All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout.

Example 1

The detection equipment provided by the embodiment of the invention comprises a feeding bin 1, a feeding assembly, at least one positioning module, at least one detection module, a receiving assembly and at least one receiving bin 6. Fig. 1 is a schematic structural diagram of a detection apparatus according to an embodiment of the present invention, the detection apparatus shown in fig. 1 has 1 feeding bin 1, 2 positioning modules, 2 detection modules, 1 receiving component, and 5 receiving bins 6, the detection apparatus is disposed on a workbench 7, the workbench 7 may be a marble platform, and other platforms meeting the arrangement requirements of the modules, components, and the like may also be used herein.

Referring to fig. 1, the position relationship between the modules and the components specifically includes: the feeding assembly is arranged between the feeding bin 1 and a feeding position and is used for moving the piece to be tested from the feeding bin 1 to at least one feeding position; specifically, the feeding assembly can be a feeding three-axis module, and can also be a manipulator and the like.

Specifically, the feeding assembly comprises a tray feeding assembly 21 and a product feeding assembly 22, wherein the tray feeding assembly 21 is used for taking out a tray filled with a product (to-be-tested piece) from the supply bin and moving the tray to a preset position, and the product feeding assembly 22 is used for taking out the product from the tray at the preset position and placing the product on a positioning assembly 31 at the feeding position.

The positioning module comprises a positioning component 31 and a first moving module 32, and the positioning component 31 can move to a feeding position or a detection position under the driving of the first moving module 32;

Specifically, the detection component includes a color difference detection element 41 and/or a glossiness detection element 42.

Fig. 2(a) is a front view of a dut provided in the prior art, and fig. 2(b) is a top view of a dut provided in the prior art, specifically, as shown in fig. 2(a) and fig. 2(b), the dut is a side button having an arc surface protruding upward, and its detection point is the midpoint of the arc surface, and since the curved surface affects the optical path transmission signals of the chromatic aberration and glossiness detection element, the detection point on the curved surface has a higher requirement for positioning accuracy than the detection point on the plane, and the conventional manual measurement method has low detection efficiency and large detection error, and is not suitable for batch measurement of the duties shown in fig. 2(a) and fig. 2 (b).

It should be noted that fig. 2(a) and 2(b) illustrate the detection point as being at the very center of the convex arc surface, and in some embodiments, the detection point may be other known points.

In the detection process, the chromatic aberration detecting element 41 and the glossiness detecting element have requirements on the detection surface, if the detection surface is a plane, the accuracy of the positioning of the detection point does not have a great influence on the optical path of the detection element, and if the detection surface is a curved surface, the accuracy of the positioning of the detection point influences the optical path transmission signal of the detection element. Therefore, compared with the method for determining the detection point position by adopting manual detection and camera shooting in the prior art, the positioning accuracy of the detection point position can be automatically and accurately determined by positioning the right-angle side.

The X-direction clamping jaw 312 and the Y-direction clamping jaw 315 respectively clamp the piece to be tested, namely, the piece to be tested is positioned to the right-angle side. The detection point position on the arc surface of the piece to be measured is positioned by the right-angle side, so that the positioning accuracy is high, and the accuracy of the measurement result is improved.

When the right-angle side of the workpiece is positioned, the X-direction clamping jaw 312 and the Y-direction clamping jaw 315 approach the workpiece from the X-direction and the Y-direction respectively and push the workpiece to the positioning hole 3111.

Because the to-be-measured piece is light in weight and small in size, when the to-be-measured piece is pushed to the positioning hole 3111 by the clamping

jaws

The detection device is provided with a color difference detection element 41 and a glossiness detection element 42. The operation sequence of the color difference detecting element 41 and the gloss detecting element 42 may be that the color difference detecting element 41 detects at the left detecting station → the gloss detecting element 42 detects at the left detecting station, and simultaneously the color difference detecting element 41 detects at the right detecting station → the gloss detecting element 42 detects at the right detecting station.

That is, the colors of the products in the same tray of the transfer jig 52 are all within the same color difference value range and the glossiness is also within the same glossiness value range. The categories and the number of categories corresponding to different colors are different.
