[0003] With the development of automation technology, although some automated equipment has been used for the identification and positioning of feature points of tubular products, these devices are often complex in structure, high in cost, and difficult to adjust and maintain. In addition, some equipment may work unstably under certain conditions, or the positioning accuracy cannot meet the requirements of high-precision processing. Therefore, it is particularly urgent to develop an online automatic identification and positioning mechanism for tubular products with a simple structure, low cost, accurate positioning and easy maintenance, in order to meet the dual requirements of industrial production for high efficiency and high precision. To this end, the utility model proposes an online automatic identification and positioning mechanism for tubular products to solve the above problems. Utility Model Content

[0012] Preferably, the detection photoelectric is used to identify feature points on the tubular product, including but not limited to barcodes and QR codes.

[0013] Preferably, both the servo motor and the stepper motor are controlled by a control system.

Example

[0028] Please refer to the instruction manual Figure 1 The utility model provides a mechanism for automatically identifying characteristic points of tubular products online, specifically:

[0029] Main structure composition:

[0030] Servo motor 7: As the main power source, it is fixedly installed on the chassis and is responsible for providing the main power of the mechanism.

[0031] Linear sliding module 9: installed on the output end of the servo motor 7, responsible for realizing linear displacement driven by the servo motor 7.

[0032] Connecting plate 8: fixed on the linear sliding module 9, serving as a platform for connecting various components.

[0033] Longitudinal adjustment rod 6: fixedly mounted on one side of the connecting plate 8, with a detection photoelectric 2 mounted on one end for adjusting the height and position of the detection photoelectric.

[0034] The action cylinder 5 is arranged at one end of the longitudinal adjustment rod 6 , and a longitudinal adjustment plate 4 is arranged on the top to adjust the position of the longitudinal adjustment plate 4 .

[0035] Stepper motor 3: installed on one side of the longitudinal adjustment plate 4, with the output end extending downward and fixedly mounted with a roller 1, used for driving the tubular product to rotate.

[0036] Detection and identification system:

[0037] Detection photoelectric 2: used to identify feature points on tubular products, such as barcodes and QR codes, to ensure that the feature points can be accurately identified and located.

[0038] Control system:

[0039] Servo motor 7 and stepper motor 3: Both are controlled by a control system to achieve precise position control and speed adjustment to meet the positioning requirements of different tubular products.

[0040] Actuating cylinder 5: automatically adjusts the position of longitudinal adjustment plate 4 according to the control signal, thereby adjusting the contact pressure between roller 1 and the surface of tubular product to ensure stable contact between roller and product.

[0041] Roller material selection:

[0042] Roller 1: The surface material is selected from materials with wear resistance and friction coefficient to ensure effective contact and drive with the tubular product while reducing wear.

[0043] Directions:

[0044] First, the roller 1 and the detection photoelectric 2 are placed in the desired positions by adjusting the longitudinal adjustment plate 4 and the longitudinal adjustment rod 6. After the product reaches the predetermined position, the reciprocating rotation of the servo motor 7 drives the linear sliding module 9 to perform reciprocating linear motion. During its forward movement, the actuating cylinder 5 retracts, and the roller 1 contacts the product. Driven by the stepper motor, the product rotates. After the detection photoelectric 2 detects the feature points on the product, it stops rotating, and the actuating cylinder 5 extends to make the roller 1 leave the product. When the linear sliding module 9 moves forward to the set distance, the servo motor 7 reverses to make the linear sliding module 9 return to the origin, and repeats the previous action.
