Description

Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing technology, and specifically relates to a circuit board cleaning device. Background Technology

[0002] A circuit board cleaning device is a specialized device for cleaning dust, solder residue, oxides, and other contaminants from printed circuit boards (PCBs). These contaminants can affect the functionality of the circuit board or even cause short circuits or component failure.

[0003] Existing circuit board cleaning devices involve placing the circuit board to be cleaned in a designated position on a movable platform, which then moves the board. During this movement, fixed brushes mounted on supports remove dust, solder slag, and oxides generated during processing, facilitating subsequent circuit board processing. However, in actual use, the fixed position of the cleaning brushes results in a single-direction brushing motion, leaving some areas uncleaned. Often, after the first cleaning, the circuit board needs to be manually rotated and then cleaned a second time, which is time-consuming, labor-intensive, and places a heavy workload on the processing personnel, reducing the efficiency of circuit board processing. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a circuit board cleaning device that can drive the circuit board to move horizontally back and forth during the cleaning process. By cooperating with a rotating brush, it can quickly and stably clean and scrape the circuit board from multiple directions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a circuit board cleaning device, including a frame, a cleaning platform provided on the upper surface of the frame, and evenly distributed support legs provided on the lower surface of the frame. The upper surface of the cleaning platform is provided with symmetrically distributed guide rails, and sliding seats are slidably arranged on the upper side of each guide rail. A sliding table is provided between the sliding seats, and the upper surface of the sliding table is provided with symmetrically distributed guide rails. A placement plate is slidably arranged between the guide rails, and evenly distributed placement grooves are formed on the upper surface of the placement plate. A support is provided on the upper surface of the cleaning platform, and a drive box is provided on the support. A cleaning brush is provided on the front side of the lower surface of the drive box via a rotating shaft, and a cleaning brush is provided on the rear side of the lower surface of the drive box via a rotating shaft. The drive box contains symmetrically distributed motors, and the output shafts of the motors are fixed to adjacent rotating shafts via couplings.

[0006] As a further improvement of this utility model, the lower surface of the cleaning table is provided with symmetrically distributed supports, and an adjusting screw is rotatably arranged between the supports. The slide table is threadedly connected to the adjusting screw. A motor is installed on the cleaning table, and the output shaft of the motor is fixed to the adjusting screw by a coupling. A rotating rod is rotatably arranged inside the slide table. Rotating cylinders are fixedly sleeved at both ends of the outer arc surface of the rotating rod. Sliding rods are slidably arranged inside the rotating cylinders, and the top ends of the sliding rods are rotatably connected to the placement plate. A worm gear is fixedly sleeved in the middle of the outer arc surface of the rotating rod. A worm is rotatably arranged on the lower side of the slide table. The worm is meshed with the worm gear. A motor is installed on the outer side of the slide table, and the output shaft of the motor is fixed to the worm by a coupling.

[0007] As a further improvement of this utility model, a control board is provided on the front side of the drive box, and motors one, two and three are all electrically connected to the control board.

[0008] As a further improvement of this utility model, the outer side of the drive box is provided with uniformly distributed jet pipes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the control board regulates the operation of motor three, causing the output shaft of motor three to drive the worm gear connected to it to rotate in both directions, so that the rotating cylinder drives the placement plate to slide back and forth between guide rail two through the slide rod that is slidably connected to it.

[0010] Secondly, the control board regulates the operation of motor one and motor two, causing the slide to move the circuit board placed on the placement plate. During the movement of the circuit board, the circuit board is cleaned by the rotation of cleaning brush one and cleaning brush two.

[0011] Third, the circuit board placed in the placement slot is moved back and forth by the constantly reciprocating placement plate, and then the circuit board is quickly and stably cleaned by the rotation of cleaning brush one and cleaning brush two.

[0012] Fourth, all jet pipes are connected to an external air pump, so that when cleaning the circuit board with cleaning brush one and cleaning brush two, the contaminants swept off the circuit board can be blown away by jets. Attached Figure Description

Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0017] like Figure 1 , 4 As shown, the system includes a frame 101, a cleaning table 103 on the upper surface of the frame 101, and evenly distributed support legs 102 on the lower surface of the frame 101. The upper surface of the cleaning table 103 is provided with symmetrically distributed guide rails 104. Sliding seats 105 are slidably disposed on the upper side of each guide rail 104. A slide table 201 is disposed between the slide seats 105. A symmetrically distributed guide rail 202 is disposed on the upper surface of the slide table 201. A placement plate 203 is slidably disposed between the guide rails 202. Evenly distributed placement grooves 204 are formed on the upper surface of the placement plate 203. A bracket 106 is disposed on the upper surface of the cleaning table 103. A drive box 107 is disposed on the bracket 106. A cleaning brush 112 is disposed on the front side of the lower surface of the drive box 107 via a rotating shaft. A cleaning brush 113 is disposed on the rear side of the lower surface of the drive box 107 via a rotating shaft.

[0018] As shown in Figure 2, the drive box 107 is equipped with symmetrically distributed motors 114, and the output shaft of the motors 114 is fixed to the adjacent rotating shaft by a coupling.

[0019] like Figure 1 , 2As shown, the lower surface of the cleaning table 103 is provided with symmetrically distributed supports 109, and an adjusting screw 110 is rotatably arranged between the supports 109. The slide table 201 is threadedly connected to the adjusting screw 110. A motor 111 is provided on the cleaning table 103, and the output shaft of the motor 111 is fixed to the adjusting screw 110 by a coupling.

[0020] like Figure 3 , 4 As shown, a rotating rod 205 is rotatably mounted inside the slide table 201. Rotating cylinders 206 are fixedly fitted at both ends of the outer arc surface of the rotating rod 205. Sliding rods 207 are slidably mounted inside each rotating cylinder 206, and the top ends of the sliding rods 207 are rotatably connected to the placement plate 203. A worm gear 208 is fixedly fitted in the middle of the outer arc surface of the rotating rod 205. A worm 209 is rotatably mounted on the lower side of the slide table 201, meshing with the worm gear 208. A motor 210 is mounted on the outer side of the slide table 201, and the output shaft of the motor 210 is fixed to the worm 209 via a coupling. like Figure 1 , 2 As shown, a control board 301 is provided on the front side of the drive box 107, and motors 111, 114, and 210 are all electrically connected to the control board 301.

[0021] In use, the circuit board to be cleaned is placed in the placement slot 204 on the placement plate 203. Then, the control board 301 controls the motor 210 to run, so that the output shaft of the motor 210 drives the worm 209 connected to it to rotate in a forward and reverse cycle. Then, through the meshing relationship between the worm 209 and the worm wheel 208, the rotating rod 205 where the worm wheel 208 is located rotates, so that the rotating rod 205 drives the rotating cylinders 206 at both ends of its outer arc surface to swing back and forth. The rotating cylinders 206, through the sliding rod 207 slidably connected to them, drive the placement plate 203 to slide back and forth between the guide rails 202. The control board 301 regulates the operation of motor 111 and motor 114, causing the output shaft of motor 114 to drive the shaft connected to it to rotate, which in turn drives cleaning brush 112 and cleaning brush 113 to rotate. The output shaft of motor 111 drives the adjusting screw 110 connected to it to rotate. The output shaft of the adjusting screw 110 drives the slide table 201 connected to it to slide between guide rail 104, causing the slide table 201 to move the circuit board placed on the placement plate 203. During the movement of the circuit board, the circuit board is swept and cleaned by the rotation of cleaning brush 112 and cleaning brush 113. During the cleaning process, the circuit board placed in the placement slot 204 is moved back and forth by the reciprocating placement plate 203, and then the circuit board is cleaned quickly and stably by the rotation of cleaning brush 112 and cleaning brush 213.

[0022] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, the drive box 107 has evenly distributed jet pipes 108 on its outer side. During the cleaning process, the jet pipes 108 are all connected to an external air pump, so that when cleaning the circuit board with cleaning brush one 112 and cleaning brush two 113, the contaminants swept off the circuit board can be blown away by air.
