The material moving members 611 are used to receive the lids 300 with spoons with the cover openings facing upward; the first bracket 61a and / or the second bracket 61b are provided with a driving mechanism 63, and the driving mechanism 63 is used to drive the material moving member 611 to slide so that all the lids 300 with spoons on the first bracket 61a and all the lids 300 with spoons on the second bracket 61b are staggered in the sliding direction; the flipping mechanism 62 is connected to the first bracket 61a and the second bracket 61b, and the flipping mechanism 62 is used to drive the first bracket 61a and the second bracket 61b to flip so that the two rows of lids 300 with spoons that are staggered from each other are flipped and arranged in a straight line into one row. The above-mentioned turning device 6 realizes the turning of the lid with spoon 300 and also combines two rows of lids with spoon 300 arranged in parallel into one row, thereby effectively improving the production efficiency.

[0051] The flipping device 6 also includes a support frame 64, which includes a fixed support frame 641, two support arms 642 and a lifting drive mechanism 643. One end of the first support frame 61a and the second support frame 61b is connected to the flipping mechanism 62, and the flipping mechanism 62 is installed on one of the two support arms 642. The other ends of the first support frame 61a and the second support frame 61b are rotatably connected to the other of the two support arms 642. The two support arms 642 are slidably arranged on the fixed support frame 641. The lifting drive mechanism 643 is used to drive the two support arms 642 to slide along the fixed support frame 641 so that each material moving piece 611 on the first support frame 61a and the second support frame 61b approaches the spoon cover assembly device 5 to receive the spoon cover 300 and moves away from the spoon cover assembly device 5 after receiving the spoon cover 300.

[0052] Specifically, the material moving piece 611 is provided with a suction cup structure to absorb the spoon cover 300 with the cover opening facing upward on the spoon cover assembly device 5. The driving mechanism 63 includes a first driving mechanism 630a and a second driving mechanism 630b, which are respectively arranged on the first bracket 61a and the second bracket 61b; the first driving mechanism 630a and the second driving mechanism 630b respectively include a driver 631, a slide bar 632 and a plurality of push blocks 633, the slide bar 632 is arranged along the sliding direction and connected to the driver 631, the slide bar 632 is fixedly connected with a plurality of push blocks 633 along the sliding direction, the slide bar 632 is respectively slidably connected to a part of the material moving piece 611 on the first bracket 61a and a part of the material moving piece 611 on the second bracket 61b, the slide bar 632 drives the push blocks 633 to slide along the sliding direction, so that the push blocks 633 push the corresponding material moving piece 611 to slide.

[0053] In this embodiment, one of the two outermost material moving members 611 is fixedly connected to the slide bar 632, and push blocks 633 are correspondingly provided on both sides of each material moving member 611 between the two outermost material moving members 611; after the material moving member 611 absorbs the lid 300 with a spoon facing upward, the distance between each inner material moving member 611 and the corresponding push block 633 decreases in a first direction, and the first direction is the direction toward the material moving member 611 fixedly connected to the slide bar 632; when the driver 631 drives the slide bar 632 to slide in the first direction, the slide bar 632 first drives the corresponding material moving member 611 away from other material moving members 611, and the corresponding push block 633 then contacts and pushes the corresponding material moving member 611 in turn to expand the distance between all material moving members 611. After the distance is expanded, all material moving members 611 are symmetrically arranged on the first bracket 61a and the second bracket 61b, and the distance between adjacent material moving members 611 is equal.

[0054] The driving mechanism 63 also includes a dislocation driving mechanism 634. The first driving mechanism 630a is arranged on the first bracket 61a. One of the two outermost material moving parts 611 on the first bracket 61a is fixedly connected to the slide bar 632, and the other is far away from the slide bar 632 and fixedly connected to the first bracket 61a. The second driving mechanism 630b and the dislocation driving mechanism 634 are arranged on the second bracket 61b. The dislocation driving mechanism 634 includes a dislocation slider 6341, a dislocation driving cylinder 6342, and a connecting rod 6343 fixedly connected to the dislocation slider 6341. The dislocation slider 6341 is slidably connected to the second bracket 61b and connected to the output end of the dislocation driving cylinder 6342. The driver 631 in the second driving mechanism 630b is fixedly connected to the dislocation slider 6341. The dislocation slider 6341 is far away from the slide bar 632, and the connecting rod 6343 fixedly connected to the dislocation slider 6341 is far away from the slide bar 632. 11 is fixedly connected to the dislocation slide block 6341 through the connecting rod 6343. The dislocation slide block 631 drives the material moving parts 611 connected to the second driving mechanism 630b and the material moving parts 611 of the two outermost material moving parts 611 on the second bracket 61b, which are away from the slide bar 632, to slide along the sliding direction, so that the material moving parts 611 on the second bracket 61b are staggered with the material moving parts 611 on the first bracket 61a in the sliding direction. The flipping mechanism 62 drives the first bracket 61a and the second bracket 61b to rotate around their respective central axes to drive the material moving parts 611 and the spoon cover 300 with the cover opening facing upward on the material moving parts 611 to flip. After flipping, the spoon cover 300 faces downward and is received by the conveyor line 7.

[0055] See also Figure 1 and Fig.16 The automatic labeling detection and assembly system for spoon covers also includes a first actuator 80 and a first storage container 81. The first storage container 81 is arranged on one side of the conveyor line 7. The first actuator 80 is used to move the lid 300 with a spoon including the lid 100 and / or the spoon 200 that have not passed the inspection of the first visual inspection device 4 into the first storage container 81. The first visual inspection device 4 can detect the lid 100 whose interior and / or cover opening do not meet the standards and the spoon 200 whose back does not meet the standards. The first actuator 80 transfers the lid 300 with a spoon including the lid 100 and / or the spoon 200 that do not meet the standards to the first storage container 81 according to the inspection result of the first visual inspection device 4, so as to ensure the quality of the lid 300 with a spoon output by the conveyor line 7.

[0056] Specifically, there are multiple first actuators 80, and the first actuators 80 include air blowing tubes. The air blowing tubes of the multiple first actuators 80 are arranged at intervals along the conveyor line 7 to correspond to the multiple lids with spoons 300 on the conveyor line 7, respectively. The air outlets of the air blowing tubes face the first receiving container 81 to blow the lids with spoons 300 that do not meet the standards away from the conveyor line 7 and drop them into the first receiving container 81. Since the first actuators 80 correspond to the multiple lids with spoons 300 on the conveyor line 7 one by one, the first actuators 80 automatically kick out the unqualified lids with spoons 300 one by one, thereby improving production efficiency.

[0057] Specifically, whether the lid with scoop 300 meets the standard is determined based on the detection results of the first visual detection device 4 and the optical fiber sensor 5 .

[0058] Specifically, a first guide portion 811 is provided above the first storage container 81. The first guide portion can receive the non-standard lid with spoon 300 blown off the conveyor line 7 by the first actuator 80, and transfer the lid with spoon 300 to the first storage container 81 below it, so as to prevent the lid with spoon 300 from being blown away by the first actuator 80, which is conducive to the transfer of the non-standard lid with spoon 300 to the first storage container 81.

[0059] See also Figure 2 and Fig.16 The automatic labeling inspection and assembly system for the spoon cover further includes a second visual inspection device 9 disposed downstream of the conveyor line 7, and the second visual inspection device 9 is used to visually inspect the exterior of the spoon cover 300 with the cover opening facing downward on the conveyor line 7. Specifically, the label is attached to the outer top surface of the spoon cover 300. While the second visual inspection device 9 visually inspects the outer side surface and the outer top surface of the spoon cover 300, it also completes the inspection of the labeling condition of the top surface of the spoon cover 300, which is conducive to screening out the spoon cover 300 that does not meet the standards and improving the quality of the shipped products.

[0060] Specifically, the second visual inspection device 9 includes an upper visual device 91 and a plurality of side visual devices 92. The shooting end of the upper visual device 91 faces the conveying plane of the conveyor line 7 to shoot the outer top surface of the lid with a spoon 300. The plurality of side visual devices 92 are distributed on both sides of the conveyor line 7 to shoot the outer side surface of the lid with a spoon 300. Through the cooperation of the upper visual device 91 and the plurality of side visual devices 92, the outside of the lid with a spoon 300 can be shot at different angles, which is conducive to a comprehensive analysis of the outside of the lid with a spoon 300 and ensures the quality of the output lid with a spoon 300.

[0061] Specifically, the second visual inspection device 9 also includes a mounting frame installed on one side of the conveyor line 7, an upper visual device 91 is installed on the mounting frame, and the number of side visual devices 92 is four. The four side visual devices 92 are arranged in an X shape on both sides of the conveyor line 7. The upper visual device 91 is arranged above the center of the four side visual devices 92, so as to avoid the phenomenon that some structures are not photographed.

[0062] See also Figure 2 and Fig.16 The automatic labeling and inspection assembly system for spoon covers also includes a second actuator 82 and a second storage container (not shown). The second storage container is arranged on one side of the conveyor line 7. The second actuator 82 is used to move the spoon covers 300 that have not passed the inspection of the second visual inspection device 9 to the second storage container. The second actuator 82 automatically kicks out the spoon covers 300 according to the result of the second visual inspection device 9, which is conducive to quickly transferring the spoon covers 300 whose exteriors do not meet the standards among the multiple spoon covers 300 arranged in sequence on the conveyor line 7 to the second storage container, further ensuring the quality of the output spoon covers 300.

[0063] Specifically, the second actuator 82 includes an air blowing tube, which is used to blow the cup into the second storage container, so that the lid with spoon 300 that does not meet the standards can be quickly transferred to the second storage container, thereby improving efficiency.

[0064] Specifically, a second guide portion 83 is provided above the second storage container and is connected to one side of the conveyor line 7. The second guide portion 83 can receive the non-standard lid with spoon 300 blown away from the conveyor line 7 by the second actuator 82, and transfer the lid with spoon 300 to the second storage container below it, so as to prevent the lid with spoon 300 from being blown away by the second actuator 82, which is conducive to the accurate transfer of the non-standard lid with spoon 300 to the second storage container.

[0065] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
