Description

Technical Field

[0001] This utility model relates to the field of automotive data acquisition, and in particular to an intelligent data acquisition device used in automotive production lines. Background Technology

[0002] In automotive manufacturing production lines, intelligent data acquisition terminals integrating industrial robotic arms are commonly used to automate the acquisition and writing of vehicle controller data. Existing solutions typically involve directly mounting the vehicle diagnostic interface (OBD) connector to the end effector of the robotic arm using a rigid bracket. The robotic arm moves according to a pre-programmed path to the preset OBD interface position within the vehicle's cockpit, undergoes assisted calibration using a vision positioning system, and ultimately completes the automated connection between the diagnostic connector and the vehicle interface. This process aims to replace traditional manual operation, achieving a high degree of automation in the end-of-line (EOL) inspection, and establishing a physical connection for subsequent data acquisition and configuration writing.

[0003] However, the aforementioned existing technical solutions have significant drawbacks. First, their compatibility and flexibility are extremely poor. The position and angle of the OBD interface in the cabin vary greatly among different vehicle models. Adjusting the robotic arm's operating path for each new model requires complex re-teaching and reprogramming, which is labor-intensive, error-prone, and difficult to adapt to the needs of modern mixed-line production. Second, this rigid connection method places extremely stringent requirements on the absolute positioning accuracy of the robotic arm. Even slight deviations can easily lead to collisions between the robotic arm and the vehicle interior or the interface itself, resulting in damage to the vehicle or equipment, and insufficient stability and reliability. Finally, the diagnostic connector, as a consumable part, will inevitably wear down after long-term, high-frequency plugging and unplugging. The existing integrated design means that replacement and maintenance require shutting down the entire robotic arm system for debugging, resulting in high maintenance costs and impacting production cycle time. Therefore, there is an urgent need for a more flexible, highly compatible, and easy-to-maintain automated docking device to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent data acquisition device for automotive production lines. Firstly, it solves the problems of extremely poor compatibility and flexibility. The OBD interfaces of different car models vary greatly in position and angle within the cabin, requiring complex re-teaching and reprogramming to adjust the robotic arm's operating path for each new model. This is labor-intensive, error-prone, and unsuitable for modern mixed-line production. Secondly, the rigid connection method places extremely stringent requirements on the absolute positioning accuracy of the robotic arm. Even slight deviations can easily lead to collisions between the robotic arm and the vehicle's interior or the interface itself, resulting in vehicle or equipment damage and insufficient stability and reliability. Finally, the diagnostic connector, as a consumable part, inevitably wears down after long-term, high-frequency plugging and unplugging. The existing integrated design requires the entire robotic arm system to be shut down for testing and adjustment for replacement and maintenance, resulting in high maintenance costs and disruption to production cycle time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent data acquisition device for an automotive production line, comprising a robotic arm, with a plug-in assembly slidably connected to the front end of the robotic arm. The plug-in assembly includes a plug connector, a side fixing block, and a vision sensor. A detachable plug is movably inserted into the plug connector for connecting to an automotive connector. The side fixing block is fixedly connected to both ends of the plug connector. Two sets of vision sensors are provided, each set mounted on the side fixing block. The vision sensors are used to locate and align with the connector. The side fixing block is used to flexibly insert the detachable plug into the connector.

[0006] Preferably, the plug-in assembly includes a screw, which is fixedly connected to the side fixing block and slidably connected to the robotic arm, and a fixing nut is internally threaded onto the screw.

[0007] Preferably, one end of the robotic arm is fixedly connected to a front baffle, the screw is slidably connected inside the front baffle, the fixing nut abuts against the front baffle, and the fixing nut is used to limit the movement of the screw.

[0008] Preferably, the plug-in assembly includes a spring, one end of which is fixedly connected to the back end of the plug-in, and the other end of which is fixedly connected to the front end of the robotic arm. The spring serves to cushion the insertion of the detachable plug.

[0009] Preferably, the back end of the detachable plug is fixedly connected to a connector plate, and the connector has an outer slot and an inner slot. The detachable plug is movably inserted into the outer slot, and the connector plate is movably inserted into the inner slot.

[0010] Preferably, the detachable plug further includes a fixing plate and a socket groove. The socket groove is formed on one side of the detachable plug and the socket plate. The fixing plate is movably inserted into the socket groove. The fixing plate fixes the detachable plug to the socket by fixing bolts.

[0011] Preferably, the robotic arm further includes a data diagnostic instrument and a rear connecting plate. A data transmission line is connected between one end of the data diagnostic instrument and one end of the detachable plug. The rear connecting plate is fixedly connected to the end of the robotic arm and is used to fix the robotic arm to the power mechanism.

[0012] The technical effects and advantages of this utility model are as follows: This device integrates vision sensors and flexible, buffered connectors at the front end of a robotic arm, enhancing compatibility and flexible production capabilities. The vision system automatically identifies the OBD interface poses of different vehicle models, enabling adaptive connector insertion. Furthermore, it significantly reduces collision risk and precision dependence; the flexible design of springs and side fixing blocks absorbs connector deviations, preventing equipment or vehicle damage and improving system stability. Finally, it enables rapid maintenance of vulnerable parts; the modular, detachable plug design allows for replacement of worn parts without downtime, significantly reducing maintenance costs and ensuring continuous and efficient production.
