Application of Ultrasonic Welding to Anti-theft Buckles in Supermarkets

Supermarket anti-theft buckle is a very common product in major supermarkets, but how is our ultrasonic welding equipment applied to this product?

First of all, let's understand the structure and principle of the anti-theft buckle:

The anti-theft buckle is composed of a steel needle, a plastic casing and a lock cylinder. The lock cylinder is actually a simple device formed by three steel balls, a steel ring and a spring. The steel ball is normally closed by the spring thrust. When the steel needle is inserted, the steel ball is tightly buckled. in the gap of the needle. The supermarket anti-theft buckle is opened mainly by the magnetic steel above 8000GS to suck the three steel balls stuck with the steel needle in the lock cylinder away from the steel needle, and the steel needle can be smoothly pulled out from the magnetic buckle. Magnetic steel above 8000GS is the strong magnetic unlocker commonly used by cashiers

Generally, the plastic shell of the anti-theft buckle is made of ABS or other thermoplastic materials. After the internal parts are assembled, they can be welded and packaged by an ultrasonic welding machine. If there is a requirement for output, we can also use a multi-station turntable ultrasonic welding machine, which can greatly improve efficiency!
