[0005] The utility model solves the above technical problems with the following technical solutions: a charging head built-in circuit board cleaning structure, comprising:

[0006] One machine;

[0007] A three-axis robotic arm, the three-axis robotic arm is arranged on the machine platform, wherein the three-axis robotic arm includes an x-axis, a y-axis, and a z-axis;

[0008] A glue dispensing machine, which is arranged on the z-axis moving end of the three-axis robot arm and is used for dispensing glue on electronic components on the circuit board;

[0009] The cleaning component includes a negative pressure component for providing negative pressure airflow and a positive pressure component for providing positive pressure airflow. The negative pressure component and the positive pressure component are located on both sides of the dispensing machine and are respectively arranged on the z-axis moving end of the three-axis mechanical arm.

[0010] The beneficial effects of the utility model are:

[0011] 1) The device is equipped with positive pressure components and negative pressure components on both sides of the dispensing machine to provide positive pressure airflow and negative pressure airflow. Before dispensing, the positive pressure component sprays positive pressure airflow to the surface of the circuit board to remove dust and impurities on the surface. At the same time, the negative pressure component provides negative pressure airflow, which can effectively absorb dust or impurities raised by the positive pressure airflow to prevent them from re-attaching to the surface of the circuit board, thereby ensuring the cleaning effect.

[0012] 2) In addition, after dispensing, positive pressure airflow is used to accelerate the air circulation in the dispensing area on the circuit board to promote the drying of the dispensing area. At the same time, the negative pressure component can absorb the odor or toxic odor generated by dispensing to protect the health and safety of the staff. In summary, this cleaning structure can effectively clean the surface of the circuit board, prevent dust and impurities from affecting the dispensing process, improve the quality and efficiency of dispensing, and ensure the quality of the product and the safety of the production environment.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, it also includes a conveying mechanism for conveying the built-in circuit board of the charging head along the direction of the dispensing machine. The conveying mechanism is located below the dispensing machine and is arranged on the top of the machine.

[0015] The beneficial effect of adopting the above further solution is that the circuit boards are conveyed along the direction of the glue dispensing machine by the conveying mechanism, so that the circuit boards can be cleaned in batches before the glue dispensing process.

[0016] Furthermore, a carrying plate is fixedly connected to the z-axis moving end of the three-axis robotic arm, and the glue dispensing machine is fixed on one side of the carrying plate.

[0017] Furthermore, the negative pressure component includes a negative pressure fan and an exhaust pipe, and the positive pressure component includes a blower and an air supply pipe.

[0018] Furthermore, one end of the exhaust pipe is connected to the output end of the negative pressure fan, and one end of the air supply pipe is connected to the output end of the blower.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that a positive pressure airflow is blown into the air supply pipe by a blower, and the air supply pipe discharges the positive pressure airflow toward the circuit board, thereby realizing a blowing action, and further removing dust or impurities on the circuit board. A negative pressure airflow is blown into the exhaust pipe by a negative pressure fan, and the exhaust pipe draws air around the circuit board, which can effectively absorb the dust or impurities raised by the positive pressure airflow and prevent them from re-attaching to the surface of the circuit board.

[0020] Furthermore, the exhaust pipe and the air supply pipe are both made of gooseneck pipes.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that the operating range of the positive pressure airflow and the negative pressure airflow can be controlled through the flexible swinging structure of the gooseneck tube, and by changing the direction and position of the gooseneck tube, the spray direction and range of the airflow can be accurately adjusted so that it covers the specific area that needs to be cleaned or extracted, thereby achieving more precise operation to maximize the cleaning and extraction effects.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] In the circuit board manufacturing process, dispensing is a common process step used to fix electronic components or enhance the protective performance of circuit boards.

[0028] However, there is usually dust and impurities on the surface of the circuit board, which may seriously affect the conductive properties of the circuit board, leading to problems such as poor connection, short circuit or heat, thereby causing the circuit board to fail or perform poorly. The utility model proposes a charging head with a built-in circuit board cleaning structure to solve the above problems.

[0029] The utility model provides the following preferred embodiments

[0030] like Figure 1 and Figure 2 As shown, a charging head built-in circuit board cleaning structure includes:

[0031] One machine 100;

[0032] A three-axis robot arm 200 , which is disposed on the platform 100 , wherein the three-axis robot arm 200 includes an x-axis 201 , a y-axis 202 , and a z-axis 203 ;

[0033] The glue dispensing machine 300 is arranged on the moving end of the z-axis 203 of the three-axis robot 200 and is used for dispensing glue on the electronic components on the circuit board;

[0034] A dust cleaning component 400, the dust cleaning component includes a negative pressure component 410 for providing a negative pressure airflow and a positive pressure component 420 for providing a positive pressure airflow, the negative pressure component 410 and the positive pressure component 420 are located on both sides of the dispensing machine 300, and are respectively arranged on the moving end of the z-axis 203 of the three-axis mechanical arm;

[0035] The device is provided with a positive pressure component 420 and a negative pressure component 410 on both sides of the glue dispenser 300, which are used to provide positive pressure airflow and negative pressure airflow. Before glue dispensing, the positive pressure airflow is sprayed to the surface of the circuit board through the positive pressure component 420 to remove dust and impurities on the surface. At the same time, the negative pressure airflow provided by the negative pressure component 410 can effectively absorb the dust or impurities raised by the positive pressure airflow to prevent them from reattaching to the surface of the circuit board, thereby ensuring the cleaning effect;

[0036] In addition, after glue dispensing, positive pressure airflow is used to accelerate the air circulation in the glue dispensing area on the circuit board to promote the drying of the glue dispensing area. At the same time, the negative pressure component 410 can absorb the odor or toxic odor generated by glue dispensing to protect the health and safety of the staff. In summary, this cleaning structure can effectively clean the surface of the circuit board, prevent dust and impurities from affecting the glue dispensing process, improve the quality and efficiency of glue dispensing, and at the same time ensure the quality of the product and the safety of the production environment.

[0037] In this embodiment, Figure 1 and Figure 2 As shown, it also includes a conveying mechanism 600 for conveying the built-in circuit board of the charging head along the direction of the dispensing machine 300. The conveying mechanism 600 is located below the dispensing machine 300 and is arranged on the top of the machine 100. The conveying mechanism 600 can adopt the common conveying form of conveyor belt in industrial production and manufacturing, which will not be elaborated here. By conveying the circuit board along the direction of the dispensing machine 300 through the conveying mechanism 600, the circuit board can be cleaned in batches before the dispensing process.

[0038] In this embodiment, Figure 1 and Figure 2 As shown, a carrier plate 500 is fixedly connected to the moving end of the z-axis 203 of the three-axis robot 200, and the glue dispensing machine 300 is fixed on one side of the carrier plate 500. The negative pressure component 410 includes a negative pressure fan 411 and an exhaust pipe 412, and the positive pressure component 420 includes a blower 421 and an air supply pipe 422. The negative pressure fan 411 and the blower 421 are located on both sides of the glue dispensing machine 300 and are respectively fixed on the carrier plate 500. One end of the exhaust pipe 412 is connected to the output end of the negative pressure fan 411, and one end of the air supply pipe 422 is connected to the output end of the blower 421.

[0039] A positive pressure airflow is blown into the air supply pipe 422 by the blower 421, and the air supply pipe 422 discharges the positive pressure airflow toward the circuit board to achieve a blowing action, thereby removing dust or impurities on the circuit board. A negative pressure airflow is blown into the exhaust pipe 412 by the negative pressure fan 411, and the exhaust pipe 412 draws air around the circuit board, which can effectively absorb the dust or impurities raised by the positive pressure airflow and prevent them from re-attaching to the surface of the circuit board.

[0040] In this embodiment, Figure 1 and Figure 2 As shown, the exhaust pipe 412 and the air supply pipe 422 are both made of gooseneck tubes. The gooseneck tubes can flexibly swing to control the operating range of the positive pressure airflow and the negative pressure airflow. By changing the direction and position of the gooseneck tubes, the spray direction and range of the airflow can be accurately adjusted to cover specific areas that need to be cleaned or extracted, thereby achieving more precise operation to maximize the cleaning and extraction effects.

[0041] The specific working process of the utility model is as follows:

[0042] (1) Loading

[0043] First, the circuit board to be glued is conveyed along the direction of the glue dispenser 300 by the conveying mechanism 600 .

[0044] (2) Cleaning

[0045] When the circuit board on the conveying mechanism 600 is conveyed to the bottom of the dispensing machine 300, the moving end of the z-axis 203 of the three-axis robot 200 descends and approaches the circuit board. At the same time, the positive pressure airflow is blown into the air supply pipe 422 through the blower 421, and the air supply pipe 422 gushes the positive pressure airflow toward the circuit board to realize the blowing action, thereby removing the dust or impurities on the circuit board. At this moment, the negative pressure fan 411 synchronously blows negative pressure airflow into the exhaust pipe 412, allowing the exhaust pipe 412 to draw air around the circuit board, which can effectively absorb the dust or impurities raised by the positive pressure airflow and prevent them from re-attaching to the surface of the circuit board.

[0046] (3) Dispensing

[0047] After the dust cleaning is completed, the x-axis 201, y-axis 202, and z-axis 203 of the three-axis robot 200 are used to drive the glue dispenser 300 to move in space and move it to the glue dispensing area of ​​the circuit board, and the glue dispenser 300 is used to perform glue dispensing on the glue dispensing area of ​​the circuit board.

[0048] (4) Absorb odor

[0049] When the circuit board is glued, the blower 421 continues to blow positive pressure air into the air supply pipe 422, and the air supply pipe 422 gushes positive pressure air toward the glue dispensing area of ​​the circuit board. The positive pressure air flow is used to accelerate the air circulation in the glue dispensing area on the circuit board to promote the drying of the glue dispensing area. At the same time, the negative pressure fan 411 synchronously blows negative pressure air into the exhaust pipe 412, allowing the exhaust pipe 412 to draw air around the circuit board, which can absorb the odor or toxic odor generated by the glue dispensing and protect the health and safety of the staff.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
