Description

Technical Field

[0001] This utility model belongs to the technical field of cutting auxiliary equipment, specifically relating to a product cutting line identification device. Background Technology

[0002] In the manufacturing process of rubber products, some products are formed by pressing and vulcanizing rubber material in a mold. In this process, specific areas on the inner wall of the mold cavity are pre-printed with markings indicating the target shape. After vulcanization, these markings form clear cutting lines. In subsequent processing steps, these cutting lines serve as positioning references, and the product is precisely cut along its contour to obtain individual finished products with specific heights or lengths. Therefore, accurately identifying the location of the cutting lines is a crucial step in ensuring cutting accuracy, guaranteeing product quality, and improving production efficiency.

[0003] Currently, the industry mainly relies on two methods for cutting line identification: The first is manual visual identification, where operators manually or semi-automatically trigger the cutting action after observing and judging the position of the cutting line. This method is highly susceptible to subjective factors such as operator fatigue and experience differences, leading to large fluctuations in accuracy and difficulty in ensuring product consistency. The second method is single-point sensor identification, which uses photoelectric, laser, or ultrasonic sensors to detect a single point on the product surface, determining the position by detecting differences in physical characteristics (such as height, reflectivity, and material density) at the cutting line. However, this method is limited by the single detection point, only obtaining local information and failing to comprehensively reflect the overall direction and spatial orientation of the cutting line. When faced with products of different specifications and curvatures, its adaptability is poor, and it is prone to identification deviations due to changes in product shape, leading to incorrect cutting positions, defective products, and seriously affecting production yield and equipment automation levels. Utility Model Content

[0008] The technical solution is further configured such that a linear drive element for driving the gripper to move linearly is provided between the base and the support platform, and a clearance notch is provided on the edge of the support platform to avoid the linear movement of the gripper.

[0009] The technical solution is further configured such that the centering fixture is mounted on the centering column, and the centering column is located above the support platform; The product is fitted around the centering fixture, and the outline shape of the centering fixture is adapted to the outline shape of the product.

Figures 1 to 2 The system includes a worktable 100, on which a rotary table 400 and a vision sensor 500 are mounted. The rotary table 400 is rotatably connected to the worktable 100. The rotary table 400 is equipped with a centering fixture 200 for positioning a product 900. The vision sensor 500 is mounted on a position adjustment assembly, and the installation position of the vision sensor 500 relative to the worktable 100 is adjustable.

[0020] Furthermore, the worktable 100 serves as the basic load-bearing structure of the device, providing a mounting support plane for other components. The installation position of the vision sensor 500 relative to the worktable 100 includes a lateral installation position and a longitudinal installation position. The lateral installation position is the distance between the vision sensor 500 and the product 900 (or the rotary table 400), and the longitudinal installation position is the installation height of the vision sensor 500.

[0021] Preferably, the vision sensor 500 uses an industrial camera.

[0022] By adopting the above technical solution, a vision sensor 500 is used for area scanning, replacing traditional manual visual inspection or single-point detection. This allows for the acquisition of complete image information of the entire circumference of the product 900, avoiding positioning deviations caused by single detection points or human error. Through the coordinated scanning of the rotating stage 400 and the vision sensor 500, it is ensured that the vision sensor 500 can synchronously acquire continuous, uniform, and complete product contour images during one rotation of the product 900. This fundamentally guarantees the accuracy and repeatability of cutting line recognition, achieving accurate cutting and improving the product's cutting pass rate. Furthermore, the position of the vision sensor 500 relative to the product 900 can be flexibly adjusted, allowing the device to easily adapt to various products of different specifications and curvatures, enhancing the device's versatility.

[0023] In a product cutting line recognition device of this embodiment, please refer to... Figures 1 to 4 The rotary table 400 includes a base 401 and a support platform 402. The base 401 is rotatably connected to the worktable surface 100. The support platform 402 is located above the base 401, and the support platform 402 is provided with a gripper 403 for clamping the centering fixture 200.

[0024] Furthermore, the lower surface of the worktable 100 is provided with a rotary drive element for driving the base 401 to rotate. The rotary drive element drives the base 401 to rotate through a synchronous belt and synchronous pulley assembly. The rotation of the base 401 is synchronized with the shooting action of the vision sensor 500.

[0025] By adopting the above technical solution, the base 401 can rotate the support platform 402 and the product 900 on it, which makes it easier for the vision sensor 500 to identify the product cutting line from different angles, thereby improving the accuracy and comprehensiveness of the identification.

[0032] Furthermore, the centering fixture 200 and the centering column 300 are detachably connected by bolts, and a limit block 406 is provided on the support platform 402. During operation, the centering column 300 is placed on the limit block 406 and clamped by the gripper 403.

[0033] By adopting the above technical solution, this design enables product 900 to be accurately positioned on centering fixture 200, ensuring good consistency of image data acquired by vision sensor 500, thereby improving the accuracy of cutting line recognition. The adaptable design of centering fixture 200 also prevents product 900 from shifting during rotation, ensuring the reliability of the detection results.
