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; ifthe 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 invention relates to the technical field of semiconductor production, in particular to a reel anti-reverse control method in semiconductor production. Background technique [0002] In the production process of semiconductor devices, in order to prevent damage to SMD electronic components and facilitate storage and transportation, SMD electronic components are usually placed on the packaging carrier tape, and then the carrier tape with electronic components is rolled onto the packaging reel , its working process is as follows: the equipment loads an empty reel on the reel motor, the automatic reel changing mechanism will automatically find the carrier tape insertion hole on the reel, when the carrier tape insertion hole is found, the device continues Running, the carrier tape starts to wind on the reel. At present, there is such a problem in the production process of semiconductor devices: the equipment automatically changes the reel, but when chan...
