Technical Field

[0001] The present invention relates to a construction method for ceiling decoration, and particularly to a manipulator for ceiling decoration construction applied to the field of decoration manipulators and its usage method. Background Art

[0002] A ceiling refers to a kind of decoration for the top decoration of a housing living environment. Simply put, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration. The ceiling has the functions of heat preservation, heat insulation, sound insulation, and sound absorption, and is also a concealed layer for projects such as electrical, ventilation and air conditioning, communication, and fire prevention and alarm pipeline equipment. Traditional manual ceiling work usually requires the cooperation of multiple ceiling workers, with low efficiency and high labor intensity.

[0003] The specification of Patent CN201720468803.9 discloses a ceiling decoration construction robot. By adjusting the height of the vertical thin rod, the height and levelness of the H-shaped three-axis right-angle coordinate automatic manipulator can be controlled, and then the vertical thin rod is fixed with fastening bolts. A distance sensor is installed on the H-shaped three-axis right-angle coordinate automatic manipulator, and different working tools are installed on the Z-axis linear slide table with a motor, and the robot realizes different types of automated decoration construction operations.

[0004] Existing ceiling robots are usually used to assist ceiling workers in ceiling work. Most of them are large-scale machines, and their operation requires the cooperation of multiple people. The operation is cumbersome and requires ceiling workers to receive certain training to master it proficiently. It is suitable for large-area roof decoration work in exhibition halls and factories, and cannot meet the needs of ceiling decoration for the housing of a small number of ceiling workers. Summary of the Invention

[0005] Aiming at the above-mentioned existing technologies, the technical problem to be solved by the present invention is that the operation of the existing ceiling robot requires the cooperation of multiple people, the operation is cumbersome, and ceiling workers need to receive certain training to master it proficiently, and it cannot meet the needs of ceiling decoration for the housing of a small number of ceiling workers.

[0006] To solve the above problems, the present invention provides a manipulator for ceiling decoration construction, including a moving base, a hydraulic rod is fixedly connected to the upper end of the moving base, a rotating unit is fixedly connected to the upper end of the hydraulic rod, a support shaft is rotatably connected in the rotating unit, a pair of sliding rings are slidably connected to the support shaft, support bars are fixedly connected to the upper ends of the two sliding rings, and electric vacuum suckers are slidably connected to the two support bars;

[0007] Its usage method includes:

[0008] S1. Ceiling board trimming, the ceiling worker continues to measure the position where the ceiling is needed, and according to the measurement results, the main body of the ceiling board is trimmed so that the size and shape of the main body of the ceiling board meet the requirements of ceiling work;

[0009] S2. Hoisting plate feeding: Move the mobile base to directly below the ceiling construction position, start the hydraulic rod to drive the support shaft and the support bar to move downward, so that the height of the support shaft drops to the waist of the ceiling worker. Use the rotation unit to drive the support shaft to rotate until both support bars are perpendicular to the ground. Then, the ceiling worker transports the main body of the hoisting plate that has been trimmed in step S1 to the multiple electric vacuum suction cups and makes the main body of the hoisting plate fit with the suction cup working part. Start the multiple electric vacuum suction cups to form a negative pressure state between the electric vacuum suction cups and the main body of the hoisting plate, so that the main body of the hoisting plate is fixed in the middle of the multiple electric vacuum suction cups;

[0010] S3. Hoisting plate installation: Start the rotation unit, use the support shaft to drive the support bar and the electric vacuum suction cups to rotate, so that the main body of the hoisting plate rotates to the required angle. Then start the hydraulic rod to lift the main body of the hoisting plate to the ceiling position. After manual fine-tuning and calibration by the ceiling worker, use a pneumatic nail gun to fix the main body of the hoisting plate to the pre-laid ceiling frame. Start the electric vacuum suction cups again to release the fixation between the electric vacuum suction cups and the main body of the hoisting plate. Then repeat step S1 for hoisting plate trimming until the entire ceiling work is completed.

[0011] In the above-mentioned manipulator for ceiling decoration construction and its use method, the operation process only requires a few workers to complete, the operation steps are simple, and it is suitable for ceiling work in small-area housing.

[0012] As a further improvement of this application, when the main body of the hoisting plate is a special-shaped plate, use the sliding ring to adjust the positions of the two support bars so that the two support bars are asymmetrically distributed. After the main body of the hoisting plate is fixed by the electric vacuum suction cups, the center of gravity position of the main body of the hoisting plate matches the position of the rotation unit, making the load of the rotation unit and the support shaft relatively balanced, not easily causing the phenomenon of unstable center of gravity during the installation of the special-shaped main body of the hoisting plate, and not easily leading to accidents of the overall side overturning of the manipulator.

[0013] As a further improvement of this application, the support shaft includes a shaft body. An electric chute is dug at the lower end of the shaft body. The sliding ring includes a ring body sleeved outside the shaft body. The inner wall of the ring body is fixedly connected with an electric slider that matches the electric chute. The cooperation of the electric chute and the electric slider enables the two support bars to move axially along the support shaft for adjustment, facilitating the installation work of hoisting plates with different sizes and special-shaped main bodies.

[0014] As a further improvement of the present application, the support bar includes a steel bar body. A sliding groove is drilled at the lower end of the steel bar body. An electric vacuum suction cup is sleeved outside the steel bar body. The electric vacuum suction cup includes a suction cup working part. A suction cup handle matching the steel bar body is fixedly connected to the lower side of the suction cup working part. A screw head is arranged on the lower side of the suction cup handle. A screw rod is fixedly connected to the upper end of the screw head. The screw rod penetrates through the suction cup handle and is threadedly connected with a locking nut. A compression spring is sleeved outside the screw rod. Two ends of the compression spring are respectively in contact with the locking nut and the suction cup handle. The electric vacuum suction cup is fixed by the pressure generated by the compression spring in a compressed state on the inner wall of the locking nut and the sliding groove. At the same time, the fixing can be released by lifting the screw head to move the position of the electric vacuum suction cup, which is convenient for adapting to the installation of different sizes and irregular hanging plate bodies.

[0015] As a supplement to the further improvement of the present application, an installation groove matching the size of the locking nut is drilled at the lower end of the steel bar body, and the installation groove communicates the sliding groove with the outside. The electric vacuum suction cup as a whole can be moved out from the installation groove by pulling the screw head, which is convenient for charging and maintenance work of the electric vacuum suction cup. At the same time, it is also convenient to temporarily add an electric vacuum suction cup to increase the reliability of fixing the hanging plate body.

[0016] As a supplement to the further improvement of the present application, an elliptical groove is drilled on the outer wall of the screw head, which is convenient for ceiling workers to hold the screw head to move the electric vacuum suction cup.

[0017] As a supplement to the further improvement of the present application, scale lines are drilled on the side wall of the steel bar body, and the scale lines take the connection point of the sliding ring and the support bar as the origin, which is convenient for ceiling workers to quantitatively adjust the position of the electric vacuum suction cup.

[0018] As another improvement of the present application, the manipulator further includes an auxiliary positioning module. The auxiliary positioning module includes a lighting unit and a photosensitive unit fixedly connected to the steel bar body. The position of the photosensitive unit matches the position of the installation groove. The lighting unit includes a rubber shell.

The auxiliary positioning work is realized by adding the photosensitive unit and the lighting unit, greatly reducing the operation difficulty of the manipulator for ceiling decoration construction and improving the usability of the equipment.

[0019] In summary, in the present application, the cooperation of the support shaft, the support bar and the electric vacuum suction cup is used to fix the main body of the hanging board to be installed, and it is transferred to the predetermined installation position by the hydraulic rod. Finally, the ceiling worker uses a nail gun to complete the fixing work. This operation process only requires a few workers to complete, and the operation steps are simple. It is suitable for the ceiling work of small-area housing. At the same time, the movable support bar and the electric vacuum suction cup can also adapt to the installation work of the special-shaped hanging board main body, making the load of the rotating unit and the support shaft relatively balanced, and it is not easy to cause an accident that the manipulator as a whole topples over due to unstable center of gravity during the installation of the special-shaped hanging board main body. At the same time, the auxiliary positioning work is realized by adding a photosensitive unit and a lighting unit, greatly reducing the operation difficulty of the manipulator for ceiling decoration construction and improving the usability of the equipment.

Specific embodiments

[0033] The following describes two embodiments of the present application in detail with reference to the accompanying drawings.

[0034] The first embodiment:

[0035] Figure 1 and Figure 3 There is shown a manipulator for ceiling decoration construction, including a mobile base 1, the upper end of the mobile base 1 is fixedly connected with a hydraulic rod 2, the upper end of the hydraulic rod 2 is fixedly connected with a rotating unit 3, a support shaft 4 is rotatably connected in the rotating unit 3, a pair of sliding rings 5 are slidably connected on the support shaft 4, the upper ends of the two sliding rings 5 are both fixedly connected with support bars 6, wherein the sliding ring 5 and the support bar 6 are fixedly connected by bolts, and electric vacuum suction cups 7 are slidably connected on both support bars 6;

[0036] Its usage method includes:

[0037] S1. Hanging plate trimming. The ceiling worker continues to measure the position where the ceiling is to be installed, and according to the measurement results, trims the hanging plate main body 9 so that the size and shape of the hanging plate main body 9 meet the requirements of the ceiling installation work;

[0038] S2. Hanging plate loading. Move the mobile base 1 to directly below the ceiling construction position, start the hydraulic rod 2 to drive the support shaft 4 and the support bar 6 to move downward, so that the height of the support shaft 4 drops to the waist of the ceiling worker. Use the rotating unit 3 to drive the support shaft 4 to rotate until both support bars 6 are perpendicular to the ground. Then the ceiling worker transports the hanging plate main body 9 trimmed in step S1 to the plurality of electric vacuum suction cups 7 and makes the hanging plate main body 9 fit with the electric vacuum suction cups 7. Start the plurality of electric vacuum suction cups 7 to form a negative pressure state between the electric vacuum suction cups 7 and the hanging plate main body 9, so that the hanging plate main body 9 is fixed in the middle of the plurality of electric vacuum suction cups 7;

[0039] S3. Install the suspended ceiling board. Start the rotating unit 3, drive the support bar 6 and the electric vacuum suction cup 7 to rotate by means of the support shaft 4, so that the main body 9 of the suspended ceiling board rotates to the required angle. Then start the hydraulic rod 2, lift the main body 9 of the suspended ceiling board to the ceiling position. After manual fine-tuning and calibration by the ceiling workers, use a nail gun to fix the main body 9 of the suspended ceiling board to the pre-laid ceiling frame. Start the electric vacuum suction cup 7 again to release the fixation between the electric vacuum suction cup 7 and the main body 9 of the suspended ceiling board. Then repeat step S1 to trim the suspended ceiling board until the overall ceiling installation work is completed.

[0040] Please refer to Figure 2 , when the main body 9 of the suspended ceiling board is a special-shaped plate, use the sliding ring 5 to adjust the positions of the two support bars 6 so that the two support bars 6 are asymmetrically distributed. After the main body 9 of the suspended ceiling board is fixed by the electric vacuum suction cup 7, the center of gravity position of the main body 9 of the suspended ceiling board matches the position of the rotating unit 3, making the load of the rotating unit 3 and the support shaft 4 relatively balanced, and it is not easy to have the phenomenon of unstable center of gravity during the installation of the special-shaped main body 9 of the suspended ceiling board, and it is not easy to cause an accident of the overall rollover of the manipulator.

[0041] Please refer to Figures 3 - 5 and Figure 7 , the support shaft 4 includes a shaft body 401. An electric chute 402 is opened at the lower end of the shaft body 401. The sliding ring 5 includes a ring body 501 sleeved outside the shaft body 401. An electric slider 502 matched with the electric chute 402 is fixedly connected to the inner wall of the ring body 501. The cooperation of the electric chute 402 and the electric slider 502 enables the two support bars 6 to move and adjust along the axial direction of the support shaft 4, facilitating the installation work of suspended ceiling boards with different sizes and special shapes of the main body 9.

[0042] Please refer to Figure 4 , Figure 6 and Figure 8, the support bar 6 includes a steel bar body 601. A sliding groove 602 is formed at the lower end of the steel bar body 601. An electric vacuum suction cup 7 is sleeved outside the steel bar body 601. The electric vacuum suction cup 7 includes an electric vacuum suction cup 701. A suction cup handle 702 matching the steel bar body 601 is fixedly connected to the lower side of the electric vacuum suction cup 701. A screw head 703 is provided on the lower side of the suction cup handle 702. A screw rod 704 is fixedly connected to the upper end of the screw head 703. The screw rod 704 penetrates through the suction cup handle 702 and is threadedly connected with a locking nut 705. A compression spring 706 is sleeved outside the screw rod 704. Two ends of the compression spring 706 are respectively in contact with the locking nut 705 and the suction cup handle 702. Among them, only one end of the screw rod 704 far from the screw head 703 is formed with threads. The screw rod 704 is only inserted into the suction cup handle 702. The electric vacuum suction cup 7 is fixed by the pressure generated by the compression spring 706 in a compressed state on the inner wall of the locking nut 705 and the sliding groove 602. At the same time, the fixation can be released by lifting the screw head 703, and the position of the electric vacuum suction cup 7 can be moved to conveniently adapt to the installation of different sizes and special-shaped hanging plate bodies 9.

[0043] An installation groove 603 matching the size of the locking nut 705 is formed at the lower end of the steel bar body 601, and the installation groove 603 communicates the sliding groove 602 with the outside. The whole electric vacuum suction cup 7 can be moved out of the installation groove 603 by pulling the screw head 703, which is convenient for charging and maintenance work of the electric vacuum suction cup 7. At the same time, it is also convenient to temporarily add an electric vacuum suction cup 7 to increase the reliability of fixing the hanging plate body 9. An elliptical groove is formed on the outer wall of the screw head 703, which is convenient for ceiling workers to hold the screw head 703 to move the electric vacuum suction cup 7. Scale lines are formed on the side wall of the steel bar body 601, and the scale lines take the connection point of the sliding ring 5 and the support bar 6 as the origin, which is convenient for ceiling workers to quantitatively adjust the position of the electric vacuum suction cup 7.

[0044] Particularly, the electric-related structures in this application include but are not limited to the control and power supply of the moving base 1, the hydraulic rod 2, the rotating unit 3, the support bar 6, and the electric vacuum suction cup 7, which are all well-known technologies to those skilled in the art. Those skilled in the art can make reasonable designs according to the existing technologies to meet the practical requirements of this application. Therefore, the power supply and control of each electric-related structure are not described in detail in this application. The cooperation between the rotating unit 3 and the support shaft 4 is similar to the cooperation at the rotating joint of the existing robotic arm.

[0045] In this embodiment, by using the cooperation of the support shaft 4, the support bar 6 and the electric vacuum suction cup 7, the main body 9 of the hanging plate to be installed is fixed, and it is transferred to the predetermined installation position by the hydraulic rod 2. Finally, the ceiling worker uses a nail gun to complete the fixing work. This operation process only requires a few workers to complete, the operation steps are simple, and it is suitable for the ceiling work of small-area housing. At the same time, the movable support bar 6 and the electric vacuum suction cup 7 can also adapt to the installation work of the special-shaped hanging plate main body 9, making the load of the rotating unit 3 and the support shaft 4 relatively balanced, and it is not easy to cause an accident that the whole manipulator overturns due to unstable center of gravity during the installation of the special-shaped hanging plate main body 9.

[0046] The second embodiment:

[0047] Figures 9 - 10 A manipulator for ceiling decoration construction is shown, which further includes an auxiliary positioning module. The auxiliary positioning module includes a lighting unit 8 and a photosensitive unit 604 fixedly connected to the steel strip 601. The position of the photosensitive unit 604 matches the position of the installation groove 603. The lighting unit 8 includes a rubber shell 801. A magnetic ring 804 is fixedly connected to the outer wall of the rubber shell 801. The magnetic ring 804 is adsorbed to the steel strip 601. A fixing nail 802 is fixedly connected to the upper end of the rubber shell 801, and a light-emitting lamp 803 is fixedly connected to the lower end of the rubber shell 801.

[0048] When installing the main body 9 of the hanging plate, the cooperation of the lighting unit 8 and the photosensitive unit 604 can be used for auxiliary positioning work. As Figure 11 shown, before installing the main body 9 of the hanging plate, the lighting unit 8 is fixed at the preset ceiling frame positioning position by the fixing nail 802. During the installation process of the main body 9 of the hanging plate, the lighting unit 8 needs to be directly facing the photosensitive unit 604 to complete the positioning work. Otherwise, an alarm is issued to remind the ceiling worker to make fine adjustments, or the control terminal with a preset program in the moving base 1 and the rotating unit 3 is used to make fine adjustments to the position of the moving base 1 or the rotating position of the support shaft 4 according to the light intensity detected by the photosensitive unit 604 to achieve automatic positioning work. At the same time, when the main body 9 of the hanging plate is installed and fixed, the support bar 6 contacts and adsorbs the lighting unit 8. During the subsequent descent of the hydraulic rod 2, the lighting unit 8 will be pulled out of the ceiling frame to complete the recycling work.

[0049] Specifically, the prerequisite for the normal use of the auxiliary positioning module in this embodiment is that the main body 9 of the hanging plate does not cover the photosensitive unit 604. When the area of the main body 9 of the hanging plate is too large to cover the photosensitive unit 604, the ceiling worker needs to perform the positioning work by himself.

[0050] In this embodiment, the auxiliary positioning work is realized by adding the photosensitive unit 604 and the lighting unit 8, greatly reducing the operation difficulty of the manipulator for ceiling decoration construction and improving the usability of the equipment.

[0051] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
