Description

Technical Field

[0001] The invention relates to the technical field of tinned solder strip shearing machines, in particular to a tinned solder strip shearing machine for photovoltaic module battery cells. Background Art

[0002] Photovoltaic tinned solder ribbon is also called tinned copper ribbon or tin-coated copper ribbon, branch collector ribbon and interconnection strip, which is used to connect the solar cells of photovoltaic modules and plays an important role in conductivity and concentration. The solder ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the solder ribbon will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module. Photovoltaic tinned solder ribbon needs to be cut to relative sizes according to demand during production, and a shearing machine is required.

[0003] However, there are still some problems when using the existing photovoltaic module cell tinning solder strip cutting machine:

[0004] There is a welding strip shearing and splitting device with a Chinese patent publication number of CN202639473U, which includes: a power component, used to drive the welding strip to move longitudinally along the length direction of the welding strip and store the cut welding strip; a shearing table, on which a fixed blade shearing notch is provided and a shearing component bracket is fixedly connected; a shearing component is fixedly connected to the shearing component bracket and is used to cooperate with the fixed blade shearing notch to shear the welding strip; a driven component is used to place the welding strip to be sheared and cooperate with the driving of the power component to move the welding strip longitudinally along the length direction of the welding strip;

[0005] The existing welding strip shearing and splitting equipment can only shear and split the welding strip, but it is not convenient to cut the sheared and split welding strip to a fixed length according to the demand, and the operation is inconvenient;

[0006] When the existing shearing and splitting equipment rewinds the split welding strip, if it is cut at a fixed length, it is easy to cause the welding strip to become loose after winding, making it difficult to rewind it later. In addition, part of the welding strip cannot be rewound after cutting, making the subsequent rewinding cumbersome.

[0007] Because the winding and unwinding rollers need to be controlled to stop rotating when the welding rod is cut, the operation is complicated and more control structures need to be used, which increases the cost.

[0008] In view of the above problems, an innovative design was carried out based on the original photovoltaic module cell tinning solder strip shearing machine. Summary of the invention

[0009] The object of the present invention is to provide a tin-plated solder strip shearing machine for photovoltaic module cell sheets, so as to solve the problem that the existing cutting equipment mentioned in the above background technology is not convenient for cutting the cut welding rod to a fixed length, and because there is no winding positioning structure, it is easy to cause the welding rod to be loose during cutting.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a photovoltaic module cell sheet tinning solder strip shearing machine, comprising a supporting platform:
