Detailed Implementation

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] It should be noted that when a component is referred to as being "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0021] It should be understood that the terms "length", "width", "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] It's important to know that during the production, transportation, and storage of industrial products, a protective film is typically applied to the product surface to prevent damage from external environmental factors (such as dust adhesion, foreign object collisions, tool scratches, etc.) and to ensure the product's appearance integrity and performance stability upon leaving the factory. This protective film, as a temporary protective structure, effectively isolates external interference, providing protection throughout the product's transit lifecycle. However, after completing specific production processes (such as precision surface machining, assembly, quality inspection, or when the product is about to enter the packaging and shipping stage), the protective film must be removed to ensure the smooth progress of subsequent production processes or to meet the product's usage and delivery requirements.

[0024] Currently, the removal of protective films in industrial production is mainly addressed through several methods. One approach involves adding ear-shaped structures (extended protrusions for easy gripping) to the edges of the protective film, using a mechanical mechanism for rapid tearing. However, this design occupies additional film area, significantly reducing the actual utilization rate of the protective film. Furthermore, the processing and molding of the ear-shaped structure increases the production cost of the protective film. Another approach uses high-viscosity easy-tear adhesive tape applied to the surface of the protective film, with a mechanical device gripping the tape to complete the tearing action. However, easy-tear tape is a disposable consumable, and long-term use significantly increases consumable costs in the production process. Moreover, when the protective film itself has high adhesiveness, separating the easy-tear tape from the protective film becomes more difficult, leading to tearing failures and protective film residue, directly impacting production efficiency.

[0025] Based on this, this application improves the related film-tearing device and film-tearing equipment.

[0026] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of the film-tearing device provided in this embodiment is shown. Figure 2This embodiment provides the following: Figure 1 A partial enlarged schematic diagram of structure A. The film-tearing device of this application embodiment is used to remove the protective film from a product. The film-tearing device includes a film-lifting member 500 and a pressing member 400. The film-lifting member 500 is inserted between the product and the protective film. The film-lifting member 500 has a first side and a second side. When the film-lifting member 500 is inserted between the product and the protective film, the first side is the side of the film-lifting member 500 closer to the product, and the second side is the side closer to the protective film. The pressing member 400 is disposed on the second side of the film-lifting member 500, and the pressing member 400 has a first position away from the film-lifting member 500 and a second position closer to the film-lifting member 500. In the first position, an accommodating space is formed between the pressing member 400 and the film-lifting member 500, the accommodating space for the protective film to enter. The film-tearing device is configured to adjust the pressing member 400 to the second position to clamp the protective film when the protective film enters the accommodating space.

[0027] It should be explained that the film-peeling device is used to automatically remove the protective film from the surface of products. Through the coordinated functions of film lifting, clamping, and traction, it replaces manual or traditional semi-automatic methods to complete the film-peeling action, thereby improving the efficiency of film peeling. The film lifting component 500 is a part of the film-peeling device used to change the adhesion state between the protective film and the product. It can have a thin blade or wedge-shaped structure, which can be inserted into the gap between the product and the protective film. It breaks the adhesion between the two through physical action, providing an initial opening for subsequent clamping and peeling of the protective film. The appropriate structural hardness needs to be selected according to the material (soft / hard) and adhesiveness of the protective film.

[0028] The clamping component 400 is a functional part of the film-tearing device used to fix the protective film. Its position can be adjusted to open and close with the film-lifting component 500. When the protective film needs to be fixed, it moves closer to the film-lifting component 500 and clamps the protective film; when the protective film needs to be accommodated, it moves away from the film-lifting component 500 to create space. Its clamping force can be adjusted according to the characteristics of the protective film. The protective film is a protective material covering the surface of the product, usually made of materials such as plastic or film, used to prevent dust, scratches, or corrosion during product production, transportation, and storage. It is a temporary protective component and needs to be removed before subsequent processing or assembly. The accommodating space is the gap formed between the clamping component 400 and the film-lifting component 500 when the clamping component 400 is in the first position, used to accommodate the protective film, allowing the protective film lifted by the film-lifting component 500 to enter smoothly.

[0029] Understandably, this application eliminates the need for adding "ears" to the protective film or using consumables such as easy-tear stickers. It can directly adapt to conventional protective films, while avoiding increased costs due to consumable consumption or film removal failures, thus helping to reduce overall production costs. Specifically, the film lifting component 500 physically inserts to pick up the film, and the clamping component 400 mechanically clamps it in place. This eliminates the need for special processing of the protective film (such as adding "ears") and the consumption of consumables such as easy-tear stickers, directly reducing the cost of protective film procurement and consumables. At the same time, the clamping component 400's clamping and fixing improves the success rate of film removal, reduces product rework or protective film waste due to film removal failures, and further reduces production losses.

[0030] Please refer to the figures in some embodiments of this application. Figure 3 , Figure 3 A schematic diagram of the film-tearing device provided in this embodiment is shown; as follows: Figure 3 As shown, in this embodiment, the rotation direction of the second fixing member 200 is taken as the first direction a. The film-tearing device of this embodiment includes a first fixing member 100 and a second fixing member 200. The second fixing member 200 is disposed on the first fixing member 100, the film-lifting member 500 is disposed on the first fixing member 100, and the pressing member 400 is disposed on the second fixing member 200. The second fixing member 200 is configured to rotate relative to the first fixing member 100 to drive the pressing member 400 to the first position and the second position.

[0031] It should be explained that the first fixing member 100 is the component in the film-tearing device that bears the basic load-bearing function. It is usually made of rigid material and provides a stable installation reference. It is used to fix the film-lifting member 500 and support the second fixing member 200. At the same time, it can be connected to an external moving module to drive the entire film-tearing device to move in position. The second fixing member 200 is a movable component in the film-tearing device used to install the clamping member 400. It cooperates with the first fixing member 100 to realize the rotation function. By rotating itself, it can drive the clamping member 400 to move closer to or away from the film-lifting member 500, thereby switching the first position and the second position of the clamping member 400.

[0032] It is understood that the first fixing member 100 in this application fixes the film-lifting member 500 and the second fixing member 200 drives the clamping member 400 to rotate, which can ensure the precise coordination of the actions of the film-lifting member 500 and the clamping member 400. Since the position of the film-lifting member 500 is fixed, it is easy to stably insert the film between the product and the protective film. The second fixing member 200 drives the clamping member 400 to accurately approach or move away from the film-lifting member 500 by rotating, avoiding the protective film from failing to enter the receiving space or the clamping failure due to the positional deviation between the two, which is conducive to improving the connection efficiency of the film lifting and clamping actions. Specifically, in this application, the film-lifting component 500 is fixed on the first fixing component 100, and its position remains stable. When the second fixing component 200 rotates around the first fixing component 100, the movement trajectory of the pressing component 400 can precisely match the position of the second side of the film-lifting component 500. After the film-lifting component 500 lifts up the protective film, the rotation of the second fixing component 200 drives the pressing component 400 to quickly approach, precisely clamping the protective film between the film-lifting component 500 and the pressing component 400, without the need to repeatedly adjust the positions of the two.

[0033] In some embodiments, the film-forming member 500 is disposed at the end of the first fixing member 100.

[0034] In some embodiments, the clamping member 400 is disposed at the end of the second fixing member 200 near the film-forming member 500.

[0035] In some embodiments of this application, please refer to Figure 4 , Figure 4 A schematic diagram of the film-tearing device provided in this embodiment is shown. The first fixing member 100 of this embodiment has a recessed portion 110, within which a rotating shaft 111 is disposed. The two ends of the rotating shaft 111 are inserted into two opposite sidewalls within the recessed portion 110. The second fixing member 200 has a protruding portion 210, which is inserted into the recessed portion 110 and fixed to the rotating shaft 111.

[0036] It should be explained that the recess 110 is a groove-like structure provided on the first fixing member 100, which has space to accommodate the protrusion 210 of the second fixing member 200 and the rotating shaft 111. By limiting the range of motion of the protrusion 210, it ensures that the second fixing member 200 does not deviate when rotating, while providing a stable mounting carrier for the rotating shaft 111. The rotating shaft 111 is a cylindrical transmission component 800 used to connect the first fixing member 100 and the second fixing member 200. It is usually made of high-strength metal material, and its two ends are fixed to the opposite sidewalls of the recess 110 to ensure axial stability. It can limit the rotation of the second fixing member 200 to a preset axial direction. The protrusion 210 is a protruding structure provided on the second fixing member 200. It can be inserted into the recess 110 of the first fixing member 100 and fixed with the rotating shaft 111. The second fixing member 200 can rotate relative to the first fixing member 100 through the support of the rotating shaft 111. Its structural dimensions need to be adapted to the recess 110 to ensure that there is no excessive gap or interference during rotation.

[0037] It is understood that the recessed portion 110 of this application defines the installation position of the rotating shaft 111, and the protrusion 210 is fixed to the rotating shaft 111. This can strictly limit the rotation of the second fixing member 200 to the axial direction of the rotating shaft 111, avoid the offset caused by the instability of the fulcrum in the traditional rotating structure, ensure that the clamping member 400 is accurately switched to the first position and the second position, and help improve the coordination accuracy of the film-forming member 500 and the clamping member 400.

[0038] In some embodiments, the recess 110 is a through-hole structure.

[0039] Please refer to the embodiments described in this application. Figure 2 The film-tearing device in this embodiment also includes a third fixing member 300. The second fixing member 200 is disposed on the third fixing member 300, and a cylinder 310 is disposed on the third fixing member 300. The output end of the cylinder 310 is connected to the end of the second fixing member 200 away from the pressing member 400. The output end of the cylinder 310 is used to drive the second fixing member 200 to rotate relative to the first fixing member 100.

[0040] It should be explained that the third fixing member 300 is a structural component in the film-tearing device used to support the cylinder 310 and connect to the second fixing member 200. It typically possesses rigid support characteristics, providing a stable mounting reference for the cylinder 310 and also providing auxiliary positioning for the rotation of the second fixing member 200, preventing structural deformation caused by the direct application of the driving force of the cylinder 310 to the second fixing member 200. The cylinder 310 is an actuator that provides power for the rotation of the second fixing member 200. It converts the pressure of compressed gas into mechanical thrust or tension, and its output end is connected to the second fixing member 200, driving the second fixing member 200 to rotate precisely around the rotation axis 111, thereby controlling the switching position of the clamping member 400.

[0041] Understandably, the third fixing member 300 provides a fixed mounting reference for the cylinder 310, ensuring that the output end of the cylinder 310 is always aligned with the end of the second fixing member 200 away from the clamping member 400. The driving force can be transmitted in a preset direction, causing the second fixing member 200 to rotate smoothly around the rotation shaft 111. For example, when the cylinder 310 extends, it can drive the second fixing member 200 to rotate precisely from the first position away from the film-forming member 500 of the clamping member 400 to the second position where the clamping member 400 clamps the protective film.

[0042] Please refer to the embodiments described in this application. Figure 2 In this embodiment, a connector 320 is provided on the output end of the cylinder 310, and the connector 320 is rotatably connected to the end of the second fixing member 200 away from the clamping member 400.

[0043] Understandably, the rotational connection between the connector 320 and the second fixing member 200 coordinates the linear motion of the output end of the cylinder 310 with the rotational motion of the second fixing member 200, avoiding power transmission interruptions caused by differences in their motion trajectories. This ensures that the driving force of the cylinder 310 can be smoothly applied to the second fixing member 200, driving the clamping member 400 to precisely switch between the first and second positions. When the output end of the cylinder 310 extends or retracts in a linear motion, the connector 320 can synchronously adjust its angle with the rotation of the second fixing member 200, eliminating interference caused by differences in motion trajectories. For example, when the cylinder 310 drives the second fixing member 200 to rotate around the rotation axis 111, the connector 320, through its relative rotation with the second fixing member 200, adapts to the linear displacement of the piston rod of the cylinder 310 and the arcuate displacement of the force point of the second fixing member 200, ensuring lossless transmission of driving force and preventing the clamping member 400 from failing to clamp the protective film in time due to jamming, thus ensuring continuous and smooth film-tearing action.

[0044] Please refer to the embodiments described in this application. Figure 2 In this embodiment, the clamping member 400 is a roller, and the rotation direction of the roller is the same as the direction in which the protective film enters the accommodating space.

[0045] It should be explained that a roller is a cylindrical component with a rolling function, usually made of materials such as metal, rubber, or plastic. It can rotate around its own axis and replace the sliding contact with the protective film through rolling contact. This can both press and fix the protective film and reduce frictional damage to the surface of the protective film.

[0046] Understandably, the rollers in this application interact with the protective film through rolling contact. Compared to the sliding contact of traditional grippers, this significantly reduces the frictional resistance between the clamping element 400 and the protective film. Simultaneously, the unidirectional rotation provides auxiliary conveying power for the protective film, preventing breakage or product displacement due to excessive resistance, thus reducing the risk of malfunctions during the film-tearing process. The rolling contact between the rollers and the protective film in this application converts sliding friction into rolling friction, significantly reducing frictional resistance. Furthermore, the unidirectional rotation provides a slight pushing force for the protective film to enter the receiving space, allowing it to enter the clamping area more smoothly. This eliminates the need for strong pulling force during the film-tearing device's movement to detach the protective film from the product, preventing product displacement or film breakage due to excessive pulling force.

[0047] The rollers rotate in the same direction as the protective film enters, guiding the film along a preset path while clamping it. This avoids the problem of the protective film gathering at the cutting edge of the film-lifting component 500 when tearing film with a traditional scraper, ensuring the film remains flat and facilitating subsequent tearing. In this application, after the protective film lifted by the film-lifting component 500 enters the receiving space, the rollers rotate in the same direction, actively conveying the protective film away from the cutting edge of the film-lifting component 500. This ensures the film continuously adheres to the roller surface and extends without wrinkles or accumulation. For example, when the protective film detaches from the product surface and moves into the receiving space, the synchronous rotation of the rollers guides the film's movement.

[0048] In some embodiments, the rollers may be made of metal or metallic materials.

[0049] In some embodiments, the rollers may be multi-layered or single-layered structures.

[0050] In some embodiments, a brush may be provided on the roller to form a roller brush structure.

[0051] Please refer to the embodiments described in this application. Figure 2 In this embodiment, the film-forming component 500 is a spatula.

[0052] Please refer to the embodiments described in this application. Figure 2 The film-tearing device in this embodiment also includes a motor 700 and a transmission component 800. The motor 700 is mounted on the second fixing member 200. The motor 700 is connected to the transmission component 800 in a transmission connection, and the transmission component 800 is connected to the roller in a transmission connection.

[0053] It should be explained that the motor 700 is the drive component that provides power for the rotation of the roller, and it can have the characteristics of adjustable speed and stable output torque. The transmission component 800 is the power transmission assembly that connects the motor 700 and the roller, and can smoothly transmit the power output by the motor 700 to the roller, so that the roller can rotate in a preset direction and speed. Common forms include belts, gears, and drive pulleys.

[0054] Understandably, this application ensures a precise match between the roller rotation speed and the speed at which the protective film enters the receiving space via the transmission component 800, and even provides rotational power slightly greater than the film's entry speed. This actively transports the protective film away from the cutting edge of the film-lifting component 500, solving the problem of protective film accumulation at the cutting edge when using a traditional scraper to tear the film. The motor 700 in this application drives the roller to rotate in the same direction via the transmission component 800, actively pulling the protective film so that it is immediately stretched by the roller upon entering the receiving space, preventing it from accumulating at the cutting edge of the film-lifting component 500. For example, at the instant the film-lifting component 500 lifts the protective film into the receiving space, the roller is already rotating synchronously under the drive of the motor 700, quickly guiding the protective film to its own surface and preventing wrinkles or accumulation.

[0055] Please refer to the embodiments described in this application. Figure 2 In this embodiment, the transmission component 800 is a belt. One side of the belt is connected to the output end of the motor 700, and the other side of the belt is connected to the shaft of the roller to drive the roller to rotate.

[0056] Understandably, the flexibility of the belt can buffer the instantaneous impact force when the motor outputs 700, avoiding power fluctuations caused by rigid transmission (such as gear transmission). At the same time, the friction between the belt and the wheel body enables smooth power transmission, ensuring that the roller can rotate at a preset speed. This helps to prevent wrinkles or aggregation of the protective film caused by sudden changes in the roller speed.

[0057] In some embodiments, the transmission component 800 may be a gear or a gear set.

[0058] Please refer to the embodiments described in this application. Figure 1 The film-tearing device in this embodiment includes a fixed base 600. The third fixing member 300 is connected to the fixed base 600 through a telescopic rod. A spring is sleeved on the telescopic rod. One end of the spring abuts against the third fixing member 300, and the other end of the spring abuts against the fixed base 600.

[0059] In some embodiments, there are two telescopic rods, which are arranged side by side between the third fixing member 300 and the fixing base 600.

[0060] Furthermore, to better implement the film-tearing device in any of the above embodiments, based on the above film-tearing device, this application embodiment also provides a film-tearing device, including the film-tearing device as described above.
