Description

Technical Field

[0001] The present invention relates to the technical field of circuit board gluing equipment, and in particular to a flexible circuit board reinforcement gluing device. Background Art

[0002] Flexible printed circuit boards (FPCs) are highly reliable and flexible printed circuit boards made from polyimide or polyester film. They feature high wiring density, light weight, thin thickness, and excellent bendability.

[0003] Flexible circuit boards, because of their soft substrate, can be bent and folded to accommodate various spatial requirements. However, this flexibility also translates to relatively low mechanical strength. In certain applications, particularly those requiring frequent bending or subject to external impact, the flexibility of flexible circuit boards may not be sufficient to meet the stability and durability requirements. In these cases, the flexible circuit board needs reinforcement. This reinforcement process typically involves adding one or more layers of material to the flexible circuit board's substrate to increase its overall strength and rigidity. This reinforcement not only increases the flexible circuit board's resistance to bending but also helps prevent tearing or breaking during use.

[0004] When reinforcing a flexible circuit board, it is necessary to stick reinforcing material on the surface of the flexible circuit board. During this process, the reinforcing material layer needs to be stuck on the flexible circuit board through a layer of glue. In the existing technology, manual gluing and reinforcement of the flexible circuit board is adopted, which is inefficient and easily causes damage to the flexible circuit board. In addition, the range of gluing is difficult to control. When using the flexible circuit board, it is not necessary to glue and reinforce all areas.

The second pillar 45 has a plate-shaped structure, and the first drive motor 9 is fixed to the inner side of the top of the second pillar 45 through a bracket, and the output shaft of the first drive motor 9 is connected to the second rotating shaft 46, and the second rotating shaft 46 is sleeved on the second bearing 47 , and passes through the outer side of the second pillar 45 and is connected to the second reel 8. In order to facilitate the collection of the release film 50 waste of the adhesive tape 11, two third circular baffles 48 are provided at intervals on the second reel 8. The two third circular baffles 48 form a gap. During installation, the two third circular baffles 48 are first inserted into the second reel 8, and then a third limiting ring 49 is inserted to block the third circular baffle 48 located on the outer side. The third limiting ring 49 can be detachably mounted on the second reel 8 by screws, which is convenient for disassembly and installation. Finally, during operation, the end of the release film 50 of the adhesive tape 11 is pasted on the gap formed by the two third circular baffles 48, and the first drive motor 9 is started to drive the second reel 8 to rotate. The release film 50 of the adhesive tape 11 is wound on the above-mentioned gap to realize the collection of the release film 50 waste of the adhesive tape 11.

[0040] The tape mounting frame 3 is provided with a freely rotatable third reel 10, and the tape 11 is wound on the third reel 10. Specifically, the tape mounting frame 3 includes a third pillar 51 and a third reel 10. The third reel 10 is rotatably connected to the top of the third pillar 51, and the tape 11 is wound on the third reel 10. The wound tape 11 rotates with the rotation of the third reel 10. In this embodiment, the third pillar 51 is a plate-shaped structure, and the bottom of the third pillar 51 is fixed to the surface of the mounting plate 5 by screws. A third bearing 52 is fixed to the inner side of the third pillar 51, and the third rotating shaft 53 passes through the third bearing 52 and passes through the outer side of the top of the third pillar 51.

It can be understood that the first limiting ring 58 is detachably mounted on the third reel 10 by screws. In addition to limiting the outer first circular baffle 57, it is also convenient for disassembly and installation. During operation, the reinforcing coil 7 and the tape 11 are pulled under the drive of the second drive motor 13 of the material receiving rack 4, thereby pulling the third reel 10 to rotate, so that the tape 11 rotates accordingly, providing the reinforcing coil 7 with the tape 11 for pasting.

[0041] The material receiving rack 4 is provided with a fourth reel 12 and a second drive motor 13, and the fourth reel 12 is driven to rotate by the second drive motor 13; specifically, the material receiving rack 4 includes a fourth pillar 59 and a fourth reel 12, the fourth pillar 59 is a plate-shaped structure, the bottom of the fourth pillar 59 is fixed to the surface of the mounting plate 5 by screws, the rear side of the top of the fourth pillar 59 is fixed with the second drive motor 13 and the second bearing 47 by a bracket, the output shaft of the second drive motor 13 is connected to the fourth rotating shaft 61, and the fourth rotating shaft 61 is sleeved on the second bearing 47 and passes through the fourth pillar 59, and is connected to the fourth reel 12 on the fourth rotating shaft 61. A fourth circular baffle 63 is fixed on the reel 12, and a detachable fourth limiting ring 62 is provided at a certain distance from the fourth reel 12. The fourth limiting ring 62 can be detachably mounted on the fourth reel 12 by screws. During operation, the second drive motor 13 is started to drive the fourth reel 12 to rotate, and the glue reinforcement plate 23 after gluing is completed is clamped in the gap formed by the fourth limiting ring 62 and the fourth circular baffle 63. As the fourth reel 12 rotates, the glue reinforcement plate 23 is wound up. During this process, the fourth circular baffle 63 and the fourth limiting ring 62 have a shielding effect on the wound glue reinforcement plate 23, preventing the glue reinforcement plate 23 from being offset during the winding process.

[0042] In addition, the guide assembly includes a reinforcement guide frame 14, a tape guide frame 15, a bonding guide frame 16 and a glue reinforcement guide frame 17; the reinforcement guide frame 14 is arranged between the reinforcement coil mounting frame 1 and the tape mounting frame 3, the tape guide frame 15 is arranged on the tape mounting frame 3, the bonding guide frame 16 is arranged between the reinforcement guide frame 14 and the glue reinforcement guide frame 17, and the glue reinforcement guide frame 17 is located between the tape mounting frame 3 and the material receiving frame 4; the bonding guide frame 16 and the glue reinforcement guide frame 17 are both provided with positioning grooves corresponding to the reinforcement coil 7, wherein the positioning grooves are formed by the following first positioning groove 66 and the second positioning groove 27 cooperating with each other, and the tape 11 described in this embodiment is a double-sided tape;

[0043] It is also noted that the tape guide frame 15 includes a guide roller fixed on the third pillar 51, which plays a guiding role in the process of gluing the reinforcement coil 7, thereby facilitating the adhesion of the tape 11 to the reinforcement coil 7.

[0044] During operation, the reinforcing coil 7 passes through the reinforcing guide frame 14, and the reinforcing coil 7 and the tape 11 are converged and pasted at the bonding guide frame 16 to form a glue-on reinforcing plate 23. The glue-on reinforcing plate 23 passes through the bonding guide frame 16 and enters the glue-on reinforcing plate 23 guide frame 1714 and enters the fourth reel 12. The fourth reel 12 rotates under the drive of the second drive motor 13; the release film 50 of the tape 11 is connected to the second reel 8, and the second reel 8 rotates under the action of the first drive motor 9 to collect waste of the release film 50.

[0045] As a preferred embodiment, the reinforcement guide frame 14 includes a concave first fixed frame 18, the bottom of the first fixed frame 18 is fixed on the mounting plate 5, and three first rollers 19 are arranged horizontally side by side and spaced from each other at the opening at the top of the first fixed frame 18. The inner side of the first fixed frame 18 forms a first positioning groove 66 with the first baffle 20, and the first baffle 20 can be detachably installed at the bottom of the first fixed frame 18.

[0046] It can be understood that the concave first fixed frame 18 includes a bottom plate and side plates on both sides, and three fixed shafts are fixed between the two side plates. The three fixed shafts are in the same plane and parallel to the mounting plate 5, and are arranged at equal intervals. Each fixed shaft is sleeved with a first roller 19, and the first roller 19 can rotate freely on the fixed shaft. The first baffle 20 is fixed to the bottom plate by screws. The first baffle 20 is provided with a circular through-hole for the first roller 19 to pass through. When the reinforcement guide frame 14 is working, the reinforcement coil 7 passes through the bottom of the first first roller 19, and then passes through the top of the second first roller 19 from the bottom of the first first roller 19, and finally passes through the top of the second first roller 19 and the bottom of the third first roller 19. Such staggered interlacing helps to spread and tighten the reinforcement coil 7. At the same time, the first positioning groove 66 also limits the two sides of the reinforcement coil 7 to prevent the reinforcement coil 7 from offsetting during the pulling process, resulting in inaccurate position of the subsequent glue application.

[0047] As a preferred embodiment, the fitting guide frame 16 includes a concave second fixed frame 21, the bottom of the second fixed frame 21 is fixed to the mounting plate 5, a pair of mutually cooperating pressure wheel groups 22 are provided at the opening of the second fixed frame 21, and the second baffle 26 can be removably installed at the bottom of the second fixed frame 21.

[0048] It can be understood that the second fixed frame 21 is similar to the first fixed frame 18, and includes a base plate and two side plates. The base plate is fixed on the mounting plate 5, and a freely rolling pressure wheel group 22 is arranged between the two side plates, wherein the pressure wheel group 22 includes two pressure wheels arranged side by side in the vertical direction. During operation, the glue reinforcement plate 23 after the bonding is completed passes through the two clamps to compact the glue reinforcement plate 23, so that the bonding effect between the tape 11 and the reinforcement coil 7 is better.

[0049] As a preferred embodiment, the glue reinforcement guide frame 17 includes a concave third fixed frame 24, the bottom of the third fixed frame 24 is fixed on the mounting plate 5, and three second rollers 25 are horizontally arranged side by side and spaced from each other are provided at the opening of the third fixed frame 24. The inner side of the third fixed frame 24 forms a second positioning groove 27 with the second baffle 26, and the second baffle 26 is detachably installed on the bottom of the third fixed frame 24.

[0050] It can be understood that the third fixed frame 24 has an external structure similar to that of the first fixed frame 18 and the second fixed frame 21, and is composed of a bottom plate and two side plates. The bottom plate is fixed to the mounting plate 5, and three second rollers 25 that can rotate freely are fixed between the two side plates. The three second rollers 25 are arranged at equal intervals and are parallel to the mounting plate 5; and the second baffle 26 is fixed to the bottom plate by screws, and three circular through-holes for the third roller to pass through are respectively provided on the second baffle, and the second baffle 26 and the inner side plate form a second positioning groove 27; during operation, the circuit board glue reinforcement plate 23 after the glue is completed passes through the three second rollers 25 in an interlaced manner, and its glue reinforcement The interlacing method of the reinforcement plate 23 and the type of the reinforcement guide frame 14 are not described in detail. During operation, the glued reinforcement plate 23 can be better fitted on the second roller 25 under the action of the three second rollers 25, which is helpful for the winding of the glued reinforcement plate 23 and keeps the glued reinforcement plate 23 in a tensioned state during this process, preventing the glued reinforcement plate 23 from escaping from the second roller 25, which is not conducive to the transmission of the glued reinforcement plate 23. At the same time, the second positioning groove 27 limits the two sides of the glued reinforcement plate 23, preventing the glued reinforcement plate 23 from deviating during the transmission process, which is not conducive to the winding of the glued reinforcement plate 23.

[0051] As a preferred embodiment, the second fixed frame 21 is provided with a vertically arranged upper guide rod 28 and a lower guide rod 29 at the opening of the second fixed frame 21 on the side close to the reinforcement guide frame 14, and the upper guide rod 28 and the lower guide rod 29 are both provided with a limit block 30 with an adjustable position.

[0052] The limit block 30 is sleeved on the upper guide rod 28 and the lower guide rod 29. It can be understood that the above-mentioned limit block 30 is sleeved on the upper guide rod 28 and the lower guide rod 29. It can be achieved by opening a threaded hole in the limit block 30 and setting a bolt on the threaded hole. By turning the bolt, the limit block 30 can be pressed against the screw. During operation, the upper guide rod 28 mainly guides the adhesive tape 11. First, unscrew the bolt and adjust the limit block 30 to form a distance the same as the width of the adhesive tape 11 on the inner side plate of the fixed frame. Tighten the bolt to fix the limit block 30 on the upper guide rod 28. The limit block 30 and the inner plate form a guide gap the same as the width of the adhesive tape 11, which has a good adhesion effect on the adhesive tape 11 and helps to improve the accuracy of the adhesive tape 7. At the same time, it helps to transport the adhesive tape 11; similarly, the limit block 30 on the lower guide rod 29 can also be adjusted to form a guide gap corresponding to the reinforcement coil 7 on the inner side, which helps to transport and glue the reinforcement coil 7.

[0053] As a preferred embodiment, vertical adjustment holes 33 are provided at both ends of the rotating shaft of the upper pressing wheel of the pressing wheel group 22 corresponding to the second fixed frame 21. The rotating shaft of the upper pressing wheel passes through the vertical adjustment hole 33 and is connected to an adjustment handle 31. The end of the adjustment handle 31 is connected to the rotating shaft through a cam 32.

[0054] It can be understood that vertical adjustment holes 33 are provided on the side panels on both sides of the second fixed frame 21 for adjusting the position of the upper pressure wheel, and the cam 32 is a cam 32 with a straight cross-section at the bottom and an arc-shaped structure on both sides. When the handle is turned, under the action of the arc-shaped structures on both sides of the cam 32, a fixed plate 35 is set below the cam, and the upper pressure wheel moves toward the top of the vertical adjustment hole 33, so that the upper pressure wheel and the lower pressure wheel are pulled apart to form a relatively large gap, which is convenient for passing the ends of the tape 11 and the reinforcing coil 7 after bonding through between the pressure wheel group 22, making it easy to operate.

[0055] It is also noted that above the two vertical adjustment holes 33, adjustment bolts 34 corresponding to the vertical adjustment holes 33 are provided through the two side panels. When the glue-applying reinforcement plate 23 passes through the clamping wheel assembly 22 after the glue-applying is completed, the adjustment bolts 34 on both sides will tighten the fixed axis of the upper clamping wheel to prevent the upper clamping wheel from moving.

[0056] As a preferred embodiment, both the first drive motor 9 and the second drive motor 13 are connected to a speed regulating switch 36 .

[0057] It can be understood that the motor drive speed control switch 36 adopts the existing technology of the number switch, which will not be elaborated here. During operation, the speed of the first drive motor 9 or the second drive motor 13 is adjusted separately through the speed control quick switch, so that the first drive motor 9 and the second drive motor 13 cooperate with each other to complete the collection of the glue reinforcement plate 23 and the collection of the waste of the tape 11 release film 50.

[0058] It should also be noted that an auxiliary guide roller 64 is provided in front of the material receiving rack 4 and behind the reinforcement coil mounting rack 1 to assist in the transmission of the glued reinforcement plate 23 and the reinforcement coil 7; a blower 65 is provided between the bonding guide rack 16 and the glued reinforcement plate 23 guide rack 1714, and the blower 65 is aligned with the glued reinforcement plate 23 to assist in bonding the adhesive tape 11 to the reinforcement coil 7; the above-mentioned first positioning groove and the second positioning groove 27 constitute the above-mentioned positioning groove.

[0059] In summary, the working principle of the present invention is:

[0060] When gluing the reinforcing coil 7, first pull out the reinforcing coil 7 on the reinforcing coil mounting frame 1, pass it through the auxiliary guide roller 64, pull it into the three first rollers 19 inside the reinforcing guide frame 14, and cross-fit it on the three first rollers 19, then stretch it to the fitting guide frame 16, and then pull out the rolled tape 11 on the tape mounting frame 3, peel off the release film 50 on one side of the tape 11, and fit the peeled release film 50 on the second reel 8 of the waste collection frame 2, and stick the end of the peeled tape 11 on the reinforcing coil 7. The sticking position is determined by yourself, and then the upper pressure of the pressure roller wheel group is adjusted by adjusting the handle 31. The roller is lifted upward, and the glued reinforcement plate 23 after bonding is placed into the gap of the pressure wheel group 22, and the glued reinforcement plate 23 is pulled out and crosses through the three second rollers 25 on the bonding guide frame 16, and then passes through the last auxiliary guide roller 64, and its end is pasted on the fourth reel 12. At this time, the first drive motor 9 and the second drive motor 13 are started at the same time. Under the driving action of the second drive motor 13, the glued reinforcement plate 23 is wound on the fourth reel 12, and the tape 11 and the reinforcement coil 7 are pulled for transmission at the same time. Under the action of the first drive motor 9, the second reel 8 completes the release film 50 on the tape 11 and collects the waste.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
