Description

Technical Field

[0001] This invention relates to the field of assembly and auxiliary equipment technology, and in particular to an assembly and testing platform for quasi-optical feed network devices. Background Technology

[0002] The quasi-optical assembly system can be divided into three modules: quasi-optical adjustment, electrical performance scanning, and product flipping. The quasi-optical adjustment module mainly consists of a position adjustment mechanism and an attitude adjustment mechanism. Its function is primarily to adjust the position and attitude of the quasi-optical components during the assembly of the quasi-optical feed network. Simultaneously, the attitude adjustment mechanism's end uses a clamping mechanism to ensure the quasi-optical components adjust their position and attitude along with the adjustment mechanism. The electrical testing scanning module serves as the scanning frame for testing the electrical performance of the quasi-optical network, and its functions include planar scanning and polarization conversion. The product flipping module enables the flipping of the quasi-optical network assembly state, achieving the purpose of assembling the quasi-optical network on both sides.

[0003] Currently, due to space and high load limitations when integrated with a coordinate measuring machine (CMM) gantry, manual loading and unloading are difficult. During the assembly of the quasi-optical network, each component is installed in a fixed position on both sides of the base plate. The base plate needs to be flipped to the back for assembly. Due to the limitations of the CMM's measurement range, the overall dimensions of the quasi-optical assembly system must be controlled within this range, resulting in insufficient internal space for a flipping mechanism. Furthermore, the cumbersome loading and unloading operations required when multiple products need simultaneous inspection lead to low inspection efficiency and prevent simultaneous automated multi-product inspection. Therefore, a product flipping module is needed to enable the quasi-optical network to flip during assembly, and this flipping module should be able to cooperate with the assembly and inspection mechanisms within the CMM. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly and testing platform for quasi-optical feed network devices, so as to solve the problems of flipping quasi-optical feed network devices and docking with the testing platform in the prior art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0022] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-6 As shown, this invention is applied to the assembly and testing of quasi-optical feed network devices, specifically to its assembly and testing platform. Because the assembly system of quasi-optical feed network devices is mounted under a coordinate measuring machine (CMM) gantry, space and high load limitations make manual loading and unloading difficult. Under normal operation, only single-product multi-faceted testing can be achieved through multiple transfers, and after single-face testing, a flipping operation is required. Furthermore, when multiple products need to be tested simultaneously, the cumbersome loading and unloading operations are repeated, resulting in low testing efficiency and making it impossible to achieve simultaneous automatic multi-product testing. Therefore, this invention designs a fixed mechanism under the CMM gantry and a flipping mechanism outside the CMM and connected to the fixed mechanism. The fixture is loaded from the flipping mechanism to the fixed mechanism, completing the assembly and testing of one face; then it returns to the flipping mechanism for flipping, and after flipping, it enters the fixed mechanism for the assembly and testing of the other face. Specifically: An assembly and testing platform for quasi-optical feed network devices includes a fixing mechanism 1 and a flipping mechanism 2.

[0023] The flipping mechanism 2 includes a second frame 21, a flipping drive device 22 mounted on the second frame 21, and a flipping frame 23 connected to the flipping drive device 22. The flipping drive device 22 drives the flipping frame 23 to rotate.

[0024] The tilting frame 23 includes two symmetrically arranged first fixing plates 231. Two sets of parallel first roller groups 232 are provided on adjacent sides of each first fixing plate 231. First positioning components 233 are provided at both ends of the first fixing plates 231 in the conveying direction of the first roller groups 232. A first gap 232a is formed between the two first roller groups 232, and both sides of the fixture 4 are connected within the first gap 232a.

[0025] In this embodiment, the flipping drive device 22 can be a motor, including a drive end 221 and a support end 222. The support end 222 can be a bearing and a rotating shaft. The drive end 221 and the bearing end are respectively connected to the center of the two first fixed plates 231 on opposite sides. The spacing of the first gap 232a is greater than the thickness of the edge of the fixture 4. The first gap 232a is adjusted to be horizontal. The fixture 4 is driven by a person or other transfer equipment to enter through the first gap 232a. Its two sides overlap the first roller group 232 and move along the first roller group 232 until it is completely inside the first gap 232a.

[0026] Both ends of the first fixed plate 231 are provided with first positioning components 233. The first positioning components 233 include a second fixed plate 2331 fixedly connected to the first fixed plate 231, and a third fixed plate 2332 connected to the second fixed plate 2331 via a first guide rail 2333. The upper and lower ends of the third fixed plate 2332 are respectively provided with symmetrical positioning parts 2334, which are respectively located directly above and below the first gap 232a. The second fixed plate 2331 and the third fixed plate 2332 are also connected by a first lead screw 2335. When the first lead screw 2335 rotates, it can drive the third fixed plate 2332 to move along the first guide rail 2333. Both ends of the first lead screw 2335 protrude from the first fixed plate 231 and the second fixed plate 2331, and are provided with handles 2336.

[0027] In this embodiment, after the fixture 4 enters the first gap 232a, the first lead screw 2335 is rotated by the handle 2336, which drives the positioning part 2334 to move downward through the second fixing plate 2331. This causes the upper positioning part 2334 to press down on the fixture 4, thereby pressing the fixture 4 against the lower first roller group 232, thus positioning the fixture 4. After flipping, the lower handle 2336 is flipped upward. At this time, rotating the handle 2336 again causes the positioning part 2334 to move downward, causing the lower positioning part 2334 to drive the fixture 4 downward until the fixture 4 contacts the first roller group 232. After that, the lower positioning part 2334 disengages from the fixture 4, allowing the fixture 4 to move along the first gap 232a on the first roller group 232 to the second track.

[0028] To prevent the jig 4 from sliding and disengaging from the first gap 232a during the flipping process, when the jig 4 is flipped to approximately 90 degrees, stop blocks 2311 are provided at both ends of the first fixing plate 231. The stop blocks 2311 on the two first fixing plates 231 extend towards each other and protrude from the first gap 232a. When the jig 4 tends to slide and disengage from the first gap 232a, it is blocked by the first stop blocks 2311. After the flipping is completed, the first stop blocks 2311 are manually removed so that the jig 4 can enter the second track. Alternatively, in other embodiments, the stop blocks 2311 can be driven by a cylinder or motor to move closer to or further away from the first gap 232a to achieve the function of blocking the jig 4.

[0029] A first stop bar 2312 is provided on the first fixed plate 231. The length direction of the first stop bar 2312 is perpendicular to the length direction of the first gap 232a, and the center of the first stop bar 2312 is connected to the first fixed plate 231. The ends of the two first stop bars 2312 symmetrically arranged on the two first fixed plates 231 are connected by a second stop bar 2313. In this embodiment, after the quasi-optical feeding device is installed on the fixture 4, the overall structure is relatively complex, and the height is much greater than the thickness of the fixture 4 itself. Therefore, the first stop bar 2312 and the second stop bar 2313 provide protection, preventing the fixture 4 after the quasi-optical feeding network device is installed from being interfered with by other unexpected situations when it is flipped.

[0030] The flipping mechanism 2 also includes a first limiting component 24, which includes a first driving device 241 mounted on the second frame 21 and a limiting groove 242 mounted on one side of the two first fixing plates 231 that are far apart from each other. A first limiting rod 243 is connected to the first driving device 241, and the first driving device 241 can drive the first limiting rod 243 to be inserted into the limiting groove 242.

[0031] In this embodiment, when the flipping frame 23 is in a horizontal state, the first limiting rod 243 is inserted into the limiting groove 242 to ensure that the fixture 4 can stably enter and exit the first gap 232a; when the flipping frame 23 flips, the first driving device 241 drives the first limiting rod 243 to reset to avoid interference with its flipping.

[0032] The fixing mechanism 1 includes a first frame 11, a lifting device 12, and two parallel first tracks 13 connected by the lifting device 12. The first frame 11 is also provided with two parallel second tracks 14 connected to the first tracks 13.

[0033] The plane containing the upper end face of the second track 14 is on the same plane as the plane containing the center of the first gap 232a.

[0034] The first frame 11 is provided with two symmetrical baffles 111, which are respectively located on both sides of the two second tracks 14. The baffles 111 are provided with pressing devices 15, which include a second driving device 151 connected to the baffles 111 and a pressure plate 152 connected to the second driving device 151. The second driving device 151 can drive the pressure plate 152 to press the fixture 4 downward.

[0035] The first frame 11 is provided with a second limiting component 16, which includes a vertically arranged second limiting rod 161 and a limiting plate 162 disposed in the direction of movement of the first track 13 and away from the end of the second track 14; the second limiting rod 161 is engaged with the limiting hole 41 on the fixture 4; the fixture 4 moves along the first track 13 until it abuts against the limiting plate 162.

[0036] In this embodiment, the first frame 11 is a marble platform and is placed on the coordinate measuring machine platform 3. Two baffles 111 serve as guides and limiters, and the distance between the two baffles 111 should be equal to the distance between the two first fixing plates 231. Both baffles 111 have inclined surfaces on the side near the flipping mechanism 2, forming an outwardly expanding opening to facilitate the transfer of the fixture 4 within the flipping mechanism 2 to the second track 14. When the fixture 4 moves to the first track 13 and its end abuts against the limiting plate 162, the lifting device 12 drives the first track 13 downward, thereby driving the fixture 4 downward until its lower end rests on the marble plate below, and the first track 13 disengages from the fixture 4. During the downward movement of the fixture 4, the second limiting rod 161 inserts into the limiting hole 41 on the fixture 4; simultaneously, as the fixture 4 descends, the second driving device 151 drives the pressure plate 152 downward to press against the fixture 4, thus fixing the fixture 4 to the marble plate.

[0037] In this embodiment, the operation process of the quasi-optical feed network device testing platform is as follows: First, the flipping frame 23 is in a horizontal state, that is, the first gap 232a is in a horizontal state, and the first limiting rod 243 is inserted into the limiting groove 242. The fixture 4 is manually or transported by equipment into the flipping mechanism 2 through the first gap 232a until the fixture 4 is completely inside the first gap 232a. The fixture 4 is pushed further and enters the second track 14 between the two baffles 111, and slides along the second track 14 to the first track 13. The fixture 4 stops when the end of the fixture 4 touches the limiting plate 162. The lifting component drives the first track 13 to move downward, and then the fixture 4 moves downward. The limiting hole 41 on the fixture 4 is connected to the second limiting rod 161. The fixture 4 moves downward until the marble contacts the marble plate and stops. The first track 13 continues to move downward a certain distance and disengages from the fixture 4. The second driving device 151 drives the pressure plate 152 to move downward and press against the fixture 4, so that the fixture 4 is stably fixed on the marble platform for the assembly and testing of the device on one side of the fixture 4. The marble platform is also equipped with an assembly device 17 for a multi-degree-of-freedom robotic arm and a testing device 18.

[0038] After assembly and testing, the pressing device 15 is reset, the lifting component is reset, the first track 13 moves upward to be on the same plane as the second track 14, the fixture 4 on the first track 13 is manually pushed to the second track 14, and continues to be pushed into the first gap 232a; when the fixture 4 is completely inside the first part, the positioning part 2334 moves downward by rotating the handle 2336, pressing the fixture 4 to the first roller group 232 below the fixture 4, and installing the stop block 2311; the first limiting rod 243 is reset and disengaged from the limiting groove 242; the flipping drive device 22 drives the fixture 4 to rotate 180 degrees through the flipping frame 23, so that the unassembled side of the fixture 4 faces upward; the first limiting rod 243 is inserted into the limiting groove 242, and the stop block 2311 is removed; the fixture 4 is pushed into the first track 13 by manual or other equipment through the second track 14; the above actions are repeated. After the other side of fixture 4 is assembled and inspected, it is conveyed out through the second track 14 and the first gap 232a in sequence, and fixture 4 is replaced to carry out the assembly and inspection of the next fixture 4.
