Description

Technical Field

[0001] The present invention relates to the technical field of flexible circuit boards, and in particular to a PET substrate drilling device. Background Art

[0002] Flexible circuit boards (FPCs) are bendable printed circuit boards (PCBs) made from a flexible insulating substrate. They are manufactured using a PET substrate through processes such as circuit printing. Photolithography and etching processes create precise conductive patterns. These boards can be bent, folded, and rolled freely to accommodate three-dimensional layout requirements. Therefore, prior to subsequent manufacturing processes, positioning holes and other components must be pre-processed into the PET substrate according to processing requirements.

[0003] Traditional mechanical drilling has three major technical bottlenecks: (1) thermal deformation of the PET material leads to aperture deviation (more than ±50μm); (2) drill bit wear causes cumulative error; and (3) positioning inaccuracy of multi-layer stacked drilling. Therefore, it is impossible to effectively achieve efficient and high-precision drilling on PET substrates. Summary of the Invention

[0004] The invention discloses a PET substrate drilling device, which aims to solve the technical problem of being unable to effectively realize high-efficiency and high-precision drilling on a PET substrate.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A PET substrate drilling device includes a stand, and further includes: a drilling mechanism connected to the inner wall of the top end of the stand; an annular guide rail provided at the bottom end of the drilling mechanism, with a partition fixedly connected to the middle position of the annular guide rail; a clamping mechanism provided at the bottom end of the drilling mechanism and movably connected to the annular guide rail; a cleaning mechanism located between the plurality of clamping mechanisms; and a drying mechanism located on one side of the drilling mechanism. The drilling mechanism includes: two groups of multidimensional guide rails, which are fixedly connected in parallel to the inner wall of the top end of the stand; an ultraviolet laser instrument, which is movably connected to one of the multidimensional guide rails; a micro-drill drilling machine, which is movably connected to the other multidimensional guide rail; a vacuum insulation panel 1, which is fixedly connected to the inner wall of the top end of the stand and is located between the two groups of multidimensional guide rails; a vacuum insulation panel 2, whose two ends are respectively fixedly connected to two hinged rods, and the vacuum insulation panel 2 is hinged to the bottom end of the vacuum insulation panel 1 through the hinged rods, and the outer walls of the vacuum insulation panel 1 and the vacuum insulation panel 2 are respectively coated with thermal insulation coatings; a weight block, which is fixedly embedded in the inner wall of the bottom end of the vacuum insulation panel 2.

[0006] By setting up a drilling mechanism, multiple PET substrates are translated and passed through the UV laser and the micro drill drilling machine in sequence. The guide holes are first pre-opened by the UV laser to provide a physical guide channel for the mechanical drill bit of the micro drill drilling machine, thereby compressing the hole position deviation to the greatest extent. At the same time, based on the simultaneous operation of the UV laser and the micro drill drilling machine, the drilling accuracy and speed are optimized. At the same time, the laser pre-opening can reduce the drill cutting amount, thereby protecting and extending the life of the drill bit. In addition, based on the setting of the vacuum insulation panel one and the vacuum insulation panel two, and the coating of the thermal insulation coating, an effective heat radiation isolation effect can be achieved, which can directly block the conduction of heat radiation and shorten the setting distance between the UV laser and the micro drill drilling machine, thereby reducing the floor space of the device, reducing construction costs, and not hindering the translation of the PET substrate.

[0007] In a preferred embodiment, the clamping mechanism includes: two limit frames, fixedly connected to the outer wall of the partition, and the two limit frames are respectively located directly below the micro-drill drilling machine and the ultraviolet laser; two bases, respectively movably sleeved on the outside of the two limit frames, and springs are respectively fixedly connected between the limit frames and the bases; multiple through holes are respectively arranged on the top outer wall of each base, and correspond to the drilling positions of the substrate.

[0008] In a preferred embodiment, the clamping mechanism further comprises: a plurality of slides movably connected to the annular guide rail; a square through-groove extending through the center of the bottom end of the slide, with chamfers provided on both sides of the square through-groove, and the base passing through the square through-groove; and a C-shaped limit frame fixedly connected to the top outer wall of the slide and located on both sides of the square through-groove. The clamping mechanism further includes: a top frame, which is attached to the top outer wall of the slide, and a C-shaped limit frame movably attached to the outer periphery of the top frame; a handle, which is fixedly connected to the top outer wall of the top frame; a magnetic sheet 1, which is respectively fixedly attached to the bottom outer wall of the top frame and the top outer wall of the slide, and the top frame and the slide are magnetically attracted by the magnetic sheet 1, so that the bottom outer wall of the PET substrate is just flush with the bottom end of the magnetic sheet 1 at the bottom of the top frame; The cleaning mechanism includes: a liquid pipe, which is fixedly connected to the partition through multiple limit frames, and its input end passes through the partition and is fixedly connected to the water tank, and a water pump is fixedly installed at the connection between the liquid pipe and the water tank; a mounting frame, which is sleeved on the outside of the water tank and fixedly connected to the vertical frame; multiple nozzles, which are fixedly connected to multiple output ends of the liquid pipe, and the pressures of the multiple nozzles are set in increasing order; a liquid collecting tank, which is arranged at the bottom ends of the multiple nozzles.

[0009] A cleaning mechanism is provided. In the cleaning mechanism, the cleaning liquid in the water tank is sprayed out from multiple nozzles through the liquid pipe under the guidance of a water pump. Based on the setting of the annular guide rail, the back of the drilled PET substrate can be turned upward after drilling. In the inverted state, the debris generated by drilling naturally separates from the hole wall under the action of gravity, and the scouring resistance of high-pressure water flow is reduced, thereby effectively improving the cleaning efficiency. At the same time, after the substrate is turned over, the cleaning liquid is injected from the back of the substrate to directly impact the accumulation surface of the residue in the hole, thereby avoiding secondary blockage caused by the backflow of debris at the outlet during forward cleaning.

[0010] In a preferred embodiment, the clamping mechanism further comprises: a cavity provided on one inner wall of the top frame, wherein a slot is provided through the inner wall of the cavity, the slot facing the inner side of the top frame; and a member rotatably connected to two opposite inner walls of the cavity around an axis; The clamping mechanism further includes: two torsion springs, respectively sleeved on the outer walls of both ends of the winding shaft, with one end of the torsion spring fixedly connected to the outer wall of the winding shaft and the other end of the torsion spring fixedly connected to the inner wall of one side of the cavity; a fiber cloth, wound around the outer circumference of the winding shaft, with one end fixedly connected to the outer wall of one side of the winding shaft; The clamping mechanism further includes: a metal hook fixedly connected to the other end of the fiber cloth; a second magnetic sheet fixedly connected to an inner wall of one side of the top frame and located on the same side as the notch, with one end of the fiber cloth passing through the notch, and the metal hook magnetically adsorbed to the outside of the second magnetic sheet; a hanging rack fixedly connected to the top outer wall of the top frame, and the metal hook hung on the hanging rack; and a sticker attached to both the PET substrate and the bottom outer wall of the top frame. The drying mechanism comprises: a drying box body, each of which is divided into two parts, and the two parts are connected by a hinge and a buckle, and the bottom outer walls of the two parts of the drying box body are respectively fixedly connected to rollers; two hot air blowers are fixedly embedded in the inner walls of the drying box body on opposite sides, and the air outlets of the hot air blowers face the interior of the drying box body; The drying mechanism also includes: multiple horizontal plates, which are equidistantly and symmetrically fixed to the inner wall of the drying box, and the multiple horizontal plates correspond to the air outlet positions of the two hot air blowers respectively; multiple hooks are respectively set through the multiple horizontal plates, and a handle can be hung on each hook.

[0011] By providing a clamping mechanism and a drying mechanism, in the drying mechanism, hot air is blown out by multiple hot air blowers, and the hot air temperature is controlled at a low temperature and slow drying. After the drilling is completed, when manually unloading the material, the fiber cloth can be manually unfolded and covered on the outside of the circuit distribution surface of the PET substrate. Finally, the top frame is hung on each hook and low-temperature slow drying is carried out in the drying box. Under this structure, the fiber cloth covering can prevent hot air from directly blowing on the circuit distribution surface during the drying process, reducing thermal shock damage and homogenizing the heat field distribution. At the same time, based on low-temperature and slow drying, deformation or delamination caused by thermal stress can be avoided for flexible substrates with poor heat resistance such as PET, effectively ensuring the quality of the PET substrate.

[0012] As can be seen from the above, a PET substrate drilling device includes a stand, and also includes: a drilling mechanism connected to the top inner wall of the stand; an annular guide rail, arranged at the bottom end of the drilling mechanism, and a partition is fixedly connected to the middle position of the annular guide rail; a clamping mechanism, arranged at the bottom end of the drilling mechanism and movably connected to the annular guide rail; a cleaning mechanism, located between the plurality of clamping mechanisms; a drying mechanism, located on one side of the drilling mechanism; the drilling mechanism includes: two sets of multi-dimensional guide rails, fixedly connected to the top inner wall of the stand in parallel; an ultraviolet laser The optical instrument is movably connected to one of the multidimensional guide rails; the micro-drilling machine is movably connected to the other multidimensional guide rail; the first vacuum insulation panel is fixedly connected to the top inner wall of the stand and is located between the two sets of multidimensional guide rails; the second vacuum insulation panel has two hinged rods fixedly connected at each end, and the second vacuum insulation panel is hinged to the bottom end of the first vacuum insulation panel via the hinged rods. The outer walls of the first vacuum insulation panel and the second vacuum insulation panel are respectively coated with a thermal insulation coating; the weight block is fixedly embedded in the bottom inner wall of the second vacuum insulation panel. The PET substrate drilling equipment provided by the present invention has the technical effect of minimizing hole position deviation and achieving optimized drilling accuracy.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The PET substrate drilling device disclosed in the present invention is mainly used in the scenario of drilling holes in PET substrates.

[0024] Reference Figure 1-Figure 3 , a PET substrate drilling device, including a stand 6, further comprising: The drilling mechanism 1 is connected to the inner wall of the top end of the stand 6; The annular guide rail 2 is provided at the bottom end of the drilling mechanism 1, and a partition plate 7 is fixedly connected to the middle position of the annular guide rail 2; The clamping mechanism 5 is provided at the bottom end of the drilling mechanism 1 and is movably connected to the annular guide rail 2; A cleaning mechanism 8 is located between the plurality of clamping mechanisms 5; The drying mechanism 4 is located on one side of the drilling mechanism 1; The drilling mechanism 1 comprises: Two sets of multi-dimensional guide rails 101 are fixedly connected in parallel to the top inner wall of the stand 6; The ultraviolet laser instrument 103 is movably connected to one of the multi-dimensional guide rails 101; The micro-drilling machine 102 is movably connected to another multi-dimensional guide rail 101, wherein the annular guide rail 2 drives multiple PET substrates to translate and sequentially pass through the UV laser 103 and the micro-drilling machine 102. The UV laser 103 first pre-opens a guide hole to provide a physical guide channel for the mechanical drill bit of the micro-drilling machine 102, eliminating the lateral slippage of the mechanical drill bit during initial contact. The laser pre-opening forms a rigid constraint, forcing the drill bit to feed along a preset path, greatly compressing the hole position deviation, thereby optimizing the drilling accuracy. At the same time, when the micro-drilling machine 102 is cutting, the laser pre-opening has removed most of the material, reducing the drill bit cutting amount and significantly reducing frictional heat, thereby protecting and extending the drill bit life. The vacuum insulation panel 104 is fixedly connected to the top inner wall of the stand 6 and is located between the two sets of multi-dimensional guide rails 101; The second vacuum insulation panel 107 has two hinge rods 106 fixedly connected at both ends, and the second vacuum insulation panel 107 is hinged to the bottom end of the first vacuum insulation panel 104 via the hinge rods 106. The outer walls of the first vacuum insulation panel 104 and the second vacuum insulation panel 107 are respectively coated with a thermal insulation coating 105; The weight block 108 is fixedly embedded in the inner wall of the bottom end of the vacuum insulation panel 107. Based on the setting of the vacuum insulation panel 104 and the vacuum insulation panel 107, and the coating of the thermal insulation coating 105, an effective heat radiation isolation effect can be achieved. The high temperature generated by the drill cutting is radiated or conducted to the laser optical path system, which will cause the laser focus drift and wavelength shift, reducing the processing accuracy. The setting of the thermal insulation structure can directly block the heat radiation conduction and shorten the setting distance between the ultraviolet laser 103 and the micro drill drilling machine 102, thereby reducing the footprint of the device and reducing construction costs. Based on the hinged structure of the hinged rod 106 and the gravity guidance of the weight block 108, the clamping mechanism 5 can be driven to bend by contacting the vacuum insulation panel 107 during the translation process, thereby ensuring the thermal insulation effect during the processing while not hindering the translation of the PET substrate.

[0025] Reference Figure 4 and Figure 5 In a preferred embodiment, the clamping mechanism 5 includes: Two limit frames 505 are fixedly connected to the outer wall of the partition 7, and the two limit frames 505 are respectively located directly below the micro drill bit drilling machine 102 and the ultraviolet laser instrument 103; The two bases 503 are movably sleeved on the outside of the two limit frames 505, and springs 504 are fixedly connected between the limit frames 505 and the bases 503; Multiple through-holes 510 are respectively provided on the top outer wall of each base 503 and correspond to the drilling positions of the substrate. Based on the setting of the spring 504, when the slide 508 moves, the chamfer 506 contacts the two sides of the base 503, which drives the spring 504 to compress until the base 503 is located at the position of the square through-groove 509. The base 503 bounces up and fits against the bottom of the PET substrate, which can avoid displacement of the PET substrate during the drilling process and will not affect subsequent cleaning.

[0026] Reference Figure 4 In a preferred embodiment, the clamping mechanism 5 further comprises: A plurality of slides 508 are movably connected to the annular guide rail 2; A square through-slot 509 is provided at the center of the bottom end of the slide 508 , and chamfers 506 are provided on both sides of the square through-slot 509 , through which the base 503 passes; The C-shaped limit frame 507 is fixedly connected to the top outer wall of the slide 508 and is located on both sides of the square through slot 509 .

[0027] Reference Figure 4 In a preferred embodiment, the clamping mechanism 5 further comprises: The top frame 502 is attached to the top outer wall of the slide 508, and the C-shaped limit frame 507 is movably attached to the outer periphery of the top frame 502; The handle 501 is fixedly connected to the top outer wall of the top frame 502; The magnetic sheet 513 is fixedly attached to the bottom outer wall of the top frame 502 and the top outer wall of the slide 508, and the top frame 502 and the slide 508 are magnetically adsorbed by the magnetic sheet 513, and the bottom outer wall of the PET substrate is just flush with the bottom end of the magnetic sheet 513 at the bottom of the top frame 502.

[0028] Reference Figure 1 and Figure 6 In a preferred embodiment, the cleaning mechanism 8 includes: The liquid pipe 802 is fixedly connected to the partition 7 through a plurality of limit brackets 803, and its input end passes through the partition 7 and is fixedly connected to the water tank 805. A water pump is fixedly installed at the connection between the liquid pipe 802 and the water tank 805; The mounting frame 804 is sleeved on the outside of the water tank 805 and fixedly connected to the stand 6; Multiple nozzles 801 are fixedly connected to multiple output ends of the liquid pipe 802, and the pressure of the multiple nozzles 801 is set in increasing order; The liquid collecting tank 3 is arranged at the bottom end of the multiple nozzles 801. In the cleaning mechanism 8, the cleaning liquid in the water tank 805 is sprayed out from the multiple nozzles 801 through the liquid pipe 802 under the guidance of the water pump. Based on the setting of the annular guide rail 2, the PET substrate that has been drilled can be transferred to the bottom end after drilling, and the back of the PET substrate faces upward. The setting of the square through groove 509 in the clamping mechanism 5 can expose the back of the PET substrate after drilling, so that the cleaning liquid can act on the PET substrate smoothly. In the inverted state, the debris generated by drilling is removed by gravity. The water can naturally detach from the hole wall and reduce the scouring resistance of high-pressure water flow, effectively improving the cleaning efficiency. At the same time, the cleaning liquid is injected from the back of the substrate after flipping, directly impacting the accumulation surface of the residue in the hole, avoiding secondary blockage caused by the backflow of debris at the outlet during forward cleaning. In addition, the pressure of multiple nozzles 801 is set in an incremental manner. The low-pressure initial flushing loosens the surface pollutants, and the high-pressure final flushing ensures the penetration of the channel, realizing the layer-by-layer peeling of residues with different adhesion strengths, effectively improving the cleaning uniformity. At the same time, compared with the constant high-pressure mode, the stepped pressure design can reduce the power consumption of the water pump.

[0029] Reference Figure 8 In a preferred embodiment, the clamping mechanism 5 further comprises: A cavity 511 is provided on an inner wall of one side of the top frame 502 , and a notch 512 is provided through the inner wall of one side of the cavity 511 , with the notch 512 facing the inner side of the top frame 502 ; The housing 510 is rotatably connected to the inner walls of the cavity 511 on two opposite sides around the axis 516 .

[0030] Reference Figure 8 In a preferred embodiment, the clamping mechanism 5 further comprises: Two torsion springs 517 are respectively sleeved on the outer walls of the winding shaft 516 at both ends, with one end of the torsion spring 517 fixedly connected to the outer wall of the winding shaft 516, and the other end of the torsion spring 517 fixedly connected to the inner wall of one side of the cavity 511; The fiber cloth 514 is wound around the outer periphery of the winding shaft 516, and one end thereof is fixedly connected to the outer wall of one side of the winding shaft 516. After the drilling is completed, when manually unloading, the top frame 502 can be directly removed to disengage the magnetic piece 1 513, and then the fiber cloth 514 is pulled out through the metal hook 518. Based on the setting of the magnetic piece 2, the position of the metal hook 518 can be fixed when the fiber cloth 514 is wound to avoid affecting the normal drilling. During the winding process of the fiber cloth 514, the torsion springs 517 at both ends can be set to make the fiber cloth 514 stably wrapped around the winding shaft 516. Then, the metal hook 518 can be manually clamped on the hanger 519 to unfold the fiber cloth 514 and cover the outside of the circuit distribution surface of the PET substrate.

[0031] Reference Figure 8 In a preferred embodiment, the clamping mechanism 5 further comprises: A metal hook 518 is fixedly connected to the other end of the fiber cloth 514; Magnetic sheet 2 is fixedly connected to the inner wall of one side of top frame 502 and is located on the same side as notch 512. One end of fiber cloth 514 passes through notch 512. Metal hook 518 is magnetically attached to the outside of magnetic sheet 2. A hanger 519 is fixedly connected to the top outer wall of the top frame 502, and a metal hook 518 is hung on the hanger 519; The sticker 515 is simultaneously adhered to the PET substrate and the outer wall of the bottom end of the top frame 502. The setting of the sticker 515 can first fix the PET substrate at the bottom end of the top frame 502, thereby realizing priority preparation, facilitating the magnetic loading and installation of the PET substrate, and also preventing the PET substrate from falling during the drying process.

[0032] Reference Figure 7 In a preferred embodiment, the drying mechanism 4 includes: The drying box 401 is divided into two parts, and the connection between the two parts is connected by hinges and buckles. The outer walls of the bottom ends of the two parts of the drying box 401 are respectively fixedly connected with rollers; Two hot air blowers 404 are fixedly embedded in the inner walls on opposite sides of the drying box 401, and the air outlets of the hot air blowers 404 face the interior of the drying box 401. In the drying mechanism 4, hot air is blown out by multiple hot air blowers 404, and the hot air temperature is controlled at a low temperature of 60-80℃ for slow drying.

[0033] Reference Figure 7 In a preferred embodiment, the drying mechanism 4 further comprises: Multiple horizontal plates 403 are symmetrically and equidistantly fixed to the inner wall of the drying box 401, and the multiple horizontal plates 403 correspond to the air outlet positions of the two hot air blowers 404 respectively; Multiple hooks 402 are respectively arranged on multiple horizontal plates 403, and a handle 501 can be hung on each hook 402. Finally, the top frame 502 is hung on each hook 402, and the drying box 401 is combined to perform low-temperature slow drying. Under this structure, the fiber cloth 514 is covered to prevent hot air from directly blowing on the line distribution surface during the drying process, reducing thermal shock damage and uniformizing the heat field distribution. At the same time, based on low-temperature slow drying, deformation or delamination caused by thermal stress can be avoided for flexible substrates with poor heat resistance such as PET, effectively ensuring the quality of the PET substrate.

[0034] Working principle: The annular guide rail 2 drives multiple PET substrates to translate and pass through the UV laser 103 and the micro drill drilling machine 102 in sequence. The UV laser 103 first pre-opens a guide hole to provide a physical guide channel for the mechanical drill bit of the micro drill drilling machine 102, eliminating the lateral slippage of the mechanical drill bit during initial contact. The laser pre-opening forms a rigid constraint, forcing the drill bit to feed along the preset path, and compressing the hole position deviation to the greatest extent, thereby optimizing the drilling accuracy. At the same time, when the micro drill drilling machine 102 is cutting, the laser pre-opening has removed most of the material, the drill bit cutting amount is reduced, and the friction heat is significantly reduced, thereby protecting and extending the drill bit life. In addition, based on the setting of vacuum insulation panel 1 104 and vacuum insulation panel 2 107 , and the coating of the thermal insulation coating 105 can achieve an effective heat radiation isolation effect. The high temperature generated by the drill cutting is radiated or conducted to the laser optical path system, which will cause the laser focus drift and wavelength shift, reducing the processing accuracy. The setting of the thermal insulation structure can directly block the heat radiation conduction, and can shorten the setting distance between the ultraviolet laser 103 and the micro-drill drilling machine 102, thereby reducing the footprint of the device and reducing construction costs. Based on the hinged structure of the hinged rod 106 and the gravity guidance of the load-bearing block 108, the vacuum insulation board 2 107 can be driven to bend during the translation process of the clamping mechanism 5, thereby ensuring the thermal insulation effect during the processing while not hindering the translation of the PET substrate.
