Sequential Nozzle Head Unit for Impact-Free Electronic Part Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chip mounter technologies face reduced productivity due to limited suction capacity and increased impact on electronic parts during the suction process, along with potential damage from mirror collisions when the mirror malfunction is not immediately detected.
Innovation Solution
The apparatus includes a head unit and nozzle unit that can be sequentially lowered to relieve impact during suction, with a controller managing the movement of both units and a mirror system that deviates from the nozzle path to prevent collisions, using motors and a cam member to adjust positions and ensure accurate alignment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all nozzles are lowered simultaneously to suction electronic parts, then the suction operation is simple and fast, but the impact on electronic parts is increased and may cause damage
Solution Approach 1:
The nozzle unit is divided into multiple independently controllable nozzle groups that can be lowered sequentially rather than all at once. The controller manages each nozzle group's descent timing, allowing parts to be suctioned in stages, which reduces impact while maintaining productivity.
2Reliability
If the mirror is moved to one side using a separate motor, then the mirror can deviate from the nozzle path, but the malfunction is not immediately recognized and collision may occur
Solution Approach 1:
A sensor detects the mirror's position and provides feedback to the controller. The controller monitors this position information and can immediately recognize when the mirror is in an abnormal position, allowing real-time correction before collision occurs with the nozzles.
Solution Approach 2:
The separate motor-driven mirror positioning system is replaced with a passive mirror support that moves automatically based on the head unit's position. This eliminates the complex motor control system while maintaining the mirror's ability to deviate from the nozzle path.
3Device complexity
If nozzles are installed on transfer belts in a one-to-one relationship, then the structure is simple, but the quantity of electronic parts suctioned is small and productivity is reduced
Solution Approach 1:
Multiple nozzles are combined into a single nozzle unit that is mounted on the head unit rather than being distributed on separate transfer belts. This merged structure allows multiple nozzles to be lowered and operated simultaneously from one location, increasing suction capacity while simplifying the overall system structure.

AI summary
An apparatus for manufacturing electronic parts is provided. The apparatus includes a head unit installed on a main body and configured to move up and down, a nozzle unit installed on the head unit and configured to move up and down, and a positioning unit sequentially displacing the head unit and the nozzle unit to a position where the electronic parts are on standby to suction the electronic parts using the nozzle unit. Thus, when the head unit is used to suction the electronic parts on standby at a standby position of the electronic parts, the head unit and the nozzle unit installed on the head unit are sequentially lowered, so that it is possible to relieve an impact occurring when the electronic parts are suctioned to the ends of nozzles.
