Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dividing groove forming devices fail to ensure accurate and uniform depth of grooves due to positional deviations between rotary blades, leading to waviness phenomena and potential substrate malfunctions.
Innovation Solution
A dividing groove forming device with radially opposed cutters and a phase adjustment unit, where the rotation axes of the cutters are parallel and the phase of at least one cutter is adjusted to ensure precise opposition of rotary blades, preventing waviness and allowing for constant depth groove formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two cutters with rotary blades are used to form dividing grooves from front and back surfaces, then dividing grooves can be formed simultaneously on both surfaces, but positional deviation between rotary blades causes waviness phenomenon and non-uniform groove depth
Solution Approach 1:
The invention introduces a phase adjustment unit that enables dynamic adjustment of the rotational phase of at least one cutter relative to the other. This allows the system to adapt the positional relationship between rotary blades during operation, ensuring they remain in opposed opposition throughout rotation. The dynamic phase adjustment capability resolves the contradiction by maintaining precise blade positioning while preserving simultaneous groove formation capability.
Solution Approach 2:
The invention changes the operational parameter of cutter phase relationship from fixed to adjustable. By providing a phase adjustment unit that can modify the rotational phase of cutters, the system optimizes the positional parameter of rotary blades to achieve opposed opposition. This parameter change enables precise control over blade positioning, eliminating waviness while maintaining high productivity through simultaneous groove formation.
2Device complexity
If the positional relationship between rotary blades is not adjusted, then the device structure remains simple, but waviness phenomenon occurs causing groove depth variation and potential substrate malfunction
Solution Approach 1:
The invention implements preliminary action by providing a phase adjustment unit that pre-adjusts and maintains the optimal phase relationship between cutters before groove formation begins. This preliminary positioning ensures rotary blades start in opposed opposition and remain so throughout operation, preventing waviness phenomenon before it occurs. The phase adjustment unit performs the necessary positioning action in advance, ensuring reliable groove formation without compromising substrate functionality.
3Manufacturing precision
If rotary blades are positioned in opposed opposition, then groove depth remains constant and uniform, but the device requires a phase adjustment unit increasing structural complexity
Solution Approach 1:
The invention applies self-service by designing the phase adjustment unit to automatically maintain the opposed opposition positioning of rotary blades throughout rotation. Once the optimal phase relationship is established, the system self-maintains this positioning through synchronized rotational movement, eliminating the need for continuous external intervention. This self-maintaining mechanism achieves constant groove depth while minimizing operational complexity.

AI summary
A dividing groove forming device includes: a first cutter including a plurality of first rotary blades; a second cutter including a plurality of second rotary blades; a first rotation drive unit for rotationally driving the first cutter; a second rotation drive unit for rotationally driving the second cutter; a cutter support unit; and a phase adjustment unit. The cutter support unit supports the first cutter and the second cutter such that the first and second cutters are radially opposed to each other so that rotation axes of the first and second cutters are parallel to each other. The phase adjustment unit adjusts a phase of at least one of the first cutter and the second cutter such that the first rotary blades and the second rotary blades are opposed to each other in an opposing area in which the first cutter and the second cutter are opposed to each other.
