In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0025] As shown in Figure 1 The leather cutting device of the embodiment includes a frame 100, a feeding unit 300, a contour cutting unit and a punching and slicing unit 500 arranged in sequence along the same conveying path are arranged on the frame 100, and the feeding unit 300, the contour cutting unit and the punching and slicing unit 500 are matched with the conveying belt assembly 200. The frame 100 is a spatial rigid structure for bearing and supporting each functional unit. The conveying belt assembly 200 is installed on the frame 100 and is composed of a plurality of conveying belts adjacent to each other. These conveying belts are driven by the same transmission mechanism to run synchronously, thereby realizing smooth conveying of the leather roll between each functional unit. The surface of the conveying belt can be made of high-friction coefficient material to ensure the stability of the leather roll during conveying. The feeding unit 300 is arranged at the most front end of the conveying belt assembly 200. The feeding unit 300 is usually a feeding hub sleeved with the leather roll, which is used to place the large roll of leather roll in the center of the conveying belt. Of course, the feeding unit 300 can also be the output end of the upstream equipment. When the device starts to work, the feeding unit 300 unfolds the front end of the continuous leather sheet and places it in order on the conveying belt, so as to ensure that the leather sheet maintains good flat contact with the conveying belt, facilitating subsequent contour recognition and cutting. The contour cutting unit is located downstream of the feeding unit 300 along the conveying direction of the conveying belt and includes a first CCD camera 410 and a laser emitter 420 as two main components. Figure 2The first CCD camera 410 is fixed above the conveying belt to capture the pattern or cutting information on the surface of the leather roll in real time. The camera is connected to the control system, which can automatically identify the curve, contour line or printed pattern contour of the leather under the cooperation of the program. The laser emitter 420 is installed on the side of the first CCD camera 410, usually on the same beam or bracket, to reduce the influence of relative displacement. The laser emitter 420 is connected to the control system and can automatically adjust the laser emission path and power according to the contour data identified by the camera to achieve accurate contour cutting. When the leather roll is conveyed to the position below the first CCD camera 410 by the conveying belt, the control system receives the real-time image transmitted by the camera, performs pattern analysis and contour identification through the built-in image processing algorithm, and then controls the laser emitter 420 to perform corresponding path cutting according to the identified contour information. The stamping and slicing unit 500 is arranged behind the contour cutting unit and is usually installed in the area between the two continuous conveying belts to separate the large piece of leather that has been contour cut and is still connected together in the form of a roll into single pieces. As shown in the example, Figure 1 The stamping and slicing unit 500 includes an upper die plate 510, a bottom die base 520 and a stamping driving member 530. The upper die plate 510 is located directly above the leather roll and has a cutting edge 511 on the bottom surface that cooperates with the edge line of the piece. The upper die plate 510 is driven by the stamping driving member 530 and can reciprocate vertically. The bottom die base 520 is fixed below the conveying belt to provide stable support for the leather roll. It can be understood that the surface of the bottom die base 520 is provided with a groove hole 521 corresponding to the cutting edge 511. When the upper die plate 510 is pressed down, the cutting edge 511 is inserted into the groove hole 521 of the bottom die base 520, thereby completing the cutting and slicing of the leather roll. The stamping driving member 530 can drive the vertical movement of the upper die plate 510 by using a gas cylinder, a hydraulic cylinder or a mechanical eccentric mechanism. During equipment operation, the large piece of leather that has been contour cut by the contour cutting unit continues to be conveyed by the conveying belt. When the conveying belt reaches the position of the stamping and slicing unit 500, it can be temporarily stopped or slowed down. The stamping driving member 530 immediately acts to make the upper die plate 510 descend, and the cutting edge 511 precisely slices the corresponding area. Then the upper die plate 510 is reset, and the conveying belt continues to rotate to convey the sliced leather pieces to the next process or stacking area. For products with special slicing requirements, different shapes, sizes or knife edge distributions of the upper die plate 510 and the bottom die base 520 can be replaced to adapt to various cutting patterns.
[0026] In an example, when the leather cutting device is used to cut leather, the operator first installs the whole roll of leather raw material to the feeding unit 300 (such as putting the roll of leather into the feeding hub) and sets the appropriate tension; after starting the device, the conveyor belt assembly 200 will sequentially bring the leather roll into the contour cutting unit, the first CCD camera 410 will monitor the leather surface pattern in real time and feed back to the control system, and the laser emitter 420 will perform accurate contour laser cutting on the leather according to the obtained contour data; finally, the leather roll reaches the stamping and slicing unit 500, and the slicing operation is completed by the cooperation of the upper die plate 510 and the bottom die seat 520, thereby obtaining the segmented leather sheet. The whole process has high automation degree, accurate cutting, and can significantly reduce manual intervention.
[0027] In actual production applications, the leather roll is usually composed of two layers, i.e., the leather layer and the plastic carrier tape layer are tightly attached together by adhesive film or other bonding means to form a composite roll. Generally, the material of the carrier tape layer is PET or other thin film material with good heat resistance and dimensional stability, which is thin and has good toughness and trauma resistance, so that it will not easily deform or break in the entire production process of the leather (such as printing patterns, cutting, etc.). Therefore, preferably, in order to ensure that the laser emitter 420 only cuts the leather layer without cutting through the underlying plastic carrier tape, the laser emitter 420 is preferably arranged to cut the leather layer to a depth of less than the thickness of the carrier tape layer. Figure 2 As shown, the contour cutting unit is also provided with a cutting depth detection module 430, and the laser emitter 420 can adjust the emission power and focal length according to the preset value and the detection result of the cutting depth detection module 430, thereby realizing accurate control of the cutting depth. Such a setting is mainly used to ensure that the leather layer and the plastic carrier tape layer are jointly transmitted in a bonded state, and one or more leather pieces that have completed contour cutting can be separated and used as needed later. Since the carrier tape layer is not cut and damaged, it can still stably adhere to and support the leather sheet during transmission, avoiding the separation displacement between the leather layer and the carrier tape layer after the cutting action is completed, thereby reducing the cutting quality defects caused by wrinkles, warping or deformation; the integrity of the carrier tape also provides good support for the transmission system, so that the entire leather roll remains relatively stable during long-distance transmission or between multiple processes, and is not easy to stretch, shake or deviate, thereby ensuring the accuracy during contour laser cutting and improving the alignment accuracy of the subsequent stamping and slicing unit 500; at the same time, since the carrier tape layer has not been segmented, the leather piece that has completed contour cutting still stays in place in a bonded state, and will not scatter or be disordered in position during transportation or transfer, which is very important for subsequent detection and slicing operation, and can reduce the difficulty of picking up and positioning in the automatic system; finally, for many downstream processes, if other processes (such as printing, marking) need to be completed first before slicing, it is an ideal choice to keep the carrier tape intact, and only when the final independent leather sheet is really needed, the carrier tape can be simply removed on the basis of the pre-cut contour, thereby obtaining a finished product with higher completeness and more orderly edges.
[0028] In some embodiments, the contour cutting unit not only comprises the first CCD camera 410 and the laser emitter 420, but also adds a moving mechanism, so that the first CCD camera 410 and the laser emitter 420 can move synchronously along the transmission direction of the leather roll and the pattern contour. The fixed end of the moving mechanism is fixed on the frame 100, and the first CCD camera 410 and the laser emitter 420 are jointly installed on the movable end of the moving mechanism. According to the application requirements, a stepping motor, a servo motor or the like can be used to drive the moving mechanism to move. When the leather roll is conveyed to the contour cutting unit area, the image information obtained by the CCD camera will be sent to the control system; according to the shape and trend of the pattern, the control system will calculate the laser cutting path, and real-time instruct the moving mechanism to drive the CCD camera and the laser emitter 420 to move synchronously, so as to closely cut the actual pattern.
[0029] As shown in Figure 1 The moving mechanism comprises a first sliding rail 441, a movable beam 442, a first driving member, a second sliding rail 443, a mounting block 444, a second driving member and the like, so as to realize smooth and accurate movement in multiple directions. The first sliding rail 441 is arranged on both sides of the frame 100 along the transmission direction of the conveying belt; the movable beam 442 is slidably connected to the first sliding rail 441 at both ends; the first driving member is arranged on the frame 100, and the driving end thereof is connected to the movable beam 442; the second sliding rail 443 is arranged on the movable beam 442 and arranged in a direction perpendicular to the transmission direction of the conveying belt; one end of the mounting block 444 is slidably connected to the second sliding rail 443, and the other end is connected to the first CCD camera 410 and the laser emitter 420; the second driving member is arranged on the movable beam 442, and the driving end thereof is connected to the mounting block 444. After the CCD camera obtains the pattern contour data, the control system sends coordinated driving instructions to the first driving member and the second driving member according to the required cutting path, so that the movable beam 442 and the mounting block 444 cooperate to move, and ensure that the laser emitter 420 is always aligned with the corresponding cutting line or pattern edge of the leather.
[0030] In some embodiments, the punching and cutting unit 500 is additionally provided with a holding assembly, in addition to the upper die plate 510, the bottom die seat 520 and the punching drive 530, to hold the leather roll tightly during the actual punching and cutting process, so as to reduce the wrinkles or displacement of the leather when subjected to vertical punching force. The holding assembly is generally composed of a holding block and a holding spring, and is installed on the lower surface of the upper die plate 510. A receiving groove is provided on the bottom surface of the upper die plate 510 to accommodate the holding block and the holding spring, so that the holding block and the holding spring are kept below the upper die plate 510 and do not affect the normal punching and cutting action of the upper die plate 510. The holding block is generally shaped to match the surface of the leather around the cutting position, and can be replaced or customized according to different product shapes or feeding and discharging processes. The holding spring is located between the holding block and the bottom of the receiving groove, and can provide a continuous and moderate pressing force to the leather before and after the punching action. During the downward movement of the upper die plate 510 by the punching drive 530, the holding block will contact the surface of the leather before or almost simultaneously with the cutting blade 511, and will laminate the leather on the bottom die seat 520, thereby reducing the slight displacement or shaking of the leather during the later cutting process. Reasonable spring stiffness design can ensure that the holding block will not damage the surface pattern or cause material deformation when pressing the leather. When the upper die plate 510 further moves downward so that the cutting blade 511 enters the corresponding slot hole 521 of the bottom die seat 520, the leather roll is successfully punched and cut into the predetermined shape of the piece. By adding the holding assembly, the leather can always be kept flat and in close contact during the punching and cutting process, effectively reducing the cutting errors caused by loose or shaking of the leather.
[0031] In some embodiments, in order to realize real-time monitoring and automatic management of the quality of profile cutting and punching and cutting, the device further comprises a quality inspection unit. The quality inspection unit is arranged at a position downstream of the punching and cutting unit 500, and is used to detect the leather pieces that have been cut or are to be cut, and automatically remove the pieces with cutting errors. The quality inspection unit comprises a detection module and a removal module. The detection module can comprise a visual detection component (such as a CCD camera or other image sensor) and a corresponding illumination light source, so as to clearly image each piece of leather. Image recognition software can also be used to determine whether there are abnormalities such as missed cutting, missing corners, tearing or displacement by comparing pre-set pattern profiles or size data. The removal module cooperates with the detection module to separate the unqualified pieces from the conveying belt or subsequent processes after detecting the unqualified pieces. The specific removal method can be diversified, such as mechanical hand grabbing, pneumatic push rod, suction cup 621 type suction, etc. For example, Figure 3As shown, the detection module includes a second CCD camera 610, and the removal module includes a removal robot 620, the movable end of which is provided with a suction cup 621. The second CCD camera 610 is usually fixed above the conveying belt, facing the high-definition image capturing of the leather sheet after profile cutting; the second CCD camera 610 is connected with the system controller, and through a special detection algorithm, the shape size, pattern position and edge quality of each finished product are quickly compared and identified, realizing real-time monitoring of cutting quality. The removal robot 620 can realize three-dimensional or multi-dimensional movement through a hinged robot arm or a linear sliding mechanism, and the movable end is equipped with one or more suction cups 621 to vacuum adsorb and lift when detecting unqualified sheets; when the detection module determines that the unqualified product, the robot moves to the specified coordinates according to the control signal, uses the suction cup 621 to suck up the target sheet, and places it in the waste recovery area or a special defective product container; for qualified products, the robot remains on standby or performs system self-checking in the idle state, without affecting the normal operation of the subsequent conveying belt.
[0032] In some embodiments, in order to effectively prevent the leather roll from shifting or warping during transmission, a plurality of compression rollers are arranged above the conveying belt assembly 200. The compression rollers are mainly used to tightly compress the leather on the surface of the conveying belt, ensuring that it remains flat and consistent during the processes of material feeding, profile cutting and punching. A plurality of compression rollers are regularly arranged above the conveying belt, each compression roller is installed on the frame 100 through a support or cantilever, and can slightly contact or apply pressure to the surface of the conveying belt. According to the needs, the compression roller can also be made into an adjustable structure, such as using a spring or air cylinder to apply force, so as to adapt to leather rolls of different thicknesses or materials. By arranging a plurality of compression rollers at intervals, the warping and shaking of the leather roll during high-speed or long-distance transmission can be effectively avoided, making the profile cutting and other fine processes more stable.
[0033] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
