Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ultrasonic welding, in particular to a plate ultrasonic welding clamp. BACKGROUND

[0002] Ultrasonic welding is to convert 50 / 60 Hz current into 15, 20, 30 or 40 KHz electric energy by an ultrasonic generator. The converted high-frequency electric energy is converted into mechanical motion of the same frequency by a transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude-changing horn devices. 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. Since plastics have poor thermal conductivity, the heat cannot be dissipated in time and accumulates in the welding area, causing the contact surfaces of the two workpieces to be welded to melt rapidly. After pressing under certain pressure, they are fused into one, and after the workpiece solidifies, a solid molecular chain is formed to complete the welding. It is worth mentioning that the strength of the welded position after ultrasonic welding can approach the strength of the raw material.

[0003] The ultrasonic welding device and method disclosed in Chinese patent application publication CN112976589B can facilitate film replacement and reduce waste caused by insufficient or excessive feeding. However, when welding plate workpieces, the welding clamp needs to clamp and fix two plates. When the clamp is tightly attached to the plates, the plates will be vibrated by the ultrasonic waves and will also rub against the clamp at high speed, causing the clamp to vibrate and generate heat, causing the clamp and the plates to stick together, reducing the flatness of the plate edges, causing welding gaps at the clamping points with other plates, and causing the melted plastic to stick to the clamp. In addition, the existing clamp is not convenient to control the clamping force when clamping the plates, and it is easy to damage the material when clamping brittle materials, causing unnecessary waste.

Beneficial effects

[0014] Compared with the prior art, the present application provides a plate ultrasonic wave regulation and control welding clamp, which has the following beneficial effects:

[0015] The plate ultrasonic wave regulation and control welding clamp is provided with a size adjusting module, which can adjust the position of the positioning and clamping module by measuring the size of the plate during welding of plates of different sizes, and the two clamping plates are moved closer to each other to compress the jacking spring, so that the non-slip pad is separated from the side wall of the sliding groove.

[0016] This ultrasonically controlled welding fixture for plates features a movable clamping module. Inside this module, the clamping springs are compressed at varying degrees, allowing the pressure of the pressure-reducing plate on the plates to differ. By adjusting the screw, the position of the clamping switch can be changed. The scale on the screw surface indicates the clamping force provided by the clamping switch when the spring plate is engaged. This allows for adjustment of the clamping force according to different plate materials, preventing excessive clamping force from damaging the plates while simultaneously securing the plates with the maximum possible clamping force for easy welding.

[0017] This ultrasonically controlled welding fixture for plates features an acoustic adjustment module. During ultrasonic welding, the module senses the welding start time. When the ultrasonic welding head on the welding module presses the plate against it, the plate directly contacts the pressure relief plate, transmitting the vibration caused by the ultrasonic waves to the electric rod. As the acoustic adjustment module on the electric rod vibrates, the vibration spring causes the magnet to cut magnetic lines of force within it. This transmits the electrical signal from the induction coil to the control panel, causing the electric rod to shorten and compensate for the compression of the clamping spring. This allows the pressure relief plate to move away from the plate, preventing the heat generated by the vibration between the pressure relief plate and the plate from melting the plate and welding it to the fixture.
