The laser cutting head 8 is a carbon dioxide laser head or the like to have a sufficient cutting power.
The machine tool carrier 1 comprises a hill plate 13, and the laser cutting head 8 is located above the hill plate 13. The rapier plate 13 is sheet-shaped as a whole and comprises a rapier top 131, a rapier valley 132 and a rapier base 133; wherein the rapier dome 131 is used for supporting the nonmetallic workpiece 9, and the rapier base 133 is used for being fixed on the mounting surface of the machine tool carrier 1. The material of the sword mountain plate 13 may be selected according to the need, for example, metal, plexiglass, etc. It is easy to understand that the rapier plate 13 is at least two pieces to stably support the nonmetallic workpieces 9.
The laser cutting head 8 is activated and moved in a horizontal plane to cut the nonmetallic workpiece 9 placed on the rapier plate 13. The nonmetallic workpieces 9 are rectangular parallelepiped-shaped, such as rock plates, glass plates, and the like.
As shown in fig. 4, the machine tool carrier 1 further includes a plurality of X-axis stoppers 11 and a plurality of Y-axis stoppers 12, the plurality of X-axis stoppers 11 are disposed along a straight line perpendicular to the X-axis direction, the plurality of Y-axis stoppers 12 are disposed along a straight line perpendicular to the Y-axis direction, and the X-axis stoppers 11 and the Y-axis stoppers 12 each have a portion of the high Yu Jianshan plate 13. The nonmetallic workpiece 9 is placed on the Jianshan plate 13, and when two sides of the nonmetallic workpiece 9 respectively prop against the plurality of X-axis limiting pieces 11 and the plurality of Y-axis limiting pieces 12, the positions of the nonmetallic workpiece 9 are determined.
The carbon dioxide laser cutting device of the first embodiment further includes a driving assembly 2, the driving assembly 2 includes a driving support member 21 and a driving power member 22 connected to the driving support member 21, and the driving power member 22 makes an inclination angle 219 between a direction of linear motion of the driving support member 21 and an X-axis direction.

The working principle is that after the nonmetallic workpiece 9 is placed on the Jianshan plate 13, gaps are generally formed between two sides of the nonmetallic workpiece 9 and the X-axis limiting piece 11 and the Y-axis limiting piece 12. As shown in fig. 4, a direction DIR1 indicates a movement direction along the X-axis; direction two DIR2 represents the direction of motion along the Y axis; arrow-ARR 1 indicates the direction in which the driving power member 22 moves the driving abutment member 21 linearly; arrow two ARR2 indicates the tendency of the driving abutment 21 to abut the nonmetallic workpiece 9 to move along the X axis; arrow three ARR3 indicates the tendency of the driving abutment 21 to abut the nonmetallic workpiece 9 to move along the Y axis. The driving power piece 22 is started, so that the driving power piece 22 drives the driving abutting piece 21 to linearly move, the X-axis abutting body 211 abuts against the nonmetallic workpiece 9 to enable the nonmetallic workpiece 9 to move along the X axis, and the Y-axis abutting body 212 abuts against the nonmetallic workpiece 9 to enable the nonmetallic workpiece 9 to move along the Y axis until two sides of the nonmetallic workpiece 9 abut against the plurality of X-axis limiting pieces 11 and the plurality of Y-axis limiting pieces 12 respectively. At this time, four sides of the non-metal workpiece 9 are respectively abutted against the X-axis limiting member 11, the Y-axis limiting member 12, the X-axis abutting body 211 and the Y-axis abutting body 212, so that the non-metal workpiece 9 can be accurately fixed at the absolute starting point 91 (as shown in fig. 4, the point at the upper left corner of the non-metal workpiece 9 is the absolute starting point 91, and the X-axis coordinate value and the Y-axis coordinate value of the point are both zero), thereby enabling the laser cutting head 8 to set the cutting track based on the absolute starting point 91, accurately knowing the relative positions between the moving track of the laser cutting head 8 and the four sides of the non-metal workpiece 9, enabling the moving track of the laser cutting head 8 to be very close to the four sides of the non-metal workpiece 9, further reducing the width 92 of the leftover bits reserved at the four sides of the non-metal workpiece 9, and improving the utilization rate of the non-metal workpiece 9. As shown in fig. 18 and 19, the same nonmetallic workpiece 9 has a larger width 92 of the prior art scraps, and can only cut three circles; with the improvement of the invention, the scrap width 92 is smaller, and six circles can be cut.

For example, the output end of the driving power member 22 is rotatably connected with the driving supporting member 21 through a vertical hinge pin 229, the driving power member 22 extends to two sides to form an extension part 221, the supporting elastic members 23 are springs and two in number, and the two supporting elastic members 23 are respectively located at two sides of the hinge pin 229; each supporting elastic piece 23 is respectively connected with the driving supporting piece 21 and the extending part 221 to provide pulling force, so that the elastic force provided by the supporting elastic pieces 23 at two sides of the vertical straight line is the same in direction. The drive assembly 2 further comprises a drive carrier 29, the drive power member 22 being arranged on the drive carrier 29, the drive carrier 29 being provided with a drive guide 291 being a linear bearing, the sliding end of the drive guide 291 being fixedly connected with the extension 221. Referring to fig. 4, when an included angle exists between the diagonal line of the non-metal workpiece 9 and the direction (i.e., arrow-ARR 1) in which the driving power member 22 makes the driving abutment member 21 move linearly (e.g., the non-metal workpiece 9 is placed obliquely due to the size change of the non-metal workpiece 9), one of the X-axis abutment body 211 and the Y-axis abutment body 212 first abuts against one side of the non-metal workpiece 9, so that the driving abutment member 21 integrally rotates against the elastic force of the abutment elastic member 23 and adjusts the angle, and the non-metal workpiece 9 correspondingly adjusts the angle until the other side of the X-axis abutment body 211 and the Y-axis abutment body 212 abuts against the other side of the non-metal workpiece 9; the driving power member 22 continues to move the driving abutment member 21 linearly until the four sides of the nonmetallic workpiece 9 respectively abut against the X-axis limiting member 11, the Y-axis limiting member 12, the X-axis abutment body 211, and the Y-axis abutment body 212. In other words, the driving abutment 21 can automatically adjust the angle, ensuring that the nonmetallic workpiece 9 can be pushed smoothly.
As one specific embodiment, the X-axis limiting member 11, the Y-axis limiting member 12, the X-axis supporting body 211 and the Y-axis supporting body 212 are all hinged with the roller 7 with vertical axial lines, so that the roller 7 can horizontally rotate, when the non-metal workpiece 9 is pushed by the driving supporting member 21, the non-metal workpiece 9 can smoothly slide and cannot be clamped by the roller 7, and the non-metal workpiece 9 can be ensured to be accurately fixed at the absolute starting point 91.
In a second embodiment, please refer to fig. 5.
The carbon dioxide laser cutting device of the second embodiment is different from the first embodiment in that the machine tool carrier 1 further includes a frame beam 19, the drive assembly 2 further includes a quick drive member 299 fixed relative to the frame beam 19, the quick drive member 299 being a linear power device; the frame beam 19 is rotatably connected with a conveying roller 191; the rapier plate 13 is perpendicular to the conveying roller 191, the driving power member 22 is arranged on the driving carrier 29, the output end of the rapid driving member 299 is fixedly connected with the driving power member 22 (for example, fixedly connected through the driving carrier 29), and the linear power direction of the rapid driving member 299 is parallel to the linear power direction of the driving power member 22. The rapid drive 299 is extended and retracted to enable the drive abutment 21 and the drive power member 22 to retract the nonmetallic workpieces 9 moving on the conveyor rollers 191. In the process that the nonmetal workpiece 9 moves from the conveying roller 191 to the rapier plate 13 and then continues to move on the rapier plate 13, the friction force of the bottom end of the nonmetal workpiece 9 facing the rapier plate 13 is approximately along the length direction of the rapier plate 13, so that the rapier plate 13 (particularly the rapier top 131) can be ensured not to be bent or broken; thereby, the nonmetallic workpieces 9 can be conveniently conveyed onto the rapier plate 13 by the conveying rollers 191, and the thrust to the thrust transmitting piece 33 described later can be ensured by providing the secondary thrust.
In a third embodiment, please refer to fig. 6 to 16.
The carbon dioxide laser cutting device of the third embodiment is different from the first embodiment in that a cleaning assembly 3 is added. Since the carbon dioxide laser cutting device of the first embodiment can accurately fix the nonmetallic workpiece 9 at the absolute starting point 91, and replace the nonmetallic workpiece 9 with the cleaning component 3, the cleaning component 3 can also be accurately fixed at the absolute starting point 91, and further, the accurate positioning between the rapier plate 13 and the movable cleaning component 32 described later can be realized, and the automatic cleaning of the rapier plate 13 is realized.
The carbon dioxide laser cutting device of the third embodiment further comprises a cleaning assembly 3; the cleaning assembly 3 comprises a movable cleaning member 32 and a cleaning carrier 31 which can be placed on the rapier plate 13.
The cleaning carrier 31 is provided with a plurality of cleaning guide grooves 311 provided along the length direction of the rapier plate 13, and it should be noted that the cleaning guide grooves 311 provided along the length direction of one rapier plate 13 are a row of cleaning guide grooves 311.
The cleaning guide groove 311 comprises a approaching section 312, and the tail end of the approaching section 312 is close to the sword mountain plate 13 relative to the initial end; the movable cleaning member 32 is provided with a cleaning guide post 321 fitted into the cleaning guide groove 311; the driving abutment member 21 can directly or indirectly push the movable cleaning member 32 to move along the length direction of the rapier plate 13. For example, the driving abutting piece 21 directly contacts with the movable cleaning piece 32 and abuts against the movable cleaning piece 32, so that the driving abutting piece 21 directly pushes the movable cleaning piece 32 to move along the length direction of the rapier plate 13. For another example, the driving abutting piece 21 contacts with the movable cleaning piece 32 through other parts and abuts against the movable cleaning piece 32, so that the driving abutting piece 21 indirectly pushes the movable cleaning piece 32 to move along the length direction of the rapier plate 13. A suspension body 322 is arranged at the top end of the cleaning guide post 321; the diameter of the inscribed circle of the suspension body 322 is larger than the groove width of the cleaning guide groove 311 in a plan view, and the suspension body 322 is abutted against the cleaning carrier 31, so that the movable cleaning member 32 is suspended on the cleaning guide groove 311. Of course, the manner in which the movable cleaning member 32 is suspended from the cleaning guide groove 311 is not limited to the above.
The movable cleaning member 32 is located below the cleaning carrier 31; the movable cleaning member 32 is in side contact with the rapier plate 13 when the cleaning guide post 321 is positioned near the end of the segment 312.
The working principle is that, as shown in fig. 14, arrow four ARR4 indicates the moving path and direction of the cleaning guide post 321 along the cleaning guide slot 311 in the process that the movable cleaning member 32 is directly or indirectly pushed by the driving support member 21; the thick dashed circle represents the contour of the suspension 322 when the cleaning guide post 321 is located near the beginning of the segment 312.
Before use, the cleaning carrier 31 is placed on the sword mountain plate 13, so that two sides of the cleaning carrier 31 respectively prop against the X-axis limiting piece 11 and the Y-axis limiting piece 12, and the cleaning assembly 3 is accurately fixed at the absolute starting point 91. In the process, the cleaning guide post 321 is located near the initial end of the section 312, the movable cleaning member 32 is far away from the corresponding rapier plate 13, and the movable cleaning member 32 is not easily blocked by the rapier plate 13 when the cleaning carrier 31 is moved, so that the cleaning assembly 3 is accurately fixed at the absolute starting point 91.
When in use, the driving supporting piece 21 pushes the movable cleaning piece 32 to move along the length direction of the rapier plate 13, and the cleaning guide post 321 moves from the initial end of the approaching section 312 to the tail end of the cleaning guide post, so that the movable cleaning piece 32 approaches and contacts the side surface of the rapier plate 13, and automatic cleaning of the rapier plate 13 is realized. For example, when the longitudinal direction of the rapier plate 13 is set in the X-axis direction, the driving abutment 21 pushes the movable cleaning member 32 to move in the X-axis direction.
As one specific embodiment, the cleaning guide slot 311 further includes a parallel section 313 communicating with the end near the section 312, the parallel section 313 being parallel to the longitudinal direction of the rapier plate 13. The movable cleaning member 32 is driven by the driving supporting member 21 to move along the length direction of the rapier plate 13, and after the cleaning guide post 321 moves from the initial end close to the section 312 to the tail end of the cleaning guide post, the movable cleaning member 32 can contact the side surface of the rapier plate 13 and move a certain distance along the length direction parallel to the rapier plate 13 so as to clean the rapier plate 13, and the cleaning effect on the rapier plate 13 can be improved. The movable cleaning member 32 is provided on its side with a structure for enhancing frictional force such as a diamond-shaped protrusion on a sand paper or the like to enhance cleaning effect.
As one specific embodiment, the cleaning assembly 3 further includes a plurality of movable cleaning members 32, the cleaning assembly further includes a thrust transmitting member 33, the thrust transmitting member 33 is slidably connected with the cleaning carrier 31 along the length direction of the rapier plate 13, one end of each movable cleaning member 32 abuts against the thrust transmitting member 33, the thrust transmitting member 33 includes a pushed portion 331, and the pushed portion 331 has a portion overlapping with the cleaning carrier 31 in the height direction so as to limit the sliding of the pushing portion 331. The driving abutting piece 21 can abut against the pushed portion 331 and move the pushed portion 331, so that the pushing force transmitting piece 33 can indirectly push the plurality of movable cleaning pieces 32 to move; the movable cleaning members 32 do not need to be correspondingly provided with power devices, so that the structure is simplified and the cost is reduced.
As one of the specific embodiments, the cleaning assembly 3 further comprises a return elastic member 34, the return elastic member 34 being connected to the cleaning carrier 31, the movable cleaning member 32, respectively, so that the cleaning guide post 321 has a tendency to enter near the initial end of the segment 312. Each movable cleaning piece 32 can be reset automatically, so that the cleaning device is convenient, and meanwhile, the driving power piece 22 can drive the movable cleaning piece 32 to reciprocate, so that the multiple cleaning of the rapier plate 13 can be realized conveniently.
As one specific embodiment, the cleaning assembly 3 further includes a reset push plate 341 and a linear guide rail 36, the cleaning carrier 31 includes a guide rail mounting member 362 for fixing the linear guide rail 36, the linear guide rail 36 is sleeved with a linear sliding member 361, the reset push plate 341 is fixedly connected with the linear sliding member 361, for example, the reset push plate 341 is fixedly provided with a mounting ear 369, the mounting ear 369 is fixedly connected with the linear sliding member 361 through a screw, the other end of each movable cleaning member 32 abuts against the reset push plate 341, and two ends of the reset elastic member 34 abut against the guide rail mounting member 362 and the reset push plate 341 (as shown in fig. 11 and 16, abut against the mounting ear 369 of the reset push plate 341) respectively to provide a repulsive force. Typically, the return elastic member 34 is a spring and is sleeved on the linear guide rail 36. The repulsive force provided by the return elastic member 34 causes the return push plate 341 to abut against the other end of each movable cleaning member 32, thereby causing each cleaning guide post 321 to have a tendency to enter near the initial end of the segment 312. The above structure arrangement can synchronously reset each movable cleaning piece 32, and the reset elastic piece 34 does not need to be arranged corresponding to each movable cleaning piece 32, which is beneficial to simplifying the structure and reducing the cost.
As one of the specific embodiments, the thrust transmission member 33 is fixedly connected with the other linear sliding member 361, for example, the thrust transmission member 33 is fixedly provided with a mounting lug 369, and the mounting lug 369 is fixedly connected with the linear sliding member 361 by a screw; the cleaning assembly 3 further includes a pre-pressing elastic member 35, where two ends of the pre-pressing elastic member 35 respectively abut against the thrust transmitting member 33 and the reset pushing plate 341 (for example, respectively abut against the mounting ear 369 of the thrust transmitting member 33 and the mounting ear 369 of the reset pushing plate 341) to provide a repulsive force. When the pushing member 21 is driven to push the pushing member 33, the compression amount of the pushing member 35 increases to provide a repulsive force, and a trend of moving the restoring push plate 341 away from the other end of the movable cleaning member 32 is generated, which is offset by a trend of moving the movable cleaning member 32 generated by the restoring elastic member 34 (i.e., a trend of moving the cleaning guide post 321 into the cleaning guide post 321 near the initial end of the segment 312), so that the pushing member 33 can be ensured to be pushed by the driving member 21 smoothly.
As one specific embodiment, the approaching sections 312 of the two rows of cleaning guide grooves 311 closest to the same rapier plate 13 are opposite in orientation, so as to clean both side surfaces of one rapier plate 13 by the corresponding two movable cleaning members 32. For example, the two rows of cleaning guides 311 closest to one of the rapier plates 13 are mirror images of each other, so that the adjacent sections 312 are opposite in orientation, and each movable cleaning member 32 can be identical, which is advantageous for cost reduction.
In a fourth embodiment, please refer to fig. 17.
The carbon dioxide laser cutting device of the fourth embodiment is different from the third embodiment in a thrust transmitting piece 33.
The pushed portion 331 includes an X-axis pushed frame 332 and a Y-axis pushed frame 333 that are perpendicular to each other. When the movable cleaning member 32 is pushed by the pushing member 21 pushing the pushed portion 331, the X-axis pushing body 211 and the Y-axis pushing body 212 are respectively pushed against the X-axis pushed frame 332 and the Y-axis pushed frame 333, and the X-axis pushing body 211 or the Y-axis pushing body 212 is prevented from being caught in the gap between the pushing force transmitting member 33 and the cleaning carrier 31, so that the reliability is high.
