As shown in fig. 1, a slide platform according to an embodiment of the present application includes an X-displacement mechanism, a Y-displacement mechanism, and a Z-displacement mechanism that can reciprocate in a X, Y, Z axis direction of a space rectangular coordinate system, respectively. For convenience of description, a space rectangular coordinate system shown in the drawings is introduced to explain related structures of the embodiments of the present application, wherein a direction shown by an X axis is a right direction, a direction shown by a Y axis is a rear direction, and a direction shown by a Z axis is an upper direction.

Wherein, Y displacement mechanism is the installation basis of X displacement mechanism and Z displacement mechanism. The X displacement mechanism is arranged on the Y displacement mechanism, and the Z displacement mechanism is arranged on the X displacement mechanism. And the X displacement mechanism and the Y displacement mechanism are provided with through holes for the Z displacement mechanism to pass through, so that the Z displacement mechanism can pass through the X displacement mechanism and the Y displacement mechanism, and the space occupation of the whole glass slide carrying platform is reduced.

As shown in fig. 3, the Z-shift mechanism includes a stage 18, a first limit mechanism 20, and a second limit mechanism 21. The stage 18 is mainly used for carrying the slide 27, and a positioning groove for positioning the insertion depth of the slide 27 is formed on the stage 18, i.e. the forward insertion depth of the slide 27 on the stage 18 is mainly determined by the positioning groove.

The first and

second stopper mechanisms

20 and 21 are sequentially disposed on the stage 18 along the insertion direction of the slide 27, the first stopper mechanism 20 is located at the rear side of the second stopper mechanism 21, and the first and

second stopper mechanisms

20 and 21 are used for defining the positions of the slide 27 in the width direction thereof when the slide 27 is inserted, that is, the first and

second stopper mechanisms

20 and 21 are used for defining the left and right positions of the slide 27 when the slide 27 is inserted. Specifically, the first limiting mechanism 20 and the second limiting mechanism 21 each include two guide pressing blocks perpendicular to the insertion direction of the slide 27 and disposed at the left and right sides of the positioning slot at intervals.

As shown in fig. 6, the guide press block includes a connection portion 28 and a projection 29. The connection portion 28 is connected to the stage 18, the protruding portion 29 is connected to a side (i.e., an upper side) of the connection portion 28 away from the stage 18, and the protruding portion 29 protrudes toward the positioning groove. In this way, when the slide 27 is placed on the stage 18, the slide 27 needs to pass through the first limiting mechanism 20 and the second limiting mechanism 21 in sequence from back to front and then is inserted into the positioning groove, the insertion depth of the slide 27 is mainly determined by the positioning groove, the connecting portion 28 of the guide pressing block in the first limiting mechanism 20 and the second limiting mechanism 21 limits the slide 27 not to shake in the left-right direction, and the protruding portion 29 limits the slide 27 not to shake in the up-down direction, so that the slide 27 has a unique insertion movement route, and the slide 27 can be conveniently and rapidly positioned and accurately positioned when the stage 18 is inserted, thereby improving the detection efficiency of the slide.

To facilitate insertion of the slide 27, as shown in fig. 6, the connection portion 28 of the guide block has a chamfer S1 on a side close to the positioning groove, the chamfer S1 being located on a side facing the insertion direction of the slide 27, and the chamfer S1 being gradually tapered along the insertion direction of the slide 27. Corresponding to this, the corresponding position of the projection 29 of the guide block is also provided with a chamfer S2. In this way, during the insertion of the slide 27, the slide 27 does not collide with the guide block due to the guiding action of the chamfer S1 and the chamfer S2, and the insertion process is smoother.

In order for the slide 27 to be inserted into the detent on the stage 18 relatively smoothly, the width of the detent generally needs to be slightly greater than the width of the slide 27, but this may result in the slide 27 being positioned in the detent with insufficient accuracy. Therefore, in order to further improve the accuracy of the position of the slide 27 in the positioning groove, as shown in fig. 3 and 4, the Z-displacement mechanism according to the embodiment of the present application may further include a rotation plate 19 and a rotation return mechanism 23. The rotating plate 19 is rotatably connected to the stage 18 by the rotation resetting mechanism 23 and located at one side of the positioning groove, for example, the rotating plate 19 is located at the right side of the positioning groove, and one side (i.e., the left side) of the rotating plate 19 close to the positioning groove is an arc edge, so that the slide 27 presses the arc edge to push the rotating plate 19 to rotate (counterclockwise in fig. 1) during the insertion of the slide 27 into the positioning groove. The rotational reset mechanism 23 is used for providing a restoring force for the rotational plate 19 to restore to the state before rotation, i.e. the rotational reset mechanism 23 can always provide a leftward pushing force for the slide 27, so that the left side of the slide 27 can always be aligned with the left side edge of the positioning slot, thereby making the position of the slide 27 in the positioning slot unique and accurate. The rotation return mechanism 23 may be a torsion spring mechanism capable of providing a rotational return force after rotation to rotate the rotation plate 19 clockwise. In addition, a micro switch 22 can be arranged on the objective table 18, and a contact extends out of the rotating plate 19, after the rotating plate 19 rotates a certain angle in the process of inserting the slide 27 into the positioning groove, the contact triggers the micro switch 22, and the micro switch 22 can feed back signals to a corresponding control system to indicate that the slide 27 is inserted into the positioning groove, so that other slides 27 are prevented from being inserted.

As shown in fig. 1 and 2, the Y displacement mechanism according to the embodiment of the present application may include a Y base plate 1, a Y slide rail 5, a Y motor 2, and a Y rack 10. Wherein the Y base plate 1 is arranged parallel to the plane where the X axis and the Y axis are located.

The Y slide rail 5 and the Y motor 2 are both fixedly arranged, for example, on a base platform (the base platform is not shown in the drawings). The Y slide rail 5 is parallel to the Y rack 10, the Y bottom plate 1 is slidably connected to the Y slide rail 5, and a Y rack 10 can be correspondingly arranged on the left side and the right side of the Y bottom plate 1 respectively to enhance the stability of the Y bottom plate 1 when sliding on the Y slide rail 5. The Y rack 10 is in transmission connection with the Y motor 2, a gear is arranged on a rotating shaft of the Y motor 2, the gear is meshed with the Y rack 10, and the Y motor 2 can drive the Y bottom plate 1 to slide on the Y slide rail 5 when rotating. And a through hole for the Z displacement mechanism to pass through is formed in the Y bottom plate 1.

In order to detect the movement of the Y-baseplate 1, the Y-displacement mechanism described in the embodiments of the present application may further include a Y-magnetic grating head 3 and a Y-magnetic grating 4 that are used in a matched manner. The Y magnetic grid 4 is fixedly arranged parallel to the Y rack 10, for example fixedly arranged on a base platform (base platform not shown in the figures). The Y magnetic grid head 3 is arranged on the Y bottom plate 1. The Y-shaped magnetic grating head 3 and the Y-shaped magnetic grating 4 form a magnetic grating length sensor together, which is a position measuring device for recording the number of magnetic waves by adopting an electromagnetic method, and the working principle is an electromagnetic induction principle, and when a coil moves at a constant speed near the surface of a periodic magnet, the coil can generate continuously-changing induced electromotive force. The magnitude of the induced electromotive force is related to the degree of motion of the coil, and also to the magnitude and rate of change of magnetism when the magnetic body contacts the coil. Information on the relative position and movement of the coil and the magnet can be obtained based on the change in the induced electromotive force.

At least one X limiting mechanism 6 is arranged on the Y bottom plate 1 of the Y displacement mechanism at the limit positions corresponding to the left and right ends of the X bottom plate 8.
