Description

Technical Field

[0001] This utility model relates to the field of terminal processing, and in particular to a workpiece positioning and correction device for terminal electroplating equipment. Background Technology

[0002] Workpiece positioning calibration in terminal electroplating equipment refers to the process of precisely adjusting and correcting the installation position, angle, and posture of electroplating workpieces (such as terminals) in the equipment through mechanical structures or sensing devices. This ensures that the workpieces can be accurately aligned with the electrodes and electroplating solution during the electroplating process, achieving uniform and high-quality electroplating results. At the same time, it avoids poor electroplating, workpiece damage, or equipment failure caused by positional deviations, thereby improving production efficiency and product consistency.

[0003] In current terminal electroplating processes, the immersion depth is mostly adjusted manually. However, this manual adjustment lacks a precise control mechanism, resulting in inconsistent and unstable immersion depths. Different batches, and even the same batch, may exhibit significant variations in immersion depth due to operator experience, visual judgment errors, or the arbitrariness of manual operation. Over-immersion can cause non-plating areas to be coated, leading to product scrap or requiring additional removal processes and increased costs. Conversely, under-immersion results in insufficient plating thickness or incomplete plating in the areas to be plated, severely impacting the terminal's electrical performance, corrosion resistance, and appearance. Furthermore, unstable immersion depth leads to uneven plating thickness distribution, creating noticeable demarcation lines or color differences on the terminal surface, reducing product aesthetics and market competitiveness. It also increases quality control workload and defect rates. Additionally, the lack of angle control devices for direct terminal placement during electroplating makes it difficult to precisely adjust and fix the relative angle between the terminal and the plating solution surface or electrodes, easily leading to terminal tilting, twisting, or unstable suspension. Angular deviations can lead to significant differences in the distance between different parts of the terminal and the electrode. According to the principles of electroplating, areas closer to the electrode will receive a thicker plating layer, while areas farther away will have a thinner plating layer, resulting in a severely uneven plating thickness distribution. This is especially problematic for terminals with complex shapes and multiple plating surfaces, where improper angles can cause some critical surfaces to fail to be effectively plated or result in problems such as trapped air bubbles and poor liquid flow. Furthermore, unstable terminal posture can cause displacement or rotation during the electroplating process due to liquid disturbance and rising air bubbles, further exacerbating the instability of electroplating quality, increasing rework rates, and wasting materials. In addition, repeatedly adjusting the position and angle manually not only consumes a significant amount of time and labor costs, reducing production efficiency, but also makes it difficult to achieve standardized operations and automated production, thus limiting the development needs of capacity expansion and intelligent manufacturing.

[0004] Therefore, a workpiece positioning and correction device for terminal electroplating equipment is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a workpiece positioning and correction device for terminal electroplating equipment, which has the advantages of precise height control, precise angle control, and ensuring stability and consistency during electroplating.

[0009] The height correction component includes a height adjustment seat disposed on the lower end face of the support base. The side end face of the height adjustment seat has a rectangular slot and a lead screw nut is embedded therein. A support seat is sleeved on the outside of the lead screw nut. A rectangular slot is disposed on the upper end face of the support seat.

[0010] The angle correction assembly includes a base plate mounted on the lower end face of the support, and a rotary motor is mounted on the lower end face of the base plate.

[0011] Furthermore, the height correction component also includes two bearing seats disposed within the height adjustment seat, each bearing seat containing a bearing component which is respectively disposed at the upper and lower ends of the height adjustment seat.

[0012] Furthermore, a threaded screw is rotatably provided between the two bearing seats, the threaded screw passing through and meshing with a screw nut.

This ensures uniform angle of the terminals during electroplating and avoids uneven electroplating caused by tilting. Attached Figure Description

[0042] Sixth embodiment;

[0043] Reference Figure 1-2 As shown, a terminal limiting fixture 6 is installed at the bottom of the support rod 5.

[0044] In this embodiment, a terminal limiting fixture 6 is installed at the bottom of the support rod 5. The limiting fixture 6 is used to fix the position of the terminal, prevent the terminal from shifting during the electroplating process, and ensure the accuracy and stability of the positioning correction.

[0045] Furthermore, the terminal limiting fixture 6 is an existing mature fixture, which is used to limit the terminal workpiece.

[0046] Specific implementation process

[0047] Step 1: First, install the terminal limiting fixture 6 at the bottom of the support rod 5. Adjust the clamping structure of the terminal limiting fixture 6 according to the specifications and shape of the terminal to be electroplated to ensure that the terminal can be stably and reliably fixed on the fixture. Assemble and connect the support rod 5 with the clamped terminal to the connecting plate 34 on the angle correction component 3 through the mounting base 4, so that the entire workpiece support system is installed at the output end of the rotary motor 32 through the rotating table 33, and is connected and fixed to the lower end face of the support seat 25 of the height correction component 2 through the base plate 31. At this time, the entire device is in the initial state, and the terminal is suspended below the bracket 1 through the support rod 5, waiting for precise height and angle correction and adjustment.

[0048] Step 2: Start the reversible motor 26. Its output end passes through the height adjustment seat 21 and drives the top of the threaded screw 23 to rotate. The threaded screw 23 rotates stably under the support of two bearing seats 22 and the bearing components installed inside the height adjustment seat 21. Through the threaded engagement with the screw nut 24, the rotational motion is converted into linear motion. When the reversible motor 26 rotates forward, the threaded screw 23 drives the screw nut 24 to move upward. The screw nut 24 is embedded in the rectangular slot on the side end face of the height adjustment seat 21 and is constrained, so it can only perform linear motion in the vertical direction and will not rotate. This causes the externally sleeved support seat 25 and the entire angle correction component 3, mounting seat 4 and support rod 5 in the rectangular slot on its upper end face to rise as a whole. Conversely, when the reversible motor 26 rotates in reverse, the entire system lowers downward. By controlling the rotation direction, speed and rotation angle of the reversible motor 26, the immersion depth of the terminals in the electroplating solution can be precisely controlled, achieving accurate correction and stable control of the height position, and ensuring the consistency of the immersion depth of terminals in different batches.

[0049] Step 3: After height adjustment, start the rotary motor 32 installed on the lower end of the base plate 31. Its output drives the rotating platform 33 to rotate, and the connecting plate 34 installed on the rotating platform 33 rotates synchronously, causing the entire mounting base 4, support rod 5, terminal limiting fixture 6, and the clamped terminals to adjust their angles around the vertical axis. By controlling the rotation angle of the rotary motor 32, the relative angle and posture between the terminals and the electroplating solution surface and electrodes can be precisely adjusted, ensuring that each surface of the terminal to be electroplated maintains the optimal relative position with the electrodes, ensuring uniform electric field distribution, smooth flow of the electroplating solution, and timely removal of air bubbles. After angle correction, the entire system is fixed in the set position by the bracket 1. The terminals are immersed in the electroplating solution at the corrected precise height and angle for electroplating. The entire process achieves dual precise control of height and angle, significantly improving the uniformity of electroplating layer thickness, product quality consistency, and production automation level, effectively solving the problems of inaccuracy and instability of manual adjustment.
