In this embodiment, electroplating The short sides 111 (see FIG. 2) of the jig 11 of the jig 1 are positioned on the corresponding side uprights 312, and such a tight arrangement has high economic efficiency.

Referring to FIG. 11, the following description uses the electroplating jig 1 to position the workpiece 2 to be electroplated, and then positions the electroplating jig 1 on the plating rack 3 for electroplating. Referring to FIG. 1 and FIG. 2, first, the workpiece 2 to be plated is placed on the plate body 11 of the electroplating jig 1, and according to the mutual arrangement condition of the electroplated workpiece 2 and the electroplating jig 1, an appropriate stopper 121 is selected and positioned. The plate body 11 abuts against the periphery of the workpiece 2 to be plated. The stopper 121 provides a function of blocking the slip of the workpiece 2 to be plated and providing positioning.

Referring to FIG. 1 , FIG. 2 and FIG. 7 , the locking screw 123 of the locking member 122 passes through the stopper 121 and the selected first hole 112 , the first long hole 113 , the second long hole 114 , and the third long hole . 115, one of the L-shaped hole 116 and the T-shaped hole 117, and locked with a nut 124 that abuts the plate body 11, thereby positioning the workpiece 2 to be plated on the plating fixture 1. The stopper 121 and the nut 124 respectively abut against the opposite side of the plate body 11.

The stopper 121 can match the position of one of the first hole 112, the first long hole 113, the second long hole 114, the third long hole 115, the L-shaped hole 116 and the T-shaped hole 117, and select an appropriate size and Shape to position the workpiece 2 to be plated. In the electroplating process, the plating solution is liable to remain in the contact area between the workpiece 2 to be plated and the stopper 121, thereby increasing the trouble of the subsequent treatment of the residual plating solution. Preferably, the concentric circular block 121 of FIG. 3 and the eccentric circular stop 121 of FIG. 4 are preferred objects for use because of the small contact area with the periphery of the workpiece 2 to be plated.

Referring to Figures 1, 8, and 10, next, the plating rack 3 will be The positioning hooks 321 of the positioning unit 32 respectively extend through the positioning holes 131 of the plate body 11 of the plating fixture 1 to position the plating fixture 1 on the plating rack 3.

Then, the electroplating needle 33 is moved to the area to be electroplated of the workpiece 2 to be electroplated by a tool, and the guiding portion 331 of the unnecessary electroplating needle 33 is insulated and covered to avoid the formation of a plating layer during the electroplating process, thereby affecting the plating. The life of the electroplated needle 33 is maintained, and the lead portion 331 of the electroplated needle 33 is prevented from scratching the workpiece 2 to be plated. Referring to FIG. 1 and FIG. 11, each electroplating fixture 1 is positioned to at least one workpiece 2 to be electroplated, and the electroplating fixture 1 is positioned on the electroplating rack 3, and after being set, the electroplating operation is performed by placing the electroplating device. In other words, if the workpiece 2 to be electroplated is small in size, a plurality of workpieces 2 to be electroplated can be positioned on the same electroplating jig 1.

Referring to FIG. 1 and FIG. 2, it should be noted that the plate body 11 of the electroplating jig 1 is designed to increase the fluidity of the plating solution and to arrange different numbers and positions without affecting the strength of the plate body 11. The first long hole 113, the second long hole 114, the third long hole 115, the L-shaped hole 116 and the T-shaped hole 117 are used to make the plating film of the workpiece 2 to be plated more uniform.

Specifically, the fluidity of the plating solution is poor due to the central portion of the plate body 11, and the fluidity of the plating solution can be improved by the first long hole 113 being a longitudinally long hole. In this embodiment, the longitudinal first long hole 113 is parallel to the edge line of the short side 111 of the plate body 11, and is mainly designed with the third long hole 115 and the matching block 121, so that most of the workpiece to be plated 2 Obtaining a secure positioning, of course, if a workpiece 2 to be electroplated of a particular size is selected, the first long hole 113, the second long hole 114, the L-shaped hole 116 and the T-shaped hole 117 and the mating stop 121 may be selected to enable the present invention Electroplating fixture 1 becomes applicable to a variety of A general-purpose electroplating jig 1 for the workpiece 2 to be electroplated.

Finally, since the plating needle 33 of the plating rack 3 is disposed at the center of the plating zone 314, the plating needle 33 can be moved to a different plating position of the workpiece 2 to be plated, such as to a side of the workpiece 2 to be plated. The position to be plated is such that the plating rack 3 of the present invention becomes a general-purpose plating rack 3 that can be placed in conjunction with the workpiece 2 to be plated. In addition, when the guiding portion 331 of the electroplating needle 33 is worn out for a long period of time, the guiding portion 331 can be returned to the usable state by grinding, until the electroplating needle 33 is shortened by multiple times and cannot contact the workpiece to be plated 2 Only when a new plating rack 3 is required. Through the general-purpose electroplating jig 1 and the general-purpose electroplating rack 3, it is not necessary to design a specific electroplating jig 1 and a plating rack 3 for different sizes of the workpiece 2 to be plated, which can greatly reduce the cost of the electroplating process and shorten the production. The waiting time of the specific plating jig 1 and the plating rack 3 improves the plating efficiency.

If only the workpiece 2 to be electroplated has to be electroplated, only the workpiece 2 to be electroplated has to be positioned on the electroplating fixture 1, and the electroplating fixture 1 is detachably coupled to one of the electroplating regions 314 of the conductive frame 31. The workpiece 2 to be plated is thereby detachably contacted with the guiding portion 331 of one of the plating pins 33.

Referring to FIG. 2 and FIG. 12, if the size of the workpiece 2 to be plated is slightly larger, when the workpiece 2 to be plated is placed on the plate 11 of the plating fixture 1, the positioning relationship between the positioning hook 321 and the positioning hole 131 has been interfered. At this time, by the elasticity of the positioning hook 321 , the position of the fine adjustment positioning hook 321 is changed from the direction of the workpiece 2 to be plated to the opposite direction to the edge of the short side 111 of the plate body 11 , and the plate body 11 can still be positioned on the conductive frame. On the plating zone 314 of the body 31.

It is worth noting that the electroplating fixture 1 shown in FIG. 1 has The adjustable limiting unit 12 can be positioned on the periphery of the workpiece 2 to be plated by adjusting each of the limiting units 12, so that the workpieces 2 to be plated of different sizes can share the same size of the plating fixture 1 and the electroplating fixture 1 can be used. Flexibility.

Referring to Figures 13 and 14, a second preferred embodiment of the combination of the electroplating jig and the electroplating pylon of the present invention is substantially the same as the first preferred embodiment, the main difference being the electroplating jig 1. The structure of the electroplating jig 1 of the present embodiment is to provide a general-purpose electroplating jig 1 for positioning different sizes of the workpiece 2 to be plated.

The plate body 11 of the electroplating jig 1 includes only a plurality of first holes 112 spaced apart and penetrating. In this embodiment, the first holes 112 are all circular holes, wherein the arrangement patterns of the first holes 112 are arranged in a longitudinal direction, and each of the four first holes 112 is arranged in a row to form a first group, each of which is five A hole 112 is arranged in a row and combined into a second group. The four first holes 112 of each first group and the five first holes 112 of each second group are arranged at intervals of the arrangement direction of the parallel short sides 111. And the four first holes 112 of the first group and the five first holes 112 of the second group are staggered with each other.
