Description

Technical Field

[0001] This invention relates to the field of computer motherboard manufacturing, and in particular to a drilling device and a manufacturing method for computer motherboards. Background Technology

[0002] As a core component of a computer system, the precision of the motherboard's manufacturing process directly affects the computer's operational stability. Drilling is an essential step in motherboard manufacturing, used to install and position the various electronic components on the motherboard and to establish circuit connections.

[0003] In existing technologies, drilling holes in computer motherboards mostly involves using a rotating drill bit to create the openings. However, this traditional drilling method has significant drawbacks: during processing, the high-speed friction between the drill bit and the motherboard material generates a large amount of debris, primarily consisting of motherboard substrate material and copper foil and other material debris adhering to the substrate surface. Because the drill bit is rotating at high speed, the centrifugal force it generates causes the debris to fly and disperse in all directions. This flying debris not only scatters into the gaps between various components of the processing equipment but may also adhere to the circuitry or solder joints of electronic components on the motherboard surface, greatly hindering subsequent debris collection and removal. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, the present invention provides a technical solution that can solve the above problems.

[0005] A drilling apparatus for a computer motherboard includes a frame, a positioning assembly, a drilling assembly, and a debris collection assembly.

The sealing cover is a cylindrical structure with an open bottom. The top of the sealing cover is connected to the lifting bracket via an elastic telescopic rod. A rubber sealing gasket is provided on the inner side of the lower end of the sealing cover.

[0008] The debris collection assembly includes a collection chamber, a negative pressure fan, and a filter. The collection chamber is fixed to the side of the frame, and the top of the collection chamber is connected to the side wall of the sealing cover through a telescopic suction pipe. The negative pressure fan is located on the top of the collection chamber, and the air inlet of the negative pressure fan is connected to the interior of the collection chamber. The filter is located inside the collection chamber, between the telescopic suction pipe and the negative pressure fan.

[0009] As a further aspect of the present invention: the positioning component includes a positioning stage, a plurality of positioning grippers and a vacuum suction cup. The positioning stage is fixed on the frame, the positioning grippers are symmetrically arranged on both sides of the positioning stage, the driving end of the positioning grippers faces the center of the positioning stage, and the vacuum suction cup is embedded in the upper surface of the positioning stage. The vacuum suction cup is connected to a vacuum pump through an air pipe.

[0010] As a further aspect of the present invention: the positioning gripper includes a gripper body and an electric push rod. The electric push rod is fixed to the side of the positioning platform, the gripper body is fixed to the output end of the electric push rod, and an anti-slip rubber pad is provided on the inner side of the gripper body.

[0011] As a further aspect of the present invention: the drilling assembly also includes a drive motor and a drill rod. The drive motor is fixed at the bottom of the lifting bracket, the output shaft of the drive motor is connected to the drill rod, the drill rod is set vertically downward, and the sealing cover is fitted on the outside of the drill rod.

[0012] As a further embodiment of the present invention: the lifting support includes a fixed rod, a lifting rod and a hydraulic cylinder. The fixed rod is vertically fixed on the frame, the lifting rod is sleeved inside the fixed rod, the cylinder body of the hydraulic cylinder is fixed to the top of the fixed rod, the piston rod of the hydraulic cylinder is connected to the top of the lifting rod, and the drive motor and the elastic telescopic rod of the sealing cover are both set at the bottom of the lifting rod.

[0013] As a further aspect of the present invention: a connecting bearing is provided on the top of the sealing cover, and the inner ring of the connecting bearing is slidably sleeved on the drill rod.

[0014] As a further aspect of the present invention: the filter element includes a primary filter and a high-efficiency filter, the primary filter is located near the air outlet of the telescopic suction tube, and the high-efficiency filter is located near the air inlet of the negative pressure fan, and the pore size of the primary filter is larger than that of the high-efficiency filter.

[0015] As a further aspect of the present invention: the bottom of the collection bin is provided with a slag discharge port, and a sealing cover is provided at the slag discharge port, and the sealing cover is connected to the collection bin by a thread.

[0016] As a further aspect of the present invention, it also includes a control system, which is electrically connected to the positioning component, the drilling component, and the debris collection component, respectively.

[0017] A method for machining a drilling device for a computer motherboard includes the following steps:

[0018] S1: Loading and positioning: Place the computer motherboard to be drilled on the upper surface of the positioning table. Start the positioning component through the control system. The gripper body clamps the motherboard to the side under the drive of the electric push rod. At the same time, the vacuum pump starts and the bottom of the motherboard is adsorbed and fixed by the vacuum suction cup.

[0019] S2: Sealing and fitting. The control system controls the lifting bracket to drive the drilling assembly to descend, so that the rubber sealing gasket at the lower end of the sealing cover fits tightly with the upper surface of the computer motherboard. The elastic telescopic rod contracts under pressure to ensure that a sealed space is formed between the sealing cover and the motherboard.

[0020] S3: Drilling and debris collection. The control system starts the drive motor to rotate the drill rod, while continuing to control the lifting bracket to descend, so that the drill rod feeds towards the surface of the main board to drill. During this process, the control system starts the negative pressure fan to create a negative pressure environment inside the sealing cover. The debris generated by drilling enters the collection chamber through the telescopic suction tube under the action of negative pressure. After being filtered by the filter, the debris remains in the collection chamber.

[0021] S4: Reset and unload. After drilling is completed, the control system controls the drive motor to stop running and controls the lifting bracket to drive the drill rod to rise. After the drill rod is completely withdrawn from the drill hole, the negative pressure fan is turned off. Then, the positioning jaws are released and the vacuum pump stops working to remove the processed motherboard.

[0022] S5: Debris cleaning. Regularly open the sealing cover at the bottom of the collection chamber to discharge the collected debris from the slag outlet, thus completing the centralized cleaning of debris.

[0023] As a further aspect of the present invention: in step S3, the feed speed of the drill rod is 0.5-1 mm / s, the rotation speed of the drive motor is 3000-5000 r / min, and the negative pressure value of the negative pressure fan is -0.05 to -0.08 MPa.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting a sealing cover to be fitted on the outside of the drill rod, during the drilling process, the sealing cover and the surface of the computer motherboard are closely fitted to form a sealed space, which can effectively prevent debris from flying in all directions. At the same time, in conjunction with the debris collection assembly composed of a negative pressure fan and a telescopic suction tube, a negative pressure is generated in the sealed space, which sucks the debris generated during drilling into the collection chamber in real time, realizing the sealed collection of debris, and fundamentally solving the problem of debris flying and difficult to collect and remove in existing drilling equipment.

[0034] Please see Figure 1-3 A drilling device for computer motherboards includes a frame 1, a positioning assembly 2, a drilling assembly 3, and a debris collection assembly 4.

[0035] Positioning component 2 is set on the workbench of rack 1 and is used to fix and position the computer motherboard.

[0036] The drilling assembly 3 is positioned above the positioning assembly 2 and connected to the frame 1 via a lifting bracket. A sealing cover 41 is fitted on the outer side of the drilling assembly 3. The sealing cover 41 is a cylindrical structure with an open bottom. The top of the sealing cover 41 is connected to the lifting bracket via an elastic telescopic rod. A rubber sealing gasket 42 is provided on the inner side of the lower end of the sealing cover 41.

[0037] The debris collection assembly 4 includes a collection chamber 43, a negative pressure fan 44, and a filter. The collection chamber 43 is fixed to the side of the frame 1. The top of the collection chamber 43 is connected to the side wall of the sealing cover 41 through a telescopic suction pipe. The negative pressure fan 44 is located on the top of the collection chamber 43. The air inlet of the negative pressure fan 44 is connected to the inside of the collection chamber 43. The filter is located inside the collection chamber 43, between the telescopic suction pipe and the negative pressure fan 44.

[0038] During operation, the computer motherboard is placed on the workbench of the rack 1 and fixed in place by the positioning component 2. Then, the drilling component 3 is driven by the lifting bracket to drill holes in the computer motherboard. During the drilling process, the sealing cover 41 is tightly fitted with the surface of the computer motherboard to form a sealed space, which can effectively prevent debris from flying around. At the same time, the debris collection component consisting of the negative pressure fan 44 and the telescopic suction tube creates negative pressure in the sealed space, sucking the debris generated during drilling into the collection chamber 43 in real time, achieving sealed collection of debris. This fundamentally solves the problem of debris flying and difficult to collect and remove in existing drilling equipment. The sealing cover 41 is connected to the lifting bracket by an elastic telescopic rod. When the lifting bracket drives the drilling component 3 to descend, the elastic telescopic rod can provide a buffer force to ensure that the rubber sealing gasket 42 at the lower end of the sealing cover 41 is tightly fitted with the surface of the motherboard, improving the sealing effect and avoiding damage to the surface of the motherboard, thus ensuring the quality of motherboard processing.

[0039] A further embodiment: The positioning component 2 includes a positioning platform 21, several positioning grippers, and a vacuum suction cup 22. The positioning platform 21 is fixed on the frame 1. The positioning grippers are symmetrically arranged on both sides of the positioning platform 21, with the driving end of the positioning grippers facing the center of the positioning platform 21. The vacuum suction cup 22 is embedded in the upper surface of the positioning platform 21 and is connected to a vacuum pump through an air pipe. The positioning gripper includes a gripper body 23 and an electric push rod 24. The electric push rod 24 is fixed on the side of the positioning platform 21, and the gripper body 23 is fixed on the output end of the electric push rod 24. The inner side of the gripper body 23 is provided with an anti-slip rubber pad 25.

[0040] The positioning stage 21 provides a flat bearing surface for the computer motherboard, ensuring uniform force distribution during drilling. Symmetrically arranged positioning jaws provide rigid clamping from the sides, while vacuum suction cups 22 provide bottom suction fixation, forming a dual positioning structure of side clamping and bottom suction. This structure prevents motherboard displacement due to rotational or feed forces during drilling and adapts to the positioning needs of motherboards of different sizes. Simultaneously, vacuum suction reduces indentation damage to the motherboard surface. The electric push rod 24 enables linear drive of the jaw body 23, and the clamping stroke and clamping force can be precisely adjusted through the control system 11 to adapt to motherboards of different thicknesses and sizes, preventing excessive clamping force from damaging the motherboard or insufficient clamping force from causing displacement. The anti-slip rubber pad 25 on the inner side of the jaw body 23 increases friction with the side of the motherboard, further improving positioning stability. At the same time, the flexible contact of the rubber material protects the edge circuits or packaging structures on the side of the motherboard from damage, ensuring the integrity of the motherboard's appearance and performance. This structure enables secure positioning of the motherboard, preventing displacement during drilling, improving drilling accuracy, and is suitable for positioning computer motherboards of different sizes and specifications.

[0041] A further solution: The drilling assembly 3 also includes a drive motor 31 and a drill rod 32. The drive motor 31 is fixed to the bottom of the lifting bracket. The output shaft of the drive motor 31 is connected to the drill rod 32. The drill rod 32 is set vertically downward. The sealing cover 41 is sleeved on the outside of the drill rod 32.

[0042] The drive motor 31 provides stable rotational power to the drill rod 32, ensuring sufficient drilling cutting force and uniform rotation speed, and improving the smoothness of the drilled surface; the lifting bracket enables precise feed control of the drill rod 32, ensuring drilling depth accuracy.

[0043] A further embodiment: The lifting support includes a fixed rod 33, a lifting rod 34, and a hydraulic cylinder 35. The fixed rod 33 is vertically fixed on the frame 1. The lifting rod 34 is sleeved inside the fixed rod 33. The cylinder body of the hydraulic cylinder 35 is fixed to the top of the fixed rod 33. The piston rod of the hydraulic cylinder 35 is connected to the top of the lifting rod 34. The elastic telescopic rods of the drive motor 31 and the sealing cover 41 are both located at the bottom of the lifting rod 34.

[0044] The sleeve structure of the fixed rod 33 and the lifting rod 34 can ensure the straightness of the lifting process and avoid the lifting rod 34 from swinging and causing the drilling position to shift. The hydraulic cylinder 35, as the driving mechanism, has the advantages of large output force, stable feed speed and precise control. It can adjust the feed force and speed of the drill rod according to different main board materials, which can ensure drilling efficiency and prevent the main board from being damaged due to excessive feed force.

[0045] A further solution: A connecting bearing 49 is provided on the top of the sealing cover 41, and the inner ring of the connecting bearing 49 is slidably sleeved on the drill rod 32.

[0046] By connecting the bearing 49, the sealing cover 41 and the drill rod 32 form an axial guiding fit. This not only limits the radial wobble of the drill rod 32 when it rotates at high speed, preventing borehole diameter deviation or uneven hole wall caused by the wobbling of the drill rod 32, but also provides a stable guiding effect for the lifting and lowering feed of the drill rod 32, reducing friction and wear between the drill rod 32 and the inner wall of the sealing cover 41, extending the service life of the drill rod 32 and the sealing cover 41, but also ensures that the gap between the sealing cover 41 and the drill rod 32 is uniform, maintaining the negative pressure stability of the sealed space.

[0047] A further solution: The filter element includes a primary filter 45 and a high-efficiency filter 46. The primary filter 45 is located near the air outlet of the telescopic suction pipe, and the high-efficiency filter 46 is located near the air inlet of the negative pressure fan 44. The pore size of the primary filter 45 is larger than that of the high-efficiency filter 46.

[0048] The system employs a dual filtration structure, with a coarse filter followed by a fine filter. The primary filter 45 intercepts larger particles of debris, preventing them from directly impacting the high-efficiency filter 46 and causing blockage, thus extending the replacement cycle of the high-efficiency filter 46. The high-efficiency filter 46 then filters out fine dust particles, preventing them from entering the negative pressure fan 44 and causing impeller wear or being discharged with the exhaust air, thus polluting the environment. This dual filtration not only improves the filtration effect but also reduces the maintenance cost of the filter components.

[0049] A further solution: The bottom of the collection chamber 43 is provided with a slag discharge port 47, and a sealing cover plate 48 is provided at the slag discharge port 47. The sealing cover plate 48 is connected to the collection chamber 43 by threads.

[0050] The bottom slag discharge port 47 conforms to the principle of gravity settling, and the collected debris can be naturally deposited at the bottom of the collection chamber 43. The debris can be quickly discharged by opening the sealing cover 48, which is convenient and efficient. The threaded sealing cover 48 has reliable sealing performance, which can prevent negative pressure leakage in the collection chamber 43 from affecting the debris collection effect, and at the same time prevent debris from overflowing from the slag discharge port 47 during storage, ensuring the sealing and practicality of the collection chamber 43.

[0051] A further option includes a control system 11, which is electrically connected to the positioning component 2, the drilling component 3, and the debris collection component 4.

[0052] The control system 11 enables the coordinated and automated operation of all components, which can precisely control the clamping force of the positioning gripper, the adsorption pressure of the vacuum suction cup 22, the rotation speed and feed speed of the drill rod 32, and the start and stop timing of the negative pressure fan 44. This not only improves the efficiency of drilling, but also avoids errors caused by manual operation, ensures the connection accuracy of each process, reduces the labor intensity of operators, and improves the operational safety of the equipment.

[0053] A method for machining a drilling device for a computer motherboard includes the following steps:

[0054] S1: Loading and positioning: Place the computer motherboard to be drilled on the upper surface of the positioning table 21. Start the positioning component 2 through the control system 11. The gripper body 23 clamps the motherboard to the side under the drive of the electric push rod 24. At the same time, the vacuum pump starts and the bottom of the motherboard is adsorbed and fixed by the vacuum suction cup 22.

[0055] S2: Sealing and fitting, the control system 11 controls the lifting bracket to drive the drilling assembly 3 to descend, so that the rubber sealing gasket 42 at the lower end of the sealing cover 41 is tightly fitted with the upper surface of the computer motherboard, and the elastic telescopic rod contracts under pressure to ensure that a sealed space is formed between the sealing cover 41 and the motherboard.

[0056] S3: Drilling and debris collection. The control system 11 starts the drive motor 31 to drive the drill rod 32 to rotate, and at the same time continues to control the lifting bracket to descend, so that the drill rod 32 feeds towards the surface of the main board to drill. During this process, the control system 11 starts the negative pressure fan 44 to create a negative pressure environment inside the sealing cover 41. The debris generated by drilling enters the collection chamber 43 through the telescopic suction tube under the action of negative pressure. After being filtered by the filter element, the debris remains in the collection chamber 43.

[0057] S4: Reset and unload. After drilling is completed, the control system controls the drive motor to stop running and controls the lifting bracket to drive the drill rod to rise. After the drill rod is completely withdrawn from the drill hole, the negative pressure fan is turned off. Then, the positioning jaws are released and the vacuum pump stops working to remove the processed motherboard.

[0058] S5: Debris cleaning. Periodically open the sealing cover 48 at the bottom of the collection chamber 43 to discharge the collected debris from the slag discharge port 47, thus completing the centralized cleaning of debris.

[0059] A further scheme: In step S3, the feed speed of drill rod 32 is 0.5-1mm / s, the speed of drive motor 31 is 3000-5000r / min, and the negative pressure value of negative pressure fan 44 is -0.05 to -0.08MPa.

[0060] Adapted to the cutting characteristics of computer motherboard substrates and surface copper foil, low-speed feed avoids motherboard substrate breakage or copper foil peeling due to excessive cutting force, while high-speed feed ensures processing efficiency, achieving a balance between accuracy and efficiency within this range; high-speed rotation allows the cutting edge of drill rod 32 to quickly cut the material, reducing friction time with the motherboard and lowering the probability of debris adhering to drill rod 32, while ensuring smooth hole walls and meeting hole diameter accuracy, avoiding rough hole walls caused by excessively low rotation speed; the negative pressure value is sufficient to adsorb debris in the sealed space in real time, preventing debris from flying due to centrifugal force; the negative pressure is not excessively increased, which can prevent the motherboard from deforming due to negative pressure, while reducing fan energy consumption and noise.

[0061] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this invention does not involve any improvement to the software and methods.

[0062] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
