Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to a battery module polarity detection probe moving device. Background Technology

[0002] A battery module consists of multiple cells, each with positive and negative terminals. During the production, assembly, and testing of the battery module, it is essential to ensure that the positive and negative terminals of each cell are correctly connected. Polarity detection can promptly identify and correct connection errors, preventing performance degradation or damage to the battery module during subsequent use.

[0003] For example, patent CN214122429U discloses a polarity detection fixture for lithium battery modules. By setting up diode lights and a first metal probe and a second metal probe, the positive and negative terminals of the diode lights are connected to the positive and negative terminals of each battery cell through the first metal probe and the second metal probe, respectively. Each battery cell is connected to a diode light. By observing whether the diode lights are lit, the polarity of the battery cells in the module can be determined. The operation is simple and easy to repair and replace. At the same time, it also solves the error caused by the visual fatigue of employees, avoids the outflow and scrapping of abnormal products, and greatly saves costs.

[0004] The above solution involves installing multiple polarity detection devices on a bracket and using the diode lamps and metal probes of the polarity detection devices to detect the positive and negative terminals of the battery cell. However, because the polarity detection devices are fixed in position on the bracket, this testing fixture can only be used for battery modules of a certain size and has poor versatility.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3As shown, a battery module polarity detection probe moving device includes a fixed frame 1, a slider 7, a lifting structure for adjusting the height of the fixed frame 1, and a moving structure for adjusting the corresponding position of the slider 7. The moving structure includes a screw 2 and a slide rod 3. The two ends of the screw 2 have threaded grooves with opposite thread directions. The screw 2 and the slide rod 3 are arranged parallel to the fixed frame 1 along the width direction. The screw 2 is rotatably connected to the fixed frame 1. One end of the screw 2 is fixedly connected to a motor (not shown in the figure) that drives its rotation. The two ends of the screw 2 are respectively threadedly connected to a first moving plate 4 and a second moving plate 5. The slide rod 3 passes through the first moving plate 4 and the second moving plate 5 and is slidably connected to them for limiting. When the motor is started, the screw 2 rotates. The first moving plate 4 and the second moving plate 5, which are threaded to the two ends of the screw 2, move towards each other. The first moving plate 4 and the second moving plate 5 move the probe body 9 on them closer to each other or further away. The distance between the positive and negative electrodes detected by the probe body 9 can be adjusted. 4 and the movable plate 5 are equipped with several sliders 7 that slide horizontally and are vertically connected to the drive plate 10. Each slider 7 has a probe body 9 that can be detachably connected to its bottom. Each slider 7 has a drive block 12 on the side near the drive plate 10. The drive plate 10 has several guide grooves 11. The guide grooves 11 can be set according to actual requirements. When the drive plate 10 moves up and down, the guide grooves 11 can guide multiple drive blocks 12 to make horizontal equidistant adjustments. The drive blocks 12 are slidably connected in the corresponding guide grooves 11. The top of the fixed frame 1 is equipped with a drive structure that makes the drive plate 10 move up and down. When the drive structure drives the drive plate 10 to move up and down, the guide grooves 11 can drive the drive blocks 12 to slide left and right along their grooves. While the drive blocks 12 slide, they drive the sliders 7 and the probe bodies 9 to move synchronously. This can realize the distance adjustment between the probe bodies 9. It is suitable for battery modules of different specifications and sizes and has strong versatility.

[0024] In some specific implementation plans, such as Figure 1 As shown, in order to facilitate the downward movement of the probe body 9 to test the battery cell, the lifting structure includes a lifting frame 16 and a driver 17. The lifting frame 16 is fixedly connected to the top of the fixed frame 1. Multiple drivers 17 are provided, and the driving ends of the drivers 17 are all fixedly connected to the lifting frame 16. When the drivers 17 are started synchronously, the driving ends of the drivers 17 can drive the lifting frame 16 and the fixed frame 1 to move up and down to get closer to the battery cell for testing.

[0025] In some specific implementation plans, such as Figure 3 As shown, in order to facilitate the slider 7 to drive the probe body 9 to slide left and right, the first movable plate 4 and the second movable plate 5 are both horizontally arranged with several parallel slide rails 6 on the side near the drive plate 10. The slider 7 is provided with a groove corresponding to the slide rail 6. The slider 7 is slidably connected to the slide rail 6, and the slider 7 can drive the corresponding probe body 9 to slide left and right.

[0026] In some specific implementation plans, such as Figure 2 As shown, in order to facilitate the stable lifting and lowering of the drive plate 10, T-shaped rods 19 are vertically arranged at both ends of the movable plate 11 4 and the movable plate 2 5 on the side close to the drive plate 10. The drive plate 10 is provided with T-shaped grooves 18 corresponding to the T-shaped rods 19, and the T-shaped grooves 18 are slidably connected to the T-shaped rods 19.

[0027] In some specific implementation plans, such as Figure 2 or Figure 3 As shown, in order to facilitate the up and down movement of the drive plate 10, the drive structure includes a connecting rod 14. The top of the drive plate 10 is provided with a vertical plate 13. Lifting cylinders 15 are symmetrically arranged on the upper surface of the rods on both sides of the fixed frame 1. The drive ends of the two lifting cylinders 15 are connected to the connecting rod 14. The connecting rod 14 passes through the vertical plate 13 and is slidably connected to the vertical plate 13. When the lifting cylinders 15 are started simultaneously, the connecting rod 14 is driven to lift and lower, which can drive the drive plate 10 and the vertical plate 13 to lift and lower. By sliding the vertical plate 13 and the connecting rod 14, the movement of the moving plate 1 4 and the moving plate 2 5 is not affected.

[0028] In some specific implementation plans, such as Figure 3 As shown, for easy maintenance, the bottom of the slider 7 is connected to the mounting block 8 by screws or clips, and the probe body 9 is installed on the bottom of the corresponding mounting block 8. When the probe body 9 is damaged, the mounting block 8 can be removed and replaced without replacing the slider 7, thus saving maintenance costs.

[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0030] The starter motor drives the screw 2 to rotate. The moving plate 4 and the moving plate 5, which are threaded to both ends of the screw 2, move towards each other. The moving plate 4 and the moving plate 5 drive the probe body 9 on them to move closer or further apart, which can adjust the distance between the positive and negative terminals detected by the probe body 9. Then, the lifting cylinder 15 is started synchronously to drive the connecting rod 14 to move up and down, which can drive the drive plate 10 and the vertical plate 13 to move up and down. When the drive structure drives the drive plate 10 to move up and down, the guide groove 11 can drive the drive block 12 to slide left and right along its groove. While the drive block 12 slides, it drives the slider 7 and the probe body 9 to move synchronously, which can realize the distance adjustment between adjacent probe bodies 9. It is suitable for battery modules of different specifications and sizes, and has strong versatility. The bottom of the slider 7 is connected to the mounting block 8 by screws or buckles. Each mounting block 8 is equipped with a probe body 9 at the bottom. When the probe body 9 is damaged, the mounting block 8 can be removed and replaced without replacing the slider 7, saving maintenance costs.
