AI Technical Summary

Technical Problem

Existing mechanical tension control devices are difficult to achieve precise and continuous tension control during the continuous electroplating process of terminals, resulting in uneven electroplating layer thickness and low production efficiency.

Method used

The guide rollers and tension adjusting rollers are arranged alternately. The rotational resistance of the tension adjusting rollers is controlled by adjusting the locking force of the clamp structure. The locking force is infinitely adjustable by using the adjusting screw and compression spring. Combined with wear-resistant bushings and baffle limiters, tension stability is ensured.

Benefits of technology

It achieves continuous and stable control of the tension of the terminal strip, avoids tension fluctuations and roller wear, and improves electroplating quality and production efficiency.

Abstract

A terminal strip tension control device includes a mounting plate on which at least two guide rollers and at least one tension adjusting roller are rotatably connected, arranged alternately along the terminal strip conveying direction. The tension adjusting roller's shaft is equipped with a clamping structure with adjustable locking force. By adjusting the clamping force on the shaft, the rotational resistance is controlled, thereby precisely adjusting the terminal strip tension. A wear-resistant bushing is fitted onto the shaft surface to improve its lifespan. Baffles are provided on both sides of the guide rollers and the tension adjusting roller, and a limit wheel is added next to the input-side guide roller to prevent the terminal strip from derailing. A feeding roller at the front end of the mounting plate supports the terminal strip, reducing wear. This device achieves stable tension adjustment through mechanical decoupling design, has a simple and reliable structure, and is suitable for high-precision tension control of terminal strips.
