Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass cutting, in particular to a laser cutting device and method for laminated glass. BACKGROUND

[0002] Laminated glass (i.e. laminated glass) is made of two or more layers of flat glass (or heat-bent glass) sandwiched with PVB film, and is a high-grade safety glass made by high pressure. It has been widely used in various fields, mainly including solar glass, decorative glass, engineering glass, bathroom glass, automobile glass, etc. Laminated glass has good sound insulation and heat preservation performance, and can reduce solar radiation and improve strength. In addition, the glass fragments will not scatter everywhere after breaking, but will be glued together, which is safe. During the production and processing of laminated glass, laser cutting equipment is needed for cutting operation.

[0003] However, the existing laser cutting equipment for laminated glass usually places the laminated glass on the cutting table for cutting operation. However, during the cutting process, the laminated glass may move, which is not stable and reliable, thereby affecting the cutting quality. In addition, the surface of the cutting table may be attached with impurities, which will make the laminated glass uneven after being placed, and also affect the cutting quality. SUMMARY

[0004] The present application provides a laser cutting device and method for laminated glass to solve the problem that the existing laser cutting equipment for laminated glass is usually placed on the cutting table for cutting operation, but during the cutting process, the laminated glass may move, which is not stable and reliable, thereby affecting the cutting quality, and the surface of the cutting table may be attached with impurities, which will make the laminated glass uneven after being placed, and also affect the cutting quality.

[0005] The technical scheme for solving the above technical problems is as follows: a laser cutting device for laminated glass, comprising a cutting table and a cutting head arranged on the body of the laser cutting device, the top of the cutting table is connected with two symmetrically arranged clamping plates through a reset mechanism, and the top of the clamping plate is fixedly connected with two symmetrically arranged fixed plates, the side wall of the fixed plate is provided with an inclined surface, and the side wall of the clamping plate is provided with a cleaning mechanism for cleaning the side edge of the laminated glass and the cutting table, and the top of the cutting table is provided with an adsorption mechanism for adsorbing the bottom of the laminated glass.

[0006] The beneficial effects of the present application are:

[0007] 1) By setting a reset mechanism, when laser cutting of laminated glass is required, the laminated glass is pressed down along the inclined plane, causing it to slide along the inclined plane. At the same time, the two clamping plates are pushed away from each other. When the clamping plates move, the first piston is pushed by the first push rod. When the first piston moves, it squeezes the hydraulic oil in the L-shaped tube and pushes the counterweight upward. When the laminated glass slides between the two clamping plates and makes horizontal contact with the top of the cutting table, the two clamping plates clamp and limit the laminated glass under the action of the counterweight. This makes it easy to clamp and limit laminated glass of different sizes, prevents it from moving, and ensures that the clamping force of the clamping plates on the laminated glass is constant. This ensures the clamping effect while avoiding damage to the laminated glass. It also makes the glass more stable and reliable when the cutting head performs laser cutting, ensuring the quality of the cutting.

[0008] 2) By setting up an adsorption mechanism, when clamping and limiting the laminated glass, the bottom of the laminated glass first abuts against the suction cup. As the laminated glass continues to move downward, it pushes the moving tube and moving plate downward. At the same time, the third spring is compressed. Furthermore, when the two clamping plates move away from each other, the third push rod drives the two third pistons to move away from each other, thereby performing an air extraction operation on the suction cup. This allows the air inside the suction cup to enter the second fixed tube through the moving tube and telescopic tube, generating negative pressure inside the suction cup. When the laminated glass is in horizontal contact with the top of the cutting table, the suction cup is stored in the storage groove, thus adsorbing the bottom of the laminated glass and preventing it from moving. This makes it more stable and reliable when the cutting head performs laser cutting, ensuring the quality of the cutting.

[0009] 3) By setting up a cleaning mechanism, when the laminated glass is clamped and limited, as the two clamping plates move away from each other, the second piston is pushed by the second push rod to slide inside the first fixed tube, thereby compressing the air inside the first fixed tube and gradually increasing the air pressure inside the first fixed tube. At this time, the first one-way component closes. When the pressure is greater than the elastic force of the second sealing ball, the second conical tube is pushed to move away from the second spring, so that the second sealing ball no longer abuts against the inner wall of the second conical tube. At this time, the air inside the first fixed tube is compressed and enters the cavity through the air outlet and hose, and is blown out through the air blowing hole. Thus, when the laminated glass slides down along the side wall of the clamping plate, the clamping surface of the laminated glass and the surface of the cutting table can be automatically cleaned by blowing air, ensuring the clamping effect of the laminated glass. At the same time, it prevents it from tilting after clamping, thereby ensuring the quality of its cutting. When the cut laminated glass is taken out, the second piston moves back to its original position. At the same time, the first one-way component opens and the second one-way component closes. At this time, external air enters the first fixed tube through the air inlet pipe.

[0016] The beneficial effect of the above further scheme is that when the two clamping plates move away from each other during clamping and limiting the laminated glass, the second piston is pushed to slide in the first fixed pipe by the second push rod, thereby extruding the air in the first fixed pipe, so that the air pressure in the first fixed pipe gradually increases, at this time, the first one-way assembly is closed, when the pressure is greater than the elastic force of the second sealing ball, the second conical pipe moves away from the second spring, so that the second sealing ball no longer abuts against the inner side wall of the second conical pipe, at this time, the air in the first fixed pipe is extruded and enters the cavity through the air outlet pipe and the hose, and is blown out through the air blowing hole, thereby when the laminated glass slides down along the side wall of the clamping plate, the clamping surface of the laminated glass and the surface of the cutting table can be automatically blown and cleaned, the clamping effect of the laminated glass is ensured, and at the same time, tilting of the laminated glass after clamping is avoided, thereby ensuring the cutting quality, when the cut laminated glass is taken out, the second piston moves back to the original position, at the same time, the first one-way assembly is opened, and the second one-way assembly is closed, at this time, the external air enters the first fixed pipe through the air inlet pipe.
