Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic component auxiliary installation equipment, and in particular to a solar photovoltaic component backboard threading tool. Background Art

[0002] Solar photovoltaic modules are the core and most important part of solar power generation systems. Solar photovoltaic modules are generally composed of tempered glass, EVA, cell layers, EVA, glass fiber and back panels stacked from bottom to top. In the stacking process of the modules, when employees lay the back panel, they must pass the lead wires of each bus bar of the cell layer through the back panel opening on the back panel of the solar photovoltaic module. Because the back panel opening is very narrow and the gap is small, employees need to make multiple adjustments to pass the lead wires of each bus bar through the back panel opening. In the process of employees adjusting the lead wires of each bus bar through the back panel opening, it is very easy to cause the cells connected to the bus bar to break, causing great economic losses. Summary of the invention

[0003] The purpose of the present invention is to provide a solar photovoltaic module backboard threading tool which has a simple structure, is easy to operate, and can smoothly pass all busbar lead wires through the backboard opening at one time.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the solar photovoltaic module backplane threading tooling comprises a lower template, an upwardly tilted guide plate is arranged at the front end of the lower template, and a plurality of positioning grooves are arranged in parallel on the upper surface of the lower template, each positioning groove can be embedded with a lead-out wire of a bus bar, and the rear end of each positioning groove extends backward and passes through to the rear end surface of the lower template, the position and number of each positioning groove just correspond to the position and number of each bus bar lead-out wire on the battery layer, and an upper template that can cover each positioning groove downward is arranged on the top of the lower template, and the upper template is connected and fixed to the lower template by a plurality of positioning connection components. When the upper template is connected and fixed to the lower template, the upper template and the lower template jointly form a plurality of positioning cavities corresponding to the position and number of each bus bar lead-out wire on the battery layer.

[0005] Furthermore, in the aforementioned solar photovoltaic module backplane threading tool, the rear end of the positioning groove extends backward and passes through to the connecting edge of the rear end face and the lower surface of the lower template, and the bottom of the positioning groove is gradually inclined downward from front to back.

[0006] Furthermore, the aforementioned solar photovoltaic module backplane threading tool, wherein: the structure of the positioning and connecting component includes: a positioning hole is arranged at the top of the lower template, a hemispherical limiting hole is arranged on the hole wall of the positioning hole, a positioning tube inserted into the positioning hole is arranged at the bottom of the upper template, a through hole is arranged on the lower tube wall of the positioning tube, a spring sheet is arranged in the positioning tube, one end of the spring sheet is fixed to the inner wall of the positioning tube, and the other end of the spring sheet is fixed with a hemispherical positioning block that extends into the through hole and is matched in size with the hemispherical limiting hole. The hemispherical positioning block always has a tendency to extend outward and insert into the hemispherical limiting hole under the outward elastic force of the spring sheet. When the positioning tube of the upper template is inserted into the positioning hole of the lower template and moves down until the hemispherical positioning block on the positioning tube corresponds to the hemispherical limiting hole on the hole wall of the positioning hole, the hemispherical positioning block on the positioning tube will extend and insert into the hemispherical limiting hole under the outward elastic force of the spring sheet, so that the upper template is connected and fixed with the lower template.

[0007] Furthermore, in the aforementioned solar photovoltaic module backplane threading tool, the angle between the guide plate and the horizontal plane is 15 to 30 degrees.

When laying the backplane, first pass the guide plate 2 of the tooling through the backplane opening, and then take the entire tooling out of the backplane opening. During the tooling removal process, the bus lead-out wires will be synchronously and smoothly brought out of the backplane opening at one time, thereby completing the bus lead-out wire threading operation of the backplane.
