Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and specifically relates to a laser cutting device for cabinet panels. Background Art

[0002] The cabinet panels of electrical cabinets are used to protect the electrical components inside the cabinets from the influence of external environmental factors, such as dust, moisture, foreign objects, etc., prevent faults such as component short circuits and electric leakage, extend the service life of electrical components, and the cabinet panels of electrical cabinets can also provide good insulation performance, isolate the live parts inside the cabinets from the outside, prevent operators from getting an electric shock, ensure personal safety, and also avoid short circuits between conductors with different potentials.

[0003] The existing patent with the publication number CN117340445B in China discloses an intelligent laser cutting device for switch cabinet panels to solve the problems of low raw material feeding efficiency and difficult waste removal, but the above patent also has the following defects:

[0004] First, the raw material cabinet panels are stacked vertically in the frame body, and the raw material cabinet panels are fed from bottom to top. The above patent uses a dialing plate member to drive the lower raw material cabinet panel to drive outwards, and uses the first roller on the dialing plate member to jack up the upper raw material panel. However, the first roller is small in size, and the first roller can only jack up one end of the raw material panel. At this time, the lowermost raw material cabinet panel will still rub against the upper raw material cabinet panel. Moreover, the feeding device of the above patent can only be applied to small-sized plates. For medium and large-sized plates, due to the heavy weight of the plates, it is impossible to drive the feeding by the dialing plate member;

[0005] Second, after the plate is laser cut, the formed material will be transported away by the blanking mechanism, and the cut waste will fall into the blanking channel through the blanking through groove, and finally the separation of the waste is realized. However, the blanking through groove in the above patent is a fixed structure. Therefore, during cutting, the laser cutting head can only cut out corresponding cuts according to the structure of the blanking through groove. If the cut is changed, the cut waste cannot smoothly fall into the blanking channel through the blanking through groove. Therefore, the waste separation device of the above patent has great limitations.

[0006] Then, in view of the above problems, it is necessary to provide a laser cutting device for cabinet panels to solve. Summary of the Invention

[0007] Based on this, it is necessary to provide a laser cutting device for cabinet panels aiming at the problems in the prior art.

[0008] To solve the problems of the existing technology, the technical solution adopted by the present invention is as follows: A laser cutting device for cabinet boards, comprising a linear transport table and a laser cutting assembly.

One end of the strip-shaped sliding guide frame is rotatably connected to one set of transverse movement arms, and the other end of the strip-shaped sliding guide frame is inserted and connected to the other set of transverse movement arms. A flipping member for driving the two sets of strip-shaped sliding guide frames to flip synchronously is arranged above the carrier table. The laser cutting mechanism includes a laser cutting head and a three-axis displacement mechanism. The three-axis displacement mechanism is arranged above the carrier table, and the laser cutting head is arranged at the end of the three-axis displacement mechanism.

[0009] Further, the carrier table includes a material box and a toothed bracket. The material box is fixed at the end of the linear transport table, and the top of the material box is an open structure. The toothed bracket is fixed inside the opening at the top of the material box. The toothed bracket includes a plurality of toothed strips spaced apart in the horizontal direction. Each toothed strip is vertical, and a plurality of uniformly distributed anti-slip teeth are formed at the top of each toothed strip. The blanking cavity is opened inside the material box, and the waste outlet is opened on the outer wall of one side of the material box. The toothed bracket is the hollow structure at the top of the carrier table. The cabinet board limiting member includes four sets of end angle limiting plates distributed in a matrix. Each set of end angle limiting plates is composed of two vertical plates perpendicular to each other. Vertical limiting plates are formed on the adjacent two sets of end angle limiting plates far from the linear transport table.

[0010] Further, two symmetrically arranged sliding seats are fixedly arranged on both sides of the material box. Each set of lifting arms is vertically slidably connected to the corresponding sliding seat. A horizontal connecting rod is arranged between the two sets of lifting arms in each set of lifting brackets. The two ends of the connecting rod are fixedly connected to the corresponding two sets of lifting arms respectively. A plurality of cylinders are arranged below each connecting rod at equal intervals in the horizontal direction. The output end of each cylinder faces upward and is fixedly connected to the corresponding connecting rod.

[0011] Further, each set of transverse movement arms includes two transverse movement plates symmetrically arranged on both sides of the corresponding lifting arm. Each transverse movement plate is slidably connected to the corresponding lifting arm. A rectangular block is fixedly arranged between two adjacent transverse movement plates. A vertically downward convex block is formed at the bottom of the rectangular block. A horizontal limiting rod is fixedly arranged on the convex block. The limiting rod passes through the corresponding lifting arm, and a limiting nut is screwed on the end of the limiting rod passing through the lifting arm.

[0012] Further, a horizontal spring is sleeved on each limiting rod, and two ends of the spring respectively abut against the bump and the lifting arm. A triangular block is formed on each transverse movement plate, and a vertical strip fixedly connected to the outer wall of the material box is arranged below each triangular block. A first inclined surface is formed on each triangular block, and a second inclined surface which is inclined-wedge matched with the first inclined surface is formed on the top of each vertical strip.

[0013] Further, each group of strip-shaped guide sliding frames includes a U-shaped strip plate and a plurality of guide pulleys. The U-shaped strip plate is horizontally arranged, and the plurality of guide pulleys are equidistantly installed in the U-shaped strip plate along the horizontal direction. A side baffle vertically upward is formed on one side of the U-shaped strip plate.

[0014] Further, an insertion block is fixedly arranged at one end of each U-shaped strip plate facing the linear transport table, a rotating shaft is fixedly arranged at the other end of each U-shaped strip plate, a slot is formed on each rectangular block close to the linear transport table, each insertion block is inserted downward into the corresponding slot, and each rotating shaft is rotatably connected to the rectangular block far from the linear transport table.

[0015] Further, the turnover member includes two groups of abutting members in a symmetrical state. Each group of abutting members includes a first fixing pin and a second fixing pin. The first fixing pin is horizontally fixed to one end of the corresponding U-shaped strip plate and is close to the rotating shaft. The second fixing pin is horizontally fixed to the corresponding end angle limiting plate. The second fixing pin is located above the first fixing pin, and the first fixing pin and the second fixing pin are perpendicular to each other.

[0016] Further, the three-axis displacement mechanism includes a moving frame, a moving seat and a lifting seat. Support frames are fixedly arranged on both sides of the material box. Two ends of the moving frame are respectively slidably connected to the two support frames. The moving seat is slidably connected to the moving frame, and the lifting seat is slidably connected to the moving seat. The moving frame and the moving seat both slide along the horizontal direction, and the sliding directions of the moving frame and the moving seat are perpendicular to each other. The laser cutting head is fixedly connected to the lifting seat.

[0017] The beneficial effects of the present invention compared with the prior art are as follows:

[0018] Firstly, when loading the carrier table of the present device, the cabinet board driven out from the linear transport table is placed on the carrier table through the placing mechanism. In this process, the cabinet board will not directly collide with the carrier table, thereby preventing the cabinet board from being damaged. And through the cooperation of the linear transport table and the placing mechanism, medium and large cabinet boards can be loaded.

[0019] Secondly, a toothed bracket is arranged in the carrier table of the present device, and the toothed bracket is used for supporting the cabinet board. After laser cutting, the cut waste will fall downward onto the blanking inclined plate through the interval between adjacent toothed strips. Since the interval between adjacent toothed strips is large, the carrier table of the present device can allow waste of different shapes and sizes to fall by itself.

[0020] Thirdly, when the cabinet board is placed on the loading platform, the two sets of strip-shaped guide slides will displace away from each other during the descending process. In this way, after the cabinet board is placed on the toothed bracket, the two sets of strip-shaped guide slides will separate from the cabinet board, ultimately preventing the strip-shaped guide slides from interfering with the laser cutting head's cutting of the cabinet board.

Detailed implementation mode

[0035] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and specific implementation modes.

[0036] Refer to Figures 1 to 13 A cabinet panel laser cutting device as shown, including a linear transport table 1 and a laser cutting assembly. The linear transport table 1 is horizontally arranged, and the laser cutting assembly is arranged at the end of the linear transport table 1. The laser cutting assembly includes a carrier table 2, a placement mechanism 3 and a laser cutting mechanism 4. A blanking cavity 5 is arranged in the carrier table 2 (combined with Figure 1 and Figure 7 ), the top of the carrier table 2 is a hollow structure communicated with the blanking cavity 5, a cabinet panel limiting member is arranged on the top of the carrier table 2, a waste outlet 6 is arranged on one side of the carrier table 2, a blanking inclined plate 7 for guiding waste into the waste outlet 6 is arranged in the blanking cavity 5. The placement mechanism 3 includes two groups of lifting supports symmetrically arranged on both sides of the carrier table 2 respectively. Each group of lifting supports includes a transverse moving frame and two groups of lifting arms 8. The two groups of lifting arms 8 are equidistantly distributed in the horizontal direction. The transverse moving frame includes a strip-shaped guide slide 9 and two groups of transverse moving arms 10 (combined with Figure 4 and Figure 12 ), each group of transverse moving arms 10 is connected to the corresponding lifting arm 8, the strip-shaped guide slide 9 is horizontally arranged on the two groups of transverse moving arms 10, one end of the strip-shaped guide slide 9 is rotatably connected to one group of transverse moving arms 10, the other end of the strip-shaped guide slide 9 is inserted and connected to the other group of transverse moving arms 10, and a flipping member for driving the two groups of strip-shaped guide slides 9 to flip synchronously is arranged above the carrier table 2. The laser cutting mechanism 4 includes a laser cutting head 11 and a three-axis displacement mechanism. The three-axis displacement mechanism is arranged above the carrier table 2, and the laser cutting head 11 is arranged at the end of the three-axis displacement mechanism.

[0037] The cabinet board is horizontally placed on the linear conveyor 1, and the cabinet board is sent to the laser cutting assembly through the linear conveyor 1. The linear conveyor 1 is a prior art. Among them, a number of equally spaced retaining bars 42 are formed on the conveyor belt inside the linear conveyor 1, and the cabinet board is driven to move forward through the retaining bars 42. When the cabinet board moves to the end of the linear conveyor 1, the two lifting arms 8 on each set of lifting brackets will synchronously drive the corresponding transverse moving frame to rise. During this process, the two strip-shaped guiding and sliding frames 9 will synchronously rise to correspond to the cabinet board at the end of the linear conveyor 1. Thereafter, the cabinet board at the end of the linear conveyor 1 will slide onto the two strip-shaped guiding and sliding frames 9. At this time, the two ends of the cabinet board are lifted by the two strip-shaped guiding and sliding frames 9. When the cabinet board is lifted by the two strip-shaped guiding and sliding frames 9, the two lifting arms 8 on each set of lifting brackets will synchronously drive the corresponding transverse moving frame to descend. Then, the cabinet board lifted by the two strip-shaped guiding and sliding frames 9 will drop onto the carrier 2. During this process, the cabinet board is limited by the cabinet board limiting member at the top of the carrier 2. When the cabinet board is placed on the top of the carrier 2, the two transverse moving arms 10 in each set of transverse moving frames will synchronously drive the corresponding strip-shaped guiding and sliding frames 9 to move outward. At this time, the two strip-shaped guiding and sliding frames 9 move away from each other, so that the end parts of each strip-shaped guiding and sliding frame 9 corresponding to the cabinet board are separated, preventing the strip-shaped guiding and sliding frames 9 from affecting the subsequent cutting of the cabinet board by the laser cutting head 11. When the cabinet board is placed on the top of the carrier 2, the cabinet board is cut by the laser cutting head 11. Among them, the laser cutting head 11 is translated through a three-axis displacement mechanism, so that the laser cutting head 11 can cut different parts of the cabinet board according to the current processing technology. During the cutting process, the cut waste will fall downward through the hollow structure at the top of the carrier 2 onto the blanking inclined plate 7, and finally the waste will slide to the waste outlet 6 through the blanking inclined plate 7. When the cabinet board is cut, the two transverse moving arms 10 on each set of transverse moving frames will synchronously drive the strip-shaped guiding and sliding frames 9 to move towards the end of the cabinet board. At this time, the two strip-shaped guiding and sliding frames 9 move towards each other. When the strip-shaped guiding and sliding frames 9 move to the end of the cabinet board, the lifting arm 8 will drive the corresponding strip-shaped guiding and sliding frames 9 to rise again. Finally, the two ends of the cabinet board will be lifted by the two strip-shaped guiding and sliding frames 9 again. When the cabinet board rises close to the flipping member, the flipping member will drive the two strip-shaped guiding and sliding frames 9 to flip synchronously. During this process, the end of the strip-shaped guiding and sliding frame 9 inserted into the transverse moving arm 10 will tilt upward, so that the two strip-shaped guiding and sliding frames 9 will change from a horizontal state to an inclined state. Finally, the cabinet board lifted by the strip-shaped guiding and sliding frames 9 will slide down by itself. During the actual use process, a collection box (not shown in the figure) for collecting finished cabinet boards can be installed beside the carrier 2. When the cabinet board slides out of the strip-shaped guiding and sliding frames 9, the cabinet board will fall into the collection box for collection. When the cabinet board in front is being cut, the cabinet board on the linear conveyor 1 stops conveying. When the cabinet board falls into the collection box after being cut, the two strip-shaped guiding and sliding frames 9 will move again to correspond to the cabinet board on the linear conveyor 1. Thereafter, the cabinet board on the linear conveyor 1 will slide onto the two strip-shaped guiding and sliding frames 9 again, and finally the cutting of a batch of cabinet boards is realized.

[0038] In order to show the specific structures of the carrier table 2 and the cabinet panel limiting members, the following features are provided:

[0039] The carrier table 2 includes a material box 12 and a toothed bracket. The material box 12 is fixed at the end of the linear transport table 1. The top of the material box 12 is of an open structure. The toothed bracket is fixed in the opening at the top of the material box 12. The toothed bracket includes a plurality of toothed bars 13 spaced apart in the horizontal direction. Each toothed bar 13 is vertical, and a plurality of uniformly distributed anti-slip teeth 14 are formed at the top of each toothed bar 13. A blanking cavity 5 is formed in the material box 12, and a waste outlet 6 is formed on the outer wall of one side of the material box 12. The toothed bracket is a hollow structure at the top of the carrier table 2. The cabinet panel limiting members include four groups of end angle limiting plates 15 distributed in a matrix. Each group of end angle limiting plates 15 is composed of two vertical plates perpendicular to each other. Vertical limiting baffles 16 are formed on the adjacent two groups of end angle limiting plates 15 far from the linear transport table 1.

[0040] The toothed bracket on the carrier table 2 is used to support the cabinet panel. After the cabinet panel is placed on the toothed bracket, the anti-slip teeth 14 on each toothed bar 13 are used to prevent the cabinet panel from slipping. When the cabinet panel slides from the linear transport table 1 onto the two groups of strip-shaped guide slides 9, one end of the cabinet panel will gradually approach the two limiting baffles 16. Eventually, one end of the cabinet panel will abut against the two limiting baffles 16. At this time, the forward stroke of the cabinet panel is restricted by the two limiting baffles 16. Then, during the process of the cabinet panel descending into the toothed bracket through the two groups of strip-shaped guide slides 9, the four end corners of the cabinet panel will respectively descend into the corresponding four groups of end angle limiting plates 15. Finally, the cabinet panel is positioned through the cooperation of the four groups of end angle limiting plates 15, so as to ensure that the positions of the cabinet panels placed on the carrier table 2 are consistent each time.

[0041] In order to show how the two lifting arms 8 in each group of lifting brackets are lifted and lowered synchronously, the following features are provided:

[0042] Two symmetrically arranged sliding seats 17 are fixedly provided on both sides of the material box 12. Each group of lifting arms 8 is vertical and slidably connected to the corresponding sliding seat 17. A horizontal connecting rod 18 is provided between the two lifting arms 8 in each group of lifting brackets. The two ends of the connecting rod 18 are respectively fixedly connected to the corresponding two lifting arms 8. A plurality of cylinders 19 are equidistantly distributed in the horizontal direction below each connecting rod 18. The output end of each cylinder 19 faces upward and is fixedly connected to the corresponding connecting rod 18.

[0043] The two lifting arms 8 in each group of lifting brackets are integrated through the connecting rod 18. The two lifting arms 8 integrated through the connecting rod 18 are driven to lift and lower by the corresponding plurality of cylinders 19. When the lifting arms 8 lift and lower, the lifting arms 8 will slide in the corresponding sliding seats 17, and the stability of the lifting arms 8 during lifting and lowering is improved through the sliding seats 17.

[0044] To show the specific installation method of each lateral translation arm 10, the following features are provided:

[0045] Each group of lateral translation arms 10 includes two lateral translation plates 20 symmetrically arranged on both sides of the corresponding lifting arm 8. Each lateral translation plate 20 is slidably connected to the corresponding lifting arm 8. A rectangular block 21 is fixedly arranged between two adjacent lateral translation plates 20. A vertically downward convex block 22 is formed at the bottom of the rectangular block 21 (as Figure 11 shown). A horizontal limiting rod 23 is fixedly arranged on the convex block 22. The limiting rod 23 passes through the corresponding lifting arm 8, and a limiting nut 24 is screwed on the end of the limiting rod 23 passing through the lifting arm 8 (as Figure 9 shown).

[0046] Each group of lateral translation arms 10 restricts its own sliding direction through the limiting rod 23, so as to ensure that the lateral translation arm 10 can only move in the horizontal direction. Each group of lateral translation arms 10 prevents itself from rotating through the lateral translation plate 20 slidably connected to the lifting arm 8. When processing the lifting arm 8, sliding grooves 43 are formed on the side arms on both sides of the lifting arm 8 (as Figure 5 shown). The lateral translation plate 20 is connected to the lifting arm 8 by horizontally inserting into the sliding groove 43.

[0047] To show how each group of lateral translation arms 10 performs lateral translation, the following features are provided:

[0048] A horizontal spring 25 is sleeved on each limiting rod 23. The two ends of the spring 25 are respectively in contact with the convex block 22 and the lifting arm 8. A triangular block 26 is formed on each lateral translation plate 20. A vertical strip 27 fixedly connected to the outer wall of the material box 12 is arranged below each triangular block 26 (as Figure 5 shown). A first inclined surface 28 is formed on each triangular block 26, and a second inclined surface 29 that is inclined and matched with the first inclined surface 28 is formed on the top of each vertical strip 27.

[0049] In the initial state, the spring 25 releases elastic force and drives the two lateral translation plates 20 to extend towards the material box 12 through the convex block 22. At this time, the limiting nut 24 screwed on the end of the limiting rod 23 will be in contact with the lifting arm 8 (as Figure 9 shown), so as to prevent the limiting rod 23 from separating from the lifting arm 8 through the limiting nut 24. When the two lateral translation plates 20 are in the extended state, the triangular blocks 26 on each lateral translation plate 20 correspond to the vertical strips 27 below. When the lifting arm 8 is driven to descend by the air cylinder 19, the triangular blocks 26 on each lateral translation plate 20 will gradually approach the vertical strips 27 downward. When the triangular block 26 is in contact with the vertical strip 27, through the cooperation of the first inclined surface 28 and the second inclined surface 29, the lateral translation plate 20 will retract during the descending process. At this time, the corresponding strip-shaped guide and slide 9 is driven to separate from the cabinet board by the retracted lateral translation plate 20.

[0050] To show the specific structure of each group of strip guide slides 9, the following features are set:

[0051] Each group of strip guide slides 9 includes a U-shaped strip plate 30 and a plurality of guide pulleys 31. The U-shaped strip plate 30 is arranged horizontally (as Figure 13 shown), and a plurality of guide pulleys 31 are equidistantly installed in the U-shaped strip plate 30 along the horizontal direction. A vertically upward side baffle 32 is formed on one side of the U-shaped strip plate 30 (as Figure 9 shown).

[0052] Both sides of the linear transport table 1 are fixedly provided with side baffles 44. The side baffles 44 are used to limit the cabinet board on the linear transport table 1. In this way, when the cabinet board slides from the linear transport table 1 to the carrier table 2, the cabinet board will directly slide into the two groups of strip guide slides 9. At this time, both ends of the cabinet board will be blocked by the side baffles 32 on the two U-shaped strip plates 30. The side baffles 32 are used to limit the cabinet board that slides into the strip guide slides 9. After the cabinet board slides into the strip guide slides 9, the plurality of guide pulleys 31 on each group of strip guide slides 9 play a guiding role in the forward movement of the cabinet board.

[0053] To show the specific installation method of the strip guide slides 9, the following features are set:

[0054] An insertion block 33 is fixedly provided at one end of each U-shaped strip plate 30 facing the linear transport table 1, and a rotating shaft 34 is fixedly provided at the other end of each U-shaped strip plate 30 (as Figure 10 shown). A slot 35 is formed on each rectangular block 21 close to the linear transport table 1. Each insertion block 33 is inserted downward into the corresponding slot 35, and each rotating shaft 34 is rotatably connected to the rectangular block 21 far from the linear transport table 1.

[0055] The U-shaped strip plate 30 is rotatably connected to the corresponding rectangular block 21 through the rotating shaft 34, so that the U-shaped strip plate 30 can be flipped. When the U-shaped strip plate 30 is horizontal, the insertion block 33 provided at the other end of the U-shaped strip plate 30 will be inserted downward into the corresponding slot 35. When the rotating shaft 34 is rotatably connected to the rectangular block 21, an axial limiting ring (not shown in the figure) is provided between the rotating shaft 34 and the rectangular block 21 to limit the axial displacement of the rotating shaft 34 on the corresponding rectangular block 21. After the insertion block 33 at one end of the U-shaped strip plate 30 is inserted downward into the slot 35, at this time, the U-shaped strip plate 30 can be regarded as being integrated with the corresponding two groups of transverse moving arms 10. In this way, the U-shaped strip plate 30 can be driven by the transverse moving arms 10 to move horizontally.

[0056] To show the specific structure of the flipping member, the following features are set:

[0057] The flip member includes two sets of symmetrical abutment members, each set of abutment members includes a first fixing pin 36 and a second fixing pin 37, the first fixing pin 36 is horizontally fixedly connected to one end of the corresponding U-shaped strip 30 (such as Figure 5 As shown), the No. 1 fixing pin 36 is close to the rotating shaft 34, the No. 2 fixing pin 37 is horizontally fixedly connected to the corresponding end angle limit plate 15, the No. 2 fixing pin 37 is located above the No. 1 fixing pin 36, and the No. 1 fixing pin 36 and the No. 2 fixing pin 37 are perpendicular to each other.

[0058] After the cabinet panels are laser cut, the finished cabinet panels on the two sets of strip guide slides 9 need to be removed. During this process, the No. 1 fixing pin 36 on the U-shaped strip 30 will gradually approach the No. 2 fixing pin 37 upwards. When the No. 1 fixing pin 36 collides with the No. 2 fixing pin 37, each U-shaped strip 30 is provided with an end of the rotating shaft 34 which will rotate through the rotating shaft 34, and each U-shaped strip 30 is provided with an end of the insert block 33 which will tilt upwards. Finally, the two sets of strip guide slides 9 will be in an inclined state for the cabinet panels to slide down by themselves.

[0059] In order to show the specific structure of the three-axis displacement mechanism, the following features are set:

[0060] The three-axis displacement mechanism includes a moving frame 38, a moving seat 39 and a lifting seat 40. Support frames 41 are fixedly provided on both sides of the material box 12. The two ends of the moving frame 38 are respectively slidably connected to the two support frames 41, the moving seat 39 is slidably connected to the moving frame 38, and the lifting seat 40 is slidably connected to the moving seat 39. The moving frame 38 and the moving seat 39 both slide in the horizontal direction, and the sliding directions of the moving frame 38 and the moving seat 39 are perpendicular to each other. The laser cutting head 11 is fixedly connected to the lifting seat 40.

[0061] The laser cutting head 11 moves along the Z axis through the lifting seat 40 , the laser cutting head 11 moves along the X axis through the moving seat 39 , and the laser cutting head 11 moves along the Y axis through the moving frame 38 .

[0062] Working principle:

[0063] The cabinet board is horizontally placed on the linear transport table 1, and the cabinet board is sent to the laser cutting assembly through the linear transport table 1. The linear transport table 1 is a prior art. Among them, a number of equally spaced retaining bars 42 are formed on the conveyor belt inside the linear transport table 1, and the cabinet board is driven to move forward through the retaining bars 42. When the cabinet board moves to the end of the linear transport table 1, the two lifting arms 8 on each lifting support will synchronously drive the corresponding transverse movement frame to rise. During this process, the two strip-shaped guide sliding frames 9 will synchronously rise to correspond to the cabinet board at the end of the linear transport table 1. After that, the cabinet board at the end of the linear transport table 1 will slide onto the two strip-shaped guide sliding frames 9. At this time, the two ends of the cabinet board are lifted by the two strip-shaped guide sliding frames 9. When the cabinet board is lifted by the two strip-shaped guide sliding frames 9, the two lifting arms 8 on each lifting support will synchronously drive the corresponding transverse movement frame to descend. Then, the cabinet board lifted by the two strip-shaped guide sliding frames 9 will drop onto the carrier table 2. During this process, the cabinet board is limited by the cabinet board limiting member at the top of the carrier table 2. When the cabinet board is placed on the top of the carrier table 2, the two transverse movement arms 10 in each transverse movement frame will synchronously drive the corresponding strip-shaped guide sliding frame 9 to move outward. At this time, the two strip-shaped guide sliding frames 9 move away from each other, so that the end parts of each strip-shaped guide sliding frame 9 corresponding to the cabinet board are separated, preventing the strip-shaped guide sliding frame 9 from affecting the subsequent cutting of the cabinet board by the laser cutting head 11. When the cabinet board is placed on the top of the carrier table 2, the cabinet board is cut by the laser cutting head 11. Among them, the laser cutting head 11 is translated through a three-axis displacement mechanism, so that the laser cutting head 11 can cut different parts of the cabinet board according to the current processing technology. During the cutting process, the cut waste will fall downward through the hollow structure at the top of the carrier table 2 onto the blanking inclined plate 7, and finally the waste will slide to the waste outlet 6 through the blanking inclined plate 7. When the cabinet board is cut, the two transverse movement arms 10 on each transverse movement frame will synchronously drive the strip-shaped guide sliding frame 9 to move towards the end of the cabinet board. At this time, the two strip-shaped guide sliding frames 9 move towards each other. When the strip-shaped guide sliding frame 9 moves to the end of the cabinet board, the lifting arm 8 will drive the corresponding strip-shaped guide sliding frame 9 to rise again. Finally, the two ends of the cabinet board will be lifted by the two strip-shaped guide sliding frames 9 again. When the cabinet board rises close to the flipping member, the flipping member will drive the two strip-shaped guide sliding frames 9 to flip synchronously. During this process, the end of the strip-shaped guide sliding frame 9 inserted into the transverse movement arm 10 will tilt upward, so that the two strip-shaped guide sliding frames 9 will change from a horizontal state to an inclined state. Finally, the cabinet board lifted by the strip-shaped guide sliding frame 9 will slide downward by itself. In the actual use process, a collection box (not shown in the figure) for collecting finished cabinet boards can be installed beside the carrier table 2. When the cabinet board slides out of the strip-shaped guide sliding frame 9, the cabinet board will fall into the collection box for collection. When the cabinet board in front is being cut, the cabinet board on the linear transport table 1 stops conveying. When the cabinet board falls into the collection box after being cut, the two strip-shaped guide sliding frames 9 will move again to correspond to the cabinet board on the linear transport table 1. After that, the cabinet board on the linear transport table 1 will slide onto the two strip-shaped guide sliding frames 9 again, and finally the cutting of a batch of cabinet boards is realized.
