DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 6 A structure for picking up defective bricks by grading, comprising a mounting plate 1, a first electric push rod 2 is fixedly connected to the center of the bottom of the mounting plate 1, a positioning sleeve 3 is connected to the telescopic end of the first electric push rod 2, a plurality of groups of grabbing parts 4 are arranged around the positioning sleeve 3, and an auxiliary adsorption part 5 is connected to the opposite side of the plurality of groups of grabbing parts 4:

[0025] Furthermore, the auxiliary adsorption component 5 includes a second electric push rod 501 that is tilted, and the telescopic end of the second electric push rod 501 is rotatably connected to the mounting shell 502. A shunt pipe 505 is fixedly connected to the inside of the mounting shell 502, and one end of the shunt pipe 505 is fixedly connected to a connecting pipe 506. One end of the connecting pipe 506 extends to the outside of the mounting shell 502 and is fixedly connected to the air outlet end of the air pump 507. A plurality of first vacuum suction cups 509 are fixedly connected to the bottom of the shunt pipe 505, and the plurality of first vacuum suction cups 509 extend to the bottom of the mounting shell 502.

[0026] Through the first electric push rod 2 and the positioning sleeve 3 at the bottom of the mounting plate 1, the position of the grabbing member 4 can be flexibly adjusted to adapt to defective bricks of different sizes and positions to ensure the accuracy of grabbing. The design of multiple groups of grabbing members 4 can grab multiple bricks at the same time to improve efficiency. The auxiliary adsorption member 5 adjusts the angle through the second electric push rod 501, and cooperates with the shunt pipe 505 and the first vacuum suction cup 509 inside the mounting shell 502 to provide additional gripping force, especially for bricks with smooth surfaces or heavy weight. The first vacuum suction cup 509 can provide stable adsorption force to prevent bricks from slipping during the gripping process.

[0027] When it is necessary to grab a bad brick, the first electric push rod 2 will adjust the height of the positioning sleeve 3 according to the position of the brick, so that the grabbing member 4 is close to the brick. At the same time, the second electric push rod 501 of the auxiliary adsorption member 5 adjusts the angle of the mounting shell 502 so that the first vacuum suction cup 509 is aligned with the surface of the brick. The air pump 507 is started to provide negative pressure to the first vacuum suction cup 509 through the connecting pipe 506 and the shunt pipe 505, so as to adsorb the brick. At this time, the grabbing member 4 also acts on the brick at the same time, forming a double grabbing effect to ensure the stability of the brick during transportation. This grabbing structure is suitable for brick sorting scenes on automated production lines, especially those with strict requirements on brick size and shape, and requiring efficient and stable grabbing. Through precise positioning and strong grabbing force, effective sorting and processing of bad bricks are ensured.

[0028] Furthermore, the grabbing member 4 includes a plurality of fixed blocks 401 fixedly arranged on the surface of the positioning sleeve 3, the bottom of the plurality of fixed blocks 401 is rotatably connected to a first connecting rod 402, the first connecting rod 402 is rotatably connected to one end away from the fixed block 401 with a clamping claw 403, the clamping claw 403 is rotatably connected to the opposite side with a second connecting rod 404, and one end of the second connecting rod 404 is rotatably connected to the telescopic end of the first electric push rod 2.

[0029] When the first electric push rod 2 is extended, it pushes the second connecting rod 404, causing the second connecting rod 404 to rotate around the connection point with the clamping jaw 403, thereby driving the clamping jaw 403 to close and grab the brick. Conversely, when the first electric push rod 2 is retracted, the clamping jaw 403 will open and release the brick. The design of this connecting rod mechanism not only simplifies the structure of the grabbing member 4, but also ensures the smoothness and precision of the grabbing action.

[0030] Furthermore, a slider 503 is fixedly connected to one side of the mounting shell 502 , a slide bar 504 is slidably connected to the surface of the slider 503 , and a clamping claw 403 is fixedly connected to one side of the slide bar 504 .

[0031] In the process of grabbing bricks, the slide bar 504 slides along the slider 503 according to the actual position of the bricks to adjust the position of the clamping jaws 403. In this way, even if the position of the bricks is slightly offset, the clamping jaws 403 can be accurately aligned with the bricks through the fine adjustment of the slide bar 504 to achieve stable grabbing. In addition, the movement of the slide bar 504 can also help compensate for the slight deviation of the connecting rod mechanism that may occur during the grabbing process, thereby improving the accuracy and reliability of the overall grabbing structure.

[0032] Furthermore, the air pump 507 is fixedly arranged on the top of the installation shell 502 , a protective cover 508 is provided on the surface of the air pump 507 , and the bottom of the protective cover 508 is fixedly connected to the top of the installation shell 502 .

[0033] The bottom of the protective cover 508 is fixedly connected to the top of the mounting shell 502. This design ensures the stability of the protective cover 508 and prevents it from loosening or falling off during the operation of the equipment. At the same time, the fixed connection method is also conducive to the heat dissipation of the air pump 507 and maintains a good working condition.

[0034] Furthermore, multiple second vacuum suction cups 511 are equidistantly provided on the front and rear sides of the outside of the mounting shell 502, and one end of the multiple second vacuum suction cups 511 is fixedly connected to a connecting hose 510, and one end of the connecting hose 510 extends to the inside of the mounting shell 502 and is fixedly connected between the front and rear sides of the diversion pipe 505.

[0035] When the air pump 507 is started, the second vacuum suction cup 511 will also form a vacuum through the shunt pipe 505 and the connecting hose 510, and adsorb on the surface of the brick. In this way, in addition to the adsorption force provided by the first vacuum suction cup 509, the second vacuum suction cup 511 also participates in the grasping of the brick, forming a multi-point support, which improves the stability of grasping. Especially when handling heavy bricks or bricks with uneven surfaces, multi-point adsorption can significantly improve the success rate and safety of grasping.

[0036] Furthermore, a fixed sleeve 512 is provided on the surface of the multiple second vacuum suction cups 511, and the tops of the multiple fixed sleeves 512 are fixedly connected to the same horizontal plate 513, and the front and rear sides of the mounting shell 502 are fixedly connected to multiple third electric push rods 514, and the telescopic ends of the multiple third electric push rods 514 are fixedly connected to the opposite side of the horizontal plate 513.

[0037] When it is necessary to grab a brick, the third electric push rod 514 extends to push the horizontal plate 513 and the second vacuum suction cup 511 close to the brick until the second vacuum suction cup 511 is in close contact with the surface of the brick. At this time, the air pump 507 is started, and a vacuum is formed in the second vacuum suction cup 511 by connecting the hose 510 and the shunt pipe 505 to absorb the brick. During the handling process, the fine-tuning ability of the third electric push rod 514 can help maintain good contact between the second vacuum suction cup 511 and the brick, ensuring the stability and safety of the grabbing.

[0038] Furthermore, a plurality of mounting holes are equidistantly provided on the surface of the mounting plate 1, and the plurality of mounting holes are fixedly connected to the robot arm by positioning bolts.

[0039] The connection design between the mounting plate 1 and the robot arm is the basis for the efficient and accurate execution of tasks by the grasping system. The carefully designed mounting holes and positioning bolts not only enhance the stability of the grasping structure, but also ensure the precise docking with the robot arm, providing solid hardware support for high-quality grasping of defective products in graded brick picking.

[0040] Furthermore, the mounting plate 1 is made of steel.

[0041] Steel has good wear resistance and durability, and can withstand long-term use without being easily worn or corroded. In industrial environments, the gripping structure may be exposed to a variety of different materials and chemicals. The corrosion resistance of steel can effectively extend its service life, reduce the frequency of maintenance and replacement, and reduce operating costs.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
