Description

Technical Field

[0001] This utility model relates to the field of heat shrink sleeve flattening technology, and in particular to a semi-automatic device for heat shrink sleeve flattening. Background Technology

[0002] In the wire harness manufacturing process of electronics, automotive, and communications industries, the flattening of heat shrink sleeves is a crucial step in ensuring the insulation performance and structural stability of the wire harness. The core requirement is to achieve a tight fit between the heat shrink sleeve and the wire harness, while simultaneously ensuring processing efficiency and finished product quality. Currently, the semi-automatic heat shrink sleeve flattening devices used in the industry still suffer from two major technical challenges in practical applications, making it difficult to meet diverse production needs and high-quality processing standards. I. The device lacks versatility and has limited adaptability. Existing semi-automatic heat shrink tubing flattening devices mostly employ a fixed, integrated guide structure. Once the guide ring's inner diameter, shape, and other parameters are formed, they cannot be adjusted or replaced. When dealing with wire harnesses and heat shrink tubing of different specifications—for example, wire harnesses with varying diameters or heat shrink tubing with differences in wall thickness and shrinkage rate—the fixed guide ring cannot match the processing requirements of different sizes. To handle products of various specifications, companies need to purchase complete sets of devices or dedicated guide components of corresponding sizes, significantly increasing equipment procurement costs and workshop storage space. This also necessitates frequent downtime for equipment or component replacement, leading to production interruptions and a significant reduction in processing efficiency. The limitations of the fixed guide structure are particularly pronounced in small-batch, multi-variety wire harness processing scenarios, severely restricting the production line's flexible production capabilities. II. Unstable heat shrink quality, resulting in a low finished product qualification rate. The core quality indicators for heat shrink sleeve flattening processing lie in the uniform shrinkage of the heat shrink sleeve throughout, its tight fit with the wire harness, and the absence of problems such as bubbles, wrinkles, or localized overheating and carbonization. However, existing devices have significant defects in the heating and traction control stages: On the one hand, the traction process between the wire harness and the heat shrink sleeve often relies on manual dragging or simple mechanical traction, making it difficult to accurately control the traction speed. This often results in inconsistent speeds, leading to significant differences in the residence time of different parts of the heat shrink sleeve in the heating area. Some areas are underheated, resulting in insufficient shrinkage, while others are overheated, leading to aging and deformation. On the other hand, the heating components of existing devices mostly use resistance wire direct heating or hot air heating structures, resulting in a significant temperature gradient on the heating surface. Areas near the heating source are too hot, while areas far from the heating source are too cold, causing uneven heating in the circumferential or axial direction of the heat shrink sleeve, further exacerbating the problem of inconsistent shrinkage. These defects directly lead to poor quality stability of the heat-shrinkable finished product, with a pass rate typically below 85%. This not only increases raw material waste and rework costs but may also cause safety hazards in subsequent products due to substandard insulation performance of the heat shrink sleeve.
