Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing technology, specifically to a drill bit residual wire removal device. Background Technology

[0002] Printed circuit boards (PCBs) are important electronic components, serving as the support for electronic components and the carrier for their electrical connections. Because they are manufactured using electronic printing techniques, they are called "printed" circuit boards. During the processing of PCBs, it is necessary to remove oil stains, impurities, and residual wires from the drill bits from the board surface. Currently, only ultrasonic cleaning is used for this process.

[0003] Currently, after drilling printed circuit boards, metal wires (aluminum and copper wires) and circuit board debris remain on the drill bits. The industry practice is to use ultrasonic cleaning, but ultrasonic cleaning can only remove circuit board debris and cannot effectively remove metal wires. Therefore, manual removal of wires is also required. A worker may need to spend several hours cleaning a batch of drill bits, resulting in low overall efficiency. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a drill bit residual wire removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a drill bit residual wire removal device, comprising: The base plate has a first limiting plate and a second limiting plate spaced apart along a first direction on its top, and a third limiting plate and a fourth limiting plate spaced apart along a second direction. The first limiting plate, the second limiting plate, the third limiting plate and the fourth limiting plate cooperate to form a working area. The working area is used to place multiple needle storage boxes in sequence along the first direction. The top of the needle storage box carries multiple drill bits.

[0006] A cleaning mechanism is installed on both sides of the working area along the second direction, including a brush assembly and a displacement assembly. The brush assembly is arranged corresponding to the working area along the third direction, and the displacement assembly is driven to drive the brush assembly to move relative to the base plate along the first direction, so that the brush assembly contacts the plurality of drill bits and removes residual wire.

[0007] The drill bit residue removal device provided by this utility model, by setting up a cleaning mechanism including a brush assembly and a displacement mechanism, drives the brush assembly to move along a first direction, and can sequentially clean multiple drill bits placed in the drill bit storage box. This automated operation greatly improves cleaning efficiency, reduces the time and labor intensity of manual operation, and enables rapid removal of residual wires.

[0008] In some embodiments, the displacement assembly includes a first bearing seat, a first connecting rod, and a first slider. The first bearing seat is disposed on the side of the third limiting plate away from the fourth limiting plate along the second direction, and is correspondingly disposed on the top of the first limiting plate and the second limiting plate along the first direction. The first connecting rod extends along the first direction, with both ends connected to the first bearing seat. The first slider is slidably sleeved on the first connecting rod.

[0009] The displacement assembly further includes a second bearing seat, a second connecting rod, and a second slider. The second bearing seat is disposed on the side of the fourth limiting plate away from the third limiting plate along the second direction, and is correspondingly disposed on the top of the first limiting plate and the second limiting plate along the first direction. The second connecting rod extends along the first direction, with both ends connected to the second bearing seat. The second slider is slidably sleeved on the second connecting rod.

[0010] By adopting the above technical solution, the design of the dual-sided displacement mechanism makes the entire cleaning mechanism more stable during movement. By setting displacement mechanisms on both sides of the working area (the third and fourth limiting plates), this dual-sided design can provide more balanced motion control. During the cleaning process, the force on the brush assembly can be more evenly distributed on both sides, reducing vibration or displacement caused by uneven force on one side.

[0011] In some embodiments, the shifting assembly further includes a connecting plate and an adapter block. The connecting plate extends along the second direction and its bottom is connected to the first slider and the second slider, respectively. The adapter block is disposed on the top of the connecting plate and is correspondingly arranged along the third direction to the working area. The adapter block includes a fixed end and a connecting end. The fixed end is disposed near the end of the connecting plate along the first direction, and the connecting end extends along the third direction and is disposed on top of the fixed end. The connecting end has mounting through holes spaced apart along the second direction, and the brush assembly is disposed on one side of the connecting end along the first direction.

[0012] Using the above technical solution, the connecting plate connects the first and second sliders together, forming an integral structure that enhances the rigidity of the entire displacement mechanism. The adapter block design allows for three-dimensional adjustment of the brush assembly, enabling the device to better adapt to drill bits of different sizes and shapes. This multi-directional adjustment capability improves the flexibility and adaptability of the device.

[0013] In some embodiments, along the third direction, both the first bearing housing and the second bearing housing are positioned higher than the connecting plate.

[0014] By adopting the above technical solution, the height of the bearing housing can be adjusted to flexibly accommodate drill bits of different sizes and shapes. At the same time, the fact that both the first and second bearing housings are set higher than the connecting plate can limit the movement of the connecting plate.

[0015] In some embodiments, the brush assembly is a brush bar or a brush with a handle, and is made of soft steel.

[0016] Using the above technical solution, the soft steel brush material has a certain degree of flexibility, which can better adapt to the shape and contour of the drill bit surface. This flexibility allows the brush assembly to fit more closely to the drill bit surface during cleaning, thereby removing residual filaments more effectively.

[0017] In some embodiments, the first limiting plate, the second limiting plate, the third limiting plate, the fourth limiting plate, the first bearing seat, and the second bearing seat are all provided with bolt connection holes.

[0018] Using the above technical solution, the bolt connection makes the assembly and disassembly of the device very convenient. Through the bolt connection holes, the position and angle of each component can be flexibly adjusted to adapt to different working environments and cleaning needs.

[0019] In some embodiments, the drill bit residue removal device further includes a motor drive assembly located on the side of the first connecting rod away from the third limiting plate along the second direction. The motor drive assembly includes a linear module and a drive motor. The linear module extends along the first direction, and its sliding drive end is connected to the connecting plate. The drive motor is located at one end of the linear module along the first direction and is used to drive the sliding drive end to move the connecting plate relative to the base plate along the first direction.

[0020] Using the above technical solution, the combination of linear module and drive motor can achieve very precise motion control, and the motor drive component makes the entire cleaning process fully automated. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] refer to Figure 1 , Figure 1 A perspective view of a drill bit wire removal device 1 provided in an embodiment of the present invention is shown, wherein the brush assembly 30 is a brush with a handle; Figure 2 The diagram shows a schematic of the structure of the brush assembly 30 in a drill bit residual wire removal device 1 provided in an embodiment of the present invention, wherein the brush assembly 30 is a brush strip.

[0024] like Figure 1 and Figure 2 As shown, the technical solution provided in this application is a drill bit residue removal device 1, including a base plate 2 and a cleaning mechanism, wherein the top of the base plate 2 is along a first direction ( Figure 1 As shown in the X direction, a first limiting plate 20 and a second limiting plate are provided at intervals along the second direction (as indicated by the X direction). Figure 1 (As shown in the Y direction) A third limiting plate 21 and a fourth limiting plate 22 are provided at intervals. The first limiting plate 20, the second limiting plate, the third limiting plate 21 and the fourth limiting plate 22 cooperate to form a working area 23. The working area 23 is used to place multiple needle storage boxes in sequence along the first direction. The top of the needle storage box carries multiple drill bits.

[0025] The cleaning mechanism is installed on both sides of the work area 23 along the second direction, including a brush assembly 30 and a shifting assembly 31, with the brush assembly 30 along the third direction ( Figure 1 The shifting component 31 is connected to the brush component 30 via a transmission connection, and is used to drive the brush component 30 to move relative to the base plate 2 along the first direction so that the brush component 30 contacts multiple drill bits and removes residual wires. (As shown in the Z direction)

[0026] The drill bit residue removal device 1 provided in this application, by setting up a cleaning mechanism including a brush assembly 30 and a shifting mechanism, drives the brush assembly 30 to move along a first direction, thereby sequentially cleaning multiple drill bits placed in a drill bit storage box. This automated operation greatly improves cleaning efficiency, reduces the time and labor intensity of manual operation, and enables rapid removal of drill bit residue. Compared with the existing technology of manually cleaning drill bit residue, where a worker may need to spend several hours cleaning a batch of drill bits, this device can complete the cleaning of the same number of drill bits in a few minutes, and the cleaning quality is more consistent.

[0027] In some embodiments, reference Figure 1 The shifting assembly 31 includes a first bearing seat 310, a first connecting rod 311, and a first slider 312. The first bearing seat 310 is located on the side of the third limiting plate 21 away from the fourth limiting plate 22 along the second direction, and is correspondingly located on the top of the first limiting plate 20 and the second limiting plate along the first direction. The first connecting rod 311 extends along the first direction, and both ends are connected to the first bearing seat 310. The first slider 312 is slidably sleeved on the first connecting rod 311.

[0028] The shifting assembly 31 also includes a second bearing seat 313, a second connecting rod 314, and a second slider 315. The second bearing seat 313 is located on the side of the fourth limiting plate 22 away from the third limiting plate 21 along the second direction, and is correspondingly located on the top of the first limiting plate 20 and the second limiting plate along the first direction. The second connecting rod 314 extends along the first direction, with both ends connected to the second bearing seat 313. The second slider 315 is slidably sleeved on the second connecting rod 314.

[0029] For example, the design of the dual-sided displacement mechanism makes the entire cleaning mechanism more stable during movement. By setting displacement mechanisms on both sides of the working area 23 (the third limiting plate 21 and the fourth limiting plate 22), this dual-sided design can provide more balanced motion control. During the cleaning process, the force on the brush assembly 30 can be more evenly distributed on both sides, reducing vibration or displacement caused by uneven force on one side.

[0030] In some embodiments, reference Figure 1The shifting assembly 31 also includes a connecting plate 316 and an adapter block 317. The connecting plate 316 extends along a second direction and its bottom is connected to the first slider 312 and the second slider 315, respectively. The adapter block 317 is located on the top of the connecting plate 316 and is positioned in a third direction corresponding to the working area 23. The adapter block 317 includes a fixed end 318 and a connecting end 319. The fixed end 318 is located near the end of the connecting plate 316 along a first direction, and the connecting end 319 extends along a third direction and is located on top of the fixed end 318. The connecting end 319 has mounting through holes spaced apart along the second direction, and the brush assembly 30 is located on one side of the connecting end 319 along the first direction.

[0031] For example, the connecting plate 316 connects the first slider 312 and the second slider 315 together, forming an integral structure that enhances the rigidity of the entire shifting mechanism. The design of the adapter block 317 allows the brush assembly 30 to be adjusted in a third direction, enabling the device to better accommodate drill bits of different sizes and shapes. This multi-directional adjustment capability improves the flexibility and adaptability of the device. The connecting end 319 is provided with mounting through holes spaced apart along a second direction, a design that makes the installation of the brush assembly 30 very convenient. The mounting through holes can be flexibly adjusted according to the specific size and position of the brush assembly 30, ensuring that the brush assembly 30 can be accurately installed in the required position and can make more comprehensive contact with each drill bit. This design ensures that every part of the drill bit is cleaned, thereby improving the thoroughness of cleaning.

[0032] In some embodiments, reference Figure 1 Along the third direction, both the first bearing housing 310 and the second bearing housing 313 are positioned higher than the connecting plate 316.

[0033] For example, by adjusting the height of the bearing housing, drill bits of different sizes and shapes can be flexibly accommodated. At the same time, the first bearing housing 310 and the second bearing housing 313 are both set higher than the connecting plate 316 to limit the movement of the connecting plate 316.

[0034] In some embodiments, reference Figure 1 and Figure 2 The brush component 30 is a brush strip or a brush with a handle, made of soft steel.

[0035] For example, the soft steel brush material has a certain degree of flexibility, allowing it to better adapt to the shape and contour of the drill bit surface. This flexibility allows the brush assembly 30 to fit more closely to the drill bit surface during cleaning, thereby removing residual filaments more effectively. The stubble brush is suitable for shorter drill bit reservoirs, and residual filaments on the drill bit are removed by manually dragging the stubble brush. The brush bar, on the other hand, is suitable for longer drill bit reservoirs, where manual dragging is inconvenient; in this case, removal is achieved by a motor-driven assembly.

[0036] In some embodiments, reference Figure 1 The first limiting plate 20, the second limiting plate, the third limiting plate 21, the fourth limiting plate 22, the first bearing seat 310 and the second bearing seat 313 are all provided with bolt connection holes 320.

[0037] For example, the bolted connection makes the assembly and disassembly of the device very convenient. Through the bolt connection holes 320, the position and angle of each component can be flexibly adjusted to adapt to different working environments and cleaning needs. For instance, if it is necessary to adjust the size or shape of the working area 23, this can be achieved by adjusting the position of the limit plate.

[0038] In some embodiments, reference Figure 1 The drill bit residue removal device 1 also includes a motor drive assembly. The motor drive assembly is located on the side of the first connecting rod 311 away from the third limiting plate 21 along the second direction. It includes a linear module and a drive motor. The linear module extends along the first direction, and its sliding drive end is connected to the connecting plate 316. The drive motor is located at one end of the linear module along the first direction and is used to drive the sliding drive end to move the connecting plate 316 relative to the base plate 2 along the first direction.

[0039] For example, the combination of a linear module and a drive motor enables highly precise motion control, and the motor drive assembly automates the entire cleaning process. Operators only need to start the equipment to automatically remove drill bit residue, significantly reducing manual intervention and improving efficiency. The motor drive assembly is primarily used when the brush assembly 30 consists of brush strips; in this case, manual dragging is not recommended, as the motor drive assembly drives the brush strips to clean the drill bit.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
