Description

Technical Field

[0001] The present invention relates to a flipping device, and particularly to a flipping mechanism for narrow spaces. Background Art

[0002] A flipping mechanism generally mainly consists of a transmission device and a flipping device. The transmission device usually adopts components such as a motor, a reducer, and a connecting rod, etc., which are used to provide power and control the speed and strength of flipping. The flipping device includes a flipping tabletop, guide rails, and fixing devices, which are used to support and fix the object to be flipped. The flipping mechanism first places the object to be flipped on the flipping tabletop and fixes it through the fixing device to ensure stability during the flipping process. Then the transmission device transmits power to the flipping device. The motor provides sufficient torque through the reducer, and the connecting rod drives the flipping tabletop to rotate along the guide rails. As the flipping tabletop rotates, the object to be flipped also rotates accordingly. By controlling the speed and strength of the transmission device, flipping at different angles can be achieved. After the object to be flipped reaches the target angle, the transmission device stops working and the flipping tabletop stops rotating. Flipping mechanisms are often applied in automated production lines, logistics warehousing, product inspection and packaging, and mechanical assembly. Currently, the existing flipping mechanisms have complex structures, poor working stability, and cumbersome operations, and it is very difficult to adapt to the flipping operations in small working spaces.

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] As Figures 1 to 4 shown, the present invention provides a flipping mechanism for a narrow space, including a linear drive module, a connecting rod assembly, a support plate 10 and a rotating plate 25. One end of the rotating plate 25 is rotatably connected to the support plate 10. The linear drive module is arranged on the support plate 10, and the output end is connected to the rotating plate 25 through the connecting rod assembly. The linear drive module drives the rotating plate 25 to flip through the connecting rod assembly.

[0021] As Figures 1 to 3 shown, in an embodiment of the present invention, the linear drive module includes a gear transmission mechanism, a motor 3, a bearing housing 5, a lead screw nut 7, a rotating shaft 8, a lead screw 11 and a lead screw connecting frame 12. The bearing housing 5 is connected to the support plate 10. The rotating shaft 8 is of a hollow structure and is rotatably installed on the bearing housing 5. The lead screw nut 7 is coaxially connected to the rotating shaft 8. One end of the lead screw 11 penetrates through the lead screw nut 7 and the rotating shaft 8, and the lead screw 11 is threadedly connected to the lead screw nut 7. The other end of the lead screw 11 is slidably connected to the support plate 10 through the lead screw connecting frame 12. The motor 3 is arranged on the support plate 10, and the output end is connected to the lead screw nut 7 through the gear transmission mechanism. The motor 3 drives the lead screw nut 7 to rotate through the gear transmission mechanism, thereby driving the lead screw 11 to perform a linear motion along the axial direction.

[0022] As Figure 2 shown, in an embodiment of the present invention, the gear transmission mechanism includes a lead screw nut gear 1 and a motor gear 2. The lead screw nut gear 1 is fixedly arranged on the lead screw nut 7, and the motor gear 2 is arranged at the output end of the motor 3 and meshes with the lead screw nut gear 1.

[0023] Specifically, as Figure 4 shown, a transition plate 9 is connected to the end of the support plate 10. The bearing housing 5 is arranged on the transition plate 9. The rotating shaft 8 is connected to the bearing housing 5 through a bearing 6. The end of the bearing 6 is limited and fixed by a lock nut 4.

[0024] As Figure 1 、 Figure 3As shown in the figure, in the embodiment of the present invention, the connecting rod assembly includes a lower sliding bracket 23, a pull rod 21, a connecting rod A 18 and a connecting rod B 19. Among them, the lower sliding bracket 23 is connected to one end of the support plate 10. One end of the pull rod 21 is connected to the lead screw connecting frame 12, and the other end is hinged to one end of the connecting rod B 19 through a shaft B 20. The shaft B 20 is slidably connected to the lower sliding bracket 23 along the output direction of the linear drive module. The other end of the connecting rod B 19 is hinged to one end of the connecting rod A 18 through a shaft A 17. The shaft A 17 is slidably connected to the rotating plate 25. The other end of the connecting rod A 18 is hinged to the lower sliding bracket 23 through a rotating shaft 15.

[0025] Further, a chute is provided on the lower sliding bracket 23 along the output direction of the linear drive module, and the shaft B 20 is accommodated in the chute. An upper sliding bracket B 22 is provided on the rotating plate 25, and the shaft A 17 is slidably connected to the upper sliding bracket B 22.

[0026] As Figure 3 shown in the figure, in the embodiment of the present invention, the lead screw connecting frame 12 is connected to the pull rod 21 through a sliding shaft A 13 and a sliding shaft B 14 arranged in parallel. An upper sliding bracket A 16 for guiding the sliding shaft A 13 and the sliding shaft B 14 is provided on the support plate 10.

[0027] In the embodiment of the present invention, two groups of linear drive modules are symmetrically provided on the support plate 10, and the two groups of linear drive modules are respectively connected to the rotating plate 25 through two groups of connecting rod assemblies, thereby improving the stability of the rotating plate 25 during the rotation process.

[0028] The working principle of a flipping mechanism for a narrow space provided by the present invention is:

[0029] The motor 3 is installed on the transition plate 9, and the transition plate 9 is installed on the support plate 10. The motor gear 2 is installed on the output shaft of the motor 3. When the motor 3 rotates, it drives the motor gear 2 to rotate, and then drives the lead screw nut gear 1 installed on the lead screw nut 7 to rotate, so that the lead screw nut 7 rotates. Since the lead screw nut 7 is rotatably installed on the bearing block 5 through the rotating shaft 8, and the bearing block 5 is fixed on the support plate 10, the lead screw nut 7 only has the function of rotation and no moving function. When the lead screw nut 7 rotates, it drives the lead screw 11 to move linearly. The lead screw 11 is fixedly connected to the lead screw connecting frame 12 through the fixing pin 24, and the lead screw connecting frame 12 is connected to the pull rod 21 through the sliding shaft A 13 and the sliding shaft B 14 to realize the movement of the above parts. The pull rod 21 is connected to the connecting rod A 19 through the shaft B 20, and the connecting rod A 19 is connected to the connecting rod B 18 through the shaft A 17. When the pull rod 22 moves together with the lead screw 11, the shaft B 20 moves along the guide groove on the lower sliding bracket 23. The connecting rod A 19 can move along the lower sliding bracket 23 and can also rotate around the shaft B 20. The rotating shaft 15 is connected to the lower sliding bracket 23. The two ends of the connecting rod B 18 are respectively hinged to the rotating shaft 15 and the shaft A 17. The shaft A 17 can move along the guide groove on the upper sliding bracket B 22. Due to the above constraint relationship, the lead screw 11 drives the pull rod 21 to move, and the connecting rod B 19 moves along the guide groove on the lower sliding bracket 23 and the guide groove on the upper sliding bracket B 22, and rotates around the shaft B 20 and the shaft A 17 at the same time, so as to realize the rotation of the rotating plate 25.

[0030] A flipping mechanism for passing through narrow gaps provided by the present invention utilizes the principle of hybrid drive of a multi-stage linkage mechanism and can enter the space to be operated through narrow gaps. The flipping mechanism has the advantages of small size, simple control, strong load capacity, and the ability to pass through narrow gaps.

[0031] The above is only the embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, expansions, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
