Circuit board conveying fixed rail with automatically-adjusted width

Abstract

The invention discloses a circuit board conveying fixed rail with automatically-adjusted width. The circuit board conveying fixed rail comprises a fixed edge forming board conveying rail, a linear guide rail, a movable edge rail installation seat, a movable edge forming board conveying rail, a back pressing board speed-reducing stepping motor, a front pressing board speed-reducing stepping motor, a board conveying belt stepping motor and a width adjusting stepping motor. The inner side of the fixed edge forming board conveying rail and the inner side of the movable edge forming board conveying rail are respectively and sequentially provided with a board conveying driving pulley, a board conveying driven pulley, a board conveying driven pulley and a board conveying driving pulley. The circuit board conveying fixed rail with the automatically-adjusted width can achieve the functions of circuit board conveying, clamping and positioning and automatic width adjusting of circuit boards with different specifications, and therefore automation level can be greatly improved. The stepping motors are used for all executive components, and therefore synchronism can be improved, and precise positioning can be guaranteed; and in addition, the whole device is simple in structure, high in reliability and capable of completely replacing an existing board conveying device with pneumatic motors and speed reducing motors as main executive components.

Description

technical field [0001] The invention relates to the technical field of electronic manufacturing and processing equipment, and specifically refers to an automatic placement machine, an automatic insertion machine or other on-line automatic detection and assembly machines used in the assembly and production of electronic parts for feeding boards and fixing circuit board tracks. [0002] Background technique [0003] With the rapid development of the electronics industry, the improvement of manufacturing process requirements and the difficulty of employing front-line workers, the automation of electronic manufacturing and processing is getting higher and higher.
