Problems solved by technology

[0004] However, in the above method, one of the objects must be captured first before the other object can be captured. There is no way to capture images of both objects at the same time. Therefore, this method will consume too much time in the process of capturing images. to delay the follow-up action of combining

Embodiment Construction

[0013] Hereby enumerate the following preferred embodiments in conjunction with the accompanying drawings, in order to describe in detail the structure and effect of the present invention as follows:

[0014] Please see first figure 1 , a method for combining two objects using four cameras according to a preferred embodiment of the present invention includes the following steps:

[0015] A. Set the reference position:

[0016] a1: if figure 2 As shown, two reference objects 10 , 20 are prepared, and the two reference objects 10 , 20 are respectively placed on a platform 30 . Each reference object 10 , 20 has two positioning marks 12 , 22 . The two platforms 30 can move relative to each other along a fixed path between a first position and a second position. When the two platforms 30 are located at the second position, the two reference objects 10 and 20 can perform a combining action.

[0017] a2: Move the two platforms 30 to the second position to combine the two referenc...

Abstract

A method of combining two objects using four cameras in the present invention is to firstly adjust the positions of the two reference objects so that the two reference objects can be correctly combined, and then use four cameras and a display screen to measure the positions of the two reference objects respectively through photography. Two positioning marks are taken to obtain four reference images, and then the two positioning marks of the two objects to be combined are captured to obtain four positioning images, and the position difference between each reference image and each positioning image is obtained, and calculated Calculate the displacement of one of the objects to be combined to the other object to be combined, and then move one of the objects to be combined, so that the positioning marks of the two objects to be combined can be overlapped, and the action of combining the two objects to be combined can be completed.

Description

technical field [0001] The present invention is related to the combination method of two objects, in particular to a method of combining two objects using four cameras. Background technique [0002] When the IC (integrated circuit) is combined with the circuit board or the substrate, the IC and the substrate must be aligned before they can be combined. If they are not aligned, it will cause wrong connections of the IC pins and cause wrong actions, or even There is a short circuit problem. [0003] In the known positioning technology, there is a method of using dual CCD cameras to locate two objects. In this method, two objects (such as IC and substrate) to be combined are prepared first, and two positioning marks are respectively arranged on the two objects. Place it in the imaging area of ​​the dual CCD camera for imaging, move out after the imaging is completed, then move another object into the imaging area of ​​the dual CCD camera for imaging, and finally obtain the CCD...
