A Manufacturing Technology For Ultrasonic Riveting Unit With Adjustable Direction, Depth And Pressure Control

A manufacturing technology for ultrasonic riveting unit with adjustable direction, depth and pressure control

New breakthrough in precision welding

In the processing of plastic parts, ultrasonic riveting is widely used. However, traditional equipment often has problems with the direction of the welding head being fixed and the pressure depth being difficult to control. The ultrasonic riveting unit disclosed in this technology has the characteristics of allowing the direction of the welding head to be flexibly adjusted, and at the same time, it can accurately control the welding pressure and depth, which can significantly improve the welding quality and reduce the scrap rate. This is particularly critical and extremely important for the production of precision plastic parts such as automotive parts and electronic casings, right?

The welding head can be turned at will

The upper end of the welding head is connected to a vertical electric telescopic rod, which has the function of automatically adjusting the height. The most critical thing is that the upper end of the vertical electric telescopic rod is equipped with a rotating component. With this component, the operator can easily adjust the direction of the welding head to any direction without having to replace the entire fixture. In this way, facing solder joints at different angles, alignment can be quickly achieved through a simple rotation operation, which greatly shortens the time required for mold change and effectively improves the flexibility of the production line.

Dual monitoring of pressure and depth

During the welding process, the system monitors the pressure value of the vertical electric telescopic rod and the welding displacement in real time, using the pressure proportional valve to accurately maintain the given pressure. At the same time, the laser displacement sensor tracks the depth of the welding head. When the displacement reaches the target value, the ultrasonic wave automatically stops, and then enters the cooling and pressure holding stage. This closed-loop control form significantly improves the consistency of each solder joint, preventing the occurrence of over-welding or virtual welding defects.

Cooling components ensure stability

On the outside of the welding head, a specially designed cooling component can effectively take away heat during continuous welding operations. Ultrasonic welding will generate a lot of heat. If the temperature of the welding head is too high, it will cause uneven melting of the plastic or shorten the life of the welding head. The cooling component ensures that the welding head always works within the appropriate temperature range, extending the service life of the equipment and ensuring stable welding quality.

Installation and fixation are more convenient

There are mounting slots and mounting holes on the mounting plate, which can be quickly fixed on the rack. When making welding adjustments, first confirm the direction of the welding head by rotating the component and adjusting the component, and then fix the mounting plate. The operation is quite simple. There is no need to repeatedly disassemble and install screws to find the angle like traditional equipment, thus saving debugging time. It is especially suitable for the production of complex plastic parts with multiple solder joints and multiple angles.

Automatic reset after pressure maintenance is completed

When the welding is completed, the system enters the pressure holding period, the cylinder moves in the opposite direction of the arrow, and the welding head returns to the initial position on its own, preparing for the welding operation of the next product. The entire process is highly automated and does not require manual intervention. For mass production scenarios, this design can reduce the burden on operators, improve efficiency, and at the same time avoid human errors.
