A well-known electronic manufacturer faces two core problems: first, the installation space of equipment is extremely limited, and there is a protection blind spot in traditional safety devices; Second, when multiple sets of safety light curtains are densely distributed, they are easy to interfere with each other, leading to false alarm or failure.
In view of this special working condition, we innovatively adopted EFP series type 4 safety light curtain solution without blind area. The scheme has three technical breakthroughs:
Firstly, through the three-dimensional arrangement of three sets of safety light curtains, the protection without dead angle in vertical and horizontal directions is realized;
Secondly, with special optical design, the anti-light interference ability is improved by 300%;
Third, the double-loop safety output design ensures that the system reliability reaches the highest safety level of PL e. The implementation effect is remarkable: the elimination rate of potential safety hazards reaches 100%, and the false alarm rate is controlled below 0.01%.
It is particularly worth mentioning that the compact design of EFP series light curtain (only 60% of the volume of traditional products) perfectly adapts to the narrow space of automatic screw machine, and its anti-electromagnetic interference characteristics ensure that the production efficiency is not affected. This scheme has been successfully applied to many 3C electronic production lines, and it has become a model of high-density small space safety protection.
Customer feedback shows that the industrial accidents are reduced to zero, the comprehensive efficiency of equipment is improved by 15%, and the annual maintenance cost is reduced by 200,000 yuan. This innovative scheme not only solves the limitations of traditional safety equipment, but also sets a new benchmark for the safety production of 3C electronics industry.
