[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] The terms "including" and "having" and any variations thereof in the specification and claims of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0032] An embodiment of the utility model provides a horizontal rotating platform, including a platform body, a driving assembly and an auxiliary limiting assembly; the platform body is used to carry products, the driving assembly is used to drive the platform body to rotate forward or reversely, and the auxiliary limiting assembly is used to limit the position of the platform body to ensure the smooth operation of the platform body.

[0033] The following is a detailed description of the components of the horizontal rotating platform provided in the embodiment of the utility model, as well as the positional relationship and connection relationship between the components, in conjunction with the accompanying drawings.

[0034] like Figures 1 to 4 As shown, the platform body 10 includes a bearing surface 11 and a connecting surface 12, and the driving assembly 20 includes a rotating shaft 21, which is connected to the connecting surface 12 and is used to drive the platform body 10 to rotate, and the bearing surface 11 is used to carry products; for example, a product clamping position is set on the bearing surface 11, and the product is fixed to the bearing surface 11 through the clamping position.

[0035] For example, the driving assembly 20 includes a motor 22 and a reducer 23, the motor 22 is connected to the reducer 23, the reducer 23 includes a rotating shaft 21, and the rotating shaft 21 is connected to the connecting surface 12 through a flexible coupling 24. The axis of the rotating shaft 21 is vertically connected to the center of the platform body 10, and the motor 22 drives the reducer 23 to rotate after rotating, and the reducer 23 drives the platform body 10 to rotate at a set speed; for example, the motor 22 is a servo motor, and the rotation speed of the platform body 10 can be adjusted by adjusting the rotation speed of the motor 22.

[0036] The rotating shaft 21 is connected to the platform body 10 through the flexible coupling 24. When the rotating shaft 21 starts to rotate, the flexible coupling 24 can absorb the instantaneous torque of the rotating shaft 21, so as to prevent the rotating shaft 21 and the structure connected thereto from being subjected to a large force at the moment of starting, thereby playing a protective role. For example, the flexible coupling 24 is connected to the rotating shaft 21 through a pin key, and the connection method is simple, fast, safe and reliable.

[0037] Continue to refer Figures 1 to 4As shown, in the embodiment of the utility model, the auxiliary limiting assembly 30 includes a rotating member 31, which is in contact with the platform body 10 and is used to rotate synchronously with the platform body 10. The rotating member 31 limits the platform body 10, that is, the platform body 10 is limited to rotate within a specified space range by the rotating member 31, and the platform body 10 can maintain horizontal rotation within the space range. Among them, since the platform body 10 needs to rotate continuously when in use, the auxiliary limiting assembly 30 is set as the rotating member 31, which can rotate synchronously with the platform body 10 when it plays a limiting role, so as not to affect the normal use of the platform body 10.

[0038] In the embodiment of the utility model, the horizontal cross section of the platform body 10 is circular; the rotating member 31 is arranged at the side end of the platform body 10 and abuts against the peripheral surface of the platform body 10. For example, the rotating member 31 includes a roller 311, the axis of the roller 311 is arranged perpendicular to the surface where the platform body 10 is located, and the peripheral surface of the roller 311 abuts against the peripheral surface of the platform body 10. The position of the roller 311 defines the horizontal activity space of the platform body 10, and the horizontal direction is the extension direction of the plane where the platform body 10 is located.

[0039] For example, the rotating member 31 includes at least two rollers 311, and the plurality of rollers 311 are evenly distributed on the circumference of the platform body 10. As shown in the figure, the two rollers 311 are on the same straight line, and are symmetrically arranged with the center of the platform body 10 as the center. For example, the two ends of the roller 311 shaft are respectively connected to ear plates, the ear plates are connected to the mounting plate, and the mounting plate is fixedly connected at a specified position. After the mounting plate determines the position of the roller 311, the position of the platform body 10 can be limited by the roller 311.

[0040] For example, the roller 311 includes a first annular protrusion 312 and a second annular protrusion 313 at both ends, and the diameters of the first annular protrusion 312 and the second annular protrusion 313 are larger than the diameter of the roller 311; and the first annular protrusion 312 is in contact with the edge of the bearing surface 11, and the second annular protrusion 313 is in contact with the edge of the connecting surface 12. The platform body 10 is further limited by the first annular protrusion 312 and the second annular protrusion 313, that is, the platform body 10 is limited in a direction perpendicular to the surface where the platform body 10 is located by the first annular protrusion 312 and the second annular protrusion 313.

[0041] In the embodiment of the utility model, the rotating member 31 is arranged at the bottom of the platform body 10 and abuts against the connecting surface 12 of the platform body 10. For example, the rotating member 31 includes a ball 321 and a bearing seat 322. The ball 321 is arranged on the bearing seat 322 and is used to rotate freely on the bearing seat 322; the top of the ball 321 abuts against the connecting surface 12 of the platform body 10. For example, the bearing seat 322 is a bull's horn bearing, and the ball 321 rotates freely on the bearing seat 322.

[0042] For example, the rotating member 31 includes at least three groups of balls 321 and bearing seats 322; multiple groups of balls 321 and bearing seats 322 form a support plane. The rotating member 31 is arranged at the bottom of the platform body 10, which forms a horizontal support surface, and the platform body 10 rotates on the support surface, which is conducive to keeping the platform body 10 in a horizontal state.

[0043] Continue to refer Figures 1 to 4 As shown, in the embodiment of the utility model, the horizontal rotating platform also includes a bracket 40, on which a supporting table 41 is provided. The supporting table 41 is located on the side where the connecting surface 12 is located, and the rotating shaft 21 passes through the supporting table 41 and is connected to the platform body 10; the rotating member 31 is provided on the supporting table 41.

[0044] For example, the bracket 40 includes multiple legs, and the driving assembly 20 is located between the legs. The driving assembly 20 can be fixed by a fixed structure to ensure that the position of the driving assembly 20 is fixed to avoid affecting the rotation of the platform body 10. For example, the fixing frame is fixedly connected to the legs.

[0045] The embodiment of the utility model also provides a 3D scanning device, including the above-mentioned horizontal rotating platform. The product to be scanned is placed on the horizontal rotating platform, the position of the scanner can be fixed or rotated, and the product rotates smoothly on the horizontal rotating platform to obtain more accurate scanning information.

[0046] The embodiment of the utility model provides a horizontal rotating platform and 3D scanning equipment. When in use, the driving assembly 20 drives the platform body 10 to rotate forward or reverse. During the rotation of the platform body 10, the rotating member 31 of the auxiliary limiting assembly 30 is used to limit the platform body 10, so that the platform body 10 is limited to rotate within a set space. The technical solution of the utility model uses the auxiliary limiting assembly 30 to limit the position of the platform body 10, ensuring that the platform body 10 rotates within a certain spatial range, and the platform body 10 can maintain horizontal rotation within the spatial range to ensure that the platform body 10 runs smoothly and reliably.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
