[0002] As a key piece of equipment in the precision manufacturing field, film-peeling devices have wide and indispensable applications in industries such as electronics, optics, automotive, and semiconductors. For complex product processing, protective films are often applied to protect the product surface. Currently, the removal of curved or irregularly shaped films is usually done manually, which can lead to scratches on the product surface due to uncontrollable human intervention.
[0003] In related technologies, there are automated film-tearing equipment. Most of these film-tearing equipment use adhesive tape to adhere the film layer to achieve the purpose of film tearing, or use electrostatic adsorption. However, when facing products with curvature, irregular shape, or flat surface, the above two film-tearing methods cannot adhere the protective film on the product surface well. During the tearing process, the film is prone to being torn due to the small contact area. Utility Model Content
[0004] The purpose of this invention is to provide a film-tearing device to solve the problems mentioned in the background art, such as the protective film being torn during the film-tearing operation and the need to reduce manual labor.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a film-tearing device for tearing off the protective film on the surface of a product conveyed by a feeding mechanism, comprising a base, wherein the feeding mechanism is disposed on the base and drives the product to be peeled to perform film-piercing and film-tearing operations sequentially; a film-piercing mechanism comprising a first pushing mechanism and a piercing needle; a second pushing mechanism disposed above the first pushing mechanism, wherein the piercing needle is disposed above the second pushing mechanism and is hinged to the second pushing mechanism; and a film-tearing mechanism comprising a first film-tearing gripper, the first film-tearing gripper being inverted L-shape, a second film-tearing gripper disposed below the horizontal section of the first film-tearing gripper, and a gap being left between the top surface of the second film-tearing gripper and the horizontal section of the first film-tearing gripper.
[0006] Preferably, the needle is fixed on the follower mechanism, the follower mechanism is hinged to the second push mechanism, and a spring is connected to the follower mechanism and the second push mechanism; when the spring contacts the product to be peeled, the needle is squeezed, causing the follower mechanism and the second push mechanism to swing, and the spring is in a stretched state.
[0007] Preferably, the first pushing mechanism is disposed in the base, driving the needle to adhere to the protective film and penetrate into the protective film.
[0008] Preferably, the film-piercing mechanism further includes a baffle disposed outside the first pushing component for fixing the film product to be peeled off.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides a technical solution: a film-tearing device for tearing off the protective film 3 on the surface of a product conveyed by a feeding mechanism 2. The device includes a base 1, with the feeding mechanism 2 mounted on the base 1. The feeding mechanism 2 drives the product to be peeled to sequentially perform film-piercing and film-tearing operations. The film-piercing mechanism includes a first pushing mechanism 4 and a piercing needle 6. A second pushing mechanism 5 is positioned above the first pushing mechanism 4, and the piercing needle 6 is positioned above the second pushing mechanism 5 and hinged to it. The film-tearing mechanism includes a first film-tearing gripper 7, which is inverted L-shaped. A second film-tearing gripper 8 is positioned below the horizontal section of the first film-tearing gripper 7, with a gap between the top surface of the second film-tearing gripper 8 and the horizontal section of the first film-tearing gripper 7.
[0022] The needle 6 is fixed on the follower mechanism 9, which is hinged to the second push mechanism 5, and a spring 10 is connected to the follower mechanism 9 and the second push mechanism 5. When the spring 10 contacts the product to be peeled, the needle 6 is squeezed, which causes the follower mechanism 9 and the second push mechanism 5 to swing, and the spring 10 is in a stretched state.
[0023] The first pushing mechanism 4 is disposed in the base 1, driving the needle 6 to adhere to the protective film 3 and pierce into the protective film 3. The second pushing mechanism 5 is disposed on the first pushing mechanism 4, driving the needle 6 to move laterally along the protective film 3, separating the protective film 3 on that side from the product.
[0024] As the piercing operation is completed, the needle pierces the protective film. When the first pushing mechanism resets, it can further drive the needle to separate the protective film from the product. When the second pushing mechanism resets, it can also cause a corner of the protective film to create an angle difference with the product.
[0025] The film-piercing mechanism also includes a baffle 11 disposed outside the first pushing component 4 for fixing the film product to be torn. The baffle 11 bears the deformation of the film product caused by the external force of the piercing needle driven by the first pushing mechanism 3, thus preventing the film product to be torn from deforming.
[0026] A horizontal moving component is provided on one side of the first film-tearing gripper 7 to drive the first film-tearing gripper 7 toward the product; the horizontal moving component includes a motor 12, a lead screw 13 and a connector 14; the motor 12 drives the lead screw 13 to rotate, one end of the connector 14 is sleeved on the lead screw 13 and threadedly connected to the lead screw 13, and the other end of the connector 14 is fixed to the first film-tearing gripper 7.
[0027] A vertical moving component is provided below the second film-tearing claw 8, which drives the second film-tearing claw 8 to move vertically.
[0028] The first film-tearing claw 7 is moved towards the product to be peeled by the horizontal moving component, and the first film-tearing claw 7 adheres to and presses against the product, so that the protective film on one side of the product is separated from the product itself. The vertical moving component can be a cylinder, which drives the second film-tearing claw 8 on the cylinder to move upward, so that the second film-tearing claw 8 and the first film-tearing claw 7 clamp the protective film located between the second film-tearing claw 8 and the first film-tearing claw 7. When the horizontal moving component and the vertical moving component are reset, the protective film is completely separated from the product, and the film-tearing operation is completed.
[0029] In this embodiment, the positions of the film-piercing mechanism and the film-tearing mechanism can be adjusted according to the position of the protective film in the product to be peeled.
[0030] In this embodiment, an anti-slip layer 15 is provided on the bottom surface of the horizontal section of the first tearing gripper 7.
[0031] In this embodiment, the top surface of the second film-tearing claw 8 is provided with multiple protrusions 16. This allows for better clamping of the protective film, enabling the protective film to separate from the product.
[0032] The second film-tearing gripper 8 has an air blowing hole 17 on the side near the product to be peeled. Air is blown while the vertical moving component moves upward, so that the protective film is further separated from the product itself.
[0033] The air vent helps to blow the protective film up when it enters the film-tearing mechanism.
[0034] The feeding mechanism 2 is equipped with a fixing member 18 for fixing the product to be peeled off, and the part of the product without protective film is fixed by the fixing member 18.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
