Description

Technical Field

[0001] This invention relates to the field of PCB board processing technology, specifically to a short slot hole processing device for PCB boards that prevents misalignment. Background Technology

[0002] A PCB, or Printed Circuit Board, is an assembly board with mounting holes, connecting wires, and pads on an insulating substrate. It is used to realize electrical connections between electronic components and is known as the "mother of electronic products." Its principle is to use the insulating material of the board base to isolate the conductive copper foil layer on the surface, so that the current flows through various components along a pre-designed route to complete functions such as work, amplification, attenuation, modulation, demodulation, and encoding. Short slots on PCBs generally refer to elliptical slots with a slot length less than or equal to twice the slot width. They are irregularly shaped drill holes. When processing short slots on PCBs, a drill bit is usually used to drill multiple times to gradually form elliptical slots.

[0003] Since the short slots on a PCB board need to be gradually formed into elliptical short slots through multiple circular drilling, the short slots on the PCB board are subject to vibration or shaking caused by external forces during processing, which causes the PCB board to continuously shift slightly, affecting the processing accuracy. Therefore, we have proposed a PCB board short slot processing equipment to prevent shifting. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a PCB board short slot hole processing equipment for preventing displacement, including a base, an anti-displacement clamping device fixedly connected to the top of the base, a robotic arm fixedly connected to the top of the base, an electric drill bit rotatably connected to the inner side of the robotic arm through a rotating bolt, and a cleaning device sleeved and fixedly connected to the outer side of the electric drill bit.

[0005] The anti-deviation clamping device includes a fixed square plate, and an electric push rod is fixedly connected to the bottom of the fixed square plate. The drive shaft of the electric push rod passes through the fixed square plate and is fixedly connected to a clamping plate. By setting a hollow area between the fixed square plate and the clamping plate, it is easy to discharge the debris to the outside. This prevents the cleaning device from pushing the debris between the fixed square plate and the clamping plate during drilling, which would accumulate and affect the subsequent placement of the PCB board. A square rubber pad is fixedly connected to the bottom of the clamping plate. The square rubber pad provides elastic clamping and fixation to the board body, and its rubber surface increases the static friction of the board body. This prevents the board body from being slightly deviated due to vibration or shaking during drilling, which would affect the processing accuracy of the short slots.

[0006] Four anti-deviation clamping devices are provided, and the four anti-deviation clamping devices are symmetrically distributed on the base. The bottom of the electric push rod is fixedly connected to the top of the base.

[0007] The bottom of the clamping plate is fixedly connected to a bottom through rod. By setting the bottom through rod at the two adjacent corners of the fixed square plate near the arc-shaped through plate, the PCB board is blocked and limited to prevent the PCB board placed on the fixed square plate from shifting too much due to large external forces and detaching from the fixed square plate. The top of the fixed square plate is fixedly connected to an arc-shaped through plate near the drive shaft of the electric push rod. By setting the arc-shaped through plate through the clamping plate at the top of the fixed square plate, the drive shaft of the electric push rod is covered and protected at all times, preventing the debris pushed by the cleaning from accumulating and adhering to the drive shaft of the electric push rod and affecting the extension and retraction effect of the drive shaft. The bottom of the fixed square plate is fixedly connected to a bottom support rod.

[0008] The bottom of the bottom through rod passes through the fixed square plate and is slidably connected to the fixed square plate; the top of the arc-shaped through plate passes through the pressure plate and is slidably connected to the pressure plate.

[0009] The bottom of the bottom support rod is fixedly connected to the top of the base. Multiple bottom through rods are provided, and the multiple bottom through rods are respectively distributed on the bottom of the pressing plate near the two outer sides adjacent to the arc-shaped through plate.

[0010] Furthermore, the cleaning device includes an adjustment mechanism. A rounded-corner block is fixedly connected to the bottom of the adjustment mechanism. By setting the rounded-corner block with a smooth, rounded bottom surface to maintain smooth contact with the top of the board, friction is reduced. This prevents the large contact area of ​​the block, which is constantly in pressure contact with the top of the board, from gradually damaging the board due to friction and affecting its performance. A bottom-mounted brush is fixedly connected to the bottom of the rounded-corner block. The rotating bottom-mounted brush cleans dust and processing debris from the board surface, preventing debris and dust generated during repeated circular drilling from falling into the short slots and affecting the processing effect. An inner ring block is rotatably connected to one side of the rounded-corner block. An internal brush is fixedly connected to the inner side of the inner ring block. When the drill bit rotates, the internal brush on the inner side of the inner ring block is constantly in contact with the drill bit surface and cleans the drill bit. The surface is cleaned by friction to prevent excessive dust and debris from accumulating on the drill bit surface after prolonged use, which would affect the subsequent drilling effect. A T-shaped groove is provided on the outer side of the inner ring block, and a T-shaped arc block is rotatably connected to the inner wall of the T-shaped groove. By providing a T-shaped groove on the outer side of the inner ring block and rotating it with the T-shaped arc block, the inner ring block will not rotate with the T-shaped arc block. This prevents the inner ring block from rotating with the T-shaped arc block at high speed when the rounded bottom block drives it, making it difficult to efficiently clean the drill bit. The adjustment mechanism is sleeved on the electric drill bit and fixedly connected to it. Three rounded bottom blocks are provided, and the three rounded bottom blocks are circumferentially distributed at the bottom of the adjustment mechanism. Three T-shaped arc blocks are provided, and the three T-shaped arc blocks are circumferentially distributed on the inner wall of the T-shaped groove. One side of the T-shaped arc block is fixedly connected to one side of the rounded bottom block.

[0011] Furthermore, the adjustment mechanism includes an annular sleeve block, with an outer corner block fixedly connected to its outer side. A return spring is fixedly connected to the bottom of the outer corner block. The return spring, positioned between the outer corner block and the rounded bottom block, adapts to the movement of the drill bit, preventing the rounded bottom block from being difficult to adjust as the drill bit moves up and down, thus affecting the drilling depth. A corrugated ring is fixedly connected to the bottom of the outer corner block. This corrugated ring covers the return spring, preventing dust and debris removed by the bottom and internal brushes from splashing and adhering to the return spring, thus affecting its extension and retraction. A through-rod is slidably connected to the bottom of the outer corner block. A through-rod, penetrating the outer corner block, is provided at the top of the rounded bottom block. The rounded corner block with elastic connection is moved and limited to prevent it from tilting outward due to centrifugal force, thus affecting its use. The diameter of the top-penetrating rod is set to be the same as the inner diameter of the return spring to internally support and stabilize the shape of the return spring, preventing it from gradually twisting and misaligning due to centrifugal force as the return spring rotates with the outer corner block and the rounded corner block, thus affecting its performance. The annular sleeve is fitted onto the electric drill bit and fixedly connected to it. There are three outer corner blocks, which are distributed circumferentially on the outside of the annular sleeve. The bottom of the return spring is fixedly connected to the top of the rounded corner block, the bottom of the wave-shaped ring is fixedly connected to the top of the rounded corner block, and the bottom of the top-penetrating rod is fixedly connected to the top of the rounded corner block.

[0012] This invention provides a PCB board short slot hole processing device to prevent misalignment. It has the following beneficial effects:

[0013] 1. This anti-offset PCB board short slot processing equipment uses square rubber pads to elastically press and fix the board body, and the rubber surface increases the static friction of the board body to prevent the board body from being slightly offset due to vibration or shaking during drilling, which would affect the processing accuracy of the short slot. The rotating bottom brush cleans the dust and processing debris on the surface of the board body, preventing debris and dust generated during multiple circular drilling processes from falling into the short slot and affecting the processing effect. A reset spring is set between the outer corner block and the rounded bottom block to adapt to the movement of the drill bit and adjust the extension and retraction, preventing the rounded bottom block from being difficult to adjust when moving up and down with the drill bit, which would affect the drilling depth of the drill bit.

[0014] 2. This anti-displacement PCB board short slot processing equipment is equipped with an anti-displacement clamping device. A square rubber pad elastically clamps and fixes the board, increasing static friction to prevent slight displacement during drilling due to vibration or shaking, which could affect the processing accuracy of the short slots. An open area between the fixed square plate and the clamping plate facilitates the removal of debris, preventing it from accumulating between the fixed square plate and the clamping plate and affecting subsequent PCB board placement. An arc-shaped through-plate at the top of the fixed square plate covers and protects the drive shaft of the electric push rod, preventing debris from accumulating and affecting its extension and retraction. Bottom through-bars near the two adjacent corners of the arc-shaped through-plate limit the PCB board, preventing excessive displacement and detachment due to external forces.

[0015] 3. This anti-deviation PCB board short slot processing equipment is equipped with a cleaning device. The rotating bottom brush cleans the dust and processing debris from the board surface, preventing debris and dust generated during multiple circular drilling operations from falling into the short slots and affecting the processing effect. The rounded bottom block with a smooth, rounded corner surface keeps it in smooth contact with the top of the board, reducing friction and preventing the large contact area of ​​the bottom block from gradually damaging the board due to friction and affecting its performance. The T-shaped groove on the outside of the inner ring block, which rotates with the T-shaped arc block, prevents the inner ring block from rotating with the T-shaped arc block. This prevents the inner ring block from rotating with the T-shaped arc block at high speed when the rounded bottom block drives the T-shaped arc block, making it difficult to efficiently clean the drill bit. When the drill bit rotates, the built-in brush on the inside of the inner ring block keeps in constant contact with the drill bit surface and cleans it by friction, preventing the drill bit surface from accumulating too much dust and debris after long-term use, which would affect the subsequent drilling effect.

[0016] 4. This anti-displacement PCB board short slot processing equipment is equipped with an adjustment mechanism. A return spring is installed between the outer corner block and the rounded bottom block to adapt to the movement of the drill bit and adjust its extension and retraction. This prevents the rounded bottom block from being difficult to adjust when moving up and down with the drill bit, thus affecting the drilling depth. A wave-shaped ring is installed on the outside of the return spring to cover it, preventing dust and debris cleaned by the bottom brush and the internal brush from splashing and adhering to the return spring and affecting its extension and retraction. A top-penetrating rod is installed on the top of the rounded bottom block, penetrating the outer corner block, to limit the movement of the elastically connected rounded bottom block and prevent the rounded bottom block, which is elastically connected by the return spring, from tilting and shifting outward due to centrifugal force, thus affecting its use. The diameter of the top-penetrating rod is set to be the same as the inner diameter of the return spring to internally support and stabilize the shape of the return spring, preventing the return spring from gradually twisting and misaligning due to centrifugal force as it rotates with the outer corner block and the rounded bottom block, thus affecting its performance.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-4 The present invention provides a PCB board short slot hole processing equipment for preventing displacement, including a base 1, an anti-displacement clamping device 2 fixedly connected to the top of the base 1, a robotic arm 3 fixedly connected to the top of the base 1, an electric drill bit 4 rotatably connected to the inner side of the robotic arm 3 through a rotating bolt, and a cleaning device 5 sleeved and fixedly connected to the outer side of the electric drill bit 4.

[0028] The anti-deviation clamping device 2 includes a fixed square plate 201, an electric push rod 202 is fixedly connected to the bottom of the fixed square plate 201, the drive shaft of the electric push rod 202 passes through the fixed square plate 201 and is fixedly connected to a clamping plate 203, and a square rubber pad 204 is fixedly connected to the bottom of the clamping plate 203.

[0029] Four anti-deviation clamping devices 2 are provided, and the four anti-deviation clamping devices 2 are symmetrically distributed on the base 1. The bottom of the electric push rod 202 is fixedly connected to the top of the base 1.

[0030] The bottom of the pressing plate 203 is fixedly connected to the bottom through rod 205, the top of the fixed square plate 201 near the drive shaft of the electric push rod 202 is fixedly connected to the arc-shaped through plate 206, and the bottom of the fixed square plate 201 is fixedly connected to the bottom support rod 207.

[0031] The bottom of the bottom through rod 205 passes through the fixed square plate 201 and is slidably connected to the fixed square plate 201; the top of the arc-shaped through plate 206 passes through the pressing plate 203 and is slidably connected to the pressing plate 203.

[0032] The bottom of the bottom support rod 207 is fixedly connected to the top of the base 1. Multiple bottom through rods 205 are provided, and the multiple bottom through rods 205 are distributed on the bottom of the clamping plate 203 near the two outer sides adjacent to the arc-shaped through plate 206. In use, the lower pad, PCB substrate and upper cover are placed on the four anti-displacement clamping devices 2 in sequence. The anti-displacement clamping devices 2 are used to elastically clamp and fix the four corners of the board to prevent displacement. After the board is fixed, the robotic arm 3 drives the electric drill bit 4 to perform multiple drilling operations on the designated position of the PCB substrate. When the electric drill bit 4 rotates, it will drive the outer cleaning device 5 to rotate together to clean the surrounding area of ​​the drill hole and the drill bit residue. The four corners of the lower pad, PCB substrate and upper cover are placed on the fixed square plate 201 in sequence. Then, the electric push rod 202 drives the clamping plate 203 to move down. The downward movement of the clamping plate 203 drives the square rubber pad at the bottom. When the 204 moves down together to contact the upper cover plate, the board body is elastically pressed to prevent displacement. The board body is elastically pressed by the square rubber pad 204 and its rubber surface increases the static friction of the board body. The space between the fixed square plate 201 and the pressing plate 203 is set as a hollow area to facilitate the discharge of debris to the outside. The arc-shaped through plate 206 that passes through the pressing plate 203 is set at the top of the fixed square plate 201 to cover and protect the drive shaft of the electric push rod 202. The bottom through rod 205 is set at the two adjacent corners of the fixed square plate 201 near the arc-shaped through plate 206 to block and limit the PCB board. After the PCB board is processed, the pressing plate 203 is pushed up by the electric push rod 202 and the bottom through rod 205 is moved up together. When the bottom through rod 205 moves up to the position where the top of the fixed square plate 201 is above the PCB board, the processed PCB board can be removed.

[0033] Please see Figures 1-8 This invention provides a PCB board short slot processing device to prevent misalignment: the cleaning device 5 includes an adjusting mechanism 501, a rounded bottom block 502 fixedly connected to the bottom of the adjusting mechanism 501, a bottom-mounted brush 503 fixedly connected to the bottom of the rounded bottom block 502, an inner ring block 504 rotatably connected to one side of the rounded bottom block 502, a built-in brush 505 fixedly connected to the inner side of the inner ring block 504, and a T-shaped annular groove 506 formed on the outer side of the inner ring block 504. A T-shaped arc block 507 is rotatably connected to the inner wall of the T-shaped annular groove 506. The adjusting mechanism 501 is sleeved on the electric drill bit 4 and fixedly connected to the electric drill bit 4. Three rounded bottom blocks 502 are provided, and the three rounded bottom blocks 502 are distributed in a circle at the bottom of the adjusting mechanism 501. Three T-shaped arc blocks 507 are provided, and the three T-shaped arc blocks 507 are distributed in a circle on the inner wall of the T-shaped annular groove 506. One side of the T-shaped arc block 507 is fixedly connected to one side of the rounded bottom block 502.

[0034] The adjusting mechanism 501 includes an annular sleeve 5011. An outer corner block 5012 is fixedly connected to the outer side of the annular sleeve 5011. A return spring 5013 is fixedly connected to the bottom of the outer corner block 5012. A wave-shaped ring plate 5014 is fixedly connected to the bottom of the outer corner block 5012. A through-rod 5015 is slidably connected to the bottom of the outer corner block 5012. The annular sleeve 5011 is fitted onto the electric drill bit 4 and fixedly connected to it. Three outer corner blocks 5012 are provided, and the three outer corner blocks 5012 are circumferentially distributed outside the annular sleeve 5011. The bottom of the return spring 5013 is fixedly connected to the top of the rounded corner block 502, and the bottom of the wave-shaped ring plate 5014 is fixedly connected to the top of the rounded corner block 502. The bottom of the top-through rod 5015 is fixedly connected to the top of the rounded bottom block 502. During use, when the drill bit rotates, it drives the outer adjusting mechanism 501 to rotate as well. The rotation of the adjusting mechanism 501 causes the rounded bottom block 502 to rotate around the inner ring block 504. The rotation of the rounded bottom block 502 causes the bottom-mounted brush 503 and the T-shaped arc block 507 on one side to rotate around the inner ring block 504. The rotation of the bottom-mounted brush 503 cleans the dust and processing debris from the board surface. When the drill bit moves down to drill a hole in the board, it drives the adjusting mechanism 501 and the rounded bottom block 502 to move down together. After the rounded bottom block 502 moves down to contact the top of the board, it remains in contact with the top of the board under the adaptive extension and retraction adjustment of the adjusting mechanism 501. By setting the rounded bottom block 502 with a smooth rounded corner surface to be in constant smooth contact with the top of the plate, friction is reduced. A T-shaped annular groove 506 on the outer side of the inner ring block 504, which rotates in conjunction with the T-shaped arc block 507, prevents the inner ring block 504 from rotating with the T-shaped arc block 507. When the drill bit rotates, the built-in brush 505 on the inner side of the inner ring block 504 is constantly in contact with the drill bit surface and performs friction cleaning. When the drill bit moves downwards to drill, it causes the annular sleeve block 5011, the outer connecting corner block 5012, and the rounded bottom block 502 to move downwards together. After the rounded bottom block 502 moves down to contact the top of the plate, it compresses the top return spring 5013. At the same time, the rounded bottom block 502 drives the top to pass through the outer connecting corner block 5012. The top-through rod 5015 gradually moves upward. When the drill bit finishes processing and drives the annular sleeve block 5011 to move upward, the return spring 5013 returns to its original position through the stretching force. The return spring 5013 is set between the outer corner block 5012 and the rounded bottom block 502 to adapt to the movement of the drill bit and adjust its extension and retraction. The return spring 5013 is wrapped and covered by a wave-shaped ring plate 5014 on the outside of the return spring 5013. The rounded bottom block 502 is elastically connected and its movement is limited by the top-through rod 5015 that passes through the outer corner block 5012. The return spring 5013 is internally supported and stabilized by setting the diameter of the top-through rod 5015 to be the same as the inner diameter of the return spring 5013.

[0035] In operation, the lower pad, PCB substrate, and upper cover are placed sequentially on four anti-displacement clamping devices 2. The anti-displacement clamping devices 2 elastically clamp the four corners of the board to prevent displacement. After the board is fixed, the robotic arm 3 drives the electric drill bit 4 to perform multiple drilling operations on the designated positions of the PCB substrate. When the electric drill bit 4 rotates, it drives the outer cleaning device 5 to rotate as well to clean the surrounding area of ​​the drill holes and the drill bit debris. The four corners of the lower pad, PCB substrate, and upper cover are placed sequentially on the fixed square plate 201. Then, the electric push rod 202 drives the clamping plate 203 to move down. The downward movement of the clamping plate 203 causes the bottom square rubber pad 204 to move down together until it contacts the upper cover plate, which elastically clamps the board. The PCB board is secured by a compression-type anti-displacement device. A square rubber pad 204 elastically compresses and secures the board, increasing static friction through its rubber surface. An open area between the fixing square plate 201 and the compression plate 203 facilitates the removal of debris. An arc-shaped through-plate 206, penetrating the compression plate 203, continuously protects the drive shaft of the electric push rod 202. Bottom through-rods 205, positioned at adjacent corners of the fixing square plate 201 near the arc-shaped through-plate 206, provide resistance and limit the PCB board's movement. After PCB board processing, the electric push rod 202 pushes the compression plate 203 upwards, moving the bottom through-rods 205 upwards as well. The bottom through-rods 205 move to the top of the fixing square plate 201. Positioned above the PCB board, the processed PCB board can be removed. When the drill bit rotates, it drives the outer adjusting mechanism 501 to rotate as well. The rotation of the adjusting mechanism 501 causes the bottom rounded corner block 502 to rotate around the inner ring block 504. The rotation of the rounded corner block 502 causes the bottom-mounted brush 503 and the T-shaped arc block 507 on one side to rotate around the inner ring block 504. The rotation of the bottom-mounted brush 503 cleans dust and processing debris from the board surface. When the drill bit moves down to drill a hole in the board, it drives the adjusting mechanism 501 and the rounded corner block 502 down together. After the rounded corner block 502 reaches contact with the top of the board, it remains in contact with the top of the board under the adaptive extension and retraction adjustment of the adjusting mechanism 501. By setting the bottom to be light-sensitive... The rounded corner block 502 of the smooth, rounded corner surface maintains smooth contact with the top of the plate, reducing friction. A T-shaped annular groove 506 on the outer side of the inner ring block 504, which rotates in conjunction with the T-shaped arc block 507, prevents the inner ring block 504 from rotating with the T-shaped arc block 507. When the drill bit rotates, the built-in brush 505 on the inner side of the inner ring block 504 constantly contacts the drill bit surface and cleans it. As the drill bit moves downwards to drill, it causes the annular sleeve block 5011, the outer connecting corner block 5012, and the rounded corner block 502 to move downwards together. Once the rounded corner block 502 reaches contact with the top of the plate, it compresses the top return spring 5013. Simultaneously, the rounded corner block 502 causes the top through-rod 5015, which passes through the outer connecting corner block 5012, to gradually move upwards.When the drill bit finishes machining and moves the annular sleeve 5011 upwards, the return spring 5013 returns to its original position through extension force. The return spring 5013 is positioned between the outer corner block 5012 and the rounded bottom block 502 to adapt to the movement of the drill bit and provide extension / retraction adjustment. A wave-shaped ring 5014 is provided on the outside of the return spring 5013 to cover it. A through-rod 5015 is provided at the top of the rounded bottom block 502, penetrating the outer corner block 5012, to limit the movement of the elastically connected rounded bottom block 502. The diameter of the through-rod 5015 is set to be the same as the inner diameter of the return spring 5013 to internally support and stabilize its shape.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
