Description

Technical Field

[0001] The utility model relates to the technical field of film-tearing equipment, in particular to a film-tearing device for a backing film. Background Art

[0002] At present, it is easy to automatically tear off the release film for rolls of adhesive-backed stickers. However, for hard adhesive-backed stickers supplied in the form of sheets, such as display stickers, each sheet has several display stickers. During the current operation, they are manually torn off the release paper or film one by one and attached to the equipment. The processing efficiency is very low and the labor cost is high.

[0003] For example, a Chinese utility model patent with authorization announcement number CN209454332U discloses a film tearing device, which is equipped with a suction cup assembly and a manipulator, so that the suction cup assembly can adsorb the flange of the release film of the VHB film on the workbench, and the manipulator grabs the back film of the VHB film. At this time, the suction cup assembly adsorbs the flange to quickly separate the release film and the back film, thereby achieving film tearing, shortening the time for film tearing, and improving production efficiency.

[0004] However, when the device is still in use, each time the film is to be torn off, the film to be torn off needs to be transferred to the workbench for fixation by an external robot. After the film is torn off, the processed film needs to be transferred away by the robot before a new film can be placed for fixation. The processing flow is not coherent enough, which reduces the processing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figures 1 to 6 , a device for tearing film from a backing film, comprising: a processing table 1, a material transport mounting seat 11 is installed on the upper end of the processing table 1, a material transport disc 13 is also rotatably installed on the upper end of the material transport mounting seat 11, and a material transport motor 12 for driving the material transport disc 13 to rotate is also installed on the material transport mounting seat 11; a film tearing assembly, comprising a moving mechanism 3 installed on the processing table 1 and a clamping mechanism 4 installed on the moving mechanism 3, which is used to tear off the protective film on the film; a material transport mechanism 2 is provided with multiple groups, all of which are installed on the material transport disc 13, and are used to transfer the film to the position of the film tearing assembly. In order to improve the film tearing efficiency, the material transport mechanism 2 is provided with at least three groups. In order to facilitate the recovery of the torn protective film, a material guide seat 15 is embedded in the position of the film tearing assembly corresponding to the upper end of the processing table 1, and a recovery frame 16 is placed at the position of the material guide seat 15 corresponding to the lower end of the processing table 1.

[0025] The working principle of the utility model is as follows: during specific use, one group of material transporting mechanisms 2 transfers the film to the film tearing assembly position, and then, the moving mechanism 3 drives the clamping mechanism 4 to move to the film position, and then, the flange of the protective film on the outer side of the film is clamped by the clamping mechanism 4, and then, the moving mechanism 3 drives the clamping mechanism 4 to move, so that the protective film on the film can be torn off, and then, the moving mechanism 3 drives the clamping mechanism 4 to move to the recycling frame 16 position, and the clamping mechanism 16 releases the protective film, so that the protective film can fall into the recycling frame 16 to complete the collection work, and at the same time, the unprocessed film is fixed to another material transporting mechanism 2, and then, the material transporting motor 12 drives the material transporting disc 13 to rotate, so that the untorn film is transferred to the film tearing assembly position for easy film tearing, and the film that has been torn is transferred to the unloading position, and then the film is taken off, and at the same time, the film is fixed on the other empty material transporting mechanism 2, and so on and so forth, which can effectively improve the continuity of the film tearing work, reduce the waiting time of the film tearing process, thereby improving the film tearing efficiency, and can better meet the use requirements.

[0026] As a further solution, the material transport mechanism 2 includes a material transport seat 21 installed on the material transport plate 13, a material transport slide rail 22 is installed on the material transport seat 21, a material transport slide 23 is slidably installed on the material transport slide rail 22, a material transport suction cup 25 is installed on the material transport slide 23, and a material transport electric push rod 24 is also installed on the material transport seat 21, and the telescopic end of the material transport electric push rod 24 is fixedly connected to the end of the material transport slide 23.

[0027] In this embodiment, the material transporting suction cup 25 is a vacuum suction cup.

[0028] The working principle of the material transport mechanism 2 is: when transporting materials, first the material transport slide 23 is pushed to move by the material transport electric push rod 24, so that the material transport suction cup 25 is close to the film. After the material transport suction cup 25 contacts the film, the film is sucked by the material transport suction cup 25 to complete the fixation of the film. Then, the material transport motor 12 drives the material transport disc 13 to rotate, thereby realizing the rotation of the film and completing the material transport work.

[0029] As a further solution, the mobile mechanism 3 includes a mobile frame 31 installed on the processing table 1, a lateral movement module 32 is installed on the mobile frame 31, a lateral movement slide 33 is slidably installed on the lateral movement module 32, a lifting module 34 is installed on the lateral movement slide 33, and a lifting slide 35 is slidably installed on the lifting module 34; the lateral movement module 32 and the lifting module 34 are both existing mature technologies;

[0030] The clamping mechanism 4 includes a clamping support plate 42 installed on the lifting slide 35, and a shifting cylinder 43 is also installed on the lifting slide 35. A paddle assembly 44 is fixed to the telescopic end of the paddle cylinder 43. A pneumatic clamp 41 is also installed on the side of the lifting slide 35. The claws of the pneumatic clamp 41 are provided with anti-slip teeth 411. In order to facilitate the flange at the end of the film to be shifted into the pneumatic clamp 41, the paddle assembly 44 includes a paddle connecting seat 441 installed on the telescopic end of the paddle cylinder 43. The paddle connecting seat 441 is L-shaped, and a paddle rod 442 extends from the paddle connecting seat 441.

[0031] The working principle of the film tearing assembly is: the transverse moving module 32 drives the transverse moving slide 32 to move forward and backward, thereby realizing the forward and backward movement of the lifting module 34, and the lifting slide 35 is driven up and down by the lifting module 34, so as to realize the height adjustment of the clamping mechanism 4. After the clamping mechanism 4 moves to the appropriate position, the cylinder 43 is driven to drive the lever 42 to move, so that the flange of the protective film on the outside of the film is bent around the edge of the clamping support plate 42. After the flange is extended into the pneumatic clamp 41, the flange is clamped by the pneumatic clamp 41. Subsequently, the clamping mechanism 4 is driven to move by the moving mechanism 3, so that the protective film can be torn off from the film, and then the film is transferred to the top of the recycling frame 16, and the pneumatic clamp 41 releases the flange. At this time, the protective film can fall into the recycling frame 16 to complete the collection work.

[0032] In order to facilitate the determination of the film position, a 3D camera 14 is also installed on the processing table 1. In this embodiment, the 3D camera 14 is an existing mature technology. Through the 3D camera 14, the film position is conveniently determined, so that the moving mechanism 3 drives the clamping mechanism 4 to move to a suitable position for film tearing.
