[0002] In applications such as plastic clips for automotive interior parts, riveting of plastic pillars / sheets, and welding of sound-absorbing cotton, ultrasonic piercing welding machines use ultrasonic welding technology to replace the original glue process. They can weld clips and sound-absorbing cotton on products through multi-head ultrasonic spot welding, and can also perform non-standard customization according to product requirements.
[0003] However, welding operations involve using a mold to fix the target object at an inclined angle. Current issues are significant. Firstly, mold adjustment is inconvenient, requiring operators to expend considerable time and effort adjusting parameters like the mold's tilt angle to meet different welding needs, thus reducing overall welding efficiency. Secondly, mold displacement is common during welding. This displacement alters the position of the target object, leading to significant welding deviations and making it difficult to guarantee weld quality that meets standards such as free scratches, dents, depressions, indentations, ripples, and other defects; no damage or cracks on the outer surface and back; no deformation after welding; and uniform, aesthetically pleasing weld marks. Therefore, this application provides a positioning device for rapid mold replacement in ultrasonic welding. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] The limiting blocks at both ends of one side of the support plate of this utility model are adapted to the inner wall of the welding area of the support component. They play a guiding and positioning role during mold installation, allowing operators to quickly and accurately install the mold to the predetermined position, improving mold installation efficiency and reducing installation deviation. The positioning cylinders are distributed on both sides of the four-sided frame of the support plate, forming a limiting area with the triangular support blocks to surround and limit the outside of the target object to be welded.

The cooperation with the mounting hole further enhances the connection stability between the support plate and the support component, prevents the mold from shifting during welding, and ensures the positioning accuracy of the target object to be welded. The preset angle bearing area of the triangular support block is equipped with an extension plate, which is adapted to the target object to be welded and can provide more comprehensive support for the target object. The support strips set on each side of every two triangular support blocks can connect adjacent triangular support blocks into a stable whole, disperse the pressure of the target object on the triangular support blocks, prevent them from tilting or shifting, and ensure that the target object remains stable during the welding process.
[0019] The counteracting action of the telescopic components can effectively resist the vibration generated during the welding process, keeping the support plate stable in the vertical direction; the mounting holes provide accurate positioning and fixing points for the telescopic components, forming a stable connection structure, better dispersing the force generated by welding, and ensuring the stability and reliability of the entire positioning device.
[0020] The adjustment component can control the support plate to move back and forth, left and right, and adjust the angle within the welding area of the support component. It can fine-tune the support plate to a specific position and angle according to the shape, size and welding requirements of different objects to be welded, so that the object is accurately within the working range of the ultrasonic welding head, thus improving the adaptability of the device to different welding needs.
[0021] When it is necessary to change to a different target object to be welded, the support plate can be easily disassembled by controlling the retraction of the telescopic component through the control box. Then, the mold components can be adjusted and repositioned according to the characteristics of the new target object, realizing rapid mold replacement, reducing equipment downtime, and improving overall work efficiency. The precise control of the ultrasonic welding head and telescopic component by the control box avoids errors caused by manual operation, enabling the entire positioning device to complete ultrasonic welding work more efficiently and accurately, thereby improving welding quality and work efficiency.

[0032] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.
[0033] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0034] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4In applications such as plastic clips for automotive interior parts, riveting of plastic pillars / sheets, and welding of sound-absorbing cotton, ultrasonic piercing welding machines use ultrasonic welding technology to replace the original glue process. They can weld clips and sound-absorbing cotton on products through multi-head ultrasonic spot welding, and can also perform non-standard customization according to product requirements.
[0035] However, during welding operations, the mold 4 is used to fix the target object, and the fixing angle is inclined. The current problems are quite prominent. On the one hand, the adjustment process of the mold 4 is not convenient enough, meaning that operators will spend a lot of time and effort adjusting parameters such as the tilt angle of the mold 4 according to different welding needs, reducing the overall efficiency of the welding work. On the other hand, the mold 4 is prone to displacement during the welding process. Displacement of the mold 4 changes the position of the target object, leading to larger deviations during welding. It is difficult to guarantee that the welding quality meets the standards of no scratches, dents, depressions, indentations, ripples, or other defects in the product appearance; no damage or cracks on the outer surface and back of the product; no deformation after welding; and uniform and aesthetically pleasing weld marks. Based on this, this application provides a positioning device for quick replacement of the ultrasonic welding mold 4, including a support component 1 for support, a welding area on the inner side of the support component 1, a movable ultrasonic welding head 2 on the inner side of the welding area, and a mold 4 for supporting the target object located below the ultrasonic welding head 2.
[0036] The mold 4 includes a support plate 42. The support plate 42 has a limiting block 45 for positioning on its outer periphery. The support plate 42 has one or more positioning holes that are equally spaced on its body. Positioning components are installed at the positioning holes to support the target object to be welded.
[0037] The positioning component includes one or more triangular support blocks 43 arranged at equal intervals, and one side of the triangular support block 43 is adapted to the positioning hole opened in the plate of the support plate 42.
[0038] The other side of multiple triangular support blocks 43 forms a bearing area at a preset angle, which is used to support the target object to be welded.
[0039] Support component 1 provides support and a stable structural frame, capable of withstanding various forces generated during operation. The inner side of support component 1 defines the welding area, which is the spatial range for ultrasonic welding operations.
[0040] The welding area is located inside the support component 1, and a movable ultrasonic welding head 2 is installed in this area. The ultrasonic welding head 2 performs welding on the target object. The movable design of the ultrasonic welding head 2 allows it to be flexibly adjusted in position according to different welding requirements to align with different parts of the target object.
[0041] The mold 4 is located below the ultrasonic welding head 2 and is used to support the welding target. It includes a support plate 42 and related positioning components. The following is a detailed description of each part of the mold 4:
[0042] The support plate 42 is the main body of the mold 4, providing a foundation for the welding target. Limiting blocks 45 are provided around the outer perimeter of the support plate 42, serving a positioning function. When the mold 4 is installed or replaced, the limiting blocks 45 can cooperate with the support assembly 1 or other related components to ensure that the mold 4 is accurately installed in the predetermined position, preventing lateral displacement of the mold 4 during welding and improving the accuracy and stability of the mold 4 installation.
[0043] The support plate 42 has one or more positioning holes arranged at equal intervals. The function of these positioning holes is to provide installation positions for the positioning components. The equal spacing of the positioning holes makes the installation of the positioning components regular and repeatable, and facilitates flexible adjustment according to the size and shape of different welding targets.
[0044] A positioning assembly is installed at the positioning hole to support the target object being welded. The positioning assembly includes one or more triangular support blocks 43 arranged at equal intervals. One side of the triangular support block 43 is adapted to a positioning hole in the support plate 42, which means that the triangular support block 43 can be accurately installed in the positioning hole through this side and fits tightly with the positioning hole, ensuring the stability of the installation of the triangular support block 43.
[0045] The other side of multiple triangular support blocks 43 forms a bearing area at a preset angle. Different welding targets may require different tilt angles for fixation. By adjusting the number and arrangement of the triangular support blocks 43, the tilt angle of the bearing area can be easily changed to meet the fixation requirements of different welding targets. For example, for welding targets such as plastic clips or sound-absorbing cotton for automotive interior parts with special shapes, the triangular support blocks 43 can be adjusted to form a suitable tilt angle bearing area according to their shape and welding requirements, so that the target can be stably placed on the mold 4 for welding.
[0046] When using this positioning device for ultrasonic welding, the mold 4 is first accurately installed in the predetermined position on the support assembly 1 via the limiting block 45. Then, according to the shape, size, and required tilt angle of the target object, a suitable number of triangular support blocks 43 are selected and installed in the positioning holes of the support plate 42 to form a suitable preset angle bearing area. Next, the target object to be welded is placed on this bearing area. Due to the stable support of the triangular support blocks 43 and the preset angle design, the target object can be accurately positioned and fixed. Afterwards, the ultrasonic welding head 2 is activated, moving it to the welding position of the target object for ultrasonic welding. During the welding process, because the mold 4 is accurately positioned and stably supported by the limiting block 45 and the positioning assembly, displacement of the mold 4 is effectively avoided, welding deviation is reduced, and welding quality is improved. When it is necessary to change to a different welding target object, the triangular support blocks 43 in the positioning assembly can be quickly adjusted or replaced according to the requirements of the new target object, achieving rapid adjustment and positioning of the mold 4. This improves the efficiency of the welding work and effectively solves the problems of inconvenient adjustment and easy displacement leading to large welding deviations in the use of existing ultrasonic welding molds 4, demonstrating good practicality and promotional value.
[0047] Please see Figure 1 , Figure 4 , Figure 5 as well as Figure 6 The positioning component also includes a positioning cylinder 41, which is distributed on both sides of the perimeter of the support plate 42 and forms a limiting area with the triangular support block 43 to surround the target object to be welded.
[0048] An extension plate 44 is installed at the bearing area of the triangular support block 43 at a preset angle. The plate body of the extension plate 44 is adapted to the target object to be welded.
[0049] A support bar 46 is provided on the side of each pair of triangular support blocks 43 that are close to each other. The support bar 46 is used to maintain the stability of the triangular support blocks 43.
[0050] In addition to the triangular support block 43, the positioning assembly also includes a positioning cylinder 41. The positioning cylinder 41 is distributed on both sides of the perimeter of the support plate 42. When the target object to be welded is placed on the preset angle bearing area formed by the triangular support block 43, the positioning cylinder 41 and the triangular support block 43 work together to form a limiting area. This limiting area can surround the target object from the outside. For example, when welding plastic clips for automotive interior parts, after the plastic clip is placed in the bearing area, the positioning cylinder 41 acts as a barrier and limiter around it, preventing the plastic clip from moving outwards due to the force of the ultrasonic welding head 2 or other external forces during the welding process. This ensures the positional stability of the target object during the welding process and further reduces the possibility of welding deviation.
[0051] An extension plate 44 is installed at the bearing area of the triangular support block 43 at a preset angle. Different targets to be welded have different shapes and sizes, and the extension plate 44 is designed to fit the target to be welded. Taking the welding of automotive sound-absorbing cotton as an example, the sound-absorbing cotton may have an irregular shape. The extension plate 44 can be designed and installed according to the specific shape of the sound-absorbing cotton so that it can fully fit the surface of the sound-absorbing cotton. In this way, the extension plate 44 can provide more comprehensive support for the target to be welded, increase the stability of the target placed in the bearing area, and prevent the target from shaking or shifting during the welding process, thereby improving the accuracy and quality of the welding.
[0052] A support strip 46 is provided on the side of each pair of triangular support blocks 43 that are close to each other. During the welding process, the triangular support blocks 43 need to bear the weight of the object to be welded and various forces generated during welding. The support strip 46 enhances the stability of the triangular support blocks 43. For example, when riveting and welding large or heavy automotive interior plastic pillars / sheets, the support strip 46 can connect adjacent triangular support blocks 43, making them form a more stable whole. When the object is placed on the load-bearing area formed by the triangular support blocks 43, the support strip 46 can distribute the pressure of the object on the triangular support blocks 43, preventing the triangular support blocks 43 from tilting or shifting due to uneven force, ensuring that the triangular support blocks 43 can always maintain the preset angle and position, providing stable support for the object to be welded, thereby ensuring the smooth progress of the welding work and the reliability of the welding quality.
[0053] When using this positioning device for ultrasonic welding, first, the mold 4 is accurately installed on the support assembly 1 via the limiting block 45, as described above. Then, the triangular support block 43 is adjusted to form a suitable preset angle bearing area according to the requirements of the target object to be welded. Next, the extension plate 44 is installed at the bearing area of the triangular support block 43, adapting it to the target object to be welded. Then, the target object to be welded is placed on the bearing area formed by the extension plate 44 and the triangular support block 43. At this time, the positioning cylinder 41 surrounds and limits the target object from the outside. During the welding process, the support bar 46 ensures the stability of the triangular support block 43, preventing displacement. The movable ultrasonic welding head 2 is then activated, moving it to the welding position of the target object to complete the ultrasonic welding operation. If a different target object needs to be welded, simply adjust the triangular support block 43, extension plate 44, and other components according to the characteristics of the new target object to quickly reposition and adjust the mold 4, allowing for continued welding work.
[0054] Please see Figure 5 , Figure 6Limiting blocks 45 are provided at both ends of one side of the support plate 42, and the limiting blocks 45 are adapted to the inner wall of the welding area formed by the inner side of the support component 1.
[0055] One or more positioning cylinders 41 are provided on the top of the support plate 42. A telescopic member 3 is provided on the inner side of the positioning cylinder 41. The telescopic member 3 adapts to the positioning cylinder 41 by telescopic contact to maintain the stability of the support plate 42.
[0056] The support component 1 includes a support frame 12, and the top inner side of the support frame 12 has a mounting hole that is adapted to the telescopic component 3.
[0057] Limiting blocks 45 are provided at both ends of one side of the support plate 42. When the mold 4 needs to be installed into the welding area of the support assembly 1, the operator can align the limiting blocks 45 at both ends of one side of the support plate 42 with the inner wall of the welding area, and then smoothly push the support plate 42 into the welding area. Since the limiting blocks 45 are adapted to the inner wall of the welding area, they can guide and position the mold 42 during installation, ensuring that the support plate 42 is accurately installed in the predetermined position. For example, in the actual production of automotive interior plastic clips or sound-absorbing cotton welding, workers can quickly align the limiting blocks 45 on the mold 4 with the inner wall of the welding area, easily completing the initial installation of the mold 4 and improving installation efficiency. Moreover, during the welding process, the limiting blocks 45 can also prevent the support plate 42 from shifting in the horizontal direction, ensuring the overall stability of the mold 4, thereby reducing welding deviations caused by mold 4 displacement.
[0058] One or more positioning cylinders 41 are provided on the top of the support plate 42. These positioning cylinders 41 serve not only to assist in positioning, but also have telescopic components 3 installed inside them. The telescopic components 3 can extend and retract inside the positioning cylinders 41, such as telescopic cylinders / electric telescopic rods, and the extension and retraction of the telescopic components 3 are adapted to the positioning cylinders 41.
[0059] After the support plate 42 is installed in the welding area of the support assembly 1, the telescopic component 3 begins to function. The telescopic component 3 engages with the positioning cylinder 41 through its own extension and retraction, thereby maintaining the stability of the support plate 42. Specifically, when the telescopic component 3 extends, it can contact other parts of the support assembly 1 and generate a certain amount of resistance. This resistance can fix the support plate 42 in the vertical direction, preventing it from swaying up and down during welding. For example, during ultrasonic welding, the vibrations generated during the welding process may affect the support plate 42, and the resistance of the telescopic component 3 can effectively resist this vibration, keeping the support plate 42 stable and providing a stable support platform for the welding target.
[0060] The support assembly 1 mainly consists of a support frame 12. A mounting hole is provided on the top inner side of the support frame 12. After the support plate 42 is installed in the welding area, the telescopic component 3 extends upward and inserts into the mounting hole on the top inner side of the support frame 12. The mounting hole provides an accurate positioning and fixing point for the telescopic component 3, further enhancing its fixing effect on the support plate 42. After the telescopic component 3 is inserted into the mounting hole, a more stable connection structure is formed, allowing the support plate 42 to be tightly integrated with the support assembly 1. During welding, this stable connection structure better disperses the forces generated during welding, ensuring the stability and reliability of the entire positioning device. For example, when welding large automotive interior parts, the large forces generated during welding are transmitted to the mounting hole through the telescopic component 3 and then dispersed by the support frame 12, thus preventing the support plate 42 from deforming or shifting due to uneven stress and ensuring welding quality.
[0061] When using this positioning device for ultrasonic welding, firstly, the support plate 42 is aligned with the inner wall of the welding area inside the support assembly 1 via the limiting blocks 45 at both ends on one side. The support plate 42 is then smoothly pushed into the welding area, completing the initial positioning and installation of the mold 4. Next, the telescopic component 3 extends upward inside the positioning cylinder 41 and is inserted into the mounting hole at the top inside the support frame 12, further fixing the support plate 42 to the support assembly 1. At this time, according to the shape, size, and required tilt angle of the target object to be welded, the triangular support block 43 is adjusted to form a suitable preset angle bearing area. The extension plate 44 is installed to adapt to the target object, and the target object to be welded is placed on the bearing area. The positioning cylinder 41 surrounds and limits the target object from the outside, and the support bar 46 ensures the stability of the triangular support block 43. Finally, the movable ultrasonic welding head 2 is activated and moved to the welding position of the target object to perform the ultrasonic welding operation. If it is necessary to change to a different target object to be welded, simply follow the steps above: first retract the telescopic component 3, remove the support plate 42 from the welding area, adjust the mold 4 components according to the characteristics of the new target object, and then reinstall and reposition them to continue the new welding work.
[0062] Please see Figure 1 , Figure 4 , Figure 5 as well as Figure 6 The bottom of the support frame 12 is located at the top of the support plate 42 and is provided with an adjustment component 5, which is used to control the adjustment of the support plate 42 within the welding area set by the support component 1.
[0063] A control box 11 is provided on the outside of the support frame 12. The control box 11 is used to control the ultrasonic welding head 2 and the telescopic component 3 to assist the target object in welding.
[0064] An adjustment component 5 is provided at the bottom of the support frame 12 and at the top of the support plate 42, mainly to control the adjustment of the support plate 42 within the welding area set by the support component 1.
[0065] In actual ultrasonic welding work, different objects to be welded may have different sizes, shapes, and welding requirements. To ensure the accuracy and quality of the welding, the position of the support plate 42 needs to be precisely adjusted. The adjustment component 5 can realize the movement of the support plate 42 within the welding area and the adjustment of its angle. For example, when welding some irregularly shaped plastic clips on automotive interior parts, it may be necessary to fine-tune the support plate 42 to a specific position and angle so that the object to be welded is accurately within the working range of the ultrasonic welding head 2. The adjustment component 5 can be adjusted manually or electrically. If manually operated, the operator can control the movement and angle change of the support plate 42 by rotating the knob or handle on the adjustment component 5; if electrically driven, the operator can input commands through the control panel to allow the adjustment component 5 to automatically complete the adjustment of the support plate 42.
[0066] A control box 11 is provided on the outside of the support frame 12, which is mainly used to control the ultrasonic welding head 2 and the telescopic component 3 to assist the target object in welding.
[0067] The control box 11 integrates various control circuits and programs, allowing operators to control the ultrasonic welding head 2 and the telescopic component 3 via the control panel on the control box 11. For the ultrasonic welding head 2, the control box 11 can control its on / off state, power level, welding time, and other parameters. For example, when welding automotive interior parts of different materials and thicknesses, the power and welding time of the ultrasonic welding head 2 need to be adjusted to achieve the best welding effect. The operator simply inputs the corresponding parameter values on the control box 11's control panel, and the control box 11 will transmit the instructions to the ultrasonic welding head 2, causing it to operate according to the set parameters.
[0068] The control box 11 can control the telescopic component 3's extension and retraction. After the support plate 42 is installed in the welding area, the control box 11 can issue a command to extend the telescopic component 3 and insert it into the mounting hole on the top inner side of the support frame 12, thus fixing the support plate 42 to the support assembly 1. When it is necessary to replace the mold 4 or perform maintenance on the device, the control box 11 can control the telescopic component 3 to retract, facilitating the disassembly of the support plate 42. Through the control box 11's control of the ultrasonic welding head 2 and the telescopic component 3, the entire positioning device can complete the ultrasonic welding work more efficiently and accurately, improving welding quality and work efficiency.
[0069] When using this positioning device for ultrasonic welding, the operator first retracts the telescopic component 3 via the control box 11. Then, the support plate 42 is aligned with the inner wall of the welding area inside the support assembly 1 via the limiting blocks 45 at both ends on one side, and the support plate 42 is smoothly pushed into the welding area. Next, the operator issues a command via the control box 11 to extend the telescopic component 3 and insert it into the mounting hole at the top inside the support frame 12, thus fixing the support plate 42 to the support assembly 1. Afterward, depending on the specific situation of the object to be welded, the operator uses the adjustment component 5 to precisely adjust the position and angle of the support plate 42 within the welding area, placing the object in the optimal welding position. Then, based on factors such as the material and thickness of the object, the operator sets parameters such as the power and welding time of the ultrasonic welding head 2 on the operation panel of the control box 11, places the object to be welded on the bearing area composed of the triangular support block 43, the extension plate 44, etc., and positions and stabilizes it using the positioning cylinder 41 and the support bar 46. Finally, the operator starts the ultrasonic welding head 2 on the control box 11 to begin the welding work. After welding a target object is completed, if it is necessary to change to a different target object to be welded, the operator can follow the above steps to control the telescopic component 3, the adjustment component 5 and the ultrasonic welding head 2 through the control box 11 to complete the adjustment of the mold 4 and the new welding work.
[0070] By adjusting the settings of component 5 and control box 11 and their corresponding workflows, the positioning device for quick replacement of ultrasonic welding mold 4 can better adapt to different welding needs, improve the flexibility and practicality of the device, and further ensure the quality and efficiency of ultrasonic welding.
