Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
The utility model discloses a first embodiment relates to a fold detection device of cutter, specifically as shown in fig. 1 ~ 3, contains: the cutting table comprises a cutting table 1, a machine head walking mechanism 2, a machine head 3, two infrared light emitters 4, two infrared light receivers 5, a controller 6, a communication device 7 and an indicator light 8.
Wherein, the cutting table 1 is used for laying materials to be cut; two ends of the machine head travelling mechanism 2 are respectively movably connected with two sides of the cutting table 1 and can move along the side edge of the cutting table 1; be equipped with cut-off knife 9 on the aircraft nose 3, aircraft nose 3 can move along the length direction of tailoring platform 1 along aircraft nose running gear 2, and aircraft nose 3 can move along the width direction of tailoring platform 1 on aircraft nose running gear 2, treats to tailor the material and tailors.
Two infrared light outer emitters 4 are arranged at one end of the machine head travelling mechanism 2, and two infrared light receivers 5 are arranged at the other end of the machine head travelling mechanism 2. On one hand, the two infrared light emitters 4 and the two infrared light receivers 5 can synchronously move along with the machine head travelling mechanism 2, and whether wrinkles exist at the position to be cut of the material is detected in real time; on the other hand, the infrared light emitted by the two infrared light emitters 4 can cover the position where the cutting knife 9 is located, and the fold detection omission can be avoided.
The two infrared light emitters 4 are point light sources and are used for emitting point-like infrared light beams, and the cut-off knife 9 is positioned between the infrared light emitted by the two infrared light emitters 4. That is, the two infrared light emitters 4 are respectively located at two sides of the cutting knife 9, and the two infrared light receivers 5 are also respectively located at two sides of the cutting knife 9; the positions of the infrared light emitters 4 and the infrared light receivers 5 correspond to each other one by one. In other words, a pair of infrared light emitter 4 and infrared light receiver 5 are respectively disposed on each side of the cutting knife 9, each pair of infrared light emitter 4 and infrared light receiver 5 is disposed opposite to each other and on the same axis, and constitutes a detecting portion 10, and the infrared light receiver 5 is used for receiving the infrared light emitted by the infrared light emitter 4. When there is a wrinkle on the light path between each pair of infrared light emitter 4 and infrared light receiver 5 and the wrinkle blocks the infrared light, the infrared light receiver 5 does not receive the infrared light.
Moreover, in general, the distance between the infrared light emitted from each infrared light emitter 4 and the cutting knife 9 may be in a range of 10 to 20 mm. Preferably, in the present embodiment, the distance range from the infrared light emitted by each infrared light emitter 4 to the cutting knife 9 is 10 mm. Because the folds have a certain length and continuity, if the folds are detected at a position 10 mm away from the cutter, the folds at the cutting position of the material to be cut are considered to exist, so that the folds with short length close to the cutter 9 can be detected, the folds with short length can be prevented from being missed, the cutting quality is further improved, and the loss is reduced.

Generally, the predetermined height may be 10 to 20 mm. Preferably, in the present embodiment, the preset height is 10 mm. In this way, the folds with lower projections can also be detected, so that the cutting quality can be improved, and the loss can be reduced.

Namely, the two infrared light receivers 5 and the handpiece traveling mechanism 2 are electrically connected with the controller 6. Wherein, the controller 6 comprises an infrared correlation sensor 61 and a control chip 62; the infrared correlation sensor 61 is electrically connected to the two infrared light receivers 5 and the control chip 62, respectively.

Therefore, the problem that the cutting quality is low due to the fact that the cutting materials are convex in the cutting process can be avoided, the defective rate is reduced, the materials are saved, and the loss is reduced.
The communication device 7 is electrically connected to the controller 6. The controller 6 sends out the detection result of the controller 6 through the communication device 7 in real time so as to be known by staff and take corresponding measures. In practical applications, the communication device 7 may be a wired communication device or a wireless communication device. Preferably, in the present embodiment, the communication device 7 is a wireless communication device. Thus, wiring can be reduced, and space and cost can be saved.
The indicator light 8 is electrically connected with the controller 6 and used for lighting or flashing under the control of the controller 6 when the wrinkles are detected so as to attract the attention of workers, and the cutting machine with the wrinkles detected can be conveniently and rapidly locked by the workers and can be timely processed.

When the cutting machine cuts a material, the two infrared emitters 4 emit infrared light at the same time, if any one side of the cutter 9 has a fold and the height of the fold is higher than a preset height, namely if any one infrared receiver 5 cannot receive the infrared light, the controller 6 controls the machine head traveling mechanism 2 to stop moving and the machine head 3 to stop cutting. Therefore, the problem that the cutting quality is low due to the fact that the cutting materials are convex in the cutting process can be avoided, the defective rate is reduced, the materials are saved, and the loss is reduced.
