Description

Plating Clamps {CLAMP FOR PLATING}

The present invention relates to a clamp for plating.

In general, circuit patterns formed on a thin film circuit board such as a printed circuit board (PCB) are composed of a metal thin film such as gold (Au) or silver (Ag). These thin films are formed by electroplating (electrolytic plating) during the PCB manufacturing process, and the electroplating operation, as is well known, connects a PCB manufacturing substrate, that is, a thin film-like plated body with a negative electrode, and the plating solution of the electroplating bath. (Electrolyte) is connected to the positive electrode (+), and the thin film-like plated body is immersed in the plating solution. According to such an electroplating operation, it is very important to carry out the plating operation in a state where the thin film type plated body is stably held to enable electroplating, and as a device for holding the thin plate type plated body, electroplating operated in the form of tongs Clamps are well known. The electroplating clamp is connected to the jaws (Jaw) having a tip for the conduction is connected to the hinge coupling so that the two jaw pressurization portion is narrowed or opened around the hinge coupling point to energize the edge of the thin film type plated body (通電) It is formed to be able to hold.

As the thickness of the substrate becomes thinner and the thickness and type of the substrate vary, a plating clamp for each substrate thickness is required.

DETAILED DESCRIPTION A plating clamp according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings, and in the following description with reference to the accompanying drawings, the same or corresponding components are given the same reference numerals, and duplicate description thereof will be given. It will be omitted.

1 and 2, the clamp for plating according to an embodiment of the present invention includes a main part 100, a clamping part 200, an elastic part 300, and an elastic adjusting part 400. can do.

A central portion of the main part 100 may be coupled to the clamping part 200 so as to be rotatable. A substrate to be plated is inserted and clamped between one end of the clamping part 200 and one end of the main part 100, and the other end of the main part 100 and the other end of the clamping part 200 are narrowed or far from each other. As a result, the degree of clamping can be adjusted.

In general, rinsing and connecting the substrate with a clamp to apply the current of the substrate, and as the thickness of the substrate has recently become thinner or various kinds of substrates, it has become necessary to correspond to each substrate thickness.

However, in general, since the clamp is integrated with the rinsers, it is inconvenient to replace the clamps and rinsers according to the thickness of the substrate.

In addition, the more the clamp is used, the more the spring tension is lost, and the clamp used for a long time cannot be applied to the thin plate because the elasticity is applied, and there is a disadvantage that it can only be used for the thick plate.

By using an elastic clamping portion 400 for adjusting the elastic force of the elastic portion 300 applied to the plating clamp using a plating clamp according to an embodiment of the present invention to prevent the above problems, product type, output Eliminate equipment constraints and quality problems caused by fluctuations and save money.

The elastic part 300 is formed between the other end of the main part 100 and the other end of the clamping part 200 to provide an elastic force for clamping the substrate.

The elastic part 300 may be formed of a spring to provide an elastic force for clamping the substrate.

One end of the elastic control unit 400 is connected to the elastic unit 300, it may be coupled to a portion of the main portion (100).

As shown in FIG. 1 or 2, one end of the elastic part 300 is coupled to a part of the clamping part 200, and one end of the elastic control part 400 is coupled to the other end of the elastic part 300. The elastic control unit 400 is coupled to the main unit 100.

The elastic control unit 400 is directly connected to the elastic unit 300, one end is coupled to the pressure plate 410 and the pressure plate 410 capable of compressing or releasing the elastic unit 300 to advance or retract the pressure plate 410. It may include a moving unit 420.

At this time, the moving part 420 is formed of a screw, the moving part 420 is screwed to the main part 100, the moving part 420 can move through the rotation of the screw, the moving part 420 is moved As the pressure plate 410 coupled to one end of the moving part 420 is moved forward or backward.

As the pressure plate 410 moves forward or backward, the elastic portion 300 having one end coupled to the pressure plate 410 may be compressed or released.

As the elastic part 300 is compressed or released, the clamping part 200 may rotate, and thus the degree of supporting the substrate may vary.

In the case of a thin plate, the moving part 420 is rotated to advance the pressing plate 410, and as the pressing plate 410 is advanced, the elastic part 300 is compressed to push the other end of the clamping part 200 to clamp the clamping part. The portion directly supporting the thin plate of 200 may be further compressed with the main part 100 to more firmly support the thin plate.

In addition, even when the elastic force of the elastic part 300 is weakened due to long use of the clamp, there is an effect that the elastic force can be improved by advancing the pressure plate 410.

As shown in FIG. 1 or 2, the clamping part 200 according to the exemplary embodiment of the present invention may include a support part 220, a handle part 210, and a coupling part 223.

The support part 220 of the clamping part 200 may directly support the substrate by clamping the substrate, and the handle part 210 may be formed at the other side of the support part 220 supporting the substrate, so that the elastic part 300 may be directly coupled to the support part 220. have.

In addition, the coupling part 223 may allow the clamping part 200 to be rotatably coupled with the main part 100.

At the end of the handle portion 210 is bent to form a first hinge coupling portion 222 for hinge coupling with the coupling portion 223, the substrate is coupled to one end of the support portion 220, the handle portion ( 210 and a second hinge coupling portion 221 for hinge coupling may be formed.

When the handle part 210 is moved away from the main part 100, the first hinge coupling part 222 formed at the end of the handle part 210 may have a coupling part fixed to the main part 100 in the counterclockwise direction. At this time, the end of the handle portion 210 is pressed by the support portion 220, the degree of clamping the substrate of the clamping portion 200 becomes stronger.

On the contrary, when the handle part 210 approaches the main part 100, the first hinge coupling part 222 formed at the end of the handle part 210 has a coupling part fixed to the main part 100 in a clockwise direction. In this case, the support part 220 is moved away from the main part 100 so that the degree of clamping the substrate is weakened.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
