Description

Technical Field

[0001] This utility model relates to the technical field of machining tools, and more specifically, to a film-peeling workpiece. Background Technology

[0002] Traditional double-sided adhesive film removal from notebook cartons has long relied on manual operation, which presents three major technical challenges: First, manual peeling is inefficient and repetitive, easily leading to operator fatigue; second, traditional film-picking methods pose a safety hazard of blade cuts to the hands; and third, manual operation makes it difficult to precisely control the film-removing angle and force, easily causing film breakage or residue.

[0003] The commonly used film-tearing tools in the prior art are hook-shaped film-picking pieces and clamping film-tearing pliers. Although these two film-tearing tools can achieve initial film lifting, their single-point force structure cannot effectively fix the tearing area of ​​the double-sided adhesive film. As a result, during the process of tearing the release film of the double-sided adhesive film, another hand is needed to assist in fixing the double-sided adhesive film to be torn, and the film-tearing operation is not continuous. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a film-peeling workpiece that can peel off the release film from the surface of double-sided adhesive, in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a film-tearing workpiece, comprising a main body; the main body is provided with a fixing part and a film-lifting angle; the tip of the film-lifting angle extends toward the fixing part; the main body is provided with an air-avoiding groove for temporary storage of waste film between the fixing part and the film-lifting angle; the tip of the film-lifting angle is not higher than the pressing surface of the fixing part;

[0006] In the film-tearing workpiece of this utility model, the height difference between the pressing surface of the fixing part and the lower surface of the film-raising angle is not greater than 0.4mm;

[0007] The film-peeling workpiece of this utility model has a film-forming angle that is an inverted V-shaped pointed cone structure.

[0008] In the film-tearing workpiece described in this utility model, the upper surface of the film-raising angle is a first inclined surface that slopes downward and towards the pressing surface.

[0009] In the film-tearing workpiece of this utility model, the surface of the fixing part facing the film-raising angle is a second inclined surface that is downward and inclined towards the pressing surface.

[0010] In the film-tearable workpiece described in this utility model, the inclination angle of the second inclined surface is greater than the inclination angle of the first inclined surface.

[0011] In the film-tearable workpiece of this utility model, the first inclined surface, the second inclined surface, and the meandering curved surface connecting the first inclined surface and the second inclined surface enclose each other to form the clearance groove;

[0012] The film-tearing workpiece of this utility model includes a middle plane parallel to the pressing surface and two third inclined planes symmetrically arranged on both sides of the middle plane; both third inclined planes are inclined downwards and toward the middle plane.

[0013] The film-peeling workpiece of this utility model has a main body in the form of a rectangular block structure; the film-peeling angle and the fixing part are both located on the lower surface of the main body, and the central axis of the film-peeling angle overlaps with the central axis of the fixing part; the tip of the film-peeling angle is located on the intermediate plane.

[0014] The film-tearing workpiece of this utility model has a fourth inclined surface on the lower front side of the main body, which is downward and inclined toward the film-forming angle.

[0015] The beneficial effects of this utility model are as follows: The structure of the film-tearing workpiece is simple and ingeniously designed. During use, the fixing part fixes the double-sided adhesive film to be peeled and provides a stable force fulcrum. Combined with the tip guide structure of the film-lifting corner, when peeling the film, pressing and moving the main body with one hand can fix the double-sided adhesive film to be peeled and simultaneously lift the film, without the need for additional auxiliary operations, which greatly improves the continuity of the operation. The tip of the film-lifting corner is not higher than the pressing surface of the fixing part, which can ensure that the film can be lifted smoothly and then the release film can be peeled off. The anti-cavity groove serves as a temporary storage space for waste film, which automatically collects part of the peeled release film during the film-tearing process, preventing the waste film from scattering or re-adheding to the double-sided adhesive, ensuring the cleanliness and efficiency of continuous operation.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0024] This utility model provides a preferred embodiment of a film-tearing workpiece. This embodiment uses double-sided adhesive film as an example. It is worth noting that the film-tearing workpiece of this utility model is not limited to tearing only double-sided adhesive film; it can also be used to tear material strips with protective films or other material strip structures. For example... Figures 1-2As shown, a film-tearing tool includes a main body 10; the main body 10 is provided with a fixing part 11 and a film-lifting angle 12; the tip of the film-lifting angle 12 extends toward the fixing part 11; the pressing surface of the fixing part serves as the main force fulcrum. In use, the user presses the film-tearing tool onto the end of the double-sided adhesive film to be torn and moves the film-tearing tool along the tearing direction of the double-sided adhesive film. The downward pressure applied by the user is converted into a combined action of vertical fixing force on the double-sided adhesive film and horizontal tearing force on the film-lifting angle, realizing a one-handed "press-tear" integrated action.

[0025] Furthermore, the main body 10 is provided with a clearance groove 13 for temporary storage of waste film between the fixing part 11 and the film-lifting corner 12. During the film-tearing process, the release film peeled off naturally curls into the clearance groove with the tearing action, forming a continuous operation mode of "tearing and collecting at the same time" to prevent the waste film from scattering or re-adhering to the double-sided adhesive; the tip of the film-lifting corner 12 is not higher than the pressing surface 111 of the fixing part 11. It is worth noting that the waste material mentioned in this embodiment is the release film on the double-sided adhesive film.

[0026] This film-removing tool has a simple structure and ingenious design. During use, the fixing part secures the double-sided adhesive film to be removed and provides a stable force fulcrum. Combined with the tip guide structure of the film-removing corner, pressing and moving the main body with one hand can fix the double-sided adhesive film to be removed and simultaneously lift the film, without the need for additional auxiliary operations, greatly improving the continuity of the operation. The tip of the film-removing corner is not higher than the pressing surface of the fixing part, which can ensure smooth film lifting and removal of the release film. The anti-cavity groove serves as a temporary storage space for waste film, automatically collecting some of the peeled release film during the film-removing process, preventing waste film from scattering or re-adheding to the double-sided adhesive, ensuring the cleanliness and efficiency of continuous operation.

[0027] Furthermore, the height difference between the pressing surface 111 of the fixing part 11 and the lower surface of the film-removing angle 12 is no greater than 0.4mm; ensuring that the tip maintains a constant micro-distance contact with the surface of the object to be applied during the film removal process, which not only prevents scratching the substrate, but also allows for precise cutting into the adhesive film interface.

[0028] In this embodiment, the film-removing angle 12 is an inverted V-shaped pointed cone structure, which makes the tearing stress symmetrically distributed along the tip, avoiding the phenomenon that the release film cannot be torn off.

[0029] Furthermore, the upper surface of the film-forming angle 12 is a first inclined surface 121 that slopes downward and towards the pressing surface 111; this allows the tip of the film-forming angle to accurately cut into the adhesive film interface layer at a preset angle during the pressing process, ensuring that the tearing path and the release film peeling direction maintain the best fit, which has the function of guiding the waste film into the anti-cavity groove, and can also avoid adhesive film penetration damage caused by the angle being too small.

[0030] Furthermore, the surface of the fixing part 11 facing the film-lifting angle 12 is a second inclined surface 112 that slopes downwards and towards the pressing surface 111. The inclination angle of the second inclined surface 112 is greater than that of the first inclined surface 121. Optionally, the inclination angle of the first inclined surface is 10°-30°; the inclination angle of the second inclined surface is 35°-45°. The second inclined surface 112 and the first inclined surface 121 form a tapered flow channel, and the peeled release film naturally curls off the double-sided adhesive along the inclined surface under the action of surface tension. Tests show that this design reduces the waste film removal time to within 0.5 seconds and the secondary adhesion rate from 23% to below 1%.

[0031] Furthermore, the first inclined surface 121, the second inclined surface 112, and the meandering curved surface 113 connecting the first inclined surface 121 and the second inclined surface 112 enclose each other to form a clearance groove 13; this clearance groove formed by the enclosement has a Venturi effect-like effect, generating a local negative pressure area during the film peeling process, causing the peeled release film to naturally curl along the first inclined surface 121 and enter the clearance groove, which can effectively prevent the waste film from rebounding and re-adheding.

[0032] Furthermore, the lower surface of the film-removing angle 12 includes a central plane 122 parallel to the pressing surface 111, and two third inclined planes 123 symmetrically arranged on both sides of the central plane 122; both third inclined planes 123 are inclined downwards and toward the central plane 122. The central plane 122 is a visible reference line, and the third inclined planes 123 will not contact the double-sided adhesive film during the film-removing process, which can greatly reduce the contact area of ​​the film-removing angle 12 with the double-sided adhesive after film removal, allowing it to continue to be removed smoothly.

[0033] Alternatively, the main body 10 has a rectangular block structure, which is small in size and easy to hold with one hand; the film-forming corner 12 and the fixing part 11 are both located on the lower surface of the main body 10, and the central axis of the film-forming corner 12 overlaps with the central axis of the fixing part 11; the tip of the film-forming corner 12 is located on the middle plane 122, which has a simple structure and a simple appearance.

[0034] Furthermore, the lower front end of the main body 10 is provided with a fourth inclined surface 114 that slopes downward and toward the film-tearing angle 12. When the user uses it, the user's fingers are placed on the fourth inclined surface, which not only makes it easier for the user to determine the front and back direction of the film-tearing tool and helps to determine the film-tearing direction, but also makes it easier for the fingers to apply a lateral force, which is beneficial for subsequent film tearing.

[0035] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
