[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] like Figure 1 and Figure 2As shown, some embodiments of the technical solution provide a carrier glass cutting mechanism, including: a base assembly 10, a movable seat assembly 20, a cutting assembly 30, and a power drive assembly 40. The movable seat assembly 20 is movably disposed on the base assembly 10. The cutting assembly 30 includes a cutting blade connecting seat 31, a cutting blade elastic mounting seat structure 32, an air blowing structure 33, and a cutting blade 34. The cutting blade connecting seat 31 is rotatably connected to the movable seat assembly 20, the cutting blade elastic mounting seat structure 32 is mounted on the cutting blade connecting seat 31, the cutting blade 34 is mounted on the cutting blade elastic mounting seat structure 32, and the air outlet of the air blowing structure 33 is adjacent to the cutting blade. A first end of the power drive assembly 40 is rotatably connected to the movable seat assembly 20, and a second end of the power drive assembly 40 is rotatably connected to the cutting blade connecting seat 31, so as to drive the cutting assembly 30 to have a cutting state close to the object being cut, or a waiting-to-cut state away from the object being cut.

[0029] Applying the technical solution of this embodiment, during cutting, the power drive assembly 40 drives the cutting blade connecting seat 31 to move downwards, and the cutting blade 34 is in the cutting state. The cutting assembly 30 is mounted on the movable seat assembly 20, which moves on the base assembly 10, driving the cutting assembly 30 to move and realize the cutting of the carrier glass. At the same time, the air blowing structure 33 blows air onto the cutting blade 34, which can reduce the temperature of the cutting blade 34 and blow away cutting chips to avoid affecting subsequent cutting. The cutting blade 34 is set on the cutting blade elastic mounting seat structure 32, so that when the cutting blade 34 contacts the carrier glass, it has a certain buffer elastic force, which greatly reduces the damage to the carrier glass caused by rigid contact between the cutting blade and the carrier glass. The technical solution of this embodiment effectively solves the problem of easy damage to the carrier glass during cutting in the prior art.

[0030] like Figure 2 As shown, in some embodiments, the elastic mounting structure 32 for the cutting blade includes a guide seat 321, a slider 322, and a nitrogen spring 323. The guide seat 321 is connected to the cutting blade connecting seat 31. The slider 322 is movably mounted on the guide seat 321. The first end of the nitrogen spring 323 is connected to the guide seat 321, and the second end of the nitrogen spring 323 is connected to the slider 322. The cutting blade 34 is connected to the slider 322. The nitrogen spring 323 provides a buffering effect when the cutting blade 34 contacts the carrier glass. The nitrogen spring has stable elasticity, a long service life, good flexibility, good adjustability and adaptability, and is not easily affected by chips.

[0031] like Figure 1As shown, in some embodiments, the air blowing structure 33 passes through the cutting blade connecting seat 31, and the slider 322 has an air blowing port located at the front side of the cutting blade 34 in the moving direction. The air blowing structure 33 is connected to the air blowing port. The air blowing port being located at the front side of the cutting blade 34 in the moving direction allows the chips to move backward, preventing contamination of the uncut carrier glass portion. This structure is convenient to design and easy to operate.

[0032] like Figure 1 As shown, in some embodiments, the cutting blade connecting seat 31 has a first through hole, the guide seat 321 has a second through hole, and the cutting assembly 30 has a hollow screw 35 and a nut 36. The hollow screw 35 passes through the first and second through holes and is connected to the cutting blade connecting seat 31 and the guide seat 321 via the nut 36. The air blowing structure 33 includes an air blowing pipe that passes through the hollow screw 35 and is connected to the air blowing port. The above structure is compact, and the air blowing pipe is not easily interfered with by other moving parts. The air blowing pipe and the slider 322 can be connected by threads.

[0033] like Figure 1 As shown, in some embodiments, the outlet of the air blower is inclined towards the cutting blade 34, the lower air outlet surface of the air blower is tangent to the cutting edge of the cutting blade 34, and the upper air outlet surface of the air blower is higher than the cutting edge of the cutting blade 34. Under limited space conditions, this arrangement of the air blower can effectively blow away cutting chips. This embodiment considers that the cutting blade 34 will move downwards during cutting, and the aforementioned air blower can clean the area of ​​the carrier glass corresponding to the cutting blade. This embodiment uses a cutting blade 34 from the prior art; its specific structure will not be described in detail here. The cutting blade is detachably mounted on the slider 322 using fasteners. It should be noted that the upper air outlet surface of the air blower is 2mm to 6mm higher than the cutting edge of the cutting blade 34; in this embodiment, it is 3mm. The angle of inclination of the air blower outlet is 50° with the vertical direction. This inclination angle prevents cutting chips from splashing vertically onto the carrier glass to uncontrollable positions.

[0034] like Figure 1As shown, in some embodiments, the carrier glass cutting mechanism further includes an air suction assembly 50, which is disposed on the movable seat assembly 20. The air suction port of the air suction assembly 50 is located on the rear side of the cutting blade 34 in the direction of movement. The air suction assembly 50 provides a negative pressure environment to the space it is in, so that the cutting chips enter the air suction assembly 50 under the combined action of blowing and suction, avoiding contamination by the cutting chips. It should be noted that the interior of the air suction assembly 50 has a filter screen and a cutting chip receiving groove. The air suction port is also inclined, with an angle of 60° between the air suction port and the vertical direction, and the width of the air suction port is greater than the width of the blowing port, being twice the width of the blowing port. The bottom of the air suction port extends towards the cutting blade 34, 2mm below the lowest part of the cutting blade 34, and the upper side of the air suction port extends towards the cutting blade 34, 2mm to 10mm above the lowest part of the cutting blade 34. The bottom of the chip-collecting groove is removable for easy chip removal, and the upper part of the chip-collecting groove has a filter screen that is higher than the air intake.

[0035] like Figure 2 As shown, in some embodiments, the guide seat 321 includes a seat body and a connecting plate extending laterally at the upper end of the seat body. A second through hole is located on the laterally extending connecting plate. The slider 322 has a laterally extending limiting plate with a third through hole through which a hollow screw 35 passes. The limiting plate can move axially along the hollow screw 35, i.e., move up and down. The aforementioned connecting plate and limiting plate facilitate the setting of the second and third through holes, are less likely to damage the structure of the guide seat 321 and the slider 322, and allow for more flexible setting of the hollow screw. The third through hole of the limiting plate on the slider 322 is a smooth hole, which facilitates its mating with the hollow screw.

[0036] like Figure 1 As shown, in some embodiments, the power drive assembly 40 includes a cylinder, the first end of which is rotatably connected to the movable seat assembly 20, and the second end of which is rotatably connected to the cutting blade connecting seat 31. This structure is convenient to operate. The movable seat assembly 20 and the cutting blade connecting seat 31 are approximately 90° apart. For example, in the waiting-to-cut state, the angle between the movable seat assembly 20 and the cutting blade connecting seat 31 is 80°, and in the cutting state, the angle is 90°. It should be noted that the carrier glass cutting mechanism of this embodiment also includes a control assembly. A pressure detector is provided on the nitrogen spring 323. The control assembly is electrically connected to both the power drive assembly 40 and the pressure detector, and controls the force between the cutting blade and the carrier glass through the control assembly.

[0037] In some embodiments, the movable seat assembly 20 includes a movable motor, a screw, and a movable seat. The movable motor is mounted on the base assembly 10, the screw is connected to the output shaft of the movable motor, and the movable seat has a threaded hole adapted to the screw. The movable seat and the base assembly 10 have a mutually cooperating slide rail structure. The cooperative structure of the motor, screw, and movable seat enables the movable seat to achieve high movement accuracy. It should be noted that the base assembly 10 has a T-shaped slide rail, and the movable seat has a T-shaped slide groove. The slide rail and slide groove move relative to each other, and the structure of the T-shaped slide rail and T-shaped slide groove allows the movable seat to withstand a certain amount of force.

[0038] This application also provides a cutting device, which includes a conveying mechanism and a carrier glass cutting mechanism that cooperates with the conveying mechanism. The carrier glass cutting mechanism is the aforementioned carrier glass cutting mechanism.

[0039] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this application.
