Technical Field
[0001] This utility model relates to the field of flexible circuit board manufacturing technology, and in particular to a double-sided adhesive paper attaching tool. Background Technology
[0002] The underfill adhesive for flexible printed circuit boards (FPCBs) plays a crucial role in their manufacturing and application. It not only strengthens the structural integrity of the FPCB and improves its conductivity, but also protects the circuitry from damage, provides insulation, and ensures environmental sealing.
[0003] In the existing technology, both sides of the flexible circuit board need to be coated with adhesive, and the adhesive application area is usually positioned by a plate-shaped fixture with adhesive positioning holes to improve the accuracy of adhesive application. However, since the adhesive application positions are different on the two sides of the board, different fixtures need to be changed to apply adhesive to both sides of the circuit board. The process of changing fixtures is quite cumbersome, which will undoubtedly greatly reduce the efficiency of adhesive application and have a certain impact on the production of circuit boards.

An adhesive applicator 26 is provided inside the rectangular frame 21.
[0030] Limiting mechanisms 6 are provided at the ends of the two rectangular frames 21 away from the connecting plate 1.
[0031] In this embodiment, during use, the interiors of the two rectangular frames 21 are respectively inserted into the adhesive application fixtures 26 corresponding to the adhesive application areas on both sides of the circuit board. The circuit board is then inserted between the two rectangular frames 21, and the two rectangular frames 21 are merged to clamp the circuit board. Thus, when applying adhesive, both sides of the circuit board can be applied simultaneously, thereby effectively achieving simultaneous adhesive application and improving adhesive application efficiency.
[0032] The positioning groove 23 is used to install the limiting pressure plate 24, and the limiting pressure plate 24 and the limiting frame 22 make it easy to insert the adhesive applicator 26 into the interior of the rectangular frame 21, so as to facilitate the replacement of the adhesive applicator 26.
[0033] Meanwhile, the mounting shaft 5 is used to mount two rectangular frames 21, and the positioning slider 4 allows the distance between the two rectangular frames 21 to be changed, ensuring that the two rectangular frames 21 are always parallel, so that the device can be used for circuit boards of different thicknesses.
[0034] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the positioning slider 4 is square in shape, and the two side walls of the positioning slider 4 are in contact with and slidably connected to the inner wall of the sliding cavity 3.
[0035] In this embodiment, the positioning slider 4 with a square shape, in conjunction with the sliding cavity 3, can effectively improve the stability of the positioning port when it slides inside the sliding cavity 3.
[0036] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, a rotating sleeve 7 is provided at the top of the connecting plate 1, and the inner cavity of the rotating sleeve 7 is connected to the sliding cavity 3. An adjusting screw 8 is rotatably connected inside the rotating sleeve 7, and a threaded hole 9 that cooperates with the adjusting screw 8 is opened inside the positioning slider 4.

Then, the positioning plate 261 is placed inside the rectangular frame 21, and the limiting groove 263 corresponds to the limiting frame 22. After releasing the clamping plates 244, the clamping plates 244 are inserted into the clamping groove 262 under the action of the supporting spring 245, thereby achieving the purpose of fixing the adhesive applicator 26 and facilitating the replacement of the adhesive applicator 26.
