Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spraying robots, in particular to a plastic floor coil spraying robot. BACKGROUND

[0002] The spraying robot originates from the deep integration of industrial automation and robot technology, and its core is the high-precision trajectory control technology of multi-joint mechanical arm, which realizes flexible spraying of complex surfaces through servo motors and precision reducers; at the same time, it integrates a complete set of fluid control system, including gear pump, servo valve, etc., to ensure uniform atomization and stable paint output.

[0003] The patent with patent number CN101602034B relates to the technical field of spraying robots, including a spray gun, a curved arm, a telescopic arm and a base connected in sequence, and the sum of the degrees of freedom of the spray gun, the curved arm, the telescopic arm and the base is not less than 6; an air cushion transport vehicle, on which the robot is installed, the air cushion transport vehicle includes an air bag at the bottom, and the air bag is used to make the air cushion transport vehicle float, so as to coarsely position the system before entering the working area. The technical scheme of the present application realizes the spraying operation on the inner wall of the special-shaped long and narrow pipeline by designing the robot with multiple redundant degrees of freedom, and improves the efficiency of the preparation work before the spraying operation.

[0004] The above-mentioned patent realizes the spraying operation on the inner wall of the special-shaped long and narrow pipeline and improves the efficiency of the preparation work before the spraying operation, although it can realize automatic spraying operation, but it has obvious defects in the connection and installation positioning of the spray pipe. Since the connection between the spray pipe and the water outlet pipe is only fixed by simple threads or buckles, there is a lack of active sealing structure, which is easy to leak under the long-term scouring of high-pressure ink, not only causing waste of expensive ink and environmental pollution, but also causing internal pressure fluctuation of the spraying system, seriously affecting the stability and uniformity of the spraying quality. In addition, when installing the spray pipe, the rotating part of the actuator lacks an effective locking device, so that the spray pipe interface is easy to deviate during the butt joint process, which not only greatly increases the difficulty and time of installation alignment, but also easily causes scratching or collision damage to the precise alignment interface, shortening the service life of the key components.

[0045] The fixing device further comprises that one side of the sliding block 10 and the fixing block 12 close to each other is provided with an inclined surface, the sliding block 10 and the fixing block 12 are provided with the inclined surface so as to facilitate the sliding block 10 to push the fixing block 12 to move, one side of the limiting plate 13 close to the fixed plate 8 is provided with an inclined surface, the limiting plate 13 is provided with the inclined surface so as to facilitate the fixed plate 8 to push the limiting plate 13 to move, one side of the positioning plate 123 close to the sliding plate 121 is provided with an inclined surface, the positioning plate 123 is provided with the inclined surface so as to facilitate the sliding plate 121 to push the positioning plate 123 to move downward, one side of the positioning plate 123 close to the sliding plate 124 is provided with an inclined surface, the positioning plate 123 is provided with the inclined surface so as not to be blocked when the sliding plate 124 resets, a spring one is arranged between the sliding plate 124 and the supporting plate 125, the spring one is arranged so as to drive the sliding plate 124 to move toward the supporting plate 125, and a spring two is arranged between the positioning plate 123 and the rotating plate 5, the spring two is arranged so as to drive the positioning plate 123 to move upward.

[0046] When the surface of the object needs to be sprayed, the operator controls the movement of the main arm 1, moves the spray pipe 7 towards the object, and moves the support arm 2 and the rotating plate 3 to enable the spray pipe 7 to align with the surface of the object. When aligned, the ink suction pipe 4 draws the ink into the outlet pipe 6, and the ink drawn into the outlet pipe 6 is sprayed out through the spray pipe 7 to spray the surface of the object. When the spray pipe 7 is used for a long time, a layer of scab may be formed inside the spray pipe 7 due to the evaporation of the residual ink, which may cause blockage of the spray pipe 7. Therefore, after use, the spray pipe 7 needs to be disassembled for cleaning, and then reinstalled for next use. When installing the spray pipe 7 on the surface of the rotating plate 5, the square slot on the surface of the fixing plate 8 needs to be aligned with the fixing key 9, so that the fixing key 9 can be accurately inserted into the square slot. When the fixing plate 8 is fixed to the surface of the rotating plate 5, it will come into contact with the sliding block 10, and then the fixing plate 8 will push the sliding block 10 to move towards the inside of the outlet pipe 6. The movement of the sliding block 10 will come into contact with the inclined surface of the fixed block 12, and then the sliding block 10 will push the fixed block 12 to move. The movement of the fixed block 12 will push the sealing plate 11 to move, and the movement of the sealing plate 11 will come into contact with the inner wall of the spray pipe 7 to strengthen the sealing between the spray pipe 7 and the outlet pipe 6. Through the tight contact between the sealing plate 11 and the inner wall of the spray pipe 7, the sealing of the connection between the spray pipe 7 and the outlet pipe 6 is actively and mechanically strengthened, greatly reducing the risk of leakage of high-pressure ink from the connection, avoiding waste of ink and environmental pollution, ensuring the airtightness of the ink flow path, thereby maintaining the stability of the internal pressure of the spraying system. When the fixing plate 8 moves, it will come into contact with the inclined surface of the limiting plate 13, and then the fixing plate 8 will push the limiting plate 13 to move away from the outlet pipe 6. When the position of the limiting plate 13 coincides with the insertion slot, the limiting plate 13 will move towards the inner wall of the insertion slot to fix the fixing plate 8. Without tools, the fixing plate 8 can be fixed by the limiting plate 13, which is more convenient and improves the installation efficiency and reduces the complexity of the operation. When the limiting plate 13 moves away from the outlet pipe 6, it will pull the connecting rod 122 to move, the movement of the connecting rod 122 will pull the sliding plate 121 to move, the movement of the sliding plate 121 will remove the blockage of the positioning plate 123, and then the positioning plate 123 will move away from the sliding plate 124. Then the limiting of the sliding plate 124 by the positioning plate 123 is removed, and then the sliding plate 124 will move towards the supporting plate 125, so that the rotating plate 5 can be rotated after the installation of the spray pipe 7 is completed. During the installation of the spray pipe 7, the rotating plate 5 is forcibly locked and cannot be rotated. Only when the spray pipe 7 is completely pushed in and locked by the limiting plate 13, the rotating plate 5 can be rotated, ensuring that the square slot on the fixing plate 8 can be quickly and accurately aligned with the fixing key 9. If the rotating plate 5 can swing freely during docking, the difficulty of alignment will be greatly increased, avoiding the hard scraping or collision of the edges of the square slot of the fixing plate 8 by the fixing key 9 due to the accidental rotation of the rotating plate 5, protecting the precise alignment interface and prolonging its service life.
