Description

Technical Field

[0001] The invention belongs to the field of product cleaning lines, and in particular relates to an intelligent product cleaning line. Background Art

[0002] In the process of CNC machining, cutting fluid is usually used to reduce cutting force, reduce cutting temperature, improve tool life and workpiece surface quality. The cutting fluid interacts with the tool, workpiece and chips in the cutting area to form an oil film or emulsion film to prevent direct contact and friction between the tool and the workpiece. However, the cutting fluid may splash or evaporate during the machining process, and some of it may remain on the surface of the product to form oil stains. In some machining processes, lubricants may also be required to further reduce friction and wear. These lubricants may also leave oil stains on the surface of the product. Therefore, after the product is machined, it needs to be cleaned through a cleaning line to remove the oil stains generated by cutting fluids and lubricants. However, due to the difficulty of removing oil stains, a large amount of water will be consumed in this process, resulting in a waste of water resources. Therefore, it is necessary to improve the existing cleaning line and advance the degree of intelligence to save water for cleaning products. Summary of the invention

In this embodiment, in order to facilitate the separate control of the first cleaning unit and the second cleaning unit, two detection control units are provided, namely: a first detection control unit and a second detection control unit, the first detection control unit is used to detect the concentration of the agent in the first cleaning unit, and according to the concentration of the agent, the drug supply unit adds the agent to the first cleaning unit or the first water supply unit adds water to the first cleaning unit; the second detection control unit is used to detect the conductivity of the water in the second cleaning unit, and control the water supply rate of the second water supply unit to the second cleaning unit according to the detection result. Of course, the first detection control unit and the second detection control unit can also be combined into one detection control unit, and the detection control unit has all the functions of the first detection control unit and the second detection control unit.

[0054] Please continue reading Figure 1 In this embodiment, the first cleaning unit includes a medicine tank 101 for storing medicine and ultrasonically cleaning products immersed in the medicine, a mixing tank 102 for mixing the liquid inside the medicine tank 101, and a replacement device for replacing the medicines in the medicine tank 101 and the mixing tank 102. The medicine supply unit includes a medicine barrel 111 and a medicine adding motor 112 for adding the medicine in the medicine barrel 111 to the mixing tank 102; the first water supply unit includes a first water supply pipe 310 connecting the water source 300 and the mixing tank 102, and a first flow meter 311 and a solenoid valve 312 arranged in series on the first water supply pipe 310. Figure 1 The dotted lines in the figure represent control cables.

[0055] The replacement device may include a first water pump 103 that pumps the medicine in the lower part of the medicine tank 101 into the mixing tank 102 and a second water pump that pumps the medicine in the mixing tank 102 into the medicine tank 101. Figure 2 In order to save costs, the mixing tank 102 can also be installed on the upper part of the medicine tank 101, and the replacement device can also include a first water pump 103 that pumps the medicine at the lower part of the medicine tank 101 into the mixing tank 102 and an injection port 104 that connects the upper part of the mixing tank 102 with the medicine tank 101, so that the medicine in the mixing tank 102 can be automatically injected into the medicine tank 101 from the injection port 104 at the upper part of the mixing tank 102, thereby omitting one water pump.

[0056] See also Figure 3The first detection control unit includes a first control module 510 and a concentration sensor 511 arranged in the medicine tank 101, and the concentration sensor 511, the dosing motor 112, the solenoid valve 312 and the first flow meter 311 are all electrically connected to the first control module 510; the first control module 510 is used to detect the concentration of the medicine in the medicine tank 101 through the concentration sensor 511, and when the concentration of the medicine is lower than the preset concentration value range, the dosing motor 112 works for a predetermined time to add medicine to the mixing tank 102; the first control module 510 is also used to open the solenoid valve 312 when the concentration of the medicine is higher than the preset concentration value range, add water to the mixing tank 102, and determine the amount of water to be added according to the concentration value, and detect the amount of water added through the first flow meter 311, and close the solenoid valve 312 when the amount of water added reaches the preset amount of water.

[0057] Please continue reading Figure 1 , the second cleaning unit includes a plurality of spray tanks arranged in sequence and auxiliary tanks connected to the spray tanks in a one-to-one correspondence. In this embodiment, a five-stage spray tank structure is adopted, and spray tank 201, spray tank 202, spray tank 203, spray tank 204 and spray tank 205 are provided. Among them, spray tank 201 is a first-stage spray tank, connected to auxiliary tank 211; spray tank 202 is a second-stage spray tank, connected to auxiliary tank 212; spray tank 203 is a third-stage spray tank, connected to auxiliary tank 213; spray tank 204 is a fourth-stage spray tank, connected to auxiliary tank 214; spray tank 205 is a fifth-stage spray tank, connected to auxiliary tank 215. Since the water level in the auxiliary tank will decrease when not used for a long time, thereby affecting the cleaning effect, the present embodiment also provides a liquid level sensor 526 in the auxiliary tank 211 (i.e., the auxiliary tank of the first-stage spray tank) to detect whether the water in the auxiliary tank 211 meets the cleaning requirements before cleaning.

[0058] Each of the spray tanks is provided with a spray device 231, which is used to draw water from the corresponding auxiliary tank to rinse the product inside the spray tank. The auxiliary tank is located lower than the spray tank, and the upper part of the auxiliary tank is connected to the lower part of the spray tank. Figure 4 Taking the spray tank 201 and the auxiliary tank 211 as an example, the auxiliary tank 211 is located lower than the spray tank 201, and the upper part of the auxiliary tank 211 is connected to the lower part of the spray tank 201, so that the water in the spray tank 201 can flow into the auxiliary tank 211.

[0059] Each of the auxiliary tanks is connected to the auxiliary tanks of the adjacent spray tanks. In this embodiment, different connection methods are used according to the contamination of water in each auxiliary tank after cleaning. Since the water in the auxiliary tanks of the rear three spray tanks (i.e., auxiliary tanks 213, 214, and 215) is less contaminated, a method of directly connecting the upper part of the rear three auxiliary tanks is adopted. The water in the auxiliary tanks of the first two spray tanks (i.e., auxiliary tanks 211 and 212) is more contaminated, so the auxiliary tanks 213 (i.e., the auxiliary tank of the third spray tank) and the auxiliary tank 212 (i.e., the auxiliary tank of the second spray tank) are connected by overflow, and the auxiliary tanks 212 and the auxiliary tanks 211 are connected to avoid the backflow of contamination.

[0060] For details, please refer to Figure 5 In this embodiment, the auxiliary groove 213, the auxiliary groove 214 and the auxiliary groove 215 are separated by two partitions 217 in the same long groove 216, and a gap is left between the upper ends of the two partitions 217 and the top wall of the long groove 216, so that the upper parts of the auxiliary grooves 213, 214 and 215 are connected. Through the above structure, the layout of the connecting structure between the auxiliary grooves 213, 214 and 215 can be simplified. The upper part of the auxiliary groove 212 is connected to the lower part of the auxiliary groove 211 through the first connecting pipe 221, and the upper part of the auxiliary groove 213 is connected to the lower part of the auxiliary groove 212 through the second connecting pipe 222.

[0061] A drain pipe 223 is provided at the upper part of the auxiliary tank 211, and the drain pipe 223 is generally connected to the sewage tank 400, and is used to discharge the sewage at the upper part of the auxiliary tank 211 to the sewage tank 400. The auxiliary tank 215 (i.e., the auxiliary tank of the fifth-stage spray tank) is connected to the second water supply unit for receiving clean water. Since dirt such as oil generally floats on the water surface, after the auxiliary tank 215 is connected to clean water, the dirt floating on the upper part will flow into the auxiliary tank 214 along the direction of the water flow, thereby replacing part of the dirty water with clean water, so that the water in the auxiliary tank 215 maintains a high degree of cleanliness. Similarly, the dirt floating on the upper part of the auxiliary tank 214 will flow into the auxiliary tank 213 along the direction of the water flow, and the water in the auxiliary tank 215 will replace part of the original water in the auxiliary tank 214. Afterwards, the water in the auxiliary tank 213 will also flow to the auxiliary tank 212, and the water in the auxiliary tank 212 will also flow to the auxiliary tank 211, and the water in the auxiliary tank 211 will be directly discharged into the sewage pool 400. Since the auxiliary tanks 213 and 212, and the auxiliary tanks 212 and 211 are connected to other auxiliary tanks by connecting pipes, the backflow of the sewage in the auxiliary tanks can be avoided.

[0062] Please continue reading Figure 1The second water supply unit includes a second water supply pipe 320 connecting the water source 300 and the auxiliary tank 215 (i.e., the auxiliary tank of the last stage of the spray tank), and a second flow meter 321 and a proportional valve 322 arranged in series on the second water supply pipe 320; so as to count the water intake of the second cleaning unit through the second flow meter 321, and control the water supply rate to the second cleaning unit through the proportional valve 322.

[0063] Please continue reading Figure 3 The second detection control unit includes a second control module 520 and conductivity sensors correspondingly arranged in each sub-tank (i.e., a conductivity sensor 521 installed in the sub-tank 211, a conductivity sensor 522 installed in the sub-tank 212, a conductivity sensor 523 installed in the sub-tank 213, a conductivity sensor 524 installed in the sub-tank 214, and a conductivity sensor 525 installed in the sub-tank 215). The second control module 520 detects the conductivity of water in the sub-tank 211 through the conductivity sensor 521, detects the conductivity of water in the sub-tank 212 through the conductivity sensor 522, detects the conductivity of water in the sub-tank 213 through the conductivity sensor 523, detects the conductivity of water in the sub-tank 214 through the conductivity sensor 524, and detects the conductivity of water in the sub-tank 215 through the conductivity sensor 525. The opening of the proportional valve 322 is controlled according to the detection results of the conductivity sensor 521, the conductivity sensor 522, the conductivity sensor 523, the conductivity sensor 524 and the conductivity sensor 525, thereby controlling the water supply rate of the second water supply unit so that the conductivity of the water in the auxiliary tank 215 remains lower than the preset value.

[0064] In order to enable the second control module 520 to accurately control and adjust the water supply of the second water supply unit according to the conductivity of the water in the five auxiliary tanks, and to maximize water saving; in this embodiment, the second control module 520 adopts a cloud control system, and a first cleaning control model, a second cleaning control model and a third cleaning control model are set in the second control module 520. The first cleaning control model is used to control the opening of the proportional valve 322 according to the detection results of each conductivity sensor when the single-piece cleaning water volume of the product is higher than the first water volume threshold a1, so that the single-piece cleaning water volume drops to below the first water volume threshold a1, and the conductivity of the water in the auxiliary tank of the last stage of the spray tank is kept below the preset value.

[0065] The second cleaning control model is used to control the opening of the proportional valve 322 according to the detection results of each conductivity sensor when the single-piece cleaning water volume of the product is lower than the first water volume threshold a1 and higher than the second water volume threshold a2, so that the single-piece cleaning water volume is maintained between the first water volume threshold a1 and the second water volume threshold a2, and the conductivity of the water in the sub-tank of the last-stage spray tank is kept lower than the preset value.

[0066] The third cleaning control model is used to control the opening of the proportional valve 322 according to the detection results of each conductivity sensor when the single-piece cleaning water volume of the product is lower than the second water volume threshold a2, so that the single-piece cleaning water volume increases to be higher than the second water volume threshold a2, and the conductivity of the water in the sub-tank of the last-stage spray tank is kept lower than the preset value.

[0067] The first cleaning control model, the second cleaning control model and the third cleaning control model are all obtained after big data collection, analysis and cleaning of the working data of the cleaning line, forming corresponding training sets and verification sets for training the deep learning model. In this embodiment, the first cleaning control model, the second cleaning control model and the third cleaning control model all adopt the random forest model to facilitate the comprehensive measurement results of the five conductivity sensors to obtain a nearly optimal opening value of the proportional valve 322.

[0068] See also Figure 6 The cleaning control process of the second control module 520 includes the following steps:

[0069] SA1. Detect the water level in the auxiliary tank 211 through the liquid level sensor 526. If the water level in the auxiliary tank 211 is higher than the preset value, it means that the water in the auxiliary tank meets the cleaning requirements, and execute step S101 to start cleaning the product. Otherwise, it means that there is too little water in the auxiliary tank, and execute step SA2 to add water to the auxiliary tank.

[0070] SA2, adjust the opening of the proportional valve 322 to the maximum value, so that the water level of the auxiliary tank is higher than the preset value, and then execute step S101. Of course, if the liquid level sensor 526 is not provided in the auxiliary tank 211, step SA1 can be omitted and step SA2 can be entered, and step S101 can be directly executed.

[0071] S101, since the second cleaning control model is the control model used under normal circumstances, this step first selects the second cleaning control model as the current control model. Of course, the first cleaning control model or the third cleaning control model can also be selected as the current control model. Under normal circumstances, after a period of execution, the second cleaning control model will still be used as the current control model.

[0072] S102, the current control model detects the conductivity once every first preset time. If the first preset time is too long, it will cause untimely adjustment and affect the cleaning effect of the product. If it is too short, it will increase the amount of system calculation and increase the cost. Therefore, the value of the first preset time can be determined according to the actual test situation. In this embodiment, the first preset time is set to 5S, that is, the conductivity of the water in the five auxiliary tanks is collected every 5 seconds.

[0073] In order to avoid special circumstances (for example, the lower limit of the concentration value range of the reagent is set too low, resulting in too low concentration of the reagent in the reagent tank 101, so that the product has too much oil and other dirt left after cleaning in the reagent tank 101, and cannot be cleaned in the subsequent process), the current control model cannot keep the conductivity of the water in the auxiliary tank (i.e., the auxiliary tank 215) of the last-stage spray tank below the preset value, this step can also determine whether the conductivity of the water in the auxiliary tank 215 is lower than the preset value after each conductivity detection. If it is lower than the preset value, it means that the cleaning is normal, and then execute step S103. Otherwise, execute step S107 to carry out the special situation processing flow.

[0074] S103, the current control model outputs the predicted value of the opening of the proportional valve 322 according to the conductivity detection result, and controls the opening of the proportional valve 322. Since the deep learning model is used in this embodiment to comprehensively control the conductivity of the water in the five auxiliary tanks, the predicted value of the opening of the proportional valve 322 is very close to the optimal value, so that water saving can be maximized under the current capacity.

[0075] S104, the current control model calculates the single-piece washing water volume a0 of the product once every second preset time according to the measured value of the second flow meter 321 and the number of products to be washed. In this embodiment, the second preset time is taken as 2 hours, that is, the single-piece washing water volume of the product is calculated once every 2 hours. The calculation method is to first obtain the water consumption for 2 hours according to the second flow meter 321, and then divide the 2-hour water consumption by the number of products to be washed within 2 hours. At this time, it is necessary to set a larger first water volume threshold a1 (for example: a1 can be set to 1.5L) and a smaller second water volume threshold a2 (for example: a2 can be set to 0.8L). Of course, the above values ​​are determined according to the specific product situation in this embodiment. When washing other products, the first water volume threshold a1 and the second water volume threshold a2 need to be determined according to the actual situation of the product. If the single-piece washing water volume a0 is higher than the first water volume threshold a1, it means that the current control model uses too much water, and the control model needs to be switched for adjustment, and step S106 is executed. If the single-chip washing water volume a0 is lower than the second water volume threshold a2, it means that the current control model uses too little water, and there may be a problem of incomplete washing, and the control model needs to be switched for adjustment, and step S105 is executed at this time. If the single-chip washing water volume of the product is between the first water volume threshold a1 and the second water volume threshold a2, it means that the current control model is washing normally, and there is no need to adjust the control model, and the process returns to step S101.

[0076] S105, select the third cleaning control model as the current control model, and return to execute step S102.

[0077] S106, selecting the first cleaning control model as the current control model, and returning to execute step S102.

[0078] S107, forcibly adjusting the opening of the proportional valve 322 to the maximum value, and maintaining the third preset time. The third preset time can be set as needed. In this embodiment, the third preset time is set to 5 minutes.

[0079] S108, detect the conductivity of the water in the auxiliary tank of the last stage of the spray tank, if it is lower than the preset value, exit the special situation processing flow and return to step S101. Otherwise, it means that the product cannot be cleaned by controlling the water intake of the second water supply unit. At this time, it is generally caused by the low concentration of the agent in the agent tank 101. Therefore, step S109 is executed to force the addition of agents to the agent tank 101 to increase the agent concentration (after the increase, it will still be within the preset agent concentration range).

[0080] S109 , enabling the first control unit 510 to control the drug adding motor 112 to operate, so as to add drugs into the mixing tank 102 , so as to increase the concentration of the drugs in the drug tank 101 .

[0081] Of course, during the control process of the second control module 520, the first control module 510 will also control the concentration of the reagent in the reagent tank 101 by adding reagents and water according to the detection result of the reagent concentration, so that the concentration of the reagent in the reagent tank 101 is always protected within the preset range. Except for executing step S109, the control process of the reagent concentration by the first control module 510 and the cleaning control process of the second control module 520 are basically independent of each other.

[0082] After adopting the structure and control method of this embodiment, after 72 hours of testing, it was found that the improved technical solution of this embodiment was used, and the single-chip washing water volume was only about 0.82L, which was more than half of the 1.86L single-chip washing water volume before the improvement, achieving a good water-saving effect. In addition, the conductivity of the water in each sub-slot is more stable after the improvement. The two indicators of conductivity stability are evaluated as shown in Table 1, which is the conductivity detection data of the water in each sub-slot after the improved technical solution of this embodiment and before the improvement. The standard deviation of the conductivity of the water in the four sub-slots after this embodiment is significantly smaller than before the improvement, especially the last sub-slot, whose standard deviation of conductivity is very small. It can be seen that the technical solution of this embodiment not only has a good water-saving effect, but also the conductivity of the water in the latter sub-slot is more stable, making the cleaning effect of the product more stable.

[0085] In this embodiment, the first control module 510 is used to realize automatic control of the concentration of the reagent, and the second control module 520 can automatically control the opening of the proportional valve 322 according to the product cleaning situation, and the second control module 520 uses three deep learning models to control the three situations respectively, so that the predicted value of the opening of the proportional valve 322 can be very close to the optimal value of the opening value of the proportional valve 322, so that water saving can be achieved to the extreme and the purpose of intelligent water control can be achieved. Moreover, the conductivity of the water in each auxiliary tank is more stable, so that the cleaning effect of the product is also more stable. In addition, this embodiment is also provided with a special situation processing flow, which can force the water intake to increase or add reagents in the special case that the conductivity of the water in the auxiliary tank of the last stage spray tank exceeds the preset value, so as to ensure that the cleanliness of the product after cleaning meets the requirements.
