Description

Technical Field

[0001] The invention relates to the technical field of hanger tooling, and specifically provides a special hanger for installing modular toilet panels. Background Art

[0002] Modular bathroom is an application of modern construction technology. It adopts modular design and prefabricates various modular structures of the bathroom in the factory. It can be pre-assembled in the factory and then transported to the construction site as a whole, or it is more inclined to package and transport each component module structure to the construction site for assembly. It has the advantages of efficient production, controllable quality, cost saving, environmental protection and energy saving, easy installation and disassembly; modular bathroom is mainly composed of base, wall panels, roof panels, doors, hardware components and bathroom components.

[0003] When installing a modular bathroom, it is mainly necessary to first complete the docking and assembly of modular panels such as the base, wall panels and roof panels to form the architectural frame of the modular bathroom. When assembling a single or a small number of modular bathrooms, the assembly of the panels can be completed by multiple people, and when batch assembly is required, such as pre-assembly of a large number of panels in a factory, wall panels and roof panels generally need to be installed with the aid of lifting equipment through hoists, thereby saving manpower and improving assembly efficiency.

[0004] The wall panels and the top panels are all planar panel structures. Therefore, the existing corresponding hangers basically use suction cups to absorb and grab the panels, vertically grab the wall panels, and horizontally grab the top panels, that is, the hanger as a whole needs to be turned over and oriented. Therefore, most of the existing related hangers are directly installed on the robot arm, and the hanger needs to move by the movement of the robot arm. In the actual assembly process, the wall panels and the bottom panels, the wall panels and the wall panels, and the wall panels and the top panels need to be assembled and docked in place to avoid large splicing seams, so as to ensure the quality strength and aesthetics after assembly. However, when the panels are hoisted and assembled by the robot arm and the hanger, the splicing cannot be achieved quickly, and the assembly state needs to be observed closely by humans. Because when the hanger grabs, the panel is fixed on the end of the robot arm together with the hanger as a whole, so the position of the panel needs to be adjusted continuously by the movement of the robot arm. Therefore, the existing hanger design lacks flexibility in the assembly process of the panels, which makes it difficult to assemble and splice the panels, and affects the assembly production efficiency to a certain extent. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a special hanger for installing modular bathroom panels, which is used to solve the problems mentioned in the above background technology.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] A special hanger for installing modular bathroom panels. The special hanger provided by the present invention can be docked and installed on an existing mechanical arm. The mechanical arm can drive the special hanger to move and also drive the special hanger to flip between a horizontal state and a vertical state. When flipped to a horizontal state, it is used to hang the top plate, and when flipped to a vertical state, it is used to hang the wall panel. For the sake of uniformity of description, the specific structure of the special hanger is described below based on the horizontal state.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the special lifting device includes a lifting device frame 1, the lifting device frame 1 includes a cylindrical tailstock 11 that can be fixedly mounted on the end of the robot arm and a base plate 12 fixed to one end of the cylindrical tailstock 11 by bolts; a center reset mechanism 2 is installed in the cylindrical tailstock 11, and the center reset mechanism 2 includes a central cylinder 21 that is arranged through the cylindrical tailstock 11, and a plurality of elastic side support members 22 uniformly distributed along the circumferential direction are installed on the outer cylinder wall of the central cylinder 21; the elastic side support member 22 includes two universal joints 221, one universal joint 221 is rotatably mounted on the central cylinder 21, and the other universal joint 221 is rotatably mounted on the central cylinder 21. A universal joint 221 is rotatably mounted on the cylinder tailstock 11, and a telescopic link 222 is connected between the two universal joints 221. The telescopic link 222 includes a keyway tube 2221 fixed on one universal joint 221 and a spline rod 2222 fixed on the other universal joint 221, and one end of the spline rod 2222 is slidably mounted in the keyway tube 2221; a rotating sleeve 2223 is rotatably mounted on the keyway tube 2221, and a side branch spring 223 is hinged on the rotating sleeve 2223, and the other end of the side branch spring 223 is hinged on the center cylinder 21.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the hanger frame 1 is equipped with a mechanical gripper 3 for grabbing the plate; the mechanical gripper 3 includes a guide plate 31 fixed to the bottom end of the center cylinder 21 by bolts, and a plurality of ball joint connecting rods 32 are connected between the top end of the guide plate 31 and the bottom end of the hanger frame 1; and the plurality of ball joint connecting rods 32 are evenly distributed; the ball joint connecting rod 32 includes a rotary hinge joint 321 welded on the base plate 12 and a ball joint seat 322 welded on the guide plate 31, a ball head connecting rod 323 is connected between the rotary hinge joint 321 and the ball joint seat 322, the ball head end of the ball head connecting rod 323 is hinged on the ball joint seat 322, and the other end of the ball head connecting rod 323 is hinged on the rotary hinge joint 321.

[0029] On the one hand, the center cylinder 21 is connected to the cylinder tail stock 11 through a plurality of elastic side support members 22 distributed around it, so that under the common restriction of the plurality of elastic side support members 22, the center cylinder 21 can have a certain degree of freedom of movement in the axial direction within the restriction range, and a certain degree of freedom of movement in the radial direction within the range of 360°, and the center cylinder 21 can perform a certain degree of arbitrary tilting movement in the axial direction; but in the absence of active interference from external forces, the center cylinder 21 will be in a reset state, so that the mechanical gripper 3 connected thereto is synchronously in a reset state, and in this embodiment, when the special sling is in a horizontal state, and when the center reset mechanism 2 is reset, the center axis of the center cylinder 21 coincides with the center axis of the cylinder tail stock 11, and the center axis of the ball head connecting rod 323 is parallel to the center axis of the center cylinder 21. On the other hand, the guide plate 31 is connected to the base plate 12 through a plurality of ball-jointed links 32. Any two ball-jointed links 32, the base plate 12 and the guide plate 31 form a parallelogram structure, so that when the distance of the guide plate 31 relative to the base plate 12 changes, the base plate 12 has a freedom of movement range in any direction of 360°, and the states of all the ball-jointed links 32 change synchronously, so that the guide plate 31 always remains parallel to the base plate 12; therefore, on the basis of the range of freedom of movement provided by the center reset mechanism 2, the further restriction of the plurality of ball-jointed links 32 further limits the range of movement of the center cylinder 21 in the axial and radial directions, and at the same time locks the freedom of the axial tilt and deflection of the center cylinder 21, that is, after the center cylinder 21 moves relative to the reset state position, when the sling is flipped to the horizontal state, the center axis of the center cylinder 21 always remains vertical, and when the sling is flipped to the vertical state, the center axis of the center cylinder 21 always remains horizontal.

[0030] like Figure 2 , Figure 4 and Figure 5As shown, a gripping mechanism 33 is mounted on the guide rail 311. The gripping mechanism 33 includes two sliding beams 331 relatively slidably arranged on the guide rail plate 31, and four guide rails 311 are arranged at the bottom end of the guide rail plate 31 relative to the two sliding beams 331, and the sliding beams 331 are slidably mounted on the four corresponding guide rails 311; a plurality of pneumatic suction cups 332 are fixed on the sliding beams 331; the plurality of pneumatic suction cups 332 are evenly distributed along the length direction of the sliding beams 331, and the pneumatic suction cups 332 are existing negative pressure gripping actuators, which are connected to the negative pressure pump through an air pipe; the guide rail plate 31 is also equipped with an adjustment component 333 that drives the two sliding beams 331 to synchronously slide in the opposite direction. The adjustment assembly 333 includes a driving motor 3331 fixed to the guide plate 31 by bolts and a swing rod 3332 fixed to the output shaft of the driving motor 3331. The driving motor 3331 is located in the central cylinder 21, and the driving motor 3331 is an angle motor with a built-in locking mechanism. Both ends of the swing rod 3332 are hinged with driving connecting rods 3333, and the two driving connecting rods 3333 are hinged to the two sliding beams 331 one by one. When the hoisting operation is performed, the driving motor 3331 is started, and the swing rod 3332 drives the two sliding beams 331 to slide away from each other through the two driving connecting rods 3333, so that the two sets of pneumatic suction cups 332 are in an unfolded state to expand the overall gripping surface of the plate.

[0031] When assembling a modular bathroom, the special hoist provided by the present invention is mainly used to cooperate with manual labor to hoist the wall panels and the top panels; the hoisting of the wall panels and the top panels will be explained separately below.

[0032] After the base is arranged, multiple wall panels can be lifted and assembled one by one relative to the base. Specifically, after the wall panel is grabbed by the pneumatic suction cup 332, the hoist is further driven by the robotic arm to flip the wall panel to a vertical state, and the wall panel is adjusted to a state parallel to the wall to be installed. Subsequently, the wall panel is driven by the robotic arm to move closer to the installation wall. When it is close to the installation position, the position of the wall panel can be quickly corrected manually so that the wall panel is aligned with the actual installation position. During the manual correction process, the wall panel can move in any direction parallel to the installation wall, but can always remain parallel to the wall to be installed. Therefore, after the alignment and correction, it only needs to be moved closer without the need for multi-directional position adjustment by the robotic arm. After the assembly and docking are completed, the wall panel can be locked.

[0033] After completing the assembly of multiple wall panels, the top panel can be assembled. Specifically, after grabbing the top panel, flip it to a horizontal state and gradually descend toward the top installation surface. When approaching, the top panel can also be manually corrected to align with the actual installation position at the top of the bathroom. Then, while maintaining the alignment, just descend further, and after reaching the installation position, lock the top panel on the wall panel.

[0034] The present invention provides a special hanger for installing modular bathroom panels. Compared with traditional hangers of the same type, a mechanical gripper 3 is used as the actual grabbing execution part, and is connected to the hanger frame 1 through a central reset mechanism 2 and a plurality of ball-jointed connecting rods 32 arranged by the mechanical gripper 3, so that when the mechanical gripper 3 grabs the panel within a limited range, the panel can always be kept parallel to the panel installation surface, and can be moved in any direction parallel to the panel installation surface, so that it is convenient to manually correct the position of the panel quickly during actual installation, and on the basis of the correction, it only needs to move and align in a single direction perpendicular to the panel installation surface, thereby avoiding multi-directional and multi-dimensional angle adjustment of the panel, improving the flexibility of the hanger-assisted installation, reducing the difficulty of installation between modular bathroom panels, and improving the assembly production efficiency during large-scale assembly.
