Description

Technical Field

[0001] This utility model relates to an unwinding device, and more particularly to a simple unwinding device for cover film laser cutting machines. Background Technology

[0002] In existing flexible circuit board manufacturing, a thin film needs to be applied to the finished product to isolate it from the external environment. During the manufacturing process, the unfolded cover film needs to be cut to a preset length using laser cutting equipment.

[0003] During normal storage, the covering film is in a rolled-up state, and it needs to go through an unwinding process during use. Currently, the conventional method is to manually pull the end of the covering film, allowing it to pass around the built-in unwinding roller, which presses it against one end of the covering film, allowing it to gradually unfold. Afterward, it is fed into the laser cutting equipment.

[0004] During this process, excessive force can easily cause abnormal deformation or tearing of the cover film. If the force is too small, the unwinding will be incomplete, and the edges or other parts of the cover film will still be in a twisted state of winding, affecting the accuracy of subsequent cutting.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a simple roll unwinding device suitable for laser cutting machines of cover film, so as to make it more industrially valuable. Utility Model Content

[0025] 5. Braking assembly 6. Intake assembly

[0026] 7. Window cover 8. Tension control machine

[0027] 9. Mounting bracket Detailed Implementation

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] like Figure 1 A simple roll unwinding device suitable for laser cutting machines of cover film includes a housing 1. Its unique feature is that a first drive unit 2 and a second drive unit are installed inside the housing 1. A first air shaft 3 is connected to the first drive unit 2, and a second air shaft 4 is connected to the second drive unit. Typically, the first air shaft 3 and the second air shaft 4 are staggered. This allows for different tension forces to be provided to the cover film feeding device of the laser cutting machine, ensuring smooth unwinding of the cover film during output and facilitating entry into the laminating process. Simultaneously, both the first drive unit 2 and the second drive unit are equipped with independent braking components 5, which can control the rotation speed of the corresponding air shaft according to the actual tension force, ensuring the tension is maintained. Furthermore, both the first air shaft 3 and the second air shaft 4 are connected to independent tension control units 8. This allows for precise control of the actual air diameter of the first air shaft 3 and the second air shaft 4, meeting the unwinding tension requirements of cover films of different materials. Moreover, to achieve an integrated layout, the tension control unit 8 is connected to an air inlet component 6. Therefore, it can be directly connected to the gas supply pipeline within the factory area without the need to configure a new gas supply pipeline.

[0030] According to a preferred embodiment of this utility model, the equipment housing 1 includes a housing body with a docking hole at the front end, through which the docking end of the air intake component 6 protrudes. This allows for a better integrated layout. Simultaneously, an adjustment window is also provided at the front end of the housing body, with the adjustment panel of the tension control machine 8 aligned with the adjustment window. The adjustment window is connected to a cover 7 via a hinge. This allows for convenient adjustment of the operating parameters of the tension control machine 8 during debugging and use without disassembling the equipment housing 1. Furthermore, a side cover is provided on the side of the housing body, with shaft docking holes on the side cover through which the first air expansion shaft 3 and the second air expansion shaft 4 pass. This achieves a moderate internal sealing of the housing body, reducing the possibility of external foreign objects intruding.

[0031] Furthermore, both the first drive device 2 and the second drive device are electric motors. The drive shaft of the motor passes through the braking assembly 5 and connects to the corresponding first air expansion shaft 3 or second air expansion shaft 4. Meanwhile, the braking assembly 5 is a magnetic powder brake. This provides variable braking force to meet braking requirements under different working conditions. Additionally, the tension control machine 8 is a pneumatic control valve, which is connected to the throttle port of the first air expansion shaft 3 or the second air expansion shaft 4 via an air guide pipe. This allows for precise control of the actual expanded diameter of the first air expansion shaft 3 or the second air expansion shaft 4, meeting the unwinding, winding, and positioning requirements of cover films of different materials.

[0032] In practical implementation, to facilitate installation on the side of the laser cutting machine, this invention includes a mounting bracket 9 connected to the rear side of the equipment housing 1. The mounting bracket 9 includes a support plate connected to the equipment housing 1, and a triangular bracket connected below the support plate. Both the support plate and the triangular bracket have several positioning holes. This allows the mounting bracket 9 to be directly mounted onto the feed bracket on the side of the laser cutting machine. Consequently, the cover film can be unwound directly during the unwinding process before entering the laser cutting machine.

[0033] Looking further ahead, considering the convenience of docking and debugging, the air intake component 6 is an air intake guide joint, which is equipped with an on / off valve.

[0034] The working principle of this utility model is as follows:

[0035] First, attach the end of the cover film to one side of the first air shaft 3. Then, continue feeding the material, returning it to one side of the second air shaft 4 via the unwinding roller of the cover film. Next, connect this end to the feed end of the laser cutting machine.

[0036] As the first drive device 2 and the second drive device operate, the cover film is fed forward. Since its two end faces pass through the sides of the first air shaft 3 and the second air shaft 4 respectively, it unfolds by contact with them, thus completing the unwinding.

[0037] When the feeding speed is greater than the cutting speed, the braking component 5 intervenes to reduce the feeding speed.

[0038] When the tension force on the covering film is too low during feeding, the tension control machine 8 intervenes to adjust the actual diameters of the first air expansion shaft 3 and the second air expansion shaft 4 to achieve better tension bonding.

[0039] It should be noted that the unwinding rollers that come with the cover film have a conventional layout, which will not be described in detail here.

[0040] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0041] 1. Equipped with an independent drive unit, it provides unwinding drive when the cover film is discharged. No manual pulling is required, ensuring a continuous and effective feeding rate.

[0042] 2. The air-expansion shaft design, combined with the existing unwinding roller layout, provides better contact stress for the cover film, allowing it to be fully unwound.

[0043] 3. Equipped with a braking component to provide a matching discharge rate based on the cutting rate.

[0044] 4. The tension can be controlled by a tension control machine and adjusted in real time according to the actual situation.

[0045] 5. The overall structure is simple and can be directly used with laser cutting machines.

[0046] Furthermore, the directions or positional relationships described in this utility model are based on the directions or positional relationships shown in the accompanying drawings. They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit 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.
