Description

The present invention relates to a honeycomb work board.

More specifically, the present invention relates to a honeycomb work panel for mounting various measuring devices in a desired combination state in a clean room and performing various kinds of measuring operations of precision devices such as optical devices.

"Prior art" As such a honeycomb working board, generally, a surface member made of a steel plate is joined to both surfaces of an aluminum honeycomb material constituting a main body, and a predetermined interval is provided on an upper surface member. Therefore, a large number of screw holes are provided to penetrate.

"Problems to be Solved by the Invention" By the way, in such a conventional honeycomb working panel, since the main focus is on lightness, the thickness of the upper surface member is required to maintain planar accuracy. Can be done,
The thickness is set as thin as possible so that the measuring instrument can be firmly attached, that is, generally about 5 mm. Therefore,
In most cases, in order to prevent the planar accuracy of the honeycomb working board from being impaired and to facilitate molding, etc., in most cases, after a large number of screw holes are formed in the surface member in advance, the surface member is made of aluminum honeycomb through an adhesive. It is formed by joining to a material.

Further, regarding the length under the neck of the mounting screw for mounting the measuring device, for example, the measuring device is placed in the screw hole where the cell wall forming the cell of the aluminum honeycomb material and the screw hole are located opposite to each other. The length that the cell wall will not be damaged by the mounting screw even when it is mounted, that is, such that the tip of the mounting screw does not protrude from the lower surface of the surface member when the measuring instrument is mounted. The length under the neck is set short.

By the way, since the lower surface of the surface member and the end of the cell wall forming each cell in the aluminum honeycomb material are joined via an adhesive,
Depending on the type of adhesive to be used, for example, whether a two-component resin adhesive or a film adhesive is used, or even when a two-component resin adhesive is used, the lower surface side of the surface member Or to apply to the end side of each cell wall of the aluminum honeycomb material, such as,
Further, depending on the position where the screw hole exists in the aluminum honeycomb material, that is, whether it is located opposite to the cell wall or the hollow portion of the cell, the result to be produced differs, but in most cases, , By heating and pressing at the time of joining,
A part of the adhesive once melted flows into the lower end of at least a part of the screw hole, and the injected adhesive is thereafter hardened and remains as it is in the screw hole. As a result, the thread at the lower end of the screw hole may be filled up with the adhesive over a considerable height.

Therefore, when mounting the measuring device using such a screw hole, the tip of the threaded portion projects from the lower surface of the surface member in a state where the length under the neck of the mounting screw is firmly attached to the measuring device. When the mounting screw is screwed into the screw hole, the adhesive that has adhered to the screw hole or the like is scraped off when the mounting screw is screwed in spite of the setting of the length. Most of the powdered adhesive that has been scraped falls into the cell and stops as it is.

By the way, in a clean room, the positive pressure inside the room is usually about 1.
In addition to being controlled at 4 atmospheres, the temperature, humidity, etc. are also controlled to maintain a predetermined state at all times.

Therefore, in such a clean room, when performing various measurement work of precision equipment using a honeycomb work board, for example, a powdery adhesive or the like is present in a stopped state in the cells of the honeycomb work board. In such cases, the powdery adhesives, etc., which had existed in the cell until now, flew up due to the convection of air in the clean room, and when vibrations occurred in the honeycomb work board, etc. May be scattered into the clean room via the screw holes located in communication with the clean room. If powdery adhesive or the like is scattered, the cleanliness of the clean room will be reduced, the function of the clean room will be impaired, and the measurement equipment and precision equipment will be soiled. It was pointed out.

Therefore, in order to solve the above-mentioned problems, when the measuring instrument is firmly attached, for example, a screw thread located at the lower end of the screw hole used for the attachment adheres over a considerable height. Even if it is buried with an agent, a surface member having a thickness that does not cause a situation in which the tip of the mounting screw comes into contact with the adhered adhesive is used. A screw hole that has a depth such that the tip of the mounting screw does not come into contact with it when the measuring device is mounted with the screw hole or when the measuring device is mounted with the mounting screw, and is opened only on the upper surface side of the surface member The honeycomb work board provided with the was tried. However, in such a honeycomb working panel, even when the honeycomb working panel is used in a clean room, there is no occurrence of deteriorating the function of the clean room, but in any case, the weight of the surface member is significantly increased. Has the disadvantage that the light weight that is the main focus of
In particular, in the latter case, there is a problem in that screw hole processing is troublesome and costly.

The present invention has been made in view of the above circumstances, and has as its object to hardly impair the light weight, which is the main purpose of the honeycomb work board, and to use the honeycomb work board even in a clean room. An object of the present invention is to provide a honeycomb working panel that does not lower the function of a clean room and that can be easily formed.

"Means for Solving the Problems" The present invention has been made to achieve the above object, and the technical solutions thereof are as follows.

The honeycomb working panel according to the present invention is used for performing various types of measuring instruments in a clean room, thereby performing a precise measuring operation of a precision instrument such as an optical instrument, and a planar assembly of hollow columnar cells. And a surface member respectively joined to end faces of cells above and below the honeycomb material.

The upper surface member is made of a metal plate having a predetermined thickness provided with a large number of screw holes penetrating therethrough at a predetermined interval. There is a relationship in which mounting screws for mounting the equipment are screwed.

The upper surface member and the honeycomb material are joined via a cloth body impregnated with an adhesive or the like. In the bonding, part of the adhesive contained in the cloth-like body interposed between the upper surface member and the honeycomb material is exuded by heat and pressure, and is adhered and cured. It is done by.

Further, a part of the adhesive contained in the cloth-like material exudes due to the heating and pressing, flows into the lower end of each of the screw holes of the upper surface member, hardens, and becomes thinner. Forming a layer. Accordingly, the thickness of the upper surface member is set so that the tip of the mounting screw screwed into the screw hole is slightly spaced from the adhesive layer and is not scraped off. It has been set up.

At the same time, the adhesive contained in the cloth is cured as it is after the heating and pressurization, so that the cloth is simultaneously cured. Thus, the lower surface of each screw hole of the upper surface member is closed by the cloth-like body cured by the adhesive.

[Operation] The present invention comprises the above means, and operates as follows.

That is, the honeycomb work board according to the present invention, the upper surface member thereof is formed of a metal plate having a predetermined thickness provided with a large number of screw holes penetrating at predetermined intervals, and The upper surface member and the honeycomb material are:
It is joined via a cloth-like body impregnated with an adhesive or the like.

Therefore, when the upper surface member is joined to the honeycomb material, by heating and applying pressure, a part of the adhesive contained in the cloth-like material interposed therebetween is completely removed from the surface of the cloth-like material. Oozes uniformly and almost uniformly. Then, the exuded adhesive adheres substantially uniformly to the entire lower surface of the surface member, and also flows into the lower end portions of the screw holes by substantially the same amount.

Next, by cooling while maintaining the pressurized state, the adhesive is cured to adhere to the oozing lower surface, and the upper surface member is bonded by the adhesive to the honeycomb through the cloth-like body containing the adhesive. An adhesive layer is formed in the lower end of each screw hole by the adhesive that has been joined to the material and that has flowed into the lower end of each screw hole.

Note that, by curing the adhesive, the cloth body containing the adhesive is simultaneously cured. Thus, the upper surface member is firmly joined to the honeycomb material.

By the way, the adhesive layer formed in the lower end portion of each screw hole is partially heated and pressurized when joining the upper surface member when a part of the adhesive previously contained by impregnation or the like in the cloth-like body. Thus, the entire surface of the cloth-like body is substantially uniformly oozed out and formed by an adhesive that flows into each screw hole by an approximately equal amount, so that the thicknesses thereof are all substantially the same, and Conventionally, when the thickness of the adhesive layer is, for example, used by directly applying approximately the same amount of a two-component resin adhesive to one of the upper surface member or the honeycomb material, sometimes, A part of the adhesive flows into some of the screw holes and adheres thereto, and the height of the adhered adhesive in a case where a thread at the lower end portion is buried over a considerable height or the like occurs. Its thickness is extremely thin.

Therefore, a surface member having a predetermined thickness, that is, the thickness of the surface member is the same as that of a conventional mounting screw in which the length under the neck is set as short as possible so that the measuring instrument can be firmly attached, When using the mounting screws with the same lower length, it is necessary to set the thickness of the upper surface member of a conventional general honeycomb work board to be slightly larger than the thickness of the adhesive layer. However, since the thickness of the formed adhesive layer is extremely thin, the thickness is slightly increased.

Also, the weight of the cloth-like body interposed between the surface member and the honeycomb material is different from that of a metal plate or the like, so that this honeycomb working board is slightly heavier than a conventional general honeycomb working board. Although it increases, it is extremely light when compared with the conventional improved honeycomb work board.

In addition, since the screw holes formed in the surface plate can be provided in advance through the surface plate, the molding of the surface member is easy.

Furthermore, this honeycomb work board has a lower surface of the screw hole of the surface member closed by a cloth-like body cured by an adhesive, and the mounting device can be mounted even when a measuring device is mounted using any of the screw holes. There is no risk that the adhesive forming the adhesive layer will be scraped off by the screw.
Therefore, even when such a honeycomb working panel is used in a clean room, the function of the clean room is not impaired.

"Example" Hereinafter, the present invention will be described based on an example shown in the drawings.

FIG. 1 is a longitudinal sectional view of a main part of the honeycomb working board, and FIG. 2 is a partially cutaway perspective view of the honeycomb working board.

 First, the configuration and the like will be described.

Reference numeral 1 denotes a honeycomb work board, and the honeycomb work board 1
Is an aluminum honeycomb material 2 formed of a planar assembly of hollow columnar cells 3 and upper and lower cells 3 of the aluminum honeycomb material 2.
And surface members 5 and 6 respectively joined to the end surfaces of the respective members.

To describe these in detail, first, the aluminum honeycomb material 2 constituting the main body portion is made of a foil-shaped aluminum material as a base material, and a predetermined number of the base materials are adhered to each other in a predetermined positional relationship, and are laminated. This is formed by expanding the cell in the direction of the attachment, and is formed of a planar aggregate of substantially regular hexagonal hollow columnar cells 3 having a predetermined cell size and height formed by the cell walls 4, and is lightweight. It is excellent in strength, strength, and planar accuracy.

Reference numeral 5 denotes a glass cloth 8 as a cloth-like body in which an appropriate amount of a liquid adhesive 9 is previously impregnated into the upper end surface of the cell 3 in the aluminum honeycomb material 2, that is, the glass cloth 8 is impregnated with the adhesive 9. In this state, the adhesive 9 included in the glass cloth 8 is impregnated with the adhesive 9 in such an amount that the adhesive 9 contained in the glass cloth 8 can be maintained without dripping. The upper surface member 5 is formed of a stainless steel plate having a large number of screw holes 7 penetrating therethrough at predetermined intervals over substantially the entire surface thereof. Is formed, the thickness of which is a predetermined thickness, that is,
In the mounting hole 13a drilled in the mounting edge 13 of the measuring device 12,
As long as the measuring device 12 can be firmly attached, the mounting screw 11 whose length under the neck 1 is set short is inserted and screwed into the screw hole 7 provided in the surface member 5 to measure. When the equipment 12 is firmly attached to the surface member 5, the tip of the attachment screw 11 is attached to an adhesive layer 10, which will be described later, that is,
Surface member 5 via glass cloth 8 containing adhesive 9
When bonding to the aluminum honeycomb material 2, in the bonding process, a part of the adhesive 9 contained in the glass cloth 8 oozes out from the surface of the glass cloth 8 substantially and uniformly by heating and pressing, The exuded adhesive 9 is applied to the surface member 5.
Is adhered to the lower surface of the screw hole, flows into each screw hole 7, and after curing, is located at a slight distance from the adhesive layer 10 formed by the adhesive 9 flowing into each screw hole 7. It is set to the thickness that is possible.

The glass cloth 8 used in this embodiment
With regard to the type and the like, the thickness of the adhesive layer 10 formed in each screw hole 7 can be made thinner as the weave is denser and the thickness thereof is smaller. In other words, the more the glass cloth 8 is used, the thinner the surface member 5 can be set.

In the above-described embodiment, the configuration in which the glass cloth 8 impregnated with the adhesive 9 is used for joining the surface member 5 and the aluminum honeycomb material 2 has been described.
Regarding the means for including the adhesive 9 in the glass cloth 8,
For example, the adhesive 9 may be included in the glass cloth 8 by application.

By the way, as for the glass cloth 8 containing the adhesive 9, the adhesive 9 may be used in an uncured state, but the glass cloth 8 containing the adhesive 9 by impregnation or the like is once used.
It may be used after heating at an appropriate temperature to obtain a semi-cured state. When used after the semi-cured state, the glass cloth 8 and the like can be easily handled and set.

The cloth used is not limited to the glass cloth 8, but may be, for example, a woven cloth or a non-woven cloth of a chemical fiber or the like.

Reference numeral 6 denotes a surface member made of a metal plate joined to the end surface of the cell 3 on the lower side of the aluminum honeycomb material 2.
It is joined to the aluminum honeycomb material 2 via an adhesive 14 previously applied to the entire joining surface of the surface member 6 by coating or the like.

Reference numeral 15 denotes a side frame made of a metal plate joined to a side surface of the aluminum honeycomb material 2 or the like.

 The honeycomb work board 1 is configured as described above.

 Next, the operation and the like will be described.

The honeycomb working board 1 is made of a stainless steel plate having a predetermined thickness and having a large number of screw holes 7 penetrating therethrough at predetermined intervals and joined to an upper side of an aluminum honeycomb material 2 constituting a main body. Are joined via a cloth such as a glass cloth 8 impregnated with an appropriate amount of a liquid adhesive 9 by impregnation or the like.

Therefore, the upper surface member 5 is attached to the aluminum honeycomb material 2.
When bonding is performed, a part of the adhesive 9 included in the glass cloth 8 or the like interposed between the aluminum honeycomb material 2 and the surface member 5 is partially The exuded adhesive 9 adheres substantially uniformly to the entire lower surface of the surface member 5, and flows into the lower end portion of each screw hole 7 by substantially the same amount. Next, by cooling while maintaining the pressurized state, the adhesive 9 is cured, and the adhesive 9 adhered to the exuded lower surface causes the surface member 5 to remove the glass cloth 8 or the like containing the adhesive 9. The adhesive 9 is joined to the aluminum honeycomb material 2 through
An adhesive layer 10 is formed in the lower end of each screw hole 7.

In addition, the glass cloth 8 containing the adhesive 9 is simultaneously cured by the curing of the adhesive 9. Thus, the surface member 5 is firmly joined to the aluminum honeycomb material 2.

By the way, the adhesive layer 10 formed in the lower end portion of each screw hole 7 is configured such that a part of the adhesive 9 previously contained in the glass cloth 8 or the like by impregnation or the like is heated during bonding of the surface member 5. Since it is formed by the adhesive 9 which has oozed out from the surface of the glass cloth 8 and the like by the pressurization, the screw holes are slightly different depending on the thickness of the glass cloth 8 and the density of the texture. The thickness of the adhesive layer 10 formed in each of the adhesive layers 7 is substantially the same, and the thickness of the adhesive layer 10 is conventionally, for example, approximately the same amount of the two-component resin adhesive on the surface When used by directly applying to any one of the joining surface of the member or the cell end surface of the aluminum honeycomb material, sometimes, a part of the adhesive is used.
The thickness is smaller than the height of the adhered adhesive when there is a situation such as flowing into some of the screw holes and adhering, and the thread at the lower end is buried over a considerable height. It is extremely thin.

Therefore, the upper surface member 5 having a predetermined thickness, that is, the thickness of the surface member 5 is set to be as short as possible under the neck 1 as long as the measuring device 12 can be firmly attached. The mounting screw 11 has the same length 1 under the neck as the mounting screw.
When using, the thickness of the upper surface member in the conventional general honeycomb work board, it is necessary to set the thickness slightly thicker than the thickness of the adhesive layer 10, but the adhesive layer 10 Is formed by the adhesive 9 oozing out of the glass cloth 8 or the like at the time of joining the surface member 5, the thickness thereof is extremely small. Therefore, the increase in the thickness of the surface member 5 is small.

Further, since the cloth-like body such as the glass cloth 8 interposed between the surface member 5 and the aluminum honeycomb material 2 is lighter in weight than a metal plate or the like, the honeycomb work board 1 is a conventional general-purpose work board 1. Although the weight is slightly increased as compared with the honeycomb working board, it is extremely light as compared with the conventional improved honeycomb working board.

Further, since the screw holes 7 formed in the surface member 5 can be provided in advance by penetrating, the molding of the surface member 5 is easy.

Further, in the honeycomb working board 1, the lower surface of the screw hole 7 in the surface member 5 is closed by a glass cloth 8 or the like which is hardened by hardening of the included adhesive 9, and any of the screw holes 7 is closed. Even when the measuring instrument 12 is mounted by utilizing the mounting screw 11, there is no possibility that the adhesive 9 forming the adhesive layer 10 is scraped off by the mounting screw 11. Therefore, even when the honeycomb working board 1 is used in a clean room, the function of the clean room is not impaired.

 The above is the description of the operation and the like.

"Effect of the Invention" The honeycomb working board according to the present invention, as described in detail above,
The following effects are exhibited by the fact that the upper surface member of the honeycomb working board is joined to the honeycomb material via a cloth-like body impregnated with an adhesive or the like.

In particular, the upper surface member and the honeycomb material are joined based on the exudation of the adhesive contained in the cloth-like body, and flow into the lower ends of the screw holes of the surface member based on such exudation. The thickness of the upper surface member is set so that the tips of the mounting screws to be screwed are spaced apart from the formed adhesive layer, and furthermore, the cloth is cured by the adhesive. Since the lower surface of each screw hole of the upper surface member is closed, the following effects are exhibited.

In other words, when this honeycomb working panel is used in a clean room, its weight is inevitably slightly heavier than that of a conventional general honeycomb working panel, which may impair the functions of the clean room. Even when used in the above, it is extremely lightweight compared to the conventional improved honeycomb work board which does not have any risk of impairing the function of the clean room, etc., so that the lightness which is the main purpose of the honeycomb work board is impaired. However, even when used in a clean room, precise measurement work and the like can be performed without deteriorating the functions and the like of the clean room, and the molding is easy.

As described above, the effects exhibited by the present invention are remarkably large, for example, the problems existing in this type of conventional example are eliminated.
