[0029] The present invention discloses a roll-to-roll small coating device. Figure 1-9 As shown, it includes a base 1, an unwinding assembly 2, a coating assembly 3, a baking assembly 4, a laminating assembly 5, a deviation correcting assembly 6 and a winding assembly 7 which are sequentially arranged on the base 1.

[0030] The unwinding assembly 2 is used to hold the substrate 8. Specifically, it comprises an unwinding frame 21 fixed to the base 1, an unwinding air-inflating shaft 22 positioned on the unwinding frame 21 along the width of the substrate 8, and a plurality of rollers 23. The ends of the unwinding air-inflating shaft 22 are rotatably supported on the side walls of the unwinding frame. The substrate 8 is wound into a roll and mounted on the unwinding air-inflating shaft 22, which then winds around the plurality of rollers 23. Furthermore, to facilitate the replacement of substrate 8 rolls, slots 24 are provided on both sides of the top of the unwinding frame 21. The ends of the unwinding air-inflating shaft 22 are placed in these slots. When the substrate 8 is exhausted, the operator simply removes the unwinding air-inflating shaft 22 and then rolls a new substrate 8 onto it, making it quick and convenient. The unwinding system uses an adjustable knob to adjust the tension of the substrate 8.

[0031] The coating assembly 3 is used to coat the substrate 8. Specifically, the coating assembly 3 includes a coating frame 31 fixed on the base 1, a guide roller 32, a back roller 33, a scraper 34 and a baffle 35 arranged on the coating frame 31. The guide roller 32 and the back roller 33 are rotatably carried on the coating frame 31. The guide roller 32 and the back roller 33 are arranged along the width direction of the substrate 8. The substrate 8 is arranged around the guide roller 32, and the substrate 8 passes between the baffle 35 and the scraper 34 after passing around the guide roller 32. Then, the substrate 8 passes between the back roller 33 and the scraper 34. The baffle 35 is pressed against the substrate 8. The upper surface of the baffle 35 is used to place glue for coating. When the substrate 8 moves, the glue on the baffle 35 is coated on the surface of the substrate 8, and after the substrate 8 passes between the scraper 34 and the back roller 33, the scraper 34 evenly spreads the glue. In addition, the coating frame 31 is provided with supporting blocks 36 on opposite sides. The scraper 34 is connected to the two supporting blocks 36 on either side. A lifting cylinder 37 is fixedly mounted vertically on the coating frame 31. The piston rod of the lifting cylinder 37 is fixedly connected to the supporting blocks 36. The lifting cylinder 37 drives the scraper 34 toward or away from the backing roller 33. When the piston rod of the lifting cylinder 37 extends, the scraper 34 is pressed against the backing roller 33, thereby pressing the substrate 8. Furthermore, the baffle 35 is provided with a limit block 351. The glue is placed between the two limit blocks 351. One side of the limit block 351 abuts the surface of the substrate 8. The operator can adjust the position of the two limit blocks 351 to adjust the range of glue coating, which is convenient and quick. Furthermore, the coating frame 31 is provided with a tray 38. The tray 38 is located below the baffle 35 and the scraper 34. The tray 38 prevents the glue from falling and contaminating the environment. In addition, an electric heating block is provided in the scraper 34 , and the electric heating block can heat the scraper 34 when powered on, thereby adapting to different coating processes.

[0032] The baking assembly 4 is used to bake the coated substrate 8. Specifically, the baking assembly 4 includes an oven 41 fixedly mounted on the base 1. The oven 41 is provided with a heating wire and the like. The oven 41 is provided with a through-hole 42. After the substrate 8 enters the oven 41 through the inlet and outlet 42, the glue on the substrate 8 is dried and then the substrate 8 exits the oven 41 through the inlet and outlet 42. In addition, the oven 41 is provided with an exhaust fan that can quickly exhaust the humid air inside the oven 41.

[0033] The laminating assembly 5 is used to adhere a laminating film to the baked substrate 8. Specifically, the laminating assembly 5 includes a laminating frame 51 fixed to the base 1, a laminating air-expansion shaft 52 positioned on the laminating frame 51 along the width of the substrate 8, a guide roller 53, a bottom roller 54, and a pressing roller 55. The laminating air-expansion shaft 52 is mounted on the laminating frame 51 in the same manner as the unloading air-expansion shaft 22 is mounted on the unloading frame, facilitating replacement of the laminating film. The laminating film is wound into a roll and sleeved on the laminating air-expansion shaft 52. The laminating film is then wrapped around the guide roller 53. The laminating film and the substrate 8 then pass between the bottom roller 54 and the pressing roller 55. At the same time, pressing seats 56 are provided on the opposite sides of the laminating frame 51, and the two ends of the pressing roller 55 are respectively rotatably supported on the pressing seats 56. A pressing cylinder 57 is provided on the laminating frame 51 in the vertical direction, and the piston rod of the pressing cylinder 57 is fixedly connected to the pressing seat 56. The pressing cylinder 57 drives the pressing roller 55 to move in the direction of approaching or moving away from the bottom roller 54. The piston rod of the pressing cylinder 57 is extended, driving the pressing roller 55 to press tightly on the bottom roller 54, thereby pressing the laminating film and the substrate 8 together, thereby protecting the glue layer coated on the substrate 8.

[0034] The correcting assembly 6 is used to correct the position of the substrate 8. Specifically, the correcting assembly 6 includes a mounting frame 61 that is slidably arranged on the base 1 along the width direction of the substrate 8, a correcting roller 62 arranged on the mounting frame 61, a correcting motor 63 arranged on the base 1, and a screw rod 631 coaxially connected to the correcting motor 63. The screw rod 631 is threadedly connected to the mounting frame 61, and the substrate 8 is wound around the correcting roller 62. After the substrate 8 is covered with the laminating film, it passes around the correcting roller 62. When there is an inaccurate alignment between the substrate 8 and the laminating film, the correcting motor 63 is started. The correcting motor 63 works to drive the screw rod 631 to rotate, thereby driving the mounting frame 61 to slide, thereby adjusting the position of the substrate 8 and the composite film, so that the substrate 8 is aligned with the composite film.

[0035] The winding assembly 7 is used to store the substrate 8. Specifically, the winding assembly 7 includes a receiving air-expanding shaft 71 that is rotatably mounted on the mounting frame 61 and a receiving motor 72 that is fixedly mounted on the mounting frame 61. The output shaft of the receiving motor 72 is coaxially connected to the end of the receiving air-expanding shaft 71. The receiving motor 72 drives the receiving air-expanding shaft 71 to rotate, and the receiving air-expanding shaft 71 can wind up the substrate 8. The way the receiving air-expanding shaft 71 is mounted on the mounting frame 61 is consistent with the way the unloading air-expanding shaft 22 is mounted on the unloading frame. In this way, after the substrate 8 is wound to a certain size, the operator can conveniently remove the coated substrate 8. In addition, a square block is provided at the end of the receiving air-expanding shaft 71, and a square slot is provided on the output shaft of the receiving motor 72. The square block is plugged into the square slot, so that the receiving motor 72 can drive the receiving air-expanding shaft 71 to rotate and the receiving air-expanding shaft 71 can be easily removed.

[0036] The implementation principle of a roll-to-roll small coating device in an embodiment of the present invention is as follows: the receiving motor 72 works to drive the substrate 8 to be discharged from the discharge air-inflating shaft 22. When the substrate 8 passes through the baffle 35, the glue on the baffle 35 is coated on the substrate 8, and then the scraper 34 evenly spreads the glue on the substrate 8. Then the substrate 8 passes through the oven 41 to dry the glue, and then a laminating film is laminated on the glue of the substrate 8, and finally it is wound onto the receiving air-inflating shaft 71 to complete the coating of the substrate 8. The entire coating device is small in size, compact in structure, and simple in process, and has lower cost for proofing or small batch production.
