Description

Generally, the assembly is completed by the robot on the production line. That is, the robot grabs the separator paper and puts it on the corresponding workbench for loading.

[0003] The shortcomings of the existing separator paper loading mechanism are: the existing separator paper loading mechanism relies on a suction cup assembly to suck up the separator paper, and then transfers the position to complete the loading. When the suction cup assembly sucks up the separator paper, it relies on up and down reciprocating extension and contraction to shake, so as to make the material body adhered to the bottom of the sucked up separator paper fall down, ensuring that only one piece of separator paper is loaded each time. However, relying solely on up and down reciprocating shaking cannot effectively ensure that the adhered separator paper falls down, and the processing effect is not good enough.

[0012] As a further solution of the present invention: the auxiliary suction and pulling mechanism includes an air cylinder, which is connected to the bottom side of the one-way movable block, and the end of the air cylinder away from the one-way movable block is connected to the air outlet end of the air pump through a hose, and a first air leakage hole is provided on the air cylinder, and a piston column is slidably inserted into the other end of the air cylinder, and the piston column is connected to the end of the second linkage rope, and an auxiliary suction cup assembly is provided at the end of the piston column.

[0016] Beneficial effects of the present invention:

[0017] 1. When the vacuum suction cup assembly of the present invention sucks the separator paper and lifts it up, it passes through the position of the one-way movable stopper, which pushes the one-way movable stopper upward. During this process, the one-way movable stopper starts the air pump. At the same time, the air cylinder provided on the one-way movable stopper pushes the piston upward due to inflation, so that the rubber suction cup is adsorbed on the bottom of the separator paper body. When the rubber suction cup rises and adsorbs on the bottom of the separator paper body, the air pump is shut down, so that the piston falls back under the action of gravity, thereby pulling the bottom of the separator paper body through the rubber suction cup. At this time, if there is another piece of material adhered to the bottom of the separator paper body, it will be separated as the rubber suction cup pulls it, so that one piece of material can be loaded each time.

[0018] 2. After the partition paper material body is raised, the one-way movable stoppers of the present invention are distributed on both sides of the bottom of the partition paper material body to perform position limiting and blocking to prevent it from falling during the loading and transfer process. In addition, the one-way movable stoppers can automatically shift their positions when the partition paper material body is dropped to avoid obstruction, thereby ensuring that the partition paper loading is carried out effectively.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] like Figures 1-6As shown, a separator paper loading mechanism is applied to a liquid crystal screen glass packaging production line, comprising a main linear movable guide rail 1, which is used to be installed on a separator paper material bin 24, which can cooperate with a material conveying line, and one end of the main linear movable guide rail 1 is a loading assembly table, and a sensor is provided in the separator paper material bin 24. When the separator paper material body 5 reaches the loading position of the separator paper material bin 24, the corresponding grabbing mechanism is activated to grab the separator paper material body 5, and then the separator paper material body 5 is moved along the main linear movable guide rail 1 to the corresponding loading assembly table, and the separator paper material body 5 is placed thereon to realize loading;

[0028] A movable slide 2 is slidably provided on the main linear movable guide rail 1, and a secondary linear movable guide rail 3 is fixedly connected to the movable slide rail 2. The secondary linear movable guide rail 3 is perpendicular to the main linear movable guide rail 1 and moves in the horizontal direction. A pneumatic telescopic rod 4 is slidably connected to the secondary linear movable guide rail 3. The pneumatic telescopic rod 4 moves up and down in the vertical plane. The bottom end of the pneumatic telescopic rod 4 is a telescopic end, and the telescopic end is connected to a vacuum suction cup assembly 6. The vacuum suction cup assembly 6 adsorbs the partition paper hopper 24 through the action of negative pressure;

[0029] The vacuum suction cup assembly 6 is provided with an anti-material-carrying mechanism, which includes an electric telescopic rod 25 and a one-way movable block 10. The electric telescopic rods 25 are distributed in pairs on both sides of the vacuum suction cup assembly 6. The two electric telescopic rods 25 are connected to the top of the pneumatic telescopic rod 4. Specifically, the top of the pneumatic telescopic rod 4 is horizontally connected to a horizontal hanging plate 26 through a rod body. A plurality of mounting screw holes 27 are equidistantly provided on the horizontal hanging plate 26. The two electric telescopic rods 25 are connected to the mounting screw holes 27 at corresponding positions by bolts, and the two electric telescopic rods 25 are symmetrically distributed. The spacing between the two electric telescopic rods 25 is adjusted according to the specifications of the partition paper to be adsorbed and loaded, and then installed on the mounting screw holes 27 at corresponding positions of the horizontal hanging plate 26;

[0030] The electric telescopic rod 25 and the pneumatic telescopic rod 4 operate simultaneously. When the pneumatic telescopic rod 4 extends downward, the electric telescopic rod 25 contracts. When the pneumatic telescopic rod 4 contracts, the electric telescopic rod 25 extends.

[0031] The telescopic end of the electric telescopic rod 25 is vertically fixedly connected to the vertical hanging plate 7, and the one-way movable stopper 10 is movably connected to the bottom of the vertical hanging plate 7 through a rebound hinge. The connecting end of the one-way movable stopper 10 is fitted on the vertical hanging plate 7, and the rebound hinge is installed at the upper edge of the connecting end, so that the one-way movable stopper 10 can only be rotated upward from the horizontal position and cannot be rotated downward to achieve restriction, and when loading, the one-way movable stopper 10 is in a position to contact the partition paper material body 5, and an air pump 8 is fixedly installed on the side of the bottom of the vertical hanging plate 7 away from the one-way movable stopper 10, and a linkage component is provided on the one-way movable stopper 10, which is connected to A pressure sensing switch 15 electrically connected to the air pump 8, and a linkage assembly including a rubber sliding plug 14. A connecting sliding hole 16 is provided on the one-way movable stopper 10. The rubber sliding plug 14 is slidably arranged in the connecting sliding hole 16. There is a certain friction between the rubber sliding plug 14 and the connecting sliding hole 16. When the one-way movable stopper 10 is in a horizontal position, the one-way movable stopper 10 cannot slide down under the action of gravity. A first linkage rope is connected between one end of the rubber sliding plug 14 and the vertical hanging plate 7. When the one-way movable stopper 10 is in a horizontal position, the rubber sliding plug 14 is above the connecting sliding hole 16, and the first linkage rope is in a taut state. The other end of the rubber sliding plug 14 is connected to a second linkage rope.

[0032] A rubber air tube 9 is connected to the side of the vertical hanging plate 7 close to the one-way movable stopper 10. The air outlet of the air pump 8 is connected to the rubber air tube 9. The rubber air tube 9 is above the one-way movable stopper 10. The one-way movable stopper 10 is provided with a flat air hole 28 that cooperates with the rubber air tube 9.

[0033] When the vacuum suction cup assembly 6 at the telescopic end of the pneumatic telescopic rod 4 adsorbs the partition paper material body 5 in the partition paper material bin 24, the pneumatic telescopic rod 4 contracts, driving the partition paper material body 5 to rise. When the partition paper material body 5 rises to the position of the one-way movable stopper 10, the partition paper material body 5 first pushes the one-way movable stopper 10 to rotate upward during the rising process. When the one-way movable stopper 10 rotates to the position of the vertical hanging plate 7, the pressure sensing switch 15 is squeezed and the air pump 8 is started. At this time, the flat air hole 28 on the one-way movable stopper 10 is fitted and docked with the rubber air tube 9, so that the pressure generated after the air pump 8 is started The airflow enters the flat air hole 28 through the rubber air tube 9, and then generates a horizontal airflow through the flat air hole 28 to act on the separator paper body 5 that is rising and passing through. If there is another piece of material attached to the bottom of the separator paper body 5, the horizontal airflow helps to separate the material attached to the bottom when entering between the two pieces of material, ensuring that one piece of separator paper body 5 is adsorbed at a time. When the separator paper body 5 rises to the set position and stops, it is higher than the one-way movable stopper 10, so that the one-way movable stopper 10 rotates and resets, thereby blocking the bottom edge of the separator paper body 5 to prevent it from falling during the transfer and loading process of the separator paper body 5;

[0034] An auxiliary suction and pulling mechanism is also provided below the one-way movable stopper 10, and the auxiliary suction and pulling mechanism includes an air cylinder 11, and the air cylinder 11 is fixedly connected to one side of the bottom of the one-way movable stopper 10 in parallel through a plate body, and one end of the air cylinder 11 away from the one-way movable stopper 10 is connected to the air outlet end of the air pump 8 through a hose, and a first air leakage hole 12 is provided on the air cylinder 11, and the leakage speed of the first air leakage hole 12 is less than the air intake speed of the air intake end of the air cylinder 11, and a piston column 13 is slidably inserted into the other end of the air cylinder 11, and the piston column 13 is connected to the end of the second linkage rope, and an auxiliary suction cup assembly is provided at the end of the piston column 13, and the auxiliary suction cup assembly includes a rubber suction cup 17, and one end of the rubber suction cup 17 is connected to a rubber sleeve 19, a rubber The rubber suction cup 17 is slidably mounted on the end of the piston column 13 through a rubber sleeve 19. It should be noted that the inner diameter of the rubber sleeve 19 in its original state is smaller than the outer diameter of the piston column 13. The rubber sleeve 19 is an elastic rubber body that can be stretched and then mounted on the piston column 13 to ensure a certain degree of stability during connection. A one-way air valve 18 is installed on the side wall of the rubber suction cup 17. The one-way air valve 18 only allows the air flow inside the rubber suction cup 17 to flow outward. A second air leakage hole 20 communicating with the inside of the rubber suction cup 17 is opened on the piston column 13. The rubber sleeve 19 can slide to close the position of the second air leakage hole 20. The adsorption force generated by the rubber suction cup 17 on the partition paper material 5 is less than the suction force generated by the vacuum suction cup assembly 6;

[0035] The end of the piston column 13 near the rubber suction cup 17 is connected to a limiting sleeve 21. The inner side of the rubber suction cup 17 is connected to a sliding column 22 through a rod body. The sliding column 22 slides and penetrates the limiting sleeve 21. The end of the sliding column 22 is fixedly connected to a limiting ball 23. The diameter of the limiting ball 23 is larger than the inner diameter of the limiting sleeve 21. The sliding column 22 facilitates the rubber suction cup 17 to slide to a certain extent relative to the piston column 13. The cooperation between the limiting ball 23 and the limiting sleeve 21 ensures that the rubber suction cup 17 relies on the rubber sleeve 19 to slide only within a certain range and cannot be separated from the piston column 13.

[0036] When the air pump 8 is started, it diverts a part of the air flow through the hose into the air cylinder 11. Since the one-way movable block 10 is attached to the end face of the vertical hanger 7 and is in a vertical position, the air cylinder 11 is also in a vertical position. Then the piston column 13 rises upward due to the rising air pressure in the air cylinder 11. It should be noted here that the rising speed of the piston column 13 under the action of air pressure is greater than the speed at which the pneumatic telescopic rod 4 drives the partition paper material body 5 to rise. In this way, the rubber suction cup 17 at the top of the piston column 13 pushes and presses against the edge bottom of the partition paper material body 5. When the rubber suction cup 17 is squeezed to the bottom of the partition paper material body 5, The air inside is discharged from the one-way air valve 18, and due to the squeezing, the rubber sleeve 19 connected to the rubber suction cup 17 slides downward relative to the end of the piston column 13, closing the second air leakage hole 20, so as to facilitate the generation of negative pressure in the rubber suction cup 17, thereby adsorbing the bottom of the partition paper body 5, and because the piston column 13 is connected to the second linkage rope, during the rising process of the piston column 13, the second linkage rope is pulled and straightened, and then pulls the rubber sliding plug 14. Since the one-way movable block 10 is now in contact with the vertical hanging plate 7, the first linkage rope between the rubber sliding plug 14 and the vertical hanging plate 7 When the air pump 8 stops, the gas in the cylinder 11 will continue to leak out through the first air leakage hole 12, that is, the air pressure inside the cylinder 11 gradually decreases. At this time, the cylinder 11 rotates to the vertical position with the one-way movable block 10, so the piston column 13 falls downward under the action of gravity, so that the bottom of the partition paper material body 5 can be pulled by the rubber suction cup 17. If the partition paper material There is another piece of material attached to the bottom of the body 5, which is separated due to pulling, and when the piston column 13 drops to a certain position, the rubber sleeve 19 separates and slides from the piston column 13, exposing the second air leakage hole 20, so that outside air can enter the inside of the rubber suction cup 17, relieving the negative pressure, facilitating the separation of the rubber suction cup 17 from the adsorbed material, and facilitating its return. When the one-way movable block 10 rotates and resets, the rubber sliding plug 14 slides back and resets relative to the connecting slide hole 16 under the action of the first linkage rope, facilitating the reset of the pressure sensing switch 15 for the next operation.

[0037] The working principle of the present invention is as follows: a sensor is provided in the partition paper material bin 24. When the partition paper material body 5 reaches the loading position of the partition paper material bin 24, the movable slide 2 moves to the corresponding position along the main linear movable guide rail 1, and then the secondary linear movable guide rail 3 drives the pneumatic telescopic rod 4 to move and align to the corresponding position. Finally, the pneumatic telescopic rod 4 is extended, so that the vacuum suction cup assembly 6 at the telescopic end descends to contact the partition paper material body 5, and then the partition paper material body 5 in the partition paper material bin 24 is adsorbed, and the pneumatic telescopic rod 4 is retracted again to drive the partition paper material body 5 to rise. When the partition paper material body 5 rises to the position of the one-way movable stopper 10, the partition paper material body 5 first pushes the one-way movable stopper 10 to rotate upward during the rising process. When the one-way movable stopper 10 rotates to the position of the vertical hanging plate 7, the pressure The induction switch 15 is squeezed to start the air pump 8. At this time, the flat air hole 28 on the one-way movable stopper 10 is fitted and docked with the rubber air tube 9. The airflow generated after the air pump 8 is started enters the flat air hole 28 through the rubber air tube 9, and then generates a horizontal airflow through the flat air hole 28 to act on the partition paper material body 5 that is rising and passing through. If there is another piece of material attached to the bottom of the partition paper material body 5, the horizontal airflow helps to separate the material attached to the bottom when entering between the two pieces of material, ensuring that one piece of partition paper material body 5 is adsorbed at a time. When the partition paper material body 5 rises to the set position and stops, it is higher than the one-way movable stopper 10. In this way, the one-way movable stopper 10 rotates and resets, thereby blocking the bottom edge of the partition paper material body 5 to prevent the partition paper material body 5 from falling during the transfer and loading process.

[0038] When the air pump 8 is started, it diverts a part of the air flow through the hose into the air cylinder 11. Since the one-way movable block 10 is attached to the end face of the vertical hanger 7 and is in a vertical position, the air cylinder 11 is also in a vertical position. Then the piston column 13 rises upward due to the rising air pressure in the air cylinder 11. It should be noted here that the rising speed of the piston column 13 under the action of air pressure is greater than the speed at which the pneumatic telescopic rod 4 drives the partition paper material body 5 to rise. In this way, the rubber suction cup 17 at the top of the piston column 13 pushes and presses against the edge bottom of the partition paper material body 5. When the rubber suction cup 17 is squeezed to the bottom of the partition paper material body 5, The air inside is discharged from the one-way air valve 18, and due to the squeezing, the rubber sleeve 19 connected to the rubber suction cup 17 slides downward relative to the end of the piston column 13, closing the second air leakage hole 20, so as to facilitate the generation of negative pressure in the rubber suction cup 17, thereby adsorbing the bottom of the partition paper body 5, and because the piston column 13 is connected to the second linkage rope, during the rising process of the piston column 13, the second linkage rope is pulled and straightened, and then pulls the rubber sliding plug 14. Since the one-way movable block 10 is now in contact with the vertical hanging plate 7, the first linkage rope between the rubber sliding plug 14 and the vertical hanging plate 7 When the air pump 8 stops, the gas in the cylinder 11 will continue to leak out through the first air leakage hole 12, that is, the air pressure inside the cylinder 11 gradually decreases. At this time, the cylinder 11 rotates to the vertical position with the one-way movable block 10, so the piston column 13 falls downward under the action of gravity, so that the bottom of the partition paper material body 5 can be pulled by the rubber suction cup 17. If the partition paper material Another piece of material is attached to the bottom of the body 5, which is separated due to the pulling, and when the piston column 13 drops to a certain position, the rubber sleeve 19 separates and slides from the piston column 13, exposing the second air leakage hole 20, so that the outside air can enter the inside of the rubber suction cup 17, releasing the negative pressure, facilitating the separation of the rubber suction cup 17 from the adsorbed material, and facilitating its return. When the one-way movable stopper 10 rotates and resets, the rubber sliding plug 14 slides back and resets relative to the connecting sliding hole 16 under the action of the first linkage rope, facilitating the reset of the pressure sensing switch 15, so as to facilitate the next operation;

[0039] When the pneumatic telescopic rod 4 extends downward to drop the partition paper material body 5 for loading, the electric telescopic rod 25 contracts to facilitate the one-way movable block 10 to be offset from the bottom of the partition paper material body 5 for loading.

[0040] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
