Description

Technical Field

[0001] The present invention belongs to the technical field of sheet cutting, and particularly relates to a visual positioning cutting device. Background Art

[0002] Basic background; When a plate shearing machine is used in plate production, it is for the purpose of fixed-distance and cutting of plates. The principle is that the plate is conveyed through a roller path, and an optoelectronic sensor fixed on the roller path senses whether the plate reaches the set length. After the induction is triggered, the plate shearing machine works to achieve fixed-distance cutting of the plate; However, it is found in actual use that the optoelectronic sensor requires extremely high precision during installation, and the plates need to be cut into different lengths according to different batch requirements. Therefore, the optoelectronic sensor needs to be adjusted with high precision every time. Its difficulty and accuracy are poor, and the adjustment time required is also long, which is not conducive to efficient cutting; To solve the above problems, a visual positioning cutting device is proposed in this application.

[0010] Further, the pressing roller is rotatably installed on one side of the upper end of the conveying frame away from the vision detection system.

[0011] Further, an operation cabinet is installed on the side of the guillotine shear, and the operation cabinet is electrically connected to the guillotine shear motor, the conveying motor, the electric cylinder, and the vision detection system.

[0012] Further, when the vision detection system recognizes the Mark point, during the process of the operation cabinet transmitting a signal, the servo positioning mechanism conveys the Mark point directly below the guillotine shear and stops.

[0013] Further, the vision detection system is fixed to the upper end of the guillotine shear through a bracket, and the shooting direction of the vision detection system and the movement path of the plate are vertically distributed.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0019] Please refer to Figures 1-5 As shown, the present invention is a visual positioning cutting device, including a guide roller path 1 for conveying a plate 8 and a plate shearing machine 2 installed on the guide roller path 1 and used for cutting the plate 8. The plate shearing machine 2 cuts the whole plate 8 by punching. A visual inspection system 3 capable of collecting the Mark point 81 on the side of the plate 8 is installed on the plate shearing machine 2. When the visual inspection system 3 recognizes the Mark point 81, during the process of the control cabinet 7 transmitting a signal command, the servo positioning mechanism 5 transports the Mark point 81 to directly below the plate shearing machine 2 and stops. A conveyor frame 4 is provided near the input end of the plate 8 of the plate shearing machine 2. A servo positioning mechanism 5 and a pressing roller 6 for pressing and conveying the plate 8 are provided on the conveyor frame 4. The path of the plate passing through is the pressing roller 6, the servo positioning mechanism 5, the visual inspection system 3, and the plate shearing machine 2 in sequence.

[0020] Among them, the plate shearing machine 2 includes a half-frame 21 and a cutting knife 22 that slides vertically on the half-frame 21, as well as a cam 23 rotatably installed on the half-frame 21. The bottom of the cutting knife 22 is provided with a contact end that contacts the cam 23. The cam 23 is installed on the half-frame 21 through a connecting shaft. When the protruding part of the cam 23 rotates upward, it pushes the cutting knife 22 upward to achieve the cutting action of the plate. When the protruding part moves downward, the cutting knife 22 moves downward under the action of gravity.

[0021] Among them, the plate shearing machine 2 further includes a plate shearing motor 24 fixed to the bottom of the half-frame 21 and a belt drive 25 arranged between the plate shearing motor 24 and the cam 23. The belt drive 25 is a servo motor. The belt drive 25 is composed of a synchronous pulley and a synchronous belt, and tooth transmission is adopted between them to avoid slipping and affecting the transmission effect. The servo motor enhances the cutting accuracy.

[0022] Among them, the servo positioning mechanism 5 includes a mounting frame 51 fixed on the conveying frame 4 and a lower roller 52 rotatably arranged at the lower end of the mounting frame 51. The upper end of the mounting frame 51 is provided with a movable upper roller 54 through an electric cylinder 55. The upper roller 54 is located directly above the lower roller 52.

[0023] Among them, sliding members 53 are provided between the two ends of the upper roller 54 and the mounting frame 51 in the vertical direction. The sliding members 53 are composed of a sliding seat and a sliding rail that are slidably matched with each other. The upper roller 54 is rotatably installed on the sliding seat, and the sliding rail is fixed to the inner side wall of the mounting frame 51. The plate 8 is clamped between the lower roller 52 and the upper roller 54 and is conveyed under the action of the conveying motor 56.

[0024] Among them, a sunk groove for installing the servo positioning mechanism 5 is opened on one side of the upper end of the conveying frame 4. The top of the conveying frame 4 and the lower roller 52 are in contact with the lower surface of the plate 8. The sunk groove plays a role of avoidance to ensure that the plate 8 passes through in a horizontal posture.

[0025] Among them, the pressure roller 6 is rotatably installed on one side of the upper end of the conveying frame 4 away from the visual inspection system 3. The pressure roller 6 is used to press the plate 8 before it is conveyed by the conveying frame 4 to prevent the deformed plate 8 from being conveyed by the conveying frame 4 and affecting the accuracy.

[0026] Among them, an operation cabinet 7 is installed on the side of the plate shearing machine 2. The operation cabinet 7 is electrically connected to the plate shearing motor 24, the conveying motor 56, the electric cylinder 55, and the visual inspection system 3.

[0027] Among them, when the visual inspection system 3 recognizes the Mark point 81, during the process of the operation cabinet 7 transmitting a signal command, the servo positioning mechanism 5 conveys the Mark point 81 directly below the plate shearing machine 2 and stops.

[0028] Among them, the visual inspection system 3 is fixed to the upper end of the plate shearing machine 2 through a bracket, and the shooting direction of the visual inspection system 3 and the moving path of the plate 8 are vertically distributed. The vertical setting ensures accurate recognition.

[0029] It can be understood that the present invention identifies the Mark point spacing on the sheet through a visual detection system, and through the coordinated control of the operation cabinet, realizes the automatic cutting of the shearing machine and the precise stop of the servo positioning mechanism. At the same time, the servo positioning mechanism uses an electric cylinder to adjust the height of the upper roller to adapt to different sheet thicknesses, with the advantages of high-precision cutting, stable conveying, and convenient adjustment.

[0030] A specific application of this embodiment is as follows: Figures 1-2 As shown, the sheet 8 is conveyed from right to left. After the lower movement of the electric cylinder 55, the upper roller 54 cooperates with the mounting frame 51 to press the sheet 8, and then the sheet 8 is conveyed through the drive of the conveying motor 56. During the process of the sheet 8 passing through the shearing machine 2 and the visual detection system 3, the visual detection system 3 can identify the Mark point 81. When the Mark point 81 is identified by the visual detection system 3, the signal is transmitted to the operation cabinet 7. The operation cabinet 7 stops the conveying of the servo positioning mechanism 5 and starts the shearing machine 2. During the signal transmission process, the servo positioning mechanism 5 does not stop immediately, so the Mark point 81 can be sent to the position of the shearing machine 2. Then, the shearing machine 2 performs a cutting operation. After the cutting is completed, the operation cabinet 7 receives the instruction and makes the servo positioning mechanism 5 work again until the visual detection system 3 identifies the next Mark point 81 for another cutting operation.
