Description

Technical Field

[0001] The utility model belongs to the technical field of experimental instruments, and in particular relates to a platform device capable of replacing a plurality of loading platforms. Background Art

[0002] In the process of observing the object to be measured on the measuring platform, the microscope device performs multi-directional observation of the object to be measured by moving the measuring platform in the horizontal straight line direction; however, due to the irregularity of the surface morphology of the existing object to be measured, the horizontal straight line movement of the measuring platform alone cannot meet the multi-directional observation of the object to be measured. At this time, the position of the object to be measured on the measuring platform can only be changed manually, and the position of the object to be measured can be continuously adjusted to observe the morphology of the object to be measured in different directions. Or the object to be measured on the measuring platform can be driven to move by the overall rotation of the measuring platform. However, manually changing the position of the object to be measured on the measuring platform is likely to cause problems such as low observation efficiency and uncontrollable observation azimuth parameters; and the overall rotation of the measuring platform will change the center position of the measuring platform, because the object to be measured placed near the center of the measuring platform changes greatly with the rotation position of the measuring platform, which is not convenient for microscope observation. Therefore, it is urgent to design a platform device including a rotatable circular stage with multiple replaceable stages. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model proposes a platform device capable of replacing multiple loading platforms.

[0016] Beneficial effects of the utility model: The utility model proposes a platform device that can replace multiple stages, including: an elastic interference component, which is in elastic fixed cooperation contact with the circular stage on the first platform through one of the first interference member and the second interference member. Based on the elastic interference component, the circular stage can be rotated and moved relative to the first platform, and then the object to be measured on the measuring platform can rotate with the circular stage, which solves the problems of low efficiency of multi-directional observation of the object to be measured and uncontrollable observation azimuth parameters.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In this scheme, based on the measurement platform of the microscope, a platform device with multiple replaceable stages is constructed to meet the observation requirements of the object to be measured on the measurement platform. Figure 3 As shown, a platform device capable of replacing multiple loading platforms includes an elastic abutment assembly 6, which is in elastic fixed cooperation with a circular loading platform 2 on a first platform 1 through one of a first abutment member 61a and a second abutment member 61b.

[0029] Furthermore, the circular stage 2 is a movable circular stage or a fixed circular stage. The elastic abutment component 6 is arranged in the first platform 1 and is fixedly connected to the first platform; the first platform 1 is provided with a snap-fitting portion 5, and the circular stage 2 and the snap-fitting portion 5 are snap-fitted under the elastic fixed contact of the elastic abutment component 6.

[0030] Specifically, the engaging portion 5 is a groove provided on the surface of the first platform 1. And after each circular stage 2 is engaged with the first platform 1 through the groove of the engaging portion 5, the surface of each circular stage 2 is on the same horizontal plane, that is, when the circular stage 2 is a movable circular stage and is engaged with the first platform 1, the surface of the circular stage 2 is on the same horizontal plane as when the circular stage 2 is a fixed circular stage and is engaged with the first platform 1, which is convenient for the microscope to uniformly manage the observation height of the object to be measured on the circular stage 2. Specifically, the circular stage 2 is engaged with the groove of the engaging portion 5, so that the circular stage 2 is embedded in the groove. The engaging portion 5 provided on the first platform 1 can be based on a device integrally formed with the first platform 1, or can be based on an assembly connection between a groove member and the first platform 1. Preferably, the engaging portion 5 can adopt a stepped groove, so that one of the first abutment 61a and the second abutment 61b is in elastic fixed contact with the circular stage 2 on the first platform 1. After each circular stage 2 is connected to the first platform 1, the surface of each circular stage 2 is in the same horizontal plane; preferably, after each circular stage 2 is connected to the first platform 1, the surface of each circular stage 2 is in the same horizontal plane as the surface of the first platform 1. The movable circular stage means that after the circular stage 2 is connected to the first platform 1, the plane of the circular stage 2 can rotate and move relative to the first platform 1; the fixed circular stage means that after the circular stage 2 is connected to the first platform 1, the plane of the circular stage 2 cannot move relative to the first platform 1.

[0031] Furthermore, the elastic resistance component 6 is provided with a first resistance member 61a and a second resistance member 61b which are in elastic fixed fitting contact with each circular stage 2; the movable circular stage or the fixed circular stage is in contact with the first resistance member 61a and the second resistance member 61b which are in correspondence with each other, and based on the elasticity of the elastic resistance component 6, that is, the elastic resistance component 6 can be elastically deformed, so that each resistance member 61 elastically fixes the corresponding circular stage 2, thereby making the circular stage 2 movable relative to the first platform 1 when it is a movable circular stage, and immovable relative to the first platform 1 when it is a fixed circular stage. Among them, the first resistance member 61a is in elastic fixed fitting contact with the fixed circular stage; the second resistance member 61b is in elastic fixed fitting contact with the movable circular stage. The number of resistance members corresponding to each circular stage 2 is at least one, and the specific number of resistance members can be set based on the resistance member structure and the structure of the circular stage 2. In addition, the number of the elastic resistance components 6 is at least one, which is specifically set based on the structure of the circular stage 2 and the moving mode of the movable circular stage. Specifically, the first resistance member 61a and the second resistance member 61b are protrusions arranged on the elastic resistance component 6; the elastic resistance component 6 elastically contacts the circular stage 2 through the protrusions; the protrusions protrude in the direction of the circular stage 2 on the first platform 1, and the protrusions can be in the shape of blocks, sheets, etc. but not limited to them. The first resistance member 61a and the second resistance member 61b contact the circular stage 2 through contact modes such as point contact, line contact, and surface contact, but not limited to them. Preferably, the first resistance member 61a and the second resistance member 61b contact the circular stage 2 based on an arc-shaped contact surface, and the arc-shaped contact surface reduces the friction and wear of the connection between the circular stage 2 and the first platform 1, especially when the circular stage 2 is made of glass, thereby extending the service life of the circular stage 2.

[0032] In order to make the engaging portion 5 provided on the first platform 1 adaptable to both the movable circular stage and the fixed circular stage; therefore, based on the elastic fixed matching contact between the circular stage 2 and the first platform 1 in the elastic interference assembly 6, that is, based on the elastic fixed matching contact between the circular stage 2 and the first platform 1 in one of the first interference member (61a) and the second interference member (61b) in the elastic interference assembly 6, the first interference member 61a and the second interference member 61b move elastically synchronously. In addition, since the first interference member 61a and the second interference member 61b will move due to the elastic deformation of the elastic interference assembly 6 during the process of fixing the circular stage, in order to make the gap between the circular stage 2 and the first platform 1 as small as possible when the circular stage 2 is connected to the first platform 1, the first platform 1 is provided with a gap for the elastic movement of the first interference member 61a and the second interference member 61b, that is, the space for the elastic interference assembly 6 to move. Furthermore, the elastic resistance component 6 is based on the elastic cooperation and contact between the clamping portion 5 and the circular stage 2, thereby realizing elastic fixation of the circular stage by the resistance member. Therefore, the clamping portion 5 is provided with a hole 8 for placing the elastic resistance component 6. During the process in which each resistance member in the elastic resistance component 6 contacts and fixes the circular stage 2 through the hole 8 provided in the clamping portion 5, the elastic resistance component 6 moves in the gap provided in the first platform 1, thereby achieving the effect of elastically fixing the circular stage.

[0033] Furthermore, based on the circular stage 2 being connected to the first platform 1 under the elastic fixed fitting contact of the elastic interference assembly 6, the first interference member 61a and the second interference member 61b move elastically synchronously, so that the circular stage 2 adopts a movable circular stage or a fixed circular stage, and under the synchronous elastic movement of each interference member corresponding to each circular stage 2, when the circular stage 2 is a movable circular stage or a fixed circular stage, the first interference member 61a or the second interference member 61b contacts the corresponding circular stage 2; that is, when the circular stage 2 is a movable circular stage, the first interference member 61a corresponding to the fixed circular stage does not contact the movable circular stage, and when the circular stage 2 is a fixed circular stage, the second interference member 61b corresponding to the movable circular stage does not contact the fixed circular stage. Specifically, the first resistance member 61a or the second resistance member 61b is mutually associated and cooperated based on the elastic resistance component 6, and the resistance members can be connected into one, so that during the engagement process between the circular stage 2 and the engaging part 5 on the first platform 1, the resistance members 61 corresponding to each circular stage 2 move elastically synchronously.

[0034] Specifically, Figure 4As shown, in the first embodiment, the movable circular stage corresponding to the circular stage 2 performs rotational movement, and the engaging portion 5 is a circular stepped groove adapted to the circular stage 2, wherein the surface of the circular stage 2 is provided with a rotation scale corresponding to the rotation of the circular stage 2, so as to facilitate the observation of controllable azimuth parameters; the elastic resistance component 6 adopts a spring sheet with elastic deformation performance to be fixedly connected with the first platform 1 in the gap of the first platform 1, and then when one end of the spring sheet is fixed, the other end can be elastically changed based on the fixed end as a fulcrum , and the elastic resistance component 6 is fixed with a second resistance member 61b corresponding to the movable circular stage and a second resistance member 61a corresponding to the fixed circular stage; the first resistance member 61a and the second resistance member 61b adopt a sheet structure, and the portion where the first resistance member 61a and the second resistance member 61b are connected to the circular stage 2 is bent into an arc based on the sheet, and then the first resistance member 61a and the second resistance member 61b are in contact with the circular stage 2 based on the arc contact surface through the hole 8 provided in the clamping part 5. In this embodiment, two resistance members 61 are used for each circular stage 2, which are adapted to the shape of the circular stage 2 and contact the circular stage 2, and can better elastically fix the circular stage.

[0035] In addition, if Figure 5 As shown, based on the application scenario in the first embodiment, in the second embodiment, the elastic abutment assembly 6 uses an elastic member 62 with one end fixedly connected to the first platform 1 in the gap of the first platform 1, and the abutment 61 corresponding to each circular stage 2 is fixedly arranged at the other end of the elastic member 62, and the abutment corresponding to each circular stage 2 contacts the corresponding circular stage 2 engaged in the engaging portion 5 through the hole 8 provided in the engaging portion 5. The elastic member 62 can be, but is not limited to, a spring.

[0036] The elastic resistance assembly 6 provided with the first resistance member 61a and the second resistance member 61b can be an integrally formed device, or a device formed by connecting and assembling various components. Furthermore, due to the elastic deformation performance of the spring sheet, during the connection between the circular stage 2 and the first platform 1, that is, during the engagement between the circular stage 2 and the engaging portion 5, the first resistance member 61a or the second resistance member 61b is subjected to the resistance contact of the circular stage 2, and then based on the elastic deformation and integrity of the spring sheet, the first resistance member 61a and the second resistance member 61b are elastically moved synchronously.

[0037] Specifically, the elastic resistance component 6 is in elastic contact with the circular stage 2 based on the engaging portion 5. When the circular stage 2 is a movable circular stage or a fixed circular stage, the elastic resistance component 6 elastically fixes the circular stage through the first resistance member 61a or the second resistance member 61b as follows:

[0038] Based on the engaging portion 5 provided on the first platform 1, when the circular stage 2 is a fixed circular stage, the fixed circular stage contacts the first resistance member 61a extending through the hole 8 at the first level of the stepped groove of the engaging portion 5. Under the squeezing of the fixed circular stage, the first resistance member 61a1 moves with the first resistance member 61a in the gap provided on the first platform 1 based on the elasticity of the elastic resistance member 6. Then, based on the elasticity of the elastic resistance member 61, the fixed circular stage is squeezed by the elastic resistance member 6 through the rebound force of the first resistance member 61a, so that the fixed circular stage cannot move relative to the first platform 1, thereby completing the installation of the fixed circular stage; Figure 1 As shown, based on the position where the edge of the circular stage 2 is exposed at the edge of the surface of the first platform 1, the circular stage 2 can be disassembled relative to the first platform 1 under the elastic deformation of the elastic resistance component 6. The fixed circular stage does not include movable parts, and can adopt a flat plate structure, specifically, it can adopt an opaque material or a transparent glass material, etc.;

[0039] When the circular stage 2 is a movable circular stage, the movable circular stage is slidably matched with the first platform 1 based on the second sliding guide mechanism 23. Figure 6 As shown, the movable circular stage includes a moving part, a fixed part, and a second sliding guide assembly, wherein the second sliding guide assembly is arranged between the moving part and the fixed part, so that the sliding part and the fixed part slide relative to each other; specifically, based on the rotating movement of the movable circular stage, as shown in FIG. Figure 6 As shown, the movable part adopts a rotating inner ring 21, the fixed part adopts a rotating outer ring 22, and the second sliding guide component is arranged between the rotating inner ring 21 and the rotating outer ring 22; in the process of the engagement between the movable circular stage and the engaging portion 5, the rotating outer ring 22 of the movable circular stage contacts the second resistance member 61b extending through the hole 8 at the next layer of the first layer in the stepped groove of the engaging portion 5, and then the rotating outer ring 22 is squeezed by the elastic resistance component 6 through the rebound force of the second resistance member 61b, so that the rotating outer ring 22 is fixed and cannot move relative to the first platform 1. When the rotating outer ring 22 is fixed, based on the second sliding guide component, the rotating inner ring 21 can move relative to the rotating outer ring 22, thereby completing the installation of the movable circular stage; as shown Figure 1 As shown, based on the position where the edge of the circular stage 2 is exposed at the edge of the surface of the first platform 1, the circular stage 2 can be disassembled relative to the first platform 1 under the elastic deformation of the elastic abutment component 6.

[0040] Furthermore, based on the rigidity requirement of the elastic abutment component 6 in the present solution, a material with relatively strong rigidity needs to be used. The elastic abutment component 6 can be made of a material with relatively strong rigidity such as 65Mn or tin-phosphor bronze.

[0041] In addition, if Figure 2 , Figure 3 As shown, a platform device capable of replacing multiple loading platforms constructed in the present scheme also includes a second platform 3 and a platform base plate 4 which are sequentially stacked with the first platform 1. The first platform 1 slides with the second platform 3 based on a first sliding guide mechanism 7; the second platform 3 slides with the platform base plate 4 in a direction perpendicular to the sliding trajectory of the first platform 1 based on the sliding guide mechanism.

[0042] The first sliding guide mechanism 7 and the second sliding guide mechanism 23 in this solution are collectively referred to as sliding guide mechanisms. Figure 7 As shown, one embodiment of the sliding guide mechanism is specifically: it includes a guide rail member and a rolling member, wherein the guide rail member includes a plurality of round steel wires a, and the rolling member includes a plurality of steel balls b, and the plurality of round steel wires a are arranged around the steel balls b to form a guide rail for the steel balls b to roll. Specifically, four round steel wires a are used to form a rectangular guide rail, and the plurality of steel balls b are in the rectangular guide rail between the four round steel wires a; in the first sliding guide mechanism 7, the four round steel wires a are in a straight line based on the sliding direction of the platform, forming a linear guide rail; in the second sliding guide mechanism 23, the four round steel wires a form a circle, which is convenient for the circular loading platform 2 to rotate and slide.

[0043] like Figure 8 As shown, another embodiment of the sliding guide mechanism is as follows: the guide rail member includes four triangular guide rails c, the rolling member includes cross rollers d, and a cross roller retainer, the four triangular guide rails c are cut into right triangles with the same structural dimensions, and the hypotenuses of the four triangles cooperate to form a sliding guide rail for the cross roller d. In the first sliding guide mechanism 7, the four triangular guide rails c and the cross roller retainer are in a straight line based on the sliding direction of the platform, and the four triangular guide rails c constitute a linear guide rail; in the second sliding guide mechanism 23, the four triangular guide rails c constitute a circular guide rail, which is convenient for the circular stage 2 to rotate and slide, and the cross roller retainer is in a corresponding arc based on the rotation of the circular stage 2.

[0044] The above two sliding guide mechanism embodiments can reduce the size of the sliding guide mechanism, thereby reducing the volume of the platform device, making the structure more streamlined. In addition to the above embodiments, the second sliding guide mechanism 23 can also use other bearings to achieve sliding fit between the two bodies.

[0045] The utility model designs a platform device that can replace multiple stages, including an elastic resistance component 6, which is elastically fixed and matched with the circular stage 2 on the first platform 1 through one of the first resistance member 61a and the second resistance member 61b. The circular stage 2 can be rotated and moved based on the elastic resistance component 6, so that the object to be measured on the measuring platform can be rotated with the circular stage 2, which solves the problem of multi-directional observation of the object to be measured. In addition, the movable circular stage is arranged to rotate and move, and the center of the circular stage 2 remains unchanged, avoiding the problem that the position of the object to be measured placed near the center of the measuring platform changes greatly with the rotation of the measuring platform, and facilitating the observation of the microscope under the rotation of the circular stage 2. In addition, the platform device designed in this scheme can be suitable for the replacement between the movable circular stage and the fixed circular stage based on the designed elastic resistance component 6, and can be suitable for various needs of the measuring platform.

[0046] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The above are only preferred embodiments of the utility model, but do not limit the patent scope of the utility model.
