[0031] All terms used in this application have the same meaning as those understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[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] See also Figure 1 and Figure 2 The embodiment of the present application provides a cutting device, including a cutting assembly, wherein the cutting assembly includes a cutter body 1 and two cutter wheels 2. The cutter wheel 2 is rotatably connected to the cutter body 1, and the two cutter wheels 2 are arranged at intervals on the cutter body 1. The diameter of one of the two cutter wheels 2 is L, and the diameter of the other is M, satisfying 0.05≤LM≤0.1mm.

[0034] The cutter body 1 is used for mounting the cutter wheel 2 .

[0035] The cutter wheel 2 is used for cutting glass.

[0036] Of the two cutter wheels 2, the cutter wheel 2 with a small diameter is used to preliminarily cut the glass to form a cutting groove, and the cutter wheel 2 with a large diameter is used to further cut the glass along the cutting groove, and the two parts of the cut glass can be separated along the cutting groove. Compared with the traditional cutting method, the purpose of cutting the glass can be achieved without breaking the glass, which improves the cutting efficiency. In addition, the safety of cutting the glass is increased without breaking the glass.

[0037] Of the two cutter wheels 2, one has a diameter of L and the other has a diameter of M, satisfying 0.05≤LM≤0.1mm. The advantage of such a setting is that if LM≤0.05mm, the large-diameter cutter wheel 2 cannot separate the glass well. If LM≥0.1mm, the diameter of the large-diameter cutter wheel 2 is too large, and it is easy to form cracks in the glass when separating the glass, reducing the cutting effect. Therefore, when LM satisfies 0.05≤LM≤0.1mm, the large-diameter cutter wheel 2 can achieve both a good cutting effect and a good separation effect.

[0038] The cutter wheel 2 can be selected from the existing cutter wheels 2, and its structure is well known to those skilled in the art and will not be described in detail here.

[0039] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the cutting device further comprises a platform 3, a slide rail 4 and a moving assembly. The platform 3 is used to place glass, the slide rail 4 is arranged on the platform 3, the moving assembly comprises a seat body 5, a travel wheel 6, a planetary gear component 7, a switching component 8 and a screw moving platform 13, the travel wheel 6 is rotatably connected to the seat body 5, the travel wheel 6 is accommodated in the slide rail 4, the planetary gear component 7 comprises a sun gear 16, a planetary gear 17, a planetary carrier 19 and an inner gear ring 18, the sun gear 16 is rotatably connected to the seat body 5, the inner gear ring 18 is rotatably connected to the seat body 5, the inner gear ring 18 is arranged around the circumference of the sun gear 16, the inner gear ring 18 is connected to the travel wheel 6, the planetary gear 17 is arranged between the sun gear 16 and the inner gear ring 18, the planetary gear 17 is rotatably connected to the planetary carrier 19, the switching component 8 is used to selectively lock the inner gear ring 18 or the planetary carrier 19, the planetary carrier 19 is connected to the screw 24 of the screw moving platform 13, and the cutting assembly is connected to the moving end of the screw moving platform 13.

[0040] The platform 3 may be provided with a fixing part 27 for fixing the glass. The fixing part 27 may be selected from existing structures and will not be described in detail here.

[0041] The seat body 5 may be connected to the slide rail 4 or may not be connected to the slide rail 4. For example, the seat body 5 may be connected to the slide rail 4 in a sliding manner.

[0042] The running wheel 6 is accommodated in the slide rail 4 so that the running wheel 6 can move along the slide rail 4 .

[0043] The sun gear 16 and the planetary gears 17 are meshed with each other, and the planetary gears 17 and the internal ring gear 18 are meshed with each other.

[0044] The screw moving platform 13 is used to move the cutting assembly, that is, the cutting assembly is connected to the moving end. When the screw 24 rotates, the moving end moves under the action of the screw 24, so that the cutting assembly can cut the glass.

[0045] The planet carrier 19 may include a plurality of arms 20 , the plurality of arms 20 are connected to each other, and each planetary gear 17 is rotatably connected to each arm 20 .

[0046] The planetary gear component 7 includes two working states, one is that the inner ring gear 18 is locked, at this time the sun gear 16 rotates, driving the planet carrier 19 to rotate. The other is that the planet carrier 19 is locked, at this time the sun gear 16 rotates, driving the inner ring gear 18 to rotate.

[0047] Under the action of the switching component 8, the working state of the planetary gear component 7 can be switched as needed. When it is necessary to adjust the position of the cutting assembly along the slide rail 4, the planetary gear component 7 can be set to a state where the inner gear ring 18 is unlocked and the planet carrier 19 is locked. At this time, the sun gear 16 is the active gear. Under the action of the sun gear 16, the inner gear ring 18 drives the running wheel 6 to rotate. When the cutting assembly is required to cut glass, the planetary gear component 7 can be set to a state where the planet carrier 19 is unlocked and the inner gear ring 18 is locked. At this time, the sun gear 16 is the active gear. Under the action of the sun gear 16, the planet carrier 19 drives the screw rod 24 to rotate.

[0048] Under the action of the planetary gear component 7, the sun gear 16 can respectively drive the travel wheel 6 to move and the lead screw 24 to rotate, which saves costs and makes the cutting equipment more integrated and more compact.

[0049] The component for driving the sun gear 16 to rotate can be selected from existing equipment. For example, the sun gear 16 can be driven by the motor 15.

[0050] In the embodiment of the present application, a friction layer may be provided between the running wheel 6 and the slide rail 4, so that when the running wheel 6 is locked, the risk of slipping between the running wheel 6 and the slide rail 4 is reduced.

[0051] In the embodiment of the present application, the cutting assembly can include two working states, one is that when the base body 5 moves along the slide rail 4, the cutting assembly can cut the glass along the extension direction of the slide rail 4, and the other is that when the moving end of the screw moving platform 13 moves, the cutting assembly cuts the glass along the axial direction of the screw 24. The switching of the working state of the cutting assembly can be achieved by setting a position adjustment device at the moving end of the screw moving platform 13. The position adjustment device can be selected from existing products and will not be described here.

[0052] The running wheel 6 can be sleeved on the outer peripheral wall of the inner gear ring 18, so that when the inner gear ring 18 rotates, it can drive the running wheel 6 to rotate together.

[0053] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the moving component also includes a driven wheel 11, which is rotatably connected to the base body 5, and the driven wheel 11 is accommodated in the slide rail 4. The driven wheel 11 is coaxially provided with a driven gear 10, and the base body 5 is rotatably provided with an intermediate gear 9. The driven gear 10 and the intermediate gear 9 are meshed. The inner ring gear 18 is provided with a meshing component 12 around the circumference of the inner ring gear 18, and the meshing component 12 is used to mesh with the intermediate gear 9.

[0054] The driven wheel 11 is accommodated in the slide rail 4 so that the driven wheel 11 can move along the slide rail 4 .

[0055] When the inner gear ring 18 rotates, the meshing part 12 rotates together with it. Under the action of the meshing part 12, the intermediate gear 9 drives the driven gear 10 to rotate, and then the driven wheel 11 rotates. The advantage of this arrangement is that, on the one hand, the running wheel 6 and the driven wheel 11 can move synchronously, which improves the accuracy of the movement of the seat body 5 along the slide rail 4. On the other hand, when the running wheel 6 is locked, the driven wheel 11 can be locked together, reducing the risk of the running wheel 6 slipping relative to the slide rail 4.

[0056] See also Figure 5 In some embodiments, the meshing member 12 includes a fixed portion 27, a telescopic portion 26 and an elastic member. The fixed portion 27 is connected to the inner gear ring 18, the telescopic portion 26 is movably connected to the fixed portion 27 along the radial direction of the inner gear ring 18, and the telescopic portion 26 is clamped between adjacent teeth of the intermediate gear 9. The elastic member is connected to the fixed portion 27 and the telescopic portion 26.

[0057] The elastic member may be a spring, and is used to provide an elastic force that enables the telescopic portion 26 to approach the intermediate gear 9 .

[0058] When the meshing member 12 and the intermediate gear 9 mesh, the telescopic portion 26 first enters between adjacent teeth of the intermediate gear 9 , and then the telescopic portion 26 is pushed to move away from the intermediate gear 9 , so that the telescopic portion 26 can pass through the intermediate gear 9 .

[0059] After the position of the telescopic part 26 relative to the fixed part 27 is locked, when the telescopic part 26 abuts against the intermediate gear 9, since the telescopic part 26 cannot move relative to the fixed part 27, the intermediate gear 9 and the inner ring 18 are locked, thereby achieving the purpose of locking the inner ring 18 and also enabling the driven wheel 11 to be locked at the same time, reducing the risk of the walking wheel 6 slipping relative to the slide rail 4.

[0060] It should be noted that when the inner gear ring 18 is locked, the inner gear ring 18 can still rotate in the reverse direction. At this time, a spring can be set between the slide rail 4 and the seat body 5 to prevent the walking wheel 6 from moving in the reverse direction, and thus the inner gear ring 18 cannot rotate in the reverse direction.

[0061] The meshing component 12 meshes with the intermediate gear 9 to drive the intermediate gear 9 to rotate. On the one hand, the meshing component 12 can play a role similar to a gear, so that the intermediate gear 9 can be driven to rotate. On the other hand, since the telescopic part 26 can move radially along the inner ring gear 18, it is convenient to adjust the transmission ratio between the intermediate gear 9 and the inner ring gear 18.

[0062] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the switching component 8 includes a moving portion 21 and a supporting portion 22. The moving portion 21 is movably connected to the planet carrier 19 along the axial direction of the sun gear 16, and the seat body 5 is provided with a limiting hole 23, and the moving portion 21 is inserted into the limiting hole 23 to lock the planet carrier 19. The supporting portion 22 is provided on the moving portion 21, and is used to abut against the side of the telescopic portion 26 away from the intermediate gear 9 to lock the inner gear ring 18.

[0063] Along the moving direction of the moving part 21, the limiting hole 23 and the abutting part 22 can be respectively arranged on both sides of the moving part 21. When the moving part 21 is inserted into the limiting hole 23, the planet carrier 19 is locked, and the abutting part 22 is separated from the telescopic part 26, so that the abutting part 22 cannot limit the telescopic part 26, and the inner gear ring 18 can rotate normally. On the contrary, when the abutting part 22 abuts against the telescopic part 26, the moving part 21 is separated from the limiting hole 23, and the planet carrier 19 can rotate, and the inner gear ring 18 is locked.

[0064] See also Figure 6 In some embodiments, the abutting portion 22 is in the shape of a hollow cone, and the telescopic portion 26 abuts against the outer peripheral wall of the abutting portion 22 .

[0065] The abutting portion 22 is in a hollow cone shape, so that the abutting portion 22 can push the telescopic portion 26 to move. At the same time, since the abutting portion 22 is a hollow structure, the abutting portion 22 as a whole can form a ring structure. When the planet carrier 19 rotates, the abutting portion 22 can remain abutted against the telescopic portion 26 facing the intermediate gear 9, so that the inner gear ring 18 can be locked.

[0066] The telescopic portion 26 may be provided with rollers to reduce the friction between the telescopic portion 26 and the abutting portion 22 .

[0067] In some embodiments, the screw moving platform 13 includes a screw 24, a guide rod 25 and a mounting portion. The screw 24 is connected to the planet carrier 19, the guide rod 25 is connected to the seat body 5, the screw 24 is threadedly connected to the mounting portion, the mounting portion is movably connected to the guide rod 25, and the cutter body 1 is connected to the mounting portion.

[0068] In the embodiment of the present application, the slide rails 4 can be set in parallel to be two, and the two slide rails 4 can be respectively provided with a seat body 5. The two ends of the guide rod 25 can be respectively connected to the two seat bodies 5. One end of the screw rod 24 can be connected to the planetary carrier 19, and the other end is connected to another seat body 5.

[0069] The mounting portion may be provided with a guide hole, and the guide rod 25 is passed through the guide hole.

[0070] Since the screw rod 24 is threadedly connected to the mounting portion, when the screw rod 24 rotates, the mounting portion can move along the axial direction of the screw rod 24, thereby achieving the purpose of moving the cutting assembly along the axial direction of the screw rod 24.

[0071] In the embodiment where the screw moving platform 13 includes a moving end, the mounting portion is the moving end.

[0072] The mounting portion may be provided with a lifting component, such as a cylinder, and the blade body 1 may be connected to the telescopic end of the lifting component so that the distance between the blade wheel 2 and the glass can be adjusted, thereby enabling the blade wheel 2 to contact the glass to cut the glass when the mounting portion moves.

[0073] See also Figure 7 In some embodiments, the cutting device further comprises a flexible support portion 14, a pressure portion 28 and a pulling component. The flexible support portion 14 is arranged on one side of the platform 3 along a direction perpendicular to the extension direction of the slide rail 4, the length direction of the flexible support portion 14 is parallel to the extension direction of the slide rail 4, the pressure portion 28 is movably connected to the seat body 5 along a first direction perpendicular to the length direction of the flexible support portion 14, the pressure portion 28 is used to make the flexible support portion 14 partially away from the platform 3, and the pulling component is used to make the flexible support portion 14 straight.

[0074] A spring may be provided between the pressure-applying portion 28 and the seat body 5 to provide an elastic force for returning the pressure-applying portion 28 to its original position.

[0075] The length direction of the flexible support portion 14 may be the direction shown by the X-axis in the figure, the first direction may be the direction shown by the Z-axis in the figure, and the first direction may also be perpendicular to the platform 3 .

[0076] When the flexible support part 14 is stretched straight, the top surface of the flexible support part 14 can be set flush with the top surface of the platform 3. When the glass is placed on the platform 3, the flexible support part 14 is set under the glass. The flexible support part 14 contacts the glass, which increases the friction between the glass and the platform 3, thereby reducing the risk of the glass slipping relative to the platform 3.

[0077] It should be noted that, in this embodiment, the position of the slide rail 4 relative to the platform 3 needs to avoid the flexible support portion 14. In terms of distance, the slide rail 4 can be slightly higher than the placement surface of the platform 3 so that the glass can contact the platform 3 and the flexible support portion 14 at the same time.

[0078] The pressure-applying portion 28 applies pressure to the flexible support portion 14 . Specifically, when the glass is placed on the platform 3 and the flexible support portion 14 is disposed below the glass, the pressure-applying portion 28 can push the flexible support portion 14 to move downward.

[0079] The pressure applying portion 28 can be arranged corresponding to the position of the cutter wheel 2 .

[0080] The pressure portion 28 enables the flexible support portion 14 to partially avoid the glass, that is, when the cutter wheel 2 cuts the glass, the flexible support portion 14 is partially pushed away by the pressure portion 28 , reducing the risk of the flexible support portion 14 being damaged by the cutter wheel 2 .

[0081] A spring may be provided between the pressure applying portion 28 and the seat body 5 .

[0082] The pressure-applying part 28 can also play a role in further separating the two parts of the glass after being cut. Specifically, after the glass is cut, the flexible support part 14 is pulled to move by the pulling component so that the flexible support part 14 can be stretched straight. When the flexible support part 14 is stretched straight, the pressure-applying part 28 is pushed to move toward the seat body 5, and the flexible support part 14 can approach the cutting groove of the glass. As the flexible support part 14 approaches the cutting groove, the flexible support part 14 can form a force to move the two parts of the glass away from each other, that is, the two parts of the glass formed after being cut can be further separated by the flexible support part 14, so that the two parts can be removed from the platform 3 respectively.

[0083] The material of the flexible support portion 14 can be selected from existing materials, which will not be described in detail here.

[0084] In some embodiments, the traction component includes two traction rollers 30 . The two traction rollers 30 are rotatably disposed on both sides of the platform 3 along the length direction of the flexible support portion 14 , and both ends of the flexible support portion 14 are respectively wound around the two traction rollers 30 .

[0085] When the traction roller 30 unwinds the flexible support part 14, the length of the flexible support part 14 between the two traction rollers 30 increases, so that the pressure-applying part 28 can push the flexible support part 14 to move partially away from the platform 3. When the traction roller 30 rewinds the flexible support part 14, the flexible support part 14 can be in a straightened state, and the flexible support part 14 can exert a force on the glass to move away from each other.

[0086] The driving structure of the traction roller 30 can be selected from existing structures and will not be described in detail here.

[0087] In some embodiments, the pressure applying portion 28 includes a first side close to the flexible support portion 14 , and a contact roller 29 is rotatably disposed on the first side.

[0088] The contact roller 29 can reduce the friction between the pressure-applying portion 28 and the flexible support portion 14 , thereby reducing the risk of the pressure-applying portion 28 damaging the flexible support portion 14 when the seat 5 drives the pressure-applying portion 28 to move relative to the flexible support portion 14 .

[0089] So far, various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described.
