Description

Technical Field

[0001] This utility model relates to the field of PCB board production technology design, and in particular to a PCB partition board through-hole processing fixture and drilling device. Background Technology

[0002] In the electroless gold plating process of PCB manufacturing, 2mm diameter copper wires are used to connect the PCB boards. Teflon separators connect the boards. These separators are comb-shaped, with several evenly arranged baffles at one end. Gaps exist between the baffles, and a 3mm diameter through-hole is drilled at the top of each baffle at a relatively opposite position for the copper wire connection. Specifically, for example... Figure 1 As shown, multiple PCBs are set on a PCB partition, and the edge holes of the PCBs correspond to the through holes processed on the PCB partition. Copper wires can be passed through the through holes for gold plating.

[0003] The total length of the deep hole formed by all through-holes is approximately 260mm. Current drilling equipment often performs poorly in machining through-holes in PCB partitions. First, due to the inherent properties of Teflon material, it is prone to deformation and deviation during machining, making it difficult to ensure the perpendicularity of the hole. Second, three-axis CNC machine tools are also difficult to complete machining tasks with such special shapes and depth requirements because the machining stroke and machining angle of three-axis CNC machine tools are limited, making it impossible to machine through-holes with such length and precision requirements. In addition, since Teflon is an insulating material that is resistant to high temperatures and corrosion, conventional electrical discharge machining (EDM) methods are not applicable here. The principle of EDM is based on electrical discharge corrosion, and insulating materials cannot conduct electricity. Although gun drilling can achieve a certain depth and precision requirements, its cost is too high, which would significantly increase costs for large-scale production. Common laser drilling technology is also difficult to effectively machine a 260mm long deep hole.

[0004] The aforementioned shortcomings of existing technologies severely restrict the through-hole processing of PCB partition boards. Therefore, there is an urgent need for a through-hole processing tool for PCB partition boards that can balance drilling efficiency and quality, reduce production costs, and enhance product competitiveness. Summary of the Invention

[0005] In view of this, this application aims to at least partially solve the problems in the related technology. One of the purposes of this application is to provide a PCB partition board through hole processing fixture, which can ensure the accuracy of the drill bit position during the drilling process while fixing the PCB partition board, so that the drilled through hole has high precision and low manufacturing cost.

[0006] This application provides a PCB partition board through-hole processing fixture, comprising: a fixing component for fixing the PCB partition board; the fixing component is provided with at least one guide hole; the diameter of the guide hole is larger than the diameter of the through hole in the PCB partition board; the guide hole is aligned with all preset drilling positions and the guide hole is provided at the front end of the first preset drilling position.

[0007] Specifically, the PCB partition is secured with fixing components to ensure its stable position and prevent displacement of the drilled through-holes. In practice, the number of guide holes is one more than the number of baffles, allowing the drill bit to pass through the guide holes sequentially to drill through the baffles and exit from the last guide hole, with the guide holes aligned with the preset drilling positions on the PCB partition. A suitable electric drill is selected, and a 300mm long twist drill bit is mounted on it. The diameter of the twist drill bit is slightly smaller than the 3mm diameter of the through-hole, as the diameter of the through-hole is usually slightly larger than the drill bit diameter due to factors such as friction, heat, and vibration. The fixture is made of stainless steel to ensure its stability and durability during processing; the twist drill is made of carbon steel to reduce wear on the fixture while achieving the drilling operation. The first guide hole is located at the front of the first preset drilling position. After passing the twist drill bit through the first guide hole, drill holes in the PCB partition. The drill bit then drills through all the preset drilling positions of all the partitions in sequence. Coolant can be added during the drilling process to prevent the twist drill from overheating and wearing down due to excessive drilling speed. After drilling all the partitions, remove the processed PCB partition from the fixing assembly and continue to the next operation.

[0008] This fixture assists an electric drill in drilling holes in PCB partitions, producing high-precision through holes. Through the fixing of the fixing components and the guidance of the guide holes, the drill bit's position is ensured to be accurate, enabling effective machining of 260mm deep holes on PCB partitions with high drilling precision. Compared to expensive professional deep-hole machining tools, this fixture has low manufacturing costs, is made of high-strength metal materials, and has high market application and promotion value.

[0009] In a preferred embodiment of this invention, the diameter of the guide hole is 0.1 mm larger than the diameter of the through hole in the PCB partition plate.

[0010] The diameter of the guide hole is slightly larger than the diameter of the through hole in the PCB partition to ensure that the twist drill can pass through smoothly while providing sufficient guidance.

[0011] In a preferred embodiment of this invention, the fixing component includes M fastening members and limiting members for fixing the fastening members; every two opposing fastening members form a set of openable clamping members; the guide hole is located on the clamping member; the clamping member is provided with a limiting groove for placing the PCB partition plate; the PCB partition plate abuts against the limiting groove; M is an even number greater than 0.

[0012] In practice, two fastening components are typically used. After the clamping mechanism formed by the two fastening components is opened, the PCB partition is placed in the limiting groove, abutting against the groove to prevent misalignment. Then, the clamping mechanism is closed, and the limiting component secures it, preventing displacement during drilling. A twist drill is then passed through the guide hole to drill holes in the baffles on the PCB partition. The combination of the clamping and limiting components provides excellent fixation for the PCB partition, ensuring its stable position and preventing misalignment of the drilled through-holes.

[0013] In a preferred embodiment of this invention, a plurality of limiting blocks are evenly arranged on the fastening member; the gaps between the limiting blocks and the baffles correspond one-to-one; the limiting blocks abut against the baffles at their front ends and are arranged in a staggered manner.

[0014] After the PCB partition is placed in the limiting groove, the limiting block abuts against the front baffle and is staggered, so that the limiting block at the rear end can exert a force on the front baffle when drilling, preventing deformation or deviation of the Teflon material during processing due to its own characteristics, which would affect the accuracy of the drilled through hole.

[0015] In a preferred embodiment of this invention, the gap between the limiting blocks is x, and the gap between the baffles is y, with x being 0.07~0.1mm larger than y.

[0016] The gap between the limiting blocks is 0.07~0.1mm larger than the gap between the baffles, which allows for a certain amount of assembly space. During the drilling process, the two can fit tightly together, so that the limiting blocks can limit the baffles and prevent the baffles from deforming during the processing, thus affecting the accuracy of the through hole.

[0017] In a preferred embodiment of this invention, the limiting block is provided with a guide groove; two opposing guide grooves on each set of clamping members form a guide hole.

[0018] After placing the PCB separator in the limiting groove, close the clamping device. The two guide grooves in opposite positions form a guide hole. Start the electric drill and let the twist drill bit gradually feed along the guide hole to ensure that the guide hole can play an effective guiding role throughout the entire processing. After drilling is completed, simply open the clamping device to separate the guide hole into a guide groove, reduce the resistance of the drill bit withdrawal, and improve the drilling efficiency.

[0019] In a preferred embodiment of this invention, the limiting member includes a bench vise; the bench vise is used to fix the clamping member.

[0020] When drilling, use a vise to hold the clamping parts of the fitted PCB partition board in place to ensure its stable position before drilling to improve drilling accuracy.

[0021] The function of the limiting component is to fix the clamping component, prevent it from shifting during drilling, and ensure its position is stable. For its specific structure, you can refer to other existing structures, such as slots and buckle assemblies set on the worktable.

[0022] In a preferred embodiment of this invention, the surface of the fastening element is provided with chip-receiving grooves that correspond one-to-one with the guide holes; the chip-receiving grooves are connected to the guide grooves.

[0023] After machining to a certain depth, drill chips may not be easily removed in time. To ensure machining quality, a chip groove is installed above the guide hole. This allows the drill chips to enter the chip groove through the guide of the twist drill and then be discharged from the groove to the outside. This eliminates the need for repeated pulling and tucking, preventing drill chips from affecting the drilling operation and improving drilling accuracy. After machining, the machined Teflon material is removed from the fixture, and the drill chips in the chip groove are cleaned. Teflon material has good non-stick properties, making it easy to clean. Quality inspection is then performed. If the perpendicularity or dimensional accuracy of the hole does not meet the requirements, the cause needs to be analyzed, machining parameters adjusted, or the fixture design improved to avoid similar problems in subsequent machining.

[0024] In a preferred embodiment of this invention, the guide hole has a chamfered edge.

[0025] The chamfer helps guide the twist drill bit into the pilot hole, ensuring that the twist drill bits can smoothly enter the pilot hole in sequence, thus improving drilling efficiency.

[0026] The second objective of this application is to provide a PCB partition board drilling device, including the aforementioned PCB partition board through-hole processing fixture.

[0027] Specifically, according to the predetermined drilling position and angle, a series of guide holes and chip grooves are precisely machined on the fixture. By selecting a suitable electric drill and drill bit, the PCB partition board embedded in the fixture can be drilled. During the processing, the limiting block reduces the deformation rate of the baffle. The setting of several guide holes and chip grooves ensures the angle and smooth movement of deep hole processing, which can effectively process deep holes with a length of 260mm, and improve the drilling accuracy of the PCB partition board drilling device.

[0028] The fixture assists the electric drill in drilling PCB partitions, producing high-precision through holes. Through the fixing components and guide holes, the drill bit's position is ensured to be accurate, enabling the effective machining of holes up to 260mm in length, thus improving the drilling accuracy of the drilling device. Furthermore, compared to gun drilling, the fixture in the drilling device is made of high-strength metal, reducing the cost of the PCB partition drilling device and increasing its market competitiveness.

[0029] This utility model has at least the following beneficial effects:

[0030] This fixture assists an electric drill in drilling holes in PCB partitions, producing high-precision through holes. Through the fixing of the fixing components and the guidance of the guide holes, the drill bit's position is ensured to be accurate, enabling the effective processing of 260mm deep holes in the PCB partitions with high drilling precision. Compared to expensive professional deep-hole machining tools, this fixture has low manufacturing costs, is made of high-strength metal materials, and has high market application and promotion value.

[0046] Specifically, the PCB partition plate 20 is fixed in place with a fixing component to ensure its stable position and prevent the drilled through-hole from shifting. In this embodiment, the number of guide holes is one more than the number of baffles 22, allowing the drill bit to pass through the guide holes sequentially to drill through the baffles 22 and exit from the last guide hole.

The guide hole at the front end of the first preset drilling position 21 is the first guide hole. After passing the twist drill bit through the first guide hole, the PCB partition plate 20 is drilled. The drill bit drills through all the preset drilling positions 21 of all the baffles 22 in sequence. Coolant can be added during the drilling process to prevent the twist drill from being worn due to overheating and friction caused by excessive drilling speed. After drilling all the baffles 22 is completed, the processed PCB partition plate 20 is removed from the fixing assembly to continue to the next operation.

[0047] This fixture assists an electric drill in drilling holes in a PCB partition plate 20, producing high-precision through holes. Through the fixing of the fixing components and the guidance of the guide holes, the drill bit's position is ensured to be accurate, enabling effective processing of deep holes up to 260mm in length on the PCB partition plate with high drilling precision. Compared to expensive professional deep-hole machining tools, this fixture has low manufacturing costs, is made of high-strength metal materials, and has high market application and promotion value.

[0048] Preferably, the diameter of the guide hole is 0.1 mm larger than the diameter of the through hole of the PCB separator 20.

[0049] The diameter of the guide hole is slightly larger than the diameter of the 20 through hole in the PCB separator to ensure that the twist drill can pass through smoothly while providing sufficient guidance.

[0050] Preferably, the guide hole has a chamfer of 13 on its side.

[0051] The 13-degree chamfer guides the twist drill bit into the pilot hole, ensuring that the twist drill bit can smoothly enter the pilot hole in sequence, thus improving drilling efficiency.

[0052] Example 2

[0053] like Figures 1-3 As shown, this embodiment provides a PCB partition plate through-hole processing fixture, including: a fixing component for fixing the PCB partition plate 20; the fixing component is provided with at least one guide hole; the diameter of the guide hole is larger than the diameter of the through hole of the PCB partition plate 20; the guide hole is aligned with all preset drilling positions 21 and the guide hole is provided at the front end of the first preset drilling position 21.

[0054] Specifically, the PCB partition plate 20 is fixed in place with a fixing component to ensure its stable position and prevent the drilled through-hole from deviating. In this embodiment, the number of guide holes is equal to the number of baffles 22, allowing the drill bit to pass through the guide holes sequentially to drill holes in the baffles 22. The guide holes are aligned with the preset drilling positions 21 on the PCB partition plate 20. A suitable electric drill is selected, and a 300mm long twist drill bit is mounted on the drill. The diameter of the twist drill bit is slightly smaller than the 3mm diameter of the through-hole. Due to factors such as friction, heat, and vibration, the diameter of the through-hole is usually slightly larger than the diameter of the drill bit. The fixture is made of stainless steel to ensure its stability and durability during processing; the twist drill is made of carbon steel to reduce wear on the fixture while achieving the drilling operation.

The drill bit drills through all the preset drilling positions 21 of all the baffles 22 in sequence. Coolant can be added during the drilling process to prevent the twist drill from being worn due to overheating and friction caused by excessive drilling speed. After drilling all the baffles 22 is completed, the processed PCB partition plate 20 is removed from the fixing assembly to continue to the next operation.

[0055] This fixture assists an electric drill in drilling holes in the PCB partition board 20, producing high-precision through holes. Through the fixing of the fixing components and the guidance of the guide holes, the drill bit's position is ensured to be accurate, enabling effective machining of deep holes up to 260mm in length with high drilling precision. Compared to expensive professional deep-hole machining tools, this fixture has low manufacturing costs, is made of high-strength metal materials, and has high market application and promotion value.

[0056] Preferably, the fixing assembly includes M fasteners 10 and limiting members for fixing the fasteners 10; every two opposing fasteners 10 form a set of openable clamping members; the guide hole is located on the clamping member; the clamping member is provided with a limiting groove for placing the PCB partition plate 20; the PCB partition plate 20 abuts against the limiting groove; M is an even number greater than 0.

[0057] In this embodiment, four fastening members 10 are provided. After the clamping member formed by the four fastening members 10 is opened, the PCB partition plate 20 is placed in the limiting groove, and the PCB partition plate 20 abuts against the limiting groove to prevent the PCB partition plate 20 from deviating within the limiting groove. Then, the clamping member is closed, and the limiting member is used to fix the clamping member in place to prevent displacement of the clamping member during drilling. Then, the twist drill is allowed to pass through the guide hole to drill holes in the baffles 22 on the PCB partition plate 20 in sequence. The combination of the clamping member and the limiting member has a good fixing effect on the PCB partition plate 20, ensuring its positional stability and preventing the drilled through holes from deviating.

[0058] Preferably, a plurality of limiting blocks 14 are evenly provided on the fastening member 10; the gaps between the limiting blocks 14 and the baffles 22 correspond one-to-one; the limiting blocks 14 abut against the baffles 22 at their front ends and are staggered.

[0059] After the PCB separator 20 is placed in the limiting groove, the limiting block 14 abuts against the front baffle 22 and is staggered, so that the limiting block 14 at the rear end can exert a force on the front baffle 22 during drilling, preventing deformation or deviation of the Teflon material during processing due to its own characteristics, which would affect the accuracy of the drilled through hole.

[0060] During the machining process, it is important to control the speed and feed rate of the electric drill. Excessive speed may cause the twist drill bit to overheat and wear, while insufficient speed will affect machining efficiency. Excessive feed rate may result in rough hole walls or even drill bit breakage, while insufficient feed rate will prolong machining time. Therefore, the optimal speed and feed rate need to be determined through multiple trials and adjustments based on the characteristics of the Teflon material, the specifications of the twist drill, and the machining requirements.

[0061] Preferably, the gap between the limiting blocks 14 is x, and the gap between the baffles 22 is y, with x being 0.07~0.1mm larger than y.

[0062] The gap between the limiting blocks 14 is 0.07~0.1mm larger than the gap between the baffles 22, so that a certain amount of assembly space can be reserved. During the drilling process, the two can fit tightly together, so that the limiting blocks 14 can limit the baffles 22 and prevent the baffles 22 from deforming during the processing, thereby affecting the accuracy of the through hole.

[0063] Preferably, the limiting block 14 is provided with a guide groove 11; two opposite guide grooves 11 on each set of clamping members form a guide hole.

Start the electric drill and let the twist drill bit gradually feed along the guide hole to ensure that the guide hole can play an effective guiding role throughout the entire processing. After drilling is completed, simply open the clamping component to separate the guide hole into the guide groove 11, reduce the resistance of the drill bit withdrawal, and improve the drilling efficiency.

[0067] The function of the limiting component is to fix the clamping component, prevent it from shifting during drilling, and ensure its position is stable. For specific structures, please refer to other existing structures, such as slots and buckle assemblies set on the worktable.

[0068] Preferably, the fastening member 10 is provided with a chip-receiving groove 12 corresponding to the guide hole; the chip-receiving groove 12 is located at the top of the limiting block 14 and communicates with the guide groove 11.

[0069] After machining to a certain depth, drill chips may not be easily removed in time. To ensure machining quality, a chip groove 12 is installed above the guide hole, allowing the drill chips to enter the chip groove 12 through the guide of the twist drill. This eliminates the need for repeated pulling and retraction, preventing the drill chips from affecting the drilling operation and improving drilling accuracy. After machining, the machined Teflon material is removed from the fixture, and the drill chips in the chip groove 12 are cleaned. Teflon material has good non-stick properties, making it easy to clean. Quality inspection is then performed. If the perpendicularity or dimensional accuracy of the hole does not meet the requirements, the cause needs to be analyzed, machining parameters adjusted, or the fixture design improved to avoid similar problems in subsequent machining.

This eliminates the need for repeated pulling and tucking, preventing the drill chips from affecting the drilling operation and improving drilling accuracy. After machining, the machined Teflon material is removed from the fixture, and the drill chips in the chip groove 12 are removed. Teflon material has good non-stick properties, making it easy to clean. Quality inspection is then performed. If the perpendicularity or dimensional accuracy of the hole does not meet the requirements, the cause needs to be analyzed, machining parameters adjusted, or the fixture design improved to avoid similar problems in subsequent machining.

[0089] Preferably, the guide hole has a chamfer of 13 on its side.

[0090] The 13-degree chamfer guides the twist drill bit into the pilot hole, ensuring that the twist drill bit can smoothly enter the pilot hole in sequence, thus improving drilling efficiency.

[0091] The specific implementation process of this embodiment is as follows: First, a matching fixture is designed and manufactured according to the size and shape of the PCB partition board 20 to be processed. The fixture is made of high-strength stainless steel to ensure its stability and durability during processing. The shape of the fixture matches the shape of the comb-shaped Teflon material, while maintaining a certain assembly gap of 0.07~0.1mm. On the fixture, a series of auxiliary pilot holes and pilot hole chamfers 13 are precisely machined at predetermined positions and angles. The diameter of these auxiliary pilot holes is slightly larger than the diameter of the twist drill used for processing to ensure that the twist drill can pass smoothly while providing sufficient guidance. Next, a suitable electric drill is selected, and a 300mm long twist drill made of ordinary carbon steel is clamped on the electric drill to reduce wear on auxiliary tools while enabling drilling operations. During processing, the fitted Teflon material and fixture are clamped in a vise to ensure their stable position. Then, start the electric drill and gradually feed the twist drill along the auxiliary pilot hole on the fixture, adding coolant during the process to cool it down before drilling into the Teflon material. During processing, it is crucial to control the drill's speed and feed rate. Excessive speed may cause the twist drill bit to overheat and wear, while insufficient speed will affect processing efficiency; excessive feed rate may result in rough hole walls or even drill bit breakage, while insufficient feed rate will prolong processing time. Therefore, the optimal speed and feed rate need to be determined through multiple trials and adjustments based on the characteristics of the Teflon material, the specifications of the twist drill, and the processing requirements. During drilling, the drill chips will be guided into the chip groove 12 for removal, eliminating the need for repeated pulling and tucking. After processing, remove the finished PCB separator board 20 from the fixture for cleaning and quality inspection. Remove the drill chips from the chip groove 12; the Teflon material has good non-stick properties, making cleaning relatively easy, and then proceed to the next operation.

[0092] Example 4

[0093] like Figures 1-3 As shown, this embodiment provides a PCB partition board drilling device, including a PCB partition board through-hole processing fixture as described in Embodiment 3.

[0094] Specifically, according to the predetermined drilling position and angle, a series of guide holes and chip grooves 12 are precisely machined on the fixture. By selecting a suitable electric drill and drill bit, the PCB partition plate 20 embedded in the fixture can be drilled. During the processing, the limiting block 14 reduces the deformation rate of the baffle 22. The setting of several guide holes and chip grooves 12 ensures the angle and smooth movement of deep hole processing, which can effectively process deep holes with a length of 260mm, and improve the drilling accuracy of the PCB partition plate 20 drilling device.

[0095] This fixture assists an electric drill in drilling holes in the PCB partition 20, producing high-precision through holes. Through the fixing of the fixing components and the guidance of the guide holes, the drill bit's position is ensured to be accurate, enabling effective machining of holes up to 260mm in length, thus improving the drilling accuracy of the drilling device. Furthermore, compared to gun drilling, this fixture is made of high-strength metal, reducing the cost of the PCB partition 20 drilling device and increasing its market competitiveness.
