Compared with rigid copper-clad plate, flexible copper foil substrate has the characteristics of thinness, lightness and flexibility. Flexible printed circuit boards using flexible copper foil substrate as substrate material are widely used in electronic products such as mobile phones, digital cameras, digital video cameras, car satellite direction positioning devices, liquid crystal televisions and notebook computers. Because of its good flexibility, it is often necessary to wind it up for storage during production. However, the existing winding device is not convenient for loading and unloading flexible copper foil substrate coils, which affects production efficiency. SUMMARY

[0003] In view of the above problems, the purpose of the utility model is to design a flexible copper foil substrate winding device to improve the loading and unloading efficiency of flexible copper foil substrate coils and thus improve production efficiency.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] A flexible copper foil substrate winding device is designed, which includes a winding assembly.

[0015] Further, the base is further provided, the first rack is arranged on the base, the first rack further comprises a connecting frame connecting the first supporting column and the second supporting column, and a plurality of rollers are rotatably arranged on the bottom of the connecting frame.

[0016] In the scheme, the winding assembly is slidably arranged on the base and can move along the direction perpendicular to the conveying direction of the copper foil substrate, and the automatic adjustment of the position of the winding assembly is realized by cooperating with the control system, so that the deviation of the copper foil substrate during winding can be corrected by moving the winding assembly.

[0017] Further, the base is further provided, the first rack is arranged on the base, the first rack further comprises a connecting frame connecting the first supporting column and the second supporting column, and a plurality of rollers are rotatably arranged on the bottom of the connecting frame.

[0020] The driving member is an electric cylinder, the output end of the electric cylinder is connected to the connecting frame through a connecting member, and the movement of the winding assembly is accurately controlled.

[0021] Further, the second rack, the tensioning roller rotatably arranged on the second rack, and at least one pressing unit are further provided, and the pressing unit is movable along the axial direction of the tensioning roller.

[0022] By arranging the tensioning roller to apply appropriate pressure, it is ensured that the copper foil substrate is always in a tensioning state during winding, so that the copper foil substrate is prevented from being disordered or damaged due to relaxation, the copper foil substrate is pressed and adhered to the tensioning roller by the pressing unit, so that the copper foil substrate is prevented from being wrinkled during conveying, in addition, the pressing unit is designed to be adjustable in position, so that the winding of copper foil substrates with different widths and sizes can be realized, and the compatibility is improved.

[0023] Furthermore, the second frame is provided with a sliding plate parallel to the tension roller.

[0024] The pressure roller is pressed against the tension roller by the elastic force of the torsion spring, which can prevent the copper foil substrate from wrinkling during the conveying process. By adjusting the position of the connecting plate on the sliding plate, the position of the pressure roller relative to the tension roller can be changed, thereby meeting the winding requirements of copper foil substrates of different widths and improving compatibility.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] In this design, the flexible copper foil substrate roll is fixedly mounted on a rotating shaft. A drive motor rotates the shaft, which in turn rotates the roll to wind up the flexible copper foil substrate. Specifically, during loading, the limiting locking structure is loosened to allow the movable end of the rotating shaft to disengage from it. Then, the shaft is pushed to rotate horizontally around the first support column, moving its movable end away from the second support column, thus mounting the roll onto the shaft. Finally, the shaft is rotated again to engage the movable end with the limiting locking structure and secure it, completing the loading process. During unloading, the flexible copper foil substrate roll is unloaded and loaded onto the roll in the same manner. This structural design allows for rapid loading and unloading without disassembling the entire rotating shaft, significantly improving loading and unloading efficiency. It also enables standardized loading and unloading operations, facilitating the introduction of automated loading and unloading equipment to replace manual loading and unloading, further enhancing efficiency and saving labor costs.

The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] As shown in Figure 1 and Figure 2 , the present embodiment provides a flexible copper foil substrate winding device, which comprises a winding assembly 1, the winding assembly 1 comprising a first rack 11 and a rotating shaft 12 rotatably arranged on the first rack 11, the first rack 11 comprising a first support column 111, a second support column 112, and a rotating part 114 horizontally rotatably arranged on the top of the first support column 111, the rotating shaft 12 comprising a fixed end 121 and a movable end 122, the fixed end 121 being rotatably connected to the rotating part 114, the second support column 112 being provided with a limiting and locking structure 113, the rotating part 114 being horizontally rotatable to drive the rotating shaft 12 to rotate so that the movable end 122 of the rotating shaft 12 is disengaged or clamped to the limiting and locking structure 113. In addition, a driving motor is also arranged on the rotating part 114, the output end of the driving motor being drivingly connected to the fixed end 121 of the rotating shaft 12, the rotating shaft 12 being driven to rotate by the driving motor to complete the winding of the flexible copper foil substrate. In the present embodiment, the rotating shaft 12 is a gas expansion shaft, which can realize the fixation of the winding drum of the flexible copper foil substrate after being injected with compressed air by an external air source. In other possible embodiments, the rotating shaft 12 can also adopt other structures to realize the fixation of the winding drum of the flexible copper foil substrate.

[0035] As shown in Figure 2 and Figure 3As shown, the limiting and locking structure 113 comprises a limiting groove 1131 and a locking piece 1132. When the movable end 122 of the rotating shaft 12 is clamped to the limiting and locking structure 113, the outer periphery of the movable end 122 of the rotating shaft 12 is fitted to the inner wall of the limiting groove 1131, and the locking piece 1132 abuts against the outer periphery of the movable end 122 of the rotating shaft 12. The limiting groove 1131 is a U-shaped groove, which supports the movable end 122 of the rotating shaft 12. The upper and lower walls of the limiting groove 1131 limit the jumping of the rotating shaft. The movable end 122 of the rotating shaft 12 is locked by the locking piece 1132, so that the rotating shaft 12 is completely fixed and cannot jump or move during rotation. The locking piece 1132 comprises a locking column 1133 and a rotating handle at the end of the locking column 1133. The top of the second supporting column 112 is provided with a first threaded hole 1121 communicating with the limiting groove 1131.

When the movable end 122 of the rotating shaft 12 needs to be locked, the end of the locking column 1133 is moved downward to abut against the outer periphery of the movable end 122 of the rotating shaft 12, so that the movable end 122 of the rotating shaft 12 is pressed in the limiting groove 1131. Conversely, when the movable end 122 of the rotating shaft 12 needs to be released, the rotating handle is reversely rotated. The limiting and locking structure 113 further comprises an adjusting piece 1134. The adjusting piece 1134 comprises an adjusting column 1135 and a rotating handle at the end of the adjusting column 1135. The side surface of the second supporting column 112 is provided with a second threaded hole 1122 communicating with the limiting groove 1131. The adjusting column 1135 is screw-connected to the second threaded hole 1122. The rotating handle is rotated to move the adjusting column 1135. The end of the adjusting column 1135 contacts the outer periphery of the movable end 122 of the rotating shaft 12 to drive the movable end 122 of the rotating shaft 12 to move in the limiting groove 1131. The adjusting piece 1134 is used for fine adjustment of the position of the rotating shaft 12 and limiting. The rotating shaft 12 can be perpendicular to the conveying direction of the copper foil substrate, so that the edges of the copper foil substrate are not uneven when the copper foil substrate is wound. In this embodiment, the movable end 122 of the rotating shaft 12 comprises a bearing 1221 sleeved on the rotating shaft 12. The inner ring of the bearing 1221 is fixed on the rotating shaft 12. The outer ring of the bearing 1221 matches the limiting groove 1131. When the bearing 1221 is placed in the limiting groove 1131, the bearing 1221 is locked by the locking piece 1132, so that the rotating shaft 12 is completely fixed.

[0036] In the example, the reel sleeve of the flexible copper foil substrate is fixed on the rotating shaft 12, and the reel is rotated by the rotating shaft 12 to realize the winding of the flexible copper foil substrate. Specifically, when loading, loosen the limiting locking structure 113 to make the movable end 122 of the rotating shaft 12 can be separated from the limiting locking structure 113, then push the rotating shaft 12 to make it rotate horizontally around the first support column 111 to make its movable end 122 away from the second support column 112, the reel sleeve is set on the rotating shaft 12, and finally rotate the rotating shaft 12 to make its movable end 122 clamped into the limiting locking structure 113 and fixed, that is, the loading is completed; when unloading, the flexible copper foil substrate coil is unloaded in the same way and the reel is loaded. Through the above structure design, the rotating shaft 12 does not need to be disassembled as a whole, and the loading and unloading can be quickly completed, which greatly improves the loading and unloading efficiency, and at the same time realizes the standard operation of loading and unloading, which is beneficial to the introduction of automatic loading and unloading equipment, replacing manual loading and unloading, to further improve the loading and unloading efficiency and save labor cost.

If deviation occurs, a signal is transmitted to the control system, and the control system controls the driving member 22 to drive the winding assembly to move in a direction perpendicular to the conveying direction of the copper foil substrate, thereby realizing the deviation correction of the copper foil substrate winding. By setting the guide groove 21 on the base 2 to limit and guide the rollers 1151, the deviation of the winding assembly 1 during movement can be avoided, and the stability of the movement of the winding assembly 1 is improved.
