Description

Technical Field

[0001] This utility model relates to the field of copper foil processing technology, and in particular to a copper foil composite heat insulation pressing device. Background Technology

[0002] With the continuous development of technology, the performance requirements for electronic products are becoming increasingly stringent, especially the demand for thin, light, and high-performance electronic products. Copper foil, as an important electronic material, is widely used in the manufacturing of electronic products. Copper foil has excellent conductivity, electromagnetic shielding properties, and high strength, and is widely used in conductive layers, electromagnetic shielding layers, and structural support components of electronic circuits. However, after the copper foil and materials have undergone long-distance displacement on the equipment, their angle may become slightly skewed, which may lead to problems such as misalignment, slippage, and wrinkles in the hot-pressed copper foil. In addition, preheating the copper foil during the conveying process is difficult to achieve a good preheating effect due to the short contact time between the copper foil and the preheating roller, and it is also easy to waste resources.

After the height of the L-shaped plate is adjusted, the front and rear sides of the heat-conducting sleeve can be longitudinally limited. Then, the second servo motor is activated to drive the second threaded rod to rotate and drive the two second threaded sleeves to move backward synchronously. The L-shaped plate can be used to drive the excess heat-conducting sleeve to detach from the preheating roller. Then, when the copper foil comes into contact with the outermost heat-conducting sleeve of the preheating roller, it can be effectively heated. The setting of the steering roller can increase the contact range between the copper foil and the heat-conducting sleeve, thereby improving the preheating effect and thus improving the subsequent pressing efficiency of the copper foil.

[0021] The correction mechanism includes two arc-shaped limiting plates 23, which are inserted into the front and rear sides between the two first guide rollers 3. Two symmetrical traction rods 24 are fixedly connected to the opposite sides of the two arc-shaped limiting plates 23, and the other end of the two traction rods 24 is fixedly connected to the same first threaded sleeve 25. The inner threads of the two first threaded sleeves 25 are set in opposite directions, and the inner threads of the two first threaded sleeves 25 are connected to the same first threaded rod 26. The rear end of the first threaded rod 26 is rotatably connected to the inner wall of the fixed frame 2. A bracket 27 is welded to the front side of the fixed frame 2, and a first servo motor 28 is set on the bracket 27. A bearing is set on the front side of the fixed frame 2, and the front end of the first threaded rod 26 passes through the inner cavity of the bearing and is fixedly connected to the power output end of the first servo motor 28.

[0026] The adjustment mechanism includes several heat-conducting sleeves 31, which are sleeved together on the outer wall of the preheating roller 8. Movable plates 35 are located near the front and rear sides of the bottom of the preheating roller 8, and the tops of the movable plates 35 are mounted on electric telescopic rods 36. L-shaped plates 37 are fixedly connected to the power ends of both electric telescopic rods 36, and the horizontal distance between the two L-shaped plates 37 is the same as the length of the heat-conducting sleeves 31. Vertical rods 38 are slidably connected to both movable plates 35, and the tops of the vertical rods 38 are fixedly connected to the L-shaped plates 37. Second threaded sleeves 39 are fixedly connected to the bottoms of the two movable plates 35, and the internal threads of the two second threaded sleeves 39 are arranged in opposite directions.

A connecting box 34 is inserted and fixed to the rear side of the fixed frame 2, and a second servo motor 41 is provided on the rear side wall of the connecting box 34. The front end of the second threaded rod 40 is rotatably connected to the inner wall of the fixed frame 2, and the rear end of the second threaded rod 40 is fixedly connected to the power output end of the second servo motor 41. The bottom of the two second threaded sleeves 39 are fixedly connected to the slide plate 42, and the same crossbar 32 is slidably connected to the two slide plates 42. The front end of the crossbar 32 is fixedly connected to the inner wall of the fixed frame 2, and the rear end of the crossbar 32 is fixedly connected to the inner wall of the connecting box 34. By controlling the number of heat-conducting sleeves 31 on the preheating roller 8, the preheating temperature of the copper foil can be adjusted. At the same time, the contact range between the copper foil and the preheating roller 8 can be effectively increased, and the preheating effect can be improved.

[0027] Working Principle: In use, this invention first adjusts the horizontal distance between the two arc-shaped limiting plates 23 according to the width of the copper foil. Then, the first servo motor 28 is activated to rotate the first threaded rod 26, causing the two first threaded sleeves 25 to move horizontally. This, in turn, drives the two arc-shaped limiting plates 23 to move horizontally via the traction rod 24, adjusting the horizontal distance between them. When the copper foil passes between the two first guide rollers 3, its front and rear sides are respectively in contact with the adjacent arc-shaped limiting plates 23, thus achieving the purpose of traction and limiting the copper foil. When the copper foil passes through the inner cavity of the first slot 6 and onto the heat-conducting sleeve 31 on the surface of the preheating roller 8, heat is transferred to the heat-conducting sleeve 31 through the preheating roller 8, preheating the copper foil. Furthermore, when temperature control is required during preheating, the electric telescopic rod 36 can be activated to push the L-shaped plate 37 up and down, so that the top of the L-shaped plate 37 is aligned with the plate to be pushed away. The heat-conducting sleeve 31 is attached to the first heating element. Then, the second servo motor 41 is started to drive the second threaded rod 40 to rotate. The rotation of the second threaded rod 40 drives the two second threaded sleeves 39 to move backward synchronously. Thus, the heat-conducting sleeve 31 is pushed backward synchronously by the L-shaped plate 37 and moved to the rear side of the preheating roller 8. When the copper foil comes into contact with the heat-conducting sleeve 31 on the surface of the preheating roller 8, it can be precisely preheated. The copper foil on the surface of the preheating roller 8 can be tensioned by the setting of the steering roller 11. After the copper foil is preheated, it is passed between the lower heating roller 15 and the upper heating roller 16. The lifting plate 18 is pushed vertically downward by the electric rod 17, and the upper heating roller 16 heats and presses the copper foil. The inner cavity of the upper heating roller 16 and the lower heating roller 15 are provided with heat insulation layer to avoid high temperature damage to the copper foil. After the copper foil is pressed, it can be transported out under the traction of the second guide roller 4. The upper and lower surfaces of the copper foil can be cooled and dissipated by the setting of the fan 22.
