Solution Overview
Problem
Existing electronic component mounting apparatuses face reduced operating rates and production efficiency when component feeding devices are not provided on both sides of the carrying device, particularly when using tray feeders with low component pickup frequency.
Innovation Solution
The apparatus includes a carrying device with a component feeding device on one or both sides, featuring movable beams and suction nozzles that pick up and mount components on a printed board, allowing for simultaneous operation and efficient component handling without the need for dual-sided feeding devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If component feeding devices are provided on both sides of the carrying device, then the operating rate of beams is improved, but the device complexity and setting space requirements increase
Solution Approach 1:
The mounting head is designed with multiple suction nozzles that can selectively pick up components from different component feeding devices. This allows a single beam-mounted mounting head to serve multiple feeding devices, increasing the operating rate without requiring separate beams for each feeder, thus resolving the contradiction between productivity and device complexity
Solution Approach 2:
Multiple suction nozzles are integrated into a single mounting head assembly that is mounted on a beam. This merging of multiple component pickup capabilities into one unit allows the beam to efficiently serve multiple component feeding devices, improving operating rate while avoiding the need for additional beams and reducing overall device complexity
2Productivity
If component feeding devices are provided on both sides of the carrying device, then the operating rate of beams is improved, but the setting space requirements increase
Solution Approach 1:
The mounting head with multiple suction nozzles can selectively pick up components from component feeding devices located at different positions (including both sides of the carrying device). This multi-functional capability allows efficient component pickup without requiring symmetric placement of feeding devices, thus improving operating rate while reducing setting space requirements
Solution Approach 2:
The suction nozzles are arranged in multiple directions and positions on the mounting head, enabling component pickup from various spatial locations. This three-dimensional arrangement allows the single mounting head to access components from different sides of the carrying device, improving productivity without increasing the horizontal setting space
3Adaptability or versatility
If using tray feeder with low component pickup frequency, then the operating rate of corresponding beam is decreased, but the adaptability to different component types is improved
Solution Approach 1:
The mounting head with multiple suction nozzles can pick up components from any component feeding device including tray feeders, regardless of component type or feeder location. This increases the beam's operating rate by enabling it to efficiently service multiple feeders, while the system maintains adaptability to different component types through the versatile nozzle arrangement
Solution Approach 2:
The suction nozzles are pre-positioned in multiple locations on the mounting head, allowing the beam to pick up multiple components in a single traversal motion. This preliminary positioning enables the beam to efficiently handle tray feeders and other feeding devices without reducing operating rate, while maintaining adaptability to various component types
