As shown in fig. 12, a rotating shaft 58 can be fixed on the bottom surface of the swing arm 51, the rotating shaft 58 penetrates through the transfer seat 52 to the inside of the workbench 1, a driving mechanism for driving the rotating shaft 58 to rotate is arranged in the workbench 1, the driving mechanism can be a first connecting rod 55, a second connecting rod 56 and a swing cylinder 57, the swing cylinder 57 is fixed to the workbench 1, one end of the first connecting rod 55 is fixed to the rotating shaft 58, and both ends of the second connecting rod 56 are respectively pivoted with the other end of the first connecting rod 55 and the end of a piston rod of the swing cylinder 57. When the piston rod of the swing cylinder 57 extends, the second connecting rod 56 is pulled, and the first connecting rod 55 and the rotating shaft 58 are driven to swing through the movement of the second connecting rod 56, so that the swing arm 51 swings back and forth between two positions. That is, the swing arm 51 swings to move the suction cup assembly 53 at the tray feeding conveyor 31 and the tray placing station 6a, and swings to move the suction cup assembly 53 at the tray taking station 6c and the discharging conveyor 4.

Furthermore, the rotating shaft 58 is fixed in the middle of the swing arm 51, and the lifting cylinder 54 and the suction cup assembly 53 are disposed at both ends of the swing arm 51, so that both ends of the swing arm 51 simultaneously and respectively operate, that is, the winding disc 25 clamped by the finger cylinder 32 of the disc feeding device is transferred to the placing shaft 62 located at the disc placing station 6a and is sleeved on the placing shaft 62, and the winding disc 25 wound with the raw material tape 24 on the placing shaft 62 located at the disc taking station 6c is taken out onto the discharging conveyor belt 4.

The control system can be a PLC controller and is used for controlling the orderly work of the power executing elements such as the motor, the cylinder and the like, and the specific working method of the utility model is as follows:

s 1: the placing shaft 62 at the rewinding station 6b drives each winding reel 25 to rotate through rotation, so as to rewind the raw material tape 24 to the winding reel 25; at the same time, the suction cup assembly 53 of the transfer device transfers the reel 25 on the feeding device to the placing shaft 62 located at the placing station 6 a; the suction cup assembly 53 of the transfer device also transfers the reel 25, which has completed rewinding the raw material tape 24 and is located on the placing shaft 62 of the reel taking station 6c, from the placing shaft 62 of the reel taking station 6c onto the outfeed conveyor belt 4;

s 2: after the winding reels 25 on the rewinding station 6b finish rewinding the raw material tapes 24, the placing shafts 62 located at the rewinding station 6b stop rotating, the rotating disc 61 rotates to drive the three placing shafts 62 to move to the next station at the same time, that is, the placing shafts 62 originally located at the rewinding station 6b move to the reel taking station 6c and pull the raw material tapes, the placing shafts 62 originally located at the reel taking station 6a move to the rewinding station 6b, and the placing shafts 62 originally located at the reel taking station 6c move to the reel taking station 6 a;

s 3: each of the heat-melting heads 672 of the heat-melting mechanism 67 moves to the rewinding station 6b to weld and fix the raw material tape 24 to the winding reel 25 positioned at the rewinding station 6 b;

s 4: the guillotine 6322 located between the placement shaft 62 of the rewinding station 6b and the placement shaft 62 of the reel taking station 6c moves outward of the turntable 61 to sever the raw material tape 24 stretched from the rewinding station 6b to each reel 25 of the reel taking station 6 c;

s 5: the above step s1 is repeated, and then the rewinding operation of the raw material tape 24 is completed.

In addition, in the above method, before the device starts to work, the original tape on the rotating rod 21 needs to be pulled to the winding disc 25 at the rewinding station 6b, and the original tape is fixed on the winding disc 25 after being pulled: the raw material tape of the whole cylinder is placed on the rotating rod 21, the raw material tape is pulled out, the raw material tape sequentially winds around each roller 23, the raw material tape is cut by each blade of the cutting mechanism 22 to form a plurality of strip raw material tapes 24, the raw material tape 24 positioned above the raw material tapes 24 which are sequentially formed into a group in pairs is pulled to one rewinding device from top to bottom, the raw material tape 24 positioned below is pulled to the other rewinding device, in the rewinding device, each raw material tape 24 is wound to each winding disc 25 on the placing shaft 62 used for the rewinding station 6b, and the end part of the raw material tape 24 is welded and fixed on each winding disc 25 through the hot melting mechanism 67, so that the raw material tape cutting and pulling can be completed.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
