position mould 1 drives the head upper bolster 6 of correspondence to rise，Vacuum generator work simultaneously，Upper weldering bag pipe mold group 10 rises crush seal adhesive tape 801，The air sealed in space is constantly discharged in air be formed vacuum by vacuum generator，When the vacuum degree measurement switch that vacuum generator is subsidiary，Detect when vacuum reaches setting value，Vacuum generator power-off does not works，Upper weldering bag pipe mold group 10 is close to connect on substrate 805 securely，If vacuum degree measurement switchs，Detect that vacuum is less than setting，Vacuum generator is energized again work；Linear cam 902 is under cover half cylinder 901 promotes, linearly guide rail 903 moves, linear cam 902 driving rolls 904 drives lower weldering bag pipe mold group 11 down to move, after roller 902 is rolled to linear cam 902 front end (away from a cylinder) transverse plane, the decline of lower weldering bag pipe mold group 11 puts in place, cover half cylinder 901 stops, and again realizes the lower locking welding bag pipe mold group 11；nullAdditionally，Diaphragm is delivered to weld lower in bag head station die 2 weldering on the corresponding position of bag head set of molds 13 together with the conduit welded together，After arriving relevant position，The cylinder 5 of weldering bag head station die 2 drives the head upper bolster 6 of correspondence to decline，Corresponding vacuum mould absorption device 8 makes weldering bag head set of molds 12 drag connection substrate 805 away from，Corresponding linear cam lifting fixed die mechanism 9 drives lower weldering bag head set of molds 13 to rise，Complete weldering bag head set of molds 12 to connect with corresponding lower weldering bag head set of molds 13，Now upper weldering bag head set of molds 12 connects high frequency，Lower weldering bag head set of molds 13 ground connection，On being in、Between lower module under the cooperation of contact rod 16-3，Make、The head of lower diaphragm completes welding，This is second step，After second step completes，The cylinder 5 of weldering bag head station die 2 drives the head upper bolster 6 of correspondence to rise，Corresponding vacuum mould absorption device 8 sucks weldering bag head set of molds 12，Corresponding linear cam lifting fixed die mechanism 9 drives lower weldering bag head set of molds 13 to decline，Diaphragm is delivered to weld lower in bag limit station die 3 weldering on the corresponding welding position of set of molds 15, bag limit together with the conduit welded together，Now，The cylinder 5 of weldering bag limit station die 3 drives the head upper bolster 6 of correspondence to decline，Vacuum mould absorption device 8 and linear cam lifting fixed die mechanism 9 play and first equally、The effect that two steps are same，High frequency is connect in upper weldering bag limit set of molds 14、Lower weldering bag limit set of molds 15 ground connection、In the case of in accessory positioning device 16, contact rod 16-3 expels welding position，Carry out the welding of two diaphragm remainders.Through the welding of above three steps, blood taking bag molding.
This present invention, avoiding the conversion of bond pattern compared to existing technology, makes welding performance more stable, decreases non-cutting time.
The examples of implementation of the above are only the preferred embodiments of the invention, not limit the practical range of the present invention with this, therefore the change that all shapes according to the present invention, principle are made, all should contain within the scope of the present invention.
