Description

Insert group type electroplating workpiece fixture

The invention relates to a positioning frame body for electroplating; in particular, it refers to an innovative interspersing and inserting group type electroplating workpiece fixture structure revealer.

The electroplating workpiece fixture referred to in the present invention is a special positioning frame body for mounting and disposing the electroplating workpiece in a set position and angle state, in order to achieve a better electroplating effect.

Conventional fixtures for electroplating workpieces, the common type of frame body usually adopts the integrated bending method of metal plates (Note: because the required quantity is not large, usually the industry will abandon the establishment of stamping dies and use manual manual bending methods) or split type The required horizontal frame part and the vertical frame part are formed by welding together, and then a clamping and positioning member is arranged at the end of the vertical frame part for clamping on the preset foot position of the electroplating workpiece. Depending on different factors such as the size, three-dimensional shape, and contour characteristics of the electroplated workpiece, the number and position of the aforementioned feet and the configuration of the clamping and positioning components are relatively different.

However, the conventional electroplating workpiece fixture is criticized in the practical application. A common point is that the accuracy error of the bending part of the metal plate is too large, because the end of the stand is provided with a clamping point for clamping the positioning member The position may be due to phenomena such as qualitative rebound of the part after bending or inaccurate welding alignment, etc., and there is an excessive deviation value. This error value may not be a big problem for a single point, but when a single point When the number of multiple pins to be clamped by the electroplating workpiece is larger, the cumulative result of the multi-point error value will cause obstacles in the process of installing the electroplated workpiece on the electroplating workpiece fixture, which will cause the electroplating work schedule to delay and the processing cost. The problem of relative improvement is also a major problem faced by electroplating workpieces with two-pin and multi-pin types in the electroplating process.

Continuing from the previous paragraph, the problem of deformation of electroplated workpieces may also arise. Because some electroplated workpieces are made of plastic and have too many slender and weak shapes, the overall shape is not rigid. Once such electroplated workpieces face the deviation of the aforementioned clamping and positioning member When the error value is too large, in order to actually install the electroplating workpiece on the electroplating workpiece fixture, the personnel must force the offset stand to force it to be clamped in the correct position. However, in this case, the stand The elastic force accumulated when it is pulled will produce a rebound force after clamping to pull the electroplated workpiece to produce deformation (such as twisting, arc warping, etc.), and this deformation will undergo various chemical immersion processes in the electroplating workpiece. Afterwards, it may be finalized and difficult to restore, resulting in poor electroplating quality, defective electroplated workpieces (such as inaccurate fit when installed on the product) and other problems. This is the current conventional electroplated workpiece fixture structure, which is common The main reason for not meeting the quality requirements of high-precision electroplating workpieces.

In terms of further derivation of the problem, the aforementioned conventional electroplating workpiece fixtures cannot solve the problems of workpiece distortion and poor quality and positioning accuracy. Then, when the industry wants to further introduce robotic arms to the product electroplating assembly line to achieve In high-efficiency automated assembly, there are obviously bottlenecks and obstacles that are difficult to achieve, which leads to serious problems of difficulty in industrial upgrading.
