Description

SMT paster selvedge clamping device Technical Field The utility model relates to the technical field of SMT (surface mounted technology) patches, in particular to an SMT patch edge clamping device. Background The SMT patch refers to a short for serial process flow of processing on the basis of a PCB, which is a printed circuit board. SMT is a surface mount technology (surface mount technology), which is one of the most popular technologies and techniques in the electronics assembly industry. Electronic circuit surface assembly techniques are known as surface mount or surface mount techniques. The circuit mounting technology is to mount no-pin or short-lead surface assembly components on the surface of a printed circuit board or the surface of other base plates, and to carry out welding assembly by reflow soldering or dip soldering and other methods. The edge clamping device is used when the printed circuit board is pasted. The distance of some SMT paster selvedge clamping devices of current is inconvenient for operation, when carrying out the paster centre gripping to the printed circuit board, adopts multiple spot centre gripping, only can carry out a little next centre gripping, inconvenient workman's operation, and waste time and energy has reduced work efficiency. Disclosure of Invention The utility model aims to solve the technical problem of providing the SMT patch edge clamping device, which can directly finish inward closing and opening of the clamping shell in a traversing manner so as to solve the problem in the background art. The SMT patch edge clamping device comprises a panel and a plurality of clamping shells, wherein the clamping shells are arranged on the panel in parallel, clamping grooves are formed in opposite faces of the clamping shells, sliding grooves are transversely formed in the panel, sliding blocks are arranged on the bottoms of the clamping shells right opposite to the sliding grooves, the sliding blocks are arranged in the sliding grooves in a sliding manner, screw rod holes are transversely formed in the sliding blocks, screw rods are transversely arranged in the sliding grooves, one end of each screw rod is in threaded connection with each screw rod hole, a pinion is arranged at the other end of each screw rod, crown teeth meshed with each pinion are arranged on one side of each pinion, a pushing shell is arranged on the panel, and a linkage mechanism for driving a large gear and the screw rods to rotate is arranged between the pushing shell and the panel.
