Description

Technical Field

[0001] The utility model relates to the technical field of dot plating wheels, and particularly relates to a dot plating wheel for a dot plating machine. Background Art

[0002] Dot plating equipment is electroplating equipment for electronic components. In order to ensure the electrical performance of the contacts of electronic components, precious metals are usually dot plated on the contacts of electronic components. Also, since the contacts of electronic components are usually small and are usually punched in the form of a strip before assembly, a wheel type dot plating machine has emerged. In order to improve the accuracy of dot plating, different dot plating wheels are usually designed according to different products, so as to facilitate the accurate guiding of the strip and ensure that the nozzle is in one-to-one correspondence with the dot plating area of the strip. However, the above method makes the dot plating wheel only applicable to one kind of strip, and different dot plating wheels need to be prepared for different kinds of strips, which leads to a high use cost of the dot plating wheel.

[0003] In the patent document with the authorized publication number of CN220665487U, a dot plating wheel and a dot plating assembly for a dot plating machine are disclosed. A dot plating wheel for a dot plating machine includes a fixed ring, a filling ring and two nozzle slip rings. Nozzle flexible rings are provided at opposite ends of the two nozzle slip rings. A nozzle orifice is formed between the two nozzle flexible rings. A nozzle guide rod is provided between the two nozzle slip rings. The axis of the nozzle guide rod is parallel to the axis of the fixed ring. The nozzle slip ring is in sliding fit with the nozzle guide rod. A nozzle adjustment stud is in threaded fit with the nozzle slip ring. One end of the nozzle adjustment stud abuts against the end of the nozzle guide rod. Chute grooves are provided on the outer circumferences of the filling ring and the nozzle slip ring. Sliding blocks are provided in the chute grooves. Belt guide rings are sleeved on the outer sleeves of the filling rings on both sides of the nozzle orifice. Connecting screws are provided on the belt guide rings. A main guide rod is provided between the two fixed rings. A locking screw is provided on the fixed ring. A locking nut is provided on the nozzle slip ring, which can adjust the position and width of the nozzle orifice, so that a dot plating wheel is applicable to strips of different specifications and dot plating areas of different widths, effectively reducing the use and spare costs of the dot plating wheel.

[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution: a plating wheel for a plating machine, including a wheel frame 1, the wheel frame 1 is arranged in an I shape, a plurality of groups of through holes 2 are opened on the outer surface of the wheel frame 1, the plurality of groups of through holes 2 are evenly arranged in a circular array, both ends of the wheel frame 1 are respectively installed with wheel discs 3 through a plurality of groups of bolts, a plurality of groups of mounting frames 4 are respectively installed on the inner walls of the two wheel discs 3, the plurality of groups of mounting frames 4 are arranged in a circular array, mixing fan blades 5 are respectively rotatably installed on both sides of the plurality of groups of mounting frames 4, snap rings 6 are respectively installed on the inner sides of the two wheel discs 3, annular grooves are respectively opened on one side of the two snap rings 6 facing each other, and a filter ring 7 is clamped inside the snap rings 6 located inside the two annular grooves.

[0030] In the technical solution of the present utility model, the wheel disc 3 can be fixed by the wheel rim 1, the mounting bracket 4 can be fixed by the wheel disc 3, the mixing fan blades 5 can be rotatably mounted by the mounting bracket 4. When the wheel rim 1 rotates, the electroplating solution inside the wheel rim 1 can drive the mixing fan blades 5 to rotate when rotating, and when the mixing fan blades 5 rotate, they can mix the electroplating solution, enhancing the mixing effect of the electroplating solution in each area inside the wheel rim 1.

[0031] In addition, the snap ring 6 can be fixed by the setting of the wheel disc 3, and the filter ring 7 can be clamped by the snap ring 6.

[0032] In the technical solution of the present utility model, as Figure 1 shown, two belt guide rings 8 are fixedly installed on the outer wall of the wheel rim 1. By setting the belt guide rings 8, it is convenient for the belt of the external device to drive the wheel rim 1.

[0033] In the technical solution of the present utility model, as Figure 1 shown, the belt guide rings 8 are made of stainless steel. By making the belt guide rings 8 of stainless steel, the corrosion resistance of the belt guide rings 8 can be enhanced.

[0034] In the technical solution of the present utility model, as Figure 1 shown, mounting shafts 9 are installed on the inner walls of the two wheel discs 3. By setting the mounting shafts 9, the wheel discs 3 can be installed with the external electroplating machine. A semi-circular disc 10 is installed on the outer wall of the mounting shaft 9 on one side of one of the wheel discs 3. By setting the semi-circular disc 10, it is convenient to install the wheel disc 3.

[0035] During use, first, the electroplating wheel can be installed on the electroplating machine to ensure that the mounting shaft 9 is correctly connected to the drive system of the electroplating machine. Check and install the filter ring 7 to ensure that the filter ring 7 is correctly clamped in the two annular card slots to filter impurities in the electroplating solution. Check whether the through holes 2 on the outer surface of the wheel rim 1 are unobstructed and not blocked to ensure that the mixing fan blades 5 can rotate freely on the mounting bracket 4;

[0036] Ensure that the electroplating solution can cover the wheel discs 3 and the wheel rim 1 and flow through the through holes 2. Start the external electroplating machine to drive the electroplating wheel to start rotating. As the electroplating wheel rotates, the electroplating solution will form a thin film on the surface of the wheel disc 3 under the action of centrifugal force and circulate through the through holes 2 at the same time;

[0037] Since multiple groups of mounting brackets 4 are installed on the inner wall of the wheel disc 3 and the mixing fan blades 5 are rotatably installed on both sides of the mounting brackets 4, as the wheel disc 3 rotates, the mixing fan blades 5 will stir the electroplating solution. The stirring effect can ensure that the components in the electroplating solution are evenly distributed, preventing some components from having too high or too low concentration in local areas;

[0038] During the circulation process of the electroplating solution, it will be filtered through the filter ring 7 between the snap ring 6 inside the two discs 3 and the annular groove. The filter ring 7 can remove impurities and particulate matters in the electroplating solution, ensuring the purity of the electroplating solution;

[0039] The two belt guide rings 8 fixed on the outer wall of the wheel frame 1 are used to connect the transmission belt. Through the belt guide ring 8, the rotational power of the electroplating wheel is transmitted to other components or systems such as the circulation pump of the electroplating solution, ensuring that an effective circulating flow can be formed between the inside and outside of the electroplating wheel. After completing the electroplating task, it is necessary to turn off the electroplating machine and stop the rotation of the electroplating wheel; clean the residual electroplating solution and impurities inside the electroplating wheel to keep the electroplating wheel clean and intact. Through the above work process, the electroplating wheel of this electroplating machine can ensure that the electroplating solution is fully stirred and circulated during use, thereby maintaining the uniformity and stability of the electroplating solution and improving the electroplating quality and efficiency.
