A roller bonding machine for SCA adhesive

Abstract

This utility model discloses a roller bonding machine for SCA adhesive, relating to the technical field of SCA adhesive bonding machines. It includes: a base, a worktable fixedly mounted on the top surface of the base, an electrical distribution box fixedly mounted on the left side wall of the base, a controller fixedly mounted on the front side wall of the worktable, a sliding groove on the top surface of the worktable, a movable plate on the top surface of the base, and two fixed blocks fixedly mounted on the top surface of the movable plate. A detection component is included. When the SCA adhesive, due to its high elasticity and thickness, generates static electricity and tends to curl, the adhesive surface instantly attracts the metal blocks, causing the movable blocks to compress a spring and trigger a microswitch. After the detection triggers, the microswitch directly activates an ion gun. The ion air is blown directionally onto the adhesive surface through a hose and air outlet, neutralizing static electricity. This avoids the interference of ambient light and humidity that traditional photoelectric or electrostatic meter solutions are susceptible to, significantly reducing the curling rate and improving the SCA adhesive bonding yield.

Description

Technical Field

[0001] This utility model relates to the technical field of SCA adhesive bonding machines, specifically a roller bonding machine for SCA adhesive. Background Technology

[0002] SCA adhesive is an optically transparent adhesive, a special bonding film for touch screen panels. It is a new generation of special film for touch screen bonding, with superior light transmittance, clarity, and adhesion. It also has excellent moisture resistance, heat resistance, and weather resistance, as well as excellent shock resistance and explosion resistance, which improves the overall safety of touch screen use. SCA adhesive needs to be bonded to the workpiece, so a bonding machine is required.

[0003] A search revealed prior art publication number CN219446112U, which discloses a roller bonding machine for SCA adhesive. The machine includes a worktable with an operating platform mounted at its front end. A support frame is mounted on the right side of the top of the worktable, and a pre-drilled groove is located in the center of the worktable's interior. A placement plate is located on the left side of the top of the worktable. This roller bonding machine for SCA adhesive comprises a flipping platform, silicone rollers, a first suction nozzle, a first negative pressure seat, and a first vacuum pump. The SCA adhesive to be bonded is placed on the bonding platform. The first vacuum pump is then activated, increasing negative pressure inside the first negative pressure seat. The first suction nozzle adsorbs and positions the SCA adhesive. When the bonding platform is below the flipping platform, the silicone rollers are first raised to the workpiece surface to begin bonding. During bonding, the silicone rollers roll on the adhesive surface, expelling air from the adhesive and preventing air bubbles from remaining. After bonding, all platforms are reset. This design effectively solves the problem of air bubbles easily remaining between the adhesive and the workpiece.

[0004] However, existing technologies cannot mechanically detect the static electricity generated in real time during the bonding process of SCA adhesive due to its high elasticity and large thickness. Nor can they simultaneously activate directional ion wind to eliminate static electricity the moment it is detected. This results in defects such as static curling, edge lifting, and subsequent bonding bubbles and adhesive overflow on the adhesive surface in the starting area, which reduces product yield and requires additional machine stoppage and manual intervention, affecting the overall production line cycle time.

[0005] Therefore, based on the above-mentioned search and combined with existing technologies, a roller bonding machine for SCA adhesive is proposed to solve the above problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution:

A lifting groove is provided on one side of the mounting groove, and an air outlet is slidably installed on the inner wall of the lifting groove. A flexible hose is provided between the air outlet and the ion gun.

[0011] Preferably, the flipping assembly includes: two connecting blocks, which are respectively fixedly installed on the bottom surfaces of two supports.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a detection component is provided.

This causes the moving block to compress the spring and trigger a micro switch. After the detection is triggered, the micro switch directly activates the ion gun. The ion air is blown directionally onto the adhesive surface through the hose and air outlet, neutralizing the static electricity. This avoids the interference of ambient light and humidity that traditional photoelectric or electrometer solutions are susceptible to, significantly reducing the curling rate and improving the bonding yield of SCA adhesive.

[0021] 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.

[0022] In one typical implementation of this application, please refer to Figures 1-4As shown, a roller bonding machine for SCA adhesive includes: a base 1, a worktable 2 fixedly mounted on the top surface of the base 1, an electrical distribution box 3 fixedly mounted on the left side wall of the base 1, a controller 4 fixedly mounted on the front side wall of the worktable 2, a sliding groove 5 opened on the top surface of the worktable 2, a movable plate 6 provided on the top surface of the base 1, two fixed blocks 7 fixedly mounted on the top surface of the movable plate 6, a bonding platform 8 provided between the two fixed blocks 7, an adsorption area 9 provided on the top surface of the bonding platform 8, a silicone roller 10 rotatably connected to the left side wall of the bonding platform 8, and an installation groove 20 opened on the top surface of the bonding platform 8.

[0023] There are two supports 11, both of which are fixedly installed on the top surface of the workbench 2. A flipping platform 12 is provided between the two supports 11 through a flipping assembly.

[0024] The detection component is set on the paste platform 8.

[0025] The detection component includes: a micro switch 21, which is fixedly installed on the side wall of the mounting groove 20. A limit post 22 is fixedly installed on the side wall of the mounting groove 20. A movable block 23 is slidably installed on the outer surface of the limit post 22. A spring 24 is provided between the side wall of the movable block 23 and the side wall of the mounting groove 20. A metal block 25 is fixedly installed on the top surface of the movable block 23.

[0026] The detection assembly also includes an ion gun 26, which is fixedly installed on the bottom surface of the mounting groove 20. A lifting groove 27 is provided on one side of the mounting groove 20. An air outlet 28 is slidably installed on the inner wall of the lifting groove 27. A flexible hose is provided between the air outlet 28 and the ion gun 26.

[0027] Based on the above characteristics, the problem of SCA adhesive having high elasticity, large thickness, and being prone to static electricity curling can be solved. Specifically, when static electricity is generated in the SCA adhesive on the pasting platform 8, the metal block 25 is attracted by static electricity, which drives the moving block 23 to pull the spring 24, causing the spring 24 to deform. At the same time, the spring 24 contacts the micro switch 21, which turns on the ion gun 26. When the ion gun 26 is turned on, the ion air generated by the ion gun 26 enters the air outlet 28 through the hose and is then sprayed out from the air outlet 28 to eliminate the static electricity generated in the SCA adhesive and prevent it from curling.

[0028] The flipping assembly includes: a connecting block 14, two connecting blocks 14 are provided, which are fixedly installed on the bottom surface of two supports 11 respectively. A rotating column 15 is rotatably connected between the two connecting blocks 14. The outer surface of the rotating column 15 is fixedly connected to the bottom surface of the flipping platform 12. A rotary motor 16 is fixedly installed on the bottom surface of one of the supports 11. The output shaft of the rotary motor 16 is connected to the rotating column 15.

[0029] A reciprocating lead screw 17 is rotatably connected to the inner wall of the slide 5, and a slider 18 is connected to the outer surface of the reciprocating lead screw 17. A drive motor 19 is fixedly installed on the right side wall of the worktable 2, and the output shaft of the drive motor 19 is connected to the right side wall of the reciprocating lead screw 17.

[0030] The bottom surface of the movable plate 6 is connected to the top surface of the slider 18, and the top surface of the flipping platform 12 is provided with an adsorption area 13.

[0031] Working principle:

[0032] In use, first place the SCA adhesive to be applied on the adsorption area 9 of the bonding platform 8, and start the vacuum system to firmly adsorb the SCA adhesive by negative pressure; then place the workpiece on the adsorption area 13 of the flipping platform 12, and the rotary motor 16 drives the rotating column 15 to flip the flipping platform 12 to the bonding position. The drive motor 19 drives the moving plate 6 to move back and forth along the slide groove 5 through the reciprocating screw 17 and the slider 18, so that the silicone roller 10 rolls the SCA adhesive with constant pressure, completing the initial bonding and removing air bubbles.

[0033] When the SCA adhesive generates static electricity due to its high elasticity and thickness, and exhibits a tendency to curl, the electrostatic field on the adhesive surface generates an instantaneous attraction force on the metal block 25. The metal block 25 slides along the limiting post 22 towards the adhesive surface with the moving block 23, compressing the spring 24 until the moving block 23 touches the micro switch 21. After the micro switch 21 is triggered, the controller 4 immediately starts the ion air gun 26. The ion air enters the air outlet 28 in the lifting groove 27 through the hose and is blown directionally towards the adhesive surface to neutralize static electricity and prevent curling. After the static electricity is eliminated, the attraction force disappears, the spring 24 resets, the metal block 25 disengages from the micro switch 21, the ion air gun 26 automatically shuts off, and the laminating machine continues to work normally, completing a high-yield bonding of the SCA adhesive and the workpiece.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
