Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, and in particular to an auxiliary device for measuring the end height of a cylindrical steel-cased lithium-ion battery. Background Technology

[0002] Currently, steel-cased lithium-ion battery cells utilize a grooving process. Measuring the height of the grooved end requires the use of vernier calipers. However, manual caliper measurement frequently results in inconsistencies between measurements taken in different processes. Firstly, calipers cannot be fixed in the same position for repeated measurements by the same operator, leading to deviations and inconsistent dimensions. Furthermore, even when different personnel measure the same cell using different techniques, measurement deviations persist, causing further inconsistencies. Therefore, we propose an auxiliary device for measuring the height of cylindrical steel-cased lithium-ion batteries to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability of calipers to fix the same position and repeated measurements by the same operator, which leads to inconsistencies in the measured dimensions. Furthermore, even when different personnel measure the same battery cell using different methods, measurement deviations still occur, resulting in inconsistent measured dimensions. Therefore, this invention proposes an auxiliary device for measuring the end height of cylindrical steel-cased lithium-ion batteries.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary device for measuring the height of a cylindrical steel-cased lithium-ion battery includes a base, the top of which has a placement slot. The device further includes:

[0006] A cylindrical steel casing for a lithium battery, wherein the cylindrical steel casing for the lithium battery is placed inside a placement slot;

[0007] A stabilizing component is disposed inside the placement slot and cooperates with the cylindrical steel shell of the lithium battery.

[0008] The measuring assembly includes: a bracket, two electric actuators, a mounting tube, a digital vernier caliper, a second screw, two connecting rods, and an arc-shaped pressure plate. The bottom end of the bracket is fixedly mounted on the top of the base. The two electric actuators are both fixedly mounted on the bottom of the bracket. The top of the mounting tube is fixedly mounted to the output shafts of the two electric actuators respectively. The mounting tube can be detached and sleeved on the digital vernier caliper. The bottom end of the second screw passes through the top of the mounting tube and mates with the top of the digital vernier caliper. The second screw is threadedly connected to the mounting tube. The top ends of the two connecting rods are both fixedly mounted on the bottom of the mounting tube. The bottom ends of the two connecting rods are both fixedly mounted on the top of the arc-shaped pressure plate. The bottom of the arc-shaped pressure plate contacts the top of the cylindrical steel shell of the lithium battery.

[0009] In a preferred embodiment of this invention, an anti-slip block is fixedly installed at the bottom end of the second screw, and the bottom of the anti-slip block contacts the top of the digital vernier caliper.

[0010] As a preferred embodiment of this utility model, two support rollers are rotatably connected to the bottom inner wall of the placement groove, and the bottom of the cylindrical steel shell of the lithium battery is respectively rolledly connected to the two support rollers.

[0011] As a preferred embodiment of this utility model, the stabilizing component includes a right clamping plate, a first screw, and a left clamping plate. The right clamping plate is installed on the inner right side of the placement slot. The left side of the right clamping plate is engaged with the right end of the cylindrical steel shell of the lithium battery. The right end of the first screw penetrates the base and extends into the interior of the placement slot. The left side of the left clamping plate is rotatably connected to the right end of the first screw. The first screw is threadedly connected to the base. The right side of the left clamping plate is engaged with the left end of the cylindrical steel shell of the lithium battery.

[0012] As a preferred embodiment of this utility model, a motor is fixedly installed on the inner wall of the right side of the placement slot, and the output shaft of the motor is fixedly installed on the right side of the right clamping plate.

[0013] As a preferred embodiment of this utility model, a first rubber pad is fixedly installed on the left side of the right clamping plate, and a second rubber pad is fixedly installed on the right side of the left clamping plate. The left side of the first rubber pad and the right side of the second rubber pad are in contact with the left and right ends of the cylindrical steel shell of the lithium battery, respectively. Beneficial effects

[0014] 1. By placing the cylindrical steel shell of the lithium battery inside the placement slot, and then positioning and fixing the cylindrical steel shell of the lithium battery through the stabilizing component, after the cylindrical steel shell of the lithium battery is fixed, the two electric push rods are activated to drive the mounting tube, digital display vernier caliper, second screw, two connecting rods and arc-shaped pressure plate to move down. At this time, the arc-shaped pressure plate can press and fix the top of the cylindrical steel shell of the lithium battery. At this time, the fixed measuring end and the movable measuring end of the bottom of the digital display vernier caliper can contact the left side and the top of the cylindrical steel shell of the lithium battery, respectively. Then, by moving the movable measuring end of the digital display vernier caliper to the left, the end height of the cylindrical steel shell of the lithium battery can be measured.

[0015] 2. By rotating the first screw and engaging the threaded connection between the first screw and the base, the left clamping plate can be moved to the right and pressed against the right end of the lithium battery cylindrical steel shell, thereby achieving the installation and fixation of the lithium battery cylindrical steel shell and improving the stability of the lithium battery cylindrical steel shell during measurement. Here, by starting the motor, the right clamping plate, the lithium battery cylindrical steel shell and the left clamping plate can be rotated, enabling the digital display vernier caliper to perform multi-position measurement operations on the end height of the lithium battery cylindrical steel shell;

[0016] This invention achieves stable fixation of the cylindrical steel shell of the lithium battery through a simple structure, and enables rapid and accurate measurement of the end height of the cylindrical steel shell. Furthermore, it allows for rotation of the fixed cylindrical steel shell, facilitating multi-position measurement of the end height of the cylindrical steel shell, making it highly practical.
