Belt converyer for mounting componenet

Abstract

The present invention provides a tape feeder for chip mounters. The tape feeder is constructed so that front and rear locators are restrained by a restraint slot of a cam slider moving horizontally, and bearings of the front and rear locators alternatively execute vertical and horizontal movements while sliding along the restraint slot by a reciprocating motion of a cam slider, thus repeatedly moving a carrier tape backward while locking the carrier tape and moving the carrier tape forward while releasing the carrier tape, therefore allowing the carrier tape to be fed precisely. The tape feeder allows the carrier tape to be fed precisely, and prevents chips from being turned over and removed from the carrier tape when a vinyl cover is discharged, thus minimizing a malfunction of the chip mounter during an operation of the chips and thereby maximizing operational reliability. Further, the tape feeder allows the number of elements to be reduced, in addition to achieving a slim construction. Thus, the number of tape feeders mounted to the chip mounter can be increased.

Description

technical field [0001] The present invention relates to a tape feeder for a component mounting machine, which provides precise conveyance of a conveyor belt containing semiconductor chips through a linear motion mechanism, and prevents the contained chips from being It can effectively reduce the misoperation of picking up, maximize the reliability of the device, and realize the simplification of the structure and the simplification of the overall volume. Background technique [0002] In general, the electronic component mounting machine (Chip Mounter) vacuum-adsorbs the electronic components (semiconductor chips) supplied by the conveyor on the suction nozzle of the pick and place (Pick and Place) head, so that it is picked up (Pick-up ), transfer and load onto the substrate. [0003] For the above-mentioned conveyors, various types such as tape conveyors, chip conveyors, and tray conveyors have been disclosed. Among them, a tape conveyor capable of supplying chips at high ...

AI Technical Summary

Problems solved by technology

[0008] Since this kind of belt conveyor adopts the method of dividing the circumference of the sprocket at a fixed interval, the interval transfer by the rotation of the sprocket cannot be performed accurately due to the accumulation of rotation tolerances for a certain period of time. , As a result, there will be a problem that the conveying operation has to be reset, thereby reducing the workability, and there will be defects in defective products due to pick-up errors

[0009] In addition, due to the complexity of the components, the overall volume of the conveyor increases, so the width cannot be reduced, and there is also a defect that the operability and usability are poor due to the limitation of the equipment.
