DETAILED DESCRIPTION

[0029] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0030] like Figures 1-6As shown, the present invention provides a multi-angle fully automatic film tearing device, which can meet the needs of long-distance and multi-angle film or release paper tearing. The present invention is illustrated by film tearing. The film tearing device of the present invention includes a support base 100, and a rotating platform mechanism 200 for placing materials is provided at one end of the support base 100. The rotating platform mechanism 200 is used to drive the material to rotate. The rotating platform mechanism 200 includes a rotary drive motor 201 and a rotating plate 202 connected to the driving end of the rotary drive motor 201. The driving end of the rotary drive motor 201 is arranged perpendicular to the direction of the support base 100. In order to install the rotating platform mechanism 200, a mounting platform is fixed to the side of one end of the support base 100. The mounting platform includes a vertical plate 1011 and a mounting bin 1012 fixed to the top surface of the vertical plate 1011. In order to facilitate the placement of materials and facilitate the approach of the clamping jaw assembly 400 described below, the top surface of the mounting bin 1012 and the side facing the clamping jaw assembly 400 are both open. The vertical plate 1011 is fixed to the side of one end of the support base 100, and the mounting chamber 1012 is positioned above the support base 100. The fixed end of the rotary drive motor 201 is connected to the vertical plate 1011, while its driving end vertically passes through the bottom surface of the mounting chamber 1012 and then rotates to connect to the rotating plate 202. The material to be removed is placed on the rotating plate 202, and the rotary drive motor 201 drives the rotating plate 202 and the material to rotate in the plane. The shape and size of the rotating plate 202 can be set according to the shape and size of the material. In this utility model, the material is a mobile phone, and the rotating plate 202 is an elongated rectangle.

[0031] In addition, a material arrival sensor 701 is provided on the installation bin 1012 for detecting whether there is material placed on the rotating plate 202 .

[0032] Preferably, to prevent the material from falling or moving, the rotating plate 202 is provided with a plurality of vacuum suction cups 2021, each of which is connected to a vacuum generator (not shown) via a vacuum line (not shown). The plurality of vacuum suction cups 2021 are arranged along the side of the rotating plate 202 to ensure that the material is evenly stressed and is not easily moved or dropped.

[0033] As one of the embodiments, the rotating platform mechanism in the utility model can independently drive the material to be torn off to rotate stably. It can be used alone in conjunction with the robot in the prior art. The material is pulled to tear the film while rotating, thereby realizing the tearing action of the film material at multiple angles and long distances.

[0034] As another embodiment, a suitable avoidance opening 203 is provided on the side of the rotating plate 202 facing the clamping jaw assembly 400 to allow the clamping jaw assembly 400 to approach the rotating plate 202 to facilitate clamping the film material of the upper material.

[0035] A linear motion module 300 is provided along the length of the upper surface of the support base 100 and is located below the mounting compartment 1012. The driving end of the linear motion module 300 is connected to a slider 301, to which a clamping jaw assembly 400 is attached. The clamping jaw assembly 400 is located near the escape opening 203. The linear motion module 300 drives the clamping jaw assembly 400 toward or away from the rotating plate 202. The linear motion module 300 of the present invention is a KK linear motion module, but is not limited thereto. Other existing linear motion modules, such as a lead screw linear motion module, may also be used.

[0036] The clamp assembly 400 includes a clamp cylinder 401 with a fixed end fixed to the slider 301 and two clamp arms 402 positioned opposite to the drive end of the clamp cylinder 401. The clamp cylinder 401 drives the two clamp arms 402 toward or away from each other to clamp or release the film material on the material. The clamp cylinder 401 of the present invention is a finger cylinder. In addition, a film tearing sensor 702 is provided on the mounting bin 1012 near the two clamp arms 402 to detect whether the two clamp arms 402 have clamped the film material on the rotating plate 202.

[0037] Preferably, in order to better clamp the film material, a serrated surface 4021 is provided on the surface of one clamping arm 402 facing the other clamping arm 402 , and a rubber coating 4022 is provided on the surface of the other clamping arm 402 facing the serrated surface 4021 .

[0038] In addition, the linear motion module 300 is provided with a plurality of photoelectric switches 302 for controlling the movement and stopping stroke of the clamping jaw assembly 400. Specifically, a photoelectric switch 302 is provided on the linear motion module 300 near the rotating plate 202, and a photoelectric switch 302 is provided on the side of the linear motion module 300 away from the rotating plate 202.

[0039] A film guide assembly 500 is located on the support base 100, between the rotating plate 202 and the clamping jaw assembly 400. The film guide assembly 500 comprises a lift cylinder 501 and two guide rods 502. The fixed end of the lift cylinder 501 is connected to a side of the support base 100 and is located on the same side as the rotary drive motor 201. The driving end of the lift cylinder 501 is positioned perpendicular to the support base 100 and is connected to the two guide rods 502. The two guide rods 502 are arranged parallel and spaced apart along the width of the support base 100. The lift cylinder 501 drives the two guide rods 502 to rise and fall in a direction perpendicular to the support base 100.

[0040] When the clamping jaw assembly 400 moves toward the rotating plate 202, the two guide rods 502 are located below the two clamping jaw arms 402, so that the two clamping jaw arms 402 are close to the rotating plate 202. When the clamping jaw assembly 400 clamps the film material on the material and moves it away from the rotating plate 202, after the film material passes through the middle of the two guide rods 502, the lifting cylinder 501 drives the two guide rods 502 to rise. At this time, no matter whether the rotary drive motor 201 is rotating forward or reverse, the film material can form a wrap angle with one of the guide rods 502, so that the film material has a guiding function when it moves away from the material surface with the clamping jaw assembly 400, thereby preventing the film material from flying everywhere.

[0041] To recover the torn film material, the support base 100 is also equipped with a film recovery mechanism 600. This mechanism comprises a film suction trough 601, a pneumatic conveyor 603, and a recovery box 604. The film suction trough 601 is positioned parallel to the linear motion module 300 and is fixed to one side of the support base 100, coexisting with the lifting cylinder 501. Two clamping arms 402 are positioned above the film suction trough 601.

[0042] The film suction groove 601 is a long rectangular groove with side guards on both sides along its length and on the end away from the guide rod 502. The end close to the guide rod 502 and the top surface are both provided with openings to facilitate the passage of film materials. A film suction through hole 602 is also provided at the middle end. A pneumatic conveyor 603 providing suction is connected below the film suction through hole 602, and a recovery box 604 is connected below the pneumatic conveyor 603.

[0043] The operation process and principle of this utility model are as follows:

[0044] S1: Place the material to be film-teared onto the vacuum suction cup 2021 on the rotating plate 202. In actual production, the end face of the film material on the material surface generally has a small ear for easy gripping during film tearing. To facilitate film tearing, the small ear of the film material is placed at the avoidance opening 203 of the rotating plate 202. When the material arrival sensor 701 detects the arrival of the material, the linear motion module 300 drives the two clamping arms 402 to move to the avoidance opening 203 of the rotating plate 202 and below the small ear of the film material. The clamping cylinder 401 drives the two clamping arms 402 toward each other until the film material is clamped.

[0045] S2: The film tearing sensor 702 senses that the two clamping arms 402 have clamped the film material, and the rotating platform mechanism 200 and the linear motion module 300 start to operate synchronously. That is, while the rotating plate 202 drives the material to rotate, the two clamping arms 402 move the film material away from the material surface, satisfying the film tearing and achieving the change of film tearing length and multi-angle.

[0046] S3, the two clamping arms 402 move the film material away from the material surface. When the film material passes the guide rod 502, the lifting cylinder 501 drives the two guide rods 502 to rise. At this time, the film material rests on the surface of one of the guide rods 502, forming a wrap angle with it to stabilize the trajectory of the film material as it moves with the two clamping arms 402 and prevent it from flying away.

[0047] S4, the two clamping arms 402 continue to move the film material along the film suction groove 601 away from the material surface. When they move to the film suction through hole 602, the pneumatic conveyor 603 is started. At this time, a downward suction force is generated at the film suction through hole 602. At this time, the suction force acts on the film material. Combined with the pulling force of the two clamping arms 402 on the film material and the supporting and guiding force of the guide rod 502 on the film material, the film material can be prevented from being deformed due to the continuous pulling force during the film tearing process, which ultimately affects the film tearing effect.

[0048] S5, when the two clamping arms 402 move the film material to the preset position away from the material surface, the film tearing action is completed, the rotating platform mechanism 200 and the linear moving module 300 stop running synchronously. At the same time, the film material located in the film suction groove 601 is sucked into the recovery box 604 through the film suction hole 602 under the action of the pneumatic conveyor 603, completing the film material recovery action.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
