Description

Technical Field

[0001] This invention relates to the field of guiding equipment technology, and in particular to a two-degree-of-freedom self-resetting guiding device. Background Technology

[0002] During the docking guidance process, the sample is transferred to the next level through the sample delivery device. This transfer process is achieved by the guide cup. However, the sample delivery device will generate a certain positional deviation and attitude angle during the sample delivery process, which requires the guide mechanism to have a floating function.

[0003] In existing technologies, the guiding mechanism is rigid and cannot float. Therefore, it is impossible to simultaneously meet the requirements of floating and self-resetting, resulting in the inability to achieve docking guidance under the aforementioned working conditions when using the guiding mechanism in the existing technology for sample delivery.

[0004] Therefore, the aforementioned technical issues still need to be addressed. Summary of the Invention

Without further limitations, an element defined by the phrase “comprising…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0065] This invention provides a two-degree-of-freedom self-resetting guide device, combined with... Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The two-degree-of-freedom self-resetting guide device includes a guide cup 1, a protruding assembly 2, a mounting assembly 5, a first connector 4, a second connector 6, and an elastic element 3. The protruding assemblies 2 are evenly distributed on the outer side wall of the guide cup 1. The mounting assemblies 5 are connected to each protruding assembly 2. The first connector 4 is longitudinally inserted into the mounting assembly 5 on the side away from the guide cup 1. The second connector 6 is longitudinally inserted into the protruding assembly 2. The elastic element 3 has one end connected to the surface of the first connector 4 near the second connector 6, and the other end connected to the surface of the second connector 6 near the first connector 4. A first gap 7 is provided between the outer side wall of the guide cup 1 and the end of the mounting assembly 5 near the guide cup 1. A reset space 31 is formed between the protruding assemblies 2 and the mounting assemblies 5.

[0066] In this embodiment, the first connector 4 is inserted into the mounting assembly 5, and the second connector 6 is inserted into the protruding assembly 2. An elastic element 3 connects the first connector 4 and the second connector 6. The elastic element 3 stretches and retracts within the reset space 31, causing the protruding assembly 2 on the guide cup 1 to move in a plane within the mounting assembly 5. The protruding assembly 2 drives the guide cup 1 to move synchronously in the plane. Simultaneously, during the retraction process, a first gap 7 is provided between the outer wall of the guide cup 1 and the end of the mounting assembly 5 through the elastic element 3. This allows the guide cup 1 to flexibly float within the range between the mounting assemblies 5, thereby simultaneously satisfying the requirements of floating and self-resetting, enabling the guide cup 1 to achieve docking guidance under this working condition during sample delivery.

[0067] In a specific embodiment, such as Figure 2As shown, the protrusion assembly 2 includes a first protruding wall 21, a second protruding wall 23, a third protruding wall 25, a fourth protruding wall, a first recess 24, and a hole assembly 22. The first protruding wall 21 is vertically connected to the outer wall of the guide cup 1. The second protruding wall 23 is vertically connected to the outer wall of the guide cup 1 near the ground and is parallel to the first protruding wall 21. The third protruding wall 25 is connected to one end of both the first and second protruding walls 21 and is vertically connected to the outer wall of the guide cup 1. The fourth protruding wall is connected to the other end of both the first and second protruding walls 21 and is vertically connected to the outer wall of the guide cup 1. The first recess 24 is formed by the guide cup 1, the first protruding wall 21, the second protruding wall 23, the third protruding wall 25, and the fourth protruding wall. The hole assembly 22 is disposed on the first and second protruding walls 21 and 23. The length of the third protruding wall 25 is the same as the length of the fourth protruding wall, the length of the third protruding wall 25 is less than the length of the first protruding wall 21, and the length of the first protruding wall 21 is the same as the length of the second protruding wall 23.

[0068] In this embodiment, the second connector 6 is simultaneously inserted into the hole assembly 22, so that one end of the elastic member 3 is connected to the second connector 6 within the first recess 24. This causes the protruding assembly 2 to undergo horizontal displacement in the x and y directions under the action of the elastic member 3, thereby causing the guide cup 1 to undergo horizontal displacement in the x and y directions simultaneously.

[0069] In a specific embodiment, such as Figure 2 As shown, the hole assembly 22 includes a second recess 221 and a first through hole 222. The second recess 221 is disposed on the outer surface of the first protruding wall 21 near the side of the second protruding wall 23. The first through hole 222 penetrates the second protruding wall 23, and the radial extension line of the center of the first through hole 222 forms a straight line with the radial extension line of the center of the first recess 24.

[0070] In this embodiment, a straight line is formed between the radial extension line of the center of the first through hole 222 and the radial extension line of the center of the first recess 24. The second connector 6 passes through the first through hole 222 and is inserted into the second recess 221, so that the second connector 6 is fixed on the first protruding wall 21 and the second protruding wall 23.

[0071] To more stably fix the second connector 6 to the first protruding wall 21 and the second protruding wall 23, in a specific embodiment, such as... Figure 2 As shown, the diameter of the first through hole 222 is larger than the diameter of the first recess 24.

[0072] In a specific embodiment, such as Figure 3As shown, the mounting assembly 5 includes a first mounting wall 51, a second mounting wall 54, a third mounting wall 58, a fourth mounting wall 53, a second through hole 55, a first connector 56, a third through hole 52, and a fourth through hole 57. The first mounting wall 51 is slidably connected to the outer surface of a first protruding wall 21 on the side away from the ground. The second mounting wall 54 is slidably connected to the outer surface of a second protruding wall 23 on the side near the ground. The third mounting wall 58 is connected to one end of the first mounting wall 51 and the second mounting wall 54. The fourth mounting wall 53 is connected to the other end of the first mounting wall 51 and the second mounting wall 54. The second through hole 55 is formed by the first mounting wall 51, the second mounting wall 54, the third mounting wall 58, and the fourth mounting wall 53. The first connector 56 is simultaneously connected to the second mounting wall 54, the third mounting wall 58, and the fourth mounting wall 53 on the side away from the guide cup 1. The third through holes 52 are evenly distributed on the first mounting wall 51 and are inserted into the first connector 4. The fourth through hole 57 is evenly disposed on the second mounting wall 54 and is inserted into the first plug-in 4.

[0073] In this embodiment, the first connector 4 passes through both the third through hole 52 on the first mounting wall 51 and the fourth through hole 57 on the second mounting wall 54, so that the other end of the elastic member 3 is connected to the first connector 4 in the reset space 31. This causes the protruding assembly 2 to move horizontally in the x and y directions under the action of the elastic member 3, thereby causing the guide cup 1 to move horizontally in the x and y directions simultaneously.

[0074] The first protruding wall 21, the second protruding wall 23, the third protruding wall 25, and the fourth protruding wall move within the second through hole 55, and the outer surfaces of the first protruding wall 21 and the second protruding wall 23 move on the surface of the second through hole 55. A first sliding gap is left between the third protruding wall 25 and the third mounting wall 58, and a second sliding gap is left between the fourth protruding wall and the fourth mounting wall 53. The width of the first sliding gap is the same as the width of the second sliding gap, thereby giving the first protruding wall 21, the second protruding wall 23, the third protruding wall 25, and the fourth protruding wall rigidity in the Z direction, thus achieving limiting in the Z direction.

[0075] In a specific embodiment, the same first connector 4 is simultaneously inserted between the longitudinally adjacent third through hole 52 and fourth through hole 57.

[0076] In a specific embodiment, combined with Figure 3 and Figure 4An arc-shaped third recess 511 is provided at the end of the first mounting wall 51 near the guide cup 1, and an arc-shaped fourth recess is provided at the end of the second mounting wall 54 near the guide cup 1. The curvature of the third recess 511 is the same as the curvature of the outer wall of the guide cup 1, and the curvature of the third recess 511 is the same as the curvature of the fourth recess.

[0077] In this embodiment, the curvature of the third recess 511 and the fourth recess is the same as the curvature of the outer wall of the guide cup 1, which is beneficial for the first mounting wall 51 and the second mounting wall 54 to cooperate with the outer wall of the guide cup 1 during movement, and to prevent the first mounting wall 51 and the second mounting wall 54 from hitting the outer wall of the guide cup 1.

[0078] In a specific embodiment, such as Figure 3 As shown, the end of the first connector 56 away from the second mounting wall 54 is vertically connected to the second connector 8, and the second connector 8 is uniformly provided with fifth through holes 81.

[0079] In this embodiment, the second connector 8 is fixed to the target platform or target device by passing a connector through the fifth through hole 81, thereby fixing each mounting component 5. Furthermore, the guide cup 1 is allowed to flexibly float within the range between each mounting component 5, thus simultaneously satisfying the requirements of floating and self-resetting.

[0080] To further achieve stability during the flexible floating process of the guide cup 1 within the range of each mounting component 5, in a specific embodiment, in combination with Figure 3 and Figure 6 A support member 10 is provided between the outer surface of the first connector 56 near the guide cup 1 and the outer surface of the second mounting wall 54 near the ground.

[0081] In order to achieve guidance of guide cup 1 within the target error range, in a specific embodiment, in combination with Figure 2 and Figure 6 The upper part of the guide cup 1 is provided with a guide part 11, and the angle between the outer side wall of the guide part 11 and the axial direction of the center of the guide cup 1 is 15° to 20°.

[0082] In this invention, as a two-degree-of-freedom self-resetting guide mechanism, three protruding components 2 are provided on the outer wall of the guide cup 1. Each protruding component 2 is slidably connected to a mounting component 5. A first insert 4 is inserted into the mounting component 5, and a second insert 6 is inserted into the protruding component 2. An elastic element 3 connects the first insert 4 and the second insert 6. That is, the three elastic elements 3 achieve the two-degree-of-freedom floating and self-resetting function of the guide cup 1 in the x and y directions. By replacing the elastic elements 3, the stiffness can be varied and the magnitude of the restoring force adjusted, achieving flexible guidance and meeting the engineering requirements where the sample delivery device 9 may experience certain deviations during docking guidance. Furthermore, the gap amount of each first gap 7 is the same, used to limit the stretching amount of the elastic element 3, ensuring that the elastic element 3 does not undergo excessive deformation. The size of the gap is equal to the floating amount of the guide cup 1.

[0083] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
