[0037] Reference will now be made to the drawings, wherein Figures 1 to 4 As shown in Figure 1 , Figure 2 and Figure 4 , the embodiment of the present application provides a positioning platform 100, the positioning platform 100 comprises a base 10, a guide assembly 20, a first mounting plate 30, a second mounting plate 40, a linear driving device 50 and an arc driving device 60.

[0038] Exemplarily, as shown in Figure 3 and Figure 4 , the guide assembly 20 can comprise a linear guide structure 21 and an arc guide structure 22.

[0039] Wherein, the base 10 can be movably connected with the first mounting plate 30 through the linear guide structure 21, and the second mounting plate 40 can be movably connected with the first mounting plate 30 through the arc guide structure 22.

[0040] Wherein, the linear guide structure 21 can comprise a linear guide rail with a flange, so as to further improve the carrying capacity of the positioning platform 100.

[0041] Exemplarily, as shown in Figure 3 , the arc guide structure 22 can comprise a plurality of guide rail and slider groups 221 sharing a common center, the guide rail and slider group 221 can comprise an arc guide rail 2211 and a slider 2212, the arc guide rail 2211 and the slider 2212 are correspondingly arranged, one of the arc guide rail 2211 and the slider 2212 can be arranged on the first mounting plate 30, and the other one can be correspondingly arranged on the second mounting plate 40.

[0042] Exemplarily, asFigure 3 And Figure 4 As shown in

[0043] For example, the alignment platform 100 can be applied to a printing machine in a screen printing process. In order to facilitate the operation of the screen plate, as shown in Figure 1 And Figure 2 As shown in

[0044] It can be further understood that in some printing machines, pneumatic devices are needed for the operation of the screen plate. As shown in Figure 2 The user can install a gas pump on the alignment platform 100 by setting a plurality of cylinder mounting holes 41 on the second mounting plate 40, and operate the pneumatic device or the screen plate through the gas pump.

[0045] Further, the linear drive device 50 can include a linear motor, one of the stator end 51 of the linear motor and the mover end 52 of the linear motor can be connected with the first mounting plate 30, and the other can be connected with the base 10. The linear drive device 50 drives the first mounting plate 30 to move linearly along the linear guide structure 21 relative to the base 10.

[0046] It can be understood that connecting the stator end 51 of the linear motor with the base 10 and connecting the mover end 52 of the linear motor with the first mounting plate 30 can facilitate electrical wiring, improve the daily operation reliability and easy maintenance of the alignment platform 100, and save wire harness materials.

[0047] Further, as shown in Figure 4 And Figure 5 The arc drive device 60 can include a flat motor or an arc motor. One of the stator end of the arc drive device and the mover end of the arc drive device can be directly connected with the first mounting plate or connected through an adapter block 613, and the other can be directly connected with the second mounting plate.

[0048] For example, as shown in Figure 3 , Figure 4 And Figure 5As shown, multiple flat motors can be made to have a common symmetric center, or multiple arc motors can be made to have a common circular center, wherein one of the stator end 611 of the arc driving device and the mover end 612 of the arc driving device can be connected to the second mounting plate 40, and the other can be connected to the first mounting plate 30, and the arc driving device 60 can be used to drive the second mounting plate 40 to rotate along the circular arc guide structure 22, and the center of the circular arc guide structure 22 and the axis of rotation can coincide with the common symmetric center or center of the multiple arc driving devices.

[0049] It can be understood that connecting the stator end of the arc drive device 60 to the first mounting plate 30 and connecting the mover end of the arc drive device 60 to the second mounting plate 40 can facilitate electrical wiring, improve the daily operation reliability and maintainability of the alignment platform 100, and save wiring harness wires.

[0050] The arc-shaped motors may be distributed at equal angles on the arc-shaped circumference of the arc guide structure 22 .

[0051] For example, Figure 3 、 Figure 4 and Figure 5 As shown, the arc driving device 60 may include a first arc driving device 61 and a second arc driving device 62. The first arc driving device 61 and the second arc driving device 62 may be co-centric with the arc guide structure 22, and the first arc driving device 61 and the second arc driving device 62 are arranged symmetrically with respect to the center of the circle.

[0052] The first arc driving device 61 and the second arc driving device 62 may be arc motors or flat motors.

[0053] It is understandable that the use of a dual-motor solution to provide power can, on the one hand, provide more sufficient power, and on the other hand, avoid shaking and vibration caused by uneven force on the load part during operation, thereby reducing the risk of equipment damage or performance degradation.

[0054] In some embodiments, see Figure 4 ,like Figure 4 As shown, the alignment platform 100 may further include an anti-collision component 70 , and the anti-collision component 70 includes a linear anti-collision component 71 and an arc anti-collision component 72 .

[0055] Exemplarily, the linear anti-collision assembly 71 may include a first anti-collision rubber 711 and a first anti-collision seat 712, one of the first anti-collision rubber 711 and the first anti-collision seat 712 is arranged on the first mounting plate 30, and the other is correspondingly arranged on the base 10, and the first anti-collision rubber 711 is used to limit the linear motion stroke of the base 10 relative to the first mounting plate 30.

[0056] Exemplarily, the arc anti-collision assembly 72 may include a second anti-collision rubber 721 and a second anti-collision seat 722, one of the second anti-collision rubber 721 and the second anti-collision seat 722 is arranged on the first mounting plate 30, and the other is correspondingly arranged on the second mounting plate 40, for limiting the arc movement stroke of the second mounting plate 40 relative to the first mounting plate 30.

[0057] It can be understood that by setting up the anti-collision component 70, the stroke of the linear drive device 50 and the arc drive device 60 can be limited, thereby ensuring the long-term, stable and reliable operation of the alignment platform 100, and reducing the risk of damage to the components of the alignment platform 100 itself under extreme working conditions such as screen overload and software failure.

[0058] In some embodiments, see Figure 4 ,like Figure 4 As shown, the alignment platform 100 may further include a linear precision control component 80 and a linear resetting component 81 .

[0059] The linear precision control assembly 80 may include a linear scale and a first reading head.

[0060] For example, a grating scale can be selected as the linear scale and a grating scale reading head can be selected as the first reading head, or a magnetic scale can be selected as the linear scale and a magnetic scale reading head can be selected as the first reading head.

[0061] Among them, one of the linear scale and the first reading head can be set on the first mounting plate 30, and the other can be set on the base 10. The linear scale and the first reading head can be used to measure the linear motion stroke of the base 10 relative to the first mounting plate 30.

[0062] Exemplarily, the linear resetting assembly 81 may include a first photoelectric switch and a first sensor sheet.

[0063] One of the first photoelectric switch and the first sensor sheet may be disposed on the first mounting plate 30 , and the other may be disposed on the base 10 .

[0064] It is understandable that, through the linear reset component 81 and the linear precision control component 80 , feedback control can be implemented to further improve the positioning accuracy or repeatability of the linear motion of the alignment platform 100 .

[0065] In some embodiments, see Figure 4 ,like Figure 4 As shown, the alignment platform 100 may further include an arc precision control component 90 and an arc resetting component.

[0066] The arc precision control component 90 may include an arc scale and a second reading head.

[0067] The arc-shaped grating ruler can adopt a code disc type, i.e., the arc-shaped appearance, and the grating ruler is provided with an angle scale, so as to better measure the related parameters of the rotating movement of the second mounting plate 40.

[0068] For example, the arc-shaped grating ruler can be a grating ruler, and the second reading head can be a grating ruler reading head. Alternatively, the arc-shaped grating ruler can be a magnetic grating ruler, and the second reading head can be a magnetic grating ruler reading head.

[0069] For example, one of the arc-shaped grating ruler and the second reading head can be arranged on the first mounting plate 30, and the other can be correspondingly arranged on the second mounting plate 40. The arc-shaped grating ruler and the second reading head can be used to measure the arc movement stroke of the second mounting plate 40 relative to the first mounting plate 30.

[0070] The arc-shaped reset assembly can include a second photoelectric switch and a second sensing sheet.

[0071] For example, one of the second photoelectric switch and the second sensing sheet can be arranged on the first mounting plate 30, and the other can be correspondingly arranged on the second mounting plate 40.

[0072] It can be understood that, through the arc reset assembly and the arc precision control assembly, feedback control can be achieved, and the positioning precision or the repeat precision of the arc movement of the alignment platform 100 can be further improved.

[0073] In some embodiments, the other side of the first mounting plate 30 relative to the second mounting plate 40 is further provided with a load guide structure 11.

[0074] The load guide structure 11 is in the same direction as the linear guide structure 21.

[0075] It can be understood that, by arranging the load guide structure 11 in the same direction as the linear guide structure 21 on the first mounting plate 30, the alignment platform 100 can be movably connected to other pressure-bearing equipment or pressure-bearing positions, so as to further improve the load-bearing capacity of the alignment platform 100 without affecting normal use.

[0076] The present application also provides a printing machine, which can include the alignment platform 100 according to any embodiment of the present application.

[0077] For example, the printing machine can be a circuit printing machine based on a screen printing process, and the screen plate of the printing machine can be carried by the alignment platform 100 according to any embodiment of the present application, so as to print a circuit on a substrate.

[0078] In the case of not contradicting each other, a person skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples.

[0079] The above description is only specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application.
