Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of radar processing, and particularly relates to a radar cover gluing and pressing equipment. BACKGROUND

[0002] With the development of science and technology, the application of radar has gradually entered various fields of daily life. In order to protect the normal operation of radar in harsh environments, workers generally bond a radar cover on a vehicle-mounted radar, a weather radar and a navigation radar and other radars that need to adapt to different environments, so as to protect the main structure of the radar. In the bonding process of the radar cover and the radar, since the radar cover is produced by a molding process, a "surface layer" with weak physical and chemical properties will exist after demolding. The "surface layer" is mainly composed of demolding agent residues, low molecular weight resin components and an incomplete curing layer formed due to air inhibition. Therefore, the bonding is prone to be not firm. At this time, external pressure needs to be provided by a pressing equipment to press the two to enhance the bonding strength of the radar and the radar cover.

[0003] Although the existing radar cover bonding and pressing equipment can enhance the bonding effect of the two by applying a large amount of glue and pressing, the connection strength and the occlusion degree between the glue and the bonding surface of the radar cover are weak due to the existence of the weak "surface layer", which will cause the connection reliability between the radar and the radar cover to be insufficient, so that the finished product is difficult to adapt to harsh weather environments, greatly reducing the applicability and service life of the radar. If the bonding surface of the radar cover is pre-processed before bonding, the production efficiency of the radar will be affected by the processing process connection efficiency. In addition to pre-treating the bonding surface of the radar cover, workers also need to measure the radar cover one by one in advance and then treat the defects on the bonding surface in a targeted manner. This not only makes it difficult to guarantee the processing precision, but also further reduces the process connection, and the bonding rate of the radar cover and the radar is also affected. In view of this, the present application provides a radar cover gluing and pressing equipment. SUMMARY

[0021] S3, after the pressing process is completed and a new set of radomes is replaced, S1 is repeated.

[0022] The fixed seat 10 is provided with a polishing mechanism 40, the polishing mechanism 40 includes a limiting plate 41 fixedly arranged on the top surface of the fixed seat 10, an active block 42 slidably connected to the middle part of the limiting plate 41, the active block 42 is prevented from rotating with the rotating ring 12, a sandpaper 43 in frictional contact with the radome is arranged on the bottom surface of the active block 42, two extrusion rods 48 are arranged on the two sides of the active block 42, the middle part of the extrusion rod 48 is in a cylindrical structure, two latches 481 are symmetrically fixedly arranged at the two ends of the extrusion rod 48, a slot 425 is formed in the side wall of the active block 42 and matched with the latches 481, the latches 481 are in a U-shaped structure and radially provided with two protrusions, a groove is arranged in the slot 425 and matched with the protrusions, the extrusion rod 48 is fixed on the side wall of the active block 42 through the insertion of the two, a rod slot 426 is formed in the side wall of the active block 42 and matched with the extrusion rod 48, and the two extrusion rods 48 extrude and fix the sandpaper 43 at the two ends in the two rod slots 426, so as to fix the sandpaper 43, and the simple plug-in structure also facilitates the replacement of the sandpaper 43 by the staff after a long time of use.

[0023] The top surface of the rotating ring 12 is coaxially provided with a first ring groove 121, and a plurality of guide blocks 122 are fixedly arranged on the inner side wall of the first ring groove 121 in a ring-shaped equidistant structure. The arrangement of the guide blocks 122 makes the inner side wall of the first ring groove 121 form a wave-shaped structure. The bottom surface of the movable block 42 is fixedly provided with a guide rod 44 in sliding contact with the side wall of the guide block 122. When the guide rod 44 is pressed by the guide block 122, it translates away from the radar cover. The support spring 45 is fixedly arranged between the rear wall of the movable block 42 and the inner wall of the limiting plate 41. During the rotation of the rotating ring 12, the guide block 122 will press the guide rod 44 to move backward. Then, when the position of the guide rod 44 corresponds to the position between the adjacent two guide blocks 122, the rebound force of the support spring 45 will push the backward-moving movable block 42 forward, so that the movable block 42 moves back and forth as a whole. Through this movement path, the sandpaper 43 can perform the polishing operation on the radar cover. During the rotation in the first rotation direction, the sandpaper 43 can fully polish the bonding surface of the radar cover. In this way, not only can the weak "surface layer" generated by the mold pressing process on the radar cover be polished, but also a rough surface can be formed on the bonding surface, thereby increasing the bonding and engagement area between the glue and the radar cover, and further improving the bonding strength between the radar cover and the radar. The top surface of the rotating ring 12 is coaxially provided with a first ring groove 121, and a plurality of guide blocks 122 are fixedly arranged on the inner side wall of the first ring groove 121 in a ring-shaped equidistant structure. The arrangement of the guide blocks 122 makes the inner side wall of the first ring groove 121 form a wave-shaped structure. The bottom surface of the movable block 42 is fixedly provided with a guide rod 44 in sliding contact with the side wall of the guide block 122. When the guide rod 44 is pressed by the guide block 122, it translates away from the radar cover. The support spring 45 is fixedly arranged between the rear wall of the movable block 42 and the inner wall of the limiting plate 41. During the rotation of the rotating ring 12, the guide block 122 will press the guide rod 44 to move backward. Then, when the position of the guide rod 44 corresponds to the position between the adjacent two guide blocks 122, the rebound force of the support spring 45 will push the backward-moving movable block 42 forward, so that the movable block 42 moves back and forth as a whole. Through this movement path, the sandpaper 43 can perform the polishing operation on the radar cover. During the rotation in the first rotation direction, the sandpaper 43 can fully polish the bonding surface of the radar cover. In this way, not only can the weak "surface layer" generated by the mold pressing process on the radar cover be polished, but also a rough surface can be formed on the bonding surface, thereby increasing the bonding and engagement area between the glue and the radar cover, and further improving the bonding strength between the radar cover and the radar.

[0024] The movable block 42 is connected with the air bag 46 at the rear side, and the movable block 42 is provided with the air cavity 421 which is communicated with the inside of the air bag 46, and the air cavity 421 is provided with a plurality of air outlets 422 at the bottom surface, and the air bag 46 is fixedly provided with the fixed plate 47 at the end away from the movable block 42, and the fixed plate 47 is fixedly connected with the inner wall of the limiting plate 41, and the fixed plate 47 is slidingly connected with the movable block 42, and the air bag 46 is provided with the opening at both ends, and the fixed plate 47 is provided with the air inlet 471 which is communicated with the inside of the air bag 46, and the limiting plate 41 is provided with the notch at the position opposite to the air inlet 471, and the air cavity 421 is fixedly provided with the partition plate 423 at the lower part, and the air cavity 421 is divided into two parts by the partition plate 423, and the two parts are large and small, and the upper part is provided with the L-shaped structure and has a large space, and the lower part is provided with the linear structure and has a small space, and under the above design and the opening of the two spaces, the gas which is squeezed into the air cavity 421 by the air bag 46 is divided into two parts and injected into the upper and lower sides, respectively, and the opening end of the air cavity 421 is hingedly provided with the first baffle 424 on the upper and lower sides of the partition plate 423 through the torsion spring, and the first baffle 424 can only rotate towards the inside of the air cavity 421, and the air inlet 471 is hingedly provided with the second baffle 472 through the torsion spring, and the second baffle 472 can only rotate towards the air bag 46, and under the above structure, the first baffle 424 and the second baffle 472 can realize the one-way valve effect at the two opening ends of the air bag 46, respectively, so that the outside air can enter the air bag 46 from the air inlet 471 and be discharged from the air outlet 422, and the direction is irreversible, and the air bag 46 is contracted by the reaction force of the inner wall of the limiting plate 41 during the rear movement of the movable block 42, and because the internal space is reduced, the gas in the air bag 46 is discharged from the air outlet 422, and the discharged gas has a large flow and a fast flow rate for the position being polished, so that the dust generated during polishing can be blown away, and the adhesion effect is avoided due to the dust remaining on the adhesion surface, and during the subsequent forward movement of the movable block 42, because the air bag 46 is fixedly connected with the movable block 42 and the fixed plate 47 at the front and rear ends, respectively, the air bag 46 is pulled to the original position, and the air bag 46 can rapidly supplement a sufficient amount of air into the air bag 46 for next use due to the elasticity of the air bag 46.

[0025] The plurality of air outlets 422 are arranged in a T-shaped structure, the plurality of air outlets 422 above the sandpaper 43 are arranged in a straight line and arranged behind the partition plate 423, a small amount of air outlets 422 are arranged, so that the gas injected in the lower air cavity 421 can fully act on the sandpaper 43, and the straightly arranged air outlets 422 can blow the middle of the sandpaper 43 to vibrate, because the sandpaper 43 itself is soft and not easy to break, and its two ends are fixed by the pressing rod 48, and in addition, the lower air cavity 421 separated by the partition plate 423 and its opening end are extremely limited, so the gas will only cause a very narrow gap between the sandpaper 43 and the movable block 42, according to Bernoulli's principle, if the gap is narrow and the gas flow is fast, the pressure will decrease, and the air on the other side of the sandpaper 43 is relatively static, and the pressure is relatively high, so the pressure difference will generate a net pressure to push the paper to the low pressure area, and the sandpaper 43 itself has a certain flexibility and elasticity, when the gas flow continues to act, the restoring force of the sandpaper 43 will try to pull it back to its original position, and then the sandpaper 43 can be shaken to shake off the dust adhered to the sandpaper 43 due to the polishing operation, and compared with manual cleaning, such cleaning method is not only convenient and fast but also more thorough.

[0026] The plurality of air outlets 422 on the front side of the sandpaper 43 are arranged in a square array and arranged in front of the partition plate 423, and the plurality of air outlets 422 arranged in the front square array blow the air in the upper air cavity 421 on the radome, thereby blowing off the dust left on the radome to ensure the cleanliness of the bonding surface, thereby ensuring the firmness of the bonding is not affected by the dust. The lower part of the air outlet 422 is arranged in a rearward inclined structure, which allows the air outlet 422 on the front side to blow towards the bonding surface of the radome, and allows the gas of the air outlet 422 on the rear side to blow backward to avoid collision with the front airflow to cause dust residue.

[0027] The fixed seat 10 is provided with a pressing mechanism 20, the pressing mechanism 20 includes a fixed frame 21 fixedly arranged on the top surface of the fixed seat 10, a hydraulic rod 22 fixedly arranged on the bottom surface of the fixed frame 21, a three-jaw chuck 23 fixedly arranged on the lower end of the hydraulic rod 22, and a radar clamped in the three-jaw chuck 23. The operator can fix the radar or take out the radar and the radome together by controlling the opening and closing of the clamping jaw of the three-jaw chuck 23.

[0028] The fixed seat 10 is further provided with a gluing mechanism 50, the gluing mechanism 50 comprising a moving frame 51 slidingly connected to the top surface of the movable block 42, the lower end of the moving frame 51 being in T-shaped structure, and the top surface of the movable block 42 being provided with a groove in sliding cooperation with the lower end of the moving frame 51, the groove also being in T-shaped structure so as to allow the moving frame 51 to translate therein, and the moving frame 51 being fixedly provided with a compression spring 511 between the top surface of the movable block 42 and the clamping layer thereof, so as to ensure that the relative position of the moving frame 51 and the movable block 42 remains unchanged in the absence of external force, and the moving frame 51 being fixedly provided with a sleeve 52 at the front side thereof, and the upper portion of the moving frame 51 being in L-shaped structure, and the two ends thereof being fixed to the rear end and the middle portion of the sleeve 52 through two annular structures respectively, so as to ensure the stability of the sleeve 52 when moving together with the moving frame 51.

[0029] The top surface of the limiting plate 41 is fixedly provided with a glue bucket 54, the top surface of the glue bucket 54 being provided with a internally-threaded pipe 541 therethrough, and the internally-threaded pipe 541 being threadedly connected with a threaded cover 542, and the glue bucket 54 can be filled with glue by unscrewing the threaded cover 542.

[0030] The lower end of the sleeve 52 is in T-shaped cylindrical structure, and the lower opening end of the sleeve 52 is slidingly provided with a discharge pipe 53, the top surface of the discharge pipe 53 being in closed structure, and the upper portion of the discharge pipe 53 being symmetrically provided with two discharge ports 531, the discharge ports 531 being normally blocked by the inner wall of the lower side of the sleeve 52, and the two sides of the discharge pipe 53 being symmetrically fixedly provided with two slide rods 532, the slide rods 532 being slidingly connected to the bottom surface of the sleeve 52, and the top surface of the slide rods 532 being fixedly provided with a return spring 533 between the clamping layer and the inner wall of the sleeve 52, and under the absence of external force, the discharge pipe 53 always remains at the position of the lower end of the sleeve 52 under the dual action of the return spring 533 and gravity, and the discharge ports 531 thereon also remain in the state of being blocked by the inner wall of the sleeve 52, and although the glue will be poured into the inside of the sleeve 52 under the influence of gravity and the principle of communicating vessels, the discharge pipe 53 is blocked, and the glue will stay in the inside of the sleeve 52, and the rear of the sleeve 52 is connected with a corrugated pipe 521, the rear end of the corrugated pipe 521 extending into the inside of the glue bucket 54 through the front wall thereof, and the middle portion of the corrugated pipe 521 being provided in downwardly-bent U-shaped structure.

[0031] In the second rotation direction, the guide rod 44 drives the movable block 42 outward, at this time the bottom surface of the movable block 42 is completely separated from the contact with the radome, and the polishing work is completed, and the gluing mechanism 50 on the movable block 42 is also moved outward synchronously. Since the lower end of the discharge pipe 53 is V-shaped structure, and the inclined surface position can be extruded in contact with the radome, therefore, the inclined side wall of the discharge pipe 53 will rise along the inside of the sleeve pipe 52 after being extruded by the inner wall of the radome, then the discharge port 531 on it will be communicated with the inside of the sleeve pipe 52, and the glue in the sleeve pipe 52 will enter the discharge pipe 53 from the discharge port 531 and finally leave from the lower end of the discharge pipe 53. During the sliding contact between the guide rod 44 and the second ring groove 123, the lower end of the discharge pipe 53 also has a ring-shaped sliding contact with the bonding surface of the radome. Therefore, not only the gluing operation can be completed, but also the effect similar to the dispensing process can be achieved, which can improve the precision of the glue application, ensure that the narrow ring-shaped structure of the bonding surface of the radome can be fully coated with glue, and ensure the bonding effect and sealing quality. Furthermore, such gluing process can also reduce the consumption of glue and reduce waste.

[0032] The upper part of the sleeve pipe 52 is inclined, when the radome is rotated one circle under the drive of the supporting plate 11 and the rotating ring 12, the gluing operation of the gluing mechanism 50 on the bonding surface is completed, then the staff can drive the radome to be pressed down by the pressing mechanism 20, the edge position of the radome will extrude the inclined part of the sleeve pipe 52 from above, so that the sleeve pipe 52 moves backward with the moving frame 51, then the lower end of the discharge pipe 53 will pass over the bonding surface of the radome, under the action of gravity and the rebound force of the return spring 533, the discharge pipe 53 moves downward and the discharge port 531 on it is blocked by the inner wall of the sleeve pipe 52 again, so the glue stops leaving outward, and the removed sleeve pipe 52 cannot block the bonding between the radome and the radar, the staff only needs to press the two for a sufficient time by the pressing mechanism 20 to ensure that the bonding surfaces of the two are fully bonded under the action of the glue, so that the processing of the radome and the radar is completed.

[0033] It should be noted that the speed of the servo motor 32 driving the supporting plate 11 and the rotating ring 12 to rotate in the device is uniform and relatively slow, which leaves enough operation time for the polishing operation of the polishing mechanism 40 and the gluing operation of the gluing mechanism 50. At the same time, the number of circles in the first rotation direction needs to ensure that the number of sliding contact circles between the guide rod 44 and the first ring groove 121 is an integer, and there are enough circles for polishing operation, and the number of circles in the second rotation direction needs to ensure that the number of sliding contact circles between the guide rod 44 and the second ring groove 123 is at least one integer, which ensures that the gluing operation can completely cover the ring-shaped bonding surface of the radome.

[0034] Working principle: the staff can fix radar and radome respectively on the three-jaw chuck 23 and the supporting plate 11 of the device, then drive the supporting plate 11 and the rotating ring 12 to rotate through the servo motor 32, in the first rotation direction, the polishing mechanism 40 will polish the bonding surface of the radome, so as to eliminate the weak "surface layer" produced by the mold pressing process, and to improve the contact area between the bonding surface and the glue, then drive the supporting plate 11 to rotate along the second rotation direction through the servo motor 32, so as to coat the bonding surface of the radome, after the coating is completed, then use the pressing mechanism 20 to press the two to bond the two through the auxiliary glue, finally only need to use the pressing mechanism 20 to take out the finished product from the supporting plate 11 again, the staff operates the three-jaw chuck 23 to loosen the radar and takes out the finished product.

[0035] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
