[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 1-6As shown, an automated pathological staining machine includes a housing 1, an observation sliding door 2, a drive motor 3, a drive cylinder 4, a rotating mechanism 5, and a staining assembly 6. It effectively automates the staining of pathological samples, improving work efficiency and ensuring staining quality. The housing 1 is designed as a cylindrical structure, featuring strong stability and high space utilization, accommodating multiple internal components and providing good protection. An observation sliding door 2, made of transparent material, is installed on the side of the housing 1, allowing operators to observe the staining process and the operating status of the internal components in real time, avoiding the risk of contamination from frequent opening of the housing 1. The drive motor 3 is fixedly installed at the top of the housing 1, serving as the key power source for driving the movement of the internal staining assembly 6. A drive cylinder 4 is located next to the drive motor 3, providing auxiliary driving force to ensure the stability and operational accuracy of the staining assembly 6. Inside the housing 1, a precisely designed rotating mechanism 5 is installed, which, through linkage with the drive motor 3, enables flexible rotation and precise positioning of the staining assembly 6. The staining assembly 6, mounted on top of the rotating mechanism 5, is the core component responsible for carrying the sample and performing the staining operation. Its position and structure can meet the staining requirements of different samples. The overall design is compact and reasonable, which not only realizes the full automation of the operation but also improves the reliability and ease of maintenance of the equipment, making it suitable for efficient staining of various pathological samples.

[0040] like Figure 2 As shown, the rotating mechanism 5 has a compact structure, mainly composed of a rotating shaft 51, a storage block 52, and a movable cover 53, fully embodying the combination of functionality and practicality. The rotating shaft 51, as the core component, is installed below the drive motor 3. Through direct linkage with the drive motor 3, it achieves efficient operation and precise control of the entire rotating mechanism 5. The storage block 52 is installed in the middle of the rotating shaft 51, serving a dual function of connection and load-bearing. Its internal design includes a storage cavity 521 for storing the dyeing agent or other reagents required during the dyeing process, providing a sufficient and stable supply of dyeing agent. The storage cavity 521 not only optimizes the storage conditions of the dyeing agent but also facilitates subsequent dyeing agent delivery.

[0041] A movable cover 53 is provided above the storage block 52. The movable cover 53 provides good sealing protection for the storage chamber 521, preventing the volatilization or contamination of the dye, and also facilitates the operator to replenish or replace the reagent when necessary. The overall design is compact and reasonable, and the operation is efficient and reliable. The movable cover 53 is controlled by the drive cylinder 4 and can automatically move upward when the observation sliding door 2 is opened to facilitate the addition of dye.

[0042] like Figure 2-3As shown, the rotating mechanism 5 includes a conveying pipe 54, a connecting rod 55, and a heating base 56. The conveying pipe 54 is located at the bottom of the storage block 52 and is used to accurately deliver the dyeing agent in the storage chamber 521 to the top of the target dyeing assembly 6, ensuring efficient and leak-free dyeing agent transfer. Its position and connection design are reasonable, adaptable to various dyeing needs, and easy to clean and maintain. The connecting rod 55 is installed on the lower part of the rotating shaft 51. The connecting rod 55 is used to install the dyeing assembly 6 and plays a role in stable support and efficient transmission, ensuring that the entire rotating mechanism 5 has high stability and precision during operation.

[0043] The heating base 56 is installed on the bottom surface inside the housing 1 to provide a suitable temperature environment, thereby optimizing the performance of the dye and improving the dyeing effect. Through the uniform distribution of heat, the heating base 56 can also prevent the dye from solidifying or degrading at low temperatures, further improving the applicability and operational stability of the system.

[0044] like Figure 4 As shown, the feed pipe 54 consists of a feed channel 541, a feed head 542, and a control valve 543. These components work closely together to ensure stable and efficient dye delivery. The feed channel 541 is located inside the feed pipe 54, serving as the main channel for dye flow. Its smooth design eliminates dead angles, effectively reducing dye residue and the risk of clogging. The feed head 542 is installed at the lower end of the feed pipe 54 and is designed as a vertical structure to ensure precise placement of the dye at the target location, preventing deviation or splashing. The control valve 543 is installed inside the feed head 542. By precisely controlling the dye flow rate and its opening / closing status, it achieves quantitative dye output, ensuring consistency and efficiency in the dyeing operation.

[0045] The feed pipe 54 is inclined, which helps the dye flow naturally under gravity, further reducing the conveying resistance. At the same time, it optimizes the conveying path of the dye from the storage chamber 521 to the dyeing component 6, improving the smoothness and efficiency of the dyeing process.

[0046] like Figure 4-5 As shown, the dyeing assembly 6 has a precise structure, including a dyeing box 61, a mounting hole 611, and a sealing assembly 62. It is designed to meet the high precision and high reliability requirements of automated dyeing operations.

[0047] The staining box 61 is installed at the outer end of the connecting rod 55, serving as the main container for sample staining. Its position is rationally designed, facilitating both connection with the feed tube 54 and sample placement and removal. The staining box 61 is made of corrosion-resistant material, ensuring its long-term stable support of various staining agents without corrosion. The mounting hole 611 is located on the top of the staining box 61, providing a dedicated channel for staining agent input. Its size and shape are optimized to effectively prevent staining agent spillage and splashing.

[0048] The sealing component 62 is installed above the dyeing box 61, playing a crucial role in sealing and protecting the dye. It prevents the dye from evaporating during the dyeing process and avoids the intrusion of external contaminants, thus ensuring the purity of the dye and the safety and stability of the dyeing environment. The overall design is simple and efficient, suitable for various dyeing scenarios.

[0049] like Figure 6 As shown, the sealing assembly 62 has an ingenious structural design and mainly consists of a sealing cover 621, an inner baffle 622, an outer baffle 623, a collection surface 624, a feeding hole 625, and a mounting pin 626. The various parts cooperate with each other to ensure the efficiency and stability of the dyeing process.

[0050] The sealing cap 621, installed on top of the dyeing box 61, is a crucial protective device for the sealing assembly 62. It effectively prevents the dye from evaporating or becoming contaminated by external factors, while ensuring the airtightness of the environment inside the dyeing box 61. The inner baffle 622 is directly connected to the sealing cap 621, guiding the flow of the dye and acting as a diverter and prevents splashing. The outer baffle 623 is installed on one side of the inner baffle 622, forming a closed working area together with the inner baffle 622, further enhancing the safety and precision of the dyeing operation.

[0051] The collecting surface 624, located between the inner baffle 622 and the outer baffle 623, is designed as a flat surface for receiving and dispensing dye. It has a feed hole 625 to ensure the dye flows accurately into the target area, preventing waste or spillage. The mounting pin 626, designed as a fixing device, is located at the bottom of the sealing cover 621 to secure the various parts of the sealing assembly 62, ensuring stable operation throughout the dyeing process. The overall design is optimized, with comprehensive functions, suitable for various dyeing needs.

[0052] The inner baffle 622 is crescent-shaped, and the outer baffle 623 is fan-shaped. The adjacent surfaces of the inner baffle 622 and the outer baffle 623 are curved, and the distance between them is set to the diameter of the feed head 542. This configuration creates an arc-shaped gap between them, allowing the feed tube 54 and the feed head 542 to pass through when the rotating shaft 51 drives the dyeing box 61 to rotate. The adjacent surfaces of the inner baffle 622 and the outer baffle 623 are curved, and the distance between them is set to the diameter of the feed head 542.

[0053] The collecting surface 624 is set as a concave arc surface, which can prevent the dye from leaking out during the feeding process of the feeding head 542 and ensure the input. The lowest point of the concavity is set as the feeding hole 625.

[0054] In the operation of this utility model, the storage block 52 and the conveying pipe 54 are fixed inside the housing 1, and the rotating shaft 51 can drive the connecting rod 55 so that the dyeing box 61 rotates accordingly.

[0055] Staff members open the observation sliding door 2, slide the sealing cover 621, place the substance to be dyed into the dyeing box 61, and close the sealing cover 621 to complete the placement process. If multiple sets of substances need to be placed, the drive motor 3 can drive the rotating shaft 51 to rotate a certain angle to facilitate the placement of substances in the internal dyeing box 61.

[0056] When it is necessary to replenish the dyeing agent, the control of the drive cylinder 4 causes the movable cover 53 to move upward and open the storage block 52, so that the staff can replenish the dyeing agent into the storage chamber 521.

[0057] According to the test requirements, the staff can switch the control valve 543 to add an appropriate amount of dye or other substances to the corresponding dyeing box 61, and drive the dyeing box 61 to move under the appropriate feed pipe 54 by rotating the shaft 51. They can also control the heating plate 56 to heat the dyeing box 61 to a suitable temperature.

[0058] Although the present disclosure has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to the embodiments of the present disclosure, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present disclosure are within the scope of protection claimed by the present disclosure.
