Description

Technical Field

[0001] This utility model relates to a detection device, and more particularly to a high-speed detection device for large cylindrical batteries. Background Technology

[0002] In the automated production of large cylindrical lithium-ion batteries, especially those with a diameter of 46mm, precise measurement of key battery dimensions is crucial. These dimensions primarily include the height of the casing step (shoulder height), the overall battery height, and the height of the electrode terminals (posts). Accurate dimensional control is a critical process for ensuring the final assembly precision, safety, and performance consistency of the battery. With the increasing demands for battery energy density and power in applications such as new energy vehicles, the production scale and automation requirements for large cylindrical batteries are rising due to their structural advantages and performance potential.

[0003] To match the overall pace of high-speed production lines and address the insufficient testing capacity of individual testing equipment, manufacturers have had to increase the number of testing stations. This not only significantly increases equipment procurement costs but also substantially raises the production line's footprint, energy consumption, and the complexity and cost of subsequent maintenance.

[0004] Therefore, there is an urgent need to develop a high-speed, high-precision dimensional inspection device. Utility Model Content

[0033] The principles and features of this utility model are described below with reference to the embodiments; the examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] Figure 4 A large cylindrical battery is shown. When testing this large cylindrical battery, it is generally necessary to measure the shoulder height H1, the terminal height H2, and the total battery height H = H1 + H2.

[0035] A high-speed testing device for a large cylindrical battery includes a bracket 100, a first platform 200, a second platform 300, and a lifting mechanism 400. The first platform 200 and the second platform 300 are located on opposite sides of the bracket 100, and the lifting mechanism 400 is located below the bracket 100.

[0036] The bracket 100 includes a first plate 102 and a second plate 103, which have the same structure and are arranged in parallel at intervals. The upper surfaces of the first plate 102 and the second plate 103 are provided with an array of slots 101, which are V-shaped grooves to facilitate the support of large cylindrical batteries.

[0037] A first guide rail 203 is connected to the upper surface of the first platform 200, and a first slider 201 is slidably disposed above the first platform 200, with the first slider 201 slidably connected to the first guide rail 203. In this embodiment, four first sliders 201 are provided, enabling simultaneous detection of four large cylindrical batteries. The four guide rails 203 are arranged side by side, with one first slider 201 connected to each guide rail 203. A push plate 204 is provided on the first platform 200, located at the end of the first guide rail 203 away from the bracket 100. The push plate 204 can slide relative to the first platform 200, and is driven forward or backward by a cylinder. A spring rod 205 connects the push plate 204 and the first slider 201. The spring rod 205 includes a rod body 2051 and a spring 2052. One end of the rod body 2051 is screwed to the first slider 201, and the other end of the rod body 2051 passes through the push plate 204 and is connected to an enlarged portion 2053. The rod body 2051 and the push plate 204 form a sliding connection. The spring 2052 is sleeved on the rod body 2051 and is positioned between the first slider 201 and the push plate 204. A first limiting block 207 is provided on the side of the first slider 201 facing the bracket 100. The first limiting block 207 is used to limit the negative terminal of the large cylindrical battery. When the cylinder drives the push plate 204 to move towards the bracket 100, the push plate 204 compresses the spring 2052, and the spring 2052 pushes the first slider 201 to move towards the bracket 100, so that the first limiting block 207 contacts the negative terminal of the large cylindrical battery, forming a limit. When the cylinder drives the push plate 204 to move away from the bracket 100, the first slider 201 can be moved by the rod 2051 due to the design of the expanded part 2053. A first fixed plate 206 is connected to the first platform 200, and an array of first sensors 202 is disposed on the first fixed plate 206. The first fixed plate 206 spans above the spring rod 205. The number of first sensors 202 is the same as the number of large cylindrical batteries to be tested, and they correspond one-to-one.

[0038] The second platform 300 is connected to the second guide rail 303. The second slider 301 is positioned above the second platform 300 and is slidably connected to the second guide rail 303. A cylinder is connected to one side of the second slider 301, which is used to push the second slider 301 to slide. A second fixing plate 304 is connected to the second platform 300, spanning across the second platform 300. An array of second sensors 302 is connected to the second fixing plate 304. The number of second sensors 302 is the same as the number of large cylindrical batteries to be tested, and they correspond one-to-one. A limit plate 305 is connected to the second platform 300, and a limit rod 306 is connected to the second slider 301. The limit rod 306 is positioned on one side of the limit plate 305. The limit plate 305 is used to limit the maximum distance that the second slider 301 slides towards the bracket 100. A second limiting block 307 is connected to the side of the second slider 301 facing the bracket 100, and the second limiting block 307 is in contact with the positive terminal of the large cylindrical battery.

[0039] The lifting mechanism 400 includes a drive mechanism 401 and a bracket 402. The drive mechanism 401 drives the bracket 402 to move laterally or longitudinally. The bracket 402 is disposed between the first plate 102 and the second plate 103, and the bracket 402 also has the same number of V-grooves as the tray 101. The drive mechanism 401 includes a third guide rail 403 and a lifting cylinder 404. The lifting cylinder 404 moves laterally on the third guide rail 403 and drives the bracket 402 to move up and down. The lifting mechanism 400 is used to place a large cylindrical battery onto the bracket 100.

[0040] When measuring the large cylindrical battery, the lifting cylinder 404 first drives the bracket 402 to rise above the support 100; then the lifting cylinder 404 drives the bracket 402 to move laterally so that the large cylindrical battery is above the slot 101; the lifting cylinder 404 drives the bracket 402 to descend and place the large cylindrical battery into the slot 101; the second slider 301 is driven until the limiting rod 306 abuts against the limiting plate 305; the first slider 201 is driven to fix the large cylindrical battery between the first limiting block 207 and the second limiting block 307; finally, the first sensor 202 and the second sensor 302 are activated to measure the dimensions of the large cylindrical battery. The first sensor 202 is used to measure the shoulder height H1 of the large cylindrical battery, and the second sensor 302 is used to measure the terminal height H2 of the large cylindrical battery.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
