According to the invention, the air flow is used for blowing the residual cleaning agent on the surface of the PCB downwards through the compression air bag 401, so that the converging dripping efficiency of the residual cleaning agent on the surface of the PCB is accelerated, the residual cleaning agent on the surface of the PCB when the PCB enters the next cleaning tank 2 is reduced, the problem that the service period of the cleaning agent is short due to the mutual mixing of different cleaning agents is solved, and the specific process is as follows:
When the first driving piece 106 drives the movable plate 102 and the hooks 103 to descend to put the placing frame 3 with the PCB into the cleaning tank 2, the distance between the movable plate 102 and the fixed plate 101 is increased, the movable plate 102 moves downwards to stretch the air bag 401, the internal volume of the air bag 401 is increased, external air is pumped into the air bag 401 through the one-way air pipe 402, when the first driving piece 106 drives the movable plate 102 and the hooks 103 to ascend to lift the placing frame 3 with the PCB from the cleaning tank 2, the movable plate 102 moves upwards to compress the air bag 401, at the moment, the one-way air pipe 402 is closed, the compressed air in the air bag 401 is blown downwards through the first air blowing pipe 403 and the second air blowing pipe 404 to blow the residual cleaning agent on the surface of the PCB into the cleaning tank 2, the converging dropping efficiency of the residual cleaning agent on the surface of the PCB is accelerated, the residual cleaning agent on the surface of the PCB is reduced, the occurrence of different cleaning agents is delayed when the PCB enters the next cleaning tank 2, the cleaning effect for the surface of the PCB is guaranteed, the use cycle of the cleaning agent is prolonged.
After the first driving piece 106 drives the hook 103 to lift the placing frame 3 from the cleaning tank 2, residual cleaning agent on the surface of the PCB is blown down and drips back into the cleaning tank 2, small cleaning agent droplets cannot drip down, a sagging phenomenon is formed on the lower side of the PCB, at this time, the first driving piece 106 drives the placing frame 3 to continuously move upwards and contact with the baffle 405, the placing frame 3 is blocked and limited through the baffle 405 in a curved shape, the upper left side and the upper right side of the placing frame 3 are downwards bent, meanwhile, the deformation groove 3002 on the upper side of the placing frame 3 is stretched and expanded, the deformation groove 3002 on the lower side of the placing frame 3 is compressed, the lower side of the placing frame 3 drives the PCB to approach towards the middle of the placing frame 3, the lower side of the PCB is enabled to be contacted with each other, the small cleaning agent droplets on the lower side of the placing frame 3 are mutually converged to form large droplets and then drip back into the cleaning tank 2, the residual cleaning agent on the surface of the PCB when entering the next cleaning tank 2 is reduced, and the service cycle of the cleaning agent is further prolonged.
Example 3: on the basis of the embodiment 1, as shown in fig. 1,2 and 10, a guide 501 is further included; two bilaterally symmetrical guides 501 are fixedly connected in each cleaning tank 2; each guide 501 is provided with a guide portion 50101; a plurality of diversion parts 50102 which are symmetrically distributed in front-back are arranged on each guide 501; each of the flow guiding portions 50102 is provided to face the middle of the cleaning tank 2.
The upper side of each guide 501 is provided in an inclined shape.
When the PCB board is pushed by the cleaning agent to be in an inclined state, the cleaning agent is guided to the surfaces of the PCB boards on the left side and the right side of the placing frame 3 through the guide parts 50101 and the guide parts 50102, so that the surfaces of the PCB boards are uniformly washed, the cleaning effect on the PCB boards is further enhanced, meanwhile, the guide 501 which is in an inclined state is arranged on the upper side, impurities which are washed down on the PCB boards are prevented from being accumulated on the surfaces of the guide 501, the impurities can be fully brought into the electric control water tank 202 by the cleaning agent to be filtered, and the cleaning effect of the cleaning agent on the surfaces of the PCB boards is guaranteed.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
