Apparatus for holding a substrate within a secondary device
This disclosure is directed to an apparatus for securely holding a substrate, such as a microscope slide. A holder includes a frame including at least three walls, such as a base, a first arm, and a second arm. Each wall includes a platform or a portion of a platform to support the substrate. The first arm includes at least one securing block and a second arm opposite the first arm includes a secure bar with a securing block. The securing blocks include a ramp to guide the substrate off of the platforms and a stopper to set a maximum lift distance and to constrain the substrate.
1. A device comprising:
a base;
a first arm comprising at least one securing block; and
a second arm comprising a secure bar comprising a securing block, and
wherein the first and second arms extend in the same direction from the base,
wherein each securing block comprises a ramp and a stopper,
wherein the ramp is configured to directly contact a substrate and is shaped to translate the substrate at least vertically as the substrate moves against a surface of the ramp until the substrate directly contacts the stopper, and
wherein the stopper is configured to set the maximum translation distance for the substrate and is further configured to constrain the substrate against the stopper and the ramp.
2. The device of claim 1 , wherein the first arm comprises two securing blocks.
3. The device of claim 2 , wherein the securing blocks on the first arm and the securing block on the secure bar provide three points of contact for the substrate when the secure bar is in a closed position.
4. The device of claim 1 , further comprising a platform extending at least partially from the first arm towards the second arm.
5. The device of claim 1 , wherein the base, the first arm, and the second arm form a U-shape.
6. The device of claim 1 , wherein the base, the first arm, and the second arm form a J-shape.
7. The device of claim 1 , further comprising a spring extending from the secure bar to the second arm to pre-load the secure bar.
8. The device of claim 1 , further comprising at least one cutout on an inner corner at the proximal ends of each of the first and second arms where the first and second arms are connected to the base, the at least one cutout to accept a portion of the substrate.
9. The device of claim 1 , further comprising at least one cutout at the distal end of each of the first and second arms.
10. The device of claim 1 , wherein each of the securing blocks comprises at least one height adjuster to adjust the height of each securing block relative to the arm or secure bar to which the securing block is attached and at least one fastener for fastening the securing blocks to the second arm or the secure bar.
11. The device of claim 1 , wherein the secure bar is attached to the second arm by a bearing and a fastener.
12. The device of claim 11 , the secure bar further comprising:
an open position to insert the substrate into or remove the substrate from the holder; and
a closed position to constrain the substrate against the securing blocks.
13. The device of claim 1 , wherein the ramp is shaped to also translate the substrate horizontally.
14. A method comprising:
inserting a substrate into a holder, the holder comprising:
a base;
a first arm comprising at least one securing block; and
a second arm comprising a secure bar comprising a securing block, and
wherein the first and second arms extend in the same direction from the base,
wherein each securing block comprises a ramp and a stopper,
wherein the ramp is configured to directly contact a substrate and is shaped to translate the substrate at least vertically as the substrate moves against a surface of the ramp, and
wherein the stopper is configured to directly contact the substrate and to set the maximum translation distance for the substrate and is further configured to constrain the substrate against the stopper and the ramp; and moving the secure bar from an open position to a closed position, thereby moving the ramp into direct contact with the substrate, and
moving the substrate against the surface of the ramp and translating the substrate at least vertically until the substrate directly contacts the stopper, thereby constraining the substrate against the stopper and the ramp.
15. The method of claim 14 , wherein the base, the first arm, and the second arm form a U-shape or a J-shape.
16. The method of claim 14 , wherein the first arm comprises two securing blocks.
17. The method of claim 16 , wherein the securing blocks on the first arm and the securing block on the secure bar provide three points of contact for the substrate when the secure bar is in the closed position.
18. The method of claim 14 , wherein each of the securing blocks comprises at least one height adjuster to adjust the height of each securing block relative to the arm to which the securing block is attached and at least one fastener for fastening the securing blocks to the second arm or the secure bar.
19. The method of claim 14 , wherein the open position permits the substrate to be inserted into or removed from the holder.
20. The method of claim 14 , wherein moving the substrate against the surface of the ramp also causes the substrate to translate horizontally.
