Description

Mechanical structure for carrying workpiece for subsequent deep processing Technical Field The invention relates to the technical field of automatic conveying, in particular to a mechanical structure for conveying workpieces for subsequent deep processing. Background In the machining and manufacturing industries, after finishing the preliminary machining, the workpiece is often required to be transported to a subsequent station for a process such as surface treatment, deep machining, inspection, or assembly. For example, in a metal surface treatment line, workpieces need to be accurately and smoothly transported from a buffer or loading station to a treatment station before entering the stations for spraying, phosphating, or passivation. Such handling is not only a simple displacement, but often also accompanied by precise requirements for the pose of the workpiece, e.g., the need to align a particular surface of the workpiece to the spray gun prior to entering the spray booth, and the need to rotate the workpiece to expose different side features prior to entering the vision inspection station. Currently, common transportation means include conveyor belts, crown blocks, forklifts, or manual handling. The conveyor belt is suitable for continuous, large-batch, lightweight workpieces, but has poor adaptability to irregularly shaped, heavy or precisely positioned workpieces. The conveyor belt can only realize the conveying of straight lines or fixed paths, is difficult to realize the accurate fixed-point stop and the flexible adjustment of the gesture of the workpiece in the conveying process, and has limited supporting force for heavy workpieces. Crown blocks and forklifts have strong carrying capacity, but have limited flexibility, positioning accuracy and automation integration level, and large occupied area. The operation of the crown block is limited by the space of a factory building and the layout of a track, the positioning accuracy is usually low, seamless connection with a high-beat automatic production line is difficult, the forklift needs manual operation, the automation degree is low, and the consistency is difficult to ensure. Manual handling is labor intensive, inefficient, inconsistent and potentially safe. Particularly in production lines with high repeatability, tense beats or handling harmful environments, manual handling becomes a bottleneck and risk point. Particularly in the pre-handling step of metal surface treatment, workpieces often need to enter a treatment station in a specific posture. Most of the existing conveying equipment has single function, can only complete movement in a straight line or a plane, and lacks the capability of adjusting the posture of a workpiece in the conveying process. If a turnover or rotation mechanism is additionally added, the system is complex in structure, high in cost and occupies more production line space.
