Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a two-terminal element holding device, and more specifically, to an element such as a diode having lead wire terminals at both ends, when the surface is inspected. The present invention relates to a two-terminal element holding device suitable for holding.

[Prior Art] Many of the elements of this type used in electronic devices have an extremely fine shape with a total length of about 10 mm, and a microscope has been used to visually inspect the entire circumference of the surface of such an element.
Therefore, a rotating jig for holding the element is required.

FIG. 2 shows an example of such a conventional rotary clamp jig. Here, reference numeral 1 is a rotary clamp jig, and a lead wire gripping groove 2 is formed at a tip end portion thereof so as to be aligned with the rotation axis center 1A, and in this gripping groove 2, one lead wire 4 of the two-terminal element 3 is formed. Are fitted together. Reference numeral 5 denotes a clamp member capable of gripping the lead wire 4 fitted in the grip groove 2 from above with the spring force of the spring 6.

Therefore, when the two-terminal element 3 is to be held by the rotary clamp jig 1, one lead wire 4 of the two-terminal element 3 is pinched by, for example, tweezers 7 as shown in the figure, and the clamp member 5 is pressed against the spring 6. And the clamp member 5 is returned so that the other lead wire 4 is aligned with the grip groove 2 and thus the element 3 main body and one lead wire 4 are held by the rotary clamp jig 1 in a protruding state. .

[Problems to be Solved by the Invention] However, in the conventional two-terminal element holding device as described above, since the element 3 is too small, the workability is very poor, and it is difficult to grasp accurately. And lead wire 4
It is not easy to insert it in the grip groove 2 so as not to force it.

Further, since one of the lead wires is gripped by the jig 1, this portion cannot be inspected unless it is gripped again.

The object of the present invention is to focus on the above-mentioned conventional problems, and in order to solve the problems, it is possible to safely hold the two-terminal element and to easily perform visual inspection of the entire two-terminal element. An object is to provide an element holding device.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a non-magnetic rotating member that is rotatable around an axis and a rotating member that is provided at an opposing position with a predetermined distance from the rotating member. The fixed member and the rotating member each have a magnet whose magnetic poles are aligned with the axial center, and the magnetic force generated between both magnets attracts the lead wire of the two-terminal element. The two-terminal element is rotatably held via a rotating member.

[Operation] According to the present invention, the lead wires of the element are attracted in opposite directions by the magnetic force between the magnets provided on the two-terminal element only by guiding it to the space between the rotating member and the fixed member. Since it is held by, the device can be inspected easily without applying unreasonable force to the device.

[Embodiment] An embodiment of the present invention will be described in detail and specifically below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. Where 11 is the axis of rotation
A rotary member attached to the tip of 12 and rotatable with the rotary shaft 12, 13 is a fixed member provided at a position facing the rotary member 11, and the fixed member 13 is, if necessary, along the rotary shaft center 11A. It is made movable so that the relative distance to the rotating member 11 can be adjusted appropriately. The rotating member 11 and the fixed member 13 are both made of a non-magnetic material. Reference numerals 14 and 15 are magnets, and these magnets 14 and 15 are embedded in the rotating member 11 and the fixed member 13 so that their magnetic poles coincide with the rotation axis center 11A. Further, 16 is from the magnet 14 to the shaft center 11
A and a magnetic core member embedded in the rotating member 11 in accordance with the magnetic poles, and 17 in the same manner from the magnet 15 of the fixed member 13 to the shaft core.
It is a magnetic core member embedded along 11A. In this example, the tip of the core member 17 is somewhat embedded in the fixing member 13, and the two-terminal element 3 rotates. It is designed to be easily held on the side of the member 11.

Therefore, in the two-terminal element holding device thus configured, the magnetic flux density between the core members 16 and 17 is kept high by the magnetic field formed between the opposite poles of the magnets 14 and 15 which face each other. Therefore, by simply bringing the two-terminal element 3 between them and leaving it alone, as shown in the figure, one lead wire 4 of the element 3 is entirely held in the space in the form of being attracted to the core member 16 by the magnetic force. Moreover, since this state does not change even when the rotating member 11 is rotated, the appearance of the two-terminal element 3 can be visually inspected from any direction while rotating the rotating member 11 by the rotating shaft 12.

In the embodiment described above, the magnetic core members are provided in the directions facing each other from the respective magnets of the rotary member and the fixed member, but the core members themselves may be replaced as magnets. Of course.

[Advantages of the Invention] As described above, according to the present invention, magnets are provided such that the magnetic poles of the rotating member and the fixed member made of a non-magnetic material are aligned with the rotation axis, and the magnetic force obtained between them is obtained. Since the two-terminal element is held by the lead wire by means of the above, the lead wire of the element can be held in one side only by guiding the two-terminal element to the space between the rotating member and the fixed member. By rotating the rotating member around the axis of rotation, the element can also be rotated and the surrounding area can be visually inspected freely, which saves time and effort and does not force each part of the element. It became possible to hold it in the state.
