Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board electroplating technology, specifically a fixture structure for horizontal electroplating. Background Technology
[0002] In circuit board manufacturing, electroplating technology not only provides a solid metallic coating but also directly affects the circuit board's performance and quality. Among these techniques, horizontal electroplating and vertical electroplating are two of the most common. Compared to vertical electroplating, horizontal electroplating offers a significant advantage in terms of uniformity. In horizontal electroplating, the circuit board is placed horizontally in the plating tank, with the surface to be plated parallel to the plating solution surface. This results in a more uniform distribution of current across the plated component and a more consistent plating thickness. This not only improves the conductivity of the circuit board but also enhances its reliability and lifespan. However, in horizontal electroplating, the circuit board needs to be clamped in place using fixtures.
[0003] Chinese patent discloses a horizontal electroplating fixture (authorization announcement number CN204550773U). This patented technology introduces an eccentric wheel structure, which makes the originally independent upper and lower clamping plates linked together, thereby realizing the simultaneous opening and clamping of the upper and lower clamping plates. This reduces the probability of board jamming during the clamping and conveying process of the circuit board in electroplating, and greatly improves the production efficiency and product quality of the electroplating equipment. However, during the rotation of the eccentric wheel, it is easy for debris to adhere to the circuit board, causing it to be scrapped. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A fixture structure for horizontal electroplating includes a fixed component and a movable component that matches the fixed component. The bottom end of the fixed component is provided with a lower clamping piece, and the bottom end of the movable component is provided with an upper clamping piece. An insulating sleeve is sleeved on the lower outer sides of the fixed component and the movable component. An upper slider and a lower slider are respectively installed on the upper and lower inner sides of the fixed component and the movable component. A conductive connector is connected to the upper outer side of the fixed component and the movable component near the upper slider. An opening and closing assembly is installed on the top of the movable component. The opening and closing assembly includes an L-shaped fixing block. A bearing is installed on one side of the L-shaped fixing block, and several screws are embedded on the other side of the L-shaped fixing block. A limit groove is formed on the lower side of the L-shaped fixing block near the bearing, and a retaining groove is formed on the lower side of the L-shaped fixing block near the screws.
[0007] As a further embodiment of this utility model: the top of the movable part is embedded in the slot, and a limiting post is fixedly connected to the upper end of one side of the movable part, the limiting post being embedded in the limiting groove.
[0008] As a further embodiment of this utility model: both the lower slider and the upper slider are fixedly connected to the fixing member, and both the lower slider and the upper slider are slidably connected to the moving member.
[0009] As a further embodiment of this utility model: the upper slider includes an I-shaped partition block located between the fixed part and the movable part, and a pad located on the outside of the movable part. The lower end of the I-shaped partition block is fixedly connected to a guide post, and a spring is sleeved on the outside of the guide post. A long screw is provided through the inner sides of the I-shaped partition block and the pad.
[0010] As a further embodiment of this utility model: the upper and lower ends of the inner side of the movable part are respectively provided with an upper strip groove and a lower strip groove, the I-shaped partition block and the pad are located on both sides of the upper strip groove, and the long screw passes through the inner side of the upper strip groove and is fixed to the fixing part.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention utilizes the bearings in the opening and closing assembly to move within the grooves on the plastic block, enabling the moving parts to slide up and down. This allows the upper and lower clamping plates to merge and separate, clamping or releasing the circuit board. This reduces friction and significantly minimizes the generation of debris on the plastic block. Even if debris is generated, it will not fall onto the circuit board and cause it to be scrapped, ensuring electroplating quality and improving the precision of the circuit board. The upper and lower sliders ensure stable up and down movement of the moving parts, thereby achieving reliable clamping. Attached Figure Description

[0021] Please see Figures 1-6 In this embodiment of the present invention, a clamping structure for horizontal electroplating includes a fixing member 1 and a movable member 2 that matches the fixing member 1. A lower clamping piece 4 is provided at the bottom end of the fixing member 1, and an upper clamping piece 3 is provided at the bottom end of the movable member 2. The upper clamping piece 3 and the lower clamping piece 4 can clamp the circuit board horizontally and place it into the electroplating tank for electroplating. An insulating sleeve 5 is fitted onto the lower outer sides of both the fixing member 1 and the movable member 2. The insulating sleeve 5 insulates the lower parts of the fixing member 1 and the movable member 2 to prevent electric shock. An upper slider 7 and a lower slider 6 are respectively installed at the upper and lower inner sides of the fixing member 1 and the movable member 2. The outer sides of the fixing member 1 and the movable member 2 are close to the upper... The upper end of the slider 7 is connected to a conductive connector 10, which connects the conductive connector 10 to an external power source. When the upper clamp 3 and the lower clamp 4 clamp the circuit board, a path is formed between the conductive connector 10, the fixing member 1, the lower clamp 4, the circuit board, the upper clamp 3, the movable member 2, and the external power source. When the circuit board is placed horizontally into the electroplating tank, the electroplating solution can form a plating layer on the circuit board. The top of the movable member 2 is equipped with an opening and closing component 9. The lower slider 6 and the upper slider 7 are both fixedly connected to the fixing member 1, and the lower slider 6 and the upper slider 7 are both slidably connected to the movable member 2, so that the movable member 2 can move up and down to adjust the position of the upper clamp 3 and the lower clamp 4, thereby fixing or loosening the circuit board.
[0022] exist Figure 2 , Figure 3 and Figure 4In the middle, the opening and closing assembly 9 includes an L-shaped fixing block 91. A bearing 93 is installed on one side of the L-shaped fixing block 91, and several screws 95 are embedded on the other side of the L-shaped fixing block 91. A limiting groove 92 is formed on the lower side of the L-shaped fixing block 91 near the bearing 93, and a retaining groove 94 is formed on the lower side of the L-shaped fixing block 91 near the screws 95. Figure 6 As shown, the plastic block 14 is fixedly installed on the external structure, and the bearing 93 is placed in the high-low groove 15 on one side of the plastic block 14. The entire clamping structure is pulled along the high-low groove 15 by an external transmission structure such as a belt or chain. When the bearing 93 reaches the high position in the high-low groove 15, the movable part 2 slides upward, while the fixed part 1 remains stationary in the vertical direction, thus separating the upper clamping plate 3 and the lower clamping plate 4. At this point, the circuit board to be electroplated can be placed between the upper clamping plate 3 and the lower clamping plate 4. When the bearing 93 continues to move to the low position in the high-low groove 15, the movable part 2 slides downward, thus separating the upper clamping plate 3 and the lower clamping plate 4. The clamping plate 3 and the lower clamping plate 4 are combined to clamp the circuit board. The bearing 93 moves within the high and low grooves 15, which reduces friction and greatly reduces the generation of debris on the plastic block 14. Even if debris is generated, it will not fall onto the circuit board and cause it to be scrapped, thus ensuring the electroplating quality. The top of the movable part 2 is embedded in the slot 94, and a limiting post 13 is fixedly connected to the upper end of one side of the movable part 2. The limiting post 13 is embedded in the limiting groove 92. By rotating the screw 95, the screw 95 is pressed against the movable part 2, which can securely install the opening and closing assembly 9 and the movable part 2 together without displacement.
[0023] exist Figure 1 , Figure 2 and Figure 5 In the middle, the upper slider 7 includes an I-shaped partition block 71 located between the fixed part 1 and the movable part 2, and a pad 74 located on the outside of the movable part 2. The lower end of the I-shaped partition block 71 is fixedly connected to a guide post 73, and a spring 72 is sleeved on the outside of the guide post 73. A long screw 75 is provided through the inner sides of the I-shaped partition block 71 and the pad 74. The upper and lower ends of the inner side of the movable part 2 are respectively provided with an upper strip groove 8 and a lower strip groove 11. The I-shaped partition block 71 and the pad 74 are located on both sides of the upper strip groove 8, and the long screw 75 passes through. The inner side of the upper strip groove 8 is fixed to the fixing member 1. A certain distance is maintained between the fixing member 1 and the movable member 2 by the I-shaped separator 71, and the long screw 75 can slide up and down along the upper strip groove 8. Similarly, the screw on the lower slider 6 can also slide along the lower strip groove 11. One end of the movable member 2 is fixedly connected to a support block 12 between the upper strip groove 8 and the lower strip groove 11. A through hole is opened on the inner side of the support block 12, and the lower end of the guide post 73 slides in the through hole. The lower end of the spring 72 is supported on the support block 12. Figure 6As shown, when the bearing 93 moves to the high position in the high and low groove 15, the movable part 2 slides upward, and the support block 12 presses the spring 72 upward, causing the spring 72 to shorten; when the bearing 93 moves to the low position in the high and low groove 15, the spring 72 extends and pushes the support block 12 downward, and the movable part 2 slides downward, which allows the movable part 2 to automatically reset.
