Description

Technical Field

[0001] This utility model relates to the technical field of terminal block processing equipment, and in particular to a cleaning and drying device for terminal block processing. Background Technology

[0002] In the terminal block manufacturing process, the surface of the injection-molded shell is prone to the adhesion of mold release agent, oil stains and operator fingerprints. Dust or slight oxidation layer may also remain in the gaps of the metal terminals. If cleaning is not thorough, it will directly lead to poor contact and reduced electrical performance during subsequent assembly, and even affect the product appearance qualification rate. Therefore, cleaning and drying are key pre-processing steps for terminal block manufacturing. In existing technologies, terminal block cleaning mostly relies on brush-type cleaning devices. These devices achieve cleaning by rotating brushes in conjunction with spraying, but they have insurmountable technical defects, with obvious cleaning blind spots: the brushes are limited by their structure and cannot reach into narrow areas such as wiring holes and metal terminal gaps on the terminal block, resulting in long-term accumulation of oil and residual release agent in these areas. The cleaning rate is less than 60%, which can easily lead to poor terminal contact during subsequent assembly and poor cleaning consistency. The brushes are also prone to local wear during use, resulting in significant differences in cleaning effects within the same batch of terminal blocks. Some areas are over-cleaned while others are under-cleaned, and the product qualification rate can only be maintained at around 80%. In summary, existing brush cleaning devices cannot meet the needs of terminal block processing due to issues such as incomplete cleaning and material damage. There is an urgent need for a targeted cleaning and drying device that can solve the core pain points of unclean brushes and poor ultrasonic compatibility through an ultrasonic cleaning structure combined with a precise transfer and drying mechanism, providing an efficient and low-damage cleaning and drying solution for small-batch terminal block processing.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a cleaning and drying device for processing circuit boards, including an ultrasonic cleaning tank 1, which is a hollow cuboid structure with an open top. A conveyor frame 2 is provided on the right side of the ultrasonic cleaning tank 1. The conveyor frame 2 consists of a support plate, a conveyor belt, and a drive shaft. A drying rack 3 is provided on the conveyor frame 2. The drying rack 3 has a U-shaped structure, and the two inner ends of the drying rack 3 are fixedly connected to the support plate of the conveyor frame 2. After the device is started, the ultrasonic cleaning tank 1 of the single-tank ultrasonic cleaning equipment, model PS-300, is first injected with cleaning fluid suitable for cleaning the terminal block. When the cleaning fluid reaches the preset level, the cleaning transmission mechanism transports the component with the terminal block into the ultrasonic cleaning tank 1. The ultrasonic vibration is used to achieve the initial cleaning of the dirt on the surface and crevices of the terminal block. After cleaning, the cleaning transmission mechanism transfers the terminal block to the conveyor frame 2. The conveyor frame 2 starts and moves the terminal block into the drying rack 3. The drying mechanism on the drying rack 3 then operates to dry the cleaned terminal block. The whole process realizes the initial connection of cleaning, transfer and drying. The ultrasonic cleaning tank 1 provides the cleaning space, the conveyor frame 2 undertakes the transfer function, and the drying rack 3 provides support for the drying process. The three work together to lay the foundation for the cleaning and drying process of the terminal block. Furthermore, the cleaning transmission mechanism includes two gantry frames 4, which are U-shaped structures. The gantry frames 4 are located on the left and right sides of the ultrasonic cleaning tank 1. There are columns 5 at the bottom of both sides of the gantry frames 4, and the columns 5 are hollow cuboid structures. The gantry frame 4 is slidably connected to the inside of the column 5; A slot 6 is provided on the column 5, and a fixing block 7 is fixedly connected to the gantry frame 4. The fixing block 7 is slidably connected inside the slot 6, and a hydraulic cylinder 8 is fixedly connected to the column 5. The output end of the hydraulic cylinder 8 is fixedly connected to the bottom end of the fixed block 7; Two sliding rods 9 and a lead screw 10 are provided between the two gantry frames 4. The two ends of the sliding rods 9 are fixedly connected to the two gantry frames 4, and the two ends of the lead screw 10 are rotatably connected to the two gantry frames 4. A drive motor 11 is fixedly connected to the gantry frame 4 at the position corresponding to the lead screw 10. The output end of the drive motor 11 is fixedly connected to one end of the lead screw 10; When the height of the gantry 4 is adjusted to transfer the wiring board after cleaning, the hydraulic cylinder 8 on the column 5 is activated. The hydraulic cylinder 8 is a miniature tie rod type hydraulic cylinder, model MOB32×100, which consists of a cylinder barrel, piston rod, polyurethane sealing ring, cylinder head and magnetic switch. The output end of the hydraulic cylinder 8 pushes the fixing block 7 to slide along the slot 6 on the column 5. Since the fixing block 7 is fixedly connected to the gantry 4, it drives the gantry 4 to slide up and down inside the hollow column 5, thereby realizing the adjustment of the height of the gantry 4. Then, the drive motor 11 on the gantry 4 starts. The drive motor 11 is a three-phase asynchronous geared motor, model 5IK120RGN-CF, which consists of a motor body, a planetary gear reducer, an output shaft and a junction box. The output end of the drive motor 11 drives the lead screw 10 to rotate. The lead screw 10 cooperates with the subsequent installation components. At the same time, the two slide rods 9 play a guiding role to ensure that the subsequent installation components move stably laterally along the slide rods 9. By adjusting the height and lateral position, the precise transfer of the wiring board above the ultrasonic cleaning tank 1 is guaranteed. The gantry 4 provides support for the overall structure, the column 5 restricts the sliding direction of the gantry 4, the slide rods 9 ensure the stability of movement, and the lead screw 10 and drive motor 11 provide lateral driving force. Furthermore, the ultrasonic cleaning tank 1 has a mounting bracket 12, which is a U-shaped structure. A slider 13 is fixedly connected to the mounting bracket 12 at the position corresponding to the slide rod 9. The slider 13 is slidably connected to the slide rod 9. A moving block 14 is fixedly connected to the center of the mounting bracket 12. The movable block 14 is threadedly connected to the lead screw 10; Electric push rods 15 are fixedly connected to both ends of the inner side of the mounting bracket 12. There is a cleaning basket 16 inside the mounting bracket 12. A tab 17 is provided on the cleaning basket 16 at the position corresponding to the electric push rod 15. The output end of the electric push rod 15 abuts against the tab 17. Driven by the cleaning transmission mechanism, when the lead screw 10 rotates, the moving block 14, which is connected to the lead screw 10, moves accordingly. Since the moving block 14 is fixed at the center of the mounting frame 12, and the mounting frame 12 is slidably connected to the slide rod 9 through the slider 13, the slider 13 slides along the slide rod 9 to provide guidance for the mounting frame 12, thereby driving the mounting frame 12 to move laterally as a whole. When it is necessary to fix or release the cleaning basket 16, the electric push rods 15 at both ends of the inner side of the mounting frame 12 are activated. The electric push rod 15 is a small DC electric push rod, model DT50-100, which includes a motor, trapezoidal lead screw, push rod body, limit switch and aluminum alloy shell. The output end of the electric push rod 15 extends out and abuts against the tab 17 on the cleaning basket 16. The abutting force stabilizes the cleaning basket 16 inside the mounting frame 12, making it convenient to send the cleaning basket 16 and the internal wiring board into the ultrasonic cleaning tank 1 for cleaning. After cleaning, the output end of the electric push rod 15 retracts, releasing the contact of the electrode tab 17, making it easy to transfer the cleaning basket 16 to the conveyor frame 2. The mounting frame 12 provides a mounting carrier for each component, and the cleaning basket 16 is used to place the terminal block. The electric push rod 15 and the electrode tab 17 work together to fix and release the cleaning basket 16, ensuring the stability of the terminal block transfer process. Furthermore, the drying mechanism includes an air pump 18, which is fixedly connected to the drying rack 3, and the output end of the air pump 18 is fixedly connected to an air pipe 19. A nozzle 20 is evenly and fixedly connected to the air pipe 19, and the output end of the nozzle 20 is inserted into the interior of the drying rack 3. When the conveyor 2 transports the cleaning basket 16 containing the cleaned wiring board to the drying rack 3, the air pump 18 on the drying rack 3 is started. The air pump 18 is a miniature high-pressure vortex air pump, model RB-41D-1, which consists of a motor, impeller, air inlet filter, silencer and air outlet. The air pump 18 generates high-pressure airflow and delivers it to the air pipe 19 through the output end. The air pipe 19 evenly distributes the high-pressure airflow to multiple nozzles 20 fixedly connected to it. Since the output end of the nozzle 20 penetrates into the drying rack 3, the high-pressure airflow directly acts on the surface and gaps of the wiring board inside the drying rack 3 through the nozzle 20, quickly blowing away the cleaning liquid remaining on the wiring board. Under the action of airflow, the moisture on the surface of the terminal block evaporates rapidly, achieving a drying effect. The air pump 18 provides airflow power, the air pipe 19 plays the role of airflow delivery and distribution, the nozzle 20 ensures that the airflow is accurately applied to the terminal block, and the drying rack 3 provides a closed space for the drying process, improving drying efficiency and ensuring that there is no residual moisture after the terminal block is dried, thus meeting the needs of subsequent processing.

[0021] Working principle: When the height of the gantry 4 is adjusted to transfer the wiring board after cleaning, the hydraulic cylinder 8 on the column 5 is activated. The hydraulic cylinder 8 is a miniature tie rod type hydraulic cylinder, model MOB32×100, which consists of a cylinder barrel, piston rod, polyurethane sealing ring, cylinder head and magnetic switch. The output end of the hydraulic cylinder 8 pushes the fixing block 7 to slide along the slot 6 on the column 5. Since the fixing block 7 is fixedly connected to the gantry 4, it drives the gantry 4 to slide up and down inside the hollow column 5, thereby realizing the adjustment of the height of the gantry 4. Then, the drive motor 11 on the gantry 4 starts. The drive motor 11 is a three-phase asynchronous geared motor, model 5IK120RGN-CF, which consists of a motor body, a planetary gear reducer, an output shaft and a junction box. The output end of the drive motor 11 drives the lead screw 10 to rotate. The lead screw 10 cooperates with the subsequent installation components. At the same time, the two slide rods 9 play a guiding role to ensure that the subsequent installation components move stably laterally along the slide rods 9. By adjusting the height and lateral position, the precise transfer of the wiring board above the ultrasonic cleaning tank 1 is guaranteed. The gantry 4 provides support for the overall structure, the column 5 restricts the sliding direction of the gantry 4, the slide rods 9 ensure the stability of movement, and the lead screw 10 and drive motor 11 provide lateral driving force. Driven by the cleaning transmission mechanism, when the lead screw 10 rotates, the moving block 14, which is connected to the lead screw 10, moves accordingly. Since the moving block 14 is fixed at the center of the mounting frame 12, and the mounting frame 12 is slidably connected to the slide rod 9 through the slider 13, the slider 13 slides along the slide rod 9 to provide guidance for the mounting frame 12, thereby driving the mounting frame 12 to move laterally as a whole. When it is necessary to fix or release the cleaning basket 16, the electric push rods 15 at both ends of the inner side of the mounting frame 12 are activated. The electric push rod 15 is a small DC electric push rod, model DT50-100, which includes a motor, trapezoidal lead screw, push rod body, limit switch and aluminum alloy shell. The output end of the electric push rod 15 extends out and abuts against the tab 17 on the cleaning basket 16. The abutting force stabilizes the cleaning basket 16 inside the mounting frame 12, making it convenient to send the cleaning basket 16 and the internal wiring board into the ultrasonic cleaning tank 1 for cleaning. After cleaning, the output end of the electric push rod 15 retracts, releasing the contact of the electrode tab 17, making it easy to transfer the cleaning basket 16 to the conveyor frame 2. The mounting frame 12 provides a mounting carrier for each component, and the cleaning basket 16 is used to place the terminal block. The electric push rod 15 and the electrode tab 17 work together to fix and release the cleaning basket 16, ensuring the stability of the terminal block transfer process. When the conveyor 2 transports the cleaning basket 16 containing the cleaned wiring board to the drying rack 3, the air pump 18 on the drying rack 3 is started. The air pump 18 is a miniature high-pressure vortex air pump, model RB-41D-1, which consists of a motor, impeller, air inlet filter, silencer and air outlet. The air pump 18 generates high-pressure airflow and delivers it to the air pipe 19 through the output end. The air pipe 19 evenly distributes the high-pressure airflow to multiple nozzles 20 fixedly connected to it. Since the output end of the nozzle 20 penetrates into the drying rack 3, the high-pressure airflow directly acts on the surface and gaps of the wiring board inside the drying rack 3 through the nozzle 20, quickly blowing away the cleaning liquid remaining on the wiring board.

[0022] Structural Description: Ultrasonic Cleaning Tank 1: The structure is a hollow cuboid with an open top. It is a single-tank ultrasonic cleaning device, model PS-300, used to inject cleaning fluid and accommodate the cleaning of junction boxes. The hollow cuboid structure provides ample cleaning space, suitable for cleaning small batches of junction boxes at the same time. The open top facilitates the conveying of the cleaning basket 16 into and out of the cleaning transmission mechanism. The single-tank design combined with ultrasonic vibration can thoroughly remove dirt from the surface and crevices of the junction boxes, solving the blind spot problem of traditional brush cleaning. The cleaning rate is increased to over 95%, and the model is suitable for small batch processing scenarios, eliminating the need for large-scale equipment redundancy. Gantry 4: The structure is U-shaped and is set on the left and right sides of the ultrasonic cleaning tank 1. It is used to support the slide rod 9, the lead screw 10 and the mounting bracket 12. The U-shaped structure can be straddled above the ultrasonic cleaning tank 1 to provide stable support for the transverse transfer components. The symmetrical distribution on the left and right sides can balance the force on the slide rod 9 and the lead screw 10, avoid structural displacement due to unilateral force, ensure the stability of the cleaning basket 16 during transverse transfer, and adapt to the precise transfer requirements of small batch wiring boards. Column 5: The structure is a hollow cuboid, which is set at the bottom of both sides of the gantry 4. The gantry 4 is slidably connected to the inside of the column 5. The hollow structure can accommodate the bottom of the gantry 4 and restrict the sliding direction of the gantry 4, ensuring that the gantry 4 only moves up and down in the vertical direction, avoiding deviation during the lifting process. Compared with the circular structure, the cuboid structure can further improve the sliding stability, while saving material costs and making the overall structure of the device more compact, suitable for installation space in small workshops. Slot 6: The structure is a long strip-shaped slot opened on the column 5. The fixing block 7 is slidably connected inside the slot 6, providing a clear sliding guide for the fixing block 7. When the fixing block 7 drives the gantry 4 to rise and fall, it moves along the trajectory of the slot 6, avoiding the offset of the fixing block 7 and causing the gantry 4 to tilt during rise and fall. The long strip-shaped structure is adapted to the lifting stroke requirements of the gantry 4, ensuring that the height adjustment range can meet the needs of the cleaning basket 16 entering and exiting the ultrasonic cleaning tank 1, and improving the transfer accuracy. Fixed block 7: The structure is a block-shaped component that is fixedly connected to the gantry 4. It is slidably connected inside the slot 6, and its bottom end is fixedly connected to the output end of the hydraulic cylinder 8. It acts as an intermediate connector and can transmit the driving force of the hydraulic cylinder 8 to the gantry 4, driving the gantry 4 to rise and fall along the column 5. At the same time, by sliding in the slot 6, it ensures that the gantry 4 does not deviate during the power transmission process, ensuring the stability of height adjustment and preventing the wiring board from falling due to unstable lifting. Hydraulic Cylinder 8: This is a miniature tie-rod hydraulic cylinder with a model number MOB32×100. It is fixedly connected to the column 5, and the output end is fixedly connected to the bottom of the fixed block 7. The internal components include a cylinder barrel, piston rod, polyurethane sealing ring, cylinder head, and magnetic switch. The miniature model is suitable for the lifting power requirements of small-batch processing scenarios, avoiding the power redundancy caused by large-size cylinders. The magnetic switch can detect the piston rod stroke in real time to prevent excessive lifting from damaging the gantry 4 or the terminal block. The polyurethane sealing ring improves the cylinder's sealing performance, reduces hydraulic oil leakage, extends the service life of components, and ensures stable lifting power. Slide bar 9: The structure consists of two parallel rod-shaped components, with both ends fixedly connected between the two gantry frames 4. The slider 13 is slidably connected to the slide bar 9, providing double guide support for the lateral movement of the mounting frame 12. Compared with a single slide bar, it can effectively prevent the mounting frame 12 from flipping or shifting during movement. The surface of the slide bar 9 is smooth, which can reduce the frictional resistance when the slider 13 slides, making the movement of the mounting frame 12 more stable and ensuring that the cleaning basket 16 is accurately delivered into the ultrasonic cleaning tank 1 or transferred to the conveyor frame 2. Lead screw 10: The structure is a rod-shaped component set between two gantry frames 4. Both ends are fixedly connected to the gantry frames 4, and one end is fixedly connected to the output end of the drive motor 11. It is connected to the moving block 14 for transmission. It can convert the rotational motion of the drive motor 11 into the lateral linear motion of the mounting frame 12. Through the high precision characteristics of lead screw transmission, the moving distance of the mounting frame 12 can be accurately controlled, which can adapt to the transfer position requirements of different specifications of small batch terminal boards. At the same time, the lead screw transmission has strong stability, which can avoid the mounting frame 12 from jamming during the movement and improve the transfer efficiency. Drive motor 11: A three-phase asynchronous geared motor of model 5IK120RGN-CF, fixedly connected to the gantry 4 at the position corresponding to the lead screw 10. The output end is fixedly connected to one side of the lead screw 10. The internal components include the motor body, planetary gear reducer, output shaft and junction box. The reduction structure can reduce the output speed of the motor, so that the lead screw 10 rotates slowly, ensuring that the lateral movement of the mounting bracket 12 is stable and avoiding the shaking of the terminal block due to excessive movement. The three-phase asynchronous motor has stable power, and the junction box has a built-in overheat protection device to prevent the motor from overheating and being damaged during long-term operation. It is suitable for the intermittent operation requirements of small batch processing and improves the reliability of the device. Mounting bracket 12: The structure is U-shaped and is set above the ultrasonic cleaning tank 1. The slider 13 is fixedly connected to the position corresponding to the sliding rod 9, the moving block 14 is fixedly connected to the center position, and the electric push rod 15 is fixedly connected to both ends of the inner side. The U-shaped structure can cover the cleaning basket 16 from above, which makes it easy for the electric push rod 15 to fix the cleaning basket 16 from both sides. The cooperation of the slider 13 and the moving block 14 allows the mounting bracket 12 to move laterally along the sliding rod 9 to realize the transfer of the cleaning basket 16. At the same time, the U-shaped structure can avoid the ultrasonic cleaning tank 1, avoid interference with the cleaning tank, and ensure the overall structural coordination. Slider 13: The structure is a block-shaped component fixedly connected to the mounting bracket 12 and slidably connected to the slide rod 9, connecting the mounting bracket 12 and the slide rod 9 so that the mounting bracket 12 can slide laterally along the slide rod 9. The slider 13 has a lubrication structure inside, which can reduce friction with the slide rod 9 and improve the smoothness of sliding. At the same time, the block structure of the slider 13 can bear the weight of the mounting bracket 12 and the cleaning basket 16, preventing the mounting bracket 12 from sagging during movement, ensuring the stability of the transfer process, and protecting the terminal block from damage. Moving block 14: The structure is a block-shaped component fixedly connected to the center of the mounting frame 12 and connected to the lead screw 10 for transmission. As a transmission connection between the lead screw 10 and the mounting frame 12, it can convert the rotational movement of the lead screw 10 into the lateral movement of the mounting frame 12. The thread fit between the moving block 14 and the lead screw 10 is highly accurate, which can ensure the precise movement distance of the mounting frame 12 and adapt to the position requirements when transporting small batches of terminal blocks. At the same time, the block structure of the moving block 14 has high strength and can withstand the weight of the mounting frame 12, avoiding deformation during transmission and ensuring transmission stability. Electric push rod 15: This is a small DC electric push rod of model DT50-100, which is fixedly connected to both ends of the inner side of the mounting bracket 12. The output end abuts against the tab 17. The internal components include a motor, a trapezoidal lead screw, a push rod body, a limit switch, and an aluminum alloy shell. The small model is suitable for the inner space of the mounting bracket 12, avoiding excessive space occupation and resulting in a bulky structure. The output end can extend and abut against the tab 17 to fix the cleaning basket 16 through the abutment force, preventing the cleaning basket 16 from shaking during transportation and cleaning. The limit switch can prevent the push rod from extending too far, avoiding squeezing and damaging the cleaning basket 16 or the metal terminals of the terminal block. The aluminum alloy shell is lightweight and corrosion-resistant, extending the service life of the components. Cleaning basket 16: The structure is a basket-shaped component set inside the mounting frame 12. A tab 17 is provided at the position corresponding to the electric push rod 15. It is used to place the terminal block to be cleaned or after cleaning. The basket-shaped structure facilitates the flow of cleaning fluid, ensuring that the cleaning fluid can fully contact the surface and gaps of the terminal block during ultrasonic cleaning, thereby improving the cleaning effect. At the same time, it can place multiple terminal blocks together, which is suitable for small batch cleaning at the same time and improves cleaning efficiency. The tab 17 cooperates with the electric push rod 15 to fix it, preventing the terminal block from falling out of the cleaning basket 16 during transportation and protecting the terminal block from damage. Ear 17: This is a lug-shaped component on the cleaning basket 16 corresponding to the position of the electric push rod 15. It abuts against the output end of the electric push rod 15, providing a clear abutment position for the electric push rod 15. This ensures that the output end of the electric push rod 15 can accurately act on the cleaning basket 16, ensuring uniform fixing force and preventing the cleaning basket 16 from tilting due to uneven force. The lug-shaped structure facilitates quick positioning and abutment after the output end of the electric push rod 15 extends. At the same time, it does not obstruct the loading and unloading of the cleaning basket 16 when the electric push rod 15 is retracted, improving the ease of operation.
