Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the drawings of the present invention are in simplified form and are not to scale precisely, but rather are merely intended to facilitate a clear and concise description of embodiments of the present invention.
As shown in fig. 1 to 2, the present invention provides a full-automatic uncoiling laser cutting production line, comprising: the three-in-one leveling feeder 10, the single-head flat cutter 20, the first double-head flat cutter 40, the waste conveyor 50, the second double-head flat cutter 60 and the palletizing platform 70 are sequentially arranged. Further, a truss robot 30 is disposed above the first dual-head plane cutter 40 and the second dual-head plane cutter 60, and the truss robot 30 alternately carries the plate material and the finished product on the first dual-head plane cutter 40 and the second dual-head plane cutter 60.
With continued reference to fig. 1 and 2, the three-in-one leveler feeder 10 includes: an unwinding mechanism 110, a feeding mechanism 120 provided corresponding to the unwinding mechanism 110, and a leveling mechanism 130 mounted on the feeding mechanism 120. Specifically, the three-in-one leveling feeder 10 is used for uncoiling, leveling and feeding a material belt, i.e. feeding the uncoiled material belt to the next process.
Referring to fig. 3 and 4, the single-head flat cutting machine 20 includes: the cutting head 210 is a laser cutting head, which is installed above the material belt supporting frame 230 and has a degree of freedom in the X/Y/Z direction, so that the cutting head can move randomly within the area of the material belt supporting frame 230 and cut the material belt at the position. The saw tooth mechanism 220 is disposed below the material belt supporting frame 230 and is capable of lifting, and the conveying roller table 240 is disposed at a discharge end of the material belt supporting frame 230, and is used for conveying the material belt.
With continued reference to fig. 3 and 4, the material belt supporting frame 230 includes a supporting frame body 231, two sets of rotating rollers mounted on the supporting frame body 231 and symmetrically arranged, and a turning mechanism (not shown in the drawings) for controlling the turning of the rotating rollers. Further, the rotating roller includes a rotating rod 232 located at the edge of the supporting frame body 231 and connected to the turnover mechanism, and a plurality of rotating rollers 233 mounted on the rotating rod 232. Specifically, one end of the rotating roller 233 is rotatably connected to the rotating rod 232, the other end of the rotating roller 233 is suspended, and the turning mechanism can turn the rotating roller 233 by 90 ° by adjusting the rotating rod 232. Namely, the rotating rod 232 has two states, one is that the rotating roller 233 is located on the horizontal plane for supporting the material belt, and the other is that the rotating roller 233 is turned over by 90 ° by the turning mechanism to be turned vertically downward after the material belt is conveyed, so that the damage of high-temperature splash slag when the rotating roller 233 is cut by laser can be avoided. Preferably, the rotating rollers are two groups symmetrically arranged, so that the space required for turning is small, the work of the saw tooth mechanism 220 is not affected, and the turned rotating rollers 233 are just positioned at two sides of the inside of the supporting frame body 231, so that the saw tooth mechanism 220 is abdied.
Referring to fig. 3 with emphasis, the saw tooth mechanism 220 includes a lifting saw tooth table 221 and a lifting mechanism 222 for controlling the lifting saw tooth table 221 to lift, wherein a plurality of saw tooth plates 2210 are distributed on the lifting saw tooth table 221 at equal intervals, and the saw tooth plates 2210 are staggered with the rotating roller 233.
Referring to fig. 5, in another alternative embodiment, the saw tooth mechanism 220 includes a turning saw tooth stage 2220 and a turning mechanism for controlling the turning saw tooth stage 2220 to rotate, and a plurality of saw tooth plates 2210 are distributed on the turning saw tooth stage 2220 at equal intervals, and the saw tooth plates 2210 are staggered with the rotating roller 233.
In this embodiment, the general structure of the tape supporting frame 230 may refer to the above embodiment. That is, in the tape conveying process, the rotating rod 223 is turned upwards to a horizontal position to support the tape, and after the tape conveying is completed, the rotating rod 223 is turned downwards to a vertical direction, so that the cutting is prevented from being damaged.
The driving mode of the overturning saw-tooth table 2220 is the same as that of the overturning material receiving roller table. During the tape transport, the serrated plate 2210 of the inverted serrated station 2220 is inverted to a horizontal position so that the tape is placed thereon when cut. When the cutting is completed, the overturning saw-tooth table 2220 is quickly overturned downwards, so that the waste left on the overturning saw-tooth table 2220 is quickly overturned by 90 degrees and quickly falls on the conveyor belt of the waste conveyor below, thereby correspondingly adapting the feeding rate of the feeding mechanism 120, the working efficiency of the single-head plane cutter 20, the cutting efficiency of the two double-head plane cutters (40, 60), the working efficiency of the waste discharge and the working efficiency of the finished product of the stacking platform 70 and maintaining a higher working beat.
As a result of many studies and creative findings by the present inventors, the reason for limiting the application of laser cutting is not only the speed of laser head cutting but also a logistic limitation mainly consisting of the flow of waste/raw materials/finished products. Therefore, the rapid waste discharge, rapid raw material feeding, rapid finished product removal, and final product dimensional accuracy determination due to the web positioning accuracy, the fact that the saw tooth plate 2210 cannot scratch the surface of the finished product is a main concern, and the rapid laser cutting, namely, the high-processing beat operation of the whole machine, can be realized after the above problems are solved.
Referring to fig. 1 and 2, the first dual head flat cutter 40 and the second dual head flat cutter 60 each include a rotary saw table 430, and a left cutting head 410 and a right cutting head 420 mounted above the rotary saw table 430. Likewise, the left and right cutting heads 410 and 420 have degrees of freedom in the x\y\z direction, and laser cutting can be performed on the tape at any position on the surface of the rotary saw blade 430.
Further, the cutting heads of the first dual head planar cutter 40 and the second dual head planar cutter 60 may be shared. That is, since the first and second double- head plane cutters 40,60 are alternately operated, the left and right cutting heads 410, 420 may be operated to and fro between the first and second double- head plane cutters 40, 60.
Preferably, the rotating saw-tooth platforms 430 in the first double-head planar cutter 40 and the second double-head planar cutter 60 rotate in opposite directions and both rotate in the direction of the scrap conveyor 50, and the scrap conveyor 50 is located between the rotating saw-tooth platforms 430 of the two sets of double-head planar cutters and is responsible for receiving the scrap discharged from the rotating saw-tooth platforms 430 and transporting the scrap from the sides of the whole line into the scrap box.
In another alternative embodiment, the specific structure of the rotary saw blade stage 430 in the first dual head planar cutter 40 and the second dual head planar cutter 60 may also refer to the structure of the inverted saw blade stage 2220 of the single head planar laser cutter.
Referring with emphasis to fig. 1, the truss robot 30 includes: truss 330, first truss robot 310 and second truss robot 320 located on truss 330 and moving along truss 330, wherein truss 330 covers the area where single-headed planar cutter 20, first double-headed planar cutter 40, scrap conveyor 50, second double-headed planar cutter 60 and palletizing platform 70 are located. Specifically, the first truss manipulator 310 is responsible for grabbing and transporting the cut sheet material to the tables of the first and second double- head plane cutters 40 and 60, and the second truss manipulator 320 is responsible for grabbing and transporting the finished parts cut on the tables of the first and second double- head plane cutters 40 and 60 to the palletizing platform 70.
Referring to fig. 1 to 4, the working process of the present invention is:
when the three-in-one flat-open feeder 10 is about to feed, the rotating roller 233 in the material belt supporting frame 230 is driven by the turning mechanism and the rotating rod 232, the turning is positioned on the horizontal plane, and the upper surface of the rotating roller 233 is higher than the elevation of the elevating saw-tooth table 221.
When the material belt is fed to a certain length, the three-in-one flat-open feeding machine 10 stops feeding, the lifting saw-tooth table 221 is jacked up by the lifting mechanism 222 to contact the material belt, and meanwhile, the rotating roller 233 can be turned to the vertical direction, and the cutting head 210 cuts the material belt according to the discharging.
Then, the first truss manipulator 310 grabs the cut-end material strip plate and conveys the material strip plate to the table top of the first double-head plane cutter 40, then the material strip plate is returned to the original point to convey the material strip plate to the table top of the second double-head plane cutter 60 again, after the first double-head plane cutter 40 completes cutting, the left cutting head 410 and the right cutting head 420 come to the second double-head plane cutter 60, meanwhile, the second truss manipulator 320 comes to the table top of the first double-head plane cutter 40 to grab a finished product and convey the finished product to the stacking platform 70 for stacking, at the same time, the first double-head plane cutter 40 starts to discharge waste, the second double-head plane cutter 60 starts to work, the two double-head plane cutters alternately cut and discharge waste, and the two groups of truss manipulators alternately convey the plate material and the finished product, so that the high-efficiency production beat is ensured.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
