[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0018] See also Figure 1 , Figure 2 As shown, the present embodiment discloses an all-in-one machine for visual inspection of flatness appearance, including a tray conveyor line 100 running along the X-axis, and a code scanning mechanism 200, a gold finger detection mechanism 300, a chip top detection mechanism 400, detection mechanisms on opposite sides of the long side and the bottom 500, a detection turntable 600, detection mechanisms on opposite sides of the short side 700, and a waste removal mechanism 800 are sequentially arranged on the same side of the tray conveyor line 100, wherein the tray conveyor line 100, the code scanning mechanism 200, the gold finger detection mechanism 300, the chip top detection mechanism 400, the detection mechanisms on opposite sides of the long side and the bottom 500, the detection turntable 600, the detection mechanisms on opposite sides of the short side 700, and the waste removal mechanism 800 are surrounded by the tray conveyor line 100 to form a "mouth" shape.
[0019] like Figure 6 As shown, the gold finger detection mechanism 300 includes a glass detection platform 310, a line scan camera 320 aimed at the glass detection platform 310, and a line scan X-axis linear module 330 for driving the line scan camera 320 to move. In this embodiment, the line scan camera 320 is located directly below the glass detection platform 310, and a first Y-axis vacuum manipulator 900a is provided above the feeding end 100a of the material tray conveyor line 100, the code scanning mechanism 200, and the glass detection platform 310 to connect the three.
[0020] like Figure 1 , Figure 2 As shown, the glass inspection platform 310 is connected to the chip top inspection mechanism 400 via a second Y-axis vacuum manipulator 900 b.
[0021] like Figure 1 , Figure 2 , Fig.10 As shown, the chip top detection mechanism 400, the two opposite sides of the long side and the bottom detection mechanism 500, and the detection turntable 600 are connected by a first X-axis vacuum manipulator 900c, and the detection turntable 600 and the detection mechanisms 700 on the two opposite sides of the short side are connected by a second X-axis vacuum manipulator 900d; a third Y-axis vacuum manipulator 900e is provided above the detection mechanisms 700 on the two opposite sides of the short side, the waste rejection mechanism 800, and the discharge end 100b of the tray conveyor line 100 to connect the three.
[0022] like Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the tray conveyor line 100 includes a belt group consisting of multiple pairs of conveyor belts 110, each pair of conveyor belts 110 includes two conveyor belts 110, and the feeding end and the receiving end of the belt group are respectively provided with a feeding bin 120a and a receiving bin 120b, and the feeding bin 120a and the receiving bin 120b both include: The warehouse body 121 is used to store the material tray 126. The material tray 126 is provided with a plurality of chip slots, each of which contains a chip. The warehouse body 121 is penetrated from top to bottom and from opposite sides. Two support members 122 are arranged on opposite sides of the bin body 121. Figure 3 , Figure 4 , Figure 5 As shown, the two support members 122 in this embodiment are located on both sides of the X-axis direction; The two-axis drive modules 123 of the two warehouse bodies respectively drive the two support members 122 to rise and fall and translate, that is, to move back and forth along the Z axis and the X axis, forcing the two support members 122 to move toward or in the opposite direction. When the two support members 122 move toward each other, the two support members 122 support the material tray 126 in the warehouse body 121. When the two support members 122 move in the opposite direction, the two support members 122 release the material tray 126 in the warehouse body 121. Lifting platform 124, such as Figure 5 As shown, the lifting platform 124 is located between the two conveying belts 110 below the warehouse body 121. The lifting platform 124 is driven and lifted by the warehouse body lifting cylinder 125. When the lifting platform 124 rises, it can extend into the warehouse body 121; when the lifting platform 124 descends, the lifting platform 124 is lower than the belt group.
[0023] When the upper bin 120a feeds the belt group of the tray conveyor line 100, a tray 126 is stacked in the bin body 121, and a plurality of chip products are placed on the tray 126. The two-axis drive modules 123 of the two bin bodies drive the two support members 122 to move toward each other, supporting the bottom tray 126 in the bin body 121. At this time, the bottom tray 126 is higher than the belt group; then, the bin body lifting cylinder 125 drives the lifting platform 124 to rise until it contacts the bottom tray 126 in the bin body 121 and no longer moves upward; the two-axis drive modules 123 of the two bin bodies drive the two support members 122 to move in the opposite direction. Move and release the material tray 126 at the bottom of the warehouse body 121; the warehouse body lifting cylinder 125 drives the lifting platform 124 to descend by the thickness of one material tray 126; then, the material tray 126 in the warehouse body 121 moves down as a whole by the thickness of one material tray 126; the two warehouse body two-axis driving modules 123 drive the two supporting members 122 to move toward each other again, and support the material tray 126 at the bottom of the warehouse body 121; at the same time, the warehouse body lifting cylinder 125 drives the lifting platform 124 to descend below the belt group, and the material tray 126 is received by the belt group, and the belt group drives the material tray 126 to move in the X-axis direction.
[0024] When the receiving bin 120b receives the material tray 126 detected on the belt group, the two bin body two-axis drive modules 123 drive the two support members 122 to move toward each other, supporting the lowermost material tray 126 in the bin body 121, and the bin body lifting cylinder 125 drives the lifting platform 124 to descend, and the lifting platform 124 is in a state lower than the belt group; when the detected material tray 126 is driven by the belt group to the top of the lifting platform 124, the bin body lifting cylinder 125 drives the lifting platform 124 to At the same time, the two-axis driving modules 123 of the two warehouse bodies drive the two supporting members 122 to move up the thickness of a material tray 126. Then, the lifting platform 124 drives the material tray 126 on the belt group to the bottom of the warehouse body 121. Then, the two supporting members 122 release the upper material tray 126 and descend to the two sides of the material tray 126 transferred to the warehouse body 121, and then move toward each other to clamp the material tray 126 transferred to the warehouse body 121, thereby completing the collection of the material tray 126.
[0025] like Figure 6 , Fig.10 , Fig.11 As shown, the first Y-axis vacuum manipulator 900a, the first X-axis vacuum manipulator 900c, the second X-axis vacuum manipulator 900d and the third Y-axis vacuum manipulator 900e all include a first manipulator two-axis drive module 910, a servo motor 920, and a first vacuum suction head 930. The servo motor 920 can move back and forth in the two-axis directions through the drive of the first manipulator two-axis drive module 910, and the first vacuum suction head 930 is driven to rotate by the servo motor 920.
[0026] like Fig. 9 As shown, the second Y-axis vacuum robot 900b includes a second robot two-axis driving module 940 and a second vacuum head 950. The second vacuum head 950 can move back and forth in the Y-axis and Z-axis directions through the drive of the second robot two-axis driving module 940.
[0027] In this embodiment, a position detection camera is arranged above the feeding end 100a of the tray conveyor line 100, and an identification hole is arranged on the chip. The position detection camera detects the position of the identification hole to identify whether the polarity direction of the chip is reversed. If reversed, the first vacuum suction head 930 of the first Y-axis vacuum manipulator 900a is used to absorb the chip. During the rising process, the servo motor 920 of the first Y-axis vacuum manipulator 900a drives the first vacuum suction head 930 to rotate 180°, and then transports it to the code scanning mechanism 200.
[0028] like Figure 6As shown, the code scanning mechanism 200 includes a code scanning gun 210, which is fixed to one side of the first vacuum suction head 930 of the first Y-axis vacuum manipulator 900a. The scanning port of the code scanning gun 210 is aligned with the two-dimensional code of the chip on the glass detection platform 310, so as to scan the two-dimensional code of the chip on the glass detection platform 310. The code scanning gun 210 is specifically arranged to be inclined to ensure that the code scanning port can be aligned with the chip on the glass detection platform 310. Since the two-dimensional code on the chip is formed by attaching a label or laser, if If the label is not attached or the laser is incomplete, the chip is an unqualified product. In order to replace manual inspection or inspection with other inspection equipment and thus improve the inspection efficiency, the present embodiment integrates a code scanning mechanism 200. The code scanning gun 210 does not require an additional drive module and is directly fixed on one side of the first vacuum suction head 930 of the first Y-axis vacuum manipulator 900a, thereby simplifying the equipment structure. After the first Y-axis vacuum manipulator 900a transfers the chip to the glass inspection platform 310, a code scanning inspection is performed first, and then a gold finger inspection is performed.
[0029] like Figure 6 As shown, a code scanning NG platform 220 is provided on one side of the glass inspection platform 310, and a plurality of code scanning NG slots 221 are provided on the code scanning NG platform 220. The code scanning NG platform 220 is located below the code scanning gun 210. The code scanning NG platform 220 can be moved between the code scanning gun 210 and the glass inspection platform 310 by the driving of the code scanning X-axis linear module 230, that is, it is located directly below the code scanning gun 210 and directly above the glass inspection platform 310.
[0030] The first vacuum suction head 930 of the first Y-axis vacuum manipulator 900a in this embodiment can transfer the defective chip to any position of the code scanning NG platform 220, and the code scanning X-axis linear module 230 is used to realize the movement of the code scanning NG platform 220 to any position on the X-axis, and the first manipulator two-axis driving module 910 of the first Y-axis vacuum manipulator 900a can move back and forth in the Y-axis and Z-axis directions. Therefore, through the cooperation of the code scanning X-axis linear module 230 and the first Y-axis vacuum manipulator 900a, arbitrary movement in the three-axis direction is realized. A plurality of evenly distributed code scanning NG slots 221 are provided on the code scanning NG platform 220, and each defective product can be placed in the code scanning NG slot 221, without the need for manual subsequent arrangement of the defective chips, thereby improving the efficiency of receiving defective chips.
[0031] In this embodiment, the barcode scanning X-axis linear module 230 is lower than the glass detection platform 310, and the barcode scanning NG platform 220 is higher than the glass detection platform 310. When the barcode scanning gun 210 detects that there is a problem with the two-dimensional code, the first vacuum suction head 930 of the first Y-axis vacuum manipulator 900a is first used to absorb the defective chip on the glass detection platform 310, and the barcode scanning NG platform 220 is then driven by the barcode scanning X-axis linear module 230 to move to the top of the glass detection platform 310, and is located below the defective chip. The first vacuum suction head 930 of the first Y-axis vacuum manipulator 900a transfers the defective chip to the barcode scanning NG platform 220. In this embodiment, the barcode scanning NG platform 220 can be transferred to the top of the glass detection platform 310, and the space above the glass detection platform 310 can be fully utilized, making the structure more compact and high in space utilization.
[0032] like Figure 8 , Fig. 9 As shown, the chip top detection mechanism 400 includes: Top visual inspection camera 410; The sliding transfer table 420 is located below the top visual inspection camera 410, and the second Y-axis vacuum manipulator 900b is connected to the glass inspection platform 310 and the sliding transfer table 420; The Y-axis linear module 430 is detected, and the Y-axis linear module 430 drives the sliding turntable 420 to move back and forth along the Y-axis between the glass detection platform 310 and the two opposite sides of the long side and the bottom detection mechanism 500.
[0033] The sliding transfer table 420 is used to receive the chip transferred by the first vacuum suction head 930 of the first Y-axis vacuum robot 900a, and then moved by the sliding transfer table 420 to the top visual inspection camera 410 for inspection, and then transferred to the opposite sides of the long side and the bottom inspection mechanism 500 after inspection.
[0034] like Fig.10 As shown, the detection mechanism 500 on the two opposite sides of the long side and the bottom includes: Two long side vision inspection cameras 510, the two long side vision inspection cameras 510 are arranged opposite to each other and distributed along the Y-axis direction; A bottom visual inspection camera 520 is located below and between the two long side visual inspection cameras 510; When the first X-axis vacuum robot 900c drives the chip to move between the two long-side visual inspection cameras 510 and above the bottom visual inspection camera 520, the two long-side visual inspection cameras 510 and the bottom visual inspection camera 520 perform visual inspections on the two side surfaces and the bottom surface of the chip one by one.
[0035] Two long side visual inspection cameras 510 and one bottom visual inspection camera 520 are used to realize flatness inspection of the two side surfaces and the bottom surface of the long side of the chip, and one by one inspection is adopted, that is, after one of the long side visual inspection cameras 510 completes the inspection, the second long side visual inspection camera 510 is then inspected, and finally the bottom visual inspection camera 520 is inspected, so that the flatness data obtained by the inspection will not be inaccurate due to the interference of other light sources, thereby ensuring the accuracy of chip inspection.
[0036] In addition, since the detection Y-axis linear module 430 drives the sliding turntable 420 to move in the Y-axis direction, and the first manipulator two-axis driving module 910 of the first X-axis vacuum manipulator 900c drives the first vacuum suction head 930 to move back and forth in the X-axis and Z-axis directions, after working together, the three-axis technical effect is achieved. Even if the chip position on the sliding turntable 420 is inaccurate, the purpose of precise grasping can be achieved by adjusting the position of the chip on the Y-axis and the position of the first vacuum suction head 930 on the X-axis and Z-axis.
[0037] like Fig.10 As shown, the short side opposite sides detection mechanism 700 includes two short side visual detection cameras 710, which are arranged opposite to each other and distributed along the Y axis direction. When the second X axis vacuum manipulator 900d drives the chip to move between the two short side visual detection cameras 710, the two short side visual detection cameras 710 perform visual detection on the two sides of the chip one by one. Similarly, detection one by one can ensure that the detection is not affected by other light sources, and can ensure the accuracy of the detection.
[0038] The reason why the two long-side visual inspection cameras 510 and the two short-side visual inspection cameras 710 are arranged in the Y-axis direction is that the device is in the shape of a "mouth" as a whole, and the space in the middle is relatively large, so this layout is more reasonable. The first X-axis vacuum manipulator 900c transfers the inspected chip to the inspection transfer table 600, and the first vacuum suction head 930 of the second X-axis vacuum manipulator 900d absorbs the chip and rotates it 90° by the servo motor 920, so that the two side surfaces of the short side of the chip are aligned with the two short-side visual inspection cameras 710 distributed on the Y-axis. After completing the visual inspection of the two side surfaces of the short side of the chip, the second X-axis vacuum manipulator 900d transfers it to the waste removal mechanism 800.
[0039] like Fig.11As shown, the short side opposite side detection mechanism 700 also includes a discharge turntable 720, which is located between the waste rejection mechanism 800 and the short side visual detection camera 710. The discharge turntable 720 is driven by the discharge Y-axis linear module 730 to move back and forth along the Y-axis, and the second X-axis vacuum manipulator 900d transfers the chip to the discharge turntable 720, and the third Y-axis vacuum manipulator 900e transfers the chip on the discharge turntable 720 to the waste rejection mechanism 800. Similarly, the discharge turntable 720 moves back and forth in the Y-axis direction, and the first vacuum suction head 930 of the second X-axis vacuum manipulator 900d moves in the X-axis and Z-axis directions, so as to achieve a three-axis effect. Even if the position of the discharge turntable 720 or the position of the chip grabbing is inaccurate, it can be adjusted, and finally the chip is accurately placed on the discharge turntable 720.
[0040] like Fig.11 As shown, the waste removal mechanism 800 in this embodiment includes a waste platform 810 and a waste X-axis linear module 820. The waste platform 810 is driven to the bottom of the third Y-axis vacuum manipulator 900e by the waste X-axis linear module 820; the waste platform 810 is provided with a gold finger NG groove, a chip top NG groove, a long side NG groove, a bottom NG groove, and a short side NG groove (not shown in the figure), which are respectively used to receive defective chips transferred by the third Y-axis vacuum manipulator 900e.
[0041] After the gold finger detection and six-side detection, the defective chips are uniformly collected on the waste platform 810. It is not necessary to equip each inspection station with an NG rejection structure, which saves space. Even if the third Y-axis vacuum manipulator 900e can only move on the Y-axis and Z-axis, the waste platform 810 with the X-axis movement can also achieve the effect of three axes, and the defective chips can be placed in the corresponding NG slot. The chips without defects are rotated 90° in the opposite direction by the third Y-axis vacuum manipulator 900e and placed in the material tray 126 above the belt group. After the material tray 126 is filled, it is transported to the receiving bin 120b by the belt group for collection.
[0042] In some embodiments, in order to improve the applicability of the device, the following settings may also be performed: The top visual inspection camera 410 can be adjusted in the X-axis and Z-axis directions through multiple sets of matching dovetail groove sliders and bolts; Both long edge visual inspection cameras 510 can be adjusted in the Y-axis direction through matching dovetail slides and bolts; The bottom visual inspection camera 520 can be adjusted in the X-axis and Z-axis directions through multiple sets of matching dovetail groove sliders and bolts; The inspection turntable 600 can be adjusted in the Z-axis direction through the matching dovetail slide and bolts; Both short-side visual inspection cameras 710 can be adjusted in the Y-axis direction through matching dovetail slides and bolts.
[0043] The working principle of this embodiment is: The loading bin 120a supplies a tray 126 filled with chips to the loading end of the tray conveyor line 100. When the tray 126 is transferred to the bottom of the first Y-axis vacuum manipulator 900a, the position detection camera first detects whether the polarity of the chips in the tray 126 is reversed. If it is reversed, the first Y-axis vacuum manipulator 900a grabs the chip, rotates it 180°, and transfers it to the glass inspection platform 310; if it is not reversed, the first Y-axis vacuum manipulator 900a directly transfers a chip to the glass inspection platform 310; then, the barcode scanner 210 scans the QR code of the chip on the glass inspection platform 310. If the code is NG, the NG platform is scanned. 220 moves to the top of the glass inspection platform 310, and the first Y-axis vacuum robot 900a transfers the chip with NG code scanning to the NG code scanning platform 220, and the NG code scanning platform 220 is reset; if there is no NG code scanning, the line scanning camera 320 detects the gold finger at the bottom of the chip; after the detection, the system records whether it is NG or not, and the second Y-axis vacuum robot 900b transfers it to the sliding transfer table 420, and the sliding transfer table 420 then transfers the chip to the bottom of the top visual inspection camera 410 for detection; after the top visual inspection camera 410 detects, the system records whether it is NG or not, and then the sliding transfer table 420 transfers it to the first X-axis vacuum robot 900c At the bottom, the first X-axis vacuum robot 900c absorbs and grabs the chip, and transfers it to the two opposite sides of the long side and the bottom detection mechanism 500, and detects the two sides and the bottom of the long side of the chip one by one. After the detection, the system records whether it is NG or not. The first X-axis vacuum robot 900c transfers the chip to the detection transfer table 600, and the second X-axis vacuum robot 900d transfers the chip on the detection transfer table 600 to the detection mechanisms 700 on the two opposite sides of the short side. Two short side visual detection cameras 710 detect the two sides of the short side one by one. After the detection, the system records whether it is NG or not. The second X-axis vacuum robot 900d transfers the chip to the discharge transfer table 720 , the third Y-axis vacuum manipulator 900e places the NG chips recorded by the system in the corresponding gold finger NG slot, chip top NG slot, long side NG slot, bottom NG slot, and short side NG slot in sequence, and directly loads them onto the tray; if there is no NG, the third Y-axis vacuum manipulator 900e directly transports them to the empty tray 126 at the receiving end of the tray conveyor line 100. At this time, the detection of one chip is completed. After all the chips in the tray 126 at the loading end are taken away for detection, the belt group of the tray conveyor line 100 transports the empty tray toward the receiving end. After the empty tray 126 at the receiving end is completely filled, the receiving bin 120b collects the full tray.
