Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention transports electronic components with frames, in which electronic component bodies such as ICs are arranged and connected at a constant pitch between a pair of frames via lead terminals. Regarding the method.

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

<Problems 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 other external forces, leading to transport problems. It was the reason for the invitation.
Furthermore, if transportation troubles occur and the frame is significantly deformed, it becomes unusable for further processing, and many electronic components must be disposed of. Further, similar problems occur with the method of locking the electronic component body, and there are also problems such as difficulty in achieving pitch feed accuracy due to molding errors and molding burrs in the mold portion.

In addition, in these conventional methods, since electronic components with frames are loaded into the same transport device for each processing step, the frames must be re-griped many times, increasing the chances of problems with re-gripping. It was hot.

The present invention aims to provide a method for safely and reliably transporting electronic components with a frame, and for feeding the electronic components at fixed pitches.

<Means for Solving the Problems> In the present invention, a pair of clamping members having linear grooves along the moving direction of the underframe are provided on a movable underframe that can be moved in one direction by a grounding wheel. In addition, a transport unit is prepared in advance in which a group of guide rollers are provided on both the left and right sides of the movable frame at the same pitch as the arrangement pitch of the main body of the electronic component with the frame, and the electronic component with the frame is placed in the linear groove of the transport unit. The outer edge of the frame is engaged and held over the entire length to enable the electronic components to be moved together with the transport unit, and the transport unit is arranged between guide rails that can roll into guide rollers on both the left and right sides of the transport unit, and the The transport unit is positioned at the arrangement pitch of the electronic component bodies by engagement between the stopper that moves in and out of the electronic component body and the guide roller.

<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, there is less need to change the frame of the electronic component.

Since the transport unit is movable using ground wheels, electronic components can be removed from the production line and set on the transport unit as a whole.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of a conveyance unit used to carry 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 platform frame 1, allowing the device to move on the device base 4 as shown in FIG.

The clamping members 2, 2 are formed into long flat plates in the front and back, and are disposed facing each other on the left and right sides in an upright position, and each of the supporting shafts 6, 6, which are inserted into and fixed to gear members 5, 5 that engage with each other, are movable on the opposing inner surfaces. It is supported by brackets 7, 7 erected at the front and rear of the underframe 1, and is interlocked so that the upper parts of both clamping members 2, 2 move toward and away from each other. Further, tension springs 8, 8 are tensioned between both the clamping members 2, 2, so that both the members 2,
2 are urged to rotate in a direction toward each other, and the limits of rotation are restricted by contact with the left and right shoulders of the brackets 7, 7. Also, one end of the support shaft 6 protrudes from the bracket 7, and a lever 9 is attached thereto.
is attached so that both clamping members 2, 2 can be swung open against springs 8, 8 by operating a lever from the outside.

V-shaped straight grooves 10, 10 are respectively formed on the inner surfaces of the upper ends of both the holding members 2, 2 over the entire front and rear lengths, and the outer edges of the left and right frames 12, 12 of the electronic component 11 with a frame are formed over the entire length. It is configured so that it can be inserted and held across the body.

Further, on both the left and right sides of the movable frame 1, guide rollers 14 groups made of bearings are provided at the same pitch as the arrangement pitch of the electronic component main body 13. As shown in FIG. 2, this guide roller 14 acts on a guide rail 15 provided on the device base 4, and moves the movable frame 1 to the guide rail 15.
We will guide you through step 5.

Further, between the guide rails 15, 15, a conveyance chain 16 serving as a driving means for moving the movable underframe 1 is arranged so as to rotate in circulation, and a pusher 17 attached to this chain 16 moves the rear end of the underframe. It is configured to abut and lock and press and move.

As shown in FIG. 4, a stopper 18 is provided at the end of the conveyance path or at various processing 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 intervals.

In the present invention, a conveyance unit having the above configuration is prepared in advance, and the lever 9 of this conveyance unit is operated to open both the clamping members 2, 2 against the springs 8, 8. The outer edges of both frames 12, 12 of the electronic component 11 are engaged and held in the straight grooves 10, 10 over their entire lengths.

Next, a conveying chain 16 as a driving means is rotated in a circular manner, and a pusher 17 attached to the chain 16 abuts and locks the rear end of the movable frame of the conveying unit and presses it. During this movement, the V-shaped tip of the stopper 18 located at each processing step engages with the guide roller 14, so that the movable frame 1 of the transport unit can be moved at every predetermined pitch. can. In addition, in this embodiment, the guide rollers 14 are provided at the same pitch as the arrangement pitch of the electronic component main body 13.
The transport unit can be moved 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, since the electronic component with frame is held and transported by the transport unit,
There is no need to worry about transportation troubles or 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 warpage or deformation of the frame, so each process processing becomes easier.

Furthermore, since the transport unit that holds the electronic components with the frame can be moved independently using ground wheels, the electronic components can be removed from the production line and set on the transport unit as a whole.
Even if the production line is not continuous, movement between processes can be performed without any problems. Further, by holding the frame-equipped electronic component in advance in a transport unit removed from the production line, the electronic component can be quickly delivered to the production line.

Furthermore, since the transport unit can be moved while being positioned at the same pitch as the arrangement pitch of the electronic component bodies, the electronic component bodies can be directly subjected to the required processing steps via this transport unit. Moreover, in this case, the frame-equipped electronic component is held in the linear groove of the conveyance unit, and its position can be adjusted steplessly and minutely in the direction of movement of the conveyance unit. By adjusting the position of the parts, the main body of the electronic parts can be accurately set at the processing position for each process.

In addition, since a group of guide rollers is provided on both sides of the movable frame of the conveying unit, the conveying unit can be moved in a stable posture with little resistance by rolling contact between the group of guide rollers and the guide rail.
