Description

Technical Field

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

[0002] In everyday life, label visual inspection is a quality control method that uses machine vision technology to comprehensively inspect product labels. It is mainly used in industrial production to ensure the accuracy of label position, pattern, text and color. It mainly uses industrial cameras to capture label images, and after preprocessing (such as noise reduction and contrast enhancement), it uses feature extraction and machine learning algorithms to analyze image information and finally output the inspection results.

[0003] Currently, label visual inspection equipment is mainly used in production line workshops, and industrial cameras and other visual inspection equipment are exposed to the outside for a long time. Dust and oil gradually adhere to the surface of the lens. In order to ensure the smooth operation of label visual inspection, frequent cleaning is required. However, if manual cleaning is carried out regularly, it will consume too much energy and cannot be done immediately. If the cleaning is too frequent, it will cause lens wear and reduce the service life. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a label visual inspection device, including a workbench 1, a support frame 2 fixedly connected to one side of the workbench 1, a fixed box 3 fixedly connected to the inner side of the support frame 2, an air cylinder 4 fixedly connected to the inner side of the fixed box 3, a piston 5 slidably connected inside the air cylinder 4, a first spring 7 fixedly connected between one side of the piston 5 and one side inside the air cylinder 4, one side of the piston 5 located inside the first spring 7 and fixedly connected to an elliptical rod 6, an air inlet one-way valve 8 fixedly connected to one side of the air cylinder 4, a fixed cylinder 10 fixedly connected to the inner side of the fixed box 3, an exhaust one-way valve 9 fixedly connected to one side of the air cylinder 4, and a fixed cylinder 10... A telescopic airbag 11 is fixedly connected to one side of the fixed cylinder 10. A telescopic tube is fixedly connected between the telescopic airbag 11 and the exhaust one-way valve 9. A second spring 12 is fixedly connected between one side of the telescopic airbag 11 and one side of the fixed cylinder 10. One side of the telescopic airbag 11 is located inside the second spring 12 and is fixedly connected to a solenoid valve 13. A trigger rod 14 is fixedly connected to one side of the telescopic end of the telescopic airbag 11. Two tactile switches 15 are fixedly connected to one side of the fixed box 3. The above configuration includes an air cylinder 4, a piston 5, a first spring 7, an elliptical rod 6, an intake one-way valve 8, a fixed cylinder 10, an exhaust one-way valve 9, a telescopic airbag 11, and a second spring 12. The solenoid valve 13, trigger rod 14, and tactile switch 15 can sequentially push the elliptical rod 6 through multiple elliptical heads 23. The moving elliptical rod 6 drives the piston 5 to inflate the telescopic airbag 11. This causes the telescopic end of the airbag 11 to trigger the trigger rod 14 to contact the tactile switch 15 at its endpoint, thus initiating the cleaning process. Based on the scheduled cleaning of the industrial camera 16 within a set working time, no manual inspection is required, ensuring the cleanliness of the industrial camera 16 lens and preventing excessive wear caused by excessive wiping. Furthermore, during the cleaning process… The solenoid valve 13 is opened to expel the gas from the telescopic airbag 11. When the gas in the telescopic airbag 11 is completely expelled, the trigger rod 14 can be moved to the initial position. The trigger rod 14 can then touch the touch switch 15 at the initial position and the touch switch 15 at the threshold position to set the cleaning time, preventing over-cleaning due to prolonged cleaning time. The detection results are fed back to the first cylinder 17 and the first motor 19, which can automatically start the cleaning operation when the detection results are deviated. Regular and irregular cleaning operations can be performed alternately to ensure the accuracy of the detection results.

[0019] The workbench 1 is fixedly connected to a second motor 21. The output end of the second motor 21 is fixedly connected to a rotating table 22. The rotating table 22 is fixedly connected to multiple third motors 26 at equal intervals in a circle. The output ends of the multiple third motors 26 are all fixedly connected to a fixed base 27, which can adjust the direction of the detection device placed on the fixed base 27, making it convenient for detection work.

[0020] The inner side of the rotating table 22 is located above the fixed base 27 and is rotatably connected to the rotating base 24. The bottom of the rotating base 24 is fixedly connected to the second cylinder 25, which can control the second cylinder 25 to fix the detection device placed on the fixed base 27. When the third motor 26 rotates the fixed base 27, it can drive the rotating base 24 to rotate, thus ensuring that the position of the detection device is stable during detection.

[0021] An elliptical head 23 is fixedly connected to the outer side of the rotating stage 22 on one side of the fixed base 27. The elliptical head 23 corresponds to the number of detection devices, and the counting work is completed by moving the elliptical rod 6 through the elliptical head 23.

[0022] A first cylinder 17 is fixedly connected to the inner side of the support frame 2. A fixed groove column 18 is fixedly connected to the output end of the first cylinder 17. A first motor 19 is fixedly connected inside the fixed groove column 18. A cleaning brush plate 20 is fixedly connected to the output end of the first motor 19, which can wipe the lens of the industrial camera 16.

[0023] An industrial camera 16 is fixedly connected to the inner side of the support frame 2, enabling inspection work to be carried out through the industrial camera 16.

[0024] Specifically, the object to be inspected is placed on the fixed seat 27, the second cylinder 25 is controlled to fix the object, and the second motor 21 is controlled to rotate the rotating table 22 to inspect the object one by one. The fixed seat 27 is rotated by the third motor 26, and the object can drive the rotating seat 24 to complete the turning operation. The object can be inspected by the industrial camera 16, and the elliptical head 23 corresponding to the number of objects pushes the elliptical rod 6 to move. The moving elliptical rod 6 can drive the piston 5 to stretch the first spring 7, and through the exhaust one-way valve 9, it can push the telescopic airbag 11. The air cylinder 4 is inflated. When the elliptical rod 6 is no longer pushed, the stretched first spring 7 drives the piston 5 to return to its original position, inflating the air cylinder 4 through the air inlet check valve 8. This process is repeated to inflate the telescopic airbag 11 to the set threshold air volume. When the telescopic end of the telescopic airbag 11 moves, it can slide within the fixed cylinder 10 and compress the second spring 12. The telescopic end of the telescopic airbag 11 can drive the trigger rod 14 to move, setting the tactile switch 15 on one side of the trigger rod 14 at the initial position as the first tactile switch 15. The final position of the trigger rod 14 is then set to the first tactile switch 15. Switch 15 is set as a second tactile switch. When the gas volume inside the telescopic airbag 11 reaches a threshold, the trigger rod 14 triggers the second tactile switch 15. The tactile switch 15 controls the first cylinder 17 to align the fixed groove post 18 with the industrial camera 16 at the same horizontal position. Then, it controls the first motor 19 to rotate the cleaning brush plate 20 so that the cleaning brush plate 20 can clean the lens of the industrial camera 16. The tactile switch 15 also controls the solenoid valve 13 to release gas. The compressed second spring 12 can push the trigger rod 14 on one side of the telescopic end of the telescopic airbag 11. When the trigger lever 14 triggers the first tactile switch 15, the first motor 19 can be stopped by the first tactile switch 15, and the first cylinder 17 can be controlled to drive the fixed groove column 18 to reset, thereby stopping the cleaning work. In this way, the amount of gas in the telescopic airbag 11 can be used as a threshold for the cleaning work time to prevent the cleaning time from being too long. The information is fed back to the first cylinder 17 and the first motor 19 through the detection results. When the detection results are deviated, the cleaning work can be automatically started, and regular and irregular cleaning work can be carried out alternately.
