Abstract

The utility model relates to a unilateral clamp of a PCB. The unilateral clamp is composed of a working table, a guide rail and a tray, wherein the guide rail is fixed on the working table, the tray is positioned on the guide rail, and a support plate is installed at the front section of the tray and used for supporting the PCB. A clamp rotating shaft and a rotating shaft supporting block of the clamp rotating shaft are further arranged at the position, close to the front end of the support plate, of the tray, the clamp rotating shaft penetrates through the rotating shaft supporting block, and a rotating shaft push rod and a clamping arm are fixed on the clamp rotating shaft. The outer end of the rotating shaft push rod extends out of the bottom of the tray, and a push rod touch boss is fixed at the position, corresponding to the outer end of the rotating shaft push rod, of the working table. A torsion spring is further arranged on the rotating shaft push rod, and the other end of the torsion spring abuts against the rotating shaft supporting block or the tray, so that the outer end of the clamping arm is compressed on the support plate (namely the PCB). The whole operation process is simple and rapid, and the defect that detection is not accurate due to displacement caused by unstable clamping can be overcome. The unilateral clamp of the PCB is simple and reasonable in structure, low in cost and practical.
