[0002] In the production of supercapacitor injection, the infusion system is an important component to achieve injection. The cup holder of the infusion system is directly connected to the capacitor during the injection process. After the injection is completed, a certain amount of electrolyte will remain in the cup of the cup holder, which needs to be cleaned before injection can be performed again.

[0003] At present, the cup holder is mainly cleaned by immersion and flushing. The cup holder is immersed in a cleaning agent and dried after cleaning. This method uses a large amount of cleaning agent, and there will be residual liquid inside and outside the cup after immersion, which will also increase the time required for drying. At the same time, the immersion and flushing method will cause a certain amount of splashing of the cleaning medium, which is not easy to be directly carried out on the capacitor injection production line with cleanliness requirements. An independent area needs to be set up, which increases the transportation time and is not conducive to improving production efficiency. Therefore, those skilled in the art provide an automated online cleaning mechanism for an infusion system to solve the problems raised in the above background technology. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1

[0031] See also Figures 1 to 4As shown, an automated online cleaning mechanism for an infusion system in an embodiment of the present invention comprises a machine platform 1, a mounting frame 2 is fixed above the machine platform 1, a movable lifting assembly 5 is arranged at the upper end of the mounting frame 2, a mounting plate 9 is installed at the lower end of the movable lifting assembly 5, clamping assemblies 6 are arranged on both sides of the mounting plate 9, the movable lifting assembly 5 can drive the mounting plate 9 to be lifted, lowered and moved laterally, a sleeve cup holder 8 is clamped between the two clamping assemblies 6, the sleeve cup holder 8 adopts the existing technical structure, and is composed of a plurality of sleeve cups, and the upper and lower ends of the sleeve cups are respectively provided with a liquid injection port and a liquid outlet.

[0032] Among them, the movable lifting component 5 and the clamping component 6 both adopt the existing technical structure. The movable lifting component 5 can use a gear rack conveying mechanism for horizontal movement and a cylinder for lifting. The clamping component 6 can use a cylinder to drive the clamping plate to move for clamping.

[0033] A discharge assembly 4 is provided below the mounting frame 2, and an input assembly 7 is provided between the lower end surface of the mounting plate 9 and the cup holder 8. The input assembly 7 is connected to the liquid inlet end of the cup in the cup holder 8 and is used to inject a cleaning agent and an inert gas into the cup holder 8, wherein the cleaning agent is an electrolyte cleaning agent and the inert gas is nitrogen.

[0034] Specifically, the input assembly 7 includes two independent input plates 71, and a plurality of input heads 72 are provided on the lower end surface of the input plate 71. The input heads 72 can be connected to the liquid inlet end of the cup set in the cup set rack 8. Both ends of the input plate 71 are provided with input connectors 73 connected to the plurality of input heads 72. The input ports of the two input connectors 73 are used to connect the inert gas and the cleaning agent respectively. The input assembly 7 has two input plates 71, and the number of input heads 72 below a single input plate 71 is set to half the number of liquid injection ports above the cup set rack 8.

[0035] During cleaning, step one: the input plate 71 first injects a cleaning agent into the cup holder 8 to clean out most of the electrolyte, and then proceeds to step two: an inert gas is introduced for sweeping and blowing to blow out the residual liquid in the cup. At the same time, the high-speed airflow can also dry the cup. Cleaning steps one and two can be repeated multiple times. Repeating the cleaning steps can improve the cleaning effect. Cleaning can be completed using a small amount of electrolyte cleaning agent and nitrogen purge. The steps are simple, efficient, and low in cost.

[0036] In addition, in order to prevent mechanical collision between the input assembly 7 and the cup holder 8 when the mounting plate 9 is lowered, a plurality of buffer rods 74 are fixedly connected between the upper end surface of the input plate 71 and the mounting plate 9. The buffer rods 74 are spring-damped buffer rods that can effectively play a buffering role, thereby preventing mechanical collision.

[0037] Embodiment 2

[0038] Based on Example 1, please refer to Figures 5 to 7As shown, the discharge component 4 includes a mounting platform 41 fixed to the mounting frame 2, and a plurality of liquid collecting rows 42 and gas collecting rows 43 are respectively fixed on both sides of the upper end surface of the mounting platform 41. The upper ends of the liquid collecting rows 42 and the gas collecting rows 43 are both provided with liquid through ports, which can be connected to the liquid outlet ends of the cups in the cup rack 8. Through the setting of the discharge component 4, the cleaned gas and liquid can be discharged in a centralized manner, which is convenient for centralized treatment and subsequent recycling.

[0039] Specifically, the length of a single gas collecting row 43 is half of that of the liquid collecting row 42, and the outer ends of the gas collecting rows 43 on both sides are commonly connected to a gas discharge head 46; one end of the multiple liquid collecting rows 42 is commonly connected to a liquid discharge head 44, and the other end is commonly connected to a liquid level detection component 47, and a pneumatic valve 45 is fixed to the liquid outlet end of the liquid discharge head 44. The liquid collecting row 42 is used to discharge the cleaning agent, and the flow rate of the cleaning agent does not need to be too high, so an integrated long structure is adopted, and a single liquid discharge head 44 can meet the demand. Since the gas collecting row 43 is used to discharge inert gas, the inert gas is mainly used for sweeping and its introduction speed will be higher than the introduction speed of the cleaning agent. In order to ensure smooth gas discharge, the gas collecting row 43 is set with a short length, and gas discharge heads 46 are set at both ends to ensure smooth gas discharge. The discharged gas can be collected by a gas storage tank connected to the gas discharge head 46 (not shown).

[0040] Among them, the liquid level detection component 47 includes a connecting tube 471 connected to multiple liquid collection rows 42, one end of the connecting tube 471 is fixedly connected to a vertical detection tube 472, and the outer end of the detection tube 472 is provided with a liquid level sensor 473. The liquid level detection component 47 is set to detect the residual liquid inside the liquid collection row 42. The detection height of the liquid level sensor 473 is the height of the bottom end of the liquid outlet end of the cup holder 8 entering the liquid collection row 42. When the pneumatic valve 45 of the liquid discharge head 44 is opened to discharge liquid, the liquid level is lowered until the pneumatic valve 45 is closed after the liquid level sensor 473 is triggered, thereby ensuring that a certain amount of liquid remains inside the liquid collection row 42, so that there is no need to consume additional cleaning agent to refill the liquid collection row 42 when cleaning again, which effectively saves cleaning agent and reduces costs.

[0041] In addition, residual liquid may drip during the transfer of the cup rack 8. In order to collect the liquid, a liquid collecting tank 3 is provided at the upper end of the machine 1 just below the discharge assembly 4. The liquid collecting tank 3 is funnel-shaped and the lower end is connected to the external waste liquid storage tank. The setting of the liquid collecting tank 3 facilitates the collection of the dripping residual liquid.

[0042] Working principle: During cleaning, the mobile lifting assembly 5 first drives the cup holder 8 to move horizontally, aligns and docks half of the cup holder 8 with the liquid collecting row 42 of the discharge assembly 4. After docking, the cleaning agent and the cup holder are introduced into the input plate 71 at the docking position for cleaning. At this time, the pneumatic valve 45 is in a closed state. After cleaning, the pneumatic valve 45 opens to discharge liquid, and the liquid is discharged to the liquid level detection assembly 47 and then closed after being triggered. The mobile lifting assembly 5 drives the cup holder 8 to rise, and adjusts the cup holder 8 to a state that it is directly opposite to the discharge assembly 4 and docks. At this time, The cleaned part of the cup holder 8 is docked with the gas collecting row 43, and the uncleaned part is docked with the liquid collecting row 42. Nitrogen is introduced into the input plate 71 of the cleaned part for sweeping, and the residual liquid is blown out by the high-speed gas to dry the cup. The cleaning agent is introduced into the input plate 71 of the uncleaned part for cleaning. After the sweeping and cleaning are completed, the mobile lifting assembly 5 drives the cup holder 8 to move so that the part that has just been cleaned is docked with the gas collecting row 43 for nitrogen sweeping. After sweeping, a cleaning work is completed. The steps can be repeated many times to ensure the cleaning effect.

[0043] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
