Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] Reference Figures 1 to 3The present application provides a stator testing device, including a workbench 10, a first conveyor belt 20 disposed on the workbench 10, a testing station 30, a marking station 40, a barcode scanning station 50 disposed sequentially along the first conveyor belt 20, and a pickup device 60. The testing station 30 is detachably provided with a clamp 70 for clamping the stator 1. The clamp 70 includes a clamping plate 71 located at the top, a plurality of cylinders (not shown in the figure) evenly disposed along the clamping plate 71, a sleeve assembly 72 disposed at the bottom of the clamping plate 71, and a plurality of grippers 73 controlled by each cylinder and located outside the sleeve assembly 72.

[0031] In this application, the testing station 30, the marking station 40, and the barcode scanning station 50 are integrated on the first conveyor belt 20 on the workbench 10. Through the transportation of the first conveyor belt 20, automatic testing, marking, and barcode scanning are realized. In this fully automatic working mode, the work efficiency is greatly improved. Moreover, the stator 1 is clamped by the fixture 70 during testing, which facilitates the testing of the stator 1. The fixture 70 is detachable and can be adapted to clamp different stators 1.

[0032] Reference Figure 2 , Figure 3 In this embodiment, the sleeve assembly 72 includes a first sleeve 74 disposed at the bottom of the clamping plate 71 and a second sleeve 75 disposed at the bottom of the first sleeve 74. The outer diameter of the second sleeve 75 is smaller than the outer diameter of the first sleeve 74. The first sleeve 74 has a plurality of hinge shafts 741 evenly arranged circumferentially. Each gripper 73 is bent, and each gripper 73 is hinged to each hinge shaft 741 with the bend 731 as the hinge point. The two ends of the gripper 73 are an outer end 732 and an inner end 733, respectively, with the bend 731 closer to the outer end, and the inner end 733 formed by bending downwards from the bend 731. The output end of each cylinder extends below the clamping plate 71 and connects to the outer end 732 of each gripper 73, while the inner end 733 of each gripper 73 faces the outer wall of the second sleeve 75. Thus, when the output end of the cylinder moves up and down, the outer surfaces of each gripper 73 move up and down, pushing each gripper 73 to rotate around the hinge point. This causes the inner ends 733 of the grippers 73 to either approach or move away from the outer wall of the second sleeve 75. During clamping, the stator 1 is fitted onto the second sleeve 75, and the cylinder drives each gripper 73 to rotate, causing the inner ends of the grippers 73 to approach the second sleeve 75 and clamp the top wall of the stator 1 onto the second sleeve 75.

[0033] Furthermore, in this embodiment, the second sleeve 75 is provided with a plurality of first notches (not labeled in the figure) along its circumference, and each first notch is provided with a flexible pad 76, and each flexible pad 76 is directly opposite to each gripper 73. That is, each gripper 73 clamps the top wall of the stator 1 on the flexible pad 76, thus providing flexible clamping and avoiding damage to the stator 1.

[0034] Furthermore, in this embodiment, the first sleeve 74 is provided with a plurality of second notches 742 along its circumference. The hinge shaft 741 is horizontally positioned at the second notches 742. The bend 731 of the gripper 73 passes through the hinge shaft 741, and two limiting pads 743 are also fitted on the hinge shaft 741, with the two limiting pads 743 located on both sides of the bend 731. The two limiting pads 743, located on both sides of the bend 731 of the gripper 73, serve to limit its movement. Moreover, this hinge structure is simple, easy to install, and has good stability.

[0035] Specifically, the output end of the cylinder is provided with a connecting block 77, and the bottom of the connecting block 77 is provided with an inverted U-shaped third notch 771. The outer end of the gripper 73 extends into the third notch 771, and the bottom of the outer end of the gripper 73 is also provided with a limiting post 78. The two ends of the limiting post 78 are respectively connected to the third notch 771. In this way, the outer end 732 of the gripper 73 is fixed in the connecting third notch 771 by the limiting post 78, realizing the connection between the outer end 732 and the connecting block 77. When the output end of the cylinder moves up and down, it drives the connecting block 77 to drive the outer end 732 of the gripper 73 to move.

[0036] Reference Figure 2 , Figure 3 Furthermore, this embodiment also includes a lifting device 80 located below the first conveyor belt 20 and at the test station 30 for lifting the stator 1 off the first conveyor belt 20. Specifically, when the stator 1 moves on the first conveyor belt 20, it is moved by a carrier 13 placed on the first conveyor belt 20, the carrier 13 being hollow in the middle. When the carrier 13 moves to the test station 30, the lifting device 80 passes upward through the carrier 13 to lift the stator 1, so that the top of the stator 1 can be fitted onto the second sleeve 75. Then, the action of the cylinder controls the grippers 73 to clamp the stator 1 onto the second sleeve 75, thereby facilitating testing. After the test is completed, the grippers 73 release the stator 1, the lifting device 80 moves downward, the stator 1 returns to the carrier 13, and continues to move forward on the first conveyor belt 20.

[0037] Reference Figure 1 In this embodiment, there are two test stations 30, which are sequentially arranged on the first conveyor belt 20. The two test stations 30 can test the two stators 1 simultaneously. Of course, under certain requirements, the two test stations 30 can also perform different tests on the stators 1. The testing at the test stations 30 can be adjusted according to the actual situation.

[0038] In this embodiment, the tested stator 1 moves forward to the marking station 40, where a barcode or other marking is printed on the stator 1. The marking may contain relevant parameter information or test information of the stator 1. After passing through the marking station 40, the stator 1 passes through the barcode scanning station 50, where the barcode is scanned for data entry and collection.

[0039] In this embodiment, the stator 1, after being scanned, moves forward to below the pickup device 60, where it is picked up by the pickup device 60 and placed in a different area. The workbench 10 has a defective material area 11, and the pickup device 60 can pick up the defective stator 1 and place it in the defective material area 11. Simultaneously, the workbench 10 is also equipped with a second conveyor belt 12, from which... Figure 1 As can be seen from the diagram, the second conveyor belt 12 is parallel to the first conveyor belt 20, and the picking device 60 can pick up the qualified stator 1 onto the second conveyor belt 12 and transport it to the next work station.

[0040] In this embodiment, the picking device 60 includes a support 61 mounted on the worktable 10, a horizontal moving device 62 mounted on the support 61, a vertical moving device 63 mounted on the horizontal moving device 62, and a robotic arm 64 mounted on the vertical moving device 63. That is, the picking device 60 can move horizontally and vertically, thus facilitating the picking of defective or qualified stators 1 to their corresponding positions.

[0041] In this embodiment, the above-mentioned testing device is used to automatically complete the detection, marking, barcode scanning, and sorting of stator 1, which greatly improves efficiency.

[0042] 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.
