Leather Inspection Machine
1.Background and Needs
Artificial leather industry is difficult to solve the problem
China's artificial leather demand steadily upward, the domestic market into the steady growth, is expected to "fourteenfive" at the end, the domestic artificial leather demand will reach 5.5 billion squaremeters, the output value will exceed one hundred billion yuan. At present, the main domestic leather manufacturers, all relyon manualfactory before the finished product testing, b y manual testing efficiency, visual fatigue, subjective judgment of quality in stability and recruitment difficulties, skilled workers training high cost,the existing pure manual testing led to high leakage rate, finished leather detection rate is low, high labor costs, directly affect the production output, product grading and labor
costs.
(1)Difficult quality control
The following factors directly affect product grading:
High rate of missed detection by manual inspection
Black dots,white dots, blue dots and other defective points in red and orange fabrics are not easily identified by the naked eye.
(2)Detection efficiency
Manual inspection is governed by the following factors:
Manual inspection speed < 7m/min
Leather color:red and orange reflective,easily fatigued, difficult to identify, affecting detection efficiency.
Worker familiarity: detection efficiency is heavily dependent on worker proficiency.
(3)High cost and labor intensity
The following factors affect the cost of labor:
Shortage of skilled craftsmen
High turnover of personnel
High cost of training mature
mechanics (3-6 months).

3.Product introduction
First generation TR-001
1.Hardware Features
Product parameters
Fabric width ≤1600mm
Applicable fabric texture: applicable monochrome fine grain fabric;
Detection speed: ≤20m/min, 15m/min, 10m/min(rolled fabric speed adjusted according to actual needs of the site)
Flaw location indication area: 200mm*200mm Indicator light color: green LED light indication;
Minimum detection defect size: 0.2mm
Large defect detection rate 95% (spot, block defect, spot, stearic acid, spot, line (scratch, roll wrinkle, fine line, stripe)
Small defect detection rate 95% (hairy head,white spot, black spot, blue spot, stain, coke,insect stain, oil stain, color stripes, impurities,particles)
The system has batch number input function,batch number under the defect statistics function;Batch test result report output printing function.
2. Software Features
Automatic defect marking, conveyor start-stop control, detection of defects warning and other
functions, at the same time, you can query the detection of various basic information of the image,
touch operation instead of mouse operation, more humane.
3. Algorithm
Compared with the traditional machine learning algorithm, the deep learning algorithm we use is based on the YOLO series algorithm as the theoretical basis, and the target detection algorithm is self-developed and deeply optimized for the leather fabric inspection scene. Through the learning of massive leather fabric defect data, the SOTA model obtained has the characteristics of strong anti-interference, high detection rate, low false detection and leakage detection rate, and fast detection speed.
Second generation TR-002 (single-sided detection)/TR-003 (double-sided detection):
1.Hardware Features:
Product parameters
Fabric width :≤ 1600mm
Applicable fabric texture: applicable monochrome fine grain fabric.
Detection speed: ≤60m/min, 15m/min, 10m/min (rolled fabric speed adjusted according to the actual needs of the site)
Flaw location indication area: indication area range:200mm*200mm
