DETAILED DESCRIPTION

[0021] The embodiments of the present invention are described in detail below. Figure 1 The embodiment of the utility model provides an online liquid medicine sampling device, including a sampling tank 200, one end of the sampling tank 200 is connected to the liquid medicine circulation pipeline 100 of the electroplating equipment, and the other end is connected to the liquid medicine management tank 300 of the electroplating equipment, that is, when the liquid medicine of the electroplating equipment flows back from the electroplating tank to the liquid medicine management tank 300, it needs to pass through the sampling tank 200. A cooling device 210 is provided in the sampling tank 200, and the cooling device 210 is used to cool the liquid medicine in the cooling tank to a suitable temperature required for detecting pH value and specific gravity, such as below 30 degrees Celsius.

[0022] The online liquid medicine sampling device of the embodiment of the utility model can make a certain amount of liquid medicine in the sampling tank 200 by controlling the speed of liquid medicine entering and exiting the sampling tank 200, so that the sampling tank 200 can be filled with a certain amount of liquid medicine, which is convenient for the inspection personnel to take out an appropriate amount of liquid medicine from the sampling tank 200 to measure the specific gravity and pH value, and ensure that the pH value and effective component content of the liquid medicine in production meet the process requirements. Sampling from the sampling tank 200 does not need to open the liquid medicine management tank 300, so as to avoid the inspection personnel from contacting with a large amount of liquid medicine and causing damage to the body of the inspection personnel. At the same time, the operation process is simplified to avoid the leakage and loss of high-value liquid medicine due to improper operation of the inspection personnel. The cooling device 210 cools the liquid medicine in the liquid collection tank to the temperature required for detection, so as to avoid the need for the inspection personnel to let the sample stand and cool down after sampling. At the same time, the probe of the pH detector can be directly inserted into the sampling tank 200 to directly read the pH value of the liquid medicine at a suitable temperature, saving the inspection personnel's detection operation time, improving the inspection personnel's work efficiency, and reducing the investment of human resource costs in the inspection process.

[0023] Reference Figure 2 In some embodiments, in order to prevent the liquid medicine in the sampling slot 200 from being full and overflowing due to the outflow rate of the liquid medicine being much lower than the inflow rate due to abnormal reasons, the sampling slot 200 is disposed in an anti-overflow slot 220. The height of the sampling slot 200 is lower than the height of the anti-overflow slot 220. The anti-overflow slot 220 is connected to the liquid medicine management slot 300 of the device. When the liquid medicine in the sampling slot 200 overflows due to abnormal reasons, the liquid medicine will overflow into the anti-overflow slot 220 and flow back into the liquid medicine management slot 300 through the overflow pipe 222 on the anti-overflow slot 220 that is connected to the liquid medicine management slot 300, thereby preventing the liquid medicine from overflowing from the sampling slot 200 to the outside of the device. Figure 2 In this embodiment, the side wall of the sampling tank 200 is connected to the liquid medicine circulation pipeline 100 of the equipment through the liquid inlet pipe, and the bottom of the sampling tank 200 is connected to the liquid medicine management tank 300 through the liquid outlet pipe. The liquid inlet pipe and the liquid outlet pipe are both provided with a pressure reducing valve 110 for adjusting the speed and pressure of the liquid medicine flowing in and out. In this embodiment, a two-stage pressure reducing valve 110 is provided on the liquid inlet pipe to gradually adjust the flow rate and pressure of the liquid medicine. The bottom and side wall of the anti-overflow tank 220 are both provided with overflow ports. After the two overflow ports are merged with the liquid outlet pipe through two overflow pipes 222, they are connected to the liquid medicine management tank 300 together. The two overflow pipes 222 of the anti-overflow tank 220 can improve the efficiency of returning the liquid medicine in the anti-overflow tank 220 to the liquid medicine management tank 300, and further prevent the liquid medicine from overflowing from the anti-overflow tank 220 to the outside of the equipment. The anti-overflow tank 220 is connected to the side wall of the liquid medicine management tank 300 through a transparent tube support 310 , and the liquid outlet pipe is arranged inside the transparent tube support 310 .

[0024] In order to prevent the liquid medicine in the sampling tank 200 and the anti-overflow tank 220 from evaporating into the air, refer to Figure 2 In this embodiment, the upper end of the anti-overflow groove 220 is provided with an openable and closable cover plate 221. When inspection is required, the specific gravity glass measuring tube 410 and the pH meter probe 420 are inserted into the sampling groove 200, and a small amount of liquid sample is taken out to measure the specific gravity of the liquid, and the pH value of the liquid is read out by the pH detector. In order to facilitate the observation of the liquid content in the liquid collection groove and the liquid management groove 300, in this embodiment, the liquid collection groove and the anti-overflow groove 220 are made of corrosion-resistant transparent materials, and the cover plate 221 is also made of the same transparent material as the anti-overflow groove 220, so that the liquid level in the sampling groove 200 can be directly observed from the outside, which is convenient for sampling.

[0025] It is understandable that the cooling device 210 can use semiconductor refrigeration or cooling liquid principle to cool the liquid medicine in the sampling tank 200. Figure 2 In this embodiment, the cooling device 210 includes a cooling tube 211 and a coolant circulation mechanism. The cooling tube 211 is arranged in a spiral shape from top to bottom along the side wall of the sampling tank 200, so as to increase the contact area between the coolant in the cooling tube 211 and the medicine solution and improve the cooling efficiency. The inlet and outlet of the cooling tube 211 are both close to the upper end of the sampling tank 200, and the cover plate 221 is provided with through holes for the inlet and outlet of the cooling tube 211 to pass through. The coolant circulation mechanism is used to dissipate the heat and cool the coolant flowing out of the outlet of the cooling tube 211, and then send it back to the cooling tube 211 through the inlet of the cooling tube 211, including necessary pipes, water pumps, compressors or condensers and other structures. Its specific structure is common knowledge in the field and will not be described here.

[0026] Reference Figure 3In order to save the time of inspectors in sending samples to the fixed inspection station and further improve the inspection efficiency, the online liquid sampling device also includes a detection cart 400, which is provided with a bracket for placing detection instruments and detection tools to place beakers, specific gravity glass measuring tubes 410 and pH detectors, etc. During inspection, the inspectors can push the inspection cart 400 to conduct patrol inspections along each electroplating production line to avoid the process of inspectors taking samples from the sampling slots 200 on each production line and sending them back to the fixed inspection station for testing, and then sending them back to the original sampling slots 200 to pour back the samples. In order to extend the working time of detection instruments such as pH detectors, the detection cart 400 is also provided with a battery 430 for powering the detection instruments.

[0027] The electroplating equipment of the embodiment of the utility model includes the above-mentioned online liquid medicine sampling device, and the sampling tank 200 is arranged on the circulation pipeline from the electroplating tank to the liquid medicine management tank 300, which is convenient for the pH value detection and specific gravity detection of the liquid medicine during inspection, and can improve the inspection efficiency of the electroplating equipment and the safety of the inspection process, reduce the input of inspection human resources, and improve production efficiency.
