Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding, in particular to a novel ultrasonic welding head. Background Art

[0002] Ultrasonic welding is based on the physical principle of sound waves. It uses the properties of sound waves propagating in materials to achieve welding through vibration energy transfer. When the vibration generator generates a high-frequency vibration signal, the transducer converts it into mechanical vibration and transmits it to the welding head. The welding head is composed of a metal vibrator, a focusing block, a contact surface, etc. When the vibration energy is transmitted to the welding workpiece, high-frequency vibration will be generated on the surface of the workpiece, thereby generating heat energy to melt the surface of the workpiece to be welded. During this process, the welding head will apply a certain amount of pressure to further enhance the reliability of the welded joint.

[0003] Ultrasonic welding requires the bottom of the welding head to be leveled, otherwise the contact surface between the welding head and the plastic will not match, and ultrasonic waves will cause concentrated damage. Existing ultrasonic welding machines use leveling screws to adjust and observe whether the welding head is level. It is difficult for the human eye to distinguish the level of the welding head, and the error is large, resulting in loose welding. Utility Model Content

[0004] The utility model discloses a novel ultrasonic welding head, which aims to solve the technical problem that the existing ultrasonic welding machine uses a level screw to adjust and observe whether the welding head is level, and it is difficult for human eyes to distinguish the level of the welding head, resulting in a large error and unstable welding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel ultrasonic welding head comprises a base and also comprises:

[0007] The correction mechanism includes a first flange and a second flange, the bottom of the first flange is movably connected with four evenly distributed springs, the bottom of the springs is movably connected with the top outer wall of the second flange, four evenly distributed adjustment bolts are arranged between the first flange and the second flange, a transducer is arranged at the bottom of the second flange, and a welding head body is arranged at the bottom of the transducer.

[0008] In this solution, during welding, the welding head body moves downward to press the workpiece, the spring is squeezed and deformed, and the welding head body can automatically adjust its position when pressed, so that the bottom of the welding head body remains horizontal, thereby making the contact surface of the welding head body coincide with the workpiece, thereby improving the welding quality.

[0009] In a preferred solution, a threaded hole is formed at the bottom of the first flange, and the adjusting bolt is rotatably connected in the threaded hole. A circular hole is formed at the top of the second flange, and the adjusting bolt passes through the circular hole. A bolt head is provided at the bottom of the adjusting bolt, and a fixing bolt is provided on the outer wall of the adjusting bolt, and the fixing bolt is close to the bottom of the first flange.

[0010] By adopting the above scheme, turn the bolt head, adjust the four adjusting bolts respectively, observe the level of the second flange, adjust the level of the second flange and then turn the fixing bolt to lock the position of the adjusting bolt to keep the bottom of the second flange level, thereby improving the welding effect.

[0011] As can be seen from the above, a new type of ultrasonic welding head includes a base and also includes:

[0012] The correction mechanism includes a first flange and a second flange, the bottom of the first flange is movably connected with four springs evenly distributed, the bottom of the spring is movably connected with the top outer wall of the second flange, four evenly distributed adjustment bolts are arranged between the first flange and the second flange, a transducer is arranged at the bottom of the second flange, and a welding head body is arranged at the bottom of the transducer.
