[0038] As Figure 1 and Figure 2 The utility model discloses a material performance detection device, it includes frame 10, electronic scale 20, adapter piece 30, suspension assembly and lifting portion 50. In which electronic scale 20 includes the weighing plate, and adapter piece 30 is arranged on the weighing plate, and suspension assembly has oppositely arranged first connecting end and second connecting end, and first connecting end is detachably arranged on adapter piece 30, and second connecting end extends downward, and second connecting end is used for connecting or containing the material to be tested, and lifting portion 50 is located below second connecting end of suspension assembly, and the top of lifting portion 50 is provided with container 51 for containing liquid, and the liquid is used for infiltrating the material to be tested, so that electronic scale 20 weighs the weight of the material to be tested infiltrated by liquid.

[0039] The technical scheme of the utility model can test the infiltration performance of the material to be tested, and as the test is carried out, when the liquid level in container 51 drops, container 51 can be lifted by lifting portion 50 to ensure that the bottom end of the material to be tested is always infiltrated in the solution during the test. Moreover, through the device of the scheme, the height of container 51 is adjusted by lifting portion 50 during the test to adjust the height of the liquid level in container 51, and the position of electronic scale 20 and the material to be tested is always unchanged, so that the possibility of shaking of electronic scale 20 is avoided, and the accuracy of the test of the device is improved. In addition, suspension assembly is installed on electronic scale 20 through adapter piece 30, which can improve the convenience of connecting suspension assembly and electronic scale 20.

[0040] Moreover, in the prior art, when testing the infiltration effect of a powder material by the immersion weighing method, the staff may hold the filter screen cylinder to test the mass of the powder in the filter screen cylinder before the filter screen cylinder is immersed in the electrolyte, immerse the filter screen cylinder in the electrolyte by holding the filter screen cylinder, take out the filter screen cylinder after a specific time of immersion, and test the mass of the powder in the filter screen cylinder again. Compared with the staff holding the filter screen cylinder, the operation is more convenient and the accuracy is higher.

[0041] The specific form of the suspension assembly is not limited in the present solution, as long as it can connect or contain the material to be tested.

[0042] It is worth noting that the present device can test the infiltration performance of sheet materials such as pole pieces and diaphragms, and can also test the infiltration performance of powder materials of positive and negative electrode materials.

[0043] In some application scenarios, the present device can test the infiltration performance of powder materials. At this time, the suspension assembly includes a first suspension assembly 41, and the second connecting end of the first suspension assembly 41 includes a containing portion 4101. In the vertical direction, the projection of the containing portion 4101 is located in the container 51, and the containing portion 4101 can be embedded or taken out of the container 51. When the infiltration performance test is needed, the bottom end of the containing portion 4101 can be embedded in the container 51 to make the powder material fully contact with the liquid, and the infiltration test can be realized. During the test, after the liquid level in the container 51 drops, the height of the container 51 is raised by the lifting portion 50, so that the bottom of the containing portion 4101 is always immersed in the liquid, thereby ensuring the accuracy and continuity of the test. When the test is completed or the material needs to be replaced, the containing portion 4101 can be taken out of the container 51 to facilitate subsequent operations.

[0044] In the present embodiment, the containing portion 4101 includes a measuring cylinder and a filter screen cylinder, and the top of the measuring cylinder is an open structure. The top of the filter screen cylinder is also an open structure. The measuring cylinder and the filter screen cylinder are respectively detachably connected with the main body portion of the suspension assembly. It can be understood that the top of the measuring cylinder and the top of the filter screen cylinder are both open structures, and are respectively detachably connected with the second connecting end of the first suspension assembly 41. In this way, the measuring cylinder or the filter screen cylinder can be used according to different needs.

[0045] Specifically, when the infiltration performance of the powder material needs to be tested, the filter screen cylinder is used for testing. The mesh structure of the filter screen cylinder enables the liquid to fully contact with the powder material. During the test, the bottom end of the filter screen cylinder is immersed in the liquid. Due to the surface tension of the liquid and the adsorption of the powder material, the liquid will be infiltrated in the powder material. Through the numerical change of the electronic scale, the liquid absorption mass of the infiltrated powder material can be obtained, and then the infiltration performance of the powder material within a specific time can be obtained. The greater the infiltration mass, the stronger the adsorption ability of the powder material to the liquid, and the better the infiltration performance.

[0046] Specifically, when the density of the powder material needs to be tested, a measuring cylinder is used for testing. As a commonly used measuring container, the measuring cylinder has accurate scales and can accurately measure the volume of the powder material. By loading a certain mass of powder material into the measuring cylinder, measuring its volume, and then calculating the density value according to the density formula, accurate data support can be provided for the quality control and performance evaluation of the powder material.

[0047] In the embodiment of the present scheme, the bottom end of the main body part of the first suspension assembly 41 includes a semi-annular clamping bracket, and the open end of the measuring cylinder and the filter screen cylinder each has an outwardly bent flange. When assembling, the flange of the measuring cylinder or the filter screen cylinder is clamped at the clamping bracket.

[0048] As shown in Figure 3 In some application scenarios, the device can test the wettability of sheet materials such as pole pieces and diaphragms. At this time, the suspension assembly includes a second suspension assembly 42, and the second connecting end of the second suspension assembly 42 includes a clamping part 4201 for clamping the top end of the material to be tested. By clamping the top end of the material to be tested through the clamping part 4201, stable clamping of the sheet material can be achieved, ensuring the position of the material fixed during the test, thereby improving the accuracy and reliability of the test.

[0049] Specifically, the clamping part 4201 can be adjusted according to the thickness and shape of the material to adapt to different specifications of sheet materials, ensuring that the material always remains in the best position during the wettability test, avoiding test errors caused by material shaking or position deviation. In addition, the design of the clamping part 4201 can also prevent the material from being damaged during the test, ensuring the integrity of the material, thereby providing reliable protection for subsequent testing and analysis.

[0050] In the embodiment of the present scheme, the clamping component 4201 comprises a fixed part 421 and a swing part 422. The fixed part 421 is fixedly arranged on the main body part of the second suspension assembly 42, and has a first clamping surface. The first end of the swing part 422 is hingedly arranged on the fixed part 421. The second end of the swing part 422 has a second clamping surface. The second end of the swing part 422 has a first position and a second position. When the second end of the swing part 422 is in the first position, the second clamping surface is close to the first clamping surface and cooperates with the first clamping surface to clamp the test material. When the second end of the swing part 422 is in the second position, the second clamping surface is away from the first clamping surface to release the clamping of the test material. When it is necessary to clamp the test material, the position of the second end of the swing part 422 is adjusted so that the second end of the swing part 422 is in the second position. At this time, the second clamping surface and the first clamping surface are in a separated state. Then, the top end of the test material is inserted between the second clamping surface and the first clamping surface. The position of the second end of the swing part 422 is adjusted so that the second clamping surface cooperates with the first clamping surface to clamp the top end of the test material. After the test is completed, the second end of the swing part 422 is adjusted from the first position back to the second position. The second clamping surface is away from the first clamping surface to release the clamping of the test material, which facilitates the taking out of the material or the replacement of the new test material. In this way, the first clamping surface and the second clamping surface are respectively in surface contact with the test material, which can avoid the situation that the test material is easily dropped when clamped by point-to-point, the test material is not uniformly stressed after clamping, and the possibility of the test material being not vertical and deviating laterally during clamping. The stability of clamping the test material is improved.

[0051] Further, the clamping component 4201 further comprises an execution part 423 and a transmission part 424 connected with each other, the transmission part 424 is connected with the fixed part 421 and the swing part 422 respectively, the execution part 423 drives the swing part 422 to swing through the transmission part 424 under the action of an external force, so as to switch the second end of the swing part 422 between the first position and the second position. When it is needed to clamp the material to be tested, the external force acts on the execution part 423, after the execution part 423 receives the external force, the power is transmitted to the swing part 422 through the transmission part 424, the swing part 422 is driven to swing, the second end of the swing part 422 moves from the second position to the first position, the second clamping surface is close to and contacts the first clamping surface, and the two cooperate to clamp the top end of the material to be tested. After the test is completed, the external force acts on the execution part 423 again, the execution part 423 drives the swing part 422 to swing through the transmission part 424, so that the second end of the swing part 422 moves from the first position to the second position, the second clamping surface is away from the first clamping surface, and the clamping of the material to be tested is released, which is convenient for taking out the material or replacing new test material. Through the setting of the execution part 423 and the transmission part 424, the operator only needs to apply the external force to the execution part 423, so as to realize the swing of the swing part 422, complete the clamping and releasing operation, and does not need to manually adjust the swing part 422, and the operation is more convenient.

[0052] In some embodiments of the present scheme, the execution part 423 can be manually applied with the force.

[0053] In some embodiments of the present scheme, the execution part 423 can be manually applied with the force.

[0054] Specifically, the swing part 422 includes a first segment 4221, a second segment 4222 and a clamping segment 4223 connected with each other, the first segment 4221 and the second segment 4222 have an included angle therebetween, the first segment 4221 and the second segment 4222 are hinged to the fixed part 421 at a position of connection therebetween, the first segment 4221 has a spacing from the first clamping surface, the second segment 4222 extends away from the first clamping surface, and the transmission part 424 is connected to an end of the second segment 4222 away from the first segment 4221; the clamping segment 4223 is arranged at an end of the first segment 4221 away from the second segment 4222, and the clamping segment 4223 extends toward the first clamping surface, and an end of the clamping segment 4223 away from the first segment 4221 forms a second clamping surface. The mutual connection and layout of the first segment 4221, the second segment 4222 and the clamping segment 4223 make the structure of the entire clamping component 4201 more compact, reduce the volume and occupied space of the device, and facilitate the miniaturization of the device, and facilitate installation and use in limited space.

[0055] In the embodiment of the present scheme, the extension direction of the first segment 4221 is perpendicular to the extension direction of the second segment 4222, the extension direction of the clamping segment 4223 is perpendicular to the extension direction of the first segment 4221, the second segment 4222 and the top of the first segment 4221 are of an integral molding structure, and the clamping segment 4223 and the bottom end of the first segment 4221 are detachably connected. In this way, the clamping segment 4223 can be replaced, so that the clamping segment 4223 is suitable for different materials to be tested.

This design provides high operation flexibility, so that the clamping component 4201 can adapt to materials to be tested of different sizes and shapes, and enhances the adaptability and flexibility of the device.

[0058] Further, the execution part 423, the transmission part 424 and the swing part 422 are located on the same side of the fixed part 421, and the execution part 423, the transmission part 424 and the swing part 422 are distributed along the height direction, so that the rationality and compactness of the design of the structure of the device are further improved.
