[0008] The workpiece positioning and clamping mechanism includes a support plate, a clamping plate, and a clamping cylinder. The support plate has a pair of clamping plates located at the other end of the clamping guide rail, and the top of the support plate is provided with a slot for placing the sofa leg workpiece. The clamping plate is located between the support plates to limit the connection plate of the sofa leg workpiece. The clamping cylinder is located on one side of the support plate, and the output end of the clamping cylinder is horizontally provided with a pressure plate, which extends above the support plate. The clamping cylinder drives the pressure plate to clamp the sofa leg workpiece placed on the support plate.

[0009] The workpiece assembly mechanism includes an assembly cylinder, an assembly guide rail, and a cap assembly box. The assembly cylinder is horizontally mounted on the assembly table via a second cylinder seat. The assembly guide rail is located on one side of the second cylinder seat and is parallel to the output end of the assembly cylinder.
