Problems solved by technology
[0004] The existing alignment device has the following disadvantages: (1) At least two cameras need to be set, which increases the cost of the alignment device and is suitable for specific specifications of the implement
(2) Adjust the X and Y axes to the position by manual visual inspection. This operation is time-consuming and has large errors, resulting in a decrease in product yield

The invention provides an optical positioning device capable of bidirectional imaging by using single camera device. The device comprises a camera device, a light collecting unit, a first imaging unit, and a second imaging unit. The light collecting unit is disposed between the first imaging unit and the second imaging unit, and comprises a full-reflection mirror and a light collecting half-reflection mirror. The light collecting half-reflection mirror is disposed with respect to the camera device at a light collecting reflection angle. The first imaging unit is disposed between an upper plate member and the light collecting unit, and is provided with a first light source generating unit and a first half-reflection mirror. The second imaging unit is disposed between a lower plate member and the light collecting half-reflection mirror, and is provided with a second light source generating unit and a second half-reflection mirror. The single camera device is used for the bidirectional imaging for the upper plate member and the lower plate member. The optical positioning device is advantageous in that the number of the camera devices can be reduced, and the X axis and the Y axis can be adjusted to be positioned in an automatically-aligned manner, and therefore the capacity and the product yield can be improved.
Description
technical field [0001] The invention relates to an optical positioning device, in particular to a structural design capable of bidirectionally capturing images of an upper board and a lower board by using a single camera device. Background technique [0002] In many industrial fields, photographic devices are often used for image capture and positioning. Due to the limitation of the optical path imaging of the photographing device, generally only a single photographing device can be used to capture images of a specific position range. If the photographing device is used for identifying and positioning an optical point, it can only identify and position a single optical point. In order to carry out image recognition and positioning of the optical points on the upper and lower plates, it is necessary to configure two photographic devices to achieve the intended purpose. [0003] Take the application of photographic devices in circuit board printing machines as an example of ...
