Description

Technical Field

[0001] The invention relates to the field of LCD production equipment, and in particular to a film tearing system. Background Art

[0002] In the production process of LCD panels, film tearing is a key step to remove the protective film on the surface of the panel.

[0003] Currently, among the existing film tearing methods, the panel is inverted to tear the film. However, the inverted panel requires additional design of a gripping mechanism, which is costly, and the back of the gripping panel is usually designed to be combined with important structures of other panels (such as liquid crystal layer, circuit layer), and the gripping action and mechanical contact may affect this part.

[0004] In order to improve product quality, the film tearing system is changed to tearing the film from the front of the panel, that is, when the panel is placed with the front side facing up, the protective film on the panel is torn off using an automatic film tearing structure. In this working mode, since the protective film is torn off upwards, there is firstly a risk of dust falling on the panel. Secondly, the movement path of the film tearing structure is different from the movement path of tearing off the protective film downwards. It has an initial lift and a movement path that moves in a single direction. For some types of panels, the adhesion between the protective film and the panel surface is strong. Compared with the downward movement path, in the process of clamping the Mylar to drive the tearing of the protective film, the upward movement path is more difficult to stably reproduce the tearing action of the protective film in large-scale processing. Therefore, for panels with important structures on the back, there is an urgent need for a film tearing system that can tear the film from the front of the panel and can also achieve dust-free, efficient and convenient operation.

[0028] See also Figures 1 to 3 , is a film tearing system in an embodiment of the present invention, which is used to tear off the protective film 11 on the LCD panel 10. The film tearing system includes a three-dimensional motion mechanism, a horizontal plane rotation mechanism and a film tearing mechanism.

[0029] Wherein: the three-dimensional motion mechanism is connected with the horizontal plane rotation mechanism, and the horizontal plane rotation mechanism is connected with the film tearing mechanism, so that the three-dimensional motion mechanism can drive the horizontal plane rotation mechanism and the film tearing mechanism to move synchronously in multiple directions, and the horizontal plane rotation mechanism drives the film tearing mechanism to rotate at all angles, so as to drive the position adjustment of the film tearing mechanism in three-dimensional space through the three-dimensional motion mechanism and the horizontal plane rotation mechanism, so as to facilitate the positioning of the film tearing mechanism at the position where the protective film 11 is located on the LCD panel 10, and to drive the film tearing mechanism to avoid when other components move. Specifically, the three-dimensional motion mechanism includes an X-axis motion slide rail, a Y-axis motion slide rail and a Z-axis motion slide rail, and each motion slide rail is in contact with the movement of other axes. The slide rails are slidably connected to achieve multi-axis movement, that is, the X-axis motion slide rail is slidably connected to the Z-axis motion slide rail through a connecting block, the Y-axis motion slide rail is installed on the X-axis motion slide rail, and the horizontal plane rotation mechanism is installed on the Y-axis motion slide rail, so that the Z-axis motion slide rail can be used to drive the X-axis motion slide rail and the Y-axis motion slide rail to perform lifting movement along the Z-axis direction, the X-axis motion slide rail can be used to drive the Y-axis motion slide rail to perform translational movement along the X-axis direction, and the Y-axis motion slide rail can be used to drive the horizontal plane rotation mechanism and the film tearing mechanism to perform translational movement along the Y-axis direction. It can be understood that the Y-axis direction is perpendicular to the X-axis direction, and the X-axis direction and the Y-axis direction are both parallel to the horizontal plane, and the Z-axis direction is perpendicular to the horizontal plane.

[0030] It should be noted that the drive of the X-axis motion slide, the Y-axis motion slide and the Z-axis motion slide can all be driven by a motor, a hydraulic cylinder or a pneumatic cylinder, and the multi-axis motion slide belongs to the existing technology, so it will not be described here.

[0031] In this embodiment, the horizontal plane rotation mechanism includes a mounting base and a rotating motor. The mounting base and the rotating motor are both connected to the slider of the Y-axis motion rail in the three-dimensional motion mechanism. The driving shaft of the rotating motor is connected to the center of the mounting base. A receiving groove is opened at the bottom of the mounting base. The rotating motor is located in the receiving groove to facilitate the installation of the rotating motor. An adapter plate is provided on the mounting base, and a connecting structure is provided on the adapter plate. The film tearing mechanism is detachably connected to the adapter plate through the connecting structure so that it can be removed when the film tearing mechanism needs maintenance.

[0032] It should be noted that, in the present embodiment, the connecting structure is a threaded structure, and the film tearing mechanism is installed on the adapter plate by means of screw installation realized by the threaded structure. In other embodiments, the connecting structure includes a quick-release plate and a quick-release plate base, the quick-release plate base is connected to the adapter plate, the quick-release plate is connected to the film tearing mechanism, and the quick-release plate is clamped with the quick-release plate base, so that the film tearing mechanism can be quickly disassembled and assembled through the structural cooperation between the quick-release plate and the quick-release plate base. Specifically, the quick-release plate has an elastic structure so that the quick-release plate can be quickly clamped in the quick-release plate base.

[0033] In this embodiment, the film tearing mechanism includes a first clamping foot 21, a second clamping foot 22 and a driving assembly. The first clamping foot 21 and the second clamping foot 22 are respectively located on opposite sides of the protective film 11, and the first clamping foot 21 contacts the top of the protective film 11, and the second clamping foot 22 contacts the bottom of the protective film 11. The first clamping foot 21 and the second clamping foot 22 are both connected to the driving assembly, and the driving assembly is used to drive the first clamping foot 21 and the second clamping foot 22 to move closer to or away from each other to clamp or loosen the protective film 11.

[0034] In this embodiment, an approach angle is provided on the second clamping foot 22, and the approach angle is a multi-layer structure. The interior of the second clamping foot 22 is hollow and is equipped with an injection channel 24. One end of the injection channel 24 is connected to the outlet of the multi-layer structure, and the other end of the injection channel 24 is connected to a ventilation component, which is used to inject air into the injection channel 24. A control valve is provided on the injection channel 24 so that the flow state of the injection channel 24 can be controlled by the control valve. It should be noted that the ventilation component is a prior art and will not be described herein.

[0035] In this embodiment, the multilayer structure includes a first access layer 231 and a second access layer 232, the first access layer 231 is located below the second access layer 232, the first access layer 231 is connected to the second access layer 232 to form a two-level stepped structure, the first access layer 231 and the second access layer 232 are both hollow inside to form a corresponding installation space, the installation space of the first access layer 231 and the second access layer 232 are both connected to the inside of the second clamping foot, and the installation space of the first access layer 231 and the second access layer 232 are respectively matched with an injection channel 24, that is, the injection channel 24 extends to the first access layer 23 1 or the outlet of the second approach layer 232. It should be noted that the opening of the gas injection channel 24 is gradually narrowed from the driving component toward the first approach layer 231 or the second approach layer 232, so that the opening of the gas injection channel 24 toward one end of the protective film is consistent with the outlet size of the first approach layer 231 or the second approach layer 232. Through the design of narrowing the channel opening, the Laval effect of the gas when it is sprayed out of the outlet of the first approach layer 231 or the second approach layer 232 can be enhanced to enhance the initial velocity or initial kinetic energy of the gas, which is conducive to injecting air into the bonding interface of the film layer with strong viscosity to form the desired bubble or purge effect.

[0036] In this embodiment, the first access layer 231 and the second access layer 232 are both triangular pyramid structures. The angle of the first access layer 231 relative to the horizontal plane is smaller than the angle of the second access layer 232 relative to the horizontal plane. The first access layer 231 contacts the bottom of the protective film 11 before the second access layer 232. It should be noted that the angle of the first access layer 231 relative to the horizontal plane is 5°~10°, and the angle of the second access layer 232 relative to the horizontal plane is 20°~30°. Angles that are too large or too small will affect the success rate of the first access layer 231 and the second access layer 232 entering the boundary between the protective film 11 and the LCD panel 10 respectively.

[0037] In this embodiment, the second clamping foot 22 is in the shape of a long strip with a wider end and a narrower end, or can be regarded as a pointed chopstick shape, and the first approach layer 231 and the second approach layer 232 are both located at the narrower end of the second clamping foot 22. In order to facilitate the first approach layer 231 to be smoothly inserted into the boundary between the protective film 11 and the LCD panel 10, the tip of the first approach layer 231 is generally designed to be narrower, and the angle of the first approach layer 231 is smaller. Since the first clamping foot 21 does not need to be inserted into the boundary between the protective film 11 and the LCD panel 10, it is not necessary to set an approach angle, and a thicker end can be used, or a flat, planar end can be used so that it can contact the surface of the film.

[0038] It should be noted that the purpose of injecting air into the first approach layer 231 and the second approach layer 232 is different. During the film tearing process, the first approach layer 231 will first contact the bottom of the protective film 11. The first approach layer 231 is set at a narrower place on the approach angle, that is, closer to the tip of the approach angle (or it can be said that the first approach layer 231 is the most forward tip of the second clamping foot 22). The purpose of injecting air into the first approach layer 231 is to enable a certain amount of tiny bubbles to be injected into the deep interface of the boundary between the protective film 11 and the LCD panel 10, which is conducive to the subsequent film separation, reduces the damage caused by the separation, and improves the success rate of separation; and the second approach layer 232 follows the movement of the second clamping foot 22 and then contacts the protective film 11. At this time, the edge of the protective film 11 has been affected by the first approach layer 231 and has been lifted up. The second approach layer 232 contacts the protective film 11 to further expand the degree of separation of the film, so as to completely separate the film layer, and the second approach layer 232 continuously outputs a large flow of air to clean the space between the protective film 11 and the LCD panel 10 to prevent dust. The first proximity layer 231 and the second proximity layer 232 can work simultaneously, except that one delivers gas at the deep interface of the boundary (ie, a deeper position of the boundary), and the other delivers gas at the rear.

[0039] It should be noted that the first approach layer 231 is used to first contact the boundary between the film and other layers, insert into the gap at a relatively fine angle, and use a high-speed, low-volume gas delivery method to deliver pulse gas into the gap. The gas forms a number of bubbles in the boundary. Under the action of the bubbles, the contact angle between the film layer and the LCD panel 10 is increased, which significantly improves the separation effect of subsequent film layers and avoids the problems of wrinkles, fractures, and hysteresis caused by discontinuous separation of the film layers. This not only improves the separation efficiency and success rate, but also avoids accidental damage to other layers. The second approach layer 232 subsequently contacts the edge of the protective film 11 as the second clamping foot 22 moves, and is used to further separate the protective film 11. At the same time, it outputs low-speed, high-volume gas, which is used to accelerate the separation of the film layers on the one hand, and can significantly prevent dust from falling into the interface after the film is torn off on the other hand, thereby ensuring the cleanliness of the material.

[0040] In a specific embodiment, the film tearing method implemented by the film tearing system includes the following steps:

[0041] S1, placing the LCD panel 10 on the loading platform, ensuring that one side of the protective film 11 to be torn off is in an empty space;

[0042] S2, the three-dimensional motion mechanism drives the film tearing mechanism to approach the side of the protective film 11 on the LCD panel 10 that is away from the air, and the film tearing mechanism drives the first clamping foot 21 and the second clamping foot 22 to approach the corresponding edge of the protective film 11;

[0043] S3, the first clamping foot 21 contacts the upper side of the protective film 11, and the second clamping foot 22 contacts the boundary between the protective film 11 and the LCD panel 10 through the approach angle, and contacts the lower side of the protective film 11;

[0044] S4, the first approach layer 231 of the approach angle first contacts and enters the boundary between the protective film 11 and the LCD panel 10, and at the same time, the control valve of the first approach layer 231 is opened, and the pre-compressed gas (which may be clean air) in the corresponding gas injection channel 24 is sent into the interface of the boundary in a high-speed and low-volume manner;

[0045] S5, the second approach layer 232 of the approach angle then contacts the edge of the boundary, and at the same time the control valve of the second approach layer 232 is opened, and the continuously delivered gas in the corresponding gas injection channel 24 is sent into the interface of the boundary in a uniform and large amount;

[0046] S6. While the second approach layer 232 contacts the boundary edge, the first approach layer 231 delivers a low amount of air to the deep interface in a manner of contacting the deep interface of the boundary, so that tiny bubbles exist in the deep interface;

[0047] S7 , the first approach layer 231 and the second approach layer 232 work back and forth under the movement of the second clamping foot 22 , so that the protective film 11 is finally torn off.

[0048] The volume of tiny bubbles is calculated as follows:

[0049]

[0050] Among them, σ(α) is the cutting plane expression related to the maximum contact angle α of the bubble, where the maximum contact angle of the bubble is related to the viscosity p of the film, that is, α=f(p). For films with higher viscosity p, the higher the value of the maximum contact angle α, the better. The specific relationship can be obtained from experiments, r is the radial distance in the spherical coordinate system, Φ is the polar angle, θ is the azimuth angle, and the component (a, b, c) from any point (x, y, z) on the irregular ellipsoidal bubble to the coordinate origin.

[0051] It should be noted that after obtaining the volume of the microbubbles, the single injection air volume can be obtained. Based on the air volume and the opening size of the selected first approach layer, various parameters of the jet can be calculated. Specifically, the density of the injected gas is known. For example, if clean air is used, the density under standard conditions is generally 1.29 kg / m 3 The mass of injected air can be calculated based on the volume density. In fact, the injection amount can also be directly measured by the injection volume. A micro air flow meter can be used to control the volume of injected gas. The current automated micro injection equipment has mature experience.

[0052] In the specific implementation, the three-dimensional motion mechanism is connected with the horizontal plane rotation mechanism, and the horizontal plane rotation mechanism is connected with the film tearing mechanism. The first clamping foot 21 in the film tearing mechanism is used to contact the upper part of the protective film 11 on the LCD panel 10, and then the second clamping foot 22 is used to contact the lower part of the protective film 11. Then, the approach angle on the second clamping foot 22 is designed to be a multi-layer structure, and air is injected into the gas injection channel 24. The gas from the gas injection channel 24 is passed into the boundary between the protective film 11 and the LCD panel 10 through the outlet of the multi-layer structure, so that tiny bubbles exist deep in the boundary between the protective film 11 and the LCD panel 10, so as to reduce the destructive effect of the strong adhesion of the protective film 11 on other layers during the film tearing process, and it is also beneficial to improve the smoothness and success rate of film tearing, and it is also beneficial to prevent dust from entering the boundary between the protective film 11 and the LCD panel 10.

[0053] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the film tearing system of the present application has only the above-mentioned implementation process. On the contrary, as long as the film tearing system of the present application can be implemented, it can be included in the feasible implementation plan of the present application.
