Description

Technical Field

[0001] This utility model relates to the field of circuit board dust removal technology, and in particular to a tornado-type non-contact cleaning device. Background Technology

[0002] SMT (Surface Mount Technology) production lines are highly automated production lines whose core function and purpose is to mount tiny, leadless surface mount components (SMD) onto designated locations on printed circuit boards (PCBs) at high speed and with high precision. After processes such as reflow soldering, they are finally formed into circuit assemblies (PCBAs) that realize specific electronic functions. Dust removal equipment is an important component of SMT production lines.

[0003] When cleaning circuit boards, dust removal is more common on bare PCBs. For PCBA (Printed Circuit Board Assembly) boards with attached components, manual labor is still the primary method. However, manual labor is cumbersome, inconsistent in movements, and cannot guarantee effective dust removal. Furthermore, some dust collectors on the market only offer basic cleaning for bare PCBs, making it difficult to clean PCBs of varying widths. Therefore, this paper proposes a tornado-style non-contact cleaning device. The ventilation system operates by blowing air onto the top surface of the PCB board through multi-channel nozzles. The edge channels of the nozzles then draw in air, creating a high-speed spiral airflow on the PCB surface that sucks up dust, achieving a non-contact dust removal process. Simultaneously, an adjustable conveyor track supports and transports different PCB boards, addressing the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a non-contact cleaning device for tornadoes, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a tornado non-contact cleaning device, including a frame, wherein a first plate, a second plate, a third plate and a fourth plate are sequentially installed inside the frame from bottom to top; The top surfaces of the second and fourth plates are both equipped with horizontal reciprocating drive mechanisms, and the two are placed vertically. The top surface of the third plate is equipped with a stationary plate and a movable plate, and the top surface of the third plate near the end of the movable plate is equipped with a width adjustment mechanism. Eight support wheels are rotatably mounted on the adjacent sides of the stationary plate and the movable plate. A first motor is mounted in the middle of the side away from the stationary plate and the movable plate, and a drive wheel is mounted on the output end of both. A conveyor belt is mounted on the outer wall of the eight support wheels and drive wheels on the same side. The horizontal reciprocating drive mechanism described below has a lower sliding frame in the middle, and a USC dry ultrasonic generator assembly is installed at the top of the lower sliding frame. The middle of its bottom end is connected to an external air source through a pipe. The upper sliding frame is provided in the middle of the horizontal reciprocating drive mechanism described above. The upper sliding frame extends on both sides toward the conveyor belt. A tornado generating component is installed at the bottom of the upper sliding frame. The top surface of the tornado generating component is connected to an external air source and an air pump through pipes.

[0006] Preferably, in any of the above solutions, the frame has a through slot near the middle of the sides of the two conveyor belts for the external PCB board to enter and exit. The four corners of the bottom of the frame are respectively equipped with feet and casters. By using this solution, it is convenient for the operator to enter the PCB board along the through slot to the top of the two conveyor belts. The two first motors are powered on and run to drive the two conveyor belts to rotate synchronously, transporting the PCB board to the area directly below the steel mesh, which facilitates non-contact dust removal operations on the top and bottom of the PCB board later.

[0007] Preferably, in any of the above embodiments, the horizontal reciprocating drive mechanism includes a housing, all four sides of which are bent upwards. First guide rails are mounted on both sides of the inner wall of the housing. A second motor is mounted on one side of the bottom surface of the housing, with a first synchronous pulley mounted at its output end. A second synchronous pulley is rotatably mounted on the side of the housing away from the inner wall of the second motor. A first synchronous belt is mounted between the second synchronous pulley and the first synchronous pulley. The top end of the upper sliding frame is fixedly connected to the first synchronous belt, and the top end of the upper sliding frame is slidably connected to the two first guide rails. This design facilitates the reciprocating sliding of the upper and lower sliding frames along the length of the first guide rails, thereby enabling the respective... The USC dry ultrasonic generator and tornado generator slide back and forth on the upper and lower surfaces of the PCB to ensure uniform dust removal. The entire dust removal process reduces manual intervention and ensures effective dust removal of the PCB. The USC dry ultrasonic generator includes an ultrasonic generator and a transducer. The USC dry ultrasonic generator uses the combined action of high-speed airflow and ultrasonic waves on the bottom surface of the PCB to suspend dirt particles from the PCB. The reflection of the ultrasonic waves carries the particles up and creates a vacuum suction chamber at the suction position, which is used to suck up and separate the dust, ultimately achieving the purpose of cleaning the dust on the bottom surface of the PCB.

[0008] Preferably, in any of the above embodiments, the width adjustment mechanism includes two second guide rails, a third motor, five third synchronous pulleys, four support pulleys, a second synchronous belt, and two lead screws. The third motor is fixedly connected to one side of the third plate. The two second guide rails are fixedly connected to both sides of the top surface of the third plate. The three third synchronous pulleys are fixedly connected to the output end of the third motor and the ends of the two lead screws, respectively. The other two synchronous pulleys and four support pulleys are rotatably connected to one side of the third plate. The second synchronous belt is mounted on the five third synchronous pulleys and four support pulleys. The two lead screws are threaded to both ends of the movable plate. Both ends of the movable plate are bent downwards and slidably connected to the two second guide rails, respectively. This design allows for easy control of the third motor to rotate as needed, driving the two lead screws to rotate synchronously via the second synchronous belt. The two lead screws are threaded to both ends of the movable plate, and the operating principle of the lead screw and nut drive mechanism is used to synchronously drive the two ends of the movable plate to slide along the length of the second guide rail, changing the distance between the two transmission belts. This adapts to PCBs of different widths, thus enabling compatibility with more PCB products and meeting the dust removal needs of PCBs of different widths.

[0009] Preferably, in any of the above solutions, protective frames are installed on both sides of the third plate near the top surface of the frame. The top surface of the protective frame is hollowed out, and a steel mesh is installed in the hollowed-out position. The protective frame spans the stationary plate and the movable plate. By using this solution, it is easy to form a protective structure on the outer wall of the stationary plate and the movable plate. The tornado generating component and the USC dry ultrasonic generating component are powered on and operated, while ensuring that the inflow and outflow air volumes are kept the same, thus avoiding the phenomenon of dust flowing out during the dust removal process.

[0010] Preferably, in any of the above solutions, the top surface of the first plate is equipped with a PLC, a drive power supply, a servo driver, a pneumatic valve, and an electrical switch. In this solution, the inner wall of the frame is equipped with multiple position sensors that sense the position of the PCB board, the upper sliding frame, and the lower sliding frame. All position sensors are electrically connected to the PLC via wires. A touch screen and an audible and visual alarm are installed on one side of the top of the frame. The touch screen and the PLC communicate with each other. The touch screen is used to input parameters, which facilitates the position adjustment of the controlled parts inside the frame and meets the needs of dust cleaning of PCB boards of different sizes. The servo driver is used to drive the first motor, the second motor, and the third motor for precise operation.

[0011] Preferably, in any of the above embodiments, the tornado generating assembly includes two suction frames and three high-speed rotating jet heads. The three high-speed rotating jet heads are located between the two suction frames. This embodiment introduces compressed air into the tornado generating assembly while simultaneously performing an air extraction operation. The compressed air drives the three high-speed rotating jet heads to rotate, thereby causing the airflow to enter the top surface of the PCB board. A high-speed rotating airflow is formed on the top surface of the PCB board, and a low-pressure zone is formed at the center. The contact with the PCB board creates strong vortices and vibrations, which in turn cause dust to flow with the airflow direction, carrying the dust up. As the suction frames draw in air, the dust is simultaneously carried out, thus achieving the purpose of dust removal from the PCB board.

[0012] This utility model has the following advantages: 1. This tornado-style non-contact cleaning device features two horizontal reciprocating drive mechanisms that drive the upper and lower sliding frames in horizontal reciprocating motion. Two conveyor belts are installed, and slots are provided on both sides of the frame to facilitate the placement of PCB boards onto the conveyor belts. The conveyor belts transport the PCB boards directly below the stencil. The upper horizontal reciprocating drive mechanism operates, driving the tornado generator assembly in reciprocating motion. Three high-speed rotating jet nozzles spray air outwards, working in conjunction with the suction operation of the suction frame to create a tornado airflow on the top surface of the PCB board, removing dust. Simultaneously, the lower horizontal reciprocating drive mechanism operates, driving the USC dry ultrasonic generator assembly in horizontal motion. The USC dry ultrasonic generator assembly emits ultrasonic waves towards the bottom surface of the PCB board, causing dust to vibrate and fall. Combined with the blowing and suction operations, the dust is carried out, facilitating dust removal from the PCB board. The overall structure is simple, employing a non-contact dust removal structure that does not contact the product surface, preventing damage to the product surface and minimizing manual intervention to ensure consistent product cleaning quality.

[0013] 2. This tornado-style non-contact cleaning device features a third flat plate on which a stationary plate, a movable plate, and a width adjustment mechanism are mounted. When the third motor is powered on, it drives two lead screws to rotate synchronously via a second synchronous belt. This drives the movable plate to slide along the length of the second guide rail, adjusting the distance between the two conveyor belts. This facilitates the transport of PCBs of different widths, making it compatible with more products and effectively solving the problems existing in the prior art. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0017] like Figures 1 to 11 As shown, a tornado-type non-contact cleaning device includes a frame 1. Inside the frame 1, from bottom to top, a first plate 3, a second plate 4, a third plate 5, and a fourth plate 6 are installed sequentially. Outside the frame 1, an air source (not shown), an air pump (not shown), and a dust collection box are installed, and are connected to the pipes inside the frame 1 through pipes for introducing high-pressure gas and extracting dust.

[0018] The top surfaces of the second plate 4 and the fourth plate 6 are both equipped with horizontal reciprocating drive mechanisms 11, and the two are placed vertically. The top surface of the third plate 5 is equipped with a stationary plate 16 and a movable plate 17. The top surface of the third plate 5 near the end of the movable plate 17 is equipped with a width adjustment mechanism. Eight support wheels 18 are rotatably mounted on the adjacent sides of the stationary plate 16 and the movable plate 17. A first motor 24 is mounted in the middle of the side away from the stationary plate 16 and the movable plate 17, and a drive wheel 15 is mounted on the output end of both. A conveyor belt 19 is mounted on the outer wall of the eight support wheels 18 and the drive wheel 15 on the same side. A lower sliding frame 26 is provided in the middle of the lower horizontal reciprocating drive mechanism 11. A USC dry ultrasonic generator assembly 25 is installed at the top of the lower sliding frame 26, and the middle of its bottom end is connected to an external air source through a pipe. An upper sliding frame 7 is provided in the middle of the upper horizontal reciprocating drive mechanism 11. The upper sliding frame 7 extends on both sides toward the conveyor belt 19. A tornado generating component 9 is installed at the bottom of the upper sliding frame 7. The top surface of the tornado generating component 9 is connected to an external air source and an air pump through pipes.

[0019] The frame 1 has through slots in the middle of the sides near the two conveyor belts 19 for external PCB boards to enter and exit. The four corners of the bottom of the frame 1 are respectively equipped with feet and casters. As an optional technical solution of this utility model, this makes it easy for the operator to put the PCB board into the top position of the two conveyor belts 19 along the through slots. The two first motors 24 are powered on and run, driving the two conveyor belts 19 to rotate synchronously, transporting the PCB board to the bottom of the stencil 12, which facilitates non-contact dust removal operations on the top and bottom of the PCB board later.

[0020] The horizontal reciprocating drive mechanism 11 includes a housing 1101, with all four sides of the housing 1101 bent upwards. First guide rails 1105 are installed on both sides of the inner wall of the housing 1101. A second motor 1103 is installed on one side of the bottom surface of the housing 1101, with a first synchronous pulley 1104 installed at its output end. A second synchronous pulley 1106 is rotatably installed on the side of the housing 1101 away from the inner wall of the second motor 1103. A first synchronous belt 1102 is installed between the second synchronous pulley 1106 and the first synchronous pulley 1104. The top end of the upper sliding frame 7 is fixedly connected to the first synchronous belt 1102, and the top end of the upper sliding frame 7 is slidably connected to the two first guide rails 1105. As an optional technical solution of this utility model, this facilitates driving the upper sliding frame 7 and the lower sliding frame 26 along the first guide rails 1105 respectively. The guide rail 1105 slides back and forth along its length, thereby driving the USC dry ultrasonic generator 25 and the tornado generator 9 to slide back and forth on the upper and lower surfaces of the PCB, ensuring the uniformity of dust removal. The entire dust removal process reduces manual intervention and ensures the dust removal effect on the PCB board. The USC dry ultrasonic generator 25 includes an ultrasonic generator and a transducer. The USC dry ultrasonic generator 25 can use the combined action of high-speed airflow and ultrasonic waves on the bottom surface of the PCB board to suspend the dirt particles from the PCB. The reflection of the ultrasonic waves will carry the particles up and form a vacuum adsorption chamber at the suction position by the air flow on both sides, which is used to suck up and separate the dust, and finally complete the purpose of cleaning the dust on the bottom surface of the PCB board.

[0021] The width adjustment mechanism includes two second guide rails 21, a third motor 23, five third synchronous pulleys 27, four support wheels 18, a second synchronous belt 22, and two lead screws 20. The third motor 23 is fixedly connected to one side of the third plate 5. The two second guide rails 21 are fixedly connected to both sides of the top surface of the third plate 5. The three third synchronous pulleys 27 are fixedly connected to the output end of the third motor 23 and the ends of the two lead screws 20, respectively. The other two synchronous pulleys 27 and the four support wheels 18 are rotatably connected to one side of the third plate 5. The second synchronous belt 22 is mounted on the five third synchronous pulleys 27 and the four support wheels 18. The two lead screws 20 are threadedly connected to both ends of the movable plate 17. Both ends of the movable plate 17 are bent downwards and slidably connected to the two second guide rails 21 respectively. As an optional technical solution of this utility model, this makes it easy to control the third motor 23 to rotate as needed. The second synchronous belt 22 drives the two lead screws 20 to rotate synchronously. The two lead screws 20 are threadedly connected to both ends of the movable plate 17. Then, by utilizing the operating principle of the lead screw and nut drive mechanism, the two ends of the movable plate 17 are synchronously driven to slide along the length direction of the second guide rail 21, changing the distance between the two transmission belts 19, adapting to PCB boards of different widths, thereby being compatible with more PCB board products and meeting the dust removal needs of PCB boards of different widths.

[0022] The third plate 5 is equipped with protective frames 10 on both sides near the top surface of the frame 1. The top surface of the protective frame 10 is hollowed out in the middle, and a steel mesh 12 is installed in the hollowed-out position. The protective frame 10 spans the stationary plate 16 and the movable plate 17. As an optional technical solution of this utility model, this facilitates the formation of a protective structure on the outer wall of the stationary plate 16 and the movable plate 17. The tornado generating component 9 and the USC dry ultrasonic generating component 25 are powered on and operated, while ensuring that the inflow and outflow of air volume are kept the same, so as to avoid the phenomenon of dust flowing out during the dust removal process.

[0023] The top surface of the first plate 9 is equipped with a PLC, a drive power supply, a servo driver, a pneumatic valve, and an electrical switch. As an optional technical solution of this utility model, the inner wall of the frame 1 is equipped with multiple position sensors that sense the position of the PCB board, the upper sliding frame 7, and the lower sliding frame 26. All position sensors are electrically connected to the PLC through wires. A touch screen and an audible and visual alarm are installed on one side of the top of the frame 1. The touch screen and the PLC communicate with each other. The touch screen is used to input parameters, which facilitates the position adjustment of the controlled parts inside the frame 1 and meets the needs of dust cleaning of PCB boards of different sizes. The servo driver is used to drive the first motor 24, the second motor 1103, and the third motor 23 for precise operation.

[0024] The tornado generating assembly 9 includes two air intake frames 13 and three high-speed rotating jet heads 14, with the three high-speed rotating jet heads 14 located between the two air intake frames 13. This is an optional technical solution of the present invention, see reference [link / reference]. Figure 11 As shown, by introducing compressed air into the tornado generating assembly 9 and simultaneously performing an air extraction operation, the compressed air drives the three high-speed rotating jet heads 14 to rotate, thereby causing the airflow to enter the top surface of the PCB board. A high-speed rotating airflow is formed on the top surface of the PCB board, and a low-pressure zone is formed at the center. The contact of the PCB board creates strong vortices and vibrations, which in turn cause dust to flow with the airflow direction, carrying the dust up. As the suction frame 13 draws in air, the dust is carried out simultaneously, thus completing the purpose of dust removal from the PCB board.

[0025] This non-contact tornado cleaning device requires the following steps to use: 1) The PCB board is placed on the two conveyor belts 19 through the through slot. The first motor 24 is powered on and runs, driving the conveyor belts 19 to transport the PCB board directly below the stencil 12. 2) The second motor 1103 in the upper horizontal reciprocating drive mechanism 11 is powered on and rotates in both directions, driving the tornado generating component 9 to reciprocate. The three high-speed rotating jet heads 14 spray air outwards, which, together with the suction operation of the suction frame 13, facilitates the formation of a tornado airflow on the top surface of the PCB board to remove dust. 3) The second motor 1103 in the lower horizontal reciprocating drive mechanism 11 is powered on and runs in both forward and reverse directions, driving the USC dry ultrasonic generator 25 to move horizontally. The USC dry ultrasonic generator 25 emits ultrasonic waves to the bottom surface of the PCB board, causing the dust to vibrate and fall. Simultaneously, it cooperates with the blowing and suction operations to carry the dust out. 4) When the third motor 23 is powered on, it drives the two lead screws 20 to rotate synchronously through the second synchronous belt 22, and drives the movable plate 17 to slide along the length of the second guide rail 21 to adjust the distance between the two conveyor belts 19, so as to facilitate the conveying of PCB boards of different widths.

[0026] In summary, during use, two horizontal reciprocating drive mechanisms 11 are provided to drive the upper sliding frame 7 and the lower sliding frame 26 to perform horizontal reciprocating motion respectively. Two conveyor belts 19 are provided, and through slots are provided on both sides of the frame 1 to facilitate the placement of the PCB board onto the two conveyor belts 19. The conveyor belts 19 transport the PCB board directly below the stencil 12. The upper horizontal reciprocating drive mechanism 11 operates, driving the tornado generator 9 to reciprocate. Three high-speed rotating jet heads 14 spray air outwards, coordinating with the suction operation of the suction frame 13 to form a tornado airflow on the top surface of the PCB board, removing dust. Simultaneously, the lower horizontal reciprocating drive mechanism 11 operates, driving the USC dry ultrasonic generator 25 to move horizontally. Ultrasonic waves are emitted towards the bottom surface of the PCB board, causing dust to vibrate and fall. Simultaneously, blowing and suction operations are used to remove the dust, facilitating dust removal of the PCB board. The overall structure is simple and uses a dust removal structure that does not contact the product surface, ensuring that the dust removal process does not damage the product surface and reduces manual intervention to ensure consistent product cleanliness. A third plate 5 is set up, on which a stationary plate 16, a movable plate 17, and a width adjustment mechanism are installed. When the third motor 23 is powered on, it drives two lead screws 20 to rotate synchronously through the second synchronous belt 22, thereby driving the movable plate 17 to slide along the length of the second guide rail 21 to adjust the distance between the two conveyor belts 19. This facilitates the transport of PCB boards of different widths, is compatible with more products, and effectively solves the problems existing in the prior art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
