Abstract

PURPOSE:To simplify operations for setting and removing a chip component and to enable application of a device to chip components having different dimensions and shapes by a construction wherein a fixed holding piece is fixed on the upper surface of a base block in each accommodation space. CONSTITUTION:A movable holding piece 23 faces a fixed holding piece 22 with a chip component 1 held between in each accommodation space, and it is joined to a longitudinal beam member through the intermediary of a coil spring 25. The holding piece 23 is moved in the direction of separation from the holding piece 22 by the spring 25 acting as a tension coil spring. Therefore a large space can be formed between the holding pieces 22 and 23 and the component 1 can be put on a base block so that a base having an electrode 2 formed is brought into contact with the upper surfaces of a fixed-side electrode plate 32 and a movable-side electrode plate 33 corresponding thereto. When an opening-closing cover 30 is closed, a leaf spring 31 fitted oppositely to each accommodation space presses the component 1 onto the upper surface 11A side of the base block. Accordingly, the electrode 2 of the component 1 comes into close contact with the electrode plate 32 or 33 corresponding thereto and the electrode 2 is connected to the main body of a tester through a connection wire 8.

[Industrial application field]

TECHNICAL FIELD The present invention relates to a component setting device for a testing machine used when testing characteristics of two-electrode chip components such as capacitors and resistors.

Chip components such as capacitors, resistors, or semiconductor components are generally mounted on circuit boards after conducting characteristic tests in advance.

It is desirable that such characteristic tests can be carried out efficiently.

[Conventional technology]

FIG. 3 shows a conventional method of setting chip components when performing a characteristic test.

In FIG. 3, reference numeral 1 indicates a two-electrode chip component such as a capacitor or a resistor. Electrodes 2 are provided on a pair of opposing side surfaces of the low rectangular parallelepiped main body of the chip component 1 and a portion of the bottom surface connected to the side surfaces.

Conventionally, when performing a characteristic test of the deep part 1, the chip part 1 is temporarily mounted by soldering onto a printed board 3 configured to be plugged into a testing machine main body (not shown).

To be more specific, a plurality of pairs of patterns 4 are provided in parallel on the card edge type plug portion 5 of the printed board 3, and pads 4A are formed at the terminals of each pair of patterns 4 to face each other.

The electrodes 2 are aligned on these pads 4A, the chip components 1 are soldered, and the plurality of chip components 1 are mounted in parallel on the printed board 3.

The characteristic test of the chip component 1 is carried out by connecting the electrode 2 to the electric circuit of the corresponding test machine main body.

[Problem to be solved by the invention]

As mentioned above, the conventional method is to solder a chip component to a printed board each time, conduct a characteristic test, and after the test is completed, heat and melt the solder and remove the chip component 1 from the printed board 3. There was a problem in that it took a lot of time to set up the chip parts.

On the other hand, during soldering, repeating the process of sticking and remelting the solder several times causes the pad portion of the printed board to peel off and become damaged.

Furthermore, there are several types of chip components to be tested that have approximately the same height and different rectangular dimensions in plan view.

Therefore, pads matching the shape of each electrode are required, which poses a setup problem in that a large number of printed boards must be prepared.

The present invention was created in view of these points, and an object of the present invention is to provide a component setting device that allows easy attachment and detachment of chip components and can be applied to chip components of different sizes and shapes.

When sliding in the opposite direction, that is, in the direction of arrow A, the fixed clamping piece 22 is fixed to the top surface 118 of the base and does not move, but the movable clamping piece 23 is moved by the coil spring 25 acting as a tension coil spring. It moves in a direction away from the fixed clamping piece 22.

Therefore, between each pair of fixed clamping pieces 22 and movable clamping pieces 23, there is a space that is sufficiently larger than the plan view shape of the chip component 1 of the maximum size, and the chip component 1 can be fixedly clamped in each square 21. It is inserted between the piece 22 and the movable clamping piece 23, and the bottom surface on which the electrode 2 is formed is attached to the corresponding fixed side electrode plate 32. The chip component 1 can be placed on the base 11 so as to be in contact with the upper surface of the movable electrode plate 33.

Next, as shown in FIG. 2 fb), move the slider 20 toward the fixed clamping piece 22 using the front and rear edges of the square window 13 as guides.

That is, when sliding in the direction of arrow B, the coil spring 25 acts as a compression coil spring or tension coil spring, and the movable clamping piece 2

〔Example〕

The present invention will be specifically described below with reference to the drawings. Note that the same reference numerals refer to the same objects throughout the plan.

FIG. 1 is a configuration diagram of an embodiment of the present invention, in which (a) is a perspective view and (bl is a sectional view).

In FIG. 1, reference numeral 10 indicates that the chip component 1 is set in parallel on the base 11, and the electrode 2 of the chip component 1 and the testing machine main body (
(not shown) via a connection vA8, which includes a base 11, an outer frame plate 12, a slider 20 slidably mounted inside the outer frame plate 12, and a It consists of an opening/closing cover 30 that covers the square window 13 and the like.

The outer frame board 12 is almost in the shape of a picture frame, and a horizontally long rectangular window 1 which is smaller than the base 11 and which is desirably smaller than the base 11 is provided.
3, and is fixed to the base 11 by screwing or the like with its lower surface in close contact with the upper surface of the base 11.

The lattice-shaped slider 20 is inserted into the rectangular window 13 of the outer frame board 12, and the lower surface slides on the base top surface 11A using the front and rear side edges of the rectangular window 13 as guides, so that the slider 20 slides inside the outer frame board 12. It is attached so that it can be slid in the left and right direction.

This slider 20 includes a plurality of (four in the figure) horizontal beam members 2.
Rectangular squares 21 that are long in the left-right direction are arranged in a matrix (nine squares in the figure) using 08 and a plurality (four in the figure) of vertical beam members 20B.

A notch is formed in the center of one vertical frame member of the outer frame plate 12, and an eccentric cam 36 for moving the slider 20 is mounted in this notch.

To be more specific, the eccentric cam 36 passes through the vertical frame member horizontally in the front-rear direction and is fixed to the drive shaft 35 which is supported.

Therefore, when the lever provided at one end of the drive shaft 35 is tilted, the eccentric cam 36 rotates and its eccentric protruding surface comes into contact with the outer surface of the longitudinal beam member 20B of the slider 20, so that the slider 20 It slides within the rectangular window 13 in the opposite direction to the eccentric cam 36 (to the left in the figure).

On the other hand, a compression coil spring 37 is installed between the vertical beam member 20B of the slider 20 and the vertical frame member of the outer frame plate 12 on the opposite side of the eccentric cam 36.

Therefore, when the eccentric cam 36 is not driven, the slider 20 is moved around the rectangular window 13 by the elasticity of the compression coil spring 37.
It is located on the eccentric cam 36 side (toward the right in the figure).

Reference numeral 22 denotes a rectangular parallelepiped-shaped fixed clamping piece that is long in the front-rear direction, and a wedge-shaped notch 228 is provided in the center of the vertical plane facing the movable clamping piece 23, and both vertical surfaces of the wedge-shaped notch 22A are used to hold the chip. It is designed so as to come into contact with two surfaces sandwiching the corner of the component 1.

Such fixed clamping pieces 22 are placed in each square 21,
One of the vertical beam members 20B (in the figure, the vertical beam member 20B on the side of the compression coil spring 37) is fixed with its bottom surface in close contact with the base upper surface 11A.

Reference numeral 23 denotes a movable clamping piece having almost the same shape as the fixed clamping piece 22, and a wedge-shaped notch 23A is provided in the center of the vertical plane facing the fixed clamping piece 22, so that both vertical surfaces of the wedge-shaped notch 23^ , so as to come into contact with two surfaces sandwiching the corner of the chip component 1.

Such a movable clamping piece 23 is fixed to the fixed clamping piece 2 in the square 21.
2 and connected to the other vertical beam member 20B via a coil spring 25.

Therefore, the movable clamping piece 23 moves following the slider 20, and also slides in the horizontal direction within the square 21 to move closer to or away from the fixed clamping piece 22 by driving the slider 20.

On the other hand, each fixed clamping piece 22. A fixed electrode plate 32 and a movable electrode plate 33 are provided on the upper surface 118 of the base in correspondence with the movable clamping piece 23.

Each fixed side electrode plate 32. The movable electrode plate 33 has a thin rectangular shape, and has terminals 32A and 33^ on the back surface that penetrate through the bottom surface of the base 11, respectively.
33A is a terminal connected to the connection 18 which is connected to the main body of the test machine (not shown).

Fixed side electrode plate 32. Both surfaces of the movable electrode plates 33 correspond to the base upper surface 11A, and are arranged in parallel at positions corresponding to the respective cells 21.

30 is an opening/closing cover that covers the rectangular window 13 and is hinged to the side edge of the outer frame board 12. A tongue-shaped plate spring is provided on the side edge of the opening/closing side of the opening/closing cover 30 to be pushed into and engaged with an engagement recess provided on the side surface of the outer frame plate 12, so that the opening/closing cover 30 can be held in a closed state. It is composed of:

Now, leaf springs 31 are attached to the inner surface of the opening/closing cover 30 at locations facing each of the cells 21.

This leaf spring 31 presses the chip component 1 inserted into each cell 21 against the top surface 11A of the W stand with the open/close cover 30 closed.

Since the component setting device 10 of the present invention is configured as described above, the slider 20 is normally guided by the front and rear edges of the rectangular window 13 by the elasticity of the compression coil spring 37, and is opposed to the fixed clamping piece 22. It stops at a position moved in the direction, that is, in the direction of the eccentric cam 36.

Therefore, as shown in FIGS. 1 and 2, the coil spring 25 acts as a tension coil spring, and the movable clamping piece 23 moves in a direction away from the fixed clamping piece 22. Between the clamping piece 22 and the movable clamping piece 23,
A space that is sufficiently larger than the plan view shape of the chip component 1 of the maximum size is created.

In such a space formed in each square 21, one corner of the chip component 1 is formed into a tree-shaped notch 22 of the fixed clamping piece 22.
The chip component 1 is inserted into A so that the other diagonal corner faces the tree-shaped notch 23^ of the movable clamping piece 23 and the bottom surface rests on the top surface 11A of the base.

Next, when the drive shaft 35 is rotated by hand to rotate the eccentric cam 36, the slider 20 is fixed using the front and rear edges of the rectangular window 13 as guides against the elasticity of the compression coil spring 37. The clamping piece 22 slides in the direction.

Therefore, the coil spring 25 acts as a compression coil spring and a tension coil spring to fix the movable clamping piece 23 to the clamping piece 2.
Pushing in two directions, the movable clamping piece 23 pushes the chip component 1, the bottom surface of the chip component 1 slides on the base top surface 11A and moves toward the fixed clamping piece 22, and the chip component 1 moves between the fixed clamping piece 22 and the movable clamping piece. 23.

This sandwiched position is like, ! Each electrode 2 of the knob component 1 is attached to a corresponding fixed side electrode plate 32 . Movable side electrode plate 33
It is a predetermined position that is in contact with the .

Then, when the opening/closing cover 30 is closed, each cell 21
A leaf spring 31 mounted facing the presses the chip component 1 toward the top surface 11A of the base. Therefore, the electrodes 2 of the chip component 1 are connected to the corresponding fixed side electrode plate 32. Alternatively, it is brought into close contact with the movable electrode plate 33, and the electrode 2 is connected to the testing machine main body via the connecting wire 8.

When the characteristic test is completed and the drive shaft 35 is rotated to its original state,
Due to the elasticity of the compression coil spring 37, the slider 20 moves and returns to its original state.

Therefore, the 71 parts can be easily taken out from inside each cell 2I.

The component setting device 10 of the present invention is not only versatile because it can simultaneously set chip components having different shapes and dimensions as described above, but also extremely easy to attach and detach chip components.

Note that the fixed clamping piece 22. The movable clamping piece 23 may have a simple rectangular parallelepiped shape, but if it is provided with a tree-shaped cut, the position at which the chip component is clamped can be set to a predetermined value, and the reliability of the connection between the fixed side electrode plate and the movable side electrode plate can be improved. It has the advantage of being high.

Furthermore, the means for moving the slider 20 is not limited to the combination of the eccentric cam 36 and the compression coil spring 37, and the slider 20 may be moved directly by hand, for example.

〔Effect of the invention〕

As explained above, in the present invention, a fixed clamping piece and a movable clamping piece are installed in each of the sliders to hold the chip component in a predetermined position and press the electrode against the opposing electrode plate. This component setting device has excellent practical effects such as easy attachment and detachment of chip components, and is applicable to chip components of different sizes and shapes, and is versatile.
