The shearing picking device 4 and the vacuum grabbing mechanism 8 are respectively arranged on the two sides of the mounting base plate 2 along the length direction (i.e., the short side of the rectangular plate).

[0061] In the embodiment, the mounting base plate 2 is used as a fixed base plate of the positioning device 3, the cutting and picking device 4, the case opening cutter 6 and the grabbing device; the positioning device 3 is fixed on the first side of the mounting base plate 2, and is used for positioning a position of a to-be-cut packing tape on a carton and a position of a to-be-cut sealing port for sealing the carton, wherein the to-be-cut sealing port position of the carton is a sealing port position of the carton sealed by a transparent tape or a sealing tape; when the positioning device 3 is positioned at the to-be-cut packing tape position, the positioning device 3 sends a first signal with the to-be-cut packing tape position to a robot, so that the robot controls a mechanical arm to move the cutting and picking device 4 fixed on the second side of the mounting base plate 2 to the to-be-cut packing tape position according to the first signal, and controls a tip of a pneumatic cutter 42 of the cutting and picking device 4 to cut the packing tape; when the tip of the pneumatic cutter 42 cuts the packing tape on the carton, the robot controls a picking clamp 43 of the cutting and picking device 4 to pick the cut packing tape, wherein the second side is adjacent to the first side; when the positioning device 3 is positioned at the to-be-cut sealing port position, the positioning device 3 sends a second signal with the to-be-cut sealing port position to the robot, so that the robot controls the case opening cutter 6 fixed on the lower side of the mounting base plate 2 to move to the to-be-cut sealing port position according to the second signal, and controls the case opening cutter 6 to cut the transparent tape or the sealing tape at the to-be-cut sealing port position, so that the carton is opened; then, the grabbing device is used for grabbing the material from the opened carton; when the grabbing device grabs the material, the robot controls the grabbing device to move, so that the material is transported to a designated position.

[0063] In order to facilitate the assembly of the clamp, the end clamp further includes a flange connecting block 1, and the flange connecting block 1 and the case opening cutter 6 are respectively arranged on two sides in the thickness direction of the mounting base plate 2; specifically, the flange connecting block 1 is mounted on the top surface of the mounting base plate 2, and the case opening cutter 6 is mounted on the bottom surface of the mounting base plate 2; the flange connecting block 1 is used for connecting with a robot or a mechanical hand for controlling the movement of the end clamp.

[0064] It should be noted that the end clamp is connected with a six-axis robot or a mechanical hand through the flange connecting block 1, and the six-axis robot or the mechanical hand is used for controlling the rotation of the end clamp.

[0065] In the embodiment, the flange connecting block 1 is fixed to the upper central position of the mounting base plate 2, and the end clamp is flange-connected with the six-axis robot or mechanical hand through the flange connecting block; the end clamp and the flange connecting block 1 of the six-axis robot or mechanical hand are tightly combined through bolts, so as to form a detachable joint, which facilitates engineers to disassemble and replace the damaged end clamp, six-axis robot or mechanical hand. The six-axis robot is a machine that realizes various functions and automatically performs work by relying on its own power and control ability, and runs according to a pre-programmed program. The actual control of the six-axis robot is completed by a microcomputer. The first axis of the six-axis robot is the position of the linkage base plate, which is also the core position of bearing, and bears the weight of the entire robot and the large swing of the robot left and right horizontally. The second axis of the six-axis robot is an important axis for controlling the swing and extension of the robot front and back. The third axis of the six-axis robot is also an axis for controlling the swing of the robot front and back, but the swing range is much smaller than that of the second axis. The fourth axis of the six-axis robot is an axis for controlling the 180° rotation of the upper arm part, which is equivalent to the human forearm. The fifth axis of the six-axis robot is used to accurately position the end clamp to the first position or the second position through the fifth axis when the target position is determined, which is equivalent to the human wrist part. The sixth axis of the six-axis robot is used to move slightly through the sixth axis when the first position or the second position is positioned according to the fifth axis. The sixth axis is equivalent to a turntable that can rotate horizontally by 360°, which can more accurately position the first position or the second position. The software system of the six-axis robot can be reprogrammed according to the changes of the working environment and the changes of the workpiece. In the present application, the pre-programmed program can be modified to make the six-axis robot adapt to paper boxes of different sizes, thereby effectively improving the versatility of the device of the present application. The end clamp of the present application is controlled to move by the six-axis robot or mechanical hand, so that the paper box is opened, and the first material or the second material in the paper box is transported to the target position, thereby improving the automation degree of the production process.

The pickup clamp 43 is connected with the first cylinder 41, and the pickup clamp 43 is used to pick up the sheared packing belt.

[0067] The application positions the position of the to-be-cut packing belt on the carton and the position of the to-be-cut sealing opening of the sealed carton through the positioning device 3, moves the cutting and picking device 4 to the position of the to-be-cut packing belt through the mechanical arm, controls the first cylinder 41 to make the tip of the pneumatic scissors 42 cut the packing belt, controls the first cylinder 41 to make the picking clamp 43 pick the cut packing belt, then cuts the to-be-cut sealing opening through the opening cutter 6 to make the carton open, and then takes out the material from the opened carton through the grabbing device and transports the material to the target position.

[0068] In this way, the cutting of the packing belt on the carton, the cutting of the sealed carton and the transportation of the material in the carton are realized through the components of the end clamp, so that manual cutting of the packing belt, cutting of the sealed carton or transportation of the material in the carton is not needed, and the labor cost is greatly saved.

[0069] In some embodiments, the angle adjusting device 5 is arranged between the first cylinder 41 and the mounting plate 2, and is used to adjust the inclination angle of the first cylinder 41 and the mounting plate 2.

[0070] Of course, according to actual needs, the angle adjusting device 5 can be a swing device or a non-powered angle pad. For example, the first cylinder 41 is fixed to the mounting plate 2 through the angle pad, so that a preset angle of inclination is formed between the first cylinder 41 and the mounting plate 2, so that the pneumatic scissors 42 and the picking clamp 43 have enough rotation space, which is beneficial to the operation of cutting the packing belt and picking.

[0071] In some embodiments, the end clamp further comprises a cutter detection device 7; the cutter detection device 7 is connected to the bottom of the mounting plate 2, the opening cutter 6 is connected to the bottom of the cutter detection device 7, and the cutter detection device 7 is used to detect the opening cutter 6 to generate a replacement blade alarm when the head of the opening cutter 6 is detected to be incomplete.

For example, the robot or the six-axis mechanical arm controls the pneumatic scissors 42 of the end clamp to move to a to-be-cut packing belt position of the paper box packing belt and controls the pneumatic scissors 42 to cut the paper box packing belt at the to-be-cut packing belt position.

[0076] The above describes the end clamp and the unpacking device provided by the application, and the following describes a specific unpacking process of the unpacking device provided by the application.

[0078] In the embodiment, the paper box is conveyed by a power roller line, and a positioning cylinder in the power roller line is used for positioning the paper box. When the positioning cylinder determines that the paper box is located at the designated unpacking position, the positioning cylinder sends a first positioning signal to the robot or the six-axis mechanical arm, so that the robot or the six-axis mechanical arm determines that the paper box is located at the designated unpacking position according to the first positioning signal. When the robot or the six-axis mechanical arm determines that the paper box is located at the designated unpacking position, the six-axis robot controls the positioning device 3 of the end clamp to move to the designated unpacking position, so that the positioning device 3 positions the to-be-cut packing belt position and the to-be-cut sealing position on the paper box.

[0079] Step 2: The robot or the six-axis mechanical arm controls the pneumatic scissors 42 of the end clamp to move to the to-be-cut packing belt position and controls the pneumatic scissors 42 to cut the packing belt.
