Description

Technical Field

[0001] The utility model relates to the field of liquid crystal glass substrate production and manufacturing, in particular to an auxiliary positioning device for a liquid crystal glass substrate. Background Art

[0002] In the production process of liquid crystal glass substrates, the liquid crystal glass substrates need to be positioned on a conveyor brush belt before being put into processing, and then conveyed to downstream processing equipment to ensure processing accuracy.

[0003] The usual practice is to place the LCD glass substrate directly on the brush belt and push the glass edges on four sides for positioning. Due to the presence of fine glass powder on the brush belt, the LCD glass substrate is prone to slight scratches during the positioning process, affecting product quality. Utility Model Content

[0004] The utility model aims to provide an auxiliary positioning device for a liquid crystal glass substrate, which effectively solves the problem that the liquid crystal glass substrate is easily scratched by the brush during the positioning process when it is placed on a brush belt.

[0005] The technical solution of the utility model is as follows:

[0006] An auxiliary positioning device for a liquid crystal glass substrate comprises a platform body, a plurality of positioning substrates are arranged on the top of the platform body, a through circular hole is arranged in the middle of the positioning substrate, a brush belt is arranged on the top of the positioning substrate, a glass substrate is placed on the top of the brush belt, a lifting cylinder is arranged on the top of the platform body, an air flotation plate is connected to the telescopic rod of the lifting cylinder, a plurality of blowing holes are opened on the top of the air flotation plate, an air inlet pipe extending to the outside is arranged inside the air flotation plate, the air flotation plate is located in the through circular hole, and a glass positioning mechanism located around the glass substrate is arranged on the top of the platform body.

[0007] Furthermore, four corners of the bottom of the positioning substrate are provided with support columns vertically connected to the platform body, and the number of the positioning substrates on the platform body is not less than two.

[0008] Furthermore, the air intake pipe is provided with an air pressure regulating valve connected thereto.

[0009] Furthermore, the glass positioning mechanism includes a mounting strip, a sliding plate, a positioning block, a wheel groove, and a positioning wheel. The mounting strip is symmetrically fixedly installed on the top of the platform body. A sliding plate is provided between the tops of the two mounting strips. The sliding plate is movably installed on the mounting strip. The positioning block is symmetrically fixedly installed on the top of the sliding plate.

[0010] Furthermore, the wheel groove is located on the positioning block, and the opening of the wheel groove faces the glass substrate, and the positioning wheel is symmetrically and movably installed in each wheel groove.

[0011] Furthermore, the glass positioning mechanism also includes a servo motor, a screw rod, and a slider. The screw rod is arranged below the sliding plate, the slider is slidably connected to the screw rod, the top of the slider is fixedly connected to the sliding plate, the servo motor is fixedly connected to the platform body, and the output shaft of the servo motor is connected to the screw rod.

[0012] The advantages of the utility model are:

[0013] 1. The utility model provides an air flotation plate and a lifting cylinder. The lifting cylinder lifts the glass and blows air to lift the glass substrate, so that the glass substrate is positioned away from the brush platform. Compared with the traditional method of directly placing the glass on the brush block for positioning, the utility model effectively avoids the situation where the glass substrate is scratched due to the back-and-forth friction between the glass and the brush, and effectively protects the glass substrate.

[0014] 2. The utility model provides an air pressure regulating valve on the air inlet pipe, which can adjust the air volume of the air inlet pipe, thereby adjusting the glass blowing height, and can be adjusted according to the required height, thereby improving the flexibility of the device.

[0015] 3. The utility model lifts up the glass substrate by arranging different numbers of blowing holes on the air flotation plate, which has a lower cost than using all air flotation platforms to float the glass. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A brush belt 4 is provided on the top of the positioning substrate 2, and a glass substrate 5 is placed on the top of the brush belt 4. The brush belt 4 is arranged so that the glass substrate 5 can be placed on it before and after positioning, and the glass substrate 5 is kept on a plane.

[0024] A lifting cylinder 6 is provided on the top of the platform body 1, and the telescopic rod of the lifting cylinder 6 is connected to an air flotation plate 7. A plurality of blowing holes 8 are provided on the top of the air flotation plate 7. The interior of the air flotation plate 7 is hollow, and the blowing holes 8 are provided on the top plate of the air flotation plate 7. After the gas enters the interior of the air flotation plate 7, it will be blown out from the blowing holes 8 on the top.

[0025] An air intake pipe 9 extending to the outside is provided inside the air flotation disk 7, and the other end of the air intake pipe 9 is connected to an air intake device, through which air is supplied.

[0026] The air floating plate 7 is located in the through circular hole 3 , and a glass positioning mechanism is provided on the top of the platform body 1 around the glass substrate 5 .

[0027] Support columns vertically connected to the platform body 1 are provided at the four corners of the bottom of the positioning substrate 2 . The number of positioning substrates 2 on the platform body 1 is not less than two, so that the glass substrate 5 maintains a certain stability.

[0028] An air pressure regulating valve 10 is connected to the air inlet pipe 9, and the air pressure regulating valve 10 can adjust the air volume of the air inlet pipe 9, thereby adjusting the glass blowing height, and can be adjusted according to the required height.

[0029] The glass positioning mechanism includes a mounting bar 11, a sliding plate 12, a positioning block 13, a wheel groove 14, and a positioning wheel 15. The mounting bar 11 is symmetrically fixedly installed on the top of the platform body 1. A sliding plate 12 is provided between the tops of the two mounting bars 11. The sliding plate 12 is movably installed on the mounting bar 11. The positioning block 13 is symmetrically fixedly installed on the top of the sliding plate 12. The sliding plate 12 is slidably installed on the mounting bar 11. Under the driving force, the sliding plate 12 can be close to the edge of the glass substrate 5.

[0030] The wheel groove 14 is located on the positioning block 13, and the opening of the wheel groove 14 faces the glass substrate 5. The positioning wheel 15 is symmetrically and movably installed in each wheel groove 14. When the positioning block 13 moves to a certain extent, the wheel wall of the positioning wheel 15 will contact the edge of the glass substrate 5 to position the glass substrate 5.

[0031] The glass positioning mechanism also includes a servo motor 16, a screw rod 17, and a slider 18. The screw rod 17 is arranged below the sliding plate 12. The slider 18 is slidably connected to the screw rod 17. The top of the slider 18 is fixedly connected to the sliding plate 12. The servo motor 16 is fixedly connected to the platform body 1.

[0032] Detailed usage and effects of the above embodiments:

[0033] When the glass substrate 5 is transferred to the platform body 1, in the initial state, the glass substrate 5 is placed on the brush belt 4 on the positioning substrate 2, and the brush belt 4 supports the glass substrate 5. When positioning begins, the lifting cylinder 6 drives the telescopic rod to make the air flotation plate 7 rise in the through-hole 3. At the same time, the external air intake device is started to transport the gas to the inside of the air flotation plate 7 through the air intake pipe 9. In the process of lifting the glass substrate 5, the gas acts on the bottom of the glass substrate 5 through the blowing holes 8 on the air flotation plate 7, so that the glass substrate 5 will slowly float up, and the floating height can be adjusted by the regulating valve.

[0034] The servo motor 16 is started, driving the screw rod 17 to rotate, so that the slider 18 moves forward, and the sliding plate 12 moves on the mounting strip 11 toward the direction of the glass substrate 5. The top of the sliding plate 12 is fixedly connected with a positioning block 13, and the positioning block 13 is provided with a positioning wheel 15. Finally, the wheel wall of the positioning wheel 15 will contact the edge of the glass substrate 5, thereby completing the positioning of the glass substrate 5. After the positioning is completed, the positioning wheel 15 moves backward, and the external air intake device no longer intakes air, so that the blowing hole 8 no longer blows air, and the glass substrate 5 returns to the air floating plate 7. The lifting cylinder 6 drives the air floating plate 7 to descend, so that the glass substrate 5 returns to the brush belt 4.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
