Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid electrolyte detection technology, specifically to a single-station detection device. Background Technology
[0002] Solid electrolytes are solid materials that replace traditional liquid electrolytes in batteries. They have ionic conductivity, high mechanical strength, thermal stability, and chemical compatibility. The core advantages of solid electrolytes include suppressing lithium dendrite growth, improving battery safety, and supporting higher energy density settings for batteries. Their performance directly affects the safety and lifespan of the battery.
[0003] Existing solid electrolyte testing relies on manual methods. The solid electrolyte is held in a mold, and a test force is applied by tapping the solid electrolyte with the help of a tool. In this process, the inventors found that it is difficult to control the amount of test pressure applied to the solid electrolyte manually. The uneven distribution of pressure can lead to discrepancies in the test results and affect the accuracy of the test results. Utility Model Content
[0004] Based on the above description, this utility model provides a single-station testing device to solve the problem that when solid electrolytes are tested manually, the magnitude of the applied test pressure is difficult to control, the pressure distribution is uneven, and the accuracy of the solid electrolyte test results is affected.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A single-station testing device includes a base, a transmission component mounted on the surface of the base, and a test chamber containing a solid electrolyte. A test column that slides vertically relative to the test chamber is mounted on the outside of the transmission component. The test column forms a clamping test by vertically sliding with the test chamber.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, the transmission assembly includes a limiting rod, a support, a servo motor, a coupling, a lead screw, and a slider. The limiting rod is fixedly connected to the surface of the base and is symmetrically distributed with the center of the base as the origin. The support is fixedly connected to the end of the limiting rod away from the base, and the lead screw is rotatably connected between the support and the two sides of the base that are close to each other.
[0008] Furthermore, the servo motor is installed on the side of the support away from the base, the output end of the servo motor faces the base, the coupling is installed between the output end of the servo motor and the lead screw, and the slider is installed on the outside of the lead screw.
[0009] Furthermore, a slide table is fixedly connected to the outside of the slider, and the two ends of the slide table wrap around the limiting rod and are slidably connected to the outside of the limiting rod. A threaded seat is installed on the side of the slide table near the base, and the test column is threadedly connected to the outside of the threaded seat.
[0010] Furthermore, the surface of the test chamber is provided with a first terminal, and a boss is fixedly connected to one end of the test chamber near the test column. The boss surrounds the test chamber in a ring shape, and a heating coil is installed inside the boss. An instantaneous touch switch facing the test column is embedded on the surface of the boss.
[0011] Furthermore, the test column is convex in shape, and an annular groove is provided at one edge of the surface of the test column. A sleeve is slidably connected in the annular groove. A return spring is fixedly connected between one end of the inner wall of the sleeve and the test column. A contact head is installed at the end of the sleeve near the base.
[0012] Furthermore, the input terminal of the instantaneous touch switch is connected to a second terminal, which passes through the boss and extends to the outside. The output terminal of the instantaneous touch switch is connected to the input terminal of the heating coil.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0014] 1. This utility model uses a test column that moves vertically on the outside of the transmission assembly, in conjunction with the test chamber. Driven by a servo motor, the test column moves vertically relative to the test chamber to form an automated clamping mechanism, replacing the inefficiency of manual labor. The servo motor can apply a fixed pressure to the clamping of the test column and the test chamber, and the pressure distribution is uniform, reducing human error and increasing the accuracy of solid electrolyte quality testing.
[0015] 2. This utility model uses a sleeve and a return spring, along with a heating coil and a momentary touch switch. During the vertical movement of the test column and its clamping and separation from the test chamber, the sleeve can also synchronously contact and separate from the momentary touch switch to form power on and off. When powered on, the heating coil starts to heat the test chamber, simulating a more realistic solid electrolyte usage environment, making the solid electrolyte conductivity detection data more accurate. When the test column separates from the test chamber, the heating coil is de-energized, saving resource consumption. Attached Figure Description

Detailed Implementation
[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0025] Please see Figures 1-5 The present invention provides a single-station testing device, comprising a base 1, a transmission assembly 2 mounted on the surface of the base 1, and a test chamber 7 containing a solid electrolyte. A test column 4 is mounted on the outside of the transmission assembly 2 and slides vertically relative to the test chamber 7. The test column 4 forms a clamping test by sliding vertically with the test chamber 7.
[0026] Please see Figure 2The transmission assembly 2 includes a limiting rod 21, a support part 22, a servo motor 23, a coupling 24, a lead screw 25, and a slider 26. The limiting rod 21 is fixedly connected to the surface of the base 1 and is symmetrically distributed with the center of the base 1 as the origin. The support part 22 is fixedly connected to the end of the limiting rod 21 away from the base 1. The lead screw 25 is rotatably connected between the support part 22 and the two sides of the base 1 that are close to each other. The symmetrically distributed limiting rod 21 provides bidirectional rigid support. When the slide table 3 moves vertically outside the lead screw 25 via the slider 26, the limiting rod 21 can prevent the slide table 3 from rotating due to inertia. It can also prevent the test column 4 from being laterally loaded due to the resistance of the solid electrolyte when the lead screw 25 is in transmission, thus ensuring the stability of the test column 4 when it is docked and clamped with the test chamber 7.
[0027] Please see Figure 2 The servo motor 23 is installed on the side of the support 22 away from the base 1, with the output end of the servo motor 23 facing the base 1. The coupling 24 is installed between the output end of the servo motor 23 and the lead screw 25. The slider 26 is installed on the outside of the lead screw 25. The servo motor 23 is directly connected to the lead screw 25 through the coupling 24, eliminating transmission chain gaps and ensuring that there is no impact when the test column 4 contacts the solid electrolyte. The servo motor 23 enables adaptive speed adjustment of the test column 4 and can apply a fixed pressure to clamp the test column 4 and the test chamber 7. The pressure distribution is uniform, reducing human error and increasing the accuracy of solid electrolyte quality testing. The servo motor 23 can also apply different pressures for solid electrolyte testing, increasing the data sample size for solid electrolyte testing.
[0028] Please see Figure 2 A slide table 3 is fixedly connected to the outside of the slider 26. The two ends of the slide table 3 are wrapped with limiting rods 21 and slidably connected to the outside of the limiting rods 21. A threaded seat 31 is installed on the side of the slide table 3 near the base 1. The test column 4 is threadedly connected to the outside of the threaded seat 31. The standardized interface of the threaded seat 31 supports the quick replacement of test columns 4 of different diameters, adapting to the testing needs of multiple specifications of solid electrolytes. The linkage design between the slide table 3 and the slider 26 isolates motor vibration. The servo motor 23 drives the lead screw 25 to rotate. The slider 26 on the outside of the lead screw 25 drives the slide table 3 to move vertically along the limiting rod 21 and form a clamp with the test chamber 7. It can test the conductivity of solid electrolytes and can also be adapted to test diaphragm and liquid electrolytes. The detection is automated, replacing the low efficiency of manual labor.
[0029] Please see Figure 5The test chamber 7 has a first terminal 71 on its surface. A boss 8 is fixedly connected to the outer side of the test chamber 7 near the test column 4. The boss 8 encircles the test chamber 7 in a ring shape. A heating coil 81 is installed inside the boss 8. An instantaneous touch switch 82 facing the test column 4 is embedded on the surface of the boss 8. When the test column 4 contacts the solid electrolyte, the instantaneous touch switch 82 contacts the contact head 51 to automatically start and stop heating, avoiding the heating coil 81 from heating under no-load and causing energy consumption. The heating coil 81 heats the test chamber 7, simulating a more realistic solid electrolyte usage environment, making the solid electrolyte test data more realistic. The first terminal 71 on the outer side of the test chamber 7 can be connected to the test system to upload the conductivity test results of solid electrolyte, liquid electrolyte or diaphragm. The test chamber 7 is installed on the surface of the base 1 by a threaded connection. The standardized interface supports different settings and allows for the replacement of test chambers 7 of different shapes.
[0030] Please see Figure 4 The test column 4 is convex in shape, and an annular groove 41 is provided on one edge of the surface of the test column 4. A sleeve 5 is slidably connected in the annular groove 41. A return spring 6 is fixedly connected between one end of the inner wall of the sleeve 5 and the test column 4. A contact head 51 is installed on the end of the sleeve 5 near the base 1. During the process of the test column 4 clamping the solid electrolyte with the test chamber 7, the contact head 51 on the outside of the sleeve 5 will contact the momentary touch switch 82, so that the heating coil 81 is energized to heat the test chamber 7. At the same time as the contact head 51 on the outside of the sleeve 5 contacts the momentary touch switch 82, the sleeve 5 will also press the return spring 6 to retract into the annular groove 41. When the thickness of the solid electrolyte increases, the overall thickness of the test chamber 7 and the test column 4 will also change. The return spring 6 will adapt to the thickness of the solid electrolyte, so that the sleeve 5 retracts into the annular groove 41 to different depths, automatically adapting to the clamping of solid electrolytes of different thicknesses.
[0031] Please see Figure 2 The input terminal of the instantaneous touch switch 82 is connected to the second terminal 9, which passes through the boss 8 and extends to the outside. The output terminal of the instantaneous touch switch 82 is connected to the input terminal of the heating coil 81. The signal of the instantaneous touch switch 82 is directly connected to the heating coil 81 through the second terminal 9, which has low trigger delay and quickly maintains the constant temperature of the solid electrolyte. The second terminal 9 can also be connected to an external PLC or temperature control instrument to realize PID adjustment of heating power and adapt to the temperature curve requirements of different solid electrolytes.
