Description

Technical Field

[0001] This invention relates to the field of mobile phone panel production equipment technology, specifically to a secondary bonding equipment for flexible transparent materials. Background Technology

[0002] In existing technology, the working steps of the bonding equipment for mobile phone panels and heat dissipation film (copper foil) are as follows:

[0003] like Figure 22 As shown, the X-axis module 1' drives the rolling unit 2' to move. The rolling unit 2' moves to directly above the copper foil. The rolling unit 2' moves downward under the drive of the Z-axis module 3'. After the bottom suction cup 4' of the rolling unit 2' adsorbs the copper foil, it moves upward. The X-axis module 1' drives the rolling unit 2' to directly above the phone panel. Then, the rolling unit 2' moves to a position close to the phone panel under the drive of the Z-axis module 3'. The long strip pressure roller 5' on the rolling unit 2' is extended by the cylinder 6'. The length of the long strip pressure roller 5' matches the long side of the phone panel. The long strip pressure roller 5' is located on the back of the copper foil. During the extension of the long strip pressure roller 5', one end of the copper foil is pressed tightly against the long side of the phone panel. Then, under the drive of the Y-axis module 7', the rolling unit moves along the Y-axis direction (short side direction), thereby realizing unidirectional rolling and attaching the copper foil to the phone panel.

[0004] Although the copper foil can be adhered to the mobile phone panel during the above-mentioned copper foil application process, the following problems still exist:

[0005] Existing bonding equipment uses unidirectional rolling to bond copper foil to the mobile phone panel. During this unidirectional rolling process, the pressure applied to the corner areas of the mobile phone panel is often insufficient, resulting in inadequate bonding in the corner areas, a high rate of residual bubbles, and a decrease in the yield rate of the mobile phone panel. Summary of the Invention

[0006] The purpose of this invention is to provide a secondary bonding device for flexible transparent materials to solve at least one of the aforementioned problems in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A secondary bonding device for flexible transparent materials includes an X-axis module, a Y-axis module, and two side-by-side long-side rolling units and two short-side rolling units arranged side by side. The X-axis module is located above the long-side rolling units, and the two Y-axis modules are respectively located above the two short-side rolling units.

[0009] Both the long-side rolling unit and the short-side rolling unit include a pressure application component. The pressure application component of the long-side rolling unit is disposed on the X-axis module, and the pressure application component of the short-side rolling unit is disposed on the Y-axis module. The power output end of the pressure application component is provided with a rolling module.

[0010] The long-side rolling unit and the short-side rolling unit respectively include a first vacuum adsorption mold platform and a second vacuum adsorption mold platform. The first vacuum adsorption mold platform and the second vacuum adsorption mold platform are used to adsorb and position the mobile phone panel with copper foil attached. The rolling module above the first vacuum adsorption mold platform extends along the long side of the mobile phone panel, and the rolling module above the second vacuum adsorption mold platform extends along the short side of the mobile phone panel.

[0011] In this technical solution, the first vacuum adsorption mold platform and the second vacuum adsorption mold platform are used to adsorb and position the mobile phone panel that has been attached with copper foil. This secondary attachment equipment is a secondary attachment equipment that is connected with the existing attachment equipment. It is mainly used to solve the problem of insufficient adhesion between the mobile phone panel and the corner area of ​​the copper foil.

[0012] Specifically, the device features a long-side rolling unit and two short-side rolling units arranged side-by-side. The long-side rolling unit primarily rolls along the long side of the phone panel, while the short-side rolling units roll along the short side, enabling rolling of the phone panel from two directions. Both the long-side and short-side rolling units include pressure-applying components. The pressure-applying components of the long-side rolling unit are located on the X-axis module, and those of the short-side rolling units are located on the Y-axis module. The power output end of each pressure-applying component houses a rolling module. Movement of the upper slide of the X-axis module drives the rolling module to roll along the X-axis, thus achieving adhesion reinforcement of the phone panel in the X-direction. Similarly, movement of the upper slide of the Y-axis module drives the rolling module to roll along the Y-direction, achieving adhesion reinforcement of the phone panel in the Y-direction. This allows for rolling of the phone panel in both length and width directions, solving the problem of insufficient adhesion in corner areas that exists in existing devices using unidirectional rolling. In addition, the setup of two short-side rolling units can achieve multiple rolling reinforcements in the short-side direction and ensure the continuity of the rolling process. This avoids the accumulation of products waiting to be rolled due to multiple rollings at a single rolling station, which would otherwise cause a long rolling time.

[0013] Since the long-side rolling unit and the short-side rolling unit respectively include a first vacuum adsorption mold platform and a second vacuum adsorption mold platform, the first vacuum adsorption mold platform and the second vacuum adsorption mold platform are used to adsorb and position the mobile phone panel with copper foil attached. The rolling module above the first vacuum adsorption mold platform extends along the long side of the mobile phone panel, and the rolling module above the second vacuum adsorption mold platform extends along the short side of the mobile phone panel. The first vacuum adsorption mold platform and the second vacuum adsorption mold platform are mainly used to adsorb and position the mobile phone panel with copper foil attached, so as to ensure the stability of the position during the subsequent rolling process of the mobile phone panel and avoid damage to the mobile phone panel due to position displacement during the rolling process. The different extension directions of the rolling module can match the shape of the mobile phone panel to achieve a more comprehensive rolling effect.

[0014] Furthermore, to ensure a good fit, the pressure required at the corners needs to be greater than the pressure applied to the plane. Existing equipment lacks phased pressure control, resulting in insufficient pressure at the corners. The pressure application component includes an electric cylinder bracket, a pneumatic cylinder bracket, a Z-axis servo electric cylinder, a pressure cylinder, and a pressure sensor. The electric cylinder bracket above the first vacuum adsorption mold platform is set on the X-axis module, and the electric cylinder bracket above the second vacuum adsorption mold platform is set on the corresponding Y-axis module. The Z-axis servo electric cylinder is mounted on the electric cylinder bracket, and the pneumatic cylinder bracket is located below the electric cylinder bracket with the two sliding vertically. The pressure cylinder is located at the lower end of the pneumatic cylinder bracket, and the pressure sensor is located between the telescopic rod of the Z-axis servo electric cylinder and the pneumatic cylinder bracket. The rolling module is located at the power output end of the pressure cylinder.

[0015] Furthermore, in order to accurately transfer the mobile phone panel to the next rolling process after completing one rolling process, including a first Y-axis module, a second Y-axis module, a third Y-axis module and a transport X-axis module, the first vacuum adsorption mold platform is set on the first slide of the first Y-axis module, and the two second vacuum adsorption mold platforms are respectively set on the first slides of the second Y-axis module and the third Y-axis module.

[0016] The two slides of the X-axis transport module are respectively equipped with a first T-axis servo motor, the output shaft of the first T-axis servo motor is equipped with a first lifting suction cup frame, and a vision light source is provided on one side of the first T-axis servo motor.

[0017] Alignment units are provided between the first Y-axis module and the second Y-axis module, and between the second Y-axis module and the third Y-axis module. Each alignment unit includes two first alignment cameras, which are used to photograph the two corners of the long side of the mobile phone panel adsorbed on the first lifting suction cup holder.

[0018] Furthermore, in order to accurately place the mobile phone panel onto the first vacuum adsorption mold platform so that the subsequent rolling process can be completed smoothly, an automatic alignment seat is provided on the second slide of the first Y-axis module. The automatic alignment seat is provided with the first vacuum adsorption platform. The first vacuum adsorption platform is used to place the mobile phone panel with copper foil attached. Two second alignment cameras are provided above the first vacuum adsorption platform. The two second alignment cameras are used to photograph the two corners of the long side of the mobile phone panel on the first vacuum adsorption platform.

[0019] Furthermore, in order to transfer the mobile phone panel on the first vacuum adsorption platform to the first vacuum adsorption mold platform, a second lifting suction cup frame is provided between the first vacuum adsorption platform and the first vacuum adsorption mold platform. The second lifting suction cup frame is used to adsorb the mobile phone panel from the first vacuum adsorption platform.

[0020] Furthermore, it also includes an X-axis first detection module and a detection unit. The X-axis first detection module is located above the middle of the second Y-axis module and the third Y-axis module. The X-axis first detection module is equipped with a third lifting suction cup bracket. The detection unit includes a front appearance inspection camera and an AOI precision inspection camera. A second vacuum adsorption platform is provided on the second slide of the second Y-axis module. The second vacuum adsorption platform passes under the front appearance inspection camera and the AOI precision inspection camera in sequence. The two AOI precision inspection cameras capture the two edge distances in the width direction of the mobile phone panel from top to bottom. The edge distance is also the distance between the copper foil and the edge of the mobile phone panel. A coaxial light source is provided below the AOI precision inspection camera, and a ring light source is provided below the coaxial light source.

[0021] Existing attachment equipment only uses a single AOI for detection, with only coaxial light and a single image capture, resulting in poor detection accuracy. In this technical solution, two images are captured at each of the two edge positions in the width direction. The two images require switching between different light sources, namely, switching between coaxial light and ring light. By analyzing the two images captured at the same position, more accurate detection results can be obtained.

[0022] In addition, existing bonding equipment cannot detect appearance defects. In this technical solution, as the mobile phone panel moves under the front appearance inspection camera, the front appearance inspection camera takes pictures covering an effective field of view of 115mm*85mm. Two shots are enough to complete the acquisition of all images of the mobile phone panel. The appearance inspection results are obtained by analyzing the acquired appearance images.

[0023] Furthermore, in order to detect the curved edge of the curved mobile phone panel and set the curved edge detection path more compactly, a first Y-axis conveying module and an X-axis second detection module are also included. The first Y-axis conveying module is equipped with a second T-axis servo motor, and a fourth lifting suction cup frame is eccentrically provided on the output shaft of the second T-axis servo motor. The fourth lifting suction cup frame moves the mobile phone panel of the second vacuum adsorption platform above the X-axis second detection module.

[0024] A third vacuum adsorption platform is provided on the slide of the second X-axis detection module. An arc edge appearance detection unit is provided in the middle of the second X-axis detection module. The arc edge appearance detection unit includes two angle adjustment devices. The angle adjustment directions of the two angle adjustment devices are opposite. An arc edge detection camera is provided on the angle adjustment device. The angle of the two arc edge detection cameras is adjusted by the angle adjustment device until the shooting angle is facing the two curved surfaces of the mobile phone panel on the third vacuum adsorption platform.

[0025] Furthermore, in order to transfer the mobile phone panels that meet the quality requirements to the next process while improving the compactness of the equipment structure, a second Y-axis conveying module is also included. The second Y-axis conveying module is equipped with a third T-axis servo motor. The output shaft of the third T-axis servo motor is equipped with a fifth lifting suction cup frame. The second slide of the third Y-axis module is equipped with a fourth vacuum adsorption platform. The fifth lifting suction cup frame moves the mobile phone panels on the third vacuum adsorption platform to the fourth vacuum adsorption platform.

[0026] Above the third Y-axis module is a first X-axis discharge module, and on the first X-axis discharge module is a sixth lifting suction cup frame, which removes the mobile phone panel from the fourth vacuum adsorption platform.

[0027] Above the second X-direction detection module is a second X-direction discharge module, and on the second X-direction discharge module is a seventh lifting suction cup frame. The seventh lifting suction cup frame moves the NG mobile phone panel from the third vacuum adsorption platform to the NG product carrier platform.

[0028] Furthermore, in order to enable fine-tuning of the vacuum adsorption mold platform as needed, both the first and second vacuum adsorption mold platforms are equipped with an XYT manual fine-tuning platform at their lower ends.

[0029] Furthermore, existing slender rolling shafts are prone to deformation in the middle after prolonged use, affecting the overall rolling effect. The rolling module includes a rolling shaft and a rolling base. The two ends of the rolling shaft are rotatably connected to the two ends of the rolling base. The rolling base is provided with connecting shafts on both sides of the rolling shaft near the top. Several rolling bearings are spaced apart on the connecting shafts. The spaced rolling bearings provide multi-point support and improve the service life of the rolling module.

[0030] The beneficial effects of this invention are as follows: In this technical solution, the first vacuum adsorption mold platform and the second vacuum adsorption mold platform are used to adsorb and position the mobile phone panel that has been attached with copper foil. This secondary attachment equipment is a secondary attachment equipment that is connected with the existing attachment equipment. It is mainly used to solve the problem of insufficient adhesion between the mobile phone panel and the corner area of ​​the copper foil.

[0031] Specifically, the device features a long-side rolling unit and two short-side rolling units arranged side-by-side. The long-side rolling unit primarily rolls along the long side of the phone panel, while the short-side rolling units roll along the short side, enabling rolling of the phone panel from two directions. Both the long-side and short-side rolling units include pressure-applying components. The pressure-applying components of the long-side rolling unit are located on the X-axis module, and those of the short-side rolling units are located on the Y-axis module. The power output end of each pressure-applying component houses a rolling module. Movement of the upper slide of the X-axis module drives the rolling module to roll along the X-axis, thus achieving adhesion reinforcement of the phone panel in the X-direction. Similarly, movement of the upper slide of the Y-axis module drives the rolling module to roll along the Y-direction, achieving adhesion reinforcement of the phone panel in the Y-direction. This allows for rolling of the phone panel in both length and width directions, solving the problem of insufficient adhesion in corner areas that exists in existing devices using unidirectional rolling. In addition, the setup of two short-side rolling units can achieve multiple rolling reinforcements in the short-side direction and ensure the continuity of the rolling process. This avoids the accumulation of products waiting to be rolled due to multiple rollings at a single rolling station, which would otherwise cause a long rolling time.

[0032] Since the long-side rolling unit and the short-side rolling unit respectively include a first vacuum adsorption mold platform and a second vacuum adsorption mold platform, the first vacuum adsorption mold platform and the second vacuum adsorption mold platform are used to adsorb and position the mobile phone panel with copper foil attached. The rolling module above the first vacuum adsorption mold platform extends along the long side of the mobile phone panel, and the rolling module above the second vacuum adsorption mold platform extends along the short side of the mobile phone panel. The first vacuum adsorption mold platform and the second vacuum adsorption mold platform are mainly used to adsorb and position the mobile phone panel with copper foil attached, so as to ensure the stability of the position during the subsequent rolling process of the mobile phone panel and avoid damage to the mobile phone panel due to position displacement during the rolling process. The different extension directions of the rolling module can match the shape of the mobile phone panel to achieve a more comprehensive rolling effect. Attached Figure Description

Detailed Implementation

[0056] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0057] Example 1:

[0058] like Figure 1 , Figure 15 , Figure 16 As shown, this embodiment provides a secondary bonding device for flexible transparent materials, including an X-axis module 1, a Y-axis module 2, and a long-side rolling unit 3 and two short-side rolling units 4 arranged side by side. The X-axis module 1 is located above the long-side rolling unit 3, and the two Y-axis modules 2 are respectively located above the two short-side rolling units 4.

[0059] Both the long-side rolling unit 3 and the short-side rolling unit 4 include a pressure-applying component. The pressure-applying component of the long-side rolling unit 3 is disposed on the X-axis module 1, and the pressure-applying component of the short-side rolling unit 4 is disposed on the Y-axis module 2. Figure 3 As shown, the power output end of the pressure application component is equipped with a rolling module 5;

[0060] like Figure 1 As shown, the long-side rolling unit 3 and the short-side rolling unit 4 respectively include a first vacuum adsorption mold platform 6 and a second vacuum adsorption mold platform 7. The first vacuum adsorption mold platform 6 and the second vacuum adsorption mold platform 7 are used to adsorb and position the mobile phone panel 8 with copper foil attached. The rolling module 5 above the first vacuum adsorption mold platform 6 extends along the long side of the mobile phone panel 8, and the rolling module 5 above the second vacuum adsorption mold platform 7 extends along the short side of the mobile phone panel 8.

[0061] In this technical solution, the first vacuum adsorption mold platform 6 and the second vacuum adsorption mold platform 7 are used to adsorb and position the mobile phone panel 8 that has been attached with copper foil. This secondary attachment equipment is a secondary attachment equipment that connects with the existing attachment equipment (primary attachment). It is mainly used to solve the problem of insufficient adhesion between the mobile phone panel 8 and the corner area of ​​the copper foil.

[0062] Specifically, since the long side rolling unit 3 and two short side rolling units 4 are arranged side by side, the long side rolling unit 3 is mainly used to roll along the long side of the mobile phone panel 8, and the short side rolling unit 4 is mainly used to roll along the short side of the mobile phone panel 8, so that the mobile phone panel 8 can be rolled from two directions. Specifically, since both the long-side rolling unit 3 and the short-side rolling unit 4 include pressure-applying components, the pressure-applying components of the long-side rolling unit 3 are located on the X-direction module 1, and the pressure-applying components of the short-side rolling unit 4 are located on the Y-direction module 2. The power output end of the pressure-applying components is equipped with a rolling module 5. By moving the slide on the X-direction module 1, the rolling module 5 is driven to roll along the X-direction, thereby achieving reinforcement of the phone panel 8 in the X-direction. Similarly, by moving the slide on the Y-direction module 2, the rolling module 5 is driven to roll along the Y-direction, thereby achieving reinforcement of the phone panel 8 in the Y-direction. This allows for rolling of the phone panel 8 in both the length and width directions, solving the problem of insufficient adhesion in corner areas that exists in existing equipment using unidirectional (length direction) rolling. Furthermore, the arrangement of two short-side rolling units 4 allows for multiple rolling reinforcements in the short-side direction and ensures the continuity of the rolling process, avoiding the accumulation of products awaiting rolling due to multiple rolling operations at a single rolling station.

[0063] Since the long-side rolling unit 3 and the short-side rolling unit 4 respectively include a first vacuum adsorption mold platform 6 and a second vacuum adsorption mold platform 7, the first vacuum adsorption mold platform 6 and the second vacuum adsorption mold platform 7 are used to adsorb and position the mobile phone panel 8 with copper foil attached. The rolling module 5 above the first vacuum adsorption mold platform 6 extends along the long side of the mobile phone panel 8, and the rolling module 5 above the second vacuum adsorption mold platform 7 extends along the short side of the mobile phone panel 8. The first vacuum adsorption mold platform 6 and the second vacuum adsorption mold platform 7 are mainly used to adsorb and position the mobile phone panel 8 with copper foil attached, so as to ensure the stability of the position during the subsequent rolling process of the mobile phone panel 8 and avoid damage to the mobile phone panel 8 due to position displacement during the rolling process. The different extension directions of the rolling module 5 can match the shape of the mobile phone panel 8 to achieve a more comprehensive rolling effect.

[0064] Example 2:

[0065] This embodiment is an optimization based on the above embodiment one.

[0066] like Figure 1 , Figure 3As shown, to ensure a good fit, the pressure required at the corners needs to be greater than the pressure applied to the plane. Existing equipment lacks phased pressure control, resulting in insufficient pressure at the corners. The pressure application components include an electric cylinder bracket 9, a pneumatic cylinder bracket 10, a Z-axis servo electric cylinder 11, a pressure cylinder 12, and a pressure sensor 13. The electric cylinder bracket 9 above the first vacuum adsorption mold platform 6 is set on the X-axis module 1, and the electric cylinder bracket 9 above the second vacuum adsorption mold platform 7 is set on the corresponding Y-axis module 2. The Z-axis servo electric cylinder 11 is mounted on the electric cylinder bracket 9, and the pneumatic cylinder bracket 10 is located below the electric cylinder bracket 9 and the two slide vertically together. Specifically, the pneumatic cylinder bracket 10 is provided with a guide post 14, which slides vertically with the electric cylinder bracket 9. The pressure cylinder 12 is set at the lower end of the pneumatic cylinder bracket 10, and the pressure sensor 13 is set between the telescopic rod of the Z-axis servo electric cylinder 11 and the pneumatic cylinder bracket 10. The rolling module 5 is set at the power output end of the pressure cylinder 12.

[0067] In existing technologies, the control force of the rolling roller is fixed, meaning that the rolling roller is extended by a cylinder for rolling. During this process, it is impossible to monitor the rolling pressure or adjust it according to different rolling strokes. Therefore, insufficient pressing in corner areas can occur. In this technical solution, the rolling module 5 receives pressure feedback from the pressure sensor 13 during its movement. The PLC controller uses this real-time pressure feedback to control the pressure cylinder 12, thereby controlling the rolling pressure and improving the pressing effect in corner areas.

[0068] It should be noted that the rolling module 5 is a detachable component. For different product models, the corresponding rolling module 5 can be replaced. The pressure cylinder 12 controls the air pressure inside it through a proportional valve to achieve stable rolling pressure. The pressure can be controlled by a PLC (0-35Kg). A pressure sensor 13 is installed above the pressure cylinder 12 to achieve closed-loop control and monitor the pressure value during rolling in real time.

[0069] Example 3:

[0070] This embodiment is an optimization based on the above embodiment one.

[0071] like Figure 1 , Figure 6 , Figure 7 As shown, in order to accurately transfer the mobile phone panel 8 to the next rolling process after completing one rolling process, the system includes a first Y-axis module 15, a second Y-axis module 16, a third Y-axis module 17 and a transport X-axis module 18. The first vacuum adsorption mold platform 6 is set on the first slide of the first Y-axis module 15, and the two second vacuum adsorption mold platforms 7 are respectively set on the first slides of the second Y-axis module 16 and the third Y-axis module 17.

[0072] like Figure 6 As shown, the two slides of the X-axis transport module 18 are respectively equipped with a first T-axis servo motor 19. The T-axis adjustment of the mobile phone panel 8 is controlled and corrected by the first T-axis servo motor 19. The T-axis is the rotation direction. The output shaft of the first T-axis servo motor 19 is equipped with a first lifting suction cup frame 20. A visual light source 21 is provided on one side of the first T-axis servo motor 19.

[0073] like Figure 7 As shown, alignment units 22 are respectively provided between the first Y-axis module 15 and the second Y-axis module 16, and between the second Y-axis module 16 and the third Y-axis module 17. Each alignment unit 22 includes two first alignment cameras 23, which are used to photograph the two corners of the long side of the mobile phone panel 8 adsorbed on the first lifting suction cup holder 20. The two first alignment cameras 23 are mounted on the Y-axis slide rail 25 via a manual alignment stage 24, and the distance between the two first alignment cameras 23 is adjustable.

[0074] Specifically, after the mobile phone panel 8 on the first vacuum adsorption mold platform 6 completes the length-direction rolling, the first vacuum adsorption mold platform 6 moves to the lower part of the first lifting suction cup frame 20 on the left side of the transport X-axis module 18. The first lifting suction cup frame 20 descends and adsorbs the mobile phone panel 8, then moves the mobile phone panel 8 upwards, and moves it with the mobile phone panel 8 to the alignment unit 22 between the first Y-axis module 15 and the second Y-axis module 16, as shown. Figure 11 As shown, the two first alignment cameras 23 take pictures from bottom to top. At the same time, the first T-axis servo motor 19 above the alignment unit 22 rotates to adjust the angle of the mobile phone panel 8 on the horizontal plane until the two first alignment cameras 23 capture the two corner points of the long side of the mobile phone panel 8. Then, the slide table on the left side of the X-axis module 18 is moved to the top of the second Y-axis module 16, the second vacuum adsorption mold platform 7 is moved to the receiving station of the second Y-axis module 16, and the first lifting suction cup frame 20 on the left side of the X-axis module 18 lowers the mobile phone panel 8 to the second vacuum adsorption mold platform. On the 7th, the second vacuum adsorption mold platform 7 moves to the rolling station of the second Y-axis module 16. The mobile phone panel 8 completes the short side rolling at the rolling station. Then, the first lifting suction cup frame 20 on the right side of the transport X-axis module 18 transfers the mobile phone panel 8, which has completed the short side rolling, to the alignment unit 22 between the second Y-axis module 16 and the third Y-axis module 17. The above alignment operation is repeated. Then, the first lifting suction cup frame 20 on the right side of the transport X-axis module 18 transfers the mobile phone panel 8 to the rolling station of the third Y-axis module 17, and completes the short side rolling again.

[0075] The motors of the first Y-axis module 15, the second Y-axis module 16, the third Y-axis module 17, and the transport X-axis module 18 are all linear motors, which have high repeatability and high speed, ensuring that the single alignment time is controlled within 0.4s.

[0076] After the first lifting suction cup frame 20 picks up the product, it moves to the photo-taking position and takes a photo from bottom to top to fix the position. The required correction value is then sent to the PLC. The PLC corrects the X, T, and Y directions by using the X-axis linear motor of the X-axis module 18, the first T-axis servo motor 19, and the Y-axis linear motor of the second Y-axis module 16.

[0077] Example 4:

[0078] This embodiment is an optimization based on the above embodiment three.

[0079] like Figure 7 As shown, in order to accurately place the mobile phone panel 8 onto the first vacuum adsorption mold platform 6 for the smooth completion of the subsequent rolling process, an automatic alignment seat 54 is provided on the second slide of the first Y-axis module 15. The automatic alignment seat 54 is equipped with a first vacuum adsorption platform 26, which is used to place the mobile phone panel 8 with copper foil already attached. Figure 1 As shown, two second alignment cameras 27 are installed above the first vacuum adsorption platform 26, as... Figure 17 As shown, two second alignment cameras 27 are used to photograph two corner points A of the long side of the mobile phone panel 8 on the first vacuum adsorption platform 26. Figure 8 As shown, the two second-aligned cameras 27 can be manually adjusted by adjusting the slide 55 to adjust the position of the cameras in the X / Y / Z directions, ensuring that the two corner points A in the length direction of the receiving mobile phone panel 8 are always within the field of vision.

[0080] Specifically, the two second alignment cameras 27 take pictures from top to bottom. At the same time, the automatic alignment mount 54 automatically adjusts the angle of the mobile phone panel 8 until the two second alignment cameras 27 capture the two corner points of the long side of the mobile phone panel 8. The automatic alignment mount 54 then stops, and the position of the mobile phone panel 8 is maintained, pending subsequent transfer work.

[0081] Example 5:

[0082] This embodiment is an optimization based on the above embodiment four.

[0083] In order to transfer the mobile phone panel 8 from the first vacuum adsorption platform 26 to the first vacuum adsorption mold platform 6, such as Figure 1 , Figure 8 As shown, a second lifting suction cup frame 28 is provided between the first vacuum adsorption platform 26 and the first vacuum adsorption mold platform 6. The second lifting suction cup frame 28 is used to adsorb the mobile phone panel 8 from the first vacuum adsorption platform 26.

[0084] Specifically, the first vacuum adsorption platform 26 moves below the second lifting suction cup frame 28, the second lifting suction cup frame 28 adsorbs the mobile phone panel 8, then the first vacuum adsorption platform 26 returns to its original position, the first vacuum adsorption mold platform 6 moves below the second lifting suction cup frame 28, the second lifting suction cup frame 28 places the mobile phone panel 8 on the first vacuum adsorption mold platform 6, and the first vacuum adsorption mold platform 6 moves to the rolling station of the first Y-axis module 15.

[0085] Example 6:

[0086] This embodiment is an optimization based on the above embodiment one.

[0087] like Figure 1 , Figure 8 , Figure 20 As shown, it also includes an X-axis first detection module 29 and a detection unit. The X-axis first detection module 29 is located above the middle of the second Y-axis module 16 and the third Y-axis module 17. A third lifting suction cup bracket 30 is provided on the X-axis first detection module 29. The detection unit includes a front appearance detection camera 31 and an AOI precision detection camera 32. A second vacuum adsorption platform 33 is provided on the second slide of the second Y-axis module 16. The second vacuum adsorption platform 33 passes under the front appearance detection camera 31 and the AOI precision detection camera 32 in sequence. The two AOI precision detection cameras 32 photograph the two edge distances in the width direction of the mobile phone panel 8 from top to bottom. The edge distance is also the distance between the copper foil and the edge of the mobile phone panel 8. A coaxial light source 34 is provided below the AOI precision detection camera 32. A ring light source 35 is provided below the coaxial light source 34.

[0088] The existing attachment equipment only sets up a single AOI detection in the detection process, and only uses coaxial light. It only takes one image, resulting in poor detection accuracy. In this technical solution, two images are taken at the two edge positions in the width direction. The two images need to switch between different light sources, that is, switching between coaxial light source 34 and ring light source 35. By analyzing the two images taken at the same position, more accurate detection results can be obtained.

[0089] In addition, such as Figure 18 , Figure 19 As shown, existing bonding equipment cannot detect appearance defects. In this technical solution, as the mobile phone panel 8 moves under the front appearance inspection camera 31, the front appearance inspection camera 31 can take pictures that cover an effective field of view of 115mm*85mm. Two shots are enough to complete the acquisition of all images of the mobile phone panel 8. The appearance inspection results are obtained by analyzing the acquired appearance images.

[0090] Example 7:

[0091] This embodiment is an optimization based on the above embodiment six.

[0092] like Figure 1 , Figure 8 , Figure 10 As shown, in order to detect the curved edge of the curved mobile phone panel 8 and to set the curved edge detection path more compactly, a first Y-axis conveying module 36 and an X-axis second detection module 37 are also included. The first Y-axis conveying module 36 is equipped with a second T-axis servo motor 38. The output shaft of the second T-axis servo motor 38 is eccentrically equipped with a fourth lifting suction cup 39. The eccentric structure can adjust the rotation direction and landing point of the product to avoid interference from the curved edge appearance detection unit 41. The fourth lifting suction cup 39 moves the mobile phone panel 8 of the second vacuum adsorption platform 33 above the X-axis second detection module 37.

[0093] A third vacuum adsorption platform 40 is provided on the slide of the second detection module 37 in the X direction, and an arc-edge appearance detection unit 41 is provided in the middle of the second detection module 37 in the X direction, such as Figure 9 As shown, the arc edge appearance detection unit 41 includes two angle adjustment devices 42. The angle adjustment directions of the two angle adjustment devices 42 are opposite. An arc edge detection camera 43 is provided on the angle adjustment device 42. The angle of the two arc edge detection cameras 43 is adjusted by the angle adjustment device 42 until the shooting angle is directed towards the two curved surfaces of the mobile phone panel 8 on the third vacuum adsorption platform 40.

[0094] like Figure 2 , Figure 9 As shown, the angle adjustment device 42 includes an arc-shaped track 42.1 and a track slider 42.2. The arc-shaped edge detection camera 43 is mounted on the track slider 42.2. The track slider 42.2 moves along the arc-shaped track 42.1. Once the arc-shaped slider reaches a suitable position on the arc-shaped track 42.1, its position on the track 42.1 is fixed, thus ensuring the stability of the shooting angle of the arc-shaped edge detection camera 43. It should be noted that the position of the angle adjustment device 42 in the Y direction is adjustable, allowing for adjustment of the position of the arc-shaped edge detection camera 43 as needed.

[0095] Specifically, such as Figure 1 , Figure 8As shown, the slide on the first Y-axis conveying module 36 drives the second T-axis servo motor 38 and the fourth lifting suction cup 39 to move above the second vacuum adsorption platform 33. The fourth lifting suction cup 39 is in the material picking state, which is achieved by rotating the second T-axis servo motor 38 by 90 degrees, so that the fourth lifting suction cup 39 can adsorb the mobile phone panel 8 whose length direction is consistent with the Y-axis. After picking up the material, the fourth lifting suction cup 39 moves above the X-axis second detection module 37 and then releases the material. In the material releasing state, the second T-axis servo motor 38 drives the fourth lifting suction cup 39 to rotate 90 degrees, so that the length direction of the fourth lifting suction cup 39 is consistent with the length direction of the X-axis second detection module 37. This allows the mobile phone panel 8, which has been adjusted in direction (rotated 90 degrees), to be placed on the third vacuum adsorption platform 40 for subsequent arc edge detection.

[0096] During specific arc edge detection, the angle adjustment device 42 adjusts the angle of the arc edge detection camera 43. The two angle adjustment devices 42 adjust in opposite directions, such as... Figure 21 As shown, the angles of the two curved edge detection cameras 43 are adjusted by the angle adjustment device 42 until the shooting angle faces the two curved surfaces of the mobile phone panel 8 on the third vacuum adsorption platform 40. As the third vacuum adsorption platform 40 moves along the X-axis towards the second detection module 37, simultaneous detection of the two curved edges on the mobile phone panel 8 is achieved. That is, one curved edge detection camera 43 corresponds to one curved edge of the mobile phone panel 8, and the left and right curved edges correspond to the two curved edge detection cameras 43 respectively. By using a flying camera, image acquisition can be completed quickly.

[0097] Specifically, the X-axis second inspection module 37 uses two sets of linear motors, and the curved edge inspection camera 43 uses a high-frequency area array camera to capture images while the product is in motion. The product's moving speed is 2m / s, and the camera and light source can be adjusted ±45° to meet the inspection requirements of curved surface products within 85°. The inspection results are then output to the PLC. The PLC uses the inspection results from three vision systems (front appearance inspection, AOI precision inspection, and curved edge inspection) to distribute the materials to different workstations. OK products flow to the unloading unit, and NG products flow to the NG platform.

[0098] Example 8:

[0099] This embodiment is an optimization based on the above embodiment seven.

[0100] In order to transfer the mobile phone panels 8 that meet the quality requirements to the next process while improving the compactness of the equipment structure, such as Figure 1As shown, it also includes a second Y-axis conveying module 44, a third T-axis servo motor 45 is provided on the second Y-axis conveying module 44, a fifth lifting suction cup frame 46 is provided on the output shaft of the third T-axis servo motor 45, a fourth vacuum adsorption platform 47 is provided on the second slide of the third Y-axis module 17, and the fifth lifting suction cup frame 46 moves the mobile phone panel 8 on the third vacuum adsorption platform 40 to the fourth vacuum adsorption platform 47.

[0101] like Figure 8 As shown, a first X-axis discharge module 48 is provided above the third Y-axis module 17, and a sixth lifting suction cup frame 49 is provided on the first X-axis discharge module 48. The sixth lifting suction cup frame 49 removes the mobile phone panel 8 from the fourth vacuum adsorption platform 47.

[0102] like Figure 14 As shown, a second X-direction discharge module 50 is provided above the second X-direction detection module 37. A seventh lifting suction cup frame 51 is provided on the second X-direction discharge module 50. The seventh lifting suction cup frame 51 moves the NG mobile phone panel 8 on the third vacuum adsorption platform 40 to the NG product carrier platform 52.

[0103] Specifically, such as Figure 1 , Figure 8 , Figure 10 , Figure 12 As shown, the slide on the second Y-axis conveying module 44 drives the third T-axis servo motor 45 and the fifth lifting suction cup 46 to move above the third vacuum adsorption platform 40. The fifth lifting suction cup 46 is in the material picking state, which is achieved by rotating the third T-axis servo motor 45 by 90 degrees, so that the fifth lifting suction cup 46 can adsorb the mobile phone panel 8 whose length direction is consistent with the X-axis. The slide on the second Y-axis conveying module 44 drives the third T-axis servo motor 45 and the fourth lifting suction cup 39 to move above the third Y-axis module 17 to prepare for material placement. The third T-axis servo motor 45 drives the fifth lifting suction cup 46 to rotate 90 degrees, so that the length direction of the fifth lifting suction cup 46 is consistent with the length direction of the third Y-axis module 17, thereby enabling the adjusted mobile phone panel 8 to be placed on the fourth vacuum adsorption platform 47 for subsequent material discharge.

[0104] The fourth vacuum adsorption platform 47 moves below the first X-direction discharge module 48, and the sixth lifting suction cup frame 49 moves the mobile phone panel 8 on the fourth vacuum adsorption platform 47 to the next device to complete the discharge.

[0105] If the arc-shaped edge detection result is unqualified, such as Figure 14 As shown, the seventh lifting suction cup frame 51 moves the NG mobile phone panel 8 on the third vacuum adsorption platform 40 to the NG product carrier platform 52. The NG product carrier platform 52 has a diffuse reflection sensor, which notifies the staff to unload the material when there is material.

[0106] In summary, this technical solution can complete the detection of the curved edges of the mobile phone panel and can automatically separate qualified and unqualified products (including front appearance inspection, AOI precision inspection and curved edge detection results).

[0107] Example 9:

[0108] This embodiment is an optimization based on the above embodiment one.

[0109] In order to enable fine-tuning of the vacuum adsorption mold platform as needed, such as Figure 1 , Figure 7 , Figure 10 , Figure 13 As shown, both the first vacuum adsorption mold platform 6 and the second vacuum adsorption mold platform 7 are equipped with an XYT manual fine-tuning platform 53 at their lower ends to ensure that the aligned product can be placed into the recessed part of the mold platform.

[0110] Example 10:

[0111] This embodiment is an optimization based on the above embodiment one.

[0112] Existing thin, elongated rolling rollers are prone to deformation in the middle after prolonged use, affecting the overall rolling effect. Figure 4 , Figure 5 As shown, the rolling module 5 includes a rolling shaft 5.1 and a rolling seat 5.2. The two ends of the rolling shaft 5.1 are rotatably connected to the two ends of the rolling seat 5.2. The rolling seat 5.2 is provided with connecting shafts 5.3 at the upper positions on both sides of the rolling shaft 5.1. Several rolling bearings 5.4 are spaced apart on the connecting shafts 5.3. The spaced rolling bearings 5.4 can provide multi-point support and improve the service life of the rolling module 5.

[0113] It should be noted that each process in this technical solution can be set up with two workstations to handle situations such as single material discharge, double material discharge, or mixed single and double material discharge from upstream.

[0114] It should be noted that the first lifting suction cup frame 20, the second lifting suction cup frame 28, the third lifting suction cup frame 30, the fourth lifting suction cup frame 39, the fifth lifting suction cup frame 46, the sixth lifting suction cup frame 49 and the seventh lifting suction cup frame 51 all use a fixed-point lifting cylinder 57 to drive the suction cup frame 58 to lift and transfer the product to the next process.

[0115] It should be noted that the top of the overall equipment also includes two EFUs. The top FFU is always on during equipment operation, drawing in air and filtering it through the primary and high-efficiency filters. The filtered clean air is then uniformly delivered across the entire air outlet surface at a wind speed of 0.45 m / s + 20%.

[0116] like Figure 3 As shown, both the long-side rolling unit 3 and the short-side rolling unit 4 are equipped with ion air bars 56, which ensure that the product is free of static electricity.

[0117] It should be noted that the visual single-shot time of the first alignment camera 23 and the second alignment camera 27 is 0.4 seconds, the pixel equivalent is 0.0074 mm / Pixel, and the visual alignment accuracy is ±0.037 mm (excluding device error).

[0118] It should be noted that the AOI precision inspection camera has a single image capture time of 0.5 seconds, a pixel equivalent of 4.8µm / pixel, and a detection accuracy of 10µm. Different light sources need to be switched during inspection to measure the product's margins.

[0119] It should be noted that the parameters of the front appearance inspection camera 31 are shown in Table 1:

[0120] Table 1

[0121]

[0122] It should be noted that the parameters of the curved edge detection camera 43 are shown in Table 2:

[0123] Table 2

[0124]

[0125] In practical implementation, the XY-axis transfer between different workstations of this equipment adopts linear modules, with three sets of alignment vision systems (including two alignment units 22 and a second alignment camera above the first vacuum adsorption platform) and three sets of inspection vision systems (including front appearance inspection, AOI precision inspection, and curved edge appearance inspection). Each unit consists of two channels (two workstations per process, which can work synchronously), capable of handling single-material, double-material, or mixed single-double-material discharge from upstream, and can be adjusted according to different product sizes to meet the production and inspection needs of different types of products from 3 to 8 inches. Before each rolling, the vision system performs alignment to ensure rolling accuracy and prevent the possibility of product breakage during rolling due to misalignment when placed inside the mold platform. The inspection vision system includes front appearance inspection, AOI precision inspection, and curved edge appearance inspection, which can detect defects such as substandard bonding accuracy, bubbles, bulges, and unevenness after product attachment, and classify them as OK / NG.

[0126] This technical solution uses a Keyence KV-8000 PLC as the control unit and a ProFix touchscreen to display relevant product information, detection parameters, and motion control functions. The alignment unit can communicate with the PLC to perform product alignment compensation during material cutting. The vision inspection system can detect defects such as bonding accuracy, bubbles, bulges, unevenness, and breakage, and finally return the inspection results to the PLC.

[0127] The overall movement of the equipment is achieved by controlling linear motors and servo motors via EtherCAT communication. For pressure control, analog communication is used to adjust the pressure of the long-side rolling and the two short-side rolling via three proportional valves, and the real-time pressure during rolling is returned to the PLC via pressure sensor 13.

[0128] The average production time for a single product is approximately 4.2 seconds, during which the alignment, rolling, inspection, and sorting processes are completed. The inspection frequency is 100% full inspection, preventing defective products from flowing to downstream equipment.

[0129] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0130] 1. The product is attached by rolling the long and short sides separately, which reduces the possibility of insufficient adhesion in the corner areas compared to rolling in one direction.

[0131] 2. Currently, the equipment is not compatible with the application of four-sided curved and two-sided curved mobile phone panels and heat dissipation film (copper foil). This equipment can not only meet the needs of flat screens, but also meet the secondary application and testing of 3-8 inch curved products within 85°. In specific operation, a matching vacuum adsorption mold platform can be replaced.

[0132] 3. The pressure can be controlled separately for long side rolling and short side rolling, adapting to different plane pressure and corner pressure parameters, reducing the occurrence of insufficient pressing in the four corner areas.

[0133] 4. For the bonding pressure of different work stations, a proportional valve is used to control the cylinder pressure, and a pressure sensor 13 is used to record the real-time pressure value during rolling.

[0134] 5. Three sets of visual inspection systems are used to visually inspect the front appearance, bonding accuracy, and curved edge appearance of the product, respectively. They can detect defects such as bonding accuracy, bubbles, bulges, and damage, with a detection rate of ≥99.95%.

[0135] The specific workflow of the equipment is as follows:

[0136] 1. After the first vacuum adsorption platform 26 receives the material from the upstream, the second alignment camera 27 performs visual alignment, and then the material is unloaded to the second lifting suction cup frame 28.

[0137] 2. The second lifting suction cup frame 28 transfers the product to the long side rolling unit 3, where the long side rolling unit 3 performs long side rolling attachment.

[0138] 3. After the long side is rolled and attached, the product is unloaded to the first lifting suction cup frame 20 on the left. The first lifting suction cup frame 20 moves the product above the alignment unit 22 on the left for visual alignment. Then the first lifting suction cup frame 20 places the product on the second vacuum adsorption mold platform 7 on the second Y-axis module 16, and the short side rolling unit 4 performs short side rolling.

[0139] 4. After short-side rolling and attachment, the product is unloaded to the first lifting suction cup frame 20 on the right. The first lifting suction cup frame 20 moves the product above the alignment unit 22 on the right for visual alignment. Then, the first lifting suction cup frame 20 places the product on the second vacuum adsorption mold platform 7 on the third Y-axis module 17. After the short-side rolling unit 4 performs short-side rolling, the product is unloaded to the third lifting suction cup frame 30.

[0140] 5. The third lifting suction cup frame 30 transfers the product to the front appearance inspection camera 31 and AOI precision inspection camera 32 to inspect the front appearance and attachment precision of the product. After inspection, the results are output to the PLC and the product is unloaded to the fourth lifting suction cup frame 39.

[0141] 6. The fourth lifting suction cup frame 39 transfers the product to the third vacuum adsorption platform 40. The arc edge appearance inspection unit 41 performs arc edge appearance inspection on the product. After inspection, the inspection result is output to the PLC. The PLC determines that the front appearance, AOI accuracy, and arc edge appearance are all OK, and then unloads the product to the fifth lifting suction cup frame 46. If any of the three conditions of front appearance, AOI accuracy, or arc edge appearance is NG, the product is unloaded to the NG product carrier platform 52 by the seventh lifting suction cup frame 51, and then picked up by the staff.

[0142] 7. If the front appearance, AOI accuracy, and curved edge appearance are all qualified, the fifth lifting suction cup frame 46 will move the product to the fourth vacuum adsorption platform 47.

[0143] 8. The sixth lifting suction cup frame 49 transports the product on the fourth vacuum adsorption platform 47 to the downstream equipment.

[0144] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
