[0002] Gluing is an essential process for backlight modules. The rubber strip comes in the form of a rectangular diaphragm, and several slender rubber strips are arranged in parallel at intervals on one diaphragm. Before gluing, the rubber strip needs to be cut first, and then the cut rubber strip is transferred to the next processing station. Currently, the cutting process has been automated, that is, a specific cutting device is used to cut the whole diaphragm.

[0003] As is well known, before cutting the rubber strip, it is necessary to rectify and fix the diaphragm to be cut. In the specific operation process, it is necessary to first use a specific clamping device to clamp the diaphragm to be cut, and then the rectifying device rectifies and corrects the clamped diaphragm on both sides. This method will cause the clamped end of the clamping device to be relatively fixed to the diaphragm during rectification, resulting in pulling on the diaphragm and the phenomenon of diaphragm wrinkles, causing a high defective rate of diaphragm cutting.
