Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, specifically a high-precision visual inspection device. Background Technology

[0002] Currently, in order to ensure that radar quality meets factory requirements during the production process, visual inspection equipment is generally used to inspect it. This inspection equipment mainly uses a CCD camera as an image acquisition device to convert the target to be inspected into image signals. Then, a dedicated image processing system processes and analyzes these signals to achieve intelligent recognition of the object's appearance, size, and defects. Only after passing the inspection can the radar meet the various indicators required for leaving the factory.

[0003] For example, the patent document with authorization announcement number CN213843054U proposes a high-precision nano-visual inspection device. Although this utility model solves the problems that the light source and camera can only move in one direction and the inspected product can only be fixed, it avoids the deviation of the inspected product during the inspection process, thereby making the inspection results more accurate and improving the operability and practicality of the device.

[0004] However, during use, it was found that after the object to be tested was placed on the loading platform, the bottom of the object could not be aligned with the camera vertically, resulting in blind spots in the shooting and making the detection process less comprehensive, thus reducing the accuracy of the detection.

[0005] Therefore, it is necessary to provide a new high-precision visual inspection device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a high-precision visual inspection device that can flip the object being tested to ensure a comprehensive inspection process.

[0007] To solve the above-mentioned technical problems, the high-precision visual inspection equipment provided by this utility model includes: a body and an outer shell fixedly installed on the top of the body. A camera is provided inside the outer shell, and an aperture is provided below the camera. A first steering shaft is rotatably installed on one side of the outer shell. A support frame is fixedly installed at one end of the first steering shaft inside the outer shell. A double-ended screw is rotatably installed inside the support frame. Two linkage plates are threaded on the double-ended screw. A second steering shaft is rotatably installed on the side of the two linkage plates that are close to each other. A steering arm is fixedly installed on each of the two second steering shafts. A placement disc is fixedly installed on each of the two steering arms.

[0008] Preferably, anti-slip bushings are fixedly installed on the side of the two placement discs that are close to each other, and the inner diameter of one anti-slip bushing is larger than the outer diameter of the other anti-slip bushing.

[0009] Preferably, a drive shaft is rotatably mounted on the side of each of the two linkage plates that are close to each other, and a first spur gear is fixedly sleeved on each of the two drive shafts. A second spur gear is fixedly sleeved on each of the two steering shafts. The first spur gear meshes with the second spur gear respectively. A first servo motor is fixedly mounted on the top of the support frame. The output shaft of the first servo motor is fixedly connected to the top end of the double-ended screw. A second servo motor is fixedly mounted on the side of each of the two linkage plates that are far from each other. The output shafts of the second servo motor are fixedly connected to the far ends of the two drive shafts respectively.

[0010] Preferably, a curved through groove is provided on the steering shaft, and a rodless cylinder is fixedly installed on one side of the outer casing. A sliding rod is fixedly installed on the slider of the rodless cylinder, and the sliding rod passes through the curved through groove and contacts the inner wall of the curved through groove.

[0011] Preferably, a side plate is fixedly installed on the top inner wall of the outer casing. Two mounting protrusions are fixedly installed on the side plate. The same lifting screw is rotatably installed on the two mounting protrusions. A lifting arm is threaded onto the lifting screw. A connecting block is fixedly installed at the bottom of the lifting arm. The bottom of the connecting block is fixedly connected to the camera. Four folding rods are fixedly installed on the connecting block. The bottom ends of the four folding rods are all fixedly connected to the aperture.

[0012] Preferably, a scale bar is fixedly installed on the top inner wall of the outer casing. The scale bar passes through the lifting arm and is slidably connected to it. A set screw is threaded onto the lifting arm, and the end of the set screw abuts against the scale bar.

[0013] Preferably, two guide rods are fixedly installed inside the support frame, and the two guide rods pass through the two linkage plates and are slidably connected to the two linkage plates.

[0014] Compared with related technologies, the high-precision visual inspection equipment provided by this utility model has the following beneficial effects: This invention utilizes a steering shaft to rotate the support frame, thereby exchanging the orientation of the two placement discs. This allows the object being tested within the placement discs to be flipped, ensuring visual inspection of the object's bottom as well, improving the comprehensiveness of the inspection and thus enhancing the accuracy of the results. Furthermore, the combination of the curved through-groove and the sliding bar ensures that the rotation of the support frame alternates between forward and reverse rotation, preventing entanglement of external wiring and guaranteeing that the rotation angle of the support frame remains consistent.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the high-precision visual inspection equipment provided by this utility model; Figure 2 This is a schematic diagram of the internal structure of the outer shell in this utility model; Figure 3 This is a schematic diagram of the support frame in this utility model; Figure 4This is a schematic diagram of the connection structure between the lifting screw and the lifting arm in this utility model. The high-precision visual inspection equipment includes: a body 1 and an outer shell 2 fixedly installed on the top of the body 1. A camera 4 is installed inside the outer shell 2, and an aperture 5 is located below the camera 4. A steering shaft 6 is rotatably installed on one side of the outer shell 2. A support frame 7 is fixedly installed at one end of the steering shaft 6 inside the outer shell 2, and a double-ended screw 8 is rotatably installed inside the support frame 7. A servo motor 8 is fixedly installed on the top of the support frame 7, and its output shaft is fixedly connected to the top end of the double-ended screw 8. In addition, two linkage plates 9 are threadedly installed on the double-ended screw 8. In order to ensure that the linkage plates 9 form a stable linear lifting motion, two guide rods are fixedly installed inside the support frame 7. The two guide rods pass through the two linkage plates. The moving plate 9 is slidably connected to two linkage plates 9. A steering shaft 10 is rotatably mounted on the side of the two linkage plates 9 that is close to each other. A steering arm 11 is fixedly mounted on each of the two steering shafts 10. A placement disc 12 is fixedly mounted on each of the two steering arms 11. The placement disc 12 can support the object to be measured. Furthermore, an anti-slip bushing 13 is fixedly mounted on the side of the two placement discs 12 that is close to each other. The inner diameter of one anti-slip bushing 13 is larger than the outer diameter of the other anti-slip bushing 13. This can prevent the object from sliding off the placement disc 12. At the same time, one anti-slip bushing 13 can be inserted into the other anti-slip bushing 13, thereby preventing the two from colliding.

[0019] In the above method, in order to drive the placement disc 12 to rotate so that the upper placement disc 12 can rotate out from above the lower placement disc 12 without obstructing normal visual detection, a drive shaft 14 is rotatably installed on the side of the two linkage plates 9 that are close to each other. A first spur gear 15 is fixedly sleeved on each of the two drive shafts 14, and a second spur gear 16 is fixedly sleeved on each of the two steering shafts 10. The first spur gear 15 meshes with the second spur gear 16 respectively. A second servo motor is fixedly installed on the side of the two linkage plates 9 that are far apart from each other. The output shafts of the two second servo motors are fixedly connected to the ends of the two drive shafts 14 that are far apart from each other.

[0020] In this method, in order to drive the support frame 7 to rotate forward and backward, and at the same time ensure that each rotation is 180°, a curved through groove 17 is provided on the steering shaft 6. A rodless cylinder 18 is fixedly installed on one side of the outer shell 2, and a sliding rod 19 is fixedly installed on its built-in slider. The sliding rod 19 passes through the curved through groove 17 and contacts the inner wall of the curved through groove 17. In the initial state, the sliding rod 19 contacts the side wall of the curved through groove 17 in the horizontal direction. When the sliding rod 19 moves from one side wall to another side wall, it means that the support frame 7 has rotated 180°.

[0021] In this method, to provide the camera 4 with a height adjustment function, a side plate is fixedly installed on the top inner wall of the housing 2. Two mounting protrusions 20 are fixedly installed on the side plate, and the same lifting screw 21 is rotatably installed on the two mounting protrusions 20. A lifting arm 22 is threaded onto the lifting screw 21. A connecting block 3 is fixedly installed at the bottom of the lifting arm 22. The bottom of the connecting block 3 is fixedly connected to the camera 4. Four folding rods are fixedly installed on the connecting block 3. The bottom ends of the four folding rods are fixedly connected to the aperture 5. Furthermore, a scale rod 23 is fixedly installed on the top inner wall of the housing 2. The scale rod 23 passes through the lifting arm 22 and is slidably connected to it. In this way, the height position of the camera 4 can be adjusted by rotating the lifting screw 21. In order to ensure that the lifting arm 22 remains fixed after being adjusted to the specified height, a set screw is threaded onto the lifting arm 22. The end of the set screw abuts against the scale rod 23.

[0022] The working principle of the high-precision visual inspection equipment provided by this utility model is as follows: During the detection process, the object to be tested is first placed on the lower placement disk 12. Then, the upper servo motor 2 is started in the forward direction. Its output shaft drives the corresponding drive shaft 14 to rotate. Through the meshing of the corresponding sprocket 15 and sprocket 2 16, the upper steering shaft 2 10 can be rotated, thereby rotating the upper placement disk 12. When the placement disk 12 rotates out from above the lower placement disk 12, the lower placement disk 12 is no longer blocked by other objects and is directly below the camera 4. Then, the aperture 5 and the camera 4 can be used for detection. After the top of the object being tested is inspected, in order to inspect its bottom, the upper servo motor 2 is first started in reverse to rotate the upper placement disk 12 back to above the lower placement disk 12. Then, the servo motor 1 is started in the forward direction, and its output shaft drives the double-headed screw 8 to rotate, causing the two linkage plates 9 to move closer to each other, eventually making the two placement disks 12 fit together, thus clamping the object being tested. Then, the rodless cylinder 18 is started, and its slider moves horizontally with the sliding rod 19. Through its cooperation with the curved through groove 17, it... The steering shaft 6 rotates, and after the sliding bar 19 moves to its final position, the support frame 7 rotates 180°, thus exchanging the positions of the two placement discs 12. Then, the servo motor 1 is started in the reverse direction, causing the two linkage plates 9 to move away from each other, eventually separating the two placement discs 12. At this point, the bottom of the object being measured, which was originally facing down, is now facing up. Then, the servo motor 2, which is now located above, is started in the forward direction, rotating the upper placement disc 12 outward. Then, the camera 4 and aperture 5 can continue to be used for visual inspection. In subsequent testing, when it is necessary to exchange the positions of the two placement discs 12 again, the support frame 7 can be rotated 180° by operating the rodless cylinder 18. In addition, during normal testing, in order to ensure that the distance between the camera 4 and the object being tested meets the shooting requirements, the set screw can be rotated in reverse to separate it from the scale bar 23. Then, the lifting screw 21 can be rotated to make the lifting arm 22 carry the camera 4 up or down. The specific value of the rise or fall can be determined by observing the position of the lifting arm 22 on the scale bar 23. After adjusting to the specified position, the set screw can be rotated again.

[0023] Compared with related technologies, the high-precision visual inspection equipment provided by this utility model has the following beneficial effects: This utility model provides a high-precision visual inspection device. By using the set steering shaft 6, the carrier frame 7 can be rotated, thereby exchanging the orientation of the two placement discs 12. This allows the object to be measured inside the placement discs 12 to be flipped, thus ensuring that the bottom of the object can also be visually inspected, improving the comprehensiveness of the inspection and thus improving the accuracy of the inspection results. Furthermore, the cooperation between the curved through groove 17 and the scribing rod 19 ensures that the rotation of the carrier frame 7 always alternates between forward and reverse rotation, preventing entanglement of external wiring and ensuring that the rotation angle of the carrier frame 7 remains consistent.
