Description

Technical Field

[0001] This utility model relates to the field of SMT (Surface Mount Technology) soldering and cleaning technology, specifically to an SMT soldering and cleaning device. Background Technology

[0002] SMT (Surface Mount Technology) soldering cleaning technology is a key step in ensuring PCBA (Printed Circuit Board Assembly) reliability. It is mainly used to remove contaminants such as residual flux, oil, and metal oxides from the soldering process. Dry ice cleaning technology is a highly efficient and environmentally friendly SMT surface cleaning solution. Its core principle is based on the physical properties and impact effect of solid carbon dioxide particles. It removes contaminants through multi-dimensional action. Dry ice cleaning uses solid carbon dioxide particles at -78.5℃, driven by compressed air, to impact the target surface at high speed. The low temperature causes contaminants such as flux and oil to quickly condense and become brittle. At the same time, the dry ice particles sublimate and expand in volume upon contact, generating an explosive effect to peel off the contaminants. It can reach deep into areas that are difficult to reach by traditional methods, such as the bottom of components and the gaps between dense solder joints.

[0003] In the existing technology, the cleaning of SMT components with dry ice generally relies on manual operation of the handheld nozzle. The difference in the skill level of different operators leads to unstable cleaning results. Continuous handheld spray gun operation can easily cause muscle fatigue, further reducing the cleaning area per unit time. Therefore, we need an SMT component soldering cleaning device.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0023] This utility model provides an SMT (Surface Mount Technology) soldering cleaning device, such as... Figures 1-4As shown, the device includes a frame 1, a belt conveyor 2 on top of the frame 1, a positioning component 3 on top of the belt conveyor 2, a patch body 4 engaged with the top of the positioning component 3, and an adjustment component 5 on top of the belt conveyor 2. The adjustment component 5 includes a cleaning tank 501, an electric slide rail 502 fixedly connected inside the cleaning tank 501, a slide rail sleeve 503 slidably connected to the outer wall of the electric slide rail 502, and a bracket 504 fixedly connected to the bottom of the slide rail sleeve 503. The electric slide rail 502 forms a sliding structure with the slide rail sleeve 503 and the bracket 504, and the outer wall of the electric slide rail 502 is fitted against the inner wall of the slide rail sleeve 503 to enhance stability. The connection between the electric slide rail 502 and the slide rail sleeve 503 is improved, allowing the slide rail sleeve 503 to slide along the inside of the slide rail sleeve 503 by means of the electric slide rail 502. A motor 505 is fixedly connected to one side of the bracket 504, and a first gear 506 is fixedly connected to the output end of the motor 505. A second gear 507 is meshed with the outer wall of the first gear 506. The motor 505 forms a meshing transmission structure through the first gear 506 and the second gear 507. The size of the first gear 506 is smaller than the size of the second gear 507, which strengthens the connection between the motor 505 and the first gear 506, allowing the motor 505 to drive the first gear 506. This drives the second gear 507 to rotate. A crank 508 is fixedly connected to one side of the second gear 507. An adjusting rod 509 is movably connected to one end of the crank 508. A movable frame 510 is movably connected to one end of the adjusting rod 509. A nozzle 511 is fixedly connected inside the movable frame 510. The crank 508 and the movable frame 510 form a swing structure through the adjusting rod 509. The adjusting rod 509 is positioned between the crank 508 and the movable frame 510, strengthening the connection between the crank 508 and the adjusting rod 509. This allows the crank 508 to drive the adjusting rod 509 to pull the movable frame 510 back and forth when it rotates, thereby controlling the nozzle 511. The purpose of adjusting the tilt angle is achieved by using a belt conveyor 2 to transport the patch body 4 into the cleaning tank 501, and by connecting an external dry ice cleaner to the nozzle 511. The nozzle 511 can clean the patch body 4. At the same time, the motor 505 is started, which drives the second gear 507 to rotate via the first gear 506. The second gear 507 can drive the crank 508 to rotate, which can drive the adjusting rod 509 to pull the movable frame 510 to move. This can then drive the nozzle 511 to adjust to different tilt angles, so as to meet the need for cleaning different positions of the patch body 4.

[0024] In a further preferred embodiment of this utility model, such as Figure 1-4As shown, the positioning component 3 includes a placement box 301. A guide rod 302 is fixedly connected inside the placement box 301. A sliding sleeve 303 is slidably connected to the outer wall of the guide rod 302. The placement box 301 forms a sliding structure with the guide rod 302 and the sliding sleeve 303. The outer wall of the guide rod 302 is fitted against the inner wall of the sliding sleeve 303, strengthening the connection between the sliding sleeve 303 and the guide rod 302, allowing the sliding sleeve 303 to slide along the outer wall of the guide rod 302. A spring 304 is fixedly connected to one side of the sliding sleeve 303. The sliding sleeve 303 and the placement box 301 form an elastic structure with the spring 304. One end of the spring 304 is fixedly connected to one side of the sliding sleeve 303, and the other end of the spring 304 is fixedly connected to the inner wall of the placement box 301, strengthening the connection between the sliding sleeve 303 and the spring 304, allowing the placement box 301 to slide along the outer wall of the guide rod 302. The sliding sleeve 303 is supported by a support. A connecting rod 305 is movably connected to the top of the sliding sleeve 303. A movable plate 306 is movably connected to one end of the connecting rod 305. A column 307 is fixedly connected to one side of the sliding sleeve 303. A clamping plate 308 is fixedly connected to one end of the column 307. By pressing down on the movable plate 306 on the placement box 301, the movable plate 306 can be moved downward and push the connecting rod 305. This allows the connecting rod 305 to push the sliding sleeve 303 to slide along the outer wall of the guide rod 302 and compress the spring 304. At this time, the clamping plate 308 on the column 307 can be unfolded and the patch body can be placed between the clamping plates 308. When the pressure on the movable plate 306 is released, the spring 304 rebounds and pushes the sliding sleeve 303 to move, which can drive the clamping plate 308 to position and clamp the patch body 4.

[0025] Working principle: During use, pressing down on the movable plate 306 on the placement box 301 moves the movable plate 306 downwards, pushing the connecting rod 305. This causes the connecting rod 305 to push the sliding sleeve 303 along the outer wall of the guide rod 302, compressing the spring 304. This unfolds the clamping plate 308 on the column 307, allowing the patch body 4 to be placed between the clamping plates 308. When the pressure on the movable plate 306 is released, the spring 304 rebounds, pushing the sliding sleeve 303 to move, which in turn causes the clamping plates 308 to position and clamp the patch body 4. Additionally, the installation... Then, the patch body 4 can be transported to the cleaning tank 501 by the belt conveyor 2, and the external dry ice cleaner is connected to the nozzle 511. The patch body 4 can be cleaned by the nozzle 511. At the same time, the motor 505 is started, which drives the second gear 507 to rotate by the first gear 506. The second gear 507 drives the crank 508 to rotate, which drives the adjusting rod 509 to pull the movable frame 510 to move. This allows the nozzle 511 to be adjusted to different tilt angles, so as to meet the needs of cleaning different positions of the patch body 4.
