Abstract
The invention discloses a panel feeding clamp, which comprises a base for external installation, a pincer seat with one end fixed on the base, a substrate fixed on the base, a compression bar with the middle hinged with the other end of the pincer seat and an external casing. The compression bar is provided with a pincer opening end and a non-pincer opening end, wherein the pincer opening end and the pincer seat form a pincer opening, and the non-pincer opening end is controlled by a driving mechanism to achieve opening or closing of the pincer opening, the driving mechanism comprises a cylinder arranged on the pincer seat and a spring assembly arranged on the substrate, the cylinder is connected with the spring assembly, the casing is rotatably provided with a C-shaped crank arm, one end of the crank arm is hinged to a connection portion of the cylinder and the spring assembly, the other end of the crank arm is hinged to a connection plate capable of sliding along the surface of the pincer seat, and elasticity effects of the spring assembly drive the connection plate to move close to the compression bar to enable the pincer opening to clamp a panel through the crank arm. When the cylinder applies reverse force on the crank arm, the crank arm drives the connection plate to move far away from the compression bar to enable the pincer opening to open. The clamp force is stable and reliable, has no damage to the surface of the panel, and avoids influences of power-down, decompression or pressure oscillation.
