ShinMaywa Develops New Automatic Wire Terminating Machine Model for Both-ends Crimping

- Global model with excellent expandability for the automotive market (also meets Europe's CE specifications) -

ShinMaywa Industries, Ltd. (Headquarters: Takarazuka, Hyogo, Japan, President: & CEO: Tatsuyuki Isogawa) today announced the development of a new automatic wire terminating machine "TRD701," a both-ends crimping machine that measures, cuts, and crimps wires used in wire harnesses. ShinMaywa will exhibit the new model at productronica 2019, being held in Munich, Germany from November 12-15, 2019.

Recently, in the automotive market, as technical development has accelerated for supporting the move toward CASE (connected, autonomous driving, sharing, and electrification), the electronic-circuit-based control instruments for sensors and cameras needed in active safety functions are becoming standard features, in addition to the electrification of vehicles themselves. As a result, a large number of precision electronic instruments are being installed and the number of wire harnesses used per vehicle is increasing, causing the total demand for wire harnesses to expand globally.
Against this background, the users of automatic wire terminating machines are demanding further productivity improvement and higher processing quality.

The recently developed TRD701 both-ends crimping machine has dramatically improved wire-processing capability and quality, and has also achieved a shorter setup time, based on the concepts of higher performance (improvement in processing capacity), better quality (improved processing quality), and less downtime (improved productivity by shortening the setup time).


TRD701 both-ends crimping machine

In terms of processing capacity, weight reduction in the rotating unit and platform optimization shortened the tact time, achieving a maximum processing capability of 4,300 pieces/hour (an increase of approximately 30% over the company's current model) when crimping 1,000 mm at both ends.

In terms of processing quality, the installation of various new sensors, such as a high-precision terminal crimping monitor (HTCM), a core touch detector (CTD), and a silhouette vision sensor (SVS), has improved both quality and reliability. Finally, productivity has been improved and the setup time shortened through the adoption of various devices, such as an automatic wire changer, a servo-controlled wire straightener, a two-stage sorting tray, dual cutter heads, and a nozzle-less wire clamp.

ShinMaywa will continue to seek higher productivity and better after-sales services by developing new technologies and improving the quality of its machines to help customers improve their productivity.

1. Features of the new TRD701 both-ends crimping machine

(1) High Performance (Improvement in processing capability)

Tact time reduction through measures such as weight reduction in the rotating unit has achieved high processing capability.

  • Maximum processing capability:
    4,300 pieces/hour when crimping 1,000 mm at both ends (an increase of approximately 30% over the company's current model)
    (5,200 pieces/hour when crimping 100 mm at both ends (an increase of approximately 37% over the company's current model)

(2) Better Quality (New sensors for improving processing quality)

  • High-precision terminal crimping monitor (HTCM)
    Detects core wire cut-off of 10% or more and sorts out even minute failures, providing a high level of judgment performance in terminal crimping.
  • Core Touch Detector (CTD)
    Detects contact between the stripping blade and the core wire, preventing the core wire from being cut.
  • Silhouette Vision Sensor (SVS)
    Can detect stripping, seal insertion, and semi-stripping defects during processing by using the silhouettes of the wire and seal.

(3) Less downtime (Various types of new functions to shorten the setup time)

  • Automatic Wire Changer
    During processing, the wire from the next lot can be set, significantly shortening the wire-swapping time (shortening the standard manual operation time from 40 seconds to 15 seconds).
  • Servo-Controlled Wire Straightener
    Uses a servo motor to control the Wire Straightener which eliminates kinks in the wire, significantly shortening the setup time.
  • Two-stage sorting tray
    Separates good wires from defective wires and discharges only the good wires into the bottom stage, minimizing machine downtime for removing wires and improving the ease of setup.
  • Dual cutter heads
    The Cutter head is equipped with two types of stripping blades, making it possible to handle different wire types and sizes without a blade change.
  • Nozzle-less wire clamp
    Eliminates the need to change the nozzle according to the wire size, significantly shortening the setup time.
