The feeding device delivers the wiping cloth and covers it, allowing the wiping cloth to be in a relaxed state for degreasing. Simultaneously, the rotation positioning plate rotates downwards. After a limited time, the receiving component tightens the wiping cloth, causing it to rotate upwards until the limit switch is triggered, ending the receiving process. This invention enables fully automated oil removal, ensuring rapid and effective removal of immersion oil from slides without damaging cells, saving manpower and time, and thus enabling faster cleaning of slides after bone marrow smear scanning.

Description

Technical Field

[0001] This invention relates to the field of bone marrow smear scanning equipment, and more particularly to a slide degreasing mechanism for bone marrow smear scanners. Background Technology

[0002] Currently, most bone marrow cell image acquisition methods involve placing slides individually on a stage and moving the stage to focus and acquire images. While slides are primarily used in medical laboratories for observing formed elements in the microscopic world under a microscope, the observation of bone marrow cell morphology requires the aid of immersion oil to see detailed morphology under 100x magnification. For bone marrow smears to be scanned at 100x magnification, immersion oil needs to be applied to the slide first. After imaging, the slide needs to be cleaned of the immersion oil for better preservation. Therefore, treating the immersion oil on the slide is crucial for its preservation.

However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0037] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0038] like Figures 1 to 3As shown, a slide degreasing mechanism for a bone marrow smear scanner includes a base plate 2, a base plate 1 vertically mounted on the base plate 2, and a control device. The base plate 1 has an opening for a robotic arm to grip a slide 100 and quickly pass it to the slide wiping position. The base plate 1 also has:

[0039] The feeding drum 3 is used to hold the oil-removing wiping cloth 200;

[0040] The feeding device, which is electrically connected to the control device, is used to convey the wiping cloth 200 of the feeding roll 3 to the top of the glass slide;

[0041] The receiving sensor component is electrically connected to the control device and is used to remove oil from the glass slides using the wiping cloth 200.

[0042] The take-up drum, electrically connected to the control device, is used to recycle the oil-removing cloth 200 that has undergone the oil removal operation.

[0043] A receiving device is used to transport the degreasing wipes to a receiving roll.

[0044] The control device enables automated control of the feeding device, the receiving sensing component, and the receiving device.

[0045] The receiving sensing component includes a rotation positioning plate 11, a rotation shaft 12, a limit switch mounting plate 13, a limit switch 14, and a sensing rod 10. The limit switch 14 is fixed to the base plate 1 via the limit switch mounting plate 13. The rotation shaft 12 is fixed to the base plate 1. The rotation positioning plate 11 can rotate around the rotation shaft 12. The sensing rod 10 is disposed on the rotation positioning plate 11 and is used to determine whether the oil-removing wiping cloth 200 is tensioned. The limit switch 14 is electrically connected to the control device. The tension state of the wiping cloth 200 in the slide oil removal mechanism of the bone marrow smear scanner is as follows: Figure 2 As shown, the wiping cloth 200 is in a relaxed state as follows: Figure 3 As shown.

[0046] A proximity switch 23 for detecting the state of the wiping cloth 200 on the unloading drum 3 can be provided on the base plate 1. The proximity switch 23 is fixed to the base plate 1 by a proximity switch mounting block 24 and is electrically connected to a control device. Unloading drum 3 has unloading baffles 20 on its inner and outer sides respectively. A second rubber-headed bolt 26 is located at the center of the outer unloading drum 3, which is used to fix the unloading drum baffle 20 to both sides of the unloading drum 3. A take-up drum 9 has a take-up drum baffle 21 and a take-up clamping end cap 22 on its inner and outer sides respectively. A first rubber-headed bolt 25 is located at the center of the outer take-up clamping end cap 22, which is used to fix the take-up drum baffle 21 and the take-up clamping end cap 22 to both sides of the take-up drum 9. Both the unloading drum baffle 20 and the take-up drum baffle 21 are used to prevent the wiping cloth 200 from slipping off the drum.

[0047] The wiping cloth 200 passes sequentially through the feeding roll 3, the feeding device, above the glass slide 100, the receiving device, and the receiving roll 9. During the degreasing operation, after the sensing rod 10 determines that the wiping cloth 200 is tensioned, the feeding device delivers the wiping cloth 200 above the glass slide 100, allowing the wiping cloth 200 to relax and perform the degreasing operation on the glass slide 100. The rotating plate 11 then rotates downwards. After a limited time, the receiving device tightens the wiping cloth 200, causing the wiping cloth 200 to drive the rotating plate 11 to rotate upwards until it triggers the limit switch 14. Through the above automated degreasing operation, the immersion oil on the glass slide can be removed quickly, simply, and effectively, reducing labor and saving time for laboratory workers.

[0048] Specifically, the feeding device may include a feeding motor assembly 4, a timing belt 8, a feeding roller assembly 6, and a left-side baffle auxiliary plate 17 fixed on the base plate 1.

[0049] Among them, such as Figure 5 As shown, the feeding motor assembly includes a feeding motor 41, a feeding motor mounting plate 42, a feeding coupling 44, a discharge pulley shaft 45, and a first pulley 46. The feeding motor 41 is mounted on the base plate 1 via the feeding motor mounting plate 42. The output end of the feeding motor 41 is connected to the discharge pulley shaft 45 via the feeding coupling 44. The first pulley 46 is located on the discharge pulley shaft 45.

[0050] like Figure 6 As shown, the feeding roller assembly 6 includes a guide seat 61 fixed to the base plate 1 and used to guide the wiping cloth 200 in the direction and a feeding roller 62 provided on the guide seat 61. One end of the feeding roller 62 is provided with a second pulley 63, and the other end of the feeding roller 62 is connected to a sensing plate 64. The guide seat 61 is provided with a photoelectric switch 65 corresponding to the sensing plate 64.

[0051] The two ends of the synchronous belt 8 are respectively located on the first pulley 46 and the second pulley 63. The left baffle 18 is located on the lower left of the feeding roller assembly and the guide limit of the wiping cloth 200 is located on the right side of the left baffle 18. The feeding motor 41 and the photoelectric switch 65 are electrically connected to the control device.

[0052] Here, through the coordinated operation of photoelectric switch 65 and sensor plate 64, a new wiping cloth 200 is sent to the left baffle 18 via guide seat 61; sensor plate 64 and photoelectric switch 65 can be mounted on feed roller 62 and guide seat 61 respectively via feed roller mounting plate 66; each time sensor plate 64 rotates half a turn, the length of wiping cloth 200 used for each degreasing operation is consistent.

[0053] Specifically, the feeding device may also include an auxiliary pressure roller assembly 7, used to assist the feeding roller assembly 6 in guiding the wiping cloth 200 into a set track. For example... Figure 7As shown, the auxiliary pressure roller assembly 7 includes a rotary mounting base 71 fixed on the base plate 1, a rotary pressure roller seat 81 rotatably connected to the rotary mounting base 71, and a pressure roller 72 disposed on the rotary pressure roller seat 81. The pressure roller 72 is arranged opposite to the feeding roller 62 so that the wiping cloth 200 is limited to be located between the pressure roller 72 and the feeding roller 62. The rotary mounting base 71 and the rotary pressure roller seat 81 can be sleeved together on the pressure roller shaft 80. A torsion spring 73 can be sleeved on the end face of the pressure roller shaft 80. A retaining spring plate 74 is provided on the rotary pressure roller seat 81 to prevent the torsion spring 73 from dislodging from the pressure roller shaft 80. A pressing positioning rod 75 is inserted inside the rotary pressure roller seat 81, and a pressing head 77 is provided on the protruding part. A compression spring 78 is sleeved on the pressing positioning rod 75 near the pressing head 77. The two ends of the pressure roller 72 are mounted on the rotary pressure roller seat 81 through pressure roller support shafts 79.

[0054] The feeding device may also include a left side baffle 18, which is disposed on the side of the left side baffle auxiliary plate 17. The two are perpendicular to each other and limit the wiping cloth 200.

[0055] The receiving device may include a receiving motor assembly 5 and a right side baffle 15 and a right guide shaft 16 on a fixed base plate.

[0056] The take-up motor assembly 5 includes a take-up motor 51, a take-up motor mounting plate 52, a take-up coupling 53, and a take-up rotating shaft 54. The take-up motor 51 is mounted on the base plate 1 through the take-up motor mounting plate 52. The output end of the take-up motor 51 is connected to the take-up rotating shaft 54 ​​through the take-up coupling 53. The take-up rotating shaft 54 ​​is connected to the take-up drum 9.

[0057] The right baffle 15 is located to the right of the receiving sensing assembly, and the guide limit for the wiping cloth 200 is located above the right baffle 15. The right guide shaft 16 is located to the right of the right baffle 15, and the guide limit for the wiping cloth 200 is located below the right guide shaft 16. The receiving motor 51 is electrically connected to the control device. Here, the right baffle 15 can be inclined, for example, in a left-lower-right-upper direction. The outer side of the right baffle 15 can be provided with a protrusion, thereby forming a concave elongated track on the surface of the right baffle 15 to prevent the wiping cloth 200 from sliding out of the right baffle 15.

[0058] When a new wiping cloth 200 is needed for the degreasing operation, the feeding device will feed the wiping cloth 200 from the unloading drum 3 through the guide seat 61 of the feeding roller assembly 6, the left baffle 18 and the left baffle auxiliary plate 17, and deliver it above the glass slide 100, so that the wiping cloth 200 is in a relaxed state to perform the degreasing operation on the glass slide 100; after the degreasing operation is completed, the receiving device will tighten the wiping cloth 200, so that the wiping cloth 200 passes through the right baffle 15 and the right guide shaft 16 in sequence and is stored on the receiving drum 9.

[0059] The main support structure of this invention consists of a vertical base plate 1 and a horizontal base plate 2. To enhance the strength of the base plate 1, one or more reinforcing ribs 19 may be provided on the base plate 1. The sides of the reinforcing ribs 19 are connected to the base plate 1, and the bottom edges are connected to the base plate 2. The number and distribution of the reinforcing ribs 19 can be set and adjusted according to actual needs. The area enclosed by the base plate 1, the base plate 2, and the reinforcing ribs 19 can serve as a storage area for placing a slide collecting device, an oil wiping cloth 200 storage device, a spare component storage box, an oil can, etc.

[0060] To maintain the balance on both sides of substrate 1, such as Figure 4 As shown, the feeding drum 3, the take-up drum 9, the timing belt 8, the feeding roller assembly 6, and the take-up sensing assembly are all located on the same side of the substrate 1, such as the front side of the substrate 1; the feeding motor 41 and the take-up motor 51 are located on the other side of the substrate 1, such as the back side of the substrate 1. For example, in the feeding motor assembly 4, the feeding motor 41 is mounted on the back side of the substrate 1 via the feeding motor mounting plate 42, while the first pulley 46 connected to the timing belt 8 can be mounted on the front side of the substrate 1 via the movable plate 43; in the take-up motor assembly 6, the take-up motor 51 is mounted on the back side of the substrate 1 via the take-up motor mounting plate 52, while the take-up rotating shaft 54, which is connected to the take-up motor 51 via the take-up coupling 53, is mounted on the front side of the substrate 1, and the take-up rotating shaft 54 ​​is connected to the take-up drum 9 on the front side of the substrate 1.
