[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figures 1 to 4 As shown, the glass cutting and breaking device disclosed in the first embodiment of the present application includes: a frame assembly 10, a conveying assembly 20, a limiting assembly 30, a force assembly 40 and a cutting assembly 50, the conveying assembly 20 is connected to the frame assembly 10, the glass to be processed is arranged on the conveying assembly 20, the limiting assembly 30 is located on the side of the glass to be processed away from the conveying assembly 20, the force assembly 40 includes a force structure 41, a connecting structure 42, a guide structure 43 and a horizontal driving structure 44, the output end of the horizontal driving structure 44 is connected to the guide structure 43, the guide structure 43 includes an inclined section 431, the connecting structure 42 abuts on the inclined section 431, the force structure 41 is connected to the connecting structure 42 and is located on the side of the connecting structure 42 away from the guide structure 43, the force structure 41 is arranged corresponding to the conveying assembly 20, and the cutting assembly 50 is located on the side of the force assembly 40 close to the feeding end of the conveying assembly 20.

[0034] By applying the technical solution of the first embodiment, after placing the glass at a suitable position on the conveying assembly 20, the conveying assembly 20 starts to convey the glass to be cut to the cutting assembly 50, and the cutting assembly 50 cuts the glass. The distance between the cutting assembly 50 and the force-applying assembly 40 along the conveying direction of the conveying assembly 20 remains unchanged. The conveying time is controlled according to the running speed of the conveying assembly 20, and the glass can be accurately conveyed from the scribed position to the force-applying structure 41. The horizontal driving structure 44 drives the guide structure 43 to move horizontally, and the inclined section 431 moves along the horizontal direction, so the position of the connecting structure 42 against the inclined section 431 changes, and the connecting structure 42 moves in the vertical direction to drive the force-applying structure 41 to move in the vertical direction. The force-applying structure 41 provides an upward external force for the glass, and the limit assembly 30 limits the upward movement of the glass. The glass is cracked along the breaking seam under the action of the external force, and the breaking is completed. The technical solution of the first embodiment effectively solves the problem of low breaking efficiency due to secondary positioning in the process of breaking the glass in the prior art.

[0035] like Figures 1 to 3As shown, in the technical solution of the first embodiment, the limiting assembly 30 includes a first limiting structure 31 and a second limiting structure 32, and there is a predetermined spacing between the first limiting structure 31 and the second limiting structure 32, and the projection of the force structure 41 in the vertical direction is located between the projection of the first limiting structure 31 in the vertical direction and the projection of the second limiting structure 32 in the vertical direction. The conveying assembly 20 conveys the cut glass so that the glass scribe line is aligned with the force structure 41, and the force structure 41 moves upward, and the glass moves upward under the action of external force, and the first limiting structure 31 and the second limiting structure 32 are respectively located on both sides of the scribe line, and the scribe line is subjected to the upward force from the force structure 41, and the two sides of the scribe line are subjected to the downward force from the first limiting structure 31 and the second limiting structure 32, respectively, and the glass is broken along the scribe line. The first limiting structure 31 and the second limiting structure 32 limit the upward displacement of the glass while providing downward force on both sides of the score line, and work together with the force-applying structure 41 to break the glass. The downward pressure on both sides of the score line of the glass can effectively avoid the problem of edge cracking during the breaking process.

[0036] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the first limiting structure 31 and the second limiting structure 32 each include a plurality of first limiting structures 31 and a plurality of second limiting structures 32, and the plurality of first limiting structures 31 and the plurality of second limiting structures 32 are arranged one by one. The plurality of first limiting structures 31 and the plurality of second limiting structures 32 apply uniform force to both sides of the glass scribe line, further preventing cracks from occurring at the edge of the glass during the breaking process.

[0037] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the inclined section 431 includes a first groove 4311, and the connecting structure 42 is movably arranged in the first groove 4311. The side wall of the first groove 4311 limits the connecting structure 42, preventing the connecting structure 42 from moving along the conveying direction parallel to the conveying assembly 20, causing the connecting structure 42 to separate from the guide structure 43, causing the entire structure to fail, and the force-applying structure 41 cannot move upward to break off.

[0038] like Figures 1 to 4As shown, in the technical solution of the first embodiment, the connection structure 42 includes a connection part 421 and a rotating part 422, the rotating part 422 is connected to the connection part 421, the force-applying structure 41 is connected to the connection part 421 and is located on the side of the connection part 421 away from the rotating part 422, and the rotating part 422 is arranged in the first groove 4311. The rotating part 422 is a roller, and the roller is rollably arranged in the first groove 4311. When the guide structure 43 moves, the rotating part 422 rolls in the inclined section 431, and the height of the rotating part 422 in the vertical direction changes, thereby changing the height of the connection part 421 and the force-applying structure 41 in the vertical direction. The setting of the rotating part 422 converts the sliding friction between the connection structure 42 and the guide structure 43 into rolling friction, reduces the friction force, reduces the wear between the two, and increases the service life, while reducing the output power of the horizontal drive structure 44, saving energy.

[0039] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the connecting portion 421 includes a second groove and a third limiting portion 4211, the first end of the third limiting portion 4211 is connected to the frame assembly 10, and the second end of the third limiting portion 4211 is movably arranged in the second groove. The width of the second groove increases continuously along the direction from approaching to away from the third limiting portion 4211, and the size of the second end of the third limiting portion 4211 decreases continuously along the direction from approaching to away from the second groove. This structure ensures that the third limiting portion 4211 will not be separated from the second groove. The third limiting portion 4211 is fixed on the frame assembly 10, and the second groove is arranged in the vertical direction. When the connecting structure 42 moves in the vertical direction, the position of the second groove in the vertical direction changes. The arrangement of the above structure avoids the problem that when the guide structure 43 moves in the horizontal direction, the connecting structure 42 moves in the horizontal direction, resulting in the inability of the force-applying structure 41 to move in the vertical direction and the inability to break the glass.

[0040] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the conveying assembly 20 includes a first conveying structure 21 and a second conveying structure 22, the first conveying structure 21 is arranged correspondingly to the first limiting structure 31, and the second conveying structure 22 is arranged correspondingly to the second limiting structure 32. When the conveying assembly 20 conveys the glass to the force-applying structure 41, the first conveying structure 21 and the second conveying structure 22 are respectively located on both sides of the scribe line to avoid interference between the force-applying structure 41 and the conveying assembly 20 when the force-applying structure 41 moves.

[0041] like Figures 1 to 4As shown, in the technical solution of the first embodiment, the cutting assembly 50 includes a driving structure 51 and a cutting structure 52, the driving structure 51 is connected to the cutting structure 52, and the cutting structure 52 is arranged toward the conveying assembly 20. The cutting structure 52 moves under the action of the driving structure 51 to scribe the glass. The arrangement of the cutting assembly 50 enables the scribe and break of the glass to be arranged at the same station, thereby improving the work efficiency.

[0042] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the driving structure 51 includes a horizontal driving part 511 and a vertical driving part 512, the vertical driving part 512 is connected to the cutting structure 52, and the horizontal driving part 511 is connected to the vertical driving part 512. The horizontal driving part 511 is arranged vertically to the conveying direction of the conveying assembly 20, so that the glass marking is perpendicular to the conveying direction of the conveying assembly 20 and parallel to the arrangement direction of the force structure 41. The vertical driving part 512 uses a lifting cylinder to control the cutting structure 52 to approach or move away from the glass to be marked, and the height of the cutting structure 52 in the vertical direction can be adjusted according to the thickness of the glass. The glass cutting and breaking device also includes a control component, which is connected to the cutting component 50, the control component is connected to the force component 40, and the control component is connected to the conveying component 20. The control component sends a signal to the cutting component 50 to mark the glass. After the marking is completed, the conveying component 20 is started. Since the distance between the cutting structure 52 and the force-applying structure 41 along the conveying direction of the conveying component 20 remains unchanged, when the conveying speed of the conveying component 20 remains unchanged, the time it takes for the glass to move to the force-applying structure 41 after the marking is completed remains unchanged. The running time of the conveying component 20 is controlled according to the time, so that the marking position is just above the force-applying structure 41, and the conveying component 20 stops running. The control component sends a signal to the horizontal driving structure 44, so that the force-applying structure 41 moves upward to break the glass.

[0043] like Figure 5As shown, the difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the first limiting structure 31 includes a first mounting seat 311 and a first limiting portion 312, the first mounting seat 311 is fixed on the frame assembly 10, the first limiting portion 312 is rotatably connected to the first mounting seat 311, and the second limiting structure 32 includes a second mounting seat 321 and a second limiting portion 322, the second mounting seat 321 is fixed on the frame assembly 10, and the second limiting portion 322 is rotatably connected to the second mounting seat 321. Since both the first limiting portion 312 and the second limiting portion 322 can rotate, as the two rotate, the distance between the end away from the first mounting seat 311 or the second mounting seat 321 and the conveying assembly 20 changes, so the limiting assembly 30 of the second embodiment can be applied to the limiting of glass plates of different thicknesses, and has stronger versatility. The first limiting part 312 includes a first roller, and the second limiting part 322 includes a second roller. When the glass is installed, the first roller and the second roller are adjusted to a suitable position so that the lower surface of the glass contacts the conveying assembly 20, and the upper surface of the glass contacts the first roller and the second roller. Both the first roller and the second roller can rotate, and they rotate as the glass is conveyed. The arrangement of the first roller and the second roller further ensures that the glass is not easy to slide when placed on the conveying assembly 20, and because the first roller and the second roller are in direct contact with the glass, the glass will not move upward, and the limiting effect is better.

[0044] In summary, the purpose of the present application is to provide a cutting and breaking device (glass cutting and breaking device) to reduce the safety risk of workers and improve production efficiency. To achieve the above purpose, a cutting and breaking device (glass cutting and breaking device) is provided, which is specifically composed of: a cutting system (cutting component 50), a driving system (conveying component 20), a pressure wheel system (limiting component 30), a lifting and breaking roller (force applying component 40) and a bracket (frame component 10). The cutting system is composed of a cutting knife (cutting structure 52), a roller, a cylinder (vertical drive unit 512), etc. The cutting knife and the roller are installed on a roller seat and can be driven up and down by the cylinder; the driving system includes a motor, a transmission device, a guide rail (horizontal drive unit 511), etc., which are used to complete the linear reciprocating motion of the cutting system; the pressure wheel system is composed of a bracket, a pressure wheel (a first limiting structure 31 and a second limiting structure 32), and several groups of pressure wheels are arranged side by side, and the pressure wheel height is set at a suitable position above the belt conveyor; the lifting and breaking roller (force-applying component 40) is composed of a cylinder (horizontal drive structure 44), a breaking roller (force-applying structure 41), a track plate (guide structure 43), and a lifting wheel (rotating part 422); the cylinder push rod is fixed on the track plate, pushes the guide plate to move back and forth, and drives the lifting wheel on the guide The upper track plate moves up and down along the guide rail, and the breaking roller is fixed on the lifting wheel and moves up and down with the lifting wheel; the cutting system, driving system, pressure wheel system and lifting breaking roller are fixed on the bracket as shown in the figure. When the glass passes through, the driving system drives the cutting system to the glass position, and the cylinder drives the cutting knife to press down on the glass surface, cutting a knife mark along the guide rail direction. After the cutting action is completed, the cylinder drives the cutting knife to lift up, and the glass continues to move forward. When the knife mark part of the glass runs above the lifting breaking roller, the cylinder moves, the breaking roller is lifted, and the glass moves upward. When the glass is lifted upward, the glass on both sides of the breaking roller will hit the pressure wheel of the pressure wheel system. Under the action of force, the glass will be broken along the knife mark position to complete the cutting and breaking action. The whole system reduces the safety risk of workers for automated equipment and improves production efficiency.
