[0029] See Figure 1 , Figure 1 1 is a flow chart of a method for cleaning a negative pressure forming cup 6 provided by an embodiment of the present invention. A method for cleaning a negative pressure forming cup provided by an embodiment of the present invention comprises the following steps:

[0030] Step S1, close the solenoid valve 3, inject the first cleaning agent in the liquid storage tank 1 into the negative pressure cup 6 through the infusion pipe 2 until it is full, and completely immerse the negative pressure cup 6 in the first cleaning agent according to a first static soaking time;

[0031] As an embodiment, closing the solenoid valve 3 and injecting the first cleaning agent in the liquid storage tank 1 into the negative pressure cup 6 from the infusion pipe 2 until it is full includes closing the solenoid valve 3, loading the first cleaning agent into the liquid storage tank 1, and then injecting the first cleaning agent from the liquid storage tank 1 through the first infusion pipe 2 into the negative pressure cup 6 until it is full.

[0032] As an embodiment, the first static soaking time is greater than or equal to 5 minutes.

[0033] Specifically, the liquid storage tank 1 is in fluid communication with the negative pressure cup 6 via an infusion pipe 2. The infusion pipe 2 is provided with a solenoid valve 3 for controlling the flow of liquid. The interior of the liquid storage tank 1 has a storage chamber for containing a first cleaning agent. The control panel 5 described below includes an operation panel integrated with a control processor. During implementation, an operation instruction is sent from the operation panel to the control processor, which in turn sends a closing signal to the solenoid valve 3. After the solenoid valve 3 is closed, the first cleaning agent in the liquid storage tank 1 flows through the infusion pipe 2 under the action of gravity or pumping and eventually completely fills the negative pressure cup 6. If the first cleaning agent is loaded into the liquid storage tank 1, the first cleaning agent can be injected into the negative pressure cup 6 from the liquid storage tank 1 through the infusion pipe 2. After closing the solenoid valve 3, the first cleaning agent in the liquid storage tank 1 will flow through the infusion pipe 2 and into the negative pressure cup 6 until it is full. In addition, the liquid level can be detected by a liquid level sensor provided on the negative pressure cup 6 or the infusion pipe 2, so that a signal is sent when the liquid is full. After the negative pressure cup 6 is filled with the first cleaning agent, an operating instruction is issued from the operation panel to the control processor, which in turn issues an instruction to close the solenoid valve 3 on the infusion pipe 2, cutting off the liquid passage between the liquid storage tank 1 and the negative pressure cup 6, so that the negative pressure cup 6 remains filled. At this point, the negative pressure cup 6 is completely enveloped by the first cleaning agent, and the control processor starts a timer that continues counting until the preset first static soaking time. If the time reaches 5 minutes, the next step S2 is triggered, allowing the first cleaning agent and the dirt on the inner surface of the negative pressure cup 6, namely the water-soluble and partially heat-soluble dirt, sufficient time to undergo thermal dissolution, diffusion, and chemical reactions, which helps the contaminants escape from the inner wall of the negative pressure cup 6.

[0034] Step S2: opening the solenoid valve 3 and using a negative pressure suction unit to suck the first cleaning agent in the negative pressure cup 6 and the infusion pipe 2, wherein the first cleaning agent includes hot water;

[0035] As an embodiment, the temperature of the hot water ranges from 80°C to 100°C.

[0036] As an embodiment, the using a negative pressure suction unit to suck the first cleaning agent from the negative pressure cup 6 and the infusion pipe 2 includes using a negative pressure suction unit at -80KPa to -90KPa to suck the first cleaning agent from the negative pressure cup 6 and the infusion pipe 2;

[0037] Specifically, after the immersion time in step S2 has expired and a completion signal has been received, a command can be issued to open solenoid valve 3 on infusion pipe 2, thereby connecting negative pressure cup 6 with infusion pipe 2. Simultaneously, a negative pressure suction unit, such as a vacuum pump, is activated to forcefully draw the first cleaning agent liquid and any dissolved and suspended dirt from the interior of negative pressure cup 6 and infusion pipe 2 at a pressure of -80 kPa to -90 kPa through infusion pipe 2. This directional fluid movement from negative pressure cup 6 through infusion pipe 2 to the exterior utilizes the force generated by the strong negative pressure to remove any remaining contaminants adhering to the cup wall and the inner wall of the pipe, even if some have been loosened during immersion but have not yet detached from the surface. The liquid containing the dirt is then discharged, reducing residual dead spots.

[0038] Step S3, starting the positive pressure purge unit to purge the infusion pipe 2 and the negative pressure cup 6;

[0039] Specifically, after the suction operation in step S2 is completed and the negative pressure suction unit is turned off, the positive pressure purge unit, such as an air compressor or an inert gas source, can be started. The positive pressure purge unit outputs gas, such as clean air or nitrogen, which is blown into the infusion pipe 2 at high speed and flows through the interior of the infusion pipe 2 and the inner cavity of the negative pressure cup 6. That is, by introducing the impact force and shear force generated by the high-speed airflow, any liquid film or tiny droplets remaining on the inner wall of the infusion pipe 2 and the inner wall of the negative pressure cup 6 are acted on, broken up, peeled off and blown to the outside of the negative pressure cup 6. The high-speed flow of gas is conducive to drying residual moisture and removing tiny particles remaining in the infusion pipe 2 and the negative pressure cup 6.

[0040] Step S4: close the solenoid valve 3, inject the second cleaning agent in the liquid storage tank 1 into the negative pressure cup 6 through the infusion pipe 2 until it is full, and completely immerse the negative pressure cup 6 in the second cleaning agent according to the second static soaking time;

[0041] As an embodiment, before step S4, the method further includes cyclically executing steps S1 to S3 according to a preset first cycle number; wherein the first cycle number is at least 1;

[0042] As an embodiment, closing the solenoid valve 3 and injecting the second cleaning agent in the liquid storage tank 1 from the infusion pipe 2 into the negative pressure cup 6 until it is full includes closing the solenoid valve 3, clearing the first cleaning agent sucked into the liquid storage tank 1, and then loading the second cleaning agent into the liquid storage tank 1, and injecting the second cleaning agent in the liquid storage tank 1 from the infusion pipe 2 into the negative pressure cup 6 until it is full.

[0043] As an embodiment, the second static soaking time is greater than or equal to 5 minutes.

[0044] Specifically, if the number of cycles set for the first cycle is greater than 0, then after step S4 is completed, the entire system can be controlled to repeat steps S1, S2, and S3 multiple times in the order described above, each time using the first cleaning agent, namely, hot water. This circulation can enhance the removal effect of water-soluble and heat-soluble dirt. After multiple cycles are completed, preparations can be made for the injection of the second cleaning agent. Specifically, solenoid valve 3 is closed, and the waste liquid collected in the previous step, such as the first cleaning agent and dirt, is discharged from the liquid reservoir 1. A second cleaning agent, such as a diethyl carbonate solution, is then added to the liquid reservoir 1 from its supply source. The second cleaning agent in the liquid reservoir 1 is then injected into the negative pressure cup 6 through the infusion pipe 2 until it is full, providing a cleaning medium for decomposing grease or organic residues. After the negative pressure cup 6 is filled with the second cleaning agent, the solenoid valve 3 on the infusion pipe 2 can be closed to cut off the liquid passage between the liquid reservoir 1 and the negative pressure cup 6, ensuring that the negative pressure cup 6 remains full. At this time, the vacuum cup 6 is completely wrapped by the second cleaning agent, and the time is kept until the preset second static soaking time is reached. If 5 minutes are reached, the next step S5 is triggered.

[0045] Step S5, opening the solenoid valve 3, and using the negative pressure suction unit to suck the second cleaning agent in the negative pressure cup 6 and the infusion pipe 2, wherein the second cleaning agent includes diethyl carbonate (DEC);

[0046] As an embodiment, the use of the negative pressure suction unit to suck the second cleaning agent from the negative pressure cup 6 and the infusion pipeline 2 includes using a negative pressure suction unit of -80KPa to -90KPa to suck the second cleaning agent from the negative pressure cup 6 and the infusion pipeline 2.

[0047] Specifically, after the soaking time in step S4 has expired and a completion signal has been received, solenoid valve 3 on infusion pipe 2 can be opened, connecting negative pressure cup 6 with infusion pipe 2. Simultaneously, the negative pressure suction unit is activated, forcing the remaining second cleaning agent liquid, along with any dissolved or suspended grease, and organic residues, from the interior of negative pressure cup 6 and infusion pipe 2 at a pressure of -80 kPa to -90 kPa, through infusion pipe 2. This establishes a directional negative pressure flow, utilizing fluid shear force to remove dissolved or swollen organic contaminants and residual cleaning agent still adhering to the inner wall, thereby eliminating any residual liquid phase within negative pressure cup 6.

[0048] Step S6: Start the positive pressure purge unit to purge the infusion pipeline 2 and the negative pressure cup 6.

[0049] As an embodiment, after step S6, the method further includes cyclically executing steps S4 to S6 according to a preset second cycle number, wherein the second cycle number is at least 1 time.

[0050] Specifically, after the suction operation in step S5 is completed and the negative pressure suction unit is turned off, the positive pressure purge unit can be started to output a high-speed airflow, which flows through the interior of the infusion pipe 2 and the inner cavity of the negative pressure cup 6 for strong purge. That is, through the physical impact and shearing effect of the airflow, the second cleaning agent liquid film, oil film and trace organic solid residues that may be precipitated due to solvent volatilization remaining on the inner wall of the infusion pipe 2 and the inner wall of the negative pressure cup 6 are removed. At this time, the high-speed flow of gas is conducive to drying the residual solvent and providing physical cleaning. In addition, after the purge is completed, if the set number of the second cycle is greater than 0, the order of steps S4, S5 to S6 can be controlled to be repeated multiple times to enhance the cleaning effect of stubborn organic dirt.

[0051] Table 1: Cleaning methods of Examples and Comparative Examples

[0052]

[0053] See Figure 5 and Figure 6 As shown, Figure 5 This is a cleaning effect diagram of an embodiment of a method for cleaning a negative pressure forming cup provided by an embodiment of the present invention. Figure 6 This is a cleaning effect diagram of a comparative example of a method for cleaning a negative pressure cup provided by an embodiment of the present invention. According to the results in Table 1 above, when the embodiment in Table 1 above is adopted, that is, the steps S1 to S5 are performed, and the first cycle and the second cycle are both 1, the total time is 16 minutes. When the comparative example in Table 1 above is adopted, that is, only DEC is used for rinsing, and the number of rinsing cycles is 2, the total time is 25 minutes. In addition, the cleaning effect of the cleaning method of the embodiment in Table 1 above can be seen in Figure 5 The cleaning effect of the comparative cleaning method in Table 1 above is shown in Figure 6 shown.

[0054] A method for cleaning a formation negative pressure cup provided by an embodiment of the present invention further includes placing the negative pressure cup 6 in an environment of 42° C. to 48° C. for at least 2 hours to dry the negative pressure cup 6 at high temperature.

[0055] Specifically, after completing step S6, the processed negative pressure cup 6 can be removed from its cleaning station and placed in a constant temperature drying oven or a specific drying area with a preset temperature range of 42°C to 48°C, such as the specific drying area where the negative pressure cup 6 was originally placed. By controlling the temperature of the drying environment within the above range and keeping the negative pressure cup 6 in a static state for a constant static time of not less than 2 hours, the residual trace moisture and / or solvent molecules in the negative pressure cup 6 can be evaporated, which is conducive to the complete drying of the negative pressure cup 6 without leaving any potential corrosion or pollution sources.

[0056] The present invention provides a method for cleaning a formation negative pressure cup. The method comprises the following steps: first, closing the solenoid valve 3, injecting a first cleaning agent in a liquid storage tank 1 into a negative pressure cup 6 from an infusion pipe 2 until the cup is full, and completely immersing the negative pressure cup 6 in the first cleaning agent according to a first static soaking time; secondly, opening the solenoid valve 3, using a negative pressure suction unit to suck the first cleaning agent in the negative pressure cup 6 and the infusion pipe 2, wherein the first cleaning agent includes hot water; then starting a positive pressure purge unit to purge the infusion pipe 2 and the negative pressure cup 6; then closing the solenoid valve 3, injecting a second cleaning agent in the liquid storage tank 1 into the negative pressure cup 6 from the infusion pipe 2 until the cup is full, and completely immersing the negative pressure cup 6 in the second cleaning agent according to a second static soaking time; then opening the solenoid valve 3, using the negative pressure suction unit to suck the second cleaning agent in the negative pressure cup 6 and the infusion pipe 2, wherein the second cleaning agent includes diethyl carbonate; and then starting the positive pressure purge unit to purge the infusion pipe 2 and the negative pressure cup 6. In this way, hot water, a first cleaning agent, is injected and allowed to soak, dissolving organic contaminants through thermal effects. This, combined with the soaking process, allows the contaminants to detach from the inner wall of the cup, dissolving and removing water-soluble dirt within the negative pressure cup 6. Suction and purge are then used to remove attached contaminants through directional fluid motion, and gas impact destroys the residual liquid film, clearing the residue within the negative pressure cup 6. Diethyl carbonate, a second cleaning agent, is then injected and allowed to soak, breaking down grease or organic residue. Suction and purge are then used to remove attached contaminants through directional fluid motion, leaving no residue within the negative pressure cup 6. This achieves the technical effect of thoroughly cleaning the negative pressure cup 6 and improving cleaning efficiency.

The negative pressure suction unit can be a vacuum pump, and the positive pressure purge unit can include an air compressor or a compressed gas source. The control processor integrated in the control panel 5 can be a microprocessor or a programmable logic controller, pre-installed with a control program for executing steps S1 to S8 above. The operation panel integrated in the control panel 5 includes a human-computer interaction interface. In addition, depending on the number of negative pressure cups 6 that need to be cleaned, a corresponding number of the above-mentioned liquid storage tanks 1, infusion pipes 2, solenoid valves 3, pressure supply sources 4, and control panels 5 can be provided to achieve cleaning of multiple negative pressure cups 6.

[0060] The present invention provides a device for cleaning a negative pressure cup. A liquid storage tank 1 and a negative pressure cup 6 are connected through an infusion pipe 2. A solenoid valve 3 is provided on the infusion pipe 2, and the solenoid valve 3 is located between the liquid storage tank 1 and the negative pressure cup 6. The liquid storage tank 1 is used to store a first cleaning agent and a second cleaning agent. A pressure source 4 is connected to the infusion pipe 2. The pressure source 4 includes a positive pressure purge unit and a negative pressure suction unit. A control panel 5 is connected to the solenoid valve 3 and the pressure source 4 respectively. By first closing the solenoid valve 3, the first cleaning agent in the liquid storage tank 1 is injected into the negative pressure cup 6 from the infusion pipe 2 until it is full. The negative pressure cup 6 is completely immersed in the first cleaning agent according to a first static soaking time. Secondly, the solenoid valve 3 is opened and a negative pressure is used. The suction unit draws the first cleaning agent, comprising hot water, from the negative pressure cup 6 and the infusion line 2. The positive pressure purge unit is then activated to purge the infusion line 2 and the negative pressure cup 6. The solenoid valve 3 is then closed, and the second cleaning agent from the liquid reservoir 1 is injected into the negative pressure cup 6 from the infusion line 2 until the cup is full. The negative pressure cup 6 is completely immersed in the second cleaning agent according to a second static soaking time. The solenoid valve 3 is then opened, and the negative pressure suction unit draws the second cleaning agent, comprising diethyl carbonate, from the negative pressure cup 6 and the infusion line 2. The positive pressure purge unit is then activated to purge the infusion line 2 and the negative pressure cup 6. The hot water of the first cleaning agent is injected and allowed to soak, dissolving organic contaminants through thermal effects. The static soaking allows the contaminants to separate from the inner wall of the cup, dissolving and removing water-soluble dirt from the negative pressure cup 6. Suction and purge then remove attached contaminants through directional fluid motion, and gas impact destroys the residual liquid film, clearing the residue from the negative pressure cup 6. Then, the second cleaning agent, diethyl carbonate, is injected and allowed to soak to decompose grease or organic residues. Then, suction and purge are used to remove attached contaminants through directional fluid movement, leaving no residue in the negative pressure cup 6. This achieves the technical effect of thoroughly cleaning the negative pressure cup 6 and improving cleaning efficiency.

[0063] The present invention provides an electronic device for cleaning a negative pressure cup. The electronic device comprises the following steps: first, closing the electromagnetic valve 3, injecting a first cleaning agent in a liquid storage tank 1 into a negative pressure cup 6 from an infusion pipe 2 until the cup is full, and completely immersing the negative pressure cup 6 in the first cleaning agent according to a first static soaking time; second, opening the electromagnetic valve 3, using a negative pressure suction unit to suck the first cleaning agent in the negative pressure cup 6 and the infusion pipe 2, wherein the first cleaning agent includes hot water; then starting a positive pressure purge unit to purge the infusion pipe 2 and the negative pressure cup 6; then closing the electromagnetic valve 3, injecting a second cleaning agent in the liquid storage tank 1 into the negative pressure cup 6 from the infusion pipe 2 until the cup is full, and completely immersing the negative pressure cup 6 in the second cleaning agent according to a second static soaking time; then opening the electromagnetic valve 3, using the negative pressure suction unit to suck the second cleaning agent in the negative pressure cup 6 and the infusion pipe 2, wherein the second cleaning agent includes diethyl carbonate; and then starting the positive pressure purge unit to purge the infusion pipe 2 and the negative pressure cup 6.
