Description

Technical Field

[0001] The invention belongs to the field of glass slide racks in machine vision imaging or electron microscope scanning technology, and particularly relates to a side-pushing glass slide rack with three bottom point supports. Background Art

[0002] In the field of machine vision imaging or electron microscope scanning, in order to restore the natural state of the test sample and ensure the accuracy of the test results, in addition to the increasingly high requirements for the movement stability of the slide rack within the scanning area, there are also high requirements for the horizontality of the slide when it is placed on the slide rack.

[0003] In the existing slide rack structure, when fixing the slide, the slide is placed directly on the slide rack, and the slide rack directly uses a spring push block structure to fix the slide. In addition, most slide racks use a top-push design to push the slide tightly from the top. This structure has the following disadvantages:

[0004] 1. The slide is placed directly on the slide rack, but the surface of the slide and the slide rack is not completely flat. When the contact point between the two is uncertain, the slide cannot be as level as possible on the slide rack;

[0005] 2. The spring push block structure is used. When clamping and releasing, there is a gap between the push block and the track, and the push block will rise, causing the glass slide to warp;

[0006] 3. Under the same clamping force, the top-push design generates a much greater force arm on the glass slide than the side-push design. The larger the force arm, the greater the deformation of the glass slide.

[0007] As can be seen from the above shortcomings, the existing slide racks cannot meet the requirements of machine vision imaging or electron microscope scanning for the horizontality of the slides, which may cause errors and thus affect the detection results. Summary of the Invention

[0008] In response to the defects of the existing technology, the present invention provides a bottom three-point supported side-pushing glass slide rack to keep the glass slide as level as possible, avoid the glass slide from warping when clamped or loosened, and reduce the deformation of the glass slide when clamped.

[0009] In order to solve the above technical problems and achieve the above technical effects, the present invention is implemented through the following technical solutions:

[0010] The top of the support frame is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate. The top screw through hole is located at the angle between the front end limit plate of the glass slide and the inner support block of the glass slide, and the top screw through hole on the right is located at the angle between the front end limit plate of the glass slide and the elastic leaf spring composite pushing block structure of the outer side of the glass slide. A top screw adjustment component for adjusting the level of the glass slide is respectively provided on the lower surface of the glass slide rack main board corresponding to the positions of the left and right two top screw through holes, and the top screws of the two top screw adjustment components respectively pass upward from the two corresponding top screw through holes; the glass slide is placed in the recess by the three-point support of the rear end support protrusion at the bottom of the glass slide and the two top screws, and the glass slide is fixed in the recess by the clamping cooperation of the front end limit plate of the glass slide, the rear end limit strip of the glass slide, the inner support block of the glass slide, the outer limit pin of the glass slide and the elastic leaf spring composite pushing block structure of the outer side of the glass slide.

[0011] Furthermore, the spring composite push block structure on the outer side of the glass slide consists of a spring fixing frame, a spring, a spring and a spring spring head. The spring fixing frame is fixed to the front end of the outer edge of the recess, the front end of the spring is fixed to the front end of the inner side of the spring fixing frame, the spring spring head is fixed to the inner side of the rear end of the spring, one end of the spring is fixedly connected to the outer side of the rear end of the spring, and the other end of the spring is fixedly connected to the rear end of the inner side of the spring fixing frame.

[0012] Furthermore, a spring retainer mounting groove for fixing the spring retainer is provided on the upper surface of the slide rack mainboard.

[0013] Furthermore, the leaf spring fixing frame is composed of a leaf spring fixing block located at the front, a spring fixing block located at the rear, and a side inclined block connected between the leaf spring fixing block and the spring fixing block. The width of the leaf spring fixing block is greater than the width of the spring fixing block. A leaf spring mounting hole is provided on the inner side surface of the leaf spring fixing block. A spring mounting hole is provided on the inner side surface of the side inclined block. An avoidance inclined surface is provided on the inner side surface of the side inclined block to facilitate the outer shape deformation of the leaf spring.

[0014] Furthermore, the spring sheet elastic head includes an integrally formed side push contact head, a side push contact head mounting plate, a paddle and a paddle connecting plate, the outer side surface of the side push contact head mounting plate is fixedly connected to the inner side surface of the spring sheet, the side push contact head is fixed to the inner side surface of the side push contact head mounting plate, the inner end of the paddle connecting plate is connected to the top end of the side push contact head mounting plate, and the paddle is arranged at the outer end of the upper surface of the paddle connecting plate.

[0015] Furthermore, the side-pushing contact head is in an inverted triangle shape. At the same time, an inverted triangle contact strip is provided on the side of the contact surface between the inner support block of the glass slide and the glass slide, and two inverted triangle contact blocks are provided side by side on the side of the contact surface between the rear end limit strip of the glass slide and the glass slide, thereby providing a certain downward pressure when the glass slide is clamped, and further preventing the glass slide from warping.

[0016] Furthermore, a slide loading pin is provided on the upper surface of one corner of the slide rack main board.

[0017] Furthermore, a detachable slide rack handle is provided on one side end surface of the slide rack main board via a pin shaft.

[0018] Furthermore, the surface of the slide rack handle is provided with anti-slip grooves.

[0019] Furthermore, the front end limit plate of the glass slide, the rear end limit bar of the glass slide, the inner side support block of the glass slide and the spring fixing frame are all fixed to the main board of the glass slide rack by corresponding screws.

[0020] Furthermore, the main board of the glass slide rack adopts a symmetrical double-concave design, that is, the front end limit plate of the glass slide, the rear end limit bar of the glass slide, the inner support block of the glass slide, the outer spring composite push block structure of the glass slide and the outer limit pin of the glass slide located in the two concave pockets are all distributed in a mirror image, and the hollow structures in the middle of the two concave pockets are connected to each other.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention uses the principle that three points can determine a plane and adopts a three-point support method to carry the glass slide. Compared with the traditional surface contact support method between the glass slide rack and the bottom surface of the glass slide, the three-point support can keep the glass slide as level as possible on the glass slide rack and is no longer affected by the flatness of the surface of the glass slide rack cavity.

[0023] 2. In the three-point support structure of the present invention, the rear end adopts a single-point fixed support, and the left and right sides of the front end adopt a top screw adjustment structure support. Therefore, when the glass slide is not in a horizontal state, the position height of the left and right sides of the front end of the glass slide can be adjusted in time through the two top screws, thereby quickly and conveniently adjusting the level of the glass slide.

[0024] 3. The present invention adopts a side-push wave plate clamping design. Therefore, under the condition of the same clamping force, the force arm generated by the side-push type is much smaller than that of the top-push type, and the deformation caused to the glass slide is also smaller, thereby effectively reducing the deformation of the glass slide during clamping.

[0025] 4. The side push block of the present invention adopts a composite elastic structure of springs and springs, which eliminates the gap between the side push block and its slide. In addition, the side push block and some support blocks and limit strips have inverted triangular contact pressure points. Therefore, the combination of the two can make the glass slide tightly attached to the three support points, thereby effectively preventing the glass slide from warping in the recess after being clamped.

[0026] It can be seen from the above advantages that the present invention can keep the glass slide as level as possible during scanning, prevent the glass slide from tilting and reduce the deformation of the glass slide when clamping, and meet the requirements of machine vision imaging or electron microscope scanning for the horizontality of the glass slide, thereby avoiding errors and ensuring the detection results.

[0044] Furthermore, a slide loading pin 14 is provided on the upper surface of one corner of the slide rack main board 1 .

[0045] Furthermore, a detachable slide rack handle 12 is provided on one side end surface of the slide rack main board 1 via a pin.

[0046] Furthermore, an anti-slip groove 13 is provided on the surface of the slide rack handle 12 .

[0047] Furthermore, the front end limit plate 4 of the glass slide, the rear end limit bar 5 of the glass slide, the inner side support block 6 of the glass slide and the spring fixing frame 71 are all fixed to the glass slide rack main board 1 by corresponding screws.

[0048] Furthermore, the glass slide rack main board 1 adopts a symmetrical double-concave design, that is, the glass slide front end limit plate 4, the glass slide rear end limit bar 5, the glass slide inner support block 6, the glass slide outer spring composite push block structure 7 and the glass slide outer limit pin 8 located in the two concave pockets 3 are all distributed in a mirror image, and the hollow structures in the middle of the two concave pockets 3 are connected to each other.

[0049] The working principle of the present invention is as follows:

[0050] When a glass slide 2 needs to be placed into the recess 3 on the main slide holder 1, the spring head 74 is first pushed outward to open the recess 3. The spring head 74 then bends the spring 72 toward the avoidance slope 716 of the spring spring holder 71. Simultaneously, the spring 72 exerts a force on the spring 73, squeezing the spring. The glass slide 2 is then placed into the recess 3. The bottom surface of the glass slide 2 is supported by three points: a support protrusion 9 at the rear end of the glass slide and two screws. Because the bottom surface of the glass slide 2 does not contact the entire recess 3, the principle of three points defining a plane is used to keep the glass slide 2 as horizontal as possible within the recess 3. If the glass slide 2 is not level, the height of the front end of the glass slide 2 can be adjusted using two screws (not shown) on both sides of the front end of the recess 3, allowing the glass slide 2 to be quickly adjusted to its level within the recess 3. The spring-loaded spring head 74 is then released, and under the combined action of the spring 72 and the spring 73, the spring-loaded spring head 74 returns inward, pushing the glass slide 2 from the outside, thereby clamping the glass slide 2 in the limiting structure surrounded by the front-end limiting plate 4, the inner-side support block 6, the rear-end limiting bar 5, the outer-side limiting pin 8, and the spring-loaded spring head 74. Due to the side-pushing clamping design, the side-pushing clamping generates a much smaller force arm than the top-pushing clamping when the clamping force is the same, resulting in less deformation of the glass slide. At the same time, the spring sheet elastic head 74 adopts a composite elastic structure of the spring sheet 72 and the spring 73, which eliminates the gap between the spring sheet elastic head 74 and the spring sheet spring fixing frame 71. In addition, the side push contact head 741, the inner side support block 6 of the glass slide, and the rear end limit strip 5 of the glass slide all have inverted triangular contact pressure points. The combination of the two can make the glass slide tightly attached to the three support points, thereby preventing the glass slide 2 from warping in the recess 3 after being clamped, thereby avoiding measurement errors.

[0051] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
