[0049] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0050] The alignment platform mechanism of the present utility model is described below with reference to the accompanying drawings.

[0051] The utility model provides a positioning platform mechanism, such as Figure 1 , Figure 2 and Figure 3 As shown, or as Figure 5 and Figure 6 As shown, the alignment platform mechanism includes:

[0052] Carrying platform 1;

[0053] A lifting module 2 is arranged on the carrying platform 1;

[0054] The alignment module 3 is installed on the lifting module 2 and can be lifted up and down under the drive of the lifting module 2. The alignment module 3 can be lifted above the carrying platform 1 under the drive of the lifting module 2, or the alignment module 3 can always be located above the carrying platform 1; and

[0055] The bearing support module 4 is movably arranged on the bearing platform 1 and has a supporting posture and an avoiding posture. By moving the bearing support module 4, the bearing support module 4 can switch between the supporting posture and the avoiding posture. In the supporting posture, the bearing support module 4 moves to the bottom of the alignment module 3. In the avoiding posture, the bearing support module 4 is staggered with the alignment module 3.

[0056] When in use, the product alignment can be achieved through the multi-axis movement of the alignment module 3 and the lifting and lowering of the lifting module 2. After the product alignment is completed, if the product needs to be pressed or the pattern transferred, the lifting module 2 can be driven to rise first to lift the alignment module 3 to a height higher than the load-bearing support module 4, and then the load-bearing support module 4 is moved so that the load-bearing support module 4 is located below the alignment module 3, and finally the height of the alignment module 3 is lowered so that the alignment module 3 is placed against the upper end of the load-bearing support module 4. Through the support of the load-bearing support module 4, the force-bearing position of the alignment module 3 can be changed from the lifting module 2 to the load-bearing support module 4, thereby avoiding deformation and damage caused by the lifting module 2 directly bearing the pressing force, thereby improving the load performance of the alignment platform mechanism.

[0057] In the embodiment of the present invention, when the lifting module 2 rises or falls, the load-bearing support module 4 can move to an evasive posture to avoid affecting the alignment module 3 .

[0058] like Figure 3 or Figure 4As shown, in the embodiment of the utility model, the alignment module and the lifting module preferably adopt a floating fit, and the floating fit refers to the presence of a floating gap in the connection part between the alignment module and the lifting module. For example, one of the alignment module 3 and the lifting module 2 can be provided with a matching groove 341, and the other can be provided with a floating connection block 24, and the floating connection block 24 extends into the matching groove 341 and is gap-fitted or slidably fitted with the matching groove 341 to achieve a floating connection between the alignment module 3 and the lifting module 2. Of course, the alignment module 3 and the lifting module 2 can also use a flexible pad or other solution to achieve a floating connection when connected.

[0059] The alignment module 3 can be driven by a screw rod, or by a cylinder, oil cylinder, electric cylinder, etc. Taking one specific embodiment as an example, a vertically extending lifting guide rail 13 is provided on the bearing platform 1, and a lifting mounting plate 34 is provided on the alignment module 3. The lifting mounting plate 34 is slidably matched with the lifting guide rail 13, a matching groove 341 is provided on the lifting mounting plate 34, and a floating connection block 24 is provided on the lifting module 2. The alignment module 3 includes a lifting screw rod 21 vertically arranged on the bearing platform 1, a lifting drive nut 22 sleeved on the lifting screw rod 21, and a lifting motor 23 that is transmission-matched with the lifting screw rod 21. The floating connection block 24 can be fixed or integrally arranged on the lifting drive nut 22. A matching groove 341 is provided on the lifting mounting plate 34, and the lifting drive nut 22 is located on the side of the lifting mounting plate 34 and is provided with a floating connection block 24 that extends into the matching groove 341, and the floating connection block 24 is clearance-matched with the matching groove 341. When the lifting drive nut 22 is lifted or lowered, it will contact the top wall or bottom wall of the matching groove 341 to drive the lifting mounting plate 34 and the alignment module 3 to lift or lower. A floating gap is set between the floating connecting block 24 and the matching groove 341 to compensate when the bearing platform 1 or the bearing support module 4 is pressed downward and deformed, thereby avoiding the lifting screw 21 from being subjected to force.

[0060] like Figure 2 or Figure 5 As shown, in the embodiment of the present utility model, the lifting module 2 can extend upward from the area between the first bearing block 41 and the second bearing block 42, and can also extend upward from the side position of the first bearing block 41 and the second bearing block 42.

[0061] like Figure 2 and Figure 3 , or as Figure 5 and Figure 6As shown, in the embodiment of the utility model, a load-bearing guide 11 is provided on the bearing platform 1, and the load-bearing guide 11 can be a guide rail, a guide groove, etc. The bearing support module 4 includes a bearing block that is slidably matched with the load-bearing guide 11 and a first driving member for driving the bearing block to move. The load-bearing guide 11 can realize the directional guided movement of the bearing block. The number of bearing blocks can be one or more. Taking two as an example, the bearing blocks include a first bearing block 41 and a second bearing block 42. The first bearing block 41 and the second bearing block 42 are arranged relatively spaced apart and driven by the first driving member. The first driving member can be a driving cylinder 43, or a screw rod, a motor, etc. By controlling the first bearing block 41 and the second bearing block 42 to move toward each other and move to the bottom of the alignment module, the bearing support module 4 can be switched to a supporting posture, and by controlling the first bearing block 41 and the second bearing block 42 to separate back to back from each other, the bearing support module 4 can be switched to an avoiding posture. Among them, when the load-bearing guide member 11 is a guide rail, the first bearing block 41 and the second bearing block 42 can be slidably matched with the guide rail through the load-bearing slider 12. The load-bearing slider 12 can be integrated with the first bearing block 41 or the second bearing block 42, or it can be a detachable connection.

[0062] like Figure 2 As shown, in the embodiment of the present utility model, in order to improve the bearing capacity of the first bearing block 41 and the second bearing block 42, the load-bearing guide member 11 is preferably a double guide rail.

[0063] like Figure 5 and Figure 6 As shown, further, in the embodiment of the utility model, an auxiliary support block 14 may be provided on the bearing platform 1, and the auxiliary support block 14 is arranged lower than the bearing block 42 and is located on the moving path of the bearing block. Continuing to take two bearing blocks as an example, in the supporting posture, the first bearing block 41 and the second bearing block 42 can be moved to the upper ends of the first bearing block 41 and the second bearing block 42 respectively and lean against them. At this time, the auxiliary support block 14 can support the first bearing block 41 and the second bearing block 42 at the bottom respectively, so as to share the force of the load-bearing guide member 11, and avoid the load-bearing guide member 11 from deforming due to the force and affecting the sliding of the support block.

[0064] It should be noted that there may be multiple auxiliary support blocks 14 , and at least two auxiliary support blocks 14 correspond one-to-one to the first bearing block 41 and the second bearing block 42 .

[0065] like Figure 1 , Figure 2 and Figure 5As shown, in the embodiment of the utility model, the alignment module 3 includes an X-axis mobile platform 31 fixedly arranged on the lifting end, a Y-axis mobile platform 32 movably arranged on the X-axis mobile platform 31, and a T-axis rotating platform 33 movably arranged on the Y-axis mobile platform 32, and a product placement position 333a is provided on the T-axis rotating platform 33. The bearing support module 4 is located below the X-axis mobile platform 31 in the supporting posture, and the bearing support module 4 is staggered with the X-axis mobile platform 31 in the avoiding posture. Through the above settings, the three-axis displacement and rotation of the alignment module 3 can be realized.

[0066] like Figure 2 As shown, in an embodiment of the utility model, the X-axis moving platform 31, and / or the Y-axis moving platform 32, and / or the T-axis rotating platform 33 are respectively driven by a driving assembly, and the driving assembly includes a driving member body and a driving connecting block, and a connecting gap or a transmission gap is provided between the driving member body and the driving connecting block. The driving component body and the driving connection block are used to be installed between two adjacent platforms. Taking the driving assembly between the X-axis moving platform 31 and the Y-axis moving platform 32 as an example, one of the driving component body and the driving connection block is installed on the X-axis moving platform 31, and the other is installed on the Y-axis moving platform 32. The driving component body is used to provide power for displacement. The driving component body can be a screw, a cylinder, an oil cylinder, an electric cylinder, etc. The driving connection block is used to transmit power. The driving component body pushes the driving connection block to move, so as to realize the displacement of the Y-axis moving platform 32 relative to the X-axis moving platform 31. When the Y-axis moving platform 32 is subjected to force to produce downward displacement, due to the connection gap or transmission matching gap between the driving component body and the driving connection block, the gap can compensate for the downward displacement of the Y-axis moving platform 32, thereby avoiding the driving component body from being subjected to force.

[0067] like Figure 2 As shown, in an embodiment of the utility model, an X-axis moving platform 31 is provided with an X-axis moving guide 312, the X-axis moving guide 312 is located below the Y-axis moving platform 32 and carries the Y-axis moving platform 32, the X-axis moving guide 312 is slidably matched with the Y-axis moving platform 32, and the driving assembly includes a first driving member body and a first driving connecting block, one of the first driving member body and the first driving connecting block is fixedly mounted on the X-axis moving platform 31, and the other is fixedly mounted on the Y-axis moving platform 32, and a connection gap or a transmission gap is provided between the first driving member body and the first driving connecting block.

[0068] like Figure 2As shown, in an embodiment of the utility model, a Y-axis moving platform 32 is provided with a Y-axis moving guide 322, the Y-axis moving guide 322 is located below the T-axis rotating platform 33 and supports the T-axis rotating platform 33, the Y-axis moving guide 322 is slidably matched with the T-axis rotating platform 33, the driving assembly includes a second driving member body and a second driving connecting block, one of the second driving member body and the second driving connecting block is fixedly mounted on the Y-axis moving platform 32, and the other is fixedly mounted on the T-axis rotating platform 33, and a connection gap or a transmission gap is provided between the second driving member body and the second driving connecting block.

[0069] In the embodiment of the present invention, the X-axis moving guide 312 and the Y-axis moving guide 322 can be structures such as guide rails and slide grooves.

[0070] In the embodiment of the utility model, the driving assembly may be a screw assembly, or may be a cylinder assembly, an electric cylinder assembly, a motor rack assembly, etc.

[0071] Take the screw assembly as an example. Figure 1 and Figure 2 As shown, in an embodiment of the utility model, the X-axis movable platform 31 includes a first platform body 311 installed on the lifting module 2 and an X-axis movable guide rail 312 arranged on the first platform body 311, the Y-axis movable platform 32 is slidably arranged on the X-axis movable guide rail 312 and is driven by a first screw rod assembly 35, the first screw rod assembly 35 includes a screw rod body and a nut connecting block, one of the screw rod body and the nut connecting block is fixedly connected to the first platform body, and the other is fixedly connected to the Y-axis movable platform 32, by arranging the X-axis movable guide rail 312 on the X-axis movable platform 31 and then arranging the Y-axis movable platform 32 on the X-axis movable guide rail 312, the X-axis displacement function of the Y-axis movable platform 32 can be realized, and at the same time, the X-axis movable guide rail 312 becomes the load-bearing part of the Y-axis movable platform 32, thereby avoiding the first screw rod assembly 35 from being subjected to force.

[0072] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the Y-axis moving platform 32 includes a second platform body 321 slidably arranged on the X-axis moving guide rail 312 and a Y-axis moving guide rail 322 arranged on the second platform body 321, the T-axis rotating platform 33 is slidably arranged on the Y-axis moving guide rail 322 and driven by the second screw assembly 36, the second platform body 321 is designed in an inverted U shape and has a support leg at the bottom, the support leg is slidably matched with the X-axis moving guide rail 312 through a slider, and the first screw assembly 35 is arranged between the bottom of the second platform body 321 and the first platform body 311 ( Figure 2(not shown), of course, the first screw assembly 35 can also be set in other positions, such as the side, and the second screw assembly 36 also includes a screw body and a nut connecting block, and its installation method is similar to that of the first screw assembly 35, which will not be repeated here. By setting the T-axis rotating platform 33 on the Y-axis moving guide rail 322, the Y-axis displacement function of the T-axis rotating platform 33 can be realized, and at the same time, the Y-axis moving guide rail 322 can become the load-bearing part of the T-axis rotating platform 33, thereby avoiding the second screw assembly 36 from being subjected to force. Among them, the rotating platform base 331 can also be an inverted U-shaped structure, and the X-axis moving platform 31, the Y-axis moving platform 32, and the T-axis rotating platform 33 can also be driven by other means, such as a cylinder, an electric cylinder, etc.

[0073] Taking the cylinder assembly as an example, a first cylinder assembly can be provided between the X-axis moving platform 31 and the Y-axis moving platform 32. The first cylinder assembly includes a first cylinder body and a first drive connecting block. The cylinder body end of the first cylinder body can be fixedly mounted on the first platform body, and the first drive connecting block can be fixedly mounted on the second platform body. The piston rod end of the first cylinder body can be connected to the first drive connecting block through a hole-shaft fit, and when the first cylinder body and the hole-shaft of the first drive connecting block are connected, the hole-shaft can be clearance-fitted to avoid force on the first cylinder body when the Y-axis moving platform 32 moves downward.

[0074] Of course, a second cylinder assembly may be disposed between the Y-axis moving platform 32 and the T-axis rotating platform 33 , and its installation method may be the same as that of the first cylinder assembly, which will not be repeated here.

[0075] like Figure 2 , Figure 5 and Figure 6 As shown, in an embodiment of the utility model, the T-axis rotating platform 33 includes a rotating platform base 331 slidably arranged on the Y-axis moving guide rail 322, a rotating support connecting member 332 vertically rotatingly arranged on the rotating platform base 331, and an alignment seat 333 arranged on the rotating support connecting member 332, the product placement position 333a is arranged on the alignment seat 333, and the rotating support connecting member 332 can be driven by a third screw assembly 37.

[0076] like Figure 6 and Figure 7As shown, the third screw assembly 37 also includes a screw body 371 fixedly set on the rotating platform base 331 and a nut connecting block 372 sleeved on the screw body 371, but unlike the first screw assembly 35 and the second screw assembly 36, the nut connecting block 372 of the third screw assembly 37 is also provided with a driven guide rail 373 which is horizontal and perpendicular to the screw body 371, and the third screw assembly 37 also includes a sliding seat 374 slidingly matched with the driven guide rail 373 and a connecting shaft 375 vertically rotatably arranged on the sliding seat 374, and the connecting shaft 375 is rotatably connected to the alignment seat 333. When the screw body 371 in the third screw assembly 37 rotates, it will push the nut connection block 372 to move along the extension direction of the screw, and when the nut connection block 372 moves, the alignment seat 333 will be affected by the deflection torque and will have a tendency to rotate. The rotation of the alignment seat 333 will drive the sliding seat 374 to slide on the driven guide rail 373 to compensate for the displacement difference between the screw body 371 and the rotating support connector 332 during the arc motion. Through the above arrangement, the rotation drive of the T-axis rotating platform 33 can be achieved by only one set of screw assemblies. At the same time, the alignment seat 333 is moved by the Y-axis guide rail 322 when bearing force, which can avoid the third screw assembly 37 from being subjected to force. Of course, the rotating support connector 332 can also be driven directly by a vertically arranged motor or other driving member.

[0077] like Figure 6 As shown, in the embodiment of the utility model, the rotating support connecting member 332 can be a cross roller bearing, the outer ring 332a of the cross roller bearing is connected to the rotating platform base 331, and the inner ring 332b of the cross roller bearing is connected to the alignment seat 333. By setting the rotating support connecting member 332 as a cross roller bearing, the load bearing capacity of the alignment platform mechanism can be further increased. Of course, the rotating support connecting member 332 can also be a load bearing bearing, an annular slide rail, etc.

[0078] In the embodiment of the utility model, the screw body 371 and the nut connecting block 372 in the first screw assembly 35, the second screw assembly 36, and the third screw assembly 37 are clearance transmission matched. Through the clearance transmission match, when the Y-axis moving platform 32 or the T-axis rotating platform 33 is subjected to pressure and a small displacement occurs, the floating gap between the nut connecting block 372 and the screw body 371 can compensate for the displacement, and avoid the force generated by the displacement from being transmitted to the screw body 371. It should be noted that the transmission match between the screw body 371 and the nut connecting block 372 needs to be ensured during the clearance match. Of course, when the drive assembly is a motor rack assembly, the position of the transmission matching gap can be set at the meshing of the rack, that is, when the rack and the gear are meshed, a meshing gap can be set between the teeth and the tooth groove, or when the drive assembly is a cylinder assembly or an electric cylinder assembly, a connection gap can be set at the connection between the drive body and the drive connecting block, and the connection gap can be the matching gap between the sliding groove and the sliding block, or the matching gap between the hole shaft, or the chain soft connection between the drive body and the drive connecting block, etc.

[0079] To achieve the above purpose, the utility model also provides a printing device, wherein the printing device includes the alignment platform mechanism described above. Since the printing device adopts all the technical solutions of the above embodiments, it at least has the beneficial effects brought by the above embodiments, which will not be repeated here.

[0080] In summary, the alignment platform mechanism in the utility model can prevent the lifting module 2, the first screw assembly 35, the second screw assembly 36, the third screw assembly 37 and other driving components from being subjected to force when the alignment module is pressed down, and convert the pressure force borne by the alignment module 3 into support by the load-bearing platform 1 and the load-bearing support module 4, thereby improving the load capacity of the alignment platform mechanism and making the platform more suitable for pressing or transfer working scenarios.
