Title:
JOINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/238809
Kind Code:
A1
Abstract:
This joining device is a device that joins a first joined object and a second joined object using laser light, and comprises a first stage, a pressurization mechanism, a second stage, and a laser light source. The first stage is a device which is transmissive to laser light and is positioned on the back surface side of the first joined object. The pressurization mechanism is a mechanism that applies a pressure to the back surface of the first joined object. The second stage has a pressure-receiving surface that receives the pressure of the pressurization mechanism on the back surface side of the second joined object. The laser light source irradiates a junction portion between the first joined object and the second joined object with laser light via the first stage. The pressurization mechanism is a mechanism in which a pressure transfer medium is composed of a gas or a liquid, and which applies the pressure to the back surface with the transfer medium in contact with the back surface of the first joined object.
