Description

Technical Field

[0001] This utility model relates to a water removal device, and more particularly to a water removal device and cleaning equipment for electronic components. Background Technology

[0002] In electronic manufacturing, assembly, or cleaning processes, electronic components typically require dehydration after cleaning or other wet treatments to remove residual water droplets or moisture from their surfaces, ensuring the stability and reliability of subsequent processes (such as adhesive application, assembly, and encapsulation). Currently, the most widely used technology is air blowing dehydration, which involves using a set air source and nozzles to blow compressed air or other gases onto the surface of the electronic components to remove water droplets.

[0003] However, while this method is effective in removing larger water droplets, it is difficult to completely remove tiny water droplets or moisture adhering to the surface of electronic components. These residual tiny water droplets can easily form a water film or moisture layer on the surface. If the moisture is not completely removed during the process of applying adhesive to electronic components, local moisture residue may form in the adhesive. Over time, this moisture can easily cause quality problems such as bulging of the adhesive layer, seriously affecting the sealing and reliability of the product. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a water removal device that can more thoroughly remove water droplets from the surface of electronic components.

[0005] This utility model provides a water removal device for removing water droplets from the surface of electronic components. It includes a base, a driving component disposed on the base, and at least one water removal component. The water removal component includes a cylinder, a dehydration cylinder rotatably disposed in the cylinder, and brush bristles disposed in the dehydration cylinder for brushing away water droplets from the surface of electronic components.

[0006] The dehydration cylinder is used to hold electronic components. The drive assembly is connected to the dehydration cylinder for driving the dehydration cylinder to rotate relative to the cylinder body, so that the bristles rotate around the axis of the cylinder body to brush away water droplets on the surface of the electronic components. The centrifugal force generated by the dehydration cylinder during rotation will discharge the water droplets that fall off the surface of the electronic components.

[0007] In one embodiment, the dehydration cylinder includes a first base and a second base arranged coaxially, and a plurality of support members disposed between the first base and the second base for connecting the two; the bristles are disposed on the support members, and the plurality of support members are spaced apart from each other to form a drainage channel for throwing out water droplets between adjacent support members.

[0008] In one embodiment, the bottom of the cylinder is provided with a plurality of drain outlets for draining water droplets thrown out through the drain channel. The cylinder is configured to block water droplets brushed off from other locations other than the drain outlets and collect them in the bottom area of ​​the cylinder for discharge from the drain outlets.

[0009] In one embodiment, the dewatering device further includes a drain cover disposed on the base. The drain cover includes a housing and a drain pipe disposed on one end of the housing near the base. The housing has at least one mounting part for mounting the dewatering cylinder and at least one drain hole for draining water. The drain hole is connected to the drain pipe and is used to receive water droplets discharged from the drain outlet and discharge them through the drain pipe.

[0010] In one embodiment, the dewatering device further includes an air source and an air blowing pipe connected to the air source, the air blowing pipe being positioned toward the center of the cylinder for blowing off water droplets adhering to the surface of the electronic components.

[0011] In one embodiment, the drive assembly includes a drive motor disposed on the base, at least one drive wheel, and a drive belt, wherein the drive belt is used to drive the drive motor and the at least one drive wheel, and the drive wheel is connected to the dehydration cylinder.

[0012] In one embodiment, the drive assembly further includes a tensioning wheel movably disposed on the base, the tensioning wheel being located between the drive motor and the drive wheel and being connected to the drive belt drive.

[0013] This utility model also provides a cleaning device, including a water removal device according to the above embodiments.

[0014] In one embodiment, the cleaning equipment further includes a gripping device for gripping the electronic component and transporting it into the dehydration drum.

[0015] This invention provides a dehydration device that uses a drive assembly to rotate a dehydration cylinder relative to the cylinder body. During this rotation, the brush bristles rotate around the cylinder's axis, effectively brushing the electronic components inside the cylinder from all angles. This effectively removes water droplets and films adhering to the surface of the electronic components, overcoming the shortcomings of traditional air-blowing dehydration methods in removing fine water droplets and moisture. Simultaneously, the rotation of the dehydration cylinder generates centrifugal force, which quickly dislodges water droplets from the electronic component surface, preventing moisture residue. This structure achieves a synergistic dehydration method combining brushing and centrifugation, resulting in a more thorough and reliable dehydration effect, making it particularly suitable for electronic components with complex or difficult-to-dry surfaces.

[0028] Please refer to Figures 1 to 2 This utility model provides a dehydration device for removing water droplets from the surface of electronic components. The device includes a base 1, a drive assembly 3 mounted on the base 1, and at least one dehydration assembly 2. The dehydration assembly 2 includes a cylinder 21, a dehydration cylinder rotatably disposed within the cylinder 21, and brush bristles 26 disposed within the dehydration cylinder. The dehydration cylinder accommodates the electronic components to be processed, such as aluminum-cased electronic devices, and its axis is coaxial with the axis of the cylinder 21. The brush bristles 26 are arranged circumferentially on the inner wall of the dehydration cylinder and are preferably made of a flexible material, allowing for sufficient contact with the surface of the electronic components while avoiding scratching damage. The drive assembly 3 is connected to the dehydration cylinder and drives the dehydration cylinder to rotate relative to the cylinder 21. When the drive assembly 3 is activated, the dehydration cylinder rotates around its axis, causing the brush bristles 26 to rotate synchronously. The electronic components are placed inside the dehydration drum. During the rotation, the bristles 26 come into contact with the outer surface of the electronic components. Through physical brushing, the water droplets and water film attached to the surface are scraped off, thereby achieving preliminary dehydration.

[0029] Simultaneously, as the dehydration drum rotates at high speed, a significant centrifugal force field is formed inside. Water droplets shed from the surface of the electronic components by brushing are flung out by the centrifugal force, thus achieving further moisture removal. This device combines two dehydration methods, "brushing" and "centrifugal dehydration," significantly improving dehydration efficiency, and is particularly suitable for scenarios where it is difficult to completely remove tiny water droplets and moisture. In practical applications, the dehydration device can be configured with multiple dehydration drums according to the size and shape of the electronic components to achieve parallel dehydration operations and improve the overall processing efficiency of the equipment.

[0030] In this embodiment, the dehydration cylinder includes a first base 22 and a second base 23 coaxially arranged, which respectively constitute the end structure of the dehydration cylinder. Multiple support members 25 are disposed between the first base 22 and the second base 23 to connect them and jointly form a three-dimensional support structure. Brush bristles 26 are mounted on the multiple support members 25 and evenly arranged along the length of the support members 25 to ensure full contact with the outer surface of the electronic components during the rotation of the dehydration cylinder. The multiple support members 25 are spaced apart from each other, forming multiple drainage channels between them. These channels are used to throw water droplets brushed off by the brush bristles 26 into the space of the cylinder body 21 when the centrifugal force is generated during the rotation of the dehydration cylinder, thereby achieving efficient drainage.

[0031] Optionally, the bottom of the cylinder 21 is provided with multiple drain ports 24 for receiving and discharging water droplets thrown out by the drain channel. The cylinder 21, as the outer shell 41 of the dehydration cylinder, not only defines the rotation space but also has guiding and blocking functions, preventing water droplets brushed off from areas outside the drain channel from splashing onto the upper part of the cylinder 21. During rotation, the bristles 26 brush water droplets away from the surface of the electronic components. These droplets are thrown to the inner wall of the cylinder 21 under centrifugal force and converge towards the bottom along the wall of the cylinder 21, finally being discharged through the drain ports 24 at the bottom.

[0032] like Figure 3 As shown, the dewatering device also includes a drain cover 4, which is located below the cylinder 21 and fixedly mounted on the base 1. The drain cover 4 includes an upper housing 41 and a lower drain pipe 44. The housing 41 has a mounting part 42 for mounting the dewatering cylinder and a drain hole 43 for collecting and discharging water droplets. The drain hole 43 communicates with the drain pipe 44 to further guide the water droplets flowing out of the drain port 24 of the cylinder 21 to the outside of the equipment, preventing liquid from accumulating inside the equipment or overflowing.

[0033] When the electronic components to be cleaned are placed in the dehydration drum, the drive assembly 3 starts and drives the dehydration drum to rotate. The brush bristles 26 then rotate around the axis of the dehydration drum, brushing the surface of the electronic components in multiple directions. At the same time, the high-speed rotation of the dehydration drum generates centrifugal force, which throws off the water droplets. The water droplets are first discharged into the drum body 21 through the drainage channel of the dehydration drum, and then collected at the bottom by the guiding structure of the drum body 21. They then flow into the drainage cover 4 through the drain port 24, and finally are discharged through the drain pipe 44, thereby achieving rapid and efficient dehydration of the electronic components.

[0034] In this embodiment, the dehydration device also includes an air source and an air blowing pipe 5 connected to the air source. The air outlet of the air blowing pipe 5 faces the location of the electronic component, and is used to assist in blowing off residual water droplets adhering to the surface of the electronic component during the dehydration process. During the rotation of the dehydration cylinder, the brush bristles 26 physically brush the surface of the electronic component, while the air blowing pipe 5 continuously blows out compressed air. In conjunction with the brushing action, it can perform targeted dehydration on areas with local structural depressions and where the brush bristles 26 cannot fully reach. Especially in the initial stage, the air blowing can help move larger water droplets to areas that are easier to brush; and at the end of the rotation, it can also accelerate the vaporization or desorption of small water droplets, further improving the dehydration efficiency.

[0035] Optionally, the air blowing pipe 5 is a slender tube with its axis roughly coinciding with the axis of the dehydration cylinder, allowing it to be aligned with the central area of ​​the electronic components without interfering with the rotation of the dehydration cylinder. If needed, the air blowing pipe 5 can also be equipped with a regulating valve or pressure regulating device to achieve controllable adjustment of the airflow speed and direction, enhancing the adaptability of water removal.

[0036] like Figure 4 As shown, in this embodiment, the drive assembly 3 includes a drive motor 31, at least one drive wheel 33, and a drive belt 32, preferably a synchronous belt. The drive motor 31 is fixedly mounted on the base 1, and its output shaft is connected to the drive belt 32. The drive belt 32 surrounds at least one drive wheel 33 and is connected to the dewatering cylinder. When the drive motor 31 is working, it drives the drive wheel 33 to rotate through the drive belt 32, thereby causing the dewatering cylinder to rotate at high speed relative to the cylinder body 21, so that the bristles 26 rotate to brush away water droplets from the surface of the electronic components, and at the same time, centrifugal force is generated to throw water away.

[0037] To ensure the tension of the drive belt 32 and prevent slippage or loosening during operation, the drive assembly 3 also includes a tensioning pulley 34. The tensioning pulley 34 is movably mounted on the base 1 and located between the drive motor 31 and the drive wheel 33, contacting and driving the drive belt 32. The tensioning pulley 34 can be adjusted in a specific direction to apply appropriate tension to the drive belt 32, thereby ensuring that the drive belt 32 remains taut throughout long-term operation, improving transmission efficiency and system stability.

[0038] This utility model embodiment also provides a cleaning device including the water removal device described in the above embodiment.

[0039] It is understandable that the dehydration device, as a key component of the cleaning process, works in conjunction with the front-end cleaning module and the rear-end drying or assembly module to form a complete production line. The structural layout of the cleaning equipment can be modularly configured according to production needs to meet the cleaning and dehydration requirements of different types of electronic components.

[0040] In one embodiment, the cleaning equipment further includes a gripping device. The gripping device is positioned between the cleaning zone and the dewatering zone, and can automatically grip the cleaned electronic components according to system control signals, accurately placing them inside the dewatering drum. The gripping device may include a multi-axis robotic arm, a vacuum suction head, or a clamping mechanism, etc., and its motion path and clamping method can be customized according to the shape and positioning method of the electronic components.

[0041] In actual operation, the cleaning equipment washes the surface of electronic components with water using a cleaning mechanism, and then a gripping device transfers them into a dehydration drum for dewatering. After dewatering, the components can be transported to the next workstation for drying or assembly via the same gripping device or production line. The entire process is automated, improving production efficiency, reducing manual intervention, and significantly enhancing the consistency of cleaning quality and dewatering.

[0042] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
