[0032] At present, the agitator commonly used in the production of PCBA cleaning agent on the market is an agitator with a propeller or a blade. Such an agitator will make the cleaning agent move from top to bottom when stirring the cleaning agent, and a vortex will be formed on the surface of the liquid surface of the cleaning agent. The movement trajectory will cause part of the air to be introduced into the cleaning agent, thereby forming air bubbles remaining in the cleaning agent. When the cleaning agent is used, the pressure of the spray will be reduced due to the remaining air bubbles, thereby affecting the cleaning efficiency of the cleaning agent.
[0033] Based on this, the present application provides a PCBA cleaning agent production device. The PCBA is the abbreviation of Printed Circuit Board Assembly, which means printed circuit board assembly. The PCBA cleaning agent is a cleaning agent applied to the PCBA. The PCBA cleaning agent production device of the present application uses a centrifugal agitator, and a through hole is formed in the bottom and the side wall of the agitator. When the agitator stirs the cleaning agent, the movement trajectory of the cleaning agent becomes from bottom to top, and the liquid surface of the cleaning agent does not form a vortex, thereby avoiding the mixing of air in the cleaning agent and improving the cleaning efficiency of the cleaning agent.
[0034] The following references Figure 1 and Figure 2 The PCBA cleaning agent production device of the embodiment of the present application is described.

[0036] The beneficial effects of the PCBA cleaning agent production device of the embodiment of the application can be shown as follows: by arranging the first stirrer 180 and arranging the first through hole 181 and the second through hole 182 on the first stirrer 180, the cleaning agent can move from bottom to top during stirring, and no vortex is formed on the liquid surface of the cleaning agent, so that air is avoided from being mixed into the cleaning agent, and the cleaning efficiency when the cleaning agent is used is improved. By directly connecting the stirring rod 160 with the driving motor 150, the driving motor 150 can directly provide power to the stirring rod 160, the loss of kinetic energy is reduced, and the stirring efficiency of the stirrer is improved.
[0037] For example, in some embodiments, reference is made to Figure 1 and Figure 2In the embodiment, the cleaning agent is a PCBA cleaning agent, the carrier barrel 120 is a cylindrical inner shell, which is more conducive to stirring the cleaning agent by the stirrer, the through opening is semicircular, the driving motor 150 is fixed to the top of the carrier barrel 120, and the through opening is directly below the driving motor 150, so that the stirring rod 160 connected with the driving motor 150 can extend into the carrier barrel 120 through the through opening, and the driving motor 150 is directly connected with the stirring rod 160, so that the driving motor 150 can provide the stirring rod 160 with stirring power to the greatest extent, thereby improving the stirring efficiency. The end portion of the stirring rod 160 away from the through opening is sleeved with the first stirrer 180, and the first stirrer 180 is relatively fixed with the stirring rod 160, so as to prevent the first stirrer 180 from being separated from the stirring rod 160 by accident. The first stirrer 180 is a separate stirrer, and therefore does not have a propeller or a blade. The bottom of the first stirrer 180 is provided with a first through hole 181 for sucking the cleaning agent upward during stirring. The side wall of the first stirrer 180 is provided with four second through holes 182, the four second through holes 182 are opposite to each other in pairs, and the second through holes 182 are communicated with the first through hole 181, so that the cleaning agent sucked into the first through hole 181 can be smoothly sprayed in the horizontal direction from the second through holes 182 to the surrounding.
[0038] It should be noted that the number of the second through holes 182 in the side wall of the first stirrer 180 can also be three or five, and the specific number can be adjusted according to actual needs. The positions of the second through holes 182 do not necessarily have to be opposite to each other, and can be staggered upward and downward.
[0039] It can be understood that the PCBA cleaning agent production device of the present application further comprises a second stirrer 170, the second stirrer 170 is sleeved on the stirring rod 160, the second stirrer 170 is located directly above the first stirrer 180, and the second stirrer 170 is relatively fixed with the stirring rod 160.
[0040] For example, in some embodiments, with reference to Figure 3 In the embodiment, the second stirrer 170 is sleeved directly above the first stirrer 180, so as to further stir the cleaning agent after being stirred by the first stirrer 180, thereby improving the stirring effect. The second stirrer 170 is also fixed with the first stirring rod 160, so as to be synchronized with the first stirrer 180.
[0041] It can be understood that the side wall of the second stirrer 170 is provided with a third through hole 171, the top of the second stirrer 170 is provided with a fourth through hole 172, the third through hole 171 is communicated with the fourth through hole 172, and the third through hole 171 and the fourth through hole 172 are used for guiding the flow direction of the cleaning agent.
[0042] For example, in some embodiments, with reference to Figure 3In the embodiment, the side wall of the second stirrer 170 is provided with four third through holes 171, the four third through holes 171 are opposite to each other in pairs, and the top of the second stirrer 170 is provided with five fourth through holes 172, the fourth through holes 172 communicate the top and the bottom of the second stirrer 170, and at the same time, the fourth through holes 172 communicate with the third through holes 171, so that the fourth through holes 172 guide the upward flow of the cleaning agent sprayed from the second through hole 182 of the first stirrer 180, and then the third through holes 171 spray the cleaning agent horizontally to the four directions, and thus the second stirrer 170 cooperates with the first stirrer 180 to realize the upward movement of the cleaning agent.
[0043] It should be noted that the third through holes 171 are not necessarily opposite to each other in pairs, but can be staggered in an up-down direction.
[0044] It can be understood that the production device also includes a hopper 100 and a first drainage pipe 110, the hopper 100 is arranged above the material loading barrel 120, one end of the first drainage pipe 110 is arranged in the material loading barrel 120, and the other end is connected with the hopper 100, and the hopper 100 is used for putting an auxiliary agent into the material loading barrel 120.
[0045] For example, in some embodiments, with reference to Figure 1 and Figure 2 In the embodiment, the hopper 100 is arranged at the top of the material loading barrel 120 and communicates with the material loading barrel 120 through the first drainage pipe 110, so that the non-liquid auxiliary agent of the cleaning agent is put into the material loading barrel 120 through the hopper 100, and the hopper mouth of the hopper 100 is small, which can avoid too much impurities entering the material loading barrel 120 through the hopper mouth.
[0046] It can be understood that the PCBA cleaning agent production device also includes a reflux structure, the reflux structure includes a pump body 130 and a second drainage pipe 140, the pump body 130 is arranged at the bottom of the material loading barrel 120, the pump body 130 communicates with the material loading barrel 120 through an input end, one end of the second drainage pipe 140 is arranged above the hopper 100, and the other end of the second drainage pipe 140 is connected with the pump body 130, and the reflux structure is used for guiding the cleaning agent from the bottom of the material loading barrel 120 to the hopper 100.
[0047] For example, in some embodiments, with reference to Figure 1 and Figure 2In the embodiment, one end of the second flow pipe 140 is arranged above the hopper 100, the other end of the second flow pipe 140 is connected with the pump body 130, the pump body 130 is arranged at the bottom of the material loading barrel 120 and communicates with the material loading barrel 120 through an input end, when the driving motor 150 drives the stirring rod 160 to rotate the first stirrer 180 and the second stirrer 170, the pump body 130 also draws the cleaning agent from the bottom of the material loading barrel 120 to the hopper 100 through the second flow pipe 140, and then the hopper 100 returns the drawn cleaning agent to the material loading barrel 120, so that the components of the cleaning agent are fully mixed, and at the same time, since the hopper 100 is used for putting the non-liquid cleaning agent, the hopper port may be blocked, and the cleaning agent returned through the second flow pipe 140 can drive the non-liquid cleaning agent to flow into the material loading barrel 120 through the hopper 100, so that the return structure can also keep the hopper port unblocked, and the pump body 130 is provided with a switch device, which can be closed to maintain the device when there is no stirring work.
[0048] It can be understood that the size of the second stirrer 170 is greater than that of the first stirrer 180.
[0049] For example, in some embodiments, the size of the second stirrer 170 is greater than that of the first stirrer 180 (not shown in the figure), so that the fourth through hole 172 of the second stirrer 170 can better provide upward force for the cleaning agent sprayed from the second through hole 182 of the first stirrer 180.
[0050] It can be understood that the production device of the application further comprises a feeding assembly arranged at the top of the material loading barrel 120, and the feeding assembly is used for conveying the cleaning agent into the material loading barrel 120.
[0051] For example, in some embodiments, the feeding assembly is installed at the top of the material loading barrel 120, and the process of inputting the required stirring cleaning agent into the material loading barrel 120 by the feeding assembly is completely sealed, which can effectively avoid excessive contact of the input cleaning agent with the outside world, ensure that air is not introduced into the cleaning agent during feeding, reduce the air bubbles mixed in the cleaning agent, and improve the cleaning efficiency of the cleaning agent. Different from the hopper 100, the feeding assembly is usually used for putting the liquid cleaning agent, so as to realize simultaneous feeding of the cleaning agent liquid and the non-liquid cleaning agent, and improve the stirring efficiency.
[0052] It can be understood that the feeding assembly comprises a third flow pipe 190, the feeding assembly communicates with the material loading barrel 120 through the third flow pipe 190, and one end of the third flow pipe 190 communicating with the material loading barrel 120 is provided with a first filter screen.

When the feeding assembly feeds the carrier barrel 120, the liquid pump is opened to pump the cleaning agent in the feeding barrel into the carrier barrel 120, thereby realizing the feeding of the cleaning agent. The port of the end of the third drain pipe 190 extending into the carrier barrel 120 through the sixth through hole is provided with a filter screen to filter out impurities remaining in the cleaning agent.
[0054] It can be understood that the production device of the application further comprises a filtering assembly, the filtering assembly comprising a fourth drain pipe, a second filter screen and a filtering barrel, the second filter screen being arranged at the barrel opening of the filtering barrel, one end of the fourth drain pipe being connected with the pump body and the other end being arranged above the second filter screen.
[0055] For example, in some embodiments, the pump body is provided with a first output end and a second output end, the first output end being connected with the second drain pipe and the second output end being connected with the fourth drain pipe. However, after the cleaning agent stirring operation is completed, the fully stirred cleaning agent in the carrier barrel 120 is pumped out through the fourth drain pipe, and the pumped-out cleaning agent enters the filtering barrel (not shown in the drawings) through the second filter screen, thereby realizing the re-filtering operation of the stirred cleaning agent. The filtering barrel is used to collect the cleaning agent filtered by the second filter screen and flowing out of the fourth drain pipe, so as to facilitate the subsequent use of the cleaning agent.
[0056] According to the production system of the second aspect of the application, the PCBA cleaning agent production device of the first aspect of the application is used.
[0057] According to the production system of the application, by arranging the first stirrer 180 and arranging the first through hole 181 and the second through hole 182 on the first stirrer 180, the cleaning agent moves from bottom to top during stirring, and no vortex is formed on the liquid surface of the cleaning agent, thereby avoiding the air being mixed into the cleaning agent and improving the cleaning efficiency when the cleaning agent is used. By connecting the stirring rod 160 and the driving motor 150, the driving motor 150 can directly provide power performance to the stirring rod 160, thereby reducing the loss of kinetic energy and improving the stirring efficiency of the stirrer. By introducing the PCBA cleaning agent production device of the application, the efficiency of the production system of the application is further improved, and the risk of introducing impurities into the cleaning agent is reduced.
