[0032] In a flipping mechanism of the present application, the flipping mechanism can be divided into a mounting base 1 and a flipping assembly 5 according to its function. An adjusting groove 11 is provided on the mounting base 1, and a driving member 3 is connected to the mounting base 1. The driving member 3 can be a motor or a cylinder or other workpiece with the same function. The driving member 3 is inserted into the adjusting groove 11. A detector 12 is provided at the rotating shaft of the mounting base 1 facing the driving member 3. The detector 12 can sense the current position of the rotating shaft, and the degree of flipping can be adjusted more accurately, so that the flipping of the mechanism is more efficient. The detector 12 and the inner wall of the mounting base 1 wrapped around the driving member 3 can also play a limiting role to prevent the driving member 3 from flipping. Over-turning causes errors in the position adjustment of the incoming material. The flipping component 5 is directly driven and connected to the driving member 3, and the mounting seat 1 is provided with a bearing fixing seat 13 facing the flipping component 5, so that one end of the flipping component 5 is rotatably connected to the bearing fixing seat 13, and the other end is driven and connected to the driving member 3. The bearing fixing seat 13 can play a limiting role. The end face of the flipping component 5 away from the bearing fixing seat 13 is provided with a suction nozzle 71, and the driving member 3 and the bearing fixing seat 13 can play a clamping role. With the help of the driving member 3, the suction nozzle 71 can be rotated with the bearing fixing seat 13 as the axis, so that the material can be flipped efficiently and accurately with only a small space.

[0033] Combined with reference Figures 1 to 3 In one embodiment of the present application, the flip assembly 5 includes a rotation limit sleeve 51 and a movable seat 7.

[0034] In a flipping mechanism of the present application, the flipping mechanism is composed of a rotating limit sleeve 51 and a moving seat 7. The rotating limit sleeve 51 is provided with a rotating rod 52 facing the bearing fixing seat 13, and the moving seat 7 is provided with an adjusting rod 72 facing the adjusting block 4. With the help of the bearing fixing seat 13, the rotating rod 52, the adjusting rod 72 and the driving member 3, the movement range of the entire flipping mechanism can be limited to the space enclosed by the mounting seat 1 and the detector 12, which can effectively reduce its occupied space.

The end of the rotating limit sleeve 51 away from the rotating rod 52 and the adjusting rod 72 is penetrated by a sliding cavity 6, and the moving seat 7 is slidably connected in the sliding cavity 6, which can be driven by the driving member 3. When the suction nozzle 71 is driven to rotate around the rotating rod 52, the movable seat 7 can be partially received in the rotating limit sleeve 51, which plays a limiting role and reduces the scanning area of ​​the movable seat 7 when rotating, effectively reducing its existing space. A suction nozzle 71 is provided at the movable seat 7 away from the rotating limit sleeve 51. The driving member 3 is driven by the adjusting rod 72 to make the components sucked by the suction nozzle 71 turn smoothly. The rotating limit sleeve 51 is provided with a clearance groove 53 relative to the above-mentioned driving member 3. The adjusting rod 72 is slidably connected in the clearance groove 53, so that the adjusting rod 72 can be smoothly received in the rotating limit sleeve 51, and the clearance grooves 53 can be relatively arranged in multiple groups, so that the clearance grooves 53 can not only facilitate the accommodation of the movable seat 7, but also reduce the friction of the sliding cavity 6 on the movable seat 7, so that the operation of the mechanism is more stable and smooth, and the flipping efficiency can be effectively improved.

In the present embodiment, the moving seat 7 is a rectangular parallelepiped, and a group of inclined surfaces are cut at the corners of the rectangular parallelepiped. The sliding portion 61 is slidably connected to the moving seat 7, and its projection connects the side lengths to just surround the moving seat 7, so that the component can work smoothly. According to the projection, the first pressure relief portion 62 is connected to the side length of the sliding portion 61 and extends in a direction away from the sliding portion 61. The first pressure relief portion 6 2 and the moving seat 7 form a cavity, which can reduce the friction of the sliding cavity 6 on the moving seat 7, making the operation smoother. The first pressure-reducing part 62 is evenly arranged in multiple groups in the circumferential direction. The multiple groups of first pressure-reducing parts 62 surround the moving seat 7, which can effectively reduce the friction. The second pressure-reducing part 63 is arranged at the four corners of the sliding part 61 relative to the sliding part 61. The second pressure-reducing part 63 is also evenly arranged in multiple groups in the circumferential direction. It is arranged around the corners of the moving seat 7, which is also to reduce friction, reduce stress, and improve the turning efficiency of the equipment.
