Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature.

[0031] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0033] Example:

[0034] See also Figures 1 and 2The flexible film loading and unloading device in a preferred embodiment of the present invention includes an unwinding member 1, a first guide rail 2, a second guide rail 3, and a rewinding member 4, which are sequentially arranged along the production direction. The flexible film is unwound by the unwinding member 1 and rewound by the rewinding member 4, and the flexible film passes over the surfaces of the first guide rail 2 and the second guide rail 3. It can be understood that the flexible film is initially received and unwound by the unwinding member 1, passes through the first guide rail 2 and various process steps, passes through the second guide rail 3, and is finally rewound by the rewinding member 4.

[0035] Among them, such as Figure 2 As shown, in a preferred embodiment, the winding element 4 is connected to a driving element 5, which is capable of driving the winding element 4 to rotate. In a specific implementation, the driving element 5 can be a drive motor capable of driving the winding element 4 to rotate, without further limitation. It is understood that when the driving element 5 drives the winding element 4 to rotate, the winding element 4 can drive the flexible film wound thereon to move, thereby driving the unwinding element 1 connected to the other end of the flexible film to rotate, thereby achieving unwinding of the unwinding element 1, forming a winding and unwinding cycle.

[0036] During specific implementation, both the winding member 4 and the unwinding member 1 can use hand-expanding shafts, and limit members are connected on both sides to achieve the storage of the flexible film. In the preferred embodiment, the unwinding member 1 is connected to a first control member, and the first control member can control the unwinding tension of the unwinding member 1. Similarly, the winding member 4 is also connected to a second control member, and the second control member can control the winding tension of the winding member 4. Preferably, in the preferred embodiment, the first control member and the second control member adopt magnetic powder clutches. It can be understood that the magnetic powder clutch is a relatively mature technology, and the effect of controlling the tension can be achieved by selecting an existing magnetic powder clutch. The magnetic powder clutch can perform PID control (i.e., proportional-integral-derivative control) by setting data such as the roll diameter, film thickness, and magnetic powder force in advance to ensure that the tension of the flexible film remains constant during continuous operation.

[0037] On this basis, in a preferred embodiment, the unwinding member 1 is also connected to a third detection member, which is electrically connected to the first control member. The third detection member is used to detect the number of rotations of the unwinding member 1 and transmit the detected data to the first control member. Similarly, in a preferred embodiment, the winding member 4 is also connected to a fourth detection member, which is electrically connected to the second control member. The fourth detection member is used to detect the number of rotations of the winding member 4 and transmit the detected data to the second control member. In specific implementation, both the third detection member and the fourth detection member can be selected from sensors that can detect the number of rotations of the unwinding member 1 and the winding member 4, and no excessive restrictions are imposed here. The magnetic powder clutch, based on the setting of the roll diameter, film thickness, and magnetic powder force, combines the sensor to monitor the number of rotations for PID control, so that the tension can be kept constant during continuous operation.

[0038] Further, if Figure 1 As shown, in a preferred embodiment, the first guide rail 2 is connected to a first host computer 6, and the first host computer 6 can control the movement of the first guide rail 2. It is understandable that in a specific implementation, the first guide rail 2 may include a driving device and two movable rollers provided at both ends, and the driving device drives the movable rollers to rotate so that the flexible film passing through the first guide rail 2 is moved by the first guide rail 2. Among them, the first host computer 6 can use a deviation corrector, which is an existing mature technology, or any existing device that can control the first guide rail 2, without making too many restrictions here. Pre-settings can be made in advance on the first host computer 6 so that the flexible film always passes through a preset position to prevent the flexible film from serpentine or uneven edges when entering the next process.

[0039] On this basis, in a preferred embodiment, the first guide rail 2 is further connected to a first detection element for detecting the position of the flexible film on the first guide rail 2. The first detection element is electrically connected to the first host computer 6 and transmits the detected data to the first host computer 6. In a specific implementation, the first detection element can be a side edge sensor that can detect the current position of the film in real time and provide real-time feedback to the first host computer 6, allowing the first host computer 6 to perform real-time deviation correction, ensuring that the flexible film does not move arbitrarily while passing through the first guide rail 2 and cannot enter the next process correctly.

[0040] Similarly, if Figure 2 As shown, in a preferred embodiment, the second guide rail 3 is connected to a second host computer 7, and the second host computer 7 is capable of controlling the movement of the second guide rail 3. It is understandable that, in a specific implementation, the second guide rail 3 may include a driving device and two movable rollers provided at both ends, and the driving device drives the movable rollers to rotate so that the flexible film passing through the second guide rail 3 is moved by the second guide rail 3. Among them, the second host computer 7 can also use a deviation corrector, which is an existing mature technology, or any existing device capable of controlling the second guide rail 3 can be selected, and no excessive restrictions are imposed here. Pre-settings can be made in advance on the second host computer 7 so that the flexible film always passes through a preset position to prevent the flexible film from snaking or having uneven edges when entering the next process.

[0041] On this basis, in a preferred embodiment, the second guide rail 3 is further connected to a second detection element for detecting the position of the flexible film on the second guide rail 3. The second detection element is electrically connected to the second host computer 7 and transmits the detected data to the second host computer 7. In a specific implementation, the second detection element can be a side edge sensor that can detect the current position of the film in real time and provide real-time feedback to the second host computer 7, allowing the second host computer 7 to perform real-time deviation correction, ensuring that the flexible film does not move arbitrarily while passing through the second guide rail 3 and fail to enter the next process correctly.

[0042] In addition, in the preferred embodiment, the flexible film loading and unloading device also includes a first mounting member and a first steering member 8. The unwinding member 1 and the first guide rail 2 can be installed on the first mounting member according to actual conditions, or the unwinding member 1 and the first guide rail 2 can be directly connected to the site where the device is located. Adjustments can be made according to actual conditions, and no excessive restrictions are imposed here. The first steering member 8 is installed on the first mounting member. The first steering member 8 can optionally use a steering roller. Its installation on the first mounting member is conducive to subsequent connection with the site, and the first steering member 8 itself is also more stable. The first steering member 8 is located on the side of the first guide rail 2 away from the unwinding member 1, that is, the flexible film is turned through the first steering member 8 after coming out of the first guide rail 2, so that subsequent process processing can be better performed.

[0043] Similarly, in the preferred embodiment, the flexible film loading and unloading device also includes a second mounting member 9 and a second steering member 10. The second steering member 10 is mounted on the second mounting member 9 and is located on the side of the second guide rail 3 away from the winding member 4. The winding member 4 and the second guide rail 3 can both be mounted on the second mounting member 9 according to actual conditions, or the winding member 4 and the second guide rail 3 can be directly connected to the site where the device is located. Adjustments can be made according to actual conditions and are not subject to excessive restrictions. The second steering member 10 is mounted on the second mounting member 9. The second steering member 10 can optionally use a steering roller. Its installation on the second mounting member 9 facilitates subsequent connection with the site, and the second steering member 10 itself is also more stable. The second steering member 10 is set at the position where the flexible film comes out of the previous process and does not need to enter the second guide rail 3 and be wound by the winding member 4. In this way, it can be turned through the second steering member 10 as needed after processing, thereby enabling better winding.

[0044] The flexible film loading and unloading device of this utility model can prevent the flexible film from snaking during transportation or having uneven edges when entering the next process. A detection component is provided to detect the current position of the flexible film in real time, providing real-time feedback to the host computer for real-time correction. Furthermore, a control component is provided to control the tension of the flexible film during loading and unloading, preventing deformation of the flexible film during transportation. The utility model has excellent practical value and application prospects.

[0045] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
