JPH03231102A - Jig for checking deformation of green-sheet holding tool - Google Patents

Abstract

PURPOSE:To shorten checking time, to eliminate personal difference in judgment of pass or fail of the checks and to check the deformed state by using a stage and a roller, and connecting the stage and the roller through a DC power source and a buzzer. CONSTITUTION:The interval between the surface of a stage 1 and a deformation detecting roller 5 is set at the value obtained by adding the thickness of a green-sheet holding tool and the tolerance in changing amount beforehand. The green-sheet holding tool is mounted on the stage 1. Then, the handle of a sliding part 2 is held, and the sliding part 2 is slid from an original-point position toward an operator. When the green-sheet holding tool comes into contact with the roller 5 because of the deformation at this time, the circuit is closed, and a buzzer is sounded. At this time, the operator judges the defect and returns the sliding part 2 to the original point.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for checking deformation of a green sheet holder, and in particular to a green sheet holder that makes it possible to shorten the checking time and eliminate individual differences in measured values. Regarding deformation check jig.

[Conventional technology]

The conventional green sheet holder deformation check involves placing the green sheet holder on a surface plate, fixing an optical displacement sensor to the magnetic holder, moving it directly above the green sheet holder, and measuring the displacement.

Regarding the green sheet holder, for example, Japanese Patent Laid-Open No. 57-20496 can be cited.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration workability or ensuring reliability, and has problems such as time-consuming checks and individual differences in determining whether the checks are good or bad.

The purpose of the present invention is to shorten the checking time, eliminate individual differences in checking quality, and at the same time make it possible to check deformed states that were impossible to check with the prior art.

[Means to solve the problem]

In order to achieve the above objective, we use a stage made of conductive metal that fixes the green sheet holder, and a roller that moves while keeping a constant distance from the surface of this stage. By connecting through the green sheet holder, deformation of the green sheet holder can be detected by a buzzer.

[For production]

The distance between the front surface of the stage and the deformation detection roller is set in advance to a value that is the sum of the thickness of the green sheet holder and the allowable amount of change, and the green sheet holder is placed on the stage. Next, hold the handle of the slide part and slide it toward you from the origin position. At this time, if the green sheet holder comes into contact with the deformation detection roller due to deformation, the circuit is closed and a buzzer sounds. At this point, the operator considers the product to be defective and returns the slide portion to its original position.

With the above operations, it is possible to check the deformation of one green sheet holder in 15 seconds, and the entire surface of the green sheet holder can be checked for deformation, which eliminates individual differences in the quality of the check performed by multiple workers. .

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4.
This will be explained with reference to FIG.

Figure 2 shows the dimensions of the green sheet holder, which is symmetrical to check. The green sheet holder is a thin, frame-shaped object made of a conductive member, and is highly susceptible to deformation. The allowable value of this amount of deformation is set to be 30μ or less.

Figure 1 shows the appearance of the green sheet holder deformation check jig.

This jig consists of stage 1, slide part 2, and base plate 3.
, a DC power supply and a buzzer 4.

The slide section 2 includes a deformation detection roller 5, a roller height adjustment section 6. It is composed of a handle 7.

The stage 1 is attached to the base plate 3 via an insulator, and the deformation detection roller 5 and the stage 1
Both are made of conductive material.

The deformation detection roller 5 is also made of conductive metal.

It is connected to the stage 2 via a DC power source and a buzzer 4, and by adjusting the roller height adjustment section 6, the distance from the surface of the stage 1 can be set.

Figure 3 shows the principle of checking the deformation of a green sheet holder using a single jig. A green sheet holder is set on the stage 1, and the distance between the surface of the stage 1 and the deformation detection roller 5 is set in advance.

Holding the handle 7, the slide portion 2 is slid toward you from the original position. At this time, if the surface of the green sheet holder comes into contact with the deformation detection roller 5 due to deformation, a circuit is closed and a buzzer sounds. This allows the operator to judge whether the product is good or bad.

FIG. 4 shows details of the roller and height adjustment section 7, and FIG. 5 shows a method of adjusting the roller and height.

The roller height adjustment section 7 includes a bearing 8, a positioning bolt 9. Consists of a bracket 10, with positioning bolts 9
By loosening , the bearing 8 can be slid up and down.

The adjustment method is to place two height adjustment gauges 11 on the stage 1, slide the slide part 2 so that the height detection roller 5 is above it, and then tighten the positioning bolts 9 of the left and right height adjustment parts 7. , and push down the deformation detection roller 5. In this state, tighten the positioning bolt 9. The distance between the surface of the stage 1 and the deformation detection roller 5, that is, the thickness of the height adjustment gauge is the thickness of the green sheet holder plus the allowable deformation amount, and is usually 1.31.

Other values can be set by selecting a height adjustment gauge.

According to this embodiment, the entire green sheet holder can be checked continuously by sliding the slide part 2 one time, so that the checking time can be significantly shortened, and when multiple workers are checking, the individual The difference can be eliminated. It is also possible to check deformed states that were impossible to detect with conventional checks.

〔Effect of the invention〕

According to the present invention, it is possible to check the deformation of one green sheet holder in 15 seconds.

This has the effect of significantly shortening the check time.

Furthermore, since the deformation can be accurately checked regardless of the location of the deformation, it has the effect of eliminating individual differences among multiple workers. Furthermore, since this check method detects lifting of the surface of the green sheet holder, any deformation can be detected.
