Description
Technical Field
The invention relates to the technical field of ultrasonic welding, in particular to an ultrasonic welding fixture control device and an ultrasonic welding fixture control system.
Background
Ultrasonic welding is an industrial technique in which an ultrasonic welding device or machine locally applies high frequency ultrasonic vibrations to workpieces held together under pressure to produce a weld spot. Which is commonly used for welding thermoplastic workpieces. Ultrasonic welding processes include placing adjacent or overlapping workpieces on a nest or anvil and directing high frequency vibrations to an interface between the workpieces using an ultrasonic welder. The ultrasonic welder preferably includes a transducer or piezoelectric transducer, an amplifier, and an ultrasonic welding torch, also known as a welding torch (horn). The three elements are tuned to resonate at the same ultrasonic frequency, e.g., 20, 30, 35 or 40kHz. The transducer converts the electrical signal to mechanical vibrations, the amplifier changes the amplitude of the vibrations, and the ultrasonic welding torch clamps the workpiece and applies the mechanical vibrations to the workpiece to join the workpiece. The electronic ultrasonic generator delivers an AC signal having a high power matching the resonant frequency and is preferably controlled by a controller that controls the motion of the pressurized welder and delivers ultrasonic energy. The ultrasonic vibrations generate heat that locally melts the workpiece material to form the welded joint.
When the ultrasonic welding device is used for welding workpieces to be welded with different shapes, a welding head and a clamp with specific shapes are often adopted, the application range of the method is small, the production cost is greatly increased, gaps are also generated in common mechanical clamps, and the stability of the workpieces cannot be ensured.
Disclosure of Invention
The applicant found that ultrasonic welders have a nominal maximum welding force, which is mainly connected by means of relative movement friction melting of the two parts of the workpiece to be welded, when the clamps clamping the workpiece at the fixed part are not stable enough or have a gap, ultrasonic energy can be dispersed outwards, so that the welding effect is poor, and the problem is avoided as much as possible by adopting different types of workpieces to design different clamps in the existing clamps.
However, for workpieces to be welded with different shapes, the method has a small application range, the production cost is greatly increased, gaps are also generated by common mechanical clamps, and the stability of the workpieces cannot be ensured.
The applicant has also found that the ultrasonic welding apparatus converts the current 50/60Hz electrical frequency into 20KHz or 40KHz electrical high frequency electrical energy by a transistor function device, which is supplied to the transducer. The converter converts electric energy into mechanical vibration energy for ultrasonic waves, the pressure regulating device is responsible for transmitting the converted mechanical energy to a welding head of the ultrasonic welding machine, the welding head is an acoustic device for directly transmitting the mechanical vibration energy to a product to be pressed, and in the welding process, the vibration of the welding head is very severe and the speed change is quite large; while the stiffness of a non-newtonian fluid will be improved with greater velocity changes.
Non-newtonian fluids refer to fluids that do not satisfy newtonian viscosity laws of experiment, i.e., fluids whose shear stress and shear strain rate are not linear. The plastic has the characteristics of weak strength and strong strength, can be hardened when the surface of the plastic is pressed, has certain solid characteristics, and can be in a soft state like liquid when the surface is not pressed.
