Abstract
Description
Technical Field
[0001] The invention relates to the technical field of laser cutting, and in particular to a fully automatic laser cutting machine for polymer films. Background Art
[0002] There are different types of polymer film, and different types of film have different properties, and there are certain differences in slitting methods. For example, BOPET is a biaxially oriented polyethylene film, which is a high-strength film material made of polyethylene resin and formed by a biaxial stretching process. The commonly used products of BOPET are thin and have the characteristics of high strength and not easy to be stretched. Therefore, they are suitable for laser cutting; laser cutting uses a focused high-power density laser beam to irradiate the material, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Laser cutting is one of the thermal cutting methods and is widely used in the field of steel cutting. It has the characteristics of no burrs on the cut surface and high precision.
[0003] Existing polymer film laser cutting machines have many technical problems when in use. First, when fixing the position of the polymer film, a suction device is generally used to suck the internal air of the conveyor belt to make the two fit together. However, on the one hand, the suction space is too large, resulting in uneven force at each position and poor fitting effect. On the other hand, only the cutting pattern area of the polymer film or the size of the film needs to be fixed, which increases the invalid suction space. Second, wrinkles or curling will occur during the movement of the polymer film on the conveyor belt, thereby affecting subsequent fixation and cutting. Third, static electricity will be generated in the process of the polymer film being transferred to the conveyor belt due to friction, causing the film to stick or drift, which increases the difficulty of precise positioning of the polymer film.
[0004] To sum up, considering that the existing facilities cannot meet the work needs, we propose a fully automatic laser cutting machine for polymer films. Summary of the invention

[0026] The present invention provides a polymer film fully automatic laser cutting machine through improvement, which has the following significant improvements and advantages compared with the prior art: Multiple groups of adsorption boxes are designed to replace the suction of gas in the entire space of the conveyor belt. The adsorption boxes are placed into the inside of the circular conveyor belt in turn. Each adsorption box is fixed on 1-3 groups of movable support rods using rectangular slots, and then the movable support rods are pushed to move to the specified position and then stop. The position is flexibly adjusted, and then a group of joint hoses in the nearest position are connected to the sealing joint at the bottom of the adsorption box. Several groups of adsorption boxes are assembled together to form adsorption areas corresponding to the pattern range. The matrix structure is laid out and spliced according to the pattern range or the size of the film, which streamlines and effectively creates an effective suction space. The negative pressure in each adsorption box is very uniform, which can evenly adsorb each area of the film, improve the fitting effect of the film, and also improve the effect of laser cutting.
[0027] To design a film press, first start the small hydraulic cylinder. The hydraulic rod drives the pressing wheel on the film pressing seat downward to contact the surface of the polymer film. Then start the screw motor. The bidirectional screw rotates at a uniform speed, causing the film presses on the positive spiral pattern and the reverse spiral pattern to move synchronously and oppositely in a straight line. During the horizontal movement of the film press, first use and exclude the film pushing sheet on the wrinkle rod to jointly flatten the wrinkled or curled film area, and then use the pressing effect of the pressing wheel to ensure that the nearby area remains flat during the film pushing process, until the two groups of film presses move to the edge of the polymer film respectively, and automatically correct the wrinkled or curled film.
[0028] The film press is designed. When the polymer film completely enters the designated position at the upper end of the circular conveyor belt, the four groups of film presses are moved to the edge of the polymer film respectively. The pressing wheels are pressed on the polymer film. The four groups of film presses position the four corners of the polymer film to prevent it from shifting during the laser cutting process, thereby further improving the fixing effect of the film.
[0029] Start several groups of ion fans, blow out ion wind from the ion air outlet, and guide it into the ion air duct below through the air inlet channel. The ion wind gathered in the ion air duct is blown downward from several groups of wind gathering holes, and continuously blows directly to the polymer film moving directly below to neutralize the positive and negative charges of static electricity on the film, thereby achieving the purpose of eliminating static electricity and solving the problem of film adhesion or drift due to static electricity.

The lower end of the laser cutting head module 13 is respectively installed with a laser cutting head 14 and a water cooler 15. The water cooler 15 cools down the condenser on the laser cutting head module 13. Figure 1-3 shown.
[0035] Furthermore, a sprocket drive structure 2 is provided inside the frame 1, an annular conveyor belt 3 is installed around the outer side of the sprocket drive structure 2, and a plurality of groups of adsorption boxes 20 acting on the annular conveyor belt 3 are laid inside the annular conveyor belt 3. The adsorption boxes 20 are all rectangular in shape, and a plurality of groups of adsorption boxes 20 are assembled to form an adsorption area, and are arranged in a matrix structure (a maximum of two groups of adsorption boxes 20 can be accommodated side by side with the same width), such as Figure 2 shown.
[0036] In this embodiment, an adsorption chamber is provided inside the adsorption box 20, and a plurality of groups of air suction holes 21 are evenly provided on the upper end surface of the adsorption box 20. The air suction holes 21 are close to the inner surface of the endless conveyor belt 3, but are not attached to avoid interfering with the movement of the endless conveyor belt 3. The endless conveyor belt 3 itself is a breathable structure. Figure 4 shown.
[0037] In this embodiment, a clamping groove 28 for acting on the joint hose 34 is provided in the middle area of the lower end surface of the adsorption box 20. The clamping groove 28 clamps a part of the joint hose 34 to prevent it from contacting the lower parts. A sealing joint 26 is installed in the clamping groove 28. A plurality of groups of rectangular clamping grooves 22 are provided on both sides of the lower end surface of the adsorption box 20 at equal distances. The rectangular clamping grooves 22 are provided for the movable support rods 23 to be horizontally buckled. The movable support rods 23 support the adsorption box 20, such as Figure 4 and 5 shown.
[0038] Further, the cross section of the movable support rod 23 is the same as the rectangular slot 22, and wheel bearings are installed at both ends of the movable support rod 23, and a wheel axle 24 is installed on the wheel bearing. The end of the wheel axle 24 is connected to a guide wheel 25, and each set of guide wheels 25 is located on a wheel rail 27, and the wheel rail 27 is laid inside the frame 1 along the direction of the endless conveyor belt 3. The guide wheel 25 carries a self-locking device, which can automatically lock the guide wheel 25 to prevent it from rolling, such as Figure 5 shown.
[0039] Furthermore, an air pump assembly 30 is installed inside the side wall of the frame 1 and outside the sprocket drive structure 2. Figure 4 shown.
[0040] Specifically, the connecting pipe 31 on the vacuum pump group 30 is connected to the gas distribution main pipe 32, and the end of the gas distribution main pipe 32 away from the connecting pipe 31 is fixed by a pipe rack 33 and the inner wall of the frame 1. A plurality of joint hoses 34 (the length of the joint hoses 34 is sufficient) are installed on the upper end of the gas distribution main pipe 32. The joint hoses 34 extend from the outer side of the endless conveyor belt 3 to the middle position of the frame 1 and are connected to the sealing joint 26. Figure 4 shown.
[0041] Furthermore, fixed support plates 40 are symmetrically arranged at both ends of the frame 1 and above the endless conveyor belt 3, and film laying boxes 41 are riveted to the middle of the two sets of fixed support plates 40. Figure 1 and 6 shown.
[0042] Among them, the bottom of the film laying box 41 is provided with a strip groove 42, the length of which is designed to be greater than the width of the polymer film, and a bidirectional screw rod 43 is rotatably arranged in the middle position of the strip groove 42. Figure 7 shown.
[0043] Among them, one end of the bidirectional screw rod 43 is fixed by the bearing seat 44 and the box wall of the film laying box 41, and the other end of the bidirectional screw rod 43 is connected to the screw motor 46 through the coupling. The screw motor 46 is set through the outer side of the film laying box 41, and the position of the bidirectional screw rod 43 near the screw motor 46 is sleeved with an inner bearing 45, which plays the role of connection limit. Figure 7 and 8 shown.
[0044] Among them, the bidirectional screw rod 43 is symmetrically distributed with positive spiral patterns 47 and reverse spiral patterns 48, and the film pressing device 9 is symmetrically installed at the positions of the positive spiral patterns 47 and the reverse spiral patterns 48. Figure 8 shown.
[0045] Specifically, the film pressing device 9 includes a moving seat 91, a screw nut sleeve 92, a small hydraulic cylinder 93 and a hydraulic rod 94. Fig. 9 shown.
[0046] In this embodiment, a screw nut sleeve 92 (the interior of the screw nut sleeve 92 includes a screw nut with spiral motion) is installed horizontally through the middle of the movable seat 91 and acts on the forward spiral pattern 47 or the reverse spiral pattern 48. A small hydraulic cylinder 93 is fixed downward inside the movable seat 91, and a hydraulic rod 94 is arranged inside the small hydraulic cylinder 93 so as to move downward.
[0047] Furthermore, the film pressing device 9 also includes a film pressing seat 95, a pressing wheel 96, a wrinkle removing rod 97 and a film pushing sheet 98. Fig. 9 shown.
[0048] In this embodiment, a film pressing seat 95 is welded to the lower end of the hydraulic rod 94. The film pressing seat 95 is matched with the strip groove 42. The film pressing seat 95 moves linearly along the strip groove 42 to play a guiding role. Several groups of pressing wheels 96 are evenly installed inside the film pressing seat 95. Parts of the pressing wheels 96 extend out of the film pressing seat 95. The pressing wheels 96 act on the surface of the polymer film. The pressing wheels 96 include a pressing wheel shaft and two groups of positioning bearings. The pressing wheel shaft drives the pressing wheel 96 to move.
[0049] In this embodiment, a wrinkle removal rod 97 is provided on one side of each group of pressing wheels 96. The wrinkle removal rod 97 is obliquely installed at the bottom of the film pressing seat 95. A film pushing sheet 98 is provided at the lower end of the wrinkle removal rod 97. The film pushing sheet 98 is made of plastic material and does not damage the film when in contact with the film. The film pushing sheet 98 and the bottom of the pressing wheel 96 are at the same horizontal height.
[0050] The wrinkle removal rods 97 on the two groups of film pressing devices 9 are inclined in opposite directions and are in an "eight" shape.
[0051] Furthermore, the motion adjustment module 4 also includes an inkjet device, which pre-draws lines to draw the required image.
[0052] When this embodiment is in use, the laser cutting head module 13 is used to cut the range of the pattern on the polymer film or the size of the film as needed. The adsorption boxes 20 are first placed in the interior of the circular conveyor belt 3 in sequence, and each adsorption box 20 is fixed on 1-3 groups of movable support rods 23 using a rectangular slot 22. Then, the movable support rods 23 are pushed to move to a specified position and then stopped. Then, a group of joint hoses 34 at the nearest position are connected to the sealing joint 26 at the bottom of the adsorption box 20 (part of the joint hose 34 is fixed in the clamping tube groove 28). Several groups of adsorption boxes 20 are assembled together to form an adsorption area corresponding to the pattern range (the adsorption boxes 20 are placed in close contact with each other in a matrix structure layout).
[0053] In the process of the polymer film entering the endless conveyor belt 3, wrinkles or curling will occur. At this time, the two groups of film presses 9 are initially in the middle position of the strip groove 42, that is, the center position just above the polymer film. First, start the small hydraulic cylinder 93, and the hydraulic rod 94 extends downward, driving the pressing wheel 96 on the film pressing seat 95 to contact the surface of the polymer film downward (at the same time, the film pusher 98 also contacts the film surface), and then start the screw motor 46, which drives the bidirectional screw 43 to rotate at a uniform speed, causing the film presses 9 on the forward spiral pattern 47 and the reverse spiral pattern 48 to synchronously move in opposite directions (the screw nut sleeves 92 on the two groups of film presses 9 act on the forward spiral pattern 47 and the reverse spiral pattern 48 respectively). In the process of the horizontal movement of the film press 9, the wrinkle rod 96 is first used to eliminate the wrinkle. The film-pushing pieces 98 on 97 jointly push flat the wrinkled or curled film area, and then use the pressing effect of the pressing wheel 96 to ensure that the nearby area remains flat during the film pushing process (the film is pushed synchronously from the middle to both sides), until the two groups of film presses 9 move to the edge of the polymer film respectively, and the hydraulic rod 94 drives the film press 9 to rise (the pressing wheel 96 and the film-pushing piece 98 are separated from the film), so that the two groups of film presses 9 move back to the middle position of the strip groove 42, and repeat the film pressing process again, and so on. After the polymer film completely enters the designated position at the upper end of the endless conveyor belt 3, the four groups of film presses 9 move to the edge of the polymer film respectively, and the pressing wheel 96 presses on the polymer film. The four groups of film presses 9 position the four corners of the polymer film to prevent it from being displaced during the laser cutting process.
[0054] During the polymer film cutting process, the vacuum pump group 30 is started, and acts on the air distribution main pipe 32 and several groups of joint hoses 34 in turn, and air is sucked from several groups of adsorption boxes 20 respectively. The adsorption box 20 uses several groups of suction holes 21 to suck the gas in the circular conveyor belt 3, forming a negative pressure effect, and adsorbing the polymer material film on the upper surface of the circular conveyor belt 3, fully fitting it to achieve a further fixation effect. Then the inkjet device first draws the line to draw the required image, and the laser cutting head module 13 moves on the inner track 11. The laser cutting head 14 cuts according to the pre-set pattern, and the cut pattern is separated manually or mechanically. Embodiment 2
[0055] On the basis of the first embodiment, the polymer film will generate static electricity due to friction during the transfer to the endless conveyor belt 3, causing the film to stick or drift, making it more difficult to accurately position the polymer film. In order to solve the above problems, we have the following design, such as Figure 10-12 shown.
[0056] Specifically, a gap 51 is provided at the bottom of the motion adjustment module 4, a cross seat 50 is riveted in the gap 51, and the gap 51 covers the upper end surface of the film laying box 41 under the movement condition of the motion adjustment module 4, and a plurality of groups of ion fans 52 are equidistantly installed on the cross seat 50, and an ion air outlet 53 is provided at the lower end of each group of ion fans 52, such as Fig.10 and 11 shown.
[0057] Furthermore, a plurality of air inlet channels 54 connected to the ion air outlets 53 are provided upwardly in the film laying box 41 near the feeding end of the endless conveyor belt 3. Fig.10 shown.
[0058] In this embodiment, an ion air duct 55 is horizontally installed at the bottom of the film laying box 41 and on the side of the strip groove 42. The length of the ion air duct 55 is designed to be equal to the width of the polymer film. The ion air duct 55 is connected to each group of air inlet channels 54. The lower end surface of the ion air duct 55 is equidistantly provided with a plurality of groups of air gathering holes 56 acting on the polymer film to increase the force of the ion wind. Fig.12 shown.
[0059] When this embodiment is in use, during the process of transferring the polymer film to the endless conveyor belt 3, the motion adjustment module 4 is moved to the left along the horizontal track 60 until the gap 51 covers the upper end surface of the film laying box 41 (the horizontal seat 50 is attached to the upper end surface of the film laying box 41), and several groups of ion air vents 53 are respectively connected with the air inlet channels 54 on the film laying box 41, and several groups of ion fans 52 are started to blow out ion wind from the ion air vents 53, which are guided into the ion wind duct 55 below through the air inlet channels 54. The ion wind gathered in the ion wind duct 55 is blown downward from several groups of wind gathering holes 56, and the polymer film moving directly below is continuously and directly blown to neutralize the positive and negative charges of static electricity on the film, thereby achieving the purpose of eliminating static electricity.
