Description

Technical Field

[0001] This utility model relates to the field of display manufacturing technology, specifically to a double-sided adhesive application device. Background Technology

[0002] In modern consumer electronics products, displays use a lot of high-adhesion, precision double-sided adhesive to bond components such as the mid-frame, battery, screen, and back cover in order to achieve a thinner, lighter, and more aesthetically pleasing integrated design.

[0003] Current technology typically involves manual application of double-sided tape according to the product's design drawings. During this process, workers come into contact with the adhesive parts of the tape, which can cause stretching and deformation, rendering the tape unusable. Furthermore, because it is a manual application method, the spacing between the double-sided tapes and between the tape and the product can vary, affecting the product's appearance. In severe cases, the spacing between the double-sided tapes may exceed the design requirements. After the product is assembled onto the machine, the misaligned gaps can lead to reliability issues such as dust and water entering the machine. Utility Model Content

[0016] 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.

[0017] In modern consumer electronics products, displays use a large amount of high-adhesion, precision double-sided tape to bond components such as the mid-frame, battery, screen, and back cover in order to achieve a thinner and more aesthetically pleasing integrated design. Current technology generally involves manual application according to the product's design drawings. During this process, workers come into contact with the sticky parts of the double-sided tape, which can cause stretching and deformation of the easily deformable tape, resulting in the double-sided tape material becoming unusable.

[0018] like Figures 1-5 As shown, this utility model provides a technical solution: a double-sided adhesive applicator, including a fixture 1 and a double-sided adhesive attachment 6. The fixture 1 is made of bakelite with a thickness of 15mm-18mm, preferably 16mm. Limiting blocks 2 are fixed on all four sides of the top of the fixture 1. A rectangular placement cavity is formed between the inner sides of the limiting blocks 2. The workpiece body 5 is placed in the placement cavity, and the four sides of the workpiece body 5 are in contact with the inner sides of the limiting blocks 2. A positioning post 3 made of solid stainless steel is fixed at each of the four corners of the top of the fixture 1.

[0019] To facilitate the handling of workpieces, grooves 101 are provided in the middle of both sides of the fixture table 1. At least two symmetrical limiting blocks 2 are provided on both sides of the grooves 101, and the width of the limiting blocks 2 is less than the depth of the grooves 101.

[0020] like Figure 3 and Figure 4 As shown, the double-sided adhesive attachment 6 includes a double-sided adhesive body 601. It is known that both the top and bottom surfaces of the double-sided adhesive body 601 are coated with adhesive. A transverse release film 602 is adhered to the top of the double-sided adhesive body 601. In this design, the transverse release film 602 is a silicone oil release film, and a positioning film 603 is adhered to the top of the transverse release film 602. To facilitate observation of the position of the double-sided adhesive body 601 during application, one side of the positioning film 603 extends beyond the double-sided adhesive body 601, and the other side is connected to... The double-sided adhesive body 601 is flush with or has a certain distance difference. The positioning film 603 is made of transparent PET material with a thickness of 0.05mm-0.1mm to ensure good flexibility and light transmittance. Positioning holes 604 that are adapted to the positioning posts 3 are symmetrically opened on both sides of the positioning film 603. The diameter of the positioning hole 604 is 0.1mm-0.2mm larger than the diameter of the positioning post 3 so that the positioning film 603 can be smoothly fitted onto the positioning post 3 within the installation accuracy range.

[0021] In addition, to facilitate the peeling operation of the transverse release film 602, an extended release film 605 is formed on both sides of the transverse release film 602. The extended release film 605 is bonded to the positioning film 603, and the length of the extended release film 605 extends at least 5mm beyond the edge of the positioning film 603. When it is necessary to peel off the transverse release film 602, the operator can achieve peeling by pinching the extended release film 605 and pulling it upward.

[0022] like Figure 2 As shown, the workpiece body 5 includes a base plate 501 and a protrusion 502 disposed on the top of the base plate 501. A U-shaped attachment surface 503 is formed between the base plate 501 and the protrusion 502. The double-sided adhesive body 601 on one side is adapted to the attachment surface 503 on the corresponding side. In order to facilitate the smooth placement of the workpiece body 5 into the placement cavity and to facilitate the smooth application of the double-sided adhesive body 601 to the position to be applied, the attachment surface 503 is 0.2mm-0.3mm higher than the top surface of the limiting block 2, preferably 0.2mm higher.

[0023] Working principle: Place the workpiece body 5 in the placement cavity of the fixture table 1, with the attachment surface 503 of the workpiece body 5 facing upwards. Hold the positioning film 603 of the double-sided adhesive attachment 6 with both hands, confirm the attachment position and direction of the double-sided adhesive body 601 according to the product design drawings, align it with the positioning post 3 of the fixture table 1 through the positioning hole 604 on the positioning film 603, and then operate downwards with both hands simultaneously to attach the double-sided adhesive body 601 to the attachment surface 503 of the workpiece body 5. At the same time, press the double-sided adhesive body 601 to ensure full contact with the attachment surface 503. Peel off the positioning film 603 on the double-sided adhesive body 601, leaving the transverse release film 602 on the double-sided adhesive body 601. Attach all the back adhesives according to the drawings in sequence. Finally, remove the product from the placement cavity of the fixture table 1 to obtain the product as shown in the figure. Figure 6 The product shown.
