Description

Technical Field

[0001] This utility model relates to the field of pressing machine technology, specifically to a leveling mechanism for a copper clad laminate pressing machine and the pressing machine thereof. Background Technology

[0002] The main equipment used in the preparation of flexible copper clad laminates is a laminator. The formation of double-sided copper clad laminates is achieved by laminating the film together with the upper and lower copper foils using a laminator. When the two laminating steel rollers of the laminator press the substrate, the surface of the substrate can easily be damaged due to extrusion and friction. Therefore, before the substrate enters the laminating steel rollers, the outer surfaces of the upper and lower copper foils are covered with protective material and pressed together. The protective material is then peeled off the copper clad laminate before it is rolled up.

[0003] During the use of the aforementioned laminating machine, warping is prone to occur when the protective material is peeled off the copper-clad laminate. The existing solution to the warping problem is to let it stand to eliminate it slowly. However, this method is inefficient, and when the warping is severe, it cannot be eliminated by standing, thus affecting product quality. Utility Model Content

[0004] One of the purposes of this utility model is to overcome the defects existing in the prior art and provide a leveling mechanism for a copper clad laminate laminating machine, which can quickly eliminate surface warping of copper clad laminates and improve production efficiency.

[0005] To achieve the above-mentioned technical effects, the technical solution of this utility model is as follows: a leveling mechanism for a copper clad laminate laminating machine, characterized in that the leveling mechanism includes a plurality of leveling rollers, the leveling rollers being detachably disposed between two mounting plates; the leveling rollers are connected to the mounting plates via a height adjustment device;

[0006] The vertical direction, the horizontal direction, and the axial direction of the leveling roller are all perpendicular to each other;

[0007] The leveling rollers are staggered vertically along the horizontal direction; the height adjustment device adjusts the height of the leveling rollers along the vertical direction.

[0008] A preferred technical solution is that the height adjustment device includes a guide hole and a locking element. The guide hole is disposed on the mounting plate, and the leveling roller moves up and down along the guide hole and is locked in relative position with the mounting plate by the locking element.

[0009] A preferred technical solution is that the leveling roller includes a shaft and two bearings disposed at both ends of the shaft. The bearings are externally fixedly connected to a mounting base, and the mounting base is provided with a through hole. The locking member passes through the through hole and the guide hole in sequence to connect the leveling roller and the mounting plate.

[0010] A preferred technical solution is that the height adjustment device includes a guide hole and a transmission device, the transmission device being fixedly connected to the leveling roller and driving the leveling roller to move along the guide hole to adjust the height of the leveling roller.

[0011] A preferred technical solution is that the leveling roller includes a shaft and two bearings disposed at both ends of the shaft. The bearings are fixedly connected to mounting seats. The transmission device is fixedly connected to the mounting seats and drives the mounting seats to move up and down in the guide hole.

[0012] The second objective of this utility model is to provide a copper clad laminate laminating machine, including the leveling mechanism for the copper clad laminate laminating machine in the above technical solution, and also including a feeding mechanism, a laminating mechanism, a protective material peeling mechanism and a winding mechanism arranged in sequence.

[0013] The feeding mechanism includes a film feeding roller, copper foil feeding rollers located on the upper and lower sides of the film feeding roller, and protective material feeding rollers located on the upper and lower sides of the copper foil feeding roller.

[0014] The pressing mechanism includes an upper pressing roller and a lower pressing roller, which work together to press the film and copper foil together to form a copper-clad laminate.

[0015] The protective material peeling mechanism includes a protective material peeling roller group for separating the protective material and the copper-clad laminate after being pressed by the pressing mechanism;

[0016] The winding mechanism includes a copper-clad laminate winding roller and a protective material winding roller, and the leveling mechanism is disposed between the protective material peeling mechanism and the copper-clad laminate winding roller;

[0017] A preferred technical solution is that the protective material peeling mechanism includes an upper protective material peeling roller group and a lower protective material peeling roller group, used to separate the upper protective material and the lower protective material sequentially; the protective material winding roller includes an upper protective material winding roller and a lower protective material winding roller, used to wind up the peeled upper and lower protective materials respectively.

[0018] The advantages and beneficial effects of this utility model are as follows: the setting of the leveling mechanism enables the surface of the copper-clad laminate after the protective material is peeled off to be quickly flattened after passing through the leveling mechanism, thus solving the problem of surface warping of the copper-clad laminate.

[0019] With the height adjustment device, the height of the leveling roller in the vertical direction can be adjusted, thereby adjusting the wrap angle of the copper clad laminate with the leveling roller. The leveling capability of the leveling mechanism can be adjusted according to the different degrees of warpage of the copper clad laminate to achieve leveling of the copper clad laminate.

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1-6 As shown in the embodiment, a leveling mechanism for a copper clad laminate laminating machine is provided. The leveling mechanism 1 includes a plurality of leveling rollers 11, which are detachably disposed between two mounting plates 12. The leveling rollers 11 are connected to the mounting plates 12 through a height adjustment device 13.

[0032] The vertical direction, the horizontal direction, and the axis of the leveling roller 11 are all perpendicular to each other;

[0033] The leveling rollers 11 are staggered vertically along the horizontal direction; the height of the leveling rollers 11 is adjusted by the height adjustment device 13 along the vertical direction.

[0034] The leveling mechanism 1 enables the copper-clad laminate surface to be quickly leveled after the protective material is peeled off, thus solving the problem of surface warping of the copper-clad laminate caused by the peeling off of the protective material.

[0035] The 11 adjacent leveling rollers are staggered vertically along the horizontal direction to fully cover and deal with the different warping directions of the copper clad laminate.

[0036] By adjusting the height of the leveling roller 11 in the vertical direction using the height adjustment device 13, the wrap angle between the copper-clad laminate and the leveling roller 11 can be adjusted, resulting in different leveling effects. The position of the leveling roller 11 can be adjusted according to the different degrees of warpage of the copper-clad laminate to achieve better leveling of the copper-clad laminate. Specifically, the wrap angle (referring to the wrap angle between the copper-clad laminate and the leveling roller 11) is related to the contact arc (i.e., the contact surface between the copper-clad laminate and the leveling roller 11). The longer the contact arc, the larger the wrap angle, and vice versa. The larger the wrap angle, the stronger the leveling ability of the leveling roller 11, and vice versa.

[0037] Furthermore, by adjusting the height of the leveling roller 11, the tension of the copper-clad laminate via the leveling roller 11 is adjusted synchronously; different tensions result in different leveling capabilities of the leveling roller 11 on the copper-clad laminate; the greater the tension, the stronger the leveling capability.

[0038] like Figure 1-4As shown, the height adjustment device 13 includes a guide hole 131 and a locking member 132. The guide hole 131 is provided on the mounting plate 12. The leveling roller 11 moves up and down along the guide hole 131 and is locked in relative position with the mounting plate 12 by the locking member 132.

[0039] The leveling roller 11 includes a shaft 111 and two bearings 112 disposed at both ends of the shaft 111. A mounting base 14 is fixedly connected to the bearings 112. A through hole 141 is provided on the mounting base 14. A locking member 132 passes through the through hole 141 and the guide hole 131 in sequence to connect the leveling roller 11 and the mounting plate 12.

[0040] The guide hole 131 restricts the movement direction of the leveling roller 11 to the vertical direction; multiple guide holes 131 are provided, and the number of guide holes 131 is consistent with the number of leveling rollers 11 and corresponds one-to-one with the leveling rollers 11.

[0041] The locking component 132 is used to fix the position of the leveling roller 11 on the guide hole 131 and the mounting plate 12. The locking component 132 includes a bolt and a nut. The bolt passes through the through hole 141 and the guide hole 131 in sequence to connect the leveling roller 11 and the mounting plate 12, and the nut locks the relative position of the leveling roller 11 and the mounting plate 12.

[0042] like Figure 5-6 As shown, in another preferred embodiment, the height adjustment device 13 includes a guide hole 131 and a transmission device 133. The transmission device 133 is fixedly connected to the leveling roller 11 and drives the leveling roller 11 to move along the guide hole 131 to adjust the height of the leveling roller 11.

[0043] The leveling roller 11 includes a shaft 111 and two bearings 112 disposed at both ends of the shaft 111. A mounting base 14 is fixedly connected to the bearing 112. The transmission device 133 is fixedly connected to the mounting base 14 and drives the mounting base 14 to move up and down in the guide hole 131.

[0044] In this embodiment, the transmission device 133 can be a cylinder or a hydraulic cylinder; the transmission device 133 is connected to the leveling roller 11 and causes the leveling roller 11 to move linearly.

[0045] Both ends of the leveling roller 11 are equipped with transmission components. The two transmission components move synchronously and control one leveling roller 11 to move in the vertical direction.

[0046] like Figure 1 As shown, in another embodiment, a copper clad laminate laminating machine includes the leveling mechanism for the copper clad laminate laminating machine in the above embodiment, and also includes a feeding mechanism 2, a laminating mechanism 3, a protective material peeling mechanism 4 and a winding mechanism 5 arranged in sequence.

[0047] The feeding mechanism 2 includes a film feeding roller 21, a copper foil feeding roller 22 located on the upper and lower sides of the film feeding roller 21, and a protective material feeding roller 23 located on the upper and lower sides of the copper foil feeding roller 22.

[0048] The pressing mechanism 3 includes an upper pressing roller 31 and a lower pressing roller 32. The upper pressing roller 31 and the lower pressing roller 32 work together to press the film and copper foil together to form a copper-clad laminate.

[0049] The protective material peeling mechanism 4 includes a protective material peeling roller group for separating the protective material from the copper-clad laminate after being pressed by the pressing mechanism 3;

[0050] The winding mechanism 5 includes a copper-clad laminate winding roller 51 and a protective material winding roller 52, and the leveling mechanism 1 is disposed between the protective material peeling mechanism 4 and the copper-clad laminate winding roller 51.

[0051] like Figure 1 As shown, the protective material peeling mechanism 4 includes an upper protective material peeling roller group 41 and a lower protective material peeling roller group 42, which are used to separate the upper protective material and the lower protective material in sequence; the protective material take-up roller 52 includes an upper protective material take-up roller 52 and a lower protective material take-up roller 52, which are used to take up the peeled upper protective material and the lower protective material respectively.

[0052] In this embodiment, two protective film feeding rollers 21 are respectively disposed below the lower copper foil feeding roller 22 and above the upper copper foil feeding roller 22 to convey the protective material to the pressing mechanism 3.

[0053] In this embodiment, the copper-clad laminate is a double-sided copper-clad laminate formed by laminating an intermediate film and upper and lower copper foils. During lamination, a protective material is provided on the outside of the copper foil and enters the lamination mechanism 3 together to prevent damage to the copper foil during lamination. The protective material passes sequentially through the lamination mechanism 3, the protective material peeling mechanism 4, and the protective material winding roller 52, and is wound up to the protective material winding roller 52. The copper-clad laminate formed by lamination by the lamination mechanism 3 then passes sequentially through the protective material peeling mechanism 4 and the leveling mechanism 1 to the copper-clad laminate winding roller 51 for winding.

[0054] Furthermore, a preheating mechanism is provided between the film feeding roller 21 and the pressing mechanism 3 to facilitate the subsequent pressing of the heated intermediate film with the copper foil.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
