DETAILED DESCRIPTION

[0024] As described in the background technology, in order to further improve the quality of PCB board processing by the device, this embodiment provides a PCB board laser window opening and drilling device, which can quickly position the PCB board on the one hand, and quickly absorb the dust generated in the processing area on the other hand.

[0025] See also Figures 1 to 5 This embodiment proposes a PCB board laser window drilling device, including a workbench 1, and a surrounding frame 2 is fixedly connected to the upper surface of the workbench 1.

[0026] A laser window opening and drilling mechanism 4 is provided inside the surrounding frame 2, and the laser window opening and drilling mechanism 4 includes a first electric slide rail 401 installed on both sides of the surrounding frame 2, and the outer surface of each first electric slide rail 401 is installed with a first electric slider 402 adapted thereto, and a second electric slide rail 403 is provided above the workbench 1, and the top ends of the two first electric sliders 402 are fixedly connected to the bottom surfaces of the second electric slide rails 403.

[0027] The first electric slide rail 401 and the first electric slider 402 are both existing mechanisms and are not within the scope of protection of this application. Therefore, the internal structures and working principles of the first electric slide rail 401 and the first electric slider 402 are not described in detail.

[0028] However, it should be noted that the two first electric slide rails 401 and the two first electric sliders 402 are all controlled by a controller. When the two first electric slide rails 401 are started at the same time, the two first electric sliders 402 will move at the same time, thereby driving the second electric slide rail 403 to move on the Y axis.

[0029] A second electric slider 404 is installed on the inner wall of the second electric slide rail 403. The second electric slider 404 is compatible with the second electric slide rail 403, and the second electric slider 404 and the second electric slide rail 403 are both existing mechanisms. Therefore, the internal structure and working principle of the second electric slider 404 and the second electric slide rail 403 are not described in detail.

[0030] When the second electric slide rail 403 controls the second electric slider 404 to work, the second electric slider 404 can be moved on the X-axis. In this way, in conjunction with the first electric slide rail 401 and the first electric slider 402, the second electric slider 404 can be flexibly moved within the range of the X-axis and the Y-axis, which is beneficial to the subsequent laser window opening and drilling work on the PCB board.

[0031] A positioning mechanism 3 is provided above the workbench 1, and the positioning mechanism 3 includes two marking grooves 301 fixedly connected to the upper surface of the workbench 1, and the inner wall of each marking groove 301 is threadedly connected to a threaded rod 302, and the ends of the two threaded rods 302 close to each other are rotatably sleeved with a positioning plate 303.

[0032] Two limiting rods 304 are fixedly connected to the side surfaces of the two positioning plates 303 that are away from each other. The four limiting rods 304 are slidably connected to the inner walls of the two marking grooves 301 respectively.

[0033] By providing the limiting rod 304 , when the threaded rod 302 rotates, the positioning plate 303 can be moved in the inner wall of the marking groove 301 , so that the PCB board can be positioned at the marking position quickly and conveniently, thereby improving the processing efficiency of the device.

[0034] A handle 305 is fixedly connected to one end of the two threaded rods 302 away from each other, and a limiting plate 306 is fixedly connected to the outer surface of each limiting rod 304 .

[0035] By providing the handle 305 , the contact area of ​​the threaded rod 302 can be increased, making it easier to rotate the threaded rod 302 . By providing the limit piece 306 , the moving track of the positioning plate 303 can be limited to avoid falling off.

[0036] A dust collection mechanism 5 is provided inside the surrounding frame 2, and the dust collection mechanism 5 includes a dust collection box 501 fixedly connected to the inner wall of the surrounding frame 2, an exhaust assembly 502 is installed on the inner wall of the dust collection box 501, the top of the dust collection box 501 is connected to a bellows 505, and the output end of the bellows 505 is connected to a dust collection hood 506.

[0037] When the exhaust assembly 502 is started, the dust below the dust hood 506 can be sucked through the bellows 505 and the dust hood 506 .

[0038] The inner wall of the dust box 501 is fixedly connected with a mounting groove 503 , the inner wall of the mounting groove 503 is installed with a filter plate 504 , and the outer surface of the dust box 501 is installed with a detachable rear cover 509 .

[0039] By providing the filter plate 504, the dust sucked by the dust hood 506 and the bellows 505 can be filtered. By providing the mounting slot 503 and the rear cover 509, the filter plate 504 can be conveniently cleaned or replaced regularly, thereby improving the practicability of the device.

[0040] A bracket 507 is fixedly connected to the outer surface of the surrounding frame 2 , and a guide ring 508 is rotatably connected to the top of the bracket 507 . The output end of the bellows 505 passes through the guide ring 508 and extends to the outside of the guide ring 508 .

[0041] By providing the bracket 507 and the guide ring 508 , the bellows 505 can be suspended in the air. When the dust hood 506 moves, the bracket 507 and the guide ring 508 can enable the bellows 505 to flexibly follow the movement of the dust hood 506 , thereby improving the quality of dust absorption.

[0042] A laser processing head 405 is installed on the outer surface of the second electric slider 404. The laser processing head 405 is an existing mechanism. The internal structure and working principle of the laser processing head 405 are not the objects that need to be protected in this application, so they will not be described in detail.

[0043] The outer surface of the dust hood 506 is fixedly connected to the outer surface of the second electric slider 404 , and the dust hood 506 is located below the laser processing head 405 . The output end of the bellows 505 passes through the second electric slider 404 and is connected to the interior of the dust hood 506 .

[0044] From the above description, it can be seen that the laser processing head 405 and the dust hood 506 are both installed on the second electric slider 404. When the laser processing head 405 processes the PCB board, the dust hood 506 can quickly and accurately absorb the dust in the area where the dust is generated, and the laser processing head 405 and the dust hood 506 can be moved synchronously through the second electric slider 404, which effectively improves the efficiency of the dust hood 506 in absorbing dust, reduces the impact of dust on the PCB board, and improves the processing quality of the device.

[0045] Working principle: When in use, place the PCB board in a marking groove 301, and rotate the handle 305 to move the positioning plate 303, so that the positioning plate 303 can position the PCB board. On the one hand, the stability of the PCB board during processing is improved, and on the other hand, the PCB board can be quickly positioned at the marked position, which is beneficial to the processing of the PCB board. Then drive the first electric slide rail 401, the first electric slider 402, the second electric slide rail 403 and the second electric slider 404 to work, and move the laser processing head 405 to the specified position in turn to perform laser window opening and drilling on the PCB board. At the same time, it is necessary to drive the exhaust component 502 to open. When the exhaust component 502 is turned on, the dust under the dust hood 506 can be sucked in through the bellows 505 and filtered through the filter plate 504. In this way, the laser processing head 405 and the dust hood 506 can be moved synchronously by the second electric slider 404. No matter where the laser processing head 405 is No matter where the work is carried out, the dust hood 506 can quickly absorb the dust generated in the processing area below it, thereby improving the efficiency and quality of dust treatment and reducing the impact of dust on the PCB board. It should be noted that when placing a PCB board in a marking groove 301 for processing, the staff can place another PCB board in another marking groove 301 and position it by turning the corresponding handle 305, and then wait for the laser processing head 405 to complete the processing of the first PCB board. The laser processing head 405 can then process the PCB board that has been positioned on the other side, effectively improving the processing efficiency. After using the device for a long time, the bolts on the surface of the back cover 509 can be unscrewed to disassemble the back cover 509, and then the filter plate 504 can be pulled out from the mounting groove 503, and then the new filter plate 504 can be reinserted into the mounting groove 503, and the back cover 509 can be installed on the surface of the dust box 501 by bolts.
