Description
Technical Field
[0001] The invention relates to the technical field of laser cutting equipment, in particular to a 3D printer optical film laser cutting and forming equipment. Background Art
[0002] 3D printer optical film is a special type of light-transmitting film material, specially designed for use in the optical system of 3D printers. This optical film usually has high transparency and uniform optical properties, and can maintain stable optical properties during the printing process. It is usually classified as a special flexible material so that it can withstand UV exposure and other process requirements during the printing process.
[0003] After laser cutting of the 3D printer translucent film, the automatic separation of waste and finished products is a relatively complicated process. Generally, the separation of waste and finished products may require human intervention, such as manual peeling or the use of tools to assist in removal.
[0004] A Chinese patent with announcement number CN117943713B discloses an optical film laser cutting device, including a laser slitting machine. The loading part is used to load and transport the optical film as a whole. The laser cutting point is located at the intersection of the water surface and the film material protruding from the water surface. It can effectively reduce the heat-affected zone and the fiber pull-out length. At the same time, it effectively avoids the problem that water absorbs part of the laser energy during underwater cutting, resulting in small cutting slits, large serrations, and uneven cutting slits.
[0005] A Chinese patent with announcement number CN116174940B discloses a protective film laser cutting device. In the present invention, the protective film passes through the transmission component and the cutting component in sequence under the conveying action of the transmission component and is recovered by the recovery component. When the protective film passes through the cutting component, the laser cutting head can cut the protective film and finally cut it into shape. The protective film can be automatically conveyed through the transmission component, so that the laser cutting head can cut continuously.
[0006] The above and similar prior arts, when performing 3D printer optical film laser cutting, need to first transport the 3D printer optical film to the bottom of the laser generator, stop transportation and perform laser cutting, the time to cut the finished product is the 3D printer optical film delivery time plus the cutting time, the cutting process is intermittent and not coherent, the processing efficiency is low, and it is not conducive to large-scale processing, and the 3D printer optical film is still stuck in the cutting hole after cutting, and human intervention is required to separate it, which further reduces the processing efficiency and has a low degree of automation.

DETAILED DESCRIPTION
[0033] In order to make the technical means, technical features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0034] Example: Figure 1-Figure 9 As shown, a 3D printer optical film laser cutting and forming device described in the present invention includes a workbench 1, a cutting pool 2 is fixedly installed on the top of the workbench 1, a leakage pool 3 is fixedly installed on one side of the cutting pool 2 through a partition, a film 22 is arranged on the top of the cutting pool 2 and the leakage pool 3, a transmission shaft 4 is installed through a bearing on one side of the cutting pool 2, a plurality of pillars 5 are respectively located on both sides of the cutting pool 2, two pillars 5 on one side of the cutting pool 2 close to the transmission shaft 4 are fixedly installed with a driving motor 6 through a cross plate, and the output end of the driving motor 6 is fixedly connected to the transmission shaft 4, a storage roller 16 is rotatably installed on the top of the leakage pool 3 through a fixed plate 15 and a bearing, and a rotatable rotating tube 17 is mounted on the outer side of the storage roller 16, a filter screen 20 is fixedly installed on the inner side of the leakage pool 3, a water pump 21 is fixedly installed on the inner side of the leakage pool 3, and the output end of the water pump 21 passes through the partition and enters the inner side of the cutting pool 2.
[0035] Specifically, the workbench 1 can provide stable support for the cutting pool 2 and the water leakage pool 3, the cutting pool 2 can provide storage space for the cutting liquid, and can provide rotational support for one end of the transmission shaft 4, the pillar 5 can provide stable support for the driving motor 6 through the cross plate, the driving motor 6 can provide rotational driving force for the transmission shaft 4, the water leakage pool 3 can provide rotational support for the storage roller 16 through the fixed plate 15, the storage roller 16 and the rotating tube 17 are clearance-matched, and the two can rotate relative to each other, the storage roller 16 provides a rotational driving force for the rotating tube 17, and when the storage roller 16 is started, it will drive the rotating tube 17 to rotate, and after the film 22 between the feeding roller 111 and the rotating tube 17 is tightened, the tension of the film 22 increases and pulls the rotating tube 17 in the reverse direction, so that the rotating tube 17 and the storage roller 16 produce relative rotation, and the static friction between the storage roller 16 and the rotating tube 17 will be converted into sliding friction, the rotation speed of the rotating tube 17 is reduced, and the feeding roller 111 and the squeezing roller 113 will not produce relative rotation with the film 22 Sliding, that is, the conveying speed of the film 22 remains unchanged. Due to the reduction in the rotation speed of the rotating tube 17, the film 22 between the feeding roller 111 and the rotating tube 17 will become loose. At this time, the sliding friction between the storage roller 16 and the rotating tube 17 will increase again and approach the size of the static friction, driving the rotating tube 17 to rotate faster, and re-tighten the loose film 22, and then repeat the above process. During this process, the tension exerted on the film 22 is not enough to break the film 22 itself; the leakage pool 3 can provide storage space for cutting, and the leakage pool 3 can provide a stable support for the filter screen 20. The filter screen 20 is in an inclined state. The filter screen 20 can provide a stable support for the finished film 22 after cutting. When the film 22 in the cutting pool 2 moves to the leakage pool 3, a large amount of cutting fluid is attached to the surface of the finished film 22. The finished film 22 falls on the filter screen 20 and stands still, which can make the cutting fluid on the surface of the film 22 flow along the inclined direction of the filter screen 20, reducing the adhesion of the cutting fluid on the surface of the film 22.
[0036] In this embodiment, a cutting mechanism 7 is fixedly installed on the top of the workbench 1 through a plurality of pillars 5. The cutting mechanism 7 includes an N-shaped frame 71. The cutting mechanism 7 is configured to intermittently perform cutting in the X-axis direction through two laser generators 72 arranged at the bottom of the N-shaped frame 71, and a conveyor belt 75 conveys the other two laser generators 72 to intermittently perform cutting in the Y-axis direction; the N-shaped frame 71 is fixedly installed on the top of the pillar 5, and a rotating shaft 73 is installed inside the N-shaped frame 71 through a bearing, and the rotating shaft 73 is perpendicular to the beam in the middle of the N-shaped frame 71. One end of the rotating shaft 73 is embedded in one side of the N-shaped frame 71 through a bearing, and a conveying wheel 74 is fixedly installed on the other end of the rotating shaft 73. Another conveying wheel 74 is rotatably installed on one side of the N-shaped frame 71 through a bearing. A conveyor belt 75 is mounted on the outside of the two conveying wheels 74. Two laser generators 72 are fixedly installed at the bottom of a beam in the Y-axis direction of the N-shaped frame 71, and the other two laser generators 72 are respectively fixedly installed on the outside of the conveyor belt 75. The direction along which the film 22 is transported is the X-axis, and the direction perpendicular to the film 22 is the Y-axis.
[0037] Specifically, the N-shaped frame 71 can provide a stable support for the laser generator 72, and the laser generator 72 can intermittently emit a laser for cutting. The N-shaped frame 71 can provide a rotation support for the rotating shaft 73, and the rotating shaft 73 can provide a rotational power for the conveying wheel 74. The conveying wheel 74 can provide transportation for the other two laser generators 72 through the conveyor belt 1 75. The two laser generators 72 on the surface of the conveyor belt 1 75 will only emit a laser for cutting when facing the bottom. Since the rotating shaft 73 and the feeding roller 111 are both provided with a rotational driving force by the transmission shaft 4, the angular velocity of the rotating shaft 73 and the feeding roller 111 is the same as that of the transmission shaft 4. The diameter of the conveying wheel 74 is twice the diameter of the feeding roller 111, and the transport speed of the conveyor belt 75 is twice the transport speed of the film 22. Because the parallel angle in the N-shaped frame 71 is 30°, the transport speed of the conveyor belt 75 in the X-axis direction is the same as the transport speed of the film 22, which means that during the transportation of the film 22, the laser generator 72 on the surface of the conveyor belt 75 does not cut the film 22 in the X-axis direction, but only cuts in the Y-axis direction. The two laser generators 72 at the bottom of the N-shaped frame 71 only cut in the X-axis direction. The cooperation of the two can cut a complete square finished film 22.
[0038] In this embodiment, a detachable input roller 10 is installed on the top of the cutting pool 2 through two support plates 9, and a feeding assembly 11 is arranged inside the cutting pool 2. The feeding assembly 11 includes a feeding roller 111, and both ends of the feeding roller 111 are respectively installed inside the cutting pool 2 through bearings, and the feeding roller 111 is connected to the transmission shaft 4 through a belt transmission group 112. An extrusion roller 113 is rotatably installed inside the cutting pool 2 through a bearing, and the extrusion roller 113 is located at the bottom of the feeding roller 111, and the extrusion roller 113 and the feeding roller 111 are connected through a gear transmission group 1 114.
[0039] Specifically, the detachable input roller 10 can facilitate the replacement of the rolled film 22, the belt drive group 112 includes two pulleys and a belt, which are used for the transmission between the drive shaft 4 and the feed roller 111, the cutting pool 2 can provide rotation support for the feed roller 111 and the squeeze roller 113, the gear drive group 114 includes two mutually meshing gears, which are used for the transmission between the feed roller 111 and the squeeze roller 113, so that the feed roller 111 and the squeeze roller 113 rotate in opposite directions under the transmission action of the gear drive group 114, the feed roller 111 and the squeeze roller 113 squeeze the film 22, and use friction to feed the film 22.
[0040] In this embodiment, a dividing roller 12 is rotatably installed inside the cutting pool 2 through a bearing, and a pushing assembly 13 is arranged inside the dividing roller 12. The pushing assembly 13 is assembled to separate the finished film 22 from the waste after cutting; the pushing assembly 13 includes two groups of inclined grooves 131, each group of inclined grooves 131 has a plurality of inclined grooves, and the two groups of inclined grooves 131 are respectively arranged in a circular array on the outside of the dividing roller 12, and a limiting groove 132 is arranged at the center position of the bottom side of the inclined groove 131. The limiting groove 132 is cylindrical, and a spring 133 is placed on the inside of the limiting groove 132. A limiting rod 134 is fixedly installed at one end of the spring 133, and an extrusion block 135 is fixedly installed at the end of the limiting rod 134 away from the spring 133, and the extrusion block 135 is located on the inside of the inclined groove 131.
[0041] Specifically, the feed roller 12 can provide an opening space for the inclined groove 131, and the inclined groove 131 can provide a movable space for the extrusion block 135. The inclined groove 131 is triangular in shape and is used to prevent the extrusion block 135 from moving out of the inclined groove 131. The bottom of the inclined groove 131 can provide an opening space for the limit groove 132, and the limit groove 132 can provide a guide for the limit rod 134. The limit groove 132 can provide a placement space for the spring 133. The feed roller 12 cooperates with the feed roller 111 to keep the film 22 in a horizontal state, which is convenient for cutting. In the cutting liquid, the film 22 is always in the cutting liquid during the cutting process, which can reduce the generation of cutting smoke. When the film 22 passes through the bottom of the dividing roller 12, the film 22 forms a certain wrap angle with the dividing roller 12 under the action of the rotating tube 17. When the waste film 22 contacts the extrusion block 135, the film 22 pushes the extrusion block 135 into the inner side of the inclined groove 131 under the action of the tension force. When the finished film 22 contacts the extrusion block 135, the extrusion block 135 gives the finished film 22 a downward thrust under the action of the spring 133, so that the finished film 22 is separated from the waste film 22.
[0042] In this embodiment, a dividing component 19 is provided on the inner side of the cutting pool 2; the dividing component 19 is equipped to transport the finished film 22 after cutting to the inner side of the leakage pool 3, and the dividing component 19 includes a splitting plate 191, and the splitting plate 191 is fixedly installed on the inner side of the cutting pool 2, and a lower pressure roller 192 is rotatably installed on one side of the splitting plate 191, and a conveying roller 193 is rotatably installed inside the cutting pool 2 through a bearing, and the conveying roller 193 is located at the bottom of the dividing roller 12, and the conveying roller 193 is connected to the dividing roller 12 through a gear transmission group 2 194, and a conveying roller 2 195 is rotatably installed on the top of the partition, and the conveying roller 193 and the conveying roller 2 195 are connected through a conveyor belt 2 196.
[0043] Specifically, the cutting pool 2 can provide stable support for the splitting plate 191, the splitting plate 191 can provide rotational support for the lower pressure roller 192, the cutting pool 2 can provide rotational support for the conveying roller 193, and the partition can provide stable support for the conveying roller 2 195. When the finished film 22 is separated from the waste film 22, a part of the finished film 22 is still on the inside of the cutting hole, so that the finished film 22 will not fall off immediately. The separated part of the finished film 22 continues to move along the X-axis direction to between the splitting plate 191 and the conveying belt 2 196. Through the extrusion of the lower pressure roller 192 and the conveying belt 2 196 and the rotation of the conveying belt 2 196, the finished film 22 moves to the leakage pool 3 under the conveying action of the conveying belt 2 196. The gear transmission group 2 194 includes two meshing gears, so that the rotation direction of the conveying roller 2 195 is opposite to the rotation direction of the dividing roller 12.
[0044] In this embodiment, the transmission shaft 4 and the rotating shaft 73 are connected through a belt transmission group 1 8, the transmission shaft 4 and the dividing roller 12 are connected through a belt transmission group 3 14, and the transmission shaft 4 and the receiving roller 16 are connected through a belt transmission group 4 18. The film 22 is rolled and wrapped around the outside of the input roller 10, and the film 22 passes between the feeding roller 111 and the squeezing roller 113, contacts the bottom of the dividing roller 12, passes between the splitting plate 191 and the conveyor belt 2 196, and one end of the film 22 is connected to the outside of the rotating tube 17.
[0045] Specifically, the belt drive group 1 8, the belt drive group 3 14 and the belt drive group 4 18 are all composed of two pulleys and one belt. The belt drive group 1 8 is used for transmission between the drive shaft 4 and the rotating shaft 73, the belt drive group 3 14 is used for transmission between the drive shaft 4 and the dividing roller 12, and the belt drive group 4 18 is used for transmission between the drive shaft 4 and the collecting roller 16.
[0046] Working principle: the staff first injects cutting fluid into the cutting pool 2 so that the cutting fluid just submerges the bottom of the feed roller 111, starts the drive motor 6, and drives the drive shaft 4 to rotate in the opposite direction. The drive shaft 4 drives the feed roller 111 to rotate through the belt transmission group 2 112. The feed roller 111 drives the squeeze roller 113 to rotate by the meshing action of the gear transmission group 1 114. The feed roller 111 rotates in the opposite direction to the squeeze roller 113, and the friction force is used to drive the film 22 to be transported. At the same time, the drive shaft 4 drives the storage roller 16 to rotate through the belt transmission group 4 18, so that the storage roller 16 uses the change of friction force to give the rotating tube 17 a variable rotation driving force, so that the rotating tube 17 always maintains a tendency to rotate, so that the rotating tube 17 and the feed roller 111 are used to intermittently tighten the film 22, thereby preventing the film 22 from being damaged due to excessive tension;
[0047] The two laser generators 72 at the bottom of the N-shaped frame 71 intermittently emit laser to cut the film 22, leaving two transverse cutting holes in the X-axis direction of the film 22 at intervals. When the end of a cutting hole is close to the laser generator 72 at the bottom of the conveyor belt 75, the laser generator 72 emits laser cutting, and at the same time, the transmission shaft 4 drives the rotating shaft 73 to rotate through the belt transmission group 8, so that the rotating shaft 73 drives the conveying wheel 74 to rotate, and the conveying wheel 74 drives the bottom laser generator 72 to move through the conveyor belt 75. Since the two parallel angles of the N-shaped frame 71 are 30°, and the diameter of the conveying wheel 74 is twice the diameter of the feeding roller 111, when the rotation angle is When the speeds are the same, the distance that the conveyor belt 75 drives the laser generator 72 to move is twice the distance that the film 22 moves in the X direction. According to the Pythagorean theorem of a 30° right triangle, the long hypotenuse is twice the length of the short right-angled side. If the moving speed of the laser generator 72 on the surface of the conveyor belt 75 in the X-axis direction is the same as the transportation speed of the film 22, and the two are relatively stationary, the laser generator 72 on the surface of the conveyor belt 75 will only leave two cutting holes in the Y-axis direction of the film 22. The two X-cutting holes and the two Y-axis cutting holes cut out a square finished product, so that the finished product can be cut while the film 22 is being transported all the time.
[0048] When the cut film 22 moves to the bottom of the dividing roller 12, the spring 133 pushes the extrusion block 135 downward through the limit rod 134, so that the extrusion block 135 gives downward pressure to the cut finished product, so that the finished product and the waste after the film 22 is cut are separated from each other. After the waste leaves the dividing roller 12, it moves obliquely upward under the storage action of the rotating tube 17, and the finished product continues to move in the X-axis direction under the action of its own material properties, so that the finished product enters the position between the splitting plate 191 and the conveyor belt 2 196, and the transmission shaft 4 drives the dividing roller 12 to rotate in the opposite direction through the belt transmission group 3 14, and the dividing roller 12 uses the gear transmission group 2 194 to drive the conveyor roller 1 193 to rotate forward, and the conveyor roller 193 drives the conveyor belt 2 196 to rotate forward, so that the conveyor belt 2 196 and the lower pressure roller 192 are used to extrude and convey the finished product, and the finished product is conveyed to the top of the filter screen 20 for standing, thereby reducing the cutting fluid attached to the surface of the finished product.
