[0002] As society places increasingly higher demands on the quality of lithium batteries, probes are being used more and more widely for testing their performance parameters. For example, in the manufacturing process of lithium batteries, it is necessary to perform formation and capacity testing on the individual cells of the battery module. Probes are used in this testing process; simply keeping the probes in working order allows for the testing of the individual cells.
[0003] When testing individual battery cells in a battery module, since there are many different types of battery modules, and different types of battery modules contain different battery cells, or the battery cells in different types of battery modules are arranged differently, the probes need to switch channels when testing different battery modules. For example, some probes can be retracted upwards to be in an avoidance state.
[0004] Currently, channel switching is performed manually by operating a probe. Therefore, there is a possibility of probe retraction errors, i.e., channel switching errors. This situation is not easy to detect, which will cause subsequent formation processes to fail. How to detect whether the probe channel has switched incorrectly is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0032] The detection tool provided by the embodiments of the present application will be described in detail below in conjunction with the drawings, specific examples and application scenarios.
[0033] As shown in Figures 1 to 6 The embodiments of the present application disclose a detection tool for detecting a probe assembly 600 of a device under test, where the device under test can be a formation device, and the probe assembly 600 includes a plurality of probes 610 arranged in a direction indicated by the x arrow line in the first horizontal direction Figure 1 And Figure 6 The probe 610 can be extended and retracted in the vertical direction, and the detection tool includes:
[0034] A bracket 100. The bracket 100 is used to form the overall appearance of the detection tool, and a receiving groove can be formed in the bracket 100, and the slot of the receiving groove can be upwardly arranged. The receiving groove is configured to accommodate components such as detection module 200, driving device 300, etc. Specifically, when the device under test is a formation device, the bracket 100 can be lifted by the press of the formation device, so that the detection module 200 below corresponds to the position of the probe assembly 600.
[0035] A detection module 200 is arranged in the bracket 100 and can move relative to the bracket 100 in the first horizontal direction, so that the detection module 200 can be moved to a position corresponding to each probe 610 respectively, so as to detect each probe 610.
[0036] The driving device 300 is arranged on the support 100 and connected with the detection module 200, so as to drive the detection module 200 to move along the first horizontal direction. The detection module 200 comprises the first sensor 210, which is configured to detect whether the detection end of each probe 610 is located at the first preset height during the movement along the first horizontal direction.
[0037] It should be noted that the first preset height herein can be the position of the detection end of the probe 610 when the probe 610 is extended downward to be in the working state (for example, the three probes 610 on the right side in FIG. 6B) or retracted upward to be in the avoiding state (for example, the leftmost probe 610 in FIG. 6B) when the probe 610 does not need to be in the working state. Figure 5 Figure 5 The detection end of the probe 610 is located at the second preset height which is higher than the first preset height. The probe 610 has the two states, i.e., the detection end of the probe 610 is located at the first preset height (working state) or the second preset height (avoiding state). Therefore, the detection of whether the detection end of the probe 610 is located at the first preset height can determine whether the probe 610 which needs to be in the working state is actually in the working state, and whether the probe 610 which needs to be in the avoiding state is actually in the avoiding state.
[0038] In the present application, the detection tool comprises the detection module 200 and the driving device 300. The detection module 200 comprises the first sensor 210, and the driving device 300 can drive the detection module 200 to move along the first horizontal direction, so that the first sensor 210 can correspond to the position of each probe 610 distributed along the first horizontal direction. When the first sensor 210 corresponds to each probe 610, the first sensor 210 can detect whether each probe 610 is located at the first preset height. If the first sensor 210 detects that the probe 610 which does not need to be located at the first preset height is located at the first preset height, or the probe 610 which needs to be located at the first preset height is not located at the first preset height, it can be determined that the channel switching error occurs.
[0039] In some embodiments, the detection module 200 can be located at the side of the probe assembly 600 and arranged towards the probe assembly 600, and the detection module 200 is located at the first preset height or the second preset height. Taking the case that the probe 610 is located at the first preset height as an example, the probe 610 located at the first preset height can be detected by the detection module 200, and the probe 610 located at the second preset height cannot be detected by the detection module 200; when the detection module 200 detects the probe 610, it can be determined that the detection module 200 is located at the first preset height, and when the detection module 200 does not detect the probe 610, it can be determined that the detection module 200 is located at the second preset height. Similarly, in the case that the probe 610 is located at the second preset height, when the detection module 200 detects the probe 610, it can be determined that the detection module 200 is located at the second preset height, and when the detection module 200 does not detect the probe 610, it can be determined that the detection module 200 is located at the first preset height.
[0040] In an alternative embodiment, the detection range of the first sensor 210 is configured such that the first preset height is located within the detection range and the second preset height is located outside the detection range, wherein the second preset height is higher than the first preset height, and the detection end can be telescoped between the first preset height and the second preset height.
[0041] The detection range of the detection module 200 used in this embodiment is small, the first preset height is located within the detection range, and the second preset height is located outside the detection range, that is, the detection end located at the first preset height is located within the detection range of the detection module and can be detected by the detection module, while the detection end located at the second preset height is located outside the detection range of the detection module and cannot be detected by the detection module, thereby detecting whether the detection end of each probe 610 is located at the first preset height.
[0042] It can be seen that the detection range of the detection module 200 of this embodiment is small, so the manufacturing cost of such detection module 200 is generally lower, and the installation and debugging are also easier; in addition, the detection module 200 with small detection range generally does not need very strong power, and its use cost is lower. Taking the photoelectric sensor as an example, the photoelectric sensor with limited detection distance generally does not need very strong light emission power, so the light emitting element of the photoelectric sensor consumes less electric energy.
[0043] In an alternative embodiment, the detection port of the first sensor 210 faces upward, so that the detection port faces the detection end. In this embodiment, the detection port of the detection module 200 faces upward, so that when the detection tool is used, the probe assembly 600 is located directly above the detection module 200, which can make the detection module 200 face the probe 610, and the direct installation can make the distance between the detection module 200 and the probe 610 shortest, so as to further reduce the detection range of the detection module 200, thereby further reducing the manufacturing cost and use cost. Of course, the detection port of the detection module 200 can also face obliquely upward, and the present application does not limit this.
[0044] Generally, the probe assembly 600 further comprises a needle plate 620, and each probe 610 is slidably connected to the needle plate 620 in the first horizontal direction, so as to adjust the distance between two adjacent probes 610 in the same probe assembly 600, thereby changing the arrangement position of the probe 610 to adapt to different types of battery monomers. However, the position of each probe 610 in the first horizontal direction is manually adjusted, so that the position adjustment error of the probe 610 can cause the channel switching error, and the error is not easy to be found.
[0045] In an alternative embodiment, the detection module 200 is further configured to detect whether each probe 610 is located at a preset position in the first horizontal direction during the movement in the first horizontal direction.
[0046] In this embodiment, the detection module 200 can also detect whether each probe 610 is located at a preset position in the first horizontal direction, that is, the detection module 200 can detect the probe 610 not located at the preset position, so as to find the channel switching error.
[0047] In an alternative embodiment, the detection module 200 can detect the distance between each probe 610 and the first reference point, which can be the maximum distance between the probe 610 and the first reference point, or the minimum distance, or the distance between the center of the probe 610 and the first reference point, so as to detect whether each probe 610 is located at a preset position in the first horizontal direction. For example, please refer to Figure 6 The first reference point can be located on the needle plate 620, for example, the inner edge of the aperture 622 on the needle plate 620, and the first reference point can also be located on other parts of the formation device, and the present application does not limit this.
[0048] If each probe 610 is located at the preset position in the first horizontal direction, the distance between each probe 610 and the first reference point is the theoretical distance. In actual detection, the detection module 200 detects the distance between each probe 610 and the first reference point as the detection distance. By comparing each theoretical distance and each detection distance, if each detection distance is within the error range of the corresponding theoretical distance, it indicates that each probe 610 is located at the preset position. If there is a detection distance that is outside the error range of the corresponding theoretical distance, it indicates that the probe 610 is not located at the preset position. As can be seen, the embodiment measures the distance between each probe 610 and the first reference point to detect whether each probe 610 is located at the preset position in the first horizontal direction, which can reduce error accumulation and thus ensure the accuracy of the measurement result.
[0049] In some embodiments, the detection module 200 can include only one sensor, which is used to detect whether the detection end of each probe 610 is located at the first preset height and whether each probe 610 is located at the preset position in the first horizontal direction. When using this embodiment for detection, in order to realize the above two functions, the detection module 200 constantly switches the detection mode in one single direction stroke, which increases the complexity of the control logic and reduces the detection efficiency.
[0050] In an alternative embodiment, the detection module 200 further includes a second sensor 220, and the first sensor 210 and the second sensor 220 are arranged in a spaced manner. For example, the first sensor 210 and the second sensor 220 can be distributed in a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The first sensor 210 and the second sensor 220 can both be reflective photoelectric sensors or reflective laser sensors.
[0051] The second sensor 220 is used to detect whether each probe 610 is located at the preset position in the first horizontal direction, that is, the above two functions are realized by the first sensor 210 and the second sensor 220 respectively.
[0052] In this embodiment, the detection module 200 includes the first sensor 210 and the second sensor 220. During the movement of the detection module 200 in the first horizontal direction, the first sensor 210 can detect whether the detection end of each probe 610 is located at the first preset height, and the second sensor 220 can detect whether each probe 610 is located at the preset position in the first horizontal direction. That is, the first sensor 210 and the second sensor 220 can realize their own functions in the same single direction stroke without frequently switching the detection mode as in the previous embodiment, thereby simplifying the control logic of the detection module 200 and improving the detection efficiency.
[0053] Generally, the number of probe assemblies 600 includes at least two, and thus it is required to detect whether each probe 610 of each probe assembly 600 is retracted correctly. In an alternative embodiment, the number of probe assemblies 600 includes at least two, and the at least two probe assemblies 600 are spaced apart along a second horizontal direction (indicated by the arrow line y) which is perpendicular to the first horizontal direction, and the driving device 300 is further capable of driving the detection module 200 to move along the second horizontal direction, that is, the detection module 200 is capable of moving along the second horizontal direction relative to the support 100, and the detection module 200 is further configured to detect the position of each probe assembly 600 during the movement along the second horizontal direction. Figure 1
[0054] For example, the detection module 200 can detect the position of each probe assembly 600 by detecting the position of a mark point on the needle plate 620 of each probe assembly 600, and the mark point can be a positioning pin hole 621. Figure 6
[0055] After the driving device 300 drives the detection module 200 to move along the first horizontal direction to detect whether the different probes 610 on the same probe assembly 600 are retracted correctly, the driving device 300 can be used to drive the detection module 200 to move along the second horizontal direction, and the detection module 200 can detect the position of other probe assemblies 600 during the movement along the second horizontal direction; for example, when the detection module 200 detects the position of the next probe assembly 600, the driving device 300 stops driving the detection module 200 to continue moving along the second horizontal direction, and then drives the detection module 200 to move along the first horizontal direction again to detect whether each probe 610 of the probe assembly 600 is retracted correctly.
[0056] In an alternative embodiment, the driving device 300 includes a first driving assembly 310 and a second driving assembly 320, the first driving assembly 310 includes a first driving mechanism, and the second driving assembly 320 includes a second driving mechanism and a crossbeam, the crossbeam extends along the second horizontal direction and is slidably connected with the support in the first horizontal direction, the detection module 200 is slidably connected with the crossbeam in the second horizontal direction, the second driving mechanism is arranged on the crossbeam and connected with the detection module 200 to drive the detection module 200 to slide along the second horizontal direction, and the first driving mechanism is connected with the crossbeam to drive the crossbeam to slide along the first horizontal direction.
[0057] Exemplarily, the first driving mechanism can include a first motor arranged on the support 100, a first screw rod 311 extending along a first horizontal direction, and a first pulley mechanism. The first screw rod 311 is rotationally coupled with the support 100 to be able to rotate about an axis thereof. The first motor is connected with the first screw rod 311 through the first pulley mechanism to drive the first screw rod 311 to rotate. The first screw rod 311 is threadedly coupled with the first cross beam. The second driving mechanism can include a second motor arranged on the cross beam, a second screw rod 321 rotationally coupled with the cross beam to be able to rotate about an axis thereof, and a second pulley mechanism 322. The second motor is connected with the second screw rod 321 through the second pulley mechanism 322 to drive the second screw rod 321 to rotate. The second screw rod 321 is threadedly coupled with the detection module 200.
[0058] In some embodiments, the detection module 200 can include only one sensor, which is used to detect whether the probe ends of the probes 610 are located at the first preset height and to detect the positions of the probe assemblies 600. In detection using this embodiment, in order to realize the above two functions, the detection module 200 needs to switch the detection mode to detect the positions of the probe assemblies 600 after detecting whether the probes 610 on one probe assembly 600 are retracted correctly, which increases the complexity of the control logic.
[0059] In an alternative embodiment, the detection module 200 further includes a third sensor 230, and the first sensor 210 and the third sensor 230 are arranged at intervals. The third sensor 230 is used to detect the positions of the probe assemblies 600. Exemplarily, the first sensor 210 and the third sensor 230 can both be reflective photoelectric sensors or reflective laser sensors.
[0060] In this embodiment, the detection module 200 includes the first sensor 210 and the third sensor 230, which respectively realize the above two functions. After detecting whether the different probes 610 on the same probe assembly 600 are retracted correctly using the first sensor 210, the detection mode of the first sensor 210 does not need to be switched. Instead, the positions of the different probe assemblies 600 can be directly detected using the third sensor 230, which can simplify the control logic of the detection module 200.
[0061] In an alternative embodiment, the detection tool further includes a conductive connector 400 arranged on the support 100. The detection module 200 and the driving device 300 are both electrically connected with the conductive connector 400. The conductive connector 400 is used to electrically contact with the power supply terminals of the device to be tested.
[0062] In the embodiment, the bracket 100 is further provided with a conductive connector 400. When the detection tool is connected to the testing device of the formation equipment, the conductive connector 400 is in electrical contact with the power supply terminal of the testing device. In this way, the testing device can be used to supply power to the detection tool. Therefore, it is not necessary to externally connect a power supply to the detection tool, thereby simplifying the structure of the detection tool. Of course, the conductive connector 400 of the detection tool can also be separately connected to an external power supply, thereby supplying power to the detection tool through the external power supply.
[0063] In an alternative embodiment, the detection tool can also interact with the controller of the testing device through the connection between the conductive connector 400 and the power supply terminal. The controller can control the components (such as the driving device 300 and the detection module 200) in the detection tool to operate, and obtain the information detected by the components, such as whether the detection end of the probe 610 is located at the first preset height, whether each probe 610 is located at the preset position in the first horizontal direction, and the position of each probe assembly 600. In this way, the detection tool does not need to be additionally provided with a controller, thereby further simplifying the structure of the detection tool.
[0064] In an alternative embodiment, please refer to Figure 3 The detection module 200 has a first limit position in the second horizontal direction. The detection tool further comprises a first position sensor 510, which is arranged on the bracket 100 and is electrically connected to the driving device 300. The first position sensor 510 can detect the detection module 200 located at the first limit position, and can control the driving state of the driving device 300, such as stopping the driving device 300, or controlling the driving device 300 to drive the detection module 200 to move in the opposite direction.
[0065] In the embodiment, when the detection module 200 moves to the first limit position, the first position sensor 510 can detect the detection module 200, and control the driving state of the driving device 300, so that the driving device 300 no longer drives the detection module 200 to further move in the direction close to the first limit position. Therefore, the detection module 200 is limited, and compared with the mechanical limiting, the detection module 200 does not collide mechanically, thereby reducing the risk of damage to the detection module 200.
[0066] And / or, the detection module 200 also has a second limit position in the second horizontal direction, and the detection tool further comprises a second position sensor 520, which is arranged on the support 100 and is electrically connected with the driving device 300. The second position sensor 520 can detect the detection module 200 located at the second limit position, and can control the driving state of the driving device 300, for example, control the driving device 300 to stop or control the driving device 300 to drive the detection module 200 to move in the opposite direction.
[0067] In the embodiment, when the detection module 200 moves to the second limit position, the second position sensor 520 can detect the detection module 200 and control the driving state of the driving device 300, so that the driving device 300 no longer drives the detection module 200 to further move in the direction close to the second limit position, thereby achieving the limiting of the detection module 200. Compared with the mechanical limiting, the limiting method of the embodiment can reduce the risk of damage to the detection module 200 due to mechanical collision.
[0068] The application further discloses a detection tool for detecting probe assemblies 600 of a device to be tested. The number of probe assemblies 600 includes at least two, and the at least two probe assemblies 600 are distributed along a second horizontal direction. The probe assembly 600 comprises a plurality of probes 610 arranged along a first horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. The detection tool comprises a support 100, a detection module 200 and a driving device 300. The detection module 200 is arranged on the support 100 and can move relative to the support 100. The driving device 300 is arranged on the support 100 and connected with the detection module 200, so as to drive the detection module 200 to move along the first horizontal direction or the second horizontal direction.
[0069] The detection module comprises a first sensor 210, a second sensor 220 and a third sensor 230. The first sensor 210 is configured to detect whether the detection end of each probe 610 is located at a first preset height during movement along the first horizontal direction. The second sensor 220 is configured to detect whether each probe 610 is located at a preset position in the first horizontal direction. The third sensor 230 is configured to detect the position of each probe assembly 600.
[0070] The first sensor 210 of the present application can detect whether the probe end of each probe 610 is located at a first preset height, the second sensor 220 can detect whether each probe 610 is located at a preset position in a first horizontal direction; the third sensor 230 can detect the position of each probe assembly 600. Moreover, the first sensor 210, the second sensor 220 and the third sensor 230 are three independent sensors, each sensor does not need to frequently switch the detection mode, thereby simplifying the control logic of the detection module 200 and improving the detection efficiency.
[0071] The above embodiments of the present application mainly describe the differences between various embodiments, and the different optimization features between various embodiments can be combined to form a better embodiment as long as they are not contradictory. In view of the brevity of the writing, it will not be repeated here. The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the above specific embodiments, the above specific embodiments are only illustrative and not restrictive, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the protection scope of the claims.
