Description

Technical Field

[0001] This invention relates to the field of laser detection device technology, specifically to a laser detection fixture for security monitoring cameras. Background Technology

[0002] Laser-based camera inspection is a core process that relies on non-contact, high-precision beam technology to perform full-dimensional performance verification of cameras. It uses a laser beam with micron-level precision as the detection carrier and, through the principle of beam illumination and reflection imaging, accurately captures details such as solder joint size, component spacing, and installation position deviation inside the camera module. It will not cause mechanical damage to fragile components such as CMOS sensors and lens assemblies, and can also penetrate into compact internal spaces that traditional tools cannot reach, completing the investigation of hidden defects that are difficult to cover by traditional inspection methods.

[0003] In existing technologies, in order to perform circular detection of cameras, the cameras need to be stopped during the transportation process, and then the cameras are rotated using a rotating device so that the cameras rotate one full circle at the detection point of the laser detector. During the rotation, the position of the cameras at the detection point of the laser detector needs to be controlled to avoid deviations in the laser refraction angle, which would affect the accuracy of the laser detector in detecting the surveillance cameras. Therefore, a new type of laser detection fixture for security surveillance cameras is needed. Summary of the Invention

The end of the first elastic element away from the telescopic rod is installed inside the telescopic cylinder. A connecting block is installed on one of the opposite sides of the two telescopic rods. A connecting plate is installed on the upper surface of the connecting block. The bearing is installed on the upper surface of the connecting plate. The detection element is installed on the side of the connecting block.

[0009] Furthermore, the conveying component includes multiple arc-shaped plates, which are mounted on the upper surface of the connecting block. The gears and bearings are all arranged within the space formed by the multiple arc-shaped plates. Conveying plates are mounted on the sides of the arc-shaped plates, and the two ends of the two conveying plates are in sliding contact with the input conveyor belt and the output conveyor belt, respectively.

[0010] Furthermore, the detection component includes a detection rod, which is installed on the side of the connecting block. A detection block is installed on the side of the detection rod away from the connecting block. The detection block is slidably connected in a groove. A detection plate is installed on the upper surface of the detection block facing outward from the mounting frame. A laser detector is installed on the side of the detection plate facing inward from the mounting frame.

[0011] Furthermore, the material-taking component includes a vertical rod, and vertical rods are installed on both sides of the upper surface of the reciprocating plate. A material-taking rod is installed at the end of the vertical rod away from the reciprocating plate. A deflection groove is opened at the end of the material-taking rod away from the vertical rod.

[0013] Furthermore, an intercepting cylinder is installed in the mounting frame on the side near the input conveyor belt, and an intercepting block is slidably connected inside the intercepting cylinder. A second elastic element is installed on the side of the intercepting block facing the inside of the intercepting cylinder, and the end of the second elastic element away from the intercepting block is installed inside the intercepting cylinder.

[0014] Furthermore, an interceptor plate is installed inside the mounting frame on the side near the output conveyor belt, and the interceptor plate makes intermittent contact with the connecting block.

[0015] This invention provides a laser detection fixture for security surveillance cameras, which has the following advantages: 1. This invention involves installing a rack on one side of the mounting frame, and then installing a rotating structure consisting of gears, a rotating rod, and bearings on the upper surface of a reciprocating plate. The reciprocating plate moves to drive the rotating structure to contact the rack, thereby achieving rotation of the rotating structure. A detection structure consisting of a detection rod, a detection block, a detection plate, and a laser detector is then installed on the side of the connecting block. By controlling the distance between the detection structure and the rotating structure, the laser refraction angle is ensured to remain within acceptable limits. Finally, a ring-shaped detection is performed on the monitoring camera placed on the rotating structure, increasing the accuracy of the laser detector in detecting the monitoring camera.

[0016] 2. This invention uses a material-grabbing structure consisting of a vertical rod, a material-grabbing rod, and a material-grabbing plate installed on the upper surface of a reciprocating plate. The material-grabbing structure simultaneously pulls up two monitoring cameras. Then, a reciprocating structure consisting of a reciprocating threaded rod, a reciprocating threaded block, and a reciprocating plate drives a rotating structure and a detection structure to move back and forth, thereby detecting the two monitoring cameras and improving detection efficiency.

[0017] 3. This invention involves installing a conveying structure consisting of an arc-shaped plate and a conveying plate on the annular surface of a rotating structure. Then, an intercepting structure consisting of an intercepting cylinder, an intercepting block, and a second elastic element, as well as an intercepting plate, are installed on both sides of the mounting frame. When the reciprocating structure drives the rotating structure to move from the input conveyor belt to the output conveyor belt, the connecting block contacts the intercepting plate when the rotating structure reaches it. At this point, the rotating structure stops moving, while the reciprocating structure continues to drive the two monitoring cameras to move via the material-picking structure until the monitoring camera on the gear moves to the conveying plate near the output conveyor belt. At this point, the monitoring camera near the input conveyor belt moves onto the gear. Subsequently, when the reciprocating structure drives the rotating structure to move towards the intercepting structure near the input conveyor belt, the intercepting structure intercepts the monitoring camera near the input conveyor belt and pushes it onto the conveying plate near the output conveyor belt, thus achieving automatic unloading of the two pulled-out monitoring cameras.

[0020] Please see Figures 1 to 7 The present invention provides a technical solution: a laser detection fixture for security monitoring cameras, including an input conveyor belt 1 and an output conveyor belt 2, with a mounting frame 33 disposed between the input conveyor belt 1 and the output conveyor belt 2. A servo motor 7 is installed at the bottom of the mounting frame 33, and a reciprocating threaded rod 19 is installed at the output end of the servo motor 7. A reciprocating threaded block 17 is threadedly connected to the annular surface of the reciprocating threaded rod 19, and a reciprocating plate 18 is installed on the upper surface of the reciprocating threaded block 17. When the servo motor 7 is started, it drives the reciprocating threaded rod 19 to rotate, and the rotation of the reciprocating threaded rod 19 drives the reciprocating threaded block 17 and the reciprocating plate 18 to move back and forth within the mounting frame 33.

[0021] Mounting plates 21 are installed on both sides of the upper surface of the reciprocating plate 18. Telescopic cylinders 22 are installed on opposite sides of the two mounting plates 21. Telescopic rods 28 are inserted into the telescopic cylinders 22. A first elastic element 32, which is a spring, is installed at one end of the telescopic rod 28 inside the telescopic cylinder 22. In its normal state, the end of the first elastic element 32 away from the telescopic rod 28 is installed inside the telescopic cylinder 22. A connecting block 31 is installed on opposite sides of the two telescopic rods 28. A connecting plate 24 is installed on the upper surface of the connecting block 31. The device is equipped with a bearing 30, and a rotating rod 29 is installed inside the bearing 30. A gear 5 is installed at the end of the rotating rod 29 away from the bearing 30. A rack 6 is installed on one side inside the mounting bracket 33. The gear 5 meshes with the rack 6. A limiting groove 8 is opened on the upper surface of the gear 5. The limiting groove 8 is used to limit the surveillance camera. An arc plate 16 is installed on the upper surface of the connecting plate 24. The gear 5 and the bearing 30 are both set on the inner annular surface of the arc plate 16. A conveyor plate 4 is installed on the side of the arc plate 16. The two conveyor plates 4 slide in contact with the input conveyor belt 1 and the output conveyor belt 2, respectively.

[0022] A rack 6 is installed on one side of the mounting bracket 33, and a rotating structure consisting of a gear 5, a rotating rod 29, and a bearing 30 is installed on the upper surface of the reciprocating plate 18. The rotating structure is driven to contact the rack 6 by the movement of the reciprocating plate 18, thereby realizing the rotation of the rotating structure. A detection structure consisting of a detection rod 23, a detection block 9, a detection plate 10, and a laser detector 14 is installed on the side of the connecting block 31. By controlling the distance between the detection structure and the rotating structure, it is ensured that the laser refraction angle will not deviate. Then, a ring detection is performed on the monitoring camera placed on the rotating structure to increase the detection accuracy of the monitoring camera by the laser detector 14.

[0023] A detection rod 23 is installed on the side of the connecting block 31. A detection block 9 is installed on the side of the detection rod 23 away from the connecting plate 24. A sliding groove 13 is provided on the side of the mounting bracket 33 away from the rack 6. The detection block 9 is slidably connected in the sliding groove 13. A detection plate 10 is installed on the upper surface of the side of the detection block 9 facing the outside of the mounting bracket 33. A laser detector 14 is installed on the side of the detection plate 10 facing the inside of the mounting bracket 33. The laser detector 14 is used to detect the size of the gap at the installation location of the surveillance camera housing. When the connecting block 31 moves in the mounting bracket 33, the connecting block 31 drives the detection rod 23 to move, and the detection rod 23 drives the detection block 9 to move in the sliding groove.

[0024] Vertical rods 25 are installed on both sides of the upper surface of the reciprocating plate 18. A material-taking rod 11 is installed at the end of the vertical rod 25 away from the reciprocating plate 18. A deflection groove is opened at the end of the material-taking rod 11 away from the vertical rod 25. A material-taking plate 20 is set in the deflection groove. The material-taking plate 20 extends above the input conveyor belt 1. A deflection rod 27 is installed in the deflection groove. A circular hole is opened on the lower side of the material-taking plate 20. The deflection rod 27 is rotatably connected in the circular hole. A torsion spring 26 is installed on the annular surface of one end of the deflection rod 27 in the circular hole. The end of the torsion spring 26 away from the deflection rod 27 is installed in the circular hole. The rotation of the threaded rod 19 drives the reciprocating threaded block 17 and the reciprocating plate 18 to move towards the input conveyor belt. When the conveyor belt 1 moves to one side, the pick-up plate 20 contacts the monitoring camera on the input conveyor belt 1 and is deflected into the deflection groove by the monitoring camera. At the same time, the torsion spring 26 is in a tightened state. When the pick-up plate 20 separates from the monitoring camera, the torsion spring releases the torsion force and rotates the pick-up plate 20 out of the deflection groove again. When the threaded rod 19 rotates and drives the reciprocating threaded block 17 and the reciprocating plate 18 to move to the output conveyor belt 2 side, when the pick-up plate 20 contacts the monitoring camera, the monitoring camera squeezes the pick-up plate 20 again. However, at this time, the pick-up plate 20 contacts the edge of the deflection groove. At this time, the monitoring camera can be pulled onto the conveyor plate 4 and the gear 5.

[0025] By installing a material-grabbing structure consisting of a vertical rod 25, a material-grabbing rod 11, and a material-grabbing plate 20 on the upper surface of the reciprocating plate 18, two monitoring cameras can be pulled up simultaneously using the material-grabbing structure. Then, the reciprocating structure consisting of a reciprocating threaded rod 19, a reciprocating threaded block 17, and a reciprocating plate 18 drives the rotating structure and the detection structure to move back and forth, thereby detecting the two monitoring cameras and improving detection efficiency.

[0026] An intercepting cylinder 3 is installed inside the mounting frame 33 on the side near the input conveyor belt 1. An intercepting block 12 is slidably connected inside the intercepting cylinder 3. A second elastic element, which is a spring, is installed on the side of the intercepting block 12 facing inside the intercepting cylinder 3. The second elastic element is in a normal state. The end of the second elastic element away from the intercepting block 12 is installed inside the intercepting cylinder 3. An intercepting plate 15 is installed inside the mounting frame 33 on the side near the output conveyor belt 2. The intercepting plate 15 is in intermittent contact with the connecting block 31.

[0027] By installing a conveying structure consisting of an arc plate 16 and a conveying plate 4 on the annular surface of the rotating structure, and then installing an intercepting structure consisting of an intercepting cylinder 3, an intercepting block 12, and a second elastic element, as well as an intercepting plate 15 on both sides of the mounting frame 33, when the reciprocating structure drives the rotating structure to move from the input conveyor belt 1 to the output conveyor belt 2, the connecting block 31 contacts the intercepting plate 15 when the rotating structure reaches the intercepting plate 15. At this time, the rotating structure stops moving, while the reciprocating structure continues to drive the two monitoring cameras to move through the material picking structure until the monitoring camera on the gear 5 moves to the conveying plate 4 near the output conveyor belt 2. At this time, the monitoring camera on the side near the input conveyor belt 1 moves to the gear 5. Subsequently, when the reciprocating structure drives the rotating structure to move to the intercepting structure on the side near the input conveyor belt 1, the intercepting structure intercepts the monitoring camera on the side near the input conveyor belt 1 and pushes the monitoring camera on the side near the input conveyor belt 1 to the conveying plate 4 near the output conveyor belt 2, thereby realizing automatic unloading of the two monitoring cameras.

[0028] In summary, when using this laser detection fixture for security monitoring cameras, the servo motor 7 is first started to drive the reciprocating threaded rod 19 to rotate. The rotation of the reciprocating threaded rod 19 drives the reciprocating threaded block 17 and the reciprocating plate 18 to move towards the input conveyor belt 1. While the reciprocating plate 18 moves towards the input conveyor belt 1, it drives the material-taking structure composed of the vertical rod 25, the material-taking rod 11, and the material-taking plate 20 to extend above the input conveyor belt 1, so that the material-taking plate 20 contacts the monitoring camera to be detected. After the material-taking plate 20 contacts the monitoring camera to be detected, it is held by the monitoring camera to be detected and deflected into the deflection groove until the two monitoring cameras to be detected move between the two material-taking structures. At this time, the reciprocating threaded block 17 moves to the position furthest from the servo motor 7. At this time, the monitoring camera to be detected near the output conveyor belt 2 is squeezed into the limiting groove 8 opened on the gear 5.

[0029] After the reciprocating threaded block 17 moves to the position furthest from the servo motor 7, it moves back to the output conveyor belt 2. During the movement of the reciprocating plate 18, it drives the gear 5 to contact the rack 6, causing the gear 5 to rotate while moving. The rotation of the gear 5 drives the monitoring camera to be tested, which is placed in the limiting groove 8 and is close to the output conveyor belt 2, to rotate. At this time, the laser detector 14 detects the size of the gap at the installation location of the monitoring camera housing.

[0030] When gear 5 rotates one revolution, it means that the gap of the monitoring camera has been completely detected by laser detector 14. At this time, the connecting block 31 near the output conveyor belt 2 is in contact with the intercepting plate 15. Since the reciprocating screw block 17 has not yet moved to the side closest to the output conveyor belt 2, the reciprocating screw block 17 and the reciprocating plate 18 continue to drive the material picking structure to move towards the output conveyor belt 2. Meanwhile, gear 5 is blocked by the intercepting plate 15 and cannot move. At the same time, the first elastic element 32 in the intercepting cylinder 3 near the output conveyor belt 2 is in a compressed state, and the first elastic element 32 in the intercepting cylinder 3 away from the output conveyor belt 2 is in a stretched state until the reciprocating screw block 17 and the reciprocating plate 18 move to the position closest to the output conveyor belt 2. At this time, the material picking structure uses the monitoring camera to be detected near the input conveyor belt 1 to squeeze the monitoring camera to be detected near the output conveyor belt 2 out of gear 5, so that the monitoring camera to be detected near the output conveyor belt 2 moves to the conveying plate 4 near the output conveyor belt 2.

[0031] At this time, the servo motor 7 rotates again, driving the reciprocating threaded block 17 and the reciprocating plate 18 to move closer to the input conveyor belt 1. At this time, the gear 5 moves and re-engages with the rack 6 and rotates in the opposite direction. At this time, the laser detector 14 detects the size of the gap at the installation location of the monitoring camera housing until the gear 5 rotates one revolution again and moves to the interception structure composed of the interception cylinder 3, the interception block 12, and the second elastic element. At this time, as the reciprocating threaded block 17 and the reciprocating plate 18 continue to drive the gear 5 to move closer to the input conveyor belt 1, the monitoring camera on the gear 5 is intercepted by the interception structure and pushed to the conveyor plate 4 closer to the output conveyor belt 2. The multiple monitoring cameras on the conveyor plate 4 closer to the output conveyor belt 2 are then squeezed and fall onto the output conveyor belt 2 in sequence. At this time, the material picking structure pulls two cameras to be tested from the input conveyor belt 1 again.

[0032] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
