Embodiment Construction

[0024] Hereinafter, a preferred embodiment is given together with the drawings to further illustrate the present invention.

[0025] see Figure 1 to Figure 3 As shown, a device 1 for fixing a plate-shaped object or a sheet-shaped object provided by the first preferred embodiment of the present invention includes:

[0026] A base 10, in this embodiment, is a square hollow frame with a rectangular opening 11 in the center. A recessed area 12 is respectively disposed on the base 10 near the four end corners.

[0027] The base 10 is respectively provided with a guide rail 13, 14 at the bottom end of each of the recessed areas 12. In this embodiment, each guide rail 13, 14 is an oblique elongated groove extending downward and outward respectively, and each has a A first end (upper end) 131 , 141 and a second end (lower end) 132 , 142 . The two upper guide rails 13 are two elongated grooves corresponding to the central longitudinal extension of the base 10 in a mirror state, and...

Abstract

A device for fixing boards and plates contains a base with a slideway at each corner extending downward and outward separately. Every one has a first and a second end, distance between the first ends of the said two slideways is ordered to be smaller than that between the second ends and four flexible mounts having a fixed and a connection parts for each, and each said connection part is connected with the slideway on the base slidely so the flexible mounts are set on the base slidely and move along on the slideway. When these fixed parts fix the boards or plates together, these flexible mounts reach the balance due to the subjects weight.

Description

technical field [0001] The invention relates to a fixing device, in particular to a device for fixing a plate-shaped object or a sheet-shaped object. Background technique [0002] In the process of general printed circuit boards, it is usually necessary to fix the substrate of the printed circuit board on a carrier, and then send the carrier and the substrate into various manufacturing machines, such as electroplating machines, etching machines, etc., for various process steps. [0003] The most basic function of the aforementioned carrier is to firmly fix the substrate. Therefore, we can regard the carrier and the substrate fixed thereon as a rigid body. However, in the manufacturing process, the carrier and the substrate will enter into environments with different temperatures. For example, when the carrier and the substrate will enter into a hot environment, since the specific heat of the substrate and the carrier is not the same ( Generally speaking, the specific heat ...
