Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing and manufacturing technology, and specifically refers to a structure that facilitates the peeling of release paper. Background Technology

[0002] refer to Figure 1 As shown, during the production and processing of circuit board products 1 such as FPC (Flexible Printed Circuit), a layer of release paper 2 is often attached to its surface to cover the double-sided adhesive 3 on the surface of the circuit board product 1, or to protect the circuit part, or to facilitate other processing steps.

[0003] To facilitate the removal of the release paper 2, existing technologies typically incorporate a pull tab 20 on the side of the release paper 2. The main function of the pull tab 20 is to prevent the double-sided adhesive 3 from becoming contaminated and ineffective before use. During use, tweezers can be used to grasp the pull tab 20 to peel off the release paper 2 without damaging the product. The product can then be adhered to a plastic or metal casing using the double-sided adhesive 3. Clearly, manual peeling suffers from low efficiency: current manual peeling methods achieve an efficiency of approximately 500 pieces / hour, or 5000 pieces / day per person. Considering labor intensity and fatigue, this efficiency may not even be achieved. Assuming a factory's daily output is 30,000 pieces, this peeling process alone would require the labor of 6 people daily, severely restricting production efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a structure that facilitates the peeling of release paper, solves the problems existing in the prior art, fills the gap in the automated production process of release paper peeling, facilitates the use of machinery to achieve automated peeling of release paper, improves work efficiency, reduces labor costs, and actively promotes industrial automation.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A structure for easy peeling of release paper includes a circuit board product and release paper. The upper surface of the circuit board product is provided with double-sided adhesive. The release paper adheres to the upper surface of the double-sided adhesive and completely covers it. One end of the release paper has a protrusion extending beyond the edge of the circuit board product. A circular hole is provided on the protrusion. The release paper has a dividing portion, including a first cutting line parallel to the long side of the release paper and a second cutting line. The first cutting line is located between the two ends of the release paper. One end of the second cutting line is connected to the first cutting line, and the other end is connected to one long side of the release paper.

[0007] The adhesive strength of the double-sided tape is 20-50 grams.

[0008] The second dividing line is perpendicular to the long side of the release paper.

[0009] Preferably, the distance between the second cutting line and the end of the release paper adjacent to the circular hole is set to 2.2±0.1mm, and the length of the first cutting line is set to 4.5±0.2mm.

[0010] The diameter of the circular hole is 1 mm.

[0011] A third arc-shaped cutting line is provided at the end of the first cutting line away from the second cutting line, and the third cutting line is biased toward the long side of the second cutting line in the same direction.

[0012] After adopting the above technical solution, the present invention has the following technical effects:

[0013] This invention utilizes a protrusion extending beyond the edge of the circuit board product and its circular hole. An automated device's hook can grasp the protrusion of the release paper. The hook moves horizontally a preset distance towards the circuit board product before pulling upwards, automatically peeling off the release paper and achieving automation. This significantly improves production efficiency and reduces labor costs. Furthermore, by incorporating a dividing section with a first and second cutting line, the first dividing line separates the release paper into left and right parts along its length. During the peeling process, one half of the release paper can be pulled first, followed by a 180° rotation to pull the other half. This reduces the pulling force and prevents excessive torque from the automated device from affecting the product. Attached Figure Description

[0019] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0020] refer to Figure 2-3 As shown, this utility model discloses a structure for easy peeling of release paper, including a circuit board product 1 and release paper 2. The upper surface of the circuit board product 1 is provided with double-sided adhesive 3, and the release paper 2 is attached to the upper surface of the double-sided adhesive 3 and completely covers the double-sided adhesive 3.

[0021] One end of the release paper 2 has a protrusion 21 that extends beyond the edge of the circuit board product 1; a round hole 22 is provided on the protrusion 21, which can be used to cooperate with the hook of the automated equipment to hook the protrusion 21 of the release paper 2 so as to automatically peel off the release paper 2.

[0022] The release paper 2 is provided with a dividing part 23, which includes a first cutting line 231 parallel to the long side of the release paper 2 and a second cutting line 232. The first cutting line 231 is located between the two ends of the release paper 2. One end of the second cutting line 232 is connected to the first cutting line 231, and the other end is connected to one of the long sides of the release paper 2.

[0023] Through the above solution, this utility model, using the protrusion 21 extending beyond the edge of the circuit board product 1 and its circular hole 22, can utilize the hook of an automated device to hook the protrusion 21 of the release paper 2. The hook moves horizontally a preset distance towards the circuit board product 1 and then pulls upwards, achieving automatic peeling of the release paper 2, thus achieving automation, greatly improving production efficiency, and reducing labor costs. By providing a dividing section with a first cutting line 231 and a second cutting line 232, the first cutting line 231 divides the release paper 2 into left and right parts along its length. During the process of pulling to peel the release paper 2, one half of the release paper 2 can be pulled first, and then rotated 180° to pull the other half (see reference). Figure 3 (The arrow in the image indicates the direction of the tension), which reduces the pulling force and prevents excessive torque output by automated equipment from affecting the product.

[0024] The following are specific embodiments of the present invention.

[0025] The ideal adhesive strength of the double-sided tape 3 is 20-50 grams. This avoids the release paper 2 and double-sided tape 3 from falling off simultaneously during use due to insufficient adhesive strength, and also avoids the difficulty in separating the release paper 2 and double-sided tape 3 during peeling due to excessive adhesive strength.

[0026] The second dividing line 232 mentioned above is perpendicular to the long side of the release paper 2.

[0027] Furthermore, the distance between the second cutting line 232 and the end of the release paper 2 adjacent to the circular hole 22 is set to 2.2±0.1mm, and the length of the first cutting line 231 is set to 4.5±0.2mm.

[0028] The diameter of the aforementioned circular hole 22 is 1 mm.

[0029] The first cutting line 231 is provided with an arc-shaped third cutting line 233 at the end away from the second cutting line 232. The third cutting line 233 is biased towards the long side of the second cutting line 232 in the same direction.

[0030] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
