Description

Technical Field

[0001] This utility model belongs to the field of image detection technology, specifically relating to a device for batch image detection of dial size. Background Technology

[0002] In the manufacturing industries of watches, instruments, automobiles, and home appliances, the dial (or scale, panel) is a crucial visual component. Its dimensional accuracy, such as outer diameter, inner diameter, scale spacing, character size, and hand mounting position, directly affects the product's aesthetics, assembly precision, and the final product's functionality and quality.

[0003] A prior art patent, CN215769389U, describes a watch dial inspection device. This device includes a base with a mounting groove on its upper surface. A telescopic cylinder is fixedly installed inside the mounting groove. A rotating shaft is fixedly installed on one side of the upper surface of the base, and a placement platform is movably installed on the outer surface of the rotating shaft. A sliding groove is formed inside the upper surface of the placement platform. A first fixing mechanism is movably connected to one side of the sliding groove, and a second fixing mechanism is movably connected to the other side. The combination of the first fixing mechanism, the second fixing mechanism, the fixing groove, the sliding groove, and the telescopic spring solves the problems of poor device fixation and inability to adjust according to the watch dial diameter. The combination of the telescopic cylinder and the rotating shaft solves the problem of the inability to adjust the angle between the inspector and the watch dial. However, in practical use, the following shortcomings remain: From a practical standpoint, this patent relies on manual inspection when inspecting watch dials, making close image recognition inspection impossible, reducing inspection accuracy, and preventing the inspection of multiple batches of watch dials, thus reducing inspection efficiency.

[0004] Therefore, there is a need for a batch image detection device for dial size to solve the problems of relying on manual detection and being unable to perform multi-batch detection in existing technologies. Utility Model Content

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a batch image detection device for dial size, including an operating table 1. Support legs 101 are fixedly installed at the four corners of the bottom of the operating table 1. A display device 3 is installed on the upper left side of the operating table 1. An adjustment mechanism 2 is provided on the right side of the display device 3 at the top of the operating table 1. A positioning mechanism 4 is provided on the adjustment mechanism 2. A detection frame 6 is fixedly connected to the top of the operating table 1 and is located below the positioning mechanism 4. A detection mechanism 5 is also provided on the adjustment mechanism 2.

[0024] Further as Figure 1 and Figure 2As shown, it is worth noting that the adjustment mechanism 2 includes two columns 201, which are symmetrically arranged on the upper part of the operating table 1. A slider 202 is slidably mounted on the column 201. A screw 203 is threadedly connected to the slider 202 that slides inside the left column 201. The screw 203 is rotatably mounted inside the column 201 through a bearing. A first motor 204 is fixedly connected to the top of the screw 203. The first motor 204 is fixedly connected to the top of the column 201. A first slide rail 205 is fixedly connected between the two columns 201 and the slider 202. A second slide rail 206 is fixedly connected below the first slide rail 205 and to the slider 202. The first slide rail 205 is connected to the positioning mechanism 4, and the second slide rail 206 is connected to the detection mechanism 5.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the positioning mechanism 4 includes a first slide block 401, which is slidably mounted on the first slide rail 205. Multiple first slide blocks 401 are mounted on the first slide rail 205 and are spaced apart on the first slide rail 205 by the detection mechanism 5. A limiting member 402 is fixedly installed on the top of the first slide block 401 to limit the sliding of the first slide block 401 on the first slide rail 205. A limiting frame 403 is slidably mounted on the first slide block 401. The upper part of the limiting frame 403 is U-shaped and is slidably mounted on the front and rear surfaces of the first slide block 401. Limiting blocks 404 are provided on the front and rear sides of the limiting frame 403. The limiting blocks 404 are correspondingly provided with matching limiting grooves 601 on the detection frame 6 and are slidably mounted in the limiting grooves 601.

[0026] In use, the first motor 204 operates, causing the screw 203 to rotate and drive the slider 202 to slide, which in turn causes the first slide rail 205 and the second slide rail 206 to move. At this time, the operation of the first slide rail 205 and the second slide rail 206 causes the first slide block 401 and the second slide block 501 to slide respectively. The sliding of the first slide block 401 drives the limit frame 403 to slide on the detection frame 6 through the limit block 404, thereby completing the limiting work of the dial. Furthermore, under the sliding of the first slide rail 205, the sliding of the first slide block 401 and the limit frame 403 can adjust the first slide block 401 up and down, so that the limit frame 403 always stays within the detection frame 6 to limit the dial.

[0027] As can be seen from the above working process, by using the adjustment mechanism 2 in conjunction with the positioning mechanism 4, the dial can be automatically limited according to the specifications of the dial, so as to cooperate with the detection mechanism 5 to perform the detection work on the dial. This not only enables batch positioning detection work, but also improves detection efficiency.

[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the detection mechanism 5 includes a second slide block 501, which is slidably mounted on the second slide rail 206. Multiple second slide blocks 501 are slidably mounted on the second slide rail 206, and these multiple second slide blocks 501 are spaced apart on the detection frame 6 via a positioning mechanism 4. An electric telescopic rod 502 is fixedly connected to the upper part of the operating platform 1. The electric telescopic rod 502 is located below the first slide rail 205 via the second slide blocks 501. A mounting frame 503 is fixedly connected to the bottom of the second slide block 501. The mounting frame 503 rotates inwards... A bidirectional screw 504 is provided, and a second motor 505 is fixedly connected to the end of the bidirectional screw 504. The second motor 505 is fixedly connected to the outside of the mounting frame 503. A mounting seat 506 is threadedly connected to the bidirectional screw 504. The mounting seat 506 is slidably disposed within the mounting frame 503. A detection rod 507 is fixedly connected to the bottom of the mounting seat 506. An image acquisition device 508 is installed on the detection rod 507. There are two mounting seats 506 on the bidirectional screw 504, and the two mounting seats 506 are symmetrically arranged on the bidirectional screw 504.

[0029] In use, the position of the mounting frame 503 is adjusted by sliding the second slide 501, so that the image acquisition device 508 can acquire images of the limited dial for inspection. The second motor 505 slides, so that the detection rod 507 and the image acquisition device 508 slide within the mounting frame 503 via the mounting base 506. Thus, the image acquisition device 508 can perform batch image acquisition of the dial, so that high-precision image inspection can be completed by the built-in inspection system, thereby improving inspection efficiency.

[0030] Specifically, the image acquisition device 508 uses an industrial camera (model Baslerac A2500-14uc) paired with a telecentric lens (model Kowa LM8HC). The telecentric lens can eliminate perspective errors and ensure consistent dimensional detection accuracy at different positions such as the dial edge and scale lines. It is also equipped with a ring light source (model Keyence CA-D series, adjustable brightness) to illuminate the dial surface through diffuse reflection, avoiding the impact of reflection on image quality.

[0031] The detection rod 507 is made of carbon fiber instead of traditional metal, which reduces the weight of the detection rod 507 and the load on the second slide 501. A fine-tuning mechanism (including horizontal and vertical fine-tuning screws) is set at the bottom of the detection rod 507, which can manually fine-tune the position of the image acquisition device 508 to ensure that the optical axis of the camera is completely aligned with the center of the dial, thereby further improving the detection accuracy.

[0032] This solution has the following working process: When this device is used, the dials to be tested in batches are placed on the testing frame 6. At this time, the first motor 204 runs, causing the screw 203 to rotate and drive the slider 202 to slide, thereby causing the first slide rail 205 and the second slide rail 206 to move. At this time, through the movement of the first slide rail 205 and the second slide rail 206, the first slide block 401 and the second slide block 501 slide respectively. Through the sliding of the first slide block 401, the limiting frame 403 drives the limiting block 404 to slide on the testing frame 6, thereby completing the limiting work of the dial. And under the sliding of the first slide rail 205, through the first slide block 401 and the limiting frame 403, the dials are also moved. The sliding mechanism allows for vertical adjustment of the first slide block 401, ensuring that the limiting frame 403 remains within the detection frame 6 to limit the dial's position. Simultaneously, the sliding of the second slide block 501 adjusts the position of the mounting frame 503, enabling the image acquisition device 508 to acquire images of the limited dial for inspection. Furthermore, the sliding of the second motor 505 allows the detection rod 507 and the image acquisition device 508 to slide within the mounting frame 503 via the mounting base 506. This allows the image acquisition device 508 to perform batch image acquisition of the dial, facilitating high-precision image detection through the built-in detection system and improving detection efficiency.

[0033] In summary: By using the adjustment mechanism 2 in conjunction with the positioning mechanism 4, the dial can be automatically limited according to its specifications, so as to cooperate with the detection mechanism 5 to perform the detection work on the dial. This not only enables batch positioning detection but also improves detection efficiency. The detection mechanism 5 can perform image detection on the dial, improving the accuracy of the detection, and eliminating the need for manual operation, thus enhancing the automation detection capability.
