Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, and specifically to a film applicator. Background Technology

[0002] In the manufacturing and processing of electronic products, switching components, and other products, functional films (such as protective films, explosion-proof films, and optical films) are typically applied to the product surface to achieve requirements such as surface protection, scratch resistance, and surface smoothing. Currently, the equipment used in the industry for film application generally suffers from complex structures and cumbersome operating procedures.

[0003] Most existing film application equipment adopts a step-by-step operation mode of "cutting first, then applying": first, a separate die-cutting device cuts the roll of film into a shape that fits the product, and then the cut film is transferred to the product surface manually or by another application device to complete the application. This mode not only requires multiple machines to work together, resulting in large equipment footprints and high investment costs, but also, due to the intermediate film transfer step, the film is prone to dust contamination and positioning deviations, thus affecting the application quality. At the same time, the step-by-step operation also prolongs the production cycle, making it difficult to meet the needs of efficient mass production.

[0004] Therefore, there is an urgent need for a film-applying device that is simple in structure, highly integrated, and capable of simultaneously cutting and stably attaching films, while also balancing cost and efficiency, in order to solve the problems of complex equipment, insufficient precision, and low efficiency in existing technologies.

[0012] The beneficial effects of this utility model are: 1. Achieve simultaneous cutting and application, improving work efficiency: This film applicator uses a die-cutting drive to engage the pressure bar with the die-cutting block's cutting edge. While the pressure bar cuts the roll of film into the cutting edge shape, the cut film is directly applied to the surface of the product below, eliminating the traditional step-by-step process of "cutting first, then transferring and applying," avoiding time-consuming intermediate steps, significantly shortening the production cycle, and meeting the needs of mass production.

[0013] 2. Simplified structural design, reduced cost and maintenance difficulty: The equipment achieves cutting and pressing actions through only one set of die-cutting drive components, eliminating the need for multiple independent drive components and reducing structural redundancy; at the same time, it integrates film roll unwinding, die-cutting, product conveying, and waste material rewinding functions into one unit, simplifying the overall layout and reducing equipment manufacturing costs and subsequent maintenance complexity.

[0014] 3.

[0022] 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.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This utility model provides a film applicator.

[0025] In this embodiment, refer to Figure 1-4 The film applicator includes a worktable 1, a die-cutting assembly 2, a product conveying rail 3, a film roll unwinding mechanism 4, and a waste material winding mechanism 5. The die-cutting assembly includes a support 6, a die-cutting block 7, a guide block 34, a die-cutting drive 8, and a pressure rod 9. The guide block 34 is located above the die-cutting block and is connected to the support. There is a through groove 10 between the guide block and the die-cutting block for the film to pass through. A cutting edge 11 is provided on the die-cutting block located below the through groove 10. A pressure rod hole 12 is provided on the die-cutting block facing the cutting edge. The die-cutting drive is fixed on the support. The pressure rod is telescopically engaged with the pressure rod hole and connected to the output end of the die-cutting drive. The shape of the pressure rod is adapted to the pressure rod hole. The film roll unwinding mechanism and the waste material rewinding mechanism are respectively located on both sides of the die-cutting assembly, and the product conveying rail is set on the worktable and passes under the die-cutting block.

[0026] In the above technical solution, an installation carrier is set on the workbench, integrating a die-cutting assembly, a product conveying rail, a film roll unwinding mechanism, and a waste material rewinding mechanism. The die-cutting assembly is fixed by a bracket, with guide blocks corresponding vertically to the die-cutting block, and a through groove between them providing a conveying channel for the film roll. The cutting edge on the die-cutting block engages with an opposite pressure rod hole, and the pressure rod can extend and retract along the pressure rod hole under the drive of the die-cutting drive. The film roll unwinding mechanism and the waste material rewinding mechanism are located on opposite sides of the die-cutting assembly, forming a conveying path for the film roll of "unwinding-processing-waste recycling," with the product conveying rail passing under the die-cutting block. During operation, the film roll enters the through groove through the unwinding mechanism, and the die-cutting drive drives the pressure rod downwards. The pressure rod, in conjunction with the cutting edge, cuts the film roll into the cutting edge shape. Simultaneously, the pressure rod directly presses the cut film onto the product surface on the product conveying rail below, while the waste material is recycled by the rewinding mechanism. It enables simultaneous film cutting and application, significantly shortening the production cycle and improving batch operation efficiency. The shape of the pressure bar and pressure bar hole are matched, and the cutting edge and pressure bar are precisely aligned, ensuring the accuracy of cutting dimensions and film application position, and avoiding the positioning deviation caused by traditional transfer application.

[0027] Specifically, the bracket includes a front upright plate 13 and a rear upright plate 14, which are fixed at intervals on the workbench. Positioning grooves 15 are provided on the front and rear upright plates, and sliding steps 16 connected to the positioning grooves 15 are provided on the die-cutting block and the guide block.

[0028] In this embodiment, the support consists of a front plate and a rear plate fixed at intervals on the worktable, and positioning grooves are provided on the two plates; sliding steps are machined on the die-cutting block and the guide block, and the sliding steps can be embedded in the positioning grooves to realize the connection and positioning of the die-cutting block, the guide block and the support.

[0029] Specifically, the die-cutting block is provided with fitting grooves 17 on both sides, the guide block is provided with fitting protrusions 18 on both sides that are adapted to the fitting grooves 17, and the die-cutting block and the guide block are provided with fixing holes 19 at the four corners for fixing the die-cutting block and the guide block.

[0030] In this embodiment, fitting grooves are provided on both sides of the die-cutting block, and fitting protrusions adapted to the fitting grooves are machined on both sides of the guide block. The fitting protrusions can be embedded in the fitting grooves to achieve pre-positioning of the two. At the same time, fixing holes are provided at the four corners of the die-cutting block and the guide block. By passing fasteners such as bolts through the fixing holes, the die-cutting block and the guide block can be firmly connected to ensure the stability of their relative positions during the die-cutting process.

[0031] Specifically, it also includes a feed rail 20 and a discharge rail 21 that are respectively connected to both ends of the product conveying rail. The feed rail 20 is provided with a feed drive 22 on one side for pushing the product fed from the feed rail into the product conveying rail, and the discharge rail is provided with a discharge drive 23 on one side for pushing the product coming out of the product conveying rail into the discharge rail.

[0032] In this embodiment, a feeding rail and a discharging rail are respectively connected to both ends of the product conveying rail. A feeding drive (such as a cylinder or electric push rod) is installed on one side of the feeding rail, which can push the product on the feeding rail into the product conveying rail. A corresponding discharging drive is provided on one side of the discharging rail, which can push the film-coated product on the product conveying rail into the discharging rail, thereby realizing automatic product feeding and discharging.

The drive shaft and the driven shaft are connected by a belt drive.

[0034] In this embodiment, a winding motor is mounted on the winding support plate, and the output end of the motor is connected to the drive shaft. A pressure roller assembly and a driven shaft are also provided on the winding support plate. The driven shaft is fixed to the winding support plate via a connecting plate, and the drive shaft and the driven shaft are driven by a belt (not shown in the figure). During operation, the winding motor drives the drive shaft to rotate, and the drive shaft drives the driven shaft to rotate synchronously via the belt. The die-cut waste material is guided by the pressure roller assembly and then wound onto the recycling disc of the driven shaft for recycling.

[0035] Specifically, the pressure roller assembly includes a column 29 fixed on the take-up support plate, a horizontal plate 30 fixed on the column, a telescopic shaft 32 that telescopically engages with the telescopic hole 31 on the horizontal plate 30, and a pressure roller 33 disposed on the top of the telescopic shaft. A pre-tensioning spring (not shown in the figure) is fitted between the horizontal plate and the pressure roller.

[0036] In this embodiment, the elasticity of the pre-tension spring allows the pressure roller to automatically adjust the pressure according to the thickness of the waste material, always maintaining a close fit with the waste material. This avoids insufficient tension or excessive compression caused by fluctuations in the thickness of the waste material, ensuring winding stability, adapting to the winding requirements of waste materials of different thicknesses, and improving the versatility of the pressure roller assembly.
