Description

Technical Field

[0001] The utility model relates to the field of automatic processing of glass substrates, and more particularly to a glass cutting dust removal device. Background Art

[0002] The cleanliness of the surface of optical glass is a very important indicator. Therefore, in each process of glass production, control should be carried out from various aspects such as the production environment, production equipment, and production process to reduce or avoid contamination of the glass. At present, scribing is the main link to ensure the size of the glass, and it is basically inevitable to generate dust during the scribing process. Therefore, various dust removal methods are adopted to reduce dust pollution, which is essential. However, currently, the general method is to directly suck the dust. For example, a dust-proof device for glass curtain wall cutting with the publication number CN212331462U uses a method of blowing from one side and sucking from the other side to remove dust, which indeed reduces the related defects of floating dust, but there is still no way to solve the problem of slightly adhered dust, and the dust removal effect is poor. In addition, during long-term production, the wear and dust generation of the scribing tool head installation component become a pollution factor, resulting in a decline in product quality.

[0018] The present utility model will be further described below with reference to the drawings.

[0019] As Figure 1 – Figure 3As shown in the figure, Embodiment 1: A glass cutting dust removal device includes a scribing main body 1. An air dust removal cover 3 is provided outside the scribing main body 1. The top of the air dust removal cover 3 is hermetically connected to the scribing main body 1. A blowing cavity 6 is provided between the inner and outer walls of the cover body of the air dust removal cover 3. A compressed air inlet 5 is opened on the outer wall of the cover body of the air dust removal cover 3. The compressed air inlet 5 is communicated with the blowing cavity 6. The bottom of the cover body of the air dust removal cover 3 is provided with a compressed air outlet 9 of the continuous blowing cavity 6. A dust removal cavity 7 is formed between the inner wall of the cover body of the air dust removal cover 3 and the scribing main body 1. The dust removal cavity 7 is communicated with a dust discharge port 4 on the air dust removal cover 3. A dust suction port 10 is formed between the dust removal cavity 7 and the scribing main body 1. The compressed air outlet 9 is located outside the dust suction port 10, so that the air blown out from the compressed air outlet 9 forms a closed air wall space to prevent dust from overflowing. The dust suction port 10 sucks away the dust inside.

[0020] Embodiment 2: A glass cutting dust removal device. Dust discharge ports 4 and compressed air inlets 5 are provided on all four surfaces of the air dust removal cover 3. The blowing cavities 6 on the four sides are communicated with each other to form an air wall around. The dust removal cavities 7 on the four sides are communicated with each other to increase the blowing force and the dust suction force. The bottom of the inner and outer walls of the cover body of the air dust removal cover 3 is an inclined side wall 8, so that the air blown out from the compressed air outlet 9 has a certain inclination angle, which is convenient for rolling up the dust generated during the cutting of the cutting tool 11, so that the dust suction port 10 can suck away the dust. The top of the air dust removal cover 3 and the scribing main body 1 are sealed by a sealing ring 2. A separating ring is provided between the air dust removal cover 3 and the scribing main body 1. The separating ring separates the air dust removal cover 3 from the scribing main body 1. After the bolt passes through the gasket, the air dust removal cover 3 and the separating ring, the air dust removal cover 3 is fastened to the scribing main body 1. Others are the same as those in Embodiment 1.

[0021] Connect the compressed air to the compressed air inlet 5, and connect the dust suction device to the dust discharge port 4. When the scribing main body 1 cuts the glass, the compressed air enters the blowing cavity 6 between the inner and outer walls of the air dust removal cover 3 through the compressed air inlet 5 and blows towards the glass surface. The blowing angle is inward. On the one hand, the high-intensity blowing rolls up the dust adsorbed on the glass surface. On the other hand, the blowing on the four sides forms a closed space to prevent dust from overflowing. At this time, the dust suction port 10 sucks air outwards to form a vacuum environment between the scribing main body 1 and the air dust removal cover 3. The blowing on the four sides rolls up the dust inwards and discharges it through the dust removal cavity 7 and the dust discharge port 4. Since the vacuum space surrounds the scribing main body 1, the dust generated by the wear of the cutting tool 11 is also purified together.

[0022] The bottom of the cover body of the air dust removal cover 3 is not limited to a square, and can also be a circle, etc., as long as a continuous relatively airtight outer air wall can be formed outside the dust suction port 10.
