Cable Preparation Device for Insulation Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable stripping devices face challenges in ensuring high-quality processing due to the risk of damaging cable strands during insulation removal, with current methods either severing the strands or failing to detach the insulation properly, leading to rejects and downtimes.
Innovation Solution
A cable processing device that includes a stripping device and a cable preparation device with pressing elements to detach insulation from strands before stripping, using movable plates or rollers to apply pressure and reduce adhesion, and a crimping device for attaching contact elements, allowing for precise force adjustment and efficient insulation removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the knife penetrates deeply into the insulation, then the insulation is cut effectively, but the cable strands may be severed
Solution Approach 1:
The pressing element is activated before the stripping knife to pre-detach the insulation from the strands. This preliminary action creates a separation layer that allows the subsequent cutting action to occur without the knife contacting the strands, thus achieving effective insulation removal while preventing strand damage.
Solution Approach 2:
The stripping process is divided into two distinct stages: first, a pressing stage that detaches the insulation from the strands using a pressing element, and second, a cutting stage that removes the detached insulation using the stripping knife. This segmentation allows each element to perform its function independently without interfering with the other.
2Object-affected harmful factors
If the knife does not cut deep enough into the insulation, then the strands are protected, but the insulation will not be pulled properly from the strands
Solution Approach 1:
The pressing element performs a preliminary detachment action that separates the insulation from the strands before the cutting action. This pre-separation ensures that even a shallow cut by the knife is sufficient to complete the insulation removal, as the insulation has already been loosened from the strands by the pressing action.
Solution Approach 2:
The pressing element acts as an intermediary that mediates between the insulation and the strands. By applying pressure, it creates a separation layer that facilitates the subsequent removal of insulation without requiring deep penetration by the cutting element, thus protecting the strands while ensuring complete insulation removal.
3Stability of the object's composition
If insulation adhesion to strands is high, then the insulation remains attached during manufacturing, but it cannot be stripped properly
Solution Approach 1:
The pressing element applies a preliminary mechanical action to the insulation before stripping occurs. This pre-pressing disrupts the adhesion bonds between the insulation and strands that were formed during manufacturing, thereby reducing the bonding strength and enabling easy subsequent removal of the insulation without damaging the strands.
Solution Approach 2:
The pressing element changes the physical state of the insulation-strand interface by applying localized pressure. This parameter change (mechanical stress) alters the adhesion characteristics, transitioning the insulation from a strongly adhered state to a loosely attached state, making it suitable for easy removal during the stripping process.
