[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a workpiece quality detection device, including a carrying component, a detection component, a control component and a suction component, the carrying component including a carrying plate 1 for placing multiple workpieces and a conveying device for driving the carrying plate 1 to move; the detection component includes multiple camera devices, and the multiple camera devices are used to simultaneously shoot multiple workpieces when the conveying device drives the carrying plate 1 to move to a preset detection position to generate a detection image; the control component is communicatively connected to the detection component, and is used to determine whether the quality of each of the multiple workpieces is qualified through the detection image; the suction component is communicatively connected to the control component, and is used to remove workpieces with unqualified quality under the control of the control component.

[0034] Specifically, in this embodiment, the workpiece is placed on the carrier plate 1, and the transport device drives the carrier plate 1 to the detection component and the suction component. The detection component and the suction component are both communicated with the control component. After the detection of each workpiece in the carrier plate 1 is completed, the detection component transmits the detection result to the control component, and the transport device transports the carrier plate 1 to the suction component. The control component controls the suction component to absorb defective workpieces in the detection results.

[0035] Specifically, in this embodiment, the conveying device includes a first conveying unit for conveying the carrier plate 1 to the detection position and a second conveying unit for conveying the carrier plate 1 to a preset suction position for suction by the suction component. The first conveying unit includes a positioning plate 2 for fixing the carrier plate 1, and a moving module 3 for driving the positioning plate 2 to move. The positioning plate 2 is a rectangular plate fixed on the moving module 3. A groove is provided on the positioning plate 2 for fixing the carrier plate 1 to prevent it from shaking during movement, resulting in unclear camera shooting. The moving module 3 includes a driving mechanism installed at the bottom of the positioning plate 2 and a servo motor connected to the driving mechanism. The driving mechanism can drive the positioning plate 2 to move horizontally or vertically, so that all four areas in the carrier plate 1 are photographed by the detection camera 6.

[0036] Specifically, in this embodiment, the second conveying unit includes a lifting mechanism 4 installed under the positioning plate 2 and a translation mechanism for driving the lifting mechanism 4 to move. A lifting hole 21 is opened on the positioning plate 2. When the moving module 3 drives the positioning plate 2 to enable the inspection camera 6 to complete the inspection of all workpieces in the carrier plate 1, the moving module 3 drives the positioning plate 2 back to the initial position, and the lifting mechanism 4 lifts the carrier plate 1 through the lifting hole 21. The translation mechanism 5 drives the lifting mechanism 4 to move the carrier plate 1 relative to the positioning plate 2, thereby transporting it to a preset suction position for the suction component to suck.

[0037] Specifically, in this embodiment, the detection device includes a detection camera 6 for photographing multiple workpieces to generate images. The detection camera 6 is communicatively connected to the control component. Multiple detection cameras 6 are installed to detect multiple areas in the carrier plate 1 at the same time.

[0038] Specifically, in this embodiment, four cameras are installed to inspect the workpieces in the carrier plate 1 under the conveyance of the conveying device. The four cameras divide the carrier plate 1 into four areas and inspect them simultaneously, thereby improving the inspection efficiency of the device.

[0039] Specifically, in this embodiment, the detection device also includes a detection light source 7 for providing fill light for the detection camera 6. The detection light source 7 is coaxially arranged with the detection camera 6. The detection light source 7 is a ring structure. The detection camera 6 photographs and detects the workpiece from the middle of the ring. The uniform illumination of coaxial light and the small reflection of the object are utilized to improve the accuracy and reproducibility of camera detection.

[0040] Specifically, in this embodiment, after the inspection camera 6 completes the inspection of the workpiece, the result can be temporarily stored in the inspection register in the control system. The inspection register can synchronously store the inspection result of the next tray of parts, so that when the suction component has not yet completed the suction of the previous tray of workpieces, the inspection component can start the inspection of the next tray of workpieces, thereby shortening the inspection time and improving production efficiency.

[0041] Specifically, in this embodiment, the suction component includes a material picking probe 9 for sucking the workpiece and an adjustment mechanism 8 for adjusting the position of the material picking probe 9. The adjustment mechanism 8 is specifically a high-precision four-axis robot. The material picking probe 9 is fixed at the end of the high-precision four-axis robot. The four-axis robot is communicated with the control component, and the material picking probe 9 is manipulated to reach the position of the defective workpiece, and the workpiece is sucked by vacuum suction.

[0042] Specifically, in this embodiment, the suction component also includes a storage box 10 fixedly mounted on the side of the adjustment mechanism 8 for placing the workpiece taken out by the material picking probe 9. After the material picking probe 9 sucks the defective workpiece, the four-axis robot drives the material picking probe 9 to move and places the workpiece in the storage box 10.

[0043] Specifically, in this embodiment, the workpiece quality inspection device further includes an interface component, which mainly includes an operating table 11, on which buttons are included, and the operating table 11 is communicatively connected with the control system.

[0044] The specific workflow of the above-mentioned quality inspection device may include the following operations:

[0045] Step 1: The staff places the carrier tray 1 filled with workpieces on the positioning plate 2 and presses the start button on the operating table 11 .

[0046] Step 2: The positioning plate 2 follows the driving module to move to the bottom of the detection camera 6 .

[0047] Step 3: The four inspection cameras 6 simultaneously photograph the workpieces in the carrier plate 1 within the corresponding field of view, and store the determination results in the corresponding inspection registers.

[0048] Step 4: After all the workpieces in the carrier plate 1 have been inspected, the driving module drives the positioning plate 2 to return to its initial position.

[0049] Step 5: The lifting mechanism 4 in the second conveying unit pushes out the carrier plate 1, and the translation mechanism 5 drives the lifting mechanism 4 to move relative to the positioning plate 2, and transports the carrier plate 1 to a preset suction position for suction by the suction component; at the same time, step 1 can start running again.

[0050] Step 6: The control system transmits the detection results to the high-precision four-axis robot. The robot transports the material-picking probe 9 to the defective workpiece according to the detection results. The material-picking probe 9 absorbs the defective workpiece and places it in the storage box 10.

[0051] Step 7: After the suction component is completed, the staff will take out the selected material tray and press the reset button.

[0052] The workpiece quality inspection device provided by the utility model transmits the inspection result to the control component through the communication connection between the inspection component and the control component, and the control component controls the suction component to accurately remove the defective products; a plurality of cameras are installed, and the products in the carrier plate 1 are divided into different areas for inspection at the same time, thereby improving the inspection efficiency, saving manpower, having a simple structure, strong versatility, improving the production efficiency, and being able to cope with the pick-and-place plate process of multiple parts and multiple combinations.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
