Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing and testing technology, specifically relating to an instrument and device for measuring electrode gap. Background Technology

[0002] Battery electrode gap measurement refers to measuring the spatial distance between battery electrodes. This process is crucial for ensuring battery performance and safety. When testing electrode porosity, the first step is to select a suitable testing method. Currently, commonly used porosity testing methods include mercury intrusion porosimetry, gas adsorption, and image processing. Each method has its advantages and disadvantages, and the selection should be based on a comprehensive consideration of factors such as the electrode material, structure, and testing requirements. For example, mercury intrusion porosimetry is suitable for measuring materials with high porosity, but it may damage the electrode; gas adsorption has high accuracy, but its operation is relatively complex; image processing has the advantages of speed and simplicity, but its accuracy may be limited by factors such as image resolution and processing algorithms. Therefore, we propose an instrument for measuring electrode gap. Utility Model Content

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: an electrode gap measuring instrument device, including a fixed frame 1, a top plate 2 installed above the fixed frame 1, a cylinder 3 installed on the top of the top plate 2, a connecting shaft 4 provided at the bottom of the top plate 2, a pressure plate 5 provided at the bottom end of the connecting shaft 4, a pressure sensor 6 provided on the bottom surface of the pressure plate 5, a laser displacement sensor 7 installed on one side of the pressure plate 5, a base 8 installed below the fixed frame 1, a limiting cylinder 9 provided on the top of the base 8, a base 10 installed on one side of the base 8, a sliding groove 11 provided on the surface of the base 8, a bidirectional threaded rod 12 provided inside the sliding groove 11, a sliding rod 13 provided on the surface of the bidirectional threaded rod 12, and a clamping block 14 provided on one side of the sliding rod 13.

[0018] Specifically, the bottom output end of cylinder 3 is fixedly connected to the top end of connecting shaft 4. A pressure plate 5 is fixedly installed at the bottom end of connecting shaft 4. A limit cylinder 9 is fixedly connected to the top surface of base 8. Base 10 is located directly below laser displacement sensor 7, and the top surface of base 10 and base 8 are at the same plane height. The horizontal plane of the emitting end of laser displacement sensor 7 is at the same level as the bottom surface of pressure plate 5. A bidirectional threaded rod 12 is rotatably connected inside slide groove 11. One end of bidirectional threaded rod 12 extends rotatably to the outer end of base 8. Slide rods 13 are threadedly rotated at both ends of the surface of bidirectional threaded rod 12. Slide rods 13 are slidably disposed inside slide groove 11. A placement area 15 is provided in the middle of the surface of base 8. The placement area 15 is located in the upper middle of slide groove 11. A display control panel 16 is installed on one side of fixing frame 1.

[0019] In this embodiment, the battery is placed vertically inside the limiting cylinder 9, with the bottom electrode of the battery positioned in the center of the placement area 15. Then, by rotating the bidirectional threaded rod 12, the sliding rods 13 at both ends of the surface are moved towards the position of the placement area 15. The movement of the sliding rods 13 can cause the inner clamping block 14 to clamp the outer surface of the battery above the placement area 15, thereby improving the stability of the battery. The laser displacement sensor 7 is turned on, and the operation of the cylinder 3 can drive the connecting shaft 4 and the pressure plate 5 to move downward. When the pressure sensor 6 at the bottom of the pressure plate 5 contacts the electrode above the battery, the operation of the cylinder 3 will stop. At this time, the distance displayed between the emitting end of the laser displacement sensor 7 and the surface of the base 10 is the measurement data of the gap between the battery electrodes.
