Technical Field

[0001] This utility model relates to the field of BMS testing technology, and specifically to a BMS rapid testing workbench. Background Technology

[0002] Battery Management System (BMS) is now widely used in energy storage, electric vehicles and smart grids to ensure the safe and long-term operation of batteries, monitor the battery's operating status in real time and manage charging and discharging.

[0003] Due to the sealed environment and stringent reliability requirements of BMS products, battery management systems undergo thorough offline functional testing before installation and use. Currently, common testing fixtures and program updates all require the plugging and unplugging of wiring harnesses, sometimes even necessitating multiple manual plugging and unplugging operations by operators, increasing manufacturing costs and contributing to product quality instability. Utility Model Content

[0004] To overcome the aforementioned objectives, this utility model provides a rapid testing workbench for BMS (Body Management System). This workbench, through a frame and mounting platform, provides a stable operating surface. A pneumatic power mechanism provides pneumatic drive power, connecting a vertical pressing mechanism and a horizontal moving mechanism. Multiple positioning mechanisms are used to position and place the BMS, enabling multiple batch measurements. The vertical pressing mechanism provides stable pressure on the BMS, ensuring its fixation. A horizontal moving mechanism and an alignment detection mechanism drive the alignment detection mechanism to quickly align and connect the BMS located on the positioning mechanism, achieving accurate and rapid testing, improving work efficiency, and avoiding human error during insertion and removal. A controller is electrically connected to the pneumatic power mechanism, positioning mechanism, vertical pressing mechanism, alignment detection mechanism, and horizontal moving mechanism, enabling efficient and rapid activation of the pneumatic power mechanism. After the BMS is positioned, the vertical pressing mechanism presses down on the BMS to fix it. Once the BMS is firmly fixed, the horizontal moving mechanism drives the alignment detection mechanism to align and test the BMS, thus achieving rapid automatic testing. Simultaneously, test data is recorded and stored for convenient production statistics.

[0005] To achieve the above objectives, this utility model provides a BMS rapid testing workbench, the workbench comprising: A frame, the top of which is provided with an installation platform; A pneumatic power mechanism, wherein the pneumatic power mechanism is disposed inside the frame; Multiple positioning mechanisms are provided, which are located on the top of the installation platform and are used to mount the BMS.

[0016] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

Figure 3 The diagram shown is a structural schematic of the alignment detection mechanism of a BMS rapid detection workbench according to one embodiment of the present invention. Figure 4 The diagram shown is an exploded view of a BMS rapid inspection workbench according to one embodiment of the present invention. Figure 1The workbench may include a frame 1, a pneumatic power mechanism 2, multiple positioning mechanisms 3, multiple vertical pressing mechanisms 4, multiple alignment detection mechanisms 5, multiple horizontal moving mechanisms 6, and a controller (not shown in the figure). Specifically, a mounting platform is provided on the top of the frame 1, the pneumatic power mechanism 2 is located inside the frame 1, the positioning mechanism 3 is located on the top of the mounting platform, and is used to mount the BMS; multiple vertical pressing mechanisms 4, corresponding one-to-one with the positioning mechanisms 3, are located above the positioning mechanisms 3 and are pneumatically connected to the pneumatic power mechanism 2, and are used to press down the BMS; multiple alignment detection mechanisms 5, corresponding one-to-one with the positioning mechanisms 3, are located on one side of the positioning mechanisms 3; multiple horizontal moving mechanisms 6, corresponding one-to-one with the alignment detection mechanisms 5, are located below the alignment detection mechanisms 5 and are pneumatically connected to the pneumatic power mechanism 2, and are used to drive the alignment detection mechanisms 5 to connect to the BMS; the controller is electrically connected to the pneumatic power mechanism 2, the positioning mechanism 3, the vertical pressing mechanism 4, the alignment detection mechanism 5, and the horizontal moving mechanism 6, and realizes the control of the operation of the pneumatic power mechanism 2 to drive the operation of the other mechanisms. After the operator places the BMS to be tested onto the positioning mechanism 3, they press the power switch with both hands. The controller receives a signal from the proximity switch sensor that the BMS has been positioned. The controller then controls the vertical cylinder 41 via the pneumatic power mechanism 2 to drive the flexible insulating pressing block 43 downward. During the downward pressing process, the flexible insulating pressing block 43 presses the BMS along the vertical guide rail 42. Before reaching the designated position, the hydraulic buffer works to reduce the impact and prevent damage to the BMS shell. After receiving the signal that the vertical pressing mechanism 4 has completed pressing, the controller drives the horizontal cylinder 62 to operate. The horizontal cylinder 62 drives the horizontal slider 63 to move the alignment detection mechanism 5 towards the BMS to be tested along the horizontal slide rail. When it reaches the designated position, the alignment detection mechanism 5 inserts into the BMS to be tested, and the matching test equipment begins functional testing, achieving precise insertion testing.

[0018] Through the above technical solution, the workbench provides a stable operating surface by setting up a frame and mounting platform. A pneumatic power mechanism provides pneumatic drive power, driving the vertical pressing mechanism and horizontal moving mechanism. Multiple positioning mechanisms are set up for positioning and placing the BMS (Battery Management System) to achieve multiple batch measurements. The vertical pressing mechanism provides stable pressure on the BMS, ensuring its fixation. A horizontal moving mechanism and an alignment detection mechanism are set up. The horizontal moving mechanism drives the alignment detection mechanism to quickly align and connect to the BMS located on the positioning mechanism, achieving accurate and rapid testing, improving work efficiency, and avoiding human error during insertion and removal. The controller is electrically connected to the pneumatic power mechanism, positioning mechanism, vertical pressing mechanism, alignment detection mechanism, and horizontal moving mechanism, enabling reasonable and rapid activation of the pneumatic power mechanism. After the BMS is positioned and placed, the vertical pressing mechanism is driven to press down on the BMS, fixing it in place. Once the BMS is firmly fixed, the horizontal moving mechanism drives the alignment detection mechanism to align and test the BMS, thus quickly achieving automatic testing. Simultaneously, test data is recorded and stored for convenient production statistics.

[0019] exist Figure 1 In order to control the pneumatic power mechanism 2, in one embodiment of this utility model, the pneumatic power mechanism 2 includes a pneumatic drive assembly (not shown in the figure) and an operation switch 21.

The proximity switch sensor is set on the positioning mechanism 3. After detecting that the BMS is in place, the proximity switch sensor controls the operation switch 21 to close, thereby protecting the operator, avoiding operator misoperation, and ensuring safe production.
