Description

Technical Field

[0001] This utility model relates to the field of liquid crystal glass substrate processing and manufacturing technology, and in particular to a liquid crystal glass substrate conveying device. Background Technology

[0002] In the production process of LCD glass substrates, glass conveying is an indispensable part of glass processing. During the precision cutting process of LCD glass substrates, brush belts are mainly used for conveying to ensure the stability of the glass. However, the brush belts have many brushes on their surface, which easily accumulate dirt, glass powder, etc., which affect the quality of the glass during the conveying process.

[0003] Traditional cleaning methods require machine shutdown and manual wiping, which not only reduces production line uptime but also poses safety hazards. Current technology lacks a device that can automatically clean the brush belt to solve the above technical problems. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a liquid crystal glass substrate conveying device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A liquid crystal glass substrate conveying device, characterized in that it comprises:

[0007] Base;

[0008] The motor is mounted on the base and is connected to the conveying assembly to transport the liquid crystal glass substrate.

[0009] Multiple telescopic columns are arranged vertically and correspond one-to-one with multiple brush belts on the conveyor assembly. Each telescopic column is equipped with a cleaning component at its top.

[0010] The liquid supply assembly includes an alcohol tank and a peristaltic pump. One end of the peristaltic pump is connected to the alcohol tank via a hose, and the other end of the peristaltic pump is connected to multiple guide tubes, the ends of which extend to the top of the corresponding telescopic column.

[0011] Preferably, the conveying assembly includes a first conveyor wheel, a second conveyor wheel, and multiple brush belts. The first conveyor wheel and the second conveyor wheel are arranged in parallel. A motor is connected to the first conveyor wheel / the second conveyor wheel. The first conveyor wheel and the second conveyor wheel are connected by multiple brush belts.

[0012] Preferably, the cleaning component includes a mounting base detachably connected to the top of the telescopic column and a cleaning cotton fixed to the mounting base.

[0013] Preferably, the top of the cleaning cotton is inclined upward along the conveying direction of the brush belt, and the cleaning cotton and the guide tube are arranged in sequence along the conveying direction of the brush belt.

[0014] Preferably, when the telescopic column drives the cleaning cotton to rise so that the cleaning cotton contacts the brush belt, the contact pressure is 0.2 N / cm. 2 -0.5N / cm 2 .

[0015] Preferably, the end of the guide tube is provided with an atomizing nozzle, and the spray direction of the atomizing nozzle is arranged parallel to the inclined direction of the tip of the cleaning cotton.

[0016] Preferably, the cleaning cotton is made of a gradient density composite material, including a bottom layer of rigid nylon fiber, a middle layer of polyester sponge adsorption layer and a surface layer of microfiber braided layer. The diameter of the fiber in the surface layer gradually changes from 10μm to 2μm in segments, and the direction of the gradient is opposite to the direction of movement of the brush belt.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Compared with existing technologies, by setting a liquid supply component and a cleaning component at the bottom of the conveying component, automatic cleaning of the brush belt can be achieved without stopping the machine, which improves the production efficiency of LCD glass substrates. By keeping the angle of the atomizing nozzle consistent with the tilt angle of the cleaning cotton, the cleaning cotton can be evenly wetted and the residual impurities on the cleaning cotton can be reduced, thereby improving the cleaning effect of the brush belt.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-3 As shown, this embodiment provides a liquid crystal glass substrate conveying device, including:

[0025] Base 1;

[0026] Motor 2 is mounted on base 1 and connected to conveying assembly 3 to convey the liquid crystal glass substrate;

[0027] Multiple telescopic columns 4 are arranged vertically and correspond one-to-one with multiple brush belts 33 on the conveying component 3. A cleaning component 5 is installed at the top of each telescopic column 4.

[0028] The liquid supply assembly includes an alcohol tank 6 and a peristaltic pump 7. One end of the peristaltic pump 7 is connected to the alcohol tank 6 via a hose, and the other end of the peristaltic pump 7 is connected to multiple guide tubes 9. The ends of the guide tubes 9 extend to the top of the corresponding telescopic column 4.

[0029] Overall, when the motor 2 drives the conveying component 3 to continuously convey the liquid crystal glass substrate, in order to ensure the cleaning effect of the brush belt 33 and avoid the glass powder accumulated on the brush belt 33 from scratching the surface of the liquid crystal glass substrate, one minute before the telescopic column 4 rises, the operator controls and starts the peristaltic pump 7 through the PLC controller 8. The alcohol in the alcohol tank 6 flows through the hose and is finally sprayed out from the guide pipe 9 to wet the cleaning component 5. One minute later, the telescopic column 4 is controlled to rise through the PLC controller 8 until the cleaning component 5 contacts the lower surface of the brush belt 33. After the cleaning component 5 contacts the brush belt 33, the conveying component 3 continues to operate. Through the relative movement between the two, the cleaning treatment of the brush belt 33 can be achieved.

[0030] Due to limited space, in order to ensure stable pressure of the brush belt 33 during the transportation of the liquid crystal glass substrate, multiple telescopic columns 4 are started in stages to ensure that at least one telescopic column 4 is in contact with its corresponding brush belt 33, thereby reducing the load on the entire device. The timed start of the telescopic columns 4 is realized through the timing module in the PLC controller 8, and the telescopic columns 4 are switched every three hours.

[0031] like Figures 1-3 As shown, in this embodiment, the conveying assembly 3 includes a first conveying wheel 31, a second conveying wheel 32, and multiple brush belts 33. The first conveying wheel 31 and the second conveying wheel 32 are arranged in parallel. The motor 2 is connected to the first conveying wheel 31 / the second conveying wheel 32. The first conveying wheel 31 and the second conveying wheel 32 are connected by multiple brush belts 33.

[0032] Specifically, the first conveyor wheel 31 and the second conveyor wheel 32 are driven to rotate by the motor 2. Since the first conveyor wheel 31 and the second conveyor wheel 32 are connected by multiple brush belts 33, the multiple brush belts 33 can rotate synchronously and complete the conveying of the liquid crystal glass substrate.

[0033] like Figure 2 As shown, in this embodiment, the cleaning component 5 includes a mounting base detachably connected to the top of the telescopic column 4 and a cleaning cotton fixed to the mounting base.

[0034] By enabling a detachable connection between the mounting base and the telescopic column 4, the cleaning cotton can be easily replaced.

[0035] like Figure 2 As shown, in this embodiment, the top of the cleaning cotton is inclined upward along the conveying direction of the brush belt 33, and the cleaning cotton and the guide tube 9 are arranged sequentially in the conveying direction of the brush belt 33.

[0036] Specifically, the cleaning cotton is inclined upward along the conveying direction of the brush belt 33, so that the inclined direction is opposite to the movement direction of the brush belt 33, forming a "countercurrent cleaning" effect. While effectively enhancing the scraping force, the inclined setting of the cleaning cotton also allows the glass powder to fall along the inclined direction due to its gravitational inertia, avoiding glass powder residue on the cleaning cotton, thus extending the service life of the brush belt 33 while ensuring cleaning efficiency.

[0037] In addition to the above technical solutions, this utility model also provides another embodiment, which differs from the above embodiments in that: a lint-free cloth is used instead of cleaning cotton to clean the brush belt 33. Of course, designers can choose different cleaning components 5 according to the actual situation, and there are no restrictions here.

[0038] like Figures 2-3 As shown, in this embodiment, when the telescopic column 4 drives the cleaning cotton to rise so that the cleaning cotton contacts the brush belt 33, the contact pressure is 0.2 N / cm. 2 -0.5N / cm 2 .

[0039] Specifically, when the telescopic column 4 rises to bring the cleaning cotton into contact with the brush belt 33, the pressure sensor inside the PLC controller 8 sets the contact pressure between the cleaning cotton and the brush belt 33 to 0.2 N / cm. 2 -0.5N / cm 2 This avoids excessive pressure that could cause excessive wear on the cleaning cotton / brush belt 33, thereby improving the overall service life of the device.

[0040] like Figure 2As shown, in this embodiment, the end of the guide tube 9 is provided with an atomizing nozzle, and the spray direction of the atomizing nozzle is arranged parallel to the tilt direction of the top of the cleaning cotton.

[0041] By setting an atomizing nozzle at the end of the guide tube 9, and with the spray direction of the atomizing nozzle parallel to the inclined surface of the top of the cleaning cotton, an alcohol mist can cover the cleaning area, reducing droplet splashing. At the same time, the sprayed alcohol liquid can remove a small amount of glass powder residue on the cleaning cotton.

[0042] like Figures 2-3 As shown, in this embodiment, the cleaning cotton is made of a gradient density composite material, including a bottom layer of rigid nylon fiber, a middle layer of polyester sponge adsorption layer and a surface layer of microfiber braided layer. The fiber diameter of the surface layer gradually changes from 10μm to 2μm in segments, and the direction of the gradient is opposite to the direction of movement of the brush belt 33.

[0043] By using a gradient density composite material, while ensuring the rigid support of the cleaning cotton, the middle adsorption layer can store alcohol and release it evenly, thereby improving the cleaning effect of the brush band 33.

[0044] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
