As shown in fig. 2, which is a schematic flowchart of an embodiment of a precise superspeed position correction method in an embodiment of the present application, the precise superspeed position correction method may include:
21. a first distance between the display panel and the laser device is acquired.
The accurate superspeed position correction method provided by the embodiment of the application is applied to a panel detection device. As shown in fig. 3, a schematic structural diagram of an embodiment of a display panel detection apparatus provided in the present application is shown; in fig. 3, the display panel detection apparatus may include: superspeed ultrasonic motor, laser device, picture acquisition device, microscope carrier and bearing structure. And the ultra-high speed ultrasonic motor can control the picture acquisition device to move up and down in the vertical direction. The laser device may emit laser light to the display panel and receive the laser light displayed by the display panel to determine a distance between the display panel and the laser device by a time of the laser light back and forth between the two. The image acquisition device may be a camera or the like.
Therefore, in the embodiment of the present application, a first distance between the current laser device and the display panel may be obtained by using the laser device; to determine the area where the warpage occurs in the display panel according to the first distance, and therefore the position correction of the picture taking device is required.
In the embodiments of the present application, the distance between the laser device and the stage is kept constant, that is, the distance between the laser device and the display panel is theoretically kept constant. However, the distance between the laser device and the display panel is changed due to the warping of the display panel, so that the position of the picture acquisition device can be adjusted, and the distance between the picture acquisition device and the display panel is kept unchanged.
22. A first mapping relation between a preset voltage of the ultra-high-speed ultrasonic motor and a first distance is obtained.
Because the display panel has a warping problem, the distance between the whole display panel and the laser device is not completely the same, and in order to ensure that the pictures of the display panel collected by the picture acquisition device are collected at the same height, the position of the picture acquisition device needs to be adjusted. Specifically, the distance between the image capture device and the display panel is adjusted in the vertical direction.
In the present application, the ultra-high speed ultrasonic motor is used to control the movement of the image capturing device, and therefore, the voltage of the ultra-high speed ultrasonic motor is specifically adjusted to adjust the position of the ultra-high speed ultrasonic motor, and further adjust the distance between the image capturing device and the display panel.
A certain mapping relation exists between the voltage of the ultra-high-speed ultrasonic motor and the first distance, so that the voltage of the ultra-high-speed ultrasonic motor can be adjusted according to the first distance; and the adjusted voltage of the ultra-high speed ultrasonic motor is used for controlling the moving distance of the picture acquisition device in the vertical direction.
23. And determining a target voltage corresponding to the ultra-high-speed ultrasonic motor according to the first mapping relation and the first distance.
24. And correcting the position of the picture acquisition device according to the target voltage.
Specifically, the target voltage corresponding to the ultra-high-speed ultrasonic motor may be directly determined according to the first mapping relationship and the first distance, and the ultra-high-speed ultrasonic motor may be controlled to operate at the target voltage to adjust the position of the image capturing device.
The precise superspeed position correction method provided by the embodiment of the application comprises the following steps: acquiring a first distance between a display panel and a laser device; acquiring a mapping relation between the voltage of a preset ultra-high-speed ultrasonic motor and the first distance; determining a target voltage corresponding to the picture acquisition device according to the mapping relation and the first distance; and correcting the position of the picture acquisition device according to the target voltage. According to the method and the device, the laser signals are converted into the voltage signals, the time required by data processing is shortened, meanwhile, the position of the picture acquisition device is rapidly adjusted by the aid of the high-speed and ultrahigh-speed ultrasonic motor with low inertia response speed, the detection speed of the display panel detection device is greatly increased, and pictures acquired by the picture acquisition device are all at the same height.
In the above embodiment, if the position of the image capturing device is to be adjusted according to the distance, the first distance between the area to be detected on the current display panel and the laser device and the first mapping relationship between the voltage of the ultra-high speed ultrasonic motor and the first distance are depended on. As shown in fig. 4, a flowchart of an embodiment of determining a first mapping relationship between an ultra-high speed ultrasonic motor and a first distance provided by the embodiment of the present application may include:
41. and acquiring a standard distance between the display panel and the laser device.
42. And acquiring a second distance between the display panel and the laser device.
43. A distance difference between the standard distance and the second distance is calculated.
Specifically, in the embodiment of the present application, the position of the image capturing device needs to be adjusted continuously, and then whether the adjusted position is accurate is determined; and continuously adjusting the position of the picture acquisition device according to the adjusted result. Therefore, the standard distance between the display panel and the laser device needs to be acquired first; the standard distance is a distance between a display panel non-warped area and the laser device.
And meanwhile, acquiring a second distance between the current display panel and the laser device, and subtracting the second distance by using the standard distance to obtain a distance difference value between the current display panel and the laser device. If the distance difference is greater than 0, it indicates that the currently detected area of the display panel is warped, and therefore the position of the image capturing device needs to be adjusted.
44. And acquiring an initial proportional parameter between a preset distance difference value and the voltage of the ultra-high-speed ultrasonic motor.
45. And adjusting the position of the picture acquisition device according to the initial proportion parameter and the distance difference value.
When the position of the image acquisition device is adjusted, an initial proportion parameter between a preset distance difference value and the voltage of the ultra-high speed ultrasonic motor can be acquired first, so that the image is adjusted according to the initial proportion parameter and the distance difference value. The method specifically comprises the following steps:
acquiring a second mapping relation between the voltage of a preset ultra-high-speed ultrasonic motor and the moving distance of the ultra-high-speed ultrasonic motor; acquiring the actual moving distance of the picture acquisition device according to the second mapping relation and the initial proportion parameter; judging whether the actual distance is equal to the distance difference value or not; if the actual distance is not equal to the distance difference, adjusting the initial proportion parameter, and acquiring the actual moving distance of the device from the adjusted picture by using the adjusted proportion parameter.
In the embodiment of the present application, there is actually a certain mapping relationship, i.e., a second mapping relationship, between the voltage of the ultra-high speed ultrasonic motor and the moving distance corresponding to the ultra-high speed ultrasonic motor; and the second mapping relationship corresponding to different ultra-high speed ultrasonic motors may be different. The second mapping relationship can be simply understood that the voltage of the ultra-high speed ultrasonic motor is increased to a certain extent, and the rotating speed of the ultra-high speed ultrasonic motor can be greatly increased, so that the ultra-high speed ultrasonic motor is driven to move for a certain distance. However, in the embodiment of the present application, due to the difference in the warping degree of the display panel, the distance of each movement of the ultra-high speed ultrasonic motor is different. Therefore, the embodiment of the application provides a proportion parameter, and the moving distance of the ultra-high speed ultrasonic motor is adjusted by using the proportion parameter.
Specifically, since the distance to be moved (i.e., the distance difference) is determined, there is a proportional parameter, which is used to adjust the voltage of the ultra-high speed ultrasonic motor. In the embodiment of the present application, the process of determining the first mapping relationship is actually a process of determining a specific value of the ratio parameter.
Therefore, an initial proportion parameter can be defined, and the voltage of the ultra-high speed ultrasonic motor is adjusted by using the initial proportion parameter and the second mapping relation, so that the actual moving distance of the picture acquisition device is adjusted. If the actual distance of the movement of the picture acquisition device is different from the distance difference value; the distance between the moved image acquisition device and the display panel still does not reach the standard distance, and the position of the image acquisition device still needs to be adjusted.
Therefore, the initial scale parameter can be adjusted, and the actual moving distance of the picture acquisition device can be readjusted by using the adjusted scale parameter. Generally speaking, at this time, before the actual distance moved by the picture acquisition device is determined again by using the adjusted ratio parameter, the picture acquisition device needs to be moved to the initial distance; rather than at a position after the initial movement.
In the above embodiment, the initial ratio parameter needs to be adjusted continuously until the actual distance of the image acquisition device is adjusted and acquired by using the adjusted target ratio parameter, which is equal to the distance difference; at this time, a first mapping relation between the voltage of the ultra-high speed ultrasonic motor and the first distance can be determined according to the target proportion parameter.
Specifically, when the position of the picture taking device is actually adjusted, the distance that the picture taking device moves is actually a distance difference, and the distance difference is usually not very large. Therefore, in the embodiment of the application, the ultra-high-speed ultrasonic motor with small inertia and high response speed is selected to control the movement of the picture acquisition device, so that the picture acquisition device can be moved quickly even if a warping area is encountered when the display panel is detected, and the acquired pictures of the display panel are all at the same height.
And the initial proportion parameter is used for adjusting, in fact, the voltage of the ultra-high speed ultrasonic motor is adjusted by using the initial proportion parameter. The first mapping relation between the voltage of the ultra-high-speed ultrasonic motor and the first distance is actually the mapping relation between the voltage of the ultra-high-speed ultrasonic motor and the distance difference between the current distance between the display panel and the laser device and the standard distance; namely the mapping relation between the ultra-high speed ultrasonic motor and the distance difference. The distance difference is actually the distance that the image acquisition device needs to move, and a second mapping relationship also exists between the voltage of the ultra-high-speed ultrasonic motor and the moving distance (namely the distance difference) of the ultra-high-speed ultrasonic motor; therefore, after the adjusted target proportion parameter is determined, the mapping relation between the voltage of the ultra-high-speed ultrasonic motor and the distance difference value can be determined according to the adjusted target proportion parameter and the second mapping relation, namely the first mapping relation between the voltage of the ultra-high-speed ultrasonic motor and the first distance is determined.
As shown in fig. 5, a control flow chart of the precise ultra-high speed position correction method provided in the embodiment of the present application is shown. In fig. 5, a picture taking device, such as a camera, is fixed in a fixed position on the support structure, and the laser device may emit a light signal to the display panel on the stage, and the display panel may reflect the light signal to the laser device, thereby determining the current distance between the laser device and the display panel.
Meanwhile, an optical signal fed back by the display panel is sent to the photoelectric conversion control system to be converted into an electric signal, and the electric signal is sent to the ultra-high-speed ultrasonic motor to control the ultra-high-speed ultrasonic motor to drive the picture acquisition device to move, so that the distance between the moved picture acquisition device and the display panel reaches a standard distance.
In the embodiment of the present application, a photoelectric conversion control system is provided, so that the flow of a complete correction picture acquiring apparatus is from the original: the method comprises the following steps of emitting and collecting reflected laser by a laser device, obtaining height data according to the reflected laser, refreshing and scanning the height data by an upper computer, analyzing and comparing the data by the upper computer degree, and controlling a motor-motor response to carry out position adjustment by an output signal of the upper computer; the conversion is: the laser device emits and collects reflected laser, a photoelectric conversion control system and a super-high speed ultrasonic motor to carry out position adjustment. The method avoids multiple processing of signals, improves the signal processing time, and greatly shortens the position adjustment period of the picture acquisition device. And the speed of adjusting the position of the picture acquisition device is greatly improved by using the ultra-high-speed ultrasonic motor with small inertia and high response speed.
