Technical Field
[0001] This utility model relates to the technical field of BMS board testing devices, specifically a BMS board testing device. Background Technology
[0002] Battery Management System (BMS), commonly known as a battery nanny or battery manager, is mainly used for intelligent management and maintenance of each battery cell, preventing overcharging and over-discharging, extending battery life, and monitoring battery status. According to existing technology, such as the BMS protection board testing device disclosed in Chinese patent document CN220252113U, the BMS board is placed on the upper end of the clamping seat, with the front end of the BMS board and the limiting strip in contact. Rotating the knob drives the worm gear to rotate, which in turn drives the worm wheel. Simultaneously, the lead screws on both sides of the worm wheel rotate, causing the sliders to move simultaneously, thus bringing the clamping strips closer together and fixing the left and right sides of the BMS board, achieving clamping of the BMS board.
[0003] According to its publicly available technical solutions, in existing technologies, qualified and defective products are usually sorted manually after testing. This may lead to worker fatigue, which may result in incomplete separation of finished and defective products, increasing the rate of defective products leaving the factory. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figures 1 to 3 This utility model provides the following technical solution: a BMS board testing device, including a testing device body, the testing device body including a fixed frame 1, a pressure plate 2 and a rotating mechanism 5, the fixed frame 1 is connected to a fixed rod 9, the fixed rod 9 passes through the pressure plate 2 and is connected to a housing 10, the pressure plate 2 is connected to a sleeve 3, the sleeve 3 is installed on the fixed rod 9, a test probe 4 is installed on the pressure plate 2, an electric lifting rod 8 is installed at the bottom of the fixed frame 1, the electric lifting rod 8 is connected to the pressure plate 2, a placement groove 6 is provided at the top of the housing 10, a rotating mechanism 5 is provided below the placement groove 6, and discharge ports 7 are provided on both sides of the housing 10. In use, the electric lifting rod 8 is activated, causing the electric lifting rod 8 to push the pressure plate 2 downward, so that the test probe 4 on the pressure plate 2 contacts the test interface on the BMS board. After the test is completed, the pressure plate 2 is lifted upward, so that the test probe 4 is separated from the BMS board.
[0022] In this embodiment, the rotating mechanism 5 includes a motor 15 and a rotating plate 14. The motor 15 is connected to a rotating shaft 13, and the rotating shaft 13 is connected to the rotating plate 14. The motor 15 is installed at the front end of the housing 10. The size of the rotating plate 14 is smaller than that of the placement slot 6. After the BMS board test is completed, if the product is qualified, the motor 15 is then started, causing the motor 15 to drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the rotating plate 14 to rotate, causing the rotating plate 14 to rotate to one side. If the product is unqualified, the motor 15 is rotated in the opposite direction, causing the unqualified product to fall to the other side.
[0023] In this embodiment, a discharge plate 11 is provided inside the housing 10. One end of the discharge plate 11 is connected to a hinge seat 16, which is connected to the bottom of the housing 10. The discharge plate 11 is connected to a spring 12, which is also connected to the bottom of the housing 10. When the rotating plate 14 rotates, one end moves downward and contacts the discharge plate 11, causing the BMS to fall onto the discharge plate 11 and slide out of the discharge port 7. The discharge plate 11 can rotate through the hinge seat 16 to avoid obstructing the rotation of the rotating plate 14. At the same time, the spring 12 connected to it can, on the one hand, allow the discharge plate 11 to return to its original position when it separates from the rotating plate 14, and on the other hand, the spring 12 can play a shock absorption role, reducing the impact when the BMS board falls.
[0024] Working principle: When in use, place the BMS board into the placement slot 6, start the electric lifting rod 8, which pushes the pressure plate 2 downward, so that the test probe 4 on the pressure plate 2 contacts the test interface on the BMS board to test the function of the BMS. After the test is completed, lift the pressure plate 2 upward to separate the test probe 4 from the BMS board. If the product is qualified, start the motor 15 to rotate the rotating plate 14 to one side and slide the BMS board out from the discharge port 7 on one side of the box 10. If the product is unqualified, rotate the rotating plate 13 to the other side and slide it out from the discharge port 7 on the other side.
[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
