[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figures 1-6 As shown in the illustration, this application discloses a testing device for a composite electrode, including a base 10, a test platform 20, and disassembly components 30. A controller 11 and a display screen 12 are disposed on one side of the base 10. The test platform 20 is mounted on the base 10, and solution cups 13 are disposed on both sides of the test platform 20, for storing standard solutions. Two sets of test connectors 21 are provided on the test platform 20, with two connectors in each set. Two disassembly components 30 are provided on the test platform 20, each corresponding to one of the two sets of test connectors 21. During testing, the operator screws the connectors of the two composite electrodes onto one set of test connectors 21, and then immerses the detection portion of the composite electrode in the standard solution in the solution cup 13. Next, screw the connectors of the other two composite electrodes onto another set of test connectors 21. Then, immerse the test section in the standard solution in another solution cup 13. At this time, the first set of test connectors 21 receives data and transmits it to the controller 11, which is then displayed on the display screen 12, completing the test. The operator then activates the disassembly component 30 to disconnect the connector. Subsequently, screw the connectors of the next composite electrode to be tested onto this set of test connectors 21. At this time, the other set of test connectors 21 completes the test and displays the data on the display screen 12. This alternating operation allows the operator to disassemble and assemble the other set of composite electrodes and perform subsequent steps while one set of composite electrodes is being tested, reducing waiting time and improving testing efficiency. The controller 11 has two buttons, which control the two disassembly components 30 respectively.

[0029] Specifically, the disassembled component 30 includes a lifting plate 31, a lifting unit 40, and a drive unit 50. The lifting plate 31 is vertically slidably mounted on the test bench 20. The test bench 20 has a vertically opening sliding hole 22, and a sliding rod 23 is slidably mounted inside the sliding hole 22. The top of the sliding rod 23 is connected to the bottom of the lifting plate 31 to ensure the stability of the lifting plate 31 during lifting. The lifting unit 40 is mounted on the test bench 20 and is used to drive the lifting plate 31 to lift. The lifting plate 31 has two openings spaced apart, corresponding to the test connector 21. A rotating tube 32 is vertically rotatably mounted inside the opening, and a rubber ring 33 is installed inside the rotating tube 32. The lifting plate 31 is equipped with a drive unit 50 that drives the rotating tube 32 to rotate. The lifting unit 40 drives the lifting plate 31 to rise, while the driving unit 50 drives the rotating tube 32 to rotate, causing the rubber ring 33 to rotate. After the rubber ring 33 rises and fits onto the socket, several protrusions on the outer wall of the socket abut against the inner wall of the rubber ring 33, causing the rubber ring 33 to rotate and drive the socket to rotate. The lifting unit 40 continues to drive the lifting plate 31 to rise, causing the socket to be unscrewed and separated from the test connector 21. The operator pulls the socket out of the rubber ring 33 for subsequent processing, eliminating the step of unscrewing the socket from the test connector 21 and reducing operator hand fatigue. The inner diameter of the rubber ring 33 is the same as the outer diameter of the socket, ensuring strong friction between the inner wall of the rubber ring 33 and the outer wall of the socket and the protrusions, ensuring that the plug can rotate. The top edge of the inner wall of the rubber ring 33 has a chamfer 34 to facilitate the fitting of the rubber ring 33 onto the socket. The outer wall of the rubber ring 33 has an annular groove 35, and a retaining ring 36 is provided in the annular groove 35. The retaining ring 36 provides support for the rubber ring 33, reduces the deformation of the rubber ring 33, and ensures the stability of the contact between the inner wall of the rubber ring 33 and the outer wall of the socket and the protrusion.

[0030] In its configuration, the drive unit 50 includes a driven pulley 51 fixedly sleeved on the rotating tube 32. A drive motor 52 is vertically mounted on the lifting plate 31. The output axis of the drive motor 52 passes upward through the lifting plate 31 and has a drive pulley 53 mounted thereon. The drive pulley 53 is connected to the two driven pulleys 51 via a transmission belt 54. The drive motor 52 drives the drive pulley 53 to rotate. Since the drive pulley 53 is connected to the two driven pulleys 51 via the transmission belt 54, the rotation of the driven pulleys causes the rotating tube 32 to rotate. A tensioning wheel can be rotatably mounted on the lifting plate 31 to ensure the stability of the transmission belt 54.

[0031] In the specific setup, the test bench 20 has a mounting slot 24 in the middle. The lifting unit 40 includes a fixed plate 41 set at the top of the mounting slot 24 wall. A threaded rod 42 is rotatably connected between the fixed plate 41 and the bottom of the mounting slot 24. The upper end of the threaded rod 42 is rotatably connected to the fixed plate 41, and the lower end is rotatably connected to the bottom of the mounting slot 24. Two upright plates 43 are spaced apart at the bottom of the lifting plate 31 at the opening of the mounting slot 24. A connecting block 44 is provided at the bottom of the two upright plates 43. The connecting block 44 is screwed to the threaded rod 42 through a threaded hole, so that when the threaded rod 42 rotates, it can drive the connecting block 44 to rise and fall, thereby driving the upright plates 43 and the lifting plate 31 to rise and fall. A rotating lifting motor 45 is vertically installed at the bottom of the test bench 20. The output shaft of the lifting motor 45 passes upward through the bottom of the test bench 20 and is connected to the end of the threaded rod 42. The lifting motor 45 drives the threaded rod 42 to rotate.

[0032] The working principle of the test device for a composite electrode in this embodiment is as follows: During the test, the operator screws the two composite electrode sockets onto one of the test connectors 21, and then immerses the detection part of the composite electrode in the standard solution in the solution cup 13. Next, screw the sockets of the other two composite electrodes onto another set of test connectors 21. Then, immerse the test part in the standard solution in another solution cup 13. At this time, the test connectors 21 of the first set receive data and transmit it to the controller 11, which is then displayed on the display screen 12, completing the test. The operator presses the button to start the drive motor 52 and the lifting motor 45 corresponding to this set of test connectors 21. The lifting motor 45 drives the threaded rod 42 to rotate, causing the connecting block 44, the upright plate 43, and the lifting plate 31 to rise. The drive motor 52 drives the active pulley 53 to rotate, causing the rotating tube 32 and the rubber ring 33 to rotate. After the rubber ring 33 rises and is fitted onto the socket, several protrusions on the outer wall of the socket abut against the inner wall of the rubber ring 33, causing the rubber ring 33 to rotate and drive the socket to rotate. The lifting motor 45 continues to drive the lifting plate 31 to rise, causing the socket to be unscrewed and separated from the test connector 21. The operator pulls the socket out of the rubber ring 33 for subsequent processing. The lifting motor 45 drives the lifting plate 31 to reset. Then, the connector of the composite electrode to be tested is screwed onto this set of test connectors 21. At this time, the other set of test connectors 21 completes the test and displays the data on the display screen 12. This alternating operation allows the staff to disassemble and install the other set of composite electrodes and perform subsequent steps while one set of composite electrodes is being tested, reducing the staff's waiting time and improving the testing efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
