Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seat tightening, in particular to an online full-automatic tightening system for automobile seat. BACKGROUND

[0002] In the current rapid development of the automobile manufacturing industry, the assembly quality and production efficiency of automobile seats, as core components affecting driving and riding comfort and safety, are directly related to the manufacturing level of the whole vehicle. Among them, the bolt connection process of key components such as seat frames, slide rails, and angle adjusters is the core link to ensure the stability and reliability of seat structure and function, and has very high requirements for the precision, consistency and efficiency of bolt tightening. Currently, there are mainly two types of operation modes for the bolt tightening process of automobile seats: One is the traditional manual tightening mode, which relies on the operator to hold the tightening tool and tighten the bolts one by one. This mode not only requires a large amount of manual labor, but is also affected by subjective factors such as the skill level, physical condition, and work concentration of the operator, making it prone to problems such as bolt tightening torque deviation, missed tightening, and incorrect tightening, resulting in unstable seat assembly quality and safety hazards. At the same time, manual operation is low in efficiency and difficult to adapt to the increasing production capacity demand of the automobile industry, especially in the multi-model mixed production scene, the time cost of manual switching of operation processes is high, further restricting the overall pace of the production line. The other is the semi-automatic tightening device operation mode, which partially replaces manual operation but still has obvious limitations. This type of device usually requires manual assistance for feeding and positioning the workpiece, and cannot achieve full-process automation connection from workpiece conveying, grabbing, positioning to tightening. For example, in the workpiece conveying link, it mostly relies on manual operation to move the seat components to the tightening station, which not only increases the labor intensity of the operator, but also easily causes workpiece positioning deviation due to collision and misplacement during the moving process, affecting the tightening precision; In the bolt feeding link, traditional semi-automatic devices mostly use manual feeding, which may cause equipment downtime if the feeding is not timely, reducing production continuity. In addition, most semi-automatic tightening devices lack real-time monitoring and feedback mechanisms, and cannot accurately record and issue abnormal warnings for key parameters such as torque and angle during the tightening process. Once quality problems occur, it is difficult to trace the root cause, which is not conducive to the continuous improvement of production quality. Therefore, how to solve the problems of low automation level, low production efficiency, unstable tightening precision, and insufficient safety protection in the bolt tightening process of automobile seats has become a key requirement for the upgrading and transformation of current automobile seat assembly production lines.
