The carrier tape 2 continues to run, and the carrier tape 2 at the tail end of the first stripping member 31 is driven to be stripped from the film material 1. After the carrier tapes 2 at the ends of the first stripping member 31 and the second stripping member 32 are stripped, the shift lever 4 returns to the original position to wait for the next film material 1, and the second stripping member 32 moves and returns to the original position along the first direction X.

In one embodiment, referring to fig. 2, a breaking slot 22 is provided on the carrier tape 2 along the running direction of the carrier tape. A cut 22 is cut in the film 1 near the carrier tape 2 of the peeling assembly 3. The breaking notch 22 may be cut in advance or may be cut in situ.

The fourth movement of the film peeling apparatus means that the lever 4 abuts against the carrier tape bearing surface 21 at the end of the second peeling member 32. The fifth movement state of the film peeling apparatus means that after the carrier tape 2 at the end of the second peeling member 32 is peeled, the carrier tape 2 continues to run to peel the carrier tape 2 at the end of the first peeling member 31. By providing the slit 22, the carrier tape 2 in contact with the edge of the film material 1 can be divided into two parts. The lever 4 is moved from the home position in the third direction Z to the bearing surface 21 of the carrier tape 2 at the end of the second stripping member 32, and as shown in fig. 7, the lever 4 is moved horizontally beyond the breaking slit 22. As shown in fig. 8, the shift lever 4 rotates a certain angle along the shift lever movement track a to the bearing surface 21 of the carrier tape 2 at the end of the second stripping member 32, and as shown in fig. 8, the shift lever 4 can completely strip the carrier tape 2 at the end of the second stripping member 32, so that the carrier tape 2 is completely separated from the edge of the film material 1. As shown in fig. 9, after the carrier tape 2 at the end of the second peeling member 32 is separated from the edge of the film material 1, the carrier tape 2 continues to run, peeling the carrier tape 2 at the end of the first peeling member 31. After the carrier tape 2 at the tail end of the first stripping piece 31 is separated from the film material 1, the deflector rod 4 returns to the original position, and the second stripping piece 32 also returns to the original position.

By providing the breaking opening 22 on the carrier tape 2, the carrier tape 2 on one side can be peeled off first, the area of the carrier tape 2 is reduced, the release force of the carrier tape 2 is reduced, and then the carrier tape 2 on the other side is peeled off normally, so that the sectional peeling of the carrier tape 2 and the film material 1 is realized.

In one embodiment, the film peeling apparatus further includes a cutter (not shown). The cutter is disposed adjacent to the unreeling portion 5 to cut the paid-out carrier tape 2 to form a breaking slit 22.

The cutter is arranged at one side of the carrying surface 21 facing away from the carrier tape 2, and the edge of the cutter faces the carrier tape 2. The carrier tape 2 moves along the first direction X, the film material 1 reaches the position of the cutter, the cutter cuts the carrier tape 2 by a corresponding length, and after the cutting is completed, the cutter returns to the original position to wait for the next film material 1. By providing the cutter, the size of the breaking opening 22 can be adjusted on site according to the size of the film 1, without limiting the size of the film 1. Further, the cutting of the breaking slits 22 and the peeling of the carrier tape 2 can be performed simultaneously, thereby saving the production cost.

In one embodiment, the film peeling apparatus further includes a controller (not shown), which is connected to the carrier tape 2, the peeling assembly 3, the lever 4, the unreeling portion 5, the cutter, and the reeling portion 6. The controller sends different commands as required to control any one or more of the operation of the carrier tape 2, the movement of the stripping assembly 3, the movement of the deflector rod 4, the rotation of the unreeling part 5 and the reeling part 6 and the cutting of the cutter.

In the utility model, the principle that the carrier tape 2 and the film material 1 are easy to release is as follows: when the shift lever 4 rotates, the carrier tape 2 receives a pressing force F1, the lower carrier tape 2 is still on the first stripping member 31, the film material 1 receives an upward reaction force F2, and the release force of the film material 1 and the carrier tape 2 is F1, so that only half of the carrier tape 2 is released, and when F1 is greater than half of F1, the upper half of the carrier tape 2 can be released. When the lower carrier tape 2 is released, the film material 1 can be released when the stress is f2 and f2 is more than half f 1.

The following describes a method for peeling a film 1 according to the present utility model, using the film 1 as an example, the method comprising:

the carrier tape 2 having the slit 22 is placed on the peeling assembly 3, and the unreeling section 5 drives the carrier tape 2 to travel in the first direction X, and the carrier tape 2 conveys the film 1 to the end of the peeling assembly 3. At this time, the operation of the carrier tape 2 is suspended, and the first driving mechanism drives the second peeling member 32 to move in the reverse direction of the first direction X, so that the tip of the first peeling member 31 is more advanced than the tip of the second peeling member 32. The second driving mechanism drives the deflector rod 4 to move to the bearing surface 21 of the carrier tape 2 at the tail end of the second stripping piece 32 along the third direction Z, and the deflector rod 4 rotates along the deflector rod movement track A by a certain angle to completely strip the carrier tape 2 and the film material 1 at the tail end of the second stripping piece 32. The carrier tape 2 continues to run and the carrier tape 2 at the end of the first separator 31 is peeled off normally. After the carrier tape 2 at the tail end of the first stripping piece 31 is separated from the edge of the film material 1, the deflector rod 4 returns to the original position, and the second stripping piece 32 returns to the original position. The carrier tape 2 continues to run, and the rest of the carrier tape 2 and the film material 1 are peeled off. After the carrier tape 2 is completely separated from the film material 1, the film material 1 is conveyed to another platform for taking materials by a standby manipulator.

The foregoing description is only of embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present utility model or directly or indirectly applied to other related technical fields are included in the scope of the present utility model.
