Description

Technical Field

[0001] The present application relates to the technical field of substrate glass packaging, and in particular to a TFT substrate glass packaging buffer device and a TFT substrate glass packaging equipment. Background Art

[0002] In the field of liquid crystal display device manufacturing, in the process of packaging semi-finished TFT substrate glass, the three components of the unloading component, the paper laying component and the packaging component constitute a complete automated packaging system. Among them, the paper laying component is responsible for straightening, cutting and flattening the roll paper for subsequent operations. When the semi-finished substrate glass arrives at the semi-finished product packaging station, the unloading component will remove it from the transmission line and place it on the paper laying platform with the paper laid. The paper laying component will cut and flatten the paper according to specific specifications and requirements to ensure the appropriate size and packaging effect. Finally, the packaging component will take away the semi-finished TFT substrate glass with the paper laid on it at the same time, and place it on a fixed tray to complete the packaging of the semi-finished TFT substrate glass. For example, Chinese Patent 201720363762.7 discloses a glass substrate transmission device and a glass substrate packaging device and their clamping devices for realizing paper packaging of substrate glass.

[0003] However, the difference in working speed between the paper laying component and the subsequent packaging component will lead to a lack of coordination between the two components, resulting in pauses or delays. For example, if the paper laying component fails during operation, it will cause the packaging paper to not be laid in time, resulting in the unloading component and the packaging component also not being able to operate normally, thus causing the entire system to shut down due to a single failure point, affecting the reliability and stability of the production line.

[0031] Figures 1 to 5 An embodiment of the TFT substrate glass packaging buffer device of the present application is schematically shown.

[0032] like Figures 1 to 5 As shown, the present application discloses a TFT substrate glass packaging cache device, which includes: a cache component 20, the cache component 20 includes a plurality of cache brackets, the plurality of cache brackets are evenly arranged around a paper laying platform 10 of the paper laying component, each cache bracket is provided with a plurality of clamping mechanisms 21 along the vertical direction, and the cache bracket clamps and caches a plurality of packaging papers at vertical intervals above the paper laying platform 10 through the clamping mechanisms 21.

[0033] Through the above design, the TFT substrate glass packaging cache device of the embodiment of the present application can ensure a continuous supply of packaging paper by caching multiple packaging papers in advance, thereby smoothing the production process, making the speed matching between the paper laying component and the packaging component more coordinated, reducing downtime and production delays, improving production efficiency, and providing stability and reliability of the production line.

[0034] In some embodiments of the present application, Figures 2 to 4 As shown, the cache bracket includes: a first frame 23, a first synchronous belt (not shown), a first driving mechanism 22 and a clamping mechanism 21. The first frame 23 is an annular structure arranged in the vertical direction. The first synchronous belt is sleeved on the first frame 23 and can rotate around the first frame 23. A plurality of clamping mechanisms 21 are installed at intervals on the first synchronous belt. The first driving mechanism 22 is connected to the first synchronous belt to drive the first synchronous belt to rotate to drive the clamping mechanism 21 to move up and down. Among them, the first driving mechanism 22 can be any type of driving mechanism that can realize rotational drive, including a combination of a motor and a gear structure, etc. Since this part of the structure and working principle is not an improvement point of the embodiment of the present application, it will not be described in detail. Through the cyclic lifting and lowering operation of multiple clamping mechanisms 21, the cache assembly 20 can better cooperate with the paper laying assembly and the packaging assembly.

[0035] Specifically, the first driving mechanism 22 drives the first synchronous belt to rotate, thereby driving each clamping mechanism 21 to rise in sequence. In actual application, each clamping mechanism 21 moves to the paper receiving height close to the paper laying platform 10 in sequence under the rotation of the first synchronous belt, receives the packaging paper laid by the paper laying component at the paper receiving height, and clamps the received packaging paper and rises, thereby realizing the layer-by-layer rising cache of multi-layer packaging paper. Then, the unloading component unloads the TFT substrate glass (semi-finished product) onto the packaging paper on the top layer of the cache component 20 (because the packaging paper has sufficient strength, the glass will not fall on it), and then the packaging component takes away the packaging paper on the top layer and the TFT substrate glass on the packaging paper together, and moves to the packaging station (such as an A-shaped frame) for packaging. At the same time, the first driving mechanism 22 of the cache component 20 runs again to drive the first synchronous belt to rotate a unit length, so that the clamping mechanism 21 at the second height rises to the top layer position for the next packaging, and the clamping mechanism 21 at the bottom layer continues to clamp the packaging paper to rise to achieve caching.

[0036] In this way, only the top layer of wrapping paper of the buffer assembly 20 is taken away each time packaging is performed, and the wrapping paper of each layer below in the buffer assembly 20 can be used as a buffer paper, which is used to provide spare paper when the paper laying assembly fails (such as when paper jams or paper needs to be replaced, etc.), thereby avoiding the overall shutdown of the packaging system. It can be understood that when the failure of the paper laying assembly is eliminated and the paper laying is normal, the movement of the first driving mechanism 22 can be accelerated manually or by program setting, so that the buffer assembly 20 re-clamps multiple layers of wrapping paper to achieve caching.

[0037] In some embodiments of the present application, Figures 2 to 4 As shown, the first frame 23 is a round ring structure, and the clamping mechanism 21 clamps the packaging paper when it moves to the straight section on one side of the first frame 23, so that when the first driving mechanism 22 drives the first synchronous belt to move, the clamping mechanism 21 maintains vertical lifting to stably clamp the packaging paper to rise. In the embodiment of the present application, a fixed bracket (not shown) is arranged below the first frame 23, and the fixed bracket suspends the first frame 23 on the paper laying platform 10 to ensure that there is space at the bottom of the first frame 23 for the clamping mechanism 21 to rotate circumferentially.

[0038] In some embodiments of the present application, Figures 2 to 4 As shown, the clamping mechanism 21 includes: a clamping jaw 211 and a cylinder 212, wherein the cylinder 212 is connected to the clamping jaw 211 and drives the clamping jaw 211 to open and close. Among them, the inner surface of the clamping jaw 211 can be provided with anti-slip material to increase friction and improve the reliability of clamping the packaging paper.

[0039] In some embodiments of the present application, Figure 1As shown, the paper laying platform 10 is rectangular in shape, and four groups of buffer brackets are provided, and the four groups of buffer brackets are respectively provided at the four corners of the paper laying platform 10 to clamp the four corners of the packaging paper respectively and lift the packaging paper. Among them, the driving signals between the groups of buffer brackets are synchronized to ensure that the clamping mechanisms 21 thereon can be lifted and lowered horizontally together.

[0040] In some embodiments of the present application, Figure 1 As shown, the TFT substrate glass packaging buffer device also includes: an auxiliary supporting assembly 30. The auxiliary supporting assembly 30 includes a supporting mechanism 31, which can extend below the clamping mechanism 21 to support the packaging paper and the TFT substrate glass placed on the packaging paper, thereby preventing the product from falling due to paper damage or other reasons.

[0041] In some embodiments of the present application, the auxiliary support assembly 30 can be arranged similarly to the structure of the cache assembly, that is, the auxiliary support assembly 30 includes: a second frame, a second synchronous belt, a second driving mechanism and a supporting mechanism 31. The second frame is a ring structure arranged in the vertical direction, the second synchronous belt is sleeved on the second frame and can rotate around the second frame, a plurality of supporting mechanisms 31 are installed on the second synchronous belt at intervals, and the second driving mechanism is connected to the second synchronous belt to drive the second synchronous belt to rotate to drive the supporting mechanism 31 to move up and down. Figures 2 to 4 As shown, the clamping mechanism 21 is replaced by a supporting mechanism 31, thus forming a corresponding auxiliary supporting assembly 30. The auxiliary supporting assembly 30 in this embodiment can use multiple sets of supporting mechanisms 31 to respectively cooperate with each layer of the clamping mechanism 21.

[0042] In some embodiments of the present application, Figure 1 and Figure 5As shown, the auxiliary supporting assembly 30 includes: a rotating support rod 32, a third driving mechanism 33 and a supporting mechanism 31. The rotating support rod 32 is arranged in the vertical direction. The supporting mechanism 31 uses, for example, a supporting plate, which is mounted on the rotating support rod 32 and is located below the clamping mechanism 21 at the top of the cache bracket. The third driving mechanism 33 is connected to the rotating support rod 32 and can drive the rotating support rod 32 to rotate reciprocatingly so that the supporting mechanism 31 repeatedly extends under the clamping mechanism 21 at the top of the cache bracket. In actual use, each time before the unloading assembly unloads the TFT substrate glass, the third driving mechanism 33 drives the rotating support rod 32 to rotate, so that the supporting mechanism 31 turns to the inside to extend under the clamping mechanism 21 located on the top layer, so as to support the packaging paper on the top layer and the TFT substrate glass to be placed thereon. After the packaging assembly takes away the top layer of packaging paper and the TFT glass substrate thereon, the third driving mechanism 33 drives the rotating support rod 32 to rotate, so that the supporting mechanism 31 turns to the outside to avoid the clamping mechanism 21 and the packaging paper that need to be raised next, and so on, the auxiliary support of the packaging paper and the TFT glass substrate at the top layer is always achieved. The auxiliary supporting assembly 30 of this embodiment has a simpler structure, low cost, high reliability, and is not prone to error.

[0043] In some embodiments of the present application, Figure 1 As shown, multiple groups of auxiliary supporting components 30 are symmetrically arranged around the paper laying platform 10 to achieve balanced support of the packaging paper and the TFT substrate glass to prevent the packaging paper and the TFT substrate glass from deflecting or falling.

[0044] According to another aspect of the present application, a TFT substrate glass packaging device is disclosed, which includes a TFT substrate glass packaging buffer device as described in any of the above embodiments to achieve multiple buffering of packaging papers, thereby improving production continuity and improving production efficiency.

[0045] In summary, the TFT substrate glass packaging buffer device of the present application includes a buffer assembly, the buffer assembly includes multiple groups of buffer brackets, the multiple groups of buffer brackets are evenly arranged around the paper laying platform of the paper laying assembly, each buffer bracket is provided with multiple clamping mechanisms in the vertical direction, and the buffer bracket clamps and caches multiple sheets of packaging paper at intervals vertically above the paper laying platform through the clamping mechanisms. The present application can cache multiple sheets of packaging paper in advance to ensure a continuous supply of packaging paper, thereby smoothing the production process, making the speed matching between the paper laying assembly and the packaging assembly more coordinated, reducing downtime and production delays, improving production efficiency, and providing stability and reliability of the production line.

[0046] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
