Description

[Detailed explanation of the invention] Industrial application field This invention is applicable to chip parts such as capacitors and resistors,
In particular, the present invention relates to a component positioning device that is suitably used when setting rectangular components or the like in a predetermined position.

Conventional technology For example, when attaching lead wires to both sides of a square pellet that is a semi-finished product, the lead wires are conveyed by a chain lead or the like, so the pellets are placed in a predetermined place in order to securely connect the two. It was necessary to position accurately.

As shown in FIG. 3, such a conventional positioning device 21 includes a block-shaped base 22 with a flat upper surface on which the pellet A is placed, and a large number of block-shaped bases 22 are connected. It is integrally formed.

Problems to be Solved by the Invention However, in such a positioning device 21, when the pellet A is placed on the block-shaped base 22, the pellet A is normally transported by the conveying jig 26 equipped with the suction port 25. Since the pellets A rotate and tilt when the conveyance jig 26 is withdrawn, the position and direction of the pellets A change, and the lead wire 23 is conveyed sequentially by a chain lead (not shown).
There was a problem in that the connection between the two parts could not be established reliably, resulting in a high number of defective products and a lower yield rate.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a positioning device that can ensure the positioning of parts.

Means for Solving the Problems In order to achieve the above object, the present invention forms a tapered guide groove that is open on at least one side and whose side wall is narrow in the depth direction. The bottom surface is formed to be almost the same as the dimension width of the part, and a pair of ridge lines that form the boundary between the top surface and the guide groove are
a device body formed gradually narrower from the opening side;
It is characterized by comprising a push plate that slides freely forward and backward along the length direction within the guide groove.

Effects According to the above structure, when the transport jig is released from adsorption to the guide groove formed in the apparatus main body and is pushed into the inner part of the guide groove with the push plate from one side of the opening side, the Since the component slides down to the bottom surface of the groove while being guided by the tapered side wall of the guide groove and the push plate, the front, rear, left, and right directions are regulated and the component is reliably placed in a predetermined direction and position.

Examples Examples of the present invention will be described below. FIG. 1 is a perspective view of a component positioning device according to the present invention.
In the figure, reference numeral 1 denotes a device main body having a guide groove 2 formed on its upper surface with a depth approximately half of the height of a rectangular pellet A before a lead wire is attached as a semi-finished product. Note that although the drawings show one device body 1, a plurality of devices are generally used in a connected manner. The guide groove 2 is formed with both side surfaces open, and the width of the bottom surface 2a is equal to the width of the pellet A.
The both side walls 2b are formed in a tapered shape that gradually narrows from the top surface 2T side to the bottom surface 2a side, and at the same time, the boundary between the top surface 2T and the side wall 2b of the guide groove 2. The ridgeline 2l is
It is gradually narrower from the front side to the back side in the drawing. Reference numeral 3 denotes a push plate configured to move forward and backward in the longitudinal direction of the guide groove 2, and can push the pellet A placed on the front side of the guide groove 2 to the rear.

Use of this device is as follows. A conveying jig 12 having a suction port 11 sucks the pellet A and places it near the front of the guide groove 2 of the apparatus main body 1. Next, the press plate 3 is brought into contact with the pellet A and pushed into a predetermined position at the back. Then, the pellet A is regulated in its left and right positions by the tapered side walls 2b of the guide groove 2, and at the same time is fed to a predetermined position in the front and rear directions by the push plate 3. That is, from the time when the transport jig 12 is released from suction, the pellet A slides down to the bottom surface 2a while being guided by the side wall 2b and the push plate 3. In this example, since the width of the pellet A and the width of the guide groove 2 are made the same, accurate positioning is possible. Therefore, the chain lead (not shown)
Since the pellets A are placed at predetermined positions, the pellets A and the lead wires 13 are always connected reliably.

In the above embodiment, both sides of the guide groove 2 are shown open so that pellets A of different lengths can be placed in a predetermined position by changing the pushing amount of the push plate 3. However, the same effect can be obtained even if the guide groove is formed with a closed inner side.

The parts to be positioned by this device are optimally the aforementioned semi-finished pellets A and the finished square chip parts, but are not limited to square parts and can be positioned by the guide groove 2. If it is possible to position the parts in the front, back, left and right directions, it is also possible to position parts with arbitrary shapes such as polygons.

Effects of the Invention As described above, in the component positioning device of the present invention, the side wall of the guide groove formed in the main body of the device on which the component is placed is formed into a tapered shape, and the side wall is gradually narrowed in the length direction. , a push plate that can move forward and backward in the length direction of the guide groove is provided, and the parts are placed on the guide groove and pushed by the push plate, so that the parts are regulated in any of the front, rear, left, and right directions; set in place. Therefore, when connecting a lead wire or the like to the component, the component and the lead wire are securely fixed, reducing the occurrence of defective products and improving the yield rate, which in turn reduces product costs. Contributes to the reduction of
