[0025] In order to solve the problem of inconvenient observation of the pole piece in the prior art, the present application provides a pole piece positioning device.
[0026] As Figure 1 and Figure 2As shown, the pole piece positioning device in the application includes a fixed seat 10, a first positioning member 20, and a second positioning member 30. The first positioning member 20 and the second positioning member 30 are both multiple, and the first positioning member 20 and the second positioning member 30 are both arranged on the top surface of the fixed seat 10. At least one first positioning member 20 in the plurality of first positioning members 20 and at least one second positioning member 30 in the plurality of second positioning members 30 are oppositely arranged on a pair of opposite edges of the top surface of the fixed seat 10, and the first positioning member 20 is detachably arranged on the fixed seat 10, and the second positioning member 30 is fixedly arranged on the fixed seat 10.
[0027] When using the pole piece positioning device in the application, the pole piece 40 to be observed can be placed on the top surface of the fixed seat 10. At the same time, since the pole piece positioning device also has a plurality of first positioning members 20 and a plurality of second positioning members 30 to fix different pole pieces 40, it is ensured that the pole piece 40 will not shake during the observation process of the pole piece 40. At the same time, since at least one first positioning member 20 in the plurality of first positioning members 20 and at least one second positioning member 30 in the plurality of second positioning members 30 are oppositely arranged on a pair of opposite edges of the top surface of the fixed seat 10, the first positioning member 20 and the second positioning member 30 arranged on a pair of opposite edges of the top surface of the fixed seat 10 can be used to position both ends of the same pole piece 40, thereby ensuring that the first positioning member 20 and the second positioning member 30 will not interfere with the observation of the pole piece 40 during the positioning process of the pole piece 40. Therefore, the pole piece positioning device in the application effectively solves the problem of inconvenient observation of the pole piece in the prior art.
[0028] It should be noted that the pole piece positioning device in the application can accurately fix the pole piece during observation, avoid affecting the observation results due to the movement of the pole piece, and improve the accuracy and efficiency of observation. In actual application, this design can significantly reduce observation errors, especially in cases where long-term observation or comparative observation is required, the stable position of the pole piece can be maintained, and the inconvenience caused by repeated positioning is avoided. For example, in the quality control link of battery production, the positioning device can be used to quickly and accurately position the pole piece for accurate size and structure inspection, effectively improving the pass rate of products.
[0029] In one specific embodiment of the application, one side of the top surface of the fixed seat 10 is provided with a plurality of first positioning members 20, and the other side is provided with a plurality of second positioning members 30.
[0030] Specifically, the number of the first positioning members 20 and the number of the second positioning members 30 are equal and one-to-one corresponding. That is to say, in the plurality of first positioning members 20 and the plurality of second positioning members 30 of the present application, the corresponding first positioning member 20 and the second positioning member 30 form a group, so that the plurality of first positioning members 20 and the plurality of second positioning members 30 can be divided into a plurality of groups, and the first positioning member 20 and the second positioning member 30 of the same group respectively position the two ends of the same pole piece, so that the plurality of first positioning members 20 and the plurality of second positioning members 30 can correspond to a plurality of pole pieces, thereby ensuring that the pole piece positioning device in the present application can simultaneously position a plurality of pole pieces to improve the observation efficiency of a plurality of pole pieces.
[0031] Optionally, the connecting line of the corresponding first positioning member 20 and the second positioning member 30 is perpendicular to the side edge of the fixed seat 10 where the first positioning member 20 is located and the side edge of the fixed seat 10 where the second positioning member 30 is located.
[0032] Optionally, all the first positioning members 20 are arranged on the same side edge of the top surface of the fixed seat 10, and all the second positioning members 30 are arranged on the same side edge of the top surface of the fixed seat 10.
[0033] That is to say, when the top surface of the fixed seat 10 is rectangular, one set of relatively parallel side edges of the rectangle respectively arrange the first positioning member 20 and the second positioning member 30, and the other set of relatively parallel side edges are parallel to the connecting line of the first positioning member 20 and the second positioning member 30 of the same group. Of course, in the present application, the arrangement position of the first positioning member 20 and the second positioning member 30 can also be adaptively adjusted according to the actual design situation.
[0034] Specifically, the plurality of first positioning members 20 and the plurality of second positioning members 30 are arranged at equal intervals on the fixed seat 10. By such arrangement, when a plurality of pole pieces are simultaneously positioned using the pole piece positioning device in the present application, it can be ensured that adjacent pole pieces will not interfere with each other.
[0035] Preferably, the distance between the two adjacent first positioning members 20 and the distance between the two adjacent second positioning members 30 are both greater than or equal to 20mm.
[0036] In one specific embodiment of the present application, the overall size of the fixed seat 10 is 200mm*80mm*10mm. The length is designed to be 200mm, the width is designed to be 80mm, which meets the test of 18650 cylindrical battery (the positive pole piece is about 58mm wide), also meets the test of 21700 cylindrical battery (the positive pole piece is about 63mm wide), and also meets the test of part of the negative pole piece; the thickness is designed to be 10mm, which is convenient for the installation or processing of the first positioning member 20 and the second positioning member 30.
[0037] In one specific embodiment of the present application, the first positioning member 20 is a nut. The second positioning member 30 is a buckle, and the buckle has a clamping opening. This design makes the fixing of the pole piece firm and convenient. The nut can provide sufficient fixing force, and the buckle facilitates the quick installation and disassembly of the pole piece, which is suitable for laboratory environments that require frequent replacement of the pole piece. In actual operation, the combination of the nut and the buckle can achieve stable fixing and convenient replacement of the pole piece, improving the efficiency and flexibility of pole piece observation. Of course, the first positioning member 20 and the second positioning member 30 can also be selected in other structures in the present application.
[0038] Optionally, at least one mounting groove 11 is arranged on a pair of opposite sides of the top surface of the fixing seat 10 corresponding to the first positioning member 20 and the second positioning member 30, and the clamping opening faces the groove bottom of the mounting groove 11. This structure design makes the buckle more closely fixed on the fixing seat 10, avoiding the loosening of the buckle during observation, and improving the stability of the pole piece positioning. Moreover, through such arrangement, the pole piece can be conveniently installed and disassembled.
[0039] Optionally, the height of the clamping opening is higher than or flush with the top surface of the fixing seat 10. Through such arrangement, the fit between the pole piece and the top surface of the fixing seat 10 can be ensured, thereby preventing the pole piece from colliding with the lens during observation.
[0040] Optionally, at least the top surface of the fixing seat 10 is provided with a detection coating, and the color of the detection coating is black. Through such arrangement, the contrast can be effectively improved during the observation of the pole piece. In one specific embodiment of the present application, the entire fixing seat 10 is black.

[0042] 1. The problem of inconvenient observation of the pole piece by the microscope in the prior art is effectively solved;
[0043] 2. The structure is simple, and the performance is stable.
