[0046] like Figure 1-Figure 5As shown, a clamp 100 includes a first clamping part and a second clamping part, at least one of which is a conductive clamping part, and a conductive contact 13 and a first sealing member 14 surrounding the conductive contact 13 are provided on the clamping end of the conductive clamping part; in a working state, the clamping end of the first clamping part and the clamping end of the second clamping part respectively abut against two sides of a plated object 200 to clamp the plated object 200; the first sealing member 14 surrounding the conductive contact 13 abuts against one side of the plated object 200 to form a sealed space, and the conductive contact 13 abuts against the conductive point of the plated object 200. The conductive contact 13 is sealed in the sealed space, and the sealed space can isolate the electroplating solution to prevent the electroplating solution from entering the sealed space to electroplate the conductive contact 13 and the conductive point of the plated object 200.
[0047] For example, the clamping end of the first clamping portion is called the first clamping end, and the clamping end of the second clamping portion is called the second clamping end. The first clamping end and the second clamping end can adopt at least one of the following clamping structures:
[0048] The first type of structural clamping: a conductive contact 13 and a first sealing member 14 surrounding the conductive contact 13 are provided on the first clamping end, and an insulating contact is provided on the second clamping end. The insulating contact cooperates with the conductive contact 13 to clamp the plated workpiece 200, the conductive contact 13 is electrically connected to the conductive point of the plated workpiece 200 it abuts against, and the insulating contact is insulated and connected to the plated surface of the plated workpiece 200 it abuts against. Preferably, the abutting points of the conductive contact 13 and the plated workpiece 200 and the abutting points of the insulating contact and the plated workpiece 200 are symmetrical about a first plane, and the first plane is a plane parallel to the plated surface of the plated workpiece 200.
[0049] The second clamping structure: the second clamping end is provided with a conductive contact 13 and a first sealing member 14 surrounding the conductive contact 13, and the first clamping end is provided with an insulating contact. The insulating contact cooperates with the conductive contact 13 to clamp the plated workpiece 200, the conductive contact 13 is electrically connected to the conductive point of the plated workpiece 200 it abuts against, and the insulating contact is insulated and connected to the plated surface of the plated workpiece 200 it abuts against. Preferably, the abutting points of the conductive contact 13 and the plated workpiece 200 and the abutting points of the insulating contact and the plated workpiece 200 are symmetrical about the first plane, and the first plane is a plane parallel to the plated surface of the plated workpiece 200.
[0050] The third clamping structure: the first clamping end and the second clamping end are both provided with a conductive contact 13 and a first sealing member 14 surrounding the conductive contact 13. The conductive contacts 13 on the first clamping end and the second clamping end are respectively referred to as the first conductive contact 13 and the second conductive contact 13. The first conductive contact 13 and the second conductive contact 13 clamp the workpiece 200 to be plated, the first conductive contact 13 is electrically connected to the conductive point of the workpiece 200 to be plated which it abuts, and the second conductive contact 13 is electrically connected to the conductive point of the workpiece 200 to be plated which it abuts. Preferably, the abutting point of the first conductive contact 13 with the workpiece 200 to be plated and the abutting point of the second conductive contact 13 with the workpiece 200 to be plated are symmetrical about a first plane, and the first plane is a plane parallel to the plated surface of the workpiece 200 to be plated.
[0051] The first and second clamping structures are particularly suitable for single-sided electroplating of the object 200 and electroplating with different effects on both sides of the object 200. The third clamping structure is particularly suitable for electroplating with the same effect on both sides of the object 200.
[0052] In a specific example, Figure 2-Figure 3 As shown, the conductive clamping portion includes a clamping seat 12, a first countersunk hole 12a is provided on the top of the clamping seat 12, a first mounting hole 12b is provided on a side wall of the clamping seat 12 facing the plated object 200, the conductive contact 13 is provided in the first mounting hole 12b and partially extends out of the first mounting hole 12b, the first countersunk hole 12a is connected to the first mounting hole 12b, a conductive connector 11 is provided in the first countersunk hole 12a, and one end of the conductive connector 11 is mechanically and electrically connected to the conductive contact 13. The first mounting hole 12b is a countersunk hole, and the first mounting hole 12b is connected to the sealed space, so that the first mounting hole 12b and the conductive contact 13 are both isolated from the plating liquid.
[0053] Preferably, a first mounting hole 12b is provided on the side wall of the clamping seat 12 and passes through the clamping seat 12 transversely. The head of the conductive contact 13 extends out of the first mounting hole 12b and is close to an opening of the plated object 200, and is in a sealed space. The tail of the conductive contact 13 extends out of the first mounting hole 12b and is away from another opening of the plated object 200 or is in the first mounting hole 12b, and the tail of the conductive contact 13 is insulated, for example, coated with Teflon.
[0054] In a specific example, the conductive contact 13 includes a mounting seat and a telescopic member 132, the mounting seat is provided with a second mounting hole 131a, a compressible medium or an elastic member is provided in the second mounting hole 131a, one end of the telescopic member 132 is provided in the second mounting hole 131a and abuts against the compressible medium or the elastic member, and the other end of the telescopic member 132 extends out of the second mounting hole 131a; the telescopic member 132 is slidably connected to the second mounting hole 131a, and the telescopic member 132 is electrically connected to the mounting seat. In the working state, one end of the telescopic member 132 extending out of the second mounting hole 131a abuts against the conductive point of the plated member 200. By abutting the conductive point of the plated member 200 with the telescopic member 132, it is possible to avoid rigid contact between the conductive contact 13 and the plated surface of the plated member 200, thereby damaging the plated member 200.
[0055] In a specific example, the mounting seat includes a first shaft segment 1311, a second shaft segment 1312 and a third shaft segment 1313 connected in sequence. The shaft diameters of the first shaft segment 1311, the second shaft segment 1312 and the second shaft segment 1313 increase in sequence. A first mounting hole 12b is provided on the side wall of the clamping seat 12, which passes through the clamping seat 12 transversely. The hole diameter of the first mounting hole 12b is a variable diameter, which is adapted to the corresponding first shaft segment 1311, the second shaft segment 1312 and the second shaft segment 1313. The third shaft segment 1313 extends out of one opening of the first mounting hole 12b, and the first shaft segment 1311 extends out of the other opening of the first mounting hole 12b; the telescopic member 132 is provided on the first shaft segment 1311. Through the third shaft segment 1313 extending out of one opening of the first mounting hole 12b, the conductive contact 13 can be quickly disassembled and replaced.
[0056] In a specific example, a third mounting hole 131b is arranged around the second shaft section 1312, and a second sealing member 15 is sleeved in the third mounting hole 131b. The second sealing member 15 is an annular ring structure, and the inner ring of the second sealing member 15 abuts against the bottom of the third mounting hole 131b, and the outer ring of the second sealing member 15 abuts against the inner wall of the first mounting hole 12b. The risk of the plating solution entering the sealed space from the first mounting hole 12b can be reduced by the sealing of the second sealing member 15. Preferably, one end of the conductive connector 11 is an annular structure, and one end of the conductive connector 11 is sleeved on the second shaft section 1312.
[0057] In a specific example, a fourth mounting hole 12c is provided on the clamping end of the conductive clamping portion, and the fourth mounting hole 12c is arranged around the second mounting hole 131a and extends out of the opening of the telescopic member 132, and the first sealing member 14 is an annular structure, and the first sealing member 14 is clamped in the fourth mounting hole 12c, and the surface of the first sealing member 14 extends out of the fourth mounting hole 12c.
[0058] In a specific example, when the first clamping portion or the second clamping portion is an insulating clamping portion 20, an elastic abutment 21 is protruding from the clamping end of the insulating clamping portion 20. By the elastic abutment 21 contacting one side of the plated workpiece 200, the insulating clamping portion 20 can be prevented from rigidly contacting one side of the plated workpiece 200, thereby reducing the risk of damage to the plated workpiece 200.
[0059] Preferably, an annular groove 20a is provided on the clamping end of the insulating clamping portion 20, and the elastic abutment member 21 is clamped in the annular groove 20a.
[0060] In a specific example, Figure 8-Figure 9 As shown, a liquid detection member 16 is arranged in the sealed space formed by the first sealing member 14 abutting against one side of the plated member 200, and is used to detect whether there is leakage of electroplating liquid in the sealed space. For example, the liquid detection member 16 includes a color-changing test paper or a color-changing silica gel, etc. When the electroplating liquid enters the sealed space, the color of the color-changing test paper or the color-changing silica gel in contact with the electroplating liquid changes, and then it can be judged that the electroplating liquid enters the sealed space. Specifically, there is a gap between the end of the first mounting hole 12b close to the plated member 200 and the conductive contact 13, which is called a test gap. The clamping seat 12 is provided with a fifth mounting hole 12d, and the fifth mounting hole 12d is connected to the test gap. The liquid detection member 16 is arranged in the fifth mounting hole 12d, and one end of the liquid detection member 16 extends out of the fifth mounting hole 12d. During electroplating, the opening of the fifth mounting hole 12d away from the test gap is located above the liquid level of the electroplating liquid, so that the liquid detection member 16 extending from the opening of the fifth mounting hole 12d away from the test gap remains above the liquid level of the electroplating liquid. If the plating liquid enters the sealed space, the plating liquid will enter the test gap and the fifth mounting hole 12d in sequence, and then contact the liquid detection member 16 in the fifth mounting hole 12d, causing the liquid detection member 16 to change color.
[0061] Example 2
[0062] A plating device adopts the clamp 100 in Example 1 to clamp the workpiece 200 to be plated, so that the workpiece 200 is electrically connected to the negative pole of the electroplating power supply through the clamp 100. The electroplating device also includes a plating tank and an anode component, the anode component is electrically connected to the positive pole of the electroplating power supply, the plating tank is used to contain the electroplating solution, the anode component is arranged in the electroplating solution, and when electroplating, at least the plated surface of the workpiece 200 is located in the electroplating solution and the plated surface is facing the anode component.
[0063] In a specific example, a plurality of fixtures 100 are provided on the same workpiece 200 to form a plurality of power supply points on the workpiece 200. In the event of failure of a single power supply point, electroplating can still be achieved. In addition, different areas on the workpiece 200 can be connected to electricity and plated at the same time, which can improve electroplating efficiency and uniformity.
[0064] In a specific example, each of the clamps 100 has only one conductive clamping part, wherein the conductive clamping parts of some of the clamps 100 are connected to the conductive points on the first surface of the object 200 to be plated, and the conductive clamping parts of the other part of the clamps 100 are connected to the conductive points on the second surface of the object 200 to be plated, and the first surface and the second surface are two opposite surfaces of the object 200 to be plated. Therefore, a first current can be passed through the conductive clamping part connected to the conductive points on the first surface of the object 200 to be plated, and a second current can be passed through the conductive clamping part connected to the conductive points on the second surface of the object 200 to be plated. The first current and the second current are different in magnitude, and electroplating with different electroplating effects on both sides of the object 200 to be plated can be achieved.
[0065] More specifically, there are two electroplating power supplies, the negative pole of one electroplating power supply is connected to the conductive point on the first side of the workpiece 200 through a conductive clamping part of the clamp 100, and the negative pole of the other electroplating power supply is connected to the conductive point on the second side of the workpiece 200 through another conductive clamping part of the clamp 100.
[0066] In a specific example, there are multiple fixtures 100, and all the fixtures 100 are installed on the installation platform 300. Figure 1 , Figure 6-Figure 7 As shown, a plurality of fixtures 100 clamping the same plated object 200 is called a fixture group, and the fixture group includes a plurality of fixtures 100 spaced apart along the front-to-back direction, and a plurality of fixture groups are arranged on the mounting platform 300, and the fixture groups are spaced apart along the left-right direction. Figure 6 In the left and right directions, front refers to the direction perpendicular to the paper surface, and back refers to the direction perpendicular to the paper surface.

[0071] The object to be plated 200 is immersed in the electroplating solution for electroplating. During the electroplating process, the conductive points and the conductive contacts 13 in contact with the conductive points are kept sealed in the sealed space.
[0072] The conductive point and the conductive contact 13 in contact with the conductive point are sealed in a sealed space, and the sealed space can isolate the electroplating solution to prevent the electroplating solution from entering the sealed space to electroplate the conductive contact 13 and the conductive point.
[0073] In a specific example, the conductive contact 13 is made of elastic conductive material or is a retractable component to prevent the conductive contact 13 from damaging the plated object 200 .
[0074] In a specific example, the clamping end of the first clamping part and the clamping end of the second clamping part are respectively abutted against two sides of the workpiece 200 to clamp the workpiece 200, wherein at least one of the first clamping part and the second clamping part is a conductive clamping part, and a conductive contact 13 and a first sealing part 14 surrounding the conductive contact 13 are provided on the clamping end of the conductive clamping part; the first sealing part 14 surrounding the conductive contact 13 abuts against one side of the workpiece 200 to form a sealed space, and the conductive contact 13 abuts against the conductive point of the workpiece 200 to be plated; the workpiece 200 is immersed in the plating solution for electroplating, and during the electroplating process, the conductive point and the conductive contact 13 in contact with the conductive point remain sealed in the sealed space.
