TECHNICAL FIELD
[0001] The present application relates to the field of laser cutting machine recognition, in particular, to a wide visual camera device for cloth laser cutting machine. BACKGROUND
[0002] The cloth laser cutting machine completes the accurate positioning and cutting of cloth patterns and patterns relying on visual recognition technology, and is widely used in the fields of flexible cloth processing such as garment fabric, home textile art, and decorative yarn. The recognition accuracy and running stability of the visual camera directly determine the finished product quality and processing yield of the cloth laser cutting. The existing visual camera is generally installed above the whole device. In order to improve the shooting area, the visual camera needs to be installed at a very high position, which occupies a large space. In addition, it is difficult to adapt and optimize the special fabrics such as light-transmitting cloth and light and thin yarn. The contrast of different background colors and light-transmitting cloth and light color patterns is low, which easily causes the edge of the pattern to be blurred, missed detection, false detection and other problems, greatly reduces the visual recognition accuracy, causes the laser cutting track to deviate, and produces defective products. The existing cloth laser cutting machine pads a contrast paper under the cloth when cutting cloth with similar colors, but a new paper needs to be replaced after each laser cutting, which increases the cost. The cloth is a flexible material, which is easily affected by uneven tension, equipment vibration, and conveying deviation during conveying and feeding, resulting in wrinkles and edge lifting. The pattern and pattern in the wrinkled area will be deformed, which exceeds the standard imaging range of the camera visual recognition, causing visual imaging distortion and pattern recognition disorder, seriously affecting the accuracy of laser cutting, and unable to guarantee the consistency of batch cloth processing. The existing visual camera device is fixedly installed and cannot be self-adaptively adjusted in height according to the cloth thickness, processing height, and imaging focal length requirements, and has poor adaptability.

[0020] The camera moving assembly 3 comprises a moving driving motor 32, the output end of the moving driving motor 32 is fixedly connected with a moving driving gear 33, the upper surface of the beam mounting plate 2 is fixedly connected with a moving rack 34, the moving rack 34 is in meshing connection with the moving driving gear 33, the upper surface of the beam mounting plate 2 is fixedly connected with a moving fixed slide rail 35, the lower surface of the camera moving mounting frame 31 is fixedly connected with a moving fixed slide block 36, and the moving fixed slide block 36 is in sliding connection with the moving fixed slide rail 35. The moving rack 34 and the moving driving gear 33 adopt a gear and rack meshing transmission mode, have high transmission precision and good running stability, can accurately control the horizontal moving stroke and position of the camera, and avoid the recognition dead angle caused by the moving deviation. The sliding connection of the moving fixed slide block 36 and the moving fixed slide rail 35 can greatly reduce the vibration and shaking in the moving process of the camera, and ensure that the global imaging picture is stable and has no ghosting.

The camera reflecting bottom plate 62 is inserted on the bottom plate fixing frame 61, and the camera reflecting bottom plate 62 is positionally installed by the connection of the bottom plate fixing block 63 and the bottom plate fixing frame 61. The camera bottom plate assembly 6 is a core adaptive structure, and different anodically oxidized colors of the camera reflecting bottom plate 62 can be flexibly changed according to different fabric characteristics. For low-contrast and difficult-to-identify fabrics such as light-transmitting fabrics, light and thin fabrics, and light color pattern fabrics, a high-contrast bottom color camera reflecting bottom plate 62 can be matched to effectively improve the imaging contrast of fabric patterns and the bottom plate, and solve the industry pain points of traditional fixed bottom plate imaging blur, low pattern edge recognition, and missed detection and false detection. For conventional dark color and high-contrast fabrics, a matching bottom color can be matched to ensure the imaging quality. At the same time, the bottom plate fixing block 63 adopts a precise position-limiting dismounting structure, which is convenient to dismount and position, has no displacement error after replacement, and can quickly adapt to batch and diversified fabric processing requirements to ensure the accuracy of the laser cutting track from the source.
[0025] The camera reflecting bottom plate 62 comprises a physical color-changing bottom plate and an electronic color-changing bottom plate. The physical color-changing bottom plate can change the color of the aluminum plate by an anodic oxidation process, or can paint different colors on the camera reflecting bottom plate 62 to adapt to different fabrics. The electronic color-changing bottom plate can use a lamp plate or a soft light film on the camera reflecting bottom plate 62 to increase the contrast of fabric details while ensuring that the light does not affect the recognition of the wide-format visual camera 8.
[0026] The conveying auxiliary assembly 7 comprises an auxiliary fixing frame 71 fixedly connected with the wide-format camera mounting frame 5, an auxiliary adjusting screw 72 threadedly connected on the auxiliary fixing frame 71, an auxiliary adjusting knob 73 fixedly connected to one end of the auxiliary adjusting screw 72, and a sliding rod connecting block 76 rotationally connected to the other end of the auxiliary adjusting screw 72. The auxiliary adjusting knob 73 can be rotated to drive the auxiliary adjusting screw 72 to rotate and drive the sliding rod connecting block 76 to vertically displace, so as to flexibly adjust the height of the auxiliary wheel and adapt to the flattening operation requirements of fabrics of different thicknesses.
[0027] The two ends of the adjusting limiting slide rods 75 are fixedly connected with two adjusting limiting slide blocks 76 on the slide rod connecting block 76, and the adjusting limiting slide block 74 is fixedly connected with the auxiliary fixing frame 71. The other ends of the two adjusting limiting slide rods 75 are fixedly connected with the conveying auxiliary mounting block 77, and the conveying auxiliary wheel 78 is rotatably connected with the conveying auxiliary mounting block 77. The adjusting limiting slide rod 75 cooperates with the adjusting limiting slide block 74 to realize limiting and guiding, so that the height adjusting process is stable and does not deviate. The conveying auxiliary wheel 78 can be attached to the cloth conveying surface, continuously smoothing the cloth wrinkles, edge lifting and relaxation deformation in the cloth feeding process, keeping the cloth in the camera recognition range always flat and relaxed, completely avoiding the pattern imaging distortion and recognition disorder caused by cloth deformation, effectively guaranteeing the integrity and standardization of each batch of cloth pattern imaging, and greatly improving the consistency and yield rate of batch cloth laser cutting.
[0028] The working principle of the cloth laser cutting machine and the use method of the wide-width visual camera are as follows: The camera moving drive motor 32 outputs power, and through the meshing connection of the camera moving drive gear 33 and the moving rack 34, under the limiting action of the moving fixed slide block 36 and the moving fixed slide rail 35, the camera moving mounting frame 31 moves horizontally. Through the conveying auxiliary assembly 7 on the wide-width camera mounting frame 5, the cloth can be flattened by the conveying auxiliary wheel 78. Through the lifting adjusting assembly 4, the lifting adjusting motor 41 drives the lifting adjusting screw 42 to drive the lifting adjusting mounting frame 43 to move up and down, which facilitates the cloth recognition of the wide-width visual camera 8. When the wide-width visual camera 8 recognizes the cloth, the camera moving assembly 3 moves reversely, and the camera moving mounting frame 31 returns to the initial position.
[0029] In the actual processing process, the cloth is sent to the cutting area through the transmission mechanism, and first passes through the conveying auxiliary wheel 78. At this time, the conveying auxiliary wheel 78 is pressed to abut against the cloth surface by adjusting the auxiliary adjusting knob 73. As the cloth is conveyed forward, the auxiliary wheel 78 rolls and flattens the protrusions or wrinkles on the cloth surface, so that the cloth area above the camera reflecting bottom plate 62 is in a flat state. Then, the wide-width visual camera 8 is driven by the moving assembly to scan across the cloth. Due to the reflecting effect of the bottom plate color, the boundary between the pattern and the background in the image signal obtained by the camera is clear. If the cloth thickness changes, the lifting adjusting screw 42 rotates to drive the camera to rise and fall along the lifting fixed slide rail 44, so that the camera lens always remains in the set object distance range.
