[0002] Rhinestones are a key decorative component used in jewelry and handicrafts. To ensure the appearance and market value of the product, rhinestones need to be polished during the processing to ensure their smoothness. To ensure the quality of polishing, the smoothness after polishing needs to be inspected. Currently, in addition to manual inspection, image inspection equipment is usually used for inspection.

[0003] In actual testing, the workshop lighting, natural light, and external light sources such as light source radiation can create irregular reflective spots on the polished surface of the rhinestone, which can cover up the scratches, dents, and other defects on the polished surface itself. This can cause the grayscale values ​​of the images captured by the testing camera to be distorted, leading to misjudgments by the computer when performing surface finish analysis and affecting the testing results.

The supplementary lights are fixedly mounted on the inner wall of the detection box.

[0007] Using the above technical solution, visual inspection of water drills can be achieved by using the inspection camera installed inside the inspection box.

[0008] Preferably, square material passage holes are provided through both sides of the detection box, and the material passage holes on the surface of the detection box are the same width as the surface of the conveyor belt. A sliding shielding structure is provided on the surface of the detection box, and the shielding structure separates the detection area inside the detection box from the external light source through a sliding baffle.

[0009] By adopting the above technical solution, the internal detection area of ​​the detection chamber can be separated from the external light source through the sliding shielding structure.

[0010] Preferably, the shielding structure includes a baffle plate, which is slidably mounted on the side surface of the detection box.

[0013] By adopting the above technical solution, the support structure of the water drill can be used to detect the support of the water drill.

[0014] Preferably, the water drill support structure includes a support box, the lower surface of which is fixedly installed on the upper surface of the conveyor belt. The support box is a hollow structure with an open upper surface. A top plate is fixedly installed on the upper surface of the support box. A conical support seat is embedded and fixed on the surface of the top plate. A circular through hole is provided through the surface of the support seat.

[0015] Using the above technical solution, the water drill can be supported by the support base.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the surface finish detection device for rhinestone polished surfaces: 1. This device is equipped with a detection chamber with an open lower surface, forming a relatively closed detection space. At the same time, the square material passage holes on both sides are the same width as the surface of the conveyor belt. The conveyor belt enables the support box connected to the upper surface to move between the inside and outside of the detection chamber, thereby realizing the feeding and discharging of the rhinestone to be detected. With the cooperation of the detection camera, the polishing details of the rhinestone can be detected, realizing the detection of the smoothness of the rhinestone. 2. In this device, the detection chamber is separated from the interior and exterior. With the sliding baffle, the entry of external light sources can be reduced during the detection process, thus improving detection accuracy. When the water drill enters the detection chamber with the conveyor belt, the electric push rod can drive the connecting plate and the baffle to slide, thereby blocking the material passage hole and separating the detection area from the external environment. The supplementary lights symmetrically arranged on the inner wall of the detection chamber provide illumination, avoiding interference from changes in the brightness of external light sources on the detection results. 3. This device is equipped with a support box and a surface support seat to support the water drill. The conical support seat can position and support the water drill during the testing process. The hollow support box contains a first air bladder and a second air bladder connected together. The movement of the pressure plate moves the airflow inside the first air bladder and the second air bladder. After the water drill is tested, pressing down on the second air bladder allows the airflow to be blown out from the circular through hole on the surface of the support seat. The airflow causes the water drill to bounce upward, which is convenient for unloading after the water drill is tested. Attached Figure Description

During the testing process, the water drill is placed on the upper surface of the support base 13. The motor 3 is started, and the motor 3 drives the conveyor belt 2 to move. The conveyor belt 2 drives the support box 11 on the surface to move. The baffles 10 on the inner surface of the base 1 are located on both sides of the testing box 4. The lower surface of the baffles 10 contacts the conveyor belt 2, which can restrict the movement of the support box 11. The support box 11 carrying the water drill is fed into the interior through the square material passage hole on one side of the testing box 4. After the conveyor belt 2 carries the support box 11 completely into the detection chamber 4, the motor 3 is turned off. The support box 11 is stationary below the detection camera 5. The electric push rods 9 are controlled by the computer algorithm. The two electric push rods 9 push the connecting plate 8 downward in sync, which drives the two baffles 7 to slide along the side surface of the detection chamber 4 until the material passage holes on both sides are completely blocked, forming a relatively closed detection space to reduce interference from external light sources. The supplementary light 6 is turned on to provide illumination for the detection process. The detection camera 5 takes pictures of the polished surface of the rhinestone at a preset frequency.

[0024] Two baffles 10 are fixedly installed on the inner surface of the base 1. The two baffles 10 are located on both sides of the detection box 4. The lower surface of the baffles 10 contacts the upper surface of the conveyor belt 2.

The electromagnet 18 is fixed to the slide rod 17, and the magnetic block 19 is fixed to the upper surface of the pressure plate 16. like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, when the support box 11 moves to the end of the conveyor belt 2, the electromagnet 18 is activated. The electromagnet 18 is energized and generates magnetism that attracts the magnetic block 19. Under the attraction of the magnetic block 19, the electromagnet 18 drives the slide bar 17 to move downward. The slide bar 17 drives the pressure plate 16 to move downward and squeeze the second airbag 15. After being compressed, the gas in the second airbag 15 flows into the first airbag 14 through the connecting channel. Finally, it blows air upward through the circular through hole on the surface of the support seat 13, which bounces the water drill off the conical support seat 13, thereby assisting the water drill to separate from the support seat 13 for material discharge. After the material is discharged, the electromagnet 18 is de-energized and the magnetism disappears. The first airbag 14 and the second airbag 15 reset due to their own compression structure, driving the pressure plate 16 and the slide bar 17 back to the initial position, waiting for the next material feeding. The conveyor belt 2 rotates in the opposite direction, and the support box 11 returns to the feeding area to enter the next round of water drill inspection.
