JPS6054271A - Supplying and joining device of molten solder of minute constant-quantity - Google Patents

Abstract

PURPOSE:To execute exactly and efficiently a solder joining of a minute pattern in various apparatuses by providing a molten solder tank on the upper part of a minute inside diameter cylinder in a heater member, and moving a piston upward and downward against the cylinder. CONSTITUTION:A set of a minute inside diameter cylinder 1 and a piston 2 is provided on the inside of a heater part, a molten solder tank 4 is provided on the upper part of the cylinder 1, and the piston 2 is moved up and down by an operating cylinder. As a result, when the piston 2 is at the top dead center, a minute constant-quantity flows naturally into the upper part in the cylinder 1 by a capillary phenomenon due to a fact that the surface tension is large, and it is held by the tip when the piston 2 descends. This solder is supplied to a substrate or object joining parts, for instance, a parts lead wire 6.

Description

[Detailed Description of the Invention] This invention supplies a minute amount of molten solder to the fine pattern of a board or #i target joining part by the technical principle of layering, thereby saving labor in soldering a single part to a board, etc. 1. Is it related to a micro-quantity molten solder supply bonding device that can be reasonably prepared for zero functions? )ゐ.

Conventionally, in the production of equipment products, etc., bonding work was carried out by welding in small patterns.

Is the worker using the solder feeder? Did you manually check the adjustment of the 5 supply claws by eye? In addition, when working on minute parts, not only is there unevenness in one work, but there is also a drawback that it is rlU during six works.

Seven trowels (1) The present invention has a number of power shortcomings as described above.

By skillfully utilizing the properties of the solder agent, it is possible to supply minute amounts to minute joints in a functional and rational manner, and at the same time, it is possible to accurately, efficiently and The invention of this invention is the development of a compact or micro-quantity molten solder supply device of the folded hand type that can be carried out reliably. The technical principle is the phenomenon that occurs during a short period of time when the solder is in a floating state, and is a phenomenon that is caused by the properties of the molten solder in the extremely short period of time described above.

It is characterized by its principle structure that can be applied to a cylinder-piston set, delicately supplying a minute amount of the molten material in a minute pattern, and at the same time repeating soldering to obtain a large quantity.

The gist of the present invention is c; 5ii, a me-heater for a cylinder and a piston with a small internal diameter is installed inside the member, molten Ng is provided in the upper part of the cylinder, and the cylinder-piston set is connected to an operating cylinder. By lowering the piston, a small amount of molten solder naturally flows into the upper part of the cylinder when the piston is at top dead center due to capillary action caused by the surface tension hole.As the piston descends, it is held at the tip of the molten solder. is supplied to the substrate or the target component to be bonded, and is configured to perform melt bonding.

Next, an explanation will be given using an example of the operating principle and mechanism, which is based on the explanation of the two work sequences shown in FIG.

Considering the first cause trap, (1) Ima minute inner IL cylinder, (
, 2) In the k'i piston, the upper end surface of the fitting part (3) of the piston (2) in the cylinder (l) becomes the guide part. (4t) is the soldering m, (j) is the cleaning nozzle, (6) is the component lead (wire), (a) is when the piston (2) is stopped - the step (b) is t. During inhalation (
Piston top dead center, holding molten MB → (c) is piston (
, 2) Lowering - + (D) #1 supply O junction → (E) Cleans the tip of the piston (J,). → Go to (A).

The operation is based on a technical principle, and it is possible to supply a small amount of molten solder for joining in a functionally rational manner [9%].

Therefore, since the process of manufacturing 2g C1 electronic products, etc., can be carried out using the molten solder in minute patterns, it is highly effective in various types of production. It can be said that

Examples of practical application of the present invention are as follows.

l　Jumper wires on computer board.

2. Feeding feet or solder to minute lands on the board.

8. Excessive pre-solder supply to minute lands.

4. Soldering of the bottom of the four microscopic parts of various eye movements.

11. The present invention is as described above, and compared to the conventional method in which seed fusion bonding of seeds was performed by hand.
'The results of implementing the invention are as shown in Figure 1.

In addition.

Illusion ■, θ, 2φ (3u wire C θ gO1 (3~zaO@Or- Preheating soldering was performed in the order.

Since this invention is as described in "-," is it related to the solder joining of minute parts in each citrus industry? It is rich in four effects and has industrial value in all directions.
