Description

TECHNICAL FIELD

[0002] Raw foil generally refers to copper foil produced by electrolysis, which is widely used in electronic, electrical and construction industries, and is indispensable in printed circuit board manufacturing. In the production process of raw foil, the adding link of additives is crucial, and the adding amount, adding timing and adding precision directly affect the quality of raw foil, such as the thickness uniformity, surface smoothness and mechanical properties of raw foil.

[0003] At present, the adding of additives in raw foil production is mostly controlled manually or semi-automatically. The manual control method relies on the experience of the operator, and not only has high labor intensity, but also is difficult to accurately control the adding amount and rhythm of additives, which is prone to cause excessive or insufficient adding of additives due to human operation errors, thereby affecting the stability of the quality of raw foil products. The semi-automatic control method can reduce manual intervention to a certain extent, but mostly can only realize single-dose timed adding, and cannot dynamically adjust the adding amount of additives according to real-time parameters (such as electrolyte concentration, temperature, raw foil production speed, etc.) in the raw foil production process, which has poor adaptability and is difficult to meet the needs of high-quality raw foil production under different production conditions. More importantly, some existing adding devices also have the problem of uneven mixing of additives, and the additives cannot be quickly and uniformly dispersed after entering the electrolyte, and the local area has too high or too low concentration of additives, which will also adversely affect the production quality of raw foil. Therefore, it is urgent to propose an automatic raw foil additive control device to improve the above problems. SUMMARY

[0015] In summary, after adopting the above structure, the present application has the following advantages compared with the prior art: In the present application, the entire device relies on the synergistic effect of the central control element and the detection assembly to build a closed-loop control system of "real-time detection-intelligent calculation-accurate execution", solving the drawbacks of traditional manual or semi-automatic control. The electrolyte concentration sensor and the electrolyte temperature sensor can capture the key parameters of the electrolyte in the cyclone cylinder in real time, the foil production speed sensor synchronously acquires the production rhythm of the production line, and the liquid level sensor monitors the remaining amount of additives in the storage tank in real time. The central control element can quickly calculate the accurate amount of additives required under the current working condition based on these real-time signals, and then automatically control the operation of the conveying assembly and the quantitative assembly, effectively avoiding the problem of excessive or insufficient additives caused by manual experience operation, and significantly improving the stability of the foil product quality. In the present application, through the special design of the stirring mechanism and the cyclone cylinder, the bottleneck of slow dispersion and uneven local concentration in the traditional mixing method is broken, and the mixing effect is guaranteed. On the one hand, when the driver of the stirring mechanism drives the stirring shaft to rotate, the spiral blade in the storage tank and the stirring frame can pre-stir the additives to prevent stratification of the additives during the storage stage. On the other hand, the electrolyte inlet pipe and the additive inlet pipe on the top inner wall of the cyclone cylinder are installed in a "tangent" manner. After the electrolyte and the quantitatively conveyed additives enter the cyclone cylinder, they will form a high-speed cyclone along the cylinder wall, preliminarily realizing efficient mixing. At the same time, the rotation of the stirring shaft will also drive the rotating cylinder and the rotating disc to rotate through the connecting plate. The arc-shaped groove on the top of the rotating disc cooperates with the guide hole on the rotating cylinder to further divide and guide the mixed liquid. In combination with the anti-splashing effect of the annular retaining seat, the mixed liquid forms multidimensional flow and impact in the mixing tank, finally realizing deep and uniform fusion of the additives and the electrolyte, and avoiding the adverse effects of excessive or insufficient concentration of additives in local areas on the uniformity of foil thickness and the surface smoothness. In the present application, by setting the heating and heat preservation assembly and the anti-deposition assembly, the additives can always maintain the best state during storage and transportation. The heating and heat preservation assembly wraps the storage tank with the heat preservation shell and heats the gap between the storage tank and the heat preservation shell by using the electric heating pipe, so as to maintain the additives in the storage tank at an appropriate temperature, avoiding the increase of viscosity and poor flowability of the additives due to too low temperature, or the influence of temperature fluctuation on the chemical properties. The anti-deposition assembly rotates the driven gear through the rotation power of the stirring shaft, and then makes the traction rod pull the movable rod and the pull rod reciprocate in the air cylinder. When the pull rod drives the piston disc to move, the air cylinder can suck in air through the air inlet, and then spray the compressed air into the bottom of the storage tank through the air injection hole of the air injection pipe and the air injection frame, forming micro air bubbles to disturb the additives. In combination with the stirring effect of the stirring frame, the deposition and caking of the additives in the bottom of the storage tank are effectively prevented, the composition of the additives is uniform, and the deposition of the additives is avoided to block the pipeline or affect the adding accuracy.
