Description

Technical Field

[0001] The utility model relates to the field of lithium ion batteries, and more specifically, to a lithium ion battery core detection device. Background Art

[0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ is embedded and deintercalated back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode and embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharging.

[0003] When conducting contact tests on existing batteries, most of them are placed on a test bench for testing. During the test, they are clamped and fixed by a fixture, and then the test is completed by a test probe in cooperation with a tester. The test probe is usually a movable structure that can be adjusted for use. For example, Chinese utility model application No. 202023234933.7 proposes a short-circuit detection device for lithium-ion battery cells. When the device is in use, the pressure plate fixes the battery cell on the support table under the action of the rebound force of the support spring, thereby achieving clamping and fixing of the battery cell, and then the control switch controls the extension of the telescopic end of the electric telescopic rod to move the mounting seat downward, and the mounting seat drives the test probe to move downward, thereby achieving adjustment of the height of the test probe, and the rotating block is rotated to rotate the rotating rod, and the rotation of the rotating rod drives the gear 10 to rotate, and the rotation of the gear drives the mounting block to slide horizontally, and the sliding of the mounting block can achieve adjustment of the horizontal direction of the test probe 13; the problems existing in the use of the device are:

[0004] During the battery cell testing process, the positions of the tabs are different for different battery cell specifications and models. Some tabs are set on the side of the battery cell, some are set on the top or bottom of the battery cell, and some are set at an angle at the edge of the battery cell. Therefore, when the detection probe structure in the above-mentioned detection device is used to detect it, only the battery cells with the tabs set at the upper and lower positions can be detected, and the battery cell tabs at different positions cannot be flexibly adjusted for detection, and the detection range needs to be improved. At the same time, the clamp structure is in hard contact with the surface of the battery cell during the clamping operation, which can easily cause indentations or damage to the surface of the battery cell, affecting the detection.

[0005] Therefore, the utility model provides a lithium ion battery cell detection device. Utility Model Content

A guide plate 8 is fixedly connected to the surface of the vertical plate 1. A first guide groove 11 is formed on the surface of the guide plate 8. An adjustment component 12 is embedded in the first guide groove 11. The adjustment component 12 is fixedly connected to the detection probe structure 7 at the same time. A display screen 9 and a pump body mechanism 10 are fixedly connected to the surface of the vertical plate 1 at the same time. The pump body mechanism 10 is arranged in a matching manner with the first limiting structure 5 at the same time.

[0033] In the embodiment of the present utility model, two groups of the first limiting structures 5 are arranged adjacent to each other, including a first sliding seat 17 and a limiting pressing plate 18 which are fixedly connected, and further including a limiting air cushion 19 fixedly connected to the limiting pressing plate 18. The second limiting structure 6 is located between the two groups of the first limiting structures 5. The second limiting structure 6 includes a second sliding seat 20 and a connecting plate 21 which are fixedly connected, and further includes a third guiding groove 22 on the surface of the connecting plate 21. The side plate structure 3 includes a side plate main body 13 arranged in an "L" shape and a second guiding groove 14 opened in a rectangular shape on its surface. The detection probe structure 7 includes a probe main body 15 and a positioning disk 16 which are fixedly connected. Detection lines are simultaneously connected to both ends of the probe main body 15. One end of the detection line is fixedly connected to the adjusting assembly 12, and the other end of the detection line is connected to an external detector. The guiding plate 8 is arranged horizontally as a whole, and the first guiding groove 11 is opened horizontally along the surface of the guiding plate 8. The adjusting assembly 12 is composed of two movable disks fixedly connected by a shaft body. The two movable disks are respectively located in the front and back positions of the first guiding groove 11. The shaft body passes through the first guiding groove 11, and the movable disk in the front position of the first guiding groove 11 is fixedly connected to the detection line connected to the probe main body 15. By means of the cooperation between the guiding plate 8 and the first guiding groove 11 on its surface, the adjusting assembly 12 can be conveniently adjusted to slide horizontally along it, and by means of the adjusting assembly 12, the whole detection probe structure 7 can be driven to slide and adjust on the surface of the vertical plate 1.

[0034] A communicating pipe is arranged outside the pump body mechanism 10, and the communicating pipe is also communicated with the limiting air cushion 19. When adjusting the position of the detection probe structure 7, the user slides the whole adjusting assembly 12 along the guiding plate 8, and the adjusting assembly 12 drives the probe main body 15 to move and adjust in cooperation with the detection line connected to the probe main body 15.

[0035] During detection, after adjusting the overall position of the detection probe structure 7, the probe main body 15 therein is made to contact the position of the tab of the battery cell, and the outer end of the probe main body 15 is connected to an external detector by a line, so as to facilitate the completion of the detection.

[0036] The back corner position of the side plate main body 13 is connected to both ends of the detection table 2 by connecting screws. The second guiding groove 14 is opened through on the surface of the side plate main body 13, and a magnetic attraction layer is additionally arranged on both side edge positions of the second guiding groove 14.

[0037] During the detection process, the user first adjusts the position of the adjustment component 12 so that the probe body 15 passes through the second guiding groove 14 on the surface of the side plate body 13 and aligns with the tab at the side position of the battery cell. At this time, the positioning disk 16 is adsorbed on the outer side of the second guiding groove 14 under the action of the magnetic adsorption layer, realizing the fixation of the probe body 15 at the position of the second guiding groove 14.

[0038] The first sliding seat 17 is located at the back positions of both ends of the limiting pressure plate 18 and is simultaneously slidably connected to the guide rail 4.

By means of the first sliding seat 17, the position of the entire first limiting structure 5 is slidably adjusted along the guide rail 4, and the battery cell is fixed by the cooperation of the limiting pressure plate 18 and the limiting air cushion 19.

[0039] The battery cell is placed on the surface of the detection table 2. When fixing it, the user slides the first sliding seat 17 and adjusts the distance between the two groups of first limiting structures 5 according to the size of the battery cell, so that both ends of the battery cell are located below the limiting pressure plate 18. Then, the limiting air cushion 19 is inflated through the pump body mechanism 10, and the inflated limiting air cushion 19 presses and fixes the battery cell. The air cushion type fixing method can effectively avoid hard contact with the surface of the battery cell, achieving the fixation of the battery cell while enhancing the fixing protection of the battery cell.

[0040] The second sliding seat 20 is located at the back positions of both ends of the connecting plate 21 and is simultaneously slidably connected to the guide rail 4. The connecting plate 21 is arranged as a rectangular plate.

By means of the second sliding seat 20, the position of the entire second limiting structure 6 is slidably adjusted along the guide rail 4, and the detection probe structure 7 is limited and fixed through the third guiding groove 22.

[0041] During the detection, the user slides the position of the second limiting structure 6 so that the third guiding groove 22 aims at the tab position on the surface of the battery cell. Then, the user makes the detection probe 15 pass through the third guiding groove 22 and contact the tab position on the surface of the battery cell. At this time, the positioning disk 16 in the detection probe structure 7 is adsorbed and fixed at the position of the third guiding groove 22 under the action of the magnetic adsorption layer, ensuring the contact stability between the detection probe 15 and the tab position.
