Description
Technical Field
[0001] This utility model relates to the technical field of welding equipment, and in particular to a vertical high-frequency welding machine. Background Technology
[0002] With the rapid development of 5G communication technology, 5G transmitters play a crucial role in communication networks as key equipment. During their manufacturing process, after the connector installation and welding are completed, the upper and lower covers need to be welded and fixed to ensure the device's sealing and structural stability. Typically, the upper and lower covers, or their connecting parts, are made of plastic and are thermally bonded by heating and cooling. This hot-melt welding process requires equipment that can accurately position and firmly clamp the upper and lower covers, while providing uniform heating and appropriate pressing pressure to ensure weld quality. However, existing welding equipment has shortcomings in terms of ease of operation, positioning accuracy, and welding efficiency. For example, traditional equipment often requires complex clamping steps, making it difficult to quickly complete the positioning and installation of the fixture, thus affecting production efficiency. Simultaneously, due to the precise welding positions of the upper and lower covers, existing equipment is prone to positional misalignment or uneven pressure during heating and pressing, leading to unstable weld quality. Furthermore, existing equipment lacks flexibility in the alignment and fixing methods of the upper and lower covers, making it difficult to adapt to the welding requirements of products with different specifications. Therefore, there is an urgent need for welding equipment that can achieve rapid installation and positioning, precise control of the welding process, and improved production efficiency in order to solve the above-mentioned technical problems and meet the high-precision requirements in the manufacturing of 5G transmitters. Utility Model Content
[0003] The purpose of this invention is to provide a vertical high-frequency welding machine to overcome the shortcomings of the existing technology.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A vertical high-frequency welding machine includes a frame, a base plate, a fixed fixture, a lifting system, a moving fixture, and a design separating water and electrical circuits. The frame serves as the main supporting structure, with a base plate mounted on top. A pair of directional strips are installed on the base plate. These directional strips extend along the surface of the base plate to guide the fixed fixture into a preset position, simplifying the installation process. A pad is embedded inside the fixed fixture, and four lifting cylinders are arranged below the pad, located at the four inner corners of the fixed fixture. The piston rods of the lifting cylinders extend upwards through through holes in the pad and, during operation, lift the lower cover upwards, applying pressure to complete the thermal fusion and fixing connection. Furthermore, a high-frequency heating strip is embedded and fixedly installed within the fixed fixture to heat the connection between the upper and lower covers. The high-frequency heating strip is connected to an external power source via wires, and its heating power and temperature range can be adjusted according to actual needs. The fixture has through holes that correspond to the positioning holes on the substrate. A first positioning pin passes through the fixture and is inserted into the positioning hole on the substrate, enabling quick installation and precise positioning of the fixture. In particular, the outer diameter of the first positioning pin matches the inner diameter of the through hole and the positioning hole to ensure that the fixture will not loosen or shift after installation.
[0006] Furthermore, the lifting system includes a lifting cylinder and a lifting module. The lifting cylinder is installed inside the frame, and its piston rod extends upward and is fixedly connected to the lifting module, used to control the vertical movement of the lifting module relative to the substrate. A pair of fastening strips are fixedly installed at the bottom of the lifting module to abut against the edge of the moving fixture, ensuring that the moving fixture slides into the predetermined position. The top of the moving fixture has an upwardly recessed placement cavity for placing the upper cover of the transmitter. A vacuum hole is provided in the placement cavity, which is connected to an external vacuum pump, and can generate negative pressure to adsorb the upper cover, ensuring that the upper cover remains stable during the welding process. A through hole is opened on the moving fixture, corresponding to the positioning hole on the lifting module. A second positioning pin is inserted into the positioning hole of the lifting module through the through hole of the moving fixture to complete the quick installation and positioning of the moving fixture. In particular, the end of the second positioning pin has an outwardly protruding locking post, the inner wall of the positioning hole of the lifting module has an inwardly recessed sliding groove and an inner rotation groove, and the through hole of the moving fixture also has a sliding groove. During installation, the second locating pin slides into the slot and then rotates to engage with the inner groove, achieving a stable connection of the moving fixture. The dimensions of the sliding slot and the inner groove match the shape of the locking pin, ensuring high stability of the moving fixture after installation.
[0007] Furthermore, the water and electrical copper pipes are designed separately. The water pipes are used to cool the high-frequency heating element, preventing overheating due to prolonged heating; the electrical copper pipes are used to transmit current, powering the high-frequency heating element. The water and electrical copper pipes are separated by insulating material to prevent mutual interference, ensuring operational safety and ease of maintenance. The water pipe interfaces connect to an external cooling water source, and the electrical copper pipe interfaces connect to an external power source; both connections use threaded sealing structures to prevent water or electrical leakage.
[0008] The working principle of this utility model is as follows: S1: In the initial state, the fixed fixture is fixed to the base plate by the first positioning pin, and the movable fixture is fixed to the lifting module by the second positioning pin. The lower cover is placed in the receiving groove of the fixed fixture, and the upper cover is placed in the placement cavity of the movable fixture, and fixed by vacuum adsorption. S2: The high-frequency heating strip heats the connection between the upper and lower covers. The heating time is set according to the material characteristics until the heat fusion temperature is reached. S3: The lifting cylinder drives the lifting module to move downward, so that the movable fixture is close to the fixed fixture. The piston rod of the lifting cylinder lifts upward, moving the lower cover upward and pressing it against the upper cover to complete the heat fusion welding fixation. S4: After welding is completed, the lifting cylinder drives the lifting module to reset and remove the welded workpiece.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] The design of the first and second locating pins enables rapid installation and precise positioning of both fixed and moving fixtures, significantly improving operational efficiency. The combined use of high-frequency heating strips and lifting cylinders ensures the stability and consistency of the welding process. The design of directional strips, snap-fit strips, and vacuum adsorption simplifies the installation and fixing process of the upper and lower covers. The separate design of the water and electrical copper pipes effectively avoids safety hazards and facilitates equipment maintenance and repair.
[0011] In summary, this utility model provides a high-efficiency, stable and easy-to-operate vertical high-frequency welding machine, which is particularly suitable for hot-melt welding and fixing of the upper and lower covers of 5G transmitters and has broad application prospects.

[0022] As attached Figure 1As shown, the vertical high-frequency welding machine of this utility model mainly includes a frame, a base plate 8, a fixed fixture 6, a lifting system, a moving fixture 10, and a water and electrical circuit separation design. The frame serves as the main supporting structure of the entire equipment, with the base plate 8 fixedly mounted on its top. A pair of directional strips 4 are provided on the base plate 8. The directional strips 4 extend along the surface of the base plate, providing guidance for the sliding of the fixed fixture 6, thereby ensuring that the fixed fixture 6 can quickly and accurately slide into the preset position. A pad 5 is embedded inside the fixed fixture 6, and four lifting cylinders 2 are arranged below the pad 5, located at the four corners of the inner side of the fixed fixture. The piston rod of the lifting cylinder 2 extends upward through the through hole in the pad 5, and lifts the lower cover upward during operation, applying pressure to complete the thermal fusion fixing connection.

The high-frequency heating strip 3 is connected to an external power source via wires, and its heating power and temperature range can be adjusted according to actual needs. The fixture 6 has a through hole that corresponds to the positioning hole on the substrate 8.

The outer diameter of the first positioning pin 7 matches the inner diameter of the through hole and the positioning hole to ensure that the fixture will not loosen or shift after installation.
[0023] As attached Figure 2 As shown, the lifting system includes a lifting cylinder 1 and a lifting module 9. The lifting cylinder 1 is installed inside the frame, and its piston rod extends upward and is fixedly connected to the lifting module 9, controlling the vertical movement of the lifting module relative to the base plate 8. A pair of fastening strips 12 are fixedly provided at the bottom of the lifting module 9 for abutting against the edge of the moving fixture 10, ensuring that the moving fixture slides into the predetermined position. The top of the moving fixture 10 has an upwardly recessed placement cavity for placing the upper cover of the transmitter. A vacuum hole is provided in the placement cavity, which is connected to an external vacuum pump, and can generate negative pressure to adsorb the upper cover, ensuring that the upper cover remains stable during the welding process. The moving fixture 10 has a through hole, which corresponds to the positioning hole on the lifting module 9. A second positioning pin 11 is inserted into the positioning hole of the lifting module through the through hole of the moving fixture, completing the rapid installation and positioning of the moving fixture. The second positioning pin 11 has an outwardly protruding locking post at its end. The inner wall of the positioning hole of the lifting module 9 has an inwardly recessed sliding groove and an inner rotating groove. The through hole of the moving fixture 10 also has a sliding groove. During installation, the locking post of the second positioning pin 11 slides into the sliding groove and then rotates to engage with the inner rotating groove, achieving a stable connection of the moving fixture. The dimensions of the sliding groove and the inner rotating groove match the shape of the locking post, ensuring high stability of the moving fixture after installation.
[0024] As attached Figure 3As shown, the water and electrical copper pipes are designed separately. The water pipes are used to cool the high-frequency heating strip 3, preventing overheating due to prolonged heating. The electrical copper pipes are used to transmit current, powering the high-frequency heating strip. The water and electrical copper pipes are separated by insulating material to prevent mutual interference, ensuring operational safety and ease of maintenance. The water pipe interfaces connect to the external cooling water source, and the electrical copper pipe interfaces connect to the external power supply. Both connections use threaded sealing structures to prevent water or electrical leakage.
[0025] The equipment operates as follows: S1 In the initial state, the fixed fixture 6 is fixed to the base plate 8 by the first positioning pin 7, and the movable fixture 10 is fixed to the lifting module 9 by the second positioning pin 11. The lower cover is placed in the receiving groove of the fixed fixture 6, and the upper cover is placed in the placement cavity of the movable fixture 10, and fixed by vacuum adsorption. S2 The high-frequency heating strip 3 heats the connection between the upper and lower covers. The heating time is set according to the material characteristics until the heat fusion temperature is reached. S3 The lifting cylinder 1 drives the lifting module 9 to move downward, so that the movable fixture 10 is close to the fixed fixture 6. The piston rod of the lifting cylinder 2 lifts upward, moving the lower cover upward and pressing it against the upper cover to complete the heat fusion welding fixation. S4 After welding is completed, the lifting cylinder 1 drives the lifting module 9 to reset and remove the welded workpiece.
[0026] In practical applications, the vertical high-frequency welding machine of this invention exhibits significant technical advantages. Firstly, the design of the first positioning pin 7 and the second positioning pin 11 enables rapid installation and precise positioning of the fixed fixture 6 and the moving fixture 10, significantly improving operational efficiency. Secondly, the coordinated use of the high-frequency heating strip 3 and the lifting cylinder 2 ensures the stability and consistency of the welding process. Thirdly, the design of the directional strip 4, the fastening strip 12, and the vacuum adsorption simplifies the installation and fixing process of the upper and lower covers, reducing operational difficulty. Finally, the separate design of the water and electrical copper pipes effectively avoids safety hazards and facilitates equipment maintenance and repair.
[0027] Furthermore, the vertical high-frequency welding machine of this invention demonstrates excellent performance in actual production. For example, in the manufacturing process of 5G transmitters, the welding quality of the upper and lower covers directly affects the sealing performance and service life of the equipment. Traditional welding methods often require manual adjustment of the positions of the upper and lower covers, which is not only time-consuming and labor-intensive but also difficult to guarantee welding consistency. This invention, through its highly automated design, can complete the welding of a large number of workpieces in a short time while ensuring stable welding quality. The high-frequency heating strip 3 has high heating efficiency, reaching the required hot-melt temperature in a short time, thus shortening the entire welding cycle. The piston rod of the lifting cylinder 2, through precise pressure control, tightly presses the lower and upper covers together, ensuring a smooth and flat welding surface and avoiding problems such as bubbles or cracks that may occur in traditional welding methods.
[0028] In summary, this utility model's vertical high-frequency welding machine achieves efficient welding of the upper and lower covers of 5G transmitters through optimized structural design and operation procedures. Each component of the equipment has been meticulously designed to ensure ease of operation, welding stability, and equipment safety. In practical applications, this equipment can significantly improve production efficiency, reduce labor costs, and enhance product quality and consistency, demonstrating broad application prospects.
