[0046] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0047] like Figures 1 to 3 As shown, this embodiment provides a detection device 100 including a platform 10 , a carrier plate 40 , a first visual detection device 70 , and a second visual detection device 90 .

[0048] For the convenience of subsequent reading, the present application introduces a first direction Y, a second direction Z, and a third direction X to describe the embodiments of the present application. The first direction Y, the second direction Z, and the third direction X may be three non-parallel linear directions in space; further, the first direction Y, the second direction Z, and the third direction X may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0049] The carrier plate 40 is movably mounted on the machine 10 and is used to place the workpiece 50. The first visual inspection device 70 is movably mounted on the machine 10. The first visual inspection device 70 is disposed on one side of the carrier plate 40 along the first direction Y, and is used to emit a first inspection light 1 toward the workpiece 50. The first inspection light 1 is reflected by the workpiece 50 and then emitted to the first visual inspection device 70, so that the first visual inspection device 70 collects an image of the surface of the current workpiece 50 used to reflect the first inspection light 1.

[0050] The second visual inspection device 90 is movably mounted on the machine table 10. The second visual inspection device 90 is disposed on one side of the carrier plate 40 along the second direction Z, and is used to emit the second inspection light 3 toward the workpiece 50. The second inspection light 3 is reflected by the workpiece 50 and then emitted to the second visual inspection device 90, so that the second visual inspection device 90 collects an image of the surface of the current workpiece 50 used to reflect the second inspection light 3. The optical path direction of the second inspection light 3 intersects with the optical path direction of the first inspection light 1.

[0051] In this way, the detection device 100 of the present application, by providing the first visual detection device 70 and the second visual detection device 90, can simultaneously perform visual detection on at least two surfaces of the workpiece 50, thereby improving the detection efficiency of the product, and using the visual detection method, compared with visual detection, can reduce the error rate. In addition, the optical path direction of the second detection light 3 emitted by the second visual detection device 90 intersects with the optical path direction of the first detection light 1, so that when the first visual detection device 70 detects the outer surface of one side of the workpiece 50, the second visual detection device 90 detects the outer surface of the other side of the workpiece 50 or the inner surface of the workpiece 50 with the hole groove 51, thereby improving the practicality and detection efficiency of the detection device 100.

[0052] Please combine again Figure 1 and Figure 2 In one embodiment, the detection device 100 includes a control device 11, and the control device 11 is an industrial controller such as a PLC controller.

[0053] The control device 11 is connected to the first visual inspection device 70 and the second visual inspection device 90 by signals. On the one hand, the control device 11 controls the first visual inspection device 70 and the second visual inspection device 90 to work or stop working. On the other hand, the control device 11 obtains the images detected by the first visual inspection device 70 and the second visual inspection device 90, and compares the detected images with the pre-stored qualified images, so as to determine whether the current workpiece 50 is qualified.

[0054] For example, a qualified workpiece 50 is installed with rivets and rivets, and the workpiece 50 is provided with a through hole, and the through hole is in a state where no components are installed. The first visual inspection device 70 and the second visual inspection device 90 perform visual inspection on the workpiece 50 produced subsequently, and the control device 11 compares the detected image with the qualified image to determine whether the number of rivets in the detected image is the same as that in the qualified image, whether the number of rivets in the detected image is the same as that in the qualified image, and whether there are no rivets or rivets installed at each through hole. If all three of the above inspection standards are met, the workpiece 50 is qualified, and if any of the three inspection standards is not met, the workpiece 50 is unqualified.

[0055] Please combine again Figure 1 and Figure 2 In one embodiment, the machine 10 is square in shape, and the top surface of the machine 10 is flat. The machine 10 is a hollow structure.

A fan 28 is provided on one side of the machine 10 to dissipate heat from the control device 11 in the machine 10.

[0056] The inspection device 100 further includes a housing 20 , which covers the top of the platform 10 along the second direction Z, and the housing 20 and the platform 10 enclose a working chamber 21 . The carrier plate 40 , the first visual inspection device 70 , and the second visual inspection device 90 are all accommodated in the working chamber 21 .

[0057] Specifically, the housing 20 is a square structure with one end open and a hollow interior. The housing 20 is disposed around the top surface of the platform 10 , and the housing 20 and the platform 10 are detachably connected by bolting or the like.

[0058] Along the first direction Y, a loading and unloading opening 22 is opened on one side of the housing 20 . The loading and unloading opening 22 is connected to the working chamber 21 , so that the workpiece 50 can enter and exit the working chamber 21 through the loading and unloading opening 22 .

[0059] Furthermore, an operating button 24 and a signal light 23 are provided on the outer surface of the housing 20. The operating button 24 includes but is not limited to an emergency stop button, a start / stop button, etc., and the signal light 23 is used to display the current working state of the detection device 100. Both the operating button 24 and the signal light 23 are connected to the control device 11 by signals.

[0060] Furthermore, a safety grating 25 is installed on the housing 20 and is arranged around the inner wall of the access opening 22 to detect whether any foreign objects extend into the working chamber 21 when the detection device 100 is working, so as to avoid safety accidents.

[0061] Furthermore, a display screen 26 and a keyboard 27 are installed on the outer surface of the housing 20, and both the display screen 26 and the keyboard 27 are connected to the control device 11 by signals to achieve human-computer interaction.

[0062] Please combine again Figure 2 and Figure 3 In one embodiment, the detection device 100 includes a first moving device 30 , and the first moving device 30 includes a rotating component 32 and a first sliding component 31 .

[0063] The first sliding assembly 31 is mounted on the machine 10, and the first sliding assembly 31 is transmission-connected to the rotating assembly 32, and is used to drive the rotating assembly 32 to slide along the first direction Y. Specifically, the first sliding assembly 31 includes a first sliding driving member 311 and a first slide plate 312. Along the first direction Y, the first sliding driving member 311 is mounted on the top surface of the machine 10, and the first slide plate 312 is slidably mounted on the first sliding driving member 311. The first sliding driving member 311 is a cylinder slide or a screw slide, so as to drive the first slide plate 312 to slide back and forth along the first direction Y.

[0064] The rotating assembly 32 includes a rotating drive member 321 and a rotating plate 322. The rotating drive member 321 is a motor or a rotary cylinder, etc., and is installed on the first slide plate 312. The rotating drive member 321 is connected to the rotating plate 322 in a transmission manner, and is used to drive the rotating plate 322 to rotate around the second direction Z. The carrier plate 40 is installed on the top surface of the rotating plate 322 and is detachably connected to the rotating plate 322. The carrier plate 40 can be set to multiple to adapt to different workpieces 50. When different workpieces 50 need to be inspected, the corresponding carrier plate 40 can be replaced. The carrier plate 40 can be positioned with the rotating plate 322 by a positioning pin, and then connected to the rotating plate 322 by fasteners such as bolts.

[0065] In this way, the first sliding assembly 31 drives the workpiece 50 to move along the first direction Y, so that when the workpiece 50 needs to be inspected, the workpiece 50 is moved close to the first visual inspection device 70, and when the workpiece 50 is inspected, the workpiece 50 is moved close to the access opening 22 to facilitate the removal of the workpiece 50. The rotating assembly 32 drives the workpiece 50 to rotate around the second direction Z to adjust the outer surface of the workpiece 50 facing the first visual inspection device 70, thereby switching different outer surfaces for the first visual inspection device 70 to inspect.

[0066] Please combine again Figures 3 to 5 In one embodiment, the inspection device 100 further includes a clamping device 41 . The clamping device 41 is mounted on the carrier plate 40 and is used to clamp the workpiece 50 placed on the carrier plate 40 .

[0067] Specifically, the clamping device 41 includes a clamping drive 411, a clamping plate 412, and a baffle 413. The clamping drive 411 is a thrust cylinder or an electric push rod. The clamping plate 412 and the baffle 413 are spaced apart along the first direction Y or the third direction X. The clamping drive 411 is connected to the clamping plate 412 in a transmission manner, and is used to drive the clamping plate 412 to approach or move away from the baffle 413, so that the clamping plate 412 and the baffle 413 clamp the workpiece 50 between the two.

[0068] In one embodiment, the clamping devices 41 are provided in two groups, one group of clamping devices 41 is provided along the first direction Y to clamp the workpiece 50 along the first direction Y. The other group of clamping devices 41 is provided along the third direction X to clamp the workpiece 50 along the third direction X.

[0069] In another embodiment, for a workpiece 50 having a smaller thickness along the first direction Y, the clamping devices 41 may be provided in two or more groups, and each clamping device 41 is provided along the first direction Y to clamp the workpiece 50 along the first direction Y. Accordingly, for a workpiece 50 having a smaller length along the third direction X, the clamping devices 41 may be provided in two or more groups, and each clamping device 41 is provided along the third direction X to clamp the workpiece 50 along the third direction X.

[0070] Please combine again Figure 6 and Figure 7 , and see Figure 2 and Figure 3 In one embodiment, the detection device 100 includes a second moving device 60. The second moving device 60 includes a first lifting assembly 62 and a second sliding assembly 61. The first lifting assembly 62 is connected to the first visual detection device 70 for driving the first visual detection device 70 to rise and fall along the second direction Z. The second sliding assembly 61 is connected to the first lifting assembly 62 for driving the first lifting assembly 62 to slide along the third direction X.

[0071] Specifically, along the first direction Y, the second sliding assembly 61 is arranged at intervals on the rear side of the first moving device 30. The second sliding assembly 61 includes a second sliding driving member 611 and a second slide plate 612. Along the third direction X, the second sliding driving member 611 is installed on the top surface of the machine table 10, and the second slide plate 612 is slidably installed on the second sliding driving member 611. The second sliding driving member 611 is a cylinder slide or a screw slide, thereby driving the second slide plate 612 to slide back and forth along the third direction X.

[0072] The first lifting assembly 62 includes a first column 621, a first lifting drive 622, and a first lifting plate 623.

The first camera 71 is an industrial camera and adopts a wide-angle lens, which can capture images of a larger area to accommodate large-sized workpieces 50. The first light source 72 is a ring light source or a square light source, which emits a first detection light 1 toward the workpiece 50, and the first detection light 1 is reflected by the outer surface of the workpiece 50 and then emitted to the first camera 71.

[0074] In this way, the second sliding component 61 drives the first visual inspection device 70 to move in the third direction X, and the first lifting component 62 drives the first visual inspection device 70 to rise and fall in the second direction Z, thereby adjusting the position of the first visual inspection device 70 relative to the workpiece 50 to ensure that the first visual inspection device 70 detects the image of the entire outer surface of the workpiece 50 on the side facing the first visual inspection device 70.

[0075] Please combine again Figure 6 and Figure 8 , and see Figure 2 and Figure 3 In one embodiment, the detection device 100 includes a third moving device 80, and the third moving device 80 includes a second column 81, a connecting plate 82, a second lifting assembly 84 and a third sliding assembly 83. The second lifting assembly 84 is connected to the second visual detection device 90 for driving the second visual detection device 90 to rise and fall along the second direction Z. The third sliding assembly 83 is connected to the second lifting assembly 84 for driving the second lifting assembly 84 to slide along the third direction X.

[0076] Specifically, there are two second columns 81, and along the third direction X, the two second columns 81 are disposed on opposite sides of the first moving device 30. Along the second direction Z, the top surface of the second column 81 is higher than the workpiece 50 placed on the carrier plate 40, and the connecting plate 82 is disposed at intervals on the top of the workpiece 50 placed on the carrier plate 40.

[0077] The third sliding assembly 83 includes a third sliding driving member 831 and a third slide plate 832. The third sliding driving member 831 is installed on the front side of the connecting plate 82 along the first direction Y. The third sliding driving member 831 is a cylinder slide or a screw slide, and is arranged along the third direction X. The third slide plate 832 is slidably installed on the third sliding driving member 831, and the third slide plate 832 is driven by the third sliding driving member 831 to slide along the third direction X.

[0078] The second lifting assembly 84 includes a second lifting drive member 841 and a second lifting plate 842. The second lifting drive member 841 is installed on the front side of the third slide plate 832 along the first direction Y. The second lifting drive member 841 is arranged along the second direction Z and adopts a screw lifting mechanism or a lifting cylinder. The second lifting drive member 841 is connected to the second lifting plate 842 in a transmission manner to drive the second lifting plate 842 to rise and fall along the second direction Z.

[0079] Please combine again Figure 6 and Figure 8 , and see Figure 2 and Figure 3In one embodiment, the second visual inspection device 90 includes a second mounting plate 93, a second visual inspection module 91 and an adjustment mechanism 92. The second visual inspection module 91 is used to emit an initial light 2 toward the adjustment mechanism 92, and the optical path direction of the initial light 2 is parallel to the second direction Z. The adjustment mechanism 92 is used to adjust the optical path direction of the initial light 2 to form a second detection light 3, and the optical path direction of the second detection light 3 intersects with the optical path direction of the initial light 2, so that the first detection light 1 and the second detection light 3 are projected to the workpiece 50 from different directions, thereby collecting different images.

[0080] Specifically, the second visual inspection module 91 includes a second camera 911 and a second light source 912. Along the first direction Y, the second mounting plate 93 is fixed to the front side of the second lifting plate 842. Along the second direction Z, the second camera 911, the second light source 912, and the adjustment mechanism 92 are arranged in sequence, and the adjustment mechanism 92 is located on the side of the second camera 911 close to the workpiece 50. The second light source 912 is a ring light source or a square light source, etc., which is used to emit an initial light 2 to the adjustment mechanism 92. The initial light 2 changes the direction of the light path through the adjustment mechanism 92 to form a second detection light 3, and the second detection light 3 is projected onto the surface of the workpiece 50, and is reflected by the surface of the workpiece 50 and then projected to the second camera 911.

[0081] Furthermore, the adjustment mechanism 92 is a reflector, and the cross section of the reflector is a right triangle. The adjustment mechanism 92 has a reflective surface P, which is arranged toward the second visual detection module 91, and is used to reflect the initial light 2, and the normal direction of the reflective surface P is inclined to the first direction Y and the second direction Z. The reflective surface P is inclined downward from its top and toward the side away from the second moving device 60, and the angle between the normal direction of the reflective surface P and the first direction Y and the second direction Z is 45°. The initial light 2 is projected onto the reflective surface P along the second direction Z, and the reflective surface P reflects it to form a second detection light 3, and the optical path direction of the second detection light 3 is parallel to the first direction Y.

[0082] It is understandable that, when other embodiments are adopted, the adjustment mechanism 92 may also adopt a lens with a refractive function such as a prism, and change the optical path direction of the initial light 2 by multiple refractions of the initial light 2 in the prism. Alternatively, the adjustment mechanism 92 is movably connected to the second mounting plate 93, and the optical path direction of the second detection light 3 is adjusted by adjusting the posture of the reflection surface P.

[0083] It is worth noting that, for some workpieces 50, a hole groove 51 is provided on the top surface of the workpiece 50 along the second direction Z. The third sliding assembly 83 can drive the second visual inspection device 90 to move, so as to adjust the position of the second visual inspection device 90 relative to the workpiece 50 in the third direction X. The second lifting assembly 84 can drive the second visual inspection device 90 to move along the second direction Z, so that the second visual inspection device 90 enters the hole groove 51, and the second detection light 3 is projected onto the inner surface of the hole groove 51, thereby realizing the detection of the inner surface of the workpiece 50.

[0084] In the above, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions are all within the scope defined by the present application.
