As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5As shown, a circuit board surface treatment device includes a box body 1 with a conveyor belt assembly 2 and a conveyor belt assembly 3 fixedly connected thereto, a cleaning box 5 and a conveyor belt assembly 3 8 fixedly connected to one end of the box body 1, an ultrasonic generator 6 fixedly connected to one end of the cleaning box 5, a plurality of cleaning brackets 9 fixedly connected to one end of the conveyor belt assembly 3 8, a cleaning clamp 10 slidably connected to one end of the cleaning bracket 9, and a spring 11 fixedly connected to one end of the cleaning clamp 10 and the cleaning bracket 9;

[0031] The conveyor belt assembly 2 can deliver the circuit board into the device for cleaning. During cleaning, a special cleaning liquid for the circuit board is stored in the cleaning box 5. Then the circuit board is vertically inserted into the cleaning bracket 9 from above. At this time, the rubber cleaning clamp 10 can clamp the circuit board from both sides. Then the conveyor belt assembly 3 8 is started to move the circuit board to the other end. During the movement, the ultrasonic generator 6 works to perform ultrasonic cleaning. Because there are multiple cleaning brackets 9 on the conveyor belt assembly 3 8, multiple circuit boards can be erected at the same time for cleaning to improve cleaning efficiency.

[0032] Because the lower end of the circuit board is cleaned first when it is placed in the cleaning liquid, and then the upper part of the circuit board can be cleaned without any obstruction during the clamping and movement process, all parts of the circuit board can be cleaned in the cleaning liquid, and the cleaning liquid combined with the ultrasonic generator 6 can clean off the adhering fine dust and flux and other objects to improve the cleaning effect.

[0033] In this embodiment, one end of the box body 1 is fixedly connected to an electric swing arm 12, the movable end of the electric swing arm 12 is fixedly connected to a telescopic rod 13, the movable end of the telescopic rod 13 is fixedly connected to a double-headed push rod 14, the movable end of the double-headed push rod 14 is fixedly connected to a side clamping claw 16, and one end of the double-headed push rod 14 is fixedly connected to a micro switch 15 and an anti-drop plate 17;

[0034] When the circuit board moves into the device following the conveyor belt assembly 2, the circuit board will fall on the anti-fall plate 17, and then continue to move and squeeze one end of the micro switch 15. At this time, the double-headed push rod 14 is started to retract, and the circuit board is clamped from both sides by the side clamping claw 16. Then the electric swing arm 12 drives the double-headed push rod 14 to rotate 90 degrees, allowing the circuit board to stand upright above the cleaning bracket 9 on one side. Then the telescopic rod 13 is extended, and the circuit board is installed on the cleaning bracket 9 for cleaning, and the material is loaded quickly.

[0035] In this embodiment, the two sides of the box body 1 are respectively fixedly connected to the lifting motor 19 and the anti-deflection bracket 27, one end of the anti-deflection bracket 27 is rotatably connected to a plurality of sprockets 20, one end of the sprocket 20 is transmission-connected to a chain 26, one end of the chain 26 is slidingly connected to the anti-deflection bracket 27, and one end of the sprocket 20 on one side is fixedly connected to the power output end of the lifting motor 19;

[0036] One end of the chain 26 is rotatably connected to a plurality of suspension rods 21, one end of the suspension rod 21 is fixedly connected to a telescopic rod 22, one end of the telescopic rod 22 is fixedly connected to a plumb bob 23, the movable end of the telescopic rod 22 is fixedly connected to a double-headed push rod 24, and the movable end of the double-headed push rod 24 is fixedly connected to the double-headed push rod 24.

[0037] When the lifting motor 19 rotates, it can drive the chain 26 to rotate counterclockwise, thereby driving the multiple telescopic rods 22 to move counterclockwise. When one telescopic rod 22 moves to the bottom, it can extend to clamp the circuit board in the cleaning box 5 below through the double-headed push rod 24 and the side clamp 25. Then the telescopic rod 22 retracts and the lifting motor 19 works. After moving to the top, the double-headed push rod 24 expands, allowing the circuit board to fall onto the conveyor belt assembly 2 3;

[0038] During the movement of the chain 26 , the anti-deflection bracket 27 can support the lower side of the chain 26 from below to prevent the chain 26 from falling. At the same time, the plumb bob 23 can keep the telescopic rod 22 vertical by relying on its weight.

[0039] In this embodiment, an ion blower 28 and a hot air blower 29 are fixedly connected to both ends of the box body 1. The ion blower 28 and the hot air blower 29 can dry the circuit board under the telescopic rod 22 and remove static electricity to prevent damage.

[0040] In this embodiment: the conveyor belt assembly 2 can deliver the circuit board into the device for cleaning. During cleaning, a special cleaning liquid for the circuit board is stored in the cleaning box 5, and then the circuit board is vertically inserted above the cleaning bracket 9 from above. At this time, the rubber cleaning clamp 10 can clamp the circuit board from both sides, and then the conveyor belt assembly 3 8 is started to move the circuit board to the other end. During the movement, the ultrasonic generator 6 works to perform ultrasonic cleaning. Because there are multiple cleaning brackets 9 on the conveyor belt assembly 3 8, multiple circuit boards can be erected at the same time for cleaning, improving the cleaning efficiency;

[0041] Furthermore, because the lower end of the circuit board is cleaned first when it is placed in the cleaning liquid, and then the upper end is cleaned without any obstruction during the clamping and moving process, all parts of the circuit board can be cleaned in the cleaning liquid, and the cleaning liquid combined with the ultrasonic generator 6 can clean away the adhering fine dust and solder flux and other objects to improve the cleaning effect;

[0042] When the circuit board follows the conveyor belt assembly 2 and moves into the device, the circuit board will fall on the anti-fall plate 17, and then continue to move and squeeze one end of the micro switch 15. At this time, the double-headed push rod 14 is activated to retract, and the side clamping claws 16 are used to clamp the circuit board from both sides. Then the electric swing arm 12 drives the double-headed push rod 14 to rotate 90 degrees, allowing the circuit board to stand upright above the cleaning bracket 9 on one side. Then the telescopic rod 13 is extended, and the circuit board is installed on the cleaning bracket 9 for cleaning, and the material is loaded quickly.

[0043] When the lifting motor 19 rotates, it can drive the chain 26 to rotate counterclockwise, thereby driving the multiple telescopic rods 22 to move counterclockwise. When one telescopic rod 22 moves to the bottom, it can extend to clamp the circuit board in the cleaning box 5 below through the double-headed push rod 24 and the side clamp 25. Then the telescopic rod 22 retracts and the lifting motor 19 works. After moving to the top, the double-headed push rod 24 expands, allowing the circuit board to fall onto the conveyor belt assembly 2 3;

[0044] During the movement of the chain 26, the anti-deflection bracket 27 can support the lower side of the chain 26 from below to prevent the chain 26 from falling. At the same time, the plumb bob 23 can keep the telescopic rod 22 vertical by relying on its weight.

[0045] The ion blower 28 and the hot air blower 29 can dry the circuit board below the telescopic rod 22 and remove static electricity to prevent damage.

[0046] Example 2:

[0047] A circuit board surface treatment device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-5 As shown,

[0048] In this embodiment, a wedge-shaped groove 18 is formed at one end of the side clamping jaw 25 and the side clamping jaw 1 16. The side clamping jaw 25 and the side clamping jaw 1 16 are made of rubber. The wedge-shaped groove 18 can better clamp the edge of the circuit board to prevent it from falling off.

[0049] In this embodiment, the lower end of the cleaning box 5 is fixedly connected to a filter box 7, and one end of the conveyor belt component 2 3 is fixedly connected to a material receiving baffle 4. The filter box 7 can centrally recover impurities after cleaning, and the material receiving baffle 4 can allow the circuit board to slide toward the conveyor belt component 2 3 to prevent it from falling and being damaged.

Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
