Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
A circuit board immersion cleaning device comprises a cleaning barrel 1, wherein a water outlet pipe 2 and a water inlet pipe 3 are arranged at the bottom of the cleaning barrel 1, the cleaning barrel 1 comprises an outer barrel 101 and an inner barrel 102 arranged in the outer barrel 101 in a hanging mode, a sealing ring 4 connected with the inner side wall of the outer barrel 101 is sleeved on the outer side wall of the inner barrel 102, the side wall and the bottom wall of the inner barrel 102 located below the sealing ring 4 are of a net-shaped structure, and meanwhile a cross frame 22 used for supporting the bottom end of the inner barrel 102 is arranged in the outer barrel 101 to prevent the inner barrel 102 from collapsing due to extrusion of a circuit board.
In this embodiment, a drain pipe 5 is arranged on the side wall of the outer barrel 101 above the sealing ring 4, a support grid 6 is arranged at the bottom in the inner barrel 102, wherein the supporting grid 6 is connected with the inner bottom wall of the inner barrel 102 through a spring 7, the top of the supporting grid 6 is evenly provided with a convex block 8, a filter screen 9 is arranged in the inner barrel 102 above the supporting grid 6, wherein the top end of the side wall of the inner barrel 102 above the filter screen 9 is evenly provided with a U-shaped overflow port 10, the middle of the filter screen 9 is also provided with an inlet and an outlet 11, wherein the top of the inner barrel 102 is provided with a protective screen 12 for sealing the inlet and the outlet 11, the middle of the protective screen 12 is provided with a feeding pipe 13, one end of the protective screen 12 is hinged with the filter screen 9 through a hinge 14, wherein, the filter screen 9 is provided with a screw 15 passing through the other end of the protective net 12, and the screw 15 above the protective net 12 is screwed with a nut 16.
The top end of the side wall of the outer barrel 101 is bent towards the inner barrel 102 to form a horizontal part 17 positioned above the inner barrel 102, wherein the tail end of the horizontal part 17 is bent downwards to form a vertical part 18 positioned in the opening of the inner barrel 102, the bottom wall of the outer barrel 101 is further provided with a motor 19, a rotating shaft 20 of the motor 19 extends into the outer barrel 101 below the inner barrel 102, and the rotating shaft 20 is provided with a stirring blade 21.
In use the circuit board is placed in the inner tub 102 above the support grid 6 via the feed tube 13, and the cleaning liquid is injected into the outer barrel 101 through the water inlet pipe 3, so that the liquid flows into the inner barrel 102 through the apertures on the lower half side wall and the bottom wall of the inner barrel 102 to fill and soak the circuit board, at this time, the motor 19 drives the stirring blade 21 to rotate through the rotating shaft 20, thereby agitating the liquid in the outer barrel 101 under the inner barrel 102 to generate vortex, the surged liquid flows into the inner barrel 102 through the apertures on the lower half side wall and the bottom wall of the inner barrel 102 and agitates the circuit board above the support grid 6, so that the circuit board is agitated and cleaned together with the liquid, therefore, the purpose of improving the cleaning effect and efficiency is achieved, and the circuit board is not damaged because the stirring blades 21 do not directly stir the circuit board and are not in contact with the circuit board.
When the circuit boards are gradually added to the top of the support grid 6, the support grid 6 is extruded to move downwards under the influence of the gravity of the circuit boards to enable the support grid 6 to shrink, when the circuit boards are taken out after the circuit boards are washed, when the circuit boards on the upper half part of the inner barrel 102 are gradually reduced, the gravity of the circuit boards on the support grid 6 is also gradually reduced, the spring 7 is unfolded to push the support grid 6 to move upwards, and therefore the gap between the circuit boards on the top end face of the support grid 6 and the top of the washing barrel 1 is reduced, and people can conveniently reach the circuit boards to take out the circuit boards.
In the above process, when the vortex agitated by the stirring blade 21 drives the liquid in the inner barrel 102 to rotate, the impact force of the liquid can extrude the support grid 6, and the support grid 6 can extrude the spring 7 to contract and expand, so as to achieve the purpose of shaking the circuit board above the support grid 6 to make the circuit board fully contact with the liquid to improve the cleaning efficiency and effect.
As shown in figure 1, when the impurity adhered on the circuit board is separated from the circuit board during agitation cleaning, and the impurity can float on the liquid surface due to light weight, wherein when the liquid level in the inner barrel overflows the filter screen 9, the impurity can flow upwards through the aperture of the filter screen 9 and float on the top end surface of the liquid level, and when the liquid level overflows the overflow port 10, the impurity can flow into the space between the inner barrel 102 and the outer barrel 101 above the sealing ring 4 through the overflow port 10 to be stored, and then flows out through the drain pipe 5, thereby realizing the removal of the impurity obtained during the cleaning process of the circuit board, and the filter screen 9 can prevent the circuit board in the inner barrel 102 from flowing out from the top opening thereof due to the influence of the liquid surging. In the above process, objects above are prevented from falling into the gap between the inner tub 102 and the outer tub 101 by the horizontal part 17.
Meanwhile, after the washing is finished, the water outlet pipe 2 is opened to drain the liquid in the outer barrel 101, the liquid in the inner barrel 102 flows into the bottom of the outer barrel 101 through the apertures in the bottom of the side wall and the bottom wall of the inner barrel and is discharged through the water outlet pipe 2, so that the draining work of the product in the inner barrel 102 is realized, at the moment, the nut 16 is screwed off to enable the protective net 12 to slide out from the screw 15, the protective net 12 rotates around the hinge 14 to be rotated out from the opening of the vertical part 18, the purpose of opening the inlet and outlet 11 is realized, and people can take out a circuit board above the support grid 6 in the inner barrel 102 through the opened inlet and outlet 11.
The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
