Automatic splicing device
View Patent ↗A control device, that based on number one and number two component presence signals, respectively calculates number one and number two cutting points of number one and number two tapes from predetermined pitch of number one and number two cavities, and number one and number two distances between number one and number two detection positions and number one and number two cutting positions. By this, cutting points can be specified even when tapes have different pitches between cavities, and the tapes can be spliced reliably.
1. An automatic splicing device which connects number one tape and number two tape provided with cavities for storing components and indexing holes at fixed intervals using splicing tape, comprising:
number one and number two cutting devices for respectively cutting at number one and number two cutting positions respective unnecessary sections at a tail end of the number one tape and a leading end of the number two tape;
number one and number two indexing devices for conveying the number one and number two tapes respectively along number one and number two conveyance paths and positioning number one and number two cutting points of the number one and number two tapes in order at the number and number two cutting positions and a splicing position;
number one and number two detection devices for detecting respectively number one and number two cavities of the number one and number two tapes conveyed along the number one and number two conveyance paths, and number one and number two components stored in the number one and number two cavities, at number one and number two detection positions provided respectively in the number one and number two conveyance paths;
a control device for controlling each operation of number one and number two tape indexing devices, the number one and number two cutting devices and a joining device;
wherein the control device has:
a pitch calculating means for calculating a predetermined pitch between the number one and number two cavities based on at least one of the number one and number two cavities detected by at least one of the number one and number two detection devices;
a number one and number two cutting point calculating device for calculating respectively the number one and number two cutting points of the number one and number two tapes from a number one distance between the number one detection position and the number one cutting position, and a number two distance between the number two detection position and the number two cutting position, and the predetermined pitch calculated by the pitch calculating means, based on a number one and number two component presence signal output after the number one and number two detections devices detect a switch from the number one and number two cavities without the number one and number two components to the number one and number two cavities with the number one and number two components; and
a number one and number two cutting position deciding means which control the number one and number two tape indexing devices and move the number one and number two tapes the number one and number two distances after the number one and number two component presence signal is output to respectively decide conveyance positions of the number one and number two cutting points at the number one and number two cutting positions.
2. The automatic splicing device according to claim 1 ,
wherein the control device uses a number one and number two splicing positioning means wherein, when the number one and number two cutting points positioned at the number one and number two cutting positions are cut by the number one and number two cutting devices, the number one and number two tape indexing devices are controlled so that the number one and number two cutting points are moved number three and number four distances between the number one and number two cutting points and the splicing position so that the number one and the number two cutting points are positioned at the splicing position.
3. An automatic splicing device according to claim 2 ,
wherein the number one and number two cuttings devices comprise: number one and number two cutters which cut the number one and number two cutting points positioned at the number one and number two cutting positions of the number one and number two tapes and which are attached to be movable up and down; and
number one and number two pressing members provided adjacent to the number one and number two cutters so that they can move up and down, which press and fix an area around the number one and number two cutting points of the number one and number two tapes respectively positioned at the number one and number two cutting positions.
4. An automatic splicing device according to claim 1 ,
wherein the number one and number two cuttings devices comprise: number one and number two cutters which cut the number one and number two cutting points positioned at the number one and number two cutting positions of the number one and number two tapes and which are attached to be movable up and down; and
number one and number two pressing members provided adjacent to the number one and number two cutters so that they can move up and down, which press and fix an area around the number one and number two cutting points of the number one and number two tapes respectively positioned at the number one and number two cutting positions.
