[0051] During the laminating operation, multiple scrapers 193 can be driven to move synchronously to scrape off the glue squeezed to the outside of the two metal copper plates.
[0052] Working principle: When using this processing method to remove burrs from the hole after drilling, Figure 1-6 In the preparation of the copper foil layer, two metal copper plates are placed on the upper adsorption plate 7 and the lower adsorption plate 15 respectively, and the metal copper plates are fixed by the vacuum pump 17 in cooperation with the adsorption hole 151. The metal copper plate on the top of the lower adsorption plate 15 is installed by inserting it into the bottom of the glue coating plate 186. After the installation is completed, the motor 3 on the bracket 2 is started. The motor 3 drives the first movable sleeve 5 to move downward through the rotation of the first screw 4, and then drives the mounting plate 6 and the upper adsorption plate 7 to move downward. The mounting plate 6 drives the positioning sleeve 8 to slide on the positioning rod 9 to realize the positioning movement of the mounting plate 6. At the same time, the motor 3 drives the guide shaft 10 to rotate, and the guide shaft 10 drives the second screw 11 to rotate. Under the action of the positioning telescopic rod 16, the second screw 11 drives the second movable sleeve 12 to move upward. The second movable sleeve 12 drives the telescopic sleeve 14 to move upward through the spring 13, and then can drive the lower adsorption plate 15 to move upward, so as to realize the opposite movement of the two metal copper plates.
[0053] At the same time, the electromagnet 183 is turned off, and the gravity block 182 is no longer adsorbed. The gravity block 182 pushes the glue in the storage box 181 into the glue coating plate 186, and the top sealing plate 1810 rotates counterclockwise, so that the glue passes through the opening of the glue coating plate 186 to reach the metal copper plate below. At the same time, when the lower adsorption plate 15 moves up, it can contact the support head 189 and push the glue coating plate 186. The glue coating plate 186 drives the positioning plate 185 to move up, so that the elastic telescopic rod 184 contracts, and the rotation of the guide shaft 10 can The meshing of the gear 188 and the first rack 187 drives the glue-coating plate 186 to move rightward laterally, so that the glue-coating plate 186 slides within the positioning plate 185, thereby realizing that the glue-coating plate 186 follows the upward movement and moves laterally synchronously, and performs the glue-coating operation on the metal copper plate on the lower adsorption plate 15, until the glue-coating plate 186 leaves the upper part of the lower adsorption plate 15, at which time the electromagnet 183 is started to fix the position of the gravity block 182, and the pressure at the sealing plate 1810 is reduced and rotated to reset, so that the glue is no longer squeezed out;
[0054] Then the upper adsorption plate 7 and the lower adsorption plate 15 continue to move to extrude and stick the upper and lower metal copper plates. During the extrusion, the lower adsorption plate 15 and the telescopic sleeve 14 can slide elastically on the second movable sleeve 12 through the spring 13. At the same time, the guide gear roller 195 in the positioning sleeve 8 moves to the second rack 196 for meshing and rotation. The guide gear roller 195 drives one of the third screws 192 to rotate in the movable groove 191. The four third screws 192 rotate synchronously through the bevel gear roller 194 at the same time, realizing the synchronous movement of the four scraping strips 193. The four scraping strips 193 are used to scrape the four edges of the metal copper plate to scrape off the squeezed glue, and then the motor 3 is driven in reverse, and the vacuum pump 17 is stopped, so that the upper adsorption plate 7 and the lower adsorption plate 15 are separated and reset, and the glue coating plate 186 is reset at the same time, which is convenient for the next operation. During this process, the electromagnet 183 maintains the adsorption of the gravity block 182 to prevent the glue from overflowing.
