Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0024] Example

[0025] This embodiment provides a circuit board drilling support mechanism with dust removal function, which is used to solve the technical problem that the existing circuit board drilling support mechanism has poor effect in collecting debris. The circuit board drilling support mechanism includes a support box 1, a receiving plate 2, a movable rod 3, an exhaust pipe 4 and a filter plate 5, wherein:

[0026] An opening is provided at the top of the support box 1, and a receiving plate 2 is movably installed at the opening of the support box 1. The receiving plate 2 is used to place holes in the circuit board for drilling, wherein a slot for the drill bit to pass through is provided on the receiving plate 2 to reduce the risk of the drill bit damaging the structure of the receiving plate 2 when drilling.

[0027] The movable rod 3 is movably installed on the side wall of the support box 1, one side of the movable rod 3 abuts against the bottom wall of the receiving plate 2, and the other side of the movable rod 3 extends out of the support box 1, wherein the movable rod 3 moves up and down on the support box 1, and one side of the receiving plate 2 moves up and down with the movable rod 3.

[0028] The exhaust duct 4 is connected to the support box 1, and is used to extract the air in the support box 1 from the exhaust duct 4, wherein the exhaust duct 4 is externally connected to an exhaust fan. When the movable rod 3 moves downward, the exhaust fan exhausts the air inside the support box 1, and the debris on the receiving plate 2 is sucked into the support box 1 through the vent 40.

[0029] The filter plate 5 is installed in the support box 1, and the filter plate 5 is used to filter the air entering the exhaust pipe 4, so that the debris is collected on the filter plate 5 for centralized processing.

[0030] The first state: the movable rod 3 is located at the upper part of the supporting box 1, the receiving plate 2 is arranged horizontally, the receiving plate 2 seals the opening, and the receiving plate 2 can be used for drilling operations.

[0031] The second state: the movable rod 3 is located in the middle of the support box 1 , the receiving plate 2 is tilted, and a vent 40 is formed between the receiving plate 2 and the opening, and debris on the receiving plate 2 enters the support box 1 through the vent 40 .

[0032] Through the above structure, the circuit board drilling support mechanism with dust removal function provided in this embodiment solves the technical problem that the existing circuit board drilling support mechanism has poor effect in collecting debris. Specifically, when the movable rod 3 abuts the receiving plate 2 so that the receiving plate 2 is horizontally arranged, the receiving plate 2 seals the opening, and the circuit board performs the drilling process on the horizontally arranged receiving plate 2. After the drilling is completed, the movable rod 3 is moved to the middle part of the side wall of the support box 1, the receiving plate 2 is tilted, and the debris enters the support box 1 from the vent 40. The exhaust pipe 4 extracts the air in the support box 1, and further sucks the debris on the receiving plate 2 into the support box 1, so that the cleaning of the debris is more thorough. The filter plate 5 collects the debris in the support box 1. Therefore, the circuit board drilling support mechanism with dust removal function filters the debris through the filter plate 5 and collects the debris in the circuit board, reducing the risk of debris polluting the operating environment. The structure is novel and practical. Among them, the exhaust pipe 4 is externally connected to ventilation equipment such as a fan to accelerate the debris on the receiving plate 2 to enter the support box 1.

[0033] An optional implementation of this embodiment is as follows: the support box 1 includes a box body 11, a vertical plate 12 and a correction block 13, the opening is located at the top of the box body 11, the exhaust pipe 4 is installed on the outer bottom wall of the box body 11, the vertical plate 12 is installed in the box body 11, one side of the receiving plate 2 is overlapped on the vertical plate 12, and the correction block 13 is installed at the opening of the box body 11. When the receiving plate 2 is blocked at the opening, the top wall of the receiving plate 2 abuts against the top wall of the correction block 13, and the movable rod 3 and the vertical plate 12 are connected. Support the receiving plate 2 so that one side of the receiving plate 2 overlaps the top of the vertical plate 12, and the other side of the receiving plate 2 overlaps the movable rod 3. When the movable rod 3 moves downward, the receiving plate 2 tilts, and debris enters the box body 11 from the vent 40. When the movable rod 3 abuts the receiving plate 2 against the bottom wall of the correction block 13, the receiving plate 2 seals the opening, and the bottom wall of the correction block 13 is horizontal. When the receiving plate 2 is attached to the bottom wall of the correction block 13, ensure that the horizontality of the receiving plate 2 meets the drilling requirements.

[0034] More preferably, a slide groove 6 is installed on the bottom wall of the receiving plate 2, and the slide groove 6 is located on the side of the receiving plate 2 away from the vertical plate 12. One side of the movable rod 3 is slidably installed in the slide groove 6. Adjustment grooves 7 are respectively opened on the two side walls of the box body 11, and the movable rod 3 is movably installed in the adjusting groove 7. When the movable rod 3 is located at the top of the adjusting groove 7, the receiving plate 2 abuts against the bottom wall of the correction block 13. When the movable rod 3 is located at the lower part of the adjusting groove 7, the debris on the receiving plate 2 enters the box body 11 through the vent 40. When the movable rod 3 moves downward, the movable rod 3 adjusts its relative position with the receiving plate 2 in the slide groove 6 to facilitate the tilted downward movement of the receiving plate 2, making the movement of the receiving plate 2 more convenient. The movable rod 3 is slidably installed in the adjusting groove 7, which limits the moving range of the movable rod 3, makes the movement of the receiving plate 2 more regular, and prevents the receiving plate 2 from moving excessively downward and falling into the supporting box 1.

[0035] More preferably, there are multiple receiving plates 2, and the number of movable rods 3, vertical plates 12 and correction blocks 13 are all multiple. Multiple receiving plates 2 are movably installed end to end at the opening of the box body 11. Two movable rods 3 and a vertical plate 12 are correspondingly installed below any receiving plate 2, and the two movable rods 3 are arranged opposite to the side walls of the box body 11. Two correction blocks 13 are correspondingly installed above any receiving plate 2, and the two correction blocks 13 are arranged opposite to the opening of the box body 11. A guide slope is provided at one end of the receiving plate 2 close to the movable rod 3, and the guide slope abuts against the adjacent receiving plate 2 or the inner wall of the box body 11. In this way, when the receiving plate 2 is changed from a horizontal setting to an oblique setting, the risk of adjacent receiving plates 2 being unable to rotate relative to each other due to the abutment between the side surfaces is reduced. The arrangement of multiple receiving plates 2 facilitates the vent 40 on one side of the receiving plate 2 to be connected as needed, reduces the total area of ​​the vent 40, helps to increase the suction force of the vent 40 on the debris on the receiving plate 2, and improves the cleaning effect.

[0036] Optionally, the adjustment groove 7 includes a transverse groove arranged horizontally and a vertical groove arranged vertically, and one end of the transverse groove close to the vertical plate 12 is connected to the top of the vertical groove. When the movable rod 3 is located in the transverse groove, the receiving plate 2 rests on the bottom wall of the correction block 13. When the movable rod 3 is located at the lower part of the vertical groove, the debris on the receiving plate 2 enters the box body 11 through the vent 40. In this way, when the movable rod 3 is on the transverse groove, the movable rod 3 and the correction block 13 always clamp the receiving plate 2, and the movable rod 3 is not easy to slide down, so that the receiving plate 2 falls off the correction block 13. When the movable rod 3 is located in the vertical groove, the movable rod 3 moves downward, and the area of ​​the vent 40 increases; when the movable rod 3 moves upward, the area of ​​the vent 40 decreases.

[0037] An optional implementation of the present embodiment is as follows: the movable rod 3 includes a moving rod 31, a sealing plate 32, a limit block 33 and an identification block 34. One end of the moving rod 31 is inserted in the slide groove 6, and the other end is located on the outside of the box body 11. The sealing plate 32 is installed in the middle of the moving rod 31, and the sealing plate 32 abuts against the inner wall of the box body 11. The sealing plate 32 is used to seal the vertical groove. The limit block 33 is installed on the moving rod 31, and the limit block 33 slides against the outer wall of the box body 11. The identification block 34 is installed at one end of the moving rod 31 away from the slide groove 6. When the moving rod 31 is located in the vertical groove, the sealing plate 32 seals the vertical groove below the moving rod 31 to prevent air from the side of the box body 11 from entering the box body 11, thereby reducing the dust collection effect of the exhaust duct 4. The identification block 34 is used to determine the orientation of the sealing plate 32 in the box body 11, which helps to determine whether the sealing plate 32 blocks the vertical groove.

[0038] More preferably, the support mechanism for drilling holes in the circuit board also includes a protrusion 8, which is installed at the end of the moving rod 31 away from the identification block 34. The protrusion 8 is used to abut the receiving plate 2 so that the receiving plate 2 abuts against the correction block 13. When the moving rod 31 is located in the transverse groove, the protrusion 8 is rotated to abut the protrusion 8 against the bottom wall of the receiving plate 2, thereby strengthening the fit between the receiving plate 2 and the correction block 13.

[0039] An optional implementation of the present embodiment is as follows: the support mechanism for drilling holes in a circuit board further includes a slide rail 10, a slide frame 20 and a handle 30, the slide rail 10 is mounted on the inner bottom wall of the box body 11, a through opening is provided on one side of the box body 11, the bottom wall of the through opening and the top wall of the slide rail 10 are located on the same plane, the slide frame 20 is slidably mounted on the slide rail 10, one side of the slide frame 20 is sealed at the through opening, the filter plate 5 is sealed on the bottom wall of the slide frame 20, the handle 30 is mounted on the outer side wall of the slide frame 20, and the handle 30 is located outside the box body 11, so that debris is collected on the filter plate 5 in the slide frame 20, and the slide frame 20 is taken out by pulling the handle 30 to clean the debris on the filter plate 5.

[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention.
