Description

Technical Field

[0001] This invention relates to the field of continuous electroplating production line technology, and in particular to a rotary continuous partial electroplating production line. Background Technology

[0002] Currently, the vast majority of continuous electroplating production lines on the market adopt a linear layout, where all functional tanks are arranged in a straight line according to the process sequence. This layout has the advantages of clear logic and simple and intuitive material conveying paths, and it is a traditional design that has been in place for a long time.

[0003] However, with rising land costs in the manufacturing sector and increasing demands from enterprises for intensive and lean production, this traditional linear layout has revealed its inherent and serious flaws: it imposes stringent requirements on the spatial shape of the production workshop and is only efficiently applicable to long and narrow factory buildings. For more common rectangular or near-square industrial plants, this layout leads to significant space waste. A detailed analysis follows: Space utilization is severely underutilized: In rectangular workshops, a straight production line tens or even hundreds of meters long can only occupy a strip of space in the middle of the factory. Large areas of valuable space on both sides of the production line cannot be effectively utilized, resulting in a sharp decline in the utilization rate of the factory's floor space. This is equivalent to the company paying expensive rent or construction costs for a large amount of "idle" space that cannot be used for core production.

[0004] This limits the multi-functional planning of the workshop: the long and narrow open spaces formed on both sides of the production line are often difficult to plan for other auxiliary functions (such as raw material storage, semi-finished product buffer, quality inspection and packaging area, etc.) because these areas are physically divided by the production line, the logistics flow is not smooth, and the overall utilization efficiency of the entire workshop is further reduced.

[0005] The material transport path is long and the energy consumption is high: the linear layout means that the workpiece must traverse the entire length of the production line from the upper line point to the lower line point. The long running distance of the conveyor mechanism leads to unnecessary energy consumption and equipment wear.

[0006] The production line lacks flexibility: When it is necessary to expand production or add new processes, the linear layout can usually only be achieved by extending the production line, which will place higher demands on the length of the workshop and result in poor flexibility.

[0007] Therefore, there is an urgent need in this field for an innovative layout scheme for continuous electroplating production lines. This scheme should break through the constraints of the traditional linear layout, better adapt to factory buildings of various shapes, and in particular, significantly improve the space utilization rate in rectangular factory buildings, while ensuring the smooth, reliable, and efficient operation of the production process, so as to meet the urgent needs of modern manufacturing for intensive use of production space. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a continuous local electroplating rotary production line that can perform S-shaped bends to save workshop length space and can realize local electroplating.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a continuous partial electroplating rotary production line, including a frame, a plurality of rectangular electroplating tanks mounted on the frame, an electrolytic tank, and a surface treatment control device disposed above the rectangular electroplating tanks. The frame is equipped with a rotatable partial electroplating roller, which is located at one end of the frame. The plurality of rectangular electroplating tanks are located on the outer tangent of the partial electroplating roller. When the roll material is wound on the roller, the roll material passes through each rectangular electroplating tank. The frame is equipped with an arc-shaped electroplating tank that is concentric with the partial electroplating roller. The arc-shaped electroplating tank is spliced ​​with multiple rectangular electroplating tanks to form a U-shape, and the partial electroplating roller is located inside the arc-shaped electroplating tank. The outer circumferential surface of the partial electroplating roller is provided with an inserting annular groove corresponding to the width of the roll strip. During continuous electroplating, the roll strip is wound around the inserting annular groove. A radially penetrating annular groove is provided in the middle of the inserting annular groove. The position of the annular groove corresponds to the partial electroplating area of ​​the roll strip.

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0023] like Figures 1 to 4As shown, a continuous partial electroplating rotary production line includes a frame 1, multiple rectangular electroplating tanks 11 mounted on the frame 1, an electrolytic tank, and a surface treatment control device 3 disposed above the rectangular electroplating tanks 11. The frame 1 is characterized by having a rotatable partial electroplating roller 4 located at one end of the frame 1. The multiple rectangular electroplating tanks 11 are located on the outer tangent of the partial electroplating roller 4. When the feed strip is wound around the roller, the feed strip passes through each rectangular electroplating tank 11. An arc-shaped electroplating tank 12 is concentrically arranged with the partial electroplating roller 4. The arc-shaped electroplating tank 12 is spliced ​​with multiple rectangular electroplating tanks 11 to form a U-shape. The partial electroplating roller 4 is located inside the arc-shaped electroplating tank 12. The outer circumferential surface of the partial electroplating roller 4 is provided with an inserting annular groove 41 corresponding to the width of the roll strip. During continuous electroplating, the roll strip is wound around the inserting annular groove 41. A radially penetrating annular groove 42 is provided in the middle of the inserting annular groove 41. The position of the annular groove 42 corresponds to the partial electroplating area of ​​the roll strip.

[0024] In practical applications, the rectangular electroplating tank 2 and the electrolytic tank are arranged according to the electroplating process, and the turning and bending are realized at the position of the arc electroplating tank 2. The design of the partial electroplating roller 4 is equivalent to the idler wheel structure, realizing the turning function of the production line and the electroplating roll, thereby realizing the S-shaped layout of the continuous electroplating production line. This scheme can break through the constraints of the traditional straight layout and can better adapt to factories of various shapes. In particular, it can significantly improve the space utilization rate in rectangular factories, while ensuring the smoothness, reliability and efficiency of the production process, so as to meet the urgent needs of modern manufacturing industry for intensive use of production space. It is highly practical.

[0025] The design of the partial electroplating roller 4 allows for partial gold plating only on the conductive parts of the electroplating terminal, without requiring the entire terminal to be immersed in liquid gold plating. This significantly reduces the amount of gold plating chemicals and electroplating costs, greatly improving cost-effectiveness and resulting in significant economic benefits.

[0026] In this embodiment, the partial electroplating roller 4 includes an upper cylinder 43 and a lower cylinder 44 of the same size as the upper cylinder 43. The upper cylinder 43 and the lower cylinder 44 are arranged in parallel at intervals to form the annular through groove 42.

[0027] During continuous electroplating, the coil strip is embedded in the inserting annular groove and rotates continuously. During the electroplating process, the gold plating solution is only immersed up to the annular groove, which is used for local electroplating of the lower half of the coil strip. At the same time, due to the design of the annular groove 42, double-sided gold plating can be achieved in the middle of the coil strip, and the middle perimeter of the terminals on the coil strip can also be electroplated. This achieves continuous and precise electroplating of designated positions on the coil strip. While meeting the gold plating requirements, less chemical is used, resulting in higher cost performance.

[0028] In this embodiment, the lower end face of the upper cylinder 43 is provided with a plurality of connecting pins 45 axially, and the upper end face of the lower cylinder 44 is provided with a plurality of adjusting holes 46 corresponding to the connecting pins 45. The wheel surface of the lower cylinder 44 is provided with grommets 47. When the connecting pins 45 are inserted into the adjusting holes 46 and the width of the inserting ring groove 41 is adjusted, the upper cylinder 43 and the lower cylinder 44 can be assembled and fixed by the grommets 47.

[0029] By adjusting the depth of the connecting pin 45 within the adjusting hole, the distance between the upper cylinder 43 and the lower cylinder 44 can be adjusted, thereby achieving the width of the inserting annular groove 41 and the annular through groove 42 to accommodate different widths of coiled strip. The adjustment operation is simple and highly practical.

[0030] In Embodiment Two, the difference from Embodiment One is that: the lower end face of the upper cylinder 43 and the upper end face of the lower cylinder 44 are each provided with multiple corresponding adjustment holes 46. The two ends of the connecting pin 45 are respectively inserted into the corresponding adjustment holes 46 of the upper cylinder 43 and the lower cylinder 44. Both the upper cylinder 43 and the lower cylinder 44 are provided with grommets 47. After the two ends of the connecting pin 45 are inserted into the adjustment holes 46 and the width of the locating ring groove 41 is adjusted, the upper cylinder 43 and the lower cylinder 44 can be assembled and fixed using the grommets 47. The design of the double adjustment holes 46 on the upper cylinder 43 and the lower cylinder 44 increases the range of adjustment for their spacing, thereby significantly improving the applicability of the partial electroplating roller 4 and enhancing its practicality.

[0031] In this embodiment, a chemical return tank 5 and a spraying device for spraying electroplating chemicals onto the coil and the local electroplating roller 4 are provided below the frame 1 to realize the electroplating process.

[0032] In this embodiment, a housing cabinet 6 is provided above the middle of the frame 1. The housing cabinet 6 is 1.6-1.7 meters above the ground. The surface treatment control device 3 is located inside the housing cabinet 6. Specifically, the surface treatment control device 3 is equipped with a display screen 31 for displaying the voltage, current, or frequency during electroplating or electrolysis. Operators can intuitively observe and understand the electroplating parameters when inspecting and maintaining the electroplating production line, and can adjust the current electroplating parameters through the surface treatment control device 3. It is simple, convenient, and highly operable.

[0033] In this embodiment, the partial electroplating roller 4 is made of hard insulating plastic, which reduces the wear of the electroplating roll strip by the partial electroplating roller 4 and does not affect the smooth progress of the electroplating operation, thus ensuring high reliability.

[0034] In Embodiment Two, the difference from Embodiment One is that: the lower end face of the upper cylinder 43 and the upper end face of the lower cylinder 44 are each provided with multiple corresponding adjustment holes 46. The two ends of the connecting pin 45 are respectively inserted into the corresponding adjustment holes 46 of the upper cylinder 43 and the lower cylinder 44. Both the upper cylinder 43 and the lower cylinder 44 are provided with grommets 47. After the two ends of the connecting pin 45 are inserted into the adjustment holes 46 and the width of the locating ring groove 41 is adjusted, the upper cylinder 43 and the lower cylinder 44 can be assembled and fixed using the grommets 47. The design of the double adjustment holes 46 on the upper cylinder 43 and the lower cylinder 44 increases the range of adjustment for their spacing, thereby significantly improving the applicability of the partial electroplating roller 4 and enhancing its practicality.
