Description

Technical Field

[0001] This invention relates to the field of automated experimental equipment and electrochemical testing technology, and in particular to an automated electrolytic cell assembly and enhanced lifespan testing system for electrode materials. Background Technology

[0002] Coated titanium anodes are widely used in chlor-alkali chemical, water treatment, hydrometallurgical, and new energy electrochemical processes. Their service stability typically requires evaluation through enhanced life testing. In high-throughput material screening, the life test results of a single sample depend not only on the electrode material itself but also significantly on the assembly state of the electrolytic cell and the consistency of testing conditions. Existing electrode life testing methods largely rely on manual assembly, which can easily lead to titanium sheet positioning deviations, inconsistent clamping forces, and differences in sealing conditions, thus affecting the effective exposed area of ​​the electrode and test stability. Factors such as electrolyte evaporation, temperature rise, and liquid level changes during testing can also affect the comparability between different samples. To address these issues, this invention provides an automated electrolytic cell assembly and enhanced life testing system for electrode materials. Summary of the Invention

[0003] To address the problems of poor consistency in manual assembly, difficulty in standardizing testing conditions, and low efficiency in the connection between assembly and testing processes in existing electrode life testing, this invention provides an automated electrolytic cell assembly and enhanced life testing system for electrode materials.

[0004] The present invention provides an automated electrolytic cell assembly and enhanced life testing system for electrode materials, which is achieved through the following technical solution: An automated electrolytic cell assembly and enhanced life testing system for electrode materials includes an assembly cabinet and a test cabinet connected to the assembly cabinet.

[0006] Preferably, titanium anode components are loaded onto the titanium anode component carrier tray located on the lower conveyor line. The titanium anode component carrier tray is transferred to the transfer platform of the first lifting and transferring component via the lower conveyor line. The first lifting and transferring component raises the titanium anode component carrier tray until it is parallel to the upper conveyor line. Then, the first lifting and transferring component transfers the titanium anode component carrier tray parallel to the upper conveyor line. A six-axis collaborative robot picks up the titanium anode components from the titanium anode component carrier tray and loads them onto the first station of the four-station rotary table. The upper conveyor line transfers the empty titanium anode component carrier tray parallel to the transfer platform of the second lifting and transferring component. The second lifting and transferring component lowers the titanium anode component carrier tray until it is parallel to the lower conveyor line. The second lifting and transferring component transfers the titanium anode component carrier tray parallel to the lower conveyor line, completing the titanium anode component loading closed loop.

[0054] refer to Figure 8 The peristaltic pump 325 is fixedly connected to the pure water storage tank at one end via a hose, and detachably and fixedly connected to the liquid inlet pipe of the titanium anode component in the product under test via a hose at the other end, so as to automatically replenish pure water, maintain the consistency of liquid level, and improve the accuracy of life test.

[0055] refer to Figure 1 The beaker fixture unloading line 33 is fixedly connected to the conveyor line B331 of the testing platform 100 and the beaker fixture B332, which can move linearly with the conveyor line B331. One end of the conveyor line B331 is located inside the testing cabinet 10, and the other end is located outside the testing cabinet 10. After the product has completed the test, it is placed in the beaker fixture B332 by the mobile robot component 31. The linear movement of the conveyor line B331 transfers the beaker fixture B332 from inside the testing cabinet 10 to outside the testing cabinet 10, where the operator removes the product after the test.

[0056] Automated workflow for an automated electrolytic cell assembly and enhanced life testing system for electrode materials: 1. Titanium anode component loading: Titanium anode components are loaded onto the titanium anode component carrier pallet 214 located on the lower conveyor line 2121 (the titanium anode components are manually placed to fill all four pallets of the titanium anode component carrier pallet 214). The fully loaded titanium anode component carrier pallet 214 is transferred via the lower conveyor line 2121 to the transfer platform 215 of the first lifting and transferring assembly 211. The first lifting and transferring assembly 211 raises the titanium anode component carrier pallet 214 until it is parallel to the upper conveyor line 2122. Subsequently, the first lifting and transferring assembly 211 transfers the titanium anode component carrier pallet 214 parallel to the upper layer. Conveyor line 2122 assembles a six-axis collaborative robot 25 to grasp titanium anode components on a titanium anode component carrier tray 214 and load the titanium anode components onto the first station of a four-station rotary turntable 22. The upper conveyor line 2122 transports the empty titanium anode component carrier tray 214 in parallel to the transport platform of the second lifting and transport assembly 213. The second lifting and transport assembly 213 descends so that the titanium anode component carrier tray 214 is parallel to the lower conveyor line 2121. The second lifting and transport assembly 213 then transports the titanium anode component carrier tray 214 in parallel to the lower conveyor line 2121, completing the titanium anode component loading closed loop. 2. Titanium Sheet Grabbing and Assembly: The four-station rotary turntable 22 is driven by a servo motor to rotate precisely 90° to the next station (i.e., the second station). The titanium sheet that has completed XRF testing in the XRF automated testing system is transferred by the robot arm in the XRF automated testing system to the titanium sheet placement slot of the titanium sheet loading platform 2312. The titanium sheet loading platform 2312 is linearly transferred to the assembly cabinet 1 through the X-axis linear module 231. That is, it moves from the test platform of the XRF automated testing system to the assembly cabinet 1. The vacuum adsorption end effector 233 of the titanium sheet transfer module 232 grabs the titanium sheet from the titanium sheet loading platform 2312. Then, the vacuum adsorption end effector 233 moves along the Y-axis to directly above the titanium anode sub-component loaded on the second station of the four-station rotary turntable 22. The vacuum adsorption end effector 233 moves along the Z-axis, and the titanium sheet moves downward, accurately placing the titanium sheet into the titanium anode sub-component loaded on the second station of the four-station rotary turntable 22, realizing the automated assembly of the titanium sheet into the titanium anode sub-component. 3. Protective cover loading and torque tightening: The four-station rotary table 22 rotates 90° again to the next station, the third station. The protective cover tightening device 24 actively picks up a single protective cover from the protective cover feeding assembly 241 through the torque tightening gun 243 and places it directly above the titanium sheet loaded on the second station of the four-station rotary table 22. The Z-axis linear module C242 drives the torque tightening gun 243 to press down. The set torque of 4~8 N•m is dynamically judged by feedback. After the target is met, the tightening automatically stops. The protective cover is tightened to the titanium sheet to obtain the finished titanium anode.

[0057] 4. Assembly and beaker assembly: After the tightening action is completed, the four-station rotary table 22 rotates 90° to the unloading station (fourth station); the operator loads the beaker onto the beaker fixture A262 located outside the assembly cabinet 1. The beaker fixture A262 carrying the beaker moves linearly along the conveyor line A261 to the inside of the assembly cabinet 1 to reach the handover position. The four-station rotary table 22 rotates 90° to the unloading station (fourth station). The three-jaw pneumatic gripper 251 of the six-axis collaborative robot 25 grabs the finished titanium anode that has been assembled on the fourth station of the four-station rotary table 22. The finished titanium anode is placed into the beaker on the beaker fixture A262 at the handover position to form an overall test product. 5. System Collaborative Transfer and Testing: The six-axis collaborative robot 312 moves along the X-axis linear module D311 to one end of the nearest conveyor line A261. The self-locking pneumatic gripper 313 of the mobile robot component 31 picks up the test product (finished titanium anode + beaker fixture) from the beaker fixture A262. After picking it up, it moves along the X-axis linear module D311, and the six-axis collaborative robot 312 transfers the test product and precisely places it in an idle independent testing station 32 for electrochemical testing. During testing at the testing station 32, the electrode tab docking mechanism 321 automatically connects and powers on the electrodes under the drive of cylinder A3210; the PT100 RTD 322 is powered by cylinder B3220. Driven by a device, the device extends into the beaker of the product under test to detect the temperature of the liquid inside the beaker and provide real-time feedback on the solution temperature. When the temperature fed back by the PT100 RTD 322 is higher than the set temperature, the cooling fan 323 starts to cool the liquid. When the temperature fed back by the PT100 RTD 322 is lower than or equal to the set temperature, the cooling fan 323 stops. The magnetic stirrer 326 is turned on to stir and mix the liquid in the beaker of the product under test. The liquid level detector 324 is used to detect the liquid level in the beaker of the product under test. The peristaltic pump 325 automatically adds pure water to maintain the consistency of the liquid level in each beaker of the product under test. The mobile robot component 31 cyclically performs the subsequent product grabbing, loading, and life test. 6. Test Outbound and Manual Unloading: After the electrochemical test is completed, the six-axis collaborative robot 312, through the coordinated transport of the seventh axis 311, takes out the product clamp that has completed the life test from the independent test station 32. The six-axis collaborative robot 312 moves along the X-axis linear module D311 to one end of the nearby conveyor line B331. The six-axis collaborative robot 312 places the product that has completed the life test securely on the beaker fixture B332 in the handover position in the beaker fixture unloading line 33. The linear movement of the conveyor line B331 transfers the beaker fixture B332 from inside the test cabinet 10 to outside the test cabinet 10. The operator removes the product that has completed the test after moving to outside the test cabinet 10 and is located on the beaker fixture B332, completing the closed-loop operation of the whole process.
