Abstract

PURPOSE:To set the movement distance of a wire tip freely in a final stage and thereby make possible the fine-adjustment of the wire to make the quality of an inker uniform by fitting fine tube at the tip to the external side of wire in a condition that the body of a bottle and the fine tube at the tip are separated or engaged together in a freely slidable manner, and fixing the fine tube to a bottle connected on section through the adjustment of the former's position in a final stage. CONSTITUTION:Wire 5 is connected to the tip of a rod 1b on a plunger 1 using an adhesive or any other means. Next, fine tube 7 which is engaged in a freely slidable manner with the body 6 of an ink bottle and the connection section 6' of the body of the bottle is fitted externally from the tip side of the wire. Then the rear end of the body 6 is pressed into the installation section 3' of a block 3 and is fixed. In this case, the fine tube 7 is put on the wire 5 in a condition that it is not fixed to the connection section 6' of the body 6. After this, the fine tube 7 is moved forward or backward while it slides through the connection 6, of the bottle, and is adjusted to a desired position. Finally the engaged parts of the connection section 6' of the bottle and the fine tube 7 are fixed with an adhesive. Consequently, it is possible to make the movement distance of the wire 5 coming out of and retracting into the fine tube 7 free and constant, if there is an error in the size of a member, and obtain the product of uniform quality efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] This invention relates to a method of manufacturing a marking inker for making dot marks on electrical components such as ICs and recording sheets of recorders and the like.

[Background technology of the invention]

A marking inker is known in which an ink extrusion wire is connected to a plunger operated by an electromagnetic solenoid, and this wire is passed through an ink bottle having a thin tube at its tip so that the tip of the wire emerges and retracts from the tip of the thin tube. In addition, in this type of marking inker, a bulge is formed at the tip of the wire, and a locking portion is provided on the thin tube to engage the wire bulge, so that the wire bulge and the capillary locking portion are engaged. There is a stopper type marking inker that prevents ink from dripping.

[Problem that the invention seeks to solve]

Conventionally, when assembling these marking inkers, the wire was passed through the &tor and the thin tube at its tip, which were made inseparable, which caused the following problems.

First, since the length of the entire ink fountain including the capillary is fixed, if the length of the wire from the plunger light leakage is different, there will be an error in the length of the wire that emerges and retracts from the tip of the capillary, resulting in uneven quality. Become. In this case, the wire tip is cut to a uniform length, but the wire tip requires special processing such as polishing, so if it is cut off, it must be reprocessed, especially for ink bottles. Processing after assembly is difficult and inefficient.

In addition, in the stopper-type marking inker, a synthetic resin wire is adhesively fixed to the tip of a pusher supported on the bottle lid, and a thin tube is integrally fixed to the tip of the ink bottle, so that the wire protrudes from the tip of the thin tube. The upper end of the bottle is fixed to the lid through the wire, and the tip of the wire is then heated to form the bulge.However, this assembly method uses a constant wire size, but it is difficult to form the bulge. In this case, the length of the wire becomes uneven due to heat shrinkage, making it difficult to obtain a homogeneous product.

An object of the present invention is to provide a method for assembling a marking inker, which allows the movement stroke of the tip of the wire that emerges and retracts from the thin tube to be arbitrary and constant even if there is an error in the dimensions of the members. Another object of the present invention is to provide a method for assembling a marking inker in which the above assembly can be performed after a bulge is formed at the tip of the wire in advance.

[Means to solve the problem]

The above-mentioned main object of the present invention is to connect an ink extrusion wire to the tip of a granger which is elastically supported by a support block of a marking ink crab so that it can move back and forth, and connect the gettle to a thin tube to be attached to a connecting portion at the tip of an ink bottle. Separate again. is slidably fitted over the wire to fix the rear end of the bottle to the support block, and then, after moving and adjusting the thin tube to a desired position along the bottle connection part, the thin tube is attached to the bottle. This can be achieved by fixing it to the connecting part. In this case, a diameter-reducing locking portion is provided in the hollow interior of the thin tube, and after passing the wire through the thin tube, a bulge portion that engages with the thin tube locking portion is formed at the protruding end of the wire. Thereafter, the position of the thin tube may be adjusted in accordance with the desired forward/backward stroke of the bulging portion at the tip of the wire, and fixed in the &l-ru.

Another object of the present invention is to loosely fit a hollow tube formed with a locking part of the wire bulge into a wire having a bulge at its tip, so that the wire can be elastically moved forward and backward into a support block of a marking inker. The rear end of the wire is connected and fixed to the tip of the supported plunger, and then the wire and the thin tube are inserted into the ink bottle and protruded toward the tip side, and the thin tube is slid onto the connecting member at the tip of the ink bottle. Fixing the rear end of the ink &) to the support block in a freely fitted state,
This can be achieved by subsequently moving and adjusting the capillary tube to a desired position along the &tor coupling portion, and then fixing the capillary tube to the yt'')ru coupling member.

[Action of the invention]

In the present invention, the wire is passed through the bottle body and the thin tube attached to the tip of the bottle body, which are separated or slidably fitted together. ) After fixing the tube to the plunger support, only the capillary tube can be independently positioned and fixed to the bottle. Therefore, the length of the wire that protrudes and retracts from the tip of the thin tube can be arbitrarily selected and made uniform regardless of the dimensional error of the wire. This effect is the same when forming a bulge at the tip of the wire after attaching the dettle.

Further, since the thin tube is separated from the bottle body, only the thin tube can be fitted in advance to a wire having a bulge formed at the tip thereof, and the yl=') can be placed at a predetermined position later. In either case, the final step is to position the thin tube and fix it to the bottle body.
