Description

Technical Field

[0001] The present invention relates to the technical field of medical product processing, and specifically to a circular production line and production method for nerve surgery pads. Background Art

[0002] As an important medical consumable, the production quality of nerve surgery pads is directly related to the aseptic barrier performance and operation reliability during surgery. Traditional production processes mostly adopt segmented assembly line operations, which have prominent problems such as poor process connection, excessive manual intervention, and low production efficiency. For example: In the prior art, core processes such as non-woven fabric substrate laying, developer barium wire positioning, and reinforced chemical fiber welding need to be transferred between different workstations. The material positioning accuracy is significantly affected by mechanical cumulative errors, resulting in about 3%-5% of products having layer offset exceeding the medical standard.

[0003] In the barium wire cutting link, mechanical clamping feeding is generally used, resulting in length deviation (more than ±2mm) caused by wire rebound; the flexible chemical fiber wire material is prone to electrostatic adsorption in the traditional feeding system, causing the feeding path deviation rate to reach more than 12%, seriously affecting the welding quality.

[0004] The independent layout of each functional module occupies a large space. The conversion between workstations requires a complex mechanical transmission mechanism, and the equipment failure rate remains above 0.8 times per thousand hours, and the maintenance cost accounts for 15%-20% of the total production cost.

[0005] In response to the above technical bottlenecks, the industry has tried to improve using a linear assembly line. However, due to the physical limitations of the linear layout, there are still inherent defects such as difficult workstation expansion and poor beat synchronization. Especially when dealing with the composite welding of barium wire and high-density chemical fiber wire, traditional equipment is difficult to achieve precise alignment and synchronous fixation of the two heterogeneous materials, resulting in the product qualification rate remaining between 85%-88% for a long time.
