Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 3As shown in this embodiment, a visual inspection and positioning device for A-pillar waterproof strips includes a mounting frame 1. Two front conveying rollers 2 and two rear conveying rollers 3 are rotatably mounted on both ends of the mounting frame 1 via bearings. The A-pillar waterproof strip is horizontal when passing between the two front conveying rollers 2 and the two rear conveying rollers 3. The two front conveying rollers 2 or the two rear conveying rollers 3 at the same end are on the same horizontal plane. An upper guide roller 4 is symmetrically mounted on the bottom middle part of the mounting frame 1 via bearings. The A-pillar waterproof strip is in a twisted and flipped state when passing between the two upper guide rollers 4. A mounting base 5 is fixed to the top of the mounting frame 1 by bolts. Visual cameras 6 are mounted on both ends of the mounting base 5 and are electrically connected to a controller 8. Spray nozzles 7 are mounted on both ends of the mounting base 5. The spray nozzles 7 are connected to a pump body and a pigment tank via pipelines. A nozzle is positioned on the mounting base 5 near the rear of the spray nozzle 7. Equipped with a drying component, the sprayed pigment is rapidly dried. A controller 8 is fixedly mounted on one side of the mounting frame 1. The controller 8 contains a control component that matches the conveying speed of the A-pillar waterproof strip. The A-pillar waterproof strip is guided and conveyed sequentially by the front conveying roller 2, the upper guide roller 4, and the rear conveying roller 3. The A-pillar waterproof strip is twisted and flipped in the area between the two upper guide rollers 4. A vision camera 6 above the front conveying roller 2 takes a picture of the A-pillar waterproof strip and performs visual inspection on one side of the A-pillar waterproof strip. Then, the A-pillar waterproof strip is flipped by the rear conveying roller 3, and the other side of the A-pillar waterproof strip is visually inspected. When damage is detected on one side of the A-pillar waterproof strip, the controller 8 controls the pump to operate, spraying the pigment from the pigment tank through the pipe from the nozzle 7. The pigment is sprayed onto the damaged area of ​​the A-pillar waterproof strip, marking the damaged area. The A-pillar waterproof strip can then be removed from this location for easier processing.

[0021] like Figures 1 to 3 As shown, a lower guide roller 9 is installed at the bottom center of the mounting frame 1. The lower guide roller 9 is positioned below the upper guide roller 4. The A-pillar waterproof strip is located between the lower guide roller 9 and the upper guide roller 4. Limiting rods 10 are detachably fixed to the middle of both sides of the mounting frame 1 by bolts. A movable seat 11 is slidably installed between the two limiting rods 10 on the same side. The lower guide roller 9 is rotatably installed between the two limiting rods 10 by bearings. A spring 12 is sleeved on the outer side of the bottom end of the limiting rod 10. One end of the spring 12 is welded and fixed to the lower surface of the movable seat 11, and the other end of the spring 12 is welded and fixed to the inside of the mounting frame 1. The spring 12 is always in a compressed state.

[0022] The A-pillar waterproof strip is guided by two lower guide rollers 9 and positioned between them. The two lower guide rollers 9 also limit the A-pillar waterproof strip in the flipping area, improving the stability of the flipping area. When the A-pillar waterproof strip passes between the two lower guide rollers 9, the movable seat 11 can be pressed down, driving the lower guide rollers 9 away from the upper guide roller 4. At this time, the spring 12 is in an over-compressed state. After the A-pillar waterproof strip passes between the two lower guide rollers 9, the movable seat 11 is removed. The spring 12 resets and pushes the movable seat 11 upward to position the A-pillar waterproof strip between the two lower guide rollers 9, facilitating the assembly of the A-pillar waterproof strip on this device.

[0023] like Figures 1 to 3 As shown, a cylinder 13 is fixedly mounted on the top of the mounting base 5 by bolts. The moving end of the cylinder 13 passes through the mounting base 5 and is fixedly mounted on the mounting block 14. The moving end of the cylinder 13 is slidably connected to the mounting base 5. The nozzle 7 is fixedly mounted in the middle of the mounting block 14.

[0024] The height of the nozzle 7 can be adjusted by controlling the operation of the cylinder 13, thereby adjusting the area and region of the pigment sprayed from the nozzle 7.

One of the nozzles 7 is located above the rear front conveyor roller 2, and the other nozzle 7 is located above the rear rear conveyor roller 3.

[0026] This setup allows for the first horizontal visual inspection of both sides of the A-pillar waterproof strip before horizontal spraying marking, ensuring the horizontality of both the visual inspection and the spraying marking.

[0027] like Figures 1 to 3 As shown, the controller 8 includes an image processing module 15 and a defect detection module 16. The image processing module 15 is used to collect and store the image data captured by the vision camera 6. The image data captured by the vision camera 6 is transmitted to the image processing module 15, and then the collected image data is transmitted to the defect detection module 16. The defect detection module 16 analyzes the collected image data. The controller 8 can also output the data signal processed by the defect detection module 16 to the pump body and the cylinder 13.

[0028] The vision camera 6 takes pictures of the A-pillar waterproof strip and transmits the image data to the image processing module 15 in the controller 8. The collected image data is then sent to the defect detection module 16, which analyzes the collected image data.

[0029] like Figures 1 to 3 As shown, positioning rings 17 are fixedly installed on the outer sides of both the front conveying roller 2 and the rear conveying roller 3 by bolts.

[0030] It can limit the conveying process of the A-pillar waterproof strip to prevent the A-pillar waterproof strip from shifting.

[0031] This utility model provides a visual inspection and positioning device for A-pillar waterproof strips, the specific working principle of which is as follows:

[0032] In use, the device guides and conveys the A-pillar waterproof strip sequentially via the front conveyor roller 2, upper guide roller 4, and rear conveyor roller 3. The A-pillar waterproof strip is then twisted and flipped in the area between the two upper guide rollers 4. A vision camera 6 above the front conveyor roller 2 captures an image of the A-pillar waterproof strip, and the image data is transmitted to the image processing module 15 in the controller 8. The collected image data is then sent to the defect detection module 16. The defect detection module 16 analyzes the collected image data. When damage is detected on one side of the A-pillar waterproof strip, it sends a signal to the controller 8. The controller 8 calculates the location of the damaged area and moves the A-pillar waterproof strip to a specific position. The controller 8 then controls the pump to spray pigment from the pigment tank through the nozzle 7, marking the damaged area. The A-pillar waterproof strip is then flipped over by the rear conveyor roller 3, and the other side of the A-pillar waterproof strip is detected and marked using the same method and principle. This marked side of the A-pillar waterproof strip can then be removed for further processing.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
