Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding equipment technology, and in particular to an irregular workpiece fixture, an ultrasonic welding tooling platform, equipment and system. Background Technology

[0002] Ultrasonic welding is a highly efficient and environmentally friendly joining process that uses high-frequency vibration energy to locally melt and bond materials. It is widely used in the processing of plastics, metals, and composite materials. Advantages of ultrasonic welding include no need for flux, a small heat-affected zone, and high welding speed, making it suitable for fields such as precision electronics, automobiles, and medical devices.

[0003] Traditional ultrasonic welding fixtures are mostly designed with fixed dimensions, making it difficult to adapt to the needs of different workpieces. They also lack high-precision limiting structures, easily leading to welding misalignment. Existing adjustable fixtures are complex to adjust and have low locking efficiency, while custom fixtures for irregularly shaped workpieces are expensive. Furthermore, under high-frequency vibration, ordinary fixtures struggle to maintain stability, affecting welding quality. Moreover, existing tooling fixtures are mostly limited to simple unidirectional clamping, making it difficult to maintain stability under high-frequency ultrasonic vibration, while customized molds for irregularly shaped workpieces further increase processing costs. Therefore, there is an urgent need for a new type of fixture that is highly versatile, easy to adjust, and highly stable. Utility Model Content

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] To address the drawback of existing traditional fixtures lacking precise limiting structures, which leads to displacement of irregularly shaped workpieces during welding and affects welding accuracy, the inventors initially customized fixtures to fit the shapes of different irregularly shaped workpieces. However, these fixtures lacked adjustability, resulting in low adaptability and high customization costs. Therefore, the inventors attempted to separate the limiting mechanism into an independently adjustable one, using this mechanism to constrain the position of the irregularly shaped workpiece. However, during experiments, the inventors found that a small number of limiting mechanisms (limiting blocks, limiting screws, etc.) were insufficient to limit the position of irregularly shaped workpieces with varying shapes. Therefore, the inventors further divided the limiting mechanism into multiple sufficiently small units, placing them closely together to surround and limit the irregularly shaped workpiece. By reducing the size of the limiting mechanism and increasing its number, the inventors were able to fix different irregularly shaped workpieces effectively, achieving unexpected results.

[0036] This utility model provides a fixture for irregularly shaped workpieces, as shown in the following embodiment. Figure 1 and Figure 2 As shown, the irregular workpiece fixture 1 may include: a support plate 11, two cover plates 12, and several limiting posts 13; wherein, the support plate 11 is provided with a groove 111, and the irregular workpiece 2 to be welded and several limiting posts 13 are located in the groove 111; several limiting posts 13 are distributed on both sides of the irregular workpiece 2 to be welded, and the ends of some of the limiting posts 13 abut against the irregular workpiece 2 to be welded to clamp the irregular workpiece 2 to be welded; the two cover plates 12 are located on both sides of the irregular workpiece 2 to be welded, and respectively cover the several limiting posts 13 located on both sides of the irregular workpiece 2 to be welded so that the limiting posts 13 are fixed in the groove 111.

[0037] In this embodiment, the overall structure of the support plate is preferably rectangular. The rectangular structure not only facilitates installation on the moving slide of the linear motion module, but also makes it easier to position the limiting posts. The cover plate in this embodiment is divided into two parts: a main body the same size as the groove, and skirts located on both sides of the main body for easy installation on the support plate. The cover plate can fix the limiting posts in the vertical direction (see reference). Figure 3 The Z-axis direction is relative to the X-axis direction of the first linear motion module 3 and the Y-axis direction of the second linear motion module 4. In this embodiment, the limiting post is a columnar structure limiting post with a small cross-section and a long length. It can be a small iron block. The small cross-section makes the entire limiting post thinner. Multiple limiting posts are closely arranged to abut against multiple areas of the irregular workpiece to be welded. The long length makes it easy to fix all the limiting posts through the cover plate.

[0038] The operation steps of the above-mentioned irregular workpiece fixture in this embodiment are as follows: First, place the irregular workpiece to be welded in the groove of the bearing plate; then, a number of limiting posts abut against both sides of the irregular workpiece to be welded, and the adjacent limiting posts are tightly fitted; finally, use a cover plate to press the limiting posts, so that the limiting posts are fixed and thus the irregular workpiece to be welded is fixed.

[0039] The irregular workpiece fixture provided in this embodiment uses a combination of several limiting posts and cover plates to clamp the irregular workpiece in the groove of the bearing plate. This ensures that the irregular workpiece remains stable during the welding process, which can meet the clamping force requirements and adapt to the shape of different irregular workpieces, thus solving the problem of high cost and poor adaptability of customized fixtures.

[0040] In one embodiment, the ultrasonic welding in this embodiment adopts an lap welding method. Therefore, when welding two workpieces, it is necessary to confine the two workpieces in the groove. In order to achieve the lap joint of the two workpieces, this embodiment further improves the structure of the groove. (Refer to...) Figure 2 As shown, the groove 111 may include a first groove 1111 and a second groove 1112, and there is a depth difference between the first groove 1111 and the second groove 1112; the irregular workpiece 2 to be welded includes a first welding workpiece 21 and a second welding workpiece 22, the first welding workpiece 21 is located in the first groove 1111, the second welding workpiece 22 is located in the second groove 1112, and the first welding workpiece 21 and the second welding workpiece 22 overlap; a portion of the limiting post 13 is located in the first groove 1111 and abuts against the first welding workpiece 21, and a portion of the limiting post 13 is located in the second groove 1112 and abuts against the second welding workpiece 22.

[0041] The groove of the bearing plate provided in this embodiment includes a first groove and a second groove. The first groove and the second groove are integrally formed and connected. There is a depth difference between the first groove and the second groove, and the depth difference between the two grooves is about 1mm. This can meet the overlapping requirements between the irregular workpieces to be welded located in the two grooves.

[0042] In one embodiment, refer to Figure 1 and Figure 2 As shown, the edge of the bearing plate 11 is provided with a plurality of first bolt holes 112 along the thickness direction, and the edges of the two cover plates 12 are provided with a plurality of second bolt holes 121 matching the first bolt holes 112 along the thickness direction. The irregular workpiece fixture 1 may also include a plurality of first bolts 14. The two cover plates 12 are fastened to the bearing plate 11 through the first bolt holes 112, the second bolt holes 121, and the first bolts 14. In this embodiment, the structure of the bolt holes and bolts facilitates the fixing of the cover plates to the bearing plate, and then the limiting post abutting against the irregular workpiece to be welded is fixed by fastening the cover plates, thereby fixing the two sides of the irregular workpiece to be welded and preventing the workpiece from shaking during the welding operation.

[0043] In one embodiment, refer to Figure 2 As shown, the irregular workpiece fixture 1 may further include: a pressure plate 15 and several second bolts 16; the edge of the bearing plate 11 is provided with several third bolt holes 113 communicating with the groove 111 perpendicular to the thickness direction; the pressure plate 15 is located in the groove 111 and abuts against the adjacent limiting post 13, and the second bolts 16 pass through the third bolt holes 113 and abut against the pressure plate 15 to compress the several limiting posts 13. In this embodiment, the pressure plate and the second bolts can fix the limiting posts in another direction (perpendicular to the long axis direction of the limiting posts) and move them in the Y-axis direction during processing (see reference). Figure 3 In this way, the limiting post is stably fixed in both the long axis direction and the direction perpendicular to the long axis direction.

[0044] In one specific embodiment, the pressure plate is divided into two parts, and there is a thickness difference between the two parts along the thickness direction of the pressure plate. In this embodiment... Figure 1 and Figure 2 The thickness difference between the two parts of the pressure plate is not shown in the figure. Those skilled in the art will understand that the thickness difference will not be greater than 1 mm. Therefore, the thickness difference is not as obvious as that of the groove in the figure. This embodiment will not be described in detail here.

[0045] In one embodiment, the irregular workpiece fixture may further include several shims (not shown in the figure) located between the groove and the irregular workpiece to be welded. In this embodiment, adding shims between the groove and the irregular workpiece to be welded can solve the problem of poor stability due to varying thicknesses of the irregular workpieces.

[0046] In one embodiment, the edge of the support plate is marked with graduations (not shown in the figure). Since the support plate in this embodiment is rectangular, graduations can be marked on all four edges. This allows for the calculation of welding dimensions using the graduations, facilitating personnel recording and generating welding operation instructions.

[0047] Based on the same inventive concept, this utility model also provides an ultrasonic welding fixture platform, referring to... Figure 3 and Figure 4 As shown, the ultrasonic welding fixture platform may include: a first linear motion module 3, a second linear motion module 4, and the aforementioned irregular workpiece fixture 1; wherein, the first linear motion module 3 includes a first movable slide 31, and the second linear motion module 4 includes a second movable slide 41; the second linear motion module 4 is mounted on the first movable slide 31, and the irregular workpiece fixture 1 is mounted on the second movable slide 41.

[0048] In this embodiment, the first linear motion module can be called the X-axis linear motion module, and the second linear motion module can be called the Y-axis linear motion module. The first linear motion module drives the second linear motion module and the irregular workpiece fixture to move in the X-axis direction, and the second linear motion module drives the irregular workpiece fixture to move in the Y-axis direction.

[0049] Based on the same inventive concept, this utility model embodiment also provides an ultrasonic welding device, which may include a device frame and the aforementioned ultrasonic welding fixture platform; the ultrasonic welding fixture platform is mounted on the device frame.

[0050] Based on the same inventive concept, this utility model embodiment also provides an ultrasonic welding system, which may include an ultrasonic welding machine, a controller, and the aforementioned ultrasonic welding equipment; the ultrasonic welding machine and the controller may be respectively installed on the ultrasonic welding equipment, and the controller is electrically connected to both the ultrasonic welding machine and the ultrasonic welding equipment, for controlling the ultrasonic welding machine to perform welding operations and controlling the first linear motion module 3 (refer to...) on the ultrasonic welding fixture platform in the ultrasonic welding equipment. Figure 3 (As shown) and / or the second linear motion module 4 drives the irregular workpiece fixture 1 to move.

[0051] The beneficial effects and specific implementation of the ultrasonic welding fixture platform, ultrasonic welding equipment and ultrasonic welding system described in this embodiment can be referred to the relevant description of the irregular workpiece fixture described above, and will not be repeated here.

[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. This disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
