A Multi-Region Image Inspection Method Traversing Grain Irregular Regions

Abstract

The invention discloses a multi-region image detection method for traversing irregular regions of crystalline grains. The method comprises the following steps of shooting a crystalline grain image through using image collecting equipment and transmitting the crystalline grain image to an equipment control computer of a crystal fixing machine; carrying out analysis treatment on the image in the equipment control computer; judging whether the crystalline grains in a plurality of regions in the image have conditions or not; driving a worktable motor to operate according to whether the crystalline grains have conditions or not to realize the stepping movement of a worktable; and finally, traversing the crystalline grains in the irregular regions. According to the method disclosed by the invention, under the condition that a motor speed and an image processing efficiency are unchanged, the traversing efficiency of the crystalline grains is improved and a meaningless empty stepping condition of the worktable is effectively avoided; and in the whole crystalline grain region traversing process, a traversing jumping movement of the worktable is guided through the judgment of a plurality of the regions, so that the worktable is prevented from being released from the region of the crystalline grains and the integrity of traversing the region of the crystalline grains for single time can be improved.

Description

technical field [0001] The present invention relates to the technical field of crystal grain traversal methods for die bonding machines, in particular to a multi-region image detection method for traversing irregular regions of crystal grains Background technique [0002] With the development of my country's semiconductor lighting industry, domestic semiconductor packaging manufacturers and equipment manufacturers have increased rapidly, and the crystal bonding machine that occupies the first process in semiconductor packaging equipment has developed rapidly. The pellets are picked up by the robot and fixed on the support. Therefore, it is one of the core technologies of the die bonder to quickly, accurately and completely traverse the die. [0003] The current grain traversal method is mainly to traverse a single grain in sequence, that is, the workbench steps once, the camera takes an image, and the image processing algorithm only checks the presence or absence of a grain ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a multi-region image detection method for traversing grain irregular regions, aiming to solve the problem that the existing method for traversing grains can only detect a single grain at a time, and the efficiency is low. And it is impossible to predict whether the traversal path is reasonable, so as to improve the speed of the single grain traversal process and improve the integrity of the entire area traversal
