Single-sided tape tension control mechanism

Abstract

The invention discloses a single-sided tape tension control mechanism consisting of a horizontal panel, a vertical mainboard connected with the horizontal panel, a motor fixing plate, a driving motor, two synchronous wheels, a synchronous belt, a tape releasing fixed shaft and a single-sided tape fixed disk connected with the tape releasing fixed shaft, wherein the two synchronous wheels and the synchronous belt are connected with the motor in a driving way; the two synchronous wheels are respectively provided with a silica gel idler wheel and a polyurethane idler wheel; the other side of the vertical mainboard is provided with a lifting slide bar fixing plate on which lifting slide bars are arranged; the bar body of one of the lifting slide bars is respectively provided with an approach switch; the bar bodies of the two lifting slide bars are respectively provided with a linear motion bearing; the bearing is provided with a slide block; the bottom ends of the two lifting slide bars are connected through the lifting slide bar fixing plate; and the end of the lifting slide bar fixing plate is provided with a tape fixing bar. By using the single-sided tape tension control mechanism, the problem of nonuniform tension can be solved thoroughly so that the stability of the tension of copper foil is enhanced.

Description

technical field [0001] The invention relates to a copper foil spot welding machine, in particular to a single-sided adhesive tape tension control mechanism in the copper foil spot welding machine. Background technique [0002] At present, due to the different viscosities of the single-sided tape used in the existing domestic copper foil spot welding machines (the viscosities of the outer layer, the middle layer, and the inner layer of the tape are quite different), sometimes the tension is unstable when the stepping motor pulls the copper foil. The elongation is sometimes shortened, resulting in inconsistent lengths of the copper foil after cutting, and the position of the solder joint and the cutting edge is long and short, which brings inconvenience to subsequent production and increases the defective rate. Contents of the invention [0003] The object of the present invention is to provide a single-sided adhesive tape tension control mechanism, which can keep the output...

Problems solved by technology

[0002] At present, due to the different viscosities of the single-sided tape used in the existing domestic copper foil spot welding machines (the viscosities of the outer layer, the middle layer, and the inner layer of the tape are quite different), sometimes the tension is unstable when the stepper motor pulls the copper foil. Sometimes it is stretched and shortened, resulting in inconsistent lengths of copper foil after cutting, and the position of solder joints and cutting edges is long and short, which brings inconvenience to subsequent production and increases the defect rate.
