Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an ultrasonic welding head structure. Background Technology

[0002] The ultrasonic welding head is a key component in ultrasonic welding equipment. It is also known as an ultrasonic welding mold or ultrasonic transducer. Ultrasonic welding heads are widely used for welding materials such as plastics and metals. In plastic welding, they are often used to join plastic parts in industries such as automotive parts, electronic and electrical housings, medical devices, and toys. In metal welding, they can be used to weld lithium battery electrodes, electronic component leads, and precision metal parts.

[0003] Typically made of high-strength, wear-resistant metal materials, such as titanium alloys, aluminum alloys, or tool steel, it is mainly used to transfer the high-frequency mechanical vibration energy generated by the ultrasonic transducer to the workpiece to be welded. The high-frequency vibration causes the workpiece surfaces to rub against each other, generating heat, which in turn causes the workpieces to reach the melting point at the contact surface and fuse together, thus achieving the purpose of welding.

[0004] Existing ultrasonic welding heads suffer from significant ultrasonic energy loss when welding metals, which can lead to a short lifespan for the ultrasonic welding heads and increase manufacturing costs. Furthermore, in the metal foil welding industry, most welding teeth are sharp, which can easily cause unevenness and damage to the products during welding, reducing production efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an ultrasonic welding head structure to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic welding head structure, including a handle, a welding head is installed at one end of the handle, and a transmission rod is installed at both ends of the welding head, and a handle is provided at the other end of the transmission rod. The inner wall of the welding head has a central hole, and welding surfaces are provided at both ends of the welding head. Multiple welding stations are provided on the surface of the welding surfaces.

[0007] By adopting the above technical solution, and through the setting of multiple welding stations and dual welding heads, it is possible to use them in both directions, which indirectly improves the welding life. The welding teeth of the welding station are four-sided frustums, which effectively reduces the phenomenon of unevenness and damage to the product caused by the welding teeth. This makes the surface of the welded product smoother and stronger, which is particularly suitable for metal foil welding. Through the setting of the central hole, which is placed at the center of the ultrasonic welding head, since the amplitude is a left-right reciprocating amplitude, when the welding head welds the object downwards, the welding stress will spread along the welding station to both ends. Some of the upward stress will be blocked by the central hole and transferred to the other welding head, thereby making the ultrasonic welding head welding more stable and extending the life of the ultrasonic welding head.

[0008] The present invention is further configured such that the welding teeth of the welding table are truncated squares.

[0009] Preferably, this effectively reduces the phenomenon of unevenness and damage to the product caused by weld teeth, resulting in a smoother surface and higher strength of the welded product.

[0010] The present invention is further configured such that the handle, the transmission rod and the welding head are an integral structure.

[0011] As a preferred option, this effectively improves the service life of the welding head.

[0012] The present invention is further configured such that the outer wall of the handle is provided with multiple sets of positioning holes, and the multiple sets of positioning holes are arranged opposite to each other.

[0013] Preferably, it facilitates the connection between the welding head and the equipment.

[0014] The present invention is further configured such that the welding surface and the positioning hole are located on the same horizontal line, and the welding surface and the positioning hole are arranged opposite to each other.

[0015] As a preferred method, improving the accuracy of welding head installation effectively enhances the stability of the welding surface during operation.

[0016] The present invention is further configured such that the welding head has a central hole at both ends away from the welding surface, and the central hole is elliptical.

[0017] Preferably, the central hole is placed at the center of the ultrasonic welding head. Since the amplitude is a reciprocating amplitude, when the welding head welds the object downwards, the welding stress will spread along the welding table to both ends. Some of the upward stress will be blocked by the central hole and transmitted to the other side of the welding head, thereby making the ultrasonic welding head welding more stable and extending the life of the ultrasonic welding head.

[0018] The present invention is further provided that a groove is provided between the handle and the transmission rod, and a threaded connection hole is provided in the groove.

[0019] Preferably, a threaded connection hole is added between the handle and the transmission rod to facilitate the connection of the welding head to the equipment.

[0020] The main benefits of this type are as follows:

[0021] 1. This utility model, through the setting of multiple welding stations and double welding heads, can be used in both directions, indirectly improving the welding life. The welding teeth of the welding station are four-sided truncated pyramids, which effectively reduces the phenomenon of unevenness and damage to the product caused by welding teeth, making the welded product surface smoother and stronger, especially suitable for metal foil welding.

[0022] 2. By setting a central hole, the present invention is located at the center of the ultrasonic welding head. Since the amplitude is a reciprocating amplitude, when the welding head welds the object downwards, the welding stress will spread along the welding table to both ends. Some of the upward stress will be blocked by the central hole and transmitted to the other side of the welding head, thereby making the ultrasonic welding head welding more stable and extending the life of the ultrasonic welding head.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] First embodiment:

[0032] Please see Figures 1-4The ultrasonic welding head includes a handle 1, with a welding head 3 installed at one end of the handle 1. Both ends of the welding head 3 are equipped with transmission rods 2, and the other end of the transmission rods 2 is also equipped with the handle 1. A central hole 30 is formed on the inner wall of the welding head 3, and welding surfaces 31 are provided at both ends of the welding head 3. Multiple welding platforms 310 are provided on the surface of the welding surfaces 31. With the multiple welding platforms 310, the dual welding heads 3 can be used in both directions, indirectly improving the welding life. The welding teeth of the welding platforms 310 are truncated pyramids, effectively reducing the unevenness and damage caused by the welding teeth, resulting in a smoother surface and higher strength in the welded product, making it particularly suitable for metal foil welding. The central hole 30 is located at the center of the ultrasonic welding head. Because the amplitude is a reciprocating amplitude, when the welding head 3 welds an object downwards, the welding stress diffuses along the welding platforms 310 to both ends. Some of the upward stress is blocked by the central hole 30 and transmitted to the other welding head, thus making the ultrasonic welding head weld more stable and extending its lifespan.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The welding teeth of the welding table 310 are truncated squares, which effectively reduces the phenomenon of unevenness and damage to the product caused by the welding teeth, resulting in a smoother surface and higher strength of the welded product.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The handle 1, the transfer rod 2, and the welding head 3 are integrated into one structure, which effectively improves the service life of the welding head.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The outer wall of the handle 1 is provided with multiple sets of positioning holes 10, and the multiple sets of positioning holes 10 are arranged opposite each other to facilitate the connection between the welding head and the equipment.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 , Figure 3 The welding surface 31 and the positioning hole 10 are located on the same horizontal line, and the welding surface 31 and the positioning hole 10 are set opposite to each other, which improves the accuracy of the welding head installation and effectively improves the stability of the welding surface 31 during operation.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The welding head 3 has a central hole 30 at both ends away from the welding surface 31. The central hole 30 is elliptical and is located at the center of the ultrasonic welding head. Since the amplitude is a reciprocating amplitude, when the welding head 3 welds the object downwards, the welding stress will spread to both ends along the welding table 310. Some of the upward stress will be blocked by the central hole 30 and transferred to the other side of the welding head, thereby making the ultrasonic welding head welding more stable and extending the life of the ultrasonic welding head.

[0038] Second embodiment:

[0039] Please see Figures 1-3 The difference between Embodiment 2 and Embodiment 1 is that, while retaining Embodiment 1, a threaded connection hole 4 is added between the handle 1 and the transmission rod 2 to facilitate the connection of the welding head with the equipment.

[0040] A threaded connection hole 4 is provided between the handle 1 and the transmission rod 2. When the welding head is installed and fixed to the equipment through the threaded connection hole 4 at one end, it can be quickly disassembled. This solves the problem that the welding head with a single threaded hole could not be used due to damage to the threaded connection hole 4. With this design, the threaded connection holes 4 at both ends of the ultrasonic welding head can be interchanged and installed, thus improving the service life of the welding head.

[0041] In practical operation, this utility model is as follows:

[0042] Firstly, the ultrasonic welding head consists of a welding head 3, two handles 1, and two transmission rods 2, symmetrically positioned on both sides of the welding head 3. The handles 1 are connected to the welding head 3 via the transmission rods 2, and the handles 1 and transmission rods 2 are integrated with the welding head 3. The welding head body is connected to the transducer (a device that converts electrical energy into mechanical vibration energy; the high-frequency vibrations it generates need to be transmitted to the welding head body in a specific way) via the handles 1. This symmetrical fixing method at both ends ensures smoother welding, reduces welding deformation, and effectively improves the welding effect of the ultrasonic welding head.

[0043] Furthermore, since the transducer is connected to the handle 1 of the ultrasonic welding head 3 via an amplitude modulator, the amplitude transmitted by the transducer is also amplified by the amplitude modulator and transmitted to the handle 1 of the ultrasonic welding head 3. The handle 1 smoothly transmits the amplitude to the transmission rod 2, and the other end of the transmission rod 2 is connected to the welding head 3. The welding stress of the welding head 3 is released more smoothly from the gradually expanding parts at both ends, thereby increasing the service life of the welding head. The welding table 310 is above the welding surface 31 and protrudes outward. The middle hole 30 is placed at the center of the ultrasonic welding head. Since the amplitude is a left-right reciprocating amplitude, when the welding head 3 welds the object downward, the welding stress will spread to both ends along the welding table 310. Some of the upward stress will be blocked by the middle hole 30 and transmitted to the other side of the welding head, thereby making the ultrasonic welding head welding more stable and extending the service life of the ultrasonic welding head.

[0044] The multi-stage welding station 310 is specially designed for flexible connections that need to be welded in multiple locations. It can perfectly weld the flexible connection in one go, and multiple welding stations 310 can achieve a more secure welding effect in multiple locations of the product.

[0045] Secondly, the ultrasonic welding head has threaded connection holes 4 at both ends. It can be installed and fixed to the equipment through the threaded connection hole 4 at one end of the welding head, and can be quickly disassembled. This effectively solves the problem that the previous single threaded hole welding head could not be used due to damage to the threaded connection hole 4. With this design, the threaded connection holes 4 at both ends of the ultrasonic welding head can be replaced and installed.

[0046] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
