Description

TECHNICAL FIELD

[0001] The utility model relates to diffusion welding technical field, concretely relates to a diffusion welding soft row support frock. BACKGROUND

[0002] Diffusion welding is a kind of technology that makes material interface atoms diffuse to form metallurgical bonding by high temperature and high pressure, and is widely used in the connection of precision electronic devices and multilayer soft row type layer welding parts. Such welding parts are usually composed of multiple ultra-thin metal layers, and pressure needs to be applied to both ends simultaneously to form uniform bonding during welding. However, due to the high flexibility and thin thickness of the soft row material, the middle region of the welding part is easily affected by uneven pressure or thermal stress during the welding process, resulting in collapse deformation or post-welding warping. In addition, after the welding is completed, the robot needs to quickly take out the material. If the support structure lacks buffering or gap adjustment capability, it is easy to cause difficulty in taking out the material or damage to the workpiece. Therefore, developing a frock structure with dynamic support and material taking adaptability has become the key to improving the welding efficiency and quality.

[0003] In the existing diffusion welding process, in order to prevent the deformation of the layer welding part, some simple support structures are usually used. For example, fixed block-shaped supports are placed under the layer welding part to provide a certain support force for the layer welding part. Some frocks use upper and lower corresponding electrode plates, graphite blocks are arranged on the electrode plates, and the layer welding part is placed on the graphite blocks for welding. Some frocks install simple support components on the electrode plates to reduce deformation by contacting the layer welding part through the support components.

[0004] However, the existing support frock has many deficiencies. First of all, most of the support structures are fixed and cannot be adjusted, and cannot be flexibly adjusted according to layer welding parts of different specifications and sizes, and have poor universality. When facing diversified welding needs, it is necessary to frequently change the frock, which increases the production cost and production cycle. Secondly, when welding both ends of the layer welding part at the same time, the existing support structure is difficult to provide uniform and stable support force, which causes the layer welding part to still be prone to local deformation during the welding process, affecting the welding quality. In addition, after the welding is completed, the taking-out process is not convenient, and due to the unreasonable gap between the support structure and the layer welding part, the mechanical arm is easy to cause damage to the welding part when taking out the material, which reduces the production efficiency. Moreover, the existing support frock lacks effective buffering design and cannot well adapt to the slight deformation of the product during the welding process, which cannot meet the requirements of high-quality welding. These defects directly affect the welding yield and production efficiency, and an diffusion welding support frock with multidirectional adjustment, elastic support and material taking adaptability is urgently needed.
