Description

Technical Field

[0001] The present invention relates to the technical field of spraying training, specifically an industrial robot spraying training platform. Background Technique

[0002] Among industrial robots, spraying robots are industrial robots that can perform automatic painting or spraying of other coatings. Spraying robots mainly consist of a robot body, a computer, and a corresponding control system. In school training teaching, students need to program the spraying robot to make it perform spraying operations as required.

[0003] Currently, during the training of spraying robots, in order to reduce learning costs and prevent pollution caused by paint, what the spraying robot sprays is not paint but pure water instead. Compared with paint, water has stronger diffusibility and will generate a certain amount of water mist during spraying. This water mist diffuses around, resulting in water stains appearing around the equipment. This not only affects students' observation but also makes it inconvenient to operate due to the attached water stains. Moreover, the water mist spreading everywhere is likely to damage other external training equipment. For this reason, we propose an industrial robot spraying training platform. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an industrial robot spraying training platform that can prevent the water stains generated during the spraying process from spreading everywhere, avoid affecting students' observation and operation, and at the same time can effectively prevent the water mist from damaging external training equipment, and can effectively solve the problems in the background technique.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This industrial robot spraying training platform has the following advantages:

[0019] 1. By setting up the water mist shielding component, during use, the manipulator can be started to adjust the spraying angle of the nozzle. After adjustment, the feeding pump can be started to pump the pure water stored in the storage box into the connecting hose, and then injected into the nozzle through the connecting hose and sprayed onto the product to be sprayed. During the spraying process, the transparent cover can effectively block the water mist, so that the water mist can be prevented from spreading everywhere and damaging the external training equipment.

[0020] 2. By setting up the wiping component, during the spraying process, the third motor can be started to make the front shaft rotate. During its rotation, the arc plate will be driven to rotate. The rotation of the arc plate drives the arc-shaped sponge strip to rotate, which can wipe the surface of the transparent cover, so that the water stains attached to the transparent cover can be prevented from affecting the observation and operation of students.

[0021] 3. By setting up the air extraction component, during the spraying process, the exhaust fan can be started. After the exhaust fan is started, the water mist generated during the spraying process is pumped into the L-shaped exhaust pipe through the conical pipe, and then discharged to the outside through the L-shaped exhaust pipe. In this way, the water mist content inside the transparent cover can be greatly reduced, and the water stains attached to the inside of the transparent cover can be effectively reduced.

[0022] 4. By setting up the moving component, before spraying, the two moving components can be started to drive the two L-shaped connecting bars to move upward. The upward movement of the two L-shaped connecting bars drives the fixed ring to move upward, so that the transparent cover moves upward away from the installation box. After moving away, the product to be sprayed can be placed on the placement net. Then, the first motor is started to make the bidirectional screw rotate, driving the two clamping plates to approach the product and fix it. After fixing, the stability of the product to be sprayed can be ensured, so as to avoid the product shaking during spraying. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Among them: The input end of the PLC controller 2 is electrically connected to the output end of an external power supply, and the output end of the PLC controller 2 is electrically connected to the input end of the pumping pump 35.

[0035] Among them: An anti-slip plate 10 is fixed on the side of the clamping plate 53, and evenly distributed anti-slip grooves are opened on the side of the anti-slip plate 10. The firmness of the clamping plate 53 for fixing the product to be sprayed is improved by setting the anti-slip plate 10.

[0036] Among them: an observation port is provided on the side of the storage tank 33, and a transparent plate 11 is fixed inside the observation port. By providing the transparent plate 11, it is convenient for users to observe the content of pure water inside the storage tank 33.

[0037] Among them: a feeding hole is provided on the upper side of the storage tank 33, and a feeding pipe 12 is fixed inside the feeding hole. The upper end of the feeding pipe 12 is threadedly connected with a sealing cover 13, and pure water enters the inside of the storage tank 33 through the feeding pipe 12.

[0038] The working principle of the industrial robot spraying training platform provided by the present invention is as follows: First, start two second motors 73 to make two gears 74 rotate. The rotation of the two gears 74 drives two sliding frames 72 to move upward under the action of two toothed plates 75. The upward movement of the two sliding frames 72 drives two L-shaped connecting bars 63 to move upward. The upward movement of the two L-shaped connecting bars 63 drives the fixed ring 62 to move upward, so that the transparent cover 61 moves upward away from the installation box 1. After moving away, the product to be sprayed can be placed on the placement net 51. After placement, start the first motor 52 to make the bidirectional screw 54 rotate, driving two clamping plates 53 to approach the product to fix it. After fixing, the two anti-slip plates 10 can effectively ensure the stability of the product to be sprayed. Then remove the sealing cover 13, and then inject pure water into the inside of the storage tank 33 through the feeding pipe 12. After injection, re-cover the sealing cover 13. Then, control the manipulator 41 to work through the PLC controller 2 to adjust the spraying angle of the spray head 44. After adjustment, start the pumping pump 35 to pump the pure water stored inside the storage tank 33 into the inside of the connecting hose 36, and then inject it into the spray head 44 through the connecting hose 36 and spray it on the product to be sprayed. During the spraying process, the transparent cover 61 can effectively block the water mist. In this case, it is possible to avoid the water mist spreading everywhere and damaging the external training equipment. At the same time, during the spraying process, start the third motor 91 and the exhaust fan 83 at the same time. After the third motor 91 is started, the front shaft 92 rotates. During its rotation, it will drive the arc plate 93 to rotate. The rotation of the arc plate 93 drives the arc-shaped sponge strip 94 to rotate, which can wipe the surface of the transparent cover 61. In this case, it is possible to avoid the water stains attached to the transparent cover 61 from affecting the observation and operation of students. After the exhaust fan 93 is started, the water mist generated during the spraying process is pumped into the inside of the L-shaped exhaust pipe 84 through the conical pipe 81, and then discharged to the outside through the L-shaped exhaust pipe 84. In this case, the water mist content inside the transparent cover 61 can be greatly reduced, thereby effectively reducing the water stains attached to the inside of the transparent cover 61.

[0039] It should be noted that the PLC controller 2 disclosed in the above embodiments is of the specific model Siemens S7-200. The first motor 52, the second motor 73, and the third motor 91 can be selected as 1LE0003 three-phase asynchronous motors, the material extraction pump 35 can be selected as the WQD6-12-0.55L1 water extraction pump, the exhaust fan 83 can be selected as the AUX-APB30-BS exhaust fan, and the robotic arm 41 can be selected as the YASKAWA 6-axis industrial robot.
