Description

Technical Field

[0002] Dynamic optical film is a thin film material that can change its optical properties according to external stimuli such as light, electricity, heat, humidity, etc. These materials are widely used in smart windows, display technology, optical sensors, automotive industry and other fields. In the process of producing dynamic optical film, cutting the optical film is also an important process. Laser cutting technology is often used to cut optical film because it has the advantages of high cutting size accuracy, no deformation of the cutting seam, fast cutting speed and no restrictions on processing shape.

[0003] However, the existing cutting devices still have certain defects. During the cutting process, the optical film is prone to offset or warping, which directly affects the cutting effect and cutting accuracy of the optical film, resulting in uneven incisions and poor cutting quality. In severe cases, the optical film may be directly damaged, causing certain losses. In addition, if dust and other impurities adhere to the optical film during the cutting process or debris generated during cutting, it will also affect the cutting quality, which is not conducive to actual use.

[0015] Compared with the prior art, the invention has the following advantages: 1. The dynamic optical film is transported by the conveyor belt body so that the cutting position of the dynamic optical film is directly below the laser cutting equipment. The pressing mechanism is then driven downward by the lifting mechanism. The pressing frame and the protective pad are firmly pressed on the dynamic optical film under the action of the elastic force of the buffer spring, so that the dynamic optical film can be well pressed and positioned. At the same time, the side of the dynamic optical film is pressed to prevent the dynamic optical film from displacement, shaking or warping during the cutting process, thereby ensuring the cutting quality.

[0026] The lifting frame 3 is driven up and down by the extension and retraction of the inner rod of the lifting cylinder 31, and the lifting frame 3 drives the clamping mechanism to move up and down. The clamping mechanism moves downward to clamp and position the dynamic optical film.

[0027] See also Figure 4 and Figure 6 A screw rod 37 is rotatably installed in one of the strip slide grooves 32 on the inner side of the lifting frame 3.

[0030] The guide light rod 35 is slidably connected to the lifting frame 3 up and down. The upper and lower ends of the buffer spring 36 are respectively in contact with the lifting frame 3 and the pressing frame 33. The buffer spring 36 applies a downward elastic force to the pressing frame 33.

[0031] When the lifting frame 3 moves downward, it drives the clamping frame 33 to move downward synchronously. When the protective pad 34 at the lower end of the clamping frame 33 contacts the dynamic optical film, the clamping frame 33 cannot continue to move downward. When the lifting frame 3 continues to move downward, the lifting frame 3 slides downward along the guide light rod 35. At the same time, the lifting frame 3 squeezes the buffer spring 36. Under the action of the elastic force of the buffer spring 36, the clamping frame 33 and the protective pad 34 are firmly pressed on the dynamic optical film, so that the dynamic optical film can be well pressed and positioned, and the side of the dynamic optical film can be pressed at the same time to prevent the dynamic optical film from being displaced, shaking or tilting during the cutting process, thereby ensuring the cutting quality.

The inner cavity of the connecting box 44 is connected to the inner cavity of the dust collection box 43. The upper end of the concave seat 4 is symmetrically fixedly installed with L-shaped brackets. The upper ends of the two L-shaped brackets are respectively connected to the two The connecting tubes 45 are fixedly connected and supported by two L-shaped brackets. A dust suction device 47 is fixedly installed on the upper end of the upper top plate 2. The dust suction port of the dust suction device 47 is connected to a hose 46 through a pipe joint.

[0033] The dust collection device 47 generates negative pressure suction in the dust collection box 43 through the hose 46, the connecting pipe 45, and the connecting box 44, so that the debris, dust, etc. on the dynamic optical film are sucked away. The debris, dust, etc. are sucked into the dust collection box 43, and then sucked into the dust collection device 47 along the connecting box 44, the connecting pipe 45, and the hose 46 for collection.

[0039] When the lifting frame 3 moves up and down, the lifting frame 3 drives the L-shaped block 6 to slide up and down along the limiting groove 22, so that the L-shaped block 6 can move stably, and the L-shaped block 6 drives the driving tooth plate 61 to move up and down, and the driving tooth plate 61 drives the gear 73 to rotate, and the gear 73 drives the transmission tooth plate 72 to move up and down, and the transmission tooth plate 72 drives the bearing plate 7 to move up and down. The movement direction of the transmission tooth plate 72 and the bearing plate 7 is opposite to that of the lifting frame 3.

[0040] When the lifting frame 3 moves downward to the lowest end, the pressing frame 33 drives the protection pad 34 to be firmly pressed on the dynamic optical film, and at the same time, the lifting frame 3 drives the lower ends of the roller 53 and the soft brush roller 54 to contact the dynamic optical film; When the lifting frame 3 moves downward, it drives the L-shaped block 6 to move downward, and the L-shaped block 6 drives the driving tooth plate 61 to move downward, and the driving tooth plate 61 drives the gear 73 to rotate, and the gear 73 drives the transmission tooth plate 72 to move upward, and the transmission tooth plate 72 drives the supporting plate 7 to move upward. When the lifting frame 3 moves downward to the lowest end, the upper end of the supporting plate 7 is tightly attached to the upper end of the inner side of the conveyor belt body 11, thereby supporting the conveyor belt body 11. Through the cooperation of the supporting plate 7, the conveyor belt body 11, the clamping frame 33, and the protective pad 34, the dynamic optical film can be firmly clamped and positioned.

[0041] Working principle: The dynamic optical film is transported by the conveyor belt body 11 so that the cutting position of the dynamic optical film is directly below the laser cutting equipment 42, and then the inner rod of the lifting cylinder 31 is extended downward to drive the lifting frame 3 to move downward, and the lifting frame 3 drives the clamping mechanism and the concave seat 4 to move downward synchronously. When the protective pad 34 at the lower end of the clamping frame 33 contacts the dynamic optical film, the lifting frame 3 continues to move downward, so that the lifting frame 3 slides downward along the guide light rod 35, and the lifting frame 3 squeezes the buffer spring 36. Under the action of the elastic force of the buffer spring 36, the clamping frame 33 and the protective pad 34 are firmly pressed on the dynamic optical film, so that the dynamic optical film can be well pressed and positioned, and the side of the dynamic optical film is pressed at the same time to prevent the dynamic optical film from being displaced, shaking or warping during the cutting process, thereby ensuring the cutting quality.

[0043] When the lifting frame 3 moves downward, it drives the L-shaped block 6 to move downward, and the L-shaped block 6 drives the driving tooth plate 61 to move downward, and the driving tooth plate 61 drives the gear 73 to rotate, and the gear 73 drives the transmission tooth plate 72 to move upward, and the transmission tooth plate 72 drives the supporting plate 7 to move upward. When the lifting frame 3 moves downward to the lowest end, the upper end of the supporting plate 7 is tightly attached to the upper end of the inner side of the conveyor belt body 11, thereby supporting the conveyor belt body 11. Through the cooperation of the supporting plate 7, the conveyor belt body 11, the clamping frame 33, and the protective pad 34, the dynamic optical film can be firmly clamped and positioned, so that the laser cutting equipment 42 can accurately cut the dynamic optical film.

[0044] After the cutting of the dynamic optical film is completed, the inner rod of the lifting cylinder 31 is retracted upward to drive the lifting frame 3 to move upward, so that the bearing mechanism is reset downward, and the clamping mechanism and the dust suction mechanism are both moved upward and reset. At this time, the clamping mechanism releases the clamping positioning of the dynamic optical film; the dynamic optical film is then continued to be transported through the conveyor belt body 11, the cut dynamic optical film is transported away, and then the position where the dynamic optical film needs to be cut is transported to the bottom of the laser cutting equipment 42. During the rotation of the conveyor belt body 11, the lower end of the outer side of the conveyor belt body 11 slides along the scraper 14 and the cleaning brush 15. The scraper 14 and the cleaning brush 15 cooperate to clean the dynamic optical film debris, dust, etc. on the conveyor belt body 11 to prevent them from adhering to the conveyor belt body 11 and affecting the subsequent cutting of the dynamic optical film.
