[0002] Automation refers to the process in which machinery, equipment, systems or processes achieve the desired goals through automatic detection, information processing, analysis and judgment, manipulation and control in accordance with human requirements without or with little direct human participation. Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, services and family.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1: Figure 1-Figure 5 As shown, an automated packing robot described in an embodiment of the present invention includes a first conveying platform 1, a second conveying platform 3 is installed on one side of the first conveying platform 1, a robotic arm 2 is provided on the side of the second conveying platform 3, a first rectangular plate 21 is rotatably provided at the end of the robotic arm 2, a plurality of vacuum suction cups 211 are provided on the side of the first rectangular plate 21, a rolled foam sheet 4 is provided at the upper end of the second conveying platform 3, the end of the foam sheet 4 is clamped by a clamping assembly, the clamping assembly includes two fourth cylindrical wheels 422 slidably arranged at the lower end of the foam sheet 4, and two rotating first cylindrical wheels 24 are provided on one side of the first rectangular plate 21.

[0033] Specifically, when packing multiple fragile items, it is necessary to lay cushioning materials on the side walls of the box to protect the fragile items in the box during subsequent transportation. In the prior art, cushioning materials are generally laid on the side walls of the box before packing, and then the box is placed on the assembly line for automatic packing. During the packing process, the cushioning materials on the side walls may pile up together and have no protective effect. When using the present packing robot, the box is placed on the upper end of the second conveyor platform 3, and the items to be packed are placed on the upper end of the first conveyor platform 1. The rear driving robot arm 2 drives the first rectangular plate 21 to approach the upper end of the item to be boxed until the vacuum suction cup 211 contacts and adsorbs the item to be boxed, and then drives the robot arm 2 to move the item to be boxed to the upper end of the second conveyor 3, located at the lower end of the foam sheet 4, and pulls out the end of the rolled foam sheet 4 in advance and places it between the fourth cylindrical wheel 422, and then drives the fourth cylindrical wheel 422 to pull downward until the end of the foam sheet 4 is pulled between the two first cylindrical wheels 24, and then drives the first cylindrical wheel 24 to clamp the end of the foam sheet 4, and drives The first cylindrical wheel 24 is driven to rotate and drive the foam sheet 4 to move downward, and is located on the side of the item to be boxed. Then, the robot arm 2 is driven to move the item to be boxed and the clamped foam sheet 4 into the box, so that the foam sheet 4 is located on the side wall of the box. Then, the first cylindrical wheel 24 is driven to rotate so that the foam sheet 4 is completely separated from the first cylindrical wheel 24. By analogy, multiple items to be boxed are placed in the box in sequence. The vacuum suction cup 211 at the lower end of the first rectangular plate 21 is driven by the robot arm 2 to absorb the item to be boxed. Then, the fourth cylindrical wheel 422 is driven to drive the foam sheet 4 Pull it downward, and the first cylindrical wheel 24 will clamp the foam sheet 4 so that the foam sheet 4 is located on the side of the item to be packed. Then the cutting knife can be driven to cut the foam sheet 4, and then the robotic arm 2 is driven to drive the item to be packed and the foam sheet 4 clamped on the side to be placed in the box. The item to be packed will press the foam sheet 4 against the side of the box, which solves the problem of needing to lay the foam sheet 4 on the inner wall of the box in advance before packing, and the subsequent packing may cause the foam sheets 4 to pile up together. The position of the foam sheet 4 needs to be constantly adjusted during the automatic packing process, which is a more cumbersome problem.

[0034] like Figure 4 As shown, a first L-shaped block 41 is provided at both ends of the foam sheet 4, a third rectangular strip 42 is fixedly connected to the lower end of the first L-shaped block 41, a fourth rectangular strip 421 is slidingly provided on the side of the third rectangular strip 42, a fourth cylindrical wheel 422 is rotatably provided between the two fourth rectangular strips 421, a support frame 43 is fixedly connected to the lower end of the third rectangular strip 42, and the support frame 43 is fixedly connected to the side of the second conveying platform 3.

[0035] Specifically, when the end of the foam sheet 4 is pulled to the side of the item to be packed, the fourth rectangular bar 421 is driven to drive the fourth cylindrical wheel 422 to pull the end of the foam sheet 4 clamped in the middle downward until the end of the foam sheet 4 is pulled between the first cylindrical wheel 24, and then subsequent packing work is carried out.

[0036] like Figure 3 As shown, a second rectangular plate 22 is fixedly connected to one side of the first rectangular plate 21 , a first rectangular hole 221 is opened in the middle of the second rectangular plate 22 , first rectangular blocks 23 are fixedly connected to both sides of the second rectangular plate 22 , and a first cylindrical wheel 24 is rotatably set between the two first rectangular blocks 23 .

[0037] Specifically, after the fourth cylindrical wheel 422 pulls the end of the foam sheet 4 clamped in the middle downward to between the first cylindrical wheels 24, it then drives the two first cylindrical wheels 24 to slide in the middle of the two first rectangular blocks 23 to clamp the foam sheet 4 in the middle, and then drives the first cylindrical wheel 24 to rotate to drive the foam sheet 4 to move downward until the foam sheet 4 is completely located on the side of the item to be packed, and then the foam sheet 4 between the fourth cylindrical wheel 422 and the first cylindrical wheel 24 is cut off, and then packing can be carried out.

[0038] like Figure 3 、 Figure 5 As shown, second rectangular holes 231 are respectively opened on both sides of the middle part of the first rectangular block 23, and Z-shaped blocks 232 are respectively slidably arranged inside the second rectangular holes 231. The first cylindrical wheel 24 is respectively rotatably arranged between the two opposite Z-shaped blocks 232. The Z-shaped block 232 is fixed to one side of the second rectangular hole 231 through a spring 233. A bevel block 234 is respectively fixed to one side of the Z-shaped block 232, and a third rectangular block 428 is respectively fixed to the position of the bevel block 234 at the lower end of the fourth rectangular bar 421.

[0039] Specifically, by driving the fourth rectangular bar 421, the end of the foam sheet 4 clamped in the middle of the fourth cylindrical wheel 422 is driven to move downward, and at the same time, the third rectangular block 428 is driven to move downward until the third rectangular block 428 contacts the bevel block 234 and is driven along the bevel of the bevel block 234, sliding and driving the bevel block 234 to slide to both sides. At the same time, the bevel block 234 slides in the second rectangular hole 231 through the Z-shaped block 232 and squeezes the spring 233. The Z-shaped block 232 drives the first cylindrical wheels 24 on both sides to move to both sides at the same time, so that the ends of the foam sheet 4 can be located in the middle of the two first cylindrical wheels 24. Then, the fourth rectangular bar 421 drives the third rectangular block 428 to move upward, and the third rectangular block 428 moves away from the bevel block 234. At the same time, the spring 233 releases the elastic force, and drives the first cylindrical wheel 24 to slide toward the middle at the same time through the Z-shaped block 232, clamping the foam sheet 4 in the middle, and then drives the first cylindrical wheel 24 to rotate to move the foam sheet 4 to the side of the item to be packed.

[0040] like Figure 5 As shown, the two ends of the fourth cylindrical wheel 422 close to the side of the third rectangular bar 42 are respectively rotatably connected to the second connecting rod 423, the second connecting rod 423 is rotatably connected to the side of the fourth cylindrical wheel 422 corresponding to the cylindrical block 424, and the cylindrical blocks 424 are respectively slidably set on the side of the fourth rectangular bar 421, the second connecting rod 423 is rotatably connected to the third connecting rod 425 at one end away from the fourth cylindrical wheel 422, and the third connecting rod 425 is rotatably connected to the cylindrical wheel 426 at one end away from the second connecting rod 423 through damping rotation, and the cylindrical wheel 426 can rotate along one side of the third rectangular bar 42, and the two ends of the cylindrical wheel 426 are rotatably connected to the second rectangular blocks 427, and the second rectangular block 427 is slidably set on one side of the third rectangular bar 42.

[0041] Specifically, when the fourth rectangular strip 421 is driven to move downward, the cylindrical wheel 426 on one side is driven to rotate along one side of the third rectangular strip 42. Since the cylindrical wheel 426 is connected to the third connecting rod 425 through a damping connection, there is a large resistance. When the cylindrical wheel 426 rotates, the connection point between the third connecting rod 425 and the second connecting rod 423 is driven to rotate downward, and at the same time, the fourth cylindrical wheel 422 on one side is driven to approach the fourth cylindrical wheel 422 on the other side, clamping the end of the foam sheet 4 in the middle. The end of the movable foam sheet 4 moves downward, and after pulling the end of the foam sheet 4 to the middle of the first cylindrical wheel 24, the fourth rectangular strip 421 is driven to slide upward, driving the fourth cylindrical wheel 422 to slide upward, and at the same time driving the cylindrical rotating wheel 426 to rotate in the opposite direction along one side of the third rectangular strip 42, driving the rotation point between the third connecting rod 425 and the second connecting rod 423 to move upward, driving the fourth cylindrical wheel 422 on one side away from the fourth cylindrical wheel 422 on the other side, and will not clamp the foam sheet 4 in the middle when sliding upward.

[0042] like Figure 6 As shown, the upper ends of the first L-shaped blocks 41 are respectively rotatably provided with first connecting rods 411 through torsion springs, the rolled foam sheet 4 can be installed between the two first connecting rods 411, the lower ends of the rolled foam sheet 4 are rotatably provided with a second cylindrical wheel 412, the second cylindrical wheel 412 is rotatably provided between the two first L-shaped blocks 41, and two third cylindrical wheels 413 are rotatably provided between the two first L-shaped blocks 41 on the side away from the rolled foam sheet 4.

[0043] Specifically, when the thickness of the rolled foam sheet 4 becomes smaller, the first connecting rod 411 drives the rolled foam sheet 4 to rotate toward the second cylindrical wheel 412, so that the rolled foam sheet 4 is always in contact with the second cylindrical wheel 412 to prevent the rolled foam sheet 4 from becoming loose. The third cylindrical wheel 413 clamps the pulled foam sheet 4 to keep the foam sheet 4 in a straight state at all times.

[0044] like Figure 7As shown, a fifth rectangular bar 44 is fixedly connected to the opposite side of the lower end of the third rectangular bar 42 , a second L-shaped block 441 is slidably provided on the opposite side of the fifth rectangular bar 44 , and a steel wire 442 is fixed between the two second L-shaped blocks 441 .

[0045] Specifically, when the foam sheet 4 is pulled to the side of the item to be packed, the second L-shaped block 441 is driven to drive the steel wire 442 to slide toward the side close to the foam sheet 4, and the steel wire 442 is heated by powering on until the steel wire 442 contacts the foam sheet 4, and the foam sheet 4 is cut. Then, the item to be packed and the foam sheet 4 on the side can be placed in the box. By continuously cutting the foam sheet 4, the packing work can be carried out continuously.

[0046] like Figure 8 As shown, unpacking components are respectively provided at two diagonal positions of the second conveying platform 3, and the unpacking components include an L-shaped plate 7, the upper end of the L-shaped plate 7 is fixedly connected to the output end of the first electric telescopic rod 71, the end of the first electric telescopic rod 71 away from the L-shaped plate 7 is fixedly connected to the output end of the second electric telescopic rod 72, the end of the second electric telescopic rod 72 away from the first electric telescopic rod 71 is fixedly connected to the output end of the third electric telescopic rod 73, and the third electric telescopic rod 73 is fixedly connected to the side of the second conveying platform 3 through the connecting plate 74.

[0047] Specifically, since there are cover plates at the four corners of the upper end of the box, during the packing process, the two L-shaped plates 7 diagonally arranged on the second conveying platform 3 are driven to move upward by driving the third electric telescopic rod 73, and then the first electric telescopic rod 71 and the second electric telescopic rod 72 are driven to extend and retract so that the L-shaped plates 7 are located inside the upper end of the box, and then the third electric telescopic rod 73 is driven to drive the L-shaped plates 7 to move downward so that the L-shaped plates 7 are located at the diagonal positions on both sides of the cover plate on the upper end of the box, and then the first electric telescopic rod 71 and the second electric telescopic rod 72 are driven to extend and retract through the L-shaped plates 7 to drive the cover plates on the upper end of the box to rotate toward the outside of the box respectively. During the packing process, the cover plates on the upper end of the box are prevented from rotating inward, making the packing process smoother.

[0048] Example 2: Figure 9 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: two baffles 11 are slidably provided on the upper end of the first conveying platform 1, and a plurality of balls 111 are rotatably provided on opposite sides of the baffles 11.

[0049] Specifically, after placing the items to be boxed on the upper end of the first conveyor platform 1, the baffles 11 on both sides are driven to move toward the middle at the same time until the balls 111 contact both sides of the items to be boxed, so that the items to be boxed are located in the middle of the first conveyor platform 1, so that the first rectangular plate 21 drives the vacuum suction cup 211 to adsorb the middle of the upper end of the items to be boxed every time. When driving the first conveyor platform 1 to convey the items to be boxed, the balls 111 on both sides are driven to rotate to prevent friction on both sides of the items to be boxed.

[0050] like Figure 1 As shown, a fourth conveying platform 6 is provided on the side of the second conveying platform 3 away from the first conveying platform 1 , and a third conveying platform 5 is provided on the side of the second conveying platform 3 away from the robot arm 2 .

[0051] Specifically, the third conveyor platform 5 is used to convey several boxes to the upper end of the second conveyor platform 3, and then carry out the boxing work in sequence. After the boxing is completed, the boxes are conveyed to the upper end of the fourth conveyor platform 6, and then the subsequent box sealing work is carried out.

[0052] Working principle: After placing the items to be boxed on the upper end of the first conveyor platform 1, the baffles 11 on both sides are driven to move toward the middle at the same time until the balls 111 touch the two sides of the items to be boxed, so that the items to be boxed are located in the middle of the first conveyor platform 1, and the third conveyor platform 5 is driven to convey several boxes to the upper end of the second conveyor platform 3. The two L-shaped plates 7 set diagonally on the second conveyor platform 3 are driven to move upward by driving the third electric telescopic rod 73, and then the first electric telescopic rod 71 and the second electric telescopic rod 72 are driven to extend and retract so that the L-shaped plates 7 are located inside the upper end of the box, and then the third electric telescopic rod 73 is driven to extend and retract. The movable telescopic rod 73 drives the L-shaped plate 7 to move downward, so that the L-shaped plate 7 is located at the diagonal positions on both sides of the upper cover of the box. Then, the first electric telescopic rod 71 and the second electric telescopic rod 72 are driven to extend and retract through the L-shaped plate 7 to drive the upper cover of the box to rotate toward the outside of the box. During the packing process, the upper cover of the box is prevented from rotating inward. Then, the robot arm 2 is driven to drive the first rectangular plate 21 to move closer to the upper end of the object to be boxed until the vacuum suction cup 211 contacts and adsorbs the object to be boxed. Then, the robot arm 2 is driven to move the object to be boxed to the upper end of the second conveyor table 3.

[0053] The end of the foam sheet 4 is pulled out in advance and placed between the fourth cylindrical wheel 422. When the fourth rectangular strip 421 is driven to move downward, the cylindrical rotating wheel 426 on one side is driven to rotate along one side of the third rectangular strip 42. Since the cylindrical rotating wheel 426 and the third connecting rod 425 are connected by a damping connection, there is a large resistance. When the cylindrical rotating wheel 426 rotates, the connection point between the third connecting rod 425 and the second connecting rod 423 is driven to rotate downward, and at the same time, the fourth cylindrical wheel 422 on one side is driven to approach the fourth cylindrical wheel 422 on the other side, clamping the end of the foam sheet 4 in the middle. After that, the end of the foam sheet 4 is driven downward, and at the same time, the third rectangular block 428 is driven downward until the third rectangular block 428 contacts the bevel block 234 and is driven along the bevel of the bevel block 234, sliding and driving the bevel block 234 to slide to both sides. At the same time, the bevel block 234 slides in the second rectangular hole 231 through the Z-shaped block 232 and squeezes the spring 233. The Z-shaped block 232 drives the first cylindrical wheels 24 on both sides to move to both sides at the same time, so that the end of the foam sheet 4 can be located in the middle of the two first cylindrical wheels 24, and the end of the foam sheet 4 is pulled into the first cylindrical wheel 24. After that, the fourth rectangular strip 421 is driven to slide upward, driving the fourth cylindrical wheel 422 to slide upward, and at the same time driving the cylindrical rotating wheel 426 to rotate in the opposite direction along one side of the third rectangular strip 42, driving the rotation point between the third connecting rod 425 and the second connecting rod 423 to move upward, driving the fourth cylindrical wheel 422 on one side away from the fourth cylindrical wheel 422 on the other side. When sliding upward, it will not clamp the foam sheet 4 in the middle. When the fourth rectangular strip 421 drives the third rectangular block 428 to move upward, the third rectangular block 428 is away from the bevel block 234, and the spring 233 is released. The elastic force drives the first cylindrical wheel 24 to slide toward the middle at the same time through the Z-shaped block 232, clamping the foam sheet 4 in the middle. Then, the first cylindrical wheel 24 is driven to rotate to move the foam sheet 4 to the side of the item to be packed. Then, the second L-shaped block 441 is driven to drive the steel wire 442 to slide toward the side close to the foam sheet 4. The steel wire 442 is heated by electricity until it contacts the foam sheet 4, cutting the foam sheet 4. Then, the item to be packed and the foam sheets 4 on the sides can be placed in the box. By continuously cutting the foam sheets 4, the boxing work can be carried out continuously.

[0054] Then the robotic arm 2 is driven to carry the items to be packed and the foam sheets 4 clamped on the side and place them in the box. The items to be packed push the foam sheets 4 against the side of the box, which solves the problem that before packing, the foam sheets 4 need to be laid on the inner side walls of the box in advance, and the subsequent packing may cause the foam sheets 4 to pile up together. During the automatic packing process, the position of the foam sheets 4 needs to be constantly adjusted, which is a rather cumbersome problem. After the packing is completed, the box is conveyed to the upper end of the fourth conveyor platform 6, and then the subsequent sealing work is carried out.
