Description

Technical Field

[0001] This invention relates to the field of breeding technology, specifically to a seed cutting parent plant and sample correspondence collection coding system. Background Technology

[0002] In high-throughput gene analysis in molecular breeding, it is necessary to slice and sample a large number of seeds, ensuring that each sliced ​​sample accurately corresponds to its parent seed to guarantee the accuracy and traceability of subsequent gene data. Patent application CN202011616909.1 discloses a bio-breeding slicer, addressing the problems of existing slicing equipment having a fixed structure, inconveniently adjustable slice spacing, poor versatility, inability to fix the position of biological seeds during slicing, poor stability, and low slicing efficiency. The proposed solution includes a slicing stage with two connecting seats fixedly installed on its top. Each connecting seat has a movable hole on one side, and a single movable plate is slidably installed within each movable hole. Multiple adjustment slots are provided on the bottom of each movable plate, and adjustment plates are slidably installed within each of these slots. Blades are fixedly installed on the bottom of each adjustment plate. This slicer has a reasonable structure, is easy to operate, has a flexible structure, easily adjustable slice spacing, good versatility, and can meet different slicing needs. It can stabilize the position of biological seeds during slicing, resulting in good stability and high slicing efficiency.

[0003] Existing technologies primarily focus on addressing the physical operations of slicing itself, such as adjusting slice spacing and fixing seed positions to improve slicing efficiency and stability. However, such devices have a significant drawback: they lack the ability to automate and reliably manage the correspondence between sliced ​​samples and parent specimens.

[0004] Currently, the correspondence between samples and parent cultures relies heavily on manual labeling, dispensing, and recording. This method is inefficient in large-scale sample cutting scenarios and is prone to confusion. Once the correspondence between samples and parent cultures is lost or incorrect, the experimental data for the entire batch becomes worthless, resulting in a significant waste of time and resources. Therefore, there is an urgent need in this field for a coding and collection system that can be integrated into automated sample cutting equipment and can automatically and accurately establish and record the correspondence between samples and parent cultures. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention aims to provide a seed cutting parent and sample corresponding collection coding system. Based on the original laser equipment, by introducing coding control logic and position synchronization mechanism, it ensures that the sample cut from the same seed and the remaining parent are automatically and accurately collected into the collection box grid with a unique correspondence, and generates a traceable coding record, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a seed cutting parent and sample corresponding collection coding system, which is applied to a laser cutting device. The device includes a sample collection group for collecting samples and a body collection group for collecting parent plants. The sample collection group includes a first motion module and several sample boxes, and the body collection group includes a second motion module and several collection boxes.

[0007] The system includes a motion control system, a counter, and a cutting completion signal module; the motion control system is electrically connected to the first motion module and the second motion module.

[0008] The motion control system is configured to: control the first motion module to support the sample box and control the second motion module to support the first cell of the collection box to be located directly below the initial collection position; the value of the counter is set to N, with an initial value of 1; each time a drive command is generated according to the cutting completion signal, the value N of the counter is increased by 1; wherein, the current value N of the counter indicates the sequence number of the currently valid cell of the sample box and the collection box.

[0009] The cutting completion signal module generates a drive command after laser cutting, synchronously controlling the first motion module and the second motion module to move the collection positions of the sample box and the collection box to the next grid position. This enables the sample and the parent material produced by one cutting to be collected in the grid with the same serial number in the sample box and the collection box.

[0010] As a further improvement to this technical solution, the motion control system also includes a database for storing records; wherein the records include batch identifiers, grid numbers, and seed category information; each time the value N of the counter increases, a new record associated with the current grid number N is created.

[0011] As a further improvement to this technical solution, the motion control system also includes a seed discard signal module. If a seed discard signal is received, the response to the cutting completion signal module is suppressed, and no drive command is generated.

[0012] As a further improvement to this technical solution, the motion control system also includes a photoelectric sensor located on the sample falling path, used to detect whether a sample is falling, wherein the cutting completion signal module generates the drive command by the photoelectric sensor when it detects that a sample is falling.

[0013] As a further improvement to this technical solution, both the first motion module and the second motion module are XY two-axis motion modules, wherein the drive command is used to control the XY two-axis motion module to move a distance of one grid along the X-axis or Y-axis.

[0014] As a further improvement to this technical solution, the sample box and the collection box are multi-cell array boxes, with the cells arranged in a matrix; wherein the driving command is used to control the sample collection group to move all cells sequentially in a row-first or column-first order for collection.

[0015] As a further improvement to this technical solution, the first motion module and the second motion module have the same structure, both consisting of a servo motor and a lead screw connected coaxially, and a slider is threaded onto the lead screw; the top surface of the slider is disc-shaped and used to place several sample boxes and several collection boxes.

[0016] As a further improvement to this technical solution, a turntable is provided above the first motion module and the second motion module. Several pneumatic grippers are installed in a ring at equal intervals on the outer side of the turntable. The turntable rotates intermittently at a fixed angle by emitting pulses from a servo motor.

[0017] As a further improvement to this technical solution, the following steps are included:

[0018] S1. Initialize the first motion module and the second motion module so that the initial collection position is located at the first cell position of the sample box and the collection box, so as to be directly below the resting position of the pneumatic gripper;

[0019] S2. When the photoelectric sensor detects that the sample has fallen, it responds to the cutting completion signal module and synchronously drives the first motion module and the second motion module, so that the collection position of the sample box and the collection box moves synchronously to the next grid.

[0020] S3. Collect the sample and parent tissue generated from the first cut into the grids aligned with the sample box and collection box mentioned before the move.

[0021] As a further improvement to this technical solution, in step S2, the initial value of counter N is 1; after each synchronous drive, the value of N is increased by 1; wherein, in step S3, the sample and the parent are collected in the cell with serial number N, and after the drive, the collection position is aligned with the cell with serial number N+1.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This seed cutting and maternal parent corresponding collection coding system, through the setting of a synchronous motion control system and counter triggered by the cutting signal, completes the synchronous linkage drive and precise site coding of the sample box and maternal parent collection box, achieving the technical effect that after a successful cutting, the sample and maternal parent automatically fall into the same sequence number physical grid; and by integrating a database and dynamically associating it with the counter sequence number, it completes the automatic recording of batch, sequence number, variety and other information of each sample-maternal parent pair, achieving the technical effect of establishing a traceable electronic archive, providing an accurate data traceability foundation for subsequent gene analysis.

[0024] 2. This seed cutting parent and sample corresponding collection and coding system, by introducing discard signal identification and step suppression logic, completes the screening and filtering of invalid cutting events, achieving the technical effect of ensuring absolute consistency between the counter sequence number, physical grid position, and database record, greatly improving the reliability of the system and the accuracy of the data.

[0025] 3. The seed cutting parent plant and sample corresponding collection coding system automatically generates a cutting completion signal through photoelectric sensors, and automatically senses the successful drop of the sample. It achieves the technical effect of driving the system process with physical events, replacing manual intervention or program delay judgment, and further improves the automation level and response accuracy of the system.

However, the specific embodiments of the present invention described herein are for illustrative purposes only and should not be construed as limiting the invention in any way. Under the teachings of this invention, those skilled in the art will conceive of any possible variations of the invention, all of which should be considered within the scope of the invention. The terms "installation" and "connection" should be interpreted broadly, referring to direct connection as well as indirect connection through an intermediate medium.

[0036] The terms "central axis," "vertical," "horizontal," "front," "rear," "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer" used herein to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0037] Please see Figures 1-4 As shown, the present invention provides a seed cutting parent and sample corresponding collection coding system, which is applied to a laser cutting device. The device includes a sample collection group 200 for collecting samples and a body collection group 300 for collecting parent plants. The sample collection group 200 includes a first motion module 220 and a plurality of sample boxes 210, and the body collection group 300 includes a second motion module 320 and a plurality of collection boxes 310.

[0038] Specifically, the system includes a motion control system, a counter, and a cutting completion signal module; stored in a computer program, the motion control system is electrically connected to the first motion module 220 and the second motion module 320;

[0039] The motion control system is configured to: control the first motion module 220 to support the sample box 210 and control the second motion module 320 to support the collection box 310 so that the first cell position is directly below the initial collection position; the counter value is set to N, and its initial value is 1; after each time a drive command is generated according to the cutting completion signal, the counter value N is incremented by 1; wherein, the current value N of the counter indicates the sequence number of the currently valid cell of the sample box 210 and the collection box 310;

[0040] After laser cutting, the cutting completion signal module generates a drive command to synchronously control the first motion module 220 and the second motion module 320 to move synchronously to the next cell position of the sample box 210 and the collection box 310; thereby realizing that the sample and the parent material produced by one cutting are collected in the cells with the same number in the sample box 210 and the collection box 310.

[0041] Furthermore, the motion control system also includes a database for storing records; these records include batch identifiers, grid numbers, and seed type information; each time the counter value N increases, a new record is created associated with the current grid number N; the motion control system records associated information, such as batch identifiers, grid number N, seed type, cutting parameters, and timestamps, in a database;

[0042] Subsequently, researchers only need to record the batch identifier and grid number to find the corresponding parent and sample information from the database, or to find the paired sample and parent from the physical collection box by the grid number.

[0043] Furthermore, the motion control system also includes a seed rejection signal module. If a seed rejection signal is received, the response to the cutting completion signal module is suppressed, and no drive command is generated. During the preceding laser cutting of the seed, the vision system identifies the posture of the seed clamping and determines whether it can be cut. If the seed is judged to be unqualified and rejected at the posture recognition station or during the cutting process, the motion control system will recognize this "invalid cut" and will not trigger the stepping command of the box. This ensures that the counter N only counts successful and valid cutting events, guaranteeing absolute consistency between the physical grid and the data record.

[0044] Furthermore, the motion control system also includes photoelectric sensors located on the sample's falling path to detect whether a sample is falling. The drive command generated by the cutting completion signal module is produced by the photoelectric sensors when they detect that a sample is falling.

[0045] Furthermore, the sample box 210 and the collection box 310 are multi-cell array boxes, with their cells arranged in a matrix; the driving instructions are used to control the sample collection group 200 to move all cells sequentially for collection in a row-first or column-first order.

[0046] Furthermore, the first motion module 220 and the second motion module 320 have the same structure, both consisting of a servo motor and a lead screw connected coaxially, and a slider is threaded onto the lead screw; this is prior art and will not be described in detail here; the top surface of the slider is disc-shaped and is used to place several sample boxes 210 and several collection boxes 310.

[0047] Furthermore, both the first motion module 220 and the second motion module 320 are XY two-axis motion modules, wherein the drive command is used to control the XY two-axis motion module to move a distance of one grid along the X-axis or Y-axis; a turntable 100 is provided above the first motion module 220 and the second motion module 320, and several pneumatic grippers 110 are installed in a ring at equal intervals on the outer side of the turntable 100. The turntable 100 rotates intermittently at a fixed angle by emitting pulses from a servo motor. When the turntable 100 stops, the paused position of the pneumatic grippers 110 and located above the first motion module 220 and the second motion module 320 forms two collection positions for dropping seed samples and parent plants.

[0048] The seed cutting parent plant and sample correspondence collection and coding system of the present invention includes the following steps:

[0049] S1. Initialize the first motion module 220 and the second motion module 320 so that the initial collection position is located at the first cell position of the sample box 210 and the collection box 310, so as to be directly below the resting position of the pneumatic gripper 110.

[0050] After the system is started or the box is replaced, the motion control system controls the first motion module 220 and the second motion module 320 to reset, positioning the sample box 210 and the collection box 310 in the "1" grid position respectively; the motion control system generates a unique batch identifier and initializes a counter, N=1, which simultaneously points to the currently valid grid of the sample box 210 and the collection box 310.

[0051] S2. When the photoelectric sensor detects that a sample has fallen, it synchronously drives the first motion module 220 and the second motion module 320 in response to the cutting completion signal module, so that the collection positions of the sample box 210 and the collection box 310 move synchronously to the next grid; the initial value of the counter N is 1; after each synchronous drive, the value of N is increased by 1.

[0052] When a seed is laser-cut at the cutting station, two products are produced: the cut sample and the remaining parent plant. The pneumatic gripper 110 releases, and the sample falls due to gravity, about to fall into the sample box 210. The parent plant is then transported to the next station by the turntable 100, where the pneumatic gripper 110 releases, and the parent plant falls into the collection box 310. Thus, a successful cutting action triggers a stepping command for the box.

[0053] S3. Collect the sample and parent material generated from one cutting into the cells aligned with the sample box 210 and collection box 310 before the movement; the sample and parent material are collected in the cell with serial number N, and after the drive, the collection position is aligned with the cell with serial number N+1.

[0054] Whenever a parent sample is placed into the Nth cell of the collection box 310, the motion control system immediately and synchronously drives the first motion module 220 and the second motion module 320, causing the N+1th cell of the sample box 210 and the collection box 310 to move simultaneously to the collection position, which is directly below the pneumatic gripper 110 when it stops feeding. The counter N then increments by one. Therefore, the sample and parent sample produced by the Nth cut will necessarily be collected in the Nth cell of the sample box 210 and the collection box 310, respectively. The cell number N itself forms the most direct and reliable correspondence code.

[0055] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
