Description

Technical Field

[0001] This utility model relates to the field of cell preparation and staining technology, and in particular to a mechanism for adjusting the lateral spacing of the nozzles of a cell preparation and staining machine. Background Technology

[0002] A cell slide staining machine is an automated instrument used for cytological examination. It can efficiently and accurately prepare smears from human cell or tissue samples and stain them for observation and analysis by pathologists. Its main functions include preparing uniform and clear thin-layer smears from cell or tissue samples, staining the smears to enhance the visibility of cell structures, and automating the entire process from sample processing to slide preparation and staining, reducing human error. Its applications include screening for cervical cancer and breast cancer, as well as for cytological research and drug screening. The cell slide staining machine is an important tool for modern medical diagnosis and research. Its automation, efficiency, and accuracy provide strong support for pathological research and clinical diagnosis.

[0003] Cell slide staining machines utilize cell density differences to preferentially settle diseased cells onto glass slides, ensuring firm cell adhesion and preventing detachment. This achieves fully automated cell sedimentation and staining, preventing cross-contamination. The pipette tips in a cell slide staining machine are key components of the pipetting apparatus, primarily used for aspirating, transferring, and discharging liquid samples. Tip types include disposable tips to prevent cross-contamination, reusable tips that can be cleaned and disinfected, and reusable tips suitable for experiments requiring multiple pipetting operations. However, existing cell slide staining machines often have lateral movement mechanisms for the pipette tips that only allow for single-speed adjustment. This fails to adequately meet the demands for more precise movements, leading to reduced slide preparation accuracy and decreased practicality. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a lateral spacing adjustment mechanism for the gun head of a cell slide staining machine. It aims to improve the problem that the lateral movement mechanism of the gun head in the existing cell slide staining machine cannot meet the requirements when more precise movements are needed, resulting in reduced slide preparation accuracy and decreased practicality.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a lateral spacing adjustment mechanism for the nozzle of a cell slide staining machine, including a guide rail, a lead screw threadedly connected to the inner wall of the guide rail, a positioning frame fixedly connected to the right side of the guide rail, a first fixed disk fixedly connected to the right end of the lead screw, a second fixed disk fixedly connected to the right side of the first fixed disk, multiple transmission blocks fixedly connected to the outer wall of the second fixed disk, an internal gear ring slidably connected to the inner wall of the positioning frame, a sun gear provided on the inner wall of the internal gear ring, multiple planetary gears meshing with the outer wall of the sun gear, a planetary carrier fixedly connected to the left side of the planetary gear, a first transmission shaft fixedly connected to the left side of the planetary carrier, a second transmission shaft fixedly connected to the left side of the sun gear, transmission disks fixedly connected to the outer walls of both the first and second transmission shafts near their edges, transmission grooves formed on the inner wall of the transmission disks, and a disassembly mechanism slidably connected to the middle of the inner wall of the guide rail, the disassembly mechanism being used for quick disassembly and replacement of corresponding components.

[0006] As a further description of the above technical solution:

[0007] The disassembly mechanism includes a movable block, the outer wall of which is slidably connected to the inner wall of the guide rail. The inner wall of the movable block has a slot, and the inner wall of the slot has multiple sliding grooves. The inner wall of the sliding groove is slidably connected to a limit block. A sliding rod is fixedly connected to the opposite side of the limit block. A limit plate is fixedly connected to the opposite end of the sliding rod. A spring is provided on the outer wall of the sliding rod. A sliding column is slidably connected to the inner wall of the slot, and multiple mounting blocks are fixedly connected to the outer wall of the sliding column.

[0008] As a further description of the above technical solution:

[0009] A rubber sleeve is fixedly connected to the outer wall of the limiting plate, and a moving head is fixedly connected to the bottom of the sliding column.

[0010] As a further description of the above technical solution:

[0011] A telescopic rod is fixedly connected to the right side of the inner wall of the positioning frame, and an asynchronous motor is fixedly connected to the left end of the telescopic rod.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the guide rail is fixedly connected to multiple connecting plates, and the inner wall of the connecting plates is threaded with multiple screws.

[0014] As a further description of the above technical solution:

[0015] A washer is provided on the outer wall of the screw, and the inner wall of the washer is slidably connected to the outer wall of the screw.

[0016] As a further description of the above technical solution:

[0017] A nameplate is fixedly connected to the middle of the front side of the guide rail, and multiple screws are threaded onto the inner wall of the nameplate.

[0018] As a further description of the above technical solution:

[0019] The multiple limiting blocks are slidably connected at the same horizontal height, and the outer wall of the limiting block is in contact with the outer wall of the mounting block.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the asynchronous motor is pushed to slide within the positioning frame by starting the telescopic rod, thereby switching the transmission block to engage with the transmission grooves in the transmission disk on the outer wall of transmission shaft one and transmission shaft two respectively. By utilizing the difference in rotational speed of the planetary carrier and the output speed of the sun gear, the rotational speed of the screw driven by the fixed disk two through the fixed disk one is different, thus achieving the purpose of adjusting the precision while moving laterally, improving the film production accuracy and enhancing practicality.

[0022] 2. In this utility model, by inserting the sliding column into the slot and then rotating it, the chamfers of the mounting block and the limiting block are pressed together, allowing it to be squeezed into the sliding groove. When they are separated, the spring pushes the limiting block to reset it, thereby limiting the mounting block and achieving the purpose of quick installation, improving practicality and speeding up maintenance efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a transverse spacing adjustment mechanism for the nozzle of a cell slide staining machine, including a guide rail 1. A lead screw 7 is threaded onto the inner wall of the guide rail 1. The guide rail 1 guides structural movement. A positioning frame 4 is fixedly connected to the right side of the guide rail 1. A first fixing plate 8 is fixedly connected to the right end of the lead screw 7. A second fixing plate 9 is fixedly connected to the right side of the first fixing plate 8. Multiple transmission blocks 10 are fixedly connected to the outer wall of the second fixing plate 9. The positioning frame 4 is used to install the required structure. An internal gear ring 11 is slidably connected to the inner wall of the positioning frame 4. A sun gear 12 is provided on the inner wall of the internal gear ring 11. Multiple planetary gears 19 are meshed with the outer wall of the sun gear 12. A planetary carrier 13 is fixedly connected to the left side of the planetary gear 19. The planetary carrier 13 can transmit the rotation of the planetary gear 19. A drive shaft 11 is fixedly connected to the left side of the planetary carrier 13. A drive shaft 218 is fixedly connected to the left side of the sun gear 12. The drive shaft 11 can transmit the rotation of the planetary carrier 13. A drive disk 15 is fixedly connected to the outer wall of the drive shaft 11 and the drive shaft 218 near the edge. A drive groove 14 is opened on the inner wall of the drive disk 15. The drive shaft 218 can transmit the rotation of the sun gear 12. A disassembly mechanism 2 is slidably connected to the middle of the inner wall of the guide rail 1. The disassembly mechanism 2 is used to quickly disassemble and replace the corresponding parts. The drive groove 14 is used to engage with the drive block 10 to transmit rotation.

[0033] Specifically, the lead screw 7 is an important component for realizing linear motion conversion. When the lead screw 7 rotates, due to its threaded engagement with the inner wall of the guide rail 1, it can convert rotational motion into linear motion along the direction of the guide rail 1. The positioning frame 4 plays the role of fixing and supporting the subsequent transmission components, ensuring the stability of the entire transmission system. The transmission block 10 plays the role of transmitting power in the subsequent transmission process. The planetary carrier 13 plays the role of supporting the planetary gear 19 and enabling it to revolve around the sun gear 12. The transmission groove 14 can cooperate with other power sources or transmission components to transmit power to the entire adjustment mechanism, thereby realizing the adjustment of the lateral spacing of the gun head.

[0034] Please see the appendix Figure 3 - Appendix Figure 5 The disassembly mechanism 2 includes a movable block 209, the outer wall of which is slidably connected to the inner wall of the guide rail 1. The inner wall of the movable block 209 is provided with a slot 204, which is used to provide support for installation. The inner wall of the slot 204 is provided with multiple sliding grooves 206. The inner wall of the sliding groove 206 is slidably connected to a limit block 205. A sliding rod 202 is fixedly connected to the opposite side of the limit block 205. The sliding groove 206 is used to guide the limit block 205 to slide within it. A limit plate 201 is fixedly connected to the opposite end of the sliding rod 202. A spring 203 is provided on the outer wall of the sliding rod 202. The spring 203 can push the limit block 205 to reset. A sliding column 208 is slidably connected to the inner wall of the slot 204. Multiple mounting blocks 207 are fixedly connected to the outer wall of the sliding column 208. The limit plate 201 is used to limit the position of the sliding column 208.

[0035] Specifically, when the gun tip is worn, damaged, or needs to be replaced with a different specification gun tip to meet diverse experimental needs, the disassembly mechanism 2 can quickly replace the parts, avoiding the complex equipment disassembly and reassembly process, thus saving a lot of time and effort. The moving block 209 provides a reliable guide for the movement of the entire disassembly mechanism 2, and the slot 204 provides specific space for the installation and cooperation of other parts. The shape of the limiting block 205 is adapted to the slide 206 and can slide within the slide 206.

[0036] Please see the appendix Figure 4 - Appendix Figure 6 A telescopic rod 6 is fixedly connected to the right side of the inner wall of the positioning frame 4. An asynchronous motor 5 is fixedly connected to the left end of the telescopic rod 6. The telescopic rod 6 is used to push the asynchronous motor 5 to move. A rubber sleeve 17 is fixedly connected to the outer wall of the limiting plate 201. A moving head 16 is fixedly connected to the bottom of the sliding column 208. The rubber sleeve 17 can increase the friction of the outer wall of the limiting plate 201. Multiple connecting plates 23 are fixedly connected to the outer wall of the guide rail 1. Multiple screws 20 are threadedly connected to the inner wall of the connecting plate 23. The moving head 16 is used for slide preparation and dyeing.

[0037] Specifically, screw 20 can firmly fix the connecting plate 23 to other mounting structures, thereby stably installing the guide rail 1 on the equipment. This not only ensures the installation accuracy of the guide rail 1, but also enables the guide rail 1 to withstand greater external forces and vibrations during operation. The rubber sleeve 17 can play a buffering role, reducing the impact force on the limit plate 201 and other components, and extending their service life.

[0038] Please see the appendix Figure 2 - Appendix Figure 4 A nameplate 24 is fixedly connected to the center of the front side of the guide rail 1. Multiple screws 22 are threadedly connected to the inner wall of the nameplate 24. The nameplate 24 is used to help users understand the relevant information of the device. Multiple limit blocks 205 are slidably connected at the same horizontal height. The outer wall of the limit block 205 fits against the outer wall of the mounting block 207. A washer 21 is provided on the outer wall of the screw 20. The inner wall of the washer 21 is slidably connected to the outer wall of the screw 20. The washer 21 can increase the friction between the bottom of the screw 20 and the contact surface.

[0039] Specifically, the shim 21 increases the friction between the connecting plate 23 and the mounting structure, preventing the screw 20 from loosening due to vibration during equipment operation, thus ensuring the stability of the guide rail 1 installation. Simultaneously, the shim 21 also acts as a buffer, dispersing the pressure generated when the screw 20 is tightened, preventing damage to the connecting plate 23 or the mounting structure due to concentrated pressure. The screw 22 ensures that the nameplate 24 adheres to the guide rail 1, guaranteeing that the nameplate 24 will not loosen or fall off even if the mechanism vibrates during operation, thus ensuring long-term readability of the information.

[0040] Working principle: When the moving head 16 needs to be moved to the approximate position, the telescopic rod 6 is activated to pull the asynchronous motor 5, which can pull the internal gear ring 11 and the meshing structure within it to move within the positioning frame 4, thereby engaging the front transmission groove 14 and the transmission block 10. Then, the asynchronous motor 5 is activated to drive the sun gear 12, so that its power can be transmitted to the transmission disk 15 through the transmission shaft 18, and then to the fixed disk 9 through the transmission groove 14, thereby driving the lead screw 7 to rotate rapidly. After reaching the approximate position, when fine adjustment is required, the telescopic rod 6 is activated again to push the asynchronous motor 5 to move, so that the rear transmission groove 14 and the transmission block 10 are engaged, thereby transmitting the rotation of the planetary carrier 13 to the fixed disk 9, so that the lead screw 7 is decelerated and rotated for fine adjustment.

[0041] When the moving head 16 needs to be installed, first insert the sliding post 208 into the slot 204, then rotate the mounting block 207. At this time, the chamfered side of the mounting block 207 is in contact with the chamfered side of the limiting block 205, and the two press against each other, so that the limiting block 205 is squeezed into the sliding groove 206. When the mounting block 207 rotates and disengages from the limiting block 205, the spring 203 will push the limiting block 205 to slide, so that the mounting block 207 is limited within it. When disassembly is required, simply pull the limiting plate 201 to both sides so that it can pull the sliding rod 202, and then pull the limiting block 205. Then rotate the sliding post 208 to pull it out.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
