Description

Technical Field

[0001] The utility model belongs to the technical field of PMI foam processing equipment, in particular to a PMI foam carving and feeding manipulator. Background Art

[0002] When processing PMI foam, large pieces of unprocessed blanks need to be placed on the milling machine processing center for carving. However, due to its heavy weight, it is usually transported by suction cups using manipulators and other equipment. However, after the polymerization of the PMI foam blank is completed, a lot of powder will remain on the surface. When the PMI foam blank is sucked by the suction cup, the residual powder will enter the air pipe, vacuum valve and solenoid valve through the suction cup, causing blockage, resulting in insufficient suction, and the PMI foam blank will fall, causing harm to personnel.

[0003] Therefore, it is necessary to design a suction cup that can absorb the PMI foam blank without causing blockage of the air pipe, vacuum valve and solenoid valve. Summary of the invention

[0006] Preferably, a spring is provided at the bottom of the inner cavity of the upper shell, and the lower end of the spring abuts against the top of the filter cartridge.

[0007] Preferably, a stud for connection is provided on the top of the upper shell.

[0008] The beneficial effects of the present utility model are as follows: By arranging a filter cartridge inside the upper housing, when the suction cup generates negative pressure, air will first pass through the filter cartridge and then enter the trachea, vacuum valve, and solenoid valve through the connector. The filter cartridge can effectively filter the powder impurities sucked by the suction cup, preventing them from entering the gas circuit system and causing blockages, thereby avoiding hazards to the lifting of PMI foam blanks; The upper housing and the base are connected by threads, which facilitates the replacement of the filter cartridge, making it convenient and fast.

[0011] Next, through embodiments and in combination with the drawings, the technical solutions of the present utility model will be further specifically described.

[0012] Embodiment: A PMI foam engraving loading manipulator, as Figure 1 shown, includes a loading suction cup. The loading suction cup includes a bottom cover 1, a mounting seat 2, and an upper housing 3. A ventilation hole 4 is provided at the middle position of the bottom cover 1. A limiting groove 5 is provided on the upper surface of the bottom cover 1. A filter cartridge 6 is provided in the limiting groove 5. The lower end of the filter cartridge 6 is snap-connected to the limiting groove 5. Abutting platform 7 is provided on the lower surface of the mounting seat 2. Threaded connection bosses 8 are provided at the outer ends of the upper and lower surfaces of the mounting seat 2. The abutting platform 7, the limiting groove 5, the ventilation hole 4, and the threaded connection boss 8 are all coaxially arranged with the mounting seat 2. The upper housing 3 is sleeved outside the filter cartridge 6, and the lower end of the upper housing 3 is connected to the threaded connection boss 8 on the upper surface of the mounting seat 2. A connector 9 for connecting the trachea is provided on the upper housing 3. A flexible suction cup 10 is provided on the abutting platform 7 of the mounting seat 2. The top of the suction cup is arranged on the lower surface of the abutting platform 7. The upper end of the bottom cover 1 is threadedly connected to the threaded connection column, and at the same time, the bottom of the suction cup is pressed on the abutting platform 7.

[0013] A spring 11 is provided at the bottom of the inner cavity of the upper housing 3. The lower end of the spring 11 abuts against the top of the filter cartridge 6; A stud 12 for connection is provided at the top of the upper housing 3.

[0014] Principle of the present utility model: During use, the feeding suction cup is fixed on the manipulator through the stud 12 provided on the upper housing 3, and an air pipe is connected to the joint 9. During use, the air pipe generates suction through devices such as a vacuum valve to suck the flexible suction cup 10 onto the surface of the PMI foam blank. When it comes into contact with the PMI foam blank, powder impurities will be sucked into the interior of the flexible suction cup 10. However, the powder impurities entering the filter cartridge 6 of the upper housing 3 through the ventilation holes 4 will be filtered and will not enter the air pipe along with the air flow. When it is necessary to replace the filter cartridge 6, you only need to remove the lower mounting seat 2 to take out the filter cartridge 6.

[0015] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model should be considered to fall within the protection scope of the present utility model.
