Description

Technical Field

[0001] This application relates to the field of medical devices, specifically to an automatic strip feeding device. Background Technology

[0002] Currently, most nucleic acid extraction systems on the market use batch injection, and the extraction strips in these systems are typically picked up and transferred using a conveying mechanism and a gripping mechanism. However, current automated strip feeding devices can only perform single-line conveying, meaning that each column of extraction strips requires a corresponding conveying mechanism. As the demand for in-system storage increases, the queue of extraction strips needs to be expanded. Each expansion of the queue requires an additional conveying mechanism, resulting in poor scalability of the automated strip feeding device. Utility Model Content

[0003] This application provides an automatic extraction strip supply device, which can solve the problem of poor scalability of existing automatic extraction strip supply devices.

[0004] This application provides an automatic strip feeding device, including:

[0005] A storage mechanism forms a storage space for storing at least two extraction strips;

[0006] A progressive mechanism is movably connected to the storage mechanism. The progressive mechanism is used to move within the storage space, move to the corresponding position of the extraction bar, and abut against the extraction bar.

[0007] A gripping mechanism is disposed on the advancing mechanism and moves synchronously with the advancing mechanism within the storage space. It is used to grip the extraction bar that comes into contact with the advancing mechanism, and the extraction bar is transferred to the outside of the storage space by the gripping mechanism.

[0008] In some embodiments, the at least two extraction strips are arranged along a first direction, and the automatic extraction strip supply device includes a first driving component connected to the advancing mechanism. The first driving component is used to drive the advancing mechanism to move within the storage space along the first direction.

[0009] In some embodiments, the automatic extraction strip supply device further includes a first feedback component connected to the first drive component. The first feedback component is used to monitor the movement position of the advancing mechanism in the storage space in the first direction and feed it back to the first drive component.

[0010] In some embodiments, the first drive component is connected to the advancing mechanism via a conveyor belt, and the first feedback component is used to monitor the conveying distance of the conveyor belt in order to monitor the moving position of the advancing mechanism.

[0011] In some embodiments, the advancing mechanism includes a second driving component and an advancing push plate. The second driving component is connected to the advancing push plate and is used to drive the advancing push plate to move along a second direction and abut against the corresponding extraction strip to press the extraction strip.

[0012] In some embodiments, the advancing mechanism further includes a second feedback component connected to the advancing push plate, the second feedback component being used to monitor the contact state of the advancing push plate and provide feedback to the gripping mechanism.

[0013] In some embodiments, the gripping mechanism includes a third driving component and a gripping component, the third driving component being connected to the gripping component, and the third driving component being used to drive the gripping component to grip the extraction strip abutted by the progressive push plate.

[0014] In some embodiments, the grasping mechanism further includes a third feedback component connected to the grasping component, the third feedback component being used to monitor the grasping state of the grasping component and provide feedback to the third driving component.

[0015] In some embodiments, the gripping component is connected to the progressive pusher plate, the second driving component is used to drive the progressive pusher plate and the gripping component to move synchronously along the second direction, so that the progressive pusher plate abuts against the corresponding extraction strip, the third driving component is used to drive the gripping component to grip the extraction strip that abuts against the progressive pusher plate, and the second driving component is used to drive the progressive pusher plate and the gripping component to transfer the gripped extraction strip outside the storage space.

[0016] In some embodiments, the first direction and the second direction are perpendicular to each other.

[0017] The beneficial effects of the embodiments of this application are as follows:

[0018] In this embodiment, the automatic strip feeding device includes a storage mechanism, a delivery mechanism, and a gripping mechanism. The storage mechanism forms a storage space for storing at least two strips. The delivery mechanism is movably connected to the storage mechanism and moves within the storage space to the corresponding strip position and abuts against it. The gripping mechanism is disposed on the delivery mechanism and moves synchronously with it within the storage space to grip the strip that has abutted against it. The strip is then transferred out of the storage space via the gripping mechanism. By configuring the delivery mechanism to move within the storage space to the corresponding strip position and abut against it, this application allows one delivery mechanism to correspond to multiple strips. This eliminates the need to add additional delivery mechanisms when the storage space and the number of strips are increased, thereby improving the scalability of the automatic strip feeding device.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0029] This application provides an automatic strip feeding device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0030] like Figure 1 and Figure 2 As shown, the automatic extraction strip supply device 100 includes a storage mechanism 110, which forms a storage space 111 for storing at least two extraction strips 200. When the storage space 111 stores multiple extraction strips 200, the multiple extraction strips 200 can be arranged in multiple columns. The specific arrangement of the extraction strips 200 can be selected and adjusted according to actual design requirements, and no special restrictions are imposed here.

[0031] like Figure 1 As shown, the automatic strip feeding device 100 includes a advancing mechanism 120, which is movably connected to the storage mechanism 110. The advancing mechanism 120 is used to move within the storage space 111, moving to the corresponding position of the strip 200 and abutting against it. That is, the advancing mechanism 120 can move within the storage space 111 to the position corresponding to any strip 200 and abut against it, so as to facilitate the grasping of the strip 200.

[0032] The automatic strip feeding device 100 includes a gripping mechanism 130, which is disposed on the advancing mechanism 120 and moves synchronously with the advancing mechanism 120 within the storage space 111. The gripping mechanism 130 is used to grip the strip 200 that abuts against the advancing mechanism 120, and the strip 200 is transferred outside the storage space 111 by the gripping mechanism 130. That is, when the gripping mechanism 130 grips the strip 200 in the storage space 111, it prioritizes gripping the strip 200 that abuts against the advancing mechanism 120, and after gripping, transfers the corresponding strip 200 outside the storage space 111 for use.

[0033] In this embodiment, the advancing mechanism 120 is configured to move within the storage space 111 to the position corresponding to any extraction bar 200 and abut against it, so that one advancing mechanism 120 can correspond to multiple extraction bars 200. This means that when the storage space 111 and the extraction bars 200 are increased, there is no need to add an additional advancing mechanism 120, thereby improving the scalability of the automatic extraction bar supply device 100.

[0034] In some embodiments, such as Figure 1 As shown, at least two extraction strips 200 are arranged along the first direction X. The automatic extraction strip supply device 100 includes a first drive assembly 140, which is connected to the advancing mechanism 120. The first drive assembly 140 is used to drive the advancing mechanism 120 to move along the first direction X within the storage space 111. That is, the first drive assembly 140 is used to drive the advancing mechanism 120 to move along the arrangement direction of the extraction strips 200, so as to realize the one-to-one multi-functionality of the advancing mechanism 120.

[0035] Optionally, the automatic strip feeding device 100 further includes a first feedback component 150, which is connected to the first drive component 140. The first feedback component 150 is used to monitor the movement position of the advancing mechanism 120 in the storage space 111 along the first direction X and feeds it back to the first drive component 140. That is, when the first drive component 140 drives the advancing mechanism 120 to move along the first direction X in the storage space 111, the first feedback component 150 is used to monitor the movement position of the advancing mechanism 120 in real time to determine whether the advancing mechanism 120 has moved to the target position, and feeds back the monitoring result to the first drive component 140 so that the first drive component 140 can continue to drive or stop driving.

[0036] In some embodiments, such as Figure 3 As shown, the first drive component 140 is connected to the advancing mechanism 120 via a conveyor belt, and the first feedback component 150 is used to monitor the conveying distance of the conveyor belt in order to monitor the moving position of the advancing mechanism 120. That is, the moving position of the advancing mechanism 120 can be directly obtained from the conveying distance of the conveyor belt, and real-time monitoring of the moving position of the advancing mechanism 120 can be achieved by monitoring the conveying distance of the conveyor belt.

[0037] The first drive component 140 and the first feedback component 150 are located at opposite ends of the conveyor belt. The advancing mechanism 120 moves between the first drive component 140 and the first feedback component 150 under the drive of the conveyor belt. A slide rail is provided below the advancing mechanism 120, extending along the first direction X. The first drive component 140 drives the advancing mechanism 120 to move along the slide rail. The slide rail effectively limits the sliding direction of the advancing mechanism 120, preventing the advancing mechanism 120 from deviating during the sliding process.

[0038] It should be noted that, in addition to conveyor belts, the first drive assembly 140 can also use other conveying methods, such as chains, without any special restrictions.

[0039] In some embodiments, such as Figure 4 As shown, the advancing mechanism 120 includes a second driving component 121 and an advancing push plate 122. The second driving component 121 is connected to the advancing push plate 122. The second driving component 121 drives the advancing push plate 122 to move along the second direction Y and abut against the corresponding extraction bar 200 to press the extraction bar 200. That is, the second direction Y is the direction of the column where the corresponding extraction bar 200 is located. Under the action of the second driving component 121, the advancing push plate 122 moves along the second direction Y until it abuts against and presses against the corresponding extraction bar 200, so as to facilitate the gripping by the gripping mechanism 130.

[0040] The second drive assembly 121 is connected to the advancing push plate 122 via a conveyor belt. The second drive assembly 121 is located at one end of the conveyor belt, and the advancing push plate 122 moves along the second direction Y under the drive of the conveyor belt. The advancing mechanism 120 is provided with a slide rail that extends along the second direction Y. The second drive assembly 121 drives the advancing push plate 122 to move along the slide rail. The slide rail effectively limits the sliding direction of the advancing push plate 122 and prevents the advancing push plate 122 from deviating during the sliding process.

[0041] Optionally, the advancing mechanism 120 further includes a second feedback component 123, which is connected to the advancing push plate 122. The second feedback component 123 is used to monitor the contact state of the advancing push plate 122 and feed it back to the gripping mechanism 130. That is, the second feedback component 123 is used to monitor the contact between the advancing push plate 122 and the corresponding extraction bar 200 during the movement along the second direction Y, and feeds back the monitored result to the gripping mechanism 130.

[0042] The second feedback component 123 is equipped with a spring structure. When the advancing push plate 122 comes into contact with the corresponding extraction bar 200, the spring structure will be compressed. When the compression reaches a preset threshold, it indicates that the advancing push plate 122 and the corresponding extraction bar 200 are in stable contact. At this time, the second feedback component 123 feeds back the monitoring result to the gripping mechanism 130. After receiving the feedback result, the gripping mechanism 130 begins to grip the extraction bar 200.

[0043] In some embodiments, such as Figure 5As shown, the gripping mechanism 130 includes a third driving component 131 and a gripping component 132. The third driving component 131 is connected to the gripping component 132, and is used to drive the gripping component 132 to grip the extraction bar 200 that is abutted by the advancing push plate 122. That is, when the gripping mechanism 130 receives the feedback result from the second feedback component 123, the third driving component 131 will drive the gripping component 132 to hook the corresponding extraction bar 200 upwards.

[0044] It should be noted that the grasping component 132 in this embodiment of the application adopts the method of hooking from below the extraction bar 200. Therefore, when the third driving component 131 drives the grasping component 132 to grasp, it will drive the grasping component 132 to rise in the vertical direction until the grasping component 132 grasps the corresponding extraction bar 200.

[0045] In some embodiments, the gripping mechanism 130 further includes a third feedback component 133, which is connected to the gripping component 132. The third feedback component 133 is used to monitor the gripping status of the gripping component 132 and feed it back to the third driving component 131. That is, the third feedback component 133 is used to monitor whether the gripping component 132 has gripped the extraction bar 200 and feeds the monitoring result back to the third driving component 131. If the gripping component 132 is detected to have gripped the extraction bar 200, the third driving component 131 stops driving. If the gripping component 132 is detected not to have gripped the extraction bar 200, the third driving component 131 can continue to drive the gripping component 132 to perform gripping. At the same time, the third feedback component 133 can also monitor whether the gripping component 132 stably grips the corresponding extraction bar 200, so as to facilitate the subsequent transfer operation of the extraction bar 200.

[0046] Optional, such as Figure 4 As shown, the gripping component 132 is connected to the advancing push plate 122. The second driving component 121 is used to drive the advancing push plate 122 and the gripping component 132 to move synchronously along the second direction Y, so that the advancing push plate 122 abuts against the corresponding extraction strip 200. The third driving component 131 is used to drive the gripping component 132 to grip the extraction strip 200 that abuts against the advancing push plate 122. The second driving component 121 is used to drive the advancing push plate 122 and the gripping component 132 to transfer the gripped extraction strip 200 outside the storage space 111.

[0047] The advancing pusher 122 and the gripping component 132 move synchronously along the second direction Y. When the advancing pusher 122 comes into contact with the corresponding extraction strip 200, the gripping component 132 also reaches the gripping position. The third drive component 131 then directly drives the gripping component 132 to grip the extraction strip 200 closest to the advancing pusher 122. After gripping, the second drive component 121 then drives the advancing pusher 122 and the gripping component 132 to move synchronously in the opposite direction to the second direction Y, so as to transfer the extraction strip 200 gripped by the gripping component 132 outside the storage space 111.

[0048] In some embodiments, the first direction X and the second direction Y are perpendicular to each other. When the extraction strips 200 are arranged in multiple columns, the first direction X refers to the arrangement direction of the multiple columns of extraction strips 200, and the second direction Y refers to the arrangement direction of the extraction strips 200 in each column. By setting the first direction X and the second direction Y to be perpendicular, it is helpful to design the arrangement of the positions of each mechanism in the automatic extraction strip supply device 100, so as to maximize the space utilization of the automatic extraction strip supply device 100 and facilitate the expansion of the automatic extraction strip supply device 100.

[0049] Specifically, the automatic strip feeding device 100 in this embodiment of the application mainly includes the following steps when grasping the strip 200:

[0050] First, the first driving component 140 drives the advancing mechanism 120 and the grasping mechanism 130 to move synchronously along the first direction X. The first feedback component 150 monitors the moving position of the advancing mechanism 120 and the grasping mechanism 130 in real time until the advancing mechanism 120 and the grasping mechanism 130 move to the position of the column where the target extraction bar 200 is located, and then the first driving component 140 stops driving.

[0051] Next, the second drive component 121 drives the progressive push plate 122 and the gripping mechanism 130 to move synchronously along the second direction Y. The second feedback component 123 monitors the movement position of the gripping mechanism 130 of the progressive push plate 122 in real time until the progressive push plate 122 abuts against the extraction bar 200 of the corresponding column, and the compression of the spring structure in the second feedback component 123 reaches a preset threshold, indicating that the progressive push plate 122 presses the corresponding extraction bar 200.

[0052] Then, the third drive component 131 drives the gripping component 132 to move upward until the gripping component 132 hooks the extraction bar 200 that is close to the advancing push plate 122, and the third feedback component 133 monitors whether the gripping component 132 has grabbed the extraction bar 200.

[0053] Finally, the second drive assembly 121 drives the advancing push plate 122 and the gripping mechanism 130 (including the gripped extraction strip 200) to exit in a direction opposite to the second direction Y, so as to transfer the gripped extraction strip 200 outside the storage space 111, thereby completing the gripping action of the extraction strip 200.

[0054] The above provides a detailed description of an automatic strip feeding device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
