Description

Technical Field

[0001] This utility model relates to the field of ultrasonic processing equipment technology, and in particular to an integrated ultrasonic precision welding and cutting device. Background Technology

[0002] Ultrasonic precision welding, also known as ultrasonic welding, is a high-tech technique for welding thermoplastic products. It uses ultrasonic vibration frequencies to melt and fix two plastic parts together at the welding interface due to frictional heat. Specifically, ultrasonic energy is transmitted between the two parts through the welding head, generating high-speed friction, which causes the joint area to generate high heat and fuse instantly. After the sound waves stop, the welding head is left to stand for a period of time to allow the molten plastic at the joint to solidify, thus forming a sturdy component.

[0003] In traditional plastic product processing, welding and cutting are often two separate processes that require different equipment. This not only increases the cost of equipment purchase and floor space, but also leads to a complicated production process and low production efficiency. In addition, during process transitions, secondary positioning errors of materials can easily occur, affecting the processing accuracy and quality of the products.

[0004] For example, in the traditional processing of plastic products, workers need to place the plastic products on an ultrasonic welding machine for welding. After welding, the semi-finished product is removed from the welding machine and transported to the working area of ​​the laser cutting machine. Then, the workers need to readjust the position and orientation of the semi-finished product and place it on the worktable of the laser cutting machine for cutting. This process is not only time-consuming and labor-intensive, but also prone to positioning errors, which may reduce cutting accuracy and greatly reduce production efficiency. Utility Model Content

[0005] This utility model discloses an integrated ultrasonic precision welding and cutting device, which aims to solve the problem that in the traditional plastic product processing, welding and cutting are often two independent processes that require the use of different equipment. This not only increases the purchase cost and floor space of the equipment, but also leads to a cumbersome production process and low production efficiency. In addition, during the process transition, secondary positioning errors of the material are prone to occur, affecting the processing accuracy and quality of the product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated ultrasonic precision welding and cutting device includes a base. The base has a third motor and two processing tables located inside and on its top outer wall, respectively. The output shaft of the third motor is fixedly connected to a mounting frame. The device also includes: a clamping mechanism located on one side of the processing tables; a welding mechanism located on the top of the mounting frame; and a cutting mechanism located on the top of the mounting frame. The cutting mechanism includes two first mounting frames. A fourth electric telescopic rod is located on the top inner wall of each first mounting frame. A support frame is fixedly connected to the movable end of the fourth electric telescopic rod. A second motor is located on one outer wall of the support frame. A rotating shaft is fixedly connected to the output shaft of the second motor. The rotating shaft is connected to the opposite inner wall of the support frame via a bearing. Two cutters are located on the circumferential outer wall of the rotating shaft, and the two cutters are arranged vertically opposite each other.

[0008] The above technical solution integrates ultrasonic welding and cutting functions, reducing equipment purchase costs and floor space, simplifying the production process, and improving production efficiency. Specifically, the plastic sheet to be processed is placed on the processing table, the power and air supply are connected, and the material is firmly fixed by a clamping mechanism to prevent movement during processing. The third motor is started, driving the mounting bracket to rotate, moving the welding mechanism above the material to be welded. The welding mechanism is then activated, and ultrasonic vibration generates frictional heat at the contact surface of the materials, thereby achieving welding of the plastic sheet with other materials. After welding is completed, the third motor is started again, driving the mounting bracket to rotate. The mounting frame is rotated 90 degrees to move the cutting mechanism above the material to be cut. According to the cutting requirements, the position of the first mounting frame is adjusted by the second electric telescopic rod to align the cutter with the kerf. The fourth electric telescopic rod is activated to lower the cutter to a suitable height. The second motor is started to drive the rotating shaft to rotate, causing the cutter to rotate 180 degrees so that one of the cutters is directly above the plastic sheet and cuts the plastic sheet. After cutting, all motors and the ultrasonic generator are turned off. Wait for the equipment to stop running, release the clamping mechanism, and take out the processed product. This setup avoids wear and tear when a single cutter cuts, extending the service life of the entire cutting component.

[0009] In a preferred embodiment, the welding mechanism includes two second mounting frames. The top inner wall of the second mounting frame is provided with a third electric telescopic rod. The movable end of the third electric telescopic rod is fixedly connected to a welding head. One outer wall of the second mounting frame is provided with a connecting plate. The top outer wall of the connecting plate is provided with a first sleeve. The inner wall of the first sleeve is slidably connected with a first limiting rod. One end of the first limiting rod is fixedly connected to the welding head.

[0010] In this solution, when the ultrasonic generator produces a high-frequency electrical signal, it is converted into high-frequency mechanical vibration by the transducer. The amplitude is amplified by the amplitude transformer and transmitted to the welding head. The welding head contacts the plastic plate, causing the molecules on the contact surface of the plastic plate to quickly generate heat through friction. When the temperature reaches the melting point of the plastic, the molecular chains diffuse and entangle with each other, achieving a firm connection after cooling. By controlling the extension and retraction of the third electric telescopic rod, the position of the welding head in the vertical direction can be precisely adjusted. When dealing with plastic plates of different thicknesses, the contact pressure and distance between the welding head and the plastic plate can be quickly adjusted to ensure the welding effect. For example, for thicker plastic plates, the third electric telescopic rod can be appropriately extended so that the welding head can apply sufficient pressure for welding.

[0011] In a preferred embodiment, the clamping mechanism includes two first electric telescopic rods located inside the base. A connecting frame is fixedly connected to the movable end of each first electric telescopic rod. Four second mounting cylinders are provided on the top outer wall of the base. Second limiting rods are slidably connected to the inner walls of the four second mounting cylinders. One end of each second limiting rod is fixedly connected to the bottom outer wall of the connecting frame. The first electric telescopic rod is located between two adjacent second mounting cylinders. A first motor is provided on one side of the outer wall of the connecting frame, and a connecting rod is provided on the opposite side of the inner wall of the connecting frame. The output shaft of the first motor is fixedly connected to one end of the connecting rod. Clamping plates are fixedly connected to the outer circumference of the connecting rod near both ends.

[0012] In this solution, before the plastic sheet is placed on the processing table, the movable end of the first electric telescopic rod drives the connecting frame and the clamping plate to extend upward. After the plastic sheet is placed on the processing table, the connecting frame moves along the direction of the second limit rod under the drive of the first electric telescopic rod. At the same time, the output shaft of the first motor drives the connecting rod to rotate 90 degrees in the direction of the pointer, thereby rotating the vertically upward clamping plate to a state parallel to the processing table. As the movable end of the first electric telescopic rod moves downward, the clamping plate performs the clamping operation on the upper surface of the plastic sheet.

[0013] As described above, an integrated ultrasonic precision welding and cutting device includes a base. The base has a third motor and two processing tables on its interior and top outer wall, respectively. The output shaft of the third motor is fixedly connected to a mounting frame. The device also includes: a clamping mechanism located on one side of the processing table; a welding mechanism located on the top of the mounting frame; and a cutting mechanism located on the top of the mounting frame. The cutting mechanism includes two first mounting frames. A fourth electric telescopic rod is provided on the top inner wall of each first mounting frame. A support frame is fixedly connected to the movable end of the fourth electric telescopic rod. A second motor is provided on one outer wall of the support frame. A rotating shaft is fixedly connected to the output shaft of the second motor. The rotating shaft is connected to the opposite inner wall of the support frame via a bearing. Two cutters are provided on the circumferential outer wall of the rotating shaft, and the two cutters are arranged vertically opposite each other. This integrated ultrasonic precision welding and cutting device integrates ultrasonic welding and cutting functions, reducing equipment purchase costs and floor space, simplifying the production process, and improving production efficiency.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The ultrasonic precision welding and cutting integrated equipment disclosed in this utility model is mainly used in the traditional plastic product processing, where welding and cutting are often two independent processes that require different equipment. This not only increases the purchase cost and floor space of the equipment, but also leads to a complicated production process and low production efficiency. In addition, during the process transition, secondary positioning errors of the material are prone to occur, affecting the processing accuracy and quality of the product.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 An integrated ultrasonic precision welding and cutting device includes a base 1. The base 1 has a third motor 18 and two processing tables 2 respectively located inside and on its top outer wall. The output shaft of the third motor 18 is fixedly connected to a mounting frame 8. The device also includes: a clamping mechanism located on one side of the processing table 2; a welding mechanism located on the top of the mounting frame 8; and a cutting mechanism located on the top of the mounting frame 8. The cutting mechanism includes two first mounting frames 9. The top inner wall of the first mounting frame 9 has a fourth electric telescopic rod 14. The movable end of the fourth electric telescopic rod 14 is fixedly connected to a support frame 15. A second motor 16 is located on one outer wall of the support frame 15. The output shaft of the second motor 16 is fixedly connected to a rotating shaft. The rotating shaft is connected to the opposite inner wall of the support frame 15 via a bearing. Two cutters 17 are located on the circumferential outer wall of the rotating shaft, arranged vertically opposite each other.

[0024] The top outer wall of the processing table 2 has a slit 6.

[0025] In the specific implementation process, the top outer wall of the mounting frame 8 is provided with a mounting groove and two fixing grooves. The inner wall of the mounting groove is provided with two second electric telescopic rods 11. The movable end of the second electric telescopic rod 11 is fixedly connected to one side outer wall of the first mounting frame 9. The first mounting frame 9 is slidably connected to the inner wall of the mounting groove. This design provides a stable guiding effect for the first mounting frame 9. During the cutting process, even if it is subjected to the reaction force generated by the interaction between the cutter 17 and the plastic plate, the first mounting frame 9 can slide smoothly in the mounting groove without shaking or deviating, thereby ensuring the straightness and accuracy of the cut. For example, when cutting long straight lines, stable sliding can prevent the cut lines from bending or wavy, thus improving the cutting quality.

[0026] Specifically, the plastic sheet to be processed is placed on the processing table 2, the power and air supply are connected, and the material is firmly fixed by the clamping mechanism to prevent the plastic sheet from moving during processing. The third motor 18 is started, driving the mounting frame 8 to rotate, so that the welding mechanism moves above the material to be welded. The welding mechanism is then started, and ultrasonic vibration generates frictional heat on the contact surface of the material, thereby achieving the welding of the plastic sheet with other materials. After welding is completed, the third motor 18 is started again, driving the mounting frame 8 to rotate 90 degrees, so that the cutting mechanism moves above the material to be cut. According to the cutting requirements, the position of the first mounting frame 9 is adjusted by the second electric telescopic rod 11, so that the cutter 17... Align the cut slit 6, activate the fourth electric telescopic rod 14 to lower the cutter 17 to a suitable height, activate the second motor 16 to drive the rotating shaft to rotate, causing the cutter 17 to rotate 180 degrees, so that one of the cutters 17 is directly above the plastic sheet and cuts the plastic sheet. After cutting, turn off all motors and the ultrasonic generator, wait for the equipment to stop running, release the clamping mechanism, and take out the processed product. This setup avoids wear and tear when a single cutter 17 is cutting, extending the service life of the entire cutting component. This device integrates ultrasonic welding and cutting functions, reducing equipment purchase costs and floor space, simplifying the production process, and improving production efficiency.

[0027] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the welding mechanism includes two second mounting frames 10. The top inner wall of the second mounting frame 10 is provided with a third electric telescopic rod 12. The movable end of the third electric telescopic rod 12 is fixedly connected to a welding head 13. One outer wall of the second mounting frame 10 is provided with a connecting plate. The top outer wall of the connecting plate is provided with a first sleeve. The inner wall of the first sleeve is slidably connected with a first limiting rod. One end of the first limiting rod is fixedly connected to the welding head 13.

[0028] The inner wall of the fixed groove is equipped with a fourth motor 19. The output shaft of the fourth motor 19 is fixedly connected to a threaded rod 20. One end of the threaded rod 20 is threadedly connected to the outer wall of the second mounting frame 10. The second mounting frame 10 is slidably connected to the inner wall of the fixed groove. When the fourth motor 19 is started, it will drive the threaded rod 20 to rotate. Due to the threaded connection between the threaded rod 20 and the second mounting frame 10, the second mounting frame 10 will slide horizontally in the fixed groove, thereby realizing the fine adjustment of the position of the welding head 13 in the horizontal direction. This allows the equipment to flexibly cope with the welding requirements of different positions on the plastic plate within a certain size range, improving the flexibility and adaptability of welding.

[0029] Specifically, when the ultrasonic generator generates a high-frequency electrical signal, it is converted into a high-frequency mechanical vibration by the transducer. The amplitude is amplified by the amplitude transformer and transmitted to the welding head 13. The welding head 13 contacts the plastic plate, causing the molecules on the contact surface of the plastic plate to generate heat through rapid friction. When the temperature reaches the melting point of the plastic, the molecular chains diffuse and entangle with each other. After cooling, a firm connection is achieved. By controlling the extension and retraction of the third electric telescopic rod 12, the position of the welding head 13 in the vertical direction can be precisely adjusted. When facing plastic plates of different thicknesses, the contact pressure and distance between the welding head 13 and the plastic plate can be quickly adjusted to ensure the welding effect. For example, for thicker plastic plates, the third electric telescopic rod 12 can be appropriately extended so that the welding head 13 can apply sufficient pressure for welding.

[0030] Reference Figure 1 , Figure 3 and Figure 6 In a preferred embodiment, the clamping mechanism includes two first electric telescopic rods 3, which are located inside the base 1. The movable end of the first electric telescopic rod 3 is fixedly connected to a connecting frame 4. The top outer wall of the base 1 is provided with four second mounting cylinders. The inner walls of the four second mounting cylinders are slidably connected with second limiting rods. One end of the second limiting rod is fixedly connected to the bottom outer wall of the connecting frame 4. The first electric telescopic rod 3 is located between two adjacent second mounting cylinders. One side outer wall of the connecting frame 4 is provided with a first motor 5. The opposite side inner wall of the connecting frame 4 is provided with a connecting rod 21. The output shaft of the first motor 5 is fixedly connected to one end of the connecting rod 21. Clamping plates 7 are fixedly connected to the outer circumference of the connecting rod 21 near both ends.

[0031] The mounting frame 8 has four equally spaced support columns on its bottom outer wall, and the base 1 has a limiting groove on its top outer wall. The four support columns are slidably connected to the inner wall of the limiting groove. This multi-point support structure can evenly distribute the weight of the mounting frame 8 and the welding, cutting and other mechanisms installed on it to the four support columns, avoiding structural deformation or damage caused by excessive force at a single point. For example, during equipment operation, when the welding mechanism applies a large pressure to the plastic plate, the four support columns can jointly bear this pressure, ensuring that the mounting frame 8 remains stable.

[0032] Specifically, before the plastic sheet is placed on the processing table 2, the movable end of the first electric telescopic rod 3 drives the connecting frame 4 and the clamping plate 7 to extend upward. After the plastic sheet is placed on the processing table 2, under the drive of the first electric telescopic rod 3, the connecting frame 4 moves along the direction of the second limit rod. At the same time, the output shaft of the first motor 5 drives the connecting rod 21 to rotate 90 degrees in the direction of the pointer, thereby rotating the vertically upward clamping plate 7 to a state parallel to the processing table 2. As the movable end of the first electric telescopic rod 3 moves downward, the clamping plate 7 performs the clamping operation on the upper surface of the plastic sheet.

[0033] Working Principle: During operation, place the plastic sheet to be processed on the processing table 2, connect the power and air supply, and secure the material firmly using the clamping mechanism to prevent movement during processing. Start the third motor 18 to drive the mounting frame 8 to rotate, moving the welding mechanism above the material's welding position. The welding mechanism then activates, using ultrasonic vibration to generate frictional heat at the material's contact surface, thus achieving welding between the plastic sheet and other materials. After welding, start the third motor 18 again to drive the mounting frame 8 to rotate 90 degrees, moving the cutting mechanism above the material's cutting position. Adjust the position of the first mounting frame 9 using the second electric telescopic rod 11 according to the cutting requirements, aligning the cutter 17 with the kerf 6. Start the fourth electric telescopic rod 14 to lower the cutter 17 to a suitable height. Start the second motor 16 to drive the rotating shaft to rotate, causing the cutter 17 to rotate 180 degrees, so that one of the cutters 17 faces the top of the plastic sheet and cuts it. After cutting, turn off all motors and the ultrasonic generator, wait for the equipment to stop running, release the clamping mechanism, and remove the processed product.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
