[0019] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

A pair of mounting plates 22 are fixedly connected to the wall, and two rotating shafts 15 are rotatably connected between the mounting plates 22. The outer walls of the two rotating shafts 15 are fixedly connected with gears 3 14, and the two gears 3 14 are meshed with each other. A driving motor 3 23 is arranged at one end of one of the rotating shafts 15. The outer walls of the two rotating shafts 15 are provided with telescopic mechanisms, and U-shaped frames 24 are arranged on the telescopic mechanisms. The inner wall of the U-shaped frame 24 is rotatably connected with rollers 25. The outer walls of the rollers 17 and 25 are sleeved with the same rolling belt 13. The six-axis robot 2 can automatically pick up the The roller to be tested is then placed in the test seat 4 on the test bench 1, replacing the error of manual placement. The driving mechanism is then operated, first moving the lifting plate 5 to the top of the test seat 4, then moving the lifting plate 5 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, and then the rotating mechanism is operated, so that the rolling belt 13 rolls with the roller. At the same time, the control display 7 controls the telescopic mechanism, so that the two telescopic mechanisms are irregularly extended and retracted. When the roller rolls, the simulation passes By pressing it irregularly in different directions with different forces, it is more suitable for 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. The control display 7 analyzes the data to distinguish whether the roller is a good product or a bad product; and the driving motor three 23 can rotate the rotating shaft 15 connected thereto. Because the gears three 14 on the two rotating shafts 15 are engaged, the distance between the two rotating rollers 25 is changed, and the rolling belt 13 is adjusted to make it suitable for rollers of different sizes.

[0021] As a further scheme of the present invention, the driving mechanism includes a rotating column 9, which is rotatably connected to the outer wall of the top of the test bench 1, and the outer wall of the rotating column 9 is fixedly connected to a gear 10, a driving motor 12 is arranged on the outer wall of the top of the test bench 1, and the output shaft end of the driving motor 12 is fixedly connected to a gear 2 11, the gear 10 is meshed with the gear 2 11, and the driving motor 12 drives the gear 2 11 to rotate, and because the gear 2 11 is meshed with the gear 10 on the outer wall of the rotating column 9, the rotating column 9 can be rotated.

[0022] As a further solution in the present invention, a fixed plate 8 is fixedly connected to the top of the rotating column 9, and an electric push rod 6 is installed on the fixed plate 8. The lifting plate 5 is fixedly connected to the telescopic end of the electric push rod 6, and the height of the lifting plate 5 can be adjusted by the electric push rod 6.

[0023] As a further solution in the present invention, the rotating mechanism includes a transmission wheel 21, a drive motor 21 is arranged above the transmission wheel 21, and the output shaft end of the drive motor 21 is fixedly connected to the transmission wheel 18, and a transmission belt 20 is provided on the transmission wheel 18 and the transmission wheel 21. The drive motor 2 19 can rotate the roller 17 through the transmission wheel 18, the transmission belt 20 and the transmission wheel 21, thereby moving the rolling belt 13 mounted on the roller 17 and the roller 25.

[0024] As a further solution in the present invention, the telescopic mechanism includes a hollow cylinder 26, the top of the hollow cylinder 26 is slidably connected to a telescopic rod 30, and the bottom of the telescopic rod 30 is fixedly connected to a magnetic plate 29, an electromagnet 27 is arranged on the inner wall of the bottom of the hollow cylinder 26, and a connecting spring 28 is fixedly connected between the electromagnet 27 and the magnetic plate 29, the magnetic force generated by the electromagnet 27 after power is turned on repel the magnetic plate 29, the top of the telescopic rod 30 is fixedly connected to the rotating shaft 15, the U-shaped frame 24 is fixedly connected to the bottom 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, and when the roller needs to be pressed, the control display 7 irregularly changes 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, and 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.

[0025] Working principle: The six-axis robot 2 can automatically pick up the roller to be tested through the mechanical claw 3, and then place the roller in the test seat 4 on the test bench 1, replacing the error of manual placement, and then drive the motor 12 to drive the gear 2 11 to rotate. Because the gear 2 11 is meshed 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 to the top of the test seat 4. Then the electric push rod 16 allows the lifting plate 5 to 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 2 19 can rotate the roller 17 through the transmission wheel 18, the transmission belt 20 and the transmission wheel 2 21, so that the rolling belt 13 mounted on the roller 17 and the roller 2 25 moves, so that the rolling belt 13 rolls with the roller. When the roller needs to be pressed, the control display 7 irregularly changes the input to 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 is retracted into the hollow tube 26. When the current input into the electromagnet 27 becomes larger, the length of the telescopic rod 30 extending out of the hollow tube 26 becomes longer. Through the above operation, the two telescopic mechanisms can be irregularly extended and retracted, so that when the roller rolls, it is simulated that different forces are used in different directions to press it irregularly, which is more in line with 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. The control display 7 analyzes the data and distinguishes whether the roller is a good product or a defective product; and the driving motor three 23 can rotate the rotating shaft 15 connected thereto. Because the gears three 14 on the two rotating shafts 15 are engaged, the distance between the two rollers two 25 is changed, and the rolling belt 13 is adjusted to make it suitable for rollers of different sizes.

[0026] Example 2: Reference Figure 1-Figure 6 , a roller bounce and runout automatic testing equipment, compared with Example 1, on the basis of Example 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 distances on the conveyor belt 31, and each U-shaped placement block 32 is provided with a clamping groove 38 on both sides of the top.

[0027] 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, and a mechanical claw 2 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 wobble plates 33 are placed on each pair of placement plates 35. After the control display 7 distinguishes whether the roller is a good product or a defective product, the six-axis robot 2 is controlled to pick up the roller after the test through the mechanical claw 1 3. When the roller is a good product, it is placed in the wobble plate 33 on one pair of placement plates 35. If the roller is a defective product, it is placed in the wobble plate 33 of the other pair of placement plates 35, so as to separate the good products from the defective products and manage them in a unified manner. If the wobble plate 33 is full of rollers, the XY-axis moving platform 34 moves the full wobble plate 33 to a place close to the staff through the mechanical claw 2 37, so as to facilitate the staff to pick it up.

[0028] Working principle: After the control display 7 distinguishes whether the roller is good or bad, it then controls the six-axis robot 2 to pick up the roller after the test through the mechanical claw 1 3. When the roller is good, it is placed in the wedge plate 33 on one pair of placement plates 35. If the roller is bad, it is placed in the wedge plate 33 of the other pair of placement plates 35, so as to separate the good and bad products and manage them in a unified manner. If the wedge plate 33 is full of rollers, the XY-axis moving platform 34 moves the full wedge plate 33 to a place close to the staff through the mechanical claw 2 37, so that the staff can pick it up easily.

[0030] As a further solution in the present invention, a threaded slider 43 is threadedly connected to the threaded rod 41, and an electric push rod 3 44 is fixedly connected to the outer wall of the threaded slider 43, and a mechanical claw 3 42 is fixedly connected to the telescopic end of the electric push rod 3 44. The electric push rod 39 moves the mechanical claw 3 42 on the mounting frame 40 to the top of the full wobble plate 33, and then drives the motor 45 to rotate the threaded rod 41, so that the full wobble plate 33 can be grabbed through the cooperation of the threaded slider 43, the electric push rod 3 44 and the mechanical claw 3 42, and the good products and the bad products can be automatically stacked separately, which solves the problem of product accumulation and misplacement, reduces the floor space occupied, and reduces the errors caused by human beings.
