Abstract

PURPOSE:To facilitate handling simplifying a structure by providing a vertically movable chute by driving a cam and a horizontally reciprocatable transfer feeder, having two or more workpiece holding parts, and combining chute vertical movement with transfer feeder movement, in the case of a transfer feed mechanism for a semiconductor element or the like. CONSTITUTION:An electronic part 10 is straightened by a magazine 9, fed to a retaining stopper 14 and stopped. Next moving a chute part 5 to the upper by a cam 6, the part 10, falling off from the stopper 14, is accepted into the chute part 5 as shown by (a) in the drawing. Next lowering the chute part 5, the part is positioned and held in a workpiece holding part 1. Subsequently, a transfer feeder 3 is moved to the right by a driving gear 4, feeding the part transferring to a position (b) of the chute part 5. Next lifting the chute part 5, the part 10 is removed from the workpiece holding part and held to the position (b) in the chute part 5. By this constitution, handling is facilitated for a mechanism simplified in its constitution.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for transporting electronic components such as semiconductor devices.

In the manufacturing and inspection processes of electronic components such as semiconductor elements, resistors, and capacitors, electronic components that are lined up without any gaps are separated at predetermined intervals, and at the separated positions, they are processed and processed as necessary.
In response to the demand for a transfer mechanism to perform processes such as testing, conventionally there was a transfer mechanism for electronic components that held the electronic components with a vacuum chuck, etc., and then moved and placed them at a predetermined position on the chiffle. . However, conventional mechanisms require complicated structures to automatically perform accurate positioning.
As a commercial machine, there were economic difficulties as well.

Furthermore, when transferring many types of electronic components with different external dimensions, the conventional mechanism requires changes to holding parts, positioning parts, etc., and has the drawbacks of being structurally complex, difficult to use, and expensive.

The present invention solves the above-mentioned drawbacks of the conventional mechanism, divides a plurality of electronic components into parts at predetermined intervals accurately, and, at predetermined positions,
Processes such as processing and inspection can be carried out with high precision, and the structure,
To provide an electronic component transfer mechanism that is easy to handle. Furthermore, it is possible to transfer a wide variety of electronic components with different shapes without having to change each part P4. Serve the side.

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a structural diagram showing an embodiment of the present invention, where 1 is a work holding part, 2 is a
3 is a transfer body, 4 is a drive source for horizontal reciprocating movement, 5 is a single movable chute, 6 is a drive cam, 7 is a spring that is a downward pressure means, 8 is a spring that is a two-way pressure means; Pressure means for feeding; 9 is a magazine; 10 is an electronic component; ]] is a position stopper; 12 is a screw for adjusting the position spacing 1; 13 is a processing or inspection device; 14 is a presser foot 1 to a collar.

In FIG. 1, electronic components 10 that are continuously arranged in a magazine 9 are pushed with constant weak pressure by a feeding pressure means 8 consisting of a constant torque motor and a plate spring.
Feed it into the presser foot stopper 14 part. Next, by raising the vertically movable chute section 5 by the drive cam 6, the part 10 that has come off the presser foot 1 header 14 enters the shoe 1 section 5 and is fed to the position T. (
It will be in position b). Therefore, when the drive cam 6 is rotated and the part 5 is lowered to the shoe 1 by the downward means in the direction of the downward arrow, it simultaneously enters the vortex of the workpiece holding part 1 or the shoes 1 to 1 and holds the electronic component 0. do. At this time, the electronic component is held in the recess 1 under pressure by the springs of the upward pressing means. Further, by the transport body 3 provided with 1 or the drive source 4 for horizontal reciprocating movement, it is horizontally moved in the direction of the arrow pointing to the right in the figure,
The electronic component 10 is transferred to the position (B) within the shoes 1 to 5. When the workpiece is transferred to the position (B), the drive cam 6 rotates again, the chute part 5 rises against the downward pressure means, the electronic component 10 is removed from the recess of the workpiece holding part, and the chute part 5 is moved up. It is held at position (b) in section 5. Processing at position (0) or by inspection device 13,
Processing or inspection is performed. Next, a new electronic component] 0 is fed from the stopper] 1 side into shoes 1 to 5 (a), and the recess of the workpiece holding part is returned to the original position corresponding to (a) by the drive source 4. As the shoe part 5 descends, it is held under pressure.

By repeating such operations, the electronic component 0 is transferred to each position (a), (b), (c), and (d). 13 in each position
A processing or inspection device is provided as necessary to perform cutting, forming, characteristic inspection, etc. of lead frames such as semiconductor devices.

The drive cam of the shoe 1 part 5 uses an elliptical or eccentric cam, and can be easily moved downward. When applying the present invention to electronic components of many different shapes, the first
By making the shape of the concave part of the work holding part 1 shown in the figure step-like, electronic components can be held at the position of the planned width of the concave part.
Since accurate positioning is possible, there is no need to change the workpiece holding section, and excellent effects can be achieved in terms of both handling and economy.

FIG. 2 is a cross-sectional structural view showing a state in which the shoes 1 to 5 have been lowered and the electronic component 0 is held in the workpiece holder 1.

The same parts as in FIG. 1 are designated by the same reference numerals. Figures 2<a), N)) and (C) respectively show the state in which electronic components 10 of three different shapes are held. FIG. 3 is a side structural view of FIG. 2.

As mentioned above, the present invention uses a horizontally reciprocating transport body provided with a chute part that moves up and down by a combination of a drive cam and a downward pressure means, and a workpiece holding part with an upward pressure means, to achieve accurate movement. Transfer electronic components at intervals and process them at predetermined locations.
The transfer mechanism is capable of carrying out processes such as inspection, and by making the concave shape of the work holding part step-like, it is possible to transfer electronic components of different shapes without changing the work holding part.
