Description

Technical Field

[0001] This utility model belongs to the field of glass substrate processing technology, and in particular relates to a rotating device for glass cleaning. Background Technology

[0002] With the rapid development of high-end manufacturing fields such as flat panel displays, photovoltaics, and semiconductors, glass substrates, as key carriers, directly determine the yield of subsequent processes such as thin film deposition, photolithography, and encapsulation based on their surface cleanliness and positional accuracy. Therefore, after glass substrates have undergone processes such as cutting, grinding, chamfering, and thinning, they must be cleaned through multiple stages to remove adhering particles, metal ions, and organic contaminants, and high-speed, non-destructive transfer and relocation must be achieved between these stages.

[0003] Existing production lines generally use a combination of "roller assembly + lifting and rotating device" to complete the post-cleaning turning and conveying of substrates. The typical process is as follows: when the glass substrate is carried by the roller assembly and conveyed to the designated station, the lifting and rotating mechanism arranged between adjacent rollers rises, lifting the glass substrate off the roller surface; subsequently, the rotating platform drives the glass substrate to rotate 90° / 180° to achieve edge cleaning, orientation adjustment, or alignment with the inlet direction of the next cleaning chamber; after rotation, the lifting mechanism descends, and the glass substrate falls back onto the roller assembly, continuing to be conveyed downstream. However, the existing lifting and rotating device support structure is mostly a ring bracket. When the ring bracket rises, it makes rigid or semi-rigid contact with the back of the glass. At the moment of lifting, due to asynchronous multi-point support, excessive impact force, or local stress concentration, bending deformation or even instantaneous fragmentation can easily occur. Even if no obvious crack occurs, local micro-cracks will propagate during subsequent thermal processes, leading to hidden scrap and affecting the yield of glass substrates. Utility Model Content

[0004] In view of this, the present invention aims to provide a rotating device for glass cleaning to solve the problem that the glass substrate is easily damaged when the support structure of the existing lifting and rotating device lifts the glass substrate.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A rotating device for glass cleaning includes a rotating lifting platform and a support member mounted on the platform. The support member has a through hole for rollers to pass through, and a receiving cavity is provided inside the support member. An inflatable airbag is provided inside the receiving cavity. The support member has a buffer mechanism, which includes a buffer pad and a lifting member. The buffer pad is located above the support member, and a buffer gap exists between the buffer pad and the support member. The support member has a mounting hole that mates with the lifting member and communicates with the receiving cavity. One end of the lifting member extending into the receiving cavity is provided with a limiting plate, and the other end is connected to the buffer pad. The limiting plate abuts against the inflatable airbag, and the inflatable airbag is located between the limiting plate and the cavity wall.

[0006] Furthermore, two guide plates are provided on both sides of the limiting plate, and the two guide plates are arranged in an H-shape with the limiting plate. Each guide plate slides in cooperation with the cavity wall.

[0007] Furthermore, the mounting hole is a strip-shaped hole, and the length direction of the strip-shaped hole is the same as the length direction of the support member.

[0008] Furthermore, the support member is provided with a removable sealing member at the position corresponding to the receiving cavity.

[0009] Furthermore, the sealing component is provided with an assembly hole to facilitate the extension of the air valve of the inflatable airbag.

[0010] Furthermore, sealing elements are provided between the sealing element and the cavity wall, and between the airbag valve and the inner wall of the assembly hole.

[0011] Furthermore, the buffer pad is connected to the support member by elastic sheets around its perimeter. One end of the elastic sheet is connected to the support member, and the other end is connected to the buffer pad.

[0012] Furthermore, the support member is a cross-shaped structural member.

[0013] Furthermore, the support member is a mesh-like structural member.

[0014] Compared with the prior art, the rotating device for glass cleaning described in this utility model has the following advantages: This invention discloses a rotating device for glass cleaning, which not only provides stable support for the glass substrate, preventing damage, but also drives the glass substrate to move up, down, and rotate stably, thus improving the yield rate of the glass substrate. By employing a descending buffer pad, the buffer pad provides gradual support to the glass substrate during descent, ultimately enabling the support component to provide multi-point support for the glass substrate, preventing damage caused by deformation or localized stress concentration during support. Simultaneously, by utilizing an inflatable airbag to support the limiting plate, and the limiting plate to support the lifting component and the buffer pad, the elastic deformation of the inflatable airbag and the compression of the gas inside the airbag not only provide secondary cushioning for the glass substrate on the buffer pad, but also effectively absorb the impact force when the glass substrate contacts the buffer pad, reducing the probability of micro-cracks appearing in the glass substrate due to excessive impact force.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of 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.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] A rotating device for glass cleaning, such as Figures 1 to 4 As shown, the device includes a rotating lifting platform and a support member 1 mounted on the rotating lifting platform. The support member 1 has a through hole to facilitate the passage of rollers 2. This utility model does not involve any improvement to the rotating lifting platform. Those skilled in the art can select a suitable rotating lifting platform according to actual needs. The support member 1 and the platform of the rotating lifting platform can be stably assembled by means of screw connection or other methods, as long as the platform of the rotating lifting platform can drive the support member 1 to rise, fall and rotate. Further details are omitted here.

[0022] The main improvement of this utility model lies in the support member 1, specifically, the support member 1 has a receiving cavity 13, and the receiving cavity 13 has an inflatable airbag 12; the support member 1 has a buffer mechanism, which includes a buffer pad 3 and a lifting member 4. The buffer pad 3 is located above the support member 1, and there is a buffer gap between the buffer pad 3 and the support member 1. The support member 1 has a mounting hole 5 that cooperates with the lifting member 4, and the mounting hole 5 communicates with the receiving cavity 13. One end of the lifting member 4 that extends into the receiving cavity 13 has a limiting plate 8, and the other end is connected to the buffer pad 3. The limiting plate 8 and the inflatable airbag 12 are in abutting cooperation, and the inflatable airbag 12 is located between the limiting plate 8 and the cavity wall of the receiving cavity 13. Among them, the limiting plate 8 is set horizontally, and the inflatable airbag 12 is located below the limiting plate 8.

[0023] For example, the buffer pad 3 can be made of rubber or silicone. The lifting component 4 is fixedly connected to the buffer pad 3, or the lifting component 4 and the buffer pad 3 are integrally formed. The lifting component 4 and the limiting plate 8 can be connected by means of adhesive, snap-fit, screw connection, etc. As long as the buffer pad 3 can be pressed down by the gravity of the glass substrate when the glass substrate comes into contact with the buffer pad 3, the lifting component 4 will be driven to push the limiting plate 8 downward, so that the limiting plate 8 can squeeze the inflatable airbag 12.

[0024] When the glass substrate moves onto the support 1 and comes into contact with the buffer pad 3, the buffer pad 3 moves downwards. Even if the glass substrate bends locally, the buffer pad 3 can gradually descend, using the descent to offset the deformation of the glass substrate. This allows the support 1 to contact all parts of the glass substrate, ultimately providing multi-point support and effectively reducing damage to the glass substrate caused by asynchronous multi-point support or localized stress concentration. Furthermore, by using the inflatable airbag 12 to support the limiting plate 8, the inflatable airbag 12 can effectively absorb the impact force when the glass substrate contacts the buffer pad 3, improving the buffering effect of the buffer pad 3 and preventing localized cracks caused by direct rigid or semi-rigid contact between the glass substrate and the support 1.

[0025] Using the above-described configuration, the descendable buffer pad 3 provides gradual support to the glass substrate during its descent, ultimately enabling the support member 1 to provide multi-point support for the glass substrate. This prevents damage to the glass substrate caused by deformation or localized stress concentration during the support process. Simultaneously, by using the inflatable airbag 12 to support the limiting plate 8, and the limiting plate 8 to support the lifting member 4 and the buffer pad 3, the elastic deformation of the inflatable airbag 12 and the compression of the gas inside it not only provide secondary cushioning for the glass substrate on the buffer pad 3, but also effectively absorb the impact force when the glass substrate contacts the buffer pad 3. This reduces the probability of micro-cracks appearing in the glass substrate due to excessive impact force, thus improving the production yield of the glass substrate.

[0026] In a preferred embodiment of this invention, two guide plates 9 are provided on both sides of the limiting plate 8. The two guide plates 9 are arranged in an H-shape with the limiting plate 8, and each guide plate 9 slides against the wall of the receiving cavity 13. For example, the guide plates 9 are vertically arranged and fixedly connected to the limiting plate 8.

[0027] Using the above-described configuration, the H-shaped guide plate 9 and limiting plate 8 have higher structural strength. Furthermore, the sliding fit between the guide plate 9 and the cavity wall of the receiving cavity 13 improves the stability of the limiting plate 8 during lifting and lowering, preventing tilting and ensuring that the lifting component 4 can stably compress the inflatable airbag 12 by pressing downwards against the limiting plate 8. In addition, grooves can be formed on the upper and lower surfaces of the H-shaped guide plate 9 and limiting plate 8. The lifting component 4 can cooperate with these grooves for a stable connection, and the inflatable airbag 12 can be confined within the grooves, preventing movement of the inflatable airbag 12 during compression and providing sufficient deformation space for the inflatable airbag 12, thus ensuring the effective cooperation between the limiting plate 8 and the inflatable airbag 12.

[0028] In a preferred embodiment of this invention, the mounting hole 5 is a strip-shaped hole, and the length direction of the strip-shaped hole is the same as the length direction of the support member 1. Correspondingly, the lifting member 4 is also a strip-shaped structural member. By using a strip-shaped hole to cooperate with the lifting member 4, it is beneficial to increase the contact area between the lifting member 4 and the buffer pad 3 and the limiting plate 8, thereby ensuring that the lifting member 4 can stably provide limiting support for the buffer pad 3 under the support of the inflatable airbag 12 and the limiting plate 8.

[0029] In a preferred embodiment of this invention, a detachable sealing member 6 is provided on the support member 1 at a position corresponding to the receiving cavity 13. Specifically, the support member 1 has an opening at its end, which communicates with the receiving cavity 13. The sealing member 6 and the opening at the end of the support member 1 can be connected by a plug-in joint to achieve detachable assembly of the sealing member 6 on the support member 1. Those skilled in the art can also choose other methods to install the sealing member 6 according to actual needs, such as threaded connection, screw connection, etc., to achieve detachable assembly of the sealing member 6 on the support member 1 and to seal the opening, which will not be elaborated here.

[0030] Using the above-described configuration, components such as the inflatable airbag 12 and the limiting plate 8 can be easily replaced and maintained by disassembling the sealing component 6, which helps to reduce the difficulty of assembling and maintaining this support component 1. During assembly, the limiting plate 8 and the inflatable airbag 12 can be assembled into the receiving cavity 13 first, with the inflatable airbag 12 positioned below the limiting plate 8. Then, the lifting component 4 and the buffer pad 3 can be assembled, ensuring that the lifting component 4 is connected to the limiting plate 8. Finally, the sealing component 6 can be installed to seal the opening, ensuring that the limiting plate 8 and the inflatable airbag 12 can be stably assembled in the receiving cavity 13, so that the limiting plate 8 and the inflatable airbag 12 can continuously and stably provide limiting support for the buffer pad 3.

[0031] Optionally, the sealing component 6 is provided with an assembly hole 10 to facilitate the extension of the valve 7 of the inflatable airbag 12. By providing the assembly hole 10, the valve 7 of the inflatable airbag 12 can extend out of the support component 1, which facilitates the operator to periodically inspect and inflate / deflat the inflatable airbag 12, thereby ensuring that the air pressure inside the inflatable airbag 12 can always be kept at the optimal state.

[0032] Optionally, sealing elements 11 are provided between the sealing element 6 and the wall of the receiving cavity 13, and between the valve 7 of the inflatable airbag 12 and the inner wall of the assembly hole 10. For example, the sealing element 11 can be a sealing ring, and annular grooves for installing the sealing ring can be provided on both the inner wall of the assembly hole 10 and the outer peripheral wall of the sealing element 6. Those skilled in the art can also select other suitable sealing elements 11 and their installation methods according to actual needs, as long as sealing can be achieved between the sealing element 6 and the wall of the receiving cavity 13, and between the valve 7 of the inflatable airbag 12 and the inner wall of the assembly hole 10; further details are omitted here.

[0033] By using the above-mentioned setup, the sealing component 6 can ensure the isolation between the receiving cavity 13 and the outside of the support component 1 after installation, reducing the possibility of foreign objects such as sewage and dust entering the receiving cavity 13, thereby ensuring the stability of the lifting and lowering of the limiting plate 8 inside the receiving cavity 13, and helping to improve the service life of the inflatable airbag 12.

[0034] In practical applications, the buffer pad 3 can also be connected to the support member 1 around its perimeter via elastic sheets 14. One end of the elastic sheet 14 is connected to the support member 1, and the other end is connected to the buffer pad 3. The elastic sheet 14 can be made of rubber or silicone, and can be integrally molded with the buffer pad 3. The elastic sheet 14 and the support member 1 can be connected by means of adhesive, snap-fit, screw connection, etc. If necessary, a sealing structure, such as a sealing ring, can also be provided between the elastic sheet 14 and the support member 1.

[0035] By using the elastic sheet 14 to connect the buffer pad 3 and the support member 1, foreign objects such as sewage and dust can be prevented from entering the buffer gap and then entering the receiving cavity 13 through the mounting hole 5. This further improves the sealing performance of the receiving cavity 13 and ensures that the limiting plate 8 in the receiving cavity 13 can continuously and stably rise and fall, preventing the buffer mechanism from failing due to the limiting plate 8 getting stuck.

[0036] In a preferred embodiment of this invention, the support member 1 is a cross-shaped structure or a mesh structure. Compared with other structures, the cross-shaped and mesh structures of the support member 1 have a larger supporting area, which is beneficial to improving the supporting effect of the support member 1 on the glass substrate.

[0037] This invention discloses a rotating device for glass cleaning, which not only provides stable support for the glass substrate, preventing damage, but also drives the glass substrate to move up, down, and rotate stably, thus improving the yield rate of the glass substrate. By employing a descending buffer pad, the buffer pad provides gradual support to the glass substrate during descent, ultimately enabling the support component to provide multi-point support for the glass substrate, preventing damage caused by deformation or localized stress concentration during support. Simultaneously, by utilizing an inflatable airbag to support the limiting plate, which in turn supports the lifting component and the buffer pad, the elastic deformation of the inflatable airbag and the compression of the gas inside the airbag not only provide secondary cushioning for the glass substrate on the buffer pad but also effectively absorb the impact force when the glass substrate contacts the buffer pad, reducing the possibility of micro-cracks appearing in the glass substrate due to excessive impact force.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
