Short closed-loop control high-speed roller bed conveying mechanism

Abstract

The invention discloses a short closed-loop control high-speed roller bed conveying mechanism. The short closed-loop control high-speed roller bed conveying mechanism is characterized in that the short closed-loop control high-speed roller bed conveying mechanism comprises a roller bed body and a positioning assembly fixed to a trolley system and used for positioning the advancing direction of the trolley system; a driving roller driven by a drive unit to act and a driven roller synchronously acting together with the driving roller are fixed to the roller bed body; a control unit is connected with the drive unit; positioning information given by the positioning assembly is read through the control unit; and the control unit either sends the positioning information to the drive unit or controls the drive unit according to the positioning information. The short closed-loop control high-speed roller bed conveying mechanism is used for welding forming and repair welding work of front longitudinal beams, front floors, rear floors, engine compartments and other small sub assemblies, and is simple and compact in structure, high in transmission speed and high in positioning accuracy.

Description

Technical field [0001] The invention relates to a short closed-loop control high-speed roller bed conveying mechanism used in a production line of automobile body-in-white sub-assembly parts, belonging to the field of automobile body-in-white production lines. Background technique [0002] In the current automotive body-in-white welding production line, the roller bed, as the most common form of conveying, is mostly used for conveying the bottom plate and side walls of the body-in-white. Due to the need to adapt to the conveying conditions of the bottom plate, most of the existing roller beds are six-roller roller beds with a length of about 5 m. However, for the relatively small component sub-assemblies such as the front longitudinal beam, the front floor, the rear longitudinal beam, the rear floor, the engine compartment, and the rear wheel cover inner panel, manual handling, robotic gripper handling and reciprocating rod transportation are still used. Mainly, its speed is slo...

Problems solved by technology

However, for relatively small sub-assemblies such as front longitudinal beams, front floors, rear longitudinal beams, rear floors, engine compartments, and rear wheel house inner panels, manual handling, robot gripper handling, and reciprocating rod transportation are still currently used. Mainly, its speed is slow, the precision is low, the proportion of effective operation time is low, and the cost is high, which affects the overall production logistics budget, layout and planning and design
