Description

Technical Field

[0001] The utility model relates to the technical field of vacuum sucker equipment, in particular to a vacuum matrix sucker device. Background Art

[0002] Vacuum suction cup, also known as vacuum lifter, is generally a pneumatic component with a sealing lip. It forms a temporary sealed space after contacting the object to be sucked, and works by extracting or thinning the air in the sealed space to create a pressure difference between inside and outside.

[0003] In the prior art, the patent number is: CN220706208U provides a vacuum suction cup device, including a suction cup device body, the suction cup device body includes a fixed seat, a fixed column is welded on the top of the fixed seat, a limit plate is fixed on the fixed column, a threaded seat is movably installed on the fixed seat, the threaded seat is installed on the fixed seat through a bearing, a threaded column is rotatably installed inside the threaded seat, a suction cup is movably installed at the bottom of the fixed seat, and the top of the suction cup is installed on the threaded column through a bearing. When using this vacuum suction cup device, the limit suction cup can be preferentially contacted with the adsorption point. The limit suction cup itself is relatively soft, which is convenient for adsorption at the adsorption point. The limit suction cup can provide a friction point for the suction cup at a later time to avoid sliding caused by the smoothness of the suction cup and the adsorption position.

[0004] Although the above-mentioned vacuum suction cup device can achieve the effects of adsorption and quick disassembly through the settings of limit suction cups and threaded seats, it still has the following shortcomings in actual applications: the vacuum suction cup has adsorption force through the vacuum generated by compressed gas and vacuum generator, and there is a certain interval time between each adsorption of the workpiece, but it is extremely wasteful to keep the compressed air open to create a vacuum environment. Utility Model Content

[0005] The purpose of the utility model is to propose a vacuum matrix suction cup device in view of the problems existing in the background technology.

[0006] To achieve this purpose, the utility model adopts the following technical scheme: a vacuum matrix suction cup device, including a vacuum box, a vacuum generating assembly and a solenoid valve, the bottom wall of the vacuum box is evenly and evenly provided with a plurality of connecting holes, the bottom sides of the connecting holes are threadedly installed with adsorption assemblies, the interior of the vacuum box is snap-connected with a partition plate, and the partition plate and the interior of the vacuum box form a plurality of cavities evenly and evenly spaced, and each cavity corresponds to a connecting hole, and a flow hole is provided on one side of the partition plate close to the cavity, a sealing groove is provided on the top of the vacuum box, a sealing rubber ring is fixedly installed in the sealing groove, a top cover is installed on the top of the vacuum box by fastening screws, and the bottom of the top cover abuts against the top of the partition plate, a vacuum connecting pipe is fixedly inserted on the side wall of the vacuum box, the vacuum box is connected to the vacuum generating assembly through the vacuum connecting pipe, a gas connecting pipe is fixedly inserted on the top of the solenoid valve, the solenoid valve is connected to the vacuum generating assembly through the gas connecting pipe, a photoelectric sensor is fixedly installed on the front of the vacuum box, and the photoelectric sensor is electrically connected to the solenoid valve.

[0007] Preferably, the adsorption assembly comprises a vacuum logic valve threadedly mounted in the connecting hole, and an internal movable sleeve of the vacuum logic valve is provided with a sealing gasket.

[0008] Preferably, an adsorption disk is provided on the external bottom fixed sleeve of the vacuum logic valve.

[0010] Preferably, the vacuum generating assembly comprises a vacuum generator body, a connector 1 is fixedly plugged into the right side wall of the vacuum generator body, and the connector 1 is connected to the gas connecting pipe.

[0011] Preferably, a second connector is fixedly plugged into the bottom of the vacuum generator body, and the second connector is connected to the vacuum connecting pipe.

[0012] Preferably, a muffler is fixedly connected to the left side wall of the vacuum generator body.

[0013] The beneficial effects of the utility model are as follows: when the compressed gas reaches the solenoid valve through the air intake pipe, the solenoid valve coil is not electrically attracted, and the gas is not conductive. When it is necessary to absorb an object, the photoelectric sensor will approach the object, and then send out a connection signal, so that the solenoid valve coil is electrically attracted, and the compressed gas enters the vacuum generating component through the gas connecting pipe. The vacuum generating component generates a vacuum environment and then enters the vacuum box through the vacuum connecting pipe. Through multiple flow holes, the cavity between the partition plate and the vacuum box is made into a vacuum environment, and then the vacuum environment is transmitted to the adsorption plate through the vacuum logic valve to adsorb the workpiece. Through these settings, the device can not only automatically control the opening and closing of the solenoid valve according to the distance between the device and the object to avoid the waste of compressed gas, but also each adsorption component can have an independent cavity, so that the vacuum environment is more concentrated, thereby increasing the adsorption force of the adsorption plate.
