Detailed Implementation

[0027] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings, but this utility model is not limited to the following embodiments.

[0028] In high-end electronics manufacturing, the precision of terminal surface treatment directly affects product quality and performance. Traditional terminal surface treatment methods, such as manual brushing and microscopic inspection, can achieve certain results, but they rely on manual operation, are prone to problems such as missed brushing and missed inspection, and are labor-intensive and inefficient.

[0029] To solve the above problems, this utility model provides a blow-brush-suction device for terminal surface treatment, which is used to automatically brush and clean terminals placed on the material strip assembly 10. The blow-brush-suction device includes: a housing 11 forming an enclosing space, a material strip guide rail 12 passing through the enclosing space, a brush 13 and an electrostatic air gun 14 disposed in the enclosing space, and a negative pressure exhaust pipe 15 for extracting gas inside the enclosing space; the two ends of the material strip guide rail 12 are a near end and a far end, respectively.

[0030] The enclosed space is the space enclosed by the housing 11; the tape assembly 10 can be placed on the tape guide rail 12 and move along the length of the tape guide rail 12; the air outlet of the electrostatic air gun 14 faces the tape guide rail 12; the air inlet of the negative pressure exhaust pipe 15 is located inside the enclosed space to maintain a negative pressure environment in the enclosed space during operation; the tape assembly 10 with terminals installed can be placed on the tape guide rail 12 and move from one side of the tape guide rail 12 to the other side; the brush 13 can clean the surface of the terminals; and the electrostatic air gun 14 can remove static electricity from the terminals and eliminate dust from the surface of the terminals.

[0031] In this embodiment, as Figure 1 , Figure 2 As shown, in the field of electronics manufacturing, terminals are generally connectors used to connect circuits or equipment. To ensure the reliability of terminal connections, the terminal surface needs to be treated, mainly by brushing and electrostatic removal. Currently, these tasks are primarily performed manually.

[0032] This embodiment provides a device capable of performing brushing and static electricity removal operations using automated equipment. The tape assembly 10 is a tooling used to adapt to the shape of terminals and fix their positions. Various shapes and a certain number of terminals can be placed on the tape assembly 10. The shape of the tape assembly 10 matches the shape of the tape guide rail 12; specifically, the width of the tape assembly 10 is not greater than the width of the tape guide rail 12. The tape assembly 10 can be placed on the tape guide rail 12 and can be pushed by a driving device to move on the tape guide rail 12.

[0033] The housing 11 can be a shell formed by splicing together multiple plate-shaped parts to form an internally hollow shell. The space inside the shell is an enclosing space. In this embodiment, the housing 11 is a shell formed by splicing together four flat plates (front side plate, rear side plate, left side plate, and right side plate) and two cover plates (upper cover plate and lower cover plate) through fasteners and connectors.

[0034] As a preferred option, such as Figure 1 , Figure 2 As shown, the housing 11 in this embodiment includes two parts: an upper housing 21 and a lower housing 22. Both the upper housing 21 and the lower housing 22 include a front side plate, a rear side plate, a left side plate, and a right side plate, and the material belt guide rail 12 is disposed between the upper housing 21 and the lower housing 22.

[0035] In some embodiments, such as Figure 3 As shown, the material guide rail 12 includes two guide rail seats 23 and two pressure plates 24. The top of the guide rail seats 23 is provided with a groove. The two guide rail seats 23 are parallel and the grooves of the two guide rail seats 23 are opposite to each other, so that the material belt assembly 10 can be placed in the groove. The two pressure plates 24 are respectively installed above the two guide rail seats 23. The pressure plates 24 are used to press the material belt assembly 10 from above the groove of the guide rail seat 23 to prevent the material belt assembly 10 from tilting up.

[0036] The brush 13 and the electrostatic air gun 14 are arranged on the upper and lower sides of the material belt guide rail 12. The rotating brush 13 can contact the terminals on the material belt assembly 10, and the electrostatic air gun 14 can remove static electricity from the terminals and remove dust from the terminal surface.

[0037] In this embodiment, the negative pressure exhaust pipe 15 is installed on the upper or lower cover plate. The negative pressure exhaust pipe 15 can be connected to a vacuum pump to maintain a negative pressure environment in the enclosed space.

[0038] In a fully enclosed clean environment, the product is precisely secured using a precision guide rail system. Subsequently, a rotating brush 13 is used to meticulously clean the product surface to remove adhering dirt. After cleaning, a plasma electrostatic air gun 14 performs a final dust removal treatment to ensure the product surface meets ultra-clean standards.

[0039] Furthermore, at least two brushes 13 are provided within the enclosed space. The two brushes 13 are respectively located on both sides of the material belt guide rail 12, and the two brushes 13 respectively brush the two surfaces of the terminals on the material belt assembly 10.

[0040] The blowing, brushing, and suction device also includes a driver 25 for driving the brush 13 to rotate, wherein the driver 25 drives the brush 13 to rotate in the opposite direction to the direction in which the material belt assembly 10 moves on the material belt guide rail 12.

[0041] In some embodiments, two brushes 13 are disposed within the enclosing space, with the two brushes 13 respectively disposed on both sides of the feed belt guide rail 12. The driver 25 enables the brushes 13 to rotate actively. The direction in which the driver 25 rotates the brushes 13 is opposite to the direction in which the feed belt assembly 10 moves on the feed belt guide rail 12. Specifically, as shown... Figure 1 or Figure 2 As shown, the tape assembly 10 moves from left to right. The brush 13 at the top of the diagram rotates clockwise, and the brush 13 at the bottom rotates counterclockwise. On the contact surface between the brush 13 and the tape assembly 10, the direction of rotation of the brush 13 is opposite to the direction of movement of the tape assembly 10 on the tape guide 12. The counterclockwise rotating brush 13 can generate greater friction, which is more effective in removing impurities from the terminals.

[0042] Furthermore, four brushes 13 are provided within the enclosed space, with the four brushes 13 arranged in pairs on both sides of the material belt guide rail 12.

[0043] The driver 25 is a motor, and each of the four brushes 13 is connected to a motor. The motor is located outside the housing 11. The motor and the brushes 13 are connected by a rotating shaft, and a bearing is provided at the connection between the housing 11 and the rotating shaft. The motor can drive the rotating shaft to rotate, thereby driving the brushes 13 to rotate.

[0044] In some embodiments, four brushes 13 are arranged within the enclosing space, with two brushes 13 arranged side by side above and below the conveyor belt assembly 10. The conveyor belt assembly 10 passes through one brush 13 first and then another brush 13. This double brushing increases the brushing efficiency and optimizes the brushing effect.

[0045] The driver 25 is an electric motor, and each brush 13 is driven by an independent motor.

[0046] In some embodiments, four motors are respectively arranged on both sides of the housing 11 to facilitate motor maintenance and replacement.

[0047] Furthermore, at least two electrostatic air guns 14 are provided within the enclosed space, respectively located on both sides of the material strip guide rail 12, to remove static electricity and clean the two ends of the terminals respectively;

[0048] The electrostatic air gun 14 is a plasma electrostatic air gun, which can blow out charged air masses to remove the charge on the terminals.

[0049] In this embodiment, two electrostatic air guns 14 are respectively arranged on both sides of the material belt guide rail 12. The electrostatic air gun 14 refers to the air outlet that blows out charged air clouds. The device connected to the air outlet that can generate charged air clouds is not shown in the figure.

[0050] Furthermore, two flow guides 31 are provided within the enclosed space, and the two flow guides 31 are respectively located on both sides of the material belt guide rail 12. The flow guides 31 are trumpet-shaped, including an input end with a large profile and an output end with a small profile. The input ends of the two flow guides 31 face the material belt guide rail 12, and the output ends are connected to the negative pressure exhaust pipe 15.

[0051] In this embodiment, the flow guide 31 is used to connect the negative pressure exhaust pipe 15. The two flow guides 31 in the enclosing space are respectively set above and below the enclosing space, and the pipe of the electrostatic air gun 14 passes through the flow guide 31.

[0052] Furthermore, the material belt assembly 10 is first placed at the near end of the material belt guide rail 12 and then moved to the far end of the material belt guide rail 12;

[0053] Two sealing cylinders 32 are provided on the outside of the housing 11. The two sealing cylinders 32 are respectively located near the far end of the material belt guide rail 12. The two sealing cylinders 32 are respectively connected to sealing elements 33. The sealing cylinders 32 can push the sealing elements 33 closer to the material belt guide rail 12.

[0054] In this embodiment, as Figure 2 , Figure 3 as well as Figure 4 As shown, the housing 11 has two openings at corresponding positions near and far of the material guide rail 12. These openings are used for pulling material onto the material guide rail 12, i.e., placing the material belt assembly 10 onto the material guide rail 12 through the openings in the housing 11. The sealing cylinder 32 and the sealing element 33 are used to retract the sealing cylinder 32 when the material guide rail 12 is pulling material, causing the sealing element 33 to move away from the openings in the housing 11; and to extend the sealing cylinder 32 after the material pulling is complete, causing the sealing element 33 to close the openings in the housing 11. The sealing element 33 can be rubber or a sealing functional component capable of closing the openings in the housing 11.

[0055] Furthermore, a material sensor 34 is provided on the housing 11. The material sensor 34 is used to detect whether a material belt assembly 10 is placed on the material belt guide rail 12. When the material sensor 34 detects the presence of the material belt assembly 10, it can control the brush 13 to start rotating.

[0056] In some embodiments, the material sensor is a diffuse reflection sensor capable of detecting the presence of non-transparent objects. The detection direction of the material sensor is outside the feed direction of the housing, and the detection area of ​​the material sensor is configured to be below the feed belt in the feed direction of the housing when the released feed belt is tightened by a mechanism inside the housing for pulling the feed belt.

[0057] An external feeder is also installed on the outside of the machine casing in the feeding direction. The feeder is used to release the material belt. When the released material belt is tightened by the mechanism inside the machine casing that pulls the material belt, the material sensor cannot detect the material belt, indicating that the material belt is tightened. Conversely, when the material belt released by the feeder is not tightened, the material belt hangs down due to gravity, which is detected by the material sensor. The material sensor outputs a corresponding electrical signal, indicating that the material belt is not tightened.

[0058] Furthermore, the blowing, brushing, and suction device also includes a CCD image sensor 35, which is used to acquire images of the terminal surface. The terminal surface images can be used to detect whether there is dust that has not been removed or areas that have not been thoroughly brushed on the terminal.

[0059] The CCD image sensor 35 is a device that converts light signals into electrical signals. It is widely used in digital imaging technology. Through image recognition technology, it can detect whether there is dust that has not been removed or areas that have not been thoroughly cleaned on the terminals. The efficiency of terminal cleaning can be analyzed through the detection results.

[0060] Furthermore, the blowing, brushing, and suction device includes at least two CCD image sensors 35, which are respectively positioned within the enclosing space near the far end of the material belt guide rail 12; these two CCD image sensors 35 are used to acquire images of both ends of the terminals after cleaning.

[0061] In some embodiments, two CCD image sensors 35 located near the far end of the feed belt guide 12 acquire images of both sides of the terminal after brushing, which can be used to detect the brushing effect and whether there are any missed brushing areas.

[0062] Furthermore, two CCD image sensors 35 are also provided near the end of the feed belt guide 12 within the enclosed space. These two CCD image sensors 35 are used to acquire images of both ends of the cleaning process front end.

[0063] In some embodiments, two CCD image sensors 35 near the near end of the feed belt guide 12 respectively acquire images of both sides of the terminal before brushing. Based on this, the terminal images before brushing can be analyzed, and the brushing parameters, such as the rotation speed of the brush 13 and the speed of the moving feed belt assembly 10, can be adjusted according to this information during brushing.

[0064] In some embodiments, the CCD image sensor may also be located outside the housing, and the terminals are processed by blowing, brushing and suction inside the housing before being processed by the CCD image sensor for image analysis.

[0065] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
