Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid crystal panel processing, in particular to a liquid crystal panel film separation and conveying system and an automatic separation method thereof. BACKGROUND

[0002] The liquid crystal panel film is a functional film attached to the surface of the liquid crystal panel to give it optical properties or protective functions. The two are combined through a glue layer or electrostatic adsorption to form a key structure of the liquid crystal display device. The use of a liquid crystal panel film separation and conveying system in the production process of the liquid crystal panel can accurately separate and convey various functional films without damaging the panel substrate, thereby achieving efficient and high-precision peeling and conveying of the film.

[0003] However, in the prior art, the molecular-level interaction between the film and the glue layer and the characteristics of the glue layer itself, as well as the interlayer stress of the multi-layer film structure and the change of the environmental temperature and humidity, can exacerbate the adhesion difference, resulting in damage to the liquid crystal panel film during separation and conveying. The prior art usually uses a method of moving the film from one side to the other side to separate and convey the film. This method can increase the lifting height of one side of the film, causing excessive stress on the film and the substrate. Moreover, it is difficult to accurately control the force and angle. When separating and conveying the film and the substrate that can be recycled, the concentration of mechanical stress can cause damage to the film or the substrate, making it impossible to be reused.

[0013] An automated separation method for a liquid crystal panel film separation and handling system includes the following steps:

[0014] S1. Place the LCD panel on the upper part of the placement platform mechanism, and push and align the four sides of the LCD panel by adjusting the limiting plate in the mechanism to make the LCD panel upright on the upper part of the placement platform mechanism. Then, use the second suction cup assembly to adsorb and fix the bottom of the LCD panel.

[0015] S2. The image information of the fixed LCD panel on the upper part of the placement platform mechanism is acquired by an industrial camera, and the position and size information of the LCD panel are calculated by an external industrial control computer, and control commands are generated.

[0016] S3. The adsorption and fixing mechanism adjusts the position of the first suction cup component according to the control command, and at the same time, the three-axis conveying mechanism adjusts the position of the adsorption and fixing mechanism according to the control command, so that the first suction cup component is accurately adsorbed on the surface of the liquid crystal panel film.

[0017] S4. The adhesive layer interface between the liquid crystal panel and the film is processed by the auxiliary mechanism, and at the same time, the separation and fixing mechanism drives two sets of adsorption and fixing mechanisms to pull and separate the film on the surface of the liquid crystal panel from both ends in a synchronous manner.

[0018] S5. During the process of separating the film by the separation and fixing mechanism and the adsorption and fixing mechanism, the tension data of the first suction cup component is monitored by a six-dimensional force sensor. The speed at which the separation and fixing mechanism drives the adsorption and fixing mechanism to rise is automatically adjusted according to the tension data to avoid damage to the LCD panel and film caused by excessive tension.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, a servo motor drives a lead screw to move a wedge-shaped pusher block horizontally relative to the lead screw. The wedge-shaped pusher block slides in the guide groove of the lifting frame, converting the horizontal motion into the vertical lifting of the lifting frame, thereby achieving indirect linear pulling of the diaphragm, improving the control accuracy during pulling, and avoiding a sudden increase in tension. The two sets of adsorption and fixing mechanisms are synchronously driven by the lead screw block to separate and transport the diaphragm from both ends, solving the problem of diaphragm warping and deformation caused by unilateral separation. At the same time, it avoids excessive stress on the substrate when the diaphragm is torn off, which could damage the substrate. The auxiliary mechanism moves synchronously with the adsorption and fixing mechanism. The degumming component processes the adhesive layer interface in real time, improving separation stability. The adsorption and fixing mechanism has a built-in six-dimensional force sensor to achieve precise sensing and flexible control of the separation force, ultimately significantly reducing the risk of diaphragm breakage and improving separation and transport efficiency and accuracy.

[0021] 2. In this invention, the telescopic component of the adjustment mechanism drives the limiting plate to be positioned and centered. Combined with the visual inspection of the industrial camera, it ensures the precise placement of the LCD panel on the placement platform mechanism. The buffer component and the second suction cup component of the placement platform mechanism realize the flexible fixation and adsorption of the panel, avoiding damage from rigid contact. The six-dimensional force sensor monitors the adsorption force in real time and controls the servo motor, Z-axis movement component and drive component in linkage. Through multi-axis collaborative adjustment of the tension threshold, the force control of the film separation process is refined. The redundant lifting design can dynamically adjust the separation strategy for different adhesive layer characteristics, significantly improving the separation efficiency of films without adhesive layers. Finally, a closed-loop control of the entire process from positioning, adsorption to separation is formed, taking into account both accuracy and efficiency.

[0022] 3. In this invention, the ultrasonic vibration module, laser-induced heating module, and electrostatic elimination module in the degumming assembly can respectively weaken the van der Waals force between the membrane and the adhesive layer through high-frequency vibration, reduce the viscosity of the adhesive layer through micro-area heating, and eliminate static electricity to prevent secondary adhesion. The synergistic effect of multiple physical fields reduces the adhesion force of the adhesive layer. The No. 3 wire block rotates synchronously with the No. 1 lead screw, driving the No. 5 mounting frame and the degumming assembly to move, ensuring that the degumming process and the separation action of the adsorption and fixing mechanism are matched in real time, realizing dynamic pretreatment of the adhesive layer interface. The non-contact degumming process avoids the damage to the membrane caused by traditional mechanical peeling. Combined with the real-time force control of the six-dimensional force sensor, the separation reliability and production efficiency are significantly improved. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Refer to Figures 1-6As shown: A liquid crystal panel film separation and handling system includes a three-axis handling mechanism 1 for handling liquid crystal panel films. The bottom of the three-axis handling mechanism 1 is provided with a placement platform mechanism 4 for fixing the liquid crystal panel. The end of the three-axis handling mechanism 1 is fixedly connected to a separation and fixing mechanism 2. The separation and fixing mechanism 2 includes a fixing plate 21. The bottom of the fixing plate 21 is fixedly connected to a second mounting bracket 22. The end of the second mounting bracket 22 is equipped with a servo motor 23. The output end of the servo motor 23 is fixedly connected to a first lead screw 24. The surface of the first lead screw 24 is provided with two threads with opposite directions. The two threads with opposite directions are respectively equipped with first screw blocks 25. The upper part of the first screw block 25 is fixedly connected to a wedge-shaped push block 26. The upper part of the wedge-shaped push block 26 is slidably connected to a lifting frame 27. The inside of the lifting frame 27 is provided with a guide groove adapted to the wedge-shaped push block 26. The side of the lifting frame 27 is fixedly connected to a connecting frame 28. The bottom of the connecting frame 28 is fixedly connected to an adsorption and fixing mechanism 3 for fixing the liquid crystal panel film.

[0036] The separation and fixing mechanism 2 is equipped with an auxiliary mechanism 7 for removing the adhesive from the liquid crystal panel film. The separation and fixing mechanism 2 is used to drive the adsorption and fixing mechanism 3 to move up and down, and the separation and fixing mechanism 2 is used to drive the auxiliary mechanism 7 to move horizontally in sync with the up and down movement of the adsorption and fixing mechanism 3. A telescopic rod 29 is fixedly connected to the upper part of the connecting frame 28. The telescopic rod 29 is fixedly connected to the bottom of the fixing plate 21, and a spring 210 is provided on the surface of the telescopic rod 29. One end of the spring 210 is fixedly connected to the connecting frame 28, and the other end of the spring 210 is fixedly connected to the bottom of the fixing plate 21.

[0037] The adsorption and fixing mechanism 3 includes a second X-axis moving component 31, a second Y-axis moving component 32 is fixedly connected to the moving end of the second X-axis moving component 31, a first suction cup component 33 is fixedly connected to the moving end of the second Y-axis moving component 32, and a six-dimensional force sensor 8 is installed on the upper part of the first suction cup component 33. The three-axis conveying mechanism 1 includes a first X-axis moving component 11, a first Y-axis moving component 12 is installed on the moving end of the first X-axis moving component 11, a Z-axis moving component 13 is installed on the moving end of the first Y-axis moving component 12, a first mounting frame 14 is fixedly connected to the moving end of the Z-axis moving component 13, and the bottom of the first mounting frame 14 is fixedly connected to the fixing plate 21.

[0038] In this embodiment, the servo motor 23 drives the first lead screw 24 to rotate, causing the two first lead blocks 25 connected by the surface threads to move closer to each other. At this time, as the first lead block 25 moves horizontally, it will drive the wedge push block 26 to move vertically upward. At this time, the adsorption and fixing mechanism 3 will separate and transport the membrane. The direct vertical upward linear pulling in the prior art is transformed into a more controllable and precise linear pulling by using the wedge push block 26 and the wedge surface of the lifting frame 27 to slide and lift, reducing the risk of the membrane being subjected to instantaneous increase in tension.

[0039] At the same time, two No. 1 filament blocks 25 drive two sets of adsorption and fixing mechanisms 3 to simultaneously separate and transport the film from both ends of the liquid crystal panel. This can avoid the problem of excessively large tilting angle of the film on one side during the pulling process when separating and transporting the film from one side in the existing technology, and reduce the deformation of the film during the separation and transport process.

[0040] When the servo motor 23 drives the adsorption fixing mechanism 3 to separate and transport the film, it also drives the No. 3 wire block 71 to move relative to each other. The movement of the No. 3 wire block 71 and the No. 5 mounting bracket 72 drives the de-adhesion component 73 to perform synchronous and comprehensive treatment on the adhesive layer interface on the surface of the liquid crystal panel, thereby ensuring that the separation fixing mechanism 2 and the adsorption fixing mechanism 3 can stably separate and transport the film.

[0041] The servo motor 23 drives the lead screw 24 to move the first lead block 25 with wedge-shaped pusher 26 horizontally relative to the diaphragm. The wedge-shaped pusher 26 slides in the guide groove of the lifting frame 27, converting the horizontal motion into the vertical lifting of the lifting frame 27, thereby achieving indirect linear tension on the diaphragm. In the separation and fixing mechanism 2, the servo motor 23 drives the lead screw 24 to move the first lead block 25 and the wedge-shaped pusher 26, converting the traditional vertical tension into indirect linear tension by wedge lifting, avoiding a sudden increase in tension. The two sets of adsorption and fixing mechanisms 3 are synchronously driven by the first lead block 25 to separate and transport the diaphragm from both ends, solving the problem of diaphragm warping and deformation caused by unilateral separation. To address the issue of excessive stress on the substrate during membrane removal, which could damage the substrate, the auxiliary mechanism 7 moves synchronously with the adsorption and fixing mechanism 3. The degumming component 73 processes the adhesive interface in real time, improving separation stability. The adsorption and fixing mechanism 3 has a built-in six-dimensional force sensor 8, which enables precise sensing and flexible control of the separation force, ultimately significantly reducing the risk of membrane breakage and improving separation and handling efficiency and accuracy. After the membrane is separated from both ends to the middle by the separation and fixing mechanism 2, the membrane that is still adhered in the middle can be pulled and separated by the three-axis handling mechanism 1 driving the separation and fixing mechanism 2.

[0042] The first suction cup assembly 33 is connected to an external air source through an air tube. The compressed air provided by the air source is delivered to the suction cup through the air tube to realize the adsorption or release action. At the same time, control components such as solenoid valves can be connected in series in the air tube. These components are connected to the control system (such as PLC). The control system controls the opening and closing of the solenoid valve by sending electrical signals, thereby regulating the supply and cutting off of the air source and completing the precise control of the adsorption state of the first suction cup assembly 33.

[0043] Example 2: Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, the side of the placement platform mechanism 4 is equipped with an adjustment mechanism 5 for adjusting the position of the LCD panel. The adjustment mechanism 5 includes a telescopic component 51, and a fixed frame 52 is fixedly connected to the moving end of the telescopic component 51. A limit plate 53 is fixedly connected to the upper part of the fixed frame 52, and an industrial camera 6 is installed on the outside of the limit plate 53. The placement platform mechanism 4 includes a base 41, a second-order wire block 47, and a drive component 410. A third-order mounting bracket 42 is fixedly connected to the upper part of the base 41, and a fourth-order mounting bracket 43 is installed on the upper part of the third-order mounting bracket 42. Multiple sets of second-order suction cup assemblies 44 are fixedly connected to the upper part of the fourth-order mounting bracket 43. Multiple buffer components 45 are fixedly connected to the upper part of the fourth mounting bracket 43. The buffer components 45 are located between two adjacent fourth mounting brackets 43. A support frame 46 is fixedly connected to the upper part of the buffer components 45. A drive component 410 for driving the second screw block 47 to rotate is installed on the surface of the third mounting bracket 42. The second screw block 47 is rotatably connected to the third mounting bracket 42. The second screw block 47 is internally threaded with a second screw rod 48. The bottom of the second screw rod 48 is fixedly connected to the fourth mounting bracket 43. A limit rod 49 is fixedly connected to the bottom of the fourth mounting bracket 43. The limit rod 49 is slidably inserted into the third mounting bracket 42.

[0044] In this embodiment, the liquid crystal panel is placed on the upper part of the placement platform mechanism 4. The telescopic component 51 pulls the fixing frame 52 and the limiting plate 53 to move closer to each other. The flat side of the limiting plate 53 is used to neatly place the liquid crystal panel on the upper part of the placement platform mechanism 4, which facilitates the accurate movement and placement of the separated film and liquid crystal panel. During the process of placing the liquid crystal panel on the second suction cup component 44, the bottom of the liquid crystal panel first contacts the support frame 46. At the same time, the buffer component 45 undergoes telescopic deformation to buffer the impact force when the liquid crystal panel is placed. The liquid crystal panel's own weight is used to keep the buffer component 45 in a compressed state. At this time, the bottom of the liquid crystal panel is in contact with the surface of the second suction cup component 44. After the liquid crystal panel is neatly placed by the adjustment mechanism 5, the bottom of the liquid crystal panel is adsorbed and fixed by the second suction cup component 44.

[0045] Subsequently, the industrial camera 6 acquires image information of the fixed LCD panel on the upper part of the placement platform mechanism 4, and the external industrial control computer calculates the position and size information of the LCD panel and generates control commands.

[0046] Based on the size data of the LCD panel, the position of the first suction cup assembly 33 is adjusted by the second X-axis moving assembly 31 and the second Y-axis moving assembly 32 so that the first suction cup assembly 33 can be adapted to the size of the LCD panel. At the same time, the three-axis conveying mechanism 1 adjusts the position of the adsorption and fixing mechanism 3 according to the control command so that the first suction cup assembly 33 is accurately adsorbed on the surface of the LCD panel film.

[0047] During the separation and handling of the film on the surface of the LCD panel, the six-dimensional force sensor 8 monitors the force on the first suction cup assembly 33 in real time, especially the pressure of the first suction cup assembly 33 on the film. When the pulling force of the first suction cup assembly 33 on the film exceeds the set threshold, the rotation of the servo motor 23 is reduced, thereby reducing the rising speed of the lifting frame 27 driving the adsorption fixing mechanism 3, and thus reducing the pulling force on the film. At the same time, a redundant processing structure is set up. The Z-axis moving assembly 13 drives the separation fixing mechanism 2 to move downward while the lifting frame 27 rises. The difference in the lifting distance is used to finely control the pulling force on the separation and handling of the film. Similarly, the drive assembly 410 drives the second screw block 47 to rotate, and the second screw 48 drives the fourth mounting frame 43 and the third mounting frame 42 to rise and fall, controlling the pulling force on the separation and handling of the film.

[0048] When separating and transporting liquid crystal panels and films without adhesive layer interfaces, the lifting and lowering of the second suction cup assembly 44 and the lifting and lowering of the separation fixing mechanism 2 and the adsorption fixing mechanism 3 driven by the Z-axis moving assembly 13 can improve the efficiency of film separation from liquid crystal panels, thereby improving the efficiency of film transport.

[0049] The telescopic component 51 of the adjustment mechanism 5 drives the limiting plate 53 for centering and positioning. Combined with the visual inspection of the industrial camera 6, it ensures the precise placement of the LCD panel on the placement platform mechanism 4. The buffer component 45 and the second suction cup component 44 of the placement platform mechanism 4 achieve flexible fixation and adsorption of the panel, avoiding damage from rigid contact. The six-dimensional force sensor 8 monitors the adsorption force in real time and controls the servo motor 23, the Z-axis moving component 13 and the drive component 410 in linkage. Through multi-axis collaborative adjustment of the tension threshold, the force control of the film separation process is refined. The redundant lifting design can dynamically adjust the separation strategy for different adhesive layer characteristics, significantly improving the separation efficiency of films without adhesive layers. Finally, a closed-loop control of the entire process from positioning, adsorption to separation is formed, taking into account both accuracy and efficiency.

[0050] The second suction cup assembly 44 is connected to an external air source via an air pipe. Compressed air supplied by the air source is delivered to the suction cup through the air pipe to achieve adsorption or release. At the same time, control components such as solenoid valves can be connected in series in the air pipe. These components are connected to a control system (such as a PLC). The control system controls the opening and closing of the solenoid valve by sending electrical signals, thereby regulating the supply and cutting off of the air source and completing the precise control of the adsorption state of the second suction cup assembly 44.

[0051] Example 3: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the auxiliary mechanism 7 includes a No. 3 screw block 71 and a No. 5 mounting bracket 72. The No. 3 screw block 71 is threadedly connected to the No. 1 screw rod 24. The No. 3 screw block 71 is fixedly connected to the No. 5 mounting bracket 72. A degumming component 73 is fixedly connected to the bottom of the No. 5 mounting bracket 72. The degumming component 73 consists of an ultrasonic vibration module, a laser-induced heating module, and an electrostatic elimination module.

[0052] In this embodiment, the adhesive layer interface is processed by the ultrasonic vibration module, laser-induced heating module, and electrostatic elimination module in the adhesive removal component 73. The ultrasonic vibration module includes a high-frequency piezoelectric transducer for applying high-frequency vibration to the interface between the film and the adhesive layer. The laser-induced heating module uses a near-infrared laser emitter and an optical focusing system to achieve micro-area heating of the adhesive layer. The electrostatic elimination module is equipped with a bipolar ion wind generator for eliminating static electricity on the film and processing the adhesive layer interface between the liquid crystal panel and the film.

[0053] The auxiliary mechanism 7 is connected to the lead screw 24 via the threaded connection of the No. 3 thread block 71, so as to realize the synchronous movement of the degumming component 73 and the separation and fixing mechanism 2. The ultrasonic vibration module, laser-induced heating module and electrostatic elimination module in the degumming component 73 can weaken the van der Waals force between the membrane and the adhesive layer through high-frequency vibration, reduce the viscosity of the adhesive layer through micro-area heating, and eliminate static electricity to prevent secondary adhesion. The synergistic effect of multiple physical fields reduces the adhesion of the adhesive layer. The No. 3 thread block 71 rotates synchronously with the No. 1 lead screw 24, which drives the No. 5 mounting bracket 72 and the degumming component 73 to move, ensuring that the degumming process and the separation action of the adsorption and fixing mechanism 3 are matched in real time, realizing the dynamic pretreatment of the adhesive layer interface. The non-contact degumming process avoids the damage to the membrane caused by traditional mechanical peeling. Combined with the real-time force control of the six-dimensional force sensor 8, the separation reliability and production efficiency are significantly improved.

[0054] Example 4: An automated separation method for a liquid crystal panel film separation and handling system, comprising the following steps:

[0055] S1. Place the LCD panel on the upper part of the placement platform mechanism 4. Push and align the four sides of the LCD panel by adjusting the limiting plate 53 in the adjustment mechanism 5 so that the LCD panel is aligned on the upper part of the placement platform mechanism 4. Then, use the second suction cup assembly 44 to adsorb and fix the bottom of the LCD panel.

[0056] S2. The industrial camera 6 collects image information of the fixed LCD panel on the upper part of the placement platform mechanism 4, and the external industrial control computer calculates the position and size information of the LCD panel and generates control commands.

[0057] S3. The adsorption and fixing mechanism 3 adjusts the position of the first suction cup assembly 33 according to the control command, and at the same time, the three-axis conveying mechanism 1 adjusts the position of the adsorption and fixing mechanism 3 according to the control command, so that the first suction cup assembly 33 is accurately adsorbed on the surface of the liquid crystal panel film.

[0058] S4. The adhesive layer interface between the liquid crystal panel and the film is processed by the auxiliary mechanism 7. At the same time, the separation and fixing mechanism 2 drives the two sets of adsorption and fixing mechanisms 3 to pull and separate the film on the surface of the liquid crystal panel from both ends.

[0059] S5. During the process of separating the film by the separation and fixing mechanism 2 driving the adsorption and fixing mechanism 3, the tension data of the first suction cup assembly 33 is monitored by the six-dimensional force sensor 8. The speed at which the separation and fixing mechanism 2 drives the adsorption and fixing mechanism 3 to rise is automatically adjusted according to the tension data to avoid damage to the LCD panel and film caused by excessive tension.

[0060] The working principle and usage of this device are as follows: The LCD panel is placed on the upper part of the placement platform mechanism 4. The telescopic component 51 pulls the fixing frame 52 and the limiting plate 53 to move closer to each other. The flat side of the limiting plate 53 is used to neatly place the LCD panel on the upper part of the placement platform mechanism 4, which facilitates the accurate movement and placement of the separated film and LCD panel.

[0061] Subsequently, the industrial camera 6 acquires image information of the fixed LCD panel on the upper part of the placement platform mechanism 4, and the external industrial control computer calculates the position and size information of the LCD panel and generates control commands.

[0062] Based on the size data of the LCD panel, the position of the first suction cup assembly 33 is adjusted by the second X-axis moving assembly 31 and the second Y-axis moving assembly 32 so that the first suction cup assembly 33 can be adapted to the size of the LCD panel. At the same time, the three-axis conveying mechanism 1 adjusts the position of the adsorption and fixing mechanism 3 according to the control command so that the first suction cup assembly 33 is accurately adsorbed on the surface of the LCD panel film.

[0063] The auxiliary mechanism 7 processes the adhesive layer interface between the liquid crystal panel and the film, while the separation and fixing mechanism 2 drives two sets of adsorption and fixing mechanisms 3 to pull and separate the film on the surface of the liquid crystal panel from both ends in a synchronized manner.

[0064] During the process of separating the film by the separation and fixing mechanism 2 driving the adsorption and fixing mechanism 3, the tension data of the first suction cup assembly 33 is monitored by the six-dimensional force sensor 8. The speed at which the separation and fixing mechanism 2 drives the adsorption and fixing mechanism 3 to rise is automatically adjusted according to the tension data. Finally, the film is separated and transported from the surface of the liquid crystal panel. After the film is separated and transported, it is moved to the set position by the three-axis transport mechanism 1.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
