Description

Technical Field

[0001] This utility model relates to the field of capacitive touch screen manufacturing technology, and in particular to a capacitive touch screen ribbon cable adhesive application device. Background Technology

[0002] The ribbon cable of a capacitive touchscreen is a key flexible circuit component that connects the touchscreen sensor layer to the controller or other circuit modules. It is responsible for transmitting the coordinate sensing signals (such as X+, X-, Y+, Y-, etc.) of the capacitive touchscreen to the controller. It achieves accurate detection of the touch position through changes in electrical signals and is usually implemented using FPC (flexible printed circuit) technology.

[0003] The bonding of the ribbon cable is a crucial step in the assembly of capacitive touchscreens. It involves applying ACF conductive adhesive to the screen or the ribbon cable, then attaching the cable to the screen, and finally curing it through heat pressing to complete the bonding between the ribbon cable and the screen glass substrate. The adhesive application and heat pressing processes are typically performed using an ACF bonding machine and a ribbon cable pressing machine.

[0004] Currently, the placement and alignment of the ribbon cable onto the screen glass surface requires manual placement and initial pressing assembly. During manual placement, the ribbon cable typically comes into contact with the screen at different points, making vertical placement difficult. This causes horizontal pressure on the ACF conductive adhesive, leading to tilting and twisting of the ACF during placement. After placement, the ACF returns to its original position, causing misalignment between the ribbon cable and the screen glass. Ultimately, this results in poor conductivity after heat pressing, impacting product yield. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a capacitive touch screen ribbon cable adhesive application device to solve the problem that the FPC cannot make perpendicular contact with the screen during the manual placement and application process, resulting in low product yield.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a capacitive touch screen ribbon cable adhesive bonding device, used to bond the ribbon cable to the screen glass, the screen glass having a protrusion, and the ribbon cable having a notch corresponding to the protrusion, comprising:

[0007] The substrate has a plate-like structure with stepped grooves inside. The stepped grooves extend inward from the adjacent two sides of the substrate, and the screen glass is accommodated in the stepped grooves. One side of the stepped groove has an extension groove corresponding to the protrusion. The extension groove extends from the side of the substrate to at least the middle of the substrate.

[0008] The pressing mechanism, mounted above the extension groove via a track, includes a central rod, a fixed plate, a first pressing plate, and a telescopic part. The central rod is slidably connected to the track via the fixed plate. The central rod is positioned corresponding to the protrusion, with its bottom abutting against the protrusion. In the vertical direction, the projection area of ​​the central rod coincides with the protrusion. The first pressing plate is sleeved on the central rod and located below the track. The telescopic part is positioned between the fixed plate and the first pressing plate, allowing the first pressing plate to move towards the fixed plate. An adsorption mechanism is provided on the bottom side of the first pressing plate away from the stepped groove.

[0009] In one embodiment, the center rod includes a fixed part and a sliding part. The fixed part has a sliding groove on its axis, and the sliding part extends into the sliding groove. A positioning spring is provided in the sliding groove, and the two ends of the positioning spring are respectively connected to the fixed part and the sliding part.

[0010] In one embodiment, the bottom of the center rod is provided with a lifting chamfer, which is provided at least on the side of the center rod near the entrance of the stepped groove.

[0011] In one embodiment, the fixing plate has sliding grooves on both sides, the sliding grooves are slidably connected to the track, and the sliding grooves are provided with locking bolts above the sliding grooves.

[0012] In one embodiment, a second pressure plate is provided at the bottom of the side of the first pressure plate away from the stepped groove. The first pressure plate is provided with an adjustment screw hole, and the second pressure plate is screwed to the adjustment screw hole by an adjustment bolt.

[0013] In one embodiment, the track includes a support portion and a sliding portion, the sliding portion being distributed along the length direction of the stepped groove and located above the substrate; one end of the support portion is connected to the side wall of the substrate, and the other end of the support portion is connected to the sliding portion, the support portion being provided at least at the side wall where the stepped groove is not provided.

[0014] In one embodiment, the support portion is connected to the sliding portion via a transition portion.

[0015] In one embodiment, the pressing mechanism further includes a support plate disposed below the first pressure plate, and the support plate is telescopically connected to the side wall of the first pressure plate.

[0016] In one embodiment, a buffer pad is provided at the bottom of the first pressure plate on the side near the stepped groove.

[0017] In one embodiment, the stepped groove is provided with adsorption through holes.

[0018] The beneficial effects of this invention are as follows: In the existing process of attaching ribbon cables to screen glass, alignment and bonding are usually done manually. However, during manual bonding, the ribbon cable, being a flexible structure, is easily deformed when held. Furthermore, when placed, the ribbon cable and screen glass often form an angle, with some areas making preferential contact. This causes the ACF conductive adhesive to stretch and twist. After the hand is released, the elasticity of the ACF conductive adhesive causes the alignment between the ribbon cable and screen glass to shift or become loosely bonded, ultimately affecting the conductivity of the ribbon cable and screen glass after heat sealing and reducing yield. Therefore, the capacitive touchscreen ribbon cable bonding device provided by this invention uses a pressing mechanism to adsorb the ribbon cable and press it vertically downwards, ensuring that the gold fingers of the ribbon cable can simultaneously contact the screen glass or the ACF conductive adhesive, guaranteeing vertical conductivity after heat sealing and thus improving product yield.

[0019] Meanwhile, the presence of the center rod allows for pre-alignment adjustment of the ribbon cable. After adjustment, it can be moved vertically and pressed down, avoiding situations such as inaccurate alignment during manual pasting that lead to tearing and repeated pasting. This effectively prevents gaps and tearing of the ACF adhesive, providing adjustment margin during the bonding process and further ensuring product yield. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Please refer to Figures 1 to 7A capacitive touchscreen ribbon cable bonding device is disclosed, used to bond a ribbon cable 4 to a screen glass 5. The screen glass 5 has a protrusion, the upper surface of which is slightly higher than the upper surface of the screen glass 5. The ribbon cable 4 has a notch corresponding to the protrusion. After the ribbon cable 4 is bonded to the screen glass 5, the upper surface of the gold fingers is flush with the upper surface of the protrusion. Specifically, the screen glass 5 has a protrusion, and the gold fingers of the ribbon cable 4 have notches for foolproof positioning and auxiliary positioning. ACF conductive adhesive is also applied to the gold fingers. After the notches are aligned and bonded to the protrusion, the gold fingers of the ribbon cable 4 are connected to the conductive pattern of the screen glass 5. Those skilled in the art can adjust the specific shape and specifications of the screen glass 5 and the ribbon cable 4 as needed, without specific limitations.

[0033] The capacitive touchscreen cable bonding device includes a substrate 1 and a pressing mechanism 2. The substrate 1 has a plate-like structure and a stepped groove 11 inside. The stepped groove 11 extends inward from the adjacent two sides of the substrate 1, and the screen glass 5 is accommodated in the stepped groove 11. One side of the stepped groove 11 has an extension groove 12 corresponding to a protrusion, and the extension groove 12 extends from the side of the substrate 1 to at least the middle of the substrate 1. That is, the screen glass 5 can enter or leave the stepped groove 11 from the two sides of the substrate 1. The part of the stepped groove 11 extending into the substrate 1 forms a right-angled sidewall to position the screen glass 5, and the extension groove 12 is provided corresponding to the protrusion of the screen glass 5 to avoid and accommodate the protrusion. Preferably, the size of the stepped groove 11 is larger than the size of the screen glass 5, so that the screen glass 5 can be completely accommodated in the stepped groove 11, ensuring the support of the substrate 1 for the screen glass 5. Specifically, the position and size of the stepped groove 11 and the extension groove 12 on the substrate 1 can be adjusted by those skilled in the art as needed, so that the screen glass 5 can slide in and out normally, without any specific limitation.

[0034] The pressing mechanism 2 is mounted above the extension groove 12 via a track 25 and includes a central rod 21, a fixed plate 22, a first pressure plate 23, and a telescopic part 24. The central rod 21 is slidably connected to the track 25 via the fixed plate 22. The central rod 21 is positioned corresponding to the protrusion, with its bottom abutting against the protrusion. In the vertical direction, the projection area of ​​the central rod 21 coincides with the protrusion. The first pressure plate 23 is fitted onto the central rod 21 and is located below the track 25. The telescopic part 24 is positioned between the fixed plate 22 and the first pressure plate 23, allowing the first pressure plate 23 to move towards the fixed plate 22. An adsorption mechanism 3 is provided at the bottom of the first pressure plate 23 on the side away from the stepped groove 11. That is, the fixed plate 22 of the pressing mechanism 2 moves back and forth above the substrate 1 via the track 25, so that the central rod 21 corresponds to the protrusion of the screen glass 5. The first pressure plate 23 slides up and down along the central rod 21 via the telescopic part 24, and the ribbon cable 4 is adsorbed below the first pressure plate 23 via the adsorption mechanism 3. In use, the notch of the ribbon cable 4 is nested with the center rod 21, so that it is guided to the surface of the screen glass 5 and completes the initial pressing when the first pressure plate 23 descends. After pressing, the first pressure plate 23 rises under the action of the telescopic part 24, and the ribbon cable 4 moves out together with the screen glass 5. Specifically, there is a gap between the bottom of the center rod 21 and the extension groove 12 to accommodate the protrusion, and the upper surface of the protrusion abuts against the bottom surface of the center rod 21.

[0035] Specifically, the telescopic part 24 can be in the form of a spring, a spring combined with a telescopic rod, etc., without specific limitations.

[0036] Specifically, the adsorption mechanism 3 can adopt structures such as suction cups and suction holes. The suction cups and suction holes are connected to external vacuum equipment through the first pressure plate 23, without specific limitations. Simultaneously, a control button can be provided on the upper surface of the first pressure plate 23, which can be pressed to control the start or stop of the adsorption mechanism 3. This ensures that the adsorption mechanism 3 remains open while the operator presses down on the first pressure plate 23, and stops adsorption when the operator releases the pressure, while the first pressure plate 23 rises, ensuring that adsorption and bonding operations are performed synchronously during the bonding process, resulting in smooth and convenient operation. Specifically, those skilled in the art can adjust the structure of the adsorption mechanism 3 as needed, without specific limitations.

[0037] In actual operation, the operator places the screen glass 5 along the side wall of the stepped groove 11. After placement, the position of the pressing mechanism 2 is adjusted so that the center rod 21 is aligned with the protrusion of the screen glass 5. Then, the notch of the ribbon cable 4 is aligned with the center rod 21, and the adsorption mechanism 3 is activated to adsorb the ribbon cable 4 under the first pressure plate 23. The ribbon cable 4 is adjusted to fully unfold, and then the adsorption is maintained while the first pressure plate 23 is pressed down, causing the ribbon cable 4 to descend along with the first pressure plate 23. The notch of the ribbon cable 4 is guided to the outside of the protrusion, and the gold fingers of the ribbon cable 4 are bonded to the screen glass 5 through ACF conductive adhesive. The first pressure plate 23 is released, the adsorption mechanism 3 stops adsorption, and the first pressure plate 23 retracts under the action of the telescopic part 24. The ribbon cable 4 overflows along with the screen glass 5, completing the bonding process.

[0038] Preferably, the center rod 21 is a prism. This setting can prevent the first pressure plate 23 from tilting and can keep the first pressure plate 23 horizontal during movement, ensuring that the ribbon cable 4 and the screen glass 5 are vertically attached.

[0039] Because the thickness of the screen glass 5 varies, fixing the distance between the center rod 21 and the extension groove 12 may result in the screen glass 5 not being able to be placed or the center rod 21 not being able to abut against the screen glass 5. Therefore, in this embodiment, the center rod 21 includes a fixing part 211 and a sliding part 212. The fixing part 211 has a sliding groove 213 on its axis, and the sliding part 212 extends into the sliding groove 213. An alignment spring 214 is provided in the sliding groove 213, and the two ends of the alignment spring 214 are respectively connected to the fixing part 211 and the sliding part 212. This allows the capacitive touch screen cable adhesive device to have adjustment margin, enabling it to adapt to screen glass 5 of different thicknesses and ensuring that the center rod 21 and the protrusion can maintain contact. When placing the screen glass 5, the operator lifts the sliding part 212 and then aligns the sliding part 212 with the protrusion.

[0040] Preferably, the sliding part 212 is detachably connected to the alignment spring 214, and the first pressure plate 23 is detachably connected to the telescopic part 24. When the specifications of the screen glass 5 and the ribbon cable 4 are changed, the shape and length of the sliding part 212 can be adjusted to match the first pressure plate 23, thus achieving adaptation. This effectively improves the adaptability of the capacitive touch screen ribbon cable adhesive device and reduces costs.

[0041] Furthermore, to further simplify the alignment operation of the screen glass 5, a lifting chamfer 215 is provided at the bottom of the center rod 21. The lifting chamfer 215 is at least located on the side of the center rod 21 near the entrance of the stepped groove 11. The lifting chamfer 215 is arc-shaped, extending from the side wall of the center rod 21 near the entrance of the stepped groove 11 to the bottom of the center rod 21. After the screen glass 5 contacts the lifting chamfer 215, the sliding part 212 slides upward, automatically completing the alignment and preventing the screen glass 5 from being blocked. Preferably, the lifting chamfer 215 is a quarter-sphere, with the arc surface of the sphere aligned with the entrance direction of the stepped groove 11. This allows the screen glass 5, sliding along the stepped groove 11, to automatically lift the center rod 21, completing the alignment of the center rod 21, simplifying the operation and improving efficiency.

[0042] Preferably, to ensure that the pressing mechanism 2 does not shift after being positioned, the fixed plate 22 is provided with sliding grooves 221 on both sides. The sliding grooves 221 are slidably connected to the track 25, and locking bolts 222 are provided above the sliding grooves 221. This design allows the operator to quickly adjust the position of the pressing mechanism 2 and lock it, making the operation simple and convenient.

[0043] In one embodiment, a second pressure plate 232 is provided at the bottom of the side of the first pressure plate 23 away from the stepped groove 11. The first pressure plate 23 has an adjustment screw hole 231, and the second pressure plate 232 is screwed into the adjustment screw hole 231 by an adjustment bolt 233. That is, the second pressure plate 232 is provided at the part of the first pressure plate 23 that contacts the ribbon cable 4, and the distance between the second pressure plate 232 and the first pressure plate 233 is controlled by the adjustment bolt 233. When the specifications of the ribbon cable 4 change, the operator can adjust the second pressure plate 232 to adapt to different ribbon cables 4, effectively enhancing the adaptability of the capacitive touch screen ribbon cable adhesive applicator, so that the capacitive touch screen ribbon cable adhesive applicator can adapt to ribbon cables 4 and screen glass 5 of different thicknesses.

[0044] In one embodiment, the track 25 includes a support portion 251 and a sliding portion 252. The sliding portion 252 is distributed along the length direction of the stepped groove 11 and is located above the substrate 1. One end of the support portion 251 is connected to the side wall of the substrate 1, and the other end of the support portion 251 is connected to the sliding portion 252. The support portion 251 is provided at least in the side wall where the stepped groove 11 is not provided. That is, the sliding portion 252 is provided along the width direction of the substrate 1, and one end of the sliding portion 252 is connected to the part of the substrate 1 where the stepped groove 11 is not provided through the support portion 251. This arrangement can prevent the track 25 from interfering with the insertion and removal of the screen glass 5 and the ribbon cable 4.

[0045] Furthermore, if the sliding section 252 is only supported on one side, it is prone to tilting at the end. Therefore, a transition section 253 is provided along the length direction of the substrate 1 at the end of the sliding section 252 where the support section 251 is not provided. At the same time, the transition section 253 is connected to the side wall of the substrate 1 through the support section 251, ensuring support while avoiding the screen glass 5 and the ribbon cable 4.

[0046] In one embodiment, the pressing mechanism 2 further includes a support plate 26, which is disposed below the first pressure plate 23 and is telescopically connected to the side wall of the first pressure plate 23. The support plate 26 facilitates the placement, adjustment, and unfolding of the cable 4 by the operator. Simultaneously, after the first pressure plate 23 descends, the support plate 26 rises upon contact with the substrate 1 and presses against the cable 4, creating a clamping effect and further ensuring the alignment and unfolding of the cable 4. Specifically, those skilled in the art can adjust the distance between the support plate 26 and the first pressure plate 23 as needed to ensure that the cable 4 is not subjected to excessive force when pressed down; no specific limitation is made.

[0047] In one embodiment, a buffer pad 27 is provided at the bottom of the first pressure plate 23 on the side near the stepped groove 11.

[0048] In one embodiment, the stepped groove 11 is provided with an adsorption through hole 111. The adsorption through hole 111 is used to adsorb the screen glass 5, ensuring that the screen glass 5 does not shift after positioning. Preferably, the start and stop of the adsorption through hole 111 can be controlled by a control button together with the adsorption mechanism 3, simplifying the operation process.

[0049] Although this document uses terms such as substrate, stepped groove, adsorption through-hole, extension groove, and pressing mechanism frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
