Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of glass slide sealing equipment, specifically to a tilting motion rolling and pressing slide covering device. Background Technology
[0002] In fields such as biological sample testing and pathological analysis, slide mounting is a crucial and fundamental procedure. Its purpose is to securely fix the sample on the slide and provide a long-term stable preservation environment for the sample by covering it with a coverslip and adding a sealing agent. At the same time, it ensures that the sample has good optical properties under a microscope so as to accurately obtain sample information.
[0003] Existing mounting equipment and methods are constantly evolving. For example, Chinese patent application number 202211474576.2 discloses a mounting device and method for mounting glass slides. The mounting device includes a base, a fixing assembly, a pipette arm, a sample injection assembly, and a slide pressing assembly. It achieves sample transfer through negative pressure adsorption and applies positive pressure to even out the glycerol between the sample and the glass slide. However, this approach still has certain limitations. In actual operation, when adsorbing samples under negative pressure, if the sample viscosity is high or the shape is irregular, the adsorption may be weak, causing the sample to fall off, or the adsorption force may be too strong, damaging the sample structure. During positive pressure application, it is difficult to accurately control the pressure and uniformity, easily leading to uneven glycerol distribution and air bubbles, affecting the mounting quality and subsequent sample observation. Furthermore, the device's structure is relatively complex, and the coordinated operation between components requires high control precision, increasing manufacturing and maintenance costs and limiting its widespread application.
[0004] Traditional mounting methods rely heavily on manual operation. Technicians must manually transfer the sample to a glass slide, add glycerin or other mounting agents drop by drop, and finally cover with a coverslip and gently press to distribute the glycerin evenly and remove air bubbles. This manual method is not only inefficient, but the quality of the mounting is also greatly dependent on the technician's skill and experience. Significant differences exist between operators in the accuracy of sample transfer, control of glycerin dosage, and the pressure and angle applied, easily leading to inconsistent mounting results and consequently affecting the accuracy of subsequent sample observation and analysis.
[0005] With the continuous advancement of technology, automated mounting equipment has gradually entered the market. However, apart from the patented solutions mentioned above, some existing automated mounting equipment uses mechanical gripping and other methods in the sample transfer process, which can easily damage some fragile and vulnerable samples. In operations such as glycerol spreading, there are also problems with precise control and poor results, making it difficult to meet the demand for high-quality mounting.
[0006] Therefore, developing a sealing device and method that can achieve sample transfer and sealing operations more efficiently and accurately, further improve sealing quality and efficiency, and at the same time simplify equipment structure and reduce costs has become an important problem that urgently needs to be solved in this field. Utility Model Content
[0007] The purpose of this invention is to provide a tilting motion rolling and pressing slide covering device to solve the problems mentioned in the background art. In actual operation, when negative pressure adsorbs samples, if the sample viscosity is high or the shape is irregular, the adsorption may be weak, causing the sample to fall off, or the adsorption force may be too great and damage the sample structure. During positive pressure application, it is difficult to accurately control the pressure and the uniformity of pressure application, which can easily lead to uneven glycerol distribution, air bubbles, and other problems, affecting the sealing quality and subsequent sample observation results.
[0008] To achieve the above objectives, this utility model provides a tilting motion rolling cover glass removal device, including a suction cup fixing head. The suction cup fixing head is rotatably connected to the connecting rod via a pin. The rotation amplitude of the suction cup fixing head is limited by a limiting screw and reset by a return spring. In the free state, the suction cup fixing head is lower on the left and higher on the right. The suction cup fixing head is provided with a vacuum suction cup for adsorbing cover glass slides.
[0009] A connecting plate is provided, the connecting rod is connected to the connecting plate, the connecting plate is mounted on the slider, the slider is slidably arranged along the guide rail, and the slider is driven to move linearly along the guide rail by a driving mechanism;
[0010] A coverslip box is disposed below the suction cup fixing head, and a plurality of coverslips are stacked inside the coverslip box.
[0011] This design features a suction cup holder that is rotatably connected to a connecting rod via a pin, allowing the suction cup holder to rotate. A limit screw restricts the rotation range of the suction cup holder, while a return spring ensures it returns to its initial free position (left lower, right higher) after rotation. A vacuum suction cup is mounted on the suction cup holder and used to pick up coverslips. A connecting rod connects to a connecting plate, which is fixed to a slider. The slider moves linearly along a guide rail under the action of a drive mechanism, thereby moving the suction cup holder. A coverslip holder is placed below the suction cup holder to store stacked coverslips. This structural design provides the basic motion and support framework for subsequent slide removal and coverlipping operations.
[0012] Preferably, the vacuum suction cup includes a left suction cup and a right suction cup. The bottom of the suction cup fixing head has an arc-shaped structure. When picking up the cover glass, the driving mechanism drives the suction cup fixing head to descend. The left suction cup first contacts and picks up the cover glass. The driving mechanism drives the suction cup fixing head to continue descending. The suction cup fixing head rolls along the bottom arc surface. The return spring is compressed. The left end of the suction cup fixing head tilts up, causing the cover glass to bend and tilt. When the driving mechanism continues to descend, the right suction cup picks up the cover glass, so that the entire cover glass fits against the bottom arc of the suction cup fixing head. After the adsorption is completed, the driving mechanism drives the suction cup fixing head to rise. The suction cup fixing head returns to its original position under the action of the return spring. The rolled and adsorbed cover glass is in a bent state.
[0013] This design further refines the slide retrieval process. The vacuum suction cup consists of a left and a right suction cup, with the bottom of the suction cup fixing head having an arc-shaped structure. During slide retrieval, the drive mechanism lowers the suction cup fixing head. The left suction cup first contacts and holds the coverslip. As the suction cup fixing head continues to descend, it rolls along the bottom arc surface, compressing the return spring. The left end of the suction cup fixing head tilts up, causing the coverslip to bend and tilt. As the drive mechanism continues to descend, the right suction cup holds the coverslip, at which point the entire coverslip fits snugly against the bottom arc of the suction cup fixing head. After adsorption is complete, the drive mechanism raises the suction cup fixing head. Under the action of the return spring, the suction cup fixing head returns to its original position. During this process, the rolled and adsorbed coverslip is in a bent state. By utilizing the sequential adsorption of the two suction cups and the rolling of the suction cup fixing head, the coverslip is bent and deformed, thus achieving separation from the next coverslip.
[0014] Preferably, during the sealing process, the suction cup fixing head moves above the glass slide and descends. When the left end of the cover glass slide falls onto the glass slide, the left and right suction cups disengage one after the other. As the driving mechanism drives the suction cup fixing head to continue descending, the suction cup fixing head rolls around the pin shaft, and the cover glass slide is pressed onto the glass slide from left to right by the bottom arc of the suction cup fixing head.
[0015] This section describes the slide sealing process. After the slide is removed, the suction cup fixing head moves above the slide and descends. When the left end of the coverslip lands on the slide, the left and right suction cups disengage sequentially. As the drive mechanism continues to lower the suction cup fixing head, it rolls around the pivot pin, pressing the coverslip onto the slide from left to right using the arc-shaped bottom of the suction cup fixing head. This rolling pressing method of the suction cup fixing head allows air between the coverslip and the slide to be gradually expelled, achieving a smooth and stable fit.
[0016] Preferably, the cover glass box consists of a box body, a right side plate, and a left side plate, which are connected by a locking and adjusting screw. The box body is provided with positioning pins near the right side plate and the left side plate on both sides, and a spring plunger is also provided. The spring plunger, in conjunction with the locking and adjusting screw, is used to adjust the inner width of the cover glass box.
[0017] This section describes the structure of the coverslip holder, which consists of a body, a right side panel, and a left side panel, connected by adjusting screws for easy disassembly and assembly. Pins are located near the side panels on both sides of the body for positioning, ensuring accurate installation. A spring plunger, in conjunction with the adjusting screws, allows adjustment of the inner width of the coverslip holder. By adjusting the screws to change the position of the side panels, the spring plunger provides elastic support and positioning, adapting to coverslips of different widths.
[0018] Preferably, the right side plate, the left side plate, the pin, and the spring plunger are all symmetrical in structure.
[0019] This feature further illustrates the structural characteristics of the coverslip holder: the right side plate, left side plate, pins, and spring plunger are symmetrically arranged. This symmetrical design ensures more even force distribution when adjusting the width and supporting the coverslip, guaranteeing that the coverslip remains stably centered within the holder and does not shift due to asymmetry in the two sides.
[0020] Preferably, the bottom surface of the box is inclined, with the left side lower than the right side, and is perpendicular to the movement guide rail of the suction cup fixing head. The cover glass is always in contact with the inner side of the box due to its own weight.
[0021] This feature describes the unique design of the bottom surface inside the coverslip holder, which is tilted to the left and up to the right, perpendicular to the movement guide rail of the suction cup fixing head. Because the coverslip has a certain weight, it will automatically align itself to the left under its own gravity inside the holder, maintaining contact with the inner side of the holder.
[0022] Preferably, the inner wall of the box has a longitudinal arc protrusion in the center, the longitudinal arc protrusion forms a 90.5° angle with the inner bottom surface of the box, the right side plate and the left side plate have grooves on their inner sides, and the longitudinal arc protrusion has a 0.5° angle with the direction of movement of the suction cup fixing head.
[0023] This section details the special structure of the cover glass holder's inner wall. A longitudinally curved boss is located in the center of the inner wall, forming a 90.5° angle with the bottom surface of the holder, which is 0.5° away from the direction of movement of the suction cup head. Grooves are located on the inner sides of the right and left panels. The design of the longitudinally curved boss and grooves reduces the contact area with the cover glass end face, and the special angle design ensures that the cover glass will not contact the left inner wall of the holder when it rises after being suctioned.
[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0025] This tilting motion rolling cover glass slide picking and sealing device achieves efficient and precise slide picking through the curved surface structure at the bottom of the suction cup fixing head and the sequential adsorption design of the double suction cups, avoiding slide stacking. During sealing, the cover glass slide is rolled and pressed together, effectively expelling air, preventing air bubbles, and improving sealing quality. The width of the cover glass box is adjustable and the bottom surface is tilted. Combined with the symmetrical structure and special inner wall design, it not only accommodates cover glass slides of different sizes but also uses gravity to achieve automatic positioning of the cover glass slides, improving the accuracy of slide picking and sealing while reducing friction between the cover glass slides and the box wall, thus protecting the cover glass slides. The overall structure is rationally designed, with all components working together. While ensuring functionality, the structure is simplified, reducing manufacturing and maintenance costs, and comprehensively solving the problems of slide stacking during picking, air bubbles during sealing, insufficient accuracy, and easy damage to cover glass slides in existing technologies.

[0033] 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.
[0034] This utility model provides a tilting motion rolling and pressing device for picking up and removing sheet covers, such as... Figure 1 , Figure 2 As shown, it includes a suction cup fixing head 1, which is rotatably connected to the connecting rod 2 via a pin 4. The suction cup fixing head 1 has its rotation range limited by a limiting screw 3 and is reset by a return spring 6. In its free state, the suction cup fixing head 1 is lower on the left and higher on the right. The suction cup fixing head 1 is equipped with a vacuum suction cup 5 for adsorbing cover glass slides.
[0035] Connecting plate 7, connecting rod 2 is connected to connecting plate 7, connecting plate 7 is mounted on slider 8, slider 8 is slidably set along guide rail 9, slider 8 is driven to linearly along guide rail 9 by drive mechanism;
[0036] Coverslip box 10 is located below suction cup fixing head 1, and several coverslips 11 are stacked inside coverslip box 10.
[0037] The suction cup fixing head 1 is rotatably connected to the connecting rod 2 via a pin 4, allowing the suction cup fixing head 1 to rotate. A limiting screw 3 limits the rotation range of the suction cup fixing head 1, while a return spring 6 allows it to return to its initial position (left lower, right higher) after rotation. A vacuum suction cup 5 is mounted on the suction cup fixing head 1 and is used to pick up coverslips 11. The connecting rod 2 is connected to a connecting plate 7, which is fixed to a slider 8. The slider 8 moves linearly along the guide rail 9 under the action of the drive mechanism, thereby moving the suction cup fixing head 1. A coverslip box 10 is placed below the suction cup fixing head 1 to store stacked coverslips 11. This structural design provides a basic motion and support framework for subsequent slide removal and cover operations. The basic architecture of the device was determined, enabling the suction cup fixing head 1 to be rotatable and movable, allowing it to move closer to and further away from the coverslip box 10 and to move between different positions. This lays the foundation for completing the slide picking and covering operations, ensures the stability and functionality of the overall structure of the device, and enables all components to work together to meet the basic structural requirements of the slide picking and covering device in the field of medical slide sealing.
[0038] In this embodiment, as Figure 3 As shown, the vacuum suction cup 5 includes a left suction cup 51 and a right suction cup 52. The bottom of the suction cup fixing head 1 has an arc-shaped structure. When picking up the slide, the driving mechanism drives the suction cup fixing head 1 to descend. The left suction cup 51 first contacts and picks up the cover glass 11. The driving mechanism drives the suction cup fixing head 1 to continue to descend. The suction cup fixing head 1 rolls along the bottom arc surface. The return spring 6 is compressed. The left end of the suction cup fixing head 1 tilts up, causing the cover glass 11 to bend and tilt. When the driving mechanism continues to descend, the right suction cup 52 picks up the cover glass 11, so that the entire cover glass 11 fits against the bottom arc of the suction cup fixing head 1. After the adsorption is completed, the driving mechanism drives the suction cup fixing head 1 to rise. The suction cup fixing head 1 returns to its original position under the action of the return spring 6. The rolled and adsorbed cover glass 11 is in a bent state.
[0039] The vacuum suction cup 5 consists of a left suction cup 5.1 and a right suction cup 5.2, with the bottom of the suction cup fixing head 1 having an arc-shaped structure. During slide removal, the drive mechanism lowers the suction cup fixing head 1. The left suction cup 5.1 first contacts and holds the coverslip 11. As the suction cup fixing head 1 continues to descend, it rolls along the bottom arc surface, compressing the return spring 6. The left end of the suction cup fixing head 1 tilts up, causing the coverslip 11 to bend and tilt. As the drive mechanism continues to descend, the right suction cup 5.2 holds the coverslip 11, at which point the entire coverslip 11 is in contact with the bottom arc of the suction cup fixing head 1. After adsorption, the drive mechanism raises the suction cup fixing head 1. Under the action of the return spring 6, the suction cup fixing head 1 returns to its original position. During this process, the rolled and adsorbed coverslip 11 is in a bent state. By utilizing the sequential adsorption of the two suction cups and the rolling of the suction cup fixing head 1, the coverslip 11 is bent and deformed, thus achieving separation from the next coverslip. The unique dual-suction cup rolling adsorption design effectively overcomes the problem of slide stacking that easily occurs during slide retrieval in existing technologies. The coverslip 11 bends during adsorption, creating gaps between adjacent coverslips, preventing adhesion, improving the accuracy and reliability of slide retrieval, ensuring that only one coverslip 11 is retrieved at a time, reducing the impact of slide retrieval errors on subsequent sealing operations, and improving the efficiency and stability of the entire sealing process.
[0040] Specifically, such as Figure 1 , Figure 2 As shown, during the sealing process, the suction cup fixing head 1 moves above the glass slide and descends. When the left end of the cover glass 11 falls onto the glass slide, the left suction cup 51 and the right suction cup 52 disengage one after the other. During the process of the driving mechanism driving the suction cup fixing head 1 to continue descending, the suction cup fixing head 1 rolls around the pin 4, and the cover glass 11 is pressed onto the glass slide from left to right by the bottom arc of the suction cup fixing head 1.
[0041] After the slide is retrieved, the suction cup fixing head 1 moves above the slide and descends. When the left end of the coverslip 11 lands on the slide, the left suction cup 5.1 and the right suction cup 5.2 disengage sequentially. As the drive mechanism continues to lower the suction cup fixing head 1, it rolls around the pin 4, pressing the coverslip 11 onto the slide from left to right using the arc at the bottom of the suction cup fixing head 1. This rolling pressing method of the suction cup fixing head 1 allows air between the coverslip 11 and the slide to be gradually expelled, achieving a smooth fit. This method overcomes the problem of air bubbles easily generated during traditional slide sealing. The left-to-right rolling pressing effectively squeezes out air between the coverslip 11 and the slide, preventing air bubble residue, improving the sealing quality, and making the sealed sample more suitable for microscopic observation and diagnosis. It reduces the number of unsuccessful sealing cases caused by air bubbles, thus improving the success rate and reliability of sealing.
[0042] Furthermore, such as Figure 5As shown, the coverslip box 10 consists of a box body 101, a right side plate 104, and a left side plate 105, which are connected by a locking and adjusting screw 106. The box body 101 is provided with positioning pins 103 near the right side plate 104 and the left side plate 105 on both sides, and also with spring plungers 102. The spring plungers 102, together with the locking and adjusting screw 106, are used to adjust the inner width of the coverslip box 10.
[0043] The coverslip holder 10 consists of a body 101, a right side plate 104, and a left side plate 105, connected by a locking adjusting screw 106 for easy disassembly and assembly. Pins 103 are located on both sides of the body 101 near the side plates for positioning, ensuring accurate installation of the side plates. A spring plunger 102, in conjunction with the locking adjusting screw 106, adjusts the inner width of the coverslip holder 10. By adjusting the screw to change the position of the side plates, the spring plunger 102 provides elastic support and positioning, adapting to coverslips 11 of different widths. The adjustable internal width design of the coverslip holder 10 ensures that the gap between the coverslips 11 and the side plates meets accuracy requirements, preventing the coverslips 11 from shaking or being squeezed inside the holder. Simultaneously, this design is compatible with coverslips 11 of different sizes, expanding the applicability of the device and meeting the diverse needs of different experimental and application scenarios for coverslip 11 specifications, thus improving the versatility and practicality of the device.
[0044] Furthermore, such as Figure 5 As shown, the right side plate 104, the left side plate 105, the pin 103, and the spring plunger 102 are all symmetrical in structure.
[0045] The right side plate 104, left side plate 105, pin 103, and spring plunger 102 are symmetrically arranged. This symmetrical design ensures that the coverslip holder 10 experiences more even force when adjusting its width and supporting the coverslip 11, guaranteeing that the coverslip 11 remains stably centered within the holder and does not shift due to asymmetry in the two sides. The symmetrical structure helps maintain the stable placement of the coverslip 11 within the holder, ensuring the relative accuracy of the coverslip 11 and the suction cup fixing head 1 in the slide-taking position, further improving slide-taking accuracy, and avoiding inaccurate slide-taking or damage to the coverslip 11 due to positional shift within the holder. This enhances the stability and reliability of the coverslip holder 10 structure, providing a solid foundation for slide-taking operations.
[0046] Furthermore, such as Figure 5 As shown, the bottom surface inside the box 101 is inclined, with the left side lower than the right side, and is perpendicular to the motion guide rail 9 of the suction cup fixing head 1. The cover glass 11 is always in contact with the inside of the box 101 due to its own weight.
[0047] The cover glass holder 10 features a unique design on its inner bottom surface, which is tilted from left to right and perpendicular to the motion guide rail 9 of the suction cup fixing head 1. Due to the weight of the cover glass 11, it automatically aligns to the left under its own gravity within the holder, maintaining contact with the inner side of the holder 101. This automatic positioning of the cover glass 11 using gravity ensures a fixed and accurate position each time a slide is retrieved, improving both the retrieval and sealing accuracy. This overcomes the shortcomings of existing technologies where the cover glass 11 is easily misaligned during retrieval, leading to lower sealing accuracy. It ensures that every retrieval and sealing operation is performed in the same accurate position, enhancing the consistency and quality stability of the sealing process.
[0048] Furthermore, such as Figure 4 As shown, a longitudinal arc protrusion 107 is provided in the center of the inner wall of the box 101. The longitudinal arc protrusion 107 forms a 905° angle with the inner bottom surface of the box 101. The inner sides of the right side plate 104 and the left side plate 105 are provided with grooves 108. The longitudinal arc protrusion 107 forms a 05° angle with the direction of movement of the suction cup fixing head 1.
[0049] A longitudinal arc-shaped protrusion 107 is provided in the center of the inner wall of the box body 101, forming a 905° angle with the bottom surface of the box, which is also a 0.5° angle with the direction of movement of the suction cup fixing head 1. Grooves 108 are provided on the inner sides of the right side plate 104 and the left side plate 105. The design of the longitudinal arc-shaped protrusion 107 and the groove 108 reduces the contact area with the end face of the coverslip 11, and the special angle design ensures that the coverslip 11 will not contact the left wall of the box when it rises after being suctioned. Reducing the contact area between the coverslip 11 and the box body 101 lowers the probability of friction and collision between the coverslip 11 and the box wall during the slide retrieval and rising process, avoiding damage to the coverslip 11, effectively protecting the coverslip 11, improving the integrity rate of the coverslip 11, and also reducing the problems of slide retrieval failure and reduced sealing quality caused by damage to the coverslip 11, ensuring the smooth operation of slide retrieval and sealing.
[0050] In use, the tilting motion rolling cover glass removal device of this utility model initially has the suction cup fixing head 1 in a free state with the left side lower than the right side under the action of the return spring 6, and the cover glass slides 11 are neatly stacked in the cover glass slide box 10. The cover glass slide box 10 consists of a box body 101, a right side plate 104, and a left side plate 105. The internal width is adjusted by locking the adjusting screw 106, the pin 103, and the spring plunger 102, and the bottom surface of the box body 101 is tilted with the left side lower than the right side, so that the cover glass slides 11 automatically move to the left under the action of gravity and contact the inside of the box body 101. At this time, the slider 8 drives the connecting plate 7, the connecting rod 2, and the suction cup fixing head 1 to the initial position, waiting for the working command.
[0051] Upon receiving the slide retrieval command, the drive mechanism activates, causing the slider 8 to move along the guide rail 9, thus moving the suction cup fixing head 1 towards the cover glass slide box 10 and lowering it. The bottom of the suction cup fixing head 1 has an arc-shaped structure and is rotatably connected to the connecting rod 2 via a pin 4. During the descent, the left suction cup 51 on the suction cup fixing head 1 first contacts and holds the cover glass slide 11. As the drive mechanism continues to drive the suction cup fixing head 1 downward, the suction cup fixing head 1 rolls along the bottom arc surface, the return spring 6 is compressed, and the left end of the suction cup fixing head 1 tilts up, thereby causing the cover glass slide 11 to bend and tilt up together. When the drive mechanism continues to descend to a specific position, the right suction cup 52 holds the cover glass slide 11, at which point the entire cover glass slide 11 fits into the bottom arc of the suction cup fixing head 1, completing the adsorption. After adsorption is completed, the drive mechanism drives the suction cup fixing head 1 to rise. Under the action of the return spring 6, the suction cup fixing head 1 gradually returns to the initial state. During this process, the cover glass 11 that is rolled and adsorbed is in a bent state. This bending allows the cover glass 11 to be effectively separated from the next cover glass, avoiding stacking and successfully completing the slide removal operation.
[0052] After the slide is retrieved, the drive mechanism moves the suction cup fixing head 1 above the slide. Then, the suction cup fixing head 1 begins to descend. When the left end of the coverslip 11 lands on the slide, the left suction cup 51 and right suction cup 52 disengage. As the drive mechanism continues to descend, the suction cup fixing head 1 rolls around the pivot pin 4, pressing the coverslip 11 onto the slide from left to right using the arc at the bottom of the suction cup fixing head 1. This rolling pressing method gradually removes air between the coverslip 11 and the slide, preventing air bubbles and ensuring a smooth and tight fit between the coverslip 11 and the slide, completing a high-quality sealing operation. After pressing, the suction cup fixing head 1 rises back to its initial position, awaiting the next working command. This cycle repeats continuously, achieving automatic batch sealing of slides.
[0053] The above clearly presents the complete working principle and process of the device. If you believe that any part of the explanation needs more detail, or if there is anything to add, please feel free to suggest it.
