Description

Technical Field

[0001] This invention relates to the field of glass substrate processing technology, and more specifically to a protective device for glass substrate grinding processing. Background Technology

[0002] In the manufacturing process of liquid crystal displays, the grinding of glass substrates is one of the key steps. Grinding of glass substrates is one of the key processes in the manufacturing of electronic display devices such as liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs). Glass substrates are usually required to have high flatness, low surface roughness and a defect-free surface to meet the requirements of subsequent processes (such as coating, photolithography, etc.).

[0003] Taking appropriate protective measures during the glass substrate grinding process is crucial to ensure product quality and operational safety.

[0004] However, the protective measures for glass substrates during the current glass substrate grinding process are still insufficient: Firstly, because glass substrates are thin and fragile, glass components on the substrate will be ground off during the grinding process. These components will be ground off along with the grinding liquid due to the rotational force of the grinding mechanism. The splashed material will not only contaminate the machine but also splash to the outside, and may even affect personnel outside.

[0005] Secondly, when personnel extract the glass substrate after grinding, the grinding slurry that remains on the glass substrate during grinding will drip off the substrate during extraction. This dripping will not only fall onto the machine but also onto the ground, making it difficult to keep the working environment clean and tidy.

[0006] Therefore, this application proposes a protective device for glass substrate grinding. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] To address the technical problems in the background art, the following protective device for glass substrate grinding is provided:

[0039] Combination Figures 1-7 As shown, the present invention provides a protective device for glass substrate grinding, including a machine base 4 and a protective cover 1. The machine base 4 is provided with a lifting port 41, and the protective cover 1 is slidably installed in the lifting port 41. A lifting component 2 is fixedly installed at the bottom of the machine base 4, and the output end of the lifting component 2 is used to drive the protective cover 1 to lift. A baffle 5 is movably installed on the front end face of the protective cover 1, and an internal groove 12 is provided on the inner side of the protective cover 1. The protective cover 1 is retracted into the baffle 5 through the internal groove 12. A latex glove 9 is installed on the inner side of the baffle 5. A cooling component 6 extending into the protective cover 1 is assembled on the back of the protective cover 1, and the working end of the cooling component 6 extends into the protective cover 1. A cleaning component 8 is assembled on the top of the protective cover 1, and storage components 7 are installed on both sides inside the protective cover 1.

[0040] The cooling component 6 includes a mounting cavity 61 and a cooling component 62. The back of the protective cover 1 is provided with a mounting port 13. The mounting cavity 61, which communicates with the mounting port 13, is fixedly installed on the back of the protective cover 1. The cooling component 62 is assembled inside the mounting cavity 61.

[0041] The storage component 7 includes a storage box 71 and a storage component 72. The storage box 71 is installed on both sides of the protective cover 1, and the storage component 72 is assembled inside the storage box 71.

[0042] The cleaning component 8 includes a drive component 81 and a cleaning component 82. The drive component 81 is mounted on the top of the protective cover 1, and the cleaning component 82 is installed on the drive end of the drive component 81. The cleaning component 82 is used to clean the top of the machine base 4.

[0043] In the above scheme:

[0044] The interaction between the protective cover 1 and the baffle 5 effectively protects and isolates the grinding area of ​​the grinding equipment, thus preventing glass fragments and grinding fluid from splashing and providing effective protection to the outside.

[0045] By setting latex gloves 9 on baffle 5, the equipment can perform non-contact extraction after grinding, and can be stored and placed in conjunction with storage component 7. In this way, the ground glass substrate will not carry out slurry, ensuring the cleanliness of the working environment.

[0046] The cooling component 6 works in conjunction with the protective cover 1 to ensure that the equipment can be cooled in stages during grinding, thus preventing the grinding components from getting too hot during the protection period.

[0047] The cleaning component 8 allows for rapid cleaning of the grinding area without removing the protective gear. This not only ensures the cleanliness of the processing area but also eliminates the need for manual cleaning and facilitates quick material loading, thus improving the work process.

[0048] During this process, the personnel place the glass substrate to be ground in the grinding area of ​​the equipment, and the lifting component 2 can drive the protective cover 1 to lift and lower, causing the protective cover 1 to enter or exit the working state.

[0049] During operation, the protective cover 1 is lifted, and the personnel manually flip the baffle 5 outward from the built-in groove 12 to form a complete enclosure with the protective cover 1. The baffle 5 can be opened and closed, allowing the device to be combined for protection and facilitating personnel to load materials and perform subsequent operations. After the equipment finishes grinding, the personnel can use latex gloves 9 to remove the glass substrate and place it in the storage box 71 inside the storage component 7 for arrangement and collection. This prevents liquid on the glass substrate from contaminating the outside. The grinding area of ​​the grinding equipment can then be cleaned by the interaction of the drive component 81 and the cleaning component 82. Finally, the baffle 5 can be opened to remove and replace the stored storage component 7, and then replenishment processing can be carried out.

[0050] Example 2

[0051] like Figure 1 and Figure 7 As shown, based on the above embodiments, this embodiment further provides the following:

[0052] In this embodiment, rubber blocking sheets 3 are fixedly installed at the bottom of both the protective cover 1 and the baffle 5. When the protective cover 1 and the baffle 5 are protecting, the rubber blocking sheets 3 block the lifting port 41, and the protective cover 1 and the baffle 5 are transparent.

[0053] During this period, when the protective cover 1 and the baffle 5 are raised to the protective state, the rubber blocking plate 3 simultaneously reaches the position of the lifting port 41 and blocks the lifting port 41. In this way, when cleaning, the liquid will be blocked by the rubber blocking plate 3, preventing it from leaking out from the lifting port 41.

[0054] A flow channel is provided on the front side of the top of the machine 4, which is used to discharge the grinding slurry from the top surface of the machine 4.

[0055] During this period, personnel can observe the actual processing progress inside the enclosure 1 from the outside, and the grinding waste liquid generated during processing and cleaning will be discharged from the guide channel.

[0056] In this embodiment, a hinge shaft 11 is installed on the protective cover 1, and the protective cover 1 is movably connected to the baffle 5 through the hinge shaft 11. The baffle 5 is provided with a probe 51, and a glove mounting part 91 is installed at the inner end of the probe 51. The baffle 5 is installed with the latex glove 9 through the glove mounting part 91.

[0057] During daily operations, personnel can use the hinge shaft 11 to open and close the baffle 5 on the protective cover 1, which can provide combined protection and facilitate personnel to load materials and perform subsequent operations.

[0058] When retrieving materials, personnel can insert the probe 51 into the interior of the cover and pass through the glove mounting piece 91 to connect with the latex glove 9 for wearing. After use, personnel can remove the latex glove 9 through the glove mounting piece 91 for easy replacement.

[0059] In this embodiment, the lifting assembly 2 includes a first threaded rod 21, a first motor 22, and a guide plate 23. The guide plate 23 is fixedly installed on the back of the protective cover 1 and is slidably connected to the machine base 4. The first motor 22 is fixedly installed on the bottom of the machine base 4. The output end of the first motor 22 is connected to the first threaded rod 21, and the first threaded rod 21 extends into the guide plate 23 and is engaged by threads.

[0060] During this period, the lifting component 2 can drive the protective cover 1 to lift and lower, causing the protective cover 1 to enter or exit the working state.

[0061] Start the first motor 22, which drives the first threaded rod 21 to rotate, causing the first threaded rod 21 to drive the guide plate 23. Since the guide plate 23 is limited by the machine base 4, the guide plate 23 will rise and fall on the machine base 4, causing the protective cover 1 to reach the required working state.

[0062] In this embodiment, the cooling component 62 includes a second threaded rod 621, a second motor 622, a connecting seat 623, a connector 624, an elastic hose 625, a hollow square rod 626, a spray head 627, and a third motor 628. The second threaded rod 621 is installed inside the mounting cavity 61. The second motor 622, which is connected to the second threaded rod 621, is fixedly installed on the top of the mounting cavity 61. The connecting seat 623 is fitted on the second threaded rod 621 and is slidably connected to the mounting cavity 61. The connector 624 is movably installed on the connecting seat 623. The third motor 628 is fixedly installed on the connecting seat 623, and the output shaft of the third motor 628 is connected to the movable end of the connector 624. The hollow square rod 626 is installed at the outer end of the connector 624. The front end of the hollow square rod 626 is connected to the spray head 627, and the rear end is connected to the elastic hose 625.

[0063] During this period, the intermittent heat dissipation of the cooling component 62 enables the spraying of cooling medium on the grinding components of the grinding equipment to assist in heat dissipation, reduce the temperature of the grinding components, and reduce thermal stress through appropriate cooling, thereby improving the surface smoothness and flatness of the glass substrate.

[0064] During this process, the third motor 628 drives the second threaded rod 621 to rotate, which in turn drives the connecting seat 623 to descend. Once the connecting seat 623 reaches the bottom, the second motor 622 is restarted. The second motor 622 drives the connecting head 624 to flip it over, causing the hollow square rod 626 to flip down from the mounting cavity 61. This allows the spray head 627 to face the grinding component. At this time, the external cooling medium enters the elastic hose 625 and is guided into the spray head 627 through the hollow square rod 626 for spraying. The spraying method is intermittent spraying.

[0065] It should be noted that the spray head 627 uses intermittent spraying, and the spray target is the grinding disc of the grinding equipment. By spraying the grinding disc with cooling medium, the temperature on the grinding disc is reduced. This can prevent cold water from entering the grinding tank and ensure that even if a small amount of water is mixed in, it will not significantly affect the grinding effect.

[0066] Example 3

[0067] like Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0068] In this embodiment, the storage component 72 includes a limiting port 721, a limiting plate 722, and a mesh plate 723. The mesh plate 723 is detachably installed at the lower port of the storage box 71. The limiting plate 722 is fixedly installed in the storage box 71 above the mesh plate 723, and the limiting ports 721 are evenly distributed on the limiting plate 722.

[0069] During this process, the personnel take the ground glass substrate out of the equipment and insert it into the limiting port 721 of the limiting plate 722. The bottom of the glass substrate is supported by the mesh plate 723.

[0070] The limiting plate 722 ensures that the glass substrates are evenly arranged. The purpose is to allow the polishing liquid on the glass substrates to drain out, so that personnel will not get contaminated when handling them, thus ensuring the cleanliness of the working environment.

[0071] During recycling, personnel directly remove the storage box 71, then remove the ground glass substrate, and pour out the receiving medium inside the storage box 71.

[0072] The inner wall of the built-in slot 12 is provided with an insertion interface extending into the protective cover 1. Three sets of plug-in plates 712 are fixedly installed on the storage box 71, and the plug-in plates 712 are mated with the insertion interface. Both sides of the storage box 71 are provided with handles 711.

[0073] By combining the above, when installing or placing the storage box 71, the operator can insert the storage box 71 into the interface through the three sets of plug plates 712 to complete the docking between the storage box 71 and the protective cover 1. In this way, after the equipment is finished grinding, the operator can extract the ground glass substrate and quickly place it into the storage box 71, so that the liquid on the glass substrate will not contaminate the outside.

[0074] In this embodiment, the driving component 81 includes a mounting base 811, a fourth motor 812, a guide block 813, a third threaded rod 814, and a guide rod 815. Mounting bases 811 are fixedly installed on both sides of the top of the storage box 1. The protective cover 1 is equipped with the third threaded rod 814 and the guide rod 815 respectively through the mounting bases 811. The fourth motor 812 for driving the third threaded rod 814 is fixedly installed on the mounting base 811. The guide block 813 is fitted on the third threaded rod 814 and the guide rod 815. The two ends of the cleaning component 82 are fixedly connected to the guide block 813.

[0075] The cleaning component 82 includes a mounting plate 821, a support frame 822, a spray head 823, a guide rod 824, a rubber scraper 825, and a fifth motor 826. The two ends of the mounting plate 821 are fixedly connected to the guide block 813. The support frame 822 is movably mounted on both sides inside the mounting plate 821, and the support frame 822 is right-angled. The fifth motor 826 is fixedly mounted on the back of the mounting plate 821. The output end of the fifth motor 826 is installed and connected to the support frame 822. The guide rod 824 and the rubber scraper 825 are fixedly mounted on the corresponding surfaces of the support frame 822, and the spray heads 823 are evenly distributed on the guide rod 824.

[0076] After the equipment finishes grinding, the grinding area of ​​the grinding equipment can be cleaned by the cooperation of the drive component 81 and the cleaning component 82. This not only ensures the cleanliness of the processing area, eliminating the need for manual cleaning, but also facilitates quick loading of materials and improves the work process.

[0077] During routine operations, the fifth motor 826 is started, which drives the support frame 822 to rotate, causing the support frame 822 to tilt downwards. Then, external cleaning medium is introduced into the guide rod 824 to rinse the grinding slurry in the protected area. The fourth motor 812 is then started, and its output drives the third threaded rod 814 to rotate, thereby driving the guide block 813. This allows the mounting plate 821 to move linearly through the guide block 813, thus enabling the cleaning of the protected area. After cleaning, the personnel can place the subsequent glass substrate.

[0078] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
