Abstract
Description
Technical Field
[0001] This utility model relates to the field of display glass processing technology, and in particular to a display glass pre-polishing and thinning device. Background Technology
[0002] With the development of information technology and the upgrading of consumer demand, existing devices such as TV displays are becoming increasingly thinner and lighter. This trend requires that the glass substrate of the display panel must be thinner to reduce weight and size, thus requiring the use of display glass pre-polishing and thinning equipment.
[0003] Mechanical grinding is commonly used when thinning display glass. This method is not only inefficient but also easily damages the glass surface, affecting the thinning effect and product quality. Furthermore, existing equipment requires manual operation during the thinning process, which is labor-intensive and poses certain safety hazards. To solve the above problems, this application proposes a display glass pre-polishing and thinning device. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pre-polishing and thinning device for display glass. This device uses hydrofluoric acid solution to acidify one side of the glass, achieving thinning. It also uses an adsorption mechanism to fix the glass and a motor to drive the glass to move up and down, replacing manual operation and ensuring the safety of workers.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A display glass pre-polishing and thinning device includes a thinning box. Two vertical plates are fixedly connected to the top of the thinning box, and a top plate is fixedly connected to both vertical plates. A motor is fixedly connected to the side wall of the right vertical plate. A double worm gear is fixedly connected to the output end of the motor. The double worm gear passes through the two vertical plates and is rotatably connected to them. The double worm gear meshes with two worm wheels. Each worm wheel has a threaded rod fixedly connected to it on its axis. Both threaded rods are rotatably connected to the bottom of the top plate. A hollow column is threadedly connected to the outer wall of each threaded rod. A hollow plate is fixedly connected to both hollow columns. A display glass body is located below the hollow plate. An adsorption mechanism is provided between the hollow plate and the display glass body. Four adjustment mechanisms are provided at the bottom of the thinning box.
[0007] Preferably, the adsorption mechanism includes a T-shaped screw that passes through and is rotatably connected to the hollow plate. The outer wall of the T-shaped screw is fitted with a lifting plate that is threadedly connected to it. The bottom of the lifting plate is fixedly connected to four connecting rods. The bottom of the hollow plate is fixedly connected to four suction cups. The bottom of each connecting rod is fixedly connected to a piston. The four pistons are respectively located inside the suction cups and are slidably and sealingly connected to their inner walls.
[0008] Preferably, the adjustment mechanism includes a fixing screw fixedly connected to the bottom of the thinning box, the outer wall of the fixing screw is fitted with a hollow leg threadedly connected thereto, and the bottom of the hollow leg is provided with anti-slip texture.
[0009] Preferably, the double worm gear consists of two identical worm gears coaxially fixedly connected, and the two worm gears respectively mesh with their corresponding worm wheels.
[0010] Preferably, the outer wall of the hollow plate is fixedly connected to two symmetrically arranged fixing blocks, and L-shaped rods are fixedly connected to the opposite ends of the two upright plates. The two L-shaped rods pass through the corresponding fixing blocks and are slidably connected to them.
[0011] Preferably, a discharge hopper is fixedly connected to the side wall of the thinning box, and a valve is installed on the outer wall of the discharge hopper.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. The operator holds the hollow leg and rotates it to move the hollow leg up and down. By adjusting the height of the four hollow legs, the device is kept horizontal, making the device stable on the ground and improving the subsequent thinning effect.
[0014] 2. The operator then holds the T-shaped screw and rotates it to move the lifting plate upward. The upward movement of the lifting plate moves the four connecting rods and piston upward. The piston slides inside the suction cup, which increases the space below the piston and creates negative pressure. This allows the four suction cups to adhere and fix the display glass, ensuring that the display glass is firmly attached and fixed, thus completing the installation and fixing of the display glass.
[0015] 3. The motor output drives the double worm gear, two worm wheels, and threaded rod to rotate, causing the hollow column, hollow plate, and adsorbed display glass to move downwards. The L-shaped rod and the fixed block work together to stabilize the lifting and lowering of the display glass until the bottom of the display glass is immersed in the hydrofluoric acid solution. The hydrofluoric acid solution can be used to thin the bottom of the display glass.
[0016] In summary, hydrofluoric acid solution can be used to acidify one side of the glass, achieving thinner glass processing. The glass can be fixed by an adsorption mechanism, and the glass can be lifted and moved by a motor, replacing manual operation and ensuring the safety of workers. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figures 1-2 A display glass pre-polishing and thinning device includes a thinning chamber 1. The inner wall of the thinning chamber 1 is provided with a protective layer (copper, iron, nickel, silver, platinum, etc. alloy plating) and can contain hydrofluoric acid solution. Two vertical plates 2 are fixedly connected to the top of the thinning chamber 1. The two vertical plates 2 are jointly fixedly connected to a top plate 3. A motor 4 is fixedly connected to the side wall of the right vertical plate 2. A double worm gear 5 is fixedly connected to the output end of the motor 4. The double worm gear 5 passes through the two vertical plates 2 and is rotatably connected to them. The double worm gear 5 meshes with two worm wheels 6. The double worm gear 5 is made up of two identical worms coaxially fixedly connected. The two worms mesh with their corresponding worm wheels 6 respectively. Each worm wheel 6 has a threaded rod 7 that is coaxially fixedly connected to it. Both threaded rods 7 are connected to the bottom of the top plate 3. The rotating connection is provided, and each threaded rod 7 has a hollow column 8 threadedly connected to it on its outer wall. Two hollow columns 8 are fixedly connected to a hollow plate 9. Two symmetrically arranged fixing blocks 11 are fixedly connected to the outer wall of the hollow plate 9. L-shaped rods 10 are fixedly connected to the opposite ends of the two upright plates 2. The two L-shaped rods 10 pass through the corresponding fixing blocks 11 and are slidably connected to them. The cooperation between the L-shaped rods 10 and the fixing blocks 11 can make the hollow plate 9 rise and fall stably. The hollow plate 9 can be moved up and down by the forward and reverse rotation of the motor 4. The bottom of the glass is immersed in the hydrofluoric acid solution to thin the glass (by using hydrofluoric acid and other chemicals to react with the silicon dioxide on the glass surface, the glass is dissolved and thinned by chemical etching).
[0022] A display glass body is located below the hollow panel 9. An adsorption mechanism is provided between the hollow panel 9 and the display glass body. The adsorption mechanism includes a T-shaped screw 12 that passes through the hollow panel 9 and is rotatably connected to it. A lifting plate 13 that is threadedly connected to the outer wall of the T-shaped screw 12 is sleeved on it. Four connecting rods 14 are fixedly connected to the bottom of the lifting plate 13. Four suction cups 16 are fixedly connected to the bottom of the hollow panel 9. A piston 15 is fixedly connected to the bottom of each connecting rod 14. The four pistons 15 are located in the suction cups 16 and are slidably connected to their inner walls. The suction cups 16 include a hollow tube and a rubber disc, which are connected to each other. The pistons 15 can slide in the hollow tube. The glass can be adsorbed and fixed by the four suction cups 16, ensuring the stability of the glass.
[0023] The bottom of the thinning box 1 is equipped with four adjustment mechanisms. Each adjustment mechanism includes a fixing screw that is fixedly connected to the bottom of the thinning box 1. The outer wall of the fixing screw is fitted with a hollow leg that is threadedly connected to it. By rotating the hollow leg, it can be raised and lowered, which can make the device horizontal and achieve a good thinning effect on the glass. The bottom of the hollow leg is provided with anti-slip texture. The side wall of the thinning box 1 is fixedly connected to a discharge hopper 17, and a valve is installed on the outer wall of the discharge hopper 17.
[0024] In this invention, the operator holds the hollow legs and rotates them to move them up and down. By adjusting the height of the four hollow legs, the device is kept horizontal, ensuring stable installation on the ground and facilitating subsequent thinning. The operator pours hydrofluoric acid solution into the thinning tank 1, then places the glass to be thinned under the hollow plate 9, ensuring the bottoms of the four suction cups 16 are pressed against the top of the display glass. The operator then holds and rotates the T-screw 12, causing the lifting plate 13 to move upward. This upward movement of the lifting plate 13 causes the four connecting rods 14 and the piston 15 to move upward. The piston 15 slides within the suction cups 16, creating a negative pressure that allows the four suction cups 16 to adhere and fix the display glass, ensuring a firm hold and completing the installation of the display glass. Fix; start motor 4, which drives the double worm gear 5, two worm wheels 6, and threaded rod 7 to rotate through the output end of motor 4, causing the hollow column 8, hollow plate 9, and adsorbed display glass to move downward. The L-shaped rod 10 and the fixing block 11 can stabilize the lifting and lowering of the display glass until the bottom of the display glass is immersed in the hydrofluoric acid solution. The hydrofluoric acid solution can thin the bottom of the display glass (by using hydrofluoric acid and other chemicals to react with the silicon dioxide on the glass surface, the glass is dissolved and thinned through chemical etching). After thinning, start motor 4 to rotate its output end in reverse, causing the adsorbed display glass to move upward a certain distance. The operator holds the T-shaped screw 12 and rotates it in reverse to move the four pistons 15 downward, which can remove the glass and complete the glass thinning operation, which is convenient for subsequent polishing.
[0025] This invention utilizes a hydrofluoric acid solution to acidify one side of the glass, an adsorption mechanism to fix the glass in place, and a motor to drive the glass to move up and down, replacing manual operation. This solves the problems of existing technologies that typically use mechanical grinding for thinning display glass. This method is not only inefficient but also prone to damaging the glass surface, affecting the thinning effect and product quality. Furthermore, existing equipment requires manual operation during the thinning process, which is labor-intensive and poses certain safety hazards.
