Description

Technical Field

[0001] This application relates to the field of electronic product manufacturing, and more particularly to a dust removal device for printed circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) are a crucial component in the electronics industry. Almost every electronic device, from small items like watches and calculators to large systems like computers, communication devices, and military weaponry, utilizes PCBs to enable electrical interconnection between integrated circuits and other electronic components. A PCB typically consists of an insulating substrate, connecting wires, and solder pads for mounting and soldering electronic components, serving the dual function of conductive lines and an insulating base. It replaces complex wiring, enabling electrical connections between components in a circuit. This simplifies assembly and soldering, reduces the amount of wiring work required by traditional methods, significantly lessening the workload for workers. Furthermore, it reduces the overall size of the device, lowers product costs, and improves the quality and reliability of electronic equipment. PCBs offer excellent product consistency, allowing for standardized designs that facilitate mechanization and automation in production. Moreover, a fully assembled and tested PCB can function as an independent accessory, facilitating interchangeability and maintenance of the entire product. Therefore, PCBs are widely used in the manufacturing of electronic products.

[0003] With the rapid development of the electronics industry, the requirements for PCB manufacturing processes are becoming increasingly stringent. To improve PCB production capacity and reduce production costs, some motherboards are typically produced using multi-panel SMT (Surface Mount Technology) methods. After production, these motherboards need to be cut into smaller panels using a board cutter. Dust residue can remain on the motherboards after this process, leading to defects and affecting product quality. To ensure the quality of circuit layout and electronic component installation on the PCB, dust removal is necessary. However, existing dust removal equipment, designed to meet the requirements of different models, is often bulky and general-purpose, resulting in unsatisfactory overall dust removal performance. Furthermore, the equipment is heavy, difficult to adjust, costly, and energy-intensive. Therefore, addressing these issues and providing a simple, low-cost PCB dust removal device that balances production efficiency and dust removal effectiveness is a crucial consideration for those skilled in the art.

[0056] Typically, with the rapid development of the electronics industry, the process requirements for PCBs are becoming increasingly stringent. To improve PCB production capacity and reduce production costs, some motherboards are often produced using multi-panel SMT (Surface Mount Technology) methods. After production, these multi-panel motherboards need to be cut into individual panels using a board cutter. After separation, dust residue easily remains on the motherboards, causing defects and affecting product quality. To ensure the quality of circuit layout and electronic component installation on the PCB, dust removal is necessary. However, existing dust removal equipment, designed to meet the requirements of different models, is often bulky and general-purpose, resulting in unsatisfactory overall dust removal performance. Furthermore, the equipment is cumbersome, difficult to adjust, costly, and energy-intensive. Therefore, addressing these issues and providing a simple, low-cost PCB dust removal device that balances production efficiency and dust removal effectiveness is a crucial consideration for those skilled in the art.

[0057] Correspondingly, this application provides a printed circuit board (PCB) dust removal device for removing dust from PCBs. The PCB dust removal device includes a chute assembly, a dust removal assembly, and a sensing assembly. The chute assembly has a groove extending along the feeding direction, which guides the PCB to slide along the feeding direction. At least one side of the groove along the feeding direction is an exposed open structure. The dust removal assembly includes a blower blade connected to the chute assembly, with the blower blade's outlet facing the side of the chute assembly. The sensing assembly is spaced apart from the chute assembly and is used to sense whether a PCB is contained within the chute assembly. The sensing assembly is electrically connected to the dust removal assembly and is used to control the dust removal assembly to open or close.

[0058] Furthermore, the chute assembly has a groove extending along the feeding direction. At least one side of the groove along the feeding direction is an exposed open structure, allowing the operator to control the printed circuit board (PCB) to enter or exit the groove along the feeding direction and enabling the PCB to reciprocate along the groove. Simultaneously, a blower blade is connected to the chute assembly with its outlet facing the side of the chute assembly. When the operator controls the PCB to move along the feeding direction, the PCB can move back and forth relative to the blower blade, allowing the airflow from the blower blade to effectively clean dust from the PCB. Moreover, a sensing component can detect whether a PCB is contained in the chute assembly. When the operator controls the PCB to enter the groove, the sensing component generates a signal. The sensing component is electrically connected to the dust removal component and is used to control the dust removal component to turn on. Similarly, when the operator controls the PCB to exit the groove, the sensing component generates another signal, controlling the dust removal component to turn off. It is understood that the PCB dust removal equipment provided in this application embodiment has a simple structure, low cost, and a certain degree of automation, resulting in high efficiency and good dust removal effect.

[0059] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0060] like Figure 1 and Figure 2 As shown, this application embodiment provides a printed circuit board dust removal device 100 for removing dust from printed circuit boards (not shown). The printed circuit board dust removal device 100 includes a housing 11, a dust removal assembly 12, a sliding groove assembly 13, a sensing assembly 14, a dust suction assembly 15, a dust collection assembly 16, and an electrical control box 17. The dust removal assembly 12, the sliding groove assembly 13, the sensing assembly 14, the dust suction assembly 15, and the dust collection assembly 16 are disposed inside the housing 11, and the electrical control box 17 is disposed outside the housing 11; the dust removal assembly 12, the sensing assembly 14, and the dust suction assembly 15 are electrically connected to the electrical control box 17.

[0061] It is understood that the dust removal component 12, the sensing component 14, and the dust collection component 15 can be electrically connected to the electrical control box 17 via wired connection (e.g., wire connection) or via microwave transmission; the electrical control box 17 can be a component that integrates a power supply or power input terminal, integrated control circuit, and other necessary electrical control structures, and has the ability to transmit electrical energy and electrical signals; those skilled in the art will understand that this is achievable, and will not be elaborated here.

[0062] In one embodiment, please refer to Figure 4 and Figure 5 The chute assembly 13 has a groove 1311 extending along the feeding direction X. The groove 1311 is used to guide the printed circuit board to slide along the feeding direction X. At least one side of the groove 1311 along the feeding direction X is an exposed open structure. The dust removal assembly 12 includes a blower blade 121, which is connected to the chute assembly 13. The air outlet 1212 of the blower blade 121 faces the side where the chute assembly 13 is located. The sensing assembly 14 is spaced apart from the chute assembly 13 and is used to sense whether the chute assembly 13 contains a printed circuit board. The sensing assembly 14 is electrically connected to the dust removal assembly 12 and is used to control the dust removal assembly 12 to open or close.

[0063] Understandably, the chute assembly 13 has a groove 1311 extending along the feeding direction X. At least one side of the groove 1311 along the feeding direction X is an exposed open structure, allowing the operator to control the printed circuit board to enter or exit the groove 1311 along the feeding direction X and enable the printed circuit board to reciprocate along the groove 1311. Simultaneously, the air blower 121 is connected to the chute assembly 13, and its air outlet 1212 faces the side where the chute assembly 13 is located. When the operator controls the printed circuit board to move along the feeding direction X, the printed circuit board can move back and forth relative to the air blower 121, allowing the airflow from the air blower 121 to effectively clean the dust on the printed circuit board. Furthermore, the sensing component 14 can sense whether a printed circuit board is contained in the slide assembly 13. When the operator controls the printed circuit board to enter the slide 1311, the sensing component 14 generates a signal. The sensing component 14 is electrically connected to the dust removal component 12 and is used to control the dust removal component 12 to turn on. Similarly, when the operator controls the printed circuit board to exit the slide 1311, the sensing component 14 generates another signal, and the sensing component 14 controls the dust removal component 12 to turn off. It can be understood that the printed circuit board dust removal device 100 provided in this application embodiment has a simple structure and low cost, and at the same time has a certain degree of automation, which makes the dust removal process highly efficient and has a good dust removal effect.

[0064] For ease of understanding, the feeding direction X, air outlet direction Y, and dust suction direction Z are introduced in the embodiments of this application for description. The feeding direction X, air outlet direction Y, and dust suction direction Z are three non-parallel directions in the spatial coordinate system. In subsequent embodiments, the feeding direction X, air outlet direction Y, and dust suction direction Z are described as three mutually perpendicular reference directions in the three-dimensional Cartesian coordinate system. The directions shown in the embodiments of this application are used to help understand the relative positions of the components, but do not limit their specific directions.

[0065] In one embodiment, the housing 11 includes a support 111 and a plurality of cover plates 112. The support 111 forms the supporting skeleton of the housing 11, and the plurality of cover plates 112 are respectively connected to the support 111 and cover the exposed areas around the support 111. The support 111 and the plurality of cover plates 112 cooperate to enclose an internal receiving space 110. The internal receiving space 110 is divided along the suction direction Z into the upper part (along...) Figure 2 The first receiving space 1101 in the vertical direction and the space located below (along the vertical direction) Figure 2 The second accommodating space 1102 (in the vertical direction).

[0066] In this embodiment, the dust removal component 12, the chute component 13 and the sensing component 14 are disposed in the first receiving space 1101, and the dust suction component 15 and the dust collection component 16 are disposed in the second receiving space 1102.

[0067] Understandably, the first containment space 1101 is positioned higher, making it easier for general operators to hold the printed circuit board and reach into it for dust removal; the second containment space 1102 is positioned lower, making it easier for dust to settle naturally under gravity, thus improving dust removal efficiency.

[0068] In this embodiment, the housing 11 also includes a bottom platform 113 and a plurality of rollers 114; the bottom platform 113 is connected to the bracket 111 and located at the bottom of the housing 11 as a support, and the dust collection assembly 16 and the electrical control box 17 are mounted on the bottom platform 113; the plurality of rollers 114 are connected to the bracket 111 and / or the bottom platform 113, and the rollers 114 are configured to be able to rotate and lock, and the plurality of rollers 114 are located at the bottom of the housing 11 for contacting and sliding with the ground or a plane, so that the printed circuit board dust removal equipment 100 can be moved more easily.

[0069] In one embodiment, the housing 11 has a through inlet 1120 along the feeding direction X; at least one side of the tank 1311 along the feeding direction X is exposed through the inlet 1120, and the tank 1311 and the inlet 1120 are connected along the feeding direction X.

[0070] In this embodiment, the cover plate 112 on the front of the printed circuit board dust removal equipment 100 may have a feed inlet 1120; the width of the portion of the feed inlet 1120 corresponding to the slide assembly 13 along the feeding direction X is greater than the width of the slide assembly 13, so that the printed circuit board can pass through smoothly; the upper and lower parts of the feed inlet 1120 have protruding slots, so that the carrier holding the printed circuit board or the operator's hand can pass through.

[0071] Understandably, during the actual cleaning process, the operator can hold the printed circuit board or a carrier that carries the printed circuit board and insert the printed circuit board into the housing 11 through the feed port 1120 to start cleaning. During the cleaning process, the printed circuit board can be driven to move back and forth along the feed direction X until it is clean, and then it is withdrawn through the feed port 1120 to end the cleaning.

[0072] Further integration Figures 3 to 5 As shown, in one embodiment, the tank 1311 has at least two openings 1312; wherein the larger opening 1312 is open along the air outlet direction Y, and the opening 1312 is used for the printed circuit board to be inserted therein and can slide along the feeding direction X; the other smaller opening 1312 is set directly opposite to the feed port 1120 along the feeding direction X and is in communication with the feed port 1120, serving as a channel for feeding or discharging the printed circuit board.

[0073] In one embodiment, the chute assembly 13 includes two chute members 131, which are spaced apart along the air outlet direction Y. Each chute member 131 has a groove 1311, and the opening 1312 side of each groove 1311 faces the other chute member 131.

[0074] In this embodiment, the two sliding chute members 131 are arranged parallel to each other along the feeding direction X, and the two sliding chute members 131 are located at the same height along the dust suction direction Z, and the spatial projections of the two sliding chute members 131 along the air outlet direction Y at least partially overlap. That is, when the printed circuit board is fed along the feeding direction X, the two sides of the printed circuit board along the air outlet direction Y can be respectively engaged with a chute 1311, and can reciprocate horizontally along the feeding direction X, so that the operator can conveniently and quickly control the reciprocating sliding of the printed circuit board to achieve dust removal.

[0075] In other embodiments, the number of chute members 131 may also be multiple, and the multiple chute members 131 are divided into two groups, with each group containing multiple chute members 131 arranged along the feeding direction X. Those skilled in the art will understand that this is certainly achievable.

[0076] In this embodiment, the slide assembly 13 further includes several connecting rods 132. The two slide pieces 131 are respectively connected to the housing 11 through several connecting rods 132. By adjusting the height, spacing and other parameters of the connecting rods 132, the spacing and height of the two slide pieces 131 can be adjusted to adapt to printed circuit boards of different sizes and improve the adaptability of the printed circuit board dust removal equipment 100.

[0077] In one embodiment, the dust removal assembly 12 further includes a plasma wind snake 122, which is connected to a blower blade 121 for cleaning the printed circuit board with a plasma-containing airflow.

[0078] In this embodiment, the plasma wind snake 122 is connected to the cover plate 112 on the top of the housing 11, and the plasma wind snake 122 is connected to the blower blade 121 through a pipe (not shown). At the same time, the plasma wind snake 122 and / or the blower blade 121 are also connected to an airflow generator (not shown). The airflow generator can blow out airflow, and the plasma wind snake 122 can generate plasma. The two work together to make the airflow reaching the blower blade 121 a plasma-containing airflow, which is used to prevent electrostatic discharge and protect the printed circuit board.

[0079] Understandably, the Plasma Wind Serpent 122 is an ion generating unit used to generate a large amount of airflow carrying positive and negative charges to neutralize the charge on the printed circuit board. When the surface of the printed circuit board is negatively charged, it absorbs the positive charge in the airflow, and when the surface of the printed circuit board is positively charged, it absorbs the negative charge in the airflow, thereby neutralizing the static electricity on the surface of the printed circuit board and achieving the purpose of eliminating static electricity. This not only cleans the dust and dirt on the surface of the printed circuit board, but also removes static electricity and prevents static pollution and damage.

[0080] In one embodiment, the air knife 121 extends along the air outlet direction Y and is connected to two sliding groove members 131 respectively. The air outlet 1212 extends along the air outlet direction Y, which intersects with the feeding direction X.

[0081] In this embodiment, the blower blade 121 is generally rectangular in shape. The length direction of the blower blade 121 corresponds to the air outlet direction Y, the width direction corresponds to the feed direction X, and the thickness direction corresponds to the dust suction direction Z. The two ends of the blower blade 121 along the air outlet direction Y are fixedly connected to two sliding groove parts 131 respectively. The upper side of the blower blade 121 along the dust suction direction Z away from the sliding groove parts 131 is provided with an air inlet 1211. The air inlet 1211 can be connected to the plasma wind snake 122 through a connector (not shown) and the pipe. The lower side of the blower blade 121 along the dust suction direction Z towards the sliding groove parts 131 is provided with an air outlet 1212.

[0082] Understandably, the air outlet 1212 can be a long strip extending along the air outlet direction Y (or multiple short strips arranged along the air outlet direction Y). The long strip air outlet 1212 can extend along the air outlet direction Y from one slide member 131 to another slide member 131, so that the airflow blown out of the air outlet 1212 can clean at least one area of ​​the printed circuit board along the air outlet direction Y. At the same time, by controlling the reciprocating motion of the printed circuit board along the feeding direction X, the entire surface of the printed circuit board can be cleaned, thus achieving a better cleaning effect.

[0083] In one embodiment, the sensing component 14 and the slide assembly 13 are located in the same space, and the sensing component 14 is disposed between the two slide members 131 along the air outlet direction Y.

[0084] In this embodiment, the sensing component 14 can be a non-contact sensor such as a distance sensor, photoelectric sensor, or ultrasonic sensor. The sensing component 14 is disposed between the two sliding members 131 along the air outlet direction Y. This area corresponds to the area through which the printed circuit board passes. By placing the sensing component 14 in this area, it can sense whether the printed circuit board is in place.

[0085] In one embodiment, the sensing component 14 and the dust removal component 12 are disposed inside the housing 11, with the sensing component 14 located between the feed inlet 1120 and the blower blade 121 along the feeding direction X.

[0086] Understandably, the sensing component 14 is located at the foremost part of the feed direction X of the printed circuit board or the last part of the discharge direction. It can sense and activate the dust removal component 12 at the first moment when the printed circuit board is being fed, and turn off the dust removal component 12 after the printed circuit board is discharged, making the cleaning process more efficient and the cleaning effect better.

[0087] In one embodiment, the dust suction assembly 15 is spaced apart from the chute assembly 13 and located on the side of the chute assembly 13 opposite to the dust removal assembly 12. The dust suction assembly 15 is configured to generate suction to remove dust.

[0088] In one embodiment, the vacuuming assembly 15 includes a suction member 151 and an isolation member 152. The isolation member 152 is disposed between the suction member 151 and the slide assembly 13. The isolation member 152 has a through hole 1520 for airflow to pass through. The suction member 151 is used to generate suction.

[0089] Understandably, the suction member 151 can be a suction device (e.g., a fan) capable of drawing in and guiding the dust blown up in the first receiving space 1101 to the second receiving space 1102, thereby reducing the dust concentration in the first receiving space 1101 and preventing an explosion. The isolation member 152 can be a partition, which can be connected to the housing 11. The suction member 151 is connected to the housing 11 through the isolation member 152. Dust can pass through the isolation member 152 through the through hole 1520 and be drawn away. At the same time, the partition can block larger objects (e.g., accidentally dropped printed circuit boards or an operator's hand that has been accidentally inserted), preventing damage or injury.

[0090] In one embodiment, the printed circuit board dust removal device 100 further includes a dust collection assembly 16. The dust removal assembly 12, the slide assembly 13, the sensing assembly 14, the suction assembly 15, and the dust collection assembly 16 are configured to be arranged sequentially along the suction direction Z.
