Description

Technical Field

[0001] This utility model belongs to the field of insulator inspection, and in particular relates to a visual inspection structure for steel feet. Background Technology

[0002] During the assembly of insulator modules, inserting steel feet into the insulator is also a step in the insulator assembly process. Before inserting the steel feet, it is necessary to inspect their appearance. Usually, this is done manually to check for any damage. However, manual operation is inefficient. Due to the small size of the steel feet and the large number of them to be inspected, it is easy to miss some. In addition, manual identification is prone to misjudgment. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a steel foot visual inspection structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steel-foot visual inspection structure includes a support shaft. A camera mounting bracket and a steel-foot mounting bracket are sleeved on the outer surface of the support shaft. A detection camera is mounted on the camera mounting bracket. At least one of the camera mounting bracket and the steel-foot mounting bracket is slidably mounted on the support shaft. A placement block is mounted on the steel-foot mounting bracket. A placement cavity is provided inside the placement block. A limiting piece is provided at the opening of the placement cavity and slides on the placement block. The limiting piece can be close to or away from the center of the placement cavity.

[0006] In the above-mentioned steel foot visual inspection structure, the placement frame includes a bracket fixedly mounted on the base plate, the bracket is provided with a support plate, and the lateral movement structure includes a moving belt mounted on the support plate, the moving belt is placed around the support plate, and the moving belt is connected to the lateral drive structure.

[0007] In the above-mentioned steel foot visual inspection structure, the limiting plate includes a base plate, which is attached to and slidably connected to the placement block. The base plate is provided with a sliding groove, and a limiting shaft disposed on the placement block is slidably disposed in the sliding groove. The base plate is connected to a linear actuator.

[0008] In the above-mentioned steel foot visual inspection structure, the limiting plate also includes an extension plate fixedly connected to the base plate. The extension plate extends outward along the center line of the placement cavity and has a top plate at its extended end. The placement direction of the top plate is perpendicular to the center line of the placement cavity.

[0009] In the aforementioned steel-foot visual inspection structure, the camera mounting bracket is equipped with a light shield, the light shield has an observation hole, and the inspection camera is placed at the observation hole.

[0010] In the aforementioned steel foot visual inspection structure, the steel foot placement frame is provided with a retaining ring, the retaining ring has a cavity inside, and the retaining ring can abut against the light-blocking cover.

[0011] In the aforementioned steel foot visual inspection structure, the retaining ring is connected to the placement block via an extension shaft, and a light-entry channel is provided between the retaining ring and the placement block.

[0012] In the above-mentioned steel foot visual inspection structure, the extension shaft is slidably connected to the retaining ring, and a spring can be sleeved on the outer surface of the extension shaft. The two ends of the spring abut against the retaining ring and the placement block respectively, and the spring is in a compressed state.

[0013] In the above-mentioned steel foot visual inspection structure, the steel foot placement frame is equipped with a fine-tuning linear driver, and the output shaft of the fine-tuning linear driver is connected to the placement block.

[0014] In the above-mentioned steel foot visual inspection structure, the steel foot placement frame is provided with a limiting block, the limiting block is provided with a limiting groove, the bottom of the placement block is provided with a limiting piece, and the limiting piece extends into the limiting groove.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. The detection camera is placed close to the steel foot and performs shape detection on the steel foot. The camera performs multi-directional detection and identification of the steel foot. Compared with manual identification, the error rate and misjudgment rate are reduced, and the work efficiency is improved.

[0017] 2. The linear drive moves the abutment, which in turn moves the limiting plate closer to the steel foot. This places the limiting plate on the side of the placement cavity to restrict the steel foot and prevent it from falling out of the cavity. In addition, the limiting shaft groove helps prevent the limiting plate from moving too far, which could damage the steel foot.

[0018] 3. During camera inspection, the light shield can prevent the inspection camera from photographing parts that are not part of the inspection structure, thus preventing the inspection camera from failing to identify them or misjudging them due to the identification of other parts, thereby reducing the error rate and misjudgment rate.

[0019] 4. When the camera mount and the steel foot mount approach each other, the light shield will come into contact with the retaining ring. The light shield is slidably connected to the retaining ring through the extension shaft, which prevents the light shield from impacting the retaining ring and causing damage to the parts.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] This embodiment provides a steel leg visual inspection structure, combined with Figure 1-4 As shown, the device includes a support shaft 10. A camera mounting bracket 11 and a steel foot mounting bracket 12 are fitted onto the outer surface of the support shaft 10. A detection camera 13 is mounted on the camera mounting bracket 11. At least one of the camera mounting bracket 11 and the steel foot mounting bracket 12 is slidably mounted on the support shaft 10. A placement block 14 is mounted on the steel foot mounting bracket 12. A placement cavity 15 is provided inside the placement block 14. A limiting piece 16 that slides on the placement block 14 is provided at the opening of the placement cavity 15. The limiting piece 16 can be close to or away from the center of the placement cavity 15.

[0027] In this embodiment, the steel foot is placed inside the placement cavity 15. The limiting plate 16 is moved closer to the center of the placement cavity 15 by moving the limiting plate 16, thereby restricting the steel foot and preventing it from falling out of the placement cavity 15. One or both of the camera placement bracket 11 and the steel foot placement bracket 12 are connected to a linear actuator. Under the operation of the linear actuator, the camera placement bracket 11 and the steel foot placement bracket 12 are brought closer to each other, so that the detection camera 13 is close to the steel foot and performs shape detection on the steel foot. By performing multi-directional detection and identification of the steel foot through the camera, the error rate and misjudgment rate are reduced compared with manual identification, thus improving work efficiency.

[0028] The limiting sheet 16 includes a base sheet 17, which is attached to and slidably connected to the placement block 14. The base sheet 17 is provided with a groove 18, and a limiting shaft disposed on the placement block 14 is slidably disposed in the groove 18. The base sheet 17 is connected to a linear actuator.

[0029] In this embodiment, when the steel foot is not placed, the limiting piece 16 is located at the far end away from the placement cavity 15. After the steel foot is placed in the placement cavity 15, the abutment piece 17 is moved by the operation of the linear actuator, thereby moving the limiting piece 16 closer to the steel foot. This allows the limiting piece 16 to be located on the side of the placement cavity 15 to limit the steel foot and prevent it from falling out of the placement cavity 15. In addition, the cooperation of the limiting shaft slide groove 18 can prevent the limiting piece 16 from moving too far and causing wear and damage to the steel foot.

[0030] The limiting piece 16 also includes an extension piece 19 fixedly connected to the bottom piece 17. The extension piece 19 extends outward along the center line of the placement cavity 15 and has a top piece 20 at its extended end. The placement direction of the top piece 20 is perpendicular to the center line of the placement cavity 15.

[0031] In this embodiment, the extension piece 19 is used to extend the limiting length located on the side of the steel foot, and the top piece 20 is used to limit the top of the steel foot away from the placement block 14, thereby limiting the steel foot by the end and side of the steel foot to prevent it from falling.

[0032] The camera mounting bracket 11 is equipped with a light shield 21, and the light shield 21 is equipped with an observation hole 22. The detection camera 13 is placed at the observation hole 22.

[0033] In this embodiment, when the camera is taking pictures for detection, the light shield 21 can prevent the detection camera 13 from taking pictures of parts that are not in the detection structure, which would cause the detection camera 13 to fail to identify or misidentify other parts, thereby reducing the error rate and misjudgment rate.

[0034] The steel foot holder 12 is provided with a retaining ring 23, and the retaining ring 23 has a cavity 24 inside, and the retaining ring 23 can abut against the light shield 21.

[0035] In this embodiment, the detection camera 13 is further configured to only capture images of the steel foot through the cavity 24, thereby preventing the detection camera 13 from capturing images of parts other than those in the detection structure, which could lead to recognition failure or misjudgment due to the identification of other parts, thus reducing the error rate and misjudgment rate.

[0036] The baffle ring 23 is connected to the placement block 14 via the extension shaft 25, and a light-entry channel is provided between the baffle ring 23 and the placement block 14.

[0037] In this embodiment, the light inlet channel is used to allow external light to illuminate the steel foot, so that the inspection camera 13 can clearly photograph the steel foot in a bright environment for inspection.

[0038] The extension shaft 25 is slidably connected to the retaining ring 23. A spring can be sleeved on the outer surface of the extension shaft 25. The two ends of the spring abut against the retaining ring 23 and the placement block 14 respectively. The spring is in a compressed state.

[0039] In this embodiment, as the camera mount 11 and the steel foot mount 12 approach each other, the light shield 21 will abut against the retaining ring 23. The light shield 21 is slidably connected to the retaining ring 23 through the extension shaft 25, which ensures that the light shield 21 will not collide with the retaining ring 23 and cause damage to the parts during the process of abutting against the retaining ring 23.

[0040] The steel foot mounting bracket 12 is equipped with a fine-tuning linear driver 26, and the output shaft of the fine-tuning linear driver 26 is connected to the mounting block 14.

[0041] In this embodiment, during the shooting process, the linear driver 26 is finely adjusted to move the placement block 14 with the steel foot a short distance, so that the detection camera 13 can better focus on the steel foot and prevent blurry images.

[0042] The steel foot placement frame 12 is provided with a limiting block 27, the limiting block 27 is provided with a limiting groove 28, and the bottom of the placement block 14 is provided with a limiting piece 29, the limiting piece 29 extending into the limiting groove 28.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0044] Although this article frequently uses terms such as support shaft 10, camera mount 11, steel foot mount 12, detection camera 13, mounting block 14, mounting cavity 15, limiting plate 16, film 17, sliding groove 18, extension plate 19, top plate 20, light shield 21, observation hole 22, retaining ring 23, cavity 24, extension shaft 25, fine-tuning linear actuator 26, limiting block 27, limiting groove 28, and limiting plate 29, these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
