance measuring board that is closest to the distance measuring board. The distance measuring sensor and the induction block on the side of the distance measuring board that is closest to the distance measuring board move to a position set opposite to the proximity switch. Then the positioning electromagnet is fixed to the bottom wall of the positioning plate and energized to generate magnetism. The positioning plate attracts the iron plug through magnetic force. With the help of magnetic attraction, the differential slide plate is manually lifted. The differential slide plate drives the gravity ball cylinder to slide along the differential column to increase the height. The iron plug and the positioning electromagnet fit each other. The positioning electromagnet attracts the iron plug through magnetic force. The differential slide plate is fixed at the end of the differential column away from the load platform. The driving motor drives the driving gear set to roll along the driving rack through the power end. The moving gear set drives the load platform to slide along the guide rail. When the load platform slides and drives the sensing block to move toward the proximity switch at the other end of the guide rail, the current passed into the positioning electromagnet gradually decreases, the positioning electromagnet's adsorption magnetic force on the iron plug weakens, and the differential slide plate continues to descend under the action of the gravity of the gravity ball barrel and the restoring elastic force of the extension spring. When the load platform drives the sensing block to reach the position of the proximity switch, the drive motor stops rotating, and the gravity ball barrel falls to the upper wall of the load platform and is placed. At this time, the distance between the gravity ball barrel and the distance measuring board is measured by the distance measuring sensor, so that the inertial influence value of the gravity potential energy generated by the gravity ball barrel when it falls from a high place after being converted into kinetic energy can be obtained.

[0011] Preferably, the safety limit mechanism includes a limit block, a threaded hole and a limit bolt. The limit blocks are symmetrically arranged on the upper walls of both ends of the robot sliding seat in a group of two. The limit block is coaxially and horizontally arranged with the guide rail. The threaded hole is arranged on the side wall of the limit block, and the limit bolt is arranged inside the threaded hole. The limit bolt is threadedly connected to the threaded hole.

[0012] When in use, the distance that the limit bolt extends to one end of the guide rail is set according to the minimum value measured between the distance measuring sensor and the distance measuring plate. The limit bolt is adjusted by rotating along the threaded hole to extend to one side of the guide rail. The distance between the limit bolt and the load platform can be adjusted according to the inertial movement force generated by the load platform when loaded, so as to avoid the load platform colliding with the limit bolt during normal operation, and the limit bolt can be adjusted to a safe limit position accordingly.

[0013] Specifically, a controller is provided on an upper wall at one end of the robot sliding seat.

[0014] Wherein, the controller is electrically connected to the driving motor, the proximity switch, the positioning electromagnet and the distance measuring sensor respectively.

[0015] Preferably, the model of the controller is HAD-SC200.

[0016] Furthermore, the model of the distance measuring sensor is C1-JCS1501.

[0017] The beneficial effects achieved by adopting the above structure are as follows:

[0018] Compared with the prior art, this solution adopts a method of comparing the no-load positioning accuracy with the load inertia deviation and the potential energy inertia deviation, which can test the positioning deviation generated by the load platform when it is loaded, and can adjust the limit distance of the limit bolt according to the load deviation value, so that the limit bolt can avoid the collision between the limit bolt and the load platform while ensuring the safe limit distance. Secondly, through the simulation of the robot arm carrying goods from a high place to a low place, the positioning accuracy deviation of the power system set on the robot sliding seat used by the robot arm after being affected by the potential energy can be tested, so that the power system set on the robot sliding seat used by the robot arm can be better adjusted, and then the mechanical The transfer accuracy of the arm. When the load platform slides and drives the sensing block to move toward the proximity switch at the other end of the guide rail, the current passed into the positioning electromagnet gradually decreases, and the adsorption magnetic force of the positioning electromagnet on the iron plug weakens. The differential slide plate continues to descend under the action of the gravity of the gravity ball barrel and the restoring elastic force of the extension spring. When the load platform drives the sensing block to reach the position of the proximity switch, the drive motor stops rotating, and the gravity ball barrel falls to the upper wall of the load platform and is placed. At this time, the distance between the gravity ball barrel and the distance measuring board is measured by the distance measuring sensor, so that it can be obtained that when the gravity ball barrel falls from a high place, the gravitational potential energy generated by it is converted into kinetic energy, which indirectly affects the inertial influence value of the positioning accuracy of the load platform after the movement stops.

[0039] A controller 32 is disposed on an upper wall at one end of the robot sliding base 1 .

[0040] The controller 32 is electrically connected to the driving motor 8 , the proximity switch 11 , the positioning electromagnet 23 and the distance measuring sensor 25 , respectively.

[0041] The model of the controller 32 is HAD-SC200.

[0042] The model of the distance measuring sensor 25 is C1-JCS1501.

[0043] When used specifically, in the first embodiment, in the initial state, the extension spring 16 is extended, and the extension spring 16 extends to drive the differential slide plate 15 to slide down along the differential column 14, and the differential column 14 drives the gravity ball cylinder 18 to be located on the upper wall of the load platform 6;

[0044] Specifically, the controller 32 controls the drive motor 8 to start, the drive motor 8 drives the reducer 9 to rotate through the power end, the reducer 9 drives the drive gear set 10 to rotate, the drive gear set 10 is meshed with the drive rack 3, the drive gear set 10 drives the load platform 6 to slide along the guide rail 2, the load platform 6 drives the sensor block 12 to reach the position of the proximity switch 11 at one end of the guide rail 2, and the positioning accuracy of the load platform 6 under no-load is tested, the controller 32 controls the drive motor 8 to start again to drive the load platform 6 to slide along the guide rail 2, the load platform 6 drives the sensor block 12 on the bottom wall of the other end to reach the contact set at the other end of the guide rail 2 At the position of the proximity switch 11, the controller 32 controls the proximity switch 11 to start, and the proximity switch 11 senses the induction block 12, so that the power end of the drive motor 8 stops driving the reducer 9 to rotate, and the reducer 9 reduces the output speed of the drive motor 8. At this time, the induction block 12 is arranged opposite to the proximity switch 11, and the controller 32 controls the distance sensor 25 to start. The distance sensor 25 measures the distance plate 27 close to one side of the load platform 6 through the distance measuring end, and records the distance between the distance sensor 25 and the distance plate 27, which is the positioning position of the load platform 6 on the guide rail 2 driven by the reducer 9 when the drive motor 8 under no-load stops;

[0045] When the safety performance of the power system of the robot sliding base is load tested, the iron plug 19 is manually rotated, and the iron plug 19 is screwed out from the upper wall of the gravity ball tube 18, and the cast iron weight 20 required by the user is added to the inside of the gravity ball tube 18, and then the iron plug 19 is screwed into the upper wall of the gravity ball tube 18. At this time, the gravity ball tube 18 is located on the upper wall of the load platform 6, and the controller 32 controls the drive motor 8 to start. The drive motor 8 drives the load platform 6 to one end of the guide slide rail 2 through the power end. The distance measuring plates 27 arranged on both sides of the load platform 6 are respectively at the farthest and closest distances from the distance measuring sensor 25. The sensing block 12 and the proximity switch 11 at the closest distance between the distance measuring plate 27 and the distance measuring sensor 25 are arranged relative to each other, and the load platform 6 is driven to move to the farthest side between the distance measuring sensor 25 and the distance measuring plate 27, so as to facilitate the testing of the load platform 6. To determine the positioning accuracy under load, the power end of the driving motor 8 rotates, and the speed of the power end of the driving motor 8 is adjusted to the speed required by the user. The driving motor 8 drives the reducer 9 to rotate through the power end, and the reducer 9 drives the driving gear set 10 to roll along the driving rack 3. The driving gear set 10 drives the load platform 6 to slide along the guide rail 2 at a certain speed. When the sensing block 12 on the farthest side of the ranging plate 27 and the ranging sensor 25 in the initial state reaches the position of the proximity switch 11, the controller 32 controls the power end of the driving motor 8 to stop rotating, and then compares the distance between the ranging sensor 25 under load and the ranging plate 27 with the distance between the ranging sensor 25 and the ranging plate 27 when the load platform 6 is unloaded, thereby testing the positioning accuracy deviation of the load platform 6 when loaded and when unloaded;

[0046] The influence of the potential energy generated by the test load platform 6 on its positioning accuracy is tested. The controller 32 controls the driving motor 8 to drive the load platform 6 to move. The load platform 6 drives the sensing block 12 on the side of the closest distance between the distance sensor 25 and the distance measuring plate 27 at the current position to move. The sensing block 12 on the side of the closest distance between the distance sensor 25 and the distance measuring plate 27 moves to a position opposite to the proximity switch 11. Then the controller 32 controls the positioning electromagnet 23 to start. The positioning electromagnet 23 is fixed on the bottom wall of the positioning plate 22 and energized to generate magnetism. The positioning plate 22 attracts the iron plug 19 through magnetic force. With the help of magnetic attraction, the differential potential slide plate 15 is manually lifted. The differential potential slide plate 15 drives the gravity ball cylinder 18 to slide and rise along the differential potential column 14. The iron plug 19 fits against the positioning electromagnet 23. The positioning electromagnet 23 attracts the iron plug 19 through magnetic force. The differential potential slide plate 15 is fixed at the end of the differential potential column 14 away from the load platform 6. The driving motor 8 drives the driving gear set 10 to roll along the driving rack 3 through the power end, and the driving gear set 10 drives the load platform 6 to slide along the guide rail 2. When the load platform 6 slides and drives the sensing block 12 to move toward the proximity switch 11 at the other end of the guide rail 2, the controller 32 controls the current passed into the positioning electromagnet 23 to gradually decrease, and the adsorption magnetic force of the positioning electromagnet 23 on the iron plug 19 is weakened. The differential slide plate 15 continuously decreases in height under the action of the gravity of the gravity ball barrel 18 and the restoring elastic force of the extension spring 16. When the load platform 6 drives the sensing block 12 to reach the position of the proximity switch 11, the driving motor 8 stops rotating, and the gravity ball barrel 18 falls to the upper wall of the load platform 6 and is placed. At this time, the distance between the gravity ball barrel 18 and the distance measuring plate 27 is measured by the distance measuring sensor 25, so that the inertial influence value of the gravity potential energy generated by the gravity ball barrel 18 when it falls from a high place after being converted into kinetic energy on the positioning accuracy of the load platform 6 can be obtained;

[0047] According to the measured minimum value between the distance measuring sensor 25 and the distance measuring plate 27, the distance that the limit bolt 31 extends to one end of the guide slide rail 2 is set, and the limit bolt 31 is manually rotated. The limit bolt 31 is rotated along the threaded hole 30 to adjust the distance extended to one side of the guide slide rail 2. The distance between the limit bolt 31 and the load platform 6 can be adjusted according to the inertial movement force generated by the load platform 6 when loaded, thereby avoiding the load platform 6 from colliding with the limit bolt 31 during normal operation, and then the limit bolt 31 can be adjusted to a safe limit position accordingly; the above operation can be repeated the next time it is used.
