[0041] Embodiment 1
[0042] As Figures 1-5 shown, a fixture 100 includes a first clamping portion and a second clamping portion. At least one of the first clamping portion and the second clamping portion is a conductive clamping portion. A conductive contact 13 is provided at the clamping end of the conductive clamping portion, and a first sealing member 14 is disposed around the conductive contact 13. In the working state, the clamping ends of the first clamping portion and the second clamping portion respectively abut against two sides of the workpiece to be plated 200 to clamp the workpiece to be plated 200. The first sealing member 14 disposed around the conductive contact 13 abuts against one side of the workpiece to be plated 200 to form a sealed space, and the conductive contact 13 abuts against the conductive point of the workpiece to be plated 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 workpiece to be plated 200.
[0043] Exemplarily, the clamping end of the first clamping portion is defined as the first clamping end, and the clamping end of the second clamping portion is defined as the second clamping end. The first clamping end and the second clamping end can at least adopt one of the following clamping structures:
[0044] The first structure clamping: A conductive contact 13 is provided on the first clamping end, and a first seal 14 is disposed around the conductive contact 13. An insulating contact is provided on the second clamping end. The insulating contact cooperates with the conductive contact 13 to clamp the workpiece to be plated 200. The conductive contact 13 is electrically connected to the conductive point of the workpiece to be plated 200 with which it abuts, and the insulating contact is insulatedly connected to the plating surface of the workpiece to be plated 200 with which it abuts. Preferably, the abutting point of the conductive contact 13 and the workpiece to be plated 200 and the abutting point of the insulating contact and the workpiece to be plated 200 are symmetric about a first plane, and the first plane is a plane parallel to the plating surface of the workpiece to be plated 200.
[0045] The second clamping structure: A conductive contact 13 is provided on the second clamping end, and a first seal 14 is disposed around the conductive contact 13. An insulating contact is provided on the first clamping end. The insulating contact cooperates with the conductive contact 13 to clamp the workpiece to be plated 200. The conductive contact 13 is electrically connected to the conductive point of the workpiece to be plated 200 with which it abuts, and the insulating contact is insulatedly connected to the plating surface of the workpiece to be plated 200 with which it abuts. Preferably, the abutting point of the conductive contact 13 and the workpiece to be plated 200 and the abutting point of the insulating contact and the workpiece to be plated 200 are symmetric about a first plane, and the first plane is a plane parallel to the plating surface of the workpiece to be plated 200.
[0046] The third clamping structure: A conductive contact 13 and a first seal 14 disposed around the conductive contact 13 are provided on both the first clamping end and the second clamping end. 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 to be plated 200. The first conductive contact 13 is electrically connected to the conductive point of the workpiece to be plated 200 with which it abuts, and the second conductive contact 13 is electrically connected to the conductive point of the workpiece to be plated 200 with which it abuts. Preferably, the abutting point of the first conductive contact 13 and the workpiece to be plated 200 and the abutting point of the second conductive contact 13 and the workpiece to be plated 200 are symmetric about a first plane, and the first plane is a plane parallel to the plating surface of the workpiece to be plated 200.
[0047] Among them, the first clamping structure and the second clamping structure are particularly applicable to single-sided electroplating of the workpiece to be plated 200 and electroplating with different effects on both sides of the workpiece to be plated 200. The third clamping structure is particularly applicable to electroplating with the same effect on both sides of the workpiece to be plated 200.
[0048] In a specific example, such as Figures 2-3As shown, the conductive clamping portion includes a clamping seat 12. A first counterbore 12a is provided at 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 workpiece to be plated 200. The conductive contact 13 is disposed in the first mounting hole 12b and partially extends out of the first mounting hole 12b. The first counterbore 12a communicates with the first mounting hole 12b. A conductive connecting member 11 is provided in the first counterbore 12a. One end of the conductive connecting member 11 is mechanically connected and electrically connected to the conductive contact 13. The first mounting hole 12b is a counterbore, and the first mounting hole 12b communicates with the sealed space, so that the first mounting hole 12b and the conductive contact 13 are both isolated from the electroplating solution.
[0049] Preferably, the first mounting hole 12b that horizontally penetrates the clamping seat 12 is provided on the side wall of the clamping seat 12. The head of the conductive contact 13 extends out of an opening of the first mounting hole 12b close to the workpiece to be plated 200 and is in the sealed space. The tail of the conductive contact 13 extends out of another opening of the first mounting hole 12b away from the workpiece to be plated 200 or is in the first mounting hole 12b. The tail of the conductive contact 13 is insulated, for example, coated with Teflon.
[0050] In a specific example, the conductive contact 13 includes a mounting seat and a telescopic member 132. A second mounting hole 131a is provided on the mounting seat. A compressible medium or an elastic member is provided in the second mounting hole 131a. One end of the telescopic member 132 is disposed in the second mounting hole 131a and abuts against the compressible medium or the elastic member. 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, the end of the telescopic member 132 that extends out of the second mounting hole 131a abuts against the conductive point of the workpiece to be plated 200. By abutting the telescopic member 132 against the conductive point of the workpiece to be plated 200, rigid contact between the conductive contact 13 and the plated surface of the workpiece to be plated 200 can be avoided, thereby damaging the workpiece to be plated 200.
[0051] In a specific example, the mounting base includes a first shaft section 1311, a second shaft section 1312, and a third shaft section 1313 that are connected in sequence. The shaft diameters of the first shaft section 1311, the second shaft section 1312, and the second shaft section 1313 increase in sequence. A first mounting hole 12b that penetrates the side wall of the clamping seat 12 horizontally is provided on the side wall of the clamping seat 12. The aperture of the first mounting hole 12b is of variable diameter and is adapted to the corresponding first shaft section 1311, second shaft section 1312, and second shaft section 1313. The third shaft section 1313 extends out of one opening of the first mounting hole 12b, and the first shaft section 1311 extends out of the other opening of the first mounting hole 12b; the telescopic member 132 is disposed on the first shaft section 1311. By means of the third shaft section 1313 that extends out of one opening of the first mounting hole 12b, the conductive contact 13 can be quickly disassembled, assembled, and replaced.
[0052] In a specific example, a third mounting hole 131b is provided around the second shaft section 1312 in a circumferential manner. A second sealing member 15 is sleeved in the third mounting hole 131b. The second sealing member 15 is of an annular ring structure. 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. Through the sealing of the second sealing member 15, the risk of the electroplating solution entering the sealed space from the first mounting hole 12b can be reduced. Preferably, one end of the conductive connecting member 11 is of an annular structure, and one end of the conductive connecting member 11 is sleeved on the second shaft section 1312.
[0053] In a specific example, a fourth mounting hole 12c is provided on the clamping end of the conductive clamping portion. The fourth mounting hole 12c is provided around the second mounting hole 131a and extends out of the opening of the telescopic member 132. The first sealing member 14 is of an annular structure. 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.
[0054] In a specific example, when the first clamping portion or the second clamping portion is an insulating clamping portion 20, an elastic abutting member 21 protrudes from the clamping end of the insulating clamping portion 20. By contacting one side of the workpiece to be plated 200 through the elastic abutting member 21, the risk of the insulating clamping portion 20 rigidly contacting one side of the workpiece to be plated 200 can be avoided, thereby reducing the risk of damage to the workpiece to be plated 200.
[0055] Preferably, an annular clamping groove 20a is provided on the clamping end of the insulating clamping portion 20, and the elastic abutting member 21 is clamped in the annular clamping groove 20a.
[0056] In a specific example, such as Figures 8-9As shown, a liquid detection member 16 is provided in the sealed space formed by the first seal 14 against one side of the workpiece to be plated 200, for detecting whether electroplating solution leaks into the sealed space. For example, the liquid detection member 16 includes a color-changing test paper or color-changing silica gel, etc. When electroplating solution enters the sealed space, the color of the color-changing test paper or color-changing silica gel in contact with the electroplating solution changes, and thus it can be determined that electroplating solution has entered the sealed space. Specifically, there is a gap between one end of the first mounting hole 12b close to the workpiece to be plated 200 and the conductive contact 13, which is called a test gap. A fifth mounting hole 12d is formed in the clamping seat 12. The fifth mounting hole 12d communicates with the test gap. The liquid detection member 16 is provided 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 above the liquid level of the electroplating solution, so that the liquid detection member 16 extending out of the opening of the fifth mounting hole 12d away from the test gap is kept above the liquid level of the electroplating solution. If electroplating solution enters the sealed space, the electroplating solution will sequentially enter the test gap and the fifth mounting hole 12d, and then contact the liquid detection member 16 in the fifth mounting hole 12d, causing the liquid detection member 16 to change color.
[0057] Embodiment 2
[0058] An electroplating device uses the fixture 100 in Embodiment 1 to clamp the workpiece to be plated 200, so that the workpiece to be plated 200 is electrically connected to the negative electrode of the electroplating power supply through the fixture 100. The electroplating device further includes an electroplating tank and an anode member. The anode member is electrically connected to the positive electrode of the electroplating power supply. The electroplating tank is used to hold electroplating solution. The anode member is disposed in the electroplating solution. At least the surface to be plated of the workpiece to be plated 200 is in the electroplating solution and the surface to be plated faces the anode member during electroplating.
[0059] In a specific example, a plurality of fixtures 100 are provided on the same workpiece to be plated 200, forming a plurality of power supply points on the workpiece to be plated 200. In the case where a single power supply point fails, electroplating can still be achieved. In addition, different regions on the workpiece to be plated 200 can be simultaneously powered on for electroplating, which can improve electroplating efficiency and electroplating uniformity.
[0060] In a specific example, each of the fixtures 100 has only one conductive clamping portion. Among them, the conductive clamping portions of some of the fixtures 100 are connected to the conductive points on the first surface of the workpiece to be plated 200, and the conductive clamping portions of the other part of the fixtures 100 are connected to the conductive points on the second surface of the workpiece to be plated 200. The first surface and the second surface are two opposite surfaces of the workpiece to be plated 200. Therefore, a first current can be passed through the conductive clamping portion connected to the conductive point on the first surface of the workpiece to be plated 200, and a second current can be passed through the conductive clamping portion connected to the conductive point on the second surface of the workpiece to be plated 200. The magnitudes of the first current and the second current are different, and electroplating with different electroplating effects on both sides of the workpiece to be plated 200 can be achieved.
[0061] More specifically, there are two electroplating power supplies. The negative electrode of one electroplating power supply is connected to the conductive point on the first surface of the workpiece to be plated 200 through the conductive clamping part of part of the fixture 100, and the negative electrode of the other electroplating power supply is connected to the conductive point on the second surface of the workpiece to be plated 200 through the conductive clamping part of the other part of the fixture 100.
[0062] In a specific example, there are multiple fixtures 100, and all the fixtures 100 are installed on the installation platform 300. As Figure 1 、 Figures 6-7 shown, multiple fixtures 100 clamping the same workpiece to be plated 200 are called a fixture group. The fixture group includes multiple fixtures 100 spaced apart in the front-back direction. There are multiple fixture groups provided on the installation platform 300, and the fixture groups are spaced apart in the left-right direction. The left and right here refer to Figure 6 the left-right direction in
