In order to better understand the functional implementation of the product appearance detection, the detailed characteristics of each component are further shown below.
As a bottom support for the entire apparatus, the above-described stage assembly 1 shown in FIGS. 2 and 3 has a spatially planar base 1 a. The surface of the base 1a is assumed to correspond to the XY plane of the three-dimensional coordinate system. The structure of the base assembly 1 is: the surface of the base 1a is sequentially connected with a Y-axis sliding module 1b, a DD motor 1c and a rotary worktable 1d which are independently controlled to act from bottom to top, and the rotary worktable 1d can alternatively bear a product 5 to be tested and rotate along the Y-axis linearly and parallel to the central line of the Z-axis. Wherein the driving cable buses of the DD motor 1c and the Y-axis sliding module 1b are connected to the main control unit of the device. In order to facilitate electrical and pneumatic wiring, a first drag chain 11b for wiring is arranged on a base 1a beside a Y-axis sliding module 1b in the base assembly 1, so that cable breakage caused by reciprocating motion of a slide block of the Y-axis sliding module is avoided. The rotary worktable can be understood from the partial structure, and can be used as a tray container for bearing a product to be detected, on one hand, the rotary worktable can be linearly displaced under the driving of the Y-axis sliding module and can be switched between a detection initial station and a feeding station; on the other hand, the product to be detected can rotate around the central line parallel to the Z axis under the driving of the DD motor, and the orientation of the product to be detected is adjusted, namely the position of the point to be detected of the product is positioned in the XY plane. In order to meet the requirement of omnibearing detection of the appearance of a product, the motion system of the equipment can avoid the increase of the space movable range of the detection part end and reduce the structural complexity and the control difficulty of the detection part end.
The requirement of detecting the omnibearing coverage from the appearance of a product is used for dividing the main body of the detection part into two aspects of side direction detection and top detection. As the name suggests, the side inspection component is a structural design for realizing the side inspection of the periphery of the product appearance. Specifically, as shown in fig. 2 and 3, the side inspection assembly 2 has a rear side plate 2a attached perpendicularly to the base 1a, and an X-axis sliding module 2b, a Z-axis sliding module 2c, a connecting seat 2d, and a Y1-axis module 2e and a Y2-axis module 2g respectively attached to the left and right sides of the connecting seat are integrally attached to the rear side plate 2a, wherein a first CCD camera and a first laser probe 2f are attached to a slider of the Y1-axis module 2e, and a second laser probe (not shown) is attached to a slider of the Y2-axis module.

Therefore, the connecting seat has high-precision positioning capability in the XZ plane, and the first CCD camera and the two laser probes move in the XZ plane along with the connecting seat. And the Y1 axis module and the Y2 axis module provide horizontal displacement positioning capability parallel to the Y axis, so that the distance fine adjustment of the CCD camera and the laser probe relative to a product to be detected according to the precision requirement of appearance detection is met.
Similar to the Y-axis sliding module, a second drag chain 21b for electric and pneumatic wiring is arranged at the top of the rear side plate 2a beside the X-axis sliding module 2b in the side inspection assembly; and a third drag chain 21c for electrical and pneumatic wiring is arranged beside the Z-axis sliding module 2c so as to avoid cable tear damage caused by the reciprocating motion of the sliders of the X-axis sliding module and the Z-axis sliding module.
Similarly, the top inspection component is a structural design for inspecting the top surface of the product appearance. Specifically, as shown in fig. 4, the top inspection module 3 has a supporting side plate 3a perpendicular to the base 1a and oppositely attached to both sides of the base with a space therebetween, and a top plate 3b bridged over the supporting side plate, the top plate 3b is integrally attached with an X1-axis sliding module 3c and a Z1-axis sliding module 3d, and a second CCD camera 3e and a third laser probe 3f are attached to a slide block of the Z1-axis sliding module. More specifically, the Z1 axis sliding module 3d is attached to the slider of the X1 axis sliding module 3c and is driven to linearly displace along the X1 axis, so that the CCD camera and the laser probe related to the top inspection module are controlled to be driven to displace along with the X1Z1 plane, the distance relative to the product to be tested is adjustable, and the testing precision is satisfied. Similarly, the X-axis sliding module 3c is also provided with a drag chain having a corresponding protection function, and the movement range of the Z1-axis sliding module is smaller, so that the drag chain is omitted.

Therefore, the Z-axis sliding module 2c can be guided to move with high precision, and the inclination caused by the self weight of the Z-axis sliding module and the inertia of the lower end suspension when the X-axis is translated is avoided.
In another embodiment, as shown in fig. 1, more than one replaceable vehicle 1e is attached to the surface of the rotary table 1 d. Therefore, the requirement that products with different shapes can be loaded by only one detection device and appearance detection with the same coverage degree is carried out is met, and the secondary development of the device function is facilitated while the application expandability of the device is obtained.
In another aspect, as understood from the control method and the implementation process of the detection device, the method mainly includes the following steps. And S1, resetting the DD motor and each shaft module and keeping the initial position before the equipment runs.

Controlling the DD motor to rotate by taking the value of theta as an input to adjust the orientation of the product; and taking the Y-axis coordinate value as an input to control the position of a slide block of the Y-axis sliding module to adjust the Y-axis position of the product. And the X-axis coordinate value is used as an input to control the slide block position of the X-axis sliding module to adjust the left and right positions of the first CCD camera, the second CCD camera and each laser probe, and the height Z value of the point to be measured is used as an input to control the slide block position of the Z-axis sliding module to adjust the height positions of the third CCD camera and each laser probe.
