Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrostatic recording head manufacturing apparatus E1m for an electrostatic recording device.
It is something to do. Electrostatic Recording - The method generally has two basic R#s. The first step is to electrically charge selected portions of the recording medium by an electrostatic recording head connected to a charging circuit, The step o*2 of forming an electrostatic latent image is that this electrostatic latent image is made visible by coloring or developing the charged areas of the noodle medium.

This invention relates to a multi-needle electrode manufacturing device for an electrostatic recording head that moves in the 1s1 stage and plays a superimposed role in forming a high-resolution electrostatic latent image. In order to simplify the image distributing circuit, electrostatic recording heads developed in modern technology have a structure in which a matrix is assembled on the head, but the number of multi-needle electrodes is increasing as the number of multi-needle electrodes becomes higher and higher in order to improve image quality. 7) Manual installation of IJ Fuchs wires with multi-needle electrodes not only increases costs but also causes an increase in incorrect wiring.The purpose of the present invention is to eliminate the above-mentioned drawbacks, In order to improve the image quality of electrostatic recording, we use multi-needle electrodes with sizes 12 to 16 and high I.
Significant cost reductions have been achieved by automating the matrix wiring for the matrix wiring of the recording head, and it is also possible to increase the size of the recording head with high quality and no wiring errors. According to the present invention, a plurality of notched grooves are provided in the upper axial direction of the outer periphery of a hollow cylinder, and approximately equal parts are provided in the notched grooves. a drum having a plurality of suction holes extending through it at intervals; a vacuum generator connected to the hollow hole of the wire-wound drum via a rotary joint to generate suction force in the suction holes; A rotary drive unit that can continuously rotate the winding drum at a constant number of rotations,
a one-turn detector that is linked to one rotation of the winding drum and detects the position of the notch groove of the 4) 1!1 drum; a feeding table that moves at a constant speed in parallel with the winding drum;
a wire rod supply section having a thin wire guide for positioning the thin wire at a position substantially in contact with the IIIF ram, and having a tension change controller for applying a constant tension to the thin wire exclusively supplied;
It is fixed on the feed table and moves in the axial direction of the II wire drum in conjunction with the rotation of the winding drum, and receives the signal from the detected amount of rotation to move the fine wire that is sequentially wound on the drum at equal intervals. Originally, suction ξ is applied to the notch groove of the ram 111F of said volume.
A multi-needle electrode manufacturing apparatus for electrostatic recording is obtained, which is equipped with a laser welding machine that sequentially welds a plurality of thin plate distribution materials. Next, the present invention will be explained in detail using examples. Explain to 0th 1st! g
1 is a schematic diagram showing the circuit configuration of a multi-needle electrode. 01 is a multi-needle electrode arranged at a height of 11f"'e to achieve high-precision image quality. Matrix wiring is performed.

In addition, in order to efficiently charge the recording medium with the multi-needle electrode, the auxiliary electrode shown in 3 is arranged on the same plane as the multi-needle electrode.0 To perform electrostatic recording on the recording medium, Select one of the 1 = ** Ill coupling wiring materials 4 that are commonly connected to a plurality of multi-needle electrodes, and select the auxiliary electrodes 1 to Nll to which the multi-needle electrode corresponding to the recording position belongs. A voltage of ±sso vs. degree is instantaneously applied between the two eyes. This is an actual diagram of a multi-needle electrode manufactured by conventional manual labor. The required number of multi-needle electrode wires S with insulation coating of IiI diameter (LO4■) are arranged in parallel at equal intervals and their tips @a are fixed 8. 7 is a bonding wiring material, which is a multi-needle electrode wire material. 5. The multi-needle electrode wire 5 is divided into N blocks equal to the number of auxiliary electrodes 3, and one wire equal to the number of coupling wiring materials is arranged in each block. When the wires in each block are sequentially given repeating numbers from 1 to n, the wires with the same number are laser welded to the connecting wiring material 7 with the same number from 1 to n, and are electrically connected. has been done.

The coupling wiring member 7 is further connected to a connector 8 at one end thereof, and is connected through the connector 8 to a drive path for applying a voltage between both electrodes. On the other hand, the basic configuration of the conventional electrostatic head shown in FIG. 3 in which matrix wiring is performed manually is the same as that of the device according to the present invention, but the matrix wiring section 9
The wire used for multi-needle electrodes is used as is, and as the wires cross each other, wire cutting accidents are likely to occur during wiring work.
Repairs in the event of wiring errors are also extremely difficult.Figure 4 is an actual diagram of a winding driver μ showing an embodiment of the present invention.

The winding drum 10 is a hollow cylinder, and several cutouts are formed in the axial direction of the winding drum 10. The number of notched grooves is the same as the number n of multi-needle electrodes in one block. Each notch groove 11 is provided with through holes 12 for attaching a vacuum iron with a diameter of ASMS degrees at equal intervals, and the hollow hole 13 of the winding drum is connected to a vacuum source to generate vacuum suction force within the notch. 2
The coupling wiring material 7 shown in the figure is suctioned and fixed in each notch.

FIG. 5 is an external view showing an embodiment of the present invention. OlO is a wire-wound drum connected to a Makabe pump 15 via a rotary joint 14, and a connecting wiring material 7 is vacuum-adsorbed onto the outer periphery of the drum. Copper foil with a thickness of about 0.1 mm and a width of about 3 mm is used as the zero-coupling wiring material. The winding drum 1O is the drive motor 1
6, it is continuously rotated at a constant rotation speed. At that time, the rotation of the winding drum 10 is decelerated by the gear train 17 and transmitted to the feed screw 19 that drives the feed table. Now, the lead of the feed screw! ■, and if the reduction ratio of the gear train 17 is 3,
When the winding drum rotates 166 times, the feed table moves 1 inch. Immediately after insulating the wire for the multi-needle electrode, a constant tension is applied by the cylinder controller 21, and the thin wire is sequentially transferred to the tram axis direction according to the rotation of the winding drum. The wire passes through the kite 22 and is wound on the outer periphery of the scroll drum at equal intervals.

Since the fine guide n is fixed on the feed table 18, it advances by III+ when the winding drum 10 rotates 166 times.

In other words, r'1 is a structure in which 16 thin wires can be arranged at # intervals within 1 m. Of course, it goes without saying that the pitch of the multi-needle electrodes can be set to any desired pitch by combining the reduction ratio of the single-wheel drive 1417 and the leads of the feed screw 19.

If the multi-needle electrode wire is wound around the semi-drum, it will only be wound at intervals, and the matrix wiring for the electrostatic recording head will not be formed. , Matrix Handout 11 m&#! J
G! The laser beam 25 is outputted in pulses from the laser melting mechanism according to the rotation detection and okara signal that detects each part of the plurality of bonded wiring materials 7 attached to the wire 2a, and the wire material is added to the winding drum IO. Each time it is rotated, it is welded to the coupling wiring material 7 and electrically coupled. At that time, for example, 7
The wire 20m of the first rotation is welded to the joining wiring material 7a, the wire 2ob of the next eighth time is welded to the joining wiring material 7b, and so on, the joining wiring material is shifted by one at each rotation and welded, as shown in Fig. 1. Matrix wiring of multi-needle electrodes as shown can be realized, and after winding is completed around the entire circumference of the winding drum, the thin wire is cut in the axial direction of the winding drum, and vacuum suction of the bonded wiring material is stopped. When the multi-needle electrode is removed from the drum and unfolded, a multi-needle electrode for an electrostatic placement head shown in @2@l is formed.

As explained above, according to the present invention, in the production of multi-needle electrodes that aim to increase the density of the multi-needle electrodes to 16 mm in order to improve the image quality of electrostatic recording, It can be manufactured within a short period of time, significantly reducing costs, eliminating incorrect wiring and forming high-quality multi-needle electrodes, as well as large f! Many advantages can be obtained, such as the ability to easily manufacture large multi-needle electrodes for brass devices.
