DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] like Figure 1-12 As shown, an integrated circuit board hole punching device includes a main circuit board 87, a retaining edge 13 fixedly installed on the top of a hole punching platform 1, and a slidably arranged inclined platform block 8. A mounting frame 2 and a pressure rod 72 are movably arranged in the vertical direction above the hole punching platform 1, and an electric drill 66 is arranged on the mounting frame 2. The pressure rod 72 is assembled for switching between the following three positions:

[0046] Station 1, which is spaced apart from the top of the punching platform 1 and is movably connected to the ramp block 8;

[0047] Station 2 is fitted on the drilling table 1, and the inclined table block 8 and the retaining edge 13 clamp the main circuit board 87, and the electric drill 66 and the main circuit board 87 maintain a predetermined distance;

[0048] Station three, where it is stationary and the electric drill 66 and the main circuit board 87 remain in contact;

[0049] It also includes a main spring 71 between the mounting frame 2 and the pressure rod 72. The main spring 71 maintains power storage when the pressure rod 72 is switched between the two positions of the second position and the third position.

[0050] Specifically, it also includes a support frame 11 fixedly installed on the top of the hole-punching platform 1, and the mounting frame 2 is slidably set on the support frame 11 along the vertical direction, the guide block 7 set below the mounting frame 2 is slidably set on the bottom of the mounting frame 2, and the pressure rod 72 is fixedly installed on the guide block 7, and the two ends of the main spring 71 are respectively fixedly installed on the guide block 7 and the mounting frame 2.

[0051] Furthermore, the ramp block 8 is provided with an inclined portion 82, and the bottom end of the pressure rod 72 is slidably provided on the inclined portion 82, the ramp block 8 is slidably provided with a T-shaped rod 81 on one side of the retaining edge 13, and the ramp block 8 is provided with a knob 83 which is threadedly rotatable, and the T-shaped rod 81 is slidably provided on the ramp block 8 to adjust the distance between the T-shaped rod 81 and the retaining edge 13 by sliding the T-shaped rod 81 on the ramp block 8. Thus, the main circuit board 87 of different widths can be adapted, and then the knob 83 is threadedly rotated so that one end of the knob 83 squeezes the T-shaped rod 81, and then cooperates with the ramp block 8 to fix the T-shaped rod 81 on the ramp block 8.

[0052] Furthermore, a return spring 84 is fixedly mounted on the ramp block 8 , and one end of the return spring 84 is fixedly mounted on the perforated platform 1 .

[0053] Furthermore, the electric drill 66 is fixedly mounted on the mounting frame 2. When it is necessary to drill a hole in the main circuit board 87, the main circuit board 87 is placed on the top of the drilling table 1, and one side of the main circuit board 87 is attached to the retaining edge 13. The main circuit board 87 slides along the retaining edge 13 to move the position where the hole needs to be drilled on the main circuit board 87 to the bottom of the electric drill 66. Then, the mounting frame 2 is driven to move downward and the electric drill 66 moves downward synchronously. At this time, the pressure rod 72 moves downward synchronously with the mounting frame 2. Then, during the downward movement of the pressure rod 72, the bottom end of the pressure rod 72 slides on the inclined portion 82, thereby squeezing and driving the inclined table block 8 to slide and approach the main circuit board 87, and the return spring 84 is pushed by the inclined table block 8 to store force. At this time, the pressure rod 72 is located at the work station one. Then continue to drive the pressure rod 72 downward. At this time, the pressure rod 72 is blocked by the top of the hole-punching platform 1 to stop moving, and the bottom end of the pressure rod 72 is attached to the top of the hole-punching platform 1. At the same time, the pressure rod 72 pushes the ramp block 8 to slide so that the T-bar 81 on the ramp block 8 cooperates with the retaining edge 13 to clamp the main circuit board 87. Then the mounting frame 2 and the electric drill 66 continue to move downward. At this time, the main spring 71 located between the mounting frame 2 and the guide block 7 is squeezed by the mounting frame 2 to store force. At the same time, the electric drill 66 keeps moving downward and close to the main circuit board 87 so that the drill bit end on the electric drill 66 and the main circuit board 87 maintain a predetermined distance, and the predetermined distance is specifically 0-50mm; at this time, the pressure rod 72 is located at the second station. Then the mounting frame 2 and the electric drill 66 continue to move downward, so as to use the electric drill 66 to drill holes in the main circuit board 87. At this time, the pressure rod 72 is stationary because the bottom end is attached to the top of the hole-drilling platform 1, so the T-bar 81 cooperates with the retaining edge 13 to still maintain the state of clamping the main circuit board 87, and the electric drill 66 is in contact with the main circuit board 87 due to drilling. At this time, the pressure rod 72 is located at the third station. When the electric drill 66 is drilling holes in the main circuit board 87 during the downward movement, if the hole is not drilled in place once and needs to be drilled again, the mounting frame 2 is lifted, and the drill bit end of the electric drill 66 is separated from the drilling hole and maintained at a predetermined distance from the surface of the main circuit board 87 again, so that the pressure rod 72 is located at the second station. Then the mounting frame 2 is driven downward again, so that the electric drill 66 can perform secondary drilling, grinding and other operations on the holes already drilled on the main circuit board 87 again. At this time, the pressure rod 72 is located at the third station.

[0054] At the same time, when the pressure rod 72 switches from station three to station two, or when the pressure rod 72 switches from station two to station three, the main spring 71 always maintains a state of storing force, and then under the action of the compression and rebound force of the main spring 71, the bottom end of the pressure rod 72 always remains in contact with the top of the hole-opening platform 1, so that the inclined platform block 8 always remains in a state of being squeezed and limited by the pressure rod 72, and the T-bar 81 cooperates with the retaining edge 13 to always clamp the main circuit board 87, so that when the pressure rod 72 switches arbitrarily between station three and station two, the main circuit board 87 can remain stable, so that the electric drill 66 can perform the drilling operation again.

[0055] Then, when the electric drill 66 has finished drilling, the mounting frame 2 is moved up again to drive the electric drill 66 to move up, thereby switching the pressure rod 72 from station three to station two, and from station two to station one. When the pressure rod 72 switches from station two to station one, the bottom end of the pressure rod 72 gradually separates from the top of the hole-opening platform 1, and the main spring 71 releases the stored force, and then the pressure rod 72 moves up synchronously with the mounting frame 2, and the bottom end of the pressure rod 72 gradually separates from the inclined platform block 8. When the bottom end of the pressure rod 72 is completely separated from the inclined platform block 8, the reset spring 84 is pressed. The T-bar 81 is pushed down to make the T-bar 81 away from the main circuit board 87 and release the clamping of the main circuit board 87, and then the main circuit board 87 is fixed and released by moving the pressure rod 72 and sliding the ramp block 8. Compared with manually operating the clamp to fix the main circuit board 87 as an integrated circuit board, it can achieve rapid fixing and releasing. At the same time, compared with the driving source of an external electric push rod cooperating with the clamp to fix the main circuit board 87, the pressure rod 72 moves down with the electric drill 66 when drilling, which can avoid the cumbersome adjustment of the control program and other problems.

[0056] Furthermore, the mounting frame 2 may be driven to move up or down by using an electric push rod to push the mounting frame 2 up or down; or by using a motor in conjunction with a lead screw and a nut; or by any other method known to those skilled in the art to drive the mounting frame 2 to move up or down.

[0057] In the above technical scheme, the main circuit board 87 is placed on the top of the hole punching table 1 and the main circuit board 87 is attached to the retaining edge 13, and then the mounting frame 2 is driven downward to make the electric drill 66 close to the main circuit board 87, and then the bottom end of the pressure rod 72 squeezes the ramp block 8 to slide and is located at station one. As the pressure rod 72 continues to move downward and is located at station two, the pressure rod 72 is blocked by the top of the hole punching table 1 to stop moving, and the ramp block 8 cooperates with the retaining edge 13 to clamp and fix the main circuit board 87, and the electric drill 66 and the main circuit board 87 maintain a predetermined distance, and then the pressure rod 72 continues to move downward and is located at station three. At this time, the electric drill 66 drills the main circuit board 87. When the pressure rod 72 switches from station three to station one, the pressure rod 72 releases the squeezing of the ramp block 8 to release the main circuit board 87 from the ramp block 8, and then the pressure rod 72 is used to cooperate with the ramp block 8 to achieve the operation of quickly fixing and quickly releasing the main circuit board 87.

[0058] As an embodiment further provided by the present invention, it also includes a transverse frame 3 sliding on the mounting frame 2 and a mounting box 4 slidingly arranged along the bottom of the mounting frame 2, and the moving directions of the transverse frame 3 and the mounting box 4 are vertical, and the electric drill 66 is fixedly installed in the mounting box 4.

[0059] Specifically, the support frame 11 is fixedly mounted with a connecting frame 12, and the connecting frame 12 is fixedly mounted with a main electric push rod 28, the top of the mounting frame 2 is fixedly mounted with a beam frame 21, and the output end of the main electric push rod 28 is fixedly mounted on the top of the beam frame 21, the beam frame 21 is rotatably provided with a first screw rod 23, and the transverse frame 3 is threadedly rotatably provided on the first screw rod 23, as shown in FIG. Figure 4 As shown, a first shield 22 is fixedly installed on the beam frame 21, and a first adjustment motor 24 is fixedly installed in the first shield 22, a transmission shaft 25 is rotatably arranged in the first shield 22, and a first pulley 26 is fixedly installed on the output end of the first adjustment motor 24 and the outer wall of the transmission shaft 25, respectively, and a belt transmission is passed between the two first pulleys 26, and the first screw rod 23 and the adjacent ends of the transmission shaft 25 are respectively fixedly installed with first wedge gears 27 that mesh with each other, so that the first adjustment motor 24 rotates to cooperate with the first pulley 26 to rotate the transmission shaft 25, and then the transmission shaft 25 and the first screw rod 23 are meshed with each other through the first wedge gears 27 respectively arranged at the adjacent ends, so that the first screw rod 23 rotates, and at this time the transverse frame 3 and the first screw rod 23 are threadedly rotated and rotate along Figure 1 Slide on the mounting frame 2 in the direction of the X-axis arrow.

[0060] like Figure 4 As shown, a second screw rod 31 is rotatably provided on the transverse frame 3, a second shield 34 is fixedly installed on the top of the transverse frame 3, a second adjustment motor 33 is fixedly installed in the second shield 34, and a second wedge-shaped gear 32 meshing with each other is fixedly installed at the output end of the second adjustment motor 33 and the adjacent end of the second screw rod 31, and the mounting box 4 is threadedly rotatably provided on the second screw rod 31, so that the second screw rod 31 is driven to rotate by the rotation of the second adjustment motor 33 and then the output end of the second adjustment motor 33 and the adjacent end of the second screw rod 31 are meshed with each other, and then the mounting box 4 is threadedly rotated on the second screw rod 31 and rotated along the second screw rod 31. Figure 1 The middle Y-axis slides on the horizontal frame 3 in the direction of the arrow. Since the moving directions of the horizontal frame 3 and the installation box 4 are vertical, the moving directions of the horizontal frame 3 and the installation box 4 cooperate with each other, so that the electric drill 66 fixedly installed in the installation box 4 can be moved and adjusted on a horizontal plane to perform drilling operations.

[0061] Therefore, when drilling is required for the main circuit board 87, the main circuit board 87 as the integrated circuit board is placed on the top of the drilling platform 1 and the main circuit board 87 is attached to the retaining edge 13, and then the first adjustment motor 24 and the second adjustment motor 33 are driven respectively to adjust the installation box 4 in the hole. Figure 1The precise position in the X-axis direction and the Y-axis direction of the middle part can be determined, so that the drill bit end of the electric drill 66 can be aligned, and the corresponding control of the adjustment in the X-axis direction and the Y-axis direction can be achieved by using a corresponding detection unit, and the detection unit can use laser detection, camera detection, etc., to find the position where the hole needs to be drilled on the main circuit board 87, and then drive the first adjustment motor 24 and the second adjustment motor 33 through the control program to adjust the specific position of the electric drill 66 on the installation box 4, and perform an accurate drilling operation. How to control and adjust the first adjustment motor 24 and the second adjustment motor 33 and the corresponding laser detection and camera detection of the detection unit are common knowledge known to those skilled in the art, and will not be elaborated here.

[0062] Then, the main electric push rod 28 is used to push the beam frame 21 downward, thereby driving the electric drill 66 in the installation box 4 to move downward. At this time, the pressure rod 72 moves downward synchronously with the beam frame 21, and then during the downward movement of the pressure rod 72, the bottom end of the pressure rod 72 slides on the inclined portion 82, thereby squeezing and driving the ramp block 8 to slide and approach the main circuit board 87. It can be seen that the elastic force of the main spring 71 can overcome the resistance that drives the ramp block 8 to slide, and then the return spring 84 is pushed by the sliding of the ramp block 8 to store force. At this time, the pressure rod 72 is located at station one. Then continue to drive the pressure rod 72 downward. At this time, the pressure rod 72 is blocked by the top of the hole-punching platform 1 to stop moving, and the bottom end of the pressure rod 72 is attached to the top of the hole-punching platform 1. At the same time, the pressure rod 72 pushes the ramp block 8 to slide so that the T-bar 81 on the ramp block 8 cooperates with the retaining edge 13 to clamp the main circuit board 87. Then the mounting frame 2 and the electric drill 66 continue to move downward. At this time, the main spring 71 located between the mounting frame 2 and the guide block 7 is squeezed by the mounting frame 2 to store force. At the same time, the electric drill 66 keeps moving downward and close to the main circuit board 87 so that the drill bit end on the electric drill 66 and the main circuit board 87 maintain a predetermined distance. At this time, the pressure rod 72 is located at the second station. Then the mounting frame 2 and the electric drill 66 continue to move downward to use the electric drill 66 to drill holes in the main circuit board 87. At this time, the pressure rod 72 is stationary because the bottom end is attached to the top of the hole-drilling platform 1. Therefore, the T-bar 81 cooperates with the retaining edge 13 to still keep the main circuit board 87 clamped, and the electric drill 66 keeps in contact with the main circuit board 87 due to drilling. At this time, the pressure rod 72 is located at station three.

[0063] Furthermore, when drilling a hole at one point on the main circuit board 87 is completed and other points need to be drilled, the main electric push rod 28 is driven again to control the mounting frame 2 to be lifted, and the drill bit end of the electric drill 66 is separated from the drilling hole and maintained at a predetermined distance from the surface of the main circuit board 87 again, so that the pressure rod 72 is located at the second station. Then the first adjustment motor 24 and the second adjustment motor 33 are driven again to adjust the position of the transverse frame 3 on the mounting frame 2 in the X-axis direction and the position of the installation box 4 on the transverse frame 3 in the Y-axis direction, so that the electric drill 66 in the installation box 4 is positioned again at the next point to be drilled. When the new point is found and adjusted, the main electric push rod 28 is controlled again and the mounting frame 2 is driven downward, so that the electric drill 66 drills the new point on the main circuit board 87 again.

[0064] As another embodiment further provided by the present invention, a pressure plate 85 is hingedly provided on a T-shaped rod 81 slidably provided on the outer wall of one side of the ramp block 8, and the airbag 86 provided on one side of the T-shaped rod 81 and the main circuit board 87 are blocked and cooperated, and the airbag 86 is compressed and expanded to push the pressure plate 85 down onto the main circuit board 87.

[0065] Specifically, the T-shaped rod 81 is slid on the ramp block 8 to adjust the distance between the T-shaped rod 81 and the retaining edge 13, so as to adapt to the main circuit board 87 of different widths, and then the knob 83 is screwed to make one end of the knob 83 squeeze the T-shaped rod 81, and then cooperate with the ramp block 8 to fix the T-shaped rod 81 on the ramp block 8.

[0066] like Fig.11 As shown, the airbag 86 is fixedly mounted on the T-bar 81, and the airbag 86 is located on one side of the bottom end of the pressure plate 85. Therefore, when the bottom end of the pressure bar 72 slides on the inclined portion 82 to squeeze and drive the ramp block 8 to slide and approach the main circuit board 87, the airbag 86 on the T-bar 81 continuously approaches and finally fits on the main circuit board 87. Under the squeezing of the main circuit board 87 by the T-bar 81 and the retaining edge 13, the airbag 86 is squeezed, so that the airbag 86 expands relative to one side of the main circuit board 87 and squeezes the bottom end of the push plate 85. At this time, the top end of the pressure plate 85 begins to flip down toward the side of the main circuit board 87, and then during the flipping down of the pressure plate 85, the pressure plate 85 covers the main circuit board 87, so that the pressing plate 85 can limit and block the main circuit board 87 by utilizing the flipping down of the pressure plate 85 and the expansion of the airbag 86. At the same time, the airbag 86 is used as a connector between the T-bar 81 and the main circuit board 87, so as to avoid the problem of the main circuit board 87 being pinched due to the hard contact between the T-bar 81 and the main circuit board 87, thereby improving the protection effect of the main circuit board 87.

[0067] Furthermore, when the pressure rod 72 releases the pressure on the ramp block 8, the ramp block 8 is pushed back by the return spring 84 to make the T-bar 81 move away from the main circuit board 87, and the airbag 86 is reset at this time.

[0068] As another optimal embodiment provided by the present invention, the top of the drilling station 1 is rotatably provided with a driving wheel 98 located below the main circuit board 87, and the driving wheel 98 rotates when the pressure rod 72 switches from station two to station one.

[0069] Specifically, the driving wheel 98 is rotatably arranged on the top of the drilling platform 1, and the wheel surface of the driving wheel 98 protrudes 1-2mm from the top of the drilling platform 1. When all the drilling points on the main circuit board 87 are drilled, the main electric push rod 28 is used to drive the electric drill 66 to move up, and the pressure rod 72 is switched from the second station to the first station. When the pressure rod 72 is switched from the second station to the first station, the main spring 71 releases the stored force. At this time, the bottom end of the pressure rod 72 gradually separates from the top of the drilling platform 1, and then the pressure rod 72 moves up synchronously with the mounting frame 2, and the pressure rod 72 is moved upward synchronously. 2 gradually separates from the ramp block 8. When the bottom end of the pressure rod 72 completely separates from the ramp block 8, the T-bar 81 is pushed away from the main circuit board 87 by the return spring 84 and the clamping of the main circuit board 87 is released. Since the T-bar 81 releases the clamping of the main circuit board 87, the driving wheel 98 is driven to rotate, thereby driving the main circuit board 87 to move to the top of the hole-punching table 1, and the main circuit board 87 can be moved to the next step of cleaning the circuit board, thereby reducing the steps for workers to take and transport the main circuit board 87.

[0070] The driving wheel 98 may be driven to rotate by using an electric push rod in conjunction with a rack and a gear; it may also be driven by a motor; or any other method known to those skilled in the art to drive the driving wheel 98 to rotate.

[0071] As an optimal embodiment further provided by the present invention, it also includes a pulling rod 73 that moves synchronously with the pressure rod 72, a ratchet 9 that is rotatably arranged inside the hole-drilling table 1 and cooperates with the driving wheel 98 in gear transmission, and a plurality of tooth blocks 75 arranged in a linear array are hingedly arranged on the outer wall of the pulling rod 73, and the tooth block 75 engages with the ratchet 9 when the pressure rod 72 switches from station two to station one.

[0072] Specifically, the draw rod 73 is fixedly mounted on the guide block 7, as shown in FIG. Figure 2 and Figure 7 As shown, the outer wall on one side of the draw rod 73 is provided with receiving grooves 74 arranged in a linear array, and the tooth blocks 75 are respectively hingedly arranged in the receiving grooves 74, and the tooth blocks 75 are fixedly mounted with receiving springs 76, and the first end of the receiving spring 76 is fixedly mounted on the draw rod 73.

[0073] Further, such as Figure 6As shown, a large toothed disc 93 and a small toothed disc 94 are rotatably arranged in the hole-opening platform 1, and second pulleys 91 are fixedly installed on the outer walls of the shafts of the large toothed disc 93 and the ratchet 9, respectively, and the two second pulleys 91 are driven by a belt, and the large toothed disc 93 and the small toothed disc 94 are meshed with each other. A change-of-direction shaft 96 is rotatably arranged in the hole-opening platform 1, and third wedge-shaped gears 95 meshing with each other are fixedly installed on the adjacent ends of the shafts of the change-of-direction shaft 96 and the small toothed disc 94, and third pulleys 97 are fixedly installed on the outer walls of the change-of-direction shaft 96 and the outer walls of the shafts of the driving wheel 98, respectively, and the two third pulleys 97 are driven by a belt. An elastic plate 92 is fixedly installed in the hole-opening platform 1, and one end of the elastic plate 92 is inserted into the tooth opening of the ratchet 9.

[0074] Therefore, when it is necessary to drill a hole in the main circuit board 87, the main circuit board 87 is placed on the top of the drilling platform 1 and on the side of the retaining edge 13, and then the main electric push rod 28 is used to push the beam frame 21 downward, thereby driving the electric drill 66 in the installation box 4 to move downward. At this time, the installation frame 2 cooperates with the main spring 71 to drive the guide block 7 to move downward, and then the pull rod 73 and the pressure rod 72 move downward synchronously with the beam frame 21.

[0075] Then, when the pressure rod 72 moves downward, the bottom end of the pressure rod 72 slides on the inclined portion 82, thereby squeezing and driving the ramp block 8 to slide and approach the main circuit board 87, and then the return spring 84 is pushed by the ramp block 8 to accumulate force, and at the same time, the draw rod 73 moves downward to slide in the hole opening platform 1. When the draw rod 73 moves downward, at this time, Figure 2 , Figure 6 and Figure 7 As shown, the tooth block 75 moves on the ratchet 9, because one end of the elastic plate 92 is inserted into the tooth opening of the ratchet 9 to prevent the ratchet 9 from rotating in the opposite direction, and the tooth block 75 is turned over in the receiving groove 74 under the blocking and pushing of the ratchet 9, and then when the tooth block 75 is separated from the ratchet 9, the receiving spring 76 pushes the tooth block 75 to return to its original position. At this time, the pressure rod 72 is at the first station.

[0076] Then continue to drive the pressure rod 72 downward, at this time the pressure rod 72 is blocked by the top of the hole-drilling platform 1 to stop moving, and the draw rod 73 also stops moving. Then the bottom end of the pressure rod 72 fits the top of the hole-drilling platform 1, and at the same time the pressure rod 72 pushes the ramp block 8 to slide so that the T-shaped rod 81 on the ramp block 8 cooperates with the retaining edge 13 to clamp the main circuit board 87, and then the mounting frame 2 and the electric drill 66 continue to move downward, at this time the main spring 71 located between the mounting frame 2 and the guide block 7 is squeezed by the mounting frame 2 to store force, and at the same time the electric drill 66 keeps moving downward and close to the main circuit board 87 so that the drill bit end on the electric drill 66 and the main circuit board 87 maintain a predetermined distance, and at this time the pressure rod 72 is located at the second station. Then the mounting frame 2 and the electric drill 66 continue to move downward to use the electric drill 66 to drill the main circuit board 87, and the pressure rod 72 is located at the third station.

[0077] When all the drilling points on the main circuit board 87 are drilled, the main electric push rod 28 is used to drive the electric drill 66 to move upward, and the pressure rod 72 is switched from station two to station one. When the pressure rod 72 is switched from station two to station one, the main spring 71 releases the stored force, and the bottom end of the pressure rod 72 gradually separates from the top of the hole-opening platform 1, and then the pressure rod 72 moves upward synchronously with the mounting frame 2, and the bottom end of the pressure rod 72 gradually separates from the ramp block 8. When the bottom end of the pressure rod 72 is completely separated from the ramp block 8, the reset spring 84 pushes the T-bar 81 away from the main circuit board 87 and releases the clamping of the main circuit board 87. At the same time, when the pressure rod 72 moves up and leaves the top of the drilling platform 1 and the T-shaped rod 81 releases the clamping of the main circuit board 87, the draw rod 73 moves up synchronously with the pressure rod 72. As the draw rod 73 moves up, the multiple tooth blocks 75 on the draw rod 73 are sequentially embedded in the teeth of the ratchet 9 and the ratchet 9 is driven to rotate forwardly. Figure 6 As shown, when the ratchet 9 rotates forward, the ratchet 9 moves the elastic plate 92 to make the elastic plate 92 free from the locking of the ratchet 9. As the ratchet 9 rotates, the belt transmission between the two second pulleys 91 is coordinated to make the large toothed disc 93 rotate and mesh with the small toothed disc 94. The meshing between the large toothed disc 93 and the small toothed disc 94 realizes the speed change effect, and then the small toothed disc 94 rotates to make the third wedge gear 95 on its shaft mesh with the third wedge gear 95 on the change shaft 96, thereby driving the change shaft 96 to rotate, and then the change shaft 96 and the driving wheel 98 are driven by the belt between the two third pulleys 97 to make the driving wheel 98 rotate, and because the main circuit board 87 has been released from the clamping, the main circuit board 87 is driven to move to the top of the hole-opening table 1 through the rotation of the driving wheel 98 to realize the operation of transporting the main circuit board 87.

[0078] As another embodiment further provided by the present invention, a bottom box 5 is slidably provided on the outer wall of the installation box 4, and the exhaust chambers 42 symmetrically arranged in the installation box 4 are respectively connected to the exhaust ducts 53 symmetrically arranged in the bottom box 5, and a gray box 43 connected to the two exhaust chambers 42 is plugged into the installation box 4.

[0079] Specifically, Figure 4 As shown, the installation box 4 is symmetrically fixed with plug boxes 41 connected to the two exhaust chambers 42, and the two plug boxes 41 are slidably arranged in the exhaust ducts 53, and the pulling springs 47 are symmetrically arranged between the installation box 4 and the bottom box 5, and the two ends of the pulling springs 47 are respectively fixedly installed on the installation box 4 and the bottom box 5. The electric drill 66 is fixedly installed on the installation box 4 and moves in the bottom box 5, and the electric drill 66 moves between the two exhaust ducts 53.

[0080] like Figure 8As shown, the installation box 4 is provided with an exhaust bin 44, which is plugged into the installation box 4 through an ash box 43, so that the exhaust bin 44 is connected to the two exhaust chambers 42 through the ash box 43, and a suction blade 46 is rotatably arranged in the exhaust bin 44, and the suction blade 46 is driven by a motor to rotate so as to form a negative pressure in the exhaust bin 44, so as to suck the two exhaust chambers 42 through the ash box 43, so as to form a negative pressure in the two exhaust ducts 53 by using two plug boxes 41 to suck the waste. A filter rack 45 is fixedly installed in the ash box 43, and the exhaust bin 44 is blocked by the filter rack 45, so that the sucked waste stays in the ash box 43 for collection, so as to clean the waste by plugging and unplugging the ash box 43.

[0081] Therefore, when the pressure rod 72 is in the second station, the T-bar 81 cooperates with the retaining edge 13 to clamp the main circuit board 87. As the electric drill 66 continues to approach the main circuit board 87, the bottom end of the bottom box 5 first covers the main circuit board 87, and then the installation box 4 slides in the bottom box 5 to allow the electric drill 66 to continue to approach the main circuit board 87. At the same time, the pulling spring 47 is squeezed and stored, and the plug-in boxes 41 are slidably set in the exhaust duct 53.

[0082] When the pressure rod 72 is in the third station, the electric drill 66 performs a drilling operation on the main circuit board 87. At this time, the waste chips generated by the drilling of the electric drill 66 are sucked through the two exhaust ducts 53, so as to clean the surface of the main circuit board 87 in time for the subsequent drilling. At the same time, the bottom box 5 is symmetrically provided with air outlets 51, which are covered on the main circuit board 87 through the bottom box 5 to shield the waste chips generated by the drilling of the electric drill 66 to reduce the splashing of the waste chips. At the same time, due to the suction of the exhaust duct 53, the external air enters the bottom box 5 along the air outlets 51.

[0083] As another embodiment further provided by the present invention, an airway hole 54 is symmetrically arranged in the bottom box 5 with one end inclined toward the top of the main circuit board 87, and the piston chambers 52 symmetrically arranged in the bottom box 5 are respectively connected to the airway holes 54;

[0084] It also includes a sealing plate 57 slidably arranged in the piston chamber 52 , and the sealing plate 57 and the mounting box 4 move synchronously to allow the airway hole 54 and the piston chamber 52 to communicate with each other.

[0085] Specifically, Fig.10As shown, a piston plate 56 is slidably provided in the piston cavity 52, and a push rod 55 fixedly mounted on the piston plate 56 slides on the bottom box 5, and the top end of the push rod 55 fits on the mounting box 4, a compression spring is fixedly mounted in the piston cavity 52, and the first end of the compression spring is fixedly mounted on the piston plate 56, a single air valve 99 is fixedly mounted on the inner wall of one side of the piston cavity 52, a sealing plate 57 is fixedly mounted on the piston plate 56, and an exhaust port 58 is opened on the sealing plate 57, and the sealing plate 57 is in a default state to fit on the inner wall of one side of the piston cavity 52 and block the airway hole 54.

[0086] Then, when the pressure rod 72 is in the second station, the T-bar 81 cooperates with the retaining edge 13 to clamp the main circuit board 87. As the electric drill 66 continues to approach the main circuit board 87, the bottom end of the bottom box 5 first covers the main circuit board 87, and then the installation box 4 slides in the bottom box 5. The pulling spring 47 is squeezed and accumulates force. At the same time, the installation box 4 presses down the two push rods 55, so that the push rods 55 drive the piston plate 56 to slide in the piston chamber 52. At this time, the single-vent valve 99 is closed. Because the sealing plate 57 blocks the airway hole 54, the gas in the piston chamber 52 cannot be discharged to increase the air pressure. At the same time, the compression spring in the piston chamber 52 is squeezed to accumulate force.

[0087] When the pressure rod 72 is at the third station, the electric drill 66 continues to move downward to start drilling the main circuit board 87. At this time, the sealing plate 57 is pushed downward by the mounting box 4 to connect the exhaust port 58 with the airway hole 54, so that the compressed gas in the piston chamber 52 is continuously and quickly discharged along the exhaust port 58 and the airway hole 54. Since one end of the airway hole 54 is inclined toward the top of the main circuit board 87, the waste generated by the electric drill 66 drilling the main circuit board 87 is blown from the main circuit board 87 under the blowing of the airway hole 54, and then the two exhaust ducts 53 are used to suck the waste generated by the electric drill 66 drilling, so as to clean the surface of the main circuit board 87 in time for the subsequent drilling. Therefore, the blowing of the airway hole 54 can make some waste attached to the surface of the main circuit board 87 be blown up, and then sucked and cleaned by the exhaust duct 53, thereby solving the problem that the waste attached to the surface of the main circuit board 87 is not easy to be sucked up by the exhaust duct 53.

[0088] As another embodiment further provided by the present invention, a vibration plate 64 is fixedly installed at the bottom of the bottom box 5, and the vibration plate 64 vibrates when the pressure rod 72 switches from the third station to the second station.

[0089] Specifically, when the electric drill 66 finishes drilling a hole at a drilling point and is pulled out from the hole on the main circuit board 87, the pressure rod 72 switches from station three to station two. At this time, the pulling spring 47 releases the stored force to push the bottom box 5 so that the bottom of the bottom box 5 continues to fit on the main circuit board 87. At the same time, the compression spring releases the stored force to push the piston plate 56 to reset. At the same time, the single-vent valve 99 opens to allow external air to enter the piston chamber 52 along the single-vent valve 99 again, and the sealing plate 57 moves up to make the exhaust port 58 and the airway hole 54 misaligned and disconnected again.

[0090] When the electric drill 66 is pulled out from the drill hole on the main circuit board 87, the vibration plate 64 is driven to vibrate to drive the main circuit board 87 around the drill hole to vibrate, and then the vibration is transmitted to the drill hole, so that the debris attached to the inner wall of the drill hole falls off along with the vibration, and then the exhaust duct 53 is used to suck and clean the waste chips in the drill hole.

[0091] The vibration plate 64 can be vibrated by using the output end of the vibration motor to directly contact the vibration plate 64; or by using a motor in conjunction with a cam to continuously impact the vibration plate 64 to generate vibration; or by any method known to those skilled in the art to drive the vibration plate 64 to vibrate.

[0092] As an optimal embodiment further provided by the present invention, a follower block 6 is symmetrically slidably arranged in the bottom box 5, and the first end of the follower block 6 is movably arranged in an arc groove 59 arranged in a linear array on the sealing plate 57 for vibration, and the follower block 6 and the vibration plate 64 are movably connected.

[0093] Specifically, Fig.12 As shown, a vibration spring 62 is fixedly mounted on the second end of the follower block 6, and a first end of the vibration spring 62 is fixedly mounted on the bottom box 5, a shift plate 65 is fixedly mounted on the vibration plate 64, and an extension rod 63 is fixedly mounted on the follower block 6 which is attached to the shift plate 65 in a default state, and a curved surface portion 61 is provided on the first end of the follower block 6, so that the first end of the follower block 6 can move and switch between multiple arc grooves 59 more smoothly.

[0094] Therefore, when the pressure rod 72 is in the second station, the T-bar 81 cooperates with the retaining edge 13 to clamp the main circuit board 87. As the electric drill 66 continues to approach the main circuit board 87, the bottom end of the bottom box 5 first covers the main circuit board 87, and then the installation box 4 slides in the bottom box 5. The pulling spring 47 is squeezed and accumulates force. At the same time, the installation box 4 presses down the two push rods 55, so that the push rods 55 drive the piston plate 56 to slide in the piston cavity 52. ​​At this time, the sealing plate 57 on the piston plate 56 moves downward synchronously with the piston plate 56, so that the first end of the follower block 6 continuously switches and moves between multiple arc grooves 59 and gradually approaches the arc groove 59 at a high position.

[0095] Then, when the pressure rod 72 is in the third position and the electric drill 66 continues to move downward and drill holes in the main circuit board 87, the first end of the follower block 6 continues to switch and move along the multiple arc grooves 59 and gradually approaches the arc groove 59 at the high position. When a drilling point on the main circuit board 87 is completed, the electric drill 66 is pulled out of the drill hole on the main circuit board 87. At this time, the pulling spring 47 releases the stored force to push the bottom box 5 so that the bottom of the bottom box 5 continues to fit on the main circuit board 87. At the same time, the compression spring releases the stored force to push the piston plate 56 to reset. At the same time, the single-vent valve 99 opens to allow external air to enter the piston chamber 52 along the single-vent valve 99 again. The sealing plate 57 moves upward synchronously with the electric drill 66 under the push of the compression spring. At this time, the sealing plate 57 moves upward relative to the follower block 6, and then the first end of the follower block 6 begins to switch and move downward along the multiple arc grooves 59. When the first end of the follower block 6 moves along one of the arc grooves When the groove 59 switches to another arc groove 59, the follower block 6 is pushed to slide to compress the vibration spring 62. At this time, the extension rod 63 moves away from the paddle plate 65, and then the vibration spring 62 continues to push the follower block 6 to reset, and the extension rod 63 hits the paddle plate 65, thereby driving the paddle plate 65 to generate a certain vibration. Therefore, when the follower block 6 switches between multiple arc grooves 59, the paddle plate 65 vibrates to transmit the vibration to the main circuit board 87, thereby driving the main circuit board 87 around the drill hole to vibrate, and then the vibration is transmitted to the drill hole, accompanied by the vibration so that the debris attached to the inner wall of the drill hole falls off, and then accompanied by the suction of the exhaust duct 53 to suck and clean the waste chips in the drill hole.

[0096] The hole-opening method of the integrated circuit board hole-opening device comprises the following steps:

[0097] S1, by placing the main circuit board 87 on the top of the drilling platform 1 and on one side of the retaining edge 13, and then using the main electric push rod 28 to push the beam frame 21 downward, thereby driving the electric drill 66 in the installation box 4 to move downward, at this time, the installation frame 2 cooperates with the main spring 71 to drive the guide block 7 to move downward, and then the draw rod 73 and the pressure rod 72 move downward synchronously with the beam frame 21, and then during the downward movement of the pressure rod 72, the bottom end of the pressure rod 72 slides on the inclined portion 82, thereby squeezing and driving the inclined table block 8 to slide and approach the main circuit board 87, and then the return spring 84 is pushed by the inclined table block 8 to accumulate force, and at the same time the draw rod 73 moves downward to slide in the drilling platform 1, and at this time the pressure rod 72 is located at the first station;

[0098] S2, because the draw rod 73 and the pressure rod 72 move downward synchronously, when the draw rod 73 moves downward, Figure 2 , Figure 6 and Figure 7As shown, the tooth block 75 moves on the ratchet 9, because one end of the elastic plate 92 is inserted into the tooth opening of the ratchet 9 so that the ratchet 9 does not rotate in the reverse direction, and the tooth block 75 is pushed and turned in the receiving groove 74 under the shielding of the ratchet 9, and then when the tooth block 75 is separated from the ratchet 9, the receiving spring 76 pushes the tooth block 75 to return to its original position;

[0099] S3, under the push of the main circuit board 87, the pressure rod 72 continues to move downward, and at this time, the pressure rod 72 is blocked by the top of the hole-drilling platform 1 and stops moving, and the draw rod 73 also stops moving. Then the bottom end of the pressure rod 72 fits the top of the hole-drilling platform 1, and at the same time, the pressure rod 72 pushes the ramp block 8 to slide so that the T-shaped rod 81 on the ramp block 8 cooperates with the retaining edge 13 to clamp the main circuit board 87, and then the mounting frame 2 and the electric drill 66 continue to move downward, and at this time, the main spring 71 located between the mounting frame 2 and the guide block 7 is squeezed by the mounting frame 2 to store force, and at the same time, the electric drill 66 keeps moving downward and close to the main circuit board 87 so that the drill bit end on the electric drill 66 and the main circuit board 87 maintain a predetermined distance, and at this time, the pressure rod 72 is located at the second station;

[0100] S4, when the pressure rod 72 is located at the second station, as the installation box 4 drives the electric drill 66 to continue to move downward, the bottom of the bottom box 5 is first attached to the main circuit board 87, and then the installation box 4 continues to approach the main circuit board 87 to move relative to the bottom box 5. At this time, the pulling spring 47 is squeezed and stored. At the same time, the installation box 4 presses down the two push rods 55, so that the push rods 55 drive the piston plate 56 to slide in the piston cavity 52. ​​At this time, the single-vent valve 99 is closed. Because the sealing plate 57 blocks the airway hole 54, the gas in the piston cavity 52 cannot be discharged to increase the air pressure. At the same time, the compression spring in the piston cavity 52 is squeezed to store force. At the same time, the first end of the follower block 6 continuously switches and moves between the multiple arc grooves 59 on the sealing plate 57 and gradually approaches the arc groove 59 at the high position;

[0101] S5. As the sealing plate 57 and the installation box 4 move synchronously, when the pressure rod 72 is in the third position, the electric drill 66 continues to move downward to start drilling holes in the main circuit board 87. At this time, the sealing plate 57 is pushed downward by the installation box 4 to connect the exhaust port 58 with the airway hole 54, so that the compressed gas in the piston chamber 52 is continuously and quickly discharged along the exhaust port 58 and the airway hole 54. Since one end of the airway hole 54 is inclined toward the top of the main circuit board 87, the waste chips generated by the drilling of the main circuit board 87 by the electric drill 66 are blown from the main circuit board 87 under the blowing of the airway hole 54, and then the waste chips generated by the drilling of the electric drill 66 are sucked in cooperation with the two exhaust ducts 53, and the first end of the follower block 6 continues to switch and move between the multiple arc grooves 59 on the sealing plate 57 and continues to gradually approach the arc groove 59 at the high position;

[0102] S6. When a hole is drilled at a drilling point on the main circuit board 87, the pressure rod 72 switches from station three to station two. At this time, the pulling spring 47 releases the stored force to push the bottom box 5 so that the bottom of the bottom box 5 continues to fit on the main circuit board 87. At the same time, the compression spring releases the stored force to push the piston plate 56 to reset. At the same time, the single-vent valve 99 opens to allow external air to enter the piston chamber 52 along the single-vent valve 99 again. At the same time, the electric drill 66 is pulled out from the drill hole on the main circuit board 87. At this time, the sealing plate 57 moves up synchronously with the electric drill 66 under the push of the compression spring. At the same time, the sealing plate 57 moves up relative to the follower block 6, and then the first end of the follower block 6 starts to switch and move down along a plurality of arc grooves 59. When the first end of the follower block 6 moves along one of the arc grooves When the arc groove 59 switches to another arc groove 59, the follower block 6 is pushed to slide to compress the vibration spring 62. At this time, the extension rod 63 moves away from the dial plate 65. Then, when the vibration spring 62 continues to push the follower block 6 to reset, the extension rod 63 hits the dial plate 65, thereby driving the dial plate 65 to generate a certain vibration. Since the bottom of the bottom box 5 is attached to the main circuit board 87, when the follower block 6 switches along multiple arc grooves 59, the dial plate 65 vibrates to transmit the vibration to the main circuit board 87, thereby driving the main circuit board 87 around the drill hole to vibrate, and then the vibration is transmitted to the drill hole, accompanied by the vibration so that the debris attached to the inner wall of the drill hole falls off, and then accompanied by the suction of the exhaust duct 53 to suck and clean the waste debris in the drill hole;

[0103] S7, when drilling a hole at one point on the main circuit board 87 is completed and other points need to be drilled, the main electric push rod 28 is driven again to control the mounting frame 2 to be lifted, and the drill bit end of the electric drill 66 is separated from the drilling hole and maintained at a predetermined distance from the surface of the main circuit board 87, so that the pressure rod 72 is located at the second station. Then the first adjustment motor 24 and the second adjustment motor 33 are driven again to adjust the position of the horizontal frame 3 on the mounting frame 2 in the X-axis direction and the position of the installation box 4 on the horizontal frame 3 in the Y-axis direction, so that the electric drill 66 in the installation box 4 is positioned again at the next point to be drilled. When the new point is found and adjusted, the main electric push rod 28 is controlled again and the mounting frame 2 is driven downward, so that the electric drill 66 drills the new point on the main circuit board 87 again;

[0104] When all the drilling points on the main circuit board 87 are drilled, the main electric push rod 28 is used to drive the electric drill 66 to move upward, and the pressure rod 72 is switched from station two to station one. When the pressure rod 72 is switched from station two to station one, the main spring 71 releases the stored force, and the bottom end of the pressure rod 72 gradually separates from the top of the hole-opening platform 1, and then the pressure rod 72 moves upward synchronously with the mounting frame 2, and the bottom end of the pressure rod 72 gradually separates from the ramp block 8. When the bottom end of the pressure rod 72 is completely separated from the ramp block 8, the reset spring 84 pushes the T-bar 81 away from the main circuit board 87 and releases the clamping of the main circuit board 87. At the same time, when the pressure rod 72 moves up and leaves the top of the drilling platform 1 and the T-shaped rod 81 releases the clamping of the main circuit board 87, the draw rod 73 moves up synchronously with the pressure rod 72. As the draw rod 73 moves up, the multiple tooth blocks 75 on the draw rod 73 are sequentially embedded in the teeth of the ratchet 9 and the ratchet 9 is driven to rotate forwardly. Figure 6 As shown, when the ratchet 9 rotates forward, the ratchet 9 moves the elastic plate 92 to make the elastic plate 92 free from the locking of the ratchet 9. As the ratchet 9 rotates, the belt transmission between the two second pulleys 91 is coordinated to make the large toothed disc 93 rotate and mesh with the small toothed disc 94. The meshing between the large toothed disc 93 and the small toothed disc 94 realizes the speed change effect, and then the small toothed disc 94 rotates to make the third wedge gear 95 on its shaft mesh with the third wedge gear 95 on the change shaft 96, thereby driving the change shaft 96 to rotate, and then the change shaft 96 and the driving wheel 98 are driven by the belt between the two third pulleys 97 to make the driving wheel 98 rotate, and because the main circuit board 87 has been released from the clamping, the main circuit board 87 is driven to move to the top of the hole-opening table 1 through the rotation of the driving wheel 98 to realize the operation of transporting the main circuit board 87.

Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
