To achieve the accuracy of part installation is demanding during the assembly of safety fine catheter for blood collection needle. An example is the positioning of the cutting edge of a needle. Traditional manual assembly processes often fail to minimize the defect rate.Against this bottleneck in the industry, Maider has independently developed an automatic assembly line for fine catheter for blood collection needle, an industry-leading intelligent manufacturing system for medical consumables. Deviating from traditional manufacturing that relies on manual assembly, this system realizes automatic adhesion and assembly between fine catheters, blood collection needle parts, hubs, and anti-bacterial caps. This approach effectively overcomes challenges in terms of complicated parts/processes, low efficiency due to manual assembly, high risks of contamination, and unstable product quality, thus facilitating the efficient and reliable assembly of final products of fine catheter for blood collection needle and helping large-scale medical enterprises achieve digitalized manufacturing, which minimizes their order delivery time and production costs.
