At this time, the water flow will flow through the water inlet pipe 12 into the first diversion groove 13 and the second diversion grooves 14 in sequence, and then be sprayed out through the water outlet grooves 15 into the cleaning groove 11 to achieve the purpose of cleaning the circuit board. At the same time, the drainage component will drain the water inside the cleaning groove 11 to prevent water overflow. Through the settings of the cleaning tank 1 and the cleaning groove 11, the displacement of the circuit board during cleaning can be effectively reduced, and the overall stability of the device is effectively enhanced. At the same time, through the settings of the first diversion groove 13, the plurality of groups of second diversion grooves 14 and the water outlet grooves 15, the cleaning dead corners of the circuit board can be effectively reduced, and the problem of incomplete cleaning and defects of the circuit board caused by too many cleaning dead corners can be effectively reduced, further enhancing the overall stability of the device.

[0026] Refer to Figure 3 And Figure 5As shown, a pair of fixed rods 2 are fixedly connected to the side wall of the cleaning tank 1 close to the inlet pipe 12; a same first fixing plate 21 is fixedly connected to the ends of the pair of fixed rods 2; a liquid storage tank 22 is fixedly connected to the top of the first fixing plate 21; a liquid inlet pipe 23 is fixedly connected to the side wall of the inlet pipe 12 close to the liquid storage tank 22; the inlet pipe 12 and the liquid inlet pipe 23 are communicated with each other; the bottom of the liquid storage tank 22 is communicated with the liquid inlet pipe 23; a plug 24 is used in cooperation with the middle of the liquid inlet pipe 23; when it is necessary to further clean the circuit board during work, cleaning liquid can be pre-added into the liquid storage tank 22, and then the plug 24 can be pulled out of the liquid inlet pipe 23 during use.

At this time, the air flow will sequentially pass through the first air guide groove 31, the third air guide grooves 34 and then be ejected from the second air guide groove 32. Then, when the circuit board is taken out after being cleaned, the air ejected from the second air guide groove 32 will blow off the water stains attached to the circuit board, so as to reduce the processing time of the subsequent circuit board. At the same time, the power supply of the heating wire 33 can also be turned on. At this time, the heating wire 33 will heat the air passing through the third air guide grooves 34 to pre-dry the circuit board. Through the settings of the air inlet 3, the first air guide groove 31, the third air guide grooves 34 and the second air guide groove 32, it is possible to effectively reduce the situation that when the circuit board is taken out after being cleaned, due to the incomplete setting of the device as a whole for removing residual moisture, too much moisture remains on the circuit board, effectively reducing the subsequent processing time of the circuit board, further enhancing the usability and stability of the device as a whole. At the same time, through the setting of the heating wire 33, the circuit board can be pre-dried when taken out, further enhancing the usability of the device as a whole.

[0028] Refer to Figure 2 As shown in the figure, a pair of rotating grooves 4 are provided in the middle of the cleaning box 1; the pair of rotating grooves 4 are symmetrically arranged; rotating shafts 43 are fixedly connected to the middle of the pair of rotating grooves 4; cleaning rollers 41 are rotatably connected to the rotating shafts 43; a plurality of bristles 42 are installed on the side walls of the cleaning rollers 41; during operation, when the circuit board is inserted into or pulled out of the cleaning tank 11, the bristles 42 will contact the surface of the circuit board. At this time, the bristles 42 will drive the cleaning rollers 41 and the rotating shafts 43 to start rotating inside the rotating grooves 4 due to the friction with the circuit board. At this time, different bristles 42 will sweep away the impurities or residual moisture on the surface of the circuit board to further enhance the cleaning effect. Through the settings of the rotating shafts 43, the cleaning rollers 41 and the bristles 42, the moisture and impurities attached to the surface of the circuit board after cleaning can be further reduced, and the situation that too much moisture remains on the circuit board due to the incomplete setting of moisture removal can be further reduced, effectively reducing the subsequent processing time of the circuit board, further enhancing the usability and stability of the device as a whole. At the same time, due to the setting of the bristles 42, the solid impurities attached to the surface of the circuit board can be swept away to a certain extent, further improving the cleaning effect of the device as a whole.

[0029] Refer to Figure 2 and Figure 6 As shown, the fixing component includes a sliding groove 5; the sliding groove 5 is opened in the middle of the cleaning box 1 and there are a pair of them; the pair of sliding grooves 5 are symmetrically arranged; a push rod 51 is slidably connected to the middle of each of the pair of sliding grooves 5; a second fixing plate 53 is fixedly connected to the end of the push rod 51; a plurality of springs 52 are fixedly connected to the side wall of the second fixing plate 53 close to the cleaning tank 11; the end of the spring 52 is fixedly connected to the side wall of the cleaning tank 11; the push rod 51 is arranged in the middle of the spring 52 close to the sliding groove 5; anti-slip pads 54 are fixedly connected to the side walls of the pair of second fixing plates 53 close to each other; when working, when the circuit board needs to be placed into the cleaning tank 11, first pull the push rod 51 in the direction away from the cleaning box 1. At this time, the push rod 51 will drive the second fixing plate 53 and the anti-slip pad 54 to move in sequence, so that the pair of anti-slip pads 54 move away from each other. Then the circuit board can be placed into the cleaning tank 11. When the circuit board reaches the required position, release the push rod 51. At this time, the second fixing plate 53 and the anti-slip pad 54 will bounce back to their original positions due to the elasticity of the spring 52 and clamp the circuit board between the pair of anti-slip pads 54 to achieve the purpose of fixing the circuit board. Through the arrangement of the push rod 51, the second fixing plate 53 and the anti-slip pad 54, it can effectively reduce the situation that the circuit board falls and displaces during cleaning due to the incomplete fixing of the device as a whole to the circuit board, thus causing the situation of incomplete cleaning, defects and bumps of the circuit board, further enhancing the overall stability of the device. At the same time, through the arrangement of the spring 52, the pair of anti-slip pads 54 can continuously clamp the circuit board, further reducing the occurrence of the above situations.

[0030] Refer to Figure 1 and Figure 2 As shown, a pair of splash-proof pads 6 are installed at the position of the inner side wall of the cleaning box 1 close to the top of the cleaning tank 11; the pair of splash-proof pads 6 are symmetrically arranged; during work, the splash-proof pads 6 can play a role in reducing the water splashing out of the cleaning tank 11 by themselves. Through the arrangement of the splash-proof pads 6, the situation of water splashing out during cleaning can be effectively reduced, and the situation that the overall device affects the working environment during the cleaning work can be effectively reduced, further enhancing the overall usability of the device.

[0031] Refer to Figure 2As shown, the drainage assembly includes a third diversion groove 7; the third diversion groove 7 is provided at the bottom of the cleaning tank 1; the third diversion groove 7 is inclined; a water outlet hole 71 is formed in the middle of the cleaning tank 1; the water outlet hole 71 is communicated with the cleaning tank 11; during operation, the third diversion groove 7 and the water outlet hole 71 will automatically play a guiding role to achieve the purpose of discharging waste liquid. At the same time, a wastewater treatment device or a water circulation device can also be connected to the water outlet hole 71 to achieve the purpose of recycling water resources. Through the setting of the third diversion groove 7 and the water outlet hole 71, the situation that waste water cannot be discharged due to the incomplete overall drainage setting of the device can be effectively reduced, further enhancing the overall reliability of the device.

[0032] Refer to Figure 1 And Figure 6 As shown, a pair of the anti-slip pads 54 are both made of rubber; a pair of the anti-splash pads 6 are both made of rubber; the anti-slip pads 54 and the anti-splash pads 6 made of rubber can effectively reduce the situation that the circuit board is damaged due to the frequent contact between the anti-slip pads 54 and the anti-splash pads 6 and the circuit board, further improving the overall stability of the device.

[0033] Working principle: When working, first insert the circuit board into the inside of the cleaning tank 11 with the wiring part facing up and the circuit part facing down, then use the fixing component to fix the wiring part of the circuit board, and then connect the pre-prepared water source and water pump to the inlet pipe 12. Then start the power supply of the water pump to pump water into the inlet pipe 12. At this time, the water flow will flow through the inlet pipe 12 and into the first diversion groove 13 and the second diversion groove 14 in sequence, and then be sprayed out to the cleaning tank 11 through the water outlet groove 15 to achieve the purpose of cleaning the circuit board. At the same time, the drainage component will drain the water inside the cleaning tank 11 to prevent water overflow. When further cleaning of the circuit board is required during work, cleaning liquid can be added to the liquid storage tank 22 in advance. Then, when in use, the plug 24 can be pulled out of the liquid inlet pipe 23. At this time, the cleaning liquid inside the liquid storage tank 22 will flow into the inlet pipe 23 through the liquid inlet pipe 23. At this time, the water flow inside the inlet pipe 23 will carry the cleaning liquid into the cleaning tank 11 to achieve a better cleaning effect. When it is not necessary to use the cleaning liquid to clean the circuit board, the plug 24 can be inserted into the liquid inlet pipe 23. At this time, the cleaning liquid inside the liquid storage tank 22 will no longer flow out. First, connect the pre-prepared air pump to the air inlet 3, and then start the power supply of the air pump to pump air into the first air guide groove 31. At this time, the air flow will pass through the first air guide groove 31 and the third air guide groove 34 in sequence and then be sprayed out by the second air guide groove 32. Then, when the circuit board is taken out after being cleaned, the air sprayed out by the second air guide groove 32 will blow off the water stains attached to the circuit board to reduce the subsequent processing time of the circuit board. At the same time, the power supply of the heating wire 33 can also be turned on. At this time, the heating wire 33 will heat the air passing through the third air guide groove 34 to pre-dry the circuit board. When the circuit board is inserted into or pulled out of the cleaning tank 11, the bristles 42 will contact the surface of the circuit board. At this time, the bristles 42 will drive the cleaning roller 41 and the rotating shaft 43 to start rotating in the rotating groove 4 due to the friction with the circuit board. At this time, different bristles 42 will sweep away the impurities or residual water on the surface of the circuit board to further enhance the cleaning effect. When the circuit board needs to be placed into the cleaning tank 11, first pull the ejector rod 51 away from the cleaning box 1. At this time, the ejector rod 51 will drive the second fixing plate 53 and the anti-slip pad 54 to move in sequence, so that a pair of anti-slip pads 54 move away from each other. Then the circuit board can be placed into the cleaning tank 11. When the circuit board reaches the required position, release the ejector rod 51. At this time, the second fixing plate 53 and the anti-slip pad 54 will bounce back to their original positions due to the elasticity of the spring 52 and clamp the circuit board between a pair of anti-slip pads 54 to fix the circuit board. The splash-proof pad 6 can play a role in reducing the water splashing out inside the cleaning tank 11 by itself. The third diversion groove 7 and the water outlet holes 71 will play a guiding role by themselves to drain the waste liquid. At the same time, a waste water treatment device or a water circulation device can also be connected to the water outlet holes 71 to recycle water resources.

[0034] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this utility model creation.
