Description

Technical Field

[0001] This utility model relates to an electroplating apparatus, and more particularly, to a horizontal swing-type electroplating apparatus. Background Technology

[0002] Electroplating of circuit boards is a crucial step in the manufacturing process, and its quality directly affects the performance of the final product. To improve the uniformity of electroplating, various types of electroplating equipment have emerged in existing technologies. Among them, electroplating tanks employing oscillating or reciprocating motion are widely used, aiming to enhance the contact and mass transfer efficiency between the electroplating solution and the circuit board through relative motion.

[0003] Chinese patent CN207793467U discloses a novel swing-type electroplating tank for circuit boards. The device includes a frame with an electroplating rack mounted on it. The lower part of the frame supports the electroplating tank via reinforcing beams, a fixing plate, and a slide rail. A slider at the bottom of the electroplating tank engages with the slide rail, allowing the tank to move in a specific direction. To achieve the swinging motion of the electroplating tank, a drive device is installed on one side of the tank, connected to the side wall via a connecting rod, driving the tank to reciprocate along the slide rail. The electroplating rack has clamps for placing an electroplating basket, which is positioned above the electroplating tank and is immersed in the electroplating solution as it rises and falls with the rack during the electroplating process.

[0004] During use, the lifting mechanism controls the immersion of the electroplating basket carrying the circuit board into the electroplating tank. The drive unit is activated, and the electroplating tank is driven to swing back and forth through the connecting rod, thereby promoting the flow of the electroplating solution in the electroplating basket and ensuring that the electroplating solution makes full and uniform contact with the circuit board.

[0005] However, the aforementioned existing technologies have certain limitations. To ensure the electroplating effect, the oscillating motion of each electroplating tank typically requires an independent drive device. Considering that in actual production, to improve efficiency, multiple electroplating baskets and corresponding electroplating tanks often need to be processed simultaneously on a single electroplating rack, this means that multiple drive devices need to be installed under the same electroplating rack. This design, with one drive device per electroplating tank, significantly increases the complexity of the equipment and manufacturing costs, becoming a disadvantageous factor restricting further improvement in production efficiency and reduction in costs. Therefore, the industry still needs an electroplating device that can achieve synchronous oscillation of multiple electroplating tanks more efficiently and economically. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a horizontal swing electroplating device to reduce production costs.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a horizontal swing electroplating device, including a fixed frame and an electroplating rack, wherein the electroplating rack spans the fixed frame and both ends of the electroplating rack are slidably connected to the fixed frame, a support plate for hanging a hanging rack is fixedly connected to the electroplating rack, a power motor is connected to the fixed frame, a power wheel is fixedly connected to the power shaft of the power motor, a first rack and a second rack are fixedly connected to the end of the electroplating rack, and a power tooth is fixedly connected to the outer wall of the power wheel. After the power wheel rotates, it engages the power tooth with the first rack or with the second rack to make the electroplating rack reciprocate along its own length direction.

[0008] To achieve the above technical solution, multiple hangers are suspended on a support plate and arranged along the length of the support plate. When the power motor is started, the power wheel on its power shaft rotates accordingly. The power teeth on the outer wall of the power wheel periodically mesh with the first or second rack, converting the rotational motion of the power wheel into the horizontal reciprocating movement of the electroplating rack along its length. Therefore, the reciprocating movement of the electroplating rack drives all hangers and the electroplating products on the hangers to reciprocate synchronously, thereby effectively promoting the flow and mass transfer of the electroplating solution, ensuring full and uniform contact between the electroplating solution and the electroplating products, improving the uniformity and efficiency of the electroplating effect, and at the same time, only one drive motor is needed to realize the synchronous processing of multiple workpieces, reducing the complexity and cost of the equipment.

[0009] In a preferred embodiment of this utility model, a slide rail is fixedly connected to the fixing frame, and a slider is fixedly connected to the end of the electroplating frame. The slider is slidably connected to the slide rail, and the length direction of the slide rail is parallel to the length direction of the electroplating frame.

[0010] To achieve the above technical solution, each end of the electroplating rack is equipped with a slider that cooperates with the slide rail. These sliders can slide smoothly along the slide rail, forming a linear guiding mechanism. This ensures that when the electroplating rack drives the hanging bracket in reciprocating motion, the trajectory is straight and smooth, effectively avoiding lateral swaying or deviation.

[0011] In a preferred embodiment of this utility model, a baffle is fixedly connected to the fixing frame, and the slide rail and slider are located inside the baffle.

[0012] The above technical solution enhances the protection of the slide rail and slider, preventing electroplating solution from dripping onto them.

[0013] As a preferred embodiment of this utility model, a holding rod is fixedly connected to the electroplating rack, and the holding rod is located on the side of the electroplating rack facing away from the support plate.

[0014] By implementing the above technical solution, when the power gear is neither engaged with the first rack nor the second rack, the operator can hold the lever to push the electroplating rack to move back and forth, thus realizing the reciprocating movement of the electroplating rack both manually and automatically, improving practicality.

[0015] As a preferred embodiment of this utility model, a partition is provided on the support plate, the partition is located between two adjacent hangers, and the side wall of the partition is used to abut against the side wall of the hanger.

[0016] To achieve the above technical solution, by setting up partitions, during the horizontal reciprocating motion of the electroplating rack, the abutting action of these partitions located between the racks against the side walls of the racks effectively suppresses the possible collisions between the racks, thereby preventing collisions between electroplated products.

[0017] In a preferred embodiment of this utility model, a receiving groove is provided in the middle of the partition, and the support plate passes through the receiving groove.

[0018] The above technical solution enables the partitions to slide on the support plate, allowing the distance between adjacent partitions to be adjusted arbitrarily to accommodate racks of different widths and improve practicality.

[0019] As a preferred embodiment of this utility model, a positioning plate is fixedly connected to the upper end of the partition, a sliding groove is provided along the length of the electroplating rack, the positioning plate is placed in the sliding groove, the positioning plate is in contact with the side wall of the sliding groove, and the bottom wall of the receiving groove is in contact with the bottom wall of the support plate.

[0020] To achieve the above technical solution, during the electroplating process, if the support plate deforms downwards due to excessive load or other reasons, the inner wall of the receiving tank presses against the lower surface of the support plate. This abutting action provides a support point for the downwardly bending support plate, effectively limiting the extent to which the support plate continues to bend severely downwards. This prevents catastrophic severe deformation or fracture of the support plate when it experiences structural weakening or overload, thereby avoiding potential equipment damage or production accidents and significantly improving the reliability and safety of the equipment operation.

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0029] A horizontally swinging electroplating apparatus includes a fixed frame 1 and an electroplating rack 2. The fixed frame 1 is horizontally positioned, with the electroplating rack 2 spanning across it. A slide rail 3 is fixedly connected to the fixed frame 1, and a slider 4 is fixedly connected to the end of the electroplating rack 2, slidably connected to the slide rail 3. The length direction of the slide rail 3 is parallel to the length direction of the electroplating rack 2, allowing the electroplating rack 2 to reciprocate along its length. The electroplating tank is located below the electroplating rack 2.

[0030] A support plate 5 for hanging racks 18 is fixedly connected to the electroplating rack 2. The length direction of the support plate 5 is parallel to the length direction of the electroplating rack 2, and multiple racks 18 are arranged along the length direction of the support plate 5.

[0031] A power motor 6 is fixedly connected to the fixed frame 1, and a power wheel 9 is fixedly connected to the power shaft of the power motor 6. The power wheel 9 is coaxially arranged with the power shaft. A first rack 7 and a second rack 8 are fixedly connected to the end of the electroplating rack 2. The length directions of the first rack 7 and the second rack 8 are both parallel to the length direction of the electroplating rack 2.

[0032] A drive gear 10 is fixedly connected to the outer wall of the drive wheel 9. Multiple drive gears 10 are not evenly distributed along the axis of the drive wheel 9. After the drive wheel 9 rotates, the drive gear 10 meshes with the first rack 7, causing the first rack 7 to move the electroplating rack 2 along the slide rail 3 in the forward direction. After the drive gear 10 separates from the first rack 7, the electroplating rack 2 stops moving. Subsequently, the drive gear 10 meshes with the second rack 8, and similarly, the electroplating rack 2 moves in the reverse direction. This allows the electroplating rack 2 to reciprocate along its own length.

[0033] The electroplating rack 2 includes a fixing plate 11, and a holding rod 12 is fixedly connected to the side wall of the fixing plate 11. The holding rod 12 is located on the side of the fixing plate 11 opposite to the support plate 5. Each fixing plate 11 has two holding rods 12.

[0034] The electroplating rack 2 has a groove 13 along its length, and the groove 13 has a T-shaped cross-section. A positioning plate 14 is slidably connected within the groove 13, and the lower surface of the positioning plate 14 is in contact with the inner wall of the groove 13. A partition 15 is vertically fixed to the positioning plate 14, passing through the groove 13 and extending towards the support plate 5. The partition 15 is located between two adjacent hangers 18. The sidewall of the partition 15 is designed to abut against the sidewall of the hanger 18 to prevent collision between the two hangers 18.

[0035] A receiving groove 16 is provided in the middle of the partition 15, and the support plate 5 passes through the receiving groove 16. The lower surface of the support plate 5 is in contact with the bottom wall of the receiving groove 16.

[0036] A baffle 17 is fixedly connected to the fixed frame 1, and the slide rail 3 and the slider 4 are located inside the baffle 17.

[0037] The power motor 6 drives the coaxially connected power wheel 9 to rotate via a power shaft. Multiple power teeth 10 are fixed to the outer wall of the power wheel 9, and these teeth 10 are not evenly distributed along the axis of the power wheel 9. When the power wheel 9 rotates, the power teeth 10 on its outer wall first mesh with the first rack 7 fixedly connected to the end of the electroplating rack 2. The rotation of the power teeth 10 pushes the first rack 7, and since the first rack 7 is fixed to the electroplating rack 2, this meshing causes the entire electroplating rack 2 to move horizontally in the positive direction along the slide rail 3 on the fixed frame 1.

[0038] After the drive gear 10 disengages from the first rack 7, the electroplating rack 2 stops moving. Then, the drive wheel 9 continues to rotate, and the drive gear 10 engages with the second rack 8. The rotation of the drive gear 10 pushes the second rack 8, causing the electroplating rack 2 to move horizontally in the opposite direction along the slide rail 3. This reverse movement of the electroplating rack 2 continues until the drive gear 10 disengages from the second rack 8.

[0039] The drive wheel 9 rotates continuously, driving the electroplating rack 2 to move back and forth continuously along its own length direction, moving in the forward, stop, reverse and stop directions.

[0040] The partition 15 is located between adjacent hangers 18 and abuts against the side wall of the hanger 18 when the electroplating rack 2 moves, providing lateral support and limiting. The receiving groove 16 in the middle of the partition 15 allows the support plate 5 to pass through, and when the support plate 5 bends downward, the bottom wall of the receiving groove 16 abuts against the lower surface of the support plate 5, providing additional support.

[0041] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
