Description

Technical Field

[0001] This utility model relates to the field of battery testing equipment technology, specifically to a device for testing the safety performance of alkaline batteries. Background Technology

[0002] Alkaline batteries, also known as alkaline dry batteries, alkaline zinc-manganese batteries, or alkaline manganese batteries, are the highest-performing type of zinc-manganese battery. They are suitable for applications requiring large discharge capacities and long operating times. Alkaline batteries are manufactured in individual cells or battery packs depending on the application. Battery packs can be connected in series or parallel. Parallel battery packs require each cell to have the same voltage, resulting in an output voltage equal to that of a single cell. Parallel battery packs can provide a stronger current. Series battery packs have fewer requirements. Currently, commonly used battery packs, especially those used in electric vehicles, boats, and other transportation vehicles, are mostly composed of two or more individual cells connected in series and parallel. During the battery pack manufacturing process, the battery packs are assembled... After being placed into the battery box, the battery box is closed tightly with the lid. At this point, the battery pack assembly is complete. However, during the assembly process, due to the materials themselves or human or machine operation errors, the product surface is easily cracked. Cracked batteries may leak electricity or electrolyte. Most existing testing devices require manual testing of the battery pack in multiple steps, and cannot perform synchronous testing during the conveying and unloading process. The battery pack may be damaged by collisions during the transfer between different processes, resulting in losses and reduced work efficiency. Furthermore, most existing battery testing bases do not have clamping and positioning mechanisms, resulting in poor stability of the battery pack during testing and affecting the battery pack test results.

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: an alkaline battery safety performance testing device, including a conveying mechanism 1, a testing mechanism 2, and a clamping and positioning mechanism 3. The conveying mechanism 1 includes a conveyor belt 4 and a drive assembly 5. The two ends of the conveyor belt 4 are respectively sleeved on the outer walls of the driving roller 6 and the driven roller 7, and the driving roller 6 and the driven roller 7 are fixedly mounted on the frame 9 through bearing seats 8. The drive assembly 5 includes a motor 10 and a reducer 11. The output shaft of the motor 10 is fixedly connected to the input end of the reducer 11 through a coupling. The output end of the reducer 11 is fixedly connected to one end of the driving roller 6. A plurality of limiting grooves 12 are equidistantly arranged on the conveyor belt 4. Furthermore, the inner walls of the limiting grooves 12 are all bonded with elastic pads 13. The detection mechanism 2 includes a pressure sensor module 14, a voltage detection module 15, and a leakage detection module 16. The pressure sensor module 14 is fixedly installed at the bottom of the crossbeam directly above the conveyor belt 4, and both ends of the crossbeam are fixed to the frame 9 by support columns. The pressure sensor module 14 includes several pressure sensor units 17, and each pressure sensor unit 17 corresponds to a position of a limiting groove 12. The voltage detection module 15 includes a probe group 18 and a signal processing unit 19. The probe group 18 is fixedly installed on the top of the side plates 20 on both sides of the conveyor belt 4, and the probe group 18... The probe tip extends above the limiting groove 12. The signal processing unit 19 is fixedly installed on one side of the frame 9 and electrically connected to the probe group 18. The leakage detection module 16 includes an absorbent cotton strip 21 and a humidity sensor 22. The absorbent cotton strip 21 is fixedly embedded in the bottom of the limiting groove 12 and connected to the humidity sensor 22 through a guide tube 23. The humidity sensor 22 is fixedly installed inside the frame 9 and electrically connected to the signal processing unit 19. The clamping and positioning mechanism 3 includes a clamping arm 24, a drive cylinder 25, and a guide assembly 26. The clamping arms 24 are symmetrically arranged on both sides of the conveyor belt 4, and the bottom end of the clamping arm 24 is connected to the frame 9 through a hinge seat. The drive cylinder 25 is fixedly installed on the outside of the frame 9, and the piston rod end of the drive cylinder 25 is hinged to the middle of the outer wall of the clamping arm 24. The guide assembly 26 includes a guide rod 27 and a slider 28. The guide rod 27 is fixedly installed on the inside of the clamping arm 24, and the slider 28 is sleeved on the outer wall of the guide rod 27 and slidably connected to the clamping arm 24. The slider 28 and the clamping arm 24 are connected by a spring 29. A rubber pad 30 is fixed to the inner end of the clamping arm 24, and the surface of the rubber pad 30 is evenly distributed with anti-slip protrusions. Through the above settings, the alkaline battery can be accurately clamped and positioned when it is stably transported on the conveyor belt 4. The drive cylinder 25 pushes the clamping arm 24, so that the rubber pad 30 fits tightly against the surface of the battery. The anti-slip protrusions increase the friction and effectively prevent the battery from sliding or falling off during the test. The guide rod 27 and slider 28 in the guide assembly 26 ensure the stability and accuracy of the clamping arm 24 during movement, while the spring 29 allows the clamping arm 24 to have a certain buffer when subjected to external force, avoiding damage to the battery.Once the battery is clamped and positioned, the detection mechanism 2 begins operation. The pressure sensor module 14 monitors the pressure on the battery in real time, ensuring uniform pressure and compliance with standards during the test. The voltage detection module 15 contacts the battery via probe group 18 to detect the battery's voltage state and evaluate its performance. The leakage detection module 16 absorbs any potential electrolyte leakage using absorbent cotton strips 21 and monitors humidity changes in real time via humidity sensor 22 to promptly detect battery leakage. The entire testing device is rationally designed, easy to operate, and can comprehensively and accurately evaluate the safety performance of alkaline batteries.

[0023] Furthermore, the elastic pad 13 is made of silicone. Through the above-mentioned configuration, the elastic pad 13 has good flexibility and wear resistance, which can provide effective cushioning and protection during battery transportation and prevent the battery from being damaged by collision or friction.

[0024] Furthermore, the probe assembly 18 includes a positive electrode probe 31 and a negative electrode probe 32, which are respectively located above the two sides of the limiting groove 12, with the probe tips extending to the center line of the limiting groove 12. This arrangement ensures that the positive electrode probe 31 and the negative electrode probe 32 can accurately align with the positive and negative electrodes of the battery, guaranteeing the accuracy and reliability of voltage detection. When the battery is transported into the limiting groove 12, the positive electrode probe 31 and the negative electrode probe 32 automatically contact the positive and negative electrodes of the battery without manual intervention, thus improving testing efficiency.

[0025] Furthermore, the pressure sensor unit 17 is fixedly installed at the bottom of the crossbeam with bolts, and the sensing surface of the pressure sensor unit 17 is set downwards. Through the above arrangement, the pressure sensor unit 17 can directly and accurately sense the pressure on the battery, thereby improving the accuracy and stability of pressure detection.

[0026] A specific application example of this embodiment is as follows:

[0027] In use, the alkaline battery is placed in the limiting groove 12 of the conveyor belt 4. Driven by the motor 10 and reducer 11, the conveyor belt 4 runs at a constant speed, carrying the alkaline battery sequentially through the detection mechanism 2 and the clamping and positioning mechanism 3. When the alkaline battery reaches below the pressure sensor module 14, the pressure sensor unit 17 applies a certain pressure to the top of the alkaline battery and detects whether there are cracks or deformations on its surface. Subsequently, the alkaline battery moves to the position of the voltage detection module 15, where the positive electrode probe 31 and the negative electrode probe 32 contact the positive and negative electrodes of the alkaline battery respectively, detecting its voltage value and transmitting the signal to the signal processing unit 19 for analysis. The absorbent swab 21 absorbs any liquid that may leak from the bottom of the alkaline battery and guides it to the humidity sensor 22 for detection via the guide tube 23. When the alkaline battery moves to the position of the clamping and positioning mechanism 3, the drive cylinder 25 pushes the clamping arm 24 to move inward. The rubber pad 30 at the end of the clamping arm 24 contacts the surface of the alkaline battery and applies a certain clamping force. The guide rod 27 and the slider 28, together with the spring 29, ensure the stability of the movement trajectory of the clamping arm 24, thereby achieving the clamping and positioning of the alkaline battery. Throughout the process, the alkaline battery can complete multiple tests without manual transfer, significantly improving work efficiency and detection accuracy.
