[0040] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0041] Please refer to Figures 1 - 13 , the present invention provides a manipulator for carton packaging production equipment, including a six-axis manipulator body 100. A gripper is detachably installed at the working end of the six-axis manipulator body 100. The gripper includes a positioning frame 100 detachably fixed to the working end of the six-axis manipulator body 100, a left clamping arm 200 and a right clamping arm 300 symmetrically and slidably assembled on both sides of the positioning frame 100, and a first driving device 400 for driving the left clamping arm 200 and the right clamping arm 300 to move relatively or away from each other.

[0042] During use, the working end of the six-axis manipulator body 100 drives the gripper to move, and the left clamping arm 200 and the right clamping arm 300 of the gripper are used to clamp and transfer the stack of carton boards to the conveyor belt of the automatic packaging machine in sequence.

[0043] In the prior art, in order to improve the packaging efficiency, the cardboard boxes for packaging usually enter the automatic packaging machine in the form of a stack with a unit thickness, that is, after multiple stacks of cardboard boxes are stacked to a certain height, they are conveyed to the conveyor belt of the automatic packaging machine.

[0044] When the stacks of cardboard boxes are stacked in the Figure 1 shown manner, that is, when there are two stacks of cardboard boxes side by side in a column, when the prior art gripper places the left stack of cardboard boxes, since there is no stack of cardboard boxes on the right side, at this time, when placing the left stack of cardboard boxes, the left gripper arm 200 and the right gripper arm 300 are released after the bottom surface of the stack of cardboard boxes contacts the next layer of the stack of cardboard boxes; however, when placing the stack of cardboard boxes on the right side, due to the obstruction of the stack of cardboard boxes on the left side at this time, in order to reduce the gap between the two stacks of cardboard boxes, that is, the gap between the two stacks of cardboard boxes in the same column, in the prior art, when placing the stack of cardboard boxes on the right side, after the stack of cardboard boxes on the right side is flush with the top surface of the stack of cardboard boxes on the left side, the stack of cardboard boxes on the right side is directly released, and the stack of cardboard boxes on the right side freely falls to contact the next layer of the stack of cardboard boxes. During this process, the stack of cardboard boxes on the right side is likely to be skewed when colliding with the next layer of the stack of cardboard boxes, and there is also a certain safety hazard. The reason for the above placement is that in order to ensure the stability of clamping, the left gripper arm 200 and the right gripper arm 300 usually have a thickness, and due to the existence of the thickness of the left gripper arm 200 directly above, if the stack of cardboard boxes on the right side is released after contacting the next layer when placing the stack of cardboard boxes on the right side, at this time, there is a large gap between the two stacks of cardboard boxes in the same column.

[0045] To solve this problem, the left clamping arm 200 includes a left sliding part 210, a left clamping part 220, and a left driving part 230; the left sliding part 210 is slidably assembled on one side of the positioning frame 100, and the left clamping part 220 includes a plurality of thin plates 221 whose length sides are hinged to each other. One end of the thin plate 221 is provided with a connecting component 240 slidably assembled on the sliding part, and the left clamping part 220 can be driven by the left driving part 230 to switch between a first form and a second form. When the left clamping part 220 is in the first form, adjacent thin plates 221 are flipped along their hinge joints to form a wavy shape. When the left clamping part 220 is in the second form, adjacent thin plates 221 are flipped along their hinge joints to form a plate shape; the right clamping arm 300 includes a right sliding part 310, a right clamping part 320, and a right driving part 330; the right sliding part 310 is slidably assembled on the other side of the positioning frame 100, and the right clamping part 320 includes a positioning vertical plate 321 vertically welded to the bottom of the right sliding part 310, and a clamping vertical plate 322 slidably assembled horizontally on the side of the positioning vertical plate 321 close to the left clamping part 220. When the left clamping part 220 switches from the first form to the second form, the right driving part 330 is used to drive the clamping vertical plate 322 to move towards the left clamping part 220; when the left clamping part 220 switches from the first form to the first form, the right driving part 330 is used to drive the clamping vertical plate 322 to move away from the positioning vertical plate 321.

[0046] As Figure 13 shown, during the process of the gripper gripping the cardboard stack of the carton, the left clamping part 220 forms a first form under the drive of the left driving part 230, that is, a plurality of thin plates 221 form a wavy shape, and a plurality of left clamping surfaces for linear clamping are formed at the hinge joints of the plurality of thin plates 221 close to the right clamping part; the right clamping part 320, under the drive of the right driving part 330, makes the clamping vertical plate 322 closely adhere to the positioning vertical plate 321, and the positioning vertical plate 321 forms a right clamping surface. During clamping, the left clamping surface and the right clamping surface move relatively to complete the clamping of the cardboard stack of the carton. During this clamping process, the wavy shape formed by the plurality of thin plates 221 can significantly improve the bending resistance and prevent the left clamping part 220 from bending when the left clamping part 220 is stressed during clamping, affecting the clamping stability; when placing the cardboard stack on the right side of the carton, the cardboard stack on the right side of the carton can be moved into contact with the next layer and then the clamping is released. When releasing the clamping, the left driving part 230 and the right driving part 330 can be started synchronously. After the left driving part 230 is started, it drives the left clamping part 220 to switch from the first form to the second form, that is, a plurality of thin plates 221 switch from a wavy shape to a plate shape. After the right driving part 330 is started, it drives the clamping vertical plate 322 to move towards the left clamping part 220, so that the cardboard stack on the right side of the carton moves towards the cardboard stack on the left side. When the left clamping part 220 forms the second form, as Figure 8As shown, the left clamping arm 200 and the right clamping arm 300 are directly moved out. At this time, the gap between the left carton board stack and the right carton board stack is only slightly larger than the thickness of the thin plate 221. Under the premise of taking into account the safety during transportation, not only the gap between the two carton board stacks in the same row is reduced, but also the risk of the carton board stack tilting or tipping over due to the collision with the next layer of carton board stack when placing the right carton board stack is avoided.

[0047] like Figure 3 and Figure 13 As shown, in this specific embodiment, the two sides of the positioning frame 100 are symmetrically provided with slide grooves 110, and the left clamping arm 200 and the right clamping arm 300 are symmetrically and slidably assembled at the two ends between the pair of slide grooves 110. The first driving device 400 includes a first rotating shaft 410 and a sliding rod 420 respectively arranged in the pair of slide grooves 110 and passing through the left clamping arm 200 and the right clamping arm 300. The two ends of the first rotating shaft 410 are respectively provided with a first thread and a second thread with opposite threads, and the first thread and the second thread are respectively threadedly matched with the left clamping arm 200 and the right clamping arm 300. One end of the first rotating shaft 410 passes through the positioning frame 100 and is fixedly connected to the output end of the first motor 430 on the positioning frame 100. Based on the above design, the first motor 430 drives the first rotating shaft 410 to rotate. When the first driving shaft rotates, the first thread and the second thread on the first driving shaft respectively cooperate with the threads of the left clamping arm 200 and the right clamping arm 300, so that the left clamping arm 200 and the right clamping arm 300 can move toward or away from each other to complete the clamping and unclamping actions.

[0048] like Figure 4 and Figure 11 As shown, more specifically, the left sliding part 210 is slidably adapted between a pair of sliding grooves 110 and is located at one end of the first sliding groove 110, a through hole is provided at one end of the left sliding part 210 for the sliding rod 420 to pass through, and a first internal thread hole is provided at the other end of the left sliding part 210 for the screw to pass through and adapted to the first thread; the right sliding part 310 is slidably adapted between a pair of sliding grooves 110 and is located at the other end of the first sliding groove 110, a through hole is provided at one end of the right sliding part 310 for the sliding rod 420 to pass through, and a second internal thread hole is provided at the other end of the right sliding part 310 for the screw to pass through and adapted to the second thread.

[0049] Considering that when the left clamping portion 220 is transformed from the first state to the second state, a plurality of thin plates 221 will rub against the carton board stack, which may easily damage the edge of the carton board stack. Figure 5 and Figure 6As shown, in this specific embodiment, the left clamping portion 220 further includes a hinge shaft 222. Along the length direction of the hinge shaft 222, rolling wheels 223 are uniformly arranged, and the hinge shaft 222 between adjacent rolling wheels 223 forms a hinge section 224. Along the length side wall of the thin plate 221, hinge portions 221a are uniformly arranged, and the hinge portions 221a of adjacent thin plates 221 are mutually offset and hinged in the hinge section 224 of the hinge shaft 222. The radius of the rolling wheel 223 is greater than the thickness of the thin plate 221. Based on the above design, when the left clamping portion 220 is converted from the first form to the second form, the hinge shaft 222 can rotate to reduce the friction on the cardboard stack through the rolling wheels 223.

[0050] As Figure 5 and Figure 9As shown, in this specific embodiment, the connecting component 240 includes a fixing member 241 clamped at one end of the thin plate 221. Driving columns 242 are vertically arranged on the tops of the fixing members 241 at both ends. Swinging members 243 are vertically arranged on the tops of the other fixing members 241 except those at both ends. The swinging member 243 includes a first columnar portion 243a vertically fixed in the middle of the fixing member 241, a second columnar portion 243b vertically connected to the top end of the first columnar portion 243a, and a third columnar portion 243c vertically connected to the other end of the second columnar portion 243b away from the first columnar portion 243a. When the left clamping portion 220 is in the first form, the central axis of the third columnar portion 243c is located in the plane of the central axis of the hinge axis 222 on the side of the left clamping portion 220 away from the right clamping portion 320; a strip-shaped through groove 211 is vertically formed through the left sliding portion 210 along its length direction. The driving column 242 passes through the strip-shaped through groove 211 and is fixedly connected with a main driving block 244 slidably matched with the left sliding portion 210. The third columnar portion 243c of the swinging member 243 passes through the strip-shaped through groove 211 and is rotatably connected with a sub-driving block 245 slidably matched with the left sliding portion 210, and a torsion spring (not shown) is arranged between the third columnar portion 243c and the sub-driving block 245; the left driving portion 230 is used to drive the two main driving blocks 244 to move relatively or away from each other. Based on the above design, during use, when the left clamping portion 220 is transformed from the second form to the first form, the left driving portion 230 can drive the two main driving blocks 244 to move relatively, and the distance between the thin plates 221 at both ends is reduced. Under the action of the torsion spring, the third columnar portion 243c of the swinging member 243 rotates, so that the spaced hinge axes 222 move towards the right clamping arm, and several thin plates 221 deflect around their hinge axes 222 and gradually transform towards the first form. When the left clamping portion 220 is transformed from the first form to the second form, the left driving portion 230 can drive the two main driving blocks 244 to move relatively, and the distance between the thin plates 221 at both ends is increased. At this time, the torsion spring is twisted and compressed, and the third columnar portion 243c of the swinging member 243 rotates, so that the spaced hinge axes 222 move away from the right clamping arm, and several thin plates 221 deflect around their hinge axes 222 and gradually transform towards the second form.

[0051] As Figure 4 shown, in this specific embodiment, a limiting plate 500 is further arranged at the bottom of the left sliding portion 210. When the left clamping portion 220 is in the second form, the thin plate 221 is closely attached to the limiting plate 500.

[0052] As Figure 5As shown in the figure, in this specific embodiment, inclined surfaces 241a are symmetrically arranged on both sides of the two ends of the fixing member 241. When the left clamping portion 220 is in the first form, the inclined surfaces 241a of two adjacent fixing members 241 abut against each other. Based on the above design, through the abutment of the inclined surfaces 241a of the fixing member 241, the stability of the left clamping portion 220 in the first form is significantly improved. Further, the bending resistance of the left clamping portion 220 is improved.

[0053] As Figure 9 shown, specifically, the left driving portion 230 includes support side plates 231 symmetrically fixed on the top of the left sliding portion 210 at both ends of the strip-shaped through groove 211. A second driving shaft 232 passing through the two main driving blocks 244 is rotatably arranged between a pair of support side plates 231. The second driving shaft 232 is respectively provided with a third thread and a fourth thread with opposite threads. The third thread and the fourth thread are respectively in threaded cooperation with the corresponding main driving blocks 244. One end of the second driving shaft 232 is fixedly connected with a second motor 233. Based on the above design, when the second motor 233 drives the second driving shaft 232 to rotate, through the threaded cooperation relationship between the third thread and the fourth thread on the second driving shaft 232 and the corresponding main driving blocks 244, the two main driving blocks 244 can be driven to complete the actions of moving relatively or away from each other.

[0054] As Figure 11 shown, in this specific embodiment, a movable groove 321a is formed through the middle position of the positioning vertical plate 321. A movable block 322a slidably adapted to the movable groove 321a is arranged on the clamping vertical plate 322. The right driving portion 330 includes an electric telescopic rod. The electric telescopic rod is fixed on the side of the positioning vertical plate 321 away from the clamping vertical plate 322 through a fixed rib plate. The output end of the electric telescopic rod is fixedly connected with the movable block 322a. Based on the above design, the movement of the clamping vertical plate 322 is completed through the telescopic movement of the electric telescopic rod.

[0055] Further, a fall prevention plate 321b is vertically arranged at the bottom end of the side of the positioning vertical plate 321 close to the clamping vertical plate 322. Based on the above design, during the clamping process, the fall prevention plate 321b can be located below the clamped cardboard stack, and can support the cardboard stack when the cardboard stack accidentally slides downward, avoiding potential safety hazards caused by the cardboard stack falling.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
