A high-end CNC machine tool manufacturer needs to equip its five axis machining center with a teaching pendant (for manual operation and parameter setting), and integrate the power, signal, and gas pipeline of the robot arm through a pipeline package. Previously, the manufacturer adopted a combination scheme of "teaching tool harness+third-party pipeline package", which had problems such as poor compatibility between the harness and pipeline package (6 hours for single equipment installation), insufficient protection performance of the pipeline package (line wear is prone to occur during high-speed operation of the machining center, affecting equipment accuracy), and so on. In 2021, the manufacturer sought integrated wiring harness and pipeline package solutions, and Lianjie Technology participated in the cooperation with related services.

Product adaptation and solutions

Lianjie Technology provides integrated customized services for teaching device wiring harnesses and industrial robot pipeline packages, as follows:

1. Teaching pendant wiring harness: Based on the structure and multi signal transmission requirements of the teaching pendant (including data, power, and touch signals), thin and highly flexible wires (wire diameter 0.3mm) are used to reduce the space occupied by the wiring harness; The connector adopts a miniature waterproof connector (IP67 protection level) to prevent the infiltration of coolant from the machining center, which helps to ensure the stable operation of the teaching pendant.

1. Industrial robot pipeline package: It adopts multi-layer composite casing (inner layer is wear-resistant nylon, outer layer is flame-retardant polyurethane), which has the characteristics of tensile resistance, bending resistance, and cutting fluid corrosion resistance; Internally, partition and isolate according to the type of circuit (power line, signal line, air pipe) to reduce signal interference and air pipe leakage; At the same time, based on the motion radius of the machining center robot arm, optimize the length and bending radius of the pipeline package to ensure smooth operation.

1. Integrated service: Provide on-site installation guidance, standardize the installation process of wire harnesses and pipeline packages, and promise 24-hour technical response. If any problems occur, on-site repairs will be carried out within 48 hours.

Project Results

After the implementation of this plan, it will bring the following value to customers:

·Installation efficiency: The installation time for a single equipment harness and pipeline package has been reduced from 6 hours to 2 hours, and the assembly efficiency of the production line has been improved;

·Equipment reliability: The number of pipeline package wear failures has decreased from an average of 12 per year to 1, the stability of machining accuracy has been improved, and the product qualification rate has increased from 98.5% to 99.8%;

·Market feedback: The manufacturer's five axis machining center has increased its market share from 15% to 22% due to its stability performance, and has listed Lianjie Technology as a component supplier.
