The visual recognition device of this embodiment is a first visual camera 30. The first visual camera 30 is installed at the center of the working head 3. The first visual camera 30 is used to identify the position of the tape on the packaging material and the barcode on the packaging material. The glue-tearing device includes a clamping plate 31, a first clamping claw 32 and a first telescopic driver 33. The first telescopic driver 33 is connected to the first clamping claw 32 for driving the first clamping claw 32 to extend and retract.

After the folding action is completed, the third telescopic driver 36 on the working head 3 controls the negative pressure adsorption head 37 to extend and adsorb the packaging material, and lift the packaging material under the drive of the six-axis robot 2, and then the third clamping jaw 82 clamps the packaging material, and then the negative pressure adsorption head 37 releases the packaging material, and then the six-axis robot 2 moves the working head 3 to the other side of the packaging material, and then the negative pressure adsorption head 37 adsorbs the back of the packaging material to complete the reversing operation.

[0029] After the reversal is completed, the six-axis robot 2 drives the working head 3 to deliver the packaging material to the filling machine. The packaging material rotating device on the filling machine rotates and tightens the packaging material, and then the filling machine accurately docks it, cuts off the material head, and then sends it to the loading robot through a wireless signal, and the working head of the loading robot removes the material head and stores it.

[0030] like Figure 7 and Figure 8 As shown, a second visual camera 10 is also installed on the machine body 1. The second visual camera 10 is located on a side close to the filling machine. In this embodiment, the second visual camera 10 is installed close to the filling machine.

[0033] A linkage feeding method for a packaging material feeding system, using the above-mentioned feeding robot and filling machine, comprises the following steps: S1, when the filling machine detection belt needs to load packaging materials, a wireless signal is sent to the loading robot, and the loading robot moves to the vicinity of the filling machine driven by the walking mechanism; S2, the second visual recognition camera identifies and determines the parking error of the packaging material loading robot and cooperates with the walking mechanism to correct the error; S3, the robot arm moves the working head to the first visual recognition device facing the packaging material, the loading robot sends a wireless signal to the filling machine, and the packaging material rotating device controlled by the filling machine rotates the packaging material, and the first visual recognition device finds the adhesive tape bonding position of the packaging material; S4, after finding the adhesive tape bonding part of the packaging material, the feeding robot sends a wireless signal to the filling machine, and the filling machine controls the packaging material rotating device to stop rotating, so that the adhesive peeling device of the feeding robot grabs the end of the packaging material, and then the adhesive tape is torn off under the drive of the mechanical arm, and then the mechanical arm pulls the packaging material apart and places the packaging material part on the work surface; S5, the robot arm adjusts the position of the working head so that the first visual recognition device on the working head faces the packaging material on the working table, and then the reciprocating feeding device moves the packaging material on the working table. At this time, the first visual recognition device recognizes the QR code on the packaging material and locates the packaging material; S6, the cutting device cuts off the portion of the packaging material with the tape on it; S7, the robot arm adjusts the working head so that the paper folding device is located above the side of the paper folding baffle. At this time, the fourth telescopic driver extends out of the paper folding baffle, and then controls the paper folding device to press down, so that a crease is formed on the packaging material. The reciprocating feeding device drives the packaging material to move away from the filling machine, so that the crease of the packaging material passes under the pressure rod, so that the packaging material forms an acute angle at the crease. The fourth telescopic driver controls the pressure rod to press down, so that the packaging material is folded at the crease to further strengthen the crease. S8, the grasping device of the working head grasps the packaging material, and then the robot arm drives the working head to move, pulls the packaging material vertically, and then the packaging material reversing device fixes the packaging material, and then the grasping device releases the packaging material, and then the robot arm drives the working head to the back of the packaging material, and then the grasping device grasps the back of the packaging material; S9, the robot arm drives the working head to deliver the packaging material to the loading area of ​​the filling machine, and the filling machine completes precise splicing; S10, after the splicing is completed, the filling machine controls the material head cutting device to cut off the material head, and the filling machine sends a wireless signal to the feeding robot so that the feeding robot grabs the waste material head and stores it.
