Description

Technical Field

[0001] The utility model relates to the field of ultrasonic welding heads, in particular to a synchronous double-push type ultrasonic welding head. Background Art

[0002] Ultrasonic welding machine is an industrial welding equipment. The principle is that the generator generates a 20KHz (or 15KHz) high-voltage, high-frequency signal, and converts the signal into high-frequency mechanical vibration through the transducer system. The signal is applied to the plastic workpiece, and the temperature transmitted to the interface is increased through the friction between the workpiece surface and the molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface melts rapidly and then fills the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, and the welding purpose is achieved.

[0003] However, the output power generated by the existing ultrasonic welding head is insufficient, which affects the welding effect. In addition, if the contact end of the existing welding head is worn, the entire welding head must be replaced, which reduces the working efficiency. Utility Model Content

Two symmetrical contact ends are arranged on the welding head base, and after one contact end is worn, the other contact end can be used downward, thereby extending the time for replacing the welding head. By installing an amplitude modulator on the transducer at both ends of the welding head base, the output efficiency of the welding head is improved.

[0014] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0015] Figure 1 It is a structural schematic diagram of the utility model.

[0016] As attached Figure 1 As shown, a synchronous double-push ultrasonic welding head includes a welding head base 1 and a contact end 2. Two mutually symmetrical contact ends 2 are provided in the middle of the welding head base 1. Amplitude modulators 3 are fixedly connected at both ends of the welding head base 1, and a transducer 4 is fixedly connected to the amplitude modulator 3.

[0017] A positioning groove 5 is provided on the welding head base 1 for accurately positioning the welding head base 1 on the connecting seat.

[0018] The welding head base body 1 is provided with a spanner hole 6 for inserting a spanner. When the amplitude modulator 3 is to be assembled and unassembled on the welding head base body 1, the protrusion of the crescent spanner is inserted into the spanner hole 6, and the amplitude modulator 3 can be twisted.

[0019] Threaded holes are provided on the end surfaces of both ends of the welding head base 1 , and the amplitude modulator 3 is threadedly connected to the end of the welding head base 1 .

[0020] Since two upper and lower contact ends 2 are provided in the middle of the welding head base 1, when one contact end 2 is worn, the welding head base 1 can be loosened from the connecting seat, and then the welding head base 1 is rotated 180 degrees so that the unworn contact end 2 faces downward and can continue to be used.

[0021] The transducer 4 can convert electrical energy into mechanical vibration energy, so that the contact end 2 can apply mechanical vibration to the workpiece. The amplitude modulator 3 can control the amplitude of the contact end 2. When the welding head is performing welding operations, the amplitude modulators 3 and transducers 4 at the left and right ends can work together. When the amplitude modulator 3 and transducer 4 at the left end of the welding head base 1 are pushed to the right, the amplitude modulator 3 and transducer 4 at the right end are pulled to the left; then the amplitude modulator 3 and transducer 4 at the left end are pulled to the left, and the amplitude modulator 3 and transducer 4 at the right end are pushed to the right, thereby achieving the purpose of achieving the coordinated vibration of the amplitude modulator 3 and transducer 4 at both ends and greatly improving the output power.

[0022] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
