Description

Technical Field

[0001] This utility model relates to the field of satellite antenna welding technology, and in particular to an automatic satellite antenna welding mechanism. Background Technology

[0002] In the field of satellite antenna manufacturing, welding quality plays a decisive role in the performance of satellite antennas. Traditional satellite antenna welding methods mostly rely on manual operation, which is not only inefficient but also requires extremely high levels of skill and experience from the welders. Prolonged manual work can easily lead to fatigue, resulting in inconsistent welding quality, such as incomplete welds and missing welds, which seriously affect the signal reception and transmission performance of the satellite antenna.

[0003] In addition, some solutions that use automated welding equipment have simple welding mechanism designs and lack precise positioning and flexible posture adjustment functions.

[0004] 1) When dealing with satellite antennas with complex shapes, it is difficult to achieve all-around, high-precision welding. For example, for antenna components with special curved surfaces or irregular structures.

[0005] 2) Existing welding equipment cannot precisely control the position and angle of the welding torch, resulting in a large number of welding blind spots during the welding process. This requires manual secondary welding, which increases production costs and introduces new safety hazards, such as fires or electric shocks caused by improper operation during the welding process.

[0006] 3) Traditional welding equipment lacks versatility and flexibility when dealing with the welding needs of satellite antennas of different specifications. It often requires large-scale modification or even replacement of the equipment, which further reduces production efficiency and increases enterprise costs. Utility Model Content

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-4 As shown, this utility model provides as follows Figure 1 As shown, the automatic satellite antenna welding mechanism of this embodiment includes: two supports 1, and a cross sliding mechanism 2 is fixedly connected to the top of the two supports 1; the cross sliding mechanism 2 includes a first crossbeam 201, a rack 202 is fixedly connected to the top of the first crossbeam 201, and first limiting sliding strips 203 are fixedly installed on both sides of the first crossbeam 201. A first gear 204 meshes with the outer wall of the rack 202. The output end of a first motor 205 is fixedly connected to the outer surface of the first gear 204. A first mounting plate 207 is fixedly connected to the outer surface of the first motor 205. A first sliding seat 208 is fixedly connected to the bottom of the first mounting plate 207. The opposite sides of the first sliding seat 208 are slidably connected to the two first limiting sliding strips 203 respectively. A second crossbeam 209 is fixedly connected to the bottom of the first mounting plate 207. Second limiting sliding strips 210 are fixedly connected to both sides of the second crossbeam 209. A lead screw 211 is movably inserted into the bottom of the second crossbeam 209. A second motor 212 is fixedly connected to the output end of the lead screw 211.

[0026] The overall effect of Embodiment 1 is that, in Embodiment 1, the design of the cross sliding mechanism 2, with the rack 202 on the first crossbeam 201 meshing with the first gear 204 and driven by the first motor 205, allows the first mounting plate 207 to move precisely laterally along the first limiting sliding bar 203, ensuring the positional adjustment accuracy of the welding mechanism in the horizontal direction. Meanwhile, the lead screw 211 at the bottom of the second crossbeam 209, driven by the second motor 212, can achieve vertical displacement adjustment. This cross-shaped sliding and adjustment structure gives the welding mechanism flexible and precise positioning capabilities in a two-dimensional plane, enabling it to move quickly and accurately to the satellite antenna to be welded position, greatly improving the preparation efficiency before welding and laying a solid foundation for subsequent precise welding operations.

[0027] Example 2: A telescopic rotating mechanism 3 is provided on the outer wall of the lead screw 211. The telescopic rotating mechanism 3 includes a second slide 301, a second mounting plate 302 is fixedly connected to the bottom of the second slide 301, a third motor 303 is fixedly connected to the outer surface of the second mounting plate 302, a second gear 304 is fixedly connected to the output end of the third motor 303, a transmission column 305 is fixedly connected to the bottom of the second mounting plate 302, a rotating shaft is fixedly connected to one end of the transmission column 305, a third gear 306 is rotatably connected to the outer wall of the rotating shaft, two telescopic rods 307 are fixedly connected to the outer surface of the third gear 306, an electric push rod 308 is fixedly connected to the outer surface of the rotating shaft, a mounting disc 309 is fixedly connected to one end of the two telescopic rods 307 and the output end of the electric push rod 308, the outer wall of the lead screw 211 and the inner wall of the second slide 301 are threadedly connected, the outer walls of the two second limiting sliding strips 210 and the inner wall of the second slide 301 are slidably connected, and the bottom of the mounting disc 309 and the top of the mounting base 401 are fixedly connected.

[0028] The overall effect of Embodiment 2 is that the telescopic rotation mechanism 3 in Embodiment 2 greatly expands the flexibility of welding operations. Under the synergistic action of the lead screw 211 and the second limiting sliding bar 210, the second slide block 301 can achieve stable lifting and horizontal fine adjustment. The third motor 303 drives the second gear 304, which can drive the transmission column 305 and the connected rotating shaft to rotate, thereby causing the third gear 306 and the telescopic rod 307 to rotate together. At the same time, the electric push rod 308 can control the extension and retraction of the telescopic rod 307 and adjust the position and posture of the mounting disc 309. This mechanism allows the welding device to not only move flexibly in space, but also to make fine adjustments to the angle and position of the welding torch according to welding requirements. It can easily handle complex curved surface welding or welding tasks in special positions, significantly improving the adaptability and accuracy of welding.

[0029] Example 3: As Figures 1-4As shown, a welding device 4 is provided at the bottom of the mounting disc 309. The welding device 4 includes a mounting base 401. A fourth motor 402 is fixedly connected to the bottom of the mounting base 401. A transmission arm 403 is fixedly connected to the output end of the fourth motor 402. A fifth motor 404 is fixedly connected to the outer surface of the transmission arm 403. A welding torch 405 is fixedly connected to the output end of the fifth motor 404. The bottom of the first crossbeam 201 and the top of the two supports 1 are fixedly connected.

[0030] The overall effect of Embodiment 3 is as follows: the fourth motor 402 drives the transmission arm 403 to rotate, which can flexibly adjust the welding angle of the welding torch 405 to meet the requirements of different welding positions and weld shapes; the fifth motor 404 directly drives the welding torch 405, which can precisely control the welding speed and force to ensure the stability of welding quality; the mounting base 401 firmly connects the various components to ensure the stability of the entire device during the welding process, effectively reducing welding defects caused by shaking or displacement. Combined with the precise positioning and flexible adjustment functions provided by the mechanism in the first two embodiments, this welding device can perform high-quality welding of satellite antennas, improve welding efficiency and product quality, and meet the stringent requirements of high-precision welding of satellite antennas.

[0031] Working Principle: After the automatic satellite antenna welding mechanism is activated, the cross sliding mechanism 2 first performs the positioning work. The operator inputs a command to the control system based on the satellite antenna's welding position information. The first motor 205 then starts, and its output shaft drives the first gear 204 to rotate. Since the first gear 204 meshes with the rack 202, this rotation is converted into the first mounting plate 207 moving laterally along the first limit sliding bar 203, allowing the welding mechanism to initially align with the target position in the horizontal direction. Simultaneously, the second motor 212 starts, driving the lead screw 211 to rotate. The lead screw 211 is threadedly connected to the second slide block 301, thereby driving the second slide block 301 and the entire telescopic rotation mechanism 3 to rise and fall vertically, completing precise positioning in the two-dimensional plane. Once positioning is complete, the welding posture adjustment stage begins. If further adjustment of the angle and position of the welding torch 405 is needed, the third motor 303 operates, and its output shaft drives the second gear 304 to rotate. The second gear 304 drives... The transmission column 305 and the rotating shaft rotate, causing the third gear 306 and the telescopic rod 307 to rotate together, changing the rotation angle of the mounting disc 309. At the same time, the electric push rod 308 can extend or shorten according to actual needs, pushing the telescopic rod 307 to fine-tune the position of the mounting disc 309, ensuring that the welding torch 405 can be aligned with the weld at the optimal angle and position. When the welding operation officially begins, the fourth motor 402 starts, driving the transmission arm 403 to rotate, flexibly adjusting the welding angle of the welding torch 405 to fit different welding positions and weld shapes. The fifth motor 404 directly drives the welding torch 405, precisely controlling the welding speed and force. Throughout the welding process, the mounting base 401 plays a role in firmly connecting the various components, ensuring the stability of the device, and reducing welding defects caused by shaking or displacement. The cross sliding mechanism 2 and the telescopic rotation mechanism 3 work together continuously, precisely adjusting the position and angle of the welding torch 405 in real time according to the welding progress and weld changes, until the satellite antenna welding task is completed.

[0032] The wiring diagrams of the first motor 205, the second motor 212, the third motor 303, the electric actuator 308, the fourth motor 402, the fifth motor 404, and the welding torch 405 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the first motor 205, the second motor 212, the third motor 303, the electric actuator 308, the fourth motor 402, the fifth motor 404, and the welding torch 405 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
