It includes a main body mechanism, a control mechanism, a storage mechanism, a scanning mechanism, and a receiving mechanism. The control mechanism is located at the front end of the main body mechanism, and the storage mechanism is located inside the main body mechanism. This utility model allows the control mechanism to reflect detection data in real time, facilitating timely observation and understanding of the composite electrode detection data by operators.

[0004] During the production of composite electrodes, random sampling inspection is required to ensure that the yield rate of composite electrodes reaches or exceeds the qualified line. Although the device in the aforementioned patent improves the electrode detection efficiency, it does not mark abnormal electrodes, making it difficult to distinguish abnormal electrodes. Therefore, we provide a testing device that facilitates quick replacement of composite electrodes to solve the above problems. Summary of the Invention

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.

[0024] This invention provides a technical solution for a testing device that facilitates quick replacement of composite electrodes.

[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The workbench 1 is equipped with a testing mechanism 3 in the middle. The testing mechanism 3 includes a fixed plate 301, a test cylinder 305 and a limiting plate 307. The test cylinder 305 is slidably connected to the workbench 1. The fixed plate 301 and the limiting plate 307 are used to position and fix the composite electrode, and the test cylinder 305 is used to test the composite electrode, thereby improving the convenience of composite electrode testing.

[0027] The connecting rod 403 and the limiting plate 307 fix the snap-fit ​​block 404 in multiple directions, improving the stability of the electrical connection between the detection connector 405 and the composite electrode contact. The detection connector 405 analyzes and transmits test data of the composite electrode, improving the accuracy of composite electrode detection. The clamping frame 401 clamps and fixes the composite electrode, making the contact between the detection connector 405 and the composite electrode tighter.

[0028] The surface of the workbench 1 is fixedly connected to a support tube 302, and the fixed plate 301 is rotatably connected to the support tube 302. The support tube 302 is used to position the fixed plate 301 and improve the stability of the rotation of the fixed plate 301.

[0029] The support tube 302 is rotatably connected to a rotating shaft 303, and the top end of the rotating shaft 303 is fixedly connected to a fixed disk 301. The workbench 1 is fixedly connected to a motor 304 that controls the rotation of the rotating shaft 303. The rotating shaft 303 is controlled to rotate by the motor 304, so that the rotating shaft 303 drives the fixed disk 301 to rotate, and moves the composite electrode to the top of the test tube 305.

[0030] A connecting block 309 is fixedly connected to the surface of the fixed disk 301, and a connecting sleeve 308 is fixedly connected to the middle of the limiting disk 307. The connecting sleeve 308 is inserted into the connecting block 309. The connecting block 309 and the connecting sleeve 308 are inserted together to limit the limiting disk 307 and prevent the limiting disk 307 from sliding up and down.

[0031] The workbench 1 is internally fixedly connected to a first electric push rod 306, and the output end of the first electric push rod 306 is fixedly connected to the test cylinder 305. The test cylinder 305 is moved up and down by the first electric push rod 306, so that the test cylinder 305 is sleeved on the outside of the composite electrode above. The composite electrode is tested through the test connector 405, which improves the convenience of composite electrode testing.

[0032] Please refer to it again. Figure 2 and Figure 4 The surface of the fixed plate 301 is provided with a circumferentially arranged fixing mechanism 4. The fixing mechanism 4 includes a clamping frame 401 and a detection connector 405. The surface of the clamping frame 401 is fixedly connected to a connecting rod 403 and a sliding rod 406, and the sliding rod 406 is slidably connected to the fixed plate 301. The top end of the connecting rod 403 is engaged with a locking block 404, which is fixedly connected to the detection connector 405, and one end of the locking block 404 is engaged with a limiting plate 307.

[0033] The clamping frame 401 is internally fixedly connected to a fixing clamp 402. A telescopic spring 408 is provided on the surface of the sliding rod 406, and the two ends of the telescopic spring 408 are fixedly connected to the fixing plate 301 and the sliding block 407 respectively. The fixing clamp 402 is used to clamp and limit the composite electrode to prevent the composite electrode from sliding up and down, thereby improving the stability of the composite electrode test. The telescopic spring 408 provides a pushing force to the sliding block 407, so that the sliding rod 406 controls the clamping frame 401 to stay inside the fixing plate 301, thereby improving the stability of the composite electrode test.

[0034] The clamping frame 401 is slidably connected to the fixed disk 301. The other end of the sliding rod 406 is fixedly connected to the sliding block 407. The sliding block 407 is slidably connected to the fixed disk 301, and the pull rod 5 is adapted to the adjacent sliding block 407. The sliding block 407 is moved by the pull rod 5, so that the sliding rod 406 pushes the clamping frame 401, pushes the abnormal composite electrode out of the fixed disk 301, and makes the abnormal composite electrode fall into the waste bin 2, thereby improving the sorting of composite electrodes.

[0035] Please refer to it again. Figure 4 A pull rod 5 is slidably connected to the middle of the support tube 302. A second electric push rod 6 is fixedly connected inside the support tube 302, and the output end of the second electric push rod 6 is fixedly connected to the pull rod 5. The second electric push rod 6 controls the movement of the pull rod 5, which drives the nearby sliding block 407 to move, pushing the abnormal composite electrode out of the fixed plate 301, so as to facilitate the sorting out of the abnormal composite electrode.

[0036] The motor 304, test cylinder 305, first electric push rod 306, detection connector 405 and second electric push rod 6 are all electrically connected to the controller on the surface of the workbench 1. The motor 304, test cylinder 305, first electric push rod 306, detection connector 405 and second electric push rod 6 are all existing equipment. The detailed parameters and models of these devices will not be described in detail in this application.

[0037] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0038] In use, the composite electrode is first placed in the middle of the fixing clamp 402, and then connected together by the connecting block 309 and the connecting sleeve 308, so that the detection connector 405 is electrically connected to the composite electrode contact. The rotating shaft 303 is controlled to rotate by the motor 304, which in turn drives the fixing disk 301 to rotate, moving the composite electrode directly above the test cylinder 305. The test cylinder 305 is then moved upward by the first electric push rod 306, so that the test cylinder 305 is fitted over the composite electrode above. After the detection connector 405 is connected, the composite electrode is tested. The head 405 tests the composite electrode. After the test is completed, the first electric push rod 306 retracts the test cylinder 305 into the workbench 1. When the composite electrode is abnormal, the second electric push rod 6 controls the pull rod 5 to move, which drives the sliding block 407 to move outward. The sliding rod 406 pushes the clamping frame 401 to push the abnormal composite electrode out of the fixed plate 301, so that the abnormal composite electrode falls into the waste bin 2. The abnormal composite electrode is sorted out, which facilitates the re-inspection of the abnormal composite electrode and improves the accuracy and convenience of composite electrode testing.
