Description

Technical Field

[0001] This invention relates to the field of cleaning device technology, specifically to a coil plate cleaning device. Background Technology

[0002] With technological advancements and societal development, printed circuit boards (PCBs) are increasingly widely used in the electronics industry. Assembled electronic products are becoming more powerful and demanding. PCBs no longer merely serve as supports, interconnectors, and some circuit components in electronic devices; they are increasingly being developed towards lighter, thinner, shorter, smaller, and more multifunctional designs. For example, embedding components like capacitors and resistors within the PCB increases its integration density, and the PCB is required to withstand high current surges. Consequently, coil boards have emerged as a result.

[0003] A coil board is a type of circuit board whose circuit pattern is mainly based on wire winding, with etched circuitry on copper foil replacing traditional copper wire turns. It is primarily used in inductor components and needs to withstand high current surges. Therefore, during the production process of coil boards, it is crucial to prevent cracks from forming between adjacent copper foil layers within the overlap area (including edges) to avoid voltage breakdown and withstand voltage failure caused by cracks.

[0004] The production process of coil boards is subject to contamination to varying degrees at almost every stage, including from micro-particles from cutting, dust, electroplating residues, grease, flux, fingerprints, and sweat. If these residual contaminants are not thoroughly cleaned, they can cause unpredictable damage to the normal operation of the circuit board. Currently, cleaning involves transferring the coil board to a cleaning solution and manually brushing the surface. This method requires a large workforce, is inefficient, and thus affects the normal production of coil boards. Therefore, a device capable of automatically cleaning coil boards is needed to improve production efficiency. Summary of the Invention

[0025] Example 1:

[0026] Please see Figure 1-5 This invention provides a technical solution: a coil board cleaning device, including a cleaning tank 1. A dual-axis motor 19 is fixedly installed at the center of the cleaning tank 1, ensuring that the transmission can move in two directions. A motor shaft 28 is movably installed inside the dual-axis motor 19. A turntable 18 is fixedly installed at the lower end of the motor shaft 28. Rotation of the motor shaft 28 can drive the turntable 18 to rotate. A positioning rod 16 is threadedly engaged on the surface of the turntable 18. A rectangular connecting ring 15 is inserted into the side wall of the positioning rod 16. The rotation of the positioning rod 16 on the surface of the turntable 18 causes the position of the rectangular connecting ring 15 to change. A fixed rectangular connecting ring 15 is fixedly installed on the side wall of the rectangular connecting ring 15. Position rod 4 is movably inserted into the limiting seat 14 welded to the lower surface of the cleaning tank 1. Under the limiting action of the limiting seat 14, the limiting rod 4 can only move horizontally. A rack bracket 5 is fixedly installed at the end of the limiting rod 4. A rack 10 is opened on the surface of the rack bracket 5. At this time, the rack 10 can only perform horizontal reciprocating motion. A gear 30 is meshed on the surface of the rack 10. The movement of the rack 10 will drive the gear 30 to rotate. The central shaft of the gear 30 is movably installed on the gear bracket 9 welded to the upper surface of the cleaning tank 1. A roller 11 is fixedly installed at the center of the gear 30. Several brushes 12 are attached to the side wall of the roller 11. The rotation of the roller 11 drives the brushes 12 to rotate, and finally cleans the surface stains of the coil board.

[0027] A worm gear 20 is fixedly mounted on the upper surface of the motor shaft 28. Rotation of the motor shaft 28 will drive the worm gear 20 to rotate. Two worm wheels 21 are meshed on the side wall of the worm gear 20. The worm gear 20 can transmit the transmission direction to the worm wheels 21. A worm wheel shaft 29 is located at the center of the worm wheel 21 and is located inside the cleaning tank 1. A circular plate 22 is fixedly mounted on the surface of the worm wheel 21. A connecting rod 25 is movably mounted on the side wall of the circular plate 22. The end of the connecting rod 25 is welded to the lower surface of the partition plate 26. Rotation of the circular plate 22 will drive the partition plate connecting rod 25 to move up and down, thereby driving the coil plate above the partition plate 26 to move up and down, changing the cleaning direction of the brush and improving the cleaning effect.

[0028] Please see Figure 1-5In a specific embodiment, a support leg 2 is fixedly installed on the lower surface of the cleaning tank 1, and the support leg 2 has a telescopic rod with height adjustment function. A universal wheel 3 with braking function is fixedly installed on the lower surface of the support leg 2. The support leg 2 provides support for the entire device, and the telescopic function ensures that the device can be used by people of different heights, improving the applicability of the device. The universal wheel 3 facilitates the movement of the device and fixes the entire device in the working position, ensuring its stability. A water outlet pipe 6 is fixedly installed on the lower side wall of the cleaning tank 1. A filter screen is installed inside the water outlet pipe 6, and a valve 7 is fixedly installed on the surface of the water outlet pipe 6. The surface of the valve 7 is covered with a heat insulation sleeve. The wastewater inside the cleaning tank 1 is discharged through the water outlet pipe 6, and the filter screen filters the dirt during the cleaning process, reducing the occurrence of dirt clogging the valve 7. The valve 7 can control the opening and closing of the water outlet pipe 6, and the heat insulation sleeve protects the valve 7.

[0029] Example 2:

[0030] Please see Figure 1-5 In this embodiment, a handle 8 is fixedly provided on the side wall of the cleaning tank 1, and an anti-slip sleeve is fixedly provided on the surface of the handle 8. The handle 8 facilitates the movement of the entire device, and the handle 8 cooperates with the casters 3 to facilitate the movement of the entire device. The anti-slip sleeve increases the friction on the surface of the handle 8, reducing slippage when the operator moves the device. A baffle 17 is fixedly provided at the end of the positioning rod 16. The baffle 17 is circular, and its diameter is larger than the inner diameter of the rectangular connecting ring 15. The baffle 17 fixes the position of the positioning rod 16, and due to the special diameter of the baffle 17, it ensures that the rectangular connecting ring 15 can only move along the positioning rod 16. The baffle 17 limits the position of the rectangular connecting ring 15, reducing the occurrence of derailment.

[0031] Please see Figure 1-5In this embodiment, a cam groove 23 is provided on the surface of the circular plate 22, and a slider 24 is slidably disposed inside the cam groove 23. A connecting rod 25 is fixedly disposed at the end of the slider 24. By providing the slider 24, it can be ensured that the slider 24 slides on the surface of the cam groove 23, and the connecting rod 25 at the end of the slider 24 can move up and down, ultimately causing the partition 26 to move up and down, changing the position of the coil plate. The cleaning box 1 and the partition 26 are provided with guide grooves 13 and positioning grooves 27 that are adapted to the size of the coil plate. The side wall of the partition 26 is slidably connected to the cleaning box 1 through a guide rail. The guide groove 13 limits the movement path of the coil plate, and the positioning groove 27 facilitates the installation of the coil plate. The guide rail is slidably connected to the cleaning box 1, ensuring that the partition 26 can only move vertically, thus ensuring the movement position of the coil plate.

[0032] It should be noted that the present invention is a coil plate cleaning device, and each component is a general standard part or a component known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0033] Working principle: When the device is needed, first place the coil plate to be cleaned into the cleaning tank 1 through the guide groove 13, and place the end of the coil plate into the positioning groove 27. Then start the dual-axis motor 19 of the device. At this time, the dual-axis motor 19 will drive the motor shaft 28 to start rotating. The turntable 18 fixed below the motor shaft 28 will start rotating, causing the position of the positioning rod 16 on the surface of the turntable 18 to change, which in turn causes the rectangular connecting ring 15 on the surface to start moving. Since the limiting rod 4 fixed on the surface of the rectangular connecting ring 15 is fixed by the limiting seat 14, the limiting rod 4 can only reciprocate along the direction of the limiting seat 14. Finally, it drives the rack 10 fixedly connected to the end of the limiting rod 4 to start reciprocating. The reciprocating motion of the rack 10 can drive the meshing gear 30 on the surface to start reciprocating. Finally, it drives the roller 11 fixedly connected to the lower surface of the gear 30 to start rotating. During the rotation, the brush 12 can continuously rub the coil plate to achieve the cleaning purpose.

[0034] After the motor shaft 28 rotates, the worm gear 20 connected above the motor shaft 28 begins to rotate, which in turn drives the worm wheel 21 with surface engagement to rotate. After the worm wheel 21 rotates, the circular plate 22 also begins to rotate, and the position of the cam groove 23 on the surface changes, so that the engagement point of the slider 24 on the surface of the cam groove 23 is different. Ultimately, this can drive the slider 24 to change its height, and the end height of the connecting rod 25 above the slider 24 changes, thus ensuring that the partition 26 can move up and down. At this time, the height of the coil plate fixed above begins to change, thus ensuring that the brush 12 cleans in different places during the cleaning process, increasing the cleaning effect.
