Description

TECHNICAL FIELD

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

[0002] In the quality detection production line of domestic chemical industry, pharmaceutical intermediates, polymer materials and other industries, sample processing is a key pre-link. These industries need to manage hundreds of samples produced daily in detail, which need to be classified according to the detection task type (such as component content detection, temperature resistance detection, heavy metal residue detection), and then temporarily stored in the corresponding environment (such as normal temperature storage area, low temperature refrigeration area, explosion-proof storage area). After the detection is completed, the samples need to be sorted according to the detection results (qualified, to be rechecked, unqualified) to ensure that qualified samples flow into the next production link and unqualified samples are disposed according to the rules. The whole process runs through the whole process of quality detection, directly affecting the detection efficiency and production progress.

[0003] At present, the sample processing link in this field in China relies on manual intervention technology mode as a whole. The specific process is as follows: the operator first receives the samples transmitted by the production end, checks the information (such as sample number, detection task code) on the sample label manually, and puts the samples into the corresponding classification basket; then, the operator pushes the temporary storage cart and puts the classified samples one by one on the shelves in the designated temporary storage area, and records the sample temporary storage position by paper record or simple electronic form; when the detection equipment completes the detection and outputs the report, the operator manually finds the corresponding sample in the temporary storage area according to the report result, and sorts it into the qualified product turnover box, the to-be-rechecked product special basket or the unqualified product processing barrel. The core classification, temporary storage positioning and sorting actions are not involved in the whole process, and the core operations are completed by manual work.

[0004] The existing manual intervention technology mode has the following significant shortcomings: first, the cost is high, and the enterprise needs to recruit a large number of operators to be responsible for sample processing, and needs to invest in special training cost. Because the handling specifications of different samples (such as corrosive chemical samples, flammable and explosive samples) are different, the operators need to undergo systematic training to master the safety requirements of classification and temporary storage, resulting in a continuous increase in the proportion of labor cost and training cost in production cost; second, the efficiency is low, the time-consuming of manual label checking, manual sample handling and paper record positioning is long, especially during the sample peak period (such as after batch production), which is easy to cause sample backlog, resulting in prolonged waiting time in the detection link and slowing down the overall production cycle; third, the error rate is high, the operator is easy to make mistakes such as label misreading, classification misplacement and temporary storage position recording deviation after a long time of work, which not only may cause the mismatch between detection results and samples, but also may cause safety hazards due to the mixing of flammable and explosive samples and corrosive samples, threatening the stability and safety of the production line.

[0021] In specific use of the sample sorting device 100 according to the embodiment of the application, first, the sample bottles are placed into the sample bottle collecting area 110 of the sample feeding conveyor belt platform 11 by manual operation, and the sample bottle collecting area 110 can be arranged to meet the collection of at least 80 sample bottles in a single batch. The sample bottles are conveyed by the conveyor belt of the sample feeding conveyor belt platform 11 to the release mechanism 2, the guide channel 20 only allowing a single sample bottle to pass through on the release mechanism 2 changes the sample bottles from a disordered state to a single column moving back to enable the sample bottles to pass through the first code scanning mechanism 3 in turn, the sample bottles are scanned and identified one by one by the first code scanning mechanism 3, and the channeling mechanism 5 places different sample bottles into the corresponding sample separation area in the lane 4 according to the code scanning rules, wherein the abnormal sample bottles that do not pass the code scanning identification enter the abnormal area for subsequent manual processing.

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.

[0023] 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.

[0024] 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.

[0025] With the above-described configuration, the material release mechanism 2 according to the embodiment of the present invention has the following advantages: 1) the V-shaped structure design has better guiding and collecting effects, so that the sample bottles can be concentratedly moved toward the guiding channel 20; 2) the asymmetric arrangement, that is, the guiding wall surfaces of the channel portions 201 are arranged in staggered front and back (as shown in Figure 5 Fig. 2), so that the sample bottles are not directly aligned with the inlet of the guiding channel 20 in the moving process, but are received by the wall surfaces of the low guiding portions 202 when approaching the inlet of the guiding channel 20, so that the sample bottles are partially guided into the guiding channel 20, and then combined with the wall surfaces of the channel portions 201 on the other side, so as to gradually guide the sample bottles into the channel portions 201, thereby avoiding the sample bottles from being stuck at the inlet of the guiding channel 20; 3) if the sample bottles are stuck, the first bottle pushing assembly 23 can also push the bottles at a certain frequency to further prevent the risk of the sample bottles being stuck.

[0026] Please refer to Figure 7 In some embodiments, the first bottle pushing assembly 23 can include a cylinder seat 231 fixed to the fume hood rack body 1, a cylinder 232 fixed to the cylinder seat 231, and a pushing block 233 fixed to the telescopic end of the cylinder 232, which pushes the sample bottles into the guiding channel 20 by being telescoped with the cylinder 232.

[0027] In this embodiment, the cylinder 232 can be arranged to be telescoped at a certain frequency. In this embodiment, the first bottle pushing assembly 23 can be arranged at the back side of the left side blocking strip 21 or the right side blocking strip 22, and in the embodiment as shown in Figure 5 , the first bottle pushing assembly 23 is arranged at the back side of the left side blocking strip 21, and the left side blocking strip 21 is formed with a channel for the pushing block 233 to pass through.

[0029] In this embodiment, the pushing part 234 can be configured as a plate-shaped structure or an arc-shaped structure. The shielding part 235 arranged can shield the gap formed between the pushing part 234 and the wall surface of the blocking strip in the moving process of the pushing part 234, so as to avoid the problem that the sample bottles are stuck in the gap due to the too large gap.

At the same time, the detection switch 35 arranged can synchronously detect the presence or absence of the sample bottles. The sample bottles classified by the code are classified by the channel mechanism 5 according to the code information, and different sample bottles are put into the corresponding lanes 4, and the abnormal sample bottles not recognized by the code are put into the abnormal area, and the personnel are notified to handle after the storage is full.
