Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery production equipment technology, specifically to a blade battery OCV test probe module. Background Technology
[0002] Battery module OCV refers to the battery open-circuit voltage, which is the voltage difference between the positive and negative terminals when the battery circuit is not open. To improve testing efficiency, companies need to test the battery module's OCV simultaneously with the withstand voltage test. Existing testing devices typically use a one-by-one testing method or manual testing of each cell, resulting in low efficiency. Similarly, conventional OCV testing, considering the number of tests per cycle, employs single-channel multiple switching tests, frequently using relays, leading to cumbersome wiring, interference from frequent switching, and a long overall testing time. Furthermore, since the thickness of each battery in the user's tray may vary, the probe components (temperature probe, casing probe) are difficult to integrate and press onto the battery terminals during OCV testing, resulting in poor adaptability of existing OCV test probe modules. Therefore, improvements are needed. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention proposes a blade battery OCV test probe module that enables simultaneous testing of multiple blade batteries, greatly improving testing efficiency. Furthermore, even when the thickness of each battery in the user's tray is inconsistent, the OCV test probe (temperature probe, casing probe) assembly can be compatible and pressed onto the battery terminals on both sides, enhancing the adaptability of the probe module.
[0004] To achieve the above technical solution, this utility model provides a blade battery OCV test probe module, comprising: a module mounting frame, a probe module mounting plate mounted on the back of the module mounting frame, a probe assembly X-axis guide rail mounted on the probe module mounting plate, multiple probe assemblies mounted in parallel at intervals on the probe assembly X-axis guide rail, adjacent probe assemblies connected at their backs by an elongated hole connecting plate, each probe assembly having an elongated hole fixing screw mounted on its back, the elongated hole fixing screw being inserted into the elongated hole of the elongated hole connecting plate, a probe assembly spring mounted between the sides of adjacent probe assemblies, an electric cylinder push block mounted on the left side of the first probe assembly, a tray liner detection photoelectric sensor mounted on the electric cylinder push block and positioned facing forward along the Y direction, a probe module push-pull electric cylinder mounted on the module mounting frame and connected to the electric cylinder push block, and an X-axis adjusting bolt mounted on the right side of the probe assembly X-axis guide rail.
[0005] In the above technical solution, during actual operation, the photoelectric sensor for detecting the tray liner moves via the push-pull cylinder of the probe module. After detecting the tray liner, the push-pull cylinder of the probe module stops pushing (the probe assembly spacing varies depending on the spacing between the tray batteries; the minimum probe spacing is 34.6mm, and the maximum is 46mm. The distance between the tray batteries is automatically adjusted by the movement position of the last tray liner combined with photoelectric sensing). Since springs are installed between adjacent probe assemblies, the distance between each probe assembly is the same. Therefore, the concave guide block can be introduced only when the thickness of each row of batteries in the tray is the same (or the battery thickness deviation is small). This allows for the simultaneous detection of multiple blade batteries, greatly improving detection efficiency. At the same time, even when the thickness of each battery in the user's tray is inconsistent, the OCV test probe (temperature probe, shell probe) assembly can be compatible and pressed onto the battery terminals on both sides, improving the adaptability of the probe module.
[0006] Preferably, the probe assembly includes a probe mounting bracket, with slider mounting plates mounted on both the top and bottom of the bracket. A slider is mounted on the back of the slider mounting plate. The probe mounting bracket is embedded in the probe assembly X-guide rail on the probe module mounting plate via the slider. A guide block mounting seat is mounted on the top of the bracket, with a concave guide block mounted at the front end. A compression spring is installed between the concave guide block and the guide block mounting seat. A housing probe is mounted on the front side of the bracket, a temperature probe is mounted below the housing probe, and two parallel, spaced-apart electrode probes are mounted below the temperature probe. In actual operation, the concave guide block is used to position each probe assembly for insertion. The housing probe, temperature probe, and electrode probes are used to mate with the battery casing, cell, and electrode, respectively.
[0007] Preferably, two parallel Y-guide rails are installed at intervals along the X-axis below the module mounting bracket. The module mounting bracket is mounted on the Y-guide rails via a module mounting bracket slider. A Y-axis push-pull cylinder mounting seat is also installed at the rear of the module mounting bracket, and a Y-axis push-pull cylinder is mounted on the mounting seat. The telescopic shaft of the Y-axis push-pull cylinder is connected to the bottom of the module mounting bracket. In actual operation, the Y-axis push-pull cylinder can push the module mounting bracket and the entire probe module together into position along the Y-axis, allowing the probe module to perform probe crimping with the battery, thus achieving the testing docking of the battery with each probe component. After all batteries have been crimped and tested, the Y-axis push-pull cylinder then drives the module mounting bracket to retract, completing the testing function.
[0008] Preferably, the top of the probe mounting bracket of the last probe assembly is equipped with a concave guide block detection photoelectric sensor positioned along the X direction directly opposite the concave guide block to detect whether each concave guide block is properly inserted during the actual test.
[0009] Preferably, the probe mounting bracket has multiple spring mounting holes on both the left and right sides. One end of the probe assembly spring is inserted into the spring mounting hole. In actual operation, the function of the probe assembly spring is to ensure that the distance between each probe assembly is the same.
[0010] The beneficial effects of the blade battery OCV test probe module provided by this utility model are as follows: This blade battery OCV test probe module has a high degree of automation and intelligence, and can realize the one-time testing of multiple blade batteries, which greatly improves the testing efficiency. At the same time, even when the thickness of each battery in the user tray is different, the OCV test probe (temperature probe, shell probe) components can be compatible and pressed onto the battery terminals on both sides, which improves the adaptability of the probe module.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: A blade battery OCV test probe module.
[0018] Reference Figures 1 to 4 As shown, a blade battery OCV test probe module includes: a module mounting frame 3, with two parallel Y-guide rails 1 spaced apart along the X-axis mounted below the module mounting frame 3. The module mounting frame 3 is mounted on the Y-guide rails 1 via a module mounting frame slider 2. A Y-axis push-pull cylinder mounting seat 8 is also mounted behind the module mounting frame 3, and a Y-axis push-pull cylinder 7 is mounted on the Y-axis push-pull cylinder mounting seat 8. The telescopic shaft of the Y-axis push-pull cylinder 7 is connected to the bottom of the module mounting frame 3. In actual operation, the Y-axis push-pull cylinder 7 can push the module mounting frame 3 and the entire probe module together into position along the Y-axis, allowing the probe module to perform probe crimping with the battery, realizing the test docking of the battery with each probe component 6. After all batteries have been crimped and tested, the Y-axis push-pull cylinder 7 drives the module mounting frame 3 to retract, completing the testing function.
[0019] The back of the module mounting bracket 3 is equipped with a probe module mounting plate 5. Two probe assembly X-guide rails 13, arranged parallel and spaced along the Z-axis, are mounted on the probe module mounting plate 5. Multiple probe assemblies 6 are mounted parallel and spaced on the probe assembly X-guide rails 13. The backs of adjacent probe assemblies 6 are connected by elongated hole connecting plates 9. Each probe assembly 6 has an elongated hole fixing screw 10 mounted on its back. The elongated hole fixing screw 10 is inserted into the elongated hole of the elongated hole connecting plate 9. This allows for mutual pushing or pulling between adjacent probe assemblies 6. The sides of adjacent probe assemblies 6 are also connected. The probe assembly spring 17 is installed to ensure that the distance between each probe assembly 6 is the same. An electric cylinder push block 15 is installed on the left side of the first probe assembly 6. A tray liner detection photoelectric sensor 11 is installed on the electric cylinder push block 15 and is positioned facing forward along the Y direction. The tray liner detection photoelectric sensor 11 is used to detect the tray liner. The probe module push-pull electric cylinder 4 is installed on the module mounting bracket 3 and connected to the electric cylinder push block 15. An X-direction adjusting bolt 12 is installed on the right side of the probe assembly X guide rail 13 to limit the movement position of the rightmost probe assembly 6 and to make fine adjustments. In actual operation, the tray liner detection photoelectric sensor 11 moves along with the electric cylinder push block 15 pushed by the probe module push-pull electric cylinder 4. When the tray liner detection photoelectric sensor 11 detects the tray liner, the probe module push-pull electric cylinder 4 stops pushing. Since probe assembly springs 17 are installed between adjacent probe assemblies 6, the distance between each probe assembly 6 is the same. Therefore, the concave guide block 67 on the probe assembly 6 can be introduced when the thickness of each row of batteries in the tray is the same.
[0020] Reference Figure 4As shown, the probe assembly 6 includes a probe mounting bracket 61. Slider mounting plates 62 are mounted on the top and bottom of the probe mounting bracket 61. A slider 63 is mounted on the back of the slider mounting plate 62. The probe mounting bracket 61 is embedded in the probe assembly X-guide rail 13 on the probe module mounting plate 5 via the slider 63. A guide block mounting seat 65 is mounted on the top of the probe mounting bracket 61. A concave guide block 67 is mounted on the front end of the guide block mounting seat 65, and a compression spring 66 is installed between the concave guide block 67 and the guide block mounting seat 65. A housing probe 68 is mounted on the front side of the probe mounting bracket 61. A temperature probe 69 is mounted below the housing probe 68. Two parallel and spaced electrode probes 610 are mounted below the temperature probe 69. In actual operation, the concave guide block 67 is used to insert and position each probe assembly 6. The housing probe 68, temperature probe 69, and electrode probe 610 are used to mate with the battery casing, cell, and electrode, respectively. The last probe assembly 6 has a probe mounting bracket 61 with a concave guide block detection photoelectric sensor 16 mounted on top, positioned along the X-direction and directly opposite the concave guide block 67, to detect whether each concave guide block 67 is properly inserted during the actual test. Multiple spring mounting holes 64 are provided on both the left and right sides of the probe mounting bracket 61. One end of the probe assembly spring 17 is inserted into the spring mounting hole 64. In actual operation, the function of the probe assembly spring 17 is to ensure that the distance between each probe assembly 6 is the same.
[0021] This blade battery OCV test probe module is highly automated and intelligent, enabling simultaneous testing of multiple blade batteries and significantly improving testing efficiency. In actual operation, the tray liner detection photoelectric sensor 11 moves via the probe module push-pull cylinder 4. Once the tray liner detection photoelectric sensor 11 detects the tray liner, the probe module push-pull cylinder 4 stops pushing (the probe assembly spacing varies depending on the tray battery spacing; the minimum probe spacing is 34.6mm, and the maximum is 46mm. The distance between the probes is automatically adjusted by the movement of the last tray liner combined with photoelectric sensing). Because probe assembly springs 17 are installed between adjacent probe assemblies 6, the distance between each probe assembly 6 is equal. Therefore, ensuring that the thickness of each row of batteries in the tray is the same allows the concave guide block 67 on the probe assembly 6 to be inserted. Then, the Y-axis push-pull cylinder 7 pushes the module mounting bracket 3 and the entire probe module together into position along the Y-axis, allowing the probe module to be probed into contact with the battery, achieving the test docking between the battery and each probe assembly 6. After all batteries have been crimped and tested, the Y-axis push-pull cylinder 7 drives the module mounting bracket 3 to retract, and then the probe module push-pull cylinder 4 pulls all probe assemblies 6 back to their original positions, completing the testing function. This allows for the simultaneous testing of multiple blade batteries, greatly improving testing efficiency. Furthermore, even when the thickness of each battery in the user's tray is inconsistent, the OCV test probes (temperature probes, casing probes) can be compatible and crimped onto the battery terminals on both sides, improving the adaptability of the probe module.
[0022] The above description is only a preferred embodiment of the present utility model. However, the present utility model should not be limited to the content disclosed in the embodiment and the accompanying drawings. Therefore, any equivalent or modified embodiments made without departing from the spirit disclosed in the present utility model shall fall within the protection scope of the present utility model.
