Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention connects an IC via a lead terminal between a pair of frames.
This invention relates to a method of transporting a frame-equipped electronic component in which electronic component bodies such as the following are arranged and connected at a constant pitch.

<Prior art> In general, electronic components with a frame are transported by using a feed hole formed in the frame, or by directly locking the electronic component body (molded sheet). ing.

<Problem to be solved by the invention> However, such frames are not very strong, and are prone to warping and deformation due to thermal effects from molding etc. and external forces from the pond, leading to transportation troubles. It was the cause of this.

Furthermore, once a transportation problem occurs and the frame is significantly deformed, it becomes unusable for further processing, and many electronic components must be disposed of. In addition, similar problems occur with the method of locking the electronic component body, and there are also problems such as difficulty in pitch feeding accuracy due to molding errors and molding gaps in the mold portion.

In addition, in these conventional methods, since the electronic components with frames are loaded into the same conveying device for each processing step, the frame must be changed several times, increasing the chances of problems with changing the frame. So de-nonoko.

The present invention aims to provide a method for safely and reliably transporting a framed electronic component and for feeding the electronic component in a constant pinch manner.

Means for Solving the Problems> In the present invention, a transport unit including a pair of holding members having linear grooves is prepared in advance, and the outer edge of the frame of the frame-equipped electronic component is inserted into the linear grooves of the transport unit. The transport unit is moved at a predetermined pitch along the entire length of the transport unit.

Function> Since the frame of the electronic component is engaged and held in the linear groove of the transport unit over its entire length, the overall warpage and deformation are corrected and the frame is always maintained in a constant posture. Furthermore, since the entire transport unit is moved to each processing step, the number of times to change the frame of the electronic component is reduced.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a conveyance unit used for carrying out the method of the present invention, FIG. 2 is a longitudinal sectional front view thereof, FIG. 3 is a side view thereof, and FIG. 4 is a front view thereof. Referring to these drawings, the transport unit used to carry out the present invention basically consists of a movable frame 1 and a pair of left and right holding members 2.2. A pair of left and right wheels 3.3 using bearings are provided at the front and rear of the lower part of the movable frame 1, and the movable frame 1 can be moved on the device base 4 as shown in FIG.

The clamping member 2.2 is made of a long flat plate material in the front and back, and is disposed facing each other on the left and right sides in an upright position, and a support shaft 6.6, which is fixed and inserted through the gear members 5, 5 that engage with each other, is movable on each opposing inner surface. It is supported by brackets 7.7 erected at the front and rear of the underframe 1, so that the upper parts of both clamping members 2.2 are moved toward and away from each other. Moreover, both clamping members 2.2
Tension springs 8, 8 are tensioned between both members 2.2.
are urged to rotate in a direction in which the brackets 7.7 approach each other, and the limit of rotation of the bracket 7.7 in contact with both left and right shoulder portions is restricted. Further, the end of one of the support shafts 6 protrudes from the bracket 7, and a lever 9 is attached thereto, and when the lever is operated from the outside, both clamping members 2°2 are swung open against the spring 8.8. I am now able to do some things.

A V-shaped straight groove 10.10 is formed on the inner surface of the upper end of the both-side holding member 2.2 over the entire length of the front and back, and the left and right frames 12.1 of the frame-equipped electronic component II are formed.
The outer edge of 2 can be inserted and held over the entire length.

Also, a movable frame! A group of guide rows 914 made of bearings are provided on both left and right sides of the electronic component main body 13 at the same pitch as the arrangement pitch of the electronic component main body 13 . This guide roller 14 is
As shown in FIG. 2, it acts on a guide rail 15 provided on the device base 4, and guides the movable frame 1 along the guide rail 15.

Further, between the guide rails 15 and 15, a conveyor chain 16 serving as a driving means for moving the movable underframe l is arranged so as to rotate in a circular manner, and a psono wheel 17 attached to this chain 16 moves the rear of the underframe. It is configured to abut and lock the ends and press and move.

As shown in FIG. 4, a stopper 18 is provided at the end of the conveyance path or at various treatment process parts installed in the middle thereof, and the stopper 18 is positioned to move in and out from the guide rail 15 side. By engaging the V-shaped end of the movable frame 1 with the guide roller 14, the movable frame 1 can be positioned and stopped at regular pitches.

In the present invention, a transport unit having the above configuration is prepared in advance, and the lever 9 of the transport unit is operated to open both the clamping members 2, 2 against the springs 8.8.
Electronic component 1 in the straight groove 10.10! Both frames 12
．． The outer edge of 12 is engaged and held over its entire length.

Next, the conveyance chain I6 serving as a driving means is rotated in a circular manner, and the pusher 17 attached to the chain I6 abuts and locks the rear end of the movable frame of the conveyance unit to suppress the movement. During this movement, the V-shaped tip of the stopper 18 located at each processing process location
4, the movable frame l of the transport unit can be moved at predetermined pitches. In this embodiment, since the guide rollers 14 are provided at the same pitch as the arrangement pitch of the electronic component bodies 13, the conveying unit can be made to move t at the same pitch as the arrangement pitch of the electronic component bodies 13.

<Effects of the Invention> As described above, according to the present invention, the frame-equipped electronic component is held and transported by the transport unit, thereby eliminating any transport troubles and troubles caused by changing the frame. In addition, the frame of the electronic component is held in the straight grooves of both clamping members over its entire length, so it is always maintained in a constant posture without being affected by warping or deformation of the frame, so it can be easily maintained in each process. Processing becomes easier.
