Description

Technical Field

[0001] This utility model belongs to the field of FPC board processing technology, specifically relating to a drilling device and an FPC board processing device. Background Technology

[0002] Flexible printed circuit boards (FPCs) are the simplest type of flexible circuit board, mainly used for connecting with other circuit boards. FPCs are generally classified as single-layer boards, double-layer boards, multi-layer boards, and double-sided boards. During the manufacturing process of FPCs, holes need to be drilled into their surface.

[0003] Existing drilling equipment generally cannot fix FPC boards of different sizes, which brings great inconvenience to the drilling process of FPC boards. At the same time, the position of the drill bit usually needs to be constantly adjusted during drilling to drill holes at different points, which is very inconvenient to operate and results in low drilling efficiency of FPC boards.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a drilling device and an FPC board processing device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a drilling device and an FPC board processing device, which can solve the problem that existing drilling devices cannot adapt to fixed drilling of FPC boards of different sizes.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A drilling device includes: an operating table, a drilling slot, two pairs of sliding grooves, a drilling mechanism, and a fixing mechanism.

[0009] A keel frame is fixed to the operating platform. The drilling slot and two pairs of sliding grooves are drilled on the operating platform, with the drilling slot located below the keel frame. The pair of sliding grooves are located on both sides of the drilling slot and are perpendicular to the drilling slot. The drilling mechanism slides on the keel frame.

[0010] The fixing mechanism is mounted on the operating table and includes: two pairs of sliders, two pairs of bases, two pairs of arc-shaped pressure plates, and a locking assembly. The two pairs of sliders slide in two pairs of grooves. The two pairs of bases are fixed to the sliders, and each base has a pair of L-shaped support arms fixed to it. A fixing shaft is fixed between the ends of the L-shaped support arms furthest from the base. The two pairs of arc-shaped pressure plates rotate on the fixing shaft, and a torsion spring is installed between the fixing shaft and the arc-shaped pressure plates. The locking assembly is installed between the arc-shaped pressure plates and the pair of L-shaped support arms to lock the arc-shaped pressure plates.

[0011] In one embodiment of this utility model, a slide rail is provided on the keel frame, and the drilling mechanism slides on the slide rail. The drilling mechanism is slidably positioned between itself and the keel frame by sliding on the slide rail.

[0012] In one embodiment of this invention, each of the two pairs of sliding grooves has a sliding rod fixed therein, and the slider slides on the sliding rod. The slider slides in the sliding groove via the sliding rod.

[0013] In one embodiment of this utility model, a fixing seat and a connector are respectively fixed to the bottom of a pair of crossbeams. A first lead screw is installed between the fixing seat and the connector. The first lead screw is rotatably connected to the fixing seat and threadedly connected to the connector. One end of the first lead screw outside the fixing seat is used to connect to an external driving device, so that the driving device drives the first lead screw to rotate. Through the rotation of the first lead screw, the first lead screw drives the pair of crossbeams to move closer to each other through the connector. The pair of crossbeams move the bases on them through two pairs of sliders, thereby clamping the FPC board between the two pairs of bases.

[0014] In one embodiment of this utility model, a crossbeam is fixed between the two pairs of sliders, and a second lead screw is rotatably mounted on the bottom of the operating table. The second lead screw is threadedly connected to one of the crossbeams. One end of the second lead screw is located outside the operating table and is used to connect to an external drive device. The drive device drives the second lead screw to rotate, which in turn moves one of the crossbeams. The crossbeam, through the first lead screw, simultaneously drives the other crossbeam to rotate, thereby moving the FPC board on it to the position where drilling is required.

[0015] In one embodiment of this utility model, a soft rubber pad is also fixed on the base. The soft rubber pad is used to prevent the FPC board from being damaged due to excessive clamping force.

[0016] In one embodiment of this utility model, an arc-shaped guide plate is fixed to the end of the arc-shaped pressure plate away from the fixed axis, and an arc-shaped slide rail adapted to the arc-shaped guide plate is fixed to the inner wall of each pair of L-shaped support arms. The arc-shaped guide plate is used to assist the arc-shaped pressure plate in clamping the FPC board.

[0017] In one embodiment of this utility model, the arc axis of the arc guide plate and the arc slide rail are the same as the axis of the fixed shaft, so that when the arc pressure plate rotates about the fixed shaft, the arc guide plate slides in the arc slide rail.

[0018] In one embodiment of this utility model, the locking assembly includes: a rotating shaft, multiple slots, a pair of locking blocks, and a control rod. The rotating shaft rotates on a pair of L-shaped support arms and is located on one side of an arc-shaped guide plate. The multiple slots are evenly carved into the arc-shaped guide plate. The pair of locking blocks are fixed on both sides of the rotating shaft and are engaged in the arc-shaped guide plate. The control rod is fixed to one end of the rotating shaft located outside the L-shaped support arms, and an elastic locking plate is fixed to the outer wall of the L-shaped support arms.

[0019] When the FPC board needs to be clamped and fixed, after pushing the FPC board between the base and the arc-shaped pressure plate, the control rod drives the rotating shaft to rotate and locks the control rod onto the elastic clamping plate. When the rotating shaft rotates, it drives the clamping block to rotate. When the rotating shaft drives the clamping block to rotate, it causes the clamping block to lock into the clamping groove. At the same time as the clamping block rotates, its lower bottom wall abuts against the inner bottom wall of the clamping groove. In this way, the clamping block locks the arc-shaped guide plate, thereby locking the arc-shaped pressure plate and preventing it from loosening.

[0020] When it is necessary to release the FPC board, first press the elastic clamp inward, then rotate the control lever outward. When the control lever drives the rotating shaft to rotate 180 degrees, the rotating shaft rotates the clamp at one end out of the clamping slot, and drives the clamp at the other end to rotate from the bottom of the rotating shaft into another clamping slot, so that the upper top wall of the clamping block abuts against the upper side wall of the clamping slot. Then continue to drive the rotating shaft to rotate through the control lever. At this time, the rotating shaft lifts the arc-shaped guide plate upward through the clamping block. The arc-shaped guide plate drives the arc-shaped pressure plate upward. At this time, the FPC board can be removed from between the base and the arc-shaped pressure plate.

[0021] This utility model also discloses an FPC board processing device, including a drilling device.

[0022] Compared with the prior art, the drilling device and FPC board processing device of this utility model effectively improve the drilling efficiency of FPC boards through related structural design. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0032] like Figures 1 to 5 As shown, a drilling device according to one embodiment of the present invention includes: an operating table 1, a drilling groove 104, two pairs of sliding grooves 105, a drilling mechanism 103, and a fixing mechanism 2.

[0033] like Figures 1 to 5 As shown, a keel frame 101 is fixed on the operating platform 1. A drilling slot 104 and two pairs of sliding grooves 105 are drilled on the operating platform 1, with the drilling slot 104 located below the keel frame 101, and the pair of sliding grooves 105 located on both sides of the drilling slot 104, perpendicular to the drilling slot 104. The drilling mechanism 103 slides on the keel frame 101.

[0034] like Figures 1 to 5 As shown, the fixing mechanism 2 is installed on the operating table 1. The fixing mechanism 2 includes: two pairs of sliders 203, two pairs of bases 204, two pairs of arc-shaped pressure plates 208, and a locking assembly. The two pairs of sliders 203 slide in the two pairs of slide grooves 105 respectively. The two pairs of bases 204 are fixed on the sliders 203 respectively, and each base 204 is fixed with a pair of L-shaped support arms 206. A fixing shaft 207 is fixed between the ends of the pair of L-shaped support arms 206 away from the bases 204. The two pairs of arc-shaped pressure plates 208 rotate on the fixing shaft 207 respectively, and a torsion spring 209 is installed between the fixing shaft 207 and the arc-shaped pressure plates 208. The locking assembly is installed between the arc-shaped pressure plates 208 and the pair of L-shaped support arms 206 to lock the arc-shaped pressure plates 208.

[0035] In use, the FPC board is first inserted between a pair of bases 204 and an arc-shaped pressure plate 208. Upon insertion, the FPC board pushes the arc-shaped pressure plate 208 upwards. After the FPC board is inserted between the bases 204 and the arc-shaped pressure plate 208, the torsion spring 209 first presses the arc-shaped pressure plate 208 firmly onto the bases 204. Then, the locking assembly locks the arc-shaped pressure plate 208 to prevent loosening of the pressure on the FPC board. Next, the other pair of bases 204 is slid to the other side of the FPC board, clamping it onto the other side of the FPC board in the same manner.

[0036] When drilling, the FPC board is slid to move the position where the FPC board needs to be drilled to the drilling slot 104. Then, the drilling mechanism 103 is controlled by an external control device to slide on the keel frame 101 and move to the drilling position to drill.

[0037] like Figures 1 to 5 As shown, a slide rail 102 is provided on the keel frame 101, and a drilling mechanism 103 slides on the slide rail 102. The drilling mechanism 103 slides between itself and the keel frame 101 by sliding on the slide rail 102. A slide rod 201 is fixed in each of the two pairs of slide grooves 105, and a slider 203 slides on the slide rod 201. The slider 203 slides in the slide groove 105 via the slide rod 201.

[0038] like Figures 1 to 5As shown, a pair of crossbeams 202 are respectively fixed to a base 217 and a connector 218 at their bottoms. A first lead screw 219 is installed between the base 217 and the connector 218. The first lead screw 219 is rotatably connected to the base 217 and threadedly connected to the connector 218. One end of the first lead screw 219 outside the base 217 is used to connect to an external drive device, which drives the first lead screw 219 to rotate. Through the rotation of the first lead screw 219, the first lead screw 219 drives the pair of crossbeams 202 to move closer to each other via the connector 218. The pair of crossbeams 202 move the bases 204 on them via two pairs of sliders 203, thereby clamping the FPC board between the two pairs of bases 204.

[0039] like Figures 1 to 5 As shown, a crossbeam 202 is fixed between two pairs of sliders 203. A second lead screw 220 is rotatably mounted on the bottom of the operating platform 1, and the second lead screw 220 is threadedly connected to one of the crossbeams 202. One end of the second lead screw 220 is located outside the operating platform 1 for connecting to an external drive device. The drive device drives the second lead screw 220 to rotate, which in turn drives one of the crossbeams 202 to move. The crossbeam 202, through the first lead screw 219, simultaneously drives the other crossbeam 202 to rotate, thereby moving the FPC board on it to the position where drilling is required.

[0040] like Figures 1 to 5 As shown, a soft rubber pad 205 is also fixed on the base 204. The soft rubber pad 205 is used to prevent damage to the FPC board due to excessive clamping force. An arc-shaped guide plate 210 is fixed to the end of the arc-shaped pressure plate 208 away from the fixed shaft 207. Arc-shaped slide rails 211 that are adapted to the arc-shaped guide plate 210 are fixed on the inner walls of a pair of L-shaped support arms 206. The arc-shaped guide plate 210 is used to assist the arc-shaped pressure plate 208 in clamping the FPC board. The arc axis of the arc-shaped guide plate 210 and the arc-shaped slide rail 211 are the same axis as the axis of the fixed shaft 207, so that when the arc-shaped pressure plate 208 rotates around the fixed shaft 207, the arc-shaped guide plate 210 slides within the arc-shaped slide rail 211.

[0041] like Figures 1 to 5 As shown, the locking assembly includes: a rotating shaft 213, multiple slots 212, a pair of locking blocks 216, and a control lever 214. The rotating shaft 213 rotates on a pair of L-shaped support arms 206 and is located on one side of the arc-shaped guide plate 210. The multiple slots 212 are evenly carved into the arc-shaped guide plate 210. The pair of locking blocks 216 are fixed on both sides of the rotating shaft 213 and are engaged in the arc-shaped guide plate 210. The control lever 214 is fixed to one end of the rotating shaft 213 located outside the L-shaped support arms 206, and an elastic locking plate 215 is fixed on the outer wall of the L-shaped support arms 206.

[0042] When the FPC board needs to be clamped and fixed, the FPC board is pushed between the base 204 and the arc-shaped pressure plate 208. The control rod 214 drives the rotating shaft 213 to rotate and locks the control rod 214 onto the elastic clamping plate 215. When the rotating shaft 213 rotates, it drives the clamping block 216 to rotate. When the rotating shaft 213 drives the clamping block 216 to rotate, it drives the clamping block 216 to lock into the clamping groove 212. While the clamping block 216 is rotating, its lower bottom wall abuts against the inner bottom wall of the clamping groove 212. Thus, the clamping block 216 locks the arc-shaped guide plate 210, thereby locking the arc-shaped pressure plate 208 and preventing it from loosening.

[0043] When it is necessary to release the FPC board, first press the elastic clamping plate 215 inward, then rotate the control lever 214 outward. When the control lever 214 drives the rotating shaft 213 to rotate 180 degrees, the rotating shaft 213 rotates the clamping block 216 at one end out of the clamping slot 212, and drives the clamping block 216 at the other end to rotate from the bottom of the rotating shaft 213 into another clamping slot 212, so that the upper top wall of the clamping block 216 abuts against the upper side wall of the clamping slot 212. Then continue to drive the rotating shaft 213 to rotate through the control lever 214. At this time, the rotating shaft 213 lifts the arc-shaped guide plate 210 upward through the clamping block 216. The arc-shaped guide plate 210 drives the arc-shaped pressure plate 208 upward. At this time, the FPC board can be removed from between the base 204 and the arc-shaped pressure plate 208.

[0044] This utility model also discloses an FPC board processing device, which includes the aforementioned drilling device.

[0045] Working principle: Before using this device, one end of the first lead screw 219 and the second lead screw 220 needs to be connected to an external drive device to drive the first lead screw 219 and the second lead screw 220 to rotate. During drilling, firstly, one side of the FPC board is inserted between a pair of bases 204 and the arc-shaped pressure plate 208. When the FPC board is inserted, it pushes the arc-shaped pressure plate 208 to rotate upward. After the FPC board is inserted between the base 204 and the arc-shaped pressure plate 208, the spring force of the torsion spring 209 first causes the arc-shaped pressure plate 208 to press the FPC board firmly onto the base 204.

[0046] Subsequently, the control lever 214 drives the rotating shaft 213 to rotate, and the control lever 214 is locked onto the elastic plate 215. When the rotating shaft 213 rotates, it drives the locking block 216 to rotate. When the rotating shaft 213 drives the locking block 216 to rotate, the locking block 216 is locked in the slot 212. While the locking block 216 is rotating, its lower bottom wall abuts against the inner bottom wall of the slot 212. Thus, the locking block 216 locks the arc-shaped guide plate 210, thereby locking the arc-shaped pressure plate 208 and preventing it from loosening.

[0047] Then, the first lead screw 219 is driven to rotate by an external drive device. The first lead screw 219 drives a pair of crossbeams 202 to move closer together through the connector 218. The pair of crossbeams 202 move the bases 204 on them through two pairs of sliders 203. This slides the other pair of bases 204 to the other side of the FPC board, so that they are clamped to the other side of the FPC board in the same way.

[0048] When drilling, the second lead screw 220 is driven to rotate by an external drive device. The second lead screw 220 drives one of the crossbeams 202 to move, thereby causing the FPC board to slide and move the FPC board to the drilling slot 104. Then, the drilling mechanism 103 is controlled by an external control device to slide on the keel frame 101 and move to the drilling position to drill.

[0049] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description.
