step S2: processing the image to determine the positions of the first marker 21 and the second marker 22;
step S3: determining a machining position according to the positions of the first mark 21 and the second mark 22, wherein the machining position is used for machining the body 1.
In particular, the processing method provided by this embodiment can be applied to the processing of the accessory, the first surface 101 of the accessory includes the identification set, the set of marks comprises at least a first mark 21 and a second mark 22, an image of the first surface 101 of the body 1 of the accessory is first acquired, the image comprises a first mark 21 and a second mark 22, the image is processed, the positions of at least the first mark 21 and the second mark 22 can be determined after the processing, the processing position can be determined according to the positions of the first mark 21 and the second mark 22, the machining position is used for machining the first surface 101 of the body 1, and the first surface 101 of the body 1 may have at least one machining position, and when the first surface 101 has two or more machining positions, all machining positions on the first surface 101 can be determined simultaneously according to the positions of the first mark 21 and the second mark 22; in the following, taking the processing as an example of disposing an adhesive material at the processing position of the first surface 101 of the body 1, i.e. dispensing, the accessory is first fixed at a predetermined position, for example: the accessory can be fixed on the carrier, the accessory is driven to move to the position right below the visual field center of the CCD camera, or the CCD camera is driven to move, the visual field center of the CCD camera is enabled to be positioned right above the first surface 101 of the accessory, and the image of the first surface 101 of the body 1 is acquired by shooting through the CCD camera; after the image is acquired, the positions of the first mark 21 and the second mark 22 meeting the standard need to be found on the image, and the processing position is determined according to the positions of the first mark 21 and the second mark 22, so that the accurate dispensing of the processing position of the first surface 101 of the body 1 is realized.
Further, in a specific implementation, the determining the machining position according to the positions of the first mark 21 and the second mark 22 includes: and comparing deviation values of the positions of the first mark 21 and the second mark 22 with the position of the reference mark 3, and adjusting and determining the machining position according to the deviation values.
Specifically, before processing, a reference image of a reference part needs to be acquired, and positions of two reference marks 3 corresponding to a first mark 21 and a second mark 22 are determined on the reference image, it should be noted that the reference image is a reference determined as a processing position, and the reference marks 3 and the reference dispensing path 4 have a binding relationship, so that the reference part and the part to be processed belong to the same material, and the shape and the size of the reference part need to be kept the same, and in addition, the positions of the two reference marks 3 on the reference image, which correspond to the positions of the reference part, are the same as the positions of the first mark 21 and the second mark 22 of the acquired image on the part to be processed; comparing the deviation value between the first mark 21 and the second mark 22 and the two reference marks 3 on the reference part, that is, comparing the deviation value between the positions of the part to be processed and the same position on the reference part, because the deviation value exists between the positions of the first mark 21 and the second mark 22 and the two reference marks 3, that is, it is described that the position where the part to be processed is placed is not completely consistent with the position where the reference part is placed, and when the position where the part to be processed is not consistent with the position where the reference part is placed, if the part to be processed is processed according to the processing position corresponding to the reference part, the problem of inaccuracy such as deviation of the processing position occurs, therefore, in this step, after obtaining the deviation value between the positions of the first mark 21 and the second mark 22 and the two reference marks 3, the processing position can be compensated by using the deviation value, and then the processing position after compensation is performed, accurate processing can be realized.
Then, the adhesive material is disposed on the first surface 101 of the main body 1 at the processing position, that is, for example, the dispensing method may first calculate a first relative coordinate of the first identifier 21 with respect to the CCD camera according to a relative position between the first identifier 21 and a center of a field of view of the CCD camera, then calculate a second relative coordinate of the second identifier 22 with respect to the CCD camera in the same way, and then convert the first relative coordinate and the second relative coordinate into a mechanism coordinate in a coordinate system with respect to the movement mechanism according to a conversion relationship between the coordinate system of the CCD camera and the coordinate system of the movement mechanism, further obtaining the coordinates of the first mark 21 point and the second mark 22 point, calculating the coordinates of the two reference marks 3 based on the same mode, and comparing the coordinates of the first mark 21 point and the second mark 22 point with the coordinates of the two reference marks 3 to obtain a deviation value of the position; after the deviation value is obtained, the deviation value is used for compensating the dispensing path of the automatic dispenser, and then the dispensing path after compensation is used for dispensing the to-be-processed accessories, so that accurate dispensing on the to-be-processed accessories can be realized, the dispensing of the to-be-processed accessories can be accurate and reliable, and the product yield and the processing efficiency can be improved.
