[0008] Furthermore, a lifting mechanism is provided below the conveyor belt. The lifting mechanism is used to lift the motor carrier on the conveyor belt and detach it from the conveyor belt so that the first picking device can pick up the motor and put it into the drawer-type clamping device.

[0009] Furthermore, the second picking device includes a four-axis robot and a second picking head disposed at the output end of the four-axis robot.

[0010] Furthermore, the second pickup head includes a second rotating shaft rotatably connected to the output end of the four-axis robot, an inverted U-shaped bracket connected to the second rotating shaft, and two second grippers disposed on the inverted U-shaped bracket.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

Therefore, they should not be construed as limitations on this application.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] Reference Figures 1 to 4 The present application provides a motor testing device, including a workbench 10, a conveyor belt 20 disposed on the workbench 10, a closed noise testing chamber 30 disposed on one side of the conveyor belt 20, a first pickup device 40 for conveying the motor between the conveyor belt 20 and the closed noise testing chamber 30, a performance testing device 50 disposed on one side of the conveyor belt 20, and a second pickup device 60 for conveying the motor between the conveyor belt 20 and the performance testing device 50. The closed noise testing chamber 30 has a drawer-type clamping device 31 that can be automatically opened and closed for installing the motor.

[0034] In this application, a closed noise test chamber 30 and a performance test device 50 are sequentially arranged on one side of the conveyor belt 20, which can sequentially perform noise and performance tests on the motor. The two tests are independent of each other and are performed automatically in sequence, which improves the testing efficiency. Moreover, after the first pickup device 40 picks up the motor from the conveyor belt 20 to the drawer-type clamping device 31, the drawer-type clamping device 31 automatically closes, and the motor is tested for noise in the closed noise test chamber 30, which can obtain more accurate noise detection results.

[0035] There are two enclosed noise test chambers 30, each equipped with a drawer-type clamping device 31, arranged side by side. When the first pickup device 40 places a motor from the conveyor belt 20 into one of the drawer-type clamping devices 31, the drawer-type clamping device 31 closes, and the enclosed noise test chamber 30 tests it. At the same time, the motor in the other enclosed noise test chamber 30 has finished testing, the drawer-type clamping device 31 opens, and the first pickup device 40 transfers the tested motor back onto the conveyor belt 20. In this way, the two enclosed noise test chambers 30 operate simultaneously, avoiding a waiting state for the first pickup device 40 and achieving higher collaborative efficiency.

[0036] In this embodiment, the testing software inside the enclosed noise testing chamber 30 includes calibration software for vibration and noise sensors. The sensors are calibrated periodically and irregularly, and the calibration results are managed. The calibration software has autonomous deep learning capabilities, which can continuously extract features from abnormal audio signals of motors for deep model training, and achieve more accurate noise analysis by continuously iterating and optimizing model parameters. Furthermore, due to its enclosed nature, it is immune to interference from the external environment (such as trailers, the roar of external machines, human speech, etc.).

[0037] Furthermore, in this embodiment, the first picking device 40 includes a six-axis robot 41 and a first picking head 42 disposed at the output end of the six-axis robot. The six-axis robot 41 is used for motor transfer, achieving flexible posture adjustment in three-dimensional space through six rotating axes, with high repeatability and positioning accuracy. Most importantly, the six-axis robot 41 has a large arm span radius, allowing it to transfer motors between the conveyor belt 20 and the two drawer-type clamping devices 31 of the two enclosed noise test chambers 30.

[0038] Specifically, refer to Figure 2 The first pickup head 42 includes a first rotating shaft 421 rotatably connected to the output end of the six-axis robot 41, a first connecting plate 422 perpendicularly connected to the first rotating shaft 421, and two first grippers 423 symmetrically disposed at both ends of the first connecting plate 422. Specifically, the first grippers 423 are pneumatic two-finger parallel grippers, which can effectively grip cylindrical shaft parts such as motors. In this embodiment, the first grippers 423 are respectively disposed at both ends of the first connecting plate 422, that is, the first pickup head 42 has two sets of first grippers 423. The two sets of first grippers 423 always protect one set holding a motor and the other set in an empty state. When one of the first grippers 423 picks up a motor on the conveyor belt 20, the output end of the six-axis robot 41 moves to the open drawer-type clamping device 31. The output end of the six-axis robot 41 drives the first rotating shaft 421 to rotate 180°. At this time, the first gripper 423 with no material on the first pick-up head 42 picks up the motor that has been tested on the drawer-type clamping device 31. The output end of the six-axis robot 41 drives the first rotating shaft 421 to rotate 180° again. The other first gripper 423 with material on the first pick-up head 42 places the untested motor picked up from the conveyor belt 20 onto the empty drawer-type clamping device 31. After the drawer-type clamping device 31 detects the presence of material, it automatically closes to perform testing. Meanwhile, the six-axis robot 41 moves to place the tested motor onto the conveyor belt 20 and continues to convey it forward.

[0039] By using this alternating loading and unloading method, the loading and unloading cycle can be controlled within 10 seconds, greatly improving work efficiency.

[0040] Furthermore, in this embodiment, since all six axes of the six-axis robot 41 are rotating axes and the output end cannot move up or down in the vertical direction, a lifting mechanism is provided below the conveyor belt 20 to facilitate the six-axis robot 41 in picking up the motor. When the motor carrier of the motor reaches the designated position to be picked up, that is, above the lifting mechanism, the lifting mechanism lifts upward to lift the motor carrier on the conveyor belt 20 and remove it from the conveyor belt 20 so that the six-axis robot 41 can pick up the motor into the drawer-type clamping device 31.

[0041] Specifically, in this embodiment, the second picking device 60 includes a four-axis robot 61 and a second picking head 62 disposed at the output end of the four-axis robot 61. Compared to the six-axis robot 41, the four-axis robot 61 has two fewer rotation axes, making it less flexible. However, the four-axis robot 61 can adapt to high-speed picking and placing operations. Its four key axes are the X-axis, Y-axis, Z-axis, and the rotation axis at the output end. The X-axis and Y-axis are for rotation, while the Z-axis allows for vertical movement. The four-axis robot 61 also significantly improves work efficiency by transferring motors between the conveyor belt 20 and the performance testing device 50.

[0042] Specifically, refer to Figure 3 The second pickup head 62 includes a second rotating shaft 621 rotatably connected to the output end of the four-axis robot 61, an inverted U-shaped bracket 622 connected to the second rotating shaft 621, and two second grippers 623 disposed on the inverted U-shaped bracket 622. Similarly, the second pickup head 62 can be horizontally flipped to alternately pick up motors, improving work efficiency. Specifically, when one of the second grippers 623 picks up a motor on the conveyor belt 20, the output end of the four-axis robot 61 moves to the performance testing device 50. The output end of the four-axis robot 61 drives the second rotating shaft 621 to rotate 180°. At this time, the second gripper 623 with no material on the second pick-up head 62 picks up the motor that has been tested on the performance testing device 50. The output end of the four-axis robot 61 drives the second rotating shaft 621 to rotate 180° again. The other second gripper 623 with material on the second pick-up head 62 places the untested motor picked up from the conveyor belt 20 onto the empty performance testing device 50. After the performance testing device 50 detects the presence of material, it performs clamping and testing. Meanwhile, the four-axis robot 61 moves to place the tested motor onto the conveyor belt 20 and continues to convey it forward.

[0043] Furthermore, in this embodiment, a support 11 is provided on the workbench 10, and two four-axis robots 61 (only one is shown in the figure) are provided on the support 11. The two four-axis robots 61 are mounted on a base 12, and the two performance testing devices 50 are located on both sides of the support 11. In this way, the two four-axis robots 61 simultaneously transmit motors to the two performance testing devices 50, which can also match the testing rhythm of the two enclosed noise testing chambers 30 mentioned above, avoiding standby mode and greatly improving work efficiency.

[0044] Reference Figure 4 In this embodiment, the performance testing device 50 includes a performance testing head 51, a first fixed pin 52 disposed below the performance testing head 51, and a second fixed pin 53 disposed opposite to the first fixed pin 52 and capable of moving closer to or away from the first fixed pin 52. The second fixed pin 53 is disposed on a horizontal moving device 54, and is moved by the horizontal moving device to move closer to or away from the first fixed pin 52 in order to clamp or release the motor.

[0045] In this embodiment, the workbench 10 is also provided with a non-conforming product placement area 13. After being tested by the performance testing device 50, the qualified products are picked up by the second picking device 60 and moved forward on the conveyor belt 20 to the next process or a designated position, while the non-conforming products are picked up to the non-conforming product placement area 13, thus realizing product sorting.

[0046] In this embodiment, a barcode scanning device 80 for scanning and binding motors is also provided on the conveyor belt 20. Using the barcode scanning device 80 to scan and bind the motors facilitates the collection and storage of motor information.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
