Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cable end polishing, and in particular to a photovoltaic cable end polishing device and method. Background Art

[0002] The cable end is a part of the cable connector. It can protect the cable from moisture, corrosion and other harsh environments after construction, reduce the risk of damage due to natural environment and other reasons. At the same time, the cable end can also ensure a good state of current flow, so as to achieve the purpose of transmitting information or energy.

[0003] When making the cable end, it is necessary to ensure that the surface of the end is completely smooth and free of impurities. Otherwise, it will affect the current flow and the transmission effect of the cable. During the process of making the cable end, polishing can remove the stains and oxides on the surface of the end, strengthen the adhesion and contact between the cable and the end, make the cable connection reliable, and extend the service life of the cable.

The rotation of the first rotating shaft 207 drives the second gear 209 thereon to make a circular motion. The second gear 209 meshes with the first inner tooth ring 202. When the second gear 209 moves along the trajectory of the first inner tooth ring 202, the second gear 209 can rotate itself, and then drives the abrasive belt wheel 208 outside the first rotating shaft 207 to rotate. The rotation of the multiple abrasive belt wheels 208 drives the polishing belt 210 to make a trajectory motion, so that the polishing belt 210 can make a trajectory motion while rotating, and cooperate with the movement of the cable end to quickly and comprehensively polish the cable end.

[0044] Working principle: When the present invention is in use, the stripped cable end is passed through between three rotating rollers 513 distributed in a ring. Subsequently, the electric cylinder 516 expands and contracts to drive the turntable 515 rotatably connected thereto to rotate inside the second outer ring 514.

The deflection of the deflection seat 509 drives the second rotating shaft 511 thereon to deflect. The deflection of the second rotating shaft 511 drives the rotating roller 513 to deflect, enabling the rotating roller 513 to be in close contact with the cable; Subsequently, a rotating column 305 is rotated by a tool. The rotation of the rotating column 305 drives the fifth gear 403, the third gear 306, and the fourth gear 307 thereon to rotate. The rotation of the fifth gear 403 drives the second external gear ring 402 to rotate. The rotation of the second external gear ring 402 drives another fifth gear 403 and the rotating column 305 at its center to rotate, so that both rotating columns 305 can rotate; The rotation of the third gear 306 drives the second rack 304 to move along the T-shaped guide rail 302. The rotation of the fourth gear 307 drives the two first racks 303 to move towards each other along the T-shaped guide rail 302. The movement of the first rack 303 and the second rack 304 drives the connecting block 308 at their ends to move. The movement of the connecting block 308 drives the moving plate 212 to slide on the T-shaped bracket 211.
