Description

Electroplating rack for improving uniformity of electroplated layer

Technical Field

The utility model discloses electroplating device technical field, concretely relates to promote electroplating layer homogeneity's electroplating stores pylon.

Background

Electroplating is a process of plating a thin layer of other metals or alloys on the surface of some metals by using the principle of electrolysis, and is a process of attaching a layer of metal film on the surface of a metal or other material product by using the action of electrolysis so as to play roles of preventing metal oxidation, improving wear resistance, conductivity, light reflection, corrosion resistance, enhancing appearance and the like. During electroplating, plating metal or other insoluble materials are used as an anode, a workpiece to be plated is used as a cathode, and cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer. The electroplating rack is a necessary device in electroplating industry, it mainly includes a main frame body, main hook set on the main frame body and placing rack for placing plating piece, when the plating piece is placed on the placing rack, it is inserted into plating bath, and the electroplating rack is used as cathode for electroplating, after the current is passed between cathode and anode, the power line distribution diagram shown in figure 1 can be appeared, i.e. the distribution of power line in the plating bath possesses the characteristics of two-end concentration and less middle. Thereby causing the coating of the tip of the plated object to be thicker and uneven, and affecting the overall electroplating effect.

SUMMERY OF THE UTILITY MODEL

To foretell not enough, the utility model provides a promote electroplating layer homogeneity's electroplating stores pylon, the purpose has both ends to concentrate, the centre is few partially in order to solve among the prior art distribution of power line in the plating bath to arouse that plated object pointed end cladding material is thicker, make cladding material all uneven, influence the technical problem of holistic electroplating effect.

The utility model provides an electroplating rack for improving uniformity of electroplated layer, the concrete technical scheme is as follows:

an electroplating rack for improving the uniformity of an electroplated layer comprises two hanging rods which are arranged in parallel, the upper end parts of the hanging rods are provided with hooks, the hanging rods are detachably connected through two cross rods, the cross rods are mutually parallel and arranged at intervals, a plurality of supporting rods are movably arranged on the cross rods, conductive contacts are arranged on the supporting rods,

still block the chase including the electric current, the electric current blocks the chase and is the rectangle structure, the electric current blocks the chase cover and establishes on the bracing piece, and with bracing piece tight fit, and with the conductive contact sets up, the thickness that the electric current blockked the chase is greater than the thickness of waiting to plate the part.

In some embodiments, the cross bar is provided with a sliding groove, and the support bar is arranged in the sliding way.

In some embodiments, the hanging rod is uniformly provided with a plurality of grooves, and the cross rod is detachably inserted into the grooves.

The utility model discloses following beneficial effect has: the utility model discloses a setting that the electric current blockked the chase has played the effect of supplementary negative pole, adds the negative pole near most advanced position in addition for consume the partial current, eliminate and plated the phenomenon such as uneven and scorching of electroplating that the most advanced position appears because the power line is too concentrated on the finished piece. In addition, the movable support rod that sets up on detachable horizontal pole and the horizontal pole can the adjusting distance to adapt to different height, wide electroplating piece, thereby realize improving the homogeneity of electroplated layer, promote the whole quality of product, in addition, simple structure, it is extensive to use.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings 1-4 in conjunction with the following embodiments.

promote electroplating layer homogeneity's electroplating rack, including two peg 1 of parallel arrangement, the upper end of peg 1 is equipped with couple 12, is convenient for hang and carries out the rack plating on the stores pylon. The hanging rods 1 are detachably connected through two cross rods 2, and the cross rods 2 are parallel to each other and arranged at intervals. The hanging rod 1 and the cross rod 2 form a rectangular frame, the cross rod 2 can be detached, and the cross rods 2 installed at different positions are matched, so that the hanging rod can adapt to plated objects with different heights. The movable multiple bracing pieces 21 that are provided with on the horizontal pole 2, be provided with electrically conductive contact on the bracing piece 21, bracing piece 21 is used for the card to establish the quilt and plates the thing, and the bracing piece 21 that the activity was adjusted can adapt to the quilt and plates the thing of different width, still includes that the electric current blocks chase 3, and the electric current blocks the chase and is the rectangle structure, and the electric current blocks chase 3 cover and establishes on bracing piece 21, and with bracing piece 21 tight fit, the thickness that the electric current blockked chase 3 is greater than the thickness of waiting to plate the part. The current blocking iron frame 3 is matched with the conductive contact to play a role of an auxiliary cathode, and a cathode is additionally arranged near the tip part to consume partial current so as to eliminate the phenomena of uneven electroplating, scorching and the like caused by over concentration of a power line at the tip part of a plated workpiece.

In some embodiments, the cross bar 2 is provided with a sliding groove 22, and the support bar 21 is slidably disposed. Thus, the support rods 21 can be arbitrarily slid to adjust the distance between the support rods 21 on the same crossbar 2.

In some embodiments, the hanging rod 1 is uniformly provided with a plurality of grooves 11, and the cross rod 2 is detachably inserted into the grooves 11. The cross bar 2 is inserted into the grooves 11 at corresponding positions according to the plated objects at different heights.
