[0033] The film release adjustment mechanism 52 includes a second slide rail 59 arranged on the connecting plate 48 above the roll film 51, and the second slide rail 59 is provided with two second sliders 60 that can slide along the second slide rail 59, and each second slider 60 is provided with a first cylinder 61 extending downward at the front end, and a film pressing roller 62 is provided at the bottom of the extended end of the first cylinder 61. The film pressing roller 62 is pressed on the roll film 51, and the roll film 51 will stop at different positions according to the size of the plate, ensuring that the start and stop film marks remain on the waste material between the plates, eliminating the hidden marks on the plate surface.

[0034] The discharging and edge trimming mechanism 5 includes a discharging port 63 arranged at the tail end of the transport mechanism 8, a transition roller group 64 arranged at the discharging port 63, and a waste material winder 65 arranged above the transition roller group 64. The waste material winder 65 includes a fixed seat 66 fixed on the frame 1, a winding shaft 67 arranged on the fixed seat 66, and a fifth motor 68 fixed on the frame 1 and drivingly connected to one end of the winding shaft 67.

[0035] The laser 18 is a CO2 metal tube laser.

[0036] When in use, in the first step, after the edge grinding and surface cleaning, the substrate is conveyed to the second roller group 24 through the feeding roller group 23. After the substrate is in place, the signal is automatically sent to the PLC controller;

[0037] In the second step, the controller controls the third motor 43 and the first cylinder 61. The first cylinder 61 is lifted and basically lifted off the second roller group 24. The third motor 43 drives the correction mechanism 32 to complete the width direction correction of the substrate to ensure that the center line of the substrate is perpendicular to the film pressing roller group 47, providing a stable basic position for the subsequent film cutting CCD positioning. After the substrate is positioned in the width direction, the controller controls the second roller group 24 to transport the substrate to the set position and stop to complete the length direction positioning. This position ensures the most economical spacing between the front and rear plates, reduces the waste of the film, and ensures that the previous substrate can completely pass the pressing roller to avoid indentation. At the same time, it provides a stable basic position for the subsequent film cutting CCD positioning;

[0038] In the third step, the PLC command synchronously activates the second roller group 24 to transport the film to the film pressing roller group 47 of the film laminating mechanism 3. At the same time, the film must be prepared before laminating. The film roll 51 passes between the second upper roller 55 and the second lower roller 56 through the tensioning mechanism 46. As the substrate passes between the second upper roller 55 and the second lower roller 56, the film is attached to the substrate, completing the film lamination. After the tail of the substrate exits the film pressing roller group 47, the second roller group 24 is stopped and the fourth motor 58 is turned on. The above steps are repeated to complete the batch laminating process. This film laminating method does not cut the film before lamination, which can maintain stable film tension and contact angle between the film and the substrate. Therefore, regardless of the thickness of the substrate, the deformation amount, or the strength of the adhesive, bubbles and wrinkles will not be generated. At the same time, the film is applied at a constant speed through the film pressing roller, and the film pressing roller does not stop on the substrate surface. Therefore, the problem of strict printing and residual adhesive after the film is removed from the impression point of traditional film lamination is eliminated.

[0039] In the fourth step, after the film is applied, the substrate is sent to the bottom of the CCD camera 22 through the transport mechanism 8. The CCD camera 22 scans the outer dimensions of the film-applied substrate, performs special calculations, and generates a cutting model based on the set shrinkage dimensions, and sends it to the linear motor module;

[0040] In the fifth step, the laser controller controls the on / off and energy level of the laser 18. The XY axis module drives the cutting head 17 to form a moving trajectory according to the cutting model generated in the fourth step to ensure the cutting accuracy. While cutting, the CCD camera 22 scans the substrate and updates the cutting model from time to time to ensure that the dimensional deviation of the substrate will not be accumulated on the deviation of the film cutting, and to ensure that the error between the edge of the film and the edge of the plate after film cutting is always maintained within ≤ the set value ±0.1mm.

[0041] The sixth step is to start the first motor 14 through the PLC instruction to drive the first roller 12 of the transport mechanism 8 to rotate, and send the substrate after the film cutting is completed to the discharge port 63. The substrate that completes the entire film laminating process is transported to the discharge section, and the following inspection process is carried out. The above process is repeated to complete batch production. At the same time, the winding shaft 67 on the waste material winding machine 65 rotates to complete the winding of the waste material. The first piece requires manual assistance to stick the waste material to the winding tube core prepared in advance and placed on the winding shaft 67. The collection adopts the speed + tension control mode to ensure that the waste material is not pulled and broken and can be collected neatly.

[0042] The utility model adopts the above structure to achieve the following beneficial effects: the utility model provides a laser cutting metal substrate laminating machine, which adopts a CCD visual positioning system to perform repeated precision scanning on the metal substrate, and the repeated precision can reach ≤0.1mm, and cooperates with the laser film cutting mechanism for precise cutting. At the same time, the use of special laser cutting on the laminating equipment can cut the film without damaging the substrate. The film release adjustment mechanism added to the roll film can eliminate the residual glue after film removal and the hidden marks in the film, effectively solving the pollution of the residual glue on the equipment and products, reducing the efficiency and waste of the film caused by more than 2% of the poor rework of the film, and can paste various types of films such as PVC, PET, PI, etc., to achieve a laminating process in which the film is smaller than the substrate and of any size.

Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
