[0002] Industrial spectral analysis technology has wide applications in fields such as the detection of components in traditional Chinese medicine, fruit quality grading, and identification of crop diseases and pests. However, traditional spectral acquisition equipment has the following problems: 1. Manually operated detection system Samples need to be placed manually and positioned point by point, and a single test takes 3-5 minutes, which affects production efficiency. In addition, operators need to have professional spectral knowledge.

[0003] 2. Fixed spectral probe equipment The probe position is not adjustable, and it is only suitable for standard-sized samples (such as a box of fruit), and cannot be used for small-sized targets (such as rice grains or Chinese medicine powder); it is highly sensitive to vibration, and the vibration of the workshop environment causes large spectral drift errors.

[0004] 3. Basic Automated Mobile Platform The use of single-axis guide rails or low-precision stepper motors for driving results in insufficient positioning accuracy, requiring repeated positioning, and the low focusing efficiency of the spectral camera cannot meet the cycle time requirements of the production line.

[0018] Two inspection ports 101 are provided on the workbench 100. The two inspection ports 101 are arranged in parallel to each other.

At the same time, the inspected inspection port 101 is fed into the new workpiece, realizing seamless alternation operation.

[0019] The drive assembly 300 includes a guide rail 301, a slider 302, a fixed plate 303, a servo motor 304, a drive pulley 305, a driven pulley 306, an internal gear belt 307, a fixed bearing 308, a rotating shaft 309, a gear 310, and a rack 311.

[0022] The implementation principle of a fully automatic gantry-structure industrial spectral acquisition device according to an embodiment of this application is as follows: Step 1: Device Initialization Start system self-test: three-axis zero positioning, autofocus module calibrates reference focal length (response < 0.5s).

[0023] Step 2: Workpiece positioning and path planning An external conveyor sends the fruit box into the detection port 101, and the photoelectric sensor triggers a boundary scan. The system generates a 1000mm×1000mm grid path (point spacing is adjustable, minimum 10mm×10mm).

[0024] Step 3: Triaxial Coordinated Motion and Data Acquisition X-axis and Y-axis positioning: The first servo slide rail module 500 drives the crossbeam 200 to move along the Y-axis to the target column; The drive assembly 300 drives the drive pulley 305 to rotate via the servo motor 304. The drive pulley 305, the driven pulley 306, and the internal toothed belt 307 work together to drive the rotating shaft 309 to rotate. The rotating shaft 309 drives the gear 310 to rotate. The gear 310 and the rack 311 work together to push the crossbeam 200 to move along the X-axis to the target row.

[0025] Z-axis focusing and acquisition: The second servo slide rail module 600 descends at a speed of 5 mm / s to the high frame rate hyperspectral camera 400. The through-beam photoelectric sensor triggers the high-frame-rate hyperspectral camera 400 to acquire data at the optimal focal length position; Two high-frame-rate hyperspectral cameras 400 work simultaneously: the upper high-frame-rate hyperspectral camera 400 collects fruit surface color and texture, while the lower high-frame-rate hyperspectral camera 400 detects fruit pulp density.

[0026] Step 4: Continuous Operation and Switching After one detection port 101 is completed, the crossbeam 200 automatically moves to another detection port 101 to perform the same process; After the inspection port 101 is completed, a new workpiece is simultaneously fed in, realizing seamless alternating operation (using the 200 span of the crossbeam to cover the two workstations).

[0027] Step 5: Data Feedback and Adjustment The system transmits spectral data to the analysis terminal in real time. If an abnormal area (such as mold spots) is found, the system automatically densifies the grid points in that area (50mm×50mm→10mm×10mm) for re-inspection.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
