Photovoltaic bus bar bending clamp

Abstract

The invention discloses a photovoltaic bus bar bending clamp which comprises a first assembly, a second assembly, a third assembly and a fourth assembly. The first assembly comprises a left clamping arm, the upper end of the left clamping arm is fixedly connected with a left fixing block, the upper end face of the left fixing block is an arc-shaped face, and the upper end of the left fixing blockis fixedly connected with a left disc; and a circular left rotating hole is formed in the circle center of the left disc, a concave part is fixedly connected to the upper end of the left disc and comprises a concave opening formed in one side, an inner angle is formed by the concave opening, the angle of the inner angle is 90 degrees, and two threaded holes are formed in one side of the concave part. The photovoltaic bus bar bending clamp has the advantages that the bending clamp can be bent in batches only by adjusting a stopping block to the standard size line for the first time, repeated measurement is not needed subsequently, the requirement for large-scale bending is met, the production efficiency is improved, and the labor cost is reduced; and after the bending clamp used, batch operation can be carried out according to the standard size and the standard bending angle, and the productivity efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of busbars, in particular to bending pliers for photovoltaic busbars. Background technique [0002] During the production process of photovoltaic modules, single-piece cells are welded into battery strings with interconnection strips by a stringer welding machine, which are laid out on the adhesive film laid on the glass surface of the front plate, and then the battery strings are welded together by the confluence belt. After the confluence belt is welded, the second layer of adhesive film and the rear glass are laid. There are three lead-out holes for busbars at one end of the short side of the rear glass, and the busbars need to be led out from the back glass after welding. After stacking, the semi-finished components are laminated and cross-linked, and the bus strips drawn out after lamination are welded to the junction box to complete the current extraction of the components. The specific stacking and b...

Problems solved by technology

The existing operation method is to manually use a ruler to measure the standard size and then manually bend the confluence belt. After manual bending, there are large size deviations, inconsistent bending angles, and low operating efficiency.

After using manual bending, the shape of the confluence belt is deformed, the appearance is uneven, and the operation difficulty of the next process is increased.
