Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a battery testing device. Background Technology

[0002] When measuring the internal resistance of a battery, the test probe is typically crimped to the battery's tabs before testing.

[0003] In related technologies, cylinders or other driving components are typically used to move the test head in the vertical direction. Since the test head and the driving component are rigidly connected, and the positions of the tabs of different batteries in the vertical direction are not the same, it is easy for the pressure applied to the battery tabs when the test head moves downward to press them together to be too large or too small. Excessive pressure will cause the test head to damage the battery tabs, while insufficient pressure will cause poor contact between the test head and the battery tabs, affecting the test accuracy.

[0004] Therefore, battery testing devices in related technologies are prone to problems where the pressure between the test head and the battery tabs is too high or too low. Utility Model Content

[0005] To address the problem of excessive or insufficient pressure between the test head and the battery tabs in existing battery testing devices, this invention proposes a battery testing device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] The following is in conjunction with the appendix Figure 1-3 This invention describes a battery testing apparatus according to an embodiment of the present invention.

[0051] The battery testing device of this utility model embodiment includes a workbench 1, a placement platform 2, a testing platform 3, and a testing component 4.

[0052] like Figure 1-3 As shown, the placement platform 2 is located on the workbench 1. The placement platform 2 is used to place the battery. The battery has an identification code, which can be a QR code.

[0053] Optionally, multiple battery placement positions can be spaced out in the left-right direction on the placement platform 2, such as... Figure 1-3 As shown, two positions for placing batteries are arranged at intervals in the left and right directions on the placement platform 2.

[0054] The test platform 3 is arranged side by side with the placement platform 2 in the front-to-back direction. That is to say, the test platform 3 can be located in front of the placement platform 2 or behind the placement platform 2. At the same time, the battery tabs extend to the test platform 3. The test platform 3 is movable in the vertical direction so that the battery tabs can abut against the upper surface of the test platform 3.

[0055] It is understandable that the battery tabs may not be flush with the bottom surface of the battery. Therefore, the test platform 3, which is movable up and down, can support the battery tabs. In other words, the test platform 3 will move to a position where its upper surface is flush with the battery tabs.

[0056] like Figure 1-3 As shown, the detection component 4 is positioned above the test platform 3 in the vertical direction, and the detection component 4 is movable in the vertical direction.

[0057] The detection component 4 includes a base 401 and a test head 402 spaced apart in the vertical direction. The base 401 is located above the test head 402, and an elastic component 5 is provided between the base 401 and the test head 402.

[0058] The elastic component 5 includes a guide rod 501 and an elastic element 502. One end of the guide rod 501 is connected to the test head 402, and the other end of the guide rod 501 passes through the base 401 and is provided with a blocking element. The elastic element 502 is sleeved on the part of the guide rod 501 located between the base 401 and the test head 402.

[0059] The battery testing device of this utility model provides an elastic component 5 between the base 401 and the test head 402 of the detection component 4. On the one hand, the elastic component 5 can deform when the test head 402 contacts the battery electrode, buffering the pressure applied by the test head 402 to the battery electrode and preventing excessive pressure from damaging the battery electrode. On the other hand, after the detection component 4 reaches a preset position, the deformed elastic component 5 can apply pressure to the test head 402, making the contact between the test head 402 and the battery electrode tighter and avoiding poor contact problems.

[0060] Therefore, the battery testing device of this utility model embodiment does not have the problem of excessive or insufficient pressure between the test head 402 and the battery tab.

[0061] In some embodiments, the battery testing device of this utility model further includes a test drive component 6, which is disposed on the workbench 1. The drive end of the test drive component 6 is connected to the test bench 3 to drive the test bench 3 to move upward.

[0062] Optionally, the test drive unit 6 can be a cylinder, which is set on the workbench 1 and the drive end of the cylinder is connected to the test bench 3. In order to drive the test bench 3 to move more smoothly in the vertical direction, multiple cylinders can be set.

[0063] Furthermore, the battery testing device of this utility model embodiment also includes a testing bracket 7, which is disposed on the workbench 1. The testing bracket 7 is provided with a testing drive 403, and the driving end of the testing drive 403 is connected to the base 401 of the testing component 4 to drive the testing component 4 to move in the vertical direction.

[0064] Optionally, the detection drive 403 can be a cylinder, which is mounted on the detection bracket 7. The drive end of the cylinder is connected to the detection component 4. Specifically, the drive end of the cylinder is connected to the base 401 of the detection component 4. In order to drive the detection component 4 to move more smoothly in the vertical direction, multiple cylinders can be configured.

[0065] The battery testing device of this utility model embodiment can fix and support the testing drive component 403 by setting the testing bracket 7, which facilitates the movement of the testing drive component 403 in the vertical direction.

[0066] In some embodiments, the battery testing device of this utility model further includes a control module 13, which is connected to the test driver 6 and the detection driver 403 to control the test driver 6 and the detection driver 403.

[0067] The battery testing device of this utility model embodiment can control the movement of the test drive component 6 and the detection drive component 403 through the setting module. For example, the test drive component 6 can be controlled to move the test platform 3 in the vertical direction, and the detection drive component 403 can be controlled to move the detection component 4 in the vertical direction.

[0068] Furthermore, the battery testing device of this utility model embodiment also includes a barcode scanning component 8, which is disposed on the testing bracket 7. The barcode scanning component 8 is used to scan the identification code on the battery to collect battery information. The barcode scanning component 8 can be a barcode scanner, which is set towards the battery placed on the placement platform 2. Since the position of the battery on the placement platform 2 is relatively fixed, the barcode scanner can be set towards that position.

[0069] Meanwhile, the barcode scanning component 8 is connected to the control module 13 and transmits the battery information it collects to the control module 13. When the control module 13 receives the battery information collected by the barcode scanning component 8, the control module 13 controls the test drive component 6 and the detection drive component 403 to move. For example, the control module 6 controls the test platform 3 to move vertically until the upper surface of the test platform 3 is flush with the battery tabs. Then, the control module 13 controls the detection drive component 403 to move the detection component 4 downward, so that the test head 402 of the detection component 4 presses against the battery tabs to test the battery.

[0070] In some embodiments of the present invention, the battery testing apparatus further includes a shaping component 9, such as... Figure 1-3 As shown, the shaping assembly 9 includes a shaping roller 901, a first shaping drive 902, and a second shaping drive 903. The driving end of the first shaping drive 902 is connected to the shaping roller 901 to drive the shaping roller 901 to move in the vertical direction.

[0071] The driving end of the second shaping drive 903 is connected to the first shaping drive 902 to drive the first shaping drive 902 to move in the front-back direction.

[0072] Both the first shaping drive component 902 and the second shaping drive component 903 can be cylinders.

[0073] Furthermore, the shaping component 9 also includes a shaping connecting plate 904, which is connected to the driving end of the second shaping driving component 903;

[0074] There are two first shaping drive units 902, which are spaced apart in the left and right direction. The driving ends of the two first shaping drive units 902 are respectively connected to the two ends of the shaping roller 901.

[0075] The first shaping drive component 902 and the second shaping drive component 903 are connected to the control module 13. When the control module 13 receives the battery information collected by the barcode scanning component 8, it controls the test drive component 6 to move the test platform 3 vertically until the upper surface of the test platform 3 is flush with the battery tabs. The control device controls the second shaping drive component 903 to move the shaping roller 901 above the battery tabs on the test platform 3. The control device controls the first shaping drive component 902 to move downward to press the battery tabs on the test platform 3. The control device controls the second shaping drive 903 to drive the shaping roller 901 to roll and press the battery electrode in the front-back direction to shape the battery electrode. After the shaping is completed, the control device controls the first shaping drive 902 to drive the shaping roller 901 to move upward, and controls the second shaping drive 903 to drive the first shaping drive 902 and the shaping roller 901 to move backward. Then, the control device controls the detection drive 403 to drive the detection component 4 to move downward, so that the test head 402 of the detection component 4 presses against the battery electrode to test the battery.

[0076] In some embodiments, such as Figure 1-3 As shown, a fixing plate 10 is provided above the placement platform 2 in the vertical direction, and the fixing plate 10 is movable in the vertical direction.

[0077] To facilitate control of the fixed plate 10 moving in the vertical direction, the battery testing device of this utility model embodiment also includes a fixed drive component 11. The fixed drive component 11 is connected to the placement platform 2, and the drive end of the fixed drive component 11 is connected to the fixed plate 10 to drive the fixed plate 10 to move in the vertical direction. At the same time, the fixed drive component 11 can be connected to the control module 13 to control the fixed plate 10 to move in the vertical direction.

[0078] Specifically, when the control module 13 receives the battery information collected by the scanning component 8, the control module 13 controls the fixing drive component 11 to move the fixing plate 10 downward to press the battery, the control module 13 controls the test drive component 6 to move the test platform 3 vertically until the upper surface of the test platform 3 is flush with the battery tabs, the control device controls the second shaping drive component 903 to move the shaping roller 901 above the battery tabs on the test platform 3, and the control device controls the first shaping drive component 902 to move downward to press the test platform. On the battery tabs 3, the control device controls the second shaping drive 903 to drive the shaping roller 901 to roll and press the battery tabs in the front-back direction to shape the battery tabs. After the shaping is completed, the control device controls the first shaping drive 902 to drive the shaping roller 901 to move upward, and controls the second shaping drive 903 to drive the first shaping drive 902 and the shaping roller 901 to move backward. Then, the control device controls the detection drive 403 to drive the detection component 4 to move downward, so that the test head 402 of the detection component 4 presses against the battery tabs to test the battery.

[0079] Furthermore, such as Figure 1-3 As shown, there are two fixed drive components 11, which are spaced apart in the left and right direction. The drive ends of both fixed drive components 11 are connected to the fixed plate 10.

[0080] The battery testing device of this utility model embodiment, by setting two fixed driving members 11, can better control the fixed driving members 11 to drive the fixed plate 10 to move in the vertical direction.

[0081] In some embodiments, the battery testing device of this utility model further includes a temperature probe 12, which faces the battery disposed on the placement platform 2 and is connected to the control module 13.

[0082] Optionally, the temperature sensor 12 is an infrared temperature sensor.

[0083] The temperature sensor 12 can collect the battery temperature data during the battery test and transmit the temperature data to the control module 13.

[0084] This utility model embodiment also provides a battery testing method.

[0085] The battery testing method of this utility model embodiment is implemented based on the battery testing device described in the above embodiment.

[0086] The battery testing method of this utility model includes the following steps:

[0087] Step S100: Place the battery on the placement platform 2 and position the battery tabs toward the test platform 3;

[0088] Step S200: Control the test platform 3 to move upward so that the test platform 3 comes into contact with the battery's tabs;

[0089] Step S300: Control the detection component 4 to move downward, so that the detection head of the detection component 4 presses against the battery tab to test the battery. When the detection head presses against the battery tab, the elastic element 502 contracts.

[0090] Step S400: After the test is completed, control the detection component 4 to move upward so that the detection head of the detection component 4 is disengaged from the battery tab, and control the test platform 3 to move downward so that the test platform 3 is disengaged from the battery tab.

[0091] Step S500: Remove the battery from the placement platform 2.

[0092] The battery testing method of this utility model causes the elastic element 502 to contract when the test head presses against the battery tab. On the one hand, the elastic element 502 can deform when the test head 402 contacts the battery electrode, buffering the pressure applied by the test head 402 to the battery tab and preventing excessive pressure from damaging the battery tab. On the other hand, after the detection component 4 reaches the preset position, the deformed elastic component 502 can apply pressure to the test head 402, making the contact between the test head 402 and the battery tab tighter and avoiding poor contact problems.

[0093] Therefore, the battery testing method of this utility model embodiment does not have the problem of excessive or insufficient pressure between the test head 402 and the battery tab.

[0094] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
