Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an end-to-end connecting device for electronic component tape wound around a reel.

Conventional technology Generally, in order to supply electronic components to an automatic mounting process, the electronic components are held at predetermined intervals on the tape surface and fed by pitch feeding by being fed from a thread, and the electronic components are then picked up from the tape surface using a suction head. Electronic component tapes are used that are individually picked out and mounted on the surface of a printed circuit board on which a conductive pattern is formed.

Conventionally, this electronic component tape is wound on a reel and stocked one by one, and it is loaded into the tape feeder of an automatic loading machine and fed in pitch, and when the tape ends being fed. In response to an alarm display or the like, the worker can continue the work by switching to another electronic component chain.

Problems to be Solved by the Invention However, since this electronic component tape normally holds about 4,000 electronic components every 41 pitches and is fed intermittently at a high speed of 0.2 seconds, it takes about I have to change the hook to another one after about 20 minutes. As a result, it is not only necessary to assign a full-time worker to each machine and to frequently change parts, but also to temporarily stop the automatic mounting machine each time, resulting in lost time. .

Means for Solving the Problems In the end-to-end connection device for electronic component tapes according to the present invention, two electronic component tapes wound around each reel, the tape to be currently sent out and the tape to be sent out next, are connected to each other. A tape holding member is provided on one side of a tape conveyance path through which one of the electronic component tapes is sent out from the reel stand, and is movable forward and backward, and on the opposite side across the tape conveyance path. A tape receiving member is arranged to hold another electronic component tape on the starting end side, with the adhesive layer attached to the starting end facing the tape transport path, and the terminal end of the electronic component tape is further placed along the tape transport path. A cutter device for cutting and a detector for detecting the terminal end of the electronic component tape are arranged, and in response to the detection of the terminal end of the electronic component tape by the detector, the tape pressing member and the tape receiving member cut the tape. The terminals are bonded together by pressure, and the terminal end of the electronic component tape can be cut using a cutter.

Function: In this end-to-end connection device for electronic component tape, when the detector detects the terminal end of the electronic component tape, the tape pressing member moves forward in response to the command and presses the terminal end of the tape against the tape receiving member. As a result of this pressure welding, it is possible to bond the electronic component tape with another electronic component tape whose starting end is held in advance by a tape receiving member using the adhesive layer facing the tape conveyance path, and the cutter reels the terminal end of the electronic component tape. By separating the tape from the machine, the operator can feed the tape continuously without stopping the machine by simply loading the next electronic component tape as needed.

Embodiments will now be described with reference to the accompanying drawings.

The end-to-end connection device for electronic component tape shown in the attached drawings is as follows:
It is installed in the mechanism part that pitches the electronic component tape in order to mount the electronic components on the circuit board using the suction head of the automatic mounting machine.

Apertures 17, 17, . . . are provided at predetermined intervals for fitting into the recesses 12, 12, . Furthermore, as shown in FIG. 3, a sensing tape 18 made of a material that does not transmit light is attached to the terminal end of the tape over a predetermined number of electronic component arrangement positions from the terminal end.

When this electronic component series tape T is fed at predetermined pitches through the feed holes 14, 14, etc., as shown in FIG. By peeling off the adhesive layer 16, the adhesive layer 16 is held by the tape receiving member 5 toward the tape transport path X.

In this state, when the electronic component series tape T1, which is currently being pitch-fed, approaches the end, the detector 9 detects the sensing tape 18 and corresponds to the tape portion at the rear position that does not hold the electronic components 10, 10... The tape pressing member 3 and the upper blade 6 are operated.

This operation is performed at the end of the electronic component tape TI with respect to the next electronic component tape T2 whose adhesive layer 16 faces the tape transport path X and whose starting end is held by the tape receiving member 5, as shown in FIG. The two sides are brought into pressure contact by the forward movement of the tape pressing member 3 as shown in the figure. In addition to bonding each end with the adhesive layer 16 by the pressure welding, the opening 17 on the starting end side,
By fitting the concave portions 12, 12, . Immediately after this pressure welding, the upper blade 6 also moves forward as shown in FIG. ,
Thereafter, the electronic component tape T2 is continuously fed in pitch. Immediately after the operation is completed, the tape pressing member 3 and the upper blade 6 move backward and wait until receiving the next command. In addition, the reel stand 1 has a support shaft 2 as shown in FIG.
The electronic component tape T2 is sent out along the tape transport path X by being reversed around the center, and the position is changed to exchange the empty reel of the electronic component tape TI with the next reel of the electronic component tape TI. Can be done.

This end-to-end connection device for electronic component tape has multiple rows of tape transport paths X as shown in FIG. 6.7.
