[0002] The modules are assembled from individual battery cells in series and parallel to form larger capacity cell modules, and then these cell modules are further assembled into PACKs (battery packs) in series and parallel. As a core component of the energy storage industry, the safety of the PACK is particularly important. One crucial indicator affecting its safety performance is the insulation withstand voltage performance of the cell modules. Therefore, OCV (open circuit voltage) and insulation tests are required for the cell modules, and currently, these tests are conducted manually.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] To address the technical problem that manual inspection in existing technologies carries a high risk of operational errors, resulting in low inspection efficiency for battery cell modules, this application provides a battery cell module testing mechanism that improves the testing flexibility and compatibility of the mechanism, as well as the inspection efficiency for battery cell modules.

[0076] OCV stands for open circuit voltage.

[0077] like Figures 1-6As shown, the battery cell module testing mechanism disclosed in this utility model includes a barcode scanning component 100, a switching device, an OCV testing component 200, a first insulation testing component 300, a second insulation testing component 400, and a base 500. The barcode scanning component 100 includes a universal joint and a barcode scanner. The universal joint is connected to the base 500 and is used to drive the barcode scanner to rotate. The barcode scanner is used to identify the module information of the battery cell module 502. The switching device includes a first moving component 600, a second moving component 700, and an adjusting plate 503. There are two first moving components 600, which are arranged opposite each other on the first and second sides of the base 500. The adjusting plate 503 is mounted above the battery cell module 502, and its two... The first moving component 700 is connected to two first moving components 600 respectively. The second moving component 700 is connected to the adjustment plate 503 and can move between the two first moving components 600 along the adjustment plate 503. The OCV test component 200 and the first insulation test component 300 are connected to the second moving component 700. The OCV test component 200 is used to detect the open circuit voltage of the cell module 502. The first insulation test component 300 is used to connect the total positive and total negative terminals of the cell module 502. The second insulation test component 400 is arranged at the first end of the base 500 and is used to connect the end plate of the cell module 502. There are two type-changing devices, which are arranged opposite to each other at the first and second ends of the base 500.

[0078] Specifically, a tooling plate 501 is arranged at the bottom of the cell module 502. The tooling plate 501 has module information that can be scanned by a barcode scanner. The module information includes the number of cells that make up the module, whether the cell module 502 is a type A module or a type B module (the total positive electrode and the total negative electrode are distributed at both ends of the cell module 502, but their distribution may be left and right, thus forming an AB module), and other parameters that can identify the cell module 502. Through the above module information, on the one hand, it can be determined that the first moving component 600 drives the adjusting plate 503 to move to the preset position so that the two ends of the cell module 502 correspond to the two changing devices respectively. On the other hand, it can be determined that the two second moving components 700 are respectively on the two adjusting plates 503, so that the OCV test component 200 and the first insulation test component 300 on the second moving component 700 can be connected to the cell module 502 at the preset position. That is, by scanning the code to determine the module information, the cell module testing mechanism can adjust itself and automatically switch the test type to facilitate OCV test and insulation test of cell module 502.

[0079] Specifically, a track for transporting the cell module 502 is arranged in the middle of the base 500. In use, the cell module 502 moves along the track between two changing devices. The changing device adjusts its position through the first moving component 600 to adapt to both ends of the cell module 502. The barcode scanner scans the tooling plate 501 to obtain module information. The second moving component 700 adjusts its position so that the OCV test component 200 and the first insulation test component 300 can connect the cell module 502 in a preset position.

[0080] The battery cell module testing mechanism provided by this utility model, when in use, uses a barcode scanner to scan the module information of the battery cell module 502. The switching device moves the first moving component 600 according to the module information, and the second moving component 700 moves on the adjusting plate 503. When the first insulation testing component 300 is in a preset position and the second insulation testing component 400 is connected to the end plate of the battery cell module 502, the insulation value of the total positive and total negative terminals of the battery cell module 502 to the end plate can be detected. When the OCV testing component 200 is in a preset position, the open circuit voltage of the battery cell module 502 can be detected. The positive and negative terminals of the cell module 502 are located at both ends of the cell module 502. During OCV testing, the two OCV test components 200 are connected to the positive and negative terminals simultaneously, respectively. During insulation testing, one first moving component 600 is connected to the positive terminal and the second insulation test component 400 is connected to the end plate of the cell module 502, or another first moving component 600 is connected to the negative terminal and the second insulation test component 400 is connected to the end plate of the cell module 502.

[0081] By setting up a conversion device that is arranged opposite to both ends of the base 500, the positive and negative terminals and the end plate of the cell module 502 can be flexibly connected, enabling the cell module testing mechanism to test cell modules 502 with different module information, thereby improving the testing flexibility and compatibility of the cell module testing mechanism, as well as the testing efficiency of the cell module 502.

[0082] To optimize the above technical solution, the first moving component 600 includes a first driver 601, a first slide rail, and a first connecting plate. The first driver 601 is connected to the first connecting plate and drives the first connecting plate to move. The first connecting plate is connected to the end of the adjusting plate 503 and drives the end of the adjusting plate 503 to move along the first slide rail. Specifically, a support column is arranged at the bottom of the first driver 601, and the support column is fixedly connected to the base 500. The height of the support column should be greater than the height of the cell module 502 so that the adjusting plate 503 can be mounted above the cell module 502, allowing the OCV testing component 200 and the first insulation testing component 300 to connect to the cell module 502 at a preset position. Specifically, the first driver 601 can be a servo motor, which is connected to the first connecting plate through a transmission device and drives the first connecting plate to move linearly. The first driver 601 can also be a drive cylinder. Specifically, the first connecting plate can be the slider itself on the first slide rail, or a plate connected to the slider on the first slide rail. It should be noted that at least one of the two relatively arranged first moving components 600 can have the above structure, and the other of the two first moving components 600 can only be arranged with a slide rail and a slider, and the end of the adjusting plate 503 is connected to the slider. When the first driver 601 drives one end of the adjusting plate 503 to move, the other end of the adjusting plate 503 moves accordingly.

[0083] The function of the first moving component 600 is to switch the positions of the OCV test component 200 and the first insulation test component 300. When an OCV test or insulation test is required, the adjusting plate 503 is moved to change its relative position along the length of the cell module 502, so that the OCV test component 200 or the first insulation test component 300 can correspond to the area to be connected in the cell module 502. Therefore, the first moving component 600 is compatible with cell modules 502 of different lengths, and moving parameters can be set for cell modules 502 of different lengths, so that the OCV test component 200 and the first insulation test component 300 can move to the corresponding positions for testing. This arrangement allows the cell module testing mechanism to be used to test cell modules 502 of different lengths, thereby improving the testing flexibility and compatibility of the cell module testing mechanism, as well as the testing efficiency of the cell module 502.

[0084] To optimize the above technical solution, the second moving component 700 includes a second driver 701, a second connecting plate 702, and a third connecting plate 703. The adjusting plate 503 has a second slide rail. The second connecting plate 702 connects the second slide rail to the second driver 701. The third connecting plate 703 connects the second driver 701 to the OCV test component 200 and the first insulation test component 300. The second driver 701 drives the OCV test component 200 and the first insulation test component 300 to move linearly. Specifically, the second driver 701 is preferably a slide cylinder. Specifically, the adjusting plate 503 has a second slide rail, and the second connecting plate 702 is equivalent to a slider on the second slide rail, connecting the second driver 701 to the adjusting plate 503, allowing the second driver 701 to move on the adjusting plate 503. Specifically, the adjustment plate 503 has multiple positioning holes. When the left and right positions of the input cell module 502 change, the operator can adjust the relative position of the second driver 701 on the adjustment plate 503 according to the needs of use, so as to achieve long-distance movement in the width direction of the cell module 502, thereby achieving compatibility with the cell module 502. Specifically, the total positive or total negative terminal of the cell module 502 may appear on the left or right side of the same end of the cell module 502. When the cell module 502 needs to be tested, the second driver 701 drives the OCV test component 200 and the first insulation test component 300 to move in a straight line, so as to achieve precise control of the relative position of the OCV test component 200 and the first insulation test component 300 on the left or right side of the same end of the cell module 502, thereby improving the testing flexibility and compatibility of the cell module testing mechanism, as well as the testing efficiency of the cell module 502.

[0085] To optimize the above technical solution, the OCV test assembly 200 includes a third driver 201, a fourth connecting plate 202, and a first test probe 203. The fourth connecting plate 202 is perpendicular to and connected to the third connecting plate 703. The fourth connecting plate 202 is connected to the third driver 201, which in turn is connected to the first test probe 203, driving the first test probe 203 to move vertically. The first test probe 203 contacts the total positive and total negative terminals of the cell module 502. Specifically, the third driver 201 is preferably a slide cylinder, and the OCV test is a test of the voltage internal resistance of the cell module 502. Specifically, the third connecting plate 703 and the fourth connecting plate 202 form an L-shaped structure to facilitate the third driver 201 driving the first test probe 203 to move vertically. In use, both adjusting plates 503 and two third connecting plates 703 move to preset positions. The two third drivers 201 respectively drive the two first test probes 203 downwards. The two first test probes 203 respectively contact the total positive and total negative terminals of the cell module 502 to complete the OCV test. This arrangement enables the automation of OCV testing, reduces labor costs in testing, and improves the testing efficiency of the cell module 502.

[0086] To optimize the above technical solution, the first insulation test assembly 300 includes a fourth driver 301, a fifth connecting plate 302, and a second test probe. The fifth connecting plate 302 is perpendicular to and connected to the third connecting plate 703. The fifth connecting plate 302 is connected to the fourth driver 301, which in turn is connected to the second test probe, driving the second test probe to move vertically. The second test probe is used to contact the total positive and total negative terminals of the battery cell module 502. Specifically, the fourth driver 301 is preferably a slide cylinder. The third connecting plate 703 and the fifth connecting plate 302 form an L-shaped structure to facilitate the fourth driver 301 driving the second test probe to move vertically. The fifth connecting plate 302 and the fourth connecting plate 302 are arranged on opposite sides of the adjusting plate 503, and the fourth driver 301 and the third driver 301 are arranged back-to-back. In use, the insulation test of the cell module 502 is divided into an insulation test between the positive terminal of the cell module 502 and the end plate of the cell module 502, and an insulation test between the negative terminal of the cell module 502 and the end plate of the cell module 502. During the insulation test, the second insulation test assembly 400 is connected to the end plate of the cell module 502, and the fourth driver 301 drives the second test probe downward. The second test probe contacts the positive or negative terminal of the cell module 502 to complete the two insulation tests. This arrangement can automate the insulation test, reduce the labor cost in the test, and improve the testing efficiency of the cell module 502.

[0087] To optimize the above technical solution, the battery cell module testing mechanism also includes an end positioning mechanism 800 and a side positioning mechanism 900. There are two end positioning mechanisms 800, which are arranged opposite to each other at the first and second ends of the base 500. The two end positioning mechanisms 800 are used to position the two ends of the battery cell module 502, respectively. There are two side positioning mechanisms 900, which are arranged opposite to each other on the first and second sides of the base 500. The two side positioning mechanisms 900 are used to position the two sides of the battery cell module 502, respectively. Specifically, the first end of the base 500 is one end in the forward direction of the battery cell module 502 during transportation, the second end of the base 500 is the rear end of the battery cell module 502 during transportation, the first side of the base 500 is the left side perpendicular to the forward direction of the battery cell module 502 during transportation, and the second side of the base 500 is the right side perpendicular to the forward direction of the battery cell module 502 during transportation. That is, the end positioning mechanism 800 and the side positioning mechanism 900 are used to position the four sides of the battery cell module 502 except for the top and bottom surfaces, so as to fix the position of the battery cell module 502, which facilitates the barcode scanner to capture and scan the information on the tooling plate 501. At the same time, it facilitates the adjustment of the relative position of the first moving component 600 and the second moving component 700 with the battery cell module 502, and facilitates the alignment of the first test probe 203 and the second test probe with the preset position of the battery cell module 502, thereby improving the detection efficiency of the battery cell module 502.

[0088] To optimize the above technical solution, the end positioning mechanism 800 includes a lifting cylinder 801, a lifting plate, a telescopic cylinder 802, a telescopic plate, and a contact member 803. The lifting cylinder 801 is connected to the lifting plate and drives the lifting plate to move vertically. The telescopic cylinder 802 is arranged on the top of the lifting plate, and the telescopic plate connects the telescopic cylinder 802 and the contact member 803. The telescopic cylinder 802 drives the contact member 803 to move horizontally. When the telescopic cylinder 802 is in the extended state, the contact member 803 abuts against the end of the battery cell module 502. Specifically, the lifting cylinder 801 has a vertically positioned buffer member to buffer the vibration of the lifting plate and to limit its movement. The telescopic cylinder 802 has a horizontally positioned buffer member to buffer the vibration of the telescopic plate and to limit its movement. In use, when the battery cell module 502 arrives at the testing station, the lifting cylinders 801 of the two end positioning mechanisms 800 are extended, and the telescopic cylinder 802 reaches a preset height. Then, the telescopic cylinder 802 extends, and the two abutting members 803 abut against the first and second ends of the battery cell module 502 respectively, thereby positioning the battery cell module 502 in the forward direction of its transport. Specifically, the abutting members 803 can be of any shape; preferably, two are arranged opposite each other on the telescopic plate to stably abut against the battery cell module 502. By arranging the lifting cylinders 801 and the telescopic cylinders 802, the end positioning mechanism 800 does not affect the transport process of the battery cell module 502 when positioning is not required, and can flexibly adjust the abutting position when positioning is needed. This allows the end positioning mechanism 800 to be applied to battery cell modules 502 of various sizes, improving the flexibility and compatibility of the battery cell module testing mechanism.

[0089] To optimize the above technical solution, the second insulation test assembly 400 includes a fifth driver 401, a sixth connecting plate 402, and a third test probe 403. The sixth connecting plate 402 connects the fifth driver 401 and the third test probe 403. The fifth driver 401 is connected to a telescopic plate and drives the third test probe 403 to move horizontally. The third test probe 403 contacts the end plate of the battery cell module 502. Specifically, the fifth driver 401 is preferably a slide cylinder. It should be noted that a preferred embodiment is that the second insulation test assembly 400 is fixedly connected to the end positioning mechanism 800 to flexibly adjust the position of the third test probe 403. When the second insulation test assembly 400 is fixedly connected to the end positioning mechanism 800, the second insulation test assembly 400 can be fixed between the two opposing abutment members 803, and a connecting component is used to connect the fifth driver 401 to the telescopic plate. Specifically, the sixth connecting plate 402 is L-shaped, with one end connected to the fifth driver 401 and the other end connected to the third test probe 403. In use, when the abutment 803 abuts against the end of the cell module 502, the fifth driver 401 is in an extended state, and the third test probe 403 is connected to the end plate of the cell module 502 to cooperate with the first test probe 203 and the second test probe to complete the two insulation tests mentioned above. This arrangement allows for flexible movement of the relative position between the second insulation test assembly 400 and the cell module 502, thereby improving the compatibility of insulation testing and the testing efficiency of the cell module 502.

[0090] To optimize the above technical solution, the side positioning mechanism 900 includes a limiting cylinder 901, a limiting plate 902, and a limiting member 903. The limiting cylinder 901 is connected to the base 500 and to the limiting plate 902, used to move the limiting plate 902 horizontally. The limiting member 903 is fixed to the limiting cylinder 901, used to limit the movement path of the limiting plate 902. When the limiting cylinder 901 is in the extended state, the limiting plate 902 abuts against the side of the battery cell module 502. Specifically, a support frame is connected below the limiting cylinder 901, and the support frame is fixed to the base 500, so that the initial position of the limiting cylinder 901 has a certain height. Specifically, the limiting member 903 and the aforementioned buffer components include, but are not limited to, hydraulic buffers. In use, when the battery cell module 502 arrives at the testing station, the limiting cylinders 901 of the two side positioning mechanisms 900 are both in the extended state. The two limiting plates 902 abut against the first and second sides of the battery cell module 502 respectively, and together with the two abutting parts 803, the battery cell module 502 is fixed on four sides. On the one hand, this facilitates the adjustment of the relative position of the first moving component 600 and the second moving component 700 with the battery cell module 502, and on the other hand, it ensures the stability of the battery cell module 502 during testing and improves the testing efficiency of the battery cell module 502.

[0091] To optimize the above technical solution, the cell module testing mechanism also includes an OCV tester 504 and an insulation tester 505. The OCV tester 504 is connected to the OCV testing assembly 200 and outputs the test data from the OCV testing assembly 200. The insulation tester 505 is connected to the first insulation testing assembly 300 and the second insulation testing assembly 400 and outputs the test data from both. Both the OCV tester 504 and the insulation tester 505 are fixedly connected to the base 500. Specifically, the OCV tester 504 is wired to the first test probe 203 in the OCV testing assembly 200, and the insulation tester 505 is wired to the second test probe in the first insulation testing assembly 300 and the third test probe 403 in the second insulation testing assembly 400. The OCV testing assembly 200 acts as a contact head for the OCV tester 504, and its test results are output through the OCV tester 504 and uploaded to the manufacturing execution system. Specifically, the module information scanned by the aforementioned barcode scanner can also be uploaded to the manufacturing execution system to record the working information of the cell module testing mechanism. Specifically, in actual use, the positions of the OCV tester 504 and the insulation tester 505 can be adjusted according to usage needs. They can be fixed at any position within the cell module testing mechanism that can be connected to the OCV test assembly 200, the first insulation test assembly 300, and the second insulation test assembly 400, to adapt to the overall structure of the cell module testing mechanism, making the cell module testing mechanism structurally compact.

[0092] In summary, the operation of the battery cell module testing mechanism is as follows: the battery cell module 502 enters the testing mechanism via a track; a barcode scanner reads the module information on the tooling plate 501 of the battery cell module 502; the end positioning mechanism 800 and the side positioning mechanism 900 position the battery cell module 502; the first moving component 600 of the form-changing device moves to a preset position, and the second moving component 700 moves to a preset position; the battery cell module testing mechanism performs OCV testing and / or insulation testing and uploads the results to the manufacturing execution system; the end positioning mechanism 800 and the side positioning mechanism 900 cancel the positioning, and the battery cell module 502 proceeds to the next process along the conveying direction. This process achieves automated OCV and insulation testing of battery cell modules 502 with different module information, replacing manual inspection and improving the testing flexibility and compatibility of the battery cell module testing mechanism, as well as the testing efficiency of the battery cell module 502.
