[0026] The present invention is described in detail below in conjunction with specific embodiments.

[0027] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0028] The utility model provides a copper foil feeding and unwinding device, such as Figures 1 to 6 As shown, it includes a frame 1, a loading device 2 and an unwinding device 3; the loading device 2 is connected to the frame 1 along a transverse sliding manner, and the unwinding device 3 is arranged on the frame 1; the loading device 2 is used to roll up the copper foil and transfer it to the unwinding device 3, and is also used to take away the empty reel in the unwinding device 3; the unwinding device 3 is used to receive the copper foil roll and unwind the copper foil roll.

[0029] Based on the above structural setting, the copper foil roll is automatically fed through the feeding device 2, which can continuously and quickly complete the feeding task, reduce the labor intensity of workers, greatly shorten the production cycle, and improve the overall production efficiency.

[0030] In this embodiment, the loading device 2 includes a gantry 21, a pick-and-place frame 22 and a pick-and-place mechanism 23; the pick-and-place frame 22 is vertically slidably connected to the gantry 21, and the pick-and-place mechanism 23 is arranged on the crossbeam 221 of the pick-and-place frame 22; the pick-and-place mechanism 23 includes a pick-and-place component 231, a pick-and-place sliding drive module 232, a hook-and-support connecting rod 233, a hook-and-support component 234 and a hook-and-support sliding drive module 235; the pick-and-place component 231 is provided with two groups and can be driven by the pick-and-place sliding drive module 232 to slide longitudinally on the crossbeam 221, and the two groups of pick-and-place components 231 can approach or move away from each other; the hook-and-support component 234 is provided with two groups and is located between the two groups of pick-and-place components 231, and the two groups of hook-and-support components 234 are respectively arranged at both ends of the hook-and-support connecting rod 233 and can be driven by the hook-and-support sliding drive module 235 to slide longitudinally on the crossbeam 221. Specifically, the pick-and-place rack 22 is driven by the pick-and-place drive motor 20 to slide vertically on the gantry 21. The pick-and-place assembly 231 provides an initial stable support for the copper foil roll, and the hook support assembly 234 provides an additional stable support for the copper foil roll. The cooperation between the pick-and-place assembly 231 and the hook support assembly 234 prevents the copper foil roll from shaking after being picked up, thereby reducing the risk of the copper foil roll loosening or falling off during the entire transportation process.

[0031] In this embodiment, the pick-and-place assembly 231 includes a pick-and-place arm 2311, a pick-and-place lifting drive member 2312, a pick-and-place connecting member 2313 and a pick-and-place head 2314; the pick-and-place arm 2311 is slidably connected to the beam 221 and can be driven by the pick-and-place sliding drive module 232 to slide longitudinally, the pick-and-place connecting member 2313 is slidably connected to the pick-and-place arm 2311 and can be driven by the pick-and-place lifting drive member 2312 to slide vertically on the pick-and-place arm 2311; the pick-and-place head 2314 is arranged on the pick-and-place connecting member 2313 and extends to the side close to the hook support assembly 234.

Specifically, the support connector 313 is driven by the support sliding driving member 315 to slide in the lateral direction on the support frame 311.

[0035] In this embodiment, each support connector 313 is provided with two groups of support components 314; during the operation of the equipment, when the copper foil roll on one group of support components 314 is used up and needs to be replaced, the support sliding drive 315 drives the support connector 313 to slide so that the copper foil roll prepared on the other group of support components 314 is aligned with the pneumatic support mechanism 32 described below, and production can be resumed, which reduces the waiting time for replacing the copper foil roll, thereby improving production efficiency.
