Description

Technical Field

[0001] This utility model relates to the field of liquid crystal glass substrate cutting technology, and specifically to a dust removal device for liquid crystal glass substrate cutting. Background Technology

[0002] Liquid crystal glass substrates are an important component of liquid crystal flat panel displays. In the production of liquid crystal glass substrates, it is necessary to cut the glass substrates into appropriate sizes. After searching, the existing technology (announcement number: CN202420975952.4) for cutting dust removal device describes that "by setting a first chamber in the support base and introducing electrostatic dust removal airflow into the first chamber, the electrostatic dust removal airflow can eliminate the static electricity of the dust in time, effectively and timely removing the adhesion of dust to the surface of the glass substrate. At the same time, the dust is sucked up and discharged by the dust collection component, and a negative pressure is formed in the first chamber, which can effectively reduce the dust from escaping to the outside of the first chamber and eliminate the contamination of the glass substrate by the dust, thereby significantly improving the quality of the glass substrate and the cutting yield." However, the existing technology only uses electrostatic suction to remove glass dust, which results in a large amount of dust accumulation, requiring frequent shutdowns for cleaning, leading to low dust removal efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a dust removal device for cutting liquid crystal glass substrates is provided to solve the problem that the dust removal efficiency is low because the amount of dust accumulated is large and frequent shutdowns are required to clean the dust when removing glass dust by electrostatic attraction alone.

[0004] To achieve the above objectives, a dust removal device for cutting liquid crystal glass substrates is provided, comprising: a cutting dustproof cover, wherein a cutting head is sleeved and connected to the upper end of the cutting dustproof cover.

[0005] A dust suction port is provided on the inner wall of the right side of the cutting dustproof cover. The right end of the dust suction port is connected to a water curtain dust collector via a dust conveying pipe. A sealing cover is attached to the upper end of the water curtain dust collector. A stainless steel water curtain plate is fixed to the middle of the lower end face of the sealing cover. Separation mesh cylinders are distributed at the lower end of the stainless steel water curtain plate. A rotating seat is inserted into the lower end of the separation mesh cylinder via a positioning block. A centrifugal motor is shaft-connected to the lower end of the rotating seat. An electrostatic precipitator is provided on the right side of the water curtain dust collector. The upper end of the electrostatic precipitator is connected to the inner cavity of the water curtain dust collector via a guide pipe.

[0006] Furthermore, a ventilation mesh is provided on the left end face of the cutting dust cover; and a viewing window is provided on the front side of the cutting dust cover, and dust conveying equipment is installed on the surface of the dust conveying pipe.

[0007] Furthermore, a sealing gasket is bonded to the lower end face of the cutting dust cover, and a drain pipe is provided on the left end face of the water curtain dust removal box; and a dust conveying pipe is connected to the upper end of the drain pipe.

[0008] Furthermore, a nozzle is installed at the upper left end of the stainless steel water curtain plate, and a water supply pipe is connected to the upper surface of the sealing cover plate; and the water supply pipe is connected to the nozzle.

[0009] Furthermore, a water-absorbing resin plate is inserted into the right side of the stainless steel water curtain plate; and the water-absorbing resin plate is correspondingly distributed at the lower opening of the guide pipe.

[0010] Furthermore, a centrifugal motor is installed on the lower surface of the water curtain dust collector, and a rotating seat is movably and sealed to the inner wall of the water curtain dust collector.

[0011] Furthermore, a fixing ring plate is welded to the upper end of the rotating seat, and the upper surface of the separating net cylinder is fastened and fixed to the fixing ring plate by fasteners.

[0012] The beneficial effects of this utility model are as follows: The LCD glass substrate cutting dust removal device of this utility model utilizes a water curtain dust removal box and an electrostatic precipitator to form a dry and wet combined dust removal mechanism. The water curtain in the water curtain dust removal box encapsulates the input glass dust, causing larger dust particles to settle. Then, the gas filtered by the water curtain is introduced into the electrostatic precipitator for further electrostatic adsorption of smaller dust particles. This facilitates the segmented processing of glass dust of different particle sizes, efficiently filters and removes dust generated during the cutting of LCD glass substrates, and improves the dust removal efficiency of the cutting dust removal device. A centrifugal motor drives the separation screen cylinder to rotate centrifugally, separating the water and glass powder particles in the mixture filtered by the water curtain. This facilitates separation, recycling, and reuse, improves resource utilization, and reduces the cost of LCD glass substrate dust treatment. Attached Figure Description

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figs. 1 to 4 As shown, this utility model provides a dust removal device for cutting liquid crystal glass substrates, including: a cutting dust cover 1, with a cutting head sleeved and connected to the upper end of the cutting dust cover 1.

[0020] A dust suction port 12 is provided on the inner wall of the right side of the cutting dust hood 1. The right end of the dust suction port 12 is connected to a water curtain dust collector 3 through a dust conveying pipe 2. A sealing cover plate 31 is attached to the upper end of the water curtain dust collector 3. A stainless steel water curtain plate 36 is fixed in the middle of the lower end face of the sealing cover plate 31. A separation net cylinder 5 is distributed at the lower end of the stainless steel water curtain plate 36. A rotating seat 52 is inserted into the lower end of the separation net cylinder 5 through a positioning block 55. A centrifugal motor 53 is shaft-connected to the lower end of the rotating seat 52. An electrostatic precipitator 4 is provided on the right side of the water curtain dust collector 3. The upper end of the electrostatic precipitator 4 is connected to the inner cavity of the water curtain dust collector 3 through a guide pipe 41.

[0021] First, the cutting dust cover 1 is installed on the surface of the cutting head, so that the lower end of the cutting dust cover 1 contacts the glass substrate to be cut through the sealing gasket 13. During the cutting process, the dust conveying equipment 21 sends the glass dust gas into the water curtain dust collector 3 through the dust conveying pipe 2. At this time, water flows down the surface of the stainless steel water curtain plate 36 in the water curtain dust collector 3 to form a water curtain, so that the dust gas flows to the water curtain. Larger dust particles are wrapped by the water curtain and fall into the separation screen cylinder 5. Smaller dust particles enter the electrostatic precipitator 4 with the air flow, so that the small dust particles in the gas are electrostatically adsorbed. Finally, the gas after adsorption treatment is discharged from the electrostatic precipitator 4, completing the dust removal and filtration.

[0022] In this embodiment, a ventilation mesh 11 is provided on the left end face of the cutting dust cover 1; and a viewing window is provided on the front side of the cutting dust cover 1, and a dust conveying device 21 is installed on the surface of the dust conveying pipe 2.

[0023] As a preferred implementation, the ventilation opening 11 facilitates the entry of external air, ensuring stable air pressure inside and outside the dustproof cover 1. The dust collection device 21 can be a Roots blower, compressor, centrifugal blower, etc., which facilitates the generation of strong suction at the dust suction port 12, drawing the generated dust into the pipeline.

[0024] In this embodiment, a sealing gasket 13 is bonded to the lower end face of the cutting dust cover 1, and a drain pipe 32 is provided on the left end face of the water curtain dust collector 3; and a dust conveying pipe 2 is connected to the upper end of the drain pipe 32. A nozzle 34 is installed on the upper left end of the stainless steel water curtain plate 36, and a water supply pipe 33 is connected to the upper end face of the sealing cover plate 31; and the water supply pipe 33 is connected to the nozzle 34. A water-absorbing resin plate 35 is inserted into the right side of the stainless steel water curtain plate 36; and the water-absorbing resin plate 35 is correspondingly distributed at the lower opening of the guide pipe 41.

[0025] As a preferred implementation, the sealing gasket 13 is made of ceramic fiber to avoid damage when in contact with the glass substrate. The drain pipe 32 facilitates the discharge of liquid separated by centrifugation from the separating screen cylinder 5. The nozzle 34 sprays water onto the stainless steel water curtain plate 36, causing the water to flow down the plate to form a water curtain. As the gas passes through the water curtain, the water curtain encapsulates large-diameter dust particles, which fall into the separating screen cylinder 5. After a single cut, the separating screen cylinder 5 rotates to separate the water and dust particles. The water-absorbing resin plate 35 absorbs moisture in the gas before it enters the electrostatic precipitator 4, reducing the impact of moisture on the electrostatic precipitator 4's adsorption. The water-absorbing resin plate 35 needs to be replaced periodically.

[0026] In this embodiment, a centrifugal motor 53 is installed on the lower surface of the water curtain dust collector 3, and a rotating seat 52 is movably and sealed to the inner wall of the water curtain dust collector 3. A fixed ring plate 51 is welded to the upper end of the rotating seat 52, and the upper surface of the separating screen cylinder 5 is fastened and fixed to the fixed ring plate 51 by fasteners 54.

[0027] In a preferred embodiment, the centrifugal motor 53 drives the rotating seat 52 to rotate, so that the separation mesh cylinder 5 fixed on the rotating seat 52 separates the water and glass powder particles in the mixture, which facilitates the separation, recycling and reuse of glass substrate dust waste, improves resource utilization, and reduces the cost of treating liquid crystal glass substrate dust.

[0028] This utility model's LCD glass substrate cutting dust removal device effectively solves the problem of low dust removal efficiency caused by the large amount of dust accumulation and frequent shutdowns for cleaning when using electrostatic adsorption to remove glass dust in existing technologies. It facilitates segmented processing of glass dust of different particle sizes, efficiently filters and removes dust generated during LCD glass substrate cutting, and improves the dust removal efficiency of the cutting dust removal device. It also facilitates separation, recycling, and reuse, improving resource utilization and reducing the cost of LCD glass substrate dust treatment. It is suitable for LCD glass substrate cutting dust removal devices.

[0029] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
