Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic copper foil automation, and particularly to an automatic proportioning and conveying system for high-precision multi-component additives. Background Art

[0002] In the electrolytic copper foil industry, for the preparation of high-precision multi-component additives, currently, methods such as manual weighing, manual stirring and dissolving, and manual feeding are mostly used. For factories with large production volumes and harsh environments, this method not only has extremely high manual labor intensity, low work efficiency, but also has the risk of metering errors. The dosage of additives plays a crucial role, and the demand for its high-precision dosage and the harsh workshop environment have caused great difficulties for the automatic preparation and conveying of copper-dissolving additives. At present, for the copper foil industry, the research status of the automatic proportioning and conveying system for high-precision multi-component additives is relatively less mentioned. However, with the continuous development of intelligent and automated technologies, the automatic proportioning and conveying system for high-precision multi-component additives will become more intelligent and automated.

[0003] Currently, for the preparation of high-precision multi-component additives, methods such as manual weighing, manual stirring and dissolving, and manual feeding are often required. This method not only has extremely high manual labor intensity, extremely low efficiency, but also has the risk of metering errors. And some solid additives need to be dissolved at high temperatures, and there is a risk of high-temperature burns to personnel.

[0004] In addition, only two groups of additive hoppers are provided, and only the mixed conveying of two kinds of powder additives can be realized; the copper foil industry has extremely high requirements for the dosage accuracy of additives. Affected by the harsh environment of the copper-dissolving workshop, it is extremely difficult to achieve extremely high-precision weighing with a weighing sensor; and the control accuracy of the plug valve is relatively low, and high-precision weighing cannot be achieved. Moreover, the current research status of the automatic proportioning and conveying system for high-precision multi-component additives is relatively less mentioned, and the degree of automation is low. Introducing the automatic proportioning and conveying system for high-precision multi-component additives will greatly improve the intelligent and automated level of related fields.

[0020] The present invention aims to improve the working efficiency of preparing high-precision multi-component additive solutions and reduce the labor intensity of on-site operators. As Figure 1-2 shown, the following technical solutions are provided: A high-precision multi-component additive automatic proportioning and conveying system includes a raw material processing part, a conveying part, and a control part. The raw material processing part includes multiple general-purpose additive barrels 1, multiple high-precision additive barrels 2, a solid hopper 13, a first transfer tank 4 connected to the multiple general-purpose additive barrels 1, and a second transfer tank 8 connected to the multiple high-precision additive barrels 2.

The conveying part includes a conveying switch valve 22 connected to the outlets of the first transfer tank 4, the second transfer tank 8, and the third transfer tank 21. The conveying switch valve 22 is connected to the feeding switch valves 23 of each dosing system through pipelines. Weighing components are installed on the first transfer tank 4, the second transfer tank 8, and the solid material conveying device. An electric tracing heating module 19 is installed on the third transfer tank 21. The control part is electrically connected to the raw material switch valve 24, the high-precision metering pump 3, the conveying switch valve 22, the feeding switch valve 23, the weighing component, and the electric tracing heating module 19. By introducing a high-precision multi-component additive automatic proportioning and conveying system, the automation level of the industry is improved. Moreover, multi-barrel partition feeding is adopted to effectively solve the problem of single additive batching, realize multi-component additive batching, and multiple transfer tanks are equipped with weighing components to achieve high-precision weighing.

[0021] Specifically, the quantities of the general-purpose additive barrel 1 and the high-precision additive barrel 2 can be expanded as needed. The general-purpose additive barrel 1 and the high-precision additive barrel 2 are classified according to the types and functions of the additives. The dosage of the additives in the general-purpose additive barrel 1 is relatively large, and it needs to be formulated into an additive solution during use. Therefore, pure water needs to be added to the first transfer tank 4 and stirred by setting the first stirrer 5. The stirred general-purpose additive solution can be controlled by the transfer switch valve 22 and discharged into the feed switch valve 23 corresponding to each dosing line. The feed switch valve 23 can control the opening and closing of each line. A high-precision weighing sensor 7 is installed on the first transfer tank 4. The high-precision weighing sensor is electrically connected to the control part, which can improve the weighing accuracy and transmit the collected weight data to the control part, so that the general-purpose additives added to the general-purpose additive barrel 1 can be monitored in real time for their weights.

[0022] Various additives that require precise dosage control can be placed in the high-precision additive barrel 2. The additives that require precise dosage control enter the second transfer tank 8. The second transfer tank 8 is installed on the second weighing scale 9, and the changes in the additives in the second transfer tank 8 can be monitored in real time through the second weighing scale 9, and cooperate with the transfer switch valve 22 to add the additives that require precise dosage control to the feed switch valve 23. The automatic preparation of the high-precision multi-component additive solution improves the degree of intelligence and automation in related fields of the industry.

[0023] The first stirrer 5 and the second stirrer 20 are respectively installed in the first transfer tank 4 and the third transfer tank 21. By setting stirrers in the first transfer tank 4 and the third transfer tank 21, mechanical energy is provided to ensure the full dissolution of the solid additives and the general-purpose additives.

[0024] The solid hopper 13 is used to place solid additives. An electric control valve 15 electrically connected to the control part is installed at the lower outlet of the solid hopper 13. The electric control valve is used to realize the feeding of the solid additives, effectively solving the problems of low precision and poor controllability of the flap valve. A screw feeder 14 is installed in the solid hopper 13, and the screw feeder 14 can transport the solid additives towards the electric control valve 15 while stirring the solid additives.

[0025] In this embodiment, as Figure 1As shown, the raw material processing part also includes a hot water tank 11 connected to the third transfer tank 21, and an electric heating module 12 is provided in the hot water tank 11. A high-precision flow meter 25 is provided on the pipeline between the hot water tank 11 and the third transfer tank 21. The electric heating module 12 and the high-precision flow meter 25 are both electrically controlled and connected to the control part. In addition to providing heat energy for the solid additive through the hot water in the hot water tank 11, the third transfer tank 21 is also provided with an electric heating module for secondary heat energy, and effectively solves the risk of personnel being scalded by high temperature. The first transfer tank 4, the second transfer tank 8, the third transfer tank 21 and the hot water tank 11 are all connected to pure water through pipelines. At the same time, the first transfer tank 4 and the third transfer tank 21 are both provided with a spray component 6 connected to pure water. The spray component 6 can fully rinse the additives inside the first transfer tank 4 and the third transfer tank 21 to ensure sufficient delivery of the solution.

[0026] In order to facilitate the control of various raw materials, the universal additive barrel 1, the high-precision additive barrel 2 and the hot water tank 11 are all equipped with a liquid level meter 10, and the liquid level meter 10 is electrically connected to the control part. When the raw material in the container is lower than the liquid level meter 10, the system can automatically add the raw material to the corresponding container.

[0027] In this embodiment, the solid material conveying device includes a first scale 17 arranged below the discharge port of the solid hopper 13 and a robotic arm conveying device 18 arranged on one side of the first scale 17. The robotic arm conveying device 18 conveys the solid material conveying tank 16 on the first scale 17 to the third transfer tank 21 for dumping. The solid additive unloading is provided with a solid material conveying tank 16, which cooperates with the first scale 17 to achieve precise weighing, and is provided with a robotic arm conveying device 18 to realize automatic unloading of the solid additive at a fixed point and ensure the stability of the unloading accuracy.

[0028] In this embodiment, the universal additive barrel 1, multiple high-precision additive barrels 2, solid hopper 13, first transfer tank 4, second transfer tank 8 and third transfer tank 21 are all arranged on the upper side of the industrial platform, and the conveying part is arranged on the lower side of the industrial platform to facilitate the operation and adjustment of the equipment on the upper side of the industrial platform.

[0029] All the above-mentioned barrels and transfer tanks can be expanded and set at high positions to meet the requirements of additive dosing of more components and realize gravity transportation. The transportation part is transported to each dosing system by gravity through the opening and closing of the switch valve, in conjunction with the liquid level gauge and pneumatic switch valve of each dosing system, and finally flushed with pure water to ensure the adequacy of the additive solution transportation.

[0030] The control part may include a programmable controller, an industrial control host computer, a control point module, etc., to achieve the automatic control and real-time monitoring of the whole machine system. By introducing a real-time monitoring system, the on-site situation can be understood in the office without frequent on-site inspections. Through the mutual adjustment and cooperation of the various parts of the present invention, the purpose of accurate batching and conveying is finally achieved.
