[0022] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown, the utility model discloses a winding and unwinding device for a copper clad laminate pressing machine, comprising a base body 1, wherein the base body 1 is connected with a supporting guide wheel 2, a pressure sensing guide wheel 3, a cloth clamping wheel 4, and a winding wheel 5, wherein the supporting guide wheel 2 comprises a first supporting wheel 21 and a second supporting wheel 22, the pressure sensing guide wheel 3 comprises a first pressure sensing wheel 31 and a second pressure sensing wheel 32, the cloth clamping wheel 4 comprises a first cloth clamping wheel 41 and a second cloth clamping wheel 42, and the winding wheel 5 comprises a first winding wheel 51 and a second winding wheel 52, wherein the first supporting wheel 21, the first pressure sensing wheel 31, the first cloth clamping wheel 41, and the first winding wheel 51 can allow a flexible copper clad laminate to pass through in sequence, and the second supporting wheel 22, the second pressure sensing wheel 32, the second cloth clamping wheel 42, and the second winding wheel 52 can allow another flexible copper clad laminate to pass through in sequence.

[0024] The winding device is used to roll up the flexible copper clad laminate after the copper foil and the substrate are introduced into the lamination area and the lamination is completed. The support guide wheel 2 can guide the unfolding or winding of the copper clad laminate to ensure that the material moves smoothly along the predetermined path. The pressure sensing guide wheel 3 is used to detect and control the tension of the copper clad laminate to ensure proper stretching of the material during the transmission process. The cloth clamping wheel 4 can help control the tension of the copper clad laminate while protecting the surface of the material from damage. The winding wheel 5 is used to wind up the copper clad laminate that has been pressed to ensure the flatness and tightness of the copper clad laminate during the winding process. Compared with controlling the tension of the flexible copper clad laminate during the winding process only by the pressure regulating wheel, the coordinated setting of the support guide wheel 2, the pressure sensing guide wheel 3, and the cloth clamping wheel 4 can reduce material damage caused by improper tension.

[0025] The first support wheel 21, the first pressure sensing wheel 31, the first cloth clamping wheel 41, and the first take-up wheel 51 can allow a flexible copper-clad laminate to pass through in sequence, and the second support wheel 22, the second pressure sensing wheel 32, the second cloth clamping wheel 42, and the second take-up wheel 52 can allow another flexible copper-clad laminate to pass through in sequence, so that the laminating machine can process two flexible copper-clad laminates in parallel, thereby improving the production efficiency of a single laminating machine.

[0026] The first support wheel 21, the first pressure sensing wheel 31, the first cloth clamping wheel 41, and the first take-up wheel 51 are arranged on the upper part of the base body 1, and the second support wheel 22, the second pressure sensing wheel 32, the second cloth clamping wheel 42, and the second take-up wheel 52 are arranged on the lower part of the base body 1.

[0027] By arranging the first support wheel 21, the first pressure sensing wheel 31, the first cloth clamping wheel 41, and the first winding wheel 51 on the upper part of the base body 1, and the second support wheel 22, the second pressure sensing wheel 32, the second cloth clamping wheel 42, and the second winding wheel 52 on the lower part of the base body 1, the transmission paths of the two copper clad laminates are clear and independent, avoiding cross interference and improving production efficiency and safety.

[0028] The seat body 1 has a first installation area 11 for installing the supporting guide wheel 2, a second installation area 12 for installing the pressure sensing guide wheel 3, a third installation area 13 for installing the cloth clamping wheel 4, and a fourth installation area 14 for installing the take-up wheel 5. The first installation area 11, the second installation area 12, the third installation area 13, and the fourth installation area 14 are each provided with at least two installation grooves 15. The number of the installation grooves 15 in the first installation area 11 is greater than the number of the supporting guide wheel 2, the number of the installation grooves 15 in the second installation area 12 is greater than the number of the pressure sensing guide wheel 3, the number of the installation grooves 15 in the third installation area 13 is greater than the number of the cloth clamping wheel 4, and the number of the installation grooves 15 in the fourth installation area 14 is greater than the number of the take-up wheel 5.

[0029] Most existing devices have a fixed reeling and unwinding distance, which means that regardless of the width of the copper clad laminate, tension control and material alignment during the reeling and unwinding process may be affected, especially when processing copper clad laminates of different sizes. Since the reeling distance is not adjustable, when processing narrow materials, an excessively long reeling path may be used in order to maintain sufficient tension. At the same time, a fixed reeling path may not be suitable for all types of materials, especially when processing copper foils of different thicknesses or elasticities, which may result in uneven reeling and affect the quality of subsequent processing.

[0030] By setting that the number of mounting grooves 15 in the first mounting area 11 is greater than the number of supporting guide wheels 2, the number of mounting grooves 15 in the second mounting area 12 is greater than the number of pressure sensing guide wheels 3, the number of mounting grooves 15 in the third mounting area 13 is greater than the number of cloth clamping wheels 4, and the number of mounting grooves 15 in the fourth mounting area 14 is greater than the number of winding wheels 5, the number, horizontal height and position of related components can be easily adjusted through the reserved mounting grooves 15, thereby changing the reeling and unreeling distance of the device.

[0031] On this basis, adjusting the position of the support guide wheel 2 can ensure the stability and linearity of the copper clad laminate during the transmission process, and adjusting the position of the pressure sensing guide wheel 3 can optimize the distribution of tension sensing points and improve the accuracy and coverage of tension control. Adjusting the position of the cloth clamping wheel 4 can adapt to copper clad laminates of different materials and thicknesses, while ensuring that the copper clad laminate is stable and undamaged during the transmission process. Adjusting the position of the winding wheel 5 can optimize the winding quality and tightness of the copper clad laminate.

[0032] The mounting grooves 15 are symmetrically arranged along the seat body 1 in an up-and-down manner.

[0033] The symmetrically arranged mounting grooves ensure that the components at the upper and lower parts of the seat body 1 can obtain the same supporting strength and position adjustment capability.

[0034] The guide rail assembly 9 is detachably connected to the mounting groove 15, and the guide rail assembly 9 includes a guide rail 91 and a sliding member 92 that can slide along the guide rail 91. The sliding member 92 can be detachably connected to at least one of the supporting guide wheel 2, the pressure sensing guide wheel 3, the cloth clamping wheel 4, and the winding wheel 5. A threaded fastener 93 that can limit the sliding member 92 from sliding on the guide rail 91 is also provided between the guide rail 91 and the sliding member 92.

[0035] The guide rail 91 allows the slide 92 to slide freely thereon, so that the position of the support guide wheel 2, the pressure sensing guide wheel 3, the cloth clamping wheel 4 or the winding wheel 5 connected to the slide 92 can be finely adjusted to adapt to copper clad laminates of different specifications or optimize the production process. The user can install the guide rail assembly 9 on the installation groove 15 to further adjust the number, horizontal height and position of the relevant components on the relevant guide rail 91 to achieve the purpose of fine adjustment.

[0036] In the embodiment, the position, quantity and size of the installation slots 15 can be set according to the operation requirements.

[0037] The base body 1 is connected to an edge device 6 capable of limiting the deviation of the copper clad laminate. The base body 1 also has a fifth installation area 16 for installing the edge device 6. The fifth installation area 16 is provided with installation grooves 15, and the number of installation grooves 15 in the fifth installation area 16 is greater than the number of edge devices 6.

[0038] The edge alignment device 6 can ensure that the copper clad laminate maintains the correct lateral position during the transmission process, avoiding lamination quality problems caused by offset. By setting the number of mounting slots 15 in the fifth mounting area 16 to be greater than the number of edge alignment devices 6, the number, horizontal height and position of the edge alignment devices 6 can be easily adjusted.

[0039] The fifth installation area 16 is disposed between the second installation area 12 and the third installation area 13 .

[0040] By arranging the fifth installation area 16 between the second installation area 12 and the third installation area 13, the edge alignment device 6 is installed between the pressure sensing guide wheel 3 and the cloth clamping wheel 4, so that the precise guidance of the copper clad laminate can be ensured before and after these two key steps.

[0041] The first support wheel 21 is arranged in parallel with the second support wheel 22, the first pressure sensing wheel 31 is arranged in parallel with the second pressure sensing wheel 32, the first cloth clamping wheel 41 is arranged in parallel with the second cloth clamping wheel 42, and the first winding wheel 51 is arranged in parallel with the second winding wheel 52.

[0042] The parallel arrangement of the components ensures that the upper and lower copper clad laminates can be supported, pressure-sensed, clamped and rolled at the same time, ensuring that the conditions of the upper and lower copper clad laminates are as consistent as possible during the transmission process, achieving dual-channel synchronous production and improving production efficiency.

[0043] A first cloth clamping rod 71 is disposed above the first cloth clamping wheel 41 , and a second cloth clamping rod 72 is disposed below the second cloth clamping wheel 42 .

[0044] The cloth clamping rod and the cloth clamping wheel 4 can be used together to provide additional support points, help control the tension of the copper clad laminate during transportation, ensure the flatness of the copper clad laminate, and avoid wrinkles or relaxation during transportation before and after lamination.

[0045] The base body 1 is also provided with a numerical control panel 8 .

[0046] In the embodiment, the tension of the CNC panel 8 can be adjusted accurately to 0.01N, the line speed can be adjusted accurately to 0.1m / min, the winding mode and the unwinding mode can be switched freely, and the relevant interface is reserved to synchronize the line speed with the laminating machine, thereby improving its stability and versatility.

[0047] In the embodiment, the first pressure sensing wheel 31 and the second pressure sensing wheel 32 can sense pressure with an accuracy of 0.01N, and can display relevant data on the numerical control panel 8 in real time.

[0048] In the embodiment, the take-up wheel 5 includes a take-up wheel support frame, and is connected to the base body 1 through the take-up wheel support frame.

[0049] like Figure 5 As shown, the steel belt wheel press machine can reduce the protective copper winding distance by adding this adjustable unwinding and rewinding device as the protective copper winding device, making the winding more neat while reducing the impact of the protective copper on the finished flexible copper clad laminate after it leaves the pressing mechanism, making it easier to process flexible copper clad laminates with special materials and special requirements. In addition, adding a winding shaft can produce multiple flexible copper clad laminate products at the same time, improving the production efficiency of the steel belt wheel press machine.

[0050] The unwinding and rewinding device of the device can also be used for unwinding. After the traditional five-axis laminating machine is equipped with this adjustable unwinding and rewinding device as a winding and unwinding device, it can produce some laminated flexible copper clad laminates according to the laminating machine capacity by adding an unwinding shaft, thereby increasing the variety of products produced by the traditional five-axis laminating machine; at the same time, by adding a rewinding shaft, multiple flexible copper clad laminate products can be produced at the same time, thereby improving the production efficiency of the traditional five-axis laminating machine.

[0051] As an independent winding and unwinding device, the utility model can cooperate with the laminating machine in the industry to meet more winding and unwinding needs of the laminating machine on the market. And its design independent of the laminating machine body also meets the special winding needs of some products.
