[0001] This utility model relates to the field of product surface cleaning technology, and in particular to a film-removing device. Background Technology

[0002] In the manufacturing process of electronic products, especially in the production of precision components such as cameras, it is necessary to peel off the protective film from components such as lenses and circuit boards. Existing technology involves a continuously running adhesive tape moving sequentially to different positions at a peeling station, where the tape adheres to the protective film on the product, thus achieving peeling. However, in practical applications, relying solely on the adhesive force of the tape for peeling is unreliable, and peeling failures are common. Improving the success rate of film peeling is a pressing technical problem that needs to be solved in this field. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] See Figure 1 and Figure 2 As shown, this utility model discloses an embodiment of the film-tearing device.

[0020] The aforementioned film-tearing equipment includes a frame 1 and a film-tearing assembly. The film-tearing assembly is mounted on the frame 1 and includes an unwinding mechanism 21, a winding mechanism 22, a guide roller mechanism 23, a top support mechanism 24, and a peeling mechanism 25. The unwinding mechanism 21 is used to unwind the tape 3, the winding mechanism 22 is used to wind the tape 3, the guide roller mechanism 23 is used to guide the tape 3 between the unwinding mechanism 21 and the winding mechanism 22 through the film-tearing station, and the top support mechanism 24 includes a top support member 241, a first connecting member 242, and a first driving member 243. 1. The first driving member 243 is connected to the first connecting member 242. The first driving member 243 drives the top support member 241 to move up and down below the film-tearing station. The peeling mechanism 25 includes a peeling rod 251, a second connecting member 252 and a second driving member 253. The peeling rod 251 extends horizontally and is connected to the second driving member 253 through the second connecting member 252. The second driving member 253 drives the peeling rod 251 to move horizontally above the film-tearing station. The direction of the horizontal movement of the peeling rod 251 is perpendicular to its length direction.

[0021] In the above text, frame 1 refers to the basic framework that supports all functional modules, providing rigid support for the equipment. Unwinding mechanism 21 is a device that stores and releases the tape roll, controlling the unwinding speed to match the film-tearing rhythm. Rewinding mechanism 22 is a device that recycles used tape, maintaining the stability of the tape's travel path. Guide roller mechanism 23 is a device that guides the tape's movement direction, ensuring the tape maintains a predetermined trajectory when passing the film-tearing station. Top support 241 is a component that contacts and lifts the tape, forming a contact surface with the tape during lifting. First drive component 243 is a power element that generates linear motion, controlling the vertical displacement of the top support 241. Peeling rod 251 is a slender component that peels off the protective film, generating peeling force through translational motion. Second drive component 253 is a power element that generates horizontal movement, driving the peeling rod 251 to move in a predetermined direction.

[0022] Specifically, after the tape 3 is released from the unwinding mechanism 21, it is guided by the guide roller mechanism 23 to form a path through the film-tearing station. A robotic arm stops the product to be peeled above the film-tearing station, and the first drive member 243 of the support mechanism 24 pushes the support member 241 upward, causing the tape 3 to contact the product surface. Then, the first drive member 243 of the support mechanism 24 pushes the support member 241 downward, creating an opening between one end of the protective film and the product. Subsequently, the peeling rod 251 moves horizontally under the drive of the second drive member 253. As the peeling rod 251 continues to move horizontally, the protective film is continuously peeled off and adhered to the tape 3, and finally, it is retrieved by the winding mechanism 22 and removed from the work area. Throughout the horizontal movement, the peeling rod 251 maintains contact with the protective film through its arc-shaped surface.

[0023] The above technical solution utilizes the coordinated action of the unwinding mechanism, winding mechanism, guide roller mechanism, top support mechanism, and peeling mechanism to directly adhere the protective film to the tape, and then peels off the protective film using a peeling rod. This method is simple, efficient, and has a high success rate in peeling the film.

[0024] In this embodiment, the translational direction of the peeling rod 251 is consistent with the travel direction of the tape 3.

[0025] In the above text, the translational direction of the peeling rod 251 refers to the direction of its movement trajectory on the horizontal plane. The travel direction of the conveyor belt 3 refers to the continuous conveying path of the conveyor belt 3 from the unwinding mechanism 21 through the guide roller mechanism 23 to the winding mechanism 22.

[0026] Specifically, during the film peeling process, the tape 3 remains stationary. When the peeling rod 251 moves horizontally along the tape's travel direction, the protective film is subjected to the peeling force of the peeling rod 251, and the tape 3 is also subjected to a force in the same direction. When this force is consistent with the tape's travel direction, it can prevent the tape from shifting laterally after being subjected to force.

[0027] With the above technical solution, the translational direction of the peeling rod is consistent with the travel direction of the conveyor belt, which can ensure that the peeling action is synchronized with the conveyor belt conveying rhythm and ensure the smooth progress of the peeling action.

[0028] In this embodiment, the peeling rod 251 is a knurled steel rod that has undergone anti-sticking treatment.

[0029] In the above text, knurled steel bar refers to a metal bar with regular patterns formed by mechanical rolling on its surface. Anti-stick treatment refers to a process that reduces the adhesion of metal surfaces, forming a non-stick protective layer on the metal surface.

[0030] Specifically, when the tape 3 is lifted by the supporting mechanism 24 at the film-tearing station, its adhesive surface easily comes into contact with the surface of the peeling rod 251. The uneven structure formed by the knurling makes it difficult for the tape to stick to the peeling rod.

[0031] The above technical solution can prevent the glass rod from sticking to the tape, which could lead to peeling failure.

[0032] In this embodiment, the second driving component 253 is a cylinder.

[0033] As described above, a cylinder is a pneumatic actuator that converts the pressure energy of compressed air into mechanical kinetic energy to achieve linear reciprocating motion or oscillation. The cylinder achieves motion through the intake-exhaust cycle.

[0034] Specifically, the required motion precision of the stripping rod 251 is not high; it only needs to achieve translation, and the requirements for its position and speed before and after translation are not high. Therefore, it can be driven by a cylinder.

[0035] The above technical solution results in a cylinder with a simple structure, low cost, and fast response, which helps to reduce equipment costs.

[0036] In this embodiment, the top support 241 includes a support 2411 and a silicone strip 2412. The support 2411 is connected to the first connector 242, and the silicone strip 2412 is embedded in the top of the support 2411.

[0037] In the above text, support 2411 refers to a rigid support component used to transmit lifting power. It is fixedly connected to the first connecting member to ensure the stability of the top support action. Silicone strip 2412 refers to an elastic contact component that buffers contact pressure through material properties, preventing hard materials from directly contacting the product surface.

[0038] Specifically, during the lifting and lowering process, the support 2411 is rigidly connected to the first drive 243 through the first connector 242 to ensure the accurate transmission of the lifting action; the silicone strip 2412 is embedded in the top of the support 2411. When the support rises to the film-tearing station, the silicone strip 2412 contacts the tape 3 and lifts the tape 3 to contact the protective film on the product, preventing rigid impact from causing scratches on the product surface.

[0039] Through the above technical solution, the rigid structure of the support maintains the stability of the supporting action, while the flexible contact of the silicone strip eliminates the risk of damage to traditional rigid supporting components. The combination of the two achieves a balance between supporting function and surface protection.

[0040] In this embodiment, the two guide roller mechanisms 23 are located on both sides of the film-tearing station and are at the same height.

[0041] In the above text, the guide roller mechanism 23 refers to the guiding device used to guide the travel path of the conveyor belt, which achieves the guiding function through the contact friction between the roller surface and the conveyor belt. "Height consistency" means that the central axes of the roller bodies of the two guide roller mechanisms 23 are on the same horizontal plane, ensuring that the conveyor belt remains horizontal when entering and leaving the film-tearing station.

[0042] Specifically, the tape 3, after passing through the film-peeling station, moves horizontally to match the translation path of the peeling rod 251. As the peeling rod 251 moves, the protective film is gradually peeled off and smoothed onto the adhesive surface of the tape.

[0043] The above technical solution ensures that the position of the tape matches the translational trajectory of the peeling rod, thereby ensuring that the protective film is evenly adhered to the tape.

[0044] In this embodiment, the frame 1 includes a housing (not shown in the figure), a first support 11, a second support 12, and a guide rail mechanism. The housing has an inlet and outlet at one end along the horizontal direction, and a film-tearing opening at the top of the housing. The second support 12 is movably connected to the top of the first support 11 via the guide rail mechanism. The film-tearing assembly is mounted on the second support 12. In the first state, the unwinding mechanism 21 and the winding mechanism 22 are hidden inside the housing, and the film-tearing station exposes the film-tearing opening of the housing. In the second state, the unwinding mechanism 21 and the winding mechanism 22 enter and exit the housing from the inlet and outlet of the housing.

[0045] In the above text, the housing refers to the protective assembly surrounding the internal structure of the equipment, used to isolate the external environment from the internal mechanisms. The guide rail mechanism refers to the mechanical guiding device that enables linear motion, used to support the translational movement of the second support 12. The inlet and outlet refer to the rectangular channels opened on the side wall of the housing, used for the unwinding mechanism 21 and the rewinding mechanism 22 to enter and exit the housing. Among them, the tearing opening refers to the strip-shaped opening opened on the top of the housing, used to expose the tearing station and restrict the entry of contaminants.

[0046] Specifically, during equipment operation, the second support 12 forms a retractable connection structure with the first support 11 via a guide rail mechanism. When a film-tearing operation is required, the second support 12 is in the first working position, at which point the unwinding mechanism 21 and the winding mechanism 22 are completely housed within the casing, with only the peeling station exposed through the film-tearing opening, preventing the tape roll from being exposed to the workshop environment. When tape replacement or equipment maintenance is required, the second support 12 moves along the guide rail mechanism to the second working position, causing the unwinding mechanism 21 and the winding mechanism 22 to fully extend from the inlet / outlet on the side of the casing, allowing operators to directly access the relevant components.

[0047] The above technical solution enables the overall translation of the core components of the equipment by setting up a shell and making the frame retractable, thus avoiding the disassembly of the shell. At the same time, the physical isolation design between the shell inlet / outlet and the tear-off opening effectively reduces the risk of external dust entering the equipment during maintenance.

[0048] In this embodiment, the second bracket 12 has a first end and a second end along the translation direction. The first end of the second bracket 12 is close to the inlet and outlet of the housing. The unwinding mechanism 21 and the winding mechanism 22 are arranged vertically on the first end of the second bracket 12. The guide rail mechanism is connected to the second end of the second bracket 12.

[0049] Through the above technical solution, the second support 12 having a first end and a second end along the translational direction means dividing the support along the horizontal movement path into an end near the inlet and outlet of the housing and an end away from the inlet and outlet. The unwinding mechanism 21 and the winding mechanism 22 being arranged vertically means being stacked in the vertical direction to facilitate their entry and exit from the housing. The guide rail mechanism connecting the second end of the second support means that the sliding guide component is set at the end of the support away from the inlet and outlet.

[0050] Specifically, when the second support 12 is inside the housing, the stacked unwinding mechanism 21 and winding mechanism 22 are completely housed within the housing, and the film-tearing station is exposed to the external operating area through the opening at the top of the housing. When it is necessary to replace the tape or maintain the equipment, the second support 12 moves outward along the guide rail. Its first end, carrying the stacked unwinding mechanism 21 and winding mechanism 22, moves out of the housing inlet and outlet, while the second end maintains the stability of the translation trajectory through the guide rail mechanism. Since the unwinding mechanism 21 and winding mechanism 22 are concentrated at the first end near the inlet and outlet, the translational stroke required for their entry and exit is shortened. At the same time, the guide rail mechanism is located at the second end, allowing the first end of the second support 12 to extend out of the housing.

[0051] The above technical solution facilitates the entry and exit of the unwinding and rewinding mechanisms from the housing by using a longitudinally stacked roll material mechanism and defining the guide rail connection position.

[0052] In this embodiment, the guide rail mechanism includes a first slide rail 131, a first slider 132, a second slide rail 133, and a second slider 134. The first slide rail 131 is connected to the first bracket 11, the first slider 132 is slidably connected to the first slide rail 131, the second slide rail 133 is connected to the first slider 132, the second slider 134 is slidably connected to the second slide rail 133, and the second bracket 12 is connected to the second slider 134. The length directions of the first slide rail 131 and the second slide rail 133 are consistent.

[0053] In the above text, the first slide rail 131 refers to a linear guide component, whose function is to provide an axial sliding reference for the first slider 132. The first slider 132 refers to a moving component that cooperates with the first slide rail 131. The second slide rail 133 refers to a linear guide component, whose function is to provide a sliding degree of freedom for the second slider 134. The second slider 134 refers to a moving component that cooperates with the second slide rail 133.

[0054] Specifically, when the second support 12 is pulled, the second slider 134 moves along the second slide rail 133 and the first slider 132 moves along the first slide rail 131, thus achieving double the stroke.

[0055] Through the above technical solution, the guide rail mechanism achieves double the stroke for the same length, which can reduce the length of the equipment.

[0056] In this embodiment, the first bracket 11 is supported at the bottom of the guide rail mechanism, the second bracket 12 is installed above the guide rail mechanism, and the film-tearing assembly is installed on the side of the second bracket 12.

[0057] In the preceding text, the bottom support of the first bracket 11 ensures the structural rigidity of the guide rail mechanism during movement. The guide rail mechanism refers to the guiding component that enables the translational movement of the second bracket. The second bracket 12 refers to a movable frame for mounting the film-tearing assembly, and its upper mounting position facilitates spatial separation from the guide rail mechanism. The film-tearing assembly refers to an execution unit that includes unwinding, rewinding, and peeling functions, and can be implemented using a lateral cantilever mounting method. Its lateral arrangement avoids spatial interference with the upper and lower layers of the bracket.

[0058] Specifically, the first support 11 forms a stable base frame through the bottom support guide rail mechanism. The guide rail mechanism is divided into upper and lower motion tracks in the vertical direction. The second support 12 realizes translational movement through the upper track. The film tearing component is laterally fixed to the side of the second support.

[0059] The above technical solutions ensure the structural strength of each part while making the overall equipment structure compact.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
