Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a display panel cutting device. Background Technology

[0002] The display panel is the main component of a display. In the manufacturing process of a display panel, a large display panel motherboard is usually cut according to the target product size to form multiple independent display units. The display panel includes a TFT (Thin Film Transistor) substrate and a CF (Color Filter) substrate that are bonded together.

[0003] The existing method for cutting display panel motherboards involves simultaneously and cross-cutting the TFT display panel and the CF display panel, with unit separation achieved through vertical cutting. During the cutting process, the display panel must be conveyed with the CF display panel facing downwards. This cutting method can cause the display panel to break apart during subsequent conveying; moreover, conveying the CF display panel downwards can cause the surface of the CF display panel to directly contact the rollers. Hard particles on the rollers can scratch the surface of the CF display panel under pressure, potentially causing micro-short circuits or edge light leakage, thus reducing product yield. Utility Model Content

[0004] The purpose of this invention is to provide a display panel cutting device that can reduce the risk of scratches on loose wafers and CF substrates and improve product yield.

[0005] This utility model provides a display panel cutting device. The display panel includes a TFT substrate and a CF substrate bonded together. The display panel cutting device includes a cross-cutting mechanism, a flipping and conveying mechanism, a first line cutting mechanism, a first slitting mechanism, a second line cutting mechanism, and a second slitting mechanism. The cross-cutting mechanism is used to cut the TFT substrate along a first direction and a second direction that are perpendicular to each other when the TFT substrate of the display panel is placed facing upwards, forming a grid-like segmentation. The flipping and conveying mechanism is used to flip the grid-like segmented display panel to a state where the CF substrate faces upwards and convey it sequentially. The first line cutting mechanism is used to cut a first linear slit on the CF substrate along a first direction to form a first linear slit. The first slitting mechanism is used to slit the display panel into strips along the first linear slit. The second line cutting mechanism is used to cut a second linear slit on the CF substrate of the strips along a second direction to form a second linear slit. The second slitting mechanism is used to slit the strips into independent display units along the second linear slit.

[0006] Compared with existing technologies, the display panel cutting apparatus provided by this utility model first divides the TFT substrate of the display panel into a grid pattern using a cross-cutting mechanism. Then, a flipping and conveying mechanism flips the gridded display panel to a CF substrate-facing position and sequentially conveys it to a first wire cutting mechanism. The first wire cutting mechanism cuts the CF substrate along a first direction, forming a first linear slit on the CF substrate. Then, a first slitting mechanism slits the display panel into strips along the first linear slit. A second wire cutting mechanism cuts the CF substrate of the strips along a second direction, forming a second linear slit. Then, the second slitting mechanism slids the strips into independent display units along the second linear slit. This display panel cutting apparatus, by first dividing the TFT substrate into a grid pattern and then flipping the display panel to a CF substrate-facing position and conveying it sequentially, cuts the CF substrate in two steps, avoiding premature breakage during conveying. Furthermore, the CF substrate is continuously conveyed upwards in subsequent processes, effectively reducing surface scratches on the CF substrate and improving product yield.

[0021] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In the manufacturing process of display panels, a large display panel motherboard is typically cut to the dimensions of the target product, forming multiple independent display units suitable for that product. The display panel consists of a TFT substrate and a CF substrate bonded together. The TFT substrate has millions of tiny thin-film transistors fabricated on it, each corresponding to a pixel. The TFT acts like a switch, precisely controlling the voltage applied to the liquid crystal material, thereby controlling the amount of light transmitted to that pixel. The CF substrate has red, green, and blue color filter units that precisely correspond to the pixel matrix of the TFT substrate. These filters are responsible for converting white light emitted from the backlight into colored light. The CF substrate includes an RGB color filter layer, a black matrix (used to separate pixels, prevent color crosstalk, and improve contrast), and a common electrode (i.e., an ITO layer) covering the filters. The common electrode is a transparent, conductive ceramic film with good conductivity and light transmittance, but its hardness and wear resistance are relatively limited; it is brittle and its surface is relatively easy to scratch by hard objects.

[0024] In the process of cutting the motherboard of the display panel into independent display units of the target product, the TFT substrate and CF substrate are all cross-cut, and the unit separation is carried out by vertical cutting. This cutting method can cause the display panel to break apart during subsequent transportation. Moreover, during the cutting process, the display panel is mainly transported with the CF substrate facing down. When the CF substrate is placed face down during transportation, the common electrode is in direct and continuous contact and friction with the rollers, guide rails or conveyor belt of the transportation mechanism, which may cause fine scratches on the surface of the common electrode, resulting in electrical short circuit risk or display defects, and may even affect the uniformity of light transmission.

[0025] This embodiment provides a display panel cutting device. First, the display panel is placed with the CF substrate facing down and the TFT substrate is cross-cut. Then, the display panel is flipped to the CF substrate facing up, and the CF substrate is sequentially subjected to a first wire cut, a first split, a second wire cut, and a second split. This ensures that the display panel forms an independent display unit only after the last split, which can reduce the occurrence of loose wafers. During the cutting and splitting process of the CF substrate, the CF substrate of the display panel is always placed facing up, which reduces the probability of scratches on the CF substrate affecting product yield.

[0026] Figure 1 The image shown is a plan view of the display panel cutting device. Figure 1 As shown, the display panel cutting device includes a cross-cutting mechanism 1, a flipping conveyor mechanism 2, a first wire cutting mechanism 3, a first slitting mechanism 4, a second wire cutting mechanism 5, and a second slitting mechanism 6. These mechanisms are arranged sequentially along the extension direction of the production line. The flipping conveyor mechanism 2 extends from the rear of the cross-cutting mechanism 1 to the end of the display panel cutting device. After the display panel undergoes grid-like cutting of the TFT substrate on the positioning platform of the cross-cutting mechanism 1, it is conveyed to the flipping conveyor mechanism 2. The flipping conveyor mechanism 2 flips the display panel... The display panel is sequentially conveyed to the first wire cutting mechanism 3, where the CF substrate is wire-cut along the first direction on the positioning platform of the first wire cutting mechanism 3. After the first wire cutting is completed, the display panel is conveyed to the first slitting mechanism 4, where the first slitting mechanism 4 slits the display panel along the first direction, forming multiple strip plates. The strip plates are then sequentially conveyed to the second wire cutting mechanism 5, where the CF substrate of the strip plates is wire-cut along the second direction on the positioning platform of the second wire cutting mechanism 5. After the second wire cutting is completed, the strip plates are conveyed to the second slitting mechanism 6, where the second slitting mechanism 6 slits the display panel along the second direction, resulting in independent display units.

[0027] A cross-cutting mechanism 1 is used to cut the TFT substrate along a first and a second direction, which are perpendicular to each other, to form a grid-like segmentation when the TFT substrate of the display panel is placed facing upwards. A flipping and conveying mechanism 2 is used to flip the grid-segmented display panel to a CF substrate-facing-up state and convey it sequentially. A first wire cutting mechanism 3 is used to cut a first linear slit along the first direction on the CF substrate. A first slitting mechanism 4 is used to slit the display panel into strips along the first linear slit. A second wire cutting mechanism 5 is used to cut a second linear slit along the second direction on the CF substrate of the strip to form a second linear slit. A second slitting mechanism 6 is used to slit the strip into individual display units along the second linear slit.

[0028] When cutting a display panel, this display panel cutting device first cuts the TFT substrate in a grid pattern, then flips the display panel so that the CF substrate faces upward and conveys it sequentially. This process divides the CF substrate into two steps for cutting and separating, avoiding premature separation and breakage during the conveying process. At the same time, the CF substrate is always conveyed upward in subsequent processes, which effectively reduces scratches on the surface of the CF substrate and improves the product yield.

[0029] In one embodiment, the first wire cutting mechanism 3 and the second wire cutting mechanism 5 have the same structure and working principle as the cross cutting mechanism 1, both used for wire cutting. The cross cutting mechanism 1 is positioned at the front and is used to perform wire cutting along the first and second directions of the TFT substrate sequentially. The first wire cutting mechanism 3 and the second wire cutting mechanism 5 are sequentially positioned at the rear of the cross cutting mechanism 1 to cut the CF substrate in two steps: the first wire cutting mechanism 3 performs wire cutting along the first direction, and the second wire cutting mechanism 5 performs wire cutting along the second direction. Both the first wire cutting mechanism 3 and the second wire cutting mechanism 5 include a positioning platform and a cutting head. The positioning platform is used to fix the display panel, and the cutting head is configured as a dual-mode cutting head that can switch between guide wheels and lasers, selectively performing mechanical wheel cutting or laser cutting. The specific structure and working principle of the cross cutting mechanism 1, the first wire cutting mechanism 3, and the second wire cutting mechanism 5 can be designed with reference to existing technology, which is not the focus of improvement in this embodiment and will not be described in detail here.

[0030] In one embodiment, the flipping and conveying mechanism 2 includes a flipping platform and an infrared sensor. The flipping platform is used to flip the display panel 180° and convey the flipped display panel to the first wire cutting mechanism 3. The infrared sensor is used to detect the flipping state of the display panel in real time. The specific structure and working principle of the flipping platform can be referred to the existing technology design, which is not the focus of the improvement of this embodiment, and will not be described in detail here.

[0031] The TFT substrate on one side of the display panel has already been meshed and cut. During the first wire cutting, the CF substrate is cut along the slit in the first direction of the TFT substrate. After the first wire cutting, the CF substrate is then cut by the first cutting mechanism 4, which cuts along the slit in the first direction of the TFT substrate and the CF substrate, thus dividing the display panel into strips. During the second wire cutting, the CF substrate is cut along the slit in the second direction of the TFT substrate. After the second wire cutting, the CF substrate is then cut by the second cutting mechanism 6 into individual display units.

[0032] The display panel cutting device provided in this embodiment has a different cutting method than the vertical cutting method in the prior art. Therefore, the first cutting mechanism 4 and the second cutting mechanism 6 are the key improvements of this embodiment.

[0033] The first breaking mechanism 4 and the second breaking mechanism 6 have the same structure and working principle. Figure 2 The diagram shown is a schematic diagram of the first breaking mechanism 4 and the second breaking mechanism 6. Figure 2 As shown, when the first splitting mechanism 4 and the second splitting mechanism 6 are splitting, the first splitting mechanism 4 first splits the part of the display panel located on one side of the cut at the outermost edge of the display panel. The part of the display panel located on one side of the cut at the outermost edge is pushed onto the splitting table 72, while the remaining part is adsorbed and fixed on the support table 71. The splitting table 72 drives the part of the display panel to rotate around the cut, thereby separating the part of the display panel from the remaining part of the display panel.

[0034] Figure 3 The image shown is a front view of the first splitting mechanism 4 and the second splitting mechanism 6. Figure 4 The image shown is a top view of the first splitting mechanism 4 and the second splitting mechanism 6. Figure 5 The image shows a side view of the first splitting mechanism 4 and the second splitting mechanism 6, as shown. Figures 3-5 As shown, both the first splitting mechanism 4 and the second splitting mechanism 6 include a support platform 71 and a splitting table 72. The support platform 71 has a support surface 711 for adsorbing the display panel and can transport the display panel. The splitting table 72 can move to dock with the support platform 71, receive and adsorb the portion of the display panel located on one side of the slit, and rotate around the slit to achieve splitting. The splitting table 72 rotates around the slit with a rotation angle ≤5°, applying a pure bending moment load to the display panel, so that the bottom end of the slit bears a tensile stress dominated by tension, avoiding the shear stress generated by traditional vertical splitting which easily induces large-scale cracks, and reducing the probability of edge chipping of the CF substrate. The support platform 71 and the splitting table 72 adsorb the display panel synchronously, and there is no relative displacement between the display panel and the platform throughout the splitting process, eliminating surface indentations caused by traditional mechanical clamping.

[0035] For example, the adsorption surfaces of the support surface 711 and the breaking stage 72 are both adsorbed by vacuum adsorption. The working principle of vacuum adsorption is existing technology and will not be described in detail here.

[0036] In one embodiment, the first splitting mechanism 4 and the second splitting mechanism 6 further include a conveying component 73 disposed on the support platform 71, used to lift and push the display panel to push a portion of the display panel to the splitting table 72. After the support surface 711 releases its suction force on the display panel, the conveying component 73 moves upward to first lift the display panel, and then pushes the display panel closer to the splitting table 72, pushing a portion of the display panel on one side of the outermost slit to the splitting table 72, so that the slit is located between the support surface 711 and the splitting table 72, thereby enabling the display panel to be split from the slit when the splitting table 72 rotates.

[0037] In one embodiment, such as Figure 4 As shown, the conveying assembly 73 includes at least two opposing pushers 731. The pushers 731 are configured to move vertically and horizontally. When raised, they separate the display panel from the support surface 711 and push the display panel towards the splitting table 72. When lowered, they retract below the support surface 711, allowing the display panel to be magnetically attached and fixed to the support surface 711. The display panel is first lifted and then pushed to avoid friction between the display panel and the support surface 711. The horizontal movement of the conveying mechanism reduces inertial jitter compared to robotic gripping. The at least two opposing pushers 731 apply symmetrical force to ensure the stability of the display panel conveying.

[0038] For example, the support surface 711 includes multiple support plates, which are spaced apart along the conveying direction perpendicular to the display panel, and a preset gap is left between adjacent support plates. The push bar 731 passes through the preset gap when it is raised and lowered. With this arrangement, the push bar 731 can also be set in the middle position of the support platform 71. When the display panel is conveyed, the middle position and both sides of the display panel are subjected to the pushing force of the push bar 731, which further ensures the stability of the conveying.

[0039] The lifting and horizontal movement of push bar 731 can be driven by electric push rod or linear motor, and realized by corresponding transmission and connecting parts, which will not be described in detail here.

[0040] Figure 6 The diagram shows the structure of the breaking stage 72 and the drive assembly 74. Figure 6As shown, in one embodiment, the first splitting mechanism 4 and the second splitting mechanism 6 further include a drive assembly 74, including a first drive member 741 and a rotating shaft 742. The first drive member 741 drives the splitting table 72 to rotate around the cutting slit via the rotating shaft 742. The splitting table 72 includes a base and a rotating plate rotatably disposed in the middle of the base. The bottom of the rotating plate is connected to the rotating shaft 742, and the axis of the rotating shaft 742 is perpendicular to the extension direction of the rotating plate. The first drive member 741 is a motor, and the main shaft axis of the motor is parallel to the pushing direction of the display panel. The main shaft of the motor is connected to the rotating shaft 742 through a vertically meshing helical gear set to realize the rotation of the splitting table 72 around the cutting slit.

[0041] In one embodiment, the driving assembly 74 further includes a slide 743, a first guide rail 744, and a second driving member 745. The slide 743 fixes the first driving member 741. The first guide rail 744 is slidably connected to the slide 743. The second driving member 745 drives the slide 743 to move along the first guide rail 744 to drive the chipping table 72 to translate, so that when the first driving member 741 drives the chipping table 72 to rotate, the second driving member 745 synchronously drives the chipping table 72 to move away from the support platform 71. The first driving member 741 is fixed to the top of the slide 743, and the bottom of the slide 743 is slidably mounted on the first guide rail 744 through a slider or other structure. When the first driving member 741 drives the chipping table 72 to rotate, the second driving member 745 synchronously drives the chipping table 72 to move away from the support platform 71, thus preventing the display panels on both sides of the slit from being squeezed and causing the CF substrate to chip when the chipping table 72 drives the display panel to rotate around the slit, thereby improving the product yield.

[0042] For example, the second drive unit 745 includes a motor, a lead screw, and a nut seat. The motor is connected to the lead screw, the lead screw is connected to the nut seat, and the nut seat is connected to the slider. The motor drives the lead screw to rotate, and the lead screw drives the slider to move along the first guide rail 744 through the nut seat.

[0043] In one embodiment, the first breaking mechanism 4 and the second breaking mechanism 6 further include a pressing component 75 located above the support platform 71 and the breaking platform 72. The pressing component 75 is configured to move to a side close to the breaking platform 72 or the support platform 71 to press down and remove the residual material after breaking. After the breaking platform 72 rotates and breaks part of the display panel, the pressing component 75 can move to a side close to the breaking platform 72 to press down and break the residual material remaining on one side of the part of the display panel, separating it from the display panel; or, it can move to a side close to the support platform 71 to press down and break the residual material remaining on the other side of the display panel, separating it from the display panel.

[0044] For example, the pressing component 75 includes a wedge-shaped pressing knife. After the pressing component 75 moves to a set position near the support table 71 or the breaking table 72, the wedge-shaped pressing knife descends and contacts the residual material, which can separate the residual material from the display panel. After the residual material is removed, it falls directly to the ground between the support table 71 and the breaking table 72 or into the residual material collection box.

[0045] In one embodiment, the first splitting mechanism 4 and the second splitting mechanism 6 further include a alignment camera 76 located above the support platform 71 and the splitting table 72, for detecting the position of the display panel. The alignment camera 76 detects the position of the display panel in real time to ensure that the display panel is in the set position on the support platform 71 and the splitting table 72, ensuring that the cut is in the appropriate position each time the splitting table 72 rotates to split the display panel, reducing damage to the display panel caused by inaccurate cut position during splitting.

[0046] For example, the alignment camera 76 is communicatively connected to the controller of the display panel cutting device. The alignment camera 76 can transmit the photograph of the display panel to the controller. The controller stores a standard photograph of the kerf in the accurate position. The controller compares the received photograph with the pre-stored standard photograph and determines whether the position of the display panel is accurate. If accurate, the controller controls the first drive member 741 to drive the splitting table 72 to rotate. If inaccurate, the controller controls the conveying component 73 to adjust the position of the display panel. Once the position of the display panel is determined to be accurate, the controller controls the first drive member 741 to drive the splitting table 72 to rotate.

[0047] In one embodiment, the first splitting mechanism 4 and the second splitting mechanism 6 further include a support frame 77, which is mounted above the splitting table 72. A positioning camera 76 is fixed to the support frame 77, and a pressing component 75 is slidably mounted on the support frame 77. The support frame 77 drives the positioning camera 76 and the pressing component 75 to move closer to or further away from the support table 71. By setting the support frame 77 to support the positioning camera 76 and the pressing component 75, and to drive the positioning camera 76 and the pressing component 75 to move closer to or further away from the support table 71, the position detection of the display panel and the removal of residual material from different positions by the pressing component 75 are achieved.

[0048] For example, the movement of the support frame 77 is driven by a linear drive such as a linear motor, and a second guide rail is provided to guide the movement of the support frame 77, so as to ensure the accuracy of the position when the support frame 77 drives the alignment camera 76 and the pressing component 75 to move.

[0049] In one embodiment, the first splitting mechanism 4 and the second splitting mechanism 6 further include a cleaning component 78, which is slidably mounted on the support platform 71 and is used to clean the support surface 711. After each motherboard of a display panel is split, the support surface 711 is cleaned by the cleaning component 78 to prevent residues on the support surface 711 from damaging the next display panel.

[0050] For example, the cleaning assembly 78 includes a cleaning drive and a cleaning brush, the cleaning brush spanning the support platform 71, and the cleaning drive drives the cleaning brush to move along the pushing direction of the display panel to ensure efficient cleaning of the support surface 711.

[0051] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
