[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, a heating and curing device for a flexible copper-clad laminate comprises a bottom ring 1 and a support frame 13, wherein an annular groove 2 is provided on the upper side of the bottom ring 1, an annular clamping plate 3 is installed on the two side walls of the annular groove 2, a mounting frame 4 is provided on the inner side of the bottom ring 1, a threaded rod 5 is installed on the upper side of the center of the mounting frame 4, a nut 6 is provided on the outer side of the upper part of the threaded rod 5, a positioning plate 7 is installed on the lower edge of the nut 6, a plurality of groups of air guide holes 8 are provided on the positioning plate 7, and a protective cushion 9 is provided on the lower side of the positioning plate 7. When installing the copper plate, the nut 6 and the positioning plate 7 are moved to the upper part of the threaded rod 5, the uncoated side of the copper plate is placed at the lower part, and the uncoated side of the copper plate is placed at the lower part. Insert it into the annular groove 2, and clamp the copper plate through two groups of annular clamps 3. The size of the bottom ring 1 is fixed, and the annular groove 2 on the upper side of the bottom ring 1 is set with multiple sizes. According to the width of the copper plate, select the bottom ring 1 with an annular groove 2 of suitable radius to make the copper plate form an arc structure on the inner side of the annular groove 2, turn the nut 6 downward, and drive the positioning plate 7 to move downward through the nut 6, so that the positioning plate 7 is pressed on the upper side of the copper plate, and the protective soft pad 9 is separated between the copper plate and the positioning plate 7 to protect the copper plate. The side where the two groups of annular clamps 3 are close to each other is made of tough rubber material, and the copper plate is in sealed contact with the two groups of annular clamps 3 to prevent the volatile solvent from contacting the uncoated side of the copper plate and causing oxidation of the uncoated side of the copper plate.

[0023] The support frame 13 is provided with a mounting plate 12 on the upper side, and a plurality of through holes 16 are equidistantly arranged on the mounting plate 12. A plurality of hot air blowers 15 are arranged inside the support frame 13, and the plurality of hot air blowers 15 correspond to the plurality of through holes 16 up and down, respectively. A mounting frame 17 is arranged inside the through hole 16, and a threaded rod 18 is installed at the center of the mounting frame 17. A threaded hole 11 matching with the threaded rod 18 is arranged at the center of the lower side of the mounting frame 14.
