Description
Technical Field
The present invention relates to a clamp device for a printed circuit board, and more particularly, to a clamp device for a printed circuit board, which fixes a front side, a rear side, a left side and a right side when a rubber member having elasticity is installed on an inclined surface of a clamp for fixing the printed circuit board, and at the same time, one end and the other end of the clamp are always in a stretched state by a compression spring, thereby preventing a bending and a circuit damage caused by spraying a liquid onto the printed circuit board transferred by a transfer conveyor belt for manufacturing the printed circuit board, minimizing an upper protrusion and a fixing area for fixing the printed circuit board, preventing a puddle phenomenon of the dispersed liquid, and effectively removing, washing and drying the liquid.
Background
Generally, a Printed Circuit Board (PCB) is widely used for all electronic products ranging from home appliances including digital TVs to advanced communication devices as a means for easily connecting a plurality of electronic product devices according to a predetermined frame, and is classified into a general PCB, a module PCB, an assembly PCB, and the like according to applications.
In the process of manufacturing such a printed wiring board, the printed wiring board is transferred in a horizontal direction by a transfer conveyor and subjected to various processes such as washing, drying, exposure, and the like.
In this case, if the printed circuit board sags or is in a bent state due to its own weight and kneading, an accurate process cannot be performed, and therefore, the printed circuit board needs to be maintained in a flat state.
As described above, in order to maintain the printed circuit board flat during the process, the printed circuit board in the process is fixed to the return jig and the printed circuit board manufacturing process is performed in a state where the sagging does not occur.
A typical conventional returning jig is fixed to the upper surface of the returning jig by a pressing plate driven by a hinge in a state where the printed circuit board does not sag.
That is, the printed circuit board may be configured to be clamped at two opposite sides or four opposite sides of the printed circuit board, and the restoring force of the spring may be used for maintenance after the clamping.
However, in the case of using such an elastic body such as a spring, there are problems that foreign substances are generated by repeating mechanical operations, the generated foreign substances adhere to the printed circuit board to cause process defects, and chemicals permeate into the space between the hinges, so that washing and drying cannot be performed, and foreign substances due to magnetic force adhere.
Meanwhile, although not particularly mentioned in the above-mentioned prior art, when the jig performs a mechanical operation, an impact occurs, and by the impact, the alignment state of the returning jig and the printed circuit board is changed, thereby causing a problem that the printed circuit board is mounted in a twisted state or sags.
In view of such a problem, a device for mounting a flexible substrate on a foldback jig is disclosed in patent application No. 10-2013-0040487.
As described above, the conventional apparatus for mounting a flexible substrate by using a folding jig includes: a substrate in a window frame shape; a plurality of magnets embedded in the substrate; a pair of pressing plates which are coupled to the substrate hinge and are formed on the upper portion of the flexible substrate, which is mounted by the attraction of the magnet, on the respective side portions of the side surfaces of the central through hole of the substrate, which are formed in a window frame shape; a hole formed in the substrate, exposing a bottom surface of the pressing plate, and allowing the pressing plate to be rotated upward by inserting an external jig control pin; a returning jig including a plurality of fluid holes that vertically penetrate the substrate and the pressing plate and discharge a fluid for processing the flexible substrate; the fixed frame is used for placing the returning clamp; a movable frame which moves up and down on the lower part of the fixed frame; the jig control pin is fixed to the moving frame, and is inserted through the hole to rotate the pressing plate of the returning jig.
However, the conventional apparatus for mounting a flexible substrate on a general returning jig as described above has a problem that, that is, in the process of clamping the inclined surface of the flexible substrate by the lower clamping protrusion of the pressing plate and the clamping protrusion, the flexible substrate can be prevented from sagging, and particularly, when the etching liquid is sprayed, the flow of the liquid is restricted by the lower clamping protrusion and the upper clamping protrusion of the pressing plate, this causes the kneading (Puddling) phenomenon to be increased, and the portion for fixing the flexible substrate is fixed to the surfaces of the lower clamping projection and the upper clamping projection of the pressing plate, so that it is difficult to remove the chemicals and moisture in the portion fixed in the drying process, thus, a watermark due to non-drying occurs, and at the same time, the space between the hinges cannot be washed and dried due to the penetration of the medicine, and foreign substances due to magnetic force are attached.

one end of the tightening guide rod is screwed into and penetrates the tightening screw hole of the tightening moving member, and is guided by the pair of tightening guide holes.
4. The jig device for printed circuit boards as claimed in claim 1, wherein the left-side placing member and the right-side placing member comprise:
a fixing plate having a plate shape, one end of which is fixed to the upper surfaces of the left side fixing rod and the right side fixing rod at a predetermined interval, and a component mounting hole formed in the plate;
a connecting piece protruding from one end of the fixing plate, wherein the center part of the connecting piece is penetrated so as to penetrate the other ends of the left side fixing rod and the right side fixing rod; and
the left-side placing projection piece and the right-side placing projection piece project from one end of the connecting piece and can be used for placing the left end and the right end of the printed circuit board.
5. The jig device for printed circuit boards as claimed in claim 1, wherein the upper fixing member, the lower fixing member, the left fixing member and the right fixing member comprise:
an upper fixing piece, a lower fixing piece, a left fixing piece and a right fixing piece, one end of each of which is fixed to the bottom surface of the upper end fixing rod and the lower end fixing rod, and the left side fixing rod and the right side fixing rod, respectively;
an upper side bending piece, a lower side bending piece, a left side bending piece and a right side bending piece which are bent obliquely downwards and upwards from one end of the upper side fixing piece, the lower side fixing piece, the left side fixing piece and the right side fixing piece and have elasticity; and
the upper, lower, left and right pressing pieces extend from the ends of the upper, lower, left and right bending pieces, and are used for elastically pressing and fixing the upper, lower, left and right ends of the printed circuit board on which the upper, lower, left and right placing protrusion pieces are placed.
