Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of assembly and auxiliary equipment, in particular to a quasi-optical feeder network device assembly detection platform. BACKGROUND

[0002] The quasi-optical assembly system can be divided into three modules of quasi-optical assembly, electrical performance scanning and product turnover. The quasi-optical assembly module is mainly composed of a position adjusting mechanism and a posture adjusting mechanism. Its function is mainly to realize the position and posture adjustment of quasi-optical devices in the quasi-optical feeder network assembly process. At the same time, the end of the posture adjusting mechanism is guaranteed to adjust the position and posture of the quasi-optical device with the adjusting mechanism through the clamping mechanism. The electrical test scanning module is a scanning frame for electrical performance test of quasi-optical network. Its functions include plane scanning function and polarization conversion function. The product turnover module realizes the turnover of the quasi-optical network assembly state, and achieves the purpose of quasi-optical network assembly on both sides.

[0003] At present, due to the matching under the three-coordinate detection gantry, it is difficult to manually operate the feeding and discharging due to the space and high load restrictions. During the quasi-optical network assembly, each part is installed on the front and back surfaces of the bottom plate according to the fixed position. During the assembly, the back surface can be assembled only by turning over the bottom plate. Due to the limitation of three-coordinate measurement range, the size of the quasi-optical assembly system needs to be controlled within the three-coordinate measurement range, which results in insufficient space inside the quasi-optical assembly system to arrange the turnover mechanism. In addition, when multiple products need to be detected at the same time, the tedious operation of feeding and discharging multiple times reduces the detection efficiency and cannot realize the automatic completion of multiple product detection simultaneously. Therefore, a product turnover module is needed to realize the turnover of the quasi-optical network during the assembly process, and the turnover module can cooperate with the assembly detection mechanism inside the three-coordinate.

Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more, unless otherwise explicitly limited.

[0042] The present invention will be further described in detail below with reference to specific embodiments:

[0043] 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:

[0044] An assembly and testing platform for quasi-optical feed network devices includes a fixing mechanism 1 and a flipping mechanism 2.

[0045] 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.

[0046] The turnover frame 23 comprises two first fixed plates 231 arranged symmetrically, and each of the first fixed plates 231 is provided with two groups of first roller groups 232 arranged in parallel on the side close to each other. The first fixed plates 231 are provided with first positioning assemblies 233 at both ends in the conveying direction of the first roller groups 232. The two first roller groups 232 form a first gap 232a therebetween, and the two sides of the jig 4 are connected in the first gap 232a.

[0047] In the embodiment, the turnover driving device 22 can be a motor, which comprises a driving end 221 and a supporting end 222. The supporting end 222 can be a bearing and a rotating shaft, and the driving end 221 and the bearing end are connected at the center of the side of the two first fixed plates 231 away from each other. The distance between the first gap 232a is greater than the thickness of the edge of the jig 4. The first gap 232a is adjusted to be horizontal, and the jig 4 is driven by manual or other transfer equipment to enter the first gap 232a, and the two sides of the jig 4 are overlapped on the first roller groups 232 and moved along the first roller groups 232 to be completely inside the first gap 232a.

[0048] The two ends of the first fixed plate 231 are provided with the first positioning assembly 233. The first positioning assembly 233 comprises a second fixed plate 2331 fixedly connected with the first fixed plate 231, a third fixed plate 2332 connected with the second fixed plate 2331 through a first guide rail 2333, and symmetrically arranged positioning portions 2334 arranged at the upper end and the lower end of the third fixed plate 2332. The two positioning portions 2334 are arranged directly above and below the first gap 232a, respectively. The second fixed plate 2331 and the third fixed plate 2332 are further connected through a first lead screw 2335. When the first lead screw 2335 rotates, the third fixed plate 2332 can be driven to move along the first guide rail 2333. The two 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.

[0049] In the embodiment, after the jig 4 enters the first gap 232a, the first lead screw 2335 is rotated through the handle 2336, the positioning portion 2334 is driven to move downward by the second fixed plate 2331, so that the upper positioning portion 2334 presses downward on the jig 4, and then the jig 4 is pressed tightly with the lower first roller group 232, so as to realize the positioning of the jig 4. After the turnover, the lower handle 2336 is turned upward. At this time, the handle 2336 is rotated again, so that the positioning portion 2334 moves downward, so that the lower positioning portion 2334 drives the jig 4 to move downward to contact the first roller group 232. Then, the lower positioning portion 2334 is separated from the jig 4, and the jig 4 can be pushed to move along the first gap 232a on the first roller group 232 to the second track.

[0050] In order to avoid the situation that the jig 4 slides in the first gap 232a and leaves the first gap 232a when the jig 4 is turned to about 90 degrees during the turning process, a stopper 2311 is arranged at each end of the first fixed plate 231, and the stoppers 2311 on the two first fixed plates 231 extend and protrude from the first gap 232a on the side close to each other. When the jig 4 tends to slide in the first gap 232a and leave the first gap 232a, the first stopper 2311 blocks it. After the turning is completed, the first stopper 2311 is manually removed so that the jig 4 can enter the second track. Of course, in other embodiments, the stopper 2311 can be driven by a pneumatic cylinder or a motor to move close to or away from the first gap 232a to block the jig 4.

[0051] A first stop lever 2312 is arranged on the first fixed plate 231, the length direction of the first stop lever 2312 is perpendicular to the length direction of the first gap 232a, and the middle of the first stop lever 2312 is connected to the first fixed plate 231; the ends of the two first stop levers 2312 arranged symmetrically on the two first fixed plates 231 are connected by a second stop lever 2313. In this embodiment, after the quasi-optical power feeding device is installed on the jig 4, the overall structure is relatively complex, and the height is much greater than the thickness of the jig 4 itself. Therefore, through the arrangement of the first stop lever 2312 and the second stop lever 2313, a protection function is formed, so that the jig 4 after installing the quasi-optical power feeding network device can avoid being interfered by other unexpected situations during the turning.

[0052] The turning mechanism 2 further comprises a first limiting assembly 24, which comprises a first driving device 241 arranged on the second rack 21, and a limiting groove 242 arranged on the side away from each other of the two first fixed plates 231; 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 insert into the limiting groove 242.

[0053] In this embodiment, when the turning frame 23 is in a horizontal state, the first limiting rod 243 is inserted into the limiting groove 242 to ensure that the jig 4 can stably enter and exit the first gap 232a; when the turning frame 23 is turned, the first driving device 241 drives the first limiting rod 243 to reset to avoid interference with the turning.

[0054] The fixing mechanism 1 comprises a first rack 11, a lifting device 12, and two parallel first tracks 13 connected by the lifting device 12, and the first rack 11 further comprises two parallel second tracks 14 connected with the first tracks 13.

[0055] The plane where the upper end surface of the second track 14 is located is on the same plane as the plane where the middle of the first gap 232a is located.

[0057] The first rack 11 is provided with a second limiting assembly 16, the second limiting assembly 16 comprises a second limiting rod 161 arranged vertically, and a limiting plate 162 arranged in the movement direction of the first track 13 and away from one end of the second track 14; the second limiting rod 161 is connected with the limiting hole 41 on the jig 4; the jig 4 moves along the first track 13 to abut against the limiting plate 162.

[0058] In the embodiment, the first rack 11 is a marble platform, and is placed on the three-coordinate platform 3. The two baffles 111 play a guiding and limiting role, and the distance between the two baffles 111 should be equal to the distance between the two first fixed plates 231. And the side of the two baffles 111 close to the turnover mechanism 2 is provided with a slope, and the two baffles 111 together form an outwardly expanding opening, so as to facilitate the transmission of the jig 4 in the turnover mechanism 2 to the second track 14. When the jig 4 moves to the first track 13, and the end of the jig 4 abuts against the limiting plate 162, the lifting device 12 drives the first track 13 to move downward, and then drives the jig 4 to move downward, to the jig 4 moves to the lower end and is overlapped on the lower marble platform, and the first track 13 is separated from the jig 4. In the process of downward movement of the jig 4, the second limiting rod 161 is inserted into the limiting hole 41 on the jig 4; at the same time, when the jig 4 descends, the second driving device 151 drives the pressing plate 152 to press downward the jig 4, so that the jig 4 is fixed on the marble platform.

[0059] In the embodiment, the operation process of the quasi-optical feeder network device detection platform is as follows:
