Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery testing technology, specifically to an electrode plate testing device for battery testing. Background Technology
[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. It is a cup, tank, or other container or composite container. Batteries have positive and negative electrodes, meaning the battery pack contains electrode plates. During battery pack recycling and repair, the main focus is on inspecting and repairing any damage to the electrode plates.
[0003] In typical battery refurbishment and repair processes, it's necessary to control the battery testing device to contact the battery plate. By energizing the electrode plates and observing their voltage values, damage can be detected. However, testing the battery plate requires disassembling the battery pack, which is time-consuming. Furthermore, if the electrode plate is damaged, disassembly and repair are unnecessary. Therefore, in electrode plate testing, the testing device is moved inside the battery pack and controlled to contact the electrode plate. However, this method can only test one electrode plate at a time. Since different battery packs contain multiple electrode plates, testing only one plate at a time affects efficiency. Therefore, we propose an electrode plate testing device for battery testing. Utility Model Content
[0004] To address the shortcomings of existing electrode plate testing devices for battery testing, this invention provides an electrode plate testing device for battery testing. This device features the advantage of simultaneously contacting and testing multiple sets of electrode plates by adjusting the position of the detection contact according to the different positions of the electrode plates, thereby improving the electrode plate testing efficiency and solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: an electrode plate testing device for battery testing, including a crossbar, an installation groove is provided inside the crossbar, a limiting sleeve is movably installed inside the installation groove, an installation sleeve is movably sleeved inside the limiting sleeve, a slider is movably sleeved on the inner side of the crossbar, a screw is fixedly connected to the inner side of the slider, a telescopic sleeve is threaded onto the outer side of the screw, and a connecting sleeve is movably sleeved on the outer side of the telescopic sleeve in the middle.
[0006] Preferably, a fastening bolt is installed on one side of the limiting sleeve, the fastening bolt passes through the limiting sleeve and is in close contact with the side of the crossbar, and six sets of the limiting sleeve are installed inside the mounting groove.
[0007] Preferably, a connecting rod is installed inside the mounting sleeve, a detection contact is fixedly connected to the lower part of the connecting rod, and a threaded sleeve is installed on the external thread of the lower end of the mounting sleeve, the threaded sleeve being movably sleeved on the outside of the lower end of the detection contact.
[0008] Preferably, a connecting wire is installed on the outside of the connecting rod, and the connecting wire is installed on the testing equipment.
[0009] Preferably, a spring is fitted onto the outside of the mounting sleeve, and a sealing sleeve is fixedly connected between the limiting sleeve and the bottom end of the mounting sleeve, with the sealing sleeve fitted onto the outside of the spring.
[0010] Preferably, the screw is installed on both sides of the telescopic sleeve, and a control handle is fixedly connected to the middle of the connecting sleeve. The control handle is installed in the middle of the connecting sleeve.
[0011] Preferably, a sprocket is fixedly connected to the outside of the telescopic sleeve, and a chain is sleeved on the outside of the sprockets at both ends.
[0012] Compared with existing electrode plate testing devices for battery testing, this utility model has the following advantages:
[0013] 1. The electrode plate detection device for battery testing allows for adjustment of the position of the detection contacts inside the mounting groove. Specifically, the position of the limiting sleeve inside the mounting groove is adjusted according to the different positions of the battery plate inside the battery pack. At the same time, the telescopic sleeve is rotated to adjust the distance between the two sets of crossbars, thereby controlling the limiting sleeve to drive multiple sets of detection contacts to contact the electrode plate, which improves work efficiency.
[0014] 2. The electrode plate detection device for battery testing is fitted inside the limiting sleeve by an installation sleeve. The installation sleeve is pushed downward by the elasticity of the spring. That is, depending on the position of the electrode plate inside the battery pack, the detection contact can be moved to the inside of the electrode plate and simultaneously contact the electrode plate at different heights. This avoids the inability to accurately determine whether the detection contact is in contact with the electrode plate when the detection contact is simultaneously in contact with the electrode plate installed inside the battery pack, which would affect the detection results.

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A battery testing electrode plate testing device includes a crossbar 1. An installation groove 2 is provided inside the crossbar 1, providing space for a limiting sleeve 3. The limiting sleeve 3 is movably installed inside the installation groove 2, and its position within the groove is adjustable. An installation sleeve 5 is movably fitted inside the limiting sleeve 3, allowing for telescopic adjustment within the limiting sleeve 3. A slider 11 is movably fitted inside the crossbar 1, and a screw 12 is fixedly connected to its inner side. A telescopic sleeve 13 is threadedly fitted onto the outer side of the screw 12. Rotating the telescopic sleeve 13 causes threaded movement between it and the screw 12, thus controlling the adjustment of the distance between the two sets of crossbars 1. By adjusting the position of the detection contacts 7, multiple sets of detection contacts 7 can be simultaneously extended into the battery pack depending on the electrode plate position, allowing for detection of electrode plate damage. A connecting sleeve 16 is movably fitted onto the outer side of the telescopic sleeve 13.
[0023] Please see Figure 5 A fastening bolt 4 is installed on one side of the limiting sleeve 3. The fastening bolt 4 passes through the limiting sleeve 3 and is in close contact with the side of the crossbar 1. Six sets of limiting sleeves 3 are installed inside the mounting groove 2. The mounting groove 2 is provided on the crossbar 1. The position and number of limiting sleeves 3 inside the mounting groove 2 are adjusted according to the different spacing of the battery panels installed inside the battery pack. At the same time, the fastening bolt 4 is rotated. The fastening bolt 4 drives the limiting sleeve 3 to be spliced and limited outside the crossbar 1 to ensure that the position of the limiting sleeve 3 outside the crossbar 1 is adjustable.
[0024] Please see Figure 3 The mounting sleeve 5 has a connecting rod 6 installed inside. A detection contact 7 is fixedly connected to the lower part of the connecting rod 6. A threaded sleeve 8 is installed on the external thread of the lower end of the mounting sleeve 5. The threaded sleeve 8 is movably sleeved on the outside of the lower end of the detection contact 7. The connecting rod 6 passes through the mounting sleeve 5. At the same time, the lower end of the connecting rod 6 is fixedly connected to the detection contact 7. The detection contact 7 is located at the lower end of the mounting sleeve 5. When the threaded sleeve 8 is rotated, the threaded sleeve 8 drives the detection contact 7 to be spliced and limited at the lower end of the mounting sleeve 5, ensuring that the connecting rod 6 can be easily spliced and limited inside the mounting sleeve 5.
[0025] Please see Figure 1 A connecting wire is installed on the outside of the terminal block 6. The connecting wire is installed on the testing equipment. By controlling the detection contact 7 to contact the electrode to be tested, the electrode can be tested for damage by detecting the electrode resistance and voltage intensity.
[0026] Please see Figure 3 A spring 9 is fitted onto the outside of the mounting sleeve 5. A sealing sleeve 10 is fixedly connected between the limiting sleeve 3 and the bottom of the mounting sleeve 5. The sealing sleeve 10 is fitted onto the outside of the spring 9. The spring 9 pushes the mounting sleeve 5 downward, and at the same time controls the detection contact 7 to contact the electrode. According to the different positions of the electrode inside the battery pack, the elasticity of the spring 9 controls the extension and retraction adjustment of the detection contact 7 to ensure that the detection contact 7 contacts the length of the battery pack.
[0027] Please see Figure 1 The screw 12 is installed on both sides of the telescopic sleeve 13. The control handle 17 is fixedly connected to the middle of the connecting sleeve 16. The control handle 17 is installed in the middle of the connecting sleeve 16. By rotating the telescopic sleeve 13, the telescopic sleeve 13 and the screw 12 make threaded movements, which can control the distance between the two sets of crossbars 1 to be adjusted. When testing a battery pack with electrodes installed side by side, the distance between the two sets of crossbars 1 can be adjusted, and the control handle 17 can be controlled at the same time to move the detection contact 7 to extend into the battery. This allows multiple sets of electrodes to be tested at the same time, improving the electrode testing efficiency.
[0028] Please see Figure 4 The telescopic sleeve 13 is externally fixedly connected to a sprocket 14, and a chain 15 is sleeved on the outside of the sprockets 14 at both ends. The sprockets 14 are installed on both sides of the connecting sleeve 16. The sprockets 14 limit the position of the connecting sleeve 16. At the same time, when the telescopic sleeve 13 is rotated, the chain 15 drives the two sets of sprockets 14 to rotate synchronously, so as to ensure that the spacing between the two sets of crossbars 1 remains neat when adjusted.
[0029] Working principle: During use, the position of the limiting sleeve 3 inside the mounting groove 2 is adjusted according to the different positions of the electrodes installed inside the battery pack. At the same time, the position of the limiting sleeve 3 is limited by rotating the fastening bolt 4. Simultaneously, the telescopic sleeve 13 is rotated, and the chain 15 drives the two sets of sprockets 14 to rotate synchronously. That is, the telescopic sleeve 13 and the screw 12 perform threaded movement to ensure that the distance between the two sets of crossbars 1 remains the same. At the same time, the control handle 17 is held to control the detection contact 7 to extend into the inside of the battery pack and detect the contact 7 in contact with the electrode. According to the different positions of the electrodes, the spring 9 drives the mounting sleeve 5 to extend and retract inside the limiting sleeve 3 to ensure that each set of detection contacts 7 is in contact with the electrode. At the same time, the connection rod 6 is used to detect whether the electrode is damaged.
