Description

Technical Field

[0001] The utility model relates to the technical field of solar film cutting devices, in particular to an automatic solar film cutting device. Background Art

[0002] Solar film is also called heat insulation film. It is made of aluminum, gold, copper, silver and other metals into multi-layer dense high heat insulation metal film through vacuum spraying or magnetron sputtering technology. The free electrons in the outer shell of metal materials are generally not bound by the nucleus. When irradiated by light waves, the electric field of the light waves causes the free electrons to absorb the energy of the light and produce oscillations with the same frequency as the light. This oscillation emits light with the same frequency as the original light, which is called light reflection. The higher the conductivity of the metal, the shallower the penetration depth and the higher the reflectivity. These metal layers will selectively reflect back various heat energy sources in the sun, including infrared, ultraviolet and visible light heat energy, and then release them outward for the second time after the color on the film absorbs the solar heat radiation. With the flow of outdoor air, part of the heat is taken away, thus effectively playing a role of heat insulation.

[0003] Solar film is widely used in life due to its light filtering and heat insulation properties, so it needs to be processed and cut into different shapes and contours so that it can perfectly fit the car window to be protected and provide heat insulation, UV protection and other protective functions. Currently, the commonly used cutting methods are laser cutting and manual cutting. Laser cutting is a non-contact cutting technology that can provide higher cutting accuracy and less heat-affected zone, thereby avoiding damage to solar film and car glass. Laser cutting has fast processing speed, neat cutting edges, a cutting seam width of less than 30 microns, and a heat impact of less than 10 microns. It is a more advanced and efficient cutting method. Traditional manual cutting relies on manual use of blades, which is low in cost, but may leave scratches on the glass surface, and its cutting accuracy and cutting efficiency are low.

A plurality of rectangular grooves 302 are provided on the inner surface of the feeding belt 3, and the spacing thereof corresponds to the spacing of the teeth of the ratchet 12. The first motor 4 drives the feeding belt 3 to rotate. The ratchet 12 cooperates with the rectangular grooves 302 to prevent the feeding belt 3 from slipping and ensure accurate transmission.

[0032] In the preferred embodiment, the structure of the two-axis slide is as follows: two longitudinal guide rails 14 are symmetrically arranged at the upper end of the frame 1, a transverse guide rail 15 is vertically arranged between the two longitudinal guide rails 14, both ends of the transverse guide rail 15 are slidably connected to the longitudinal guide rail 14 through a first slider 16, and the laser cutting head 5 is slidably connected to the transverse guide rail 15 through a second slider 17.

[0034] The two-axis slide mechanism uses fewer mechanical parts and is easy to install and maintain.

[0041] In the preferred embodiment, both ends of the receiving roller 9 are rotatably connected to one side of the frame 1 through the support arm 28, and one end extends out of the support arm 28 and is connected to the output shaft of the third motor 26. The excess of the solar film 11 after cutting is rolled up and tightened to avoid accumulation at the opening of the cutting box 10.

[0042] In the preferred embodiment, the cut pieces box 10 is an open box at the top, arranged below the far end of the feeding belt 3, and provided with a smooth inclined surface 1001 inside. The finished cut pieces of the solar film 11 fall against the smooth inclined surface 1001 to prevent vertical fall damage.

[0044] When in use, the solar film 11 is set on the feeding roller 7, and passes around the far end of the feeding belt 3, the turning roller 8, and the receiving roller 9 in sequence. The first motor 4 is connected to one end of the rotating shaft 2 to drive the feeding belt 3 to rotate and transport the solar film 11. The two second motors 6 cooperate to drive the laser cutting head 5 to move and cut the solar film 11 on the two-axis slide plane through multiple synchronous belts, synchronous wheels and idler wheels. The feeding belt 3 rotates, and the cut slices of the solar film 11 fall into the cutting box 10. The remaining material is driven by the third motor 26 and is wound up by the receiving roller 9.
