Abstract
Description
Technical Field
[0001] This utility model relates to the field of HE dyeing machine technology, specifically to a material conveying mechanism for a drop HE dyeing machine. Background Technology
[0002] Staining is of great significance in the diagnosis of pathological tissue morphology, scientific experimental research, and teaching. Without staining tissue sections, the internal structure of the tissue cannot be seen, and the cell nuclei cannot be identified. Therefore, researchers cannot provide a basis for judgment to determine whether the tissue is abnormal.
[0003] HE staining uses hematoxylin and eosin to stain the nucleus and cytoplasm, respectively, to distinguish the morphology of normal cells. In practical applications, it can identify abnormal pathological changes such as tissue cell necrosis, edema, degeneration, and inflammatory cell infiltration.
[0004] Current technology for staining tissue sections mostly relies on manual operation, resulting in low processing efficiency. Therefore, it is necessary to design a device capable of automatically staining tissue sections, which in turn requires a mechanism to transfer the tissue sections between processing stations to achieve automated operation. Utility Model Content

The drop-dye HE staining machine includes a machine base with multiple processing positions. The hopper conveying mechanism includes a hopper flow channel connected to all processing positions. The hopper flow channel is used to convey a hopper containing tissue sections. The machine base is equipped with multiple hopper pushing mechanisms, which push the hopper to slide on the hopper flow channel. A blocking mechanism and a positioning mechanism are respectively provided on the hopper flow channel at positions corresponding to each processing position. The blocking mechanism is used to prevent the hopper from sliding within the hopper flow channel, and the positioning mechanism is used to limit the hopper to a position within the hopper flow channel corresponding to the processing position.

[0019] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0021] like Figure 1-5As shown, a material conveying mechanism for a drop staining HE staining machine is used to install on the drop staining HE staining machine. The drop staining HE staining machine includes a machine base 100 with multiple processing positions, enabling the drop staining HE staining machine to stain tissue sections in multiple material bins simultaneously, thereby improving processing efficiency.
[0022] The material handling mechanism includes a material handling channel 200. A material loading mechanism is provided on the machine base 100. This mechanism transports a hopper 300 containing tissue slices into the material handling channel 200. The material handling channel 200 is used to transport the hopper 300 containing tissue slices. The material handling channel 200 includes transverse and longitudinal channels, completely covering the machine base 100. The material handling channel 200 can be made of rigid metal plate or high-strength engineering plastic. The entire material handling channel 200 connects various processing stations. A material handling pushing mechanism 1 is provided on the machine base 100. This mechanism pushes the hopper to slide along the material handling channel 200, thereby moving the hopper from one processing station to the next.
[0023] The material hopper flow channel 200 is provided with a blocking mechanism 2 and a positioning mechanism 3 at the corresponding positions of each processing station. The blocking mechanism 2 is used to prevent the material hopper from sliding in the material hopper flow channel 200, and the positioning mechanism 3 is used to limit the material hopper in the material hopper flow channel 200 at the position corresponding to the processing station.
[0024] During actual processing, the feeding mechanism of the HE dyeing machine will transport the hopper to the first processing position within the hopper flow channel 200, and then push the hopper to the second processing position through the corresponding hopper pushing mechanism 1; at the same time, the feeding mechanism of the HE dyeing machine will transport the second hopper to the first processing position within the hopper flow channel 200; and so on, until all processing positions are pushed to the hopper.
[0025] During the aforementioned material pushing process, the blocking mechanism 2 corresponding to the foremost processing position will activate first, blocking the hopper at the foremost processing position. After the hopper arrives in position, the positioning mechanism 3 corresponding to the foremost processing position will activate and limit the hopper to the hopper flow channel 200 corresponding to that processing position. After the hopper at the foremost processing position is pushed into position, the blocking mechanism 2 corresponding to the next processing position will activate, and after the hopper arrives in position, the positioning mechanism 3 at that processing position will activate and limit and fix the hopper to the hopper flow channel 200 corresponding to that processing position. This process continues until all positioning mechanisms 3 have limited and fixed their respective hoppers to their corresponding processing positions, thus completing the material transport process within the hopper flow channel 200.
[0026] To limit the sliding process of the hopper, two hopper limiting plates 4 are bolted parallel to each other on both sides of the upper end face of the hopper flow channel 200. The distance between these two hopper limiting plates 4 is slightly larger than the width of the hopper, thus guiding the movement of the hopper and preventing it from tipping over.
[0027] The hopper pushing mechanism 1 is mounted on the machine base 100, located on one side or below the hopper flow channel 200. In this embodiment, the hopper pushing mechanism 1 includes a pushing fixing frame 11, which is fixed to the machine base 100 by bolts. A hopper pushing motor 12, a hopper pushing driven wheel 13, and a pushing guide rail 14 are mounted on the pushing fixing frame 11. A hopper pushing driving wheel 15 is mounted on the output shaft of the hopper pushing motor 12. A hopper pushing transmission belt 16 is sleeved on the hopper pushing driving wheel 15 and the hopper pushing driven wheel 13. A hopper pushing slider 17 is fixedly mounted on the hopper pushing transmission belt 16, and the hopper pushing slider 17 is slidably engaged with the pushing guide rail 14. A hopper pushing block 18 is fixedly mounted on the hopper pushing slider 17, and the hopper pushing block 18 can extend out of the upper surface of the hopper flow channel 200 and abut against the side or end of the hopper 300. By controlling the hopper drive motor 12 to work, the hopper drive transmission belt 16 can drive the hopper drive slider 17 and the hopper push block 18 to move along the drive guide rail 14, thereby pushing the hopper in the hopper flow channel 200 and realizing the function of pushing the hopper from the previous station to the next station.
[0028] By sliding the hopper pusher 17 and the pusher rail 14 together, the movement direction of the hopper pusher 18 can be limited and guided, ensuring that it can push the hopper to slide within the hopper flow channel 200.
[0029] A blocking mechanism 2 is installed below the material flow channel 200 corresponding to each processing station. The blocking mechanism 2 includes a blocking lifting module, which in this embodiment is a vertically installed blocking electric push rod 21. The blocking electric push rod 21 is fixed on the pushing and fixing frame 11. The output end of the blocking electric push rod 21 passes upward through a preset through hole on the flow channel and is connected to a wedge-shaped or square blocking block 22. After the material hoppers at the previous processing stations have been pushed to the material hoppers, the control system of the HE dyeing machine will automatically control the blocking electric push rod 21 of the next processing station to move, pushing the blocking block 22 to rise and protrude above the upper surface of the material flow channel 200, thus blocking the forward path of the next material hopper and stopping it on the material flow channel 200 corresponding to that processing station. When it is necessary to release the material hopper, the electric push rod retracts, driving the blocking block 22 to descend below the plane of the material flow channel 200, and the material hopper can continue to move forward.
[0030] The positioning mechanism 3 is also located below the material flow channel 200 corresponding to each processing position, usually on one side of the blocking mechanism 2. The positioning mechanism 3 includes a positioning lifting module. In this embodiment, the positioning lifting module uses a vertically installed positioning electric push rod 31. The positioning electric push rod 31 is fixed on the push fixing frame 11, the output end of the positioning electric push rod 31 faces upward, and a mounting block 32 is provided on the output end of the positioning electric push rod 31. Two positioning pins 33 are vertically fixed on the mounting block 32; in other embodiments, the number of positioning pins 33 can also be any other number. Correspondingly, positioning holes 301 matching the shape of the positioning pins 33 are machined at the bottom of the material hopper 300. When the material hopper is stopped by the blocking mechanism 2, the control system commands the positioning electric push rod 31 to move, pushing the mounting block 32 and positioning pins 33 upward, so that the two positioning pins 33 are precisely inserted into the positioning holes 301 at the bottom of the material hopper, thereby constraining the material hopper in the horizontal and vertical directions, achieving precise positioning and locking, and ensuring that other mechanisms of the HE staining machine can operate on the tissue sections in the material hopper. After processing is completed, the positioning electric push rod 31 retracts, driving the positioning pin 33 to descend and separate from the hopper, thus releasing the lock.
[0031] In other embodiments, both the blocking lifting module and the positioning lifting module can be other linear drive devices such as cylinders and motor screw structures.
[0032] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
