[0035] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1 and Figure 2 The embodiment of the present application discloses a high-precision and load-bearing alignment platform, including: a base plate 10, a support member 20, a first moving assembly 30, a second moving assembly 40, a third moving assembly 50, an upper plate 60 and an abutment member 70.

[0037] The support member 20 is disposed on the bottom plate 10 and is located between the first moving assembly 30, the second moving assembly 40 and the third moving assembly 50, and is used to support the upper plate 60 via the abutment member 70 to increase the load-bearing capacity of the upper plate 60. The first moving assembly 30, the second moving assembly 40 and the third moving assembly 50 are all disposed on one side end of the bottom plate 10, the second moving assembly 40 is perpendicular to the first moving assembly 30, the third moving assembly 50 is perpendicular to the second moving assembly 40 and parallel to the first moving assembly 30, that is, the three are respectively located on three sides of the bottom plate 10 and are perpendicular to each other.

[0038] The upper plate 60 is connected to the end of the first moving assembly 30, the second moving assembly 40 and the third moving assembly 50 away from the bottom plate 10, that is, located above the bottom plate 10, and can drive the upper plate 60 to rotate a certain angle based on the horizontal movement of the first moving assembly 30, the second moving assembly 40 and the third moving assembly 50. The abutment member 70 is arranged between the support member 20 and the upper plate 60, with one side connected to the upper plate 60 and the other end abutting the support member 20.

The ball bearing 80 is accommodated on the support member 20, and the abutment member 70 abuts on the ball bearing 80, so as to realize point contact between the abutment member 70 and the support member 20, reduce the friction between the abutment member 70 and the support member 20, and ensure that the upper plate 60 can rotate at any angle based on the driving of the first moving assembly 30, the second moving assembly 40 and the third moving assembly 50. It is worth noting that the ball bearing 80 is a steel ball, and a plurality of steel balls are in point contact with the abutment member 70, which can further increase the load-bearing capacity of the upper plate 60.

[0040] In addition, in order to prevent the ball member 80 from deflecting when rolling, a fixing member 21 is further provided on the support member 20. The fixing member 21 is provided with a plurality of accommodating grooves 211 (see Figure 2 ), to accommodate and limit the ball member 80.

[0041] See also Figure 2 The first moving component 30 includes a driving motor 31, a screw rod 32, a lower driving block 33, an upper driving block 34 and a rotating member 35. The driving motor 31 is fixed on the base plate 10. One end of the screw rod 32 is connected to the driving motor 31, and the other end is connected to the lower driving block 33. The lower driving block 33 is located on the base plate 10, the upper driving block 34 is located above the lower driving block 33, and the rotating member 35 is located above the upper driving block 34.

[0042] Among them, a first sliding member 331 is arranged on the end of the lower driving block 33 close to the bottom plate 10, and a second sliding member 332 perpendicular to the first sliding member 331 is arranged on the end away from the bottom plate 10. A third sliding member 11 parallel to the first sliding member 331 is arranged on the bottom plate 10, so that the lower driving block 33 is engaged with the third sliding member 11, and moves horizontally and linearly based on the rotation of the screw rod 32 under the driving action of the driving motor 31. A fourth sliding member 341 is arranged on the end of the upper driving block 34 close to the lower driving block 33 corresponding to the second sliding block. The upper driving block 34 can engage the second sliding member 332 based on the fourth sliding member 341, and move horizontally and linearly perpendicular to the first sliding member 331, so that the lower driving block 33 and the upper driving block 34 can realize movement in two dimensions, namely, the XY axis direction. It is explained here that the first sliding member 331, the second sliding member 332, the third sliding member 11, and the fourth sliding member 341 are of the slide rail style, such as Figure 3 The above are both set to two.

[0043] The rotating member 35 is arranged at one end of the upper driving block 34 away from the lower driving block 33, that is, above the upper driving block 34, and the upper plate 60 is located at one end of the rotating member 35 away from the upper driving block 34, that is, above the rotating member 35 and is connected to the rotating member 35, so that when the upper driving block 34 moves, it cooperates with the synchronous movement of the second moving component 40 and the third moving component 50 to generate a Z-axis rotational force on the upper plate 60 to drive the upper plate 60 to rotate.

[0044] See also Figure 4 In this embodiment, the first moving assembly 30, the second moving assembly 40 and the third moving assembly 50 have the same structure and are located on three sides of the bottom plate 10 and are vertically arranged to each other. The corresponding three rotating members 35 are connected to the upper plate 60. When the upper driving block 34 moves, the upper plate 60 is driven to rotate by the three rotating members 35 to facilitate the control of the rotation angle of the upper plate 60, thereby further improving the positioning accuracy of the alignment platform.

[0045] See also Figure 2 The alignment platform also includes a connecting block 90 and a first sensing component 100. The connecting block 90 is sleeved on the screw rod 32 and moves linearly as the driving motor 31 drives the screw rod 32 to rotate. The connecting block 90 is located between the driving motor 31 and the lower driving block 33 and is used to connect the lower driving block 33 to move linearly together with the rotation of the screw rod 32. The first sensing component 100 includes a first sensing member 101 and a first slot sensor 102. The first sensing member 101 is arranged on the side of the connecting block 90 and is used to move with the connecting block 90. ​​The first slot sensor 102 is arranged on the side of the bottom plate 10 and is used to sense the first sensing member 101 in real time, so as to realize real-time sensing of the movement origin and the left and right limit positions of the first moving component 30.

[0046] See also Figure 4 A second sensing component 110 and a third sensing component 120 are respectively provided on the alignment platform corresponding to the second moving component 40 and the third moving component 50 .

[0047] The second sensing component 110 includes a second sensing member and a second slot sensor. The second sensing member is disposed on the second moving component 40. The second slot sensor corresponds to the second sensing member and is disposed on the side of the bottom plate 10 to sense the second sensing member. Thus, the second sensing component 110 can sense the movement origin and the left and right limit positions of the second moving component 40 in real time.

[0048] The third sensing component 120 includes a third sensing element and a third slot-type sensor. The third sensing element is arranged on the third movable component 50. The third slot-type sensor corresponds to the third sensing element and is arranged on the side of the base plate 10 for sensing the third sensing element. In this way, the third sensing component 120 can perform real-time sensing of the movement origin and the left and right limit positions of the third movable component 50.

[0049] In this way, based on the first sensing component 100, the second sensing component 110, and the third sensing component 120, the real-time sensing of the motion origin and the left and right limit positions of the first moving component 30, the second moving component 40, and the third moving component 50 are respectively performed, which can facilitate the precise control of the rotation angle of the upper plate 60 to further improve the positioning accuracy of the alignment platform.

[0050] In summary, the embodiment of the present application discloses a high-precision and load-bearing alignment platform, in which a first movable assembly 30, a second movable assembly 40 and a third movable assembly 50 that are perpendicular to each other are arranged on the three side surfaces of the base plate 10, and can drive the upper plate 60 to rotate by a certain angle together during synchronous movement, so as to control the rotation angle of the upper plate 60, thereby improving the positioning accuracy of the alignment platform; a support member 20 is arranged on the base plate 10, and is located between the first movable assembly 30, the second movable assembly 40 and the third movable assembly 50, so as to play a supporting role when the upper plate 60 is load-bearing, and to avoid deformation of the upper plate 60 when bearing load, thereby improving the load-bearing capacity of the upper plate 60, and thus the present application can simultaneously improve the positioning accuracy and load-bearing capacity of the alignment platform.
