The invention relates to a moving lifting device which comprises a moving mechanism and a lifting mechanism. The moving mechanism comprises a supporting plate, connecting parts and supporting claws. Multiple first motors connected with the connecting parts are arranged on the supporting plate, and rotating shafts of the first motors are perpendicular to the supporting plate. The connecting parts are connected with second motors, rotating shafts of the second motors are perpendicular to the rotating shafts of the first motors, third motors connected with the supporting claws are fixed on the second motors, and rotating shafts of the third motors is parallel to the rotating shafts of the second motors. The lifting mechanism comprises an underbed, two fork-shaped articulation pieces, a cylinder and a foot rack. The underbed is arranged on the supporting plate, the two ends of each fork-shaped articulation piece are connected with the underbed in a hinged mode, the other two ends of each fork-shaped articulation piece are connected with the foot rack in a slidable mode, and the cylinder drives the two fork-shaped articulation pieces to drive the foot rack to be lifted. The moving mechanism drives the supporting claws to move through motors, and drives the two fork-shaped articulation pieces to drive the foot rack to rise and fall through the cylinder. The moving lifting device is convenient to move, simple in structure, and capable of automatically adapting and adjusting balance.

The invention relates to mobile equipment which comprises a supporting plate, connection portions and branch claws. The supporting plate is provided with a controller and a gravity sensor. The side edge of the supporting plate is provided with multiple first servo motors, and rotating shafts of the first servo motors are perpendicular to the supporting plate. The connection portions connected withsecond servo motors are connected with the first servo motors, rotating shafts of the second servo motors fixedly provided with third servo motors are perpendicular to the rotating shafts of the first servo motors, and the third servo motors are parallel to the rotating shafts of the second servo motors. The branch claws are connected with the third servo motors.

The invention discloses a high-conductivity low-temperature sliver paste and a preparation method thereof. The preparation method comprises the steps of successively mixing a high-toughness resin, a thickening agent, a flexibilizer and an organic solvent; successively adding a low-melting-point alloy, a soldering flux and conductive silver powder, and performing high-speed mixing for obtaining paste; and grinding the paste to the paste with fineness of 5-10 mu m, and obtaining the conductive sliver paste. The conductive silver paste prepared by the invention has advantages of high conductivity and high mechanical property. After the low-melting-point alloy is added, conductivity performance and hardness performance are greatly improved. Through adding appropriate amount of thickening agent and flexibilizer, diffusion performance and bending performance of a sliver strip can be effectively controlled. The low-temperature sliver paste prepared by the invention has advantages of effectively reducing silver content, improving conductivity and mechanical performance and greatly saving cost. The high-conductivity low-temperature sliver paste can be widely applied in the industries of a thin-film switch, a capacitive electrode, a touch screen, etc.
