[0002] Before biochemical analysis, samples (liquids required for biochemical reactions) need to be processed. At present, in some fully automatic medical analysis systems, when processing samples, one-dimensional codes (bar codes) or two-dimensional codes are pasted on test tubes to mark the type, source and other information of samples in different test tubes. At the same time, a scanning device is required to identify the one-dimensional code or two-dimensional code on the test tube, so that the fully automatic medical analysis system can count and classify the detection information of the samples.

[0003] However, the existing code scanning device uses an automatic zoom code scanner, which is relatively expensive; the code scanning operation is cumbersome, the scanning time is long, and the scanning efficiency is low; in addition, the existing code scanning device has poor compatibility and is difficult to be compatible with identification codes of different formats and types.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be noted that when a component is referred to as being "fixed to" or "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. The term "and / or" as used herein includes all and any combinations of one or more of the relevant listed items.

[0029] See also Figures 1 to 3 , the embodiment of the present application provides a sample processing device 1000, which can be used in a biochemical reaction system, for example, to perform operations such as pipetting and liquid separation on the liquid required for the biochemical reaction. The sample container (such as a reagent tube, a centrifuge tube, etc.) is provided with an identification code (such as a one-dimensional code or a two-dimensional code) for recording sample information in advance. During the process of pipetting and liquid separation, it is necessary to quickly and accurately read the sample information recorded on the identification code. Specifically, the sample processing device 1000 includes: a mounting table 200, a carrying module 300 and a code scanning device 100, and the carrying module 300 and the code scanning device 100 are both arranged on the mounting table 200. The carrying module 300 includes a plurality of parallel-arranged carrying rails 301, a channel 302 is formed between two adjacent carrying rails 301, and the two adjacent carrying rails 301 and the channel 302 constitute a carrying structure 303, and the carrying structure 303 is used to carry the sample rack 10, and the sample rack 10 can be placed on the aforementioned sample container. The code scanning device 100 is located at one end of the bearing structure 303. The code scanning device 100 can be used to scan the identification code on the sample rack 10, thereby quickly and accurately reading the sample information to ensure accurate distribution of the liquid. In addition, the sample processing device 1000 may also include a controller (not shown), which is used to control the bearing module 300 and the code scanning device 100 to work together.

[0030] like Figure 1 As shown, the mounting platform 200 is provided with serial number markings at the entrance end of each channel 302 to facilitate loading and unloading operations of the sample rack 10. For example, in this embodiment, the number of channels 302 is 36, and the numbers 1 to 36 are marked at the entrance ends of the corresponding channels 302.

[0031] Please refer to Figures 4 to 6, the code scanning device 100 includes a guide rail 1, a slider assembly 2, a slider 3 and a code scanning assembly 4. The guide rail 1 can be mounted on a mounting table 200. The slider assembly 2 is slidably arranged on the guide rail 1. The slider 3 has a slide groove 31, and the extension direction of the slide groove 31 is the same as the extension direction a of the guide rail 1, that is, the slide groove 31 is arranged substantially parallel to the guide rail 1, the slider assembly 2 is slidably arranged in the slide groove 31, and the slider 3 is slidably arranged on the guide rail 1 through the slider assembly 2. The code scanning assembly 4 is arranged on the slider 3, and the maximum stroke of the code scanning assembly 4 is the sum of the stroke of the guide rail 1 and the stroke of the slide groove 31. The code scanning assembly 4 is slidably arranged on the guide rail 1 through the slider 3 and the slider assembly 2, and at the same time, the slider 3 can also move relative to the slider assembly 2, so that the guide rail 1 and the slider 3 form a double-layer track structure, and the moving stroke of the code scanning assembly 4 is equal to the superimposed stroke of the guide rail 1 and the slide groove 31. By designing a movable code scanning component 4, mobile code scanning can be realized, reducing the requirement for automatic zoom of the code scanning device 100, thereby reducing costs; at the same time, through the double-layer track superposition design of the guide rail 1 and the sliding member 3, the scanning distance of the code scanning component 4 can be effectively extended to adapt to different application scenarios.

[0032] like Figure 1 and Figure 3 As shown, the guide rail 1 is provided at one end of all the bearing structures 303, and the extension direction a of the guide rail 1 is perpendicular to the extension direction b of the channel 302, so that the code scanning device 100 is located at the entrance end of the bearing structure 303. When the sample rack 10 is pushed onto the bearing structure 303 for loading, the code scanning device 100 can be started to scan the code. Specifically, the guide rail 1 can be a linear guide rail, which can realize the movement of the entrance end of all the bearing structures 303 of the code scanning component 4, and realize mobile code scanning.

[0033] In some embodiments, the mounting platform 200 has a groove 201, and the guide rail 1 is installed in the groove 201. The guide rail 1 is sunk into the mounting platform 200 so that the guide rail 1 can be lower than the upper surface of the mounting platform 200. At this time, after the sample rack 10 is pushed into the supporting structure 303, the guide rail 1 is lower than the bottom surface of the sample rack 10, and will not affect the pushing in and pulling out of the sample rack 10.

[0034] In some embodiments, after the guide rail 1 is installed in the groove 201, the opposite ends of the guide rail 1 may be provided with limiting structures (not shown) to prevent the slider assembly 2 from accidentally falling off the guide rail 1. Alternatively, the length of the groove 201 is designed to be substantially the same as the length of the guide rail 1, so that the inner walls of the groove 201 corresponding to the opposite ends of the guide rail 1 can serve as limiting structures to block the slider assembly 2.

[0035] like Figure 5 As shown, the slider assembly 2 includes a first slider 21 and a second slider 22 connected to the first slider 21 , the first slider 21 is slidably disposed on the guide rail 1 , and the second slider 22 is slidably disposed in the slide groove 31 .

[0036] In some embodiments, the first sliding block 21 has a first track groove 23 , and the first sliding block 21 is engaged on the guide rail 1 through the first track groove 23 to be slidably connected with the guide rail 1 .

[0037] In some embodiments, the second slider 22 is embedded in the slide groove 31 , and the second slider 22 and the slide groove 31 may be designed to have a structure that cooperates with each other, so that the second slider 22 can slide smoothly in the slide groove 31 .

[0038] In some embodiments, the first slider 21 and the second slider 22 are detachable structures, and can be specifically connected by screws to facilitate the assembly of the guide rail 1 and the sliding member 3 .

[0039] like Figure 5 and Figure 6 As shown, first limiting posts 33 are provided at opposite ends of the slide slot 31 . By providing the two first limiting posts 33 , the travel of the slider assembly 2 can be limited to prevent the slider assembly 2 from escaping from the slide slot 31 .

[0040] In some embodiments, the first limiting column 33 may be a limiting screw.

[0041] like Figures 4 to 6 As shown, combined Figure 1 and Figure 2 The code scanning device 100 further includes a non-return assembly 5 disposed on the sliding member 3. When the slider assembly 2 drives the code scanning assembly 4 to move, the non-return assembly 5 is used to clamp on the non-return portion 202 disposed on the mounting platform 200 (such as Figure 2 The slider assembly 2 and the barcode scanning assembly 4 are fixed to further realize stable barcode scanning of the barcode scanning assembly 4 and improve the quality of barcode scanning. The barcode scanning assembly 4 can be connected to the controller through a power cord (not shown). When the barcode scanning assembly 4 moves a long distance, the power cord may pull the barcode scanning assembly 4, causing the barcode scanning assembly 4 to move back, and the barcode scanning stability is poor. By adding a non-return assembly 5, when the non-return assembly 5 is engaged with the non-return portion 202, the barcode scanning assembly 4 can be fixed, and the stability of the barcode scanning assembly 4 during the barcode scanning process can be improved.

[0042] In some embodiments, Figure 2 , Figure 6 and Figure 7As shown, the non-return assembly 5 includes: an elastic member 51, a non-return block 52 and a rotating shaft 53. One end of the elastic member 51 is arranged on the sliding member 3, the rotating shaft 53 is arranged on the sliding member 3, one end of the non-return block 52 is rotatably connected to the rotating shaft 53, and the other end can abut against the end of the elastic member 51 away from the sliding member 3. Figure 2 As shown, when the slider assembly 2 drives the code scanning assembly 4 to slide to the right (i.e., the direction in which the identification number of the channel 302 is from 1 to 36) to the position of the corresponding check portion 202, the check portion 202 will abut the check block 52, so that the check block 52 can rotate counterclockwise around the rotation axis 53, and the free end of the check block 52 abuts against the elastic member 51, compressing the elastic member 51. When the slider assembly 2 drives the code scanning assembly 4 to continue to move to the right, the check block 52 leaves the check portion 202, and the check block 52 rotates clockwise and resets under the elastic force of the elastic member 51. At this time, under the pulling force of the power cord, the code scanning assembly 4 moves to the left (i.e., the direction in which the identification number of the channel 302 is from 36 to 1), so that the check block 52 is stuck on the check portion 202 and stops moving. At this time, the slider assembly 2 and the code scanning assembly 4 are fixed, and the code scanning operation can be performed. When the code scanning is completed, the check block 52 can be pressed close to the end of the elastic member 51 to make the check block 52 rotate counterclockwise around the rotating axis 53. At this time, the free end of the check block 52 compresses the elastic member 51 to unlock it, and the code scanning component 4 can be smoothly pushed to the left to complete the resetting of the code scanning component 4. For example, the resetting of the code scanning component 4 can be achieved by pulling the power cord on the code scanning component 4.

[0043] In some embodiments, the end of the carrying rail 301 close to the code scanning device 100 can serve as the non-return portion 202 to apply external force to the non-return assembly 5 without the need to additionally provide the non-return portion 202 .

[0044] In some embodiments, the non-return assembly 5 further includes a second limiting column 54 disposed on the sliding member 3, and the second limiting column 54 is used to limit the rotation stroke of the non-return block 52. Specifically, the second limiting column 54 can be a limiting screw.

[0045] It is understandable that in other embodiments, the function of fixing the slider assembly 2 can also be achieved by adsorbing the non-return component. Specifically, the non-return component can include a first magnetic component (not shown) provided on the sliding member 3, and a second magnetic component (not shown) is provided at a corresponding position of the mounting platform 200. The first magnetic component can adsorb the second magnetic component, and the slider assembly 2 can be fixed by the magnetic adsorption force. After the code scanning is completed, the code scanning component 4 can be pushed by hand to move in the opposite direction to separate the first magnetic component from the second magnetic component to release the adsorption force and reset the code scanning component 4. It is also understandable that in other embodiments, the non-return component can also be a structural component such as a plunger or a screw. When the code scanning component 4 is moved into place, the sliding part 3 can be fixed to the mounting platform 200 by a structural component such as a plunger or a screw to fix the code scanning component 4.

[0046] like Figure 5 and Figure 6 As shown, the code scanning component 4 includes: a fixing frame 41 arranged on the sliding member 3 and a code scanner 42 arranged on the fixing frame 41, and the working surface of the code scanner 42 faces the sample rack 10 on the supporting structure 303. When the sample rack 10 is pushed into the supporting structure 303, the controller controls the code scanner 42 to scan the sample rack 10.

[0047] When in use, the sample rack 10 can be pulled out and pushed on the supporting structure 303 to complete loading and unloading. When the sample rack 10 is pushed into the corresponding supporting structure 303 for loading, the controller controls the barcode scanner 42 to open and scan the sample rack 10. Because the barcode scanner 42 has a fixed focal length and depth of field, when scanning the sample rack 10 on the channels 302 numbered 1-6, the barcode scanner component 4 is on the far left (such as Figure 1 When it is necessary to scan the sample rack 10 on the channel 302 labeled 7-12, the code scanning component 4 is manually pushed to the channel 302 position labeled 5 (as shown); Figure 2 When it is necessary to scan the sample racks 10 on the channels 302 labeled 12-18, the code scanning component 4 is manually pushed to the channel 302 labeled 10. The travel of the guide rail 1 and the sliding member 3 can be set according to the number of actual channels 302 to achieve the code scanning operation of the sample racks 10 in all channels 302. During the code scanning process, the process of the left and right movement, locking and unlocking of the code scanning component 4 is specifically described above, and no further details are given here.

[0048] The sample processing device 1000 provided in the embodiment of the present application can realize mobile scanning through the structural design of the scanning device 100, and further realize the scanning operation of the sample rack 10 at different positions, reduce the requirement of automatic zoom of the scanner 42, and reduce the cost of the scanning device 100; in the scanning device 100, the double-layer track design of the guide rail 1 and the sliding member 3 is used to extend the scanning distance, so that the scanning stroke of the scanning component 4 is equal to the sum of the strokes of the guide rail 1 and the sliding member 3; the scanning component 4 is connected to the controller through a power cord. When the scanning component 4 moves a long distance, the power cord may pull the scanning component 4, causing the scanning component 4 to move, and the scanning stability is poor. By adding a non-return component 5 and cooperating with the non-return portion 202 on the mounting table 200, the scanning component 4 can be fixed when needed to improve the stability of the scanning component 4 during the scanning process.

[0049] In addition, the code scanning device 100 can be integrated with other automated workstations to improve the working efficiency of the overall sample processing equipment 1000; in a specific pipetting workstation, the code scanning device 100 can realize code scanning and liquid level detection at the same time, reducing the running time; the code scanning device 100 uses software to collect real-time data and back-end parallel data processing, with high data processing efficiency, saving time and preventing human errors; the code scanning device 100 has strong compatibility and can be compatible with one-dimensional codes or two-dimensional codes of different formats and types to adapt to different application scenarios.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
