Description

Technical Field

[0001] The present invention relates to the field of plate unloading machines, and in particular to an intelligently controlled suction cup type plate unloading machine and a method thereof. Background Art

[0002] A plate unloader is a device widely used in industrial production, used to move plates, workpieces or PCB boards from one position to another. During the production process, a plate unloader is often used to remove the plates, workpieces or PCB boards from the conveyor belt of the conveying equipment and transfer them to another position. The existing plate unloader usually starts an electric lifting rod to move up and down, and the electric lifting rod can drive the mounting frame to descend, thereby driving the suction cup to descend. The plates, workpieces or PCB boards are adsorbed and transported by multiple sets of suction cups, thereby achieving the effect of transporting and unloading the plates. The multiple sets of suction cups in the existing plate unloader are often used in conjunction with equipment such as a vacuum pump. The vacuum pump is used to extract the air between the suction cup and the surface of the object, thereby creating this negative pressure area. Without a vacuum pump, the suction cup cannot generate sufficient suction force. However, impurities are inevitably present on the surface of the plate, workpiece, or PCB conveyed by the conveying equipment. After long-term use of the unloader, these impurities will inevitably be sucked into the suction cup or even the vacuum pump, causing the suction cup to be clogged. This will inevitably affect the normal use of the unloader and affect the normal adsorption and transportation of the plate, workpiece, or PCB by the suction cup. Therefore, after use, the operator of the existing unloader device needs to clean the suction cup and other components to ensure that the impurities are removed. The existing unloader device also has a filtering structure set in the suction cup to filter impurities, but some of the filtered impurities will be adsorbed on the filtering structure and need to be cleaned after use. Some unloader devices also use a cleaning structure to clean the filtering structure, but it is difficult to install the cleaning structure in the space available in the suction cup, which is difficult to assemble and produce the device. In addition, the cleaning structure is set in the suction cup, and the obstruction of the cleaning structure will also affect the normal adsorption of the plate, workpiece, or PCB by the suction cup. Therefore, an intelligent control suction cup unloader and a method thereof are proposed. Summary of the Invention

[0012] The present invention also provides a method for intelligently controlling a suction cup type unloader, which is characterized by comprising the following specific steps:

[0013] S1. When in use, the camera is wirelessly connected to the computer. The camera transmits the image of the plate, workpiece or PCB board being transported by the conveying equipment to the computer. The computer analyzes the angle of the plate, workpiece or PCB board, and then controls servo motor 1 to rotate and adjust the overall angle of the four sets of suction cups so that after the four sets of suction cups move down, the four sets of suction cups can effectively adsorb and adhere to the upper surface of the plate, workpiece or PCB board.

[0014] S2. When all four sets of suction cups can effectively adsorb and adhere to the upper surface of the plate, workpiece, or PCB, solenoid valves 1 and 2 are opened, and solenoid valves 3 and 4 are closed. Starting the vacuum pump will enable the four sets of suction cups to effectively adsorb the plate, workpiece, or PCB, and the air exhausted by the vacuum pump will be discharged through the outlet pipe 1. Since the internal diameter of the outlet pipe 1 gradually decreases from one end connected to the vacuum pump to the other end, the temperature of the air discharged from the outlet pipe 1 will decrease, and the air discharged from the outlet pipe 1 will blow onto the vacuum pump and accelerate the heat dissipation of the vacuum pump. In addition, during the process of the suction cups adsorbing the plate, workpiece, or PCB, the filter will filter out impurities.

[0015] S3. After the four sets of suction cups effectively adsorb the plate, workpiece or PCB, the electric push rod is started to drive the plate, workpiece or PCB to move upward, and then the servo motor 2 is started to drive the plate, workpiece or PCB to move horizontally. When the plate, workpiece or PCB is moved horizontally to a suitable position, the electric push rod is started again to drive the plate, workpiece or PCB to move downward to a suitable position, and then the vacuum pump is stopped so that the four sets of suction cups cannot adsorb the plate, workpiece or PCB, and the plate, workpiece or PCB is placed in a suitable position.

[0016] S4. After use, solenoid valve 1 and solenoid valve 2 are closed, and solenoid valve 3 and solenoid valve 4 are opened. At this time, starting the vacuum pump will draw the dry air in the drying box into the vacuum pump, and the original air in the vacuum pump will be discharged, making the air in the vacuum pump dry, which is beneficial for the vacuum pump to extend the life of the equipment and maintain the vacuum quality. At this time, the air discharged by the vacuum pump will enter the air box through the air outlet pipe 1 and the air outlet pipe 2. The air in the air box passes through the spring tube and the vent and is finally discharged from the suction cup. After the air is discharged from the suction cup, the impurities adsorbed on the lower surface of the filter will be blown off and blown out of the suction cup under the drive of air flow.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the present invention is in use, solenoid valve 1 and solenoid valve 2 are opened, and solenoid valve 3 and solenoid valve 4 are closed. At this time, starting the vacuum pump will enable the four groups of suction cups to effectively adsorb the plate, workpiece or PCB board, and the air discharged by the vacuum pump will be discharged through the air outlet pipe 1. Since the internal diameter of the air outlet pipe 1 gradually decreases from one end connected to the vacuum pump to the other end, the temperature of the air discharged by the air outlet pipe 1 will decrease, and the air discharged by the air outlet pipe 1 will blow on the vacuum pump and accelerate the heat dissipation of the vacuum pump, thereby achieving the effects of improving the use efficiency of the vacuum pump and extending the service life of the vacuum pump; and in the process of the suction cup adsorbing the plate, workpiece or PCB board, the filter screen filters and intercepts impurities; after the device is used, the solenoid valve 1 and solenoid valve 2 are closed, and the solenoid valve 3 is opened When the solenoid valve 4 is opened, the vacuum pump is started to draw the air dried in the drying box into the vacuum pump, and the original air in the vacuum pump is discharged, making the air in the vacuum pump dry, which is beneficial to the vacuum pump in extending the life of the equipment and maintaining the vacuum quality. At this time, the air discharged by the vacuum pump enters the air box through the outlet pipe 1 and the outlet pipe 2. The air in the air box passes through the spring tube and the breather and is finally discharged from the suction cup. After the air is discharged from the suction cup, the impurities adsorbed on the lower surface of the filter are blown off and blown out of the suction cup by the air flow. Then, the vacuum pump automatically removes the impurities attached to the filter. Therefore, the vacuum pump in the device of the present invention can achieve different usage effects and meet different usage requirements under different usage environments.

[0038] The present invention also provides a method for intelligently controlling a suction cup type unloader, which is characterized by comprising the following specific steps:

[0039] S1. During use, the camera 1602 is wirelessly connected to the computer. The camera 1602 transmits the image of the plate, workpiece, or PCB being transported on the conveying device to the computer. The computer analyzes the angle of the plate, workpiece, or PCB and then controls the servo motor 1604 to rotate and adjust the overall angle of the four sets of suction cups 10 so that after the four sets of suction cups 10 move downward, the four sets of suction cups 10 can effectively adhere to the upper surface of the plate, workpiece, or PCB.

[0040] S2. When the four sets of suction cups 10 can effectively adsorb and adhere to the upper surface of the plate, workpiece or PCB, the solenoid valve 1 5 and the solenoid valve 2 13 are opened, the solenoid valve 3 15 and the solenoid valve 4 605 are closed, and the vacuum pump 2 is started, so that the four sets of suction cups 10 can effectively adsorb the plate, workpiece or PCB, and the air exhausted by the vacuum pump 2 will be discharged through the outlet pipe 12. Since the internal diameter of the outlet pipe 12 gradually decreases from one end connected to the vacuum pump 2 to the other end, the temperature of the air discharged by the outlet pipe 12 will decrease, and the air discharged by the outlet pipe 12 will blow on the vacuum pump 2 and accelerate the heat dissipation of the vacuum pump 2; and in the process of the suction cups 10 adsorbing the plate, workpiece or PCB, the filter 11 will filter and intercept impurities;

[0041] S3. After the four sets of suction cups 10 effectively adsorb the plate, workpiece, or PCB, the electric push rod 26 is started to drive the plate, workpiece, or PCB to move upward, and then the servo motor 2 32 is started to drive the plate, workpiece, or PCB to move horizontally. When the plate, workpiece, or PCB is moved horizontally to a suitable position, the electric push rod 26 is started again to drive the plate, workpiece, or PCB to move downward to a suitable position. Then, the vacuum pump 2 is stopped so that the four sets of suction cups 10 cannot adsorb the plate, workpiece, or PCB, and the plate, workpiece, or PCB is placed at a suitable position.

[0042] S4. After use, solenoid valve 1 5 and solenoid valve 2 13 are closed, and solenoid valve 3 15 and solenoid valve 4 605 are opened. At this time, starting the vacuum pump 2 will draw the air dried in the drying box 601 into the vacuum pump 2, and the original air in the vacuum pump 2 will be discharged, making the air in the vacuum pump 2 dry, which is beneficial for the vacuum pump 2 to achieve the effects of extending the equipment life and maintaining the vacuum quality. At this time, the air discharged by the vacuum pump 2 will enter the air box 4 through the air outlet pipe 1 12 and the air outlet pipe 2 14. The air in the air box 4 passes through the spring tube 8 and the vent 9 and is finally discharged from the suction cup 10. After the air is discharged from the suction cup 10, the impurities adsorbed on the lower surface of the filter 11 will be blown off and blown out of the suction cup 10 under the drive of the air flow.

[0043] The working principle of the present invention is as follows: when in use, the servo motor 2 32 drives the lifting frame 1601 to move horizontally to a suitable position, so that the shooting range of the camera 1602 is just aligned with the lower plate position of the plate, workpiece or PCB board conveying device, and the camera 1602 is wirelessly connected to the computer. The camera 1602 transmits the image of the plate, workpiece or PCB board conveyed on the conveying device to the computer, and the computer analyzes the angle of the plate, workpiece or PCB board. Then the computer can control the servo motor 1 1604, and the servo motor 1 1604 is automatically started by the computer and driven by two sets of mutually meshing gears 1605. The rotation of the rotating column 1603 drives the rotating plate 1 to rotate, and then the overall angle of the four sets of suction cups 10 is rotated to adjust the overall angle of the four sets of suction cups 10, so that after the four sets of suction cups 10 move down, the four sets of suction cups 10 can effectively adsorb and adhere to the upper surface of the plate, workpiece or PCB board. Then, the servo motor 2 32 drives the lifting frame 1601 to move, so that the four sets of suction cups 10 are just above the plate, workpiece or PCB board.

[0044] After that, starting the electric push rod 26 can drive the lifting frame 1601 to move downward. The downward movement of the lifting frame 1601 will drive the rotating plate 1 to move downward, and then drive the four groups of suction cups 10 to move downward, so that the four groups of suction cups 10 can effectively adsorb and adhere to the upper surface of the plate, workpiece or PCB board. Then starting the vacuum pump 2 (at this time, the solenoid valve 1 5 and the solenoid valve 2 13 are open, and the solenoid valve 3 15 and the solenoid valve 4 605 are closed) will enable the four groups of suction cups 10 to effectively adsorb the plate, workpiece or PCB board, and the air exhausted by the vacuum pump 2 will be discharged through the air outlet pipe 12. Since the internal diameter of the air outlet pipe 12 gradually decreases from one end connected to the vacuum pump 2 to the other end, the temperature of the air discharged from the air outlet pipe 12 will decrease, and the air discharged from the air outlet pipe 12 will blow on the vacuum pump 2 and accelerate the heat dissipation of the vacuum pump 2; and in the process of the suction cup 10 adsorbing the plate, workpiece or PCB board, the filter 11 will filter and intercept impurities.

[0045] After the four groups of suction cups 10 effectively adsorb the plate, workpiece or PCB board, the electric push rod 26 is started to drive the plate, workpiece or PCB board to move upward, and then the servo motor 2 32 is started to drive the plate, workpiece or PCB board to move horizontally. When the plate, workpiece or PCB board moves horizontally to a suitable position, the electric push rod 26 is started again to drive the plate, workpiece or PCB board to move downward to a suitable position, and then the vacuum pump 2 is stopped, so that the four groups of suction cups 10 cannot adsorb the plate, workpiece or PCB board, and then the plate, workpiece or PCB board is placed at a suitable position;

[0046] After the device is used, solenoid valve 1 5 and solenoid valve 2 13 are closed, and solenoid valve 3 15 and solenoid valve 4 605 are opened. At this time, starting the vacuum pump 2 will draw the dry air in the drying box 601 into the vacuum pump 2, and the original air in the vacuum pump 2 will be discharged, making the air in the vacuum pump 2 dry, which is beneficial for the vacuum pump 2 to achieve the effects of extending the equipment life and maintaining the vacuum quality. At this time, the air discharged by the vacuum pump 2 will enter the air box 4 through the air outlet pipe 1 12 and the air outlet pipe 2 14. The air in the air box 4 passes through the spring tube 8 and the vent 9 and is finally discharged from the suction cup 10. After the air is discharged from the suction cup 10, the impurities adsorbed on the lower surface of the filter 11 will be blown off and blown out of the suction cup 10 under the drive of the air flow.
