Description

Technical Field

[0001] This utility model relates to an auxiliary equipment for rubber roller production, and more particularly to a device for detecting appearance defects in rubber roller production. Background Technology

[0002] In the production of rubber rollers, the detection of visual defects is crucial. Traditional inspection methods rely heavily on manual visual sampling, which suffers from low efficiency, susceptibility to subjective factors, and unstable accuracy. Manual inspection struggles to accurately identify minute imperfections and irregularly shaped defects on the surface of rubber rollers, and its speed cannot keep pace with the high-efficiency production rhythm of automated production lines. This results in significant inspection gaps, affecting the continuity of the production process and the stability of finished product quality, making it difficult to meet the high-precision and high-efficiency quality control requirements of modern rubber roller production. Summary of the Invention

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

The discharging end of the feeding assembly is connected to the feeding end of the rotary drive assembly, the discharging end of the rotary drive assembly is connected to the discharging assembly, and the vision inspection assembly is disposed above the rotary drive assembly.

[0023] Furthermore, the feeding assembly includes a roller feed plate 1 to be tested, a roller feed lifting ramp 5, and a lifting assembly. The upper end of the roller feed plate 1 to be tested holds multiple rollers 15 to be calibrated. There are two roller feed lifting ramps 5, which are respectively located below the two ends of the rollers 15 to be calibrated on the discharge side of the roller feed plate 1 to be tested. The lower ends of the two roller feed lifting ramps 5 are connected to the lifting assembly. The discharge side of the roller feed plate 1 to be tested is connected to the rotary drive assembly.

[0024] The rotary drive assembly includes a rubber roller rotation active drive shaft 2, a rubber roller rotation passive drive shaft 3, a roller shaft rotation drive motor 4, and a drive shaft mounting bracket 11. The two ends of the rubber roller rotation active drive shaft 2 and the rubber roller rotation passive drive shaft 3 are respectively rotatably connected to the two drive shaft mounting brackets 11. One end of the rubber roller rotation active drive shaft 2 is connected to the drive end of the roller shaft rotation drive motor 4. The rubber roller 15 to be calibrated is located between the rubber roller rotation active drive shaft 2 and the rubber roller rotation passive drive shaft 3. The discharge assembly is arranged on both sides in front of the rubber roller rotation active drive shaft 2 and the rubber roller rotation passive drive shaft 3. The vision inspection assembly is arranged above the rubber roller rotation active drive shaft 2 and the rubber roller rotation passive drive shaft 3.

[0025] The discharge assembly includes a rubber roller discharge lifting ramp 6 and a rubber roller receiving trough 14. There are two rubber roller discharge lifting ramps 6, which are located below both ends of the rubber roller 15 to be calibrated between the rubber roller rotation active drive shaft 2 and the rubber roller rotation passive drive shaft 3. The lower end of the rubber roller discharge lifting ramp 6 is connected to the lifting assembly. The rubber roller receiving trough 14 is located on one side of the rubber roller rotation passive drive shaft 3.

[0026] Specifically, the lifting assembly includes a lifting inclined plate mounting frame 7, a lifting inclined plate lifting rod 8, a lifting inclined plate lifting cam 9, and a lifting cam drive motor 10. The lower ends of the rubber roller feeding lifting inclined plate 5 and the rubber roller discharging lifting inclined plate 6 are fixedly connected to the upper end of the lifting inclined plate mounting frame 7. The two ends of the lifting inclined plate mounting frame 7 are slidably connected to two lifting inclined plate lifting rods 8. The lifting inclined plate lifting rods 8 are fixedly arranged on both sides of the lifting inclined plate lifting cam 9. The eccentric shaft of the lifting inclined plate lifting cam 9 is rotatably connected to the drive shaft mounting frame 11. The eccentric shaft of the lifting inclined plate lifting cam 9 is drively connected to the lifting cam drive motor 10. The edge of the lifting inclined plate lifting cam 9 is in contact with the lower end surface of the lifting inclined plate mounting frame 7.

[0027] Furthermore, the visual inspection device includes a translational drive rail 12 and an appearance defect detection camera 13. One end of the translational drive rail 12 is fixed to the outside of the active drive shaft 2 or the passive drive shaft 3 of the rubber roller rotation. The drive end of the translational drive rail 12 is connected to the appearance defect detection camera 13, which is located above the active drive shaft 2 and the passive drive shaft 3 of the rubber roller rotation.

[0028] Preferably, the upper surface of the feed plate 1 for the rubber roller to be tested is a sloped structure, and the lower end of the sloped surface of the feed plate 1 for the rubber roller to be tested is... The discharge end of the feed plate 1 of the rubber roller to be tested.

[0029] The working principle of this utility model is as follows:

[0030] In operation, this invention first places multiple rubber rollers to be tested on the feed plate 1. Since the upper surface of the feed plate 1 is a sloping structure with the lower end of the sloping surface being the discharge end, multiple rubber rollers 15 to be tested can be arranged in sequence, one by one located on the discharge side of the feed plate 1, preparing for subsequent feeding.

[0031] When the equipment is started, the lifting cam drive motor 10 begins to operate, driving the lifting cam 9 of the lifting ramp to rotate. As the lifting cam 9 continues to rotate, its edge contacts the lower end face of the lifting ramp mounting frame 7 and generates a lifting force. Under the sliding guidance of the lifting ramp lifting rod 8, the lifting ramp mounting frame 7 drives the rubber roller feeding lifting ramp 5 and the rubber roller discharging lifting ramp 6 to rise synchronously. The rubber roller feeding lifting ramp 5 is inclined, and during its ascent, it steadily lifts both ends of one rubber roller 15 to be tested at the discharge end of the rubber roller feeding plate 1. Under the guidance of the inclined surface of the rubber roller feeding lifting ramp 5, the lifted rubber roller 15 to be tested slides smoothly between the rubber roller rotation active drive shaft 2 and the rubber roller rotation passive drive shaft 3, precisely positioning itself and ready for testing.

[0032] At this time, the roller rotation drive motor 4 starts, and its drive end is connected to the active drive shaft 2 of the rubber roller rotation, driving the active drive shaft 2 of the rubber roller rotation to rotate at a uniform speed. Under the synergistic action of the active drive shaft 2 and the passive drive shaft 3 of the rubber roller rotation, the rubber roller 15 to be calibrated begins to rotate stably and uniformly, ensuring that the surface of the rubber roller can be displayed to the vision inspection component from all directions.

[0033] Simultaneously, the translation drive rail 12 starts, and its drive end is connected to the appearance defect detection camera 13. Driven by the translation drive rail 12, the appearance defect detection camera 13 moves along the axis of the rubber roller 15 to be calibrated, closely following the axis between the active drive shaft 2 and the passive drive shaft 3 of the rubber roller rotation. As the rubber roller 15 continues to rotate, the appearance defect detection camera 13 continuously performs a comprehensive, high-precision scan of the outer surface of the rubber roller, accurately capturing minute surface defects and achieving comprehensive detection of appearance defects.

[0034] Once the appearance defect inspection is complete, the lifting cam drive motor 10 drives the lifting cam 9 of the lifting ramp to rotate again. The rotation direction of the lifting cam 9 changes, and the lifting ramp mounting bracket 7, under the action of the cam, drives the rubber roller discharge lifting ramp 6 to rise. The rubber roller discharge lifting ramp 6 works on the same principle as the rubber roller feed lifting ramp 5. Its rise lifts the rubber roller 15 to be calibrated after inspection, causing it to detach from the support of the rubber roller rotation active drive shaft 2 and the rubber roller rotation passive drive shaft 3, and smoothly fall into the rubber roller collection trough 14 located on one side of the rubber roller rotation passive drive shaft 3, completing the discharge collection.

[0035] It is worth mentioning that while the rubber roller discharge lifting inclined plate 6 lifts the material out, the rubber roller feed lifting inclined plate 5 also rises simultaneously, accurately pushing the next rubber roller to be inspected 15 to the position of the rotary drive component. This achieves seamless connection of the inspection process, greatly improves inspection efficiency, ensures efficient, accurate and stable operation of the appearance defect inspection link in the rubber roller production process, and guarantees the quality of rubber roller products.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
