In the existing technology, when inspecting the motor stator, multiple probes are needed to inspect the top and inner wall of the stator separately. Especially when inspecting the inner wall of the stator, each probe needs to be equipped with two driving components. One driving component is used to drive the probe to move up and down to extend into the motor stator, and the other driving component is used to drive the probe to move towards the inner wall of the motor stator to make contact with the inner wall. For the overall device, there are many parts, the production cost is high, and the operation is inconvenient, which reduces the inspection efficiency. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Figures 1-8 The present invention relates to an automatic stator testing machine, comprising a machine base 10, a dividing turntable assembly 20, a human-machine interaction control device 30, a feeding assembly 40, and a testing assembly 60.

[0037] In this embodiment:

[0038] like Figure 4 As shown, the dividing turntable assembly 20 is mounted on the machine base 10. The dividing turntable assembly 20 includes a turntable 21, a divider 22, multiple positioning seats 23, and multiple clamping plates 24. The divider 22 is positioned below the turntable 21 and drives the turntable 21 to rotate for station switching. The multiple positioning seats 23 are arranged on the turntable 21 along its circumferential direction, and each clamping plate 24 is positioned on one side of a positioning seat 23. In this embodiment, the turntable 21 has four stations, and each station has two positioning seats 23 and two clamping plates 24.

[0039] like Figure 1-3As shown, the feeding component 40, negative pressure cleaning component 50, testing component 60, and unloading component 70 are arranged around the turntable 21 in the order of workstations, and all are connected to the human-machine interaction control device 30.

[0040] like Figure 5 As shown, the feeding assembly 40 includes a storage chain plate 41, a mounting frame 42, and a conveying module 43. The storage chain plate 41 is located on one side of the machine base 10, the mounting frame 42 is located above the storage chain plate 41, and the conveying module 43 is located on the mounting frame 42. The conveying module 43 is used to transport the stator 90 on the storage chain plate 41 to the corresponding workstation on the turntable 21.

[0041] The handling module 43 includes a lifting servo 431, a connecting plate 432, a feeding rotary drive 433, an inner support gripper 434, and a product sensor 435. The connecting plate 432 is slidably mounted on the mounting frame 42. The feeding rotary drive 433 is mounted on the connecting plate 432, and the inner support gripper 434 is mounted on the output end of the feeding rotary drive 433. The lifting servo 431 drives the connecting plate 432 to move up and down, thereby moving the feeding rotary drive 433 and the inner support gripper 434. The product sensor 435 is mounted on the connecting plate 432. When the product sensor 435 senses that the stator 90 is mounted on the positioning seat 23, it transmits a signal to the human-machine interface control device 30. The human-machine interface control device 30 controls the pressing plate 24 to move downward to press the stator 90.

[0042] like Figure 6 As shown, the negative pressure cleaning component 50 is disposed between the feeding component 40 and the testing component 60. The negative pressure cleaning component 50 includes a guide shaft seat 51, a mounting block 52, a slider 53, a pressing component 54, and a cylinder 55. The guide shaft seat 51 is vertically mounted on the machine base 10. The mounting block 52 is mounted on the guide shaft seat 51. The mounting block 52 is provided with a guide rail 521. The extension direction of the guide rail 521 is parallel to the axial direction of the guide shaft seat 51. The slider 53 is slidably mounted on the guide rail 521. The pressing component 54 is connected to the slider 53. The cylinder 55 drives the pressing component 54 and the slider 53 to move along the extension direction of the guide rail 521. The above configuration is used to clean dust and other impurities on the surface of the stator 90 to ensure the accuracy of subsequent testing.

[0043] like Figure 7 As shown, the test assembly 60 includes a mounting base 61, a guide post 62, a drive component 63, a mounting plate 64, and a probe assembly 65, which includes a probe 651 and a probe holder 652.

[0044] Mounting base 61 is mounted on machine base 10 and located on one side of turntable 21.

[0045] The drive component 63 is mounted on the mounting base 61 and is connected to the mounting plate 64 in a transmission manner.

[0046] The probe 651 and probe seat 652 are mounted on the mounting plate 64 and face downwards. The probe 651 is used to contact the top of the stator 90. The probe seat 652 has a spring piece 6521 on its side wall. The driving member 63 drives the mounting plate 64 to move so that the probe seat 652 extends into the stator 90 and the spring piece 6521 abuts against the inner wall of the stator 90 to achieve detection.

[0047] The guide post 62 is mounted on the mounting base 61, and the axial direction of the guide post 62 is parallel to the extension direction of the drive member 63.

[0048] In this embodiment, there are two probe assemblies 65. Each probe assembly 65 includes multiple probes 651 and a probe seat 652. The multiple probes 651 are arranged around the outer periphery of the probe seat 652. Each probe seat 652 is provided with two spring pieces 6521, which are arranged opposite to each other on both sides of the probe seat 652.

[0049] like Figure 8 As shown, the unloading assembly 70 includes a gripping assembly 71, a defective product flow channel 72, a good product flow channel 73, a carrier 74, a carrier positioning sensor 75, and a limiting member 76. The gripping assembly 71 includes a telescopic gripper 711 and an unloading sensor 712.

[0050] The defective product flow channel 72 and the good product flow channel 73 are horizontally arranged on one side of the turntable 21 in a straight line. After the material sensor 712 senses the incoming signal of the stator 90, the telescopic gripper 711 clamps the stator 90 and places it into the defective product flow channel 72 or the good product flow channel 73.

[0051] The carrier 74 is slidably mounted on the good product flow channel 73. The carrier position sensor 75 and the limiting member 76 are arranged opposite each other on both sides of the good product flow channel 73. When the carrier position sensor 75 senses the material coming into the carrier 74, it transmits the signal to the human-machine interface control device 30. The human-machine interface control device 30 controls the limiting member 76 to move so as to contact the carrier 74 for limiting.

[0052] The protective cover 80 is positioned above the machine base 10, and the human-machine interface control device 30 is located in the middle of the protective cover 80, on the operating side for feeding the stator 90. The height and position of the human-machine interface control device 30 are suitable for human-machine interaction operation.

[0053] The working principle of this application is as follows:

[0054] Under the control of the human-machine interface control device 30, the feeding assembly 40 transports the stator 90 to be tested to the feeding station on the turntable 21. The divider 22 drives the turntable 21 to rotate by one station angle, moving the already fed stator 90 to the station where the negative pressure cleaning assembly 50 is located. After cleaning, the divider 22 drives the turntable 21 to rotate by one station angle, moving the stator 90 to the station where the testing assembly 60 is located. The drive component 63 drives the mounting plate 64 to move so that the probe 651 contacts the top of the stator 90, the probe seat 652 extends into the stator 90, and the spring piece 6521 contacts the stator 90. The inner wall is contacted to achieve detection, and the detection result is transmitted to the human-machine interaction control device 30. After the detection is completed, the turntable 21 continues to rotate to rotate the stator 90 to the station where the unloading component 70 is located. The good products are unloaded into the good product flow channel 73 by the clamping component 71, and the defective products are sorted and unloaded into the defective product flow channel 72. When working at the next station, the previous station performs its work tasks at the same time, so that the work of each station can be processed in parallel. This effectively realizes the automated stator 90 loading, detection and unloading in a production line, which greatly improves production efficiency, reduces labor costs and improves product quality.

[0055] In this application, the probe assembly 65 includes different types of probes 651 and probe holders 652, which can detect different parts of the stator 90. At the same time, the structure is simple, with fewer parts for the overall device, lower production cost, and convenient operation, thus improving detection efficiency.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
