In the related art, the probe device is provided with a current probe and a voltage probe, and the relative positions of the current probe and the voltage probe are fixed, resulting in poor test results.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components.

[0037] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] See also Figures 1 to 2 The present application provides a cell probe detection device 20 for cooperating with a cell wire detection device 10 to perform electrical performance testing on a cell. The cell probe detection device 20 provided in the present application includes a support frame 21, a plurality of current test probes 22, and a plurality of voltage test probes 23. The plurality of current test probes 22 are fixedly arranged on the support frame 21, and the plurality of voltage test probes 23 are located on one side of the plurality of current test probes 22. The plurality of voltage test probes 23 are movably arranged on the support frame 21 along a direction perpendicular to the arrangement direction of the plurality of current test probes 22 to adjust the spacing between the voltage test probes 23 and the current test probes 22.

[0039] A plurality of current test probes 22 are arranged on the support frame 21. In the arrangement direction of the plurality of current test probes 22, a voltage test probe 23 is provided for every plurality of current test probes 22. The specific number of the plurality of current test probes 22 and the plurality of voltage test probes 23 is not limited in this embodiment of the application.

[0040] The present embodiment does not limit the specific implementation of the multiple voltage test probes 23 being movably disposed on the support frame 21. By movably disposing the multiple voltage test probes 23 on the support frame 21 in a direction perpendicular to the arrangement of the multiple current test probes 22, the cell probe detection device 20 can adjust the distance between the voltage test probes 23 and the current test probes 22, thereby achieving optimal testing results for the cell testing device 100. Furthermore, the distance between the voltage test probes 23 and the current test probes 22 can be adjusted individually according to different testing requirements, thereby ensuring maximum adjustability.

[0041] It should be noted that, during the electrical performance test of a cell, different distances between the voltage test probes 23 and the current test probes 22 in the cell probe detection device 20 can easily lead to different electrical performance test results for the cell. Therefore, by making the distance between the voltage test probes 23 and the current test probes 22 in the cell probe detection device 20 adjustable, the cell testing apparatus 100 can ensure better testing results. The distance between the voltage test probes 23 and the current test probes 22 refers to the distance perpendicular to the arrangement direction of the current test probes 22.

[0042] Please also refer to Figures 3 and 4 In some embodiments, the voltage test probe 23 can be movably mounted on the support frame 21 via a mounting block 24. The support frame 21 is provided with a plurality of mounting blocks 24, each corresponding to a voltage test probe 23. Each mounting block 24 is provided with a receiving groove 241, so that the voltage test probe 23 can be movably mounted in the receiving groove 241.

[0043] The embodiment of the present application does not limit the specific structure of the mounting block 24. The receiving groove 241 on the mounting block 24 can be a through groove. After the voltage test probe 23 is movably set in the receiving groove 241, the upper and lower ends of the voltage test probe 23 extend out of the receiving groove 241. Figure 4 As shown, for example, the accommodating groove 241 can be a rectangular through groove with rounded corners at both ends. Correspondingly, the mounting block 24 is a sleeve structure corresponding to the shape of the accommodating groove 241, but the shape of the mounting block 24 is not limited thereto.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, to ensure the stability of the voltage test probe 23 as it moves within the accommodating groove 241, the sidewalls of the accommodating groove 241 are further provided with a slide groove 242. Correspondingly, the voltage test probe 23 is provided with a slider 25 that cooperates with the slide groove 242. Thus, when the voltage test probe 23 moves along the accommodating groove 241, the slider 25 on the voltage test probe 23 moves along the slide groove 242, thereby ensuring the stability of the movement of the voltage test probe 23 and preventing the voltage test probe 23 from rotating during movement. In some embodiments, the sidewalls of the accommodating groove 241 can be provided with at least two slide grooves 242, and the at least two slide grooves 242 are arranged perpendicular to the extension direction of the slide groove 242. It is understood that the number and position of the sliders 25 provided on the voltage test probe 23 correspond to the slide grooves 242. For example, if two slide grooves 242 are provided on the sidewall of the accommodating groove 241, two sliders 25 are provided on the voltage test probe 23 accordingly. The two slide grooves 242 are arranged perpendicular to the extension direction of the slide grooves 242, and the corresponding two sliders 25 are arranged along the length of the voltage test probe 23. Since the voltage test probe 23 has a certain length, the provision of at least two slide grooves 242 on the sidewall of the accommodating groove 241 further ensures the stability of the movement of the voltage test probe 23.

[0045] After the voltage test probe 23 is moved to the specified position, in order to keep the relative positions of the voltage test probe 23 and the current test probe 22 stable during the test, in some embodiments, the cell probe detection device 20 may further include a locking member 26. The locking member 26 is threadedly connected to the slider 25 and is located on the side of the mounting block 24 facing away from the accommodating groove 241. The locking member 26 is used to prevent the slider 25 from moving along the slide groove 242 by tightly abutting against the mounting block 24, thereby preventing the voltage test probe 23 from moving along the accommodating groove 241. For example, one of the locking member 26 and the slider 25 may be provided with a threaded column, and the other may be provided with a threaded hole, and the locking member 26 is threadedly engaged with the slider 25, and the end face of the locking member 26 is tightly abutted against the side of the mounting block 24 facing away from the accommodating groove 241.

[0046] like Figure 5As shown, in some embodiments, an adjusting screw 27 is rotatably provided on the mounting block 24, and a slider 25 that is threadably engaged with the adjusting screw 27 is provided on the voltage test probe 23. In this way, the adjusting screw 27 can be rotated to allow the slider 25 to drive the voltage test probe 23 to move along the accommodating groove 241, and at the same time, the threaded engagement between the adjusting screw 27 and the slider 25 can be utilized to prevent the voltage test probe 23 from freely moving in the accommodating groove 241. In addition, the distance between the voltage test probe 23 and the current test probe 22 is adjusted by adjusting the mechanism of threaded engagement between the screw 27 and the slider 25, which converts the rotation of the adjusting screw 27 into the movement of the voltage test probe 23, thereby achieving the accuracy of fine distance adjustment. Among them, the slider 25 is threadedly engaged with the adjusting screw 27, and it can be understood that the slider 25 is provided with a threaded hole that is engaged with the adjusting screw 27, such as Figure 5 As shown, one end of the slider 25 can be slidably engaged with the slide groove 242 , and a threaded hole is provided on the side of the other end of the slider 25 opposite thereto.

[0047] It should be noted that, in the process of adjusting the voltage test probe 23 in the direction perpendicular to the arrangement of the current test probes 22, the battery cell probe detection device 20 provided in the above embodiment of the present application may be to adjust the voltage test probe 23 to a position in the same row as the current test probe 22, such as Figure 1 and Figure 2 As shown, at this time, the voltage test probe 23 can be directly adjusted to a position in the same row as the current test probe 22 in the receiving groove 241 of the mounting block 24, or a probe mounting hole can be provided at a corresponding position on the support frame 21, and the voltage test probe 23 can be provided in the probe mounting hole to be in the same row as the current test probe 22.

[0048] like Figure 6 As shown, in some embodiments, the present application further provides a cell testing device 100, which includes a cell wire detection device 10 and a cell probe detection device 20 according to any of the above embodiments. Each cell probe detection device 20 in the cell testing device 100 corresponds to a cell wire detection device 10. The wire assembly in the cell wire detection device 100 is arranged opposite to the current test probe 22 and the voltage test probe 23 in the cell probe detection device 20.

[0049] The cell wire detection device 10 and the cell probe detection device 20 in the cell testing device 100 cooperate with each other to complete the electrical performance test of the cell. It can be understood that the cell testing device 100 also includes a cell supporting device 30, such as Figure 6As shown, the cell support device 30 includes a rotating base 31 and a plurality of cell brackets 32 arranged around the rotating base 31. For example, the number of cell brackets 32 around the rotating base 31 can be two or four, but is not limited thereto. In the embodiment of the present application, four cell brackets 32 are arranged around the rotating base 31 as an example. Correspondingly, the cell wire detection device 10 is arranged above one of the cell brackets 32, and the cell probe detection device 20 is arranged below the corresponding cell bracket 32. The cell wire detection device 10 and the cell probe detection device 20 constitute the electrical performance test position of the battery bias film. The rotating base 31 drives the cells on each cell bracket 32 ​​to pass through the electrical performance test position in turn for testing by rotating. The implementation of the present application does not limit the specific structure of the cell probe detection device 20. The cell probe detection device 20 is generally provided with a battery test probe and a voltage test probe 23, so as to cooperate with the cell wire detection device 10 to complete the electrical performance test of the cell.

[0050] like Figure 7 and Figure 8 As shown, in some embodiments, a cell wire detection device 10 includes a carrier board 11 and a wire assembly. The wire assembly includes a plurality of wire structures 12, which are arranged and distributed on one side of the carrier board 11. The wire structures 12 are used to cooperate with a current test probe 22 or a voltage test probe 23 to perform electrical testing. The wire structures 12 include wires 13 and a flexible mounting bar 14. The length of the flexible mounting bar 14 corresponds to the length of the wires 13. The wires 13 are embedded in the flexible mounting bar 14 along the length of the flexible mounting bar 14. At the same time, the side of the flexible mounting bar 14 facing away from the wires is fixed to the carrier board 11.

[0051] The carrier plate 11 in the cell wire detection device 10 is a transparent glass plate, but is not limited thereto. In the embodiments of this application, a transparent glass plate is used as an example for description. The cell wire detection device 10 may also include a mounting frame, on which the carrier plate 11 is mounted.

[0052] The plurality of wire structures 12 in the cell wire detection device 10 are arranged and distributed on one side surface of the carrier 11. It can be understood that the plurality of wire structures 12 are arranged in a direction perpendicular to the length of the wire 13. Since adjacent wires 13 in the cell wire detection device 10 are generally spaced a certain distance apart, the diameter of the wire 13 is generally 0.3mm, and the wire 13 is embedded in the flexible mounting strip 14. It can be understood that the width of the flexible mounting strip 14 is slightly larger than the diameter of the wire 13. In this way, the plurality of wire structures 12 on the carrier 11 will also be spaced a certain distance apart. Compared with covering the carrier 11 with a whole film, the obstruction of the wire 13 is effectively reduced. For example, for an 182mm battery, a 0.3mm wire attached to the flexible mounting strip 14 only occupies less than 6%; and for a 210mm battery, it only occupies less than 5%. Compared with conventional double-row probes or silver bars with a width of not less than 3 mm, taking an 182 mm battery as an example, it will occupy not less than 39%. It can be seen that the battery cell wire detection device 10 provided in this application effectively reduces the occlusion ratio of the wire 13.

[0053] Wire structure 12 includes wires 13 and flexible mounting strips 14. Wires 13 are conductive metal wires, such as, but not limited to, silver or copper. Flexible mounting strips 14 have a certain degree of flexibility. For example, in some embodiments, flexible mounting strips 14 may be made of, but not limited to, EVA or PVB.

[0054] The length of the flexible mounting bar 14 corresponds to the length of the wire 13, which can be understood as the length of the flexible mounting bar 14 being the same as the length of the wire 13, so that the entire wire 13 can be embedded in the flexible mounting bar 14. The wire 13 is embedded in the flexible mounting bar 14 along the length direction of the flexible mounting bar 14, that is, the central axis of the wire 13 in the wire structure 12 is arranged parallel to the central axis of the flexible mounting bar 14. The cross-sectional shape of the wire 13 is generally circular. The present application does not limit the cross-sectional shape of the flexible mounting bar 14. For example, the flexible mounting bar 14 can be a long strip structure with a rectangular, trapezoidal or regular hexagonal cross-sectional shape, but is not limited to this. In the embodiment of the present application, the flexible mounting bar 14 is taken as an example of a long strip structure with a rectangular cross-sectional shape. The wire 13 is embedded in one side surface of the flexible mounting bar 14, and the side of the flexible mounting bar 14 facing away from the wire 13 is fixed to the carrier 11. It should be noted that when the cell wire detection device 10 is in use, the wire 13 needs to be in contact with the cell. It is understandable that after the wire 13 is embedded in one side of the flexible mounting bar 14, the wire 13 needs to protrude from the surface of the flexible mounting bar 14. In some embodiments, in the radial direction along the cross section of the wire 13, the portion of the wire 13 embedded in the flexible mounting bar 14 can account for 1 / 3-2 / 3 of the wire, for example, it can be 1 / 3, 1 / 2 or 2 / 3, but is not limited thereto. For example, when the portion of the wire 13 embedded in the flexible mounting bar 14 is 1 / 2, that is, half of the cross section of the wire 13 is embedded in the flexible mounting bar 14, this can ensure the stability of the wire 13 installed in the flexible mounting bar 14 and ensure that the wire 13 can fully contact the cell.

[0055] The wire 13 is embedded in the flexible mounting strip 14. In some embodiments, the wire 13 can be melt-embedded in the flexible mounting strip 14. For example, the flexible mounting strip 14 is heated to melt so that the wire 13 can be embedded in a side surface of the flexible mounting strip 14. In some embodiments, the wire 13 can be melt-embedded in the flexible mounting strip 14 by lamination and heating.

[0056] It should be noted that if Figure 7 As shown, among the plurality of wire structures 12, a portion of the wire structures 12 is generally constructed as a first wire structure 12a, and another portion of the wire structure 12 is constructed as a second wire structure 12b. In some embodiments, the plurality of first wire structures 12a on the carrier 11 are evenly spaced and distributed on the carrier 11. The number of second wire structures 12b set in the plurality of wire structures 12 is less than the number of first wire structures 12a. The embodiment of the present application is described by taking the example of setting one second wire structure 12b for every two first wire structures 12a. At the same time, the second wire structure 12b can be set between two adjacent first wire structures 12a, and the second wire structure 12b can be set close to one of the two adjacent first wire structures 12a, but it is not limited to this.

[0057] In addition, if Figure 9 As shown, since the second wire structure 12b and the first wire structure 12a need to be insulated, an insulating spacer 15 can be provided between the second wire structure 12b and the first wire structure 12a. The insulating spacer 15 is made of insulating material such as rubber or plastic.

[0058] The cell testing device 100 provided in the present application adopts all the technical solutions of all the embodiments of the above-mentioned cell probe detection device 20, and therefore has at least all the beneficial effects brought about by the technical solutions of the embodiments of the above-mentioned cell probe detection device 20, which will not be repeated here. In addition, when the cell wire detection device 10 in the cell testing device 100 provided in the present application is fixedly mounted on the carrier 11 through the flexible mounting strip 14, the wire can be bent accordingly according to the shape of the contact, so that it can fit tightly and ensure the test effect. At the same time, when the cell wire detection device 10 and the cell probe detection device 20 detect the cell, the two sides of the cell are equivalent to soft contact with the wire 13 and hard contact with the probe, which effectively reduces the fragmentation rate of the cell compared to hard contact on both sides of the cell. Moreover, each of the plurality of wires 13 is arranged on the carrier 11 in the form of a wire structure 12, and each wire corresponds to a flexible mounting strip 14, which is equivalent to distributing the flexible mounting strips 14 only at the positions where the wires are distributed on the carrier 11. There is no obstructed light-transmitting area between adjacent wire structures 12, which effectively maximizes the minimum obstruction of the wires 13.

[0059] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
