Fig. 1 shows according to the present invention for manufacturing the schematic diagram of the device 100 of blade.
As shown in Figure 1, device 100 include laser 101, the laser 101 its be configured as multiple laser beams 105
The laying position on production tooling bracket 104 is projected to form multiple laser labellings 106, wherein 106 structure of the laser labelling
At multiple laying positions 107.It should be noted here that the present invention may be used also although the present embodiment is illustrated by taking laser as an example
To use the visible light beam of other visible lights, such as collimatedization.
Device 100 further includes production tooling bracket 104, and the production tooling bracket 104 is configured as what bearing to be manufactured
Blade 104.
Device 100 further includes camera 102, and the camera 102 is configured as the image of shooting blade 104.
In addition, device 100 further includes controller (not shown), the controller is configured as:
According to the laying information for the laying material for wanting laying, for example the start-stop position put, laying width, laying thickness with
And material type etc. and tolerance determine laying position；
Laser beam 105 is projected to fabrication region to indicate the laying position by indication laser 101；
The image of the laying material (such as glass-fiber-fabric) of the institute's laying obtained by camera 102 is analyzed to determine paving
Error is put, wherein the analysis can be completed by image recognition, mode is for example are as follows: institute's laying is identified in described image
Each laying material boundary, and the boundary and laying position (containing tolerance) are compared, wherein being more than threshold in difference
Providing when value indicates to spread inclined signal；It is identified in described image by identifying color and/or the size of the material of institute's laying
The information of each laying material of institute's laying, and corresponding alarm is issued in the case where Cuo Pu, leakage paving, more pavings；In order to realize
The identification, can in advance to associated disadvantages type carry out machine learning, then by system by way of pattern-recognition come reality
When identify various defects；After corresponding defect is identified, system will generate the examining report of defect and its grade, and in correspondence
Region generates examining report after completing maintenance again；To not by regulation complete maintenance region can also be identified again,
And provide warning message；These examining reports will become the important component of blade archives, obtain whole life cycle forever
Kubo is deposited, and system can also find to carry out damage information and production defect and maintenance position certainly when damage during operation

The behavior of producers is monitored to find unlawful practice, such as producers whether in workplace something lost
Stay foreign matter, producers whether dress protective garment or shoe cover and the whether excessive glue spraying of producers, producers it is whether long when
Between chat or do not work etc., the identification can for example be carried out by pattern-recognition.
The operational process of brief description the solution of the present invention.
Firstly, multiple laser beams 105 are projected to blade system according to the laying position determined by controller by laser 101
It makes to form multiple laser labellings 106 in region, wherein the laser labelling 106 prompts multiple laying regions 107.
Then, by producers or by automated system will laying material placement corresponding with laser labelling 106 to phase
It answers in laying region 107.
Later, the image of blade 104 is shot by camera 102, wherein determining laying error, such as by image recognition
Cuo Pu, more pavings, leakage paving and paving are inclined.
Finally, providing corresponding alarm according to laying error.
Fig. 2 shows the top views for the blade 104 to be manufactured.It should be pointed out that described overlook the difference for showing blade
Laying region, the laying region are only exemplary, and can be different because of blade construction design difference.
As shown in Fig. 2, being projected on blade 104 for laser beam generates multiple laser labellings 106, and the laser labelling
106 determine multiple laying region 201-205 again.
The laser labelling can have different colours to prompt the laying material of laying difference size or material, Huo Zhesuo
Laser labelling is stated other than laser lines also with other symbols, such as character come prompting laying difference size or different materials
Laying material.
It should be noted here that although illustrate only the camera 102 of vertical direction in the present embodiment, other
It, can be with the camera in pitch-based sphere direction so that identification layer is high or is laid with the number of plies in embodiment.
As shown in Fig. 2, producers or automated system can be according to the laser labellings come laying difference size or difference
The laying material of material.When pawnshop putting material deviates from scheduled laying position or situations such as Cuo Pu, more pavings, leakage paving occurs
When, device 100 can provide corresponding alarm.
The present invention at least have it is following the utility model has the advantages that the present invention also provides the identification of laying error and prompting function, by
This enables producers or automated system to correct error in time, to improve the accuracy of manufacture.
