Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an embodiment of a dynamic dispensing compensation method according to an embodiment of the present invention, and for convenience of description, only a portion related to the embodiment of the present invention is shown. Specifically, the dynamic dispensing compensation method specifically includes:
s101, obtaining a target image of a target material.
Specifically, in the dispensing process, a target material is fixed at a predetermined position, for example, the target material is fixed on a carrier, and the target material is driven to move to a position below the center of the visual field of the visual camera, or the visual camera is driven to move, so that the center of the visual field of the visual camera is located above the target material, and the target material is photographed by the visual camera to obtain a target image of the target material.
And S102, determining a first Mark point on the target image.
That is, after the target image is obtained, at least one feature point needs to be found on the target image, and the feature point is used as a first Mark point, specifically, the visual camera may perform processing analysis according to the target image to find a feature point that meets requirements, for example, positions such as an edge and a corner of the target image have obvious features, and these positions may be used as the feature point.
S103, calculating a deviation value between a first Mark point on the target image and a second Mark point on the template image, wherein the template image is an image obtained by shooting a template material, the shape and the size of the template material are the same as those of the target material, the first Mark point is a feature point on the target material, and the second Mark point is a feature point on the template material corresponding to the same position on the target material.
Specifically, before dispensing, a template image of the template material needs to be acquired, and a second Mark point needs to be determined on the template image. It should be noted that the template image is used as a reference datum for path compensation, and therefore, the template material and the target material belong to the same material class, and the shape and the size of the template material need to be kept the same. In addition, the position of the second Mark point on the template image corresponding to the template material is the same as the position of the first Mark point on the target image corresponding to the target material, for example, the first Mark point corresponds to a corner position on the template material, and the second Mark point also corresponds to the same corner position on the target material.
Calculating a deviation value between a first Mark point on the target image and a second Mark point on the template image, namely calculating a deviation between the target material and the same position on the template material. Preferably, the relative coordinates of the first Mark point with respect to the visual camera may be calculated according to the relative position between the first Mark point and the center of the field of view of the camera. And then converting the relative coordinate into a mechanism coordinate under the coordinate system of the relative motion mechanism according to the conversion relation between the coordinate system of the vision camera and the coordinate system of the motion mechanism, thereby obtaining the coordinate of the first Mark point. In the same manner, the second Mark point coordinates of the second Mark point may be calculated. And finally, comparing the coordinates of the first Mark point with the coordinates of the second Mark point to obtain a deviation value between the first Mark point and the second Mark point.
It should be noted that, in the application of the visual camera, the visual camera needs to be calibrated by using a calibration algorithm, for example, the visual camera needs to be calibrated by using a nine-point calibration algorithm, that is, an operator moves into nine points distributed in three horizontal directions, three vertical directions at fixed intervals, and takes pictures nine times respectively, and then, according to the acquired mechanism coordinates of the nine points, the conversion relationship between the coordinate system of the visual camera and the coordinate system of the motion mechanism, the coordinates can be converted based on the conversion relationship.
And S104, compensating the dispensing path of the target material according to the deviation value.
Because a deviation value exists between the first Mark point on the target image and the second Mark point on the template image, it is described that the placing position of the target material is not completely consistent with the placing position of the template material, and when the placing position of the target material is not consistent with the placing position of the template material, if the target material is subjected to glue dispensing according to the glue dispensing path corresponding to the template material, the glue dispensing path on the target material obviously has inaccurate problems of deviation and the like.
According to the dynamic dispensing compensation method provided by the embodiment of the invention, the target image of the target material is obtained, the first Mark point is determined on the target image, the deviation value between the first Mark point on the target image and the second Mark point on the template image is calculated, and the dispensing path of the target material is compensated according to the deviation value, so that the dispensing path of the target material is ensured to be accurate and reliable, an operator does not need to deliberately place a fixed position of the material when feeding the material, even if the angle difference exists, the axe can be obtained through the compensation and the deviation rectification of the dispensing path, the dispensing effect is more stable, and the quality and the yield can be obviously improved.
It should be noted that, in the present application, a standard dispensing path of the same type of material is established in advance before dispensing processing, so that when dispensing is performed on subsequent materials of the same type, compensation is performed based on the standard dispensing path, and thus, accuracy of dispensing is ensured.
Illustratively, the steps of establishing the standard dispensing path are as follows:
and acquiring a template image of the template material.
And determining a second Mark point on the template image.
And recording a dispensing path of the dispensing equipment during dispensing of the template material, and taking the dispensing path as a standard dispensing path.
Specifically, the carriers may be reloaded with a template material that is too small in size and shape to be subsequently dispensed, as described above, before being prepared for production processing, to ensure that the template material is horizontal. And then, acquiring a template image of the template material by using a visual camera, and determining a second Mark point on the template image. And then, the dispenser can be manually debugged, the dispenser is controlled to dispense on the template material by a preset dispensing path, the preset dispensing path is matched with the template material, and a dispensing needle head of the dispenser is stored to move to each coordinate point on the preset dispensing path to serve as a standard dispensing path.
Correspondingly, the step S104 of compensating the dispensing path of the target material according to the deviation value includes:
and acquiring a standard dispensing path of the template material.
And compensating the standard dispensing path according to the deviation value to form an actual dispensing path matched with the target material, wherein the actual dispensing path is used for controlling the dispensing equipment to dispense the target material.
That is to say, after a deviation value between a first Mark point of the target image and a second Mark point on the template image is obtained, the standard dispensing path can be compensated according to the deviation value to obtain an actual dispensing path of the target material, and the dispenser is controlled to dispense the target material according to the actual dispensing path.
Referring to fig. 2 to 3, in one embodiment of the present invention, the first Mark point and the second Mark point are both two; the step S103 includes:
s201, calculating an included angle between a first straight line and a second straight line support, wherein the first straight line is a connecting line between two first Mark points, and the second straight line is a connecting line between two second Mark points.
S202, calculating deviation values of the middle point of the first straight line and the middle point of the second straight line in the X direction and the Y direction.
Correspondingly, the compensating the standard dispensing path according to the deviation value to form an actual dispensing path matched with the target material includes:
s301, performing angle compensation on the standard dispensing path according to the included angle to form a first compensation path, wherein the first compensation path is parallel to the target material.
S302, according to the deviation values in the X direction and the Y direction, the first compensation path is subjected to translation compensation in the X direction and the Y direction to form a second compensation path, and the second compensation path is used as the actual dispensing path.
Specifically, a connecting line between two first Mark points is a first straight line, a connecting line between two second Mark points is a second straight line, and when there is a deviation between the position where the target material is placed and the position of the template material, an included angle may exist between the first straight line and the second straight line, and certainly, the included angle may also be parallel, so that the included angle between the first straight line and the second straight line is calculated first. After the included angle between the first straight line and the second straight line is obtained, the obtained first compensation path and the target material can form a parallel state only by correcting the angle of the standard dispensing path of the template material by the included angle. And comparing the coordinates of the middle point of the first straight line and the center of the second straight line, calculating deviation values of the first straight line and the second straight line in the X direction and the Y direction, respectively compensating the first compensation path in the X direction and the Y direction according to the deviation values in the X direction and the Y direction to obtain a second compensation path, and enabling the second compensation path to be overlapped with the target material to serve as an actual dispensing path of the target material.
In this embodiment, by adopting the above manner, the included angle between the target material and the template material and the deviation values in the upper X direction and the upper Y direction are calculated, and then the compensation is performed respectively according to the included angle and the deviation values, so that the actual dispensing path formed after the compensation can be ensured to be matched with the target material, and further the dispensing is accurate, reliable and stable, and the product yield and efficiency are higher.
In one embodiment of the invention, determining the first Mark point on the target image comprises:
and detecting each corner feature point on the target image.
And taking two detected corner characteristic points of the diagonal line on the target image as first Mark points.
The determining a second Mark point on the template image comprises:
and detecting each corner feature point on the template image.
And taking two detected corner feature points of the diagonal line on the template image as second Mark points.
In this embodiment, the corner characteristic points of two opposite angles on the target material are used as the first Mark points, and the corner characteristic points of two opposite angles on the template material are used as the second Mark points, so that the first straight line formed by connecting the two first Mark points is the diagonal line of the target material, the first straight line formed by connecting the two second Mark points is the diagonal line of the template material, and the included angle between the two diagonal lines is calculated, so that the included angle that can be calculated can accurately reflect the angle difference between the target material and the template material. The center point of the first straight line is the center of the target material, and the center of the second straight line is the center of the template material, so that the deviation values of the centers of the first straight line and the second straight line in the X direction and the Y direction can accurately reflect the deviation of the target material and the template material in the X direction and the Y direction, and further, the matching degree between the actual dispensing path and the target material obtained according to the included angle and the deviation value compensation is higher, and dispensing is more accurate.
