[0027] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0028] Example 1: Reference Figures 1-4, A roller runout and yaw automatic testing device, including a test bench 1. On the outer wall of the top of the test bench 1, there is a test seat 4 and a control display 7. On one side of the test bench 1, there is a six-axis robot 2, and a mechanical claw one 3 is arranged on the six-axis robot 2. Above the test seat 4, there is a lifting plate 5, and a driving mechanism is arranged on the lifting plate 5. On both outer walls of the bottom of the lifting plate 5, a pair of mounting plates one 16 are fixedly connected, and a roller one 17 is rotatably connected between each pair of mounting plates one 16. One end of one of the roller one 17 is provided with a rotating mechanism. On the middle outer wall of the bottom of the lifting plate 5, a pair of mounting plates two 22 are fixedly connected, and two rotating shafts 15 are rotatably connected between the mounting plates two 22. On the outer walls of the two rotating shafts 15, a gear three 14 is fixedly connected, and the two gear three 14 are meshed with each other. One end of one of the rotating shafts 15 is provided with a driving motor three 23. On the outer walls of the two rotating shafts 15, a telescopic mechanism is arranged, and a U-shaped frame 24 is arranged on each telescopic mechanism. A roller two 25 is rotatably connected to the inner wall of the U-shaped frame 24. A same rolling belt 13 is sleeved on the outer walls of the roller one 17 and the roller two 25. The six-axis robot 2 can automatically pick up the roller to be tested through the mechanical claw one 3, and then place the roller in the test seat 4 on the test bench 1, replacing the error of manual placement. Then the driving mechanism operates. First, the lifting plate 5 is moved directly above the test seat 4, and then the lifting plate 5 moves downward, so that the rolling belt 13 contacts the roller on the test seat 4 until the rolling belt 13 can wrap the upper part of the roller. Then the rotating mechanism operates, so that the rolling belt 13 drives the roller to roll. At the same time, the control display 7 controls the telescopic mechanism, so that the two telescopic mechanisms extend and retract irregularly. When the roller rolls, it simulates pressing it irregularly with different forces in different directions, which is more in line with the actual use and greatly improves the accuracy of the test. The test seat 4 can collect the data of the roller and send it to the control display 7, and the control display 7 analyzes the data to distinguish whether the roller is a good product or a defective product; and the driving motor three 23 can make the rotating shaft 15 connected to it rotate. Because the gear three 14 on the two rotating shafts 15 are meshed, the distance between the two roller two 25 is changed to adjust the rolling belt 13 to make it suitable for rollers of different sizes.

[0029] As a further scheme in the present invention, the driving mechanism includes a rotating column 9. The rotating column 9 is rotatably connected to the outer wall of the top of the test bench 1, and a gear one 10 is fixedly connected to the outer wall of the rotating column 9. On the outer wall of the top of the test bench 1, there is a driving motor one 12, and a gear two 11 is fixedly connected to the output shaft end of the driving motor one 12. The gear one 10 is meshed with the gear two 11. The driving motor one 12 drives the gear two 11 to rotate. Because the gear two 11 is meshed with the gear one 10 on the outer wall of the rotating column 9, the rotating column 9 can be rotated.

[0030] As a further solution in the present invention, a fixing plate 8 is fixedly connected to the top end of the rotating column 9, and an electric push rod 6 is installed on the fixing plate 8. The lifting plate 5 is fixedly connected to the telescopic end of the electric push rod 6. The height of the lifting plate 5 can be adjusted by the electric push rod 6.

[0031] As a further solution in the present invention, the rotating mechanism includes a second transmission wheel 21. A second driving motor 19 is arranged above the second transmission wheel 21. The output shaft end of the second driving motor 19 is fixedly connected with a first transmission wheel 18. A transmission belt 20 is sleeved on the first transmission wheel 18 and the second transmission wheel 21. The second driving motor 19 can make the first roller 17 rotate through the first transmission wheel 18, the transmission belt 20 and the second transmission wheel 21, so that the rolling belt 13 sleeved on the first roller 17 and the second roller 25 moves.

[0032] As a further solution in the present invention, the telescopic mechanism includes a hollow cylinder 26. A telescopic rod 30 is slidably connected to the top end of the hollow cylinder 26. A magnetic plate 29 is fixedly connected to the bottom end of the telescopic rod 30. An electromagnet 27 is arranged on the inner wall of the bottom of the hollow cylinder 26. A connecting spring 28 is fixedly connected between the electromagnet 27 and the magnetic plate 29. The magnetic force generated after the electromagnet 27 is energized is mutually exclusive with the magnetic plate 29. The top end of the telescopic rod 30 is fixedly connected with the rotating shaft 15. The U-shaped frame 24 is fixedly connected to the bottom end of the hollow cylinder 26. The control display 7 keeps the current input into the electromagnet 27 unchanged, so that the distance between the electromagnet 27 and the magnetic plate 29 remains unchanged. When it is necessary to press the roller, the control display 7 irregularly changes the magnitude of the current input into the electromagnet 27. When the current input into the electromagnet 27 becomes smaller, the magnetic force generated by the electromagnet 27 becomes smaller, so that the telescopic rod 30 retracts into the hollow cylinder 26. When the current input into the electromagnet 27 becomes larger, the length of the telescopic rod 30 extending out of the hollow cylinder 26 becomes longer.

[0033] Working principle: The six-axis robot 2 can automatically pick up the rollers to be tested through the mechanical claw 3, and then place the rollers into the test seats 4 on the test bench 1, replacing the error of manual placement. Then, the driving motor 12 drives the gear 11 to rotate. Since the gear 11 meshes with the gear 10 on the outer wall of the rotating column 9, the rotating column 9 can be rotated, and the lifting plate 5 can be moved directly above the test seat 4. Then, the electric push rod 6 makes the lifting plate 5 move downward, so that the rolling belt 13 contacts the roller on the test seat 4 until the rolling belt 13 can wrap the upper part of the roller. Then, the driving motor 19 can make the roller 17 rotate through the transmission wheel 18, the transmission belt 20 and the transmission wheel 21, so that the rolling belt 13 sleeved on the roller 17 and the roller 25 moves, so that the rolling belt 13 drives the roller to roll. When it is necessary to press the roller, the control display 7 is used to irregularly change the magnitude of the current input into the electromagnet 27. When the current input into the electromagnet 27 becomes smaller, the magnetic force generated by the electromagnet 27 becomes smaller, so that the telescopic rod 30 retracts into the hollow cylinder 26. When the current input into the electromagnet 27 becomes larger, the length of the telescopic rod 30 extending out of the hollow cylinder 26 becomes longer. Through the above operations, the two telescopic mechanisms can be telescoped irregularly, so that when the roller rolls, it simulates pressing it with different forces in different directions irregularly, which is more in line with the actual use and greatly improves the accuracy of the test. The test seat 4 can collect the data of the roller and send it to the control display 7, and the control display 7 analyzes the data to distinguish whether the roller is a good product or a defective product; and the driving motor 23 can make the connected rotating shaft 15 rotate. Since the gears 14 on the two rotating shafts 15 mesh, the distance between the two rollers 25 is changed to adjust the rolling belt 13 so that it is suitable for rollers of different sizes.

[0034] Embodiment 2: Refer to Figures 1-6 , a kind of automatic test equipment for roller runout and yaw. Compared with Embodiment 1, on the basis of Embodiment 1, a conveyor belt 31 is arranged on one side of the six-axis robot 2, and a plurality of U-shaped placement blocks 32 are arranged at equal intervals on the conveyor belt 31. Card slots 38 are arranged on both sides of the top of each U-shaped placement block 32.

[0035] As a further solution in the present invention, a placement table 36 is provided on the other side of the six-axis robot 2, and an XY-axis moving platform 34 is provided on the top of the placement table 36. A second mechanical claw 37 is installed on the XY-axis moving platform 34. A pair of placement plates 35 are provided on both sides of the top of the placement table 36, and a plurality of placement trays 33 are placed on each pair of placement plates 35. After the control display 7 differentiates the rollers into good or bad products, then control the six-axis robot 2 to pick up the rollers after the test through the first mechanical claw 3. When the roller is a good product, place it in the placement tray 33 on one of the pairs of placement plates 35. If the roller is a bad product, place it in the placement tray 33 on the other pair of placement plates 35, which is convenient for separating the good products from the bad products for unified management. When the placement tray 33 is full of rollers, the XY-axis moving platform 34 moves the full placement tray 33 to a place close to the staff through the second mechanical claw 37, which is convenient for the staff to pick up.

[0036] Working principle: After the control display 7 differentiates the rollers into good or bad products, then control the six-axis robot 2 to pick up the rollers after the test through the first mechanical claw 3. When the roller is a good product, place it in the placement tray 33 on one of the pairs of placement plates 35. If the roller is a bad product, place it in the placement tray 33 on the other pair of placement plates 35, which is convenient for separating the good products from the bad products for unified management. When the placement tray 33 is full of rollers, the XY-axis moving platform 34 moves the full placement tray 33 to a place close to the staff through the second mechanical claw 37, which is convenient for the staff to pick up.

[0037] Example 3: Refer to Figures 1-7 , a kind of automatic test equipment for roller runout and yaw. Compared with Example 2, on the basis of Example 2, two second electric push rods 39 are provided on the outer wall of one side of the placement table 36, and the telescopic ends of the two second electric push rods 39 are fixedly connected to the same mounting frame 40. A threaded rod 41 is rotatably connected to the inner wall of the mounting frame 40, and a fourth driving motor 45 is provided at one end of the threaded rod 41.

[0038] As a further solution in the present invention, a threaded slider 43 is threadedly slidably connected to the threaded rod 41, and a third electric push rod 44 is fixedly connected to the outer wall of the threaded slider 43. The telescopic end of the third electric push rod 44 is fixedly connected to a third mechanical claw 42. The second electric push rod 39 moves the third mechanical claw 42 on the mounting frame 40 above the full placement tray 33, and then the fourth driving motor 45 rotates the threaded rod 41. Thus, through the cooperation of the threaded slider 43, the third electric push rod 44 and the third mechanical claw 42, the full placement tray 33 can be grabbed, and the good products and bad products can be automatically separated and stacked, solving the problems of product accumulation and misplacement, reducing the floor area, and reducing the errors caused by humans.

[0039] Working principle: The electric push rod II 39 moves the mechanical claw III 42 on the mounting bracket 40 above the fully loaded tray 33. Then, the drive motor IV 45 rotates the threaded rod 41, so that through the cooperation of the threaded slider 43, the electric push rod III 44 and the mechanical claw III 42, the fully loaded tray 33 can be grasped, and the qualified products and unqualified products can be automatically separated and stacked, solving the problems of product accumulation and misplacement, reducing the floor area, and reducing the errors caused by humans.
