Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, and in particular to a lamp base strip electroplating equipment and a preparation production line. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics. During electroplating, the plating metal or other insoluble material serves as the anode, and the workpiece to be plated serves as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer. In order to eliminate the interference of other cations and make the plating uniform and firm, a solution containing the plating metal cations is required as the electroplating solution to keep the concentration of the plating metal cations unchanged.

[0003] LED lamp basebands are increasingly used in the decorative lighting market due to their long service life, energy saving and environmental protection. Currently, LED lamp basebands are usually composed of lamp beads and flexible printed circuits (FPC). However, during the production process of its core component, flexible printed circuits (FPC), especially during the electroplating process, complex wastewater containing heavy metals and organic matter will be generated, which is difficult to treat and pollutes the environment. Among them, when LED lamp basebands are electroplated using traditional electroplating equipment, it is often difficult to ensure the uniformity of the electroplating layer, resulting in unstable product quality.

[0041] For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] Regarding the drawings of the present application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0043] Embodiment 1:

[0044] like Figure 1 FIG. 1 is an example of a light baseband, wherein the light baseband includes:

[0045] The base portion 1 is insulating; it should be understood that the base portion 1 can be made of insulating material, such as polyimide or polyester material.

[0046] Secondly, an insulating layer may also be added to the surface of the base portion 1, for example, an oxide film or an insulating coating or an insulating sticker may be provided on the metal substrate.

[0047] The base portion 1 is in the form of a sheet or a rolled strip.

[0048] The conductive part 2 is disposed on the base part 1 . The conductive part 2 can be made of materials such as copper foil and can be directly stamped on the base part 1 .

[0049] And a plating part, wherein the plating part is plated on at least a part of the conductive part 2, for example, nickel is plated on a copper foil, and generally different lamp bases have different nickel plating requirements.

[0050] Secondly, if the conductive part 2 does not need to be plated with the electroplating part in its entirety during electroplating, a shielding body can be used to shield the area except the electroplating part. In this embodiment, the shielding body is insulating.

[0051] Based on the above light baseband, such as Figures 2 to 5 As shown, the present application provides a lamp base strip electroplating device for electroplating the lamp base strip, comprising:

[0052] The electroplating chamber 3 contains a plating solution. The plating solution and the amount of the plating solution are selected according to actual needs.

[0053] The electroplating assembly 4 includes an electroplating electrode 41, and the electroplating electrode 41 includes a fixing plate 411 and a plurality of conductive bristles 412 disposed on the fixing plate 411, and the conductive bristles 412 are made of conductive fibers; preferably, the conductive bristles 412 are made of steel fiber materials. Secondly, it should be understood that the electroplating assembly 4 also includes a power supply circuit, and the electroplating electrode 41 needs to be powered during electroplating.

[0054] The special electroplating electrode 41 uses conductive fibers to make conductive bristles 412, which can accurately control the position and range of electroplating, improve the accuracy and efficiency of electroplating, and at the same time has a certain flexibility and elasticity, can adapt to lamp base strips of different shapes and sizes, and improve the applicability and flexibility of the equipment.

[0055] and a conveying assembly 5, the conveying assembly 5 is used to continuously convey the lamp base belt through the electroplating assembly 4; specifically, the conveying assembly 5 includes:

[0056] A plurality of conveying rollers 51 are arranged at intervals along the length direction of the electroplating chamber 3; the conveying rollers 51 are arranged to rotate relative to the electroplating chamber 3. It should be understood that a sealing arrangement is required here to avoid leakage of the electroplating solution.

[0057] In this embodiment, each conveying roller 51 is arranged in an inverted trapezoidal shape, so that the lamp base strip can be fully immersed in the electroplating liquid during conveyance.

[0058] The traction roller is used to pull the electroplated substrate and transport it on the conveying roller 51. It should be understood that the conveying component 5 also includes a drive and a corresponding transmission mechanism.

[0059] Among them, a plurality of mounting parts 6 are arranged above the conveying roller 51. In the present embodiment, the mounting parts 6 can be connected by embedding grooves, bolts, snap connections, etc., preferably a detachable mounting structure is used to facilitate the replacement, repair and maintenance of the electroplating electrode 41.

[0060] Secondly, the plurality of mounting portions 6 are spaced apart along the length direction of the electroplating chamber 3 , and the plurality of mounting portions 6 are all provided with the electroplating electrodes 41 , which greatly improves the electroplating efficiency and the electroplating quality.

[0061] Among them, the lamp base strip and at least part of the electroplating component 4 are immersed in the electroplating liquid, and usually the conductive bristles 412 need to be immersed in the electroplating liquid. When the conveying component 5 conveys the lamp base strip, the conductive bristles 412 contact the part of the lamp base strip that needs to be electroplated and are energized, so that the contacting part can be electroplated.

[0062] In addition, when the traditional LED lamp baseband is electroplated, the areas that do not need electroplating are first treated with anti-plating. Generally, chemical coating is used to protect the non-plated areas, and then full coverage electroplating is used. After plating, the chemical coating is removed. This results in low efficiency, increased costs and environmental impact.

[0063] When the electroplating equipment is used to plate the electroplated part, the conductive bristles 412 will plate the conductive part 2 to be plated when in contact with the lamp base band, while not plating the base part 1, thereby achieving local electroplating or island electroplating or point plating, which can significantly reduce production costs and improve production efficiency. At the same time, compared with traditional full-coverage electroplating, it reduces the use of chemical substances and the generation of waste liquid, which is in line with the development trend of green manufacturing.
