Description

TECHNICAL FIELD

[0002] In many manufacturing fields such as electronic products, automobiles, medical devices, die cutting processing is a widely used key technology. Die cutting processing mainly uses die cutting machines and die cutting tools to cut various materials (such as foam, double-sided tape, film, rubber, metal foil, etc.) according to the predetermined shape to obtain the required parts. These parts usually need to be laminated by multiple layers of materials to meet the performance requirements of the final product.

[0003] The traditional material lamination method mainly relies on manual or simple mechanical devices. For example, foam, double-sided tape and other materials are manually laminated on the main material belt, and then cut. This method has many defects:

[0004] Low production efficiency: manual lamination is slow and prone to lamination position deviation, which needs to be adjusted repeatedly, seriously affecting production efficiency.

[0005] Unstable product quality: manual lamination cannot guarantee the consistency of lamination pressure, which can easily cause deformation, wrinkles or displacement of flexible materials such as foam, affecting the quality and appearance of the final product. Especially for thick and soft materials such as foam, permanent deformation is likely to occur due to uneven stress during lamination.

[0006] Poor lamination accuracy, prone to glue overflow, poor lamination and other problems: manual lamination cannot accurately control the lamination position and pressure, especially for multi-layer material lamination, which is prone to glue overflow, poor lamination, material suspension and other problems, resulting in increased product failure rate.

[0007] Material scratching problem: In the traditional lamination process, friction between the material and the equipment parts can easily cause material surface scratching, affecting product appearance and performance. INVENTION CONTENTS

BRIEF DESCRIPTION OF DRAWINGS

[0022] Figure 1 The overall structure of the foam bonding device for die cutting processing is shown in the figure. DETAILED DESCRIPTION

[0023] Embodiment

[0024] Please refer to Figure 1 The embodiment provides a foam bonding device for die cutting processing, which comprises:

[0025] The first station comprises a bottom roller shaft 2 and an adjustable bonding rod 3.

[0026] The second station comprises a cutting circular knife roller 4.

[0027] The third station comprises a bonding top roller, a bonding bottom roller 12, a first movable pressing roller 7, a second movable pressing roller 8, a driven gear 9, a bonding bottom roller gear 10 and a knife rest 6.

[0028] The first station is mainly responsible for bonding the foam to the main material belt 1. The main material belt 1 is wound around the bottom roller shaft 2, which is driven to rotate by a servo motor, thereby driving the main material belt 1 to forward convey. The adjustable bonding rod 3 is arranged above the bottom roller shaft 2 and is used to press the foam onto the main material belt 1.

[0029] The adjustable bonding rod 3 can move up and down, and by adjusting its height, the bonding pressure can be changed. This design can reduce the bonding pressure and avoid adverse phenomena such as deformation, wrinkles and displacement of the foam caused by excessive pressure.

[0030] The second station is located downstream of the first station (the next process), and is mainly responsible for cutting and shaping the foam. The cutting circular knife roller 4 is driven to rotate by a servo motor, and when the main material belt 1 with foam passes through the second station, the cutting circular knife roller 4 cuts the predetermined shape on the foam. After cutting, the outer frame waste is discharged, forming a foam cutting product 5.

[0031] The third station, located downstream of the second station, is primarily responsible for applying double-sided adhesive to the main material strip 1 containing the foam-cut finished product 5. The third station includes a top bonding roller, a bottom bonding roller 12, a first movable pressing roller 7, a second movable pressing roller 8, a driven gear 9, a bottom bonding roller gear 10, and a die rest 6. The top bonding roller is positioned above the bottom bonding roller 12. The die rest 6 is fixedly mounted on the top bonding roller. Under high-speed stamping, the stamped product needs to quickly eject from the die for the next stamping cycle, while simultaneously protecting the die.

[0032] The first movable pressing roller 7 and the second movable pressing roller 8 are slidably mounted on the bonding top roller and can move left and right according to the pressing edge position of the product. When the main material belt 1 carrying the foam-cut finished product 5 passes through the third station, the first movable pressing roller 7 and the second movable pressing roller 8 press the double-sided adhesive onto the main material belt 1. Due to the presence of the foam area, the movable pressing rollers can move to avoid the foam area and only press the other areas that need to be bonded with double-sided adhesive, thereby achieving complete bonding of the double-sided adhesive and preventing the material from being suspended.

[0033] Driven gear 9 is located at the shaft end of the bonding top roller, and bonding bottom roller gear 10 is located at the shaft end of the bonding bottom roller 12. Driven gear 9 meshes with bonding bottom roller gear 10, causing the bonding top roller and bonding bottom roller 12 to rotate synchronously. This design can avoid material scratches caused by speed differences. The bonding bottom roller 12 is controlled to rotate by the equipment's servo motor, thereby driving the bonded material belt 11 forward.

[0034] Working principle:

[0035] The working principle of the material bonding device for die-cutting processing of the present invention is as follows:

[0036] The main material belt 1 is wound around the bottom roller shaft 2 of the first station and conveyed forward under the drive of the servo motor.

[0037] The foam is placed on top of the main material strip 1, and the foam is attached to the main material strip 1 by the adjustable bonding rod 3.

[0038] The main material belt 1 with foam enters the second station, where the cutting circular roller 4 cuts out the predetermined shape on the foam to form the finished foam product 5.

[0039] The main material belt 1 with the foam cut finished product 5 enters the third station. The movable pressing rollers 7 and 8 press the double-sided adhesive onto the main material belt 1, avoiding the area of ​​the foam cut finished product 5.

[0040] The laminated material strip 11 is driven by the laminating bottom roller 12 and continues to be conveyed forward.

[0041] Further, the application also comprises three servo motors, which respectively drive the bottom roller shaft 2, the cutting circular knife roller 4 and the laminating bottom roller 12. The three servo motors operate synchronously and in the same direction to ensure the coordinated operation of the whole device.

[0042] The laminating device realizes the laminating, cutting and laminating of double-sided adhesive tape of the foam through the coordinated work of the three work stations, effectively solves the problems of easy deformation, wrinkle, overflow, poor lamination and material scratch of the foam in the prior art, and improves the efficiency of die cutting processing and product quality.

[0043] Finally, it should be pointed out that the above examples are only used to illustrate the technical solutions of the application and are not limiting. Although the application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the application can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the application, which should be covered in the scope of the claims of the application.
