Abstract

PURPOSE:To make surface treatment of ceramic substrates of various dimention with one piece of rack by easily following up the change, if any, in the sizes of the ceramic substrates and absorbing even the dimensional errors thereof. CONSTITUTION:This rack for surface treatment of the ceramic substrates has two pieces of vertical rods 1, 1 parted from each other at a prescribed spacing, plural pieces of supporting rods 6, 6, 6, 6 which are parted from each other apart prescribed intervals and are transversely installed, holding parts 11, 12 which are mounted to the top and bottom of these supporting rods 6, 6, 6, 6 and hold the ceramic substrates 14 disposed between the supporting rods 6, 6, 6, 6. The supporting rods 6, 6, 6, 6 are respectively fixed movably along the longitudinal direction of the vertical rods 1, 1 and at least either of the holding parts 11, 12 mounted to the top and bottom of the supporting rods 6, 6, 6, 6 are formed by springs.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a rack used for surface-treating a ceramic substrate.

[0002]

2. Description of the Related Art Conventionally, a rack shown in FIG. 5 has been used as a rack used for surface-treating a ceramic substrate such as plating.

That is, in the figure, a and a are vertical rods which are separated from each other by a predetermined distance, and a supported portion for a bus bar is provided on the upper end portion thereof, although not shown. Reference numerals b, b, b, and b denote support rods that are laterally bridged between the vertical rods a and a, and the support rods b, b, b, and b are fixed to the vertical rods a and a. c and c are the above-mentioned supporting rods b, b, b and b, respectively.
It is a holding claw for holding the ceramic substrate d arranged therebetween.

[0004]

However, in the rack shown in FIG. 5, between the support rods b, b, b, b (hence between the holding claws c, c).
Since the interval is constant, only a ceramic substrate with a constant size can be held.

However, since the ceramic substrate shrinks due to firing, it is difficult to keep the dimensions constant.
Therefore, in the surface treatment of the ceramic substrate, it was necessary to prepare a large number of racks having different intervals between the supporting rods b, b, b, b (between the holding claws c).

The present invention has been made to improve the above circumstances, and an object of the present invention is to provide a rack for surface treatment of a ceramic substrate which can freely hold ceramic substrates having different sizes.

[0007]

In order to achieve the above-mentioned object, the present invention has two vertical rods which are spaced apart from each other by a predetermined distance, and a plurality of horizontal rods which are vertically spaced from each other between these vertical rods. In the rack for ceramic substrate surface treatment, which is equipped with supporting rods of (1) and holding portions which are attached to the upper and lower sides of the supporting rods and which hold the ceramic substrates arranged between the supporting rods. Provided is a rack for surface treatment of a ceramic substrate, which is movably fixed along the length direction, and at least one of holding portions attached to the upper and lower sides of a support rod is formed by a spring.

[0008]

According to the present invention, each of the support rods is fixed so as to be movable along the lengthwise direction of the vertical rod. Therefore, even if the size of the ceramic substrate is different, it can be reliably followed. Since at least one of the holding portions attached to the upper and lower sides of the supporting rod is formed of a spring, some dimensional error can be absorbed, and therefore one rack can hold ceramic substrates of various sizes.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In FIG. 1, reference numerals 1 and 1 denote vertical rods, which are arranged at a predetermined distance from each other. The upper end of the horizontal rod 2 is fixed to the horizontal rod 2. The upper ends of both ends of the horizontal rod 2 in the longitudinal direction are supported by the carrier bar 3 on the outside and the supported portion for supporting the rack on the surface treatment tank on the inside. Supporting arms 5 and 5 each having 4 are projected integrally.

Reference numerals 6, 6, 6 and 6 denote support rods which are laterally bridged between the vertical rods 1 and 1 at a predetermined distance from each other, and both ends in the length direction thereof are square frames as shown in FIG. Formed into a
The vertical rods 1, 1 are movably attached to the vertical rods 1, 1 along their lengths so that the vertical rods 1, 1 can be slidably inserted into the frame members 7, 7, and It is fixed at a proper position by inserting a proper fixing tool 9 such as a thumbscrew into the mounting holes 8 formed in the holes 7, 8.

Of the support rods 6, 6, 6, 6, the lower three end faces of the upper support rods 5, 5, 5 are provided with holding recesses 10 on the lower end faces as shown in FIGS. Claw (holding part) 1
1 is projected. In addition, the lower three support rods 6, 6, 6
A substantially inverted U-shaped mounting member 13 for holding a leaf spring (holding portion) 12 is provided on the upper part of the ceramic substrate 14, and the ceramic substrate 14 holds the holding recesses 10 and 10 of the two holding claws 11 and the tip end portion of the leaf spring 12. Is held and fixed by the elastic force of the spring 12.

Since the rack of this embodiment has the above structure, the supporting rods 6, 6, 6, 6 are slid with respect to the vertical rods 1, 1 in accordance with the vertical dimension of the ceramic substrate 14, and the racks are appropriately positioned. By fixing with, ceramic substrates of various sizes 1
It can be applied to 4. In addition, holding the ceramic substrate 13
Since the elastic force of the leaf spring 12 is used, it is firmly held and fixed, and the ceramic substrate 13
Even if there is some dimensional error, it can be reliably absorbed.

The structure of the rack of the present invention is not limited to the above embodiment, but various modifications can be made to the structure of the supporting claws, springs and the like.

[0014]

As described above, according to the present invention,
Even if the size of the ceramic substrate changes, it can be easily followed and the dimensional error can be absorbed, so that the surface of ceramic substrates of various sizes can be treated with one rack.
