[0030] like Figures 1 to 3 As shown, a simple roll-to-roll copper foil tensioning device described in one embodiment of the utility model includes a tensioning mechanism 1 and a clamping mechanism 2 arranged at the movable end of the tensioning mechanism 1, the clamping mechanism 2 clamps the edge of the copper foil 4 so that the copper foil 4 is suspended, and the tensioning mechanism 1 drives the clamping mechanism 2 to move to tension the copper foil 4.

[0031] When using the tensioning device, the operator first places the edge of the copper foil 4 into the clamping mechanism 2, and manipulates the clamping mechanism 2 to firmly clamp the copper foil 4. Subsequently, the tensioning mechanism 1 is started, which drives the clamping mechanism 2 and the clamped copper foil 4 to move together through the movement of its movable end. During the movement, due to the fixation of the clamping mechanism 2 and the tension of the tensioning mechanism 1, the copper foil 4 is tensioned and remains suspended. The tensioning mechanism 1 can adjust the tension of the copper foil 4 according to the processing requirements to ensure that the copper foil 4 remains flat and stable during the processing. When the copper foil 4 reaches the predetermined tension level, the tensioning mechanism 1 stops moving, and the clamping mechanism 2 continues to clamp the copper foil 4, providing stable support for subsequent laser processing.

[0032] The tensioning device realizes the suspended tensioning of the copper foil 4 through the coordinated action of the tensioning mechanism 1 and the clamping mechanism 2, effectively solving the problem that the copper foil 4 cannot be suspended tensioned in the traditional processing method. The tensioning device has a simple and practical structure, is easy and quick to operate, and greatly improves the processing efficiency and processing accuracy. At the same time, the device also has good adaptability and stability, can adapt to the processing requirements of copper foils 4 of different widths, and ensures safety and reliability during the processing.

[0033] like Figure 3 As shown, in a preferred embodiment, the tensioning mechanism 1 includes a longitudinal tensioning assembly 101 and a transverse tensioning assembly 102 . The longitudinal tensioning assembly 101 is used to tension the copper foil 4 along its length direction, and the transverse tensioning assembly 102 is used to tension the copper foil 4 along its width direction.

[0034] When the tensioning device is working, the longitudinal tensioning assembly 101 controls the moving speed and distance of its active end to achieve tensioning in the length direction of the copper foil 4. The transverse tensioning assembly 102 controls the moving speed and distance of its active end to tension in the width direction of the copper foil 4. The two tensioning assemblies work together to ensure that the copper foil 4 can achieve an ideal tensioning state in both the length and width directions.

[0035] The device adopts a combination of a longitudinal tensioning component 101 and a transverse tensioning component 102 to achieve all-round tensioning of the copper foil 4, which can effectively prevent the copper foil 4 from loosening or deforming during processing, and improve the processing accuracy and stability of the copper foil 4. At the same time, the coordinated work of the longitudinal and transverse tensioning components 102 also improves processing efficiency and reduces production costs.

[0036] Specifically, Figure 5 and Figure 7As shown, the transverse tensioning assembly 102 includes a base plate 103, a transverse slide rail 104 is provided on the base plate 103, a transverse slider 105 is provided on the transverse slide rail 104, a transverse tensioning cylinder 106 is provided on one side of the transverse slider 105, the piston rod of the transverse tensioning cylinder 106 is connected to the transverse slider 105, and the piston rod of the transverse tensioning cylinder 106 is telescopically driven to slide the transverse slider 105 on the transverse slide rail 104.

[0037] During operation, the piston rod of the transverse tensioning cylinder 106 begins to extend and retract, driving the transverse slider 105 to slide on the transverse slide rail 104, so that the transverse slider 105 and the clamping mechanism 2 connected thereto generate a transverse tensile force on the copper foil 4, thereby achieving tensioning of the copper foil 4 in the width direction. When the predetermined tensioning degree is reached, the piston rod of the transverse tensioning cylinder 106 stops extending and retracting, and the transverse slider 105 and the clamping mechanism 2 remain in the current position, ensuring that the copper foil 4 remains in a stable tensioning state throughout the entire processing process.

[0038] This embodiment realizes precise tensioning control of the copper foil 4 in the width direction through the transverse tensioning assembly 102. The combination of the transverse slide rail 104 and the transverse slider 105 ensures the smoothness and precision of the sliding, making the tensioning process more reliable. At the same time, the piston rod of the transverse tensioning cylinder 106 is telescopically driven to provide sufficient power during the tensioning process to ensure the tensioning effect. In addition, the assembly has a simple structure and is easy to operate. It can quickly adapt to the processing requirements of copper foils 4 of different widths, thereby improving production efficiency and processing quality.

[0039] like Figures 4 to 7 As shown, in a preferred embodiment, a fixed slider 107 is slidably arranged on the transverse slide rail 104, and the transverse tensioning cylinder 106 is arranged on the fixed slider 107. An adjustment connecting block 108 is arranged on one side of the fixed slider 107, and a waist hole is arranged on the adjustment connecting block 108. A plurality of connecting holes are arranged on the bottom plate 103, and an adjusting bolt 304 threadedly connected to the connecting hole is arranged through the waist hole.

[0040] When the width of the copper foil 4 to be processed changes, the operator adjusts the position of the fixed slider 107 to adapt to the copper foil 4 of different widths. Specifically, first loosen the adjustment bolt 304 in the waist hole to allow the fixed slider 107 to slide freely on the transverse slide rail 104. Then, slide the fixed slider 107 to a suitable position according to the actual width of the copper foil 4. Finally, the fixed slider 107 is firmly connected to the bottom plate 103 by adjusting the bolt 304 to ensure that the fixed slider 107 does not move during the processing.

[0041] In this embodiment, by setting up structures such as a fixed slider 107, an adjustable connecting block 108 and an adjusting bolt 304, the operator can adjust the position of the fixed slider 107 to quickly adapt to the processing requirements of copper foils 4 of different widths. The lateral tensioning assembly 102 has good adaptability and flexibility.

[0042] In practical applications, the fixed slider 107 and the width adjustment can be used alone for lateral tensioning, that is, tensioning is adjusted manually.

[0043] Specifically, Figure 6 As shown, the longitudinal tensioning assembly 101 includes a longitudinal slide rail 109, a longitudinal slider 110 is arranged on the longitudinal slide rail 109, a longitudinal tensioning cylinder 111 is arranged on one side of the longitudinal slider 110, the piston rod of the longitudinal tensioning cylinder 111 is connected to the longitudinal slider 110, and the piston rod of the longitudinal tensioning cylinder 111 is telescopically driven to drive the longitudinal slider 110 to slide on the longitudinal slide rail 109.

[0044] During operation, the piston rod of the longitudinal tensioning cylinder 111 is extended and retracted, and the longitudinal slider 110 slides smoothly on the longitudinal slide rail 109, driving the clamping mechanism 2 connected thereto to move along the length direction of the copper foil 4, so that the clamping mechanism 2 generates a longitudinal tensile force on the copper foil 4, thereby achieving tensioning of the copper foil 4 in the length direction. When the predetermined tensioning degree is reached, the piston rod of the longitudinal tensioning cylinder 111 stops extending and retracting, and the longitudinal slider 110 and the clamping mechanism 2 remain in the current position, ensuring that the copper foil 4 remains in a stable tensioning state throughout the entire processing process.

[0045] In this embodiment, the copper foil 4 is effectively tensioned and controlled in the length direction by the longitudinal tensioning assembly 101. The combination of the longitudinal slide rail 109 and the longitudinal slider 110 ensures the smoothness and precision of the sliding and the reliability of the tensioning process. At the same time, the piston rod telescopic drive of the longitudinal tensioning cylinder 111 provides power support for the tensioning process, so that the copper foil 4 can quickly reach the required tensioning degree. In addition, the assembly is simple to operate and easy to adjust, and can quickly adapt to the processing requirements of copper foils 4 of different lengths, thereby improving production efficiency and processing quality.

[0046] like Figure 3 As shown, in a preferred embodiment, a horizontal adjustment mechanism 3 is provided between the tensioning mechanism 1 and the clamping mechanism 2, and the horizontal adjustment mechanism 3 is used to adjust the height of each clamping mechanism 2 so that the copper foil 4 is horizontal.

[0047] After the copper foil 4 is tensioned by the tensioning mechanism 1 , the operator adjusts the height of each clamping mechanism 2 through the horizontal adjustment mechanism 3 according to the actual state of the copper foil 4 and processing requirements until the copper foil 4 is in a horizontal state.

[0048] In this embodiment, by providing a horizontal adjustment mechanism 3, the copper foil 4 tensioning device can achieve precise control of the horizontality of the copper foil 4, effectively preventing the copper foil 4 from tilting or being uneven during processing, thereby improving processing accuracy and product quality.

[0049] Specifically, Figure 2 and Figure 4 As shown, the horizontal adjustment mechanism 3 includes a vertical plate 301, an adjustment fixing seat 302 is arranged on one side of the vertical plate 301, an adjustment block 303 is slidably arranged on the vertical plate 301, an adjustment bolt 304 connected to the adjustment block 303 is threadedly connected on the adjustment fixing seat 302, and the adjustment bolt 304 is rotated to drive the adjustment block 303 to slide horizontally, and a sliding seat 305 is arranged on the other side of the vertical plate 301, a first inclined surface 306 is arranged on the adjustment block 303, and a second inclined surface 307 in sliding contact with the first inclined surface 306 is arranged on the sliding seat 305, and the horizontal sliding of the adjustment block 303 drives the sliding seat 305 to move vertically.

[0050] A scale 308 is provided on one side of the top of the adjustment fixing seat 302 close to the adjustment block 303 .

[0051] When using the horizontal adjustment mechanism 3, the operator determines the initial position and the expected adjustment range by observing the scale 308 on the adjustment fixing seat 302. Then, the operator turns the adjustment bolt 304 to drive the adjustment block 303 to slide horizontally on the vertical plate 301. As the adjustment block 303 slides, the first inclined surface 306 on it comes into sliding contact with the second inclined surface 307 on the sliding seat 305, thereby pushing the sliding seat 305 to move in the vertical direction. By continuously fine-tuning the adjustment bolt 304, the operator can control the moving distance of the sliding seat 305, thereby achieving precise adjustment of the height of the clamping mechanism 2 until the copper foil 4 reaches a horizontal state.

[0052] In this embodiment, the operator can adjust the height of the clamping mechanism 2 conveniently and quickly through the horizontal adjustment mechanism 3 to ensure that the copper foil 4 remains horizontal during processing. The scale 308 on the adjustment holder 302 makes the adjustment process more intuitive, and the operator can quickly determine the adjustment range and position according to the scale 308. In addition, the mechanism has a compact structure and stable operation, and can maintain the adjustment accuracy for a long time, effectively improving the quality and efficiency of copper foil 4 processing.

[0053] like Figure 2As shown, in a preferred embodiment, the clamping mechanism 2 includes a fixed clamping member 201 and a movable clamping member 202 arranged below the fixed clamping member 201, a clamping cylinder 203 is arranged below the movable clamping member 202, and the piston rod of the clamping cylinder 203 is connected to the movable clamping member 202. The piston rod of the clamping cylinder 203 is extended to drive the movable clamping member 202 to approach the fixed clamping member 201 for clamping the copper foil 4, and the piston rod of the clamping cylinder 203 is contracted to drive the movable clamping member 202 away from the fixed clamping member 201 for loosening the copper foil 4.

[0054] Antistatic silicone sleeves are provided on the outside of the fixed clamping member 201 and the movable clamping member 202 .

[0055] If the copper foil 4 needs to be clamped, the piston rod of the clamping cylinder 203 is extended, and the movable clamping member 202 is driven to approach the fixed clamping member 201. When the distance between the movable clamping member 202 and the fixed clamping member 201 is less than the thickness of the copper foil 4, the two clamp the copper foil 4 together to fix it. If the copper foil 4 needs to be loosened, the piston rod of the clamping cylinder 203 is retracted, and the movable clamping member 202 moves away from the fixed clamping member 201, and the copper foil 4 is released.

[0056] In this embodiment, by setting the clamping mechanism 2, the movable clamping member 202 and the fixed clamping member 201 are used in coordination, so that the clamping process of the copper foil 4 is fast and stable. The piston rod of the clamping cylinder 203 is telescopically driven to provide stable power for the clamping and loosening operations. By setting the anti-static silicone sleeve, not only the copper foil 4 is protected from electrostatic damage, but also the friction of the clamping member is enhanced, and the stability of the clamping is improved.

[0057] like Figures 4 to 7 As shown, in this embodiment, there are four clamping mechanisms 2, namely, the first clamping mechanism 2, the second clamping mechanism 2, the third clamping mechanism 2 and the fourth clamping mechanism 2. The first clamping mechanism 2 and the second clamping mechanism 2 form a pair and are jointly arranged on a transverse slide rail 104; the third clamping mechanism 2 and the fourth clamping mechanism 2 form a pair and are jointly arranged on another transverse slide rail 104; a pair of two clamping mechanisms 2 clamps the two sides of the copper foil 4 respectively. The same tensioning components are arranged on only two clamping mechanisms 2 on the same side in the same direction, that is, two transverse tensioning components 102 and two longitudinal tensioning components 101 are arranged respectively. In the width direction of the copper foil 4, the two transverse tensioning components 102 are respectively connected to the second clamping mechanism 2 and the fourth clamping mechanism 2; in the length direction of the copper foil 4, the two longitudinal tensioning components 101 are respectively connected to the third clamping mechanism 2 and the fourth clamping mechanism 2. It is not necessary to connect the clamping components to each clamping mechanism 2, so that the structure is simpler and the copper foil 4 can be ensured to be tensioned in the air.

[0058] 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 should be included in the protection scope of the present invention.
