[0032] Next, in combination with the accompanying drawings and the detailed implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following described embodiments or technical features, and it should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 12 , the present invention provides a technical solution: as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, it includes a boring mechanism 2 for trinity of drilling, boring and dust suction for a circuit board, and a support platform 1 for supporting the boring mechanism 2, wherein the boring mechanism 2 is fixedly installed on the top of the support platform 1; a clamping mechanism 4 for automatically discharging the circuit board after boring; A connecting plate 3 is fixedly connected to the top of the inner cavity of the support platform 1, and one end of the connecting plate 3 away from the support platform 1 is fixedly connected to the clamping mechanism 4.

[0034] Among them, the clamping mechanism 4 includes a middle plate 41, and the outer side of the middle plate 41 is fixedly connected to the connecting plate 3; The sliding connection bar 42 is used for the moving traction treatment of the circuit board and is fixedly connected to the inner side of the middle plate 41; The top of the sliding connection bar 42 and the inside of the middle plate 41 are both slidably fitted with a placement frame 43, and a discharge pipe 44 is fixedly installed on the outer end face of the middle plate 41; The traction plate 45 is used for traction of the processed circuit board and entering into the inside of the discharge pipe 44, and is fixedly connected to the discharge pipe 44. A first magnetic block 46 is fixedly connected to the top of the traction plate 45; The bottom of the inner cavity of the support platform 1 is fixedly installed with an inner connection rail 47. A sliding table 48 is slidably fitted inside the inner connection rail 47, and a fixed seat 49 is fixedly connected to the top of the sliding table 48; The compression spring 40 is used to keep the placement frame 43 and the sliding connection bar 42 parallel during the unloading process, and the upper and lower ends are respectively fixedly connected to the placement frame 43 and the fixed seat 49; the bottom of the placement frame 43 is slidably fitted with the sliding connection bar 42, and its left and right ends are slidably fitted with the inner cavity of the middle plate 41. Therefore, the placement frame 43 will move leftward along the sliding connection bar 42. When it moves to the central part of the sliding connection bar 42, the boring mechanism 2 will do work and perform drilling and boring treatment on the circuit board. Immediately afterwards, when the placement frame 43 moves to the left half of the sliding connection bar 42, because this part of the sliding connection bar 42 is inclined, at this time, the sliding connection bar 42 will no longer be in force balance with the compression spring 40. Finally, under the compression force of the compression spring 40, the placement frame 43 will deflect counterclockwise. At the same time, the placement frame 43 will be parallel to the hypotenuse of the sliding connection bar 42, thus playing a role in pre-unloading treatment of the processed circuit board.

[0035] A fixed shaft 401 is fixedly connected inside the fixed seat 49. Both ends of the fixed shaft 401 are rotatably connected to a shaft connection seat 402, and the top of the shaft connection seat 402 is fixedly connected to the placement frame 43; the circuit board to be processed is placed into the placement frame 43. Then, the sliding table 48 is driven by external power to move leftward along the inner connection rail 47. The top end of the sliding table 48 is connected to the fixed seat 49, and the fixed seat 49 is rotatably connected to the shaft connection seat 402 through the fixed shaft 401. In addition, the top of the shaft connection seat 402 is connected to the placement frame 43. Therefore, the placement frame 43 will deflect with the fixed shaft 401 as the midpoint. And the bottom of the placement frame 43 is connected to the compression spring 40, and the other end of the compression spring 40 is fixedly connected to the outside of the fixed seat 49. The compression spring 40 has a compression force and plays a role in giving the placement frame 43 a counterclockwise deflection force.

[0036] A short rail 403 is fixedly connected to the outer end face of the placement frame 43; The blocking partition 404 is used for limiting the circuit board arranged inside the placement frame 43 and is slidably fitted with the short rail 403; The second magnetic block 405 maintains a repulsive relationship with the first magnetic block 46, so as to move the baffle 404 upward during the unloading process and is fixedly connected to the bottom of the baffle 404. The outer end face of the placement frame 43 is fixedly connected with a short rail 403, and a baffle 404 is slidably fitted inside the short rail 403, and the bottom of the baffle 404 is fixedly connected with a second magnetic block 405. Therefore, when the placement frame 43 is about to approach the inclined first traction plate 45, the first magnetic block 46 fixedly connected to the top of the first traction plate 45 will generate a repulsive force with the second magnetic block 405. Finally, under the action of the repulsive force, the baffle 404 will move upward along the short rail 403 and liberate the circuit board limited by it, causing the circuit board to enter the discharge pipe 44 along the placement frame 43 and the traction plate 45 in sequence, thus playing a role in automatically unloading the processed circuit board.

[0037] As Figure 7 and Figure 8 shown, the boring mechanism 2 includes a vertical rail 21, the vertical rail 21 is fixedly connected to the top of the support table 1, a first motor 22 is fixedly installed at the top of the vertical rail 21, the output end of the first motor 22 penetrates through the top of the vertical rail 21 and is connected with a lead screw 23 through a coupling, and the bottom end of the lead screw 23 is connected to the vertical rail 21 through a bearing; A moving table 24 is threadedly connected to the outside of the lead screw 23, an extension table 25 is fixedly connected to the outside of the moving table 24, and a second motor 26 is fixedly installed on the top of the extension table 25; The output end of the second motor 26 penetrates through the top of the extension table 25 and is connected with a first gear 27 through a coupling. The first gear 27 is arranged inside the extension table 25 and meshes with a second gear 28; The second gear 28 is arranged inside the moving table 24, and a gear shaft 29 is fixedly connected to the center of the second gear 28. An electric push rod 20 is fixedly installed at the bottom of the gear shaft 29, and a boring component 201 is arranged at the bottom of the electric push rod 20. By starting the first motor 22, the lead screw 23 connected to its output end through a coupling will rotate forward, and the moving table 24 threadedly connected to the lead screw 23 will move downward. Then, start the second motor 26, so that the first gear 27 connected to its output end through a coupling will mesh with the second gear 28. The center of the second gear 28 is fixedly connected to the gear shaft 29, and the bottom end of the gear shaft 29 is connected to the electric push rod 20. Therefore, the electric push rod 20 will drive the boring component 201 to move downward together. At this time, the rotating and downward moving drill bit 31 will drill the circuit board.

[0038] As Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, the boring component 201 includes a drill bit 31. The drill bit 31 is rotatably installed inside the moving table 24, and its inner side is fixedly connected to the fixed part of the electric push rod 20; The bottom of the output end of the electric push rod 20 is fixedly connected with a sleeve rod disc 32. The central part of the bottom of the sleeve rod disc 32 is fixedly connected with an inserted rod 33. The outer side of the inserted rod 33 is slidably fitted with a central column 34. The bottom of the central column 34 is fixedly connected with a support rod 35; A hollow bent pipe 36 is sleeved outside the central column 34. A third magnet 37 is fixedly connected inside the hollow bent pipe 36. A first groove is formed inside the hollow bent pipe 36, and a sliding frame 38 is slidably fitted inside the groove. A second groove is formed inside the sliding frame 38, and a sliding block 39 is slidably fitted inside the groove; The vertical end face of the sliding block 39 is fixedly connected with a fourth magnet 30. The fourth magnet 30 and the third magnet 37 maintain an attracting relationship and play a role in resetting the sliding block 39; A first elastic rod 301 is fixedly connected to the top of the inner cavity of the hollow bent pipe 36. The bottom end of the first elastic rod 301 is fixedly connected with a square piston 302. The top of the square piston 302 is fixedly connected with an insertion rod 303. The insertion rod 303 penetrates through the top of the hollow bent pipe 36 and is in pressing fit with the inserted rod 33; A second elastic rod 304 is fixedly connected to the outer side of the sleeve rod disc 32. The bottom end of the second elastic rod 304 is fixedly connected to a first air pipe 305. A perforation 308 is provided at the central part of the first air pipe 305. Additionally, when the second elastic rod 304 drives the first air pipe 305 to move downward, the insertion rod 33 will also enter the central column 34 and exert a downward extrusion on the insertion rod 303. The insertion rod 303 will then drive the square piston 302 fixedly connected to its bottom end to move downward, and compress the gas stored inside the hollow bent pipe 36. The compressed gas will then exert an outward extrusion on the sliding block 39, causing the sliding block 39 to move outward along the groove provided inside the sliding frame 38. At this time, the outward-moving sliding block 39 will just pass through the perforation 308 provided on the surface of the first air pipe 305, thereby achieving the limiting treatment of the first air pipe 305. The outer side of the first air pipe 305 is respectively fixedly connected to a second air pipe 306 and a side connection pipe 309. Sealing laminations 307 are fixedly connected to both the upper and lower sides of the second air pipe 306. One end of the sealing lamination 307 away from the second air pipe 306 is fixedly connected to the outer side of the drill bit 31. When the drilling is completed, the electric push rod 20 is activated. The activation of the electric push rod 20 is divided into two stages. The first stage is that its telescopic end will drive the sleeve rod disc 32 to move downward, and the sleeve rod disc 32 will respectively drive the insertion rod 33 and the second elastic rod 304 to move downward. Among them, the second elastic rod 304 will drive the first air pipe 305 fixedly connected to its bottom end to move downward, causing the first air pipe 305 to exert a downward extrusion on the boring cutter 51. The bored boring cutter 51 will deflect outward through the internal connecting shaft 300, and the deflection angle of the boring cutter 51 will be less than 60°, thereby achieving the boring treatment of the formed hole. Additionally, the first air pipe 305 will continue to move downward and extend out from the bottom of the drill bit 31. Then, the suction device connected to the second air pipe 306 is activated. At this time, the debris cut off during the boring of the hole will enter the lower half of the first air pipe 305, and then enter the upper half of the first air pipe 305 through the side connection pipe 309, and finally be sucked away by the suction device through the second air pipe 306. Thus, when the hole is being bored, it plays a role in absorbing the debris accumulated inside the hole. At the same time, the suction of the suction device will also absorb the heat generated by the friction between the boring cutter 51 and the hole, thereby achieving the all-round cooling treatment of the inside of the hole.

[0039] An inner connecting shaft 300 is fixedly connected inside the drill bit 31. A boring cutter 51 is rotatably connected to the outer side of the inner connecting shaft 300. A resilient block 52 is fixedly connected to the outer side of the boring cutter 51. The resilient block 52 compensates for the notch on the surface of the drill bit 31. One end of the resilient block 52 away from the boring cutter 51 is fixedly connected to the drill bit 31. A resilient strip 53 is fixedly connected to the bottom end of the boring cutter 51. The resilient strip 53 serves to reset the boring cutter 51. The bottom end of the resilient strip 53 is fixedly connected to a fixed disk 54. The fixed disk 54 is fixedly connected to the bottom of the inner cavity of the drill bit 31, and its top is fixedly connected to a support rod 35. In the second stage of the start of the electric push rod 20, since the first air pipe 305 is limited by the sliding block 39, and at the same time the electric push rod 20 still continues to extend downward, the second resilient rod 304 will be compressed at this time, and the inserting rod 33 will continue to exert a downward extrusion on the inserting rod 303. Finally, the sliding block 39 and the sliding frame 38 will all extend outward until the boring cutter 51 is extruded outward for the second time. Finally, the angle between the left half of the boring cutter 51 and the horizontal plane is an acute angle, so as to deflect the angle of the boring cutter 51 for the second time to perform a boring treatment on the holes in the circuit board at a larger angle.

[0040] When the present invention is in use: First, place the circuit board to be processed into the placement frame 43. Then, use external power to drive the slide table 48 to move leftward along the inner track 47. The top of the slide table 48 is connected to the fixed seat 49, and the fixed seat 49 is rotationally connected to the shaft connection seat 402 through the fixed shaft 401. In addition, the top of the shaft connection seat 402 is connected to the placement frame 43. Therefore, the placement frame 43 will deflect with the fixed shaft 401 as the midpoint. The bottom of the placement frame 43 is connected to the compression spring 40, and the other end of the compression spring 40 is fixedly connected to the outside of the fixed seat 49. The bottom of the placement frame 43 is slidably adapted to the sliding strip 42, and its left and right ends are slidably adapted to the inner cavity of the middle plate 41. Therefore, the placement frame 43 will move leftward along the sliding strip 42. When it moves to the central part of the sliding strip 42, the boring mechanism 2 will do work and perform drilling and boring processing on the circuit board. Then, when the placement frame 43 moves to the left half of the sliding strip 42, since this part of the sliding strip 42 is inclined, there will no longer be a force balance between the sliding strip 42 and the compression spring 40 at this time. Finally, under the compression force of the compression spring 40, the placement frame 43 will deflect counterclockwise, and at the same time, the placement frame 43 will be parallel to the hypotenuse of the sliding strip 42. A short track 403 is fixedly connected to the outer end face of the placement frame 43, and a blocking plate 404 is slidably adapted inside the short track 403. The bottom of the blocking plate 404 is fixedly connected to the second magnetic block 405. Therefore, when the placement frame 43 is about to approach the inclined first traction plate 45, the first magnetic block 46 fixedly connected to the top of the first traction plate 45 will generate a repulsive force with the second magnetic block 405. Finally, under the action of the repulsive force, the blocking plate 404 will move upward along the short track 403 and release the circuit board limited by it, causing the circuit board to enter the discharge pipe 44 along the placement frame 43 and the traction plate 45 in sequence.

[0041] By starting the first motor 22, the lead screw 23 connected to its output end through a coupling will rotate forward, and the moving table 24 threadedly connected to the lead screw 23 will move downward. Then, start the second motor 26, so that the first gear 27 connected to its output end through a coupling will mesh and drive with the second gear 28. The central part of the second gear 28 is fixedly connected to the gear shaft 29, and the bottom end of the gear shaft 29 is connected to the electric push rod 20. Therefore, the electric push rod 20 will drive the boring assembly 201 to move downward together. At this time, the rotating and downward moving drill bit 31 will drill the circuit board.

[0042] After the drilling is completed, start the electric push rod 20. The start of the electric push rod 20 is divided into two stages. In the first stage, its telescopic end will drive the sleeve rod disk 32 to move downward, and the sleeve rod disk 32 will drive the inserted rod 33 and the second elastic rod 304 to move downward respectively. Among them, the second elastic rod 304 will drive the first air pipe 305 fixedly connected to its bottom end to move downward, causing the first air pipe 305 to exert a downward extrusion on the boring tool 51. The boring tool 51 under extrusion will deflect outward through the internal connecting shaft 300 to perform boring treatment on the hole after drilling. In addition, the first air pipe 305 will continue to move downward and extend from the bottom of the drill bit 31. Then, start the suction device connected to the second air pipe 306. At this time, the debris cut from the hole will enter the lower half of the first air pipe 305, then enter the upper half of the first air pipe 305 through the side connecting pipe 309, and finally be sucked away by the suction device through the second air pipe 306. In addition, when the second elastic rod 304 drives the first air pipe 305 to move downward, the inserted rod 33 will also enter the central column 34 and exert a downward extrusion on the inserted rod 303. The inserted rod 303 will drive the square piston 302 fixedly connected to its bottom end to move downward and compress the gas stored inside the hollow elbow 36. The compressed gas will exert an outward extrusion on the sliding block 39, causing the sliding block 39 to move outward along the groove opened inside the sliding frame 38. At this time, the outward moving sliding block 39 will just pass through the through hole 308 opened on the surface of the first air pipe 305, so as to limit the first air pipe 305.

[0043] The second stage of the start of the electric push rod 20 is that because the first air pipe 305 is limited by the sliding block 39, and at the same time the electric push rod 20 continues to extend downward, at this time the second elastic rod 304 will be compressed, and the inserted rod 33 will continue to exert a downward extrusion on the inserted rod 303. Finally, the sliding block 39 and the sliding frame 38 will all extend outward until the boring tool 51 is extruded outward for the second time.
