Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0020] Referring to FIGS. (1-7), an automatic circuit board surface treatment device includes a workbench 1. A cleaning pool 5 is opened at the top of the workbench 1. Placement grooves 11 are arranged on both sides of the cleaning pool 5. A material rack 2 is arranged on the placement grooves 11. A plurality of material grooves 21 into which materials can be inserted are opened on the material rack 2. A moving mechanism 3 is arranged above the workbench 1. The moving mechanism 3 includes two parallel cross plates 31 and a moving plate 35. The cross plates 31 are supported by support columns 11, and sliding grooves 32 are opened on the sides of the two cross plates 31 close to each other. Both ends of the moving plate 35 are slidably connected to the sliding grooves 32. A first telescopic machine 36 is fixedly installed on the moving plate 35. A lifting plate 4 is fixedly installed on the telescopic end of the first telescopic machine 36.

[0021] Preferably, baffles 41 and support plates 42 are respectively arranged on both sides of the bottom of the lifting plate 4. There are two support plates 42, and a second telescopic machine 43 is arranged between the two support plates 42. Both sides of the second telescopic machine 43 are rotatably connected to the two support plates 42 through connecting rods 44 respectively. One of the connecting rods 44 is connected to the output end of a second motor 45 installed on the support plate 42. A suction cup rack 46 is fixedly installed on the telescopic end of the second telescopic machine 43. A plurality of suction cups are installed on the suction cup rack 46. One end of the suction cup is communicated with a vacuum pump through an air pipe.

[0022] Preferably, a screw rod 33 is rotatably arranged in one of the sliding grooves 32. The screw rod 33 penetrates through one end of the moving plate 35 and is screwed to the moving plate 35. One end of the screw rod 33 is connected to the output end of a first motor 34 installed in the cross plate 31.

[0023] Preferably, a plurality of spray heads 51 are arranged in the cleaning pool 5 in an array. The water outlet of the spray head 51 faces upward, and the water inlet is communicated with an external water pump through a water pipe. First limiting grooves 53 and second limiting grooves 54 are respectively opened on the front and rear inner walls of the cleaning pool 5. A cleaning roller 52 is arranged between the first limiting groove 53 and the second limiting groove 54.

[0024] Preferably, the cleaning roller 52 is composed of a rotating shaft 521 and a sponge layer provided on the outer surface of the rotating shaft 521. A gear 522 is installed at one end of the rotating shaft 521, and the other end extends into the motor box 523 and is connected to the output end of a motor provided in the motor box 523. The motor box 523 is slidably connected to the first limiting groove 53. A rack is provided at the bottom of the second limiting groove 54. The gear 522 is slidably connected to the second limiting groove 54 and meshes with the rack at the bottom of the second limiting groove 54.

[0025] Preferably, grooves for the cleaning roller 52 to enter are formed on the left and right sides of the inner wall of the cleaning pool 5. The groove on one side with a height less than the diameter of the cleaning roller 52 is an extrusion groove 55. The extrusion groove 55 can extrude the sponge layer of the cleaning roller 52 that is squeezed in. A water outlet groove 56 communicating with the cleaning pool 5 is formed at the bottom of the extrusion groove 55.

[0026] When the device is in use, the circuit board is inserted on the material slot 21 of the material rack 2, and the material rack 2 is placed on the placement slot 11. Another empty material rack 2 is placed on another placement slot 11. The first motor 34 is started to drive the screw 33 to rotate, driving the moving plate 35 to move along the sliding groove 32, driving the first telescopic machine 36 and the lifting plate 4 to move onto the material rack 2. The first telescopic machine 36 is started to drive the lifting plate 4 to descend, so that the baffle 41 is inserted into the gap between the circuit boards on the material rack 2 and fits with the circuit board close to the suction cup rack 46. The second telescopic machine 43 is started to drive the suction cup rack 46 to approach the circuit board, clamping the circuit board between the baffle 41 and the suction cup rack 46. At this time, the suction cup adheres to the circuit board. The vacuum pump connected to the suction cup is started to evacuate the inside of the suction cup, so that the suction cup adsorbs the circuit board. Then the circuit board is lifted upward from the material rack and driven to move to the cleaning pool 5. The second motor 45 is started to drive the second telescopic machine 43 and the circuit board adsorbed on the suction cup rack 46 to rotate 90 degrees, so that the circuit board faces the cleaning pool 5. The circuit board is driven to move downward into the cleaning pool 5 by the first telescopic machine 36 and the second telescopic machine 43. The water pump connected to the spray head 51 is started to pump water or cleaning agent into the spray head 51 and spray it to wash the surface of the circuit board. After the washing is completed, the motor in the motor box 523 is started to drive the rotating shaft 521 to rotate. The gear 522 on the rotating shaft 521 rotates on the rack on the second limiting groove 54, driving the rotating shaft and the motor box to slide along the first limiting groove and the second limiting groove. When passing under the circuit board, the sponge layer on the rotating shaft contacts the circuit board, adsorbing the remaining water stains on the circuit board. Then the cleaning roller enters the extrusion groove, and the upper and lower groove walls of the extrusion groove squeeze the sponge layer to squeeze out the adsorbed water. Then the circuit board is driven to leave the cleaning pool and placed on another empty material rack for storage.
