Description

TECHNICAL FIELD

[0001] The utility model relates to rain brush sheet metal part automatic feeding technical field, especially to a rain brush part flexible feeding system. BACKGROUND

[0002] In the rain brush automatic assembly process, sheet metal parts are difficult to realize automatic feeding due to size shape and surface spraying layer. The working principle of the system is that the rain brush sheet metal parts are put into the upper belt feeder bin by artificial, and then the automatic feeding mode is started. The upper belt feeder bin rotates a small distance at speed V, and the lower belt feeder bin rotates a distance at speed 2-3 times V. The rain brush sheet metal parts move forward and fall on the lower belt feeder. Due to the speed difference between the two belts, the rain brush sheet metal parts are spread on the lower belt feeder. The rain brush sheet metal parts move forward step by step. When the rain brush sheet metal parts fall on the flexible vibration disc through the discharging guide groove, the top ring light source opens to supplement light. The industrial camera detects the posture and coordinate position of the rain brush sheet metal parts, and then sends the coordinate of the separated parts with grabbing space to the four-axis manipulator system. The system uses the manipulator flexible gripper to grab the rain brush sheet metal parts according to the coordinate of the parts, and prepares to put into the assembly fixture. When the parts in the flexible vibration disc do not have independent posture that can be grabbed, the flexible vibration disc vibrates at different frequencies according to the number and distribution of the parts in the disc. Then the top ring light source opens again to supplement light. The industrial camera detects the posture and coordinate position of the parts, and then sends the coordinate of the separated parts with grabbing space to the four-axis manipulator system. The manipulator grabs again. When the number of parts in the flexible vibration disc is too small, the upper and lower belt feeders move to supplement the parts in the vibration disc. The process is repeated to complete the automatic feeding of the rain brush sheet metal parts.
