[0024] The embodiment of the present disclosure provides a mask adjustment device. Figure 1 and Figure 2 The mask adjustment device comprises two first connecting members 1 and a pair of clamping mechanisms; the first connecting members 1 extend along the second direction Y.

[0025] In some examples, the mask adjustment device further includes two third connecting members 3; the third connecting members 3 extend along the first direction X and are connected to the first connecting member 1 to form a frame. The first direction X and the second direction Y intersect (e.g., are perpendicular). The first connecting member 1, the first connecting member 1 and the second connecting member 2 are structures such as rods, columns, and beams. When in use, one end of the first connecting member 1 can be placed on a workbench or bottom surface.

[0026] The clamping mechanism comprises a second connecting member 2, an adjusting mechanism 6, a top sheet 7 and a distance measuring mechanism.

[0027] The second connecting member 2 extends along the first direction X, and the second connecting member 2 is arranged on the first connecting member 1 .

[0028] In some examples, the two second connectors 2 are located between the two third connectors 3. For example, the second connector 2 is parallel to the third connector 3.

[0029] The second connecting member 2 is arranged on the first connecting member 1, which means that both ends of the second connecting member 2 are respectively connected to the two first connecting members 1. Exemplarily, the second connecting member 2 is fixedly arranged on the first connecting member 1.

[0030] As another example, the second connecting member 2 is movably disposed on the first connecting member 1 and can move along the second direction Y. Thus, the second connecting members 2 of the two clamping mechanisms are moved closer to or farther from each other, so that a pair of clamping mechanisms can clamp masks 8 of different sizes.

[0031] In some examples, the clamping mechanism further includes a moving mechanism and a driving mechanism. The second connecting member 2 is arranged on the first connecting member 1 through the moving mechanism, and the second connecting member 2 moves along the second direction Y. The driving mechanism is arranged on the first connecting member and is connected to the moving mechanism for driving the moving mechanism to move. In this way, the moving mechanism is driven by the driving mechanism so that the second connecting member 2 moves along the second direction Y on the first connecting member 1. The moving mechanism can be a slider and a slide groove, for example, the first connecting member 1 is provided with a slide groove along the second direction Y, and a slider is provided at the end of the second connecting member 2, and the slider can slide in the slide groove. Of course, the moving mechanism can also be a slider and a slide rail, etc. The driving mechanism can be a telescopic mechanism, for example, a telescopic mechanism is installed on the first connecting member 1, and the telescopic mechanism is connected to the slider, which is used to drive the slider to slide in the slide groove. Of course, the driving mechanism can also be a motor, etc.

[0032] In some examples, one end of the second connector 2 is movably connected to one first connector 1 through a moving mechanism and a driving mechanism. The other end of the second connector 2 is movably connected to another first connector 1 through a moving mechanism and a driving mechanism; of course, the other end of the second connector 2 is only movably connected to another first connector 1 through a moving mechanism.

[0033] In some examples, the clamping mechanism further includes a controller, which is electrically connected to the driving mechanism and is used to control the driving mechanism to start or stop. The controller is a conventional structure in the art and will not be described in detail. Of course, the controller can also control the driving mechanism to perform some actions, for example, the controller can control the speed of the driving mechanism to change the moving speed of the second connecting member 2. When the two second connecting members 2 approach each other, the controller controls the driving mechanism so that the speed of the two second connecting members 2 approaching each other is slower to prevent collision.

[0034] The second connecting member 2 has a clamping groove 4. The notches of the clamping grooves 4 of the two second connecting members 2 are opposite to each other along the second direction Y.

[0035] The top sheet 7 is located in the clamping groove 4 and is arranged opposite to the first side wall of the clamping groove 4 along the first direction X. The adjustment mechanism 6 is arranged on the second connecting member 2 and connected to the top sheet 7, and is used to drive the top sheet 7 to move along the first direction X so that the top sheet 7 is close to or away from the first side wall. In this way, the adjustment mechanism 6 moves the top sheet 7 along the first direction X, changes the distance between the top sheet 7 and the first side wall, and can clamp the mask 8 of different thicknesses between the top sheet 7 and the first side wall; and can also clamp the mask 8 to prevent it from loosening.

[0036] The adjustment mechanism 6 includes a first adjustment mechanism and a second adjustment mechanism; the first adjustment mechanism is arranged on the second connecting member 2 and connected to the second adjustment mechanism, and is used to drive the second adjustment mechanism to move along the first direction X; the second adjustment mechanism is used to drive the top sheet 7 to move so that the top sheet 7 is close to or away from the first side wall. In this way, the first adjustment mechanism drives the second adjustment mechanism and the top sheet 7 to move along the first direction X, so that the first adjustment mechanism plays a role of coarse adjustment; the second adjustment mechanism drives the top sheet 7 to move along the first direction X, so that the second adjustment mechanism plays a role of fine adjustment.

[0037] Exemplarily, the first adjusting mechanism and the second adjusting mechanism may be an electric push rod, a hydraulic telescopic mechanism, or the like.

[0038] Also exemplarily, the adjustment mechanism 6 also includes a connecting plate 11, the first adjustment mechanism is a first screw 9, and the second adjustment mechanism is a second screw 10; the first screw 9 is threadedly connected to the second connecting member 2, and the first screw 9 is rotatably arranged with the connecting plate 11; the second screw 10 is threadedly connected to the connecting plate 11, and the second screw 10 is rotatably arranged with the top plate 7.

[0039] The axis of the first screw 9 and the axis of the second screw 10 are both perpendicular to the first side wall.

[0040] The first screw 9 is rotatably arranged with the connecting plate 11. For example, the first screw 9 is connected with the connecting plate 11 through the bearing 12, so as to prevent the connecting plate 11 from rotating with the first screw 9. The first screw 9 is sleeved in the inner ring of the bearing 12, and the connecting plate 11 is sleeved in the outer ring of the bearing 12. For example, a threaded hole is provided on the second connecting member 2, and the first screw 9 is threadedly connected in the threaded hole. The threaded hole can be connected with the clamping groove 4, and the axis of the threaded hole is perpendicular to the first side wall. For another example, a nut is provided on the second connecting member 2, and the first screw 9 is threadedly connected in the nut.

[0041] The second screw 10 is rotatably arranged with the top sheet 7. For example, the second screw 10 is connected to the top sheet 7 through a bearing 12, so as to prevent the top sheet 7 from rotating with the second screw 10. The second screw 10 is sleeved in the inner ring of the bearing 12, and the top sheet 7 is sleeved in the outer ring of the bearing 12. For example, a threaded hole is provided on the connecting plate 11, and the second screw 10 can be threadedly connected in the threaded hole. For another example, the connecting plate 11 can be a nut.

[0042] In some examples, the top sheet 7 is slidably disposed in the clamping groove 4. For example, the clamping groove 4 is provided with a slide groove extending along the first direction X, and a portion of the top sheet 7 slides in the slide groove.

[0043] In some examples, the clamping mechanism further includes a back plate 5, which is disposed on the second connecting member 2; the back plate 5 is located on a side of the first side wall away from the top plate 7 and is flush with the first side wall. In this way, the size of the clamping groove 4 along the second direction Y is indirectly increased, thereby preventing the mask 8 from slipping out of the clamping groove 4.

[0044] The first side walls of the clamping grooves 4 of the pair of clamping mechanisms are flush. The distance measuring mechanism is used to measure the distance between the top sheet 7 and the first side wall along the first direction X. In this way, when the distances between the top sheet 7 and the first side wall measured by the two distance measuring mechanisms are equal, it means that the clamped mask 8 is in a state perpendicular to the first direction X (for example, Figure 1 , that is, the mask 8 is not tilted, thereby solving the problem of needing to manually measure the level of the mask 8.

[0045] When in use, if the values ​​measured by the two distance measuring mechanisms are different, the first adjusting mechanism and the second adjusting mechanism of the two clamping mechanisms can be adjusted respectively so that the values ​​measured by the distance measuring mechanisms of a pair of clamping mechanisms are the same.

[0046] The distance measuring mechanism is a distance sensor, which can be an infrared sensor or other sensors, which is common knowledge in the art and will not be described in detail. The distance measuring mechanism can also be a caliper or the like.

[0047] In some examples, the distance measuring mechanism is arranged on the top sheet 7. Of course, the distance measuring mechanism can also be arranged on the second connecting member 2.

[0048] The above description is only an implementation method of the present application, and does not limit the patent protection scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
