A spring 8 is movably sleeved on the outer side of the pin rod 7, and the two ends of the spring 8 are movably abutted against the support frame 2 and the support block 4 respectively.

[0033] The cleaning assembly includes a shovel plate 9 that is movably abutted against the outer side of the hot pressing roller 1, and the shovel plate 9 is in an inclined state. The end of the shovel plate 9 away from the hot pressing roller 1 is fixedly connected to a fixed shaft 10. A U-shaped groove 11 is provided on the support block 4 corresponding to the fixed shaft 10, and the fixed shaft 10 is movably plugged into the support block 4 through the U-shaped groove 11. Two symmetrically distributed baffles 12 are movably fitted to the outer side of the support block 4, and the surface of the baffle 12 away from the support block 4 is flush with the surface of the support frame 2.

[0034] The connection between the baffle 12 and the support frame 2 is a fixed connection. The baffle 12 is close to the two support blocks 4 and is away from each other at one end. A movable groove 13 is provided on the baffle 12, and the fixed shaft 10 is in sliding contact with the baffle 12 through the movable groove 13.

[0035] The adjusting assembly includes an adjusting screw 21 rotatably connected to the support frame 2 through a bearing, and the adjusting screw 21 is located at the center of the support frame 2, a baffle 22 is fixedly connected to the lower end of the adjusting screw 21, and the baffle 22 is located on the lower side of the support frame 2, and a pin block 23 is threadedly sleeved on the outer side of the adjusting screw 21, and the baffle 22 is used to prevent the pin block 23 from detaching from the adjusting screw 21, and the pin block 23 can move up and down inside the support frame 2.

[0036] A plurality of ball rollers 24 are movably embedded on the outer side of the pin block 23, and the connection between the ball rollers 24 and the support frame 2 is rolling contact. Beveled edges are provided on both sides of the pin block 23, and ball rollers 3 25 are movably abutted at the beveled edges of the pin block 23, and ball rollers 3 25 are movably embedded in the interior of the support block 4.

[0037] Working principle: Two motors 3 drive two hot pressing rollers 1 to rotate in different directions respectively. The copper foil and the substrate are located between the two hot pressing rollers 1. Driven by the compression force of the spring 8, the two hot pressing rollers 1 can squeeze the copper foil and the substrate, so that during the rotation of the two hot pressing rollers, the adhesive on the substrate can be heated and the copper foil and the substrate can be pressed together. During this process, part of the adhesive on the pressed edge of the copper clad laminate will overflow and adhere to the hot pressing roller 1.

[0038] Since the scraper plate 9 is movably fitted with the hot pressing roller 1, the scraper plate 9 can scrape off the adhesive adhered to the hot pressing roller 1 during the rotation of the hot pressing roller 1, thereby preventing the adhesive adhered to the hot pressing roller 1 from adhering to the surface of the pressed copper clad laminate during the rotation of the hot pressing roller 1 and affecting the quality of the copper clad laminate.

[0039] Example 2: Please refer to Figure 8 , this embodiment further explains the first embodiment, the pressing assembly includes a support plate 15 whose two ends are fixedly connected to the two support blocks 4 respectively, and a plurality of inclined sleeves 16 distributed at equal distances are fixedly installed on the upper end of the support plate 15, and a push rod 17 is movably embedded in the end of the inclined sleeve 16 away from the support plate 15, and a ball 18 is movably embedded in the end of the push rod 17 close to the shovel plate 9, and the connection between the ball 18 and the shovel plate 9 is a rolling contact, and the ball 18 can reduce the friction resistance between the push rod 17 and the shovel plate 9, and a gasket 19 is fixedly connected to the end of the push rod 17 away from the ball 18, and the gasket 19 is located inside the inclined sleeve 16, and a spring 20 is movably abutted on the side of the gasket 19 away from the push rod 17, and the end of the spring 20 away from the gasket 19 is movably abutted against the inclined sleeve 16.

[0040] In the present embodiment: during the rotation of the hot pressing roller 1, since the hardness of the scraper plate 9 is less than that of the hot pressing roller 1, the scraper plate 9 is in contact with the rotating hot pressing roller 1 for a long time, which will cause wear on the edge of the scraper plate 9. During this process, a plurality of push rods 17 are driven by the compression force of the spring 20 to press against the scraper plate 9 through the ball 18, which helps to keep the scraper plate 9 and the hot pressing roller 1 in contact at all times, and can effectively avoid the wear of the scraper plate 9 resulting in a gap between the scraper plate 9 and the hot pressing roller 1, affecting the scraping effect of the scraper plate 9 on the hot pressing roller 1.

[0041] Example 3: Please refer to Figure 7 , Figure 8This embodiment further explains the second embodiment. A driving assembly is installed on the lower side of the pressing assembly. The driving assembly includes a pull rope 26 movably embedded in the center of the gasket 19, and the pull rope 26 is located on the side of the gasket 19 away from the top rod 17. A bent conduit 27 is movably sleeved on the outer side of the pull rope 26, and the bent conduit 27 passes through the support plate 15 and the inclined sleeve 16 respectively. The bent conduit 27 is used to reduce the friction resistance between the pull rope 26 and the support plate 15 and the inclined sleeve 16. The connection between the top rod 17 and the support plate 15 is a fixed connection.

[0042] The lower end of the pull rope 26 is fixedly connected to a slide rod 28, and the cross-sectional shape of the slide rod 28 is circular. A limiting straight groove 29 is provided on the support frame 2 corresponding to the slide rod 28, and the slide rod 28 is slidably connected to the support frame 2 through the limiting straight groove 29. The limiting straight groove 29 is used to limit the moving distance of the slide rod 28. Two symmetrically distributed guide rods 30 are fixedly installed on the outer side of the lower end of the support plate 15 corresponding to the pull rope 26, and the cross-sectional shape of the lower end of the guide rod 30 is semicircular, and the connection between the pull rope 26 and the guide rod 30 is sliding contact.

[0043] In this embodiment: a person rotates the two adjusting screws 21, and the adjusting screws 21 rotate to drive the pin block 23 to move upward inside the support frame 2. During the upward movement of the pin block 23, the two support blocks 4 and the two hot pressing rollers 1 are driven to move away from each other through the bevel portion and the ball bearing 3 25. During this process, the slide bar 28 will move with the support plate 15 inside the limiting straight groove 29 (the length of the limiting straight groove 29 is the thickness range of the copper clad plate that the hot pressing roller 1 can press, and the slide bar 28 will not affect the push rod 17 during the movement inside the limiting straight groove 29). When the movement of the slide bar 28 is blocked by the limiting straight groove 29, the support block 4 and When the support plate 15 continues to move, the slide bar 28 will drive the push rod 17 to move into the inclined sleeve 16 through the pull rope 26, and the shovel plate 9 will rotate away from the hot pressing roller 1 under the action of gravity. When the support block 4 moves to the maximum value, the upper end of the U-shaped embedding groove 11 and the movable groove 13 will be aligned with the lower end of the notch groove 14, so that the fixed shaft 10 of the shovel plate 9 can be removed from the support block 4. When installing a new shovel plate 9, since the multiple push rods 17 shrink into the interior of the inclined sleeve 16, a large distance is left between the multiple push rods 17 and the hot pressing roller 1. Therefore, when installing the shovel plate 9, the multiple push rods 17 will not block the shovel plate 9.

[0044] At the same time, when the distance between the two support blocks 4 and the two hot pressing rollers 1 reaches the maximum value, personnel can easily place the substrate and the copper foil between the two hot pressing rollers 1. After the shovel plate 9 is replaced or the substrate and the copper foil are discharged, the adjusting screw 21 is rotated to drive the pin block 23 to move downward. The two adjacent support blocks 4 will approach each other under the drive of the compression elastic force of the spring 8, and the fixed axis 10 of the shovel plate 9 will move in the horizontal part of the movable groove 13 under the drive of the support block 4. At this time, the fixed axis 10 can be positioned through the U-shaped groove 11 of the support block 4 and the horizontal part of the movable groove 13, so that the fixed axis 10 can rotate but cannot move.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
