Description

Technical Field

[0001] The invention relates to the technical field of electronic circuit board cleaning, and in particular to an electronic circuit board surface cleaning device based on the electrostatic adsorption principle. Background Art

[0002] At present, the cleaning of electronic circuit boards mainly relies on physical methods such as electrostatic adsorption, traditional air blowing and brushes. Electrostatic adsorption technology attracts dust and impurities attached to the surface of electronic circuit boards by generating an electrostatic field, and is widely used in various electronic equipment production environments. Compared with traditional cleaning methods, electrostatic cleaning equipment can effectively reduce damage to electronic components and improve cleaning efficiency due to its non-contact and low-damage characteristics. Therefore, electrostatic adsorption has gradually become a commonly used cleaning method in the electronics industry.

[0003] However, the existing electrostatic adsorption cleaning equipment still has some defects in practical applications. First, with the increase in the number of cleaning times, impurities are prone to accumulation on the surface of the equipment. Although static electricity can adsorb most dust and impurities, it is difficult to completely clean the equipment itself, which will cause the cleaning effect to gradually decrease during continuous use. In addition, the impurities adsorbed on the surface of the equipment are difficult to clean automatically, and manual maintenance and cleaning are often required regularly, which consumes a lot of manpower and time. Frequent manual cleaning not only affects production efficiency, but also increases maintenance costs. In some environments with high cleanliness requirements, this cleaning method is also difficult to ensure that secondary pollution is completely avoided. At the same time, most traditional electrostatic cleaning equipment lacks effective self-cleaning functions in design, resulting in the accumulation of residues inside the equipment after long-term use, and the need to replace or clean key components. This further increases the difficulty of maintenance and shortens the service life of the equipment. Summary of the invention

[0020] like Figure 3 As shown, the sliding bracket 1 includes a base plate 11, an inclined beam 12, a support plate 13 and a slide rail 14; the base plate 11 is in contact with the ground, the inclined beam 12 is installed at both ends of the base plate 11, and the two ends of the slide rail 14 are respectively connected to the inclined beam 12; the support plate 13 is installed between the slide rail 14 and the base plate 11; a spacing is set between the sliding bracket 1 and the shell 4, and the distance of the spacing is the sum of the width value of the rectangular slide groove 33 and the width value of the connecting arm 24.

[0021] like Figure 2 and Figure 3 As shown, arcuate edges 141 extend from both ends of the slide rail 14, and the arcuate edges 141 are movably engaged with the adsorption plate 2; the height of the upper end of the arcuate edge 141 is higher than the adsorption plate 2, and at the same time can clamp the adsorption plate 2, and the curvature of the arcuate edge 141 is 180°, so as to ensure that the adsorption plate 2 can be flipped under the continuous drive of the connecting arm 24 after being engaged with the arcuate edge 141.

[0022] like Figure 3 and Figure 6 As shown, a rectangular groove 131 is provided on the surface of the support plate 13, and the rectangular groove 131 is used to provide space for the weight block 23 set at the lower end of the adsorption plate 2 to move, thereby preventing combination obstacles, and at the same time providing support for the slide rail 14 to improve the stability of the slide rail 14.

[0023] A limit strip 142 is provided on the side of the slide rail 14 that contacts the adsorption plate 2; in order to prevent instability of the adsorption plate 2 during the sliding process on the surface of the slide rail 14, a limit strip 142 is provided, and a groove is provided at the lower end of the sliding cylinder 21, and the sliding cylinder 21 is fixedly connected to the adsorption plate 2, so that the sliding cylinder 21 does not roll but slides on the surface of the slide rail 14, and the limit strip 142 can well limit the sliding of the adsorption plate 2.

[0024] like Figure 6As shown, sliding cylinders 21 are installed at both ends of the adsorption plate 2, and a card groove 22 is provided on the surface of the sliding cylinder 21, and a groove engaged with the limit strip 142 is provided at the lower end of the sliding cylinder 21; a weight block 23 is installed at the bottom end of the adsorption plate 2, and a connecting arm 24 is installed on the side wall of the adsorption plate 2, and the connecting arm 24 is perpendicular to the adsorption plate 2, and a card block 25 is provided at the other end of the connecting arm 24, and the card block 25 is connected to the driving component 3; the card groove 22 provided on the surface of the sliding cylinder 21 is used to provide a clear The starting point and end point of the sliding of the cleaning plate 26, that is, when the adsorption plate 2 reaches the position of the arc edge 141, the transmission belt 37 continuously drives the connecting arm 24 to move, and then the adsorption plate 2 begins to flip, driving the electronic circuit board to separate from the adsorption plate 2, and through gravity, the cleaning plate 26 pushes the electronic circuit board to separate on the one hand, and on the other hand, the adsorption plate 2 is self-cleaned; a weight block 23 is provided at the bottom end of the adsorption plate 2, which is used to stabilize the surface of the adsorption plate 2 to prevent tipping due to insufficient friction.

[0025] In some embodiments, a dust suction component can be set at both ends of the adsorption plate 2. The dust suction component can be a dust suction device that can absorb dust. According to the actual application situation, the dust suction component can be set to a smaller cylindrical structure, which can be selectively placed in the sliding cylinder 21. Then, when the adsorption plate 2 rotates, on the one hand, after the electrostatic adsorption is completed, the electronic circuit board can be separated from the adsorption plate 2 by increasing the inclination angle of the adsorption plate 2 and the sliding bracket 1. On the other hand, during the separation process of the electronic circuit board, the cleaning plate 26 can automatically slide down according to gravity, and at the same time assist the electronic circuit board to separate from the adsorption plate 2. The cleaning plate 26 also scrapes away impurities on the surface of the adsorption plate 2 after the electronic circuit board is electrostatically adsorbed, until it is scraped to both ends, and the impurities are adsorbed by the dust suction component to achieve single cleaning.

[0026] like Figure 2 and Figure 7 As shown, a cleaning plate 26 is installed on the surface of the adsorption plate 2 , and both ends of the cleaning plate 26 are inserted into the card slot 22 .

[0027] like Figure 4 and Figure 5As shown, the driving assembly 3 includes a transverse frame 31, a sliding block 32, a left-turn wheel 34, a right-turn wheel 35, a motor 36, a transmission belt 37 and a crossbeam 39; the transverse frame 31 is installed on the side wall of the shell 4, the sliding block 32 is installed in the transverse frame 31, a rectangular slide groove 33 is installed on the surface of the sliding block 32, the rectangular slide groove 33 is located outside the transverse frame 31, and the rectangular slide groove 33 is slidably connected to the block 25; the left-turn wheel 34 and the right-turn wheel 35 are installed on the side wall of the transverse frame 31 through the crossbeam 39, the output shaft of the motor 36 is rotatably connected to the right-turn wheel 35, and a connecting block 38 is provided on the surface of the transmission belt 37, and the connecting block 38 is fixedly connected to the sliding block 32.

[0028] The sliding length of the sliding block 32 in the transverse frame 31 is greater than the length of the slide rail 14 , and the length of the slide rail 14 is greater than the length of the adsorption plate 2 .

[0029] During operation, the motor 36 is started, and the motor 36 rotates to drive the right-turning wheel 35 to rotate. The right-turning wheel 35 drives the connecting block 38 on the surface of the transmission belt 37 through the transmission belt 37. The connecting block 38 is fixedly connected to the sliding block 32, thereby driving the sliding block 32 to slide inside the transverse frame 31. The clamping block 25 is clamped in the rectangular slide groove 33. When the rectangular slide groove 33 slides to both ends, since the length of the transverse frame 31 is greater than the length of the slide rail 14, the adsorption plate 2 is driven to flip under the clamping of the arc edge 141. The connecting arm 24 is perpendicular to the adsorption plate 2, and the block 25 will slide in the rectangular chute 33. At this time, due to gravity, the cleaning plate 26 slides down from top to bottom, along the surface of the adsorption plate 2, pushing the electronic circuit board to detach from the adsorption plate 2, and cleaning the surface of the adsorption plate 2 to prevent impurities from remaining; since the electrostatic generator is installed inside the adsorption plate 2, the side of the electronic circuit board to be cleaned needs to fit the surface of the adsorption plate 2 until the cleaning plate 26 slides to the other side. Once the cleaning is completed, the motor 36 can be adjusted to perform the next cleaning. The description herein is provided to enable ordinary technicians in the field to implement or use the present disclosure. For ordinary technicians in the field, various modifications to the present disclosure will be obvious, and the general principles defined herein can be applied to other variations without departing from the scope of the present disclosure. Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the broadest scope consistent with the principles and novel features disclosed herein.
