Description

Sucking disc formula robotic arm

Technical Field

The utility model relates to a sucking disc formula robotic arm.

Background

At present, the mechanical arm is the earliest industrial robot and the earliest modern robot, can replace heavy labor of people to realize mechanization and automation of production, can operate under harmful environment to protect personal safety, and is widely applied to departments of mechanical manufacturing, metallurgy, electronics, light industry, atomic energy and the like. Therefore, we improve this and propose a suction cup type robot arm.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model provides a sucker type mechanical arm.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a sucker type mechanical arm comprises long H-shaped steel, short H-shaped steel, a fixing plate, a sucker body, a long air suction pipe and a short air suction pipe, wherein two pieces of long H-shaped steel and one piece of short H-shaped steel form an H-shaped support; each sucker body is integrally formed by a sucker and a vacuum cavity, and the inner wall of each sucker is circumferentially provided with a plurality of steps with different sizes from top to bottom; the vacuum cavities of the plurality of sucker bodies are communicated with and connected to the short suction pipe through the long suction pipe.

Furthermore, a filter screen is arranged at the joint of the vacuum cavity of the sucker body and the long suction pipe.

Further, the step height of the sucker body is 1-5 mm.

Has the advantages that:

1. the utility model is suitable for a not product of equidimension snatchs, snatchs stably, is difficult for droing.

2. The utility model discloses an inner wall at the sucking disc sets up different radial steps, can absorb not unidimensional product as required.

3. The utility model discloses a set up the filter screen in the junction of vacuum cavity and long breathing pipe, can avoid adsorbing blocking breathing pipe such as product in-process dust, debris.

Drawings

Fig. 1 is a schematic structural view of a suction cup type robot arm of the present invention;

FIG. 2 is an internal schematic view of the suction cup of the present invention;

in the figure: 1-long H-shaped steel, 2-short H-shaped steel, 3-fixed plate, 4-sucker body, 41-sucker, 42-vacuum cavity, 43-step, 5-long suction pipe and 6-short suction pipe.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

The utility model provides a sucker type mechanical arm, as shown in figure 1, which comprises a long H-shaped steel 1, a short H-shaped steel 2, a fixing plate 3, a sucker body 4, a long suction pipe 5 and a short suction pipe 6, wherein two long H-shaped steels 1 and one short H-shaped steel 2 form an H-shaped bracket, the fixing plate 3 is uniformly distributed on the two long H-shaped steels 1, and the sucker body 4 is fixed on the fixing plate 3; each sucker body 4 is integrally formed by a sucker 41 and a vacuum cavity 42, the inner wall of the sucker 41 is circumferentially provided with a plurality of steps 43 (figure 2) with different sizes from top to bottom, and the height is 1-5 mm; the vacuum chambers 42 of the plurality of suction cup bodies 4 are communicated with the short suction pipe 6 through the long suction pipe 5, and a filter screen is arranged at the joint of the vacuum chambers 42 of the suction cup bodies 4 and the long suction pipe 5.

In above-mentioned technical scheme, have sucking disc body 4 through 3 equipartitions of fixed plate on the long H shaped steel 1 of two parallels, to the product of equidimension not, only need select the sucking disc body 4 of different quantity can absorb, absorb stably, be difficult for droing.

In the above technical solution, the inner wall of the suction cup 41 of the suction cup body 4 is provided with the steps 43 with different radii, and each suction cup body 4 can meet the suction requirements of products with different sizes and small volumes.

In the above technical scheme, the filter screen is arranged at the joint of the vacuum cavity 42 and the long suction pipe 5, so that the blockage of the suction pipe caused by dust, impurities and the like in the process of adsorbing products can be avoided.

The working process is as follows:

(1) the sucker type mechanical arm is matched with an external mechanical arm for use;

(2) when the external manipulator reaches a designated position (the external manipulator sets a position parameter), the external manipulator starts to vacuumize and suck the suction disc 41 through the long suction pipe 5 and the short suction pipe 6;

(3) when the sucking disc 41 is contacted, the air between the sucking disc 41 and the product is pumped out by the built-in vacuumizing device of the external manipulator to reach a vacuum state, and the product is sucked up by the sucking disc type manipulator;

(4) at the moment, the built-in negative pressure sensor of the external manipulator detects the negative pressure in the long air suction pipe 5 and the short air suction pipe 6, and when the negative pressure does not reach the set value of the negative pressure sensor, the negative pressure sensor outputs a signal to the external manipulator to alarm and stop;

(5) when the external manipulator reaches a designated position (the external manipulator sets position parameters), the external manipulator sends a signal to disconnect the vacuumizing device, the vacuumizing and the air suction are stopped, and the product is loosened.

To the limitation of the protection scope of the present invention, it should be understood by those skilled in the art that, on the basis of the technical solution of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
