In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] The specific embodiments of the present application will be described in detail below in conjunction with the drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present application, and are not used to limit the present application.

[0033] The first aspect of the embodiments of the present application is to provide a floating connection assembly, such as Figures 1 to 3As shown, the floating connection assembly comprises a mounting base 1, an elastic member 2 and a floating block 3; the mounting base 1 has a mounting cavity 11, one end of the floating block 3 is limited in the mounting cavity 11, the other end of the floating block 3 extends out of the mounting cavity 11, the floating block 3 has freedom of movement in the axial direction and the radial direction relative to the mounting cavity 11; the elastic member 2 is arranged in the mounting cavity 11, the elastic member 2 is matched with the bottom surface of the mounting cavity 11 and the floating block 3 at the two ends in the axial direction of the mounting cavity 11, and the end surface of the floating block 3 in the mounting cavity 11 is abutted against the top surface of the mounting cavity 11 under the action of the elastic member 2.

[0034] In use of the floating connection assembly, as shown in Figure 3 and Figure 4 , the mounting base 1 can be connected with the bottom plate 6, and the floating block 3 can be connected with the top plate 5, after the connection, the docking device can be used for docking with a probe table, and the bottom plate 6, the floating block 3 and the top plate 5 are arranged in sequence from top to bottom, at this time, under the action of the gravity of the top plate 5 and the elastic member 2, the end of the floating block 3 in the mounting cavity 11 is abutted against the top surface of the mounting cavity 11.

[0035] In the docking process, if there is a deviation between the docking device and the probe table in the X direction and the Y direction, the probe table will cause resistance to the movement of the bottom plate 6, so that the top plate 5 compresses the elastic member 2 upward through the floating block 3, the end surface of the floating block 3 cancels the abutment with the top surface of the mounting cavity 11, the floating block generates a certain radial floating gap to compensate for the above deviation, meets the docking requirements of the top plate 5, reduces the impact and wear at the docking position, and at the same time, since the floating block 3 can float in the axial direction, it can also buffer a certain docking impact force.

[0036] The floating connection assembly can avoid the rigid connection between the top plate and the bottom plate, in the docking process, the floating block 3 can float in the axial direction and the radial direction of the mounting cavity 11, so as to compensate for the deviation between the docking device and the probe table in the X direction and the Y direction, and at the same time, buffer a certain docking impact force in the axial direction of the mounting cavity 11, that is, in the Z direction.

[0037] It can be understood that the radial direction of the mounting cavity 11 is parallel to or coincides with the plane in which the X direction and the Y direction are located.

[0038] In the initial stage of the docking of the top plate 5 and the probe table, there is a certain accuracy requirement for the positioning of the top plate 5, therefore, in the optional embodiment, the top surface of the mounting cavity 11 has an inner limiting surface, the end surface of the floating block 3 in the mounting cavity 11 has an outer limiting surface matched with the inner limiting surface, and the outer limiting surface of the floating block 3 is abutted against the inner limiting surface under the action of the elastic member 2. The inner limiting surface can limit the position of the floating block 3 relative to the mounting cavity 11, so that in the initial stage of the docking, the position of the floating block 3 is relatively stable, so as to ensure that the top plate 5 does not shake, and ensure the positioning accuracy of the top plate 5.

[0039] Of course, in other alternative embodiments, the inner limiting surface and the outer limiting surface can not be provided.

[0040] The inner limiting surface can have various shapes, such as a conical shape, a hemispherical shape, or a stepped shape.

[0041] In an alternative embodiment, as shown in Figure 3 the top surface of the mounting cavity 11 has a first conical surface 121, and the floating block 3 has a second conical surface 321 that cooperates with the first conical surface 121, and the second conical surface 321 of the floating block 3 is used to abut against the first conical surface 121 under the action of the elastic member 2.

[0042] In use, under the action of the gravity of the top plate 5 and the elastic member 2, the second conical surface 321 of the floating block 3 abuts against the first conical surface 121, thereby limiting the floating block 3 at one end of the mounting seat 1, so that the top plate 5 does not shake at the initial stage of docking, and the positioning accuracy of the top plate 5 is ensured.

[0043] In an alternative embodiment, as shown in Figure 3 the floating block 3 extends from the first end of the mounting cavity 11, and the first conical surface 121 gradually decreases in circumferential size in a direction gradually approaching the first end.

[0044] The above arrangement is more convenient for processing the floating block 3. If the first conical surface 121 gradually increases in circumferential size in a direction gradually approaching the first end, then the middle of the end surface of the floating block 3 needs to be concave with a second conical surface 321, so that the second conical surface 321 can abut against the first conical surface 121 under the action of the elastic member 2, and this is not convenient for processing the floating block.

[0045] In an alternative embodiment, as shown in Figure 3 the floating block 3 includes a limiting portion 31, a centering portion 32, and a connecting portion 33 connected in sequence, wherein:

[0046] The limiting portion 31 and the centering portion 32 are located in the mounting cavity 11, the outer portion of the limiting portion 31 is sleeved with the elastic member 2 to limit the end portion of the elastic member 2 in the radial direction of the mounting cavity 11, the elastic member 2 abuts against the end surface of the centering portion 32 close to the limiting portion 31 to limit the end portion of the elastic member 2 in the axial direction of the mounting cavity 11, and the lower end surface of the centering portion can abut against the top surface of the mounting cavity 11 under the action of the elastic member 2;

[0047] The connecting portion 33 at least partially extends out of the mounting cavity 11, and the portion of the connecting portion 33 extending out of the mounting cavity 11 is used to connect with the top plate 5.

[0048] The above floating block 3 has a simple structure, which not only can limit the end portion of the elastic member 2, but also is convenient for connecting with the top plate 5.

[0049] In an optional embodiment, the centering portion 32 has a second tapered surface 321 on the side away from the elastic member 2, and the second tapered surface 321 cooperates with the first tapered surface 121 of the mounting cavity 11.

[0050] In an optional embodiment, the floating connection assembly is cut along any plane along the axis of the mounting cavity 11 to form a cutting surface, as shown in Figure 3 In the cutting surface, the radial dimension of the centering portion 32 is smaller than the radial dimension of the end of the first tapered surface 121 close to the bottom surface of the mounting cavity 11, and the radial dimension of the connecting portion 33 is smaller than the radial dimension of the end of the first tapered surface 121 away from the bottom surface of the mounting cavity 11, so that when the end surface of the floating block 3 in the mounting cavity 11 is removed from abutting the top end of the mounting cavity 11, there is a gap between the floating block 3 and the mounting cavity 11, thereby allowing the floating block 3 to have freedom in axial and radial directions relative to the mounting cavity 11.

[0051] In an optional embodiment, the centering portion 32 has a shape similar to a circular truncated cone, and the outer surface has a second tapered surface 321; the limiting portion 31 and the connecting portion 33 have a cylindrical shape, which is convenient for machining. The outer diameter of the limiting portion 31 is smaller than the outer diameter of the end of the centering portion 32 close to the limiting portion 31, so as to axially limit the end of the elastic member 2.

[0052] The elastic member 2 can be a spring, a spring sheet, an elastic pad, etc.

[0053] Preferably, the elastic member 2 is a coil spring, and the coil spring is in a force storage state.

[0054] Since different center clamps 7 are required for different needle card modules, the gravity of different center clamps 7 cannot be ignored, and therefore, in an optional embodiment, as shown in Figure 3 The mounting seat 1 is provided with an adjusting assembly 4, which is at least partially located in the mounting cavity 11, and cooperates with the end of the elastic member 2 away from the floating block 3. The adjusting assembly 4 can move in the axial direction of the mounting cavity 11 to adjust the force applied by the elastic member 2 to the floating block 3 (i.e., to adjust the pre-tightening force of the elastic member 2), thereby reducing the change in the force during docking due to the change in the weight of the center clamp 7, and improving the service life of the equipment.

[0055] In use, the compression amount of the elastic member 2 can be controlled by adjusting the adjusting assembly 4, because the force during the abutting is equal to the elastic force of the elastic member 2 given to the top plate 5 through the floating block 3 plus the weight of the top plate and the weight of the center clamp 7. For example, when the weight of the center clamp 7 increases, the compression amount of the elastic member 2 needs to be reduced, so as to reduce the elastic force of the elastic member 2 given to the top plate 5 through the floating block 3, so that the force during the abutting only causes a small floating or no change, reduces the change of the force during the abutting caused by the change of the weight of the center clamp 7, and improves the service life of the equipment.

[0056] It should be noted that any structure capable of adjusting the force of the elastic member 2 given to the floating block 3 can be the adjusting assembly 4 mentioned in the above embodiments. For example, the adjusting assembly 4 includes a limiting seat screwed into the mounting cavity 11, and the limiting seat adjusts the axial position in the mounting cavity 11 by rotating itself.

[0057] For another example, as shown in Figure 3 , the adjusting assembly 4 includes an adjusting member 41 and a movable seat 42, the movable seat 42 is in sliding fit with the inner wall of the mounting cavity 11 in the axial direction of the mounting cavity 11, the elastic member 2 is arranged between the movable seat 42 and the floating block 3, the adjusting member 41 is movably connected with the mounting seat 1, one end of the adjusting member 41 extends into the mounting cavity 11 and is in fit with the movable seat 42, and the adjusting member 41 is used to drive the movable seat 42 to move in the axial direction of the mounting cavity 11.

[0058] In use, the adjusting member 41 is movable relative to the mounting seat, and in the moving process, the adjusting member 41 drives the movable seat 42 to move axially relative to the mounting cavity 11, so as to increase or reduce the extrusion of the elastic member 2 by the movable seat 42.

[0059] In an optional embodiment, the adjusting member 41 is in screw fit with the mounting seat 1, and the rotation axis of the adjusting member 41 is parallel to or coincides with the axis of the mounting cavity 11.

[0060] The above arrangement facilitates the movement of the adjusting member 41, and in use, only the rotation of the adjusting member 41 is needed.

[0061] In an optional embodiment, the end of the adjusting member 41 extending into the mounting cavity 11 abuts against the movable seat 42.

[0062] When the adjusting member 41 increases the length extending into the mounting cavity 11, the adjusting member 41 pushes the movable seat 42 to move downward to extrude the elastic member 2; when the adjusting member 41 shortens the length extending into the mounting cavity 11, the adjusting member 41 moves upward, and the movable seat 42 moves upward under the elastic force of the elastic member 2.

[0063] In an optional embodiment, as shown in Figure 1As described above, in order to facilitate the installation of the elastic member 2 and the floating block 3, the mounting seat 1 includes an outer shell 12 and an end plate 13. The inner end surface of one end of the outer shell 12 is against the floating block 3, and the other end of the outer shell 12 is detachably connected to the end plate 13. The end plate 13 and the outer shell 12 enclose a mounting cavity 11, and the adjustment member 41 is movably arranged on the end plate 13.

[0064] When the elastic member 2 and the floating block 3 need to be installed, the end plate 13 can be removed, the elastic member 2 and the floating block 3 can be placed in the housing 12 , and then the end plate 13 can be connected to the housing 12 .

[0065] Specifically, the inner end surface of the housing 12 that contacts the floating block 3 may have a first tapered surface 121 .

[0066] When the adjustment assembly 4 is provided, the adjustment member 41 in the adjustment assembly 4 can be movably connected to the end plate 13 . The above arrangement facilitates the installation of the adjustment assembly 4 .

[0067] The second embodiment of the present invention is to provide a docking device, such as Figure 4 As shown, the docking device provided by the embodiment of the second aspect of the present invention includes a top plate 5, a bottom plate 6, a central clamp 7 and the above-mentioned floating connection assembly.

[0068] When in use, the bottom plate 6 is connected to the mounting seat 1, the top plate 5 is connected to the floating block 3, and the center clamp 7 is installed on the top plate 5. The floating block 3 can compensate for the deviation between the docking device and the probe station in the X and Y directions, and at the same time can buffer a certain docking impact along the Z direction, thereby reducing the requirements for the processing of the docking device and the docking accuracy.

[0069] Specifically, if Figure 1 and Figure 3 As shown, a first connecting hole 122 is provided on the outer shell 12 of the mounting base 1, and a screw or other connecting member can pass through the bottom plate 6 and connect to the first connecting hole 122 to realize the connection between the mounting base 1 and the bottom plate 6; a second connecting hole 331 is provided on the connecting portion 33 of the floating block 3, and a screw or other connecting member can pass through the top plate 5 and connect to the second connecting hole 331 to realize the connection between the mounting base 1 and the top plate 5.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
