When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The present invention provides a cutting device, which aims to ensure that a cutting group can cut products quickly and accurately while realizing automatic alignment of the cutting device.

[0035] The specific structure of the cutting device proposed by the present invention will be described in the following specific embodiments:

[0036] In the technical solution of this embodiment, Figure 1 As shown, the cutting device 100 includes a machine platform 10 and an alignment group 30, wherein the machine platform 10 has a processing station; the alignment group 30 includes a frame 31, a camera 32 and a focal length extension member 33 for extending the transmission distance of light, wherein the frame 31 is movably arranged on the machine platform 10, the focal length extension member 33 and the camera 32 are respectively arranged on the frame 31, the lens of the camera 32 is arranged toward one end of the focal length extension member 33, and the other end of the focal length extension member 33 is arranged toward the processing station, wherein the imaging light 321 of the lens of the camera 32 is emitted from the processing station through the turning of the focal length extension member 33 to the lens of the camera, so that the camera 32 is focused on the processing station.

[0037] It can be understood that by setting a focal length extension member 33 on the frame 31, the path of the imaging light of the camera 32 can be extended and the focal length can be extended, so that the camera 32 can be used to identify the product in a relatively limited space to achieve automatic alignment, while ensuring that the cutting group 20 can cut the product quickly and accurately.

[0038] Specifically, the alignment group 30 includes a frame 31, a camera 32, and a focal length extension member 33 for extending the transmission distance of light. The machine 10 has a processing station, and the frame 31 is movably arranged on the machine 10. When positioning is required, the frame 31 is moved on the machine 10 to move the camera 32 and the focal length extension member 33 to the top of the product on the processing station for positioning operation. The focal length extension member 33 and the camera 32 are respectively arranged on the frame 31, the lens of the camera 32 is arranged toward one end of the focal length extension member 33, and the other end of the focal length extension member 33 is arranged toward the upper surface of the machine 10. The imaging light 321 is transmitted from the product on the processing station to the focal length extension member 33 from one end, and is emitted from the other end of the focal length extension member 33 to the lens of the camera 32, and the imaging light 321 is captured by the lens of the camera 32, so that the product on the processing station is imaged on the camera 32; and the product is photographed.

[0039] In a feasible manner, multiple reflective elements are arranged in the focal length extension member 33, and the imaging light 321 is reflected by the multiple reflective elements to form multiple light transmission channels in the vertical direction. The imaging light 321 is transmitted from the product on the processing station to one port of the transmission channel, and is emitted into the transmission channel from the port, and finally emitted from the other port of the transmission channel to the lens of the camera 32; at a limited height distance (the distance between the cutting group 20 and the processing station), the imaging light 321 reciprocates through the transmission channel, thereby realizing long-distance transmission of the imaging light 321, so that the camera 32 set within a limited height can focus on the product on the processing station, while ensuring that the cutting group 20 can quickly and accurately cut the product, and realizing automatic alignment of the cutting device 100.

[0040] In the technical solution of this embodiment, the focal length extension has a first transmission port 331, an expansion space 332 for expanding the transmission distance of light, and a second transmission port 333. The first transmission port 331 and the second transmission port 333 are connected through the expansion space 332. The lens of the camera 32 faces the first transmission port 331, and the second transmission port 333 faces the processing station. A turning element is provided in the expansion space 332 to turn the imaging light 321 in the expansion space 332 through the turning element to increase the transmission distance of the imaging light 321. The imaging light 321 is emitted into the expansion space 332 through the second transmission port 333 and is emitted from the first transmission port 331 to the lens of the camera 32 after being turned by the turning element in the expansion space 332.

[0041] It can be understood that by setting a turning element in the expansion space 332, a plurality of interconnected transmission channels are formed in the expansion space 332 through the turning element, and the imaging light 321 is transmitted in the plurality of transmission channels, so that the imaging light 321 can be transmitted over a longer distance within a limited height, thereby achieving long-distance transmission of the imaging light 321 under a limited height, and thus enabling the camera 32 to focus on the product at the processing station and take clear pictures of the product.

[0042] Specifically, the focal length extension member 33 has a first transmission port 331, an expansion space 332 for extending the transmission distance of light, and a second transmission port 333; the first transmission port 331 is connected to the second transmission port 333 through the expansion space 332; the lens of the camera 32 faces the first transmission port 331, and the imaging light 321 in the expansion space 332 is transmitted to the lens of the camera 32 through the first transmission port 331, and the imaging light 321 is repeatedly turned by the turning element in the expansion space 332 to achieve long-distance transmission of the imaging light 321 at a limited height; the second transmission port 333 faces the processing station, and the imaging light 321 is emitted from the second transmission port 333 into the expansion space 332, and the camera 32 focuses and shoots the product on the processing station to achieve rapid alignment of the product.

[0043] The transmission path of the imaging light 321 is as follows: the imaging light 321 of the camera 32 is emitted from the processing station through the second transmission port 333 into the expansion space 332, and after turning through the expansion space 332, is emitted from the first transmission port 331 to the lens of the camera 32, so that the camera 32 is focused on the product at the processing station.

[0044] In the technical solution of the present embodiment, one end of the focal length extension member 33 is connected to the frame 31, and the other end extends toward the direction of the processing station; a cavity is formed in the focal length extension member 33, and the cavity is the expansion space 332; a first transmission port 331 is opened on the upper surface of the focal length extension member 33, and is located at one end of the focal length extension member 33 fixed on the frame 31; a second transmission port 333 is opened on the lower surface of the focal length extension member 33, and is located at the other end of the focal length extension member 33, and the first transmission port 331 and the second transmission port 333 are respectively connected to the expansion space 332; the focal length extension member 33 is provided with a first turning element 334 at the position of the first transmission port 331, which is used to turn the imaging light 321 from the first transmission port 331 to the lens of the camera 32; the focal length extension member 33 is provided with a second turning element 335 at the position of the second transmission port 333, which is used to turn the imaging light 321 from the processing station to the expansion space 332, and the first turning element 334 and the second turning element 335 are arranged in parallel.

[0045] It can be understood that in order to simply extend the transmission distance of the imaging light 321, by connecting one end of the focal length extension piece 33 to the frame 31 and extending the other end toward the direction of the punching processing station, a cavity is formed in the focal length extension piece 33, and the cavity is an expansion space 332. Without the need for multiple turning elements, the transmission distance of the imaging light 321 can be extended under limited height conditions. The camera 32 can be located outside the processing station, and will not be damaged during the cutting process. A first transmission port 331 is provided on the upper surface of the focal length extension member 33. The first transmission port 331 is located at one end of the focal length extension member 33 fixed on the frame 31, so that the imaging light 321 of the camera 32 can be emitted from the first transmission port 331 to the lens of the camera 32. The focal length extension member 33 is provided with a first turning element 334 corresponding to the first transmission port 331. The imaging light 321 can be turned from the expansion space 332 to the lens of the camera 32 through the first turning element 334. A second transmission port 333 is provided on the lower surface of the focal length extension member 33. The second transmission port 333 faces the processing The second transmission port 333 is located at the other end of the focal length extension member 33. The focal length extension member 33 is provided with a second turning element 335 corresponding to the second transmission port 333, which is used to turn the imaging light 321 from the processing station to the expansion space 332. The first turning element 334 and the second turning element 335 are arranged in parallel. The imaging light 321 is transmitted along the length direction of the expansion space 332, so that in the case of limited height, the transmission distance of the imaging light 321 is extended, the imaging position of the camera 332 is expanded, and the camera 32 is focused on the product on the processing station.

[0046] In the technical solution of this embodiment, the focal length extension member 33 is arranged on the frame 31 perpendicular to the shooting direction of the lens of the camera 32, the first turning element 334 has a first reflecting surface 334A, the first reflecting surface 334A is located below the first conveying port 331, and is arranged at an angle of 45° to the first conveying port 331, and the second turning element 335 has a second reflecting surface 335A, the second reflecting surface 335A is located above the second conveying port 333, and is arranged at an angle of 45° to the second conveying port 333.

[0047] It can be understood that, in order to facilitate design and assembly, the focal length extension member 33 is arranged on the frame 31 perpendicular to the shooting direction of the camera 32, and the first turning element 334 has a first reflection surface 334A, which is located below the first transmission port 331 and is arranged at an angle of 45° to the first transmission port 331. Figure 4As shown, the angle between the first reflection surface 334A and the lower surface of the focal length extension member 33 is defined as A, and the condition A is equal to 45°. The second turning element 335 has a second reflection surface 335A, which is located above the second transmission port 333 and is set at an angle of 45° to the second transmission port 333. The shooting direction of the camera 32 is perpendicular to the upper surface of the focal length extension member 33. The imaging light 321 is perpendicularly incident on the second reflection surface 335A from the processing station toward the second transmission port 333, and is turned 90° from the second reflection surface 335A to the first reflection surface 334A. When the imaging light 321 is perpendicular to the first reflection surface 334A, it is turned 90° through the first reflection surface 334A and is emitted from the first transmission port 331 to the lens of the camera 32. The lens of the camera 32 captures the imaging light 321, and then focuses on the product on the processing station, shoots the product on the processing station, and then performs an automatic positioning operation on the product.

[0048] In the technical solution of this embodiment, the focal length extender 33 is in a rectangular parallelepiped shape, and the first transmission port 331 and the second transmission port 333 are respectively located at two ends of the focal length extender 33 .

[0049] It can be understood that in order to simplify the setting of the focal length extension member 33, the focal length extension member 33 can be set as a rectangular parallelepiped, and the imaging light 321 of the camera 32 can be transmitted from the outside of the processing station to the upper side of the processing station through the rectangular parallelepiped to prevent the problem that the camera 32 cannot focus on the processing station due to the camera 32 being set between the cutting group 20 and the processing station; a cavity is opened in the rectangular parallelepiped, and a first transmission port 331 and a second transmission port 333 are set at both ends of the rectangular parallelepiped.

[0050] In the technical solution of this embodiment, a movable channel is arranged on the frame 31, and the length direction of the movable channel is arranged at an angle with the moving direction of the frame 31. The focal length extension member 33 is inserted in the movable channel and movably arranged in the movable channel along the length direction of the movable channel.

[0051] It can be understood that in order to reduce the space occupied by the focal length extender 33 when the focal length extender 33 is not in use, a movable channel is provided on the frame 31, and the focal length extender 33 is movably arranged in the movable channel. When the focal length extender 33 is used, the focal length extender 33 is moved out of the movable channel, and the end of the focal length extender 33 away from the frame 31 is moved to the upper side of the processing station to align the product on the processing station; when the focal length extender 33 is not in use, the focal length extender 33 is moved into the movable channel, thereby reducing the space occupied by the focal length extender 33 when not in use.

[0052] Specifically, the frame 31 includes a bottom plate, two side plates and a top plate. The two side edges are fixed on the two side edges of the bottom plate. The top plate cover is arranged on the two side plates. The bottom plate, the two side plates and the top plate enclose a moving channel. A supporting frame is arranged on the top plate, and the camera is fixed on the supporting frame.

[0053] In the technical solution of this embodiment, the camera 32 is located above the moving channel, and a through hole is opened on the top wall of the moving channel. The through hole is arranged opposite to the lens of the camera 32, and the through hole is also arranged opposite to the first transmission port 331 for the imaging light 321 of the camera 32 to pass through.

[0054] It can be understood that the camera 32 is fixed on the frame 31 and arranged on the upper side of the movable channel. A through hole is opened on the top wall of the movable channel so that the imaging light 321 of the camera 32 can be emitted from the focal length extension member 33 in the movable channel through the through hole to the lens of the camera 32.

[0055] Specifically, the camera 32 is fixed on the supporting frame, and a through hole is set on the top plate corresponding to the shooting direction of the lens of the camera 32. When the focal length extension member 33 protrudes from the moving channel, the first transmission port 331 of the focal length extension member 33 corresponds to the lower side of the through hole and is connected to the through hole, so that when the imaging light 321 turns out of the first transmission port 331 from the expansion space 332, the imaging light 321 is emitted through the through hole to the lens of the camera 32.

[0056] In a feasible embodiment, the camera 32 can be movably fixed on a support frame, and the support frame is provided with a transmission track along the shooting direction of the camera 32. The camera 32 can be movably arranged on the transmission track. By moving the position of the camera 32 on the support frame, the transmission distance of the imaging light 321 can be actively adjusted so that the camera 32 can be better focused on the processing station.

[0057] In the technical solution of this embodiment, a cylinder 34 is provided on the frame 31 along the length direction of the moving channel, and a piston rod of the cylinder 34 is connected to the focal length extender 33 to drive the focal length extender 33 to move along the length direction of the moving channel.

[0058] It can be understood that in order to achieve automatic positioning, a cylinder 34 is arranged on the frame 31. The cylinder 34 is arranged along the length direction of the moving channel and is used to drive the focal length extender 33 to move along the length direction of the moving channel. The piston rod of the cylinder 34 is connected to the focal length extender 33. When the focal length extender 33 needs to move out of the moving channel, the controller 60 controls the cylinder 34 to work, and the piston rod of the cylinder 34 extends out along the length direction of the moving channel, and drives the focal length extender 33 to move along the length direction of the moving channel toward the outside of the moving channel. After the camera 32 positions the product at the processing station, the controller 60 controls the cylinder 34 so that the piston rod of the cylinder 34 retracts to drive the focal length extender 33 to move toward the moving channel.

[0059] Specifically, the cylinder 34 is disposed on the side plate and connected to the focal length extender 33 in the moving channel.

[0060] In the technical solution of this embodiment, the alignment group 30 also includes a screw transmission member 35, which is arranged on the machine platform 10, and the frame 31 is fixed on the nut slider of the screw transmission member 35 to move along the length direction of the screw rod of the screw transmission member 35.

[0061] It can be understood that by setting a screw transmission member 35 on the machine table 10, the frame 31 is fixed on the nut slider of the screw transmission member 35, so that when the nut slider moves along the length direction of the screw, the frame 31 can move with the nut slider; the length direction of the screw is the transmission direction of the transmission group 40 of the cutting device 100, and the length direction of the screw is perpendicular to the length direction of the moving channel.

[0062] Specifically, the screw transmission member 35 includes a base housing, a screw rod, a driver and a nut slider, the base housing is fixed on the machine table 10, the screw rod is rotatably arranged on the base housing, the driver is fixed on the base housing, and the output shaft of the driver is connected to the screw rod to drive the rotation of the screw rod, the nut slider is movably arranged on the screw rod, and the frame 31 is fixed on the nut slider. The frame 31 moves along the length direction of the screw rod according to the rotation of the screw rod.

[0063] In the technical solution of this embodiment, the cutting device 100 also includes a conveying group 40, which is arranged on the upper surface of the machine table 10, and the alignment group 30 is located on one side of the conveying group 40. The moving direction of the frame 31 and the conveying direction of the conveying group 40 are set in the same direction.

[0064] It can be understood that by setting a conveying group 40 on the upper surface of the machine 10, automatic loading is achieved, the processing station is located on the upper side of the conveying group 40, the alignment group 30 is located on one side of the conveying group 40, and the moving direction of the frame 31 and the conveying direction of the conveying group 40 are set in the same direction, and loading and unloading operations are performed along the moving direction of the frame 31.

[0065] In the technical solution of this embodiment, the conveying group 40 includes a base 41, a transmission member 42 and a pressing member 43. The base 41 is arranged on the machine table, and the transmission member 42 is movably arranged on the base 41; the pressing member 43 is arranged on the upper side of the base 41, and forms a clamping space for clamping the product with the upper surface of the transmission member 42.

The lens of the camera 32 is arranged toward one end of the focal length extension member 33, and the other end of the focal length extension member 33 is arranged toward the processing station.

[0072] The cutting method using the cutting device as described above comprises the following steps:

[0073] S10: Control the conveying group to convey the product to the processing station;

[0074] It can be understood that in the process of cutting products, the conveying group 40 is first opened, and the controller 60 controls the conveying group 40 to convey the product to the processing station on the fine-tuning module 50, and stops the conveying of the conveying group 40 so that the product is located at the processing station.

[0075] S20: Control the alignment group to perform positioning determination on the product on the processing station;

[0076] It can be understood that when the conveying group 40 stops conveying, the product is located at the processing station, the frame 31 of the alignment group 30 is controlled to move to one side of the processing station, and the focal length extension member 33 is controlled to move toward the processing station, so that the first conveying port 331 of the focal length extension member 33 corresponds to the lower side of the lens of the camera 32, and the second conveying port 333 corresponds to the product at the processing station, the camera is turned on, and the product is photographed, and the pre-cutting position of the product is obtained by processing the photo through the processing system. After obtaining the pre-cutting position, the focal length extension member 33 is moved toward the frame 31, the focal length extension member 33 is recovered into the frame 31, and the frame 31 is moved to one side of the cutting group 20 (without affecting the cutting position of the cutting group).

[0077] S30: According to the determination result, the product is adjusted to a standard cutting position by the fine-tuning module, and the cutting head of the cutting group is controlled to cut the product;

[0078] It can be understood that after the frame 31 is moved out, according to the positional relationship between the pre-cutting position and the cutting head 23, the controller 60 controls the fine-tuning module 50 to move along the X-axis and Y-axis directions on the machine 10, so as to correspond the pre-cutting position of the product to the bottom of the cutting head 23, and control the cutting head 23 to cut toward the pre-cutting position of the product to achieve cutting of the product.

[0079] S40: Control the conveying group to convey the finished products out.

[0080] It can be understood that after cutting the product, the cutting head 23 returns to the original position, and the controller 60 controls the conveying group 40 to convey the cut product out of the processing station, thereby completing the cutting of a product. While the conveying group 40 moves out the cut product, it moves the uncut product to the processing station to realize cyclical automated cutting.

[0081] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
