Description

Technical Field

[0001] The present invention relates to the field of PCB controlled deep drilling, and in particular to a 5G communication PCB controlled deep drilling device and process. Background Art

[0002] PCB depth-controlled drilling is a technology used to precisely control drilling depth during printed circuit board (PCB) manufacturing. Its principle is to utilize the conductive signal generated by the drill bit upon contact with the PCB surface, using this as the zero interface to drill down to a specified depth. When the drill tip contacts the copper foil, a weak current is generated. The device precisely senses this tiny current change to accurately determine the board's height and position. The device then proceeds to a pre-set drilling depth, stopping drilling when the predetermined depth is reached. Deep drilling is achieved by controlling the excess thickness of the workpiece. Excess thickness is defined as the height from the table to the drill bit's processing position. The actual drilling depth is the difference between the total board thickness and the excess thickness. A first coil is pre-placed at a predetermined location within the PCB, and a second coil is attached to the drill bit. One coil is configured as the excitation coil, and the other as the energized coil. The drill bit is controlled to drill from a predetermined drilling location on the first surface of the PCB to a predetermined position. The drill bit stops when the induced electromotive force / current detected by the sensing device exceeds a predetermined threshold.

[0003] With the advancement of technology, 5G communications are also being applied to PCB controlled depth drilling. 5G communications feature high frequencies and fast data transmission rates, placing extremely stringent demands on signal integrity. For example, in the millimeter wave band, signal transmission loss can reach 15%, resulting in signal attenuation of 7%. Controlled depth drilling requires extremely high precision. Currently, backdrill depth control accuracy can reach ±6 mils to ensure precise drilling depth, reduce signal reflections, scattering, and latency, and maintain signal quality. 5G communication PCBs are densely populated with electronic components, resulting in tight wiring space. Small-diameter controlled depth drilling is required to achieve more via connections while ensuring hole wall quality and drilling accuracy to meet the requirements of high-density interconnection.

[0004] However, when drilling holes in existing PCBs, in order to achieve electrical connections between circuit board layers or structural requirements, it is necessary to drill back and forth on both sides of the PCB. Existing PCBs are generally fixed to the processing table with tape and cannot be turned over during drilling, so the PCB is generally drilled side by side. This will cause large errors when the upper and lower holes need to be coaxially aligned, affecting the stability of subsequent circuit transmission. Therefore, a 5G communication PCB controlled deep drilling device and process are proposed. Summary of the Invention

A bearing seat is installed on the base, and each of the rotating shafts 2 is rotatably sleeved on the bearing seat.

[0015] A 5G communication PCB controlled deep drilling process includes the following steps: Step 1: First determine the thickness of the PCB to be drilled, then control the push rod motor to adjust the height of the lower clamping plate so that when the PCB is clamped between the lower and upper clamping plates, the mid-thickness plane of the PCB is coplanar with the axis of the first rotating shaft. Then control the two bases to slide closer to each other until the lower and upper clamping plates on the two bases can clamp the two edges of the PCB. Step 2: Control the two ends of the bidirectional telescopic member to retract synchronously, driving the two side slides closer to each other. Then, the leveling component acts on the lower and upper clamping plates, making them parallel to the processing plane. The PCB board clamped by the components is also parallel to the processing surface. Then, the drilling module is controlled based on G communication to drill holes in the PCB board. Step 3: When the slides on both sides are driven toward each other, the linkage assembly also drives the bevel seats on both sides to move upward, and the inclined surfaces respectively contact the front and rear ends of the PCB. This allows the PCB with front and rear position errors to be contacted by the inclined surfaces of the bevel seats until it is centered relative to the slide frame and located between the vertical surfaces of the front and rear bevel seats that are close to each other. Step 4: When the PCB needs to be turned over, the slides on both sides of the slide frame are driven away from each other, the horizontal limit of the lower and upper clamping plates by the leveling component is cancelled, and the bevel seat is moved downward. The linkage component gradually drives the ratchet upward and the ratchet is driven to rotate, so that the PCB can be turned over. Step 5: Move the two slides closer to each other again, make the PCB parallel to the processing plane through the leveling component, and use the linkage component to move the bevel seat upward again to center the PCB. During this process, the downward movement of the ratchet will no longer drive the ratchet to rotate, achieving a stable and continuous flipping operation. Step 6: When the two side slides approach each other, they can also drive the cleaning component to move upward to clean the surface of the PCB board that has been drilled and turned downward to avoid waste residue.

[0016] The beneficial effects of the present invention are: 1. The technical solution of the present invention can clamp both sides of the PCB board by cooperating with the lower clamping plates and the upper clamping plates on the two side bases, and the height of the lower clamping plates can be adjusted by the push rod motor to ensure that the middle surface of the PCB board thickness can be coplanar with the axial direction of the rotating shaft when the PCB board is clamped, which is convenient for turning the PCB board over by rotating the rotating shaft during processing. Through the leveling component, the PCB board can be limited to a horizontal state after being clamped by the lower clamping plates and the upper clamping plates to improve the processing accuracy. At the same time, the linkage component can also drive the bevel seat to move upward, so that when the leveling component levels the PCB board, the bevel seats at the front and rear ends of the PCB board can also limit it to a front-to-back centered state, which is convenient for positioning processing; 2. The technical solution of the present invention drives the two side slides to approach each other through the bidirectional telescopic member, thereby driving the leveling assembly to level the PCB board. When the two side slides are driven to approach each other, the two side bevel seats can be driven downward by the linkage assembly, and then move upward against the ratchet bar. The mounting seat is driven to rotate by engaging with the ratchet wheel, thereby achieving a 180° flip of the PCB board clamped by the lower clamping plate and the upper clamping plate. During the processing, the PCB board can be flipped at any time to perform corresponding drilling on both sides, further improving the processing accuracy. 3. The technical solution of the present invention drives the two side slides to approach each other through the bidirectional telescopic parts, thereby driving the leveling assembly to level the PCB board. When the drilling module drills the upward side of the PCB board, the linkage assembly can also drive the cleaning assembly to move upward, and the cleaning assembly can clean the side that has been drilled and turned downward, thereby avoiding the waste residue from affecting the drilling quality during the subsequent flipping process, thereby improving the drilling quality.

DETAILED DESCRIPTION

[0019] The following will be combined with the Figure 1 To the attached Figure 9 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0020] Example 1:

[0021] like Figures 1-9 As shown, the present invention discloses a 5G communication PCB controlled deep drilling equipment, including an equipment chassis 1, a drilling module 2 is installed in the equipment chassis 1, bases 5 are symmetrically slidably provided at both ends of the equipment chassis 1, each base 5 is connected to a sliding frame 7, and a rotating sleeve passing through the sliding frame 7 is provided with a rotating shaft 8, the rotating shaft 8 on both sides is connected to a mounting seat 9 on the side where the sliding frames 7 on both sides are close to each other, and a ratchet 10 is connected to the side where the sliding frames 7 on both sides are away from each other, a push rod motor 11 is connected to the mounting seat 9, and a lower clamping plate 12 is connected to the push rod motor 11, an upper clamping plate 14 is slidably provided on the lower clamping plate 12, a PCB board 48 is clamped between the lower clamping plates 12 and the upper clamping plates 14 on both sides, and a slide 17 is slidably connected to both ends of the sliding frame 7, and a leveling component is provided on the slide 17, and the leveling component is used to adjust the lower clamping plate 12 and the upper clamping plate 14 to a horizontal state; Among them, the drilling module 2 is an existing 5G communication-based setting for drilling the PCB board 48. The push rod motor 11 is a high-precision, micro-motion feeding device, which is used to adjust the position of the lower clamping plate 12 when clamping PCB boards 48 of different thicknesses, ensuring that when the PCB board 48 is clamped thereon by the upper clamping plate 14, the thickness middle surface of the PCB board 48 can be coplanar with the axial direction of the rotating shaft 8, so as to achieve that the height of the upward side of the PCB board 48 remains unchanged before and after flipping, thereby ensuring the accuracy of the drilling process; The sliding frame 7 is slidably connected with a ratchet bar 22 that engages with the ratchet 10, a two-way telescopic member 27 is installed on the base 5, and the two ends of the two-way telescopic member 27 are connected to the mounting seat 28, and the mounting seat 28 is connected to a vertical plate 29 connected to the slide 17, and both ends of the base 5 are slidably provided with an angled seat 35 that abuts against the two ends of the PCB board 48, and a linkage component is provided on the mounting seat 28. The linkage component is used to control the ratchet bar 22 and the angled seat 35 to slide in opposite directions when the two-way telescopic member 27 is extended and retracted. A cleaning component is also provided on the base 5, and the cleaning component is used to clean the downward side of the PCB board 48.

[0022] A drill bit 3 for drilling holes in the PCB board 48 is installed in the drilling module 2, and a glass door that can be opened or closed is also installed above the equipment chassis 1. Furthermore, the drilling module 2 includes a track and a linear motor that can adjust the drill bit 3 with micron-level precision in the X-axis, Y-axis and Z-axis directions to control the drill bit 3 to drill holes at any position on the PCB board 48.

[0023] A guide rail 4 is installed at the bottom of the equipment chassis 1, and the bases 5 on both sides slide symmetrically on the two ends of the guide rail 4. The base 5 is connected to a bracket 6, and a sliding frame 7 is connected to the upper end of the bracket 1 6. The base 5 is also connected to a bracket 2 26, and a two-way telescopic member 27 is installed at the upper end of the bracket 2 26. The bracket 1 6 and the bracket 2 26 are both located on the upper end surface of their respective bases 5 in the front and back center, and the bracket 1 6 is located on the side where the brackets 2 26 on both sides are close to each other.

[0024] The guide rail 4 is an existing electric guide rail, such as a screw electric guide rail, a linear roller guide rail, etc., which is convenient for the high-precision synchronous adjustment of the bases 5 on both sides to move closer or farther away from each other, so as to adjust the distance between the upper and lower clamping plates 12 and the upper clamping plate 14 of the bases 5 on both sides, so as to adapt to the clamping of PCB boards 48 of different widths. Figure 8 As shown, the lower clamping plate 12 and the upper clamping plate 14 are provided with steps on one side close to each other, which are used to limit the edges on both sides of the width direction when clamping the PCB board 48, so as to prevent left and right movement between the lower clamping plate 12 and the upper clamping plate 14 during drilling processing, thereby affecting the processing accuracy.

[0025] Bracket 1 6 is connected to the lower end of the sliding frame 7 in the center front and back, and bracket 2 26 is also mounted on the outside of the two-way telescopic member 27 in the center front and back. The two-way telescopic member 27 uses an electric cylinder, electric hydraulic cylinder, electric telescopic rod, etc. with both ends at the output end, or it can use two independent but synchronously controlled single-output electric cylinders, electric hydraulic cylinders, electric telescopic rods, etc. that are symmetrically connected.

[0026] The upper end of the lower clamping plate 12 is connected to the limit slide bar 13, and the upper clamping plate 14 is slidably sleeved on the outer side of the limit slide bar 13. The upper clamping plate 14 and the lower clamping plate 12 are connected between the upper clamping plate 14 and the lower clamping plate 12, so that under the action of the spring 15, the upper clamping plate 14 has a tendency to move closer to the lower clamping plate 12 to fit with the lower clamping plate 12 when clamping the PCB board 48.

[0027] The sliding frame 7 is connected to a sliding rail 21, and a limiting sliding frame 49 is provided on the outer sliding sleeve of the sliding rail 21. One end of the ratchet bar 22 is slidably connected to the limiting sliding frame 49 and is connected to a spring 3 50 on the inner wall of the limiting sliding frame 49, while the other end extends to the outside of the limiting sliding frame 49. The sliding frame 7 is also connected to a limiting sliding frame 23, and a ratchet block 24 is slidably connected to the limiting sliding frame 23. One end of the ratchet block 24 is in the limiting sliding frame 23 and is connected to a spring 25 on its inner wall, while the other end extends to the outside of the limiting sliding frame 23. The ratchet bar 22 and the limiting sliding frame 23 are respectively on both sides of the ratchet 10, and the ratchet block 24 is also engaged with the ratchet 10.

[0028] When the ratchet 22 moves upward, it will drive the ratchet 10, the rotating shaft 8 and the mounting seat 9 to rotate. At the same time, the rotation of the ratchet 10 will act on the ratchet block 24, so that it is pushed to slide into the limiting sliding frame 23 and compress the spring 25. When the ratchet 22 moves downward, the ratchet 22 contacts the ratchet 10, so that the ratchet 22 is pushed to slide into the limiting sliding frame 49 and compress the spring 3 50. In the process, the ratchet block 24 will also limit the rotation of the ratchet 10. The ratchet 22 moves upward to drive the ratchet 10 to rotate, while the ratchet 10 does not rotate when the ratchet 22 moves downward, so that the ratchet 10 can only be driven to rotate in one direction. This is convenient for repeatedly driving the ratchet 22 to move up and down when the PCB board 48 needs to be turned over multiple times during the drilling process. The ratchet block 24 can stably limit the ratchet 10 when the ratchet 22 moves downward, ensuring that the ratchet 10 will not reverse during the downward movement of the ratchet 22.

[0029] Example 2:

[0030] like Figures 1-9 As shown, the present invention discloses a 5G communication PCB controlled deep drilling equipment. Compared with the first embodiment, this embodiment discloses the structure of the leveling component.

[0031] The leveling assembly includes an inclined block 16, an inclined block 218, a top block 19, and a guide slide 20. The inclined block 16 is symmetrically connected to the two ends of the lower splint 12 or the upper splint 14, and is symmetrical with each other. The inclined block 218 is symmetrically connected to the upper and lower ends of the slide seats 17 at both ends of the slide frame 7 that are close to each other, and is symmetrical with each other and fits in with the corresponding inclined block 16. The top block 19 is connected to the slide seat 17, and slides through the slide frame 7 to extend to the sides of the slide frames 7 that are away from each other. The vertical plate 29 cooperates and contacts with the extended end of the top block 19. The guide slide 20 is connected to the sides of the slide frames 7 that are away from each other, and the top block 19 is slidably sleeved on the outer side of the guide slide 20.

[0032] When the two-way telescopic member 27 is controlled to contract and the slides 17 on both sides are driven to approach each other, the inclined block 2 18 can be driven to come into contact with the corresponding inclined block 1 16 on the lower clamping plate 12 or the upper clamping plate 14, so as to adjust the lower clamping plate 12 and the upper clamping plate 14 to be parallel to the sliding frame 7, thereby making the PCB board 48 parallel to the sliding frame 7 and the processing surface, which can improve the processing accuracy.

[0033] Example 3:

[0034] like Figures 1-9 As shown, the present invention discloses a 5G communication PCB controlled deep drilling equipment. Compared with the second embodiment, this embodiment discloses the structure of the linkage component.

[0035] The linkage assembly includes a rotating plate 30, a flat plate 31, an L-shaped plate 32, and a slide plate 34. The rotating plate 30 is connected to the sides of the mounting seats 28 at both ends of the same two-way telescopic member 27, and the two ends of the flat plate 31 are respectively connected to the ends of the rotating plates 30 on both sides that are close to each other, and are arranged horizontally. The upper end of the flat plate 31 cooperates and abuts against the lower end of the ratchet 22. The L-shaped plate 32 is connected to the flat plate 31. The lower end of the limiting sliding frame 49 is T-shaped. The upper end of the L-shaped plate 32 cooperates and is positioned with the T-shaped end on the lower side of the limiting sliding frame 49. The slide plate 34 is connected to the lower end of the bevel seat 35. The bevel seat 35 is rotatably connected to the mounting seat 28 on each side with a rotating plate 26.

[0036] When the two-way telescopic member 27 is extended and the two-side slides 17 are moved away from each other, the inclined block 2 18 on the slide 17 is separated from the inclined block 1 16. At the same time, the two-way telescopic member 27 will pull the flat plate 31 upward through the rotating plate 1 30, and will also push the two-side bevel seats 35 downward through the rotating plate 2 36. When the bevel seats 35 move down one end and are below the PCB board 48, the flat plate 31 will come into contact with the lower end of the limit slide frame 1 49, driving the ratchet 22 to move up, and driving the ratchet 1 through engagement. 0. The mounting seat 9 and the PCB board 48 are rotated 180 degrees and flipped over, and then the two-way telescopic member 27 contracts to drive the slides 17 on both sides to approach each other and reset, and the flipped PCB board 48 is leveled. During the process, the flat plate 31 first moves down for a while, and then the L-shaped end on the upper side of the L-shaped plate 32 and the T-shaped end at the lower end of the limit slide frame 49 are pulled to drive the ratchet bar 22 to move down, and the ratchet bar 22 can be pulled down and reset, which is convenient for multiple reciprocating up and down movements to perform multiple 180 degree flips on the PCB board 48.

[0037] The setting of the L-shaped plate 32 can prevent the flat plate 31 from contacting the limit slide frame 49 when moving upward, so that the angled seats 35 on both sides are moved downward first and then come into contact, thereby preventing the angled seats 35 from restricting the rotation of the PCB board 48.

[0038] Furthermore, when the bidirectional telescopic member 27 contracts, the ratchet 22 moves down and resets, and at this time the PCB board 48 completes the 180° flip, and then the slides 17 on both sides approach each other again, and the PCB board 48 is leveled by the leveling component, and the bevel seat 35 moves up again, which can also limit the centering of the flipped PCB board 48 again in the front and back, while facilitating the repeated flipping of the PCB board 48, ensuring the processing accuracy.

[0039] The cleaning assembly includes a tooth plate 37, a second rotating shaft 39, a small gear 40, a large gear 41, a slide 43, an electric slide 44, an electric slide 45, and an electric cleaning roller 46. The tooth plate 37 is connected to the side of the two side plates 31 away from each other, the second rotating shaft 39 is rotatably connected to the base 5, the small gear 40 is centrally mounted on the outer side of the second rotating shaft 39 and meshes with the tooth plate 37, the large gear 41 is mounted on both ends of the second rotating shaft 39, the slide 43 is slidably connected to the base 5 on both sides, the electric slide 44 is connected to the slide 43, the lower end of the electric slide 45 is slidably connected in the electric slide 44, and an electric cleaning roller 46 is installed on the upper end, the surface of the electric cleaning roller 46 fits in place with the downward side of the PCB board 48, and the two sides of the slide 43 are connected with racks 47 meshing with the large gear 41.

[0040] The setting of the cleaning component ensures that when the two-way telescopic part 27 turns over the PCB board 48, the slide 43 drives the electric slide 44, the electric slide 45, and the electric cleaning roller 46 to move downward, and will not cause any downward restriction on the rotation of the PCB board 48. After the turning over is completed, the rack 47 can be engaged with the large gear 41 to drive the electric slide 44, the electric slide 45, and the electric cleaning roller 46 to move upward again, so that the electric cleaning roller 46 and the PCB board 48 that has been drilled and turned over are cleaned downward to remove waste residue and avoid affecting the drilling quality during the subsequent turning over process.

[0041] The front and rear ends of each base 5 are connected to a slide frame 1 33, and the slide plate 34 is slidably sleeved on the outer side of the slide frame 1 33 on each side. Each base 5 is also connected to a slide frame 2 42, and the slide 43 is slidably sleeved on the outer side of each slide frame 2 42. A bearing seat 38 is installed on the base 5, and each rotating shaft 2 39 is rotatably sleeved on the bearing seat 38. This arrangement makes the sliding of the bevel seat 35 and the slide 43 more stable.

[0042] Example 4:

[0043] like Figures 1-9 As shown, the present invention discloses a 5G communication PCB controlled deep drilling process, comprising the following steps: Step 1: First, determine the thickness of the PCB board 48 to be drilled. Then, control the push rod motor 11 to adjust the height of the lower clamping plate 12 so that when the PCB board 48 is clamped between the lower clamping plate 12 and the upper clamping plate 14, the middle thickness surface of the PCB board 48 is coplanar with the axis of the rotating shaft 8. Then, control the two side bases 5 to slide closer to each other until the lower clamping plates 12 and the upper clamping plates 14 on the two side bases 5 can clamp the two side edges of the PCB board 48. Step 2: Control the two ends of the bidirectional telescopic member 27 to contract synchronously, driving the slides 17 on both sides to approach each other, and then act on the lower clamping plate 12 and the upper clamping plate 14 through the leveling component, so that the lower clamping plate 12 and the upper clamping plate 14 can be parallel to the processing plane, and the PCB board 48 clamped by the components is also parallel to the processing surface, and then control the drilling module 2 based on 5G communication to drill the PCB board 48; Step 3: When the slides 17 on both sides are driven toward each other, the linkage assembly also drives the bevel seats 35 on both sides to move upward, and the bevel surfaces respectively contact the front and rear ends of the PCB board 48. This allows the PCB board 48 with a front-to-back position error to be contacted by the bevel surfaces of the bevel seats 35 until it is centered relative to the slide frame 7 and located between the vertical surfaces of the front and rear bevel seats 35 on the side close to each other. Step 4: When the PCB 48 needs to be turned over, the slides 17 on both sides of the slide frame 7 are driven away from each other, the horizontal limit of the lower clamping plate 12 and the upper clamping plate 14 by the leveling component is cancelled, and at the same time the bevel seat 35 moves downward, and the linkage component gradually drives the ratchet 22 to move upward to interact with the ratchet 10, thereby driving the ratchet 10 to rotate, and the PCB 48 can be turned 180 degrees. Step 5: Move the two side slides 17 closer to each other again, make the PCB board 48 parallel to the processing plane through the leveling assembly, and move the bevel seat 35 upward again through the linkage assembly to center the PCB board 48. During this process, the downward movement of the ratchet bar 22 will no longer drive the ratchet wheel 10 to rotate, thus achieving a stable and continuous flipping operation. Step 6: When the slides 17 on both sides are close to each other, they can also drive the cleaning component to move upward to clean the surface of the PCB board 48 that has been drilled and turned downward to avoid waste residue.
