Fig. 6 to 9 show an actuation plan view of the joint unit supplying mechanism and the suction cup mechanism according to an embodiment of the present invention.

As shown in fig. 3(a), fig. 4(a) and fig. 6, the bonding unit supplying mechanism 4 and the suction cup mechanism 2 are in a standby state, wherein the adhesive surfaces of the first bonding unit 411 and the second bonding unit 421 of the bonding unit supplying mechanism 4 are respectively disposed on the first roller set 412 and the second roller set 422, and the first roller set 412 and the second roller set 422 are respectively disposed corresponding to the first suction cup element 23 and the second suction cup element 24; in addition, the first suction member 23 and the second suction member 24 of the suction mechanism 2 are opened (the angle between them is substantially 180 degrees) to ready to suck the first joint unit 411 and the second joint unit 421.

As shown in fig. 3(a), 4(a) and 7, the first supply component 41 and the second supply component 42 connected thereto are moved toward the suction cup mechanism 2 along the first conveying direction D1 by driving the second driving unit 43 of the joining unit supply mechanism 4. Next, the first suction pad member 23 and the second suction pad member 24 are respectively sucked to the opposite sides of the adhesive surfaces of the first bonding unit 411 and the second bonding unit 421 by the suction flow. In the present embodiment, the adsorption is performed by means of an air suction flow, but the present invention is not limited thereto; in other embodiments, the adsorption may also be performed electrostatically or otherwise.

As shown in fig. 3(a), 4(a) and 8, since one end of the first engaging unit 411 and the second engaging unit 421 is already attracted to the first suction pad element 23 and the second suction pad element 24, the second driving unit 43 is driven to move the first supply element 41 and the second supply element 42 in the second conveying direction D2, and simultaneously pull the first engaging unit 411 and the second engaging unit 421, so that the surfaces of the first suction pad element 23 and the second suction pad element 24 are covered by the first engaging unit 411 and the second engaging unit 421, respectively. In the embodiment, the surfaces of the first suction cup element 23 and the second suction cup element 24 are completely covered by the first engaging unit 411 and the second engaging unit 421, but the present invention is not limited thereto, and the ratio of the first engaging unit 411 and the second engaging unit 421 covering the surfaces of the first suction cup element 23 and the second suction cup element 24 can be adjusted according to the requirement.

As shown in fig. 3(a), 4(a) and 9, since the first bonding unit 411 and the second bonding unit 421 are adsorbed on the surfaces of the first suction member 23 and the second suction member 24, the first bonding unit 411 and the second bonding unit 421 are cut by the first cutting member 414 and the second cutting member 424 respectively disposed on the first supply member 41 and the second supply member 42, and are adsorbed on the first suction member 23 and the second suction member 24 respectively, so as to be used for film bonding. After the cutting of the first cutting element 414 and the second cutting element 424 is completed, the second driving unit 43 is driven to move the first supplying element 41 and the second supplying element 42 away from the suction cup mechanism 2 along the third conveying direction D3 and the fourth conveying direction D4, and return to the initial position (as shown in fig. 6). In the present embodiment, the joining unit supplying mechanism 4 returns to the initial position, but the present invention is not limited thereto as long as the position of the joining unit supplying mechanism 4 does not affect the subsequent operation of the suction cup mechanism 2.

Fig. 10 to 15 are schematic operation perspective views of an automatic film splicing apparatus according to an embodiment of the present invention.

As shown in fig. 10, the first shrink film 11 is supplied to the feeding mechanism 3, the first shrink film 11 is transported between the two belt fixing elements 32, and the second roller 38 is rotated to transport the first shrink film 11 in the first transport direction D1 (as shown in fig. 5 (C)), and then the first shrink film 11 is transferred from the transport in the first transport direction D1 to the transport in the fourth transport direction D4 by the turning roller 36. Meanwhile, the first bonding unit 411 and the second bonding unit 421 of the bonding unit supplying mechanism 4 are already disposed on the first suction member 23 and the second suction member 24, respectively (as shown in fig. 3a and 4 a), and are ready for film bonding. In addition, the belt 33 may also pass through the first and second layers (as shown in fig. 1 and 11) of at least one of the second shrink film 12 and the shrink films 13, 14, 15, 16 after cutting, so as to support the second shrink film 12 and the shrink films 13, 14, 15, 16 (as shown in fig. 1).

As shown in fig. 11, when the first shrink film 11 has a predetermined length, the first shrink film 11 is ready to be bonded to the second shrink film 12, so that the first shrink film 11 is cut by the cutting unit 34 of the feeding mechanism 3 (as shown in fig. 5 (a)) to form a terminal 111 on the first shrink film 11. At this time, the feeding mechanism 3 enters a ready-to-splice state, and the motor 39 drives the second roller 38 (as shown in fig. 5 (C)) via the belt 381, so as to convey the first shrink film 11 forward a certain distance, so that the terminal 111 of the first shrink film 11 moves out from the shrink film channel 10 to between the two belt fixing elements 32, thereby facilitating the subsequent splicing of the terminal 111 of the first shrink film 11 and the second shrink film 12. In the present embodiment, a detecting unit (not shown) may be provided for detecting the remaining lengths of the first shrink film 11, the second shrink film 12, and the shrink films 13, 14, 15, and 16 (as shown in fig. 1), wherein the type of the detecting unit is not limited, and may be, for example, an optical detecting unit or other detecting units.

As shown in fig. 11 and 12, the feeding mechanism 3 mounted between the first rail 51 and the third rail 53 is moved in the third conveying direction D3 by driving a third driving element (not shown). Since the belt 33 is disposed between the first film 12a and the second film 12b of the second shrink film 12, when the feeding mechanism 3 moves along the third conveying direction D3, the end 111 of the first shrink film 11 moves into between the first film 12a and the second film 12b of the second shrink film 12, that is, the first film 12a of the second shrink film 12 is located above the first shrink film 11, and the second film 12b of the second shrink film 12 is located below the first shrink film 11.

As shown in fig. 3a, 4 a and 13, the suction mechanism 2 is moved in the third conveyance direction D3 by driving a fourth driving element (not shown), and the first suction element 23 and the second suction element 24 of the suction mechanism 2 are disposed in correspondence with the first film layer 12a and the second film layer 12b of the second shrink film 12 (as shown in fig. 11) to prepare for film joining by the first joining unit 411 and the second joining unit 421.

As shown in fig. 3(a), fig. 4(a), fig. 11 and fig. 14, the first driving element 21 is driven to switch the first suction cup element 23 and the second suction cup element 24 of the suction cup mechanism 2 from the open state to the closed state (i.e. the included angle between the two is substantially switched from 180 degrees to 0 degrees), and further, the first bonding unit 411 previously disposed on the first suction cup element 23 is attached to the first film layer 12a and the first shrink film 11 of the second shrink film 12, and the second bonding unit 421 previously disposed on the second suction cup element 24 is attached to the second film layer 12b and the first shrink film 11 of the second shrink film 12, so as to successfully bond the first shrink film 11 and the second shrink film 12, thereby completing the film bonding operation.

After the first shrink film 11 and the second shrink film 12 are completely joined, as shown in fig. 3(a), 4(a) and 15, the second roller 38 of the feeding mechanism 3 resumes the rotation rate (as shown in fig. 5 (C)) and starts to feed the second shrink film 12. Next, the suction cup mechanism 2 is also returned to the initial position along the second conveying direction D2 by a fourth driving element (not shown), and the engaging unit supplying mechanism 4 provides the first engaging unit 411 and the second engaging unit 421 for the first suction cup member 23 and the second suction cup member 24 again. When the second shrink film 12 and the shrink films 13, 14, 15, 16 are about to be used (as shown in fig. 1), the bonding operation is similar to that of the first shrink film 11 after being used, and the description thereof is omitted.

Although the present invention has been described by way of examples, it is to be understood that many other modifications and variations are possible without departing from the spirit of the invention and as claimed.
