The one-way device generally includes an output shaft and a star wheel. One end of the star wheel has a round The gasket, half gasket and outer cover, the other end of the star wheel are the spring, spring seat, circlip seat and circlip in sequence.

At present, most manufacturers have begun to use a combination of assembly equipment and manual assembly for assembly. For example, the Chinese patent CN112296652B is a tooth assembly mechanism for a one-way device, including a frame, a workbench, and a workbench. It is equipped with a station transportation device, a gasket feeding device, a tooth feeding device, a spinning device and an output device.

The indexing assembly can grab and fit the positioning molds into the positioning molds. into the product mold. It can also only perform single-step installation of circlips and slip rings.

This type of equipment generally only performs the assembly of parts, requiring manual inspection or separate inspection with the help of other inspection equipment, which increases the transfer cycle and reduces production efficiency. Manual inspection of some parts is done through visual inspection, such as Manual visual inspection can easily cause fatigue when testing whether spring seats and circlip seats are installed backwards. When the number of tests is large, detection inaccuracies can easily occur.

Nowadays, some equipment has its own detection function, such as the Chinese patent CN112246538A, an oil filling mechanism for the one-way sleeve in the one-way device, including a frame, a workbench and a bracket arranged on the frame, and the workbench It is equipped with a conveying device, a detection device, an oil injection device and an output device.

Although this type of equipment can improve detection efficiency and detection accuracy, the detection part and the assembly part are generally integrated. The detection part will only work together when the assembly part is working. It is only suitable for use in the equipment's own process, and its versatility It is relatively low, and it is inconvenient to detect the assembly results in real time between processes. This may lead to the discovery that some parts are not up to standard and need to be reassembled, reworked or scrapped after the assembly is completed, thus causing a waste of time. If you directly purchase a machine with a detection function Assembling equipment will increase the cost of the enterprise.

In order to solve the above problems, it is necessary to develop a real-time detection system on the unidirectional axis automated production line.
