[0002] Automotive clips are components used to connect or secure interior vehicle components, typically made of metal or plastic. Their exceptional strength and durability effectively withstand the vibration and impact of driving. There are numerous types of automotive clips, including push-in, flush-mount, plastic nuts, and pipe clamps, each with its own unique features to meet diverse installation requirements. The primary function of automotive clips is to secure and connect various components within the vehicle, ensuring driving safety. They are widely used in bumpers, fenders, fenders, trunks, and other areas, ensuring driving safety by securely connecting these components.

[0003] In the existing technology, automobile buckles are usually installed manually by workers, and the number of buckles used in a car is generally 850-960. It takes 60-70 workers to assemble these buckles simultaneously. However, the accuracy of manual assembly by workers cannot be uniform, and the loss of buckles will increase due to human errors. During the assembly process, workers' fingers will be abraded and deformed due to long-term assembly of buckles. Secondly, a large number of buckles require more manpower and time, which not only reduces the accuracy of buckle assembly, but also increases the production cost of the enterprise and reduces the production efficiency of automobiles. Based on this, an automatic assembly jig for universal automobile buckles by robots is proposed. Utility Model Content

[0028] The robot body 1 receives the electrical signal from the external sensor, and the controller 2 controls the operating position of the buckle fixture. The left clamp 7 and the right clamp 14 work together to clamp the buckle 8. A spring 12 is provided between the left clamp 7 and the right clamp 14 to prevent the clamping force from being too large and damaging the buckle fixture during the clamping process. A limiting groove is provided at the bottom of the L-shaped limiting plate 15 to facilitate the top of the buckle 8 to be embedded in the limiting groove, and the left clamp 7 and the right clamp 14 cooperate to clamp the buckle 8 more stably, which is convenient for the subsequent assembly process.

[0029] The rear end of the L-shaped limiting plate 15 is fixedly connected to the front ends of the first half gear 16 and the second half gear 17 .
