Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of semiconductor equipment, and in particular to a heavy-load displacement adjustment mechanism. Background Art
[0002] In the field of semiconductor chip processing, the smaller the chip's feature size, the higher the chip's integration and the better the performance; the smaller the chip, the more precise the line lithography, and the higher the requirements for the lighting lens; the lighting lens ensures line precision by increasing the magnification, which greatly increases the size and weight of the lighting lens.
[0003] In the prior art, a heavy-duty adjustment mechanism is usually used to achieve adjustment of the fixed position of the lens, and the adjustment directions are at least two mutually perpendicular directions located in the same horizontal plane, specifically a first direction and a second direction, the first direction corresponds to the y direction, and the second direction corresponds to the x direction; since the weight of the lighting lens is greatly increased, when the position of the lighting lens is adjusted, the connection parts, drive structure and other positions of the heavy-duty adjustment mechanism are prone to jamming and mechanical jamming, making it difficult to achieve precise displacement of the heavy-loaded lighting lens, affecting the quality of the dimensional adjustment work of the lighting lens. Summary of the Invention
[0004] In view of this, the present invention provides a heavy-load displacement adjustment mechanism to solve the problem that it is difficult to achieve precise position adjustment of a heavy-loaded lighting lens on the adjustment mechanism.
[0005] The present invention provides a heavy-load displacement adjustment mechanism, comprising: a first plate body and a second plate body that are at least partially overlapped and slidably connected in sequence; a first floating part, fixed to the first plate body, the first floating part having a first pressing member, and the pressing force of the first pressing member is adjustable; a first driving member, fixed to the second plate body; a first connecting part, connected to the first driving member; the first connecting part is pressed by the first pressing member and floatingly connected to the first plate body; in a normal state, the first connecting part is pressed and fixed to the first plate body by the first pressing member, and the first driving member is suitable for driving the first plate body to move; in a first abnormal state, the first pressing member adjusts the pressing force acting on the first connecting part, which is suitable for loosening or re-tightening the first connecting part and the first plate body.
[0006] Beneficial effects: The floating part floats and presses the connecting part against the plate body, thereby making the driving part float and connected to the plate body. The floating part can change the floating pressing force acting on the connecting part, thereby solving the jamming and mechanical jamming phenomena generated during the movement by adding or subtracting pressure, and increasing the pressure to adjust to avoid the problem of looseness at the connecting part and thus reducing the transmission sensitivity. The precision of heavy-load structures such as lighting lenses during displacement adjustment is always guaranteed, and the purpose of heavy-load precision adjustment is achieved, taking into account the heavy-load requirements and the requirements of high-precision precision displacement adjustment, achieving both, and having a strong use effect. In addition, the floating part provides an initial preload force acting on the connecting part, effectively eliminating the mechanical clearance error, reducing the drive displacement return amount, and driving the precision jump.
[0007] Beneficial effects: The connecting part is composed of a release part and a driving part, so that the connecting part has an additional release function. The release part is floated and pressed to the plate body by the floating part in normal use. When an emergency situation occurs and the floating part cannot be adjusted and restored, the release part will withdraw from the floating part and the plate body in time, and then directly disconnect the connection between the driving part and the plate body to prevent structural damage. The emergency release mechanism can quickly cut off the connection between the driving end and the transmission end, effectively eliminating system risks.
[0008] Beneficial effects: The first clamping member cooperates with the fourth driving member, and the second clamping member cooperates with the third driving member. By linking the force-applying elements with the same force direction, the control accuracy of the mechanism is improved, and the safety of the system operation is improved, to prevent any single force-applying element from losing control or insufficient force to cause a failure risk; at the same time, a buckle and a compensation mechanism are provided in the linkage mechanism, and the buckle controls the connection and disconnection of the linkage mechanism, so that the clamping member and the driving member work independently of each other under normal conditions, and are linked when one of them fails.

[0042] The following combination Figures 1 to 11 , describing embodiments of the present invention.
[0043] In the first aspect, an embodiment of the present invention provides a heavy-load displacement adjustment mechanism, comprising a first plate body 1, a second plate body 2 and a third plate body 3 that are at least partially overlapped and slidably connected in sequence, and also comprising a first driving member 5 and a second driving member 8 for driving the movement of the plate body, and also comprising a first connecting portion 6 and a second connecting portion 9 for connecting the driving member to the plate body and for emergency disengagement, and also comprising a first floating portion 4 and a second floating portion 7 for floatingly connecting the connecting portion to the plate body; in this embodiment, the output shaft of the driving part and the plate body are in a floating connection, and the adjustment structure can solve the jamming and mechanical jamming phenomena generated during the movement by loosening the pressure and increasing the pressure to avoid loosening of the connection part and thus reducing the transmission sensitivity by changing the clamping force at the connection part, thereby ensuring the precision of the heavy-load structure during displacement adjustment at all times and achieving the purpose of heavy-load precision adjustment.
[0044] It should be noted that the connection part is connected to the plate body in a floating manner by means of a compression piece at the floating part. The floating connection can provide a relaxation buffer for the adjustment mechanism during movement and adaptively adjust the jamming and mechanical deadlock phenomena.
[0045] The first connecting portion 6 includes a third driving member 61 and a first disengaging member 62, and the first floating portion 4 includes a first connecting member 42 and a first pressing member 41; the first pressing member 41 is fixed to the first plate body 1 by means of the first connecting member 42; the first disengaging member 62 includes a first large end 621 and a first small end 622, and the size of the first large end 621 in the first direction is larger than the first small end 622; wherein the output shaft of the third driving member 61 is fixed to the first disengaging member 62, and the base of the third driving member 61 is fixed to the output shaft of the first driving member 5. In this embodiment, the first large end The end 621 is arranged close to the base, and the output shaft of the third driving member 61 is arranged parallel to the second direction; when the adjustment mechanism is in normal use, the first clamping member 41 is pressed and abutted against one side end face of the first large end 621 along the first direction, and at the same time, the other side end face of the first large end 621 along the first direction abuts against the first plate body 1, so that the first release member 62 is pressed and connected to the first plate body 1; the clamping force of the first clamping member 41 is adjustable, and the first release member 62 is floatingly pressed against the first plate body 1, and then the first driving member 5 is floatingly connected to the first plate body 1.
[0046] The second connecting portion 9 includes a fourth driving member 91 and a second disengaging member 92, and the second floating portion 7 includes a second connecting member 72 and a second pressing member 71; the second pressing member 71 is fixed to the second plate body 2 by means of the second connecting member 72; the second disengaging member 92 includes a second large end 921 and a second small end 922, and the size of the second large end 921 in the second direction is larger than the second small end 922; wherein the output shaft of the third driving member 61 is fixed to the second disengaging member 92, and the base of the third driving member 61 is fixed to the output shaft of the second driving member 8. In this embodiment, the second large end The end 921 is arranged close to the base, and the output shaft of the fourth driving member 91 is arranged parallel to the first direction; when the adjusting mechanism is in normal use, the second clamping member 71 is pressed and abutted against one side end face of the second large end 921 along the second direction, and at the same time, the other side end face of the second large end 921 along the second direction abuts against the second plate body 2, so that the second release member 92 is pressed and connected to the second plate body 2; the clamping force of the second clamping member 71 is adjustable, and the second release member 92 is floatingly pressed and abutted against the second plate body 2, and then the second driving member 8 is floatingly connected to the second plate body 2.
[0047] Furthermore, the directions of the forces acting on the first clamping member 41 and the fourth driving member 91 are both in the first direction, and the first clamping member 41 and the fourth driving member 91 are linked with each other by means of a mechanical structure; the directions of the forces acting on the second clamping member 71 and the third driving member 61 are both in the second direction, and the second clamping member 71 and the third driving member 61 are linked with each other by means of a mechanical structure; the mechanical structure may be, but is not limited to, a direct connection structure such as a hinge, a slide rail, or a mechanical direct connection; a connection switch and a compensation mechanism are provided in the mechanical structure, and the connection switch may be a fully automatic disengagement connection buckle to automatically control the connection or disconnection of the linkage structure according to actual conditions.
[0048] It should be noted that the adjustment directions of the adjustment mechanism are at least two mutually perpendicular directions located in the same horizontal plane, specifically a first direction and a second direction, wherein the first direction corresponds to the y direction and the second direction corresponds to the x direction.
[0049] It should be noted that the base of the first driving member 5 is fixed to the second plate 2, and the output shaft is floatingly connected to the first plate 1, which is used to drive the first plate 1 to move along the y direction; the base of the second driving member 8 is fixed to the third plate 3, and the output shaft is floatingly connected to the second plate 2, which is used to drive the second plate 2 and the first plate 1 to move along the x direction.
[0050] The specific working process of the heavy-load displacement adjustment mechanism is as follows: on the one hand, during the process of the first plate body 1 performing displacement adjustment along the first direction, i.e., the y direction, due to the heavy weight of the lens, mechanical jamming may occur at the first driving member 5; in the first abnormal state, i.e., when the first driving member 5 has a tendency to produce jamming or mechanical jamming, the first floating portion 4 immediately performs loosening pressure adjustment, reduces the clamping force of the first clamping member 41, reduces the clamping effect on the first large end 621, and loosens the connection between the first driving member 5 and the first plate body 1. The degree of loosening depends on the specific situation. The first driving member 5 obtains a relaxation buffer along the first direction, and uses the relaxation buffer to eliminate or alleviate the jamming and mechanical jamming phenomenon, and then slowly increases the pressure of the first clamping member 41, so that the first clamping member 41 is re-pressed to the first large end 621, and the displacement adjustment work along the first direction and the y direction is performed again; on the other hand, when the second plate body 2 drives the second plate body 2 to perform displacement adjustment along the first direction, i.e., During the x-direction displacement adjustment, due to the heavy weight of the lens, mechanical jamming may occur at the second driving member 8. When the second driving member 8 tends to produce jamming or mechanical jamming, the second floating part 7 is immediately loosened and adjusted to reduce the clamping force of the second clamping member 71, reduce the clamping effect on the second large end 921, and loosen the connection between the second driving member 8 and the second plate 2. The degree of loosening depends on the specific situation. The second driving member 8 obtains a relaxation buffer along the second direction, and uses the relaxation buffer to eliminate or alleviate the jamming and mechanical jamming. Then, the pressure of the second clamping member 71 is slowly increased, so that the second clamping member 71 is re-pressed to the second large end 921, and the displacement adjustment work along the second direction and the x-direction is performed again; on the other hand, the floating part is pre-pressed at the connection part, so that the connection part between the driving member and the plate body obtains an initial pre-tightening force, which can effectively eliminate mechanical clearance error, reduce the drive displacement return amount, and mechanical precision jump.
[0051] Furthermore, when the connection between the driving part and the plate body is slightly loose, the clamping part at the floating part can promptly increase the clamping force acting on the disengaging part, so that the driving part and the plate body always maintain a stable connection, prevent the transmission sensitivity from decreasing, and ensure the displacement accuracy.
[0052] It should be noted that a pressure sensor is provided at the pressing member for detecting the pressure relationship between the pressing member and the release member in real time, and a displacement sensor is provided at the plate body for detecting the movement displacement state of the plate body in real time.
[0053] The working process of the disengaging structure of the heavy-load displacement adjustment mechanism is as follows: in the second abnormal state, that is, when an emergency risk situation occurs, the disengaging structure is required to disconnect the connection between the driving member and the plate body; on the one hand, when a risk situation is encountered during the displacement adjustment work along the first direction, the third driving member 61 is started, the output shaft of the third driving member 61 contracts, and drives the first disengaging member 62 to retreat from the first plate body 1 and the first clamping member 41, the first large end 621 is disengaged from the floating connection with the first plate body 1 and the first clamping member 41, and the first small end 622 is placed between the first clamping member 41 and the first plate body 1, thereby disconnecting the first driving member 5 from the first plate body 1 and the first clamping member 41. The connection of the plate body 1, the first plate body 1 is in a free state, and the emergency escape processing work is completed; on the other hand, when a risk situation is encountered during the displacement adjustment work along the second direction, the fourth driving member 91 is started, the output shaft of the fourth driving member 91 contracts, and drives the second escape member 92 to retreat from the second plate body 2 and the second clamping member 71, the second large end 921 is disengaged from the floating connection with the second plate body 2 and the second clamping member 71, and the second small end 922 is placed in a gap between the second clamping member 71 and the second plate body 2, thereby disconnecting the second driving member 8 from the second plate body 2, and the second plate body 2 is in a free state, completing the emergency escape processing work.
[0054] It should be noted that the first abnormal state is a state that can be adaptively restored through the floating connection, such as mechanism jamming or mechanical deadlock; the second abnormal state is other working conditions encountered by the adjustment mechanism during the displacement adjustment process that cannot be automatically adjusted and restored through the floating connection, and requires manual or other methods to correct and reset.
[0055] The working process of the linkage structure of the heavy-load displacement adjustment mechanism is as follows: the pressing member and the disengagement drive member are linked by means of a mechanical structure to improve the control accuracy of the mechanism and the safety of the system operation, and prevent the risk of failure caused by any single force-applying element losing control or insufficient force; under normal working conditions, the buckle is disengaged, the linkage structure is disconnected, the first pressing member 41 and the fourth drive member 91 operate independently, and the second pressing member 71 and the third drive member 61 operate independently, and each independently undertakes the corresponding driving work; when an emergency occurs, the emergency may be that one of the pressing member and the disengagement drive member is stuck or not working, that is, the special situation where the power of one of the parties in the linkage system is partially or completely failed, the buckle is automatically connected, the pressing member and the disengagement drive member are linked, and then auxiliary driving or clamping operation is performed on the failed party, and the force in the same direction is increased to the insufficient force or failure point. At the same time, the compensation mechanism can compensate for the pressure transmitted by the pressing member or linkage member on the force-applying party during the linkage process, preventing the linkage from affecting its own working state and ensuring the normal realization of the driving and clamping functions.
[0056] The auxiliary displacement structure of the heavy-load displacement adjustment mechanism is a slide rail, including a first slide rail 10, a second slide rail 11, a third slide rail 14 and a fourth slide rail 15, wherein the first slide rail 10 and the second slide rail 11 are used to realize relative movement between the plates, and the third slide rail 14 and the fourth slide rail 15 are used to assist in the movement of the ejection member; the first slide rail 10 is clamped between the first plate body 1 and the second plate body 2 and is extended along the first direction, and the first slide rail 10 cooperates with the first driving member 5 to realize the sliding of the first plate body 1 relative to the second plate body 2 along the first direction; the second slide rail 11 is clamped between the second plate body 2 and the third plate body 3 and is extended along the second direction, and the second slide rail 11 cooperates with the second driving member 8 to realize the sliding of the second plate body 2 relative to the third plate body 3 along the second direction, and at the same time, the second plate body 2 drives the first plate body 1 to slide synchronously along the second direction; the first slide rail 10 includes a first slideway 101 and a first slider 102, the first slide rail 10 is fixed to a side surface of the second plate body 2 close to the first plate body 1, and a plurality of first sliders 1 02 is slidably connected to the first slide rail 10, wherein one of the first sliders 102 is connected to the first ejecting member 62, and the other first sliders 102 are fixed to the plate surface of the first plate body 1, wherein the first ejecting member 62 and the first slider 102 are connected by means of the third slide rail 14, and the third slide rail 14 is extended along the second direction to ensure the stability of the connection between the first ejecting member 62 and the plate body, and at the same time assist the movement of the first ejecting member 62; the second slide rail 11 includes a second slide 111 and a second slider 112, and the second slide rail 1 1 is fixed to a side surface of the third plate body 3 close to the second plate body 2, and multiple second sliders 112 are slidably connected to the second slide rail 11, one of the second sliders 112 is connected to the second release member 92, and the remaining second sliders 112 are fixed to the plate surface of the second plate body 2. The second release member 92 and the second slider 112 are connected by a fourth slide rail 15. The fourth slide rail 15 extends along the first direction to ensure the stability of the connection between the second release member 92 and the plate body and assist in the movement of the second release member 92.
