Description

Technical Field

[0001] The utility model relates to the technical field of hospital bed assembly production lines, and particularly relates to a lifting and flipping assembly line for hospital beds. Background Art

[0002] In the manufacturing process of medical equipment, the assembly of hospital beds is a complex and delicate process, involving the precise combination and installation of multiple components. Most traditional assembly line designs are aimed at the assembly of a single surface or specific components, lacking flexibility and versatility, and are difficult to meet the assembly requirements of hospital bed components from multiple angles and sides. During the assembly process, workers need to frequently manually flip the hospital bed components. This step not only has a great labor intensity, easily causes worker fatigue and misoperation, but also severely restricts the improvement of assembly efficiency. In addition, traditional assembly lines have obvious deficiencies in height adjustment and cannot be flexibly adjusted according to the height of operators or the operating requirements of robotic arms. Content of the Utility Model

[0003] The purpose of the utility model is to provide a lifting and flipping assembly line for hospital beds, which integrates the functions of lifting, flipping and locking, can realize the rapid, accurate and automatic assembly of hospital bed components, improve production efficiency and reduce labor intensity.

[0004] To achieve the above object, the solution of the utility model is: a lifting and flipping assembly line for hospital beds, including at least one mobile rack; a horizontal operation frame for carrying hospital bed components is arranged on the mobile rack, and a lifting mechanism for controlling the lifting of the horizontal operation frame is also arranged on the mobile rack;

[0005] The lifting mechanism includes a lifting platform and a driving component for driving the lifting platform to move up and down. A rotating shaft is fixedly connected to the horizontal operation frame, and the rotating shaft is rotatably connected to the lifting platform. The horizontal operation frame moves up and down following the movement of the lifting platform. In addition, when the horizontal operation frame is acted on by an external force, it drives the rotating shaft to rotate. A locking mechanism is arranged on the rotation path of the rotating shaft, and the locking mechanism is used to lock the rotating shaft to restrict its rotation, or unlock the rotating shaft to make it rotate freely.

[0006] Further, the lifting mechanism includes a lead screw, a nut and a lifting platform. The lead screw is fixed on the mobile rack and is driven by a motor to rotate forward and backward. The forward and backward rotation of the lead screw drives the nut on it to move up and down. The lifting platform is fixedly connected to the nut and moves up and down following the movement of the nut; the lifting platform moves up and down, driving the horizontal operation frame connected to it to move up and down.

[0007] Further, guiding mechanisms are arranged on both sides of the lifting mechanism of the mobile rack. Each group of guiding mechanisms includes a guiding column and a guiding slider. The guiding column is vertically fixed on the mobile rack, the guiding slider is slidably arranged along the length direction of the guiding column, and the lifting platform is fixedly connected to the guiding slider.

[0008] Further, the locking mechanism includes a fixed seat and a bolt. The fixed seat is fixedly connected to the lifting platform. A channel is formed in the fixed seat and penetrates through to the surface of the rotating shaft. The bolt is movably arranged in this channel.

[0009] A socket coaxial with the bolt is formed in the rotating shaft. When the bolt moves downward and inserts into the socket, the rotation of the rotating shaft is restricted. When the bolt moves upward and disengages from the socket, the rotating shaft is unlocked.

[0010] Further, a bolt seat is vertically arranged on the fixed seat. A limiting cavity communicating with and coaxial with the channel of the fixed seat is formed in the bolt seat. The bolt is movably arranged in the limiting cavity. A limiting step is radially formed inwardly on the inner side wall of the limiting cavity to prevent the bolt from disengaging from the fixed seat from above.

[0011] Further, the number of sockets on the rotating shaft is at least two. These two sockets are coaxial, and the axis is vertically perpendicular to the operating plane of the horizontal operating table.

[0012] Further, the rotating shaft is rotatably arranged on the lifting platform through a plurality of ball bearings.

[0013] Further, a set of the lifting mechanisms is respectively arranged on the left and right sides of the moving frame. The two sets of lifting mechanisms are symmetrically distributed on the moving frame.

[0014] Further, a pulley assembly is arranged at the bottom of the moving frame. The pulley assembly cooperates with the track to enable the moving frame to move along the track.

[0015] Further, moving wheels are arranged at the bottom of the moving frame.

[0016] After adopting the above scheme, the beneficial effects of the present utility model are as follows:

[0017] For the horizontal operating table on each moving frame of the bed lifting and flipping assembly line of the present utility model, a lifting mechanism is provided to realize flexible adjustment of the height of the horizontal operating table. This design not only adapts to the height requirements of different operators but also optimizes the working space of the manipulator, ensuring the smooth progress of the assembly operation.

[0018] A rotating shaft is fixedly connected to the horizontal operating frame. The rotating shaft is rotatably connected to the lifting platform. In this way, when it is necessary to flip the horizontal operating frame, only a certain force needs to be applied to the side of the horizontal operating frame, and the horizontal operating frame will drive the rotating shaft to rotate relative to the lifting platform to achieve flipping. After flipping in place, the rotating shaft can be locked by the locking mechanism, effectively preventing accidental rotation of the horizontal operating frame during the assembly process and ensuring the accuracy and stability of the assembly.

[0019] This semi-automatic flipping and automatic lifting mechanism replaces the traditional manual flipping operation, effectively reducing the physical labor burden of workers and significantly improving the production efficiency of the production line. Brief Description of the Drawings

[0032] The following is a detailed description of the present utility model with reference to the accompanying drawings and specific embodiments.

[0033] The present utility model provides a hospital bed lifting and flipping assembly line, as Figures 1 to 6 shown, which includes at least one mobile rack 1. A horizontal operation frame 2 for carrying the hospital bed assembly 9 to be assembled is provided on the mobile rack 1. After the hospital bed assembly 9 to be assembled is fixed on the horizontal operation frame 2, the operator can perform assembly operations on it.

[0034] To accommodate operators or manipulators of different heights, a lifting mechanism 3 for controlling the lifting of the horizontal operating frame 2 is also provided on the moving rack 1, which facilitates the height adjustment of the horizontal operating frame 2 and improves adaptability. As Figures 2 to 4 shown, the lifting mechanism 3 shown in the present utility model is a screw rod 31 and motor 32 type lifting mechanism 3, which specifically includes a screw rod 31, a nut 33 and a lifting platform 34. The screw rod 31 is vertically fixed on the moving rack 1 and is driven by the motor 32 to rotate forward and backward. The forward and backward rotation of the screw rod 31 drives the nut 33 thereon to move up and down. And the lifting platform 34 is fixedly connected to the nut 33. Therefore, when the motor 32 drives the screw rod 31 to rotate forward and backward, the lifting platform 34 moves up and down following the movement of the nut 33, driving the horizontal operating frame 2 connected thereto to move up and down to complete the lifting action.

[0035] A set of lifting mechanisms 3 are provided on the left and right sides of the moving rack 1 respectively, and the two sets of lifting mechanisms 3 are symmetrically distributed on the moving rack 1. In this way, when carrying the hospital bed assembly 9, the left and right forces are evenly distributed, and the stability is higher.

[0036] As Figure 2 and Figure 3 shown, guiding mechanisms 4 are also provided on both sides of the lifting mechanism 3 in this solution. Each set of guiding mechanisms 4 includes a guiding column 41 and a guiding slider 42. The guiding column 41 is vertically fixed on the moving rack 1, and the guiding slider 42 is slidably arranged along the length direction of the guiding column 41. The lifting platform 34 is fixedly connected to the guiding slider 42 while being connected to the nut 33. In this way, when the lifting platform 34 moves up and down, it can drive the guiding slider 42 to move up and down along the guiding column 41, effectively preventing the deviation of the lifting platform 34.

[0037] When assembling the hospital bed assembly 9, assembly operations need to be performed on both the front and back sides, such as assembling the bed board on the front side and the legs on the back side. The traditional method of manually removing the hospital bed assembly 9, flipping it over and then placing it on the operating frame again is time-consuming and laborious, which is not conducive to improving production efficiency. Therefore, this solution designs a flipping mechanism to facilitate the rapid automatic flipping of the hospital bed assembly 9 on the production line, saving time and effort. The specific structure is, as Figures 3 to 6 shown, a rotating shaft 5 is fixedly connected to the middle of the horizontal operating frame 2, and the rotating shaft 5 is rotatably connected to the lifting platform 34 through a plurality of ball bearings 8. When flipping is required, only an external force needs to be applied to one side edge of the horizontal operating frame 2, and the horizontal operating frame 2 can drive the rotating shaft 5 to rotate, that is, rotate relative to the lifting platform 34. If no external force is applied, the rotating shaft 5 will not rotate automatically.

[0038] When the horizontal operating frame 2 needs to be locked in place for assembly operations after flipping, the locking mechanism 6 needs to be used to restrict the rotation of the horizontal operating frame 2 so that the assembly of the hospital bed assembly 9 can proceed smoothly. The locking mechanism 6 of this solution is arranged on the rotation path of the rotating shaft 5, as Figures 3 to 6As shown, the locking mechanism 6 includes a fixed seat 61, a latch seat 63 and a latch 63. The fixed seat 61 is fixedly connected to the lifting table 34. A channel is provided on the fixed seat 61 that penetrates to the surface of the rotating shaft 5. The latch seat 63 is vertically arranged on the fixed seat 61. A limiting cavity 621 that communicates with the channel of the fixed seat 61 and is coaxial is provided in the latch seat 63. The latch 63 is movably arranged in the limiting cavity 621. Here, a limiting step 622 is formed by the radial inward extension of the inner side wall of the limiting cavity 621, which is used to prevent the latch 63 from detaching from the fixed seat 61 from above. Correspondingly, a jack 64 coaxial with the latch 63 is provided on the rotating shaft 5. When it is necessary to lock the rotating shaft 5 to prevent the horizontal operating frame 2 from rotating, the latch 63 is moved downward and inserted into the jack 64, and the rotating shaft 5 cannot rotate; when it is necessary to unlock the rotating shaft 5, the latch 63 is moved upward to disengage from the jack 64, and the rotating shaft 5 and the horizontal operating frame 2 can rotate freely.

[0039] In this embodiment, as Figure 5 shown, at least two jacks 64 are provided on the rotating shaft 5. These two jacks 64 are coaxial, and the axis is vertically perpendicular to the operating plane of the horizontal operating frame 2, that is, these two jacks 64 respectively correspond to the front and back of the horizontal operating frame 2. When the latch 63 is inserted into the jack 64 on the front side, the front side of the horizontal operating frame 2 faces upward, and when the latch 63 is inserted into the jack 64 on the back side, the back side of the horizontal operating frame 2 faces upward. Of course, the number of jacks 64 on the rotating shaft 5 can also be more to meet the positioning of the horizontal operating frame 2 at different angles.

[0040] Since the mobile rack 1 has both lifting and flipping functions, all the assembly operations of the hospital bed assembly 9 can be completed on one mobile rack 1. However, to improve production efficiency, multiple mobile racks 1 can be deployed simultaneously. As Figure 1 shown, each mobile rack 1 focuses on one installation stage, thus forming a more efficient assembly line production system.

[0041] As Figure 1 and Figure 2 shown, the bottom of the mobile rack 1 described in this case is equipped with mobile wheels 11, so that each mobile rack 1 can be equivalent to an intelligent forklift and can be electrically driven to move freely in an environment without a preset track 7, flexibly meeting the requirements of a changing working environment. In addition, the bottom of the mobile rack 1 is also equipped with a pulley assembly 12. The pulley assembly 12 cooperates with the preset track 7 and moves smoothly along the established route to achieve accurate positioning and efficient transportation.

[0042] To further improve the automation level, the mobile rack 1 can be connected to the control center of the overall production line. Through the unified scheduling and instructions of the control center, the mobile rack 1 can automatically and accurately move to the designated position, perform assembly tasks or carry out material transfer, greatly improving the flexibility and response speed of the production line.

With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model.
