Detailed Implementation

[0025] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-6 A CCD automatic plate inspection machine includes a plate inspection machine body 1, a roller conveyor 2 is provided on one side of the feed port of the plate inspection machine body 1, and a blowing mechanism 3, a brushing mechanism 4 and a dust collection mechanism 5 are provided above the roller conveyor 2.

[0027] The purging mechanism 3 includes a treatment shell 301, with a through groove in the middle of the treatment shell 301 through which the surface of the roller conveyor 2 passes. A first diversion pipe 302 is fixed on the upper part of the inner wall of the treatment shell 301. Multiple nozzles 303 are connected to the bottom of the first diversion pipe 302. A blower 304 is provided on one side of the treatment shell 301. A first conveying pipe 305 is connected to the surface of the blower 304. One end of the first conveying pipe 305 passes through the treatment shell 301 and is connected to the first diversion pipe 302. A cleaning structure is provided on the lower part of the inner wall of the treatment shell 301.

[0028] Through the above technical solution, before the board enters the inspection machine body 1 for inspection, the board is first transported by the roller conveyor 2. The processing shell 301 in the blowing mechanism 3 covers the roller conveyor 2. The blower 304 delivers air to the first diversion pipe 302 through the first conveying pipe 305. The diversion pipe then sprays the air evenly through multiple nozzles 303 to form an airflow to blow the surface of the board, remove impurities, and provide a clean surface for subsequent inspection. The brushing mechanism 4 and the dust collection mechanism 5 work together to further clean the surface of the board, ensuring the accuracy of the inspection. Through multiple cleaning methods of blowing, brushing and dust collection, various impurities on the surface of the board, including dust, fibers, and particles, are effectively removed, thereby ensuring that the CCD optical imaging system can clearly capture the image of the board surface and improve the accuracy of the inspection results. At the same time, this pre-cleaning treatment can also extend the service life of the CCD sensor and reduce equipment failure and maintenance costs caused by the adhesion of impurities.

[0029] The cleaning structure below the inner wall of the treatment shell 301 includes a water supply pipe 306. One end of the water supply pipe 306 is fixedly connected to the lower left side of the inner wall of the treatment shell 301, and the other end of the water supply pipe 306 passes through the treatment shell 301 and is connected to a connector. Multiple water spray nozzles 307 are connected to the surface of the water supply pipe 306. A valve 309 is provided on one side of the treatment shell 301. A water guide plate 308 is fixed at the bottom of the inner wall of the treatment shell 301, and the water supply pipe 306 is located above the water guide plate 308.

[0030] Through the above technical solution, the connector is used to introduce water source, and multiple water spray heads 307 on the water supply pipe 306 can spray water evenly on the surface of the water guide plate 308 to rinse and clean the water guide plate 308, which facilitates the collection and discharge of sewage. This design enables the purging mechanism 3 to add a unified cleaning function for impurities under purging on the basis of airflow purging, further increasing the practicality of the equipment.

[0031] The brushing mechanism 4 includes two first support frames 401. The first support frames 401 are fixed to the top of the roller conveyor 2. A connecting plate 402 is fixed between the two first support frames 401. An electric cylinder 403 is fixed to the top of the connecting plate 402. One end of the electric cylinder 403 passes through the connecting plate 402 and is fixed with a mounting shell 405. A brush plate 404 is detachably connected to the bottom of the mounting shell 405.

[0032] With the above technical solution, when the electric cylinder 403 is working, it drives the mounting shell 405 and the brush plate 404 to move up and down, so that the brush plate 404 contacts the surface of the board and removes the debris from the surface of the board through the brushing action of the brush.

[0033] A T-shaped plate 406 is fixed to the top of the brush plate 404, and the mounting shell 405 is slidably connected to the inner wall of the T-shaped plate 406. The mounting shell 405 has an open structure design on both sides.

[0034] Through the above technical solution, the sliding connection between the T-shaped plate 406 and the mounting shell 405 not only ensures the smooth movement of the brush plate 404, but also facilitates the quick disassembly and replacement of the brush plate 404, reducing the difficulty and time cost of equipment maintenance.

[0035] The dust collection mechanism 5 includes two second support frames 501, which are fixed to the top of the roller conveyor 2. A second diversion pipe 502 is fixed to the bottom of the second support frame 501. Multiple dust collection heads 503 are connected to the bottom of the second diversion pipe 502. An exhaust fan 504 is provided on one side of the roller conveyor 2. A processing box 505 is connected to the surface of the exhaust fan 504. A third diversion pipe 506 is connected to the surface of the processing box 505. One end of the third diversion pipe 506 passes through the second support frame 501 and is connected to the second diversion pipe 502.

[0036] Through the above technical solution, when the exhaust fan 504 is started, a negative pressure is formed at the dust suction head 503, which sucks the dust and debris on the surface of the board into the second diversion pipe 502, and then into the treatment box 505 through the third diversion pipe 506 for processing, thereby achieving dust suction and cleaning of the board surface.

[0037] A square expansion plate 507 is fixed to the inner wall of the treatment box 505. An installation groove is opened on the surface of the square expansion plate 507, and a filter plate 508 is slidably connected to the inner wall of the installation groove.

[0038] Through the above technical solution, when the dust collection mechanism 5 is working, the dust and debris sucked in enter the processing box 505 and are intercepted by the filter plate 508, thereby achieving effective filtration and separation of dust, and the purified air is then discharged through the exhaust fan 504.

[0039] The top of the treatment box 505 has an opening, and a cleaning door 509 is slidably connected to the surface of the opening. The cleaning door 509 has a T-shaped cross-section.

[0040] With the above technical solution, when it is necessary to clean or replace the filter plate 508 inside the processing box 505, the cleaning door 509 can be slid open to facilitate the upward removal of the filter plate 508.

[0041] Both the cleaning door 509 and the treatment box 505 have multiple threaded holes 510 on their surfaces.

[0042] Using the above technical solution, the cleaning door 509 can be unlocked by loosening the bolt in the threaded hole 510.

[0043] Two guide rods 407 slide through the surface of the connecting plate 402, and the bottom of the guide rods 407 are fixedly connected to the top of the mounting shell 405.

[0044] Through the above technical solution, the guide rod 407 ensures the stability and straightness of the mounting shell 405 during movement, and ensures that the brush plate 404 can evenly brush the surface of the plate.

[0045] The water guide plate 308 is designed with an inclined structure that is higher on the left and lower on the right.

[0046] Through the above technical solution, the water guide plate 308 at the bottom of the inner wall of the treatment shell 301 has an inclined structure with the left side higher than the right side, which helps to guide the flushed sewage to one side of the treatment shell 301.

[0047] Working principle: The board material is conveyed to the inspection machine body 1 via roller conveyor 2. During this process, the blowing mechanism 3 is activated, and the blower 304 delivers air through the first conveying pipe 305 to the first diversion pipe 302. Then, multiple nozzles 303 evenly spray airflow to initially blow away larger particles of debris from the board surface. At the same time, the brushing mechanism 4, driven by the electric cylinder 403, moves the brush plate 404 to contact the board surface, removing stubborn stains and small debris through brushing. The vacuuming mechanism 5 works simultaneously, and the exhaust fan 504 generates negative pressure to remove dust through suction. Dust collector 503 picks up dust and particles from the surface of the board. The dust enters the processing chamber 505 through the third diversion pipe 506, where it is filtered and separated by the filter plate 508. The purified air is then discharged. After this series of cleaning processes, the impurities on the surface of the board are thoroughly removed, ensuring that the CCD optical imaging system can acquire clear and accurate images, thereby achieving precise detection of the front and back of the board and other quality features. The entire process is highly automated, with each mechanism working together to effectively improve detection efficiency and accuracy, while reducing manual intervention and maintenance costs.
