[0025] Embodiment 1

[0026] This embodiment provides a stator testing device, which includes: a testing box body 100, a conveying assembly 200, and a testing assembly 300. A detection cavity 101 is formed on the testing box body 100. The conveying assembly 200 extends into the detection cavity 101. The testing assembly 300 includes a clamping member 301 and a telescopic detection head. The clamping member 301 is arranged inside the detection cavity 101 and is used to abut and fix the stator to be measured. The telescopic detection head is arranged on one side of the detection cavity 101 and is used to connect the stator to be measured.

[0027] Please refer to Figure 1As shown in the figure, in this embodiment, a detection cavity 101 is provided at the lower end of the test box body 100. Both ends of the detection cavity 101 are open, facilitating the conveying assembly 200 to extend into the detection cavity 101. The conveying assembly 200 passes through the detection cavity 101 of the test box body 100, and the conveying assembly 200 can be connected to the production or assembly line of the stator. The assembled stator moves under the action of the conveying assembly 200 and passes through the detection cavity 101 of the test box body 100. At this time, the test assembly 300 in the detection cavity 101 automatically detects the stator at the lower end. Specifically, a clamping member 301 and a telescopic detection head are provided in the detection cavity 101. When the stator to be measured moves into the detection cavity 101, the clamping member 301 abuts against the stator to be measured, thereby assisting in fixing the stator to be measured. At the same time, the telescopic detection head extends out and is connected to the terminal of the stator to be measured, and the stator to be measured is powered on through the telescopic detection head. By collecting relevant current and voltage values, it can be detected whether the stator is qualified. After a single stator is detected, the conveying assembly 200 operates to convey the next stator to be measured into the detection cavity 101, and at the same time convey the already detected stator to the next production station. The entire detection process can be carried out continuously, without manual operation or assisted monitoring by a small number of staff, saving labor costs and improving production efficiency.

[0028] Optionally, in some embodiments of this embodiment, the clamping member 301 includes a first telescopic cylinder 3011 and a ground wire connector 3012. The ground wire connector 3012 is arranged at the telescopic end of the first telescopic cylinder 3011, and the ground wire connector 3012 is used to connect the stator to be measured to ground the stator to be measured.

[0029] Please refer to Figure 2 As shown in the figure, in this embodiment, the first telescopic cylinder 3011 is connected to the test box body 100. The telescopic end of the first telescopic cylinder 3011 can abut against the stator to be measured, thereby playing a role in fixing the stator to be measured. The telescopic end of the first telescopic cylinder 3011 is provided with a ground wire connector 3012. After the telescopic end of the first telescopic cylinder 3011 abuts against the stator to be measured, the ground wire connector 3012 is connected to the stator to be measured to ground the stator to be measured. In this embodiment, the ground wire connector 3012 can be connected to a ground wire to eliminate the static electricity of the stator to be measured, avoid interference with the telescopic detection head, and ensure the accuracy of the telescopic detection head during detection.

[0030] Optionally, in some embodiments of this embodiment, a sliding tube 3013 is arranged on the first telescopic cylinder 3011. The ground wire connector 3012 is slidably arranged in the sliding tube 3013, and a return spring is arranged in the sliding tube 3013 to make the ground wire connector 3012 abut against the stator to be measured.

[0031] Please refer to Figure 2As shown, in this embodiment, a sliding tube 3013 is provided at the telescopic end of the first telescopic cylinder 3011, and the ground wire connector 3012 is disposed inside the sliding tube 3013. The sliding tube 3013 is used to connect the ground wire connector 3012 to ensure the stability of the ground wire connector 3012. At the same time, it protects the abutting connector to prevent damage to the ground wire connector 3012 and improve the service life of the ground wire connector 3012. The ground wire connector 3012 can slide along the length direction of the sliding tube 3013. At the same time, a return spring is disposed inside the sliding tube 3013, and the return spring provides an elastic force to keep the ground wire connector 3012 in its initial position all the time. After the ground wire connector 3012 abuts against the stator to be measured, the ground wire connector 3012 moves and compresses the return spring, and the return spring provides an elastic force to keep the ground wire connector 3012 in abutment with the stator to be measured all the time, ensuring the connection stability between the ground wire connector 3012 and the stator to be measured. At the same time, the return spring also plays a buffering role to prevent a large pressure from directly acting on the surface of the stator to be measured, resulting in damage to the stator to be measured and improving the safety during testing.

[0032] Optionally, in some embodiments of this embodiment, the telescopic detection head includes a second telescopic cylinder 3021 and a plurality of test pins 3022. The second telescopic cylinder 3021 is connected to the test box 100, and the test pins 3022 are disposed at the telescopic end of the second telescopic cylinder 3021. The test pins 3022 are used to connect the wire interfaces of the stator to be measured.

[0033] Please refer to Figure 3 As shown, in this embodiment, the second telescopic cylinder 3021 is connected to the test box 100, and the second telescopic cylinder 3021 is located on one side of the conveying assembly 200. After the stator to be measured is conveyed into the detection cavity 101, the second telescopic cylinder 3021 extends, driving the test pins 3022 to move and connect with the wire connectors of the stator to be measured, thereby connecting the circuit of the stator to be measured, and thus performing a detection operation on the stator to be measured. In this embodiment, the number of test pins 3022 can be three. It should be noted that the existing stator usually has three-phase circuits of U, V, and W. Therefore, three test pins 3022 are provided to connect to the three wiring ports of the stator to be measured respectively, which is convenient for detecting the circuit of the stator to be measured and judging whether the stator to be measured is qualified.

[0034] Optionally, in some embodiments of this embodiment, the test pin 3022 is slidably connected to the second telescopic cylinder 3021, and an elastic member is disposed at the sliding connection between the test pin 3022 and the second telescopic cylinder 3021, and the elastic member drives the test pin 3022 to reset.

[0035] Please refer to Figure 3As shown, in this embodiment, the test thimble 3022 is slidably connected to the telescopic end of the second telescopic cylinder 3021. The elastic member can adopt structures such as springs or elastic sheets. The elastic member provides elastic force to keep the test thimble 3022 always connected to the stator to be measured, ensuring the stability of the circuit connection during detection and improving the accuracy of the measurement results.

[0036] Optionally, in some embodiments of this embodiment, the stator testing device further includes a central processor 400, and the central processor 400 is electrically connected to the testing component 300.

[0037] Please refer to Figure 1 As shown, in this embodiment, the central processing can adopt an existing programmable control circuit board, on which a control circuit and related detection circuits are integrated. The specific circuit structure is not the inventive point of this application and can be designed according to actual needs or existing detection circuits can be adopted as long as the detection effect can be achieved, and this embodiment is not limited. The central processor 400 is electrically connected to the testing component 300, and is used to supply power to the testing component 300 and the stator to be measured and detect relevant data of the stator to be measured, and judge whether the stator to be measured is qualified.

[0038] Optionally, in some embodiments of this embodiment, a control panel 500 is provided on the test box 100, and the control panel 500 is electrically connected to the central processor 400.

[0039] Please refer to Figure 1 As shown, in this embodiment, the control panel 500 is provided with operation buttons and an emergency stop button. The control panel 500 is electrically connected to the central processor 400, and the operator can adjust the entire device by operating the control panel 500.

[0040] Optionally, in some embodiments of this embodiment, the stator testing device further includes an alarm device 600, and the alarm device 600 is signal-connected to the central processor 400.

[0041] Please refer to Figure 1 As shown, in this embodiment, the alarm device 600 is a lighting indicator, and the lighting indicator is signal-connected to the central processor 400 in a wired or wireless manner. When the central processor 400 detects that the stator to be measured is unqualified through the testing component 300, an indication signal is sent through the lighting indicator, which is convenient for the operator to adjust in time or mark the stator to be measured correspondingly, facilitating subsequent processing.

[0042] Optionally, in some other embodiments, the alarm device 600 can also adopt a sound indicator to prompt the operator by sending a sound alarm signal.

[0043] Optionally, in some embodiments of this embodiment, a blocker is provided inside the detection cavity 101, and the blocker is used to fix the stator to be measured.

[0044] In this embodiment, the stopper adopts a commercially available laser sensor or linear velocity sensor of any model, which is used to detect whether there is a stator to be detected on the conveying component 200. Whether there is a stator to be measured on the conveying component 200 is judged by detecting the position of the object on the conveying component 200, and whether the stator to be measured moves to the detection position is detected through the movement track of the stator to be measured. When the stator to be measured moves into the detection chamber 101, the conveying component 200 stops moving, ensuring that the customized stator to be measured can be accurately docked with the test component 300 after stopping.

[0045] When the stator testing device provided in this embodiment is in use, first, the stator to be measured is moved to the detection chamber 101 through the conveying component 200, and the position of the stator to be measured is detected by the stopper. When the stator to be measured moves to the accurate position, the conveying component 200 stops moving, and the stator to be measured enters the test preparation. At this time, first, the central processor 400 or the operator judges whether the equipment is working properly and whether an alarm signal is issued. If the equipment is working properly, the test component 300 is controlled to test the stator to be measured. If the central processor 400 detects that the stator to be measured meets the requirements, the conveying component 200 is started to convey the next stator to be measured for detection. If the central processor 400 detects that the stator to be measured does not meet the requirements, an alarm signal is issued through the alarm device 600 and the detection is paused, waiting for the operator to handle. The operator checks to judge whether there is poor contact between the test component 300 and the stator to be measured and conducts a secondary detection. If the secondary detection is still unqualified, the stator is marked, then the stator testing device is reset, and the above steps are repeated for the detection operation.

[0046] In summary, the embodiment of the present utility model provides a stator testing device, which includes: a test box body 100, a conveying component 200, and a test component 300. A detection chamber 101 is opened on the test box body 100, the conveying component 200 extends into the detection chamber 101, the test component 300 includes a clamping member 301 and a telescopic detection head, the clamping member 301 is arranged inside the detection chamber 101 and is used to abut and fix the stator to be measured, and the telescopic detection head is arranged on one side of the detection chamber 101 and is used to connect the stator to be measured. The stator testing device provided in this application automatically conveys the stator to be measured through the conveying component 200, and fixes and detects the stator through the clamping member 301 and the telescopic detection head, achieving the effect of automatic testing and fast detection speed.
