[0027] Please refer to the following: Figs. 1 to 3 This utility model discloses a dust-free CNC milling precision machining device for board edges, comprising: a support frame 1, a fixture base 2, a dust collection drawer 3, a movable cover plate 4, and several automatic locking mechanisms 5; the fixture base 2 is mounted on the support frame 1, and at least one dust collection drawer 3 is movably mounted on the side of the fixture base 2; the movable cover plate 4 is movably connected to the fixture base 2, and several automatic locking mechanisms 5 are evenly distributed on the side of the fixture base 2, each automatic locking mechanism 5 being connected to the support frame 1, and each automatic locking mechanism 5 being movably locked to the movable cover plate 4.

[0028] Specifically, when the dust-free CNC milling precision machining device of this utility model is in operation, the operator first opens the movable cover plate 4 and places the PCB material to be processed on the fixture base 2. After the fixture base 2 completes the positioning, the movable cover plate 4 is re-aligned and placed on the PCB to be processed. Next, the user controls the automatic locking mechanism 5 to lock the movable cover plate 4 onto the fixture base 2, preventing PCB displacement during processing. Furthermore, the surface of the fixture base 2 is provided with several integrated perforations, allowing the surface to connect to the receiving cavity of the dust collection drawer 3. Thus, when the support frame 1 is placed on an external CNC router for router processing, the router cutter passes through the pre-reserved processing position on the movable cover plate 4 to process the PCB. Subsequently, the dust generated during router processing is contained beneath the movable cover plate 4, and the cutting debris generated after router processing can fall from the fixture base 2 into the dust collection drawer 3. After completing a set of PCB processing steps, the operator pulls the dust collection drawer 3 out from the side of the fixture base 2, cleans the dust to a preset position, and then places it back into the fixture base 2. Therefore, it can be seen that the dust-free CNC router precision machining device of this utility model can block the dust generated during processing through the movable cover plate 4; and allow the dust generated during processing to fall from the fixture base 2 and be collected uniformly by the dust collection drawer 3. Thus, it can be said that the dust-free CNC router precision machining device of this utility model solves the technical problem of how to reduce the large amount of dust generated during PCB board processing.

[0029] Furthermore, each of the automatic locking mechanisms 5 is provided with a locking drive cylinder 501, a telescopic piston rod 502, a locking bracket 503, a rotating shaft 504, and a T-shaped swing arm structure 505; the locking drive cylinder 501 is disposed in the support frame 1, the telescopic piston rod 502 is movably inserted in the support frame 1, and the locking drive cylinder 501 is drivenly connected to the telescopic piston rod 502; the locking bracket 503 is disposed on the side of the fixture base 2, the rotating shaft 504 is movably disposed on the locking bracket 503, the lower end of the T-shaped swing arm structure 505 is connected to the rotating shaft 504, and the T-shaped swing arm structure 505 connects the telescopic piston rod 502 and the movable cover plate 4 respectively.

[0030] Specifically, the overall shape of the T-shaped swing arm structure 505 resembles the Chinese character "ding" (T-shaped); it is provided with an end rod portion 505a, a first connecting portion 505b, a second connecting portion 505c, and a fastening portion 505d; the lower end of the end rod portion 505a is connected to the rotating shaft 504, the first connecting portion 505b and the second connecting portion 505c are arranged adjacent to each other, up and down, on the side of the end rod portion 505a, the first connecting portion 505b is movably connected to the upper end portion of the telescopic piston rod 502, and the second connecting portion 505c is movably connected to the middle portion of the telescopic piston rod 502; the fastening portion 505d is arranged on the upper portion of the end rod portion 505a, and the fastening portion 505d is movably connected to the movable cover plate 4.

[0031] More specifically, the locking drive cylinder 501 can drive the telescopic piston rod 502 to extend or shorten. Thus, when it is necessary to lock the movable cover plate 4 onto the jig base 2, the telescopic piston rod 502 extends to push the first connecting portion 505b, so that the end rod portion 505a swings around the rotating shaft 504, causing the fastening portion 505d to act to fit onto the movable cover plate 4; when it is necessary to unlock the movable cover plate 4 from the jig base 2, the locking drive cylinder 501 drives the telescopic piston rod 502 to retract, so that the telescopic piston rod 502带动 the second connecting portion 505c, causing the end rod portion 505a to act again around the rotating shaft 504 in the opposite direction to the previous locking, and further, causing the fastening portion 505d to release the abutting connection to the movable cover plate 4.

[0032] Furthermore, the jig base 2 is provided with a base body 201, a dust collection cavity 202, a hollow structure 203, PCB positioning posts 204, and cover plate positioning posts 205; the dust collection cavity 202 is arranged under the base body 201, and the dust collection drawer 3 is movably connected to the dust collection cavity 202; the hollow structure 203 is arranged above the base body 201, and the hollow structure 203 is communicated with the dust collection cavity 202; several PCB positioning posts 204 are evenly distributed on the base body 201, several cover plate positioning posts 205 are evenly distributed on the base body 201, and each cover plate positioning post 205 is respectively movably connected to the movable cover plate 4.

[0033] Furthermore, the movable cover plate 4 has a cover plate main body 401, a machining avoidance structure 402, and several limit connection holes 403; several machining avoidance structures 402 are evenly arranged in the cover plate main body 401, several limit connection holes 403 are evenly distributed on the periphery of the cover plate main body 401, and each limit connection hole 403 is correspondingly movably connected to a cover plate positioning post 205.

[0034] Specifically, the PCB positioning body 204 provided on the base 201 can pre-limit the PCB when the operator places it, ensuring that the PCB to be processed is positioned at a preset processing location. The processing avoidance structure 402 is a perforated window structure, allowing the router cutter to pass through the cover body 401 to process the PCB placed on the base 201 when the CNC router is processing the PCB. During processing, the generated dust can enter the dust collection chamber 202 through the perforated structure 203 and be collected by the dust collection drawer 3.

[0035] In summary, the present invention provides a dust-free CNC milling precision machining device for plate edges, comprising a support frame 1, a fixture base 2, a dust collection drawer 3, a movable cover plate 4, and several automatic locking mechanisms 5. The fixture base 2 is mounted on the support frame 1, and at least one dust collection drawer 3 is movably mounted on the side of the fixture base 2. The movable cover plate 4 is movably connected to the fixture base 2. Several automatic locking mechanisms 5 are evenly distributed on the side of the fixture base 2, each automatic locking mechanism 5 being connected to the support frame 1 and movably locking the movable cover plate 4. During operation, the dust-free CNC milling precision machining device can shield the dust generated during machining through the movable cover plate 4, allowing the dust to fall from the fixture base 2 and be collected uniformly by the dust collection drawer 3. Therefore, it can be said that the present invention, a dust-free CNC milling machine for precision machining of PCB boards, solves the technical problem of how to reduce the large amount of dust generated during PCB board processing.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
