A Pneumatic System for Light Inspection Machine

Abstract

The invention discloses a pneumatic system for a lamp inspection machine. The pneumatic system comprises a vacuum tank, vacuum air distribution devices, star wheel air distribution discs, electromagnetic valves, and a control device, wherein the vacuum tank is used for providing negative pressure, the vacuum tank is provided with a plurality of air distribution ports used for distributing the negative pressure; the vacuum air distribution devices are used for receiving the negative pressure distributed from the air distribution port and providing the negative pressure to electromagnetic valves, the vacuum air distribution devices are in one-to-one corresponding with the air distribution ports, and a plurality of installation holes used for installing electromagnetic valves are formed in the vacuum air distribution devices; the star wheel air distribution discs are used for adsorbing a to-be-lamp-detected object and are provided with a plurality of adsorption holes, the adsorption holescommunicate with the through holes of the electromagnetic valves through air distribution pipes, the star wheel air distribution discs is in one-to-one corresponding with the vacuum air distributiondevices; the electromagnetic valve is suitable for controlling the adsorption of the star wheel air distribution discs; and the control device is used for controlling the valves of the electromagnetic valves to be opened so as to enable the negative pressure inside the vacuum air distribution devices to enter the star wheel air distribution discs. According to the machine, the pneumatic system for the lamp inspection machine has the advantages of being large in vacuum suction force, clear in air path, convenient to maintain and the like.

Description

technical field [0001] The invention relates to the technical field of light inspection machines, in particular to a pneumatic system for light inspection machines. Background technique [0002] The light inspection machine is a kind of pharmaceutical machinery that detects drugs in order to ensure the safety of people's medication and prevent drug accidents. It is an inspection equipment for glass bottles after liquid filling. instrument, computer display. The principle of existing lamp inspection machines is: the bottle body on the lamp inspection machine is detected by the machine detection system (image acquisition and judgment), once an unqualified bottle is detected, an unqualified bottle signal is sent to the control on the lamp inspection machine The device is used to control the rejecting actuator so that it can remove unqualified bottles. Among them, unqualified bottles include defective bottles and bottles containing foreign matter. In the light inspection proc...
