Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lead wire assembling device for arranging and assembling one or more lead wires one at a time at predetermined positions, and in particular, the present invention relates to a lead wire assembling device for arranging and assembling one or more lead wires one by one at predetermined positions. The present invention relates to a device suitable for use in inserting one hole into each small hole arranged in a suitable number on the top.

In the manufacturing process of glass seal type diodes,
An appropriate number of lead wires may be arranged and inserted into each of the small holes provided on the magazine plate. Conventionally,
In such a case, as shown in FIGS. 1 and 2, the lead wire case 2 is divided into an appropriate number of compartments 2a corresponding to each small hole 3a on the magazine plate 3, and the lower surface of each compartment is With a plurality of lead wires 1 accommodated in each of the compartments 2a, the lead wire case 2 is stacked on the magazine plate 3, and the case 2 is opened with a wooden hammer. Means for applying appropriate vibration and shock to each lead wire by hitting, etc., and naturally falling one lead wire 1 into each small hole 3a on the magazine plate 3 through the insertion hole 2b of the case, and arranging it in alignment. was being carried out. However, with this conventional method, it is necessary to apply appropriate vibrations and shocks, and to confirm that one lead wire has been inserted into every small hole, so it requires the work of a skilled person. Therefore, it is difficult to automate, is not suitable for mass production, and not only is work efficiency and productivity poor, but also the lead wires may accidentally fall out of the insertion hole of the case when the lead wire case is moved, etc., and be damaged. The disadvantage was that many accidents occurred and the yield of materials decreased.

An object of the present invention is to eliminate the above-mentioned drawbacks, and to provide a lead wire assembling device that can easily automate the lead wire assembling work without requiring any skill, and that can prevent the lead wire from falling by itself. be.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 3 showing one embodiment of the present invention, the lead wire case 2 has an appropriate number of compartments 2 corresponding to each small hole 3a on the magazine plate 3.
The lower surface of each compartment 2a is closed. The case 2 can be placed on a vibration table 5 that is vibrated by an arbitrary vibration means, and a rectangular plate-shaped lead wire chuck 4 can be placed on the case 2. In the height direction of this lead wire chuck 4, there is a storage chamber 8 having a space that can accommodate one lead wire 1 with a margin.
A predetermined number of housing chambers 8 are formed parallel to each other in correspondence with each compartment 2a partitioned by the lead wire case 2, and an insertion hole 8a opening in the lower surface of the lead wire chuck 4 is provided at the lower end of the storage chamber 8. Each is connected. Each of the insertion holes 8a has an inner diameter that allows only one lead wire 1 to be inserted therethrough. A suction case 9 that forms a suction chamber 9a that can cover all the storage chambers 8 is connected to the lead wire chuck 4.

Each accommodation chamber 8 is closed by a closing plate 10 attached to the top surface of the lead wire chuck 4. As shown in FIG.
A suction chamber 9a is formed by making small holes 8c in each of the holes 8c.
These small holes 8c are connected to the lead wire 1.
It has an inner diameter that can prevent insertion of. A predetermined number of electromagnets 6 are provided in the suction chamber 9a, corresponding to the upper part of each of the storage chambers 8. A vacuum pump 7 is used as a means to create a negative pressure state. The operation of the lead wire assembling device according to the above configuration will be explained.

A large number of approximately the same number of lead wires are stored in each compartment 2a of the lead wire case 2 in advance, and the case 2 is placed on the vibration table 5, and the lead wire chuck 4 is placed on the case 2.
Overlap. Continued. Then, start the vacuum pump 7 and open the suction chamber 9.
a, the inside of each accommodation chamber 8 of the lead wire chuck 4 is brought into a negative pressure state, each electromagnet 6 is made into an excited state, and the vibrating table 5 is vibrated to cause each compartment 2 of the lead wire case 2 to be in a negative pressure state.
Create a moderate vibration state on lead wire 1 in a. Forbidden. As a result, one of the lead wires 1 in each compartment 2a of the lead wire case 2 is sucked by the negative pressure of the storage chamber 8 of the lead wire chuck 4, and the insertion hole allows only one lead wire to pass through. They are sucked up into the storage chamber 8 through the chamber 8a, come into contact with the closing plate 10 within the chamber 8, and are reliably attracted and held by the magnetic force of the electromagnet 6. At this time, the height at which the lead wire 1 is sucked up by the suction force of the negative pressure in the storage chamber 8 is about level 8b near the end of the insertion hole 8a, and the lead wire 1 is pulled upward from the level 8b by the electromagnetic force of the electromagnet 6. It will be done. Since the accommodation chamber 8 has ample space, even a bent lead wire 1 can be accommodated. In this way, any detection means (for example, detection means using a phototube,
Once confirmed by visual observation, etc., the lead wire chuck is automatically or manually removed from the magazine plate 3 by any transfer means (e.g., conveyor, magic hand device, or human labor). 1 and 2), and align each storage chamber 8 of the lead wire chuck 4 with each small hole 3a on the magazine plate 3. During this time, lead wire 1
is firmly held by the suction force of the negative pressure in the storage chamber 8 and the electromagnetic force of the electromagnet 6, so the insertion hole 8a
There is no risk of the product falling due to its own weight. After that, the vacuum pump 7 brings the storage chamber 8 into a negative pressure state, and the electromagnet 6
When the excitation state of each of the lead wires 1 is released, the lead wires 1 in each storage chamber 8 are released from the "holding" state and fall under their own weight into the predetermined small holes 3a facing each other in the magazine plate 3. At this time, the lead wires 1 When the length and the height from the upper end of the storage chamber 8 to the lower end of the insertion hole 8a are set approximately equal, the lower end of the lead wire 1 is inserted into the small hole of the magazine plate.
Since the lead wire 1 is located directly above the hole 3a, the lead wire 1 can fall into the small hole 3a very smoothly. As explained above, according to the present invention, each lead wire is sucked up and held by suction in each accommodation chamber of the lead wire chuck through the insertion hole that allows only a single insertion by the negative pressure of the suction means. As with the conventional example mentioned above, automation can be easily achieved without requiring the labor of particularly skilled people, and since the lead wires are held by suction, there is no need to worry about the lead wires being moved while the lead wire chuck is being transferred. There is no risk of the lead wire falling off due to its own weight, and damage to the lead wire due to falling under its own weight, which is the case in the conventional example, can be prevented.

Therefore, work efficiency and productivity are improved, and manufacturing yields are also improved. Furthermore, if the volume of the storage chamber of the lead wire chuck is configured to have a sufficient capacity for the lead wire to be accommodated, even if the lead wire is bent or curved to some extent, it can be accommodated, and the lead wire can be shaped into a straight line. There is no need for correction, and it can greatly contribute to improving the productivity of the entire manufacturing process. Furthermore, if a magnet is provided above each accommodation chamber of the lead wire chuck, the action of suctioning and suctioning and holding the lead wire by the suction means can be reinforced, and the holding state becomes more reliable.

Each storage chamber of the lead wire chuck is configured to communicate with the fluid means by forming a small hole at the upper end of each storage chamber, forming a suction chamber that covers the entire small hole, and connecting the suction chamber with a vacuum pump. If a structure in which the magnets are connected to each other is adopted, it is possible to obtain a structure in which all the storage chambers are brought into a negative pressure state at the same time with a simple structure, and a suitable storage space can be obtained when the magnet is provided. In the above embodiment, a case was described in which a suitable number of lead wires were arranged and inserted into each small hole appropriately arranged on the magazine plate in the manufacturing process of a glass seal type diode. The present invention is applicable not only to this case but also to other electronic component manufacturing processes, wiring work, etc.

Further, in the embodiment, the case where an electromagnet is used has been described, but it is possible to use a permanent magnet such as ferrite as the magnet. When a permanent magnet is used, it is preferable that the permanent magnet be provided so as to be able to move toward and away from the housing chamber of the lead wire chuck, and attract and release the lead wire by approaching and detaching the permanent magnet. Incidentally, even if the lead wire is made of a non-magnetic material, the present invention is applicable because the suction force generated by the negative pressure in the storage chamber can sufficiently suck up and hold the lead wire without using a magnet. be. In the above embodiment, a case was described in which a suction chamber was provided to create a negative pressure state in the accommodation chamber of the lead wire chuck. This invention can also be realized by a configuration in which the vibrators are connected to each other, a configuration in which a lead wire chuck is provided with a flow path that communicates with each storage chamber, and the present invention can be modified in various other ways.
