[0029] Example 1

[0030] like Figure 1 As shown, a detection rack for myopia control lenses includes: a conveyor belt 1, a CCD camera assembly, a PLC control terminal 3, a mechanical arm 4, a secondary detection terminal and a collection box 5.

[0031] There are two conveyor belts 1, which are arranged parallel to each other, and the conveyor belts 1 are used to convey the eyeglass lenses 2 to be tested;

[0032] CCD camera components, the CCD camera components are arranged above the conveyor belt 1 at intervals, and the CCD camera components are used to collect images of the eyeglass lenses 2;

[0033] A PLC control terminal 3 is arranged between the two conveyor belts 1, and the image of the eyeglass lens 2 collected by the CCD camera assembly is transmitted to the PLC control terminal 3;

[0034] A mechanical arm 4 is arranged between the two conveyor belts 1, and a clamping assembly is provided on the mechanical arm 4;

[0035] A secondary inspection terminal is used to inspect the defective eyeglass lens 2 after being inspected by the CCD camera assembly for re-inspection; and

[0036] The collecting box 5 is provided with a collecting trough with an opening arranged upward, and is used for collecting the defective eyeglass lenses 2 after being inspected by the secondary inspection end.

[0037] In this embodiment, two conveyor belts 1 are provided to continuously convey the eyeglass lens 2 to be inspected to the bottom of the CCD camera assembly and photograph it through the CCD camera assembly. The first CCD detection probe 8 in the CCD camera assembly feeds back the photographed image information of the eyeglass lens 2 to the PLC control terminal 3. The PLC control terminal 3 determines whether the inspected eyeglass lens 2 has defects such as surface depressions. If the eyeglass lens 2 meets the requirements, it is transmitted to the next station through the conveyor belt 1. If it is a defective eyeglass lens 2, the PLC control terminal 3 controls the conveyor belt 1 where the defective eyeglass lens 2 is located to stop rotating, and controls the clamping assembly on the mechanical arm 4 through the PLC control terminal 3 to clamp the defective eyeglass lens 2 to the secondary inspection end for re-inspection. After the second detection, the second CCD detection probe 10 at the secondary detection end feeds back the photographed information of the lens 2 to the PLC control end 3, and the PLC control end 3 determines that the lens meets the requirements, and the mechanical arm 4 and the clamping assembly place the lens 2 on the conveyor belt 1. When the PLC control end 3 determines that the lens does not meet the requirements, the PLC control end 3 controls the mechanical arm 4 and the clamping assembly to place the lens 2 in the collection box 5 for temporary storage, and controls the conveyor belt 1 to continue to rotate through the PLC control end 3. The entire device facilitates rapid detection of the lens 2, and the secondary detection end performs another detection of the lens 2, thereby improving the accuracy of the lens 2 detection and facilitating assembly-line production of the lens 2.

[0038] On the horizontal workbench 6 between the two conveyor belts 1 , the secondary detection end, the collection box 5 and the robot arm 4 are sequentially arranged on the horizontal workbench 6 at intervals along the transmission direction of the conveyor belts 1 .

[0039] like Figure 1 As shown, a support frame 7 is provided above the conveyor belt 1; the CCD camera assembly includes a first CCD detection probe 8, and the first CCD detection probe 8 is arranged on the support frame 7. Specifically, the first CCD detection probe 8 is arranged on the lower end surface of the top of the support frame 7, and the first CCD detection probe 8 is arranged toward the conveyor belt 1.

[0040] The first CCD detection probe 8 transmits the captured image information to the PLC control terminal 3 through information, and the PLC control terminal 3 determines whether the detected lens 2 has defects such as surface depression. If the lens 2 meets the requirements, it is transmitted to the next workstation through the conveyor belt 1. If it is a defective lens 2, the PLC control terminal 3 controls the clamping component on the mechanical arm 4 to clamp the defective lens 2 to the secondary detection terminal for re-inspection.

[0041] The secondary detection end includes a detection table 9 and two second CCD detection probes 10. The two second CCD detection probes 10 are both set toward the detection table 9. The two second CCD detection probes 10 are used to detect the lens 2 in different directions. The detection process is to shoot the lens 2 in different directions through the second CCD detection probes 10, and feed back the shot image information to the PLC control end 3, and the PLC control end 3 determines whether the lens meets the requirements.

[0042] In this embodiment, the second CCD detection probe 10 and the first CCD detection probe 8 are both existing technologies, and their specific models may be Keyence's XG-7000 series, which has the characteristics of fast and high-definition photography. At the same time, the PLC control terminal 3 in this embodiment belongs to the existing technology. Compared with the traditional DCS hardware component, the PLC control terminal 3 has a more flexible structure.

[0043] like Figure 1 and Figure 2 As shown, the clamping assembly includes a horizontal plate 11 and vertical plates 12 arranged on both sides of the horizontal plate 11, a circular frame 13 is fixedly provided between the two vertical plates 12, and a cylinder 14 is provided at one end of the two vertical plates 12 away from each other, and the piston end of the cylinder 14 passes through the vertical plate 12 and the circular frame 13 and is connected to an arc-shaped clamping plate 15 arranged in the circular frame 13. When the cylinder 14 is controlled to extend by the PLC control end 3, the piston end of the cylinder 14 drives the arc-shaped clamping plate 15 to clamp the eyeglass lens 2. When the eyeglass lens 2 needs to be placed, the cylinder 14 contracts to drive the arc-shaped clamping plate 15 and the eyeglass lens 2 to separate.

[0044] A side of the arc-shaped clamping plate 15 away from the piston end of the cylinder 14 is provided with an anti-skid film, and the anti-skid film is used to prevent the arc-shaped clamping plate 15 from detaching when clamping the eyeglass lens 2 .

[0045] The PLC control terminal 3 is disposed on the horizontal workbench 6 , and the first CCD detection probe 8 , the second CCD detection probe 10 , the mechanical arm 4 and the cylinder 14 are all electrically connected to the PLC control terminal 3 .

[0046] Preferably, the PLC control end 3 controls the conveyor belt 1 to rotate. When the first CCD detection probe 8 detects a defective lens 2, the PLC control end 3 controls the conveyor belt 1 to stop rotating, and clamps the lens 2 to the detection table 9 through the arc clamping plate 15 for re-inspection by two second CCD detection probes 10. The second CCD detection probe 10 feeds back the photographed lens 2 information to the PLC control end 3, and the PLC control end 3 determines that the lens meets the requirements, and then the mechanical arm 4 and the clamping assembly place the lens 2 on the conveyor belt 1. When the PLC control end 3 determines that the lens does not meet the requirements, the mechanical arm 4 and the clamping assembly place the lens 2 in the collection box 5 for temporary storage, and the PLC control end 3 controls the conveyor belt 1 to continue rotating.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
