conveyor belt

Abstract

The conveyor belt of the present invention comprises: a front fixed track; a rear fixed track parallel to the above-mentioned front fixed track; a front moving track between the above-mentioned front fixed track and the above-mentioned rear fixed track and parallel to the above-mentioned front fixed track; a rear moving track , between the above-mentioned front moving rail and the above-mentioned rear fixed rail, and move in parallel with respect to the above-mentioned rear fixed rail; the detecting part detects the positions of the above-mentioned front moving rail and the above-mentioned rear moving rail; the control part detects the above-mentioned The positions of the front moving track and the above-mentioned rear moving track, select the starting positions of the above-mentioned front moving track and the above-mentioned rear moving track, and move the above-mentioned front moving track and the above-mentioned rear moving track to the selected starting position.

Description

technical field [0001] The invention relates to a conveyor belt, in particular to a two-lane conveyor belt with adjustable lane width. Background technique [0002] Generally speaking, a component mounting device is a device that mounts various electronic products on a printed circuit board, and the printed circuit board is transferred to the working area (workzone) in the component mounting device through a conveyor belt device, and in the working area, various components Mounted at the respective positions on the transferred printed circuit board. [0003] Recently, the conveyor belt has been developed as follows: In order to improve productivity, two printed circuit boards are sent into the work area at the same time, and the two-lane method is used to send out the components mounted on the two printed circuit boards at the same time. Lane width, thus widely used with various sizes of printed circuit boards. [0004] A conveyor belt that can adjust the width of a double...

AI Technical Summary

Problems solved by technology

[0005] However, when using a two-lane conveyor belt, there is no function to detect the positions of the two movable rails when the conveyor is initially started or restarted due to an error, and the operator needs to rearrange the two movable rails manually.

[0006] In addition, when restarting the conveyor belt, even if the function of moving the two movable rails to the initial position is included, because there is no function of detecting the positions of the two movable rails, it will be difficult to move the two movable rails to the initial position. In the process of moving to the original position, the two tracks collide with each other or the error occurs again during the movement to the starting position

[0007] In addition, usually the starting position of the two-lane conveyor belt is set at the center of the two movable rails, but in order to transfer large printed circuit boards, one lane of the two-lane is adjusted to a wide width, and the other lane is minimized. In the case of a single lane, it is more troublesome to move back to the two tracks at the starting position
