Anti-reverse control method for reels

Abstract

The invention discloses an anti-reverse control method for reels; the method comprises the following steps: in an empty reel loading process, equipment automatically loads an empty reel into a reel motor; in positioning and hole finding processes, an automatic reel replacing mechanism of the equipment automatically finds a carrier tape inserting hole on the reel; a detecting device begins to detect the direction of the reel, if the direction is right, the detecting device transmits a low level control signal output by a sensor to a device control center, the equipment continues to operate; if the direction is wrong, the detecting device transmits a high level control signal output by the sensor to the device control center, the equipment automatically removes the reel with the wrong direction and reloads a new empty reel into the reel motor; and the steps of locating and finding holes and detecting the direction of the reel by the detecting device are carried out continuously. According to the anti-reverse control method, a product is prevented from winding reversely relative to the reel after carrying the tape, the unnecessary repetition work is reduced, the control is accurate and the reverse winding of the reel is completely put an end to.

Description

Technical field [0001] The present invention involves semiconductor production technology fields, and specifically involves a roll anti -anti -countermeasure control method in a semiconductor production. Background technique [0002] During the production process of semiconductor devices, in order to prevent damage to the electronic component of the patch and facilitate storage and transportation, the electronic component of the patch is usually placed on the packaging band, and the load rolls of electronic components are put on the packaging roll plate.The work process is this: the device loads an empty rolling plate to the rolling motor, and the automatic replacement of the roll -up mechanism will automatically find the loaded band on the rolling tray.Run, the carrier began to wrap on the roll.At present, there is such a problem in the production process of semiconductor devices: the device is automatically replaced by the roll, but when replacing the rolls, the direction of th...
