Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a battery cell testing device. Background Technology

[0002] In the field of battery cell testing, with the rapid development of electronic technology, various electronic devices are placing increasingly stringent requirements on the performance and quality of battery cells. OVC (Over Charge Voltage) testing, as a crucial step in battery cell testing, plays a vital role in ensuring the safety and stability of battery cells.

[0003] Most battery cell testing equipment on the market currently uses a fixed probe design. This fixed probe design has extremely poor versatility when dealing with battery cells of different sizes and electrode positions. It often requires specialized design and manufacturing for specific battery cell specifications. Once the battery cell specification is changed, the equipment becomes difficult to adapt, leading to testing difficulties. Furthermore, fixed probes cannot accommodate diverse testing needs, making it difficult to accurately obtain comprehensive testing data, severely impacting the accuracy of battery cell quality assessment. In addition, manually adjusting the probe position during testing is not only cumbersome and time-consuming, greatly reducing testing efficiency, but also prone to inaccurate probe position adjustments due to human factors, resulting in human error. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the objective is to provide a battery cell testing device.

[0005] Technical Solution: A battery cell testing device includes a frame, a first transmission line, a second transmission line, a control cabinet, a first mounting frame, a mounting plate, a detector, a second mounting frame, a first transmission component, an electric cylinder, a guide frame, a second transmission component, a slide, and a testing probe. Two first transmission lines and two second transmission lines are respectively located on the left and right sides of the upper part of the frame. The first and second transmission lines are laid in the same direction, and a turning mechanism is provided in the area between the first and second transmission lines. Material on the first transmission line is conveyed to the right into the turning mechanism. After the direction of the material is adjusted by the turning mechanism, the turning mechanism transfers the material to the right. Inside transmission line 2, both transmission line 1 and transmission line 2 have control cabinets at their bottoms. Transmission line 1 has a fixed frame 1, and the upper part of the fixed frame 1 has a mounting plate. The mounting plate has a detector, and the detection end of the detector faces the side of transmission line 1. Transmission line 2 has a fixed frame 2, and the fixed frame 2 has a transmission component 1. The transmission component 1 is vertically equipped with an electric cylinder. The transmission component 1 drives the electric cylinder to move back and forth. The drive rod of the electric cylinder is equipped with a guide frame. The lower part of the guide frame is symmetrically equipped with transmission components 2. The transmission components 2 are equipped with slides, and the slides are equipped with detection probes.

[0006] Furthermore, the steering mechanism includes a rotating seat, a support seat, and a transmission line three. Two rotating seats are provided on the frame, and the two rotating seats are distributed between the transmission lines one and two on the front and rear sides at a distance. Each rotating seat is provided with a support seat on top, and each support seat is provided with a transmission line three. The rotating seats drive the support seats to rotate 180 degrees.

[0007] Furthermore, it also includes an integrated testing module, which is installed on each mounting plate.

[0008] Furthermore, it also includes a support frame, transmission line four, transplanting robot and gripper. There are two support frames on the right side of the frame, and multiple transmission lines four are arranged at intervals on the support frames. There are two transplanting robots on the right side of the frame through the mounting bracket. The transplanting robot consists of a drive component and a lifting component installed on the drive device. When the lifting component moves back and forth under the drive of the drive component, and each lifting component is equipped with a gripper, when the gripper moves, it will pass through the space above the right side of transmission line four and the right side of transmission line two on the same side.

[0009] Furthermore, it also includes cylinders and limit blocks. Cylinders are provided on the right side of transmission line one and the left side of transmission line two. Limit blocks are provided on the movable rods of the cylinders. The limit blocks move back and forth as the movable cylinder extends and retracts.

[0010] Compared with the prior art, the present invention has the following advantages: 1. The present invention can perform cell testing by setting an adjustable probe position, which can adapt to cells of different sizes and electrode positions, and can also be compatible with diverse testing needs, accurately acquiring testing data; at the same time, it greatly reduces manual adjustment, and achieves automatic and accurate probe adjustment with the help of advanced devices, shortening adjustment time, improving testing efficiency, and reducing human error and labor intensity.

[0011] 2. This utility model identifies the polarity of the battery cell by setting a visual inspection unit before the battery cell is inspected. When the direction of the electrode tab is detected to be inconsistent with the preset requirements, the battery cell is automatically flipped 180° by the rotating seat of the steering mechanism to ensure that all battery cells enter the subsequent inspection station with the same polarity.

[0012] 3. This utility model sets up a sorting station consisting of a transplanting robot and multiple transmission lines. The battery cells are automatically classified according to the resistance value after testing. After the testing mechanism completes the electrical performance test, the transplanting robot can accurately grab the battery cells and transfer them to different transmission lines according to the preset resistance threshold, realizing fully automatic sorting operation and reducing the error rate of manual sorting.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] A battery cell testing device, such as Figure 1-5 As shown, it includes a frame 1, a transmission line 1 2, a transmission line 2 3, a control cabinet 31, a mounting frame 1 4, a mounting plate 41, a detector 42, a mounting frame 2 5, a transmission component 1 51, an electric cylinder 52, a guide frame 53, a transmission component 2 531, a slide 54, and a detection probe 55. Two transmission lines 1 (2) and two transmission lines 2 (3) are respectively located on the left and right sides of the upper part of the frame 1. The transmission lines 1 (2) and 2 (3) are laid in the same direction, and a turning mechanism is provided in the area between the transmission lines 1 (2) and 2 (3). The turning mechanism includes a rotating seat 32, a support seat 33, and a transmission line 34. The frame 1 has two rotating seats 32, which are distributed at intervals between the transmission lines 1 (2) and 2 (3) on the front and rear sides. Each rotating seat 32 has a support seat 33 on its top, and each support seat 33 has a transmission line 34. The rotating seat 32 can drive the support seat 33 to rotate 180 degrees. The material of the transmission line 1 (2) will be transferred to the right into the turning mechanism. When the material reaches the transmission line 3 (34), the rotating seat 32 starts, driving the support seat 33 and the material on the transmission line 3 (34) to rotate 180 degrees, thereby adjusting the direction of the material. Then the turning mechanism will transfer the material to the right into the transmission line 2 (3). Through this turning design, the material can be smoothly transferred between different transmission lines, improving the flexibility and efficiency of material transfer.

[0022] Both transmission line 2 and transmission line 3 are equipped with control cabinets 31 at their bottom. Control cabinets 31 serve as the control center for the entire equipment, precisely controlling the operating parameters and timing of transmission lines 2, 3, and subsequent components to ensure coordinated operation of all parts of the equipment. Each transmission line 2 is equipped with a mounting bracket 4, and each mounting bracket 4 has a mounting plate 41 on its upper part. Each mounting plate 41 is equipped with a detector 42, with the detection end of the detector 42 facing one side of transmission line 2. When the battery cell is transmitted on transmission line 2, the detector 42 can perform preliminary testing on the battery cell, such as detecting its appearance and dimensions, preparing for more precise subsequent testing.

[0023] Each transmission line 2 3 is equipped with a fixed frame 2 5, and each fixed frame 2 5 is equipped with a transmission component 1 51. Each transmission component 1 51 is vertically equipped with an electric cylinder 52. The transmission component 1 51 can drive the electric cylinder 52 to move back and forth. Each electric cylinder 52 has a guide frame 53 on its drive rod. The lower part of the guide frame 53 is symmetrically equipped with a transmission component 2 531. Each transmission component 2 531 is equipped with a slide 54. Each slide 54 is equipped with a detection probe 55. During the testing process, transmission component 51 first drives the electric cylinder 52 to move back and forth, bringing the testing probe 55 to a suitable horizontal position. Then, the drive rod of the electric cylinder 52 extends and retracts, causing the guide frame 53, transmission component 531, and slide 54 to move up and down, thereby adjusting the vertical position of the testing probe 55. This allows the testing probe 55 to accurately contact the testing area of ​​the battery cell, achieving precise testing of the battery cell. This multi-degree-of-freedom adjustment method greatly improves the versatility and accuracy of the testing, adapting to the testing needs of battery cells of different sizes and electrode positions. At the same time, it reduces manual adjustment, improves testing efficiency, and reduces human error and labor intensity.

[0024] Example 2

[0025] Based on Example 1, such as Figure 1 and Figure 5 As shown, it also includes an integrated detection module 43. The integrated detection module 43 is installed on the mounting plate 41. The integrated detection module 43 works in conjunction with the detector 42 on the transmission line 2. The integrated detection module 43 performs multi-dimensional synchronous detection of the battery cell through multi-sensor fusion technology (such as optical sensors, temperature sensors, etc.), such as detecting parameters such as surface defects of the battery cell, electrode welding quality, and dimensional deviation. Its detection data complements the preliminary detection results of the detector 42, forming a more comprehensive battery cell quality assessment system, effectively improving detection accuracy and reliability.

[0026] like Figure 1As shown, it also includes a support frame 7, transmission lines 71, transplanting robots 72, and grippers 73. The right side of the frame 1 has two support frames 7, each with multiple transmission lines 71 arranged at intervals. These transmission lines 71 are parallel to and connected at their ends to transmission lines 3, and are used to temporarily store and classify the tested battery cells for output. The right side of the frame 1 has two transplanting robots 72 mounted on a mounting bracket. Each transplanting robot 72 consists of a drive component (such as a servo motor) and a drive unit. It consists of a lifting component (such as a linear slide rail) installed on the top. The lifting component moves back and forth in the horizontal direction under the drive of the drive component. Each lifting component is equipped with a gripper 73. The gripper 73 grips the battery cell by pneumatic or electric means. When the transfer robot 72 is running, the gripper 73 passes through the space above the right side of the fourth transmission line 71 and the right side of the second transmission line 3 on the same side, so as to accurately grab the battery cell that has been tested on the second transmission line 3 and transfer it to the designated position on the fourth transmission line 71, realizing the automated sorting and circulation of battery cells, reducing manual intervention, and significantly improving testing efficiency.

[0027] like Figure 2 and Figure 5 As shown, it also includes a cylinder 6 and a limiting block 61. Cylinders 6 are installed on the right side of transmission line 2 and the left side of transmission line 3. Limiting blocks 61 are installed on the movable rods of cylinders 6. The limiting blocks 61 move back and forth with the extension and retraction of the movable cylinder 6. When cylinder 6 drives the limiting block 61 to extend, the limiting block 61 enters the material transmission path between transmission line 2 and transmission line 3, blocking the battery cell and controlling its dwell time before the testing station, ensuring the completion of the testing actions of detector 42 and integrated testing module 43. When cylinder 6 drives the limiting block 61 to retract, the battery cell transmission resumes. Specifically, the limiting block 61 on transmission line 2 is located at the rear of the testing station, used to restrict subsequent battery cells from entering the testing area during the testing process, avoiding accumulation and interference with testing. The cylinder 6 on transmission line 3 is located at the front of the testing station, used to precisely limit the battery cell when it enters transmission line 3 after turning, ensuring stable contact between the testing probe 55 and the battery cell electrode. Through the coordinated action of cylinder 6 and limit block 61, the orderly feeding and precise positioning of the battery cells during the transmission process are achieved, which not only ensures the continuity of the detection process, but also avoids detection errors caused by battery cell position deviation.
