Description

Technical Field

[0001] The utility model relates to the technical field related to label stripping machinery, in particular to a coiled Mylar stripping device. Background Art

[0002] Mylar sheet is primarily used in the electrical insulation industry, serving as gaskets, retaining plates, screens, and protective materials for electronics, household appliances, instruments, displays, motor slots, computers, and peripheral equipment. It is an insulating material used for insulating motors, capacitors, coils, and cables. Common Mylar products include PET Mylar sheet, screen Mylar sheet, and transparent Mylar sheet. Each has specific application areas and characteristics. For example, the excellent heat resistance and dimensional stability of PET Mylar sheet, and the polyester material and exceptional tensile properties of transparent Mylar sheet, make them widely used in various industries.

[0003] The preparation of Mylar sheets generally involves first cutting the Mylar material into sheets by die-cutting, and then peeling it off from the base film. However, for Mylar rolls that are extremely soft, sticky, and not completely separated, it is difficult to use an automated peeling mechanism to automatically peel the base film from the Mylar. The difficulties faced include: (1) Due to the high viscosity of the Mylar material, it is difficult to separate the Mylar sheet from the base film after die-cutting; (2) After the Mylar sheet is separated from the base film, the softness of the material causes the Mylar sheet to sag and cannot be removed; (3) Due to the high viscosity of the Mylar sheet obtained after die-cutting, adjacent Mylar sheets will stick together again after die-cutting, which makes it extremely difficult to remove the Mylar sheet by suction. Utility Model Content

[0004] The utility model aims to provide a Mylar stripping device for a roll material, aiming to solve the problem of stripping Mylar strips with soft and extremely high viscosity.

[0005] In order to solve the above technical problems, the utility model provides a roll material Mylar stripping device, which includes an unwinding mechanism, a tensioning mechanism, a Mylar stripping mechanism and a base film winding mechanism;

[0006] The unwinding mechanism is used to install the coiled Mylar material, and the coiled Mylar material includes a base film and a die-cut Mylar sheet adhered to the base film;

[0007] The tensioning mechanism is arranged between the unwinding mechanism and the Mylar stripping mechanism, and is used for tensioning the coiled Mylar material;

[0008] The bottom film winding mechanism is used to wind up the bottom film material after peeling off the Mylar sheet;

[0009] The Mylar peeling mechanism is used to peel the Mylar sheet from the base film. The Mylar peeling mechanism includes a peeling knife, a lifting power roller and an adsorption robot. A space for the base film to pass through is formed between the peeling knife and the lifting power roller.

[0010] Furthermore, the stripping knife includes a bottom film supporting surface and a front end discharge port, and the front end discharge port is inclined downward relative to the bottom film supporting surface.

[0011] Furthermore, the base film moves downward around the front end discharge port and is connected to the base film winding mechanism. The lifting power roller rotates clockwise to approach the front end of the Mylar sheet on the base film, driving the Mylar sheet to move upward and then separate from the base film, thereby realizing the separation of the Mylar sheet and the base film.

[0012] Furthermore, the linear speed of rotation of the lifting power roller is 1.1-1.2 times the moving speed of the base film.

[0013] Furthermore, when the lifting power roller is peeling the Mylar sheet, the distance between the side of the lifting power roller close to the front end discharge port and the front end discharge port is 1 mm-2 mm.

[0014] Furthermore, the Mylar peeling mechanism further includes a connecting rod bracket structure, and the connecting rod bracket structure is used to support the Mylar sheet after being peeled off from the base film.

[0015] Furthermore, the connecting rod bracket structure includes a connecting rod driving structure and a front roller arranged at the front end of the connecting rod driving structure.

[0016] Furthermore, the bottom film winding mechanism includes a bottom film winding drum and a clamping roller arranged between the bottom film winding drum and the Mylar peeling mechanism.

[0017] The implementation of the present invention will have the following beneficial effects:

[0018] 1. The coiled Mylar stripping device disclosed herein uses a lifting power roller in conjunction with a stripping blade to separate the Mylar sheet from the base film. Specifically, the lifting power roller is raised so that the distance between the side closest to the front discharge port and the front discharge port is 1mm-2mm, facilitating the passage of the base film. At the same time, the clockwise rotating lifting power roller approaches the front end of the Mylar sheet, driving the Mylar sheet upward and away from the base film. This solves the problem of difficulty separating the die-cut Mylar sheet from the base film due to the high viscosity of the Mylar material.

[0019] 2. This application sets up a connecting rod bracket structure to lift the peeled Mylar sheet so that the Mylar sheet is in a horizontal state, which is convenient for the adsorption robot to adsorb and pick up the material. It solves the problem that after the Mylar sheet is separated from the bottom mold, the Mylar sheet sags due to the softness of the material and cannot be picked up.

[0024] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please refer to Figure 1-2 The embodiment of the present invention provides a roll-to-roll Mylar stripping device, which includes an unwinding mechanism 3, a tensioning mechanism 4, a Mylar stripping mechanism and a base film winding mechanism 5.

[0028] The unwinding mechanism 3 is used to install the Mylar material roll, which includes a base film 1 and a die-cut Mylar sheet 2 adhered to the base film 1. A blank section is reserved at the front end of the base film 1. This reserved blank section facilitates the initial installation of the Mylar material roll (i.e., the front end of the base film 1 is connected to the base film rewinding mechanism 5 after passing through the tensioning mechanism 4 and the Mylar stripping mechanism). This prevents the first Mylar sheet on the front end of the base film 1 from being located behind the Mylar stripping mechanism after initial installation, preventing the first Mylar sheet from being completely stripped. Specifically, the reserved blank section is generally 400 mm long and can be adaptively adjusted based on the actual layout of the stripping equipment.

[0029] The tensioning mechanism 4 is arranged between the unwinding mechanism 3 and the Mylar stripping mechanism and is used to tension the coiled Mylar material. The tensioning mechanism 4 can be a tensioning roller or a tensioning wheel. The number of tensioning rollers or tensioning wheels is not limited to one and can be set based on actual conditions. The tensioning mechanism 4 ensures that the coiled Mylar material unwound from the unwinding mechanism 3 is in a tensioned state when entering the stripping station to facilitate stripping of the Mylar sheet. The tensioning mechanism 4 is a common structure in the art and will not be described in detail here.

[0030] The bottom film rewinding mechanism 5 is used to rewind the bottom film material after peeling off the Mylar sheet 2. The bottom film rewinding mechanism 5 has a similar structure to the unwinding mechanism 3.

[0031] The Mylar peeling mechanism is used to peel the Mylar sheet 2 from the base film 1. The Mylar peeling mechanism includes a peeling blade, a lifting power roller 9, and an adsorption robot 6. A space is formed between the peeling blade and the lifting power roller 9 for the base film 1 to pass through. In other words, after the Mylar sheet 2 is peeled off, the base film 1 moves downward through the space formed between the peeling blade and the lifting power roller 9, while the Mylar sheet 2 moves upward, achieving separation between the Mylar sheet 2 and the base film 1.

[0032] In another specific embodiment, the stripping blade includes a base film support surface 8 and a front discharge port 7, wherein the front discharge port 7 is inclined downward relative to the base film support surface 8. The base film support surface 8 is used to support the base film 1. The base film 1 with the Mylar sheet 2 bonded thereto moves forward through the base film support surface 8 into the front discharge port 7, and the Mylar sheet 2 is peeled off from the base film 1 at the front discharge port 7.

[0033] In another specific embodiment, the base film 1 moves downward around the front end discharge port 7 and is connected to the base film winding mechanism 5. The lifting power roller 9 rotates clockwise to approach the front end of the Mylar sheet 2 on the base film 1, driving the Mylar sheet 2 to move upward and then separate from the base film 1, thereby realizing the separation of the Mylar sheet 2 from the base film 1.

[0034] In another specific embodiment, the linear speed of the lifting roller 9 is greater than the forward movement speed of the base film 1, forming a differential motion, thereby achieving rapid peeling of the Mylar sheet 2 and preventing the Mylar sheet 2 from moving downward with the base film 1. Specifically, the linear speed of the lifting roller 9 is 1.1-1.2 times the forward movement speed of the base film 1.

[0035] In another specific embodiment, when the lifting power roller 9 is peeling the Mylar sheet 2, the distance between the side of the lifting power roller 9 close to the front end discharge port 7 and the front end discharge port 7 is 1mm-2mm. Specifically, this distance value is determined according to the thickness of the base film 1 and cannot be too large or too small. If it is too large, the lifting power roller 9 cannot reach the Mylar sheet 2 and the Mylar sheet 2 cannot be peeled off. If it is too small, the base film 1 after peeling the Mylar sheet 2 cannot move downward through the space to separate the Mylar sheet 2 from the base film 1.

[0036] In another specific embodiment, the Mylar peeling mechanism further includes a connecting rod bracket structure 10, which is used to support the Mylar sheet 2 after being peeled off from the base film 1. As mentioned in the background technology, after the Mylar sheet 2 is separated from the base mold 1, the Mylar sheet 2 sags due to the softness of the material of the Mylar sheet 2, making it impossible to complete the material removal. Therefore, it is necessary to add a connecting rod bracket structure 10 to support the Mylar sheet 2 after being peeled off from the base film 1 to prevent the Mylar sheet 2 from sagging, thereby facilitating the suction and material removal by the suction robot 6.

[0037] In another specific embodiment, the connecting rod bracket structure 10 includes a connecting rod drive structure 11 and a front roller 12 disposed at the front end of the connecting rod drive structure 11. The connecting rod drive structure 11 can drive the front roller 12 to move in the front-to-back direction and the up-down direction. After the lifting power roller 9 peels off the Mylar sheet 2, the lifting power roller 9 moves downward to make room; then the connecting rod drive structure 11 drives the front roller 12 to move downward and extend forward into the lower part of the Mylar sheet 2 that has been peeled off, so that the front roller 12 can support the Mylar sheet 2. Afterwards, the connecting rod drive structure 11 drives the front roller 12 to move upward, so that the Mylar sheet 2 remains in a horizontal state, so that the adsorption robot 6 can adsorb the Mylar sheet 2 to complete the material removal work.

[0038] In another specific embodiment, after the adsorption robot 6 adsorbs the Mylar sheet 2, it moves downward in accordance with the trend. As mentioned in the background art, the Mylar sheet 2 obtained after die-cutting is highly viscous, and adjacent Mylar sheets 2 after die-cutting will stick together again, which makes it extremely difficult to remove the Mylar sheet 2 using the adsorption method. Therefore, in this solution, after the adsorption robot 6 adsorbs the Mylar sheet 2, it moves downward in accordance with the trend, completely cutting the connection with the adjacent Mylar sheet 2 and completing the material removal.

[0039] In another specific embodiment, the base film winding mechanism 5 includes a base film winding drum and a pinch roller (not shown) disposed between the base film winding drum and the Mylar stripping mechanism. The pinch roller serves as a power mechanism for moving the base film 1, and can drive the base film 1 forward to achieve uninterrupted stripping of the Mylar sheet 2.

[0040] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
