Description

Technical Field

[0001] The utility model relates to the technical field related to sofa production, in particular to an iron frame lifting and flipping mechanism. Background Art

[0002] In the modern sofa manufacturing process, the assembly line has become an important tool for improving production efficiency. Among them, the iron frame is the main support structure of the sofa, and the accuracy and efficiency of its transportation and assembly directly affect the quality and cost of the final product. However, in the prior art, when the bottom surface of the sofa iron frame on the conveying mechanism faces downward, if a three-axis manipulator is directly used for grasping and transporting, many difficulties will be faced. First of all, the manipulator needs to accurately identify and grasp the bottom of the iron frame, which is difficult to achieve when the bottom surface of the iron frame faces downward; secondly, even if the manipulator can grasp the iron frame, due to the action of gravity, instability may occur during the flipping process, resulting in damage to the iron frame or shutdown of the assembly line. Summary of the Utility Model

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides an iron frame lifting and flipping mechanism. It can solve the problem of unstable grasping caused by the manipulator's inability to grasp the bottom of the iron frame. The iron frame is flipped and lifted to a certain height through the mechanism of this application, which is beneficial for the manipulator to grasp.

[0004] The technical solution adopted by the utility model to solve its problems is as follows:

[0005] An iron frame lifting and flipping mechanism includes symmetrically arranged first lifting and flipping equipment and second lifting and flipping equipment. Both the first lifting and flipping equipment and the second lifting and flipping equipment include: a bracket; a lifting mechanism, the lifting mechanism is assembled on the bracket, the lifting mechanism includes a lifting driving device arranged vertically along the bracket, the lifting driving device includes an output end and a slider, and the output end drives the slider to make a linear reciprocating motion in the vertical direction; a flipping mechanism, a turntable is arranged on the flipping mechanism, and the flipping mechanism is connected to the moving end of the lifting driving device; a clamping mechanism, the clamping mechanism is assembled on the flipping mechanism and rotates following the turntable of the flipping mechanism.

[0006] By adopting the above scheme, a modular design is adopted. Each lifting and flipping equipment includes a bracket, a lifting mechanism, a flipping mechanism and a clamping mechanism, which can respectively fix both ends of the iron frame, realize the automatic lifting and flipping of the iron frame, and the whole process is automatically controlled by the control system without too much manual intervention, significantly improving the operation convenience.

[0007] Further, the bracket includes: a vertical rod; a first assembly plate mounted at the top end of the vertical rod; a second assembly plate mounted at the bottom end of the vertical rod; a guide rod assembled between the first assembly plate and the second assembly plate, and the guide rod passes through the slider so that the moving end of the lifting drive device drives the slider to move along the guide rod.

[0008] By adopting the above solution, the vertical rod, as the main part of the bracket, provides the vertical support force required by the entire lifting and flipping mechanism. The guide rod is assembled between the first assembly plate and the second assembly plate, providing precise guidance for the linear movement of the slider. Through precise guidance and stable support, the stability and safety of the iron frame during the lifting and flipping processes are ensured. This design not only improves the working efficiency of the mechanism but also extends the service life of the equipment and reduces the maintenance cost.

[0009] Further, the lifting drive device is a lifting cylinder, the output end is the piston rod of the lifting cylinder, and the piston rod is fixedly connected to the slider; or, the lifting drive device is a screw motor, the output end is a screw, and the screw is rotatably connected to the slider.

[0010] By adopting the above solution, the lifting cylinder drives the piston rod to perform linear movement through air pressure or hydraulic pressure. When gas or liquid is filled into the cylinder, the piston rod will extend outwards, driving the slider fixedly connected thereto to rise; conversely, when the gas or liquid is discharged, the piston rod will retract and the slider will descend. The lifting cylinder responds quickly and has a large load-bearing capacity; the screw motor is a device that converts rotational motion into linear motion. The output shaft of the motor is directly connected to the screw. When the motor rotates, the screw will drive the slider rotatably connected thereto to move along the axial direction of the screw. The screw motor has high precision and stability.

[0011] Further, the flipping mechanism includes: a motor base fixedly connected to the slider; a rotating motor disposed on the motor base, the rotating motor having a turntable output shaft, and the turntable output shaft is connected to the turntable to drive the turntable to rotate.

[0012] By adopting the above solution, the flipping mechanism realizes the flipping action of the iron frame through the close cooperation of the motor base, the rotating motor and the turntable.

[0013] Further, the clamping mechanism includes: a connecting plate fixedly connected to the turntable; a clamping bottom plate vertically connected to the connecting plate; a clamping mechanism assembled on the clamping bottom plate, and the clamping mechanism is used for clamping the iron frame.

[0014] By adopting the above solution, the connecting plate should have sufficient strength and stiffness to bear the weight of the clamping mechanism and the iron frame, as well as the forces and torques generated during the flipping process. The clamping bottom plate is the supporting platform of the clamping mechanism and is perpendicularly connected to the connecting plate. It provides the basis for the installation of the clamping mechanism and ensures the stability of the clamping mechanism during operation.

[0015] Further, the clamping mechanism includes: a longitudinal clamping device, which includes a longitudinal driving member and a longitudinal clamping member, and the longitudinal driving member drives the longitudinal clamping member to move vertically; a horizontal clamping device, which includes a horizontal driving member and a horizontal clamping member, and the horizontal driving member drives the horizontal clamping member to move horizontally.

[0016] By adopting the above solution, multi-directional and multi-level clamping of the iron frame can be achieved. This design not only improves the firmness and stability of clamping, but also enhances the adaptability of the clamping mechanism to iron frames of different sizes and shapes. In practical applications, the positions and clamping forces of the longitudinal clamping member and the horizontal clamping member can be adjusted according to the specific size and shape of the iron frame to achieve the best clamping effect.

[0017] Further, a slide rail is provided on the clamping bottom plate, the horizontal clamping member slides along the slide rail, and the horizontal driving member is assembled on the clamping bottom plate.

[0018] By adopting the above solution, the slide rail provides precise guidance for the horizontal clamping member, ensuring that its moving trajectory in the horizontal direction is straight and stable. This helps to reduce the risk of unstable clamping or damage to the iron frame caused by the shaking or deviation of the clamping member.

[0019] Further, the longitudinal driving member is assembled on the horizontal driving member, and the longitudinal clamping member extends along the edge direction of the turntable, so that a clamping space is formed by enclosing between the longitudinal clamping member, the turntable, the clamping bottom plate and the longitudinal driving member.

[0020] By adopting the above solution, the clamping space provides a stable clamping environment for the iron frame. In this space, the iron frame can be firmly clamped and maintain a stable posture during the flipping process.

[0021] Further, triangular ribs are provided between the clamping bottom plate and the connecting plate.

[0022] By adopting the above solution, the connection strength between the clamping bottom plate and the connecting plate can be significantly enhanced. Due to the excellent stability of the triangle, the addition of the triangular ribs can effectively resist deformation under external forces, thus ensuring the overall stability of the clamping mechanism.

[0023] Further, an auxiliary fixing device is provided between the slider and the motor base. The auxiliary fixing device includes a base support and a limit enclosure fixedly connected to the slider. A limit space is formed between the base support and the limit enclosure, and the motor base is limited within the limit space.

[0024] By adopting the above solution, the base support is fixedly connected to the slider and serves as the basic support surface of the motor base. It bears the weight of the motor base and its components thereon and transfers it to the slider, which is finally borne by the lifting mechanism, ensuring that there is no deformation or damage when the motor base and its components are working; the limit enclosure is connected to the base support to form a limit space surrounding the motor base. This space limits the movement range of the motor base in the horizontal and vertical directions, preventing it from deviating from the predetermined position due to vibration or external forces during operation, and ensuring that the limit space can effectively limit the movement of the motor base without interfering with its normal operation.

[0025] In summary, a steel frame lifting and flipping mechanism provided by the present utility model has the following technical effects:

[0026] 1. Through automatic control, the lifting and flipping actions of the steel frame can be quickly completed, reducing the time and labor intensity of manual operation, thereby significantly improving the production efficiency in the sofa manufacturing process.

[0027] 2. Improve the grasping stability: Since the mechanism design allows the steel frame to be flipped to a position suitable for the manipulator to grasp, such as flipping the steel frame with the bottom surface facing up to the side or the top surface facing up, the problem that the manipulator is difficult to stably grasp the steel frame with the bottom surface facing down is solved. The flipped steel frame is easier to be accurately recognized and stably grasped by the manipulator, reducing the risk of damage to the steel frame or shutdown of the production line caused by unstable grasping.

[0028] 3. The automatic lifting and flipping process reduces the need for direct human contact with the steel frame, reducing the safety hazards caused by improper human operation. At the same time, the design of the mechanism also takes into account the stability during the flipping process, avoiding the possible injuries caused by unstable flipping of the steel frame.

[0029] 4. By precisely controlling the lifting and flipping process of the steel frame, the deformation or damage of the steel frame caused by improper operation can be reduced, thereby improving the product quality of the final sofa.

[0030] 5. The mechanism adopts a modular design and can be adjusted and optimized according to steel frames of different sizes and shapes, with high adaptability and flexibility. This enables the mechanism to be widely applied in various sofa manufacturing processes to meet different production requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0041] Refer to Embodiment 1 of the present utility model Figures 1-5 As shown, a steel frame lifting and flipping mechanism is disclosed, which includes symmetrically arranged first lifting and flipping devices 1 and second lifting and flipping devices 2. The first lifting and flipping device 1 and the second lifting and flipping device 2 are respectively used to clamp both ends of the same steel frame to lift and prevent collision of the steel frame. Specifically, the first lifting and flipping device 1 and the second lifting and flipping device 2 both include a bracket 3, a lifting mechanism 4, a flipping mechanism 5, and a clamping mechanism 6. The lifting mechanism 4 is assembled on the bracket 3. The lifting mechanism 4 includes a lifting drive device 41 arranged vertically along the bracket 3. The lifting drive device 41 includes an output end 411 and a slider 412. The output end 411 drives the slider 412 to perform linear reciprocating motion in the vertical direction. A turntable 53 is arranged on the flipping mechanism 5. The flipping mechanism 5 is connected to the mobile end of the lifting drive device 41. The clamping mechanism 6 is assembled on the flipping mechanism 5 and rotates with the turntable 53 of the flipping mechanism 5. By adopting a modular design, each lifting and flipping device includes a bracket 3, a lifting mechanism 4, a flipping mechanism 5, and a clamping mechanism 6, which can respectively fix both ends of the steel frame, realizing the automatic lifting and flipping of the steel frame. The whole process is automatically controlled by a control system without too much manual intervention, significantly improving the operation convenience.

[0042] When the assembly line is working, the steel frame is transported through the assembly line. The first lifting and flipping device 1 and the second lifting and flipping device 2 are arranged on both sides of the assembly line. When the sofa steel frame on the assembly line reaches between the first lifting and flipping device 1 and the second lifting and flipping device 2, the clamping mechanism 6 starts to work to clamp and fix the steel frame. Then, the steel frame is lifted to the top by the lifting mechanism 4. At this time, enough flipping space is reserved between the lower part of the steel frame and the conveying mechanism. Then, the flipping mechanism 5 flips the steel frame by 180°, waiting for the manipulator to transport the steel frame to the next working station.

[0043] In the present Embodiment 1, specifically, the bracket 3 includes a vertical rod 31, a first assembly disc 32, a second assembly disc 33 and a guide rod 34. The first assembly disc 32 is installed at the top end of the vertical rod 31, and the second assembly disc 33 is installed at the bottom end of the vertical rod 31. The connection between the vertical rod 31, the first assembly disc 32 and the second assembly disc 33 includes but is not limited to integral molding, screw fixation, welding or snap connection. The guide rod 34 is assembled between the first assembly disc 32 and the second assembly disc 33. Preferably, there are two guide rods 34, which are arranged in parallel on both sides of the lifting drive device 41. The guide rod 34 passes through the slider 412 so that the moving end of the lifting drive device 41 drives the slider 412 to move along the guide rod 34. The vertical rod 31 provides the vertical support force required for the entire lifting and flipping mechanism 5. The guide rod 34 is assembled between the first assembly disc 32 and the second assembly disc 33, providing precise guidance for the linear movement of the slider 412. The flipping mechanism 5 includes a motor base 51 and a rotating motor 52. The motor base 51 is vertically assembled on the side wall of the slider 412. The connection between the motor base 51 and the slider 412 includes but is not limited to welding, screw fixation or snap connection. The rotating motor 52 is arranged on the motor base 51. The rotating motor 52 has a turntable output shaft 521. The axial direction of the turntable output shaft 521 is perpendicular to the motor base 51. The turntable output shaft 521 is connected to the turntable 53, specifically by bolt fixation, to drive the turntable 53 to rotate. Through the close cooperation of the motor base 51, the rotating motor 52 and the turntable 53, the flipping mechanism 5 realizes the flipping action of the iron frame.

[0044] In the present Embodiment 1, in order to facilitate the disassembly of the entire flipping mechanism 5 and at the same time achieve a stable rotational support effect, an auxiliary fixing device 7 is provided between the slider 412 and the motor base 51. The auxiliary fixing device 7 includes a base support 71 fixedly connected to the slider 412 and a limiting enclosure 72. The base support 71 is fixed to the bottom end of the slider 412, and the limiting enclosure 72 is fixed to the front side of the motor base 51. A limiting space 73 is formed between the base support 71 and the limiting enclosure 72, and the motor base 51 is limited within the limiting space 73. When installing the motor base 51, the motor base 51 is passed through the space between the limiting enclosure 72 and the slider 412 and abuts against the base support 71. At this time, the motor base 51 is successfully limited within the limiting space 73. At this time, bolts are sequentially passed through the limiting enclosure 72 and the motor base 51 and screwed to the slider 412. In some embodiments, optionally, a convex block may be provided at the bottom of the motor base 51, and a groove may be provided on the base support 71. By inserting the convex block into the groove and manually operating to quickly tighten the screw rod 74 to limit and fix the convex block in the groove, when there is a quick tightening screw rod 74, the bolts passing through the limiting enclosure 72 can be cancelled. Of course, both can also be provided. Ensure that the motor base 51 and its upper components will not be deformed or damaged during operation, prevent the motor base 51 from deviating from the predetermined position due to vibration or external force during operation, effectively limit the movement of the motor base 51, and will not interfere with its normal operation.

[0045] Optionally, the lifting drive device 41 is a lifting cylinder, the output end 411 is the piston rod of the lifting cylinder, and the piston rod is fixedly connected to the slider 412; or, the lifting drive device 41 is a screw motor, the output end 411 is a screw rod, and the screw rod is rotatably connected to the slider 412. In the present Embodiment 1, the lifting drive device 41 is a lifting cylinder.

[0046] In some embodiments, the clamping mechanism 6 includes a connecting plate 63, a clamping bottom plate 64, and a clamping mechanism 6. The connecting plate 63 is fixedly connected to the turntable 53, specifically by screw attachment. The clamping bottom plate 64 is vertically connected to the connecting plate 63. The clamping mechanism 6 is assembled on the clamping bottom plate 64. The clamping mechanism 6 is used to clamp the iron frame and ensure the stability of the clamping mechanism 6 during operation. In the present Embodiment 1, in order to improve the connection stability between the clamping bottom plate 64 and the connecting plate 63, a triangular rib 65 is provided between the clamping bottom plate 64 and the connecting plate 63, which can significantly enhance the connection strength between the clamping bottom plate 64 and the connecting plate 63. Due to the excellent stability of the triangle, the addition of the triangular rib 65 can effectively resist deformation under external force, thereby ensuring the overall stability of the clamping mechanism 6.

[0047] Preferably, the clamping mechanism 6 includes a longitudinal clamping device 61 and a horizontal clamping device 62. The longitudinal clamping device 61 includes a longitudinal driving member 611 and a longitudinal clamping member 612. The longitudinal driving member 611 drives the longitudinal clamping member 612 to move vertically. The horizontal clamping device 62 includes a horizontal driving member 621 and a horizontal clamping member 622. The horizontal driving member 621 drives the horizontal clamping member 622 to move horizontally, enabling multi-directional and multi-level clamping of the iron rack. This design not only improves the firmness and stability of clamping but also enhances the adaptability of the clamping mechanism 6 to iron racks of different sizes and shapes. In Embodiment 1, a slide rail 641 is provided on the clamping base plate 64. The horizontal clamping member 622 slides along the slide rail 641, providing precise guidance for the horizontal clamping member 622 and ensuring that its movement trajectory in the horizontal direction is straight and stable. The horizontal driving member 621 is assembled on the clamping base plate 64, helping to reduce the risk of unstable clamping or damage to the iron rack caused by the shaking or deviation of the clamping member.

[0048] Optionally, the longitudinal driving member 611 is assembled on the horizontal driving member 621. The longitudinal clamping member 612 extends along the edge direction of the turntable 53, so that a clamping space 613 is formed by enclosing between the longitudinal clamping member 612, the turntable 53, the clamping base plate 64 and the longitudinal driving member 611. The clamping space 613 provides a stable clamping environment for the iron rack. Inside this space, the iron rack can be firmly clamped and maintain a stable posture during the flipping process. Preferably, the clamping member can also rotate relative to the driving member to open the clamping space 613, which is beneficial for the entry of the iron rack and more conducive to clamping.

[0049] When the assembly line is working, the iron frame is transported through the assembly line. The first lifting and flipping device 1 and the second lifting and flipping device 2 are arranged on both sides of the assembly line. When the sofa iron frame on the assembly line reaches between the first lifting and flipping device 1 and the second lifting and flipping device 2, the longitudinal driving member 611 raises the longitudinal clamping member 612 to the highest position, then rotates the longitudinal clamping member 612 to open the clamping space 613, and then gradually rises through the lifting mechanism 4 until part of the iron frame enters the clamping space 613. At this time, rotate the longitudinal clamping member 612 to close the clamping space 613, and then the longitudinal driving member 611 drives the longitudinal clamping member 612 to descend until the clamping space 613 is closed. Then, the horizontal driving member 621 drives the horizontal clamping member 622 to slide along the slide rail 641 until it abuts against part of the iron frame. At this time, at least four parts of the iron frame are in contact with the iron frame, achieving a stable clamping effect. Then, the iron frame is raised to the top by the lifting mechanism 4. At this time, enough flipping space is reserved between the lower part of the iron frame and the conveying mechanism. Subsequently, the rotating motor 52 of the flipping mechanism 5 drives the turntable 53 to rotate and flip the iron frame by 180°. At this time, the iron frame is supported by the flipped clamping bottom plate 64. Therefore, the longitudinal clamping device 61 and the horizontal clamping device 62 return to the original state, release the clamping of the iron frame, and wait for the manipulator to transport the iron frame to the next working station.

[0050] In summary, the iron frame lifting and flipping mechanism provided by the present utility model has the following technical effects:

[0051] 1. Through automatic control, the lifting and flipping actions of the iron frame can be completed quickly, reducing the time and labor intensity of manual operation, thereby significantly improving the production efficiency in the sofa manufacturing process.

[0052] 2. Improve the grasping stability: Since the mechanism design allows the iron frame to be flipped to a position suitable for the manipulator to grasp, such as flipping the iron frame with the bottom surface facing up to the side or the top surface facing up, it solves the problem that it is difficult for the manipulator to stably grasp the iron frame with the bottom surface facing down. The flipped iron frame is easier to be accurately recognized and stably grasped by the manipulator, reducing the risk of iron frame damage or assembly line shutdown caused by unstable grasping.

[0053] 3. The automatic lifting and flipping process reduces the need for direct human contact with the iron frame, reducing the safety hazards caused by improper human operation. At the same time, the design of the mechanism also takes into account the stability during the flipping process, avoiding the possible injuries caused by unstable flipping of the iron frame.

[0054] 4. By precisely controlling the lifting and flipping process of the iron frame, the deformation or damage of the iron frame caused by improper operation can be reduced, thereby improving the product quality of the final sofa.

[0055] 5. The mechanism adopts a modular design and can be adjusted and optimized according to iron racks of different sizes and shapes, with high adaptability and flexibility. This enables the mechanism to be widely applied in various sofa manufacturing processes to meet different production requirements.

[0056] The technical means disclosed in the solution of the present utility model are not limited to those disclosed in the above embodiments, and also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
