Display screens are an indispensable component of modern electronic products, and are widely used in various industries. Glue injection is one of the essential key steps in the display screen production process. The traditional glue injection method generally uses a single channel, which may have certain limitations on some complex display screen structures and cannot meet the requirements. Therefore, the embodiment of the application provides a multichannel glue injection control method and device for display screen production, so as to solve the problems.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flow chart of a multi-channel glue injection control method for display screen production according to an embodiment of the present application, and as shown in fig. 1, the multi-channel glue injection control method for display screen production according to an embodiment of the present application includes steps S100 to S600.
Step S100, acquiring image information and function information of a component to be injected, determining a region to be injected based on the image information of the component to be injected, and determining a target glue solution injected into the region to be injected based on the function information; the component to be injected is a component on the display screen to be injected.
The image information of the to-be-injected component can be acquired through the image capturing device, and to different to-be-injected components, to-be-injected areas are different, for example, when the to-be-injected component is a display panel, the whole to-be-injected component is usually required to be injected, when the to-be-injected component is a backlight module, the whole backlight module is not required to be injected, and the specific injection range of the backlight module depends on the design and the requirement of the display screen.
It will be appreciated that the type of the target glue solution depends on the function of the component to be injected, for example, when the component to be injected is a display panel, the display panel is mainly used for displaying images or characters, so the target glue solution is optical glue, and when the component to be injected is a driving circuit, the driving circuit is easy to generate heat during operation, so the target glue is heat-conducting glue.
Step 200, obtaining information of an image of the region to be injected, and dividing the region to be injected into a plurality of sub regions to be injected based on the information of the image of the region to be injected.
And step S300, matching the glue injection channels for each sub-region to be injected respectively.
And step S400, extracting features of each sub-region to be injected with glue to obtain sub-region features of each sub-region to be injected with glue, and acquiring performance parameter information of the target glue solution.
Step S500, determining a glue injection control parameter set based on all the sub-region characteristics and the performance parameter information; the glue injection control parameter set comprises glue injection control parameters of each glue injection channel.
And S600, controlling a glue solution input device to input the target glue solution into each glue injection channel, and controlling each glue injection channel to execute glue injection operation on the glue injection area based on the glue injection control parameter set.
According to the method, firstly, the to-be-injected area is divided into a plurality of to-be-injected subareas, the to-be-injected subareas are matched with the injection channels, the injection control parameter sets are determined based on the subarea characteristics of the to-be-injected subareas and the performance parameter information of the target glue solution, then the glue solution input device is controlled to input the target glue solution into each injection channel, and the glue injection operation is performed on the to-be-injected area by controlling each injection channel based on the glue injection control parameter sets.
In some embodiments, the features of the sub-region to be injected include region profile features of the sub-region to be injected, and the method for extracting the region profile features of the sub-region to be injected includes:
acquiring an image of the sub-region to be injected, and preprocessing the image of the sub-region to be injected to obtain a preprocessed image;
detecting the edge of the sub-region to be injected with the Canny edge detection algorithm on the preprocessed image to obtain the edge information of the sub-region to be injected with the glue;
acquiring information of edge defects of the sub-region to be injected based on the edge information, and repairing the edge defects based on a preset edge repairing method to obtain standard edges of the sub-region to be injected;
performing contour extraction on the standard edge by utilizing a findContours function in OpenCV to obtain region contour information of the sub-region to be injected;
and analyzing the region contour information based on a preset graphic contour analysis model to obtain the region contour characteristics of the to-be-injected sub-region.
The method of the embodiment can more accurately detect the edge of the sub-region to be injected, repair the possible defects of the edge of the sub-region to be injected, and is beneficial to improving the accuracy of the region outline characteristics of the sub-region to be injected, so that the injection effect of the sub-region to be injected is improved.
In some embodiments, the dividing the region to be injected into a plurality of sub-regions to be injected based on the information of the image of the region to be injected includes:
acquiring a training graph, wherein the training graph is segmented into a plurality of sub-graphs;
extracting the edge contour of the training graph;
inputting the edge contour of the training graph into an initial region segmentation model to obtain a comparison graph of the training graph;
extracting a first graphic feature and a second graphic feature based on a preset graphic feature extraction model, and calculating the similarity between the first graphic feature and the second graphic feature; the first graphic feature is the graphic feature of the training graphic, and the second graphic feature is the graphic feature of the comparison graphic;
comparing the similarity with a preset similarity;
if the similarity is smaller than the preset similarity, analyzing error information between the training pattern and the comparison pattern based on a preset error analysis model;
adjusting model parameters of the initial region segmentation model based on the error information to obtain an intermediate region segmentation model;
iterating the steps until the similarity is not smaller than the preset similarity to the middle region segmentation model to obtain a target region segmentation model;
dividing the region to be injected into a plurality of sub regions to be injected based on the target region division model.
The multiple sub-graphics are obtained by manually dividing the region in the edge contour of the training graphics based on the features of the edge contour of the training graphics, and if the region to be injected is divided by adopting the dividing mode of the training graphics, the glue injection effect of the region to be injected can be improved (for example, the target glue solution is more uniformly distributed in the region to be injected, so that cracks and bubbles generated after the glue solution is solidified are reduced), and the quality of the display screen is improved.
It should be noted that, the above steps are iterated on the middle region segmentation model until the similarity is not less than the preset similarity, the middle region segmentation model may be iterated by acquiring a new training pattern again, or the middle region segmentation model may be iterated by using the original training pattern.
After the method of the embodiment is adopted to divide the to-be-injected area, the subsequent effect of injecting the to-be-injected area can be improved, and therefore the quality of the display screen is improved.
In some embodiments, the number of the glue injection channels is not smaller than the number of the sub-areas to be injected, and the matching glue injection channels for each sub-area to be injected respectively includes:
respectively acquiring the position of each sub-region to be injected and the placement position of each injection channel;
acquiring a first position relation based on the position of each sub-region to be injected, and acquiring a second position relation based on the placement position of each injection channel; the first positional relationship is a positional relationship between positions of the sub-areas to be injected, and the second positional relationship is a positional relationship between placement positions of the injection channels;
and matching a glue injection channel for each sub-area to be injected based on the first position relation and the second position relation.
By adopting the method of the embodiment, each glue injection sub-area can be matched with a glue injection channel which is matched with the position relation of the glue injection sub-area, so that when each glue injection channel moves to the glue injection sub-area which is matched with the glue injection sub-area, the moving paths of the glue injection channels are not mutually interfered, the glue injection efficiency is improved, and the production efficiency of the display screen is further improved.
In some embodiments, the sub-region features include a capacity of the sub-region to be injected and structural information of the sub-region to be injected, the performance parameter information includes an optimal bonding temperature of the target glue solution, and determining the glue injection control parameter set based on all the sub-region features and the performance parameter information includes:
obtaining optimal glue injection time set for the to-be-injected component;
determining the glue injection speed of the glue injection channel based on the optimal glue injection time and the capacity of the sub-areas to be injected for each sub-area to be injected, and determining the glue injection pressure of the glue injection channel based on the glue injection speed;
determining the position of an injection channel matched with the sub-region to be injected according to the structural information of the sub-region to be injected for each sub-region to be injected when the sub-region to be injected is injected;
and determining the glue injection temperature of the glue injection channel based on the optimal bonding temperature for each sub-area to be injected with glue.
It can be appreciated that, the shorter glue injection time may cause that the target glue solution is unevenly distributed in the to-be-injected area, so as to affect the display effect of the display screen, and on the other hand, the shorter glue injection time may also cause that the to-be-injected component cannot be fixed, and the longer glue injection time may increase the manufacturing cost of the display screen, so that it is required to set an optimal glue injection time for the to-be-injected component.
By adopting the scheme in this embodiment, individualized glue injection control parameters can be set for each glue injection subarea, the glue injection speed of the glue injection channel is determined based on the optimal glue injection time and the capacity of the glue injection subarea for each glue injection subarea, and the glue injection pressure of the glue injection channel is determined based on the glue injection speed, so that a proper amount of target glue solution can be injected into each glue injection subarea, waste of the target glue solution is avoided, meanwhile, the target glue solution can be uniformly distributed in each glue injection subarea, and the stability of the glue injection assembly can be improved by determining the optimal bonding temperature as the glue injection temperature of the glue injection channel.
In some embodiments, before the acquiring the image information and the functional information of the component to be injected, the method further includes:
acquiring component installation relation image information of the display screen to be injected, and determining a plurality of components to be injected of the display screen to be injected based on the component installation relation image information;
determining a third positional relationship based on the component mounting relationship image information; the third position relationship is a position relationship among a plurality of to-be-injected assemblies;
and determining the glue injection sequence of each to-be-injected assembly based on the third position relation.
It can be understood that, for the display screen with the same assembly installation relationship, when the glue injection sequences of all the to-be-injected assemblies are different, the performance of the display screen may be greatly affected, and by adopting the method of the embodiment, a reasonable glue injection sequence is automatically given to all the to-be-injected assemblies of the display screen, so that on one hand, the glue injection effect of injecting glue to the display screen is improved, the quality of the display screen is improved, and on the other hand, the glue injection efficiency of injecting glue to the display screen is also improved.
In some embodiments, the determining a third positional relationship based on the component mounting relationship image information includes:
