Description

Technical Field

[0001] This utility model relates to the field of rolling equipment technology, specifically a rolling equipment for tin-plated conductors. Background Technology

[0002] In today's rapidly developing electronics and electrical industries, tin-plated conductors, as a key basic material, play an indispensable role in numerous fields. From precision chip manufacturing to massive power transmission systems and ubiquitous consumer electronics, tin-plated conductors are indispensable. With the rapid advancement of technology, these applications place increasingly stringent requirements on the quality and performance of tin-plated conductors.

[0003] Traditional tin-plating conductor processing methods have gradually revealed numerous problems in meeting these high requirements. Early, simple mechanical rolling techniques, while able to initially alter the conductor's shape, were inadequate in terms of dimensional control. The resulting tin-plated conductors exhibited uneven thickness and large width deviations, failing to meet the standards of high-precision applications. For example, in chip manufacturing, even minute dimensional deviations can lead to performance degradation or even chip failure, resulting in persistently high scrap rates and significantly increased production costs.

[0004] Furthermore, traditional rolling equipment cannot apply uniform and stable pressure to the conductor during processing. This not only leads to problems such as tin plating peeling and wear, reducing the conductor's corrosion resistance, but also causes uneven internal structure, affecting its electrical properties and significantly compromising the stability and accuracy of signal transmission. In fields with extremely high signal quality requirements, such as 5G communication and high-speed data transmission, this performance defect is unacceptable.

[0005] Furthermore, in today's increasingly automated production environment, traditional tin-plated conductor rolling equipment is complex to operate, requiring a large amount of manpower for frequent debugging and monitoring. It struggles to efficiently coordinate with modern automated production lines, severely hindering production efficiency and failing to meet the demands of large-scale production. Therefore, developing a tin-plated conductor rolling device that can solve these problems is urgently needed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1 As shown in the figure, an embodiment of this utility model discloses a rolling device for tin-plated conductors, including a cabinet 1 and feet 2 installed at the four corners of the bottom of the cabinet 1. The feet 2 are threaded and serve to support the entire rolling device. The height of the device can be adjusted via the feet 2 to adapt to different placement surfaces, ensuring the stability of the device and preventing uneven placement surfaces from affecting rolling accuracy.

[0027] like Figure 1 As shown, the gantry 3 is fixedly installed on top of the cabinet 1. This connection method enables the gantry 3 to form a stable frame structure for the entire device. Its function is to provide a reliable support foundation for subsequent installation of components such as the main hydraulic cylinder 4, ensuring that these components are fixed in position during operation and maintaining the overall stability of the device.

[0028] like Figure 1-2 As shown, the main hydraulic cylinder 4 is fixedly connected to the gantry 3, and the output end of the main hydraulic cylinder 4 passes through the gantry 3 and is fixedly connected to the positioning plate 5. This connection method ensures that the main hydraulic cylinder 4 can be stably installed on the gantry 3. The main hydraulic cylinder 4 serves as a power source, and through the extension and retraction of its output end, it drives the positioning plate 5 to move up and down, providing the main pressure for the rolling of the tin-plated conductor and controlling the rolling force and depth.

[0029] like Figure 1-2 As shown, the horizontal plate 6 is installed at the bottom of the positioning plate 5, and the positioning plate 5 is perpendicular to the horizontal plate 6. This vertical installation structure enhances the structural stability of the positioning plate 5, while providing an installation position for the limiting block 7, helping the positioning plate 5 maintain balance during movement and preventing it from wobbling.

[0030] like Figure 1-2As shown, the limiting block 7 is fixedly connected to both sides of the horizontal plate 6, and the limiting block 7 is slidably connected to the positioning column 8, which is fixedly installed on the gantry frame 3. The sliding connection structure between the limiting block 7 and the positioning column 8 restricts the movement trajectory of the positioning plate 5, allowing it to move up and down only along the direction of the positioning column 8, thereby ensuring the accuracy and stability of the positioning plate 5 during movement and improving the precision of the rolling operation.

[0031] like Figure 1-2 As shown, the auxiliary hydraulic cylinder 9 is mounted on the positioning plate 5, and its output end passes through the positioning plate 5 and is fixedly connected to the upper pressure plate 10. This connection method allows the auxiliary hydraulic cylinder 9 to further precisely control the movement of the upper pressure plate 10 based on the positioning plate 5. The auxiliary hydraulic cylinder 9, in conjunction with the main hydraulic cylinder 4, applies more precise pressure to the tin-plated conductor, meeting the requirements of different rolling processes and improving the quality and precision of rolling.

[0032] like Figure 2-3 As shown, the servo motor 11 is mounted on the cabinet 1, and the output end of the servo motor 11 is fixedly connected to the threaded rod 12. The threaded rod 12 is rotatably connected to the top of the cabinet 1 through a bearing seat. This connection structure enables the servo motor 11 to drive the threaded rod 12 to rotate, converting the rotational motion of the motor into the rotation of the threaded rod 12, providing a power source for the movement of the lower pressure plate 14.

[0033] like Figure 2-3 As shown, the threaded block 13 is threadedly connected to the threaded rod 12, and the lower pressure plate 14 is fixedly connected above the threaded block 13. When the threaded rod 12 rotates, the threaded block 13 moves axially along the threaded rod 12, thereby driving the lower pressure plate 14 to move synchronously. This structure precisely controls the position of the lower pressure plate 14 through the rotation of the threaded rod 12, and cooperates with the upper pressure plate 10 to realize the rolling processing of tin-plated conductors of different thicknesses, ensuring the dimensional accuracy of the rolling.

[0034] like Figure 2-3 As shown, slider 15 is fixedly connected to the side wall of lower pressure plate 14, and slider 15 is slidably connected to slide rail 16, which is fixedly installed on cabinet 1. This connection method ensures the stability of lower pressure plate 14 during movement, prevents lower pressure plate 14 from shifting in the horizontal direction, ensures that lower pressure plate 14 moves parallel to upper pressure plate 10, and makes the tin-plated conductor subjected to uniform force during rolling, thereby improving the rolling quality.

[0035] During the rolling operation of the tin-plated conductor (flat plate), the servo motor 11 is first turned on, and its output end drives the threaded rod 12 to rotate. Since the threaded rod 12 is rotatably connected to the top of the cabinet 1 through the bearing seat, the rotation of the threaded rod 12 will cause the threaded block 13 to displace on its surface, and the lower pressure plate 14 fixedly connected above the threaded block 13 will slide parallel accordingly. At this time, the operator places the tin-plated conductor flat plate on the lower pressure plate 14. The slider 15 fixedly connected to the side wall of the lower pressure plate 14 engages and slides on the slide rail 16 fixedly installed on the cabinet 1, ensuring that the lower pressure plate 14 moves smoothly. After the loading is completed, the main hydraulic cylinder 4 is started. The main hydraulic cylinder 4 pushes the positioning plate 5 to move downward along the positioning column 8 fixedly installed on the gantry 3. The limit blocks 7 on both sides of the horizontal plate 6 at the bottom of the positioning plate 5 slide on the positioning column 8 to ensure that the positioning plate 5 descends stably. At the same time, the two auxiliary hydraulic cylinders 9 installed on the positioning plate 5 move downward accordingly. Then, the auxiliary hydraulic cylinder 9 is activated, and its output end pushes the upper pressure plate 10 downward to press the tin-plated conductor flat plate. The upper pressure plate 10 and the lower pressure plate 14 cooperate to roll the tin-plated conductor. After rolling is completed, the auxiliary hydraulic cylinder 9 is first controlled to retract, causing the upper pressure plate 10 to rise. Then, the main hydraulic cylinder 4 is controlled to retract, causing the positioning plate 5 and related components to rise. Finally, the servo motor 11 is started to reverse, driving the lower pressure plate 14 to slide parallel to a convenient material-receiving position. The operator then unloads the material, thus completing the entire rolling operation process of the tin-plated conductor flat plate.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
