Description

Technical Field

[0001] The utility model relates to the technical field of seat belt buckle feeding devices, in particular to an automatic gripping and feeding device for a seat belt buckle. Background Art

[0002] Seat belts are important safety devices in vehicles such as cars, and their performance stability and reliability are crucial. As a key component of seat belts, the assembly quality and efficiency of seat belt buckles directly affect the use effect and production cost of seat belts. Seat belt buckle assembly generally uses the loading component to automatically put the groove seat into the fixture, and the conveying device moves the groove seat to the bow and spring assembly station to assemble the bow and spring assembly, and then the groove seat moves to the latch assembly station to assemble the latch, and then the spring assembly station assembles the spring, and then the lock pin assembly station assembles the lock, and then the lock assembly station assembles the lock, and then the button assembly station assembles the button, and finally the assembled seat belt buckle is unloaded through the unloading station.

[0003] Existing unloading devices generally use mechanical claws to clamp the side of the seat belt buckle for unloading. First, the button of the seat belt buckle is usually made of lightweight and brittle plastic material to reduce weight while maintaining the necessary structural strength. When the mechanical claw directly clamps the side of the button, due to the small contact area and concentrated pressure, it is easy to cause scratches or even cracks on the button surface, which not only affects the appearance quality of the product, but also may weaken the overall structural strength of the buckle, posing a safety hazard. Secondly, the design of modern seat belt buckles is becoming increasingly complex, and the side of the assembled buckle body is often equipped with protruding springs for locking or releasing functions. These springs are usually slender and have high requirements for position accuracy. Traditional clamping devices will clamp the springs during the clamping process, causing unnecessary bending or displacement of the springs. The deformation of the spring will directly affect the functionality and reliability of the buckle. In severe cases, it may cause the buckle to fail and fail to meet safety standards.
