Description

Technical Field

[0001] Embodiments of the present invention relate to the field of laboratory sample processing equipment. More specifically, the present invention relates to a sample sorting device. Background Technology

[0002] In the quality testing production lines of domestic chemical, pharmaceutical intermediates, and polymer materials industries, sample processing is a crucial preliminary step. These industries need to manage hundreds or even thousands of samples generated daily with meticulous care. Samples must first be categorized according to the type of testing task (e.g., component content testing, temperature resistance testing, heavy metal residue testing), and then temporarily stored in corresponding environments (e.g., ambient temperature storage area, low-temperature refrigeration area, explosion-proof storage area). After testing, samples must be sorted according to the results (qualified, awaiting retesting, unqualified) to ensure that qualified samples flow into the next production stage and unqualified samples are disposed of according to regulations. This entire process permeates the entire quality testing workflow and directly impacts testing efficiency and production progress.

[0003] Currently, the sample processing stage in this field in China relies entirely on manual intervention. The specific process is as follows: operators first receive samples from the production end, manually verify the information on the sample labels (such as sample number and testing task code), and manually classify the samples into the corresponding classification bins. Subsequently, operators push temporary storage carts to place the classified samples one by one on the shelves in the designated temporary storage area, and record the temporary storage location of the samples using paper records or simple electronic spreadsheets. After the testing equipment completes the testing and outputs a report, operators then manually locate the corresponding samples in the temporary storage area based on the report results, and sort them into qualified product turnover boxes, special bins for products awaiting re-inspection, or non-conforming product disposal bins. Throughout the entire process, no automated equipment is involved in the core classification, temporary storage positioning, and sorting actions; all core operations are completed manually.

[0004] Existing manual intervention techniques have significant drawbacks: First, they are costly, requiring companies to hire a large number of operators to handle samples and invest in specialized training. Different samples (such as corrosive chemicals and flammable / explosive samples) have different handling requirements, necessitating systematic training for operators to master the safety requirements for classification and temporary storage. This leads to a continuous increase in labor and training costs as a percentage of production costs. Second, they are inefficient, with manual label verification, sample handling, and paper record positioning being time-consuming, especially during peak sample volumes (such as after batch production). This can cause sample backlog, extending waiting times in the testing process and slowing down the overall production cycle. Third, they have a high error rate, as operators are prone to fatigue after long hours of work, leading to misreading labels, incorrect classification, and inaccurate temporary storage records. This can not only result in mismatched test results but also pose safety hazards due to the mixing of flammable / explosive and corrosive samples, threatening the stability and safety of the production line. Summary of the Invention

This invention serves as a bridge between personnel and automated testing systems.

[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0030] The sample sorting device 100 in this embodiment of the invention serves as a link between personnel and the automated testing system. Quality inspectors place sample bottles onto the sample sorting device 100, which automatically scans the QR codes on each bottle, automatically determines the validity and category of the sample, and automatically performs temporary storage in designated areas. Based on the scheduling information from the laboratory management system, the sample bottles are loaded onto AGV desktop carts and delivered to the automated testing system.

[0031] Figures 1 to 3 The structure of a sample sorting device 100 according to an embodiment of the present invention is shown. Figure 4 A schematic diagram of the sample sorting device 100, including the sample inlet conveyor platform 11, the release mechanism 2, and the lane 4, is shown. Figures 1 to 4As shown, the sample sorting device 100 includes: a fume hood frame 1, in which a sample inlet conveyor platform 11 is horizontally arranged, the sample inlet conveyor platform 11 being used to transport sample bottles from a sample bottle collection area 110 to a waiting area 111; and a release mechanism 2, disposed on the fume hood frame 1 and above the sample inlet conveyor platform 11, disposed in the sample bottle collection area 110 of the sample inlet conveyor platform 11, the release mechanism 2 having a guide channel 20 for only a single sample bottle to pass through and a first barcode scanning mechanism 3 disposed at the outlet of the guide channel 20, the release mechanism 2 being used to sort disordered sample bottles into a single row, and to identify and classify the sample bottle QR codes through the first barcode scanning mechanism 3; and a lane 4. The sample collection mechanism 4 is located in the sample collection area 111 of the sample conveyor platform 11. The lane 4 includes a sample separation area and an abnormal area. The output position of the lane 4 is equipped with a second scanning mechanism 40, which is used to re-identify the sample bottles in the corresponding lane 4. The separation mechanism 5 is located between the release mechanism 2 and the lane 4. The separation mechanism 5 is equipped with a bottle gripping component 51, which is used to grab the sample bottles that have been scanned and identified by the scanning mechanism 3 of the release mechanism 2 and place them into the corresponding sample separation area or abnormal area according to their category. The bottle collection mechanism 6 is located at the output position of the lane 4. The bottle collection mechanism 6 is equipped with a gripper component 60, which is used to grab the sample bottles in the collection area 111 to the external AGV desktop trolley 200.

[0032] In practical use, the sample sorting device 100 according to an embodiment of the present invention first involves manually placing sample bottles into the sample bottle collection area 110 of the sample conveyor platform 11. The sample bottle collection area 110 can be configured to collect at least 80 sample bottles per batch. The sample bottles are conveyed backward by the conveyor belt of the sample conveyor platform 11 and enter the release mechanism 2. The guide channel 20 on the release mechanism 2, which allows only one sample bottle to pass through at a time, transforms the sample bottles from a disordered state into a queue that moves backward, so that the sample bottles can pass through the first scanning mechanism 3 in sequence. The sample bottles are scanned and identified one by one by the first scanning mechanism 3. The sorting mechanism 5 places different sample bottles into the sorting area in the corresponding lane 4 according to the scanning rules. Sample bottles that fail to pass the scanning identification are abnormal and enter the abnormal area for subsequent manual processing. As the sample vials enter the sample distribution area of ​​lane 4, they continue to move backward with the sample delivery conveyor belt. At the baffles set within lane 4, the sample vials are sorted from multiple columns into a single column. After being identified by the second barcode scanning mechanism 40, they wait in the pick-up area for the bottle-picking mechanism 6 to pick them up. The bottle-picking mechanism 6 loads the sample vials onto the AGV desktop cart 200 and delivers them to the automated detection system.

[0033] With the above-described configuration, the sample sorting device 100 according to this embodiment of the invention can automatically complete the collection, classification, temporary storage, and sorting of sample bottles (and the samples within them), and transport them to various automated testing processes via the AGV desktop cart 200. This saves a significant portion of labor costs compared to conventional manual operation, achieving efficient and reliable sample sorting, thereby improving production efficiency while avoiding potential operational errors and safety hazards associated with manual operation.

[0034] Please refer to Figure 5 and Figure 6 In some embodiments, the release mechanism 2 may include: a left baffle 21 and a right baffle 22, both fixed to the fume hood frame 1. Both the left baffle 21 and the right baffle 22 include a guide portion 202 and a channel portion 201. The distance between the guide portions 202 gradually decreases along the conveying direction, and the channel portions 201 are arranged in parallel to form a guide channel 20. A first bottle-pushing assembly 23 is disposed on the guide portion 202 near the guide channel 20, and is used to push the sample bottle. The guide portions 202 of the left baffle 21 and the right baffle 22 are asymmetrically arranged, and the channel portions 201 are staggered, one in front of the other. The first bottle-pushing assembly 23 is disposed on the guide portion 202 connected to the rear channel portion 201.

[0035] In this embodiment, the release mechanism 2 is constructed as an asymmetrical, approximately V-shaped structure (e.g., Figure 5 (As shown). Staff place the sample bottles within the sample bottle collection area 110, i.e., within the V-shaped structure. As the conveyor belt transports the samples, they gradually converge at the entrance of the guide channel 20. At this point, there is a risk of the sample bottles getting stuck. In this embodiment, the left-side baffle 21 and the right-side baffle 22 are arranged in a staggered, one in front of the other (as shown). Figure 5 (As shown by the dashed line). It can be as follows: Figure 5 As shown, along the direction of movement of the conveyor belt, the wall of the guide channel 20 portion of the left baffle 21 is located on the rear side. In this embodiment, a first bottle pusher assembly 23 (which may be positioned near the guide channel 20) is provided. Figure 5 A first bottle-pushing assembly 23 is provided on the left-side baffle 21 shown. The first bottle-pushing assembly 23 can push the sample bottles at a set frequency. The first bottle-pushing assembly 23 can push the sample bottles away to prevent them from getting stuck at the entrance of the guide channel 20. After passing through the release mechanism 2, the sample bottles change from a disordered state to a line and move backward.

[0036] With the above-described configuration, the material release mechanism 2 according to the embodiment of the present invention has the following advantages:

[0037] 1) The V-shaped structure design provides better guiding and collection effects, allowing sample bottles to move in a concentrated manner towards the guide channel 20; 2) The asymmetrical arrangement, i.e., the guide walls of the channel section 201 are staggered (e.g., ...). Figure 5 As shown), during the movement of multiple sample bottles, they are not directly aligned with the entrance of the guide channel 20. Instead, when they approach the entrance of the guide channel 20, the sample bottles are received by the wall of the lower guide section 202, allowing the sample bottles to partially enter the guide channel 20. Then, they combine with the wall of the channel section 201 on the other side, gradually guiding the sample bottles into the channel section 201, so as to avoid the sample bottles getting stuck at the entrance of the guide channel 20. 3) If the sample bottles get stuck, the first bottle pushing component 23 can also push the bottles at a certain frequency to further prevent the risk of the sample bottles getting stuck.

[0038] Please refer to Figure 7 In some embodiments, the first bottle pushing assembly 23 may include: a cylinder seat 231 fixed to the fume hood frame 1; a cylinder 232 fixed to the cylinder seat 231; and a push block 233 fixed to the telescopic end of the cylinder 232, the push block 233 extending and retracting with the cylinder 232 to push the sample bottle into the guide channel 20.

[0039] In this embodiment, the cylinder 232 can be configured to extend and retract at a certain frequency. In this embodiment, the first bottle-pushing assembly 23 can be located behind the left side stop 21 or the right side stop 22, as shown in the example. Figure 5 In the embodiment shown, the first bottle pusher assembly 23 is disposed on the rear side of the left side baffle 21, and a channel for the pusher block 233 to pass through is formed on the left side baffle 21.

[0040] Please continue to refer to Figure 6 and Figure 7 In some embodiments, the push block 233 may include: a pushing part 234, which is fixed to the driving end of the cylinder 232, the pushing part 234 is arranged parallel to the guide surface of the guide part 202, and the moving direction is perpendicular to the guide part 202; and a blocking part 235, which is connected to the side of the pushing part 234 away from the guide channel 20, the blocking part 235 extends along the direction of the cylinder 232 and perpendicular to the pushing part 234, and the extension length of the blocking part 235 is greater than or equal to the moving distance of the pushing part 234.

[0041] In this embodiment, the pushing part 234 can be constructed as a plate-shaped structure or an arc-shaped structure. The shielding part 235 is provided to shield the gap formed between the pushing part 234 and the wall of the baffle during movement, thereby preventing the sample bottle from getting stuck in the gap due to excessive size.

[0042] Please refer to Figures 8 to 10In some embodiments, the first scanning mechanism 3 may include: a main drive mechanism 31 on which a drive wheel 311 is disposed; a driven mechanism 32 opposite to and spaced apart from the main drive mechanism 31, a driven wheel 321 disposed on the driven mechanism 32, and a pressing channel 33 connected to the outlet of the guide channel 20 is formed between the driven mechanism 32 and the main drive mechanism 31; a barcode scanner 34 disposed on the driven mechanism 32; and a detection switch 35 disposed on the driven mechanism 32 and located above the barcode scanner 34.

[0043] In this invention, by setting up a first scanning mechanism 3, sample bottles pass through the pressing channel 33 one by one with the cooperation of the active wheel 311 and the passive wheel 321. During the process of passing through the pressing channel 33, the barcode scanner 34 scans the sample bottles to obtain sample bottle information. At the same time, the detection switch 35 can simultaneously detect the presence or absence of sample bottles. After scanning and sorting, the sample bottles are classified by the sorting mechanism 5 according to the scanning information, and different sample bottles are placed into the corresponding swimming lanes 4. Those that fail to pass the scanning identification are abnormal sample bottles and enter the abnormal area. When the area is full, personnel are notified for processing.

[0044] Please continue to refer to Figures 8 to 10 In some embodiments, the drive mechanism 32 may include: a clamping mechanism bracket 322, which is fixed to the fume hood frame 1, and the detection switch 35 and the barcode scanner 34 are both fixed to the clamping mechanism bracket 322; and two sets of clamping components 323, which are fixed to the clamping mechanism bracket 322 at intervals. Each set of clamping components 323 includes: a slide cylinder 324, which is fixed to the clamping mechanism bracket 322; a passive wheel support 325, which is fixed to the drive end of the slide cylinder 324; and a passive wheel 321, which is set on the passive wheel support 325 by a pin. A clamping channel 33 is formed between the two passive wheels 321 and the drive wheel 311. The two passive wheels 321 are arranged opposite to the drive wheel 311 and located on both sides of the drive wheel 311, capable of clamping the sample bottle and driving the sample bottle to rotate.

[0045] Please continue to refer to Figures 8 to 10 In some embodiments, the main drive mechanism 31 may include: a drive motor bracket 312 fixed to the fume hood frame 1; a drive motor 313 fixed to the drive motor bracket 312; and a drive wheel 311 disposed on the shaft of the drive motor 313. The rotation axes of the two driven wheels 321 and the drive wheel 311 are arranged vertically and parallel to each other.

[0046] Please return Figure 4In some embodiments, the lane 4 may include a sub-lane consisting of a plurality of parallel and spaced partitions 41, the partitions 41 being fixed to the fume hood frame 1. The sub-lane includes: two adjacent partitions 41; a curved plate 42, which is fixed to the fume hood frame 1, the curved plate 42 including a bent section 421 and a straight section 422, the bent section 421 and the partition 41 on one side forming a tapered opening that allows only a single sample bottle to pass through, the straight section 422 being arranged parallel to the partition 41; a connecting plate 43, which is disposed at the end of the sub-lane, the two ends of the connecting plate 43 being fixedly connected to the partition 41 and the straight section 422; and a partition 44, which is detachably disposed on the straight section 422 and the partition 41, so as to divide the sub-lane into two regions.

[0047] In this embodiment, there can be six sub-lanes, of which four sub-lanes correspond to the subsequent direct chromatographic separation module and the chromatographic separation pretreatment module, one sub-lane corresponds to the subsequent physicochemical detection, namely moisture detection, titration detection, density detection, and pH detection, and one sub-lane can be the finished sample, which is scheduled with the highest priority. In this embodiment, the connecting plate 43 is fixedly connected to the end of the partition plate 41 and the straight plate section 422 so that the end of the sub-lane forms a blind lane.

[0048] Specifically, the sample bottles entering the sub-lane move backward with the conveyor belt, and at the tapering end, the sample bottles gradually change from multiple columns to a single column. Afterward, each sample bottle is scanned by the second scanning mechanism 40 and then waits in the waiting area 111 for the bottle-picking mechanism 6 to pick it up. In this embodiment, a partition 44 divides the waiting area within the sub-lane into two waiting areas 111, each operated by two sets of bottle-picking mechanisms 6 simultaneously. Furthermore, if one set of bottle-picking mechanisms 6 malfunctions, the partition 44 can be removed, allowing the other set of bottle-picking mechanisms 6 to pick up the bottles uniformly in the same waiting area 111. Once picked up, the sample bottles are placed into the AGV desktop cart 200.

[0049] Please continue to refer to Figure 4 and Figure 11 In some embodiments, the sub-lane may further include a second bottle-pushing assembly 45, which is disposed at the tapered end of the sub-lane.

[0050] In this embodiment, a second bottle-pushing component 45 can be provided to prevent the sample bottle in the sub-lane from getting stuck.

[0051] Please return Figure 4In some embodiments, the lane 4 may also include a side plate 46, which is fixed to the fume hood frame 1 and arranged parallel to one side of the outer partition of the sub-lane. An abnormal area sub-lane is formed between the side plate 46 and the adjacent partition, allowing only a single sample bottle to pass through.

The gripper has a V-groove, and the detection switch is used to detect whether a sample bottle has been gripped.

[0054] In some embodiments, two sets of bottle-picking mechanisms 6 may be symmetrically arranged, each including an X-axis module, a Y-axis module, a Z-axis module, and a pneumatic gripper. The X-axis module is fixed to the upright of the fume hood frame 1. The Y-axis module is fixed to the X-axis module slider via a connector. The Z-axis module slider is fixed to the Y-axis module slider. The pneumatic gripper is fixed to the bottom of the Z-axis module.

The camera positioning system may include a positioning camera, a light source, a light source holder, and a support rod. The light source holder and support rod one are fixed to the fume hood frame 1. The light source consists of four light source strips forming a quadrilateral and is fixed to the light source holder. Support rod two can move up and down along support rod one. The positioning camera is fixed to support rod two via a camera connector, which can move back and forth along support rod two to adjust the shooting position.
