DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] As Figure 1 A circuit board processing and cleaning device, including water tank 1, the inner end both sides of water tank 1 are installed with spray pipe 6, for spraying cleaning fluid to clean the two sides of circuit board, the outer end both sides of water tank 1 are installed with water box 61, water box 61 is communicated with spray pipe 6, water supply is carried out to spray pipe 6 by water box 61, water supply pipe 62 is installed at the outer end of water box 61, wherein, water supply pipe 62 can be connected with existing equipment such as water pump to supply cleaning fluid to water supply pipe 62, water supply pipe 62 is communicated with water box 61, drainage pipe is installed at the outer end of water tank 1, to facilitate the drainage of water in the water tank 1.

[0029] In the embodiment, as Figure 1 、 Figure 2 and Figure 3A support 2 is arranged at the upper end of the water tank 1, and a placing rack 3 is arranged at the inner side of the support 2. The circuit board to be cleaned is placed in the placing rack 3. A connecting rack 31 is fixed to the top of the placing rack 3. A hydraulic rod 21 is arranged at the upper end of the support 2, and the output end of the hydraulic rod 21 is fixed to the connecting rack 31. The extension and retraction of the hydraulic rod 21 can drive the placing rack 3 to ascend and descend through the connecting rack 31, so that the circuit board placed in the placing rack 3 can ascend and descend.

[0030] Two wipers are arranged at the lower end of the placing rack 3. The wipers wipe the cleaning liquid on the outer surface of the circuit board, so that the liquid remaining on the outer surface of the circuit board after cleaning is reduced. The wiper comprises two cleaning racks 4 arranged at the lower end of the placing rack 3. A sponge pad 41 is arranged on the side of the two cleaning racks 4 close to each other. When the two cleaning racks 4 are close to each other, the sponge pad 41 can contact the outer surface of the circuit board, so that the liquid on the outer surface of the circuit board is wiped.

[0031] Further, the side of the two cleaning racks 4 away from each other is provided with a mounting rack 5. The two ends of the mounting rack 5 are fixed to the support 2. A screw rod 51 is rotatably connected between the two mounting racks 5. A support rod 53 is fixed to the side of the two mounting racks 5 away from the screw rod 51. The two cleaning racks 4 are threadedly connected to the screw rod 51. The thread directions of the two cleaning racks 4 connected to the screw rod 51 are opposite. The support rod 53 penetrates the interior of the two cleaning racks 4. A servo motor 52 is arranged at the outer side of one mounting rack 5. The output shaft of the servo motor 52 is connected to the screw rod 51. The specific connection mode can be achieved by using the prior art. The support rod 53 supports and limits the two cleaning racks 4, so that the screw rod 51 can drive the two cleaning racks 4 to translate when the screw rod 51 rotates. At this time, the two cleaning racks 4 are close to or away from each other.

[0032] After the cleaning device is used to clean the circuit board, the circuit board to be cleaned is placed in the placing rack 3. The hydraulic rod 21 drives the placing rack 3 to descend. When the placing rack 3 and the circuit board enter the water tank 1, the spray pipe 6 sprays the cleaning liquid through the spray head to clean the circuit board in the placing rack 3. After cleaning, the hydraulic rod 21 drives the placing rack 3 to ascend. When the connecting rack 31 is above the wiper, the servo motor 52 drives the screw rod 51 to rotate. At this time, the two cleaning racks 4 are close to each other, so that the sponge pad 41 contacts the outer surface of the circuit board. The liquid remaining on the outer surface of the circuit board after cleaning is wiped, so that the liquid remaining on the outer surface of the circuit board is reduced, and the drying efficiency of the circuit board is improved.

[0033] After the circuit board is taken out from the placing rack 3, the two cleaning racks 4 continue to translate and approach each other, so that the two sponge pads 41 are squeezed to squeeze out the liquid absorbed in the sponge pads 41, and the wiping efficiency in the subsequent process is maintained.

[0034] In another embodiment, as Figure 4 and Figure 5 A baffle 32 is fixed on the inner end upper side of the placing rack 3 at the connection with the connecting rack 31, and the placement of the circuit board is limited by the baffle 32. A positioner is arranged on the lower side of the connecting rack 31, and the positioner and the baffle 32 can clamp one end of the circuit board placed in the placing rack 3, so as to keep the circuit board stable when placed in the placing rack 3.

[0035] Specifically, the positioner comprises a limiting plate 7 arranged on the lower side of the connecting rack 31. A pressing plate 71 is slidably connected to the side of the limiting plate 7 close to the baffle 32. A return spring 72 is connected between the pressing plate 71 and the limiting plate 7. The two ends of the return spring 72 are fixed to the pressing plate 71 and the limiting plate 7 respectively. The pressing plate 71 can be pushed by the elastic force of the return spring 72, so as to slide to the side close to the baffle 32, so that the pressing plate 71 tightly presses the circuit board.

[0036] The limiting plate 7 is slidably connected to the inside of the connecting rack 31 through a rectangular plate 701 fixed on the top of the limiting plate 7. An adjusting rod 8 is rotatably connected to the inside of the connecting rack 31. One end of the adjusting rod 8 extends to the outside of the connecting rack 31, and the adjusting rod 8 is threadedly connected with the rectangular plate 701. The rotation of the adjusting rod 8 can drive the rectangular plate 701 and the positioner to rise.

[0037] Further, the upper end of the pressing plate 71 is provided with an inclined surface, so that when the positioner rises as a whole, the inclined surface of the pressing plate 71 is in contact with the connecting rack 31, so that the pressing plate 71 slides into the inside of the limiting plate 7.

[0038] When the circuit board is placed in the placing rack 3, the circuit board is clamped by the baffle 32 and the positioner. During this process, the return spring 72 pushes the pressing plate 71 by the elastic force, so that the pressing plate 71 tightly presses the circuit board in the placing rack 3. The baffle 32 and the positioner clamp and fix one end of the circuit board, so as to keep the circuit board stable in the placing rack 3.

[0039] When the cleaning is completed and the circuit board in the placing rack 3 needs to be taken out, the adjusting rod 8 is rotated, so that the rectangular plate 701 drives the limiting plate 7 to rise. During this process, the pressing plate 71 slides into the inside of the limiting plate 7. When the positioner as a whole enters the connecting rack 31, the cleaned circuit board can be taken out from the placing rack 3.
