Wobble mechanism failure detection device and method

Abstract

The invention provides a wobble mechanism failure detection device and a wobble mechanism failure detection method. The wobble mechanism failure detection device comprises a motor, a transmission connecting rod and a connecting shaft disc, wherein one end of the transmission connecting rod is fixed on the connecting shaft disc of the motor and does reciprocating motion together with the connecting shaft disc; the wobble mechanism failure detection device also comprises a sensor which is arranged on the side part of the movable region of the transmission connecting rod and used for sensing whether the transmission connecting rod ruptures according to the movement of the transmission connecting rod. According to the wobble mechanism failure detection device and the wobble mechanism failure detection method, the abnormity existing in the transmission connecting rod of a wobble mechanism in a machine table can be detected in time, an alarm is given, the manufacturing cost and the product reject ratio are reduced, and the production efficiency is further improved.

Description

technical field [0001] The invention relates to a failure detection device and method of a shaking mechanism. Background technique [0002] Generally speaking, there are many reciprocating shaking mechanisms in the machine, but the current design of the response to their failure is not enough. Usually, the machine will only send out an alarm when the motor fails. According to past experience, the transmission link connected to the motor often breaks, but since the motor has not failed at this time, the machine cannot issue an alarm. [0003] figure 1 It is the front view of the existing machine. As shown in the figure, the machine table includes: a motor 10, which is used to provide shaking power; a motor shaft 11, which is used to connect the motor 10 and the connecting disc 12, and drive the moving of the connecting disc 12 through the shaking power transmitted by the motor 10 ; [0004] figure 2 It is a side view of the broken transmission link of the existing machi...

AI Technical Summary

Problems solved by technology

As shown in the figure, usually the transmission link will reciprocate in the moving area of ​​the transmission link according to the rotation direction of the motor. If the transmission link breaks during the period, since there is no alarm mechanism in the machine and the motor is not faulty, the , Only when there is a problem with the product will the abnormality of the machine be found, which not only increases the manufacturing cost and the defective rate of the product, but also reduces the production efficiency
