Description

Technical Field

[0001] This invention relates to the field of tissue section mounting technology, and more specifically to a loading and unloading device for a slide holder during tissue section mounting. Background Technology

[0002] Tissue slide mounting involves sealing and preserving tissue slides between a glass slide and a coverslip, applying a small amount of mounting adhesive to prevent contact with air, thus preventing oxidation and fading. This facilitates microscopic observation and preservation. Neutral resins are typically used for mounting.

[0003] Currently, the mounting of tissue sections involves manually picking up a slide holder to load the slide, and then manually unloading the slide holder before placing the next slide holder to be mounted. When multiple slide holders need to be mounted, the operator needs to repeat the actions multiple times, resulting in high manual labor intensity. Furthermore, as the operator becomes more fatigued, work efficiency gradually decreases. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a loading and unloading device for slide holders during tissue sectioning and mounting. This device can automatically load and unload multiple slide holders. Combined with automated dispensing and mounting devices, it can automate the entire slide mounting process and replace manual methods.

[0005] The technical solution of the present invention is as follows:

[0006] A slide holder loading and unloading device for mounting tissue sections includes a slide holder loading bin, a screw lifting device, a slide holder support plate, a first micro electric push rod, a slide holder push plate, and a slide holder unloading bin;

[0007] The slide holder loading bin allows slide holders to be sealed to be placed from top to bottom;

[0008] The slide holder plate is movably installed in the slide holder upper hopper and is connected to the screw lifting device on one side of the slide holder upper hopper. It is used to support the slide holder to be sealed in the slide holder upper hopper and drive it to move up and down.

[0009] The slide holder unloading bin is located below the slide holder loading bin and is used to receive the slide holders that have been sealed.

[0010] The slide holder pusher is movably installed in the slide holder unloading bin and is pushed out by the first micro electric push rod to push the sealed slide holder to the unloading buffer position.

[0011] Furthermore, it also includes a second miniature electric push rod and a slide holder baffle. The slide holder baffle is movably disposed on one side of the slide holder's upper hopper and is pushed out by the second miniature electric push rod to separate the upper slide holder with slides to be sealed from the lower slide holder with slides already sealed.

[0012] Furthermore, the slide holder hopper is composed of several sliding plates and slide baffles.

[0013] Furthermore, the lead screw lifting device includes a motor, a lead screw, a synchronous belt, and a synchronous pulley. The motor and the lead screw are connected through the synchronous belt and the synchronous pulley. The slide holder plate is connected to the nut on the lead screw. The motor and the lead screw work together to drive the slide holder plate to move up and down.

[0014] Furthermore, the slide holder unloading hopper includes a support plate and three supports, which are horizontally and evenly arranged on the support plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention can complete the automated loading and unloading of multiple slide holders. Combined with automated dispensing and sealing devices, it can realize the full automation of the slide holder sealing process, replace manual methods, greatly reduce the intensity of manual labor, and ensure work efficiency.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0021] Example

[0022] Please see Figure 1 , Figure 2 This embodiment provides a slide holder loading and unloading device for sealing tissue sections, including a slide holder loading bin, a screw lifting device, a slide holder support plate 8, a first micro electric push rod 11, a slide holder push plate 12, a slide holder unloading bin, a second micro electric push rod 10, and a slide holder baffle plate 9. The slide holder loading bin can hold slide holders 7 to be sealed from top to bottom, and can hold three slide holders 7 at a time. The slide holder loading bin is composed of a first sliding groove plate 3, a second sliding groove plate 4, a third sliding groove plate 6, and a slide baffle plate 5. The first sliding groove plate 3, the second sliding groove plate 4, and the third sliding groove plate 6 form a groove, which together limit the position of the slide holder 7. The slide holder 7 can slide up and down within the groove by gravity. The slide baffle plate 5 is used to limit the position of the slides within the slide holder 7, and the inclined surface on the slide baffle plate 9 can be used to guide protruding slides back. The slide holder plate 8 is movably mounted in the slide holder upper hopper and is connected to a screw lifting device on one side of the slide holder upper hopper. It is used to support the slide holder 7 to be sealed in the slide holder upper hopper and drive it to move up and down. Specifically, the screw lifting device includes a motor 1, a screw 2, a synchronous belt and a synchronous pulley. The motor 1 and the screw 2 are connected through the synchronous belt and the synchronous pulley. The slide holder plate 8 is connected to the nut of the screw 2. The motor 1 and the screw 2 work together to drive the slide holder plate 8 to move up and down. The slide holder unloading bin is located below the slide holder upper loading bin and is used to receive the sealed slide holders 7. It can buffer three sealed slide holders 7. Specifically, the slide holder unloading bin includes a support plate 13 and three supports 14. The three supports 14 are horizontally and evenly arranged on the support plate 13. The three supports 14 support the sealed slide holders 7. The slide holder push plate 12 is movably set in the slide holder unloading bin and is pushed out by the first micro electric push rod 11 to push the sealed slide holders 7 to the unloading buffer position. Automatic slide sealing can be achieved by setting automatic slide removal, glue dispensing, cover slide removal, and cover slide capping devices between the slide holder unloading bin and the slide holder upper loading bin. After sealing, the slides are lowered into the slide holder unloading bin for unloading. The slide holder baffle 9 is movably installed on one side of the slide holder's hopper. It is pushed out by the second micro electric push rod 10 to separate the slide holders with slides to be sealed above from the slide holders with slides already sealed below.

[0023] The specific implementation process is as follows:

[0024] 1. Place the slide holder 7 containing the slides into the slide groove formed by the first slide plate 3, the second slide plate 4 and the third slide plate 6 until the slide holder 7 is supported by the slide holder support plate 8. Then place another slide holder on top of the first slide holder. A maximum of three slide holders 7 can be loaded at one time.

[0025] 2. Under the guidance of the slide baffle 5, the degree of protrusion of the slides in the slide holder remains basically consistent;

[0026] 3. As the slide holder plate 8 moves downwards, the three slide holders reach the working position. The automatic slide removal, glue dispensing, cover slip removal, and cover slip application are then used to automatically seal the slides. After sealing, the slides are returned to the slide holder.

[0027] 4. After the first slide holder has finished sealing, the second miniature electric push rod 10 drives the slide holder baffle 9 to extend forward, separating the two slide holders to be sealed from the first slide holder that has finished sealing.

[0028] 5. The slide holder plate 8 continues to move downward, driving the slide holder that has been sealed to continue downward until it is supported by the three pillars 14 of the slide holder unloading hopper and detached from the slide holder plate 8.

[0029] 6. The slide holder push plate 12 is pushed outward by the first micro electric push rod 11 to complete the sealing of the slide holder. The slide holder 7 slides on the three support pillars 14. After it is in place, the first micro electric push rod 11 retracts.

[0030] 7. The slide holder plate 8 returns to the loading point, supporting the second slide holder. The slide holder blocking plate 9 retracts, and the sealing of the second slide holder continues.

[0031] 8. At this point, there are only two slide holders left in the slide holder hopper, and a new slide holder to be sealed can be added directly;

[0032] 9. When the third slide holder that has completed sealing is pushed out to the unloading position by the slide holder pusher plate 12, a full material alarm will be triggered to prompt personnel to pick up the material.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
