[0001] This invention belongs to the field of medical device technology, and in particular relates to a cover plate device and a sample processing system. Background Technology

[0002] A glass slide specimen consists of a sample, a glass slide, and a coverslip. After the sample is fixed on the glass slide, the coverslip is placed on the glass slide to cover the sample. In the prior art, a slide preparation device is used to stain and fix the sample on the glass slide, and a coverslip device is used to place the coverslip on the glass slide to cover the sample to form a glass slide specimen. Both the slide preparation device and the coverslip device are standalone machines. In particular, the coverslip device is usually manually loaded into the coverslip device with the glass slide with the sample fixed on it or the glass slide basket carrying the glass slide, and then mounted. The mechanical automation performance is low. For example, Chinese patent CN212110871U discloses a highly efficient and stable intelligent slide sealing machine. The highly efficient and stable intelligent slide sealing machine includes a machine housing, the machine housing includes a base plate, the base plate is provided with a slide support device, the slide support device includes a linear guide rail, a support seat is slidably connected on the linear guide rail, the support seat is used to place a slide rack with several slides, and the slide rack needs to be placed manually on the support seat, so the degree of automation is low. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a cover sheet device capable of automatic feeding.

[0004] The second objective of this invention is to provide a sample processing system.

[0005] One of the objectives of this invention is achieved by the following technical solution: a cover plate device, comprising:

[0006] The housing assembly has a first opening;

[0008] The clamping assembly is used to clamp a slide basket; the first bearing assembly is used to drive the second bearing assembly to move the clamping assembly through the first opening between the material picking station outside the cover plate device and the first bearing station inside the cover plate device. The material picking station is used for the clamping assembly to clamp the slide basket loaded with glass slides, and the first bearing station is used for the clamping assembly to place the clamped slide basket loaded with glass slides.

[0009] In one embodiment, the first support component includes a first mounting plate and a first guide rail disposed on the first mounting plate, the first guide rail extending along a first direction, and the second support component being slidably connected to the first guide rail.

[0010] In one embodiment, the second support component includes a second mounting plate and a second guide rail disposed on the second mounting plate. The second guide rail extends along the first direction, and the second mounting plate is slidably connected to the first guide rail. The clamping component is slidably connected to the second guide rail.

[0011] In one embodiment, the transfer mechanism further includes a third carrier component;

[0012] The third bearing component includes a third mounting plate slidably connected to the second guide rail and a third guide rail disposed on the third mounting plate. The third guide rail extends along a second direction, and the clamping component is slidably connected to the third guide rail. The first direction and the second direction intersect.

[0013] In one embodiment, the cover glass device further includes a transfer mechanism and a slide processing mechanism. The slide processing mechanism is used to remove the slides in the slide basket, apply adhesive to the slides, and attach the cover glass to the adhesive-applied slides to form a slide specimen. A first transfer station and a second transfer station are provided on the movement trajectory of the transfer mechanism.

[0014] The clamping component is slidably connected to the second guide rail via the third bearing component to transport the empty slide basket to the first transfer station;

[0015] The transfer mechanism is used to transport an empty slide basket from the first transfer station to the second transfer station.

[0016] In one embodiment, the cover plate device further includes a conveying mechanism, on which the first bearing station is provided. The conveying mechanism is used to move to the first bearing station to receive the slide basket carrying the glass slide. The conveying mechanism is also used to transport the empty slide basket so that the clamping assembly can clamp the slide basket and transport the slide basket to the first transfer station.

[0017] In one embodiment, a transfer position is also provided on the movement trajectory of the conveying mechanism. The movement of the conveying mechanism causes the slides on the slide basket to move to the transfer position so that the slide processing mechanism can transfer the slides located at the transfer position.

[0018] In one embodiment, the coverslip device further includes a slide loading mechanism, which is used to clamp the empty slide basket located at the second transfer station, load the slide specimen into the empty slide basket, and then place the slide basket loaded with the slide specimen into the transfer mechanism.

[0019] In one embodiment, the slide loading mechanism is used to place the slide basket containing the slide specimen at the second transfer station of the transfer mechanism.

[0020] In one embodiment, the slide loading mechanism includes a storage component, a flipping component, and a pushing component;

[0021] The storage component is used to store glass slide specimens;

[0022] The flipping component is used to pick up the empty slide basket from the second transfer station and to drive the slide basket to flip from a first state with the slide pick-up and drop opening facing upwards to a second state with the slide pick-up and drop opening facing the storage component.

[0023] The pushing component is used to push the glass slide specimen on the storage component into the glass slide basket on the flipping component, which is in the second state;

[0024] The flipping component is also used to drive the slide basket to flip from the second state to the first state and place the slide basket containing the slide specimen into the transfer mechanism.

[0025] The second objective of this invention is achieved by the following technical solution: a sample processing system, comprising: a liquid-based slide preparation device and the aforementioned cover plate device, wherein the material handling station is located within the liquid-based slide preparation device.

[0026] Compared to existing technologies, the advantages of this invention are as follows: By setting a second supporting component movably connected to a first supporting component, and a clamping component connected to the second supporting component, the first supporting component drives the second supporting component to move the clamping component through the first opening between the material-picking station outside the cover plate device and the first supporting station inside the cover plate device. This allows the unloaded clamping component to move from the first supporting station inside the cover plate device to the material-picking station outside the cover plate device, clamp a slide basket carrying a glass slide, move from the material-picking station outside the cover plate device to the first supporting station inside the cover plate device, place the clamped slide basket at the first supporting station, and then move back to the material-picking station to clamp another slide basket. Therefore, the cover plate device provided by this invention allows the transfer mechanism to extend outside the cover plate device when a glass slide needs to be retrieved, retrieving a slide basket loaded with a glass slide, thus achieving automatic feeding; when a glass slide does not need to be retrieved, the transfer mechanism can be housed inside the cover plate device, resulting in a small space size that is beneficial for installation and transportation.

Detailed Implementation

[0038] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0039] Example 1:

[0040] Please see Figures 1 to 4This invention provides a cover plate device 100, including a housing assembly 10 and a transfer mechanism 20. The housing assembly 10 has a first opening 121. The transfer mechanism 20 includes a first support assembly 21, a second support assembly 22 movably connected to the first support assembly 21, and a clamping assembly 23 connected to the second support assembly 22. The clamping assembly 23 is used to clamp a slide basket 200. The first support assembly 21 is used to drive the second support assembly 22 to drive the clamping assembly 23 to reciprocate between a material picking station outside the cover plate device 100 and a first support station inside the cover plate device 100 through the first opening 121. The material picking station is used for the clamping assembly 23 to clamp a slide basket 200 loaded with slides, and the first support station is used for the clamping assembly 23 to place the clamped slide basket 200 loaded with slides. The material-retrieving station can be a location outside the coverslip device 100 where the slide basket 200 is placed. The slide basket 200, containing a sample, can be manually placed at this location. Alternatively, the material-retrieving station can be located within other devices, such as a slide-making device that loads the sample onto the slide. The material-retrieving station is used to place the slide basket, which in turn holds the sample-bearing slide. Therefore, the slide basket 200 can be automatically retrieved from the slide-making device. No limitation is placed on the material-retrieving station. It is understood that the relative positional relationship between the material-retrieving station and the first bearing station can be defined based on the housing assembly 10. In this embodiment, the housing assembly 10 encloses a receiving cavity, the first bearing station is located within the receiving cavity, and the material-retrieving station is located outside the receiving cavity and corresponds to the first opening 121.

[0041] In use, the first support component 21 drives the second support component 22 to move the clamping component 23 through the first opening 121 from inside the cover plate device 100 to the material picking station outside the cover plate device 100. After the clamping component 23 clamps the slide basket 200 carrying the glass slide, the first support component 21 drives the second support component 22 to move the clamping component 23 through the first opening 121 from the material picking station to the first support station inside the cover plate device 100. The clamping component 23 releases the clamped slide basket 200 carrying the glass slide, thus realizing the conveying of the slide basket 200.

[0042] By adopting the above technical solution, the second support component 22 is movably connected to the first support component 21, and the clamping component 23 is connected to the second support component 22. The first support component 21 drives the second support component 22 to drive the clamping component 23 to pass through the first opening 121 and reciprocate between the material picking station outside the cover plate device 100 and the first support station inside the cover plate device 100. This allows the unloaded clamping component 23 to move from the first support station inside the cover plate device 100 to the material picking station outside the cover plate device 100. After clamping the slide basket 200 carrying the glass slide, it moves from the material picking station outside the cover plate device 100 to the first support station inside the cover plate device 100. After placing the clamped slide basket 200 at the first support station, it can move again to the material picking station to clamp another slide basket 200. Therefore, the cover plate device 100 provided in this embodiment of the invention can automatically feed the slide basket 200 containing the slides when the slides need to be obtained, by extending the transfer mechanism 20 outside the cover plate device 100; when the slides do not need to be obtained, the transfer mechanism 20 can be housed inside the cover plate device 100, which has a small space size and is beneficial for installation and transportation.

[0043] Please see Figure 1 and Figure 5 The first support component 21 includes a first mounting plate 211 and a first guide rail 212 disposed on the first mounting plate 211. The first guide rail 212 extends along a first direction, and the second support component 22 is slidably connected to the first guide rail 212. In practical applications, the first support component 21 also includes a first power component 213, which drives the second support component 22 to slide along the first guide rail 212. In this embodiment, both the first mounting plate 211 and the first guide rail 212 are located within the accommodating cavity enclosed by the housing component 10, and the first mounting plate 211 is mounted on the housing component 10.

[0044] Please see Figure 5 The second support component 22 includes a second mounting plate 221 and a second guide rail 222 disposed on the second mounting plate 221. The second guide rail 222 extends along a first direction. The second mounting plate 221 is slidably connected to the first guide rail 212, and the clamping component 23 is slidably connected to the second guide rail 222. By slidably connecting the clamping component 23 to the second guide rail 222, a two-stage linkage of the clamping component 23 is achieved. By also extending the second guide rail 222 along the first direction, the distance the clamping component 23 moves along the first direction is extended. In practical applications, the second support component 22 also includes a second power component 223, which drives the clamping component 23 to slide along the second guide rail 222. It can be understood that in other embodiments, the second guide rail 222 may also extend along a third direction intersecting the first direction, so that the second power component 223 drives the clamping component 23 to move along the third direction. The extension direction of the second guide rail 222 is not limited here.

[0045] Please see Figure 1 , Figure 2 and Figure 5 The transfer mechanism 20 also includes a third support component 24; the third support component 24 includes a third mounting plate 241 slidably connected to the second guide rail 222 and a third guide rail 242 disposed on the third mounting plate 241. The third guide rail 242 extends along a second direction, and the clamping component 23 is slidably connected to the third guide rail 242. The first direction and the second direction intersect. In practical applications, the third support component 24 also includes a third power component 243, which drives the clamping component 23 to slide along the third guide rail 242. In this embodiment, the first direction is horizontal, the second direction is vertical, and the third support component 24 drives the clamping component 23 to perform lifting and lowering movements. In use, after the clamping component 23 moves from the cover plate device 100 to the material handling station, the third power component 243 drives the clamping component 23 to move downward along the third guide rail 242. After the clamping component 23 clamps the glass slide basket 200, the third power component 243 drives the clamping component 23 to move upward along the third guide rail 242.

[0046] Please see Figure 1 , Figure 2 and Figure 5 The coverslip device 100 also includes a transfer mechanism 30 and a slide processing mechanism 40. The slide processing mechanism 40 is used to remove the slides from the slide basket 200, apply adhesive to the slides, and attach the coverslips to the adhesive-applied slides to form a slide specimen. A first transfer station and a second transfer station are provided on the movement trajectory of the transfer mechanism 30. A clamping component 23 is connected to a second support component 22 to transport an empty slide basket 200 to the first transfer station. The transfer mechanism 30 is used to transport the empty slide basket 200 from the first transfer station to the second transfer station. In this embodiment, the clamping component 23 is slidably connected to the second guide rail 222 of the second support component 22, and the second power component 223 drives the clamping component 23 to move along the second guide rail 222 to transport the empty slide basket 200 to the first transfer station. Of course, as an alternative implementation, the clamping component 23 can be fixedly connected to the second bearing component 22, and the first power component 213 can drive the second bearing component 22 to move the clamping component 23 along the first guide rail 212 to transport the empty slide basket 200 to the first transfer station. In this embodiment, the slide processing mechanism 40 is located within the receiving cavity enclosed by the housing component 10, and the transfer mechanism 30 is at least partially located within the receiving cavity enclosed by the housing component 10.

[0047] In one implementation, the gripping assembly 23 is slidably connected to the second support assembly 22 to transport the empty slide basket 200 from the first support station to the first transfer station. Specifically, the gripping assembly 23 is slidably connected to the second guide rail 222 of the second support assembly 22. In practical applications, the gripping assembly 23 clamps the slide basket 200 carrying slides from the material handling station to the first support station. After the slides in the slide basket 200 have been removed by the slide processing mechanism 40, the gripping assembly 23 clamps the empty slide basket 200 from the first support station to the first transfer station.

[0048] Please see Figure 2 and Figure 3 The slide processing mechanism 40 includes a slide clamping assembly 41 and an adhesive cover plate assembly 42. The slide clamping assembly 41 is used to clamp the slide in the slide basket 200 and transport the clamped slide to the adhesive cover plate assembly 42. The adhesive cover plate assembly 42 is used to apply adhesive to the slide and attach the cover plate to the dispensing slide to form a slide specimen.

[0049] Please see Figure 3 and Figure 6 The cover plate device 100 also includes a transport mechanism 50, on which a first bearing station is provided. The transport mechanism 50 is used to move to the first bearing station to receive the slide basket 200 carrying the glass slide. By providing the transport mechanism 50, the transport mechanism 50 can move to the first bearing station, receive the slide basket 200 carrying the glass slide at the first bearing station, and then transport the slide basket 200 carrying the glass slide to the next station, such as the transfer station described below. In this embodiment, the transport mechanism 50 is at least partially located within the receiving cavity enclosed by the housing assembly 10.

[0050] In one implementation, the conveying mechanism 50 is also used to transport the empty slide basket 200 to the first bearing station. With this arrangement, after the slides in the slide basket 200 containing the slides are removed, the empty slide basket 200 can be transported to the first bearing station so that the gripping assembly 23 can grip the empty slide basket 200. In this embodiment, the conveying mechanism 50 transports the empty slide basket 200 to the first bearing station so that the gripping assembly 23 can grip the slide basket 200 and transport it to the first transfer station.

[0051] As one implementation, a transfer position is also provided on the movement trajectory of the transport mechanism 50. The transport mechanism 50 moves to move the slides on the slide basket 200 to the transfer position so that the slide processing mechanism 40 can transfer the slides located at the transfer position. In actual application, the transport mechanism 50 receives the slide basket 200 carrying the slides at the first bearing station, carries the slide basket 200 to the transfer position, the slide processing mechanism 40 transfers the slides in the slide basket 200 located at the transfer position, and then the transport mechanism 50 moves to transport the empty slide basket 200 from the transfer position to the first bearing station.

[0052] As one implementation, a second bearing station is also provided on the movement trajectory of the conveying mechanism 50. The conveying mechanism 50 is used to receive the slide basket 200 carrying glass slides, which is placed manually, at the second bearing station. By providing the second bearing station, when the conveying mechanism 50 moves to the second bearing station, the operator can place the slide basket 200 carrying glass slides onto the conveying mechanism 50, realizing manual loading. Thus, the cover slide device 100 provided in this embodiment of the invention can be both automatically and manually loaded. In practical applications, after the operator places the slide basket 200 carrying glass slides onto the conveying mechanism 50 located at the second bearing station, the conveying mechanism 50 moves to the transfer position so that the slide processing mechanism 40 can transfer the glass slides from the slide basket 200.

[0053] Please see Figure 1 and Figure 3 The housing assembly 10 includes a first housing 11 located on the main operating side. The first housing 11 has a second opening 111 corresponding to the second bearing station. The second opening 111 is used for manually placing a slide basket 200 carrying glass slides at the second bearing station. By placing the second opening 111 corresponding to the second bearing station on the main operating side, the operator is located on the main operating side, facilitating manual loading. In practical applications, the main operating side is located on the front side of the cover plate device 100.

[0054] Please see Figure 1 , Figure 2 and Figure 10 The housing assembly 10 also includes a second housing 12 and a third housing 13 respectively connected to both sides of the first housing 11, with a first opening 121 formed in the second housing 12. In this arrangement, the first opening 121 is located on the side adjacent to the main operating side. The first opening 121 allows the transfer mechanism 20 to extend out of the cover plate device 100 to grip the slide basket 200 carrying the glass slides, eliminating the need for manual intervention. Therefore, placing the first opening 121 on the side adjacent to the main operating side does not affect the operator's work. It is understood that in other embodiments, placing the first opening 121 on the side opposite to the main operating side is also possible.

[0055] Please refer to the figure. Figure 1 , Figure 2 , Figure 7 and Figure 8 The coverslip device 100 also includes a slide loading mechanism 60, which is used to grasp an empty slide basket 200 and load the slide specimen into the empty slide basket 200. By setting up the slide loading mechanism 60, automatic loading of slide specimens is achieved, improving the automation performance of the coverslip device 100. In this embodiment, the slide loading mechanism 60 is located within the receiving cavity enclosed by the housing assembly 10.

[0056] In one embodiment, the slide loading mechanism 60 is used to pick up an empty slide basket 200 located at the second transfer station and place the slide basket 200 loaded with slide specimens into the transfer mechanism 30. In a preferred embodiment, the slide loading mechanism 60 is used to place the slide basket 200 loaded with slide specimens into the second transfer station of the transfer mechanism 30. In use, the transfer mechanism 30 transports the empty slide basket 200 from the first transfer station to the second transfer station, the slide loading mechanism 60 picks up the empty slide basket 200 from the second transfer station, loads slide specimens into the empty slide basket 200 (the slide basket 200 may or may not be full), and then returns the slide basket 200 carrying the slide specimens to the second transfer station.

[0057] Please see Figure 7 and Figure 8 The slide loading mechanism 60 includes a storage component 61, a flipping component 62, and a pushing component 63. The storage component 61 stores slide specimens. The flipping component 62 picks up an empty slide basket 200 from the second transfer station and drives the slide basket 200 to flip from a first state with the slide pick-up / placement opening facing upwards to a second state with the slide pick-up / placement opening facing the storage component 61. The pushing component 63 pushes the slide specimens on the storage component 61 into the slide basket 200 in the second state on the flipping component 62. The flipping component 62 also drives the slide basket 200 to flip from the second state back to the first state and places the slide basket 200 containing the slide specimens onto the transfer mechanism 30. Through the cooperation of the storage component 61, the flipping component 62, and the pushing component 63, slide specimens are loaded into the empty slide basket 200 without manual intervention.

[0058] In one implementation, the flipping component 62 and the pushing component 63 are respectively disposed on opposite sides of the storage component 61. With this arrangement, the flipping component 62 is located on one side of the storage component 61, and the pushing component 63 is located on the other side. When the flipping component 62 flips the empty slide basket 200 so that the slide loading / unloading port faces the storage component 61, the pushing component 63 can conveniently push the slide from the storage component 61 into the slide basket 200 from the other side. Please refer to [link to relevant documentation]. Figure 7The flipping component 62 is located on the left side of the storage component 61, and the pushing component 63 is located on the right side of the storage component 61. When the flipping component 62 flips the slide basket 200 to the second state, the slide pick-up and drop opening is set to the right. At this time, the pushing component 63 can directly push the slide from right to left, thereby conveniently pushing the slide from the storage component 61 to the slide basket 200 located on its left.

[0059] Please see Figure 1 and Figure 6 The first housing 11 has a third opening 112. The transfer mechanism 30 is also used to transport the slide basket 200 containing the slide specimen through the third opening 112 and to the first unloading station for manual unloading of the slide basket 200. In practical applications, the transfer mechanism 30 transports the slide basket 200 containing the slide specimen from the second transfer station to the third opening 112, and then through the third opening 112 to the first unloading station, thus realizing manual unloading of the slide basket 200 containing the slide specimen. In this embodiment, the first unloading station is located on the main operating side of the coverslip device 100, which is convenient for operators to operate.

[0060] Please see Figure 1 , Figure 9 and Figure 10 The coverslip device 100 also includes an ejection mechanism 70. A second unloading station is provided on the movement trajectory of the transfer mechanism 30. A fourth opening 131 corresponding to the second unloading station is formed on the housing assembly 10. The transfer mechanism 30 is also used to transport the slide basket 200 containing the slide specimen to the second unloading station, so that the ejection mechanism 70 can push the slide basket 200 located at the second unloading station through the fourth opening 131 into the slide reading device located outside the coverslip device 100. Through this arrangement, the slide basket 200 containing the slide specimen is automatically pushed into the slide reading device.

[0061] In one implementation, a fourth opening 131 is formed on the third housing 13. With this arrangement, the fourth opening 131 is located adjacent to the main operating side of the cover plate device 100, and on opposite sides of the first opening 121. The fourth opening 131 allows the push-out mechanism 70 to push the slide basket 200 carrying the slide specimen to the slide reading device without manual intervention. Therefore, placing the fourth opening 131 adjacent to the main operating side does not affect the operator's work. It is understood that in other embodiments, placing the fourth opening 131 on the side opposite to the main operating side is also possible.

[0062] Example 2:

[0063] This embodiment provides a sample processing system, including a liquid-based slide preparation device and a cover plate device 100 as described in Embodiment 1, with a material handling station located within the liquid-based slide preparation device. Due to the use of the cover plate device 100 as described in Embodiment 1, when a slide basket 200 needs to be retrieved, the transfer mechanism 20 of the cover plate device 100 can pass through the first opening 121 to transport the slide basket 200 carrying the slides from the material handling station within the liquid-based slide preparation device to the first bearing station within the cover plate device 100; when the slide basket 200 does not need to be retrieved, the transfer mechanism 20 can be housed within the cover plate device 100, resulting in a small space size that facilitates installation and transportation.

[0064] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
