Problems solved by technology

Although the residual stress of laser welding is smaller than that of traditional welding, since the workpiece usually has a small area, volume or thickness, the deformation caused by the residual stress has a significant impact on the precision required by the workpiece, thereby reducing the quality of the product.

Embodiment Construction

[0032] see figure 1 . figure 1 is a schematic diagram illustrating a welding device 1 according to a specific embodiment of the present invention. like figure 1 As shown, the welding equipment 1 includes a first temperature control device 10 and a second temperature control device 12 . The first temperature control device 10 further includes a first temperature controller 100 and a first body 102 , while the second temperature control device 12 further includes a second temperature controller 120 and a second body 122 . Wherein, the first temperature controller 100 maintains and provides a relatively low temperature to the first body 102 , and the second temperature controller 12 maintains and provides a relatively high temperature to the second body 122 . In practice, the relatively low temperature can reach, but is not limited to, 20 degrees Celsius. On the other hand, the relatively high temperature is up to, but not limited to, 80 degrees Celsius. Please note that in ...

Abstract

The invention discloses a welding device and a welding method thereof which are used for welding a first work piece and a second work piece. The welding device consists of a first temperature controlling device and a second temperature controlling device; the first temperature controlling device further comprises a first temperature controlling tool and a first body; and the second temperature controlling device further comprises a second temperature controlling tool and a second body. The first temperature controlling device and the second temperature controlling device can coordinate with each other to clamp the first work piece and the second work piece, thereby sticking the first work piece to the second work piece. The first temperature controlling device provides a relative low temperature to the first work piece; the second temperature controlling device provides a relative high temperature to the second work piece; and the two work pieces are welded. Therefore, the surface of the welded work pieces has excellent flatness.

Description

technical field [0001] The present invention relates to a welding device and a welding method, and in particular to a welding device and a welding method capable of maintaining the flatness of the workpiece surface after welding. Background technique [0002] Welding work is a very important link in the manufacturing process of electronic components and electronic equipment. The purpose and method of welding is to heat metals to melt them for joining. In recent years, high-power laser welding technology has been widely used in various fields, such as the automobile industry, medical equipment, and electronic components, which require precision processing. [0003] Laser welding has many advantages, for example: it is not affected by the geometric shape of the workpiece and the position of the welding point, as long as the laser can reach it, it can be welded; the laser can concentrate the energy in a very small area, which is quite suitable for high-precision welding work; ...
