Electronic element installing method

Abstract

The invention relates to an electronic element installing method, in particular to an electronic element installing method which is applied to the field of desktop type chip mounters and comprises the steps that an image and recognition features of a suction nozzle are acquired through image capturing devices, and then an electronic element is installed on a printed circuit on the basis of a processing result of image information. According to the electronic element installing method, the rotating trace of the suction nozzle is acquired through a tracing mechanism, the step of optical axis alignment of the part and circuit board image capturing devices is omitted very skillfully, and the problem that the circuit board image capturing device cannot directly obtain the practical rotating center of the suction nozzle is solved; the relative position relation between the practical rotating center of the suction nozzle and an image capturing center of the circuit board image capturing device can be efficiently determined and deviation between the practical rotating center and a designed rotating center can be corrected on the basis that too much cost of an existing desktop type chip mounter structure is not increased, therefore, operating personnel can easily learn, and printed circuit board production chip mounting can be efficiently performed.

Description

technical field [0001] The present invention relates to a method for installing electronic components, in particular to a method applied in the field of desktop placement machines. The image of the suction nozzle and the identification features are acquired by an image capture device, and the electronic components are installed on the surface based on the processing results of the above image information. A method of mounting electronic components on a printed circuit. Background technique [0002] Mounting accuracy is one of the core performance requirements of placement machines. The suction nozzle of the desktop placement machine inevitably has mechanical errors during the assembly process, which leads to the inconsistency between the actual rotation center of the suction nozzle and the designed rotation center. The judgment deviation of position will ultimately affect the accuracy of electronic component installation. [0003] There are usually two image capture device...

Problems solved by technology

However, pure image capture devices can only capture images, not light sources, and cannot be aligned with each other through the optical path. Therefore, the optical axis alignment is usually performed with an additional light source device, which will increase the manufacturing cost of the placement machine ; Or it is achieved by naked eye alignment, which leads to further expansion of mechanical errors
