Description

Technical Field

[0001] The present application relates to the technical field of punching and blanking of flexible circuit boards, and in particular to a punching and blanking device for flexible circuit boards. Background Art

[0002] Flexible printed circuit board, referred to as FPC (Flexible Printed Circuit), is also called soft circuit board or flexible circuit board. FPC is popular for its excellent properties such as light weight, thin thickness, and free bending and folding.

[0003] FPC embeds circuit design on a bendable thin plastic sheet, allowing a large number of precision components to be stacked in a small and limited space to form a bendable flexible circuit. During the processing, a punch press is generally required to punch the long FPC into multiple sections of specified lengths, thereby facilitating subsequent cutting and processing.

[0004] During the punching process of existing flexible circuit boards, it is necessary to use a robot or other means to cut and collect the punched flexible circuit boards. However, the above method requires the installation of a robot on each punch press, which is costly. When the robot is used to perform cutting operations between different punch presses, the robot needs to move back and forth, and the movement is slow. It is difficult to meet the punching speed requirements and the efficiency is low. Summary of the invention

[0005] The present application provides a blanking device for punching a flexible circuit board, which can solve the problem of low efficiency when using a robot to blank materials on two punching machines, and high cost of repeatedly setting up multiple robots on the production line.

[0006] The technical solution of the present application is as follows: A blanking device for punching a flexible circuit board is arranged between two opposite punching machines and performs blanking, comprising: Two unloading platform assemblies, the two unloading platform assemblies are respectively arranged on two punching machines, and are used to carry flexible circuit boards; A placement trough body, wherein the placement trough body is arranged between two relatively arranged punching machines, a reciprocating drive assembly is arranged on the placement trough body, and feeding claw assemblies are arranged at intervals on both sides of the reciprocating drive assembly, and the reciprocating drive assembly can drive the feeding claw assembly to move back and forth between the placement trough body and the punching machine to take out the flexible circuit boards on the two punching machines, and two storage grooves for storing flexible circuit boards are arranged inside the placement trough body, and the storage grooves are located one by one below the feeding claw assemblies, and a rockable bottom plate is arranged inside the storage grooves, and when the reciprocating drive assembly drives the feeding claw assembly to move, it can also drive the bottom plate to rock.

[0007] By adopting the above scheme, the reciprocating drive assembly is used to drive the unloading claw assembly to move back and forth between the two punching machines, so that the unloading assembly can simultaneously complete the material picking and unloading functions of the two punching machines in one stroke, and put the punched flexible circuit board into the storage slot, thereby improving the efficiency of material picking and unloading between the two punching machines. At the same time, when the reciprocating drive assembly is in motion, it can drive the bottom plate inside the storage slot to shake, and through shaking, the flexible circuit boards recovered on the top of the bottom plate can be sorted to avoid uneven stacking of the flexible circuit boards, which may cause wrinkles during the recycling process.

[0008] In one embodiment of the present application, the unloading platform assembly includes: A mounting frame, the mounting frame being detachably mounted on the punch press; A placing plate, wherein the placing plate is mounted on the mounting frame, wherein one side of the placing plate is located at one side of the cutter of the punch press, and the other side extends to the outside of the punch press, wherein at least two strip openings are provided inside the placing plate, and at least two of the strip openings are spaced apart on the placing plate, and the unloading claw assembly can reciprocate at the strip opening along the length direction of the strip opening.

[0009] By adopting the above scheme, the mounting frame is arranged on one side of the cutter of the punch press, so that when the flexible circuit board enters the placement plate, it will not affect the punch press cutter to punch and cut the flexible circuit board. At this time, the flexible circuit board is placed on the unloading claw assembly. When the unloading claw assembly moves and moves away from the strip opening, it can drive the flexible circuit board out of the punch press together, thereby completing the material collection and unloading of the flexible circuit board.

[0010] In one embodiment of the present application, the reciprocating drive assembly includes: A driving frame, the driving frame is vertically arranged and fixedly assembled on the placement slot body, a driving motor is arranged on the driving frame, a moving slot is opened at the upper end of the driving frame, a rack is slidably connected inside the moving slot, a driving shaft of the driving motor is coaxially fixedly assembled with a driving gear, and the driving gear is meshed with the rack; A driving rod, one end of which is fixedly assembled on one side of the rack, and the unloading claw assembly is arranged on the driving rod at intervals along the length direction of the driving rod.

[0011] By adopting the above scheme, when the driving motor drives the driving gear to rotate in different directions, the driving gear can drive the rack to reciprocate inside the moving groove, thereby driving the driving rod to reciprocate, and the driving rod can drive the unloading claw assemblies located on both sides thereof to approach or move away from the punch press, and by reciprocating between the two opposite punch presses, the device can complete the action of taking and unloading materials for the two punch presses within one stroke; In addition, as the rack continuously moves back and forth inside the movable groove, when the rack moves to the end of its stroke, it can hit the groove wall of the movable groove, and the vibration effect generated by the impact can be transmitted to the bottom plate of the storage groove, thereby causing the bottom plate to shake, thereby making the punched flexible circuit boards placed on the bottom plate more evenly stacked.

[0012] In one embodiment of the present application, the reciprocating drive assembly includes: A placement rack, the placement rack is fixedly mounted on one side of the upper end of the placement tank; A linear module is arranged on the placement rack, a slide table of the linear module is fixedly connected to a moving rod, and the unloading claw assembly is arranged on the moving rod at intervals along the length direction of the moving rod.

[0013] By adopting the above solution, the linear module can also drive the moving rod to move back and forth between the two punching machines, thereby driving the unloading claw assemblies located on both sides of the moving rod to move, and unloading the flexible circuit boards that have been punched on the punching machine. In addition, when the slide of the linear module moves to the end of the stroke, the collision generated when the slide moves to the end can also drive the bottom plate to shake, so that the flexible circuit boards can be stacked more tightly.

[0014] In one embodiment of the present application, the feeding claw assembly includes at least two feeding rods, and at least two of the feeding rods correspond one-to-one to at least two strip openings. One end of the feeding rod is fixedly mounted on the driving rod or the moving rod, and the other end extends toward the corresponding strip opening.

[0015] By adopting the above solution, when the driving rod or the moving rod drives the unloading rod to move back and forth, the unloading rod can move back and forth inside the strip opening along the length direction of the strip opening, thereby improving the convenience of the unloading rod in taking and unloading materials.

[0016] In one embodiment of the present application, the feed rod comprises: A connecting section, one end of which is fixedly mounted on the driving rod and the other end of which extends in the direction of the strip-shaped opening; A curved connecting section, one end of which is fixedly assembled to the other end of the connecting section along a vertical direction, a connecting opening is provided at the lower end of the curved connecting section, and the other end of the curved connecting section extends along the length direction of the connecting section; A deflection bar, wherein the deflection bar is located at the opening, one end of which is rotatably assembled on the other end of the curved connecting section through a hinge, and the other end of which is provided with an arc-shaped notch and can be turned over in the vertical direction at the opening; A tail rod, one end of which is fixedly assembled on the other end of the curved connecting section.

[0017] By adopting the above scheme, when the feed rod enters the strip-shaped opening, the flexible circuit board can enter the curved connecting section and be located on the upper surface of the deflection bar. When the punching of the flexible circuit board is completed, the feed rod moves away from the strip-shaped opening. At this time, the deflection bar automatically deflects due to gravity, and the flexible circuit board located on the deflection bar automatically falls into the storage groove, thereby completing the collection of the flexible circuit board.

[0018] In one embodiment of the present application, the length D of the opening and the width L of the flexible circuit board satisfy: L <D。

[0019] By adopting the above solution, the length of the opening is limited so that the flexible circuit board can move into the opening of the curved connecting section without causing spatial interference.

[0020] In one embodiment of the present application, a hollow cavity is provided inside the deflection strip on a side away from the arc-shaped notch.

[0021] By adopting the above solution, a hollow cavity is opened on one side of the deflection bar, so that the weight on both sides of the deflection bar is inconsistent, and the center of the deflection bar is offset toward the arc-shaped notch, so that after the deflection bar is separated from the punch press, it can automatically deflect downward and place the flexible circuit board into the storage groove.

[0022] In one embodiment of the present application, the bottom plate is tilted downward toward a side close to the reciprocating drive assembly, an elastic rubber ring is provided between the bottom plate and the receiving groove, a fluid cavity is formed between the bottom plate and the bottom of the receiving groove, and a fluid medium is provided inside the fluid cavity.

[0023] By adopting the above solution, when the base plate is set on the fluid medium and the reciprocating drive assembly is at the end of the stroke, the vibration generated is transmitted to the fluid medium, causing the fluid medium to shake, thereby driving the base plate to shake, so that the flexible circuit board located above the base plate continues to shake, making the flexible circuit board more compact when stacked.

[0024] In one embodiment of the present application, one side of the bottom plate is rotatably mounted on a side wall of two receiving grooves close to each other, the bottom plate is tilted downward toward the side close to the reciprocating drive assembly, and the other side can be flipped in a vertical direction inside the receiving groove, and an elastic member is provided between the bottom plate and the bottom of the receiving groove.

[0025] By adopting the above solution, when the base plate is set on the elastic member, when the reciprocating drive assembly is at the end of the stroke, the vibration generated is transmitted to the elastic member, causing the elastic member to vibrate, thereby driving the base plate to flip and vibrate, which can also make the flexible circuit board more compact when stacked.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the unloading table assembly and the reciprocating drive assembly to cooperate with each other, the reciprocating drive assembly can move back and forth between the two punches, and the reciprocating drive assembly can drive the unloading claw assembly to approach or move away from the placement plate. When approaching the placement plate and moving to the end of the stroke, the flexible circuit board can just enter the opening under the curved connecting rod and be located on the upper surface of the deflection bar. When away from the placement plate, the deflection bar automatically flips downward, and the flexible circuit board enters the storage groove. By setting the action frequency of the two punches, the two unloading claws can unload the flexible circuit boards on the two punches at the same time when they move back and forth.

[0027] 2. By setting up a reciprocating drive assembly, when the reciprocating drive assembly moves to the end of the stroke, the impact can generate vibration, the vibration can be transmitted to the bottom plate, and cause the bottom plate to shake. When the bottom plate shakes, it can drive the flexible circuit board located above the bottom plate to vibrate and shake continuously, so that the flexible circuit board is more tightly stacked and will not bend.

[0028] 3. By setting a deflection bar with an offset center of gravity, when the deflection bar is out of cooperation with the punch press, the mass of the side of the deflection bar away from the punch press is greater than the mass of the other side, so the deflection bar can be flipped faster, thereby making the flexible circuit board unloading speed faster.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-9 The present application provides a blanking device for punching a flexible circuit board, which is arranged between two opposite punching machines 4 and performs blanking, and comprises: two blanking table assemblies 1 and a placement trough 2.

[0032] Example 1 See also Figure 1 , Figure 2 and Figure 3 The two unloading platform assemblies 1 are respectively arranged on two punching machines 4, and are used to carry the flexible circuit board 3; See also Figure 6 The unloading table assembly 1 includes: a mounting frame 11 and a placement plate 12, the mounting frame 11 is detachably mounted on the punch 4, the placement plate 12 is mounted on the mounting frame 11, one side of the placement plate 12 is located at one side of the cutter of the punch 4, and the other side extends to the outside of the punch 4, at least two strip openings 121 are opened inside the placement plate 12, and at least two of the strip openings 121 are arranged at intervals on the placement plate 12, and the unloading claw assembly 22 can reciprocate at the strip opening 121 along the length direction of the strip opening 121, and by arranging the placement plate 12 on the punch 4 where unloading is required, and by opening the strip opening 121 on the placement plate 12, the unloading claw assembly 22 can cooperate to enter, so that the flexible circuit board 3 can move and reach the unloading claw assembly 22.

[0033] The placement trough body 2 is arranged between two punching machines 4 arranged opposite to each other, and a reciprocating drive component 21 is arranged on the placement trough body 2, and a feeding claw component 22 is arranged at intervals on both sides of the reciprocating drive component 21. The reciprocating drive component 21 can drive the feeding claw component 22 to move back and forth between the placement trough body 2 and the punching machine 4 to take out the flexible circuit boards 3 on the two punching machines 4. Two storage grooves 23 for storing flexible circuit boards 3 are arranged inside the placement trough body 2, and the storage grooves 23 are located one by one below the feeding claw component 22. A rocking bottom plate 231 is arranged inside the storage groove 23. When the reciprocating drive component 21 drives the feeding claw component 22 to move, the bottom plate 231 can also be driven to rock. By utilizing the feeding claw component 22 that can reciprocate and move the feeding claw Relative punches 4 are arranged on both sides of the component 22. When the reciprocating drive component 21 drives the unloading claw component 22 to reciprocate, the already punched flexible circuit boards 3 on the punches 4 on both sides can be taken out and unloaded into the storage groove 23, so that in one stroke, two punches 4 can be unloaded at the same time, thereby improving the effect of automatic unloading. In addition, when the reciprocating drive component 21 drives the flexible circuit board 3 to move, at the end of the moving stroke, the vibration generated by the impact can drive the bottom plate 231 inside the storage groove 23 to shake, thereby causing the flexible circuit board 3 located on the bottom plate 231 to vibrate and shake continuously, thereby improving the precision of the flexible circuit board 3 when stacking, so that even if the flexible circuit board 3 bends during the unloading process, it can be placed flat by shaking.

[0034] In this embodiment, a belt conveyor can also be provided on one side of the two punching machines 4, and the unpunched flexible circuit board 3 is sent to the inside of the punching machine 4 through the belt conveyor 5, thereby completing the automatic loading; A power supply device and a controller may also be provided, and the power supply device is electrically connected to the reciprocating drive assembly 21, the punching machine 4 and the transmission belt conveyor through the controller, so that the device can perform automatic punching. The above-mentioned electrical connection method is a conventional technical means in the prior art, so it will not be described in detail here.

[0035] See also Figure 3The reciprocating drive assembly 21 includes: a drive frame 211 and a drive rod 213. The drive frame 211 is vertically arranged and fixedly assembled on the placement slot 2. A drive motor 212 is arranged on the drive frame 211. A moving slot 2111 is opened at the upper end of the drive frame 211. A rack 2112 is slidably connected inside the moving slot 2111. A drive gear 2121 is coaxially fixedly assembled on the drive shaft of the drive motor 212. The drive gear 2121 is meshed with the rack 2112. One end of the drive rod 213 is fixedly assembled on the rack 2 On one side of 112, the feeding claw assembly 22 is arranged on the driving rod 213 at intervals along the length direction of the driving rod 213, and the driving motor 212 drives the driving gear 2121 to rotate, so that the rack 2112 can reciprocate inside the movable groove 2111, so that it can drive the feeding claw assembly 22 to reciprocate. At the same time, the rack 2112 can hit the movable groove 2111, and the vibration generated can also drive the bottom plate 231 to shake, so that the flexible circuit board 3 will not be wrinkled or bent during the feeding and stacking process, and the flexible circuit board 3 can be stacked more compactly.

[0036] See also Figure 3 and Figure 6 The unloading claw assembly 22 includes at least two unloading rods 221, and at least two of the unloading rods 221 correspond to at least two strip openings 121 one by one. One end of the unloading rod 221 is fixedly assembled on the driving rod 213 or the moving rod 216, and the other end extends to the corresponding strip opening 121. By setting two unloading claws, in the process of the reciprocating driving assembly 21 driving the unloading claw to reciprocate between the two punching machines 4, the unloading claw can take out the punched flexible circuit board 3 that moves above it, and automatically release the flexible circuit board 3 above the storage groove 23. In one stroke, the flexible circuit boards 3 on the two punching machines 4 can be taken and unloaded at the same time, thereby improving the unloading efficiency of the device.

[0037] See also Figure 6, the blanking rod 221 includes: a connecting section 2211, a curved connecting section 2212, a deflecting strip 2213, and a tail rod 2214. One end of the connecting section 2211 is fixedly assembled on the driving rod 213, and the other end extends toward the strip-shaped opening 121. One end of the curved connecting section 2212 is fixedly assembled vertically on the other end of the connecting section 2211. An opening 2215 is provided at the lower end of the curved connecting section 2212. The other end of the curved connecting section 2212 extends along the length direction of the connecting section 2211. The deflecting strip 2213 is located at the opening 2215. One end is rotatably assembled on the other end of the curved connecting section 2212 through a hinge 2216, and the other end is provided with an arc-shaped notch 2217 and can be flipped vertically at the opening 2215. One end of the tail rod 2214 is fixedly assembled on the other end of the curved connecting section 2212. By providing the blanking rod 221 with the opening 2215, when the blanking rod 221 enters the strip-shaped opening 121, the flexible circuit board 3 can move above the deflecting strip 2213 at the opening 2215. When the blanking rod 221 exits the strip-shaped opening 121, one end of the deflecting strip 2213 with the arc-shaped notch 2217 automatically deflects due to losing the contact with the punching machine 4, and the flexible circuit board 3 on the deflecting strip 2213 automatically falls into the storage groove 23, thereby improving the convenience of the device blanking.

[0038] Please continue to refer to Figure 6 , the length D of the opening 2215 and the width L of the flexible circuit board 3 satisfy: L < D. By limiting the length of the opening 2215, the flexible circuit board 3 can smoothly enter the opening 2215 of the curved connecting section 2212 on the blanking rod 221 during the feeding process.

[0039] Please refer to Figure 7 , a hollow cavity 2218 is provided on the side of the deflecting strip 2213 away from the arc-shaped notch 2217. By making one side of the deflecting strip 2213 hollow, the mass of the side of the deflecting strip 2213 away from the arc-shaped notch 2217 is lighter, the center of gravity of the strip rod is offset, the deflection speed of the deflecting strip 2213 after leaving the strip-shaped opening 121 is increased, and the blanking speed is faster.

[0040] Please refer to Figure 8The bottom plate 231 is tilted downward toward a side close to the reciprocating drive assembly 21, an elastic rubber ring 232 is provided between the bottom plate 231 and the receiving groove 23, a fluid cavity 233 is formed between the bottom plate 231 and the bottom of the receiving groove 23, a fluid medium 234 is provided inside the fluid cavity 233, and by providing the fluid medium 234, when the reciprocating drive assembly 21 reciprocates to the end of the stroke, the impact generated can drive the fluid medium 234 to shake, so that the bottom plate 231 shakes continuously during the unloading process, so that even if the flexible circuit board 3 is bent during unloading, it can be stacked flatly on the bottom plate 231 through shaking.

[0041] Example 2 See also Figure 4 and Figure 5 The structure of Example 2 is basically the same as that of Example 1, except that: the reciprocating drive assembly 21 includes: a placement frame 214 and a linear module 215, the placement frame 214 is fixedly assembled on one side of the upper end of the placement trough body 2, the linear module 215 is arranged on the placement frame 214, the slide of the linear module 215 is fixedly connected with a moving rod 216, and the unloading claw assembly 22 is arranged on the moving rod 216 at intervals along the length direction of the moving rod 216. By setting the linear module 215, the linear module 215 can also drive the moving rod 216 to move, thereby driving the unloading claw assembly 22 to reciprocate. During the movement, the flexible circuit boards 3 on the two punching machines 4 are unloaded synchronously, and the vibration generated by moving to the end of the stroke is used to drive the bottom plate 231 to shake, so that the flexible circuit boards 3 are more compact when stacked.

[0042] Example 3 See also Fig. 9 The structure of Example 3 is basically the same as that of Example 1, except that: one side of the bottom plate 231 is rotatably assembled on the side wall of the two receiving grooves 23 close to each other, the bottom plate 231 is tilted downwardly toward the side close to the reciprocating drive assembly 21, and the other side can be flipped in the vertical direction inside the receiving groove 23, and an elastic member 235 is provided between the bottom plate 231 and the bottom of the receiving groove 23. By providing the elastic member 235, when the reciprocating drive assembly 21 moves to the end of the stroke, the impact generated can also drive the elastic member 235 to vibrate, thereby driving the bottom plate 231 to vibrate continuously, so that the flexible circuit board 3 falling on the bottom plate 231 is stacked more flatly.

[0043] In this embodiment, the elastic member 235 may be a columnar spring or a metal spring.

[0044] In summary, when it is necessary to unload the flexible circuit board 3 on the two relatively arranged punching machines 4, the driving motor 212 can drive the driving gear 2121 to rotate. By controlling the rotation direction of the driving motor 212, the rack 2112 can reciprocate inside the moving groove 2111, and drive the unloading claw assembly 22 to reciprocate into the punching machine 4, and the flexible circuit board 3 enters above the deflection bar 2213. The punching machine 4 moves, and the flexible circuit board 3 entering above the deflection bar 2213 is cut by the cutter. At this time, the driving motor 212 reverses and drives the deflection away from the strip opening 121. When the deflection bar 2213 is out of contact with the punching machine 4, the deflection bar 2213 automatically deflects, and the flexible circuit board 3 located above it automatically falls into the receiving groove 23. The actions of the two punching machines 4 are staggered, and the unloading operation is performed alternately, thereby improving the unloading efficiency of the device; At the same time, when the unloading claw assembly 22 moves back and forth and moves to the end of the stroke, an impact will occur. The vibration caused by the impact can cause the bottom plate 231 to shake, so that when the flexible circuit board 3 falls on the bottom plate 231, even if it bends, it can still be flattened in time through shaking, so that the flexible circuit board 3 is more compact when stacked.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
