With continued reference to fig. 1, the positional relationships between the modules and the components specifically include: the feeding assembly is arranged between the feed bin 1 and the feeding position and is used for moving the part to be tested from the feed bin 1 to at least one feeding position; specifically, the feeding component can be a feeding triaxial module, a manipulator and the like.
Specifically, the loading assembly includes a tray loading assembly 21 and a product loading assembly 22, the tray loading assembly 21 is used for taking out a tray containing a product (to-be-measured piece) from a feed bin and moving the tray to a preset position, and the product loading 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 loading position.
The positioning module comprises a positioning component 31 and a first moving module 32, wherein 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 assembly includes a color difference detection element 41 and/or a glossiness detection element 42.
Fig. 2 (a) is a front view of a piece to be measured provided in the prior art, fig. 2 (b) is a top view of a piece to be measured provided in the prior art, specifically, as shown in fig. 2 (a) and fig. 2 (b), the piece to be measured is a side button with an upwardly convex arc surface, and a detection point is a midpoint of the arc surface.
It should be noted that, the detection points shown in fig. 2 (a) and 2 (b) are the exact centers of the convex arc surfaces, and in some embodiments, the detection points may be other known points.
In the detection process, the color difference detection element 41 and the glossiness detection element have requirements on the detection surface, if the detection surface is a plane, whether the positioning of the detection point position is accurate or not has no great influence on the optical path of the detection element, and if the detection surface is a curved surface, whether the positioning of the detection point position is accurate or not can influence the optical path transmission signal of the detection element.

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

When the right-angle positioning is performed on the workpiece, 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 workpiece to be measured is light in weight and small in size, when the X-direction clamping jaw 312 and the Y-direction clamping jaw 315 push the workpiece to be measured to the positioning hole 3111, the workpiece to be measured may shift, so as to avoid the displacement of the workpiece to be measured, the objective table 311 is further provided with a vacuum flow channel, the positioning hole 3111 is communicated with the vacuum flow channel, the positioning hole 3111 has an open end arranged on the same side as the first clamping assembly and the second clamping assembly, and the open end is arranged between the first clamping assembly and the second clamping assembly.

The long edge Y of fig. 3 is set up and the short edge X is set up.
Specifically, each detection element corresponds to a second moving module, at least one detection element can sequentially move to the same detection position according to a first sequence under the driving of the second moving module, and the same detection element can sequentially move to at least one detection position according to a second sequence under the driving of the second moving module.
With continued reference to fig. 1, in some embodiments, the inspection apparatus is a dual-station fixture, a pair of positioning assemblies 31 are disposed side by side in the X direction, where a pair of positioning assemblies 31 refers to a positioning assembly 31 disposed on a left inspection station and a positioning assembly 31 disposed on a right inspection station, and the part to be inspected moves from a feeding assembly to a swinging assembly in the Y direction.
The detection device is configured 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 glossiness detecting element 42 may be that the color difference detecting element 41 detects at the left detecting station→the glossiness detecting element 42 detects at the left detecting station, and the color difference detecting element 41 detects at the right detecting station→the glossiness detecting element 42 detects at the right detecting station.

It should be noted that the order of operation of the color difference detecting element 41 and the glossiness detecting element 42 is also possible in reverse to the above example, for example, the order of operation of the color difference detecting element 41 and the glossiness detecting element may be such that the glossiness detecting element detects at the left detecting station→the color difference detecting element 41 detects at the left detecting station, and the glossiness detecting element detects at the right detecting station→the color difference detecting element 41 detects at the right detecting station.
The detection equipment provided by the embodiment of the invention is a double-station jig, and the detection efficiency is improved and the labor cost is saved by alternately placing the to-be-detected pieces on a pair of positioning assemblies 31 and alternately detecting the to-be-detected pieces placed on the left detection station and the right detection station.
Specifically, the material receiving component comprises a swinging disc manipulator 51, at least one transfer jig 52 and at least one material receiving component;

In some embodiments, the detection equipment adopts double-station staggered detection and BIN (BIN) swinging disc material receiving by a manipulator, the detection efficiency is high, the detection speed can reach 1.2s/pcs, and the labor cost is saved.
The BIN refers to a category, and the color and the glossiness of the same product cannot be completely the same, so that the detection results of the color difference in the first preset interval and the glossiness in the second preset interval are classified into one category and are put into the same transfer jig 52 disc. Namely, the colors of the products in the same transfer jig 52 disc are all in the same color difference value range, and the glossiness is also in the same glossiness value range. The categories and the number of categories corresponding to different colors are also different.
In some embodiments, the number of positioning assemblies 31 is multiple, and since the positioning assemblies 31 are alternately discharged, the robot reclaiming position can be switched back and forth between the positioning assemblies 31 (i.e. between the left and right inspection stations). Since the to-be-tested pieces are divided into different types according to the detection result, the different types correspond to the different transfer jigs 52, and therefore the material placing position of the manipulator needs to be switched back and forth among the plurality of transfer jigs 52.
