Description

Technical Field

[0001] The utility model relates to the technical field of iron plate grabbing in the sheet metal industry, and in particular to a plastic pneumatic permanent magnetic chuck. Background Art

[0002] The existing suction cup inflation and deflation adjustment components (solenoid valves, vacuum generators, etc.) are set outside the suction cup. Since multiple suction cups are set on the plate adsorption rack on a single robotic arm, and a single suction cup requires multiple solenoid valves and vacuum generators for control, the arrangement of the deflation adjustment components outside the suction cup is relatively complicated, and subsequent maintenance is extremely inconvenient. Utility Model Content

[0003] The purpose of the utility model is to provide a plastic pneumatic permanent magnetic chuck, which is used to solve the problem that the existing chuck adopts an external inflation and deflation adjustment component, which makes it inconvenient to check the components during the later maintenance.

[0004] The present application provides a plastic pneumatic permanent magnetic suction cup, comprising: a cylinder body, a magnetic suction component slidingly arranged in the inner cavity of the cylinder body, a rear baffle arranged on the top of the cylinder body for limiting the sliding amount of the magnetic suction component, and an air inflation and deflation adjustment component arranged on the side wall of the cylinder body, the air inflation and deflation adjustment component comprising a first adjustment sub-component and a second adjustment sub-component, the first adjustment sub-component being used to adjust the pressure in the inner cavity of the cylinder body so that the magnetic suction component slides in the cylinder body, the second adjustment sub-component being used to enable the rubber suction cup at the bottom of the cylinder body to generate positive and negative pressure for adsorption or placement, wherein the cylinder body is obtained by integral injection molding of a plastic material.

[0005] Optionally, the magnetic attraction component includes a piston slidably arranged in the cylinder body and two semicircular magnets symmetrically arranged in the piston ring, and the magnets are used to magnetically attract the iron plate.

[0006] Optionally, the first regulating sub-component includes a first solenoid valve provided on the upper half of the cylinder side wall and a fourth solenoid valve provided on the lower half of the cylinder side wall. The first solenoid valve realizes the inflation and deflation operations on the inner cavity of the upper half of the cylinder through a first guide hole provided in the cylinder side wall, and the fourth solenoid valve realizes the inflation and deflation operations on the inner cavity of the lower half of the cylinder through a second guide hole provided in the cylinder side wall.

[0007] Optionally, the second regulating subcomponent includes a second solenoid valve, a vacuum generator provided in the side wall of the cylinder body, and a third solenoid valve, wherein the second solenoid valve is connected to the high-pressure air inlet end of the vacuum generator, and the low-pressure air inlet end of the vacuum generator is connected to a plurality of negative pressure air suction holes on the rubber suction cup through a third guide hole provided in the inner wall of the cylinder body, thereby causing the rubber suction cup to generate suction;

[0008] The third solenoid valve is communicated with a plurality of positive pressure exhaust holes on the rubber suction cup through a fourth guide hole provided in the side wall of the cylinder body.

[0009] The beneficial effects of the utility model are:

[0010] The utility model arranges the inflation and deflation regulating component on the cylinder body to avoid the problem of difficulty in subsequent maintenance and troubleshooting caused by arranging the inflation and deflation regulating component externally.

[0011] Secondly, existing suction cup systems use an aluminum alloy cylinder, which is heavy and places significant load pressure on the robot arm used with it. For example, the current robot has a load capacity of 80 kg, but after assembling 12 suction cups and their brackets, the total weight reaches 30 kg, occupying nearly 40% of the robot's load capacity. In contrast, the cylinder in this application is made of a single-piece plastic injection molding, which greatly reduces the mass of the suction cups and thus increases the robot's effective load capacity.
