Description

Technical Field

[0001] This utility model relates to the field of capacitive screen manufacturing technology, and in particular to a screen cover bonding device. Background Technology

[0002] In the production process of capacitive touchscreens, the screen cover plate needs to be bonded to the screen substrate with attached ribbon cables to complete the assembly of the cover plate and the screen substrate. Currently, although automated bonding equipment exists in conventional production processes, it is costly, requires highly skilled personnel, and is inconvenient to use. Therefore, the industry mainly uses manual labor with molds to position the cover plate and screen substrate, peel off the protective film, and then manually press and bond them together.

[0003] However, the manual pressing method results in inconsistent pressing pressure, pressing range, and pressing position sequence, which may lead to excessive pressure in some areas or insufficient pressure in others. This can damage the cover plate and screen substrate or cause gaps or air bubbles in some areas, affecting product quality. After bonding, manual verification and inspection are required, resulting in low bonding efficiency. Utility Model Content

[0006] The main body is plate-shaped, with a first, second and third stepped groove that gradually decrease in size along the thickness direction. A material notch that runs through the thickness direction of the main body is opened on one side of the main body along the length direction. The material notch extends from the side of the main body to the third stepped groove.

[0007] The first stepped groove is set to correspond to the cover plate, and the second stepped groove is set to correspond to the screen substrate.

[0008] The push-up assembly is set in the third stepped groove and includes a support plate, adjusting bolts and elastic elements; the support plate extends into the second stepped groove under the action of the elastic elements, and after the cover plate and the screen substrate are placed, the cover plate is higher than the first stepped groove.

[0009] The pressure-applying assembly, located at the top of the main body, includes a pressure-applying component that abuts against the top of the main body; the pressure-applying component has inclined chamfers on both sides, and the height of the pressure-applying component is not lower than the height of the side of the cover plate away from the material notch; the pressure-applying assembly is slidably connected to the wall surface on one side of the main body in the width direction, so that the pressure-applying assembly can slide back and forth along the length direction of the main body.

[0010] In one embodiment, the elastic element includes a first adjusting spring and a second adjusting spring. An adjusting screw hole is provided on the support plate. The first adjusting spring and the second adjusting spring are connected to the bottom of the third stepped groove through the adjusting screw hole. An adjusting bolt is provided on the top of the first adjusting spring and the second adjusting spring, and the adjusting bolt is screwed into the adjusting screw hole. The first adjusting spring is located on the side of the support plate away from the material notch. A receiving groove is provided at the bottom of the third stepped groove. When the support plate abuts against the bottom of the third stepped groove, the first adjusting spring and the second adjusting spring are received in the receiving groove.

[0011] In one embodiment, the receiving groove includes a diffuser portion and a cylindrical portion, the diffuser portion gradually expanding from the cylindrical portion to the bottom of the third stepped groove, and the diameter of the cylindrical portion is not less than the diameter of the first adjusting spring and the second adjusting spring.

[0032] Please refer to Figures 1 to 7 A screen cover bonding device for bonding a screen substrate 4 to a cover plate 5 includes a main body 1, a pushing assembly 2, and a pressing assembly 3. The main body 1 is plate-shaped, with a first stepped groove 11, a second stepped groove 12, and a third stepped groove 13 that gradually decrease in size along its thickness direction. A material notch 14 extending through the thickness direction of the main body 1 is provided on one side along its length direction, extending from the side of the main body 1 to the third stepped groove 13. In other words, the main body 1 is a flat plate structure with three levels of rectangular stepped grooves in its central area, with the areas of the first stepped groove 11, the second stepped groove 12, and the third stepped groove 13 gradually decreasing. Simultaneously, the material notch 14 extends from the edge of the main body 1 to the third stepped groove 13, allowing the first stepped groove 11, the second stepped groove 12, and the third stepped groove 13 to communicate with the outside, enabling operators to remove the screen substrate 4 and the cover plate 5 through the material notch 14.

[0033] The first stepped groove 11 is correspondingly set to the cover plate 5, and the second stepped groove 12 is correspondingly set to the screen substrate 4. That is, when placed, the cover plate 5 is in the first stepped groove 11, and the screen substrate 4 is fitted into the second stepped groove 12. This arrangement can ensure accurate positioning of the cover plate 5 and the screen substrate 4.

[0034] The push-up assembly 2 is installed in the third stepped groove 13 and includes a support plate 21, an adjusting bolt 22, and an elastic element 25. Under the action of the elastic element 25, the support plate 21 extends into the second stepped groove 12. After the cover plate 5 and the screen substrate 4 are placed, the cover plate 5 is higher than the first stepped groove 11. Specifically, the elastic element 25 can be a spring, a telescopic rod, or other structure, without specific limitations.

[0035] The pressure-applying assembly 3 has a pressure-applying member 31, which is integrally disposed on the top of the main body 1 and abuts against the top of the main body 1. The pressure-applying member 31 has inclined chamfers 311 on both sides, and its height is not less than the height of the side of the cover plate 5 furthest from the material notch 14. The pressure-applying assembly 3 is slidably connected to the wall surface on one side of the main body 1 in the width direction, allowing the pressure-applying assembly 3 to slide back and forth along the length direction of the main body 1. Specifically, the inclined chamfers 311 extend from the top of the pressure-applying member 31 towards the bottom. After the inclined chamfers 311 are set, the pressure-applying member 31 can contact the cover plate 5 through the inclined surface of the chamfers 311, causing the cover plate 5 to gradually descend as the inclined chamfer advances until the cover plate 5 is flush with the bottom surface of the pressure-applying member 31. After the bottom surface of the pressure-applying member 31 is flush with the cover plate 5, pushing the pressure-applying assembly 3 can press the cover plate 5 against the screen substrate 4. Specifically, the length of the pressure-applying component 31 is not less than the width of the cover plate 5. The width of the pressure-applying component 31 can be adjusted according to the specifications of the cover plate 5 and the screen substrate 4. Those skilled in the art can adjust the length and width of the pressure-applying component 31 according to actual needs, without making specific limitations.

[0036] It is understood that this utility model accommodates the cover plate 5 and the screen substrate 4 through the first stepped groove 11 and the second stepped groove 12, and sets the push component 2 in the third stepped groove 13 so that the cover plate 5 and the screen substrate 4 are placed slightly beyond the first stepped groove 11. Then, the pressure component 3, which can slide back and forth on the surface of the main body 1, presses and adheres the cover plate 5 and the screen substrate 4. The overall operation is simple, and the adhesion pressure is stable and uniform while ensuring accurate positioning, which can effectively improve the adhesion efficiency and adhesion quality.

[0037] Preferably, the material notch 14 can also be opened on one side of the width direction of the main body 1, as long as it does not affect the sliding of the pressure application component 3, without being specifically limited.

[0038] In one embodiment, the elastic element 25 includes a first adjusting spring 23 and a second adjusting spring 24. A through adjusting screw hole 211 is provided on the support plate 21. The first adjusting spring 23 and the second adjusting spring 24 are connected to the bottom of the third stepped groove 13 through the adjusting screw hole 211. Adjusting bolts 22 are provided at the top of the first adjusting spring 23 and the second adjusting spring 24, and the adjusting bolts 22 are screwed into the adjusting screw hole 211. The first adjusting spring 23 is located on the side of the support plate 21 away from the material notch 14. A receiving groove 131 is provided at the bottom of the third stepped groove 13. When the support plate 21 abuts against the bottom of the third stepped groove 13, the first adjusting spring 23 and the second adjusting spring 24 are accommodated in the receiving groove 131. That is, one end of the first adjusting spring 23 and the second adjusting spring 24 is located in the adjusting screw hole 211 and connected to the adjusting bolt 22, while the other end of the first adjusting spring 23 and the second adjusting spring 24 is fixed in the receiving groove 131. The operator can adjust the relative height between the support plate 21 and the bottom of the third stepped groove 13 by adjusting the adjusting bolt 22, thereby adjusting the elastic force provided by the pushing assembly 2 to the screen substrate 4 and the cover plate 5, improving the overall adjustability of the device. Furthermore, this design, by accommodating the groove 131, prevents the first adjusting spring 23 and the second adjusting spring 24 from entering between the support plate 21 and the third stepped groove 13 when compressed, thus avoiding interference with the lifting and lowering of the support plate 21, ensuring the stability of the pushing and compression, and further ensuring the normal bonding process.

[0039] In one embodiment, the receiving groove 131 includes a diffuser portion 1311 and a cylindrical portion 1312. The diffuser portion 1311 gradually expands and extends from the cylindrical portion 1312 to the bottom of the third stepped groove 13. The diameter of the cylindrical portion 1312 is not less than the diameter of the first adjusting spring 23 and the second adjusting spring 24. That is, the receiving groove 131 is a funnel-shaped groove with a gradually expanding diffuser section 2112 at the top. This arrangement ensures that when the first adjusting spring 23 and the second adjusting spring 24 are subjected to pressure and torsion and tilt laterally, the torsional portion will enter the diffuser portion 1311. This effectively prevents the torsional portion from entering between the support plate 21 and the third stepped groove 13, thereby preventing the torsional portion from preventing the support plate 21 from descending, preventing the support plate 21 from getting stuck and causing excessive pressure on the cover plate 5 by the pressure-applying member 31, and preventing damage to the cover plate 5 and the screen substrate 4.

[0040] In one embodiment, the adjusting screw hole 211 includes a screw section 2111 and a diffuser section 2112. The diffuser section 2112 is disposed at the bottom of the support plate 21, corresponding to the diffuser portion 1311. The screw section 2111 extends from the top of the support plate 21 to the diffuser section 2112, and the screw section 2111 is provided with threads. That is, the diffuser section 2112 and the diffuser portion 1311 together form a diffuser cavity, so that the torsional portions of the first adjusting spring 23 and the second adjusting spring 24 can be accommodated in the diffuser cavity, further ensuring the stable operation of the bonding process.

[0041] In one embodiment, two first adjusting springs 23 and two second adjusting springs 24 are provided. The first adjusting springs 23 and the second adjusting springs 24 are respectively located at the four corners of the support plate 21. This arrangement allows the first adjusting springs 23 and the second adjusting springs 24 to transmit power more evenly to the main body 1, ensuring the stability of the pushing assembly 2.

[0042] In one embodiment, in the thickness direction of the main body 1, the projection area of ​​the support plate 21 is within the projection area of ​​the third stepped groove 13, and the length of the first adjusting spring 23 is less than the length of the second adjusting spring 24; the second stepped groove 12 has an adjusting slope 121 on its side wall near the first adjusting spring 23. Specifically, the side wall of the second stepped groove 12 near the first adjusting spring 23 includes a vertical surface and an adjusting slope 121, and the adjusting slope 121 extends upward at an angle from the top of the vertical surface toward the side away from the screen substrate 4. That is, the size of the support plate 21 is smaller than the size of the third stepped groove 13, and under the action of the first adjusting spring 23 and the second adjusting spring 24, the support plate 21 is in an inclined state, so that the side of the support plate 21 near the first adjusting spring 23 is lower than the side near the second adjusting spring 24. Simultaneously, the adjustment ramp 121 on the second stepped groove 12 causes the screen substrate 4 to tilt slightly after placement. This ensures that the cover plate 5 first contacts the side of the screen substrate 4 closest to the second adjustment spring 24, and then gradually contacts the entire screen substrate 4, further reducing any potential air bubbles between the screen substrate 4 and the cover plate 5 and improving the bonding quality. Those skilled in the art can adjust the lengths of the first adjustment spring 23 and the second adjustment spring 24, as well as the tilt angle of the adjustment ramp 121, according to actual conditions; no specific limitations are imposed.

[0043] In one embodiment, the surface of the pressure-applying component 31 is covered with a buffer layer. The buffer layer effectively prevents the pressure-applying component 31 from scratching the cover plate 5, ensuring a high yield rate.

[0044] In one embodiment, a sponge pad 212 is provided on the top of the support plate 21. After the sponge pad 212 is provided, it can not only buffer the screen substrate 4, but also prevent excessive force between the screen substrate 4 and the support plate 21, which would cause damage to the ribbon cable on the lower side of the screen substrate 4.

[0045] In one embodiment, the pressure-applying assembly 3 further includes an L-shaped pressure plate 32 and a slider 33. The slider 33 is at least disposed on the side of the L-shaped pressure plate 32 near the main body 1. A groove 15 is provided on the wall surface of the main body 1 in the width direction and / or on the top of the main body 1, and the slider 33 is disposed in the groove 15. The pressure-applying element 31 is disposed on the side of the L-shaped pressure plate 32 near the top of the main body 1. That is, the pressure-applying assembly 3 is L-shaped in general. The short side of the L-shaped pressure plate 32 is connected to the groove 15 on the wall surface of the main body 1 in the width direction through the slider 33, and the long side of the L-shaped pressure plate 32 is provided with the pressure-applying element 31. The long side of the L-shaped pressure plate 32 can also be connected to the groove 15 on the top of the main body 1 through a T-shaped slider 33. Specifically, the slider 33 can be in the form of T-shape, sphere, etc., and the groove 15 is adjusted according to the form of the slider 33, without specific limitation. This arrangement allows the L-shaped pressure plate 32 to remain in contact with the main body 1 during sliding, thereby ensuring that the pressure-applying element 31 can stably apply pressure to the cover plate 5 and the screen substrate 4.

[0046] Preferably, the pressure-applying component 31 is detachably connected to the L-shaped pressure plate 32. This arrangement allows the operator to replace the pressure-applying component 31 as needed, thereby adjusting its width and length and improving the adaptability of the device.

[0047] In one embodiment, the L-shaped pressure plate 32 has a top gripper 34. Specifically, the gripper 34 is located on the side of the L-shaped pressure plate 32 where the long side is away from the short side, and the gripper 34 can be a cylindrical handle or a hollow handle. This arrangement allows the operator to push and pull the pressure application component 3 with one hand, improving the bonding efficiency.

[0048] Preferably, two grooves 15 are arranged parallel to each other on one side of the wall of the main body 1 in the width direction. This arrangement limits the relative angle between the L-shaped pressure plate 32 and the main body 1, further preventing the L-shaped pressure plate 32 from shifting or tilting, and ensuring the stability of the pressure application process.

[0049] Please refer to Figure 1 to... Figure 7 Embodiment 1 of this utility model is: a screen cover plate bonding device for bonding a screen substrate 4 and a cover plate 5, comprising:

The first adjusting spring 23 is located on the side of the support plate 21 away from the material notch 14. The bottom of the third stepped groove 13 has a receiving groove 131. When the support plate 21 abuts against the bottom of the third stepped groove 13, the first adjusting spring 23 and the second adjusting spring 24 are received in the receiving groove 131. The support plate 21 extends into the second stepped groove 12 under the action of the first adjusting spring 23 and the second adjusting spring 24. After the cover plate 5 and the screen substrate 4 are placed, the cover plate 5 is higher than the first stepped groove 11.

[0053] The pressure application component 3 is located on the top of the main body 1 and includes a pressure application member 31, which abuts against the top of the main body 1. The pressure application member 31 has inclined chamfers 311 on both sides, and the height of the pressure application member 31 is not lower than the height of the cover plate 5 near the first adjusting spring 23. The pressure application component 3 is slidably connected to the wall surface on one side of the width direction of the main body 1, so that the pressure application component 3 can slide back and forth along the length direction of the main body 1.

[0054] The receiving groove 131 includes a diffuser 1311 and a cylindrical portion 1312. The diffuser 1311 gradually expands and extends from the cylindrical portion 1312 to the bottom of the third stepped groove 13. The diameter of the cylindrical portion 1312 is not less than the diameter of the first adjusting spring 23 and the second adjusting spring 24.

[0055] The adjusting screw hole 211 includes a screw section 2111 and a diffuser section 2112.

The screw section 2111 extends from the top of the support plate 21 to the diffuser section 2112. The screw section 2111 is provided with threads.

[0056] In the thickness direction of the main body 1, the projection area of ​​the support plate 21 is within the projection area of ​​the third stepped groove 13, and the length of the first adjusting spring 23 is less than the length of the second adjusting spring 24; the second stepped groove 12 is provided with an adjusting slope 121 on the side wall near the first adjusting spring 23.

[0057] The pressure application component 3 also includes an L-shaped pressure plate 32 and a T-shaped slider 33. The T-shaped slider 33 is at least provided on the side of the L-shaped pressure plate 32 near the main body 1.

The pressure application component 31 is provided on the side of the L-shaped pressure plate 32 near the top of the main body 1.

[0058] In this embodiment, the top gripper 34 of the L-shaped pressure plate 32 and the slide groove 15 are arranged in parallel on one side of the wall surface of the main body 1 in the width direction.

[0059] The working principle of this utility model is as follows: Before use, the operator adjusts the adjusting bolt 22 as needed to control the position and angle of the support plate 21. Then, the operator places the screen substrate 4 into the second stepped groove 12, and positions the screen substrate 4 through the three side walls of the second stepped groove 12 without the adjusting slope 121. The support plate 21 supports the screen substrate 4, and the screen substrate 4 is tilted under the support of the support plate 21 and the adjusting slope 121. Then, the operator peels off the adhesive film on the upper surface of the screen substrate 4, and at the same time peels off the adhesive film at the bottom of the cover plate 5, and places the cover plate 5 into the first stepped groove 11. The cover plate 5 contacts the screen substrate 4 and lowers the screen substrate 4 and the support plate 21 as a whole, with the cover plate 5 slightly higher than the first stepped groove 11. After placement, the operator pulls the grip 34 to make the pressure applying member 31 move back and forth along the surface of the main body 1 once. After pressure is applied, the operator takes out the attached cover plate 5 and screen substrate 4 through the material notch 14, and the attachment is completed.
