Description

Technical Field

[0001] The utility model relates to the field of carbon box manufacturing and assembly, in particular to a rotary tensioning mechanism. Background Art

[0002] With the continuous improvement of industrial automation, higher requirements are being placed on the control of every detail in the production process. Especially in some links that require precise measurement and control, such as carbon ribbon tension testing, traditional manual or semi-automatic methods are becoming increasingly unable to meet the needs of modern production lines.

[0003] Currently, in many factories, the ribbon assembly process still relies on semi-automatic equipment or manual operations. Especially when testing ribbon tension, due to the lack of efficient automated solutions, semi-automatic equipment is often used, which is bulky and difficult to integrate into existing automated production lines. This situation not only leads to low production efficiency, but also easily introduces human errors due to the high manual involvement, affecting the consistency and reliability of product quality.

[0004] In addition, existing semi-automatic equipment often requires a larger space for layout, and due to its independent operation characteristics, its integration on the production line is low and it cannot be effectively connected with other production equipment, thus limiting the automation level and production efficiency of the entire production line.

[0005] Therefore, it is imperative to design a rotary tensioning mechanism. Utility Model Content

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a rotary tensioning mechanism, including a transmission frame, the transmission frame is equipped with a product carrier and a tensioning test assembly located on one side of the transmission frame, the product carrier is located in the tensioning test assembly, and the tensioning test assembly includes a limiting and pressing component, a tensioning embedding component and a test tensioning component, the product carrier is loaded with a carbon box, the carbon box is provided with a carbon ribbon roll, the limiting and pressing component is tightly pressed on the upper end of the carbon ribbon roll, the test tensioning component is arranged at the output end of the tensioning embedding component, the test tensioning component includes a servo motor, a clamping cylinder and a wheel tensioning head, the clamping cylinder is arranged at the output end of the servo motor, the wheel tensioning head is arranged at the output end of the clamping cylinder, the tensioning embedding component is used to drive the wheel tensioning head to extend into the carbon ribbon roll, and the servo motor drives the carbon ribbon roll to rotate through the wheel tensioning head to test the tensioning degree.

[0008] Based on the above, a beneficial effect of a rotary tensioning mechanism is to solve the problems of the existing technology of carbon ribbon tension testing equipment being large in size, difficult to integrate, inefficient and prone to human errors; it is mainly reflected in: the utility model sets up an integrated tensioning test component, which is located at a working position of the transmission frame to perform tension testing on the carbon ribbon roll in the product carrier. Compared with traditional equipment, it is more compact and can save valuable production space. At the same time, it is easy to integrate into the existing production line, thereby improving the space utilization rate of the overall production line; at the same time, the tensioning test component includes a limiting and pressing component, a tensioning embedded component and a test tensioning component.

A drive slot is provided at the end of the tensioning drive base plate away from the product carrier, and the servo motor is arranged at one end of the drive slot, and its output end passes through the drive slot.

[0011] Based on the above, the beneficial effect of tensioning the upper and lower cylinders is to adjust the vertical position of the wheel tensioning head to adapt to carbon ribbon rolls of different heights and enhance the adaptability of the equipment; the beneficial effect of the driving slot is to allow the servo motor output shaft to pass smoothly and ensure power transmission.

The clamping cylinder 332 is arranged at the output end of the servo motor 331, and the wheel tensioning head 333 is arranged at the output end of the clamping cylinder 332. The tensioning embedded component 32 is used to drive the wheel tensioning head 333 to extend into the carbon ribbon roll 41, and the servo motor 331 drives the carbon ribbon roll 41 to rotate through the wheel tensioning head 333 to test the tensioning degree.

[0025] The tensioning embedded component 32 includes a tensioning upper and lower cylinder 321 and a tensioning drive base plate 322. The tensioning upper and lower cylinders 321 are arranged on one side of the transmission frame 1, and the tensioning drive base plate 322 is arranged on the output end of the tensioning upper and lower cylinders 321.

The servo motor 331 is arranged at one end of the drive slot 3221, and its output end passes through the drive slot 3221.

[0026] The tensioning drive base plate 322 is provided with a rotating seat mounting groove 3222 at one end close to the product carrier 2 and is located directly below the carbon ribbon roll 41. The test tensioning component 33 also includes a rotating seat 334, which is fitted in the rotating seat mounting groove 3222 and meshed with the output end of the servo motor 331 through a belt. The clamping cylinder 332 is provided at the upper end of the rotating seat 334.

[0027] The limiting and pressing component 31 includes upper and lower cylinders 311 of the pressure plate and an upper limit pressure plate 312. The upper limit pressure plate 312 is arranged on the output end of the upper and lower cylinders 311 of the pressure plate.

[0032] Subsequently, the tensioning upper and lower cylinders 32 of the tensioning embedded component 32 adjust the height of the tensioning drive base plate 322 so that the wheel tensioning head 333 on it extends into the carbon ribbon roll 41, and the clamping cylinder 332 of the test tensioning component 33 drives the wheel tensioning head 333 to firmly clamp the carbon ribbon roll 41, and the servo motor 331 drives the rotating seat 334 to rotate. The servo motor 331 controls the rotation of the carbon ribbon roll 41 through the rotating seat 334, thereby testing its tensioning degree.
