Description

Technical Field

[0001] The invention belongs to the technical field of aluminum foil circuit board processing, and in particular relates to a die-cutting device used for aluminum foil circuit board processing. Background Art

[0002] Due to the soaring copper price, aluminum has become an important substitute for copper and has also become a trend in the manufacture of printed circuit boards. With the expansion of the application of flexible printed circuit boards, the application of aluminum foil in flexible printed circuit boards has also become possible. When making circuit boards, it is first necessary to die-cut the aluminum foil through a die-cutting device as required. The existing die-cutting equipment used for processing aluminum foil circuit boards cannot well control the die-cutting and winding process through a simple linkage structure. When the die-cutting machine body die-cuts the aluminum foil, the upper die-cutting tool and the lower die-cutting tool will clamp the aluminum foil. If the winding device continues to wind the aluminum foil tape at this time, the aluminum foil tape will be torn off. In addition, the die-cut aluminum foil profile is not easy to separate from the aluminum foil tape. The aluminum foil profile will hang on the aluminum foil tape, which is not convenient for collecting the die-cut aluminum foil profile. Summary of the invention

An aluminum foil winding device 6 is fixedly provided on the top of the conveying module 2 below the pressing member 5. A contact delay device 7 is fixedly provided on the top of the aluminum foil winding device 6. During the die-cutting process of the aluminum foil by the die-cutting machine body 1, the connecting plate 3 can be used to carry The dynamic buffer protection member 4 and the pressing member 5 are lifted and pressed to open the die-touch delayer 7. When the die-cutting machine body 1 drops to the lowest point to complete a die-cutting operation and the upper die-cutting tool thereon starts to rise and separate from the lower die-cutting tool, the die-touch delayer 7 will control the aluminum foil rewinding device 6 to start rotating to rewind the die-cut aluminum foil tape. After reaching the set time on the die-touch delayer 7, the die-touch delayer 7 automatically controls the aluminum foil rewinding device 6 to stop rotating, and the time set on the die-touch delayer 7 is less than the time taken for the upper die-cutting tool to open and close. Before the upper die-cutting knife contacts the lower die-cutting knife, the aluminum foil rewinding device 6 has stopped rewinding and rotating, that is, the die-cutting machine body 1 can die-cut each pair of aluminum foil without tearing the aluminum foil strip. The aluminum foil rewinding device 6 rewinds the die-cut aluminum foil strip once. The front side of the aluminum foil rewinding device 6 is connected to a gear driving member 8. An impact stripping module 9 is provided at one end of the gear driving member 8. The impact stripping module 9 is fixedly installed on one side of the top end of the aluminum foil rewinding device 6. During the rewinding process, the aluminum foil strip rewinding roller 60 on the aluminum foil rewinding device 6 3 can drive the gear driving member 8 to rotate, and the rotation of the gear driving member 8 can drive the impact stripping module 9 to rise. When the impact stripping module 9 rises to a certain height, the gear driving member 8 is separated from the impact stripping module 9. At this time, the impact stripping module 9 will quickly reset by using its own specific structure, and the die-cut aluminum foil profiles on the aluminum foil belt can be pushed off from the aluminum foil belt. The aluminum foil profiles pushed off from the aluminum foil belt will fall onto the conveying module 2, and the die-cut aluminum foil profiles can be automatically conveyed and collected by the conveying module 2;

Guide roller groups 12 are symmetrically fixed on both sides of the die-cutting machine body 1. An aluminum foil winding length metering component is provided between the gear driving component 8 and the impact stripping module 9. The aluminum foil winding length metering component consists of an infrared measuring device 14, a reflector 15 and a counter. When the aluminum foil strip is wound by the aluminum foil winding device 6, the length of the wound aluminum foil strip can be measured by the linked aluminum foil winding length metering component.

When the gear driving component 8 rotates, the sawtooth structure can be used to drive the sawtooth plate 903 on the impact stripping module 9 to rise. When the sawtooth plate 903 on the impact stripping module 9 rises to a certain height, the gear driving component 8 is separated from the sawtooth plate 903. At this time, the sawtooth plate 903 will be quickly reset under the rebound of the spring reset component 905. During the rapid reset of the sawtooth plate 903, the impact component 906 can be driven to move downward through the connecting rod. The downward movement of the impact component 906 can push the die-cut aluminum foil profile on the aluminum foil strip off the aluminum foil strip.

The top of the impact plate 909 is located on the outside of the bottom end of the T-shaped rod member 908 and is sleeved with a buffer spring member 9010. The buffer spring member 9010 on the impact member 906 makes the impact plate 909 have good buffering performance, which can prevent the impact plate 909 from violently hitting the aluminum foil strip and causing damage to the aluminum foil strip when it moves downward to impact the aluminum foil profile.

The buffer protection member 4 can be used to safely protect the touch mold delay 7, and damage to the touch mold delay 7 can be avoided when the pressing member 5 presses down the touch mold delay 7.

[0032] refer to Figure 1 and Figure 2As shown, the aluminum foil winding device 6 includes a frame 601, a winding motor 602, an aluminum foil tape winding roller 603 and an elastic clamping member 604. The elastic clamping members 604 are symmetrically arranged on both sides of the inner cavity of the frame 601. The elastic clamping members 604 on the left and right sides are respectively fixedly connected to the winding motor 602 and the gear driving member 8. When the die-cutting machine body 1 drops to the lowest point to complete a die-cutting and the upper die-cutting tool thereon starts to rise and separate from the lower die-cutting tool, the die-touch delay 7 will control the winding motor 602 on the aluminum foil winding device 6 to start rotating to rewind the die-cut aluminum foil tape. After reaching the set time on the die-touch delay 7, the die-touch delay 7 automatically controls the winding motor 602 on the aluminum foil winding device 6 to stop rotating.

The spacing between the mounting plate 901 and the gear driving member 8 is greater than the length of the gear driving member 8. The spacing between the mounting plate 901 and the gear driving member 8 is greater than the length of the gear driving member 8, so that the mounting plate 901 will not affect the rotation of the gear driving member 8. When the gear driving member 8 rotates, the serration plate 903 on the impact stripping module 9 can be driven to rise by utilizing the serration structure. When the serration plate 903 on the impact stripping module 9 rises to a certain height, the gear driving member 8 is separated from the serration plate 903. At this time, the serration plate 903 will quickly reset under the rebound of the spring reset member 905. Every rotation of the gear driving member 8 will drive the serration plate 903 on the impact stripping module 9 to rise once, thereby completing the top loading of the aluminum foil profile.

[0035] refer to Figure 1 and Figure 2As shown, the infrared measuring device 14 and the reflecting member 15 are respectively fixedly mounted on the bottom of the mounting plate 901 and the outer side of one end of the gear driving member 8.

The number of rotations of the aluminum foil tape winding roller 603 can be counted through the counter, and the winding length of the aluminum foil tape can be indirectly measured according to the number of rotations of the aluminum foil tape winding roller 603. When the winding length of the aluminum foil tape reaches the set value, the data processing and control system will automatically control the aluminum foil winding device 6 to stop the winding work, so that the aluminum foil tape can be quantitatively wound.

[0037] Working principle: In the process of die-cutting the aluminum foil through the die-cutting machine body 1, the buffer protection part 4 and the pressing part 5 can be driven to rise and fall by the connecting plate 3 to press and open the touch-die delay 7. When the die-cutting machine body 1 drops to the lowest point to complete a die-cutting and the upper die-cutting tool thereon starts to rise and separate from the lower die-cutting tool, the touch-die delay 7 will control the aluminum foil rewinding device 6 to start rotating and rewind the die-cut aluminum foil strip. After reaching the set time on the touch-die delay 7, the touch-die delay 7 automatically controls the aluminum foil rewinding device 6 to stop rotating, and the time set on the touch-die delay 7 is less than the time taken by the upper die-cutting tool to open and close. Before the upper die-cutting tool contacts the lower die-cutting tool, the aluminum foil rewinding device 6 has stopped rewinding and rotating, that is, each time the die-cutting machine body 1 die-cuts a pair of aluminum foil, the aluminum foil rewinding device 6 rewinds the die-cut aluminum foil strip once;

[0038] During the winding process, the aluminum foil winding roller 603 on the aluminum foil winding device 6 can drive the gear driving member 8 to rotate, and the rotation of the gear driving member 8 can drive the impact stripping module 9 to rise. When the impact stripping module 9 rises to a certain height, the gear driving member 8 is separated from the impact stripping module 9. At this time, the impact stripping module 9 will quickly reset using its own specific structure, and the die-cut aluminum foil profiles on the aluminum foil strip can be pushed off from the aluminum foil strip. The aluminum foil profiles pushed off from the aluminum foil strip will fall onto the conveying module 2, and the die-cut aluminum foil profiles can be automatically conveyed and collected by the conveying module 2;

[0039] The infrared signal emitted by the infrared measuring device 14 can be reflected by the reflecting member 15, so that the infrared measuring device 14 will receive the infrared signal emitted by itself once every time the aluminum foil winding roller 603 rotates, and output a pulse signal to trigger the counting circuit. The number of rotations of the aluminum foil winding roller 603 can be counted by the counter, and the winding length of the aluminum foil can be indirectly measured according to the number of rotations of the aluminum foil winding roller 603. When the winding length of the aluminum foil reaches the set value, the data processing and control system will automatically control the aluminum foil winding device 6 to stop winding, and the aluminum foil can be quantitatively wound. The aluminum foil guiding mechanism 10 can monitor the aluminum foil in real time through the wire break monitoring module 11 during the guiding process of the aluminum foil. When the aluminum foil breaks during the die-cutting process, the data processing controller will control the alarm 1105 to turn on and issue an alarm reminder in time, so as to facilitate the discovery of problems and maintenance. At the same time, the data processing controller will also control the wireless transmission module to send the fault to the remote terminal, so as to facilitate timely maintenance.
