[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application.

[0034] Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0035] As described in the background art, when measuring the electrolyte infiltration rate using the suspension method in the related technical solutions, there are problems such as a fast electrolyte evaporation rate, low test efficiency, and lack of flexibility of the equipment. After research, it is found that the reasons for the above problems are as follows: in the test device of the related technology, the electrolyte is generally placed in the electrolyte tank, and the electrolyte tank is open, resulting in a large contact area between the electrolyte and the outside world, thus making the evaporation rate of the electrolyte relatively fast; there are certain limitations in the number of test samples of the existing equipment, and multiple samples cannot be tested simultaneously; when the lifting mechanism has problems, the equipment cannot be used for testing either.

[0036] In view of this, an embodiment of the present application aims to provide an infiltration device, which reduces the contact area between the electrolyte and the external environment by setting a tank cover to cover part of the opening of the electrolyte tank, which is beneficial to slowing down the volatilization rate of the electrolyte and improving the accuracy of the electrolyte infiltration rate test; when multiple samples need to be tested at the same time, the mounting rod can be extended and the number of fixings and electrolyte tanks can be increased as needed, which can improve the test efficiency; the positioning nut can determine the connection position of the support column and the adapter plate, so that the connection position can be manually adjusted to control the infiltration height of the fixing and the electrolyte. When an abnormality occurs in the lifting mechanism, the mode can be flexibly switched and experiments can also be carried out.

[0037] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail. It should be noted that in the description of the present application, the first direction X, the second direction Y, and the third direction Z are three different directions in a three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, and the third direction Z can be a vertical direction.

[0038] Please refer to Figures 1-6 , this embodiment provides an infiltration device, including a mounting bracket 100 and a containing structure 200 for containing electrolyte. Among them, the containing structure 200 includes an electrolyte tank 210 and a tank cover 220, and the electrolyte tank 210 can be prismatic or cylindrical, for example, in the shape of a rectangular parallelepiped. The electrolyte tank 210 is provided with an opening on one side of the third direction Z, and the tank cover 220 is arranged at the opening of the electrolyte tank 210 to shield the opening of the electrolyte tank 210, thereby reducing the contact area between the electrolyte tank 210 and the external environment and reducing the volatilization rate of the electrolyte. Exemplarily, the tank cover 220 can overlap the side wall of the electrolyte tank 210 to achieve shielding of the electrolyte tank 210. At least one fixing member 110 is provided on the mounting bracket 100, and the fixing member 110 is used to fix the product to be tested. When the number of products to be tested is large, the mounting rod 130 can be extended, and the number of fixing members 110 and electrolyte tanks 210 can be increased according to demand, so that the test efficiency can be improved. Exemplarily, the fixing member 110 is generally in the shape of a rectangular parallelepiped, and the fixing member 110 can be arranged on the mounting bracket 100 along the third direction Z. The fixing member 110 is arranged opposite to the containing structure 200 in the third direction Z. When there is a problem with the lifting mechanism 300, the support column 120 and the adapter plate 150 are fixed by the positioning nut 140, and the test height can be flexibly determined. When the lifting mechanism 300 is abnormal, the mode is switched, and the test can be carried out smoothly. The product to be tested can be, for example, a diaphragm, a positive electrode sheet or a negative electrode sheet.

[0039] like Figure 2As shown, in this embodiment, at least one through hole 221 is provided on the slot cover 220, and the mounting bracket 100 and / or the accommodating structure 200 are movable. For example, at least one of the mounting bracket 100 and the accommodating structure 200 can move along the third direction Z. When the mounting bracket 100 and / or the accommodating structure 200 move, the fixing member 110 can pass through the through hole 221 and contact the electrolyte in the accommodating structure 200, so that the product connected to the fixing member 110 is immersed in the electrolyte. Further, by measuring the diffusion length of the electrolyte on the product over a period of time, the rate of electrolyte immersion in the product can be obtained. It can be understood that the projected area of the through hole 221 in the plane parallel to the first direction X and the second direction Y is adapted to the projected area of the fixing member 110 and the product thereon in the plane parallel to the first direction X and the second direction Y. The projected area of the through hole 221 can be slightly larger than the projected area of the fixing member 110 and the product thereon to ensure that the fixing member 110 can smoothly pass through the through hole 221 while minimizing the area of the through hole 221 and reducing the evaporation rate of the electrolyte.

[0040] As can be seen from the above description, in this embodiment, by moving the mounting bracket 100 and / or the accommodating structure 200, the fixing member 110 is brought into contact with the electrolyte in the accommodating structure 200, thereby realizing the test of the electrolyte immersion rate. Since the slot cover 220 is provided at the opening of the electrolyte tank 210, the contact area between the electrolyte and the external environment is reduced, which is beneficial to slowing down the evaporation rate of the electrolyte and improving the accuracy of the electrolyte immersion rate test.

[0041] Please continue to refer to Figure 1 , the mounting bracket 100 of this embodiment includes two support columns 120 and a mounting rod 130. The two support columns 120 are arranged at intervals along the first direction X. The two support columns 120 are used to connect to the support table surface, and the support table surface can be the ground or a tabletop, etc. The two ends of the mounting rod 130 are respectively fixedly connected to the two support columns 120. The mounting rod 130 is generally arranged along the first direction X. The fixing member 110 is arranged on the mounting rod 130, for example, it can be arranged along the third direction Z on the side of the mounting rod 130 facing the electrolyte tank 210. The electrolyte tank 210 is located on the side of the mounting rod 130 facing the fixing member 110 in the third direction Z, and the electrolyte tank 210 is located between the two support columns 120 in the first direction X.

[0042] With the above structure, when the mounting bracket 100 and / or the accommodating structure 200 move along the third direction Z, it can be ensured that the fixing member 110 located above the electrolyte tank 210 passes through the through hole 221 and then inserts into the electrolyte tank 210, so that the product on the fixing member 110 contacts the electrolyte in the electrolyte tank 210 to perform the test of the electrolyte immersion rate.

[0043] Exemplarily, the two support columns 120 in this embodiment are movably arranged on the support tabletop. For example, the support column 120 can be provided with a support platform, the support platform is arranged at one end of the support column 120 along the third direction Z, and the projected area of the support platform in the plane parallel to the first direction X and the second direction Y can be larger than the projected areas of the remaining positions on the support column 120 in the plane parallel to the first direction X and the second direction Y. The support column 120 can be abutted against the support tabletop through the support platform. When it is necessary to move the support column 120, only need to pick up the support column 120 and then place it at the target position.

[0044] The mounting rod 130 includes a first rod body and a second rod body. The second rod body is inserted through the first rod body and can move relative to the first rod body. By pulling the second rod body, the length of the mounting rod 130 along the first direction X can be changed.

[0045] With the above structure, multiple fixing members 110 can be provided on the mounting rod 130 of this embodiment. The multiple fixing members 110 can fix the same type of product to simultaneously test multiple products, and the accuracy of the test results can be improved by calculating the average value of the electrolyte infiltration rates of the multiple products. Or, the multiple fixing members 110 can fix multiple different types of products, so as to realize the test of the electrolyte infiltration rates of multiple different products.

[0046] In a possible implementation manner, a plurality of connection grooves 131 are provided on the mounting rod 130 of this embodiment. The plurality of connection grooves 131 are arranged at intervals along the axial direction of the mounting rod 130 (i.e., along the first direction X). The fixing member 110 is detachably arranged in the connection groove 131 through a connecting member. Exemplarily, the connecting member can be a hook, and a corresponding fixing hole can be provided on the fixing member 110. After the hook passes through the fixing hole, it is connected to the connection groove 131 to suspend the fixing member 110 on the mounting rod 130. When it is necessary to remove the fixing member 110, only need to take out the hook from the connection groove 131. The connection between the fixing member 110 and the mounting rod 130 is convenient and fast, which is beneficial to saving the preparation time before the test.

[0047] In a possible implementation, this embodiment can make the fixing member 110 contact the electrolyte in the accommodating structure 200 by adjusting the height of the mounting bracket 100 (i.e., the position in the third direction Z). Specifically, a threaded section is provided on the support column 120 of this embodiment, and a positioning nut 140 is provided on the threaded section. The positioning nut 140 is fixedly connected to the threaded section, so that the positioning nut 140 can be fixed at a certain position along the third direction Z of the support column 120. Connecting plates 150 are connected to both ends of the mounting rod 130. The mounting rod 130 and the connecting plates 150 can be connected and fixed by welding or other means. The connecting plates 150 are sleeved on the support column 120 and abutted against the positioning nut 140. Exemplarily, through holes can be provided on the connecting plates 150, and the support column 120 passes through the through holes so that the connecting plates 150 are sleeved on the support column 120, and the connecting plates 150 can be abutted against the positioning nut 140, so that the mounting rod 130 is fixed at a certain position along the third direction Z.

[0048] It can be understood that when it is necessary to adjust the position of the mounting rod 130 in the third direction Z, the positioning nut 140 can be rotated to drive the connecting plate 150 to move along the third direction Z, and further make the mounting rod 130 connected to the connecting plate 150 move along the third direction Z.

[0049] In another possible implementation, this embodiment can make the fixing member 110 contact the electrolyte in the accommodating structure 200 by adjusting the height of the accommodating structure 200. Specifically, a lifting mechanism 300 is provided on the side of the electrolyte tank 210 away from the mounting rod 130. The lifting mechanism 300 is used to drive the electrolyte tank 210 to move towards or away from the fixing member 110. Exemplarily, the lifting mechanism 300 can be a pneumatic cylinder or a hydraulic cylinder. The piston rod of the pneumatic cylinder or the hydraulic cylinder abuts against the electrolyte tank 210, and the position of the electrolyte tank 210 in the third direction Z is changed by controlling the telescopic movement of the piston rod, so that the fixing member 110 contacts the electrolyte in the accommodating structure 200.

[0050] Please continue to refer to Figure 1 , the wetting device of this embodiment further includes a base 400. The surface of the base 400 facing the electrolyte tank 210 forms a support tabletop. The lifting mechanism 300 and the two support columns 120 are both arranged on the base 400. It can be understood that by arranging other components of the wetting device on the base 400, it is convenient for the tester to move the entire wetting device.

[0051] Furthermore, the infiltration device of this embodiment further includes a safety cover 500. The safety cover 500 is covered on the base 400, and both the mounting bracket 100 and the electrolyte tank 210 are located in the space enclosed by the safety cover 500 and the base 400. In this embodiment, a relatively enclosed space is jointly formed by the safety cover 500 and the base 400, so as to prevent the electrolyte in the electrolyte tank 210 from volatilizing to the outside and protect the personal safety of the test personnel.

[0052] Optionally, this embodiment further includes a controller 600. The controller 600 is located outside the safety cover 500 and is communicatively connected to the lifting mechanism 300, facilitating the test personnel to control the operation of the lifting mechanism 300 outside the safety cover 500. Exemplarily, the controller 600 can be communicatively connected to the lifting mechanism 300 through a communication cable. Corresponding through holes can be provided on the safety cover 500, and after the communication cable passes through the through holes, the through holes can be sealed with sealant, etc. A plurality of control buttons 610 can be provided on the controller 600. The plurality of control buttons 610 can include a start button, a rise button, a fall button, a stop button, etc. The test personnel can control the lifting mechanism 300 to perform corresponding operations by operating different control buttons 610.

[0053] The controller 600 of this embodiment further includes a timer 620. The plurality of control buttons 610 can also include a start button, a pause button, a zeroing button, etc. for controlling the timer 620. A scale 111 is provided on the fixing member 110. After the product is fixed to the fixing member 110, one end of the product can correspond to the zero point of the scale 111. In this embodiment, the electrolyte tank 210 is a transparent tank and the safety cover 500 is a transparent cover, facilitating the test personnel to observe the state of the product during the test.

[0054] Exemplarily, the infiltration device of this embodiment further includes a heating device. The heating device is arranged in the electrolyte tank 210 to heat the electrolyte, thereby accelerating the speed of the electrolyte infiltrating the product. Exemplarily, the heating device can be a heating film or a heating wire, etc. The heating device is communicatively connected to the controller 600, and the start and stop of the heating device can be controlled through the controller 600.

[0055] Before using the infiltration device of this embodiment, the product to be tested can be cut into a suitable shape first. For example, the product to be tested can be cut into a strip shape to fit the shape of the fixing member 110. The cutting size of the product to be tested can be set according to the size of the fixing member 110. For example, the length can be 60 - 100 mm and the width can be 20 - 40 mm.

[0056] Then the cut product to be tested can be bonded to the surface of the fixing member 110 provided with the scale 111, and the end of the product can be aligned with the zero point on the scale 111.

[0057] The following steps can be followed when using the infiltration device:

[0058] First, the length (ie, the dimension along the first direction X) and the height (ie, the dimension along the third direction Z) of the mounting rod 130 are adjusted according to the test requirements.

[0059] Secondly, the number of fixing members 110 to be used is determined, and the fixing members 110 with the products to be tested attached thereto are hung in the corresponding connecting grooves 131 .

[0060] Then, a certain amount of electrolyte is added to the electrolyte tank 210, and the volume of electrolyte added can be determined according to actual needs, and the tank cover 220 is covered. The containing structure 200 is moved to the lifting mechanism 300 under the mounting rod 130, so that each fixing member 110 is aligned with a through hole 221 on the tank cover 220.

[0061] Subsequently, the mounting bracket 100 and the containing structure 200 are covered with a safety cover 500 to prevent the electrolyte from volatilizing to the outside during the test. The control button 610 on the controller 600 controls the action of the lifting mechanism 300 to raise the electrolyte tank 210 to a suitable height so that the fixing member 110 and the product thereon are immersed in the electrolyte. When the product contacts the electrolyte, the control timer 620 starts timing.

[0062] Finally, after the preset time is reached, the timer 620 is controlled to stop timing, and the lifting mechanism 300 is controlled to move so that the electrolyte tank 210 is lowered to a suitable height, so that the fixture 110 and the product thereon are separated from the electrolyte tank 210. The diffusion length of the electrolyte on each product on the fixture 110 is read by the scale 111 on the fixture 110, and the value of the infiltration rate v can be calculated by the infiltration rate formula v=L / t (where L is the diffusion length of the electrolyte; t is the infiltration time of the electrolyte).

[0063] It is understandable that when the products on the multiple fixing members 110 are the same product, the electrolyte infiltration rate of the product can be further obtained by calculating the average value to improve the accuracy of the test.

[0064] When the products on the multiple fixing members 110 are different products, the electrolyte infiltration rates of the multiple products can be obtained at one time to shorten the test time.

[0065] In summary, the infiltration device of this embodiment makes the fixing member 110 contact with the electrolyte in the accommodating structure 200 by moving the mounting bracket 100 and / or the accommodating structure 200, so as to realize the test of the electrolyte infiltration rate of products such as diaphragms, positive electrode plates, and negative electrode plates. Since the opening of the electrolyte tank 210 is provided with a tank cover 220, the contact area between the electrolyte and the external environment is reduced. There are two lifting modes, manual and electric. The mounting rod 130 is extended, and the electrolyte tank 210 can test multiple samples, improving the accuracy, flexibility and efficiency of the electrolyte infiltration rate test.
