Working principle of taping machine
Working principle of tape and reel machine: after the taping 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. Use manual or automatic feeding equipment to put SMD components into the carrier belt, the motor rotates to form the cover belt, and the carrier belt is pulled to the packaging position. In this position, the cover tape is on and the carrier tape is under. After heating, two blades are pressed on the cover tape and the carrier tape, so that the cover belt seals the SMD component port on the carrier tape, so as to achieve the purpose of SMD component packaging. Then the receiving tray rolls the encapsulated carrier tape.
The taping 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 means 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 passes 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 leakage is detected, the motor of the tape braiding machine will stop immediately and the cutter head will be generated to the upper position at the same time. The counting sensor generally uses optical fiber, and it is also used, and the reaction speed is required to be fast, 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.
The taping machine has high taping speed. With testing function, equipped with corresponding tester, tape braiding function can quickly test the capacity value and resistance value of the chip, and sort the good and bad products; The tape and reel machine adopts PLC as the core control; The display screen has unique design. The LCD displays the order and simulates the state of each control point. It can easily set and modify various parameter values, monitor various working states and their braiding speed. The braiding machine works stably and has reliable performance.
