[0024] In the following description, embodiments of the circuit board surface cleaning device of the present invention will be described with reference to the accompanying drawings.

[0025] Figure 1-4This invention illustrates a circuit board surface cleaning device according to an embodiment of the present invention, comprising a conveying platform 1; a cleaning box 2 is fixedly connected to the top of the conveying platform 1, a displacement slide 3 is slidably connected to the top of the cleaning box 2, a stepper motor 7 is fixedly installed on the rear side of the top of the cleaning box 2, a threaded rod 8 is fixedly connected to the output shaft of the stepper motor 7, the displacement slide 3 is threadedly connected to the surface of the threaded rod 8, a guide rod 9 is fixedly connected to the top of the cleaning box 2, and the displacement slide 3 is slidably connected to the surface of the guide rod 9. Through the coordinated use of the stepper motor 7, the threaded rod 8, and the guide rod 9, the displacement slide 3 can be driven to move back and forth on the top of the cleaning box 2, so that the brush head 53 can move back and forth, thereby making the surface of the circuit board evenly cleaned and improving the cleaning range of the cleaning device. A lifting frame 4 is provided above the displacement slide 3, and limit rods 10 are fixedly connected to the four corners of the top of the displacement slide 3. The lifting frame 4 is slidably connected to the surface of the limit rods 10, and a cleaning assembly 5 is provided below the lifting frame 4. The cleaning assembly 5 includes components fixedly installed in the inner cavity of the lifting frame 4. A DC motor 51 is included, with a rotating rod 52 fixedly connected to its output shaft. A brush head 53 is fixedly connected to the bottom of the rotating rod 52. An electric telescopic rod 54 is fixedly installed on the left side of the lifting frame 4, with its output end fixedly connected to the top of the displacement slide 3. The electric telescopic rod 54 allows the lifting frame 4 and the DC motor 51 to be pushed up and down, thus adjusting the height of the brush head 53 and the cleaning force. A dust collection unit is located on the left side of the top of the dust collection box 2. Component 6, the vacuuming assembly 6 includes a fixed tube 61 fixedly connected to the inner cavity of the displacement slide 3, a rotating rod 52 passing through the inner cavity of the fixed tube 61, a telescopic tube 62 slidably connected to the inner cavity of the fixed tube 61, a dust collection cover 63 fixedly connected to the bottom of the telescopic tube 62, a brush head 53 rotatably connected to the dust collection cover 63 through a bearing, a vacuum cleaner 64 fixedly installed on the right side of the top of the dust cleaning box 2, a vacuum cleaner 64 having an air inlet end connected to a vacuum pipe 65, and the end of the vacuum pipe 65 away from the vacuum cleaner 64 connected to the fixed tube 61.

[0026] Working Principle: In use, the user conveys the circuit board through the feeding platform 1. The circuit board reaches the inner cavity of the dust removal box 2. Then, the DC motor 51, the electric telescopic rod 54, and the vacuum cleaner 64 are started. The DC motor 51 drives the brush head 53 to rotate through the rotating rod 52. The electric telescopic rod 54 drives the dust collection assembly 6 to move downward, causing the rotating rod 52, the telescopic tube 62, and the brush head 53 to slide downward. Finally, the brush head 53 contacts the surface of the circuit board to clean the dust on the surface. The vacuum cleaner 64 is turned on and uses the suction pipe 65 to clean the air inside the fixed tube 61 and the telescopic tube 62. Air is drawn in, allowing air to flow from the telescopic tube 62 and the dust collection hood 63 into the fixed tube 61 and the suction tube 65. At the same time, the dust brushed off is sucked up and collected into the dust collection box of the vacuum cleaner 64. While the brush head 53 is brushing, the stepper motor 7 starts and drives the threaded rod 8 to rotate. Since the threaded rod 8 and the displacement slide 3 are in a threaded engagement transmission state, the displacement slide 3 slides on the top of the dust cleaning box 2. By controlling the forward and reverse rotation of the threaded rod 8 through the stepper motor 7, the displacement slide 3 slides back and forth on the top of the dust cleaning box 2, thereby enabling the brush head 53 to clean the surface of the circuit board back and forth.

[0027] In summary, this circuit board surface cleaning device, through the combined use of the lifting frame 4 and the cleaning component 5, cleans the circuit boards conveyed from the conveying platform 1 to the inner cavity of the cleaning box 2. At the same time, the dust suction component 6 is set to suck up and collect the dust under the cleaning, thereby achieving a high degree of cleanliness and preventing dust from overflowing.
