Carrying device on production line

The utility model relates to the field of household appliance production lines, in particular to a carrying device on a production line. The carrying device on the production line comprises a mechanical arm and a power device capable of driving the mechanical arm to move. The mechanical arm is fixed to the power device in an integrally detachable mode and comprises a supporting frame, wherein a proximity switch used for detecting workpieces and at least one sucker are fixedly arranged on the supporting frame, the proximity switch is connected with a controller, all the suckers are connected with a vacuum generator, and the controller can control the vacuum generator to generate compressed air to form pressure differences inside and outside the suckers after receiving signals of the proximity switch. According to the scheme, the mechanical arm is designed into a module mode, when products are switched on the production line, the mechanical arm is integrally switched and is put into production immediately after switching is completed, secondary debugging is avoided, switching is completed with the highest switching efficiency, the switching working time is greatly shortened, and more time can be used for production.
