Technical Field

[0001] This utility model relates to the field of OCA film slitting technology, and in particular to a precision cutting device for OCA film cutting. Background Technology

[0002] Typically, during the production and processing of OCA films, a precision cutting device is required to cut the OCA film to the required size, enabling the film to be cut with high precision and efficiency.

[0003] When cutting, OCA films are usually cut using methods such as laser cutting, blade cutting, water jet cutting, and ultrasonic cutting. Blade cutting involves physically cutting the OCA film using blades or rollers, and this method is often used for large-scale production of thicker OCA films.

[0004] In order to ensure the cutting accuracy of the film during the cutting process, an adsorption device or clamp is usually used to fix the position of the film. During the fixing process, the adsorption device or clamp applies uneven pressure to the film, especially when the film is thin or soft, which can cause local deformation or indentation of the film, affecting the cutting quality and subsequent use of the film. Therefore, a precision cutting device for OCA film cutting is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a precision cutting device for OCA membrane cutting, which aims to improve the problem in the prior art where, during the cutting process, using an adsorption device or clamp to fix the membrane position may cause uneven pressure on the membrane, especially for thinner or softer membranes, resulting in local deformation or indentation of the membrane, thereby affecting the cutting quality and subsequent use of the membrane.

[0031] 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.

[0032] Reference Figure 1 , Figure 3 , Figure 5 This utility model provides an embodiment of a precision cutting device for OCA film cutting, comprising a base 1, a gantry 2 fixedly connected to the outer surface of the base 1, providing fixed support for the gantry 2 via the outer surface of the base 1, a power component at the top of the outer surface of the gantry 2, enabling the power component to drive a tool holder 4 to move vertically, a tool holder 4 slidably connected to the top of the inner surface of the gantry 2, enabling the tool holder 4 to move vertically along the inner surface of the gantry 2, and an arc-shaped plate 5 hinged to the top of the outer surface of the tool holder 4. The arc plate 5 has the effect of expanding or contracting along the top of the outer surface of the tool holder 4. There are two sets of arc plates 5, so that the two sets of arc plates 5 can expand or contract along the top of the outer surface of the tool holder 4 at the same time, so as to fix the two ends of the OCA film. The bottom of the outer surface of the arc plate 5 is rotatably connected to the roller 6, so that when the roller 6 moves, it can drive the arc plate 5 to expand outward. The middle of the outer surface of the arc plate 5 is elastically connected to the middle of the outer surface of the tool holder 4 through the spring 10, so that the arc plate 5 can always maintain the effect of contracting towards the tool holder 4 without the influence of external force.

[0033] Reference Figure 1 The power assembly includes a telescopic motor 3 and a guide column 14. The bottom of the outer surface of the telescopic motor 3 is fixedly connected to the top of the outer surface of the gantry 2, providing a fixed support for the telescopic motor 3 through the top of the outer surface of the gantry 2. The output end of the telescopic motor 3 is fixedly connected to the top of the outer surface of the tool holder 4, enabling the telescopic motor 3 to drive the tool holder 4 to move vertically. The bottom of the outer surface of the guide column 14 is fixedly connected to the top of the outer surface of the tool holder 4, enabling the tool holder 4 to move along with the guide column 14 when moving vertically. The outer surface of the guide column 14 is slidably connected to the top of the inner surface of the gantry 2, allowing the guide column 14 to move vertically along the top of the inner surface of the gantry 2, so that the tool holder 4 can always maintain the movement along the specified position and direction.

[0034] Reference Figure 2 - Figure 4The tool holder 4 has a plate 11 fixedly connected to both the front and rear ends of its outer surface, so that when the tool holder 4 moves vertically, it can move the plate 11 together. A traction block 9 is slidably connected to the bottom end of the inner surface of the plate 11, so that the traction block 9 can move vertically along the bottom end of the inner surface of the plate 11. A telescopic hinge rod 7 is hinged to the bottom end of the traction block 9, so that when the traction block 9 moves vertically, it can move the telescopic hinge rod 7 together. The middle part of the inner surface of the telescopic hinge rod 7 is rotatably connected to the middle part of the outer surface of the front end of the base 1, so that the telescopic hinge rod 7 can rotate along the front end of the outer surface of the base 1. A connecting column 15 is hinged to the bottom end of the telescopic hinge rod 7, so that when the telescopic hinge rod 7 is rotated by the traction block 9, it can move the connecting column 15 vertically. An ejector plate 8 is fixedly connected to the rear end of the outer surface of the connecting column 15, so that when the connecting column 15 moves vertically, it can move the ejector plate 8 vertically.

[0035] Refer to Figure 3- Figure 5 The outer surface of the roller 6 contacts the top of the outer surface of the ejector plate 8, so that when the roller 6 moves downward under the drive of the tool holder 4, it can move outward along the top of the ejector plate 8 due to the contact connection, thus fixing the OCA film in a designated position. The outer surface of the ejector plate 8 is slidably connected to the middle of the inner surface of the base 1, so that the ejector plate 8 can move vertically along the middle of the inner surface of the base 1. When the ejector plate 8 extends out of the base 1, it can simultaneously abut against the bottom end of the OCA film, keeping the OCA film in a taut state during cutting and preventing local deformation of the film during cutting. A cutting groove is opened at the top of the outer surface of the ejector plate 8, so that the tool 13 will not contact the top of the ejector plate 8 when cutting the film, thus preventing damage to the tool 13. One end of the spring 10 is connected to the middle of the outer surface of the arc plate 5. The spring 10 is fixedly connected to the middle of the outer surface of the tool holder 4. When the tool holder 4 rises, it will drive the arc plate 5 to rise together. When the roller 6 at the bottom of the arc plate 5 stops pressing the top of the ejector plate 8, the two sets of arc plates 5 will retract inward and reset due to the elastic force of the spring 10. The bottom of the inner surface of the plate 11 is fixedly connected to the column 12, so that the plate 11 can drive the column 12 to move together. The top of the inner surface of the traction block 9 is provided with a sliding groove, so that the column 12 can move vertically along the top of the inner surface of the traction block 9. The outer surface of the column 12 is slidably connected to the inner surface of the sliding groove. When the plate 11 drives the column 12 to move upward, when the column 12 moves to the top of the sliding groove, it will drive the traction block 9 to move upward. When the column 12 moves to the bottom of the sliding groove, it will drive the traction block 9 to move downward.

[0036] Reference Figure 3 , Figure 5The bottom of the inner surface of the tool holder 4 is fixedly connected to an electric slide rail, which provides a fixed support for the electric slide rail. Since the electric slide rail is existing technology, it consists of components such as a sliding track, a motor, and a threaded rod. Its internal structure will not be described in detail here. The tool 13 is slidably connected to the inner surface of the electric slide rail, so that the tool 13 can move laterally under the drive of the electric slide rail. The outer surface of the tool 13 is slidably connected to the inner surface of the cutting groove, so that the tool 13 can move laterally along the inner surface of the cutting groove and cut the OCA film. The top of the outer surface of the ejector plate 8 is set as an arc surface, so that when the roller 6 contacts the top of the ejector plate 8, it can move outward. The ejector plate 8 can also push the OCA film out to form a protrusion, preventing indentations during ejection.

[0037] Working principle: When using the device, first pass the OCA film through the bottom of the cutter holder 4 from one end of the base 1 to the other end. After determining the cutting length, start the telescopic motor 3 to drive the cutter holder 4 downwards. This causes the rollers 6 at the bottom of the two sets of arc-shaped plates 5 to contact the top surface of the OCA film. The two sets of rollers 6 then roll the arc-shaped plates 5 outwards along both sides of the OCA film, fixing the OCA film in place and preventing it from moving left or right during cutting. As the cutter holder 4 moves downwards, it also drives the two sets of plates 11 downwards simultaneously. When the plate 11 moves downward, it will drive the column 12 at the bottom of the inner surface of the plate 11 to move downward along the slide groove at the top of the traction block 9. When the column 12 moves to the bottom of the slide groove, it will drive the traction block 9 to move downward together, and at the same time drive the two sets of telescopic hinge rods 7 to rotate along the outer surface of the base 1. The ejector plate 8 will move upward due to the drive of the two sets of telescopic hinge rods 7, lifting the area of ​​the OCA film to be cut to form an arc surface, so that the film is in a taut state. Then the electric guide rail is started, which drives the cutter 13 to move quickly laterally and cut the film.

[0038] After cutting is completed, the telescopic motor 3 is started, which drives the tool holder 4 to move upward, so that the two sets of arc plates 5 are no longer squeezed by the roller 6 against the ejector plate 8. The two sets of arc plates 5 retract inward and reset due to the elastic force of the spring 10. When the tool holder 4 moves upward, the plate body 11 also drives the column body 12 to move upward, so that the column body 12 moves to the top of the groove on the traction block 9, which drives the traction block 9 to move upward. When the traction block 9 moves upward, it will simultaneously drive the two sets of telescopic hinge rods 7 to rotate along the outer surface of the base 1, which will drive the ejector plate 8 to move downward and engage with the base 1 to reset.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
