As shown in fig. 1 and fig. 2, a film tearing apparatus 1 according to an embodiment of the present invention includes a support 12 and a flexible plate 13.

And then the movable end 133 is pulled to make the movable end 133 far away from the vacuum jig plate, and due to the flexibility of the flexible plate 13, the flexible plate 13 gradually separates from the vacuum jig plate from the movable end 133 to the fixed end 131, so as to drive the proton membrane to gradually separate from the vacuum jig plate. Compared with the existing vacuum suction plate, the membrane tearing device can smoothly separate the proton membrane from the vacuum jig plate, and the damage of the proton membrane is avoided.

It is unambiguously determined that the flexible plate 13 is deformable, and if the suction surface 132 is directly attached to a flat surface, and then the movable end 133 is pulled, the flexible plate 13 will gradually detach from the surface from the movable end 133 to the fixed end 131.

In addition, the materials can be other structures needing the film tearing treatment, as long as the structures need the film to be torn off and positioned on a flat surface.

In some embodiments, the film tearing device further comprises a base 11, and the support 12 is reciprocally movably disposed on the base 11 along the third direction and the fourth direction. Thus, the vacuum jig plate with the proton membrane can be placed at a predetermined position, and then the support 12 is moved to the corresponding position to ensure that the adsorption surface 132 adsorbs the proton membrane.

In the illustrated embodiment, the third direction is a left-right direction shown in fig. 1, i.e., a first direction, and the fourth direction is a top-bottom direction shown in fig. 1, i.e., a second direction.

While in other embodiments, since the third and fourth directions are the directions in which the support 12 moves, there may be a difference from the first and second directions, i.e., the third and fourth directions may also be different from the first and second directions.

In some embodiments, the film tearing device further includes a first driving member 14 and a second driving member 15, the first driving member 14 is disposed on the base 11 and is in transmission connection with the second driving member 15 for driving the second driving member 15 to move back and forth along the third direction, and the second driving member 15 is in transmission connection with the support 12 for driving the support 12 to move back and forth along the fourth direction.

In practice, the first driving member 14 and the second driving member 15 are linear modules.

In practical application, the connecting plate 121 and the end plate 125 both extend lengthwise along a third direction perpendicular to the first direction and the second direction, and the two side plates 123 both extend lengthwise along the first direction and are arranged at intervals along the third direction. Specifically, opposite ends of each side plate 123 are fixedly connected to ends of the connecting plate 121 and the end plate 125, respectively, to form a rectangular frame structure.

The third direction is the up-down direction in fig. 2, and the first direction in fig. 2 is the left-right direction.

In some embodiments, the film tearing device further includes a pressing member 16, the pressing member 16 is connected to the bracket 12 in a reciprocating manner along the first direction, and the pressing member 16 always presses against a surface of the flexible board 13 on a side facing away from the adsorption surface 132 along the direction during the reciprocating movement along the first direction.

So, after adsorbing adsorption surface 132 in the proton membrane, ensure to compress tightly 16 and support and press in the expansion end 133 of flexplate 13, then will stimulate expansion end 133 for expansion end 133 keeps away from the vacuum tool board, and flexplate 13 can keep away from the vacuum tool board from expansion end 133 to stiff end 131 gradually, and the in-process of keeping away from can have a thrust along first direction to compressing tightly 16, promotes to compress tightly 16 and follow expansion end 133 and remove towards stiff end 131.

Meanwhile, since the flexible board 13 has flexibility and the movable end 133 is initially located at the adsorption position, the pressing member 16 initially presses the movable end 133 onto the vacuum jig board. And the in-process that vacuum tool slab band clamp piece 16 removed towards stiff end 131 is kept away from to expansion end 133, compresses tightly piece 16 and can press flexible plate 13 gradually to improve the adsorption effect of adsorption plane 132 to the proton membrane, can ensure that flexible plate 13 drives the in-process proton membrane that the proton membrane breaks away from the vacuum tool board and can not break away from with adsorption plane 132, thereby improve the effect of tearing the membrane.

It will be appreciated that, as described above, the moving end 133 pushes the pressing member 16 to move toward the fixed end 131 while moving away from the vacuum jig plate, and the gradual movement of the moving end 133 limits the stroke of the reciprocating movement of the pressing member 16 in the first direction, and ultimately limits the movement of the pressing member 16 in this embodiment.

Further, the sliding grooves 122 are formed in two opposite sides of the bracket 12 along the third direction, the sliding grooves 122 extend along the first direction, and the pressing member 16 is disposed in the two sliding grooves 122 along the first direction in a reciprocating manner at two opposite ends of the third direction.

In practical applications, the two sliding grooves 122 are respectively disposed on the two side plates 123, and the two sliding grooves 122 respectively penetrate through the two side plates 123 along the third direction.

In some embodiments, the pressing member 16 includes a pressing portion 161 and a connecting portion 162 connected to two opposite ends of the pressing portion 161 along the third direction, when the movable end 133 is located at the suction position, the pressing portion 161 presses against a surface of the flexible board 13 facing away from the suction surface 132 along the second direction, and the two connecting portions 162 are connected to two opposite sides of the bracket 12 along the third direction in a reciprocating manner along the third direction.

Further, the pressing portion 161 is cylindrical, and the two connecting portions 162 connected to the two ends of the pressing portion 161 respectively extend into the corresponding sliding slots 122, so that when the movable end 133 is located at the adsorption position, the pressing portion 161 can roll back and forth along the first direction on the surface of one side of the flexible board 13 departing from the adsorption surface 132 along the second direction, so as to press the adsorption surface 132 of the flexible board 13 against the proton membrane, thereby ensuring the adsorption effect.

In this embodiment, the sliding groove 122 penetrates through the side plate 123 in the third direction, and the connecting portion 162 extends out of the side plate 123 from the sliding groove 122, so as to avoid the pressing member 16 from shifting during rolling on the flexible board 13 in the first direction, a limit rod may be provided on the side plate 123, and the limit rod may abut against the pressing portion 161 or the connecting portion 162.

In other embodiments, the sliding slot 122 may not penetrate through the side plates 123, the two sliding slots 122 are respectively opened on the sides of the two side plates 123 facing each other, and the connecting portion 162 of the pressing member 16 extends into the sliding slot 122. In this way, it is ensured that the pressure member 16 rolls in the first direction without shifting during rolling.

It should be explained that, the above-mentioned setting of the limiting rod or the opening of the sliding slot 122 that does not penetrate through the side plate 123 needs to have a gap with the pressing member 16, and the gap can enable the pressing member 16 to roll, and can also avoid the pressing member 16 from shifting in the rolling process.

In some embodiments, the film tearing apparatus further comprises an elastic member 17, one end of the elastic member 17 and the fixed end 131 are connected to the same end of the bracket 12, and the other end of the elastic member 17 is connected to the pressing member 16 for providing an elastic force for moving the pressing member 16 away from the fixed end 131 in the first direction.

Therefore, the elastic member 17 can also limit the movement of the pressing member 16 to a certain extent, and prevent the pressing member 16 from moving freely.

Further, the number of the elastic members 17 is two, the two elastic members 17 are arranged at intervals along the third direction, and one end of each elastic member 17 is connected to the end of the end plate 125, and the other end is connected to the connecting portion 162.

In addition, by providing two springs with the same spring force coefficient, the two connecting portions 162 at the two ends of the rolling portion are ensured to be stressed equally, thereby ensuring that the pressing member 16 does not deviate during reciprocating movement. Moreover, by providing two springs, the pressing member 16 can be ensured to reciprocate along the first direction even if no limit rod or no sliding groove 122 penetrating the side plate 123 is provided.

In some embodiments, the fixing end 131 is rotatably coupled to the bracket 12 about a first rotation axis extending in the third direction. Thus, compared with the fixing end 131 fixedly connected to the bracket 12, the fixing end 131 can be rotatably connected to the bracket 12 for convenient adjustment.

It should be noted that the fixed end 131 is relatively fixedly connected to the bracket 12, which means that no relative position occurs between the fixed end 131 and the bracket 12, and the fixed end 131 may be fixedly connected to the bracket 12 or rotatably connected to the bracket 12 around the first rotation axis, as described above.

It should be noted simultaneously that, when the movable end 133 is located the adsorption position, in order to ensure that the adsorption surface 132 is closely attached to the proton membrane, the adsorption surface 132 is parallel to the first direction, that is, the flexible board 13 is usually in a tiled state, and bending does not occur, and the movable end 133 is pulled away from the vacuum jig plate, the proton membrane is adsorbed on the adsorption surface 132 in the process, in order to avoid the flexible board 13 to be too bent, it needs to ensure that the flexible board 13 is tightened in the pulling process, the fixed end 131 is rotationally connected to the support 12, and the position where the flexible board 13 is close to the fixed end 131 can also be avoided from being too bent.

The negative pressure means communicates with one end of the plurality of connection passages, and negative pressure can be generated in the plurality of adsorption holes 134, thereby adsorbing the proton membrane.

Further, a plurality of absorption holes 134 equally divide into the multiunit, and multiunit absorption hole 134 arranges along the first direction interval, and a plurality of absorption holes 134 of each group arrange along the third direction interval, and a plurality of linking channel extend along the third direction lengthwise, and each linking channel communicates with a set of absorption hole 134 that corresponds. Specifically, one end of each connection passage penetrates through one side of the flexible board 13 in the third direction to communicate with the negative pressure device.

The pressing member 16 rolls toward the fixed end 131 along the first direction, and the plural sets of adsorption holes 134 are sequentially pressed on the proton membrane during the rolling process, while the adsorption holes 134 at the positions not pressed by the pressing member 16 may not be tightly attached to the proton membrane, and if all the adsorption holes 134 are communicated, the adsorption force of all the adsorption holes 134 is insufficient.

In practical application, the film tearing driving member 20 is a cylinder, a body of the cylinder is connected to the connecting plate 121, and a telescopic end of the cylinder is connected to the movable end 133.

As described above, the flexible board 13 has flexibility, even if the movable end 133 is located at the adsorption position, the movable end 133 and the fixed end 131 are arranged at intervals along the first direction, and the flexible board 13 is in a flat state, the movable end 133 can still move back and forth along the second direction within a certain range, and only the farther the movable end 133 is away from the adsorption position along the second direction, the greater the pulling force applied to the flexible board 13 is, i.e., the tighter the flexible board 13 is.

In some embodiments, tear film drive 20 drives movable end 133 to reciprocate in the second direction, and the maximum angle of rotation of flexible sheet 13 about the first axis of rotation during reciprocation of movable end 133 is 120 °. That is, when the movable end 133 is located at the absorption position, the flexible board 13 is in a horizontal state, the film tearing driving element 20 drives the movable end 133 to move upwards, and when the movable end 133 moves upwards to the highest position, the included angle between the flexible board 13 and the horizontal plane is 60 degrees.

In addition, the movable end 133 of the flexible board 13 can be rotatably connected to the connecting member 21 around an axis in the same manner as the fixed end 131 is rotatably connected to the bracket 12.
