Bottle grabbing device and control method thereof

Abstract

The invention provides a bottle grabbing device which is high in grabbing speed and stable in grabbing and a control method of the bottle grabbing device. The grabbing device comprises a seat body anda sucker arranged at the front end of the seat body. A ventilation hole is formed in the sucker, and a cavity communicating with the ventilation hole is formed in the seat body in the axial directionof the seat body. A negative-pressure channel and a positive-pressure channel communicating with the cavity are formed in the circumferential direction of the cavity. The negative-pressure channel communicates with the ventilation hole so that negative pressure can be formed by the ventilation hole, and the sucker can suck the bottom of a bottle so as to grab the bottle. A spindle is arranged inthe cavity in the axial direction of the cavity so as to block communication between the positive-pressure channel and the ventilation hole. The spindle is provided with an exhaust channel communicating with the ventilation hole so that the ventilation hole can recover the normal air pressure and the sucked bottle can be released. The spindle is sleeved with a piston assembly which can elasticallystretch and contract relative to the cavity when positive-pressure gas is led into the positive-pressure channel so as to block communication between the negative-pressure channel and the ventilationhole. The control method includes the negative-pressure forming step, the grabbing step and the releasing step.

Description

[0001] 【Technical field】 [0002] The invention relates to a bottle grasping device and a control method thereof. [0003] 【Background technique】 [0004] In order to achieve automatic handling and improve the processing efficiency of bottles, the traditional way is to use manipulators to grasp and transport the bottles. However, due to the relatively smooth structure of the bottle surface, it is easy to be unstable when using mechanical manipulators to grasp them. , and its crawl rate is slow. [0005] 【Content of invention】 [0006] The technical problem to be solved by the present invention is to provide a fast and stable bottle grabbing device and a control method thereof. [0007] The purpose of the present invention is achieved like this: [0008] A bottle grabbing device, comprising a base body and a suction cup arranged at the front end of the base body, the suction cup is provided with a vent hole, and the interior of the seat body is provided with a cavity communic...
