Description

[0001] The present invention relates to the technical field of regulating components, and in particular to a rigid-flexible differential regulating component and its posture adjustment application. Background Art

[0002] In the field of precision measurement and micro-manipulation, the posture adjustment of measuring heads such as microscopes, confocals, white light interferometers, and operating heads such as probes, dispensing heads, and bonding heads is crucial to ensure that they maintain precise verticality with the operating object. At present, the widely used deflection and pitch adjustment mechanisms mostly adopt a combination of screws and spring resets to achieve posture adjustment. However, a large number of practices and studies have shown that this existing adjustment scheme has significant drawbacks. In terms of accuracy, due to the influence of factors such as the manufacturing tolerance and elastic deformation of the screws and springs themselves, it is difficult to achieve high-precision posture fine-tuning, and it is impossible to meet the increasingly stringent requirements for measurement and operation accuracy. At the same time, its carrying capacity is also limited. When facing a large load, the elastic properties of the spring are prone to change, resulting in the inability of the adjustment mechanism to stably maintain the posture of the operating head, thereby affecting the working performance and reliability of the entire system. In view of this, the present invention proposes a rigid-flexible differential adjustment component and its posture adjustment application. Summary of the invention

[0003] The purpose of the present invention is to propose a rigid-flexible differential adjustment component and its attitude adjustment application to address the problem that the deflection and pitch adjustment mechanism in the background technology has problems such as difficulty in meeting accuracy requirements and limited load-bearing capacity due to factors such as manufacturing tolerances of screws and springs, elastic deformation and elastic characteristics being affected by loads, which in turn affects the working performance and reliability of the system.

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Embodiment 1

[0035] like Figure 1 As shown, a rigid-flexible differential adjustment component proposed by the present invention includes a mounting block 1, an adjustment block 2 relatively parallel to the mounting block 1, a threaded rod 3 is threadedly connected in the adjustment block 2, a first connecting block 11 is arranged on one side of the mounting block 1, and a second connecting block 21 is connected on one side of the adjustment block 2. When an external force is applied to the threaded rod 3 to make it rotate, according to the principle of thread transmission, after the second connecting block 21 on one side of the adjustment block 2 is fixedly installed, the adjustment block 2 will perform a linear displacement along the axial direction of the threaded rod 3, thereby accurately adjusting the distance between the mounting block 1 and the adjustment block 2. And the precise adjustment of this distance is the key to achieving posture adjustment.

[0036] For details, please refer to Figure 2 , the above-mentioned adjustment component also includes a flexible component 4 for controlling the mounting block 1 and the adjustment block 2 to be in a parallel state. The flexible component 4 is at least one group of flexible hinges. In this embodiment, a two-piece structure is adopted for upper and lower parallel installation. Its unique flexible characteristics can ensure that the mounting block 1 and the adjustment block 2 always remain in a parallel state during and after the posture adjustment process. This parallel state is crucial to maintaining the stability and accuracy of the entire adjustment system. The connection position of the flexible component 4 has specific requirements, and it can be connected between the mounting block 1 and the first connecting block 11, or between the adjustment block 2 and the second connecting block 21. It should be noted that the mounting block 1 and the first connecting block 11 or the adjustment block 2 and the second connecting block 21 are always fixedly set, so as to ensure that the mechanical properties of the entire structure are stable and reliable when the flexible component 4 is in effect.

[0037] The threaded rod 3 is a bolt or a screw, both of which are common threaded transmission components with good transmission accuracy and reliability. When the threaded rod 3 is rotated, it can drive the adjustment block 2 to move accurately due to its matching with the thread of the adjustment block 2. The moving distance is closely related to the number of rotations of the threaded rod 3 and the pitch.

[0038] like Figure 4 As shown, a driving assembly is installed at one end of the threaded rod 3 away from the adjusting block 2. The driving assembly adopts a knob 8. The knob 8 is fixedly connected to the end of the threaded rod 3 away from the adjusting block 2. The knob 8 is rotatably connected to the side of the mounting block 1. This design allows the knob 8 to remain in place and rotate. Moreover, since the knob 8 has a large operating area and a good grip, it is greatly convenient for the operator to rotate the threaded rod 3, providing convenience for the posture adjustment operation.

[0039] At the same time, the best fixed position of the flexible component 4 is between the adjustment block 2 and the second connecting block 21. At this time, the mounting block 1 and the first connecting block 11 are fixedly arranged. In this way, when the driving component performs an adjustment action, the flexible component 4 will not generate additional force on the driving component during the deformation process, thereby avoiding driving the driving component to move, and ensuring the accuracy and stability of the drive adjustment.

[0040] Embodiment 2

[0041] See also Figure 3 This embodiment is applied to a posture adjustment platform. On the basis of the first embodiment, the posture adjustment platform also includes a fixed plate 5 and a movable plate 6. The fixed plate 5 is fixedly arranged. The fixed plate 5 plays a role of basic support and fixing in the whole system. Two groups of the above-mentioned rigid-flexible differential adjustment components are arranged between the fixed plate 5 and the movable plate 6. An elastic column 7 is installed at the edge of one side of the movable plate 6. One end of the elastic column 7 is fixedly connected to the fixed plate 5. One end of the elastic column 7 is connected to the fixed plate 5 by reliable fixed connection methods such as welding and riveting, so that the movable plate 6 is firmly connected to the top of the fixed plate 5 through the elastic column 7. The first connecting block 11 is connected to the fixed plate 5 or the movable plate 6, and the second connecting block 21 is connected to the fixed plate 5 or the movable plate 6. The first connecting block 11 and the second connecting block 21 are always installed on the same side in parallel up and down on the sides of the fixed plate 5 and the movable plate 6. If the flexible component 4 is located between the mounting block 1 and the first connecting block 11, the adjusting block 2 and the second connecting block 21 on the other side can be manufactured as one piece; conversely, when the flexible component 4 is installed between the adjusting block 2 and the second connecting block 21, the mounting block 1 and the first connecting block 11 can be manufactured as one piece.

[0042] In addition, the elastic column 7 and the two groups of threaded rods 3 are arranged at equal intervals around the central axis of the movable plate 6, and the three are at an angle of 120° to the central axis of the movable plate 6. This special layout design allows the spacing between the adjustment block 2 and the mounting block 1 to be accurately adjusted when the threaded rod 3 is rotated. As the spacing changes, the movable plate 6 will produce a pitch tilt with the elastic column 7 as the center, thereby achieving precise adjustment of the posture of the movable plate 6, which is particularly suitable for optical equipment, such as the angle adjustment of an optical lens. If the rigid-flexible differential adjustment components on both sides are adjusted at different spacings at the same time, the movable plate 6 will deflect, so that different adjustment purposes of pitch and deflection can be achieved at the same time.

[0043] In this embodiment, when the posture needs to be adjusted, the operator only needs to turn the knob 8, and the rotation of the knob 8 will drive the threaded rod 3 fixedly connected thereto to rotate synchronously. During the rotation process, the threaded rod 3 drives the adjustment block 2 to move by virtue of its threaded cooperation with the adjustment block 2. The movement of the adjustment block 2 will cooperate with the flexible component 4, and through the transmission of force and the synergistic effect of the structure, the moving plate 6 will be driven to deflect around the elastic column 7, and finally the posture of the moving plate 6 can be accurately adjusted.

[0044] Embodiment 3

[0045] like Figure 5 As shown, compared with the first embodiment, the drive assembly is replaced. At this time, the drive assembly can adopt an electric drive mechanism 9. The electric drive mechanism 9 includes a mounting frame 91 fixedly connected to the side of the mounting block 1 away from the adjustment block 2, and the mounting frame 91 is connected by bolts, welding, etc. to ensure that its position remains fixed in the entire system. A servo motor 92 is installed on the side of the mounting frame 91 away from the mounting block 1. Similarly, the servo motor 92 is also fixed by corresponding fixing measures to ensure the stability of its position. The output end of the servo motor 92 is connected to the threaded rod 3 through a coupling 93, and this connection method can effectively transmit the output torque of the servo motor 92. When the servo motor 92 is started, the rotation of its output shaft will drive the threaded rod 3 to rotate without loss through the coupling 93, thereby realizing precise adjustment of the position of the adjustment block 2.

[0046] See also Figure 6 The mounting block 1 is provided with a bearing 94, which is in rotational cooperation with the threaded rod 3. The bearing 94 is in precise rotational cooperation with the threaded rod 3. The friction and shaking of the threaded rod 3 during rotation can be effectively reduced, and the position of the threaded rod 3 can be ensured to be stable. The stability of the threaded rod 3 ensures that the flexible component 4 will not cause the threaded rod 3 to tilt through the adjustment block 2, thereby ensuring that the mounting block 1 and the adjustment block 2 are always arranged in parallel, which provides an important guarantee for the accuracy and stability of the entire adjustment system.

[0047] In this embodiment, when adjusting the posture, the operator only needs to start the servo motor 92, and the servo motor 92 will respond quickly, driving the threaded rod 3 to rotate at high speed and accurately through the coupling 93. When the threaded rod 3 rotates, it will drive the adjustment block 2 to move according to the principle of thread transmission. The movement of the adjustment block 2 cooperates with the flexible component 4, and through a series of structural synergies and mechanical effects, drives the moving plate 6 to deflect around the elastic column 7, and finally realizes the precise adjustment of the posture of the moving plate 6.

[0048] Embodiment 4

[0049] like Figure 5 and Figure 6 As shown, based on the above-mentioned embodiment 2 or embodiment 3, the present invention proposes a new posture adjustment platform, which has three groups of rigid-flexible differential adjustment components. There is no need to install elastic columns 7 between the fixed plate 5 and the movable plate 6. The three groups of rigid-flexible differential adjustment components are arranged in an isosceles triangle around the fixed plate 5 and the movable plate 6, providing a stable support and adjustment structure for the posture adjustment platform, and having extremely high bearing capacity.

[0050] In this embodiment, when the posture needs to be adjusted, the operator starts three groups of servo motors 92. The three groups of servo motors 92 will independently drive the three groups of threaded rods 3 to rotate through their respective couplings 93. During the rotation process, the threaded rod 3 drives the adjustment block 2 to move by virtue of its threaded cooperation with the adjustment block 2. By accurately controlling the three groups of threaded rods 3 to rotate different numbers of turns, the flexible component 4 can be cleverly matched to make the mobile plate 6 produce a rich and diverse posture change, thereby achieving all-round and high-precision adjustment of the posture of the mobile plate 6. At the same time, when it is necessary to realize the lifting of the mobile plate 6, the operator can control the system so that the three groups of threaded rods 3 rotate the same number of turns at the same time. In this case, the three groups of adjustment components will act synchronously to achieve the smooth lifting of the mobile plate 6, greatly expanding the function and application range of the posture adjustment platform, and is particularly suitable for the focusing process of optical lenses. Therefore, in this embodiment, angle and height adjustment in different directions can be achieved to achieve the purpose of rapid adjustment of multiple postures.

[0051] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
