[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0020] like Figure 1 to Figure 2 As shown, the utility model proposes an ultrasonic welding machine for plastic parts, including a base 1, on which a workbench 2 is arranged. The base 1 is the foundation of the whole machine and provides stable support. The workbench 2 is arranged on the base 1 and is the main platform for plastic parts welding operation; a column 3 is arranged at one end of the base 1, on which a lifting assembly is arranged, and a welding assembly is arranged at the bottom of the lifting assembly, and the processing end of the welding assembly is arranged toward the workbench 2. When the lifting assembly drives the welding assembly to descend, the processing end of the welding assembly will contact the plastic parts placed on the workbench 2 to perform ultrasonic welding operation; and also includes a processing seat, the bottom of the processing seat is arranged on the workbench 2, and the top of the processing seat is provided with a first positioning member 4 and a second positioning member 5, the first positioning member 4 is provided with a positioning notch 1, and the second positioning member 5 is provided with a positioning notch 2, and the positioning notch 1 and the positioning notch 2 together form a positioning groove 6 for accommodating plastic parts, which ensures the stability and accuracy of the plastic parts during the welding process and improves the welding quality.

[0021] In this embodiment, the first positioning member 4 is fixedly connected to the processing seat, and the second positioning member 5 is in abutment contact with the processing seat. The plastic part is positioned by the first positioning member 4 and the second positioning member 5. The first positioning member 4 provides a stable positioning reference for the plastic part. The second positioning member 5 can be fine-tuned as needed and is connected to the processing seat in abutment contact, so that it can flexibly adapt to the positioning requirements of different plastic parts.

[0022] In this embodiment, a first fixing unit 7 and a second fixing unit 8 are provided on the workbench 2, one end of the first fixing unit 7 and the second fixing unit 8 are provided on the top surface of the workbench 2, the fixed ends of the first fixing unit 7 and the second fixing unit 8 are in contact with the top of the processing seat, and the processing seat is fixed on the workbench 2 by the first unit and the second fixing unit 8.

[0023] In this embodiment, a third fixing unit 9 is provided on the workbench 2, one end of the third fixing unit 9 is provided on the top surface of the workbench 2, and the fixed end of the third fixing unit 9 is provided on the second positioning member 5, and the second fixing member is fixed on the processing seat through the third fixing unit 9.

[0024] In this embodiment, the lifting assembly includes a lifting platform 10, which is connected to the welding assembly and is used to drive the welding assembly to move along its own axial direction; the lifting platform 10 is connected to the welding assembly and serves as a support and driving part of the welding assembly. When the height of the welding assembly needs to be adjusted, the lifting platform 10 will move along its axial direction. The height adjustment range of the lifting platform 10 can be set as needed to adapt to plastic parts of different thicknesses or heights.

[0025] In this embodiment, the welding assembly includes an ultrasonic oscillator 11 and a welding probe 12. The welding probe 12 is arranged on the output end of the ultrasonic oscillator 11, and the welding probe 12 is used to perform welding processing on the welding parts. When the power is turned on, the ultrasonic oscillator 11 will start to generate high-frequency vibrations, which are then converted into ultrasonic energy. This ultrasonic energy has the characteristics of high frequency and high energy, and can effectively act on the plastic parts to generate friction heat. During the welding process, the welding probe 12 will also apply a certain amount of pressure to ensure close contact between the plastic parts. The combined effect of this pressure and ultrasonic energy enables the plastic parts to be firmly welded in a short time.

[0026] The use process and principle of the utility model are as follows: First, the operator places the plastic part to be welded in the positioning groove 6 on the processing seat to ensure that the plastic part is tightly matched with the positioning notch 1 and the positioning notch 2. Then, by adjusting the position of the second positioning member 5, it forms a stable positioning structure together with the first positioning member 4. Next, the operator uses the first fixing unit 7 and the second fixing unit 8 to fix the processing seat on the workbench 2. This ensures the stability of the processing seat during the welding process and prevents welding failure caused by vibration or movement. When everything is ready, the operator starts the welding process. The lifting platform 10 will drive the welding assembly to descend so that the welding probe 12 contacts the plastic part. Under the action of the ultrasonic oscillator 11, the welding probe 12 generates high-frequency vibrations and transmits ultrasonic energy to the plastic part. At the same time, the welding probe 12 applies a certain pressure to enable the plastic part to be welded under the action of frictional heat. After the welding is completed, the operator checks the welding quality of the plastic part to ensure that there are no defects or flaws. Then, the welded plastic parts are taken out from the processing seat for subsequent processing or assembly.
