Technical Field
[0001] The utility model relates to the technical field of copper clad laminate production and processing equipment, in particular to a copper clad laminate pressing machine and a heating device thereof. Background Art
[0002] Copper-clad laminates (CCLs) are manufactured by first impregnating electronic fiberglass cloth or other reinforcing materials with resin to form a prepreg. Copper foil is then applied to one or both sides of the prepreg and hot-pressed. To ensure product quality, CCL pressing machines typically require vacuuming and hot-pressing under near-vacuum conditions. Therefore, during hot pressing, the sheets are heated primarily by heat conduction.
[0003] The heating device heats the plate by heat conduction, which requires contact with the plate. However, existing heating devices are often rigid and inflexible, and can usually only heat plates of fixed sizes, with a narrow range of applications. Summary of the Invention

[0029] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.
[0030] The following is combined with Figure 1 ~Attached Figure 5 The embodiments of the present utility model are described in detail.
[0031] An embodiment of the present invention provides a heating device. The heating device includes: a heat exchange chamber 1, a first guide rail 2 that limits the heat exchange chamber 1, a first power source 3 that drives the heat exchange chamber 1 to move along the first guide rail 2, a second guide rail 4 that limits the first guide rail 2, and a second power source 5 that drives the first guide rail 2 to move along the second guide rail 4. The first guide rail 2 extends in the front-to-back direction and is provided in two parallel lines in the left-to-right direction. Two heat exchange chambers 1 are provided in the front-to-back direction for each first guide rail 2. The cross-section of the heat exchange chamber 1 in the horizontal direction is L-shaped, so that the four heat exchange chambers 1 respectively limit the four corners of the plate. It should be understood that the heat exchange chamber 1 heats the plate by contacting with the edge of the plate; usually, a group of plates that need to be pressed together will be separated from another adjacent group of plates by a steel plate, and the steel plate will also serve as a support to keep the plates flat after pressing; the edge of the steel plate will also contact the heat exchange chamber 1, thereby conducting heat to the plate. The plate here refers to a prepreg, copper clad plate or copper foil. The second guide rails 4 extend in the left-right direction, and are provided in two parallel lines in the front-back direction to limit the front and rear ends of the first guide rail 2 respectively.
[0032] The following describes a specific embodiment of the heating device: This heating device is typically used in conjunction with a hydraulic system. It can be used to heat and press stacked prepregs and copper foil to produce copper-clad laminates. It can also be used to heat and press stacked copper-clad laminates and prepregs to further process the copper-clad laminates into composite boards. Heat transfer oil flows within the heat exchange chambers 1, and the area between the four heat exchange chambers 1 constitutes a heating zone. Stacked sheets are placed in the heating zone to heat the sheets. A first power source 3 drives the heat exchange chambers 1 forward and backward along the first guide rails 2, adjusting the distance between the heat exchange chambers 1 in the front-to-back direction. A second power source 5 drives the first guide rails 2 and the heat exchange chambers 1 left and right along the second guide rails 4, adjusting the distance between the heat exchange chambers 1 in the left-to-right direction. This allows for flexible adjustment of the front-to-back and left-to-right lengths of the heating zone. This heating device allows for flexible adjustment of the position of the heat exchange chambers 1 to accommodate heating sheets of varying sizes, thus facilitating the production or processing of copper-clad laminates of varying sizes, offering a wider range of applications.
[0033] Furthermore, the heat exchange chamber 1 is provided with a first wheel frame 6 extending in the front-to-back direction, and a plurality of first rollers 7 are installed along the length direction of the first wheel frame 6 ; the heat exchange chamber 1 is limited to the first guide rail 2 by the first rollers 7 .
[0034] Furthermore, the first power source 3 is a first servo motor that drives the first roller 7 to rotate. It should be understood that the housing of the first servo motor may be covered with a heat-insulating material to reduce the operating temperature of the first servo motor. By driving one of the first rollers 7 of the heat exchange chamber 1 to rotate, the first servo motor can move the heat exchange chamber 1 along the first guide rail 2.
[0035] Furthermore, the front and rear ends of the first guide rail 2 are respectively provided with second wheel frames 8 extending in the left and right directions, and a plurality of second rollers 9 are installed along the length direction of the second wheel frames 8; the front and rear ends of the first guide rail 2 are each limited to the second guide rail 4 by the corresponding second rollers 9.
[0036] Furthermore, the second power source 5 is a second servo motor that drives the second roller 9 to rotate. The second servo motor is a dual-axis motor that is transmission-connected to the second rollers 9 at the front and rear ends of the first guide rail 2. It should be understood that the housing of the second servo motor may be covered with a heat-insulating material to reduce its operating temperature.
[0037] Furthermore, it also includes: a base, a third power source 10 that drives the base to move up and down, and a limit plate 11 that is detachably mounted on the top of the base; the limit plate 11 is provided with four limit openings 12; the limit openings 12 correspond one-to-one to the heat exchange chamber 1 to limit the lower part of the heat exchange chamber 1. It should be understood that the third power source 10 is usually configured as a hydraulic cylinder. By limiting the lower part of the heat exchange chamber 1 through the limit plate 11, the heat exchange chamber 1 can heat the plate more stably and reliably. The third power source 10 drives the base to move downward with the limit plate 11, so that the limit plate 11 is separated from the heat exchange chamber 1, and the plate can be taken and placed on the limit plate 11. After adjusting the position of the heat exchange chamber 1, a new matching limit plate 11 needs to be replaced accordingly.
[0038] Furthermore, the base is provided with a plurality of mounting holes; the limiting plate 11 is provided with countersunk holes corresponding to the mounting holes and is connected to the base via bolts installed in the countersunk holes. It should be understood that this ensures that the upper surface of the limiting plate 11 is flat and free of protrusions.
[0039] Furthermore, a first partition 13 and a second partition 14 are alternately arranged in the heat exchange chamber 1; the first partition 13 extends downward from the top of the heat exchange chamber 1, and a first gap is provided between the bottom of the heat exchange chamber 1 and the first partition 13; the second partition 14 extends upward from the bottom of the heat exchange chamber 1, and a second gap is provided between the top of the heat exchange chamber 1 and the second partition 14; the first partition 13 cooperates with the second partition 14 to change the space in the heat exchange chamber 1 into a winding flow channel.
[0040] Furthermore, the liquid inlet 15 and the liquid outlet 16 of the heat exchange chamber 1 are both arranged at the top.
[0041] The present invention also provides a copper clad laminate press having the aforementioned heating device. It should be understood that the copper clad laminate press may be provided with an upper die driven by a hydraulic cylinder above the heating zone to cooperate with the base to press the plate.
[0042] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
