Working principle of tape and reel machine: after the tape braiding and packaging electromechanical and gas are connected, if it is hot packaging, let the knife rise to the appropriate temperature and adjust the tape carrier and air pressure. Put the SMD components into the carrier belt with manual or automatic feeding equipment, and the motor rotates to pull the cover belt forming carrier tape to the packaging position. In this position, the cover belt is on the top and the carrier belt is on the bottom. After heating, two blades are pressed on the cover belt and the carrier belt to seal the SMD component port on the carrier belt, so as to achieve the purpose of SMD component packaging. Then the receiving tray rolls up the encapsulated carrier tape.
The tape and reel machine can provide unified direction, test product polarity, appearance inspection, laser marking and other functions according to the production needs of customers.
Some tape and reel machines are not hot sealed, but cold sealed. The cold sealing of the stomach is that the cover belt and the carrier belt can be stuck together without heating. At this time, the cover belt used should be sticky. Before packaging, the carrier belt generally goes through two sensors, one for counting and the other for material control. Material control is to detect whether there are missing components in the carrier belt. If a leakage is detected, the motor of the braiding machine will stop immediately and the cutter head will also be generated to the upper position. The counting sensor generally uses optical fiber and also requires fast reaction speed, so that the counting will not be missed. The counting sensor can count the side holes of the carrier belt or the formed grooves. The number of side holes must be converted back to be the correct number of SMD.
