Novel ultrasonic efficient rivet welding machine

Abstract

The invention relates to the field of ultrasonic rivet welding, in particular to a novel ultrasonic efficient rivet welding machine.The machine comprises a welding mechanism used for ultrasonic welding, a lifting mechanism used for transferring a workpiece to be machined to the welding mechanism and located under the welding mechanism, a supporting mechanism used for pushing the workpiece to be machined to the lifting mechanism, and a pushing mechanism used for discharging the machined workpiece out of the lifting mechanism, wherein the supporting mechanism and the pushing mechanism are located on the two sides of the welding mechanism respectively, the welding mechanism comprises an ultrasonic vibrator and a welding head, the ultrasonic vibrator and the welding head are fastened and connected, the lifting mechanism comprises a servo motor and a lifting table, and the lifting table is provided with a welding jig; welding is finished on the welding mechanism, and the machined workpiece is pushed away from the lifting mechanism by the pushing mechanism while the lifting mechanism descends to restore.By the adoption of the machine, production rate can be effectively increased, and through action cooperation of different mechanisms, time is saved greatly and production efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of ultrasonic riveting welding, in particular to a novel ultrasonic high-efficiency riveting welding machine. Background technique [0002] Ultrasonic welding is to convert 50 / 60 Hz current into 15, 20, 30 or 40KHz electric energy through an ultrasonic generator. The converted high-frequency electric energy is converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of horn devices that can change the amplitude. The welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction and melts the plastic. Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films. [0003] However, the working steps of the riveting welding machine in the existing equipment are cumbersome, ...

AI Technical Summary

Problems solved by technology

[0003] However, the working steps of the riveting welding machine in the existing equipment are cumbersome, each action can only be performed independently, and it takes a lot of time, and the existing equipment generally uses the welding head to move up and down to rivet weld the product, and the ultrasonic vibrator will follow The welding head moves up and down, which increases the instability factor, greatly affects the service life of the equipment and generates more noise

In the processing equipment of the prior art, there are 13 actions and riveting actions to be performed by the grasping manipulator in one beat, and each action requires separate time, which seriously reduces the production efficiency
