[0057] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0059] Unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0060] As used herein, “parallel” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°.

[0061] In related technologies, after the display motherboard is packaged, it is cut to obtain multiple display panels. Figure 1 This is a schematic diagram of the planar structure of the uncut display motherboard 2 in some embodiments. For example... Figure 1As shown, the display motherboard 2 includes a product area and a cutting area surrounding the product area. A cutting groove is provided between the product area and the cutting area, and the display motherboard 2 is cut along the cutting groove. The product area, after cutting, becomes the desired display panel 21. Each display panel 21 has a display area, and a ring-shaped sealing adhesive is provided around the display area to seal the liquid crystal layer of the display panel. The cutting area is the part to be discarded after cutting; in this embodiment, it is referred to as the redundant panel 22. Figure 2 These are schematic diagrams illustrating the process of cutting the display motherboard 2 in some embodiments, wherein, Figure 2 (a) and (b) are side views from different angles during the cutting process of the display motherboard 2. Figure 2 As shown, in some embodiments, a mechanical cutting wheel 1 can be used to cut the display motherboard 2. When cutting the display motherboard 2 using the cutting wheel 1, a certain pressure perpendicular to the display motherboard 2 needs to be applied to the cutting wheel 1. Under the pressure, the cutting wheel 1 cuts downwards into the display motherboard 2, causing vertical cracks to appear in the display motherboard 2, until the entire display motherboard 2 is cut open. While the cutting wheel 1 creates vertical cracks 3 in the display motherboard 2, it also generates small cracks in the horizontal direction, for example, the width of the horizontal cracks 4 is less than 10 μm. Figure 3 This is a planar structural diagram of the cut display motherboard 2.

[0062] Figure 3 The display panel 21 and redundant panel 22 in the cut display motherboard 2 are no longer a whole, but have not yet been separated.

[0063] After the display motherboard 2 is cut, the cut display motherboard 2 is conveyed to the set position by the conveyor belt 5, and then the display panel 21 is picked up by the picking device 6. Figure 4A This is a schematic diagram of the process of transmitting data to the display panel 21 in some embodiments. Figure 4B These are schematic diagrams illustrating the process of picking up the display panel 21 in some embodiments. For example... Figure 4A As shown, the motherboard 2 can be transported via conveyor belt 5, and there is a support plate (not shown) supporting conveyor belt 5 below it. Figure 4A The arrow in the image indicates the direction of transport for conveyor belt 5. For example... Figure 4B As shown, the pickup device 6 includes a control structure 61, at least one adsorption structure 62, and at least one pusher structure 63. The control structure 61 drives the adsorption structure 62 and the pusher structure 63 to move them to their respective positions. Figure 4BThe arrows in the diagram indicate the direction of movement of the control structure 61. Specifically, the control structure 61 drives the adsorption structure 62 to move above the display panel 21, and drives the push rod structure 63 to move above the redundant panel 22. One end of the adsorption structure 62 is fixed to the control structure 61, and the other end is used to adsorb the display panel 21. One end of the push rod structure 63 is fixed to the control structure 61, and the other end can move up, down, or extend relative to the control structure 61. For example, in Figure 4, the adsorption structure 62 can adsorb the display panel 21 and move it to a set position under the drive of the control structure 61. The push rod structure 63 can generate a spring force between itself and the redundant panel 22 when the adsorption structure 62 adsorbs the display panel 21. Thus, when the adsorption structure 62 removes the display panel 21, the redundant panel 22 remains in its original position due to the spring force of the push rod structure 63 and its own gravity, thereby retaining the display panel 21 that needs to be retained. Figure 5 In some embodiments, these are the separated display panel 21 and redundant panel 22, wherein... Figure 5 (a) in the text refers to display panel 21. Figure 5 (b) in the diagram represents redundant panel 22. Additionally, in... Figure 4A and Figure 4B In the illustrated embodiment, the display panel 21 includes an array substrate 211 and a color filter substrate 212 disposed opposite to each other, and a liquid crystal layer located on the array substrate 211 and the color filter substrate 212. An encapsulant is disposed around the liquid crystal layer, and its specific function includes sealing the liquid crystal layer between the array substrate 211 and the color filter substrate 212. Correspondingly, the redundant panel 22 includes a redundant array substrate 221 and a redundant color filter substrate 222 disposed opposite to each other.

[0064] Figure 6 This is a schematic diagram of the process of picking up the display panel 21 in other embodiments. Figure 6 The arrows in the diagram indicate the direction of movement of the control structure 61. In some embodiments, such as... Figure 6 As shown, during the process of the adsorption structure 62 removing the display panel 21, sometimes due to contact, pressure, or friction between the display panel 21 and the redundant panel 22, the display panel 21 and the redundant panel 22 may collide (the collision location is, for example, located at...). Figure 5(As shown in positions A and B). The impact force between the display panel 21 and the redundant panel 22 may extend to the sealant, directly causing holes in the sealant. Furthermore, this impact will cause the horizontal crack 4 in the display panel 21 to extend and expand under stress. Excessive horizontal crack 4 may severely affect the performance of the display panel 21. For example, if the horizontal crack 4 is too large, it may extend to the location of the sealant, causing micro-cracks in the sealant as well, resulting in poor bonding between the sealant and the array substrate 211 or color filter substrate 212. Cracks or voids in the sealant will further lead to liquid crystal loss between the array substrate 211 or color filter substrate 212, or allow water and oxygen to infiltrate from the micro-cracks or holes in the sealant, severely affecting the performance of the display panel 21. When the impact force or the horizontal crack 4 spreads to a certain extent, the film layers in the array substrate 211 or color filter substrate 212 may also fracture, which will severely affect the product yield of the display panel 21.

[0065] In order to at least alleviate or solve one of the aforementioned technical problems, this disclosure provides a transmission device and an auxiliary dicing system.

[0066] Figure 7A This is a cross-sectional structural schematic diagram of the transmission device in some embodiments of this disclosure. Figure 7B This is a cross-sectional structural schematic diagram of the transmission device in some other embodiments of this disclosure.

[0067] In some embodiments, such as Figure 7A and Figure 7B As shown, this disclosure provides a transmission device, including: a conveyor belt 5, a first support member 10, a second support member 20 and a third support member.

[0068] The conveyor belt 5 is used to transport the cut display motherboard 2. The cut display motherboard 2 includes multiple display substrates and a redundant panel 22 located between adjacent display panels 21. In this embodiment, the cut display motherboard 2 refers to the display motherboard 2 that has been cut along the cutting path but has not yet been separated from the display panel 21 and the redundant panel 22, for example, as... Figure 3 The cut display motherboard 2 is shown.

[0069] The first support member 10, the second support member 20, and the third support member are arranged sequentially along the conveying direction of the conveyor belt 5. For example... Figure 7A and Figure 7BThe arrows in the diagram indicate the transmission direction of the conveyor belt 5. The first support member 10 includes a first support surface 101 for supporting the conveyor belt 5, the second support member 20 includes a support end for supporting the conveyor belt 5, and the third support member includes a third support surface 301 for supporting the conveyor belt 5. The first support surface 101 of the first support member 10 and the third support surface 301 of the third support member are located at a first height position, which means a position with a first height H1 relative to a reference horizontal plane a. The reference horizontal plane a is, for example, the horizontal ground where the equipment is located. That is, the first support surface 101 and the third support surface 301 can be understood as being on the same horizontal plane. At this time, at least a portion of the conveyor belt 5 located above the first support member 10 and the third support member is on the same horizontal plane, and at least a portion of the first support surface 101 and the third support surface 301 is in contact with the conveyor belt 5. The support end of the second support member 20 can rise and fall between a second height position and a third height position; that is, the support end of the second support member 20 can be at any position between the second height position and the third height position. The second height position is higher than the first height position, and the third height position is not higher than the first height position. The second height position refers to the position with a second height H2 relative to the reference horizontal plane a. The third height position refers to the position with a third height H3 relative to the reference horizontal plane a.

[0070] For example, the first height position is the same as the third height position. In this case, since the support end of the second support member 20 supports the conveyor belt 5, the position of the conveyor belt 5 corresponding to the second support member 20 can be at the second height position, the first height position, or any position between the second height position and the first height position.

[0071] Specifically, such as Figure 7A As shown, the support end of the second support member 20 is at the first height position, the first support surface 101 of the first support member 10 and the third support surface 301 of the third support member are also at the first height position, and the conveyor belt 5 is in contact with the first support surface 101 and the second support surface, respectively. Figure 7B As shown, the support end of the second support member 20 is at the second height position, while the first support surface 101 of the first support member 10 and the third support surface 301 of the third support member are at the first height position. At this time, the height of the conveyor belt 5 above the support end is higher than the height above the first support surface 101 and the third support surface 301. If the second height H2 is sufficiently high, the conveyor belt 5 above the first support surface 101 may not contact the first support surface 101 near the second support member 20, and the conveyor belt 5 above the third support surface 301 may also not contact the first support surface 101 near the second support member 20.

[0072] This embodiment of the present disclosure can lift the conveyor belt 5 at the corresponding position by the support end of the second support member 20, so that when the cut display mother board is conveyed to the support end position of the second support member 20, the display panel 21 and the redundant panel 22 are separated. This prevents the display panel 21 and the redundant panel 22 from colliding and causing or expanding the horizontal crack 4 when the picking device 6 picks up the display panel 21. Specifically, Figure 8 This is a schematic diagram of the structure of the transmission display motherboard 2 in some embodiments of this disclosure. For example... Figure 8 As shown, when the first support surface 101 and the third support surface 301 are at the first height position and the support end of the second support member 20 is at the second height position, since the second height H2 is higher than the first height position, a slope will be formed between the first support surface 101 and the support end, and a slope will be formed between the support end and the third support surface 301. Under the action of gravity, a gap will be generated between the adjacent display panel 21 and the redundant panel 22. In this way, when the pickup device 6 picks up the display panel 21, there will be no more collisions between the display panel 21 and the redundant panel 22. Therefore, the impact of collisions on the display panel 21 can be reduced. For example, the generation and expansion of horizontal cracks 4 can be reduced, and the horizontal cracks 4 can be prevented from affecting the performance of the display panel 21.

[0073] In some embodiments, such as Figure 7A , Figure 7B and Figure 8As shown, the second support member 20 includes a flipping member 202 and a rotating member 201. One end of the flipping member 202 is rotatably connected to the edge of the first support member 10 near the third support member. The flipping member 202 is capable of flipping relative to the first support member 10 about a first axis, which intersects the conveying direction of the conveyor belt 5. For example, the first axis is perpendicular to the conveying direction of the conveyor belt 5. The rotating member 201 is rotatably connected to the end of the flipping member 202 away from the first support member 10. It is understood that the end of the flipping member 202 connected to the first support member 10 and the end connected to the rotating member 201 are arranged along the conveying direction of the conveyor belt 5. The rotating member 201 is capable of rotating relative to the flipping member 202 about its own axis. The supporting end of the second support member 20 is the end of the rotating member 201 facing the conveyor belt 5. Understandably, after the flipper 202 flips around the first axis, it can move the rotating member 201 from the first height position to any position between the second height position and the first height position. This results in the support end being higher than the first support member 10 and the third support member 30, causing the conveyor belt 5 to be lifted by the support end and protrude. This allows the display panel 21 and the redundant panel 22 to climb and descend at the front and rear positions of the support end, thus separating the display panel 21 and the redundant panel 22. Furthermore, during the process of the flipper 202 driving the rotating member 201 upwards, the rotating member 201 contacts the conveyor belt 5, and the rotating member 201 can rotate relative to the flipper 202 around its own axis, thereby reducing friction between the support end and the conveyor belt 5.

[0074] Figure 9 This is a partial structural schematic diagram of the transmission device in some embodiments of this disclosure. Figure 10 This is a partial structural schematic diagram of the transmission device in some other embodiments of this disclosure. Figure 11 This is a partial structural schematic diagram of the transmission device in some other embodiments of this disclosure. Figure 12 This is a partial structural schematic diagram of the transmission device in some other embodiments of this disclosure. Figure 13 This is a partial structural schematic diagram of the transmission device in some other embodiments of this disclosure. Figure 14 This is a partial structural schematic diagram of the transmission device in some other embodiments of this disclosure. Figure 15 This is a schematic diagram of the structure of the mounting base 50 in other embodiments of this disclosure.

[0075] In some embodiments, such as Figure 9 and Figure 10As shown, the end of the flipping member 202 away from the first support member 10 has a mounting groove 203. The second support member 20 also includes a rotating shaft 204. The rotating shaft 204 is located in the mounting groove 203, and both ends of the rotating shaft 204 are fixed to the inner wall of the mounting groove 203. A rotating member 201 is sleeved on the rotating shaft 204 and can rotate relative to the rotating shaft 204. For example, the rotating member 201 can specifically be a roller. This arrangement has a simple structure, and by setting the diameter of the rotating member 201, it can be ensured that when the flipping member 202 is in a horizontal state, the rotating member 201 can still provide support for the conveyor belt 5.

[0076] The number of mounting slots 203 can be multiple, and each mounting slot 203 is provided with a rotating shaft 204 and multiple rotating parts 201, thereby improving the stability of the second support member 20 supporting the conveyor belt 5.

[0077] Optionally, both ends of the rotating shaft 204 are at the same height. Having both ends of the rotating shaft 204 at the same height ensures stable support for the conveyor belt 5 as the rotating component 201 rises along with the tilting component 202.

[0078] Optionally, a spacer 205 is provided between adjacent rotating parts 201, and a spacer 205 is also provided between the rotating part 201 and the mounting groove 203, so as to provide a certain damping force when the rotating part 201 rotates, and prevent the rotating part 201 from slipping.

[0079] Alternatively, the rotating element 201 may be made of metal, such as copper. The spacer may be made of nylon.

[0080] In some embodiments, such as Figure 9 and Figure 10 As shown, the flipping member 202 is connected to the first support member 10 via the hinge member 40.

[0081] Optionally, the hinge 40 may be, for example, a hinge.

[0082] It should be noted that the specific way in which the hinge 40 is connected to the flipping member 202 and the first support member 10 can be selected by those skilled in the art based on the actual situation.

[0083] In some embodiments, such as Figure 10 and Figure 11 As shown, the transmission device also includes: a mounting base 50, a first rotating shaft 60, a drive mechanism 90, and a linkage mechanism 70.

[0084] The mounting base 50 is located on the side of the second support member 20 away from the conveyor belt 5, and the mounting base 50 has a mounting hole. A first rotating shaft 60 passes through the mounting hole, and the extending direction of the first rotating shaft 60 intersects the conveying direction of the conveyor belt 5. For example, the extending direction of the first rotating shaft 60 is perpendicular to the conveying direction of the conveyor belt 5. For example, the extending direction of the first rotating shaft 60 is parallel to the extending direction of the aforementioned first axis. A drive mechanism 90 is connected to the first rotating shaft 60 and is used to drive the first rotating shaft 60 to rotate along its own axis. A linkage mechanism 70 is connected between the first rotating shaft 60 and the tilting member 202, and is used to convert the rotational motion of the first rotating shaft 60 into the tilting motion of the tilting member 202.

[0085] In this embodiment, a driving mechanism 90 drives a first rotating shaft 60 to rotate along its own axis. The rotation of the first rotating shaft 60 then drives a linkage mechanism 70 to rotate, which in turn causes the flipping member 202 to flip. Since the first rotating shaft 60 has an extending direction, the extending direction of the rotating rod can be the same as the extending direction of the rotating member. Furthermore, multiple linkage mechanisms 70 can be used to connect the first rotating shaft 60 and the flipping member 202. In this case, this embodiment can cause the flipping member 202 to flip as a whole through the driving mechanism 90 and the first rotating shaft 60, facilitating overall control of the flipping of the flipping member 202 and ensuring the synchronization and uniformity of the flipping.

[0086] In some embodiments, such as Figure 10 and Figure 14 As shown, the linkage mechanism 70 includes a first link 701 and a second link 702. The extension direction of the first link 701 intersects the extension direction of the first rotation shaft 60, and the first end of the first link 701 is fixedly connected to the first rotation shaft 60. The first end of the second link 702 is rotatably connected to the second end of the first link 701, and the second end of the second link 702 is connected to the flipping member 202.

[0087] In this embodiment, the first end of the first connecting rod 701 is fixedly connected to the first rotating shaft 60. Therefore, the first connecting rod 701 can rotate around the axis of the first rotating shaft 60. The first end of the second connecting rod 702 is rotatably connected to the second end of the first connecting rod 701 through a connecting shaft 80. The second end of the second connecting rod 702 is connected to the flipping member 202. Therefore, under the rotation of the first connecting rod 701, the first end of the second connecting rod 702 will also rotate around the axis of the first rotating shaft 60, thereby causing the flipping member 202 to flip.

[0088] Optionally, the length of the second link 702 is greater than the length of the first link 701. If the length of the first link 701 is smaller, then when the first link 701 rotates a certain angle following the axis of the first rotating shaft 60, the rotation distance of the second end of the first link 701 is relatively small. Consequently, the rotation distance of the first end of the second link 702, which is rotatably connected to the second end of the first link 701, is also relatively small. Therefore, the second end of the second link 702 can drive the flipping member 202 to flip while the first end of the second link 702 rotates a relatively small distance. Clearly, this embodiment of the present disclosure can easily achieve the flipping control of the flipping member 202.

[0089] In some embodiments, such as Figures 10 to 15 As shown, the mounting base 50 includes a mounting plate 501 and at least one mounting platform 502. The mounting plate 501 has a clearance hole through which the linkage mechanism 70 passes. At least one mounting platform 502 is fixed to the side of the mounting plate 501 away from the conveyor belt 5, and a mounting hole penetrates the mounting platform 502. For example, the mounting platform 502 may be a shaft seat.

[0090] Optionally, in such Figure 14 and Figure 15 In the illustrated embodiment, the transmission device further includes a mounting bracket 100. A mounting base 50 and a second support member 20 are located on opposite sides of the mounting bracket 100. The mounting bracket 100 has an clearance opening through which the linkage mechanism 70 passes.

[0091] It should be noted that the specific methods of fixing and fixed connection in the embodiments of this disclosure can be selected by those skilled in the art according to the actual situation. For example, screws, nuts, and their mutual cooperation can be used for fixed connection. Furthermore, the fixing part is not limited in this embodiment.

[0092] In some embodiments, such as Figure 12 and Figure 13 As shown, the drive mechanism 90 includes a drive handle 901, a second rotating shaft 902, and a transmission unit 903. The drive handle 901 is connected to the second rotating shaft 902. The drive handle 901 drives the second rotating shaft 902 to rotate along its own axis. The transmission unit 903 connects the second rotating shaft 902 and the first rotating shaft 60. The transmission unit 903 drives the first rotating shaft 60 to rotate synchronously under the rotation of the second rotating shaft 902.

[0093] In some embodiments, such as Figure 12 and Figure 13As shown, the transmission unit 903 includes a first pulley 931, a second pulley 932, and a synchronous belt 933. The first pulley 931 is mounted on the first rotating shaft 60. The second pulley 932 is mounted on the second rotating shaft 902. The synchronous belt 933 is wound around the first pulley 931 and the second pulley 932.

[0094] In this embodiment, the synchronous rotation of the first rotating shaft 60 and the second rotating shaft 902 can be achieved by the synchronous belt 933, that is, the drive mechanism 90 drives the first rotating shaft 60 to rotate around its own axis, thereby driving the flipping member 202 to flip.

[0095] In some embodiments, such as Figure 13 As shown, the dimension W of the second support member 20 in the width direction of the conveyor belt 5 is greater than or equal to the width of the conveyor belt 5.

[0096] In this embodiment of the disclosure, the dimension of the second support member 20 in the width direction of the conveyor belt 5 is greater than or equal to the width of the conveyor belt 5. A sufficient number of rotating members 201 can be provided at the end of the second support member 20 away from the first support member 10, so as to ensure that the second support member 20 can provide stable support for the conveyor belt 5 when it is in contact with the conveyor belt 5.

[0097] In some embodiments, this disclosure provides an auxiliary dicing system, including a transmission device as described in any embodiment of this disclosure and a pickup device 6. The pickup device 6 is configured to pick up the display panel 21 transmitted by the transmission device.

[0098] In this embodiment of the present disclosure, the transmission device can separate the display panel 21 and the redundant panel 22 in the cut display motherboard 2. Furthermore, when the picking device 6 picks up the display panel 21, there will be no more collisions between the display panel 21 and the redundant panel 22, thereby reducing the impact on the performance of the display panel 21.

[0099] In some embodiments, the pickup device 6 includes a control structure 61, at least one adsorption structure 62, and at least one pusher structure 63. The control structure 61 drives the adsorption structure 62 and the pusher structure 63. Both the adsorption structure 62 and the pusher structure 63 are connected to the control structure 61. The control structure 61 is configured to control the adsorption structure 62 to adsorb the display panel 21, and to control the pusher mechanism 63 to move up and down relative to the control structure 61, so that the pusher mechanism 63 generates a pushing force toward or away from the redundant panel 22.

[0100] For example, one end of the adsorption structure 62 is connected to the control structure 61, and the other end of the adsorption structure 62 has adsorption capacity and can be used to adsorb the display panel 21. The push rod structure 63 is connected to the control structure 61, and the push rod structure 63 can move up and down relative to the control structure 61. Specifically, during the process of picking up the display panel 21, the control structure 61 controls the adsorption structure 62 to adsorb the display panel, and during the process of controlling the adsorption structure 62 to adsorb the display panel, the control structure 61 controls the push rod structure 63 to move away from the redundant panel 22. After the control structure 61 completes the adsorption, the control structure 61 controls the push rod structure 63 to generate a pushing force on the redundant panel 22, controlling the adsorption structure 62 to pick up the display panel 21 while keeping the redundant panel in its original position.

[0101] Furthermore, a buffer is provided at the end of the push rod structure 63 away from the control structure 61 to avoid breakage or other problems when forces are generated between the push rod structure 63 and the redundant panel 22.

[0102] In this embodiment of the present disclosure, when the adsorption structure 62 completes the adsorption of the display panel 21 and drives the display panel 21 to move under the drive of the control structure 61, the push rod structure 63 can generate a pushing force on the redundant panel 22, thereby keeping the redundant panel 22 in its original position. Therefore, the auxiliary splitting system in this embodiment of the present disclosure can effectively separate the display panel 21 and the redundant panel 22 without causing collision between them.

[0103] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
