[0020] The embodiment of the present application discloses a fully automatic film winding machine.

[0021] Embodiment 1, referring to Figure 1 and Figure 2 , a fully automatic film winding machine includes a frame 1, a discharging mechanism 2, a folding mechanism 3, a film stacking mechanism 4 and a film winding mechanism 5. In Embodiment 1, the number of discharging mechanisms 2 is 3, one of the discharging mechanisms 2 supplies the separator net, and the other two discharging mechanisms 2 supply the film sheets; the folding structure is provided with a discharging mechanism 2 for supplying the separator net and a discharging mechanism 2 for supplying the film sheets on both sides respectively, and the film stacking mechanism 4 is connected to another discharging mechanism 2.

[0022] Referring to Figure 3 , the discharging mechanism 2 includes two support frames 21 installed on the frame 1, a first roller 23 installed on the support frames 21, a first cutting assembly 24 arranged at the output end of the discharging mechanism 2, and a constant pressure driving group 22 for driving the first roller 23 to rotate. There are notches on the support frames 21, and both ends of the first roller 23 are located in the notches, and the first roller 23 is restricted in the notches by bolts; The constant pressure driving group 22 includes two pressure sensors 223 installed on the frame 1, a pressure roller 224 installed at the detection end of the pressure sensor 223, a first power source 221 installed on the frame 1, and a clutch 222 installed at the output end of the first power source 221. In Embodiment 1, the first power source 221 is taken as an example of a motor, and the clutch 222 is taken as an example of an electromagnetic clutch 222. The output end of the clutch 222 is gear-connected to the first roller 23. The film sheet / separator net is drawn out from the first roller 23 and passes through the pressure roller 224 and the first cutting assembly 24 in sequence. The first power source 221 and the clutch 222 act together to make the first roller 23 receive a driving force opposite to the drawing direction, and the magnitude of this driving force is controlled by controlling the first power source 221; The first cutting component 24 includes a first cutter 241, a first mounting member 244, a first moving unit 243 for driving the cutter to move, a first lifting rod 242, and a cylinder for driving the first lifting rod 242 to move vertically. The main function of the first mounting member 244 is for the installation of devices. In Embodiment 1, the first mounting member 244 is taken as a rod member, and it can also be a plate member, a truss, etc. When cutting, the cylinder pushes the first lifting rod 242, and the first lifting rod 242 cooperates with a part of the first mounting member 244 to clamp and fix the diaphragm / separator net. At this time, the cutter cuts the diaphragm / separator net under the drive of the first moving unit 243. In Embodiment 1, the first moving unit 243 is taken as a lead screw assembly, and it can also be an electric push rod 452, a pneumatic rod, etc.

[0023] Reference Figure 4 and Figure 5 , the folding mechanism 3 includes two placing plates 31, a first transporting unit 33 for driving the placing plates 31 to move, a first clamping component 312 arranged on the placing plates 31, a pulling component 32 arranged on one side of the placing plates 31, and a folding component 34. In Embodiment 1, the first transporting unit 33 is taken as a linear transporting motor, and it can also be a lead screw assembly. The pulling component 32 is taken as a six-axis degree-of-freedom manipulator; when the pulling component 32 extracts the diaphragm / separator net from the discharging mechanism 2, the first lifting rod 242 is at the lowest position, and at this time, the diaphragm / separator net can be pulled out. During the pulling process, the pressure sensor 223 can detect the pulling force in real time, and then control the output of the first power source 221, so that the pulling component 32 maintains a stable pulling force during the pulling process, enabling the diaphragm / separator net to be pulled more precisely.

[0024] The first clamping component 312 is arranged between the two placing plates 31. The first clamping component 312 includes two sixth moving units 3121 and a pressing rod 3122. The pressing rod 3122 is connected to one of the sixth power units, and the two sixth moving units 3121 are connected in sequence, so that the pressing rod 3122 has horizontal and vertical movements, enabling the pressing rod 3122 to be hidden below the placing plates 31 and capable of pressing and fixing the middle part of the diaphragm and one end of the separator net during the folding process.

[0025] The placing plates 31 are provided with multiple negative pressure elements 311, and the negative pressure elements 311 are evenly distributed on the placing plates 31. When the diaphragm is placed on the placing plates 31, the negative pressure elements 311 adsorb the diaphragm on the placing plates 31, and the length of the diaphragm can cover the two placing plates 31, and the separator net is placed on one of the placing plates 31.

In Embodiment 1, the second linear drive unit 342 is exemplified by a cylinder, and the second transportation unit is exemplified by a linear motor. A plurality of notches are provided on the placing plate 31. The first air gripper 344 moves up and down under the action of the first linear drive unit 343. The first air gripper 344 can open 180° at the clamping position. When one side of the notch in the placing plate 31 moves to the position of the first air gripper 344, the first air gripper 344 descends to the notch in the open state. At this time, the first air gripper 344 closes to clamp one end of the diaphragm, and moves upward through the notch to lift one end of the diaphragm, and cooperates with the movement of the placing plate 31 to fold one end of the diaphragm so that one end of the diaphragm covers above the spacer mesh; after the folding is completed, the lifting plate 345 moves downward to shape the crease by pressing and heating.

[0027] After the folding is completed, one end of the folded film is clamped by the second air gripper 346, and the folded film is dragged to the film stacking structure under the action of the second transportation unit 341.
