The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1, the present embodiment provides a film tearing apparatus for separating an upper film and a lower film of a thin film. Alternatively, the film may be a CVL film or other film material requiring a tear film.
The film tearing device comprises an upper film lifting component 1, a film absorbing component 2, a film twisting component and a lower pulling film component 4. The upper film lifting assembly 1 is used for adsorbing and fixing the middle part of the upper film. The membrane absorbing assembly 2 is positioned below the upper membrane lifting assembly 1 and comprises a middle absorbing plate 201 used for absorbing and fixing the middle part of the lower membrane, a fixing support 202 fixedly arranged below the middle absorbing plate 201 and an end absorbing plate 203 used for absorbing and fixing the end part of the lower membrane. The membrane rubbing assembly is located between the middle suction plate 201 and the end suction plate 203, and is used for rubbing the upper membrane in the horizontal direction, and because the end position of the upper membrane is not fixed, the membrane rubbing assembly is displaced relative to the lower membrane during repeated rubbing, and finally the end position of the upper membrane is separated from the end position of the lower membrane. The pull-down membrane assembly 4 is used for driving the end suction plate 203 to move up and down so as to pull down the lower membrane after the end separation, and further realize the membrane tearing operation of the subsequent membrane section.
In this embodiment, the upper film stripping assembly 1 includes an upper suction plate 101 for adsorbing the upper film, a first linear driving mechanism 102 for driving the upper suction plate 101 to reciprocate up and down along a vertical direction, and a second linear driving mechanism 103 for driving the upper suction plate 101 to reciprocate back and forth along a horizontal direction.
It can be understood that the first linear driving mechanism 102 drives the upper suction plate 101 to move downwards to be attached to the film, so as to adsorb the upper film, and when the lower film is pulled downwards by the lower film pulling assembly 4, the second linear driving mechanism 103 drives the upper suction plate 101 to move forwards, so that the upper film after being torn is conveyed forwards.
In this embodiment, the film rolling assembly includes an upper film rolling mechanism and a lower film rolling mechanism. Referring to fig. 2, the upper film twisting mechanism includes an upper twisting roller 301, a third linear driving mechanism 302 for driving the upper twisting roller 301 to reciprocate along the vertical direction, and a fourth linear driving mechanism 303 for driving the upper twisting roller 301 to reciprocate along the horizontal direction. The lower film rolling mechanism comprises a lower rolling roller 305 and a fifth linear driving mechanism 306 for driving the lower rolling roller 305 to reciprocate along the vertical direction.
Specifically, at the beginning, the film is located between the upper rubbing roller 301 and the lower rubbing roller 305, the third linear driving mechanism 302 drives the upper rubbing roller 301 downwards, the fifth linear driving mechanism 306 drives the lower rubbing roller 305 upwards, and the lower rubbing roller 305 and the upper rubbing roller 301 can clamp the film; then, the fourth linear driving mechanism 303 drives the upper rubbing roller 301 to repeatedly move back and forth along the horizontal direction, which is equivalent to repeatedly rubbing the end of the upper layer film, and finally causes the end position of the upper layer film to be separated from the end position of the lower layer film.
Optionally, in order to improve the maximum static friction between the rubbing roller and the film and further improve the rubbing strength, the surfaces of the upper rubbing roller 301 and the lower rubbing roller 305 are both coated with an encapsulating layer.
Optionally, the upper film rubbing mechanism is further provided with an upper locking structure 304 for locking the upper rubbing roller 301, and the lower film rubbing mechanism is further provided with a lower locking structure for locking the lower rubbing roller 305. Generally, the upper locking structure 304 locks the upper rubbing roller 301, and the upper rubbing roller 301 cannot rotate; the lower locking structure locks the lower rubbing roller 305, and the lower rubbing roller 305 cannot rotate, so that the rubbing strength of the two rubbing rollers to the film is improved. When the kneading position of the upper kneading roller 301 is seriously worn or dirty, the upper locking structure 304 can be opened, and the upper kneading roller 301 is rotated by a certain angle and then locked, so that the utilization rate of the upper kneading roller 301 is improved, and the service life of the upper kneading roller 301 is prolonged. Similarly, the lower locking structure can improve the utilization rate of the lower rubbing roller 305 and prolong the service life of the lower rubbing roller 305.
In this embodiment, the upper locking structure 304 and the lower locking structure may be a clamp with a wrench, a plug inserted into a side surface of the rubbing roller, a ratchet coaxial with the rubbing roller, or a brake dial similar to a brake pad of a universal wheel provided on the rubbing roller, or may be a cylinder directly driving two clamping pieces to clamp the upper rubbing roller 301 or the lower rubbing roller 305 to achieve a locking function. The specific locking structure is not the focus of the present application and is not described in detail.
Referring to fig. 3, the lower membrane module 4 includes a lifting platform 401, a sixth linear driving mechanism 402, a fixed clamping block 403, a movable clamping plate 404, a seventh linear driving mechanism 405, a horizontal sliding plate 406, and an eighth linear driving mechanism 407.
The end suction plate 203 is fixed to the lifting platform 401. The sixth linear driving mechanism 402 is used for driving the lifting platform 401 to reciprocate along the vertical direction. The fixed clamp block 403 is located on one side of the end suction plate 203 away from the membrane twisting assembly.

The seventh linear driving mechanism 405 is used to drive the movable clamping plate 404 to move closer to or away from the fixed clamping block 403 along the vertical direction. The fixed clamp block 403 is fixed above the horizontal sliding plate 406. The eighth linear driving mechanism 407 is configured to drive the horizontal sliding plate 406 to slide along the horizontal direction relative to the lifting platform 401.
Specifically, initially, horizontal slide 406 is located at the end farther from the film; when the membrane twisting assembly separates the upper membrane from the lower membrane, the eighth linear driving mechanism 407 drives the horizontal sliding plate 406 to drive the fixed clamping block 403 and the movable clamping block to slide together to be close to the end of the lower membrane, so that the end of the lower membrane is inserted between the fixed clamping block 403 and the movable clamping plate 404; then, the seventh linear driving mechanism 405 drives the movable clamping plate 404 to move upwards, and the end part of the lower layer film is clamped by matching with the fixed clamping block 403, so that the lower layer film is prevented from being separated from the end part suction plate 203 in the process of pull-down; finally, the sixth linear driving mechanism 402 drives the lifting platform 401 to move downwards, so that the film tearing operation of the lower layer film can be realized.
The linear driving mechanisms in this embodiment may be air cylinders, hydraulic cylinders, or motor screw assemblies, and the present embodiment is not limited thereto.
