Description

Technical Field

[0001] The invention belongs to the technical field of thin film antennas, and relates to a modular manufacturing device and a modular manufacturing method for a thin film reflective surface antenna thread film structure. Background Art

[0002] The thin film reflector antenna is a type of high-precision reflector antenna, and its main structure is divided into three parts: basic support structure, cable net structure and reflector surface. The cable net structure is further divided into front cable net, rear cable net and vertical cable, in which multiple triangular structures are formed on the front net surface, and the reflector surface is divided into multiple triangular membranes laid on the front cable net surface to form a cable membrane overall structure.

[0003] The cable-membrane structure under the traditional concept needs to be produced separately. First, each cable segment is cut according to the designed cable segment length and the tension inside the cable, and then manually woven into the entire cable net. Finally, triangular membrane sheets of designed size are cut out and pasted on the basic cable net structure in sequence to complete the overall production of the cable-membrane structure.

[0004] The current manufacturing method has many shortcomings. First, the cable membrane structure is an integral structure, and adjacent triangular membranes share a cable. When replacing one of the cable segments or triangular membranes, all surrounding structures need to be disassembled, which seriously fails to meet the interchangeability requirements; second, there are many cable segments in the cable net structure, which need to be manually woven into a net according to the topological relationship of the cable net, and the process is messy and cumbersome; third, the film shape needs to be cut into the designed triangle in advance, and then pasted on the cable net structure in turn. Since the pasting of the electrode membrane is carried out after the antenna basic cable net structure is built, and the laying and pasting are carried out in a suspended state, it is difficult to ensure that the adjacent sides of the adjacent triangular membranes are pasted evenly, and the surface after pasting is difficult to ensure flatness, and it is also difficult to match the shape of the cable net. The above defects cause the manufactured antenna prototype to deviate from the design result, which in turn brings inconvenience to the prototype experiment. Therefore, it is necessary to propose a manufacturing scheme for the thin film reflector antenna to solve the above problems without switching the workbench. Summary of the invention

[0005] In order to solve the above-mentioned defects existing in the prior art, the purpose of the present invention is to provide a modular manufacturing device for a thin film reflective antenna filament structure, which solves the problems of lack of interchangeability, complicated manufacturing process, and poor manufacturing effect in the prior art.

[0087] One end of the triangular cable net unit 5 is clamped at the first rope end clip 203-4 at the end of the cantilever assembly 203, and a rope loop is formed near the third positioning pin 206, and a pressure ring 701 is put on, and the rope loop is put on the third positioning pin 206; the rope is wound around the first positioning pin 204, and a rope loop is formed near the first positioning pin 204, and a pressure ring 701 is put on, and the rope loop is put on the first positioning pin; the rope is wound around the second positioning pin 205, and then a rope loop is formed near the second positioning pin 205, and a pressure ring 701 is put on, and the rope loop is put on the second positioning pin;

[0088] After passing around the second positioning pin 205, the rope continues to go back to the third positioning pin 206, and the other end of the rope passes through the pressure ring 701, passes around the third positioning pin 206 and the fixed pulley 203-5 in sequence, and is clamped on the second rope end clip 303 of the cable net tension adjustment device 3; at this point, the ropes wound between the three positioning pins form a triangular cable net unit 5;

[0089] Step 4: The cable net tension adjustment device 3 tensions and pulls the triangular cable net unit 5 under the control of the power source, determines that each cable segment reaches the set tension according to the force sensor, and positions and locks the rope on the rope ring of the cable net positioning pin through the rope clamping device:

[0090] The tension in the third rope segment 503 is calculated according to the data of the first force sensor 401-1 at the first positioning pin 204. When the tension value reaches the set tension T3 of the third rope segment, the traction is stopped. Then the pad 702 is placed under the pressure ring 701. The punch 703 and the punch hammer 704 are used to press the pressure ring onto the rope ring to complete the determination of the tension in the third rope segment 503.

[0091] The cable net tension adjustment device 3 relaxes the traction and re-traction of the triangular cable net unit 5, calculates the tension in the cable segment 1 501 according to the data of the second force sensor 402-1 at the second positioning pin 205, stops the traction when the tension value reaches the set tension T1 of the cable segment 1, places the pad under the pressure ring, and uses the punch and the punch hammer to press the pressure ring onto the rope ring, thereby completing the determination of the tension in the cable segment 1 501;

[0092] The cable net tension adjustment device 3 relaxes the traction again, and re-tows the triangular cable net unit, calculates the tension in the second cable segment 502 according to the data of the second force sensor 402-1 at the second positioning pin 205, stops traction when the tension value reaches the set tension T2 of the second cable segment, places the pad under the pressure ring, and uses the punch and the punch hammer to press the pressure ring onto the rope ring to complete the determination of the tension in the second cable segment 502; thus, the cable force adjustment of the three cable segments of the triangular cable net unit is completed;

[0093] Step 5: Cut off the excess rope ends at both ends of the rope, keep the triangular cable net in a taut state, and complete the production of the triangular cable net unit;

[0094] Step 6: manufacturing a modular triangular cable-membrane structure unit 10;

[0095] Cut a rectangular film 8, the length of the rectangle is greater than the length of the base of the triangle, the width is equal to the height of the triangle, the reverse side of the film faces upward, and it is laid flatly under the triangular cable net unit 5;

[0096] Use a special adhesive tape 9 to respectively stick the three tensioned cable segments and the film together, and after sticking, cut off the excess film along the edge of the tape to complete the sticking of the triangular film, and obtain a modular triangular cable-membrane structural unit 10;

[0097] The linear motion component 201 and the planar motion component 202 respectively retreat a short distance toward the first positioning pin 204 to relax the triangular cable net unit 5, remove the triangular cable net with the film attached, and complete the manufacture of the triangular cable-membrane structure unit 10.

[0098] When in use, the triangular cable-membrane structural unit in a relaxed state needs to be tensioned and hung to the corresponding position. For example, in a thin film reflector antenna, several triangular cable-membrane structural units can be tensioned into an integral cable-membrane structure after being hung together. Each triangular cable-membrane structural unit in a tensioned state retains the cable segment length and cable segment internal force at the time of manufacture.

[0099] The invention effectively solves the problems of complicated electrode surface manufacturing, poor interchangeability, large error, etc. of the existing thin film reflector antenna. The triangular cable membrane structure unit can be obtained by the method of the invention.
