The main function of the alignment platform is to achieve precise positioning and alignment of workpieces or components by accurately controlling the position and posture of the upper plate. The power shaft is responsible for supporting the upper plate and driving it to move, while the driven shaft is used to evenly disperse the vertical downward force and reduce the burden on the power mechanism, thereby achieving the purpose of force balance and extending life.

[0003] In the exemplary document with publication number CN220050796U, the alignment platform adopts a structure of three power shafts and one driven shaft, and these shafts are arranged in parallel on the lower plate and connected to the upper plate through a fixed structure. The power shaft includes a motor, a moving part and a rotating part, and the position of the upper plate is adjusted by controlling these parts. However, since the three power shafts and the driven shaft are arranged horizontally on the lower plate, they need to maintain a certain distance from each other to avoid interference, which results in a larger footprint of the entire platform. This design limits the application of the alignment platform in space-constrained environments, affects the applicability and market competitiveness of the alignment platform, and it is urgent for those skilled in the art to make improvements on this.

[0030] The utility model provides a positioning platform.

[0031] In the embodiment of the present utility model, Figures 1 to 3 As shown, the alignment platform includes a fixed plate 1, a Y-axis module 2, a follower 3, a first X-axis module 4, a second X-axis module 5 and an upper plate 8. The Y-axis module 2 is arranged on the fixed plate 1 so as to be reciprocatingly movable along the Y-axis direction; the follower 3 is arranged on the fixed plate 1 so as to be reciprocatingly movable along the Y-axis direction, and the follower 3 is located on the moving path of the Y-axis module 2; the first X-axis module 4 is arranged on the side of the Y-axis module 2 facing away from the fixed plate 1 so as to be reciprocatingly movable along the X-axis direction, The axis direction is perpendicular to the Y-axis direction; the second X-axis module 5 is arranged on the side of the follower 3 facing away from the fixed plate 1 and can be reciprocated along the X-axis direction; the upper plate 8 is rotatably connected to the side of the first X-axis module 4 facing away from the fixed plate 1 and the side of the second X-axis module 5 facing away from the fixed plate 1 respectively; wherein the upper plate 8 can move under the drive of any one of the Y-axis module 2, the first X-axis module 4 and the second X-axis module 5, and drive the follower 3 to move in the Y-axis direction.

[0032] Specifically, the Y-axis module 2 can be arranged on the fixed plate 1 to reciprocate along the Y-axis direction, which can be achieved through a variety of structures. For example, a slide rail guide structure can be adopted, and a slider is arranged on the Y-axis module 2 to cooperate with the slide rail fixed on the fixed plate 1; or a linear bearing system can be used, and the Y-axis module 2 is connected to the guide rail on the fixed plate 1 through a bearing sleeve. The reciprocating installation method of the follower 3, the first X-axis module 4 and the second X-axis module 5 can refer to the installation method of the Y-axis module 2, and will not be repeated here.

[0033] The movement of the Y-axis module 2, the driven member 3, the first X-axis module 4 and the second X-axis module 5 can be controlled in a variety of ways. Manual control can be adopted, and the operator directly manually adjusts the position of each module; or these modules themselves include a drive system, such as a stepper motor, a servo motor, a cylinder or a hydraulic cylinder, which cooperates with a controller to achieve precise positioning.

[0034] The upper plate 8 is rotatably connected with the first X-axis module 4 and the second X-axis module 5, respectively, which can be achieved by bearings or hinges. This connection method gives the upper plate 8 greater flexibility. The movement of the upper plate 8 is achieved by the coordinated work of the Y-axis module 2, the first X-axis module 4 and the second X-axis module 5. When only the Y-axis module 2 moves, the upper plate 8 will translate along the Y-axis direction.

[0035] When only one X-axis module moves, taking the movement of the first X-axis module 4 as an example, it will directly drive the end of the upper plate 8 connected to it to move. At the same time, the follower 3 will produce a corresponding movement in the Y-axis direction. The key to this coordinated movement is that the Y-axis movement of the follower 3 compensates for the displacement requirement of the other end of the upper plate 8 (the end connected to the second X-axis module 5) in the Y-axis direction. Specifically, when the first X-axis module 4 moves in the positive direction along the X-axis, it will push the upper plate 8 to start rotating. In this process, in order to keep the distance between the two connection points of the upper plate 8 unchanged, the rigid structure of the upper plate 8 and the rigid structure of the second X-axis module 5 will pull the follower 3 to move in the Y-axis, which will cause the connection point between the upper plate 8 and the second X-axis module 5 to move in the Y-axis direction, thereby keeping the distance between the two connection points of the upper plate 8 unchanged.

[0036] When the two X-axis modules move in the same direction, the upper plate 8 will translate along the X-axis direction. In this case, the two X-axis modules move at the same speed and direction, and the two connection points of the upper plate 8 move in the same direction at the same time. Since the relative position between the two connection points remains unchanged, the upper plate 8 will remain horizontal and translate along the X-axis direction. This movement does not require the follower 3 to compensate in the Y-axis direction because the upper plate 8 does not tilt or rotate.

[0037] When the two X-axis modules move in opposite directions, the upper plate 8 rotates around the vertical axis. When the first X-axis module 4 moves in the positive direction of the X-axis and the second X-axis module 5 moves in the negative direction of the X-axis (or vice versa), the two connection points of the upper plate 8 move in opposite directions. This movement causes the upper plate 8 to rotate around its center axis. As the upper plate 8 rotates, its connection points not only move in the X-axis direction, but also produce displacements in the Y-axis direction. The follower 3 will move in the Y-axis direction accordingly to compensate for this Y-axis displacement. This compensation mechanism ensures that the upper plate 8 can rotate smoothly around its center point without causing additional translation or tilt.

[0038] When the Y-axis module 2 and the X-axis module move simultaneously, the upper plate 8 can achieve compound motion, including translation and rotation in any direction.

[0039] It can be understood that the alignment platform of the technical solution of the utility model is provided by setting the Y-axis module 2 and the follower 3 on the fixed plate 1, and then installing the first X-axis module 4 and the second X-axis module 5 thereon respectively. This vertically stacked design greatly reduces the horizontal footprint of the platform. At the same time, since the X-axis module is directly mounted on the Y-axis module 2 and the follower 3, the spacing that needs to be maintained between the shafts in the traditional design is eliminated, and the overall size is further compressed. In addition, the follower 3 in the present design can move along the Y-axis direction and work in conjunction with the Y-axis module 2 without the need for an additional independent drive system, which not only simplifies the structure but also reduces the required space. The rotational connection design of the upper plate 8 and the X-axis module, combined with the mobility of the Y-axis module 2 and the follower 3, enables the system to achieve a wide range of X and Y direction movement and rotation adjustment while maintaining a compact structure, without the need to expand the stroke by increasing the size of the lower plate as in the traditional design. This innovative design not only significantly reduces the footprint of the alignment platform, but also improves the space utilization efficiency, making it more suitable for application in space-constrained environments while maintaining a high degree of functionality and flexibility.

[0040] Optionally, the Y-axis module 2 includes a Y-axis driving member 21 and a Y-axis moving member 22 which is transmission-connected to the Y-axis driving member 21; the Y-axis moving member 22 is arranged on the fixed plate 1 so as to be reciprocatingly movable along the Y-axis direction; the follower 3 is arranged on the side of the Y-axis moving member 22 which is away from the Y-axis driving member 21; and the Y-axis driving member 21 drives the Y-axis moving member 22 to reciprocate in the Y-axis direction.

[0041] Specifically, the Y-axis drive 21 can be in various forms, such as a motor (such as a stepper motor or a servo motor), a cylinder or a hydraulic cylinder, etc. The selection of the Y-axis drive 21 depends on the requirements of the specific application, such as the required accuracy, speed and force.

[0042] The Y-axis moving part 22 is connected to the Y-axis driving part 21 by transmission, and this transmission connection can be realized in a variety of ways. For example, a screw nut mechanism can be used, wherein the Y-axis driving part 21 drives the screw to rotate, and the nut matched with the screw drives the Y-axis moving part 22 to move. Another way is to use a belt drive, wherein the Y-axis driving part 21 drives the Y-axis moving part 22 to move through a synchronous belt. Gear rack transmission, or linear motor and the like can also be used.

[0043] By separating the driving function and the motion function (undertaken by the Y-axis driving component 21 and the Y-axis moving component 22 respectively), the system can select and optimize each component more flexibly. For example, different types or specifications of driving components can be selected as needed without changing the structure of the entire Y-axis module 2. At the same time, this design is also convenient for maintenance and upgrading, because the driving component or the moving component can be replaced or repaired separately without affecting other parts of the entire system.

[0044] Optionally, in some embodiments, the Y-axis moving component 22 can move to a position where it abuts against the follower 3. Specifically, when the Y-axis moving component 22 abuts against the follower 3, they can move together as a whole. This design enables the system to achieve synchronous movement of the Y-axis moving component 22 and the follower 3 when necessary, increasing the flexibility and functionality of the system. In addition, the abutment between the Y-axis moving component 22 and the follower 3 can be used as a simple position feedback mechanism. For example, a contact sensor can be installed at the abutment point to detect whether the Y-axis moving component 22 has reached the limit position, which provides additional information for system control.

[0045] Optionally, the structure of the Y-axis moving component 22 is the same as that of the driven component 3. This design greatly simplifies the production process of the parts. Since the Y-axis moving component 22 and the driven component 3 use the same structure, the manufacturer only needs to produce one component to meet the needs of two different positions at the same time. This large-scale production not only reduces production costs, but also improves production efficiency. At the same time, since the same component is produced, it is easier to ensure quality consistency.

[0046] Secondly, this design increases the flexibility and maintainability of the system. When repairing or replacing, the Y-axis moving part 22 and the driven part 3 can be used interchangeably, which greatly simplifies spare parts management and maintenance. If one of the parts fails, it can be quickly replaced with another identical part, reducing downtime. In addition, this interchangeability also facilitates the upgrade and transformation of the system, because new designs or improvements can be easily tried in different locations.

[0047] From a design perspective, the same structure of the Y-axis moving part 22 and the driven part 3 also simplifies the design process of the entire alignment platform. Designers only need to focus on optimizing one structure to meet the needs of two functional parts at the same time. This not only saves design time, but also helps to improve the consistency and reliability of the entire system.

[0048] In actual operation, the Y-axis moving part 22 and the follower 3 with the same structure may exhibit similar motion characteristics, which is conducive to the balance and stability of the system. For example, they may have similar friction coefficients, inertia characteristics, etc., which makes the behavior of the system more predictable and easy to control when performing precise alignment.

[0049] Optionally, the first X-axis module 4 includes a first mounting plate 41, a first X-axis moving component 42 and a first X-axis driving component 43. The first mounting plate 41 is fixed to the side of the Y-axis moving component 22 facing away from the fixed plate 1. The first X-axis moving component 42 can be reciprocated and moved on the first mounting plate 41 along the X-axis direction. The first X-axis driving component 43 is fixed on the first mounting plate 41 and is transmission-connected to the first X-axis moving component 42 to drive the first X-axis moving component 42 to move in the X-axis direction. The upper plate 8 is rotatably arranged on the side of the first X-axis moving component 42 facing away from the fixed plate 1.

[0050] Specifically, the first X-axis moving component 42 can be reciprocated along the X-axis direction and is arranged on the first mounting plate 41. This design can be implemented in many ways, such as using a linear guide and slider system, or a combination of precision bearings and guides. The first X-axis driving component 43 is fixed to the first mounting plate 41 and is transmission-connected to the first X-axis moving component 42. This design allows the drive system and the moving parts to form a compact whole. The driving component can be in various forms, such as a stepper motor, a servo motor or a linear motor. The transmission connection can be achieved through a variety of mechanisms, such as a screw nut, a belt drive or a gear rack.

[0051] Optionally, the second X-axis module 5 includes a second mounting plate 51, a second X-axis moving component 52 and a second X-axis driving component 53, the second mounting plate 51 is fixed to the side of the driven component 3 facing away from the fixed plate 1, the second X-axis moving component 52 is arranged on the second mounting plate 51 so as to be reciprocatingly movable along the X-axis direction, the second X-axis driving component 53 is fixed to the second mounting plate 51 and is transmission-connected with the second X-axis moving component 52 to drive the second X-axis moving component 52 to move in the X-axis direction, and the upper plate 8 is rotatably arranged on the side of the second X-axis moving component 52 facing away from the fixed plate 1; wherein,

[0052] The Y-axis drive 21, the first X-axis drive 43 and the second X-axis drive 53 are arranged in the same structure; specifically, all drive systems adopt the same design and may use the same type of motor or driver. This uniformity greatly simplifies the control and maintenance of the system.

[0053] The first mounting plate 41 and the second mounting plate 51 are configured with the same structure; specifically, such a design ensures that the two X-axis modules have the same mounting base, which is beneficial to maintaining the symmetry and balance of the system.

[0054] The Y-axis moving part 22, the first X-axis moving part 42 and the second X-axis moving part 52 are arranged in the same structure. Specifically, such a design enables all moving parts to be interchangeable, greatly simplifying the production and maintenance process.

[0055] It is not difficult to understand that manufacturers only need to produce one drive part, one mounting plate and one moving part to assemble the moving part of the entire system. This not only reduces production costs, but also improves production efficiency and quality consistency. Secondly, this design greatly improves the maintainability and flexibility of the system. Since the various components are the same, maintenance personnel can easily replace components without considering the compatibility issues between different components. At the same time, this also facilitates the upgrade and modification of the system, because new designs or improvements can be easily tried in different locations. Furthermore, standardized component design is conducive to improving the performance consistency of the entire system. Since all axes use the same components, their motion characteristics will be more consistent, which will help achieve more precise coordinated control.

[0056] Optionally, the first X-axis driving member 43 and the second X-axis driving member 53 are located on the same side of the upper plate 8 .

[0057] Specifically, placing the two X-axis drive components on the same side of the upper plate 8 can make the structure of the entire system more compact and symmetrical. This layout can reduce the footprint of the entire alignment platform, making it more suitable for use in space-constrained environments. Secondly, this design facilitates centralized management and control of the drive system. Since the two drive components are located in close positions, cable management, heat dissipation design and maintenance operations can be performed more easily. For example, a common control box or cooling system can be used to manage the two drive components, simplifying the overall structure of the system.

[0058] Optionally, the first mounting plate 41 includes a horizontal plate 411 and a vertical plate 412 vertically arranged on the horizontal plate 411, the horizontal plate 411 is fixed to the side of the Y-axis moving component 22 facing away from the fixed plate 1, the first X-axis moving component 42 can be reciprocated along the X-axis direction and is arranged on the horizontal plate 411, the first X-axis driving component 43 is fixed to the side of the vertical plate 412 facing away from the first X-axis moving component 42, and the driving shaft of the first X-axis moving component 42 passes through the vertical plate 412 and is connected to the first X-axis moving component 42.

[0060] The upper plate 8 is rotatably connected to the second X-axis module 5 via the second bearing 7 .

[0061] Specifically, the bearing not only allows the upper plate 8 to rotate relative to the X-axis module, but also can bear certain radial and axial loads. This connection method provides good rotational freedom for the upper plate 8 while maintaining the stability and accuracy of the connection.

[0062] Furthermore, the first bearing 6 includes a first inner ring 61 and a first outer ring 62, one of the first inner ring 61 and the first outer ring 62 is fixedly connected to the upper plate 8 by bolts, and the other of the first inner ring 61 and the first outer ring 62 is fixedly connected to the first X-axis moving component 42 of the first X-axis module 4.
