Description

Technical Field

[0001] The present invention relates to the field of laser detection technology, and in particular to a device and method for detecting the flatness of an antenna reflection arc surface. Background Art

[0002] The antenna reflection surface refers to the conductive curved surface or plane in the planar antenna that is used to concentrate and reflect the electromagnetic waves emitted by the feed source in a certain direction according to certain requirements to enhance the transmission effect. When used for reception, it can enhance the received signal strength and improve the reception effect. It is referred to as the reflection surface.

[0003] The reflective arc surface of a large antenna is composed of flat plates, and a large reflective arc surface is built by the flat plates for reflection.

[0004] In order to ensure the performance of the reflective arc surface, it is usually necessary to test the flatness of each plane plate to prevent the plane flatness from not meeting the standard and affecting the accuracy of the final antenna reflective arc surface and the effect of subsequent concentrated reflection.

[0005] Currently, laser detection equipment is used to perform high-precision flatness detection. For example, patent announcement No. CN221325418U discloses a profile flatness detection device, which includes an operating table. By starting the reduction motor to drive the rotating shaft and the gear to rotate clockwise or counterclockwise, the rack engaged with the gear drives the movable plate and the connecting block to move left and right, so that the profile on the detection plate can be detected from left to right. The control adjustment motor drives the threaded rod to rotate clockwise or counterclockwise. At this time, the nut plate drives the laser detector to move forward and backward, so that the profile on the detection plate can be detected from front to back.

[0006] See also Fig. 9 As shown, the laser detection device emits a laser fan that is aligned with the plane to be measured. The laser fan intersects with the plane to be measured to form a scanning line. When the laser detection device moves along the y-axis direction, the scanning surface is obtained by scanning the scanning line. That is to say, in the above scheme, surface scanning is performed along the y-axis direction, and line scanning is performed along the x-axis direction, which greatly reduces the scanning efficiency in the x-axis direction.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Based on the background technology, it is known that more comprehensive detection can be achieved by moving the laser detection device in different directions relative to the plane to be detected. However, the problem is that when facing multi-directional detection, the scanning surface cannot be maintained at the maximum width.

[0022] See also Figures 1 to 11As shown, the first embodiment provides a device for detecting the flatness of the arc-shaped surface of an antenna reflection, in order to be able to scan the surface of the board to be tested (i.e. Fig.11 The plane to be measured in the figure) is provided here including a base 1 and a laser detection mechanism, the top surface of the base 1 is provided with a guide component 2 for inserting and guiding the plate to be measured, and one side of the top surface of the base 1 is provided with an extrusion component 3; The laser detection mechanism includes a distance control component 4 and a detection component 5. The distance control component 4 is arranged on the side of the top surface of the base 1 away from the extrusion component 3. The detection component 5 is arranged on the driving end of the distance control component 4, and the detection component 5 is facing the plate to be tested on the insertion guide component 2. The detection assembly 5 includes a placement frame 51, a detection substrate 6, a horizontal driving member 52 and a vertical driving member 53. The placement frame 51 includes a basic frame 511 and a placement stand 512. The basic frame 511 is a square frame. The placement stand 512 is slidably arranged on a side frame of the basic frame 511 close to the guide assembly 2. The detection substrate 6 is slidably arranged on the placement stand 512. The horizontal driving member 52 is arranged on one side of the basic frame 511. The horizontal driving member 52 can drive the placement stand 512 to move horizontally, and the moving direction of the placement stand 512 is parallel to the detection surface of the plate to be tested. The vertical driving member 53 is arranged above the placement stand 512. The output end of the vertical driving member 53 acts on the detection substrate 6, so that the detection substrate 6 slides along the placement stand 512. The placement stand 512 and the detection substrate 6 on the placement stand 512 can be controlled by the horizontal driving member 52 to move horizontally, so as to perform flatness detection on the plate to be tested in the horizontal direction through the detection substrate 6. The detection base 6 includes a spin control ring sleeve 61 and a laser detection component 62. A vertical guide groove is opened on the mounting frame 512. The spin control ring sleeve 61 is slidably set in the guide groove of the mounting frame 512. The laser detection component 62 is set on the inner side of the spin control ring sleeve 61, so that the laser detection component 62 can spin in the spin control ring sleeve 61, thereby controlling the relative angle between the laser detection component 62 and the board to be tested. After the laser detection component 62 rotates, the detection base 6 can be driven by the vertical driving component 53 to slide vertically along the mounting frame 512. At this time, the flatness of the board to be tested can be detected in the vertical direction through the detection base 6.

[0023] In addition, since the spin control ring 61 can control the laser detection component 62 to rotate to any angle, through the cooperation of the horizontal drive component 52 and the vertical drive component 53, the laser detection component 62 rotated to any angle can move the laser scanning line on the surface of the board to be tested in a direction perpendicular to the laser scanning line, thereby forming a scanning surface with the largest area, which can more comprehensively scan the surface of the board to be tested. At the same time, this multi-directional regional scanning can avoid the influence of striped undulations and sunken areas on the surface of the board to be tested on the scanning, and more accurate flatness data can be obtained through overlapping scanning of multiple areas.

[0024] The spin control ring sleeve 61 includes a lifting ring seat 611, an inner rotating sleeve 612 and a control motor 613. The lifting ring seat 611 is arranged in contact with the inner wall of the guide groove of the mounting stand 512. The inner rotating sleeve 612 is rotatably arranged on the inner side of the lifting ring seat 611. The laser detection component 62 is arranged on the inner side of the inner rotating sleeve 612. The control motor 613 is arranged on the lifting ring seat 611, and the output end of the control motor 613 acts on the inner rotating sleeve 612. The control motor 613 is a stepping motor capable of controlling the rotation angle, so that the output end of the control motor 613 can be rotated by a certain angle to control the inner rotating sleeve 612 and the laser detection component 62 to rotate by the same angle.

[0025] The lifting ring seat 611 includes a ring seat and a placement seat, wherein the placement seat fits the inner wall of the guide groove of the placement stand 512, and the ring seat is arranged above the placement seat, the inner rotating sleeve 612 is arranged inside the ring seat, the control motor 613 is arranged between the placement seat and the ring seat, and an extrusion rotary pad is arranged at the output end of the control motor 613, a through groove is opened on the side wall of the ring seat, and the edge of the extrusion rotary pad passes through the through groove and squeezes the inner rotating sleeve 612, and the extrusion rotary pad is tightly connected with the inner rotating sleeve 612, so that the control motor 613 can drive the extrusion rotary pad to rotate and squeeze the inner rotating sleeve 612 to rotate inside the ring seat part of the lifting ring seat 611, thereby driving the laser detection component 62 to spin; Furthermore, a vertical long groove is provided on the inner wall opposite to the guide groove of the placement stand 512, and a protrusion that fits the vertical long groove is provided at the edge of the placement seat portion of the lifting ring seat 611.

[0026] The guide assembly 2 includes a mounting frame 21 and a guide track 22. The mounting frame 21 is arranged on one side of the top surface of the base 1. The mounting frame 21 includes an upper and lower plate body. The guide track 22 includes two mirrored tracks, which are respectively arranged on the opposite side walls of the upper and lower plates of the mounting frame 21. A vertical guide channel is formed between the two guide tracks 22, and the guide channel is perpendicular to the detection end of the laser detection component 62. The guide track 22 is a track that is wide on both sides and narrow in the middle. Fig. 9As shown, the board to be tested can be inserted vertically along the wider side of the guide track 22 and fit into the narrow channel portion in the middle of the guide track 22 .

[0027] The laser detection component 62 includes a light source component 621 and an alignment plate 622. The light source component 621 is arranged on the inner side of the spin control ring sleeve 61, and the laser emitting end of the light source component 621 is facing the vertical guide channel. The alignment plate 622 is arranged at the edge of the emitting end of the light source component 621, and the alignment plate 622 is parallel to the laser line emitted from the laser output end of the light source component 621. Before the laser is emitted through the light source component 621, the position of the emitted laser line can be determined by the alignment plate 622.

[0028] like Fig. 9 , Fig.10 and Fig.11 As shown, the light source assembly 621 can form laser lines at multiple angles on the surface of the board to be tested through the action of the spin control ring 61, and then through the cooperation of the horizontal driving member 52 and the vertical driving member 53, the laser scanning line can be moved in a direction perpendicular to the laser scanning line, so that the light source assembly 621 can keep the scanning surface at the maximum width when detecting flatness at multiple angles, thereby forming a scanning surface with the largest area on the board to be tested.

[0029] The extrusion assembly 3 includes a driving cylinder 31 and an extrusion top ring 32. The driving cylinder 31 is arranged on a side of the placement frame 21 away from the placement frame 51. The extrusion top ring 32 is arranged at the output end of the driving cylinder 31, and the extrusion top ring 32 is perpendicular to the guide channel between the two guide rails 22. When the plate to be tested is inserted into the guide channel between the two guide rails 22, the driving cylinder 31 can drive the extrusion top ring 32 to move forward and squeeze the plate to be tested to fit into the guide rail 22, thereby locking the position of the plate to be tested in the guide rail 22.

[0030] The distance control assembly 4 includes a control push rod 41 and an extrusion pad frame 42. The control push rod 41 is horizontally arranged on the side of the top surface of the base 1 away from the extrusion assembly 3. The base frame 511 is arranged at the end of the control push rod 41. The extrusion pad frame 42 is arranged on the side of the base frame 511 close to the guide track 22. Among them, the basic frame 511 is a square frame, and four extrusion pad frames 42 are set in a group at the four corners of the end of the basic frame 511, and the four extrusion pad frames 42 are perpendicular to the guide channel between the two guide rails 22. The length of the extrusion pad frames 42 at the end of the basic frame 511 is adjustable. When the board to be tested is inserted into the guide channel and the extrusion on one side is completed by the extrusion assembly 3, the control push rod 41 controls the basic frame 511 to move forward, and the four extrusion pad frames 42 will contact the other side of the board to be tested from four points, thereby forming an opposite extrusion of the board to be tested, and can also make the end of the basic frame 511 close to the board to be tested by a certain distance, so as to facilitate the detection base 6 on the basic frame 511 to detect the board to be tested, and the distance can be changed by adjusting the length of the extrusion pad frames 42.

[0031] It should be clear that the extrusion assembly 3 and the extrusion pad 42 form opposite extrusion on both sides of the plate to be tested, which can help stabilize the entire plate to be tested in the guide track 22 and prevent the plate to be tested from being affected by the work of other workpieces during the detection process, causing slight displacement and vibration, thereby ensuring the accuracy of laser flatness detection.

[0032] Working principle: first, insert the plate to be tested vertically into the guide channel between the two guide rails 22, and guide the plate to be tested to fit the narrow channel part in the middle of the guide rail 22 through the guidance of the guide rail 22, and then start the driving cylinder 31 to drive the extrusion top ring 32 to move forward and squeeze the plate to be tested to fit in the guide rail 22, thereby locking the position of the plate to be tested in the guide rail 22. At this time, the control push rod 41 can be started to control the base frame 511 to move forward, so that the four extrusion pads 42 at the end of the base frame 511 are against the other side of the plate to be tested at four points, thereby determining the position between the base frame 511 and the plate to be tested. At this time, the detection base 6 part on the basic frame 511 is facing the board to be tested, the light source assembly 621 is started, and the laser line emitted by the light source assembly 621 is facing the board to be tested, and then the horizontal driving member 52 is started to control the mounting stand 512 and the horizontal movement of the detection base 6 on the mounting stand 512, so that the laser line of the light source assembly 621 sweeps across the surface of the entire board to be tested, completing the surface scanning and flatness detection in the horizontal direction of the surface of the board to be tested, and starting the control motor 613 to drive the inner rotating sleeve 612 to rotate on the inner side of the ring seat part of the lifting ring seat 611, thereby driving the light source assembly 621 and the alignment horizontal plate 622 to rotate to the horizontal. When the detection base 6 is vertically moved along the mounting frame 512, the vertical driving member 53 can be started to drive the detection base 6 to slide vertically along the mounting frame 512. At this time, the laser line of the light source assembly 621 can be vertically scanned across the surface of the plate to be tested and the flatness detection can be completed. In addition, the inner rotating sleeve 612 can be driven to rotate and tilt on the inner side of the ring seat part of the lifting ring seat 611 by controlling the motor 613, so that the light source assembly 621 and the alignment horizontal plate 622 can be rotated to the tilted angle, and then the horizontal driving member 52 and the vertical driving member 53 can be started at the same time to drive the light source assembly 621 to slide vertically along the mounting frame 512 while driving the mounting frame 512 to move horizontally, so that the light source assembly 621 can be shaped The moving path is inclined. At this time, the laser line of the light source assembly 621 will be obliquely scanned on the surface of the board to be tested to complete the flatness detection in the inclined direction. It can complete multi-directional and multi-angle flatness detection in the horizontal, vertical and inclined directions to reduce errors. After the board to be tested completes the flatness detection, the driving cylinder 31 is started to drive the extrusion top ring 32 to reset, and the board to be tested is no longer squeezed to fit in the guide track 22. The control push rod 41 is then started to drive the basic frame 511 to reset, and the extrusion pad 42 leaves the surface of the board to be tested. At this time, the board to be tested can be pushed to move forward along the guide channel between the two guide tracks 22, so as to remove the board to be tested.

[0033] A detection method using the above-mentioned antenna reflection arc surface flatness detection device is performed, and the method steps are as follows: S1, first insert the plate to be tested vertically into the guide channel between the two guide rails 22, and let the plate to be tested fit the narrow channel part in the middle of the guide rails 22 through the guidance of the guide rails 22, and then start the driving cylinder 31 to drive the extrusion top ring 32 to move forward and squeeze the plate to be tested to fit in the guide rails 22, thereby locking the position of the plate to be tested in the guide rails 22; S2, start the control push rod 41, control the basic frame 511 to move forward, so that the four extrusion pads 42 at the end of the basic frame 511 contact the other side of the board to be tested at four points, determine the position between the basic frame 511 and the board to be tested, and at this time, the detection base 6 on the basic frame 511 is facing the board to be tested; S3, start the light source assembly 621, let the laser line emitted by the light source assembly 621 face the board to be tested, then start the horizontal driving member 52 to control the placement stand 512 and the detection base 6 on the placement stand 512 to move horizontally, let the laser line of the light source assembly 621 sweep the surface of the entire board to be tested, complete the surface scanning of the board to be tested in the horizontal direction, and complete the flatness detection in the horizontal direction; S4, the laser detection member 62 can be driven to spin by the spin control ring 61, so that the angle between the laser line of the light source assembly 621 and the surface of the board to be tested changes to horizontal, and then the vertical drive member 53 can be started to drive the detection base 6 to slide vertically along the mounting stand 512, and then the laser line of the light source assembly 621 can be vertically scanned across the surface of the board to be tested, completing the surface scanning of the board to be tested in the vertical direction, and completing the flatness detection in the vertical direction; S5, the spin control ring 61 can be started again to drive the laser detection member 62 to spin, so that the relative angle between the laser line of the light source assembly 621 and the surface of the board to be tested is tilted. At this time, the horizontal driving member 52 and the vertical driving member 53 are started at the same time to drive the detection base 6 to slide vertically along the mounting stand 512 while driving the mounting stand 512 to move horizontally, so that the detection base 6 forms an inclined moving path. At this time, the laser line of the light source assembly 621 will sweep obliquely across the surface of the board to be tested, completing the flatness detection in the inclined direction; S6. After the flatness test of the plate to be tested is completed, the driving cylinder 31 is started to drive the extrusion top ring 32 to reset, and the plate to be tested is no longer pressed to fit in the guide track 22. Then the control push rod 41 is started to drive the basic frame 511 to reset, and the extrusion pad 42 leaves the surface of the plate to be tested. At this time, the plate to be tested can be pushed forward along the guide channel between the two guide tracks 22, so as to remove the plate to be tested.
