Embodiment Construction
[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0031] like figure 2 As shown, the glass cloth tension adjustment system described in this embodiment is installed on the adhesive sheet production device to adjust the tension of the glass cloth in operation to overcome the local tension caused by the tension change of the glass cloth during operation. deformation defects.
[0032] The glass cloth tension adjustment system includes: a tension detection device, a judgment device and an adjustment device.
[0033] Wherein, the tension detection device is used to detect the tension values of the two ends and the middle of the glass cloth along its width direction. In this embodiment, the tension detection device adopts a bearing-type tension sensor 1 , and the tension values at the left and right ends and the middle of the glass cloth can be ob...

The invention discloses a glass cloth tension adjustment system which comprises a tension detection device, a judgment device and an adjustment device. The tension detection device is used for detecting tension values of the two end portions and the middle, in the width direction of glass cloth, of the glass cloth, the judgment device is used for comparing the detected tension values to judge the tension change position, and the adjustment device is used for carrying out adjustment on the tension of the tension change position of the glass cloth. The invention further discloses a glass cloth tension adjustment method which includes the following steps: detecting the tension values of the two end portions and the middle, in the width direction of the glass cloth, of the glass cloth, judging the tension change position by comparing the detected tension values, if the tension change position is located on the two end portions of the glass cloth, driving the end portion of an adjustment roller to perform lifting movement to adjustment the height difference of the two end portions of the adjustment roller to enable the tension in the weft direction of the glass cloth to be coincident, if the tension change position is located in the middle of the glass cloth, calibrating coordinates of the tension change position through a displacement sensor, and enabling a driving device to drive the adjustment roller to move towards the tension change position according to the coordinates to enable the tension in the weft direction of the glass cloth to be coincident.
Description
technical field [0001] The invention relates to the technical field of circuit boards, in particular to a glass cloth tension adjustment system and method. Background technique [0002] Circuit boards include printed circuit boards (PCBs) and flexible printed circuit boards (FPCBs), which are widely used as essential components for circuit interconnection in most electronic products. The circuit board is mainly composed of a conductive printed circuit and an insulating substrate. The insulating substrate is another important component of the circuit board, which includes a bonding sheet made of reinforced material glass cloth impregnated with resin. [0003] The prior art discloses a bonding sheet production device, figure 1 The structure of this adhesive sheet production apparatus is shown. like figure 1 As shown, the adhesive sheet production device includes a glass fiber cloth unwinding unit 100 , a prepreg unit 200 , a main impregnation unit 300 , a baking unit 400 a...
