An embodiment of the utility model provides a cleaning system after heavy copper of PCB board, as shown in fig. 1, it is including wasing pond 100, flying to get a bus 200 and being used for placing the PCB board hang basket 300, washs pond 100 and can be the rectangular bodily form, and its inside loading has the water that is used for wasing the PCB board. The outer side surfaces of both sides of the cleaning pool 100 are respectively fixed with a supporting seat 400, the top of the supporting seat 400 is provided with a placing groove, both ends of the flying bar 200 in the length direction are respectively placed in the two placing grooves, and the hanging basket 300 is hooked on the flying bar 200. The takeoff bus 200 can be hung by the lifting device, the takeoff bus 200 hooked with the hanging basket 300 is placed at the top of the supporting seat 400, the hanging basket 300 invades into the water of the cleaning pool 100, and the hanging basket 300 and the PCB in the hanging basket 300 can be cleaned.

A support frame 500 is fixed on the top surface of the cleaning tank 100 near the back side, and a spray device is fixed on the top of the support frame 500 to lift the spray device to a certain height, so that the spray device sprays water to the flying bar 200. Therefore, this embodiment is through spray set to flying to a 200 shower water of minibar to wash the solution that drops on flying to a 200, make flying to a 200 and keep clean, when follow-up electroplating, just can not have other material to transfer to the PCB board on, can ensure the quality of PCB board. Meanwhile, the spraying device is arranged on the top surface of the cleaning pool 100 close to the back side, so that the spraying device can be prevented from interfering the lifting device to lift the take-off bar 200.

In some embodiments, the spraying device comprises a horizontally arranged water diversion pipe 510, a plurality of spraying pipes 520 connected with the water diversion pipe 510, and a spraying inlet pipe 530 connected with the water diversion pipe 510, wherein water enters the water diversion pipe 510 through the spraying inlet pipe 530, and is sprayed out of the spraying pipes 520 after being distributed through the water diversion pipe 510. The axial direction of water knockout drum 510 is parallel with the length direction of feiba 200, and shower 520 is evenly distributed along the axial direction of water knockout drum 510, so shower 520 can spray water to a plurality of positions on the length direction of feiba 200, and this can promote the cleaning performance.

Further, a washing inlet pipe 110 and a drain pipe 120 are connected to the washing tank 100, the washing inlet pipe 110 is used for adding water to the washing tank 100, and the drain pipe 120 can drain the waste water in the washing tank 100. The spray inlet pipe 530 is connected to the wash inlet pipe 110, which corresponds to a branch from the wash inlet pipe 110 to supply water to the spray inlet pipe 530, which can simplify the overall piping arrangement. Meanwhile, an electric control valve 540 is provided on the spray inlet pipe 530, and the electric control valve 540 can control the spray inlet pipe 530 to be turned on or off to spray the femto 200 at a proper time.

Further, a photoelectric switch is fixed in one of the two placement grooves, and the electric control valve 540 and the photoelectric switch are electrically connected to the controller. When the flying bar 200 is placed in the placing groove, the photoelectric switch is triggered, and the controller sends a control signal to the electric control valve 540 again, so that the electric control valve 540 is opened to spray and flush the flying bar 200. When flying when the chin 200 not place in the standing groove, photoelectric switch is not triggered, and the controller does not send control signal to electrical control valve 540, and electrical control valve 540 is in the closed condition, and shower 520 does not spray to flying chin 200 and washes, and this can avoid spray set to do unnecessary useless work.

In some embodiments, a front baffle 610 is secured to the top surface of wash tank 100 near the front side. When the spraying device works, water mainly splashes forward, and the front baffle 610 can play a role in blocking water splashing.

Furthermore, side baffles 620 are fixed on the top surfaces of the cleaning pool 100 close to the two side surfaces, through grooves 621 are formed in the side baffles 620, and the two ends of the flying bar 200 in the length direction are respectively located in the through grooves 621 of the two side baffles 620 and can move in the corresponding through grooves 621. The side baffles 620 can prevent water from splashing to both sides, and can enhance the water-retaining effect. Meanwhile, the through groove 621 does not block the lifting device from lifting the takeoff bar 200. According to actual needs, a rear baffle can be arranged on the back side of the spraying device to further strengthen the water retaining effect.

It should be noted that one of the side baffles is removed in fig. 1 to facilitate viewing of the internal structure of the cleaning tank 100.

In some embodiments, the top of the support base 400 is provided with two protrusions 410, and a placement groove is formed between the two protrusions 410, so that the end of the flying bar 200 in the length direction is placed between the two protrusions 410, and the protrusions 410 can better limit the movement of the flying bar 200, so that the flying bar 200 is stably placed on the top of the support base 400.

Further, both ends of the flying bar 200 in the length direction pass through the placing slots, i.e. pass through between the two protrusions 410 at the top of the two supporting seats 400. The bottom of the part of flying bar 200 that both ends passed the standing groove in length direction all is provided with string groove 210 to the couple hook of overhead hoist takes off bar 200.

The foregoing is a more detailed description of the present invention, taken in conjunction with the accompanying specific embodiments, and it is not intended to limit the invention to the specific embodiments described herein. To the utility model discloses to the ordinary technical person of technical field, under the prerequisite that does not deviate from the utility model discloses the design, can also make a plurality of simple deductions or replacement.
