It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0032] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0033] Such as Figures 1 to 5As shown in the figure, the glass breaking device disclosed in the embodiment of the present application includes: a support assembly 10, a pressing wheel assembly 20, and a force applying assembly 30. The support assembly 10 includes at least two support structures 11. The two support structures 11 jointly support the glass to be broken and are located on both sides of the breaking line. The pressing wheel assembly 20 includes a mounting frame structure 21, a lever structure 22, and a pressing wheel structure 23. The rotating shaft of the lever structure 22 is rotatably connected to the mounting frame structure 21. The first end of the lever structure 22 is connected to the support structure 11, and the second end of the lever structure 22 is connected to the pressing wheel structure 23. The glass to be broken is arranged between the support structure 11 and the pressing wheel structure 23. The force applying assembly 30 is arranged corresponding to the breaking line.

[0034] Applying the technical solution of the embodiment of the present application, the support assembly 10 supports the glass to be broken. When controlling the support structure 11 to rise, at this time, the first end of the lever structure 22 rises, and the second end of the lever structure 22 descends. The glass is clamped between the support structure 11 and the pressing wheel structure 23. The force applying assembly 30 applies a force to the breaking line, and the glass is broken along the breaking line. During this process, since the two sides of the glass are subjected to the clamping forces from the support structure 11 and the pressing wheel structure 23, there will be no problem that the glass cannot be broken along the breaking line due to insufficient breaking force. The technical solution of this embodiment effectively solves the problem in the prior art that during the breaking process of ultra-thin glass, the glass fails to be broken along the breaking line.

[0035] As Figure 1 , Figure 2 and Figure 4 shown in the figure, in the technical solution of this embodiment, the lever structure 22 includes a first connecting portion 221, a second connecting portion 222, and a lever 223. The first end of the first connecting portion 221 is connected to the support structure 11, the second end of the first connecting portion 221 is rotatably connected to the first end of the lever 223, the second end of the lever 223 is rotatably connected to the first end of the second connecting portion 222, and the second end of the second connecting portion 222 is rotatably connected to the pressing wheel structure 23. The support structure 11 moves in the vertical direction, driving the height of the first connecting portion 221 in the vertical direction to change. The height of the first end of the lever 223 in the vertical direction changes. The lever 223 rotates along its own rotation axis. The height of the second end of the lever 223 in the vertical direction changes, and the second connecting portion 222 moves, driving the pressing wheel structure 23 to move. Since the lever 223 makes a rotational motion, the moving directions of the two ends of the lever 223 are different. Therefore, when the height of the support assembly 10 rises, the height of the pressing wheel structure 23 descends, and the two jointly fix the glass to be broken. The arrangement of the first connecting portion 221 and the second connecting portion 222 increases the height difference between the lever 223 and the glass to be broken in the vertical direction, avoiding interference between the lever 223 and the glass when the lever 223 rotates.

[0036] As Figure 1 , Figure 2 andFigure 4 As shown, in the technical solution of this embodiment, long holes are provided at the joints of the lever 223 with the first connecting portion 221 and the second connecting portion 222. Since the lever 223 rotates, the projected positions of both ends of the lever 223 in the vertical direction change. The provision of the long holes enables the joints of the first connecting portion 221 and the second connecting portion 222 with the lever 223 to rotate and translate, preventing the entire lever structure 22 from jamming. And by adjusting the connection position of the second connecting portion 222 with the lever 223, the pressing amount of the pressing wheel can be changed, avoiding excessive or insufficient pressure on the glass.

[0037] As Figure 1 , Figure 2 and Figure 4 As shown, in the technical solution of this embodiment, the mounting frame structure 21 includes a slide rail 211, and the pressing wheel structure 23 includes a first mounting seat 231 and a slider 232. The slider 232 is movably connected to the slide rail 211. The first mounting seat 231 is connected to the slider 232, and the second connecting portion 222 is rotatably connected to the first mounting seat 231. The provision of the slider 232 and the slide rail 211 guides the movement of the first mounting seat 231. The slide rail 211 is arranged in the vertical direction, thereby restricting the projected position of the first mounting seat 231 and the second end of the second connecting portion 222 in the vertical direction to remain unchanged, ensuring that the projected position of the pressing wheel structure 23 in the vertical direction remains unchanged, so that the downward pressing position of the pressing wheel structure 23 always remains the same, indicating that a change in its downward pressing position may result in an inability to apply an appropriate pressure to the glass.

[0038] As Figures 1 to 5 As shown, in the technical solution of this embodiment, the pressing wheel structure 23 further includes a second mounting seat 233, a rotating shaft 234, and a pressing wheel 235. The second mounting seat 233 is connected to the first mounting seat 231. The rotating shaft 234 is rotatably connected to the second mounting seat 233, and the pressing wheel 235 is connected to the rotating shaft 234. A bearing is provided at the joint of the rotating shaft 234 and the second mounting seat 233. The provision of the bearing reduces the friction force during the rotation of the rotating shaft, making the rotation smooth. With the interference fit between the rotating shaft and the pressing wheel 235, when the pressing wheel applies pressure to the glass, if the breaking line of the glass is offset from the position of the force applying assembly 30, the glass can be adjusted. At this time, when the glass is moved, the pressing wheel 235 rotates, driving the rotating shaft 234 to rotate together until the breaking line is aligned with the force applying assembly 30. By using the method of pressing the glass with the pressing wheel 235, when the breaking line and the force applying assembly 30 are not aligned, it is convenient to adjust the position of the glass, and the pressing wheel and the glass are in line contact, greatly reducing the contact area and avoiding damage to the glass surface.

[0039] As Figures 1 to 5As shown, in the technical solution of this embodiment, the pressing wheel 235 includes a support layer 2351, a buffer layer 2352, and a protective layer 2353. The support layer 2351, the buffer layer 2352, and the protective layer 2353 are arranged in sequence from the inside to the outside. The support layer 2351 is used to support the outer buffer layer 2352 and protective layer 2353, preventing the buffer layer 2352 and the protective layer 2353 from deforming. The buffer layer 2352 absorbs the impact generated when the pressing wheel 235 contacts the glass, preventing the glass from suddenly being stressed and causing its own rupture. The protective layer 2353 is used to protect the glass from being scratched.

[0040] As Figures 1 to 5 shown, in the technical solution of this embodiment, the support layer 2351 is made of alloy steel material, the buffer layer 2352 is made of rubber material, and the protective layer 2353 is made of sponge material. The alloy steel has high strength and is not easily deformed, which can support the outer buffer layer 2352 and protective layer 2353. The rubber material has good elasticity and can absorb the impact well, preventing the glass from being impacted by the pressing wheel 235. The sponge material is soft in texture and is not easy to scratch the glass surface when contacting the glass.

[0041] As Figures 1 to 5 shown, in the technical solution of this embodiment, the support structure 11 includes a conveying roller 111, a third mounting seat 112, and a first vertical driving part. The conveying roller 111 is rotatably connected to the third mounting seat 112. The first end of the first connecting part 221 is connected to the third mounting seat 112, and the third mounting seat 112 is connected to the first vertical driving part. Support structures 11 are arranged on both sides of the breaking roller, and conveying devices are arranged at the front end and the rear end of the conveying of the conveying roller 111. The front conveying device conveys the glass to be broken to the conveying roller 111. When the breaking line is aligned with the force-applying component 30, the conveying stops, the support structure 11 is controlled to rise, the pressing wheel structure 23 descends and presses on the glass surface to press the glass tightly, the force-applying component 30 rises to break the glass. After the support structure 11 descends and resets, the conveying roller 111 and the front and rear conveying devices continue to convey the broken glass and convey other glass to be broken to the force-applying component 30. The setting of the conveying roller 111 realizes automatic feeding and discharging, reducing labor costs.

[0042] As Figures 1 to 5 shown, in the technical solution of this embodiment, the projection of the axis of the pressing wheel 235 in the vertical direction coincides with the projection of the axis of the conveying roller 111 in the vertical direction. This makes the forces received by the glass from the conveying roller 111 and the corresponding pressing wheel 235 lie on the same straight line, preventing the glass from being affected by torque. Since the glass is thin, the glass is prone to break under the action of torque, resulting in scrapping.

[0043] As Figures 1 to 5As shown, in the technical solution of this embodiment, the force application component 30 includes a force application structure 31 and a second vertical driving part. The force application structure 31 is connected to the second vertical driving part. The force application structure 31 has a broken state close to the breaking line and a to-be-broken state away from the breaking line. The second vertical driving part drives the force application structure 31 to move in the vertical direction to break the glass. The second vertical driving part can adopt structures such as a lifting cylinder and an electric push rod. There are at least two vertical driving structures, which are respectively arranged at both ends of the force application structure 31 to ensure that the acting force applied by the force application structure 31 to the glass breaking line is uniform and ensure the flatness of the breaking line.

[0044] As described above, the technology consists of a main frame beam (mounting frame structure 21), two sets of connecting plate lever mechanisms (lever structure 22), and two sets of press wheel lifting mechanisms (press wheel structure 23). The connecting plate lever mechanism includes: a vertical top plate (first connecting part 221), a pin shaft, a lever connecting plate, a support pin shaft, a middle suspension plate (second connecting part 222), a lock nut, a "T"-shaped pin shaft, and a traction connecting plate (lever 223). The press wheel lifting mechanism includes: a slider 232, a linear slide rail (slide rail 211), an "H"-shaped slide plate, a connecting plate ear seat, a pin shaft, a press wheel shaft (rotating shaft 234), a press wheel seat (second mounting seat 233), a guide rail seat (first mounting seat 231), and a press wheel 235. The main frame beam spans the rollers in the horizontal breaking area of the production line and is installed on the roller beams on both sides, used for installing the middle suspension plate of the connecting plate lever mechanism and the guide rail seat of the press wheel lifting mechanism. A set of synchronous auxiliary pressing and breaking devices is installed above the ineffective areas on both sides of the whole plate glass at both ends of the breaking roller. The bottom parts of the vertical top plates in the two connecting plate lever mechanisms on both sides are respectively fixed on the bearing seats at both ends of the breaking roller, and move up and down in unison with the breaking roller. The other ends of the connecting plate lever mechanisms are connected to the connecting plate ear seats in the press wheel lifting mechanisms on both sides through the traction connecting plates. When the breaking roller rises or falls, the vertical top plates at both ends rise or fall synchronously, pushing the lever connecting plate to rotate in the forward and reverse directions around the support pin shaft of the middle suspension plate, and driving the press wheel 235 to fall or rise under the action of the traction connecting plate. Two press wheels 235 in each set of press wheel lifting mechanisms are symmetrically designed and are respectively pressed directly above the front and rear driving rollers adjacent to the breaking roller. When the breaking roller rises to the set highest point, at the same time, the press wheel 235 falls to the lowest point, realizing synchronous auxiliary pressing and breaking during the horizontal breaking of the glass. After the whole plate glass is instantly broken, the breaking roller descends, and the press wheel 235 rises synchronously to reset and then performs the next auxiliary pressing and breaking action. Since the lifting height of the breaking roller is only 12 mm and the breaking cycle time of the glass is 0.3 seconds, the lifting speed of the press wheel 235 is very fast. To prevent the press wheel 235 from cracking the glass when descending at high speed, the press wheel 235 is designed with three layers: a steel center layer (support layer 2351), a rubber middle layer (buffer layer 2352), and a sponge buffer protection layer (protection layer 2353). The middle suspension plate and the guide rail seat are welded under the main frame beam. One end of the connecting plate lever mechanism is respectively movably connected to the lever connecting plate through a pin shaft, and the other end of the lever connecting plate is movably connected to the traction connecting plate through a "T"-shaped pin shaft. When the breaking roller rises or falls, the vertical top plates at both ends rise or fall synchronously, and through the pin shaft, the lever connecting plate is pushed to rotate in the forward and reverse directions around the support pin shaft of the middle suspension plate. The "T"-shaped pin shaft can move left and right along the horizontal long hole to adjust the pressing amount of the press wheel 235. After adjusting to the appropriate position, the lock nut is tightened to prevent the "T"-shaped pin shaft from loosening and causing a change in the pressing amount of the press wheel 235.The linear slide rail is fixed on the guide rail seat, the slider is fixed on the "H"-shaped slide plate, the connecting plate ear seat is welded at the center position of the "H"-shaped slide plate, and is movably connected to the other end of the traction connecting plate through a pin shaft. The pressure wheel seats are symmetrically welded directly below both sides of the "H"-shaped slide plate. The pressure wheel seats are installed in the "U" groove of the pressure wheel seat through the pressure wheel shaft and rotate freely around the pressure wheel shaft. When the lever connecting plate rotates, under the action of the traction connecting plate, it drives the connecting plate ear seat, the "H"-shaped slide plate slider, and the pressure wheel 235 to descend or ascend along the two parallelly installed linear slide rails through the pin shaft.
