Composite busbar bending process

Abstract

The invention discloses a composite busbar bending process, and belongs to the technical field of production of composite busbars. The composite busbar bending process comprises the following steps of (1) lamination, stacking at least two layers up and down, wherein the structure of each layer is a first insulating layer, a copper bar and a second insulating layer in sequence from top to bottom, the right part of each adjacent layer is provided with an anti-bonding layer and the left part is glued for bonding, and the length of each anti-bonding layer is greater than or equal to that of the bent and staggered part; (2) laminating and gluing; (3) bending in place; and (4) extraction of the anti-bonding layers to obtain a bent composite busbar. By the composite busbar bending process, cracking of the bent part of the composite busbar and stagger deformation between the layers can be prevented; the quality is ensured; the yield is improved; the efficiency is improved; and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of making composite busbars. Background technique [0002] In the process of production practice, when performing the bending process on the composite busbar that needs to be bent, it often happens, such as figure 1 , figure 2 As shown, after the bending is completed, the relative bending arcs of the two copper bars on the inner and outer sides are slightly different (that is, the extension of the two copper bars is different when bending), which will cause the two copper bars on the inner and outer sides to be The phenomenon of misalignment, that is, after bending, one end of the two copper bars on the inner and outer sides is misaligned and misplaced, and the insulating layer at the bending arc will crack, which will affect the product quality; seriously, the two copper bars will be damaged. Deformation, wrinkles, and curved surfaces are formed, making the product scrapped and unusable, increasing produ...
