Description

Technical Field

[0001] This application relates to the field of laser die-cutting machine technology, and in particular to a laser integrated double-sided die-cutting machine. Background Technology

[0002] Laser die cutting is computer-controlled laser cutting, and is not limited by the complexity of the graphic. It can cut requirements that traditional die cutting cannot achieve. There is no need to change the die plate, and it can quickly switch between different pattern jobs, saving the time of die changing and adjusting the die in traditional die cutting. It is especially suitable for short-run and personalized die cutting processing. The cutting graphic design can be completed on the computer, and the corresponding pattern can be cut out by the laser die cutting machine.

[0003] Due to the characteristics of laser die-cutting machines, they are very suitable for processing patterns on screens. For printing screens, to improve the quality of the patterns, double-sided laser cutting is often used, processing the patterns on both sides of the screen separately.

[0004] Regarding the aforementioned technologies, the inventors believe that current laser die-cutting machines require manual flipping of the workpiece after processing one side of the screen, and the workpiece also needs to be re-clamped during the process, resulting in a large amount of manual labor and low efficiency. Summary of the Invention

[0005] This application provides a laser integrated double-sided die-cutting machine that can automatically flip the workpiece, reducing manual labor and eliminating the need for repeated workpiece clamping during the process, thus improving efficiency.

[0006] This application provides a laser-integrated double-sided die-cutting machine, which adopts the following technical solution: A laser integrated double-sided die-cutting machine includes a frame and a laser body. A worktable is fixed to the frame, and two mounting seats are symmetrically fixed on the worktable. Each mounting seat has a sliding block. Each mounting seat is equipped with a servo motor and a lead screw driven by the servo motor. The lead screw is threaded to the slide block. A rotating rod is rotatably connected to the slide block. A mounting frame for mounting workpieces is fixed on the rotating rod. A ratchet is coaxially fixed to the rotating rod. Multiple ratchet teeth are rotatably connected to the worktable, and these teeth are linearly distributed along the sliding direction of the slide block. The ratchet teeth are used for ratchet engagement. A support surface is provided on the front side of the top surface of the worktable, which abuts against the lower surface of the mounting frame. A rotating groove is provided on the rear side of the top surface of the worktable for rotating the mounting frame.

[0007] By adopting the above technical solution, after the workpiece is placed in the mounting frame, the servo motor drives the lead screw to rotate. The lead screw, through a threaded connection, drives the slide to move. After the mounting frame and workpiece move directly below the laser body, the laser body, under program control, die-cuts a pattern on the workpiece. After processing one side of the workpiece, the slide is controlled to move backward on the worktable. When the ratchet begins to contact the ratchet teeth, the ratchet teeth, through their unidirectional rotation characteristic, drive the ratchet to rotate, thereby driving the rotating rod and mounting frame to rotate. After the mounting frame begins to rotate, it enters the rotating groove, and the mounting frame rotates exactly 180 degrees, completing the flipping. Then, the slide is controlled to move forward on the worktable, which can send the flipped workpiece back below the laser body, thus completing the processing of the other side of the workpiece.

[0008] Optionally, the slide is fixed with a bracket, a magnetic strip is fixed to the side of the bracket facing the mounting frame, and iron strips are fixed to both sides of the outer wall of the mounting frame, with the iron strips positioned close to the magnetic strip.

[0009] By adopting the above technical solution, after the mounting frame is flipped over, the magnetic attraction between the iron strip and the magnetic strip keeps the mounting frame in a horizontal state, achieving the effect of automatic correction and angle stabilization.

[0010] Optionally, the mounting frame includes a slidingly connected half-frame one and half-frame two, both of which are U-shaped. Half-frame one is fixed to the rotating rod, and a tension spring connects half-frame one and half-frame two.

[0011] By adopting the above technical solution, the elastic force of the tension spring drives half-frame one and half-frame two to move closer to each other to clamp the workpiece, and it can also be adapted to workpieces of different lengths.

[0012] Optionally, the workbench is fixed with an electronic pin, and the side wall of the second half-frame is provided with a positioning hole for the electronic pin to be inserted.

[0013] By adopting the above technical solution, when picking up or placing workpieces, after the mounting frame moves forward to the limit, the electronic pin is inserted into the positioning hole to prevent the second half of the frame from sliding. Then, the servo motor drives the first half of the frame to move backward, so that the first half of the frame and the second half of the frame can move away from each other, making it easier to put or take out workpieces into the mounting frame.

[0014] Optionally, the inner walls of the two half-frames facing each other are provided with limiting grooves, and the limiting grooves are arranged in a multi-level gradient.

[0015] By adopting the above technical solution and using multi-level limiting grooves, it is possible to adapt to workpieces of various thicknesses and specifications, thereby improving applicability.

[0016] Optionally, two sets of servo motors and lead screws are provided, with the two lead screws located on the left and right sides of the mounting frame respectively, and the two servo motors working synchronously.

[0017] By adopting the above technical solution, two sets of servo motors and lead screws are used to ensure that the slides on both sides of the mounting frame are evenly stressed, thereby improving the stability of movement.

[0018] Optionally, clearance grooves are provided in the middle of both sides of the first and second half-frames, the middle horizontal bar of the first and second half-frames does not contact the supporting surface, the two side vertical bars of the first and second half-frames are used to contact the supporting surface, and the supporting surface is fixed with a wear-resistant layer of polytetrafluoroethylene at the position where it contacts the first and second half-frames.

[0019] By adopting the above technical solution, through the avoidance groove and wear-resistant layer, the sliding contact point between the mounting frame and the worktable is only on the wear-resistant layer, avoiding wear on other parts of the support surface caused by the mounting frame, and preventing wear on the glass plate on the support surface. The wear-resistant layer made of polytetrafluoroethylene has self-lubricating properties, reducing sliding resistance and reducing wear on the contact points of the mounting frame.

[0020] Optionally, the top bevel of the ratchet is inclined toward the rear of the worktable, and a spring is installed between the ratchet and the worktable, the spring force driving the ratchet to rotate upward.

[0021] By adopting the above technical solution, the spring provides an upward rotational force to the ratchet, and the ratchet and ratchet wheel are combined into a one-way drive structure. When the slide moves to the rear of the worktable, the ratchet can drive the ratchet wheel to rotate, thereby driving the rotating rod and the mounting frame to rotate; when the slide moves to the front of the worktable, the ratchet will not drive the ratchet wheel to rotate.

[0022] Optionally, the support surface is provided with an inclined guide surface near the end edge of the rotating groove.

[0023] By adopting the above technical solution, after the mounting frame is flipped over in the rotating groove, the mounting frame moves towards the worktable, and the guide surface ensures that the front end of the mounting frame can be moved onto the support surface.

[0024] Optionally, a top groove is provided through the front end of the support surface, and the top groove is located outside the frame.

[0025] By adopting the above technical solution, the top groove allows the workpiece to be easily lifted from below the worktable by hand, thus facilitating the removal of the workpiece from the mounting frame.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. It can automatically flip the workpiece, reducing manual labor and eliminating the need for repeated workpiece clamping, thus improving efficiency; 2. When picking up and placing workpieces, half-frame one and half-frame two can automatically move away from each other, making it easier to pick up and place workpieces. The mounting frame can adapt to workpieces of different lengths and thicknesses, thus improving the processing range. 3. The workpiece is rotated via a rotating slot, and the rotating part of the workpiece avoids the area below the laser body. Therefore, it will not affect the normal use of the laser body, nor will it affect the layout and use of the device under the worktable. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1 This embodiment discloses a laser integrated double-sided die-cutting machine, including a frame 1 and a laser body 11. The frame 1 is fixed with a worktable 2, and the laser body 11 is located above the worktable 2.

[0031] Reference Figure 1 and Figure 2 Two mounting seats 3 are symmetrically fixed on the workbench 2. Each mounting seat 3 has a sliding block 31, and the inner wall of the mounting seat 3 has a groove for the sliding block 31 to slide. Each mounting seat 3 is equipped with a servo motor 32 and a lead screw 33 driven by the servo motor 32. The lead screw 33 is rotatably connected to the mounting seat 3 and threadedly connected to the sliding block 31. Two sets of servo motors 32 and lead screws 33 are provided, with the two lead screws 33 located on the left and right sides of the mounting frame 4 respectively. The two servo motors 32 work synchronously and start and stop synchronously, driving the two sliding blocks 31 to slide synchronously. The stopping position after sliding is precisely controlled by the controller.

[0032] Reference Figure 2 and Figure 3 The slide block 31 is rotatably connected to a rotating rod 34. A mounting frame 4 for mounting workpieces is fixed on the rotating rod 34. The mounting frame 4 includes two slidably connected half-frames 41 and 42. Both half-frames 41 and 42 are U-shaped, with a horizontal bar in the middle and vertical bars on both sides. Half-frames 41 and 42 are slidably connected by dovetail grooves and dovetail blocks on the vertical bars. Half-frame 41 is fixed to the rotating rod 34. A tension spring 43 connects half-frames 41 and 42. The spring force of the tension spring 43 drives half-frames 41 and 42 closer together to clamp the workpiece and accommodate workpieces of different lengths.

[0033] The inner walls of the two opposing semi-frames 41 and 42 are provided with limiting grooves 44, which are arranged in a multi-level gradient. The limiting grooves 44 are specifically opened on the inner side of the crossbar of the U-shaped structure. Through the multi-level limiting grooves 44, it can be adapted to workpieces of various thicknesses, improving applicability. Thicker workpieces are inserted into the outer limiting grooves 44, and thinner workpieces are inserted into the deeper limiting grooves 44.

[0034] The top front of the workbench 2 is provided with a support surface 21, which is used to abut against the lower surface of the mounting frame 4. The rear side of the top surface of the workbench 2 is provided with a rotating groove 22 for the mounting frame 4 to be flipped. The two sides of the first half-frame 41 and the second half-frame 42 are provided with clearance grooves 45. The clearance grooves 45 are specifically opened on the crossbar of the U-shaped structure. Through the design of the clearance grooves 45, the middle crossbar of the first half-frame 41 and the second half-frame 42 does not contact the support surface 21. The two side vertical bars of the first half-frame 41 and the second half-frame 42 are used to contact the support surface 21. The support surface 21 is fixed with a wear-resistant layer 23 of polytetrafluoroethylene at the position where it contacts the first half-frame 41 and the second half-frame 42.

[0035] Through the clearance groove 45 and the wear-resistant layer 23, the sliding contact position between the mounting frame 4 and the worktable 2 is only on the wear-resistant layer 23, which avoids the mounting frame 4 from causing wear on other positions of the support surface 21 and will not wear the glass plate on the support surface 21. The wear-resistant layer 23 made of polytetrafluoroethylene has self-lubricating properties, which reduces sliding resistance and reduces wear on the contact position of the mounting frame 4.

[0036] Reference Figure 2 and Figure 4A ratchet 35 is coaxially fixed to the rotating rod 34. Multiple ratchet teeth 5 are rotatably connected to the worktable 2. These ratchet teeth 5 are linearly distributed along the sliding direction of the slide 31 and are used to engage with the ratchet 35. Specifically, the top slope of the ratchet teeth 5 faces the rear of the worktable 2. A spring 51 is installed between the ratchet teeth 5 and the worktable 2. The elastic force of the spring 51 drives the ratchet teeth 5 to rotate upwards. When the slide 31 moves towards the rear of the worktable 2, and the ratchet 35 begins to contact the ratchet teeth 5, the ratchet teeth 5, through their unidirectional rotation characteristic, drive the ratchet 35 to rotate, thereby causing the rotating rod 34 and the mounting frame 4 to rotate. After the mounting frame 4 begins to rotate, it enters the rotating groove 22. By controlling the displacement distance of the slide 31, the mounting frame 4 rotates exactly 180 degrees, completing the flipping. When the ratchet 35 moves towards the front of the worktable 2, the ratchet 35 presses down on the ratchet teeth 5, compressing the spring 51. At this time, the ratchet teeth 5 do not drive the ratchet 35 to rotate.

[0037] Reference Figure 2 and Figure 3 The slide block 31 is fixed with a bracket 36. A magnetic strip 37 is fixed to the side of the bracket 36 facing the mounting frame 4. Iron strips 46 are fixed to both sides of the outer wall of the mounting frame 4, and the iron strips 46 are positioned close to the magnetic strip 37. Through the magnetic attraction between the iron strips 46 and the magnetic strips 37, when the mounting frame 4 rotates to a horizontal position, it can be maintained in a horizontal position by magnetic force, thus achieving the effect of automatic correction and angle stabilization.

[0038] Reference Figure 1 and Figure 2 A top groove 24 is provided through the front end of the support surface 21. The top groove 24 is located outside the frame 1. The top groove 24 facilitates the lifting of the workpiece from below the worktable 2 by hand, thereby making it easier to remove the workpiece from the mounting frame 4. An inclined guide surface 25 is provided at the end edge of the support surface 21 near the rotating groove 22. After the mounting frame 4 is flipped in the rotating groove 22, the mounting frame 4 moves towards the worktable 2. The guide surface 25 ensures that the front end of the mounting frame 4 can move onto the support surface 21.

[0039] The workbench 2 is fixed with an electronic latch 6, and the side wall of the semi-frame 42 is provided with a positioning hole 47 for the electronic latch 6 to be inserted. The electronic latch 6 is also known as an electric latch, and there are two electronic latches 6 arranged symmetrically on the left and right sides.

[0040] The implementation principle of a laser integrated double-sided die-cutting machine according to an embodiment of this application is as follows: When picking up or placing workpieces, after the mounting frame 4 moves forward to the limit, the electronic pin 6 is inserted into the positioning hole 47 to prevent the second half-frame 42 from sliding. Then, the servo motor 32 drives the first half-frame 41 to move backward, so that the first half-frame 41 and the second half-frame 42 move away from each other, making it easier to put or take up workpieces into the mounting frame 4. The mounting frame 4 is located at the front end of the worktable 2 and partially protrudes from the frame 1, which facilitates the picking up and placing of workpieces.

[0041] After the workpiece is installed in the mounting frame 4, the electronic pin 6 retracts, and the servo motor 32 drives the lead screw 33 to rotate. The lead screw 33 moves the slide block 31 through the threaded connection. Through the two sets of servo motors 32 and lead screws 33, the slide blocks 31 on both sides of the mounting frame 4 are evenly stressed, improving the stability of the movement. After the mounting frame 4 and the workpiece move to directly below the laser body 11, the laser body 11 is controlled by the program to die-cut a pattern on the workpiece.

[0042] Reference Figure 5 After machining one side of the workpiece, the slide block 31 is moved to the rear of the worktable 2. When the ratchet 35 begins to contact the ratchet tooth 5, the ratchet tooth 5 drives the ratchet 35 to rotate due to its unidirectional rotation, thereby driving the rotating rod 34 and the mounting frame 4 to rotate. After the mounting frame 4 begins to rotate, it enters the rotating groove 22. By controlling the displacement distance of the slide block 31, the mounting frame 4 is rotated exactly 180 degrees to complete the flipping. After the flipping is completed, the mounting frame 4 is kept in a horizontal state by the magnetic attraction between the iron strip 46 and the magnetic strip 37.

[0043] Then, control the slide 31 to move forward on the worktable 2, so that the flipped workpiece can be sent back to the bottom of the laser body 11, thereby completing the processing of the other side of the workpiece. After processing is completed, control the slide 31 to move backward on the worktable 2, then rotate the mounting frame 4 180 degrees to reset, and then control the slide 31 to move back to the front end of the worktable 2. Then the workpiece in the mounting frame 4 can be taken out, thus completing the double-sided die-cutting processing of the workpiece.

[0044] In summary, this laser integrated double-sided die-cutting machine achieves automatic workpiece flipping through linear displacement of the slide block 31, reducing manual labor and eliminating the need for repeated workpiece clamping, thus improving efficiency. Furthermore, during workpiece loading and unloading, half-frame 41 and half-frame 42 automatically move away from each other, facilitating workpiece handling. The mounting frame 4 can accommodate workpieces of different lengths and thicknesses, expanding the processing range. The workpiece rotates via the rotating slot 22, with the rotating part avoiding the area below the laser body 11. Therefore, it does not affect the normal operation of the laser body 11, nor does it affect the layout and use of the device below the worktable 2.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
