[0002] During the packaging process of display screens, it is usually necessary to put a layer of packaging bag on the outside. However, since the packaging bag is thin and soft, it is difficult for the robot to grab it directly. Therefore, the human-machine collaboration method is currently widely used to complete this task: first, the robot grabs the heavier display screen, and then the worker puts the plastic bag on the display screen; but this method is not only cumbersome to operate, but also has some problems. For example, the length of the plastic bag often exceeds the length of the display screen. When the display screen is lifted by the robot, it is difficult for the worker to completely put the plastic bag on; in addition, in the subsequent steps, when the robot puts down the display screen, the heavier display screen is easy to pierce the plastic bag due to falling, causing damage.

[0023] It also includes protrusions 205; each rotating roller 204 has six protrusions 205 in a circular array on the outside.

[0024] The bump 205 is made of rubber with a rough surface.

[0025] The clamping surfaces of the electric clamping jaws 105 are all provided with sponge pads 10501 .

[0026] The working principle of the above embodiment is as follows: by Figure 1 The viewing angle is the reference: the side where the number of the packaging bag 5 is located is the right side; the robot 1 is installed at the end of the conveyor belt of the transport display screen 4. First, as Figure 2 As shown: the manipulator 1 will control the electric guide rail 3, the fixed rod 101 and the suction cup 102 to absorb the display screen 4 placed flat on the conveyor belt according to the pre-programmed operation program. During this process, the electric push rod 103 will drive the first fixed block 104 and the electric clamping claw 105 to move upward, so that the electric clamping claw 105 is higher than the suction cup 102, so as to prevent the electric clamping claw 105 from affecting the suction effect of the suction cup 102 on the display screen 4; after the display screen 4 is sucked up by the suction cup 102, the manipulator 1 and the rotator 2 will drive the electric guide rail 3, the fixed rod 101 and the electric push rod 103 to move to Figure 1 In the state shown, the display screen 4 is kept vertical to the ground: the electric push rod 103 then drives the first fixed block 104 and the electric clamp 105 to move rightward, so that the display screen 4 is located in the middle of the electric clamp 105, and then the electric guide rail 3 controls the two sliders connected to the electric push rod 103 to move toward the display screen 4, and then the electric clamp 105 grabs the front and rear sides of the display screen 4. After the electric clamp 105 grabs the display screen 4, the suction cup 102 stops adsorbing the display screen 4; Then the worker first opens the packaging bag 5 and puts it under the display screen 4, and then folds the packaging bag 5 upwards and rolls it up. Figure 1-Figure 4 As shown: in the process of putting the packaging bag 5 on the lower part of the display screen 4, the worker first pulls up the clamping block 108, at which time the second tension spring 110 is compressed and stretched, and the clamping block 108 moves upward, and then the worker puts the upper side of the packaging bag 5 between the corresponding clamping block 108 and the sliding block 107, and then the worker releases the clamping block 108, at which time the second tension spring 110 contracts and resets, thereby driving the clamping block 108 to move downward to clamp the upper side of the packaging bag 5; then the worker rolls up the packaging bag 5 so that the bottom of the packaging bag 5 fits the bottom of the display screen 4 to avoid a large gap between the display screen 4 and the bottom of the packaging bag 5, which causes the heavier display screen 4 to easily pierce the packaging bag 5 due to falling when the robot 1 puts down the display screen 4, causing damage to the display screen 4; and as shown Figure 3As shown, at this time, the folded portion generated after the packaging bag 5 is rolled up is located between the sliding block 107 and the corresponding second fixed block 203, and then the worker controls the electric clamp 105 to move downward through the control system in the manipulator 1. During this process, the electric clamp 105 will drive the display screen 4 and the first extrusion block 106 to move downward at the same time. At this time, the wedge surface 10601 will squeeze the wedge block 10701, and then squeeze the sliding block 107 toward the corresponding rotating roller 204. At this time, the packaging bag 5 is pulled to both sides by the sliding block 107, thereby opening the packaging bag 5, so as to facilitate the subsequent placement of the display screen 4 into the packaging bag 5; and then rotate The roller 204 will contact the packaging bag 5 on the outside of the sliding block 107, and then cooperate with the sliding block 107 to clamp the front and rear sides of the packaging bag 5, and at the same time limit the contraction part of the packaging bag 5 to the upper side of the rotating roller 204 to prevent the packaging bag 5 from falling downward. It should be noted that workers are required to assist in this process to prevent the packaging bag 5 from falling. After the rotating roller 204 cooperates with the sliding block 107 to clamp the front and rear sides of the packaging bag 5, no worker operation is required, and then the electric clamp 105 will continue to drive the display screen 4 to move downward, and then the packaging bag 5 will be squeezed downward by the downward movement of the display screen 4. At this time, it is based on the view from the front to the back. Figure 4 and Figure 5As shown: the downward movement of the packaging bag 5 will generate a large friction force on the rotating roller 204, thereby driving the rotating roller 204 to rotate clockwise; at this time, the limit block 207 will follow the rotating roller 204 to rotate clockwise, thereby squeezing the torsion spring 206, and the torsion spring 206 will shrink under pressure and generate a reset force for counterclockwise rotation, driving the rotating roller 204 to generate a reset force for counterclockwise rotation, thereby limiting the downward movement of the packaging bag 5. After the limit block 207 drives the torsion spring 206 to rotate a certain number of times, the torsion spring 206 will be compressed and contracted to the extreme. At this time, the limit block 207 will pass over the torsion spring 206, and then the torsion spring 206 is no longer compressed and quickly The limit block 207 is repositioned to prevent the torsion spring 206 from driving the rotating roller 204 to generate a large reset force after being continuously compressed, thereby causing a large pull on the packaging bag 5 and causing damage to the packaging bag 5. In the process of the torsion spring 206 rotating counterclockwise to reset, the torsion spring 206 will contact the limit block 207 after rotating one circle. Therefore, when the folded part of the upper side of the packaging bag 5 is pulled downward by the display screen 4, the lower part of the packaging bag 5 will fall downward, and the bottom of the packaging bag 5 will not contact the display screen 4. Then, the torsion spring 206 will drive the limit block 207 to rotate in the process of continuing to rotate counterclockwise to reset, thereby driving the rotating roller 204 The excess part of the packaging bag 5 is pulled upward by rotating the roller 204, so that the bottom of the packaging bag 5 contacts the display screen 4 again. Then, the downward movement of the packaging bag 5 is restricted by rotating the roller 204 during the process of the display screen 4 pressing the packaging bag 5 downward, so that the display screen 4 can not only smoothly press the packaging bag 5 downward, that is, put it into the packaging bag 5, but also make the display screen 4 always fit with the bottom of the packaging bag 5, avoiding a large gap between the display screen 4 and the bottom of the packaging bag 5, resulting in the heavy display screen 4 easily piercing the packaging bag 5 due to falling when the robot 1 puts down the display screen 4, causing damage to the display screen 4. When the display screen 4 is completely put into the packaging bag 5, the electric The clamping jaws 105 are released; the display screen 4 falls downward, but at this time the display screen 4 is in contact with the bottom of the packaging bag 5, and the packaging bag 5 is clamped by the clamping block 108, so the display screen 4 will not fall downward, and then the robot 1 will put the display screen 4 and the packaging bag 5 into the packaging box together. It should be noted here that the packaging box is already on the lower side of the display screen 4, so when the display screen 4 is squeezed downward and inserted into the packaging bag 5, the display screen 4 and the packaging bag 5 also enter the packaging box together; after the display screen 4 is placed in the packaging box, the worker controls the electric clamping jaws 105 to move upward and reset, and then pulls up the clamping block 108 to remove the upper side of the packaging bag 5, and then the robot 1 continues to carry out the next packaging.

[0027] According to the above working principle, we know that the present invention has the following effects: By reducing manual intervention in the packaging process, simplifying operations, improving production efficiency and consistency, and reducing the workload of workers and labor costs, the roller 204 is rotated to limit the downward movement of the packaging bag 5 during the process of the display screen 4 squeezing the packaging bag 5 downward, so that the display screen 4 can not only smoothly squeeze the packaging bag 5 downward, that is, put it into the packaging bag 5, but also make the display screen 4 always fit with the bottom of the packaging bag 5, avoiding a large gap between the display screen 4 and the bottom of the packaging bag 5, resulting in the heavy display screen 4 easily piercing the packaging bag 5 due to falling when the robot arm 1 puts down the display screen 4, causing damage to the display screen 4.

[0028] On the basis of the above technical effects, the present invention also has the following advantages: A plurality of protrusions 205 are arranged on the outer side of the rotating roller 204, and the protrusions 205 are made of rubber material with a rough surface, which greatly increases the friction between the rotating roller 204 and the surface of the packaging bag 5, and improves the pulling and limiting effect of the rotating roller 204 on the packaging bag 5; The clamping surfaces of the electric clamping jaws 105 are all provided with sponge pads 10501 to prevent the electric clamping jaws 105 from damaging the display screen 4 .

[0029] Example 2 On the basis of Example 1, Figure 6 and Figure 7 As shown, a fixing groove 10703 is provided on the upper side of each sliding block 107 ; a hollow partition is provided in the packaging bag 5 , and a connecting end 5001 is provided on the upper side of the packaging bag 5 , and the connecting end 5001 is communicated with the hollow partition in the packaging bag 5 .

[0030] A second extrusion block 10801 is provided on the lower side of each clamping block 108 .

[0031] It also includes a connector 201, an inflation tube 202 and a connecting tube 208; each first fixed block 104 is fixedly connected to a connector 201, and an air pump is arranged inside the connector 201; two inflation tubes 202 are connected between the lower side of each connector 201 and the sliding block 107, and the air pump inside the connector 201 is connected to the corresponding connecting groove 10704 through the inflation tube 202; each sliding block 107 is provided with a connecting groove 10704; a plurality of connecting tubes 208 are fixedly connected inside the sliding block 107; the connecting groove 10704 is connected to the corresponding connecting end 5001 through the connecting tube 208.

[0032] The working principle of the above embodiment is as follows: When the packaging bag 5 is clamped by the clamping block 108 as described in Example 1: Figure 6 and Figure 7As shown: when the worker puts the upper side of the packaging bag 5 between the clamping block 108 and the sliding block 107, the worker can pull up the clamping block 108 and then grab the connecting end 5001, and then directly put the connecting end 5001 into the fixed groove 10703, and then the worker releases the clamping block 108 to quickly clamp the upper side of the packaging bag 5, which is convenient for the worker to operate. At this time, the connecting end 5001 is squeezed by the clamping block 108, and the connecting pipe 208 is inserted into the connecting end 5001, and the connecting end 5001 is connected with the connecting groove 10704. When the display screen 4 is completely placed in the packaging bag 5, the air pump in the connector 201 is started, and the connecting groove 10704 is inflated through the inflation pipe 202, and then the gas enters the hollow partition of the packaging bag 5 through the connecting groove 10704 and the connecting pipe 208, and then the hollow partition of the packaging bag 5 expands and hardens, thereby forming an airbag protection layer on the outside of the display screen 4, which greatly improves the protection effect of the packaging bag 5 on the display screen 4.

[0033] According to the above working principle, we know that the present invention has the following effects: After packaging is completed, the air pump in the connector 201 is used to inflate the hollow partition of the packaging bag 5, causing the hollow partition of the packaging bag 5 to expand and harden, thereby forming an airbag protection layer on the outside of the display screen 4, greatly improving the protection effect of the packaging bag 5 on the display screen 4.

[0034] On the basis of the above technical effects, the present invention also has the following advantages: After the clamping block 108 is pressed downward to reset, the second extrusion block 10801 will enter the fixing groove 10703, which greatly improves the clamping and fixing effect of the clamping block 108.
