Description

Technical Field

[0001] The present invention relates to the field of surface detection of earphone charging boxes, and in particular to a device for detecting surface defects of earphone charging boxes. Background Art

[0002] The headphone charging box is a portable charging device designed specifically for Bluetooth headphones. It is usually in a small box-shaped design with an integrated charging circuit and battery. It is used to store and provide power for Bluetooth headphones. When the user's Bluetooth headphones are exhausted, just put the headphones into the charging box and fix them by magnetic suction or slots. The charging process will automatically start without any additional operation, which greatly facilitates the user experience.

[0003] At present, during the production process of earphone charging boxes, the detection of surface defects mainly relies on manual visual inspection or traditional optical inspection equipment. Although the manual inspection method is flexible, it has problems such as low detection efficiency, strong subjectivity, and high missed detection rate due to fatigue. It is difficult to meet the needs of large-scale production. Traditional optical inspection equipment usually uses fixed cameras for shooting. Due to the complex features such as curved surfaces and reflective areas on the surface of the charging box, it is difficult to fully cover all inspection areas with a single-angle shooting, which easily leads to the missed detection of minor defects. In addition, the existing inspection equipment generally lacks high-precision positioning mechanisms, which causes the charging box to shift in position during the inspection process, further affecting the inspection accuracy. These technical defects are mainly due to the inability of existing equipment to achieve multi-angle and all-round image acquisition, and the lack of a stable and reliable positioning mechanism, which restricts the improvement of inspection accuracy and efficiency.

[0025] Working principle: First, the staff places the charging box body 4 to be tested on the conveyor belt 2 in turn, starts the drive motor 3, and makes the drive motor 3 drive the conveyor belt 2 to rotate and move. The conveyor belt 2 moves the first charging box body 4 to the inner side of the U-shaped frame 6. At this time, the drive motor 3 stops running, and the two electric push rods 14 run. The electric push rods 14 push the push frame 15 to move along the inner side of the U-shaped frame 13. The push frame 15 pushes the first elastic pressure rod 16 and the four second elastic pressure rods 17 to be close to the charging box body 4. The four second elastic pressure rods 17 press against the rounded corners of the charging box body 4 through the pressure balls 28, and the first elastic pressure rod 16 presses against the outer side of the charging box body 4 through the pressure balls 28, completing the clamping and positioning of the charging box body 4. Subsequently, the electric telescopic rod 12 runs, and the electric telescopic rod 12 pulls the movable plate 11 to move upward along the outside of the slide 10. The movable plate 11 pulls the rotating drum 18 upward through the sleeve rod 19 and compresses the telescopic airbag 29, so that the air in the telescopic airbag 29 is discharged from the nozzle 8 through the hose. The nozzle 8 sprays and cleans the charging box body 4. The rotating drum 18 drives the U-shaped frame 6 to move upward, so that the charging box body 4 in the U-shaped frame 6 moves upward. When the gear 22 contacts the rack 21 on the L-shaped support plate 20, the rack 21 drives the rotating drum 18 to rotate through the gear 22, so that the rotating drum 18 is in a rotating state during the upward movement, and the rotating drum 18 drives the U-shaped frame 6 to rotate synchronously, so that the charging box body 4 rotates synchronously The rotating drum 18 rotates and moves. At the same time, the detection host 33 starts the two laser detection probes 5, so that the laser detection probes 5 perform surface defect detection on the charging box body 4 in the rotating state, and the nozzle 8 can fully clean the charging box body 4 in the rotating state to prevent dust and impurities from affecting the accuracy of the detection of the laser detection probe 5. Then, the prismatic rod 23 in the rotating drum 18 contacts the inclined surface of the baffle 27. When the spherical block 25 moves to the side of the baffle 27, the reaction force of the baffle 27 on the spherical block 25 is used to push the prismatic rod 23 to move along the inner side of the rotating drum 18. The prismatic rod 23 drives the baffle frame 7 to move synchronously, so that the baffle frame 7 stretches the tension spring 24, and the baffle frame 7 can push the charging box body 4. Move and replace the clamping point of the pressure ball 28 on the charging box body 4, so that the laser detection probe 5 can fully detect the charging box body 4, and then, the electric telescopic rod 12 pushes the movable plate 11 to reset downward, so that the charging box body 4 is in contact with the conveyor belt 2 again, and the electric push rod 14 pulls the first elastic pressure rod 16 and the second elastic pressure rod 17 away from the charging box body 4 through the push frame 15. Finally, the electric telescopic rod 12 pulls the movable plate 11 upward again, so that the U-shaped frame 6 is away from the charging box body 4, so that the conveyor belt 2 transports the charging box body 4 that has completed the inspection, and moves the next charging box body 4 to be inspected to the bottom of the U-shaped frame 6, thereby achieving the effect of comprehensive detection and facilitating continuous detection of the charging box body 4.
