[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets by pressure or centrifugal force and apply them to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying. Therefore, there is a need for an automated spraying equipment based on machine vision.

[0003] When operators perform spraying work, they often use corresponding automated spraying equipment. Although the existing equipment can achieve the purpose of spraying, in actual use, it is necessary to manually clamp and position the workpiece to be sprayed. This operation method increases the labor intensity of the operators and may reduce the efficiency of spraying. In addition, manual assistance is often required for spraying and observation, which reduces its practicality. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This automated spraying equipment based on machine vision operates by having the operator place the workpiece on top of the base and one side of the rubber pad. The positioning pneumatic cylinder is then activated, causing the sleeve to slide between the vertical plates and on the surface of the round rod. The sleeve then moves the slider within the groove, which in turn moves the moving plate. The moving plate then moves the pressure rod, which in turn moves the clamping plate. When the outer surface of the clamping plate contacts the outer surface of the workpiece, the clamping plate moves the pressure rod within the moving plate, compressing the spring. This automatic clamping and positioning method reduces operator workload, improves spraying efficiency, and buffers the clamping force during positioning, thus minimizing damage to the workpiece.

[0013] This automated spraying equipment based on machine vision allows operators to spray paint through an automatic nozzle during daily use, while simultaneously observing the process through a camera module. The storage module stores the observed information, which is then processed and transmitted by the information processing and transmission module. The motor is then activated, causing a threaded rod to rotate. This rod drives a movable plate to slide on the surface of a limit rod, which in turn drives the housing to slide, ultimately causing the automatic nozzle to slide. Simultaneously, a regulating pneumatic cylinder is activated, pushing a push plate to slide. This push plate then drives a moving block to slide inside a long slot, which in turn drives a moving frame to slide. This operation method allows for automated spraying through the automatic nozzle and machine vision observation via a camera module. Attached Figure Description

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.

[0021] Example 1:

[0022] Please see Figures 1-5 An automated spraying device based on machine vision includes a base 1. Vertical plates 2 are fixedly installed on both sides of the top of the base 1. Round rods 3 are fixedly installed between the vertical plates 2. A sleeve plate 4 is movably sleeved on the surface of the round rod 3. A positioning air cylinder 5 is fixedly installed on one side of the vertical plate 2. The output end of the positioning air cylinder 5 passes through the vertical plate 2 and is fixedly connected to one side of the sleeve plate 4. A sliding groove 6 is opened inside the base 1. A slider 7 is movably installed inside the sliding groove 6. The bottom of the slider 7 is fixedly connected to the top of the sleeve plate 4. A movable plate 8 is fixedly installed on the top of the slider 7. A pressure rod 9 is movably installed on one side of the movable plate 8. One side of the pressure rod 9 passes through the movable plate 8 and extends to the left side of the movable plate 8. A clamping plate 10 is fixedly installed on one side of the pressure rod 9. A spring 11 is fixedly installed between the clamping plate 10 and the movable plate 8. A fixing plate 12 is fixedly installed on the top of the base 1. A rubber pad 13 is fixedly installed on one side of the fixing plate 12.

[0023] In this invention, when positioning the sprayed workpiece is required, the workpiece is placed on top of the base 1 and on one side of the rubber pad 13. Then, the positioning pneumatic cylinder 5 is activated. The operation of the positioning pneumatic cylinder 5 will push the sleeve plate 4 to slide between the vertical plates 2 and on the surface of the round rod 3. At this time, the sleeve plate 4 will drive the slider 7 to slide inside the slide groove 6. Then, the slider 7 will drive the moving plate 8 to slide. Subsequently, the moving plate 8 will drive the pressure rod 9 to slide, which in turn will drive the clamping plate 10 to slide. When the outer surface of the clamping plate 10 contacts the outer surface of the workpiece, the clamping plate 10 will drive the pressure rod 9 to slide inside the moving plate 8. Then, the clamping plate 10 will squeeze and compress the spring 11, which can automatically clamp and position the sprayed workpiece and also buffer the clamping force during the clamping and positioning process.

[0024] Example 2:

[0025] Please see Figures 1-5 An automated spraying device based on machine vision is provided. A fixed frame 14 is fixedly installed on the top of the base 1. A long groove 15 is opened on the top of the fixed frame 14. A movable block 16 is movably installed inside the long groove 15. A push plate 17 is fixedly installed on the top of the movable block 16. An installation plate 18 is fixedly installed on the top of the fixed frame 14. An adjustable air pressure cylinder 19 is fixedly installed on one end of the installation plate 18. The output end of the adjustable air pressure cylinder 19 passes through the installation plate 18 and is fixedly connected to one end of the push plate 17.

[0026] In this invention, when the movable frame 20 needs to be adjusted, the adjusting pneumatic cylinder 19 is activated. The operation of the adjusting pneumatic cylinder 19 will push the push plate 17 to slide. Subsequently, the push plate 17 will drive the movable block 16 to slide inside the long groove 15. The inner surface of the long groove 15 and the outer surface of the movable block 16 are both smooth, which allows the movable block 16 to slide more smoothly inside the long groove 15 and reduces the occurrence of jamming. Due to the design of the long groove 15 and the movable block 16, the sliding of the movable frame 20 is more stable. Then, the movable block 16 will drive the movable frame 20 to slide, and the adjustment can be completed.

[0027] Example 3:

[0028] Please see Figures 1-5 An automated spraying device based on machine vision is disclosed. A movable frame 20 is fixedly installed at the bottom of a movable block 16. A threaded rod 21 is rotatably installed inside the movable frame 20. A movable plate 22 is threadedly sleeved on the surface of the threaded rod 21. Limiting rods 23 are fixedly installed at both ends inside the movable frame 20. The outer surface of the limiting rod 23 is movably connected to the inner surface of the movable plate 22. A motor 24 is fixedly installed on one side of the movable frame 20, and the output end of the motor 24 passes through the movable frame 20 and is fixedly connected to one side of the threaded rod 21. A housing 25 is fixedly installed at the bottom of the movable plate 22. An automatic spray head 26 and a camera module 27 are fixedly installed at the bottom of the housing 25. A power module 28, an information processing and transmission module 29, and a storage module 30 are fixedly installed inside the housing 25.

[0029] In this invention, when the automatic spray head 26 needs to be adjusted, spraying can be performed through the automatic spray head 26, followed by visual observation through the camera module 27. Subsequently, the storage module 30 stores the observed information and processes and transmits it through the information processing and transmission module 29. At this time, the motor 24 is started, and the operation of the motor 24 causes the threaded rod 21 to rotate. The threaded rod 21 then drives the movable plate 22 to slide on the surface of the limit rod 23. Subsequently, the movable plate 22 drives the housing 25 to slide, which in turn drives the automatic spray head 26 to slide, thus completing the adjustment.

[0030] Working principle: First, the operator places the workpiece to be coated on top of the base 1 and one side of the rubber pad 13. Then, the positioning pneumatic cylinder 5 is activated. The operation of the positioning pneumatic cylinder 5 will push the sleeve 4 to slide between the vertical plates 2 and on the surface of the round rod 3. At this time, the sleeve 4 will drive the slider 7 to slide inside the slide groove 6. Subsequently, the slider 7 will drive the moving plate 8 to slide. Then, the moving plate 8 will drive the pressure rod 9 to slide, which in turn will drive the clamping plate 10 to slide. When the outer surface of the clamping plate 10 contacts the outer surface of the workpiece, the clamping plate 10 will drive the pressure rod 9 to move inside the moving plate 8. Subsequently, the clamping plate 10 will squeeze and compress the spring 11, thus clamping and positioning the workpiece. Then, it can be sprayed through the automatic spray head 26, and then visually monitored by the camera module 27. After observation, the storage module 30 stores the observed information and processes and transmits it through the information processing and transmission module 29. At this time, the motor 24 is started, and the operation of the motor 24 causes the threaded rod 21 to rotate. The threaded rod 21 then drives the movable plate 22 to slide on the surface of the limit rod 23. Subsequently, the movable plate 22 drives the housing 25 to slide, which in turn drives the automatic spray head 26 to slide. At the same time, the regulating air pressure cylinder 19 is started, and the operation of the regulating air pressure cylinder 19 pushes the push plate 17 to slide. Subsequently, the push plate 17 drives the moving block 16 to slide inside the long groove 15. Subsequently, the moving block 16 drives the moving frame 20 to slide, so that the automatic spray head 26 can be automatically sprayed and observed through machine vision through the camera module 27, etc.
