Description

Technical Field

[0001] The present invention relates to the technical field of assembly equipment, and in particular to an automatic assembly device for a satellite antenna and the satellite antenna. Background Art

[0002] Satellite antennas are devices used to send and receive satellite signals. The automatic assembly device for satellite antennas is an intelligent industrial robot that can realize efficient, precise and large-scale production of satellite antennas. There are many types of industrial robots, which are mainly used to replace manual labor to complete the positioning, docking, fastening and other assembly processes of antenna components.

[0003] When producing satellite phone antennas, due to the small size and numerous accessories of the satellite antennas, an assembly turntable becomes an important piece of equipment required for their production. Specifically, multiple mounting positions are set on a rotating turntable for fixing the satellite antenna, and multiple robotic arms with different functions are set around the assembly for loading and unloading the satellite antenna and assembling parts.

The fixing part has its own clamping and fixing device, which reduces the need for additional fixing components in the subsequent process, making it more convenient and practical.

[0005] The existing technology has the following defects:

[0006] Due to the large number of satellite antenna models, the lengths and outer contours of different satellite antennas are different, which may lead to insufficient restraining force of the installation position on the satellite antenna, causing the satellite antenna to slide and offset when assembling accessories. The robotic arm may also have positioning deviation problems due to the different heights of the tops of the satellite antennas. The above situations can be solved by designing multiple sets of corresponding fixtures and control programs, but the fixtures are troublesome to disassemble and assemble, which will affect efficiency, and frequent disassembly and assembly will also affect accuracy. Designing multiple sets of control programs will lead to excessive costs and adaptability problems. Summary of the Invention

[0022] Furthermore, a shielding ring is provided on the outer side of the signal antenna. The cross section of the shielding ring is a right triangle, and the right-angled side of the shielding ring is in contact with the signal antenna.

[0023] Beneficial effects of the present invention:

[0024] 1. By setting up a fixed component and injecting air into multiple air cushions synchronously through the air control component, many air cushions expand synchronously and approach the signal antenna, clamping the signal antenna in the center. Since all air cushions are in a connected state, the internal pressure is balanced, and the expansion of the stressed air cushion in contact with the fixed component is temporarily suspended or stopped, while the air cushion without stress continues to expand until it contacts the signal antenna and is stressed. In this way, all air cushions can fit tightly with the signal antenna, making it adaptable to signal antennas of different shapes. It is also quick and convenient to use and more suitable for current automation equipment.

[0025] 2. By setting up the air control component, when the air supply equipment supplies air for the first time, air enters the air cylinder and pushes the piston block to move a distance. The piston block distributes the air in the air cylinder to various main pipes through the converging cylinder, and finally enters the air cushion, causing the air cushion to initially expand and play a role of pre-fixation. The excess air is discharged through the exhaust pressure valve 2. At this time, the signal antenna remains in a centered vertical state, but is not clamped, which is convenient for pressing the equipment to adjust the height and makes the adjustment process more stable and accurate. Then the air supply equipment supplies air for the second time. At this time, the exhaust pressure valve 2 is blocked by the piston block, and the air has nowhere to be discharged. The pressure in the air cushion increases to clamp the signal antenna. When the signal antenna is completely clamped, the pressure is fixed, and the excess air is discharged from the exhaust pressure valve 1, so that the pressure is always kept stable.

[0026] 3. By setting the regulating component, when loading, the signal antenna is placed above the pallet through the placement hole. When adjusting the height, the pallet can slide on the surface of the mounting frame through the slide to adaptively change the height. During this process, the push rod slides in the sleeve, and the hydraulic oil in the sleeve flows into the oil cylinder through the connecting pipe. When the turntable rotates and the signal antenna enters the assembly area, the lifting rod leaves the gap and is lifted upward by the control ring. The lower piston moves upward to close the connecting pipe. In this way, the sleeve is in a sealed state, and the push rod can no longer move to support the slide and the pallet, thereby lifting the signal antenna, so that it obtains sufficient supporting force and the state is more stable.

[0027] 4. By setting a sealing ring, when the signal antenna is installed, the signal antenna enters the signal interface. When the sealing ring contacts the bottom wall of the signal interface, it is squeezed and deformed. The sealing ring deforms and turns outward to fit the inner wall of the signal interface. In this way, a tightly sealed area is formed at the intersection of the bottom wall and the inner wall of the signal interface. Water or dust in the harsh external environment cannot enter the signal connection between the signal interface and the signal antenna, avoiding poor contact and ensuring smooth signal.

DETAILED DESCRIPTION

[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0050] Example 1

[0051] Reference Figures 1-14, which is the first embodiment of the present invention, provides an automatic assembly device for a satellite antenna, which is used for assembling a signal antenna 9, including an assembly platform 1, a support frame 2 arranged on the top of the assembly platform 1, a turntable 3 arranged on the top of the support frame 2, a mounting base 4 arranged on the top of the turntable 3, two clamps 5 arranged on the side of the mounting base 4 away from the central axis of the turntable 3, a placement hole 6 running through the tops of the two clamps 5, a lifting mechanism 7 arranged at the bottom of the turntable 3, and also includes a fixing component 8 arranged on the clamp 5, the fixing component 8 specifically includes a fixing bar 81 embedded in the inner wall of the placement hole 6, an air cushion 82 arranged on the side of the fixing bar 81 away from the inner wall of the placement hole 6, a main pipe 83 and a branch pipe 84 arranged inside the clamp 5, and an air control component 85 arranged at the bottom of the clamp 5.

[0052] Specifically, the support frame 2 is fixed to the top of the assembly platform 1 by bolts, and the turntable 3 is rotatably connected to the top of the support frame 2. A circle of robotic arms is set around the turntable 3 on the top of the assembly platform 1, and the number of robotic arms is the same as the number of clamps 5. The robotic arms are roughly divided into two categories according to their functions, one for loading and unloading the signal antenna 9, and the other for installing various accessories. The mounting seat 4 is fixed to the turntable 3 by bolts, and the two clamps 5 are slidably installed on the side of the mounting seat 4. A pneumatic device is set in the mounting seat 4 to control the opening and closing of the two clamps 5 by air pressure. The wire 9 passes through the placement hole 6 and falls above the lifting mechanism 7; the inner wall of the placement hole 6 is provided with a groove for installing the fixing strip 81, and the fixing strip 81 is fixed inside by bolts. A channel for implanting the main pipe 83 and the branch pipe 84 is provided in the clamp 5. The fixing strips 81 are distributed in a circular array in the placement hole 6, and the main pipe 83 is distributed in a circular array outside the placement hole 6. The branch pipe 84 connects the air cushion 82 and the main pipe 83. The main pipe 83 is connected to the air control component 85 by a hose. The air control component 85 is connected to the air supply equipment through a hose, and multiple main pipes 83 are connected in the air control component 85.

[0053] By setting up a fixing component 8 and injecting air into multiple air cushions 82 synchronously through the air control component 85, many air cushions 82 expand synchronously and approach the signal antenna 9, clamping the signal antenna 9 in the center. Since all air cushions 82 are in a connected state, the internal pressure is balanced, and the expansion of the stressed air cushion 82 in contact with the fixing component 8 is temporarily suspended or stopped, and the air cushion 82 without stress continues to expand until it contacts the signal antenna 9 and is stressed. In this way, all air cushions 82 can fit tightly with the signal antenna 9, so that it can adapt to signal antennas 9 of different shapes. It is also quick and convenient to use and more suitable for current automation equipment.

[0054] A pressing device is provided on the top of the mounting seat 4. The pressing device is composed of a rotating telescopic rod and a pressing plate. When in use, the telescopic rod will first lift the pressing plate and move it above the placement hole 6. Then the telescopic rod will drive the pressing plate to press down to adjust the height of the signal antenna 9. Finally, the pressing device is reset. In this way, the height of all signal antennas 9 can be kept uniform, avoiding the situation where the robotic arm is positioned incorrectly.

[0055] The air control assembly 85 includes a fixed seat 851 arranged at the bottom of the clamp 5, an air cylinder 852 and a converging cylinder 853 arranged on the inner side of the fixed seat 851, a piston block 854 arranged on the inner side of the air cylinder 852, an air intake pressure valve 855 arranged on the outer side of the converging cylinder 853, and an exhaust pressure valve 1 856 and an exhaust pressure valve 2 857 arranged on the outer side of the air cylinder 852.

[0056] Specifically, three fixing seats 851 are grouped together and concentrically arranged, and fixed to the bottom of the clamp 5 by bolts. The air cylinder 852 is clamped in the two fixing seats 851 of the same group, and the converging cylinder 853 is clamped in one fixing seat 851. One end of the air cylinder 852 is provided with a connecting pipe that penetrates into the converging cylinder 853, and the other end is provided with an air supply connector connected to the air supply equipment. The air supply equipment adopts a two-stage air supply, and the air supply volume is fixed each time. An exhaust connector is provided on the outside of the converging cylinder 853, and the main pipe 83 is connected to the converging cylinder 853. The piston block 854 is slidably installed in the air cylinder 852. The exhaust pressure valve 1 856 and the exhaust pressure valve 2 857 are located between the piston block 854 and the converging cylinder 853. The exhaust pressure valve 2 857 is located between the exhaust pressure valve 1 856 and the piston block 854. The opening pressure of the exhaust pressure valve 2 857 is less than the opening pressure of the exhaust pressure valve 1 856.

[0057] By setting the air control component 85, when the air supply device supplies air for the first time, air enters the air cylinder 852 and pushes the piston block 854 to move a distance. The piston block 854 distributes the air in the air cylinder 852 to the main pipes 83 at various locations through the converging cylinder 853, and finally enters the air cushion 82, so that the air cushion 82 initially expands to play a role of pre-fixation. The excess air is discharged through the exhaust pressure valve 857. At this time, the signal antenna 9 remains in a centered vertical state, but is not clamped, which is convenient for pressing the device for height adjustment and makes the adjustment process more stable and accurate. Then the air supply device supplies air for the second time. At this time, the exhaust pressure valve 857 is blocked by the piston block 854, and the air has nowhere to be discharged. The pressure in the air cushion 82 increases to clamp the signal antenna 9. When the signal antenna 9 is fully clamped, the pressure is fixed, and the excess air is discharged from the exhaust pressure valve 856, so that the pressure is always kept stable.

[0058] Specifically, the air cushions 82 on the surface of the fixing strip 81 are a group, and the number of air cushions 82 in a group is not less than two, so that it can adapt to more complex shapes and have a higher fit with the signal antenna 9.

[0059] Specifically, there are two placement holes 6 and two air control components 85 , and the main pipes 83 surrounding the same placement hole 6 are connected to the same air control component 85 , so that the signal antenna 9 can be evenly stressed.

[0060] Specifically, the cross section of the piston block 854 is in a concave shape, with the concave opening facing the converging cylinder 853 .

[0061] Example 2

[0062] Reference Figures 1-17 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the lifting mechanism 7 specifically includes a mounting frame 71 arranged at the bottom of the turntable 3, a sliding groove 72 and a regulating groove 73 extending through the side of the mounting frame 71, a slide plate 74 and a limit plate 75 respectively arranged on both sides of the mounting frame 71, and a supporting plate 76 arranged on the side of the slide plate 74 away from the mounting frame 71.

[0063] Specifically, the mounting frame 71 is arranged corresponding to the clamp 5 and is fixed to the turntable 3 by bolts. The slide 74 passes through the slide groove 72, the regulating groove 73 and is connected to the limit plate 75. The slide 74 can slide on the surface of the mounting frame 71. The support plate 76 is located directly below the placement hole 6 to support the signal antenna 9. A triangular reinforcement rib is provided under the support plate 76. There are two slide grooves 72, which are distributed on both sides of the regulating groove 73. The length of the regulating groove 73 is greater than the slide groove 72.

[0064] By providing the lifting mechanism 7 , the supporting plate 76 is lifted below the signal antenna 9 , thereby ensuring the stability of the signal antenna 9 when assembling accessories.

[0065] The lifting mechanism 7 also includes a regulating component 77, which specifically includes a sleeve 771 arranged on the inner side of the regulating groove 73, a push rod 772 arranged on the inner side of the sleeve 771, a connecting pipe 773 arranged on the side of the sleeve 771, an oil cylinder 774 arranged at the end of the connecting pipe 773 away from the sleeve 771, an upper piston 775 and a lower piston 776 arranged inside the oil cylinder 774, a lifting rod 777 arranged at the bottom of the lower piston 776, a matching air valve 778 arranged at the top of the oil cylinder 774, a control ring 779 arranged at the top of the assembly platform 1, and a notch 7710 opened at the top of the control ring 779.

[0066] When the cam 771 is in the closed position, the cam 772 is in the closed position, and the cam 773 is in the closed position, so that the cam 773 can be turned off.

[0067] By setting the regulating component 77, when loading, the signal antenna 9 passes through the placement hole 6 and is placed above the support plate 76. When adjusting the height, the support plate 76 can slide on the surface of the mounting frame 71 through the slide 74 to adaptively change the height. During this process, the push rod 772 slides in the sleeve 771, and the hydraulic oil in the sleeve 771 flows into the oil cylinder 774 through the connecting pipe 773. When the turntable 3 rotates the signal antenna 9 to enter the assembly area, the lifting rod 777 leaves the gap 7710 and is pushed upward by the control ring 779. The lower piston 776 moves upward to close the connecting pipe 773. In this way, the sleeve 771 is in a sealed state, and the push rod 772 can no longer move to support the slide 74 and the support plate 76, thereby lifting the signal antenna 9, so that it obtains sufficient supporting force and the state is more stable.

[0068] The remaining structures are the same as those of Example 1.

[0069] Example 3

[0070] Reference Figure 1 、 Figure 18-19 , which is the third embodiment of the present invention, is different from the first embodiment in that: a satellite antenna includes a signal antenna 9 placed in the placement hole 6, and also includes a sealing ring 10 arranged at the bottom edge of the signal antenna 9.

[0071] The signal antenna 9 is installed in the signal interface at the top of the satellite phone through threads. The bottom edge of the signal antenna 9 is chamfered, and the sealing ring 10 is wrapped around the outside of the chamfer and fixed with glue. The bottom surface of the sealing ring 10 protrudes from the bottom surface of the signal antenna 9.

[0072] By setting the sealing ring 10, when the signal antenna 9 is installed, the signal antenna 9 enters the signal interface. When the sealing ring 10 contacts the bottom wall of the signal interface, it is squeezed and deformed. The sealing ring 10 deforms and turns outward to fit the inner wall of the signal interface. In this way, a tightly sealed area is formed at the junction of the bottom wall and the inner wall of the signal interface. Water or dust in the harsh external environment cannot enter the signal connection between the signal interface and the signal antenna 9, avoiding poor contact and ensuring smooth signal.

[0073] Specifically, a shielding ring 11 is provided on the outside of the signal antenna 9. The cross-section of the shielding ring 11 is a right-angled triangle, and its right-angled side is in contact with the signal antenna 9 and fixed with glue. The bottom edge is in contact with the signal interface at the top of the satellite phone, which plays a shielding role and can further prevent water or dust from entering the signal interface.

[0074] The remaining structures are the same as those of Example 1.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
