[0003] During the testing of battery cells, workers typically need to hold the cell to inspect its appearance before placing it into a battery cell performance testing device to test its voltage, capacity, and charge / discharge properties. Appearance and performance testing need to be conducted separately, increasing the workload of workers and reducing work efficiency. Therefore, an easy-to-use IQC battery cell testing device is designed to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an easy-to-use IQC cell testing device, which solves the problem of low testing efficiency in existing cell testing devices.

[0006] This utility model provides an easy-to-use IQC battery cell testing device, including a workbench, a battery cell performance tester, and an auxiliary testing device. The battery cell performance tester is fixedly installed on the right side of the upper surface of the workbench, and the auxiliary testing device is installed on the left side of the upper surface of the workbench.

[0007] The auxiliary testing device includes a track rod mounted on a workbench and a vertical plate fixed inside the track rod. A slider is slidably mounted on the track rod, and a gear is rotatably mounted on the slider via a pin. A negative spring is fixedly mounted at the center of the upper surface of the gear, and an arc-shaped plate is fixedly mounted on the upper surface of the gear. A metal contact plate is fixedly mounted at the center of the right side surface of the slider. A rack is fixedly mounted above the vertical plate. An inverted L-shaped bracket is fixedly mounted at the right end of the upper surface of the track rod. A positive spring is fixedly mounted at the bottom of the inner side of the inverted L-shaped bracket. A through slot is opened at the center of the lower part of the inverted L-shaped bracket, and a spring is fixedly mounted at the bottom of the through slot. A trapezoidal contact block is fixedly mounted at the bottom of the spring. The positive spring and the trapezoidal contact block are electrically connected to a cell performance tester via wires.

[0008] Preferably, the track rod is in the shape of an inverted convex character, and a groove matching the track rod is provided below the slider, and a gripper rod is fixedly provided at the outer end of the slider.

[0009] Preferably, the gear and the rack mesh with each other.

[0010] Preferably, the slider, gear, metal contact plate, and trapezoidal contact block are all made of copper material with good electrical conductivity.

[0011] Preferably, the inner diameter of the arc-shaped plate is not less than the diameter of the battery cell to be tested, and the outer opening width of the arc-shaped plate is less than the diameter of the battery cell to be tested.

[0012] Preferably, the metal contact plate matches the through slot, and when the slider slides to the rightmost side of the track rod, the metal contact plate passes through the through slot, and at this time the trapezoidal contact block is in close contact with the upper surface of the metal contact plate, and the spring is in a compressed state.

[0013] Preferably, the inner surface of the arc-shaped plate is provided with a plurality of mounting grooves, and a rubber roller is rotatably arranged inside the mounting groove.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. This utility model, by setting up an auxiliary detection device, first places the negative electrode of the battery cell into the arc-shaped plate when performing IQC inspection. The negative electrode spring of the battery cell is then placed inside the arc-shaped plate to position the battery cell. Then, the slider is moved to the right by grasping the gripper rod 401. The slider drives the gear to rotate along the rack, causing the negative electrode spring and the battery cell on the gear to rotate. This makes it convenient for the battery cell to align with the outer opening of the arc-shaped plate from different positions. The operator can easily observe whether there are any defects on the outer surface of the battery cell through the opening on the outer side of the arc-shaped plate 7, thus achieving the effect of battery cell appearance inspection.

[0016] 2. When the slider of this utility model slides to the right end of the track rod, the metal contact plate is inserted into the through groove, pushing the trapezoidal contact block upward. The spring is in a compressed state, and the spring force makes the trapezoidal contact block and the metal contact plate tightly connected. At this time, the positive electrode of the battery cell to be tested contacts the positive electrode spring, and the positive electrode spring is electrically connected to the battery cell performance tester. The negative electrode of the battery cell is electrically connected to the battery cell performance tester through the negative electrode spring, gear, slider, metal contact plate and trapezoidal contact block, so as to achieve the effect of battery cell performance testing. The appearance and performance testing of the battery cell can be continuously tested by the auxiliary testing device, increasing work efficiency.

[0017] 3. This utility model is equipped with an installation groove and rubber rollers. Multiple rubber rollers are provided on the inner surface of the arc plate. During the battery cell testing process, the battery cell is driven to rotate by gears. The battery cell contacts the rubber rollers. The rotation of the rubber rollers can reduce the friction between the battery cell and the arc plate, prevent the battery cell from being damaged by friction with the arc plate 7 during the testing process, and ensure the quality of the battery cell.

Detailed Implementation

[0026] Example:

[0027] like Figures 1-5 As shown, an embodiment of the present invention provides an easy-to-use IQC cell testing device, including a workbench 1, a cell performance tester 2, and an auxiliary testing device. The cell performance tester 2 is fixedly installed on the right side of the upper surface of the workbench 1, and the auxiliary testing device is installed on the left side of the upper surface of the workbench 1.

[0028] The auxiliary testing device includes a track rod 3 mounted on the workbench 1 and a vertical plate 9 fixed inside the track rod 3. A slider 4 is slidably mounted on the track rod 3. A gear 5 is rotatably mounted on the slider 4 via a pin. A negative spring 6 is fixedly mounted at the center of the upper surface of the gear 5. An arc-shaped plate 7 is fixedly mounted on the upper surface of the gear 5. A metal contact plate 8 is fixedly mounted at the center of the right side surface of the slider 4. A rack 10 is fixedly mounted above the vertical plate 9. An inverted L-shaped bracket 11 is fixedly mounted at the right end of the upper surface of the track rod 3. A positive spring 12 is fixedly mounted at the bottom of the inner side of the inverted L-shaped bracket 11. A through groove 1101 is opened at the center of the lower part of the inverted L-shaped bracket 11. A spring 13 is fixedly mounted at the bottom of the through groove 1101. A trapezoidal contact block 14 is fixedly mounted at the bottom of the spring 13. The positive spring 12 and the trapezoidal contact block 14 are electrically connected to the cell performance tester 2 via wires.

[0029] By setting up an auxiliary detection device, when performing IQC inspection on the battery cell, the negative terminal of the battery cell is first aligned with the negative terminal spring 6 and placed inside the arc plate 7. The arc plate 7 is used to position the battery cell. Then, the slider 4 is moved to the right by grasping the gripper rod 401. The slider 4 drives the gear 5 to rotate along the rack 10, so that the negative terminal spring 6 and the battery cell on the gear 5 rotate. This makes it convenient for the battery cell to be aligned with the outer opening of the arc plate 7 from different positions. The staff can easily observe whether there are any defects on the outer surface of the battery cell through the outer opening of the arc plate 7, thus achieving the effect of battery cell appearance inspection.

[0030] When slider 4 slides to the right end of track rod 3, metal contact plate 8 is inserted into through groove 1101, pushing trapezoidal contact block 14 upward. Spring 13 is in a compressed state, and the elastic force of spring 13 makes trapezoidal contact block 14 tightly connected to metal contact plate 8. At this time, the positive electrode of the battery cell to be tested contacts the positive electrode spring 12. The positive electrode spring 12 is electrically connected to battery cell performance tester 2. The negative electrode of the battery cell is electrically connected to battery cell performance tester 2 through negative electrode spring 6, gear 5, slider 4, metal contact plate 8 and trapezoidal contact block 14, so as to achieve the effect of battery cell performance testing. The appearance and performance testing of the battery cell can be continuously tested by auxiliary testing device, increasing work efficiency.

[0031] It should be noted that the cell performance tester 2 is a common testing device on the market, which can test the voltage, capacity, and charging and discharging status of the cell.

[0032] In this embodiment, the track rod 3 is in the shape of an inverted convex character, and the slider 4 has a groove at the bottom that matches the track rod. A gripper rod 401 is fixedly installed at the outer end of the slider 4 to ensure the stability of the slider 4 sliding on the track rod 3.

[0033] In this embodiment, gear 5 meshes with rack 10, so that gear 5 rotates along rack 10 when slider moves.

[0034] In this embodiment, the slider 4, gear 5, metal contact plate 8, and trapezoidal contact block 14 are all made of copper with good conductivity, ensuring the conductivity of the slider 4, gear 5, metal contact plate 8, and trapezoidal contact block 14.

[0035] In this embodiment, the inner diameter of the arc plate 7 is not less than the diameter of the battery cell to be tested, and the width of the outer opening of the arc plate 7 is less than the diameter of the battery cell to be tested, which facilitates the observation of the outer surface of the battery cell while preventing the battery cell from falling out of the opening of the arc plate 7.

[0036] In this embodiment, the metal contact plate 8 is matched with the through groove 1101, and when the slider 4 slides to the rightmost side of the track rod 3, the metal contact plate 8 passes through the through groove 1101, and at this time the trapezoidal contact block 14 is in close contact with the upper surface of the metal contact plate 8, and the spring 13 is in a compressed state to ensure close contact between the metal contact plate 8 and the trapezoidal contact block 14.

[0037] In this embodiment, a plurality of mounting grooves 701 are provided on the inner surface of the arc plate 7, and a rubber roller 702 is rotatably arranged inside the mounting groove 701.

[0038] By providing an installation groove 701 and rubber rollers 702, multiple rubber rollers 702 are provided on the inner surface of the arc plate 7. During the battery cell testing process, the battery cell is driven to rotate by the gear 5. The battery cell contacts the rubber rollers 702. The rotation of the rubber rollers 702 can reduce the friction between the battery cell and the arc plate 7, prevent the battery cell from being damaged by friction with the arc plate 7 during the testing process, and ensure the quality of the battery cell.

[0039] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
