Problems solved by technology
During the operation, due to the existence of errors in the contact dispensing process, when the needle is replaced periodically, repeated dispensing calibration may cause a certain deviation in the calibration of the dispensing needle in the XY direction, and the consistency of high-precision dispensing cannot be achieved. ; At the same time, in the traditional method of needle calibration in XY direction, the step of dispensing needs to be repeated, which is inefficient and cannot meet the needs of high-efficiency dispensing

The invention discloses a single CCD based dispensing needle head correcting method and device. The single CCD based dispensing needle head correcting method comprises the following steps that firstly, a CCD collects the initial XY coordinate value of a preset dispensing needle head; secondly, the CCD collects the real-time XY coordinate value of a target dispensing needle head; thirdly, the deviation distance between the real-time XY coordinate value and the initial XY coordinate value is calculated, and the correction value is formed; and fourthly, in the dispensing running process of the target dispensing needle head, the correction value is offset into the dispensing running position. The single CCD based dispensing needle head correcting device comprises the CCD, a control unit (2) and a drive unit. The single CCD based dispensing needle head correcting method and device have the beneficial effects that XY position correction can be conducted on the replaced dispensing needle headwith high precision and high efficiency, the new dispensing needle head correcting time is shortened, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a calibration method and device, in particular to a single CCD-based dispensing needle calibration method and device. Background technique [0002] With the advancement of science and technology, the demand for dispensing technology in various industries has gradually changed to be more refined, which is manifested in smaller dot diameters and wire diameters, and higher consistency requirements for the width, thickness, and edge resolution of dispensing rubber strips. , so that the accuracy of dispensing equipment needs to be further improved. At the same time, in the solution of dispensing equipment, each module needs efficient cooperation to improve dispensing efficiency. During the dispensing process, the dispensing needle will be replaced periodically. After replacing the dispensing needle, the position of the dispensing needle needs to be repositioned. At present, in the traditional method, the dispensing needle is calib...
