DETAILED DESCRIPTION

[0028] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0029] As Figure 1 shown, the present application provides a film tearing device, comprising a rack 1, a feeding assembly 2, a film tearing assembly 3, a film recycling assembly 4 and a control assembly, the rack 1 is a supporting frame of the whole device, the feeding assembly 2 is installed on the rack 1 and is used to transport green bodies with base films to a film tearing work position, to ensure accurate positioning of the green bodies and to provide a basis for subsequent film tearing operation; the film tearing assembly 3 is drivingly connected to the rack 1 and is located above the film tearing work position, reciprocates between the film tearing work position and a film recycling position along a first direction (such as Figure 1 or Figure 2 the arrow A direction shown) to realize peeling and recycling of the base film; the film recycling assembly 4 is installed on the rack 1 and is located at the film recycling position to recycle the peeled base film; the control assembly is electrically connected with the feeding assembly 2, the film tearing assembly 3 and the film recycling assembly 4 to coordinate operation of the assemblies and realize automatic control.

[0030] Based on the above structure, the feeding assembly 2 transports the green bodies with base films to the film tearing work position, the film tearing assembly 3 moves along the first direction to separate the base film from the green bodies, at this time the film recycling assembly 4 fixes the peeled base film, while the film tearing assembly 3 returns along the first direction to separate from the base film, then the film recycling assembly 4 releases the base film to make it fall down for recycling. Through mutual cooperation of the feeding assembly 2, the film tearing assembly 3 and the film recycling assembly 4, the present embodiment can realize peeling of the base film from the green bodies and recycling of the base film, greatly reducing the probability of peeling failure and improving the production speed due to high degree of automation of the peeling and recycling process.

[0031] AsFigure 1 and Figure 2 As shown, the feeding assembly 2 includes a support platform 21, a rotating structure 22, and a moving structure 23. The support platform 21 is used to place the green blank with a base film. The output end of the rotating structure 22 is connected to the support platform 21 to drive the support platform 21 to rotate, thereby adjusting the angle of the green blank on the support platform 21 so as to achieve a suitable working angle during processing, increasing the flexibility and accuracy of operation, and making the processing more efficient. The moving structure 23 is fixed to the frame 1, and the output end of the moving structure 23 is connected to the rotating structure 22 to drive the support platform 21 to perform lifting and lowering movements, realizing the movement and replacement of the green blank with a base film.

[0032] This embodiment, through the coordinated operation of the support platform 21, the rotating structure 22, and the moving structure 23, can achieve functions such as green blank transfer and angle adjustment, thereby achieving more efficient operation. It should be noted that the moving structure 23 and the rotating structure 22 in this embodiment can be driven by components such as servo motors and cylinders, and are not specifically limited thereto. Furthermore, a bracket can be provided between the moving structure 23 and the rotating structure 22 for installation and connection.

[0033] Furthermore, the feeding assembly 2 also includes a locking structure 24, which is fixed to the frame 1 and can be locked in place with the support platform 21. This ensures that the position of the support platform 21 remains stable during peeling operations (such as tearing the base film off the green body). When the locking structure 24 is locked in place with the support platform 21, one diagonal of the support platform 21 is parallel to the first direction. At this time, one diagonal of the green body with the base film is also parallel to the first direction. Under the above configuration, the film tearing assembly 3 can start tearing the film from one corner of the rectangular base film, reducing the difficulty of tearing the film and making it easier to lift the base film, avoiding incomplete film tearing, film adhesion, etc., thereby improving work efficiency and quality.

[0034] It should be noted that the locking structure 24 in this embodiment includes a locking component and a driving component structure. The locking component has a locking notch. When working, the locking component can be driven to the bottom of the support platform 21 by a driving component structure such as a servo motor or cylinder. It is locked to the bottom of the support platform 21 by the locking notch, which restricts its rotation and lifting, thereby achieving locking. When it is necessary to release, the locking component can be driven away by the driving component structure.

[0035] like Figure 1 and Figure 2As shown, the film tearing assembly 3 comprises a slide rail 31, a first driving component 32, an adhering wheel 33, a first clamping member 34 and a lever connecting structure 35; the slide rail 31 is installed on the frame 1, and the slide rail 31 is arranged in parallel along a first direction to provide a movement track for the lever connecting structure 35, one end of the lever connecting structure 35 is slidably connected to the slide rail 31, the adhering wheel 33 is rotatably connected to the other end of the lever connecting structure 35 to start the film tearing process by rotating and contacting and adhering the base film, the first clamping member 34 is movably connected to the lever connecting structure 35, and the first clamping member 34 can be clamped with the adhering wheel 33, when the adhering wheel 33 lifts the base film, the first clamping member 34 can be clamped with the adhering wheel 33 to increase the pulling force on the base film and ensure that the film is stably torn, the first driving component 32 is installed on the frame 1 and connected to the lever connecting structure 35 to drive the lever connecting structure 35 to reciprocate on the slide rail 31 along the first direction, thereby realizing the film tearing operation.

[0036] It can be understood that even if the adhering wheel 33 has insufficient adhesion, the base film can be torn off with the cooperation of the first clamping member 34, reducing the possibility of peeling failure.

[0037] Referring to Figure 1 , Figure 2 and Figure 4 together, the slide rail 31 has a protruding portion 311, and the lever connecting structure 35 comprises a fixing member 351, a spring member 352, a pull rod 353, a lever member 354, a force applying rod 355, a mounting rod 356 and a pulley 357, the fixing member 351 is drivingly connected to the first driving component 32, one end of the mounting rod 356 is hingedly connected to the fixing member 351, the other end of the mounting rod 356 is hingedly connected to one end of the pull rod 353, the other end of the pull rod 353 is hingedly connected to one end of the lever member 354, the other end of the lever member 354 is hingedly connected to one end of the force applying rod 355 and one end of the spring member 352, a first fulcrum 358 is arranged between the two ends of the lever member 354 to allow the lever member 354 to rotate, and the lever member 354 is connected to the fixing member 351 through the first fulcrum 358, the other end of the spring member 352 is fixedly connected to the fixing member 351 to provide a restoring force to help the first clamping member 34 switch between the clamping and releasing states, the other end of the force applying rod 355 is hingedly connected to the first clamping member 34, the pulley 357 is installed on the other end of the mounting rod 356, and the pulley 357 cooperates with the slide rail 31.

[0038] The embodiment forms a rotation center at a specific point (such as the first fulcrum 358) through the mutual articulation of the fixing member 351, the spring member 352, the pull rod 353, the lever member 354, the force applying rod 355, the mounting rod 356, and the pulley 357, so that the entire structure can respond to the corresponding mechanical movement when the pulley 357 passes the protrusion 311 matched therewith. When the first driving member 32 works, it drives the lever connecting structure 35 to move along the slide rail 31, and when the lever connecting structure 35 moves to the protrusion 311 of the slide rail 31, the pulley 357 is lifted, and then one end of the lever member 354 is pulled by the pull rod 353, and then the other end of the lever member 354 is forced to the force applying rod 355 to apply a pushing force to the first clamping member 34 through the force applying rod 355 to keep the first clamping member 34 in the loosened state. When moving to the flat part of the slide rail 31, the spring member 352 pulls the lever member 354 because there is no external force acting on the pulley 357, so that the first clamping member 34 rotates back to the clamping position. The first driving member 32 of the embodiment can be a servo motor, a cylinder, or other driving member structure, which is not particularly limited here.

[0039] It can be understood that by adjusting the position of the protrusion 311, the loosened position of the first clamping member 34 can be preset. In some embodiments, the loosening and tightening activities of the first clamping member 34 can also be controlled by motors, cylinders, and other components.

[0040] Further, the first clamping member 34 includes a torque portion 341 and a clamping portion 342 for clamping cooperation with the adhesion wheel 33, one end of the torque portion 341 is articulated with the other end of the force applying rod 355, the other end is connected with the clamping portion 342 to transmit the force from the force applying rod 355 to the clamping portion 342 to realize the clamping or loosening action of the clamping portion 342. It can be understood that the clamping portion 342 is used to directly cooperate with the adhesion wheel 33 and complete the clamping operation; the second fulcrum 343 is arranged between the clamping portion 342 and the torque portion 341, and the first clamping member 34 is connected with the fixing member 351 through the second fulcrum 343, and the clamping portion 342 and the torque portion 341 rotate around the second fulcrum 343.

[0041] When the force applying rod 355 applies force to the torque portion 341, the torque portion 341 converts this force into a force that promotes the rotation of the clamping portion 342 around the second fulcrum 343. According to the direction and size of the force, the clamping portion 342 can be driven to a position close to or away from the adhesion wheel 33, thereby realizing the clamping or releasing function. When it is necessary to clamp the adhesion wheel 33, the clamping portion 342 will be pushed to the adhesion wheel 33 under the action of the spring member 352, and the adhesion wheel 33 is firmly clamped by suitable pressure. When it is necessary to loosen the adhesion wheel 33, the force applying rod 355 will apply a force in the opposite direction to the torque portion 341, so that the clamping portion 342 rotates away from the adhesion wheel 33 around the second fulcrum 343, and the clamping state is released.

[0042] AsFigures 1 to 3 As shown, the film recycling assembly 4 comprises a recycling platform 41, a first clamping structure 42, a rotating member 43 and a second driving component 44. The recycling platform 41 is fixedly connected to the rack 1 and used to carry the peeled-off substrate film. The first clamping structure 42 is installed on the rotating member 43 and used to clamp and release the substrate film. The second driving component 44 is fixedly connected to the rack 1 and has an output end fixedly connected to the rotating member 43 to drive the first clamping structure 42 to rotate back and forth between a releasing position (a position not clamping the substrate film) and a clamping position (a position clamping the substrate film).

[0043] When the film stripping assembly 3 works, it will strip the substrate film from the green body and move to the recycling platform 41. Then, the first clamping structure 42 in the film recycling assembly 4 will be driven by the second driving component 44 to rotate to the clamping position through the rotating member 43 to clamp the peeled-off substrate film. With the film stripping assembly 3 moving reversely along the first direction, the substrate film is removed from the adhesive wheel 33, and then the first clamping assembly releases the substrate film. The second driving component 44 in the embodiment can be a servo motor, a pneumatic cylinder or other driving component structure, which is not particularly limited here.

[0044] Further, the first clamping structure 42 comprises a second clamping member 421 and a third driving component 422. The second clamping member 421 and the third driving component 422 are installed on the rotating member 43 to move with the rotating member 43 to adjust the clamping position. The output end of the second clamping member 421 and the third driving component 422 are fixedly connected, and the third driving component 422 can directly drive the second clamping member 421 to open and close when the third driving component 422 is started.

[0045] The third driving component 422 in the embodiment can be a servo motor, a pneumatic cylinder or other driving component structure, which is not particularly limited here.

[0046] Further, the horizontal plane where the recycling platform 41 is located is higher than the horizontal plane where the carrying platform 21 is located, which is beneficial to lay the peeled-off substrate film flat on the recycling platform 41, so that the second clamping member 421 can easily press the substrate film to remove it from the adhesive wheel 33.

[0047] Further, the film recycling assembly 4 further comprises a second clamping structure 45. The second clamping structure 45 comprises a third clamping member 451 and a fourth driving component 452. The fourth driving component 452 is installed on the recycling platform 41, and the output end of the fourth driving component 452 is connected with the third clamping member 451 to provide power for the third clamping member 451 to complete the clamping and releasing actions. By adding the second clamping structure 45, the clamping force on the substrate film is increased, so that even if the adhesion of the adhesive wheel 33 is too large, the peeled-off substrate film can also be easily removed from the adhesive wheel 33.

[0048] The fourth driving component 452 of the present embodiment can be a driving member structure such as a servo motor, a cylinder, etc., which is not particularly limited herein.

[0049] The working process of the film tearing device is as follows: the feeding assembly 2 transports the green body with the base film to the film tearing position, the rotating component rotates the diagonal line of the bearing platform 21 to be parallel to the first direction, and the locking component locks the bearing platform 21. At this time, the starting position of the film tearing assembly 3 is the corner of the base film, which is easy to lift.

[0050] The first driving component 32 drives the lever connecting structure 35, the adhesive wheel 33 and the first clamping component 34 to move along the first direction. The adhesive wheel 33 adheres to the corner of the base film to separate it from the green body. When the separation reaches a certain position, under the combined action of the weight of the base film itself and the adhesion between the base film and the green body, the adhesion of the adhesive wheel 33 will be difficult to lift the base film. At this time, the first clamping component 34 clamps the base film under the action of the lever connecting structure 35. Under the combined action of the adhesion and the clamping force, the base film can be easily peeled off.

[0051] The first driving component 32 drives the lever connecting structure 35, the adhesive wheel 33 and the first clamping component 34 to move along the first direction. When the peeled base film reaches the recovery platform 41, the peeled base film will be flattened on the recovery platform 41 because the recovery platform 41 is higher than the bearing platform 21. At this time, the first clamping component 34 releases the adhesive wheel 33 under the action of the lever connecting structure 35. At this time, the second clamping component 421 is flush with the recovery platform 41. The second clamping component 421 and the third clamping component 451 clamp the peeled base film under the action of the third driving component 422 and the fourth driving component 452. Meanwhile, the first driving component 32 drives the lever connecting structure 35, the adhesive wheel 33 and the first clamping component 34 to return along the first direction, so as to separate the adhesive wheel 33 from the base film.

[0052] After the film tearing assembly 3 returns, the third clamping component 451 is released, the second driving component 44 drives the rotating component 43 to rotate, the second clamping component 421 and the third driving component 422 rotate the base film to below the recovery platform 41, and then the second clamping component 421 is released to make the base film fall down. In the present embodiment, a collection box can be arranged beside the film tearing device to collect the fallen base film.

[0053] Further, the feeding assembly 2 transports the green body with the base film peeled off away, and supplies a new green body with a base film. The film tearing assembly 3 returns to the initial position to start a new film tearing operation. The above process has high automation degree, saves labor, and can greatly improve the production efficiency and reduce the cost.

[0054] In conclusion, the embodiment of the utility model provides a kind of film tearing device, it is through the cooperation of feeding assembly 2, film tearing assembly 3 and film recycling assembly 4, substrate film can be peeled from green body, and the work of recycling substrate film is realized, greatly reduce the probability of peeling failure, and the degree of automation of peeling and recycling process is high, which is beneficial to improve production speed.

[0055] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled person in the art, without departing from the technical principle of the utility model, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the utility model.
