Detailed Description
For the understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
Referring to fig. 1 and fig. 2, a heating type adhesive film cutting process of the present invention includes the following steps:
providing a bearing jig 1, wherein the bearing jig 1 is used for bearing an external adhesive film piece;
providing a cutting component 3, wherein the cutting component 3 is provided with a movably arranged cutter 4;
providing a heating component 2, heating the cutter 4 of the heating component 2 to enable the cutter 4 to rise to a preset temperature or enabling the temperature of the glue film piece borne by the bearing jig 1 to rise to a preset temperature through the heating bearing jig 1 by the heating component 2, and cutting the glue film piece borne by the bearing jig 1 by the cutter 4 with the rising temperature at normal temperature or cutting the glue film piece borne by the cutter 4 with the rising temperature at normal temperature.
Utilize glued membrane spare to be heated softened characteristic, greatly reduced glues the internal stress of membrane spare, when cutter 4 cuts the glued membrane spare after softening, compare in the cutter 4 of normal atmospheric temperature and directly cut normal atmospheric temperature glued membrane spare, greatly reduced pulls the glued membrane spare that causes because of glued membrane spare internal stress and cuts badly (if glued membrane structure warp or glued membrane colour discolours etc.), promotes the yield that cuts of glued membrane spare.
Cutting assembly 3 sets up the driving piece on bearing tool 1 including the installation, and cutter 4 is connected with the output of driving piece, and according to actual need, cutter 4 can be electric cylinder or cylinder, and cutter 4 is connected with the piston rod of driving piece, and the driving piece is used for driving cutter 4 and bears tool 1 relatively and removes, and the cutter 4 of removal can cut the glued membrane spare that bears tool 1 and bear.
The bearing jig 1 is provided with a die cavity 5 and a guide hole communicated with the die cavity 5, the die cavity 5 is used for accommodating a rubber film piece, and the cutting knife 4 is accommodated in the guide hole in a sliding manner. When the driving piece drives the cutter 4 to move, the cutter 4 is limited and stopped by the inner hole wall of the guide hole, so that the moving direction of the cutter 4 is guided, and the cutter 4 is ensured to move along a correct moving path.
The cutter 4 is provided with a containing blind hole, the heating component 2 is arranged in the containing blind hole, the heating component 2 is connected with a lead, and the lead is communicated with an external power supply. When needs cut the glued membrane spare, the power supplies power for heating element 2 via the wire, and the heat transfer after heating element 2 generates heat is to cutter 4 for the temperature of cutter 4 risees, then cutter 4 conflict after the driving piece drive temperature risees bears the glued membrane spare that tool 1 bore, and the heat transfer of cutter 4 is to gluing the membrane spare, makes the temperature of gluing the membrane spare rise, along with the continuous removal of cutter 4, accomplishes cutting to gluing the membrane spare until cutter 4.
