Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and more specifically, to a circuit board drilling device. Background Technology

[0002] Printed circuit boards (PCBs) are a crucial component in modern electronic products, making the drilling process particularly important. Drilling not only involves creating various types of holes on the PCB, such as through-holes and blind vias, but also ensuring the positional accuracy and wall quality of these holes to achieve precise mounting of electronic components and reliable circuit connections. Traditional PCB drilling equipment typically includes a motor-driven spindle equipped with a drill bit. Drilling is performed by adjusting the vertical position of the spindle and the horizontal position of the circuit board. To reduce vibration during spindle rotation, bearings are usually fitted around the spindle to improve drilling stability and accuracy.

[0003] However, during the operation of existing PCB drilling production equipment, the high-speed friction between the spindle and the bearing generates a large amount of heat. If heat is not dissipated in time, the bearing and the shaft will deform due to thermal expansion. This deformation will amplify the rotational eccentricity of the shaft, thereby affecting the drilling accuracy. Utility Model Content

[0004] This application provides a circuit board drilling device to solve the problem in the prior art that when drilling PCB boards, the spindle and bearing are deformed due to thermal expansion caused by high-speed friction, which in turn affects the drilling accuracy.

[0005] This application provides a circuit board drilling device, including:

[0006] A load-bearing structure is used to support the target component.

[0007] Supporting structure, installed on the load-bearing structure;

[0008] A drilling structure, at least partially rotatably mounted on a support structure, includes a drill bit for drilling a hole in a target component. The drilling structure also includes a rotating component and a vibration damping component, with the vibration damping component sleeved on the rotating component and the drill bit mounted on the rotating component so that the vibration damping component remains stationary relative to the rotating component when the rotating component drives the drill bit to rotate.

[0009] A cooling structure is installed on the load-bearing structure. The cooling structure includes a cooling component installed on the vibration damping component, so as to cool the vibration damping component during the drilling process of the drilling structure to drill the target component.

[0010] Furthermore, the drilling structure also includes a hydraulic component, a drive component, and a mounting component. The hydraulic component is mounted on the support structure, and the telescopic end of the hydraulic component is equipped with a drive component. The drive end of the drive component is equipped with a mounting component, wherein the drill bit is mounted on the mounting component.

[0011] Furthermore, the cooling structure also includes a cooling tank and a cooling pipe assembly. The cooling tank is mounted on the supporting structure, one end of the cooling pipe assembly is connected to the cooling tank, and the other end of the cooling pipe assembly is connected to the cooling component, so as to deliver coolant to the cooling component through the cooling pipe assembly to cool the vibration damping component.

[0012] Furthermore, the cooling assembly includes: a delivery pipe, the inlet end of which is connected to the cooling box, and the outlet end of which is connected to the cooling components;

[0013] The output pipe has an inlet end that connects to the cooling components and an outlet end that connects to the cooling box.

[0014] The pump body is installed on the output pipe to deliver the coolant in the cooling components to the cooling tank.

[0015] Furthermore, the cooling assembly also includes a liquid delivery component and a liquid delivery pipe. The liquid delivery component is connected to the outlet end of the delivery pipe and the inlet end of the output pipe, respectively. The inlet end of the liquid delivery pipe is connected to the liquid delivery component, and the outlet end of the liquid delivery pipe is connected to the cooling component.

[0016] Furthermore, the supporting structure includes: a supporting base plate; and a movable base plate movably disposed on the supporting base plate, the movable base plate being used to support the target component so as to transport the target component to the target location via the movable base plate.

[0017] Furthermore, the supporting structure also includes a clamping assembly, which is movably mounted on the movable base plate to clamp the target component when the target component is in the target position.

[0018] Furthermore, the clamping assembly includes: a telescopic component, the fixed end of which is disposed on the movable base plate;

[0019] A clamping member is disposed at the telescopic end of the telescopic component. The clamping member includes a first clamping part and a second clamping part. The extension directions of the first clamping part and the second clamping part are perpendicular. The first clamping part and the second clamping part together form a clamping surface for contacting the target component, so as to clamp the target component through the clamping surface when the target component is in the target position.

[0020] Furthermore, the clamping assembly also includes a guide component disposed on the clamping member, and the bearing structure also includes a guide position disposed on the bearing base plate, the guide component and the guide position cooperating to guide the clamping member by the guide position and the guide component when the clamping member moves toward the target member; and / or, the clamping assembly also includes a protective component disposed on the clamping surface.

[0021] Furthermore, the circuit board drilling device also includes a heat dissipation assembly, which includes a heat dissipation shell, a heat dissipation component, and an anti-collision component. The heat dissipation shell is mounted on the load-bearing structure and has a heat dissipation position inside. The anti-collision component is mounted on the heat dissipation shell, and the anti-collision component and the heat dissipation position together form an installation space. The heat dissipation component is rotatably mounted in the installation space. The heat dissipation assembly corresponds to the vibration damping component so that the vibration damping component is cooled by the heat dissipation assembly.

[0022] This application, by mounting a vibration damping component on a rotating component, and enabling it to remain relatively stationary while the rotating component drives the drill bit to rotate, greatly reduces the vibration generated by the rotating component during high-speed rotation, avoids drilling position deviation caused by this, and significantly improves drilling accuracy and circuit board quality.

[0023] The cooling structure, especially the cooling components on the vibration damping parts, can continuously cool the vibration damping parts during the drilling process, preventing the components from thermally expanding and deforming due to the heat generated by high-speed friction. This avoids amplifying the rotational eccentricity error of the rotating parts and further improves the stability and accuracy of drilling.

[0024] Effective cooling of the vibration damping components by the cooling system not only reduces thermal stress damage to other components but also indirectly extends the overall service life of the drilling structure and lowers equipment maintenance costs. Simultaneously, the efficient operation of the vibration damping components reduces wear on rotating parts and the drill bit, making the entire circuit board drilling device more durable.

[0025] In summary, the circuit board drilling device provided in this application effectively solves the problem of drilling accuracy being affected by thermal expansion and vibration in the prior art through the design of the drilling structure and cooling structure, achieving higher drilling accuracy, longer equipment service life, and better production efficiency.

[0037] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Printed circuit boards (PCBs) are a crucial component in modern electronic products, making the drilling process particularly important. Drilling not only involves creating various types of holes on the PCB, such as through-holes and blind vias, but also ensuring the positional accuracy and wall quality of these holes to achieve precise mounting of electronic components and reliable circuit connections. Traditional PCB drilling equipment typically includes a motor-driven spindle equipped with a drill bit. Drilling is performed by adjusting the vertical position of the spindle and the horizontal position of the circuit board. To reduce vibration during spindle rotation, bearings are usually fitted around the spindle to improve drilling stability and accuracy.

[0039] However, during the operation of existing PCB drilling production equipment, the high-speed friction between the spindle and the bearing generates a large amount of heat. If heat is not dissipated in time, the bearing and the shaft will deform due to thermal expansion. This deformation will amplify the rotational eccentricity of the shaft, thereby affecting the drilling accuracy.

[0040] Therefore, this application provides a circuit board drilling device to solve the problem in the prior art that when drilling PCB boards, the spindle and bearing are deformed due to thermal expansion caused by high-speed friction, which in turn affects the drilling accuracy.

[0041] like Figures 1 to 6 As shown, the circuit board drilling apparatus provided in this application embodiment includes:

[0042] A load-bearing structure is used to support the target component.

[0043] Supporting structure, installed on the load-bearing structure;

[0044] The drilling structure 3 is at least partially rotatably mounted on the support structure. The drilling structure 3 includes a drill bit 36 ​​for drilling holes in the target component. The drilling structure 3 also includes a rotating component 33 and a vibration damping component 34. The vibration damping component 34 is sleeved on the rotating component 33. The drill bit 36 ​​is mounted on the rotating component 33 so that when the rotating component 33 drives the drill bit 36 ​​to rotate, the vibration damping component 34 remains stationary relative to the rotating component 33.

[0045] A cooling structure is provided on the load-bearing structure. The cooling structure includes a cooling component 37 provided on the vibration damping component 34, so as to cool the vibration damping component 34 through the cooling component 37 during the drilling process of the drilling structure 3 to drill the target component.

[0046] Since the vibration damping component 34 in the drilling structure 3 of this technical solution is sleeved on the rotating component 33 and can remain relatively stationary when the rotating component 33 drives the drill bit 36 ​​to rotate, this greatly reduces the vibration generated by the rotating component 33 when rotating at high speed, avoids the drilling position deviation caused by it, and significantly improves the drilling accuracy and the quality of the circuit board.

[0047] The cooling structure, especially the cooling component 37 on the vibration damping component 34, can continuously cool the vibration damping component 34 during the drilling process, preventing the component from thermally expanding and deforming due to the heat generated by high-speed friction, thereby avoiding the amplification of the rotational eccentricity error of the rotating component 33 and further improving the stability and accuracy of drilling.

[0048] The effective cooling of the vibration damping component 34 by the cooling component 37 not only reduces the damage of thermal stress to other components, but also indirectly extends the overall service life of the drilling structure 3 and reduces equipment maintenance costs. At the same time, the efficient operation of the vibration damping component 34 reduces the wear of the rotating component 33 and the drill bit 36, making the entire circuit board drilling device more durable.

[0049] In summary, the circuit board drilling device provided in this application effectively solves the problem of the drill bit 36's accuracy being affected by thermal expansion and vibration in the prior art through the design of the drilling structure 3 and the cooling structure, achieving higher drilling accuracy, longer equipment service life, and better production efficiency.

[0050] Furthermore, the drilling structure 3 also includes a hydraulic component 31, a driving component 32, and a mounting component 35. The hydraulic component 31 is mounted on the support structure, the extension end of the hydraulic component 31 is provided with the driving component 32, and the driving end of the driving component 32 is provided with the mounting component 35. The drill bit 36 ​​is mounted on the mounting component 35.

[0051] Optionally, the hydraulic component 31 is a hydraulic rod, the drive component 32 is a drive motor, and the mounting component 35 is a mounting base. The mounting component 35 is fixedly connected to the end of the drive motor, thereby driving the drill bit 36 ​​to rotate through the mounting component 35.

[0052] As a hydraulic component 31, the hydraulic rod's precise extension and retraction control enables fine-tuning of the drive component 32 (drive motor) and its mounting component 35 (mounting seat) in the vertical direction. This provides a more stable and precise feed path for the drill bit 36, ensuring the consistency of drilling depth and diameter, and improving the verticality and coaxiality of the drilling.

[0053] The drive motor, as the driving component 32, provides sufficient power to the mounting base, ensuring high-speed rotation and stable output of the drill bit 36 ​​during drilling. Simultaneously, the combination of the hydraulic rod and the drive motor allows the equipment to quickly respond to and adjust drilling force and speed when dealing with circuit boards of different thicknesses or materials, adapting to diverse drilling needs.

[0054] The mounting base, serving as the carrier of drill bit 36, is fixedly connected to the end of the drive motor. This design not only ensures the stability and accuracy of drill bit 36 ​​during operation but also facilitates its quick replacement and maintenance. During mass production, different drill bit specifications can be flexibly changed according to different circuit board designs and hole diameter requirements, improving production efficiency and flexibility.

[0055] The synergistic effect of the hydraulic rod, drive motor, and mounting base not only optimizes the internal layout of the drilling structure 3 but also enhances the connection stability and overall reliability between components. In continuous operation, this coordination ensures the continuous operation of the circuit board drilling device, reducing downtime and thus lowering production costs.

[0056] Furthermore, the cooling structure also includes a cooling box 3111 and a cooling pipe assembly. The cooling box 3111 is mounted on the support structure. One end of the cooling pipe assembly is connected to the cooling box 3111, and the other end of the cooling pipe assembly is connected to the cooling component 37, so as to deliver coolant to the cooling component 37 through the cooling pipe assembly to cool the vibration damping component 34.

[0057] Furthermore, the cooling pipe assembly includes:

[0058] The conveying pipe has its inlet end connected to the cooling box 3111 and its outlet end connected to the cooling component 37.

[0059] The output pipe has an inlet end that connects to the cooling component 37 and an outlet end that connects to the cooling box 3111.

[0060] Pump body 3112 is installed on the output pipe to deliver coolant in the cooling component 37 to the cooling tank 3111.

[0061] Furthermore, the cooling assembly also includes a liquid delivery component 310 and a liquid delivery pipe 39. The liquid delivery component 310 is connected to the outlet end of the delivery pipe and the inlet end of the output pipe, respectively. The inlet end of the liquid delivery pipe 39 is connected to the liquid delivery component 310, and the outlet end of the liquid delivery pipe 39 is connected to the cooling component 37.

[0062] Specifically, such as Figure 2 As shown, the cooling assembly also includes a support 38. One end of the support 38 is connected to the liquid delivery component 310, and the other end of the support 38 is connected to the cooling component 37. It is used to support the liquid delivery pipe 39 disposed between the liquid delivery component 310 and the cooling component 37. There are multiple liquid delivery pipes 39 and multiple supports 38. The multiple supports 38 and multiple liquid delivery pipes 39 are arranged at intervals.

[0063] The cooling tank 3111 serves as a storage and replenishment source for the coolant, and together with the delivery and output pipes, it constitutes the coolant circulation system. Through the positive pressure and return force of the pump body 3112, the coolant is ensured to be evenly distributed and circulated efficiently inside and outside the cooling component 37, significantly enhancing the cooling effect on the vibration damping component 34, effectively suppressing the heat accumulation generated by high-speed rotation, and avoiding the impact of thermal expansion and contraction on accuracy.

[0064] The design of the delivery and output pipelines, combined with the pump body 3112, enables precise regulation of the coolant temperature. By adjusting the valve opening size of the pump body 3112, the flow rate and circulation speed of the coolant can be adjusted, maintaining the optimal temperature range of the coolant within the cooling component 37. This ensures that the bearing, i.e., the vibration damping component 34, operates at its optimal operating temperature, thereby improving the stability of the device and the drilling accuracy.

[0065] The combined use of the liquid delivery pipe 39 and the liquid delivery component 310 not only simplifies the coolant delivery path, but also increases the reliability of coolant delivery through the spaced arrangement of multiple liquid delivery pipes 39 and brackets 38. Even if individual liquid delivery pipes 39 become blocked or leak, the remaining liquid delivery pipes 39 can still work normally, ensuring the continuous operation of the cooling system.

[0066] The bracket 38 not only supports the liquid delivery pipe 39, but also optimizes the spatial layout of the cooling pipe assembly, so that the cooling structure and the drilling structure 3 are closely integrated without occupying extra space, thus promoting the overall compactness and ease of operation of the equipment.

[0067] Furthermore, the load-bearing structure includes: a load-bearing base plate 1;

[0068] The movable base plate 45 is movably mounted on the support base plate 1. The movable base plate 45 is used to carry the target component so that the target component can be transported to the target position via the movable base plate 45.

[0069] like Figure 1 and Figure 4 As shown, a conveying component 4 is provided on the supporting base plate 1. The conveying component 4 includes multiple first slide rails 41, which are arranged on the supporting base plate 1 and spaced apart sequentially. The multiple first slide rails 41 extend along a first direction. A first slider 42 is provided on each first slide rail 41, and each first slider 42 is slidably connected to its corresponding first slide rail 41. At least one first slider 42 is provided on each first slider 42. The conveying component 4 also includes multiple second slide rails 43, each second slide rail 43 is provided with a second slider 44, and each second slider 44 is slidably connected to its corresponding second slide rail 43. A movable base plate 45 is provided on the second sliders 44, thereby realizing the function of the conveying component 4 to transport the movable base plate 45 and the target component located on the movable base plate 45 to the target position.

[0070] A two-dimensional positioning platform is formed by providing multiple first slide rails 41 and second slide rails 43 extending along a first direction on the supporting base plate 1, and first sliders 42 and second sliders 44 slidably connected thereon. This structure allows the moving base plate 45 to move smoothly and precisely in the X and Y axis directions, ensuring that the target part can be accurately moved to the predetermined drilling position, greatly improving drilling accuracy.

[0071] Each first slide rail 41 and each second slide rail 43 is arranged sequentially at intervals and forms a stable sliding connection with the corresponding slider. This effectively distributes the load during movement, reduces local wear, and enhances the stability and durability of the movement of the moving base plate 45.

[0072] Because the slide rail and slider design of the transport component 4 can be flexibly adjusted, it can adapt to circuit boards of different sizes and shapes, increasing the versatility and flexibility of the device. This allows the same circuit board drilling device to be used to produce PCB products of various specifications, reducing production line changeover time and costs.

[0073] Furthermore, the support structure also includes a clamping assembly 46, which is movably disposed on the movable base plate 45 to clamp the target component when the target component is in the target position.

[0074] The combined use of clamping component 46 and movable base plate 45 can firmly clamp the circuit board after it has been accurately transported to the target position, ensuring that it remains stationary during the drilling operation. This avoids positioning offset caused by slight movement or vibration of the circuit board and effectively improves the accuracy of drilling.

[0075] The automatic clamping function of clamping component 46 reduces the time required for manual positioning and fixing of circuit boards, simplifies the operation process, and improves the automation of circuit board loading, positioning and drilling, thereby significantly improving production efficiency.

[0076] The clamping assembly 46, which is movably mounted on the movable base plate 45, is designed to adjust its position and control its clamping force according to the different sizes and shapes of the circuit boards, thereby enhancing the equipment's adaptability to different circuit boards and its processing flexibility, and meeting diverse production needs.

[0077] Furthermore, the clamping assembly 46 includes:

[0078] Telescopic component 461, the fixed end of telescopic component 461 is set on the movable base plate 45;

[0079] Clamping member 462 is disposed at the telescopic end of telescopic member 461. Clamping member 462 includes a first clamping part and a second clamping part. The extension directions of the first clamping part and the second clamping part are perpendicular. The first clamping part and the second clamping part together form a clamping surface for contacting the target component, so as to clamp the target component through the clamping surface when the target component is in the target position.

[0080] Optionally, the telescopic component 461 is a telescopic rod.

[0081] The vertical extension design of the first and second clamping parts forms a three-dimensional clamping surface, which ensures that the circuit board is firmly fixed in the X, Y and Z directions, ensuring the absolute positioning of the circuit board during the drilling process, avoiding any slight movement in any direction, and greatly improving drilling accuracy.

[0082] The use of telescopic component 461 (telescopic rod) enables clamping component 462 to automatically adjust the distance to the circuit board within a certain range. This adaptability can adapt to circuit boards of different thicknesses and sizes, ensuring that the best fit is achieved every time the clamping is performed, and reducing positioning deviations caused by size differences.

[0083] The clamping surface formed by the first clamping part and the second clamping part can evenly distribute the clamping force, avoiding pressure concentration and damage to the circuit board caused by applying force in one direction, protecting the integrity of the circuit board and reducing the production scrap rate.

[0084] The automatic telescopic feature of the telescopic component 461 simplifies the operator's circuit board loading and unloading steps. Simply place the circuit board on the movable base plate 45, and the telescopic component 461 will automatically adjust to the appropriate position and fix it in place by the clamp 462. No additional manual adjustment is required, which greatly improves the convenience and efficiency of operation.

[0085] Furthermore, the clamping assembly 46 also includes a guide member 481, which is disposed on the clamping member 462. The bearing structure also includes a guide position 482 disposed on the bearing base plate 1. The guide member 481 and the guide position 482 cooperate to guide the clamping member 462 as it moves toward the target member. The guide position 482 and the guide member 481 guide the clamping member 462. And / or, the clamping assembly 46 also includes a protective member 463 disposed on the clamping surface.

[0086] Optionally, the guide component 481 is a guide block disposed on the clamping assembly 46.

[0087] Optionally, the guide position 482 is a guide groove provided on the bearing base plate 1, and the guide block and the guide slider are slidably connected.

[0088] Optionally, the protective component 463 may be made of a flexible material such as a rubber pad.

[0089] The guiding engagement between the guide component 481 and the guide position 482 on the supporting base plate 1, such as the sliding connection between the guide block and the guide groove, provides path guidance for the movement of the clamping component 462 toward the circuit board, ensuring the linearity of the clamping action and the accuracy of the positioning, avoiding possible deviations during the clamping process, and improving the accuracy and reliability of drilling.

[0090] The combined use of guide component 481 and guide position 482 not only optimizes the movement path of clamping assembly 46, but also improves the movement speed and response efficiency of clamping component 462 by restricting the movement direction, thereby reducing positioning time.

[0091] The addition of protective components 463 (such as rubber pads) provides flexible cushioning for the area where the clamping surface contacts the circuit board, avoiding scratches or indentations that may be caused by direct contact of hard materials with the circuit board surface, protecting the appearance quality and internal structure of the circuit board, and reducing the scrap rate in the production process.

[0092] The flexible material properties of the protective component 463 enable it to adapt to the slight unevenness of the circuit board surface, ensuring that the clamping surface and the circuit board surface achieve the best fit, further improving the positioning accuracy and the stability of the circuit board fixation.

[0093] The precise guidance of the guide component 481 and the buffering effect of the protective component 463 reduce potential damage to the circuit board during positioning and fixing, reduce the waste of raw materials caused by circuit board damage, and also reduce the frequency of equipment maintenance and replacement of clamping components, thereby reducing production costs.

[0094] Furthermore, the circuit board drilling device also includes a heat dissipation assembly 47, which includes a heat dissipation housing 471, a heat dissipation component 472, and an anti-collision component 473. The heat dissipation housing 471 is mounted on the load-bearing structure and has a heat dissipation position inside. The anti-collision component 473 is mounted on the heat dissipation housing 471, and the anti-collision component 473 and the heat dissipation position together form an installation space. The heat dissipation component 472 is rotatably mounted in the installation space. The heat dissipation assembly 47 corresponds to the vibration damping component 34 so as to dissipate heat from the vibration damping component 34 through the heat dissipation assembly 47.

[0095] Optionally, the heat dissipation component 472 is a fan, and the anti-collision component 473 is an anti-collision bracket.

[0096] The design of the heat dissipation component 47 corresponding to the vibration damping component 34, by forming a heat dissipation position inside the heat dissipation housing 471 and placing the heat dissipation component 472 (such as a fan) in the installation space adjacent to the vibration damping component 34, can directly and effectively dissipate heat from the vibration damping component 34. This design ensures that the vibration damping component 34, i.e., the bearing, can quickly release the accumulated heat after long-term high-speed rotation, maintain the temperature stability of the bearing, reduce deformation caused by thermal expansion and contraction, and thus improve the accuracy and stability of drilling.

[0097] The installation of anti-collision components 473 (such as anti-collision brackets) provides physical protection for heat dissipation components 472, avoiding the impact of external collisions on heat dissipation performance.

[0098] Based on the cooling component 37, the newly added heat dissipation component 47 provides a second layer of heat dissipation protection. Even if the cooling system fails, the heat dissipation component 47 can function independently, ensuring the safe operation of the equipment under abnormal conditions and reducing the safety risks caused by overheating.

[0099] Specifically, such as Figure 1 As shown, the support structure includes multiple support frames 2 mounted on the bearing base plate 1. Two support frames 2 are provided with a connecting rod at the ends away from the bearing base plate 1. In this embodiment, there are two connecting rods. A connecting plate is provided between the two connecting rods. The cooling box 3111 and the pump body 3112 in the cooling structure are both mounted on the connecting plate.

[0100] Multiple support frames 2 are evenly distributed on the bearing base plate 1, which effectively disperses the weight of the cooling box 3111 and the pump body 3112, ensuring the stability of the cooling components installation, reducing the displacement of the cooling system caused by equipment vibration or improper operation, and ensuring the normal operation of the coolant circulation system and the reliability of the cooling effect.

[0101] By setting up connecting rods and connecting plates, the cooling tank 3111 and the pump body 3112 are integrated on a single platform, which not only simplifies the layout of the cooling system, but also makes the supply and circulation path of the coolant more direct and efficient, reduces pipe resistance, accelerates the circulation speed of the coolant, and improves cooling efficiency.

[0102] The design of the support structure provides additional installation space for the cooling structure, avoids conflicts between the cooling components and the main operating area, optimizes the utilization of the internal space of the equipment, and makes the equipment structure more compact, facilitating operation and maintenance.
