Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic assembly and welding, and in particular to an ultrasonic assembly machine. Background Technology

[0002] Ultrasonic assembly utilizes the high-frequency vibrations of ultrasound to generate intense friction and heat between molecules at the connection points of parts, achieving molecular-level fusion. Taking the ultrasonic assembly of plastic parts as an example, this fusion method significantly increases the strength of the connection, often reaching strength comparable to the material of the part itself, ensuring that the assembled product is less prone to loosening or breakage during use. Traditional assembly methods often suffer from low efficiency and inconsistent assembly quality. For instance, in the assembly of some small electronic devices, multiple components need to be precisely fixed together. Manual assembly is not only slow but also struggles to guarantee consistent assembly precision for each product. Ultrasonic welding, as a highly efficient and reliable connection method, is increasingly being widely used across various industries.

[0003] However, existing ultrasonic assembly equipment still has room for improvement in terms of fixture design and ease of operation. For example, the fixtures are not very adaptable to parts of different sizes, and it is difficult to quickly adjust the clamping space to meet diverse production needs. Utility Model Content

[0004] This invention aims to at least partially solve one of the problems in the related art. Therefore, one objective of this invention is to provide an ultrasonic assembly machine that improves the adaptability and ease of operation of the clamps.

[0005] An ultrasonic assembly machine includes a worktable, an ultrasonic welding machine, and a clamping mechanism. The clamping mechanism is disposed on the worktable, and the ultrasonic welding machine is located above the clamping mechanism. The clamping mechanism includes a clamping member and a moving component. The clamping member includes a first clamping part and a second clamping part. The first clamping part is fixedly connected to the worktable, and the second clamping part is connected to the moving component and movable on the worktable. The moving component moves to move the second clamping part closer to or away from the first clamping part. The first clamping part and the second clamping part are connected to form a welding cavity, which is located below the welding head of the ultrasonic welding machine.

[0006] Furthermore, the moving component includes a guide rail and a slider, the guide rail is fixed to the worktable, the slider is slidably connected to the guide rail, and the second clamping part is connected to the slider.

[0007] Furthermore, the moving component also includes a connecting seat, a connecting shaft, and a handle. The connecting seat is fixedly connected to the worktable and located on one side of the guide rail. One end of the handle is rotatably connected to the connecting seat. One end of the connecting shaft is connected to the slider, and the other end is connected to the handle.

[0008] Furthermore, the welding cavity is arc-shaped.

[0009] Furthermore, a positioning block is provided on the edge of one of the opposing surfaces of the first clamping part and the second clamping part, and a positioning groove is provided on the other side. When the first clamping part is connected to the second clamping part, the positioning block is inserted into the positioning groove.

[0010] Furthermore, there are multiple positioning blocks and multiple positioning slots. Multiple positioning blocks are spaced apart along the edge of the first clamping part or the second clamping part, and multiple positioning slots are spaced apart along the edge of the second clamping part or the first clamping part. One positioning block is inserted into one positioning slot.

[0011] Furthermore, buffer pads are provided on the opposite sides of both the first clamping part and the second clamping part.

[0012] Furthermore, the clamping mechanism also includes a fixed base, which is fixedly connected to the worktable, and the first clamping part is mounted on the fixed base.

[0013] Furthermore, the clamping mechanism also includes a fastener, one end of which is fixedly connected to the worktable, and the other end of which abuts against the edge of the first clamping part.

[0014] Furthermore, the clamping component is made of aluminum alloy, engineering plastic, or stainless steel.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art:

[0016] The welding cavity formed by the connection of the first and second clamping parts in this application is located below the welding head of the ultrasonic welding machine, ensuring that the parts to be welded are in the optimal position during welding. During ultrasonic welding, the ultrasonic energy can be concentrated on the welding area, reducing energy loss, improving welding quality, avoiding problems such as weak welding and incomplete welding caused by welding position deviation, and improving the quality stability of assembled products.

[0017] The movable component of the clamping mechanism moves the second clamping part closer to or further away from the first clamping part. This adjustable clamping design allows the ultrasonic assembly machine to adapt to parts of various sizes and specifications. For example, when producing different models of plastic shells, whether the product is slightly larger or smaller, it can be securely clamped by adjusting the spacing of the clamping parts, meeting diverse production needs and overcoming the shortcomings of existing clamps in adapting to parts of different sizes, thus improving the versatility of the equipment. Furthermore, the movement of the second clamping part via the movable component is simpler and faster than the traditional method of manually fixing parts. Operators only need to control the movable component to quickly complete the clamping of parts, saving clamping time, improving production efficiency, reducing labor costs, and making the ultrasonic assembly process more efficient and orderly.

[0030] like Figure 1 - Figure 3 As shown, the ultrasonic assembly machine 1 provided in this application includes a worktable 10, an ultrasonic welding machine 30, and a clamping mechanism 50. The clamping mechanism 50 is disposed on the worktable 10, and the ultrasonic welding machine 30 is located above the clamping mechanism 50. The clamping mechanism 50 includes a clamping member 51 and a moving component 53. The clamping member 51 includes a first clamping part 511 and a second clamping part 513. The first clamping part 511 is fixedly connected to the worktable 10, and the second clamping part 513 is connected to the moving component 53 and moves on the worktable 10. The moving component 53 moves to drive the second clamping part 513 closer to or away from the first clamping part 511. The first clamping part 511 and the second clamping part 513 are connected to form a welding cavity 515, which is located below the welding head of the ultrasonic welding machine 30.

[0031] The ultrasonic assembly machine consists of a worktable 10, an ultrasonic welding machine 30, and a clamping mechanism 50. The worktable 10 provides support and a stable foundation for the entire equipment; the ultrasonic welding machine 30, as the core welding component, is responsible for generating ultrasonic waves to perform the welding operation; the clamping mechanism 50 is used to fix the parts to be welded. The clamping element 51 in the clamping mechanism 50 is divided into a fixed first clamping part 511 and a movable second clamping part 513. The second clamping part 513 is moved by a moving component 53, allowing for flexible adjustment of the clamping space to accommodate parts of different sizes. The welding cavity 515 is located below the welding head of the ultrasonic welding machine 30, ensuring the accuracy of the welding position and enabling the ultrasonic energy to effectively act on the welding area, thus improving welding quality.

[0032] The worktable 10 serves as the fundamental support component of the entire ultrasonic assembly machine, providing a stable mounting platform for other components. Its function is similar to the foundation of a building, ensuring the stability of the ultrasonic welding machine 30 and the clamping mechanism 50 during operation, preventing shaking or displacement from affecting welding accuracy. In actual production environments, a stable worktable 10 ensures that the relative positions of the components remain unchanged during long-term operation, allowing for precise and repeatable welding operations.

[0033] The ultrasonic welding machine 30, located above the clamping mechanism 50, is the core component for ultrasonic assembly. Its main function is to generate ultrasonic waves, using high-frequency vibrations to create intense friction and heat between molecules at the joint of the parts, thereby achieving molecular-level fusion and completing the welding operation. During the welding process, the emitted ultrasonic energy is concentrated on the welding area, determining the quality and effect of the weld. In the welding of plastic parts, the performance of the ultrasonic welding machine 30 directly affects the strength and appearance quality of the welded joint.

[0034] The clamping mechanism 50, consisting of a clamping member 51 and a moving assembly 53, is a key component of the ultrasonic assembly machine for clamping parts of different sizes. The first clamping part 511 of the clamping member 51 is fixed to the worktable 10, serving as a reference for positioning. The second clamping part 513 is connected to the moving assembly 53 and can move on the worktable 10. The moving assembly 53 moves the second clamping part closer to or further away from the first clamping part 511, thereby adjusting the clamping space to accommodate parts of different sizes. This design solves the problem of poor adaptability of existing clamps to parts of different sizes, improving the versatility of the equipment. When producing electronic device housings of different specifications, the clamping space can be easily adjusted for clamping.

[0035] The clamping parts 51 (first clamping part 511 and second clamping part 513) work together to form a welding cavity 515. The first clamping part 511 serves as a fixed end, providing stable support for the parts to be welded; the second clamping part 513 is movable and cooperates with the first clamping part 511 to firmly fix the parts within the welding cavity 515. The welding cavity 515 formed by the connection of the two is located below the welding head of the ultrasonic welding machine 30, ensuring that the parts are in the optimal position during welding, guaranteeing that the ultrasonic energy can accurately act on the welding area, and improving the welding quality and stability.

[0036] The moving component 53 is connected to the second clamping part 513, and its main function is to move the second clamping part 513. Through the movement of the moving component 53, the clamping space can be flexibly adjusted, enabling the ultrasonic assembly machine to adapt to parts of various sizes and specifications. The design of the moving component 53 improves the ease of operation, allowing operators to quickly adjust the clamping space and improve production efficiency. If the moving component 53 is motor-driven, automated control can be achieved, further improving production efficiency and clamping accuracy.

[0037] The worktable 10 can be made of high-strength aluminum alloy with internal reinforcing ribs to enhance load-bearing capacity and reduce weight. The surface is anodized to improve wear and corrosion resistance, while also increasing friction to prevent slippage of the clamping mechanism 50. The ultrasonic welding machine 30 is a piezoelectric ultrasonic welding machine equipped with an automatic frequency tracking system that can adjust the frequency in real time to adapt to different welding conditions. Its welding head is made of titanium alloy, which is high in hardness, wear-resistant, and has good ultrasonic wave conduction performance. In the clamping mechanism 50, the first clamping part 511 and the second clamping part 513 of the clamping component 51 adopt a modular design, allowing for the replacement of different clamping modules according to the shape and size of different parts. In addition to the basic guide rail 531 and slider 532, the moving component 53 incorporates a ball screw drive structure to achieve more precise displacement control.

[0038] Furthermore, the moving component 53 includes a guide rail 531 and a slider 532. The guide rail 531 is fixed to the worktable 10, the slider 532 is slidably connected to the guide rail 531, and the second clamping part 513 is connected to the slider 532.

[0039] The structure employing guide rail 531 and slider 532 makes the movement of the second clamping part 513 smoother and more precise. Guide rail 531 provides stable guidance for the movement of slider 532, ensuring that the second clamping part 513 moves along a predetermined trajectory when approaching or moving away from the first clamping part 511, avoiding deviation. This not only improves the accuracy of clamping components but also facilitates repeated positioning, ensuring consistency in each clamping operation, thereby enhancing the stability of ultrasonic welding and product quality. Furthermore, this structure is simple and reliable, facilitating maintenance and component replacement.

[0040] The guide rail 531 is a high-precision linear guide rail 531. Multiple rolling elements, such as steel balls or rollers, are installed between the internal slider 532 and the guide rail 531 to reduce frictional resistance and improve motion accuracy. The cross-sectional shape of the guide rail 531 can be designed as rectangular or dovetail. The rectangular guide rail 531 has a high load-bearing capacity and is suitable for clamping heavier components; the dovetail guide rail 531 has high guiding accuracy and is suitable for applications requiring high precision.

[0041] The slider 532 is manufactured using a one-piece casting process and is made of ductile iron, which offers excellent strength and shock absorption. Multiple mounting holes are provided on the slider 532 for easy connection to the second clamping part 513, and the positions of these holes are fine-tunable to accommodate different clamping requirements. Wear-resistant sheets made of polytetrafluoroethylene are adhered to the surfaces of the slider 532 that contact the guide rail 531 to further reduce the coefficient of friction and extend service life.

[0042] Furthermore, the moving component 53 also includes a connecting seat 533, a connecting shaft 534, and a handle 535. The connecting seat 533 is fixedly connected to the worktable 10 and located on one side of the guide rail 531. One end of the handle 535 is rotatably connected to the connecting seat 533. One end of the connecting shaft 534 is connected to the slider 532, and the other end is connected to the handle 535.

[0043] The connecting seat 533, connecting shaft 534, and handle 535 constitute a manual operating mechanism. By rotating the handle 535, the operator utilizes the lever principle to move the connecting shaft 534, thereby causing the slider 532 to slide on the guide rail 531, thus moving the second clamping part 513. This manual operation method is simple and intuitive, requiring no complex electric drive system, thus reducing equipment costs. Furthermore, the operator can flexibly and precisely adjust the position of the second clamping part 513 according to actual needs, which is highly advantageous in applications requiring high operational precision.

[0044] The connector 533 is made of cast steel and machined to ensure its precision. The connector 533 is L-shaped, with one end fixed to the worktable 10 and the other end used to mount the handle 535 and the connecting shaft 534. This shape effectively saves space and increases the stability of the connector 533. High-strength bolts are used to connect the connector 533 to the worktable 10, and anti-loosening washers are added to prevent the connector 533 from loosening.

[0045] The handle 535 features an ergonomic design with a rubber-coated surface for increased grip comfort and friction. An internal torque adjustment device allows operators to adjust the force required to turn the handle 535 for more precise operation. The connecting shaft 534 is made of high-strength alloy steel and undergoes heat treatment to improve its overall mechanical properties. The connection between the connecting shaft 534, the slider 532, and the handle 535 utilizes a universal joint, allowing for a certain degree of angular deviation and preventing operational issues caused by installation errors or minor offsets during movement.

[0046] Furthermore, the welding cavity 515 has an arc shape.

[0047] The arc-shaped welding cavity 515 can better focus ultrasonic energy. During ultrasonic welding, the arc-shaped structure allows the ultrasonic waves to be distributed more evenly within the welding cavity 515, reducing energy scattering and increasing the energy density of the welding area. This helps to more effectively generate friction and heat at the joint of the components, resulting in a stronger weld. Simultaneously, for components with curved surfaces, the arc-shaped welding cavity 515 can better conform to their shape, improving the adaptability and stability of the weld and ensuring consistent weld quality.

[0048] The arc-shaped design of welding cavity 515 can be customized according to the welding requirements of different components. For circular or arc-shaped components, the radius of the arc of welding cavity 515 can be adjusted according to the curvature of the component to achieve a better fit. A layer of sound-absorbing material, such as polyurethane foam, is added to the inner wall of welding cavity 515 to reduce the reflection and scattering of ultrasonic waves in the cavity and improve the utilization rate of welding energy.

[0049] The size of the welding cavity 515 can be achieved by providing adjustable baffles on the first clamping part 511 and the second clamping part 513. The baffles can slide along the edge of the clamping part and be fixed in different positions by bolts, thereby changing the size of the welding cavity 515 to accommodate parts of different sizes.

[0050] Furthermore, a positioning block 5111 is provided on one edge of the opposite side surface of the first clamping part 511 and the second clamping part 513, and a positioning groove 5131 is provided on the other side. When the first clamping part 511 is connected to the second clamping part 513, the positioning block 5111 is inserted into the positioning groove 5131.

[0051] The cooperation between the positioning block 5111 and the positioning groove 5131 provides a precise positioning method for the first clamping part 511 and the second clamping part 513. When clamping parts, the positioning block 5111 inserts into the positioning groove 5131, which can quickly and accurately determine the relative position of the two clamping parts, ensuring the consistency of the welding cavity 515. This not only improves clamping accuracy, but also ensures that the parts are always in the same position during multiple clamping processes, reducing welding defects caused by clamping position deviations and improving product yield. At the same time, this positioning method also helps to improve the clamping efficiency of operators.

[0052] The positioning block 5111 is shaped like a frustum of a cone, and the positioning groove 5131 is a matching conical hole. This design achieves better centering and improves positioning accuracy. Several annular grooves are provided on the conical surface of the positioning block 5111, and rubber sealing rings are installed in the grooves. When the positioning block 5111 is inserted into the positioning groove 5131, the sealing rings can play a sealing and buffering role, further improving the stability of positioning.

[0053] In addition to mechanical positioning, a magnetic positioning function is added. Permanent magnets are embedded in the positioning block 5111 and the positioning groove 5131 respectively, and magnetic attraction is used to assist positioning. Especially when the parts are light or the positioning accuracy requirements are extremely high, it can effectively prevent the parts from shifting during the welding process.

[0054] Furthermore, there are multiple positioning blocks 5111 and multiple positioning grooves 5131. Multiple positioning blocks 5111 are spaced apart along the edge of the first clamping part 511 or the second clamping part 513, and multiple positioning grooves 5131 are spaced apart along the edge of the second clamping part 513 or the first clamping part 511. One positioning block 5111 is inserted into one positioning groove 5131.

[0055] The spaced arrangement of multiple positioning blocks 5111 and positioning grooves 5131 further improves the accuracy and stability of positioning. Multiple positioning points better limit the relative displacement of the first clamping part 511 and the second clamping part 513, ensuring the positional accuracy of the welding cavity 515 even under external vibration or large clamping force. Moreover, this design can adapt to parts of different shapes and sizes. By selecting different positions of the positioning blocks 5111 and positioning grooves 5131, the clamping method can be flexibly adjusted, improving the adaptability of the ultrasonic assembly machine to diverse production processes.

[0056] The multiple positioning blocks 5111 and positioning grooves 5131 are arranged in a matrix, not only along the edge of the clamping part, but also evenly distributed on the surface of the clamping part, forming multiple positioning points to further improve the accuracy and stability of positioning. The positioning blocks 5111 and positioning grooves 5131 at different positions can be designed with different sizes and depths according to the shape and stress conditions of the parts to adapt to different clamping requirements.

[0057] Furthermore, buffer pads are provided on the opposite sides of the first clamping part 511 and the second clamping part 513.

[0058] The buffer pad can be made of flexible materials such as rubber. When clamping parts, it can play a buffering role to avoid damage to the parts and also improve the stability of clamping.

[0059] Buffer pads are typically made of flexible materials such as rubber. When clamping parts, they act as a buffer, preventing damage from excessive clamping force, especially for parts with easily scratched surfaces or brittle textures. Simultaneously, buffer pads increase the friction between the clamping part and the part, improving clamping stability and preventing displacement of parts during welding, thus ensuring weld quality. Furthermore, buffer pads can absorb some of the vibrations generated during ultrasonic welding, reducing the impact on other components of the equipment.

[0060] Besides rubber, cushioning pads can also be made of silicone or polyurethane elastomers. Silicone has good high-temperature resistance and aging resistance, making it suitable for welding in high-temperature environments; polyurethane elastomers have high strength and elasticity, providing better cushioning. The surface of the cushioning pad can be designed in a wavy or mesh pattern to increase the contact area with components and improve cushioning and anti-slip performance.

[0061] The cushioning pad is secured using a combination of adhesive and slots. Slots are created on the surface of the clamping part, and the edges of the cushioning pad are inserted into these slots. Strong adhesive is used to ensure that the cushioning pad will not fall off during use.

[0062] Furthermore, the clamping mechanism 50 also includes a fixed base 55, which is fixedly connected to the worktable 10, and the first clamping part 511 is mounted on the fixed base 55.

[0063] The mounting base 55 securely mounts the first clamping part 511 onto the worktable 10, enhancing its stability. Compared to directly fixing the first clamping part 511 to the worktable 10, the mounting base 55 provides more reliable support, reducing the risk of loosening due to vibration or external impact. This helps ensure the positional accuracy of the welding cavity 515 and improves the quality of ultrasonic welding. Furthermore, the design of the mounting base 55 facilitates the installation and removal of the first clamping part 511, making equipment maintenance and upgrades easier.

[0064] The mounting base 55 adopts a frame structure, consisting of multiple reinforcing beams and support plates, which improves its load-bearing capacity and stability. Multiple mounting holes are provided at the bottom of the mounting base 55, which is fixed to the worktable 10 by anchor bolts. The positions of the mounting holes are adjustable for easy installation and adjustment. A shock-absorbing rubber pad is provided at the connection between the mounting base 55 and the first clamping part 511 to reduce the transmission of vibration during welding to the first clamping part 511.

[0065] The mounting base 55 is provided with a cable management slot, which is used to organize and fix the cables connecting the first clamping part 511 and other components, so as to avoid cable tangling and damage, and at the same time make the overall layout of the equipment neater.

[0066] Furthermore, the clamping mechanism 50 also includes a fastener 57, one end of which is fixedly connected to the worktable 10, and the other end abuts against the edge of the first clamping part 511.

[0067] Fastener 57 further secures the position of the first clamping part 511. One end is fixed to the worktable 10, and the other end abuts against the edge of the first clamping part 511, preventing displacement during operation. This is crucial for ensuring the stability of the welding cavity 515, guaranteeing accurate positioning of components during each welding operation and improving the consistency of welding quality. Furthermore, the fastener 57 can be adjusted according to actual needs, facilitating fine-tuning of the first clamping part 511 to adapt to different working requirements.

[0068] Fastener 57 can be a combination of high-strength bolts and nuts. The bolts are hex socket head cap bolts, which are easy to tighten with tools and provide a large preload. The nuts are lock nuts, such as nylon self-locking nuts or flange nuts, to prevent loosening under vibration. Resilient washers are installed at the ends of fastener 57 to further enhance the anti-loosening effect.

[0069] One end of the fastener 57 is threaded onto the workbench 10, and the other end is equipped with an adjustment knob. The operator can easily adjust the clamping force of the fastener 57 on the first clamping part 511 by rotating the adjustment knob to ensure that the first clamping part 511 is firmly fixed.

[0070] Furthermore, the clamping component 51 is made of aluminum alloy, engineering plastic, or stainless steel.

[0071] Aluminum alloys are lightweight, high-strength, and corrosion-resistant. Using aluminum alloys to make the clamping component 51 ensures its structural strength while reducing the overall weight of the equipment, facilitating the operation of the moving component 53. Engineering plastics are low-cost, have good insulation and a certain degree of flexibility, making them suitable for clamping soft parts with high surface quality requirements, while also reducing equipment costs. Stainless steel has the advantages of high strength and high corrosion resistance, making it suitable for ultrasonic assembly machines operating in harsh environments, or for applications requiring high strength and corrosion resistance in the clamping component 51, ensuring its service life and performance stability.

[0072] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
