In this embodiment, optionally, the determining the inner shell attached with the target flat cable includes:
from the image of the target linehead, target image coordinates and center image coordinates of the target linehead are determined.
Determining a binary pixel equivalent value of a target image coordinate, and converting the target image coordinate into a target physical coordinate; determining a binary pixel equivalent value of a central image coordinate, and converting the central image coordinate into a central physical coordinate;
and according to the preset winding displacement position and the bonding deviation value of the target physical coordinate and the center physical coordinate, bonding the target winding displacement and the mobile phone inner shell to obtain the mobile phone inner shell bonded with the target winding displacement.
In this embodiment, an upper computer (e.g., a computer) needs to send a photographing instruction to a collection device (e.g., a CCD camera), and after the collection device receives the photographing instruction, a suction nozzle sucks a mobile phone screen to move to a collection device shooting cable position to perform image extraction of a target cable head; extracting the outline characteristics of the target winding displacement head to obtain the winding displacement center position, namely a target image coordinate (for example, the position coordinate of an elliptic point in fig. 3); recording the center position of the flat cable of the current image as a target point as a center image coordinate (for example, a position coordinate of a circular point in fig. 3); the coordinate diagram of the target linehead image is shown in FIG. 3; wherein, the target point is the central position of the wire arrangement of the current image; the object point is the center position of the moving flat cable.
The binary pixel equivalent value is a pixel equivalent value of a motion axis referenced when the object moves, specifically, the pixel equivalent value is an actual physical size represented by one pixel point in the image, and can be obtained by utilizing calibration logical operation extraction; for example, the binary pixel equivalent value in the present embodiment may be an XY pixel equivalent value. Specifically, the image coordinates are converted into the physical coordinates according to the binary pixel equivalent value, and the correlation correspondence between the converted physical coordinates and the image coordinates before conversion can be effectively ensured.
In this embodiment, before the lamination of the mobile phone inner shell hole and the flat cable is realized, a preset flat cable position can be pre-estimated by a professional according to experience, so that the lamination difference between the mobile phone inner shell hole and the flat cable can be effectively changed in the later stage according to the lamination deviation value of the target physical coordinate and the central physical coordinate, and the accurate lamination of the mobile phone inner shell hole and the flat cable can be realized.
And S120, determining the image coordinates of the inner shell of the mobile phone and the image coordinates of the screen of the mobile phone.
In the embodiment, a shooting instruction is simultaneously sent to two acquisition devices through an upper computer, and the two acquisition devices are instructed to respectively acquire the image coordinates of the inner shell of the mobile phone and the image coordinates of the screen of the mobile phone; the image coordinate of the mobile phone inner shell may be a vertex angle coordinate of the mobile phone inner shell, such as an upper left corner, a lower left corner, an upper right corner, or a lower right corner; the image coordinate of the mobile phone screen can be a vertex angle coordinate of a mobile phone screen surface of a joint surface with the mobile phone inner shell, such as an upper left corner, a lower left corner, an upper right corner or a lower right corner.

In this embodiment, to achieve effective attachment of the inner shell of the mobile phone and the screen of the mobile phone, it is necessary to ensure that the center point of the mobile phone and the center point of the screen of the mobile phone are on a vertical line, that is, the ratio of the image coordinate of the inner shell of the mobile phone to the image coordinate of the screen of the mobile phone should be the same with respect to the respective center points; for example, the image coordinates of the inner shell of the mobile phone and the image coordinates of the screen of the mobile phone can be correspondingly processed, and the deviation value of the screen of the inner shell of the mobile phone is gradually reduced according to the processed deviation value of the coordinates of the inner shell of the mobile phone and the screen of the mobile phone, so that the inner shell of the mobile phone and the screen of the mobile phone can be accurately attached.

Specifically, the physical coordinates are the numerical product between the pixel equivalent value and the image coordinates, such as: x (physical coordinates) = X pixel equivalent value X numerical value of image coordinate in X direction; y (physical coordinates) = Y pixel equivalent value x numerical value of image coordinate in the Y direction.
For example, the XY pixel equivalent value is calculated by using motion of passing 5 points during the alignment of the flat cables, and a display diagram of physical coordinates during the simulation of the XY axis motion is shown in fig. 5; wherein, the movement of the XY axes to the first point is assumed as the origin P 0 (0, 0) moving to a second point (upper right) P 1 (2, 2) moving to a third point (lower left) P 2 (-2, -2) moving to a fourth point (bottom right) P 3 (2, -2) moving to a fifth point (upper left) P 4 (-2, 2) from which various points and P can be derived 0 The XY distance between the spots was 2mm, from which it was found that:

Fig. 2 is a schematic flow chart illustrating a method for attaching a mobile phone inner case and a screen according to a second embodiment of the present invention. The embodiment is further expanded and optimized on the basis of the above embodiment, and can be combined with any optional options in the above technical solutions. As shown in fig. 2, the method includes:
s210, determining the mobile phone inner shell attached with the target flat cable.

In this embodiment, optionally, the image coordinates of the mobile phone inner shell include a first image coordinate and a second image coordinate; the image coordinates of the mobile phone screen comprise a third image coordinate and a fourth image coordinate. Specifically, the image coordinates of the mobile phone inner shell may be left upper point coordinates and right lower point coordinates of the mobile phone inner shell, or left lower point coordinates and right upper point coordinates; the image coordinates of the mobile phone screen can be left upper point coordinates and right lower point coordinates or left lower point coordinates and right upper point coordinates of the mobile phone screen attached to one surface of the mobile phone inner shell. In the embodiment, the coordinates of the vertex position are selected as the image coordinates, so that the structural characteristics of the inner shell of the mobile phone or the screen of the mobile phone can be completely expressed through the image coordinates.
S230, determining the ternary pixel equivalent values of the first image coordinate and the second image coordinate, and determining the ternary pixel equivalent values of the third image coordinate and the fourth image coordinate.
In this embodiment, in order to implement complete attachment of the mobile phone screen of the mobile phone inner case, it is necessary to determine the ternary pixel equivalent value of the image coordinate of the mobile phone inner case and the ternary pixel equivalent value of the mobile phone screen; specifically, the three-element pixel equivalent value is the pixel equivalent value of three motion axes referred to when the object moves, and specifically, the pixel equivalent value is the actual physical size represented by one pixel point in the image and can be obtained by utilizing calibration logical operation extraction; for example, the ternary pixel equivalent value in the present embodiment may be a XYA pixel equivalent value; wherein, the A pixel equivalent value is an angle pixel equivalent value; is obtained by R axis rotation.
S240, converting the first image coordinate into a first physical coordinate, and converting the third image coordinate into a third physical coordinate; and converting the second image coordinate into a second physical coordinate, and converting the fourth image coordinate into a fourth physical coordinate.
In this embodiment, after the coordinates of each preset vertex image are determined, the pixel equivalent value of each preset vertex image is combined, and the pixel equivalent value corresponding to the coordinate value of each direction point is multiplied by the coordinate value of each direction point to obtain the physical coordinates corresponding to the image coordinates, so that the automatic laminating equipment can accurately and efficiently complete the laminating process according to the physical coordinates.
And S250, attaching the mobile phone inner shell and the mobile phone screen according to the attachment deviation value of the first physical coordinate and the third physical coordinate, the attachment deviation value of the second physical coordinate and the fourth physical coordinate and the preset attachment screen position.
In this embodiment, a vertex coordinate is taken as an image coordinate for example, an upper left point coordinate and a lower right point coordinate of a mobile phone inner shell are defined as a first image coordinate and a second image coordinate, and an upper left point coordinate and a lower right point coordinate of a mobile phone screen are defined as a third image coordinate and a fourth image coordinate. Specifically, a schematic diagram showing image coordinate points of the inner shell and the screen of the mobile phone is shown in fig. 6, and it can be seen that an upper left point coordinate of an outer dotted line rectangle in fig. 6 is a first physical coordinate; the coordinate of the lower right point of the outer dotted line rectangle is a second physical coordinate; the coordinate of the upper left point of the inner dotted rectangle is a third physical coordinate; and the coordinate of the lower right point of the inner dotted rectangle is a fourth physical coordinate. And then, the mobile phone screen is attached to the mobile phone inner shell by combining the preset attaching screen position, so that the complexity of the mobile phone inner shell and the mobile phone screen in the attaching process is effectively simplified.
On the basis of the foregoing embodiment, optionally, determining the ternary pixel equivalent value of the first image coordinate and the second image coordinate includes:

In the present embodiment, the determination of the binary pixel equivalent value is the same as the principle of determining the binary pixel equivalent value in the first embodiment, and therefore, the detailed description is omitted in the present embodiment.
For example, the pixel equivalent value calculation of the inner shell of the mobile phone and the screen of the mobile phone selects 8-point motion calculation, and the display diagram of the image coordinate during the simulated motion is shown in fig. 7, and based on the 5-point calibration in the first embodiment, 3-point calibration is performed; assuming that the XY axes move to the fifth point as the origin P 5 (0, 0), the R axis rotates clockwise by 2 degrees to obtain a sixth point P 6 And the R shaft rotates anticlockwise by 2 degrees to obtain a seventh point P 7 . When the position of the intersection point in the corresponding image changes when the R axis moves, then:
wherein, in the formula (2), I 6 The rotation angle from the fifth point to the sixth point; I.C. A 7 The rotation angles from the fifth point to the seventh point; x is a radical of a fluorine atom 5 、x 6 And x 7 The abscissa of the fifth point, the sixth point and the seventh point respectively; y is 5 、y 6 And y 7 The ordinate of the fifth point, the sixth point and the seventh point, respectively.
From equation (2), the angular pixel equivalent value is as follows:
on the basis of the foregoing embodiment, optionally, determining the ternary pixel equivalent value of the third image coordinate and the fourth image coordinate includes:
determining a binary pixel equivalent value for the second image coordinate; and determining a binary pixel equivalent value for the fourth image coordinate;

In this embodiment, the principle of determining the three-element pixel equivalent values of the third image coordinate and the fourth image coordinate is the same as the principle of determining the three-element pixel equivalent values of the first image coordinate and the second image coordinate, that is, the X pixel equivalent value and the Y pixel equivalent value are obtained by 5-point motion, then the angular pixel equivalent value is obtained by 3-point rotation motion, and finally the XYA pixel equivalent value is obtained.
