Description

Technical Field

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

[0002] In the manufacturing and processing of electronic components, optical lenses, displays, and other products, it is often necessary to peel off the protective film attached to the surface of the substrate to meet the requirements of subsequent processes for product surface cleanliness and precision. Traditional film peeling equipment usually adopts an adhesive peeling structure, the core component of which is a peeling head equipped with adhesive material (such as adhesive tape, silicone block, etc.). The peeling head contacts the surface of the protective film, and the adhesive material separates the protective film from the substrate.

[0003] However, during use, the adhesive strength of the bonding material in the aforementioned adhesive-based film-tearing structure is easily weakened due to dust, impurities, or material fatigue, leading to decreased film-tearing reliability and even film-tearing failure. To maintain the film-tearing effect, frequent shutdowns are required to replace the adhesive material on the film-tearing head or the entire film-tearing structure. This not only increases equipment downtime and reduces production efficiency but also increases consumable costs due to the continuous consumption of adhesive material. To solve the above problems, this application proposes a film-tearing device. Utility Model Content

[0004] The purpose of this invention is to provide a film-tearing device to solve the problem that current film-tearing devices require frequent maintenance.

The two conveyor components located on the first support plate and the second support plate rotate synchronously and are belt conveyor structures.

[0009] Furthermore, the workpiece transfer mechanism also includes: A lifting assembly is used to lift the workpiece. The suction cup structure of the fixing assembly is fixedly connected to the output end of the lifting assembly and rises and falls synchronously with the lifting assembly.

[0010] Furthermore, the workpiece transfer mechanism also includes: A lead screw, one end of which is rotatably connected to the second support plate, and the other end of which passes through the first support plate, and the lead screw and the first support plate are connected by threads; A guide rail is fixed relative to the second support plate, and the second support plate is perpendicular to the guide rail.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides a film-removing device, which includes a workpiece transfer mechanism 200, a film-removing component 300, and a displacement mechanism 400. The workpiece transfer mechanism 200 is located below the film-removing component 300 and the displacement mechanism 400. A fixing component 260 for fixing the workpiece is provided at a preset station of the workpiece transfer mechanism 200. The film-removing component 300 is a gripper structure and is used to grasp the protective film on the workpiece. The displacement mechanism 400 is used to drive the film-removing component 300 to move in space to realize the automatic removal of the protective film on the surface of the workpiece.

[0025] Specifically, in this embodiment, when peeling the protective film off the product, the workpiece flows through the workpiece transfer mechanism 200, is transported to a preset station by the workpiece transfer mechanism 200, and is fixed by the fixing component 260 to ensure the workpiece's position is stable. Subsequently, the displacement mechanism 400 is activated, controlling the film-peeling component 300 to move precisely above the protective film on the workpiece surface. The film-peeling component 300 clamps the edge of the protective film, and through the continuous movement of the displacement mechanism 400, smoothly peels the protective film off the workpiece surface at a constant speed. The peeled protective film automatically detaches, and the workpiece flows to the next process, completing the automated film-peeling process.

[0026] The film-tearing device disclosed in this embodiment of the invention precisely controls the spatial position of the film-tearing component 300 through the displacement mechanism 400 and performs a clamping action to firmly hold the edge of the protective film. The displacement mechanism 400 drives the film-tearing component 300 to move at a uniform speed along a preset trajectory, ensuring that the protective film is smoothly and continuously peeled off the workpiece surface, avoiding film breakage or residue due to sudden speed changes or uneven force. The entire film-tearing process requires no manual intervention, significantly improving work efficiency and consistency. Furthermore, due to the use of a clamping structure to fix the protective film, compared to the traditional adsorption-type film-tearing method, the maintenance frequency is effectively reduced.

[0027] Specifically, such as Figure 7 As shown, the workpiece transfer mechanism 200 includes a first support plate 210 and a second support plate 220. The first support plate 210 and the second support plate 220 are arranged in parallel and are located on opposite sides of the workpiece transfer direction. A synchronously rotating transfer component 240 is provided on the first support plate 210 and the second support plate 220 for transporting the workpiece to a preset station. The transfer component 240 is a belt conveyor structure, comprising a pulley rotatably connected to the first support plate 210 or the second support plate 220, a conveyor belt sleeved on the pulley, and a belt motor driving the pulley to rotate. The fixing component 260 is located between the first support plate 210 and the second support plate 220 and cooperates with the transfer component 240 to ensure that the workpiece remains stable and accurately positioned at the preset station during transfer. When the workpiece reaches the designated position, the fixing component 260 fixes the workpiece to prevent displacement during the film-tearing process, ensuring the accurate execution of the film-tearing action. In this embodiment, the fixing component 260 adopts a suction cup structure, which firmly fixes the workpiece in the preset position by negative pressure adsorption, avoiding positional displacement caused by external force. The suction cup is made of flexible silicone, which can ensure stable adsorption force and prevent damage to the workpiece surface.

[0028] It should be noted that, in this embodiment, the workpiece transfer mechanism 200 also includes accessories for traditional transfer structures, such as a stop structure and a positioning sensor set at a preset workstation. These accessories are used to achieve precise positioning and limiting when the workpiece arrives at the preset workstation, preventing positional deviation due to inertia. The stop structure is synchronously linked with the transfer component 240 to ensure that the workpiece is locked at the moment of stopping, improving the positioning repeatability. The positioning sensor is a photoelectric sensor in the prior art, used to detect in real time whether the workpiece has reached the preset position and to feed the signal back to the control structure on the production line. The control structure automatically adjusts the belt conveyor speed and start / stop timing based on the feedback signal to ensure that the workpiece stops accurately at the center of the preset workstation each time. When the positioning sensor detects that the workpiece has arrived, it immediately triggers the fixing component 260 to perform an adsorption action, and synchronously transmits a signal to the displacement mechanism 400 to start the positioning calibration program. After confirming that the initial position of the film-tearing component 300 is without deviation, it enters the film-tearing preparation state.

[0029] The fixing component 260 is a suction cup structure in the prior art. It is connected to the control structure through a negative pressure generator to achieve a stable working mode with fast start and stop response and adjustable adsorption force. It can dynamically adjust the vacuum degree according to the surface characteristics of different workpieces to ensure reliable fixing on smooth or slightly rough surfaces.

[0030] Preferably, the workpiece transfer mechanism 200 further includes a lifting component 250 for lifting the workpiece, facilitating its smooth lifting from the transfer component 240 after it has moved to a preset station, thus avoiding frictional resistance with the conveyor surface during film removal. The lifting component 250 works in conjunction with the fixing component 260, rising synchronously after the workpiece is positioned, detaching the workpiece from the belt surface and maintaining a stable, suspended state, thereby improving film removal accuracy and operational smoothness. The lifting action is pneumatically driven, with rapid response and controllable stroke, ensuring precise adaptation to workpieces of different thicknesses. The lifting component 250 uses a cylinder structure, as is common in the prior art. The suction cup structure of the fixing component 260 is fixedly connected to the output end of the lifting component 250, rising and falling synchronously with it, ensuring the workpiece remains horizontal during lifting.

[0031] Preferably, the output end of the lifting assembly 250 is also fixed with a positioning pin 290. The positioning pin 290 is in the same direction as the lifting and is used to provide positioning function after the workpiece is lifted. The positioning pin 290 cooperates with the structure (positioning hole or positioning groove) on the workpiece to position the workpiece.

[0032] In a preferred embodiment of this invention, the distance between the first support plate 210 and the workpiece transfer mechanism 200 is adjustable to accommodate workpieces of different sizes and specifications. By adjusting the distance between the first support plate 210 and the workpiece transfer mechanism 200, the continuous production needs of various product models can be flexibly met, improving the versatility of the production line.

[0033] Specifically, the workpiece transfer mechanism 200 further includes a lead screw 230, a guide rail 270, and a slider 280. One end of the lead screw 230 is rotatably connected to the second support plate 220, and the other end of the lead screw 230 passes through the first support plate 210. The lead screw 230 and the first support plate 210 are connected by a thread. By rotating the lead screw 230, the first support plate 210 can be moved axially, thereby adjusting the relative distance between the first support plate 210 and the workpiece transfer mechanism 200. The guide rail 270 is fixed relative to the second support plate 220, and the second support plate 220 is perpendicular to the guide rail 270. If both are fixed to the base 100, the overall structure is stable and reliable. The slider 280 is fixed to the first support plate 210 and moves synchronously with it. The slider 280 is slidably connected to the guide rail 270, and the slider 280 can slide axially along the guide rail 270 to guide and support the first support plate 210 during movement, ensuring a smooth and stable adjustment process. The guide rail 270 is an I-shaped guide rail, and the slider 280 is provided with a matching groove structure, so that the two have high guiding accuracy and load-bearing capacity when sliding together.

[0034] Preferably, multiple guide rails 270 and sliders 280 are provided, and the multiple guide rails 270 and sliders 280 are arranged in an array on the first support plate 210.

[0035] The lead screw 230 and the second support plate 220 are rotatably connected by bearings to ensure smooth rotation and uniform axial force. The lead screw 230 and the first support plate 210 are threadedly connected by a threaded bushing structure to facilitate precise control of the displacement stroke of the first support plate 210.

[0036] Preferably, a handwheel 231 is provided at the end of the lead screw 230, which allows the user to rotate the lead screw 230 and achieve precise adjustment by manual or tool force application.

[0037] Preferably, there are two lead screws 230. Each lead screw 230 is provided with a synchronous pulley 232 at the end away from the second support plate 220. The synchronous pulleys 232 are connected by a synchronous belt to realize the synchronous rotation of the two lead screws 230, ensuring that the adjustment accuracy on both sides is consistent and avoiding the phenomenon of uneven load or jamming caused by unilateral adjustment.

[0038] The film-tearing component 300 is a pneumatic gripper structure in the prior art, which uses air pressure to drive the opening and closing of the gripping end for gripping the protective film.

[0039] Preferred, such as Figures 2 to 5 As shown, two film-tearing components 300 are provided. One film-tearing component 300 is vertically arranged, and the other is inclined, forming a V-shape. The clamping ends of both components face the apex of the V-shape. In this embodiment, the V-shaped clamping layout of the film-tearing components 300 ensures that if one component fails to grip the film properly, the second component can perform a secondary gripping action based on the first component, preventing such failures. The clamping actions of the two film-tearing components 300 are controlled by independent air circuits, enabling time-division opening and closing to ensure orderly gripping.

[0040] like Figure 3 , Figure 4 and Figure 6 As shown, the displacement mechanism 400 includes a first horizontal moving member 410, a second horizontal moving member 420, and a vertical moving member 430. The first horizontal moving member 410 is fixed to the workpiece transfer mechanism 200 and is used to control the entire displacement mechanism 400 to move along a first direction on a horizontal plane. The second horizontal moving member 420 is fixed to the first horizontal moving member 410 and can move relative to it in a second direction to achieve precise positioning in a two-dimensional plane. The first direction and the second direction are perpendicular to each other and form a rectangular coordinate system. The vertical moving member 430 is fixed to the second horizontal moving member 420 and is used to support the film-tearing member 300 and realize the lifting and lowering movement in a third direction, so that the film-tearing member 300 can be precisely positioned and moved in three-dimensional space to meet the film-tearing operation.

[0041] In this embodiment, the first horizontal moving component 410, the second horizontal moving component 420, and the vertical moving component 430 are all prior art. For example, the first horizontal moving component 410 is a belt linear displacement module in the prior art. The first horizontal moving component 410 includes two belt conveyors 411. The two belt conveyors 411 are arranged in parallel to ensure that the overall structure remains stable and synchronous when moving in the first direction, avoiding shaking or deviation caused by uneven force. At the same time, the two belt conveyors 411 are driven by the same belt motor 412 to ensure synchronous operation, improve movement accuracy and stability. The power ends of the two belt conveyors 411 are connected by a synchronizing rod 413 to achieve balanced power transmission, ensuring that the first horizontal moving component 410 has no deviation or lag during operation.

[0042] The second horizontal moving part 420 adopts a screw drive structure or a belt linear displacement structure with the first horizontal moving part 410. The second horizontal moving part 420 is located at the output end of the first horizontal moving part 410, and the vertical moving part 430 is located at the output end of the second horizontal moving part 420. The first horizontal moving part 410, the second horizontal moving part 420 and the vertical moving part 430 form a gantry structure layout to achieve precise removal of the protective film.
