Description

Technical Field

[0001] This utility model belongs to the field of lithium battery production technology, and in particular relates to a peeling blade structure and a double-sided adhesive separation device. Background Technology

[0002] Double-sided tape is a common type of adhesive tape, sticky on both sides, and widely used in the packaging industry. Double-sided tape has a protective film layer, which needs to be separated from the backing paper during use. The principle of peeling double-sided tape is that the backing paper moves around the peeling blade, and when the double-sided tape approaches the peeling blade, a suction cup separates the double-sided tape from the backing paper.

[0003] However, most existing peeling blade structures have a chamfered edge to ensure the backing paper can smoothly bypass the blade and enter the next process. Regarding the peeling effect of double-sided adhesive, when the double-sided adhesive approaches the blade, the suction cup separates the adhesive from the backing paper; however, as the backing paper flows down around the blade, the closer the double-sided adhesive is to the blade, the greater the damage to the adhesive; therefore, the double-sided adhesive is not completely peeled off, resulting in poor peeling effect and low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a peeling blade structure that addresses the shortcomings of existing technologies and solves the technical problem of poor peeling effect in existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A peeling blade structure includes a blade body; a peeling component is provided on a surface of the blade body along a first direction; a guide arc surface is also provided on the surface of the blade body along the first direction.

[0007] Preferably, the blade body includes a support and conveying section and a peeling blade section connected to each other; the peeling component and the guide arc surface are sequentially disposed on the surface of the peeling blade section along a first direction.

[0008] Preferably, the bottom of the peeling blade section is provided with a guide slope; the top of the guide slope is connected to the bottom of the guide arc surface;

[0009] The angle between the guiding inclined plane and its horizontal plane is α; α satisfies: 30°≤α≤50°.

[0010] Preferably, the peeling component is a peeling groove; the peeling groove is recessed from the surface of the blade body toward the interior of the blade body.

[0011] Preferably, the number of the peeling grooves is at least two, and all the peeling grooves are arranged side by side along a direction perpendicular to the first direction.

[0012] Preferably, the number of the peeling grooves is at least two, and all the peeling grooves are arranged side by side along the first direction.

[0013] Preferably, the distance between two adjacent peeling grooves is M, where M satisfies: 0.040mm≤M≤0.050mm.

[0014] Preferably, the depth of each of the peeling grooves is H; H satisfies: 0.0030mm≤H≤0.0040mm.

[0015] Preferably, the radius of the guide arc surface is r; r satisfies: 0.20mm≤r≤0.50mm.

[0016] This utility model also discloses a double-sided adhesive separation device, including the aforementioned peeling blade structure.

[0017] The beneficial effects of this utility model are as follows: This technical solution uses the guide arc surface to guide and transport the double-sided adhesive in an arc shape, ensuring that the double-sided adhesive can pass smoothly through the blade body; and combined with the added peeling component, without affecting the movement of the double-sided adhesive, the dual structure of the peeling component and the guide arc surface further increases the frictional resistance between the backing paper of the double-sided adhesive and the blade body, thereby increasing the contact stress between the adhesive layer of the double-sided adhesive and the backing paper, which in turn facilitates the peeling of the adhesive layer of the double-sided adhesive from the backing paper, improving the peeling effect and efficiency.

[0030] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0031] like Figure 1 and 3As shown, in one embodiment of this utility model, the peeling blade structure includes a blade body 1; a peeling component 2 is provided on the surface of the blade body 1 along a first direction; and a guide arc surface 3 is also provided on the surface of the blade body 1 along the first direction. The first direction is the conveying direction AB of the double-sided adhesive 4.

[0032] The technical solution of this utility model uses a guide arc surface to guide and transport the double-sided adhesive in an arc shape, ensuring that the double-sided adhesive can pass smoothly through the blade. In addition, the added peeling component, without affecting the movement of the double-sided adhesive, achieves a dual structure of peeling component and guide arc surface, further increasing the frictional resistance between the backing paper of the double-sided adhesive and the blade, thereby increasing the contact stress between the adhesive layer 41 of the double-sided adhesive and the backing paper, which in turn facilitates the peeling of the adhesive layer 41 of the double-sided adhesive from the backing paper, improving the peeling effect and efficiency.

[0033] Specifically, in some implementations, such as Figure 1 and 2 As shown, the blade body 1 includes a support and conveying section 11 and a peeling blade section 12 connected as a single unit; the peeling component 2 and the guide arc surface 3 are sequentially disposed on the surface of the peeling blade section 12 along the conveying direction AB of the double-sided adhesive 4. This structure, through the sequentially disposed peeling component 2 and guide arc surface 3, enhances the frictional resistance between the backing paper and the peeling blade section 12 before the backing paper of the double-sided adhesive smoothly slides down, resulting in greater damage between the double-sided adhesive and the backing paper when it approaches the peeling blade section 12, which is more conducive to the peeling of the double-sided adhesive and improves the peeling efficiency.

[0034] Specifically, in some implementations, such as Figure 4 As shown, the bottom of the peeling blade section 12 is provided with a guide slope 121; the top of the guide slope 121 is connected to the bottom of the guide arc surface 3; wherein, the angle between the guide slope 121 and its horizontal plane is α; α satisfies: 30°≤α≤50°. This structure, through the guide slope 121 with a relatively small inclination angle, can ensure the smooth delivery of double-sided adhesive, thereby improving peeling efficiency.

[0035] Specifically, in some implementations, such as Figure 1 and 2 As shown, the peeling component 2 uses at least one peeling groove 21; the peeling groove 21 is recessed from the surface of the blade body 1 (middle peeling blade section 12) along the conveying direction AB of the double-sided adhesive 4 towards the interior of the blade body 1 (middle peeling blade section 12). That is, this structure enhances the frictional resistance between the backing paper and the peeling blade section 12 by adding the recessed peeling groove 21, resulting in greater damage between the double-sided adhesive and the backing paper when it approaches the peeling blade section 12, which is more conducive to the peeling of the double-sided adhesive and improves the peeling efficiency; furthermore, the peeling groove 21 improves processing convenience and ensures smooth conveying of the double-sided adhesive 4. Further, in some embodiments, such as... Figure 2 As shown, the number of peeling grooves 21 is at least two, and all peeling grooves 21 are arranged side by side along a direction perpendicular to the conveying direction AB of the double-sided adhesive 4. In other embodiments, such as Figure 5 As shown, there are at least two peeling grooves 21, and all peeling grooves 21 are arranged side by side along the conveying direction AB of the double-sided adhesive 4. This structure can increase the peeling friction from different directions, thereby enhancing the frictional resistance between the backing paper and the peeling blade section 12. This results in greater damage between the double-sided adhesive and the backing paper when it approaches the peeling blade section 12, which is more conducive to the peeling of the double-sided adhesive and improves the peeling efficiency of the double-sided adhesive.

[0036] Specifically, in some implementations, such as Figure 2 and 3 As shown, the distance between two adjacent peeling grooves 21 is M, where M satisfies: 0.040mm ≤ M ≤ 0.050mm; it can be 0.046mm, 0.047mm, 0.048mm, etc., preferably 0.046mm. This structure, with peeling grooves 21 of appropriate distance difference, ensures greater damage between the double-sided adhesive and the backing paper when it is close to the peeling blade section 12, thus facilitating the peeling of the double-sided adhesive and improving the peeling efficiency.

[0037] Specifically, in some implementations, such as Figure 3 and 4 As shown, the depth of each peeling groove 21 is H; H satisfies: 0.0030mm ≤ H ≤ 0.0040mm; it can be 0.0031mm, 0.0032mm, 0.0033mm, 0.0034mm, 0.0035mm, 0.0036mm, 0.0037mm, 0.0038mm, 0.0039mm, and 0.0040mm, etc. Preferably, it is 0.0035mm. This structure, with peeling grooves 21 of appropriate depth, ensures greater damage between the double-sided adhesive and the backing paper near the peeling blade section 12, thus facilitating smoother peeling and conveying of the double-sided adhesive and improving peeling efficiency.

[0038] Specifically, in some implementations, such as Figure 3 and 4 As shown, the radius of the guide arc surface 3 is r; r satisfies: 0.20mm ≤ r ≤ 0.50mm; it can be 0.20mm, 0.25mm, 0.30mm, 0.35mm, 0.40mm, and 0.50mm, etc. Preferably, it is 0.30mm. This structure, through the guide arc surface 3 with a suitable radius, ensures smooth conveying and improves the peeling efficiency of the double-sided adhesive.
