[0028] This invention provides a flexible copper-clad laminate laminating device for flexible circuit boards of high-frequency circuits.

[0029] Example 1:

[0030] like Figures 1-4 As shown, it includes a support 1, with an upper pressing roller 2 and a lower pressing roller 3 rotatably connected inside the support 1. Two sets of adjusting components 4 are fixedly connected to the inner walls on both sides of the support 1. A guide roller 5 is rotatably connected between each set of adjusting components 4. The two guide rollers 5 are distributed vertically to guide the PI film and the copper foil film respectively.

[0031] Each adjusting assembly 4 comprises two adjusting seats 41, and the two adjusting seats 41 of each adjusting assembly 4 are fixed on the two sides of the inner wall of the support 1 respectively. A lead screw 42 is rotatably connected in the adjusting seat 41. A sliding seat 43 is threadedly connected to the outer surface of the lead screw 42. The bottom surface of the sliding seat 43 is in abutment with the inner bottom of the adjusting seat 41, so that the sliding seat 43 is prevented from rotating with the lead screw 42 during the rotation of the lead screw 42. A U-shaped seat 431 is fixedly connected to one side of the sliding seat 43. A U-shaped cover 432 is fixedly installed on the top of the U-shaped seat 431. The U-shaped cover 432 is fixedly installed on the top of the U-shaped seat 431 by bolts. Bearings 51 are fixedly installed on the two ends of the guide roller 5 and between the U-shaped seat 431 and the U-shaped cover 432, so that the end of the guide roller 5 is rotatably connected to one side of the sliding seat 43, thereby supporting the guide roller 5. This structure facilitates the disassembly and assembly of the guide roller 5, thereby facilitating the later maintenance. One end of the lead screw 42 is fixedly connected with a worm gear 44. A transmission shaft 45 is rotatably connected in the support 1. Two worm gears 46 are fixedly connected to the outer surface of the transmission shaft 45. The worm gears 46 are engaged with the worm gear 44. During the rotation of the transmission shaft 45, the two worm gears 46 can drive the two worm gears 44 of each adjusting assembly 4 to rotate synchronously, so that the two lead screws 42 of each adjusting assembly 4 rotate synchronously, thereby synchronously adjusting the two ends of the guide roller 5. One end of the transmission shaft 45 penetrates to the outside of the support 1. A handle 47 is fixedly connected to the end of the transmission shaft 45 penetrating to the outside of the support 1, thereby facilitating the rotation of the transmission shaft 45 by the handle 47.

[0032] It should be noted that the worm gear 44 is arranged at one end of the lead screw 42 close to the pressing roller. The transmission shaft 45 of the upper adjusting assembly 4 is located above the worm gear 44 of the upper adjusting assembly 4. The transmission shaft 45 of the lower adjusting assembly 4 is located below the worm gear 44 of the lower adjusting assembly 4. In this way, the transmission shaft 45 will not contact the PI film and the copper foil film when the two guide rollers 5 guide the PI film and the copper foil film.

[0033] As shown in Figure 2 , one end of the upper pressing roller 2 is fixedly connected with a gear one 21. One end of the lower pressing roller 3 is fixedly connected with a gear two 31. The gear one 21 is engaged with the gear two 31. A motor 6 is fixedly installed on one side of the support 1. An output end of the motor 6 is fixedly connected with a main gear 61. The main gear 61 is engaged with the gear two 31. The motor 6 drives the gear two 31 to rotate through the main gear 61. The gear two 31 drives the gear one 21 to rotate, thereby enabling the upper pressing roller 2 and the lower pressing roller 3 to rotate synchronously, achieving the pressing and conveying of the PI film and the copper foil film. One side of the support 1 is fixedly connected with a partition plate 11. The partition plate 11 is located between the handle 47 and the gear, thereby preventing the gear from being touched during the operation of the handle 47.
