[0002] Laser engraving is also known as laser marking. The laser engraving code is printed on the surface of the carton through a laser engraving marking machine to help companies track the flow of products during production, transportation and sales. When using a CCD visual detector to detect the laser-engraved 8S barcode on the carton, the carton will be squeezed and deformed during transportation and storage, causing the carton to have dents and uneven surfaces, which in turn causes the laser engraved code on the surface of the carton to be uneven, reducing the detection accuracy of the CCD visual detector. Summary of the invention

[0014] The present invention has the following advantages: the present invention controls the manipulator so that the connecting tube drives the suction cup to be tightly attached to the area around the laser engraved code on the carton, then controls the external air pump to suck air into the suction cup through the connecting tube, so that negative pressure is generated inside the suction cup, and then the suction cup is adsorbed on the surface of the carton where there is a recessed area, and then controls the manipulator so that the connecting tube drives the suction cup to move vertically upward perpendicular to the surface of the carton, and then the recessed area on the carton is pulled upward by the suction cup, and the recessed and uneven carton area around the position of the laser engraved code on the carton is flattened, so that the CCD detector is convenient for detecting the laser engraved code and the detection accuracy is improved.

[0025] Example 1

[0026] A barcode laser engraving detection machine based on intelligent recognition, such as Figure 1-Figure 6 As shown, a testing platform is included;

[0027] It also includes a manipulator 101, a connecting tube 102, a suction cup 103 and a sealing component; the testing platform is connected to the manipulator 101; the manipulator 101 is fixedly connected to the connecting tube 102; the connecting tube 102 is connected to the suction cup 103 made of rubber material; the connecting tube 102 is connected to a sealing component for sealing a partial area of ​​the suction cup 103.

[0028] The inspection platform includes a workbench 1, a conveyor belt 2, a material belt 3, a mounting frame 4, a mechanical claw 5 and a CCD detector 6; the workbench 1 is connected to the conveyor belt 2; the workbench 1 is connected to two material belts 3, and one material belt 3 is a good product channel, and the other material belt 3 is a defective product channel; the workbench 1 is fixedly connected to the mounting frame 4; the mounting frame 4 is fixedly connected to two mechanical claws 5; the mounting frame 4 is fixedly connected to a plurality of CCD detectors 6, and the CCD detectors 6 are distributed on the inner left side, inner right side and inner upper side of the mounting frame 4.

[0029] It also includes a fixing plate 104, a fixing ring 105 and an annular airbag 106; the connecting tube 102 is fixedly connected to two fixing plates 104; all the fixing plates 104 are commonly fixedly connected to the fixing ring 105; the fixing ring 105 is fixedly connected to the annular airbag 106, the annular airbag 106 is located outside the suction cup 103, and the annular airbag 106 is fixedly connected to the suction cup 103.

[0030] A rubber strip is provided on the lower side of the suction cup 103 so that the lower side of the suction cup 103 closely fits the wrinkled surface of the carton 7 , thereby improving the adsorption effect between the suction cup 103 and the surface of the carton 7 .

[0031] The sealing assembly includes an annular guide rail 107, an electric slider 108, an electric push rod 109, a round rod 1010 and a folding cloth 1011; the fixing ring 105 is bolted to the annular guide rail 107; the annular guide rail 107 is slidably connected to two electric sliders 108; each electric slider 108 is fixedly connected to an electric push rod 109; the telescopic ends of the two electric push rods 109 are commonly fixedly connected to the round rod 1010; the round rod 1010 is fixedly connected to the airtight folding cloth 1011, and the folding cloth 1011 is fixedly connected to the fixing ring 105.

[0032] The round rod 1010 is an inflatable rod.

[0033] When in use, connect the external air pump to the connecting pipe 102, connect the external air pump to the annular airbag 106, connect the external pump to the round rod 1010, and the external conveying device places the carton 7 to be inspected on the conveyor belt 2, and makes the bottom surface of the carton 7 contact with the conveyor belt 2, because the laser engraved code 71 will not exist on the bottom surface of the carton 7, and the laser engraved code 71 generally exists on the top surface or the four sides of the carton 7. Then, the conveyor belt 2 transports the carton 7 to the position of the mechanical claw 5 on the left side, and the mechanical claw 5 The carton 7 is placed on the workbench 1 and positioned in the middle of the CCD detectors 6. After any CCD detector 6 observes that the laser engraved code 71 on the carton 7 is concave and uneven, the manipulator 101 is controlled to make the connecting tube 102 drive the suction cup 103 to be closely attached to the area around the laser engraved code 71 on the carton 7. Then, the external air pump is controlled to suck air into the suction cup 103 through the connecting tube 102, so that negative pressure is generated inside the suction cup 103, thereby making the suction cup 103 adsorb on the concave area on the carton 7. Then, the manipulator 101 is controlled to make the connecting tube 102 drive the suction cup 103 to move vertically upward perpendicular to the surface of the carton 7, and then the concave area on the carton 7 is pulled upward by the suction cup 103, and the concave and uneven carton 7 area around the position of the laser engraved code 71 on the carton 7 is flattened, so that the CCD detector 6 can detect the laser engraved code 71 and improve the detection accuracy. After the concave and uneven carton 7 area around the position of the laser engraved code 71 is flattened, the external air pump makes the suction cup 103 is separated from the surface of the carton 7, and then the robot 101 is controlled to make the connecting tube 102 drive the suction cup 103 to move and leave the field of view of the CCD detector 6. Subsequently, the CCD detector 6 detects the laser engraved code 71 of the carton 7, compares it with the standard image, and determines whether there is a difference between the laser engraved code 71 on the carton 7 and the standard image. The robot claw 5 puts the carton 7 with qualified laser engraved code 71 into the material belt 3 of the good product channel, and puts the carton 7 with defective laser engraved code 71 into the material belt 3 of the defective channel.

[0034] When inspecting the laser engraved code 71 on the carton 7 of a smaller volume, the suction cup 103 cannot be completely attached to the carton 7 due to the fixed volume of the suction cup 103. The suction cup 103 appears to be suspended and loses its adsorption effect. At this time, the external air pump is controlled to inflate the annular airbag 106, and the inner side of the annular airbag 106 expands inward, and then the annular airbag 106 drives the lower side of the suction cup 103 to shrink inward, and the lower side of the suction cup 103 undergoes adaptive deformation, thereby making the lower side suction port of the suction cup 103 smaller, so that the suction port of the suction cup 103 can be aligned around the position of the laser engraved code 71 on the carton 7 of a smaller volume, and the uneven area of ​​the carton 7 is adsorbed and flattened to improve the adaptability of the suction cup 103.

[0035] When the laser engraved code 71 at the edge of the carton 7 is sunken, the lower side of the suction cup 103 cannot be completely attached to the surface of the carton 7, so that the lower side of the suction cup 103 is suspended. Even if the lower side of the suction cup 103 is contracted inward by the annular airbag 106, it cannot completely cover the surface of the carton 7. Figure 5 As shown, at this time, the electric push rod 109 is controlled to make the round rod 1010 pull the folding cloth 1011 to fit the side of the carton 7, and the folding cloth 1011 is unfolded, and then the folding cloth 1011 closes the suspended part of the lower side of the suction cup 103, so that a relatively closed space is formed between the lower side of the suction cup 103 and the surface of the carton 7, which is convenient for forming a negative pressure on the inner side of the suction cup 103 and adsorbing it on the surface of the carton 7, and pulling the area around the laser engraved code 71 on the carton 7 upward and flattening it, and by controlling the annular guide rail 107, the electric slider 108 drives the electric push rod 109, the round rod 1010, and the folding cloth 1011 to rotate, so that the round rod 1010 and the folding cloth 1011 are located on different sides of the carton 7.

[0036] When the laser engraved code 71 is located near the junction line 72 on the carton 7 and there is a depression around the junction line 72, due to the gap in the junction line 72, when the suction cup 103 is sucked, the outside air will enter the suction cup 103 from the gap in the junction line 72, so that the inner side of the suction cup 103 cannot form a negative pressure, thereby reducing the adsorption effect between the suction cup 103 and the surface of the carton 7. At this time, the external pump is controlled to suck air into the round rod 1010, so that the round rod 1010 of the inflatable rod shrinks and deflates. Then, the annular guide rail 107 is controlled to make the electric slider 108 drive the electric push rod 109, the round rod 1010, and the folded cloth 1011 to rotate, so that the round rod 1010 and the folded cloth 1011 are flush with the junction line 72. Then, the electric push rod 109 is controlled to make the round rod 1010 drive the folded cloth 1011 to be pulled to the lower side of the suction cup 103. Figure 6 As shown, then, the robot 101 is controlled to make the connecting tube 102 drive the suction cup 103 downward to fit the surface of the carton 7, and the suction cup 103 squeezes the deflated round rod 1010 onto the surface of the carton 7, so that the folded cloth 1011 covers the junction line 72, thereby forming a relatively closed space between the lower side of the suction cup 103 and the surface of the carton 7, so that the negative pressure inside the suction cup 103 is formed and adsorbed on the surface of the carton 7, and the area around the laser engraved code 71 on the carton 7 is pulled upward and flat.

[0037] Example 2

[0038] On the basis of Example 1, Figure 4 As shown, a filter cartridge 1012 is also included; the filter cartridge 1012 is connected to the connecting pipe 102 .

[0039] The connecting pipe 102 is detachably connected to the filter cartridge 1012, so that the filter cartridge 1012 can be easily cleaned and replaced.

[0040] It also includes a hot air pipe 1013 ; the suction cup 103 is fixedly connected with a plurality of hot air pipes 1013 .

[0041] When the external air pump is connected to the hot air pipe 1013, when there are a lot of dust and impurities on the surface of the carton 7, it will also affect the accuracy of the CCD detector 6 in detecting the laser engraved code 71. Therefore, after the suction cup 103 is attached to the surface area of ​​the carton 7 around the laser engraved code 71, when the external air pump sucks air to the suction cup 103 through the connecting tube 102, the dust on the surface of the carton 7 is sucked into the connecting tube 102, and the dust and impurities are filtered by the filter cartridge 1012 in the connecting tube 102, and then the dust and impurities on the surface of the carton 7 are cleaned, thereby improving the detection efficiency.

[0042] The carton 7 may become damp during storage, causing the area around the laser engraved code 71 on the surface of the carton 7 to become damp. At this time, after the suction cup 103 is attached to the damp area around the laser engraved code 71 on the surface of the carton 7, before the connecting tube 102 sucks air into the suction cup 103, hot air is input into the hot air pipe 1013 through an external air pump, so that the hot air dries the damp area around the laser engraved code 71, dries the surface of the carton 7, and improves the detection accuracy of the CCD detector 6.

[0043] Example 3

[0044] On the basis of Example 1, Figure 2 As shown, it also includes a tray 201, a drive motor 202 and an electric clamp 203; the workbench 1 is rotatably connected to the tray 201; the workbench 1 is bolted to the drive motor 202, and the output shaft of the drive motor 202 is fixedly connected to the tray 201; the tray 201 is fixedly connected to a plurality of electric clamps 203.

[0045] The receiving tray 201 is roughly designed to increase the friction between the receiving tray 201 and the carton 7 , thereby improving the fixing effect of the carton 7 on the receiving tray 201 .

[0046] In Example 1, the mechanical claw 5 places the carton 7 to be inspected on the supporting tray 201, and the electric clamper 203 clamps and fixes the carton 7 to prevent the carton 7 from shaking when it is sucked and pulled upward by the suction cup 103. In addition, since the laser engraved code 71 also exists on the four sides of the carton 7, when the CCD detector 6 observes that the laser engraved code 71 is located on the side of the carton 7, the supporting tray 201 drives the carton 7 to rotate ninety degrees by controlling the driving motor 202 until the side of the carton 7 with the laser engraved code 71 is located at a position that can be touched by the suction cup 103. Then, the robot arm 101 is controlled to make the connecting tube 102 drive the suction cup 103 to move to the side of the carton 7, and the concave area on the side of the carton 7 is sucked and flattened.

[0047] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the appended claims.
