Description

Technical Field

[0001] This utility model relates to the field of visual detection technology, and in particular to a visual positioning device. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection refers to the process of converting the captured target into an image signal through machine vision products and transmitting it to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, the signal is converted into a digital signal. The image system performs various operations on these signals to extract the target's features and then controls the on-site equipment based on the judgment results.

[0003] For example, patent (CN221630782U) discloses a visual positioning device for visual inspection, including a worktable. The top of the worktable is equipped with a positioning adjustment mechanism for the visual positioning device for visual inspection. The positioning adjustment mechanism includes an outer column, and limit grooves are evenly opened on both sides of the inner wall of the outer column. By setting the positioning adjustment mechanism, this utility model can enable the device to perform positioning adjustment processing on the camera for visual inspection during later use, thereby making it more convenient to perform comprehensive inspection of items.

[0004] When using the above technology, the following technical problems were found in the existing technology: The existing technology uses a positioning adjustment mechanism to adjust the positioning of the camera for visual inspection, which makes it easier to conduct comprehensive inspection of items. However, this device is not convenient for adjusting and limiting products of different sizes, thereby reducing the stability and practicality of the device for fixing products. Therefore, we designed a visual positioning device to provide another technical solution to the above technical problems. Utility Model Content

The two sides of the outer side of the positive and negative threaded rods are respectively threaded to the threaded blocks. A servo motor is mounted on one side of one of the limit blocks. The output end of the servo motor is fixed to the positive and negative threaded rods.

[0011] In a preferred embodiment of the visual positioning device provided by this utility model, the support column is provided with a lifting mechanism for driving the rack block to move up and down. The lifting mechanism includes a transmission gear, a connecting rod and a servo motor.

[0026] Example 1

[0027] Please refer to Figures 1-4 A visual positioning device includes an operating table 1. Several electric rollers 3 are installed inside the operating table 1. Support columns 2 are fixed on both sides of the top of the operating table 1. A rack block 8 is slidably connected to the inner side of the support column 2. A vertical plate 5 is fixed to the top of the rack block 8. A slide block 6 is slidably connected to the bottom of the vertical plate 5. A detection instrument 7 is installed below the slide block 6. A fixing block 11 is fixed to the end of the two support columns 2 that are close to each other. A slider 12 is slidably connected inside the fixing block 11. A clamping plate 4 is fixed to one end of the slider 12. A protective pad is fixed to the end of the two clamping plates 4 that are close to each other. A clamping mechanism for driving the two clamping plates 4 to move is provided at the bottom of the operating table 1.

[0028] Specifically, the product is first placed above the electric roller 3, and then the electric roller 3 drives the product to be conveyed directly below the vertical plate 5. Then, the clamping mechanism is activated to drive the two clamping plates 4 to press the product in a direction that brings them closer together, so that the clamping plates 4 position the product, thereby ensuring that the detection position of each product remains unchanged. Finally, the slide 6 and the vertical plate 5 reciprocate, and then the slide 6 drives the detection instrument 7 to detect the product, so as to improve the accuracy of the detection instrument 7.

[0029] The clamping mechanism includes a connecting block 13, a threaded block 14, a linkage rod 15, a forward and reverse threaded rod 16, and a servo motor 17. Both ends of the bottom of the clamping plate 4 are fixed with connecting blocks 13. The bottom end of the connecting block 13 is rotatably connected with the linkage rod 15. The end of the linkage rod 15 away from the connecting block 13 is rotatably connected with the threaded block 14. Limit blocks are fixed on both sides of the bottom of the operating table 1. The inside of the limit block is rotatably connected with the forward and reverse threaded rod 16. The two sides of the outside of the forward and reverse threaded rod 16 are respectively threaded to the threaded block 14. One side of one of the limit blocks is equipped with a servo motor 17. The output end of the servo motor 17 is fixed to the forward and reverse threaded rod 16.

[0030] When product testing is required, the product is placed above the electric roller 3. The servo motor 17 is started to drive the positive and negative threaded rod 16 to rotate, which causes the positive and negative threaded rod 16 to drive the two threaded blocks 14 to move towards each other. The threaded blocks 14 drive the linkage rod 15, the connecting block 13 and the clamping plate 4 to clamp and position the product. The two clamping plates 4 limit the product to improve the accuracy of each product testing.

[0031] The support column 2 is equipped with a lifting mechanism for driving the rack block 8 to move up and down. The lifting mechanism includes a transmission gear 9, a connecting rod 10 and a servo motor 18. The transmission gear 9 is rotatably connected to the inside of the support column 2. One side of the transmission gear 9 is meshed with the rack block 8. The connecting rod 10 is rotatably connected to the inside of the support column 2. Both sides of the connecting rod 10 pass through the support column 2 and are fixed to the transmission gear 9. One side of one of the support columns 2 is equipped with a servo motor 18. The output end of the servo motor 18 is fixed to the connecting rod 10.

[0032] When some products are too tall, the servo motor 18 is started to drive the linkage 10 to rotate, which in turn drives the two transmission gears 9 to rotate synchronously. The transmission gears 9 drive the rack block 8, the vertical plate 5, the slide 6 and the detection instrument 7 to adjust according to the height of the product.

[0033] The visual positioning device provided by this utility model is used as follows:

[0034] Working principle: First, the product is placed above the electric roller 3. Then, the electric roller 3 drives the product to be conveyed directly below the vertical plate 5. Then, the servo motor 17 is started to drive the positive and negative threaded rod 16 to rotate. The positive and negative threaded rod 16 drives the two threaded blocks 14 to move towards each other. The threaded blocks 14 drive the linkage rod 15, the connecting block 13 and the clamping plate 4 to clamp and position the product. Thus, the two clamping plates 4 limit the product to improve the accuracy of each product inspection.
