Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to an automatic control device for the liquid level of electroplating tank chemicals based on ultrasound. Background Technology

[0002] In the electroplating production process, the stability of the solution level in the electroplating tank has a crucial impact on the quality of the electroplated products and production efficiency. If the solution level is too high, it is easy for the solution to overflow, which not only wastes the solution but may also corrode equipment and pollute the environment. If the solution level is too low, it will lead to instability in the electroplating process, affecting the uniformity and quality of the electroplated layer, and may even damage the electroplating equipment.

[0003] A patent document with publication number CN213690337U discloses an automatic high-purity water level control device. The device includes a raw water tank and a high-purity water tank. The lower end of the raw water tank is connected to a pure water treatment device via a connecting pipe and a first solenoid valve. The output end of the pure water treatment device is connected to the high-purity water tank via a connecting pipe and a pressure pump. The upper left side of the raw water tank is connected to the inlet pipe via a second solenoid valve. A raw water level detector is fixed to the inner wall of the raw water tank with bolts. A high-purity water level detector is also fixed to the inner wall of the high-purity water tank with bolts. The first solenoid valve, the pressure pump, the second solenoid valve, the pure water treatment device, the raw water level detector, and the high-purity water level detector are all connected to a control host via connecting lines.

[0004] Although the aforementioned high-purity water level automatic control device can solve the corresponding technical problems, its control accuracy is low and its reliability is poor during use, making it difficult to meet the needs of modern high-precision electroplating production. Therefore, there is still room for improvement.

[0005] To address this, an automatic control device for the liquid level of electroplating tank chemicals based on ultrasound is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 An embodiment of this utility model provides an automatic control device for the liquid level of electroplating tank chemicals based on ultrasound, including: a base 2 disposed on one side of the ultrasonic electroplating tank body 1, and a liquid adding mechanism 4, a controller 5 and an automatically adjusting liquid level lifting mechanism 3 disposed on the top of the base 2; wherein, the lifting mechanism 3 and the liquid adding mechanism 4 are electrically connected to the controller 5 through wires respectively.

[0023] The lifting mechanism 3 includes a bracket 301 fixed to the top of the base 2. A screw 302 is rotatably connected to the middle of the bracket 301, and a slider 304 is screwed onto the surface of the screw 302. A liquid control assembly is installed at one end of the slider 304. One end of the screw 302 is fixedly connected to the rotating shaft of a motor 303, which is fixedly mounted on the top of the bracket 301. By setting up the lifting mechanism 3, the motor 303 drives the screw 302 to rotate, thereby driving the slider 304 to move up and down. Under the control of the controller 5, it can adapt to ultrasonic electroplating tanks 1 of different sizes, thus greatly improving its flexibility of use.

[0024] The liquid filling assembly includes a pin 305 and a screw 307. The pin 305 is slidably inserted into one end of the slider 304. A float 306 is installed at the bottom of the pin 305, and a communicating vessel 309 is installed at the top of the pin 305. The screw 307 is fixedly installed on the top of the slider 304, and a positioner 308 is screwed onto the surface of the screw 307. By setting up the liquid filling assembly and installing the float 306 and communicating vessel 309 at both ends of the pin 305, and using it in conjunction with the positioner 308 on the surface of the screw 307, the liquid level of the chemical solution in the ultrasonic electroplating tank 1 can be replenished without frequent manual intervention, saving labor costs. It also improves the timeliness and accuracy of liquid level control, ensuring the stability of the chemical solution level during the electroplating production process.

[0025] The positioner 308 includes an upper positioner and a lower positioner, which work in conjunction with the communicating vessel 309. Positioners 308 and communicating vessel 309 are electrically connected to the controller 5 via wires. By using positioners 308 and communicating vessel 309 together, and adjusting the upper and lower positioners, the communicating vessel 309 moves between them. If the liquid level falls below the lower threshold, the controller 5 immediately sends a start signal to the liquid addition mechanism 4 to replenish the liquid.

[0026] The liquid addition mechanism 4 includes a liquid addition tank 401 and a water pump 402. The liquid addition tank 401 is fixedly installed on the top of the base 2. The inlet of the water pump 402 extends into the liquid addition tank 401 through a pipe, and the outlet of the water pump 402 extends into the ultrasonic electroplating tank 1 through an outlet pipe 403. The water pump 402 is electrically connected to the controller 5 through a wire. By setting up the liquid addition mechanism 4, it can automatically add liquid to the ultrasonic electroplating tank 1 under the control of the controller 5, which greatly improves the reliability and stability of the entire device and reduces equipment maintenance costs.

[0027] The liquid addition tank 401 is made of stainless steel. Stainless steel is corrosion-resistant, which can resist the corrosive effects of the liquid, and its smooth surface makes it easy to clean.

[0028] Among them, the controller 5 can be a Delta DVP14ES200R programmable logic controller; the positioner 308 can be a Schneider XCE145C adjustable limit switch.

[0029] The working principle of this utility model is as follows: In use, it is installed on one side of the ultrasonic electroplating tank 1. The lifting mechanism 3 and the liquid adding mechanism 4 are started by the controller 5. The positioner 308 on the adjusting screw 307 is used to determine the liquid adding range. The communicating vessel 309 moves between the positioners 308 under the drive of the float 306. When the communicating vessel 309 contacts the lower positioner 308, the controller 5 controls the liquid adding mechanism 4 to add liquid. When the communicating vessel 309 contacts the upper positioner 308, the controller 5 controls the liquid adding mechanism 4 to stop adding liquid. In this process, there is no need for frequent manual intervention, which saves labor costs and also improves the timeliness and accuracy of liquid level control, ensuring the stability of the liquid level in the electroplating process.

[0030] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
