[0024] See also Figure 1, which is a flow chart of a method for cleaning a circuit board horizontal line production tool according to an embodiment of the present invention. The method for cleaning a circuit board horizontal line production tool includes part or all of the following steps.

[0025] S100: placing the production tools to be cleaned on the cleaning support.

[0026] In this embodiment, the production tool to be cleaned is a component on the horizontal production line of printed circuit boards, that is, the production tool to be cleaned is part of the production components of the horizontal production line of printed circuit boards, that is, the production tool to be cleaned is a component removed from the horizontal production line of printed circuit boards. Specifically, the production tool to be cleaned includes at least one of a roller, a water knife and a nozzle. Before the production tool to be cleaned is maintained and cleaned, the production tool to be cleaned is first placed on the cleaning bracket, that is, the production tool to be cleaned is placed on the cleaning bracket on the cleaning table. The cleaning bracket is a hollow structure. The cleaning bracket corresponds to the first cleaning tank and the second cleaning tank, so that after the production tool to be cleaned is cleaned, the foreign matter blocked in the production tool to be cleaned is flushed into the corresponding cleaning tank. Among them, for the cleaning of the production tool to be cleaned, the cleaning liquid passes through the output channel of the production tool to be cleaned, that is, with the help of its working channel, so as to clean the main attachment area of ​​the foreign matter.

[0027] S200: cleaning the production tool to be cleaned of foreign objects, so as to remove the foreign objects blocking the production tool to be cleaned.

[0028] In this embodiment, the production tools to be cleaned are placed on the cleaning bracket, and the cleaning nozzle is used to clean the production tools to be cleaned, wherein one end of the cleaning nozzle is connected to the cleaning liquid supply device, and the other end of the cleaning nozzle is connected to the internal channel of the production tools to be cleaned. Specifically, the cleaning nozzle guides tap water to the internal channel of the production tools to be cleaned, so as to flush and clean the internal channel of the production tools to be cleaned, so as to remove the clogging foreign matter attached to the production tools to be cleaned, thereby facilitating the filling of the clogging foreign matter attached to the production tools to be cleaned into the corresponding cleaning tank, and further facilitating the subsequent separate discharge treatment of clogging foreign matter of different chemical properties.

[0029] S300: adjusting the opening and closing states of the acid-base drain valve according to the production state parameters of the production tools to be cleaned.

[0030] In this embodiment, the production status parameter is a parameter corresponding to the current production situation of the production tool to be cleaned, that is, the production status parameter reflects the usage status of the production tool to be cleaned on the horizontal production line of the printed circuit board, that is, the production status parameter corresponds to the current production environment of the production tool to be cleaned. Specifically, the production status parameter is a parameter corresponding to the pH environment of the production tool to be cleaned on the horizontal production line of the printed circuit board, which is convenient for determining the acidity and alkalinity of the foreign matter blocking the production tool to be cleaned, and thus it is convenient to determine the opening and closing status of the acid-base drain valve according to the acidity and alkalinity of the blocked foreign matter cleaned, and then it is convenient to treat wastewater with different acidity and alkalinity separately, which effectively improves the recovery and treatment efficiency of the cleaning wastewater, and also reduces the difficulty of treating the cleaning wastewater.

[0031] In the above embodiment, the production tools to be cleaned are placed on the cleaning bracket to facilitate the cleaning of the production tools to be cleaned, thereby facilitating the flushing of foreign matter attached to the production tools to be cleaned into the corresponding cleaning tank, so that foreign matter of different chemical properties on the production tools to be cleaned can be accommodated separately, and then different drain valves can be opened to discharge foreign matter of different chemical properties, which effectively facilitates the acid-base classification treatment of foreign matter on the production tools to be cleaned, thereby effectively reducing the difficulty of subsequent wastewater treatment, and thereby improving the cleaning efficiency of the circuit board horizontal line production tools.

[0032] In one embodiment, the cleaning bracket includes an acid cleaning bracket and an alkaline cleaning bracket, the opening of the first cleaning tank faces the acid cleaning bracket, and the opening of the second cleaning tank faces the alkaline cleaning bracket. In this embodiment, the cleaning bracket is used to place the production tools to be cleaned, and the production tools to be cleaned have blocking foreign bodies of different chemical properties under different use environments. Specifically, in different production sections or production stations of the printed circuit board horizontal production line, the production agents used for the printed circuit board are different, so that the chemical properties of the blocking foreign bodies attached to the production tools to be cleaned are different, that is, the acidity and alkalinity of the blocking foreign bodies are different. In this way, after the production tools to be cleaned on different production sections or production stations are disassembled, the acidity and alkalinity of the blocking foreign bodies on the production tools to be cleaned can be determined according to the acidity and alkalinity of the production agents used, so as to facilitate the placement of the production tools to be cleaned on the corresponding cleaning bracket, and then facilitate the cleaning of the blocking foreign bodies with different acidity and alkalinity into the corresponding cleaning tank, so as to achieve the separate cleaning of the blocking foreign bodies on the production tools to be cleaned.

[0033] Furthermore, placing the production tools to be cleaned on the cleaning bracket includes: placing the production tools to be cleaned on a corresponding one of an acid cleaning rack and an alkaline cleaning rack. In this embodiment, the cleaning bracket is used to place the production tools to be cleaned, and the production tools to be cleaned have blocking foreign bodies of different chemical properties under different use environments. Specifically, in different production sections or production stations of the horizontal production line of printed circuit boards, different production agents are used for printed circuit boards, so that the chemical properties of the blocking foreign bodies attached to the production tools to be cleaned are different, that is, the acidity and alkalinity of the blocking foreign bodies are different. In this way, after the production utensils to be cleaned are placed on different cleaning racks, the cleaning nozzles clean the production utensils to be cleaned, so that the clogging foreign matter on the production utensils to be cleaned can be flushed into the corresponding cleaning tanks. Specifically, when the clogging foreign matter on the production utensils to be cleaned is acidic, the production utensils to be cleaned are placed on the acidic cleaning rack, and the first cleaning tank collects the acidic clogging foreign matter on the production utensils to be cleaned; and when the clogging foreign matter on the production utensils to be cleaned is alkaline, the production utensils to be cleaned are placed on the alkaline cleaning rack, and the second cleaning tank collects the alkaline clogging foreign matter on the production utensils to be cleaned, so that the clogging foreign matter of different acidity and alkalinity on the production utensils to be cleaned can be cleaned and collected separately, thereby facilitating the separate recycling of wastewater containing clogging foreign matter.

[0034] In one embodiment, the cleaning nozzle is connected to the central channel of the production tool to be cleaned to flush out foreign matter in the central channel. In this embodiment, the cleaning nozzle is used to guide the cleaning liquid to the production tool to be cleaned, so as to facilitate the injection of the cleaning liquid into the central channel of the production tool to be cleaned, thereby facilitating the cleaning of the central channel of the production tool to be cleaned, and further facilitating the removal of the main blocking foreign matter in the production tool to be cleaned, so as to improve the cleaning efficiency of the production tool to be cleaned. The central channel is an area in the production tool to be cleaned that is more prone to foreign matter attachment. For example, the production tool to be cleaned is a roller, and the central channel is the central axis of the roller; for another example, the production tool to be cleaned is a nozzle, and the central channel is the nozzle outlet of the nozzle; for another example, the production tool to be cleaned is a water jet, and the central channel is the water outlet line groove of the water jet.

[0035] Furthermore, the cleaning assembly further includes a pressure-boosting component, which is connected to the cleaning nozzle and is used to increase the pressure inside the cleaning nozzle. In this embodiment, the pressure-boosting component is a pressure-boosting air gun, which pressurizes the cleaning liquid provided by the cleaning nozzle, so that the pressure of the cleaning liquid sprayed out by the pressure-boosting air gun increases, thereby increasing the cleaning pressure of the production tools to be cleaned, and further increasing the cleaning intensity of the production tools to be cleaned, so as to facilitate cleaning the blocking foreign matter on the production tools to be cleaned as much as possible, and also improve the cleaning efficiency of the production tools to be cleaned.

[0036] Furthermore, the cleaning assembly further includes a hose connected to the booster, and the hose is also connected to the cleaning nozzle. In this embodiment, the hose serves as a connecting component between the booster and the cleaning nozzle. The hose is flexible, so as to facilitate adjustment of the cleaning angle of the booster to the production tool to be cleaned, and further clean the blocking foreign matter on the production tool to be cleaned as much as possible, thereby further improving the cleaning efficiency of the production tool to be cleaned.

[0037] In one embodiment, the cleaning of the production tool to be cleaned to remove the blocked foreign matter on the production tool to be cleaned includes: connecting the nozzle of the cleaning nozzle to the central channel of the production tool to be cleaned; and injecting cleaning liquid into the central channel. In this embodiment, the central channel of the production tool to be cleaned serves as the attachment area of ​​the blocked foreign matter, and connecting the nozzle of the cleaning nozzle to the central channel of the production tool to be cleaned facilitates the introduction of the cleaning liquid in the cleaning nozzle into the central channel of the production tool to be cleaned, thereby facilitating the flushing of the blocked foreign matter in the central channel, so that the blocked foreign matter on the production tool to be cleaned can be cleaned as soon as possible.

[0038] In one embodiment, the adjusting the opening and closing state of the acid-base drain valve according to the production state parameter of the production tool to be cleaned includes: detecting whether the production state parameter is greater than a preset state parameter; when the production state parameter is greater than the preset state parameter, closing the acid drain valve and opening the alkaline drain valve. In this embodiment, the production state parameter is a parameter corresponding to the current production situation of the production tool to be cleaned, that is, the production state parameter reflects the use state of the production tool to be cleaned on the horizontal production line of the printed circuit board, that is, the production state parameter corresponds to the current production environment of the production tool to be cleaned, specifically, the production state parameter is a parameter corresponding to the use acid-base environment of the production tool to be cleaned on the horizontal production line of the printed circuit board. The preset state parameter is a reference acid-base parameter of the foreign matter blocking the production tool to be cleaned, for example, the preset state parameter is the central acid-base, and the preset state parameter is a pH value between 6.8 and 7.3. The production state parameter is greater than the preset state parameter, indicating that the pH value of the blocking foreign matter on the production tool to be cleaned exceeds the reference pH value, that is, indicating that the blocking foreign matter on the production tool to be cleaned is alkaline blocking foreign matter, and at this time, the wastewater flushed into the cleaning tank by the cleaning nozzle is alkaline wastewater, and by only opening the alkaline drain valve, the alkaline blocking foreign matter can be discharged into the alkaline wastewater recovery tank, so as to be recovered separately from the acidic blocking foreign matter. Wherein, the alkaline wastewater recovery tank is connected to the alkaline drain valve.

[0039] Furthermore, the detection of whether the production status parameter is greater than the preset status parameter further includes: when the production status parameter is less than the preset status parameter, the acidic drain valve is opened and the alkaline drain valve is closed. In this embodiment, the production status parameter is a parameter corresponding to the current production situation of the production tool to be cleaned, that is, the production status parameter reflects the use status of the production tool to be cleaned on the horizontal production line of the printed circuit board, that is, the production status parameter corresponds to the current production environment of the production tool to be cleaned. Specifically, the production status parameter is a parameter corresponding to the use pH environment of the production tool to be cleaned on the horizontal production line of the printed circuit board. The preset status parameter is a reference acid-base parameter of the foreign matter blocking the production tool to be cleaned. For example, the preset status parameter is the central pH, and the preset status parameter is a pH value between 6.8 and 7.3. The production state parameter is less than the preset state parameter, indicating that the pH value of the blocking foreign matter on the production tool to be cleaned is lower than the reference pH value, that is, indicating that the blocking foreign matter on the production tool to be cleaned is acidic blocking foreign matter, and the wastewater flushed into the cleaning tank by the cleaning nozzle is acidic wastewater. By only opening the acidic drainage valve, the acidic blocking foreign matter can be discharged into the acidic wastewater recovery tank, so as to be recovered separately from the alkaline blocking foreign matter. The acidic wastewater recovery tank is connected to the acidic drainage valve.

[0040] Furthermore, the detection of whether the production status parameter is greater than the preset status parameter further includes: when the production status parameter is equal to the preset status parameter, opening at least one of the acidic drain valve and the alkaline drain valve. In this embodiment, the production status parameter is a parameter corresponding to the current production situation of the production tool to be cleaned, that is, the production status parameter reflects the use status of the production tool to be cleaned on the horizontal production line of the printed circuit board, that is, the production status parameter corresponds to the current production environment of the production tool to be cleaned, specifically, the production status parameter is a parameter corresponding to the use pH environment of the production tool to be cleaned on the horizontal production line of the printed circuit board. The preset status parameter is a reference acid-base parameter of the foreign matter blocking the production tool to be cleaned, for example, the preset status parameter is the central pH, and the preset status parameter is a pH value between 6.8 and 7.3. The production status parameter is equal to the preset status parameter, indicating that the pH value of the clogging foreign matter on the production tool to be cleaned is equal to the reference pH value, that is, the clogging foreign matter on the production tool to be cleaned is a neutral clogging foreign matter. At this time, the wastewater flushed into the cleaning tank by the cleaning nozzle is neutral wastewater. By opening any one of the acid drain valve and the alkaline drain valve, or opening both of them, the neutral clogging foreign matter can be discharged into the wastewater recovery tank.

[0041] It is understandable that most of the production tools to be cleaned are of relatively high precision, especially the water jets with long strip water outlet grooves. Since such water jets are basically used in small areas or small diameter spaces, when slight deformation occurs, the water jet cross-section sprayed by the water jet becomes abnormal and cannot be used. In the case where the blocking foreign matter has been deposited for a long time, hardening is prone to occur, that is, the hardness of the crystals formed by the blocking foreign matter is too high, resulting in the cleaning nozzle being unable to remove such blocking foreign matter. In addition, in order to avoid deformation of the water jet, the spray pressure of the cleaning nozzle will not be very high, which makes the cleaning of the water jet more difficult.

[0042] In order to reduce the difficulty of cleaning the production tools to be cleaned, especially the difficulty of cleaning the water jet with a long strip water outlet groove, the opening and closing states of the acid-base drain valve are adjusted according to the production state parameters of the production tools to be cleaned, and the following steps are also included:

[0043] After a first preset cleaning time, obtaining a water curtain image of the production tool to be cleaned;

[0044] Acquire the water outlet area according to the water outlet curtain image;

[0045] Performing area normalization processing on the water outlet area and the preset area to obtain an area normalization ratio;

[0046] Detecting whether the face return ratio is equal to 1;

[0047] When the face-to-face ratio is equal to 1, step S300 is executed.

[0048] In this embodiment, the water outlet curtain image is a water outlet image collected after pre-cleaning the production tool to be cleaned, that is, the water outlet curtain image is an image formed by the liquid sprayed out of the output end of the production tool to be cleaned after a certain cleaning time, that is, after preliminary cleaning, the water outlet condition of the production tool to be cleaned is determined. Among them, the water outlet curtain image is used to reflect the water outlet image of the production tool to be cleaned after a certain cleaning time. At this time, if there is no hardened clogging foreign matter, the water outlet curtain image will be complete. By collecting the water outlet area of ​​the water outlet curtain image, it is convenient to determine the water outlet condition of the production tool to be cleaned after pre-cleaning, that is, to determine whether there are still clogging foreign matter in the production tool to be cleaned. The surface normalization of the water outlet area and the preset area is a comparison of the current water outlet situation of the production tool to be cleaned with the standard water outlet situation, that is, comparing the current water outlet curtain image of the production tool to be cleaned with the standard water outlet curtain image, and normalizing the water outlet area between the above, and the obtained surface normalization ratio is the ratio between the current water outlet area of ​​the production tool to be cleaned and the standard water outlet area, so as to facilitate the determination of the current water outlet difference degree of the production tool to be cleaned. The surface normalization ratio is equal to 1, indicating that the current water outlet situation of the production tool to be cleaned is normal, that is, it indicates that the water outlet curtain of the production tool to be cleaned is complete, that is, it indicates that the blocking foreign matter in the production tool to be cleaned has been completely removed, and the subsequent drainage steps can be continued at this time.

[0049] Further, it is detected whether the face return ratio is equal to 1, and then it also includes:

[0050] When the surface-to-surface ratio is less than 1, ultrasonic cleaning is performed on the production tool to be cleaned within a second preset cleaning time;

[0051] Return to step S200.

[0052] In this embodiment, the water outlet curtain image is a water outlet image collected after pre-cleaning the production tool to be cleaned, that is, the water outlet curtain image is an image formed by the liquid sprayed out of the output end of the production tool to be cleaned after a certain cleaning time, that is, after preliminary cleaning, the water outlet condition of the production tool to be cleaned is determined. Among them, the water outlet curtain image is used to reflect the water outlet image of the production tool to be cleaned after a certain cleaning time. At this time, if there is no hardened clogging foreign matter, the water outlet curtain image will be complete. By collecting the water outlet area of ​​the water outlet curtain image, it is convenient to determine the water outlet condition of the production tool to be cleaned after pre-cleaning, that is, to determine whether there are still clogging foreign matter in the production tool to be cleaned. The surface normalization of the water outlet area and the preset area is a comparison of the current water outlet situation of the production tool to be cleaned with the standard water outlet situation, that is, comparing the current water outlet curtain image of the production tool to be cleaned with the standard water outlet curtain image, and normalizing the water outlet area between the above, and the obtained surface normalization ratio is the ratio between the current water outlet area of ​​the production tool to be cleaned and the standard water outlet area, so as to facilitate the determination of the current water outlet difference degree of the production tool to be cleaned. The surface normalization ratio is less than 1, indicating that the current water outlet area of ​​the production tool to be cleaned is reduced, that is, it indicates that the water outlet curtain of the production tool to be cleaned is incomplete, that is, it indicates that there are hardened blocking foreign bodies in the production tool to be cleaned. In this way, the production tool to be cleaned is placed on an ultrasonic cleaner at this time, so as to facilitate ultrasonic cleaning of the production tool to be cleaned, so that the hardened blocking foreign bodies in the production tool to be cleaned are loosened and fall off, so that the production tool to be cleaned is cleaned again, and then the blocking foreign bodies on the production tool to be cleaned are further completely cleaned. Wherein, the first preset cleaning time and the second preset cleaning time can be determined according to actual conditions.

[0053] In another embodiment, the cleaning component further includes an ultrasonic cleaner, which is disposed in the cleaning table and is used to place the production tools to be cleaned during ultrasonic cleaning. In this way, when ultrasonic treatment is required for the hardened and blocked foreign matter in the production tools to be cleaned, the production tools to be cleaned are placed on the ultrasonic cleaner, and the hardened and blocked foreign matter in the production tools to be cleaned is vibrated and loosened by the ultrasonic resonance of the ultrasonic cleaner, thereby improving the cleaning efficiency of the production tools to be cleaned, and further improving the cleanliness of the production tools to be cleaned.

[0054] In one embodiment, the present application also provides a production tool cleaning device, which includes a cleaning component and a drainage component; the cleaning component includes a cleaning bracket, a cleaning table and a cleaning nozzle, the cleaning table is provided with a first cleaning tank and a second cleaning tank, the cleaning bracket corresponds to the first cleaning tank and the second cleaning tank, the cleaning bracket is used to place the production tools to be cleaned, the cleaning nozzle is used to clean the production tools to be cleaned, the first cleaning tank is used to accommodate acidic clogging foreign matter, and the second cleaning tank is used to accommodate alkaline clogging foreign matter; the drainage component includes an acidic drainage valve and an alkaline drainage valve, the acidic drainage valve is connected to the first cleaning tank for discharging acidic clogging foreign matter, and the alkaline drainage valve is connected to the second cleaning tank for discharging alkaline clogging foreign matter. In this embodiment, the production tools to be cleaned are placed on a cleaning bracket to facilitate the cleaning of the production tools to be cleaned, thereby facilitating the flushing of foreign matter attached to the production tools to be cleaned into the corresponding cleaning tank, so that foreign matter of different chemical properties on the production tools to be cleaned can be accommodated separately, thereby facilitating the opening of different drain valves to achieve the discharge of foreign matter of different chemical properties, and effectively facilitating the acid-base classification treatment of foreign matter on the production tools to be cleaned, thereby effectively reducing the difficulty of subsequent wastewater treatment, and thereby improving the cleaning efficiency of the circuit board horizontal line production tools.
