Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a visual positioning automatic cutting machine. Background Art

[0002] Cutting machines, also known as cutting machines, die-cutting machines, etc., have been widely used in punching materials such as leather, plastic, cloth, FPC, copper foil, and cover film to make them meet the cutting size of the processed products.

[0003] Among the existing patents, the Chinese patent document with application number 202321009625.5 discloses an automatic visual recognition cutting machine, including a material feeding device, a material clamping device, a material cutting device and a control device; the material clamping device is arranged between the material feeding device and the material cutting device; the material cutting device includes a cutting bracket, a translation frame, a front and rear translation mechanism, a translation seat, a left and right translation mechanism, a knife die cutting mechanism and a visual recognition mechanism; the knife die cutting mechanism includes a lower pressure plate, a cutting lifting mechanism, a knife die assembly, and a rotary drive mechanism; the visual recognition mechanism is installed on the translation seat and is located in front of the knife die assembly, and the visual recognition mechanism includes at least a visual camera, and the shooting area of ​​the visual camera corresponds to the conveying surface of the material clamping device. The automatic visual recognition cutting machine can automatically identify the patterns and codes printed on the material to be cut, and automatically adjust the cutting position of the die assembly accordingly to achieve more accurate cutting and blanking. However, it only pulls the material backward through the material clamping device. After the die cutting mechanism completes one cutting, the material clamping device can release the material and then move forward and reset to prepare for the next material pulling. This method of pulling the material is inefficient and is not conducive to improving cutting production efficiency.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

The lifting driver is used to drive the lifting seat and the driven roller to move closer to or away from the active roller, and the table surface of the material supporting platform is tangent to the top of the active roller.

[0014] Furthermore, a guide roller is rotatably connected to a side of the supporting platform away from the roller conveying mechanism.

[0015] Furthermore, the pressing and cutting mechanism includes a pressing and cutting seat installed on the machine, a knife seat connected to the pressing and cutting seat in a lifting and sliding manner, an upper cutting knife installed on the knife seat, a lower cutting knife installed on the pressing and cutting seat and located below the upper cutting knife, a cutting driver installed on the top of the pressing and cutting seat and used to drive the knife seat to lift and lower, a lower pressing plate installed on the pressing and cutting seat and located on the feed side of the lower cutting knife, an upper pressing plate arranged on one side of the knife seat and located above the lower pressing plate, and a support plate installed on the pressing and cutting seat and located on the discharge side of the lower cutting knife.

[0027] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0028] like Figures 1 to 7As shown, the utility model provides a visual positioning automatic cutting machine, which includes a machine platform 1, a visual positioning mechanism 2, a first pulling device 3, a second pulling device 4 and a reeling mechanism 5, a supporting table 6, a roller conveying mechanism 7, a pressing and cutting mechanism 8 and a stacking bin 9 which are sequentially installed on the machine platform 1. The pulling end of the first pulling device 3 and the pulling end of the second pulling device 4 are both moved and arranged above the stacking bin 9. The second pulling device 4 is located on the side of the first pulling device 3 away from the pressing and cutting mechanism 8. The visual positioning mechanism 2 is installed on the machine platform 1 and is located above the supporting table 6. The supporting table 6 is used to support the material sheet released by the reeling mechanism 5. The roller conveying mechanism 7 is used to convey the material sheet. The first pulling device 3 is used to pull the material sheet at the discharge side of the pressing and cutting mechanism 8. The second pulling device 4 is used to receive and pull the material sheet on the first pulling device 3. Specifically, the pulling speed of the first pulling device 3, the pulling speed of the second pulling device 4 and the conveying speed of the roller conveying mechanism 7 are equal, and the material can be FPC, copper foil, covering film, cloth or film material, etc.

[0029] In actual application, the material roll is installed on the unwinding mechanism 5, and the material sheet in the material roll passes through the material supporting platform 6, the roller conveying mechanism 7 and the pressing and cutting mechanism 8 in turn. The unwinding mechanism 5 releases the material sheet in the material roll, and the roller conveying mechanism 7 conveys the material sheet to move the material sheet. At the same time, the visual positioning mechanism 2 visually identifies the mark on the material sheet, and the pulling end of the first pulling device 3 clamps the material sheet on the discharge side of the pressing and cutting mechanism 8 and pulls the material sheet to ensure that the moving material is straight. When the first pulling device 3 pulls the material sheet to a preset length, the second pulling device 4 clamps the material sheet pulled by the first pulling device 3 and takes over the pulling of the material sheet. When the visual positioning mechanism 2 visually recognizes the mark, it proves that the material sheet has been pulled to the required length to ensure the required cutting of the material. The sheet is fixed in length, and the visual positioning mechanism 2 feeds back signals to the second pulling device 4, the roller conveying mechanism 7 and the pressing and cutting mechanism 8, so that the second pulling device 4 stops pulling the sheet, the roller conveying mechanism 7 stops conveying the sheet, the pressing and cutting mechanism 8 presses and cuts the sheet, and the second pulling device 4 releases the sheet, so that the cut sheet is stacked in the stacking bin 9; when the second pulling device 4 pulls the sheet, the first pulling device 3 resets to the discharge side of the pressing and cutting mechanism 8 to prepare for the next pulling of the sheet, that is, while the sheet is still being pulled by the second pulling device 4, the first pulling device 3 can reset to the starting position to prepare for the next pulling of the sheet, and the first pulling device 3 and the second pulling device 4 work independently without affecting each other. In addition, when the length of the required cutting sheet is within the pulling range of the first pulling device 3, the second pulling device 4 is not needed. Only the first pulling device 3 is needed to pull the sheet. The user can selectively use the second pulling device 4 according to the actual situation to meet the needs of cutting sheets of different lengths. It is flexible to use and highly practical. The utility model ensures fixed-length cutting through visual positioning, and adopts a connecting rod-type pulling sheet (two-stage / connecting pulling sheet) through the first pulling device 3 and the second pulling device 4, shortening the pulling stroke and waiting time of the first pulling device 3, improving the efficiency of pulling the sheet, thereby improving the cutting production efficiency, and the user can selectively use the second pulling device 4 according to the actual cutting needs.

[0030] In this embodiment, the first pulling device 3 includes a first translation drive mechanism 10 installed on the machine 1 and located on one side of the stacking bin 9, a crossbar 11 installed on the translation end of the first translation drive mechanism 10, and two first clamping assemblies 12 installed on the crossbar 11 in a relative and spaced relationship. The two first clamping assemblies 12 are used to clamp the two sides of the material sheet. In actual application, the two first clamping assemblies 12 respectively clamp the material sheet at the discharge side of the pressing and cutting mechanism 8. The first translation drive mechanism 10 drives the crossbar 11 to move away from the pressing and cutting mechanism 8. The moving crossbar 11 drives the two first clamping assemblies 12 to pull the material sheet to move, making the moving material sheet straight.

[0031] In this embodiment, the first clamping assembly 12 includes a first clamping driver 13 mounted on the crossbar 11 and two first clamping blocks 14 mounted on the two clamping ends of the first clamping driver 13. The first clamping driver 13 is used to drive the two first clamping blocks 14 toward and away from each other. The two first clamping blocks 14 are arranged in a corresponding manner above and below. Specifically, the first clamping driver 13 can be a finger cylinder. In actual use, the first clamping driver 13 drives the two first clamping blocks 14 toward each other until they clamp the material sheet; the first clamping driver 13 drives the two first clamping blocks 14 away from each other until they release the material sheet.

[0032] In this embodiment, the second pulling device 4 includes a second translation drive mechanism 15 installed on the machine 1 and located on one side of the stacking bin 9, a connecting arm 16 installed on the translation end of the second translation drive mechanism 15, and two second clamping components 17 installed parallel to the connecting arm 16. The two second clamping components 17 are located between the two first clamping components 12. In actual application, when the first pulling device 3 pulls the material to a preset length, the two second clamping components 17 clamp the ends of the material pulled by the first pulling device 3, and then the first pulling device 3 releases the material. The second translation drive mechanism 15 drives the connecting arm 16 to continue to move in the direction away from the pressing and cutting mechanism 8. The moving cross bar 11 drives the two second clamping components 17 to pull the material to move, so that the moving material is straight until the material is pulled to the required length. After the pressing and cutting mechanism 8 presses and cuts the material, the second pulling device 4 can either pull the cut material to move a certain distance and then release the material, or directly release the material so that the cut material is stacked in the stacking bin 9.

[0033] In this embodiment, the second clamping assembly 17 includes a second clamping driver 18 mounted on the connecting arm 16 and two second clamping blocks 19 mounted on the two clamping ends of the second clamping driver 18. The second clamping driver 18 is used to drive the two second clamping blocks 19 toward or away from each other; specifically, the second clamping driver 18 can be a finger cylinder. In actual use, the second clamping driver 18 drives the two second clamping blocks 19 toward each other, causing them to clamp the sheet; the second clamping driver 18 drives the two second clamping blocks 19 away from each other, causing them to release the sheet.

[0034] Specifically, the first translation drive mechanism 10 and the second translation mechanism are located on the same side of the stacking bin 9; this structural design not only makes the machine compact and beautiful in appearance, but also facilitates the operator to remove the stacked sheets in the stacking bin 9 on one side of the machine.

[0035] Specifically, the stacking bin 9 includes a plurality of positioning rods detachably mounted on the machine 1, which enclose a stacking cavity. This structural design facilitates the assembly and disassembly of the positioning rods, and the number of positioning rods can be increased or decreased according to actual needs. It is also convenient to enclose a stacking cavity of the required number of positioning rods to meet the sheet material specifications.

[0036] In this embodiment, safety gratings 20 are installed on both the front and rear sides of the machine 1. The stacking bin 9, the first pulling device 3, and the second pulling device 4 are all located between the two sets of safety gratings 20. The installation of the safety gratings 20 improves safety performance. When the safety gratings 20 detect a foreign object (such as a human hand), they will send a command to the machine control system, causing the machine to stop and alarm.

[0037] In this embodiment, the roller conveying mechanism 7 includes a conveying seat 21 installed on the machine 1, an active roller 22 rotatably connected to the conveying seat 21, a lifting seat 23 connected to the conveying seat 21 for lifting and sliding and located above the active roller 22, a driven roller 24 rotatably connected to the lifting seat 23 and arranged parallel to the active roller 22, a lifting driver 25 installed on the top of the conveying seat 21 and used to drive the lifting seat 23 to rise and fall, and a rotating driver 26 installed on one side of the conveying seat 21 and used to drive the active roller 22 to rotate. The lifting driver 25 is used to drive the lifting seat 23 and the driven roller 24 to move closer to or away from the active roller 22, and the table surface of the supporting platform 6 is tangent to the top of the active roller 22; the lifting driver 25 can be a cylinder, and the rotating driver 26 includes a motor and a transmission component, and the transmission component can be a pulley component. In actual application, the sheet passes between the active roller 22 and the driven roller 24, and the rotating driver 26 drives the active roller 22 to rotate. The rotating active roller 22 cooperates with the driven roller 24 to drive the sheet to move, so as to realize the conveying of the sheet; the lifting driver 25 drives the lifting seat 23 and the driven roller 24 away from the active roller 22 to adjust the distance between the driven roller 24 and the active roller 22, which is convenient for the threading of the sheet. The distance between the driven roller 24 and the active roller 22 can also be adjusted according to the thickness of different sheets.

[0038] Specifically, the lifting seat 23 is equipped with a guide column 44, which slides through the top of the conveying seat 21; during the lifting and lowering process of the lifting seat 23, the guide column 44 is slidably connected to the conveying seat 21, thereby improving the lifting stability of the lifting seat 23.

[0039] Specifically, a spring 45 is provided on the outer sleeve of the guide post 44, and the two ends of the spring 45 elastically contact the conveying seat 21 and the lifting seat 23. When the driven roller 24 and the driving roller 22 cooperate to convey the web, the spring 45 not only acts as a buffer to prevent the web from being crushed, but also provides pre-pressure to the driven roller 24, which helps the driven roller 24 and the driving roller 22 to convey the web stably.

[0040] In this embodiment, the side of the support platform 6 away from the roller conveyor mechanism 7 is rotatably connected to a guide roller 27. The sheet moves along the support platform 6 after passing through the guide roller 27, which is beneficial to improving the movement stability of the sheet, and the setting of the guide roller 27 will not damage the sheet.

[0041] In this embodiment, the pressing and cutting mechanism 8 includes a pressing and cutting seat 28 installed on the machine 1, a knife seat 29 connected to the pressing and cutting seat 28 for lifting and sliding, an upper cutting knife 30 installed on the knife seat 29, a lower cutting knife 31 installed on the pressing and cutting seat 28 and located below the upper cutting knife 30, a cutting driver 32 installed on the top of the pressing and cutting seat 28 and used to drive the knife seat 29 to rise and fall, a lower pressing plate 33 installed on the pressing and cutting seat 28 and located on the feeding side of the lower cutting knife 31, an upper pressing plate 34 arranged on one side of the knife seat 29 and located above the lower pressing plate 33, and a support plate 35 installed on the pressing and cutting seat 28 and located on the discharge side of the lower cutting knife 31. The lower pressing plate 33 is tangent to the top of the active roller 22; specifically, the cutting driver 32 can adopt a cylinder.

[0042] In actual application, when the web moves, the upper cutting blade 30 and the lower cutting blade 31 are opened. When the web is pulled to the required length, the cutting driver 32 drives the blade holder 29, together with the upper cutting blade 30 and the upper pressing plate 34, to press downward synchronously, so that the upper pressing plate 34 presses the web onto the lower pressing plate 33, and the upper cutting blade 30 and the lower cutting blade 31 cooperate to cut the web. Then, the cutting driver 32 drives the blade holder 29, together with the upper cutting blade 30 and the upper pressing plate 34, to move upward and reset. The roller conveying mechanism 7 conveys the web and moves the web onto the support plate 35, with one end of the web extending outside the support plate 35. At this time, the first pulling device 3 clamps the web and then pulls the web. By pressing the web first and then cutting, or pressing and cutting simultaneously, the stability and quality of the web cutting process are improved.

[0043] In this embodiment, the upper pressing plate 34 is mounted on one side of the knife holder 29 via an elastic buffer assembly 36. When the upper pressing plate 34 presses the sheet against the lower pressing plate 33, the elastic buffer assembly 36 not only acts as a buffer to prevent damage to the sheet, but also provides a certain amount of preload to the upper pressing plate 34. Specifically, the elastic buffer assembly 36 includes a guide rod 37 mounted on the top surface of the upper pressing plate 34, a guide sleeve seat 38 mounted on one side of the knife holder 29, a limit plate 39 mounted on the top of the guide rod 37, and a compression spring 40 sleeved on the outside of the guide rod 37. The guide rod 37 slides through the guide sleeve seat 38. The two ends of the compression spring 40 elastically contact the top surface of the upper pressing plate 34 and the guide sleeve seat 38, respectively. The limit plate 39 is located above the guide sleeve seat 38 and is used to contact the guide sleeve seat 38.

[0044] Specifically, the pressing and cutting seat 28 is equipped with a protective plate, which is located above the support plate 35 and is arranged on the outside of the upper cutting knife 30. The setting of the protective plate shields the upper cutting knife 30 and the lower cutting knife 31, thereby improving the safety of use.

[0045] Specifically, the visual positioning mechanism 2 includes a support frame 43 mounted on the machine 1, and a visual camera 41 and an annular light source 42, respectively mounted on the support frame 43. The visual camera 41 is located above the annular light source 42 and is coaxially arranged with the annular light source 42. In actual application, the annular light source 42 provides supplemental light, and the visual camera 41 performs visual inspection of the marking on the sheet to identify the marking on the sheet.

[0046] Specifically, the unwinding mechanism 5 comprises a mounting base mounted on the machine platform 1, a pneumatic shaft rotatably connected to the mounting base, and a hysteresis tensioner mounted on the mounting base and drivably connected to the pneumatic shaft. In actual use, the web tray is inserted into the pneumatic shaft, which expands to grip the inner wall of the web tray's central hole. As the web is conveyed by the roller conveyor mechanism 7, the hysteresis tensioner applies tension to the web via the pneumatic shaft, ensuring a certain tension on the moving web and enabling it to move smoothly.

[0047] Specifically, the structure of the first translation drive mechanism 10 is the same as that of the second translation drive mechanism 15 , and both can adopt a screw module, which will not be described in detail here.

[0048] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
