[0031] Please see Figure 1 and Figure 2In the automotive manufacturing industry, ultrasonic welding, as a highly efficient joining technology, is widely used due to its advantages such as fast welding speed, high quality, and environmental friendliness. Since welding often requires a combination of multiple welding processes, multi-station ultrasonic welding has emerged, which can greatly improve welding efficiency. However, traditional multi-station welding is fixed in position, requiring a robotic arm to move the object to be welded during welding, and it also has the problem of relatively large footprint. Therefore, this application provides a multi-station ultrasonic welding device, including a support frame assembly 1, with a support plate 2 disposed on the inner side of the frame assembly 1 near the bottom.

[0032] The support plate 2 is provided with one or more welding stations 5 for welding purposes;

[0033] The frame assembly 1 includes one or more outer skeletons 11. A crossbeam 12 and a base 13 are provided on one side of the multiple outer skeletons 11 that are close to each other. The crossbeam 12 and the base 13 correspond one to one. A welding area is formed between the crossbeam 12 and the base 13 for adaptation to the welding station 5.

[0034] A rotating component 18 is provided in the middle of the inner side of the welding area. The output shaft of the rotating component 18 is adapted to the support plate 2 and is used to control the rotation of the support plate 2, thereby satisfying the placement of welding materials.

[0035] The frame assembly 1 serves to support the entire device. It includes one or more outer frames 11, which are configured according to actual production needs and the size of the device. When a larger welding space and more workstations are required, the number of outer frames 11 can be increased.

[0036] Multiple outer frame members 11 are provided with crossbeams 12 and bases 13 on their adjacent sides, with each crossbeam 12 and base 13 corresponding to the other. A welding area is formed between the crossbeams 12 and bases 13, which is provided to accommodate the welding station 5. The outer frame members 11, crossbeams 12, and bases 13 can be made of high-strength metal materials, such as steel, and are fixed together by welding or bolting to ensure the stability and robustness of the frame assembly 1.

[0037] The support plate 2 is located on the inner side of the frame assembly 1 near the bottom. One or more welding stations 5 are provided on the support plate 2, and the number of welding stations 5 can be adjusted according to the actual welding process requirements. For example, in automotive parts welding, if the welding of an automotive interior part requires three different welding processes, then three welding stations 5 can be set on the support plate 2. Each welding station 5 is equipped with corresponding ultrasonic welding equipment, including core components such as an ultrasonic generator and transducer, for welding the target object.

[0038] The rotating assembly 18 is located in the middle of the inner side of the welding area. The output shaft of the rotating assembly 18 is adapted to the support plate 2, and the rotation of the support plate 2 can be controlled by the rotating assembly 18. The rotating assembly 18 can be driven by a motor, and the output shaft of the motor is fixedly connected to the center of the support plate 2. When the motor starts, the rotation of the motor is transmitted to the support plate 2 through the output shaft, causing the support plate 2 to rotate around the central axis.

[0039] During welding, the object to be welded is placed on a welding station 5 of the support plate 2. The rotating component 18 controls the support plate 2 to rotate according to a preset program, moving the welding station 5 to a suitable welding area for welding. After completing one welding process, the rotating component 18 drives the support plate 2 to rotate again, moving the object to the next welding station 5 for the next welding process, until all welding processes are completed.

[0040] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 Each pair of outer skeletons 11 forms a frame, and a protective net 4 is installed on the inner side of the frame to protect the welding area.

[0041] One of the frames has an open-shaped pick-and-place station 110, and a control box is provided on one side of the pick-and-place station 110.

[0042] A limiting frame 15 is installed on the top of the cross frame 12, and a driving component 16 is provided on the top of the limiting frame 15. The output shaft of the driving component 16 extends through the gap of the cross frame 12 to the welding area, where a welding assembly is installed.

[0043] A reinforcing cross 111 is provided on the inner side of the base 13. A support frame 17 is provided on the top of the reinforcing cross 111 at the bottom of the support plate 2. The support frame 17 and the support plate 2 are stacked together.

[0044] Two outer frame members 11 form a frame, and a protective net 4 is installed on the inner side of the frame. The function of the protective net 4 is to protect the welding area. During ultrasonic welding, although no open flame is produced, tiny debris may fly out. The protective net 4 can effectively block these debris, preventing them from flying outside the welding area and causing injury to the operator. At the same time, the protective net 4 also plays a certain role in isolation, reducing the entry of external dust and other impurities into the welding area and ensuring welding quality. The protective net 4 can be made of metal, such as stainless steel wire mesh, which has a certain strength and corrosion resistance, and is fixed to the inner side of the frame by bolts or clips.

[0045] One of the frames has an open-ended pick-and-place station 110. The pick-and-place station 110 is specifically designed for placing and retrieving the object to be welded. In production processes such as automobile manufacturing, operators can conveniently place the automotive parts to be welded onto the welding station 5 of the support plate 2 from the pick-and-place station 110, or remove the welded finished product from the welding station 5.

[0046] A control box 3 is located on one side of the pick-and-place station 110. The control box 3 is the control center of the entire multi-station ultrasonic welding device, controlling the rotating component 18, the drive component 16, and various welding components. The control box 3 contains controllers, circuit boards, power supplies, and other electronic components. Operators can input welding parameters, rotation angles, welding times, and other commands through the operation panel on the control box 3 to achieve automated control of the device. The control box 3 can also be equipped with a display screen to show the device's operating status, welding parameters, and other information in real time, facilitating monitoring and adjustments by the operator.

[0047] A limit bracket 15 is installed on the top of the cross frame 12, which serves to fix and support the drive component 16. The limit bracket 15 can be made of metal and is fixed to the top of the cross frame 12 by welding or bolting. The drive component 16 is located on the top of the limit bracket 15, and the drive component 16 can be a cylinder or an electric actuator. The output shaft of the drive component 16 extends through the gap in the cross frame 12 to the welding area, where a welding assembly is installed.

[0048] When welding is required, the output shaft of drive component 16 extends downward, moving the welding assembly downward to bring it close to the target object for welding. After welding is completed, the output shaft of drive component 16 retracts upward, returning the welding assembly to its initial position. Precise control of drive component 16 ensures that the welding assembly performs welding under appropriate pressure and position, improving welding quality.

[0049] A reinforcing cross 111 is provided on the inner side of the base 13. The reinforcing cross 111 can enhance the structural strength of the base 13 and improve the stability of the entire device. The reinforcing cross 111 can be made of welded metal tubing and fixed to the inner side of the base 13 by welding or bolting.

[0050] A support frame 17 is installed at the top of the reinforcing cross 111, located at the bottom of the support plate 2. The support frame 17 is stacked with the support plate 2. The support frame 17 supports the support plate 2, ensuring its stability during rotation. The support frame 17 can be in the form of multiple support columns, with the tops of the columns contacting the bottom of the support plate 2 and evenly distributed below the support plate 2 to ensure uniform stress distribution. The support frame 17 can be made of high-strength metal to ensure it can withstand the weight of the support plate 2 and the object to be welded.

[0051] Please see Figure 2 , Figure 4 , Figure 5 , Figure 6 The bottom of the outer edge of the support frame 17 is provided with a telescopic member 19, and the bottom of the telescopic member 19 is fixed to the top of the reinforcing cross 111.

[0052] The piston rod of the telescopic member 19 is provided with a positioning block at the top, and the positioning block is fixed to the bottom of the outer edge of the support frame 17.

[0053] The bottom of the reinforced cross 111 is provided with support feet 14, and there are one or more support feet 14, which are arranged in a circular array around the vertical center line of the reinforced cross 111.

[0054] A control box 3 is provided on one side of the pick-and-place station 110, and the control box 3 is installed on one of the frames.

[0055] A second driving component 112 is provided on one side of the rotating component 18, and the second driving component 112 is fixed to the top of the reinforcing cross 111 along with the rotating component 18.

[0056] In the device, a telescopic component 19 is provided at the bottom of the outer edge of the support frame 17, and the bottom of the telescopic component 19 is fixed to the top of the reinforcing cross 111. The telescopic component 19 can be a component capable of telescopic function, such as a cylinder or an electric push rod. The telescopic component 19 plays an important role, as it can adjust the height of the support frame 17 according to actual welding requirements. For example, in the welding process of different automotive parts, there may be different requirements for the height of the support plate 2. Through the telescopic movement of the telescopic component 19, the support plate 2 can be placed at a suitable height position to cooperate with the welding assembly for precise welding.

[0057] A positioning block is provided at the top of the piston rod of the telescopic component 19, and the positioning block is fixed to the bottom of the outer edge of the support frame 17. The function of the positioning block is to ensure the stability and accuracy of the connection between the telescopic component 19 and the support frame 17. When the piston rod of the telescopic component 19 extends or retracts, the positioning block can prevent the support frame 17 from shaking or shifting, ensuring that the support frame 17 can smoothly adjust its height with the movement of the telescopic component 19, thereby ensuring the positional accuracy of the target object to be welded on the support plate 2 and improving the welding quality.

[0058] The bottom of the reinforcing cross 111 is equipped with support feet 14. There can be one or more support feet 14, arranged in a circular array around the vertical center line of the reinforcing cross 111. The support feet 14 support the entire device, and the circular array arrangement of the support feet 14 ensures more even force distribution and improves the stability of the device. In practical applications, if the device is small and lightweight, a smaller number of support feet 14 may suffice; however, for large, multi-station ultrasonic welding devices, due to their greater weight, it may be necessary to increase the number of support feet 14 to ensure that the device does not sway or tilt during operation. The support feet 14 can be made of rubber or shock-absorbing materials, thus providing both support and shock absorption, reducing the impact of vibrations generated during operation on welding quality.

[0059] A control box 3 is installed on one side of the pick-and-place station 110, mounted on one of the frames. As the control core of the entire multi-station ultrasonic welding device, the control box 3 is conveniently located on one side of the pick-and-place station 110, allowing operators to easily operate and monitor the device while placing and removing the workpiece. While placing or removing the workpiece, operators can set and adjust welding parameters, the rotation angle and speed of the rotating component 18, and the extension / retraction amount of the telescopic component 19 via the control panel on the control box 3. The control box 3 integrates various control circuits and electronic components, enabling precise control of the coordinated operation of all components to ensure the smooth progress of the welding process.

[0060] A second driving component 112 is provided on one side of the rotating assembly 18, and the second driving component 112 is fixed to the top of the reinforcing cross 111. The second driving component 112 can provide additional power support for the rotating assembly 18, ensuring that the rotating assembly 18 can drive the support plate 2 to rotate more stably and accurately. In some cases, when the target object to be welded placed on the support plate 2 is heavy or requires rapid and frequent rotation, the power of the rotating assembly 18 alone may not be sufficient. At this time, the second driving component 112 can play a role, working in conjunction with the rotating assembly 18 to improve the efficiency and accuracy of rotation. The second driving component 112 can be a motor or other power equipment, which transmits power to the rotating assembly 18 through a transmission device, enabling the rotating assembly 18 to better adapt to different welding processes and production needs.

[0061] During the operation of the multi-station ultrasonic welding device, all components work together. After the operator places the object to be welded at the pick-up and place station 110, the welding parameters are set through the control box 3. The drive component 112 assists the rotating assembly 18 in rotating the support plate 2 to the appropriate welding station 5. The telescopic component 19 adjusts the height of the support frame 17 and the support plate 2 according to the welding requirements, so that the object to be welded is in the optimal welding position. The welding assembly performs the welding operation under the drive of the drive component 16. After welding is completed, the rotating assembly 18 rotates the welded object back to the pick-up and place station 110, and the operator removes the finished product. Throughout the process, the support feet 14 ensure the stability of the device, the protective net 4 protects the welding area, and all components work together to achieve efficient and precise multi-station ultrasonic welding.
