[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a cathode conductive free contact copper carbon brush group for a continuous electroplating line, comprising a connecting plate 1, the front and rear bottom walls of the connecting plate 1 are fixedly connected with a cathode 2, the middle parts of the front and rear sides of the connecting plate 1 are fixedly connected with two connecting frames 3, the adjacent sides of multiple connecting frames 3 are fixedly connected with a protective plate 4, the bottom walls of the two protective plates 4 are fixedly connected with a fixing plate 5, the bottom walls of the two fixing plates 5 are equidistantly threaded with multiple bolts 6, the outer walls of the multiple bolts 6 are threaded with a copper shell 7, the inner walls of the multiple copper shells 7 are fixedly connected with a spring 8 on the side away from the inner walls, the adjacent sides of the multiple springs 8 are fixedly connected with a copper carbon brush plate 9, the front and rear sides of the multiple copper carbon brush plates 9 are fixedly connected with a fixing bolt 10, the front and rear sides of the multiple copper shells 7 are provided with a slide groove 13, the middle parts of the multiple fixing bolts 10 are respectively slidably connected with the corresponding slide grooves 13, and the inner walls of the multiple copper shells 7 are provided with a limit assembly on the side away from the inner walls; the adjacent sides of the multiple copper carbon brush plates 9 are provided with an inclined surface;

[0030] Specifically, the copper-carbon brush plate 9 is in close contact with the surface of the electroplated part to form a stable conductive connection. This step is to ensure that the current can be smoothly transmitted from the power supply to the surface of the electroplated part, triggering a chemical reaction in the electroplating solution, thereby achieving the smooth completion of the electroplating process. The movement and free contact design of the copper-carbon brush plate 9 ensure that the current is evenly distributed on the surface of the electroplated part. This design concept stems from the action of the spring 8, which enables the copper-carbon brush plate 9 to move freely inside the copper shell 7. In this way, regardless of the shape and surface condition of the electroplated part, the copper-carbon brush plate 9 can adjust the contact position and force as needed to ensure uniform transmission of current. This free contact design effectively solves the problem of uneven coating thickness caused by uneven current density. Because the current transmission requirements are different on electroplated parts of different shapes and sizes. The copper-carbon brush plate 9 can slide inside the slide groove 13 through the spring 8 and the fixing bolt 10 according to the actual situation of the electroplated part, and independently adjust the contact position and force to achieve uniform current transmission.

[0031] Reference Figure 2 and Figure 3 The limit assembly includes a plurality of positioning columns 11, the outer walls of the plurality of positioning columns 11 are fixedly connected to the inner walls of the plurality of copper shells 7 on the side away from each other, the plurality of copper carbon brush plates 9 are provided with holes 12 on the side away from each other, and the adjacent sides of the plurality of positioning columns 11 are respectively slidably connected with the corresponding holes 12; the sides away from each other of the plurality of fixing bolts 10 are provided with hexagonal grooves 17; the internal dimensions of the plurality of holes 12 match the dimensions of the front outer walls of the plurality of positioning columns 11;

[0032] Specifically, the adjacent sides of the multiple positioning columns 11 are respectively slidably connected with the corresponding hole grooves 12, so that the copper-carbon brush plate 9 will not be offset and fall when sliding. The multiple hexagonal grooves 17 make it easy to use tools to adjust the fixing bolt 10. The internal dimensions of the multiple hole grooves 12 are matched with the dimensions of the front outer walls of the multiple positioning columns 11, so that the copper-carbon brush plate 9 can slide more smoothly.

[0033] Reference Figure 1 , a plurality of power-on clips 14 are fixedly installed on the top wall of the connecting plate 1 at equal intervals; the tops of the plurality of power-on clips 14 are all symmetrically designed; a plurality of snap-fit ​​frames 15 are fixedly connected to the front side of the connecting plate 1 at equal intervals, and the front right ends of the plurality of snap-fit ​​frames 15 are all rotatably connected to locking clips 16, and the bottom right sides of the plurality of locking clips 16 are respectively snap-fitted with the front left ends of the corresponding snap-fit ​​frames 15;

[0034] Specifically, multiple power-on clamps 14 facilitate the electrical connection between the cathode 2 and the power supply. The tops of the multiple power-on clamps 14 are symmetrically designed to make the clamping more stable. The bottom right sides of the multiple locking clamps 16 are respectively engaged with the front left ends of the corresponding snap-fit ​​frames 15, which facilitates improving the stability of the connecting plate 1.

[0035] Working principle: In PCB\FPC electroplating, PCB\FPC products are electroplated by moving the carrier. When they reach the electroplating chemical tank, they need to be electroplated on the surface through the physical action of the negative (negative) and positive (positive) electrodes of the current. In the actual use of the continuous electroplating line, the cathode current conduction method, the rectifier power supply is connected to the cathode conductive carbon brush through the fire cow line, and the PCB\FPC product carrier flying target is stably contacted during the moving operation to conduct the cathode current, thereby maximizing the electroplating efficiency of the PCB\FPC products and optimizing the uniformity, quality and yield.

[0036] This new application invention has two most prominent features in the current electroplating line industry:

[0037] (1) The above description is one of the necessary conditions for PCB\FPC product electroplating; cathode current. Due to its ingenious mechanical structure design, the PCB\FPC product transmission carrier is guaranteed to fly; the stable contact with the conductive carbon brush during the mobile operation ensures the stability and reliability of cathode current conduction, thereby maximizing the electroplating efficiency of PCB\FPC products and optimizing the uniformity quality. Reduce cost consumption.

[0038] (2) The clever mechanical structure design can reasonably distribute the friction resistance between the carrier and the conductive carbon brush during the moving operation, which can reduce the friction loss by about 40% and the power consumption of the carrier by about 10%, thus increasing the service life of the machine by 20%.

[0039] Through the copper-carbon brush group area, the copper-carbon brush plate 9 contacts the surface of the electroplated part to form a conductive connection. The current is transmitted from the power supply through the connecting plate 1 and the copper-carbon brush plate 9 to the surface of the electroplated part, and then a chemical reaction occurs in the electroplating solution to complete the electroplating process. The copper-carbon brush plate 9 moves inside the copper shell 7 through the spring 8. The movement and free contact of the copper-carbon brush plate 9 ensure that the current can be evenly distributed on the surface of the electroplated part, thereby achieving uniform electroplating. The copper-carbon brush plate 9 adopts a free contact design, which means that the brush group can slide inside the slide 13 through the spring 8 and the fixing bolt 10 according to the shape and surface conditions of the electroplated part, so that the contact position and strength can be freely adjusted. This design can ensure uniform current transmission on electroplated parts of different shapes and sizes, thereby avoiding the problem of uneven coating thickness caused by uneven current density. The cathode conductive free contact copper-carbon brush group of the continuous electroplating line ensures uniform transmission of current during the electroplating process through excellent conductive properties and free contact design, thereby achieving a uniform electroplating effect.
