[0004] Although the above patent utilizes the conical filter holes on the filter plate so that when the dust passes through the filter plate, larger dust impurities can be stuck in the filter holes, thereby blocking larger impurities and ensuring the normal use of the device, from a practical point of view, the cleaning of impurities mainly relies on the suction of the exhaust fan. Once the laser drilling is completed and the exhaust fan is turned off, larger impurities tend to lose their continuous attraction in the conical filter holes and then fall to the bottom plate under gravity, thereby reducing the collection effect of larger impurities.

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Example 1

[0024] Reference Figure 1-4 As shown, an IC carrier drilling device comprises a bottom plate 1, a shroud 3 arranged above the bottom plate 1, a filter plate 5 detachably arranged inside the shroud 3, and a fan 4 connected and installed on the top of the shroud 3, support plates 2 are fixed between the bottom plate 1 and both sides of the bottom surface of the shroud 3, a laser drilling assembly (not shown) is arranged between the two support plates 2, and a plurality of cone-shaped filter holes are opened at equal intervals on the inner wall of the filter plate 5;

[0025] After the IC carrier is laser drilled between the two support plates 2 by the laser drilling assembly, the dust remaining on the laser drilling assembly is discharged through the fan 4. When the dust passes through the filter plate 5, the larger dust impurities are stuck in the cone-shaped filter holes, while the fine dust is discharged outward by the fan 4, which is conducive to blocking larger impurities, ensuring the normal use of the device, and also facilitating the subsequent cleaning;

[0026] In addition, referring to a PCB board laser drilling and cutting device with prior art patent announcement number CN219852680U, the above document clearly discloses the base plate 1, support plate 2, air guide cover 3, fan 4, filter plate 5, filter hole and laser drilling assembly. This method only roughly describes the connection relationship and use effect between the various components. In particular, the technical features of the laser drilling assembly are already well known to the public. This scheme does not go into too much description of its principle and structure. For details, please refer to the above-mentioned documents.

[0027] Further, refer to Figure 2 As shown, it is worth noting that one end of the filter plate 5 passes through the air guide cover 3 and is fixed with a pull plate 6, and both ends of the pull plate 6 are detachably connected to the side wall of the air guide cover 3 by bolts;

[0028] After the dust on the laser drilling assembly is cleaned, it is only necessary to loosen the bolts at both ends of the pull plate 6 in advance to release the fixing effect between the pull plate 6 and the air deflector 3, and then pull the pull plate 6 to pull the filter plate 5 out from the inside of the air deflector 3, and then the filter plate 5 can be replaced and cleaned.

[0029] However, from a practical point of view, the impurity cleaning in the above embodiment mainly relies on the suction of the fan 4. Once the laser drilling is completed and the fan 4 is turned off, the larger impurities tend to lose their continuous attraction in the conical filter holes and then fall onto the bottom plate 1 under gravity, thereby reducing the collection effect of the larger impurities.

[0030] Further, refer to Figure 3 As shown, it is worth noting that it also includes a blocking mechanism for preventing impurities from falling;

[0031] The blocking mechanism includes two blocking plates 7 respectively arranged on both sides of the air deflector 3. A transmission component for driving the two blocking plates 7 to slide synchronously in opposite directions is arranged on the outer side of the air deflector 3. One end of the blocking plate 7 penetrates into the air deflector 3 and fits against the bottom surface of the filter plate 5. A movable plate 8 is fixed to the other end of the blocking plate 7.

[0032] By setting the blocking mechanism, when the fan 4 is to be closed, the movable plate 8 can be pushed in advance so that the fixed baffle plate 7 corresponding to the movable plate 8 slides into the inner side of the air guide cover 3. During this process, the other movable plate 8 can slide in the opposite direction synchronously under the action of the transmission component, so that the corresponding fixed baffle plate 7 slides into the inner side of the air guide cover 3 synchronously. In this way, the two baffle plates 7 are brought close to each other until they are merged, which can effectively cover the bottom surface of the air guide cover 3, thereby preventing impurities in the filter hole from falling under gravity when the fan 4 is closed.

[0033] Further, refer to Figure 1 As shown, it is worth noting that the transmission component includes two racks 10 staggered up and down and a movable column 11 arranged between the two racks 10, the two racks 10 are respectively fixedly connected to the two movable plates 8, the movable column 11 is vertically rotatably connected to the outer wall of the air deflector 3, and a gear meshing with the rack 10 is fastened and sleeved on the rod body of the movable column 11;

[0034] As shown above, when one of the movable plates 8 is pushed or pulled, the movable plate 8 carries its corresponding fixed rack 10 to slide synchronously, so that the rack 10 slides and meshes with the gear on the movable column 11, and the action gear meshes with the rack 10 on the other movable plate 8, thereby causing the other movable plate 8 to slide in the opposite direction.

[0035] Further, refer to Figure 1 and Figure 3 As shown, it is worth noting that a handle 9 is fixed on one of the movable plates 8;

[0036] The handle 9 can be provided to facilitate manual pushing and pulling of the movable plate 8 .

[0037] Further, refer to Figure 3 As shown, it is worth noting that an auxiliary support component is provided below the barrier plate 7;

[0038] By providing the auxiliary support component, when the baffle plate 7 is pulled out from the inner side of the air deflector 3, the baffle plate 7 can be auxiliary supported from the bottom to prevent the baffle plate 7 from tilting and falling, thereby affecting the use effect.

[0039] Further, refer to Figure 3 As shown, it is worth noting that the auxiliary support component includes a bracket 12 attached to the bottom surface of the barrier plate 7, and a slide 13 slidably connected to the side wall of the support plate 2 is fixed at the bottom end of the bracket 12, and screws 17 are threadedly penetrated at both ends of the slide 13, and a threaded hole adapted to the screw 17 is opened on the side wall of the support plate 2;

[0040] A slide groove 15 is vertically provided on the side wall of the support plate 2, a slider 14 vertically fixed to the slide plate 13 is slidably arranged in the slide groove 15, and a tension spring 16 is fixed between the slider 14 and the inner wall at the bottom end of the slide groove 15;

[0041] After the baffle plate 7 is pulled out from the inner side of the deflector 3, the bracket 12 is manually slid upward so that the bracket 12 contacts the bottom of the baffle plate 7, thereby utilizing the bracket 12 to achieve an auxiliary support effect for the baffle plate 7;

[0042] During the process of the bracket 12 sliding upward, the slide plate 13 carries the slider 14 to slide inside the slide groove 15 and stretch the tension spring 16 to deform. When the bracket 12 moves to contact the barrier plate 7, the knob screw 17 is turned so that the screw 17 penetrates into the threaded hole under the threaded structure, and the slide plate 13 can be locked to offset the tension of the tension spring 16 on the slider 14.

[0043] On the contrary, the knob screw 17 is turned to make the screw 17 withdraw from the threaded hole, thereby releasing the fixing effect on the slide 13 , and the slide block 14 can carry the bracket 12 to slide in the opposite direction under the elastic force of the tension spring 16 , so as to facilitate the recovery of the bracket 12 .
