Description

Technical Field

[0001] This utility model relates to the field of PCB circuit board processing technology, specifically to a cleaning device for PCB circuit board processing that can uniformly dry the circuit board. Background Technology

[0002] Cleaning is a crucial step in the manufacturing process of PCBs (Printed Circuit Boards). With the rapid development of electronic technology, the application of PCBs is becoming increasingly widespread, and their complexity and precision are constantly increasing. During PCB manufacturing, processes such as soldering, surface mounting, and cutting often leave various contaminants on the board surface, including flux, solder, dust, and oil. These contaminants not only affect the appearance of the board but can also seriously impact its electrical performance, leading to faults such as poor soldering, short circuits, and open circuits.

[0003] Chinese patent publication number CN208373719U discloses a cleaning device for PCB circuit board processing, including a main body, a cleaning cavity, and a top cover. Through the inclusion of partitions, multiple sets of PCB circuit boards can be placed separately, avoiding the inability to clean the contacting side caused by placing two sets of PCB circuit boards in contact, thus increasing the cleaning area and making the cleaning more thorough and comprehensive. The included clamps can stably hold the PCB circuit boards to be cleaned, preventing them from falling due to ultrasonic vibration and reducing unnecessary contact between multiple sets of PCB circuit boards. The included heating wires can heat the cleaning process to meet the optimal cleaning temperature, resulting in better cleaning effects. The entire PCB circuit board processing cleaning device has a simple structure, is easy to operate, and achieves better results than traditional methods.

[0004] When the aforementioned patent document is used, the PCB circuit board is placed on a basket and fixed by the clamps on the basket before being placed into the cleaning chamber for cleaning. However, the aforementioned patent document does not take into account that because the fixed PCB circuit board is fixed, dead corner parts cannot be cleaned during cleaning, resulting in incomplete cleaning, leaving contaminant residue, which affects the electrical performance and reliability of the circuit board.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1 to 7As shown, this utility model provides a PCB circuit board processing cleaning device that can uniformly dry the circuit board. It includes a base 1, a top plate 2 on the top of the base 1, and a cleaning chamber 3 on the top of the base 1. A placement plate 4 is vertically movable within the cleaning chamber 3. A vertical drive component is provided within the cleaning chamber 3 to drive the placement plate 4 vertically. A clamping assembly 5 for fixing the circuit board is provided on the placement plate 4. An ultrasonic generator 8 is provided on one side of the cleaning chamber 3, and ultrasonic transducers 9 are provided on both sides of the ultrasonic generator 8. A water outlet pipe 10 is provided on the other side of the cleaning chamber 3, and a water pump 11 is provided on the water outlet pipe 10. The clamping assembly 5 includes a movable plate 51 that can move along the placement plate 4. A threaded drive component is provided on the placement plate 4 to drive the movable plate 51. A rectangular seat 52 is provided on one side of the movable plate 51 via a pivot. A movable rod 53 is vertically movably arranged within the rectangular seat 52. One end of the movable rod 53... A pressure plate 54 is provided, and a handle 55 is provided at the other end of the movable rod 53. A spring 56 is also sleeved on the movable rod 53. One end of the spring 56 abuts against the top of the pressure plate 54, and the other end of the spring 56 abuts against the inner wall of the rectangular seat 52. A rotating component 6 for driving the circuit board to rotate after clamping is provided on one side of the movable plate 51. A drying assembly 7 for drying the circuit board is provided on the top of the top plate 2. The drying assembly 7 includes a drying box 71 provided on the top of the top plate 2. A fan 72 is provided on the top of the drying box 71. A heating plate 73 is provided inside the drying box 71. A connecting pipe 74 is provided at the bottom of the drying box 71. A mounting plate 75 is provided at the bottom of the top plate 2. A main flow pipe 76 is provided at the bottom of the mounting plate 75. A reciprocating drive component for driving the main flow pipe 76 to move back and forth is provided on the mounting plate 75. One end of the main flow pipe 76 is connected to the connecting pipe 74. An air outlet 77 is provided at the bottom of the main flow pipe 76.

[0025] By placing the PCB circuit board on the placement plate 4, the threaded drive component is activated to move the movable plate 51 to a suitable position according to the size of the circuit board. Once the movable plate 51 is in the appropriate position, the handle 55 is pulled, causing the movable rod 53 and the pressure plate 54 to move upward and compress the spring 56, placing the PCB circuit board into the rectangular base 52. By releasing the handle 55, the spring 56 returns to its elastic deformation, causing the pressure plate 54 to fix the PCB circuit board. At this time, the vertical drive component is activated, driving the placement plate 4 to move into the cleaning chamber 3. The cleaning chamber 3 is filled with cleaning fluid, and the ultrasonic generator 8 is activated. The ultrasonic generator 8 converts the ultrasonic waves into mechanical vibrations through the ultrasonic transducer 9, allowing the cleaning fluid to thoroughly clean the PCB circuit board. At this time, the rotating component 6 drives the clamped circuit board to rotate, ensuring that all parts of the circuit board surface can fully contact the cleaning fluid for uniform cleaning. After cleaning, the vertical drive component returns to its initial state, driving the placement plate 4 to move upward, and the fan 72 is activated. After being heated by the heating plate 73, hot air is generated. Hot air is delivered to the surface of the circuit board through the connecting pipe 74 and the main pipe 76 to dry the circuit board. The main pipe 76 is driven by a reciprocating drive component to move back and forth on the surface of the circuit board, ensuring that the hot air evenly covers the surface of the circuit board, achieving uniform drying and improving the drying efficiency and quality.

[0026] See Figures 1 to 5 As shown, the rotating component 6 includes a drive box 61; the drive box 61 is disposed on one side of the moving plate 51, one end of the rotating shaft extends through one side of the moving plate 51 into the drive box 61, the extended end of the rotating shaft is provided with a worm gear 62, the drive box 61 is provided with a worm 63, one end of the worm 63 extends outward through one side of the drive box 61, the extended end of the worm 63 is provided with a knob 64, and the worm 63 meshes with the worm gear 62.

[0027] When the circuit board needs to be rotated for uniform cleaning, the operator can manually rotate knob 64. Knob 64 drives the worm gear 63 to rotate. The rotational motion of the worm gear 63 is transmitted to the worm wheel 62 through meshing. The worm wheel 62 rotates accordingly, driving the shaft to rotate. The rotational motion of the shaft drives the rectangular seat 52 and the pressure plate 54 to rotate. Since the pressure plate 54 has already pressed the circuit board firmly, the circuit board will also rotate with the pressure plate 54, so that all parts of the circuit board surface can fully contact the cleaning fluid, achieving uniform cleaning.

[0028] See Figure 3 and Figures 6 to 7As shown, the reciprocating drive component includes a sliding seat 78; the sliding seat 78 is disposed at the bottom of the mounting plate 75, and a circular groove is provided on the sliding seat 78. A drive rod 79 is disposed in the circular groove, and a fixed post 710 is provided at the bottom of the drive rod 79. A second motor 711 is disposed at the top of the mounting plate 75, and the output end of the second motor 711 is connected to the drive rod 79. A sliding plate 712 is slidably disposed in the sliding seat 78, and a rectangular frame 713 is provided at the center of the sliding plate 712. A rectangular through groove for the fixed post 710 to move is provided in the rectangular frame 713. A reciprocating plate 714 is disposed at the bottom of the sliding plate 712, and the bottom of the reciprocating plate 714 is connected to the top of the main flow pipe 76.

[0029] When the circuit board needs to be dried, the second motor 711 is activated. The output of the second motor 711 rotates, driving the drive rod 79 to rotate within the circular groove. The rotational motion of the drive rod 79 is converted into the reciprocating movement of the slide plate 712 through the cooperation of the fixed column 710 and the rectangular frame 713. The slide plate 712 slides back and forth within the sliding seat 78, driving the reciprocating plate 714 and the main flow pipe 76 to move together, thereby ensuring that hot air can evenly cover the surface of the circuit board, achieving uniform drying and improving drying efficiency and quality.

[0030] See Figure 4 and Figure 5 As shown, the thread drive component includes a threaded rod 57, a drive block 58, and a turntable 59; a fixing groove is provided on the placement plate 4, and the threaded rod 57 is disposed in the fixing groove; the drive block 58 is threaded onto the threaded rod 57, and the drive block 58 is connected to the moving plate 51; one end of the threaded rod 57 extends outward through one side of the placement plate 4, and the turntable 59 is disposed on the extended end of the threaded rod 57.

[0031] When the position of the movable plate 51 needs to be adjusted, the turntable 59 is rotated, which drives the threaded rod 57 to rotate. The rotation of the threaded rod 57 drives the drive block 58 to move, which in turn drives the movable plate 51 to move. Thus, the position of the movable plate 51 can be adjusted according to the size of the circuit board.

[0032] See Figure 3As shown, the vertical drive component includes a threaded post 41 and a first motor 43; there are two threaded posts 41, both of which are located inside the cleaning chamber 3; each threaded post 41 is threadedly connected to a threaded sleeve 42, the top of which is connected to the bottom of the placement plate 4; a cavity is provided on the base 1, and the first motor 43 is located inside the cavity. The output end of the first motor 43 is provided with a first rotating rod 44, one end of which is connected to a threaded post 41 on one side. A first synchronous pulley 45 is fitted on the first rotating rod 44. A second rotating rod 46 is located on one side of the first rotating rod 44 inside the cavity. The second rotating rod 46 is connected to a threaded post 41 on the other side. A second synchronous pulley 47 is fitted on the second rotating rod 46. A synchronous belt 48 is fitted on the first synchronous pulley 45 and the second synchronous pulley 47.

[0033] When the vertical position of the placement plate 4 needs to be adjusted, the first motor 43 is started, which drives the first rotating rod 44 to rotate. The first rotating rod 44 drives the first synchronous pulley 45 to rotate. At the same time, the synchronous belt 48 on the first synchronous pulley 45 drives the second synchronous pulley 47 to rotate. The rotation of the second synchronous pulley 47 drives the second rotating rod 46 to rotate. The rotation of the first rotating rod 44 and the second rotating rod 46 drives the threaded posts 41 on both sides to rotate. The rotation of the threaded posts 41 drives the threaded sleeve 42 to move. The threaded sleeve 42 drives the placement plate 4 to move, thereby achieving the adjustment of the position of the placement plate 4.

[0034] See Figure 5 As shown, a limit slider is provided on one side of the pressure plate 54, and a limit groove is provided on the inner wall of the rectangular seat 52 for the limit slider to move.

[0035] When the pressure plate 54 moves, it will drive the limit slider to move within the limit groove, thereby improving the stability of the movement of the pressure plate 54.

[0036] By placing the PCB circuit board on the placement plate 4, the threaded drive component is activated to move the movable plate 51 to a suitable position according to the size of the circuit board. Once the movable plate 51 is in the appropriate position, pulling the handle 55 moves the movable rod 53 and pressure plate 54 upwards, compressing the spring 56 and placing the PCB circuit board into the rectangular base 52. Releasing the handle 55 allows the spring 56 to return to its elastic deformation, causing the pressure plate 54 to fix the PCB circuit board. At this point, the vertical drive component is activated, moving the placement plate 4 into the cleaning chamber 3. The cleaning chamber 3 is filled with cleaning fluid, and the ultrasonic generator 8 is activated. The ultrasonic generator 8 converts the ultrasonic waves into mechanical vibrations through the ultrasonic transducer 9, allowing the cleaning fluid to thoroughly clean the PCB circuit board. At this time, the operator can manually rotate the knob 64. The knob 64 drives the worm gear 63 to rotate. The rotation of the worm gear 63 is transmitted to the worm wheel 62 through meshing. The worm wheel 62 rotates accordingly, driving the rotating shaft to rotate. The rotation of the rotating shaft drives the rectangular base 52 and pressure plate 54 to rotate. Since the pressure plate 54 has pressed the circuit board firmly, the circuit board rotates along with the pressure plate 54, ensuring that all parts of the circuit board surface are fully in contact with the cleaning fluid for uniform cleaning. After cleaning, the vertical drive component returns to its initial state, moving the placement plate 4 upwards. The fan 72 is activated, and after being heated by the heating plate 73, hot air is generated. The hot air is delivered to the circuit board surface through the connecting pipe 74 and the main flow pipe 76 to dry the circuit board. The second motor 711 is activated, and the output end of the second motor 711 rotates, driving the drive rod 79 to rotate within the circular groove. The rotational motion of the drive rod 79 is converted into the reciprocating movement of the slide plate 712 through the cooperation of the fixed column 710 and the rectangular frame 713. The slide plate 712 slides back and forth within the sliding seat 78, driving the reciprocating plate 714 and the main flow pipe 76 to move together, thus ensuring that the hot air can evenly cover the circuit board surface for uniform drying, improving drying efficiency and quality.
