[0044] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0046] See Figure 1 The material strip cutting apparatus of this disclosure embodiment will be described as shown.

[0047] The strip cutting device of this disclosure includes a conveying mechanism 1, a scanner, an information acquisition mechanism 3, a cutting mechanism 4, and a controller 5.

[0048] The conveying mechanism 1 is used to convey the material belt 6 along the length direction of the material belt 6, which includes various patterns spaced apart along the length direction.

[0049] In this embodiment, the conveying mechanism 1 can be a conveyor belt. For example, a material belt 6 is placed on the conveyor belt, and the conveyor belt moves as the pulleys rotate, allowing the material belt 6 on the conveyor belt to move along its length. The conveying mechanism 1 can also be a clamp that pulls one end of the material belt 6. For example, the clamp can include a movable clamp 12, which moves along the length of the material belt 6 and approaches one end of the material belt 6. The movable clamp 12 then clamps the material belt 6, and subsequently, the movable clamp 12 can pull the material belt 6 to move along its length. The conveying mechanism 1 can also be other mechanisms capable of driving the material belt 6 to move along its length; no limitation is made here.

[0050] Scanner 2 is used to scan a first section of the material strip 6 at a first set position. The first section is the section of the material strip 6 that is within the scanning range of scanner 2.

[0051] In this embodiment, the scanner 2 is, for example, a barcode scanner or a camera, etc., and is not limited to this.

[0052] Information collection mechanism 3 is used to collect material belt information of material belt 6 at a second set position.

[0053] In this embodiment, the information acquisition device 3 is, for example, a color mark sensor or a camera, etc., and is not limited here.

[0054] The cutting mechanism 4 is used to cut the material strip 6 at a third set position; wherein, in the conveying direction of the material strip 6, the third set position is located in front of the first set position and the second set position.

[0055] In some examples, the cutting mechanism 4 can control the cutting blade to cut the strip 6 in different ways. For example, the cutting blade can cut the strip 6 in a direction perpendicular to the length of the strip 6, or the cutting blade can rotate around the handle to cut the strip 6, etc.

[0056] by Figure 1 For example, the cutting mechanism 4 can move along a direction perpendicular to the length of the strip 6, so that the cutting blade of the cutting mechanism 4 can cut the strip 6 at the third set position D3.

[0057] The controller 5 can be electrically connected to the conveying mechanism 1, the scanner 2, the information acquisition mechanism 3, and the cutting mechanism 4 respectively, or can be communicatively connected to the conveying mechanism 1, the scanner 2, the information acquisition mechanism 3, and the cutting mechanism 4 respectively, so that the controller 5 can control the operation of the conveying mechanism 1, the scanner 2, the information acquisition mechanism 3, and the cutting mechanism 4.

[0058] In this embodiment, the controller 5 is, for example, a programmable logic controller (PLC), etc., and is not limited to this.

[0059] The controller 5 is configured to control the scanner 2 to scan the first section of the material belt 6 when the conveying mechanism 1 completes one conveying of the material belt 6 according to the set first step width; when the scanning result fed back by the scanner 2 indicates that the material belt 6 is deviated, the controller 5 controls the conveying mechanism 1 to convey the material belt 6 at the set second step width, and controls the information acquisition mechanism 3 to collect the material belt information and perform material belt 6 deviation correction; when the material belt information fed back by the information acquisition mechanism 3 indicates that the material belt 6 deviation correction is in place, the controller 5 controls the conveying mechanism 1 and the information acquisition mechanism 3 to stop operating, and controls the cutting mechanism 4 to cut the second section of the material belt 6 before the third set position, thus completing the material belt 6 deviation correction.

[0060] In some examples, such as Figure 1 As shown, the material belt 6 can move in the first step under the action of the conveying mechanism 1, first passing the first set position D1 below the scanner 2. When the scanner 2 feeds back the scanning result that the first set position D1 has deviated to the controller 5, the material belt 6 moves in the second step under the action of the conveying mechanism 1. The controller 5 controls the information acquisition mechanism 3 to collect the material belt information at the first set position D2. When the controller 5 receives the material belt information fed back by the information acquisition mechanism 3 indicating that the material belt 6 has been corrected, it can control the conveying mechanism 1 and the information acquisition mechanism 3 to stop operating, and then control the cutting mechanism 4 to cut the second section of the material belt 6 before the third set position D3 to complete the correction of the material belt 6.

[0061] In some examples, the controller 5 can control the aforementioned servo motor to adjust the moving distance of the material belt 6. That is, when the scanning result fed back by the scanner 2 indicates that the material belt 6 is off-center, the controller 5 controls the servo motor to enter the Guide mode and deliver the material belt 6 with a second step of a set smaller step size, so as to cooperate with the information acquisition mechanism 3 to collect the material belt information, thereby realizing the correction of the material belt 6.

[0062] In other words, as the material belt 6 moves forward in the first step, the scanner 2 can scan the material belt 6. If the scanning result shows that the material belt 6 is off-center, the information acquisition mechanism 3 and the conveying mechanism 1 can be controlled to cooperate to correct the deviation of the material belt 6, thereby improving the cutting accuracy of the material belt 6 and thus improving the quality of the cut products.

[0063] In some embodiments, in order to convey the material belt 6, the conveying mechanism 1 may include: an unwinding assembly, which is disposed on the side of the scanner 2 away from the information acquisition mechanism 3, and is used to store the material belt 6 to be conveyed; and a belt pulling assembly, which is disposed on the side of the information acquisition mechanism 3 away from the scanner 2, and is used to pull the material belt 6 to move in a first step or a second step.

[0064] by Figure 2 For example, the unwinding assembly is the unwinding roller 11 of the winding strip 6, through which the strip 6 can be fed to the scanner 2. The belt pulling assembly can pull the strip 6, so that the strip 6 can move from the unwinding roller 11 toward the scanner 2.

[0065] In some embodiments, such as Figure 2 As shown, in order for the material strip 6 to move in a first step or a second step, the belt pulling assembly includes a moving clamp 12 and a fixed clamp 13. The moving clamp 12 and the fixed clamp 13 are respectively disposed on both sides of the cutting mechanism 4. The controller 5 is further configured to control the moving clamp 12 to clamp the material strip 6 at a first set clamping position and move it to a second set clamping position to pull the material strip 6 along the length direction of the material strip 6. The controller 5 is also configured to control the moving clamp 12 and the fixed clamp 13 to clamp the material strip 6 before controlling the cutting mechanism 4 to cut the material strip 6.

[0066] In some examples, the moving clamp 12 may include a directional movement structure and a pneumatic gripper. The directional movement structure is a combination of a servo motor, a gear, and a rack. That is, a gear that meshes with a rack is provided on the output shaft of the servo motor. One end of the rack can be fixed to the pneumatic gripper. The rack can slide along the length of the strip 6 on the support of the strip cutting device, so that the rotation of the output shaft of the servo motor can drive the rack to move, thereby enabling the moving clamp 12 to pull the strip 6 to move.

[0067] In some examples, the fixed clamp 13 can be a pneumatic gripper, which can be of the same type as the pneumatic gripper of the movable clamp 12 or a different type, without limitation.

[0068] In some embodiments, in order to make the material strip 6 flatter during cutting, the conveying mechanism 1 further includes a tensioning component 7; the tensioning component 7 is disposed between the unwinding component and the scanner 2, and the tensioning component 7 drives the third section of the material strip 6 located between the unwinding component and the scanner 2 to extend along a set extension direction; wherein, the extension direction is set perpendicular to the length direction of the material strip 6.

[0069] by Figure 2 For example, the tensioning assembly 7 includes a tensioning cylinder 70, a fifth tensioning roller 75, a sixth tensioning roller 76, and a seventh tensioning roller 77. The material strip 6 can be wound around the fifth tensioning roller 75, the sixth tensioning roller 76, and the seventh tensioning roller 77 in sequence. The piston rod of the tensioning cylinder 70 is connected to the sixth tensioning roller 76, so that the piston rod of the tensioning cylinder 70 can extend and push the sixth tensioning roller 76 to move in the extension direction to tension the material strip 6.

[0070] In some embodiments, such as Figure 2 As shown, the tensioning assembly 7 may include a first tensioning roller 71, a second tensioning roller 72, a third tensioning roller 73, and a fourth tensioning roller 74. The first tensioning roller 71 is disposed between the fifth tensioning roller 75 and the unwinding roller 11. The second tensioning roller 72 is disposed between the scanner 2 and the seventh tensioning roller 77. The third tensioning roller 73 and the fourth tensioning roller 74 may be disposed between the scanner 2 and the information acquisition mechanism 3 to further tension the material belt 6.

[0071] In some embodiments, such as Figure 3 As shown, color mark points are set between adjacent patterns in the material strip 6, and the information acquisition mechanism 3 is a color mark detection sensor; the material strip information fed back by the information acquisition mechanism 3 indicates that the material strip 6 has been corrected in place, including: the material strip information fed back by the information acquisition mechanism 3 indicates that the color mark point has been collected at the second set position.

[0072] by Figure 3 For example, the conveying mechanism 1 conveys the material belt 6 with the second stride. The material belt 6 moves from right to left. The material belt information fed back by the information acquisition mechanism 3 to the controller 5 is that the color mark point is collected at the second set position, that is, the material belt 6 is corrected in place. The controller 5 can control the cutting mechanism 4 to cut off the section of the material belt 6 before the third set position.

[0073] In other words, by using a color mark detection sensor for alignment, controller 5 can respond quickly to perform the next cut.

[0074] In some embodiments, the controller 5 is configured to control the cutting mechanism 4 to cut the material strip 6 when the scanning result fed back by the scanner 2 indicates that the material strip 6 has not deviated; the controller 5 is also configured to control the conveying mechanism 1 to continue conveying the material strip 6 according to the set first step width when the cutting mechanism 4 feeds back the cutting completion information.

[0075] In some examples, using a QR code as an example, scanner 2 can scan the QR code and, if the scan is successful, send a scan result to controller 5 indicating that the material strip 6 has not shifted. Upon receiving this scan result, controller 5 can control cutting mechanism 4 to cut the material strip 6.

[0076] In some embodiments, the strip cutting device further includes a receiving mechanism 8, which is used to restrict the movement of the strip 6 at a fourth set position. The receiving mechanism 8 is located on the side of the information acquisition mechanism 3 away from the barcode scanner. The controller 5 is also used to control the action of the receiving mechanism 8. The controller 5 is also configured to control the receiving mechanism 8 to limit the strip 6 before controlling the cutting mechanism 4 to cut the strip 6.

[0077] In this embodiment, the fourth set position is, for example, Figure 1 At the fourth set position D4, the receiving mechanism 8 restricts the movement of the material belt 6 by suction or clamping at the fourth set position D4.

[0078] In some embodiments, the controller 5 is further configured to, if the scanning result fed back by the scanner 2 indicates that the strip 6 has deviated, control the take-up mechanism 8 to transport the third segment of the strip 6 before the third set position to the set scrap area; the controller 5 is further configured to, after controlling the cutting mechanism 4 to cut the second segment of the strip 6 before the third set position, control the take-up mechanism 8 to transport the second segment to the set scrap area; the controller 5 is further configured to, if the scanning result fed back by the scanner 2 indicates that the strip 6 has not deviated, control the take-up mechanism 8 to transport the third segment of the strip 6 before the third set position to the set good product area.

[0079] In this embodiment, the waste area and the good product area can be areas that are pre-defined by humans, and there is no limitation here.

[0080] In other words, the receiving mechanism 8 can send the second and third sections of the material belt 6 to the corresponding areas to distinguish between good and bad products from the sections cut off from the material belt 6, thereby reducing the workload of manually screening the cut sections.

[0081] In some embodiments, the receiving mechanism 8 includes an adsorption block 81 and a moving component 82, the moving component 82 being connected to the adsorption block 81. The controller 5 controls the movement of the adsorption block 81 and the moving component 82. The controller 5 is also configured to move the third segment of the material strip 6 adsorbed by the adsorption block 81 to the waste area or the good area via the moving seat. The controller 5 is also configured to move the second segment of the material strip 6 adsorbed by the adsorption block 81 to the waste area via the moving seat. The controller 5 is also configured to control the adsorption block 81 to limit the second segment or the third segment of the material strip 6.

[0082] In this embodiment, the moving component 82 is, for example, a robotic arm, which allows the adsorption block 81 to be moved to the waste area or the good area.

[0083] In other words, by setting up the adsorption block 81 and the moving component 82 in cooperation, the limiting and conveying of the cut section of the material strip 6 can be realized, thereby realizing the intelligentization of the material strip cutting device.

[0084] In some embodiments, the strip cutting device further includes a processing mechanism 9, which is located on the side of the receiving mechanism 8 away from the information collection mechanism 3; the controller 5 is also configured to control the processing mechanism 9 to process the fourth section of the strip 6 located in the good product area after controlling the receiving mechanism 8 to transport the third section of the strip 6 to the set good product area before the third set position.

[0085] In some examples, taking the pattern as a QR code, the processing mechanism 9 can be a labeling mechanism, and the receiving mechanism 8 can send a section of the good product material strip 6 to the good product area of ​​the processing mechanism 9, so that the processing mechanism 9 can detect that there is a new section of material strip 6 in the good product area, and perform labeling processing on the section to realize the intelligentization of the material strip cutting device.
